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 bent upper side is hooked on the clipper H of the conveyor C and conveyed in a direction perpendicular to the drawing. This device is related to a continuous loading device for printing plates, which receives the completed printing plates from the plate making machine, hooks them onto the hook of the lifter, conveys them vertically, deposits them in the feed conveyor, and transfers them to the plate conveyor C for the next process. This is a device that automatically and continuously loads the clipper H in a timely manner.

An object of the present invention is to provide a printing plate loading device as described above that allows printing plates to be loaded smoothly onto a conveyor without damaging the printing plates.

According to the present invention, there is provided a conveyor belt for placing a printing plate taken out from a plate-making machine in a predetermined position so that one bent side projects from the side, and a lifting rail installed on the side of the conveyor belt. A hook is movably attached to the lid and hangs the printing plate by engaging the protruding bent side of the printing plate when the plate moves upward from the lower end of the lifting rail. an infeed conveyor movably mounted on a rail supported horizontally at a height, at one end of the rail, receiving the plate hanging from the hook when the lifter descends from the upper end of the elevating rail; a conveyor that is supported horizontally above the other end of the rail and has a clipper movably attached thereto that engages the bent portion of the upper side of the printing plate when the feed conveyor moves to the other end of the rail; There is.

Therefore, the printing plate taken out from the plate making machine is loaded onto a predetermined position by the conveyor belt so that one bent side projects from the side.

When the lifter moves upward along the lifting rail, a hook attached to the lifter engages the protruding bent side of the printing plate, and the printing plate is suspended by the hook and carried upward.

At this time, the infeed conveyor moves to one end of the rail and is located below the hook and printing plate.

When the lifter descends in this state, the printing plate is received by the feeding conveyor and removed from the hook.

The infeed conveyor having received the plate moves to the other end of the rail.

At approximately the same time, the clipper of the conveyor moves to a predetermined position and engages the upper bend of the printing plate.

Then, the clipper transports the printing plate along the conveyor while hooking the printing plate.

By repeating the above operations, the printing plates taken out from the plate making machine can be automatically and successively loaded onto the conveyor.

Embodiments of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 to 3, a belt conveyor 5 is installed on the side of the plate-making machine P.

A chain wheel 3 is attached to the play 4 of the belt conveyor 5,
A chain is stretched between a chain wheel 3 and a chain wheel 2 attached to a motor 1.

The printing plate F taken out from the plate making machine P is placed on the belt conveyor 5 with the bent side facing downward and parallel to the traveling direction.
It is designed so that it can be sent to

Further forward of the belt conveyor 5, a conveyance heald 10 is installed.

A chain wheel 8 is attached to the play 9 of the conveyor belt 10, and a chain is stretched between the chain wheel 8 and a chain wheel 7 attached to the motor 6.

The conveyor belt 10 receives the printing plate F from the belt conveyor 5 and sets the printing plate F at a predetermined position.

In this case, as shown in FIG.
It is positioned so that one bent side protrudes to the side of 0.

A lifter 17 is installed on the side of the conveyor belt 10.

The lifter 17 is moved horizontally by an air cylinder 19.
In the state shown in FIG. 3 in which the hook 18 which can be rotated by 0 degrees is supported and the lifter 17 is located at the lower end, the hook 1
8 is positioned below the bent side of the printing plate F that protrudes from the conveyor belt 10.

The lifter 17 is guided by a lifting rail 16 erected above, and is fixed to a chain 15 stretched along the lifting rail 16.

The chain 15 is stretched around a chain wheel 14 attached to the upper end of the lifting rail 16, and the chain wheel 13, which is attached coaxially with the chain wheel 14, is attached to the motor 11 via the chain. It is designed to be linked to the car 12.

A feed conveyor 22 is provided in the middle of the lifting rail 16, and the feed conveyor 22 is formed by bending the lower edge of a support plate having an inclined surface so as to support the printing plate F at the lower edge. It has become.

The feed conveyor 22 is slidably attached to a horizontally supported rail 21 and connected to an air cylinder 20, so that the feed conveyor 22 is moved on the rail 21 by the operation of the air cylinder 20.

Further, the rear end of the rail 21, that is, the air cylinder 20
A conveyor C is supported horizontally in a direction perpendicular to the rail 21 above the portion where the conveyor C is attached.

The clipper H attached to the conveyor C is adapted to engage the bent portion of the upper side of the printing plate F when the feed conveyor 22 retreats, as shown by the imaginary line in FIG.

In the above configuration, the printing plate F that comes out of the plate making machine P is first inspected for good or defective products on the belt conveyor 5, and if it is a good product, it is passed through and transferred to the next conveyor belt 10.
sent upwards.

When the printing plate F is placed on the conveyor belt 10, the lifter 17 is located at the lower end of the lifting rail 16, and the hook 18 of the lifter 1γ is positioned below the bent side of the conveyor belt 10 that protrudes to the side. are doing.

When the motor 11 is operated in this state and the lifter 17 is raised via the chain 15, the hook 18 engages with one bent side of the printing plate F, as shown by the imaginary line in FIG.
Gradually lift up the printing plate F and let it hang down.

When the lifter 17 reaches the upper limit position, the hook 18 is rotated 90 degrees by the air cylinder 19.

At this time, the feed conveyor 22 is located at the front end of the rail 21 and below the hook 18 and the printing plate F.

In this state, when the lifter 17 is lowered, the printing plate F is
It is introduced into the feed conveyor 22 and supported.

Then, the hook 18 from which the printing plate F has been removed turns 90 degrees and returns to the lower end of the lifting rail 16 together with the lifter 17.

The feed conveyor 22, which has received the printing plate F, is moved backward on the rail 21 by the operation of the air cylinder 20, and moves to the position shown by the imaginary line in FIG.

At this time, the clipper H of the conveyor C engages with the bent portion of the upper side of the printing plate F.

Then, the clipper H moves the printing plate F along the conveyor C with the printing plate F hooked thereon.

After the printing plate F is conveyed by the clipper H, the feed conveyor 22 is moved to the rail 2 again by the operation of the air cylinder 20.
Return to the front end of 1.

Hereinafter, by repeating this operation, the printing plate F from the plate making machine P is
are continuously loaded onto the conveyor C.

It should be noted that, instead of making the lifter 17 swingable in the horizontal direction, the same purpose can be easily achieved by arranging the feed conveyor 22 in the width direction of the printing plate F which is vertically suspended by the lifter.

As is clear from the above points, the present invention (1) carries out vertical conveyance, so it can be conveyed at a high place, requires less space for installation, and since the vertical conveyance is hooked, the printing plate will not be damaged.

(2) The feed conveyor should be placed on standby below the transport conveyor in advance, and the materials should be loaded in a timely manner without stopping the transport conveyor.

The practical benefits it brings are important.
