There are the following problems. 1. The plate changing operation is a dangerous operation, and is avoided by workers. 2. The plate changing operation is performed in a small place. Therefore, the operator must perform this operation in an unreasonable posture. 3. The plate exchange operation is a loss time called a print preparation time. 4. The new plate needs to be positioned and mounted on the plate cylinder with high precision, and the mounting operation requires skill. 5. In the system of "plate changing device in sheet-fed printing press" described in JP-A-61-248834, a cassette also serves as a protective cover for a printing unit, so that the water level of the plate surface during printing is reduced. This is an obstacle when checking visually. Further, the structure is complicated.

The cassette in which the new plate is stored is slid downward by a drive device such as a motor upon receiving the plate exchange signal. At the lowermost position, the old plate butt is first discharged from the vice on the butt side of the plate cylinder. The ejected old plate bottom is bitten by a biting device and pulled into the cassette. At this time, the plate cylinder rotates in a direction to rewind the plate in synchronization with the drawing speed. When the removal of the old plate is completed, the cassette feeds the new plate tip between the upper and lower teeth on the bite side vice of the plate cylinder by the new plate feeding device.

静止する。When the tip of the new plate is clamped to the bite-side vise of the plate cylinder, the plate cylinder rotates in a manner to wind the plate. The plate exchange may be automatically completed by a series of operations, or the cassette may be stationary at the lower position during the plate exchange. As soon as the plate exchange is completed, the cassette slides upward and stops at the standby position.

The cassette is provided with a cassette supporting member which slidably supports the cassette between a standby position above the printing unit or the paper discharging unit and a plate changing position on the side of the printing unit. At the plate changing position, the old plate is first drawn into the cassette. The cassette is stored, then the new plate is mounted on the plate cylinder, and then the cassette is returned to the standby position.Therefore, the cassette is located between the standby position above the print unit or the discharge unit and the side of the print unit. Since it is moved between the two positions with the plate exchange position, the moving time is shortened, the operating efficiency of the printing press is improved, and the moving mechanism is simplified, and the cassette standby position is located at the upper part of the printing unit or at the paper discharge position. Since the unit is located at the top, the scaffold can be used in front of the unit, making it possible to prepare for plate replacement even during operation of the printing press, and to perform plate replacement work in a comfortable posture by yourself. It has the effect.
