为了降低人力成本和提高生产效率,设计了类似于机械手的多功能装箱机.一般移载机或机械手在逐个夹取堆叠中的物品时,通常采取以两个光电检测配合变频或伺服系统的方法来确定夹取点位,这只能满足对精度要求不是很高的情况.但对夹取点位的精确度有严格要求的场合,需要提出新的办法解决.为了解决这个问题,利用伺服系统精确度高的优点,通过PLC精确计算来确定夹取点位.多功能装箱机经过在生产中应用证明,该系统性能稳定,夹取精度高.%In order to reduce operation costs and raise production efficiency, this paper uses PLC and servo control for the manipulators of multi-functional packing machines. In practical packing processes,transplanting machines or robotic hands are widely used for clamping individual items from the stack for the items,in this process frequency modification control or servo control are generally a-dopted in determining the clamping positions on individual items via double-point photoelectric detection, when position accurary needs not to be high. However,for the precision positioning requirement,we need to consider new technique. More precisely,we will develop a precise control technique for clamping operation in multi-functional packing machines by exploiting high precision of servo systems and calculating accuracy of the PLCs. In our practical application of suggested multi-functional packing machines,the packing system presents its stable performance with high clamping precision in the operation.
