自动穿鞋带机的柔性精准高效鞋面夹具与上下料机构设计

Flexible Accurate Efficient Vamp Fixture and Feeding Blanking Mechanism Design of Auto-Lacing Machine

针对目前传统手工穿鞋带时鞋面夹具定位精度低、适应性差、拆装效率低下等缺点,设计了基于自动穿鞋带机的新式鞋面夹具,采用梳齿结构,实现了贴近鞋孔附近区域鞋面的有效支撑;提出可动滑块式及可拆卸式2种柔性化夹具方案,实现了鞋孔支撑结构间距可变。针对可行性更高的可拆卸式方案,设计了鞋孔支撑结构与配套的定位机构,实现了鞋孔快速、精准定位;设计了基于双边对称同时夹紧方式的梳齿板式夹紧机构,实现了鞋面高效、平整的夹紧;设计了鞋面单机、流水线高效上下料机构,实现一人分管多台机器时的连续鞋面装夹。结果表明可拆卸式夹具不仅具有精度高、适应性广等特点,且可有效提高鞋面装夹、穿系效率。本夹具能改善鞋面的鞋带穿系现状,提高制鞋业自动化程度。

Aiming at current traditional manual shoe lacing fixture disadvantages such as low positioning accuracy,poor adaptability and low efficiency,this paper designed a new vamp fixture which was based on auto-lacing machine. This paper adopted comb dent structure which effectively supported vamp area near the hole. This paper put forward the movable gliding block scheme and the removable scheme,and realized the eyelet support structure space variable. With regard to the removable scheme which was more feasible,this paper designed the eyelet support structure and matching fixing position mechanism,realizing the eyelet rapidly and accurately positioned. This paper designed comb plate shape of clamping mechanism which was based on clamping way of bilateral symmetry at the same time,realizing the efficiently and smoothly clamping of vamp. Finally,this paper designed the efficient vamp feeding and blanking mechanism of single machine and assembly line which realized one person in charge of continuous vamp clamping of several machines.The result shows that the removable scheme not only has the characteristics of high precision,wide adaptability,but also can improves the efficiency of vamp clamping and wearing. This fixture can improve present situation shoe lacing of vamp,and improve the shoe industry automation.
