DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention is directed to cutting a long plate-like body at least at two locations along a longitudinal direction of the plate-like body along with the transfer of the plate-like body, and the cutting edge has an arc-shaped edge. Thus, the present invention relates to a slitter device for processing such a long plate-like body as a long plate-like body having both side edges directed in the vertical direction and curved in an arc shape.

[0002]

2. Description of the Related Art For example, as in the case of a rain gutter provided along the flow direction of a warped roof, both sides extending in the vertical direction are formed so as to be along an arc of a circle having the same radius. There is a demand for forming a plate-shaped body such as a long metal plate in large quantities.

[0003]

However, in the conventional slitter apparatus, a long plate is attached to the outer circumference of a pair of upper and lower rotary shafts and fed in cooperation with the round blade of the other rotary shaft. In general, since the plate has only a function of feeding the plate in a fixed direction with respect to a cutting means constituted by a round blade which cuts the plate along with the feeding, generally, both sides of the plate are used. It was only possible to make a straight cut edge on the part.

Accordingly, the present invention relates to a slitter apparatus for cutting at least two places in a longitudinal direction of a long plate-like body along with the vertical transfer of the plate-like body.
It is an object of the present invention to perform the cutting so that each cutting edge forms an arc-shaped edge in whole or in part. Another object of the present invention is to make it possible to perform such cutting easily and reliably without complicating the mechanism and without performing complicated control.

[0005]

In order to achieve the above object, according to the first aspect of the present invention, the slitter has the following structure (1) to (4). (1) transfer means for transferring a long plate-like body in a vertical direction;

With reference to a position where the transport direction of the plate-like body and the rotation axis of the upper rotary shaft and the lower rotary shaft are orthogonal to each other, the rotation axis extends in the transport direction before and after the transport of the plate-like body. Tilting means for tilting while gradually changing the tilt angle.

According to this configuration, before and after the transfer of the plate by the transfer means, the inclination angle of the rotation axis with respect to the transfer direction of the plate by the transfer means is gradually changed. For example, both side portions extending in the longitudinal direction of the plate-shaped body such that two cutting edges applied to the plate-shaped body by the cutting means are arc-shaped edges along arcs of a circle having the same radius. Can be disconnected at the same time. By this separation, the plate-shaped body can be formed into a curved shape in plan view, with both side edges along the length direction being arc-shaped edges.

In the invention according to the second aspect, the tilting means in the slitter apparatus according to the first aspect is arranged such that, on the front side of feeding the plate to the cutting means, in the vertical direction of the plate. A rotatable table body provided with guide walls on both side edges and a guide surface for guiding the lower surface of the plate-like body, and a driving means for gradually rotating the table body are provided.

According to this structure, the table is gradually rotated by the driving means before and after the transfer of the plate by the transfer means to change the inclination angle, and The two sides along the length of the plate can be cut off so that the two cut edges applied to the body each have a desired arcuate edge. By this separation,
The plate-like body can be formed into a curved shape in plan view, with both side edges along the length direction being arcuate edges.

The plate-like body shifts the transfer direction of the cutting means with respect to the rotation axis of the upper rotary shaft and the lower rotary shaft in accordance with the rotation of the table body by the guide wall and the guide surface. The plate-like body is smoothly fed into the cutting means while the transfer direction is changed as described above.
