In the component mounting line L1, production equipment including a transport unit 5 that transports substrates (workpieces) from the upstream side to the downstream side are connected to each other. The transport sections 5 connected to each other in the component mounting line L1 constitute a front transport lane 5F on the front side and a rear transport lane 5R on the rear side. That is, the component mounting line L1 includes a front transport lane 5F (first transport lane) and a rear transport lane 5R (second transport lane) in parallel.

The substrate transported to the substrate supply device M12 is stored in the substrate supply device M12 with its surface facing up. The board (single-sided mounting board) supplied from the board supply device M12 is turned upside down by the board reversing device M13 on the downstream side, so that the back side is facing up. The inverted board is transported along the rear transport lane 5R, and parts are mounted on the back surface of the board, and the board is collected by the board collection device M17 (arrow f).

Information regarding the working time (equipment takt time), the frequency of occurrence of equipment errors (occurrence probability), etc. is stored. Note that the frequency of occurrence (probability of occurrence) of device errors is a value set based on expected values and actual values.

Here, with reference to FIG. 5, an example of the transport unit selection screen 20 displayed on the display screen 17a of the display unit 17 by the method selection processing unit 11 when setting the transport route in the component mounting lines L1 to L4 will be described. . The transport section selection screen 20 includes a production line data selection area 21, a line selection area 22, a line configuration display area 23, a clear button 24, and an end button 25. When the production line data selection area 21 is operated using the input unit 16, information (production line data name) specifying the production line data to be created is selected or input. When the line selection area 22 is operated using the input unit 16, the component mounting lines L1 to L4 displayed in the line configuration display area 23 are selected. Here, component mounting line L1 is selected.

In the line configuration display area 23, the configuration of the component mounting line L1 is schematically displayed, and radio buttons 23a for selecting the transport section 5 to which the board is to be transported are displayed for each production facility. When the radio button 23a is operated using the input unit 16, setting (white circle) or non-setting (blank field) of the transport unit 5 is selected. In the example of FIG. 5, a transport route is set, which is indicated by an arrow f in FIG. 3, for transporting the substrate from the substrate supply device M12 to the substrate recovery device M17 in the rear transport lane 5R.

In FIG. 5, when the clear button 24 is operated using the input unit 16, all the radio buttons 23a displayed in the line configuration display area 23 are unset. When the end button 25 is operated using the input unit 16, the setting of the transport route on the transport unit selection screen 20 is completed, and the data creation unit 12 stores the information set in the line configuration display area 23 as production plan data 14c. The information is stored in the unit 14.

In this way, the transport section selection screen 20 is displayed on the display screen 17a, and is a method selection means for selecting at least one transport section 5 from a plurality of transport sections 5 of a production facility including a plurality of transport sections 5 in parallel. By using the transport section selection screen 20, it is possible to easily specify how the workpiece (substrate) is transported. In addition, in the line configuration display area 23, a production equipment group is defined as a configuration in which a plurality of production equipment having a plurality of conveyance units 5, such as from the component mounting device M4 to the conveyor device M7, are lined up adjacently. When the radio button 23a of one production facility is selected, all the radio buttons 23a of the selected transport lane may be selected.

For example, if you select the radio button 23a of the transport section 5 on the rear side of the component mounting apparatus M5, the radio button 23a of the transport section 5 on the rear side of the component mounting apparatus M4, the component mounting apparatus M6, and the conveyor apparatus M7 that constitute the production equipment group is selected. 23a is selected together. That is, in a production line (component mounting lines L1 to L4) including production equipment having a plurality of transport units 5 and production equipment having one transport unit 5, the method selection means (transport unit selection screen 20) A configuration in which a plurality of production facilities having transport units 5 of 1 and 5 are lined up adjacently is defined as a production facility group, and a transportation method for the production facility group is selected.

Here, with reference to FIG. 6, an example of the transport method set on the transport unit selection screen 20 will be described. In FIGS. 6(a) to 6(d), only the line configuration display area 23 is displayed. In FIG. 6(a), a LotA mounted board is produced in the front transport lane 5F from the board supply device M1 to the board recovery device M11, and a LotB mounted board is produced in the rear transport lane 5R from the board supply device M12 to the board recovery device M17. This is a transportation method for producing different types of mounting boards. When producing a double-sided mounting board, in the transport method shown in FIG. 6A, components are mounted on the front surface of the board as Lot A, and components are mounted on the back surface of the board as Lot B.

In FIG. 6(b), a Lot A mounted board is produced in the front transport lane 5F from the board supply device M1 to the board recovery device M11, and a Lot A mounted board is produced in the rear transport lane 5R from the board supply device M12 to the board recovery device M17. This is a transportation method that produces printed circuit boards of the same type. In FIG. 6(c), the substrates of Lot A supplied from the substrate supply device M12 are distributed to the front transfer lane 5F and the rear transfer lane 5R by the substrate distribution device M3, and are recovered by the substrate recovery device M11 and the substrate recovery device M17. This is a transportation method that produces mounted boards of the same model.

In FIG. 6(d), the substrates of Lot A are supplied from the substrate supply device M1 and transported to the conveyor device M7 by the front transport lane 5F, and are distributed to the rear transport lane 5R by the substrate sorting device M8 and collected by the substrate recovery device M17. This is a transport system for producing mounted boards of the same type, in which the mounted boards of Lot A are produced in the rear transport lane 5R from the board supply device M12 to the board recovery device M17.

Next, with reference to FIG. 7, an example of the transport method selection screen 30 displayed on the display screen 17a of the display unit 17 by the method selection processing unit 11 when setting transport routes in the component mounting lines L1 to L4 will be described. . The transport method selection screen 30 differs from the transport unit selection screen 20 in which a transport unit 5 is selected for each production facility in that a transport method is set for each component mounting line L1 to L4. The transport method selection screen 30 includes a production line data selection area 31, a transport method setting area 32, and an end button 33. When the production line data selection area 31 is operated using the input unit 16, information (production line data name) specifying the production line data to be created is selected or input.

The transport method setting area 32 includes a "line number" column 32a and a "transport method" column 32b. Line numbers identifying the component mounting lines L1 to L4 are displayed in the "line number" column 32a. The "conveyance method" column 32b displays a conveyance method (same model, different model, etc.) corresponding to the line number. When the "transport method" field 32b is operated using the input unit 16, a drop-down list 32c is displayed, and a transport method selectable for the component mounting lines L1 to L4 can be selected.

For example, if "different model" is selected in the "transport method" column 32b for the line number "L4", the transport method of the different model shown in FIG. 6(a) is selected as the transport method for the component mounting line L4. Furthermore, when "same model" is selected, the same model transport method shown in FIG. 6(b) is selected as the transport method for the component mounting line L1. When the end button 33 is operated using the input unit 16, the setting of the transport method on the transport method selection screen 30 is completed, and the data creation unit 12 stores the information set in the transport method setting area 32 as production line data 14c as a production plan. The information is stored in the unit 14.

In this way, the transport method selection screen 30 is displayed on the display screen 17a, and is used to select a plurality of works ( This is a method selection means for selecting a transportation method for production equipment based on whether the types of substrates (substrates) are the same (same model) or different (different models). Then, the data creation unit 12 creates production line data 14c including information regarding the transport route of the workpiece in the production line based on the transport method selected by the method selection means. By using the transport method selection screen 30, it is possible to easily specify the method of transporting the workpiece (substrate).

In FIG. 4, the production time calculation unit 13 calculates lot information 14a, lot information 14a, It has a function of calculating the time until the lot production is completed (lot production time) when producing the planned lot production amount of the mounting board specified by the product type information 14b. The production time calculation unit 13 starts from the substrate supply devices M1 and M12, performs production work in the device takt time in each production facility while delivering the substrate to the downstream side, until the substrate is recovered by the substrate recovery devices M11 and M17. The production situation is simulated and the lot production time is calculated.

At this time, the production time calculation unit 13 predicts the time during which the production equipment will stop due to component replenishment work based on component consumption in the component mounting machines M4 to M6 and recovery work based on the probability (frequency) of occurrence of equipment errors. Add to lot production time. In this way, the production time calculation unit 13 calculates the time required to complete production of a lot (lot production time).

In addition, in the calculation of the lot production time by the production time calculation unit 13, in the transport method for producing the same model (Lot A) shown in FIGS. The production amount (distribution ratio) of mounted boards can be set arbitrarily. For example, the distribution ratio between the front conveyance lane 5F and the rear conveyance lane 5R may be set to 50% and 50% in the conveyance system shown in FIG. 6(b), or the distribution ratio may be set to 40% in the conveyance system shown in FIG. 6(d). %, it can also be set to 60%. In addition, in the transport method for producing the same model, the board sorting device M3 can be set to automatically distribute to the front transport lane 5F or the rear transport lane 5R depending on the production status of the component mounting devices M4 to M6 in the simulation. can.

In this way, the lot production time calculated (estimated) by the production time calculation unit 13 varies depending on the transport method (transport route) in the component mounting lines L1 to L4. In addition, when the component mounting lines L1 to L4 are equipped with multiple lanes (front transfer lane 5F, rear transfer lane 5R), lot production time varies depending on the distribution ratio of substrates (workpieces) to be transferred to each lane. . In the production control device 4, the optimum transport method can be determined by changing the transport method on the transport unit selection screen 20 or transport method selection screen 30 and repeating calculation of lot production time while changing the distribution ratio. can.

Next, a production time calculation method (production management method) for calculating lot production time using the production management device 4 will be explained along the flow shown in FIG. First, using the transport section selection screen 20 or the transport method selection screen 30, the transport method of the production equipment constituting the component mounting lines L1 to L4 (production lines) is selected (ST1: transport method selection step). On the transport unit selection screen 20, at least one transport unit 5 is selected from a plurality of transport units 5 of a production facility including a plurality of transport units 5 in parallel (see FIG. 5). On the transport method selection screen 30, a transport method is selected based on whether the types of multiple boards (workpieces) to be transported in parallel on component mounting lines L1 to L4 are the same (same model) or different (different models). (See Figure 7).

When the transport method is selected, the data creation unit 12 creates production line data 14c including information regarding the transport route of the board (work) in the component mounting lines L1 to L4 (production line) based on the selected transport method. Create (ST2: Production line data creation department). When producing the same lot by distributing it to a plurality of lanes of component mounting lines L1 to L4, a distribution ratio is then set (ST3: distribution ratio setting step).

Next, the production time calculation unit 13 calculates the time until the production of the lot is completed (the lot production time ) is calculated (ST4: lot production time calculation step). In this way, the production control method of the present embodiment can easily specify the flow of the workpiece (substrate), and can accurately simulate the lot production time.

As described above, the production control device 4 of the present embodiment includes the display section 17 having the display screen 17a, and the production line (component mounting line L1) that is displayed on the display screen 17a and processes a plurality of works (boards). - L4) for selecting the transport method of the production equipment (transport unit selection screen 20, transport method selection screen 30) It includes a data creation unit 12 that creates production line data 14c including information regarding the transport route. This makes it possible to easily specify how the workpiece flows.

Note that in the present embodiment described above, a transport method is selected (set) for each lot of mounted substrates, but the present invention is not limited to this. As another modification, the production line data 14c may be created in which the transport method of the production equipment is set for a lot of a plurality of mounted board models. In this case, the same transport method may be set for the board types of the plurality of mounting boards, or the transport method may be changed depending on the board type of the mounting boards.

Furthermore, as will be described later, production line data 14c may be created in which the transport method is changed for each predetermined number of sheets. That is, when producing double-sided mounting boards on one component mounting line L1 to L4, first a predetermined number of single-sided mounting boards with components mounted on the front surface are produced using a plurality of transport lanes. Thereafter, components are mounted on the back side of the single-sided mounting board in one transport lane, and production of the single-sided mounting board is continued in the other transport lane. Then, after the production of the single-sided mounting board is finished, components may be mounted on the back side of the single-sided mounting board in the other transport lane as well.

In other words, a different transport method is set for each predetermined number of target mounted boards (for example, the 1st to 100th board is of the same model, the 101st to 400th board is of a different model, and the 401st board is of a different model. (For example, set the transport method of the same model for the 500th sheet.) By setting the transport method in this way, it is possible to accurately simulate the lot production time.

The above description has been based on one embodiment of the present invention. It will be understood by those skilled in the art that this embodiment allows various modifications to the types and combinations of products (works) produced (processed) on the production line, and that such modifications are also within the scope of the present invention.
