That is, at a certain work timing, there are a mounting machine that is a target of the setup work and a mounting machine that is not a target of the setup work. For this reason, the load of the setup work is different for each worker, and there is a possibility that the load of the setup work is uneven for each worker. If the load of the setup work is uneven for each worker, the setup work of the worker who is concentrated on the load may be delayed, and the production efficiency of the component mounting board may be reduced due to the delay of the setup work.

Yes. In general, the tape feeder is roughly classified into a splicing feeder and an automatic loading feeder (AF). The splicing feeder is configured so that one reel is mounted, and before the component storage tape is sent out from the reel and the component is cut out, the component storage tape is transferred to the subsequent component storage tape. In order to make the transition, the end portion of the preceding component storage tape and the leading end portion of the subsequent component storage tape are attached with a splicing tape or the like to connect them. That is, in the splicing feeder, the splicing work to be applied with the splicing tape or the like is performed before the parts storage tape from one reel is completed and the parts are cut, so that the subsequent part storage tape is wound. The reel supply timing is constrained when the delivery of the preceding component storage tape is completed until the preceding component storage tape runs out of parts.

  On the other hand, the AF is configured so that a plurality of reels can be mounted, and among the plurality of reels, a component storage tape (hereinafter referred to as “preceding component storage tape”) in which component supply is performed in advance is wound. When the delivery of the component storage tape from the preceding reel is completed, the component storage tape is automatically delivered from the subsequent reel on which the subsequent component storage tape is wound without performing the splicing operation. That is, in AF, the supply timing of a new reel can be freely compared with the splicing feeder without being constrained when the delivery of the component storage tape from the preceding reel on which the previous component storage tape is wound is completed.

And the component storage tape 243 that passes through the upper passage 2414AA is supported from the lower side. Specifically, the rear end portion of the tape running path 2414A has a shape that expands in the vertical direction from the front to the rear. The tape support member 2414 is inserted into the tape running path 2414A from the rear of the feeder main body 2411, and is detachably fixed to the feeder main body 2411. Thus, the rear end portion of the tape running passage 2414A is divided into an upper passage 2414AA and a lower passage 2414AB by the tape support member 2414.

  The first tape detection sensor 2416A and the second tape detection sensor 2416B are provided so as to face the tape travel path 2414A, and detect the presence or absence of the component storage tape 243 passing through the tape travel path 2414A. More specifically, the first tape detection sensor 2416A is provided at a position in front of the junction of the upper passage 2414AA and the lower passage 2414AB and facing the tape travel passage 2414A from below. On the other hand, the second tape detection sensor 2416B is provided at a position facing the upper passage 2414AA from above, and thereby detects the presence or absence of the component storage tape 243 in the upper passage 2414AA.

  The operation input unit 2415 is for the operator to send and reverse the component storage tape 243 as necessary.

As a result, the leading end of the preceding component storage tape 243 is supported by the tape support member 2414 in a state of being fitted to the first sprocket 2412A. Thereafter, the operator operates the operation input unit 2415, inputs an instruction to rotate the first sprocket 2412A, sends the component storage tape 243, and fits the tip of the component supply tape 243 with the second sprocket 2413A. .

  With the above preparation work completed, the AF 241 component supply operation is started. In the AF 241, the second sprocket 2413 </ b> A rotates, thereby feeding the component storage tape 243. Note that the first sprocket 2412A is configured to idle, and at this time, the component storage tape 243 can be delivered only by rotating the second sprocket 2413A.

  Next, the operator removes the tape support member 2414 from the feeder main body 2411 while the preceding component storage tape 243 is being fed from the reel 2420. When the tape support member 2414 is removed, the component storage tape 243 is displaced to the bottom surface of the tape travel path 2414A by its own weight. Thereby, the fitting of the preceding component storage tape 243 with the first sprocket 2412A is released. At this time, since the component storage tape 243 is fitted to the second sprocket 2413A, the component storage tape tape 243 continues to be sent out by the rotation of the second sprocket 2413A even if the fitting with the first sprocket 2412A is released.

  Next, in a state where the preceding component storage tape 243 is being delivered from the reel 2420, the operator attaches the tape support member 2414 to the feeder main body 2411, and removes the reel 2420 around which the preceding component storage tape 243 is wound. Move from the lower first reel holder 2419A to the upper second reel holder 2419B. Next, in a state where the preceding component storage tape 243 is being fed from the reel 2420 supported by the upper second reel holder 2419B, the operator moves the reel around which the subsequent component storage tape is wound to the lower second reel holder 2419B. Attached to one reel holder 2419A, the tip of the component storage tape is inserted into the upper passage 2414AA from the rear of the feeder body 2411. As a result, the leading end of the subsequent component storage tape is supported by the tape support member 2414 in a state of being fitted to the first sprocket 2412. In this manner, the reel around which the subsequent component storage tape is wound can be mounted in a state in which the parts of the preceding component storage tape 243 wound around the reel 2420 are not cut.

  Thereafter, the preceding component storage tape 243 is all pulled out from the reel 2420 supported by the upper second reel holder 2419B, and the rear end thereof passes through the position of the second tape detection sensor 2416B. When it is detected that there is no component, feeding of the subsequent component storage tape from the reel 2420 supported by the lower first reel holder 2419A is automatically started. Then, the operator removes the reel 2420 that has run out of parts from the upper second reel holder 2419B, and removes the reel on which the subsequent component storage tape is wound from the lower first reel holder 2419A to the upper second reel holder. Move to 2419B. At this time, the operator can replenish the AF 241 with a new reel on which the component storage tape is wound. The new reel supplied to the AF 241 is attached to the lower first reel holder 2419A by the operator. Here, the timing of the new reel component supply operation is not restricted when the reel 2420 around which the preceding component storage tape 243 is wound becomes out of components, and is specified by the operation planning system 3.

  The leading component storage tape 243 is fed from the reel 2420 supported by the upper second reel holder 2419B, and the leading end of the subsequent component storing tape wound around the reel supported by the lower first reel holder 2419A. In a state where the part is inserted into the upper passage 2414AA, it is impossible to mount a new reel. On the other hand, the preceding component storage tape 243 is all pulled out from the reel 2420 supported by the upper second reel holder 2419B, and the subsequent component storage tape is delivered from the reel supported by the lower first reel holder 2419A. Is started automatically, and the reel supported by the lower first reel holder 2419A is moved to the upper second reel holder 2419B, the new reel is mounted on the lower first reel holder 2419A. Is possible.

At this time, the worker can take out the first pallet 2454 that has run out of components from the cover body 2451 and supply a new first pallet to the tray feeder 245 during the production of the component mounting board. Similarly, even if a component held on the second tray TR2 placed on one second pallet 2455 out of the plurality of second pallets 2455 becomes out of components during the production of the component mounting board, The second pallet 2455 is moved to the table 2452, and the parts are supplied in a state of being held on the second tray TR2 on the moved second pallet 2455. At this time, the operator can take out the second pallet 2455 out of components from the cover body 2451 during the production of the component mounting board, and replenish the tray feeder 245 with a new second pallet. Further, during the production of the component mounting board, even if the component held on the third tray TR3 placed on one third pallet 2456 of the plurality of third pallets 2456 becomes out of components, The third pallet 2456 is moved to the table 2452, and the parts are supplied in a state of being held on the third tray TR3 on the moved third pallet 2456. At this time, the worker can take out the third pallet 2456 out of components from the cover body 2451 and supply a new third pallet to the tray feeder 245 during the production of the component mounting board.

  Management relating to a new pallet component replenishment operation for the tray feeder 245 is performed by the operation management system 3.

Next, a stick feeder as a component supply device will be described with reference to FIG. FIG. 6 is a diagram schematically showing the configuration of the stick feeder 246. A plurality of stick feeders 246 can be juxtaposed in the component supply unit 24. The stick feeder 246 is configured to supply the component E stored in a stick 2469 as a cylindrical component storage member while being pushed out from the stick 2469. The stick feeder 246 includes a frame main body 2461, a stick table 2462 provided at an upper portion of the frame main body 2461, a first chuck 2463 and a second chuck 2464, a component push-out mechanism 2465, a guide frame 2466, and a pair of guides. A rail 2467 and a conveyor belt 2468 are provided.

  The frame main body 2461 has a hollow box shape with an open top. The stick table 2462 is disposed inside the upper portion of the frame main body 2461. A plurality of sticks 2469 can be stacked on the stick table 2462. The first chuck 2463 can simultaneously hold the front end portion of the stick 2469 other than the lowest one of the plurality of sticks 2469 on the stick table 2462. Similarly, the second chuck 2464 can simultaneously hold the rear end portion of the stick 2469 other than the lowest one of the plurality of sticks 2469 on the stick table 2462.

  The part pushing mechanism 2465 pushes the part E forward from the lowest stick 2469 among the plurality of sticks 2469 on the stick table 2462. The guide frame 2466 is fixed to the front portion of the frame main body 2461, and a pair of guide rails 2467 are supported on the guide frame 2466. A conveyance belt 2468 is provided between the pair of guide rails 2467. The component E pushed forward by the component push-out mechanism 2465 is conveyed along the pair of guide rails 2467 by the conveyance belt 2468. As a result, the component E stored in the stick 2469 is supplied to the component supply position.

  When the lowermost stick 2469 is out of parts in accordance with the component supply operation, the first and second chucks 2463 and 2464 hold the sticks 2469 other than the lowermost one. In this state, the stick table 2462 is displaced to the support release position for releasing the support of the stick 2469, so that only the lowest stick 2469 is dropped by its own weight onto the inner bottom portion of the frame body 2461. After discarding the stick 2469, the stick table 2462 is returned to the support position of the stick 2469, and the first and second chucks 2463 and 2464 are opened, whereby the remaining stick 2469 on the stick table 2462. And the part E is supplied from the next (lowest) stick 2469.

The weighting coefficient J13 is a coefficient representing a weighting amount corresponding to the work amount for each setup work. The conversion work number information J14 is information indicating the “converted work number per work” for each setup work, and is information converted based on the weighting coefficient J13.

  For example, the conversion work number information J14 “N1” of the new reel replenishment work for the AF 241 whose work type information J11 is represented as “reel replenishment work” is “1”, and the work type information J11 is “pallet replenishment work”. Assuming that the conversion work number information J14 “N2” of the new pallet replenishment work for the tray feeder 245 represented as “2” is “2”. In this case, the number of operations is counted as “1” when one “reel supply operation” is performed, whereas the number of operations is “2” when one “pallet supply operation” is performed. Be counted. That is, two “reel supply operations” and one “pallet supply operation” are treated as the same work amount.

  As shown in FIG. 9, the worker capability information JH2 is information in which worker identification information J21, the work type information J11, the work identification information J12, and the work capability information J22 are associated with each other.

<Control action for management of setup work in work management system>
(About work management control operations)
With reference to FIG. 10 in addition to FIG. 7, the acquisition unit 354, the component supply management unit 355, and the accompanying work management unit 356 in the control unit 35 will be described. FIG. 10 is a diagram for explaining a work management control operation by the parts supply management unit 355 and the accompanying work management unit 356 of the work management system 3. FIG. 10 shows that the component mounting board of the first board type is produced in the first production period TW01, and then the board type is switched, and the component mounting board of the second board type is produced in the second production period TW02. An example is shown. Further, in FIG. 10, in the first production period TW01, two AFs 241 among a plurality of component supply devices arranged in parallel in the component supply unit 24 of each mounting machine 20 in each component mounting line 2A, 2B, 2C, An example is shown in which components are supplied from one tray feeder 245 and one stick feeder 246 to produce a component mounting board. Furthermore, in FIG. 10, in order to produce a component mounting board in the second production period TW02, three types of incidental work, adhesive replenishment work, pin preparation work, and nozzle preparation work, are performed during the first production period TW01. An example to do is shown.

  The acquisition unit 354 is a management start time TS that represents the start time of management of the parts replenishment work for each of the AF 241, the tray feeder 245, and the stick feeder 246, and the setup work including the adhesive replenishment work, the pin preparation work, and the nozzle preparation work. To get. The acquisition unit 354 may acquire the time at which the production of the component mounting board in the first production period TW01 is started as the management start time TS, and command information for instructing the management start is input via the operation unit 32. In this case, the time when the command information is input may be acquired as the management start time TS.

  The parts supply management unit 355 manages the parts supply work plan for each of the AF 241, the tray feeder 245, and the stick feeder 246. The parts supply work includes parts supply work for supplying a new reel to the AF 241, parts supply work for supplying a new pallet to the tray feeder 245, and parts for supplying a new stick to the stick feeder 246. Includes replenishment work. Hereinafter, the AF 241, the tray feeder 245, and the stick feeder 246 are collectively referred to as “component supply devices 241, 245, 246”, and the reel, pallet, and stick are collectively referred to as “component storage members”. In order to distinguish between the two AFs 241, they are referred to as “first AF 241 and second AF 241”.

  First, the component supply management unit 355 monitors the supply status of the component E in each of the component supply devices 241, 245, 246, and sets a replenishable period indicating a period in which the component supply operation can be performed. Specify every 246. In the example shown in FIG. 10, the replenishable period TWSA is specified for the first AF 241, the replenishable period TWSB is specified for the second AF 241, and the replenishable period TWSC is specified for the tray feeder 245. A replenishable period TWSD is specified for the stick feeder 246.

  The earliest time in each of the replenishable periods TWSA to TWSD (hereinafter referred to as “earliest time”) is preceded by component supply among a plurality of component storage members mounted on the component supply devices 241, 245, and 246. This is the time when the preceding component storage member to be performed is when the component runs out. When the preceding component storage member runs out of parts, a new component storage member can be supplied. In addition, at the latest time (hereinafter referred to as “latest time”) in each of the replenishable periods TWSA to TWSD, the total number of remaining parts of the plurality of parts storage members mounted on the parts supply devices 241, 245, and 246 is predetermined. This is the time when the remaining parts warning value is reached.

  Next, the component replenishment management unit 355 specifies a component replenishment target device to be a component replenishment operation target in the component supply devices 241, 245, and 246. Specifically, the parts replenishment management unit 355 recognizes an overlapping work management period in each of the replenishable periods TWSA to TWSD. In the example illustrated in FIG. 10, the parts supply management unit 355 performs a work management period as a period that overlaps the replenishable period TWSA of the first AF 241, the replenishable period TWSB of the second AF 241, and the replenishable period TWSC of the tray feeder 245. Recognizes TWD. The earliest time (earliest time) of the work management period TWD coincides with the earliest time T1 of the replenishable period TWSC of the tray feeder 245, and the latest time (latest time) of the work management period TWD can be replenished with the first AF 241. This corresponds to the latest time T2 in the period TWSA. Then, the component supply management unit 355 identifies all component supply devices that can perform component supply work within the work management period TWD as component supply target devices. In the example illustrated in FIG. 10, the component supply management unit 355 identifies the first AF 241, the second AF 241, and the tray feeder 245 as component supply target devices that can perform component supply work within the work management period TWD.

  In this manner, the component supply management unit 355 identifies all component supply devices that can perform component supply work within the work management period TWD as the component supply target devices. As a result, it is possible to perform “collective replenishment” in which component replenishment work by the operator is performed collectively for the component supply devices 241, 245, and 246 capable of replenishing the component storage member within the work management period TWD. For this reason, in each component mounting line 2A, 2B, 2C, the frequency which an operator goes to work position WP1, WP2 of each mounting machine 20 can be reduced, and the setup work load by the worker can be reduced. .

  Further, the parts supply management unit 355 specifies the supply work timing TH of the parts supply work within the same work management period TWD for the first AF 241, the second AF 241 and the tray feeder 245 specified as the parts supply target device. It is desirable that the parts supply management unit 355 specifies the earliest time T1 of the work management period TWD as the supply work timing TH within the work management period TWD. By setting the earliest time T1 that is the earliest time within the work management period TWD as the replenishment work timing TH, the worker can supply parts to the first AF 241, the second AF 241, and the tray feeder 245 with sufficient time. It can be performed.

  The accompanying work management unit 356 manages a plan of each accompanying work of the adhesive replenishment work, the pin preparation work, and the nozzle preparation work.

  First, the accompanying work management unit 356 specifies a recommended work start period for each accompanying work, based on the work time from the start to the end of the work of each accompanying work. In addition, the work time from the work start to the work end of each accompanying work is obtained in advance by experience for each accompanying work. In each accompanying work, the work start recommended period is a period in which work start is recommended. In the example shown in FIG. 10, the recommended work start period TWC1 is specified for the adhesive replenishment work, the recommended work start period TWC2 is specified for the pin preparation work, and the recommended work start is recommended for the nozzle preparation work. A period TWC3 is specified. The time interval between the recommended work start periods TWC1 to TWC3 in each accompanying work is set to a predetermined time TC. That is, the time after the elapse of the predetermined time TC from the earliest time (earliest time) TC11 of the recommended work start period TWC1 of the adhesive replenishment work becomes the latest time (latest time) TC12 of the recommended work start period TWC1. Similarly, the time after a predetermined time TC has elapsed from the earliest time TC21 of the recommended work start period TWC2 of the pin preparation work becomes the latest time TC22 of the recommended work start period TWC2. Further, the time after the predetermined time TC has elapsed from the earliest time TC31 of the recommended work start period TWC3 of the nozzle preparation work becomes the latest time TC32 of the recommended work start period TWC3.

  In addition, the accompanying work management unit 356 adds the estimated work end time TCEA that is assumed to be completed when each accompanying work is started from the latest times TC12, TC22, and TC32 of the recommended work start periods TWC1 to TWC3. Identify each task. The estimated work end time TCEA in each accompanying work is a time at which a predetermined work time has elapsed from the latest time TC12, TC22, TC32 of each work start recommended period TWC1 to TWC3. In the example shown in FIG. 10, for the adhesive replenishment work, the time when the work time WT1 has elapsed from the latest time TC12 of the work start recommendation period TWC1 is specified as the work end expected time TCEA. For the pin preparation work, the time when the work time WT2 has elapsed from the latest time TC22 of the work start recommended period TWC2 is specified as the work end expected time TCEA. For the nozzle preparation work, the time when the work time WT3 has elapsed from the latest time TC32 of the recommended work start period TWC3 is specified as the work end expected time TCEA.

  The estimated work end time TCEA of each accompanying work is set to coincide with the board type switching timing TP in the production of the component mounting board. In other words, the latest times TC12, TC22, and TC32 of the recommended work start periods TWC1 to TWC3 in each accompanying work are set so that the expected work end time TCEA coincides with the board type switching timing TP. The board type switching timing TP is a timing for dividing the first production period TW01 and the second production period TW02.

  Next, the incidental work management unit 356 includes, in each incidental work, an object to start work within the work management period TWD for all incidental work in which the work start recommendation periods TWC1 to TWC3 include the earliest time of the work management period TWD. Is identified as the starting work. In the example illustrated in FIG. 10, the incidental work management unit 356 performs adhesive replenishment work, pin preparation work, and nozzle preparation work in which work start recommendation periods TWC1 to TWC3 including the earliest time T1 of the work management period TWD are set. It is specified as a start target work for starting the work within the work management period TWD.

  As described above, the accompanying work management unit 356 specifies all accompanying works in which the earliest time T1 of the work management period TWD is included in the recommended work start periods TWC1 to TWC3 specified for each accompanying work as start target works. This start target work is an accompanying work that is a target for starting the work within the work management period TWD. That is, the accompanying work specified as the start target work can be started within the work management period TWD in the same period as the “collective supply” of the parts supply work. For this reason, it is possible to reduce the load of the setup work including the accompanying work in addition to the parts supply work by the worker.

  Further, the accompanying work management unit 356 specifies the same work start timing for the accompanying work specified as the start target work. The accompanying work management unit 356 specifies the supply work timing specified by the parts supply management unit 355 as the work start timing. In the example illustrated in FIG. 10, for the adhesive replenishment work, the pin preparation work, and the nozzle preparation work specified as the work to be started within the work management period TWD, the same timing as the replenishment work timing TH is started. It is specified as the timing TS.

(About work area setting control operation and movement route setting control operation)
Next, the work area setting control operation by the work area setting unit 358 in the control unit 35 and the movement route setting control operation by the movement route setting unit 359 will be described with reference to FIG. 12 in addition to FIG. FIG. 12 is a diagram for explaining a setting control operation by the work area setting unit 358 and the movement route setting unit 359 of the work management system 3.

  A plurality of component mounting lines 2A, 2B, and 2C are set with a work management target area AR01 that is an entire management target area of the setup work in each of the component mounting lines 2A, 2B, and 2C. This work management target area AR01 is an area including all areas in which the component mounting lines 2A, 2B, and 2C are arranged.

  In addition, the acquisition unit 354 acquires the number-of-workers information indicating the number of workers performing the setup work in the work management target area AR01. When information on the number of workers is input via the operation unit 32, the acquisition unit 354 acquires the number of workers information based on the information. FIG. 12 illustrates an example in which the acquisition unit 354 acquires the number-of-workers information representing “3” as the number of workers performing the setup work in the work management target area AR01. In FIG. 12, “3” workers are shown as a first worker OP1, a second worker OP2, and a third worker OP3.

  Each worker OP1, OP2, OP3 moves in the work management target area AR01 while pushing the cart 100, and performs setup work at the work positions WP1, WP2 of each mounting machine 20. The cart 100 contains articles (for example, reels, pallets, sticks, etc. for parts replenishment work) that are used when the setup work is performed. The cart 100 is provided with a mobile terminal device 101. The portable terminal device 101 may be carried by each worker OP1, OP2, OP3. Information generated by a work area setting unit 358, a movement route setting unit 359, and a worker guidance unit 360, which will be described later, is input to the portable terminal device 101 via the data communication unit 31, and the information is displayed. Each worker OP1, OP2, OP3 can perform setup work in the work management target area AR01 while referring to information displayed on the mobile terminal device 101.

  The work area setting unit 358 sets the work management target area AR01 based on the worker number information acquired by the acquisition unit 354 and the work number specifying information JH3 (see FIG. 11) output from the work number specifying unit 357. These are partitioned into a plurality of work areas AR11, AR12, AR13 extending along the component mounting lines 2A, 2B, 2C. Each of the work areas AR11, AR12, AR13 is an area in which the workers OP1, OP2, OP3 are in charge of the setup work.

  The work area setting unit 358 sets the number of work areas AR11, AR12, AR13 to be the same as the number of workers represented by the worker number information. In the example shown in FIG. 12, the number of work areas AR11, AR12, AR13 is also “3” corresponding to the number of workers represented by the worker number information being “3”. Hereinafter, the work area AR11 that is the area in charge of the setup work of the first worker OP1 is referred to as “first work area AR11”, and the work area AR12 that is the area in charge of the setup work of the second worker OP2 is referred to as “second work area AR11”. The work area AR13 ”will be referred to as“ work area AR12 ”, and the work area AR13 that will be the area in charge of the setup work of the third operator OP3 will be referred to as“ third work area AR13 ”.

  Furthermore, the work area setting unit 358 adjusts the ranges of the work areas AR11, AR12, and AR13 based on the work number specifying information JH3. The work area setting unit 358 adjusts the ranges of the work areas AR11, AR12, and AR13 based on the work number information J34 that represents the number of works for each work position WP1 and WP2 of each mounting machine 20 in the work number specifying information JH3. To do. Specifically, the work area setting unit 358 sets the range of each work area AR11, AR12, AR13 so that the number of work of the setup work in each work area AR11, AR12, AR13 is equal or almost equal. adjust. For example, the number of workers represented by the number-of-workers information is “3”, and the total value of the number of work for each work position WP1, WP2 of each mounting machine 20 in the work management target area AR01 is “24”. In this case, the work area setting unit 358 adjusts the ranges of the work areas AR11, AR12, and AR13 so that the number of setup work in each work area AR11, AR12, and AR13 is equal to “8”. .

  The work area setting control operation of the work area setting unit 358 will be described in more detail as follows. First, the work area setting unit 358 works in order from the −X side end to the + X side end at the −Y side first work position WP1 of each mounting machine 20 in the first component mounting line 2A. The number of operations represented by the number specifying information JH3 is added. Next, the work area setting unit 358 works in order from the + X side end to the −X side end at the + Y side second work position WP2 of each mounting machine 20 in the first component mounting line 2A. The number of operations represented by the number specifying information JH3 is added. The work area setting unit 358 adds the number of work for each work position WP1, WP2 of each mounting machine 20 in the same manner for the second component mounting line 2B and the third component mounting line 2C. The work area setting unit 358 then adds the number of works for each work position WP1, WP2 of each mounting machine 20 along each component mounting line 2A, 2B, 2C to each mounting in the work management target area AR01. The first work area AR11, the second work area AR12, and the third work area AR13 are sequentially set every time the average value obtained by dividing the total value of the work numbers for the work positions WP1 and WP2 of the machine 20 by the number of workers is reached. .

  In the example shown in FIG. 12, the range of the first work area AR11 is adjusted to a range that includes all of the first work positions WP1 on the −Y side of each mounting machine 20 in the first component mounting line 2A. All the first work positions WP1 in the first work area AR11 are set as work positions that are targets of setup work, instead of the work number represented by the work number specifying information JH3.

  The range of the second work area AR12 is the second work position WP2 on the + Y side of each mounting machine 20 in the first component mounting line 2A and the -Y side of the mounting machine 20 in the second component mounting line 2B. The range is adjusted to include all of the one work position WP1 and the second work position WP2 on the + Y side of each mounting machine 20 in the second component mounting line 2B. In the second work area AR12, at the second work position WP2 on the + Y side of each mounting machine 20 in the first component mounting line 2A, the number of works represented by the work number identification information JH3 is zero, and the setup work There is an out-of-work position WP2T that is not a target. In the second work area AR12, the number of works represented by the work number identification information JH3 is also zero at the first work position WP1 on the −Y side of each mounting machine 20 in the second component mounting line 2B. There is a non-work-target position WP1T that is not a target of the setup work. Further, in the second work area AR12, the number of works represented by the work number identification information JH3 is zero at the second work position WP2 on the + Y side of each mounting machine 20 in the second component mounting line 2B, and the setup is completed. There is a non-work target position WP2T that is not a work target. In FIG. 12, the non-work target positions WP1T and WP2T are shown as hatched portions, and so on.

  The third work area AR13 includes a first work position WP1 on the −Y side of each mounting machine 20 in the third component mounting line 2C and a second work on the + Y side of each mounting machine 20 in the third component mounting line 2C. The range is adjusted to include all of the position WP2. In the third work area AR13, the number of works represented by the work number identification information JH3 is zero at the first work position WP1 on the −Y side of each mounting machine 20 in the third component mounting line 2C, and the setup work There is an out-of-work position WP1T that is out of the target. Further, in the third work area AR13, the number of work represented by the work number identification information JH3 is also zero at the second work position WP2 on the + Y side of each mounting machine 20 in the third component mounting line 2C. There is a non-work target position WP2T that is not a work target.

  As described above, the work area setting unit 358 adjusts the ranges of the work areas AR11, AR12, and AR13 based on the work number specifying information JH3 output from the work number specifying unit 357. That is, the range of each work area AR11, AR12, AR13 is adjusted based on the number of work of setup work for each work position WP1, WP2 of each mounting machine 20. Thereby, the load of the setup work by each worker OP1, OP2, OP3 in each work area AR11, AR12, AR13 can be adjusted. For this reason, it is possible to suppress the uneven load of the setup work for each of the workers OP1, OP2, and OP3, and to equalize the work load among the workers. As a result, as a whole of the plurality of component mounting lines 2A, 2B, 2C, it is possible to improve the efficiency of the setup work by each worker OP1, OP2, OP3.

  Further, as described above, the work number specifying unit 357 sets the number of all component supply work and accompanying work that can be performed within the predetermined work management period TWD for each work position WP1, WP2 of each mounting machine 20. Is configured to identify. Based on the number of work of the set-up work including the parts replenishment work and the accompanying work specified as described above, the work area setting unit 358 makes the work numbers of the work areas AR11, AR12, AR13 equal or almost equal. In addition, the range of each work area AR11, AR12, AR13 is adjusted. The workers OP1, OP2, and OP3 are all capable of being performed within a predetermined work management period TWD at the work positions WP1 and WP2 in the work areas AR11, AR12, and AR13 whose ranges are adjusted according to the number of work. The parts replenishing work and the accompanying work can be performed collectively. Thereby, it is possible to reduce the frequency of the workers OP1, OP2, OP3 going to the work positions WP1, WP2 of each mounting machine 20, and to reduce the load of the setup work by the workers OP1, OP2, OP3. it can.

  Further, the work area setting unit 358 includes work amount information JH1 (see FIG. 8) stored in the storage unit 34 and worker capability information JH2 in addition to the work number specifying information JH3 output from the work number specifying unit 357. The range of each work area AR11, AR12, AR13 may be adjusted based on the work capability information J22 (see FIG. 9). In this case, the work area setting unit 358 includes the converted work number of the setup work represented by the converted work number information J14 of the work amount information JH1, and the workers OP1, OP2, and OP3 represented by the work capacity information J22. In consideration of work ability, the range of each work area AR11, AR12, AR13 is adjusted so that the work time in each work area AR11, AR12, AR13 is equal or almost equal. Thereby, the range of each work area AR11, AR12, AR13 is not only the number of setup work for each work position WP1, WP2 of each mounting machine 20, but also the work amount for each setup work and each worker OP1, OP2, It is adjusted based on the work capacity of OP3. For this reason, as a whole of the plurality of component mounting lines 2A, 2B, and 2C, it is possible to shorten the time required until all setup operations at the work positions WP1 and WP2 of the respective mounting machines 20 are completed.

  Further, the work area setting unit 358 generates, as information indicating the identification results of the work areas AR11, AR12, and AR13, information including an image diagram in which work areas of a plurality of workers as illustrated in FIG. 12 are also described.

<Variation of Movement Route Setting Control Operation>
In the above-described embodiment, the movement path setting unit 359 does not include the non-work target positions WP1T and WP2T in the work areas AR11, AR12, and AR13, and does not exist in the work areas AR11, AR12, and AR13. A one-stroke first path that passes through all the work positions WP1 and WP2 is set as each movement path RT1, RT2, RT3. The movement path setting unit 359 is not limited to such a configuration, and each movement path is set according to whether or not the non-work target positions WP1T and WP2T exist in the work areas AR11, AR12, and AR13. It may be configured to set. A modification of the movement route setting control operation by the movement route setting unit 359 will be described below.

(First modification of movement path setting control operation)
14 and 15 are diagrams for explaining a first modification of the movement route setting control operation by the movement route setting unit 359. FIG. 14 and 15 show the movement route setting control operation of the movement route setting unit 359 for one work area AR11 among the plurality of work areas set by the work area setting unit 358. The range of the work area AR11 includes the first and second work positions WP1 and WP2 on the −Y side and + Y side of each mounting machine 20 in the first component mounting line 2A, and each mounting machine 20 in the second component mounting line 2B. The first and second work positions WP1 and WP2 on the −Y side and the + Y side are adjusted to a range that includes them.

  As described above, each mounting machine 20 in each component mounting line 2A, 2B is a set of two units connected by a fixed first connecting conveyor 23A, and each set of these mounting machines 20 jumps between them. It is connected by a movable second connecting conveyor 23B that can be raised. The operator can pass the portion of the second connection conveyor 23B from the −Y side to the + Y side by turning the second connection conveyor 23B upward and jumping up.

  First, the movement path setting unit 359 divides the work area AR11 into a plurality of unit areas AR21 to AR32 based on the arrangement position of the second connecting conveyor 23B through which an operator can pass. Specifically, the movement path setting unit 359 sets the -Y side region of each mounting machine 20 in the first component mounting line 2A in order from the -X side end to the + X side end. Each of the two connected conveyors 23B is divided into a first unit area AR21, a second unit area AR22, and a third unit area AR23 that include two first work positions WP1. In addition, the movement path setting unit 359 moves the + Y side area of each mounting machine 20 in the first component mounting line 2A in order from the + X side end to the −X side end in the second connected conveyor 23B. Each is divided into a fourth unit region AR24, a fifth unit region AR25, and a sixth unit region AR26 that include two second work positions WP2. Similarly, the movement path setting unit 359 performs second connection on the −Y side area of each mounting machine 20 in the second component mounting line 2B in order from the −X side end to the + X side end. Each conveyor 23B is divided into a seventh unit area AR27, an eighth unit area AR28, and a ninth unit area AR29 that include two first work positions WP1. In addition, the movement path setting unit 359 moves the + Y side region of each mounting machine 20 in the second component mounting line 2B in order from the + X side end to the −X side end, in order from the second connecting conveyor 23B. Each is divided into a tenth unit area AR30, an eleventh unit area AR31, and a twelfth unit area AR32 that include two second work positions WP2.

  After partitioning the work area AR11 into the first to twelfth unit areas AR21 to AR32, the movement path setting unit 359 sequentially enters the unit areas AR21 to AR32 from the first unit area AR21 toward the twelfth unit area AR32. It is determined whether there are non-work target positions WP1T and WP2T.

  When the non-work target positions WP1T and WP2T do not exist in the unit areas AR21 to AR32, that is, when the non-work target positions WP1T and WP2T do not exist at the work positions WP1 and WP2 in the work area AR11, the movement path setting unit 359 Sets the above-described first stroke RTA in a single stroke as the movement route (see FIG. 14).

It is a straight path portion extending toward the end on the + X side. The second straight path portion RTA3 passes through all the second work positions WP2 on the + Y side of each mounting machine 20 in the first component mounting line 2A, and extends from the end on the + X side along the first component mounting line 2A. It is the straight path | route part extended toward the edge part of the side. The third straight path portion RTA5 passes through all the first work positions WP1 on the −Y side of each mounting machine 20 in the second component mounting line 2B, and extends from the −X side end along the second component mounting line 2B. It is a straight path portion extending toward the end on the + X side. The fourth straight path portion RTA7 passes through all the second work positions WP2 on the + Y side of the respective mounting machines 20 in the second component mounting line 2B, and extends from the end on the + X side along the second component mounting line 2B. It is the straight path | route part extended toward the edge part of the side. The first connection path portion RTA2 has an end on the + X side of the first straight path portion RTA1 and an end on the + X side of the second straight path portion RTA3 from the side edge on the + X side of the first component mounting line 2A. Is a path portion that is connected outside and extends from the -Y side toward the + Y side. The second connection path portion RTA4 connects the −X side end portion of the second straight path portion RTA3 and the −X side end portion of the third straight path portion RTA5, from the −Y side toward the + Y side. It is an extended path part. The third connection path portion RTA6 has an end on the + X side of the third straight path portion RTA5 and an end on the + X side of the fourth straight path portion RTA7 from the side edge on the + X side of the second component mounting line 2B. Is a path portion that is connected outside and extends from the -Y side toward the + Y side.

  On the other hand, when the non-work target positions WP1T and WP2T exist in the unit areas AR21 to AR32, that is, when the non-work target positions WP1T and WP2T exist at the work positions WP1 and WP2 in the work area AR11, the movement path setting is performed. The unit 359 sets the second route RTB as the movement route (see FIG. 15). The second route RTB is a route that passes through the respective work positions WP1 and WP2 other than the non-work target positions WP1T and WP2T and does not pass through the non-work target positions WP1T and WP2T within a range in which one-stroke writing that does not intersect is possible.

  This will be described in detail with reference to FIG. The movement path setting unit 359 determines whether or not the non-work target positions WP1T and WP2T exist in the unit areas AR21 to AR32 in order from the first unit area AR21 to the twelfth unit area AR32.

  There are no work target positions in the first unit area AR21, but there are work target non-work positions WP1T and WP2T in the second to fifth unit areas AR22 to AR25, and the sixth unit area AR26. Again, there is no non-working position. In such a case, the movement path setting unit 359 sets a first straight path portion RTB1, a first short-circuit path portion RTB2, and a second straight path portion RTB3 that are continuous in a single stroke. The first straight path portion RTB1 is a path portion that passes through each first work position WP1 in the first unit area AR21 and extends from the −X side toward the + X side. + X of the first straight path portion RTB1 so that the first short-circuit path portion RTB2 passes through the second connecting conveyor 23B without passing through the second to fifth unit areas AR22 to AR25 where the non-work target positions WP1T and WP2T exist. It is a path | route part extended toward the + Y side from the edge part of a side. The second straight path portion RTB3 is a path portion that passes through each second work position WP2 in the sixth unit area AR26 and extends from the + Y side end of the first short-circuit path portion RTB2 to the −X side.

  Next, although there are no work target positions in the seventh unit area AR27, at least one work target positions WP1T and WP2T exist in the eighth to twelfth unit areas AR28 to AR32. In such a case, it is impossible to set a one-stroke path that does not pass through the non-work target positions WP1T and WP2T existing in the eighth to twelfth unit areas AR28 to AR32. For this reason, the movement path setting unit 359 does not set the short-circuit path part that does not pass through the non-work-target positions WP1T and WP2T, and the first connection path part RTB4, which continues from the second straight path part RTB3 in a single stroke, A three straight path portion RTB5, a second connecting path portion RTB6, and a fourth straight path portion RTB7 are set. The first connection path portion RTB4 is a path portion that connects the −X side end of the second straight path portion RTB3 and the −X side end of the third straight path portion RTB5. The third straight path portion RTB5 passes through all the first work positions WP1 including the work target non-work position WP1T in the seventh to ninth unit areas AR27 to AR29 and extends from the −X side toward the + X side. It is. The second connection path portion RTB6 is a path portion that connects the + X side end of the third straight path portion RTB5 and the + X side end of the fourth straight path portion RTB7. The fourth straight path portion RTB7 passes through all the second work positions WP2 including the non-work target positions WP2T in the tenth to twelfth unit areas AR30 to AR32 and extends from the + X side toward the −X side. It is.

  As described above, the movement path setting unit 359, in the work positions WP1 and WP2 of each mounting machine 20, takes a path that does not pass through the non-work-target positions WP1T and WP2T that are not set-up work targets in the work area AR11. It is set as the movement route of the worker within. Thereby, it becomes possible to shorten the path length of a movement path | route of an operator.

(Second modification of movement path setting control operation)
FIG. 16 is a diagram for describing a second modified example of the movement route setting control operation by the movement route setting unit 359. FIG. 16 shows the movement path setting control operation of the movement path setting unit 359 for one work area AR11 among the plurality of work areas set by the work area setting unit 358. The range of the work area AR11 includes the first and second work positions WP1 and WP2 on the −Y side and + Y side of each mounting machine 20 in the first component mounting line 2A, and each mounting machine 20 in the second component mounting line 2B. The first and second work positions WP1 and WP2 on the −Y side and the + Y side are adjusted to a range that includes them.

  In the second modified example of the movement route setting control operation, the movement route setting unit 359 performs the operation on the basis of the arrangement position of the second connected conveyor 23B through which the operator can pass, as in the case of the first modified example. The area AR11 is partitioned into first to twelfth unit areas AR21 to AR32. Thereafter, the movement path setting unit 359 determines whether or not the non-work target positions WP1T and WP2T exist in each of the unit areas AR21 to AR32 in order from the first unit area AR21 to the twelfth unit area AR32. .

  When there is no work target position WP1T, WP2T in each unit area AR21-AR32, that is, when there is no work target position WP1T, WP2T at each work position WP1, WP2 in work area AR11, the movement path is set. The unit 359 sets the above-described first stroke RTA in a single stroke as the movement route (see FIG. 14).

  On the other hand, when the non-work target positions WP1T and WP2T exist in the unit areas AR21 to AR32, that is, when the non-work target positions WP1T and WP2T exist at the work positions WP1 and WP2 in the work area AR11, the movement path setting is performed. The unit 359 sets the third route RTC as the movement route (see FIG. 16). The third route RTC passes through the respective work positions WP1 and WP2 other than the non-work target positions WP1T and WP2T, and is upstream in the movement direction of the worker with a work position adjacent to the non-work target positions WP1T and WP2T as a center. This is a path including the return path portion RTC7 that does not pass through the non-work-target positions WP1T and WP2T by being turned back to the downstream side.

  This will be described in detail with reference to FIG. The movement path setting unit 359 determines whether or not the non-work target positions WP1T and WP2T exist in the unit areas AR21 to AR32 in order from the first unit area AR21 to the twelfth unit area AR32.

  There are no work target positions in the first unit area AR21, but there are work target non-work positions WP1T and WP2T in the second to fifth unit areas AR22 to AR25, and the sixth unit area AR26. Again, there is no non-working position. In such a case, the movement path setting unit 359, like the first modified example of the movement path setting control operation described above, includes the first straight path portion RTC1, the first short-circuit path portion RTC2, and the A two straight path portion RTC3 is set. The first straight path portion RTC1 is a path portion that passes through each first work position WP1 in the first unit area AR21 and extends from the −X side toward the + X side. The first short circuit path portion RTC2 passes from the + X side end of the first straight path portion RTC1 toward the + Y side so as to pass through the second connection conveyor 23B without passing through the second to fifth unit areas AR22 to AR25. It is an extended path part. The second straight path portion RTC3 is a path portion that passes through each second work position WP2 in the sixth unit area AR26 and extends from the + Y side end of the first short-circuit path portion RTC2 to the −X side.

  Next, there is no work target position in the seventh unit area AR27. However, in the eighth to tenth unit areas AR28 to AR30, the + X side in the eighth unit area AR28 and the ninth unit area AR29. There are non-work target positions WP1T and WP2T on the −X side, the + X side, and the + X side in the tenth unit area AR30, and the second work position WP2 on the −X side in the tenth unit area AR30 is not a work target. Not a position. That is, in the vicinity of the + X side end of the second component mounting line 2B, the + X side in the eighth unit region AR28, the −X side and + X side in the ninth unit region AR29, and the tenth unit region AR30. The non-work target positions WP1T and WP2T exist continuously on the + X side. A second work position WP2 other than the work target non-work position exists on the −X side of the tenth unit area AR30 serving as the continuous end point position. In such a case, the movement path setting unit 359 sets the first connection path part RTC4, the third straight path part RTC5, the second short-circuit path part RTC6, and the return path part RTC7 that are continuous from the second straight path part RTC3. .

  The first connecting path portion RTC4 is a path portion that connects the −X side end of the second straight path portion RTC3 and the −X side end of the third straight path portion RTC5. The third straight path portion RTC5 includes a first work position WP1 on the −X side and + X side in the seventh unit area AR27, and a work on the first work position WP1 and + X side on the −X side in the eighth unit area AR28. This is a path portion that passes through the non-target position WP1T and extends from the −X side toward the + X side. The second short-circuit path portion RTC6 does not pass through the non-work target positions WP1T and WP2T that are continuously present on the −X side and the + X side in the ninth unit region AR29 and the + X side in the tenth unit region AR30, respectively. It is a path portion extending from the + X side end of the third straight path portion RTC5 toward the + Y side so as to pass through the second connection conveyor 23B. The return path portion RTC7 is turned around the second work position WP2 on the −X side in the tenth unit area AR30 against the one-stroke, so that the second work on the −X side in the tenth unit area AR30. This is a path portion passing through the position WP2.

  Next, at least one non-work-target position WP2T exists in the eleventh and twelfth unit areas AR31 and AR32. In such a case, it is impossible to reach the end point position of the third route RTC without passing through the non-work target position WP2T in the eleventh and twelfth unit areas AR31, AR32. For this reason, the movement path setting unit 359 passes through all the second work positions WP2 including the non-work target positions WP2T in the eleventh and twelfth unit areas AR31 and AR32 so as to be continuous from the return path portion RTC7. A fourth straight path portion RTC8 extending from the + X side toward the -X side is set.

  As described above, the movement path setting unit 359, in the work positions WP1 and WP2 of each mounting machine 20, takes a path that does not pass through the non-work-target positions WP1T and WP2T that are not set-up work targets in the work area AR11. It is set as the movement route of the worker within. Thereby, it becomes possible to shorten the path length of a movement path | route of an operator.
