Method and system for automatic edge alignment of online corrugated cardboard line base paper frame

Abstract

The invention discloses a method for automatic edge alignment of an online corrugated board line body paper frame. The method specifically comprises the following steps that (1) a base is arranged, and the body paper frame is arranged on the base; (2) a set of mechanical arms is arranged, body paper tubes and first displacement sensors are arranged on the mechanical arms; (3) second displacement sensors are arranged; (4) a hydraulic driving device is arranged; (5) a control system is arranged; (6) a power source is powered on to be in a work state, the two sets of displacement sensors are arranged on the body paper frame and detect the distance information of the end faces of the two body paper tubes and the corresponding first displacement sensors on the body paper frame and the distance information of the mechanical arms and the corresponding second displacement sensors respectively, the control system receives the distance information of the two sets of displacement sensors, the distance deviation of the end faces of the adjacent body paper tube is calculated and is converted into a control instruction to be sent to the hydraulic driving device, motion control over the mechanical arms is achieved, and the precise and automatic alignment of the end faces of the two body paper tubes is achieved. The invention further discloses an alignment system for achieving the method.

Description

technical field [0001] The present invention relates to automatic control technology, in particular to an on-line corrugated cardboard line base paper frame automatic automatic edge-alignment function, which adopts sensing technology, data processing technology and motion control technology, and is applied to a corrugated cardboard production line to meet the automatic edge alignment function of a round paper tube on a base paper frame. Alignment systems and methods. Background technique [0002] The production of corrugated paper is the basic material of the traditional packaging industry. At present, the automation of domestic production lines is still low, and many production processes still rely on manual observation to control the quality.

Problems solved by technology

[0002] The production of corrugated paper is the basic material of the traditional packaging industry. At present, the automation of domestic production lines is still low, and many production processes still rely on manual observation to control the quality. Taking the feeding of raw paper racks as an example, each roll of raw paper tubes is installed on the raw paper rack. In the future, it will rely on manual visual inspection to see if it is neat, and then adjust the hydraulic device for fine-tuning through manual buttons, and visual evaluation by adding scales, etc. In the entire domestic corrugated paper production line, almost 99% of the corrugated paper production lines use manual visual inspection. The degree of automation is extremely low, resulting in a large consumption of human resources, slow edge-to-edge speed, and high production costs

[0003] At present, the E+L company in Germany has adopted the principle of measuring light curtain for automatic edge alignment, but its cost is too high, and the installation is complicated, so it is difficult to use universally. There are also many domestic companies conducting research in the field of automatic edge alignment of base paper, such as Shanghai Some packaging companies propose to use laser sensors combined with guide rails to scan the edge of the original paper tube for automatic edge alignment, which is only theoretically feasible. In the actual installation and debugging process, it is found that this method has low precision and poor stability. not available at all

Due to the limitation of actual production conditions, factors such as harsh environment, high temperature, high humidity, high noise, high dust, and interference in the corrugated paper production line often cause frequent abnormalities in the existing high-precision automatic alignment systems at home and abroad, which are difficult to sustain ,Stable job
