An adaptive adjustment method for the moving speed of the scraper

Abstract

The invention discloses an adaptive adjustment method for the moving speed of a scraper frame, belonging to the technical field of stacking in carton production. In the method, the insertion process of the scraper frame sequentially includes: a start acceleration section, a paper bundle separation section and a deceleration stop section; The start-up acceleration section is when the scraper frame reaches the upper surface of the paper outlet from the position when it is started and inserted; the paper bundle separation section is when the scraper frame reaches the new paper bundle and the old paper bundle from the upper surface of the paper outlet when the separation is completed. The position of the deceleration stop section is the position where the scraper frame reaches the upper surface of the old paper bundle from the position when the new paper bundle and the old paper bundle are separated; in the start-up acceleration section, the scraper frame continues to accelerate and descend; in the paper bundle separation section, The scraper is lowered at the speed of calculation; in the deceleration stop section, the scraper continues to decelerate and descend to a stop; the control method is precise and stable, and the calculation can be automatically optimized according to different mechanical parameters, with high applicability.

Description

technical field [0001] The invention relates to the technical field of stacking in carton production, in particular to a self-adaptive adjustment method for the moving speed 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 method of inserting the scraper frame includes: calcul...

AI Technical Summary

Problems solved by technology

[0005] 1. In order to ensure the insertion effect of the shovel holder, a larger insertion speed and acceleration must be given, which will have a great impact on the mechanical structure and affect the life of the machine

[0006] 2. When the distance between two cartons is very small and the paper feeding speed is very fast, because the insertion time is extremely short, the insertion stroke of the shovel holder is relatively large, and the torque and maximum speed of the shovel holder are limited. Paper holders are prone to problems such as too late to pick up paper, inaccurate stacking of paper bundles, alarm shutdown of the shovel holder, damaged paper, paper jams, and even damage to the mechanical structure, which affects the accuracy of the paper bundle stacking technology of the folder gluer and hinders The speed increase of the folder gluer reduces the output, performance and stability of production, wastes cardboard, and may cause mechanical damage, causing economic losses to production

[0007] 3. Due to the mechanical inertia of the shovel frame, there will be a movement lag. Use the empirical proportional coefficient to speed up the insertion speed. Although the lag can be reduced to a certain extent, if the coefficient is unreasonable, the shovel frame will be inserted ahead of time; and, when different When different types of box gluers are connected to different printing machines, different cartons are produced, different numbers of stacked sheets, and different speeds, the insertion effect of the shovel is different, and the stability of the insertion effect is difficult to control.
