It is moved to the empty stage in the first magazine 221 of the accommodating part 22.

  Next, in step a3, the control unit 50 determines whether or not the second information receiving unit 55 has received the supply pallet accommodation information transmitted from the pallet detection unit 41 and the second door body closing detection unit 42. . When the 2nd information reception part 55 has not received supply pallet accommodation information, it progresses to step a4. On the other hand, when the 2nd information reception part 55 receives the supplement pallet accommodation information, it progresses to step a6.

  When the second information receiving unit 55 does not receive the supply pallet accommodation information, the pallet supply / recovery unit 23 is in a state where no supply pallet is stored. Will not be. In such a case, it is assumed that there is no worker around the component supply device 2.

  In a state in which the second information receiving unit 55 has not received the supplemental pallet accommodation information, the accommodation movement control unit 51 controls the accommodation unit moving mechanism 25 to hold the same type of component AA as the component A that has run out of components. The pallet accommodating portion 22 is moved in the Z direction so that 60 is at the same height as the pallet placement surface 24A of the pallet placement table 24 (see FIG. 9B). In step a4, the pallet movement control unit 53 controls the first pallet movement unit 26 and executes the second pallet exchange control.

Further, in the second magazine 222 of the pallet accommodating portion 22, five pallets 60 holding the same kind of parts C, parts CC and parts CCC, and the same kind of parts D and parts DD are housed in advance. Then, it is assumed that the pallet 60 that holds the part A and is accommodated in the first magazine 221 is placed on the pallet placing table 24 and the part A is taken out by the head unit 14. At this time, in the first magazine 221, the support portion 221A supporting the pallet 60 holding the component A is empty. That is, in the first magazine 221, the two support portions 221A are empty.

  First, in step b1, the control unit 50 determines whether or not the second information receiving unit 55 has received the replenishment startable information transmitted from the replenishment start operating unit 232. When the 2nd information reception part 55 receives the supply start possible information, it progresses to step b2. On the other hand, when the 2nd information reception part 55 has not received the supply start possible information, step b1 is repeated. That is, the pallet movement control unit 53 waits for execution of the pallet replenishment control in step b2 until the second information receiving unit 55 receives replenishment startable information.

  When the second information accepting unit 55 accepts replenishment startable information, as shown in FIG. 12A, the replenishment start operation unit 232 is operated by the operator, and the replenishment pallet 60B accommodated in the pallet replenishment collection unit 23 is obtained. In this state, replenishment of the pallet housing part 22 can be started. In the example shown in FIG. 12A, the supply pallet 60 </ b> B holding the part AA is accommodated in the pallet supply / recovery unit 23. In such a state, it is assumed that there is an operator around the component supply device 2. In addition, when the 2nd information reception part 55 receives the supply start possibility information, the 2nd information reception part 55 has received the supply pallet accommodation information before it.

  In a state in which the second information receiving unit 55 has received the replenishment startable information, the storage movement control unit 51 controls the storage unit moving mechanism 25, and the empty stage of the support unit 221A to which the supply pallet 60B is to be supplied is the pallet supply recovery unit. The pallet accommodating portion 22 is moved in the Z direction so as to be at the same height position as the pallet placement surface 23A of 23 (see FIG. 12B). In step b2, the pallet movement control unit 53 controls the second pallet movement unit 28 to execute pallet supply control. When the pallet movement control unit 53 executes the pallet replenishment control, the replenishment pallet 60B accommodated in the pallet replenishment collection unit 23 by the second pallet movement unit 28 is transferred to the pallet accommodation unit 22 as shown in FIG.
