Abstract

PURPOSE:To remarkably increase the amount of a housed string, etc., increase the embroidering speed and improve the embroidery efficiency. CONSTITUTION:This zigzag embroidery machine is constructed by rotating a rotating frame holding an embroidery cloth in an extended state on a moving frame 13 at a required rotation angle with a frame rotating motor 17 and rocking an embroidery needle 10 installed in a sewing machine head 7 in the direction of the (y)-axis at a required shogging width. Furthermore, a bobbin 18 for housing a string 20 in a wound state is rotatably provided through a supporting bracket 19 on the sewing machine head 7 and a guide 21, extending to the vicinity of the needle point of the embroidery needle 10 and leading the string 20 wound around the bobbin 18 onto the embroidery cloth is provided on the side of the tip of the sewing machine head 7. The string 20 led from the bobbin 18 through the guide 21 onto the embroidery cloth is then sewn on the embroidery cloth with the embroidery needle 10 rocked at the required shogging width. The rotating frame is rotated while moving the moving frame 3 to curve the string 20 in an optional direction on the embroidery cloth. Thereby, the embroidery of the string 20 forming an optional pattern is realized.

By the way, in the above-mentioned prior art, the string-shaped bobbin is rotatably provided on the outer peripheral side of the needle shaft, and the bobbin together with the string-shaped guide is centered around the needle shaft by the motor. Since the bobbin for the string-like body is interposed in a relatively small space between the head of the embroidery machine and the embroidery cloth, the embroidery pattern on the embroidery cloth can be visually confirmed. Sometimes the bobbin gets in the way,
There is a problem in that the bobbin cannot be made large and the amount of the cord-shaped body that can be stored in the bobbin in a wound state (the total length of the cord-shaped body that can be wound around the bobbin) is limited.

Further, ribbons, tapes, wools, gold threads, silver threads, etc. are usually used as the string-like body, but since the bobbin for the string-like body has a structure in which it is driven to rotate about the needle shaft by a motor, The width, thickness, thickness, hardness, etc. of the string-shaped body are limited, and the type of the string-shaped body cannot be freely selected, and in order to balance the rotation of the bobbin, the bobbin must be rotated at a high speed by a motor. Therefore, there is a problem in that the rotation speed of the bobbin is limited, which limits the overall embroidery speed, making it difficult to increase the embroidery speed.

Next, in step 6, it is judged whether or not the embroidery pattern of the string 20 is finished. When it is judged "NO", the process returns to step 5 and the needle drop points Sk and Sk illustrated in FIG.
'Continue with the subsequent embroidery. Then, for example, when the pattern is finished, it is determined to be "YES" in step 6 based on the end function in the hand movement data. Therefore, it is determined in step 7 whether or not the power OFF switch 32B is pressed, and it is determined to be "YES". If so, an embroidery ending operation such as sewing, thread trimming, or movement of the end point is executed to end the processing operation.

When it is judged "NO" in step 7, it returns to step 4 and judges whether or not the start switch 37 is opened. For example, the embroidery cloth 16 is replaced to embroider the same pattern, and the operation is restarted. When the switch 37 is opened, it is determined to be "YES" in step 4, and therefore the processing from step 5 onward is repeated. On the other hand, when embroidering a different pattern or re-inputting other hand movement data from a different floppy disk, the procedure returns to step 1 and the operation preparation is started again. Then, when you want to change the speed, manually adjust the variable speed knob 42,

As described in detail above, according to the present invention, the rotary frame for holding the embroidery cloth in the stretched state is rotated on the moving frame by the rotation source at the rotation angle θ, and the embroidery machine head is embroidered. The needle is oscillated with the swing width W, and the string-shaped body is guided toward the vicinity of the needle tip of the embroidery needle from the string-shaped body storage portion provided apart from the embroidery needle onto the embroidery cloth via the string-shaped body guide. Therefore, the string-like body can be easily sewn on the embroidery cloth by the embroidery needle that is moved with the swing width W,
By rotating the rotating frame at the rotation angle θ while moving the moving frame, the cord-like body can be curved in an arbitrary direction, and the cord-like body can be embroidered with an arbitrary pattern.
