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. Double grabber mountable onto an arm of a robotic attacher for applying teat cups to an udder of an animal, the double grabber comprising:
a first housing part provided with a first magnet designed for holding a first teat cup;
a second housing part, installed substantially in a horizontal plane adjacent to the first housing part, provided with a second magnet designed for holding a second teat cup;
whereby each housing part is operable to pivot separately from each other in a vertical direction around a horizontal axis.

2. Double grabber according to claim 1 , further comprising a cylinder to pivot the first housing part.

3. Double grabber according to claim 1 , further comprising a contact member installed between the first and second housing parts designed to make contact with a rinsing cup.

4. Double grabber according to claim 3 , whereby the contact member is designed such that the rinsing cup is substantially positioned in the extension of the arm.

5. Double grabber according to claim 1 , further comprising a cleansing tool.

6. Double grabber according to claim 1 , wherein the first housing part further comprises a moon-shaped contact member.

7. Double grabber according to claim 1 , whereby the magnet comprises a permanent magnet installed in a movable fashion in or at the first housing part.

8. Double grabber according to claim 7 , whereby the permanent magnet is movable substantially in the lengthwise direction of the arm.

9. Double grabber according to claim 7 , whereby the permanent magnet is operatively connected with a first drive for moving the magnet inside the first housing part.

10. Double grabber according to claim 1 , whereby at least one of the housing parts is provided with a sliding mechanism designed to pull back the housing part in the lengthwise direction of the arm.

11. Double grabber according to claim 10 , whereby the sliding mechanism is activated in conjunction with at least one of the housing parts pivoting about the horizontal axis.
