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

(Fabric supply step) First, a gluing device (9)
Thereby, an adhesive called a laying agent for adhering the cloth (F) to be printed is uniformly applied to the upper surface of the transport belt (3). On the other hand, according to the supply device (30), the tension of the cloth (F) unwound from the feeding device (31) is kept constant by the dancer bar (32), and the guide roller (3).
Synchronization mechanisms (34), (3) without meandering due to 3)
Via 5), it is fed onto a conveyor belt (3). Then, the cloth (F) passes through the space between the adhering roller (36) and is adhered in a state in which the cloth (F) is in close contact with the transport belt (3). At this time, the fabric (F) needs to be adhered without excessive tension and without wrinkles.

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

The conveyance pitch of the conveyance belt (3) which is intermittently fed is the same as that of the ink jet head (2).
The printing width (width in the longitudinal direction of the fabric) is the same as 3). The printing width in the plate printing portion (10) is an integral multiple of the printing width of the inkjet head (23).

(Printing step for printing) In the printing section (10), the following operation is performed after the transport belt (3) transports the fabric (F) for several pitches (the printing width in plate printing). You. That is, first, the vertical drive means (3) is driven to move the screen plate mold (11) downward, and the screen plate mold (11) is brought into close contact with the cloth (F). Then, of the two cages (15) previously brought to one end on the screen stencil (11), the one on the rear side in the traveling direction descends, closely adheres to the screen stencil (11), and is moved in the fabric width direction. In one direction (for example, the direction indicated by the arrow H in FIG. 2),
The printing paste (14) supplied in advance on the screen mold (11) is scraped. A pattern of micropores is perforated in the screen mold (11), and the printing paste (14) passing through the micropores reaches the fabric (F), and a desired pattern is printed on the fabric (F). .

After the cage (15) reaches the end in the moving direction, the vertical driving means (3) is driven to move the screen mold (11) upward, and the screen mold (11) is moved.
Is peeled from the fabric (F). Next, when a gap is formed between the screen stencil (11) and the fabric (F), the conveyor belt (3) is driven to move the fabric (F) to the next printing location (the position below the next screen stencil). It is transported by the width of the plate printing. Then, the above operation is repeated to sequentially print on the fabric (F). At this time, the operation of the scaffold (15) after reaching the end in the fabric width direction is performed with both of the two cages (15) facing upward. To return to a predetermined position, but for the return path, two cages (1
In 5), by scraping the printing paste (14) with the reverse of the outward path, it is possible to increase the printing productivity.

As described above, printing with a desired color and pattern can be performed on the cloth (F) by printing using a plurality of screen stencils. In this plate printing process, a large pattern with a small number of colors is printed.

(Print-less printing step) In the print-free printing section (20), during one cycle of the intermittent drive of the transport belt (3), (1)
The following operation is performed during (pitch transport). That is, first, the drive motor and the ball screw (both not shown) are driven while the cloth (F) is stopped, and the saddle (26) is moved along the slide (25) (this is called scanning). Thereby, the inkjet head (23) moves in the width direction of the cloth (F). During the movement, the ink jet head (23) sequentially receives a drive signal from a control device (not shown) and converts the ink supplied from the ink storage tank (21) via the pipe (22) into a fabric ( F) to print the desired pattern. The ink jet head (23) is provided with a plurality of nozzles in the longitudinal direction of the cloth (F), and can perform line printing with a predetermined width by one scan.

After reaching the other end in the fabric width direction, there is also a method of returning to the original position without jetting. However, if the control device has a function of converting the design pattern into mirror-symmetrical processing, the ink jet head ( It is also possible to increase the productivity of printing by performing ejection control in the return path of 23).
In this manner, a desired pattern can be printed by sequentially scanning the ink jet head (23) in the width direction of the cloth (F).

By preparing a plurality of dye / ink colors, multicolor printing can be performed. Usually, three colors of yellow (Y), magenta (M), and cyan (C) are often used. Further, black (K) may be added.
In this embodiment, the ink jet head (23), the ink storage tank (21) and the pipe (22) are yellow (Y),
There are four sets corresponding to each color of magenta (M), cyan (C), and black (K). According to the printing by the ink jet head (23), the trajectory of each jet has a dot structure on the cloth (F) by dots, so that fine lines and patterns can be expressed, and almost all colors can be expressed. . Therefore, in this plateless printing process, printing of a fine pattern with many colors is performed. There are various types of existing technologies for an ink jet system for jetting the dyes and inks into fine droplets, and these can be adopted.

(Discharge step) In this step, first, the cloth (F) stuck on the transport belt (3) is peeled upward by the peeling device (41) of the discharge device (40). Then
Before folding the peeled fabric (F), moisture contained in the printed dye is removed by a drying device (42) in order to prevent color transfer. Then, the swinging device (43) is swung in the direction indicated by the arrow D-E, and is swung over the carriage (44).

Also, after the printing paste is scratched with a
Since a part of the cloth is transmitted through the cloth (F) and stored between the cloth (F) and the conveyor belt (3), when the cloth is peeled,
The printing paste is left on the conveyor belt (3). Since the conveyor belt (3) orbits, it is necessary to wash the remaining printing paste (14) in preparation for the next fabric (F) grounding by the washing device (8). Specifically, the printed paste is washed with a brush and sponge while applying warm water. Thereafter, an adhesive, which is a new clean upholstery, is uniformly applied onto the conveyor belt (3) by the gluing device (9).

Next, a description will be given of a method for matching a design by plate printing with a design by non-plate printing.

Plate printing section (10) and plateless printing section (20)
In order to obtain a precise printed pattern, it is necessary to precisely match the pattern by plate printing and the pattern by non-plate printing. For this purpose, first, a right-angled isosceles triangle mark (51) (FIG. 5) for positioning is provided on the conveyor belt (3). On the other hand, the screen plate type is also provided with a congruent right-angled isosceles triangle transparent mark. Then, the screen mold is set so that the mark of the screen mold matches the mark (51) of the conveyor belt (3). It should be noted that the screen plate type mark and the design are set in a fixed positional relationship.

In the plateless printing section (20), the mark (51) of the conveyor belt (3) reaching 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 each vertex position of the mark (51). The control device (not shown) receives 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) are marked (). In order to detect 51), the adjusting mechanism driving section drives the adjusting mechanism (27) to adjust the position of the ink jet head (23) in the longitudinal direction, and the width direction adjusting section controls the reciprocating mechanism (24). The inkjet head (23) is driven to calculate an amount of displacement of the fabric (F) in the width direction. Then, based on the calculated amount of displacement, the width direction adjusting section performs the reciprocating movement mechanism (24) and the inkjet head (2).
The driving of 3) is corrected. In addition, the control device (not shown)
The data stored in the storage means is also based on the positional relationship between the marks and the symbols, as in the case of the screen plate type described above.

As described above, it is possible to match the printed pattern by the screen printing mold with the printed pattern by the ink jet head (23) based on the mark (51) provided on the conveyor belt (3). In addition, 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 position of the mark (51) is recognized by performing image processing on the captured two-dimensional image data.

As described above, a series of plate printing and plateless printing are successively performed by a series of operations, that is, without leaving the fabric (F) adhered to the transport belt (3) and without peeling it once. This makes it possible to easily match the patterns in both printings.

The order of plate printing and plateless printing is not particularly limited. However, if plateless printing is performed after plate printing, fine printing is performed on the plate printing portion that has been widely printed. A non-printed portion can be formed, and a more complicated fine pattern can be formed.

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 pattern. Further, by registering the color / pattern in advance or programming the change pattern regularly, the color / pattern can be easily changed for each injection.

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, firstly, it is possible to easily realize printing including a very fine dot-shaped pattern which cannot be expressed by a conventional printing method such as screen printing or roller printing. Further, the dot density can be arbitrarily changed, and various intermediate colors such as a blur pattern can be expressed.

Second, it is possible to perform printing immediately in response to a request from a user. Furthermore, minor changes in the pattern at the request of the user are also possible.

Third, although the same pattern can always be produced with respect to the basic pattern, the pattern of the ink-jet printed portion can be changed immediately. More specifically, it is possible to industrially produce only the world's only pattern by partially printing the user's favorite pattern, for example, initials, one-point marks, etc., and by combining them. .

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 embodiments. In particular, in the above example, a flat screen printing machine was used as the plate printing means in the above example, 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 printing die (11) and the ink jet head (23) are adjusted in accordance with the position adjusting mark. However, the screen printing die (11) is provided with a position adjusting mark printing section in addition to the pattern printing section, and the position adjusting mark (51) is printed together with the pattern on the cloth (F) or the conveyor belt (3). Next, similarly to the above-described example, the position adjustment mark (51) may be detected by the position confirmation sensor (50), and the position of the inkjet head may be adjusted by the adjustment mechanism (27) based on the detection data.

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

[0051]

As described in detail above, claim 1 of the present invention
According to the inventions of (4) and (4), a large pattern portion having a small number of colors is printed by plate printing means, and a small pattern portion having a large number of colors is printed by a plateless printing means, thereby printing only by a plateless printing means. The productivity is significantly improved as compared with the case. In addition, if the plate printing is set to a large pattern, a printing plate can be manufactured in fewer days. Furthermore, if a large-sized printing plate is used in common, and only the pattern of the small-sized non-printed printing part is changed to print various types of color patterns, productivity can be further improved and customers can meet short-term delivery requirements. I can fully respond.

According to the second, third, fifth, sixth and seventh aspects of the present invention, the printing can be performed while always maintaining the positional relationship of the plateless printing pattern with respect to the plate printing pattern normally. It is possible to prevent the design from shifting.
