The present invention relates to apparatus for producing adhesive-backed labels, and more particularly, to a system for dispensing adhesive-backed labels in multiple operating modes.
Conventional apparatus for producing and dispensing adhesive-backed labels include: (i) a device for printing information/symbology on the face of a label supply, i.e., a web/spool of a label face/liner material, and (ii) a cutting apparatus for separating the label face/liner material from the web/spool i.e., to produce a single adhesive-backed/lined label. While some of the label producing apparatus provide a stack of individually-printed labels ready for an operator to remove the liner (also referred to as the “backing material”), other label fabrication systems (oftentimes including a device known as “peeler bar”) automatically separate the face material from the liner to provide an application-ready label. With regard to the former, it will be appreciated that the stack of labels facilitates application thereof at a subsequent time or at a remote location, i.e., not within the immediate vicinity of the label producing apparatus. However, the operator is tasked with removing the adhesive backed label from the liner at the time of application which can be a laborious/costly operation. With respect to the former, it will be appreciated that the automated system for separating the adhesive-backed label face from the liner can be complex, and does not provide the operator with the option of applying the label at a remote location. That is, an operator must apply individual labels immediately upon label dispensation.
Mailing machines are devices which may include a label fabrication and/or dispensing system for the purpose of applying postage to mailpiece envelopes. These machines often include an option to print and dispense postage indicia/franking symbology either; (i) directly on the face of a mailpiece envelope, or (ii) on an adhesive-backed label which can, thereafter, be applied to the mailpiece envelope. With respect to the latter, the option to print a postage indicia/franking label is often selected when the surface contour of the mailpiece envelope is irregular and printing directly on the face may result in a distorted image. Examples include envelopes having irregularly shaped content material, or those including a liner or layer to protect fragile content material (“bubble-wrap” protection).
These options are accommodated by a print station having at least one print head which is moveable, along rails or guides, from one feed path to another. In one operating mode, the print head is positioned in the feed path of a sealed/completed envelope to print on the face of the envelope, and, in another operating mode, the print head is positioned directly over the feed path of a supply/spool of label face/liner material. Once printed, the label is cut, accumulated and/or dispensed in the manner described above in connection with conventional label fabrication/dispensing systems.
In addition to the various shortcomings associated with conventional label fabrication/dispensing systems, mailing machines introduce the added complexity of printing currency on the labels which are fabricated. That is, inasmuch as the label fabrication systems commonly associated with mailing machines print currency, these systems must be highly reliable to prevent the operator from incurring additional cost as a result of a torn or damaged postage indica/franking label. It will be appreciated that, once debited from the vault of the mailing machine, a damaged or improperly printed/dispensed postage label cannot be easily/immediately credited without being validated by an authorized source, e.g., a Postal Authority.
A need, therefore, exists for a label fabrication and dispensing system which (i) accommodates multiple operating modes, i.e., labels dispensed with a liner intact or removed, (ii) facilitates the separation of the label face from the liner removal, (iii) minimizes complexity for added reliability and (iv) minimizes the propensity of damage to a postage indicia/franking label, i.e., when used in combination with a mailing machine.
A system is provided for dispensing adhesive-backed labels including a housing assembly defining a first dispensing outlet, a system for conveying a supply of label material along a feed path and operative to bi-directionally displace the label material along the feed path, and a peeler bar, positionable from a first position to a second position, to effect an abrupt directional change in the feed path thereof, and cause the face material to separate from the liner material. Separation of the face material from the liner material produces an application ready label. A processor is employed to control the bi-directional displacement of the conveyance system and position the peeler bar within the housing such that the label material is: (i) conveyed downstream of the peeler bar when the peeler bar is in the first position, and (ii) drawn back across the peeler bar to cause a trailing edge of the face material to separate form the liner material when the peeler bar is in the second position. Separation of the face material from the liner material produces an application ready label dispensed through the first dispensing outlet of the housing. In another operating mode, the label dispensing system produces a stream or stack of lined-labels which are dispensed through a second dispensing outlet for application at a subsequent time or at a remote location.
Further details of the present invention are provided in the accompanying drawings, detailed description, and claims.

A system for dispensing and/or fabricating adhesive-backed labels are described herein. The invention is described in the context of a system for dispensing printed labels, a removable module for dispensing printed labels, and a system for fabricating and dispensing postage labels. The inventive teachings are also described in the context of a mailing machine for printing postage indicia/franking labels, although, it should be appreciated that any label producing and/or dispensing apparatus may be employed. A mailing machine merely provides an illustrative example of one embodiment of the invention, and should not be considered limiting when interpreting the meaning and/or scope of the appended claims.
The mailing machine 10 and label dispensing system 20 of the present invention include a processor 24 which receives operator input through a conventional input device 26, e.g., a touch screen display, keyboard, etc., to control the various operations of the mailing machine 10 and label dispensing system 20. With regard to the mailing machine 10, these inputs may include information regarding the type of mailpieces being processed, their weight, (if the machine is not equipped with a scale, or weigh-on-the-way system), print resolution, vault information, encryption/security inputs, network information, etc. In addition to these inputs, the mailing machine 10 of the present invention includes an option to print postage indicia and/or franking symbology either: (i) on the face of the mailpiece envelope 16, or (ii) on the face of the postage label 22. This is achieved by mounting at least one of the print heads 28 on a moveable carriage 30/rail system 32 which extends orthogonally across the feed path FPE of the processed mailpiece envelope 16 or, the feed path FPS of a web/spool 36 of label material 38. More specifically, the processor 24 is operatively coupled to an actuator (not shown) in the print station 12 to reposition at least one of the print heads 28 along one of the feed paths FPE, FPS depending upon the option selected by the operator. In a first position P1 (shown in phantom lines), the print heads 28 are disposed across the feed path of finished mailpieces and print postage indicia directly on the face of the mailpiece envelope 16. In a second position P2, (shown in solid lines), the print heads 28 are positioned across the feed path FPS of the web/spool supply 36 to print the postage indicia on the face of the label material 38.
While not shown in the schematic illustrations, each feed path FPE, FPS includes a transport system for conveying the finished envelope 16 or supply of label material 38. An envelop transport system may include a series of rollers along an envelope transport deck 42 of the mailing machine 10 for conveying the finished mailpiece through the print station 12 to the stacking tray 14. Similarly, a label material transport system may include rollers (not shown) to pay-out the label material 38 along a label transport deck 44 through the print station 12 to the label dispensing system 20.
Before discussing the operation of the label dispensing system 20, it will be useful to provide a brief description of the various components and their arrangement within the mailing machine 10. In the described embodiment and referring to
The label dispensing system 20 includes a detachable housing 50 having a plurality of outlets D1, W, and D2 for dispensing (i) application-ready labels 22R (
In
The peeler bar 54 is generally cylindrical in shape and extends orthogonally across, or relative to, the feed path FP of the label material 38, but may include a convex peripheral surface CS along its length to impart a complimentary shape to the label material 38 as it passes over the peeler bar 54. While this will be described in greater detail hereinafter, suffice it to say at this juncture that the shape imparts additional stiffness to the adhesive-backed label 22 which facilitates separation and handling of the label 22.
The conveyance system 70 includes a pivotable deflector guide 72 disposed between a first pair of rollers 74 and a second pair of rollers 76. In the described embodiment, the deflector guide 72 is integrated with, and extends between, the pivot arms 56 which mount the peeler bar 54, although it should be appreciated that the deflector guide 72 may be independently mounted to the housing 50 and positioned by a separate actuation device. The deflector guide 72, therefore, pivots along with the peeler bar 54 and is controlled by the processor 24 through the rotary actuator 58 and encoder 60. In the illustrated embodiment, the first pair of rollers 74 are vertically oriented, i.e., rotate about axes which lie in a vertical plane, and define a first drive nip N1 which displaces the label material 38 along a substantially horizontal feed path FP. The second pair of rollers 76 are horizontally oriented, i.e., rotate about axes which lie in a horizontal plane, and define a second drive nip N2 which displaces the label material 38 along a substantially vertical feed path FP. While the first and second drive nips N1, N2 are substantially orthogonal to change the direction of the feed path from horizontal to vertical, it should be appreciated that other orientations are contemplated depending upon the location of the various outlets D1, W, D2.
Each pair of rollers 74, 76 may be driven by respective rotary drive motors M1, M2 which are controlled by the processor 24. The processor 24 can drive each of the motors M1, M2 and the respective rollers 74, 76 in either direction, i.e., to bi-directionally displace the label material 38 along the feed path FP and at the same or at variable speeds relative to each other. In this way, the label material 38 may be paid-out or drawn back at different rates of speed to increase or decrease the length of label material between each of the drive nips N1, N2.
Furthermore, the deflector guide 72, in combination with the rollers 74, 76 may be positioned to direct the label material 38, or liner material 48 thereof, from one of the pairs 74, 76 to the other of the pairs 74, 76, through one of the dispensing outlets D1, D2 or through the waste outlet W. Similar to the peeler bar 52, the deflector guide 72 is positionable from a first position (shown in solid lines in
While the supply of label material 38 may include precut label material, i.e., a kiss-cut penetrating through the face material 46, the label fabrication system 20 may include a cutting apparatus 80 for the purpose of cutting the face material 46 to any length. That is, since the label transport rollers and drive rollers 74, 76 control the amount of label material 38 which is paid-out from the label supply 36, each postage label 22 may be cut to any size, e.g., from two (2) inches to eight (8) inches, depending upon the information to be printed. For example, some labels 22 may contain only the postage indicia while others may include barcode security or other symbology. In the described embodiment and referring to
In addition to the first cutting apparatus 80, a second cutting apparatus 90 may be disposed upstream thereof, to sever the label material 38, i.e., cut through the liner material 48 or through the combined face and liner materials 46, 48. This cutting apparatus 90 may be disposed in either the mailing machine 10 or in the label dispensing system 20 and may be controlled by the same processor 24 employed to control the position of the peeler bar 54, the conveyance system 70, and the first cutting apparatus 80. As will be described in greater detail when discussing the operation of the mailing machine 10 and label dispensing system 20, the second cutting apparatus 90 is principally employed to discard waste material following the dispensation of an application ready label 22R.

In another embodiment of the invention, separation of the application ready label 22R may be further enhanced/augmented by driving the first and second pairs of rollers at differential speeds. That is, the processor 24 may issue a command signal to drive motor M1 at a higher speed than motor M2, thereby driving the first pair of rollers 74 at a higher speed than the second pair of rollers 76. Accordingly, a tensile load is imparted to the liner material 48 as it passes over the peeler bar 54. The increased tensile load enhances frictional engagement with the peeler bar 54 and, accordingly, separation of the printed label 22R from the underlying liner material 48.

In summary, the system for dispensing labels 22 operates in any of three modes to dispense printed labels 22R in a condition ready for application, waste material 38W, and lined labels 22L which may be used at any time or at any location produced. A first mode of operation dispenses application ready labels 22R through a first dispensing outlet D1. The application ready label 22R is dispensed upwardly by separating the trailing edge of the adhesive-backed label 22R from the protective liner material 48. The system, therefore, presents the label 22R in an optimum orientation for immediate application. A second mode of operation discards waste material 38W through a bottom/lower waste outlet W and uses gravity to augment collection and removal of waste material 38W, i.e., into a waste receptacle. A third mode of operation dispenses lined labels 22L though a second dispensing outlet D2, disposed between the first dispensing and waste outlets D1, W. The lined labels 22L may be dispensed as a stream of tandemly arranged printed labels 22L or stacked for individual use at a subsequent time or at a remote location.
It is to be understood that the present invention is not to be considered as limited to the specific embodiments described above and shown in the accompanying drawings. The illustrations merely show the best mode presently contemplated for carrying out the invention, and which is susceptible to such changes as may be obvious to one skilled in the art. The invention is intended to cover all such variations, modifications and equivalents thereof as may be deemed to be within the scope of the claims appended hereto.
