Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a grooving device for a long material, which includes a conveying device equipped with a cutter and a locking guide piece, and is capable of correctly grooving a long material.

For example, decorative edges a used for building baseboards, wainscoting, etc., can be made by forming a rectangular board with a synthetic resin sheet (e.g., PVC sheet) attached to it, as shown in Figure 3a, into strips as shown in the figure. After cutting it into a long base material, mark the same figure C on the back side.
As shown in the figure, a groove C is formed in the longitudinal direction, and a backing material d is pasted between the groove C and the groove C as shown in d in the same figure.
It is formed by bending the base material along the side edges of the base material (as shown in the figure e), but in order to obtain a decorative edge a without unevenness or warping, the groove C should be parallel to the side edge of the base material and It is necessary to process it correctly according to a certain method.

The purpose of the apparatus of the present invention is to provide a grooving apparatus for a long material that can be used for grooving a long material such as a decorative edge a, and one embodiment thereof will be described below with reference to the drawings.

In the figure, the device 1 of the present invention has a conveyor 2 equipped with a cutter 3 and a locking guide piece 4, and the conveyor 2 is further provided with a presser roller 5 and a guide piece 6.

In this embodiment, the conveying device 2 is constructed using a roller conveyor in which drivable rollers 7 are arranged side by side, and a pedestal 10 whose upper surface is flush with the side frame 9 is provided adjacent to the conveyor.

The pedestal 10 is provided with the guide piece 6 having an abutting surface 11 extending along the conveying direction of the conveying device 2 in close proximity to the upper surface of the roller 7 over almost its entire length, and supports 12 at both ends of the pedestal 10 are provided with , the presser roller 5 extending above the conveying device 2 is rotatably mounted.

The presser roller 5 can be raised and lowered by a handle 13 and is made of an elastic material such as soft rubber.

A cutter support 15 is provided at the center of the pedestal 10, and a cutter head 17 is attached to it by a slide shaft 16 at its upper end.

The cutter head 17 engages with the screw shaft 19 and the handle 200
Rampant and creeping due to rotation.

The cutter blade 17 supports a cutter 3 having a rotary blade 1B rotated by a drive machine, and the guide piece 6 has the above-mentioned engagement plate close to the cutter 3 and downstream in the conveying direction of the conveying device 2. A stop guide piece 4 is provided.

The locking guide piece 4 has an elongated hole 2 extending in the elongated direction at its base.
2, it can be fixed to the guide piece 6, and its tip has a sharp tip and an inner surface f, which can be inserted into the V-shaped groove g in this embodiment.
has a blade-shaped portion 23 that comes into contact with the inner wall W of the groove g on the side facing the guide piece 6 and engages with the groove g.

However, in the apparatus 1 of the present invention, the long material 24, such as the base material of the decorative edge a, is carried in with one side edge slidingly in contact with the contact surface 11 of the guide piece 6, and the presser roller 5 is lowered. , the long material 24 is pinched between the rollers 7 of the conveying device 2 to prevent it from floating, and the cutter 3 is rotated to carve grooves g such as ■ grooves. The blade-shaped portion 2 of the guide piece 4 locks the inner wall W of the groove g at the tip.
3 to guide the engagement, it is possible to automatically form grooves g parallel to the side edges and of a constant height without causing any deviation.

Note that the degree of pinching of the elongated material 24 can be adjusted by the bundle 13, and the lateral position of the groove g can be changed by the bundle 20.

As shown in the diagram above, the device of the present invention can process a long material by pressing it with a pressure roller and guiding it with a guide piece and a locking guide piece. In particular, since the locking guide piece engages with a groove, it can process a long piece of material. By engaging the locking guide piece at the tip of the material, it is possible to form grooves parallel to the side edges of the elongated material and having a constant depth without causing any displacement. Suitable for use in vines.
