That is, it is the setup plan 32e of the work related to the replacement of the tape feeder 17 among the setup work. The setup plan 32e is created by the setup plan creation unit 31d each time a setup work is performed when the type of board to be produced is switched.

The setup plan 32e is configured by arranging unit work information 70, which defines work contents to be executed by the worker for each tape feeder 17 to be worked, in order of "work order" 71. Each unit work information 70 includes "work sequence" 71, "work type" 72, "feeder" 73, "current state" 74, "next production" 75, "part name" 76, "reel" 77, "part "number" 78 and "comment" 79 items are included.

In FIG. 6, "work type" 72 is information indicating the type of work performed in the setup work of the unit work information 70. In FIG. In FIG. 6, the types of work are "remove" indicating the work of removing the tape feeder 17 attached to the component supply section 16, and "attach" indicating the work of newly attaching the tape feeder 17 to the component supply section 16. is stipulated. As another work type, there is a "move" in which the tape feeder 17 is removed from the component supply unit 16 and then mounted on another address as it is. "Feeder" 73 is information indicating the feeder number specifying the tape feeder 17 to be worked on. “Current status” 74 indicates the current status of the tape feeder 17 to be worked in the setup work of the unit work information 70 .

In FIG. 6, "next production" 75 indicates the post-work state of the tape feeder 17 to be worked on in the setup work of the unit work information 70 . For example, "reuse" indicates that the carrier tape 18 is attached to the tape feeder 17 and stored in the material warehouse 9 or the like for use in subsequent production. "Storage" indicates that the carrier tape 18 is removed from the tape feeder 17 and stored separately in the material warehouse 9 or the like. Further, "maintenance" indicates that maintenance work for the tape feeder 17 is to be performed.

"Part name" 76 indicates the part name of the part D supplied from the tape feeder 17 to be worked. A "reel" 77 indicates an identification number attached to the reel R containing the carrier tape 18 mounted on the tape feeder 17 to be worked. "Number of parts" 78 indicates the number of parts that can be supplied from the tape feeder 17 to be worked (the number of parts stored in the carrier tape 18). "Comment" 79 indicates various kinds of instruction information supplementarily required in the setup work. For example, the position of the shelf of the material warehouse 9 where the tape feeder 17 and the reel R are stored, the information specifying the maintenance device 8 that performs the maintenance work, and the like are displayed.

In FIG. 6, for example, the unit work information 70 whose "work order" 71 is "1" (hereinafter simply referred to as "work order 1" etc.) is stored in the address 02 ("current state" 74) of the parts supply section 16. The attached feeder F02 (“feeder” 73) is removed (“work type” 72), and the carrier tape 18 is left attached (“next production” 75). It shows the work of moving to The unit work information 70 of the work order 2 is "new" ("current state" 74) attached with the carrier tape 18 containing the part B ("part name" 76) stored in the reel R07 ("reel" 77). feeder F07 to the address 02 (“next production” 75) of the parts supply unit 16 (“work type” 72).

The unit work information 70 of the work order 3 removes the feeder F04 attached to the address 04 of the parts supply section 16, removes the carrier tape 18 ("next production" 75), and separates the "shelf A2" of the material warehouse 9. It shows the work to be stored in The unit work information 70 of the work order 5 removes the feeder F05 attached to the address 05 of the parts supply unit 16, and for maintenance work ("next production" 75) to the maintenance work device 8 ("comment" 79). It shows the work of moving. The unit work information 70 of the work order 7 indicates that the feeder F11 attached to the address 07 of the parts supply unit 16 is removed, and the "shelf B3" of the material warehouse 9 temporarily stores the equipment elements waiting for the maintenance work for the maintenance work. It shows the work of moving to

In FIG. 6, the unit work information 70 of work order 5 and work order 6 indicates that the feeder F05 that supplies component A can be used continuously for the production of board type 2 to be produced next time. This is a preparatory work for removing the feeder F05 whose maintenance is recommended during the production of the part A for maintenance work and attaching another feeder F10 for supplying the part A instead. In other words, the setup plan generation unit 31d determines that the equipment element (feeder F05) attached to the production equipment can be used for the production of a new product (mounted substrate of board type 2), but the new product is being produced. When it is time for maintenance, a setup plan 32e (unit work information 70 of work orders 5 and 6) for replacing the relevant equipment element with another equipment element (feeder F10) is created.

In FIG. 3, a setup plan 32e created by the setup plan creation unit 31d is transferred to the component management device 7 and stored as a setup plan 42b. The setup instruction unit 41a transmits an instruction to sequentially display the setup work on the mobile terminal 11 carried by the worker based on the setup plan 42b. When the worker inputs completion of the instructed work to the touch panel 13 of the mobile terminal 11, the fact is transmitted to the member management device 7, and the next setup work is instructed by the setup instructing section 41a. The setup instructing unit 41a sequentially instructs the work to be performed by the worker in the member management area 4 and the component mounting line 5 based on the setup plan 42b.

Specifically, the setup instruction unit 41a first instructs the worker to perform the preparation work in the member management area 4 in order. For example, the work of picking up the equipment elements to be used in the next production from the shelf of the material storage 9, the work of attaching the carrier tape 18 to the tape feeder 17, the work of placing the equipment elements on a trolley (not shown) used when transporting the equipment elements, etc. instruct in order. Next, the setup instructing section 41a instructs the work of moving the carriage to the component mounting line 5 .

Next, the setup instruction unit 41a sequentially instructs the work of removing the equipment element from the production equipment, the work of placing the removed equipment element on a cart, and the work of mounting the equipment element brought on the cart to the production equipment. Next, the setup instructing section 41a instructs the work of moving the cart to the member management area 4. FIG. Next, the setup instructing unit 41a sequentially instructs the work of moving the equipment elements brought by the truck to the shelves of the component warehouse 9 and the maintenance work device 8. FIG.

For example, in the preparation work in the material management area 4, the setup instructing unit 41a performs the work of taking out the feeder F10 and the reel R10 from the material storage 9, and the feeding of the reel to the feeder F10 based on the unit work information 70 of the work order 6 shown in FIG. The work of attaching the carrier tape 18 stored in R10 and the work of placing it on the trolley are instructed. In addition, in the setup work in the component mounting line 5, the setup instruction unit 41a instructs the work of removing the feeder F05 from the address 05 of the component supply unit 16 and the work of placing it on the cart based on the unit work information 70 of the work order 5. . Next, the setup instructing section 41 a instructs the work of mounting the feeder F 10 brought by the truck to the address 05 of the component supply section 16 based on the unit work information 70 of the work sequence 6 .

Further, in the work after moving the cart to the member management area 4, the setup instruction unit 41a moves the feeder F05 carried by the cart to the maintenance work device 8 based on the unit work information 70 of the work order 5. instruct work. In this way, the setup instructing unit 41a removes the equipment element (feeder F05) that is due for maintenance from the production facility (address 05 of the parts supply unit 16) based on the setup plan 42b, and places the maintenance work (address 05 of the parts supply unit 16) It instructs the work to be transported to the maintenance work device 8). As a result, the operator who executes the setup work can execute the maintenance work without being particularly aware of it as part of the setup work.

In FIG. 3, the maintenance timing determination unit 31b determines the maintenance timing based on errors (monitoring results 32b) related to equipment elements used in the production of mounting boards in the component mounting line 5 collected by the line information collection unit 51a. The layout information changing section 31c creates changed layout information (layout information 32c) for the next time onward during the production of the mounting board, and the setup plan creating section 31d prepares the setup plan 32e for producing the next new product. Based on the setup plan 42b transferred from the plan creation device 3, the setup instructing unit 41a instructs the setup work.

In this way, the setup work is instructed based on the information on the current production work in the component mounting line 5 . Therefore, after the setup work such as the preparation work is started based on the next setup plan 42b, errors may occur frequently and there may be equipment elements whose maintenance is recommended during the next production. Therefore, when there is an equipment element that needs maintenance, and the setup instructing section 41a has instructed the setup work for the next production, the layout information changing section 31c does not change the next modified layout information. Instead, create change allocation information for the next and subsequent times.

FIG. 5C shows that when it is determined that the feeder F05 at the address 05 of the component supply unit 16 is due for maintenance after the instruction for the setup work for the next new product (the mounting board of the board type 2) is started, It shows changed placement information created by the placement information changing unit 31c. In this case, the placement information changing unit 31c does not change the placement information for the next time (board type 2) from the original placement information (FIG. 5A), and replaces the feeder F05 with the address 05 with the feeder F10 the next time (board type 3). Create change deployment information. Thereby, the arrangement plan 32e created by the plan creation device 3 and the arrangement plan 42b used by the component management device 7 can be prevented from being inconsistent.

Next, a maintenance support method (maintenance support program) that supports maintenance of multiple equipment elements attached to production equipment that produces products will be described along the flow of FIG. First, the management computer 2 determines whether or not it is time to issue a setup instruction based on the status of the component mounting line 5 (ST1: instruction determination step). If it is not time to issue a setup instruction (No in ST1), the line information collecting unit 51a (monitoring unit) monitors the state of a plurality of equipment elements attached to the production equipment of the component mounting line 5 (ST2: monitoring step). . The information acquisition unit 31a also collects the number of errors (monitoring results 32b) that have occurred in the production equipment in relation to the equipment elements from the monitoring results (production status information 52a).

Next, the maintenance timing determination unit 31b determines maintenance timings for the plurality of equipment elements based on the monitoring results 32b in the monitoring step (ST2) and the periodic maintenance timings for the equipment elements included in the member information 32d (ST3: Maintenance timing process). Next, the arrangement information changing unit 31c determines whether or not there is an equipment element whose maintenance period will be during the next or next production (whether or not there is an equipment element to be replaced) (ST4). If there is an equipment element that is subject to maintenance (Yes in ST4) and the instruction for setup work for the next production has not started (No in ST5), the arrangement information changing unit 31c changes the original arrangement information (FIG. 5A). Based on this, change placement information (FIG. 5B) for the next time onward is created (ST6: next time change placement information creating step).

In FIG. 7, when there is an equipment element whose maintenance period is present (Yes in ST4) and an instruction for setup work for the next production has started (Yes in ST5), the arrangement information changing unit 31c changes the original arrangement information ( Based on FIG. 5A), the changed placement information (FIG. 5C) for the subsequent rounds is created (ST7: step for creating changed placement information for the next round). If there is no facility element to be maintained during the maintenance period (No in ST4), after the next change placement information creating step (ST6) and after the next next change placement information creating step (ST7), the instruction determination step (ST1) is returned to, It is determined whether or not it is time for a setup instruction.

If it is time to issue a setup instruction (Yes in ST1), the setup planning unit 31d obtains the current layout information of the equipment elements attached to the production equipment and the layout information for producing a new product (layout information 22c). Then, based on the production plan 32a of the product, a setup plan 32e for the setup work for changing the equipment elements attached to the production equipment is created (ST8: setup plan creation step). In the setup plan creation step (ST8), the equipment elements attached to the production equipment can also be used for the production of new products, but if it is time for maintenance during the production of new products, the equipment elements A setup plan 32e is created to replace the other equipment elements (for example,

work orders

5 and 6 in FIG. 6).

In FIG. 7, the setup instructing unit 41a then instructs the setup work based on the setup plan 42b (the setup plan 32e transferred from the plan creation device 3) (ST9: setup instruction step). For example, in the setup instruction step (ST9), an instruction is given to remove the equipment element (feeder F05) that is due for maintenance from the production equipment and transport it to the location (maintenance work device 8) where the maintenance work is performed. When the setup instruction step (ST9) ends, the process returns to the instruction determination step (ST1) to determine whether or not it is time to instruct the setup. This makes it possible to avoid production stoppages due to maintenance and improve production efficiency.

In this way, if there is an equipment element that needs maintenance (Yes in ST4), and if the setup work for the next production has already been instructed in the setup instruction step (ST9) (Yes in ST5), In the modified layout information creating step (ST7), layout information (modified layout information) for producing the next new product is created.

As described above, the component mounting system 1 of the present embodiment has a maintenance time period that determines the maintenance timing for each of the plurality of equipment elements based on the monitoring results 32b of the states of the plurality of equipment elements attached to the production equipment. Based on the determination unit 31b, the current arrangement information of the equipment elements attached to the production equipment, the arrangement information (arrangement information 22c) for producing the new product, and the production plan 32a of the product, the production equipment and a setup plan creation unit 31d that creates a setup plan 32e for a setup work to change equipment elements attached to the equipment.

Then, the setup plan creating unit 31d decides that the equipment element attached to the production equipment can be used for production of the new product, but if it is time for maintenance during the production of the new product, the equipment element A setup plan 32e for exchanging the equipment with other equipment elements is created. This makes it possible to avoid production stoppages due to maintenance and improve production efficiency.

In the present embodiment, an internal setup work in which a worker does not prepare in advance in the component management area 4 and performs work such as replacement of a member on the component mounting line 5 is referred to as a setup work. The present disclosure can also be applied to external setup work in which a worker prepares in advance in the member management area 4 . For example, the tape feeders 17 to be used for subsequent production are arranged on a spare cart capable of holding a plurality of tape feeders 17 in parallel by the external setup work, and the components are supplied to the component mounting apparatuses M2 and M3 by the internal setup work. When the carriage attached to the section 16 is replaced with the spare carriage, the tape feeder 17, which is placed on the spare carriage in the external set-up work and is due for maintenance during the production of the new product, is replaced with another tape feeder which is not due for maintenance. 17 can also be applied to create a setup plan 32e.

Also, in the present embodiment, the terms "setup instruction (setup instruction unit)" and "setup plan" are used for explanation, but the terms are not limited to these terms. For example, setup instructions are synonymous with preparation instructions and pre-production preparation instructions. Also, the setup plan is synonymous with the preparation plan and the pre-production work plan.

INDUSTRIAL APPLICABILITY The maintenance support system, maintenance support method, and maintenance support program of the present disclosure have the effect of avoiding production stoppages due to maintenance and improving production efficiency, and are useful in the field of component mounting where components are mounted on boards. be.
