Description

[Detailed description of the invention] Recently, flexible thin printing plates made of synthetic resin have come to be used for printing newspapers, etc.

As shown in Fig. 4, this printing plate F is bent at the top and bottom by nearly 180 degrees, and the folded upper side is hooked on the clipper H of the conveyor C and conveyed in a direction perpendicular to the drawing. This invention relates to a continuous unloading device for printing plates.

According to the present invention, there is provided a transport conveyor on which a clipper which is arranged horizontally and is movably attached to hook the upper edge bent portion of the printing plate, and a guide attached below the transport conveyor that can freely appear and retract. a stopper that is attached to the plate and engages with the side of the printing plate to prevent the printing plate from moving; a chute disposed along the chute; a chain attached with a hook disposed along the chute for supporting the lower side of the printing plate removed from the clipper by the stopper and lowering the hook along the chute; a claw that is attached to a predetermined position of the chute so as to be freely retractable and that engages with the bent portion of the upper edge of the printing plate that descends along the chute to support the printing plate in a predetermined position; A stock shelf is installed on the side of the chute and has a plurality of rotatably attached blades extending radially in the horizontal direction, and a printing plate supported at a predetermined position on the chute by the claws is inserted into the blades of the stock shelf. It is equipped with a button.

Therefore, the printing plate is hooked by the clipper at the upper edge fold and is moved by the conveyor.

In the middle of the path, the sides are stopped by a stopper, and only the clipper moves and the printing plate is removed from the clipper.

At this time, the printing plate is located at the top of the chute, and its lower side is supported by a stopper attached to a chain.

Then, the chain rotates, the stopper descends, and the printing plate descends along the chute.

In the middle of the path, the bent portion of the upper edge of the printing plate is caught by a claw protruding from the chute surface, and the printing plate is supported at a predetermined position on the chute.

At this time, one blade of the stock shelf is located on the side in the extending direction of the folded portion of the upper edge of the printing plate.

Then, the other side of the printing plate is pushed by the pusher, and the printing plate is inserted into the blade of the stock shelf.

When the insertion of the printing plates is completed, the blades of the stock shelf rotate by a predetermined angle, and the next blade is located on the side in the extending direction of the upper edge bent portion of the next printing plate.

In this way, printing plates can be automatically inserted one after another into the blades of the stock shelf, allowing a large number of printing plates to be stocked in a small space.

The details of the embodiment having the stock shelves 14 in two upper and lower levels will be explained below with reference to the drawings. In FIGS. The bent portion of the upper side of the plate F is hooked and the plate is suspended and conveyed in the direction of the printing plate, that is, in the direction perpendicular to the second drawing.

The stopper 2 has a button that projects in a direction to prevent the printing plate F from advancing, and is movable in the direction of the arrow by the air cylinder 1.

Reference numeral 16 denotes a guide, and the printing plate F slides on the surface of the guide 16 and is conveyed to an intermediate position between the left and right stock shelves 14, and when the printing plate F comes to the center line, the front end of the width is stopped by a stopper 2. After only the conveyor C has passed, the pressed plate F is ready to descend along the chute 12.

On the other hand, a chain wheel 6 set on the same axis is driven by a chain wheel 4VC attached to a motor 3 via a chain wheel 5, and a chain wheel 7 suspended on the chain wheel 6 attaches hooks 8 at regular intervals.

This hook 8 serves to unload the remaining printing plate F downward along the chute 12.

There are also air cylinders 9 at two locations in the middle of the chute 12, and as shown in FIG. 5, the plate hooking claws 11 are pushed outward via levers 10.

The printing plate F caught on the claw 11 is pushed into the stock shelf 15 by the pusher 18 and is suspended from it, but the radial grouping of these wings 15 is directly connected to the motor output shaft directly connected below. Every time 11 printing plates enter, it rotates one pitch and all the printing plates are accumulated in the stock shelf 14 in sequence.

Now, the printing plate F, which has been slid and conveyed along the guide 16 by the conveyor C, is released from the clipper H and is moved to the stopper 2.
It is squeezed and left behind on the hook 8 of the hook conveyor chain 7, where it is carried downward.

As soon as the lower end of the printing plate F passes the first plate hooking pawl 11, the air cylinder 9 is actuated to push out the pawl 11, the front end of the printing plate is hooked on the pawl 11, and fixed in position. Press the side of the printing plate and push it between the blades 15 of the stock shelf 14.

The stock shelf 14 each time rotates by the included angle of the blade 14 to receive the next printing plate F, and the stock shaft 14 is rotated by the number of blades 15 in each case.
It is accommodated in

The stock shelf 15 has two levels, upper and lower, and when one is full, the claws 11 and pushers 13 on the lower layer have the same effect on one side, allowing the stock to be accumulated on the lower stock shelf 14.

According to the above-mentioned structure, the present invention naturally exhibits the following advantages.

In other words, (1) the printing plate is conveyed while being gripped by a clipper, and it is natural for the printing plate carried by the conveyor to stop and be crushed and left behind on the hook conveyor;
In addition, since the plate is held in place by the fixed catch claw, there is no confusion about the position when pushing it onto the shelf, and there is no risk of damage throughout the entire process.

(2) Since it is almost vertically unloaded, it requires less installation space, and the stock shelf is of a swivel type, so it is possible to store a large number of stocks, and since it is folded in the shape of an umbrella, there are few restrictions on the take-out direction.

A practical convenience such as a dog is a dog.
