Abstract

An apparatus for simultaneously separating a portion of a continuous web of film, having a leading edge and a plurality of spaced apart side seals, includes a base, a plurality of blade pairs, and a film guide device. The blade pairs are moveable between an open and closed positions and are mounted to the base and spaced apart a distance corresponding to the side seals in the film. The film guide device includes a guide member that releasable attaches to a portion of the film adjacent the leading edge. The guide members suspends the film between the plurality of blade pairs in the open position to align the plurality of seals on the film with the plurality of spaced apart blade pairs to accurate separate the film into a plurality of pouches upon movement of the blade pairs to the closed position.

First claim

It is claimed:

1. An apparatus for simultaneously separating a portion of a continuous web of film into a plurality of pouches, the film having a leading edge and a plurality of spaced apart seals, said apparatus comprising:
a base;
a plurality of spaced apart blade pairs mounted to said base, each of said blade pairs moveable between an open position and a closed position; and
a film guide device having a guide member that releasable attaches to an exterior surface of a portion of the film adjacent the leading edge, said guide member passes through said plurality of spaced apart blade pairs in said open position to pull the film through said plurality of blade pairs in said open position so as to align the plurality of seals on the film with said plurality of spaced apart blade pairs to separate the film into a plurality of pouches upon movement of said plurality of blade pairs from said open position to said closed position.

2. The apparatus of claim 1 , wherein said film guide device includes a track and said guide member operable to rotate around said track.

3. The apparatus of claim 2 , wherein said guide member is a suction cup device that attaches to the film using a vacuum.

4. The apparatus of claim 3 , wherein said film guide device includes a plurality of guide members, each of said guide members being attached to said track at a predetermined distance apart.

5. The apparatus of claim 4 , wherein said plurality of spaced apart blade pairs includes a plurality of first blade portions and a plurality of second blade portions, each of said plurality of second blade portions corresponding to one of said plurality of first blade portions, and wherein said plurality of first blade portions are fixed to said base member and said plurality of second blade portions are pivotally mounted to said base member along a first pivot axis.

6. The apparatus of claim 5 further comprising a reciprocating mechanism that reciprocatingly pivots said plurality of second blade portions along said first pivot axis between said open position and said closed position.

7. The apparatus of claim 6 , wherein said reciprocating mechanism includes a pair rocker arms, a connection member, and a reciprocating unit, said pair of rocker arms being pivotally attached to said base member along a second pivot axis, said connection member extending between said pair of rocker arms and connected to each of said plurality of second blade portions, said reciprocating unit reciprocatingly pivots said pair of rocker arms about said second pivot axis to drive said plurality of second blade portions between said open position and said closed position.

8. The apparatus of claim 7 , wherein said second pivot axis is parallel with and spaced apart from said first pivot axis.

9. The apparatus of claim 8 , wherein a film driver is positioned on one end of said apparatus, and said film driver having a pair of opposing rollers that receive the film therebeween to drive the film towards said apparatus, and wherein upon exiting the film driver one of said guide members attaches to a portion of the film adjacent the leading edge.

10. The apparatus of claim 9 , wherein a secondary suction device is positioned on an end of said apparatus opposite said film driver, said secondary suction device releasable attaches to the leading edge of the film as one of said guide members rotates and disengages from the leading edge of the film, and wherein said secondary suction devices holds the portion of the film adjacent the leading edge in place to align the plurality of seals with said plurality of spaced apart blade pairs.

11. The apparatus of claim 1 further comprising
a transfer apparatus positioned between said separating apparatus and a multi-pouch fill seal machine, said transferring apparatus having a frame, an elongated member, and a plurality of clips;
said elongated member slidably attached to said frame, said elongated member moveable in a first direction between a first position adjacent said separating apparatus and a second position adjacent said fill-seal machine in a first direction; and
said plurality of clips operable to grip an upper edge of the pouches, each of said plurality of clips being slidably attached to said elongated member in a second direction, said second direction being perpendicular to said first direction, said plurality of clips gripping the upper edge of the pouches as said separation apparatus separates the pouches and transfers the pouches to said fill-seal machine, said plurality of clips spaced apart a first distance when said elongated member is in said first position and said plurality of clips move in said second direction as said elongated member moves from said first position to said second position such that said plurality of clips are spaced apart a second distance when said elongated member is in said second position, said second distance being greater than said first distance.

12. An apparatus for forming a plurality of pouches from a continuous web of film having a leading edge and a plurality of side seals, the pouches having an upper edge, an opposite lower edge, and a pair of side edges extending between the upper top edge and the bottom edge, said apparatus comprising:
a separating apparatus that simultaneously separates a portion of the continuous web of film into the plurality of pouches, the separating apparatus includes a plurality of spaced apart blade pairs moveable between an open position and a closed position;
a film guide device having a guide member that releasably attaches to an exterior surface of a portion of the film adjacent the leading edge, said guide member passes through said plurality of spaced apart blade pairs in said open position to pull the film through said plurality of blade pairs in said open position so as to align the plurality of seals on the film with said plurality of spaced apart blade pairs to separate the film into a plurality of pouches upon movement of said plurality of blade pairs from said open position to said closed position;
a fill-seal machine that fills and seals the plurality of pouches; and
a transfer apparatus positioned between said separating apparatus and said fill-seal machine, said transfer apparatus simultaneously transfers the plurality of pouches separated by said separating apparatus to said fill-seal machine.

13. The apparatus of claim 12 , wherein said transfer apparatus includes:
a frame positioned between said separating apparatus and said fill-seal machine;
an elongated member slidably attached to said frame, said elongated member moveable in a first direction between a first position adjacent said separating apparatus and a second position adjacent said fill-seal machine; and
a plurality of clips for gripping the upper edge of the pouches, each of said plurality of clips being slidably attached to said elongated member in a second direction, said second direction being perpendicular to said first direction, said plurality of clips gripping the upper edge of the pouches as said separation apparatus separates the pouches and transfers the pouches to said fill-seal machine, said plurality of clips spaced apart a first distance when said elongated member is in said first position and said plurality of clips move in said second direction as said elongated member moves from said first position to said second position such that said plurality of clips are spaced apart a second distance when said elongated member is in said second position, said second distance being greater than said first distance.

14. The apparatus of claim 13 , wherein each of said plurality of clips includes a sli
