9 is a plan view showing the embroidery frame driving unit of the embroidery machine according to the present invention, as shown in the embroidery frame 103 is arranged one by one for each head group.

Guide rails 93 are formed on the right side of the embroidery frame 103 in the X-axis direction, and an X-axis driving linear motor 91 is mounted along the guide rails 93, and the X-axis driving is performed. The fixing bracket 95 is fixed to one side of the linear motor 91 for the yoke, and the Y-axis frame of the embroidery frame 103 is slidably coupled to the inner surface of the fixing bracket 95.

In addition, a guide rail 99 is formed in the Y-axis direction at the rear of each embroidery frame 103, and a Y-axis linear motor 97 is mounted along the guide rail 99. The fixing bracket 97 is fixed to one side of the linear motor 97, and the Y-axis frame of the embroidery frame 103 is slidably coupled to the inner surface of the fixing bracket 97.

Referring to the operation and effects of the self-driven multi-head embroidery machine according to the present invention configured as described above are as follows.

When power is applied to the embroidery machine, the linear motor 73 for vertical driving of the head is driven through the main controller 11. The vertical driving linear motor 73 is driven up and down in accordance with the data input by the embroidery program of the embroidery machine.

The vertical drive linear motor 73 driven up and down moves the slider 43 in the same direction along the needle shaft 45, and the slider 43 moved in the up and down direction moves the needle controller 47. Move in the same direction. The up and down needle bar control body 47 moves the fixed bracket 49 coupled with the needle bar control body 47 in the same direction, and the fixed bracket 49 finally moves up and down with the needle bar 27. .

At this time, when the forward and reverse motor 75 is driven by the controller 11, the forward and reverse motor 75 rotates the thread take-up driving lever 37 up and down, and the thread take-up driving lever 37 is a thread take-up. The engagement of the drive gear 39 causes the thread take-up 40 to swing up and down to proceed.

As described above, the controller can be driven by individually controlling the needle bar of each head by the controller so that the work can be adjusted according to the convenience of the operator.

Subsequently, when the needle bar 27 is driven by the controller 11 and a signal is transmitted to the small motor 81 of the kiln, the small motor 81 mounted on the rotary shaft 20a of the kiln is driven to Embroidery is performed by rotating the kiln in accordance with the vertical movement of the needle bar 27.

In addition, at the discretion of the operator, embroidery work can be performed independently for each head group, and in this case, embroidery is performed by the embroidery frame 103 arranged for each head group as shown in FIG. 9. At this time, the embroidery frame 103 is driven by the operation of the X-axis linear motor 91 and the Y-axis linear motor 97 in response to the signal of the controller (11). The operated X-axis driving linear motor 91 slides the embroidery frame 103 in the X-axis direction through the fixing bracket 95, and the operated Y-axis driving linear motor 97 is fixed bracket ( The embroidery frame 103 is moved in the Y-axis direction through 101 to execute programmed embroidery.

On the other hand, the controller 11 operates the stationary motor 75 and the vertical driving linear motor 73 installed on the head 5, and at the same time a plurality of embroidery frame 103 installed on the work table (3) Are moved in the X and Y-axis directions, respectively, and the operation sequence is as follows.

First, in the case of placing only one number to be produced in the embroidery frame 103, the controller 11 is the X-axis driving linear motor 91 and Y-axis installed in the one embroidery frame 103 Commands are transmitted only to the driving linear motor 97 to move on the work table 3 in the X and Y axis directions.

Unlike the above, in the case of producing two patterns or a medium quantity, the controller 11 is adjusted to transmit a command to each of the linear motors for driving X and Y axes installed in the one or two embroidery frames. . Accordingly, the X and Y axis driving linear motors operate to move the one or two embroidery frames in the X and Y axis directions, respectively. At this time, the embroidery frame may be embroidered by setting one or two patterns.

Another method is to move the three embroidery frames in the X, Y axis direction at the same time on the work table for mass production, by adjusting the controller 11 to the X, Y axis installed in the three index frame Allow the driving linear motors to operate individually. In this case, the three embroidery frames may be embroidered by setting one pattern or two or more patterns, respectively.

When three colors are embroidered on the fabric in the process of operating the three embroidery frames as described above, the controller 11 transmits a command to the color change, when the head 5 is pushed or pulled, The thread take-up 40 is slidably moved to a predetermined position in the transverse direction. Therefore, the thread take-up 40 is operated while the gears of the new thread take-up 40 to supply the thread of the corresponding color gears.

In addition to the three embroidery frames installed as described above, if you want to produce a variety of patterns and more quantities, more embroidery frames can be installed for each head group.

The present invention is not limited to the embodiments described above, and various modifications and changes can be made by those skilled in the art, which are included in the spirit and scope of the present invention as defined in the appended claims.

As described above, the self-driven multi-head embroidery machine according to the present invention is equipped with a linear motor inside the head to directly drive the needle bar, and directly drives the kiln through the small motor, thereby simplifying the structure and making the work process easier. . In particular, by eliminating the spindle motor that has been the cause of the noise and the structure associated with it, it is possible to realize the simplification of the structure, low noise, low vibration, and improve the durability of the embroidery machine. In addition, when a small amount of multiple embroidery work can be driven separately for each head group, it is possible to implement a variety of embroidery work at the same time with a single embroidery machine to maximize the effect of the work.
