Description

[Detailed explanation of the invention] (a) Industrial application field This invention uses an automatic NC sewing machine to hold the sewing material between a feed plate and a presser plate, and sew a pattern with a single needle while feeding it. This item relates to a sewing aid used when sewing items such as name pleats, etc.

(b) Conventional technology Conventionally, when sewing patterns or name plates, etc., it was necessary to grasp the workpiece and move it in accordance with the feed of the fabric feed plate, or to They were placed on a stationary stand approximately at the same height as the board, and none of them corresponded to the present invention.

(c) Problems to be solved by the invention When gripping the dough with one's hand, it is extremely difficult and troublesome to move the dough in accordance with the feed of the dough, and if care is not taken, the gap between the feed plate and the presser plate may fall. If the latter stationary table is used, the fabric held between the sewing machine may shift due to the frictional force between the stationary table and the stationary table when it moves, making it impossible to sew normally. It was often impossible to do so.
In particular, when sewing a name plate near the band insertion part of pants, for example, the thickness of the fabric is not constant due to the folded fabric or the band loop, so the clamping is insufficient, and the edge of the pants may be sewn. Because of the clamping, most of the trousers were far off the sewing table of the sewing machine, and the weight caused a lot of misalignment, resulting in many defective products even with the utmost care.

(d) Means for solving the problem In order to improve the above-mentioned drawbacks, the present invention has a flexible flat plate arranged vertically at approximately the same height and horizontally so as to be connected to the feed plate for sewing fabric. The present invention is characterized in that a support body is attached to the upper end of the elastic body and a support body for supporting the elastic body is attached to the lower end of the elastic body, so that the elastic body is configured to be tiltable with respect to a vertical line.

(E) Function The flat plate of the sewing aid of the NC-type automatic sewing machine of the present invention is connected to the feed plate of the sewing fabric of the sewing machine, for example, by adhesive tape, and the sewing part is connected between the feed plate and the presser plate. When the sewing machine is operated with the part other than the clamped part placed on the flat plate of the auxiliary tool of the present invention, the sewing part moves in a preset manner by the feed plate while being clamped between the feed plate and the presser plate. and sew. In this case, the flat plate connected to the feed plate is connected above the support via an elastic body so that it can freely tilt with respect to the vertical line, so the flat plate tilts and moves together with the feed plate. The difference in inclination between the flat plate and the feed plate is eliminated by the deformation of the elastic body and the twisting of the flat plate due to the flexibility of the flat plate, so that the flat plate moves smoothly with the feed plate, and the sewing material is also held in the pinched portion. The parts that are not in place also move together, eliminating resistance to the fabric clamping part, so you can easily sew without any slippage.

(F) Example The example shown in the drawings will be explained below.
Reference numeral 1 denotes a feed plate for the sewing fabric of the NC automatic sewing machine A, which holds the sewing fabric between it and the presser plate 2 above it, moves back and forth and left and right according to preset instructions, and feeds the sewing fabric above it. I use the single needle 3 to sew patterns and name plates.
4 is an elastic body made of a coil spring, and has a pipe 6 fixed to a support 5 at its lower end and a pipe 7 fixed to its upper end, and the pipe 7 is made of flexible rubber, synthetic resin, etc. A support rod 9 attached to the lower surface of the flat plate 8 is inserted and set with a set screw 10.

Although the pipe 6 is bent in consideration of the worker's footing, it can be stood upright or extended using the lower part of the sewing machine table as a support. As shown in Figure 3, it is also possible to use a plurality of rubber hoses 11 as elastic bodies,
Further, in the above embodiment, the flat plate and the feed plate are connected with an adhesive tape, but they can also be locked with a locking tool, and either method has the same effect.

(g) Effects of the invention As described above, according to the invention, the flexible flat plate connected to the feed plate is simply connected above the support via an elastic body so as to be tiltable with respect to the vertical line. Therefore, it moves together with the feed plate with almost no resistance, and both the clamping part and the non-clamping part move together, so there is almost no resistance to the fabric clamping part, and you can easily sew with your hands without causing any slippage. Moreover, it has a simple structure and can be manufactured at low cost.
