Electronically controlled pattern sewing machine for automatically detecting and programming coordinate of sewing object and method for controlling the same

Abstract

An electronically controlled pattern sewing machine automatically detects and programs coordinates of a sewing line of a sewing object even if the coordinates of the sewing line are not manually set and programmed, thereby reducing costs and making skilled workers unnecessary. A jig disposed on the sewing machine to support a fabric thereagainst and having a pattern-shaped through hole formed thereon. A sensor coupled to one side of the sewing machine to sense coordinates of a periphery of the pattern-shaped through hole of the jig. A memory to store the coordinates sensed by the sensing part. A controller to automatically convert the coordinates stored in the storage into sewing coordinates. A setting part to set sewing functions on the sewing coordinates and a panel box to operate the sewing machine according to the sewing coordinates converted by the controller and the sewing functions set by the setting part.

Description

TECHNICAL FIELD[0001]The present invention relates to an electronically controlled pattern sewing machine and a method for controlling the same, and more particularly, to an electronically controlled pattern sewing machine that automatically detects and programs coordinates of a sewing line of a sewing object even if the coordinates of the sewing line are not manually set and programmed, thereby reducing costs and making skilled workers unnecessary.BACKGROUND OF THE INVENTION[0002]As well known, a sewing machine is a machine used to stitch fabric, leather, paper, vinyl, and other materials together with thread to bond the stitched materials to two layers or more, and an electronically controlled pattern sewing machine is a computer sewing machine that replaces hand-powered and foot-powered cranks used in the general sewing machines with a motor and a control technology of an electronic device to thus automatically perform a sewing operation for various patterns through electrical si...

AI Technical Summary

Benefits of technology

The present invention is for an electronically controlled pattern sewing machine and method for controlling it. The machine can accurately sew patterns without requiring CAD or program equipment. It can also sense the coordinates of a pattern and perform the sewing operation even if the jig is not installed correctly. The machine can automatically sense the pattern coordinates, convert them into suitable sewing coordinates, and program them. This allows for accurate sewing to the shape of the pattern, even if coordinates are not inputted one by one.

Problems solved by technology

At this time, if the jig is not disposed at an accurate position, the jig itself is made incorrectly, or the coordinates X and Y are erroneously inputted from equipment only for program (for example, CAD or punching device), the needle of the electronically controlled pattern sewing machine hits top of the jig, and otherwise, the fabric fixedly located in the jig becomes sewn wrongly.

Through the repetition of the above-mentioned processes over several times, normal sewing is achieved, which undesirably requires lots of time and steps.

In addition, a lot of time is unnecessarily consumed to repeatedly perform the tests for the accurate installation of the jig and the re-installation of the jig according to the tests, and accordingly, highly-skilled workers should be needed.

Of course, the coordinates of the sewing object can be directly inputted and stored one by one by means of the operation panel box, not by means of the CAD or the punching device as the program equipment only for pattern, but in this case, it is very hard to input one by one the coordinates of each sewing line through key buttons of the operation panel box.

Also, input time is very long.

Therefore, the coordinate input completion is not easy, and also, long time is needed to gain skill in the manipulation.
