Drive system and method for forming a transportable container for bulk goods

摘要

A packaging system (20) for forming and filling a transportable container (22) of plurality of bulk goods includes a frame (26) having a bottom support (48) and an upper support (32). An upper turntable (34) is rotatably supported within the upper support (32) and a lower turntable (50) is rotatably supported on the bottom support (48). A drive system (58) includes at least one pulley system (62, 64, 66) interconnected to the upper and lower turntables (34, 50) for simultaneously driving and synchronizing rotation of the upper and lower turntables (34, 50) with the at least one pulley system (62, 64, 66). A slip frame former (42) extends downwardly from the upper turntable (34) and a roll of stretch wrap (92) is disposed in overlapping relationship with the slip frame former (42) and the bottom support (48) during simultaneous and synchronized rotation of the turntables (34, 50) with the at least one pulley system (62, 64, 66).

主权项

1. A method of forming and filling a transportable container comprising:
simultaneously rotating an upper turntable including a slip frame former and a lower turntable disposed on a bottom support with a drive to synchronize a rotational speed of said upper and lower turntables; applying stretch wrap to at least a portion of the slip frame former and a transportable base disposed on the lower turntable during the simultaneous rotation of the upper and lower turntables to form a transportable container extending therebetween; moving at least one of the upper turntable and the bottom support relative to one another to disengage previously disposed portions of stretch wrap from the slip frame former and overlap the previously disposed portions of stretch wrap and the slip frame former with the stretch wrap; and disengaging rotation of the upper turntable with the drive during the relative movement of the upper turntable and the bottom support and continuing to drive rotation of the upper turntable using only the overlapped layers of stretch wrap extending between the transportable base and the slip frame former.
