を高圧状態で使用する必要がある。On the other hand, a first actuator is provided on the upper end surface of the frame of the printing unit, and a link mechanism is provided between the first actuator and the lever of the cam shaft. A roller corresponding to the lever of the cam shaft is pivotally attached to the tip. By operating the first actuator to move the roller back and forth in the radial direction of the plate cylinder, the lever is swung to rotate the cam shaft,
As a result, the gripper plate is opened and closed with respect to the vise base, and the printing plate is gripped and released between the gripper plate and the vise base. Since a large force is required to reliably hold and release the plate, it is necessary to use the air pressure of the first actuator at a high pressure.

で使用する必要がある。Further, the frame of the printing unit is provided with a second actuator different from the above-mentioned first actuator. A link mechanism is connected to the rod of the second actuator, and a plate pressing roller opposed to the peripheral surface of the plate cylinder is pivotally attached to the tip of the link mechanism.
By operating this second actuator, the plate pressing roller is pressed against the peripheral surface of the plate cylinder. That is, the plate-holding roller holds the edge of the plate edge on the plate-neck side and then presses the plate against the peripheral surface of the plate cylinder, and further rotates the plate cylinder once to rotate the plate. Even when the plate is wound around the plate cylinder, the plate is pressed against the plate cylinder by the plate pressing roller to wind the plate in close contact with the plate cylinder. When the printing plate is wound around the plate cylinder, the pressing force of the plate pressing roller is set high so that the printing plate is brought into close contact with the peripheral surface of the plate cylinder. Therefore, when the printing plate is wound around the plate cylinder, it is necessary to use the air pressure of the second actuator in a high pressure state similarly to the first actuator.

た。Therefore, in the plate mounting apparatus of the conventional printing press described above, the solenoid valve of the first actuator and the solenoid valve of the second actuator are combined into one common air source. The structure is directly connected. Therefore, the operating pressure of the first actuator and the operating pressure of the second actuator are the same, and a high pressure is used. As described above, the plate pressing roller operated by the second actuator presses the peripheral surface of the plate cylinder with a large force even when the printing plate is wound around the peripheral surface of the plate cylinder. For this reason, during the work of winding the printing plate around the plate cylinder, it is necessary to be skilled and careful in the winding work in order to prevent part of the work clothes from being caught in the plate pressing roller and the peripheral surface of the plate cylinder. Since it is necessary to pay the cost, it is a complicated work, and the work takes time. It is also conceivable to reduce the operating pressure of both actuators before use, but the plate pressing roller does not adhere sufficiently to the peripheral surface of the plate cylinder, and the plate is misaligned and mounted on the peripheral surface of the plate cylinder. There was such a problem.

圧させる。In order to achieve this object, a plate mounting method for a printing press according to the present invention is designed to grip the edge of the plate on the plate side of the plate cylinder. At the initial stage of winding on the plate cylinder, the pressing force for pressing the plate on the plate cylinder is increased, and then the pressing force for pressing the plate on the plate cylinder is reduced.

力は低い。In step 4, when the start button 3 is pressed, the control device 2 drives the machine motor 5 and the plate cylinder 16 is thereby rotated, so that the old plate 36 is removed from the plate cylinder 16. Further, the pulse generator 6 sends a pulse signal to the timing device 7 in accordance with the rotation of the machine motor 5. The timing device 7 counts the number of pulses and sends a control signal to the controller 2 when counting a predetermined number of pulses. This control signal causes the control device 2 to stop the motor 5 of the machine, which causes the plate cylinder 16 to stop at a predetermined position for plate feeding. When the stop of the machine motor 5 is confirmed, the control device 2 sends a signal to open the solenoid valve 11 for attaching / detaching the plate pressing roller, so that the operating rod 27 is further retracted and the plate pressing roller 20 is indicated by a chain double-dashed line in FIG. The position shown, that is, the state of contact with the plate cylinder 16 is brought into contact. At this time, the plate presser roller pressure increasing solenoid valve 12 remains connected to the pressure reducing port 12b.
Since a reduced air pressure of BKg / cm 2 is supplied to the plate pressing actuator 26, the pressing force of the plate pressing roller 20 is low.
