A starting method for vertical insertion of a scraper holder

Abstract

The invention discloses a start-up method for vertical insertion of a scraper frame. The method divides the insertion start-up control of the scraper frame into three modes: no advance and delayed start, advanced start and delayed start. The requirement matches different startup modes, adapts to different needs of actual production, can avoid the problem that the scraper frame hits or cannot catch the carton due to mechanical structure and other reasons, and improves the insertion stability of the scraper frame; The control signal is detected in real time through the counting photoelectric switch and the measuring encoder of the feeding belt, which is not affected by the type of carton and the conveying speed, and the control is stable, effective and reliable.

Description

technical field [0001] The invention relates to the technical field of stacking in carton production, in particular to a starting method for vertical insertion of a scraper. Background technique [0002] The counting and ejecting unit is an important unit of the box gluing machine. It is a device that further stacks, corrects, counts, separates, and conveys the cartons formed by the folding unit. In order to achieve uninterrupted stacking, separation and transportation of paper bundles, it is necessary to control the scraper to insert between the last carton of the old paper bundle and the first carton of the new paper bundle after the stacking of the old paper bundle is completed, and separate the new paper Bundles and old paper bundles, and reach the upper surface of the old paper bundles, clamp the old paper bundles with the paper holder, and transport the old paper bundles out. [0003] The traditional paper bundle stacking completion mark is obtained by detecting the f...

Problems solved by technology

Due to mechanical inertia, the distance between two cartons is too small, the speed of paper feeding is too fast, the insertion stroke of the shovel is too large, the torque of the shovel and the maximum speed of the shovel are limited, and the control system lags behind, etc., the shovel The insertion of the paper holder will fail to achieve the set insertion effect due to the movement lag

[0004] In addition, due to the limitation of the mechanical structure, the installation position of the counting photoelectric switch is sometimes far away from the paper outlet. In addition, when the last carton of the old paper bundle leaves the paper outlet, if the transmission speed of the carton is too fast, the carton will be damaged. Floating due to inertia delays the carton’s descent, and insufficient wind power of the press blower at the paper outlet may cause the shovel to hit the last carton of the old paper bundle due to too fast insertion
