[Detailed description of the invention] (Field of industrial application) The present invention is a printing plate transport device used for transporting thin synthetic resin or metal printing plates for newspaper printing from a transport device. Regarding improvements.

(Prior Art) In general, printing plates made with a plate-making machine are transferred to a trolley conveyor (overhead chain conveyor) by a carrying device disclosed in, for example, Japanese Utility Model Application No. 52-97101 or No. 52-97103. ) type of conveyance device, is held in a suspended state by the normally closed clamping mechanism of the conveyance device, and is conveyed toward the printing press. A chute is provided, and the printing plates that reach the chute slide down the chute depending on the open state of the holding mechanism of the conveying device and are accumulated at the lower part of the chute.

However, since the carrying-out device was constructed of a chute, although the structure was extremely simple, the printing plates were not properly stacked in a proper state and in a predetermined order.

For this reason, the operator who attaches the printing plates to the plate cylinder of the printing press has to select and extract the necessary printing plates from the accumulated printing plates, and this type of work is said to be extremely complicated. There was a problem.

A lowering mechanism is provided below the lowering mechanism to lower the printing plate that has been stopped in a substantially vertical state, and the lowering mechanism is provided to lower the descending printing plate in a substantially vertical state at predetermined intervals in the front and back directions. It is characterized by being constructed from a storage mechanism that can store an appropriate number of items so that they can be taken out from any direction.

(Function) The printing plate is conveyed in a hanging state with its upper part being clamped by the clamping mechanism of the conveyance device.

The conveyed printing plate is stopped at a predetermined position by the stopping mechanism, and the clamping mechanism of the conveying device is opened by the opening mechanism, and the clamping mechanism is released by moving away from the position.

The released printing plate is lowered in a substantially vertical state by a lowering mechanism.

The lowered printing plates are sequentially moved substantially horizontally in a substantially vertical state by a storage mechanism while leaving predetermined intervals in the front and back directions.

That is, in the storage mechanism, an appropriate number of printing plates are stored in a substantially vertical state at predetermined intervals in the front and back directions, and each printing plate can be taken out from its edge direction.

Therefore, the operator or robot who loads the printing plates onto the plate cylinder of the printing press can select the necessary one from among the appropriate number of printing plates stored in the storage mechanism.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

The drawing is a schematic side view showing the structure of a printing plate delivery device according to an embodiment of the present invention.

The printing plate delivery device 1 includes a stop mechanism 2, a lowering mechanism 3,
The storage mechanism 4 constitutes its main part.

The stopping mechanism 2 is capable of stopping the printing plate A, which has been transported in a hanging state by the transport device 50, at a predetermined position.

In this example, it is provided on a guide body 6 supported by a base body 5.

The guide body 6 includes an upper inclined plate 7 which gradually inclines to the left (left side in the drawing) as it goes downward, and is connected to the upper inclined plate 7 with a step to the right below this, and the lower part is bent vertically. lower inclined plate 8 and upper inclined plate 7
A front guide plate 9 is connected to the front side (rear side in the drawing) and can make the inclined printing plate A hang down; and a front guide plate 9 is connected to the rear side of the upper inclined plate 7 to make the printing plate hang down. A
and a rear guide plate 10 which can be tilted.

The stop mechanism 2 includes upper and lower bearings 11 provided on the front right side of the upper inclined plate 7 of the guide body 6, a support shaft 12 supported by the upper bearings 11, and upper inclined upper bearings attached above and below the bearings 11. It consists of a claw piece 13 that protrudes to the left side of the plate 7 and can come into contact with the front end of the printing plate A, and a fluid pressure cylinder 14 that is provided on the upper inclined plate 7 and can rotate a support shaft 12.

The conveyance device 50 is of the type of trolley conveyor (overhead chain conveyor), which consists of a trolley 51 installed in a building, a chain 52 guided by the trolley 52, and a chain 52 that rotates at appropriate intervals. The chain 52 is installed so as to rotate in the front direction (towards the back in the drawing).

Therefore, at the unloading position in the transport device 50,
An opening mechanism 54 that opens the clamping mechanism 53 and a guide mechanism 55 that guides the clamping mechanism 54 so that it does not swing in the left-right direction (left-right direction in the drawing) are provided.

The printing plate A is bent at both the upper and lower ends to form a bent part B,
C, and one bending part B is a conveying device 50.
It is designed to be held by a holding mechanism 53.

The lowering mechanism 3 is provided below the stopping mechanism 2 and is capable of lowering the stopped printing plate A in a substantially vertical state.

In this example, it is comprised of a lower inclined plate 8 of the guide body 6, and a chain conveyor 15 extending downward to the left side and parallel to the lower inclined plate 8 at a predetermined interval.

The chain conveyor 15 has upper and lower sprockets 16 and 17, and a chain 18 that spans these.
and an appropriate number (in this example, two) of receiving pieces 19 attached at predetermined intervals. Two sets of receiving pieces 19 are arranged spaced apart from each other in the front and rear. As the receiving piece 19 is synchronized, its right side is rotated to descend.

The lower inclined plate 8 of the guide body 6 is attached to the base body 5 by forming a slit or dividing it into parts so as not to interfere with the receiving pieces 19 of the front and rear chain conveyors 15.

The storage mechanism 4 is provided below the descending mechanism 3 and is capable of storing an appropriate number of descending printing plates A in a substantially vertical state at predetermined intervals in the front and back directions so that they can be taken out from the edge direction. be.

In this example, an upper chain conveyor 20 is supported by the base 5 and extends horizontally from below to the right side of the lower inclined plate 8 of the guide body 6, and an upper chain conveyor 20 is also supported by the base 5 and is spaced apart from below the upper chain conveyor 20. Lower chain conveyor 21 arranged parallel to the lever
It consists of.

The upper chain conveyor 20 has left and right sprockets 22 and 23, and a chain 2 that spans the sprockets 22 and 23.
There are two sets of chains 24 spaced apart from each other in the front and back.
The front side of an appropriate number of bars 25 extending in the front-rear direction are attached at predetermined intervals in a cantilevered manner.

The lower chain conveyor 21 has left and right sprockets 26 and 27, and a chain 2 that spans these.
Two sets of 8 are arranged spaced apart in the front and back,
The front and rear chains 28 have a long cross section approximately L in the front and rear direction.
Receivers 29 exhibiting a mold are spaced apart from each other by a bar 25 at predetermined intervals.
The same number of bridges have been constructed.

The lower and upper sides of the upper chain conveyor 20 and the lower chain conveyor 21 are rotated intermittently to the right in synchronization by a drive machine (not shown).

Next, the operation will be explained based on such a configuration.

The printing plate A is conveyed from the back to the front (from the front to the back in the drawing) in a hanging state with the upper end bent part B being held by the holding mechanism 53 of the conveying device 50 as shown by the dashed line in the drawing. .

The conveyed printing plate A is guided by the rear guide plate 10 of the guide body 6 so as to be gradually inclined, and reaches a carry-out position where the upper inclined plate 7 is located.

If the printing plate A is not carried out here, the opening mechanism 54 and the stopping mechanism 2 of the conveying device 50 do not operate.

Therefore, the printing plate A that has reached the upper inclined plate 7 is guided by the front guide plate 9 and is conveyed after changing from the inclined state to the hanging state.

When carrying out the printing plate A, the opening mechanism 54 is operated to open the clamping mechanism 53 as shown in the drawing, and the stop mechanism 2 is operated to cause the claw body 13 to protrude to the left side of the upper inclined plate 7. Accordingly, the printing plate A is stopped at a predetermined position.

Thereafter, the printing plate A slightly slides down along the upper inclined plate 7, but at this time, one of the receiving pieces 1 of the lowering mechanism 3
9 is located at the upper position, the lower end bent portion C comes into contact with this and is prevented from sliding down.

Then, when the clamping mechanism 53 leaves the unloading position, the printing plate A is completely released from the clamping mechanism 53.

The released printing plate A descends as the receiving piece 19 of the descending mechanism 3 that supports it descends, and in the middle of the movement, the upper end bent portion B touches the upper inclined plate 7 and the lower inclined plate 8. While touching each other, it descends in a leaning state as shown by the chain double-dashed line in the drawing.

Thus, the upper end bent portion B of the printing plate A is connected to the lower inclined plate 8.
When it comes off, it hooks on the bar 25 of the storage mechanism 4 waiting at this position, and then the lower bent portion C of the printing plate A comes off the receiving piece 19 of the lowering mechanism 3.

For this reason, the printing plate A is suspended vertically by the bar 25 of the storage mechanism 4.

Each time the printing plate A is sent to the storage mechanism 4,
It is intermittently moved to the right by the distance between the bars 25.

A receiver 29 that moves in synchronization with the bar 25 is located at the lower end bent portion C of the printing plate A, thereby preventing the printing plate A from swinging in the left-right direction.

In this way, the printing plates A are sequentially stored vertically in a well-ordered manner at predetermined intervals in the front and back directions.

To take out the printing plate A stored in the storage mechanism 4, grasp the rear edge of the printing plate A and pull it backward (toward the front in the drawing), and it will be guided by the cantilever bar 25 and extracted. I can do that.

Therefore, the operator or robot who loads the printing plates A onto the printing cylinder of the printing press can extract the necessary one from among the appropriate number of printing plates A stored in the storage mechanism 4.

Normally, one of the clamping mechanisms 53 of the conveyance device 50 includes:
Since two identical printing plates A are conveyed in a stacked manner, two stacked printing plates A are suspended and stored on each bar 25 of the storage mechanism 4.

In the previous embodiment, the stopping mechanism 2, the lowering mechanism 3, and the guide body 6 are tilted, but the present invention is not limited to this. For example, when the hanging plate A is stopped or lowered as it is, they can be tilted vertically. You can also make it into a state.

The receiving piece 19 of the chain conveyor 15 may be configured to be able to hold the printing plate A in a substantially vertical position.

In the previous embodiment, the storage mechanism 4 is arranged so that the printing plate A is in a vertical state, but the present invention is not limited to this. For example, the opposing positions of the bar 25 and the receiver 29 are shifted so that the printing plate A is in an inclined state. You can also do it like this.

Although the storage mechanism 4 was equipped with the lower chain conveyor 21 in the previous embodiment, the present invention is not limited to this, and for example, this may be omitted.

In the previous embodiment, the storage mechanism 4 is such that the upper chain conveyor 20 and the lower chain conveyor 21 each rotate around a horizontal axis, but the storage mechanism 4 is not limited to this, and may, for example, rotate around a vertical axis. or,
Alternatively, it may be something that rotates around a vertical axis like a turntable.

In the previous embodiment, the storage mechanism 4 is configured to move the printing plate A toward the rear.
However, the present invention is not limited to this, and it may be possible to extract forward or upward, for example.

In the previous embodiment, the storage mechanism 4 is connected to the upper end bent portion B of the printing plate A at the bar 25 of the upper chain conveyor 20.
However, the present invention is not limited to this. For example, the upper chain conveyor 20 may be omitted and the receiver 29 of the lower chain conveyor 21 may be suspended.
The plate A may be held in a substantially vertical position.

Although the guide body 5 was equipped with the front guide plate 9 in the previous embodiment, the guide body 5 is not limited to this, and may be omitted if, for example, the printing plate A is always carried out.

Although the printing plate A was provided with the bending portions B and C in the previous embodiment, the present invention is not limited to this, and the printing plate A may be, for example, without the bending portions B and C.

In the previous embodiment, the printing plates A are conveyed in sets of two,
