Create an embroidery pattern.

While the embroidery pattern is being created on the embroidery cloth 5 as described above, the determination process of step 2 determines that "N
If the determination is "O" and the embroidery pattern creation is interrupted or stopped, the process proceeds to step 4 to determine whether or not to perform applique embroidery. If the determination is "YES", the adhesive application control in step 5 is performed. The supply control of the applique and the sewing control of the applique in the step 7 are sequentially performed as described later.

That is, in the adhesive application control in step 5, the dispenser 15 is used to apply the adhesive to the application position of the applique determined in advance by the embroidery data, so that the frame is moved based on the embroidery data. By operating the mechanism 7, the embroidery cloth 5 is automatically moved in the X-axis direction and the Y-axis direction together with the embroidery frame 8, and a portion of the embroidery cloth 5 on which the applique is to be stuck is discharged to the discharge port 14 </ b> A of the dispenser 14.

Is lowered downward along the cylindrical portion 21A of the telescopic arm 21, and the applique sucked by the suction portion 22A is supplied so as to be pressed onto the adhesive application pattern.

As a result, the applique is automatically attached to the application position of the embroidery cloth 5 along the adhesive application pattern. After the applique is supplied, the vacuum pressure is released and the entire supply device 18 is returned to the standby position shown in FIG. In this case as well, data necessary for supplying the applique is stored in advance in the frame movement data in the embroidery data, and the frame movement mechanism 7 is operated based on this data, so that the embroidery cloth 5 Is moved to the lower side of the suction head 22 by the frame.

Next, in the applique sewing control in step 7, the frame moving mechanism 7 is operated based on the embroidery data in order to sew the applique stuck on the embroidery cloth 5 on the sewing head 4 side. Thereby, the embroidery cloth 5 is moved in the X-axis direction and the Y-axis direction together with the embroidery frame 8, and the applique stuck on the embroidery cloth 5 is opposed to the embroidery needle 6 of the sewing head 4 from above and below. In this state, the embroidery needle 6 is moved toward the embroidery cloth 5 by the sewing head 4 while moving the embroidery cloth 5 by the frame in the X-axis direction and the Y-axis direction.
By driving the embroidery cloth 5 downward, a stitch is formed on the embroidery cloth 5 with an embroidery thread along the contour of the applique, and so-called applique embroidery is executed.

Next, at the end of applique embroidery, the process proceeds to step 10 to determine whether or not the entire embroidery work on the embroidery cloth 5 has been completed, and the process from step 2 onward is repeated while determining "NO". To And Step 4
When it is determined to be "NO", the process proceeds to step 8 to determine whether or not to perform the drawing process of the picture pattern, and when it is determined to be "YES", the process proceeds to step 9 to execute the discharge control of the resin paint by the dispenser 15. I do.

That is, in the paint discharge control in step 9, the resin paint is discharged (applied) using the dispenser 15 to the drawing position of the picture pattern predetermined by the embroidery data. By operating the frame moving mechanism 7, the embroidery cloth 5 is automatically moved in the X-axis direction and the Y-axis direction together with the embroidery frame 8, and the portion corresponding to the drawing position on the embroidery cloth 5 is moved to the discharge port of the dispenser 15. 15A is faced up and down.

At the same time, the actuator 17 for discharging the paint is operated, and the discharge port 15 of the dispenser 15 is operated.
A is made to approach the embroidery cloth 5, and the resin paint in the dispenser 15 is discharged from the discharge port 15A by the piston in an appropriate amount. Then, in this state, the embroidery cloth 5 is moved along with the embroidery frame 8 by the frame moving mechanism 7 to form a picture pattern at the drawing position of the embroidery cloth 5 based on the embroidery data. The data for creating the picture is also stored in advance in the embroidery data together with the pattern data and the like.

After the process of step 9 is completed, the process also proceeds to step 10 to determine whether or not the entire embroidery work on the embroidery cloth 5 has been completed. By repeating the process, a pattern pattern using embroidery thread is formed on the embroidery cloth 5 so as to create an embroidery pattern around the applique or the picture pattern. On the other hand, when it is determined as "YES" in the step 10, the embroidery control process is completed assuming that the entire embroidery work on the embroidery cloth 5 is completed.

Thus, according to the present embodiment, the dispenser 15 for paint and the dispenser 14 for adhesive are arranged on the table 3 of the embroidery machine so as to be in parallel with the sewing machine head 4.
