the separated tray falls on the four first bearing plates 93 on the two sliding frames 5, and the falling tray is buffered and prevented from collision under the action of the first compression springs 92 until the tray falls on the first transmission chain 72 stably; then, the two second driving motors 73 synchronously drive the first chain wheels 71 on the two sliding frames 5 to rotate, so as to drive the two first transmission chains 72 to operate, and the tray is transmitted to the next station under the pushing action of the two first push blocks; after one pallet is conveyed, the two driving cylinders 61 drive the two sliding frames 5 to rapidly slide along the directions away from each other, so that an avoidance space 51 is formed between the two sliding frames 5;
at this time, the four delivery chains 2 are conveyed downwards again, the next tray falls on the second bearing plate 103, after the buffer and collision avoidance action of the second compression spring 102, the next tray falls on the second conveying chain 84 smoothly, and the tray is conveyed to another station by the second conveying chain under the pushing action of the two second pushing blocks 841 through the driving of the third driving motor 85;
Whole process for after first transmission device 7 carried a tray, four delivery chain 2 can be down transport two trays rapidly, and then improved the transport efficiency to the tray.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
