Abstract

The number-of-sheets determining process is executed by using a substrate (B3) as an execution object, wherein all trays (P) required for the production cannot be accommodated in a tray rack (61) through one-time production change adjusting operation. Specifically, the ratios of the number of trays (P) required for producing the target substrate (B3) to the types (Cd, Ce) of components are determined based on the component supply information (Is) and the component use information (Iu). The number of trays corresponding to each type (Cd, Ce) of the components accommodated in the tray rack (61) by a setup operation for producing the substrate (B3) to be executed is determined according to the ratio. Thus, elements of various types (Cd, Ce) used in production of a substrate (B3) to be subjected to sheet number determination processing are stored in the tray rack (61) in numbers corresponding to the ratios of the elements used. Thus, the elements of the respective kinds (Cd, Ce) are fed out from the element supply section (5) at substantially the same timing as the substrate production is performed. This can reduce the frequency of setup work and reduce the burden on the operator.

Problems to be solved by the invention

However, the number of trays that can be accommodated in the component supply apparatus is limited. Therefore, there is a case where all the components used in the substrate production cannot be accommodated in the component supply apparatus by one setup adjustment operation. In such a case, the operator needs to perform the setup adjustment work a plurality of times. However, if the setup change adjustment work is frequently performed, the burden on the operator increases. In contrast, in patent document 1, a situation in which a plurality of setup operations are required is not particularly considered.

Means for solving the problems

The invention relates to a setup change adjustment support device, which comprises a calculation unit and a storage unit, wherein the calculation unit calculates an execution mode of a setup change adjustment operation for an operator to execute a setup change adjustment operation for accommodating a tray in a tray rack on a component supply device, the component supply device comprises a tray rack capable of accommodating a plurality of trays on which components are placed, and supplies the components by moving the tray from the tray rack to a component supply position, the storage unit stores component supply information and component use information, the component supply information is information indicating the number of components that can be supplied from the tray for each type of the components, the component use information is information indicating the number of components used in a substrate production plan for mounting the components supplied from the component supply device on a substrate for each type of the components, and the calculation unit can execute a number determination process by using as an execution target all substrates for which the trays required for the production cannot be accommodated in the tray rack by one setup change adjustment operation, in the number-of-sheets determination process, the ratio of the number of trays required for producing the substrate to be executed to each type of component is obtained based on the component supply information and the component use information, and the number of trays corresponding to each type of component, which are accommodated in the tray rack for producing the substrate to be executed by the replacement adjustment work, is determined according to the ratio.

The setup change adjustment support method according to the present invention includes the steps of: acquiring component supply information and component use information for calculating an execution mode of an operator performing a setup operation of storing a tray in a tray rack on a component supply device, the component supply device being provided with the tray rack capable of storing a plurality of trays on which components are placed and supplying the components by moving the trays from the tray rack to a component supply position, the component supply information being information indicating the number of components that can be supplied from the tray for each type of the components, the component use information being information indicating the number of components used in a substrate production plan for mounting the components supplied from the component supply device on a substrate for each type of the components; and performing a number-of-sheets determination process on the substrate, as an execution target, in which all of the trays necessary for the production cannot be accommodated in the tray rack by one setup adjustment operation, wherein in the number-of-sheets determination process, a ratio of the number of the trays necessary for the production of the substrate to be the execution target to each type of the component is obtained based on the component supply information and the component use information, and the number of the trays necessary for the production of the substrate to be the execution target to each type of the component accommodated in the tray rack by the setup adjustment operation is determined according to the ratio.

The setup assist program according to the present invention causes a computer to execute the following steps: acquiring component supply information and component use information for calculating an execution mode of an operator performing a setup operation of storing a tray in a tray rack on a component supply device, the component supply device being provided with the tray rack capable of storing a plurality of trays on which components are placed and supplying the components by moving the trays from the tray rack to a component supply position, the component supply information being information indicating the number of components that can be supplied from the tray for each type of the components, the component use information being information indicating the number of components used in a substrate production plan for mounting the components supplied from the component supply device on a substrate for each type of the components; and performing a number-of-sheets determination process on the substrate, as an execution target, in which all of the trays necessary for the production cannot be accommodated in the tray rack by one setup adjustment operation, wherein in the number-of-sheets determination process, a ratio of the number of the trays necessary for the production of the substrate to be the execution target to each type of the component is obtained based on the component supply information and the component use information, and the number of the trays necessary for the production of the substrate to be the execution target to each type of the component accommodated in the tray rack by the setup adjustment operation is determined according to the ratio.

The recording medium according to the present invention records the setup assist program so as to be readable by a computer.

In the present invention (setup assist device, setup assist method, setup assist program, and recording medium) configured as described above, the sheet count determination process is executed with all trays necessary for the production being unable to be accommodated in the tray rack by one setup operation as targets. Specifically, in the number-of-sheets determination process, the ratio of the number of sheets of the tray required for producing the target substrate to each type of component is determined based on the component supply information and the component use information. Then, the number of pallets corresponding to each type of component accommodated in the pallet rack by a setup change operation for producing the substrate to be executed is determined according to the ratio. According to the present invention, the various types of elements used in the production of the substrate as the execution target of the sheet count determination process are accommodated in the tray rack in the number corresponding to the ratio of the elements used. Thus, the various kinds of components are supplied from the component supply apparatus at substantially the same timing as the substrate production is performed. Therefore, the frequency of the setup work can be suppressed as compared with the case where the setup work is performed each time the various types of elements are supplied at random timing. Thus, the frequency of setup adjustment work can be suppressed, and the burden on the operator can be reduced.

In addition, the setup change adjustment support device may be configured such that the substrate production plan indicates a plan for producing a single type of the plurality of substrates, and the calculation unit may execute the number-of-sheets determination process with the single type of the plurality of substrates as an execution target when all the trays necessary for producing the single type of the plurality of substrates cannot be accommodated in the tray rack by one setup change operation. In this way, even when a plurality of substrates of a single type are produced, by executing the number-of-sheets determining process, the respective types of elements used in the production of the substrates to be executed are stored in the tray rack in the number corresponding to the ratio of the elements used. As a result, the frequency of setup adjustment work can be suppressed, and the burden on the operator can be reduced.

In addition, the setup changeover support device may be configured such that the substrate production plan indicates a plan for producing a predetermined number of sheets of each of the plurality of types of substrates, and the calculation unit may execute the sheet number determination process with all of the plurality of types of substrates as execution targets when all of the trays necessary for producing the plurality of types of substrates cannot be accommodated in the tray rack by one setup changeover operation. In this way, even when a predetermined number of substrates are produced from a plurality of types of substrates, the number of elements of each type used for producing the substrates to be executed are stored in the tray rack in the number corresponding to the ratio of the elements used. As a result, the frequency of setup adjustment work can be suppressed, and the burden on the operator can be reduced.

The setup change adjustment support device may be configured such that the substrate production plan indicates a plan for producing a predetermined number of sheets of substrates in a predetermined production order, the calculation unit executes a tray determination process for determining trays to be stored in the tray rack by a plurality of setup change adjustment operations based on the production order, and when all trays necessary for the production cannot be stored in the tray rack by one setup change operation, the substrate production plan executes the sheet number determination process with the type of substrate determined in the tray determination process as an execution target. In this way, even when a plurality of types of substrates are produced in sequence, by executing the number-of-sheets determining process, the respective types of elements used for production of the substrates to be executed are stored in the tray rack in the number corresponding to the ratio of the elements used. As a result, the frequency of setup adjustment work can be suppressed, and the burden on the operator can be reduced.

In the setup change adjustment support device, the number of trays that can be stored in the tray rack can be changed according to the thickness of the component mounted on the tray, and in the number-of-sheets determination process, the number of trays that can be stored in the tray rack according to the number of the components in the tray rack is determined by one setup change adjustment operation. This configuration enables the tray having the appropriate number of sheets to be stored in accordance with the change in the number of sheets that can be stored in the tray rack by each setup-change operation, which contributes to efficient setup-change operations.

Effects of the invention

According to the present invention, it is possible to suppress the frequency of a setup adjustment operation for housing a tray on which components are mounted in a component supply device used for producing a substrate on which the components are mounted, thereby reducing the burden on an operator.

Detailed Description

Fig. 1 is a plan view schematically showing an example of an application target of a setup operation by the setup assist device according to the present invention. Fig. 1 and the following drawings appropriately show a three-dimensional orthogonal coordinate system showing an X direction (substrate transfer direction), a Y direction (front-back direction), and a Z direction (vertical direction). The surface mounting apparatus 1 has a schematic configuration in which supplied components from

component supply units

4 and 5 are mounted on a substrate B carried in by a substrate transport mechanism 2 by a head unit 3.

In the surface mounting apparatus 1, a substrate conveyance mechanism 2 that conveys a substrate B in a substrate conveyance direction X is disposed on a base 11. The substrate transfer mechanism 2 has a structure in which two conveyors 21 extending in the substrate transfer direction X are arranged at intervals in the width direction Y. The two conveyors 21 convey the substrate B carried in from the upstream side (-X side) in the substrate conveying direction X toward the downstream side (+ X side) in the substrate conveying direction X, and stop the substrate B at a predetermined mounting work position (position of the substrate B in fig. 1). The substrate B stopped at the mounting work position is fixed to the mounting work position by a holding mechanism, not shown. Further, the two conveyors 21 carry out the substrate B, which has received the component mounting at the mounting work position, from the mounting work position toward the downstream side (+ X side) in the substrate conveying direction X.

Component mounting to the substrate B fixed at the mounting work position is performed by the head unit 3 transferring the components supplied from the

component supply units

4 and 5 to the substrate B. The head unit 3 has a configuration in which a plurality of mounting heads 31 having suction nozzles at their tips are arranged along the substrate transfer direction X. The head unit 3 is moved in the X direction and the Y direction above the conveyor 21, picks up the supplied components from the

component supply units

4 and 5 by the suction nozzles, and transfers the picked components to the substrate B at the mounting work position. Such movement of the head unit 3 is performed by the following structure.

That is, the base 11 is provided with a Y-axis fixed rail 71 extending in the Y direction and a Y-axis ball screw shaft 73 rotated by a Y-axis servomotor 72. The head unit support member 74 is movably supported by the Y-axis fixed rail 71, and a nut portion 75 provided on the head unit support member 74 is screwed to the Y-axis ball screw shaft 73. The head unit support member 74 is provided with an X-axis guide member (not shown) extending in the X direction and an X-axis ball screw shaft 77 rotated by an X-axis servo motor 76. The head unit 3 is movably supported by the X-axis guide member, and a nut portion (not shown) provided in the head unit 3 is screwed with the X-axis ball screw shaft 77.

When the Y-axis servomotor 72 is operated, the head unit 3 moves in the Y direction along with the head unit supporting member 74. When the X-axis servomotor 76 is operated, the head unit 3 moves in the X direction with respect to the head unit support member 74. In this way, the head unit 3 moves between a position above the

component supply units

4 and 5 and a position above the mounting work position, and component pickup and transfer are performed.

The component supply unit 4 is disposed on the front side (+ Y side) of the substrate transfer mechanism 2. The component supply unit 4 has a structure in which a plurality of tape feeders 41 are arranged in parallel in the X direction. Each tape feeder 41 has a structure in which a tape containing relatively small chip components such as ics (integrated circuits), transistors, and capacitors is led out from a tape reel at a predetermined interval, and the components intermittently fed out by each tape feeder 41 are picked up by the head unit 3 and transferred to the substrate B at the mounting work position.

The component supply unit 5 is disposed on the rear side (-Y side) of the substrate conveyance mechanism 2. In the example shown in fig. 1, two component supply units 5 are arranged in the X direction, but since they have a common structure and perform the same operation, one component supply unit 5 will be basically described below. The device supply unit 5 has a configuration similar to that of the device supply apparatus disclosed in, for example, japanese patent laid-open No. 2006-198375, and supplies relatively large package devices such as qfp (quad Flat package) and bga (ball grid array). Specifically, the component supply section 5 includes a tray changer 6 capable of storing a plurality of trays P, and a tray conveying mechanism 51 for conveying the trays P in the Y direction between the tray changer 6 and the component supply position Ls. Then, the tray P on which the components are placed is pulled out to the component supply position Ls from the tray changer 6 by the tray conveying mechanism 51, and the components are supplied. That is, the components on the tray P pulled out to the component supply position Ls are picked up by the head unit 3 and transferred toward the substrate B at the mounting work position.

Incidentally, components are mounted on the tray P via the tray T. A plurality of package components are arranged on the tray T, and the tray P has a structure in which a single or a plurality of trays T are supported in a fixed state by a magnetic force or the like. In this embodiment, the tray P supplied to the component supply position Ls can be replaced by the tray changer 6.

Fig. 2 is a diagram schematically showing an example of the structure and operation of a tray changer provided in the component mounting apparatus illustrated in fig. 1. As shown in the drawing, the tray changer 6 includes a tray rack 61, and a plurality of accommodating portions S capable of accommodating the trays P are stacked in the Z direction on the tray rack 61. In the figure, in order to distinguish the plurality of housing portions S, integers from "1" to "10" are assigned to the reference numeral S (housing portions S1 to S10). The accommodating portions S1 to S10 accommodate the tray P in a horizontal state, and allow the tray P to be inserted and removed through an opening facing the front side in the Y direction (+ Y side). The tray changer 6 further includes an elevating unit 62 for elevating and lowering the tray rack 61. Therefore, by relatively moving the plurality of receiving portions S1 to S10 in the Z direction with respect to the tray conveying mechanism 51 by the lifting unit 62, one of the plurality of receiving portions S1 to S10 can be positioned at the insertion/removal position Li where the tray P can be delivered to/from the tray conveying mechanism 51.

Next, an example of the operation of the tray changer 6 will be described with reference to fig. 2. In fig. 2, an operation of returning the tray P drawn out to the component supply position Ls to the storage portion S1 and replacing the tray P by drawing out the tray P stored in the storage portion S3 to the component supply position Ls is exemplified. When the tray P is replaced, an insertion preparation operation is performed to prepare for insertion of the tray P being pulled out into the storage portion S. That is, as shown in the column of "insertion preparation operation" in fig. 2, the accommodating portion S1 as the insertion destination of the tray P being pulled out is positioned at the insertion/removal position Li. Next, as shown in the column of "insertion operation" in fig. 2, the tray conveying mechanism 51 inserts the tray P into the accommodating portion S1 positioned at the insertion/removal position Li. When the insertion operation is completed, a pull-out preparation operation for preparing to pull out the tray P from the storage section S is performed. That is, as shown in the column of "pull-out preparation operation" in fig. 2, the storage portion S3 in which the tray P to be pulled out next is stored is positioned at the inserting/removing position Li. Next, as shown in the "drawing operation" of fig. 2, the tray conveying mechanism 51 draws the tray P from the accommodating portion S3 positioned at the inserting and extracting position Li. Thus, the replacement of the tray P is completed. Although fig. 2 illustrates the tray replacement between the receiving portions S1 and S3, the tray replacement can be similarly performed between the receiving portions S different from them.

With the component supply unit 5 provided with such a tray changer 6, the worker appropriately performs a setup adjustment operation for accommodating the tray P in each accommodating portion S of the tray frame 61. In the present embodiment, a setup assist device for assisting the setup work is provided.

Fig. 3 is a block diagram schematically showing an example of an electrical configuration provided in the setup changeover supporting apparatus. The setup change adjustment support device 8 is realized by installing a setup change adjustment support program 80 in a computer, and supports setup change adjustment work by presenting trays P to be stored in the storage sections S1 to S10 to an operator. The setup program 80 may be provided by a recording medium 9 such as a cd (compact disc), dvd (digital Versatile disc), or usb (universal Serial bus) memory, or may be provided by downloading from an internet server.

The setup change assisting device 8 includes a processor, i.e., a calculation unit 81 including a cpu (central Processing unit) and a memory, a storage unit 82 including an hdd (hard Disk drive), and a display 83. The calculation unit 81 performs calculation necessary for setup assist. The storage unit 82 stores various kinds of information such as component supply information Is and component use information Iu required for setup change assistance. Here, the component supply information Is indicates the number of components that can be supplied from the 1 tray P for each type of component, and the component use information Iu indicates the number of components used in a substrate production plan for mounting the components supplied from the component supply unit 5 on the substrate B for each type of component. These pieces of information Is and Iu are input to the storage unit 82 by the operator in advance. Further, the display 83 displays the setup assist content calculated by the calculation unit 81.

Fig. 4 is a flowchart showing a first example of setup assist performed by the setup assist apparatus. The flowchart of the figure deals with the assistance of a setup operation for a substrate production plan for producing a plurality of single types (substrate types) of substrates B by repeating the operation of mounting a plurality of types Ca and Cb (component types) on the substrates B. The flowchart is executed by the calculation unit 81 based on the setup assist program 80. Here, after the operation of the flowchart of fig. 4 is described based on the specific example shown in fig. 5 to 8, the operation of the flowchart of fig. 4 is described based on another specific example shown in fig. 9 to 12.

Fig. 5 is a diagram showing a specific example of component supply information in the first example of the setup assist, fig. 6 is a diagram showing a specific example of component use information in the first example of the setup assist, fig. 7 is a diagram showing a specific example of a calculation result of the number of trays executed in the first example of the setup assist, and fig. 8 is a diagram showing a specific example of a calculation result of a setup method executed in the first example of the setup assist.

As shown in fig. 4, in step S101, the calculation unit 81 reads the component supply information Is and the component use information Iu from the storage unit 82. Then, the calculation unit 81 calculates the number of trays P required for the substrate production plan for each type of component (step S102). As shown in fig. 5, the number of components of the type Ca that can be placed on 1 tray P is 30, and the number of components of the type Cb that can be placed on 1 tray P is 18. In contrast, as shown in fig. 6, the number of elements of the type Ca used in the substrate production plan is 70, and the number of elements of the type Cb used in the substrate production plan is 90. Therefore, as shown in fig. 7, the number of trays P for the components of the type Ca required for the substrate production plan is 2.3 (70/30). At this time, since the trays P are supplied in units of 1 sheet, the number of the trays P required for the substrate production plan is 3. The number of trays of the component of the type Cb required for the substrate production plan is 5 (90/18).

In step S103, the calculation unit 81 determines whether all the pallets P required for the substrate production plan can be accommodated in the pallet rack 61 by one setup change operation based on the calculation result in step S102. In this example, since the total number of the trays P used in the substrate production plan is 8 (3 + 5), which is the maximum number of the trays P that can be accommodated in the tray rack 61, i.e., 10 or less, the calculation unit 81 determines yes in step S103 and proceeds to step S104.

In step S104, the calculation unit 81 determines an accommodating unit S for accommodating the tray P for the various Ca and Cb components used in the substrate production plan by the setup adjustment work, based on the calculation result in step S102 (step S104). As a result, as shown in fig. 8, the calculation unit 81 determines that the trays P on which the elements of the type Ca are mounted are individually accommodated in the accommodating portions S1 to S3, and the trays P on which the elements of the type Cb are mounted are individually accommodated in the accommodating portions S4 to S8. Thus, in one setup adjustment operation, 90 types Ca of elements are accommodated in the

tray frame

61, and 90 types Cb of elements are accommodated in the tray frame 61. Then, the display 83 displays the determination content in step S104 (step S105), and the setup assist in fig. 4 is ended.

Fig. 9 is a diagram showing another specific example of the component supply information in the first example of the setup assist, fig. 10 is a diagram showing another specific example of the component use information in the first example of the setup assist, fig. 11 is a diagram showing another specific example of the calculation result of the number of trays performed in the first example of the setup assist, and fig. 12 is a diagram showing another specific example of the calculation result of the setup method performed in the first example of the setup assist.

As shown in fig. 4, in step S101, the calculation unit 81 reads the component supply information Is and the component use information Iu from the storage unit 82. The calculation unit 81 calculates the number of trays P required for the substrate production plan for each type of component. As shown in fig. 9, the number of components of the type Ca that can be placed on the tray P is 30, and the number of components of the type Cb that can be placed on the tray P is 18. In contrast, as shown in fig. 10, the number of elements of the type Ca used in the substrate production plan is 184, and the number of elements of the type Cb used in the substrate production plan is 144. Therefore, as shown in fig. 11, the number of trays P for the components of the type Ca required for the substrate production plan is 6.1 (184/30), that is, 7. The number of trays of the component of the type Cb required for the substrate production plan is 8 (144/18).

In step S103, the calculation unit 81 determines whether all the pallets P required for the substrate production plan can be accommodated in the pallet rack 61 by one setup change operation based on the calculation result in step S102. In this example, since the total number of the trays P used in the substrate production plan is 15 (7 + 8) and is larger than the maximum number of the trays P that can be stored in the tray rack 61, that is, 10, the calculation unit 81 determines no in step S103 and proceeds to step S105.

In step S106, the calculation unit 81 calculates a ratio (usage ratio) of the number of trays P required for the substrate production plan according to each type of component. That is, the usage ratio of the number of trays P on which the components of the type Ca are mounted is calculated to be 6.1/14.1, and the usage ratio of the number of trays P on which the components of the type Cb are mounted is calculated to be 8/14.1. In the calculation of the usage ratio, the number of trays is an original value obtained by dividing the number of components required for the substrate production plan by the number of components that can be placed on the tray P.

In step S107, the calculation unit 81 allocates the 10 accommodating portions S of the tray rack 61 to the trays P of the respective types of components according to the usage ratio. That is, it is determined that 10 × 6.1/14.1 pieces of trays P on which components of the type Ca are placed are stored in the tray rack 61 by one setup adjustment operation, and the storage destinations are storage portions S1 to S4. Thus, 120 kinds Ca of elements are accommodated in the tray frame 61 in each setup work performed a plurality of times. Further, the tray P on which the components of the type Cb are placed is determined such that 10 pieces × 8/14.1 or 6 pieces are stored in the tray rack 61 by one setup adjustment operation, and the storage destinations are the storage portions S5 to S10. Thus, in each setup work performed a plurality of times, 108 types Cb of elements are accommodated in the tray frame 61. In this calculation, the decimal point or less is rounded off. Then, the display 83 displays the determination content in step S107 (step S105), and the setup assist in fig. 4 is ended.

In the embodiment described above, the number-of-sheets determining process is executed with the substrate B (a plurality of substrates B of a single type) as an execution target, which is not capable of accommodating all the trays P necessary for the production in the tray rack 61 by one setup operation (steps S106 and S107). Specifically, in the number-of-sheets determination process, the ratios of the number of sheets of the tray P required for producing the target substrate B to the respective types Ca and Cb of the components are obtained based on the component supply information Is and the component use information Iu (step S106). Then, the number of trays corresponding to the respective types Ca and Cb of the components accommodated in the tray frame 61 by the setup work for producing the substrate B to be executed is determined in accordance with the ratio (step S107). According to this embodiment, the elements of the respective types Ca and Cb used for producing the substrate B to be subjected to the sheet count determination process are accommodated in the tray frame 61 in the number corresponding to the ratio of the elements to be used. Thus, the elements of the respective kinds Ca and Cb are supplied from the element supplying section 5 at substantially the same timing as the substrate production is performed. Therefore, the frequency of the setup work can be suppressed as compared with the case where the setup work is performed each time the various types of elements are supplied at random timing. Thus, the frequency of setup adjustment work can be suppressed, and the burden on the operator can be reduced.

In particular, when all the trays P required for the production of a single type of the plurality of substrates B produced based on the substrate production plan cannot be accommodated in the tray rack 61 by one setup operation, the calculation unit 81 executes the number-of-sheets determination process with the single type of the plurality of substrates B as an execution target. In this way, when a plurality of substrates B of a single type are produced, the number of components of each type used for producing the substrate B to be executed is stored in the tray rack 61 in the number corresponding to the ratio of the components to be used by each type by executing the number-of-sheets determining process. As a result, the frequency of setup adjustment work can be suppressed, and the burden on the operator can be reduced.

Fig. 13 is a diagram showing a specific example of a substrate production plan as a target of the second example of the setup assist. The second example of the setup assist is different from the first example in that it is executed for a substrate production plan for producing a predetermined number of substrates in accordance with the production order from each of a plurality of types (substrate types) of substrates B11, B12, and the flowchart is basically in communication with fig. 4 of the first example. However, the specific operations in steps S106 and S107 differ depending on the substrate production schedule.

That is, in step S106, the calculation unit 81 calculates the ratios of the number of trays necessary for completing all the production of the plurality of types of substrates B11, B12 scheduled to be produced in the substrate production plan according to the respective types of components. Specifically, the number of trays P required for the entire production of the substrates B11, B12 is 18 (2 +4+8+ 4). Therefore, the usage ratio of the number of trays P on which the components of the kind Ca are mounted is calculated as 2/8, the usage ratio of the number of trays P on which the components of the kind Cb are mounted is calculated as 4/18, the usage ratio of the number of trays P on which the components of the kind Cc are mounted is calculated as 8/18, and the usage ratio of the number of trays P on which the components of the kind Cd are mounted is calculated as 4/18.

In step S107, the calculation unit 81 assigns the 10 accommodating portions S1 to S10 of the tray rack 61 to the trays P of the respective types of components according to the usage ratio. As a result, 1 tray P (10 × 2/18) to which the elements of the type Ca are assigned to the accommodating portions S1, 2 trays P (10 × 4/18) to which the elements of the type Cb are assigned to the accommodating portions S2 to S3, 4 trays P (10 × 8/18) to which the elements of the type Cc are assigned to the accommodating portions S4 to S7, and 2 trays P to which the elements of the type Cd are assigned to the accommodating portions S8 to S9.

Then, the storage destination of the thus distributed tray P is displayed on the display 83 (step S105), and the first setup adjustment is executed in accordance with the display result. In addition, even when some of the components run out as the substrate production is performed, the component tray P can be appropriately loaded to the tray rack 61.

In the embodiment described above, the number-of-sheets determination process is executed with all of the plurality of types of substrates B11 and B12 scheduled to be produced in the substrate production plan as execution targets (steps S106 and S107). Specifically, in the number-of-sheets determination process, the ratios of the number of trays P required for production of the target substrates B11, B12 to the respective types Ca, Cb, Cc, Cd of the components are obtained based on the component supply information Is and the component use information Iu (step S106). Then, the number of trays corresponding to the respective types Ca, Cb, Cc, Cd of the components accommodated in the tray frame 61 by the setup work for producing the substrates B11, B12 is determined in accordance with the ratio (step S107). According to this embodiment, the elements of the respective types Ca, Cb, Cc, and Cd used for producing the substrates B to be subjected to the sheet count determination process are accommodated in the tray frame 61 in the number corresponding to the ratio of the elements to be used. As a result, the frequency of setup adjustment work can be suppressed, and the burden on the operator can be reduced.

Fig. 14 is a flowchart showing a third example of setup assist performed by the setup assist device. The flowchart in this figure is executed by the calculation unit 81 based on the setup assist program 80. Fig. 15 is a diagram showing a specific example of a substrate production plan to be subjected to the third example of setup assist, and fig. 16 is a diagram showing another specific example of a calculation result of a setup method executed in the third example of setup operation. The third example of the setup assist corresponds to the setup assist operation for a substrate production plan in which a plurality of kinds (substrate kinds) of substrates B1, B2, B3, and B4 are produced in the production order, respectively, to produce a predetermined number of sheets. Specifically, a plurality of types Ca and Cb (component types) of elements are mounted on the substrate B1, a single type Cc of element is mounted on the substrate B2, a plurality of types Cd and Ce of elements are mounted on the substrate B3, and a single type Cf of element is mounted on the substrate B4.

As shown in fig. 14, in step S201, the calculation unit 81 reads the component supply information Is and the component use information Iu from the storage unit 82. Then, the calculation unit 81 calculates the number of trays P required for the substrate production plan for each type of component (step S202). As shown in fig. 15, the number of components of the types Ca, Cb, Cc, Cd, Ce, Cf that can be placed on the tray P is 30, 18, 16, 10, 20, respectively. In contrast, the number of elements of the types Ca, Cb, Cc, Cd, Ce, Cf used in the substrate production plan is 60, 54, 40, 80, 40, 100, respectively. Therefore, as shown in fig. 15, the number of trays P for the components of the types Ca, Cb, Cc, Cd, Ce, Cf required for the substrate production plan is 2, 3, 8, 4, 5, respectively.

After resetting the parameter M indicating the number of times of the setup work to zero (step S203), the calculation unit determines whether all the trays P necessary for the substrate production plan can be accommodated in the tray rack 61 by one setup work based on the calculation result of step S202 (step S204). When it is determined that all the trays P can be accommodated (yes in step S204), the process proceeds to step S205, and the accommodation destination of each tray P in the setup job is determined in the same manner as in step S104. Then, the display 83 displays the determination content in step S104 (step S206), and the setup assist in fig. 14 is ended.

On the other hand, if it is determined that all the trays P cannot be accommodated (no in step S204), the process proceeds to step S207. In the specific example shown in fig. 15 and 16, the number of trays P required for the substrate production plan is 25, which is more than 10, and therefore the determination in step S204 is no. Then, in step S207, the parameter M is incremented.

In step S208, the calculation unit 81 determines whether all the trays P corresponding to the first produced substrate B among the trays P which are not yet assigned to the setup work can be accommodated in the tray rack 61 in the mth setup work. Here, since the 10 accommodating portions S1 to S10 of the tray rack 61 are empty, it is determined that 5 trays P of the components of the types Ca and Cb used for the production of the target board B1 can be accommodated by the M-th setup operation (yes in step S208). Thus, in step S209, the 5 trays P are allocated to the mth (first) setup job. Thus, as shown in fig. 16, it is determined that the tray P of the component of the type Ca is accommodated in the accommodating portions S1 to S2 in the mth (first) setup operation, and the tray P of the component of the type Cb is accommodated in the accommodating portions S3 to S5 in the mth (first) setup operation, and the process returns to step S208.

In the second step S208, the calculation unit 81 determines whether all the trays P corresponding to the board B2 can be accommodated by the M-th setup job. Here, since the five accommodating portions S6 to S10 of the tray rack 61 are empty, it is determined that 3 trays P of the components of the type Cc used for the production of the target substrate B2 can be accommodated by the M-th setup operation (yes in step S208). Thus, in step S209, the 3 trays P are allocated to the mth (first) setup job. Thus, as shown in fig. 16, it is determined that the tray P of the component of the type Cc is accommodated in the accommodating portions S6 to S8 in the mth (first) setup job, and the process returns to step S208.

In step S208 of the third time, the calculation unit 81 determines whether all the trays P corresponding to the board B3 can be accommodated by the M-th setup job. Here, the number of the trays P corresponding to the board B3 is 12, which is the sum of the number of the trays P of the Cd-type elements (8) and the number of the trays P of the Ce-type elements (4). In contrast, the number of the accommodating portions S9 and S10 that are vacant in the tray rack 61 is 2, and is smaller than the number of target trays P (12). Therefore, it is determined in step S208 that the storage is impossible (no), and the process proceeds to step S210.

In step S210, it is determined whether or not the number of empty storage units S9, 10 is equal to or greater than a predetermined number (e.g., 3). Here, since the number of empty accommodating portions S9 and S10 is 2 but less than 3, the determination in step S210 is no, and the process proceeds to step S213. Then, in step S213, it is determined whether or not allocation to a setup job is determined for all the trays P used in the substrate production plan. Here, since the assignment to the setup job is not determined for the tray P used in the production of the boards B3 and B4, the process returns to step S204.

In step S204, since all trays P used for production of boards B3 and B4 cannot be accommodated by one setup job, it is determined as no. Then, after the parameter M is incremented in step S207, the process proceeds to step S208. In step S208, the calculation unit 81 determines whether all the trays P corresponding to the board B3 can be accommodated by the M-th setup job. Here, the number of trays P corresponding to the board B3 is 12, whereas the number of accommodating portions S1 to S10 that are vacant in the tray rack 61 is 10, which is smaller than the number of target trays P (12). Therefore, it is determined in step S208 that the storage is impossible (no), and the process proceeds to step S210.

In step S210, it is determined whether or not the number of empty storage units S1-10 is equal to or greater than a predetermined number (e.g., 3). Here, since the number of empty accommodating portions S1 to S10 is 10 and 3 or more, the determination in step S210 is yes, and the process proceeds to step S211. In step S211, the calculation unit 81 calculates the ratio (usage ratio) of the number of the trays P required for the production of the target board B3 to each type of the component. That is, the usage ratio of the number of trays P on which the elements of the kind Cd are mounted is calculated as 8/12, and the usage ratio of the number of trays P on which the elements of the kind Ce are mounted is calculated as 4/12.

In step S212, the calculation unit 81 allocates the empty 10 accommodating portions S1 to S10 in the tray rack 61 to the trays P of the respective types of components according to the usage ratio. Here, the ratio of the number of trays P on which the elements of the type Cd are mounted to the number of trays P on which the elements of the type Ce are mounted is set to 8/12: 4/12, determine the respective storage destinations. As a result, in the mth (second) setup work, 6 trays P on which the elements of the type Cd are placed are stored, and their storage destinations are determined as the storage sections S1 to S6. In the mth (second) setup work, 3 trays P on which the elements of the type Ce are placed are stored, and their storage destinations are determined as storage sections S7 to S9.

Next, in step S213, it is determined whether or not allocation to a setup job is determined for all the trays P used in the substrate production plan. Here, since the assignment to the setup job is not determined for a part of trays P used in the production of the board B3 and a part of trays P used in the production of the board B4, the process returns to step S204. The remaining trays P are 3 trays P of the kind Cd, Ce used in the production of the substrate B3 and 5 trays P of the kind Cf used in the production of the substrate B4. Therefore, in step S204, it is determined that the remaining trays P can be accommodated in the setup job once (yes), and the process proceeds to step S205, where the accommodation destination of each tray P in the setup job is determined in the same manner as in step S104. Then, in step S213, it is determined that the assignment to the setup job has been determined for all trays (yes), and the display 83 displays the determination content shown in fig. 16 (step S206). Thus, the setup assist of fig. 14 ends.

In the embodiment described above, the number-of-sheets determining process is executed with the substrate B3 as an execution target, which cannot accommodate all the trays P necessary for the production in the tray rack 61 by one setup operation (steps S211 and S212). Specifically, in the number-of-sheets determination process, the ratios of the number of sheets of the tray P required for production of the target substrate B3 to the respective types Cd and Ce of the components are obtained based on the component supply information Is and the component use information Iu (step S211). Then, the number of trays corresponding to the respective types Cd and Ce of the components accommodated in the tray rack 61 by the setup work for producing the substrate B3 to be executed is determined in accordance with the ratio (step S212). According to this embodiment, the elements of each kind Cd and Ce used in the production of the substrate B3 to be subjected to the sheet count determination process are accommodated in the tray frame 61 in the number corresponding to the ratio of the elements to be used. Thus, the elements of the respective kinds Cd, Ce are fed out from the element supply section 5 at substantially the same timing as the substrate production is performed. Therefore, the frequency of the setup work can be suppressed as compared with the case where the setup work is performed each time the various types of elements are supplied at random timing. Thus, the frequency of setup adjustment work can be suppressed, and the burden on the operator can be reduced.

The calculation unit 81 executes a pallet determination process for determining the pallets P stored in the pallet rack 61 by the multiple setup operations based on the production order (steps S204 and S207 to S213). When all the trays P necessary for the production cannot be accommodated in the tray rack 61 by one setup operation, the number-of-sheets determining process is executed with the substrates B3 of the types Cd and Ce determined in the tray determining process as targets. In this way, even when a plurality of types of substrates B1 to B4 are produced in sequence, the number of elements of each type Cd or Ce used for production of the substrate B3 to be executed can be stored in the tray rack 61 in the number corresponding to the ratio of the elements used. As a result, the frequency of setup adjustment work can be suppressed, and the burden on the operator can be reduced.

The present invention is not limited to the above-described embodiments, and various modifications can be made to the above-described embodiments without departing from the gist thereof. For example, the number of pallets P that can be stored in the pallet rack 61 is not limited to 10. That is, the tray rack 61 may be configured to accommodate a plurality of trays P.

In addition, the specific structure of the tray frame 61 can be changed as appropriate. For example, when the elements of the pallet P are thicker than a predetermined thickness, the pallet frame 61 may be configured such that a flat plate between two adjacent accommodating portions S can be removed and the two accommodating portions S can be used as one accommodating portion S. That is, the number of the trays P that can be accommodated in the tray rack 61 can be changed according to the thickness of the components placed on the trays P. However, there is an upper limit (10 sheets in the example of fig. 2) in the variable range of the number of the trays P, and the number of the trays P can be changed within the variable range. When such trays P are used, the number of the trays P corresponding to each type of the components accommodated in the tray rack 61 by one setup change adjustment operation may be determined in the number-of-sheets determination process in accordance with a change in the number of the trays P that can be accommodated in the tray rack 61. This configuration enables the pallet rack 61 to accommodate the appropriate number of pallets P corresponding to the change in the number of pallets P that can be accommodated by the pallet rack, by each setup change operation, which contributes to efficient setup change operations.

The flowcharts of fig. 4 and 14 may be modified as appropriate. For example, in the flowchart of fig. 14, when the number of empty accommodating units S is equal to or greater than a predetermined number in step S210, the number of trays P equal to or greater than the predetermined number is not allocated to the targeted setup job. However, step S210 may be omitted, and the tray P may be assigned to the targeted setup work as long as there is a free accommodating portion S in the tray rack 61.

Alternatively, in the example of fig. 14, that is, the third example, there may be a restriction that the components for the type of substrate B, the components of which are depleted from the tray frame 61 during the production thereof, are not accommodated in the tray frame 61 by the same setup adjustment as the accommodation of the components for the other type of substrate B in the tray frame 61. That is, as shown in fig. 16, the Cd, Ce-like elements used in the production of the substrate B3 run out of the tray frame 61 in the middle of the production of the substrate B3. Therefore, in the third example, the remaining elements of the types Cd and Ce for the substrate B3 are accommodated in the tray frame 61 by the same setup adjustment as that for the element of the type Cd for the substrate B4. On the other hand, the types Cd and Ce for the substrate B3 may be replaced by a different setup from the replacement of the types Cd and Ce for the substrate B4 in order to replenish the surplus during the production of the substrate B3. At this time, in the second setup, for example, instead of 6 trays P, 7 trays of Cd-type components may be accommodated.

The numerical values shown in fig. 5 to 8, 15, and 16 are only examples. Therefore, in the operation example using rounding, the decimal point or less may be rounded instead of rounding. Further, when all the number of the specific type of pallets P obtained from the calculation result by the decimal point or less processing method is not stored in the pallet rack 61, the subtraction processing of reducing the number of the specific type of pallets P by 1 may be appropriately performed. In short, the result of simply calculating the number of pallets P based on the usage ratio may include a decimal point or less, whereas the unit capable of storing pallets P in the tray rack 61 is 1, and therefore, the number of pallets P stored in the tray rack 61 may be appropriately adjusted by applying an appropriate operation to the calculation result obtained based on the usage ratio.
