DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for positioning a splice position when changing the angle of a strip material, and more particularly, to detecting an end face detector of a strip material when changing the splice angle of the strip material. The present invention relates to a method and an apparatus for positioning a splice position when changing the angle of a strip-shaped material, which can maintain a constant splice state at any splice angle while keeping a constant distance from a surface.

2. Description of the Related Art Conventionally, when a belt-like material such as a tire constituent material is spliced and continuously wound, a rear end of the preceding belt-like material and a front end of the latter belt-like material are abutted with each other.
The terminals are joined together by a splicer device ,
Alternatively, they are bonded together (hereinafter, referred to as splices) . In this case, the end portion of the strip material is oriented in the longitudinal direction of the strip material.
Is cut at an inclination angle α (bias) with respect to
Seaming of splice also strip material of the splicing device
It is moved in accordance with the angle (hereinafter, referred to as a splice angle) .

[0003]

When the end portions of the strip material are spliced, there are various splice angles at the end portions of the strip material, and it is necessary to change the splice angle of the splicer device each time. In this case, as shown in FIG. 5, when the turning center O of the splicer device (not shown) is arranged at the center of the width H of the strip material W, in the case of the strip material Wa having a small splice angle α, It is not necessary to feed the strip material Wa so much with respect to the splice position, but in the case of the strip material Wb having a large splice angle α, the feeding amount L of the strip material Wb
In such a case, there is a problem that the tip of the strip-shaped material is deformed or displaced, so that accurate splice (joining or bonding) cannot be performed.

[0004] When joining the end portions of the strip-shaped material W, the end portion of the strip-shaped material W conveyed by the conveyor 1 is detected by an end face detector 2 such as a photoelectric tube. After detecting the terminal portion of the band-shaped material W, the splicer is rotated by turning a splicer device (not shown) to the splice position. However, when the angle of the splicer device is changed, it is desirable to dispose the end face detector 2 at the turning center O of the splicer device as shown in FIG. As shown in FIG. 7, the detection of the splice position becomes impossible due to the displacement of the material W, and the detection becomes unstable, and there is a problem that the splice accuracy cannot be improved.

The present invention has been devised in view of such a conventional problem. When the splice angle of a strip material is changed, the fluctuation of the distance between the end face detector of the strip material and the splice point is minimized. It is another object of the present invention to provide a method and an apparatus for positioning a splice position at the time of changing the angle of a strip-shaped material, which can maintain a constant splice state at any splice angle and can reduce fluctuations in splice accuracy.

[0006]

Means for Solving the Problems] In this invention to achieve the above object, setting the position Spline service frames corresponding the turning center of the splicing device to the edge portion of the strip material
A first guide member is provided on the splicer frame, and the first guide member is slid along the first guide member.
A movable slide member is provided, and the slide member

The end face detector is slidably disposed along a second guide member provided at a fixed distance inside, and the end face detector is kept at a fixed distance from a splicer traveling reference line when the splicer device turns. The gist of the present invention is that the user moves with.

[0007]

The present invention is constructed as described above, and when the splice angle of the strip material is changed, the turning center provided at the position corresponding to the edge of the strip material in accordance with the splice angle is used as a fulcrum to support the splicer device. When the frame is turned by a predetermined angle, with the change of the angle of the frame of the splicer device, the end face detector of the band-shaped material connected to this frame via the guide device moves a fixed distance from the splicer traveling reference line at each angle. By performing the positioning while moving while holding the splice, it is possible to reduce the fluctuation of the splice accuracy while keeping the splice state constant at any splice angle, and to perform the splice with high accuracy.

Embodiments of the present invention will be described below with reference to the accompanying drawings. The same components as those of the conventional example are denoted by the same reference numerals, and description thereof will be omitted. FIG. 1 is a schematic configuration diagram of a splicing position locating device embodying the present invention. A swivelable splicer frame 3 provided with a splicer device (not shown) is arranged so as to sandwich a transport conveyor 1 for a band-shaped material W. This conveyor 1

When the end surface detector 2 is turned by a predetermined angle corresponding to the above, the end surface detector 2 moves on the XX line by a predetermined distance S, and always detects the end surface on the splice line of the belt-shaped material W.

That is, by moving the position P ₁₇ of the end face detector 2 at the position where the splice angle α is 17 ° by a distance S,
_'To the position P ₃₀ of the end face detector 2 splice angle α is in the position of 30 ° the distance S only by moving P _{30' 17} when a to, a point B returns a difference 13 ° splice angle α , And let T be the line connecting point B and P _{17 ′} ,
