Description

[Detailed Description of the Invention] The present invention relates to an improvement of a paper holding device in a cutting machine.

Normally, a cutting machine has a paper holding member called a fit to set the cutting size by aligning the trailing edge of the paper to be cut, and a feeding device to move this member back and forth on a receiving plate. is provided.

Conventionally, this paper presser uses a scale to measure the position corresponding to the paper cutting size, and then moves the paper presser member to that position, but the position of the paper presser member is scaled every time the paper cut size changes. You have to measure and change accordingly.

This method has the disadvantage that positioning work is time-consuming.

The present invention was completed with the aim of solving the above-mentioned drawbacks and providing a paper holding device for a cutting machine that can feed the paper feeding member quickly and accurately.
The present invention will be described in detail with reference to the illustrated embodiments.

In the figure, reference numeral 1 denotes a paper presser member commonly known as a "fitsun". and set the size of the paper pieces to be cut by the cutter 3.

A bracket 4 is fixed to the rear surface of the paper presser member 1 with bolts, and the bracket 4 has its legs 6 projecting downward through the slit 5 formed in the receiving plate 2. A guide rail 7 parallel to the slit 5 passes through a guide tube 6' provided at the lower end of the leg 6.

On the other hand, below the receiving plate 2, front and rear pulleys 8 and 9 are provided at a required interval with their rotational axes oriented perpendicular to the slit 5 so that they are on a line parallel to the slit 5 and the guide rail 7. There is a wire 1 between both pulleys 8 and 9.
0 is suspended.

In the illustrated embodiment, the front pulley 8 is a wire drum type drive wheel, while the rear pulley 9 is a driven wheel, but the present invention is not limited to this.

The rotation shaft 8' of this front pulley 8 is connected to the spur gear 12.
This spur gear 12 meshes with a spur gear 25 attached to a rotating shaft 14 of a rotating handle 13 provided on the side surface of the cutting machine to constitute a gear mechanism.

Further, since the wire 10 described above is fixed to the leg part 6 of the bracket 4 by a fixture 16, the rotary nozzle 13 connects the front pulley 8 from the outside via a gear mechanism.
When the wire 10 is rotated, the wire 10 moves, and at the same time, the bracket 4 and the paper presser member 1 connected to the upper end thereof are fed along the guide rail 7.

Also, bevel gears 17 and 19 are attached to the rotation shafts 8' of the pulleys 8 and 9.
A digital counter 18 that displays the amount of movement of the paper presser member 1 is connected via the digital counter 18.
The display is set to correspond to the distance between the paper presser member 1 and the cutter 3, so that the amount of movement of the paper presser member 1 is displayed in millimeters.

With this structure, when a piece of paper is placed on the upper surface of the receiving plate 2 and the rotating handle 13 is rotated from the outside, the front pulley 8 is rotated via the rotating shaft 14 and spur gears 15 and 12. The wire 1 is suspended between the pulley 9 and the rear pulley 9.
Since the wire 10 also rotates, the leg part 6 of the bracket 4 is projected downward through the slit 5 of the receiving plate 2.
The paper holding member 1, which is attached to the leg 6 in the middle of the paper, moves without rattling and pushes the rear end of the paper to a predetermined position according to the cutting size, and at the same time is connected to the rotating shaft 8' of the pulley 8. The paper holding member 1 is suspended by the digital counter 18.
As the amount of movement is displayed, digital counter 1
The feeding position of the paper presser member 1 can be determined accurately while looking at the display 8, and since the paper presser member 1 is moved by the means described above, it is faster than a screw type feeding device. You will be able to move around.

In this embodiment, since the digital counter 18 is linked to the rotating shaft 8' of the front drive-side pulley 8, the digital counter 18 is connected to the rotating shaft 9' of the driven-side pulley 9. Display errors can be reduced.

As is clear from the description of the above embodiments, the present invention uses a set of wires for feeding the paper presser member, and a digital counter that displays the amount of movement of the paper presser member is linked to the rotation shaft of the drive-side pulley. The position of the presser member can be accurately moved and set without using a scale, and the paper presser can be fed extremely quickly and easily, making it practical as it eliminates the drawbacks of the paper presser device of conventional cutting machines. The value is extremely great.

Claims (1)

[Scope of utility model registration request] The bracket 4 of the paper pressing member 1 is made to protrude downward from the receiving plate 2 through the slit 5 formed in the receiving plate 2, and is guided by a guide rail 7 parallel to the slit 5 provided on the lower surface of the receiving plate 2. Below the receiving plate 2, front and rear pulleys 8, 9 with rotating shafts 8', 9' located in a direction perpendicular to the slit 5 are provided at a required interval, and a wire 10 is suspended between the pulleys 8, 9. At the same time, the bracket 4 is attached to the middle of the wire 10, and a paper presser is attached to the rotating shaft 8' of the drive-side pulley, which is rotated by the rotating bundle 13 through a gear mechanism among the pulleys 8.9. A paper holding device for a cutting machine, characterized in that a digital counter 18 for displaying the amount of movement of a member 1 is connected.
