Definitions

  • the present invention generally relates to an apparatus and method for applying fitments, such as opening and closing devices, onto packages. More particularly, the present invention provides a method and apparatus for high-speed, leakproof application of individual fitments to packages that enable hundreds or even thousands of packages to have fitments attached per hour of operation.
  • the present invention was developed in the context of paperboard packages, aseptic packages sometimes referred to • as "juice boxes” and similar packaging for soups, milk, and other foods and beverages. However, it will be apparent that the present invention will have application to other types of packaging, even packaging for other than food and beverages and for packaging materials other .than paperboard.
  • the apparatus and method of the present invention were developed for applying a small plastic fitment to the previously mentioned packaging for use in opening and reclosing a package. It will be recognized that the present invention would be useful for other than just plastic fitments and other than the particular package fitments described and •shown herein.
  • the means for resealing or reclosing a package to store unused contents consists of folding the paperboard in a particular way to close the package.
  • the '290 patent is incorporated by reference herein. A method and machine were needed to apply the fitments to the packages in an automated, high-speed, manner without damaging the integrity of the package or its contents.
  • the applicator machine of the present invention is a constant motion machine preferably rotating at a set RPM level and capable of applying fitments to several thousand packages per hour.
  • the machine is set up to accommodate a particular size package and is readily changeable to accommodate different sizes.
  • Packages are fed into an infeed section and collected by a star wheel to be transferred into an applicator rotating turret wheel.
  • Fitments are loaded into a feed hopper, sorted in a feed bowl, then oriented and transported to a transfer conveyor. Prior to being placed into the feed hopper, the surface of the fitment that will ultimately be in contact with the package is precoated with an adhesive that at room temperature is firmly bonded to the fitment, but is not capable of bonding to another surface unless reactivated by heat.
  • the fitments having a preapplied adhesive, now travel through a transfer conveyor on the machine and are indexed over a heating station where the preapplied adhesive is reactivated.
  • the fitments are then collected by pick-up devices mounted on the rotating turret and transferred to the packages, where they are individually placed and held in position on the package until fully adhered.
  • the packages with fitments attached are then removed from the rotating turret wheel by a second star wheel and transferred onto an exit conveyor.
  • the applicator machine may be equipped with controls for varying the operating speed.
  • An ejector station may be installed on the exit conveyor to collect any packages that are rejected by the applicator control system.
  • a main drive assembly may be enclosed below the operating deck under the turret wheel.
  • the turret wheel main shaft is driven via a main gear box that may be driven by a variable speed motor.
  • the infeed and outfeed wheels may be gear driven by a main gear mounted on the turret wheel main shaft.
  • the method of the present invention begins by preparing the surface of the fitments that will be in contact with the package, by applying a hot melt glue or other adhesive to the surface, manually or by a specially designed apparatus.
  • the adhesive is then allowed to cure on the surface so that it will not tend to stick to anything but the fitment at room temperature in its deactivated state. In this deactivated state, the adhesive is substantially solidified.
  • the packages are prepared for introduction to the applicator machine.
  • the fitments are transferred from the sorting bowl to a heating station where the adhesive is reactivated. From there, the fitments are transferred to the applicator section and secured to the package by means of the reactivated adhesive.
  • the packages complete with fitments are then ejected from the machine and transferred to secondary packaging equipment
  • the process may also be arranged for applying the adhesive to the fitment and very soon thereafter securing the fitment to the package without the steps of allowing the adhesive to solidify then reactivating it.
  • the adhesive may first be applied to the package and the fitment placed on the adhesive which is already on the package.
  • FIGURE 1 is a flow chart of one embodiment of the process of the present invention.
  • FIGURE 2 is a plan view of the applicator machine of the present invention
  • FIGURE 3 is a side view of the applicator machine of the present invention
  • FIGURE 4 is an enlarged detailed plan view of the turret wheel portion of the applicator machine of the present invention.
  • FIGURE 5 is a section view taken along lines 5-5 of Figure 4;
  • FIGURE 6 is a prospective view of a fitment pick-up device associated with the main turret wheel of the applicator machine of the present invention.
  • FIGURE 7 is a prospective view of a package having a fitment secured thereto by use of the method and apparatus of the present invention
  • FIGURE 8 is a plan view of a package infeed station on the applicator machine of the present invention.
  • FIGURE 9 is a side elevational view of the heating station on the applicator machine of the present invention.
  • FIGURE 10 is a plan view of the fitment conveying mechanism on the applicator machine of the present invention.
  • FIGURE 11 is a section view taken along line 11-11 of Figure 10.
  • the process begins with two separate paths 20,22.
  • the first path ' 20 is concerned with the preparation of the fitments while the second path 22 is concerned with the preparation of the packages. Both paths meet at stage 24 of the process where the fitments are applied to the packages.
  • the process may begin with step 26 where application of an adhesive to the underside of a base portion of each fitment is accomplished.
  • the adhesive may be a hot melt thermoplastic resin or glue, or equivalent, typically used in assembling plastic components to paperboard structures.
  • One preferred adhesive is Findley No. 335-335 which may be purchased from Findley Adhesives, Incorporated, Wauwatosa, Wisconsin.
  • the adhesive is preferably of a type that, once it is allowed to cure, it becomes generally solid to the touch and adheres to the fitment without tending to stick to other surfaces in its solidified state.
  • the fitments having the solidified adhesive thereon may then be loaded 28 into a prefeeder hopper associated with the fitment applicator machine.
  • the fitments may be loaded into the hopper in mass quantities.
  • the fitments move 30 by gravity, or vibration, or otherwise from the hopper into a vibratory bowl.
  • the vibratory bowl may be purchased from Feeder Corporation of America, Melrose Park, Illinois, or equivalent. Loose fitments are collected in the bottom of the vibratory bowl.
