[0036] By adopting the above technical solution, the trays at the ends of the upper roller line 3 and the single-layer roller line 8 are limited, thereby preventing them from sliding out of the roller line.

[0037] Example 2

[0038] The present embodiment differs from the first embodiment in that: specifically, a sliding rod 162 is connected to the end side of the movable plate 16 , and a sliding groove 151 corresponding to the sliding rod 162 is provided on the wedge-shaped push plate 15 .

[0044] The working steps of this utility model are as follows:

[0045] 1. An employee uses a forklift to move a pallet filled with product boxes to the upper roller line 3, which then transports the pallet to the end where the elevator 9 is located.

[0046] 2. After being transported to the position of the upper full material sensor 4, the cylinder 14 of the upper limit assembly 13 of the upper roller line 3 is actuated to push the wedge-shaped push plate 15 forward, causing the movable plate 16 to rise and block the pallet;

[0047] 3. The elevator 9 drives the single-layer roller line 8 to move to a horizontal position with the upper-layer roller line 3, and then the limit assembly 13 on the upper-layer roller line 3 is reset, and the pallet is conveyed to the single-layer roller line 8. When the single-layer feeding sensor 5 detects the incoming pallet, the single-layer roller line 8 starts. Under the joint action of the single-layer roller line 8 and the upper-layer roller line 3, the pallet is conveyed to the single-layer roller line 8. When the pallet is conveyed to the position of the intermediate sensor 6, the upper-layer roller line 3 stops running. At this time, the single-layer roller line 8 continues to run. When the pallet is conveyed to the position of the limit sensor 7, the single-layer roller line 8 stops running, the pallet stops, and the limit assembly 13 on the single-layer roller line 8 acts to limit the pallet.

[0048] 4. The lift 9 continues to rise to a height that is convenient for the employees to operate. The employees take away the product boxes on the tray one by one. After taking a certain number of product boxes, the employees operate the lift 9 to continue to rise to a height that is convenient for operation until all the product boxes are taken away.

[0049] 5. Then the elevator 9 descends to the level of the single-layer roller line 8 and the lower-layer roller line 2. The single-layer roller line 8 rotates in the opposite direction to transfer the pallet to the lower-layer roller line 2. When the lower-layer feeding sensor 10 detects the incoming pallet, the lower-layer roller line 2 starts and transfers the empty pallet to the lower-layer roller line 2 together with the single-layer roller line 8. When the single-layer feeding sensor 5 fails to detect the pallet, the single-layer roller line 8 stops running, while the lower-layer roller line 2 continues to run until the lower-layer feeding sensor 10 fails to detect the pallet.

[0050] 6. When the lower layer full material sensor 12 detects a pallet, the equipment alarms to remind employees to remove the empty pallet.

[0051] To sum up, the utility model conveys pallets filled with product boxes through the upper roller line 3, conveys empty pallets through the lower roller line 2, and drives the single-layer roller line 8 to connect through the elevator 9. Employees do not need to frequently move full pallets and empty pallets, which improves work efficiency and reduces labor intensity; the utility model drives the single-layer roller line 8 to rise and fall through the elevator 9, so that the product boxes on the upper layer can correspond to a height that is convenient for employees to pick up, thereby avoiding employees from frequently bending over and reducing labor intensity; the utility model installs two symmetrically arranged limit assemblies 13 at the ends of the upper roller line 3 and the single-layer roller line 8, respectively, for limiting the pallets at the ends of the upper roller line 3 and the single-layer roller line 8, so as to prevent them from slipping out of the roller line.

[0052] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
