Definitions

  • the present invention relates to a process and an apparatus for automated milking of sheep and goats and small ruminants in general.
  • Known milking devices include a vacuum source, a milking unit provided with milking tubes to be attached to the animals' teats, a pulser, and a milk manifold.
  • the apparatus is connected to a series of pipes that form a vacuum circuit (connected to a vacuum pump) and a circuit for the milk.
  • the milking tubes are made of a rigid material and contain an internal sheath, or teat cup, made of rubber or of a similar flexible material, which creates a leak-tight gap or interspace between sheath and tube.
  • the interior of the teat cup is always connected to the vacuum, while the gap or interspace is always connected to the pulser.
  • the gap is alternately connected to the vacuum circuit and the atmosphere, so as to have the teat perform the required milking action.
  • This aim has been achieved with the present invention, which relates to a process of milking sheep, goats, and small ruminants in general, by means of an apparatus comprising a milking unit, a manifold, a pulser and means of connection to a vacuum source, characterized in that it comprises a step in which said milking unit is automatically removed and a step in which said apparatus is idle, said milking unit and said manifold being kept at atmospheric pressure during said steps.
  • Preferably automatic removal is done by pre-setting the amount of time that the pulser will be operated, then bringing the milking unit and manifold to atmospheric pressure level after the pulser is deactivated, and then removing the milking unit; that is, detaching the tubes from the animal's teats only after the milking unit has been brought to atmospheric pressure level.
  • the invention relates an apparatus for milking sheep, goats, and small ruminants in general, including a milking unit to be connected to the animal teats, a manifold, a pulser, and means of connecting same to a vacuum source, characterized in that it further comprises: a means of activating said pulser for a pre-set amount of time; a means of connecting said milking unit and said manifold to said vacuum source and to the atmosphere; and a means of automatically removing said milking unit from said teats.
  • the apparatus includes three timers to regulate the operation time of the pulser, the removal mechanism, and the connection means between the vacuum and the collector manifold.
  • the means of automatically removing the milking unit comprises a saddle that is moveable between an idle position and a working position, and a pivot that rotates as the saddle is moved. Manifold and milking unit are mounted on this pivot and they are rotated and moved simultaneously.
  • the milking unit normally includes only two milking tubes.
  • Another object of the invention is a milking plant comprising a plurality of apparatuses according to the invention.
  • the invention has a number of advantages over the state of the art. Milking time is drastically reduced: to milk 180 animals using the process and apparatus of the invention, it takes about 55-60 minutes, whereas traditional milking takes about 1 hour and 45 minutes. Moreover, only one operator is required.
  • Another advantage is that the milking unit tubes are gently brought to atmospheric pressure before they are detached from the animal's teats; in this way, the animal's udder is unharmed and the risk of mastitis is greatly reduced.
  • - Fig.l is a diagram of the apparatus according to the invention.
  • - Fig.2 is a diagram that shows the position of the timers with respect to some of the parts of the apparatus;
  • - Fig.3 is a perspective view of the milking tube removal mechanism according to the invention;
  • FIG. 4 is schematic sectional and local views of the mechanism described in Fig.3;
  • - Fig.6 is a plan view of a construction detail of the mechanism described above;
  • Fig.7 is a front view of the mechanism described in Figs. 4 and 5.
  • Fig.l schematically shows an apparatus 1 , according to the invention, comprising milking unit 2, collector manifold 3, a duct 5 for connection to vacuum source 12 (Fig.2), and duct 6 for the milk.
  • Manifold 3 is of a type known in milking technology, preferably a horizontal type, and is connected to two milking tubes 7 by means of semi-rigid tubing 8 - that is, a tubing which allows the milking tubes 7 to move freely, but which sustains them at the same time.
  • Manifold 3 is also provided with valve 22, that is a valve normally open to allow a reduced amount of air to enter the manifold when this is connected to vacuum source 12 and is at a reduced pressure, the purpose of valve 22 is to enable the milk sucked through ducts 8 into manifold 3 to further flow into milk duct 6.
  • Manifold 3 is mounted on a saddle 9 that moves axially from an idle position to a working, or milking, position. More specifically, the manifold is engaged with pivot 10, that is rotatable (Figs.3-5) with disk 11.
  • the invention apparatus comprises pulser 4 connected to manifold 3 and milking unit 2, to operate the teats, or sheaths, within tubes 7. Every apparatus will have its own pulser.
  • Pulser 4 is coupled with first timer T1 , that activates the pulser for a pre-set amount of time: said time is normally calculated in relation to the type of animals to be milked. For instance: for sheep, an effective milking time of 60 seconds is considered appropriate; the time that will be set with the timer, however, is longer - approximately 150 seconds - in order to take into account the down-time required to manually attach the milking tubes 7 to the sheep's teats.
  • solenoid valve 13 and timer T3 are provided.
  • the solenoid valve is operated through control panel 14 (Fig.l ) and, as is explained in greater detail below, through timer T3, in one of the steps of the invention process.
  • Control panel 14 also provides means 14a to cut out, on request, timer Tl to operate in totally manual mode. This option is used when the animals to be milked have udder problems and require a personalized milking.
  • Figures 3 to 6 show, in greater detail, the removal mechanism, which comprises sliding saddle 9 mounted on a base 15. Saddle 15 is movable in the direction of arrow FI , by means of pneumatic piston 16, from an idle position (Fig.4) to a working position (Fig.5). As shown, the idle position is corresponding to the position obtained once the piston has been activated.
  • Piston 16 is operated by feeding air into cylinder 17 through line 17a, which is extending to control panel 14 (Fig.l ). Air flow through line 17a to cylinder 17 is controlled by solenoid valve 9a.
  • Elastic means are provided to move piston 16 back to the position shown in Fig.5 once the air sent to the cylinder is cut off.
  • the position of fig. 5 is the working position of the milking unit.
  • saddle 9 is manually movable from the position shown in Fig.4 to the position shown in Fig.5.
  • pivot 10 is mounted integral with a disk made of two pieces fixed to each other and sitting on bearings 19. Pivot 10 extends through rotating disk 1 1 and engages second disk 18, which has a second pivot 20; the end portion of pivot 20 is housed in race 21.
  • the race 21 has a mixed line movement (Fig.6), with an inflexion point, so as to cause second pivot 20 to shift during the translation of the saddle and the consequent rotation of disk 18, pivot 10 and disk 1 1.
  • the rotation angle is 90°.
  • the milking unit is retracted in relation to the milking point, and rotated 90° to the A-A center line of the saddle.
  • pivot 10 rotates together with milking unit 2, which is then aligned with the saddle's center line.
  • milking unit 2 and pivot 10 are rotated in the opposite direction.
  • disk 1 1 and pivot 10 can be rotated with other systems used in existing technology: using racks, for example.
  • the process according to the present invention provides for interrupting the operation of the pulser and returning milking unit 2 and manifold 3 to the atmospheric pressure level; after these operations, the saddle 9 is moved, removing the milking unit, whose tubes have by this time detached from the milked animal's teats, to bring the milking unit to ⁇ rotated position, retracted with respect to the milking point.
  • Effective milking is stopped when the desired milking time that has been pre-set on the timer (Tl ) has lapsed. This contrasts with known art, where effective milking stops when milk flow through the relative line (duct 8, for example) has ceased.
  • the apparatus is in the following condition: the pulser 4 is switched off, the air solenoid valve (that is, the valve that feeds air to cylinder 15) is on and has moved piston 16 to its protruding position (fig.4). Piston 16 has shifted the saddle into a position retracted from the milking point, with the milking unit 2 rotated approximately 90°.
  • the vacuum solenoid valve 13 is off and manifold 3 and milking unit 2 are at atmospheric pressure.
  • Pulser 4 and timer Tl are switched on; Tl controls the effective operating time of the pulser and, usually, the timer is pre-set to have the pulser operate for a longer time than the effective milking time, in order to cover the time required to attach (manually) the milking tubes 7 to the animals' teats.
  • Air solenoid valve 9a is deactivated, thereby moving saddle 9 and the milking group to the working position.
  • the vacuum solenoid valve (13) is now activated and the operator attaches milking tubes 7 to the teats of the animal thas is to be milked. Then, the apparatus carries out milking operations for the pre-set amount of time as controlled by timer Tl ; that is, until the pulser is stopped. When timer Tl switches off, the pulser stops and vacuum solenoid valve 13 is deactivated.
  • the manifold 3 is gradually brought to atmospheric pressure, by admitting atmospheric air through valve 22 of manifold 3; the main function of this valve is to feed a reduced flow of air to the manifold to enable milk to flow through manifold 3 to duct 6 during the milking step, i.e. when vacuum is applied to the milking unit.
  • timer T2 is activated. Timer T2 delays the activation of air solenoid valve 9a long enough (e.g. for 4 seconds) to bring the manifold and the milking unit to atmospheric pressure.
  • the milking group is at atmospheric pressure level and milking tubes 7 have detached from the milked animal's teats.
  • the air solenoid valve 9a is activated, thereby moving the milking group to the idle position; the timer T3 is switched on, which activates again vacuum solenoid valve 13 for a short period of time (e.g. 2-4 seconds) in order to remove any remaining milk left in ducts 8 and manifold 3.
  • a short period of time e.g. 2-4 seconds
  • the apparatus is once again in the idle step, and remains in said condition until it is applied to a new animal to be milked.
