Abstract

A strapping system for an agricultural implement includes a strap feeding assembly positioned on a first side of a baling chamber and a rotating gripper assembly positioned on a second side of the baling chamber, opposite the first side. The strapping system also includes a track assembly configured to direct a strap from the strap feeding assembly to the rotating gripper assembly. The rotating gripper assembly is configured to grip the strap while the rotating gripper assembly is in a first orientation, and while the rotating gripper assembly is in a second orientation that enables crop flow in a rearward direction to draw the strap through the strap feeding assembly.

First claim

The invention claimed is:

1. A strapping system for an agricultural implement comprising:
a needle comprising a gripping assembly;
a forward plunger having a material-facing surface having a slot formed thereon, the slot being configured to direct a strap from a first side of a baling chamber to a second side of the baling chamber, the slot comprising a track assembly having a gated channel; and
a rotating gripper assembly positioned on the second side of the baling chamber and configured to rotate from a first orientation for receiving the strap from the slot to a second orientation that enables transfer of the strap to the gripping assembly of the needle,
wherein the gripping assembly of the needle is positioned on the second side of the baling chamber for transferring an end of the strap from the second side toward the first side of the chamber.

2. The strapping system of claim 1 , further comprising a strap feeding assembly positioned on the first side of the baling chamber and configured to propel the strap through the slot.

3. The strapping system of claim 1 , further comprising an orientating gripper positioned on the first side of the baling chamber and configured to grip the strap and to rotate to facilitate alignment of a free end of the strap with the slot.

4. The strapping system of claim 3 , wherein the gripping assembly is configured to receive and to capture the strap from the rotating gripper assembly.

5. The strapping system of claim 4 , wherein the rotating gripper assembly comprises a semi-circular gripper configured to capture the strap, and the gripping assembly of the needle comprises a duck-bill gripper configured to capture the strap.

6. A strapping system for an agricultural implement comprising:
a strap feeding assembly configured to propel a strap from a first side of a baling chamber to a second side of the baling chamber,
a rotating gripper assembly disposed on the second side of the baling chamber and configured to receive a portion of the strap and to rotate the strap toward a rear end of the baling chamber as a compressible material collects in the baling chamber; and
a needle disposed on the second side of the baling chamber and having a gripping assembly configured to capture the strap from the rotating gripper assembly while the strap is rotated toward the rear end of the baling chamber, and to transfer an end of the strap across the baling chamber toward the first side of the chamber.

7. The strapping system of claim 6 , wherein the rotating gripper assembly is configured to be coupled to a frame of the agricultural implement.

8. The strapping system of claim 6 , wherein the needle is configured to move through the baling chamber around the compressible material in the baling chamber to transfer the strap to a sealing assembly.

9. The strapping system of claim 8 , wherein the sealing assembly seals a first portion of the strap to a second portion of the strap to form the strap into a loop surrounding the compressible material in the baling chamber.

10. The strapping system of claim 6 , wherein the needle comprises a hollow portion, and a cable is disposed within the hollow portion, the cable being configured to operate the gripping assembly of the needle.

11. The strapping system of claim 6 , further comprising a track assembly disposed in a material-facing surface of a forward plunger, wherein the track assembly is configured to guide the strap from the first side to the second side of the baling chamber.
