System and Method for Assembly of Packettes Having Closures
A method of automatically manufacturing a filled packette having a closure where a film is advanced from a feed roller to a punch that produces a series of holes in the film. Individual closures are then positioned into each punched hole and ultrasonically welded into place. The film is folded and oriented vertically so that heat sealing may be used to form the side and bottom edges of individual pockets. The film is then clipped to form individual pockets and filed with the appropriate amount of desired material from a bulk feeder. The filled pockets may be sealed along the top edge to form a closed packette and die cut to form the final packette shape.
1 . An apparatus for forming a packette, comprising:
a feed roll for supplying a substrate in a horizontal orientation;
means for positioning a closure on said substrate;
a guide for reorienting said substrate and said closure from the horizontal orientation to a vertical orientation;
means for forming a packette from said substrate and said closure while said substrate is in the vertical orientation.
2 . The apparatus of claim 1 , wherein said guide comprises a continuous sheet that transitions said substrate from a horizontal orientation proximate to said means for positioning a closure to a vertical orientation proximate to said means for forming a packette.
3 . The apparatus of claim 2 , wherein said continuous sheet descends vertically from said means for positioning a closure to said means for forming a packette.
4 . The apparatus of claim 3 , wherein said continuous sheet includes a compound curve.
5 . The apparatus of claim 4 , wherein said continuous sheet gradually folds into two opposing sides so that said substrate is folded in half when transitioned from the horizontal orientation to the vertical orientation.
6 . The apparatus of claim 5 , wherein said means for forming a packette from said substrate and said closure comprises a vertical form fill and seal machine.
7 . A method of forming a packette, comprising the steps of:
horizontally advancing a film of substrate;
attaching a closure to said substrate;
reorienting said substrate vertically using a guide;
vertically advancing said substrate while forming and filling packettes in said substrate.
8 . The method of claim 7 , wherein said guide comprises a continuous sheet that transitions said substrate from a horizontal orientation proximate to said means for positioning a closure to a vertical orientation proximate to said means for forming a packette.
9 . The apparatus of claim 8 , wherein said continuous sheet descends from said means for positioning a closure to said means for forming a packette.
10 . The apparatus of claim 9 , wherein said continuous sheet includes a compound curve.
11 . The apparatus of claim 10 , wherein said continuous sheet gradually folds into two opposing sides so that said substrate is folded in half as it transitions from the horizontal orientation to the vertical orientation.
