[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a band-shaped material such as a metal foil such as an aluminum foil or a copper foil or a plastic film.
Also, the present invention relates to a continuous strip material cutting device and a cutting method for slitting a raw material such as a composite strip material obtained by applying or bonding another substance to the surface of a metal foil or a plastic film, etc. The present invention relates to a band-shaped material cutting device including a material holding device capable of effectively guiding the band-shaped material when slitting the material, and a cutting method using the cutting device.

[0002]

2. Description of the Related Art A cutting point of a cutting device for slitting a strip into a plurality of strips by a plurality of upper round blades fitted and fixed on an upper rotating shaft and a plurality of lower circular blades fitted and fixed on a lower rotating shaft. As a prior art of a material holding device provided in the vicinity to guide a band-shaped material, Japanese Unexamined Utility Model Application Publication No. Sho 62-88523, Japanese Unexamined Utility Model Application Publication No. 1-22611, or Japanese Patent Application Laid-Open No. 7-6841 are known.
There is known a material holding device disclosed in Japanese Patent Application Laid-open No. 1-No.

A material holding device disclosed in Japanese Utility Model Laid-Open Publication No. 62-88523 has an endless belt 25 as shown in FIG. 4, and is rotatable at both ends so that the endless belt 25 rotates in a flat shape. This is an endless belt type material holding device having two sets of rotating rolls 26 supported on the same and a frame 27 supporting the two sets of rotating rolls 26.

A material holding device disclosed in Japanese Utility Model Laid-Open No. 1-261121 is disclosed in Japanese Utility Model Application Laid-Open No. 62-8852.
A driving pulley for adjusting the circulating movement speed of the endless belt to be equal to the moving speed of the slitter plate is added to the endless belt type material holding device as in the case of Japanese Patent Publication No. 3 (2003), and is divided and cut. The circulating movement speed of the endless belt that presses the slitter plate can be made equal to the moving speed of the slitter plate, thereby ensuring that relative slippage occurs between the circulating endless belt and the moving slitter plate. This is a material holding device that prevents lifting of the slitter plate while preventing it, and prevents a pattern or a flaw from being attached to the surface of the slitter plate by an endless belt that prevents lifting.

Next, as shown in FIG. 5, a material holding device disclosed in Japanese Patent Application Laid-Open No. 7-68411 has an upper rotating shaft for the upper and lower rotating shafts 6 and 7, and a lower rotating shaft for the upper rotating shaft. For the shaft, a plurality of receiving rollers 28 each having a length corresponding to the shaft length are provided at the lower portion of the shaft, and presser rings 14 and 15 are provided on the rotating shaft separately from the roller 28 and above and below, respectively. , 15 are fixed by a plurality of receiving rollers 28 and a plate 24 passing therethrough, and by changing the center distance of the plurality of receiving rollers 28,
This is a material holding device using a backup ring in which the distance between the cores 4 and 15 can be changed and the change of the holding amount depending on the plate thickness can be controlled.

[0006]

On the other hand, when slitting a thin band-like material such as a metal foil or a plastic film, for example, as shown in FIG.
Is required to be relatively vertically pushed to secure a predetermined amount of wrap portion T. As a result, the band-like material 24 entering from the entry side is cut at the intersection X on the entry side of the upper round blade 8 and the lower round blade 9, and the cut band-like material 24 is adjacent to the upper round blade 8, 8, or It is necessary to advance to the intersection Y on the exit side while being sandwiched between the lower round blades 9, 9 adjacent to each other, and to be released from between the side surfaces of the adjacent round blades after passing the intersection Y on the exit side. .

However, in this series of flows, irregular tension or compression acts on the thin strip 24, and the strip 24 is warped or twisted.
No. 4 had a problem that harmful defects such as burrs, high edges, and powder dropping occurred. In the vicinity of the intersection Y on the exit side between the upper round blade 8 and the lower round blade 9, the band-shaped material 24 between the side surfaces of the adjacent round blades is rounded as it is sandwiched between the side surfaces of the both round blades. There was also a troublesome problem of being dragged by the rotation of the blade and proceeding in the rotation direction. In order to solve this problem, the intersection X between the upper round blade 8 and the lower round blade 9 on the entry side, that is, from the vicinity of the cutting point by the upper and lower round blades to at least the intersection Y on the exit side, more preferably the upper and lower circles Between the vicinity of the cutting point by the blade and a predetermined position beyond the intersection Y on the exit side, the band-shaped material 24 follows the outer peripheral surface of the upper round blade 8 or the outer peripheral surface of the lower round blade 9 in a uniform state. It is known that it is effective to press the strip 24 against the outer peripheral surface of each round blade by the material pressing means.

[0008] However, the aforementioned Japanese Utility Model Application Laid-Open No. 62-885.
In the case of slitting a thin band-like material such as a metal foil by a slitter provided with a material pressing device as disclosed in JP-A No. 23 or Japanese Utility Model Application Laid-Open No. 1-261121, the endless belt is supported in a flat shape. A pair of front and rear rotating rolls or a pair of front and rear rotating pulleys are provided on both the upper surface side and the lower surface side of the band material over the entire width of the band material to be slit. It is not possible to move the pulley up and down across the strip and adjust the endless belt along the outer peripheral surface of each round blade. It is impossible to press along the range of length on the outer circumferential surface of the slitter, and the slitter provided with such a conventional endless belt type material pressing device Was not suitable for thin strip material slit such as a metal foil.

Further, in a shearing device provided with a material pressing device using a pressing ring as disclosed in Japanese Patent Application Laid-Open No. 7-68411, the belt-shaped material is pressed by a ring made of a rigid body, so that the outer peripheral surface of the ring is used. Is in line contact with the outer peripheral surface of the round blade, and it is impossible to press the band-shaped material against the outer peripheral surface of the round blade within a predetermined range. It could not be used for slits of thin strips such as.

[0010] Further, a pressing ring in which an elastic body such as rubber is lined is formed on the outer peripheral surface of a pressing ring made of a rigid body as disclosed in Japanese Patent Application Laid-Open No. 7-68411 so as to press the band-shaped material. Although a material holding device that performs the above-mentioned operation, a material holding device having such a configuration can be used in a case where the elastic body is pressed against the outer circumferential surface of the round blade so that the elastic body extends along a range of a certain length on the outer circumferential surface of the round blade. The elastic body is compressed in the axial direction, but with the compression in the axial direction, the outer peripheral surface near the compressed portion of the elastic ring also undergoes pulling deformation in the circumferential direction. The harmful tension in the longitudinal direction is applied to, and a favorable result cannot be obtained with respect to a cut edge in cutting a thin strip.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and has been made in consideration of the above-described problems.
