The bagger includes a winding spool having tapered ribs and valleys.
Claims20
A device for supplying successive bags from an indefinite length bag assembly to a workstation, the bag assembly having a pair of tape strips and a plurality of bags spaced along the strips, the device comprising;
- a reel assembly for winding tape strips from the lead end of the bag assembly to pull the bag assembly along a path of travel to the workstation and position successive lead bags in the assembly at the workstation, the reel assembly including a first spool for winding a first tape strip in the bag assembly, and a second spool for winding a second tape strip in the bag assembly, each spool including an elongate body, one or more elongate and tapered tape winding surfaces spaced around and extending along the body for winding strip rings at different locations along the length of the body, and one or more strip ring removal recesses, each recess extending along the length of the body from a large diameter body end to a small diameter body end;
- an operative drive having an input member and an output member connecting the input member and each spool;
- a drive motor;
- and
- a drive connection between the drive motor and the input member.
A device for supplying successive bags from an indefinite length bag assembly to a workstation, the bag assembly having a pair of tape strips and a plurality of bags spaced along the strips, the device comprising,
- a reel assembly for winding strips from the lead end of the bag assembly to pull the bag assembly along a path of travel to the workstation and position successive lead bags in the assembly at the workstation, the reel assembly including a pair of winding spools, a motor, an operative drive connecting the motor and the winding spools wherein the motor rotates the spools to wind up one tape strip on each spool;
- each spool including an elongate body, a plurality of elongate ribs spaced around and extending along the body, elongate tape winding surfaces on the ends of the ribs away from the body;
- and a plurality of elongate strip ring removal valleys spaced around and extending along the body between the ribs, the ribs of each spool tapering inwardly from a first large diameter body end to a second small diameter body end;
- and the valleys opening at the small diameter body end to facilitate removal of strip rings wound on the spool;
- wherein rotation of the spools by the motor winds the tapes on the tape winding surfaces at selected locations along the spools to form strip rings.
