Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a device for creating sewing information for a sewing machine.

[Conventional technology]

Among industrial electronic sewing machines, automatic sewing machines have been put into practical use that automatically sew cloth in a desired sewing pattern by driving the cloth or needle based on a memory device. - The track record information is held in the storage medium in the storage device N,
By replacing this storage medium, different sewing patterns such as f and lI can be easily made. c-(
There is. As a storage medium.

Semiconductor memory, magnetic cards, etc. are generally used.

Control information for the movement of the sewing machine is held in this in accordance with the operating order of regrets. The structure of control information usually consists of control commands for the relative displacement of the needle and cloth for each stitch of the sewing machine that forms a sewing pattern, the sewing speed, and other movement control commands, and the control information for one sewing pattern consists of these 1 It is formed as a set of control commands for each needle.

Therefore, this automatic sewing machine can create the desired sewing pattern! l
In order to perform all the I-stitches, it is necessary to create control data corresponding to the sewing pattern and store it in a predetermined storage medium.

Conventionally, is this persimmon device shown in Figure 1?A? −

By drawing a desired sewing pattern on the tablet digitizer OQ with the cursor (13), the predetermined pattern data is written from the PROM writing circuit (1υ) through the gate (44I) under the control of 0PUQ41 in FIG. Write the sewing pattern data signal in °C to the FROM to be formed,
This is attached to the FROM cassette (4) to the sewing machine control device to drive the sewing machine.The FROM is attached to the PRO, M socket. The various modes and the operator HA at the time of this input are displayed on the LED display panel @ via the gate 1441 as data 10. The input data from the tablet digitizer 4 via the gate decoy is FRO by the 0PUQ41.
The program to write to M is system program RO.
Mc! CPUQ4 performs processing according to this program, and input data from the tablet digitizer song is stored in data memory R consisting of RAM.
This stored value is temporarily stored in the AMCJ 41, and this stored value is stored as relative value data indicating the XY coordinate data of the tablet-digitizer 4 by the amount of change in MY of each stitch. A CRT for monitor display (to) to monitor the input data of the tablet digitizer 4 when writing it to the 2f'ROM.
is provided, converts the data in the cptr (141 to data memory RAM1.'4) into data for one image, and sends the data to the image data memo IJ RA via gate 03.
After converting the digital value to an analog value (voltage) using the D/A converter (b) and cm using the DMA controller α, the CRT control circuit +41 converts the digital value to an analog value (voltage).
The stitch pattern figure is displayed on the RT (4), and manual labor is possible while the operator confirms it with one image.

Since the conventional sewing data creation device for sewing machines is configured as described above, when converting the control signal of the pattern data written in FROM, it is necessary to convert the control signal of the pattern data written in FROM.

There is a drawback that writing must be performed in the graphic input FROM.

[Overview of the invention]

This invention was made in order to eliminate all the drawbacks of the conventional ones as described below.
By connecting 111 with cable 7 and providing a shareable Otori M rero area, it is possible to input a control signal to any position of the created stitch pattern data or to delete the signal that has already been input. The object of the present invention is to provide a sewing data creation device for a sewing machine.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be explained with reference to the drawings. In Fig. 3, 6I is a data memory RAM attached to a conventional sewing data creation device, and pRoMVc is written at the same time as pattern data is created. The same pattern data is written by cPUn4 via the gate. (G) is a stack memory RAM in which the needle position data from the sewing machine side is stored in the sewing machine controller + 4 (L) via the gate 6 and into the gate 64. Connected.CPU0
4 is the XY input from the tablet digitizer IIQ
Convert coordinate values to sewing data for sewing machine and store in data memory RA
It is stored in the Mα4 and at the same time stored in the data memory lJRAM 511 shared with the sewing machine. others.

(The actual data is also stored in the data memory RAM@.

As before, a pattern is drawn on the CRT (4). The sewing machine side is connected to this data memory RAM61 through gate Cia.
It becomes possible to perform sharp sewing in the same manner as when normal FROM data is read by the sewing machine control circuit t41. Gate 63 and Gate (Gate) are the sewing machine side and the data creation device side, which is X on the hardware side.
Switching between input and output is performed. All of these operations are performed under the control of the 0PU 941 by the system program on the sewing data creation device side.

FIG. 4 shows an example of one sewing data. - is for sewing machine
G4. The machine moves to day and m, cuts the thread at -, and then returns to Ill with a blank feed.

The sewing data bit structure at this time is shown in FIG. What is shown in FIG. 5 is the relative value of the data bit configuration,
An example of actual use is as follows.

Equivalent to one stitch = 2-byte feed amount (5 bits) = θ ~ 31 Sewing machine control code - even address (bs・bs) = (o・1)... Even address of sewing machine rotation (bs・bs) = (1・1) - Air feed speed code odd address (bs・bs)=(o・0) Sewing machine rotation Low speed odd address (bs・bs)=(o・1) Sewing machine rotation Medium/high speed odd address (bs・bs)= (1.0) Sewing machine rotation Medium/low speed odd number belt (bs.bs) = (1.1) Sewing machine rotation The crystal speed sewing machine control device i41 reads the sewing data and drives the automatic sewing machine.

In addition to the sewing data representing the amount of movement, there are various special command codes, which are shown below.

Other various codes (2-byte configuration) 1, (40H,00)...Thread trimming code 2, (80
H, On)... Intermediate stop code s, (OOH,00)
・・Reverse presser foot drive code 4, (011(,00)・・
・Second origin code s, (oo, oo)... End code 4 If you want to manually enter the special code, for example, a mid-stop code, into the already created sewing data at the position shown in Figure 10, use the sewing machine control on the sewing machine side. The needle is moved to this position by the device at 14Q, and the address is stored in the full data memory RAM (g). Then, the operator manually enters a seat position value indicating that the midway stop F code is to be input using the tablet digitizer 4.

Data memory RhMc corresponding to apUQ4ft!
4. This instruction is stored at the address of M, and the data at that position is slid two bytes at a time to the rear address IC.

Similarly, when deleting the verification code, manually delete it using the tablet's own digitizer (1 [I), and slide the data below the command code to the address where the command code was located.

Furthermore, this also changes the image data memory RAMCA at the same time, making it possible to form a new image.

All of these are controlled by the system program (c).

FIG. 6 shows the image data bit structure. This embodiment has an X-axis, a Y-axis, and a 12-bit configuration. and,
The valley data bits are used as follows.

Image data X-axis' :Image OFF [Effects of the Invention] As described above, according to the present invention, without using FROM,
Direct flAM allows you to check the operation of the output part that assists sewing during actual sewing.

Since the data that instructs this operation can be manually or deleted at any position, it has the effect of greatly streamlining the pattern input operation.
