Abstract
An automatic high speed labeling machine with an improved label stripper is provided capable of applying 700 to 1,000 labels to individual produce items in a single lane, without tearing the label carrier strip. The improved label stripper has a contoured surface wherein only the center section contacts the label carrier strip. The edges of the carrier strip are prevented from contacting the label stripper surface.
Claims18
An automatic, high speed labeling machine used to apply labels to produce, wherein a label applicator having a plurality of bellows carried on a rotary head includes a label stripper to strip individual labels from a label carrier strip and transfer said labels onto the tip of a single bellow, and thereafter onto individual items of produce wherein said label carrier strip has first and second edges, is drawn across said label stripper surface to separate individual labels from the center of said label carrier strip, and wherein said label carrier strip periodically becomes misaligned relative to said label stripper surface, the improved label stripper characterized by:
- said label stripper having a body, two mounting ears and a contoured surface, said contoured surface including a central stripping segment and first and second separation segments.
- said central stripping segment is positioned on the center of the pathway of said carrier strip to engage and strip said labels as said carrier strip is drawn across said label stripper
- said first and second separation segments are positioned laterally on opposite sides of said central stripping segment, and both separation segments have surfaces inclined in a direction away from the path of said carrier strip, whereby as a label is stripped by said central stripping segment, said first and second edges of said carrier strip are separated from said contoured surface by said separation segments and do not contact said contoured surface of said label stripper, minimizing tension in said first and second edges of said carrier strip and maximizing tension in the center of said carrier strip
A method for use in a high speed, automatic labeling machine used to apply labels to produce, wherein a label carrier strip having first and second edges and carrying a plurality of labels along its center is drawn across a label stripper to separate individual labels from said carrier strip, wherein said label stripper has a body, two mounting ears and a label stripping surface, wherein said label carrier strip periodically becomes misaligned relative to said label stripper, and wherein said misalignment causes tearing of said carrier strip, said method characterized by:
- forming a contoured surface of said label stripper with a center stripping segment and first and second separating segments,
- causing said center of said carrier strip to continuously engage said center stripping segment of said label stripper to strip labels,
- simultaneously causing said separation segments of said contoured surface to continuously separate the first and second edges of said carrier strip from said contoured surface, allowing said edges to move past said label stripper without running against it,
- whereby tension in the center of said carrier strip is maximized to increase efficiency of label removal, and tension in said first and second edges of said carrier strip is minimized to reduce tearing of said carrier strip
