Pressing paper unloading method

Abstract

The present invention discloses a compacting paper unloading method, which includes the following steps: ① the paper unloading platform moves to the left and approaches the paper feeding platform, and the paper pile is pushed to the paper unloading platform and clamped by a paper clamping device; ② the paper unloading platform does not move, and the paper clamping device drags the clamped paper pile to the right horizontally; ③ the paper unloading platform and the paper clamping device move to the right synchronously to the paper unloading station, and the paper unloading platform descends a distance so that its bottom is close to the stacked paper; ④ the paper unloading platform moves to the left, and when the paper unloading platform leaves or is about to leave the paper pile, the paper pressing board presses the paper pile on the stacked paper; ⑤ the paper clamping device releases the paper pile, and the paper unloading platform and the paper clamping device leave from the left and right ends of the paper pile; ⑥ the paper pressing board releases the compression on the paper pile, and the paper pressing board, the paper unloading platform and the paper clamping device return to their original positions, waiting for the next paper unloading action. The above compacting paper unloading method is suitable for paper with a light texture and a smooth surface, which prevents the drifting and displacement of the upper paper during each paper unloading action, thereby ensuring the quality of paper unloading.

Description

Technical Field

[0001] The present invention relates to a paper unloading method. Background Art

[0002] After the paper cutter cuts the paper, the paper needs to be unloaded and stacked by the paper unloader. In the process of unloading and stacking paper, the paper unloader of the prior art, for example, uses the technology of patent number 202010040729.7 applied by the applicant in 2020 and the patent name "a method of unloading paper" to unload paper. If the paper is thin and light with a smooth surface, then when the last paper clamping device and the unloading platform are pulled out of the paper pile, the top few sheets of paper in the paper pile are prone to drift and shift, and the quality of unloading cannot be guaranteed. Summary of the invention

[0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a compacting paper unloading method which is suitable for thin paper with a smooth surface, prevents the upper paper from drifting and shifting during each paper unloading action, and ensures the quality of paper unloading.

[0004] The present invention is implemented by the following technical solutions:

[0005] The paper unloading method for compacting and unloading paper is characterized in that it comprises the following steps: ① the paper unloading platform moves to the left and approaches the paper feeding platform, and the paper pile is pushed to the paper unloading platform and clamped by the paper clamping device; ② the paper unloading platform does not move, and the paper clamping device drags the clamped paper pile horizontally to the right, and the paper pile completely falls onto the paper unloading platform; ③ the paper unloading platform and the paper clamping device move to the right synchronously to the paper unloading station, and the paper unloading platform descends a distance so that its bottom approaches the stacked paper; ④ the paper unloading platform moves to the left, and when the paper unloading platform leaves or is about to leave the paper pile, the paper pressing board moves to press the paper pile tightly on the stacked paper; ⑤ the paper clamping device releases the paper pile, and the paper unloading platform and the paper clamping device leave from the left and right ends of the paper pile, so that the paper pile is neatly stacked on the stacked paper; ⑥ the paper pressing board releases the pressure on the paper pile, and the paper pressing board, the paper unloading platform and the paper clamping device return to their original positions, waiting for the next paper unloading action.

[0006] The key to the paper unloading method using the above technical solution is that when the paper clamping device releases the paper pile and the paper unloading platform and the paper clamping device leave from the left and right ends of the paper pile, the paper pressing paper moves in advance to press the paper pile on top of the stacked paper. In this way, when the paper unloading platform and the paper clamping device leave from the left and right ends of the paper pile, since the paper pile is always pressed, no matter whether the texture of the paper is thin or the surface is smooth, the top paper of the paper pile will not drift or shift, thereby ensuring the quality of paper unloading. BRIEF DESCRIPTION OF THE DRAWINGS

[0007] The present invention has the following drawings:

[0008] Figure 1The structure of the paper unloading device of the present invention is shown in FIG. Figure 1 ,

[0009] Figure 2 The structure of the paper unloading device of the present invention is shown in FIG. Figure 2 . DETAILED DESCRIPTION

[0010] As shown in the figure, the paper unloading machine for compacting and unloading paper of the present invention comprises a paper unloading platform 1 and a paper clamping device. The paper unloading platform 1 can slide left and right and is arranged on the lifting beam 2 and is driven by the platform servo motor. The lifting beam 2 is pushed up and down by the hydraulic oil cylinder 3. The paper clamping device comprises a paper clamping cantilever 9. The paper clamping cantilever 9 can slide left and right and is arranged on the lifting beam 2 and is driven by the cantilever servo motor. A paper stopper 13, a paper clamping block 14 and a paper pressing block are installed on the paper clamping cantilever 9. The paper clamping block 14 is fixedly connected to the bottom of the paper stopper 13. The paper stopper 13 is made on the paper clamping cantilever 9. The up and down movement is driven by the paperboard blocking cylinder 10, the paper pressing block is arranged above the paper clamping block 14, and the up and down movement of the paper pressing block on the paper clamping cantilever 9 is driven by the paper pressing block cylinder. The paper pressing block is provided with two groups, inner and outer, the inner paper pressing block 7 is driven by the inner paper pressing block cylinder 8, and the outer paper pressing block 12 is driven by the outer paper pressing block cylinder 11. The inner and outer paper pressing block cylinders are fixedly installed on the paper clamping cantilever 9. At the paper unloading station, a paper pressing paper 5 is arranged above the paper unloading platform. The paper pressing paper 5 is driven by the paper pressing paper cylinder 6 to move up and down, and the paper pressing paper cylinder 6 is driven by the longitudinal cylinder 4 to move forward and backward.

[0011] The present invention is a paper unloading method for pressing and unloading paper, comprising the following steps: ① the paper unloading platform moves to the left and approaches the paper feeding platform, and the paper pile is pushed to the paper unloading platform and clamped by the paper clamping device; ② the paper unloading platform does not move, and the paper clamping device drags the clamped paper pile A to the right horizontally, and the paper pile completely falls onto the paper unloading platform; ③ the paper unloading platform and the paper clamping device move to the right synchronously to the paper unloading station, and the paper unloading platform descends a distance so that its bottom is close to the stacked paper; ④ the paper unloading platform moves to the left, and when the paper unloading platform is about to leave the paper pile, the paper pressing paper acts to press the paper pile on the stacked paper; ⑤ the paper clamping device releases the paper pile, and the paper clamping device and the paper unloading platform move away from each other in the opposite direction, and the paper unloading platform and the paper clamping device leave from the left and right ends of the paper pile, so that the paper pile A is neatly stacked on the stacked paper; ⑥ the paper pressing paper releases the pressing of the paper pile, and the paper pressing paper, the paper unloading platform and the paper clamping device return to their original positions, waiting for the next paper unloading action.
