A control method for fabric horizontal alignment and anti-error reporting

Abstract

The invention provides a horizontal fabric alignment anti-error control method and belongs to the technical field of fabric alignment control. The problem that an error is easily caused during alignment of the conventional fabric if wool exists at the front end is solved. The control method comprises the following steps: S1, horizontally arranging the fabric on a sewing platform, and driving a fabric pressure plate to downwards press the fabric by a pressing mechanism; S2, driving the fabric pressure plate and the fabric to move towards a horizontal direction of a target position by a horizontal moving mechanism until the fabric is detected by a horizontal position sensor, and stopping working; S3, driving the fabric pressure plate and the fabric to move a vertical direction of the targetposition by a set distance A by a vertical moving mechanism, and stopping working; S4, judging whether the fabric is detected by the horizontal position sensor, if so, repeatedly executing the steps S3 and S4 until the fabric is detected by a vertical position sensor; if not, repeatedly executing the steps S2, S3 and S4 until the fabric is detected by the vertical position sensor. The control method has the advantage of being accurate in alignment.

Description

technical field [0001] The invention belongs to the technical field of fabric alignment control, and relates to a control method for fabric horizontal alignment and error prevention. Background technique [0002] During the sewing process, the fabric will be moved and aligned to the specified position, especially when the current process is completed and moved to the next process, it is necessary to move the fabric to the specified position to start the processing of the next process. [0003] The existing cloth movement is generally by pressing the cloth on the sewing platform, and then moving the cloth pressing plate horizontally and vertically through the horizontal and vertical moving motors, the horizontal position sensor and the vertical position The sensor is used to judge whether the alignment fabric has moved to the specified position. For example, the published publication number CN104178941A, titled as a Chinese patent on a fully automatic feeding and retrieving ...

AI Technical Summary

Problems solved by technology

However, there are still some problems: the above-mentioned technical solution has high alignment accuracy when the front end and one side of the cloth are flat cut surfaces, but when there is a certain length of hair at the front end of the cloth, it is often detected when performing horizontal alignment. Inaccuracy leads to deviations in the alignment, and there is an error reporting phenomenon. In practice, it is more common to have a certain length of cloth wool at the front end of the cloth.
