Description

[0001] Automatic sewing equipment with variable sewing position [0002]

The present invention relates to an automatic sewing machine, and more particularly, to an automatic sewing machine capable of freely moving a sewing part in accordance with the shape of a workpiece so that the position of the sewing part can be changed so that curved sewing and arc- To an automatic sewing machine.

In general, a sewing machine (sewing machine) sewing a fabric or a garment according to a sewing operation performed by an upper thread and a lower thread causes the upper thread to move from the upper portion of the threaded object to the lower thread portion So that the stitches are stitched together while being crossed with the lower thread supplied from the stitching machine.

Such a conventional sewing machine is divided into a manual sewing machine and an electric sewing machine. In the case of manual sewing, since the sewing machine must directly step on the foot for the up and down movement of the sewing needle, the ankle and knee of the sewing machine are painful and tired .

In the electric type, a motorized sewing machine is used in which a sewing needle is repeatedly lifted and lowered by a power transmission means such as a motor to a side of a workpiece, and a workpiece such as a fabric or clothes to be sewn by the sewing thread is placed on the lower side of the presser foot The sewing needle is repeatedly raised and lowered by the driving means to provide the upper thread to the lower thread side while the upper thread provided to the lower thread side is crossed with the lower thread to perform the sewing work on the threaded object, So that the problem of sewing on foot is solved.

Further, in the conventional art, since the sewing work is continuously performed while the sewing thread is continuously pushed so as to pass through the sewing needle, that is, the sewing needle repeatedly raised and lowered by the power transmission means, There is a problem that it becomes difficult for the user.

On the other hand, in the case of an automatic sewing machine for sewing a fabric, the supplied fabric is allowed to pass through the sewing portion after the sewing operation, so that the sewing machine can sew the long fabric without pushing the sewing material continuously. In order to allow the fabric to pass through, a separate device for pulling the fabric on the other side of the sewing section is provided.

However, in the case of an automatic sewing machine which conventionally performs a sewing operation automatically, it is possible to perform sewing in a straight line, but a sewing operation in a straight direction, a curved direction or an oblique direction of a braided article such as clothes can not proceed at all This is because only the sewing needle is repeatedly raised and lowered in the vertical direction by the transmission means in a state where the position of the sewing section is always fixed.

Accordingly, in the conventional automatic sewing machine, although it is possible to perform a sewing work for a straight line, that is, a sewing operation for connecting a fabric and another fabric in a straight line, it is possible to sew in a variety of directions such as a curved or oblique direction In order to perform the sewing work, the sewing thread is required to be sewn only by the sewing thread, because the sewing thread is directly sewn by changing the direction of the cloth while rotating the clothes such as clothing. There is a problem that a cost burden is caused.

The conventional sewing machine automatic sewing machine, which is a public sewing machine 20-1994-0004064, has been developed. When the presser switch is pressed, the motor is operated and the solenoid valve is operated to operate the presser foot driving cylinder, A non-step automatic sewing machine, comprising: a first beam sensor for sensing sewing to be automatically driven; a delay timer for driving the motor after a predetermined time has elapsed after detecting the sewing material; And a second beam sensor for performing a sewing work even if a worker (sewing thread) does not use the foot at all.

However, as mentioned above, in the conventional art, as described above, in the case of the various kinds of the sewing thread, the sewing thread is necessarily required because the sewing thread performs the sewing work while directly turning the threading direction.
