Embodiments for Carrying Out the Invention

[0010] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. The configurations, shapes, etc. described below are illustrative examples for explanation, and can be appropriately changed according to the specifications of the implementation system, production line, management computer (production support device), component mounting device, etc. In the following, corresponding elements in all the drawings are denoted by the same reference numerals, and duplicate explanations are omitted. In FIG. 1 and in part of the description below, as two axes orthogonal to each other in the horizontal plane, the X-axis in the substrate conveyance direction (the left-right direction in FIG. 1) and the Y-axis orthogonal to the substrate conveyance direction (the up-down direction in FIG. 1) are shown. In FIG. 2 and in part of the description below, the Z-axis (the up-down direction in FIG. 2) is shown as the height direction orthogonal to the horizontal plane.

[0011] First, referring to FIG. 1, the configuration of the mounting system 1 will be described. The mounting system 1 is configured such that three production lines L1 to L3 arranged on the floor F are connected by a communication network 2 by wire or wirelessly and are managed by a management computer 3. The production lines L1 to L3 are arranged in a production area Ap provided on the floor F. Each of the production lines L1 to L3 is configured by connecting a plurality of production devices including a printing device and a component mounting device as described later, and has a function of producing a mounted substrate obtained by mounting components on a substrate. Note that the number of production lines L1 to L3 included in the mounting system 1 does not have to be three, and may be one, two, or four or more.

[0012] In a preparation area As different from the production area Ap provided on the floor F, a placement work support device 4 is arranged. The placement work support device 4 is connected to a management computer 3 via a communication network 2. A replacement cart 5 that is the target of the placement work described later is connected to the placement work support device 4. In the preparation area As, a plurality of carts 5 in various states, such as before, during, or after the execution of the placement work, are stored. Further, in the preparation area As, elements detachable from production devices, such as a plurality of screen masks, feeders 12, mounting heads 15, suction nozzles 16, and reels 14 (see FIG. 2) used in the production devices arranged on the floor F, are stored.

[0013] In FIG. 1, for the cart 5 connected to the placement work support device 4, placement work is performed according to a work instruction corresponding to the types of mounting substrates to be produced on the production lines L1 to L3. The operator executes operations such as removing (removing) a plurality of feeders 12 and reels 14 that supply components as placement work from the cart 5, and attaching (attaching) them to the cart 5. For the replacement cart 5 in the preparation area As including the cart 5 connected to the placement work support device 4, placement work can be executed in parallel with the production of the mounting substrates on the production lines L1 to L3. Hereinafter, the preparation work for changing the type outside the production lines L1 to L3, including the placement work for the replacement cart 5, is referred to as external setup. Note that the operator includes work devices such as robots that execute work other than humans.

[0014] When changing the types of mounting substrates produced on the production lines L1 to L3, the operator moves the replacement cart 5 for which the placement work has been completed in the preparation area As to the production lines L1 to L3 and executes a type switching operation (replacement) to replace the cart 5 mounted on the component mounting device. Also, in the type switching operation, the operator moves the replacement screen mask, feeder 12, mounting head 15, suction nozzle 16, reel 14, etc. stored in the preparation area As to the production lines L1 to L3 and replaces them. Hereinafter, the preparation work for changing the type within the production lines L1 to L3, including the type switching operation for replacing the cart 5, is referred to as internal setup.

[0015] Next, referring to FIG. 1, the detailed configuration of production lines L1 to L3 will be described. The production lines L1 to L3 have the same configuration. Hereinafter, the production line L1 will be described. The production line L1 is configured by serially connecting production apparatuses such as a printing apparatus M1, component mounting apparatuses M2 to M5, and a reflow apparatus M6 in order from the upstream (left side of the paper surface) to the downstream (right side of the paper surface) in the substrate conveyance direction. The production apparatuses are connected to a management computer 3 via a communication network 2. Note that the production line L1 is a group of production apparatuses connected via the communication network 2, and the production apparatuses do not necessarily need to be physically connected to each other.

[0016] In FIG. 1, the printing apparatus M1 has a function of printing paste-like solder on a substrate through a screen mask. The component mounting apparatuses M2 to M5 have a function of picking up components supplied from a component supply unit by suction nozzles 16 attached to a mounting head 15 and transferring and mounting them on the mounting points of the substrate on which the cream solder is printed. The reflow apparatus M6 has a function of heating the substrate on which the components are mounted, melting the cream solder, and then solidifying it to solder the components to the substrate.

[0017] The management computer 3 executes processes such as production management of the mounting substrates manufactured in the production lines L1 to L3, creation, download, etc. of programs and data necessary for manufacturing the mounting substrates for each production apparatus. Further, the management computer 3 functions as a production support apparatus that supports the production of mounting substrates of a plurality of types by the production apparatuses such as creation of a production plan.

[0018] Next, referring to FIG. 2, the configuration of the component mounting apparatuses M2 to M5 will be described. Component supply units 11 are provided on the front side and the rear side of the component mounting apparatuses M2 to M5, respectively. In the component supply unit 11, a cart 5 having a plurality of slots arranged in parallel and a feeder base 13 on which a feeder 12 is mounted in each slot is disposed at the upper part. In the cart 5, a plurality of reels 14 for winding and storing a carrier tape for storing components are held in parallel below the feeder 12. The feeder 12 sequentially supplies the components stored in the carrier tape to the component mounting apparatuses M2 to M5 while conveying the carrier tape drawn out from the reel 14 inside.

[0019] Inside the component mounting apparatuses M2 to M5, a mounting head 15 equipped with a suction nozzle 16 for holding components is disposed. The mounting head 15 is moved between the component supply unit 11 and a substrate held at the mounting operation position by a lane for conveying the substrate by a head movement mechanism (not shown). Thereby, a component mounting operation for mounting the component taken out by the suction nozzle 16 from the feeder 12 of the component supply unit 11 to the mounting position of the substrate is executed. The detachable feeder 12, the cart 5 on which the feeder 12 is mounted, the suction nozzle 16, and the mounting head 15 on which the suction nozzle 16 is mounted are elements that are attached to and detached from the component mounting apparatuses M2 to M5 which are production apparatuses for use.

[0020] Next, referring to FIG. 3, the configuration of the information processing system of the management computer 3 will be described. Here, among the plurality of functions provided in the management computer 3, the configuration regarding the function as a production support apparatus for calculating and displaying the number of uses of the detachable elements in the production apparatuses included in the production lines L1 to L3 will be described.

[0021] The management computer 3 includes an input unit 31, a display unit 32, and a communication unit 33 in addition to a processing device 20 and a storage unit 25 which is a storage device. The processing device 20 is a data processing device such as a CPU, and includes an acquisition unit 21, a production plan creation unit 22, a usage quantity calculation unit 23, and a display processing unit 24 as internal processing units. The storage unit 25 stores substrate information 26, device information 27, component information 28, production plan information 29, component usage quantity information 30, and the like. Note that the management computer 3 does not necessarily have to be composed of a single computer, and may be composed of a plurality of devices. For example, all or part of the storage unit 25 and the processing device 20 may be provided in the cloud.

[0022] In FIG. 3, the input unit 31 is an input device such as a keyboard, a touch panel, or a mouse, and is used when an operation command or data is input. The display unit 32 is a display device such as a liquid crystal panel, and displays various data stored in the storage unit, and also displays various information such as an operation screen and an input screen for the operation by the input unit 31. The communication unit 33 is a communication interface, and performs data transmission and reception with production devices (printing device M1, component mounting devices M2 to M5) that constitute the production lines L1 to L3 via the communication network 2.

[0023] The acquisition unit 21 acquires the substrate information 26, device information 27, and component information 28 used for calculating the usage quantity of components from a production management device or a production database (not shown) and stores them in the storage unit 25. The substrate information 26 includes information for specifying the type for each type of mounting substrate, the size of the substrate, the mounting position of components, the type of components, the supply mode of components (width of carrier tape, tray, stick, etc.), information on the suction nozzle 16 corresponding to the components, and information on the mounting substrate such as the number of production sheets.

[0024] In FIG. 3, the device information 27 includes information for identifying the production facilities provided for each of the production lines L1 to L3, and information regarding the production devices such as the specifications of the production facilities. For example, the specifications of the component mounting devices M2 to M5 include the number and types of the carts 5 that can be mounted, the number and types of the mounting heads 15 that can be mounted, the number of lanes for transporting the substrates, the production capacity (such as the number of components that can be mounted on the substrate per unit time), and the like.

[0025] The element information 28 includes information for identifying elements, information regarding elements such as the specifications of the elements, for each type of element that can be attached to and detached from the production device. For example, the specifications of the cart 5 include the number and types of the feeders 12 that can be mounted. The specifications of the feeder 12 include the width of the carrier tape that can be supplied. The specifications of the mounting head 15 include the number and types of the suction nozzles 16 that can be mounted.

[0026] Here, with reference to FIG. 4, an example of some of the information included in the substrate information 26 will be described. The substrate information 26 stores the production quantity 42 of the mounting substrates for each product number 41 that identifies the product type of the mounting substrates. For example, the production quantity 42 of the mounting substrate with the product number 41 being "X1" (hereinafter referred to as "product X1", etc.) is "250 sheets". In this example, the substrate information 26 includes information related to 9 types of mounting substrates from product X1 to product X9.

[0027] In FIG. 3, based on the substrate information 26, the device information 27, and the element information 28, the production plan creation unit 22 creates a plurality of production plans for producing a plurality of types of mounting substrates, and stores them in the storage unit 25 as the production plan information 29. The production plan creation unit 22 includes a first processing unit 22a, a second processing unit 22b, and a third processing unit 22c that each create different production plans as internal processing units. The first processing unit 22a, based on the substrate information 26, the device information 27, and the element information 28, allocates a plurality of types to the production lines L1 to L3 without considering the production quantity 42 of the mounting substrates, and creates a production plan that performs a setup change for replacing the elements mounted on the production device every time the product type is changed.

[0028] Referring to FIG. 5 here, an example of a first production plan created by the first processing unit 22a to produce a mounting substrate in a plurality of production lines L1 to L3 arranged on the floor F shown in FIG. 1 included in the apparatus information 27 based on the substrate information 26 shown in FIG. 4 will be described. The first processing unit 22a assigns product types X1, X2, and X3 to production line L1, product types X4, X5, and X6 to production line L2, and product types X7, X8, and X9 to production line L1. Then, the first processing unit 22a creates a first production plan that executes a setup change every time the product type is changed.

[0029] Specifically, when producing product type X1, the first processing unit 22a creates a first production plan in which only the feeders 12 necessary for the production of product type X1 are mounted on the component mounting apparatuses M2 to M5 of production line L1. Also, when switching production line L1 from product type X1 to product type X2, the first processing unit 22a executes a setup change and creates a first production plan in which only the feeders 12 necessary for the production of product type X2 are mounted on the component mounting apparatuses M2 to M5. In this way, the first processing unit 22a creates a first production plan with the fewest number of uses of elements such as the feeders 12 and the carts 5 without considering the productivity and the number of setup changes of production lines L1 to L3.

[0030] In FIG. 3, the second processing unit 22b of the production plan creation unit 22 groups product types with high similarity of components of the mounting substrate as a group based on the substrate information 26, the apparatus information 27, and the element information 28, and creates a production plan for allocating a plurality of product types to the production lines L1 to L3 without considering the production number 42 of the mounting substrate. At that time, the second processing unit 22b creates a production plan that does not execute a setup change for a product type change within a group, and executes a setup change for a product type change between groups, a product type change between a group and another product type, and a product type change between product types outside the group.

[0031] Referring to FIG. 6 here, an example of the second production plan created by the second processing unit 22b to produce the mounting substrate in the plurality of production lines L1 to L3 arranged on the floor F shown in FIG. 1 included in the device information 27 based on the substrate information 26 shown in FIG. 4 will be described. The second processing unit 22b groups variety X1 and variety X8 into one group, and groups variety X4, variety X5, and variety X2 into one group. Then, the second processing unit 22b allocates the group of variety X1 and variety X8, variety X3 to production line L1, the group of variety X4, variety X5, and variety X2 to production line L2, and variety X6, variety X7, and variety X9 to production line L3.

[0032] And the second processing unit 22b does not perform setup change between variety X1 and variety X8 in the same group, between variety X4 and variety X5 in the same group, and between variety X5 and variety X2, and creates a second production plan that performs setup change between the group of variety X1 and variety X8 and variety X3, between variety X6 and variety X7, and between variety X7 and variety X9.

[0033] Specifically, the second processing unit 22b creates a second production plan in which all of the feeders 12 necessary for the production of variety X4, variety X5, and variety X2 are commonly arranged in the component mounting devices M2 to M5 of production line L2 so that no setup change occurs between variety X4, variety X5, and variety X2 in the same group. Also, when the second processing unit 22b switches production line L1 from the group of variety X1 and variety X8 to variety X3, it creates a second production plan in which only the feeders 12 necessary for the production of variety X3 are mounted on the component mounting devices M2 to M5 of production line L1.

[0034] In this way, the second processing unit 22b creates a second production plan that reduces the number of setup times in consideration of the similarity of the components of the mounting substrate and minimizes the number of uses of some elements such as the cart 5. In the second production plan, since the feeders 12 necessary for the production of a plurality of varieties are commonly arranged, the number of feeders 12 used is more than that in the first production plan.

[0035] In FIG. 3, the third processing unit 22c of the production plan creation unit 22 simulates the production of mounting substrates of a plurality of product types by the production apparatus based on the substrate information 26, the apparatus information 27, and the element information 28, and creates a production plan based on the result of the simulation. Specifically, the third processing unit 22c simulates the operations of production apparatuses such as component mounting apparatuses M2 to M5 based on the mounting positions of components to be mounted on the mounting substrate and the specifications of the production apparatus, and calculates the production time by multiplying the cycle time required to produce one mounting substrate by the number of mounting substrates to be produced 42.

[0036] For example, in the simulation of the component mounting apparatuses M2 to M5, the third processing unit 22c simulates operations such as the conveyance of the substrate by the lane, the supply of components by the feeder 12, the holding of components by the suction nozzle 16, and the transfer of components to the substrate by the mounting head 15 to calculate the cycle time. Further, the third processing unit 22c also simulates the occurrence of delays in the component mounting operation due to work mistakes, such as the probability of occurrence of work mistakes such as suction mistakes where the suction nozzle 16 in the component mounting apparatuses M2 to M5 cannot hold the component, and delays in the component replenishment operation to the feeder 12 due to a shortage of workers, and calculates the production time based on the occurrence of stoppages in the component mounting operations of the component mounting apparatuses M2 to M5.

[0037] In addition, the third processing unit 22c calculates the time required for the external setup of removing the unnecessary feeder 12 and reel 14 from the replacement cart 5 in the preparation area As and attaching the feeder 12 and reel 14 to be used for the next production based on the production order and the production time of the mounting substrate, and creates a setup plan including the external setup in the preparation area As and the internal setup (batch replacement) in the production lines L1 to L3.

[0038] In addition to the batch changeover for replacing the carriage 5 attached to the component mounting apparatuses M2 to M5 with the replacement carriage 5 prepared in the preparation area As, the third processing unit 22c also creates a setup plan that includes in-line setup by replacing a part of the feeders 12 and reels 14 attached to the component mounting apparatuses M2 to M5. Thus, the third processing unit 22c of the production plan creation unit 22 simulates the production of mounting substrates of a plurality of product types by the production apparatuses, and creates a production plan including a setup plan based on the result of the simulation.

[0039] Here, referring to FIG. 7, an example of the third production plan created by the third processing unit 22c to produce a mounting substrate in the plurality of production lines L1 to L3 arranged on the floor F shown in FIG. 1 included in the apparatus information 27 based on the substrate information 26 shown in FIG. 4 will be described. In this example, the third processing unit 22c groups product types with a high degree of similarity of components of the mounting substrate and then executes the simulation.

[0040] The created groups, the allocation to the production lines L1 to L3, and the production order are the same as those of the second production plan shown in FIG. 6. That is, the number of setup times is the same as that of the second production plan. The production time of each product type is calculated based on the result of the simulation, and the production time varies for each product type. Also, when the off-line setup work of the replacement carriage 5 is not completed by the production end time of the product type to be replaced, the production in the production lines L1 to L3 stops.

[0041] In FIG. 7, the third processing unit 22c creates a setup plan for performing an outer setup operation by preparing two sets of carts 5 consisting of eight replacement carts 5 based on the result of the simulation. For example, the third processing unit 22c assigns the cart group 1 to the replacement cart 5 for the product type X7 produced on the production line L3, and plans an outer setup operation of attaching the feeder 12 and the reel 14 corresponding to the product type X7 to the cart 5 of the cart group 1 during production preparation. Then, the third processing unit 22c creates a setup plan for collectively replacing the eight carts 5 attached to the component mounting devices M2 to M5 on the production line L3 after the production of the product type X6 with the eight carts 5 of the cart group 1.

[0042] Also, the third processing unit 22c creates a setup plan for assigning the eight removed carts 5 as replacement carts 5 for the cart group 1 and allocating them to the replacement carts 5 for the product type X9 produced on the production line L3. Then, the third processing unit 22c plans an outer setup operation of removing the unnecessary feeder 12 and reel 14 from the cart 5 of the cart group 1 and attaching the feeder 12 and reel 14 corresponding to the product type X9 to the cart 5 of the cart group 1 during production preparation.

[0043] Furthermore, since the outer setup operation for the replacement cart 5 for the product type X9 has not been completed by the end of the production of the product type X7, the third processing unit 22c plans to stop the production of the production line L3 until the outer setup operation for the cart 5 of the cart group 1 is completed. Then, after the completion of the outer setup operation for the cart 5 of the cart group 1, the third processing unit 22c creates a setup plan for collectively replacing the eight carts 5 attached to the component mounting devices M2 to M5 on the production line L3 with the eight replacement carts 5 prepared for the product type X9. Also, the third processing unit 22c plans to store the eight removed carts 5 as replacement carts 5 for the cart group 1 without performing the removal and attachment operations because the next product type cannot be assigned.

[0044] In this way, the third production plan can improve productivity by shortening the time during which the component mounting operations on the production lines L1 to L3 are stopped due to the changeover operation of product types, by performing production preparation for the replacement trolley 5 by external setup during the production of other groups. On the other hand, in the third production plan, since the replacement trolley 5 is used, the number of elements such as the feeder 12 and the trolley 5 used is larger than that in the first production plan and the second production plan.

[0045] In this way, the production plan creation unit 22 creates a plurality of production plans (first production plan, second production plan, third production plan) with different numbers of setup replacements for the elements to be mounted on the production equipment, based on the substrate information 26, the equipment information 27, and the element information 28. Further, the production plan creation unit 22 simulates the production of mounting substrates of a plurality of product types by the production equipment, and creates at least one production plan (third production plan) among the plurality of production plans based on the result of the simulation.

[0046] In addition, the production plan creation unit 22 creates a production plan for producing mounting substrates of a plurality of product types in the production lines L1 to L3 equipped with a plurality of production equipment (component mounting equipment M2 to M5). Further, the production plan creation unit 22 creates production plans (first production plan, second production plan, third production plan) for producing mounting substrates of a plurality of product types in the plurality of production lines L1 to L3 arranged on the floor F (see FIGS. 5 to 7).

[0047] Note that the production plans created by the production plan creation unit 22 are not limited to the above three. For example, the production plan creation unit 22 may perform a simulation without grouping a plurality of product types as in the first production plan, and create a production plan including a setup plan. Further, the production plan creation unit 22 may perform a simulation and create a production plan including a setup plan that combines external setup and internal setup.

[0048] In FIG. 3, the usage quantity calculation unit 23 calculates the usage quantity of elements for each production plan based on a plurality of production plans (the first production plan, the second production plan, and the third production plan). At this time, the usage quantity calculation unit 23 calculates the usage quantity for each type of element. The usage quantity calculation unit 23 associates the calculated usage quantity of the elements with the production plan and stores it in the storage unit 25 as element usage quantity information 30.

[0049] Here, with reference to FIGS. 5 to 7, the method of calculating the usage quantity of elements based on the production plan by the usage quantity calculation unit 23 will be described using the trolley 5 and the feeder 12 as examples. First, the method of calculating the usage quantity of the trolley 5 will be described. In the first production plan and the second production plan, no external setup using the replacement trolley 5 is planned. Therefore, the usage quantity calculation unit 23 calculates the usage quantity of the trolley 5 on the floor F as 24, which is the number of trolleys 5 mounted on the four component mounting devices M2 to M5 provided in the three production lines L1 to L3. Also, in the third production plan, the usage quantity calculation unit 23 calculates the usage quantity of the trolley 5 on the floor F by adding 16 trolleys in the two replacement trolley groups to the 32 trolleys 5 mounted on the four component mounting devices M2 to M5 provided in the three production lines L1 to L3, resulting in 40.

[0050] Next, the method of calculating the usage quantity of the feeder 12 will be described. In the first production plan, the usage quantity calculation unit 23 calculates the usage quantity of the feeder 12 required when performing an internal setup operation every time the product type produced in the three production lines L1 to L3 is changed. For example, the usage quantity calculation unit 23 calculates the required number of feeders 12 assuming that, for each type of feeder 12, the maximum number of feeders 12 mounted on the component mounting devices M2 to M5 during production and the same number of spare feeders 12 as the maximum number of mounted feeders 12 are prepared.

[0051] The usage quantity calculation unit 23 calculates the number of feeders 12 required when performing in-process setup operations for each change in the varieties belonging to or not belonging to a group in the second production plan. In the third production plan, the usage quantity calculation unit 23 prepares a replacement trolley 5 and calculates the number of feeders 12 required when replacing the trolleys 5 of the component mounting apparatuses M2 to M5 by batch replacement for each change in the varieties belonging to or not belonging to a group. For example, the usage quantity calculation unit 23 calculates the required number of feeders 12 assuming that, for each type of feeder 12, the maximum number of feeders 12 mounted on the trolleys 5 mounted on the in-production component mounting apparatuses M2 to M5 and the replacement trolley 5, and the same number of spare feeders 12 as the maximum number of mounted feeders 12 are prepared.

[0052] In FIG. 3, the display processing unit 24 causes the display unit 32 to display an element usage quantity display screen that displays the usage quantity of elements calculated for each production plan based on the element usage quantity information 30 stored in the storage unit 25.

[0053] Here, with reference to FIG. 8, an example of an element usage quantity display screen 50 that displays the usage quantity of elements on the floor F of the first production plan (FIG. 5), the second production plan (FIG. 6), and the third production plan (FIG. 7) displayed by the display processing unit 24 on the display unit 32 for each type of element will be described. On the element usage quantity display screen 50, a used trolley number display frame 51 and a used feeder number display frame 52 are displayed. In the used trolley number display frame 51, the number of used trolleys for each type of trolley 5 is displayed for each of the first production plan, the second production plan, and the third production plan. In this example, as the types of trolleys 5, the "30-unit trolley" on which 30 standard-size feeders 12 can be mounted, the "20-unit trolley" on which 20 can be mounted, and the "17-unit trolley" on which 17 can be mounted, the number of used trolleys is displayed for each.

[0054] In the feeder number display frame 52, the number of feeders used for each type of feeder 12 is displayed for each of the first production plan, the second production plan, and the third production plan. As the types of the feeder 12, for example, they are classified by the width of the carrier tape to be conveyed (such as 8 mm, 12 mm), the number of carrier tapes that can be conveyed in parallel (single, double), the type of component storage body to be conveyed (carrier tape, stick), and the like. In this example, the number of feeders used in the first production plan that does not consider the optimization of productivity and the number of setup changes is the smallest. Also, the number of feeders used in the third production plan that performs external setup considering productivity and uses the replacement cart 5 is the largest.

[0055] In the above example, the usage number calculation unit 23 calculates the number of elements (cart 5, feeder 12) used on the floor F where a plurality of production lines L1 to L3 are arranged, and the display unit 32 displays the number of elements used on the floor F for each production plan (FIG. 8), but it is not limited to this example. For example, the usage number calculation unit 23 may calculate the number of elements used for each of the production lines L1 to L3, and the display unit 32 may display the number of elements used for each of the production lines L1 to L3 for each production plan. Also, the usage number calculation unit 23 may calculate the number of elements used for each production apparatus (component mounting apparatuses M2 to M5), and the display unit 32 may display the number of elements used for each production apparatus.

[0056] Next, a production support method for supporting the production of mounting substrates of a plurality of varieties by a production apparatus will be described along the flow of FIG. 9. First, the acquisition unit 21 acquires substrate information 26 regarding a plurality of varieties of mounting substrates, apparatus information 27 regarding the production apparatus, and element information 28 regarding elements detachable from the production apparatus (ST1: acquisition step). Next, the production plan creation unit 22 creates a plurality of production plans for producing a plurality of varieties of mounting substrates based on the substrate information 26, the apparatus information 27, and the element information 28 (ST2: production plan creation step). Here, first, the first processing unit 22a creates the first production plan (FIG. 5), the second processing unit 22b creates the second production plan (FIG. 6), and the third processing unit 22c creates the third production plan (FIG. 7).

[0057] Next, the usage calculation unit 23 calculates the usage of elements for each production plan based on the created multiple production plans (ST3: element usage calculation step). Here, the usage calculation unit 23 calculates the usage of elements for each production plan based on the created first production plan, second production plan, and third production plan. Next, the display processing unit 24 causes the display unit 32 to display an element usage display screen 50 (FIG. 8) that displays the usage of elements calculated for each production plan (ST4: display step).

[0058] In this way, the production plan creation unit 22 creates multiple production plans (first production plan, second production plan, third production plan) for producing mounting substrates of multiple product types based on the substrate information 26, device information 27, and element information 28 (ST2). The usage calculation unit 23 calculates the usage of elements for each production plan based on the created multiple production plans (ST3). Then, the display unit 32 displays the usage of elements calculated for each production plan (ST4). As a result, managers and the like can appropriately consider additional purchases of elements and the disposal of unnecessary inventory by referring to the required quantities of different elements for each production plan.

[0059] As described above, the management computer 3 of the present embodiment includes a production plan creation unit 22 that creates multiple production plans (first production plan, second production plan, third production plan) for producing mounting substrates of multiple product types based on the substrate information 26 regarding multiple product types of mounting substrates, the device information 27 regarding production devices (component mounting devices M2 to M5), and the element information 28 regarding elements (carts 5, feeders 12) that can be attached to and detached from the production devices. A usage calculation unit 23 that calculates the usage of elements for each production plan based on the created multiple production plans, and a display unit 32 that displays the usage of elements calculated for each production plan. It is a production support device that supports the production of mounting substrates of multiple product types by the production devices.

[0060] As a result, managers and the like can appropriately consider the elements that are attached to and detached from the production devices and used.

[0061] In the above description, the number of detachable elements used in the production apparatuses included in the production lines L1 to L3 is calculated based on the apparatus information 27 and the element information 28. However, the upper limit number of elements that can be used, which is the maximum number of elements that can be used as the number of elements used, may be used. Then, the number-of-uses calculation unit 23 may use the upper limit number of uses and repeatedly perform the calculation based on the created production plan until the number of elements used becomes equal to or less than the upper limit number of uses. Further, when the number of elements used does not become equal to or less than the upper limit number of uses even after repeatedly performing the calculation a predetermined number of times, the number-of-uses calculation unit 23 may notify the user to that effect.

[0062] Also, the upper limit number of uses may be used in all of the plurality of production plans (first production plan, second production plan, third production plan) in the above description, or may be used at least in one case, for example, when calculating the number of elements used in the third production plan. Further, the upper limit number of uses may be the number of elements held by the user or a number arbitrarily specified by the user. By using the upper limit number of uses in this way, the number of elements used can be appropriately calculated according to the user's specification. Therefore, the user can more accurately grasp the appropriate number of elements used.
