Abstract

PURPOSE:To absorb a difference in rotational speeds being produced in a contact part with a long material at each part as well as to stabilize material revolution and directability by installing a roller type guide arranged with plural pieces of bearings on a single shaft, in a winder for the long material. CONSTITUTION:A guide 5 is provided with a bearing 7 attached to a side plate 4, a shaft 8 installed in this bearing 7, plural numbers of bearings 9 attached in line with this shaft 8, and a flange 10 installed at both ends of the bearings 9. Since each bearing 9 is rotatable with its own rotational speed, it is followable in accord with speed of a long material 1 contacting with respective bearings 9. Consequently, a difference between peripheral speed of the long material 1 and rotational speed of the guide 5 is absorbed, floating and falling of the long material 1 is prevented from occurring, thus the long material 1 is smoothly wound up.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a winding machine for a long material.

[Conventional technology]

FIG. 1 is a partial cross-sectional view showing a conventional winding machine for long materials (strip materials) using an integrated rotating type or fixed type guide.
In the figure, (1) is a long material, (2) is a driving pinch roll that feeds the long material (1), (3) is a material bending roll that bends the fed long material (1) into a curved shape, ( 4) is a side plate that holds the rolled-up long material (1) from both sides; (5)
are guides arranged radially from the center inside the side plate (4), and integrally rotating or fixed guides are used.

(6) The rotatable material receiver for receiving the rolled-up long material (1) is a roll.

In the long material winding machine configured as above,
The long material (1) sent from the previous process.

The material is sandwiched between the drive pinch rolls (2) and sent further ahead, bent into a curved shape by the material bending rolls (3), and the material receiver is wound up into a coil shape on the rolls (6). In order to align the edges, the edges are held down by an integrally rotating or fixed guide (5) and rotated in the direction of arrow R to form aligned windings.

[Problem to be solved by the invention]

Conventional long material winding machines using integrally rotating or fixed guides have the above-mentioned configuration. The elongated material (1) is pressed down from both sides according to the width of the elongated material (1) and rolled up while the edge of the elongated material (1) is in contact with the integrally rotating or fixed guide (5).

At this time, since the integrally rotating or fixed guide (5) is an integral piece, due to uneven edges of the long material (1),
When the coil diameter becomes larger, an integrally rotating or fixed guide (5) is used at the contact part on the inner diameter side B part and the outer diameter side A part.
There is a difference in the rotational speed (speed) between the rolled material (1) and the long material (1), and the material receiver may float up from the roll (6) and fall off, or ) was not rolled up after the material bending roll (3), causing problems such as bulging in a curved state.

This invention was made to solve the above-mentioned problems.It has a strong, easy-to-replace, and versatile guide that is inexpensive, can absorb the difference in circumferential speed of a long material at each part, and can be used smoothly. The purpose of the present invention is to obtain a winding machine for long materials that can be wound into long materials.

[Means to solve the problem]

The long material winding machine of the present invention includes a driving pinch roll for feeding the long material, a material bending roll for bending the fed long material into a curved shape, and a material holding roll for holding the wound long material. A long material winding machine consisting of side plates arranged on both sides, a roller type guide arranged radially from the center on the side plates, and a rotatable material receiver that receives one roll of the long material and a roll. In this, a plurality of bearings are installed over the entire range of the long material edge contact portion of the roller type guide, so that when the long material edge portions contact, the difference in circumferential speed of the long material is absorbed. be.

That is, the present invention includes a roller type guide in which a plurality of bearings are arranged on one axis, and when there is a difference in the number of rotations (speed) with the long material on the -axis, the difference can be absorbed, The bearing used as a bearing is exposed on the surface of the roller type guide, and the roller type guide, which can rotate in parts on the -axis, is arranged radially from the center of the coil for winding a long material.

[For production]

The long material winding machine of the present invention is equipped with a roller type guide in which a plurality of bearings are arranged on one axis. The difference in rotational speed (speed) that occurs at the contact portion with the long material is absorbed, and the rotational speed and directionality of the material are stabilized.

〔Example〕

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. The basic structure of the winding machine for a long material according to the embodiment is shown in the same manner as in FIG.

FIG. 2 is a front view showing a part of the guide (5) in FIG. 1 in cross section. In FIG. It is a roller type guide consisting of a shaft (8) mounted on a shaft (8), a plurality of bearings (9) mounted in parallel on this shaft (8), and flanges (10) provided at both ends of this bearing (9). 1 person The number of rotations (speed) that each bearing (9) matches the peripheral speed of the long material (1) in contact with that position
It is designed to rotate.

In the long material winding machine configured as above,
By using a roller type guide as the guide (5), each bearing (9) can rotate at its own rotational speed, so it can follow the speed of the long material (1) that comes into contact with each bearing (9). Therefore, the difference between the rotational speed of the long material (1) and the rotational speed of the guide (5) is absorbed, and the long material (
1) is prevented from floating or falling off, and the long material (1) is wound up smoothly.

In the above embodiment, a winder for winding strips is shown as a long material winding machine, but the present invention can also be applied to other types of long material winding machines.

〔Effect of the invention〕

As described above, according to the present invention, since the roller type guide equipped with a plurality of bearings is used, the number of revolutions (speed) is adjusted according to the speed of the material passing over the roller type guide.
It can be used even when different operations are required, the speed and directionality of the material are stable, the strength is improved, and the effect is great at low cost.
