Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cutting device, and more particularly to a cutting device capable of adjusting a cutting pressure in a cutting plotter.

[0002]

2. Description of the Related Art FIGS. 3A, 3B and 4 are views showing a main part of a cutter pressure adjusting mechanism in a conventional cutting plotter. FIG. 3A is a front view.
(B) is a side view and FIG. 4 is a plan view.

Referring to FIGS. 3 (A), 3 (B) and 4, a cutter pressure adjusting mechanism in a conventional cutting plotter includes a cutter 8 for supporting a cutter blade 9 at its tip,
A holder 4 for supporting the cutter 8 and a carriage 1 for holding the holder 4 movably in the vertical direction are included. The holder 4 can move vertically along a guide 3 provided on the carriage 1. The holder 4 has an intermediate portion 4a, and the intermediate portion 4a is connected to the solenoid 6 via a cylinder 7. The upper part of the carriage 1 and the lower part of the holder 4 are connected by a spring 5, whereby the holder 4 is always urged upward.

When cutting a sheet-like material (not shown) using the cutter blade 9 of the cutting plotter, the solenoid 6 is energized, whereby the cylinder 7 is attracted and the cutter blade 9 is driven downward.

When the cutter pressure of the cutter 8 is adjusted using the conventional solenoid 6, the voltage applied to the solenoid 6 is adjusted, and the cutter pressure is adjusted by adjusting the force of the electromagnetic force.

The carriage 1 is driven by a driving device (not shown) in the vertical and horizontal directions of FIG. 4 with the cutter 8 held, whereby a sheet-shaped object can be cut at any position of the cutting plotter. ..

[0007]

Since the conventional cutter pressure adjusting device using a large solenoid capable of adjusting the cutter pressure is constructed as described above, the entire mechanism becomes large and complicated, and the device is expensive. There was a problem that became.

On the other hand, a cutter pressure adjusting mechanism having a simpler structure is shown in FIG. FIG. 5 is a schematic view of a main part in the vicinity of the cutter blade 9 of the cutting plotter shown in FIGS. 3 and 4, in which a solenoid (not shown) of the cutter pressure adjusting mechanism only moves the carriage main body 11 up and down. A small one is used. With reference to FIG. 5, the cutter pressure adjusting device having a simple structure includes a holder 14 for holding the cutter 8.
Are protrusions 12a and 12b provided on the carriage body 11.
It is possible to move up and down along the guide bar 15 between them. The guide rod 15 is provided with a spring 13 along the guide rod 15, which urges the holder 14 downward. As a result, the cutter 8 held by the holder 14 comes into contact with the sheet-like member with a predetermined pressure.

Since the conventional cutter pressure adjusting device having a simple structure is constructed as shown in FIG. 5, the structure is simple, but there is a problem that the cutter pressure is constant and the pressure cannot be adjusted. ..

The present invention has been made to solve the above problems, and an object thereof is to provide a cutting device having a cutter pressure adjusting device having a compact and simple structure.

[0011]

A cutting device according to the present invention includes a mounting means for mounting a sheet-shaped object, and a cutter provided to face the mounting means and for cutting the sheet-shaped object. And a cutter holding means for holding the cutter,
A spring urging means for urging the cutter holding means downward by a spring, and when the cutter is urged downward by the spring urging means, the cutter can be cut into a sheet-like member on the placing means. And adjusting means for adjusting the urging force of the spring urging means.

[0012]

The cutter comes into contact with the sheet-like member on the placing means through the cutter holding means, and the urging force of the spring urging means is adjusted by the adjusting means at this time.

[0013]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a diagram showing a main part of a cutting device according to the present invention, and corresponds to FIG. 5 described above.

With reference to FIG. 1, the periphery of the cutter of the cutting device according to the present invention is constructed as follows. A spring pressure adjuster 13 is provided on the protrusion 12a directly provided on the carriage body 11, and a spring 14 is provided on the spring pressure adjuster 13
And the holder 4 are provided along the guide bar 15.
A screw is provided between the protrusion 12a and the spring pressure adjuster 13, and the spring pressure adjuster 13 is movable in the vertical direction along the guide rod 15. Therefore, the spring pressure adjuster 13 should be rotated. The position can be moved up and down with respect to the protrusion 12a. As a result, the spring pressure adjuster 13 adjusts the downward pressing force of the spring 14. As a result, the cutter pressure of the cutter blade 9 on the sheet material 20 can be adjusted.

FIG. 2 is a diagram showing a second embodiment of the present invention. Referring to FIG. 2, in the second embodiment of the present invention, the spring 14 is provided along the guide rod 15 between the spring pressure adjusting bar 16 and the holder 4. Spring pressure adjustment bar 1
Reference numeral 6 is connected to the movable-side spring pressure adjuster 22, and the movable-side spring pressure adjuster 22 is provided with a ball 23 that is urged outward via a spring 24.

On the other hand, at a position facing the movable side spring pressure adjuster 22, there is provided a fixed side spring pressure adjuster 21 in which a plurality of recesses 25 are provided at intervals in the vertical direction. As the movable side spring pressure adjuster 22 moves in the vertical direction relative to the fixed side spring pressure adjuster 21, the vertical position of the spring pressure adjusting bar 16 changes. As a result, the biasing force of the spring 14 is changed, and the cutter pressure of the cutter blade 9 on the sheet material 20 can be adjusted.

Unlike FIG. 1, in FIG. 2, the biasing force of the spring 14 cannot be adjusted steplessly, but each recess 2
A desired cutter pressure can be obtained by appropriately selecting the position of 5.

[0018]

As described above, according to the present invention, the cutter of the cutting device is urged downward by the spring via the holder, and the urged cutter pressure is the spring using the screw structure or the latch structure. The cutter pressure is adjusted by changing the stroke of the cutter. As a result, it is possible to provide a cutting device having a compact and simple mechanism of the cutter pressure adjusting device.
