Abstract

PURPOSE:To provide a service guide in a tire forming machine which can guide to a get position of a forming drum under an always stabilized state by a method wherein a tip edge part of a low angle strip material containing a steel cord is held by attraction by magnetic force. CONSTITUTION:A horizontal receiving roll 2 is formed so that its length becomes successively shorter toward an tip edge part 1a side of a strip material 1. Further, a vertical guide roll 4 disposed in upright is supported with a guide plate 5 capable of sliding in a width direction of the strip material 1 via a bracket 6. The vertical guide roll 4 is composed of a magnet made roll. The vertical guide roll 4 is freely rotatively supported with a roll support component 10 of a U-shaped section at a tip part of an L-shaped bracket 6 fixed onto the guide plate 5 via a bearing 11 and a shaft 12.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a servicer guide in a tire forming machine, and more particularly to a tire forming machine for guiding a low-angle strip-shaped material containing a steel cord, for example, a steel finishing, a front edge portion of a belt or the like. It is about the servicer guide.

[0002]

2. Description of the Related Art Conventionally, as a structure of a servicer guide in a tire molding machine, for example, a plurality of horizontally arranged horizontal receiving rolls for guiding a tip end portion of a strip-shaped material containing a steel cord to a tire molding drum side, The horizontal receiving roll is configured to be guided by a side face, that is, a vertical guide roll standing upright on the leading edge portion side of the strip-shaped material at a predetermined interval.

By the way, in the conventional vertical guide roll, since a simple free roller is used, there is a problem that the guide position at the tip of the low-angle strip material with steel cord is not effective and the get position becomes unstable with respect to the tire forming drum. there were. The present invention has been devised by focusing on such a conventional problem, and by attracting and holding the tip edge portion of a steel cord-containing low-angle band-shaped material by magnetic force, the molding drum can be always obtained in a stable state. An object of the present invention is to provide a servicer guide in a tire building machine that can guide the position.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a steel cord-containing band-shaped material with a tip portion,
A tire forming machine in which a plurality of horizontally arranged horizontal receiving rolls for guiding to the tire forming drum side and vertical guide rolls standing upright on a side surface of the horizontal receiving rolls at a predetermined interval The gist is that the vertical guide roll of the servicer guide is constituted by a magnet roll.

[0005]

The present invention is configured as described above and is a magnet roll used as a vertical guide roll, which is formed by adsorbing the leading edge portion of the steel cord-containing strip-shaped material and guiding it on the tangent line of the roll. This makes it possible to always obtain an accurate position with respect to the drum get position.

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a plan view of a servicer guide in a tire molding machine embodying the present invention, FIG. 2 is a front view thereof, FIG. 3 is a side view of FIG. 2, and 1 is a steel cord-containing low-angle strip-shaped material (for example, (Steel finishing, belt, etc.), 2 is a plurality of horizontal receiving rolls for horizontally supporting the tip edge portion 1a of the strip-shaped material 1 on the tire forming drum 3 side, and 4 is a predetermined distance on the side of the horizontal receiving roll 2. Shows a vertical guide roll standing upright, and the horizontal receiving roll 2 is a leading edge portion 1a of the strip-shaped material 1.
The vertical guide rolls 4 which are formed so that the length thereof becomes shorter toward the side, and which are provided upright, have a width H of the strip-shaped material 1.
It is supported via a bracket 6 on a guide plate 5 that can slide in any direction.

The guide plate 5 is slidably supported by a guide rod 7 arranged in parallel with the horizontal receiving roll 2 via a slide bearing 8, and the guide plate 5 is also provided.
Is configured so that the position can be adjusted in the width direction of the strip-shaped material 1 by the guide screw 9. The vertical guide roll 4 is composed of a magnet roll, and the vertical guide roll 4 is an L-shaped bracket 6 fixed on the guide plate 5 as shown in FIGS. 2 and 3.
A roll supporting member 10 having a U-shaped cross section is rotatably supported at the tip end thereof by means of a bearing 11 and a shaft 12. Since the vertical guide roll 4 is composed of a magnet, it is not biased to one side of the roll support member 10 due to its magnetic force, and the bearing 11 and the vertical guide roll 4 are arranged so as to rotate smoothly. It is preferable to interpose a spacer 13 made of a non-magnetic material such as a resin material. Also, the bearing 11 and the shaft 1
It is desirable that 2 is also a non-magnetic material.

In order to always guide the strip-shaped material 1 in the tangential direction of the vertical guide roll 4, the vertical guide roll 4
It is desirable to form the guide groove 14 of the strip-shaped material 1 on the peripheral surface of the.
As shown in FIG. 4, a hollow cylindrical vertical guide roll 4 composed of a magnet is vertically divided into two parts,
A washer 15 which is a non-magnetic material is interposed therebetween, and a shaft 12 which is a non-magnetic material is inserted therethrough.

The present invention is configured as described above and is a magnet roll used as the vertical guide roll 4, which can attract and hold the leading edge portion 1a of the steel cord-containing strip material 1 in the tangential direction of the roll. Therefore, an accurate get can always be obtained with respect to the get position of the forming drum 3.

[0010]

As described above, according to the present invention, a plurality of horizontally arranged horizontal receiving rolls for guiding the front end of the steel cord-containing strip-shaped material to the tire forming drum side, and the horizontal receiving rolls In a servicer guide in a tire molding machine that is guided by a vertical guide roll that is erected at a predetermined interval on the side surface, the vertical guide roll is composed of a magnet roll, so a magnet roll used as a vertical guide roll, By sucking the leading edge portion of the strip-shaped material containing the steel cord and guiding it on the tangent line of the roll, there is an effect that it is possible to always perform an accurate get at the get position of the forming drum.
