Abstract
A labelling machine for labelling containers may include at least a container feed means, a labelling region, a container removal means, and at least one labelling unit for processing labels from the roll. The labelling unit may comprise at least one label roll, a label feeder, a cutting device, a gripper cylinder, and at least one gluing mechanism. The cutting device may be constituted by a rotating vacuum roller and a rotating parting element which, on its circumference, has at least one parting tool, for example, a cutting blade, and the cutting device may be held by a common support device having, at least, a base part and a cover part. The support device has the same mean coefficient of thermal expansion as the rotating vacuum roller and the rotating parting element.
Claims23
Labelling machine for labelling containers, comprising:
- a container feed device;
- a labelling region;
- a container removal device;
- and
- at least one labelling unit for processing labels from a roll, the labelling unit including
- at least one label roll,
- a label feeder,
- a gripper cylinder,
- at least one gluing mechanism,
- a cutting device, the cutting device comprising a rotating vacuum roller and a rotating parting element which, on its circumference, has at least one parting tool, and
- a common support device holding the cutting device, the common support device having a base part and a cover part, the rotating vacuum roller and the rotating parting element being rotatably mounted to the base part in a desired spaced apart relationship relative to one another in a non-thermally-expanded condition,
- wherein the support device comprises a plurality of different materials, the support device having a mean coefficient of thermal expansion corresponding substantially to the mean coefficient of thermal expansion of the rotating vacuum roller and the rotating parting element such that, when in a thermally-expanded condition, expansion of the support device compensates for expansion of the rotating vacuum roller and the rotating parting element to maintain the rotating vacuum roller and the rotating parting element substantially in said desired spaced apart relationship.
Labelling machine for labelling containers, comprising:
- a container feed device;
- a labelling region;
- a container removal device;
- and
- at least one labelling unit for processing labels from a roll, the labelling unit including
- at least one label roll,
- a label feeder,
- a gripper cylinder,
- at least one gluing mechanism,
- a cutting device, the cutting device comprising a rotating vacuum roller and a rotating parting element which, on its circumference, has at least one parting tool, and
- a common support device holding the cutting device, the common support device having a base part and a cover part, the rotating vacuum roller and the rotating parting element being rotatably mounted to the base part in a desired spaced apart relationship relative to one another in a non-thermally-expanded condition,
- wherein the base part is constructed of a plurality of materials, each of said materials have a differing coefficient of thermal expansion, said base part having a mean coefficient of thermal expansion, the mean coefficient of thermal expansion of the base part being approximately equal to the mean coefficient of thermal expansion of the cover part, the vacuum roller, and the rotating parting element such that during high speed operation of the machine, thermal expansion of the base part and the cover part of the support device compensates for expansion of the rotating vacuum roller and the rotating parting element to maintain the rotating vacuum roller and the rotating parting element substantially in said desired spaced apart relationship.
