DESCRIPTION

EMPTY CUTTING COMMAND FOR ORDER FACILITIES Technical sector

The present invention is related to automatic sorting facilities, proposing a vacuum cutting control for said facilities, which facilitates the user's action to momentarily cut the vacuum when the teats are removed from the teats of the udders, maintaining adequate conditions of effectiveness of that function of cutting the vacuum.

State of the art

Automatic milking facilities include elements called teat cups, which for milking are arranged in the teats of the udders, applying a pulsed vacuum in said teats that makes them work to extract the milk from the application udder and send it to a tank receiver through a hose connected to the liner, through which the actuator vacuum of the liner is applied.

When the milk is finished extracting from the udder that is ordered, the nipples must be removed from the nipples, which if done with the vacuum acting on the nipples, the nipple undergoes a tiron and air and dirt can enter the sphincter , which is very harmful because it contributes to the appearance of the pathology called mastitis.

To avoid this problem, a throttle element is arranged in the conduction hose of the milk that is connected to each liner, which allows the vacuum to be cut when the nipple has to be removed from the application nipple, conventionally using a rotary wrench for said function , which to be operated requires that the user have to use both hands since the key has to be held at the same time as it is operated, so that with the effort of actuation of the key, the conduction hose of the milk in which it is incorporated.

Object of the invention

According to the invention, a command is proposed for the function of cutting the vacuum in the

milk conduction hoses that are connected to the nipples in automatic milking facilities, this command being carried out with a formation that allows its operational operation in an effective way with only one hand, facilitating the action that the user has to perform.

This control object of the invention comprises a tubular body, with respect to which a sealing element is incorporated, in a disposition capable of moving perpendicular to the longitudinal direction of the tubular body, between an opening position and a closing position of the inner duct of said tubular body, the sealing element being pushed by an actuating spring towards the opening position of said inner duct of the tubular body.

The sealing element is formed by a truncated conical body to which axially a carrier rod is attached that passes through a retention cap that keeps the truncated conical body in a free disposition moving between a forward position and a reverse position, which They correspond to the closing and opening of the inner duct of the tubular body, the carrier rod joining at the other end to an outer cap which is pushed by the actuating spring of the sealing element.

Thus, under normal conditions the control is kept with the inner duct of the tubular body open, since the actuating spring keeps the sealing element moved towards the opening position of said inner duct; but by pressing on the outer cap, an action is achieved against the thrust of the actuating spring, with consequent displacement of the sealing element towards the closing position of the inner duct of the tubular body of the control, said action being able to be performed with one hand, pressing the command between the fingers and the palm of the hand.

Therefore, the manipulation to close the control is very simple and the user only has to use one hand, while the opening is produced by itself thanks to the action of the actuating spring when it stops pressing on the outer cap, since then the drive spring brings the sealing element to the opening position of the inner duct, which makes this command an advantageous application for the function of closing the vacuum in the milk conduction hoses connected to the teat cups. the milking facilities, acquiring a preferential character with respect to the conventional elements that are used for said function.

Detailed description of the invention

The object of the invention relates to a command for cutting vacuum in milk hoses (1) of milking lids (2), as seen in Figure 5, which facilitates the cutting of the vacuum in the hose of milk (1) for application when the corresponding nipple (2) has to be removed from the nipple (3) in which it has been used in a milking operation.

The recommended control comprises a tubular body (4) which has two extreme openings (5) and (6) for intercalated coupling in the application milk hose (1), also having a perpendicular outlet (7) in a middle area, in correspondence with which a closing seat (9) is defined in the inner duct (8) of said tubular body (4).

In relation to the seat (9), a sealing element (10) is formed, formed by a truncated conical body in reciprocal correspondence with said seat (9), said sealing element (10) being capable of displacement between a fitting position in the seat (9) closing the inner duct (8) of the tubular body (4) and a retracted housing position at the outlet (7) leaving open the passage through said inner duct (8) of the tubular body (4).

The outlet (7) is closed with a cover (11) that holds the sealing element (10)

inside said outlet (7), passing through the aforementioned cover (11) a rod (12) that at one end is attached to the sealing element (10) and at the other end joins an outer cap (13 ), which is pushed by a spring (14) in the direction of bringing the sealing element (10), by means of the rod (12) to the retracted position in which it leaves 5 open the passage through the inner duct (8) .

With this, arranging the control in a milk hose (1) associated with a milking liner (2), when the liner (2) has to be removed from the application nipple (3) after finishing the milking, by means of the The control can be easily cut in the 10 milk hose (1) the vacuum of the liner (2), to prevent the action of the vacuum from damaging the nipple (3) by uncoupling it from the liner (2).

For that cutting action of the vacuum in the application milk hose (1), only the outer cap (13) has to be pressed against the spring (14), to bring the sealing element 15 (10) to the position of fit into the seat (9), as seen in figure 4, which can be done with one hand, resting the tubular body (4) on the palm of the hand and pressing with the fingers on the outer cap (13) or vice versa, resulting in that action of cutting the vacuum very easy to perform.

20 Once the nipple (2) of the nipple (3) is uncoupled, it is only necessary to stop pressing on the outer cap (13), so that it is pushed by the spring (14) returns to the sealing element (10) to the position of housing at the exit (7) again leaving the passage through the inner duct (8) open for the vacuum to actuate the liner (2) for a new milking action on another nipple (3).
