Abstract
A labelling device, particularly for applying a label to cigarette packets, and in which a shaft having at one end a label retaining member is mounted in a rotatable and axially slidable manner through a casing, which is supported by a support member so as to be oscillable relative thereto through an angle about an axis at right angles to said shaft; said support member being adjustable in position, and said casing enclosing first transmission means cyclically displacing said shaft axially relative to said casing to bring said label retaining member into a label application position, and second transmission means which are adjustable to a position in which they connect said casing and said shaft to one another so as to transform the oscillations of the casing into rotations of the shaft about its axis and relative to the casing.
Claims3
A labelling device, particularly for applying a label to packets, in particular cigarette packets of the hinged lid type, arranged flat on a support plane and advanced transversely therealong in a step-by-step manner;
- the labelling device comprising a feeding device for feeding in succession individual labels to a take-up position;
- stop means for stopping in succession each said packet on said support plane in an application position at which the respective label is applied;
- a support member the position of which is adjustable relative to said support plane in two directions parallel thereto and at right angles to one another, one of said two directions being parallel to the direction of advancement of said packets;
- a casing connected to said support member so as to be rotatable relative thereto about an axis parallel to said support plane and at right angles to said advancement direction;
- first actuating means operable cyclically to oscillate said casing at a predetermined frequency about said axis through an angle;
- a main shaft extending through said casing in a rotatable and axially slidable manner and arranged at right angles to said axis;
- a label retaining means connected to said main shaft and oscillable therewith and said casing about said axis through said angle between said take-up position and a ready-to-work position arranged above said application position;
- second actuating means operable cyclically at the same frequency as said first actuating means to displace axially said label retaining means between said ready-to-work position and said application position;
- and transmission means adjustable between a coupled position and a decoupled position to transform, when arranged in said coupled position, the oscillation of said casing through said angle into a rotation of about 90.degree. of said label retaining means about the axis of said main shaft.
