Description

DETAILED DESCRIPTION OF THE INVENTION Invention 1 () In addition to attaching a string-like body such as a connected body of ribbons, beads, and sequins to a sheet, for example, cloth, in an arbitrary pattern, 31.11χjail: sewing cloth with thread in any embroidery pattern that follows the body
Concerning a method of controlling a sewing machine.

Conventionally, when attaching a string-like object to cloth, so-called tape attachment, the center of the tape is sewn with thread along the trajectory of the tape that corresponds to the pattern, so not only is there no bulge in the tape, but the design effect of the thread is also small. However, by attaching tape to cloth, there is a limit to the patterns that can be created, and not only can you not create many designs, but you can't even get good designs. The object is to eliminate the above-mentioned conventional drawbacks.

Next, the configuration of an embodiment of the present invention will be explained with reference to the drawings.

At a position above the throat plate 3 of the table 2 to which the bobbin thread supply hook 1 is attached, a needle bar 6 to which a needle 5 that reciprocates in the needle hole 4 of the throat plate 3 is attached is attached to a fixed pulley 8 of the frame 7. A reel holder, in this case a string-like body (hereinafter referred to as tape), is attached to a rotatably attached guide bush 9 so as to be reciprocally movable via an external power, and a fixed pusher 8 has a reel holder formed with a gear 10. )" A reel holder 14 to which a reel 13 with a bobbin 12 wound with a bobbin 12 wound with 11 f is attached in a removable and rotatable manner is rotatably attached with movement in the axial direction restricted, and this reel holder 14 and a guide button The locking piece 9 is a locking piece which is fastened with bolts 15 to the reel holder 14. When the locking piece 6 is loosely fitted into the key groove 17 formed in the guide pusher 9, it is fixed so that it cannot move relative to the other in the circumferential direction. ing.

Further, a guide piece 18 for guiding the tape 11 from the bobbin 12 to the needle hole j position on the throat plate 3 is attached to the tip of the guide bush 9 via a bolt 19. A cloth 20 to which the frame is attached is fitted into the frame 21 and is attached so as to be movable in the X-Y plane direction together with the frame support 22.

Next, FIG. 2 shows the converter ji1 in this embodiment.
3 is a system block diagram of rMI, in which address bus line 26 data bus line 27d from CPU 25: memory elements ROM 28, RAM 29, and respective driver circuits 30.3
1 and a frame drive mechanism for moving in the X-Y direction via pulse motors 32 and 33. 34, while connected to gear 10, guide bush 9 is moved by a string via driver circuit 35 and pulse motor 36. Guide drive I/F 37 and operation panel 3 for rotating the shaped body 11 in accordance with the feeding direction
8 operation panel I/F 39, a main shaft drive "/F 42 that drives the main shaft connected to the needle bar 6 via a driver circuit 40 and a motor 41, and reads embroidery data including tape 11 attachment via a tape reader 43. Tape 'J-ta■/F
44.

Next, FIGS. 3 to 5 are control flowcharts of this embodiment. When the power switch is turned on, the system first performs an initialization operation in the initial routine of step 101, and then sets initial values. At the same time, the process moves to the sewing machine main shaft stop processing routine in step 102, and after reading various conditions necessary for embroidery machine processing such as color change and embroidery pattern selection set on the operation panel 38 in step 103, the process proceeds to step 104. It is determined whether the manual frame movement switch is ON, and if it is ON, a frame drive pulse is output to each pulse motor 32, 33 in response to the operation of the frame movement switch in step 105, and the manual frame movement switch is not operated. In step 106, it is determined whether the embroidery pattern selection switch is ON, and if it is ON, step 107
Register the stinging pattern selected in the RAM29,
After the embroidery pattern selection switch is in the OFF state and after registration, other conditions necessary for embroidery machine processing are read in a step not shown and registered in the RAM 29, and then step 108
Determine whether the start switch is ON.

If the start switch is ON, the system returns to the main routine and moves to the sewing machine spindle operation processing routine in step 109.After starting the sewing machine spindle operation in step 110, the embroidery data tape read request flag is turned ON in step 111. If it is ON, in step 112, for example, one stitch of data is transferred to the tape reader 4.
3, and in step 113 it is determined whether the read data is a stop or end code. If YES, a stop or end flag is set in step 114, but after NO and the flag is set, the read data is embroidered in step 115. After registering the embroidery data developed according to the pattern in the RAM 29 and setting the number N of stitches corresponding to the developed embroidery data in the development counter, the tape 11 is
It is determined whether the winding shaft drive timing is ON, and if YES, the winding shaft drive pulse is output to the pulse motor in step 117, and a winding shaft output completed flag is set, and if NO or after the flag is set, the frame is set in step 118. driving x
11411-Determine if Y-axis timing is ON, YES
In this case, in step 119, the X-axis and Y-axis drive pulses are output to the pulse motors 32 and 33, and the It is determined whether there is a completed flag, and if YES, in step 121 the X-axis
It is determined whether there is a Y-axis output performance flag, and if YES, the winding shaft, X-axis and Y-axis output performance flags are reset in step 122.

The next development embroidery data is set and the development counter is decremented, and in step 123 it is determined whether the development counter is 0. If YES, in step 124, the tape read request flag for the 1st stitch 1j data is turned on,
In step 125, it is determined whether the stop or end flag is set, and if YES, the main shaft of the sewing machine is stopped in step 126, the main routine e is returned to, and the stop processing is executed.
In the case of 120, 121, 123 and the previous i1: after performing other embroidery machine processing in the step of the person not shown, the contents of each glaze operation on the operation panel 38 are read in step 127. , in step 128 it is determined whether the stop button is ON, and if YES, the process returns to the main routine and executes the stop 1 process;
In the case of NO, the sewing machine main shaft operation processing routine is repeated and the stitching with IC tape is performed according to the embroidery data 1d! I do.

That is, as shown in FIG. 6, Iflle can attach the tape 11 with any embroidery pattern and any trajectory.
When the tape 11 is made of beads or sequins that cannot be penetrated by a needle, arbitrary tape 11 can be attached by embroidering across the beads or sequins.

Next, the effects of the present invention will be explained.

When attaching a string-like body to cloth, commonly called taping, the present invention provides a cord-like body that can be fed out in any direction around a needle bar, and also adjusts the position of a frame body that supports the cloth and the shape of the string. A method for controlling an IS sewing machine that controls the direction in which the body is fed out according to a preset pattern.

As a result, the present invention not only allows for a wide range of tape-attached designs, but also has the effect of making the tape-attached designs even more appealing by changing the embroidery pattern along with the tape attachment.
