Technical Field

The utility model relates to a inhale paper mechanism and horizontal collating machine belongs to the lithography apparatus field.

Background

The horizontal collating machine comprises a frame, and a paper lifting mechanism, a paper suction mechanism, a paper clamping mechanism and a paper conveying mechanism which are arranged on the frame. The paper lifting mechanism is used for placing the stacked paper and lifting the stacked paper in the working process of the assembling machine, and the stacked paper is lifted up to facilitate the paper suction mechanism to suck the paper; the paper clamping mechanism is used for clamping the paper sucked by the paper sucking mechanism and sending the paper to the paper conveying mechanism; the paper conveying mechanism advances one station after receiving one paper (one page), and a plurality of paper lifting mechanisms on the horizontal collating machine are arranged in a straight line and are used for placing paper piles with different page numbers on different paper lifting mechanisms according to the page number sequence, so that continuous collating can be realized.

In the prior art, a paper suction mode of a paper suction mechanism of a horizontal collating machine is to suck paper vertically, namely, a paper stack is horizontally placed on a paper lifting mechanism, the paper suction mechanism is arranged above the paper stack, a suction cup arranged on the paper suction mechanism vertically moves downwards to suck the uppermost paper of the paper stack, then moves upwards, and a paper frame is moved away by a paper clamping mechanism. The vertical suction paper is divided into the following two forms:

first, the paper suction mechanism is provided with suckers above four corners of the paper stack, so that the four corners of the paper are sucked when the paper is sucked, and the whole paper is sucked. The mode is easy to cause the condition of double sheets, when the paper stack is relatively orderly and flat, air hardly exists between the adjacent sheets, the weight of a single sheet of paper is light, the suction cup moves vertically, the adjacent sheets with completely overlapped outlines are easy to suck at the same time, although the suction cup sucks only the first sheet on the paper stack, the second sheet is taken away by the first sheet due to the action of atmospheric pressure.
