After that, the component transfer device collects the component of the component type from the reset component supply unit. In addition, the parts supply unit set in the shared spare unit holding unit is removed. By doing so, the component sampling device can perform the operation of mounting each component on the board in the same procedure as before the component shortage occurred.

Japanese Unexamined Patent Publication No. 2005-235952

However, in the above-mentioned method, the parts supply unit set in the shared spare unit holding portion is only temporarily used, and separately, it is necessary to prepare a parts supply unit of a part type that has run out of parts. There was, and the work was complicated by that much.

This disclosure is made to solve the above-mentioned problems, and when a part shortage occurs during the processing of a production job, each part can be smoothly mounted on the board in the same procedure as before the part shortage occurred. The main purpose is to do.

The production job processing method of the present disclosure is
A component supply unit having a plurality of supply unit holding units in which a plurality of component supply units for supplying components of different component types are set to be detachably set, and a component sampled from each component supply unit and mounted on a board. A method of processing a predetermined production job using a component mounting machine equipped with a component transfer device.
(A) Before processing the production job, the number of the component supply units corresponding to the component types of all the components to be mounted on the board is set in the main area of the component supply unit, and the production job is performed. A process of setting a spare component supply unit of a component type that is expected to run out during processing in a sub-region of the component supply unit, and a process of setting the spare component supply unit.
(B) After the processing of the production job is started, the parts transfer device is made to collect parts from the parts supply unit set in the main area and mount them on the substrate, and during the processing of the production job, the parts are mounted. If a component shortage occurs in the component supply unit set in the main area, the component transfer device is made to collect the component of the component type that has been out of component from the spare component supply unit and the substrate. A guide for replacing the spare component supply unit with the out-of-component component supply unit set in the main area is output to the display device, and the replacement operation is completed. Then, a step of causing the component transfer device to again collect components from the component supply unit set in the main area and mount them on the substrate.
Is included.

In this production job processing method, when a part shortage occurs in the parts supply unit set in the main area, the spare parts supply unit set in the sub area is used, so that the production job processing is continued. It can be carried out. At the same time, a guide prompting replacement work for replacing the spare parts supply unit in the sub area with the out-of-parts parts supply unit set in the main area is displayed. The operator who sees the guidance carries out the replacement work. When the replacement work is completed, the component transfer device is made to collect the components from the component supply unit set in the main area again and mount them on the board. In this way, the spare parts supply unit is not only temporarily used, but is finally moved to the main area and continues to be used. Therefore, it is not necessary to prepare a parts supply unit for a part type that has run out of parts separately from the spare parts supply unit. Therefore, when a component shortage occurs during the processing of a production job, each component can be smoothly mounted on the board in the same procedure as before the component shortage occurred.

The production job processing apparatus of the present disclosure is
A component supply unit having a plurality of supply unit holding units in which a plurality of component supply units for supplying components of different component types are set to be detachably set, and a component sampled from each component supply unit and mounted on a board. A production job processing device that processes a predetermined production job using a component mounting machine equipped with a component transfer device.
Before processing the production job, the number of the component supply units corresponding to the component types of all the components to be mounted on the board is set in the main area of the component supply unit, and the production job is being processed. A spare component supply unit for a component type that is expected to run out of components is set in a sub-region of the component supply unit.
After the processing of the production job is started, the production job processing apparatus causes the component transfer device to collect parts from the component supply unit set in the main area and mount them on the substrate to process the production job. If a part shortage occurs in the parts supply unit set in the main area, the parts of the part type that have become out of parts are collected from the spare parts supply unit in the parts transfer device. The spare parts supply unit is mounted on the board, and a guide for exchanging the spare parts supply unit with the parts out of parts set in the main area is output to the display device to prompt the replacement work. When the work is completed, the component transfer device is made to collect components from the component supply unit set in the main area again and mount them on the substrate.
It is a thing.

Since this production job processing device is a device that implements the above-mentioned production job processing method, it has the same effect as the above-mentioned production job processing method, for example, when a part runs out during the processing of a production job, the parts run out smoothly. The effect that each component can be mounted on the board can be obtained by the same procedure as before the occurrence.

The feeder 50 rotates the sprocket of the tape feeding mechanism 57 and feeds the tape 52 engaged with the sprocket rearward. The film covering the component accommodated in the accommodating recess of the tape 52 is peeled off before reaching a predetermined component supply position (see FIG. 1). The component is attracted to the nozzle 44 at this component supply position. As shown in FIG. 3, the feeder 50 has a built-in feeder control device 58 that controls the entire feeder. The feeder control device 58 is composed of a well-known CPU, ROM, RAM, etc., and outputs a drive signal to the drive motor of the tape feed mechanism 57.

As shown in FIG. 2, the feeder table 60 has a plurality of slots 62 on the upper surface. The slot 62 is an inverted T-shaped groove extending in the front-rear direction, and the rail 56 of the feeder 50 is inserted into the slot 62. The feeder table 60 has a vertical wall at the rear end. The vertical wall is provided with a connector 65 at a position corresponding to each slot 62, and positioning holes 64 and 64 are provided above and below the connector 65. When the rail 56 of the feeder 50 is inserted from the front to the rear of the slot 62, the positioning pins 54 and 54 of the feeder 50 are fitted into the positioning holes 64 and 64 of the feeder base 60, and the connector 55 of the feeder 50 is inserted into the feeder base. It is electrically connected to the connector 65 of 60. As a result, power is supplied to the feeder 50 from the component mounting machine 20. Further, as shown in FIG. 3, the feeder control device 58 is capable of bidirectional communication with the mounting control device 70 via the connectors 55 and 65, and is capable of bidirectional communication with the management computer 80 via the mounting control device 70. become.

In addition to this, the component mounting machine 20 includes a touch panel type display operation panel 24 for displaying various information and accepting input operations from an operator.

As shown in FIG. 3, the mounting control device 70 outputs a drive signal to the board transfer device 22, the head moving device 30, the head unit 40, and the like, and also outputs an image signal to the display operation panel 24. The mounting control device 70 inputs an image signal from the parts camera 39 and an input signal from the display operation panel 24. The mounting control device 70 can perform bidirectional communication with the feeder control device 58 and the management computer 80.

The management computer 80 is composed of a well-known CPU, ROM, HDD, RAM, and the like, and includes a display 82 such as an LCD and an input device 84 such as a keyboard and a mouse as shown in FIG. The management computer 80 is capable of bidirectional communication with the mounting control device 70 of the component mounting machine 20, and is capable of bidirectional communication via the feeder control device 58 of the feeder 50 and the mounting control device 70. The production job is stored in the HDD of the management computer 80.

Next, the operation of the management computer 80 will be described. The management computer 80 executes the pre-production job processing work routine. FIG. 4 is a flowchart showing an example of a work routine before processing a production job. When the input device 84 inputs the start instruction of the pre-production job processing work, the management computer 80 reads the program of the pre-production job processing work from the HDD and executes the program. The feeder 50 of the part type X used at the start of the processing of the production job is referred to as the feeder 50X, the first spare feeder 50 of the part type X is the feeder 50X1, the second spare feeder 50 is the feeder 50X2, and so on. Called ... Further, the number of slots 62 of the feeder stand 60 is set to 11 for convenience, and the slots 62 of # 1 to # 11 are referred to in order from the left.

The management computer 80 first acquires a production job (S100). The production job is stored in the HDD of the management computer 80. Table 1 shows an example of a production job. The production job includes the planned number of production, the type of parts, the number of mounting points per board of each part type, the number of remaining parts before production, the number of reel parts, and the like. The planned production number is the planned production number of mounted boards on which a large number of components are mounted on the board 12. The component types are all component types mounted on the substrate 12. The number of remaining parts before production is the number of remaining parts remaining on the tape 52 wound on the reel 51 of the feeder 50 used at the start of processing of the production job. The number of parts on the reel is the number of parts held by the tape 52 wound on the new reel 51. These pieces of information are input by the operator via the input device 84, or are input by the management computer 80 from the mounting control device 70 and the feeder control device 58 by communication.

Next, the management computer 80 determines the slot position of the feeder 50 and the slot position of the spare feeder 50 to be used at the start of the processing of the production job, and displays them on the display 82 and the display operation panel 24 of the component mounting machine 20 ( S110). The slot position of the feeder 50 to be used and the slot position of the spare feeder 50 are determined as follows, for example.

That is, the management computer 80 creates a graph for each component type based on the production job, with the horizontal axis representing the number of mounted substrates produced and the vertical axis representing the number of remaining parts of the feeder. When this graph is created for each part type based on the production jobs in Table 1, it is as shown in FIG. As for the parts of the part type A, the remaining number of pre-production parts of the feeder 50A at the start of processing is 800, and the number of mounting points per substrate is 20. Therefore, the feeder 50A is out of parts when the number of production sheets reaches 40. After that, the parts of the part type A are supplied from the spare feeder 50A1. The number of parts of the reel 51 of the spare feeder 50A1 is 1400. Therefore, the spare feeder 50A1 is out of parts when the number of production sheets reaches 110 (= 40 sheets + 70 sheets). After that, the parts of the part type A are supplied from another spare feeder 50A2. The spare feeder 50A2 runs out of parts when the number of production sheets reaches 180. Then, another spare feeder 50A3 supplies the parts of the part type A. After that, the number of spare feeders 50A3 produced reaches 200 without any parts being cut off. For the parts of part types B to E, a graph is created in the same manner. From these graphs, the number of parts cut in the production job, the timing of parts cut, the type of parts to be cut, and the number of parts cut for each part type are obtained. The results are shown in Table 2.

The management computer 80 determines the slot positions of the various feeders 50 based on the contents of Tables 1 and 2. The management computer 80 recognizes that there are five component types A to E for all the components to be mounted on one board 12, and determines the slot positions of the feeders 50A to 50E used at the start of the processing of the production job. decide.

Here, the slot position is determined so that the production time per substrate is shortened. The nozzle 44 moves to the component supply position of the feeder 50 to attract the component, then passes above the component camera 39 and then moves to the substrate 12. The parts camera 39 takes an image of the parts attracted to the nozzle 44 from below. The mounting control device 70 recognizes the positional deviation and orientation of the component attracted to the nozzle 44 based on the captured image, and mounts the component at a predetermined position on the substrate 12 in consideration of the positional deviation and orientation of the component. .. In this way, the nozzle 44 always passes above the parts camera 39 after adsorbing the parts supplied by the feeder 50, and then heads for the substrate 12. Therefore, the moving distance (moving time) of the nozzle 44 becomes shorter as the feeder 50 is set in the slot 62 closer to the parts camera 39 (center in this case) of the feeder stand 60. Therefore, it is preferable to set the feeder 50, which supplies a component type having a large number of mounting points per substrate, in the slot 62 near the center of the feeder base 60 in order to shorten the production time per substrate.

Now, in the production jobs in Table 1, if the component types are arranged in descending order of the number of mounting points per substrate, they are A, B, C, D, and E. As described above, the feeder base 60 has slots 62 of # 1 to # 11, and slot 62 of # 6 is located at the center. Therefore, the management computer 80 determines the slot positions of the feeders 50A to 50E to be used at the start of processing of the production job as shown in FIG. That is, the feeder 50A is determined to be # 6, the feeder 50B is determined to be # 5, the feeder 50C is determined to be # 7, the feeder 50D is determined to be # 4, and the feeder 50E is determined to be # 8. The area (here, # 4 to # 8) in which the feeders 50A to 50E used at the start of the production job are set in the feeder table 60 is referred to as a main area.

Further, referring to Table 2, when the component types are arranged in order from the one with the earliest component cut timing, the results are A, D, A, B, D, and A. Therefore, the management computer 80 determines the slot positions of the spare feeders 50A1, 50D1, 50A2, 50B1, 50D2, 50A3 in this order from the slots 62 near the main area as shown in FIG. That is, the feeder 50A1 is determined to be # 3, the feeder 50D1 is determined to be # 9, the feeder 50A2 is determined to be # 2, the feeder 50B1 is determined to be # 10, the feeder 50D2 is determined to be # 1, and the feeder 50A3 is determined to be # 11. The regions (# 1 to # 3, # 9 to # 11) in which the spare feeders 50A1, 50D1, 50A2, 50B1, 50D2, 50A3 are set are referred to as sub-regions.

The management computer 80 determines the slot positions of the feeders 50 of each component type to be set in the main area and the sub area as described above, and then displays them on the display 82 and the display operation panel 24 of the component mounting machine 20. As the screen at this time, for example, the display screen SC of FIG. 6 may be adopted. The operator sets the feeder 50 of each component type on the feeder stand 60 while observing the display screen SC.

After that, the management computer 80 determines whether or not the feeder 50 is set in all the slots 62 of the main area and the sub area (S120). This determination is made based on whether or not the connector 55 of the feeder 50 is connected to the connector 65 of all the slots 62 in the main area and the sub area. If the negative determination is made in S120, the management computer 80 stands by as it is. On the other hand, if the affirmative determination is made in S120, the management computer 80 determines whether or not the feeder 50 inserted in each slot 62 is correctly set (S130). The management computer 80 receives the feeder ID from the feeder control device 58 via the mounting control device 70, accesses a management database (not shown), and holds the feeder ID on the tape 52 wound on the reel 51 of the feeder 50. Read out the part type, and determine whether the correspondence between the slot position and the part type is correct.

If a negative determination is made in S130, the management computer 80 displays an error on the display operation panel 24 of the display 82 and the component mounting machine 20 (S140), waits for the operator to correctly set the feeder 50, and then again in S120. Return to. On the other hand, if all the feeders 50 of each component type are set correctly in S130, the management computer 80 ends this routine.

Next, the operation of the component mounting machine 20 will be described. After the pre-production job processing work is completed, the mounting control device 70 of the component mounting machine 20 executes the production job processing routine. FIG. 7 is a flowchart showing an example of a production job processing routine. When the production job processing start instruction is input from the display operation panel 24, the mounting control device 70 reads the production job processing program from the HDD and executes it.

When the mounting control device 70 starts the production job processing routine, the mounting control device 70 first carries in and supports the substrate 12 (S200). Here, the mounting control device 70 controls the board transfer device 22 so that the board 12 is carried into the component mounting machine 20, and the board 12 reaches a predetermined take-in position (the position of the board 12 in FIG. 1). At that time, the substrate 12 is supported by the support pins 28.

Subsequently, the mounting control device 70 controls the head moving device 30 and the head unit 40 so that the components supplied from the feeder 50 in the main region for all component types are mounted on the substrate 12 (S210). Here, the head moving device 30 and the head unit 40 attract a part of a predetermined part type from a plurality of feeders 50 in the main region to the nozzle 44, and the nozzle 44 is passed through the upper part of the parts camera 39 to the substrate. Move to a predetermined position of 12 and release the part at that position. Subsequently, the mounting control device 70 determines whether or not all the components are mounted on the substrate 12 (S220). Here, the mounting control device 70 performs this determination based on whether or not a component shortage occurrence signal has been received from the feeder control device 58 of each feeder 50. When the feeder control device 58 of each feeder 50 recognizes that a component shortage has occurred by a tape sensor (not shown) provided in the feeder 50, the feeder control device 58 transmits a component shortage occurrence signal to the mounting control device 70.

If all the components have not been mounted in S220, the mounting control device 70 determines whether or not the feeder 50 is out of parts (S230). If no component shortage has occurred in S230, the mounting control device 70 returns to S210 and continues component mounting using the feeder 50 in the main region. On the other hand, if a component shortage occurs in S230, the mounting control device 70 mounts the component supplied from the spare feeder 50 in the sub-region on the board 12 for the component type that has run out, and the remaining component. As for the product type, the head moving device 30 and the head unit 40 are controlled so that the components supplied from the feeder 50 in the main region are mounted on the substrate 12 (S240). Therefore, even if a component is cut off, the component mounting machine 20 can continue without stopping the component mounting. However, since the spare feeder 50 in the sub region is farther from the parts camera 39 than the feeder 50 in the main region, the component mounting of S240 takes longer than the component mounting of S210.

Subsequently, the mounting control device 70 determines whether or not it is necessary to move the spare feeder 50 of the part type that is predicted to be out of parts next to the main area, and the spare that is not set in the feeder stand 60. It is determined whether or not it is necessary to prepare the feeder 50 of the above (S250). If the spare feeder 50 of the part type that is expected to be out of parts next is already placed in the sub area, if this spare feeder 50 is moved to the immediate vicinity of the main area, the next out of parts will occur. The moving distance (time) of the head unit 40 when it occurs can be shortened. Further, when there is a spare feeder 50 that has not yet been set in the feeder stand 60, if the spare feeder 50 is prepared in case of a part shortage in the future, the production can be continued when the part shortage actually occurs. If both are unnecessary in S250, the mounting control device 70 displays a guide (replacement guide) prompting replacement work to replace the spare feeder 50 with the out-of-parts feeder 50 set in the main area. Output to 24 (S252). If movement is necessary but preparation is not necessary in S250, the mounting control device 70 should move the spare feeder 50 of the part type that is expected to be out of parts next to the main area together with the replacement guide. (Movement guidance) is output to the display operation panel 24 (S254). If movement is not necessary in S250 but preparation is necessary, the mounting control device 70 prepares a spare feeder 50 that is not set in the feeder stand 60 and sets it in the empty slot 62 in the sub area together with the replacement guide. (Preparation guide) is output to the display operation panel 24 (S256). If movement and preparation are required in S250, the mounting control device 70 outputs replacement guidance, movement guidance, and preparation guidance to the display operation panel 24 (S258). The operator performs the work according to the guidance displayed on the display operation panel 24.

After any of the processes S252 to S258, the mounting control device 70 determines whether or not all the components are mounted on the substrate 12 (S260). If all the components have not been mounted in S260, the mounting control device 70 determines whether or not the replacement work has been completed (S270). The mounting control device 70 makes this determination by performing bidirectional communication with the feeder control device 58 of the feeder 50 connected to the connector 65 of the slot 62 in which the component is cut off. Specifically, the mounting control device 70 receives the feeder ID from the feeder control device 58 of the feeder 50, and does the received feeder ID match the ID of the spare feeder 50 of the part type that has run out of parts? Whether or not the replacement work is completed is determined by whether or not. If the replacement work is not completed in S270, the mounting control device 70 returns to S240 again. On the other hand, when the replacement work is completed in S270, the process returns to S210 again.

When all the components are mounted on the board 12 in S220 or S260, the mounting control device 70 releases the support of the board 12 and carries it out (S280). Here, the mounting control device 70 controls the board transfer device 22 so that the board 12 is carried out from the component mounting machine 20 after the support pin 28 releases the support of the board 12. Subsequently, the mounting control device 70 determines whether or not the production number of the board 12 on which the components have been mounted has reached the planned production number (S290), and if not, returns to S200 again and if it has reached. If this routine is terminated.

Next, the above-mentioned production job processing routine will be specifically described with reference to Tables 1 and 2 as examples. At the start of the processing of the production job, as shown in FIG. 8A, the components supplied from the feeders 50A to 50E in the main regions (# 4 to # 8) are mounted on the substrate 12. When the number of production sheets reaches 40, the part type A runs out of parts. Therefore, the parts of the part type A are supplied from the spare feeder 50A1 in the sub area, and the remaining parts are supplied from the feeders 50B to 50E in the main area. It is supplied (Fig. 8 (b)). At this time, the exchange guide is displayed on the display operation panel 24. The operator replaces the spare feeder 50A1 with the out-of-part feeder 50A according to this replacement guide (FIG. 8 (c)). Then, after that, the components supplied from the feeders 50A1, 50B to 50E in the main region are mounted on the substrate 12. When the number of production sheets reaches 50, the part type D runs out of parts. Therefore, the parts of the part type D are supplied from the spare feeder 50D1 in the sub area, and the remaining parts are supplied from the feeders 50A1, 50B in the main area. It is supplied from 50C and 50E (FIG. 8 (d)). At this time, the exchange guide and the movement guide are displayed on the display operation panel 24. According to this replacement guide and movement guide, the operator replaces the spare feeder 50D1 with the out-of-part feeder 50D, and then replaces the spare feeder 50A2 of the part type A, which is out of parts, with the slot immediately next to the main area. (Fig. 8 (e)). When the number of production reaches 110, the part type A runs out of parts. Therefore, the parts of the part type A are supplied from the spare feeder 50A2 in the sub area, and the remaining parts are supplied from the feeders 50B and 50C in the main area. It is supplied from 50D1 and 50E (FIG. 8 (f)). At this time, the exchange guide and the movement guide are displayed on the display operation panel 24. According to this replacement guide and movement guide, the operator replaces the spare feeder 50A2 with the out-of-part feeder 50A1 and then replaces the spare feeder 50B1 of the part type B that is out of parts with the slot immediately next to the main area. (Fig. 8 (g)). Hereinafter, the processing is performed in the same manner as in Tables 1 and 2 (FIGS. 8 (h) to 8 (m)).

Here, the correspondence between the components of the present embodiment and the components used in the production job processing method of the present disclosure will be clarified. The feeder 50 of the present embodiment corresponds to the parts supply unit used in the production job processing method of the present disclosure, the feeder stand 60 corresponds to the parts supply unit, the slot 62 corresponds to the supply unit holding unit, and the head moving device 30. The head unit 40 corresponds to the component transfer device, and the display 82 and / or the display operation panel 24 corresponds to the display device. Further, the mounting control device 70 of the component mounting machine 20 corresponds to the production job processing device of the present disclosure.

According to the embodiment described in detail above, the spare feeder 50 is not only temporarily used, but is finally moved to the main area and continues to be used. Therefore, it is not necessary to prepare a feeder 50 of a part type that has run out of parts separately from the spare feeder 50. Therefore, when a component shortage occurs during the processing of the production job, each component can be smoothly mounted on the substrate 12 in the same procedure as before the component shortage occurred (that is, using the feeder 50 in the main region).

Further, the feeder 50 used at the start of the processing of the production job is set in the main area in a layout in which the production time per substrate is predicted to be the shortest. Therefore, the production job can be processed in a short time.

Further, the spare feeder 50 of the component type whose timing is predicted to run out is set so as to be closer to the main region. Therefore, it is possible to shorten the time required for the component transfer device (head moving device 30 and head unit 40) to suck the component and mount it on the substrate 12 from the spare feeder 50 of the component type that has run out of component. ..

Furthermore, if it is necessary to move the spare feeder 50 of the part type that is expected to run out next to the slot 62 immediately adjacent to the main area, a guide prompting the work is displayed. The operator performs the moving work according to this guidance. Therefore, when a component is cut off next time, the component transfer device (head moving device 30 and head unit 40) sucks the component from the spare feeder 50 of the component type that has been cut off and mounts the component on the substrate 12. The time required for this can be shortened.

Also, the planned number of production, the number of mounting points per board, the number of remaining parts of each feeder used at the start of processing of the production job (the number of remaining parts before production), and the number of parts of each spare feeder. Based on the above, the timing of parts shortage of each part type and the number of replacements of each parts supply unit are predicted, and each spare feeder 50 is set in the sub-region based on the prediction result. Therefore, the spare feeder 50 can be appropriately set in the sub-region.

It goes without saying that the present invention is not limited to the above-described embodiment, and can be implemented in various aspects as long as it belongs to the technical scope of the present invention.

For example, in the above-described embodiment, the number of slots 62 of the feeder stand 60 is described as 11 (# 1 to # 11), but as shown in FIG. 9, the number of slots 62 is 9 (# 1 to # 11). 9) may be used. In that case, assuming that the production job is processed according to Tables 1 and 2, the feeders 50A to 50E used at the start of the production job processing are set in the main areas of # 3 to # 7. Further, spare feeders 50A1, A2, B1, D1 are set in the sub-regions of # 1, # 2, # 8, and # 9. However, the spare feeders 50D2 and 50A3 used at the end of the processing of the production job cannot be set on the feeder stand 60. In this case, when the production job is processed, the feeder 50 on the feeder table 60 changes as shown in FIGS. 10A to 10M. In FIGS. 10 (a) to 10 (h), the transition is the same as in FIGS. 8 (a) to 8 (h), but in FIG. 10 (h), the spare feeder 50B1 of # 8 is out of parts # 4. When replacing the feeder 50B of the above, the mounting control device 70 determines that a spare feeder 50D2 of the component type D, which is predicted to cause a part shortage next, is required, and guides the preparation of the spare feeder 50D2 ( Preparation guide) is output to the display operation panel 24. This preparation guide prompts the spare feeder 50D2 to be set in slot 62 of # 2 immediately adjacent to the main area. The operator sets the spare feeder 50D2 in slot 62 of # 2 according to this guidance (FIG. 10 (i)). After that, the feeder 50D1 of the component type D is out of parts, and the spare feeder 50D2 supplies the components (FIG. 10 (j)). After that, the spare feeder 50D2 is replaced with the out-of-part feeder 50D1 according to the replacement guide. After replacement, parts will be supplied from the spare feeder 50D2 (FIG. 10 (k)). Here, too, the mounting control device 70 determines that a spare feeder 50A3 of the component type A, which is predicted to cause a component shortage next, is required, and displays a guide (preparation guide) for prompting the preparation of the spare feeder 50A3. Output to the operation panel 24. The operator sets the spare feeder 50A3 in the slot 62 immediately adjacent to the main area according to this guidance (FIG. 10 (k)). After that, in FIGS. 10 (k) to 10 (m), the transition is the same as in FIGS. 8 (k) to 8 (m). Even if the size of the sub-area of the feeder stand 60 is too small to set all the spare feeders 50 in the feeder stand 60 before processing the production job, the sub-area will be vacant after the replacement work. , The sub-region can be replenished by prompting the preparation of the spare feeder 50 as needed.

In the above-described embodiment, the mounting control device 70 provides a preparation-free guidance to the effect that the spare feeder 50 does not need to be prepared when the spare feeder 50 to be prepared is not required in the production job processing routine S250. It may be output to the display operation panel 24, and if there is no spare feeder 50 to be moved, a movement unnecessary guidance indicating that it is not necessary to move the spare feeder 50 set in the feeder stand 60 is displayed. It may be output to the panel 24. In this way, it is possible to avoid having the operator do unnecessary work.

In the above-described embodiment, the management computer 80 executes the pre-production job processing work routine, but the mounting control device 70 of the component mounting machine 20 may execute the pre-production job processing work routine. Further, although the mounting control device 70 executes the production job processing routine, the management computer 80 may execute the production job processing routine.

In the above-described embodiment, when various guides are displayed in the production job processing routine, they are displayed on the display operation panel 24, but they may be displayed on the display 82 or displayed on both the display operation panel 24 and the display 82. Alternatively, it may be displayed on a large display of a factory where the component mounting system 10 is installed.

In the above-described embodiment, in the production job processing routine of FIG. 7, the mounting control device 70 executes S250 to S258, but instead, proceeds to S240 and then S252 to display the exchange guide, and then proceeds to S260. May be good. Even in this way, the spare feeder 50 is not only temporarily used, but is finally moved to the main area and continues to be used. Therefore, it is not necessary to prepare a feeder 50 of a part type that has run out of parts separately from the spare feeder 50. Therefore, when a component shortage occurs during the processing of the production job, each component can be smoothly mounted on the substrate 12 in the same procedure as before the component shortage occurred. Alternatively, the mounting control device 70 determines whether or not there is a spare feeder 50 to be moved in S250, displays only the exchange guide if the determination is negative (S252), and displays the exchange guide if the determination is positive (S252). And the movement guidance may be displayed (S254). Alternatively, the mounting control device 70 determines whether or not there is a spare feeder 50 to be prepared in S250, displays only the exchange guide if it is a negative determination (S252), and displays only the exchange guide if it is an affirmative determination (S254). You may be willing to display the exchange guide and the preparation guide (S256).

In the above-described embodiment, the spare feeders 50A1, 50D1 of the part type that will be out of parts in the first and second times are set in the slot 62 immediately adjacent to the main area, and the remaining spare feeders 50A2, A3, B1, D2 May be randomly set in the empty slot 62. Even in this way, if the movement guide is displayed as needed and the operator resets the spare feeder 50 accordingly, the same effect as that of the above-described embodiment can be obtained.

In the above-described embodiment, when the parts are collected, the parts are attracted by the nozzle 44, but the parts are not particularly limited to the nozzle 44, and the parts may be grasped by a hand, for example. Further, in the above-described embodiment, the feeder 50 is adopted as the component supply unit, but the present invention is not particularly limited to the feeder 50, and for example, a tray may be adopted.

In the above-described embodiment, in S120 of the production job pre-processing work routine, it is determined whether or not the feeders 50 are set in all the slots 62 of the main area and the sub-area, but the feeders 50 are set in all the slots 62 of the main area. May be determined whether or not is set. This is because the spare feeder 50 in the sub region can start production even if it is not set. When the spare feeder 50 is not set in the sub area, the slot position of the spare feeder 50 to be set in the sub area is displayed on the display operation panel 24 or the like, so that after the start of production and before the parts run out. A spare feeder 50 may be set in the sub area according to the display.

The production job processing method of the present disclosure may be configured as follows.

In the production job processing method of the present disclosure, in the step (a), when the parts supply unit is set in the main area, the parts supply unit is arranged in a layout in which the production time per substrate is predicted to be the shortest. It may be set in the main area. In this way, the production job can be processed in a short time.

In the production job processing method of the present disclosure, in the step (a), when the spare parts supply unit is set in the sub-region, the spare parts supply unit of a part type that is predicted to run out of parts at an early timing. It may be set so as to be closer to the main area. In this way, it is possible to shorten the time required for the component transfer device to collect the components from the spare component supply unit of the component type that has run out of components and mount the components on the board. In such a production job processing method, in the step (b), when the replacement work is completed, the spare part supply unit of the part type that is predicted to be out of parts next is moved to the vicinity of the main area. A guide prompting the work may be output to the display device. In this way, when a part breaks out next time, the time required for the part transfer device to collect the part from the spare part supply unit of the part type that has run out and mount it on the board can be shortened. Can be done.

In the production job processing method of the present disclosure, in the step (b), when outputting the guidance prompting the replacement work to the display device, it is determined whether or not a further spare parts supply unit is necessary, and if necessary. For example, a guide prompting the preparation of the spare component supply unit may be output to the display device. In this way, for example, even if the size of the sub-area of the parts supply unit is too small to hold all the spare parts supply units in the parts supply unit before processing the production job, the sub-area is free after the replacement work. Therefore, it is possible to prompt the preparation of a spare parts supply unit and replenish the sub-region as needed. If no further spare parts supply unit is required, a guide indicating that preparation of the spare parts supply unit is not necessary may be output to the display device. In this way, it is possible to avoid having the operator do unnecessary work.
