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.

- banding device 11 is specifically designed to apply a non-elastic plastic band securely around an article of commerce and its corresponding packaging in a simple, effective and largely automated fashion.
- article of commerce 12 represents any product that is typically secured to packaging as part of its transport and/or display for sale.
- article 12 may be in the form of a conventional retail article, such as a handheld tool, toy or the like.
- Packaging 13 is represented herein as a display, or line card constructed out of, but not limited to, a thick, paper-based material, such as paperboard, chipboard, cardboard or the like. As can be seen, packaging 13 has a generally planar construction with a substantially flat top surface 14 and a substantially flat bottom surface 15 . 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.
- banding device 11 is adapted to receive a continuous supply of a non-elastic plastic film 18 , wrap a separable segment, or band, 17 of film 18 around commercial article 12 and packaging 13 , apply tension with film 18 , and weld together the free ends of band 17 to form a closed-loop. Due to its low elongation properties and welded form of connection, band 17 serves to retain article 12 to packaging 13 in a secure and reliable fashion, which is highly desirable.
- Film 18 is preferably in the form of any thin film plastic material with relatively low elongation properties. As referenced briefly above, film 18 is preferably provided as a continuous web which is wound onto an enlarged rotatable reel, or spool, 19 for ease of storage and subsequent usage by device 11 .
- film 18 is preferably dependent upon the designated packaging application. As an example, film 18 may be clear or colored to provide a particular aesthetical effect. 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 .
- RFID radio frequency identification
- device 11 includes an outer housing 20 adapted to receive packaging 13 and article 12 , a feed mechanism 21 for advancing a segment of film 18 , a sensor 42 for detecting that film 18 is in place to begin the banding sequence, a clamping mechanism 22 for retaining the overlapping portion of band 17 in place, a tensioning mode in mechanism 21 for controlling the loop tension in band 17 , a bonding mechanism 23 for securing together the overlapping portion of band 17 , and a severing mechanism 24 for separating band 17 from the remainder of film 18 .
- a single band 17 wraps article 12 securely to packaging 13 through slots 16 - 1 and 16 - 2 of packaging 13 , as shown in FIG. 2 .
- housing 20 is represented herein as a rectangular, box-shaped enclosure that includes a front panel 25 , a rear panel 26 , a left side panel 27 , a right side panel 28 , a top panel 29 and a bottom panel 30 that together define a substantially enclosed interior cavity 31 into which the majority of the components of device 11 are disposed.
- top panel 29 is shaped to define a narrow lateral slot 44 which provides access to interior cavity 31 .
- reel 19 of film 18 may be disposed outside of housing 20 and fed into interior cavity 31 for banding through a corresponding opening (e.g. in side panel 28 ), as represented in FIG. 1 .
- housing 20 may be dimensioned to receive reel 19 of film 18 within interior cavity 31 .
- device 11 includes a feed mechanism 21 disposed within interior cavity 31 of housing 20 that advances a segment of film.
- Feed mechanism 21 includes a series of rollers 32 - 1 thru 32 - 4 that feed film 18 along a specified path.
- Film guide 33 - 2 directs film 18 through slot 16 - 2 of packaging 13 .
- Film 18 is placed around article 12 and directed through slot 16 - 1 of packaging 13 via film guide 33 - 1 .
- a stepper motor (not shown) is used for regulating the tautness of film 18 during the tensioning mode of feed mechanism 21 .
- Feed mechanism 21 includes both active, or drive, rollers and passive, or pinch, rollers 32 - 1 thru 32 - 4 .
- 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 .
- an externally accessible, depressible film advance button 34 is provided in control panel 46 and is in electrical connection with the electronic controller for device 11 .
- the electronic controller Upon depression of button 34 , the electronic controller delivers power to the motor, which in turn activates feed mechanism 21 to the extent that a defined length of film 18 is automatically delivered for use in securing article 12 to packaging 13 , as will be explained further below.
- 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 length of the extracted portion of film 18 (i.e. the portion of film 18 to ultimately serve as band 17 ) can be varied by the user through manual adjustment of a numeric length indicator 35 provided in control panel 46 of housing 20 .
- 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 .
- holding clamp head 39 is disposed to selectively protrude towards the underside of backing anvil 37 with film 18 disposed there between. As such, backing anvil 37 and holding clamp head 39 apply pressure onto opposite sides of the tail portion of film 18 so as to secure its shape in a closed loop configuration.
- Severing mechanism 24 includes a movable knife blade 41 that is located in interior cavity 31 and regulated by the device controller.
- 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.
- banding device 11 can be used in the following manner to apply non-elastic plastic band 17 securely around article of commerce 12 and packaging 13 in a simple, effective, and largely automated fashion.
- packaging 13 is disposed on housing 20 such that arcuate guides 33 - 1 and 33 - 2 fittingly protrude through corresponding slots 16 - 1 and 16 - 2 , respectively, as shown in FIG. 3( a ) .
- movable guide 33 - 2 can be displaced within slot 44 to accommodate the particular width between slots 16 - 1 and 16 - 2 .
- bottom surface 15 of packaging 13 lies generally flat against top panel 29 of housing 20 .
- the fitted relationship between guides 33 and slots 16 retain packaging 13 fixedly in place on housing 20 .
- article 12 With packaging 13 mounted on housing 20 in the manner set forth above, article 12 is disposed on top surface 14 of packaging 13 between slots 16 - 1 and 16 - 2 . Any fine adjustment of the position of article 12 relative to packaging 13 is then undertaken until the items are disposed in their desired relationship for packaging.
- 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.
- the operator then pulls a portion of the extracted section across article 12 and, in turn, manually inserts free end 18 - 1 through slot 16 - 1 using guide 33 - 1 , as shown in FIG. 3( c ) .
- Device 11 detects the insertion of free end 18 - 1 back into interior cavity 31 by sensor 42 .
- Sensor 42 is designed to detect machine-readable features incorporated into film 18 at defined intervals.
- Film 18 includes markings, such as a sequence of equally-spaced printed lines (e.g. spacing may range, between 0.5 mm and 50.0 mm), 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, as it is inserted into film guide 33 - 1 . When the proper overlap length of film 18 is detected by sensor 42 , the banding sequence is initiated. As seen in FIG.
- tail clamp head 38 of clamping mechanism 22 is displaced inward by the device motor upon activation and urges free end 18 - 1 of film 18 against the underside of backing anvil 37 .
- the extracted section i.e. film 18
- the device motor rotates the active rollers in feed mechanism 21 in a direction opposite of the extracted film 18 operation enabling film 18 to achieve a predetermined loop tension as set by tension control knob 36 .
- knife blade 41 of severing mechanism 24 is driven upward by the device motor sliding along tail clamp head 38 with suitable force to sever band 17 from the remainder of film 18 , as represented in FIG. 3( f ) .
- knife blade 41 positioned to sever film 17 in the manner set forth above, it is to be understood that no excess or unused film 18 (i.e. scrap) is produced by device 11 , thereby maximizing the overall efficiency and cost-effectiveness of device 11 .
- heat stake head 40 of heat stake mechanism 23 is driven upward by the device motor towards backing anvil 37 , as represented in FIG. 3( g ) .
- the heat applied from heat stake head 40 is imparted onto the overlapping portion of band 17 and is of a sufficient temperature to permanently weld together the two overlapping segments.
- the heat stake head 40 may contain one of various patterns or combinations thereof, but is not limited to, the patterns seen in FIG. 4 a - e to direct heat to band 17 .
- an individual, non-elastic band 17 is permanently retained in a closed loop configuration around article 12 and packaging 13 , as shown in FIG. 2 .
- ends 17 - 1 and 17 - 2 overlap one another and are permanently bonded together to securely retain band 17 in its closed loop configuration.
- article 12 and packaging 13 can be simply lifted off of housing 20 .
- band 17 serves to retain article 12 securely to packaging 13 with greater force than a traditional elastic-type fastener. 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 ).

Abstract
A device for applying a non-elastic plastic band securely around an article of commerce and its associated packaging includes a substantially automated feed mechanism for extracting the band from a continuous film at a modifiable length and tension. The feed mechanism includes a pair of arcuate guides that assist in directing the band through a first hole in the packaging, across the article, and through a second hole in the packaging so the ends of the band are disposed on the same side of the packaging. A sensor uses machine readable features within the film to detect film positioning within the device. A clamping device retains the ends of the band together in an overlapping relationship. The trailing end of the band is separated from the remainder of the continuous film by a severing mechanism. Thereafter, the ends of the band are then permanently bonded together by a thermal bonding mechanism, thereby securing the band in its closed loop configuration around the article and its packaging.
Description

- The present invention relates generally to the retail industry and, more particularly, to devices for securing an article of commerce to its respective packaging.
- In the retail industry, 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.
- For instance, plastic fasteners are often used to secure an article to its respective packaging. In 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. One type of 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.
- Automated plastic fastener dispensing devices, or machines, are well known in the art and are commonly used to dispense individual plastic fasteners from a reel of ladder-type fastener stock by severing the side rails at the approximate midpoint between successive cross-links. For example, in U.S. Pat. No. 8,413,866 to W. J. Cooper et al., the disclosure of which is incorporated herein by reference, there is disclosed one well known type of plastic fastener dispensing device that is presently manufactured and sold by Avery Dennison Retail Information Services LLC, through its Fastener Division located in Fitchburg, Mass. known as the ST9500® fastener system.
- In use, a fastener dispensing device of the type as described above can be used to secure an article to its corresponding packaging. Specifically, with the article disposed against the 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. With each rail disposed as such, 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. Having separated an individual fastener from 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.
- During the fastener ejection process, 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. Once each cross-bar passes through the hole in the packaging, 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.
- The use of plastic fasteners to secure an article of commerce to its respective packaging has been found to suffer from a notable shortcoming. Specifically, as referenced above, 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.
- In response thereto, fastening devices with relatively low elongation properties have been increasingly utilized in packaging applications, particularly when article security is of critical importance. For instance, 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. Additionally, 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). Specifically, 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. With the head of the cable tie positioned behind the rear surface of packaging, the free end of the strap is inserted forward through one of the slots, wrapped transversely across the article, and inserted rearward through the other of the slots.
- The cable tie is then formed into a closed loop by inserting the free end of the serrated strap through the apertured head. With the cable tie formed into a closed loop, 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. In this manner, 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.
- Although useful and reliable in securing an article of commerce to its packaging, the use of cable ties in packaging applications has been found to suffer from a notable drawback. Specifically, securing an article to its packaging using cable ties is typically accomplished in a manual fashion, by forming each tie, by hand, into a closed loop. Additionally, any excess strap (i.e. the portion of the strap which does not form the closed loop) is often manually trimmed for aesthetic purposes and/or to ensure that the loose, free end of the strap does not cause any inadvertent damage to the article or its packaging. As can be appreciated, the aforementioned manual steps render the overall packaging process time-consuming, labor-intensive, and expensive to implement, which is highly undesirable.
- It is an object of the present invention to provide a new and improved band for securing an article of commerce to its corresponding packaging.
- It is another object of the present invention to provide a band as described above that has relatively low elongation properties and is therefore less susceptible to tampering.
- It is yet another object of the present invention to provide a band that is clear and visually unobtrusive.
- It is another object of the present invention to provide a band that contains graphics conveying specific information such as brand logos, trademarks, trade dress.
- It is yet another object of the present invention to provide a band that contains radio frequency identification (RFID) technology.
- It is yet another object of the present invention to provide a new and improved banding device for applying the band as described above to the article and its corresponding packaging.
- It is still another object of the present invention to provide a banding device as described above that applies the band to the article and its corresponding packaging in a simple, effective and largely automated fashion.
- It is yet still another object of the present invention to provide a banding device as described above that has a limited number of parts, is easy to use and is inexpensive to manufacture.
- Accordingly, as a feature of the present invention, there is provided a banding device for securing together first and second objects with a band derived from a continuous plastic film, the band having first and second ends, the device comprising (a) a feed mechanism for extracting the band from the continuous plastic film and at least partially directing the band around the first and second objects, (b) a sensor for detecting machine readable features in the plastic film, (c) a clamping mechanism for retaining the first end of the band in an overlapping relationship, (d) a tensioning mode that controls the amount of loop tension in the band around the first and second objects, and (e) a bonding mechanism for bonding the first and second ends together to secure the band in a closed loop configuration.
- As another feature of the present invention, there is provided 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, the method 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.
- Various other features and advantages will appear from the description to follow. In the description, reference is made to the accompanying drawings which form a part thereof, and in which is shown by way of illustration, an embodiment for practicing the invention. The embodiment will be described in sufficient detail to enable those skilled in the art to practice the invention, and it is to be understood that other embodiments may be utilized and that structural changes may be made without departing from the scope of the invention.
- The following detailed description is therefore, not to be taken in a limiting sense, and the scope of the present invention is best defined by the appended claims.

FIGS. 4(a)-(e) are various shapes, patterns or geometries that can assist in directing heat from a heat stake head to overlapping ends of a closed loop band. - Referring now to
FIG. 1 , there is shown a banding device constructed according to the teachings of the present invention, the banding device being identified generally byreference numeral 11. As will be explained in detail below, bandingdevice 11 is specifically designed to apply a non-elastic plastic band securely around an article of commerce and its corresponding packaging in a simple, effective and largely automated fashion. - In the description that follows,
device 11 is shown securing an article ofcommerce 12 to its associatedpackaging 13. As defined herein, article ofcommerce 12 represents any product that is typically secured to packaging as part of its transport and/or display for sale. For instance,article 12 may be in the form of a conventional retail article, such as a handheld tool, toy or the like. -
Packaging 13 is represented herein as a display, or line card constructed out of, but not limited to, a thick, paper-based material, such as paperboard, chipboard, cardboard or the like. As can be seen, packaging 13 has a generally planar construction with a substantially flattop surface 14 and a substantiallyflat bottom surface 15. 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. - It should be noted that
device 11 is not limited for use with card-type packaging 13. Rather, it is to be understood thatdevice 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. - Referring now to
FIGS. 1 and 2 , bandingdevice 11 is constructed as a compact and unitary machine that is designed to apply a non-elastic plastic band securely aroundarticle 12 andpackaging 13 in a simple, effective and largely automated fashion. As will be described in detail below, bandingdevice 11 is adapted to receive a continuous supply of anon-elastic plastic film 18, wrap a separable segment, or band, 17 offilm 18 aroundcommercial article 12 andpackaging 13, apply tension withfilm 18, and weld together the free ends ofband 17 to form a closed-loop. Due to its low elongation properties and welded form of connection,band 17 serves to retainarticle 12 topackaging 13 in a secure and reliable fashion, which is highly desirable. -
Film 18 is preferably in the form of any thin film plastic material with relatively low elongation properties. As referenced briefly above,film 18 is preferably provided as a continuous web which is wound onto an enlarged rotatable reel, or spool, 19 for ease of storage and subsequent usage bydevice 11. - The particular design and construction of
film 18 is preferably dependent upon the designated packaging application. As an example,film 18 may be clear or colored to provide a particular aesthetical effect. 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 ofarticle 12. - Referring to
FIG. 3(a) ,device 11 includes anouter housing 20 adapted to receivepackaging 13 andarticle 12, afeed mechanism 21 for advancing a segment offilm 18, asensor 42 for detecting thatfilm 18 is in place to begin the banding sequence, aclamping mechanism 22 for retaining the overlapping portion ofband 17 in place, a tensioning mode inmechanism 21 for controlling the loop tension inband 17, abonding mechanism 23 for securing together the overlapping portion ofband 17, and asevering mechanism 24 for separatingband 17 from the remainder offilm 18. As a product of the operation ofdevice 11, asingle band 17wraps article 12 securely topackaging 13 through slots 16-1 and 16-2 ofpackaging 13, as shown inFIG. 2 . - As seen in
FIG. 1 ,housing 20 is represented herein as a rectangular, box-shaped enclosure that includes a front panel 25, a rear panel 26, a left side panel 27, a right side panel 28, a top panel 29 and a bottom panel 30 that together define a substantially enclosedinterior cavity 31 into which the majority of the components ofdevice 11 are disposed. As can be seen, top panel 29 is shaped to define a narrowlateral slot 44 which provides access tointerior cavity 31. - It should be noted that
reel 19 offilm 18 may be disposed outside ofhousing 20 and fed intointerior cavity 31 for banding through a corresponding opening (e.g. in side panel 28), as represented inFIG. 1 . Alternatively,housing 20 may be dimensioned to receivereel 19 offilm 18 withininterior cavity 31. - As seen most clearly in
FIG. 3(a) ,device 11 includes afeed mechanism 21 disposed withininterior cavity 31 ofhousing 20 that advances a segment of film.Feed mechanism 21 includes a series of rollers 32-1 thru 32-4 that feedfilm 18 along a specified path. Film guide 33-2 directsfilm 18 through slot 16-2 ofpackaging 13.Film 18 is placed aroundarticle 12 and directed through slot 16-1 ofpackaging 13 via film guide 33-1. A stepper motor (not shown) is used for regulating the tautness offilm 18 during the tensioning mode offeed mechanism 21. -
Feed mechanism 21 includes both active, or drive, rollers and passive, or pinch, rollers 32-1 thru 32-4. 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 throughcontrol panel 46 provided on the exterior ofhousing 20. - Specifically, as seen most clearly in
FIG. 1 , an externally accessible, depressible lighted power toggle switch coupled with apower input receptacle 43 is provided on side panel 28 ofhousing 20 and serves to deliver power to the electronic controller fordevice 11 when a powered input cord (not shown) is attached. The lighted power toggle switch coupled with apower input receptacle 43 on side panel 28 ofhousing 20, when lit, indicates that power is being delivered to the controller fordevice 11. - Additionally, an externally accessible, depressible
film advance button 34 is provided incontrol panel 46 and is in electrical connection with the electronic controller fordevice 11. Upon depression ofbutton 34, the electronic controller delivers power to the motor, which in turn activatesfeed mechanism 21 to the extent that a defined length offilm 18 is automatically delivered for use in securingarticle 12 topackaging 13, as will be explained further below. - Film guides 33-1 and 33-2 are a pair of opposing arcuate chutes that serve to facilitate directing
film 18 aroundpackaging 13 andarticle 12. Each guide 33 is generally arc shaped in transverse cross-section and is dimensioned to fittingly receive anddirect band 17 along the appropriate path. - Each guide 33 is positioned within
interior cavity 31 such that its distal end projects partially throughslot 44 inhousing 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 inpackaging 13. In this manner, guides 33 serve to not only holdpackaging 13 in position ondevice 11 but also assist in feedingfilm 18 through slots 16 inpackaging 13. - Preferably, film guide 33-1 is a fixed, or stationary, chute that is located at one end of
slot 31. By contrast, film guide 33-2 is a movable chute that is adapted to slide linearly withinslot 44 in both directions relative to fixed film guide 33-1. In this manner, 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). - As referenced above, activation of
button 34 extracts a defined length offilm 18 for use in securingarticle 12 topackaging 13. Note that activation includes but is not limited tobutton 34. (i.e a foot pedal or other switching device may be used). The ability to extract a section offilm 18 to a defined length is achieved using a stepper motor (not shown) coupled with the controller (not shown) fordevice 11. Accordingly, the controller fordevice 11, which is electrically connected to the stepper motor, can calculate the proper length offilm 18 to be extracted (e.g. by counting the number of steps the stepper motor has moved radially). - The length of the extracted portion of film 18 (i.e. the portion of
film 18 to ultimately serve as band 17) can be varied by the user through manual adjustment of anumeric length indicator 35 provided incontrol panel 46 ofhousing 20. As can be appreciated, thenumeric length indicator 35 is coupled to the controller fordevice 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 thefeed mechanism 21 accordingly. The ability to modify the length offilm 18 is useful since different packaging applications will typically have different banding requirements. In particular, the length offilm 18 is often largely dictated by the shape ofarticle 12 with which it is used. - As referenced briefly above,
feed mechanism 21 extracts a defined length of film 18 (i.e. band 17) that is, in turn, wrapped aroundarticle 12 andpackaging 13 in a partially overlapping fashion. To maintainfilm 18 tightly wrapped aroundarticle 12 andpackaging 13, aclamping mechanism 22 located withininterior cavity 31 selectively applies a retaining force ontofilm 18 when initiated bysensor 42. Specifically,sensor 42 is designed to detect machine-readable features incorporated intofilm 18 at defined intervals. For instance, the entire length offilm 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 bysensor 42.Sensor 42 can utilize markings onfilm 18 to calculate the proper overlap length offilm 18 required forband 17, as it is inserted into film guide 33-1, to initiate the banding sequence. - As seen most clearly in
FIG. 3(a) ,clamping mechanism 22 includes, inter alia, abacking anvil 37, atail clamp head 38 and a holdingclamp head 39 that apply forces onfilm 18 to the extent necessary to retainfilm 18 in its properly wrapped configuration.Anvil 37 is a planar member that is slidably mounted withininterior cavity 31. As will be described further below,anvil 37 is disposed to selectively project betweenbottom surface 15 ofpackaging 13 and film 18 (band 17). -
Tail clamp head 38 is a block-type member that is slidably mounted withininterior cavity 31.Tail clamp head 38 is disposed to selectively protrude towards the underside of backinganvil 37 withfilm 18 disposed there between. As such,backing anvil 37 andtail clamp head 38 apply pressure onto opposite sides of the tail portion offilm 18 so as to define the overlap portion ofband 17. - The non-secured end of the
film 18 passes through a cutout portion oftail clamp head 38. Thefeed mechanism 21 has a tensioning mode as the device motor rotates the active rollers in a direction opposite of the extractedfilm 18. This operation enablesfilm 18 to achieve a predetermined loop tension. Accordingly, through the adjustment of an externaltension control knob 36, which is provided incontrol panel 46 the tension offilm 18 can be modified to suit the needs of the intended packaging application. Accordingly, the controller fordevice 11, which is electrically connected to the stepper motor, can calculate the proper tension to be applied and then deactivatefeed mechanism 21. Holdingclamp head 39 is a block-type member that is slidably mounted withininterior cavity 31. Similar totail clamp head 38, holdingclamp head 39 is disposed to selectively protrude towards the underside of backinganvil 37 withfilm 18 disposed there between. As such,backing anvil 37 and holdingclamp head 39 apply pressure onto opposite sides of the tail portion offilm 18 so as to secure its shape in a closed loop configuration. - Severing
mechanism 24 includes amovable knife blade 41 that is located ininterior cavity 31 and regulated by the device controller. The present invention also contemplates that a shearing mechanism may be used instead ofknife blade 41. As will be explained further below,knife blade 41 is disposed betweenheat stake head 40,tail clamp head 38 and holdingclamp head 39, and is adapted to be selectively driven into contact withfilm 18. Based on its location,knife blade 41 severs theenclosed band 17 from the remainder offilm 18. - With
band 17 retained in a closed-loop configuration by clampingmechanism 22,bonding mechanism 23 secures together the overlapping portion (i.e. the free ends) ofband 17.Bonding mechanism 23 comprises a movableheat stake head 40 that is located ininterior 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 ofband 17, with backinganvil 37 providing support for the opposite surface of the overlapping portion. The heat applied fromhead 40 is of a sufficient temperature to weld together the overlapping segments ofband 17, thereby permanently securingband 17 in its closed loop configuration. Backinganvil 37 then retracts to free the band from the banding device, thereby resulting in the securely packaged product shown inFIG. 2 - It should be noted that
bonding mechanism 23 is not limited to the use of heat to bond together the overlapping segments offilm 18 to formband 17. Rather, it is to be understood thatbonding mechanism 23 could bond the overlapping segments offilm 18 to formband 17 by alternative means (e.g. through ultrasonic welding) without departing from the spirit of the present invention. - Referring now to
FIGS. 3(a)-(i) ,banding device 11 can be used in the following manner to applynon-elastic plastic band 17 securely around article ofcommerce 12 andpackaging 13 in a simple, effective, and largely automated fashion. To commence the banding process, packaging 13 is disposed onhousing 20 such that arcuate guides 33-1 and 33-2 fittingly protrude through corresponding slots 16-1 and 16-2, respectively, as shown inFIG. 3(a) . If necessary, movable guide 33-2 can be displaced withinslot 44 to accommodate the particular width between slots 16-1 and 16-2. Once properly mounted,bottom surface 15 ofpackaging 13 lies generally flat against top panel 29 ofhousing 20. The fitted relationship between guides 33 and slots 16retain packaging 13 fixedly in place onhousing 20. - With packaging 13 mounted on
housing 20 in the manner set forth above,article 12 is disposed ontop surface 14 ofpackaging 13 between slots 16-1 and 16-2. Any fine adjustment of the position ofarticle 12 relative topackaging 13 is then undertaken until the items are disposed in their desired relationship for packaging. - The operator then activates
device 11 by depressingrun button 34, with indication of operability being provided by an indicator light which is illuminated onrun button 34. Prior to commencing the band delivery operation, the operator sets the desired length and tension offilm 18 viacontrols resultant band 17 is largely dependent upon the particular packaging application. - To commence the band delivery process, the operator depresses
button 34 which delivers a signal to the device controller. In response thereto, the device controller activates device motor, which rotably drives active rollers infeed mechanism 21. Accordingly, rollers 32-1 thru 32-4 extract a section offilm 18 at the desired length, as specified above. It is to be understood that the proper length of the extracted section offilm 18 is determined by a stepper motor (not shown), which counts the number of radial steps and the controller ofdevice 11 calculates the proper length offilm 18 to extract. - As seen in
FIG. 3(b) , the free end 18-1 of the extracted section offilm 18 is directed by guide 33-2 upward through slot 16-2 inpackaging 13 and is thereby externally accessible. The operator then pulls a portion of the extracted section acrossarticle 12 and, in turn, manually inserts free end 18-1 through slot 16-1 using guide 33-1, as shown inFIG. 3(c) . -
Device 11 detects the insertion of free end 18-1 back intointerior cavity 31 bysensor 42.Sensor 42 is designed to detect machine-readable features incorporated intofilm 18 at defined intervals.Film 18 includes markings, such as a sequence of equally-spaced printed lines (e.g. spacing may range, between 0.5 mm and 50.0 mm), which are not detectable by the human eye (e.g. using ultraviolet dyes or inks) but are detectable bysensor 42.Sensor 42 can utilize markings onfilm 18 to calculate the proper overlap length offilm 18 required, as it is inserted into film guide 33-1. When the proper overlap length offilm 18 is detected bysensor 42, the banding sequence is initiated. As seen inFIG. 3(d) ,tail clamp head 38 ofclamping mechanism 22 is displaced inward by the device motor upon activation and urges free end 18-1 offilm 18 against the underside of backinganvil 37. In this capacity, the extracted section (i.e. film 18) is formed into a generally closed loop, withtail clamp head 38 directing free end 18-1 inside the trailing segment offilm 18 in an overlapping fashion. Once thetail clamp head 38 engages the free end 18-1 offilm 18 againstbacking anvil 37, the device motor rotates the active rollers infeed mechanism 21 in a direction opposite of the extractedfilm 18operation enabling film 18 to achieve a predetermined loop tension as set bytension control knob 36. - With
film 18 at a predetermined loop tension as set bytension control knob 36, holdingclamp head 39 is displaced, commencing formation ofband 17. Holdingclamp head 39 ofclamping mechanism 22 urges trailing end 17-2 ofband 17 against tail end 17-1 and presses both the overlapping trailing end 17-2 and the tail end 17-1 against the underside of backinganvil 37, as seen inFIG. 3(e) . In this capacity, aband 17 is formed. - Upon completion of the holding clamp sequence,
knife blade 41 of severingmechanism 24 is driven upward by the device motor sliding alongtail clamp head 38 with suitable force to severband 17 from the remainder offilm 18, as represented inFIG. 3(f) . Withknife blade 41 positioned to severfilm 17 in the manner set forth above, it is to be understood that no excess or unused film 18 (i.e. scrap) is produced bydevice 11, thereby maximizing the overall efficiency and cost-effectiveness ofdevice 11. - Thereafter,
heat stake head 40 ofheat stake mechanism 23 is driven upward by the device motor towardsbacking anvil 37, as represented inFIG. 3(g) . The heat applied fromheat stake head 40 is imparted onto the overlapping portion ofband 17 and is of a sufficient temperature to permanently weld together the two overlapping segments. Theheat stake head 40 may contain one of various patterns or combinations thereof, but is not limited to, the patterns seen inFIG. 4a-e to direct heat toband 17. - As shown in
FIG. 3(h) , immediately after the aforementioned film severing step,knife blade 41, holdingclamp head 39,tail clamp head 38 andheat stake head 40 retract back toward bottom panel 30 to its original starting position. During this motion, as shown inFIG. 3(i) ,anvil 37 retracts toward front panel 25, allowingcommercial article 12,packaging 13 andband 17 to release fromdevice 11. After releasingcommercial article 12,packaging 13 andband 17 fromdevice 11,anvil 37 returns to the starting position. In this manner,device 11 is prepared to repeat the above-described banding process as often as needed. - As a result of the aforementioned banding process, an individual,
non-elastic band 17 is permanently retained in a closed loop configuration aroundarticle 12 andpackaging 13, as shown inFIG. 2 . As can be seen, ends 17-1 and 17-2 overlap one another and are permanently bonded together to securely retainband 17 in its closed loop configuration. Once banded together,article 12 andpackaging 13 can be simply lifted off ofhousing 20. - As a feature of the present invention, the non-elastic nature of
band 17 serves to retainarticle 12 securely topackaging 13 with greater force than a traditional elastic-type fastener. Additionally, the largely automated operation ofdevice 11 renders the application ofband 17 aroundarticle 12 andpackaging 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 directband 17 through preformed slots 16 inpackaging 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). - The embodiment shown above is intended to be merely exemplary and those skilled in the art shall be able to make numerous variations and modifications to it without departing from the spirit of the present invention. All such variations and modifications are intended to be within the scope of the present invention as defined in the appended claims.
