Note that the printing machine referred to here refers to a printing machine or a textile printing machine.

The present invention relates to a multi-color printing or multi-coating printing apparatus which utilizes a plurality of printing machines and intermediate drying devices which are interconnected and arranged in sequence.

'l￥Keigi (・11) A drying device for drying printed stamps is known. An example of a conventional drying device is a drying device that uses a warm air flow. There is a device that uses a nozzle that directs the air to the printed +AH, and the flow of warm air dries the wet print and eliminates the evaporation that is generated when the print is dried.

It is also known to dry wet impressions on sheets of material by means of generating ultraviolet light, so-called UV radiation, said radiation curing the impression imparted to the fourth material. Typically, the printing ink or base used is made particularly sensitive to such radiation;
It should be reacted with this and dried. It is likewise known to dry an imprint applied to a material by means of generating infrared, so-called IR radiation, the radiation curing the imprint applied to the material. When applying printing ink or base, it is appropriate to select a printing ink or base that is particularly sensitive to the 1R radiation line and is dried or geared under its influence.

Naturally, especially to solve a particular problem, to the sheet of material 1;
Other types of drying stations and apparatus are known which are configured to effectively dry wet prints.

In conjunction with the drying station, there is a special air supply that ensures that the air in the drying station retains the desired humidity.
It is also known to take steps to remove moisture from steam during the drying process by passing an air-humidifier through the material.

The inks may be printed with different colors of ink, and the printing may be in the form of an electrically conductive paste or liquid, or an electrically insulating paste or body. The stamp is further soldered.

In the following description, J old n+ coating (coa
``tink'' is used as a general term to include all types of applications described above as well as motes not previously described.

TECHNICAL PROBLEMS One important technical problem with drying stations of already known construction is that the stations are usually used for thick prints or thick materials; Because of its size, the energy consumed by the station and the human power required to power the station are always very high.

However, the actual print surface can have a very controlled length and the coating can be made very thin, reducing the energy and power consumption of the drying station to that required for small print areas and or thin print coatings. The difficulty of adapting is being experienced.

Therefore, in a drying station, the problem of making the station usable with high energy and power requirements is of a highly technical nature.

There is also a major problem in creating a situation where the energy consumption is adjusted to the minimum possible value for a given trade-off with a given coating size and thickness.

In addition, multi-ink printing or Marziko T-ink printing-J equipment includes a plurality of interconnected, sequentially arranged printing machines, each printing machine corresponding to a particular ink or coating. Furthermore, when intermediate drying devices are provided, the energy consumed in each drying device is extremely large, and at the same time the total amount of space in the longitudinal direction is limited by the number of different notes to be imprinted on the material. The length of the complete 14-feeding device, the number of complete printing machines, the complete drying device, the other full printing machines, and the length of the other complete drying devices is determined by the number of J rollers, and therefore the number of printing machines required. There is a drawback that it is equivalent to total tears.In addition to this, the length of space required for the device to take out the old 1 is also a problem.

Therefore, the total length of space required for such a full maru-ink printing or multi-ink printing device is 4.

Solution The present invention mainly relates to a device for drying printed materials, and the device preferably has a material conveyance path, and the conveyance path preferably passes the material through a drying station to dry it, and further , having one or more print drying or print curing means.

In particular, but not exclusively, the invention is constructed such that the print drying or print curing means act intermittently, and the control means for controlling said intermittent action is adapted to act intermittently on said material. Coating/drying/kissing.

The present invention relates to an apparatus configured to actuate the means for drying or curing the imprint during a period of time which is arranged in close proximity to the sealing means.

According to one particular embodiment of the invention, the drying or curing means are in the form of a lamp, the lamp preferably emitting infrared radiation.

The lamp is a mercury lamp controlled by a control means having a choke and an igniter, and at t3. It's L'.

The control means ignites the lamp with at least one intermittent sequence of action, the ignition time being sufficient to maintain the ignition switch directly closing the lamp switch when the lamp switch f- is opened. It is the length.

The control means turn on the lamp ((

It has been found to be particularly advantageous to control the control means by means of a printing sheath which is closely connected to the drying device in the -L stream.

The drying device is equipped with a table forming a support for said month 1, and the surface of the table has a plurality of holes that interact with the secondary 1-E power source and the pressurized air source. During the drying or curing period, the table is connected to a secondary power source and holds the material R against the table L, and for the remainder of the time the table is connected to a source of pressurized air to remove the material from said table. Hold it two times.

With the aim of trading energy, according to the invention, the level of energy released per unit of time is selected for coating skin curing. The present invention relates to a multi-ink printing device or a multi-coating printing device having a plurality of printing machines arranged in sequence and a drying device between adjacent printing stocks, and the drying device has the above-described structure. That's good. Such a multi-ink printing or multi-coating printing device has a common single intermittent-acting gripping system between the printing press and the drying station 1' of said printing device.

Advantages The advantages obtained by the drying device of the present invention are that the wet coating of the abrasive sheet can be exposed to the drying device for a period of time, which is located in close proximity to the drying or curing means. The amount of energy and power required is greatly reduced! I can do that, j
- The hardness can be selected to be so low that the coating is skin cured, in which case it is not necessary to cure or cure the entire coating in the post-treatment of the material.

Another advantage of this invention is that it is possible to produce multi-ink or multi-coating stamps by using a series of printing machines connected in a line one after the other and a drying device arranged between adjacent printing stations. This means that the overall length of the complete device consisting of a printing machine can be significantly shortened.

The main features of the drying device for drying the printed materials of the invention of the second invention are described in claim (1), and the main features of the drying device for drying the printed materials of the invention are as follows: The main features of the I-ding printing device are as set forth in claim (1).
) section (described).

In the following, embodiments of the present invention will be described with reference to the drawings.

Explanation of ll bow, Shii implementation 1 shi 1 Figure 1 shows a printing machine (1) arranged in order of order.

FIG. 2 is a side view of a multi-ink printing or multi-coating printing device having (2), (3) and intermediate drying devices (4), (5).

There is a material feeding section (1) upstream of the printing machine (1), and as shown in FIG.
off rneans) (8).
) are placed.

The printing machines (1), (2), (3) may be known silk screen printing machines, the mode of operation of which will not be described here for the sake of brevity.

The fact that the illustrated embodiment consists of three printing machines and two intermediate dryers is not meant to imply that the invention is limited to that number. is equal to the number of coatings applied to the material.

Since the drying devices (4) and (5) are identical to each other,
Only the mounting W(4) will be explained.

The device (4) is therefore configured to dry the printed material, said material being printed on the silk screen 111184.
< 1) Drying device (4) with attached sawtooth stamp
is a conveying path for feeding the material through the drying device (4);
That is, the material is fed in at one end (4a) and the material is fed in at the other end (4a).
4b) It is interesting to know what to do with the conveyance path.

The drying device (4) has a means (9) for drying or curing the coating (ink or base) of 1 family 1. Only two such means are indicated for this purpose. Easily understood J, Uni, actually all 11 of the month 11 stamped i! A plurality of these various means are arranged to overturn, but such a single stage arrangement is simplified,
The details of the method for distributing this means (9) will not be explained because it can be shifted as appropriate.

1-\Printing machines (2), (3) and drying equipment! (4
).

(5) are connected to each other to form a doublet, for which an interconnected gripping system consisting of a plurality of gripping devices, i.e. gripping bars, each of which ) is configured to grasp and hold firmly. The gripping system is indicated in the drawing by the reference symbol (lO). Material with 4=Fj stamp (11)
is held firmly by a gripping bar <10a).

The impression or coating is applied by the printing machine via the stencil, the stencil being incorporated into the printing machine and taken up in the frame (12), the printing machine furthermore being already known. Squeegee and filling means (13
). During the printing sequence, the gripping system is fixed and the gripping bar is locked and fixed.

Once the imprinting sequence of the imprint is completed, the gripping system is displaced forward and the gripping bar (10a') and the material (11') which has been gripped by it are exposed to the coating drying or coating curing means (9). located close to. IJi before displacement of the gripping system occurs
A sheet of long material H is fed from a gripping device located behind said gripping bar (10'), placed under a frame (12) and fed to a similar printing machine. Stamping machine (
During the time spent in printing the next sheet in 1), the means (9) serve to dry and dry the wet coating of the sheet of material (11').

The print drying or curing means (9) is then configured to operate intermittently, this operation being shown in FIG.
J (12), which controls the wet coating of the sheet of material or the time, drying and nearing means (9) which are placed in close proximity to said means. ; Tl& has been made so that it will be the first in line.

In this embodiment, the drying or curing means (9) consist of one or more lamps producing a violet line;
It is preferred that the lamp comprises a mercury lamp "OK2°" of the type commercially available at 1 ps).

7. The silver lamp used in accordance with this invention is chalk.
The choke is designated in FIG. 4 by the reference numeral (13) and the igniter by the reference numeral (14). 71st Silver Rump “l-I OK 2°” commercially available from Philips (when used frequently,
. Christe Co., Ltd. (Jvlay G, Chrisje
It is known that it is suitable to use the choke "Q I V2O0O-04,21 (" (13)) manufactured by
4) is a Swiss restaurant named ``Kuen Helgel (Leuen)''.
There may also be an igniter ZGes commercially available from Berger.

For the use of the control means (12) and the mercury lamp mentioned above by way of example, the control means is energized and the zunawa excitation circuit (
15) and controlling said control means by means of a circuit (15) to obtain a working state in which the lamp is energized with at least one intermittent working time, the ignition time is sufficiently long, and the ignition pulses are intermittently active. It is desirable to be able to do so, and this is preferred because it provides a more complete effect.

The ignition pulse is co-supplied by the conductor (lsa).

As will be appreciated, the operating conditions of the lamp are met by normal operation with a sufficiently high frequency and a sufficiently long excitation time to ignite the lamp by the voltage supplied across the lamp by the control circuit.

Lamp iZl: A slightly higher ignition voltage is required than normal action across the lamp (9) during ignition, since it may cool down slightly between successive energization times.

The control means are arranged such that the lamp (9) is energized for a period of time such that the rate of energy given up by the lamp slightly exceeds the minimum of the material per unit of area. It's okay. This can be achieved by a sensor (17), a sensor (17)
is placed below the lamp (9), and the 21 inductor (18
) is connected to the control circuit <12).

-・-F's first shift like this is approximately 0.18W/cn? This is known to be sufficient for skin curing of -1-ting.

It is particularly convenient if the control means are controlled primarily by the printing machine (1) and the excitation bus is generated via the conductor (1G) for igniting the lamp (9).

For example, in the olden days when the monthly charge reached the correct printing position on the printing press, the printing press would send a trigger pulse and the coating on the sheet of one material would cure in the dryer while the coating on the sheet of other material would be cured at the same time. The sheet may also be imprinted.

The drying device (4) is provided with a tape JL (20) that supports the material (11°). Although not shown, the table (20) has a secondary pressure source (21
) and a source of pressurized air (22) are formed, the coating is dried and cured by a lamp (9), the table is not shown. Therefore, a part of the heat emitted by the lamp (9) is directly absorbed by those parts of the table located outside the area covered by the material and is absorbed by the fourth material or the table (20 ) (!: As a result of direct contact, the heat radiated to the monthly charge (11'> is also transferred to the table. The rest of the time,
The table is connected to a pressure horn air source (22). As a result, the gripping bar (10a') moves the material to the next printing machine (2).
When the material is moved, the material (pressure) is supported by an air cushion and can easily come out of the table, and the air flow cools the heated tape (old 20) and the next printed 441[ Sea 1- or printing machine (1) to drying device (
11), the table is relatively cooled.

1441: It is particularly suitable to choose the number of lamps (9) radiated from the lamp (9) per unit of time so that the radiation is skin cured.

= 1-Ting skin curing (J is necessary because: the coating then becomes hard enough that no special coating is required first =
This is because 1-ting can be given as 1:1.

Completely code the code so that it is understood.

If arylene is desired, the emission Q from the lamp,
The intensity of one line can be increased and the time the lamp is energized can be increased.

This invention provides a plurality of printing machines (1) connected to each other.

Multi-ink printing or ma+1 with (2), (3)
Regarding the di-coating printing apparatus, the printing machines are sequentially arranged one after the other. Drying devices (4) and (5) are arranged between the printing stocks adjacent to each other. The apparatus has a gripping system 1, common to the entire printing apparatus, which gripping system is used for all printing machines (1), (2) and (3) and dryers Ff (4), (5). ).

The aforementioned gripping system operates intermittently, the material being displaced from the material laying-on means (6) to the gripping device, which grips the material and transfers it to the printing machine ([). 111 and then the material is moved to position 111 by the gripping system j1 and the drying device? 1 (4), and this is repeated. In the printing machine (3), when the final coating is applied to the material, the 44th unit applies the drying device (7) to the JIT! After the coating of material is completely dried and cured, said material 1F is sent from the drying device (7) to the support means (8) 2).

Part (25a) of the drying device 2' (25)
is inserted toward grip'<-(LOa), and part (2
5 is inserted towards the gripping bar (10a') so that the gripping device of one printing machine and the gripping device of the adjacent drying device form a reservoir sealing means for sealing the inlet and outlet openings of the drying device; The light and heat radiated from the drying device (4) to the printing presses (1) and (2) by the 5. It is particularly preferable to prevent the inconvenience caused by rain.

The present invention is not limited to the embodiments described above, but can be modified within the scope of the claims.

Although details of the control means are not described, it is believed that such a control means can be easily understood by a person of ordinary skill. A suitable excitation time is 0.
5 to 2.0 seconds, and 0.8 to 1.2 seconds.
