Abstract
A labeling unit for applying labels to containers includes a label removing device, a vacuum drum, and a gluing device. The vacuum drum receives labels at a first transfer position and delivers them to a second transfer position. The gluing device is arranged within an angular region of rotary motion of the vacuum drum between the first and second transfer positions. The vacuum drum moves labels past the gluing device. The label removal device removes either labels or label residues that remain on the vacuum drum in the angular region.
Claims18
An apparatus comprising a labeling unit for applying labels to containers, said labeling unit comprising a label removing device, a vacuum drum, and a gluing device, wherein said vacuum drum is driven to rotate along a first rotation direction about a drum axis, wherein said vacuum drum receives labels at a first transfer position, wherein said vacuum drum delivers said labels to a second transfer position, wherein said gluing device is arranged within an angular region of rotary motion of said vacuum drum, wherein said angular region of rotary motion of said vacuum drum extends between said first transfer position and said second transfer position, wherein said vacuum drum is configured to move labels past said gluing device, wherein said gluing device is configured to glue labels that are moved past said gluing device by said vacuum drum, wherein said label removal device is configured for removing at least one of labels and label residues that remain on said vacuum drum in said angular region, and wherein said label removal device comprises a belt-shaped element forming a closed loop and surrounding said vacuum drum with a first loop length over an angular region of rotary motion of said vacuum drum at least between said first transfer position and said second transfer position and forming at least a second loop length that follows the second transfer position and on which the belt-shaped element is spaced at a distance from a periphery of the vacuum drum.
A method for operating a labeling unit for applying labels to containers, said labeling unit comprising a label removing device, a vacuum drum, and a gluing device, wherein said vacuum drum is driven to rotate along a first rotation direction about a drum axis, wherein said vacuum drum receives labels at a first transfer position, wherein said vacuum drum delivers said labels to a second transfer position, wherein said gluing device is arranged within an angular region of rotary motion of said vacuum drum, wherein said angular region of rotary motion of said vacuum drum extends between said first transfer position and said second transfer position, wherein said vacuum drum is configured to move labels past said gluing device, wherein said gluing device is configured to glue labels that are moved past said gluing device by said vacuum drum, wherein said label removal device is configured for removing at least one of labels and label residues that remain on said vacuum drum in said angular region, said method comprising at least one of receiving labels that have been left behind on said vacuum drum or removing labels that have been left behind on said vacuum drum, wherein receiving labels that have been left behind on said vacuum drum comprising receiving by at least one belt-shaped element that partially surrounds said vacuum drum with a first loop length that forms one part of a loop, and that is spaced apart from said vacuum drum with a second loop length that forms another part of said loop.
