Abstract
A packaging machine comprises a folding box transporting device and a closing device for alignment and insertion of the closing flaps of a folding box, wherein the closing device supports at least one closing tool which rotates, via a drive and a gearing, while maintaining its orientation. The gearing is a planetary gearing which ensures precise motion of the closing tools even at high packaging machine cycle frequencies. The planetary support can thereby be connected to an intermediate shaft surrounded by a coaxially disposed hollow drive shaft, wherein the hollow drive shaft is borne for rigid rotation along with the intermediate shaft but in an axially displaceable fashion to permit axial or vertical adjustment of the planetary gearing and therefore of the closing tools.
Claims5
A closing device for aligning and inserting closure flaps of a folding box disposed on a folding box transporting means in a packaging machine, the device comprising:
- a stationary frame,
- drive means mounted to said frame;
- a planetary gearing connected to said drive means;
- a closing tool mounted to said planetary gearing and communicating with the folding box to align and insert the closure flaps, wherein said closing tool rotates while maintaining its orientation relative to the folding box;
- and
- an intermediate shaft surrounded by a coaxially disposed hollow drive shaft, said hollow drive shaft borne on said frame for rotation along with said intermediate shaft and for axial displacement relative thereto, wherein said planetary support is borne on said intermediate shaft.
