Abstract

PROBLEM TO BE SOLVED: To make a material to be slit move in parallel to a circular cutter and slit the material in a predetermined width by fixing a pressing guide for the material to be slit on a support plate with the horn parts as action shafts and fixing a spring for energizing a support force to one end and fixing a guide roller contacting the material to be slit to the other end. SOLUTION: A DS side guide 2 is fixed to a guide plate 3 with the horn parts of a bifurcated L-shaped stay 16 as action shafts 17 and a spring is fixed to one end of it and a guide roller 4 is fixed to the other end of it. Each guide roller 4 is independently rotated and is being always pressed by the spring to a material to be slit. Since each guide roller 4 independently individually copies and follows the end of the material to be slit without separating therefrom for the changed width of the DS side guide 2 side of the material to be slit, the material to be slit is always pressed to a WS side guide 1 by a uniform force and moved in parallel to a circular cutter 5 and can be slit accurately in a predetermined width.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a side guide device of a slitter for supporting a slit material from a width direction when slitting the slit material.

[0002]

2. Description of the Related Art Generally, in many slitters, the position of a material to be slit in a cutter portion is determined by a side guide device installed before a round blade. Among them, especially in a single-slit slitter, since the product width is determined by the distance between the round blade and the work side (hereinafter, WS) side guide, the parallelism and the mounting position accuracy of the WS side guide with respect to the round blade are extremely high. is important. Here, a configuration of a conventional side guide device is shown in FIG. The side guide device is composed of a fixed WS side guide 1 and a drive side (hereinafter, DS) side guide 2 for pressing a slit-receiving material against the WS side guide 1 from the width direction. The WS side guide 1 has four guide rollers 4 arranged in a straight line on a guide plate 3, and is firmly fixed to a lower holder 6 in a state where the guide rollers 4 are parallel to the round blade 5. One DS side guide 2 connects a guide plate 3 provided with four guide rollers 4 and a jig for fixing a lower holder 6 called a stopper 7 by a spring 8. In the guide setting method of the slit material in the side guide device, first, the slit material is set in the passage L between the WS side guide 1 and the DS side guide 2. Next, the stopper 7 and the main body of the DS side guide 2 are moved in the direction of the WS side guide 1 and pressed against the end face of the slit material, and a certain pressing force is generated against the slit material by the spring action of the spring 8. By fixing the stopper 7 at the position, the slit material is pressed against the WS side guide 1, and the end surface of the slit material on the WS side guide 1 side becomes parallel to the round blade.

[0003] As a material to be slit for the present slit, a material obtained by slitting a side end portion of a master coil is used. Therefore, the linearity of one end in the width direction of the slit material to be slit is poor, and the material width fluctuates. In order to guide such a material to be slit, as shown in FIG.
It is necessary to change the distance between the side guide 1 and the DS side guide 2. As described above, the WS side guide 1 is used as a reference for determining the product width based on the distance from the round blade. Therefore, the material to be slit is set on the WS side guide 1 side so that the side end having good end face accuracy comes. Since the side end of the lower end surface accuracy is set on one DS side guide 2 side, the DS side guide 2 can be flexibly moved just by being pushed by the spring 8 from the stopper 7. The DS side guide 2 of the slit material 9
While following the side end surface, a pressing force against the WS side guide 1 is generated while absorbing width fluctuations.

[0004]

However, even with a side guide device having the above-described functions,
When slitting a slit material having a large width variation, FIG.
As shown in (a), the guide roller 4 of the DS side guide 2 cannot completely follow the end surface variation of the slit material 9 and one of the four guide rollers 4 Contact cannot be made, and the pressing force of the slit material 9 against the WS side guide 1 is reduced only at the guide position of this portion. When the pressing force is reduced, a gap S is generated between the end surface of the slit material 9 on the WS side guide 1 side and the guide roller 4 of the WS side guide 1 as shown in FIG. The slit material 9 is not parallel to the side guide 1, and the slit material 9 is fed obliquely or meandering in the direction of the round blade. As a result, there is a problem that the product width of the slit product varies.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and the DS side is continuously provided even when slitting a slit material having a poor linearity at the width direction end surface and a large width variation. Since all guide rollers of the guide come into contact with the slit material and generate a pressing force against the WS side guide to support it, a slitter side guide that can obtain a high quality slit product with stable plate width accuracy It is intended to provide a device.

[0006]

The gist of the present invention to achieve the above object is to provide a cutting device having a pair of round blades for slitting a slit material, and a reference guide on one side with a slit material passing plate path therebetween. And a slit-type slitter provided with a side guide device for supporting the slit material by providing a slit material pressing guide on the other side, wherein the slit material pressing guide has a double-split form; From the configuration where the corner is installed on the support plate with the working axis, a spring is provided at one end to bias the supporting force to the slit material, and a guide roller is provided at the other end to contact the slit material. A side guide device for a slitter.

[0007]

According to the present invention, since a slit guide has a side guide device which supports the slit target in the width direction and has a flexible followability, which is provided on the slit-target slit passage of the single-slit slitter. The slit material is always pressed against the WS side guide roller with a uniform pressure. Therefore, the slit material having a large width variation runs parallel to the round blade without skewing or meandering, and is accurately slit to a predetermined width.
