YB55透明纸小包机使用拉带小卷筒时,通过人工旋紧螺纹夹紧卷筒,而且更换拉带次数频繁,停机时间长.采用拉带大卷筒自动夹紧装置后,减轻了操作人员的劳动强度,拉带更换周期由原来的4.5 h增加到12 h,停机时间由原来的10 min左右缩短为3 min左右,提高了包装机的有效作业率. 相似文献

A hybrid (symbolic-numeric) system, referred to as OPTDEX, (OPTIMAL DESIGN EXPERT) for the optimal design or mechanical components and systems has been developed. The system is written in Golden Common LISP and IBM Professional (Ryan-McFarland) FORTRAN for execution on the IBM PC/AT microcomputer. Graphical output has been implemented using the Graphical Kernel System (GKS) standard. This microcomputer-based implementation makes the system particularly attractive as an easily accessible, low cost engineering analysis and design tool. Experience with the system indicates that the time required to achieve, at least, partially optimized engineering design solutions is similar to that which may be expected with standard, nonoptimization-based, microcomputer computation. Any added computational time may be justified and subsequently offset by increased long term design efficacy. 相似文献

YB55包装机透明纸自动拼接装置的研制 总被引:1,自引:1,他引:0
YB55型盒外透明纸包装机采用的手动式透明纸拼接装置,每次停机更换透明纸时,会造成上游主机停机约2 min,影响设备的有效作业率,且造成原材料浪费.为此,研制了一套透明纸自动拼接装置,实现了透明纸卷转换过程中的自动拼接.拼接形式仍采用烙铁热熔粘合方式,机械传动部分采用摆杆式结构,由3个气缸组件作为执行元件,分别完成粘合和切割动作.该装置结构简单,操作方便,经过实际应用表明,透明纸拼接过程由原来的80~120 s/次,减少到5~10 s/次,提高了设备运行效率,减少了因停机而造成的原材料消耗. 相似文献
