Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a droplet jetting automatic pattern recording device, and more particularly to a droplet jetting automatic pattern recording device suitable for creating patterns on fabric in a short time with almost no human intervention. In the traditional dyeing industry, all designs on fabrics are created by hand using paintbrushes and dyes, which takes a very long time, increases labor costs, and is expensive. It had become a thing. Furthermore, even when the same design is used repeatedly, it is difficult to ensure that it is exactly the same because it relies on handwriting.

Furthermore, the pattern creation process takes a long time and must be done in the same working position, which is physically tiring and unfavorable in terms of occupational health.

The present invention has been made in view of the above, and its purpose is to provide a droplet jet automatic pattern recording device that can create patterns on fabric in a short time without any manual intervention. It is in.

A feature of the present invention is that needle-like bins are provided on the outer periphery for feeding the fabric in the longitudinal direction. A fabric feeding system comprising: a fabric feeding drum that presses a pressure roller provided with a fabric and rotationally holds a fabric on the fabric; and a winding sitram that winds up the fabric fed through the feeding drum. Appropriate tension is applied by the feeding means, and a pattern is recorded on the fabric on the feeding citram by a recording head of at least one color of the droplet jet recording means, and the recording head is controlled by the feeding mechanism by a recording head drive mechanism. The recording head drive mechanism and the above-mentioned feed ram record various symbol patterns based on an operation similar to that of an XY plotter, and use a computer according to symbol information from a pattern storage section. The present invention has a structure in which a pattern is recorded on the cloth by a linked recording control section.

The present invention will be described below with reference to FIG. This will be explained in detail using the embodiment shown in FIG.

FIG. 1 is a functional lock diagram showing an embodiment of the device of the present invention. In FIG. 1, reference numeral 1 denotes a droplet jet recording head, and one or more recording heads are provided depending on the purpose of monochrome or multicolor recording. Reference numeral 2 denotes a recording head drive motor for driving the recording head 1. Note that depending on the required recording speed, the recording head 1
The recording head 1 only needs to be capable of ejecting single or multi-colored droplets, although the operational principle and scale of the recording head 1 are different.

Droplet jet recording methods are broadly divided into two types based on the recording principle: a recording method that uses droplet charge modulation, and an on-demand recording method that ejects droplet ink only by pressure. # As development continues, it has become a well-known technology in the field of computer recording terminals as a non-impact high-speed character recording technology for can markings and printers, so I will not explain it here, but any recording It may also be a method. Generally, the recording method using droplet charge modulation is relatively fast (several K at the droplet ejection frequency).
Hz to several hundred KHz), and the on-demand recording method is relatively slow (droplet ejection frequency of several KHz).
z to several KHz).

3 is a recording control unit using a computer; 4 is a cloth 6'i made of woven chemical fibers or animal fibers with needle-like bins 5 on the outer periphery; 7 is a feed citram drive motor that rotationally drives the feed citram 4; 8 is a feeding citram drive motor that rotates the feeding citram 4; and 8 is a needle-shaped bottle 5 that is engaged with the outer periphery of the feeding drum 4, which is arranged so as to press the fabric 6 between the thresholds. 10 is a press roller provided with a concave groove 9 for feeding out the fabric 6;
Reference numeral 11 denotes a feed-out drum drive motor that rotationally drives the fabric feed-out drum IO, 12 a take-up drum for winding up the fabric 6 sent out from the feed sheet ram 4, and 13 a winder for rotationally driving the wind-up sheet ram 12. The taking drum drive motor includes a feed drum drive motor 7, a feed drum drive motor 1, and a feed drum drive motor 3, which are controlled by a recording control unit 3 so that a constant tension is always applied to the fabric 6. The fabric 6 is always fed around the circumference to the feed drum 4 with a constant tension even when the feed drum 4 rotates arbitrarily in the forward and reverse directions.

d is a symbol pattern generating section, which normally records the symbol pattern to be recorded on a recording element such as a 70-tube disc, magnetic disk, or magnetic tape in advance, and controls the recording of the same symbol pattern repeatedly from this recording section. Part 3
The recording control unit 3 controls the movement t1 of the recording head l in the axial direction (X-axis direction) of the excess drum 4 according to the symbol pattern, and also controls the rotational direction (
A desired pattern and color are repeatedly recorded on the fabric 6 by controlling the rotation speed (travel speed of the fabric 6). These recording operations are generally similar to those performed by an XY plotter.

In addition, in the above-described apparatus of the present invention, the feed drum 4
The needle-like bottle 5 with a needle-like tip is planted on the outer periphery of the fabric 6 because it is not possible to make a feed hole in the fabric 6 in order to feed the fabric 6. This is for the purpose of Further, the reason why the pressure roller 8 is provided with the groove 9 in which the needle pin 5 engages is to ensure the feeding of the fabric 6 and to prevent the tip of the needle pin 5 from being damaged.

The pressure roller 8 is pressed against the outer periphery of the feed ram 4 using a spring or the like, and is configured to rotate freely as the feed ram 4 rotates. Further, as the needle bottle 5, one of the size of a normal sewing needle is used. The width of cloth 6 is 70cm and 90cm.
e There are various types such as 140 cvt, and the paper width is wider than that of Glock paper, and it is also soft and easily warped, so the needle bottle 5 can be placed not only at both ends of the feed citram 4 but also in the middle. be.

FIG. 2 is a structural diagram showing an embodiment of the feed ram 4 and the pressure roller 8 shown in FIG. 1, in which (a) is a front view and (b) is a side view. In FIG. 2, numeral 4 is a feeding citrum, and 5 is a needle-shaped bottle planted on the outer periphery of the feeding citrum 4, which is planted at both ends and the middle part. Reference numeral 8 denotes pressure rollers, and in the figure, three pressure rollers are arranged corresponding to the needle bottles 5, and the needle bottles 5 engage with the outer periphery of the portion of each pressure roller 8 that corresponds to the needle bottles 5. #I#9 is provided, each pressure roller 8
are connected by a shaft 15, and the shaft 15 is pulled in the direction of the feed drum 4 by a spring 16 (2#) to press the pressure roller 8 against the outer periphery of the feed drum 4.

In this way, by arranging a plurality of needle-shaped beads 15 in a plurality of rows in the middle part of the cloth 6 according to the width of the cloth, distortion of the pattern can be avoided.

According to the above-mentioned example of the performance of the present invention, (1) A pattern similar to the conventional pattern can be created on the cloth 6 at a speed several tens to hundreds of times faster than the conventional manual pattern creation.

(2) Since work can be done in a short time, it is possible to significantly reduce labor costs.

(3) Since the work can be done with almost no human intervention, there are great advantages in terms of bone health.

(4) Rounding that can be automatically drawn When creating the same design over and over again, only manual setup work is required, and then completely automatic design creation is possible, resulting in a significant reduction in labor.

(5) Since the needle-shaped bottle 5 is planted on the outer peripheral surface of the feeding citram 4, the fabric 6 can be fed out reliably, and
By planting a plurality of rows of needle-like bottles 5, distortion of the pattern was avoided and a good pattern could be created.

As explained above, according to the present invention, there is an effect that a pattern can be created on cloth in a short time without much manual intervention.
