After the operator places the pallet, he still needs to bend down to align the empty pallet against the baffle. This structure not only wastes efficiency but also makes the operator bend down repeatedly, which does not meet the requirements of ergonomics. Content of the Utility Model

[0024] The utility model will be described in detail below with reference to the drawings and specific embodiments. This embodiment is implemented on the premise of the technical solution of the utility model, and the detailed implementation manner and specific operation process are given, but the protection scope of the utility model is not limited to the following embodiments.

[0025] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not require further definition or explanation in subsequent drawings.

[0026] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0027] Example 1

[0028] The utility model proposes an automatic empty pallet alignment and pushing device to realize the alignment and pushing of empty pallets to the designated position on the paper receiving table. Figure 1 As shown, the device structure includes: a chain conveyor platform 1, an empty pallet 2, a side baffle 3, an imported photoelectric device 4, a pneumatic lifting baffle 5, an electric roller platform 6, a detection photoelectric device 7, a push plate 8, an empty pallet buffer platform 9, an empty pallet size scale 10, a chain conveyor platform motor 11, and an electric roller platform motor 12.

[0029] Among them, the chain conveyor platform 1 and the electric roller platform 6 are arranged in sequence, and the empty pallets 2 of the two are conveyed in opposite directions. The chain conveyor platform 1 and the electric roller platform 6 are provided with pneumatic lifting baffles 5.

[0030] When the pneumatic lifting baffle 5 is lowered, it will be located below the conveying plane of the chain conveyor platform 1 and the electric roller platform 6, and will not affect the conveying of the empty pallet 2 between the two. Figure 2 As shown, when the pneumatic lifting baffle 5 is in the raised state, it will rise above the conveying plane of the chain conveyor platform 1 and the electric roller platform 6, and the distance between its lower plane and the conveying plane of the chain conveyor platform 1 and the electric roller platform 6 is less than the height of an empty pallet 2, thereby separating the chain conveyor platform 1 and the electric roller platform 6.

[0031] The chain conveyor platform 1 is driven by a chain conveyor platform motor 11 provided on one side thereof. A side baffle 3 for aligning one side of the empty pallet 2 is provided on one side along the conveying direction of the chain conveyor platform 1 .

[0032] The pneumatic lift baffle 5 is equipped with an imported photoelectric sensor 4 for detecting empty pallets 2 on the side close to the chain conveyor platform 1, and a detection photoelectric sensor 7 for detecting empty pallets 2 on the side close to the motorized roller platform 6. When the imported photoelectric sensor 4 detects an empty pallet 2, the pneumatic lift baffle 5 descends without affecting the movement of the empty pallet 2 between the chain conveyor platform 1 and the motorized roller platform 6. When the imported photoelectric sensor 4 detects that the empty pallet 2 has left the chain conveyor platform 1, the pneumatic lift baffle 5 rises, separating the chain conveyor platform 1 from the motorized roller platform 6.

[0033] When the empty pallet 2 is completely located on the electric roller table 6, the electric roller table 6 rotates to move the empty pallet 2 back in the direction of the chain plate conveyor table 1. At this time, the empty pallet 2 will be blocked by the pneumatically lifted baffle 5, completing the alignment of the other side of the empty pallet 2.

[0034] On one side of the electric roller table 6, there is a push plate 8 driven by an electric roller table motor 12 to move along a direction perpendicular to the transmission direction of the electric roller table 6, and an empty pallet size scale 10 for adjusting the pushing distance of the push plate 8. On the side of the electric roller table 6 opposite to the push plate 8, there is an empty pallet buffer table 9 for storing the aligned empty pallets 2. For empty pallets 2 of different sizes, the position of the push plate 8 can be adjusted according to the empty pallet size scale 10, so as to ensure that the empty pallet 2 can be sent to the designated position.

[0035] The working principle of the automatic alignment and pushing device for the empty pallet provided by the present utility model is as follows: Place the empty pallet 2 on the chain plate conveyor table 1, close to the side baffle 3. The chain plate conveyor motor 11 rotates, driving the empty pallet 2 through the chain plate conveyor table 1. When the inlet photoelectric sensor 4 detects the empty pallet 2, the pneumatically lifted baffle 5 descends, and the empty pallet 2 moves onto the electric roller table 6; when the inlet photoelectric sensor 4 detects that the empty pallet 2 has left, the pneumatically lifted baffle 5 rises, and the electric roller table 6 rotates to move the empty pallet 2 back until it is blocked by the raised pneumatically lifted baffle 5. At this time, the detection photoelectric sensor 7 detects the empty pallet 2, and the electric roller table 6 stops rotating. The electric roller table motor 12 drives the push plate 8 to start moving, and the push plate 8 pushes the empty pallet 2 onto the empty pallet buffer table 9.

[0036] Based on the above structural features, the present utility model has the following advantages: The chain plate conveyor table 1 is added to transport the empty pallet 2, which can realize the function of automatically transporting and aligning one side of the empty pallet 2; through the electric roller table 6, the pneumatically lifted baffle 5, and the detection photoelectric sensor 7, the automatic alignment of the other side of the empty pallet 2 can be realized, saving manpower; for empty pallets 2 of different specifications, by adjusting the push plate 8 through the empty pallet size scale 10, the empty pallet 2 can be more accurately pushed to the designated position.

[0037] The preferred specific embodiments of the present utility model have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present utility model without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field of the present application based on the concept of the present utility model through logical analysis, reasoning, or limited experiments on the basis of the existing technology should be within the protection scope determined by the claims.
