Abstract

An articulated sample rack apparatus is disclosed. In one aspect, the articulated sample rack apparatus has a plurality of coupled rack components wherein at least some of the rack components have a receptacle having a bottom to receive a sample container, the rack having free ends and at least one hinge allowing articulation between at least some of the rack components. Conveyor systems and methods to convey sample racks are provided, as are other aspects.

First claim

What is claimed is:

1. An articulated sample container rack apparatus, comprising:
a plurality of coupled rack components, at least some of the coupled rack components having a receptacle configured and adapted to receive a sample container, the receptacle including a bottom, the plurality of coupled rack components having first and second free ends, and at least one hinge allowing relative rotation between at least some of the rack components, wherein the at least one hinge comprises a first part and a second part, and at least one of the coupled rack components comprises or is coupled to both the first part and the second part each fixedly positioned relative to each other without an intervening third part connected between and to the first part and the second part to form the at least one hinge.

2. The rack apparatus of claim 1 , wherein a number of rack components between the first and second free ends in the sample rack apparatus is 15 or less.

3. The rack apparatus of claim 1 , wherein a number of rack components between the first and second free ends in the sample rack apparatus is between 3 and about 10.

4. The rack apparatus of claim 1 , wherein a number of rack components in the sample rack apparatus is between 3 and 7.

5. The rack apparatus of claim 1 , wherein each of the rack components are individually rotatable by 360 degrees or more.

6. The rack apparatus of claim 1 , wherein at least one of the at least one hinge is offset from a location of the receptacles.

7. The rack apparatus of claim 1 , wherein the at least one hinge is substantially aligned with a location of a receptacle.

8. The rack apparatus of claim 1 , wherein the at least one hinge comprises:
a plurality of links coupled to each of the rack components.

9. The rack apparatus of claim 8 , comprising:
end links and spacers coupled to each end rack component of the rack components.

10. The rack apparatus of claim 8 , comprising:
retainers coupled to each of the rack components, the retainers coupled to the rack components to restrain vertical motion of the plurality of links relative to the rack components, yet allow rotation of the rack components relative to the plurality of links.

11. The rack apparatus of claim 1 , comprising:
a component-to-component articulation angle capability of at least 15 degrees.

12. An articulated sample container rack apparatus, comprising:
a plurality of rack components having a total number of between 3 and about 10, at least some of the rack components having a receptacle adapted to receive a sample container, wherein the receptacle includes a sidewall and a bottom;
link sets connected to the rack components at first and second vertically-spaced locations, wherein a first link of a link set at the first vertically-spaced location is fixedly positioned relative to a second link of the link set at the second vertically-spaced location without having an intervening link part connected between and to the first link and the second link; and
retainers coupled to each of the rack components to restrain vertical motion of the link sets relative to the rack components, and yet allow rotation of the rack components relative to the link sets.

13. A sample container rack conveyor system, comprising:
a track formed between a first wall and a second wall, at least one of the walls comprising a moveable wall having cleats extending into the track; and
an articulated sample container rack adapted to be moved along the track by the moveable wall, the articulated sample container rack having a plurality of coupled rack components, at least some of the coupled rack components having a receptacle adapted to receive a sample container, the plurality of coupled rack components having first and second free ends, and at least one hinge allowing articulation between at least some of the coupled rack components, wherein the at least one hinge comprises a first part and a second part, and at least one of the coupled rack components comprises or is coupled to both the first part and the second part each fixedly positioned relative to each other without an intervening third part connected between and to the first part and the second part to form the at least one hinge.

14. The sample container rack conveyor system of claim 13 , wherein the moveable wall comprises an endless belt and the cleats are formed along the endless belt.

15. The sample container rack conveyor system of claim 14 , wherein the cleats engage spaces between adjacent rack components along the moveable wall.

16. The sample container rack conveyor system of claim 15 , further comprising a track corner wherein the cleats disengage the spaces between the rack components in the track corner.

17. The sample container rack conveyor system of claim 13 , further comprising a turntable configured to engage at least some of the rack components at a track corner.

18. The sample container rack conveyor system of claim 17 , wherein the turntable comprises indentations adapted to receive a bottom of at least some of the rack components.

19. The sample container rack conveyor system of claim 13 , wherein the track comprises a stationary floor.

20. A method of conveying a sample rack, comprising:
providing an articulated sample container rack, the articulated sample container rack having a plurality of coupled rack components, at least some of the coupled rack components having a receptacle adapted to receive a sample container, the plurality of coupled rack components having first and second free ends, and at least one hinge allowing articulation between at least some of the rack components, wherein the at least one hinge comprises a first part and a second part, and at least one of the coupled rack components comprises or is coupled to both the first part and the second part each fixedly positioned relative to each other without an intervening third part connected between and to the first part and the second part to form the at least one hinge; and
moving the flexible sample container rack along a track with a moveable wall.

21. The method of claim 20 , further comprising:
moving the articulated sample container rack along the track with the moveable wall and a secondary moveable wall.

22. The method of claim 20 , further comprising:
moving the moveable wall and a secondary moveable wall or moveable member at different rates to spin at least some of the rack components.

23. The method of claim 20 , further comprising:
providing the moveable wall with cleats that disengage the articulated sample container rack in a track corner.

24. The method of claim 20 , further comprising:
moving the articulated sample container rack around a track corner on a turntable.
