Printing block discharge device of stencil printing device and stencil printing device

Abstract

The invention provides a discharge forme device of a permeographic printing device and the permeographic printing device, which can prevent falling of an original edition after use when the original edition separates from an accepting part and prevent defacing within the device body even in a state that a great amount of used original editions are received within a discharge forme container. The discharge forme device comprises: a discharge forme container, capable of freely assembling and disassembling the accepting part relatively to the device body, for receiving the used original edition erosived from a plate cylinder via an opening disposed on an upper section thereof; and an original edition pressing part supported over the opening during freely rotating. The original edition pressing part occupies a retreat position non-interfering with a discharge forme path when the discharge forme container is arranged within the device body; or occupies a pressing position for pressing the used original editions received in the discharge forme container over the opening when the discharge forme container separates from the device body. A protruding part for hooking the used original editions is provided on the original edition pressing part while in a pressing position.

Description

technical field [0001] The present invention relates to a stencil printing device, and more specifically, to a printing plate discharge device that peels a used original plate from a printing plate cylinder and stores it therein. Background technique [0002] The known digital heat-sensitive stencil printing is printed by using a freely rotatable printing plate cylinder formed by wrapping a resin or metal mesh screen in multiple layers on a porous support cylinder, and A porous support made of Japanese paper fibers or synthetic fibers or a mixture of Japanese paper fibers and synthetic fibers is bonded to a thermoplastic resin film (generally about 1 to 3 μm in thickness) to form an original plate with a laminated structure. After the thermal head is heated and perforated for plate making, the thermoplastic resin film surface of the original plate is wound on the printing plate cylinder, and the ink is supplied to the inner peripheral surface of the printing plate cylinder b...

Problems solved by technology

[0013] However, according to the experimental results of the present inventors, when the used original plate 94 is stored and loaded in a large amount in the container main body 92b, as shown in FIG. 20, the height of the used original plate 94 becomes very high. After use, the original plate 94 is pressed, and when it is released from the storage portion 91 to the discharge printing plate container 92, the used original plate 94 also slips from the gap between the pressing member 99 and the container main body 92b, so there is a possibility that the main body of the device will be damaged. The problem of internal pollution

[0014] Moreover, in the above-mentioned discharge printing plate device 90, in order to prevent the original plate 94 from sticking to the discharge printing plate receiving member 96 after use, the rib 98 is formed in an arc shape, but when the discharge printing plate container 92 is detached from the device main body Sometimes, the original plate 94 will be hooked to the arc-shaped part of the rib 98 after use, and the original plate 94 will fall after the use of the hook, and the inside of the main body of the device will be polluted.
