Description

Technical Field

[0001] The present invention relates to the technical field of warehouse stackers, and in particular to an automated stereoscopic warehouse stacker and a method thereof. Background Art

[0002] Large warehouses use stackers to load and unload goods. The stacker sets up floor rails and stepping units, and installs a lifting unit on the stepping unit, thereby setting up a telescopic fork to realize the transfer and stacking of goods. It can realize stacking and loading and unloading of goods on a unit basis in the warehouse. Therefore, when stackers are used for loading and unloading in warehouses, a single longitudinal track and multiple transverse tracks are usually set up, so that goods can be loaded at the entrance and exit and transferred at the transverse and longitudinal tracks, so as to realize the loading and unloading of goods on different rows of shelves.

[0003] However, the fork mechanism of the existing stacker usually adopts a one-way stepping mechanism that imitates the forklift shelf, so that the stacker can only complete the loading and unloading of goods on a single-sided shelf. This means that a single row of shelves in the warehouse needs to be equipped with a set of stackers and corresponding track units, which increases the cost of warehouse construction. Therefore, improving the structure of the stacker, increasing the loading and unloading efficiency and reducing the construction cost has become a project worthy of research and development.

Then, push and adjust the position of the cargo pallet. When unloading from the left side, align the left side of the cargo pallet with the left end of the fork (2). When unloading from the right side, align the left side of the cargo pallet with the left end of the fork (2). The right side of the pallet is aligned with the right end of the fork (2). After the position of the cargo pallet is adjusted, the load-bearing frame (17) is lowered so that the support roller (18) is retracted into the base (1) and the support roller (18) is lower than the bridge frame (15), so that the cargo pallet is lowered and is again supported on the fork (2); then, the front and rear positions of the base (1) are adjusted by the horizontal stepping unit (3-2), and the upper and lower positions of the base (1) are adjusted by the lifting stepping unit (3-4), so that the base (1) drives the cargo to move to the corresponding unloading unit;When the fork (2) is extended to the left to unload, the connecting seat (8) is pushed by the electric telescopic rod (4-3), so that the connecting seat (8) drives the positioning pin (4-4) and the transmission pin (9) to move, so that the positioning pin (4-4) on the left connecting seat (8) is pulled out from the positioning hole (4-5) at the left end of the support plate (4-1), and the transmission pin (9) on the left connecting seat (8) is moved out from between the limit blocks (5-4) on the stepping belt (5-3) and then snapped into the positioning frame (12), so that the right connecting seat (8) ) is inserted into the positioning hole (4-5) at the right end of the support plate (4-1), and the transmission pin (9) on the right connecting seat (8) moves and is inserted between two adjacent limit blocks (5-4) on the stepping belt (5-3). Then, the servo motor (5-5) drives the driving shaft (5-1) to rotate, so that the driving shaft (5-1) drives the driving roller (5-2) to rotate counterclockwise, so that the driving roller (5-2) drives the upper belt surface of the stepping belt (5-3) to move leftward, and the stepping belt (5-3) is driven by the driving roller (5-2). The limit block (5-4) on the right side of the connecting seat (3) is clamped with the transmission pin (9) on the right side of the connecting seat (8), thereby driving the right side of the supporting frame (7) and the supporting seat (4-2) to move to the left through the transmission pin (9) on the right side of the connecting seat (8), so that the right side of the supporting frame (7) slides to the left on the supporting slide rail (6), and the right side of the supporting seat (4-2) is driven to move to the left through the positioning pin (4-4) on the right side of the connecting seat (8), so that the right side of the supporting seat (4-2) pushes the support plate (4-1) on the fork (2). ) moves to the left, that is, drives the fork (2) to extend to the left, and the fork (2) drives the pallet loaded with goods to move to the left and send it into the cargo unit to complete the unloading of the goods. When the fork (2) is extended to the right to unload the goods, the left support frame (7) is connected to the stepping belt (5-3) by transmission, and the right support frame (7) is separated from the stepping belt (5-3), and the upper belt surface of the stepping belt (5-3) is driven to move to the right, so that the fork (2) is extended to the right and drives the pallet loaded with goods to complete the unloading of the goods. ;
