Sewing material alignment unit and method of automatic sewing device, and automatic sewing device

Abstract

The invention provides a sewing material aligning unit of an automatic sewing device. The sewing material aligning unit comprises a table plate for installing a sewing machine, material pressing driving sources, material pressing pieces driven by the material pressing driving sources to move up and down, a material transfer manipulator, and material transfer pieces driven by the material transfer manipulator to move and used for driving a sewing material to move. The material pressing pieces and the material transfer pieces are positioned at an upper side of the table plate. When the material transfer pieces drive one corner of the sewing material to move to a position under the material pressing pieces, the material pressing driving sources drive the material pressing pieces to move downwardly and press the corner of the sewing material, and then the material transfer pieces drive the sewing material to move and deflect around the material pressing pieces. Aligning precision and accuracy of edges of the sewing material can be effectively improved, and therefore sewing quality of the sewing material is ensured. The sewing material aligning unit is simple in structure and easy to control, and alignment of the sewing material is easy to implement.

Description

technical field [0001] The invention relates to a sewing material alignment unit of automatic sewing equipment. [0002] The invention further relates to a method for aligning sewing materials of automatic sewing equipment. [0003] The present invention also relates to an automatic sewing device comprising the above-mentioned sewing material alignment unit. Background technique [0004] At present, automatic sewing equipment usually includes a cloth placing table, a separation unit, a clamping unit, an alignment unit, a sewing unit and a receiving unit, wherein, the cloth placing table is used to place a stack of cut pieces; A stack of cutting pieces is separated layer by layer, and the sewing material is separated; the clamping unit is used to clamp the separated sewing material, and the sewing material is transferred to the designated position on the table; the alignment unit is used to place the sewing material on the table Align the edges of the sewing materials to av...

AI Technical Summary

Problems solved by technology

[0007] 1. In most cases, the edge of the sewing material is an irregular curve, or in other words, the edge of the sewing material close to the sewing unit is close to a straight line, so it is not easy to adjust the parallelism between the fabric and the X direction. In turn, the accuracy of the alignment adjustment in the first step is greatly reduced, thereby affecting the overall alignment accuracy of the sewing material, so that the automatic sewing quality cannot be effectively guaranteed

[0008] 2. The working platen used to drive the movement of the fabric is directly installed on the manipulator, and the working platen needs to be located directly above the platen used to place the fabric, so that the whole manipulator is assumed to be on the platen along its extension direction (that is, the Y direction). Therefore, it will interfere with the movement of other equipment (such as the pre-adjusting power mechanism) in the fully automatic industrial sewing machine; in particular, when the operation of placing the cloth on the cloth placing table is switched from the fully automatic placing mode In the manual placement mode, since the manipulator blocks part of the platen, it is not easy to manually place the fabric
