Baling system buckles for securing a bale
A buckle for use in securing a band around a bale of material includes a socket member having an aperture formed therein and a wedge member having a portion shaped to maximize friction with a band and a rounded portion opposite the portion shaped to maximize friction with a band. The wedge member is initially connected to the socket member by at least one frangible link in an initial orientation having the rounded portion oriented toward the aperture in the socket member and the portion shaped to maximize friction with a band oriented away from the aperture. The buckle is used in a automated method wherein both ends of a band extending around a bale are clamped to the wedge member, the wedge member is rotated to a final position wherein the portion shaped to maximize friction with a band of the—wedge member is oriented toward the aperture and urged into the aperture, thereby capturing, both ends of the band between the portion shaped to maximize friction with a band of the wedge member and the socket member.
1. A buckle for use in securing a band around a bale of material, the buckle comprising:
a socket member having an aperture formed therein; and
a wedge member having a portion shaped to maximize friction with the band and a rounded portion opposite said portion shaped to maximize friction with the band; wherein said wedge member is initially connected to said socket member by at least one frangible link in an initial orientation having said rounded portion oriented toward said aperture in said socket member and said portion shaped to maximize friction with the band oriented away from said aperture, and wherein rotation of said wedge member out of the initial orientation relative to said socket member causes said frangible links to fracture.
2. The buckle as in claim 1 wherein said portion shaped to maximize friction with the band of said wedge member is insertable into said aperture in said socket member.
3. The buckle as in claim 2 wherein said wedge member includes
first and second end walls,
said aperture includes respective first and second internal end walls, and
said end walls of said wedge member each include serrations interlockable with matching serrations on said internal end walls of said aperture, said serrations inhibiting removal of said portion shaped to maximize friction with the band of said wedge member from said aperture once inserted therein.
4. A single piece buckle for use in securing a band around a bale of material, the single piece buckle comprising:
a socket member having an aperture formed therein; and
a wedge member having a portion shaped to maximize friction with the band and a rounded portion opposite said portion shaped to maximize friction with the band; wherein said wedge member is initially connected to said socket member by at least one frangible link in an initial orientation having said rounded portion oriented toward said aperture in said socket member and said portion shaped to maximize friction with the band oriented away from said aperture, wherein rotation of said wedge member out of the initial orientation relative to said socket member causes said frangible links to fracture.
5. The single piece buckle as in claim 4 wherein said portion shaped to maximize friction with the band of said wedge member is insertable into said aperture in said socket member.
6. The single piece buckle as in claim 5 wherein said wedge member includes
first and second end walls,
said aperture includes respective first and second internal end walls, and
said end walls of said wedge member each include serrations interlockable with matching serrations on said internal end walls of said aperture, said serrations inhibiting removal of said portion shaped to maximize friction with the band of said wedge member from said aperture once inserted therein.
7. A method for clamping a band around a bale of material, the method comprising the steps of:
providing a buckle having:
a socket member having an aperture formed therein; and
a wedge member having a portion shaped to maximize friction with the band and a rounded portion opposite the portion shaped to maximize friction with the band; wherein
said wedge member is initially connected to the socket member by at least one frangible link in an initial orientation having the rounded portion oriented toward the aperture in the socket member and the portion shaped to maximize friction with the band oriented away from the aperture;
clamping both ends of the band extending around a bale to the wedge member; rotating the wedge member out of the initial position toward a final position wherein the portion shaped to maximize friction with the band of the wedge member is oriented toward the aperture in the socket member;
urging the portion shaped to maximize friction with the band of the wedge member into the aperture in the socket member and capturing both ends of the band between the portion shaped to maximize friction with the band of the wedge member and the socket member; and
rotating said wedge member out of the initial orientation relative to said socket member causing said frangible links to fracture.
8. The method as in claim 7 wherein, during said rotating step, both ends of the band are wrapped around the rounded portion of the wedge member.
9. The method as in claim 8 wherein the wedge member includes
first and second sidewalls,
the aperture includes respective first and second internal sidewalls, and wherein,
during the band insertion step, both ends of the band are captured between both sidewalls of the wedge and the respective internal sidewalls of the aperture.
