Abstract

A conveyor system includes a conveying surface for conveying articles as defined by a plurality of rollers and a frame. Each of the rollers has an axle. The frame is made up of at least two frame members that are spaced apart a distance that corresponds with a length of at least one of the plurality of rollers. A plurality of axle retainers is connected with at least one of the frame members. Each of the axle retainers has a base and a plurality of axle retaining openings that are each adapted to receiving an axle at an end of one of the rollers. At least two of the openings are fixedly at different angles to the base. In this manner, the axle retainers are capable of mounting the rollers at more than one angle with respect to the at least one of the frame members as determined by which of the axle-retaining openings receives the axle. Each roller-mounting angle corresponds to a different orientation of the base with respect to the at least one of the frame members.

Claims

1. A conveyor system, comprising:

a conveying surface for conveying articles, said conveying surface defined by a plurality of rollers, each of said rollers comprising an axle;

a frame made up of at least two frame members that are spaced apart a distance that corresponds with a length of at least one of said plurality of rollers; and

a plurality of axle retainers connected with at least one of said frame members, each of said axle retainers having a base and a plurality of axle retaining openings that are each adapted to receiving said axle at an end of one of said rollers, at least two of said openings being fixedly at different angles to said base, wherein said axle retainers are capable of mounting said rollers at more than one angle with respect to said at least one of said frame members as determined by which of said axle retaining openings receives said axle, each of said more than one mounting angle of said rollers corresponding to a different orientation of said base with respect to said at least one of said frame members.

2. The conveyor system as claimed in claim 1 wherein said axle retainers and said at least one of said frame members have complimentary configurations that allow said axle retainers to be mounted at different orientations to said at least one of said frame members to change which of said retaining openings is used to retain one of said axles.

3. The conveyor system as claimed in claim 2 wherein said complementary configurations comprise T-shaped extensions of said axle retainers and vertical slots in said at least one of said frame members to receive said extensions.

4. The conveyor system as claimed in claim 3 wherein said T-shaped extensions are press-fit into said slots in order to maintain said axle retainers connected to said at least one of said frame members.

5. The conveyor system as claimed in claim 1 including a vertically reciprocating diverter that reciprocates between a non-diverting position below said conveying surface and a diverting position at least partially above said conveying surface, wherein said at least one of said frame members extends along at least one side of said diverter wherein said diverter can be mounted at different angles with respect to said conveying rollers.

6. The conveyor system as claimed in claim 1 wherein said rollers are skewed with respect to both of said frame members.

7. The conveyor system as claimed in claim 6 that comprises at least one chosen from an unscrambling conveyor and an aligning conveyor.

8. The axle retainer as claimed in claim 1 wherein each of said openings comprises a hexagonally shaped opening.

9. The conveyor system as claimed in claim 1 wherein said axle retainers are made from a polymeric material.

10. An axle retainer, comprising:

a base; and

a plurality of axle-retaining openings that are each adapted to receiving an end of a roller axle, at least two of said openings being fixedly at different angles to said base, whereby said axle retainers are capable of mounting rollers at more than one angle to said base as determined by which of said at least two openings is receiving the axle, which of said at least two openings is receiving the axle is determined by an orientation of said base.

11. The axle retainer as claimed in claim 10 wherein each of said openings comprises a hexagonally shaped opening.

12. The axle retainer as claimed in claim 10 that is made from a polymeric material.

13. The axle retainer as claimed in claim 10 including a mounting surface of said base opposition from said openings.

14. The axle retainer as claimed in claim 13 wherein said mounting surface is defined by extensions of said base.

15. The axle retainer as claimed in claim 14 wherein said extensions comprise T-shaped extensions.
