Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a cutter blade for a cutting plotter.

(Prior Art) Conventionally, cutter blades have been used for cutting pattern materials, especially paper patterns.

Since the paper receiver cut by the drive source moves up and down directly on the surface, the driving force is directly transmitted to the surface of the paper receiver. Also, the cutter blade used for cutting only has one side.

(Problem to be solved by the invention) Therefore, since the cutter blade is forced to descend during cutting, the pressing force becomes excessive, which causes rapid wear of the cutter blade and causes the cutter blade to get tangled with the paper and cause wrinkles. Cheap.

In addition, the cutter blade receiver is easily scratched on the contact surface of the cutter, and the height adjustment of the cutter blade relative to the paper is delicate and difficult to adjust.

On the other hand, since the cutter blade is a single-sided blade, when changing the cutting path by the cutter blade, there is a drawback that the rotation angle β of the cutter blade increases due to the changed path of the cutter blade, as shown in FIG.

In view of this, in the first invention, the pressure applied to the cutter blade is moderated to prevent blade wear, and in the second invention, the rotation angle of the cutter is reduced to improve work efficiency. The purpose of this invention is to provide a cutter blade for a cutting plotter.

(Means for solving problems) In order to achieve the above object, the first invention of the present application is as follows.

The cutter blade receiver provided on one outer surface of the housing-shaped main body frame has a first unit movable in the longitudinal direction along the surface, and a head provided on the first unit for attaching the cutter blade, A second unit movable in a direction perpendicular to the moving direction of the first unit, and a roll material installed in the main body frame, and the cutter blade holder pulls out the shape material from the roll material along the surface of the main body frame. A cutting plotter that performs cutting by movement of the first and second units, characterized in that the head is provided with means for raising and lowering the cutter blade and a buffer means independent of this, so that the pressing force of the cutter blade can be adjusted. A second aspect of the present invention is the above-mentioned cutting plotter, characterized in that the blade surface of the cutter attached to the head is provided on both sides, and the angle of the blade during cutting can be changed by a rotation motor provided on the head. shall be.

(Function) With the above configuration, in the first invention, the force that presses the cutter blade against the surface of the cutter blade receiver is adjusted by the buffer means, and in the second invention, the blade surface of the cutter is provided on both sides. It is possible to shorten the time needed to change the angle of the blade during cutting.

(Embodiments) The present invention will be described below with reference to embodiments shown in FIGS. 1 to 4.

As shown in FIG. 1, the cutter blade of the cutting plotter according to the present invention has a cutter blade holder provided on one outer surface 3 of a housing-shaped main body frame 2, and a first unit 5 that is movable in the longitudinal direction along a surface 4. and.

A second unit 6 is provided in the first unit 5, has a head 7 for attaching a cutter blade, and is movable in a direction perpendicular to the moving direction of the first unit 5; a shape material 9 drawn out from the roll material 8 along one outer surface 3 of the main body frame 2;
In the cutting plotter 1 which cuts by the movement of the first and second units 5.6, the first invention is characterized in that the head 7 is provided with a lifting means 18 for the cutter blade 10 and a buffering means 19 independent of the lifting means 18. In the second invention, the blade surface lOa of the cutter blade lO attached to the spatula 7 is provided on both sides, and the angle of the blade 10 during cutting is controlled by a rotation motor 20 provided on the head 7. It consists of a configuration that allows changes to be made.

More specifically, the main body frame 2 has a vertical box-like shape, has an outer surface 3 that is inclined so that the upper part is thinner and the lower part is thicker, and has a base 1 of a constant height that extends horizontally from the base line 11 of the inclination.
2 is provided.

A roll material 8 is placed inside the base 12, and the shape material 9 of the roll material 8 is inserted into the outer surface 3 from the gap between the base 12 and the outer surface 3.
It is adapted to be pulled out along the guide roller 13.

Paper pressers 14 are provided at the upper end and left and right ends of the outer surface 3 to hold the drawn-out shape material 9, respectively.

The first unit 5 is attached to both sides of the outer surface 3 so as to be vertically movable so as to cross the outer surface 3.

The vertical movement of the first unit 5 is performed by converting the rotation of a motor (not shown) into a known reciprocating movement.

Further, the left and right movement of the second unit 6 is also carried out by changing the rotation of a left and right movement motor 15 provided on one side of the first unit 5 to a known reciprocating motion. This is an unrelated pen head.

In FIG. 2, the second unit 6 includes a cutter blade lifting motor 21 and a head 7 that is lifted and lowered by this motor 21.
The head 7 is provided with an encoder 22 . Coupling 23. Cutter rotation motor 20. Slider 24. and a cutter blade unit 25.

The cutter blade lifting motor 21 is provided with a pinion 27 directly connected to its rotating shaft 26, and this pinion 27 moves a rack 28 provided on the slider 24, so that the head 7 itself moves up and down. .

On the shaft 29 of the rotation motor 20.

A cutter blade unit 25 is rotatably connected to the slider 24 via bearings 30 and 30 installed therein.

The cutter blade unit 25 consists of a unit main body 31° and a shaft holder 32. Spline shaft 33° holder support 3
4, etc., and the unit body 31 has a shaft holder 32. The spline shaft 33 is installed inside in this order, and the spline shaft 33 is connected at the lower part to a cutter holder 35 to which the cutter blade 10 is connected by a pin 36 or the like.
The cutter blade 10 is attached to the cutter holder 3'5 by positioning.

Further, a seat 37 for a buffer means 19 such as a spring is provided on the upper part of the spline shaft 33, and the buffer means 19 is provided in a space 38 between the spline shaft 33 and the unit body 31.

The buffer means 19 allows the cutter blade 10 to move up and down within the range of deflection. At this time, the shaft holder 32 guides the spline shaft 33 when it goes up and down.

Note that the holder support 34 transmits the rotation of the unit body 31 to the shaft holder 32.

According to the first invention of the present application, when the lifting motor 21 rotates, the cutter blade unit 25 is moved up and down via the slider 24 due to the engagement of the pinion 27° rack 28, but the cutter blade 10 does not cut. When cutting the shaped material 9 to be cut, the cutter blade unit 25 is lowered, and the cutter blade lO is pressed against the surface 4 of the shaped material 9 to be cut and the cutter blade holder.

However, since the pressing force of the cutter blade 10 can be adjusted using a buffer means 19 such as a spring, it is possible to prevent excessive force from being applied to the cutter blade 10.

The second invention of the present application also has a canter blade 10 with blade surfaces 10a on both sides, as shown in FIG.

This allows the angle of the cutting edge to be adjusted to 30' to 15° as shown in Figure 3.
It is said that

To change the blade angle of the cutter blade lO during cutting, rotation is transmitted to the holder support 34 by rotating the rotation motor 20, and the rotation is transmitted to the shaft holder 32.
Since the spline shaft 33 rotates through the cutter holder 35, the cutting edge of the cutter blade 10 can be rotated via the cutter holder 35.

FIG. 4 shows the turning angle α when blade surfaces are used on both sides.Compared to the single side shown in FIG. 5, the turning angle can be 90° or less in the case of both sides.

(Effects of the Invention) Since the present invention is configured as described above, in the first invention, the pressing force of the cutter blade can be adjusted by the buffer means of only the cutter blade, and the motor for vertical movement of the cutter blade can be adjusted as in the conventional case. There is no need to fine-tune the stop position of the product, which reduces the time required for assembly and test runs.Furthermore, since it is pressed by a spring, the constant pressure setting range is wide and it can follow changes in the thickness of the mold material.

Furthermore, since the wear of the cutter blade is reduced, a stable cutting time can be maintained, and the contact surface of the cutter blade is also free from scratches, which eliminates problems such as running along the scratches.

For the second invention, when cutting into an arbitrary shape of the material, if you use one double-edged blade, you can use the different blade surfaces to change the direction by rotating the cutting edge up to 90" (rotation range 90°) when changing the course. Moreover, since the rotation angle is small, the time for changing the direction can be shortened, and the contact resistance with the paper during one rotation can be reduced.
