Abstract
A labeling machine, which includes a conveyor of containers to be labeled along an advancement path and at least one labeling unit arranged along the advancement path and provided with a respective transfer drum that can move in rotation about its own axis, with respect to a supporting base, and which is adapted to receive, in adhesion to its lateral surface, from a feeder unit, labels to be applied to the containers, at a feeding station, and to transfer the labels received at the feeding station to respective containers that arrive from the conveyor at a transfer station which is angularly spaced apart from the feeding station about the axis of the transfer drum; at least one portion of a sector of the lateral surface of the transfer drum is rotatably movable, with respect to the remaining part of the transfer drum.

A labeling machine, comprising a conveyor of containers to be labeled along an advancement path and at least one labeling unit arranged along said advancement path and provided with a respective transfer drum that can move in rotation about a drum axis, with respect to a supporting base, and which is adapted to receive, in adhesion to a lateral surface thereof, from a feeder unit, labels to be applied to said containers, at a feeding station, and to transfer the labels received at said feeding station to respective containers that arrive from said conveyor at a transfer station which is angularly spaced apart from said feeding station about the drum axis, on the lateral surface of said transfer drum at least one sector being defined which extends along at least one portion of a circumferential extension of the lateral surface of said transfer drum and is adapted to accommodate, in each instance, a single label to be transferred to a single one of the containers, wherein at least one portion of said at least one sector is rotatably movable, with respect to a remaining part of said transfer drum, about an oscillation axis, which is substantially parallel to the drum axis, in order to pass from a receiving position, in which said at least one portion is arranged at a first angular distance from the drum axis, to a transfer position, in which said at least one portion is arranged, with at least one part thereof, at a second distance, greater than said first distance, from the drum axis, and vice versa;
- wherein said transfer drum comprises a base structure that supports at least one shell-like body which defines at least one part of said at least one sector, said at least one portion of said at least one sector comprising an oscillating body, which is hinged with respect to said base structure about said oscillation axis;
- wherein said oscillating body is hinged with respect to said base structure substantially at an end of an extension thereof that is arranged at the rear with respect to a direction of rotation of said transfer drum;
- wherein said at least one portion of said at least one sector is in said receiving position, at least when the at least one portion passes at said feeding station, during the rotation of said transfer drum about the drum axis;
- wherein said at least one portion of said at least one sector is in said transfer position, at least when it passes at said transfer station, during the rotation of said transfer drum about the drum axis.
A labeling machine, comprising:
- a conveyor for conveying a container to be labeled along an advancement path;
- a first labeling unit arranged along said advancement path and provided with a transfer drum that is movable in rotation about a drum axis, with respect to a supporting base, and which is adapted to receive, in adhesion to a lateral surface thereof, from a feeder unit, a label to be applied to said container, at a feeding station, and to transfer the label received at said feeding station to said container that arrives from said conveyor at a transfer station which is angularly spaced apart from said feeding station about the drum axis;
- wherein the lateral surface of said transfer drum includes a first sector that extends along at least one portion of a circumferential extension of the lateral surface of said transfer drum and is adapted to accommodate an entirety of a single label to be transferred to the container, wherein at least one portion of the first sector is rotatably movable, with respect to a remaining part of said transfer drum, about an oscillation axis, which is substantially parallel to the drum axis, in order to pass from a receiving position, in which said at least one portion is arranged at a first distance from the drum axis, to a transfer position, in which said at least one portion is arranged at a second distance, greater than said first distance, from the drum axis;
- wherein said transfer drum comprises a base structure that supports at least one shell-like body which defines at least one part of said first sector, said at least one portion of said first sector comprising an oscillating body, which is hinged with respect to said base structure about said oscillation axis;
- wherein said oscillating body is hinged with respect to said base structure substantially at an end of an extension thereof that is arranged at the rear with respect to a direction of rotation of said transfer drum;
- wherein said at least one portion of said first sector is in said receiving position, at least when the at least one portion passes at said feeding station, during the rotation of said transfer drum about the drum axis;
- wherein said at least one portion of said first sector is in said transfer position, at least when the at least one portion passes at said transfer station, during the rotation of said transfer drum about the drum axis.
