本考案は製鉄プロセスラインの帯板や紙、ビニ
ール等の帯板の切断装置に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for cutting strips of steel manufacturing process lines and strips of paper, vinyl, and the like.

Conventionally, as shown in FIG. 4, the drums 2 and 3 are each provided with one convex blade 4 and one concave blade 5, and the strip plate 1 is cut by the concave blade 5 and the concave blade 4. Band plate 1
It was designed to rotate in sync with the traveling speed of the vehicle.

However, with the conventional method, if sufficient tension is applied to the strip, smooth cutting can be performed without any problems, but if the tension acting on the strip is small (for example, δT = 1 to 3 Kg/mm 2 ) had the disadvantage that troubles such as poor cutting were likely to occur.
Further, as shown in the explanatory diagram of FIG. 3, when the tension of the strip plate becomes small, the clearance amount C that can be cut becomes narrower, so there is a drawback that the conditions for cutting are further reduced.
本考案は低張力時に切断不良となりやすいとい

The present invention focuses on the point that in order to solve the conventional drawback that poor cutting is likely to occur when the tension is low, it is sufficient to locally generate large tension at the cut part of the strip even when the tension is low. This is a combination of three convex and convex blades each so that tension is generated on the strip within the cutting blade, and when cutting with the central blade, the front and rear blades are used to hold the strip so that tension is generated. This feature is characterized in that it is retained.

Since the present invention is constructed as described above, when cutting the strip while restraining it so that it does not slip,
Since tension is generated in the strip, the strip can be easily cut.

Hereinafter, the present invention will be specifically explained based on the embodiments shown in FIGS. 1 and 2. In this embodiment, the drums 2 and 3 have three convex blades 4, 4A, 4B,
4C and three concave blades 5, 5A, 5B, and 5C are provided, and the strip plate 1 is sandwiched between these blades. When cutting, as shown in Fig. 2, when the strip 1 is cut with three sets of concave and convex blades 4 and 5, the first convex blade 4
The band plate 1 is sandwiched between the concave blade 5C and the concave blade 5C, but the band plate is not cut in this state because the tension of the band plate is small. Next, when the drums 2 and 3 rotate a little more, the central convex blade 4B and concave blade 5B bite the strip 1, but even here, the tension of the strip is still insufficient. This is because tension is generated only between the convex blade 4C and the concave blade 5C and between the convex blade 4B and the concave blade 5B.
次にドラム２，３がもう少し回転すると、３組
の凹凸刃４，５が全て帯板１をかむことになる。
すると、凸刃４Ｃ、凹刃５Ｃと凸刃４Ｂ、凹刃５
Ｂ間および凸刃４Ｂ、凹刃５Ｂと凸刃４Ａ、凹刃
５Ａ間で帯板１は拘束されるので凸刃４の押し込
み量分相当だけ帯板が伸び、必然的に刃間で張力
が発生して帯板１は中央の凸刃４Ｂ、凹刃５Ｂ間
で切断されることになる。 Next, when the drums 2 and 3 rotate a little more, all three sets of uneven blades 4 and 5 bite the strip plate 1.
Then, convex blade 4C, concave blade 5C, convex blade 4B, concave blade 5
Since the strip plate 1 is restrained between B and between the convex blade 4B, the concave blade 5B and the convex blade 4A, and the concave blade 5A, the strip plate stretches by the amount of push by the convex blade 4, and tension is inevitably created between the blades. As a result, the strip plate 1 is cut between the central convex blade 4B and the concave blade 5B.
以上具体的に説明した様に、本考案においては

ため、クリアランス量Ｃも大きくとる事ができ、
クリアランスや、刃の管理が容易となり、操業上
大いに有効である。
As specifically explained above, in this invention, three sets of uneven blades are provided on the drum, and the strip plate is restrained between these blades, so that tension is generated in the strip plate by the amount of push of the blades. This makes it possible to easily cut strips even when running under low tension. Also, since the cutting is under high tension, a large amount of clearance C can be achieved.
Clearance and blade management become easier, which is very effective for operations.
