The present invention relates to a printing plate positioning method and device for positioning, and a printing plate handling device for printing plate positioning.

[Prior Art] Printing plates (hereinafter referred to as "PS plates") used in newspaper presses, etc. are packed in a state where they are stacked on top of one another, placed on a printing plate handling device, and printed by a printing plate printing device. It is loaded into the plate handling device loading unit (hereinafter simply referred to as “loading unit”).

In the above packaging, the PS plates are stacked on a plurality of sheets, placed on a plate stand of a printing plate handling device (hereinafter simply referred to as “skid”), packed by a braid, and transported in this state. The skid is inserted into the loading section of the printing apparatus.

As shown in FIG. 5, a pair of rails 10 and 12 are arranged in the loading section of the printing apparatus, and the loading position of the PS plate in the loading direction (the direction of arrow A in the figure) is positioned on the upper surface of the rail 10. Blocks 14 and 16 to be performed are fixed. The block 14 is arranged on the front side in the insertion direction (the direction of arrow A), and the block 16 is arranged behind the insertion direction. Also rail 12
Mountain-shaped blocks 18 and 20 are fixed on the upper surface of. The block 18 is arranged on the front side of the rail 12 in the loading direction, and the block 20 is arranged on the rear side. Furthermore, a pair of compression coil springs 22 are arranged in the loading portion at the back in the insertion direction.

On the other hand, blocks 26, 28, 30, 32 corresponding to the blocks 14, 16, 18, 20 are fixed to the back surface side of the plate base 25 of the skid 24 as shown in FIG.

A plurality of PS plates are stacked and placed on a board 25 of the skid 24, lifted together with the skid 24 by a fork such as a hand lifter, transported to the loading section, and inserted.

In this loading, the skid 24 is inserted into the loading portion while being lifted by the forks, and the compression coil spring 22 is further pushed after the front portion of the plate base 25 comes into contact with the compression coil spring 22.
The block 26, 28, 30, 32 of the plate base 25 of the skid 24 is inserted into the block 14,
The PS plate is loaded into the loading section by lowering the hand lifter so that it is placed on 16, 18, and 20. Block 14,
Compression coil springs after being placed on 16, 18, 20
The plate base 25 is pushed back in the direction opposite to the loading direction by the urging force of 22,
The skid 24 is positioned in place.

In this case, the block should be positioned in the direction perpendicular to the insertion direction.
This is easily done by fitting 18 and block 30, and block 20 and block 32 together.

[Problems to be Solved by the Invention] However, when the PS plate is inserted into the loading section by the positioning device, the positioning method, and the skid used in the positioning apparatus described above, the plate base 25 is inserted when the skid 24 is inserted into the loading section.
It must be inserted against the urging force of the compression coil spring 22 that hits against, and force was required to insert the skid 24 into the loading section. For this reason, insertion into the loading section has not been easy. Therefore, it is conceivable to weaken the biasing force of the compression coil spring 22, but if the compression coil spring 22 is weakened, the force that pushes back the skid 24 to a predetermined position becomes weaker, so it is possible to load the PS plate at a predetermined position. There is a problem that you cannot do it.

Also, when inserting the skid 24 into the loading section,
Since the operator does not know the insertion amount while inserting the, the skid 24 is inserted too much into the loading section, or the skid 24 is lowered on the front side. It was bad.

Further, when the skid 24 on which the PS plate is placed is inserted into the loading section, there are cases in which a plurality of printing plates are overloaded. That is, if the insertion movement of the skid 24 into the loading section suddenly stops, the PS plate will shift due to inertial force. For this reason, when inserting and moving, it is necessary to slow down the moving speed just before stopping so that the PS plate does not shift, and the timing to slow down the moving speed is unknown because the amount of insertion is unknown. . Therefore, this work required skill.

In view of the above facts, the present invention is a printing plate positioning method that is easy to insert when loading a printing plate into a loading unit, can know the insertion amount, and does not cause the printing plate to lose its load.
