Abstract

A case labeler for moving a label from a holding magazine in a path to sweep over a glue applying applicator and continue into a position where the glue side of the label is presented to a case moving on a conveyor and acting to trip control switches which cause the glue applicator to move into the sweep path of the label and cause a label carrier head to pick a label off the magazine by negative pressure and begin a sweeping motion in a well defined path. The motion of the carrier head in its sweep path is to rotate the label from a first position at the magazine through a partial amount of rotation to pass the label surface over the applicator and through the remainder of the rotation to present the glue side of the label to the path of case movement. The case labeler includes an applicator which is free to move in a manner such that it may apply glue substantially uniformly over the label surface as the head carries the label in a continuous sweep between the magazine and the path of conveyance for the cases.

Dependent claims

A case labeler for presenting an adhesive label in the path of movement of a case requiring a label, said labeler comprising:

a frame adjacent the path of movement of cases;
a label supporting head;
a magazine for supporting a supply of labels;
adhesive supply means having an applicator member for transferring adhesive from said supply to the labels;
operating means connected to said head for moving said head in a path from said magazine and past said applicator member into a position in the path of movement of a case;
vacuum generating means connected to said head for permitting said head to engage and pull a label out of said magazine and retain label engagement past said adhesive applicator member and into a position in the path of a case;
and control means operatively connected to said operating means and said vacuum generating means and including first means responsive to the approach of a case for energizing said operating means to effect movement of said head between said magazine and a position in the path of case movement, and second means responsive to the advance of a case to the position of said head in the case path for ending the generation of vacuum so the label is released to the case and adhesively secured thereto and causing said operating means to return said head to said magazine.
