Definitions

  • the present invention relates to pouch forming, filling and sealing and more particularly to improved apparatus and methods for forming, filling and sealing stand-up pouches at relatively higher speeds than attainable in currently available systems.
  • a web is unwound and transported to a folding plow wherein the web is folded onto itself.
  • a thermal sealer applies transverse seals or seams in the moving web creating a series or train of pouches with a single fold bottom, sealed edges and an open top.
  • the open pouch train is then introduced to a filler wheel where the pouch sides are opened and the pouch is filled.
  • a top seal is then applied to the pouches, still in train.
  • the filled and sealed pouch train is transported to a rotary cutter wheel where pouches are cut from the pouch train and transported for further packaging in distribution.
  • the pouch forming, filling and sealing apparatus is typically continuous and conducted in line.
  • Stand-up pouches are themselves old. They are configured differently than prior pouches noted above, and there are certain considerations that different configurations require when forming, filling and sealing such pouches.
  • the lower end of the typical stand-up pouch is of a gusseted construction. There is a bottom fold and two parallel reverse folds to create the gusseted bottom.
  • the edge seams or seals extend through two web plies in the upper area of the pouch, and through four web plies in the bottom area of the pouch.
  • such pouches When filled, such pouches have a flat bottom and sides bulged out progressively toward the bottom after filling and product settling; the edges at the edge seams are drawn in so the width of the filled pouch at the expanded pouch -o- bottom is narrower than the width of the filled pouch at the top (when viewed from the side of the pouch).
  • Each pouch seam is sealed at its sides, one side ply to the other, except at the pouch bottom, which is gusseted.
  • the side seam seal must thus extend through four plies at the gusseted bottom.
  • a first longitudinal fold is made in a web, then two reverse folds are formed, one on each side of the first. From each of these two latter reverse folds, the web (which will form the pouch sides) extends upwardly.
  • the bottom area of the web takes on a "W"-shape, i.e. a gusseted shape, in cross-section, with the outside legs of the "W” extending upwardly forming a gusseted bottom structure, then opposed pouch sides.
  • the bottom sides now include four plies (the "W” shape) and these are sealed through the use, of seal openings or holes, previously punched in the inner legs of the "W” shape so that the two outside plies can be sealed together through these holes.
  • the seal facilitating holes are intermittently placed in selected inner plies of the gusseted bottom, typically when the pouch web is intermittently halted prior to folding at a plow.
  • intermittent holing operation is one factor slowing the production to a rate of significantly less than 150 pouches per minute. It is now desirable to produce pouches at web speeds in excess of 500 and preferably 600 web inches per minute, and up to about 1500 pouches per minute or web speeds up to about 4000 web inches per minute. Technology of web handling with attendant require hole punching at these speeds is not believed known prior to this invention.
  • chads are produced. It is important the chads are consistently removed and do not reside between the web folds as to contaminate the pouches to be formed. Increased speeds of continuous operation exacerbate the fugitive chad problems.
  • the effective sealing is typically accomplished by an intermittent sealing operation, not so hot as to bum through the two-ply seam, and not so cold as to ineffectively seal the four ply portion of the seam. If the sealing lands are too hot, as may be required for shorter dwell times if faster throughput is attempted, any slower speed, or any temporary stoppage can damage or burn through the side seam seal. And if too cold, at faster speeds or at start-up, the seals may not be well formed and fail.
  • Pouch opening for filling is generally accomplished by sucking the pouch into a recess on the filler wheel, and sucking an outer pouch away therefrom with a belt or vacuum cup, both with fixed suction devices. It is important to consistently open such pouches. Relying on vacuum introduced from fixed positions alone to pull apart sides for pouch opening may not provide the consistent opening desired for the stand-up pouch configuration.
  • a process similar to that described above for typical pouches other than stand-up pouches is typically utilized with three major exceptions.
  • an intermittent web hole puncher for punching gusset area holes to facilitate side seam sealing is usually situated upstream of the plow.
  • a revised plow is utilized to form the three bottom folds producing the gusset structure on the web forming the pouch bottoms.
  • the sealer must be modified to seal seams of varied plies, typically requiring an intermittent stoppage of the pouches while the seams are sealed.
  • the invention contemplates improvements in producing stand-up pouches by continuously punching sealing holes through application of unique web handling processes in the hole punching area, continuously forming seals to define pouch seams along sides thereof, and across pouch bottom gussets, and continuously and positively opening the moving pouches.
  • pouches formed according to the invention herein include the seal enhancing holes in the pouch gusset bottom structure, such holes are provided in predetermined locations in the web prior to folding; and on the fly as the web is continuously transported past a continuous hole cutting station.
  • a structure comprises a hole cutter capable of cutting holes in the web at the web speeds indicated in excess of about 500 to 600 web inches per minute and up to at least about 4000 web inches per minute without requiring intermittent stoppages of the web.
  • Such a hole cutter is operably disposed adjacent the web path just upstream of the gusset forming plow, and is associated with web edge guides, web tension and web registration processes to enable the speeds desired.
  • an improved chad removal system is provided by having multiple chad removal stages to insure the positive and consistent capture of chads away from the pouch interior.
  • hole cutting is eliminated in favor of using an "on demand" adhesive at the gusset area, such as heat, ultrasonic, radio frequency or other forms of activatible adhesive, pre-applied or pre-printed on the web.
  • an "on demand" adhesive such as heat, ultrasonic, radio frequency or other forms of activatible adhesive, pre-applied or pre-printed on the web.
  • a sealer is now provided which can effectively place consistently sealed seams in the multiple ply, gusseted stand-up pouches in a continuous mode. Tins is accomplished preferably through the use of thick film heater technology.
  • One such sealer is disclosed in U.S. Patent Application Serial No. 09/704,686 filed November 3, 2000 and entitled “Sealing System for Forming Thermal Seals and Method of Operation Thereof," which application is expressly incorporated herein by reference. That system permits continuous, in-line sealing of pouches with transverse seals along gusset sections that are four pouch web layers thick in the gusseted bottom area and are two pouch layers thick along the rest of the seam.
  • the heating differentials provided in the above application produce a differential sealing effect sufficient to efficiently seal the entire multiple-ply pouch edge seam in a continuous, high speed operation with no need to stop the web.
  • the invention contemplates preheating thicker webs of thickness about .005" or more prior to its introduction to the contact sealer wheel. This facilitates sealing and reduces necessary dwell time on the sealer lands.
  • Apparatus for the preferred pouching opening operation includes a Coanda member, such as a circular cross-section, rod curved in a direction of the pouch path about an opening wheel just prior to the pouch filler wheel.
  • An air guide directs air onto the rod which, by Coanda-Effect, flows around the rod, into the open pouch tops and along the pouch sides positively opening the pouches in the train, just below the curved rod.
  • the pouch train is conveyed through a top sealer of any suitable type and further to a knife, preferably rotary, for cut-off and cartoning.
  • a top sealer of any suitable type and further to a knife, preferably rotary, for cut-off and cartoning.
  • the invention contemplates an adjustable bottom gusset sealer to accommodate a variety of pouch sizes, i.e. depths. This is provided by adjustably mounting a bottom gusset sealing shoe between the side seal lands and adjusting the height of the shoe with respect to the lands to viably seal the gusset bottoms of a variety of different sized stand-up pouches.

See Fig. 2A. These holes allow the heat seals to penetrate all four layers of the gusseted bottom structure of the side seams at the pouch bottom.
  • One hole puncher at station 16 capable of continuously forming holes 33, 34 in the web is the continuously operable hole cutter Model PHP- 2001 D/30 manufactured by Mali Plastics Limited of Tel Aviv, Israel. Another suitable hole cutter, Model Jones 1-200, is available from Chicago Cutting Die Company of Chicago, Illinois. Any suitable rotary die can be used, however, according to the invention, hole punching accuracy and chad removal at desired speeds are provided by apparatus and process as will be described.

  • These holes of any suitable size, then facilitate the bottom gusset sealing, but must be accurately placed relative to the web. The web registration discussed above provides this function at the speeds indicated.
  • Web 11 is drawn past a gusset forming plow 18 to form the bottom W- shaped fold shown in Fig. 2 A.
  • Plow 18 comprises a frame 39, first fold plow member 41 and center fold plow member 43. As the continuously moving web is drawn past member 41, it defines folds 44, 45. Member 43 defines center fold 46.

  • Preheating is particularly useful with webs for stand-up pouches in web thicknesses of about .005" and greater. It may be used but is not required in thinner webs of about .002" to about .004".

  • the lands 55 can be heated by such heaters applied thereto, or heating elements can be applied to the land faces, in differing heat producing densities to provide sealing.
  • Such a sealer provides adequate heat for sealing in precisely the required areas, yet it is unnecessary to heat a large land mass which may be slow to reach operating temperature upon start up, or too slow to release heat on shut-down. Either circumstance produces ruined seals or bum-through and resulting in waste and restart problems. Moreover, more heat can be applied to the web 19 in exactly the areas requiring it at the gusset fold and less heat in the two-ply area, while yet maintaining web speed in excess of 500 and preferably 600 web inches per minute, for example, through the sealer. On shut-down, heat is quickly dissipated due to low heated land mass, and on start-up, operating temperatures are quickly retained for the same reason, reducing waste.
