Abstract
A quick-change coupling is described for a container treatment machine, in particular a capping machine, with an outer member and an inner member engaging therewith in a positive-fit manner, between which members torques in a working direction of rotation and axial forces can be transmitted. Due to the fact that the outer member and the inner member are connectable to each other by pushing one into the other and twisting, a simple connection/separation of the quick-change coupling is possible without tools, as well as reliable and play-free transmission of unidirectional torques and contact pressure forces.
Claims19
A quick-change coupling for a container treatment machine, comprising:
- an outer member and an inner member engaging therewith in a positive locking manner between which the outer member and the inner member torque in a working direction of rotation and axial forces can be transmitted,
- wherein said outer member and said inner member are connected to each other by pushing one of the outer member and the inner member into the other of the outer member and the inner member and subsequently twisting,
- wherein said outer member comprises locking pins preloaded resiliently inwardly, and
- wherein said inner member comprises first guide bevels for said locking pins for forcing said locking pins outwardly when one of the outer member and the inner member is pushed into the other of the outer member and the inner member, and engagement recesses in which said locking pins can engage in a rotationally fixed and axially fixed manner during the subsequent twisting in the working direction of rotation,
- wherein, directly at the end of the twisting motion, the locking pins engage inwardly in the radial direction in the engagement recesses due to spring tension,
- wherein second guide bevels are formed on said engagement recesses for said locking pins for forcing said locking pins outwardly during the twisting in a direction opposite to said working direction of rotation and to guide them out from said engagement recesses.
