Description

[Detailed Description of the Invention] The present invention relates to an apparatus for forming marks by making minute cuts in the edges of sheet-like materials such as leather, cloth, rubber sheets, etc.

When clothing and other products are made from leather, for example, cuts are made in the edges to mark the locations of buttons. This hidden mark processing device is equipped with a cutter having upper and lower ends on a pedestal, and a sheet-like object is placed on the pedestal and a cut is made by lowering the cutter. The present invention aims to provide a device for marking the edge of a sheet-like material, in which a vertically movable cutter holder is guided stably and accurately, and the structure is simple.

Embodiments of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, 1 is a base, 2, 2 are two guide rods attached perpendicularly to the base 1, and 3 is a guide lock fixed to the upper ends of the guide rods 2, 2. A cutter holder 4 is slidably inserted into the guide rods 2, 2.
The cutter holder 4 has a convex portion 5 on the front part (left side in Figure 1).
A substantially trapezoidal head 8 having tapered surfaces 6a, 6b on both sides and a flat top surface 7 is formed at the tip of the convex portion 5. A pair of cutters 9a, 9b are attached to the set screws 11 at the lower ends of the tapered surfaces 6a, 6b.
It is fixed through. Preferably tapered surface 6
If grooves 12 and 12 are formed in the grooves a and 6b to fit the cutters 9a and 9b, and the cutters 9a and 9b are fitted into the grooves 12 and 12 and fixed with the setscrews 11, the rattle of the cutters can be avoided. can be eliminated. Tapered blade portions 10a, 10b are formed at the front edges of the cutters 9a, 9b. The upper tips 10'a and 10'b of the blade parts 10a and 10b of the cutters 9a and 9b are attached so that they intersect to form a substantially X-shape (see FIG. 3).

The cutter holder 4 has an operating rod 13 projecting upward that connects the cutters 9a, 9b and the guide rod 2,
2 through bolts 14.
The operating rod 13 is slidably inserted into the guide hole 3a of the guide lock 3. A grip head 15 is fixed to the upper end of the operating rod 13. Even when the cutter holder 4 has reached its lowering end, the operating rod 13 remains in the position of the guide lock 3.
The length is such that it protrudes an appropriate length above the. A locking groove 16 is formed in the lower end of the operating rod 13 at a position appropriately spaced from the cutter holder 4. A hole 24 communicating with the guide hole 3a is formed in the guide lock 3, and a ball 17 and a spring 18 for biasing the ball 17 toward the operating rod 13 are inserted into the hole 24. The ball 17 is locked in the locking groove 16 to prevent the cutter holder 4 from falling naturally.

The base 1 has four dice 19a, 19b,
19c and 19d are fixed, and X
Cutter receiving grooves 20 are formed in a shape that crosses each other. Reference numeral 21 denotes an L-shaped positioning plate, which is fixed to the base 1 by inserting screws 23 into long holes 22 formed at its bottom.

Next, the effect will be explained. The cutter holder 4 is raised by holding the grip head 15 and pulling up the operating rod 13. At the rising end, the ball 17 engages with the locking groove 16 to prevent the cutter holder 4 from falling naturally. The sheet-like materials S to be marked are stacked with their edges in contact with the positioning plate 21. Next, by holding the grip head 15 and pressing it downward, the cutter holder 4 is lowered via the operating rod 13, and the cutters 9a, 9 are lowered.
The edges of the sheet-like material S are cut by the blade portions 10a and 10b of b, and a triangular mark is applied.
Even when the cutter holder 4 reaches the lower end, the operating rod 13 protrudes from the guide lock 3 by an appropriate length, so there is no risk of fingers being caught between the guide lock 3 and the grip head 15, making it safe and easy to grip and operate. Good.

As described above, according to the present invention, the guide block is fixed to the upper end of the guide rod, the operating rod is slidably inserted into the guide hole of the guide block, and the lower end of the operating rod is connected to the cutter guide rod. Since the operating rod is fixed to the cutter holder which is slidably inserted into the guide rod in between, the operating rod descends without wobbling.
The cutter holder can be accurately lowered while always being held horizontally without causing sideways movement or inclination, and therefore the vertical movement of the cutter holder is always performed smoothly and accurately, and the configuration is simple. Can be manufactured cheaply.

Furthermore, since the operating rod is positioned closer to the cutter of the cutter holder, the stability of the cutter holder is improved and the cutter descends without wobbling.

Furthermore, when the cutter holder reaches its lower end, the operating rod protrudes from the guide block by an appropriate length, so there is no risk of fingers being caught between the guide block and the grip head, making it safe, and the grip head is easy to grip and has good operability.
