Abstract

A conveyor assembly comprising a main conveyor having a first side frame and a second side frame, with the first and/or second side frames including a side portion and a support surface. One or more input conveyors having a discharge end are joined to the main conveyor with a bottom portion of the discharge end being positioned on the support surface whereby the input conveyors are accurately mounted in close proximity to the main conveyor to promote the conveyance of items from the input conveyors onto the main conveyor.

First claim

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. A conveyor assembly, said conveyor assembly comprising:
a main conveyor comprising a belt conveyor having a top surface and a belt with said belt having a first edge and a second edge defining a width of said belt and being moveable over said top surface, said main conveyor further comprising a first side frame and a second side frame, said first side frame including a side portion and a support surface, said support surface extending laterally outward beyond an edge of said top surface with said side portion extending upwardly relative to said support surface, wherein said first side frame further includes a generally horizontally oriented flange located above said side portion, and wherein said top surface extends over said flange; and
an input conveyor defining a conveying surface and having a discharge end;
said input conveyor being mounted to said first side frame of said main conveyor with said discharge end positioned on said support surface.

2. The conveyor assembly of claim 1 , wherein said discharge end of said input conveyor includes a bottom portion, and wherein said bottom portion is positioned on said support surface.

3. The conveyor assembly of claim 2 , wherein said input conveyor includes a pair of side rails and said side rails include said bottom portion.

4. The conveyor assembly of claim 1 , wherein said support surface comprises a support wall defining a ledge.

5. The conveyor assembly of claim 4 , wherein said ledge comprises an elongate ledge and said support surface is generally horizontally oriented.

6. The conveyor assembly of claim 4 , wherein said side portion comprises a side wall with said side wall being oriented generally orthogonally relative to said support wall.

7. The conveyor assembly of claim 1 , wherein said flange extends outwardly relative to said side portion and said top surface extends outwardly beyond a plane defined by said side portion of said first side frame.

8. The conveyor assembly of claim 7 , wherein said first edge of said belt extends outwardly beyond a plane defined by said side portion of said first side frame.

9. The conveyor assembly of claim 1 , wherein said first side frame comprises a plurality of elongate side channels.

10. The conveyor assembly of claim 1 , wherein said input conveyor comprises a roller conveyor oriented at a non-perpendicular angle relative to said main conveyor with said discharge end including a first side rail and a second side rail with a plurality of rollers with progressively shorter axial lengths extending between said first side rail and said second side rail.

11. The conveyor assembly of claim 1 , further including a guard assembly mounted at and extending with said first side frame, said guard assembly including an opening at said discharge end of said input conveyor, with said guard assembly including a guard member located inwardly above said top surface of said main conveyor and inwardly above said first edge of said belt.

12. The conveyor assembly of claim 11 , wherein said guard assembly further includes a guide member against which said first edge of said belt can contact.

13. The conveyor assembly of claim 1 , wherein said second side frame includes a side portion and a support surface, said support surface of said second side frame extending laterally outward beyond an opposite edge of said top surface with said side portion of said second side frame extending upwardly relative to said support surface of said second side frame, and wherein said support surface of said second side frame is configured to have a discharge end of another input conveyor positioned thereon.

14. The conveyor assembly of claim 1 , wherein said belt has a first portion joined together with a second portion, with said first portion and said second portion comprising a conveying surface configured to support items for conveyance on said main conveyor, and wherein said first portion provides greater frictional surface resistance than said second portion.

15. The conveyor assembly of claim 14 , wherein said belt further includes a third portion joined together with said first portion, and wherein said first portion provides greater frictional surface resistance than said third portion and wherein said first portion is located between said third and second portions.

16. The conveyor assembly of claim 14 , wherein said belt comprises a multi-layer belt having a top layer and a second layer beneath said top layer with said top layer comprising said first portion and said second portion.

17. The conveyor assembly of claim 1 , wherein said main conveyor includes an input end and a discharge end, and wherein at least one of said input end and said discharge end include an end pulley assembly around which said belt travels to enable said belt to travel in a direction opposite that from which it enters said end pulley assembly, and wherein said end pulley assembly comprises a top roller and a bottom roller having parallel axes of rotation with the axis of rotation of said top roller being positioned vertically higher than the axis of rotation of said bottom roller.

18. The conveyor assembly of claim 1 , wherein said top surface defines a slider bed comprising one or more panel members.

19. A conveyor assembly, said conveyor assembly comprising:
a main conveyor comprising a belt conveyor having a top surface and a moveable belt with said belt having a first edge and a second edge defining a width of said belt and being moveable over said top surface, said main conveyor further comprising a first side frame and a second side frame, said first side frame including a side portion and a support surface, said support surface comprising a wall defining a ledge extending laterally outward beyond an edge of said top surface with said side portion extending upwardly relative to said support surface, wherein said first side frame further includes a generally horizontally oriented flange located above said side portion, and wherein said top surface extends over said flange; and
an input conveyor defining a conveying surface and having a discharge end with said discharge end including a bottom portion;
said input conveyor being mounted to said first side frame of said main conveyor with said bottom portion of said discharge end positioned on said ledge of said support surface.

20. The conveyor assembly of claim 19 , wherein said support wall comprises an elongate ledge and is generally horizontally oriented, and said side portion comprises a side wall with said side wall being oriented generally orthogonally relative to said support wall.

21. The conveyor assembly of claim 20 , wherein said input conveyor includes a pair of side rails and said side rails include said bottom portion.

22. The conveyor assembly of claim 19 , wherein said second side frame includes a side portion and a support surface, said support surface of said second side frame comprising a wall defining a ledge extending laterally outward beyond an opposite edge of said top surface with said side portion of said second side frame extending upwardly relative to said support surface of said second side frame, and wherein said ledge of said second side frame is configured to have a discharge end of another input conveyor positioned thereon.

23. A conveyor assembly, said conveyor assembly comprising:
a main conveyor having a first side frame an
