Description

DETAILED DESCRIPTION OF THE INVENTION In recent years, technological reforms have been active to automate various mechanical devices and save labor, and various attempts have been made to achieve this goal, with the plate making industry being no exception.

However, these efforts are now bearing fruit, albeit gradually.

In accordance with the same purpose, the present applicant first used a single machine to carry out three operations: scribing register marks on the plate surface, pasting the film original, and printing the image of the film original. Developed an automated device that made it possible to implement the system (Patent Application No. 58-29080
Jitsugan No. 58-125216).

This device can perform three operations as described above, but the present invention can perform three operations as described below.
This is related to the proposal of a plate supply/discharge device that is extremely effective when this device is used for scribing work for register marks. Add an explanation assuming that the person will turn around.

According to this device (hereinafter, this device will be referred to as a "plate material processing device" to distinguish it from the device of the present invention); The operator simply inputs position and other data (hereinafter referred to as "processing data") into the attached operation command unit (computer), and then leans the plate against the plate support, which can freely set the tilt angle. The rest is done automatically: (a) Positioning of the plate material.

(b) Punching pin holes into the plate material using a punch mechanism.

(c) Forcibly removing the punch block that covers the edge of the plate surface to the outside of the plate surface (or forcibly moving the plate material out of the area occupied by the punch block).

(d) Locking and fixing the plate material to the plate material support surface.

(e) Register mark marking work.

(F) Releasing the fixation of the plate material from the plate support surface.

Since this process is performed continuously, the operator only has to take out the processed plate material from the plate support stand, which significantly reduces the workload on the operator.

Therefore, in the present invention, by further proposing an automated device for supplying and discharging plates to and from the plate processing device, the human work involved in scribing register marks on the plate surface can be reduced. This will reduce the burden to the utmost.

That is, the operator stacks the plates on the plate feeding table of the automatic plate supply/discharge device of the present invention according to the processing order, and inputs processing data for each plate material to the operation command unit according to the processing order. However, if you start operation at that point, (a) Supply of plates from the plate table to the plate processing device.

(b) Performing the intended work (writing register marks on the plate surface) in the plate processing device.

(c) Discharging the plate material from the plate processing device to the plate table.

is repeatedly and automatically performed, that is, the plates to be processed are stacked in advance on the plate feeding stand according to the processing order, and the processing data of each of these plates is input to the operation command unit according to the processing order. Once the system is set up, continuous and repeated operations can be performed without requiring any human intervention, making it possible to realize a so-called unmanned device.

The basic motivation for proposing the present invention is to propose an automatic plate feeding/discharging device that is particularly effective for the previous plate material processing device proposed by the present applicant, thereby significantly increasing the effectiveness of the use of the plate material processing device. (to enable unmanned operation), the present invention is designed with the following points in mind.

In other words, the actual situation regarding printing work in a single workshop is that the number of manuscript images laid out on the plate surface and the manner in which they are laid out are so diverse that it can be said that there are infinite variations, but the size of the plate used Also in terms of A size,
The reality is that it is not uniform for A full size, A half size, etc.

This means that in the automatic plate supply/discharge device, several types of plate materials of different sizes must be prepared on the plate feeding table.

Therefore, in the present invention, in order to accurately meet this request, a plate feeding table is constructed which is equipped with a desired number of plate material supporting walls, and this plate feeding table and a plate material processing apparatus perform necessary processing (plate material surface). First of all, it saves space by integrating a plate discharge table for temporarily storing the plate material that has been marked (registration and marking work) until it is sent to the next printing process. The specific structure of this is an integrated plate feeding table and plate discharging table, that is, a plate feeding table and a plate discharging table integrated.
It is configured to be rotatable around a vertical axis, and is rotated by the required amount to form the desired plate support wall (a surface on which a plate of a desired size is propped up, or a surface on which a processed plate is propped up). By simply arranging the plates in the correct orientation, it is possible to supply plates of the desired size to the plate processing device or to receive processed plates. The plate material holding frame can be moved by using an arbitrary drive means to enable the movement of the plate supply/discharge table and the plate processing device so that the plate holding frame can be placed facing them. In addition, the plate material to be processed can be suction-held from the plate supply/discharge table and delivered to the plate processing device, and the processed plate material can be suction-held from the plate material processing device and delivered to the plate supply/discharge table. It is.

Four printing plate support walls 10 with 0 are provided.

The angle of inclination of the plate support wall 10 is preferably the same as the plane of the plate support 20 of the plate processing device 2.

The plate feeding and discharging table 1 configured as described above has a wall surface for separating the plates to be processed by size and leaning them on the plate support wall 10, and for exclusively leaning only the processed plates. Secure one side and lean the processed plate material against it.

This is what is indicated on the top surface as A times, A full, A half, and discharge.
10b shows a double A size plate, 10b a full A size, 10c a half size plate, and 10d a processed plate.

This plate supply/discharge table 1 is fixed to a rotating shaft 30 which is rotatably supported and erected on the frame 3, and rotates integrally with the rotating shaft 30.

A chain sprocket 31 is attached to the rotating shaft 30, and the chain sprocket 3
1 and a chain sprocket 33 which is pivoted on the rotating core shaft of a motor 32 installed in the underframe 3. Therefore, when the motor 32 is rotated, This is transmitted from the chain sprocket 33 to the chain 34 to the chain sprocket 31, and the rotary shaft 30 and the plate supply/discharge table 1 rotate integrally therewith.

Locking pins 35 are retractably attached to required locations on the underframe 3, and on the other hand, each plate support wall 10a to 10 is attached to the chain sprocket 31.
Locking holes 36 are drilled at positions corresponding to d, and by rotating the motor 32 by the required amount and arranging the desired plate support wall 10 in the desired direction (on the front), the locking holes 36 can be opened. Since the locking hole 36 corresponding to the support wall 10 is located directly above the pin 35, the locking pin 35 can be inserted there.
(Although not shown, extending and retracting the locking pin can be easily configured by employing well-known means (air cylinder, etc.)), the locking pin can be extended and pulled back. pin 3
5 is fitted into the locking hole 36 (FIG. 2 shows the same state), and the plate supply/discharge table 1 is completely fixed with the desired plate support wall 10 arranged in the desired direction.

Next, reference numeral 4 denotes a substantially L-shaped plate material holding frame, and the plate material holding frame 4 is arranged in front of the plate material processing device 2 and the plate supply/discharge table 1, which are arranged side by side. It is slidably attached 40 to the guide fence 5, and
One end is attached 41 to a piston rod 61 of an air cylinder 60 erected on a moving frame 6 that is slidably attached to a guide fence 5.
The inclination angle is changed by the stroke of the piston rod 61 (raised by the stroke).

That is, if the piston rod 61 is retracted from the illustrated state (the piston rod is extended), the plate holding frame 4 will be raised as shown by the dotted line in the figure, and the plate holding frame 4 will be raised. Feeding and discharging plate stand 1
It is kept waiting in front of the board so that it does not become an obstacle when the board 1 is rotated.

The movable frame 6 is slidably attached to the guide fence 5, and is hung from a chain sprocket 70 pivotally attached to the rotating core shaft of the motor 7 and a chain sprocket 71 provided on the other side. It is fixed to the 72a side of the chain 72, and when the motor 7 is rotated and the chain 72 is run, the movable frame 6 is carried by the chain 72a and reciprocated between the plate processing device 2 and the plate supply/discharge table 1. The plate holding frame 4 also moves integrally.

A required number of suction tools 8 as shown in detail in FIG. 3 are attached to the plate holding frame 4, so that the plate can be freely attracted (and released).

To describe this in more detail, the suction tool 8 is constructed by attaching a suction cup body 82 connected to a vacuum pump (not shown) to the tip of a piston rod 81 of an air cylinder 80. For example, the piston rod 81 is hollow and functions as an intake passage 83 that communicates a suction cup 82 attached to the tip of the piston rod with the vacuum pump.

Therefore, regarding the same suction tool 8, first, the air cylinder 80 is operated to move the piston rod 81 on the suction cup 8 that is in light contact with the plate material or with an extremely small gap. If the vacuum pump is activated by stretching it out and pressing it against the surface of the printing plate, a vacuum action will be applied to the suction cup body 82 through the suction passage 83, and the plate material will be held against the suction cup body 82 and suctioned. Hold. It is.

The functions and effects of the present invention having the above configuration will be described in detail below.

First, four plate material support walls 10a to 1 are prepared in advance.
Regarding 0d, it is determined in advance which side to place the plate material of which size and which surface to put the processed plate material on, and this data is used as basic data for the automatic plate feeding and discharging device of the present invention and the plate material. It is stored in an attached operation command unit (computer) together with data related to the operation order of each component of the material processing apparatus.

Therefore, data related to the content of the work to be carried out from now on, that is, the processing order of each plate material and the size of each plate material (since the data is stored as described above, this will inevitably result in the processing of each plate material) Support wall 1
0 is selected) to the operation command unit (along with this, the plate material processing device also
The user inputs necessary data such as the writing position of register marks for each plate material, and accordingly, predetermined plate materials are propped up on each of the plate support walls 10a to 10c.

After the above operations are completed, an operation start signal is given to the automatic plate feeding and discharging apparatus of the present invention and the plate material processing apparatus 2.

Assuming that the sizes of the plates to be hung on each of the plate material support walls 10a to 10d are as shown in FIG. Since the wall 10b is placed horizontally to the left, the operation command unit first needs to lock the locking pin 35 fitted into the locking hole 36 in order to make the plate supply/discharge table 1 rotatable. A lock release command is issued, and the lock on the plate loading/unloading table 1 is released.Hereinafter, the members corresponding to the operation commands continuously issued from the operation command unit will be numbered and sequentially described, and the operations of each member accordingly.
