Abstract
In the labeling of articles such as bottles by feeding the articles to a labelling machine having label pickup means, picking up labels from a label box, successively applying such labels to the articles, and periodically replacing the label box when empty with a full label box, the improvement which comprises replacing the empty label box during the time interval between successive label pickups without stopping the machine. An apparatus therefor includes two label boxes disposed alongside one another, guide means for the boxes so as to permit them to move together transversely to the direction in which labels are stacked in the boxes, and means permitting retracting and advancing in label stacking direction of that label box which is in active position.
Claims9
In a labelling machine having means for feeding articles to be labelled, a label supply, label pick up means for picking up a label from the supply, means for applying the the machine, and means for replacing the label supply when exhausted, the improvement wherein said label supply comprises at least three label boxes disposed alongside one another at the pickup point so as to be successively displaceable in one direction, the label boxes being releasably joined to one another by a dovetailed joint formed along their side walls, and the means for replacing the label supply when exhausted comprises guide means for the boxes so as to permit them to move together transversely to the direction in which labels are stacked in the boxes, and means permitting retracting and advancing in label stacking direction of that label box which is in active position.
An apparatus according to claim 16, wherein for transverse movement an endless chain is provided with extended hinge pins carrying supporting means for the label boxes.
An apparatus according to claim 8, wherein the supporting means are guided by a compression spring set onto a section of the extension of the chain hinge pin, said spring abutting at one end against one of the sides of the chain links and at the other end against an interior wall of the supporting means whose opposite interior wall is caused to abut on the other side of the chain links by the action of the compression spring.
