Title:
PRINTING PLATE CLAMPING DEVICE OF PRINTER AND OFFSET ROTARY PRINTER
Document Type and Number:
Japanese Patent JP2016093955
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To carry out the switch operation of a printing plate clamping state and an opening state of a printing plate clamping device without using a tool and compelling a large operational burden to an operator, even while improving fastening force for fastening a printing plate to a plate cylinder by the printing plate clamping device.SOLUTION: A printing plate clamping device of a printer winds a printing plate 2 having a gripping side end portion 2a and a gripping tail side end portion 2b formed so as to be bent on a back surface side to a plate cylinder 1 to be fixed. In a printing plate clamping state of a tension bar 5 in which the tension bar 5 winds and tightens the printing plate 2 around the plate cylinder 1, so as to centrifugal force generated in a tension bar rotation system 5S composed of a tension bar 5 and a lever member 7 integrally rotating with the tension bar 5 with rotations of the plate cylinder 1 act in a printing plate clamping direction to the tension bar 5, the gravity center Cof the tension bar rotation system 5S is set at a predetermined eccentric position to a rotation center Cof the tension bar 5.SELECTED DRAWING: Figure 6
