Full-automatic material taking and material feeding sewing machine

Abstract

The invention relates to a full-automatic material taking and material feeding sewing machine. The full-automatic material taking and material feeding sewing machine comprises a fabric taking device, a fabric position correction system, an air pump system and a sewing material pressing and feeding device, wherein a horizontal guide rail is arranged in the X direction above a machine frame; the entire fabric taking device can conduct movement in X direction along the horizontal guide rail and can further conduct movement in Z direction on the horizontal guide rail; a linear module in a Y direction is arranged at the lower part of the fabric taking device; a rotating and regulating mechanism is arranged at the lower part of the linear module in the Y direction; a sucking disc fixing plate is arranged at the lower part of the rotating and regulating mechanism; the fabric position correction system comprises a fabric position sensing device; the fabric position sensing device comprises at least three sensors and a driving system that monitors the position of the fabric and transmits the signals of the fabric position deviation to the fabric taking device; the driving system corrects the placing position of the fabric through adjusting the global movement of the fabric taking device in the X direction, the Y-direction movement of the linear module in the Y direction and the rotating angles of the rotating and regulating mechanism.

Description

technical field [0001] The invention relates to a sewing machine, in particular to a fully automatic feeding and feeding sewing machine, which belongs to the technical field of sewing machines. Background technique [0002] Existing automatic door buttonhole machines generally have two types: the first type is that the operator puts the keyhole length or number of each garment directly under the presser foot of the buttonhole machine for automatic sewing, and one buttonhole is cut at the same time. The eye opening completes a keyhole action. Usually, a piece of clothing has multiple keyholes, then the operator puts the keyhole machine into the keyhole machine for multiple manual keyholes according to the distance of each keyhole. This kind of work requires more operators and The labor intensity is relatively high. The second type is that the operator sets up the whole garment or semi-finished product and puts it on the discharge board with suction, adjusts the fabric to a su...

Problems solved by technology

[0004] The technical problem to be solved in the present invention is: the existing sewing machine, especially the buttonhole machine, needs the operator to manually unload the material every other time or several times during sewing, and the labor intensity of the operator is still relatively large, and the position of the cloth is still high. Manually controlled by the operator, the accuracy is low, which will lead to inaccurate buttonhole positions of the fabric or the phenomenon that different buttonhole positions on a piece of fabric are not on the same straight line, which will affect the appearance of the keyhole stitches of the fabric
