Description

The present invention relates to a new proposal of a group management device for a plate making machine (hereinafter, simply referred to as “machine”) having a numerical control device.

In the platemaking workshop, many machines are equipped with a number of machines and operate them at the same time, but in the case of performing and managing work in this case, the actual situation is that there are major problems in the past. .

The present invention has been made to propose a solution to this problem, but in order to clarify the significance of the present invention, the problems currently present will be described in the following sections. I will.

(1) Problems from the viewpoint of efficient operation of individual machines.

First, the current operation mode of the machine will be described with reference to a plate making machine as an example.

For each machine (plate-making machine), the machine operator uses the numerical control devices attached to those machines to process data related to one unit work (that is, in the case of color printing, by performing overprinting, color printing is performed). Data for creating four color plates, "yellow plate", "red plate", "indigo plate", and "black plate", which are necessary for expressing Yes ”, or in the case of non-color printing, data for creating a black plate) is input.

On the other hand, a photographic original plate as a material to be processed (in the halftone image taking step, four photo original plates to be halftone images for each color plate are prepared for photography, and one of them is, for example, a yellow photo original plate) A raw plate material (an unexposed plate material on which an image is not printed) which is a material to be processed is also accurately positioned and attached to the original plate holder, respectively.

Then drive the machine.

Then, the image of the photo master for the yellow plate is printed on the plate surface according to the required allocation position by the automatic operation of the machine governed by the processing data input to the numerical control device described above (plate material surface). If four photo original images are printed on "4 sides", then "4 sides" or "4 sides", and similarly "6 sides", "6 sides", "8 sides", "8 sides""Etc), the machine stops working there.

Therefore, the machine operator separately prints the original plate for the yellow plate that has undergone the printing process and the plate material on which the image for yellow plate has been printed (the plate material on which the image has been printed is referred to as "press plate"). Remove from the machine, attach the next photo master plate (for example, red plate) and blank plate in the same manner as above, and restart the machine.

Then, by the same automatic operation of the machine that printed the image for the yellow plate, the image of the photographic original plate for the red plate was printed on the plate material, and then the indigo plate and the black plate were printed in the same manner. , The burning of one unit work is completed.

Machine operation is simplified to the point where the above procedure can be performed,
Automation has been achieved, and the work load on the machine operator has been significantly reduced.

By the way, in the plate making work, for example, in the case of multi-sided work which is one of the typical examples of the plate making work as described above, first, the work contents (processing time, work difficulty) for each unit work are very important. However, there is a special circumstance in the plate making work, that is, the work that has such variations in content is irregularly mixed in performing the work in the actual work. The points will be specifically described.

In the case of multi-sided, with four sides (which is rare 2
There are also impositions), so if there are many, there are 36 imprints, etc., and the number of printing surfaces is very wide.

Therefore, let's compare the cases of "4 pages", "16 pages", and "36 pages".

When the original plate holder is moved to the image printing position on the plate holder surface by the operation of the XY precision drive mechanism of the machine (plate-making machine), the image is printed by the automatic operation of the machine according to the following order. Done.

At that position, the photographic original plate is brought into close contact with the plate material surface by advancing a minute distance to the plate material holder surface of the original plate holder.

Vacuum contact between the original plate and the plate material by the operation of the vacuum contact mechanism of the stencil printing machine.

The exposure of the exposure lamp for the required time allows printing of the photographic original image on the plate surface.

 Release the vacuum contact between the original plate and the plate material.

A small distance of retreat from the plate holder surface of the original holder.

Needless to say, the above automatic operations (1) to (3) are performed for one color plate image (for example, yellow plate image) in one unit work.
And the number of operations required to print one surface.

Therefore, in the case of "4 sided", the total number of automatic operation of the machine is 80 times ("4 times because it has 4 sides" x "4 version << yellow version, red version, indigo version, black version >> “Times” × “number of operations 5”).

In addition, in the case of "with 16 pages", the total is 320 times ("16 times with 16 pages" x "4 times with 4 editions" x "number of operations 5").

Furthermore, in the case of "36 pages", the total is 720 times ("36 times because it has 36 pages" x "4 times because it is the 4th version" x "number of movements 5").

Thus, it can be seen that the difference in the number of printing surfaces causes a very large difference in the number of automatic operations of the machine.

That is, it goes without saying that this means that there is a large difference in the time required for the processing depending on the contents of one unit work.

It should be noted that these are comparisons about how many (one) imprint one photographic original image is printed on the plate material surface.
The actual situation of work processing in actual work is more complicated.

That is, in actual work, one photographic original image is printed on the plate surface (the number of pages is varied), and two are printed on the plate surface.
The work of printing three or more photo master images in a mixed manner (the number of impositions is various) is mixed irregularly.

An example of printing two or more photographic original images on a plate material is shown in FIG.

That is, the figure shows a case in which the image (A) and the image (B) are provided with a total of 8 surfaces, each having 4 surfaces. In this case, the image (A) is printed on 4 surfaces. Then, stop the machine, remove the photo master with the image (A) from the master, then attach the photo master with the image (B) to the master holder and restart the machine to restart the image (B). With 4 surfaces, even with the same 8 surfaces,
There is a big difference between the time and labor required for work processing when printing one photographic original image.

Summarizing the above description in one word, the contents of plate making work are diverse, and the time and labor required for processing for each plate making work is completely apt. It means that there is an unavoidable characteristic that there are various differences in size.

However, in the past, such a work that was completely inaccurate was individually assigned to each machine and the machine was operated, with this conventional method. Coupled with the fact that there are considerable individual differences in processing capacity, we aim to operate each machine efficiently,
It is extremely difficult to secure the most efficient work execution state of individual machine operators.

Therefore, in the conventional method of performing and managing multiple machines, which is an irrational method without any scientific basis,
As a matter of course, the work progress of individual machines varies, and frequently transparent operators and machines come out during working hours, resulting in extremely unsatisfactory results in operating the entire machine efficiently. In addition, it has become a decisive factor that hinders the work efficiency of the entire work site.

Furthermore, the fact that the conventional method does not provide any rationality for allocating the work to each machine allows the arbitrary intervention of the individual machine operator in the selection of the work. It is one of the factors that hinders the work efficiency of the entire workplace.

That is, in the above-mentioned work contents, the more the number of printing surfaces is, the longer the processing time required for one unit work is naturally, and the ratio of the time during which the machine is automatically operating is within that time. Get higher

From the standpoint of the machine operator, this means that if the photo original plate and plate material to be processed are attached to the machine and the machine is operated, the photo original plate and plate material will be dusted while monitoring the movement of the machine. You can have a lot of time if you pay attention to whether or not there is such a thing, in other words, this means that the work load is light and easy. The work that involves a lot of work and prints one image on the plate surface is given priority to win.

As a result, it leads to unsatisfactory facts such as improving the work efficiency of the entire work place and reducing the harmony between machine operators.

(2) Problems from the viewpoint of the degree of experience required of the machine operator.

As described above, when operating the machine: (a) Input of processing data for each unit work (b) It is necessary to attach the processed material to a predetermined position, but the operation (b) is extremely simple. The operator is not required to have a special degree of experience because the work is repeated, but for work (a), a special degree of experience is required because a special work element related to plate making work is required, and a large number of operators In a workplace that requires personnel,
Training operators is a heavy burden.

(3) Problems from the viewpoint of managing the operation results of each machine, and the results of each work, and the identification of the processing machine from the work results.

At present, as described above, each machine is automatically operated, and the work load on the machine operator is reduced.

However, since there is no means for automatically and mechanically recording and managing the processed data, individual machine operators will eventually be unable to record and manage the processed data for each machine. It has to rely on manual work, which means that there is a time loss for that and a factor that loses accuracy in the operation record management of each machine. It can be said that the management of machine operation results has a serious flaw in the accurate recording and accumulation of data, which is the basis for achieving efficient operation of individual machines and, in turn, efficient management, and at the same time, The time loss and labor costs associated with this work cannot be ignored.

Then, as described above, scientifically record the processed data,
Having no means to manage means that it is not possible to specify which of the machines and the processing date and time when there is a complaint from the client regarding the work results, or It takes a lot of time and labor for the specific work, so that it is not possible to respond promptly to the complaint, and it is not possible to accurately investigate the cause (machine malfunction, operation error, etc.) that leads to the complaint. Have problems such as.

(4) Problems from the perspective of managing the progress of work in the entire workplace.

Currently, there is no way to automatically and collectively manage the progress of work over time in the entire workplace, and it is absolutely impossible to scientifically achieve smooth and efficient work in the entire workplace. The reality is not.

The present invention has been made in order to solve the above-mentioned problems all at once.

That is, in the present invention; a group management device for a plate-making machine comprising a group management computer and a plurality of plate-making machines equipped with a numerical controller connected to the group management computer, wherein the group management computer Is the first processing data consisting of the input / stored processing data for each unit work and the processing order. First, based on the processing order, the processing data for each unit work is first sent to each plate making machine. Multiple plate-making by automatically distributing the processing data for each earliest unit work among the first unprocessed processing data based on the end signal of the one-unit work from each plate-making machine. Distribution means for automatically operating a machine for manufacturing, and a second section related to this automatic distribution
Of the plurality of plate-making machines, and a control means for calculating and outputting the operation results of the plurality of plate-making machines from the stored second process data. By devising a device, it is intended to solve the above-mentioned problems.

In the present invention, by devising the above group management device,
Based on the work completion signal from each machine from the group management computer, various data can be automatically distributed to each machine from the "first processing data" input to the group management computer. Therefore, the highest operating efficiency can be pursued for each individual machine.

That is, the present invention eliminates the irrationality and non-scientificity of the conventional method, which decisively impedes the efficient operation of individual machines when a plurality of machines are operated at the same time. In this case, the operating efficiency of individual machines will be drastically improved.

Further, according to the present invention, since the processing data is automatically distributed from the group management computer to the individual machines and is stored therein, it is possible to grasp the work progress of each machine with the group management computer. You can

Further, as described above, in the present invention, the fact that the means for distributing work to a plurality of machines has been fundamentally changed is freed from the standpoint of a machine operator, which is a complicated work of inputting process data. As a result, the machine operation can be simplified and the work efficiency can be improved, and it is possible to operate the machine without experience.

In addition, it is possible to retrieve the operation records of individual machines quickly and at any time by using the group management computer (second processing data). It is possible to deal with the above-mentioned problems accurately, and by taking out the operation record of each machine, it is possible to help further improve the efficiency.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is an overall configuration diagram of the device of the present invention. In FIG. 1, (1) and (2) show a floppy disk as an external storage device of a mini computer (3) as a group management computer. It is a disc.

Incidentally, the mini computer (3) is not shown because it is well known, but a central processing unit (CPU) and a ram (R
It goes without saying that it is composed of AM), ROM (ROM), hard disk, interface, etc.

And, by this mini computer (3), input and storage of the "first processing data" by the operation of the keyboard (6) described below, automatic distribution from the "first processing data" to each machine The storage of the processing data related to the automatic distribution (that is, the "second processing data"), and the identification of the processing machine and the operation record of each machine from the "second processing data" can be output by calling. It is made.

The processing data (see FIG. 2) for each unit work is recorded on the floppy disk (1), and the processing sequence (refer to FIG. 3) related to the processing data is recorded on the floppy disk (2). ·Store.

Therefore, first, regarding the recording / storing of the processed data for each unit work, the outline will be described with reference to FIG. 2 showing the screen display of the display device (4).

<< Version code JAP man 001 >> This is a headline to identify which one-unit work.

From the figure, it can be read that it is the processing data of one unit work with the number designated as "JAP man 001".

<< Pattern >> A printing operation pattern is shown.

In other words, it indicates in what order the images of the photographic original plate are printed on the printing material, in other words, in what movement pattern the original plate holder is moved along the hopper surface of the printing material.

It is specified by selecting from a separately provided "pattern table", and it can be read from the figure that "1" in the "pattern table" is specified.

For example, as shown in "FIG. 6", this pattern "1" has a photographic original image (8) on the plate material (P) and a pattern of 4 in the X direction.
When arranging 2 rows in the row and Y direction and "8 sides", as shown by the arrow, the leftmost photo original image in the lower row (8)
Start from the top frame, burn the bottom row to the right, and burn up to the top of the photo original image (8) in the rightmost row of the bottom row, then go straight up to the top row and the topmost right row. Showing the printing operation pattern in which the upper row is printed leftward from the frame of the photo original image (8) in the row and the image reaches the leftmost frame of the photo original image (8) in the upper row and ends. Is.

<< Register Mark >> The register mark (9) which is the registration mark is photographed around the photographic original image (8) in the photographic original plate (F) as shown in FIG. 7.

The registration marks (9) are printed as shown in FIG. 6 in the process of printing each photographic original image (8) from frame to frame by the automatic mask device provided in the plate holder, that is, the plate. The four masks, one on each side of the glass plate of the holder, which can move up and down, left and right, are automatically and selectively operated by the masks on the light-shielding side and the light-exposing side. It is realized by advancing and fixing to the part (8 ') and leaving another mask fully open).

In the figure, XY is specified as "3", but this is
As shown in FIG. 6, only the register marks (9) located outside the photographic original image (8) are designated to be printed (usually this way).

<< Line / Stage >> This is used to specify how many columns and how many stages the original photo images are arranged on the plate material.

In the drawing, X is designated as "4" and Y is designated as "2", which means the image layout mode shown in "Fig. 6", that is, the photographic original image (8) is arranged in four columns in the X direction. It can be read that designation has been made to print in the arrangement of two stages in the Y direction (that is, "8 sided" or "8 sided").

<< Feeding >> It shows the distance from the center to the center of adjacent images in the original photo images to be arranged.

From the figure, the X direction is from the center of adjacent images to the center.
It can be read that it is 200 mm and 300 mm in the Y direction.

<< Start Point >> In the case of the normal printing mode, as shown in the figure, "0", that is, no designation is necessary.

For example, when two types of photographic original images are edited into two groups and mixed and printed on one plate material, the start position of the image on the first side of one group is determined from the position calculated by the computer. This item is used when sliding in one direction.

<< Film size >> Indicates the size of the film. From the figure, the X direction is 20
It can be read that it is 0 mm and 300 mm in the Y direction.
It is the same as the numerical value of the "feed" verified above, and when it is the same as the feed pitch in this way, it is not necessary to specify it as shown in the figure.

<< Shift >> This is specified when it is necessary to shift the layout (printing) position of the entire photo master image to either the top, bottom, left, or right of the plate.

From the figure, it can be read that it is specified to shift 20 mm in the Y direction (lift 20 mm in the Y direction), but this is due to the "quay" of the printing machine, and it is 20 mm more than the position of the normal photographic original image. It is specified because it is necessary to provide a blank space on the lower side of the plate material (there is a necessity for this item because the width of the mullet varies considerably depending on the type of printing machine).

<< Dub >> This is specified when it is necessary to provide an extremely narrow band-shaped margin between images on the photographic original plate due to folding or cutting of the printed paper after printing.

From the figure, it can be read that it was specified that there should be a 10 mm gap in the X direction, but this is only in the X direction. ) (10) is specified.

<< Baking area >> From the figure, it can be read that X is 810 mm and Y is 600 mm. This means that in the case of X, there are 4 rows (200 mm x 4) of photographic original images with a length of 200 mm in the X direction. = 800 mm) and the dove (10) 10 mm, the total is 810 mm.
The original photo image with a length of 300 mm in the Y direction has two steps (300 mm
× 2 = 600 mm) means 600 mm.

<< Stop >> This is specified when it is necessary to stop the machine halfway during the printing operation of the photographic original image on one raw material.

"0402" in the figure indicates that the machine should be temporarily stopped when the printing position (frame in Fig. 6) corresponding to the fourth row in the X direction and the second row (upper row) in the Y direction is reached. It is specified.

This is used, for example, when a plurality of photographic original images are mixed and printed on a raw plate material, and is for temporarily stopping the machine at the printing position and replacing the photographic original plate. .

<< Jumpover >> This is used for printing in a special mode.

For example, as shown in the figure, there are four columns horizontally (in the X direction) and vertically (Y
Direction)) When performing a total of "8 sides" with 2 steps, the 4 rows in the lower row in the X direction print 4 colors, but the 4 rows in the upper row print 3 colors excluding the black plate It is used for etc.

<< Controlled Burning >> This is provided so that the printing paper can be specified in consideration of the fact that the printing paper is stretched by a very small amount due to the pressure of the winding cylinder in the printing process depending on the printing position of the photographic original image printed on the plate material.

From the figure, 0.5mm for the upper row of the 1st row and the upper row of the 4th row
You can read that it is specified that the printing position is shifted by 0.4 mm each.

Next, regarding the processing data for each unit work, an example of which is shown in FIG. 2, regarding the recording / storing of the processing order thereof, based on FIG. 3 showing the screen display on the display device (4). An overview will be given.

In the figure, looking at the column of “version code JAP man 001” which is the processing data for one unit work shown in FIG.
The data is designated as "Reservation NO: 1" and "Temporary NO: 90".
It can be read that "1" is added and that the machine with "machine NO: 01" is designated (reserved) for processing.

In addition, [16 times] is specified in the [Number of times] item of the data, and the printing work of the four-color plate, which is one unit work, is performed in four times.
It can be read that it is specified to repeat once (4 sets of 4 plates are made).

In addition, "0808" is specified in the "Front / Back" item, which means that the printed matter is printed on the front and back sides, so it is printed eight times as a front side (a set of four plates 2 sets), and the backing is designated 8 times (2 sets of printing plates for one set of 4 sheets).

Returning to FIG. 1, the explanation will be continued.

A floppy disk in which the "first processing data" has been input and stored.
The discs (1) and (2) can be mounted on the floppy disc mounting portion of the mini computer (3) and a predetermined key operation can be performed by the keyboard (6) to display the "first processing data" on the display device ( It can be displayed on the screen of FIG. 4) (FIGS. 2 and 3) or can be printed and recorded by the printer (5).

The mini computer (3) includes machines such as a stencil printer, an automatic register mark marking machine, and a flat printing machine (M ₁ , M ₂ , M ₃ , M ₄ ...
..) are individually connected via the modem (7), and the floppy disks (1) and (2) are connected to the floppy disk.
When the mini computer (3) is started to operate on the disk mounting portion, the "first processing data", that is, the processing data for each unit work stored in the floppy disk (1), is stored in the floppy disk. The processing data related to the first unit work is sent from the mini computer (3) to each machine (M) in accordance with the processing order stored in the disk (2).

Based on the same processing data, the operator of each machine (M) performs only the above work (B) to perform machine operation, which causes any machine to finish the first unit work. Then (when the first working end is assumed to be a machine "M _2"), the signal (request signal and send the following processing data), mini-computer via a modem (7) from the machine (M ₂₎ Informed to (3).

By this signal, from the mini computer (3),
The earliest processed data among the unfed “first processed data” is sent to the machine (M ₂ ).

Then, if the machine (M ₁ ) finishes the first unit work following the machine (M ₂ ), the signal is immediately sent from the machine (M ₁ ) to the mini computer (3), The mini computer (3) also sends the earliest processed data out of the “first processed data” that has not been sent yet to the machine (M ₁ ).

Do the same for other machines (M ₃ , M ₄ ...)
Since the earliest processing data from the "first processing data" that has not been fed yet is sent with the completion of the one-unit work, the operator of each machine (M) automatically performs the processing every time the one-unit work is completed. Based on the processing data that is sent, the above work (b)
You can simply repeat.

As described above, the present invention has immeasurable effects on the work simplification of individual machine operations, and furthermore, the individual machine (M) from the end of one unit work to the next one unit work. Since the work is allocated while thoroughly eliminating the time loss, the operating efficiency of each individual machine can be maximized, and this greatly contributes to the work efficiency of the entire workplace.

Further, according to the present invention, since the machine operation is simplified as described above, the troubles concerning operator training can be solved at once.

In addition, as described above, the "first processing data" is
The processing data automatically distributed from the computer (3) to the individual machines (M) are stored and organized one by one in the mini computer (3) (ie, “second
"Processing data" is created at any time), and if a predetermined key operation is performed on the keyboard (6), for example, an individual processing record can be called within an arbitrarily determined time (period) for each individual machine. Etc. are accurately and quickly made by the "second processed data".

Fig. 4 shows a case where the processing record is called from the "second processing data" stored in the mini computer (3) by a predetermined operation of the keyboard (6) on the display (4). Has been done.

That is, in the figure, "Machine N" on July 10, 1984
It shows that the operation (intermediate) performance of "o.1" was output and displayed on the screen.

If you look at this, as the operation record related to one unit work with the "version code JPA man 001" of the first work,
The machine started operating at 9:30 and finished operating at 9:48, and it was confirmed that the number of times it had been printed was 16 times. In addition, in the next work, “version code JPA Otoko 050 It can be confirmed that, as the operation record related to the one-unit work marked with “,” the operation was started at 9:55 and ended at 10:01, and the number of printings was 4.

Although FIG. 4 shows the case where the screen is displayed on the display device (4), it goes without saying that it is also possible to print and record with the printer (5).

As described above, according to the present invention, since it is possible to freely manage the operation record of individual machines and the operation record of the entire machine, it is possible to respond promptly and accurately to complaints and the like regarding work results. It is possible to precisely manage the operation results of the machine, and the practical effect is great.
