Abstract

ABSTRACT

A method and apparatus for using linerless label stock in a commercial packaging labeling machine is described. A print roller is positioned in close proximity to the print head for receiving linerless label stock from a supply reel. Spaced from the print roller is a peel bar comprising a relatively small diameter rod. An endless belt of silicone coated fabric travels around the print roller and peel bar. As label stock is introduced to the print head, it adheres to the endless belt and is transported between the print head and roller whereupon it is printed. As the endless belt and label stock reaches the peel bar the abrupt change of direction of the belt causes the belt and label stock to separate, whereupon the label stock is transported away from the printer in a substantially linear direction of travel.

Description

2129~68 ~ Docket No. 06593-1342-Cl PATENT

PRINTING SYSq~EM EOR LINERLESS LABELS
BACKGROUND OF THE INVENTION

~ This is a continuation-in-part of U.S. Application ? S Serial No. 08/101,512 filed August 2, 1993.

1. Field of the Invention The present invention relates to the printing of merchandising labels for wrapped packages and, more - particularly, to the printing and conveying of linerless , 10 labels.

:r 2. De~cription of the Prior Art :
In product merchandising, such as in the supermarket bu~ine~s for example, products are wrapped typically in stretch or shrink film, then conveyed to a labeler which automatically prints and attaches a label to the product package qiving price or other information about the product.
The labels are provided in the for~ of a narrow continuous strip of paper stock and are joined at tearable perforations so that individual labels may be printed and separated from the strip for attachment to the package.
Label stock of the type currently in use is supplied in roll form. The labels are made from thermosensitive paper and have an adhesive backing on them so that they will .
adhere to the plastic wrapping of the package. In order to keep the labels from sticking to themselves while in roll form or during handling, the labels are mounted on a continuous backing, or liner. The typical liner is a paper '' .

`-:

- 21290~
Docket No. 06593-1342-Cl material coated on one side with silicone. The silicone coating allows the labels to be readily separated from the liner prior to attachment to a package.
A disadvantage of using conventional label stock having a liner is that the spent liner must be collected and disposed of. This typically involves providing a take-up ; reel for storing the used liner. The reel must be changed periodically in the opera~ion of the labeling machine and the full reel must be discarded or replaced with an empty reel, involving down time of the label machine.
Label stock is available which is linerless. That is, ~' the label material is supplied in roll form but without a silicone-coated backing paper. The labels are coated on their print side with silicone so that their adhesive side will not stick appreciably to the print side when in roll form. A problem with using linerless label stock is that the adhesive side of the labels will adhere to the conveying members when the label stock is transported through the printer. This is particularly a problem at the thermal ~ 20 print head where the label must be pressed against the print ;~ head to obtain an acceptably printed label. The typical , means for pressing the label against the print head is neoprene roller juxtaposed next to the print head. Without `~ a liner, the label stock will adhere to the print roller and - 25 be incapable of being transported to the package.

SUMMARY OF THE INVENTION -. -It is therefore an object of the invention to provide a m~thod and apparatus for using linerless label stock in a commercial package labeling machine. In accordance with the -invention, a print roller is positioned in close proximity to the print head for receiving linerless label stock from a ~` ' :

An endless belt of silicone coated fabric travels around the print roller and peel bar. As label stock is introduced to the print head, it adheres to the endless belt and is transported ; between the print head and roller whereupon it is printed.
As the endless belt and label stock reaches the peel bar, the abrupt change of direction of the belt causes the belt and label stock to separate, whereupon the label stock is transported away from the printer in a substantially linear direction of travel.

BRIEF DESCRIPTION OF THE DRAWING

The present invention will be better understood from the following description of a preferred embodiment thereof taken in connection with the accompanying drawing in which:
FIG. 1 is a schematic view of a prior art label ~- printing apparatus for use with conventional label stock having a liner; and .
FIG. 2 is a schematic view of a label printing ' 20 apparatus in accordance with the invention for use with ~`~ linerless label stock.
i FI~. 3 is a schematic view of an apparatus in ;~ accordance with another embodiment of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Referring initially to FIG. 1, a prior art label printing apparatus, designated generally by the reference numeral 10, includes a conventional thermal print head 12 disposed in close proximity to a print roller 14. Label ` stock 16 is supplied from a supply reel 1~. The label stock ; -3-~:`
.~

~1290i~8 Docket No. 06593-1342-Cl 16 includes thermally sensitive paper 20 backed by a relatively non-stick liner 22. When the printing apparatus 10 is in operation, the label stock 16 is fed between ~he print head 12 and print roller 14 whereupon appropriate indicia is printed on the label paper 20. In the configuration illustrated, the print side of the label stock 16 is facing downwardly while the liner 22 is on the upward side of the label stock 16.
After the label stock 16 passes between the print head 12 and roller 14 the label stock travels to a peel bar 24 where the liner 22 is stripped from the label paper 20. The used liner 22 then proceeds around the peel bar 24 to a take-up reel 26 on which it is stored for later disposal.
The label paper 20 continues to advance, with its adhesive ; 15 side exposed, to a package labeling station (not shown).
Turning now to FIG. 2, a label printing apparatus in accordance with the invention is designated by the reference numeral 30 and includes a conventional thermal print head 32 positioned adjacent a print roller 34. Label stock 36 of the linerless type is provided from a sùpply reel 38 with its adhesive side up, as viewed in FIG. 2. The label stock 36 passes between the print head 32 and print roller 34 where it is intercepted by an endless belt 40. The endless belt 40 passes around a peel bar 42, the print roller 34 and -~
an idler pulley 44. The idler pulley 44 is tensioned by a -; suitable biasing means ~6 so that the belt 40 remains taut as it is driven by the print roller 34.
`~ ~he belt 40 is preferably formed from a fabric material coated on its outward surface with silicone. A porous roller 48 filled with liquid silicone may be positioned in -contact with the belt 40 to apply a continuous film of - silicone to the belt surface.
~ --4- ~

', ~

- 212``~8 Docket No. 06593-1342-Cl In operation of the apparatus 30 it can be appreciated that as the strip of linerless label stock 36 passes between the print head 32 and roller 34, where it is intercepted by the endless belt 40, the adhesive of the labels 36, which is facing upwardly as viewed in FIG. 2, causes the labels 36 to adhere to the belt 40 and be transported to the peel bar ~2.
At the peel bar 42 the belt 40 makes an abrupt change of direction causing the belt 40 to separate from the label strip 36, whereupon the strip of labels 36 is free to proceed substantially in a straight line from the supply reel 38 through the printer 32 and then to a label applying station (not shown). The belt 40 thus serves as a temporary liner for the label stock 36 during the printing process and ; completely eliminates the need for linered label stock.
` 15 FIG. 3 illustrates another embodiment of the invention in which the belt passes around idler rollers 44 and 45 and the peel bar 42 is located outside the endless belt 40 adjacent to the print roll 34 where the peel bar functions to direct the labels 36 to the label applying station. In this embodiment, the print roll 34 has a small enough diameter that the labels separate from the belt 40 as the belt passes around the print roll 34 without positioning the peel bar 42 within the belt 40. Because the labels separate from the belt as the belt passes around the print roll and the peel bar functions merely to direct the labels to the label applying station, in a further embodiment of the invention, the peel bar can be eliminated altogether and other means can be used to direct the labels to the label applying station.
