Description

Automatic sewing apparatus for spangle

The present invention relates to a sequin sewing device that can automatically sew sequins for decoration on fabrics or finished products, and more particularly, sequin supply device for automatically supplying sequins to the sewing machine to sew sequins on the fabric and the sewing machine and It is equipped with a driving device that controls the operation of the sequin supply device and a control device with a program for automatically controlling all the devices including the drive device so that all operations from the supply of sequins to sewing can be automatically performed. It relates to an automatic sequin sewing machine that anyone can use easily.

Sequins (spangles or sequins) are sparkling ornaments made of synthetic resin that are sewn to the garments to adorn the garments.

To make a sequin sewn costume, there is a method of making a sequin in a prefabricated sewn fabric or sewing a sequin to an already finished garment.

In most cases, the sequin embroidery machine (embroidery weaving machine) shown in Figure 1 is making a garment with sequins sewn on the fabric paper fabric, otherwise the user attaches sequins to the garment finished with hand-sewn for the decoration of the costume have.

However, if the sequins sewn on the finished fabric or fabric fall off or the sequins are sewn in the wrong place, the sequins should be sewn only to the wrong parts for repair. The sequins must be sewn by hand using a small sewing machine (sewing machine) or by hand sewing.

Sequin embroidery machine is a large-size device that has more than 20 sewing machines that continuously sew a large number of sequins on fabric paper according to a pre-designed design.It is difficult to use sequins for sewing only part of the fabric paper. There is no choice but to use a sewing machine.

As such, a sequin sewing machine with a slight deformation of the normal sewing machine and an additional device installed to sew only a portion of the fabric is shown in FIG. 2, and the sequin sewing machine attaches a sequin supply device to the general sewing machine and sew manually. Manual sewing machine to perform work. The sequin sewing operation using such a manual sequin sewing machine is first performed by the operator presses the hand switch to discharge one of the pre-cut sequins to the sewing machine, and then stitches the sewing needle by using a foot switch. However, in order to sew sequins on the fabric, not only the hand switch and the foot switch must be operated separately, but the operator must move the fabric frame to the exact stitching position every time the sewing needle is moved up and down. In general, to sew one sequin on the fabric, it is necessary to sew three to nine stitches depending on the type. However, it is difficult to obtain a good sewing state because the worker has to move the frame one by one at short intervals in which the sewing needle moves up and down. .

Therefore, such a manual sequin sewing machine is difficult to use unless the skilled person after many years of experience, even if the skilled worker does not have the problem that the sequins are not sew correctly on the fabric and the work speed falls.

In addition, since the conventional manual sequin sewing machine uses a gear and a ratchet wheel driven by a DC motor to supply the sequins as shown in FIG. 2, the power consumption is large, and if the type of the sequins is changed, the stitching interval is changed according to the changed sequins. It is cumbersome to replace each part (gear box, sequin feed gear, ratchet wheel, etc.) of the sewing machine and sequin feeder to match the separable spacing, feed distance, etc.

In addition, the conventional manual sequin sewing machine is a structure in which the worker moves the fabric manually after sewing the fabric to the frame to sewing work, so in the case of already finished clothes can not fit the finished clothing to the frame having a certain size Due to the problem, the conventional manual sequin sewing machine also has a disadvantage that can not sew sequins on the finished garment.

The main object of the present invention for solving the above problems, by adding a sequin supply device, a driving device and a control device to the sewing machine to automatically perform all the processes of sequin sewing sequins by a single operation even for beginners or beginners It is to provide an automatic sequin sewing machine that can be sewn to the exact point of the fabric or finished clothes.

11 is a diagram illustrating the operation control flow of the automatic sequin sewing apparatus according to an embodiment of the present invention. And, Figure 12 is a flow chart showing a process of sewing work using an automatic sequin sewing apparatus according to an embodiment of the present invention.

First, when the power of the servo motor 31 and the control device is applied (S1), the home position setting button 62 of the hand switch 60 is pressed to find the origin of the needle bar 11 and the XY feed support 13 (S2). ), Set and save the sequin type and lockstitch type input to the control device (S3), and place the fabric or cloth on the XY transfer support of the sewing machine (S4). Then, sequins are put into the sewing machine by the sequin closing button 61 (S5), and then the foot switch 70 is lightly pressed in one step (S6). The presser foot up / down solenoid 15 presses the presser foot 14. Press down to fix the fabric (S7).

After confirming that the fabric is fixed and the sequins are in the correct position, press the foot switch 70 in two steps (S8). The servo motor 31, the step motors 32 and 33, which are the main shaft motors, and the solenoid for the presser foot up / down ( 15 is driven and the needle bar 11, the XY transfer support 13 and the presser foot 14 are automatically transferred and sewing is performed. At this time, the first and the last of the sewing operation is always to press the Start / End button 63 so as to form the triangulation (A) shown in FIG.

In the above description, the continuous operation mechanism of the sequin sewing machine will be described in more detail. When the foot switch 70 is pressed in two stages (continuously held state) (S8), the needle bar 11 is lowered (S9) to enter the center of the sequins. The sewing needle passes through the groove and is sewn (S10), the needle bar is raised (S11), and at the same time the XY transfer support and the presser foot are moved to the next sewing position (S12), the needle bar is lowered and sewn (S13). . Repeat this process a few times, when one sequin sewing is completed in the form of triangular (A), biangular (B) and hacksaw (C), the sewing needle and presser foot are raised and a new sequin is introduced from the sequin supply device. The sewing process is performed. These sewing operations are made automatically continuously, when you want to finish the work, if you step down the foot switch (S15) all the sewing work is finished.

The mechanism in which the sequins are automatically inserted will be described in more detail above.

First, pressing the sequin input button 61 of the hand switch or pressing the foot switch 70 in two stages, the step motor 34 is rotated to operate the belt pulley 28 of the sequin supply device. When the rotary arm 23 connected to the same axis as the pulley rotates to the rear by the rotation, the sequin forward preventing ring 24 fixed to the rotary arm rises and the linear transfer arm 25 connected to the rotary arm also moves backward. The sequin feed ring 26 in front of the straight transfer arm is also pitched backward along the sequin feed rail 22 to be caught by the center groove of the new sequin. At this time, the sequin reversal preventing ring 27 supports the sequins so that the sequin set is not pushed backwards.

Then, when the belt-pulley 28 is rotated in the opposite direction, the sequin anti-lock ring 24 fixed to the rotary arm 23 is lowered and the sequin feed ring 26 is pitched by one pitch to the sewing machine. Transfer. At the moment when the transfer of the sequins is completed, the sequins forward preventing ring 24 descends completely to support the sequins so that the sequins are not dragged forward when the sequins are cut by the sewing needle or the sequin cutter.

As described in the above embodiments, the present invention has the following effects.

First, all the sewing work is automatically done only by the operation of a simple button and the foot switch, even beginners or unskilled workers can easily sequin sewn work, which can significantly reduce labor costs when used in the factory.

Secondly, because it does not use a rim, it can be used to repair not only the woven fabric but also the finished garment with a narrow sewing work range, so that anyone in the home can easily attach the sequins to the clothing arbitrarily.

Third, unlike the conventional manual type, since the transfer of the fabric is made automatically, it is possible to maintain the accurate stitching interval, the sewing state of the sequins is good, the working speed is faster, and the work efficiency is greatly improved.

Fourth, since the exact point to sew sequins can be known in advance using a laser pointer, even if a novice works, almost no defect occurs.

Fifth, each time the type of sequins and the type of stitches are changed, the user simply inputs the changed contents directly into the control unit without having to replace each component. Therefore, the user can attach any type of sequins by simply inputting specifications of various kinds of sequins in advance.
