When inserting a stretched thin elastic into underwear such as pants, swimsuits, or sleeves of clothing, an elastic insertion ruler consisting of a folded part of the body fabric and a rubber insertion part that can be moved from side to side is installed before the needle drops. The ruler is used to pass the stretched rubber between the folded fabrics and guide it to the needle drop, but when inserting the fabric, if the fabric is relatively soft, friction with the ruler or friction with the rubber may occur. As a result, the folded portion of the folded fabric becomes misaligned, resulting in a situation as shown in FIG. 1, which tends to cause loose stitches and wrinkles.

In addition, rubber is usually sewn to the body fabric for a certain length at the beginning and end, and the middle part is loosely fitted to take advantage of the elasticity of the rubber. However, it required skill to accurately form the non-sewn parts.

This invention was made with the aim of solving this problem, and an embodiment thereof will be explained below with reference to the drawings. As shown in detail in FIG.
, one side of the plate 7 on which the cloth W is placed is turned upside down.
It is bent in a letter shape, and its end is bent further upwards to form a fabric folded part 8 along the plate with an appropriate gap (see Fig. 4), and a pipe 9 is provided on the mounting part. The pipe is connected to a compressed air source by a tube 10 that incorporates a flow rate adjustment valve, a switching valve, etc., and also directs air to the vicinity of the cloth inlet of the fabric folding part 8 below the fabric folding part, that is, the folding part 8. It has an opening configured to eject the liquid so as to have a component forward in the feeding direction and a component perpendicular to the feeding direction obliquely toward the fabric edge (folded part) of the fabric W folded at the part. The ruler main body 11 can be slid laterally guided by a guide screw 13 fixed to the mounting part 6 through a horizontal hole 12, and is normally slid to the right in the figure by a spring 14 connected to the mounting part 6. A support plate 17 is attached to a stopper 16 which is biased by the spring and fixed in the right position by being joined to a stopper 16 which is fixed to the mounting portion 6 with a set screw 15 so that the position can be adjusted. 14, a bell crank-shaped connecting plate 19, a chain 20, and an operating mechanism consisting of a footplate (not shown) connected to the lower end of the chain; It consists of a rubber inserting tube 21 that moves left and right within the folded part by the operation of the mechanism, and the rubber inserting tube moves the narrow rubber 22 sent under the presser foot to the needle drop position and the right side of the needle drop position (cloth It is designed so that it can be moved to the end side) and to the detached position. In addition, 23 in the figure is a guessing ruler. Further, in FIG. 2, 25 is a rubber feeding device equipped with a rubber feeding roller 26 whose feeding amount can be adjusted intermittently in conjunction with the main shaft, and 27.
Similarly, the cloth puller device is intermittent fed in conjunction with the main shaft, and the amount of feed for nipping and feeding the sewing product after the needle drop is adjustable.

When inserting the elastic, usually first raise presser foot 1,
The rubber 22 is sandwiched between the feed rollers 26 of the rubber feeding device 25, passed through the rubber inserting tube 21 of the rubber inserting ruler 3, placed under the presser foot in close proximity to the ruler 23, and then pinched by the cloth puller device 27. , held in an extended position. Next, the cloth W which is the product to be sewn
is inserted into the elastic ruler 3, and at this time, depending on the type of fabric, the air blown into the folded fabric part 8 is controlled as follows using an air volume adjustment valve or a switching valve.

すなわち、比較的柔かい布の場合は、適度の風

That is, in the case of relatively soft cloth, the air volume is controlled to an appropriate level and the air is blown out from the time the cloth is inserted until the cloth is set under the presser foot to align the edges of the cloth.

また布端がカールする布の場合は、布の挿入時

If the fabric has curled edges, a suitable amount of air is ejected from the time the fabric is inserted until the end of sewing to stretch and align the fabric edges.

The switching of the switching valve that controls the timing of air blowout can be performed electrically or mechanically by operating a knee switch, and can also be performed using a known fabric edge detection sensor.
This can also be done automatically by using a hand movement counter, rotation detector, judgment circuit, etc. Figure 5 shows a block circuit diagram of such an automatic control device. When the fabric edge detection sensor installed on the elastic ruler detects the insertion of fabric, a signal is sent to the judgment circuit and counter counting circuit. An actuation signal is output to the solenoid valve to blow out air, and the counter counting circuit counts the number of hand movements based on the hand movement signal from the rotation detector. When the count reaches a preset count, a signal is output from the counter counting circuit and enters the judgment circuit, and the judgment circuit outputs an operation stop signal. This stops the air from blowing out. In the above device, the counter counting circuit is deactivated,
It is also possible to continue blowing air until the cloth comes out of the rubber-filled ruler and a signal is generated in the cloth edge detection sensor, and an operation stop signal is input to the solenoid valve through the judgment circuit. In this case, the solenoid valve used is preferably a flip-flop type.

The cloth W whose edges have been aligned by the air jet is then inserted under the presser foot. After the treadle is depressed and the rubber insertion tube 21 is moved to the left to the position where the rubber 22 is to be sewn, the presser foot is lowered and the sewing machine is started. When the sewing machine is started and the rubber 22 is sewn onto the fabric by about 1 cm, return the treadle, return the rubber insertion tube to its original right position, and remove the rubber from the needle drop. When the sewing end of the cloth approaches, the elastic tube is moved to the left side again, about 1 cm of the elastic is sewn in, and at the same time as sewing is finished, the elastic tube is returned to its original position.

In the above-mentioned sewing machine, rubber sewing is performed by operating the treadle, but like the automatic air control device described above, sewing is automatically performed using a fabric edge detection sensor, needle movement counter, rotation detector, etc. You can also do that. In other words, after the fabric edge detection sensor detects the edge of the fabric, the elastic tube is moved to the left until a predetermined count is reached, and then returned to its original position, and when the predetermined count is reached, it is moved to the left again. Become.

As described above, according to the present invention, even an unskilled person can easily and accurately insert the elastic without causing any loose stitches or wrinkles at the beginning of sewing.
