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.
Claims1
A labeler for applying labels on a carrier to articles transported by a conveyor 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 the 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 individual bellows;
- a sensor for detecting an article and providing an indication of such detection;
- and
- an electronically-controlled drive mechanism 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 the individual bellows on an article positioned at the label application position upon receipt of the 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.
