Abstract

A device for labeling flat objects, such as compact cassettes, video cassettes or the like with a supply stacker for the transfer of label holder-arranged labels. The label holders are provided with vacuum impingeable suction bores for label transfers and with object recess-and label perforation-and border-matching beveled projections, plus a device for effective label adhesion. The device includes a radially-mobile arrangement of label holders on at least one step-by-step revolving rotary-run head. The holders move from the head to stationary functional stages, namely, a transfer stage, where the label is made to stick, and an applicator stage for applying labels to objects. A conveyor chain is provided for continually passing by the rotary-run head with object sliding cams. The applicator stage is equipped with a platform for lifting objects from the continuous-run conveyor chain above the level of the cams.

Dependent claims

In a device for the labeling of tape cassettes, with a conveyor conveying the cassettes linearly on edge, with a supply magazine from which the cassettes are guided to the conveyor, and devices for application of the labels arranged opposite each other on both sides of the conveyor, the improvement comprising:

each label application device having radially moving label holders (36) rotating rhythmically about a vertical axis, with vertical suction surfaces, and two pinheads (44) penetrating the suction surfaces, retractable against spring tension radially behind the suction surface, and adjusted to recesses of the cassette and perforations of the labels, a supply stacker (40), said pinheads being movable with respect to said supply stacker, an applicator stage (42) for adhesive liquid and depositor stages (20);
the conveyor being constructed as a continuously rotating conveyor chain (16) having cams (18) for inserting the cassettes;
and an elevating platform being arranged in the depositor stages (20) which lifts the cassettes via the cams (18) into the operating range of the label holders (36).
