はない。In the clavier printing, the paper wound on a roll is drawn out, and printing is carried out by the ink adhering to the surface of the plate cylinder through a space between the plate cylinder and the impression cylinder. A combination is needed. Therefore, one Clavia printing machine consists of a combination of many plate cylinders and impression cylinders arranged in a straight line, and in order to keep the overall length short, the space between cylinder combinations is narrow, and the part that goes out of the printing machine Is getting narrower. The plate cylinder must be replaced every time the printed material changes, but the replacement work in the space is not easy.

別形態の装置の発明が必要となった。In the conventional cylinder replacement work, two workers held both ends and carried the old and new edition cylinders for replacement, but since it is a tough, dirty, and dangerous work in a narrow space, the workers are fixed. Due to the poor performance, it was requested to install an unmanned exchange for the old and new bodies. However, since the old and new bodies are also placed upright because of the location, the invention of a device different from the above invention is required also from this point.

For each set, one unit is provided in the space between them, and one unit is rotated to allow the front and rear plate cylinders to be exchanged. The plate cylinder changer is provided with a first traversing device that moves at a right angle to the bogie rail on a bogie that moves on a rail laid at a right angle to the center line of the printing machine, on which a turning device for a vertical axis and a horizontal movement are provided. The vertical movement device provided via the second traverse device and the gripping device having two facing gripping plates are attached to the ends of the horizontal rotation shaft. Opposing grip plates expand and contract the space to grip and support the plate cylinder.

With the grip plate horizontal, stop towards the exchange cylinder. Here, the first traversing device and the second traversing device are actuated, and the gripping device is ejected close to the exchange cylinder. At the same time, since the air cylinder pressure is lowered to make it swing, the grip plate becomes floating,
Even if it hits the surface of the plate cylinder, by avoiding it easily, it will move along the surface of the plate cylinder without causing an impact, and the plate cylinder will be sandwiched from above and below by the gripping plate. The pressure rises when it is fully clamped, and the grip plate holds the plate cylinder securely from above and below.

Then, the carriage moves to the exit of the printing machine and stops, and the plate cylinder is pushed outward by the second traversing device and at the same time stands vertically by the rotating device. In that state, the first traverse device moves the rail at right angles to the rail to carry the old plate cylinder to a predetermined storage space, and if the gripping device is lowered and the grip plate is removed, the plate cylinder will stand in the predetermined storage space and be accommodated. Removal work is completed.

The motor pinion 1a attached to the truck 1 meshes with the rack 2a fixed to the rail 2,
The carriage 1 is moved in the space between the printing cylinders at right angles to the center line of the printing machine. On the upper surface of the truck 1, a first traverse device 3 is formed at right angles to the rail 2.
A dovetail-shaped rail 3a that slides with is laid and supports the turning device 4. A rail 5a is laid on the second traversing device 5 above the revolving device 4 to support the horizontal portion of the vertical moving device 6 by means of dovetail groove sliding. Further, a vertical rail 6a is fixed to the vertical portion of the vertical moving device 6, and a rotating device 7 is attached by dovetail groove sliding, thereby supporting the gripping device 8 at the tip of a shaft for horizontal rotation. The gripping device 8 is composed of two gripping plates 9 facing each other, and is capable of sandwiching and supporting the plate cylinder 10. Among the operations of the above parts, the linear movement is performed by an air cylinder, and in particular, the air cylinder for adjusting the distance between the vertical moving device 6 and the gripping device 8 and for adjusting the distance between the gripping plates 9 includes the swinging mechanism.

At the time of replacement, first, the carriage 1 moves into the space of the printing machine and automatically stops at the position shown by the thick solid line in FIG. Next, two sets of traverse devices 3 and 5
Is operated and the gripping device 8 is extended to the position of the plate cylinder 10.
Since the plate cylinder 10 has various thicknesses and the central height thereof is not constant, the opening and height of the grip plate 9 are roughly adjusted to the height of the plate cylinder in advance. Therefore, the gripping device 8 that has been pushed out enters the upper and lower sides of the plate cylinder 10 while adjusting the height of the gripping plate 9 by lowering the pressure of the air cylinder by the swinging mechanism, and when the gripping plate 9 is completely inserted, the gripping plate 9 is removed. Lock from the top and bottom.

As it is, the carriage 1 reaches the boundary of the printing press and stops.
Here, the gripping device 8 is put out of the printing machine, the plate cylinder 10 is rotated to be changed to a vertical position, and the plate cylinder 10 is further traversed to place the plate cylinder 10 in the predetermined storage space 11 shown in FIG. 2 to complete the work of removing the old plate cylinder.

In this case, however, the plate cylinder does not have a shaft, so it is difficult to hold and must be held directly by the arm. Paint and pigments adhere to the surface of the plate cylinder, so the clothes are very dirty, and since it is a manual work in a narrow space, it is extremely fatigued. Therefore, the worker did not last long and had a difficult time recruiting. The present invention solves the problem, keeps the workplace clean, and can reduce the number of personnel by 2 to contribute to cost reduction.
