The tape feeder 7 and the tray feeder are component supply devices that supply the component D to the component take-out position. Whether the tape feeder 7 or the tray feeder is disposed as a component supply device in the component supply unit 6 is freely changed according to the type and size of the component D to be supplied.

  At one end of the upper surface of the base 4 in the X direction, a Y-axis beam 8 having a linear drive mechanism is provided along the Y direction. To the Y-axis beam 8, two X-axis beams 9 similarly having a linear drive mechanism are movably coupled in the Y direction. The X-axis beam 9 is provided along the X direction.

A suction nozzle (not shown) is attached to each end of the suction unit 10a.

  The mounting heads 10 are prepared in different types with different numbers of suction units 10a and different shapes and sizes of the suction units 10a. The mounting heads 10 can be freely replaced and mounted on the X-axis beam 9. If the number of the provided suction units 10a is large, the number of components D that can be simultaneously suctioned to the mounting head 10 increases, so that the component mounting time can be reduced. When a large component D is to be sucked, the mounting head 10 having a small number of suction units 10a and a large size of the suction unit 10a is used. As described above, the type of the mounting head 10 mounted on the component mounting apparatus M3 is freely selected according to the type and size of the component D to be sucked.

  In FIG. 2, by driving the Y-axis beam 8 and the X-axis beam 9, the mounting head 10 moves in the X and Y directions. As a result, the two mounting heads 10 pick up the component D from the component pick-up position of the tape feeder 7 arranged in the corresponding component supply unit 6 by sucking and picking up the component D with the suction nozzle, and then mount the board B positioned on the board transport mechanism 5. Implement at the implementation point of.

  A component recognition camera 11 is provided between the component supply unit 6 and the board transport mechanism 5. When the mounting head 10 that has taken out a component from the component supply unit 6 moves above the component recognition camera 11, the component recognition camera 11 images the component D held by the mounting head 10 and holds the component D in a holding posture. Recognize. The board recognition camera 12 is attached to the plate 9a to which the mounting head 10 is attached. The board recognition camera 12 moves integrally with the mounting head 10.

  As the mounting head 10 moves, the board recognition camera 12 moves above the board B positioned by the board transport mechanism 5 and picks up an image of a board mark (not shown) provided on the board B to capture the position of the board B. Recognize. In the component mounting operation on the board B by the mounting head 10, the mounting position is corrected in consideration of the recognition result of the component D by the component recognition camera 11 and the recognition result of the board position by the board recognition camera 12.

  As described above, in the component mounting apparatus M3, the board transport mechanism 5, the component mounting mechanism (Y-axis beam 8, X-axis beam 9, mounting head 10), component recognition camera 11, and board recognition camera 12 transport the board B.

  In FIG. 3, the mounting data 32a is data such as the component type of the component D to be mounted and the mounting point on the board B, and is stored for each board type (mounting board) to be produced. The production plan information 32b (information on the production plan) includes the type and number of mounting boards produced in the component mounting line L, which are planned in the component mounting system 1 for a predetermined period (for example, six months). The production plan is stored.

  The current equipment configuration information 32c (information on the current equipment configuration) stores the equipment configuration (current equipment configuration) of the component mounting apparatuses including the component mounting apparatuses M3 to M6, which constitute the current component mounting line L. I have. The new equipment configuration information 32d stores the equipment configuration (new equipment configuration) of the component mounting apparatus changed from the current component mounting line L by the equipment configuration changing unit 31d. The equipment configuration stored in the current equipment configuration information 32c and the new equipment configuration information 32d includes the type of the mounting head 10 mounted on the component mounting apparatuses M3 to M6, the tape feeder 7 mounted on the component supply unit 6, the tray feeder, and the like. The type of the component supply device is included. The change in the equipment configuration by the equipment configuration changing unit 31d includes a change in the type of the mounting head 10 of the component mounting apparatuses M3 to M6 and a change in the component supply device.

  In FIG. 3, the production time prediction unit 31a calculates the number of sheets planned by the component mounting line L having a predetermined facility configuration based on the mounting data 32a, the production plan information 32b, the current facility configuration information 32c, and the new facility configuration information 32d. The production time Tp required to produce the mounting board is calculated (predicted) for each mounting board. The calculated production time Tp is stored in the management storage unit 32 as production time information 32e.

  The equipment operation rate prediction unit 31b calculates an equipment operation rate Ro, which is a ratio of an operation time during which the component mounting line L is producing a mounting board to a time during which power is supplied to the component mounting line L. The time during which power is supplied to the component mounting line L but the mounting board is not being produced (non-operation time) includes a setup change time Tc required for setup change for changing the type of the production board, a maintenance time, and the like. . The equipment operation rate prediction unit 31b calculates the setup change time Tc generated in the component mounting line L having a predetermined equipment configuration based on the mounting data 32a, the production plan information 32b, the current equipment configuration information 32c, and the new equipment configuration information 32d. Calculated (predicted) for each replacement. The maintenance time is predicted based on past production records (production logs) and the like. The calculated facility operating rate Ro is stored in the management storage unit 32 as facility operating rate information 32f.

  Based on the mounting data 32a, the production plan information 32b, the current equipment configuration information 32c, and the new equipment configuration information 32d, the workforce prediction unit 31c cooperates with the production time prediction unit 31a and the equipment operation rate prediction unit 31b to mount components. The average number of workers per day (hereinafter, referred to as the number of workers No.) required for setup work, parts supply work, maintenance work, and the like occurring on the line L is calculated (predicted). The calculated number of workers No. is stored in the management storage unit 32 as the number of workers information 32g.

  In FIG. 3, a cost reduction target when changing the equipment configuration of the component mounting line L from the current equipment configuration to the new equipment configuration is input from the input unit 33 to the cost reduction target information 32h (information on the cost reduction target). Is remembered. The cost unit price information 32i includes the device operating cost per unit time when producing a mounting board on the component mounting line L having a predetermined facility configuration, the labor cost of an operator, the component mounting device, the mounting head 10, the component supply device. The purchase cost, the relocation cost, the installation cost, and the floor construction cost necessary for changing the equipment configuration are stored.

  The equipment stop time information 32j includes the time required when changing the equipment configuration of the component mounting line L from the current equipment configuration to the new equipment configuration, that is, the equipment stop time Ts when the equipment is stopped and the equipment configuration is changed. Is stored. The equipment stop time Ts is calculated when the equipment configuration is changed by the equipment configuration changing unit 31d.

  In FIG. 3, the cost calculation unit 31e is based on current equipment configuration information 32c, new equipment configuration information 32d, production time information 32e, equipment operation rate information 32f, number of workers 32g, cost unit price information 32i, and equipment stop time information 32j. Then, the total cost Cs including the production cost Cp, the change cost Cc, and the production cost Cp and the change cost Cc is calculated. The production cost Cp is a cost incurred when producing a mounting board within a specific period on the component mounting line L having a predetermined equipment configuration (current equipment configuration, new equipment configuration). The change cost Cc is a cost generated by changing the equipment configuration from the current equipment configuration (current equipment configuration) to a new equipment configuration (new equipment configuration).

  The cost calculation unit 31e calculates, as the production cost Cp, the production time Tp calculated by the production time prediction unit 31a based on a predetermined equipment configuration, the equipment operation rate Ro calculated by the equipment operation rate prediction unit 31b, and the number of workers prediction unit 31c. The total cost Cs is calculated in consideration of at least one of the number of workers No. The cost calculation unit 31e calculates the total cost Cs in consideration of the equipment stop time Ts when the equipment configuration is changed as the change cost Cc. The calculated production cost Cp, change cost Cc, and total cost Cs are stored in the management storage unit 32 as calculated cost information 32k.

  When calculating the total cost Cs, the cost calculation unit 31e calculates any one of the production time Tp, the equipment operation rate Ro, the number of workers No, and the equipment stop time Ts as variable values, The cost may be calculated with the item (1) as a fixed value. For example, the total cost Cs may be calculated by changing the number of workers (the number of workers No) before and after the change, and changing only the other items. The operator can set items to be treated as fixed values and the fixed values using the input unit 33 of the management computer 3.

  The cost determination unit 31f calculates the reduction amount of the total cost Cs by changing the equipment configuration of the component mounting line L from the current equipment configuration to the new equipment configuration based on the cost reduction target information 32h and the calculated cost information 32k. It is determined whether or not is satisfied. That is, the cost determining unit 31f determines whether the total cost Cs of the new facility configuration (new facility configuration) is reduced more than the cost reduction target as compared with the current facility configuration (current facility configuration). When the cost reduction target is not set, the cost determination unit 31f determines whether or not the new equipment configuration reduces the total cost Cs from the current equipment configuration.

  Here, the production cost Cp, the change cost Cc, the total cost Cs calculated by the cost calculation unit 31e, and the reduction judgment of the total cost Cs by the cost determination unit 31f will be described with reference to FIG. FIG. 4 shows that the production within a specific period of 6 months is performed by the current equipment configuration and the component mounting lines L of three new equipment configurations (1) to (3) changed from the current equipment configuration by the equipment configuration changing unit 31d. An example of the cost incurred in doing so is shown.

  In FIG. 4, the total cost Cs in the current equipment configuration does not include the change cost Cc, and the total cost Cs is all the production cost Cp. The production time Tp required for the production of the mounting board planned for six months, which is considered in the calculation of the production cost Cp of the current equipment configuration, is predicted to be 3600 hours by the production time prediction unit 31a, and the equipment operation rate Ro is The equipment operation rate prediction unit 31b predicts the number of workers to be 85%, and the number of workers No. is predicted by the number of workers prediction unit 31c to be 15 persons / day. The cost calculator 31e calculates the production cost Cp (total cost Cs) based on these predictions.

  Similarly, the production time Tp required to produce a mounting board planned for six months in the current facility configuration in the new facility configuration (1), the new facility configuration (2), and the new facility configuration (3) is 3600. Time, 3400 hours, 3500 hours, the equipment operation rate Ro is predicted to be 90%, 95%, 90%, and the number of workers is predicted to be 13 / day, 12 / day, and 14 / day. The production costs Cp for the new equipment configuration (1), the new equipment configuration (2), and the new equipment configuration (3) are calculated based on these predictions.

  In the new equipment configurations (1) to (3), the change cost Cc is also calculated by the cost calculator 31e. The change cost Cc includes a device introduction cost and an opportunity loss cost. The cost calculation unit 31e calculates the total cost of the equipment purchased, the relocation of the equipment, and the installation cost when changing from the current equipment configuration to the new equipment configuration (1) to (3) based on the cost unit price information 32i. Calculate as the introduction cost.

  In addition, based on the equipment stoppage time Ts, the cost calculation unit 31e stops the equipment when changing from the current equipment configuration to the new equipment configurations (1) to (3) and cannot produce any profit. Is calculated as the opportunity loss cost. That is, the opportunity loss cost is a virtual benefit of a mountable substrate that can be produced when the production is performed for the facility stop time Ts without changing the facility configuration from the current facility configuration. The cost calculation unit 31e calculates the change cost Cc including the device introduction cost and the opportunity loss cost, and adds the change cost Cc to the production cost Cp to calculate the total cost Cs.

  In FIG. 4, in the new equipment configuration (1), it is assumed that the production cost Cp is reduced by an amount corresponding to the reduction in the number of workers No., and the total cost Cs can be reduced from the current equipment configuration. Is predicted. However, cost reduction goals have not been met. In the new equipment configuration (2), it is predicted that the work speed and the automation of the work are improved as compared with the current equipment configuration, and the production cost Cp is reduced by the reduction of the production time Tp and the number of workers No. However, the equipment introduction cost and the opportunity loss cost are large, and the change cost Cc is large, and it is predicted that the total cost Cs for the specific period of 6 months will be larger than the current equipment configuration.

  In the new equipment configuration (3), it is predicted that the operation speed and the automation of the work are improved as compared with the current equipment configuration, and the production cost Cp is reduced by the reduction of the production time Tp and the number of workers No. Moreover, since the change cost Cc required for this improvement is smaller than that of the new equipment configuration (2), it is predicted that the total cost Cs will be reduced as compared with the current equipment configuration, and that the cost reduction target will be satisfied. The cost determination unit 31f compares the total cost Cs of the current facility configuration with the total cost Cs of the new facility configurations (1) to (3), and determines whether the reduction of the total cost Cs satisfies the cost reduction target. I do. In this example, the new facility configuration (3) satisfies the cost reduction target, and the new facility configuration (3) is determined as a new facility configuration.

  As described above, the equipment configuration change unit 31d, the cost calculation unit 31e, and the cost determination unit 31f perform the production within the specific period on the component mounting line L, compared to the case where the production is continued with the current equipment configuration. It is a facility configuration creating unit that creates a new facility configuration to be reduced. Then, the management computer 3 including the equipment configuration creation unit becomes an equipment configuration creation support system that supports creation of an equipment configuration of the component mounting line L including the component mounting apparatuses M3 to M6.

  The facility configuration creation support system is not limited to the management computer 3 connected to the component mounting line L and the communication network 2. The equipment configuration creation support system only needs to be a computer including an equipment configuration creation unit, and need not be connected to the component mounting line L.

  Next, a facility configuration creation support method for supporting creation of a facility configuration of the component mounting line L including the component mounting apparatuses M3 to M6 will be described with reference to the flow of FIG. First, the current equipment configuration (current equipment configuration) is set (input) (ST1: current equipment configuration setting step). The set current equipment configuration is stored as the current equipment configuration information 32c. Next, a production plan of the mounting board for evaluating the equipment configuration before and after the change is set (ST2: production plan setting step). Specifically, a production plan to be evaluated and a period (specific period) to be evaluated included in the production plan information 32b are specified. Next, a cost reduction target is set (ST3: target setting step). The cost reduction target is input from the input unit 33 and stored as cost reduction target information 32h.

  Next, the cost calculation unit 31e calculates the production cost Cp and the total cost Cs of the component mounting line L in the current equipment configuration, and stores them as calculated cost information 32k (ST4: current cost calculation step). Next, the equipment configuration changing unit 31d changes the equipment configuration from the current equipment configuration to a new equipment configuration (new equipment configuration) (ST5: equipment configuration change step). The change in the equipment configuration includes a change in the type of the mounting head 10 of the component mounting apparatuses M3 to M6 and a change in the component supply device. Thus, it is possible to predict not only the addition and update of the component mounting apparatuses M3 to M6 constituting the component mounting line L, but also the effect of cost reduction by updating the mounting head 10 and the component supply devices (tape feeder 7, tray feeder). Can be. The created new equipment configuration is stored as new equipment configuration information 32d.

  Next, the cost calculation unit 31e calculates the production cost Cp, the change cost Cc, and the total cost Cs in the new equipment configuration (ST6: new cost calculation step). In the new cost calculation step (ST6), the equipment stop time Ts when the equipment configuration is changed is considered as the change cost Cc. Thereby, the opportunity loss cost can be considered.

  In the current cost calculation step (ST4) and the new cost calculation step (ST6), at least one of the production time Tp depending on the equipment configuration, the equipment operation rate Ro, and the number of workers is considered as the production cost Cp. At this time, the production time Tp is calculated (predicted) based on the equipment configuration by the production time prediction unit 31a, the equipment operation rate Ro is calculated by the equipment operation rate prediction unit 31b, and the number of workers No is calculated by the number of workers prediction unit 31c. . As a result, the production cost Cp can be more accurately predicted.

  In FIG. 5, next, the cost determination unit 31f determines whether or not the total cost Cs of the new equipment configuration is reduced more than the cost reduction target as compared with the current equipment configuration (ST7: cost determination step). If the cost reduction target is not set, it is determined in the cost determination step (ST7) whether or not the new equipment configuration reduces the total cost Cs from the current equipment configuration. When the total cost Cs is reduced beyond the cost reduction target (Yes in ST7), the calculated production cost Cp, change cost Cc, and total cost Cs are linked to a new equipment configuration and stored as calculated cost information 32k. (ST8: new cost storage step).

  Next, the facility configuration changing unit 31d determines whether another facility configuration can be changed (ST9: changeable determination step). If the total cost Cs is not reduced beyond the cost reduction target (No in ST7), the changeability determination step (ST9) is executed without executing the new cost storage step (ST8). If another equipment configuration can be changed (Yes in ST9), the process returns to the equipment configuration change step (ST5), and another new equipment configuration is created. Otherwise, when the equipment configuration cannot be changed (No in ST9), that is, after the cost reduction in all the new equipment configurations is considered, the cost determining unit 31f determines the cost based on the stored calculated cost information 32k. The equipment configuration that can be reduced most by the total cost Cs is determined as a new equipment configuration (ST10: new equipment configuration determination step).

  As described above, in the current cost calculation step (ST4) to the new equipment configuration determination step (ST10), the production of the component mounting line L within a specific period is more than the total cost Cs of the production with the current equipment configuration. This is an equipment configuration creation step of creating a new equipment configuration that reduces the number of equipment. That is, the facility configuration creation support method includes a facility configuration creation process, and includes a current facility configuration (information on the current facility configuration), a production plan to be evaluated (information on the production plan), and a cost reduction target (related to the cost reduction target). When (information) is set (ST1 to ST3), a new facility configuration is created in the facility configuration creation step (ST4 to ST10). As a result, it is possible to support creation of a facility configuration that can reduce costs compared to the current component mounting line L.

  As described above, the management computer 3 of the present embodiment is a facility configuration creation support system that supports creation of a facility configuration of the component mounting line L including the component mounting apparatuses M3 to M6. In the production within a specific period, an equipment configuration creating unit is provided for creating a new equipment configuration in which the total cost Cs is reduced as compared with continuing the production with the current equipment configuration. As a result, it is possible to support creation of a facility configuration that can reduce costs compared to the current component mounting line L.

  The equipment configuration creation support system and the equipment configuration creation support method of the present invention have an effect that it is possible to support creation of an equipment configuration capable of reducing costs compared to the current component mounting line, and a component for mounting components on a board Useful in packaging.
