Abstract

Systems and methods are disclosed for transition components for gaps in shuttle rails. An example system configured to transport items may include a shuttle configured to support an item, where the shuttle includes a first wheel. The first wheel may have a first side surface, a second side surface, and a middle portion that together form a v-groove. The system may include a first rail configured to engage the first side surface and the second side surface, a second rail configured to engage the first side surface and the second side surface, where the second rail is separated from the first rail, and a first transition block coupled to the first rail. The first transition block may be configured to transfer a load of the shuttle from the first side surface and the second side surface to the middle portion of the wheel.

Claims (48)

1. A system configured to transport items, the system comprising:

a shuttle configured to support an item, the shuttle comprising a first wheel, wherein the first wheel has a first side surface, a second side surface, and a middle portion that together form a v-groove;

a first rail configured to engage the first side surface and the second side surface;

a second rail configured to engage the first side surface and the second side surface, wherein the second rail is separated from the first rail; and

a first transition block coupled to the first rail, the first transition block configured to transfer a load of the shuttle from the first side surface and the second side surface to the middle portion of the wheel, wherein the first transition block comprises:

a first ramp portion having a first incline angle; and

a second ramp portion having a second incline angle that is less than the first incline angle.

2. The system of claim 1 , further comprising:

a second transition block coupled to the second rail, the second transition block configured to transfer the load of the shuttle from the middle portion of the wheel to the first side surface and the second side surface of the wheel.

3. The system of claim 2 , wherein the first transition block is in a first orientation and the second transition block is in a second orientation that is opposite the first orientation.

4. The system of claim 1 , wherein the first ramp portion has a first length, and the second ramp portion has a second length that is greater than the first length.

5. The system of claim 1 , wherein the first ramp portion has a tapered width.

6. The system of claim 1 , wherein the first transition block comprises:

a base; and

an angled blind hole disposed in the base.

7. The system of claim 1 , wherein the first transition block has a length that is equal to or less than a circumference of the first wheel.

8. The system of claim 1 , wherein the first rail does not engage the middle portion of the first wheel, and the second rail does not engage the middle portion of the first wheel.

9. The system of claim 1 , wherein the second rail is configured to move vertically with respect to the first rail.

10. The system of claim 1 , wherein the shuttle further comprises a permanent magnet coupled to a lower surface of the shuttle, and wherein the system further comprises:

a set of electromagnets;

wherein the permanent magnet is configured to engage with the set of electromagnets to propel the shuttle.

11. An item delivery system comprising:

a shuttle configured to support an item, the shuttle comprising a wheel, wherein the wheel has a first side surface, a second side surface, and a middle portion that together form a v-groove;

a first rail configured to engage the first side surface and the second side surface;

a second rail configured to engage the first side surface and the second side surface, wherein the second rail is separated from the first rail;

a first transition block coupled to the first rail, the first transition block configured to transfer a load of the shuttle from the first side surface and the second side surface to the middle portion of the wheel, wherein the first transition block comprises a base, and an angled blind hole disposed in the base; and

a second transition block coupled to the second rail, the second transition block configured to transfer the load of the shuttle from the middle portion of the wheel to the first side surface and the second side surface of the wheel.

12. The item delivery system of claim 11 , wherein the first transition block comprises:

a first ramp portion having a first incline angle; and

a second ramp portion having a second incline angle that is less than the first incline angle.

13. The item delivery system of claim 12 , wherein the first ramp portion has a first length, and the second ramp portion has a second length that is greater than the first length; and

wherein the first ramp portion has a tapered width.

14. The item delivery system of claim 11 , wherein the shuttle further comprises a permanent magnet coupled to a lower surface of the shuttle, and wherein the system further comprises:

a set of electromagnets;

wherein the permanent magnet is configured to engage with the set of electromagnets to propel the shuttle.

15. A system configured to transport items, the system comprising:

a shuttle configured to support an item, the shuttle comprising a first wheel, wherein the first wheel has a first side surface, a second side surface, and a middle portion that together form a v-groove;

a first rail configured to engage the first side surface and the second side surface;

a second rail configured to engage the first side surface and the second side surface, wherein the second rail is separated from the first rail; and

a first transition block coupled to the first rail, the first transition block configured to transfer a load of the shuttle from the first side surface and the second side surface to the middle portion of the wheel, wherein the first transition block has a length that is equal to or less than a circumference of the first wheel.

16. The system of claim 15 , further comprising:

a second transition block coupled to the second rail, the second transition block configured to transfer the load of the shuttle from the middle portion of the wheel to the first side surface and the second side surface of the wheel.

17. The system of claim 15 , wherein the first transition block is in a first orientation and the second transition block is in a second orientation that is opposite the first orientation.

18. The system of claim 15 , wherein the first rail does not engage the middle portion of the first wheel, and the second rail does not engage the middle portion of the first wheel.

19. The system of claim 15 , wherein the first transition block comprises:

a base; and

an angled blind hole disposed in the base.

20. The system of claim 15 , wherein the first transition block has a length that is equal to or less than a circumference of the first wheel.
