Abstract
A driver for use in collecting and packaging machines has a base member securable on a transport system. A drive lever is arranged pivotably on the base member so as to pivot at least between a swung-out drive position and a folded safety position. A spring element acts on the drive lever. The spring element, in the drive position of the drive lever, secures by a spring force the drive lever in the drive position but releases the drive lever, when a first counterforce surpassing the spring force acts on the drive lever, for pivoting the drive lever from the drive position into the safety position.
Claims11
A driver for use in collecting and packaging machines, the driver comprising:
- a base member securable on a transport system;
- a drive lever including a drive edge arranged pivotably on the base member so as to pivot at least between a swung-out drive position and a folded safety position;
- a spring element acting on the drive lever;
- wherein the spring element, in the drive position of the drive lever, secures by a spring force the drive lever in the drive position but releases the drive lever, when a first counterforce surpassing the spring force acts on the drive lever, for pivoting the drive lever from the drive position into the safety position, wherein the drive lever is substantially triangular in an effective area projecting from the base member, the drive lever comprising the drive edge extending essentially perpendicularly to a transport direction in the drive position, a rear edge extending slantedly relative to the transport direction in the drive position, and a base edge that, in the drive position, rests against the base member, wherein, in the safety position of the drive lever a wedge-shaped engagement space is formed between the rear edge and the transport direction adapted for engaging an erecting element for erecting the drive lever from the safety position into the drive position.
