摘要：

针对因面料柔软、透气导致面料堆垛难以自动分层抓取、移送的问题,探讨了利用非接触式吸附技术进行面料堆垛分层的可行性。考虑面料悬垂特性、堆垛内气体流动压力损失和层间静电力等因素,构建了伯努利非接触式堆垛分层吸附力理论模型。为验证该模型的有效性和非接触式吸附系统的可靠性,进行了吸附力测试以及面料堆垛分层吸附试验。结果表明,所构建的吸附力理论模型与通用模型的结果偏差为26.17%;模型计算所得吸附力变化趋势与试验结果一致,数值与试验结果相差9.4%;利用模型计算所得工艺参数对面料堆垛进行分层吸附的成功率可达93%,所构建的吸附工艺模型与系统的有效性和可靠性较高。

Abstract:

Objective In the process of garment production, fabrics need to go through the processes of cutting, sewing, and ironing, and the garment production heavily relies on the manual transfer of fabric cuts, which is time-consuming and labor-intensive. Due to the lightweight, softness, permeability and other characteristics of the fabrics, the automatic fabric stack separation becomes a recognized technical problem, which restricts the automatic transformation and upgrading of the material flow link in the garment production line.

Method Aimed at fabric stack separation, the permeability, drape deformation, and electrostatic properties of the fabrics in the stack were characterized using theories of porous media, elastic thin plate bending deformation, and Coulomb's law. Subsequently, a mathematical model for fabric stack separation was established. In ordert validate the reliability and effectiveness of this model, an experimental platform for fabric stack separation was constructed.

Results The experimental platform for fabrics stack separation was constructed by considering the Bernoulli suction cup suction force control system and the Bernoulli suction cup posture control system. This study analyzed the process of layered suction on the fabrics stack using Bernoulli suction cup and identified the main influencing factors, which include 1) atmospheric pressure loss caused by fabric permeability, 2) the change in spacing height h caused by fabric drape deformation, and 3) interlayer electrostatic forces for fabrics that are prone to static electricity, this is something that was not taken into account by the general model constructed by previous researchers. Based on these, a pressure field calculation model that is more in line with the non-contact suction of preamthable soft materials such as fabrics, as well as a suction force model were constructed. The ctrape deformation analysis models for grey fabric and denim under the non-contact suction based on the elastic thin plate theory were found to better express their respective ctrape deformation. Comparison between the measured and theoretical values of deflection suggested a 4.9% error, and the deviation between the suction theoretical model and the general model is 26.17%. The suction process parameters of Bernoulli suction cups mainly included inlet flow rate Q and spacing height h. When the spacing height h was kept constant, the suction force demonstrated an increase with the increase of inlet flow rate Q. On the other hand, when the intake flow rate Q remained constant, the suction force was increased with the increase of spacing height h. The success rate of stack separation using the suction model calculation results reach as high as 93%.

Conclusion The deviation between the suction theoretical model and the general model is 26.17%, which compensates for the deficiency of the general model's suction capacity and can provide more accurate theoretical guidance for the process parameters required for fabric stack separation. The proposed suction model can accurately predict the changes in suction force, and the calculated results of the model differ by 9.4% from the experimental results. The success rate of stack separation using the suction model calculation results can reach 93%, and the proposed suction model and system have high effectiveness and reliability.
