[0002] Stacker trucks refer to various wheeled transport vehicles that are used for loading and unloading, stacking, stacking and short-distance transportation of palletized goods.

[0003] Existing stackers are often used to transport bulky and heavy goods. Once the goods are tilted, they need to be adjusted manually. During the adjustment, the goods cannot be lifted by manpower, so the goods can only slide on the placement board, and the surface of the cargo box may be scratched, affecting the logo on the surface of the cargo box and affecting the transportation of the goods.

[0030] Refer to Figure 4, two circular grooves 8 are symmetrically opened at the top of the second extending fork 7. A first cylinder 9 is rotatably connected inside the circular groove 8. A gear groove 10 is opened inside the second extending fork 7 and below the first cylinder 9. A first rotating motor 11 is arranged inside the second extending fork 7 and on the right side of the first cylinder 9. The output shaft of the first rotating motor 11 extends into the gear groove 10, and a first gear 12 is arranged on the output shaft of the first rotating motor 11. A second gear 13 is arranged on the circumferential side of the first cylinder 9 and inside the gear groove 10, and the second gear 13 meshes with the first gear 12. A hydraulic cylinder 14 is fixedly installed at the bottom of the inner cavity of the first cylinder 9. The top of the hydraulic cylinder 14 is fixedly installed with a second cylinder 15. A second rotating motor 16 is fixedly installed on the left side of the inner cavity of the second cylinder 15. The output shaft of the second rotating motor 16 extends to the right side of the inner cavity of the second cylinder 15. A roller 17 is fixedly installed on the circumferential side of the output shaft of the second rotating motor 16. A roller hole 18 is opened at the position corresponding to the roller 17 at the top of the first cylinder 9. The four first rotating motors 11 and the four second rotating motors 16 are divided into two groups, and the same group moves synchronously. Such a design enables the worker to correct the inclined goods while stacking the goods, ensuring the accuracy of the goods stacking and improving the stacking efficiency.

[0031] Refer to Figure 3 and Figure 4 , this solution further includes a discharging plate 19 that is matched with the stacker. Adjusting holes 20 corresponding to the four circular grooves 8 are opened at the top of the discharging plate 19. When the roller 17 rises to the limit position, the top of the roller 17 will be higher than the discharging plate 19.

[0033] A. Place the discharging plate 19 carrying the goods on the lifting plate 4. It should be noted that when placing the goods on the lifting plate 4, a forklift is often used. If the forklift runs too fast, it is easy to cause the goods to tilt.

[0034] B. If the goods are skewed, adjust them. Taking the direction of the slide rail as the X-axis direction, the specific process is as follows:

[0035] a1: Control the two groups of first rotating motors 11 to rotate, so that the two groups of rollers 17 are in the same direction as the X-axis. Open the hydraulic cylinder 14. The hydraulic cylinder 14 drives the two groups of rollers 17 to rise, so that the top of the rollers 17 contacts the bottom of the goods and lifts the goods a small distance. According to the different tilting directions of the goods, control the two groups of rollers 17 to rotate in the opposite direction to make the goods parallel to the X-axis. The angles of the two groups of rollers 17 do not necessarily need to be parallel to the X-axis. According to the usage experience, the two groups of rollers 17 can also be adjusted by themselves.

[0036] b2: Control the rotation of the two groups of first rotating motors 11 to make the two groups of rollers 17 perpendicular to the X axis in the same direction, control the two groups of rollers 17 to rotate in the same direction, control the rotation of the two groups of rollers 17, and send the goods element to a suitable position;

[0038] D. Open the lifting device 3, transport the goods to the designated height, extend the second goods-extending fork 7, and the lifting device 3 descends a short distance to place the discharging plate 19 on the shelf.

[0039] E. Control the second goods-extending fork 7 to return to the initial position and restore the two groups of rollers 17 to the initial position, which is convenient for the next adjustment.
