[0056]
Thus, when the mounting of electronic components on the pallet b by the first set of advance / retreat means 26 is completed, the mounted pallet b is pulled out from the transport means 3 by the first set of advance / retreat means 26, and instead, the second set The pallet b waiting in the elevating body 25 is sent to the conveying means 3 by the advance / retreat means 26 and a predetermined electronic component is mounted on the electronic component mounting machine S.
[0057]
During the mounting of electronic components on the pallet b fed by the second set of advance / retreat means 26, the relay means 2 raises / lowers the lifting / lowering body 25, and the empty pallet b held by the first set of advance / retreat means 26 is removed. When the pallet b containing new electronic components is taken into the lifting / lowering body 25 by the advance / retreat means 26, the pallet b supplied to the transport means 3 by the second set of advance / retreat means 26 is returned to the empty receiving shelf 4 of the storage means 1. When the mounting of the electronic parts is completed, the next pallet b can be supplied immediately, the waiting time is shortened and there is no time loss, and the main electronic parts are efficiently mounted.
[0058]
In addition, the empty pallet b in which the electronic component mounting in the storage unit 1 has been completed is newly added from the insertion side of the storage unit 1 sequentially even when the electronic component mounting machine S and the relay unit 2 and the transport unit 3 are in operation. 7 can be replaced with a pallet b containing various electronic parts. In the case shown in FIG. 7A, each receiving shelf 4 is replaced one by one, and in the case shown in FIG. The entire body 16 can be removed from the frame 1a and the pallet b can be exchanged outside the machine.
[0059]
The relay unit 2 may be a single unit that takes out one pallet b from the storage unit 1 and returns the empty pallet b to the storage unit 1 again for storage. If the supply part m of the machine S has a plurality of placement parts for the pallets b, the pallet b can be taken out from the storage means 1 even when the electronic parts are being mounted on the printed circuit board of the electronic part mounting machine S. In the mounting machine S, there is no waiting time for replacing the pallet b.
[0060]
【The invention's effect】
As described above, according to the present invention, the storage means storing the pallet is fixed, and the relay means for feeding the pallet to the supply part of the electronic component mounting machine is interposed, and the relay means is provided so as to be movable in the vertical direction. Thus, when supplying and taking out the pallet from the supply unit, the time can be greatly reduced, and the main electronic components can be mounted smoothly .
[0061]
Since the pallet can be replaced while the mounting machine and the supply device are in operation, the operation stoppage of the electronic component mounting machine for the pallet replacement is reduced as much as possible.
[0062]
Since the relay means can support a plurality of pallets, the supply time and the mounting time can be overlapped, and the waiting time due to the pallet replacement of the mounting machine is shortened.
[0063]
Since the pallet storage means side does not move, maximum pallet storage can be performed regardless of weight and height, and it is possible to cope with long-time work when the mounting machine is automated. Pallet arrangement considering the mounting order of components is possible.
[0064]
By providing a restricting means for positioning the pallet at the time of delivery of the pallet on the receiving shelf of the frame, the pallet can be set at a predetermined frame position.
