Description

TECHNICAL FIELD The present invention relates to a printing plate storage device mounted on a printing press such as a newspaper, and is suitable for storing various types of printing plates. .

2. Description of the Related Art Various types of printing plates that have been suspended and transported by a transporting means such as a hanger conveyor are temporarily suspended and stored in a fixed storage shelf before being mounted on a rotary press, and required from the storage shelf. This type of plate is selectively taken out and mounted on a rotary press. Such a plate storing and storing device was previously proposed as Japanese Patent Application No. 1-87443 as shown in FIG. There is.

That is, in the front view of the main part shown in FIG. 4, the traveling carriage A moving along the front surface of the fixed storage shelf S has a hanging edge portion H'for locking the upper hook edge of the plate 1. A suspension hanging plate H is hung, and a plate-feeding pushing piece P that reciprocates in a frame F attached to the hanging plate H along the hanging edge of the hanging plate H is provided. ing.

Therefore, when the traveling carriage A moves, the locking suspension plate H
The hanging edge H'of the same and the locking hanging metal fitting B'formed on the upper side of the selected one row of the vertical partition plate B suspended in multiple rows above the fixed storage rack S are aligned with each other. At this time, the plate feeding member P pushes the plate front side edge 1a toward the fixed storage shelf S side and locks the upper hook edge of the plate 1 from the hanging edge H'of the hanging plate to the vertical partition plate. The plate 1 is slid and transferred to the locking suspension metal fitting B'of FIG.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In the above-mentioned conventional technique, since the pushing piece P pushes the plate front side edge 1a and feeds it into the fixed storage shelf S, the plate front side fed into the fixed storage shelf S Although the edges 1a are aligned on a straight line, if the width of the printing plate 1 is large or small, the rear side edge 1b of the printing plate becomes uneven, and when the rear side edge 1b of the printing plate is manually removed, a small width Since the rear side edge 1b of the plate is deep inside the fixed storage side S and the hanging gap of the adjacent plate is small, it was extremely difficult to take out a small plate.

In order to solve the above-mentioned drawbacks of the prior art, the present invention aligns the rear side edge 1b of a small width printing plate with the rear side edge of a large width printing plate so that it can be suspended and taken out easily.

MEANS FOR SOLVING THE PROBLEMS The present invention is a printing plate for transferring a printing plate suspended from a plate locking suspension plate on a traveling carriage to a plate locking suspension metal fitting of a fixed storage shelf of the printing plate and pushing it. A two-stage telescopic cylinder device is provided along the reciprocating path of the feeding and pushing piece, and is attached to the tip of the cylinder device so as to be erected and erected so that the plate on the locking hanging metal fittings of the storage shelf is shelved. It is a plate press storage device with a plate press pusher attached to the back.

Operation After the plate feed push-in piece has been sent to the fixed storage shelf of the plate, the large plate is pushed to the predetermined hanging position by the extension of the first stage cylinder of the two-stage telescopic cylinder device, and the small plate is pushed. For the plate, the two-stage telescopic cylinder is extended to both stages,
It is pushed into a predetermined hanging position where the side edge after printing of a small width plate is aligned with the side edge after a large plate.

Embodiments FIGS. 1 to 3 show an embodiment of the present invention, FIG. 1 is a front view of a main part, FIG. 2 is a plan view of the main part of a two-stage telescopic cylinder device, and FIG.
The figure is a side view of the main part of the fixed storage shelf, and there are two types of printing plates for newspaper printing, a large printing plate of 4 pages and a small printing plate of 2 pages.

Plate locking on the traveling carriage The plate hanging on the hanging plate is transferred to the plate locking hanging metal fittings of the plate fixed storage shelf. Frame F attached to hanging plate H
It is attached to a reciprocating chain C that is endlessly suspended therein, and a two-stage telescopic cylinder device 2 shown in FIG. 2 is attached to the frame F below the reciprocating chain C.

As shown in FIG. 2, the two-stage telescopic cylinder device 2 has a first
It has a cylinder 2a and a second cylinder 2b connected to the piston rod of the first cylinder 2a, and a rising and urging plate presser pusher 3 which is erected upright is attached to the tip of the piston rod of the second cylinder 2b. Operating rod for pusher rod 3 '
2c is fixed, and the pusher rod 3'is slidably supported by a pair of bearings 4a, 4b attached to the frame F.

When the two-stage telescopic cylinder device 2 is contracted, the plate pushing pusher 3 collides with the rear side edge of the plate hanging plate H and falls down as shown in FIG. 2, and when extended, the hanging plate H is extended. The urging force of a coil spring or the like wound around the up-and-down shaft pin and standing up as shown by the chain line to push the rear side edge 1a of the printing plate and push the rear side edge 1a of the storage shelf. The plate that is suspended and suspended above is pushed into the back of the shelf.

Therefore, when the printing plate is fed by the pushing piece P attached to the chain, the cylinder device 2 is contracted, the pusher 3 is in the lying posture, and is retracted from the plate feeding path. The front side edge 1a of the plate is fed to the 1a 'position by being guided by the plate hanging edge H'and slidably transferred to the locking hanging metal fitting B'of the fixed storage shelf S without support.

When the printing plate 1 to be transferred has a large width, that is, a 4-page printing plate 1L, only the first cylinder 2a is extended to move the printing plate front side edge 1a at the 1a 'position to the 1a "position. Push in, plate 1
Is a small width, that is, the two-page plate 1S, the second cylinder 2b further extends and pushes the front edge 1a of the plate to the 1a position. ′
After printing, the side edges 1b of the printing plate are substantially flush with each other.

Effect of the Invention According to the present invention, after the printing plate is sent to the fixed storage shelf, the two-stage telescopic cylinder device is actuated to push the large width printing plate by extending only the first cylinder, and the small width printing plate to the first Since the pushing-in distance can be increased by the extension of the second cylinder, the rear edge 1b of the plate is substantially flush with the take-out port S'of the fixed storage shelf, and the plate can be taken out manually. The work is extremely easy to perform, and its practical effect is remarkable.
