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 delivered 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 traveling passage 2414A by its own weight. As a result, the preceding component storage tape 243 is released from the fitting with the first sprocket 2412A. At this time, since the component storage tape tape 243 is fitted with the second sprocket 2413A, even if the fitting with the first sprocket 2412A is released, the parts storage tape tape 243 continues to be delivered by the rotation of the second sprocket 2413A.

Next, with the preceding component storage tape 243 being sent out from the reel 2420, the operator attaches the tape support member 2414 to the feeder main body 2411 and winds the reel 2420 around which the preceding component storage tape 243 is wound. It is moved 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 sent from the reel 2420 supported by the second reel holder 2419B in the upper row, the operator moves the reel around which the subsequent component storage tape is wound to the lower reel. 1 Attached to the reel holder 2419A, the tip of the component storage tape is inserted into the upper passage 2414AA from the rear of the feeder main body 2411. As a result, the tip 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 way, the reel on which the subsequent parts storage tape is wound can be mounted in a state where the parts of the preceding parts storage tape 243 wound around the reel 2420 are not cut off.

After that, all the preceding component storage tapes 243 are pulled out from the reel 2420 supported by the upper second reel holder 2419B, and the trailing end passes through the position of the second tape detection sensor 2416B, and the preceding component storage tape 243. When it is detected that there is no such material, the subsequent delivery of the component storage tape from the reel 2420 supported by the first reel holder 2419A in the lower stage is automatically started. Then, the operator removes the reel 2420 out of parts from the second reel holder 2419B in the upper stage, and the reel around which the subsequent parts storage tape is wound is removed from the first reel holder 2419A in the lower stage to the second reel holder in the upper stage. Move to 2419B. At this time, the operator can replenish the AF 241 with a new reel around which the component storage tape is wound. The new reel replenished for AF241 is attached to the lower first reel holder 2419A by the operator. Here, the timing of the parts replenishment work of the new reel is not restricted when the reel 2420 on which the preceding parts storage tape 243 is wound is out of parts, and is specified by the work planning system 3.

The preceding parts storage tape 243 is sent from the reel 2420 supported by the second reel holder 2419B in the upper stage, and the tip of the subsequent parts storage tape wound around the reel supported by the first reel holder 2419A in the lower stage. A new reel cannot be mounted when the portion is inserted into the upper passage 2414AA. On the other hand, all the preceding component storage tapes 243 are pulled out from the reel 2420 supported by the second reel holder 2419B in the upper stage, and the subsequent component storage tapes are sent out from the reel supported by the first reel holder 2419A in the lower stage. Is automatically started, and when the reel supported by the lower first reel holder 2419A is moved to the upper second reel holder 2419B, the new reel can be attached to the lower first reel holder 2419A. It is possible.

Similarly, on each second pallet 2455, at least one second tray TR2 in which a plurality of parts are held is placed. The parts held in the second tray TR2 are the same type of parts for each second pallet 2455. However, the types of parts held in the second tray TR2 are different from the parts held in the first tray TR1. Further, on each third pallet 2456, at least one third tray TR3 in which a plurality of parts are held is placed. The parts held in the third tray TR3 are the same type of parts for each third pallet 2456. However, the types of parts held in the third tray TR3 are different from the parts held in each of the first tray TR1 and the second tray TR2.

Each of the first pallet 2454, the second pallet 2455, and the third pallet 2456 has a function as a component storage member on which trays TR1, TR2, and TR3 on which a plurality of components are held are placed. Each of the first pallet 2454, the second pallet 2455, and the third pallet 2456 housed in the magazine 2453 was moved to a table 2452 provided so as to project outward from the cover body 2451 during the production of the component mounting substrate. Parts are supplied while being held by trays TR1, TR2, or TR3 on the moved first pallet 2454, second pallet 2455, or third pallet 2456.

Even if the parts held in the first tray TR1 placed on the first pallet 2454 of one of the plurality of first pallets 2454 run out of parts during the production of the component mounting board, the other first pallet The pallet 2454 is moved to the table 2452, and the parts are supplied while being held in the first tray TR1 on the moved first pallet 2454. At this time, the operator can take out the first pallet 2454 out of parts 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 the parts held in the second tray TR2 mounted on the second pallet 2455 of the plurality of second pallets 2455 are out of parts during the production of the component mounting board, the other The second pallet 2455 is moved to the table 2452, and the parts are supplied while being held by the second tray TR2 on the moved second pallet 2455. At this time, the operator can take out the second pallet 2455 out of parts from the cover body 2451 and supply a new second pallet to the tray feeder 245 during the production of the component mounting board. Further, even if the parts held in the third tray TR3 mounted on the third pallet 2456 of one of the plurality of third pallets 2456 are out of parts during the production of the component mounting board, the other parts may be out of stock. The third pallet 2456 is moved to the table 2452, and the parts are supplied while being held by the third tray TR3 on the moved third pallet 2456. At this time, the operator can take out the third pallet 2456 out of parts from the cover body 2451 and supply a new third pallet to the tray feeder 245 during the production of the component mounting board.

The work management system 3 manages the parts supply work of the new pallet for the tray feeder 245.

(Stick feeder)
Next, the 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 arranged side by side in the component supply unit 24. The stick feeder 246 is configured to supply the component E stored in the stick 2469 as a cylindrical component storage member while pushing it out from the stick 2469. The stick feeder 246 includes a frame main body 2461, a stick table 2462, a first chuck 2464 and a second chuck 2464 provided on the upper portion of the frame main body 2461, a component extrusion mechanism portion 2465, a guide frame 2466, and a pair of guides. A rail 2467 and a transport belt 2468 are provided.

The frame body 2461 has a hollow box shape with an open top. The stick table 2462 is arranged inside the upper part of the frame main body 2461. A plurality of sticks 2469 can be placed on the stick table 2462 in a laminated state. The first chuck 2464 can simultaneously hold the front end portion of the stick 2469 other than the lowest 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 of the plurality of sticks 2469 on the stick table 2462.

The component extrusion mechanism unit 2465 extrudes the component E in front of 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 body 2461, and a pair of guide rails 2467 are supported by the guide frame 2466. A transport belt 2468 is provided between the pair of guide rails 2467. The component E extruded forward by the component extruding mechanism portion 2465 is conveyed by the transport belt 2468 along the pair of guide rails 2467. As a result, the component E housed in the stick 2469 is supplied to the component supply position.

When the lowest stick 2469 runs out of parts due to the component supply operation, the first and second chucks 2464 and 2464 hold the sticks 2469 other than the lowest stick. In this state, the stick table 2462 is displaced to the support release position where the support of the stick 2469 is released, so that only the lowermost stick 2469 is dropped to the inner bottom portion of the frame body 2461 by its own weight. After discarding the stick 2469 that is out of parts, the stick table 2462 returns to the support position of the stick 2469, and the first and second chucks 2464 and 2464 are opened, so that the remaining sticks 2469 are placed on the stick table 2462. Is placed, and the component E is supplied from the next (lowest) stick 2469.

During the production of the component mounting board, when the out-of-component stick 2469 falls to the inner bottom of the frame body 2461, the operator can replenish the stick feeder 246 with a new stick.

The work management system 3 manages the parts replenishment work of the new stick for the stick feeder 246.

In the present embodiment, the mounting machine 20 is set with a first working position WP1 located on the −Y side of the mounting machine 20 and a second working position WP2 located on the + Y side of the mounting machine 20. The first work position WP1 is a parts supply work for a parts supply device juxtaposed with a parts supply unit 24 arranged on the −Y side in the mounting machine 20, a pin preparation work using a backup pin preparation device 29A, and a nozzle. This is a work position where setup work including nozzle preparation work using the preparation device 29B and adhesive replenishment work for the coating device 29C is performed. The second work position WP2 is a work position where parts supply work is performed for the parts supply device juxtaposed with the parts supply unit 24 arranged on the + Y side in the mounting machine 20.

FIG. 7 is a block diagram showing the configuration of the work management system 3. As shown in FIG. 1, the work management system 3 is connected to the mounting machine operation management device 4 so as to be capable of data communication. Further, the work management system 3 includes, for example, a microcomputer, and as shown in FIG. 7, includes a data communication unit 31, an operation unit 32, a display unit 33, a storage unit 34, and a control unit 35.

The operation unit 32 includes a touch panel, a numeric keypad, a start key, a setting key, and the like, and receives an operator's operation and various settings for the work management system 3. The display unit 33 displays information set by the work area setting unit 358 and the movement route setting unit 359 of the control unit 35, which will be described later, information generated by the worker guidance unit 360, and the like. The data communication unit 31 is an interface circuit for realizing data communication with an external device including the mounting machine operation management device 4. The data communication unit 31 acquires information transmitted from the mounting machine operation management device 4, and gives the acquired information to the control unit 35. Further, in the data communication unit 31, information generated by the work area setting unit 358, the movement route setting unit 359, and the worker guidance unit 360 is given from the control unit 35, and the information is given to an external device such as the mounting machine operation management device 4.

The storage unit 34 stores work amount information and worker ability information. FIG. 8 is a diagram for explaining the work amount information JH1, and FIG. 9 is a diagram for explaining the worker ability information JH2.

The work amount information JH1 is information to which a weighting coefficient according to the work amount is added to the setup work, and is information representing the work amount for each setup work. Specifically, as shown in FIG. 8, the work amount information JH1 is information in which the work type information J11, the work identification information J12, the weighting coefficient J13, and the converted work number information J14 are associated with each other. The work type information J11 is information representing the "work type" of the setup work. The work identification information J12 is information representing a "work ID" for identifying the setup work. The weighting coefficient J13 is a coefficient representing a weighting amount according to the work amount for each setup work. The conversion work number information J14 is information representing "the number of conversion work 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" for the new reel replenishment work for AF241 whose work type information J11 is represented as "reel replenishment work" is "1", and the work type information J11 is "pallet replenishment work". It is assumed 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 replenishment work" is performed, whereas the number of operations is "2" when one "pallet replenishment work" is performed. It is counted. That is, two "reel replenishment work" and one "pallet replenishment work" are treated as the same amount of work.

As shown in FIG. 9, the worker ability information JH2 is information in which the worker identification information J21, the work type information J11, the work identification information J12, and the work ability information J22 are associated with each other. The worker identification information J21 is information representing a "worker ID" for identifying a worker. The work ability information J22 is information representing the "work ability" for each setup work of the worker.

The control unit 35 of the work management system 3 is composed of a CPU (Central Processing Unit), a ROM (Read Only Memory) for storing a control program, a RAM (Random Access Memory) used as a work area of the CPU, and the like. The control unit 35 controls the data communication unit 31, the operation unit 32, the display unit 33, and the storage unit 34 by executing the control program stored in the ROM by the CPU, and generates various information related to the management of the setup work. .. As shown in FIG. 7, the control unit 35 includes a communication control unit 351, an operation control unit 352, a display control unit 353, an acquisition unit 354, a parts supply management unit 355, an incidental work management unit 356, and work.

<Control operation related to management of setup work in the work management system>
(About work management control operation)
In addition to FIG. 7, the acquisition unit 354, the parts supply management unit 355, and the incidental work management unit 356 in the control unit 35 will be described with reference to FIG. FIG. 10 is a diagram for explaining the work management control operation by the parts supply management unit 355 and the incidental work management unit 356 of the work management system 3. In FIG. 10, in the first production period TW01, the component mounting substrate of the first substrate type is produced, then the substrate type is switched, and in the second production period TW02, the component mounting substrate of the second substrate type is produced. An example is shown. Further, in FIG. 10, in the first production period TW01, two AF241 among the plurality of component supply devices arranged side by side 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 parts are supplied from one tray feeder 245 and one stick feeder 246 to produce a component mounting board. Further, in FIG. 10, in order to produce the component mounting substrate in the second production period TW02, three types of incidental work of 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 manages the management start time TS indicating the start time of the parts replenishment work for each of the AF241, the tray feeder 245, and the stick feeder 246, and the management of 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 starts as the management start time TS, or the command information for instructing the start of management is input via the operation unit 32. If so, 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 AF241, the tray feeder 245, and the stick feeder 246. Parts replenishment work includes parts replenishment work to replenish new reels to AF241, parts replenishment work to replenish new pallets to tray feeder 245, and parts to replenish new sticks to stick feeder 246. Replenishment work is included. In the following, when the AF241, the tray feeder 245 and the stick feeder 246 are collectively referred to as "parts supply device 241, 245, 246", and when the reel, pallet and stick are collectively referred to, they are referred to as "parts storage member". Further, when distinguishing between the two AF241 units, they are referred to as "first AF241 and second AF241".

First, the parts supply management unit 355 monitors the supply status of the parts E in each of the parts supply devices 241, 245, 246, and sets the supply possible period indicating the period during which the parts supply work is possible. Specify every 246. In the example shown in FIG. 10, the replenishable period TWSA is specified for the first AF241, the replenishable period TWSB is specified for the second AF241, and the replenishable period TWSC is specified for the tray feeder 245. A replenishable period TWSD has been specified for the stick feeder 246.

The earliest time (hereinafter referred to as "earliest time") in each of the replenishable period TWSA to TWSD is preceded by the parts supply among the plurality of parts storage members mounted on the parts supply devices 241, 245, 246. It is the time when the preceding parts storage member to be performed is out of parts. When the preceding parts storage member runs out of parts, it becomes possible to replenish new parts storage members. Further, the latest time (hereinafter referred to as "latest time") in each of the replenishable periods TWSA to TWSD is determined by the total number of remaining parts of the plurality of parts storage members mounted on the parts supply devices 241, 245, 246. It is the time when the warning value for the remaining number of parts is reached.

Next, the parts supply management unit 355 specifies the parts supply target device to be the target of the parts supply work in the parts supply devices 241, 245, 246. Specifically, the parts supply management unit 355 recognizes overlapping work management periods in each of the supplyable periods TWSA to TWSD. In the example shown in FIG. 10, the parts supply management unit 355 has a work management period as a period in which the replenishable period TWSA of the first AF241, the replenishable period TWSB of the second AF241, and the replenishable period TWSC of the tray feeder 245 overlap. It recognizes the TWD. The earliest time (earliest time) of the work management period TWD coincides with the earliest time T1 of the tray feeder 245 replenishable period TWSC, and the latest time (latest time) of the work management period TWD is replenishment of the first AF241. It coincides with the latest time T2 in the period TWSA. Then, the parts supply management unit 355 specifies all the parts supply devices capable of the parts supply work within the work management period TWD as the parts supply target devices. In the example shown in FIG. 10, the parts supply management unit 355 identifies the first AF241, the second AF241, and the tray feeder 245 as parts supply target devices capable of performing parts supply work within the work management period TWD.

As described above, the parts supply management unit 355 specifies all the parts supply devices capable of the parts supply work within the work management period TWD as the parts supply target devices. As a result, for the parts supply devices 241, 245, 246 that can replenish the parts storage members within the work management period TWD, it is possible to perform "collective replenishment" in which the parts replenishment work by the operator is collectively performed. Therefore, in each component mounting line 2A, 2B, 2C, the frequency with which the worker goes to the work positions WP1 and WP2 of each mounting machine 20 can be reduced, and the load of the setup work 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 work management period TWD, which is the same for the first AF241, the second AF241, and the tray feeder 245 specified as the parts supply target device. It is desirable that the parts supply management unit 355 specify 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 which is the earliest time in the work management period TWD as the replenishment work timing TH, the worker can replenish the parts for the first AF241, the second AF241, and the tray feeder 245 in a state where there is time to spare. It can be performed.

The incidental work management unit 356 manages the plans for the incidental work of each of the adhesive replenishment work, the pin preparation work, and the nozzle preparation work.

First, the incidental work management unit 356 specifies a work start recommended period for each incidental work based on the work time from the start of the work to the end of the work of each incidental work. The work time from the start to the end of each incidental work is empirically determined in advance for each incidental work. In each incidental work, the work start recommended period is the period for which the work start is recommended. In the example shown in FIG. 10, the work start recommended period TWC1 is specified for the adhesive replenishment work, the work start recommended period TWC2 is specified for the pin preparation work, and the work start recommended period is specified for the nozzle preparation work. The period TWC3 has been identified. The work start recommended period TWC1 to TWC3 in each incidental work is set to a fixed predetermined time TC. That is, the time after the lapse of a predetermined time TC from the earliest time (earliest time) TC11 of the recommended work start period TWC1 for the adhesive replenishment work is the latest time (latest time) TC12 of the recommended work start period TWC1. Similarly, the time after the lapse of a predetermined time TC from the earliest time TC21 of the recommended work start period TWC2 for the pin preparation work is the latest time TC22 of the recommended work start period TWC2. Further, the time after the lapse of a predetermined time TC from the earliest time TC31 of the recommended work start period TWC3 of the nozzle preparation work is the latest time TC32 of the recommended work start period TWC3.

Further, the incidental work management unit 356 accompanies the estimated work end time TCEA, which is assumed to be completed when each incidental work is started from the latest time TC12, TC22, TC32 of the recommended work start period TWC1 to TWC3. Specify for each work. The estimated work end time TCEA in each incidental work is the time when 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 recommended period TWC1 is specified as the work end estimated time TCEA. Further, for the pin preparation work, the time at which the work time WT2 has elapsed from the latest time TC22 of the work start recommended period TWC2 is specified as the work end estimated time TCEA. Further, for the nozzle preparation work, the time when the work time WT3 has elapsed from the latest time TC32 of the work start recommended period TWC3 is specified as the work end estimated time TCEA.

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

Next, in the incidental work management unit 356, in each incidental work, all incidental work including the earliest time of the work management period TWD in the work start recommended periods TWC1 to TWC3 is to be started in the work management period TWD. Specify as the work to be started. In the example shown in FIG. 10, the incidental work management unit 356 performs the adhesive replenishment work, the pin preparation work, and the nozzle preparation work in which the work start recommended period TWC1 to TWC3 including the earliest time T1 of the work management period TWD is set. Work management period Specify as the work to be started to start the work in the TWD.

As described above, the incidental work management unit 356 specifies all incidental work in which the work start recommended period TWC1 to TWC3 specified for each incidental work includes the earliest time T1 of the work management period TWD as the work to be started. This start target work is ancillary work that is a target for starting work within the work management period TWD. That is, the incidental work specified as the work to be started can start the work within the work management period TWD of the same period as the "collective supply" of the parts supply work. Therefore, it is possible to reduce the load of the setup work including the accompanying work in addition to the parts replenishment work by the worker.

Further, the incidental work management unit 356 specifies the same work start timing for the incidental work specified as the work to be started. The incidental 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 shown 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 work starts at the same timing as the replenishment work timing TH. It is specified as a timing TS.

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

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

It will be described in detail with reference to FIG. The movement route setting unit 359 determines in order from the first unit area AR21 toward the twelfth unit area AR32 whether or not the non-working position WP1T and WP2T exist in the respective unit areas AR21 to AR32.

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

Next, although there is no non-working position in the 7th unit area AR27, at least one non-working position WP1T and WP2T exists in the 8th to 12th unit areas AR28 to AR32. In such a case, it is impossible to set a one-stroke route that does not pass through the non-working positions WP1T and WP2T existing in the 8th to 12th unit areas AR28 to AR32. Therefore, the movement route setting unit 359 does not set the short-circuit path portion that does not pass through the work target non-working positions WP1T and WP2T, and the first connected path portion RTB4 and the first connected path portion RTB4 that are continuous from the second linear path portion RTB3 in a single stroke. 3 The straight path portion RTB5, the second connected path portion RTB6, and the fourth straight path portion RTB7 are set. The first connecting path portion RTB4 is a path portion connecting the end portion of the second linear path portion RTB3 on the −X side and the end portion of the third linear path portion RTB5 on the −X side. The third straight line path portion RTB5 passes through all the first working positions WP1 including the work target non-working position WP1T in the seventh to ninth unit regions AR27 to AR29, and the path portion extending from the −X side toward the + X side. Is. The second connected path portion RTB6 is a path portion that connects the + X side end portion of the third linear path portion RTB5 and the + X side end portion of the fourth straight line path portion RTB7. The fourth straight line path portion RTB7 passes through all the second working positions WP2 including the work target non-working position WP2T in the tenth to twelfth unit regions AR30 to AR32, and the path portion extending from the + X side toward the −X side. Is.

In this way, the movement route setting unit 359 sets the work area AR11 on a route that does not pass through the work target positions WP1T and WP2T that are not the target of the setup work in the work positions WP1 and WP2 of each mounting machine 20 to the extent possible. Set as the movement route of the worker within. This makes it possible to shorten the path length of the worker's movement path.

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

In the second modification of the movement route setting control operation, the movement route setting unit 359 works with reference to the arrangement position of the second connecting conveyor 23B through which the operator can pass, as in the case of the first modification described above. The area AR11 is divided into the first to twelfth unit areas AR21 to AR32. After that, the movement route setting unit 359 determines whether or not the non-work target positions WP1T and WP2T exist in the respective unit areas AR21 to AR32 in order from the first unit area AR21 toward the twelfth unit area AR32. ..

When the non-working positions WP1T and WP2T do not exist in the unit areas AR21 to AR32, that is, when the non-working positions WP1T and WP2T do not exist in the working positions WP1 and WP2 in the working area AR11, the movement route is set. The unit 359 sets the above-mentioned one-stroke first path RTA as a movement path (see FIG. 14).

On the other hand, when the non-work target positions WP1T and WP2T exist in each unit area AR21 to AR32, that is, when the non-work target positions WP1T and WP2T exist in each work position WP1 and WP2 in the work area AR11, the movement route is set. The unit 359 sets the third path RTC as a movement path (see FIG. 16). The third path RTC passes through the work positions WP1 and WP2 other than the work target positions WP1T and WP2T, and is on the upstream side in the moving direction of the worker centering on the work position adjacent to the work target positions WP1T and WP2T. It is a route including the return route portion RTC7 that does not pass through the non-work target positions WP1T and WP2T by turning back from the to the downstream side.

It will be described in detail with reference to FIG. The movement route setting unit 359 determines in order from the first unit area AR21 toward the twelfth unit area AR32 whether or not the non-working position WP1T and WP2T exist in the respective unit areas AR21 to AR32.

There are no non-working positions in the first unit area AR21, but non-working positions WP1T and WP2T exist in the second to fifth unit areas AR22 to AR25, and they are in the sixth unit area AR26. There is no work target position again. In such a case, the movement route setting unit 359 has the first linear path portion RTC1, the first short-circuit path portion RTC2, and the first short-circuit path portion RTC2, which are continuous in a single stroke, as in the first modification of the movement route setting control operation described above. 2 Set the straight path portion RTC3. The first straight line path portion RTC1 is a path portion extending from the −X side toward the + X side through each first working position WP1 in the first unit region AR21. 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 connecting conveyor 23B without passing through the second to fifth unit regions AR22 to AR25. It is a part of the route that extends. The second linear path portion RTC3 is a path portion that passes through each second working position WP2 in the sixth unit region AR26 and extends from the + Y side end portion of the first short-circuit path portion RTC2 to the −X side.

Next, although there is no non-working position in the 7th unit area AR27, in the 8th to 10th unit areas AR28 to AR30, the + X side in the 8th unit area AR28 and the 9th unit area AR29. The non-working position WP1T and WP2T exist on the −X side and the + X side, and the + X side in the 10th unit area AR30, and the second working position WP2 on the −X side in the 10th unit area AR30 is not the 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 8th unit area AR28, the −X side and the + X side in the 9th unit area AR29, and the 10th unit area AR30. The non-working position WP1T and WP2T exist continuously on the + X side, respectively. Then, a second working position WP2 other than the work target non-working position exists on the −X side of the tenth unit region AR30, which is the continuous end point position. In such a case, the movement route setting unit 359 sets the first connected path portion RTC4, the third straight path portion RTC5, the second short-circuited path portion RTC6, and the folded path portion RTC7 that are continuous from the second straight path portion RTC3. ..

The first connected path portion RTC4 is a path portion that connects the end portion of the second linear path portion RTC3 on the −X side and the end portion of the third linear path portion RTC5 on the −X side. The third straight line path portion RTC5 is the work of the first work position WP1 on the −X side and the + X side in the seventh unit area AR27 and the first work position WP1 and the + X side on the −X side in the eighth unit area AR28. It is a path portion extending from the −X side toward the + X side through the non-target position WP1T. The second short-circuit path portion RTC6 does not pass through the non-working positions WP1T and WP2T that are continuously present on the −X side and + X side in the 9th unit region AR29 and the + X side in the 10th unit region AR30, respectively. It is a path portion extending from the + X side end portion of the third linear path portion RTC5 toward the + Y side so as to pass through the second connecting conveyor 23B. The folding path portion RTC7 is centered on the second working position WP2 on the −X side in the 10th unit region AR30, and by folding back against the stroke, the second working on the −X side in the 10th unit region AR30. It 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 regions AR31 and AR32. In such a case, it is impossible to reach the end point position of the third path RTC without passing through the work target non-working position WP2T in the 11th and 12th unit regions AR31 and AR32. Therefore, the movement route setting unit 359 passes through all the second work positions WP2 including the non-work target position WP2T in the 11th and 12th unit areas AR31 and AR32 so as to be continuous from the turn-back route portion RTC7. A fourth straight path portion RTC8 extending from the + X side toward the −X side is set.

In this way, the movement route setting unit 359 sets the work area AR11 on a route that does not pass through the work target positions WP1T and WP2T that are not the target of the setup work in the work positions WP1 and WP2 of each mounting machine 20 to the extent possible. Set as the movement route of the worker within. This makes it possible to shorten the path length of the worker's movement path.
