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 double grabber mounted on an arm of a robotic attacher, the double grabber comprising:
a first housing part operable to hold a first teat cup; and
a second housing part operable to hold a second teat cup and positioned side-by-side with the first housing part;
wherein the first housing part is operable to pivot downwardly in relation to the second housing part in conjunction with the second housing part attaching the second teat cup to a dairy livestock; and
wherein the second housing part is operable to pivot downwardly in relation to the first housing part in conjunction with the first housing part attaching the first teat cup to the dairy livestock.

2. The double grabber of claim 1 , further comprising a cylinder to pivot the first housing part.

3. The double grabber of claim 1 , wherein the first housing part is operable to pivot independently of the second housing part.

4. The double grabber of claim 1 , wherein:
the first housing part is operable to retract longitudinally in relation to the arm of the robotic attacher in conjunction with the second housing part attaching the second teat cup to the dairy livestock; and
the second housing part is operable to retract longitudinally in relation to the arm of the robotic attacher in conjunction with the first housing part attaching the first teat cup to the dairy livestock.

5. The double grabber of claim 1 , wherein:
the first housing part is provided with a first magnet designed for holding the first teat cup; and
the second housing part is provided with a second magnet designed for holding the second teat cup.

6. The double grabber of claim 5 , wherein the first magnet is installed in a movable fashion in the first housing part.

7. The double grabber of claim 6 , wherein the first magnet is movable substantially in the lengthwise direction of the arm.

8. The double grabber of claim 7 , wherein the first magnet is operable to extend to grab the first teat cup and retract to release the first teat cup.

9. The double grabber of claim 6 , wherein the first magnet is a permanent magnet.

10. The double grabber of claim 1 , wherein the first housing part is operable to retract in the lengthwise direction of the arm.

11. The double grabber of claim 1 , wherein the first housing part is operable to extend in the lengthwise direction of the arm.

12. The double grabber of claim 1 , further comprising a contact member installed between the first and second housing parts and designed to make contact with a rinsing cup.

13. The double grabber of claim 12 , whereby the contact member is designed such that the rinsing cup is substantially positioned in the extension of the arm.

14. The double grabber of claim 1 , further comprising a cleansing tool.

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