Abstract

A conveyor system aligner, method of aligning and continuous aligning belt includes providing a belt support assembly having a generally vertical support surface and a channel defined in the support surface. A belt drive propels the aligning belt along the support surface and items, such as cartons, are conveyed past the aligning belt. A continuous aligning belt is provided that has a contact portion and a guide member. The contact portion has a contact surface and a glide surface. The glide surface is configured to travel along the support surface. The guide member is adapted to be captured by the channel and travels in the channel to support the aligning belt.

Claims

1. A conveyor system aligner, comprising:

a belt support assembly having a generally vertical support surface and a channel defined in said support surface;

a belt drive;

a continuous aligning belt that is driven by said belt drive, said aligning belt having a contact portion and a guide member, said contact portion having a contact surface and a glide surface, said glide surface is configured to travel along said support surface, said guide member adapted to be captured by said channel and travel in said channel to support said belt;

wherein at least a portion of said guide member has a cross section that increases in width away from said contact portion and wherein said channel has an interior surface configuration that engages said portion of said guide member; and

a horizontal conveyor, said horizontal conveyor adapted to convey articles past said aligning belt.

2. The aligner as claimed in claim 1 wherein said generally vertical support surface and said glide surface are generally planar.

3. The aligner as claimed in claim 1 wherein said portion of said guide member has opposite surfaces that diverge away from said glide surface.

4. The aligner as claimed in claim 3 wherein said opposite surfaces are generally planar.

5. The aligner as claimed in claim 3 wherein said opposite surfaces are non-planar.

6. The aligner as claimed claim 3 including spaced apart notches defined in said guide member.

7. The aligner as claimed in claim 1 wherein said contact portion and said guide member are separate members that are fused together.

8. The aligner as claimed in claim 1 wherein at least one of said contact portion and said guide member are made from urethane.

9. The aligner as claimed in claim 1 including a plurality of rotating pulleys supporting said belt.

10. The aligner as claimed in claim 9 wherein at least one of said pulleys has a first belt-engaging surface that is configured to interface with said contact surface and wherein at least one other of said pulleys has a second belt-engaging surface that is configured to interface with said glide surface and said guide member.

11. The aligner as claimed in claim 9 wherein said belt drive includes one of said pulleys and a motor that rotates said one of said pulleys.

12. The alignek as claimed in claim 9 including a take-up assembly, said take-up assembly including one of said pulleys.

13. The aligner as claimed in claim 1 wherein said aligning belt has a portion that is adapted to be separated to facilitate mounting of said aligning belt to said belt support assembly.

14. The aligner as claimed in claim 3 wherein said glide surface slides along said support surface and said guide member slides in said channel.

15. The aligner as claimed in claim 3 wherein said channel captures said portion of said guide member with engaging surface portions that are configured to be engaged by said opposite surfaces of said guide member.

16. The aligner as claimed in claim 1 wherein said horizontal conveyor comprises a conveying belt.

17. The aligner as claimed in claim 1 including at least one synchronizing mark on said aligning belt that is adapted to synchronize speed between said horizontal conveyor and said aligning belt.

18. The aligner as claimed in claim 1 wherein said at least a portion of said guide member has a V-shaped cross section defining outer surface portions that diverge away from said contact portion and wherein at least a portion of said channel has V-shaped surface portions that engage said outer surface portions of said guide member.
