Controlling method for wrapping surface of tire

Abstract

The invention provides a controlling method for wrapping the surface of a tire, comprising the following steps: an industrial personal computer (IPC) analog simulates the deformation of rubber pieces in the process of spire piling and the arrangement distribution situation of the each rubber piece in the surface of the tire to obtain spire pitches among each rubber piece; the IPC computes the virtual circle central coordinate and the radius of a wrapper at each loop of the arc of the surface of the tire, and sends a date to a PLC; the IPC respectively computes the arc of the each loop of the arc section of the surface of the tire, the horizontal coordinate of the each loop of the linear section of the surface of the tire and a corresponding theoretical velocity, to form a data table to be sent to the PLC; the PLC computes the real velocity of the wrapper according to the received data table; and the PLC computes to obtain a track coordinate data of the wrapper corresponding at the each loop and finally controls the wrapper to wrap the surface of the tire. The method realizes analog simulation in the process of wrapping the surface of the tire, adjusts the walk track and the walk velocity of the head of the wrapper immediately, and greatly improves the wrapping quality of the surface of the tire.

[0002] Tread winding has a long history as a tire building technology, but the winding effect is rarely simulated during the winding process of the tire tread, which makes it difficult to control the winding process of the tread and easily affects the quality of the tire

In order to better control the quality of tires, the thickness measuring device on the machine is used more at present to detect the winding thickness. After reaching the thickness, the machine head will move backwards to control the winding of the tire tread, but this The disadvantages of this method are: since the thickness needs to be detected and the walking speed of the machine head is determined according to the thickness, the accuracy and stability of the thickness measuring device are required to be very high; Sometimes and the precision is not enough, making its winding effect unstable, and the machine maintenance rate is also high

At present, for the simulation of the winding effect, generally, the speed of the winding machine can only be adjusted on the x-axis, but cannot be adjusted on the other two coordinate axes. Therefore, the simulation of the winding effect has yet to be developed.
