摘要:
A device for changing the angular relation between a carousel conveyor and a label applying apparatus including a support frame to which an internal hollow shaft and an external hollow shaft are mounted, the shafts being coaxial and respectively connected by a cogwheel to the drive shaft of the conveyor and to the drive shaft of the label applying apparatus, the shafts being coupled to each other by a rotatable coaxial joint which moves axially of the shafts.
摘要:
An apparatus (1) and a method for feeding a continuous tape (3) for forming labels (2) is disclosed, according to which a pair of rollers (5) advances the tape at an advancing speed that is calculated on the basis of the rotation speed of one cutting roller (6) that cuts the tape into labels, (2) at a signal that is indicative of the cut that occurred and at a positioning error of an actual image present on the tape with respect to a reference image. The real image is detected by a linear camera (9) or by a matrix camera.

摘要:
A device for forming and transferring a sleeve-like label to a container to be labeled, comprising a feeder designed to feed a portion of heat-shrink film to at least one forming spindle and means for wrapping the portion of heat-shrink film around the lateral surface of the forming spindle, feeder means being provided which are adapted to move, along an approach path that has at least one component perpendicular to the axis of the forming spindle, the container to be labeled to a labeling position arranged below the forming spindle and pick-up means adapted to pick up the container with the sleeve-like label fitted around the respective lateral surface along a path for removal from the labeling position which has at least one component perpendicular to the axis of the forming spindle.
摘要:
The present invention relates to an unreeling assembly, particularly for labeling devices, comprising a supporting frame for at least two reels of continuous film which are supported by a respective reel support, which can be actuated to rotate about an unreeling axis of the reel by a respective servomotor, and a motorized traction drum, which is designed to unreel the continuous film from one of the at least two reels of continuous film, between the reel of film being unreeled and the traction drum there being at least one element for tensioning the continuous film, the tensioning element being movable, with respect to the supporting frame, along a respective movement path, characterized in that it comprises control elements which operate on the servomotor and are adapted to control the position of the tensioning element along the respective movement path.
