The setup support apparatus disclosed in this specification executes various production jobs for mounting electronic components on a circuit board to produce a circuit board product in a component mounting machine that enables execution of the production jobs. A setup support device for supporting setup, which is a replenishment process of a feeder that supplies parts, comprising: a production schedule indicating an execution order of a plurality of production jobs; a storage unit for storing the production job selected as the target of the setup; an editing unit that edits the production job to be set up according to the change; and based on the edited setup, which feeder is set in each slot of a component supply device of the component mounting machine, and and a guide section for guiding an operator as to which feeder is to be collected from the component supply device.

According to such a configuration, the operator can satisfy the start condition of the production job to be executed next time, for example, by preferentially performing only the setup corresponding to the start condition. As a result, the downtime (setup time) of the component mounter can be shortened depending on the production state. In addition, by performing the setup that is not the start condition after the setup that is the start condition is completed, the production job to be executed after that can be made ready for execution.
The setup support device edits the setup according to changes in the production schedule. As a result, it is possible to reflect the changed production schedule on the production management side and change the contents of the setup, thereby preventing unnecessary setup. By editing the setup as described above, it is possible to improve the efficiency of the setup. In addition, for example, unnecessary setup can be postponed for the next production job, and human resources such as operators can be effectively utilized so as to perform setup that should be prioritized. Also, if there is a change in the production schedule, it can be handled without regenerating the setup list. Therefore, it is possible to prevent an increase in production time and a decrease in the operation rate of the component mounting machine.

In the identification code, an identification code (ID) that is unique identification information of the component supply device 20 is recorded. A bar code, a two-dimensional code, or the like can be applied as the identification code. In this embodiment, the identification code is recorded in a tag 24 that wirelessly communicates with a preparation truck 80, which will be described later, and transferred to the preparation truck 80 by wireless communication. The tag 24 is provided on the front surface of the component supply device 20 at a predetermined height from the floor surface on which the component mounting machine 1 is installed.

The component transfer device 30 is configured to be movable in the X-axis direction and the Y-axis direction. The component transfer device 30 includes a head driving device 31 , a moving table 32 and a mounting head 33 . The head driving device 31 is configured to be able to move the moving table 32 in the XY-axis directions by means of a direct-acting mechanism. The mounting head 33 is used for picking up electronic components supplied by the component supply device 20 and transferring them to the circuit board 90 . The mounting head 33 is fixed to the moving table 32 by a clamp (not shown).

Moreover, the mounting head 33 has a plurality of suction nozzles 34 that are detachably provided. The mounting head 33 supports each suction nozzle 34 so as to be rotatable around the R axis parallel to the Z axis and to be vertically movable. The suction nozzle 34 is controlled in its elevation position and angle with respect to the mounting head 33 and in the state of supply of negative pressure. The suction nozzle 34 is supplied with a negative pressure to suck the electronic component supplied by the feeder 23 of the component supply device 20 . The mounting head 33 and the suction nozzle 34 described above are exchanged according to the production job or mounted on a dedicated mounting table so as to be automatically exchangeable in the setup of the production job.

The component camera 41 and the board camera 42 are digital imaging devices having imaging elements such as CCDs (Charge Coupled Devices) and CMOSs (Complementary Metal Oxide Semiconductors). The component camera 41 and the board camera 42 capture an image within the field of view of the camera based on a control signal from the control device 50 connected in a communicable manner, and send image data obtained by the imaging to the control device 50 .

The component camera 41 is fixed to the base of the component mounting machine 1 so that the optical axis faces upward in the vertical direction (Z-axis direction).

It is a process that repeats The product type, which is the type of substrate product produced by executing the production job, is determined by the type of production job that is executed.

The control device 50 also controls the position of the mounting head 33 and the operation of the suction mechanism. Specifically, in the mounting process, the control device 50 inputs information output from various sensors provided in the component mounting machine 1 and the results of recognition processing such as image processing. Then, the mounting control unit 51 sends a control signal to the component transfer device 30 based on the control program, information from various sensors, and results of various recognition processes. Thereby, 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 operational status of the production line, and controls components of the production line including the component mounting machines 1 . In addition, the host computer 60 aggregates the progress of production by the component mounting machine 1 and the like. The host computer 60 stores various data used for controlling a plurality of component mounting machines 1 constituting a production line. The host computer 60 also generates a production schedule and a setup list that are used to control the setup support device 70, which will be described later.

As shown in Table 3 of FIG. 4, the production schedule indicates the execution order of production jobs (JobA, JobB, JobC, . A production schedule is generated based on the production plan (see Table 1 in FIG. 4) and product data (see Table 2 in FIG. 4). In this embodiment, the order of execution of a plurality of production jobs (JobA, JobB, JobC, . It is set in advance by processing.

In the above optimization process, for example, when some types of electronic components are common among different product types, multiple types of production jobs corresponding to these product types are sequentially executed. set. This eliminates the need for setup between production jobs for the feeder 23 that supplies common component types. Further, if the total number of component types of electronic components required for different product types is equal to or less than the number of slots 21 of component supply device 20, feeders 23 capable of supplying different component types can be set in respective slots 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, a plurality of production jobs (JobA to JobC belonging to Gr01) can be executed with one setup (Set1) for the group (Gr01). Also, the execution order of the 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 being grouped as described above.

The above production plan, as shown in Table 1 of FIG. 4, indicates target production quantities (T1, T2, T3, . . . ) for each type of board product (U1, U2, U3, . . . ) . As shown in Table 2 of FIG. 4, the product data includes the types of electronic components (Pa, Pb, Pc, Pd, . U2, U3, . . . ). In other words, the product data indicates, for each part type, the number of parts consumed when producing one board product of a predetermined product type.

As shown in Table 4 of FIG. 4, the setup list makes the production jobs executable in the component mounting machine 1 among the plurality of production jobs (JobA, JobB, JobC, . . . ) included in the production schedule. 1 shows one or more production jobs selected for setup. For example, when multiple production jobs (JobA to JobE) are selected as setup targets, or when groups (Gr01, Gr02) corresponding to these production jobs (JobA to JobE) are selected, the setup list is displayed. , a plurality of production jobs (JobA-JobE) are shown corresponding to required setups (Set1, Set2).

(Setup support device 70)
The setup support device 70 executes various production jobs (JobA, JobB, JobC, . is applied to the component mounting machine 1 that produces The setup support device 70 is communicably connected to a plurality of component mounting machines 1 and a host computer 60 that constitute a production line. 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 truck 80, as shown in FIG.

In this embodiment, the storage section 71 , the list editing section 72 , the guide section 73 and the condition editing section 74 are incorporated in a control device provided in the preparation truck 80 . The storage unit 71 is configured by 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 guidance of setup by the setup support device 70 and the like. The storage unit 71 stores the production schedule (Table 3 in FIG. 4) generated by the host computer 60 and the setup list (Table 4 in FIG. 4) transferred from the host computer 60 .

The list editor 72 increases or decreases the number of production jobs included in the setup list (Table 4 in FIG. 4) according to requests from the operator who sets up the component mounting machine 1 or changes in the production schedule (Table 3 in FIG. 4). Edit to make The list editor 72 accepts changes to the setup list by the operator 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 on the current setup list, and a request to delete some production jobs that are included in the setup list.

Further, the operator's request may take various forms. The list editor 72 displays the current setup list and production schedule, and displays individual production jobs (JobA, JobB, JobC, . . . ), groups (Gr01, Gr02, . . . ), setups (Set1, Set2, . Set3, . . . ) may be directly specified and accepted as addition and deletion requests.

In addition, the list editing unit 72 requests that one or a plurality of production jobs that can be started 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 as requested by the operator. Specifically, the list editing unit 72, as shown in Table 3 of FIG. Based on the start date and time and the input specified time, it is determined which production job is to be set up. The list editing unit 72 edits the setup list so that the determined one or more production jobs are subject to setup.

Also, with regard to the operator's request as described above, there are cases in which editing of the setup list cannot be permitted due to certain restrictions. Here, if the setup is the replenishment process of the feeders 23, the above "certain constraint" includes, for example, the number of replaceable feeders 23 for the number of component types used in all requested production jobs. Circumstantial constraints are included that cannot complete all required setups due to an insufficient number of . Therefore, in the present embodiment, the setup support device 70 edits the setup list within the range permitted by certain restrictions among the operator's requests.

Specifically, when the operator requests that one or a plurality of production jobs be added to the setup targets, the list editing unit 72 lists the feeders 23 necessary for setting up the plurality of production jobs after the addition. Based on the required number and the usable 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 in response to the operator's request. If the setup support device 70 can edit the setup list according to the request, the setup support device 70 edits the setup list so as to add one or more production jobs to the setup list according to the request.

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

Also, the above-mentioned "at the time of setup guidance" is the time at which the operator is guided to set up a production job based on the setup list. Therefore, if the setup guidance is in progress, the setup guidance time is now. Further, the above-mentioned "usable number of feeders 23" is the number of feeders 23 allowed to be set in the component supply device 20 at the time of setup guidance. Specifically, as shown in FIG. 10, the usable number Mv1 of the feeders 23 is obtained from, for example, the number Nw of the feeders 23 owned in the facility where the production line is installed, and the number of the plurality of component mounting machines 1 constituting the production line. This corresponds to the inventory quantity Ns obtained by subtracting the used quantity Nu set in the component supply device 20 (Mv1=Ns=Nw-Nu).

If the operator requests that the fifth production job (JobE) be added to the setup targets, the list editor 72 sets the required number of feeders 23 (Ev5) rather than the usable number of feeders 23 Mv1. is small (Mv1>Ev5), editing is performed 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 to add up to the sixth production job (JobF) to the setup targets, the list editing unit 72 determines the required number of feeders 23 ( Ev6) is large (Mv1<Ev6), so editing on request is not permitted.

When the required number (Ev6) of the feeders 23 exceeds the usable number Mv1 (Mv1<Ev6) as described above, the list editing unit 72 selects a plurality of production jobs (JobD, JobE, JobF ), and perform one or more production jobs according to the operator's request within a 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 the setup list so that up to the fifth production job (JobE), which is the required number (Ev5) of the feeders 23 not exceeding the usable number Mv1, is added to the setup list. do.

Further, in the above example, the stock quantity Ns of the feeders 23 is equal to the usable quantity Mv1 for the sake of simplicity of explanation. On the other hand, the usable number of feeders 23 may be smaller than the stock number Ns of feeders 23 . For example, as shown in FIG. 10, the usable number Mv2 of the feeders 23 is, when there is another production line sharing the feeder 23 in the facility where the production line is installed, the production job execution in the other production line. The number of reserved feeders 23 (reserved number Nr) is subtracted from the inventory number Ns (Mv2=Ns−Nr). In this way, when the available quantity Mv2, which is smaller than the inventory quantity Ns, is acquired due to the reserved quantity Nr, etc., the required quantity (Ev4) of the fourth production job (JobD) exceeds the available quantity Mv2. , the list editing unit 72 permits addition to the setup list up to the third production job (JobC) corresponding to the required number (Ev3) that is equal to or less than the usable number Mv2.

In addition, the number of feeders 23 in stock Ns may include the number of feeders 23 to be collected at the time of set-up guidance by collection guidance, which will be described later. As described above, the list editing unit 72 determines the required number of feeders 23 (Ev4, Ev5, Ev6, . and edit the setup list to the extent allowed by certain constraints.

Further, the usable numbers Mv1 and Mv2 may be calculated using the maximum number of feeders 23 that can be used (reused) for production jobs instead of the holding number Nw as described above. The maximum number of feeders 23 is set by, for example, a production line manager or operator. The list editing unit 72 displays the number of feeders 23 used in a plurality of production jobs requested by the operator to be added to the setup targets (the number of used feeders 23 set in the component supply devices 20 of the component mounting machines 1). Nu) exceeds the above maximum number, edit to add production jobs to the setup list according to the operator's request within the range that 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 displays the required number of feeders 23 (Ev4, Ev5, Ev6, . The available number Mv1 (Mv2) of the time feeder 23 may be indicated to the operator, and the operator may be notified of the contents of editing performed within the allowable range.

In addition to the above, "certain restrictions" include restrictions based on circumstances in which setup preparations are insufficient and all requested setups cannot be completed. Specifically, when the feeder 23 is not loaded with reels of the appropriate component type, or when the feeder 23 is loaded with reels and the appropriate component type is associated with the feeder 23, the preparation carriage 80 described below It is assumed that the feeder 23 is not loaded. In such a case, the list editing unit 72 determines that it is not possible to guide which feeder 23 should be finally set in which slot 21 in the component supply device 20, and completes the setup in response to the operator's request. Guidance may be provided as much as possible.

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

Then, in accordance with the change in the production schedule, the list editing unit 72 sets up the second production job (JobB) in the setup list and sets up other production jobs (JobA, JobC) belonging to the same group (Gr01). ) to remove setups from the setup list. The setup to be deleted is, for example, replenishment processing of the feeder 23 loaded with the component type used only in the second production job (JobB).

The guidance section 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 section 72 . Specifically, the guidance unit 73 provides guidance by displaying the contents of setup on a tablet terminal (not shown) carried by the operator, for example. In this embodiment, the guide section 73 displays the contents of the setup on the display device 82 provided on the preparation cart 80 . Further, the above-mentioned "contents of the setup" means that when the setup is the replenishment processing of the feeders 23, which feeder 23 (Fdx10, Fdx11) is inserted into each slot 21 (SL01, SL02, . . . ) of the component supply device 20 , . . . ) is set (see Table 1 in FIG. 5).

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

Here, for each of a plurality of production jobs included in the production schedule, as shown in Table 3 of FIG. 4, start conditions used to determine whether to start execution of each production job are set (eg , the start condition for "JobA" is "Set1" and the start condition for "JobF" is "Set3"). When executing a predetermined production job, the component mounting machine 1 determines whether the start condition is satisfied, and starts the production job when the start condition is satisfied. In the present embodiment, the component mounting machine 1 sets the completion of the setup of one or a plurality of designated production jobs among a plurality of production jobs as a start condition for the next production job to be executed.

Specifically, a plurality of production jobs (JobA, JobB, and JobC) grouped (Gr01) so that they can be executed with one setup are executed in series to execute group production. , the start condition is the end of setup (Set1) for all of the grouped production jobs. On the other hand, a single ungrouped production job (JobF) is started when the setup (Set3) of the production job is finished. When guiding the setups (Set1, Set2) of a plurality of production jobs (for example, JobA to JobE) collectively, the guidance unit 73 sets the production jobs to be executed next time, as shown in Table 1 of FIG. Information indicating whether or not it is a job (JobA) start condition is guided along with each setup. In the "starting condition" column of Table 1 of FIG. 5, a black circle indicates that the set of feeder 23 to slot 21 is set to "starting condition", and a "-" indicates that the set is set to "starting condition". Indicates that it is not set.

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

That is, in the initial stage, a plurality of production jobs belonging to the same group (Gr01) can be executed with one setup (Set1), so the setup (Set1) is set as a start condition. However, even in the same group (Gr01), for example, the production job (JobA) that is executed first becomes ready for execution when 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 condition editing unit 74 edits the start conditions of the predetermined production jobs (for example, JobA, JobB, and JobC), the guidance unit 73 indicates that each setup will be executed next time as shown in Table 3 of FIG. Information indicating whether or not it is a start condition for the production job (JobA) is guided along 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 part of the setup (Set1-1) required to execute the first production job (JobA) This example illustrates the contents of guidance provided by the guidance unit 73 when the content is edited so that only is the start condition. According to this example, the production jobs (JobB, JobC) different from the first production job (JobA) belong to the same group (Gr01) as the first production job (JobA), but the start condition of the first production job (JobA) is does not become That is, the first production job (JobA) can be started before the setup (Set1-2, Set1-3) necessary for executing the production jobs (JobB, JobC) is completed.

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

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

Here, when the replacement feeders 23 loaded on the preparation cart 80 are each 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) is generated in which the feeder ID, which is unique identification information of the feeder 23, is associated with the reel ID and the component type. The feeder data is shared by host computer 60 and setup support device 70 .

Then, when the replacement feeder 23 is set in the slot 81 of the preparation cart 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 carriage 80 is generated. The above-described loading information is stored in the slot 81 (slot ID) of the preparation cart 80 as the replacement feeder 23 (feeder ID), the loaded reel (reel ID), and the part types (Pa, Pb, Pc, . . . ). ) is associated information. The loading information described above is updated each time the feeder 23 is inserted into or removed from the slot 81 of the preparation truck 80 .

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

According to such a configuration, when the preparation carriage 80 is moved along the conveying direction of the circuit board 90 in the production line and the preparation carriage 80 approaches a predetermined component supply device 20 to a predetermined distance, the tag 24 and the reader are separated from each other. Wireless communication with device 83 takes place. Thereby, 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 in the identification code.

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

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

In addition, in the present embodiment, the mounting process in multiple production jobs is optimized for the purpose of shortening the time required to execute multiple production jobs. As a result, in order to shorten the movement 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 set in advance. In other words, it is preset in which slot 21 in the component supply device 20 the feeder 23 associated with the component type is set by loading the reel.

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

For example, when an operator requests setup guidance via the display device 82, the setup support device 70 starts setup guidance processing as shown in FIG. At this time, the operator inputs to the setup support device 70 which of the 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 an input method, a method of selecting from options displayed on an input device or a method of directly inputting identification information of the component supply device 20 can be adopted.

In addition to the above, the setup support device 70 moves the preparation carriage 80 in the conveying direction of the circuit board 90 and moves the predetermined distance from the component supply device 20 of the predetermined component mounting machine 1 out of the plurality of component mounting machines 1 . When the reader device 83 of the preparation cart 80 wirelessly communicates with the tag 24 of the component supply device 20 and acquires 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 the production status including the degree of progress of the production schedule (step 11 (hereinafter, "step" is abbreviated as "S")). Based on the production status, the setup support device 70 recognizes the production jobs that are currently being executed, the production jobs that have been executed, and the production jobs that are scheduled to be executed in the production schedule. Here, the setup support device 70 recognizes the first production job (JobA) at the top of the production schedule as the production job to be executed next time.

Next, the guidance 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 guiding unit 73 displays a plurality of production jobs (JobA to JobE) for two setups (Set1, Set2) in the initial setup list Ls1. Then, based on the feeder data (Table 1 in FIG. 7) and loading information (Table 2 in FIG. 7), the feeder 23 necessary for executing a plurality of production jobs (JobA to JobE) is installed by the component supply device 20. The contents of the set are displayed on the display device 82 so as to set the specific slot 21 (Table 1 in FIG. 5).

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

Subsequently, the guiding section 73 guides collection of the feeder 23, which is a replacement element, based on the setup list Ls1 (S13). Specifically, the setup support device 70 determines the production status acquired in S11 or when the setup list Ls1 is edited as will be described later and some setups are no longer necessary. Unnecessary feeders 23 set in slots 21 are specified. Then, the guide section 73 guides the supply of the replacement feeder 23 in S12, and guides the collection of the feeder 23 identified as unnecessary as shown in Table 2 of FIG. If there is no unnecessary feeder 23 or if the feeder 23 is set in the slot 21 but does not affect the execution of subsequent production jobs, the guide unit 73 omits guidance for collecting the feeder 23 .

The list editing unit 72 determines whether or not there is an operator's request to edit the contents of the displayed setup (S21). For example, when an operator operates the display device 82 to request editing of the setup list Ls1 (S21: Yes), the list editing unit 72 specifies a production job according to the request (S22). Here, the operator's request can take various forms. For example, an operator's request may specify one or more specific production jobs, or specify one or more groups to which multiple production jobs belong, or specify the date and time (time) to be executed according to the production schedule. It is done by Then, a request is made to add one or a plurality of production jobs specified by these to the targets of setup or to delete them from the targets of setup.

Here, the above date and time (time) specification is requested, for example, to set up one or more production jobs that can be started by the specified time among the plurality of production jobs included in the production schedule. be. In this case, 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, the list editing unit 72 creates one or more jobs that can be executed by the specified time. identify production jobs. Note that the list editing unit 72 can accept specification of a time zone, such as morning or today, in addition to the hour and minute as the date and time (time).

Subsequently, the list editing unit 72 determines that the necessary number of feeders 23 used in a plurality of production jobs requested by the operator to be added to the setup targets is set at the time of setup guidance (here, the time of guidance is "current"). It is determined whether or not the usable number of feeders 23 that can be used for the current operation is exceeded (S23). If one or a plurality of production jobs are specified by specifying the time in S22 and the specified production jobs are insufficient in the current setup list Ls1, the list editing unit 72 requests addition. I reckon. On the other hand, the list editor 72 regards one or a plurality of production jobs specified by the time specification in S22 as a deletion request when there is an excess in the current setup list Ls1.

If the required number of feeders 23 exceeds the usable number (S23: Yes), the list editing unit 72 calculates the required number for each of the plurality of production jobs requested to be added, and calculates the required number of feeders 23. Addition to the setup list Ls1 is canceled starting from the production job identified in S22 whose execution order is later so that the production job is equal to or less than the usable number (S24). As a result, it is possible to meet the operator's request as much as possible within a range that does not exceed the usable number based on the number Nw of feeders 23 held and the number Ns in stock, for example.

When the required number of feeders 23 is equal to or less than the usable number of feeders (S23: No), or when the production job to be added to the setup list Ls1 is adjusted in S24, the list editing unit 72 Based on this, the setup list Ls1 is edited so as to increase or decrease the number of production jobs (S25). As a result, when the process of S23 is performed, the list editing unit 72 edits so as to add production jobs to the setup list Ls1 according to the operator's request within a range in which the required number does not exceed the usable number. become.

Further, according to the above processing, specifically, for example, when the operator requests to guide the setup of the production job to be executed today (M/D1) (S21: Yes) , the list editing unit 72 first identifies a plurality of production jobs (JobA to JobF) whose scheduled start date and time are set for today (M/D1) (S22). Then, the list editing unit 72 adjusts the production jobs to be added as necessary (S23), so that the setups (Set1 to Set3) corresponding to the identified production jobs (JobA to JobF) are included. edit the setup list Ls1 (S25). As a result, the initial setup list Ls1 becomes an edited setup list Ls2 containing 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 there has been a change in the production schedule (S31). The production schedule can be changed, for example, by the production line manager in the host computer 60 adding a new product type to be produced, stopping 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 section 71 .

If there is a change in the production schedule (S31: Yes), the list editing unit 72 edits to increase or decrease the number of production jobs included in the setup list according to the change in the production schedule (S32). For example, when the production schedule is changed so as to preferentially produce substrate products of a predetermined product type, the list editing unit 72 allows the execution order, group, and operator of production jobs to be specified according to the product type. Identifies production jobs on demand based on date and time of day, etc. Then edit to add a specific production job or jobs to the setup list.

If the setup list is edited in S25 or S32, the production status is acquired again (S11), and the guidance 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 guiding unit 73 displays the setup list Ls2, the feeder data (Table 1 in FIG. 7), and the loading information. Based on (display 2 in FIG. 7), the set contents are set so as to set the feeder 23 necessary for executing a plurality of production jobs (JobA to JobF) in a specific slot 21 of the component supply device 20. is displayed on the display device 82 (Table 1 in FIG. 6). In addition, the guidance unit 73 also guides collection of the feeder 23, which is a replacement element, depending on changes in the production state or the editing state of the setup list Ls2 (S13).

If there is neither a request from the operator nor a change in the production schedule (S31: No), the setup support device 70 determines whether or not to continue guidance for setup (S41). For example, when the operator is working and the setup support device 70 determines to continue the setup guidance (S41: Yes), the setup support device 70 periodically acquires the production status again (S11) and repeats the above processing. On the other hand, the setup support device 70 sets all the feeders 23 guided from the preparation carriage 80 to the slots 21 of the component supply device 20, loads all the feeders 23 guided for collection onto the preparation carriage 80, and performs the preparation. If the carriage 80 is moved, it is determined that the setup guidance is not to be continued (S41: No), and the setup guidance processing is terminated.

(Effects of Configuration of 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 prepares a production schedule indicating the execution order of production jobs as the production order of a plurality of types of substrate products, and a state in which the component mounting machine 1 can execute the production jobs among the plurality of production jobs included in the production schedule. a storage unit 71 for storing a setup list indicating one or more production jobs selected as targets for setup to be performed; and a guide unit 73 for guiding the operator to set up the production jobs based on the edited setup list.

According to such a configuration, the setup support device 70 edits the set app list according to the operator's request (S21-S25). As a result, the setup support device 70 can change the contents of the setup according to the production status and work status recognized by the operator. The setup support device 70 also edits the setup in accordance with changes in the production schedule (S31, S32). As a result, it is possible to reflect the changed production schedule on the production management side and change the contents of the setup, thereby preventing unnecessary setup. By editing the setup list as described above (S25, S32), setup efficiency can be improved. In addition, for example, unnecessary setup can be postponed for the next production job, and human resources such as operators can be effectively utilized so as to perform setup that should be prioritized. Also, if there is a change in the production schedule, it can be handled without regenerating the setup list. 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 editing unit 72 responds to the operator's request to add some production jobs included in the production schedule to the setup targets or to delete them from the setup targets. to edit the setup list. The guidance section 73 guides the setup based on the edited setup list.

The setup support device 70 guides the operator through the setup based on a setup list indicating the contents of the setup and the execution timing generated in advance by optimization processing or the like. However, depending on the work status 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 for increasing or decreasing the scheduled setup targets (production jobs) according to the operator's request, and guides the setup based on the edited setup list. As a result, the operator's work status and outlook can be 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.

In addition, the list editing unit 72, when a request is made to set up one or more production jobs that can be started by a specified time among the plurality of production jobs included in the production schedule, the operator Edit the setup list as requested. The guidance section 73 guides the setup based on the edited setup list.

According to such a configuration, an operator or the like can request setup guidance in accordance with the start time of a production job, taking into account his/her own schedule and outlook. This allows the operator not only to simply wait for setup guidance, but also to perform setup ahead of time, for example, when there is time to spare. Therefore, human resources such as operators can be used more effectively.

The setup also includes replenishment processing for replacement elements that are replaceably set in the component mounting machine 1 . The guidance unit 73 guides the replenishment of replacement elements based on the setup list, and when the setup list is edited or when execution of some production jobs in the production schedule is completed, based on the setup list. Guidance on the collection of replacement elements.

With such a configuration, the setup support device 70 guides the supply of replacement elements, and also guides the collection of replacement elements that are no longer needed due to editing of the setup list or termination of the production job. As a result, the collection of the replacement element is promoted, and preparations for maintenance of the replacement element and diversion to others can be performed. In addition, it becomes possible to set another exchange element in the part where the collected exchange element was set.

In the component mounting machine 1, the end of the setup of one or a plurality of designated production jobs among the plurality of production jobs is set as a start condition for the next production job to be executed. When guiding setups of a plurality of production jobs collectively, the guidance unit 73 provides information indicating whether or not each setup is a starting condition for the next production job to be executed together with each setup.

According to such a configuration, the setup support device 70, when providing guidance on setup collectively, also provides guidance on whether the production job to be executed next time cannot be started unless each setup is performed. As a result, the operator can, for example, preferentially perform only the setup corresponding to the start condition, thereby satisfying the start condition of the production job to be executed next time, without editing the setup list according to the request. As a result, the stop time (setup time) of the component mounting machine 1 can be shortened depending on the production state. In addition, by performing the setup that is not the start condition after the setup that is the start condition is completed, the production job to be executed after that can be made ready for execution.

Also, 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 start conditions for a predetermined production job in the production schedule, transfers the edited start conditions to the component mounting machine 1, and updates them.

With such a configuration, the setup support device 70 allows editing of the start conditions of a given production job after the setup list is generated. Also, the setup support device 70 transfers the edited start condition to the component mounting machine 1 to update it, and thereafter guides the start condition together. As a result, it becomes possible to set up the system in consideration of the production status and the like for the initial plan, and to guide the setup in which the edited start conditions are reflected.

The setup also includes a replenishment process for the feeder 23 that is replaceably set in the component mounting machine 1 and supplies electronic components. The guide section 73 guides the replenishment of the feeder 23 used in the production jobs included in the setup.

The feeder 23 that supplies electronic components is a replaceable element that is replaced according to changes in the types of parts required for a production job, and has a larger number of replacements than other replaceable elements as an object of setup. Therefore, it is particularly useful to streamline the exchange (replenishment and recovery) of feeders 23 in the setup.

Further, when the operator requests to add one or a plurality of production jobs to the setup targets, the list editing unit 72 displays the necessary number of feeders required for setting up the plurality of production jobs after addition, Based on the available number of feeders that can be used at the time of setup guidance, it is determined whether or not the set app list can be edited according to the operator's request.

According to such a configuration, when the operator requests editing of the setup list, the setup support device 70 sets the required number of feeders 23 and the usable number Mv1 (Mv2) of the feeders 23 at the time of setup guidance. Based on this, it is possible to decide whether or not 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 the feeder 23 running out. Therefore, the setup support device 70 can prevent the setup list from being inappropriately edited by the configuration as described above.

In addition, 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. Editing is performed to add one or a plurality of production jobs to the setup list according to the operator's request within a range not exceeding the possible number (S24, S25). Guidance unit 73 guides setup based on the edited setup list (S12).

According to such a configuration, if the required number of feeders 23 exceeds the usable number in the operator's request to edit the setup list, the setup support device 70 can set the required number to the extent that the usable number does not exceed the operator's request. It becomes possible to respond to As a result, it is possible to prevent the setup list from being inappropriately edited, and provide realistic setup guidance based on the appropriately edited setup list.
