Wire harness manufacturing system and wire harness manufacturing method

A wire harness manufacturing system includes an assembly line that manufactures a wire harness and one or a plurality of supply devices that prepares to supply component magazines in which components of the wire harness are loaded in a holder to the assembly line. Each of the supply devices is capable of preparing a plurality of the component magazines which are different according to types of the components. The component magazines are capable of delivering from the supply devices to at least a part of the series of assembly steps in a state of being independent of both the assembly line and the supply device.

BACKGROUND OF THE INVENTION

Field of the Invention

The present invention relates to a wire harness manufacturing system including an assembly line that manufactures a wire harness through a series of assembly steps and supply devices that prepare to supply components of the wire harness to the assembly line, and a wire harness manufacturing method.

Description of Related Art

A wire harness used in an automobile and the like is manufactured by cutting an electrical wire into a predetermined length, crimping a terminal to an end thereof, forming a sub-harness through insertion of the terminal into a connector, bundling of a plurality of electrical wire-attached connectors, and attachment of a waterproof grommet, a protector, and the like, and assembling a plurality of sub-harnesses collectively. Such a series of assembly steps are generally performed on an assembly line.

In a manufacturing system, for example, a waterproof rubber plug (hereinafter, referred to as “waterproof plug”) that is a component of a wire harness is provided to an assembly line (directly connected to the assembly line) by a supply device (so-called hopper), in which the supply device aligns the waterproof plug in a predetermined direction and supplies the waterproof plug to the assembly line. In the supply device, the waterproof plug is filled in a funnel-shaped nozzle and drawn out from the nozzle by suction, and is thus supplied to the assembly line one by one with the orientation thereof adjusted (for example, see Patent Document 1: JP-A-2009-173448).[Patent Document 1] JP-A-2009-173448

According to a related art, in a supply device of a system that supplies a waterproof plug, a waterproof plug located at a deepest portion of a funnel-shaped nozzle (closest to a discharge opening of the nozzle) is sucked and taken out. More specifically, the waterproof plug has an orientation thereof adjusted along an axial direction of a pipe-shaped passage (pipeline) when passing through the passage through the discharge opening of the funnel-shaped nozzle. That is, the supply device merely has a function of taking out the waterproof plug located in vicinity of the discharge opening of the nozzle sequentially, and does not have a function of distinguishing a type (for example, various product Nos. different in size of diameter and length of the waterproof plug) of the waterproof plug before taking it out.

As a result, in the system, the type of the waterproof plug and that of the supply device correspond respectively. In other words, it is necessary to prepare a plurality of supply devices at the number of types (product Nos.) of a plurality of waterproof plugs to distinguish and deal these types (product Nos.).

Meanwhile, a wire harness typically has different structures for each type of vehicle, and has different structures even for the same type of vehicle according to grade, optional equipment, and the like. That is, a wire harness has various structures due to properties thereof. For example, various types (product Nos.) of waterproof plugs are used for wire harnesses of each specification.

However, it is not practical to provide a plurality of different (different for wire harnesses of each specification) assembly lines for each of wire harnesses having different structures in terms of cost and the like when the wire harnesses are actually manufactured. Therefore, it is typically required to manufacture different types of wire harnesses on a single assembly line.

As a result of such a requirement, for example, a plurality of supply devices different for each type of waterproof plug (different for waterproof plugs of each product No.) may be provided to a single assembly line. However, in this case, not only installation cost of the supply devices increases but also operation timings and the like of the plurality of supply devices need to be reset for wire harnesses of each specification, and preparation cost of the manufacturing system (and eventually manufacturing cost of the wire harnesses) is accordingly increased.

Additionally, the disadvantage associated with using a plurality of supply devices different for such each type (product No.) is not necessarily limited to supply of the waterproof plug, and may also occur to supply of components of a wire harness other than the waterproof plug.

SUMMARY

One or more embodiments provide a wire harness manufacturing system and a wire harness manufacturing method, in which manufacturing cost of a wire harness can be reduced as much as possible even when various types of components are to be supplied to an assembly line.

In order to achieve the above object, the “wire harness manufacturing system” according to the present invention is characterized by the following (1) to (4).(1) A wire harness manufacturing system comprising:

an assembly line that manufactures a wire harness and one or a plurality of supply devices that prepares to supply component magazines in which components of the wire harness are loaded in a holder to the assembly line,

wherein each of the supply devices is capable of preparing a plurality of the component magazines which are different according to types of the components, and

wherein the component magazines are capable of delivering from the supply devices to at least a part of the series of assembly steps in a state of being independent of both the assembly line and the supply device.(2) The wire harness manufacturing system according to (1),

wherein the supply devices continues to prepare the component magazines regardless of an operating state of the assembly line.(3) The wire harness manufacturing system according to (1) or (2),

wherein the supply devices prepare the component magazines, corresponding associating a consumption number of specific components on the assembly line per unit time to a manufacturing number of the component magazines per unit time loaded with the specific components.(4) The wire harness manufacturing system according to any one of (1) to (3),

wherein the supply devices comprises:a component tray on which the components are mounted;the holder;a transport mechanism that transports the components from the component tray to a loading port of the holder; anda loading mechanism that loading the components disposed in the loading port into the holder and forms the component magazines,

wherein the component tray is capable of mounting the components thereon separately according to types of the components, and

wherein the transport mechanism comprises:a camera that photographs the components placed on the component tray;a drive unit that includes a first moving body that is movable with being constrained by a first rail extending in a first direction connecting the component tray to the loading port, a second moving body that is movable while being constrained by a second rail provided on the first moving body so as to extend in a second direction intersecting the first direction, and drive arms that apply a driving force in at least one of the first direction and the second direction to the second moving body and that is capable of moving the second movable body along a movable plane defined by the first direction and the second direction; anda component moving unit that is supported by the second moving body and includes a component chuck movable in a third direction intersecting the moving plane and is capable of holding or releasing the components, and a motor that rotates the component chuck in the moving plane, and

wherein the drive unit transports the components from the component tray to the loading port based on an image photographed by the camera so that the components disposed in the loading port are aligned in a predetermined direction.

According to the wire harness manufacturing system with the above configuration in (1), the supply devices (each of the supply devices) are capable of supplying components to the assembly line via the component magazines, and of preparing a plurality of types of component magazines for each type of component. In other words, the supply devices are not dedicated devices different for each type of component (different for product No.), but general-purpose devices that can support various types (product No.) of components. That is, the supply devices and the types (product No.) of components are in a one-to-many relationship via the component magazine instead of a one-to-one relationship as in the system.

Therefore, as compared with the supply devices in the system, the number of supply devices can be reduced, so that installation cost of the supply devices can be reduced. Further, since the component magazine can be used simply in accordance with the specification of the wire harness (for example, since the component magazine corresponding to the type (product No.) of the component can be simply attached to the supply devices), preparation cost of the manufacturing system can be reduced without significantly resetting the supply devices. In other words, by using the component magazine, the assembly line (and accordingly the entire manufacturing system) can be flexibly adapted to various wire harnesses.

Therefore, the wire harness manufacturing system with such a configuration can reduce the manufacturing cost of the wire harness as much as possible even when various types of components are to be supplied to the assembly line.

As another effect, according to the wire harness manufacturing system SYS with such a configuration, the supply devices are indirectly connected to the assembly line (via a component magazine). Therefore, unlike the case where both the supply devices and the assembly line are directly connected as in the supply devices in the system, operation can be continued even if one of the supply devices and the assembly line malfunctions and operation thereof is stopped. In other words, the component magazine functions as a buffer (buffer mechanism) of the entire system. Therefore, the wire harness manufacturing system of such a configuration can improve the stability of the entire system.

All components of the wire harness do not have to be supplied via the above component magazines. For example, a component magazine may be utilized for a part of the components, and a supply device as those in the system may be included separately from the above supply devices.

According to the wire harness manufacturing system with the above configuration in (2), the supply devices continue preparing (manufacturing) component magazines regardless of an operation state of the assembly line (operating or stopped). As a result, for example, it is possible to stock the component magazines during a period in which the assembly line is stopped due to some problems, and to prepare a future demand for the component magazines. Therefore, the wire harness manufacturing system of such a configuration can improve the stability of the entire system.

According to the wire harness manufacturing system having the above configuration in (3), the component magazines can be manufactured in accordance with the actual number of consumed components. Therefore, the wire harness manufacturing system with such a configuration allows the supply devices to be operated efficiently in consideration of a post-process (a series of assembly steps on the assembly line). As a result, manufacturing cost of the wire harness can be further reduced.

According to the wire harness manufacturing system having the above configuration in (4), the component magazines have the function (the function of preparing the above component magazines) required for constructing the above manufacturing system. In other words, the supply devices having such a configuration are an example of actual supply devices that may be used to construct the above manufacturing system.

Further, in order to achieve the above object, the “wire harness manufacturing method” according to the present invention is characterized by the following (5).(5) A wire harness manufacturing method using one or a plurality of supply devices that prepare to supply component magazines in which components of a wire harness are loaded in a holder to an assembly line of the wire harness, the wire harness manufacturing method comprising:

preparing a plurality of the component magazines which are different according to types of the components in each of the supply devices;

delivering the component magazines from the supply devices to at least a part of the assembly line in a state of being independent of both the assembly line and the supply device; and

using the components picked up from the component magazines on the assembly line for manufacturing the wire harness.

According to the wire harness manufacturing method with the above configuration in (5), components are supplied to the assembly line via the component magazines and a plurality of types of component magazines are prepared for each type of component via the supply devices (each of the supply devices). In other words, the supply devices are not dedicated devices different for each type of component (different for product No.), but general-purpose devices that can support various types (product No.) of components. That is, the supply devices and the types (product No.) of components are in a one-to-many relationship via the component magazine instead of a one-to-one relationship as in the manufacturing method in the system.

Therefore, as compared with the manufacturing method in the system, the number of supply devices can be reduced, so that installation cost of the supply devices can be reduced. Further, since the component magazine can be used simply in accordance with the specification of the wire harness (for example, since the component magazine corresponding to the type (product No.) of the component can be simply attached to the supply devices), preparation cost of the manufacturing system can be reduced without significantly resetting the supply devices. In other words, by using the component magazine, the assembly line (and accordingly the entire manufacturing system) can be flexibly adapted to various wire harnesses.

Therefore, the wire harness manufacturing method with such a configuration can reduce the manufacturing cost of the wire harness as much as possible even when various types of components are to be supplied to the assembly line.

As another effect, according to the wire harness manufacturing method with such a configuration, the supply devices and the assembly line are indirectly connected (via a component magazine). Therefore, unlike the case where both the supply devices and the assembly line are directly connected as in the manufacturing method in the system, operation can be continued even if one of the supply devices and the assembly line malfunctions and operation thereof is stopped. In other words, the component magazine functions as a buffer (buffer mechanism) of the entire system. Therefore, the wire harness manufacturing method of such a configuration can improve the stability of the entire system.

According to one or more embodiments, in a wire harness manufacturing system and a wire harness manufacturing method, manufacturing cost of the wire harness can be reduced as much as possible even when various types of components are to be supplied to an assembly line.

The present invention has been briefly described above. Details of the present invention is further clarified by reading a mode for carrying out the invention described below with reference to attached drawings.

DESCRIPTION OF EMBODIMENTS

Hereinafter, a wire harness manufacturing system and a wire harness manufacturing method according to an embodiment of the present invention is described with reference to the drawings.

[Overall Configuration of Manufacturing System]

As illustrated inFIG. 1, a wire harness manufacturing system SYS according to the embodiment of the present invention includes an assembly line100on which components of a wire harness are assembled sequentially, and a plurality of (two in this embodiment) supply devices200that prepare to supply the components of a wire harness to the assembly line100. As to be described below, the supply devices200prepare component magazines (210ato210c,220ato220d) in which the components of a wire harness are loaded in a holder.

The assembly line100may include a lot production line110and/or a set production line120. In other words, the wire harness manufacturing system SYS according to the embodiment of the present invention is applicable to both the lot production line110and the set production line120. In the lot production line110(line A, line B, and line C), three types of terminal-attached electrical wires different for each type of waterproof plug (waterproof plugs A to C) are manufactured and used for each type of housing (housings A to C) as necessary, such that three types of waterproof connectors A to C are manufactured independently for each type. Meanwhile, in the set production line120(line D), a necessary number of three types of terminal-attached electrical wires different for each type of waterproof plug (waterproof plugs A to C) are manufactured and assembled to a specific housing (housing D), such that a waterproof connector D is manufactured.

The assembly line100(lot production line110, set production line120) illustrated inFIG. 1is a part of an assembly line for manufacturing a wire harness. Therefore, the waterproof connectors A to D assembled on the assembly line100are sent to a next step for manufacturing the wire harness.

The assembly line100is described in more detail below. First, a waterproof plug is a waterproof rubber plug for preventing water and the like from entering a terminal accommodating chamber of a housing. Hereinafter, a step of crimping an electrical wire attached (inserted) with a waterproof plug to a terminal is briefly described with reference toFIGS. 2A to 2D.

First, as illustrated inFIG. 2A, an electrical wire W in which a core wire W1is covered with an insulation coating W2is cut into a predetermined length (lengths different for wire harnesses of each specification). Next, as illustrated inFIG. 2B, a tip end portion of the core wire W1is exposed by removing (peeling) a tip end portion of the insulation coating W2. In this way, a waterproof plug U is inserted into the electrical wire W in which the tip end portion of the core wire W1is exposed.

In this embodiment, the waterproof plug U has a stepped cylindrical shape having a small diameter portion U1and a large diameter portion U2. The waterproof plug U is inserted into the electrical wire W from a large diameter portion U2side. As a result, as illustrated inFIG. 2C, the exposed core wire W1and the insulation coating W2are covered with the small diameter portion U1and the large diameter portion U2of the waterproof plug U, respectively. After the electrical wire W inserted with the waterproof plug U is placed at a predetermined position of a terminal T, as illustrated inFIG. 2D, the terminal T is crimped to the electrical wire W.

In this embodiment, the terminal T is a female terminal, and includes an electrical wire connecting portion T1for receiving a mating male terminal (not illustrated), a first crimping portion (a pair of crimping pieces) T2for crimping the core wire W1, and a second crimping portion (a pair of crimping pieces) T3for crimping the waterproof plug U and the insulation coating W2. Accordingly, as illustrated inFIG. 2D, the exposed core wire W1is crimped by the first crimping portion T2, and the insulation coating W2is crimped by the second crimping portion T3. Through the above step, the crimping of the electrical wire W to the terminal T is completed.

Referring again toFIG. 1, electrical wires A, B, and C have different types (for example, wire diameters, lengths, and materials). The waterproof plug A, the waterproof plug B, and the waterproof plug C have different types (for example, diameters, lengths, surface shapes, and materials). Additionally, the housing A, the housing B, the housing C, and the housing D have different types (for example, shapes, materials, types and numbers of terminal-attached electrical wires to be inserted).

On the line A, a tip end portion of a core wire of the electrical wire A is exposed when the electrical wire A is cut to a predetermined length, and then the waterproof plug A is inserted into the electrical wire A in which the tip end portion of the core wire is exposed, and then a terminal is crimped to the electrical wire A inserted with the waterproof plug A. Similarly, on the lines B and C, a terminal is crimped to the electrical wire B after the waterproof plug B is inserted, and a terminal is crimped to the electrical wire C after the waterproof plug C is inserted. Next, the electrical wire A crimped by the terminal is assembled to the housing A (the terminal of the electrical wire A is inserted into a terminal accommodating chamber of the housing A), such that the waterproof connector A is manufactured. The electrical wires A, B, and C crimped by terminals are assembled to the housing B (the terminals of the electrical wires A, B, and C are inserted into a terminal accommodating chamber of the housing B), such that the waterproof connector B is manufactured. Additionally, the electrical wires B and C crimped by terminals are assembled to the housing C (the terminals of the electrical wires B and C are inserted into a terminal accommodating chamber of the housing C), such that the waterproof connector C is manufactured.

InFIG. 1, the electrical wires A, B, and C crimped by terminals are mutually used on a plurality of lines A, B, and C. However, the assembly line100may be configured such that only the electrical wire A crimped by the terminal is used on the line A, only the electrical wire B crimped by the terminal is used on the line B, and only the electrical wire C crimped by the terminal is used on the line C.

On the line D, tip end portions of core wires of the electrical wires A, B, and C are exposed when the electrical wires A, B, and C are cut to a predetermined length respectively, and then the waterproof plugs A, B, and C are inserted into the electrical wires A, B, and C in which the tip end portions of the core wires are exposed, and then terminals are crimped to the electrical wires A, B, and C inserted with the waterproof plugs A, B, and C. That is, the electrical wires A, B, and C crimped by the terminals are manufactured collectively. Next, the electrical wires A, B, and C crimped by the terminals are inserted into corresponding terminal insertion holes of the housing D, respectively, such that the waterproof connector D is manufactured.

On the lines A to D, waterproof plug magazines210ato210cformed by a waterproof plug supplier210are supplied to a step of inserting corresponding waterproof plugs. Similarly, housing magazines220ato220dformed by a housing supplier220are supplied to a step of inserting terminals into corresponding housings. Here, the waterproof plug magazines210ato210crefer to holders in which a plurality of waterproof plugs of the same type are loaded in a row in a state of being aligned in the same orientation (seeFIG. 3). The housing magazines220ato220drefer to holders in which a plurality of housings of the same type are loaded in a row in a state of being aligned in the same orientation (not illustrated).

Hereinafter, the waterproof plug magazines210ato210care briefly described with reference toFIGS. 3 and 4. In the waterproof plug magazine210a(the waterproof plug magazines210band210calso have similar configurations) illustrated inFIGS. 3 and 4, a plurality of waterproof plugs of the same type are loaded in a row in a cylindrical holder20having a circular cross section made of a resin that can be easily deformed in a state of being aligned in the same orientation. As illustrated inFIG. 4, the waterproof plug magazine210ais formed by inserting each waterproof plug U into the holder20sequentially by the waterproof plug supplier210from an insertion opening21(opening) on one end side of the holder20in a state of facing a direction of inserting the small-diameter portion U1.

A fixing jig22is provided near the insertion opening21of the holder20. As to be described below, the fixing jig22is used when the holder20is mounted and fixed to a predetermined position of the waterproof plug supplier210to form the waterproof plug magazine210a.A cover23is provided at an opening on another end side of the holder20. The cover23has a function of preventing the waterproof plug U loaded in the holder20from dropping from the opening on the other end side of the holder20.

Referring back toFIG. 1, the waterproof plug supplier210forms a plurality of types of waterproof plug magazines210ato210cfor each type of waterproof plug. In this embodiment, the waterproof plug supplier210forms the waterproof plug magazine210ain which only a plurality of waterproof plugs A are loaded, the waterproof plug magazine210bin which only a plurality of waterproof plugs B are loaded, and the waterproof plug magazine210cin which only a plurality of waterproof plugs C are loaded.

The formed waterproof plug magazines210ato210care picked up from the waterproof plug supplier210and are respectively supplied to corresponding lines in an independent state (in a state of being independent from both the waterproof plug supplier210and the assembly line100). In this embodiment, the waterproof plug magazine210ais supplied to the step of inserting the waterproofing stopper to the lines A and D, the waterproof plug magazine210bis supplied to the step of inserting the waterproofing stopper to the lines B and D, and the waterproof plug magazine210cis supplied to the step of inserting the waterproofing stopper to the lines C and D.

In this way, the types of waterproof plug magazines210ato210cformed by the waterproof plug supplier210are delivered to corresponding steps of corresponding lines from the waterproof plug supplier210in a state of being independent from both the assembly line100and the waterproof plug supplier210. Taking the waterproof plug out from the waterproof plug magazine on each line and supply of the waterproof plug magazine to each assembly line may be performed automatically using a device or be performed manually.

The waterproof plug magazines210ato210chave been described above. The same applies to the housing magazines220ato220d.That is, the housing supplier220forms a plurality of types of housing magazines220ato220dfor each type of housing. In this embodiment, the housing supplier220forms the housing magazine220ain which only a plurality of housings A are loaded, the housing magazine220bin which only a plurality of housings B are loaded, the housing magazine220cin which only a plurality of housings C are loaded, and the housing magazine220din which only a plurality of housings D are loaded.

The formed types of housing magazines220ato220dare picked up from housing supplier220and supplied respectively to corresponding lines in an independent state (in a state of being independent from both the housing supplier220and the assembly line100). In this embodiment, the housing magazine220ais supplied to a step of inserting the terminal to the line A, the housing magazine220bis supplied to a step of inserting the terminal to the line B, the housing magazine220cis supplied to a step of inserting the terminal to the line C, and the housing magazine220dis supplied to a step of inserting the terminal to the line D.

In this way, the types of housing magazines220ato220dformed by the housing supplier220are delivered to corresponding steps of corresponding lines from the housing supplier220in a state of being independent from both the assembly line100and the housing supplier220. Taking the housing out from the housing magazine on each line and supply of the housing magazine to each assembly line may be performed automatically using a device or be performed manually.

The waterproof plug supplier210can continue to form and prepare the waterproof plug magazines210ato210cregardless of an operation state of the assembly line100(no matter the assembly line100is operating or stopped). This makes it possible to stock the waterproof plug magazines210ato210cduring a period in which the assembly line100is stopped due to such as a problem, and to prepare a future demand for the waterproof plug magazines210ato210c.The same applies to the housing supplier220.

Further, the waterproof plug supplier210is capable of associating the number of consumed waterproof plug magazines210ato210con the assembly line100per unit time and the number of manufactured waterproof plug magazines210ato210cper unit time for each type of the waterproof plugs A to C, and of forming and preparing the waterproof plug magazines210ato210cat the same time. Accordingly, the waterproof plug magazines210ato210ccan be manufactured in accordance with the actual number of consumed waterproof plugs A to C for each type of the waterproof plugs A to C. The same applies to the housing supplier220.

The wire harness manufacturing system SYS according to the embodiment of the present invention has been described above with reference toFIGS. 1 to 4. Hereinafter, a configuration of the waterproof plug supplier210is described in detail with reference toFIGS. 5 to 16. Additionally, the housing supplier220may be configured similarly to the waterproof plug supplier210, and description thereof is omitted accordingly.

[Configuration of Waterproof Plug Supplier]

As illustrated inFIG. 5, the waterproof plug supplier210is provided on an upper surface310of a movable work table300. Therefore, the waterproof plug supplier210can be moved with respect to arrangement of the lines A to D as appropriate.

The waterproof plug supplier210includes a component tray10on which the waterproof plug U is placed, the above holder20(seeFIGS. 3 and 4) used for forming the waterproof plug magazine, a transport mechanism30for transporting the waterproof plug U from the component tray10to vicinity of the insertion port21of the holder20, and a loading mechanism40for loading the waterproof plug U disposed in the vicinity of the insertion port21of the holder20into the holder20and forming the waterproof plug magazine. Hereinafter, as illustrated inFIG. 5, an x-axis direction, a y-axis direction, and a z-axis direction orthogonal to each other are defined for convenience of illustration.

As illustrated inFIGS. 5 and 8, the component tray10is a disk-shaped member made of a resin. The component tray10is fixed to be rotatable in a circumferential direction along the x-y plane at a position above a predetermined distance from the upper surface310via a stay51erected upward (a positive direction of the z-axis) from a central part of the upper surface310of the work table300. Adjustment of an orientation of the component tray10in the circumferential direction may be automatically performed using a device or be performed manually.

As illustrated inFIG. 8, a plurality of grooves11are formed in an upper surface of the component tray10. In this embodiment, four grooves11having the same shape are formed independently at an equal interval in the circumferential direction. A plurality of types of waterproof plugs corresponding to specifications of wire harnesses are separately placed in the grooves11. During operation of the waterproof plug supplier210, the orientation of the component tray10in the circumferential direction is adjusted such that each of the four grooves11is located on a positive side of the x-axis, a negative side of the x-axis, a positive side of the y-axis, and a negative side of the y-axis, and only a waterproof plug placed in a groove11(hereinafter referred to as a “selected groove”) that is on the negative side of the x-axis is supplied to form the waterproof plug magazine.

As illustrated inFIGS. 5, 6, and 11, the insertion opening21(see alsoFIGS. 3 and 4) of the holder20is inserted into an attachment portion52a(a through hole not illustrated that extends in the x-axis direction) that is provided on an upper surface of the stay52erected upward from an edge of the upper surface310of the work table300in the negative side of the x-axis, such that the fixing jig22(see alsoFIGS. 3 and 4) is detachably fixed to the attachment portion52a.Accordingly, an end portion of the holder20is detachably fixed to the attachment portion52a.

As illustrated inFIG. 5, the transport mechanism30includes a camera31, a drive unit32, and a component moving unit33. The camera31is fixedly disposed above the groove (selected groove) of the component tray10via a stay (not illustrated) fixed to the upper surface310of the work table300. The camera31photographs the waterproof plug U placed in the groove11(selected groove) from above.

The drive unit32is a part related to operation of moving a suction nozzle68to be described below along the x-y plane for holding the waterproof plug U. A configuration related to the drive unit32is described below.

As illustrated inFIGS. 5, 10, 11, and the like, a pair of first rails54extending parallel to each other at a predetermined distance along the x-axis direction is fixed to a position above the component tray10via a plurality of stays53on the upper surface310of the work table300that are erected upward from a peripheral part of the component tray10.

The pair of first rails54is provided with a first moving body55that is movable in the x-axis direction (corresponding to “first direction” of the present invention) while being constrained by the pair of first rails54so as to straddle the pair of first rails54. A second rail56that extends in the y-axis direction (corresponding to “second direction” of the present invention) is provided on an upper surface of the first moving body55.

The second rail56is provided with a second moving body57that is movable in the y-axis direction while being restrained by the second rail56. As a result, the second moving body57is arbitrarily movable along the x-y plane. As to be described below, the suction nozzle68is indirectly fixed to the second moving body57.

One end portions of a pair of rod-shaped first drive arms58are coupled to end portions on both sides of the second movable body57in the y-axis direction so as to be relatively rotatable along the x-y plane. One end portions of a pair of rod-shaped second drive arms59are coupled to other end portions of the pair of first drive arms58so as to be relatively rotatable along the x-y plane.

A pair of electric motors62are fixed, at a predetermined interval, to a stay61erected upward from an edge of the upper surface310of the work table300on the positive side of the x-axis along the y-axis direction. Motor shafts63of the pair of electric motors62project separately from an upper surface of the stay61toward the positive direction of the z-axis. Other end portions of the pair of second drive arms59are integrally connected to the pair of motor shafts63separately.

The drive unit32is configured as described above. As a result, a driving force in the x-axis direction and the y-axis direction is applied from the pair of first driving arms58to the second moving body57by individually adjusting rotation angles of the motor shafts63of the pair of electric motors62, such that a position of the second moving body57in the x-y plane can be arbitrarily adjusted.

The component moving unit33is a part related to operation of moving the suction nozzle68for holding the waterproof plug U along the z-axis direction and operation of rotating the suction nozzle68extending in the z-axis direction around its axis. A configuration related to the component moving unit33is described below.

As illustrated inFIG. 10, a stay64is fixed to the second moving body57to extend in the negative direction of the x-axis. An electric motor65is fixed to the stay64. A motor shaft (not illustrated) of the electric motor65protrudes from a lower surface of the stay64toward the negative direction of the z-axis. An L-shaped bracket66is integrally coupled to the motor shaft of the electric motor65.

The rod-like suction nozzle68is provided in a suspended portion of the bracket66that extends in the negative direction of the z-axis via a drive mechanism67so as to be relatively movable along the z-axis direction (corresponding to “third direction” of the present invention). By controlling the driving mechanism67, a position of the suction nozzle68in the z-axis direction with respect to the bracket66(in other words, the second moving body57) can be adjusted.

An axis of the suction nozzle68is located coaxially with that of the motor shaft of the electric motor65. Therefore, the suction nozzle68is rotated around the axis (in the x-y plane) by adjusting a rotation angle of the motor shaft of the electric motor65, such that the position of the suction nozzle68in the rotation direction can be adjusted.

A through hole69is formed in the suction nozzle68along the axis thereof. An upper end opening of the through hole69is attached with an end portion of a suction hose (not illustrated), and another end portion of the hose is connected to a vacuum pump (not illustrated) for suction. A lower end of the through hole69functions as a suction opening71. By controlling the vacuum pump, the suction nozzle68is capable of sucking and holding the waterproof plug U in vicinity of the suction opening71, and of releasing the held waterproof plug U.

The transport mechanism30has been described above. Next, a configuration related to the loading mechanism40is described.

As illustrated inFIGS. 6 and 9, a shaft73having a rectangular cross section (square shape) is fixed to a stay72on the upper surface310of the work table300that is erected upward from a part between the component tray10and the stay52so as to extend in the negative direction of the x-axis and to be rotatable appropriately around a shaft center thereof. The adjustment of the position of the shaft73in the rotation direction may be automatically performed using a device or may be performed manually. Additionally, the stay52inFIG. 6is omitted inFIG. 9for convenience of illustration.

Particularly, as illustrated inFIG. 9, brackets74are fixed at four edges corresponding to four sides of the shaft73at a tip end portion thereof (end portion in the negative direction of the z-axis) so as to extend in the negative direction of the x-axis. Each of the brackets74is formed with a through hole75extending in the x-axis direction in a negative side part of the x-axis, and a groove76that continuously extends in the positive direction of the x-axis from the through hole75and opens upward is formed in a positive side part of the x-axis. The waterproof plug U carried by the suction nozzle68is placed in grooves76.

The four brackets74correspond to the four grooves11of the component tray10, respectively. That is, the inner diameter of through hole75has a size corresponding to a maximum outer diameter of the waterproof plug U placed in the corresponding groove11among the four grooves11of the component tray10. Therefore, in this embodiment, inner diameters of through holes75of the four brackets are different from each other.

During operation of the waterproof plug supplier210, the position of the shaft73in the rotation direction is adjusted such that each of the four brackets11is located on the positive side of the y-axis, the negative side of the y-axis, a positive side of the z-axis, and a negative side of the z-axis, and only a bracket74(hereinafter referred to as a “selected bracket”) that is placed in the positive side of the z-axis is supplied to form the waterproof plug magazine.

That is, as illustrated inFIG. 6, the bracket74(selected bracket) is disposed close to the positive side of the x-axis of the attachment portion52aof the stay52, and the through hole75of the bracket74(selected bracket) is disposed coaxially with the through hole in the attachment portion52a.As a result, the waterproof plug U placed in the groove76of the bracket74(selected bracket) is pushed toward the negative direction of the x-axis, such that the waterproof plug U passes through the through hole75of the bracket74(selected bracket), the through hole of the mounting portion52a,and the insertion opening21(seeFIGS. 3 and 4) of the holder20and is loaded in the holder20.

A moving member77having a stepped cylindrical shape outer periphery is inserted into the shaft73so as to be movable relative to the shaft73in the x-axis direction and not rotatable relatively. Four push-in bars78are fixed at an end surface of the moving member77on the negative side of the x-axis, so as to protrude toward the groove76of the corresponding bracket74in negative direction of the x-axis.

Therefore, in the state illustrated inFIG. 6, the moving member77is moved relative to the shaft73on the negative direction side of the z-axis, such that a tip end surface of a push-in bar78(hereinafter, referred to as “selected push-in bar” particularly) corresponding to the bracket74(selected bracket) is pushed into the waterproof plug U placed in the groove76of the bracket74(selected bracket) toward the negative direction of the x-axis, and the waterproof plug U can be filled in the holder20consequently.

A pair of drive mechanisms79capable of adjusting positions of a pair of grasping members81in the x-axis direction are fixed to the stay72. The pair of grasping members81grasps a flange portion of the moving member77on the positive side of the x-axis. Therefore, the position of the moving member77in the x-axis direction can be adjusted by controlling the pair of driving mechanisms79. In other words, by controlling the pair of drive mechanisms79, the waterproof plug U placed in the groove76of the bracket74(selected bracket) can be pushed toward the negative direction of the x-axis via the selected push-in bar78.

The pair of electric motors62, the electric motor65, the drive mechanism67, the drive mechanisms79, and the vacuum pump described above are controlled by a control device (microcomputer) (not illustrated). The configuration of the waterproof plug supplier210has been described above.

[Operation of Waterproof Plug Supplier]

Next, operation when the waterproof plug supplier210forms the waterproof plug magazine is described with reference to a flowchart illustrated inFIG. 12. The processing illustrated in this flowchart is performed by the control device described above.

Before starting this processing, a plurality of waterproof plugs U of a type corresponding to the waterproof plug magazine to be formed are placed in the groove11(selected groove) of the component tray10, and the holder20and the bracket74(selected bracket and selected push-in bar78) need to be switched to those corresponding to the type of waterproof plug U. As illustrated inFIG. 7, the waterproof plug U that has a stepped cylindrical shape having the small diameter portion U1and the large diameter portion U2is used, which is similar as that illustrated inFIG. 4. As illustrated inFIG. 4, the waterproof plug U is sequentially inserted into the holder20with the small diameter portion U1side facing in the insertion direction (the negative direction of the x-axis).

First, in Step S5, it is determined whether or not the suction nozzle68is at an initial position. Here, as illustrated inFIG. 14, the initial position refers to a position where the suction nozzle68is disposed above the groove76(hereinafter, also referred to as a “magazine insertion opening”) of the bracket74(selected bracket).

When the suction nozzle68is at the initial position (“Yes” in Step S5), the processing directly proceeds to Step S15. When the suction nozzle68is not at the initial position (“No” in Step S5), the suction nozzle68is moved to the initial position in Step S10, and the processing then proceeds to Step S15.

In Step S15, the plurality of waterproof plugs U placed in the groove11(selected groove) of the component tray10are photographed by the camera31. As described above, the camera31photographs when the suction nozzle68is at the initial position based on a fact that, when the suction nozzle68is at the initial position, the driving unit32and the component moving unit33are located outside an imaging range of the camera31(accordingly, the driving unit32and the component moving unit33do not interfere with the photographing).

Next, in Step S20, pattern matching is performed based on the photographed image. In this embodiment, the pattern matching refers to operation of specifying positions (x-y coordinates) of the plurality of waterproof plugs U placed in the groove11(selected groove).

Next, in Step S25, based on the result of the pattern matching, the waterproof plug U to be gripped is determined. Subsequently, in Step S30, an inclination θ of the determined waterproof plug U is specified. As illustrated inFIG. 13, the inclination θ refers to an angle formed by a direction in which the waterproof plug U is placed in the magazine insertion opening (a direction in which the small diameter portion U1faces the negative direction of the x-axis) and the direction of the determined waterproof plug U.

Next, in Step S35, the suction nozzle68is moved along the x-y plane until right above the determined waterproof plug U while being rotated by an angle θ (see (1) inFIG. 14). Subsequently, in Step S40, the suction nozzle68is lowered in the negative direction of the z-axis (see (2) inFIG. 14). As a result, the suction opening71of the suction nozzle68is located right above the determined waterproof plug U. In this state, the determined waterproof plug U is sucked to the suction opening71of the suction nozzle68.

Subsequently, in Step S45, the suction nozzle68is moved to the initial position while being reversely rotated at the angle θ (see (3) inFIG. 14). Next, in Step S50, the suction nozzle68is lowered in the negative direction of the z-axis (see (4) inFIG. 14). As a result, the suction opening71of the suction nozzle68is located right above the magazine insertion opening. In this state, the waterproof plug U sucked to the suction opening71of the suction nozzle68is dropped. Thereafter, the suction nozzle68is returned to the initial position.

As a result, the waterproof plug U is placed in the magazine insertion opening (groove76) in a direction in which the small diameter portion U1side faces the negative direction of the x-axis. Then, in Step S55, the waterproof plug U placed in the magazine insertion opening (groove76) is pushed in by the selected push-in bar78, such that the waterproof plug U is loaded into the holder20(magazine).

By repeating the above operation until a predetermined number of waterproof plugs U are loaded in the holder20, the waterproof plug magazine (for example, the waterproof plug magazines210ato210cinFIG. 1) is completed, in which the predetermined number of waterproof plugs U of the same type are loaded in the holder20in a state of being aligned in the same orientation.

The completed waterproof plug magazine is picked up from the waterproof plug supplier210. Thereafter, in order to form a next waterproof plug magazine, the component tray10is rotated such that the groove11becomes a selected groove in which the waterproof plug U of a type corresponding to the next waterproof plug magazine is placed, and the shaft73is rotated such that the bracket74(and the push-in bar78) corresponding to the type of the waterproof plug U becomes the bracket74(selected bracket, and selected push-in bar78), and the holder20corresponding to the type of the waterproof plug U is attached to the waterproof plug supplier210. Then, the above processing is performed again to complete the next waterproof plug magazine.

In the flowchart illustrated inFIG. 12, although the camera31photographs when the suction nozzle68is at the initial position, the driving unit32and the component moving unit33are not limited to being located outside the imaging range of the camera31(that is, the driving unit32and the component moving unit33do not interfere with the photographing), and the camera31may photograph when the suction nozzle68is located at a position other than the initial position. For example, in Step S45, the camera31(processing of Step S15) may photograph at a stage in which the suction nozzle68is returning to the initial position. Further, processing of Steps S20, S25, and S30may be performed following the processing of Step S15at the stage in which the suction nozzle68is returning to the initial position.

According to the wire harness manufacturing system SYS according to the embodiment of the present invention, the supply devices200(waterproof plug supplier210and housing supplier220) can supply the components (waterproof plugs and housings) to the assembly line100via the component magazine (waterproof plug magazine and housing magazine). Further, the supply devices200(each of the supply devices200) can prepare a plurality of types of component magazines different for each type of component. In other words, the supply devices200are not dedicated devices for each type of component, but general-purpose devices that can support various types of components. That is, the supply devices200and types of components are in a one-to-many relationship.

Therefore, as compared with the supply devices in the system described in the Background section, the number of devices can be reduced, and cost of the devices can be reduced. Further, since the component magazine can be used simply in accordance with the specification of the wire harness (without resetting the device), preparation cost of the assembly line100can also be reduced. In other words, by using the supply devices200and the component magazine, the assembly line100(and accordingly the entire manufacturing system SYS) can be flexibly adapted to wire harnesses having various specifications.

Therefore, the wire harness manufacturing system SYS according to the embodiment of the present invention can reduce the manufacturing cost as much as possible even when various types of components are to be supplied to the assembly line100.

As another effect, according to the wire harness manufacturing system SYS according to the embodiment of the present invention, the supply devices200are indirectly connected to the assembly line100(via a component magazine). Therefore, as compared with a case where the supply devices and the assembly line are directly connected as in the supply devices in the system, operation can be continued even if one of the devices and the assembly line100malfunctions and operation thereof is stopped. In other words, the component magazine functions as a buffer of the entire system. Therefore, stability of the manufacturing system SYS can be improved.

All components of the wire harness do not have to be magazined. A component magazine may be utilized for a part of components (for example, waterproof plugs A to C, and housings A to D), and a device as the supply device in the system may be included separately from the above supply devices200for other components (for example, terminals, and clamps).

Further, in the wire harness manufacturing system SYS according to the embodiment of the present invention, the supply devices200can continue preparing waterproof plug magazines regardless of an operation state of the assembly line100(no matter the assembly line100is operating or stopped). This makes it possible to stock the component magazines during a period in which the assembly line100is stopped due to some problems, and to prepare a future demand for the component magazines. Therefore, stability of the manufacturing system SYS can be improved.

Further, in the wire harness manufacturing system SYS according to the embodiment of the present invention, the supply devices200can prepare the component magazines while associating the number of consumed specific components on the assembly line100per unit time and the number of manufactured component magazines in which the specific components are loaded per unit time. Accordingly, the component magazines can be manufactured in accordance with the actual number of consumed components. Therefore, the supply devices200are efficiently operated in consideration of a post-process (a series of assembly steps on the assembly line100).

According to the wire harness manufacturing method according to the embodiment of the present invention, the supply devices200(waterproof plug supplier210and housing supplier220) supply components (waterproof plugs and housings) to the assembly line100via the component magazine (waterproof plug magazine and housing magazine), and prepare a plurality of types of component magazines (210ato210c,and220ato220d) for each type of component. In other words, the supply devices200are not dedicated devices different for each type of component (different for product No.), but general-purpose devices that can support various types (product No.) of components. That is, the supply devices200and the types (product No.) of components are in a one-to-many relationship via the component magazine.

Therefore, as compared with the manufacturing method in the system, the number of supply devices200can be reduced, so that installation cost of the supply devices200can be reduced. Further, since the component magazine can be used simply in accordance with the specification of the wire harness (for example, since the component magazine corresponding to the type (product No.) of the component can be simply attached to the supply devices), preparation cost of the manufacturing system SYS can be reduced without significantly resetting the supply devices200. In other words, by using the component magazine, the assembly line100(and accordingly the entire manufacturing system SYS) can be flexibly adapted to various wire harnesses.

Therefore, the wire harness manufacturing method with such a configuration can reduce the manufacturing cost of the wire harness as much as possible even when various types of components are to be supplied to the assembly line100.

As another effect, according to the wire harness manufacturing method with such a configuration, the supply devices200and the assembly line100are indirectly connected (via a component magazine). Therefore, unlike the case where both the supply devices200and the assembly line100are directly connected as in the manufacturing method in the system, operation can be continued even if one of the supply devices200and the assembly line100malfunctions and operation thereof is stopped. In other words, the component magazine functions as a buffer (buffer mechanism) of the entire system. Therefore, the wire harness manufacturing method of such a configuration can improve the stability of the entire system.

Other Embodiments

The present invention is not limited to the above embodiment, and various modifications can be adopted within the scope of the present invention. For example, the present invention is not limited to the above embodiment, but may be appropriately modified, improved or the like. Additionally, materials, shapes, sizes, numbers, arrangement places or the like of the components in the above embodiment are arbitrary and not limited as long as the present invention can be achieved.

For example, in the above embodiment, as illustrated inFIG. 8, by placing a corresponding type of waterproof plugs among a plurality of types of waterproof plugs in each of the plurality of grooves11formed in the upper surface of the component tray10, the plurality of types of waterproof plugs are placed on the component tray10separately for each type of the waterproof plug U. However, as illustrated inFIG. 15A, one large groove11continuing in the circumferential direction may be formed in the component tray10. In this case, the plurality of types of waterproof plugs may be placed on the component tray10separately for each type of the waterproof plug U by dividing the large groove11into a plurality of regions that are not continuous with each other and placing a corresponding type of waterproof plugs among a plurality of types of waterproof plugs in each of the plurality of regions in the upper surface of the component tray10. Further, the plurality of types of waterproof plugs may be placed without dividing the large groove11into regions, and the types of the waterproof plugs may be identified by the pattern matching based on a photographed image of the camera31.

Further, in the above embodiment, as illustrated inFIG. 8, the plurality of grooves11having the same shape (the same area) are formed in the upper surface of the component tray10, but as illustrated inFIGS. 15B and 15C, a plurality of grooves11having different shapes (different areas) may be formed on the upper surface of the component tray10. Accordingly, when the number of manufactured waterproof plug magazines per unit time loaded with waterproof plugs U is different for each type of the waterproof plug U, the number of waterproof plugs U that can be accommodated in the grooves11and the number of manufactured waterproof plug magazines per unit time can be associated with each other for each type of waterproof plug U. In other words, the waterproof plugs can be placed on the component tray10in accordance with the number of consumed waterproof plugs.

Further, in the above embodiment, the wire harness manufacturing system SYS is provided with a plurality of supply devices200(specifically, waterproof plug supplier210and housing supplier220) for the assembly line100, but a single supply device200(specifically, waterproof plug supplier210or housing supplier220) may be provided for the assembly line100.

Further, in the above embodiment, the bar-shaped suction nozzle68is used as a component chuck. However, as illustrated inFIG. 16, a pair of gripping arms82whose interval can be adjusted may be used as the component chuck.

Further, in the above embodiment, the driving unit32that moves the suction nozzle68along the x-y plane includes the first moving body55, the second moving body57, the first driving arm58, and the second driving arm59. However, any configuration may be adopted as the drive unit32as long as the suction nozzle68can be moved along the x-y plane.

Further, in the above embodiments, the waterproof plug magazines210ato210cand the housing magazines220ato220dare used as examples of the component magazine. However, in a case of components of a wire harness, a component magazine may be prepared by using a component other than the waterproof plug and the housing (for example, a clamp and a corrugated tube).
