Description

Production support equipment

This specification relates to a production support device applied to a parts mounting machine that can be used in combination with an auto-loading feeder and a manual loading feeder.

Technology for mass-producing board products by performing board-to-board work on boards with printed wiring is widespread. As a typical example of a board-to-board work machine that performs board-to-board work, there is a component-mounting machine that carries out component-mounting work. Many component mounting machines can be used in combination with an auto-loading feeder and a manual loading feeder that supply components using carrier tape. With the auto-loading feeder, it is possible to replenish the parts to insert the next carrier tape regardless of the number of remaining parts of the carrier tape currently in use. On the other hand, in the manual loading feeder, parts are replenished by splicing work to connect the next carrier tape shortly before the carrier tape is used up. Patent Document 1 discloses a technical example in which the above two types of feeders are used in combination.

The component type allocation optimization device disclosed in Patent Document 1 prioritizes the splicing operations obtained for each component type in descending order of frequency, and is an autoloading feeder in order from the component type with the highest priority. Allocate (assign) to. According to this, it is said that the auto-loading feeder can be effectively utilized to reduce the splicing work and further contribute to the improvement of the production efficiency of the substrate product.

International Publication No. 2016/142789

By the way, when using multiple manual loading feeders, the time to use up the carrier tape may approach each of the feeders. In this case, since the splicing work cannot be performed until the number of remaining parts is less than a certain level, a plurality of splicing works overlap (splicing rush), which may lead to production interruption due to parts shortage. Further, when the splicing work is not performed, the carrier tape insertion work becomes frequent. In either case, the operator is heavily burdened.

As an example of this measure, using an autoloading feeder together as exemplified in Patent Document 1 is effective for leveling work. Further, since the auto-loading feeder is more expensive than the manual loading feeder and the number of units owned is limited, the cost performance can be improved by preferentially using it. However, in the technique of Patent Document 1, the component type having a high priority is assigned to the autoloading feeder in consideration of the product type of the substrate product to be produced next, but it is not always optimized.

For example, even if a part type that is frequently used for the next product type is assigned to the autoloading feeder, it is not used at all for the next and subsequent product types, and the autoloading feeder may be suspended unnecessarily. be. Conversely, when a part type that is used less for the next product type is assigned to the manual loading feeder, it is used more for the next and subsequent product types and requires frequent splicing or insertion work. May become.

In addition, it is assumed that the production plan for board products is unknown in the first place. For example, the management department that centrally manages the product type, production quantity, delivery date, etc. of the board product and plans the production order and production schedule of the board product, the board production line to be used, etc., and the board according to the instructions from the management department. The production department that operates the production line may be a separate department. In this case, it becomes difficult to share the production plan because the information management system is different for each department, the information security management is restricted, or it takes time and effort. Moreover, even if the production plan can be shared, the plan change may occur or the notification of the plan change may be delayed.

On the other hand, the board production line often repeatedly produces board products of multiple product types. Alternatively, since each of the plurality of substrate production lines has the characteristics of each line, it is often the case that they are in charge of a plurality of similar substrate types that match the characteristics. Then, it is possible to properly assign the component type to the autoloading feeder used in the component mounting machine based on the past production results of the substrate product, not the future production plan of the substrate product.

Therefore, in the present specification, a production support device that enables effective use of the autoloading feeder by appropriately allocating a plurality of component types of parts to be mounted on the board to the autoloading feeder having a limited number of units. Is an issue to be solved.

The present specification allows the insertion work of inserting the second carrier tape into the insertion portion while using the first carrier tape holding a plurality of parts, and when the first carrier tape is used up. An autoloading feeder having an automatic loading function for sending the second carrier tape from the insertion section to the supply section and a manual loading feeder having no automatic loading function can be used in combination, and the component can be used as a substrate. It is a production support device applied to a component mounting machine that is mounted on a machine to produce a board product, and is a storage unit that stores the production record of producing the board product of a plurality of product types, and based on the production record. An aggregation unit that aggregates the number of used parts used in production for each part type, and an allocation unit that preferentially allocates the parts that are used in large numbers to the autoloading feeder for future production. Disclose a production support device equipped with.

In the production support device disclosed in this specification, the number of used parts used is totaled for each part type based on the production results of a plurality of product types, and the number of parts used is large for future production. Is preferentially assigned to the autoloading feeder. Here, the board production line and the component mounting machine often repeatedly produce board products of a plurality of product types, or are in charge of a plurality of similar product types. Therefore, there is a strong correlation between the number of parts used in the actual production and the number of parts used in future production. Therefore, it is possible to preferentially allocate the parts types that are estimated to be used in large numbers to the auto-loading feeders having a limited number of units, and it is possible to make effective use of the auto-loading feeders. As a result, there is a degree of freedom in the timing of performing the parts replenishment work, the work is leveled, and the workability is improved. In addition, the use of manual loading feeders is reduced, reducing splicing rushes and missing parts.

It is a side view which shows the configuration example of the auto-loading feeder. It is a block diagram which shows the functional structure of the production support apparatus of embodiment. It is a figure of the operation flow explaining the operation of a production support apparatus. It is a figure of the list which illustrates the part type assigned to the autoloading feeder by the operation of a production support apparatus, and the arrangement position of an autoloading feeder and a manual loading feeder. In the application example, it is the figure of the list which exemplifies the component type assigned to the autoloading feeder, and the arrangement position of an autoloading feeder and a manual loading feeder.

1. 1. Configuration of the component mounting machine 1 First, the configuration of the component mounting machine 1 to which the production support device 3 of the embodiment is applied will be described with reference to FIG. The direction from the right side to the left side of the paper surface in FIG. 1 is the X-axis direction in which the substrate K is carried in and out, and the direction from the rear on the lower side of the paper surface to the front on the upper side of the paper surface is the Y-axis direction. The component mounting machine 1 is configured by assembling a board transfer device 12, a detachable manual loading feeder 7, an autoloading feeder 9, a component transfer device 14, a component camera 15, a control device 16, and the like to a base 19. .. The component mounting machine 1 produces substrate products of a plurality of product types. The production support device 3 is not applied to the component mounting machine 1 in which the manual loading feeder 7 and the auto loading feeder 9 cannot be used together, or the component mounting machine 1 that produces only a board product of one product type for a long period of time.

The board transfer device 12 carries in the board K to the mounting implementation position, positions it, and carries it out. The substrate transfer device 12 includes a first guide rail 121 and a second guide rail 122, a pair of conveyor belts, a clamp device, and the like. The first guide rail 121 and the second guide rail 122 extend in the transport direction (X-axis direction) across the center of the upper surface of the base 19, and are assembled to the base 19 in parallel with each other. A pair of endless annular conveyor belts (not shown) are juxtaposed on the inside of the first guide rail 121 and the second guide rail 122 facing each other. The pair of conveyor belts rotate around with both edges of the substrate K placed on the conveyor transport surface, and carry in and out the substrate K to the mounting implementation position set in the central portion of the base 19. A clamp device (not shown) is provided below the mounting position. The clamping device pushes up the substrate K, clamps it in a horizontal posture, and positions it at the mounting implementation position. As a result, the component transfer device 14 can perform the mounting operation at the mounting implementation position.

The manual loading feeder 7 and the auto loading feeder 9 are formed in a flat shape having a small width direction dimension. The manual loading feeder 7 and the auto loading feeder 9 are arranged in the first slot SL1 to the ninth slot SL9, which are the arrangement positions (slot positions) on the common pallet 81 mounted on the base 19. The manual loading feeder 7 and the auto loading feeder 9 supply components using carrier tapes (85, 86) (see FIG. 2) holding a plurality of components.

In the example shown in FIG. 1, the auto-loading feeder 9 is arranged in the fourth slot SL4 and the fifth slot SL5, and the manual loading feeder 7 is arranged in the other slots (SL1 to SL3, SL6 to SL9). Behind the autoloading feeder 9, a reel holding device 82 that can be attached to and detached from the common pallet 81 is arranged. On the other hand, the manual loading feeder 7 may be provided with a reel holding portion integrally, or may be provided with a separate reel holding portion. The actual component mounting machine has a larger number of slots, and a larger number of feeders (7, 9) are arranged.

The parts transfer device 14 sucks and collects parts from the supply unit 94 (see FIG. 2) of the manual loading feeder 7 and the auto-loading feeder 9, transports them to the positioned substrate K, and mounts them. The component transfer device 14 is an XY robot type device that can move horizontally in the X-axis direction and the Y-axis direction. The component transfer device 14 includes a pair of Y-axis rails 141 and Y-axis rails 142, a Y-axis slider 143, an X-axis slider 144, a mounting head 145, a board camera 146, and the like. The Y-axis rail 141 and the Y-axis rail 142 are arranged near both side surfaces of the base 19, and extend in the front-rear direction (Y-axis direction). A Y-axis slider 143 is mounted on the upper side of the Y-axis rail 141 and the Y-axis rail 142 so as to be movable in the Y-axis direction. The Y-axis slider 143 is driven by the Y-axis ball screw mechanism (not shown).

The X-axis slider 144 is mounted on the Y-axis slider 143 so as to be movable in the X-axis direction. The X-axis slider 144 is driven by the X-axis ball screw mechanism (not shown). A mounting head 145 is provided on the rear side of the X-axis slider 144. The mounting head 145 has a nozzle tool having one suction nozzle or a plurality of suction nozzles on the lower side. The board camera 146 is provided on the X-axis slider 144 along with the mounting head 145. The board camera 146 captures an image of the fiducial mark attached to the board K and detects the exact position of the board K.

The component camera 15 is provided upward at the center position in the width direction of the upper surface of the base 19 between the board transfer device 12 and the feeders (7, 9). The component camera 15 captures the state of the component sucked by the suction nozzle while the mounting head 145 is moving from the feeder (7, 9) onto the substrate K. The image pickup data of the component camera 15 is image-processed, and an error in the suction posture of the component, a deviation in the rotation angle, and the like are detected. Based on the result of the image processing, the control device 16 finely adjusts the component mounting operation as necessary, and controls the disposal of the component when the mounting is difficult.

Here, the operating efficiency of the component mounting operation of the component transfer device 14 changes according to the array position (slot position) in which the feeders (7, 9) are arranged. More specifically, when the component is sucked from the feeder (7, 9) of the fifth slot SL5 closest to the component camera 15, the moving distance and moving time of the mounting head 145 are the smallest, and the operating efficiency is the highest. On the contrary, when the component is sucked from the first slot SL1 or the ninth slot SL9 farthest from the component camera 15, the operation efficiency is the lowest. Therefore, the fifth slot SL5 is the most advantageous in terms of the operating efficiency of the component transfer device 14, and hereinafter, the fourth slot SL4 and the sixth slot SL6, the third slot SL3 and the seventh slot SL7, the second slot SL2 and the second slot SL5 are the most advantageous. The 8-slot SL8, the 1st slot SL1 and the 9th slot SL9 are disadvantageous in this order.

The control device 16 holds mounting sequence data that specifies the component type, the number of mountings, the mounting position, the mounting order, the suitable suction nozzle, and the like of the parts to be mounted on the board K. The mounting sequence data differs depending on the product type of the board product. The control device 16 controls the component mounting operation according to the mounting sequence data based on the image pickup data of the board camera 146 and the component camera 15, the detection data of the sensor in the figure, and the like. The board transfer device 12, each feeder (7, 9), the component transfer device 14, and the component camera 15 perform predetermined operations according to the control from the control device 16. Further, the control device 16 sequentially collects and updates operating status data such as the number of produced board products, the mounting time required for mounting the components, and the number of occurrences of the component suction error.

2. 2. Configuration Example of Autoloading Feeder 9 Next, a configuration example of the autoloading feeder 9 and the reel holding device 82 will be described with reference to FIG. As shown, the common pallet 81 is detachably mounted on the upper side of the base 19. The common pallet 81 has a feeder mounting portion 811 and a reel mounting portion 815. The feeder mounting portion 811 is formed by providing an upright portion 813 on the front side of a substantially rectangular flat surface portion 812, and has a substantially L shape in a side view. The flat surface portion 812 is provided with nine first slot SL1 to nineth slot SL9 extending in the front-rear direction side by side in the width direction. The feeders (7, 9) are inserted and mounted from the rear of the slot toward the front upright portion 813.

The autoloading feeder 9 has an insertion portion 91 near the middle height of the rear end and an insertion lever 92 near the upper part of the rear end. By lifting the insertion lever 92, two carrier tapes (85, 86) can be inserted into the insertion portion 91 in order. A guide rail 93 is provided from the insertion portion 91 of the autoloading feeder 9 toward the upper part of the front end. The supply unit 94 is set on the upper surface near the front end of the guide rail 93. The standby position 96 is set on the upper surface of the guide rail 93 near the rear portion near the insertion portion 91.

A tape control unit 95 is provided above the standby position 96. The tape control unit 95 makes the second carrier tape 86 stand by at the standby position 96 while allowing the first carrier tape 85 to be sent out from the standby position 96. A specific configuration of the tape control unit 95 is disclosed in, for example, Japanese Patent Application Laid-Open No. 2014-82454. The autoloading feeder 9 further includes a tape feeding mechanism (not shown) composed of a servomotor, a sprocket, and the like. The tape feed mechanism feeds the first carrier tape 85 at a pitch toward the supply unit 94 along the guide rail 93, and supplies a plurality of parts in order.

In the auto-loading feeder 9, the insertion work of inserting the second carrier tape 86 into the insertion portion 91 is possible while the first carrier tape 85 is being used. Further, the auto-loading feeder 9 has an automatic loading function of sending the second carrier tape 86 from the insertion section 91 to the supply section 94 when the first carrier tape 85 is used up. Therefore, the splicing operation for connecting the first carrier tape 85 and the second carrier tape 86 is unnecessary. Further, the time for inserting the second carrier tape 86, in other words, the time for carrying out the parts supply work may be immediately after the first carrier tape 85 is inserted, or the production with the first carrier tape 85 is performed. It may be at any time during the process.

The reel mounting portion 815 of the common pallet 81 is composed of two arm members 816, a front transfer plate 817, a rear transfer plate 818, and the like. The two arm members 816 are formed so as to extend horizontally rearward from both sides of the feeder mounting portion 811, subsequently inclined backward and downward, and further extend horizontally rearward. The advance payment plate 817 is passed so as to connect the inclined portions of the two arm members 816. A post-delivery plate 818 is passed so as to connect the horizontal portions behind the two arm members 816. One or more reel holding devices 82 are detachably equipped on the upper side of the front transfer plate 817 and the rear transfer plate 818.

The reel holding device 82 rotatably holds the first reel 83 on the front side and rotatably holds the second reel 84 on the rear side. The first carrier tape 85 is pulled out from the first reel 83, and the second carrier tape 86 is pulled out from the second reel 84. The reel holding device 82 is not limited in size in the width direction (direction of the reel axis), and holds one or a plurality of reels (83, 84) side by side in the width direction. Therefore, the reel holding device 82 corresponds to one or a plurality of autoloading feeders 9 and is mounted behind the reel holding device 82.

On the other hand, the manual loading feeder 7 uses one reel. Before the manual loading feeder 7 runs out of the first carrier tape, the operator needs to prepare a new reel and perform a splicing operation for connecting the first carrier tape and the second carrier tape. If the splicing operation is not performed, the manual loading feeder 7 runs out of the first carrier tape and runs out of parts.

In this case, the operator subsequently inserts the second carrier tape into the insertion portion of the manual loading feeder 7. Then, the manual loading feeder 7 performs a loading operation of sending the second carrier tape from the insertion section to the supply section. The time when the splicing work and the insertion work should be performed is limited by the progress of the component mounting operation, so that the workability is not good. Since the manual loading feeder 7 can have a configuration disclosed in various publicly known techniques, detailed description thereof will be omitted.

The auto-loading feeder 9 is a new model that was commercialized later than the manual loading feeder 7, and is more expensive than the manual loading feeder 7. Therefore, the number of auto-loading feeders 9 owned is limited. On the other hand, the number of manual loading feeders 7 owned is sufficient. If the number of autoloading feeders 9 equal to or larger than the total number of slots of the component mounting machine 1 is always available, it is not necessary to apply the production support device 3.

3. 3. Configuration of Production Support Device 3 of the Embodiment Next, the configuration of the production support device 3 of the embodiment will be described with reference to FIG. The production support device 3 is configured by using a computer device. The production support device 3 may be a part of the control device 16 described above, or may be formed separately from the control device 16 and connected to the control device 16 by communication. The production support device 3 has an input unit and a display unit as a man-machine interface. Further, the production support device 3 includes four functional units realized by software, that is, a storage unit 41, an aggregation unit 42, an allocation unit 43, and an arrangement determination unit 44. The four functional units operate at the setup change timing for changing the product type of the board product produced by the component mounting machine 1, and do not operate during the production of the product type.

The storage unit 41 operates every time the setup change time comes. The storage unit 41 sequentially stores the production results of the substrate products most recently produced by the component mounting machine 1. The production record includes at least data on the production order, product type, and number of production pieces of the substrate product. The production record is stored in the database 45, for example. The database 45 also stores mounting sequence data that differs for each product type. The storage unit 41 may store the production plan of at least one or more product types of the substrate products to be produced in the future, in addition to the past production results. The production plan data is transferred from another computer device or input from the input unit by the operator.

The tabulation unit 42 operates following the storage unit 41 at some of the setup change timings. The totaling unit 42 totals the number of parts used for production for each part type based on the production results. This tabulation is performed using the data of the product type and the number of production pieces included in the production record in the database 45, and the data of the number of pieces mounted (the number of pieces mounted per board product) for each component type included in the mounting sequence data. be able to. The totaling unit 42 sets the latest predetermined period as the totaling period and performs totaling. The tabulation unit 42 can appropriately set a predetermined period according to the frequency of occurrence of the setup change time.

For example, if multiple setup changes occur in a day, the predetermined period is set to one day. In addition, if one setup change period occurs within a few days or a week, the predetermined period is set to January. As shown in these examples, the predetermined period preferably includes the production period of a plurality of product types. The predetermined period is not limited to the above example, and the predetermined period may be one week or March, and the setting may be variably changed. Further, the predetermined period may be set by using the number of production sheets of the substrate product in addition to setting by using the time. The tabulation operation of the tabulation unit 42 is performed to estimate the types of parts that are frequently used in future production.

Here, the component mounting machine 1 often repeatedly produces board products of a plurality of product types. Alternatively, the component mounting machine 1 is often in charge of a plurality of similar substrate types that match the performance and characteristics possessed by the component mounting machine 1. For example, in a plurality of similar substrate types, the majority of the component types mounted on the substrate K match, and only a small part of the component types differ. Therefore, there is a strong correlation between the number of parts used in the actual production and the number of parts used in future production. Therefore, even if the future production plan of the substrate product is unknown, the tabulation unit 42 can estimate the parts type that will be used frequently in the future with reference to the past production results of the substrate product.

Further, when the storage unit 41 stores the production plan, the aggregation unit 42 may set an aggregation period other than the latest by referring to the production plan. In other words, the tabulation unit 42 can tabulate the number of parts used for each part type based on the production results including the product types included in the production plan. Supplementally, since the product types commonly included in the production results and the production plan are the repeat product types that are repeatedly produced, the aggregation unit 42 aggregates the repeat product types. According to this, the tabulation unit 42 can estimate the parts that will be used frequently in the future with high accuracy.

The allocation unit 43 operates following the aggregation unit 42. The allocation unit 43 preferentially allocates the parts type having a large number of used aggregate results of the aggregation unit 42 to the autoloading feeder 9 for future production. The result assigned by the allocation unit 43 is applied until the aggregation unit 42 performs the next aggregation, and in many cases, it is applied to a plurality of future product types. Further, the allocation unit 43 also uses the manual loading feeder 7 only when the number of autoloading feeders 9 that can be used is insufficient for the number of types of parts.

The sequence determination unit 44 operates following the allocation unit 43. The arrangement determination unit 44 arranges the auto-loading feeder 9 and the manual loading feeder 7 in the component mounting machine 1 based on the number of parts used assigned to each of the auto-loading feeder 9 and the manual loading feeder 7. Determine the slot position). The result determined by the sequence determination unit 44 is applied until the aggregation unit 42 performs the next aggregation. Further, the sequence determination unit 44 fixes the sequence position of the autoloading feeder 9 to a plurality of product types of substrate products to be produced in the future. The functions and operations of the storage unit 41, the aggregation unit 42, the allocation unit 43, and the sequence determination unit 44 will be described with reference to specific examples in the following description of the operation.

4. Operation of Production Support Device 3 Next, the operation of the production support device 3 of the embodiment will be described with reference to FIGS. 4 and 5. The operation flow of the production support device 3 shown in FIG. 4 is repeatedly executed during the operation of the component mounting machine 1. Further, the list of FIG. 5 shows an example of the result of executing the operation flow. The left side of FIG. 5 shows the production results stored by the storage unit 41, and the right side of the double vertical line shows the operation results of the tabulation unit 42, the allocation unit 43, and the arrangement determination unit 44. Further, the number of mounted parts for each component type per board product is data included in the mounted sequence data. It is assumed that the storage unit 41 does not store the future production plan.

In step S1 of FIG. 4, the production support device 3 determines whether or not it is time to change the setup for changing the product type of the board product produced by the component mounting machine 1. If it is in the middle of production of a certain product type and it is not the time for setup change, the production support device 3 immediately ends the operation flow. When it is time to change the setup, the production support device 3 advances the execution of the operation flow to step S2.

In step S2, the storage unit 41 stores the production results of the board product most recently produced by the component mounting machine 1. In the example of FIG. 5, step S2 has already been executed eight times or more, and the production results are shown using the production sequences 1 to 8 of the substrate products. Production sequence 1 is the oldest and production sequence 8 is the latest and newest. In

production order

1, 100 substrate products of product type A are produced. The number of parts mounted per board product of the product type A is four for the part type P1, two for the part type P2, one for the part type P3, and one for the part type P4. Further, in the production sequences 2 to 8, the substrate products of product types B, C, D, A, B, C, and E are produced, respectively, and the number of products produced and the number of mounted products for each component type are as shown in FIG. ..

In the next step S3, the tabulation unit 42 determines whether or not a predetermined elapsed period has elapsed since the execution of the previous steps S4 to S7. Here, it is assumed that the predetermined elapsed period is set shorter than the predetermined period (aggregation period) in which the aggregation unit 42 aggregates. Not limited to this, the predetermined elapsed period and the aggregation period for performing aggregation can be set independently, and the magnitude relationship between the two is not limited. If the predetermined elapsed period is set to be too small, the feeder (7, 9) replacement work or the arrangement position change work will be performed at many setup change times, which increases the labor and complexity of the work. On the contrary, if the predetermined elapsed period is set excessively, some product types cannot be produced due to a shortage of parts in the middle of the elapsed period.

In the present embodiment, it is assumed that steps S4 to S7 are executed at the setup change time after the production sequence 5, and the feeder (7, 9) replacement work or the arrangement position change work is performed. Further, it is assumed that the elapsed time has not yet elapsed in the setup change time after the

production sequences

6 and 7, and the elapsed time has elapsed in the setup change time after the production sequence 8. In this case, the tabulation unit 42 ends the operation flow following the execution of step S3 at the setup change time after the

production sequences

6 and 7. Further, the tabulation unit 42 advances the execution of the operation flow from step S3 to step S4 at the setup change time after the production sequence 8.

In step S4, the aggregation unit 42 aggregates the production sequences 5 to 8 corresponding to the latest predetermined period as the aggregation period. In the example of FIG. 5, the totaling unit 42 uses 4 pieces × 100 for the product type A of the

production order

5, 1 piece × 50 for the product type B of the production order 6, and the product of the production order 7 as the number of parts used in the part type P1. Add 2 pieces x 50 for the seed C and 0 pieces for the product type E of the production order 8 to obtain 550 pieces. By the same calculation, the tabulation unit 42 uses 250 parts type P2, 150 parts type P3, 100 parts type P4, 230 parts type P5, and parts P6. The number of used parts is 180, the number of used parts of the part type P7 is 130, and the number of used parts of the part type P8 is 130.

In the next step S5, the allocation unit 43 acquires the number of usable autoloading feeders 9. The number of units that can be used is from all the auto-loading feeders 9 that are in use in other parts mounting machines, those that do not meet the specifications such as the width dimension of the carrier tape (85, 86), and those that are used for maintenance or failure. It is the number after deducting the things that cannot be done. Therefore, the number of units that can be used varies from time to time. Hereinafter, it is assumed that the number of usable units is four.

In the next step S6, the allocation unit 43 preferentially allocates the component types having a large number of usages of the aggregation result of the aggregation unit 42 to the autoloading feeder 9. In the example of FIG. 5, the allocation unit 43 allocates the component type P1, the component type P2, the component type P5, and the component type P6 to the four autoloading feeders 9 in descending order of the number of uses (the ALF allocation in FIG. 5). (Indicated by 〇 in the column). Here, while the number of parts types P1 to P8 is eight, there are only four autoloading feeders 9 that can be used, which is insufficient.

Therefore, the allocation unit 43 also uses the manual loading feeder 7. Specifically, the allocation unit 43 allocates the remaining part type P3, part type P4, part type P7, and part type P8 to the manual loading feeder 7. If there are eight autoloading feeders 9 that can be used, the allocation unit 43 uses all the autoloading feeders 9 and does not use the manual loading feeder 7 together.

In the next step S7, the arrangement determination unit 44 determines the arrangement position (slot position) of the feeders (7, 9) based on the number of parts used assigned to each of the plurality of feeders (7, 9). do. In the example of FIG. 5, the arrangement determination unit 44 determines the arrangement position of the autoloading feeder 9 of the component type P1 most frequently used in the most advantageous fifth slot SL5. Further, the arrangement determination unit 44 sets the arrangement position of the auto-loading feeder 9 of the component type P2, the component type P5, and the component type P6, which are the second to fourth most used, in the fourth slot SL4, the fourth slot SL4, which is relatively advantageous. The 6-slot SL6 and the 3rd slot SL3 are determined.

On the other hand, the arrangement determination unit 44 sets the arrangement position of the manual loading feeder 7 of the part type P3, the part type P7, the part type P8, and the part type P4, which is the 5th to 8th least used, at a relatively disadvantageous seventh position. The slot SL7, the second slot SL2, the eighth slot SL8, and the first slot SL1 are determined. The allocation result of the allocation unit 43 and the determination result of the arrangement determination unit 44 are displayed on the display unit. This ends the operation flow.

The operator confirms the displayed contents and performs the setup change work of the feeder (7, 9). After that, the component mounting machine 1 produces the substrate products of the next and subsequent product types. Here, since the parts type that are estimated to be used frequently in the future are assigned to the auto-loading feeder 9, the degree of freedom is given to the timing of inserting the second carrier tape 86, and the workability is improved. .. Further, since the parts type that are estimated to be used less in the future are assigned to the manual loading feeder 7, the number of splicing operations is reduced.

Furthermore, since all of the available autoloading feeders 9 can be effectively used, cost performance is improved. In addition, since the auto-loading feeder 9 to which the component types estimated to be used in the future are assigned is arranged at an advantageous arrangement position (slot position), the moving distance and moving time of the mounting head 145 that performs the component mounting operation. Becomes smaller. As a result, the operating efficiency of the component transfer device 14 can be increased.

The arrangement positions (SL3 to SL6) of the four autoloading feeders 9 are fixed to a plurality of product types of substrate products to be produced in the future. According to this, the setup change work for changing the arrangement position (SL3 to SL6) of the autoloading feeder 9 becomes unnecessary at the setup change time before the totalization unit 42 performs the next totalization. If production of a peculiar product type that is not in the production record is planned and production cannot be performed with the set-up feeders (7, 9), the operator handles it by the setup change work of the manual loading feeder 7.

In the production support device 3 of the embodiment, the number of used parts used is totaled for each part type (P1 to P8) based on the production results of a plurality of product types (A to E), and future production is targeted. As a result, the parts types (P1, P2, P5, P6) that are frequently used are preferentially assigned to the autoloading feeder 9. Here, the substrate production line or the component mounting machine 1 often repeatedly produces substrate products of a plurality of product types (A to C), or is in charge of a plurality of similar product types. Therefore, there is a strong correlation between the number of parts used in the actual production and the number of parts used in future production. Therefore, the parts types (P1, P2, P5, P6) that are estimated to be used in large numbers in the future can be preferentially assigned to the autoloading feeder 9 having a limited number of units, and the autoloading feeder 9 can be assigned preferentially. Can be effectively used. As a result, there is a degree of freedom in the timing of performing the parts replenishment work, the work is leveled, and the workability is improved.

Furthermore, the use of the manual loading feeder 7 is suppressed. Specifically, the manual loading feeder 7 is used together only when the number of auto-loading feeders 9 is insufficient, and the number of parts to be used in the future is estimated to be small (P3, P4, P7, P8). Is assigned. Therefore, the number of splicing operations is reduced, and splicing rushes and parts shortages are reduced.

5. Application example of operation Next, an application example of the operation of the production support device 3 of the embodiment will be described with reference to FIGS. 5 and 6. In the application example, the storage unit 41 stores a production plan that "the product types A, B, and C will be produced in order in the future, but the number of each product is undecided at the present time" at the setup change time after the production order 8. are doing. In this case, the tabulation unit 42 can set a tabulation period other than the latest by referring to the production plan. In the production results shown in FIG. 5, the results of producing the product types A, B, and C in order as in the production plan exist in the production orders 1 to 3 and the production orders 4 to 7. That is, product types A, B, and C correspond to repeat product types. Therefore, the aggregation unit 42 aggregates the repeat product types.

Specifically, in step S4 of the operation flow, the totaling unit 42 totals the product types A, B, and C of the production orders 5 to 7 as the totaling period at the setup change time after the production order 8. That is, as shown in FIG. 6, the totaling unit 42 uses 0 parts for the product type A of the

production order

5, 2 pieces × 50 for the product type B of the production order 6, and the production order 7 as the number of parts used in the part type P5. Add 1 piece x 50 for the product type C of the above to obtain 150 pieces. By the same calculation, the tabulation unit 42 uses 550 parts type P1, 250 parts type P2, 150 parts type P3, 100 parts type P4, and parts P6. The number of used parts is 100, the number of used parts of the part type P7 is 50, and the number of used parts of the part type P8 is 50.

In the next step S5, the allocation unit 43 acquires that the number of usable autoloading feeders 9 is four. In the next step S6, the allocation unit 43 allocates the part type P1, the part type P2, the part type P3, and the part type P5 to the autoloading feeder 9 in descending order of the number of uses (○ in the ALF allocation column of FIG. 6). (Indicated by). Further, the allocation unit 43 allocates the remaining part type P4, part type P6, part type P7, and part type P8 to the manual loading feeder 7.

In the next step S7, the arrangement determination unit 44 determines the arrangement position of the autoloading feeder 9 of the component type P1 that is used most frequently in the most advantageous fifth slot SL5, as shown in FIG. Further, the arrangement determination unit 44 arranges the arrangement positions of the part type P2, the part type P3, and the autoloading feeder 9 of the part type P5, which are the second to fourth most used, in the fourth slot SL4, the fourth slot SL4, which is relatively advantageous. The 6-slot SL6 and the 3rd slot SL3 are determined.

On the other hand, the arrangement determination unit 44 sets the arrangement position of the manual loading feeder 7 of the part type P4, the part type P6, the part type P7, and the part type P8, which is the 5th to 8th least used, at a relatively disadvantageous seventh position. The slot SL7, the second slot SL2, the eighth slot SL8, and the first slot SL1 are determined. The allocation result of the allocation unit 43 and the determination result of the arrangement determination unit 44 shown in FIG. 6 are different from those in FIG.

According to the application example, the aggregation unit 42 excludes the product type E of the production order 8 having a high contingency, and sets the repeat product type of the production order 5 to 7 as the aggregation period, so that the unit is frequently used in the future. The variety can be estimated with high accuracy. As a result, the effect that the workability is improved by the auto-loading feeder 9 and the effect that the number of splicing operations is reduced by the manual loading feeder 7 are ensured. Further, the effect that the auto-loading feeder 9 can be effectively used and the effect of increasing the operation efficiency of the component transfer device 14 are ensured.

6. Applications and Modifications of the Embodiment The configurations of the component mounting machine 1 and the autoloading feeder 9 can be variously modified. Further, the sequence determination unit 44 may be omitted. In this case, the determination of the arrangement positions of the plurality of feeders (7, 9) is performed by another software or by an operator. The present embodiment and application examples can be applied and modified in various ways.
