Abstract

A cartridge assembly for use in a load zone support includes a shaft that is able to be connected to an idler frame of a belt conveyor system. The cartridge assembly further includes a support plate coupled to the shaft and a wear pad coupled to the support plate.

First claim

What is claimed is:

1. A cartridge assembly for removable installation on an idler frame disposed in a load zone of a belt conveyor system supporting a conveyor belt, the idler frame including an inner perch support having a first slot for supporting an idler roller shaft, the idler frame including an outer perch support having a second slot for supporting the idler roller shaft, the cartridge assembly comprising:
an elongated support member having a first end and a second end, said first end of said elongated support member being configured to be removably received in the first slot of the inner perch support, said second end of said elongated support member being configured to be removably received in the second slot of the outer perch support, wherein a support member length extending between said first end and said second end of said elongated support member corresponds to a distance between the first slot of the inner perch support and the second slot of the outer perch support;
a first removable retaining device selectively retaining at least one of said first end and said second end of said elongated support member in position relative to at least one of said inner and outer perch supports; and
a wear pad disposed above said elongated support member, said wear pad having a planar upper surface, said wear pad having a wear pad length generally aligned with said support member, said wear pad having a wear pad width less than said wear pad length, said wear pad being supported by said elongated support member, said wear pad being releasably secured in position by at least one removable fastener in contact with said wear pad.

2. The cartridge assembly of claim 1 , wherein said elongated support member comprises a shaft.

3. The cartridge assembly of claim 1 , wherein said first end of said elongated support member is configured to slidingly engage the first slot of the inner perch support, and wherein said second end of said elongated support member is configured to slidingly engage the second slot of the outer perch support.

4. The cartridge assembly of claim 1 , wherein said first end of said elongated support member comprises a first groove configured to slidingly engage the first slot of the inner perch support, and wherein said second end of said elongated support member comprises a second groove configured to slidingly engage the second slot of the outer perch support.

5. The cartridge assembly of claim 1 , wherein said support member length is approximately equal to a length of the idler roller shaft.

6. The cartridge assembly of claim 1 , wherein said wear pad width is dimensioned to extend to but not contact an adjacent idler frame in the load zone.

7. The cartridge assembly of claim 6 , wherein an overall width of said cartridge assembly is approximately 10 inches.

8. The cartridge assembly of claim 1 , wherein an overall width of said cartridge assembly is slightly greater than a support base width of a support base of the idler frame.

9. The cartridge assembly of claim 1 , wherein said support member is configured to be solely supported by said the inner and outer perch supports.

10. The cartridge assembly of claim 1 , further comprising:
a support plate coupled to said elongated support member, said support plate having a support plate width greater than a support member width of said elongated support member, wherein said wear pad is removably mounted to said support plate.

11. The cartridge assembly of claim 10 , wherein said removable fastener is removably mounted to said support plate.

12. The cartridge assembly of claim 10 , further comprising:
a second wear pad removably mounted to said support plate.

13. The cartridge assembly of claim 10 , wherein said removable fastener includes a nut, wherein said nut is disposed on an opposite side of said support plate relative to said wear pad.

14. The cartridge assembly of claim 1 , wherein said wear pad comprises first, second and third sidewalls, each said first sidewall being shorter than each of said second and third sidewall, wherein said first end of said support member is disposed outward of said first sidewall.

15. The cartridge assembly of claim 14 , wherein said wear pad is generally rectangular.

16. The cartridge assembly of claim 1 , wherein said removable retaining device comprises a clip.

17. An idler frame for use in a load zone of a belt conveyor system supporting a conveyor belt, comprising:
an inner perch support having a first slot;
an outer perch support having a second slot; and
a cartridge assembly removably installable on said inner and outer perch support, said cartridge assembly comprising:
an elongated support member having a first end and a second end, said first end of said elongated support member being removably received in said first slot of said inner perch support, said second end of said elongated support member being removably received in said second slot of said outer perch support, wherein a support member length extending between said first end and said second end of said elongated support member corresponds to a distance between said first slot of said inner perch support and said second slot of said outer perch support;
a first removable retaining device selectively retaining at least one of said first end and said second end of said elongated support member in position relative to at least one of said inner and outer perch supports; and
a wear pad disposed above said elongated support member, said wear pad having a planar upper surface, said wear pad having a wear pad length generally aligned with said support member, said wear pad having a wear pad width less than said wear pad length, said wear pad being supported by said support member, said wear pad being releasably secured in position by at least one removable fastener in contact with said wear pad.

18. The idler frame of claim 17 , wherein said first end of said elongated support member slidingly engages said first slot of said inner perch support, and wherein said second end of said elongated support member slidingly engages said second slot of said outer perch support.

19. The idler frame of claim 17 , wherein said first end of said elongated support member comprises a first groove slidingly engaging said first slot of said inner perch support, and wherein said second end of said elongated support member comprises a second groove slidingly engaging said second slot of said outer perch support.

20. The idler frame of claim 17 , wherein an overall width of said cartridge assembly is slightly greater than a support base width of a support base of said idler frame.

21. The idler frame of claim 17 , wherein said support member is solely supported by said inner and outer perch supports.

22. The idler frame of claim 17 , further comprising:
a support plate coupled to said elongated support member, said support plate having a support plate width greater than a support member width of said elongated support member, wherein said wear pad is removably mounted to said support plate.

23. A method for removably installing a cartridge assembly on an idler frame disposed in a load zone of a belt conveyor system supporting a conveyor belt, the idler frame including an inner perch support having a first slot for supporting an idler roller shaft, the idler frame including an outer perch support having a second slot for supporting the idler roller shaft, the method comprising:
aligning an elongated support member
