Technical Field:

The present invention relates to a 90-degree automatic fabric thickness reading system that is used in the kangaroo pocket sewing process integrated with sewing machines used in the manufacturing of textile products, and thanks to its thickness -reading photocell, it enables smooth sewing of a high number of kangaroo pockets on elastic fabrics with the least number of workers.

State of the Art and Objectives of the Invention:

In the classical sewing machine systems used today, the sewing of kangaroo pockets on elastic fabrics is performed manually by each worker. Therefore, among the two elastic fabrics put on top of each other, the one on top that is to be sewed as the pocket cannot be sewed on the one at the bottom without problem, overruns on seam lines are experienced, and it is not possible to produce the desired number of pockets since all relevant operations are performed manually by workers.

On the other side, with the invention, it is possible to smoothly sew a high number of kangaroo pockets on elastic fabrics with the least number of workers, thanks to its thickness-reading photocell. This system correctly detects the thickness of not the fabric at the bottom where the pocket is sewed, but of the fabric on top that is sewed as the pocket, and it determines exactly the starting and ending points of the seam based on the thickness of the fabric accordingly. Thus, overrun is not experienced on any seam, and the operations of drawing the fabric size, adjusting the pocket part, and completing the sewing can be easily performed by a single worker in a fast and error-free manner. In addition, in the systems in the state of the art, a master worker can sew maximum 250-300 pockets on average in one working day. Thanks to this invention, even a novice worker can sew 3000-3500 pockets on average in one working day.

Therefore, the invention has significant superiorities compared to the systems in the state of the art in terms of labor cost, raw material cost, time use, production amount, and perfectness of produced products.

Description of the Invention:

The present invention relates to a 90-degree automatic fabric thickness reading system (15) that is used in the kangaroo pocket sewing process integrated with sewing machines used in the manufacturing of textile products, and thanks to its thickness - reading photocell (3), it enables smooth sewing of a high number of kangaroo pockets on elastic fabrics with the least number of workers.

With the invention, it is possible to smoothly sew a high number of kangaroo pockets on elastic fabrics with the least number of workers, thanks to its thickness -reading photocell (3). This system correctly detects the thickness of not the fabric at the bottom where the pocket is sewed, but of the fabric on top, and it determines exactly the starting and ending points of the seam based on the thickness of the fabric accordingly. Thus, overrun is not experienced on any seam, and the operations of drawing the fabric size, adjusting the pocket part, and completing the sewing can be easily performed by a single worker in a fast and error-free manner.

For the assembly of the invention, the servo motor (7) that drives the main crawl (14) is fixed on the main body (10) with the help of two rings (6) that are integrated with the main body (10) with screws and nuts. The drive wheel (12) fixed on the lower end part of the servo motor (7) turns the main crawl (14) with the power supplied by the servo motor (7). The main crawl gear body (2) is fixed on the gap on the other end of the main body (10). The main crawl gear bearing (9) is placed on the main crawl gear body (2). The main crawl gear (1) is placed on the outmost part of the main crawl gear bearing

(9). The main crawl (14) reaching from the main crawl gear (1) on the lower part of the servo motor (7) wraps the main crawl gear (1) and provides it with the power to turn. The thickness-reading photocell (3) is fixed to the main crawl gear (1) with the photocell fastening sheet (8) attached by screws. Thanks to the ability of the thicknessreading photocell (3), which moves 90 degrees with the rotation power of the main crawl (14), to read the thickness of the fabric on top that is to be sewed as the pocket, the sewing machine needle that moves in the center gap of the main crawl gear body (2) completes the kangaroo pocket sewing in a fast and error-free manner.

Thanks to three main crawl bearings (13) fixed on the central end part of the main body

(10) with screws and nuts, it is ensured that the 90-degree moving thickness-reading photocell (3) easily moves without touching the main crawl (14). The connector (4) fixed with screws to the edge part of the main body (10) is connected with the body connecting plate (5) on the top with the help of screws and two distance pieces (11). The body connecting plate (5) is the part that connects the sewing machine body with the system.

Industrial Applicability of the Invention:

The invention can be manufactured under similar conditions to the existing products in terms of production process, production period, and production costs, and is totally industrial applicable.
