Abstract
A labelling unit and a method for labelling containers is provided. Said method provides rapid and reliable switching movements with low noise development and low wear of the mechanical components in that suction bars for suctioning label areas at places where container gaps occur can be actively switched back to an inner position, in which they do not come into contact with a gluing unit, and in that the switching process is triggered with the aid of a stationary toggle lever.
Claims15
A labeling unit, comprising:
- a vacuum transfer cylinder with suction bars for suctioning labels;
- a gluing unit formed adjacent to said vacuum transfer cylinder for applying glue onto said labels;
- and
- a stationary switching unit having a movable operating cam for switching said suction bars to an inner position wherein said suction bars pass said gluing unit without contacting it,
- wherein said stationary switching unit comprises a toggle lever for actuating said movable operating cam and a switching drive for angling the toggle lever, wherein the toggle lever includes a pair of end-side mounting points and a pair of center mounting points, a plane of the pair of end-side mounting points being parallel to a plane of the pair of center mounting points.
A method for labeling containers, in which labels are transferred to a vacuum transfer cylinder, attached there by way of suction bars and by the suction bars brought into contact with a gluing unit, where suction bars selectively not being charged with labels are switched back to an inner position in such a manner that said suction bars pass said gluing unit without contacting it, wherein an actuating force for switching back said suction bars is transferred to said suction bars by way of a stationary mounted toggle lever that is angled by a switching drive, the toggle lever including a pair of end-side mounting points and a pair of center mounting points, a plane of the pair of end-side mounting points maintained parallel to a plane of the pair of center mounting points while the toggle lever is angled.
