Definitions

  • the present invention relates to packaging machines which deliver product to the interior of tubular bag material, and form discrete packages therefrom.
  • U.S. Patent No. 4,663,917 Described in U.S. Patent No. 4,663,917 is a rotary packaging machine which receives tubular bag material and forms discrete packages therefrom, with material being packaged located therein.
  • the tubular bag material is formed from a ribbon of material past about a former, with the longitudinal edges being joined to form the tubular bag material.
  • the bag material is propelled through the packaging machine by rollers or belts, such as the drive system of U.S. Patent No. 4,910,943.
  • a packaging machine through which tubular bag material passes and to which products to be packaged is delivered, with the bag material being transversely severed to form discrete packages, said machine including a pair of bag engaging members located on opposite sides of the bag material which engage the tubular bag material to cause transverse contraction thereof, the transverse contraction causing acceleration of an end portion of the bag material, which is to form a next bag, to aid in settling the product, and a drive mechanism to cause reciprocation of the bag engaging members to cause the transverse contraction to be intermittent.
  • the packaging machine 10 includes a former 11 which receives a strip of packaging film to form the film into tubular bag material 12. The edges of the film are joined, with the film being pulled through the packaging machine 10 by a pair of driven belts 13. The bag material 12 passes vertically downward through the machine 10.
  • the packaging machine 10 would include a pair of rotatably driven arms 17, the ends of which are provided with sealing jaws 18, and a blade to severe the bag being formed from the tubular bag material 12. There may be stripper bars associated with the jaws 18 to strip the bag material 12. Closer bars may also be used.
  • a pair of bag engaging members 19 located on opposite sides of the bag material 12 which are caused to reciprocate transversely of the tubular material 12 to cause intermittent transverse contraction thereof. More particularly, the members 19 are caused to reciprocate linearly in unison in opposite directions generally normal to the longitudinal axis 20 of the tubular bag material 12. This transverse contraction of the bag material 12 causes the end portion 16 to vertically accelerate (upwardly) and then to downwardly accelerate upon retraction of the members 19 to aid in settling the product 15. This takes place prior to the jaws 18 engaging the material 12. Typically, the bag engaging members 19 would reciprocate horizontally between three and six times per second, preferably four times per second.
  • the bag engaging members 19 are attached to rods 21 of pneumatic rams (drive mechanism) 22.
  • the rams 22 would have a cylinder body 23 attached to the frame of the packaging machine 10. Air under pressure would be delivered intermittently to the rams 22 to cause horizontal linear reciprocation of the members 19.
  • Reciprocation of the bag engaging members 19 is also preferably coordinated with delivery of the product 15 to the interior of the bag material 12 so that the bag engaging members 19 do not inhibit delivery of the product 15 to the end portion 16.
  • a weighing machine would be associated with the packaging machine 10 and would deliver discrete volumes or weights of product 15 to the tubular bag material at the times required.
  • FIGS. 3 and 4 of the accompanying drawings a further preferred form of the present invention is shown.
  • the bag engaging members 24 are attached to arms 25.
  • the arms 25 extend to stepping motors 26 which causes angular oscillation of the arms 25 and therefore angular oscillation (reciprocation) of the members 24 to cause transverse intermittent contraction of the tubular bag material 12.
  • the angular oscillation of the arms 25 is about fixed horizontal parallel axes, generally transverse of the bag material 12 so that the arms 25 move in unison in angular opposite directions.
  • stepping motors 26 may be replaced with rotary cylinders or servo motors.
  • the bag engaging members 19 and 24 contract and then allow the bag material 12 to expand, at least once while each bag is being formed, that is before the jaws 18 prevent movement of the portion 16, and therefor before the bag is formed. This would take place when product 15 is within the length of bag material 12 to form the next bag.
  • the members 19 and 24, as seen in Figures 1 and 3, engage and release the bag material 12 before the jaws 18 engage the bag material 12.
  • the members 19 and 24 would extend and retract at least twice for each bag being formed.
  • the members 19 and 24 rapidly engage and retract with respect to the bag material 12, the movement of the members 19 and 24 being preferably such that the lower portion 16 of the material 12 actually lifts, as seen in Figures 1 and 3.
  • the members 19 and 24 have a component of their direction of movement normal to the bag material 12, that is horizontal.
  • the embodiment of Figures 1 and 2 has the members 19 move only horizontally, while in the embodiment of Figures 3 and 4, the members 24 have a vertical and horizontal component to their direction of movement.
