2. Description of the Related Art Recent stencil printing machines use a stencil for mesh printing called a stencil master in the form of a perforated original. This plate-making master is wound on a hollow cylindrical stainless steel plate (plate cylinder) with perforated holes in a honeycomb shape, and a fine mesh-shaped cloth (screen) is wrapped around it. Do. FIG. 6 is a diagram showing the steps of stencil making and printing in stencil printing. First, in the plate making process (FIG. 6A), the original 30 is scanned while being illuminated by the lamp 31, the image data is captured by the CCD line sensor 32 into the personal computer 33, and the image data is transferred to the thermal head 34 of the thermal printer. Is used to melt and melt the resin in the ink-applied portion of the plate making master 22, and make a hole in the plate making master 22 as in the original.

[0003] A finer cloth screen is wound around the surface of the hollow cylindrical stainless plate cylinder 36 having the above-mentioned honeycomb-shaped perforations. The plate making master 22 after the plate making is mounted in close contact with the cloth screen. As shown in FIG. 6B, at the portion where the plate cylinder 36 contacts the printing paper 25, the plate cylinder 36 and the press roller 24 are in line contact with each other so as to sandwich the platemaking master 22 and the printing paper 25. Be placed. Further, an ink roller 23 is disposed in the plate cylinder so as to be in contact with the inner peripheral surface of the plate cylinder, and although not shown, the ink container is positioned inside the plate cylinder so that its spout is located at the ink roller 23. To be loaded. In this state, when the plate cylinder 36 rotates, the ink roller 23 pushes ink from the inside of the plate cylinder 36 and passes through the through-hole of the plate cylinder and the mesh of the cloth screen.
, And the original pattern is transferred to the printing paper 25.

The printing paper 25 after printing is dried to form a product by drying the ink, and the used plate-making master 22 is stored in a plate-discharge box (not shown). In the above, the plate-making master (plate) is obtained by sticking a thermoplastic resin film on thin Japanese paper so as to make the permeation of ink uniform. A material obtained by emulsifying oil in water is used for the printing ink, and a pigment is mixed with the base oil. The ease with which the master can pass ink and the ability to penetrate paper,
Since various characteristics such as temperature characteristics are required, a large number of ink types exist.

[0005] Unlike stencil printing such as PPC or ink jet printing machine (IJP), such stencil printing does not operate without both ink and plate-making master. In addition, high quality printing results can be obtained by setting the ink and the plate-making master in the correct combination in the printing press.
The types of ink and plate-making masters are very large, and differ from one printing press model to another, and even the same model may have different ink compositions depending on the destination region. If used in different combinations, not only will the desired printing result not be obtained, but in rare cases the plate will become clogged,
It may cause trouble. At present, there is no other way than reading the model number of a product to determine whether or not such an ink and plate-making master are the proper combination, and it is possible to use an inappropriate ink / plate-making master combination. Many.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described first with reference to a stencil printing machine system of the present invention. The stencil printing press system according to the present invention has a general configuration of a printing mechanism and a mechanical device itself which are not different from those of a normal stencil printing press, and an identification for checking whether a combination of an ink container and a stencil master is compatible. A medium and a reading device, that is, a non-contact data carrier and a non-contact data carrier reader are provided.

FIG. 1 is a diagram for explaining a stencil printing machine system. The printing press frame 40 has a hollow cylindrical plate cylinder 3
6 is installed so as to face the press roller 24 in parallel. As described above, the plate cylinder 36 is made of a stainless steel plate having a perforated hole in a honeycomb shape, and a substrate having a certain thickness that can withstand printing pressure and external pressure is used. A thin mesh cloth 36m made of silk, Tetron (registered trademark) or metal is wound around the peripheral surface of the plate cylinder. On the peripheral surface of the plate cylinder, a plate making master mounting portion 35 for mounting both ends of the plate making master 22 is provided.

The peripheral surface of the cylindrical plate cylinder 36 has an annular ring (not shown) provided on the frame at both ends.
Although the surface is rotated, the inside of the plate cylinder is configured to be non-rotating, and the ink roller 23 and the ink container 21 are loaded therein. The ink is supplied to the ink roller from the ink container outlet 21d. Although one or several ink rollers are provided, in the case of FIG. 1, two ink rollers are employed. The printing paper 25 receives the printing pressure and passes between the plate cylinder 36 and the press roller 24, so that the ink is transferred to the paper surface.

The antenna 16A of the non-contact data carrier reader 15 is located close to the side of the ink container 21 where the non-contact data carrier 211 is installed. The antenna 17A for reading the non-contact data carrier 221 of the plate making master 22 is installed at a position close to the outer peripheral surface of the plate cylinder 36 separately from the ink container. The close position is a distance in which non-contact communication is possible, and is usually a distance of about 1 to several cm. However, when the non-contact data carrier is mounted so as to read only one of the ink container 21 and the plate-making master 22, the antenna may be installed only at a position where one of the non-contact data carriers is read.

The main body of the non-contact data carrier reader 15, that is, the read signal is transmitted to the antennas 16A and 17A.
The circuit portion 15 for sending data to the printer or searching for and controlling received data can be installed separately from the antenna portion at a fixed position such as a frame portion of a stencil printing machine. The non-contact data carrier reader may have only a reading function and no writing function. That is, although a non-contact data carrier reader is suitable for the purpose of the present system, as described later, data may be written, so that it is preferable to have a writing function. When the stencil printing machine is a multi-color printing machine, units having such a mechanism are arranged in series in the printing direction.

In this state, when the ink container 21 and the plate making master 22 are mounted and operated, a preliminary operation (printing start) is performed.
At times, the antennas 16A and 17A of the non-contact data carrier reader / writer 15 of the stencil printing machine
Contactless data carrier 21 of both master 1 and plate making master 22
The compatibility is determined by reading the data of 1,221. In addition, even during normal printing, the amount of ink in the ink container is monitored for a decrease in the amount of ink and a change in environmental temperature, and necessary measures are taken.

The control unit of the non-contact data carrier reader 15 stores a combination table for judging the compatibility between the ink container and the plate making master. If the combination table does not match the matching list of the table, for example, a buzzer or the like is used. Issue a warning. The warning may also be displayed as “suitable” if they match, or “unsuitable” if they do not match. Also,
In the case of multi-color printing, a combination (color management information) of the color tone of the ink filled in the ink container and the printing color of the plate making master is also exchanged.

In the case where the non-contact data carrier is mounted on only one of the ink container 21 and the plate making master 22 as in the second aspect of the present invention, the non-contact data carrier is specified by the part number of the ink container or the plate making master. Is input to the non-contact data carrier reader / writer 15 ′,
Compatibility is determined by comparing the input data with data read from a non-contact data carrier of either the ink container or the plate making master.

<Regarding Ink Container> Next, the ink container will be described. The ink container is not particularly limited to a material, and may be a container formed of a solvent-resistant plastic material, a metal material, a bag-in-carton ink container, or the like. Non-contact data carriers can also be used for any material, such as when printing an antenna pattern directly on the ink container surface with conductive ink, or attaching a non-contact data carrier label, or plastic molding It is also possible to integrally mold a non-contact data carrier label or an on-chip coil type non-contact data carrier. In the case of a metal ink container, a fixed thickness (0.1 mm) may be provided between the non-contact data carrier and the metal container body.
If a dielectric layer (about 2.0 mm) is provided, there is no obstacle to communication.

At present, a commonly used ink container is a bag-in-carton type ink container, and an example thereof will be described below. FIG. 2 is a diagram showing a state in which a non-contact data carrier is provided in a bag-in-carton ink container. The ink container 21 is formed by attaching a solvent-resistant pouch 213 having a spout 21d to the inside of an outer carton 212 having a certain degree of hardness, and is integrally formed with the spout 21d from one end of the carton. Is to be peeped. A stencil printing ink is filled in a pouch (a portion indicated by a chain line in FIG. 2) 213. The non-contact data carrier 211 may be mounted on the outer surface of the carton or on the pouch surface in the carton. Pouch 2
13 is silica-deposited polyethylene terephthalate (P
A laminated material such as a laminated material composed of ET) / nylon (Ny) / polyethylene (PE) is used.

When the plug of the spout 21d of the ink container is taken out and loaded into the printing press, and printing is started, the ink is gradually supplied from the spout 21d to the printing press. The ink flowing out of the ink container is kneaded with one or several rotating ink rollers to have a uniform film thickness so as to uniformly adhere to the plate cylinder. ) Surface, and then passes through a cloth screen and a plate-making master to transfer to printing paper for printing. When a new ink container is set, a fixed amount of ink is filled. Therefore, if the amount of ink is recorded on the non-contact data carrier, the amount is read by the non-contact data carrier reader 15. If the ink container to be set uses the remaining ink used last time, the remaining ink amount is measured and written to the non-contact data carrier reader / writer 15 '. Therefore, in that case, it is preferable to provide the writing function as described above.

FIG. 2 shows a non-contact data carrier 211.
Are provided substantially at the center of the side surface of the outer carton 212. In this case, the contactless data carrier 211
A non-contact data carrier 211 is formed by mounting an IC chip with memory 21C on an antenna pattern 21A formed by directly printing on a carton base material. The antenna pattern is often used in the case where a winding pattern is formed on a dedicated base material of a non-contact data carrier using a metal foil (aluminum, copper, or the like) or the like, but as shown in FIG. Antenna pattern 21 of simple shape directly with conductive ink
Even if A is printed, it works well.

As the conductive ink, an ink for offset, gravure or silk screen printing using a carbon pigment, aluminum powder or the like can be used. The shape of the antenna is not particularly limited, and may be a linear shape or a wound shape, or may be two wings as shown in the figure. A bump is provided on the back surface at a position close to the wing pattern, and the function of a non-contact data carrier is achieved by mounting a tack-processed IC chip 21C.

The non-contact data carrier is not limited to the embodiment shown in FIG. 2, but a dedicated non-contact data carrier obtained by tacking and labeling is simply attached to the outer carton 212 with a labeler or the like. It may be worn. Further, it may be formed integrally with a plastic container. FIG. 3 is a diagram illustrating an example in which a non-contact data carrier is provided in a molded ink container. When the ink container 21 is formed by plastic molding, as shown in FIG.
L or an on-chip coil type non-contact data carrier to be described later may be loaded in a mold and integrally molded. The molding method can be injection molding, vacuum pressure molding, blow molding, or the like.

<Plate Making Master> Next, the plate making master will be described. The original stencil sheet for stencil was a base paper obtained by applying wax to Japanese paper, and the wax was removed with an iron brush and gully plate to form a portion through which ink passed.
Modern plate-making masters use a special hot-melt resin or a photosensitive resin to form a thin film or a thin film on a thin cloth such as Teflon (registered trademark) woven in tough Japanese paper or mesh. Laminated ones are used. In the case of the hot-melt resin, while illuminating the original as described above, the image of the original is taken in as data, and the thermal head of the thermal printer is scanned in synchronization with the image, so that the color tone of the image An ink passage portion having a size corresponding to the shading is formed in a mesh shape. The stencil ink is transferred to the printing paper through the mesh portion.

FIG. 4 is a diagram showing an example of a non-contact data carrier mounted on a plate making master. In the case of FIG. 4, the non-contact data carrier label 221L is attached to the plate making master 22 at the mounting end 22E. In addition, although it is illustrated as being attached to the outer surface side of the plate making master, the inner side may be used. The non-contact data carrier 221 is usually provided in a portion other than the region where the print image of the plate making master is formed. The master making master 22
Since a larger size than the printing paper is used, the stencil printing machine is located at the upper and lower ends of the stencil master (generally referred to as "holding" or "holding butt") or the left and right ends in an area where no pattern is formed. It is appropriate to provide it at a portion not shielded by the plate making master mounting mechanism. However, when the plate making master mounting mechanism is made of a plastic material, since the electromagnetic wave is not shielded, it may be a portion which is substantially invisible. In FIG. 4, an opening 229 is a hole for mounting the stencil master on a stencil printing machine. When a paper tube or a plastic tube is used for the mounting portion of the plate making master, a non-contact data carrier can be mounted on these tubes.

<On-Chip Type Non-Contact Data Carrier> FIG. 5 is a diagram showing an on-chip coil type non-contact data carrier. On-chip coil 12
An antenna coil 122 is formed on a silicon substrate 120 having a size of about 3 to 5 mm square, and both ends of the antenna coil 122 are electrically connected to an integrated circuit unit with memory 121 formed on the same substrate. The on-chip coil 12 is housed in a box. As a result, an LC resonance circuit is formed to resonate with a radio wave of a certain frequency to enable non-contact communication. In the present invention, such an on-chip coil 12
Is also included in the range of the non-contact data carrier because it can communicate with the non-contact data carrier reader / writer and transmit and receive data. With such an on-chip coil, it is difficult to secure a long communication distance, but it has a sufficient function when reading and writing almost in close contact with a non-contact data carrier reader / writer.

The attachment of the non-contact data carrier to the ink container or the plate-making master is not limited to in-mold molding, but may be performed by other ordinary methods, for example, using an adhesive.
The non-contact data carrier may be tack-sealed and affixed to the inner surface of an ink container or the like.

<About Input Information of Non-Contact Data Carrier> The following information can be input to the non-contact data carrier of the ink container. (1) Product name (character string), (2) Manufacturer name (code), (3) Target printer model name (character string), (4) Ink filling amount (numerical value), (5) Production date (year / time),
(6) lot number (character string), (7) ink type (character string), (8) color management information (character string),
(9) Temperature coefficient (character string), (10) Collection history (from / when), (11) Refill amount (character string), (12) Refill location (character string), and the like.

Based on such information, it is possible to detect the filling amount, perform temperature compensation, and exchange color management information in the case of color printing. Also,
In response to increasing environmental issues, information such as the recycling history, refill amount, and refill location when the ink container is recycled can be exchanged. In the case of recycling, ink may be filled in containers that are no longer suitable for use or incompatible containers, or printing may not be suitable if used without replacing consumable parts. And by recording the number of uses. further,
By mounting the "non-contact data carrier" on the plate making master side, it is possible to correct for variations in plate making conditions, and conversely, it is possible to adjust plate making conditions according to the type of ink.

In a contactless data carrier, generally, 12
5 kHz, 13.56 MHz, 2.45 GHz, 5.8
Since the frequency is in the GHz (microwave) band, an appropriate frequency band is selected and used. Depending on the type of data carrier to be used, the antenna can be selected from “electromagnetic induction type”, “electromagnetic coupling type”, “electrostatic coupling type” or the like, or can be used in combination. Compared with the case where a barcode is used, the positional accuracy with respect to the reading device is not required. The reading device can be downsized. That is, only the antenna (a rod-shaped antenna) may be provided at a close position. The advantages are that reading is not affected even if the data carrier is stained with ink, and that the bar code cannot be rewritten but the non-contact data carrier can be rewritten any number of times.
