Abstract

A beverage system for making a beverage based on ingredients in a capsule has a conveying carriage with a capsule carrier, a threaded spindle extending inside a housing of the beverage system and having a drive nut connected to the capsule carrier. A stop element is arranged on the threaded spindle at an ejection position for blocking movement of the drive nut along the threaded spindle. A motor rotates the threaded spindle in a first direction of rotation, in order to move the capsule carrier to a processing position, where a beverage is made based on the ingredients in a capsule; in order to move the capsule carrier further along the threaded spindle to an ejection position; and in order to rotate the capsule carrier at the ejection position about the threaded spindle to eject the capsule from the capsule carrier.

First claim

The invention claimed is:

1. A beverage system for making a beverage based on ingredients in a capsule, the beverage system comprising:
a conveying carriage having a capsule carrier for receiving the capsule, said conveying carriage being movable on a housing wall of the beverage system together with said capsule carrier out of a housing of the beverage system or into the housing of the beverage system;
a threaded spindle extending inside the housing of the beverage system the housing perpendicular to the housing wall, and a drive nut connected to said capsule carrier;
a stop element disposed on said threaded spindle at an ejection position, said stop element being disposed to block a movement of said drive nut along said threaded spindle; and
a motor configured to rotate the threaded spindle in a first direction of rotation, in order to:
move said capsule carrier along said threaded spindle into the housing of the beverage system to a processing position at which the beverage is made based on the ingredients in the capsule placed in said capsule carrier;
move said capsule carrier further along said threaded spindle to the ejection position; and
rotate said capsule carrier at the ejection position about said threaded spindle to eject the capsule from said capsule carrier.

2. The beverage system according to claim 1 , wherein said conveying carriage has a carriage front which is configured to close an opening in the housing wall for said conveying carriage and for said capsule carrier when said conveying carriage is located with said capsule carrier at the processing position.

3. The beverage system according to claim 2 , wherein:
said conveying carriage comprises at least two carrier rails configured to bear said capsule carrier; and
said conveying carriage is releasably connected via one or more releasable couplings to said capsule carrier.

4. The beverage system according to claim 3 , wherein said releasable couplings are magnetic and/or spring-mounted couplings.

5. The beverage system according to claim 1 , wherein:
said conveying carriage and said capsule carrier are moved together along said threaded spindle between an extended state of said conveying carriage and the processing position; and
said capsule carrier is moved along said threaded spindle without said conveying carriage between the processing position and the ejection position.

6. The beverage system according to claim 1 , further comprising a torsion spring configured to push said capsule carrier onto said conveying carriage.

7. The beverage system according to claim 6 , wherein:
the beverage system comprises a support rail running along said threaded spindle; and
said torsion spring is configured to be supported on said support rail in order to push said capsule carrier onto said conveying carriage along an entire distance between an extended state of said conveying carriage and the ejection position.

8. The beverage system according to claim 1 , wherein said motor is configured to rotate said threaded spindle in a second direction of rotation to rotate said capsule carrier back around said threaded spindle onto said conveying carriage.

9. The beverage system according to claim 1 , wherein:
said motor is configured to rotate the threaded spindle in a second direction of rotation,
to move said capsule carrier along said threaded spindle from the ejection position to the processing position; and
to move said capsule carrier and said conveying carriage along said threaded spindle from the processing position further into an extended state of said conveying carriage out of the housing.

10. The beverage system according to claim 1 , wherein:
said capsule carrier is rotated from a first side of said threaded spindle to an opposing second side of said threaded spindle for ejecting the capsule; and
the beverage system further comprises a collection container for receiving the capsule at the ejection position on the second side of the threaded spindle.

11. The beverage system according to claim 10 , wherein said
capsule carrier is rotated from the first side of said threaded spindle to the opposing second side by an angle of between 160° and 200°.

12. The beverage system according to claim 1 , wherein:
said capsule carrier is fastened to a carriage front of said conveying carriage by way of a releasable first coupling; and
said first coupling is configured to be released when an object is trapped between said carriage front and said housing wall, while said capsule carrier is moved by said motor into the housing.

13. The beverage system according to claim 12 , wherein:
said capsule carrier is fastened to said drive nut by way of a second coupling;
said capsule carrier includes a capsule receiver for receiving the capsule; and
said second coupling is configured to release when the object, which is disposed in said capsule receiver and which protrudes over said capsule receiver, is pushed against said housing wall, while the capsule carrier is moved by said motor into said housing.

14. The beverage system according to claim 13 , wherein:
said capsule carrier is fastened to said drive nut by way of a third coupling; and
said third coupling is configured to release when a carriage front of said conveying carriage is pushed against the object, while the capsule carrier is moved with said conveying carriage by said motor out of the housing.

15. The beverage system according to claim 14 , wherein:
said capsule carrier is connected to said drive nut via a connecting piece;
said second coupling is configured to releasably connect said capsule carrier to said connecting piece; and
said third coupling is configured to releasably connect said connecting piece to said drive nut.

16. The beverage system according to claim 15 , wherein
the capsule carrier has a first guide rail which extends parallel to the threaded spindle and on which the connecting piece is movably mounted; and
the drive nut has a second guide rail which extends parallel to the threaded spindle and on which the connecting piece is movably mounted.

17. The beverage system according to claim 1 , wherein:
said capsule carrier is fastened to said drive nut by way of a coupling;
said capsule carrier includes a capsule receiver for receiving a capsule; and
said coupling is configured to release when an object, which is disposed in said capsule receiver and which protrudes over said capsule receiver, is pushed against said housing wall, while the capsule carrier is moved by said motor into said housing.

18. The beverage system according to claim 1 , wherein:
said capsule carrier is fastened to said drive nut by way of a coupling; and
said coupling is configured to release when a carriage front of said conveying carriage is pushed against an object, while the capsule carrier is moved with said conveying carriage by said motor out of the housing.
