摘要： A digitally indexed reciprocating linear actuator includes a frame and a servomotor mounted to the frame. A crank is gear-coupled with integer gear ratio to the servomotor for unidirectional rotation. An actuator slide with a non-home index point is slideably-mounted to the frame for linear motion. A connecting rod couples the crank to the actuator slide. The actuator also includes means, including a sensor, for detecting the index point at two angular positions of the crank. A wrapping machine for wrapping a plurality of articles has repeated cycles of article-handling operations and a plurality of carriages, each carriage capable of moving at least one article for wrapping. The wrapping machine includes at least one digitally indexed reciprocating linear actuator having a crank, and an actuator slide with a non-home index point. The wrapping machine records first and second servomotor angular positions on detecting the index point at first and second angular positions of the crank. The wrapping machine identifies home position as an angular position midway between the first and second positions.

摘要翻译： 数字分度的往复式线性致动器包括安装到框架的框架和伺服电机。 曲轴与整体齿轮比与伺服电机齿轮耦合，用于单向旋转。 具有非家庭索引点的致动器滑块可滑动地安装到框架上用于线性运动。 连杆将曲柄连接到执行器滑块。 致动器还包括用于检测曲柄的两个角位置处的指标点的装置，包括传感器。 用于包装多个物品的包装机具有物品处理操作和多个托架的重复循环，每个托架能够移动至少一个物品以进行包装。 包装机包括至少一个具有曲柄的数字索引的往复线性致动器，以及具有非家庭索引点的致动器滑块。 包裹机器在曲柄的第一和第二角位置检测到索引点时记录第一和第二伺服马达角度位置。 包装机将起始位置识别为在第一和第二位置之间的中间角度位置。
