By the way, the production schedule may be changed, for example, the production of a substrate product that was not scheduled for production is required, or the production of a specific substrate product that is scheduled for production is discontinued. In such a case, in order to guide the operator to the setup, it becomes necessary to regenerate the setup list according to the change of the setup contents and the execution timing, and there is a concern that the production time will be extended.

In addition, depending on the production status such as the start time of the production job to be executed next time is approaching, the operating rate of the component mounting machine may decrease if all the scheduled setups are completed. Furthermore, depending on the working conditions of the operator, it may be more efficient to perform the setup that is not currently guided.

The present invention has been made in view of such circumstances, and provides a setup support device capable of editing a setup according to a change in a production schedule or the like to improve the efficiency of the setup of a component mounting machine. The purpose is.

Specifically, in the mounting process, the control device 50 inputs information output from various sensors provided in the component mounting machine 1 and the result of recognition processing by image processing and the like. Then, the mounting control unit 51 sends a control signal to the component transfer device 30 based on the control program, the information from various sensors, and the results of various recognition processes. As a result, the position and rotation angle of the suction nozzle 34 supported by the mounting head 33 are controlled.

(Host computer 60 and various data)
The host computer 60 monitors the operating status of the production line and controls the constituent devices of the production line including the plurality of component mounting machines 1. Further, the host computer 60 totals the degree of progress of production by the component mounting machine 1. The host computer 60 stores various data used for controlling a plurality of component mounting machines 1 constituting the production line. Further, the host computer 60 generates a production schedule and a setup list used for controlling the setup support device 70 described later.

As shown in Table 3 of FIG. 4, the production schedule shows the execution order of production jobs (JobA, JobB, JobC, ...) As the production order of a plurality of types of substrate products. The production schedule is generated based on the production plan (see Table 1 in FIG. 4) and the product data (see Table 2 in FIG. 4). In the present embodiment, the execution order of a plurality of production jobs (JobA, JobB, JobC, ...) indicated by the production schedule is optimized so that the number of setups is reduced with respect to the number of types of production jobs. It is preset by the process.

The above optimization process is ordered so that, for example, when some of the required electronic component parts are common among different product types, multiple types of production jobs corresponding to these product types are executed in succession. Set. This eliminates the need for setup between production jobs for the feeder 23 that supplies a common component type. If the total number of electronic component parts required between different product types is less than or equal to the number of slots 21 of the component supply device 20, a feeder 23 capable of supplying different component types can be set in each slot 21. The number of setups can be reduced.

Specifically, a plurality of types of production jobs (JobA, JobB, JobC) corresponding to product types (U1, U2, U3) are grouped (Gr01). As a result, for the group (Gr01), a plurality of production jobs (JobA to JobC belonging to Gr01) can be executed by one setup (Set1). In addition, the execution order of production jobs is optimized based on the priority of production for each product type. Therefore, the setup (Set3, Set4) may be executed before and after the production job (JobF) without grouping as described above.

As shown in Table 1 of FIG. 4, the above production plan shows the target production quantity (T1, T2, T3, ...) For each product type (U1, U2, U3, ...) Of the substrate product. .. As shown in Table 2 of FIG. 4, the product data includes the product types (U1, Pb, Pc, Pd, ...) And the number of parts of the electronic parts required for the production of the substrate product. It is the data recorded for each U2, U3, ...). In other words, the product data indicates the number of parts consumed when one board product of a predetermined product type is produced for each part type.

As shown in Table 4 of FIG. 4, the setup list makes the production job executable in the component mounting machine 1 among a plurality of production jobs (JobA, JobB, JobC, ...) Included in the production schedule. Indicates one or more production jobs selected for setup. The setup list is, for example, when a plurality of production jobs (JobA to JobE) are selected as the setup targets, or when a group (Gr01, Gr02) corresponding to these production jobs (JobA to JobE) is selected. , A plurality of production jobs (JobA to JobE) are associated with the required setups (Set1 and Set2).

(Setup support device 70)
The setup support device 70 executes various production jobs (JobA, JobB, JobC, ...) For mounting electronic components on the circuit board 90, and performs a plurality of types of board products (U1, U2, U3, ...). It is applied to the component mounting machine 1 that produces the above. The setup support device 70 is communicably connected to a plurality of component mounting machines 1 and a host computer 60 constituting the production line. As shown in FIG. 3, the setup support device 70 includes a storage unit 71, a list editing unit 72, a guide unit 73, a condition editing unit 74, and a preparation trolley 80.

In the present embodiment, the storage unit 71, the list editing unit 72, the guide unit 73, and the condition editing unit 74 are incorporated in the control device provided in the preparation carriage 80. The storage unit 71 is composed of an optical drive device such as a hard disk device, a flash memory, or the like. The storage unit 71 stores various data for controlling setup guidance and the like by the setup support device 70. The storage unit 71 transfers and stores the production schedule (Table 3 in FIG. 4) generated by the host computer 60 and the setup list (Table 4 in FIG. 4) from the host computer 60.

The list editorial unit 72 increases / decreases the production jobs included in the setup list (Table 4 in FIG. 4) in response to the request of the operator who sets up the component mounting machine 1 or the change in the production schedule (Table 3 in FIG. 4). Edit to let. The list editing unit 72 accepts the operator to change the setup list via an input device (not shown). The operator's request includes, for example, a request to add a production job that exists in the production schedule and is not in the current setup list, and a request to delete some production jobs included in the setup list.

In addition, various aspects of the above operator's request are assumed. The list editorial unit 72 displays the current setup list and production schedule, and individually produces jobs (JobA, JobB, JobC, ...), Groups (Gr01, Gr02, ...), Setups (Set1, Set2, ...). (Set3, ...) May be directly specified and accepted as a request for addition and deletion.

Further, the list editorial unit 72 requests that one or a plurality of production jobs that can be started to be executed by a specified time among the plurality of production jobs included in the production schedule (Table 3 in FIG. 4) be set up. If so, edit the setup list at the request of the operator. Specifically, as shown in Table 3 of FIG. 4, the list editing unit 72 is scheduled to be calculated based on the required time (R1, R2, R3, ...) For each production job included in the production schedule. Determine which production job is to be set up based on the start date and time and the specified time entered. The list editing unit 72 edits the setup list so that the indexed one or more production jobs are set up.

Further, with respect to the request by the operator as described above, editing of the setup list may not be permitted due to certain restrictions. Here, when the setup is the replenishment process of the feeder 23, the above-mentioned "certain constraint" includes, for example, a plurality of feeders 23 that can be exchanged for the number of parts used for all the requested production jobs. Includes constraints based on circumstances where not all required setups can be completed due to a shortage of. Therefore, in the present embodiment, the setup support device 70 edits the setup list within a range permitted by certain restrictions among the requests made by the operator.

Specifically, when the operator requests that one or more production jobs be added to the setup target, the list editorial unit 72 of the feeder 23 required for setting up the plurality of production jobs after the addition. Based on the required number and the available number of feeders 23 that can be used at the time of setup guidance, it is determined whether or not the setup list can be edited according to the operator's request. If the setup support device 70 can edit the setup list in response to the request, the setup support device 70 edits the setup support device 70 so as to add one or more production jobs to the setup list in response to the request.

Here, the above-mentioned "necessary number of feeders 23" is the number of feeders 23 required for the setup of all the production jobs to be set up, and increases as the production jobs are added to the setup targets. .. For example, as shown in FIG. 9, when the setup targets are three production jobs (JobA, JobB, JobC), the required number of feeders 23 is the sum of the required numbers (Ev3). When three production jobs (JobD, JobE, JobF) are added as setup targets, the required number of feeders 23 is the sum of the required numbers (Ev6).

Further, the above-mentioned "at the time of guiding the setup" is at the time of guiding the operator to set up the production job based on the setup list. Therefore, if the setup is being guided, the present is the setup guidance time, and if the guidance is scheduled after the execution of the production job is completed, the guidance schedule time is the setup guidance time. Further, the above-mentioned "usable number of feeders 23" is the number of feeders 23 that are allowed to be set in the component supply device 20 at the time of setting up guidance. Specifically, as shown in FIG. 10, the usable number Mv1 of the feeder 23 is, for example, from the number Nw owned by the feeder 23 in the facility where the production line is installed, the number of component mounting machines 1 constituting the production line. It corresponds to the number of stocks Ns obtained by subtracting the number of used Nus set in the component supply device 20 (Mv1 = Ns = Nw-Nu).

When the operator requests that the fifth production job (JobE) be added to the setup target, the list editorial unit 72 requires the feeder 23 (Ev5) rather than the usable number Mv1 of the feeder 23. Is small (Mv1> Ev5), so edit so that up to the fifth production job (JobE) is added to the setup list as requested. On the other hand, when the operator requests that the sixth production job (JobF) be added to the setup target, the list editorial unit 72 has the required number of feeders 23 from the usable number Mv1 of the feeders 23 (the required number of feeders 23). Since Ev6) is large (Mv1 <Ev6), editing as requested is not permitted.

When the required number (Ev6) of the feeder 23 exceeds the usable number Mv1 (Mv1 <Ev6) as described above, the list editing unit 72 is requested to add a plurality of production jobs (JobD, JobE, JobF). ), The required number (Ev4, Ev5, Ev6) is calculated, and one or more production jobs are performed according to the operator's request within the range where these required numbers (Ev4, Ev5, Ev6) do not exceed the usable number Mv1. Edit to add to the setup list. That is, in the above example, the list editing unit 72 edits so that up to the fifth production job (JobE), which is the required number (Ev5) of the feeder 23 that does not exceed the usable number Mv1, is added to the setup list. do.

Further, in the above example, in order to simplify the explanation, the inventory number Ns of the feeder 23 and the usable number Mv1 are equal to each other. On the other hand, the usable number of the feeder 23 may be smaller than the stock number Ns of the feeder 23. For example, as shown in FIG. 10, the usable number Mv2 of the feeder 23 is to execute a production job in the other production line when there is another production line sharing the feeder 23 in the facility where the production line is installed. The amount (reserved number Nr) for which the feeder 23 used in the above is reserved is subtracted from the inventory number Ns and calculated (Mv2 = Ns-Nr). In this way, when a smaller number of usable numbers Mv2 than the number of stocks Ns is acquired by the reserved number Nr or the like, the required number (Ev4) of the fourth production job (JobD) exceeds the usable number Mv2. Therefore, the list editing unit 72 allows addition to the setup list up to the third production job (JobC) corresponding to the required number (Ev3) of which the usable number is Mv2 or less.

Further, the inventory number Ns of the feeder 23 may include the number of feeders 23 collected at the time of setup guidance by the collection guidance described later. As described above, the list editorial unit 72 has the required number of feeders 23 (Ev4, Ev5, Ev6, ...) According to the operator's request, and the usable numbers Mv1, Mv2 that can vary depending on the setup guidance. Based on, edit the setup list to the extent allowed by certain constraints.

Further, the usable numbers Mv1 and Mv2 may be calculated by using the maximum number of feeders 23 that can be used (reusable) for the production job instead of the possessed number Nw as described above. The maximum number of feeders 23 is set, for example, by the manager or operator of the production line. The list editorial unit 72 uses the feeder 23 used in a plurality of production jobs requested by the operator to be added to the setup target (the number used set in the component supply device 20 of the plurality of component mounting machines 1). If (including Nu) exceeds the above maximum number, edit so that the production job is added to the setup list at the request of the operator within the range where the number of uses does not exceed the maximum number. When editing is performed in a range different from the operator's request, the list editing unit 72 guides the required number of feeders 23 (Ev4, Ev5, Ev6, ...) According to the request and the setup. The usable number Mv1 (Mv2) of the feeder 23 at the time may be indicated to the operator, and the operator may be notified of the contents of the edits made within the permissible range.

In addition to the above, the "certain constraint" includes a constraint based on the situation that the setup preparation is insufficient and all the requested setups cannot be completed. Specifically, if the feeder 23 is not loaded with a reel of an appropriate part type, or if the feeder 23 is loaded with a reel and an appropriate part type is associated with the feeder 23, the preparation carriage 80 described later may be used. It is assumed that the feeder 23 is not loaded. In such a case, the list editorial unit 72 finally determines which feeder 23 should be set in which slot 21 of the component supply device 20, and completes the setup in response to the operator's request. You may try to guide as much as you can.

Here, when the target production quantity in the production plan is changed before or during the execution of the production, the host computer 60 changes the production schedule based on the changed production plan and the product data. In such a case, the list editing unit 72 edits the production jobs included in the setup list so as to increase or decrease according to the change of the production schedule. Specifically, for example, when the production of the second product type U2 is stopped, the target production number T2 of the second product type U2 is set to 0 by the host computer 60, and the second production job (JobB) is set from the production schedule. ) Is deleted.

Then, the list editorial unit 72 is the setup of the second production job (JobB) in the setup list according to the change of the production schedule, and the other production jobs (JobA, JobC) belonging to the same group (Gr01). ) Is not affected. Edit to remove the setup from the setup list. The setup to be deleted is, for example, a replenishment process of the feeder 23 loaded with the component types used only in the second production job (JobB).

The guidance unit 73 guides the operator to set up the production job based on the initial setup list generated by the host computer 60 or the setup list edited by the list editing unit 72. Specifically, the guide unit 73 guides by displaying the contents of the setup on, for example, a tablet terminal (not shown) carried by the operator. In the present embodiment, the guide unit 73 displays the contents of the setup on the display device 82 provided on the preparation carriage 80. Further, the above-mentioned "contents of setup" means any feeder 23 (Fdx10, Fdx11) in each slot 21 (SL01, SL02, ...) Of the component supply device 20 when the setup is a replenishment process of the feeder 23. , ...) is the content indicating whether to set (see Table 1 in FIG. 5).

Here, the setup of the production job includes a replenishment process of a replacement element that is replaceably set in the component mounting machine 1. Specifically, the replacement element includes a feeder 23 set in the component supply device 20, a mounting head 33 and a suction nozzle 34 mounted on a mounting table, a mounting table on which a plurality of suction nozzles 34 are mounted, and the like. is assumed. The guide unit 73 guides the supply of replacement elements based on the setup list, and when the setup list is edited or when the execution of some production jobs in the production schedule is completed, the guide unit 73 is based on the setup list. Guide the recovery of the exchange element (see Table 2 in FIG. 5).

Here, as shown in Table 3 of FIG. 4, start conditions used for determining whether or not to start execution of each production job are set for each of the plurality of production jobs included in the production schedule (for example,). , It is shown that the start condition of "JobA" is "Set1" and the start condition of "JobF" is "Set3"). When the component mounting machine 1 executes a predetermined production job, it determines whether the above start condition is satisfied, and starts the production job when the start condition is satisfied. In the present embodiment, the component mounting machine 1 is set as a start condition of a production job to be executed next time to finish the setup of one or a plurality of designated production jobs among the plurality of production jobs.

Specifically, multiple production jobs (JobA, JobB, JobC) grouped (Gr01) so that they can be executed in one setup execute group production that executes these production jobs in a series. Initially, the start condition is the end of the setup (Set1) of all the plurality of grouped production jobs. On the other hand, for a single production job (JobF) that is not grouped, the end of the setup (Set3) of the production job is a start condition. When the guide unit 73 collectively guides the setups (Set1 and Set2) of a plurality of production jobs (for example, JobA to JobE), as shown in Table 1 of FIG. 5, the production in which each setup is executed next time. Information indicating whether or not it is a job (JobA) start condition is provided together with each setup. In the column of "start condition" in Table 1 of FIG. 5, a black circle indicates that the set of the feeder 23 in the slot 21 is set to the "start condition", and "-" indicates that the above set is set to the "start condition". Indicates that it is not set.

The condition editing unit 74 accepts editing of the start condition of a predetermined production job in the production schedule, and transfers the edited start condition to the component mounting machine 1 for updating. As a result, the component mounting machine 1 determines whether or not to start executing the production job based on the edited start condition. The condition editing unit 74 accepts editing of the start condition of the production job, for example, via an input device (not shown) or a host computer 60. At this time, the condition editing unit 74 makes it possible to individually edit the start conditions for each of the production jobs (JobA, JobB, JobC) belonging to the group (Gr01).

That is, in the initial stage, since a plurality of production jobs belonging to the same group (Gr01) can be executed by one setup (Set1), the setup (Set1) is set as a start condition. However, even in the same group (Gr01), for example, the first production job (JobA) to be executed becomes a state in which the production job (JobA) can actually be executed once the setup of the production job (JobA) is completed. Therefore, the condition editing unit 74 also accepts editing of a plurality of grouped production jobs when a start condition is set for each of the plurality of production jobs.

When the start conditions of a predetermined production job (for example, JobA, JobB, JobC) are edited by the condition editing unit 74, the guide unit 73 executes each setup next time as shown in Table 3 of FIG. Information indicating whether or not the production job (JobA) is a start condition is provided together with the setup (Set1). In Table 3 of FIG. 5, a plurality of production jobs (JobA, JobB, JobC) belong to a predetermined group (Gr01), and a part of the setup required for executing the first production job (JobA) (Set1-1). Illustrates the content guided by the guide unit 73 when only the start condition is edited. According to this example, a production job (JobB, JobC) different from the first production job (JobA) belongs to the same group (Gr01) as the first production job (JobA), but the start condition of the first production job (JobA). It does not become. That is, the first production job (JobA) can be started before the setup (Set1-2, Set1-3) required for executing the above-mentioned production job (JobB, JobC) is completed.

As shown in FIG. 1, the preparation carriage 80 is configured to be movable along the transport direction of the circuit board 90 in the production line. The preparation trolley 80 loads the replacement element set in the component mounting machine 1 by the replacement process in the setup of the production job. In the present embodiment, the preparation trolley 80 is loaded with a plurality of feeders 23 used for executing a plurality of production jobs as exchange elements. As shown in FIG. 3, the preparation trolley 80 has a plurality of slots 81, a display device 82, and a reader device 83. The plurality of slots 81 are configured in the same manner as the plurality of slots 21 in the component supply device 20, and support the replacement feeder 23.

The preparation trolley 80 is configured such that a row of a plurality of slots 81 arranged in the horizontal direction is arranged in two stages in the vertical direction (not shown). Further, the replacement feeder 23 set in each of the plurality of slots 81 is electrically connected to the preparation carriage 80, is supplied with power, and can be controlled from the outside. The display device 82 displays to the operator the contents (Table 1 to Table 3 in FIG. 5) guided by the guide unit 73 of the setup support device 70. In the present embodiment, the display device 82 is configured by a touch panel and functions as an input device that accepts various operations by an operator.

Here, when the replacement feeder 23 loaded on the preparation carriage 80 is loaded with a reel of a predetermined component type, a process of associating the component type with the feeder 23 is executed in advance. As a result, feeder data (see Table 1 in FIG. 7) in which the reel ID and the component type are associated with the feeder ID, which is the unique identification information of the feeder 23, is generated. The feeder data is shared with the host computer 60 and the setup support device 70.

Then, when the replacement feeder 23 is set in the slot 81 of the preparation carriage 80, the feeder ID of the feeder 23 is read and recognized by the setup support device 70. As a result, loading information (Table 2 in FIG. 7) indicating a plurality of replacement feeders 23 loaded on the preparation trolley 80 is generated. The above loading information is obtained in the slot 81 (slot ID) of the preparation trolley 80, the replacement feeder 23 (feeder ID), the loaded reel (reel ID), and the component types (Pa, Pb, Pc, ... ) Is the associated information. The above loading information is updated every time the feeder 23 is inserted / removed from the slot 81 of the preparation carriage 80.

The reader device 83 constitutes an identification device that acquires the identification information of the component supply device 20. The reader device 83 is provided on the side surface of the preparation carriage 80 facing the front surface of the component mounting machine 1 at a height similar to that of the tag 24 of the component supply device 20, and has a communication device that wirelessly communicates with the tag 24. This communication device is configured to be able to read the identification information of the component supply device 20 by wireless communication with the tag 24.

According to such a configuration, when the preparation trolley 80 is moved along the transport direction of the circuit board 90 in the production line and the preparation trolley 80 approaches the predetermined parts supply device 20 to a predetermined distance, the tag 24 and the reader Wireless communication with the device 83 is performed. As a result, the setup support device 70 reads the identification code recorded on the tag 24 and acquires the identification information of the component supply device 20 recorded on the identification code.

(Setup guidance processing)
The guide processing for setting up the production job by the setup support device 70 will be described with reference to FIGS. 4 to 8. Here, it is assumed that the above setup is a replenishment process of the replacement element (feeder 23) that is replaceably set in the component mounting machine 1. Further, it is assumed that the preparation carriage 80 is loaded with a replacement feeder 23 used for executing a plurality of production jobs (JobA to JobG) in the production schedule.

Each of the above replacement feeders 23 is preliminarily associated with a component type corresponding to the loaded reel. The host computer 60 and the setup support device 70 have feeder data generated based on the above association (Table 1 in FIG. 7), and loading information indicating a plurality of feeders 23 loaded on the preparation carriage 80 (Table in FIG. 7). 2) is shared. As shown in FIG. 4, the above production schedule is generated based on the production plan and product data, and is stored in the storage unit 71 of the setup support device 70. The execution order of the plurality of production jobs in the production schedule is optimized in advance in the host computer 60.

Further, in the present embodiment, the mounting process in the plurality of production jobs is optimized for the purpose of shortening the time required to execute the plurality of production jobs. As a result, in order to shorten the moving distance of the mounting head 33 in the mounting process, the component types to be supplied in each of the plurality of slots 21 in the component supply device 20 are preset. In other words, the feeder 23 to which the component type is associated by loading the reel is preset in which slot 21 in the component supply device 20 is set.

Further, the host computer 60 generates the initial setup list Ls1 based on the two groups (Gr01 and Gr02) selected as the setup targets in the production schedule, and stores the initial setup list Ls1 in the storage unit 71 of the setup support device 70. do. As shown in Table 4 of FIG. 4, the setup list Ls1 includes a plurality of production jobs (JobA to JobE) belonging to two groups (Gr01, Gr02). The generated setup list Ls1 is transferred to the setup support device 70 via the network and stored in the storage unit 71.

When the operator requests the setup guidance via, for example, the display device 82, the setup support device 70 starts the setup guidance process as shown in FIG. At this time, the operator inputs to the setup support device 70 which of the plurality of component mounting machines 1 constituting the production line is to be set up for the component supply device 20 of the component mounting machine 1. As the input method, a method of selecting from the options displayed on the input device or a method of directly inputting the identification information of the component supply device 20 can be adopted.

In addition to the above, in the setup support device 70, for example, the preparation trolley 80 is moved in the transport direction of the circuit board 90 to a predetermined distance to the component supply device 20 of the predetermined component mounting machine 1 among the plurality of component mounting machines 1. When the reader device 83 of the preparation trolley 80 wirelessly communicates with the tag 24 of the component supply device 20 to acquire the identification information of the component supply device 20, the setup guidance process may be started. This makes it possible to omit the operation of inputting the identification information of the component supply device 20.

In the setup guidance process, the setup support device 70 first acquires a production state including the degree of progress of the production schedule (step 11 (hereinafter, “step” is referred to as “S”)). The setup support device 70 recognizes the production job currently being executed, the production job whose execution has been completed, and the production job scheduled to be executed in the production schedule based on the production status. Here, the setup support device 70 recognizes the first production job (JobA) at the head of the production schedule as the next production job to be executed.

Next, the guide unit 73 guides the setup of the production job based on the setup list Ls1 generated as described above (S12). Specifically, as shown in Table 4 of FIG. 4, the guide unit 73 has a case where a plurality of production jobs (JobA to JobE) for two setups (Set1 and Set2) are set in the initial setup list Ls1. In addition, based on the feeder data (Table 1 in FIG. 7) and the loading information (Table 2 in FIG. 7), the parts supply device 20 provides the feeder 23 required to enable the execution of a plurality of production jobs (JobA to JobE). The contents of the set are displayed on the display device 82 so as to be set in the specific slot 21 of the above (Table 1 in FIG. 5).

At this time, the guide unit 73 guides information indicating whether or not each setup is a start condition of the production job (JobA) to be executed next time, together with each setup. Here, the first production job (JobA) belongs to the first group (Gr01), and a setup is made so that other production jobs (JobB, JobC) belonging to the first group (Gr01) can be executed. It is a starting condition. Therefore, as shown in Table 1 of FIG. 5, the guide unit 73 also guides that the entire first setup (Set1) is a start condition.

Subsequently, the guide unit 73 guides the collection of the feeder 23, which is an exchange element, based on the setup list Ls1 (S13). Specifically, the setup support device 70 has a plurality of setup support devices 70 in the component supply device 20 when the production status acquired in S11 or the setup list Ls1 is edited and a part of the setup becomes unnecessary as described later. Identify unnecessary feeders 23 set in slot 21. Then, the guide unit 73 guides the supply of the replacement feeder 23 in S12, and guides the recovery of the feeder 23 identified as unnecessary as shown in Table 2 of FIG. The guide unit 73 omits the guidance for collecting the feeder 23 when there is no unnecessary feeder 23 or when the guide unit 73 does not affect the subsequent execution of the production job even when the feeder 23 is set in the slot 21.

The list editing unit 72 determines whether or not there is an operator's request to edit the displayed setup contents (S21). When there is a request for editing the setup list Ls1 by an operator's operation on the display device 82 (S21: Yes), the list editing unit 72 specifies a production job according to the request (S22). Here, various aspects of the operator's request can be considered. For example, an operator's request specifies a specific production job or multiple production jobs, or a group of one or more production jobs to which multiple production jobs belong, or a date and time (time) to be executed according to a production schedule. It is done by doing. Then, one or more production jobs specified by these are requested to be added to the setup target or removed from the setup target.

Here, the specification of the above date and time (time) is requested to set up one or a plurality of production jobs that can be started to be executed by the specified time among a plurality of production jobs included in the production schedule, for example. To. In this case, the list editorial unit 72 may start execution by a specified time based on the production status acquired in S11, the required time of each production job included in the production schedule, and the scheduled start date and time. Identify the production job of. The list editorial unit 72 can accept the date and time (time) specified by the time zone as in the morning or today, in addition to the hour and minute.

Subsequently, the list editorial unit 72 indicates that the required number of feeders 23 used in the plurality of production jobs requested by the operator to be added to the setup target is at the time of setup guidance (here, “current” at the time of guidance). It is determined whether or not the usable number of feeders 23 that can be used in the above is exceeded (S23). In addition, the list editing unit 72 requests to add when one or a plurality of production jobs are specified by specifying the time in S22 and when the specified production jobs are insufficient in the current setup list Ls1. I reckon. On the other hand, the list editing unit 72 considers it as a request to delete when one or a plurality of production jobs are specified by time designation in S22 and when it is excessive in the current setup list Ls1.

When the required number of feeders 23 exceeds the available number (S23: Yes), the list editorial unit 72 calculates the required number for each of the plurality of production jobs requested to be added, and the required number of feeders 23 is calculated. The addition of the plurality of production jobs specified in S22 to the setup list Ls1 from the later execution order is canceled so that the number becomes less than or equal to the usable number (S24). As a result, for example, it is possible to meet the operator's request as much as possible within a range not exceeding the usable number based on the holding number Nw and the inventory number Ns of the feeder 23.

The list editing unit 72 assigns the specified production job to the specified production job when the required number of feeders 23 is less than or equal to the usable number (S23: No) or when the production job to be added to the setup list Ls1 is adjusted in S24. Based on this, the production jobs included in the setup list Ls1 are edited so as to be increased or decreased (S25). As a result, when the processing of S23 is performed, the list editing unit 72 edits the production job so as to be added to the setup list Ls1 according to the operator's request within the range where the required number does not exceed the usable number. become.

Further, according to the above processing, specifically, when the operator requests to guide the setup of the production job to be executed today (M / D1), for example (S21: Yes). First, the list editorial unit 72 identifies a plurality of production jobs (JobA to JobF) whose scheduled start date and time are set during today (M / D1) (S22). Then, the list editorial unit 72 currently adjusts the production jobs to be added as necessary (S23), and currently includes the setups (Set1 to Set3) corresponding to the specified production jobs (JobA to JobF). Edit the setup list Ls1 of (S25). As a result, the initial setup list Ls1 becomes an edited setup list Ls2 including the above setups (Set1 to Set3), as shown in Table 5 of FIG.

If there is no request to edit the setup list (S21: No), the list editing unit 72 determines whether or not the production schedule has been changed (S31). The production schedule can be changed, for example, by adding a product type newly produced by the manager of the production line on the host computer 60, stopping the production of a predetermined product type, or changing the production order. When the production schedule is changed in the host computer 60, the changed production schedule is transferred to the setup support device 70 via the network and stored in the storage unit 71.

When the production schedule is changed (S31: Yes), the list editing unit 72 edits the production jobs included in the setup list so as to increase or decrease according to the change in the production schedule (S32). The list editorial unit 72 is designated by the execution order, group, or operator of the production job according to the product type, for example, when the production schedule is changed so as to preferentially produce the board product of a predetermined product type. Identify the production job that meets your request, based on the date and time you are working on. Then edit to add one or more specific production jobs to the setup list.

When the setup list is edited in S25 or S32, the production status is acquired again (S11), and the guide unit 73 guides the setup based on the edited setup list (S12). Specifically, for example, when the original setup list Ls1 is edited (S25) to become the setup list Ls2, the guide unit 73 uses the setup list Ls2, feeder data (Table 1 in FIG. 7), and loading information. Based on (display 2 in FIG. 7), the set contents are set so that the feeder 23 necessary for enabling a plurality of production jobs (JobA to JobF) can be set in a specific slot 21 of the component supply device 20. Is displayed on the display device 82 (Table 1 in FIG. 6). Further, the guide unit 73 also guides the collection of the feeder 23, which is an exchange element, depending on the fluctuation of the production state or the editing state of the setup list Ls2 (S13).

If there is no operator request or change in the production schedule (S31: No), the setup support device 70 determines whether or not to continue the setup guidance (S41). The setup support device 70 repeats the above processing, for example, when it is determined that the operator is working and the setup guidance is continued (S41: Yes), the production status is periodically acquired again (S11). On the other hand, in the setup support device 70, all the feeders 23 guided from the preparation trolley 80 are set in the slot 21 of the parts supply device 20, and all the feeders 23 guided for collection are loaded on the preparation trolley 80. When the dolly 80 is moved, it is determined that the setup guidance is not continued (S41: No), and the setup guidance process is terminated.

(Effect of the configuration of the embodiment)
The setup support device 70 is applied to a component mounting machine 1 that executes various production jobs for mounting electronic components on a circuit board 90 to produce a plurality of types of board products. The setup support device 70 has a production schedule that indicates the execution order of production jobs as the production order of a plurality of types of board products, and a state in which the production job can be executed by the component mounting machine 1 among the plurality of production jobs included in the production schedule. A storage unit 71 that stores a setup list indicating one or more production jobs selected as the target of setup, and a setup list in response to a request from an operator who sets up the component mounting machine 1 or a change in the production schedule. It is provided with a list editing unit 72 that edits the production jobs included in the above so as to increase or decrease, and a guide unit 73 that guides the operator to set up the production job based on the edited setup list.

According to such a configuration, the setup support device 70 edits the set application according to the request of the operator (S21 to S25). As a result, the setup support device 70 can change the contents of the setup according to the production state and the working state recognized by the operator. Further, the setup support device 70 edits the setup according to the change in the production schedule (S31, S32). As a result, the contents of the setup can be changed to reflect the changed production schedule on the production management side, and unnecessary setup can be prevented. By editing the setup list as described above (S25, S32), the efficiency of the setup can be improved. Further, for example, an unnecessary setup can be postponed for the next production job, and human resources such as an operator can be effectively utilized so as to perform a priority setup. In addition, if there is a change in the production schedule, it is possible to respond without generating the setup list again. Therefore, it is possible to prevent the production time from being extended and to prevent the operating rate of the component mounting machine 1 from being lowered.

In addition, the list editorial unit 72 responds to the operator's request when the operator requests that some production jobs included in the production schedule be added to the setup target or deleted from the setup target. Edit the setup list. The guide unit 73 guides the setup based on the edited setup list.

The setup support device 70 guides the operator to the setup based on the setup list showing the contents of the setup and the execution timing generated in advance by the optimization process or the like. However, depending on the working condition of the operator, it may not always be optimal to set up at the timing shown in the setup list. On the other hand, the setup support device 70 allows editing to increase or decrease the planned setup target (production job) according to the operator's request, and guides the setup based on the edited setup list. As a result, the working state and outlook of the operator are reflected, and as a result, the operating rate of the component mounting machine 1 can be improved, so that the time required for production can be shortened.

Further, when the list editorial unit 72 is requested to set up one or a plurality of production jobs that can be started to be executed by a specified time among a plurality of production jobs included in the production schedule, the operator Edit the setup list as requested. The guide unit 73 guides the setup based on the edited setup list.

According to such a configuration, the operator or the like can request the guidance of the setup according to the start time of the production job in consideration of his / her own schedule and prospect. As a result, the operator can not only wait for the setup guidance but also perform the previous setup in advance, for example, when there is time to spare. Therefore, it becomes possible to more effectively utilize human resources such as operators.

In addition, the setup includes a replenishment process of a replacement element that is replaceably set in the component mounting machine 1. The guide unit 73 guides the supply of replacement elements based on the setup list, and when the setup list is edited or when the execution of some production jobs in the production schedule is completed, the guide unit 73 is based on the setup list. Guide the recovery of exchange elements.

According to such a configuration, the setup support device 70 guides the supply of the replacement element, and also guides the collection of the replacement element that is no longer needed due to the editing of the setup list or the end of the production job. This encourages the recovery of the replacement element, allowing maintenance of the replacement element and preparation for diversion to others. In addition, it is possible to set another exchange element in the part where the recovered exchange element was set.

Further, the component mounting machine 1 is set as a start condition of a production job to be executed next time to finish the setup of one or a plurality of designated production jobs among the plurality of production jobs. When the guide unit 73 collectively guides the setups of a plurality of production jobs, the guide unit 73 guides the setups together with information indicating whether or not each setup is a start condition of the production job to be executed next time.

According to such a configuration, when the setup support device 70 collectively guides the setup, it also guides whether the next production job to be executed cannot be started unless each setup is done. As a result, the operator can satisfy the start condition of the production job to be executed next time by giving priority only to the setup corresponding to the start condition, for example, without having the operator edit the setup list by request. Thereby, depending on the production state, the stop time (setup time) of the component mounting machine 1 can be shortened. Further, after the setup which is the start condition is completed, the setup which is not the start condition is performed, so that the production job to be executed after that can be made executable.

Further, the setup support device 70 is communicably connected to the component mounting machine 1. The setup support device 70 further includes a condition editing unit 74 that accepts editing of the start conditions of a predetermined production job in the production schedule and transfers the edited start conditions to the component mounting machine 1 for updating.

According to such a configuration, the setup support device 70 allows editing of the start conditions of a predetermined production job after the setup list is generated. Further, the setup support device 70 transfers the edited start condition to the component mounting machine 1 for updating, and thereafter guides the start condition together. This makes it possible to set up the original plan in consideration of the production status, etc., and also to guide the setup that reflects the edited start conditions.

The setup also includes a replenishment process for the feeder 23, which is replaceably set in the component mounting machine 1 to supply electronic components. The guide unit 73 guides the supply of the feeder 23 used in the production job included in the setup.

The feeder 23 for supplying electronic parts is a replacement element that is replaced according to a change in the component type required for a production job, and has a larger number of replacements as a setup target than other replacement elements. Therefore, it is particularly useful to streamline the replacement (replenishment and recovery) of the feeder 23 in the setup.

Further, when the operator requests that one or more production jobs be added to the setup target, the list editorial unit 72 determines the required number of feeders required for setting up the plurality of production jobs after the addition. Based on the number of feeders that can be used at the time of setup guidance, it is determined whether or not the set application can be edited according to the operator's request.

According to such a configuration, the setup support device 70 sets the required number of feeders 23 and the usable number of feeders 23 at the time of setup guidance Mv1 (Mv2) when the operator requests to edit the setup list. Based on this, you can decide whether to edit the setup list. For example, if the operator requests an excessive increase in the number of setup targets, it is inappropriate to guide an unrealistic setup such as a lack of feeder 23. Therefore, the setup support device 70 can prevent the setup list from being improperly edited by the above configuration.

Further, when the required number of feeders 23 exceeds the usable number (S23: No), the list editing unit 72 calculates the required number for each of the plurality of production jobs requested to be added, and the required number is used. Edit to add one or more production jobs to the setup list according to the operator's request within the range not exceeding the possible number (S24, S25). The guide unit 73 guides the setup based on the edited setup list (S12).

According to such a configuration, when the required number of feeders 23 exceeds the usable number in the request for editing the setup list by the operator, the setup support device 70 requests the operator within a range in which the required number does not exceed the usable number. It becomes possible to respond to. This makes it possible to guide the realistic setup based on the properly edited setup list while preventing the setup list from being edited improperly.
