Abstract

The invention discloses a control circuit, method and device of a rewinder, and relates to the technical field of automatic control. The problem of uniformity of the control method of the rewinder issolved. The control method mainly comprises the steps that a motion factor of the rewinder is obtained; the current operation speed is obtained; according to the current speed and the motion factor, the deceleration distance and the inching distance of the rewinder are calculated; the maximum shutdown distance of the rewinder is calculated, and the maximum shutdown distance is the sum of the deceleration distance and the inching distance; whether the target distance is greater than the maximum shutdown distance or not is judged, and the target distance is the distance from the current positionto the target position; if the result is no, a stop signal is generated and sent; if a PLC responds to a shutdown signal and stops the rewinder, inching signals are generated and continuously sent; the target distance is detected; and if the target distance is less than a preset tolerance error, the inching signals stop being sent. The control circuit, method and device of the rewinder are mainlyused in the process of controlling the rewinder.

Description

technical field [0001] This application relates to the technical field of automatic control, in particular to a control circuit, control method and device for a rewinder Background technique [0002] Printing is one of the most important decoration and processing methods for product packaging. Printing plays the role of conveying information and promoting and introducing products. With the continuous improvement of living standards, the quality requirements for printed matter tend to be stricter. Improvement puts forward new requirements. As market demand increases, competition intensifies, and customers' quality requirements continue to increase, resulting in increased difficulty in quality inspection for printing and packaging material manufacturers, increased content, and bottlenecks in efficiency, resulting in reduced production capacity. Relying on human eyes to carry out spot checks of printed matter, human eye detection subjects are quite different, standards are not ...
