Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for creating sewing data for an automatic sewing machine, and particularly for an automatic sewing machine that uses software to calculate and display the sewing cycle time based on the sewing data after creating the data. The present invention relates to a sewing data creation method.

[Conventional technology]

Conventionally, the device shown in Figure 4 has been used as this type of sewing data creation device. In the figure, the data creation device includes an input tablet board 1 and a stylus pen 2. By bringing the stylus pen 2 into contact with a desired position on the input tablet board 1, the input tablet board 1 writes data corresponding to the contact position. An input signal can be obtained.

As shown in FIG. 4, the input tablet board 1 is divided into two sections, including a pattern input section 3 into which a desired sewing pattern can be input as an image, and a plurality of input terminals arranged on the side of the pattern input section 3. When the stylus pen 2 touches an arbitrary position of the pattern input section 3, a signal corresponding to the coordinates in the pattern input section 3 can be output. By touching 2 to any position of the operation key displayed on the operation key manual section 4, a predetermined manual operation of the operation key can be performed.

Further, as is clear from FIG. 4, the data creation device includes a display panel 5 for displaying the operation procedure of the operation keys, and a CRT display 6 for displaying all the kimono patterns input to the pattern input section 3. Therefore, it becomes possible to instruct the operation procedure for creating sewing data to the operator 1, and to monitor and check the created sewing data on the CRT display 6 before loading the created sewing data into the storage medium 9.

The display panel 5 in the embodiment includes 1) -RO in a part thereof.
An M socket is provided, which is described in the example. ! A P-ROM used as a medium is installed in the socket, and eight sewing data are stored in the P-ROM.

FIG. 5 shows a block diagram of the configuration of a conventional sewing data creation device a for an automatic sewing machine. In the figure, the data creation device e made by the company temporarily stores the XY coordinate data from the input tablet board 1 as relative value data showing the amount of change in XY for each line, and also has an RA with a working memory of the CPU.
M9. An image RAM 10 that temporarily stores the XY coordinate data as image data, a ROM 11 that stores a program for transferring and storing relative value data stored in the RAM 9 to the P-R0M 8, and a CRT controller 12 that controls the CRT display 6. These include the CPU
13.

Then, the XY coordinate data from the input tablet board 1 is temporarily stored in the RAM 9 as the relative value data, and is also temporarily stored in the image RAM 10 as image data. XY coordinate data from the board 1 can be stored in the RAM 9. Then, when all the XY coordinate data input operations are completed, the RAM 9
The relative value data stored in is stored in ROM1 by CPU13.
The data is transferred and stored in the P-ROM 8 according to the program stored in advance in the P-ROM 8. Therefore, by automatically controlling the cloth or the needle according to a predetermined sewing pattern based on the sewing data stored in the P-ROM 8, it is possible to automatically sew a desired sewing pattern.

[Problem that the invention seeks to solve]

However, in the conventional apparatus, there is a problem in that the sewing data cannot be sewn until the sewing data is written into the F'ROM and the sewing machine is attached to an automatic sewing machine and the automatic sewing machine is operated.

This invention was made to solve this problem, and is there a way to find out the cycle time before driving? The purpose is to get something.

Means for Solving Problems c] In order to solve the above problems, this invention
The sewing data stored in M is read out for each stitch, and the sewing speed determined according to the sewing length is determined.The time for each stitch is accumulated, and the
The time for attaching and detaching the workpiece is added between 9 and 9 and displayed as the cycle time in one sewing data.

[Effect]

Cycle time is calculated and displayed.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. The hardware configuration is the same as the conventional one shown in FIG. Figure 2 shows the inside of the RAM for relative value data, 20 to 2
3 shows one example of data made by i, and 20.21 shows memorized data (5OI) for actually rotating the sewing machine to form a seam.

21 is the jump feed data (
Fal, Fo2-van) % 23 is data indicating the end of sewing data, 24 is a counter memory area used for the program of the present invention which will be described later, FIG. 1 is a flowchart for calculating the cycle time suitable for the present invention, 3
This figure is a subroutine that is used in the flowchart shown in FIG. 1 and increments a predetermined counter depending on the stitch length of the correct data. The counter memory area 24 stores SCI to 6. FC,CT
, W.S.

A memory area named WR is reserved.

Next, the operation will be explained. When the electronic sewing machine is operated based on the sewing data shown in FIG. 2, the sewing data S 01
-8 On, or 1 each shown in 811-8in.
The machine is designed to operate at a speed corresponding to the number of stitches based on the data for each stitch, and the time required for one stitch is known in advance. When executing the stitch time between STI to ST6 and the blank feed data FOI to FOn depending on the stitch length, the time required to move one data is defined as FT. The installation time and removal time of the workpiece are also known, and let these times be WS and WR, respectively.

Now, if the leather data is input as shown in Figure 2, the RO
The program stored in MI 1 performs the processing shown in FIG. In FIG. 1, first, in order to set the counter memory area 241j:O in the RAM 9, step 10 shown in FIG.
Processes 0 to 102 are performed. Next, write the starting address Nt of the RAM 9 where the sewing data is written, as shown in step 103, to the HL register in the CPU 15 that specifies the memory address, and as shown in step 104, write the starting address Nt of the RAM 9, which is specified in the HL register as shown in step 104. Data for one stitch of sewing data is read into the A register in the M'tcPU 13, and in step 105 it is determined whether or not it is jump feed data, and if it is jump feed data, the jump feed data counter FC is set by 1 as shown in step 106. Count up.

If it is not jump feed data, it is determined in step 107 whether it is wrapping data or not, and if it is sewing data, an SC subroutine for counting sewing data is executed as shown in step 108. Here, the entire SC subroutine will be explained with reference to FIG.

First, in step 200, the stitch length of the sewing data is set to 6m.
Determine whether it is greater than 61111. ! : If the stitch count is larger than 6, one count is added to the counter SC6' for stitches larger than 6 in step 201, and if it is less than 6 stitches, the following are determined as 5 ms, -1 m, 3 m, and 2 stitches, and the respective ranges are set. The counter 5c(n) that fits
Add count.

Now, returning to 70-cheat in Figure 1, step 1
If it is determined in step 07 that it is not sewing data, the process proceeds to step 109, and it is determined whether or not it is end data. If it is not end data, one step is added to the HL register in step 110, and the process returns to step 104. If steps 106 and 108t are completed, proceed to step 1101'l:. This processing flow includes sewing data 20, jump feed data 21. The execution is executed for sewing data 22, and the number of jump feed data in the sewing data is set to FC. If the data corresponds to each length range of the sewing data, the process proceeds to step 111, and the number of jump feed data FC and jump feed 1 are set. Time required to move needle minute data FT
and the number of pieces of sewing data 5C(n) and the time required for one stitch 5T(n), and the sum of the six values and the workpiece attachment and removal times WS and WR are written in CT. This CT value becomes the cycle time of the sewing data. Next, in step 112, the value of this sewing cycle time CT is displayed on the LED display board 14, so that the sewing data creator is informed of the entire cycle time.

Although the above is a cycle time calculation for one sewing, it is also possible to calculate for one day.
In this way, it is possible to obtain the operating rate, expected trading volume, etc. for one day.

〔Effect of the invention〕

As explained above, the present invention has the effect of facilitating work management because the cycle time is determined using the sewing data sound before the start of sewing.
