Description

  The present invention relates to a cutter device that cuts a sheet-like floor material such as a carpet and a resin-made sheet-like floor material into a length whose end face is along the lower end of a wall surface.

When laying and constructing sheet-like flooring on the floor of the house, which is the laying surface, lay the sheet-like flooring toward the opposite wall from one side of the wall, and go over the remaining part of the sheet-like flooring The cutting edge is made to coincide with the corner between the lower end (baseboard, etc.) of the opposite wall and the floor surface.
By the way, in the case of a sheet-like floor material that is thin and easy to bend, as shown in FIG. 3, the surplus portion of the sheet-like floor material 100 is bent along the corner 400 between the lower end 200 of the wall and the floor surface 300. By bending the L-shaped bent portion with a cutter 500, the cutting edge is made to coincide with the corner between the lower end of the opposite wall and the floor surface (see, for example, Patent Document 1). ).

  However, the sheet-like flooring includes a resin-made multilayer structure or a hard resin. In the case of a sheet-like flooring made of such a multilayer structure or a hard resin, the sheet-like flooring is used. If an attempt is made to bend in an L shape as described above, delamination, cracks, or the like may occur at the bent portion, and the cut edge may not match the corner between the lower end of the wall and the floor surface in some cases.

  Therefore, as a method of cutting such a sheet-like floor material made of a multilayer structure or a hard resin in accordance with the corner between the lower end of the wall and the floor surface, there is a method using a cutter device 600 as shown in FIGS. Already done.

The cutter device 600 has two molding rollers 610 having convex curved surfaces. As shown in FIG. 5, these molding rollers 610 are provided between the lower end 200 of the wall and the floor surface 300. The lower end 200 of the wall is formed while being molded so as to substantially follow the curved surface of the shaping roller 610 while sandwiching the surplus portion of the sheet-like flooring 100 laid from 300 to the lower end 200 of the wall and a part of the vicinity thereof. By rolling along, the sheet-like flooring 100 is cut by the cutter 620 provided between the two molding rollers 610.

  That is, according to the cutter device 600, the shaping roller 610 has an optimal curved shape in accordance with the material of the sheet-like material 100, and the sheet-like material 100 has a curved shape that does not cause delamination, cracks, or the like. The curved material 100 is rolled while maintaining the shape material 100, and the curved portion (not shown) molded by the molding roller 610 is formed between the floor surface 300 and the lower end 200 of the wall with a cutter, and the curved portion is moved by the cutter. Since it cuts in the direction of the ridgeline, even in the case of a sheet-like floor material made of a resin multi-layer structure or a sheet-like floor material made of a hard resin, the cutting edge is good without causing delamination or cracking, etc. It can be cut to coincide with the corner between the lower end of the wall and the floor.

  However, the cutter device 600 has the following problems when, for example, a sheet-like flooring material is short in size, such as a tile carpet, and a plurality of sheets are connected in the rolling direction of the molding roller. May occur.

  That is, when a plurality of sheet-like floor materials are connected and laid in the rolling direction of the molding roller 610, the molding roller 610 is rolled, and the molding roller on the front side in the rolling direction (hereinafter referred to as “front roller”). ”) Moves over the joint between the sheet-like flooring and the sheet-like flooring and moves to the sheet-like flooring located on the front side in the sheet rolling direction (hereinafter referred to as“ front-side sheet-like flooring ”), and In the section from rolling until the cutter reaches the seam side end surface of the front sheet-like flooring, the front sheet-like flooring is from the portion sandwiched between the floor surface by the front roller and the lower end of the wall to the front sheet. Since the portion is not pressed from above at the seam side edge of the sheet-like floor material, the vicinity of the seam portion of the sheet-like floor material jumps up from the wall depending on the material and the layer structure of the sheet-like floor material. And if a cutter reaches the joint edge part of a front sheet-like flooring in this springing-up state, a cutting position will shift | deviate and the cutting edge of a sheet-like flooring will not follow a corner well. Therefore, it is necessary to press the end of the sheet-like floor material so that the cutter reaches the seam side end surface of the sheet-like floor material and accurately hits the cutting position.
