Abstract

The present invention relates to an apparatus for milking an animal comprising a first set of teatcups and a second set of teatcups, said first set of teatcups comprising at least two teatcups of the same size or shape, said second set of teatcups comprising at least two teatcups of the same size or shape, each said teatcups being elongated and comprising a rigid shell and a flexible liner forming a pulsation space, said liner being adapted to receive a teat at one end and to let out extracted milk at a second end. According to the invention the first set of teatcups comprises teatcups of a first size or shape and the second set of teatcups comprises teatcups of a second size or shape, the first size or shape being different from the second size or shape.

Claims

1. An apparatus for milking an animal comprising a first set of teatcups and a second set of teatcups, said first set of teatcups comprising at least two teatcups of the same size or shape, said second set of teatcups comprising at least two teatcups of the same size or shape, characterised in that each of said teatcups is elongated and comprises a rigid shell and a flexible liner forming a pulsation space, said liner being adapted to receive a teat at one end and to let out extracted milk at a second end, the first set of teatcups comprises teatcups of a first size or shape and the second set of teatcups comprises teatcups of a second size or shape, the first size or shape being different from the second size or shape.

2. An apparatus according to claim 1, wherein the liner of said first set of teatcups has a longitudinal extension at the pulsation space, which is different from that of the liner of the second set of teatcups.

3. An apparatus according to claim 1, wherein the shells of the teatcups of said first set of teatcups have a longitudinal extension, which is different from that of the shells of the second set of teatcups.

4. An apparatus according to claim 1, wherein said liner is provided with a thin, lip-like member, defining an opening of a predetermined diameter, a liner of the first set of teatcups having an opening, which is different from that of the liner of the second set of teatcups.

5. An apparatus according to claim 4, wherein said lip-like member has a predetermined flexibility, said flexibility of the liner of the first set of teatcups being different from that of the liner of the second set of teatcups.

6. An apparatus according to claim 1, wherein at least one of said first and second sets of teatcups is provided in a teatcup magazine.

7. An apparatus according to claim 6, wherein said teatcup magazine is provided with a rinsing means.

8. An apparatus according to claim 1, wherein a milk meter is connectible via a valve to a teatcup of the first set of teatcups, respectively, each milk meter being connectible via said valve to a teatcup of the second set of teatcups, respectively, said valve allowing either of a teatcup of the first set of teatcups and a teatcup of the second set of teatcups to be connected to the milk meter, respectively.

9. An apparatus according to claim 1, wherein it further comprises a device for automatically attaching teatcups to the teats of an animal in response to a control means, and an animal identification means associated with said control means, the size of each teat of an animal individual being stored in a memory of said control means, said apparatus being adapted to choose at least one teatcup from either of said first and second sets of teatcups.

10. An apparatus according to claim 9, wherein said device comprises a robot having a robot arm and a gripper for selectively gripping a teatcup from either of the first and the second sets of teatcups.

11. An apparatus according to claim 9, wherein said device comprises a teatcup identification means.

12. An apparatus according to claim 11, wherein said teatcup identification means device comprises a laser reader, each of said teatcups being provided with a bar code.

13. An apparatus according to claim 1, wherein the teatcups of said first set of teatcups are connectible to a first claw and the teatcups of said second set of teatcups are connectible to a second claw.

14. A kit of parts for the apparatus according to claim 1 comprising at least one teatcup of a first size or shape and at least one teatcup of a second size or shape, the first size or shape being different from the second size or shape.

15. A kit of parts for the apparatus according to claim 1 comprising at least one liner for a teatcup of a first size and at least one liner for a teatcup of a second size, the first size being different from the second size.

16. An apparatus for milking an animal comprising at least one set of teat cups, which are elongated and each comprises a rigid shell and a flexible liner forming a pulsation space, said liner being adapted to receive a teat at one end and to let out extracted milk at a second end, characterised in that said set of teat cups comprises at least a first teat cup of a first size or shape and at least a second teat cup of a second size or shape, said first size or shape being different from said second size or shape.

17. An apparatus according to claim 16, wherein said set of teat cups comprises teat cups of a third size and shape, said third first size or shape being different from said first and second size or shape.

18. An apparatus according to claim 16, wherein said set of teat cups comprises teat cups of a fourth size or shape, said fourth size or shape being different from said first, second and third size or shape.

19. An apparatus according to claim 16, wherein said apparatus comprises a first and a second set of teat cups and said first set of teat cups is different from the second set of teat cups.

20. An apparatus according to claim 16, wherein said apparatus comprises a plurality of sets of teat cups, each set has individually sized and shaped teat cups and said teat cups in each individual set of teat cups differ from said teat cups in another set of teat cups.
