Electric deviation-correcting device

Abstract

The invention discloses an electric deviation-correcting device. The device comprises a front conveying belt, a rear conveying belt, multiple compression rollers, a drum, a case, a visual sensor, a parallel light source, a high-speed counter, an industrial computer and a PLC; the multiple compression rollers, the drum and the case are relatively and fixedly arranged; the case drives the drum to rotate and can also drive the drum and the multiple compression rollers to reciprocate horizontally; the visual sensor can detect the deviation of the edge of a sizing material from a center line under the assistance of the parallel light source and transmits the deviation to the industrial computer in real time; the high-speed counter feeds the position of the rear conveying belt back to the industrial computer in real time; the industrial computer arranges feedback information into a group of data, stores the data accumulatively and meanwhile transmits the data to the PLC; the PLC controls horizontal motion of the case according to the feedback data, so that the center line of the sizing material and the radial center line of the drum coincide to the largest extent in the winding process. The deviation is corrected in the winding process, the distance between a deviation-correcting control point and a winding point is made close, and the possibility that a deviation-correcting system is disturbed is lowered.

Description

technical field [0001] The invention relates to a tire building equipment, in particular to an electric deviation correcting device. Background technique [0002] At present, the centering mechanism used for rubber and plastic equipment is real-time centering: that is, the sensor monitors the offset of the rubber material online, and the real-time drive transmission mechanism places the controlled object to the center of the production line according to the deviation of the sensor. This form of alignment has the following drawbacks: [0003] 1. The response speed of the centering control system is very high, and the hardware cost is not easy to control. [0004] 2. The high-speed response causes high-intensity mechanical shock, which affects the service life of the equipment and the vibration of the system is relatively large. [0005] 3. The sampling frequency of the sensor is too high, and there is no time to effectively filter the signal, resulting in a certain probabil...
