At this time, as shown in FIG. 6, the cam 38 has its small-diameter portion 38a in contact with the vise base 35 to release the vise base 35 from being pressed, and the vise base 35 and the gripper plate 36. However, the elastic forces of the compression coil springs 42, 45 and 46 cause the support shaft 33 to be tilted in opposite directions with respect to the center. Then, after inserting the bent portion of the plate between the holding surface 35a of the vise base 35 and the holding surface 36a of the holding plate 36, the end 38 of the cam 38 protruding from the bearer 34 is inserted.
When a spanner is applied to c to rotate it, the cam 38 rotates and its large-diameter portion 38b begins to come into contact with the vise base 35 as shown in FIG. The vise base 35 and the holding plate 36 stand upright against the elastic force of the compression coil springs 45 and 46 and hold the bent portion of the plate. Further, when the cam 38 continues to rotate and the vise base 35 is pushed by the large diameter portion 38b, at the end of the rotation of the cam 38, the vise base 35 and the gripper plate 36 are integrated to form a compression coil spring. Since it moves in the circumferential direction of the plate cylinder 1 against the resilience of 42, 45, 46, the plate is stretched and adheres closely to the peripheral surface of the plate cylinder 1. At this time, the spring shaft 44 is pushed and a gap is formed between the double nut 43 and the spring receiving bar 31. In this way, the gripping and tensioning of the plate can be continuously performed only by rotating the cam 38.

And the plate is loosened, the double nut 43 comes into contact with the spring receiving bar 31, and then the small diameter portion 38a of the cam 38 comes into contact with the vise base 35, the elastic force of the compression coil spring 46 causes As shown in FIG. 6, the vise base 35 and the grip plate 36 are tilted to release the grip of the plate. Therefore, after rotating the plate cylinder 1 about 1 turn to release the winding of the plate, the cam shaft 19 is rotated to bring the large diameter portion of the plate gripping cam 20 into contact with the gripping plate 14. 14 opens, the other end of the plate is released, and the work of removing the plate is completed. In this way, the gripping and releasing of both ends of the plate and the tensioning and loosening of the plate can be performed by rotating the cam shaft at one position.

なる。As is apparent from the above description, according to the present invention, in the plate vise device of the printing machine, the bottom side plate vise that is located in the cylinder notch and holds one end of the plate is a plate that holds the folded end of the plate. It is composed of a vise table having a gripping surface and a gripping plate, and the vise table is movably supported in a plate cutout in a plate tensioning direction and a plate loosening direction, and always biases the plate in a loosening direction. At the same time, the vise base and the gripper plate are contacted in the direction of movement of the vise base so that they are swingably engaged and are constantly urged in a direction to release the gripper of the plate, and the gripper plate of the vise base is paired. By supporting the cam with the cam surface facing the surface opposite to the contacting surface on the body, the butt plate vice clamps the plate and the grip, and the grip release and loosening of the plate Since it can be performed continuously just by rotating it, the preparation time is shortened,
Productivity is improved and labor is reduced. Furthermore, by supporting the cam on the cylinder, even if the vise base moves due to the rotation of the cam, the center position of the cam does not move with respect to the cylinder and keeps the same position. It is possible to switch easily even if it is done by automation.

の発生が防止される。In addition, since the vise base and the gripper plate are in contact with each other in the moving direction of the vise base, the plate gripped by the plate gripping surface at the initial stage of cam rotation causes the plate to become tense at the final stage of cam rotation. For this reason, when moving the vise base and the gripper integrally, the cam further presses the vise base toward the gripper plate as the vise base moves, further increasing the gripping force on the plate gripping surface. As a result, the occurrence of slipping or loosening on the plate holding surface is prevented.
