Abstract

Transfer wheel (1) for transferring objects (40, 41) comprises at least a seat module (3). The seat module comprises a seat (2) located at the peripheral face of the transfer wheel and adapted for accommodating an object on the seat. The at least one seat module is a resilient seat module, wherein a position of the seat of the seat module is adaptable in radial direction of the transfer wheel. Also provided is a method for transferring objects.

First claim

The invention claimed is:

1. A method for transferring capsules comprising an in-line adaption of a radial position of a capsule in a seat of a transfer wheel, comprising:
providing a transfer wheel comprising a seat for receiving and accommodating a capsule;
receiving a first capsule on the seat in a receiving location, the first capsule having a first size;
transferring the first capsule to a transfer location and releasing the first capsule at the transfer location;
receiving a second capsule on the seat in the receiving location, the second capsule having a second size, the second size being different to the first size; and
adapting the radial position of the seat such that a maximum radial extension of the transfer wheel defined by an outermost extension of the capsule on the seat is the same for each of the first or second capsule accommodated on the seat in at least one of the receiving location or the transfer location; therein adapting the position of the seat by compressing or expanding a resilient seat module comprising the seat, thereby compressing the seat module itself or pushing back the seat module by compressing a module support;
wherein, the transfer wheel comprises at least a seat module, the seat module comprising a seat located at the peripheral face of the transfer wheel and adapted for accommodating a capsule on the seat, wherein the at least one seat module is an elastically mounted resilient seat module or an elastically compressible resilient seat module, wherein a position of the seat of the seat module is adaptable in radial direction of the transfer wheel, and wherein the seat is a cup-shaped recess in the seat module.

2. The method according to claim 1 , wherein the method comprises:
compressing the resilient seat module by pushing the first or second capsule into the direction of the seat.

3. The method according to claim 1 , wherein the method comprises:
compressing the resilient seat module with a force smaller than a crushing force of the first capsule and of the second capsule.

4. The method according to claim 1 , wherein the method comprises:
compressing the resilient seat module with a force between 1 Newton and 10 Newton.

5. The method according to claim 1 , wherein the first capsule and the second capsule have a spherical, ellipsoidal, or lentil shape.

6. The method according to claim 1 , wherein at least one of the first or second capsule is a capsule containing a liquid.

7. The method according to claim 1 , wherein a compression force of the resilient seat module is between 1 Newton and 10 Newton.

8. The method according to claim 1 , wherein a seat diameter of a seat is between 1 millimeter and 8 millimeter.

9. The method according to claim 1 , comprising a central orifice and at least a passage in communication with the central orifice and the peripheral face of the transfer wheel, the transfer wheel further having a vacuum port in communication with the seat via the at least one passage for applying suction to the seat.

10. The method according to claim 1 , comprising a plurality of seat modules, each seat module of the plurality of the seat modules comprising a seat for accommodating a capsule on the seat.

11. The method according to claim 1 , wherein the seat module is removably mounted in a seat module cavity.

12. An apparatus for transferring capsules-according to a method for transferring capsules comprising an in-line adaption of a radial position of a capsule in a seat of a transfer wheel, comprising:
providing a transfer wheel comprising a seat for receiving and accommodating a capsule;
receiving a first capsule on the seat in a receiving location, the first capsule having a first size;
transferring the first capsule to a transfer location and releasing the first capsule at the transfer location;
receiving a second capsule on the seat in the receiving location, the second capsule having a second size, the second size being different to the first size; and
adapting the radial position of the seat such that a maximum radial extension of the transfer wheel defined by an outermost extension of the capsule on the seat is the same for each of the first or second capsule accommodated on the seat in at least one of the receiving location or the transfer location; therein adapting the position of the seat by compressing or expanding a resilient seat module comprising the seat, thereby compressing the seat module itself or pushing back the seat module by compressing a module support;
wherein, the apparatus comprises a transfer wheel comprising at least a seat module, the seat module comprising a seat located at the peripheral face of the transfer wheel and adapted for accommodating a capsule on the seat, wherein the at least one seat module is an elastically mounted resilient seat module or an elastically compressible resilient seat module, wherein a position of the seat of the seat module is adaptable in radial direction of the transfer wheel, and wherein the seat is a cup-shaped recess in the seat module.

13. The apparatus according to claim 12 , wherein the method comprises:
compressing the resilient seat module by pushing the first or second capsule into the direction of the seat.

14. The apparatus according to claim 12 , wherein the method comprises:
compressing the resilient seat module with a force smaller than a crushing force of the first capsule and of the second capsule.

15. The apparatus according to claim 12 , wherein the method comprises:
compressing the resilient seat module with a force between 1 Newton and 10 Newton.

16. The apparatus according to claim 12 , wherein the first capsule and the second capsule have a spherical, ellipsoidal, or lentil shape.

17. The apparatus according to claim 12 , wherein at least one of the first or second capsule is a capsule containing a liquid.
