Description of the Related Art An outer peripheral portion of a plate cylinder of a printing press is provided with a notch having a substantially rectangular cross section over the entire length of the cylinder. In the notch, a plate (hereinafter, referred to as a plate) is held. A printing plate fixing device consisting of a vice on the side holding the side edge and a vice on the back side holding the edge on the side of the plate wound on the body circumference after being held by this It is fixed and extends in the trunk axis direction.

を行う。In such a printing press, when the specification of a printed material is changed and the plate is exchanged from the old plate to the new plate, the vice side of the plate is opened by rotating the cam shaft, and one end of the plate released from the grip is opened. Then, the old cylinder is removed by opening the vice on the grip side by rotating the cam shaft to release the other end of the plate from the grip. Thereafter, the new plate is mounted by repeating the opening and closing of the plate vise and the rotating operation of the plate cylinder in the same manner. Then, after attaching the printing plate to the recoil, move the vice applying the printing plate so that printing is performed at a predetermined position on the printing paper.
I do.

機構と、旧版と交換して版胴へ供給する新版を保持する
新版保持機構とを備えたものである。However, in this operation, the operation of rotating the cam shaft and the operation of rotating the plate cylinder must be performed manually or by operating a push button. In particular, it is laborious to hold the old and new plates by hand. Is extremely heavy and requires skill. In addition, the new plate cannot be prepared for mounting on the plate cylinder during printing work, and the old plate that has been removed must be removed out of the machine during plate replacement work. Productivity decreases. For this reason, the applicant of the present application has proposed an automatic plate changing device (plate holding device of a printing press) for easily changing plates in Japanese Patent Application No. 1-315380. This is an old plate holding mechanism that receives and holds the old plate discharged by opening the vise on the grip side and the rear side and rotating the plate cylinder, and a new plate that holds a new plate that is replaced with the old plate and supplied to the plate cylinder. And a holding mechanism.

When the force stops the plate cylinder at the position facing the leading end of the plate holding device, opens the gripper-side vise and the tail-side vise to release the grip of the old plate, and then rotates the plate cylinder approximately one turn. The old plate enters the plate holding device and is held. Then, when the plate cylinder is rotated and the new plate is pushed out with the holding plate vise facing the front end of the plate holding device, the plate vise closes and one end of the new plate is added to the plate vise. After turning the torso almost one turn,
Closing the other version vise ends the installation of the new version.

刷版を加えるようにしている。[0006] It is necessary to consider a printing machine provided with such an automatic plate changing device, and in recent years, it has become possible to perform registration using a remote controller. In the case of a printing machine equipped with an automatic plate changing device, when the plate cylinder automatically changes plates,
Even if the registration is performed by the remote controller, it returns to the reference position stored in advance, so that no vise adjustment is required. However, there is a limit to the registration of this device, and when registering beyond this amount, it is necessary to manually move the vise as before. In this case, in order not to automatically return to the reference position, the vise is returned to the reference position at the time of automatic plate exchange. When the printing plate is mounted on the plate cylinder, the reference pin provided on the vice is engaged with a hole (having an opening) provided at the edge of the printing plate, and then the vice is closed to print. I try to add a version.

The plate may be damaged. For this reason, the vise is returned to the reference position, and when the plate is automatically changed, the vice is returned to the reference position automatically, so the part where registration cannot be automatically performed manually. Sometimes, it is easy to forget to return the vise, so that the printing plate is easily damaged. In particular, when the operator is changed during printing work in three shifts, it is easy to determine whether or not the vise adjustment has been performed, and it is difficult to determine which unit has been operated in the multicolor machine.
