Abstract

An accumulation table is disclosed. The accumulation table includes a frame, a first conveyor, a second conveyor, and an adjustable discharge chute. Each conveyor has a U-shaped product carrying section on the top of the frame and an arcuate return section located on the bottom of the frame. Some embodiments further include non-linear tracks located between two conveyor chains to direct one of the conveyor chains towards the adjustable discharge chute.

3. The accumulation table according to claim 1, further comprising a guide rail mounted to said frame.

4. The accumulation table according to claim 1, further comprising a return shoe operatively connected to said bottom of said frame and in sliding engagement with said C-shaped return section of said first conveyor or said second conveyor.

5. The accumulation table according to claim 1, further comprising at least one sprocket adapted to drive said first conveyor or said second conveyor, said at least one sprocket located where said product carrying section meets said return section.

6. The accumulation table according to claim 1, an upstream conveyor adjacent one of said first conveyor or said second conveyor.

7. The accumulation table according to claim 1, a downstream conveyor adjacent one of said first conveyor or said second conveyor.

8. The accumulation table according to claim 1, an upstream conveyor in-line with one of said straight sections.

9. The accumulation table according to claim 1, a downstream conveyor in-line with one of said straight sections.

10. The accumulation table according to claim 1, further comprising a clamp for securing said adjustment member.

11. The accumulation table according to claim 10, wherein said clamp is comprised of a hand knob and threaded rod.

12. The accumulation table according to claim 1, wherein said at least two parallel non-linear track sections creates a gap between two of said conveyor chains.

13. The accumulation table according to claim 12, further comprising a component mounted to said frame at said gap.

14. The accumulation table according to claim 13, wherein said component is selected from the group consisting of a guide rail, a gate, and said adjustable discharge chute.

15. The accumulation table according to claim 12, further comprising a plug for insertion into said gap.

16. The accumulation table according to claim 15, further comprising a component operatively connected to said plug.

17. The accumulation table according to claim 16, wherein said component is selected from the group consisting of a guide rail, a gate, and said adjustable discharge chute.

18. The accumulation table according to claim 1, further comprising a gate mounted to said frame and adapted to block said adjustable discharge chute.

19. The accumulation table according to claim 18, wherein said gate has a first sliding member and a second sliding member.

20. The accumulation table according to claim 19, further comprising a first actuator connected to said first sliding member and a second actuator connected to said second sliding member.

21. The accumulation table according to claim 20, wherein said first actuator and said second actuator are pneumatic.
