Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an auxiliary clamper device in a cutting machine.

<Problems to be solved by this invention> When cutting stacked sheets with a vertically moving blade on the table of a cutting machine, there is a problem that the cutting paper in front of the blade is scattered by the cutting pressure. . The present invention is intended to solve such a problem.

<Construction of the Invention> The present invention is provided with a cutting blade 2 on a cutting machine table 1 and an intermediate plate 3 which is in contact with the upper end portion of the blade 2 and the upper half of the front surface and moves up and down together with the blade 2. An inclined surface 3a that lowers the blade 2 side is provided in the lower portion of the middle plate 3, the lower end of the inclined surface 3a is below the blade 2, the upper end is above the middle of the inclined surface 3a, and the inclined surface 3a.
The auxiliary clamper device in a cutting machine is characterized in that an auxiliary clamper 4 having a polygonal thick body made of an elastic material such as a sponge having a sloped surface is attached so as to be vertically movable.

<Operation> When the stacking paper a to be cut is placed on the cutting machine table 1 and the blade 2 is moved downward, the auxiliary clamper 4 first comes into contact with the upper surface of the stacking paper a, and then the rear clamper. After the paper is pressed down at 10, the auxiliary clamper 4 buffers the stacked paper a while self-compressing by the downward movement and cuts by the downward movement of the blade 2.

Since the cushioning press of the cutting paper by the auxiliary clamper 4 is literally flexible, as shown in FIG. 2, the cutting paper a in front of the blade 2 sequentially moves forward in the descending approach of the blade 2 and the inclined surface 3a of the middle platen 3. Will be cut smoothly. The auxiliary clamper 4 adjusts the mounting position upwards as shown in FIG. 4 when the stacking of the cut paper is increased, especially when the blade width is narrowed by re-polishing and exchanging the blade 2, and the blade is continuously smoothed. To hold the cushion in place. The auxiliary clamper 4, which is compressed by cutting, returns to its original shape by the upward movement of the intermediate plate 3 together with the blade body 2 and is prepared for the next presser foot.

<Example> An example will be described below with reference to the drawings.

A cutting blade 2 is provided on a cutting machine table 1 so as to move up and down, and an intermediate plate 3 that comes in contact with the upper end surface of the blade 2 and an upper half of the front surface and moves up and down together with the blade 2 is provided. An auxiliary clamper 4 having a thick polygonal part made of a sponge having an inclined surface along the inclined surface 3a is provided on the inclined surface 3a provided on the lower portion of the intermediate plate 3 and having the blade 2 side lowered. Install. The lower end of the auxiliary clamper 4 forms a flat surface and is normally positioned lower than the cutting edge of the blade 2.

When mounting the auxiliary clamper 4, as shown in FIG. 1, a support plate 5 is attached to the upper surface of the auxiliary clamper 4.
A mounting plate portion 6 that bends more along the inclined surface 3a is provided, and a bolt 7 is inserted from the inside of the mounting plate portion 6 toward the inclined surface 3a and stopped, or the inverted plate V is inverted as shown in FIG. The mounting member 8 having a shape is sandwiched and bolted to be mounted. In FIG. 1, reference numeral 9 is a cutting line that divides the auxiliary clamper 4 into upper and lower parts. The upper half portion 4a on the cutting line is temporarily expanded based on the adhesive portion under the support plate 5 and the bolt 7 is put in and taken out. I decided to do it. Further, the stop hole 6a of the mounting plate portion 6 is elongated in the vertical direction so that the auxiliary clamper 4 can be vertically moved and adjusted. The mounting member 8 of FIG. 5 is provided with elongated holes 8a and 8b for fixing the bolts 7 so that the auxiliary clamper 4 can be moved and adjusted in the vertical and front-back directions.
In the figure, 10 is a rear clamper of the blade 2.

The stacking paper a that is placed on the cutting machine table 1 in alignment is
The auxiliary clamper 4 in front of the blade 2 descending together with the blade 2 is buffer-pressed by the contact with the auxiliary clamper 4, and subsequently the clamper 10 behind the blade 2 is lowered to press the rear part of the stacking paper a and then the middle plate. By the descent of 3, the blade body 2 moving downward cuts.

Although the auxiliary clamper 4 descends together with the blade body 2, the auxiliary clamper 4 expands and compresses in the forward direction of the inclined surface 3a by the pressure contacting the stacking paper a, and the stacking paper a continues to be compressed even if the cut portion moves forward. The cushioning is continued to prevent the stacking paper a in front of the blade 2 from scattering. When the cutting operation is completed and the blade 2 is pulled up, the auxiliary clamper 4 elastically expands to the original shape and waits for the next cutting operation.

<Effect of the Invention> As described above, the present invention attaches an auxiliary clamper in the form of a polygonal thick body made of a sponge that elastically expands and contracts to the lower part of the middle plate that moves up and down together with the blade body so that the vertical movement can be adjusted. At the time of cutting, the cutting paper in front of the blade is buffered by the auxiliary clamper, so that the cutting paper scatters or becomes dirty due to the cutting pressure, and the effect of eliminating the trouble of realigning the stacks is eliminated. Occurs.

Further, the auxiliary clamper has an effect that it can be easily formed and replaced by the polygonal thick body shape made of an elastic body such as sponge.
