Abstract
A device for transferring labels in a labeling machine with at least two retaining elements for holding labels, with the retaining elements being mounted offset in the circumferential direction around a gripper cylinder axle, and a mechanical control means configured to change the relative speed between the retaining elements in the circumferential direction of the gripper cylinder.
Claims13
A device for transferring labels in a labeling machine, comprising at least two retaining elements for holding labels, the retaining elements being mounted offset in the circumferential direction around a gripper cylinder axle of a gripper cylinder, and mechanical control means which are configured to change the relative speed between the retaining elements in the circumferential direction of the gripper cylinder;
- the retaining elements comprising at least two elements which are connected in a lever type fashion around an axle which is essentially parallel to the gripper cylinder axle, wherein an upper element is configured to grip labels and is guided on a circular path, and wherein a lower element is guided on a control cam;
- and
- the upper element comprising a slide with at least one guide roller, such that the upper element is guided on the circular path.
A method of transferring labels in a labeling machine with a device comprising at least two retaining elements for holding labels, the retaining elements being mounted offset in the circumferential direction around a gripper cylinder axle of a gripper cylinder, and mechanical control means which are configured to change the relative speed between the retaining elements in the circumferential direction of the gripper cylinder;
- and including a pallet rotor with several pallets which are provided in a first pitch at the pallet rotor, with the pallet rotor being rotatable about an axle which is essentially parallel to the gripper cylinder axle, with a container carrousel with several rotary tables with containers which are provided in a second pitch, comprising, after the acceptance of a label from the pallet by the retaining elements, adjusting the retaining elements to the second pitch of the container carrousel by changing the relative speed between the retaining elements in the circumferential direction of the gripper cylinder.
