Abstract
Bale strap assemblies for strapping a pressed bale are discussed herein. The bale strap assemblies may include a strap positioning assembly having a plurality of strap assemblies and a return chute assembly having a plurality of return chutes for returning straps to the strap assemblies for strapping the pressed bale. The strap position assembly and return chute assembly incorporate cylinders to move between different positions during a strapping cycle. Exemplary embodiments include provisions for accommodating a press turntable of a down packer and registration means for providing a greater number of straps to strap a bale than a corresponding number of strap assemblies.
Claims24
A method for strapping compressible materials comprising:
- compressing a plurality of compressible materials against a plate, said plate defining a plane;
- exposing the compressed materials for strapping;
- rotating at least three strap assemblies mounted on a frame from a position below the plane defined by the plate while the compressible materials are still undergoing a pressed cycle, said frame comprising a shock absorber;
- providing a plurality of straps around the compressed materials to strap the compressed materials;
- lowering the plurality of strap assemblies to the position below the plane defined by the plate;
- and
- wherein the rotating step comprises two actuator cylinders operated serially to move the frame from the position below the plane to an operating position.
A combination strap assembly and baling press comprising:
- a base plate for pressing pressible materials against, said base plate defining a plane,
- a baling chamber defining a cavity for pressing a bale;
- a strap positioning assembly comprising a plurality of strap assemblies, said strap positioning assembly comprising an upper end positioned away from the base plate and a lower end positioned closer to the base plate than the upper end;
- a return chute assembly comprising a plurality of return chutes for redirecting straps supplied by the plurality of strap assemblies;
- a structure comprising a moveable arm for moving the plurality of strap assemblies from a position substantially below the plane defined by the base plate to a position above, at least in part, the plane;
- and
- a shock absorber mounted on the strap positioning assembly between the upper end and the lower end for dampening vibration of the strap positioning assembly, said shock absorber extending further outwardly on the strap positioning assembly towards the baling chamber than any other structure on the strap positioning assembly when in an operating position.
A strap assembly mountable on a baling press having a base plate defining a plane, the strap assembly comprising:
- a strap positioning assembly comprising a frame having a plurality of strap assemblies mounted thereon for providing straps around pressible materials;
- a return chute assembly having a plurality of return chutes for redirecting straps supplied by the plurality of strap assemblies;
- a first pneumatic cylinder and a second pneumatic cylinder, the first and second pneumatic cylinders each comprising a push rod in sliding communication with each other for moving the plurality of strap assemblies a first rotation about a pivot point when the first pneumatic cylinder is actuated and a second rotation about the pivot point when the second pneumatic cylinder is actuated;
- a shock absorber for maintaining a pre-determined gap between the frame and the pressible materials;
- and
- wherein the shock absorber is configured to contact at least one of the baling press and the pressible materials to maintain the pre-determined gap between the frame and the pressible materials.
