Further, the supply / recovery section moving mechanism 31 moves the pallet supply / recovery section 23 independently of the second storage section 222 in a region on the + Z direction side of the second magazine pull-out position R2aa in the Z-axis direction. be able to.

  When the second storage part 222 is stopped at the second magazine pull-out position R2aa in the second storage part movement area R2, the operator opens the second door 214B and moves the second magazine from the second magazine storage housing 222B to the second magazine. The exchange work can be performed by pulling out 222A. Here, since a plurality of pallets 60 are accommodated in the second magazine 222A, the operator can perform an exchange operation of exchanging the plurality of pallets 60 at a time. Therefore, it is possible to increase the efficiency of the work of replacing the pallet 60 by the operator.

  As shown in FIG. 10, when the pallet 60 is moved between the first storage section 221 and the first table 24 by the first pallet moving section 27, the first magazine supporting the pallet 60 is used. The first moving mechanism 301 stops the first storage section 221 so that the first support section 221Aa of the first storage section 221A is located at the first position R12a corresponding to the loading / unloading position of the pallet 60.

  In the present embodiment, in the Z-axis direction, a first magazine pull-out position R1aa (a position where the first door body 214A is arranged in the Z-axis direction) in the first storage unit movement region R1, and a second storage unit movement region. The second magazine pull-out position R2aa in R2 (the position where the second door body 214B is arranged in the Z-axis direction) is set to a position sandwiching the first position R12a. The first position R12a is, as described above, when the pallet 60 is moved between the pallet accommodating section 22 and the first table 24 by the first pallet moving section 27, and the pallet 60 is moved in and out of the pallet accommodating section 22.

With such a configuration, one of the first storage unit 221 and the second storage unit 222 is stopped at the magazine pull-out position, and the magazine is drawn out by the operator, and the plurality of pallets 60 are exchanged collectively. Even while the replacement operation is being performed, the other storage unit can be moved within the storage unit movement area including the first position R12a. Therefore, when the operator replaces the pallet 60 in one of the storage units, the movement of the pallet 60 by the first pallet moving unit 27 is continuously stopped between the other storage unit and the first table 24 without stopping. It can be carried out.

  Further, in the Z-axis direction, a first magazine pull-out position R1aa in the first storage unit movement region R1 and a second magazine pull-out position R2aa in the second storage unit movement region R2 sandwich the fourth position R12b. It is desirable that it is set to the position. The fourth position R12b corresponds to a position where the pallet 60 is moved in and out of the pallet storage unit 22 when the pallet 60 is moved between the pallet storage unit 22 and the second table 28 by the second pallet moving unit 29. . With such a configuration, one of the first storage unit 221 and the second storage unit 222 is stopped at the magazine pull-out position, and the magazine is drawn out by the operator, and the plurality of pallets 60 are exchanged collectively. Even while the replacement operation is being performed, the other storage unit can be moved within the storage unit movement area including the fourth position R12b. Therefore, when the operator replaces the pallet 60 in one of the storage units, the movement of the pallet 60 by the second pallet moving unit 29 is continuously stopped between the other storage unit and the second table 28 without stopping. It can be carried out.

  FIG. 11 is a diagram for explaining an operation when the pallet 60 is taken in and out of the pallet supply / recovery section 23 in the component supply device 2. An operator performs a replenishment operation of replenishing the pallet replenishing and collecting unit 23 with a new pallet 60 (alternate pallet holding a component that is out of component) according to the mounting operation status of the component 70 on the board in the component mounter 1. In this case, the component supply device 2 operates as follows. The supply / recovery section moving mechanism 31 moves the pallet supply / recovery section 23 in the Z-axis direction, and the pallet supply position R3aa in the supply / recovery section movement area R3 (the position where the third door body 214C is arranged in the Z-axis direction). To stop. At this time, the first moving mechanism 301 and the second moving mechanism 302 independently of the pallet supply / recovery section 23 in the first housing in a region on the −Z direction side of the pallet supply position R3aa in the Z-axis direction. The part 221 and the second accommodation part 222 can be moved.

  When the pallet supply / recovery section 23 is stopped at the pallet supply position R3aa in the supply / recovery section moving area R3, the operator opens the third door 214C and removes the supply / recovery section main body 231 from the supply / recovery section housing housing 232. The pallet can be drawn out and replenished with a new pallet 60 to the pallet replenishing and collecting section 23.

  As shown in FIG. 11, when the pallet 60 is moved between the first storage section 221 and the first table 24 by the first pallet moving section 27, the first magazine supporting the pallet 60 is used. The first moving mechanism 301 stops the first storage section 221 so that the first support section 221Aa of the first storage section 221A is located at the first position R12a corresponding to the loading / unloading position of the pallet 60. When the pallet 60 is moved between the second storage section 222 and the first table 24 by the first pallet moving section 27, the second support section 222Aa of the second magazine 222A supporting the pallet 60 is used. Is moved to the first position R12a corresponding to the position where the pallet 60 is put in and out, and the second moving mechanism 302 stops the second storage portion 222.

  In addition, when the pallet that has run out of components is moved from the first table 24 to the pallet replenishing and collecting unit 23 by the first pallet moving unit 27, and the pallet that has run out of components is collected in the pallet replenishing and collecting unit 23, the component supply device 2 sets the following. Works like that. The supply / recovery section moving mechanism 31 moves the pallet supply / recovery section 23 that has collected the component pallet in the Z-axis direction and stops at the pallet supply position R3aa in the supply / recovery section movement area R3. At this time, the first moving mechanism 301 and the second moving mechanism 302 independently of the pallet supply / recovery section 23 in the first housing in a region on the −Z direction side of the pallet supply position R3aa in the Z-axis direction. The part 221 and the second accommodation part 222 can be moved.

  When the pallet supply / recovery section 23 is stopped at the pallet supply position R3aa in the supply / recovery section moving area R3, the operator opens the third door 214C and removes the supply / recovery section main body 231 from the supply / recovery section housing housing 232. By pulling out the pallet, the pallet replenishing and collecting section 23 can take out the part pallet collected.

  In the present embodiment, a pallet supply position R3aa where a new pallet 60 is supplied to the pallet supply / recovery unit 23 or a pallet-out pallet collected by the pallet supply / recovery unit 23 is taken out. It is set outside the accommodation area movement area that is the movement area. For this reason, even when the pallet supply / recovery section 23 is stopped at the pallet supply / recovery position R <b> 3 aa and the worker is performing a supply operation to the pallet supply / recovery section 23 or a removal operation from the pallet supply / recovery section 23. The pallet storage section 22 is movable within the storage section movement area. Therefore, at the time of the work of replenishing or removing the pallet 60 by the operator, the movement of the pallet 60 by the first pallet moving unit 27 is continuously performed between the pallet storage unit 22 and the first table 24 without stopping. be able to.

  As described above, in the component supply device 2 according to the present embodiment, the supply and collection unit moving mechanism 31 moves the pallet supply and collection unit 23 independently of the pallet storage unit 22. That is, the movement operation of the pallet storage unit 22 by the storage unit movement mechanism 30 and the movement operation of the pallet supply and collection unit 23 by the supply and collection unit movement mechanism 31 are not linked. Therefore, when the pallet supply / recovery section 23 moves, the first pallet is moved between the pallet storage section 22 stopped at the first position R12a in the storage section moving area and the second position R12aa on the first table 24. The movement of the pallet 60 by the moving unit 27 can be continued without stopping. Accordingly, the component 70 can be efficiently supplied to the head unit 3 of the component mounter 1 while being held on the pallet 60, and the component pallet can be efficiently collected.

  Next, the electrical configuration of the component supply device 2 will be described. FIG. 12 is a block diagram illustrating an electrical configuration of the component supply device 2.

  The first accommodation movement control unit 401 controls the first movement mechanism 301 of the accommodation part movement mechanism 30. Thus, the movement of the first storage unit 221 in the pallet storage unit 22 in the Z-axis direction is controlled. The second accommodation movement control unit 402 controls the second movement mechanism 302 of the accommodation part movement mechanism 30. Thereby, the movement of the second storage section 222 in the pallet storage section 22 in the Z-axis direction is controlled. The supply and collection movement control unit 403 controls the supply and collection unit movement mechanism 31. Thus, the movement of the pallet supply / recovery section 23 in the Z-axis direction is controlled. The first table movement control unit 404 controls the table movement mechanism 26. Thereby, the movement operation of the first table 24 is controlled. The first pallet movement control unit 405 controls the first pallet movement unit 27. The second pallet movement control unit 406 controls the second pallet movement unit 29.

  The parts shortage determination unit 408 determines that one pallet 60 stored in the pallet storage unit 22 is moved to the first table 24 by the first pallet moving unit 27, and the first pallet moving unit 27 moves the one pallet 60 on the one pallet 60 by the head unit 3. After the part 70 of the one pallet 60 is taken out, it is determined whether the one pallet 60 has run out of parts. In the present embodiment, the component shortage determination unit 408 counts the occurrence of component shortage on the one pallet 60 by counting the remaining number of the components 70 held on one pallet 60 placed on the first table 24. Is determined. The notifying unit 51 is configured to notify the out-of-part warning information when the remaining number of components counted by the out-of-part determining unit 408 reaches a predetermined threshold.

  Next, the operation of supplying and collecting the pallet 60 in the component supply device 2 will be described. 13A, 13B, and 13C are diagrams illustrating an example of the supply and collection operation of the pallet 60 in the component supply device 2.

  The operation of supplying and collecting the pallet 60 in the component supply device 2 is executed based on the instruction received by the receiving unit 407. In the example shown in FIGS. 13A, 13B, and 13C, three pallets 60 holding different types of components A, B, and C are stored in the first storage unit 221 in advance. Further, three pallets 60 holding different types of components D, E, and F, respectively, are stored in the second storage portion 222 in advance. Then, it is assumed that the instruction to supply the component A has been received by the receiving unit 407.

  First, the control unit 40 specifies the first storage unit 221 that stores the pallet 60 holding the component A based on the component management information stored in the storage unit 51, and transmits the first storage unit 221 to the first storage movement control unit 401.
