Description

Technical Field

[0001] The utility model relates to the technical field of automatic pallet conveying, in particular to an automatic pit-type pallet conveying device. Background Art

[0002] When stacking pallets, personnel need to remove the target pallet from the upper part of the stacked pallets, which is labor-intensive and has the risk of damage to the pallets or hitting personnel. In addition, idle pallets occupy storage space separately. Summary of the invention

[0003] The utility model aims to overcome the shortcomings of the prior art, provide an automatic conveying device for pit-type pallets, reduce the ground space occupied by empty pallets, and improve the conveying efficiency of pallets.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] An automatic conveying device for pit-type pallets comprises a pit, a lifting platform is provided at the bottom of the pit, the top of the lifting platform is used for stacking pallets, movable covers are provided on the left and right sides of the pit opening respectively, and the two movable covers are used to open or close the pit opening of the pit; a tooth fork mechanism is provided on one of the front and rear sides of the pit opening, and an AGV transport robot is provided on the side of the pit opening facing the tooth fork mechanism; the tooth fork mechanism comprises a tooth fork and an XYZ moving module, the tooth fork is connected to the XYZ moving module, and the tooth fork is driven by the XYZ moving module to move in the vertical direction, front-back direction and left-right direction.

[0006] Furthermore, the movable cover is slidably connected to the outside of the pit opening of the pit, and the movable cover is driven by a cylinder or an oil cylinder to move to open or close the pit opening of the pit.

[0007] The utility model adopts the above technical solution, which has the beneficial effects of: stacking pallets in the pit to reduce the ground space occupied by empty pallets. When conveying pallets, the movable cover is opened, the lifting platform rises to the height of a pallet, the tooth fork at the pit mouth extends to lift the first layer of pallets from the ground to a certain height, and then the movable cover is closed and the lifting platform descends. The first layer of pallets falls on the movable cover, and the pallets are transported away by the AGV handling robot after they are filled with products. The above pallet conveying process is efficient and safe, and the pallets are not easily damaged. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] The present invention is further described in detail below with reference to the accompanying drawings and specific implementations:

[0009] Figure 1 It is a front view of the utility model;

[0010] Figure 2 This is a top view of the utility model. DETAILED DESCRIPTION

[0011] like Figure 1-2 As shown, the utility model pit type pallet automatic conveying device comprises a pit 1, and a lifting platform 2 is provided at the bottom of the pit 1, wherein the lifting platform 2 adopts a hydraulic lifting platform 2 in the prior art. The top of the lifting platform 2 is used for stacking pallets 3. The left and right sides of the pit opening of the pit 1 are respectively provided with movable cover plates 4, and the two movable cover plates 4 are used to open or close the pit opening of the pit 1. A tooth fork mechanism 5 is provided on one side of the front and rear sides of the pit opening of the pit 1, and an AGV handling robot 6 is provided on the side of the pit opening of the pit 1 facing the tooth fork mechanism 5.

[0012] Since the spacing between the teeth and forks of the AGV handling robot 6 is fixed, and the path of its forked pallets is also fixed, it is necessary to ensure that the middle wooden block of any size of pallet is located on the center line of the fork of the AGV handling robot 6. Therefore, a tooth fork mechanism 5 is set at the pit mouth to play the role of pallet translation correction, so that the work of placing pallets can be completely separated from manual supervision and realize automation. Specifically, the tooth fork mechanism 5 includes a tooth fork 51 and an XYZ moving module 52. The tooth fork 51 is connected to the XYZ moving module 52, and the XYZ moving module 52 drives the tooth fork 51 to move in the vertical direction, the front-back direction, and the left-right direction. The XYZ moving module 52 adopts the XYZ servo drive mechanism in the prior art. The tooth fork 51 of the above structure has a translation correction function so as to ensure that the center line of pallets of different specifications coincides with the route of the AGV handling robot fork.

[0013] The movable cover plate 4 is slidably connected to the outer side of the pit opening of the pit 1 , and the movable cover is driven by a cylinder or an oil cylinder to move to open or close the pit opening of the pit 1 .

[0014] The working principle of the utility model is as follows: when conveying a pallet 3, the movable cover 4 is opened, the lifting platform 2 rises to the height of a pallet 3, the tooth fork 51 at the pit mouth extends to lift the first layer of pallets 50 cm from the ground and translates it left and right for correction, then the movable cover 4 is closed, the lifting platform 2 descends, the first layer of pallets falls on the movable cover 4, and after the pallet is full of products, it is sent away by the AGV handling robot 6, and the above process is repeated.

[0015] The above describes the specific implementation of the present invention, but those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this implementation without departing from the principle and essence of the present invention, but these changes and modifications are all within the scope of protection of the present invention.
