Abstract

A material handling vehicle may include a clamp assembly, the clamp assembly including a housing, a grip assembly, and a power source. The grip assembly may be pivotally engaged with the housing. The power source may be in electrical communication with the grip assembly. The grip assembly includes a lobe pivotally engaged with the housing and a contact supported by the lobe, the contact being electrically conductive.

First claim

What is claimed is:

1. A material sorting system adapted to engage a material handling vehicle, the material sorting system comprising:
a clamp assembly configured to transfer power or a communication signal, the clamp assembly comprising:
a first grip arm; and
a second grip arm, the second grip arm laterally opposing the first grip arm; and

a base, the base including fork pockets adapted to receive a pair of forks from the material handling vehicle, the base comprising:
at least one electrical contact within the base, the at least one electrical contact being adapted to engage with a corresponding electrical contact on the clamp assembly.

2. The material sorting system of claim 1 , wherein the base further comprises:
a top wall;
a bottom wall spaced apart from the top wall; and
a center wall arranged between the top wall and the bottom wall.

3. The material sorting system of claim 2 , wherein the at least one electrical contact within the base is adjacent to the center wall.

4. The material sorting system of claim 1 , further comprising:
a carousel assembly coupled to the base, the carousel assembly including:
a plurality of storage units; and
an actuation mechanism configured to move the plurality of storage units relative to the base.

5. The material sorting system of claim 4 , wherein the at least one electrical contact is adapted to engage with the corresponding electrical contact on the clamp assembly to transfer power or the communication signal between the material handling vehicle and the carousel assembly.

6. The material sorting system of claim 1 , wherein the at least one electrical contact is a first power contact on a top side to the first grip arm, and wherein the first grip arm further includes a second power contact on a bottom side, opposite the top side.

7. The material sorting system of claim 1 , wherein the second grip arm includes:
a first signal contact on a top side of the second grip arm; and
a second signal contact on a bottom side of the second grip arm opposite the top side.

8. A material sorting system adapted to engage a material handling vehicle, the material sorting system comprising:
a base including fork pockets adapted to receive a pair of forks from the material handling vehicle;
at least one electrical contact within the base; and
a carousel assembly coupled to the base, the carousel assembly including:
a plurality of storage units; and
an actuation mechanism configured to move the plurality of storage units relative to the base.

9. The material sorting system of claim 8 , further comprising a clamp assembly arranged between the pair of forks, the clamp assembly including:
a housing;
a first grip arm protruding from the housing and moveably received by the housing; and
a second grip arm protruding from the housing and moveably received by the housing, the second grip arm laterally opposing the first grip arm.

10. The material sorting system of claim 8 , wherein the base further comprises:
a top wall;
a bottom wall spaced apart from the top wall; and
a center wall arranged between the top wall and the bottom wall and dividing the pair of fork pockets.

11. The material sorting system of claim 10 , wherein at least one electrical contact within the base is adjacent to the center wall.

12. The material sorting system of claim 9 , wherein the at least one electrical contact is adapted to engage with the corresponding electrical contact on the clamp assembly to transfer power or a communication signal between the material handling vehicle and the carousel assembly.

13. The material sorting system of claim 8 , wherein the carousel assembly further comprises:
a set of stalks extending from the base; and
a moveable track on each stalk along which the plurality of storage units is coupled.

14. The material sorting system of claim 13 , wherein the set of stalks include indicator lights adjacent to a plurality of stop locations for the plurality of storage units and configured to indicate a placement position for picked goods.

15. A method for engaging a material sorting system, the method comprising:
receiving a pair of forks from a material handling vehicle into fork pockets of a base of a carousel assembly;
engaging the fork pockets using a clamp assembly on the material handling vehicle;
transferring power and information between the material handling vehicle and the carousel assembly; and
moving a plurality of storage units on the carousel assembly using an actuation mechanism.

16. The method of claim 15 , further comprising pivoting a first grip arm to electrically contact an electrical contact with a clamp assembly.

17. The method of claim 16 , further comprising transferring power or a communication signal between the material handling vehicle and the carousel assembly via the electrical contact.

18. The method of claim 15 , further comprising moving, using the actuation mechanism, the plurality of storage units between stop locations along a moving track.

19. The method of claim 15 , wherein the material sorting system comprises:
a top wall;
a bottom wall spaced apart from the top wall; and
a center wall arranged between the top wall and the bottom wall and dividing the pair of fork pockets.

20. The method of claim 15 , further comprising indicating a placement position of picked goods using a plurality of indicator lights.
