Bus-based tension-free rubber rolling control system and control method thereof

Abstract

The invention provides a bus-based tension-free rubber rolling control system and a control method thereof, and relates to the field of industrial automated control. The bus-based tension-free rubber rolling control system comprises a PLC system, an operation panel, two laser measuring sensors and two vector frequency converters, wherein the PLC system comprises a CPU module, a DC 24V power module, a real-time industrial Ethernet bus and an analog input module. In the control method, speed of a conveying line, a working position of a single ring and speed of a rolling wheel in a rubber rolling process are monitored and controlled in real time by the control system. The control method comprises the following steps: setting the working position of the single ring and a rolling mode; acquiring the position of the single ring, the rolling diameter of the rolling wheel and the state of the vector frequency converters; processing control information of the rolling wheel; outputting the control value of the rolling wheel; and displaying monitoring. By the control system and the control method thereof, rubber products cannot be pulled in a rubber product rolling process, the quality of the products is guaranteed effectively, and the system is compact in mounting, large in adaptation range, stable in work and accurate in control.

Description

Technical field [0001] The invention relates to the field of industrial automation control, in particular to a rubber winding control system and a control method thereof. Background technique [0002] At present, in many rubber winding control systems, due to the relatively fine process requirements of the rubber production process, the commonly used winding methods and the main problems are as follows: [0003] Goniometer swing frame detection and ultrasonic roll diameter mode, such as figure 1 As shown, the number 1 in the figure is a rubber belt, 2 is a counterweight tension adjustment nut, 3 is a swing frame, 4 is a reel, 5 is an ultrasonic measuring sensor I, and 6 is a transmission. Due to the characteristics of the installation method and the structure itself, it works The swing angle stroke and the change signal slope, as well as the inertia effect of the mechanical swing and the balance of the counterweight, the free roller on the swing frame and the film will remain in co...

Problems solved by technology

When the motor speed decreases, the force torque decreases, and the slip becomes larger, causing the tail winding to fail to work properly when the roll diameter increases, especially for wide-format films.
