A printing machine in which substantial automation of the replacement procedure is achieved, and thus significant simplification of replacement procedure, and reduction of time required for the procedure are achieved is provided. The printing machine comprises an ink fountain member 2, an ink fountain roller 3, a strip of sheet 39 of which middle part is placed over the ink fountain member 2, a sheet moving device 40, a pair of barrier plates 53 attracted to the ink fountain member 2 under the sheet 39 and attracted to the outer peripheral surface of the ink fountain roller 3 by a permanent magnet, a cleaning tank 56, a cleaning blade 57, a reciprocating device 58, a barrier plate replacing device 85, a plurality of ink containers 65 accommodating different types of ink and being stored in a container storage unit 66, and an ink supply device 86 for holding the desired ink container 65 and supplying the ink therein to the ink fountain 1.
A printing machine in which the automation of the replacement of the barrier plate is easily performed, and in which further automation of replacement procedure, simplification of replacement procedure, and reduction of time required for replacement procedure are achieved is provided.
a by the turning of the ink fountain member 2 and turning the barrier plate in a direction away from the outer peripheral surface of the ink fountain roller 3, a moving body 88 capable of moving above the ink fountain 1 and being raised and lowered, and a barrier plate holding member 91 disposed in the moving body 88 to hold and release the barrier plate 53.
An ink container capable of automating the replenishment of ink to an inkpot and simplifying setup operations and reducing setup operation time by further automating the setup operations. The ink container (65) is characterized in that it is formed in a vertically compressible bellows shape, a slit closed normally is formed in a bottom wall (72), and when an upper part is pressed downward while a bottom part is held, a slit portion is opened by a pressure and the ink therein falls downward through the opened slit portion.

A printing machine capable of largely simplifying setup operations and reducing setup operation time by largely automating the setup operations. The printing machine comprises an inkpot member (2), an ink fountain roller (3), a band-like sheet (39) having an intermediate part applied to the inkpot member (2), a sheet moving device (40), a pair of edge-dams (53) sucked onto the inkpot member (2) through the sheet (39) and sucked onto the outer peripheral surface of the ink fountain roller (3) by a permanent magnet, an ink recovering tank (56), an ink scraping blade (57), a blade position selector device (58), an edge-dam changer (85), a plurality of ink containers (65) in which different types of inks are stored and which are stored in a container storage part (66), and an ink replenishing device (86) holding the specified one of the ink containers (65) and replenishing the ink in the container to an inkpot (1).
An ink transfer split roller unit capable of preventing an abnormality from occurring by detecting an abnormality in changing over the positions of ink transfer rollers. The ink transfer split roller (5) comprises a support member (6) fixed to the frame (7) of a printing machine, a plurality of short cylindrical movable members (8) mounted on the support member (6) so as to be reciprocatingly moved independent of each other in a same direction, the ink transfer rollers (15) rotatably mounted on the outer peripheries of the movable members (8), and a roller position changeover device (19) installed in the support member (6) and changing over the positions of the movable members (8) independent of each other. A position changeover detection sensor (102) for detecting the changeover of the positions of the movable members (6) is mounted at the portion of the support member (6) in slidable contact with the movable members (8).
A printing machine capable of automating the replenishment of ink from different types of ink containers to an inkpot and simplifying setup operations and reducing setup operation time by further automating the setup operations. The printing machine comprises an inkpot member (2) having an inkpot forming surface forming an inkpot (1), an ink fountain roller (3) capable of extruding the ink to the outer peripheral surface thereof through an ink passage in the clearance thereof from the inkpot member (2), a plurality of rollers (4, 15) feeding the ink extruded to the outer peripheral surface of the ink fountain roller (3) to a print portion, the plurality of ink containers (65) in which the different types of inks are stored and which are stored in a prescribed container storage part (66), and an ink replenishing device (86) holding the specified one of the ink containers (65) and replenishing the ink therein to the inkpot (1).
A printing machine capable of easily automating the replacement of edge-dams and simplifying setup operations and reducing setup operation time by further automating the setup operations. The printing machine comprises an inkpot member (2), an ink fountain roller (3), the pair of edge-dams (53) sucked onto the inkpot forming surface (37a) of the inkpot member (2) and the outer peripheral surface of the ink fountain roller (3) by a permanent magnet, and an edge-dam changer (85). The edge-dam changer (85) comprises an inkpot member rotating device (36), an edge-dam restraining member (110) restraining the edge-dams (53) moving apart from the inkpot forming surface (37a) by the rotation of the inkpot member (2) and rotated together with the ink fountain roller (3) and rotating the edge-dams in a direction for moving them apart from the outer peripheral surface of the ink fountain roller (3), a mobile body (88) movable and liftable over an inkpot (1), and an edge-dam holding member (91) fitted to the mobile body (88) to hold and release the edge-dams (53).
