Abstract

This invention is related to a double grab, its rinsing cup and milking machine provided therewith, and the method for automatically applying teat cups to the teats of an udder of an animal to be milked. The double grab, according to the invention, includes: —a first housing part provided with a first magnet designed to hold a first teat cup; —a second housing part, installed substantially in a horizontal plane next to the first housing part, provided with a second magnet designed to hold a second teat cup whereby each housing part is provided with separate pivoting means that can be activated and is designed to make the related housing part pivot around a pivoting axis which in use, extends substantially in a horizontal direction, substantially in a widthwise direction of the arm.

First claim

The invention claimed is:

1. A method for operating a double grabber mounted on an arm of a robotic attacher, the method comprising:
holding a first teat cup using a first housing part of the double grabber;
holding a second teat cup using a second housing part of the double grabber, wherein the second housing part is positioned side-by-side with the first housing part;
attaching the first teat cup to the dairy livestock using the first housing part; and
pivoting downwardly the second housing part in relation to the first housing part in conjunction with the first housing part attaching the first teat cup to the dairy livestock;
attaching the second teat cup to a dairy livestock using the second housing part; and
pivoting downwardly the first housing part in relation to the second housing part in conjunction with the second housing part attaching the second teat cup to a dairy livestock.

2. The method of claim 1 , wherein pivoting the first housing part comprises using a cylinder.

3. The method of claim 1 , wherein pivoting the first housing part is performed independently of pivoting the second housing part.

4. The method of claim 1 , further comprising:
retracting the second housing part longitudinally in relation to the arm of the robotic attacher in conjunction with attaching the first teat cup to the dairy livestock using the first housing part; and
retracting the first housing part longitudinally in relation to the arm of the robotic attacher in conjunction with attaching the second teat cup to the dairy livestock using the second housing part.

5. The method of claim 1 , further comprising:
holding the first teat cup using a first magnet associated with the first housing part; and
holding the second teat cup using a second magnet associated with the second housing part.

6. The method of claim 5 , wherein the first magnet is movable substantially in the lengthwise direction of the arm.

7. The method of claim 6 , further comprising extending the first magnet to grab the first teat cup and retracting the first magnet to release the first teat cup.

8. The method of claim 5 , wherein the first magnet is a permanent magnet.

9. The method of claim 1 , further comprising retracting the first housing part in the lengthwise direction of the arm.

10. The method of claim 1 , further comprising extending the first housing part in the lengthwise direction of the arm.

11. The method of claim 1 , further comprising contacting a rinsing cup between the first and second housing parts of the double grabber.

12. The double grabber of claim 1 , wherein the first housing part further comprises a moon-shaped contact member.
