DRIVE FOR A SAMPLE CARRIER

Abstract

A rotary plate (1) of a centrifuge (2) having a pivoting plate (3) mounted thereon is provided, to carry out a rotational and/or pivoting movement of the pivoting plate (3) relative to the rotary plate (1). This allows the rotary plate (1) to be drivable by a drive (5) rotationally decoupled from the rotary plate (1).

Claims

1. A rotary plate arrangement of a centrifuge (2), the rotary plate arrangement comprising: a rotary plate; at least one pivoting plate (3) mounted on the rotary plate; wherein at least one of a rotational or pivoting movement (4) of the pivoting plate (3) relative to the rotary plate (1) is adapted to be driven by a drive (5) that is rotationally decoupled from the rotary plate (1).

2. The rotary plate arrangement as claimed in claim 1, wherein the pivoting plate (3) comprises a holder (6) for a sample carrier (7).

3. The rotary plate arrangement as claimed in claim 1, wherein the at least one pivoting plate comprises a plurality of pivoting plates (3) that are connected to one another by a gear (8), and the pivoting plates (3) are synchronously rotatable and/or pivotable.

4. The rotary plate arrangement as claimed in claim 3, further comprising a gear (9) that is adapted to convert a translational movement (10) of the drive (5) into the rotational and/or pivoting movement (4) of the pivoting plates (3).

5. The rotary plate arrangement as claimed in claim 1, further comprising a spindle (11) and a spindle nut (13) arranged on an axis of rotation (D1) of the rotary plate (1), one of said spindle or spindle nut (11, 13) being fixed to the rotary plate (1) and the other of said spindle or spindle nut(11, 13) being rotatable in a direction of rotation (12) of the rotary plate (1).

6. The rotary plate arrangement as claimed in claim 5, wherein the rotational and/or pivoting movement (4) of the pivoting plate (3) is driveable by a rotational movement (4) of the spindle (11) and/or of the spindle nut (13).

7. The rotary plate arrangement as claimed in claim 5, wherein a translational movement (10) of the spindle (11) and/or the spindle nut (13) arranged on the axis of rotation (D1) of the rotary plate (1) is driveable by a translational movement (10) of a drive rod (14) rotationally decoupled from the rotary plate (1).

8. The rotary plate arrangement as claimed in claim 7, wherein the rotational decoupling of the drive (5) from the rotary plate (1) is realized by a rolling bearing (15).

9. The rotary plate arrangement as claimed in claim 1, wherein at least one of the pivoting plate (3) or a sample carrier (7) mounted on a holder (6) of the pivoting plate (3) is heatable.

10. A centrifuge (2) comprising a rotary plate arrangement as claimed in claim 1.

11. A method for rotating and/or pivoting a pivoting plate (3) arranged on a rotary plate (1) of a centrifuge (2), the method comprising driving a rotational and/or pivoting movement of the pivoting plate (3) by a drive (5) that is rotationally decoupled from the rotary plate (1).

12. The method as claimed in claim 11, wherein the rotational and/or pivoting movement of the pivoting plate (3) is driven by a translational movement.

13. The method of claim 12, wherein the translational movement is carried out by a drive rod (14).

14. The method of claim 12, wherein the translational movement is a lifting movement.

15. The rotary plate arrangement of claim 2, wherein an alignment of the pivoting plate (3) determines locking of the sample carrier (7) to the pivoting plate (3).

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The invention will now be described in more detail with reference to an exemplary embodiment, but is not restricted to the exemplary embodiment. Further exemplary embodiments emerge from combining the features of individual or multiple claims with one another and/or with individual or multiple features of the exemplary embodiment.

[0034] In the FIGURES:

[0035] FIG. 1 shows a schematic illustration of a rotary plate according to the invention.

DETAILED DESCRIPTION

[0036] FIG. 1 shows schematically a rotary plate 1 according to the invention, which can be used with a centrifuge 2. Pivoting plates 3 are mounted on the rotary plate 1. A rotational movement 4 of the pivoting plates 3 relative to the rotary plate 1 can be driven by a drive 5 rotationally decoupled from the rotary plate 1. The pivoting plates 3 have a holder 6 for a sample carrier 7. The pivoting plate 3 and/or a sample carrier 7 mounted on a holder 6 of a pivoting plate 3 can be heatable. The pivoting plates 3 are connected via a gear 8, which is in the form of a toothed gear 9.

[0037] The gear 8 is designed in such a way that a translational movement 10 of the drive 5 leads to a rotational movement 4 of the pivoting plates 3. A spindle 11 which is fixed to the rotary plate 1 and a spindle nut 13 which is rotatable in the direction of rotation 12 of the rotary plate 1 are arranged on the axis of rotation D1 of the rotary plate 1. The gear is further designed in such a way that a rotational movement 4 of the pivoting plates 3 can be driven by a rotational movement 4 of the spindle nut 13. The rotational movement 4 of the spindle nut 13 is caused by an axial translational movement 10 of the spindle nut 13, which is driven by a translational movement 10, in this case a lifting movement, of a drive rod 14 rotationally decoupled from the rotary plate 1.

[0038] The rotary decoupling of the drive 5 from the rotary plate 1 is realized by a rolling bearing 15. The rolling bearing 15 is in the form of an axial ball bearing 16 with an inner ring 17, an outer ring 18 and balls 19.
