Description

Automatic cloth laying device with self-adaptive tension control function and deviation correcting method thereof Technical Field The invention relates to the field of cloth processing, in particular to an automatic cloth laying device with self-adaptive tension control and a deviation correcting method thereof. Background In the cloth processing industry, automatic cloth laying is the basis of subsequent cutting, sewing and other procedures, and the laying precision and stability of the automatic cloth laying directly influence the quality of a final product. At present, the technical scheme of combining deflection action and tension adjustment action of a deflection correcting roller is designed in the industry, so that the problem of mutual interference of deflection correction and tension adjustment is relieved to a certain extent, but the scheme can only realize overall adjustment of overall tension of cloth, cannot accurately compensate for single-side tension unbalance in the width direction caused by deflection, cannot strengthen deflection correcting effect through auxiliary acting force in the width direction, still has response dislocation of deflection correcting action and tension compensation, and does not radically break the circulation of secondary deflection caused by deflection correction and tension fluctuation. The existing deviation correcting device can not solve the problems of middle folds and edge wavy edges caused by uneven internal tension of the width aiming at wide cloth, and has extremely poor suitability for ultrathin high-elasticity and other easily deformable fabrics. The existing supplemental deviation rectifying scheme aiming at the deviation of the cloth edge mostly adopts an edge baffle wheel, a fixed limit roller and a clamping roller type deviation rectifying structure, and the scheme can only realize passive limit of the cloth edge, can not provide active centripetal rectifying force, has extremely low deviation rectifying efficiency and is extremely easy to generate deviation rectifying failure under a high-speed working condition. And the hard contact type limiting structure is extremely easy to cause yarn hooking, fuzzing and stretching deformation of the cloth edge, and especially has serious damage to light and thin fabric with high added value. In addition, the existing edge deviation rectifying structure is completely independent of the main deviation rectifying and tension adjusting system, cannot form cooperative linkage with the action of the main deviation rectifying roller, and even aggravates unilateral tension unbalance due to forced limit of the edge, so that tension stability and laying accuracy of cloth are further worsened. In order to solve the pain point, a plurality of groups of distributed tension sensors, independent edge actuating mechanisms and complex multi-axis cooperative control logic are additionally arranged in the industry to try to realize the cooperative control of accurate adjustment of the width tension and edge deviation correction. But the scheme not only greatly improves the manufacturing cost and the daily maintenance difficulty of equipment, but also is extremely easy to generate the problems of unsynchronized multi-sensor signals and uncoordinated actions of a multi-actuator, the system failure rate is obviously improved, and the core requirements of industrial continuous production on low cost, high reliability and full-field Jing Gao suitability cannot be met, so that an automatic cloth laying device with self-adaptive tension control needs to be designed.
