Abstract
An improved labeler includes a label base and a label cassette with the footprints of the labeler base housing and the label cassette frame being substantially the same size. An electronically-controlled drive mechanism is contained drive mechanism is contained within the labeler base housing and is operated intermittently to synchronously drive a mechanism for feeding labels to be picked up by a bellows wheel, and the bellows wheel.
Claims12
A labeler for applying labels on a carrier to articles comprising:
- a label feed mechanism for feeding labels;
- a rotatable bellows wheel having individual bellows spaced around the periphery thereof;
- a vacuum source and a pressure source that may be selectively connected to each individual bellows such that each of the individual bellows is subjected to pressure when adjacent a label application position and subjected to vacuum for picking up a label from the label feed mechanism and retaining a label on one of the individual bellows;
- a sensor for detecting an article and providing an indication of such detection;
- and
- an electronically-controlled drive mechanism substantially contained within the labeler to drive said label feed mechanism and to rotate said bellows wheel to permit it to effect the depositing of a label retained on one of the individual bellows on an article positioned at the label application position upon receipt of an indication from said sensor,
- wherein said electronically-controlled drive mechanism operates intermittently to advance the label feed mechanism and the bellows wheel in response to the detection of an article.

A labeler for applying labels on a carrier to articles comprising:
- a label cassette comprising:
- a cassette frame having a lower surface,
- an apparatus fixed to the cassette frame for supporting a reel of labels on a carrier, and
- a label transport mechanism mounted to said cassette frame for unwinding a strip of labels on the carrier from the reel and presenting labels to a predetermined location, the label transport mechanism including a first drive sprocket which is engageable through the lower surface of the cassette frame to drive the label transport mechanism;
- and
- a labeler base to which said label cassette may be removably mounted, the labeler base comprising:
- a housing having a footprint and an upper surface to receive the cassette frame,
- a rotatable bellows wheel supported by the housing and comprising a series of radially-spaced, label-receiving bellows each adapted to selectively receive a label presented to said predetermined location, the bellows wheel having a second drive sprocket associated therewith to rotate the bellows wheel,
- a sensor for detecting the presence of an article and for providing an indication of such detection;
- and
- a drive mechanism substantially contained within the footprint of said housing comprising at least one electronically-controlled motor, the drive mechanism operating intermittently and synchronizing the intermittent driving of the first and second drive sprockets to advance the carrier strip and the bellows wheel when the presence of an article is detected by said sensor.
