Abstract

A roller cradle for use in a modular conveying assembly having a direction of travel in which an object is conveyed includes a first half and a second half. Each of the halves include integral hinge members defining a space therebetween. A roller having an axis of rotation substantially perpendicular to the direction of travel is retained in the space.

Claims

1. A roller cradle for use in a modular conveying assembly having a direction of travel in which an object is conveyed, said cradle comprising:

a first half including a side portion and an integral first hinge member;

a second half formed separately from said first half and including a side portion and a second integral hinge member spaced from said first hinge member and defining a space therebetween; and

a roller retained in said space between said first half and said second half.

2. The roller cradle as in claim 1, in which a shaft extends between said first and second halves through said space, and said shaft retains said roller in said space.

3. The roller cradle as in claim 2, in which said shaft extends through said roller to rotatably mount said roller in said space.

4. The roller cradle as in claim 2, in which each of said first half and second half includes a shaft aperture that receives one end of said shaft.

5. The roller cradle as in claim 2, in which said shaft is formed from two shaft halves, and each shaft half has a semicircular cross section.

6. The roller cradle as in claim 1, including a first cradle side wall having first and second ends, said first end being joined to one of said hinge members, and said second end extending toward the other of said hinge members.

7. The roller cradle as in claim 6, in which said second end interlocks with said other of said hinge members.

8. The roller cradle as in claim 6, including a second cradle side wall having a first end and a second end, said first end of said second cradle side wall being joined to said other of said hinge members, and said second end of said second cradle side wall extending toward said one of said hinge member to frame said space between said hinge members.

9. The roller cradle as in claim 8, in which a shaft extends through said space between said first and second side walls, and said shaft retains said roller in said space.

10. The roller cradle as in claim 1, in which at least one of said hinge members includes more than one meshing eye.

11. The roller cradle as in claim 1, in which at least a portion of said roller extends at least one of above said cradle and below said cradle.

12. The roller cradle as in claim 1, in which said roller has an axis of rotation substantially perpendicular to the direction of travel.

13. A modular conveying assembly for conveying an object in a direction of travel, said assembly comprising:

a plurality of chain modules assembled in an edge to edge relation to form a continuous belt;

at least one hinge pin joining adjacent chain modules, and pivotally connecting the adjacent modules in the direction of belt travel;

at least one roller cradle adjacent at least one of said modules is retained by said at least one pin, said cradle including a first half including a side portion and an integral first hinge member, a second half formed separately from said first half and including a side portion and a second integral hinge member spaced from said first hinge member and defining a space therebetween, and a roller retained in said space between said first half and said second half.

14. The modular conveying assembly as in claim 13, in which said at least one roller cradle includes a shaft extends between said first and second halves through said space, and said shaft retains said roller in said space.

15. The modular conveying assembly as in claim 14, in which said shaft extends through said roller to rotatably mount said roller in said space.

16. The modular conveying assembly as in claim 13, in which said at least one roller cradle includes a first cradle side wall having first and second ends, said first end being joined to one of said hinge members, and said second end extending toward the other of said hinge members.

17. The modular conveying assembly as in claim 13, in which said at least one roller cradle includes at least one of said hinge members having more than one meshing eye.

18. The modular conveying assembly as in claim 13 in which said at least one roller cradle includes at least a portion of said roller extending at least one of above said cradle and below said cradle.

19. The modular conveying assembly as in claim 16, in which said second end interlocks with said other of said hinge members.

20. The modular conveying assembly as in claim 16, in which said at least one roller cradle includes a second cradle side wall having a first end and a second end, said first end of said second cradle side wall being joined to said other of said hinge members, and said second end of said second cradle side wall extending toward said one of said hinge member to frame said space between said hinge members.

21. The modular conveying assembly as in claim 20, in which a shaft extends through said space between said first and second side walls, and said shaft retains said roller in said space.
