Next, the operation of the apparatus having the above-described structure will be described step by step.

(Fabric Supply Process) First, the gluing device (9)
As a result, an adhesive called an adhesive for sticking the cloth (F) to be printed is uniformly applied to the upper surface of the conveyor belt (3). On the other hand, according to the supply device (30), the tension of the cloth (F) unwound from the unwinding device (31) is kept constant by the dancer bar (32), and the guide roller (3).
3), the synchronization mechanism (34), (3
It is fed onto the conveyor belt (3) via 5). Then, the cloth (F) is pasted between the sticking roller (36) and the cloth (F) is stuck on the conveyor belt (3) in a close contact state. At that time, it is necessary to attach the fabric (F) without excessively stretching it and without causing wrinkles.

At this time, the conveyor belt (3) is driven intermittently, whereas the cloth (F) is unwound at a constant speed. Therefore, when the conveyor belt (3) is stopped, the sticking roller (36).
The fabric (F) is in a state of being excessively supplied in front of, causing slack. Therefore, the synchronization mechanisms (34) and (35) are moved in the directions of arrows BC to absorb the difference in moving speed (that is, slack) of the cloth (F). Specifically, the conveyor belt (3)
While the is stopped, the synchronization mechanisms (34) and (35) are moved in the direction of arrow B (the synchronization mechanisms (34) and (35) and the sticking roller (36) are connected, Mechanism (3
When 4) and (35) move in the direction of arrow B, the sticking roller (36 also moves in the direction of arrow B), and the cloth (F) sent is stored for a certain length. On the contrary, while the conveyor belt (3) is driven, the synchronization mechanisms (34) and (35) are indicated by the arrow C.
The fabric (F) stored is discharged at a stretch. The technique of supplying the cloth (F) continuously conveyed at a constant speed onto the conveyor belt (3) which is intermittently driven is already disclosed in Japanese Examined Patent Publication No. 64-7585.

Further, the conveyance pitch of the conveyor belt (3) which is intermittently fed is set to the ink jet head (2).
It is the same as the printing width (width in the longitudinal direction of the fabric) of 3). The printing width of the plate printing section (10) is an integral multiple of the printing width of the inkjet head (23).

(Plate-printing step) In the plate-printing section (10), the conveyor belt (3) conveys the fabric (F) for several pitches (corresponding to the printing width in plate-printing), and then the following operation is performed. It That is, first, the up-and-down drive means (3) is driven to move the screen plate mold (11) downward to bring the screen plate mold (11) into close contact with the cloth (F). Then, of the two cages (15) that have been moved to one end in advance on the screen plate mold (11), the one on the rear side in the traveling direction descends and comes into close contact with the screen plate mold (11), and the cloth width direction 1 direction (for example, the H direction shown by the arrow in FIG. 2),
The printing paste (14) previously supplied on the screen plate mold (11) is scratched. The screen plate mold (11) is perforated with a pattern of fine holes, and the printing paste (14) that has passed through the fine holes reaches the cloth (F) and the desired pattern is printed on the cloth (F). .

After the cage (15) reaches the end of the moving direction, the up-and-down driving means (3) is driven to move the screen plate mold (11) upward to move the screen plate mold (11).
Is peeled from the fabric (F). Then, when a gap is created between the screen plate mold (11) and the cloth (F), the conveyor belt (3) is driven to move the cloth (F) to the next printing position (the position below the next screen plate mold). Convey only the width of the printing plate. Then, the above operation is repeated to sequentially print the fabric (F). At that time, with respect to the operation of the cage (15) after reaching the edge in the cloth width direction, the two cages (15) are both moved upward. There is also a method to move it back to the specified position by moving it to the
It is also possible to enhance the productivity of printing by scraping the printing paste (14) with a cage reverse to that of the outward route of 5).

As described above, by printing using a plurality of screen plate molds, it is possible to print a pattern of a desired color pattern on the fabric (F). In this plate printing process, a large pattern with a small number of colors is printed.

(Plateless Printing Step) In the plateless printing section (20), one cycle (1
The following operation is performed during the conveyance of the pitch). That is, first, a drive motor and a ball screw (both not shown) are driven while the fabric (F) is stopped to move the saddle (26) along the slide (25) (this is called scanning). This causes the inkjet head (23) to move in the width direction of the cloth (F). During the movement, the inkjet head (23) sequentially receives a drive signal from a control device (not shown) and supplies the ink supplied from the ink storage tank (21) via the pipe (22) to the cloth ( Spray on F) and print the desired pattern. The inkjet head (23) is provided with a plurality of nozzles in the longitudinal direction of the fabric (F), and can perform line-shaped printing of a predetermined width by one scanning.

There is also a method of returning to the original position without jetting after reaching the other end in the cloth width direction, but if the control device has a function of converting the pattern pattern into mirror symmetry, the ink jet head ( It is also possible to increase the printing productivity by performing the injection control even in the return path of 23).
In this manner, the desired pattern can be printed by sequentially scanning the inkjet head (23) in the width direction of the fabric (F).

Further, multicolor printing is possible by preparing a plurality of dye / ink colors. Usually, three colors of yellow (Y), magenta (M), and cyan (C) are often used. Further, black (K) may be added.
In this embodiment, the inkjet head (23), the ink storage tank (21) and the pipe (22) are set to yellow (Y),
There are four sets corresponding to each color of magenta (M), cyan (C), and black (K). According to the printing with the inkjet head (23), the trajectory of each jet has a halftone dot structure on the cloth (F), and it is possible to express fine lines and patterns as well as almost all colors. . Therefore, in this plateless printing process, printing of a fine pattern having a large number of colors is performed. There are various existing ink jet methods for ejecting these dyes and inks in the form of fine droplets, which can be adopted.

(Discharging Step) In this step, first, the cloth (F) stuck on the conveyor belt (3) is peeled upward by the peeling device (41) of the discharging device (40). Then,
Before the peeled cloth (F) is folded, in order to prevent color transfer, the water contained in the dye printed by the drying device (42) is removed. Then, again, the swinging device (43) is swung in the direction of the arrow D-E to swing the swinging device (43) on the carriage (44).

The printing paste is scratched with a cage,
Since a part of the material passes through the cloth (F) and is stored between the cloth (F) and the conveyor belt (3), when the cloth is peeled off,
Printing paste is left on the conveyor belt (3). Since the conveyor belt (3) circulates, it is necessary to wash the remaining printing paste (14) by the washing device (8) in preparation for the upholstery of the next cloth (F). Specifically, the printing paste is washed with a brush / sponge while applying warm water. After that, the adhesive, which is a new clean adhesive, is uniformly applied onto the conveyor belt (3) by the gluing device (9).

Next, a method for matching a design by plate printing and a design by plateless printing will be described.

Plate-printing section (10) and non-plate-printing section (20)
Since and have different mechanisms, it is necessary to precisely match the pattern by the plate printing and the pattern by the non-plate printing in order to obtain a precise printing pattern. For that purpose, first, a mark (51) (FIG. 5) of an isosceles right triangle for alignment is provided on the conveyor belt (3). On the other hand, a transparent mark of congruent isosceles right triangle is also provided on the screen plate mold. Then, the screen plate mold is set so that the mark (51) of the conveyor belt (3) matches the mark of the screen plate mold. The screen plate type mark and the pattern are set in a fixed positional relationship.

In the plateless printing section (20), the mark (51) on the conveyor belt (3) which has reached the reading position of the position confirmation sensor (50) is marked by the position confirmation sensor (50).
Read by. In this example, as shown in FIGS. 4 and 5, three spot type sensors are provided so as to correspond to the respective vertex positions of the mark (51). Then, the control device (not shown) inputs the detection signals of the three position confirmation sensors (50) and processes them in the processing section. From the result, all the position confirmation sensors (50) mark ( 51), the adjusting mechanism driving unit drives the adjusting mechanism (27) to adjust the position of the inkjet head (23) in the longitudinal direction, and the width direction adjusting unit operates the reciprocating mechanism (24). The amount of deviation of the inkjet head (23) in the width direction of the cloth (F) is calculated by driving. Then, the width-direction adjusting unit, based on the calculated displacement amount, the reciprocating mechanism (24) and the inkjet head (2).
Correct the drive in 3). The control device (not shown)
The data stored in the storage means also takes into consideration the positional relationship between the mark and the pattern, as in the case of the screen plate type described above.

As described above, with the mark (51) provided on the conveyor belt (3) as a reference, the printing pattern by the screen plate mold and the printing pattern by the ink jet head (23) can be matched. The position confirmation sensor (5
For 0), a CCD camera or the like can be used in addition to the spot type sensor. According to this, the imaged two-dimensional image data is subjected to image processing to recognize the position of the mark (51).

In this way, by a series of operations, that is, with the cloth (F) adhered to the conveyor belt (3), the plate printing and the plateless printing are sequentially performed without peeling off. This makes it possible to easily match the patterns in both textile printing.

Further, the order of the plate printing and the plateless printing is not particularly limited, but if the plateless printing is followed by the plateless printing, it is possible to print finely on the plate printing part which has been printed over a wide area. It is possible to form a non-printing printing portion, and it is possible to form a more complicated fine pattern.

In the ink jet, the color of the dye to be jetted is
It can be easily changed by computer processing.
The same applies to the handle. Further, the color / pattern can be easily changed for each injection by pre-registering the color / pattern or by regularly programming the change pattern.

As described in detail above, according to the apparatus of the embodiment, the following three points, which cannot be realized by the conventional printing, can be realized. That is, the first is that it is possible to easily realize a printing including a very fine dot-like pattern that cannot be expressed by a conventional printing method such as screen printing or roller printing. Further, the dot density can be changed arbitrarily, and various neutral colors such as a blur pattern can be expressed.

The second is that it is possible to print immediately in response to a request from the user. In addition, it is possible to make minor changes to the pattern according to the user's request.

In the third method, the same pattern can always be produced for the basic pattern, but the pattern pattern of the ink jet printing section can be changed immediately. Specifically, by partially printing a pattern the user likes, such as initials and one-point marks, and by combining them, it is possible to industrially manufacture the only pattern in the world. .

Although the embodiments of the present invention have been described above, it goes without saying that the specific embodiments of the present invention are not limited to these. In particular, in the above example, a flat screen printing machine was used as the plate printing means, but a roller printing machine or a rotary screen printing machine can also be used.

Further, in the above-described example, a position adjusting mark is provided on the conveyor belt (3), and the positions of the screen plate mold (11) and the ink jet head (23) are adjusted in accordance with the position adjusting mark. However, the screen plate mold (11) is provided with a position adjustment mark printing part in addition to the pattern printing part, and the position adjustment mark (51) is printed on the cloth (F) or the conveyor belt (3) together with the pattern, Then, similarly to the above-mentioned example, the position confirmation sensor (50) may detect the position adjustment mark (51), and the adjustment mechanism (27) may adjust the position of the inkjet head based on the detection data.

The ink jet head (23)
The length in the longitudinal direction of the cloth (F) of the screen plate mold (1
When the printing width of 1) is matched, the most time-efficient printing can be performed, but in reality it is difficult to manufacture such a large inkjet head (23), so 1 to the inkjet head (23)
It is preferable to consider from the viewpoint of design so that the plateless printing is completed only by scanning twice.

According to the invention of 4 and 4, the large pattern portion having a small number of colors is printed by the plate printing means, and the small pattern portion having a large number of colors is printed by the plateless printing means, so that only the plateless printing means prints. Productivity is significantly improved compared to the case. Further, when the plate printing is set to a large pattern, the printing plate can be produced in a smaller number of days. Furthermore, by using a large pattern printing plate in common and changing only the pattern of the small pattern non-printing part to print many types of color patterns, productivity will be further improved and customer's demand for short delivery time will be met. Can fully respond.

Further, according to the inventions of claims 2, 3, 5, 6 and 7, it is possible to carry out the printing because the positional relationship between the plate-less printing pattern and the non-printing printing pattern can always be kept normal. It is possible to prevent the design from shifting.
