Locking pin <NUM> is provided at an upper end part of body cylinder <NUM> so as to extend in a radial direction of body cylinder <NUM>. Suction nozzle <NUM> is detachably attached to mounting head <NUM> by one touch by using locking pin <NUM>. A spring (not illustrated) is built into mounting head <NUM>, and the spring applies elastic force to suction pipe <NUM> of suction nozzle <NUM> attached to mounting head <NUM>. Consequently, suction pipe <NUM> is biased in a direction extending downward from the lower end part of body cylinder <NUM> by the elastic force of the spring built into mounting head <NUM>. 2D code <NUM> is attached to an upper surface of flange portion <NUM>. 2D code <NUM> indicates an identification (ID) or the like of suction nozzle <NUM> as individual information. Instead of 2D code <NUM>, a barcode or an RF tag may be attached to the upper surface of flange portion <NUM>. However, in a case where the RF tag is attached to the upper surface of flange portion <NUM>, a reader for acquiring individual information from the RF tag is attached to transfer head (refer to <FIG>) <NUM> of nozzle management device (refer to <FIG>) <NUM> that will be described later.

Suction nozzle <NUM> communicates with positive and negative pressure supply devices (not illustrated) via a negative pressure air passage and a positive pressure air passage. Suction nozzle <NUM> picks up and holds an electronic component by using a negative pressure, and separates the held electronic component by using a positive pressure. Mounting head <NUM> has a nozzle lifting/lowering device (not illustrated) that lifts and lowers suction nozzle <NUM>. The nozzle lifting/lowering device changes a position of the electronic component held by mounting head <NUM> in the up-down direction.

Supply device <NUM> is a feeder-type supply device, and includes multiple tape feeders <NUM> as illustrated in <FIG>. Tape feeder <NUM> accommodates taped components that are wound therearound. The taped component is obtained by taping an electronic component. Tape feeder <NUM> causes a feeding device (not illustrated) to feed the taped component. Consequently, feeder-type supply device <NUM> supplies an electronic component at a supply position by feeding a taped component.

Nozzle station <NUM> includes nozzle tray <NUM>. Nozzle tray <NUM> accommodates multiple suction nozzles <NUM>. In nozzle station <NUM>, suction nozzle <NUM> attached to mounting head <NUM> and suction nozzle <NUM> accommodated in nozzle tray <NUM> are exchanged as required. 2D code <NUM> is attached to an upper surface of nozzle tray <NUM>. 2D code <NUM> indicates an identification (ID) or the like of nozzle tray <NUM> as individual information. Instead of 2D code <NUM>, a barcode or an RF tag may be attached to the upper surface of nozzle tray <NUM>. However, in a case where an RF tag is attached to the upper surface of nozzle tray <NUM>, a reader for acquiring individual information from the RF tag is attached to transfer head (refer to <FIG>) <NUM> of nozzle management device (refer to <FIG>) <NUM> that will be described later. Nozzle tray <NUM> is detachable from nozzle station <NUM>, and thus collection of suction nozzle <NUM> accommodated in nozzle tray <NUM>, provision of suction nozzle <NUM> to nozzle tray <NUM>, and the like can be performed outside mounter <NUM>.

Next, mounting work using mounter <NUM> will be described. In mounter <NUM>, with the configuration described above, mounting work can be executed on a circuit board held by conveyance device <NUM> by using mounting head <NUM>. Specifically, a circuit board is conveyed to a work position according to a command from a control device (not illustrated) of mounter <NUM>, and is held by the board holding device at that position. Tape feeder <NUM> feeds a taped component according to a command from the control device, and supplies an electronic component at a supply position. Mounting head <NUM> is moved above the supply position of the electronic component, and picks up and holds the electronic component by using suction nozzle <NUM>. Subsequently, mounting head <NUM> is moved above the circuit board, and mounts the electronic component held thereby on the circuit board.

In mounter <NUM>, as described above, an electronic component supplied by tape feeder <NUM> is picked up and held by suction nozzle <NUM>, and thus the electronic component is mounted on the circuit board. Thus, in order to perform the mounting work in mounter <NUM> by using suction nozzle <NUM> corresponding to a size, a shape, and the like of an electronic component that is a mounting target on a circuit board, it is necessary to accommodate suction nozzle scheduled to be used in the mounting work in nozzle tray <NUM> as a setup change task before the mounting work is performed. Therefore, in the nozzle management device described below, the suction nozzle scheduled to be used in the mounting work is accommodated in nozzle tray <NUM>.

Next, a configuration of the nozzle management device will be described. As illustrated in <FIG>, nozzle management device <NUM> has a generally rectangular parallelepiped shape, and is provided with door <NUM> through which nozzle tray <NUM> is stored in nozzle management device <NUM> or nozzle tray <NUM> is extracted from nozzle management device <NUM> on a front surface thereof. Touch panel <NUM> or the like that displays various pieces of information and is used to perform each operation is disposed above door <NUM>.

As illustrated in <FIG>, nozzle management device <NUM> includes management device main body <NUM>, pallet accommodation device <NUM>, nozzle transfer device <NUM>, nozzle inspection device <NUM>, nozzle cleaning device <NUM>, and nozzle drying device <NUM>. <FIG> is a perspective view illustrating a state in which an outer shell member of nozzle management device <NUM> is detached, and illustrates an internal structure of nozzle management device <NUM>.

Pallet placement shelf <NUM> is a shelf on which nozzle pallet <NUM> is placed, and multiple pallet placement shelves <NUM> are disposed to be arranged in the up-down direction inside frame <NUM>. Nozzle pallet <NUM> accommodates multiple suction nozzles <NUM>. Support arm <NUM> is moved in the up-down direction ahead of multiple pallet placement shelves <NUM> and approaches and separates from pallet placement shelves <NUM> due to an operation of an arm moving device (not illustrated). Consequently, storage of nozzle pallet <NUM> into pallet placement shelf <NUM> and extraction of nozzle pallet <NUM> from pallet placement shelf <NUM> are performed by support arm <NUM>. Nozzle pallet <NUM> extracted from pallet placement shelf <NUM> is moved above frame <NUM> due to upward movement of support arm <NUM>.

Nozzle transfer device <NUM> is a device that transfers suction nozzle <NUM> between nozzle tray <NUM> and nozzle pallet <NUM>, and is disposed in beam <NUM>. Nozzle transfer device <NUM> includes transfer head <NUM> and head moving device <NUM>. Camera <NUM> in a state of facing downward and holding chuck <NUM> that holds suction nozzle <NUM> are attached to a lower end face of transfer head <NUM>. Holding chuck <NUM> has two holding pawls (not illustrated), and by causing two holding pawls <NUM> to approach each other, suction nozzle <NUM> is held in body cylinder <NUM>, and by causing the two holding pawls to separate from each other, held suction nozzle <NUM> is released.

Head moving device <NUM> is an XYZ type moving device that moves transfer head <NUM> in the front-rear direction, the left-right direction, and the up-down direction on frame <NUM>. Three fixing stages <NUM> for setting nozzle tray <NUM> are provided on an upper surface of the front side of frame <NUM>, and suction nozzle <NUM> is transferred between nozzle tray <NUM> set on fixing stage <NUM> and nozzle pallet <NUM> supported by support arm <NUM> of pallet accommodation device <NUM>.

Nozzle inspection device <NUM> includes camera <NUM> and load cell <NUM>. Camera <NUM> is disposed on the upper surface of frame <NUM> so as to face upward, and the tip portion of suction nozzle <NUM> is inspected by using camera <NUM>. Specifically, suction nozzle <NUM> that is an inspection target is held by holding chuck <NUM>, and suction nozzle <NUM> held by holding chuck <NUM> is imaged by camera <NUM> from below. Consequently, imaging data of the tip portion of suction nozzle <NUM> is obtained, and a state of the tip portion of suction nozzle <NUM> is inspected based on the imaging data.

Load cell <NUM> is disposed near camera <NUM>, and expansion and contraction states of the tip portion of suction nozzle <NUM> are inspected by using load cell <NUM>. Specifically, suction nozzle <NUM> that is an inspection target is held by holding chuck <NUM>, and the tip portion of suction nozzle <NUM> held by holding chuck <NUM> comes into contact with load cell <NUM>. As described above, the tip portion of suction nozzle <NUM> is allowed to expand and contract, and thus the expansion and contraction states of the tip portion of suction nozzle <NUM> are inspected based on a load measured by load cell <NUM>.

Multiple discard boxes <NUM> are disposed on the upper surface of frame <NUM>, and suction nozzle <NUM> determined as being a defective nozzle through the inspection is discarded into discard box <NUM>. Suction nozzle <NUM> determined as being a normal nozzle through the above inspection is returned to nozzle tray <NUM> or nozzle pallet <NUM>.

Nozzle cleaning device <NUM> is a device that cleans and dries suction nozzle <NUM>, and is disposed near pallet accommodation device <NUM>. Nozzle cleaning device <NUM> includes cleaning/drying mechanism <NUM> and cleaning pallet moving mechanism <NUM>. Cleaning/drying mechanism <NUM> is a mechanism that cleans and dries suction nozzle <NUM> in the inside thereof. Cleaning pallet moving mechanism <NUM> is a mechanism that moves cleaning pallet <NUM> between an exposed position where cleaning pallet <NUM> is exposed (a position where cleaning pallet <NUM> is illustrated in <FIG>) and the inside of cleaning/drying mechanism <NUM>.

Nozzle drying device <NUM> is a device that dries suction nozzle <NUM>, and is disposed near cleaning pallet <NUM> located at the exposed position. In nozzle cleaning device <NUM>, although drying is also performed, moisture may remain inside suction nozzle <NUM>. In particular, in suction nozzle <NUM>, since body cylinder <NUM> and suction pipe <NUM> slide on each other, moisture may remain on a sliding surface between body cylinder <NUM> and suction pipe <NUM>. Therefore, drying chamber <NUM> that is open above is provided in nozzle drying device <NUM>, cleaned suction nozzle <NUM> is held by holding chuck <NUM>, and suction nozzle <NUM> is inserted into drying chamber <NUM>. An air blow device (not illustrated) is disposed in drying chamber <NUM>, and air is blown by the air blow device to suction nozzle <NUM> inserted into the inside of drying chamber <NUM>. Consequently, moisture on the sliding surface between body cylinder <NUM> and suction pipe <NUM> can be removed, and thus suction nozzle <NUM> can be appropriately dried.

As illustrated in <FIG>, control device <NUM> includes controller <NUM>, multiple drive circuits <NUM>, control circuit <NUM>, and memory <NUM>. Multiple drive circuits <NUM> are connected to pallet accommodation device <NUM>, nozzle transfer device <NUM>, nozzle inspection device <NUM>, nozzle cleaning device <NUM>, and nozzle drying device <NUM>. Controller <NUM> includes CPU, ROM, RAM, and the like, and is mainly a computer, and is connected to multiple drive circuits <NUM>. Consequently, operations of pallet accommodation device <NUM>, nozzle transfer device <NUM>, and the like are controlled by controller <NUM>. Controller <NUM> is connected to touch panel <NUM> via control circuit <NUM>. Consequently, any image is displayed on touch panel <NUM> by controller <NUM>. Various types of information are stored in memory <NUM>, and controller <NUM> is connected to memory <NUM>. Consequently, controller <NUM> acquires various types of information from memory <NUM>.

In nozzle management device <NUM>, with the above-described configuration, a suction nozzle (hereinafter, referred to as a "nozzle required during work") scheduled to be used in the mounting work in mounter <NUM> or the like is accommodated in nozzle tray <NUM>. Specifically, as described above, nozzle management device <NUM> is provided with nozzle inspection device <NUM>, nozzle cleaning device <NUM>, and nozzle drying device <NUM>. Thus, suction nozzles that have been inspected by nozzle inspection device <NUM> and determined as being normal, and suction nozzles that have been cleaned and dried by nozzle cleaning device <NUM> and nozzle drying device <NUM> are accommodated in nozzle pallet <NUM>. Nozzle pallet <NUM> in which the suction nozzles are accommodated is accommodated in pallet accommodation device <NUM>.

Memory <NUM> of nozzle management device <NUM> stores information regarding a suction nozzle (hereinafter, referred to as "nozzle information") to be accommodated in nozzle tray <NUM> during the setup change task, that is, a nozzle required during work in a mounter that is a target of the setup change task. The nozzle information includes the number, type, and the like of nozzles required during work. The nozzle information is naturally stored for each mounter that is a target of the setup change task, and stores information indicating the mounter (hereinafter, referred to as "mounter information") that is a target of the setup change task in correlation with the nozzle information. The mounter information is also stored in correlation with information indicating a line (hereinafter, referred to as "line information") in which a mounter indicated by the mounter information is included and information indicating a product (hereinafter, referred to as "product information") to be created by the line.

Since a size, a type, or the like of suction nozzle <NUM> to be mounted on mounting head <NUM> differs according to the type of mounting head <NUM> disposed in each of multiple mounters, nozzle tray <NUM> in which suction nozzle <NUM> is accommodated also differs according to the type of mounting head <NUM>. That is, the type of nozzle tray <NUM> differs for each mounter that is a target of the setup change task. Thus, memory <NUM> stores mounter information in correlation with information indicating nozzle tray <NUM> (hereinafter, referred to as "tray information") used in a mounter indicated by the mounter information.

In nozzle management device <NUM>, when work of accommodating a nozzle required during work in a mounter that is a target of the setup change task in nozzle tray <NUM> is executed, the name of nozzle tray <NUM> to be set in nozzle management device <NUM> is displayed on touch panel <NUM>. Specifically, setup change screen <NUM> illustrated in <FIG> is displayed on touch panel <NUM>. First selection button <NUM>, second selection button <NUM>, and third selection button <NUM> are displayed on setup change screen <NUM>. Three selection buttons <NUM>, <NUM>, and <NUM> are buttons for selecting three fixing stages <NUM> for setting nozzle tray <NUM> in nozzle management device <NUM>. First selection button <NUM> corresponds to fixing stage (hereinafter, referred to as a "left stage") <NUM> located on the leftmost side of three fixing stages <NUM>. Second selection button <NUM> corresponds to fixing stage (hereinafter, referred to as a "center stage") <NUM> located at the center of three fixing stages <NUM>. Third selection button <NUM> corresponds to fixing stage (hereinafter, referred to as a "right stage") <NUM> located on the rightmost side of three fixing stages <NUM>.

Name <NUM> of nozzle tray <NUM> (hereinafter, referred to as a "tray name") to be set in fixing stage <NUM> corresponding to each of selection buttons <NUM>, <NUM>, and <NUM> is displayed on the right of each of selection buttons <NUM>, <NUM>, and <NUM>. Together with tray name <NUM>, name <NUM> of a mounter (hereinafter, referred to as a "mounter name") in which nozzle tray <NUM> having tray name <NUM> is set is also displayed. Mounter name <NUM> is the name of a mounter indicated by mounter information stored in memory <NUM> in correlation with tray information of nozzle tray <NUM> corresponding to tray name <NUM>. Together with mounter name <NUM>, name <NUM> of a line (hereinafter, referred to as a "line name") including the mounter having mounter name <NUM> and name <NUM> of a product (hereinafter, referred to as a "product name") to be created on the line are also displayed. Line name <NUM> and product name <NUM> are names of a line and a product indicated by the line information and the product information stored in memory <NUM> in correlation with the mounter information of the mounter corresponding to mounter name <NUM>.

Specifically, "NA74A" is displayed as tray name <NUM>, "AIMEX-<NUM>" is displayed as mounter name <NUM>, "Line Name <NUM>" is displayed as line name <NUM>, and "Product1" is displayed as product name <NUM> on the right of first selection button <NUM>. "NA74A" is displayed as tray name <NUM>, "NXT-<NUM>" is displayed as mounter name <NUM>, "Line Name <NUM>" is displayed as line name <NUM>, and "Product1" is displayed as product name <NUM> on the right of second selection button <NUM>. "NA74A" is displayed as tray name <NUM>, "NXT-<NUM>" is displayed as mounter name <NUM>, "Line Name1" is displayed as line name <NUM>, and "Product1" is displayed as product name <NUM> on the right of third selection button <NUM>.

Therefore, for example, when an operator sets nozzle tray <NUM> having the name "NA74A" in left stage <NUM> corresponding to first selection button <NUM>, a nozzle required during work in a work machine having the name "AIMEX-<NUM>" is accommodated in nozzle tray <NUM> set in left stage <NUM>. For example, when the operator sets nozzle tray <NUM> having the name "NA74A" in center stage <NUM> corresponding to second selection button <NUM>, a nozzle required during work in a work machine having the name of "NXT-<NUM>" is accommodated in nozzle tray <NUM> set in center stage <NUM>. For example, when the operator sets nozzle tray <NUM> having the name of "NA74A" in right stage <NUM> corresponding to third selection button <NUM>, a nozzle required during work in a work machine having the name of "NXT-<NUM>" is accommodated in nozzle tray <NUM> set in right stage <NUM>.

The work of accommodating a nozzle required during work in nozzle tray <NUM> set in each fixing stage <NUM> is executed based on mounter information corresponding to mounter name <NUM> displayed at each of selection buttons <NUM>, <NUM>, and <NUM> corresponding to fixing stage <NUM>. Specifically, for example, in a case where nozzle tray <NUM> having the name "NA74A" is set in center stage <NUM>, since "NXT-<NUM>" is displayed as mounter name <NUM> at second selection button <NUM> corresponding to center stage <NUM>, mounter information indicating the mounter having the name "NXT-<NUM>" is specified. The nozzle information stored in memory <NUM> in correlation with the mounter information is specified. The nozzle information includes information regarding the number, the type, and the like of nozzles required during work in the mounter having the name "NXT-<NUM>". Therefore, the suction nozzle indicated by the nozzle information is accommodated in nozzle tray <NUM> set in center stage <NUM> due to operations of pallet accommodation device <NUM>, nozzle transfer device <NUM>, and the like.

As described above, in nozzle management device <NUM>, the operator sets nozzle tray <NUM> having tray name <NUM> displayed on setup change screen <NUM> in fixing stage <NUM> corresponding to selection button <NUM>, <NUM>, or <NUM> associated with tray name <NUM>, suction nozzle <NUM> associated with the setup change task is accommodated in nozzle tray <NUM>. However, when the operator executes the setup change task, nozzle tray <NUM> having tray name <NUM> displayed on setup change screen <NUM> may not be held at hand, but may have a nozzle tray having a name different from tray name <NUM>. Specifically, for example, as illustrated in <FIG>, although "NA74A" is displayed as tray name <NUM> at any of three selection buttons <NUM>, <NUM>, and <NUM> on setup change screen <NUM>, the operator may not have nozzle tray <NUM> having the name "NA74A" at hand and may have nozzle tray <NUM> having the name "ND36C". In such a case, it is wasteful of time for the operator to intentionally take the nozzle tray having the name "NA74A". Thus, it is possible to change tray name <NUM> or the like displayed in correspondence to selection buttons <NUM>, <NUM>, and <NUM>.

Specifically, for example, when the operator operates first selection button <NUM> on setup change screen <NUM>, change screen <NUM> illustrated in <FIG> is displayed on touch panel <NUM> in place of setup change screen <NUM>. Multiple mounter names <NUM> are displayed on change screen <NUM>, and tray name <NUM> is displayed in correspondence to each of multiple mounter names <NUM>. Specifically, for example, tray name <NUM> of "NA74A" is displayed in correspondence to mounter name <NUM> of "AIMEX-<NUM>", tray names <NUM> of "ND32C/ND36C" are displayed in correspondence to mounter name <NUM> of "NXT-<NUM>", and tray name <NUM> of "NA74A" is displayed in correspondence to mounter name <NUM> of "NXT-<NUM>". Tray name <NUM> is the name of a tray indicated by tray information stored in memory <NUM> in correlation with mounter information of a mounter associated with mounter name <NUM>.

That is, for example, the mounter information of mounter name <NUM> of "AIMEX-<NUM>" is stored in memory <NUM> in correlation with the tray information of tray name <NUM> of "NA74A". Thus, on change screen <NUM>, tray name <NUM> of "NA74A" is displayed in correspondence to mounter name <NUM> of "AIMEX-<NUM>". The mounter information of mounter name <NUM> of "NXT-<NUM>" is stored in memory <NUM> in correlation with the tray information of two types of tray names <NUM> of "ND32C" and "ND36C". Thus, on change screen <NUM>, two types of tray names <NUM> of "ND32C" and "ND36C" are displayed in correspondence to mounter name <NUM> of "NXT-<NUM>".

As described above, when multiple mounter names <NUM> and tray names <NUM> respectively corresponding to multiple mounter names <NUM> are displayed on change screen <NUM>, the operator operates tray name <NUM> of nozzle tray <NUM> desired to be set by the operator. In this case, since the operator has nozzle tray <NUM> of "ND36C" as described above, the operator operates tray names <NUM> of "ND32C/ND36C". Consequently, setup change screen <NUM> illustrated in <FIG> is displayed on touch panel <NUM> instead of change screen <NUM>. Tray name <NUM> selected through the operation on change screen <NUM> illustrated in <FIG> is displayed in correspondence to first selection button <NUM> on setup change screen <NUM>. That is, tray names <NUM> of "ND32C/ND36C" are displayed in correspondence to first selection button <NUM> on setup change screen <NUM> illustrated in <FIG>. Mounter name <NUM> of "NXT-<NUM>" is displayed in correspondence to tray names <NUM> of "ND32C/ND36C". This is because the tray information of "ND32C/ND36C" and the mounter information of "NXT-<NUM>" are stored in memory <NUM> in correlation with each other. Line name <NUM> of "Line Name1" and product name <NUM> of "Product1" are displayed in correspondence to mounter name <NUM> of "NXT-<NUM>". This is because the mounter information of "NXT-<NUM>", the line information of "Line Name1", and the product information of "Product1" are stored in memory <NUM> in correlation with each other.

When setup change screen <NUM> including tray names <NUM> of "ND32C/ND36C" are displayed on touch panel <NUM>, the operator sets nozzle tray <NUM> of "ND36C" in left stage <NUM> corresponding to first selection button <NUM> associated with tray names <NUM> of "ND32C/ND36C". Consequently, a nozzle required during work in the mounter "NXT-<NUM>" is accommodated in nozzle tray <NUM> of "ND36C" due to operations of pallet accommodation device <NUM>, nozzle transfer device <NUM>, and the like in accordance with the above-described procedure.

However, there is a case where the operator does not set nozzle tray <NUM> having tray name <NUM> displayed on setup change screen <NUM> in fixing stage <NUM> corresponding to selection button <NUM>, <NUM>, or <NUM> associated with tray name <NUM>. That is, when setup change screen <NUM> illustrated in <FIG> is displayed on touch panel <NUM>, the operator may erroneously set nozzle tray <NUM> of "ND36C" in center stage <NUM>. In such a case, nozzle tray <NUM> of "ND36C" may accommodate a nozzle required during work in the mounter "NXT-<NUM>", instead of a nozzle required during work in the mounter "NXT-<NUM>". Since nozzle tray <NUM> of "NA74A" is used in the mounter "NXT-<NUM>", there is concern that a nozzle required during work in the mounter "NXT-<NUM>" cannot be accommodated in nozzle tray <NUM> of "ND36C".

In view of this, when nozzle tray <NUM> is set in fixing stage <NUM>, it is checked whether nozzle tray <NUM> is set in accordance with the display of setup change screen <NUM>. Specifically, when nozzle tray <NUM> is set in fixing stage <NUM>, camera <NUM> is moved above set nozzle tray <NUM> due to an operation of head moving device <NUM> and images nozzle tray <NUM>. In this case, controller <NUM> analyzes 2D code <NUM> written on nozzle tray <NUM> based on imaging data obtained through the imaging, and acquires an ID of nozzle tray <NUM>. Controller <NUM> specifies the name of set nozzle tray <NUM> by using the acquired ID of nozzle tray <NUM>. Consequently, controller <NUM> checks whether nozzle tray <NUM> is set in accordance with the display of setup change screen <NUM>. That is, when the name of the nozzle tray set in left stage <NUM> is specified to be "ND36C", it is determined that nozzle tray <NUM> of "ND36C" is set in accordance with the display of setup change screen <NUM>. When it is determined that nozzle tray <NUM> of "ND36C" is set in accordance with the display of setup change screen <NUM>, a nozzle required during work in the mounter "NXT-<NUM>" is accommodated in nozzle tray <NUM>. Consequently, a nozzle required during work in a mounter associated with nozzle tray <NUM> can be appropriately accommodated in nozzle tray <NUM>.

As described above, the mounter information of mounter name <NUM> of "NXT-<NUM>" is stored in memory <NUM> in correlation with the tray information of the two types of tray names <NUM> of "ND32C" and "ND36C". Therefore, as illustrated in <FIG>, the two types of tray names <NUM> of "ND32C" and "ND36C" are displayed on change screen <NUM> in correspondence to mounter name <NUM> of "NXT-<NUM>". As illustrated in <FIG>, tray names <NUM> of "ND32C/ND36C" are displayed in correspondence to first selection button <NUM> on setup change screen <NUM>, and thus the operator recognizes that nozzle tray <NUM> of "ND32C" or the nozzle tray of "ND36C" can be set in left stage <NUM>.

However, it is necessary to change the display of tray name <NUM> according to the number of suction nozzles <NUM> accommodated in nozzle tray <NUM>. Specifically, nozzle tray <NUM> of "ND32C" can accommodate a maximum of <NUM> suction nozzles <NUM>, and nozzle tray <NUM> of "ND36C" can accommodate a maximum of <NUM> suction nozzles <NUM>. Therefore, when the number of nozzles required during work in the mounter "NXT-<NUM>" displayed together with the two types of tray names "ND32C" and "ND36C" is <NUM> or less, all of the nozzles required during work can be accommodated in the nozzle tray regardless of which nozzle tray "ND32C" or "ND36C" is set in the fixing stage. However, when the number of nozzles required during work in the mounter "NXT-<NUM>" exceeds <NUM>, all of the nozzles required during work cannot be accommodated in the nozzle tray in a case where the nozzle tray "ND32C" is set in the fixing stage.

Therefore, in a case where two or more types of nozzle trays <NUM> are included in the tray information stored in memory <NUM> in correlation with the mounter information, controller <NUM> specifies the nozzle information stored in memory <NUM> in correlation with the mounter information, and specifies the number of nozzles required during work based on the nozzle information. Controller <NUM> determines whether the maximum accommodation number of suction nozzles in each of the two or more types of nozzle trays <NUM> included in the tray information is equal to or larger than the number of nozzles required during work. Controller <NUM> displays, on change screen <NUM>, the name of nozzle tray <NUM> in which the maximum accommodation number of suction nozzles is equal to or larger than the number of nozzles required during work. Consequently, only tray name that can accommodate all of the nozzles required during work among the two or more types of nozzle trays <NUM> included in the tray information is displayed on change screen <NUM>.

Specifically, for example, in a case where the number of nozzles required during work is specified to be <NUM> based on the nozzle information stored in memory <NUM> in correlation with the mounter information of the mounter "NXT-<NUM>", all of the nozzles required during work can be accommodated in either nozzle tray <NUM> of "ND32C" and "ND36C". Thus, as illustrated in <FIG>, the two types of tray names <NUM> of "ND32C/ND36C" are displayed on change screen <NUM> in correspondence to mounter name <NUM> of "NXT-<NUM>". When tray name <NUM> is selected, as illustrated in <FIG>, tray names <NUM> of "ND32C/ND36C" are displayed on setup change screen <NUM> in correspondence to first selection button <NUM>.

On the other hand, for example, in a case where the number of nozzles required during work is specified to be <NUM> based on the nozzle information, all of the nozzles required during work can be accommodated in nozzle tray <NUM> of "ND36C", but not all of the nozzles required during work can be accommodated in nozzle tray <NUM> of "ND32C". Thus, as illustrated in <FIG>, tray name <NUM> of "ND36C" is displayed on change screen <NUM> in correspondence to mounter name <NUM> of "NXT-<NUM>". When tray name <NUM> is selected, as illustrated in <FIG>, tray name <NUM> of "ND36C" is displayed on setup change screen <NUM> in correspondence to first selection button <NUM>.

As described above, in a case where two or more types of nozzle trays <NUM> are included in the tray information, only tray name that can accommodate all of the nozzles required during work among the two or more types of nozzle trays <NUM> is displayed on change screen <NUM> and setup change screen <NUM>. Consequently, in a case where the operator sets nozzle tray <NUM> in fixing stage <NUM> in accordance with the display of setup change screen <NUM>, it is possible to secure appropriate work of accommodating nozzles required during work in set nozzle tray <NUM>.

Mounter <NUM> is an example of a work machine. Suction nozzle <NUM> is an example of a component holder. Nozzle tray <NUM> is an example of a tray. Nozzle management device <NUM> is an example of a holder management device. Touch panel <NUM> is an example of a display device. Nozzle transfer device <NUM> is an example of a transfer device. Fixing stage <NUM> is an example of a placement section. Controller <NUM> is an example of a determination device. Memory <NUM> is an example of a storage device.

Thus, the above-described present embodiment achieves the following effects.

In nozzle management device <NUM>, in a case where two or more types of nozzle trays are included in tray information, mounter name <NUM> of a mounter indicated by mounter information stored in memory <NUM> in correlation with the tray information and tray name <NUM> of the two or more types of nozzle trays included in the tray information are displayed in correlation with each other on setup change screen <NUM>. Consequently, since an operator can set any nozzle tray among multiple types of nozzle trays in fixing stage <NUM>, the efficiency is improved by increasing the number of options for the operator.

A maximum of <NUM> suction nozzles <NUM> can be accommodated in nozzle tray <NUM> of "ND32C", and a maximum of <NUM> suction nozzles <NUM> can be accommodated in nozzle tray <NUM> of "ND36C". In a case where the number of nozzles required during work in a mounter that is a target of the setup change task, that is, the mounter "NXT-<NUM>" is <NUM> or less, the two types of tray names <NUM> of "ND32C/ND36C" are displayed on setup change screen <NUM>. On the other hand, when the number of nozzles required during work in the mounter "NXT-<NUM>" is not <NUM> or less, tray name <NUM> of "ND32C" is not displayed on setup change screen <NUM>, and tray name <NUM> of "ND36C" is displayed. Consequently, it is possible to secure an appropriate work of accommodating nozzles required during work in nozzle tray <NUM>.

Controller <NUM> determines whether nozzle tray <NUM> set in fixing stage <NUM> is set in accordance with the display of setup change screen <NUM>. In a case where nozzle tray <NUM> is set in fixing stage <NUM> in accordance with the display of setup change screen <NUM>, work for accommodating the nozzles required during work in nozzle tray <NUM> is executed. Consequently, a nozzle required during work in a mounter associated with nozzle tray <NUM> can be appropriately accommodated in nozzle tray <NUM>.

The present disclosure is not limited to the above embodiment, and can be implemented in various forms where various modifications and improvements are made based on the knowledge of those skilled in the art, with the invention being defined by the appended claims Specifically, for example, although the present disclosure is applied to a method of displaying the name of nozzle tray <NUM> that accommodates suction nozzle <NUM> on touch panel <NUM> in the above embodiment, the present disclosure may be applied to a method of displaying the name of a tray that accommodates a component holder capable of holding a component. Specifically, as the component holder, for example, a gripper that grips a component with multiple pawls, a so-called chuck, may be employed.

In the above embodiment, the two types of nozzle trays <NUM> of "ND32C/ND36C" are stored in memory <NUM> in correlation with the mounter information as the nozzle information, but three or more types of nozzle trays <NUM> may be stored in memory <NUM> in correlation with the mounter information as the nozzle information. In such a case, three or more types of tray names <NUM> are displayed on setup change screen <NUM> and change screen <NUM>.

In the above embodiment, tray name <NUM> and mounter name <NUM> are displayed on setup change screen <NUM> or the like, but information indicating nozzle tray <NUM> and information indicating a mounter in which nozzle tray <NUM> is set may be displayed. That is, as long as information for identifying nozzle tray <NUM> or information for identifying a mounter, for example, various symbols, marks, and codes may be displayed on setup change screen <NUM> or the like.
