Description

[Detailed Description of the Invention] The present invention automatically performs plate making and printing just by inserting a manuscript.
This relates to a fully automatic plate making/printing machine that performs printing, and is particularly characterized by its plate ejection mechanism.

Conventionally, with printing machines that wrap stencil paper around a printing cylinder and perform high-rise printing, once printing is completed, workers have to manually peel off the used stencil paper from the printing cylinder and dispose of it, which is very time consuming. It's a hassle,
In addition, the printing ink has the disadvantage that it adheres to hands and clothes and stains 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.

FIG. 1 is an overall configuration diagram showing one embodiment of the present invention. 1 is a plate feeding mechanism that transports a roll of base paper and cuts it into a predetermined length; 2 is a plate feeding mechanism that presses the original and base paper with a predetermined pressure; A plate-making mechanism that performs heat-sensitive flash plate making using a flash discharge tube; 3 a plate feeding mechanism that attaches the stencil paper that has been made and cut to a predetermined length to a printing cylinder; and 4 that performs mimeograph printing using stencil paper fed to the printing cylinder. 5 is a printing mechanism that removes used base paper from the printing cylinder after printing and processes it; 6 is a paper feed mechanism that supplies printing paper to the printing mechanism 4 during printing; 7 is a paper discharge mechanism that discharges the printed paper. It is a mechanism.

Further, 8 is a document insertion table, 9 is a document, 10 is a rolled base paper, 11 is a document discharge table, 12 is a paper feed table, 13
is printing paper, 14 is a paper output table, 15 is printed paper, 16 is a base paper cutter, 17 is printing ink, 1
8 is a paper feed cassette, and 19 is a printing cylinder.

FIG. 2 shows the structure of the plate discharge mechanism 5 in FIG.
2 is a plate removal claw, 23 and 24 are a pair of upper and lower plate removal rollers,
25 is a plate feeding guide, 26 is a fixed arm fixed to the main body, 27 and 28 are compression arms, 29 is a compression plate, 30 is a compression lever, 31 is a compression disc, and 32 is a plate discharge case having a handle 33.

In the above configuration, when the original 9 is inserted from the original insertion table 8 and the power is turned on, the plate feeding mechanism 1 is activated.
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 polymer of the original 9 and the rolled base paper 10 with a predetermined pressure and makes a heat-sensitive flash plate using an electronic flash discharge tube. While the plate is being made, the plate is sent to the plate feeding mechanism 3 by the plate feeding mechanism 1. The rolled base paper 10 is
After the document 9 passes through the base paper cutter 16, it is cut into a predetermined length by the base paper cutter 16. on the other hand,
Original 9 and rolled base paper 1 sent to plate feeding mechanism 3
The 0 polymer is 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 tray 12 is transferred to the paper feed mechanism 6.
The printed paper 1 is sent to the printing mechanism 4 by
5 is delivered to the paper ejection table 14 by the paper ejection mechanism 7. This is how a fully automatic plate making/printing machine operates. When printing is finished, the rolled base paper 10 is peeled off from the printing cylinder 19 by the plate discharge mechanism 5 and processed.

The master ejecting mechanism 5 will be explained in detail based on FIG. 2. When the printing process is completed and a signal to start plate discharge is received, the plate removal claw 22 is set from the position A to the position B. When the printing cylinder 19 starts rotating in the direction of the arrow in this state, the leading end of the discharged master paper 21 that is in close contact with the screen 20 is peeled off from the screen 20 by the master removal claw 22 and sent to the master removal roller 23 .
When the plate removal rollers 23 and 24 are rotated in synchronization with the rotation of the printing cylinder 19, the plate discharge base paper 21 is moved to the plate feeding guide 2.
5. The plate discharge case 3 passes through the plate removal rollers 23 and 24.
Sent into 2. At this time, the compression plate 29 is in position C, but the compression disk 31 is moved by a motor (not shown), etc.
When rotated half a turn by
As shown in FIG. 2, the compression plate 29 moves to the second position with the fixed arm 26 as a fulcrum by the action of the compression lever 30, which is connected to the compression arm 27 and the other end to the joint of the compression arms 27 and 28, as shown in FIG. When the compression disk 31 is continuously rotated, the compression plate 29 is reciprocated between C and D.

Therefore, the plate discharge base paper 21 is transferred to the plate removal rollers 23 and 24.
By the action of the compression plate 29, the sheet is compressed and sent to the back of the discharge case 32. Discharge case 32
When the inside is filled with the discharge master paper 21, the master discharge case 3
The plate discharge case 32 can be taken out by holding the handle 33 of No. 2, and the plate discharge base paper can be discarded, so that the plate discharge process can be easily carried out without staining hands or clothes. When the plate discharge process is completed, the plate removal claw 22 is returned to the position A so as not to interfere with the rotation of the printing cylinder, and the compression plate 29 is also returned to the position C, so that the plate discharge case 32 of the discharged master paper 21 at the time of the start of plate discharge is Needless to say, it is preferable to design the plate discharge case 32 in such a way that it does not obstruct entry into the plate, and also does not obstruct attachment and detachment of the plate discharge case 32 when discarding the plate discharge base paper 21.

As described above, according to the present invention, plate making and printing can be performed automatically just by inserting a manuscript, and furthermore, the plate discharge mechanism is configured to compress the used base paper with a compression plate and store it in the plate discharge case. Not only does the storage space for the waste plate paper become smaller and more compact, but the paper waste case can also be held when disposing of the waste plate paper, making it easy to dispose of the plate waste without getting your hands or clothes dirty with printing ink. Its industrial value is great.
