Description

Technical Field

[0001] The utility model relates to the field of pallet loading, in particular to a double-station synchronous lifting pallet loader. Background Art

[0002] In the field of logistics, warehousing and transportation, pallets, as a standardized cargo carrying tool, are widely used in the loading, unloading, storage and transportation of various goods. The use of pallets has greatly improved the transportation efficiency of goods and the storage capacity of warehouses. During production and transportation, since the heights of pallet conveyors vary, it is necessary to lift the pallet loader to a certain height before transportation. In the prior art, a cylinder is usually used to push the slider of the lifting plate to slide along the guide rail to complete the lifting. However, the use of the cylinder requires an air compressor to provide continuous power, so the reciprocating motion of the lifting plate will be relatively slow. When the height of the conveyor line changes, the lifting mechanism is not flexible enough and has low precision, which affects work efficiency. Utility Model Content

[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0016] A double-station synchronous lifting pallet loader, such as Figure 1-3As shown, it includes a body 1, the body 1 includes a base 2 and a top plate 3, the base 2 is connected to the top plate 3 through multiple groups of connecting columns 4, the body 1 is provided with two groups of lifting mechanisms 5, the lifting mechanism 5 includes a lifting plate 501, a tray 6 is placed on the lifting plate 501, both ends of the lifting plate 501 have ear plates, the ear plates are threadedly connected with a screw rod 502, and the lower end of the screw rod 502 has a driven gear 505; the lifting mechanism 5 also includes a motor 503 fixedly connected to the bottom of the base 2, the motor 503 is rotatably connected with a driving gear 504, and the driving gear 504 drives the driven gear 505 to rotate through a chain 506; when it is necessary to adjust the height of the pallet loader according to the height of the conveyor line, the controller is used to adjust the height of the pallet loader according to the height of the conveyor line. Start the motor 503 to rotate forward, the motor 503 drives the driving gear 504 to rotate, the driving gear 504 drives the chain 506 to rotate, and the rotation of the chain 506 drives the driven gear 505 to rotate, and the driven gear 505 drives the two screw rods 502 to rotate in the same direction, and the screw rods 502 drive the ear plate of the lifting plate 501 to move upward, that is, drive the lifting plate 501 to move upward; start the motor 503 to rotate reversely, and the lifting plate 501 moves downward; thereby, the tray 6 on the lifting plate 501 can be lifted flexibly and with high precision, so as to be adjusted to different heights, and then the tray is moved to the conveyor line by the manipulator to complete the conveying; the double-station design can meet the tray conveying work of two production lines at the same time, which is easy to operate and can save space.

[0017] In the utility model, preferably, the width of the ear plates at both ends of the lifting plate 501 is greater than the width of the lifting plate 501, and is in an "I" shape. The ear plates have through holes for the connecting columns 4 to pass through, so that the connecting columns 4 pass through the ear plates, so that the lifting plate 501 is evenly stressed and more stable, and has greater bearing capacity.

[0018] In the present invention, preferably, there are eight groups of connecting columns 4, which can not only stably support the base 2 and the top plate 3 but also make the lifting plate 501 more stable.
