Split roller and modular conveying assemblies formed therefrom
View Patent ↗A split roller including at least two parts joined together forms the roller having a length defined between roller ends. At least two of the at least two parts are joined along a joint extending between the roller ends. A roller cradle assembly and a modular conveying assembly can be assembled including the roller.
1. A roller cradle assembly for use in a modular conveying assembly, said assembly comprising:
a first hinge member having a hinge opening;
a second hinge member having a hinge opening;
a supporting shaft extending between said first hinge member and said second hinge member wherein said supporting shaft runs longitudinally perpendicular to said hinge openings, said first hinge member, second hinge member, and supporting shaft being formed as a single piece; and
a roller wrapped around said supporting shaft and extending axially between opposing roller ends, said roller being formed from at least two parts joined along a joint extending between said two ends.
2. The roller cradle assembly as in claim 1 , in which adjacent longitudinal edges of said at least two of said at least two parts are joined by a hinge.
3. The roller cradle assembly as in claim 2 , in which said hinge is a living hinge.
4. The roller cradle assembly as in claim 1 , in which said at least two parts are joined by a method selected from a group consisting of mechanical fasteners, thermal bonding, and chemical bonding.
5. The roller cradle assembly as in claim 1 , in which said roller is formed from two parts, each of said parts forming a half of said roller.
6. The roller cradle assembly as in claim 1 , in which at least one of said at least two parts is formed as a single piece extending the entire length of said roller.
7. A modular conveying assembly for conveying an object, said assembly comprising:
a plurality of chain modules assembled in an edge to edge relation to form a continuous belt, at least one of said modules having side edges joined by leading and trailing edges;
at least one hinge pin joining said at least one of said modules and said adjacent chain module;
at least one cradle interposed between said at least one of said modules and said adjacent chain module, said cradle including a supporting shaft extending between first and second hinge members and formed as a single piece with said first and second hinge members; and
a roller wrapped around said supporting shaft and extending axially between opposing roller ends, said roller being formed from at least two parts joined along a joint extending between said roller ends to form said roller.
8. The modular conveying assembly as in claim 7 , in which adjacent longitudinal edges of at least two of said at least two parts are joined by a hinge.
9. The modular conveying assembly as in claim 8 , in which said hinge is a living hinge.
10. The modular conveying assembly as in claim 7 , in which said at least two parts are joined by a method selected from a group consisting of mechanical fasteners, thermal bonding, and chemical bonding.
11. The modular conveying assembly as in claim 7 , in which said roller is formed from two parts, each of said parts forming a half of said roller.
12. The modular conveying assembly as in claim 7 , in which at least one of said at least two parts is formed as a single piece extending the entire length of said roller.
