Description

[Detailed Description of the Invention] The present invention protects the surface of cut plates from stainless steel plates, aluminum plates, glass plates, etc., which may deteriorate quality due to surface flaws, during the packaging process of cut plates, etc. The present invention relates to a paper inserting device for inserting insert paper between cut plates for the purpose of the present invention.

Traditionally, insertion paper has been inserted by attaching a rolled paper to a steel strip and cutting the steel strip and the rolled paper at the same time with a cutting machine, or by attaching one end of the paper to the tip of a cut plate. There is a method of bending the roll paper, attaching it to the cutting board, and cutting the roll paper to match the length of the cutting board.

These methods are to apply static electricity to a steel strip or cut plate and attach the rolled paper to the steel strip, or to stick the tip of the rolled paper with the tip of the cut plate. In the former case, the rolled paper In order to cut the adhered steel strip, it is necessary to set a small clearance for the blade, and when removing the paper in the next process, if static electricity remains, it will be difficult to count the sheets, so static electricity must be removed.

In the latter case, as the cut plates are piled up, the folded part of the paper becomes thicker, causing folds or defects in the cut plate, and there is a risk of paper breakage due to the intermittent supply of roll paper. Therefore, various equipment is required to prevent paper from running out. Namely, it is a cutting plate centering device for perpendicularly abutting the tip of the cutting plate against the roll paper, and a device for creating a paper looper to prevent paper from breaking when the cutting plate hits the tip of the roll paper and pulls out the roll paper. It was a very large-scale device.

The inventors of the present invention have invented a simple paper loading device that does not require large-scale equipment as described above, and which presses rolled paper onto the top surface of a cutting board running on a belt conveyor or the like using a presser roller. The purpose of this paper is to cut the rolled paper to match the length of the cutting board.

Hereinafter, the present invention will be explained in detail with reference to embodiments shown in FIGS. 1 to 3.

First, 1 is a roll paper, and a support shaft 20, a clutch 18, and a brake 19 are installed on the central extension shaft of the roll paper 1.

Furthermore, the rubber roller arm 21 is equipped with a rubber roller 15 and a motor 17 that can be switched between high and low speeds.
6, and a cylinder 16 for pressing a rubber roller 15 against the o-roll paper 1 is provided, and a sprocket 27 of this chain 26 has a built-in one-way latch.

A roll paper feeding device 24 made up of these components is provided. Rotary cutter 1 between guide plates 3 and 4
4, and the arm 22 is further provided with a paper pressing device 25 comprising a presser roller 7 to which a cylinder 8 is attached.

Next, a belt conveyor is passed around pulley 10.
and a detector above it, for example, a phototube 12, 6 for detecting a cut plate.
A paper detection phototube 13 is provided.

In addition, 2 is a paper unwound from a roll paper, 11 is a cutting board, and 5
is a guide roller.

Describing the operation of the paper loading device 23 configured as described above, the roll paper 1 attached to the support shaft 20 is rotated by the rubber roller 15 and sent out at a low speed in the direction of arrow A.

When the leading edge of the rolled paper 1 reaches the soil surface of the belt conveyor and is fed further, the leading edge of the rolled paper 1 reaches the lower part of the presser roller 7 as shown in FIG. reach

Then, the phototube 13 installed at the bottom detects its tip, and the rotation of the motor 17 is stopped by the detection signal.
The feeding of the paper 2 is stopped. In such a state, when the phototube 6 detects the tip of the cutting plate 11 that is being intermittently conveyed in the direction of the arrow on the belt conveyor 9,
First, the motor 17 is started at high speed by the detection signal, and the rubber roller 15 rotates the roll paper 1, and the leading edge of the paper 2 is
The liquid flows out from the lower part of the presser roller 7 toward the mouth. Furthermore, paper 2
The outflow speed of the cut plate 11 is set lower than the conveyance speed of the cut plate 11. On the other hand, when the phototube 6 detects the tip of the cutting plate 11, the presser roller 7 is activated by a timer that is set in advance for a predetermined time depending on the distance between the phototube 6 and the presser roller 7 and the conveyance speed of the belt conveyor 9. It operates in the direction of arrow C to press the paper 2 against the cutting plate 11 together with the leading edge of the paper 2 and the cutting plate 11 .

Incidentally, when the presser roller 7 completes its movement in the direction of the arrow, the motor 17 stops.

On the other hand, since a one-way clutch is built into the sprocket 27 of the chain 26, when the paper 2 is pressed against the cutting plate 11 by the presser roller 7, the roll paper 1 is moved by the conveying force of the cutting plate 11 due to the pressure contact force. It is then pulled and unwound by the tension.

Next, the belt conveyor speed and rotary cutter 14
When the phototube 12, which is set in advance at a predetermined position according to the installation position of the paper, detects the rear end of the cutting plate 11, the rotary cutter 14 operates in the two directions of the arrows in response to this detection signal, and cuts the paper. Cut 2. With this rotary cutlet 14,
The paper 2 cut into a predetermined length is pressed onto the cutting plate by a presser roller 7 up to its rear end. In this way, the cutting board 11
Stack paper 2 on top and finish the paper insertion work.

On the other hand, the start signal of the rotary cutter 14 causes the rotary cutter 1 to
3 are connected, and the rotation of the roll paper 1 is stopped by the brake 19.

When the rotation of the roll paper 1 stops, the tarlage 18 is turned off, and then the motor 17 is started, and the roll paper 1 is sent out at a low speed, and the state shown in FIG. 1B is waited for the arrival of the next cut plate.
The rotation of the motor 17 (the circumferential speed of the rubber roller 15, that is, the feeding speed of the roll paper 1) can be switched between high and low speeds, and the rotation satisfies the following formula. ≧1>2 However, V: Cutting plate feeding speed V: Roll paper high speed feeding speed V2: Roll paper low speed feeding speed In other words, when the presser roller 7 presses the tip of the cutting plate 11,
A sudden tensile force is applied to the paper, which may cause it to break.

To prevent this, it is desirable to bring V1 closer to V. As described above, the present invention does not require a paper looper and is provided with a motor and a rubber roller for unwinding the roll paper, which prevents paper breakage at the start of unwinding and enables highly accurate paper insertion. , moreover, the device is simple;
This is a device with very excellent functionality and low equipment cost.
