Definitions

  • the present invention relates generally to the retail industry and, more particularly, to devices for securing an article of commerce to its respective packaging.
  • an article of commerce is commonly secured to packaging in order to, inter alia, protect the article during transport, minimize the risk of article theft or tampering, and display the article at the point-of-sale.
  • Packaging used in the retail industry is often constructed out of a thick, paper-based material, such as paperboard, chipboard, cardboard or the like.
  • Various techniques are known in the art for securing an article of commerce to a paper-based packaging material.
  • plastic fasteners are often used to secure an article to its respective packaging.
  • U.S. Pat. No. 4,039,078 to A. R. Bone the disclosure of which is incorporated herein by reference, there are disclosed several different types of plastic fasteners.
  • Each plastic fastener described in the '078 patent is manufactured in a generally H-shaped configuration, with two shortened parallel cross-bars, or T-bars, being interconnected at their appropriate midpoints by a single, thin, flexible filament which extends orthogonally there between.
  • Plastic fasteners of the type described above are commonly fabricated as part of a continuously connected supply of fastener stock, which is also commonly referred to in the art simply as ladder stock due to its ladder-like appearance.
  • ladder stock that well known in the art is presently manufactured and sold by Avery Dennison Retail Information Services LLC, through its Fastener Division in Fitchburg, Mass. under the PLASTIC STAPLE® and ELASTIC STAPLE® lines of plastic fasteners.
  • This brand of ladder stock is produced from one or more flexible plastic materials, such as nylon, polypropylene and the like, and includes a pair of elongated and continuous side members, or rails, which are interconnected by a plurality of equidistantly spaced cross-links.
  • a fastener dispensing device of the type as described above can be used to secure an article to its corresponding packaging.
  • a pair of parallel, hollow needles on the fastener dispensing device is linearly driven through the packaging on opposite sides of the item (i.e., with the item positioned between the needles).
  • a feed mechanism then advances each rail of the supply ladder stock into axial alignment behind the longitudinal bore defined by a corresponding hollow needle.
  • a severing mechanism severs each rail at the approximate midpoint between the two lowermost cross-links, thereby separating an individual fastener from the remainder of the ladder stock.
  • an ejection mechanism ejects the cross-bars of the separated fastener through the bores of the pair of hollowed needles and, in turn, through the packaging previously penetrated by the needles.
  • each cross-bar is twisted into a substantially parallel relationship relative to the outer portions of the filament in order to allow for its penetration through the relatively small hole formed in the packaging by its corresponding needle.
  • the resilient construction of the plastic fastener causes each cross-bar to return to its original perpendicular orientation relative to the filament. Accordingly, upon completion of the fastener dispensing process, the inner surface of each generally cylindrical cross-bar lies flat against one surface of the packaging along a generally linear region of contact. At the same time, the majority of the stretchable filament extends tightly across the item on the opposite side of the packaging, thereby retaining the item to the packaging in a relatively secure fashion.
  • plastic fasteners have relatively high elongation properties. Accordingly, each plastic fastener will increase in length, or strain, upon the application of a tensile force thereto. As a result, the elasticity of plastic fasteners can compromise article security. Most notably, an unscrupulous consumer can stretch the fastener to the extent necessary that the article can be separated from its associated packaging.
  • fastening devices with relatively low elongation properties have been increasingly utilized in packaging applications, particularly when article security is of critical importance.
  • cable ties also commonly known as bundling ties and harnessing devices, are commonly utilized in packaging applications to secure an article of commerce to its respective packaging. Once reliably secured to its associated packaging, the article is typically rendered less susceptible to theft or other forms of tampering than packaging that relies upon the use of elastic fasteners.
  • One type of cable tie which is well known and commonly used in the art comprises an elongated strap that is secured, at one of its ends, to an apertured head.
  • the free end of the elongated strap is typically shaped to define a tail of narrowed width to facilitate insertion through the apertured head.
  • a plurality of serrations, or teeth is formed along one surface of the elongated strap along the majority of its length.
  • an internal pawl, or locking tang is disposed within the apertured head and is adapted to sequentially engage the serrations on the strap.
  • a cable tie of the type as described above is commonly used in the following manner to secure an article of commerce (e.g. a handheld tool or toy) to its associated packaging (e.g. a generally planar display card).
  • the article is disposed in its desired position against the front surface of the desired packaging.
  • a pair of narrow slots, each having the approximate dimensions of the strap in transverse cross-section, is preferably preformed or subsequently punched into the packaging on opposite sides of the article in close proximity thereto.
  • the cable tie is then formed into a closed loop by inserting the free end of the serrated strap through the apertured head.
  • the free end of the serrated strap is advanced through the apertured head until the strap cinches tightly across the article, the internal pawl lockably engaging the serrations of the strap to prevent withdrawal, or backing out, of the strap from the apertured head.
  • the engagement of the internal pawl onto the serrated strap secures the cinched cable tie in its closed loop configuration and thereby retains the article firmly against the front surface of the packaging.

  • a method for securing together first and second objects with a band derived from a continuous plastic film, the band having first and second ends, at least one of the first and second objects having a pair of holes comprising the steps of (a) extracting the band from the continuous plastic film and at least partially directing the band through the pair of holes and around the first and second objects, (b) sensing machine readable features in the plastic film to detect plastic film positioning, (c) retaining the first end of the band in an overlapping relationship, (d) tensioning the band around the first and second objects, and (e) bonding the first and second ends together to secure the band in a closed loop configuration.

Additionally, packaging 13 is shaped to define a pair of pre-punched slots 16 - 1 and 16 - 2 , the function of which will become apparent below.
  • device 11 is not limited for use with card-type packaging 13 . Rather, it is to be understood that device 11 could be used with alternative forms of packaging (e.g. a cardboard box or plastic clam shell) without departing from the spirit of the present invention. Accordingly, as defined herein, packaging 13 represents any item of any shape, style or material to which an article of commerce can be secured.
  • banding device 11 is constructed as a compact and unitary machine that is designed to apply a non-elastic plastic band securely around article 12 and packaging 13 in a simple, effective and largely automated fashion.

Additionally, film 18 may be branded or otherwise visibly marked (e.g. with a corporate logo) for marketing purposes. Lastly, film 18 may be provided with a security device (e.g. an embedded radio frequency identification (RFID) chip or the like) to deter theft of article 12 .

  • Active rollers are directly or indirectly driven by a stepper motor (not shown), the operation of which is regulated by an electronic controller (not shown). In turn, activation of the device motor is achieved through control panel 46 provided on the exterior of housing 20 .
  • an externally accessible, depressible lighted power toggle switch coupled with a power input receptacle 43 is provided on side panel 28 of housing 20 and serves to deliver power to the electronic controller for device 11 when a powered input cord (not shown) is attached.
  • the lighted power toggle switch coupled with a power input receptacle 43 on side panel 28 of housing 20 when lit, indicates that power is being delivered to the controller for device 11 .

  • Film guides 33 - 1 and 33 - 2 are a pair of opposing arcuate chutes that serve to facilitate directing film 18 around packaging 13 and article 12 .
  • Each guide 33 is generally arc shaped in transverse cross-section and is dimensioned to fittingly receive and direct band 17 along the appropriate path.
  • Each guide 33 is positioned within interior cavity 31 such that its distal end projects partially through slot 44 in housing 20 . Accordingly, as will be explained further below, the distal end of each guide 33 is dimensioned to fittingly project through a corresponding slot 16 in packaging 13 . In this manner, guides 33 serve to not only hold packaging 13 in position on device 11 but also assist in feeding film 18 through slots 16 in packaging 13 .
  • film guide 33 - 1 is a fixed, or stationary, chute that is located at one end of slot 31 .
  • film guide 33 - 2 is a movable chute that is adapted to slide linearly within slot 44 in both directions relative to fixed film guide 33 - 1 .
  • the spacing between film guides 33 can be adjusted to compensate for variances in the spacing between the pair of pre-punched slots 16 in packaging 13 (i.e. to accommodate a wide range of possible packaging applications).
  • button 34 extracts a defined length of film 18 for use in securing article 12 to packaging 13 .
  • activation includes but is not limited to button 34 . (i.e a foot pedal or other switching device may be used).
  • the ability to extract a section of film 18 to a defined length is achieved using a stepper motor (not shown) coupled with the controller (not shown) for device 11 .
  • the controller for device 11 which is electrically connected to the stepper motor, can calculate the proper length of film 18 to be extracted (e.g. by counting the number of steps the stepper motor has moved radially).

  • the numeric length indicator 35 is coupled to the controller for device 11 and can thereby modify the measured length (e.g. adjusting the panel to read 200 indicates a defined length of extracted film 18 ) and activate the feed mechanism 21 accordingly.
  • the ability to modify the length of film 18 is useful since different packaging applications will typically have different banding requirements. In particular, the length of film 18 is often largely dictated by the shape of article 12 with which it is used.
  • feed mechanism 21 extracts a defined length of film 18 (i.e. band 17 ) that is, in turn, wrapped around article 12 and packaging 13 in a partially overlapping fashion.
  • a clamping mechanism 22 located within interior cavity 31 selectively applies a retaining force onto film 18 when initiated by sensor 42 .
  • sensor 42 is designed to detect machine-readable features incorporated into film 18 at defined intervals.
  • the entire length of film 18 may include markings, such as a sequence of equally-spaced printed lines, which are not detectable by the human eye (e.g. using ultraviolet dyes or inks) but are detectable by sensor 42 .
  • Sensor 42 can utilize markings on film 18 to calculate the proper overlap length of film 18 required for band 17 , as it is inserted into film guide 33 - 1 , to initiate the banding sequence.
  • clamping mechanism 22 includes, inter alia, a backing anvil 37 , a tail clamp head 38 and a holding clamp head 39 that apply forces on film 18 to the extent necessary to retain film 18 in its properly wrapped configuration.
  • Anvil 37 is a planar member that is slidably mounted within interior cavity 31 . As will be described further below, anvil 37 is disposed to selectively project between bottom surface 15 of packaging 13 and film 18 (band 17 ).
  • Tail clamp head 38 is a block-type member that is slidably mounted within interior cavity 31 .
  • Tail clamp head 38 is disposed to selectively protrude towards the underside of backing anvil 37 with film 18 disposed there between. As such, backing anvil 37 and tail clamp head 38 apply pressure onto opposite sides of the tail portion of film 18 so as to define the overlap portion of band 17 .
  • the non-secured end of the film 18 passes through a cutout portion of tail clamp head 38 .
  • the feed mechanism 21 has a tensioning mode as the device motor rotates the active rollers in a direction opposite of the extracted film 18 . This operation enables film 18 to achieve a predetermined loop tension. Accordingly, through the adjustment of an external tension control knob 36 , which is provided in control panel 46 the tension of film 18 can be modified to suit the needs of the intended packaging application. Accordingly, the controller for device 11 , which is electrically connected to the stepper motor, can calculate the proper tension to be applied and then deactivate feed mechanism 21 .
  • Holding clamp head 39 is a block-type member that is slidably mounted within interior cavity 31 .

  • the present invention also contemplates that a shearing mechanism may be used instead of knife blade 41 .
  • knife blade 41 is disposed between heat stake head 40 , tail clamp head 38 and holding clamp head 39 , and is adapted to be selectively driven into contact with film 18 . Based on its location, knife blade 41 severs the enclosed band 17 from the remainder of film 18 .
  • bonding mechanism 23 secures together the overlapping portion (i.e. the free ends) of band 17 .
  • Bonding mechanism 23 comprises a movable heat stake head 40 that is located in interior cavity 31 and regulated by the device controller. As will be explained further below, heat stake head 40 is driven into contact against the overlapping portion of band 17 , with backing anvil 37 providing support for the opposite surface of the overlapping portion. The heat applied from head 40 is of a sufficient temperature to weld together the overlapping segments of band 17 , thereby permanently securing band 17 in its closed loop configuration. Backing anvil 37 then retracts to free the band from the banding device, thereby resulting in the securely packaged product shown in FIG. 2
  • bonding mechanism 23 is not limited to the use of heat to bond together the overlapping segments of film 18 to form band 17 . Rather, it is to be understood that bonding mechanism 23 could bond the overlapping segments of film 18 to form band 17 by alternative means (e.g. through ultrasonic welding) without departing from the spirit of the present invention.

  • rollers 32 - 1 thru 32 - 4 extract a section of film 18 at the desired length, as specified above. It is to be understood that the proper length of the extracted section of film 18 is determined by a stepper motor (not shown), which counts the number of radial steps and the controller of device 11 calculates the proper length of film 18 to extract.
  • the free end 18 - 1 of the extracted section of film 18 is directed by guide 33 - 2 upward through slot 16 - 2 in packaging 13 and is thereby externally accessible.

Additionally, the largely automated operation of device 11 renders the application of band 17 around article 12 and packaging 13 easier to implement than traditional cable ties or other similar types of harnessing devices that are typically installed by hand. Lastly, device 11 is able to direct band 17 through preformed slots 16 in packaging 13 , rather than envelope the entire display card, thereby resulting in a packaged article that is aesthetically pleasing and less susceptible to damage (e.g. bowing or tearing of packaging 15 ).
