Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an apparatus for transporting and storing printing plates mounted on a rotary press for printing newspapers, etc. on a fixed shelf so that they can be easily taken out.

PRIOR TECHNOLOGY Various types of printing plates are suspended and conveyed by conveyance means such as a hanger conveyor, and are temporarily stored on a shelf before being loaded onto a rotary press, and the required type of printing plate is retrieved from the shelf. Although it is selectively taken out and installed in a rotary press, conventional examples of temporary storage shelves are as disclosed in Japanese Utility Model Application Publication No. 63-37669, in which it is first stored on a shelf. Since the printed printing plates must be taken out first, there is a drawback that the required types of printing plates cannot be taken out arbitrarily in any order.

That is, in the conventional example shown in FIG. 4, the printing plate P suspended by the hanger conveyor H is removed from the hanger, guided down by the chute G, held in a horizontal position by the support piece, and then transferred to the traverse conveyor. C, it was sent to a rotating shelf S that rotates endlessly in the vertical direction.

The carousel S has multiple trays T, and when the printing plate P carried in by the transverse conveyor C is loaded onto the toilet T, the tray T is lowered by the installation pitch of the tray T, and the next empty tray T is placed on the tray T. receives the next printing plate from the traverse conveyor C and moves down again by the mounting pitch.

In this way, a large number of trays T on the descending path
A printing plate P is loaded on each tray, and is taken out from the take-out port D at the lower end position of the descending path, and the empty tray T is reversed and enters the ascending path, and then reversed again and enters the loading and descending path.

Therefore, the printing plate P is moved from the loading position of the traverse conveyor C to the take-out port D on the descending path of the carousel S.
A large number of printing plates will be stored in the process.

Problems to be solved by the invention In the conventional example described above, the printing plate loading port is located at the top and the unloading port is located at the bottom, so the printing plate that is loaded first is taken out first, which is a disadvantage of the so-called first-in, first-out system. have.

That is, to take out the printing plates P, it is necessary to arbitrarily take out the necessary types of printing plates mounted on the rotary press at any time, so a storage shelf is required that can take out the printing plates in random order rather than on a first-in, first-out basis.

However, since the shelf shown in Fig. 4 is of a first-in, first-out type, if the plate that has descended to the outlet D is of an unnecessary type, if it is placed on the tray as it is, it will slide off the tray when the tray is turned over. Regardless of whether the type of printing plate is essential or unnecessary, it is necessary to take out the plates one by one from the outlet.

Therefore, if the type of plate taken out is not needed, it should be taken out but kept near the take-out port. However, when there are a large number of plates on hold, This has the drawback that it is no longer easy to find the required type of printing plate, and the work of installing printing plates on rotary presses is forced to stagnate.

Means for Solving the Problems Therefore, in order to solve the above-mentioned drawbacks of the conventional example, the present invention has been devised to take a printing plate that has been unloaded from a hanger conveyor, etc. and is held in a horizontal position by a support piece, and then reverts it to a hanging position. The plates are stored in a hanging position in parallel on each of the horizontal rods of a large number of hooks in a fixed storage shelf, and the stored printing plates can be taken out at will without being constrained by the order of first loading. A lifting locking plate that locks the plate in the horizontal position in a hanging position and lifts it up and down, and a plate that receives the plate in the hanging position in the hanging position and raises it above the fixed storage shelf. The plate is transferred from the plate to a horizontal hook rod in a fixed storage shelf, and then pushed into a predetermined storage position at the outlet using a pusher rod.

Function: The lifting locking plate, which is locked to the hook edge formed on the upper side of the printing plate in the horizontal position, rises to place the printing plate in a hanging position. When the storage rack is lowered, it is transferred to the temporary retaining locking piece, and then received by the lifting hanging hook of the lifting guide rod attached to the trolley that runs along the top surface of the fixed storage shelf, and by the lowering of the lifting hanging hook. The printing plates that were suspended from the claws are replaced with the selected hook crossbars in the fixed storage shelf.

Then, the printing plate transferred to the hook horizontal lever is slid on the hook horizontal lever by the printing plate pushing rod, and is stored and stored with the printing plate take-out side edge aligned regardless of the size of the printing plate width. .

Embodiment Figures 1 to 3 are schematic front views of the present invention, Figure 2 is an enlarged front view of the lifting guide rod, Figure 3 is a side view of Figure 2, and Figure 4 is an explanatory diagram of the conventional example. It is.

In Fig. 1, a printing plate 1 that has been suspended and conveyed by a hanger conveyor is unloaded from the hanger and slides down on a chute, and is then sent to a hanging standby stand 2 by a cross-feeding conveyor, and a plate is formed on the upper side of the printing plate. The edge of the hook is placed in a protruding position on the elevation path of the elevation locking piece 3.

Therefore, the elevating and lowering locking piece 3, which is rotatably attached to the mounting member 6 connected to the reciprocating endless chain 5 suspended in the column 4 and can be rotated by the motor M, rises from below along the column 4 and waits for hanging. After engaging the hook edge of the printing plate 1 on the stand 2 and hanging it as shown in the figure, it rotates 180 degrees by the operation of the motor M and descends along the support 4 to the lower end position of the support.

Below the pillar 4, there is a cross beam 7 as shown in FIG.
Temporary locking piece support member 8 fixed to is attached,
A pair of opposing temporary retaining locking pieces 9a and 9b are attached to the support member 8 so as to be movable forward and backward, and when the lifting locking piece 3 descends, it assumes a horizontal position. The temporarily received locking pieces 9a and 9b move forward on the descending path of the lifting locking piece 3 and wait, and the printing plate 1 hanging from the lifting locking piece 3 is moved to the temporary holding piece 9.
a, 9b, and then retreats out of the lowering path of the elevating locking piece 3.

The vertical locking piece 3 is rotated in the vertical direction by a cylinder 3'.

Therefore, the lifting locking pieces 3 are temporary locking pieces 9a, 9b.
It rises along the pillar 4 without interfering with the.

After the lifting locking piece 3 is raised, the cart 10 running on the cross beam 7 moves toward the temporary receiving locking pieces 9a, 9b, and the lifting guide attached to a slide cylinder or the like fixedly suspended from the cart 10 is moved. When the locking hanging pawl 12 that moves up and down while being guided by the rod 11 is located directly below the temporary receiving locking pieces 9a, 9b, the pair of temporary receiving locking pieces 9a, 9
b opens downward as shown in FIG. 3, and the printing plate 1, which had been suspended hanging from the temporary retaining locking pieces 9a and 9b, is replaced and locked by the hanging hanging claw 12.

The printing plate 1 suspended from the locking hanging claw 12 is received at a slight inclination by the steady plate 13 attached to the lifting guide rod 11.

Note that a pressing piece 12' that is lifted and lowered by a cylinder is attached above the locking hanging claw 12.
The hook edges of the printing plate are held down so that the printing plate suspended from the hook 12 does not come off the hook while descending.

A fixed storage shelf 14 having a plate loading opening on the upper surface is disposed below the lift guide rod 11. The storage shelf 14 is provided with a number of plate hanging storage hook horizontal rods 1.
The upper edge of the horizontal rod 15 is provided with a notch member 15a so that the locking hook 12 can be lowered without interfering with the horizontal rod 15 when the printing plate suspended by the locking hook 12 is transferred to the horizontal rod 15.
5' is provided.

Therefore, the printing plate 1 suspended from the locking hanging hook 12 is moved to a position directly above the desired horizontal hook rod 15 of the storage shelf 14 by the running of the cart 10, and then guided up and down by the operation of a slide cylinder or the like. It descends along the rod 11 and is replaced by the horizontal rod 15 of the plate suspension hook of the storage shelf 14, and the lifting guide rod 11 is moved away from the horizontal rod position of the hook due to the movement of the cart 10, and the locking hanging hook 12 is moved.
rises and returns to its original position.

A pushing cylinder 16 is installed horizontally at the lower end of the lifting guide rod 11, and an lifting cylinder 18 of the pushing rod 17 is vertically installed at the tip of the piston rod of the cylinder 16.

Therefore, the printing plate 1 suspended from the hook horizontal rod 15 is moved along the upper edge of the hook horizontal rod 15 by pushing the pushing rod 17, which has been lowered to the pushing position by the operation of the lifting cylinder 18, and by the operation of the cylinder 16. It is pushed towards the ejection port.

At this time, depending on the operating stroke length of the pushing cylinder 16, the pushing amount is small for a wide printing plate, and the pushing amount is large for a small width printing plate, so that the side edge of the printing plate at the printing plate take-out port of the storage shelf is You can arrange them.

Effects of the invention With this invention, the printing plates can be lowered from above and stored hanging in parallel to the storage shelves, which greatly reduces the floor space occupied compared to when printing plates are stored from the side of the storage shelves. In addition, regardless of the size of the printing plate width, the take-out side of the printing plates stored in the storage shelf can be aligned, so even small-width printing plates can be easily retrieved from the storage shelf by hand. It is something that can be taken out.
