Patent Application

Pressure sensitive labels (referred to herein as labels) are typically supported by a liner with a release system—typically a silicone system—(referred to herein as a liner) and wound into a roll on a core.
In current label dispensing systems (also referred to as dispensers, for example), a standard peel plate is provided for separating the labels 120 from the liner 110.
In such a conventional system, the second side of the liner is unused for labels to be disposed thereon, thereby increasing the amount of liner needed for label disposition and removal.
Systems for dispensing labels from a liner are described herein. In some embodiments, the system contains a peel plate containing at least one rod.
In some embodiments, the system includes an unwind roller for receiving a first end of the liner; a rewind roller for receiving a second end of the liner; and a peel plate over which the liner passes between the unwind roller and the rewind roller, wherein the peel plate is designed to reduce friction compared to a standard peel plate. In some embodiments, the peel plate includes a low friction or friction reducing peel plate for a label dispensing system over which a liner is moved is provided, the liner having labels disposed thereon.
In some embodiments, the systems include an unwind roller for receiving a first end of the liner; a rewind roller for receiving a second end of the liner; and a peel plate with at least one rotating rod over which the liner passes between the unwind roller and the rewind roller. In some embodiments, the peel plate contains a single rotating rod. In some embodiments, the peel plate includes a rotating rod over which a liner is moved, the liner having labels disposed thereon. In some embodiments, the peel plate exhibits reduced or low friction.
In still other embodiments, the system includes an unwind roller for receiving a first end of the liner; a rewind roller for receiving a second end of the liner; and a peel plate with at least one hollow, perforated rod. In some embodiments, the peel plate contains one hollow, perforated rod. The perforations can be any shape or size. The rod may rotate or be fixed. The rod can be connected to a compressed gas source, such as compressed air. Gas passing through the perforations creates an “air cushion” over which the liner moves; the liner does not contact the rod thereby reducing friction.
In still other embodiments, an unwind roller for receiving a first end of the liner; a rewind roller for receiving a second end of the liner; and a peel plate with at least two rods and a conveyor belt or strap. The belt or strap passes over the at least two rods. In some embodiments, the rods are rotating. The liner passes over the belt or strap, rather than contacting the rods, thereby reducing friction.
The configurations or designs described above with respect to the peel plate can be used alone or in combination.
Methods of dispensing labels using the systems described herein are also disclosed. In some embodiments, the method includes moving the liner over one or more of the peel plates described above. In other embodiments, the method includes moving the liner over a friction reducing peel plate.
This summary is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. This summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.
The foregoing summary, as well as the following detailed description of illustrative embodiments, is better understood when read in conjunction with the appended drawings. For the purpose of illustrating the embodiments, there is shown in the drawings example constructions of the embodiments; however, the embodiments are not limited to the specific methods and instrumentalities disclosed. In the drawings:
Various implementations include systems and methods of dispensing labels from a two-sided laminated liner. These systems and methods make more efficient use of the liner because the liner can be used twice instead of once.
In some embodiments, a liner, such as the liner 410, having silicone disposed on the first and second sides thereof and a face material adhered to each side. Although silicone is described as being used, it is contemplated that other materials known in the art may be used. The face material is die cut into the shape of the labels 420, 425, and any sacrificial face material surrounding and/or in between the labels 420, 425 may or may not be removed from the liner 410. The liner 410, with the labels 420, 425 thereon, may be rolled on a core which in its turn is put on the unwind roller.
To dispense the labels 420 from the liner 410, one end of the liner 410 is coupled to the rewind roller 520, and the rewind roller 520 pulls the liner 410 from the unwind roller 510. As the liner 410 is pulled off of the unwind roller 510 and onto the rewind roller 520, a second side of the liner (the side of the liner 510 having the labels 425 disposed thereon) passes over the peel plate 200, the peel plate 200 having a narrow-edged portion 210. Pulling the liner 410 over the peel plate 200 causes the labels 420 on the first side of the liner 410 to separate from the liner 410.
However, it has been determined that side of the liner 410 having the labels 425 disposed thereon, which would be separated from the liner 410 in a subsequent (i.e., second) pass of the peel plate 200, incurs label curl and scuffing as a result of the liner 410 being moved/pulled over the peel plate 200 during the first pass in which the labels 420 are separated from the liner 410. In other words, pulling the liner 410 over the peel plate 200 in a first pass caused the liner 410 and labels 425 on the second side of the liner 410 to curl. In particular, because there are labels on two sides of the liner 410, the labels 425 that are dispensed during the second round of dispensing (i.e., the labels 425 on the second side of liner 410) run over the peel plate 200 during dispensing of the labels 420 on the first side of the liner 410. The labels 425 on the second side of the liner 410 curl after they have been pulled over the peel plate 200, much like the effect of curling a ribbon by pulling the ribbon over the blade of a pair of scissors at a sharp angle.
In order to reduce the friction over the liner 410 during label 420 dispensing, which would thereby reduce or eliminate the curling and scuffing effect of the liner 410 for subsequent (second side) label 425 dispensing, the standard peel plate 200 is replaced by a friction reducing peel plate.
Pulling the second side of the liner 410 over a reduced friction surface when the labels 420 on the first side are being dispensed reduces the curl of the liner 410 and the labels 425 on the second side of the liner 410. Moreover, in some implementations, pulling the liner over a reduced friction surface (such as a rotating rod) instead of the standard peel plate 200 prevents scuffing or dust (e.g., silicone dust) from being scraped from the second side of the liner 410 during the first round of label 420 dispensing.
In some embodiments, the rotating rod 610 is cylindrically shaped and has a central axis about which the rod rotates. The rod may be solid, hollow, or both. In the implementation shown in
Although a single axle is described above as extending through the rod 610, in other implementations, the rod 610 may be coupled to the bosses using a first axle and a second axle that are separate from each other. In such implementations, the first axle extends from one end of the rod 610, the second axle extends from a second end of the rod 610, and distal end portions of the axles are rotatably coupled to the bosses. The first and second axles extend along the rod's central axis, and bearings may be disposed between the external surface of each end portion of each axle and the inner surfaces of the openings defined by the bosses.
In other embodiments, end portions of the rotating rod 610 may be rotatably coupled to the bosses directly (i.e., without axles). In this alternative implementation, bearings may be disposed between the external surface of each end portion of the rod 610 and the inner surfaces of the openings defined by the bosses.
Although the subject matter has been described in language specific to structural features and/or methodological acts, it is to be understood that the subject matter defined in the appended claims is not necessarily limited to the specific features or acts described above. Rather, the specific features and acts described above are disclosed as example forms of implementing the claims.
