Patent Description:
Conventionally, there has been proposed a method of automatically installing and removing a reel on which a tape accommodating components is wound from a feeder. For example, Patent Literature <NUM> discloses that a reel detached from a feeder is received in a reel storage, or a reel delivered from the reel storage is attached to the feeder. As a result, it is assumed that an exchange operation of the reel can be performed without bothering the operator.

It can be said that promoting the automation of the exchange operation of the reel as described above can be regarded as an important issue for improving production efficiency. Here, since the number of feeders to which the reels are attached is limited and the feeders are often reused, it is necessary to first detach the reels attached to the feeders when a new reel is attached. At this time, it is necessary to appropriately process and detach the tape so that the efficiency when automatically attaching the detached reel next time is not reduced.

The main object of the present disclosure is to more appropriately detach a reel in a case where the reel is automatically installed and removed.

The invention is defined by the features of claim <NUM>.

Next, embodiments of the present disclosure will be described with reference to the drawings. <FIG> is a schematic configuration diagram of component mounting system <NUM> of the present embodiment. Component mounting system <NUM> is provided with mounting line <NUM> for mounting a component on a board, preparation line <NUM> for preparing the supply of the component, and management device <NUM> for managing the entire system, and these lines and device are installed in a factory or the like. Management device <NUM> is configured as a computer including CPU, ROM, RAM, and HDD (not illustrated), outputs information and instructions related to mounting to each device of mounting line <NUM>, and outputs information and instructions related to preparation to each device of preparation line <NUM>.

As will be described later, loop <NUM> of splicing tape <NUM> is spliced to cover tape <NUM> by the sliding of slide piece <NUM>. Tape collecting section <NUM> winds up and collects cover tape <NUM> together with splicing tape <NUM> by rotating drum shaft <NUM> to which collecting drum <NUM> is attached by the driving of the motor. In addition, for example, there is a type (second type) in which cover tape <NUM> is pulled in and collected by rotating a pair of gears while griping cover tape <NUM>, but since the configuration is well known, a description thereof will be omitted.

As illustrated in <FIG> and <FIG>, preparation line <NUM> is provided with automatic reel storage <NUM>, reel transfer robot <NUM>, reel storage location <NUM>, feeder storage <NUM>, feeder storage location <NUM>, loader <NUM>, and reel installation and removal device <NUM>. Automatic reel storage <NUM> is configured to automatically store reel <NUM> placed on cradle 22a provided in front and store reel <NUM> in the storage, or to automatically take out necessary reel <NUM> from the storage and place reel <NUM> on cradle 22a. Reel transfer robot <NUM> is provided with a vertical articulated robot arm. Reel transfer robot <NUM> transfers reel <NUM> placed in reel storage location <NUM> by the operator to cradle 22a of automatic reel storage <NUM>, or transfers reel <NUM> discharged to cradle 22a into reel installation and removal device <NUM>. AGV <NUM> or the operator returns feeder <NUM> collected from mounting line <NUM> to feeder storage location <NUM>, or takes out necessary feeder <NUM> from feeder storage location <NUM> to accommodate feeder <NUM> in feeder storage location <NUM> of mounting line <NUM>. Loader <NUM> moves front of multiple feeder storages <NUM> and front of feeder storage location <NUM>, takes out feeder <NUM> from feeder storage location <NUM> to be accommodated in feeder storage <NUM>, or takes out feeder <NUM> from feeder storage <NUM> to be accommodated in feeder storage location <NUM>. In addition, loader <NUM> transfers feeder <NUM> as an installation and removal target of reel <NUM> into reel installation and removal device <NUM>. In <FIG>, as reel storage location <NUM>, two storage locations of a storage location for used (component shortage) reel <NUM> and a storage location for new reel <NUM> are exemplified.

Reel installation and removal device <NUM> is provided with reel set base <NUM>, control device <NUM>, feeder set unit <NUM>, cover opening and closing unit <NUM>, reel transfer unit <NUM>, drum set unit <NUM>, and tape cutting unit <NUM>, which are provided on base plate <NUM>.

As illustrated in <FIG>, reel set base <NUM> is provided with base <NUM> and support pin <NUM>. Base <NUM> is a plate-like member fixed so as to be erected vertically on upper plate <NUM> of base plate <NUM>. Support pin <NUM> is a shaft-shaped member that is vertically erected from a plate surface on the right side in the drawing of base <NUM> and can be inserted into a center hole of reel <NUM>. On reel set base <NUM>, reel <NUM> is set to be installed and removed by reel transfer robot <NUM> or reel transfer unit <NUM> so that the center hole of reel <NUM> is inserted into support pin <NUM>.

In feeder set unit <NUM>, feeder <NUM> as the installation and removal target of reel <NUM> is transferred by loader <NUM> to base 40a fixed to upper plate <NUM> of base plate <NUM>. Similar to the feeder base such as mounting device <NUM>, base 40a is provided with a connector to which connector <NUM> of feeder <NUM> can be connected and a pin hole into which positioning pin <NUM> can be engaged. Therefore, control device <NUM> can communicate with the control section of feeder <NUM> attached to feeder set unit <NUM> via the connection of the connector to control tape feeding section <NUM>.

In addition, as illustrated in <FIG>, feeder set unit <NUM> is provided with guide opening and closing section <NUM>, tape drawing section <NUM>, and tape splicing section <NUM>. Although not illustrated, guide opening and closing section <NUM> is provided with a clamp that grips tape guide <NUM> from the left-right direction, an opening and closing cylinder that opens and closes the clamp, and a lifting and lowering cylinder that lifts and lowers the clamp, and lifts and lowers tape guide <NUM> by the clamp while gripping tape guide <NUM> from the left-right direction. Tape drawing section <NUM> is provided with a clip for grasping a distal end of cover tape <NUM> of reel <NUM> attached to feeder <NUM>, a moving section for moving the clip, and an actuator for opening and closing the clip via a wire connected to the clip. Tape drawing section <NUM> causes the clip to enter tape guide <NUM> in a state where tape guide <NUM> is positioned upward by guide opening and closing section <NUM>, and draws out cover tape <NUM> by grasping the distal end of cover tape <NUM> and retracting the clip.

<FIG> is a schematic configuration diagram of tape splicing section <NUM>. Tape splicing section <NUM> is provided with fixed clamp section <NUM>, moving clamp section <NUM>, and slide section <NUM>. Fixed clamp section <NUM> is provided with a pair of clamp members 47a and 47b for clamping fixing piece <NUM> of splicing tape <NUM>, and clamp cylinder 47c for performing clamping and releasing of the clamp by lifting and lowering clamp member 47a. Moving clamp section <NUM> is provided with a pair of clamp members 48a and 48b for clamping slide piece <NUM> of splicing tape <NUM>, and clamp cylinder 48c for performing clamping and releasing of the clamp by lifting and lowering clamp member 48a. Slide section <NUM> is provided with slide block 49a coupled to clamp cylinder 48c of moving clamp section <NUM>, and slide cylinder 49b that slides moving clamp section <NUM> together with slide block 49a. As illustrated in <FIG>, tape splicing section <NUM> is in a state where fixed clamp section <NUM> clamps fixed piece <NUM> and moving clamp section <NUM> clamps slide piece <NUM>. In this state, feeder set unit <NUM> causes the distal end of cover tape <NUM> drawn out by tape drawing section <NUM> to be inserted into loop <NUM>. As illustrated in <FIG>, moving clamp section <NUM> is moved to a distal end portion side of loop <NUM> by the operation of slide cylinder 49b to contract loop <NUM>, so that tape splicing section <NUM> is coupled to loop <NUM> so that cover tape <NUM> does not come off. In this manner, splicing tape <NUM> and cover tape <NUM> are spliced to each other (refer to <FIG>).

As illustrated in <FIG>, cover opening and closing unit <NUM> is provided with base 50a, support column <NUM>, pivot plate <NUM>, pickup platen <NUM>, motor <NUM>, and pulley <NUM>. Here, opening 32a (refer to <FIG>) is formed in upper plate <NUM> of base plate <NUM> on the front surface side (on the right side) of feeder set unit <NUM>. Cover opening and closing unit <NUM> is disposed below upper plate <NUM> by fixing four support columns <NUM> erected at four corners of rectangular flat base 50a to edges of opening 32a. Pivot plate <NUM> is formed in a substantially T-shape, a proximal end portion is supported by base 50a so as to be pivoted, and pickup platens <NUM> are attached to both ends of a distal end portion. Motor <NUM> is attached to base 50a, transmits a driving force via pulley <NUM>, and pivots pivot plate <NUM>. Pickup platen <NUM> is connected to a negative pressure source such as a vacuum pump via a tube, for example, and switches the presence or absence of pickup according to the presence or absence of operation of the vacuum pump. In cover opening and closing unit <NUM>, when pivot plate <NUM> is pivoted by the forward rotation of motor <NUM> until pivot plate <NUM> is substantially orthogonal to base 50a, pickup platen <NUM> abuts on reel cover <NUM> of feeder <NUM>. In this state, cover opening and closing unit <NUM> can open reel cover <NUM> so as to be accommodated in opening 32a by picking up reel cover <NUM> on pickup platen <NUM> by the operation of the vacuum pump, and then pivoting pivot plate <NUM> by rotating motor <NUM> in the reverse direction.

As illustrated in <FIG>, reel transfer unit <NUM> is provided with slide base 60a, support pin <NUM>, expanding cylinder 61a, motor <NUM>, push-in plate <NUM>, push-in cylinder 63a, chuck <NUM>, chuck cylinder 64a, guide pin <NUM>, cutter <NUM>, and cutter cylinder 66a. Slide base 60a is slidable in the X-axis direction and the Y-axis direction by slide unit <NUM> disposed on upper plate <NUM>. Slide unit <NUM> includes a well-known configuration including a slide rail laid in the sliding direction, a slider or the like that slides along the slide rail by the driving of an actuator such as a motor. Support pin <NUM> is, for example, a pin configured in a cylindrical shape by combining two semi-cylindrical members having a semicircular cross-section, and can be inserted into the center hole of reel <NUM> in a cylindrical state. In addition, when the two semi-cylindrical members move in a direction away from each other due to the operation of expanding cylinder 61a and the outer diameter is expanded, support pin <NUM> fits into the center hole of reel <NUM> and holds reel <NUM> so as not to fall off. Support pin <NUM> rotates around the shaft by transmitting the driving force of motor <NUM> via a pulley (not illustrated). Push-in plate <NUM> is a plate-like member formed so as to notch a location where support pin <NUM> is disposed, and moves along the extending direction of support pin <NUM> by the operation of push-in cylinder 63a to push and attach reel <NUM> to feeder <NUM> or the like. Chuck <NUM> holds a distal end of tape <NUM> of reel <NUM> by the operation of chuck cylinder 64a. Guide pin <NUM> guides the distal end of tape <NUM> of reel <NUM> toward chuck <NUM> side. Cutter <NUM> cuts the distal end of tape <NUM> by the operation of cutter cylinder 66a.

In addition, in reel transfer unit <NUM>, push-turning disc <NUM> illustrated in <FIG> is configured to be installed and removed from support pin <NUM>. Push-turning disc <NUM> is a disc-shaped member used when pushing and turning reel <NUM> so that support pin <NUM> in the cylindrical state can be inserted into the center hole, and multiple buffer members <NUM> are provided on the disc surface. Buffer member <NUM> is a rectangular parallelepiped-shaped member formed of, for example, urethane rubber or sponge, and is provided so that a longitudinal direction extends in a radial direction. When the outer diameter of support pin <NUM> is expanded by the operation of expanding cylinder 61a, support pin <NUM> fits into the center hole of push-turning disc <NUM> and can rotate integrally with push-turning disc <NUM>. Although not illustrated, a storage location of push-turning disc <NUM> is provided at a predetermined position of upper plate <NUM>, and reel transfer unit <NUM> can move to the storage location to attach push-turning disc <NUM> to support pin <NUM> or detach push-turning disc <NUM> from support pin <NUM>.

As illustrated in <FIG> and <FIG>, drum set unit <NUM> is provided with fixed unit <NUM> including fixed base 71a fixed so as to be erected on upper plate <NUM>, and moving unit <NUM> including slide base 81a slidable in the X-axis direction and the Y-axis direction by slide unit <NUM> disposed on upper plate <NUM>. As illustrated in <FIG>, fixed unit <NUM> is provided with Y-axis slider <NUM>, motor <NUM> (refer to <FIG>), pulley <NUM>, Z-axis slider <NUM>, motor <NUM>, pulley <NUM>, chuck <NUM>, and chuck cylinder 78a. Y-axis slider <NUM> moves a front surface (right surface in <FIG>) of fixed base 71a along the Y-axis direction (front-rear direction) by transmitting the driving force of motor <NUM> disposed on a rear surface (left surface in <FIG>) of fixed base 71a via pulley <NUM>. Z-axis slider <NUM> is provided on Y-axis slider <NUM>, and moves in the Z-axis direction (up-down direction) along the front surface of Y-axis slider <NUM> by transmitting the driving force of motor <NUM> via pulley <NUM>. Chuck <NUM> is provided on Z-axis slider <NUM>, and holds splicing tape <NUM> of collecting drum <NUM> by the operation of chuck cylinder 78a.

As illustrated in <FIG> and <FIG>, moving unit <NUM> is provided with rotary transfer disc <NUM>, motor <NUM>, drum chuck <NUM>, chuck cylinder 84a (refer to <FIG>), guide pin <NUM>, pin cylinder 85a (refer to <FIG>), tape chuck <NUM>, chuck cylinder 86a, motor <NUM>, and pulley <NUM>. Rotary transfer disc <NUM> is a disc-shaped member including support shaft 82a to which drum main body 115a of collecting drum <NUM> is attached to be installed and removed, and can rotate drum main body 115a by being rotated by the driving of motor <NUM>. In addition, rotary transfer disc <NUM> is formed with multiple long holes 82b (for example, three) extending in the radial direction at equal intervals in the circumferential direction. Drum chuck <NUM> is provided with multiple (three) chuck claws that move in long hole 82b by the operation of chuck cylinder 84a, and each chuck claw is opened and closed by the operation of chuck cylinder 84a to grasp or release collecting drum <NUM>. Multiple guide pins <NUM> are provided so as to be erected from the left surface of moving unit <NUM> to fixed unit <NUM> side. Multiple guide pins <NUM> are provided at least at positions corresponding to each of guide pins <NUM> so that a path similar to the guide path for guiding cover tape <NUM> to collecting drum <NUM> can be formed in feeder <NUM>. Therefore, by moving chuck <NUM> holding a distal end of splicing tape <NUM> along the path formed by guide pin <NUM> by Y-axis slider <NUM> and Z-axis slider <NUM>, drum set unit <NUM> can guide guide pin <NUM> so that splicing tape <NUM> crawls on guide pin <NUM> to form a path similar to the guide path in feeder <NUM>. In addition, a part of guide pin <NUM> is moved by the driving of pin cylinder 85a, so that splicing tape <NUM> can be held by guide pins <NUM>. Tape chuck <NUM> can hold the distal end of splicing tape <NUM> forming the guide path by the operation of chuck cylinder 86a, and the distal end position of held splicing tape <NUM> can be adjusted by transmitting the driving force of motor <NUM> via pulley <NUM> and moving in the Y-axis direction.

As illustrated in <FIG> and <FIG>, tape cutting unit <NUM> is provided with base 90a, cutting base <NUM>, tape feeding section <NUM>, first tape cutter <NUM>, second tape cutter <NUM>, third tape cutter <NUM>, and slider <NUM>. Tape feeding section <NUM> is provided with sprocket <NUM> having a protrusion formed on an outer periphery for engaging with an engagement hole of tape <NUM>, and motor <NUM> for driving sprocket <NUM>. In a state where tape <NUM> fed from reel <NUM> of reel transfer unit <NUM> with respect to the right end of cutting base <NUM> is engaged with sprocket <NUM>, tape feeding section <NUM> rotates sprocket <NUM> by the forward rotation of motor <NUM> to feed tape <NUM> toward the cutting position.

First tape cutter <NUM> has a scissor-shaped cutting blade disposed in a direction orthogonal to the feeding direction of tape <NUM>, and is operated by the driving of cutter cylinder 95a to cut tape <NUM>. In second tape cutter <NUM>, a cutting blade is disposed obliquely with respect to the feeding direction of tape <NUM>, and the right side of the distal end of tape <NUM> is cut in a tapered manner by the driving of cutter cylinder 96a. In third tape cutter <NUM>, a cutting blade is disposed obliquely with respect to the feeding direction of tape <NUM>, and the left side of the distal end of tape <NUM> is cut in a tapered manner by the driving of cutter cylinder 97a. Third tape cutter <NUM> is provided on slider <NUM> that slides in the X-axis direction (left-right direction) above cutting base <NUM>, and is movable in the left-right direction. Therefore, by adjusting the position of third tape cutter <NUM> in accordance with the width of tape <NUM>, tape cutting unit <NUM> can cut in a tapered manner the left side of the distal end of tape <NUM> fed out with reference to the right end of cutting base <NUM>. By cutting the distal end of tape <NUM> (cover tape <NUM>) in a tapered manner, it is possible to prevent the distal end from being caught when inserting tape <NUM> into loop <NUM>, so that tape <NUM> can be smoothly inserted (refer to <FIG>).

Control device <NUM> is provided with CPU 39a, ROM 39b, RAM 39c, and the like. Status information and the like are inputted from each unit of reel installation and removal device <NUM>, and status information on reel transfer robot <NUM> and loader <NUM>, instruction for installation and removal of reel <NUM>, and the like are inputted from management device <NUM> to control device <NUM>. Control device <NUM> outputs a control signal to each unit of reel installation and removal device <NUM> based on the information and the instruction for installation and removal to install and remove reel <NUM> to and from feeder <NUM> set in feeder set unit <NUM>. In addition to these configurations, reel installation and removal device <NUM> may be provided with a camera capable of capturing an image of label <NUM> of reel <NUM> attached to feeder <NUM>. In addition, when reel <NUM> is detached from feeder <NUM> set in feeder set unit <NUM>, a temporary fastening portion for fastening tape <NUM> with a temporary fastening tape may be provided, or a peeling portion for peeling the temporary fastening tape when reel <NUM> is attached may be provided.

The following is a description of the operation of reel installation and removal device <NUM> configured in this manner. <FIG> is a flowchart illustrating an example of a reel detachment process. The process is executed by control device <NUM> in a case where feeder <NUM> as a detachment target from reel <NUM> is set in feeder set unit <NUM>. First, control device <NUM> causes cover opening and closing unit <NUM> so as to open reel cover <NUM> (S100). As described above, since cover opening and closing unit <NUM> holds reel cover <NUM> in opening 32a, reel cover <NUM> in the opened state can be prevented from interfering with the movement or operation of other units. Next, control device <NUM> controls slide unit <NUM> so that reel transfer unit <NUM> moves to feeder set unit <NUM> (S105). Reel transfer unit <NUM> is in a state where push-turning disc <NUM> is attached to support pin <NUM>. Subsequently, control device <NUM> causes feeder <NUM> and reel transfer unit <NUM> set in feeder set unit <NUM> so as to reserve a predetermined length to rewind tape <NUM> (S110). In S110, control device <NUM> causes tape feeding section <NUM> of feeder <NUM> so as to rotate in the reverse direction, and controls reel transfer unit <NUM> so as to push and turn reel <NUM> in the reverse rotation direction by push-turning disc <NUM>. When S110 is ended, control device <NUM> causes reel transfer unit <NUM> so as to detach push-turning disc <NUM> from support pin <NUM>.

Here, in first type feeder <NUM> using collecting drum <NUM>, since a distal end of cover tape <NUM> is spliced to splicing tape <NUM> when reel <NUM> is attached (refer to <FIG>) next time, the length of tape <NUM> (cover tape <NUM>) that needs to be reserved when reel <NUM> is detached may be shortened. On the other hand, in second type feeder <NUM> or the like using a take-up gear, it is necessary to reserve a length necessary for cover tape <NUM> to reach the take-up gear when reel <NUM> is attached next time. In the present embodiment, in S110, a predetermined length is reserved according to the type requiring the longest length (here, second type) so that reel <NUM> can handle any type of feeder <NUM> to be attached next time.

When tape <NUM> is rewound, control device <NUM> causes reel transfer unit <NUM> so as to cut tape <NUM> to detach reel <NUM> from feeder <NUM> (S115). Reel transfer unit <NUM> cuts tape <NUM> by causing cutter <NUM> to enter feeder <NUM>. Next, control device <NUM> controls slide unit <NUM> so that reel transfer unit <NUM> moves to reel set base <NUM> (S120), and causes reel transfer unit <NUM> so as to set detached reel <NUM> on reel set base <NUM> (S125). When there are remaining components on tape <NUM>, reel <NUM> set on reel set base <NUM> is transferred to cradle 22a of automatic reel storage <NUM> by reel transfer robot <NUM>. In addition, reel <NUM> having no remaining components is transferred to used reel storage location <NUM> by reel transfer robot <NUM>, or is discharged from a discharge port (not illustrated) formed in upper plate <NUM>.

Subsequently, control device <NUM> determines whether feeder <NUM> is the first type using collecting drum <NUM> (S130). When it is determined that the type is the first type, control device <NUM> controls slide unit <NUM> so that moving unit <NUM> of drum set unit <NUM> moves to feeder set unit <NUM> (S135). Next, control device <NUM> causes drum chuck <NUM> of moving unit <NUM> so as to detach collecting drum <NUM> from feeder <NUM> (S140). Control device <NUM> controls slide unit <NUM> so that moving unit <NUM> moves to a standby position in front of fixed unit <NUM> or the like (S145). When it is determined in S130 that the type is not the first type, control device <NUM> skips S135 to S145. Collecting drum <NUM> detached in S140 is assumed to be collected in a dust box or the like from a discharge port (not illustrated) formed in upper plate <NUM> until moving unit <NUM> moves to the standby position. The operator may detach cover tape <NUM> from collecting drum <NUM> collected in the dust box, discard cover tape <NUM>, and set collecting drum <NUM> at a predetermined location where moving unit <NUM> of drum set unit <NUM> can receive collecting drum <NUM>.

Control device <NUM> determines whether reel <NUM> is attached to feeder <NUM> set in feeder set unit <NUM> (S150). When it is determined that reel <NUM> is not to be attached, control device <NUM> causes cover opening and closing unit <NUM> so as to close reel cover <NUM> (S155), and ends the reel detachment process. On the other hand, when it is determined that reel <NUM> is attached, control device <NUM> skips S155, and ends the reel detachment process while maintaining reel cover <NUM> open.

Next, an attachment process of the reel will be described. <FIG> is a flowchart illustrating an example of the reel attachment process. The process is executed by control device <NUM> in a case where feeder <NUM> as an attachment target to reel <NUM> is set in feeder set unit <NUM>, for example, in a case where the reel detachment process in <FIG> ends with reel cover <NUM> open, or the like. First, control device <NUM> controls slide unit <NUM> so that reel transfer unit <NUM> moves to reel set base <NUM> (S200). Reel transfer unit <NUM> is in a state where push-turning disc <NUM> is detached from support pin <NUM>. Next, control device <NUM> causes reel transfer unit <NUM> to receive reel <NUM> set on reel set base <NUM> (S205). Subsequently, control device <NUM> controls slide unit <NUM> so that reel transfer unit <NUM> moves to tape cutting unit <NUM> (S210). Reel transfer unit <NUM> and tape cutting unit <NUM> are controlled so that a necessary amount of tape <NUM> is fed from reel <NUM> to cut the distal end of tape <NUM> into a necessary shape (S215). When feeder <NUM> as an attachment target is the first type using collecting drum <NUM>, control device <NUM> causes tape cutting unit <NUM> so as to cut in a tapered manner the distal end of tape <NUM> in order to be easily inserted into loop <NUM> as described above. In addition, when such tapered cutting is not necessary, control device <NUM> causes tape cutting unit <NUM> so as to cut only in a direction orthogonal to the longitudinal direction of tape <NUM>, for example. The distal ends of all tapes <NUM> may be cut in a tapered manner. When tape <NUM> is cut by tape cutting unit <NUM>, control device <NUM> causes reel transfer unit <NUM> so as to rewind tape <NUM> and hold the distal end of tape <NUM> by chuck <NUM>.

Subsequently, control device <NUM> controls slide unit <NUM> so that reel transfer unit <NUM> moves to feeder set unit <NUM> (S220). In a case where reel cover <NUM> of feeder <NUM> set in feeder set unit <NUM> is in the closed state, control device <NUM> causes cover opening and closing unit <NUM> so as to open reel cover <NUM> before S220. Next, control device <NUM> causes reel transfer unit <NUM> and slide unit <NUM> so as to attach reel <NUM> to feeder <NUM> set in feeder set unit <NUM>, and move to a predetermined standby position (S225).

Control device <NUM> determines whether feeder <NUM> is the required first type of collecting drum <NUM> (S230). When it is determined that the tape is the first type, control device <NUM> causes drum set unit <NUM> so as to cause splicing tape <NUM> to crawl along the path formed by guide pins <NUM>, to hold splicing tape <NUM> by guide pins <NUM>, and to grasp and hold the distal end of splicing tape <NUM> by tape chuck <NUM> (S235). Next, control device <NUM> controls slide unit <NUM> so that moving unit <NUM> moves to feeder set unit <NUM> (S240). Subsequently, control device <NUM> causes drum set unit <NUM> so as to attach collecting drum <NUM> and splicing tape <NUM> to feeder <NUM> of feeder set unit <NUM> (S245). Control device <NUM> attaches splicing tape <NUM> crawled along the path formed by guide pin <NUM> so as to pass splicing tape <NUM> to each guide pin <NUM> of feeder <NUM> in that state, and then causes drum set unit <NUM> so as to release the holding of splicing tape <NUM> by guide pins <NUM>. As a result, splicing tape <NUM> can be attached along the guide path of feeder <NUM>. In addition, when it is determined in step S230 that collecting drum <NUM> is not a necessary type, control device <NUM> skips S235 to S245. Control device <NUM> may execute S235 to S245 before S200 to S215, or may execute S235 to S245 in parallel with S200 to S215.

Control device <NUM> causes feeder set unit <NUM> so as to perform a distal end process of tape <NUM> (S250). For example, when feeder <NUM> is the first type, control device <NUM> causes feeder set unit <NUM> so as to draw cover tape <NUM> and splice cover tape <NUM> to splicing tape <NUM>. In addition, when feeder <NUM> is the second type, control device <NUM> causes feeder set unit <NUM> so as to draw cover tape <NUM> and feed to the guide path. When reel <NUM> is attached in this manner, control device <NUM> causes cover opening and closing unit <NUM> so as to close reel cover <NUM> (S255), and ends the reel attachment process. In a case where reel installation and removal device <NUM> is provided with a camera capable of capturing an image of label <NUM> of reel <NUM>, control device <NUM> may cause the camera to capture an image of label <NUM> before closing reel cover <NUM>, and may perform image processing on the captured image to recognize the information on label <NUM>. Based on the recognized information, control device <NUM> may confirm whether correct reel <NUM> is attached, register the attachment in association with feeder <NUM>, or transmit the recognized information to management device <NUM> together with the notification that the attachment of reel <NUM> is completed.

Here, correspondences between the constituent elements of the present embodiment and constituent elements of the present disclosure will be clarified. Reel installation and removal device <NUM> of the present embodiment corresponds to the reel installation and removal device of the present disclosure, feeder set unit <NUM> corresponds to a feeder set unit, reel transfer unit <NUM> corresponds to a reel transfer unit, chuck <NUM> corresponds to a holding section, cutter <NUM> corresponds to a cutting section, and control device <NUM> corresponds to a control device. Collecting drum <NUM> corresponds to a drum-shaped collecting section. Guide pin <NUM> corresponds to a path forming section, chuck <NUM>, Y-axis slider <NUM>, and Z-axis slider <NUM> correspond to a guide section, drum set unit <NUM> corresponds to a collecting section set unit, and tape splicing section <NUM> corresponds to a splicing section. Reel cover <NUM> corresponds to an opening and closing cover, and cover opening and closing unit <NUM> corresponds to a cover opening and closing unit. In addition, preparation line <NUM> corresponds to a feeder preparation system, feeder storage <NUM> corresponds to a feeder storage section, loader <NUM> corresponds to a feeder preparation device, reel set base <NUM> corresponds to a reel set base, and reel transfer robot <NUM> corresponds to a reel preparation device.

In reel installation and removal device <NUM> described above, since feeder <NUM> is set on feeder set unit <NUM> so that tape feeding section <NUM> (feeding section) can be driven, tape <NUM> can be quickly rewound when reel <NUM> is detached. In addition, reel transfer unit <NUM> rotates push-turning disc <NUM>, so that tape <NUM> can be appropriately rewound on reel <NUM>. In addition, tape <NUM> is rewound to a portion to which the component has been supplied and cut, so that it is possible to prevent the component from falling off by the distal end process of tape <NUM> when reel <NUM> is attached next time. As a result, reel <NUM> can be more appropriately detached.

In addition, since tape <NUM> (cover tape <NUM>) is rewound so as to reserve a predetermined length, it is possible to suppress the time required for the process to collect cover tape <NUM> when reel <NUM> is attached next time. In addition, since splicing tape <NUM> is attached to feeder <NUM> after being along disposed the guide path of cover tape <NUM>, drum set unit <NUM> can efficiently attach collecting drum <NUM>. In addition, since the detachment and attachment of reel <NUM> are performed by a common device, reel installation and removal device <NUM> can be configured to be more compact than those performed by separate devices. In addition, since reel cover <NUM> in the opened state is held at a position that does not interfere with the movement of other units, cover opening and closing unit <NUM> can further efficiently detach and attach the reel.

It is needless to say that the invention is limited by the appended claims.

For example, in the above embodiment, tape <NUM> is rewound by reserving a predetermined length when reel <NUM> is detached; however, the configuration is not limited to this, and, for example, an extension tape having a necessary length may be added to the distal end of tape <NUM> when reel <NUM> is attached next time.

In the above embodiment, both chuck <NUM> and cutter <NUM> are provided in reel transfer unit <NUM>; however, the configuration is not limited to this, either or both may be provided in a place other than reel transfer unit <NUM>, and, for example, may be provided in feeder set unit <NUM>.

In the above embodiment, first type feeder <NUM> to be collected by collecting drum <NUM> is exemplified, and drum set unit <NUM> that installs and removes collecting drum <NUM> and forms the path of splicing tape <NUM> is provided; however, the configuration is not limited to this. For example, reel transfer unit <NUM> may detach collecting drum <NUM> together with reel <NUM> instead of drum set unit <NUM>. In addition, the path formation of splicing tape <NUM> may be performed by feeder set unit <NUM> or reel transfer unit <NUM> after collecting drum <NUM> is attached to feeder <NUM>. In such a case or in a case where first type feeder <NUM> is not handled, drum set unit <NUM> need not be provided.

In the above embodiment, an example in which reel cover <NUM> is attached to the lower edge of feeder <NUM> in an openable and closable manner is exemplified; however, the configuration is not limited to this, reel cover <NUM> may be attached to feeder <NUM> in an openable and closable manner, and the opening and closing direction may be the left-right direction.

In the above embodiment, feeder <NUM> is set such that feeder set unit <NUM> can drive tape feeding section <NUM>; however, the configuration is not limited to this, and feeder <NUM> may be set such that tape feeding section <NUM> cannot be driven. In addition, although reel transfer unit <NUM> is configured to push and turn reel <NUM> by using push-turning disc <NUM>, reel <NUM> may be rotated by a method other than push-turning. Alternatively, reel transfer unit <NUM> may not rotate reel <NUM> (may not include a rotation section). In addition, control device <NUM> may be driven at least chuck <NUM> (holding section) and cutter <NUM> (cutting section) so as to hold and cut tape <NUM> at the portion to which the component has been supplied, in a state where feeder <NUM> to which reel <NUM> is attached is set in feeder set unit <NUM>.

In the above embodiment, in addition to reel installation and removal device <NUM>, preparation line <NUM> (preparation system) including loader <NUM> for setting feeder <NUM> in feeder set unit <NUM>, reel transfer robot <NUM> for setting reel <NUM> in reel set base <NUM>, and the like is exemplified; however, the configuration is not limited to this. Reel installation and removal device <NUM> is individually disposed, and the set of feeder <NUM> and the set of reel <NUM> may be performed by another device such as AGV, or may be performed by an operator. In addition, the disposition of each unit of reel installation and removal device <NUM> and the function of each unit are examples, and reel installation and removal device <NUM> as a whole may be configured to automatically install and remove reel <NUM> with respect to feeder <NUM>.

Here, the reel installation and removal device of the present disclosure may be configured as follows. In the reel installation and removal device of the present disclosure, the tape may include a bottom tape accommodating the component and a cover tape covering the component, and may be capable of supplying the component by peeling off the cover tape, as the feeder, multiple types of feeders including a type having a drum-shaped collecting section collecting the cover tape while winding the cover tape together with a splicing tape to which a distal end is spliced to the cover tape and a type in which the cover tape is pulled and collected to the collecting section different from the drum shape may be provided, and the control device may drive the feeding section and the rotation section to rewind the cover tape by reserving a length adaptable for any type when the reel is attached to the feeder next time in the detachment control. Accordingly, it is possible to appropriately detach the reel in consideration of the case where the reel is attached next time. Therefore, it is possible to efficiently perform the automatic attachment of the reel while suppressing the time required for the process to collect the cover tape when the reel is attached next time.

In the reel installation and removal device according to the present disclosure, the feeder may be provided with a guide path guiding the cover tape to the collecting section, the device further may include a collecting section set unit configured to be moved relative to the feeder set unit, having a path forming section forming a path along the guide path and a guide section guiding the splicing tape to crawl on the path forming section, and configured to transfer the drum-shaped collecting section, the feeder set unit may include a splicing section configured to splice a distal end of the splicing tape and a distal end of the peeled cover tape, and the control device may cause the collecting section set unit so as to attach the splicing tape and the collecting section to the feeder set in the feeder set unit, and may control the feeder set unit so that the splicing section splices the distal end of the splicing tape and the distal end of the cover tape, after the splicing tape is crawled on the path forming section in advance in the collecting section set unit. Accordingly, in a feeder of a type using the drum-shaped collecting section, it is possible to efficiently attach the reel and the collecting section.

In the reel installation and removal device of the present disclosure, the control device may execute an attachment control of attaching the reel to the feeder in a state where the feeder from which the reel is detached is set in the feeder set unit, driving the holding section and the rotation section so that a distal end of the tape is fed from the reel to the feeding section, and controlling the feeder set unit and the reel transfer unit so that the feeding section is driven until the distal end of the tape reaches a predetermined position. Accordingly, since the detachment and the attachment of the reels can be performed by a common installation and removal device, the installation and removal device can be configured to be compact.

In the reel installation and removal device of the present disclosure, the feeder may include an opening and closing cover that exposes the reel in an opened state to be installed and removed, the device further includes a cover opening and closing unit configured to open and close the opening and closing cover of the feeder set in the feeder set unit, and to hold the opening and closing cover in the opened state at a position not interfering with a relative movement of other units to the feeder set unit. Accordingly, the installation and removal of the reel can be further efficiently performed.

Furthermore, another reel installation and removal device of the present disclosure is a reel installation and removal device that installs and removes a reel on which a tape accommodating a component is wound to and from a feeder which feeds the tape by driving of a feeding section and supplies the component, the device including a feeder set unit on which the feeder is set, a holding section configured to hold the tape of the reel mounted on the feeder, a cutting section configured to cut the tape, and a control device configured to drive the holding section and the cutting section so that the tape is held and cut at a portion to which the component has been supplied, in a state where the feeder to which the reel is attached is set in the feeder set unit. Even in this manner, since it is possible to prevent the component from being affected by the distal end process of the tape when the reel is attached next time by cutting the tape at the portion to which the component has been supplied, it is possible to more appropriately detach the reel in a case where the installation and removal of the reel is automatically performed.

In addition, a feeder preparation system of the present disclosure includes any of the reel installation and removal devices described above, a feeder preparation device configured to transfer the feeder between a feeder storage section storing multiple feeders and the feeder set unit, and to prepare the feeder as an installation and removal target of the reel, a reel set base on which the reel is set so that the reel transfer unit is transferred, and a reel preparation device configured to transfer the reel between a reel storage section storing multiple reels and the reel set base, and to prepare the reel as an installation and removal target to the feeder.

In the feeder preparation system of the present disclosure, since the reel is automatically installed and removed to and from the feeder by any of the reel installation and removal devices described above, it is possible to more appropriately detach the reel. In addition, since the preparation of the feeder and the preparation of the reel can also be automatically performed, the automatic installation and removal of the reel can be further efficiently performed.

The present disclosure can be used in the manufacturing industry of component mounting systems and the like.
