Textile sewing machine, perching device and cloth sewing method

Abstract

The invention discloses a textile sewing machine, a perching device and a cloth sewing method. The textile sewing machine comprises a lower pressing block and an upper pressing block, wherein the position of the lower pressing block is fixed, the top face of the lower pressing block is non-planar, a first passage is formed in at least a protruding area of the top face, the upper pressing block canreciprocate relative to the lower pressing block, the bottom face of the upper pressing block can fit the top face of the lower pressing block, a second passage is formed in at least a protruding area of the bottom face, the projections of the second passage and first passage on a same projective plane are located on a same straight line, and when the lower pressing block fits the upper pressingblock, the first passage is communicated with the second passage. The cooperation of the two specially-made pressing blocks is adopted for making head and tail areas of two coils of coil stocks foldedand is combined with the passages allowing a needle to pass through, thereby being conductive to the continuous inspection of the cloth coil stocks after the two coils of coil stocks are sewn together through the needle, so that the conventional thinking mode of performing feeding inspection on another coil stock after one coil stock is inspected in an existing test is changed, and the improvement of the operation efficiency is facilitated.

Description

technical field [0001] The invention relates to the field of automatic processing equipment, in particular to a textile seaming machine, a cloth inspection device and a cloth seaming method. Background technique [0002] In the production of textile printing and dyeing products, cloth surface defects are one of the important factors affecting the quality of cloth, and cloth surface defect inspection is an important link in cloth production. [0003] So far, the inspection of cloth defects is generally done by human eyes, and the specific process is as follows: Under certain lighting conditions, the cloth rolls are unrolled manually or through a cloth inspection device, and the inspection table is scanned with the naked eye. Whether there is light leakage in the cloth, if there is, stop the rotation of the roll material, mark and record the defect position, and then continue to inspect. After the inspection of a roll of cloth is completed, the grade of the cloth can be judged...

Problems solved by technology

[0004] However, the degree of automation of this method is low, and the speed of manual inspection is generally 15-20 m / min, which is inefficient and labor-intensive; at the same time, manual inspection is greatly affected by human factors, and the quality of inspection is not guaranteed.

[0005] Although there are also cloth inspection devices that use automated equipment for cloth defect detection, for example, combined with visual recognition equipment for defect point identification, it mainly collects images of the cloth surface to analyze whether there are defect points in the image. This cloth inspection device solves the problem of There are many problems in manual inspection, but when inspecting, after the inspection of the previous roll of fabric is completed, it is necessary to manually put another roll of fabric into the machine, and rewind the cloth head area of ​​the fabric to the rotating shaft, and then In order to continue the follow-up inspection operation, this method of re-feeding greatly caused a loss of time, and it was impossible to realize the sewing of two rolls of fabrics, making it difficult to carry out continuous production, which reduced work efficiency and increased production costs.
