Belted layer winding device and control method

Abstract

The invention discloses a belted layer winding device. The belted layer winding device comprises a belted layer conveying unit, a plastic paper conveying unit and a curling unit. The plastic paper conveying unit unwinds plastic paper through rotation of a plastic paper reel, and the plastic paper is guided to a conveying plate at the rate the same as that of a belted layer. A tension sensor inducts the unwinding tension of the plastic paper, and an electromagnetic clutch arranged on the plastic paper reel is controlled through a tension controller to adjust the tension. The belted layer and the plastic paper laminated on the conveying plate are guided into a tool barrel through the curling unit, the curling device winds the belted layer and the plastic paper into the tool barrel at the linear rate the same as that of a conveying belt after the belted layer and the plastic paper are laminated, and the problems of material bending, drooping, curling and deviating and the like caused by plastic paper tension changes and the inconformity of front and back conveying and curling rates are avoided; and meanwhile, the invention discloses a control method of the belted layer winding device.Signal detection is stable, the problem of possible missing detection is avoided, and the linear velocity of a conveying device is consistent with the linear velocity of the winding device.

Description

technical field [0001] The invention specifically relates to the technical field of tire manufacturing, in particular to a belt winding device and a control method. Background technique [0002] At present, in the tire production process, after the belt layer passes through the conveying device, it enters the curling station, and the belt layer is stored in the tooling bucket. At the same time, there is a layer of plastic paper between each belt layer to ensure that the belt layer does not stick. prison. During the winding process, if the unwinding tension of the plastic paper and the winding speed of the tooling are not properly controlled, it is easy to cause material discounts, sagging, and crooked curls, which will affect the quality of the product. In order to improve product quality more effectively and reduce production costs, a belt winding device is urgently needed. [0003] Chinese patent CN101306581 discloses a tire tread winding method and its system, which spe...

Problems solved by technology

The above technical solution is only applicable to the winding speed of a single sheet, and does not involve the lamination of two materials and the control method of the winding speed, and the control method of the winding speed is to detect the angle of the traction roller through the encoder. Displacement information, the PLC controller can calculate the actual traction speed of the traction roller based on the pulse signal sent by the encoder, and send an analog signal to the winding inverter to adjust the speed of the winding motor, so that the speed of the winding shaft and the traction roller The speed of the reel is consistent and can automatically adjust the speed of the rewinding shaft, but the encoder has the problem of poor reliability of the fault detection mechanism, and the signal detection delay is too long, which may lead to the problem of missed signal detection when the speed is fast
