[0002] In a production line composed of production equipment such as component mounting equipment, products such as electronic circuit boards with components mounted on a board are continuously produced. In order to estimate the production capacity of such a production line, in addition to the processing capacity of each production equipment, it is necessary to take into account temporary suspension of the production equipment due to operator work such as replenishing parts and other materials to the production equipment and responding to errors in the production equipment (for example, Patent Document 1). It is disclosed that the system described in Patent Document 1 estimates the production capacity of a component mounting line based on pre-stored information such as the configuration of the production line for which production capacity is to be estimated, information on the production equipment, and the frequency of operator work, as well as input information on the operator and a production plan.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] An embodiment of the present invention will be described in detail below with reference to the drawings. The configuration, screen display, etc. described below are examples for explanation and can be appropriately changed according to the specifications of the production system, production line, production equipment, production management equipment, and production capacity management equipment. In the following, the same reference numerals are used for corresponding elements in all drawings, and duplicated explanations will be omitted. In Figs. 1 and 2, the left side of the paper is upstream and the right side is downstream in the board transport direction (left-right direction in Figs. 1 and 2). Also, in Figs. 1 and 2, the lower side of the paper is the front and the upper side is the rear in the direction perpendicular to the board transport direction in the horizontal plane (up-down direction in Figs. 1 and 2).

[0012] First, the configuration of the production system 1 will be described with reference to FIG. 1. The production system 1 is configured to include floors F1-F3 in a customer's factory, and a support center S that is established in a location away from the floors F1-F3 (factory) and supports the customer's production activities. Each of the floors F1-F3 is equipped with a production line that produces electronic circuit boards with components mounted on the board as a product. The floors F1-F3 may be installed in the same factory, or may be installed in multiple factories. Each of the floors F1-F3 has the same configuration, and below, floor F1 will be described.

[0013] In FIG. 1, three production lines L1 to L3 are installed on floor F1. The production devices of the production lines L1 to L3 are connected to an in-house communication network 2 such as a LAN (Local Area Network), and are connected to a production management device 3 via an internal communication unit 4. The production management device 3 has a function of creating data and parameters required for the operation of the production devices of the production lines L1 to L3, and transmitting the data to each production device. Each production device transmits data such as the operation status and work history of each production device to the production management device 3. In addition to the production management device 3, floor F1 may be configured to include a line management device for managing the production of electronic circuit boards for each production line L1 to L3.

[0014] Each of the production lines L1 to L3 has component mounting lanes L1F to L3F and component mounting lanes L1R to L3R at the front and rear, respectively, which have the function of producing electronic circuit boards. The number of production lines L1 on the floor F1 does not need to be three, and may be one, two, or four or more. The number of component mounting lanes on the production lines L1 to L3 does not need to be two at the front and rear, and may be one. In the example shown in FIG. 1, the production management device 3 is installed inside the floor F1 on which the production lines L1 to L3 are installed, but the production management device 3 may be installed outside the floor F1. The production management device 3 may be provided on each of the floors F1 to F3 in the factory, or a single production management device 3 installed in the factory may manage the production lines L1 to L3 on each of the floors F1 to F3.

[0015] In Fig. 1, a production capacity management device 7 is installed in a support center S. The production management devices 3 on multiple floors F1 to F3 each include an external communication unit 5. In addition, the production capacity management device 7 in the support center S includes an external communication unit 8. The external communication units 5 and 8 are connected to an off-premise communication network 6 such as the Internet or a mobile communication line. With this configuration, the production management device 3 and the production capacity management device 7 can exchange information via the off-premise communication network 6.

[0016] The production capacity management device 7 acquires information on production devices and performance information from the production management device 3 on each floor F1 to F3 and stores the information in a database. In addition, the production capacity management device 7 has a function of generating virtual capacity information for the production lines L1 to L3 from the information stored in the database in response to a request from the production management device 3, and estimating the virtual production capacity.

[0017] Next, the detailed configuration of the production lines L1 to L3 will be described with reference to Fig. 2. The production lines L1 to L3 have the same configuration, and the production line L1 will be described below. The production line L1 is configured by connecting in series from upstream to downstream in the board transport direction a board supply device M1, a board allocation device M2, a solder printing device M3, a print inspection device M4, a board allocation device M5, component mounting devices M6 to M9, a board allocation device M10, a mounting inspection device M11, a reflow device M12, a board allocation device M13, and a board recovery device M14.

[0018] The board allocation device M2, solder printing device M3, print inspection device M4, board allocation device M5, component mounting devices M6 to M9, board allocation device M10, mounting inspection device M11, reflow device M12, and board allocation device M13 are connected to the production management device 3 via the on-site communication network 2 and the internal communication unit 4. The board supply device M1 has two conveyors 9a and 9b at the front and rear, and the conveyors 9a and 9b have the function of delivering the supplied boards 10A and 10B of different board types to the downstream board allocation device M2. The boards 10A and 10B may be the same board type.

[0019] In Fig. 2, the board allocation devices M2, M5, M10, and M13 are production devices that have a transport conveyor as a board allocation work section and a conveyor movement mechanism that moves the transport conveyor between the front and rear, and perform board allocation work of allocating and transferring boards 10A and 10B received from upstream production equipment to downstream production equipment. The board allocation devices M2 and M10 receive boards 10A and 10B from two conveyors, the front and rear, connected upstream onto the transport conveyor, move the transport conveyor while holding the boards 10A and 10B, and transfer them in order to one conveyor connected downstream. Information regarding the order of boards 10A and 10B transferred downstream is transmitted from the built-in device communication unit to the production management device 3 via the on-site communication network 2 and the internal communication unit 4.

[0020] The board allocation devices M5 and M13 receive the boards 10A and 10B from a single conveyor connected upstream onto a transport conveyor, move the transport conveyor while holding the boards 10A and 10B, and deliver them to the two front and rear conveyors connected downstream. When delivering them downstream, the boards 10A and 10B, which are mixed and delivered from the upstream, are allocated to a predetermined front or rear conveyor based on information about the order of the boards 10A and 10B received by the built-in management communication unit and transmitted from the production management device 3 via the on-site communication network 2 and the internal communication unit 4. Note that, when the component mounting devices M6 to M9 are single lane types having one conveyor, the production line L1 does not need to be equipped with the board allocation devices M2, M5, M10, and M13.

[0021] In FIG. 2, the solder printer M3 is a production device that executes a solder printing operation in which a solder printing work unit prints solder on the substrates 10A and 10B to be mounted. When the solder stored in the solder printer M3 is consumed during the repeated solder printing operation (when solder runs out), an operator executes a solder replenishing operation. In addition, in a changeover operation to switch the electronic circuit substrates to be produced, an operator in the solder printer M3 executes operations such as replacing the mask for solder printing and changing the arrangement of the support pins that support the substrates 10A and 10B from below during solder printing. The print inspection device M4 is a production device that executes a print inspection operation in which a print inspection work unit including a solder inspection camera executes a print inspection operation to inspect the state of the solder printed on the substrates 10A and 10B.

[0022] 2, component mounting devices M6-M9 are production devices that perform component mounting work by mounting components D onto boards 10A and 10B using a component mounting work unit that includes two front and rear conveyors, two component supply units, and two mounting heads. Note that production line L1 is not limited to a configuration of four component mounting devices M6-M9, and may include one component mounting device M6-M9 or five or more component mounting devices. In component mounting devices M6-M9, two conveyors extending in the board transport direction are arranged in parallel at the front and rear, and two component supply units are arranged on the outer sides (front and rear) of the two juxtaposed conveyors.

[0023] The component supply unit includes a plurality of tape feeders that feed the components D by tape-feeding the carrier tape holding the components D, and a tray feeder that supplies the components D while switching between trays holding the plurality of components D, and supplies the components D to a pick-up position by the mounting head. The mounting head includes a suction nozzle that vacuum-sucks the components D, and performs a component mounting operation by picking up the components D supplied by the component supply unit and transferring and mounting them on the boards 10A, 10B that are transported, positioned and held by the conveyor. The tape feeders and trays of the component supply unit are set with carrier tapes and trays that hold the specified components D during the changeover so that the specified components D are supplied according to the type of electronic circuit board to be produced (in other words, the components D are arranged).

[0024] The component mounting devices M6 to M9 perform component mounting work in various mounting modes based on production data. In the alternating mounting mode, component mounting work is performed in which two mounting heads alternately transfer and mount components onto the boards 10A and 10B. In the independent mounting mode, component mounting work is performed in which two mounting heads independently transfer and mount components onto the boards 10A and 10B held by two conveyors, respectively. The multiple connected component mounting devices M6 to M9 can perform component mounting work in the same mounting mode, or can perform component mounting work in separate mounting modes.

[0025] In the double lane production method, two conveyors each carry boards 10A and 10B, and a mounting head transfers and mounts the components. In the single lane production method, only one of the two conveyors carries boards 10A and 10B, and a mounting head transfers and mounts the components.

[0026] In the component mounting devices M6 to M9, when the components D held by the component supply unit are consumed during the repeated component mounting operation and fall below a predetermined remaining number (when a component out-of-parts warning occurs), or when the components D run out (when a component out-of-parts occurs), an operator performs a task of replenishing the components D (replenishing the carrier tape, replacing the tray, etc.). In addition, when an apparatus error occurs that stops the component mounting devices M6 to M9, such as a suction error where the suction nozzle does not properly suction the components D, or an error where the tape feeder stops supplying the components D due to the carrier tape getting tangled (jamming), an operator performs a task of recovering from the apparatus error.

[0027] In addition, in a changeover operation to switch the electronic circuit boards to be produced, in component mounting devices M6 to M9, operators replace tape feeders, trays, mounting heads, suction nozzles, change the arrangement of support pins that support boards 10A and 10B from below during component mounting, etc. In addition, replacement operations are performed for equipment options such as a nozzle changer that holds multiple suction nozzles and automatically replaces them with suction nozzles attached to the mounting head during component mounting operation, a transfer unit that is used to transfer paste to the electrodes of component D before mounting component D held by the suction nozzle on boards 10A and 10B, and an electrical characteristic measuring device that measures the electrical characteristics of component D held by the suction nozzle.

[0028] In Fig. 2, when performing the above-mentioned tasks, the operator moves to the operation surface (front or rear) of the component mounting device M6-M9 to be operated and performs the task. There are also device errors in which only the component mounting task at the front or rear where the device error occurs stops, while the component mounting task at the opposite side continues without stopping, and device errors that are automatically recovered by the recovery process of the component mounting devices M6-M9. Thus, the component mounting devices M6-M9 are production devices that have equipment elements such as tape feeders, tray feeders, mounting heads, nozzle changers, transfer units, and electrical characteristic measuring devices, and perform component mounting tasks to produce electronic circuit boards (products).

[0029] 2, the mounting inspection device M11 is a production device that performs a mounting inspection operation to inspect the state of the components D mounted on the boards 10A, 10B by a mounting inspection operation section including a component inspection camera. The reflow device M12 is a production device that performs a board heating operation to heat the boards 10A, 10B carried into the device by a board heating section, harden the solder on the boards 10A, 10B, and join the electrodes of the boards 10A, 10B to the components D. The board recovery device M14 has two conveyors 9c, 9d, front and rear, and the conveyors 9c, 9d have the function of receiving and recovering the boards 10A and 10B, respectively, from the upstream board sorting device M13.

[0030] In this way, in production line L1, components D are mounted on board 10A supplied to the front conveyor 9a of board supplying device M1, and the board 10A with components D mounted thereon is collected by the front conveyor 9c of board collecting device M14. This path becomes the front component mounting lane L1F. Similarly, in production line L1, components D are mounted on board 10B supplied to the rear conveyor 9b of board supplying device M1, and the board 10B with components D mounted thereon is collected by the rear conveyor 9d of board collecting device M14. This path becomes the rear component mounting lane L1R.

[0031] In the double lane production method, component mounting work is performed in both the front component mounting lane L1F and the rear component mounting lane L1R. In the single lane production method, component mounting work is performed in only one of the front component mounting lane L1F and the rear component mounting lane L1R. Hereinafter, board 10A on which component D is mounted and board 10B on which component D is mounted will be referred to simply as "electronic circuit board B."

[0032] Next, the configuration of the production system 1 (production capacity estimation system) equipped with the production management device 3 and the production capacity management device 7 will be described with reference to Fig. 3. In this section, among the multiple functions equipped in the production system 1, the configuration related to the function of generating virtual capacity information of the production lines L1 to L3 based on the operation records of the production devices and estimating the virtual production capacity will be mainly described.

[0033] The production system 1 of this embodiment simply estimates the production capacity of electronic circuit boards B (products) produced by production lines with different configurations. Therefore, the production system 1 does not require the input of detailed information on the production equipment and electronic circuit boards B used to estimate the production capacity, but generates information required to estimate the production capacity based on the operation records of the production lines L1 to L3. In addition, configuration information of the electronic circuit boards B used to estimate the production capacity is also generated based on the operation records. Furthermore, the production system 1 estimates the production capacity of the production lines with different configurations mainly based on the production capacity of the component mounting devices M6 to M9, which have a large influence on the production capacity of the production lines L1 to L3.

[0034] First, the configuration of the production management device 3 will be described. The production management devices 3 installed on floors F1 to F3 have the same configuration, and floor F1 will be described as an example here. An internal communication unit 4, an external communication unit 5, an input unit 11, and a display unit 12 are connected to the production management device 3 installed on floor F1. The production management device 3 includes a production management storage unit 13, a performance collection unit 16, a display processing unit 17, and a control unit (not shown). The production management storage unit 13 is a storage device such as a semiconductor memory or a hard disk drive, and stores operation performance 14, display information 15, etc.

[0035] 3, the input unit 11 is an input device such as a keyboard, a touch panel, a mouse, etc., and is used when inputting operation commands and data. The display unit 12 is a display device such as a liquid crystal panel, and in addition to displaying various data stored in the production management storage unit 13, it also displays various information such as an operation screen and an input screen for operation by the input unit 11. The control unit is, for example, a CPU (Central Processing Unit), and controls the entire production management device 3.

[0036] 3, the performance record collecting unit 16 periodically collects performance records of component mounting work from component mounting devices M6 to M9 (production devices) on production lines L1 to L3 installed on floor F1. The performance records of component mounting work include information such as the production start date and time, the production end date and time (the time when the production device produced the product), the number of pieces produced, the number of work errors, the error rate (frequency), the number of operational errors and their contents, and information on the operators who performed the work on floor F1 (work hours, working hours, number of people, responsibilities, etc.).

[0037] The result collecting unit 16 also collects device information such as the configuration of the equipment elements of the component mounting devices M6-M9, production data for operating the component mounting devices M6-M9 (production devices) to produce the electronic circuit board B (product), the type of electronic circuit board B and its production order, information on the configuration of the electronic circuit board B (board size, number of mounted components, etc.), changeover time, etc. The result collecting unit 16 stores the collected device information, operation results, production data, etc. of the component mounting devices M6-M9 (plurality of production devices) as operation results 14 in the production management storage unit 13 in association with information identifying the production lines L1-L3 on which the component mounting work was performed and the component mounting devices M6-M9.

[0038] 3, a production capacity management device 7 installed in a support center S has a function of generating virtual capacity information of production lines L1 to L3 based on information acquired from production management devices 3 installed on floors F1 to F3 of a customer's factory, a function of estimating virtual production capacity based on the virtual capacity information, etc. An external communication unit 8 and a storage device 20 are connected to the production capacity management device 7.

[0039] The storage device 20 is a semiconductor memory or a hard disk drive, and includes a database 21 that stores information acquired from production management devices 3 installed on multiple floors F1 to F3. The storage device 20 also stores virtual capacity information 22, standard capacity information 23, virtual production capacity 24, etc. The production capacity management device 7 includes information processing devices such as an acquisition unit 30, a virtual capacity generation unit 31, a virtual capacity setting unit 32, an estimation unit 33, a display information generation unit 34, and a control unit (not shown).

[0040] Each information processing device may be configured with independent hardware assets, or may be configured with a common CPU and a program for each information processing. The control unit is, for example, a CPU (Central Processing Unit) and controls the entire production capacity management device 7. Furthermore, the production capacity management device 7 does not need to be configured with one computer, and may be configured with multiple devices. For example, the storage device 20 and all or some of the information processing devices that make up the production capacity management device 7 may be provided in a cloud via a server.

[0041] 3, the acquisition unit 30 acquires device information, operation records, production data, operator information, and the like of multiple component mounting devices M6-M9 (production devices) on the production lines L1-L3 installed on each floor F1-F3 from the production management devices 3 on the multiple floors F1-F3 via the external communication unit 8. Specifically, the acquisition unit 30 acquires necessary information from the operation records 14 collected by the record collection units 16 of the production management devices 3 installed on the floors F1-F3. The acquisition unit 30 stores the acquired information in a database 21. In the database 21 shown in FIG. 4, the information acquired from the production management devices 3 on the multiple floors F1-F3 is stored as information on the operation period (by month) for each floor F1-F3.

[0042] 3 and 4, the virtual capacity generation unit 31 generates virtual capacity information 22 of the production lines L1 to L3 from the equipment information and operation records stored in the database 21, and stores the information in the storage device 20. In the example of FIG. 4, the virtual capacity generation unit 31 generates the virtual capacity information 22 in units corresponding to the operation periods (by month) of the floors F1 to F3 stored in the database 21. Specifically, the virtual capacity generation unit 31 generates information on the equipment elements (tape feeders, tray feeders, mounting heads, etc.) of the component mounting devices M6 to M9 (production devices) and information on the specifications (model, number of conveyors, number of mounting heads, etc.) of the component mounting devices M6 to M9 from the equipment information stored in the database 21.

[0043] Further, the virtual capacity generation unit 31 generates information (line tact information) on the time (line tact time, etc.) required for the production lines L1 to L3 to produce the electronic circuit board B (product), and information (event information) on events (replenishment work for components D, recovery work from equipment errors, etc.) that require operator work on the production lines L1 to L3 and their occurrence frequency. Further, the virtual capacity generation unit 31 generates information on the product, such as the type, configuration (size of boards 10A and 10B, number of mounted components, etc.) of the produced electronic circuit board B (product), from the operation records stored in the database 21. In this way, the storage device 20 is a storage unit that stores the virtual capacity information 22 generated by the virtual capacity generation unit 31 for each operation record.

[0044] Moreover, the production capacity management device 7 of this embodiment includes an acquisition unit 30 that acquires device information and operation records of multiple component mounting devices M6-M9 (production devices) equipped on the production lines L1-L3 on which electronic circuit boards B (products) are produced, a virtual capacity generation unit 31 that generates virtual capacity information 22 of the production lines L1-L3 from the device information and operation records, and a storage device 20 (storage unit) that stores the generated virtual capacity information 22 for each operation record. This makes it possible to easily generate the virtual capacity information 22 used to estimate the production capacities of the production lines L1-L3 having different configurations.

[0045] 3 and 4, standard capability information 23 stores standard equipment information including catalog values ​​of specifications (model, number of conveyors, number of mounting heads, CPH, etc.) of component mounting devices M6-M9 that can be connected to production lines L1-L3 and used. Standard capability information 23 also stores standard equipment element information including catalog values ​​of specifications of equipment elements (tape feeders, tray feeders, mounting heads, etc.) that can be used by component mounting devices M6-M9.

[0046] The virtual capacity setting unit 32 sets virtual capacity information 22 for the virtual production lines A1, A2 that differ from the proven production lines L1-L3 in terms of component mounting devices M6-M9 and facility elements, etc., based on commands transmitted from the production management devices 3 on the floors F1-F3 and the virtual capacity information 22 and standard capacity information 23 for the production lines L1-L3. The virtual capacity setting unit 32 stores the set virtual capacity information 22 for the virtual production lines A1, A2 in the storage device 20.

[0047] 3, the estimation unit 33 estimates the virtual production capacities 24 of the production lines L1 to L3 based on the virtual capacity information 22 of the production lines L1 to L3. The estimation unit 33 also estimates the virtual production capacities 24 of the virtual production lines A1 and A2 based on the virtual capacity information 22 of the virtual production lines A1 and A2. The estimation unit 33 stores the estimated virtual production capacities 24 in the storage device 20. The display information generation unit 34 generates display information 15 for displaying results of processing executed in accordance with commands transmitted from the production management devices 3 on the floors F1 to F3 (e.g., information on the virtual production lines A1 and A2, the estimated virtual production capacities 24) on the display unit 12 of the production management device 3, and transmits the display information 15 to the production management device 3 that is the source of the commands.

[0048] The display information 15 transmitted from the production capacity management device 7 is stored in the production management storage unit 13 of the production management device 3 that is the transmission source of the command. The display processing unit 17 provided in the production management device 3 displays the received display information 15 on the display unit 12. For example, the display unit 12 displays the virtual production capacity 24 transmitted from the production capacity management device 7. The display processing unit 17 also displays various screens for creating commands to be transmitted to the production capacity management device 7 on the display unit 12, and supports the input of information and commands by the input unit 11.

[0049] 5 to 10, various screens for executing a simulation of the production capacity of the production lines L1 to L3 that the display processing unit 17 displays on the display unit 12, and examples of information input by the input unit 11 will be described. The production capacity simulations described below are used by managers and owners of factories and floors F1 to F3 when adding new production equipment to increase the production capacity of the existing production lines L1 to L3, or when easily estimating the effects of establishing new production lines.

[0050] First, an example of a floor setting screen 40 displayed on the display unit 12 by the display processing unit 17 will be described with reference to Fig. 5. The floor setting screen 40 is used when specifying existing production lines L1 to F3 for which virtual capacity information is to be generated. In this example, the existing production lines L1 to L3 are specified for each of the existing floors F1 to F3. The floor setting screen 40 is provided with a menu selection area 41, a floor specification area 42, and a floor information display area 43.

[0051] In the menu selection area 41, a floor setting button 41a, a line setting button 41b, and a SIM setting button 41c are arranged in the order of the tasks for estimating production capacity. When the manager operates the input unit 11 to press the floor setting button 41a, the display processing unit 17 switches the display unit 12 to a floor setting screen 40. Similarly, when the line setting button 41b is pressed, the display processing unit 17 switches the display unit 12 to a line setting (main) screen 44 (FIG. 6). Moreover, when the SIM setting button 41c is pressed, the display processing unit 17 switches the display unit 12 to a simulation setting (floor setting) screen 59 (FIG. 9).

[0052] 5, an add floor button 42a and a floor information setting frame 42b are arranged in the floor designation area 42. When the add floor button 42a is pressed, the display processing unit 17 switches the display unit 12 to a floor addition screen (not shown). When floors F1 to F3 to be added are designated on the add floor screen, the display processing unit 17 transmits a command to the production capacity management device 7 of the support center S to "generate virtual capacity of the designated floor."

[0053] In the production capacity management device 7 that received the command, the acquisition unit 30 acquires, from the production management device 3 installed on the specified floor, the device information and operation record 14 of the component mounting devices (production devices) equipped in the production line set up on the floor. Next, the virtual capacity generation unit 31 generates virtual capacity information 22 of the production line from the acquired device information and operation record 14. Next, the display information generation unit 34 generates display information 15 from the generated virtual capacity information 22 to be displayed on the display unit 12 by the production management device 3 that sent the command, and transmits it to the production management device 3 that sent it. The transmitted display information 15 is stored in the production management storage unit 13.

[0054] 5, the floor information setting frame 42b displays information transmitted from the production capacity management device 7, such as the floor names and number of lines of the floors F1 to F3 to which the virtual capacity information 22 has been added. In this example, virtual capacity information 22 has been added for floor F1 with three lines, floor F2 with seven lines, and floor F3 with two lines. When the delete button corresponding to the floor name is pressed, the virtual capacity information 22 of that floor is deleted from the floor settings. When the edit button is pressed, the display processing unit 17 switches the display unit 12 to a line setting (main) screen 44 for changing the configuration of that floor.

[0055] In the floor information display area 43, a floor information display frame 43a is arranged to display information transmitted from the production capacity management device 7. The floor information display frame 43a is provided with a floor selection tab 43b, a line configuration display field 43c, and line selection buttons 43d and 43e. When any of the floor selection tabs 43b is selected, the floors F1 to F3 displayed in the line configuration display field 43c are changed to the production lines of the selected floor. When the line selection buttons 43d and 43e are pressed, the production lines L1 to L3 displayed in the line configuration display field 43c are changed in order.

[0056] In this example, in FIG. 5, the line configuration display field 43c displays the component mounting devices M6 to M9 equipped on the production line L1 of the floor F1 shown in FIG. 2 in the order in which they are connected. The component mounting devices M6 and M7 are component mounting devices of the model "D1", and the component mounting devices M8 and M9 are component mounting devices of the model "D2". The component mounting device of the model "D1" is equipped with two conveyors and two mounting heads at the front and rear along the board transport direction, respectively, and has "2" stages and "4" tables. The component mounting device of the model "D1" is equipped with two conveyors and one mounting head at the front and rear, respectively, and has "1" stage and "2" tables.

[0057] For component mounting devices M6 to M9 displayed in the line configuration display field 43c, a table configuration display 43f showing the configuration of the front and rear feeder tables and a mounting head configuration display 43g showing the configuration of the mounting heads mounted on the front and rear are displayed. "c17" in the table configuration display 43f indicates that a dolly capable of mounting 17 tape feeders, "c30" indicates that a dolly capable of mounting 30 tape feeders, "f13" indicates that a dolly capable of mounting 13 tape feeders, and "t20" indicates that a tray feeder capable of mounting 20 trays is arranged. "H16" in the mounting head configuration display 43g indicates that a mounting head equipped with 16 suction nozzles is installed, "H8" indicates that a mounting head equipped with 8 suction nozzles is installed, and "H3" indicates that a mounting head equipped with 3 suction nozzles is installed.

[0058] In this way, the virtual capacity information 22 includes the names of component mounting devices (production devices) that make up the production line (virtual production line) set up from multiple operation records 14, the equipment elements required to produce the electronic circuit board B (product) possessed by the component mounting devices, and information on the component mounting devices.

[0059] In Fig. 5, when the line setting button 41b is pressed, the display processing unit 17 causes the display unit 12 to display a line setting (main) screen 44. Next, with reference to Fig. 6, an example of the line setting (main) screen 44 will be described. The line setting (main) screen 44 is used when setting the configuration of a production line for estimating production capacity. In Fig. 6, information on existing production lines L1 to L3 on floor F1 is displayed. The line setting (main) screen 44 is provided with a menu selection area 41, a line designation area 45, and a line information display area 46.

[0060] 6, a line designation area 45 has an add line button 45a and a line information setting frame 45b arranged therein. When the add line button 45a is pressed, the display processing unit 17 switches the display unit 12 to a line setting (add equipment) screen 47 (FIG. 7). The line information setting frame 45b displays information such as the number of mounting devices, the number of stages, the lanes, the mounting mode, and the production method of the production lines L1 to L3 on the floor F1, which are included in the virtual capacity information 22. For example, the production line L1 has four dual-lane component mounting devices connected together, the number of stages is "6," the mounting mode is "alternate mounting mode," and the production method is "both lanes production."

[0061] When the delete button corresponding to the line name is pressed in the line information setting frame 45b, the virtual capacity information 22 of that production line is deleted. When the edit button is pressed, the display processing unit 17 switches the display unit 12 to a line setting (equipment addition) screen 47 (FIG. 7) for changing the configuration of that production line. A line information display frame 46a is arranged in the line information display area 46. The line information display frame 46a is provided with a line selection tab 46b and a line configuration display field 46c. When any one of the line selection tabs 46b is selected, the configuration of the component mounting devices M6 to M9 of the selected production lines L1 to L3 is displayed in the line configuration display field 46c.

[0062] In Fig. 6, when the line addition button 45a is pressed, the display processing unit 17 displays a line setting (equipment addition) screen 47 on the display unit 12. Next, an example of the line setting (equipment addition) screen 47 will be described with reference to Fig. 7. The line setting (equipment addition) screen 47 is used when adding a component mounting device (production equipment) to an existing production line or when adding a new production line. Fig. 7 shows an example of adding a new production line to floor F1.

[0063] When switching the display unit 12 to the line setting (equipment addition) screen 47, the display processing unit 17 transmits a command to the production capacity management device 7 of the support center S to "transmit standard capacity information." In the production capacity management device 7 that has received the command, the display information generation unit 34 generates display information 15 (standard list) for the transmission source production management device 3 to display on the display unit 12 based on the standard capacity information 23 stored in the storage device 20, and transmits the display information 15 to the transmission source production management device 3. The transmitted display information 15 is stored in the production management storage unit 13.

[0064] In FIG. 7, the line setting (equipment addition) screen 47 is provided with a menu selection area 41, a step switching area 48, and a line setting area 49. In the step switching area 48, a line name input field 48a, a step display frame 48b, a previous button 48c, and a next button 48d are arranged. In the line name input field 48a, the line name (new line LX) of the production line to be newly created is input. When production equipment (component mounting devices) are added to the existing production lines L1 to L3, the line name input field 48a displays the line names of the existing production lines L1 to L3 as initial values. In the step display frame 48b, the line setting work is displayed in the order of steps. When the previous button 48c or the next button 48d is operated, the display switches to the line setting screen of the previous step or the next step.

[0065] Arranged in the line setting area 49 are a line configuration setting frame 50, a line configuration information display frame 51, a production equipment selection frame 52, and a production equipment information display frame 53. The manager operates the input unit 11 to select one of the component mounting devices (production equipment) displayed in the production equipment selection frame 52, and repeats the task of moving it (drag-and-drop) to a predetermined position in the line configuration setting frame 50, thereby setting the configuration of the production line (new line LX) in the line configuration setting frame 50.

[0066] This operation allows the manager to easily set and change the configuration of a new production line (hereinafter referred to as a "virtual production line") for estimating production capacity. The line configuration information display frame 51 displays configuration information of the virtual production line set in the line configuration setting frame 50 (total number of stages, total number of mounting heads, total number of tape feeders, total number of CPH, etc.). When the configuration of the virtual production line is changed by adding or deleting component mounting devices in the line configuration setting frame 50, the configuration information of the virtual production line in the line configuration information display frame 51 is changed accordingly.

[0067] 7, the production equipment selection frame 52 is provided with list selection tabs 52a. When any of the list selection tabs 52a is selected, the list of component mounting devices (production equipment) displayed in the production equipment selection frame 52 is changed. When the "standard list" tab is selected, a standard list created from the standard capacity information 23 transmitted from the production capacity management device 7 is displayed. When the "Floor F1" tab is selected, a list of component mounting devices (production equipment) that have a history of use and are included in the virtual capacity information 22 of floor F1 is displayed. The same is true for the "Floor F2" tab and the "Floor F3" tab.

[0068] In the production equipment selection frame 52, the catalog value of the model and the chip per hour (CPH), which is the number of components that can be mounted per unit time, is displayed as information on the component mounting device (production equipment). CPH is information calculated from the number of mounted components on the electronic circuit board B and the production time (line tact), etc. In other words, CPH is information on the number of electronic circuit boards B that the component mounting device produces in a predetermined period of time. The order of the component mounting devices displayed can be changed by selecting the condition of "display / sort order" from the drip-down list 52b provided in the production equipment selection frame 52. When the forward buttons 52c and 52d provided in the production equipment selection frame 52 are pressed, the order of the component mounting devices displayed is changed. In the production equipment information display frame 53, detailed information on the component mounting device selected in the production equipment selection frame 52 (here, model D1) is displayed.

[0069] 7, when setting a new virtual production line, the line configuration setting frame 50 initially displays "blank". When making changes to existing production lines L1 to L3, such as by adding a component mounting device, the line configuration setting frame 50 initially displays the configuration of the existing production lines L1 to L3. When the Next button 48d is pressed, the display processing unit 17 causes the display unit 12 to display a line setting (equipment options) screen 54 (FIG. 8).

[0070] Next, an example of the line setting (equipment option) screen 54 will be described with reference to Fig. 8. The line setting (equipment option) screen 54 is used when setting or changing equipment elements (equipment options) of component mounting devices (production equipment) that constitute a virtual production line. Fig. 8 shows an example of setting equipment options for a new virtual production line (new line LX). For component mounting devices in the standard list, predetermined standard equipment elements are set as initial values. Furthermore, for component mounting devices included in the virtual capacity information 22, equipment elements at the time of production are set as initial values. The line setting (equipment option) screen 54 is provided with a menu selection area 41, a step switching area 48, a line configuration display area 55, and an equipment option setting area 56.

[0071] A line configuration display frame 57 is arranged in the line configuration display area 55. In the line configuration display frame 57, component mounting devices (production equipment) that make up the virtual production line are displayed in the order of connection. An equipment option setting frame 58 is arranged in the equipment option setting area 56. In the equipment option setting frame 58, drag buttons are arranged for selecting and setting equipment options (equipment elements) for each table (TBL) of component mounting devices that make up the virtual production line. Selectable equipment options include the type of mounting head (head), whether or not to use (type) a nozzle changer (changer), the type of cart or tray feeder to be attached to the feeder table, whether or not to use a transfer unit, and whether or not to use an electrical characteristic measuring device.

[0072] 8, when the SIM setting button 41c in the menu selection area 41 is pressed, the display processing unit 17 switches the display unit 12 to a simulation setting (floor setting) screen 59 (FIG. 9). When switching the display unit 12 to the simulation setting (floor setting) screen 59 (FIG. 9), the display processing unit 17 transmits information on the virtual production line set on the line setting (equipment addition) screen 47 and the line setting (equipment option) screen 54 to the production capacity management device 7 of the support center S.

[0073] In the production capacity management device 7 that has received the command, the virtual capacity setting unit 32 sets the virtual capacity information 22 of the virtual production line based on the received virtual production line information, the virtual capacity information 22 of the existing production lines L1 to L3 stored in the storage device 20, and the standard capacity information 23. In this manner, the number of production devices (component mounting devices) and the equipment elements required to produce the product (electronic circuit board B) owned by the production devices are input from the input unit 11 (input / output terminal device) of the production management device 3. The virtual capacity setting unit 32 sets the virtual capacity information 22 of the virtual production line based on the information input by the input unit 11. In addition, the virtual capacity setting unit 32 sets the virtual capacity information 22 of the virtual production line based on the virtual capacity information 22 of the multiple production lines L1 to L3.

[0074] Next, an example of a simulation setting (floor setting) screen 59 will be described with reference to Fig. 9. The simulation setting (floor setting) screen 59 is used when setting simulation conditions for estimating the production capacity of a floor including a virtual production line. The simulation setting (floor setting) screen 59 is provided with a menu selection area 41, a step switching area 60, an existing floor selection area 61, and a new floor setting area 62.

[0075] The step switching area 60 is arranged with a simulation name input field 60a, a step display frame 60b, a previous button 60c, and a next button 60d. The name of the simulation to be newly created (new simulation (1)) is input in the simulation name input field 60a. The step display frame 48b displays the simulation setting work in the order of steps. When the previous button 60c or the next button 60d is operated, the display switches to the line setting screen for the previous step or the next step.

[0076] In FIG. 9, an existing floor selection area 61 includes an existing floor selection frame 63 and an existing floor information display frame 64. In the existing floor selection frame 63, floors F1 to F3 equipped with existing production lines that are used as a comparison source when estimating the production capacity of a virtual production line are selected from a drop-down list. In this example, floor F1 is selected. In the existing floor information display frame 64, configuration information of the production lines L1 to L3 equipped on the selected floor F1 is displayed. The configuration information of the production lines L1 to L3 includes the line name, CPH, total number of component mounting devices (devices), total number of stages (stages), whether the transport conveyor is dual or single (lane), whether the mounting mode is alternate mounting mode or independent mounting mode (mounting), whether the production method is both lanes or one lane (production), and the like.

[0077] 9, the new floor setting area 62 has an add new line button 65 and a new floor information display frame 66. The new floor information display frame 66 displays the configuration of the new floor including a virtual production line for estimating production capacity. The configuration information of the production line is the same as that of the existing floor information display frame 64. When the delete button arranged in the new floor information display frame 66 is pressed, the corresponding production line is deleted from the configuration of the new floor.

[0078] When the add new line button 65 is pressed, a screen for selecting a virtual production line to be added to the new floor and existing production lines L1 to L3 is displayed (not shown). When a production line is added, configuration information of the added production line is displayed in a new floor information display frame 66. In this example, the new floor is set with the existing production line L1 (line L1), a virtual production line (line L2+D3) in which one component mounting device (D3) has been added to the existing production line L2, the existing production line L3 (line L3), and a virtual production line (new line LX).

[0079] In FIG. 9, when the next button 60d is pressed, the display processing unit 17 displays a simulation setting (production performance selection) screen (not shown) on the display unit 12. In the simulation setting (production performance selection) screen, an electronic circuit board B (product) to be produced on the new floor is set as a condition for estimating production capacity. This electronic circuit board B is selected from electronic circuit boards B with production performance included in the virtual capacity information 22. At that time, the production order of the type of electronic circuit board B (product) is also set. In this way, by selecting from electronic circuit boards B with production performance, it is possible to reduce the effort of setting details of the configuration information of the electronic circuit board B in order to estimate production capacity.

[0080] When the Next button 60d is pressed on the simulation setting (production performance selection) screen, the display processing unit 17 causes the display unit 12 to display a simulation setting (condition setting) screen (not shown). On the simulation setting (condition setting) screen, the number of electronic circuit boards B (products) to be produced, the production time, the mounting mode of each production line, the production method, the number of operators in charge of the new floor, etc. are set. The number of operators is specified for each floor, and during the simulation, the estimation unit 33 allocates the operators to each production line in a predetermined procedure. For example, the estimation unit 33 allocates the number of operators by simply dividing the number of production lines, or by weighting it by the number of production devices each production line has.

[0081] When the Next button 60d is pressed on the simulation setting (condition setting) screen, the display processing unit 17 displays a simulation setting (execution) screen (not shown) on the display unit 12. A start button for starting a simulation that specifies a production capacity is arranged on the simulation setting (execution) screen. When the start button is pressed, the display processing unit 17 transmits configuration information of the new floor, simulation condition information, and the like to the production capacity management device 7 of the support center S.

[0082] In the production capacity management device 7 that has received the information, the estimation unit 33 estimates the virtual production capacity 24 of the virtual production line included in the new floor and the existing production lines L1 to L3 based on the received information and the virtual capacity information 22 of the virtual production line and the existing production lines L1 to L3 stored in the storage device 20. When the estimation of the virtual production capacity 24 is completed, the display information generation unit 34 generates display information 15 (simulation results) to be displayed on the display unit 12 of the transmission source production management device 3, and transmits it to the transmission source production management device 3. When the display information 15 is received, the display processing unit 17 causes the display unit 12 to display the simulation setting (display) screen 67 (FIG. 10).

[0083] Next, an example of a simulation setting (display) screen 67 will be described with reference to Fig. 10. The simulation setting (display) screen 67 has a menu selection area 41, a step switching area 60, and a simulation result display area 68. The simulation result display area 68 has a simulation result display frame 69 and a line-by-line display button 70 arranged therein. The simulation result display frame 69 displays the estimated result (#1) of the virtual production capacity 24 based on the performance of the current floor F1, the estimated result (#2) of the virtual production capacity 24 serving as the comparison source in which the production time is adjusted to the conditions of the new floor with the configuration of the current floor F1, the estimated result (#3) of the virtual production capacity 24 of the new floor to be compared, and the comparison results between the comparison source and comparison target.

[0084] In the simulation result display frame 69 shown in FIG. 10, the estimated results of the production lines are displayed in a form of summation by floor. That is, the display unit 12 displays the virtual production capacity 24 by floor having a plurality of production lines. When the line-by-line display button 70 is pressed, the simulation result display frame 69 displays the estimated results for each production line before summation. In the display information of the simulation result display frame 69, the "catalog CPH" is the value of CPH under ideal conditions where there is no production stop due to resupply work, recovery work, etc. The "floor opening and closing time" is the time from the start of production to the end of production on the floor. The "line opening and closing time" is the sum of the time from the start of production to the end of production on each production line. The "line operating rate" is the percentage of time that each production line is operating without stopping. It is also possible to display on one display screen without having the line-by-line display button 70.

[0085] "Floor CPH" is the CPH value taking into consideration the configuration of electronic circuit board B and production stoppages due to supply work, recovery work, etc. "Area productivity" is the floor CPH per unit floor area. "Number of setup parts" is the number of parts that require setup changeover. "Number of setup carts" is the number of carts that require setup changeover. Simulation result display frame 69 also displays the number of carts required for production (number of resource carts), the number of operators required on the floor, the total time for operator work, etc.

[0086] In this way, the display unit 12 displays information related to the virtual production line, such as the configuration of the virtual production line (FIGS. 7 and 8), virtual capacity information 22 of the virtual production line (FIG. 7), and virtual production capacity 24 of the virtual production line (FIG. 10). The production capacity management device 7 also includes an acquisition unit 30 that acquires device information and operation records 14 of the production devices (component mounting devices), a virtual capacity generation unit 31 that generates virtual capacity information 22 of the production lines L1 to L3 from the device information and operation records 14, and a storage unit (storage device 20) that stores the virtual capacity information 22 for each operation record. This makes it possible to easily generate information (virtual capacity information 22) used to estimate the production capacity of the production lines L1 to L3 with different configurations.

[0087] Next, a production capacity estimation method (production capacity estimation program) for estimating the production capacity of electronic circuit boards B (products) produced by production lines L1 to L3 composed of multiple component mounting devices (production devices) will be described along the flows of Figures 11 and 12. First, virtual capacity information 22 of the production line is generated (ST1: virtual capacity information generation process).

[0088] 12, in a virtual capacity information generating step (ST1), the acquiring unit 30 acquires the device information and operation records 14 of the multiple component mounting devices M6-M9 (production devices) that configure the existing production lines L1-L3 (ST11: acquiring step). Next, the virtual capacity generating unit 31 generates virtual capacity information 22 of the production lines L1-L3 from the device information and operation records 14, including information on the equipment elements of the component mounting devices M6-M9, information on the specifications of the component mounting devices M6-M9, information on the time required for the production lines L1-L3 to produce the electronic circuit board B (product), and information on the events that require the operator's work on the production lines L1-L3 and their occurrence frequency (ST12: virtual capacity information generating step).

[0089] Next, the virtual capacity generation unit 31 stores the generated virtual capacity information 22 in the storage device 20 (storage unit) for each operation record (ST13: storage step). Next, the acquisition step (ST11), virtual capacity information generation step (ST12), and storage step (ST13) are repeatedly executed until the virtual capacity information 22 of all the production lines L1 to L3 is generated (No in ST14). In this way, the acquisition step (ST11), virtual capacity information generation step (ST12), and storage step (ST13) constitute a production capacity management method (production capacity management program) by the production capacity management device 7. The production capacity management method makes it possible to easily generate information (virtual capacity information 22) used to estimate the production capacities of the production lines L1 to L3 having different configurations.

[0090] 11, when virtual capacity information 22 of production lines L1 to L3 is generated (Yes in ST14), the display processing unit 17 receives input from the input unit 11 of information such as the number of component mounting devices (production devices) constituting the virtual production line, the equipment elements of the component mounting devices, and information on the electronic circuit boards B (products) produced in the virtual production line (ST2: information input step) (FIGS. 7 to 9). Next, the virtual capacity setting unit 32 sets the virtual capacity information 22 of the virtual production line based on the information input in the information input step (ST2) (ST3: virtual production line setting step).

[0091] Next, the estimation unit 33 estimates the virtual production capacity 24 of the virtual production line based on the virtual capacity information 22 of the virtual production line, and estimates the virtual production capacity 24 of the production lines L1 to L3 based on the virtual capacity information 22 of the existing production lines L1 to L3 (ST4: virtual production capacity estimation step). Next, the display processing unit 17 displays the estimated virtual production line and the virtual production capacity 24 of the existing production lines L1 to L3 on the display unit 12 (ST5: virtual production capacity display step) (FIG. 10).

[0092] When changing the configuration of the virtual production line or the simulation conditions (Yes in ST6), the information input step (ST2), the virtual production line setting step (ST3), the virtual production capacity estimation step (ST4), and the virtual production capacity display step (ST5) are repeatedly executed. This makes it possible to easily estimate the production capacity of a production line (virtual production line) with a different configuration.

[0093] As described above, the production system 1 of this embodiment is a production capacity estimation system that includes an acquisition unit 30 that acquires equipment information and operation records 14 of a plurality of production devices (component mounting devices), a virtual capacity generation unit 31 that generates virtual capacity information 22 of the production lines L1 to L3 from the equipment information and operation records, the virtual capacity information 22 including information on the equipment elements of the production devices, information on the specifications of the production devices, information on the time required for the production lines L1 to L3 to produce the products (electronic circuit boards B), and information on events that require operator work on the production lines L1 to L3 and information on their occurrence frequency, an estimation unit 33 that estimates virtual production capacities 24 of the production lines L1 to L3 based on the virtual capacity information 22, and a display unit 12 that displays the virtual production capacity 24.

[0094] This makes it possible to easily estimate the production capacity of a production line with a different configuration (a virtual production line).

[0095] In the above embodiment of the production system 1 (production capacity estimation system), the support center S (production capacity management device 7) is installed outside the factory having floors F1 to F3, but the support center S (production capacity management device 7) may also be installed inside the factory.

[0096] In the above, an example has been described in which the production system 1 includes the production lines L1-L3 that mount components D on the boards 10A, 10B to produce the electronic circuit board B, but the production lines L1-L3 included in the production system 1 are not limited to this. For example, the production line may be a semiconductor production line that manufactures semiconductors, an assembly production line that assembles workpieces (products) such as electric machinery and equipment, general machinery and equipment, or a food processing line that produces processed food products. [Industrial Applicability]

[0097] The production capacity estimation system, production capacity estimation method, and production capacity estimation program of the present invention have the effect of easily estimating the production capacity of production lines with different configurations, and are useful in the component mounting field in which components are mounted on boards.
