In the above configuration, when removing the storage box 5 on the box distribution conveyor 1 and replacing it with another type of storage box 5a, press the box exchange switch (not shown).
When pressed, the stopper 27 of the feed control device 7
rises to stop feeding the storage boxes 5 to the box delivery conveyor 1, and all stoppers 23 of the box delivery conveyor 1 descend to stop the delivery of the storage boxes 5 to the box delivery conveyor 1.
is transferred to its end. At the same time, the elevator 15, the box exchange conveyor 11, and the feed control devices 9 and 13 are activated. Then, the storage boxes 5 on the box distribution conveyor 1 are fed into the feed control device 9 one by one by the stopper 31.
At this time, the photoelectric switch A senses the passing container box 5 and inputs a signal to the preset counter 33. The storage box 5 on the feed control device 9 is timing-controlled by the stopper 29 and transferred to the transfer device 15 on the unloading side of the elevator, and when it is raised by the elevator 15 and reaches the upper limit, the photoelectric switch B detects. The extrusion device 17 is activated, and the storage box 5 is pushed out from the elevator carry-out side transfer device 15 onto the box exchange conveyor 11. The storage boxes 5 transferred onto the box exchange conveyor 11 are transferred in the direction of arrow B and stopped by the stopper 25 of the feed control device 13. In this way, the storage boxes 5 on the box distribution conveyor 1 are sequentially transferred onto the box exchange conveyor 11 and held there. Then, when the number of storage boxes 55 detected by photoelectric switch A reaches a preset value set in advance on preset counter 33, stopper 31 stops feeding one storage box 5, and photoelectric switch B switches the elevator to the unloading side. When the last storage box 5 moving up the device 15 is detected, the box exchange conveyor 11, the elevator unloading side transfer device 15, and the feed control devices 9 and 13 are automatically stopped at an appropriate timing. next,
As the stopper 23 of the box distribution conveyor 1 rises, the stopper 27 of the feed control device 7 lowers, and another type of storage box 5a sent from the carry-in side transfer device 19 of the vertical unloading device is delivered by the feed control device 7. It is sent onto conveyor 1.
