Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sewing data creation device for an automatic sewing machine, and more particularly to an improved sewing data creation device for writing sewing data for controlling cloth feed of an automatic sewing machine into a storage medium.

Automatic sewing machines are well known that store sewing data programmed in advance in a storage device, automatically control the cloth or needle according to a predetermined sewing pattern based on this sewing data, and automatically sew a desired sewing pattern. It has been widely put into practical use as industrial electronic sewing machines and the like.

The sewing data is written in a storage medium in the storage device, and by exchanging this storage medium, it becomes possible to arbitrarily select and sew a different sewing pattern, which saves labor and increases the sewing speed of the sewing machine. It can greatly contribute to improvement.

A semiconductor memory such as a P-ROM, a magnetic card, or the like is generally used as the storage medium, and desired sewing patterns, sewing speeds, and other control data are stored and held in the storage medium in accordance with the sewing operation order. Normally, the sewing pattern consists of control commands for the relative displacement end of the needle and cloth for each stitch of the sewing machine that forms the sewing pattern, the sewing speed, and other movements, and the control information for one sewing pattern is It is formed as a set of these control commands for each stitch.

In this type of automatic sewing machine, in order to automatically sew a desired sewing pattern, it is necessary to create sewing data corresponding to the sewing pattern and write it into a predetermined storage medium.

Conventionally, a device shown in FIG. 1 has been used as this type of sewing data creating device. In the figure, the data creation device includes an input tablet board 10 and a stylus pen 12, and the stylus pen 12 is connected to the input tablet board 1.
By making contact with the desired position of 2, a write input signal corresponding to the contact position can be obtained from the input doublet board 10.

The input tablet board 10 has a board surface divided into two parts as shown in FIG. 7, and includes a pattern input section 14 that can input a desired sewing pattern as an image;
When the stylus pen 12 touches an arbitrary position on the pattern input section 14, it outputs a signal corresponding to the coordinates in the pattern input section 14. can output,
Further, each time the stylus pen 12 touches an arbitrary operation key position displayed on the operation key input section 16 surface, a predetermined operation key can be manually operated.

Further, as is clear from FIG. 1, the data creation device includes a display panel 18 that displays the operation procedure of the operation keys, and a CRT that displays the sewing pattern input to the pattern input section 14.
It includes a display 20, and allows an operator to be instructed on the operating procedure for creating sewing data using a display panel 18, and to monitor and check the created sewing data on the CRT display 20 before writing it to a storage medium.

The display panel 18 in the embodiment has P-RO in a part thereof.
An M socket 22 is provided, and a P-ROM 24 used as a storage medium in the embodiment is connected to the socket 22.
The sewing data is P-R01VI 2.
/4 is written and stored.

FIG. 2 shows, in block form, the configuration of a conventional sewing data creation device for an automatic sewing machine. In the figure, the sewing data creation device temporarily stores the xY coordinate data from the input tablet board 1ζ10 as relative value data representing the xY change ω of each stitch, and the RAM 26 temporarily stores the xY coordinate data as image data. Image RAM28, RAM26
ROM3'O and C in which a program for transferring and storing the relative value data stored in P-ROM24 is stored.
CRT controller 3 that controls RT display 2o
2, which are controlled by CI) U 34.

The xY coordinate data from the input tablet board 10 is temporarily stored in the RAM 26 as the relative value data, and ii! ! It is temporarily stored as image data in the i-image RAM 28, and as a result, the input tablet board 1 can be input while checking the monitor on the CR display 20.
The xY coordinate data starting from 0 can be stored in the RAM 26. When the input operation of the xY coordinate data is completed, the relative value data stored in R'A 426 is transferred and stored in P-ROM'24 according to the program stored in advance in CPIJ34's ROM 30. Ru.

Therefore, by automatically controlling the cloth or needle according to a predetermined sewing pattern based on the sewing data stored in the P-ROM 24, a desired sewing pattern can be automatically sewn.

However, in the conventional sewing data creation device (I3), the desired sewing pattern is written in advance on a section vapor, etc., and the coordinates of the point of each stitch are read one by one according to the sewing order and converted into data. Since this was done by writing the coordinates of the stitches into a storage medium, reading the coordinates of the stitches was inaccurate and errors were likely to occur in the sewing pattern.
- It takes a lot of time and effort to create sewing data, and sewing data for complicated sewing patterns cannot be easily created. In particular, when sewing (for example, sewing patterned fabric onto clothes) or sewing the edges of parts (for example, sewing pockets onto clothes), the outer shape of the part should be separated from another section of paper, etc. As a result, sewing data cannot be created accurately and easily for parts with many curved parts.

The present invention has been made in view of the above-mentioned conventional problems, and its purpose is to provide an improved and improved method for easily and accurately creating sewing data for sewing parts, etc., or for sewing the edges of parts. An object of the present invention is to provide a sewing data creation device for an automatic sewing machine.
