Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sewing data creation device for an automatic sewing machine that creates sewing data for controlling the automatic sewing machine.

[Conventional technology]

As is well known, in industrial sewing machines, sewing data pre-programmed in a memory device is recorded and held, and based on this sewing data, the cloth or needle is automatically controlled according to a predetermined sewing pattern to create a desired sewing pattern. Equipped with an automatic sewing mechanism that automatically performs sewing processing. This automatic sewing data is written to a storage medium in one storage device, and by exchanging this storage medium, it is possible to arbitrarily select and sew a different rope pattern, which saves labor on the sewing machine. This greatly contributes to improving sewing speed. A semiconductor memory such as an EPROM, 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. In normal cases, sewing data consists of the relative displacement of the needle and cloth for each stitch of the sewing machine that forms the sewing pattern, the sewing speed, and other movement control commands, and the control information for one sewing pattern is It is formed as a set of control commands.

Therefore, in order to automatically sew a desired sewing pattern with this type of automatic sewing machine, the sewing data corresponding to the sewing pattern is input into the sewing data creation device, and after being edited with correction 2, it is written to a designated storage medium. Sewing data creation work is required.

[Problem that the invention seeks to solve]

However, in the case of complex sewing patterns, the amount of data becomes extremely large, so this data must be corrected.

Editing may require a very large memory area, but since the sewing data creation device has a memory area determined to accommodate general sewing patterns, this memory area may not be sufficient. This method has the disadvantage that it cannot process complicated sewing patterns that require a large amount of data. Although this drawback can be eliminated by making the entire memory area open, it is not preferable to make the entire memory area open for infrequent special uses because it lowers economic efficiency.

The present invention was made to solve this problem, and an object of the present invention is to provide a device that can create complicated sewing data without using up the entire storage area.

[Means to solve all problems]

In order to solve these drawbacks, the present invention provides a communication means to utilize the storage area of the external device.

[For production]

Memory area expands.

〔Example〕

The figure shows one embodiment of this invention. In the figure, 1 is a control device, 2 is a storage display unit, and 3 is a digitizer. The control device 1 includes a microcomputer 11, a ROM 12 for system programs, a RAM 13 for relative value data and registration data, and a RAM 14 for a stack. , is a communication means for exchanging data with an external device, for example, 1tS23
It is composed of a communication control device 15 consisting of 2C. The storage display unit 2 includes a display panel 21 and an EPROM writer 22.
It consists of The digitizer 3 is divided into a pattern input section that can input a desired sewing pattern as an image, and an operation key input section that has operation keys for modifying and editing the input data.

In the device configured as described above, when a stylus pen (not shown) contacts the pattern input section of the digitizer 3, a signal corresponding to the coordinates of the pattern input section is controlled by the microcomputer 11 and stored in the RAM 13. . Then, as the stylus pen is moved according to the sewing pattern, the sewing pattern for sewing is displayed on the display panel 21. When sewing pattern data is inputted sequentially in this manner, the storage area of the RAM 13 becomes insufficient for complicated sewing patterns. At this time, the microcomputer 11 determines that the storage area is insufficient and displays it on the display panel 21. When the operator recognizes this and operates the operation key of the digitizer 3, the subsequent data is transferred to the external device via the communication control device 15. It is sent to the device and stored there. At this time, if the external device is a personal computer, the sewing pattern can also be displayed there.

In this way, data exceeding the internal storage capacity r is stored in the storage area of the external device, so the operator can work without considering the remaining internal capacity. and,
When the data input is completed, operate the operation key input section of the digitizer 3 to perform data correction 2 editing, and finally the edited data '! i: Write to the EPROM, which is a storage element, via the EPROM writer 22.

Note that if the final data content is too large to be stored in the EPROM, it may be possible to store it in an external device.

〔Effect of the invention〕

As explained above, since the present invention is provided with a communication means for exchanging sewing data with an external device, even if the internal storage area is insufficient, the data stored in the external device can still be stored.
．． Since it is possible to use Hieriya, it is possible to create data for complicated sewing patterns economically and with ease.
