Abstract

PURPOSE:To automatically perform plate making and printing operations by combining a plate feeding mechanism, a plate making mechanism, a plate supply mechanism, a plate discharge mechanism utilizing used paper rolls for winding used papers, a paper supply mechanism, and a paper discharge mechanism in such a way as to enable them to perform their specific actions. CONSTITUTION:A rolled manuscript paper 10 is cut into a given length by a cutter 16 after a manuscript 9 passed through the inside of the cutter 16. Of a combination of the manuscript 9 sent to the plate supply mechanism 3 and the rolled manuscript paper 10, the separated manuscript 9 is sent out to a manuscript discharge base 11, and the rolled paper 10 is supplied to a printing cylinder 19. After the supply of plate is ended, the printing mechanism 4 begins to operate in response to a printing start signal. A printing paper 13 set on the paper supply base 12 is sent out to the printing mechanism 4 by the paper supply mechanism 6. After the ending of printing, the rolled paper 10 is separated from the printing cylinder 19 by the plate discharge mechanism 5. The supply of rolled paper tube 27 to the plate discharge mechanism 5 is made by using the used vacant paper tube for the rolled paper 10.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a plate-making/printing machine that automatically performs plate-making and printing simply by inserting a manuscript, and is particularly characterized by a plate-discharging mechanism.

Conventionally, with printing machines that perform mimeograph printing by wrapping stencil paper around a printing cylinder, once printing is completed, the operator has to manually peel off the used stencil paper from the printing cylinder and dispose of it, which is very troublesome. In addition, the printing ink has the disadvantage that it adheres to hands and clothes, staining them.

The present invention solves the above-mentioned drawbacks, and one embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

The paper tube holder A133 is a paper tube holter B that is rotatably held by the tension knob 34 and holds the rolled paper tube 27 together with the paper tube holder A.

FIG. 7 is an enlarged view of the rolled base paper 10 in FIG. The stencil printing base paper 37 is wound into a roll.

FIG. 8 is a diagram showing how the first sheet of base paper 21 is wound onto the roll paper tube 27, and the adhesive 35 such as double-sided tape provided at multiple locations on the surface of the roll paper tube 27 has the release paper 36 peeled off. in a state.

In the above configuration, the original 9 is inserted from the original insertion table 8,
When the power is turned on, the plate feeding mechanism 1 is activated, and the original 9 and the rolled base paper 10 are superimposed and sent to the plate making mechanism 2. The plate-making mechanism 2 is a mechanism that presses the original 9 and the rolled base paper 100 polymer at a predetermined pressure, heat-sensitive flutters and plate-making using an electronic flash discharge tube, and processes the original 9 and the rolled base paper 10 polymer in several steps. While the plate is being made, the plate is sent to the plate feeding mechanism 3 by the plate feeding mechanism 1. Rolled base paper 1o or manuscript 9
After passing through the base paper cutter 16, the base paper cutter 16 cuts the paper into a predetermined length. On the other hand, the original 9 fed to the plate feeding mechanism 3 and the rolled base paper 100 polymer are separated, the original 9 is sent to the original discharge table 11, and the rolled base paper 10 is fed to the printing cylinder 19. When plate feeding is completed, the printing mechanism 4 starts operating upon receiving a signal to start printing. At this time, the printing paper 13 set on the paper feed table 12 is sent to the printing mechanism 4 by the paper feed mechanism 6, and the printed paper 15 is sent to the paper delivery table 14 by the paper discharge mechanism 7.

This is how a fully automatic plate making/printing machine operates. When printing is finished, the rolled base paper 1o is peeled off from the printing cylinder 19 by the plate discharge mechanism 5 and processed.

Here, the master discharge mechanism 5 will be explained in more detail with reference to FIGS. 2 to 8. FIG. 2 is a diagram after printing is completed and before the plate discharge mechanism 5 starts operating. A base paper 21 is fed onto a screen 20 stretched over a printing word 19, and one end of the base paper 21 is held by a base paper feed clamp 22. FIG. 3 shows the plate discharge mechanism 5 in operation, and shows the printing lI1. ,119
rotates by a predetermined angle, and the base paper feed clamp 22 releases the base paper 21.
When the suction airflow conduit 23 is rotated by the conduit drive motor 3o, the suction cup 24 stops at a position facing the base paper 21. Then, a suction fan (not shown) is powered on, negative pressure is generated within the suction cup 24, and one end of the base paper 21 is suctioned by the suction cup 24. FIG. 4 is a diagram before the plate ejecting mechanism 5 finishes operating, and the suction cup 24 is attached to the base paper 2.
The suction air flow conduit 23 rotates in the opposite direction while adsorbing one end of the paper roll 1, and stops at a position above the paper roll tube 27. Then, the power to the suction fan is turned off, and the base paper 21 separates from the suction cup 24 and falls onto the discharged master paper 28. When the rolled paper tube 27 begins to rotate by the paper tube drive motor 31, the screen 2 of the base paper 21
Since ink is attached to the side facing o, the base paper 21 is adhered to the discharge base paper 28 due to its viscosity and is wound up. When the winding of the base paper 21 onto the roll paper tube 27 is completed, the paper tube drive motor 31 is stopped, and the operation of the plate discharge mechanism 6 is completed. When the discharged master paper 28 reaches a predetermined number or more, pull the knob 34 of the paper tube holder B33 and remove the rolled paper tube 27.
Dispose of the product while it is still wrapped in it. Further, the paper roll tube 27 can be replenished into the plate discharge mechanism 6 by using a used empty paper tube for the rolled base paper 10. In the plate discharge mechanism 5, the role of the pressure roller 25 is to apply a certain amount of tension to the base paper 21 when the base paper 21 is wound onto the paper roll tube 27, and to apply sufficient pressure to prevent the base paper from becoming thick.

FIG. 8 is a diagram showing how the first sheet of base paper 21 is wound onto a roll paper tube 27. Generally, the surface of the roll paper tube 27 is smooth, and although printing ink is attached to the surface of the base paper 21 facing the screen 2o, when the first sheet of base paper 21 is wound onto the roll paper tube 27, the surface of the base paper 21 However, it is difficult to roll the paper by sliding on the surface of the roll paper tube 27. However, as in the actual gun example, by providing an adhesive 36 such as double-sided tape at multiple locations on the surface of the rolled paper tube 27, the rolled paper tube 27
It is clear from FIG. 8 that it is easy to start winding the base paper 210. Further, this rolled paper tube 27 may be supplied to the user in a state as shown in FIG. 7 as a paper tube for the rolled base paper 10. At this time, the roll paper tube 2 of the stencil printing base paper 37
7 A release paper 36 is placed on the adhesive 35 such as double-sided tape to prevent the part that comes into contact with the surface (the beginning of winding in the manufacturing process of the rolled base paper 10) from adhering to the roll paper tube 27.
It is desirable to have a

As described above, according to the present invention, plate making and printing can be performed automatically just by inserting the original, and furthermore, the plate ejecting mechanism uses the paper tube of the rolled base paper for winding up the used base paper. It takes advantage of the advantages of a fully automatic plate making and printing machine that uses paper base paper, and when disposing of used base paper, the entire roll paper tube can be disposed of, so post-processing can be done without staining hands or clothes. Value is great.
