Abstract

PURPOSE:To enable a rubber strip to be automatically continuously precisely wound on a rotatively driven drum by a method wherein the rubber strip is, in a reciprocative manner, moved on the said drum. CONSTITUTION:A rubber strip W is sent out from a send out means 10 of the rubber strip W provided to an upper part of a column 4 to near one end on a rotatively driven drum 2, i.e., from one end part at a point of time when winding is completed to a central side of the drum, and the first layer of the rubber strip W starts to be wound along a template 26 for an under tread from this position A. While a profile of the rubber strip W wound on the drum 2 is being detected with a gage detection sensor 17 under a state wherein the drum 2 is being rotated at a specific speed, a cross feed drive motor 6 is controlled. While the column 4 is being transferred in parallel with a drum shaft, the profiles of the rubber strip W near a cross fed side and at the central part are formed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rubber strip winding device, and more specifically, it is capable of continuously and accurately winding a rubber strip on a rotary-driving drum while reciprocating the rubber strip. The present invention relates to a rubber strip winding device.

[0002]

2. Description of the Related Art Conventionally, as a method of forming a rubber layer having a predetermined profile by winding a rubber strip on a drum which is rotationally driven and moving in the axial direction of the drum to wind the rubber strip in layers, As shown in FIG. 5, after the operator arbitrarily sets the starting position of the one-layer winding start of the rubber strip W by the feeding device (not shown), the feeding device is moved in one direction while being detected by the detection sensor along the template ( It is moved laterally only in the direction of the arrow).

Therefore, at the end of winding the rubber strip, the feeding device must be stopped by the operator's sensation, and when winding the second layer, the feeding device must be returned to the start position, and there is an undertread. In this case, the under and cap tread templates were exchanged, and winding was performed while moving the feeding device as shown in the figure.

[0004]

However, in the above case, the sensor is located near the right edge with respect to the rubber strip, and the rubber strip having a relatively wide width is diagonally overlapped. The basic problem is
Regarding the preceding part of the winding end of the rubber strip, the winding of the rubber strip will be completed while leaving the sensor detection unknown area, the profile according to the template cannot be obtained, and the volume of the side tread Wa is insufficient. There is a problem that air pockets Q are caused by the above, and quality problems such as tire uniformity, heat resistance, and product failure occur.

Further, at the end of winding the rubber strip, it is necessary to return the feeding device to the starting position in order to wind the second layer in the case of winding with an undertread, by stopping the feeding device with the operator's feeling. There was a problem that productivity was extremely poor. The present invention has been devised in view of such conventional problems, is easy to operate, and even an inexperienced person can easily operate, from the winding start to the winding end of the rubber strip,
It is an object of the present invention to provide a rubber strip winding device that can automatically and accurately wind without requiring manual labor, and that can achieve a uniform shape and reduce product failures. is there.

[0006]

In order to achieve the above-mentioned object, the present invention provides a feeder, in which a column movable on a base in parallel with a drum axis via a traverse feeder is installed, and an upper part of the column is provided. Is provided with a feeding means for feeding the rubber strip to the drum side and a crimping roll means capable of advancing and retracting the rubber strip wound on the drum, and the rubber wound on the drum is provided at the center of the column. A gauge detection sensor that detects the strip and that can move back and forth through the forward / backward drive device and that can move in the axial direction is provided, and the profile of the rubber strip wound on the drum is provided on the rear end side of the gauge detection sensor. The gist of the present invention is to provide a rolling roller and a multistage template that are movable along a rotation axis that is set to be selectable.

[0007]

According to the present invention, the rubber strip is constructed as described above, and the rubber strip is wound from the vicinity of one end side of the desired profile to form the profile of the vicinity of the one end side and the central portion, and then once near the other end side. After interrupting the wrapping with the template, wrap the rubber strip toward the other end in rapid traverse to finish the first wrapping, and then change the position of the multi-stage template and position the gauge sensor with respect to the rubber strip. On the first layer of rubber strip, wind the second layer of rubber strip from the other end side to one end side, form a profile up to the other end side and approximately the center of the center, and then wind Fast-forward the device back to one end, return the position of the gauge sensor to the rubber strip to its original position, and wind it from one end to approximately the center of the central part. By ending the winding without a central portion, in which can be attached accurately winding without requiring human intervention.
