Referring to fig. 10, a schematic diagram of the operation of the trigger assembly in one embodiment is shown.
Referring to fig. 11 to fig. 15, the following shows a specific operation manner in an embodiment of the present invention: initially, there is a first pallet 40000, the air cylinder 10806 in the main conveyor assembly 10000 is in an extended state, the flap 10802 is raised, the first pallet 40000 is caught behind the flap 10802, and the rest of the equipment is waited to stack the goods on the first pallet 40000, as shown in fig. 11. As shown in fig. 12, when the main conveyor assembly 10000 obtains a signal, the air cylinder 10806 contracts, the first motor 10900 rotates, the stacked first pallet 40000 is conveyed backwards, when the first pallet 40000 is conveyed to the infrared sensor 20400 on the intermediate conveyor assembly 20000, the first pallet 40000 blocks infrared rays emitted by the infrared sensor 20400, and the infrared sensor 20400 transmits a signal to the pallet warehouse to provide the next second pallet 40010, as shown in fig. 13; the motor 10900 continues to operate, and when the first tray 40000 does not shield the infrared rays emitted by the infrared sensor 20400 any more, the air cylinder 10806 is driven to extend, so that the baffle 10802 is lifted, as shown in fig. 14; the motor 10900 is continuously operated, the first tray 40000 continues to be conveyed backward, the first tray 40000 moves onto the unpowered conveyor 30000 and moves backward by inertia, and at the same time, the second tray 40010 stops on the main conveyor due to the blocking of the shutter 10802, as shown in fig. 15. After the first tray 40000 presses down the carrier roller tilted up on the unpowered conveyor 30000, the toggle switch 30600 is toggled to the other side to provide a signal for the first motor 10900, the first motor 10900 stops running, the second tray 40010 waits for goods to be stacked, and the first tray 40000 waits for a forklift to carry away or carry out the next processing. The automatic conveying work is circularly carried out in the way.
While embodiments of the invention have been disclosed above, it is not limited to the applications listed in the description and the embodiments, which are fully applicable in all kinds of fields of application of the invention, and further modifications may readily be effected by those skilled in the art, so that the invention is not limited to the specific details without departing from the general concept defined by the claims and the scope of equivalents.
