    • The invention relates to a coupling system, in particular for mechanically coupling a positioning mechanism to a gripper rail, comprising a coupling device (1), in particular on a positioning mechanism, a counter coupling device (2), in particular on a gripper rail, wherein the coupling device (1) and the counter coupling device (2) can be selectively coupled together or uncoupled, and a locking device (8-33), which locks the coupling device (1) to the counter coupling device (2) in a locking state and unlocks the coupling device (1) and the counter coupling device (2) in an unlocking state. According to the invention, the locking device (8-33) unlocks and locks solely on the basis of the motion of the coupling device (1) and of the counter coupling device (2) without an external drive.
    • 本发明涉及一种联接系统,特别是用于将定位机构机械地联接到夹持器轨道,该联接系统包括联接装置(1),特别是在定位机构上,反向联接装置(2),特别是在夹持轨道 ,其中所述联接装置(1)和所述计数器联接装置(2)可以选择性地联接在一起或不联接;以及锁定装置(8-33),其将所述联接装置(1)锁定到所述计数器联接装置(2) 处于锁定状态,并且将解耦装置(1)和计数器耦合装置(2)解锁。 根据本发明,锁定装置(8-33)仅在没有外部驱动器的情况下基于联接装置(1)和计数器联接装置(2)的运动而解锁和锁定。
