Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an embroidery sewing device that is used in conjunction with a sewing machine to automatically perform embroidery sewing.

Conventionally, this embroidery sewing device includes an X-axis drive system that reciprocates the embroidery frame in a certain axial direction The Y-axis drive system reciprocates in direction Y, and external (for example, card reader, magnetic tape playback device) or internal (Read-only memory: ROM or random access memory: R
AM) is equipped with a central control unit that reads embroidery stitch data and supplies it to the X-axis drive system and Y-axis drive system to control the position of the embroidery frame.

The central control unit is now a central processing unit (CPU) or microprocessor, which occupies the main part of a microcomputer, and also has sewing control data for various embroidery patterns stored in ROM in advance. An embroidery sewing device has been proposed in which an I group is specified by an input switch, and thereafter sewing control data is sequentially read out from a ROM in synchronization with the sewing operation of the sewing machine to automatically perform embroidery sewing.

Recently, high-density and high-capacity ROMs are available, so by storing many different embroidery patterns in advance in the ROM, the user can select from a large number of embroidery patterns.

However, in embroidery sewing, it is desirable to sew each pattern with each thread and create one colorful pattern by combining these patterns, but in order to do this, it is necessary to simply synchronize with the sewing operation of the sewing machine. In addition to moving the embroidery frame in the X and Y directions, it is also necessary to change the sewing thread so that after sewing one pattern with thread of one color, another pattern is sewn with thread of a different color. For one multicolor embroidery stitch, it is necessary to divide the sewing control data into blocks of different color thread spots, add a break between the blocks, and replace the thread every time one block of data is read out.

The present invention provides an embroidery sewing device that stores embroidery sewing data in advance in a high-density storage device such as ROM and/or RAM, and performs automatic embroidery sewing by sequentially reading out the data in synchronization with the sewing operation of the sewing machine. The purpose is to inform the user of the thread change timing and information about the next thread to be set, thereby making it easier for the user to change the thread.

First, it is shown in FIG. 7a.

The embroidery sewing control operation and display control operation based on the data in the ROM 46e will be explained.

The user turns the input switch S by opening the input switch S1o.

-89 is closed, the system 46 is given the read start address of the ROM 46e which designates a specific unit of embroidery stitch data, and this is displayed on the numerical display unit 44.

When the user closes the switch S1□, one of the indicator lights LL is turned on based on the first data of the starting end address, that is, the thread color specification information, and the next embroidery stitch data and the output code of the converter 5L53 are sent to the cPU46d. Based on the comparison result, the motors 11 and 12 are driven to position the embroidery frame 4 until the comparison value becomes zero.

Then, the user sets the thread of the color indicated by the lit thread color indicator (LL) in the sewing machine.

When the user closes the switch Stt, the sewing machine motor 55 is urged to rotate.

For each stitch, the read address of the ROMJ 6e is incremented based on the output pulse of the reed switch 57 and displayed on the numerical unit 44. It is carried out during the period when it is absent.

When one block of data has been read from the ROM 46e in this way, the sewing machine motor 55 is stopped based on the end display information in the last data of that block, the end indicator LF is turned on, and the next A thread color indicator light (LL) indicating the color of the thread used to sew the pattern is lit.

At this time, the display on the numerical display unit 44 indicates the write address of the last data (end display information and thread color specification information) of one data block, and this indicates the end of the data block and the thread color to be sewn with the next block data. Since there is a one-to-one correspondence, it is also thread change information.

When the user sets the thread of the color specified by the illuminated indicator light (LL) into the sewing machine and closes the switch S11,
The embroidery is resumed based on the data of the second block.

Through such operations, embroidery stitches are further performed using threads of various colors based on the data of the third, fourth and fifth blocks.

Since this embodiment is set to use a maximum of five colored threads, the end display information and the activation of the number display unit 44 for the zero display "0OOOOOOOOJ" are included at the end of the data of the fifth block. information is included, and when sewing based on the data of the fifth block is completed, zero is displayed on the display unit 44 (during sewing, the ROM 46e
read address is displayed).

Note that when the number of thread colors is less than five, zero display information is included at the end of the data of the last block.

Next, a write control operation for storing pattern sewing data in the RAM 46b in response to the closing operation of the switch 813, shown in FIG. 7b, will be explained.

When the user closes the input switch S1□, the motor drive circuits 50 and 52 are commanded to release the motor lock, thereby allowing the motors 11 and 12 to rotate by external force.

Next, the user switches to Switch S.

When the user closes one of the thread color designation switches 815 to S19, then holds the writing instrument 39 and places its tip at a desired position, and closes the switch 813, the output of the converter 51.53 at that point At the same time that the code is written to the start address of the RAM 46b and the write address is next incremented, a single stitch energizing signal is issued to the sewing machine motor drive circuit 54, and only one stitch of the cloth in the embroidery frame 4 is sewn. be exposed.

When the user moves the writing instrument 39 to the next stitch position and closes the switch 813, the converter 5L at that time
The output code of 53 is stored in the RAM 46c, and one more stitch is sewn on the cloth.

Thereafter, the user continues this operation until he finishes drawing the embroidery pattern he intends under the writing instrument 39.

When you have finished drawing the pattern, set a different color of thread in the sewing machine, and if necessary, replace the writing instrument 39 with another color (corresponding to the thread color) and press the thread color designation switch (S) to indicate that color.
□, ~819) and close the switch S20.

By temporarily closing the switch 820, new thread color designation information and end display information are written to the RAM 46b.
The write address is then incremented.

Next, the writing instrument 39 is used again to repeat the data writing operation described above.

When the data writing for each thread of the desired color is completed in this way, the switch S1□ is returned to the open position.

As a result, zero display information is written into the RAM 46b.

When this operation is finished, the RAM 46b has ROM
As in 46C, embroidery stitch data is stored.

Further, an embroidery pattern is drawn on the paper directly below the writing instrument 39, and the pattern is embroidered onto the cloth of the embroidery frame 4.

The data thus stored in the RAM 46b is retained by the battery backup circuit 46c even when the main power is turned off.

Next, the embroidery stitch control operation and display operation based on the pattern stitch data stored in the RAM 46b shown in FIG. 7a will be explained.

The user closes switch SIO and switches S.

When -89 is closed, the read start address of the RAM 46b is designated to the system 46.

Further, when the switch Stt is closed, automatic embroidery is performed based on the data read from the RAM 46b, similar to the above-described continuous embroidery (reading data from the ROM 46e).

Since the embroidery hoop drive mechanism shown in FIG. 1 is simple and compact, the force required by the user to move the writing instrument 39 is relatively small, but it requires significantly more force than for normal writing.

FIG. 4 shows an embodiment in which this is improved.

In this, user-operated potentiometers 58.59 and analog-to-digital converters 60, 61 are added to convert their outputs into digital converters, and the output code of the converter 60.61 is input/output. device 46a.

Furthermore, an input switch S14 for manual operation and automatic drive is added.

In addition to the various control programs that are included in the embodiment shown in FIG. An operation control program is stored that controls the position of the embroidery frame 4 by setting the position control target value of the motor 12 to the position control target value of the motor 12 and the output code of the converter 61 as the position control target value of the motor 11. In FIG. 5, the potentiometer 58. 59 is shown.

In this embodiment, two levers 62 are provided so that potentiometers 58,59 can be operated by one lever 62 at a time.

3, each rotation axis has an arcuate arm 6 orthogonal to each other.
4.65 is fixed to one end.

The other end of each arm 64, 65 is pivotally connected to the case 63 with a pin.

Therefore, when the arm 64 does not rotate, the rotation axis of the potentiometer 58 rotates, and when the arm 65 rotates, the rotation axis of the potentiometer 59 rotates.

Slits are made in the arms 64 and 65, and a joint lever 66 passes through these slits, and one end of the joint lever 66 is fixed to a support base 67 so as to be rotatable within a solid angle of 180 degrees. .

An end of a lever 62 is fixed to the other end of the joint lever 66 so as to be rotatable within a solid angle of 180°.

The leg portion of the lever 62 slidably passes through a ball 68, and the ball 68 is rotatably held by the case 63.

With this combination, by swinging the lever 62 back and forth, left and right, the shafts of the potentiometers 58 and 59 are rotated.

The writing instrument 39 and the embroidery frame 4 automatically move in response to the operation in step 2.

Therefore, in this embodiment, the switch 814 is closed and the switch S1□ is closed.

After specifying the RAM write start end address to the system 46 by operating -89, operate the lever 62 to
By repeating the operation of moving the tip to the desired position and temporarily closing the switch 813, the figure drawn with the writing instrument 39 is sewn onto the cloth with a single stitch, and the sewing data is stored in the RA.
It is stored in M46b.

In this way, when inputting original pattern data, the embroidery frame 4 is automatically driven.

In this embodiment, since the motors 11 and 12 are driven and controlled so that the output codes of the converters 51 and 53 match the output codes of the converters 60 and 61, the conversion is made when the lever 62 is not operated. The output codes of converters 51 and 53 and converters 61 and 60 are respectively equal.

Therefore, at the time switch SI3 is closed, either of the outputs of converters 51.53 and 61.60 can be changed to 1M46.
It may be stored in b.

Which output is stored is determined by the operation control program of the ROM 46e.
