Abstract
Disclosed is a mechanical manifold valve for robotic milking that is designed to operate at varying pressures, and which is operated automatically according to the pressure in at least one of the teat cups, such that the pressure in that teat cup influences the operation of the manifold valve, thereby controlling the pressure in at least one additional teat cup.
Claims20
An automatic mechanical manifold valve having an opened configuration and a closed configuration,
- wherein said automatic mechanical manifold valve is coupled to a first group of teat cups and to a second group of teat cups;
- and
- wherein the first group of teat cups and the second group of teat cups are each coupled to:
- a main milk line;
- and
- a vacuum system creating pressure in each of the teat cups of the first group of teat cups and in each of the teat cups of the second group of teat cups;
- and wherein the manifold valve is set:
- to the closed configuration when the pressure in the first group of teat cups is above a predefined pressure value;
- or
- to the opened configuration when the pressure in the first group of teat cups is below said predefined pressure value;
- and wherein
- when the manifold valve is in the closed configuration, the second group of teat cups is essentially disconnected from the main milk line, such that matter cannot flow from the teat cups of the second group of teat cups into the main milk line;
- and
- when the manifold valve is in the opened configuration, the second group of teat cups is essentially connected to the main milk line, allowing the flow of milk from the teat cups of the second group of teat cups to the main milk line.
The automatic mechanical manifold valve according to claim 6, wherein the tension of said spring is adjustable.
A teat cup assembly comprising a first group of teat of teat cups, a second group of teat cups, and an automatic mechanical manifold valve,
- wherein said automatic mechanical manifold valve has a closed configuration and an opened configuration;
- wherein a pressure in said first group of teat cups, or in a chamber coupled to said first group of teat cups, controls said automatic mechanical manifold valve, determining whether said automatic mechanical manifold valve is in the closed configuration or the opened configuration;
- and
- wherein said automatic mechanical manifold valve controls flow from said second group of teat cups to a main milk line, such that in the closed configuration the flow from said second group of teat cups to said main milk line is essentially blocked, while in the opened configuration the flow from said second group of teat cups to said main milk line is essentially free.
A method for controlling milk flow from a second group of teat cups to a main milk line, via an automatic mechanical manifold valve, by a pressure in a first group of teat cups or in a vacuum chamber coupled to said first group of teat cups,
- wherein when said pressure is above a predefined pressure value, said automatic mechanical manifold valve is in a closed configuration, such that matter is essentially blocked from flowing from said second group of teat cups to said main milk line;
- and
- wherein when said pressure is below a predefined pressure value, said automatic mechanical manifold valve is in an opened configuration, such that matter is essentially free to flow from said second group of teat cups to said main milk line.
