PHILLIPS ORMONDE FITZPATRICK Patent and Trade Mark Attorneys 367 Collins Street Melbourne 3000 AUSTRALIA Invention Title: AN IMPLEMENT FOR MILKING ANIMALS Our Ref 579661 POF Code: 1556/253487 The following statement is a full description of this invention, including the best method of performing it known to applicant(s): AN IMPLEMENT FOR MILKING ANIMALS The present application is a divisional application from Australian patent application number 74273/96, the entire disclosure of which is incorporated herein by reference.
The present invention relates to an implement for milking animals, such as cows, comprising at least one milking parlour including at least one milking robot for automatically connecting teat cups to the teats of an animal to be milked, automatically milking this animal, and automatically disconnecting the teat cups from the teats, which implement is provided with at least one detector for 10 determining the position of the teats.
Patent application WO 94/12020 describes detectors constituted by elements for creating an image, in particular by video recording elements, which ;are arranged on both sides of the milking parlour. When arranging such detectors the problem could occur that, on the one hand, the detectors have to be disposed relatively close to the udder of the animals to be milked, while, on the other hand, the distance thereto has to be such that the detectors are prevented from being damaged e.g. because of kicking by the animal to be milked.
According to the invention there is provided an implement for milking animals, including at least one milking parlour including at least one milking robot 20 for automatically connecting teat cups to the teats of an animal to be milked, i automatically milking this animal, and automatically disconnecting the teat cups from the teats, which implement is provided with at least two detectors for determining the position of the teats, wherein at least two of these detectors are constituted by a transmitter-receiver whereby by means of each of these detectors a space sector can be scanned.
Preferably each detector is located within its own housing. By accommodating the detectors in a suchlike housing said detectors are protected in particular against kicking by the animals to be milked. The housing of the detectors is preferably fitted on both sides of the milking parlour, in the floor of said milking parlour, on the floor thereof, or near thereto.
C:\WINWORDTONIABF\DIVISI-1\DV74273DOC Preferably, the detectors can be disposed in the housing so as to be motor drivable about two axes, whereby in a concrete embodiment a detector is movable about a substantially horizontal axis as well as about its own longitudinal axis.
When a laser transmitter and receiver element is used, a housing can be provided with a filter at least letting
C
C:\WINWORD\TONI\BF\DIVISI-1\DI74273DOC through frequencies within the frequency band to which the detector is sensible. This filter can constitute the upper side of the housing. A very solid solution is obtained when the housing is fitted in the floor of the milking parlour and the upper side of the housing is constituted by a dome-shaped element. In order to enable the detector disposed in the housing to function optimally, at least the upper side of the housing will have to be cleaned. For that purpose, the implement is provided with a cleaning device for this housing, in particular a spraying device for the upper side of the housing.
For a better understanding of-the invention and to show how the same may be carried into effect, reference will now be made, by way of example, to the embodiment shown in 15 the accompanying drawings, in which: Figure 1 shows schematically, in plan view, the implement according to the invention; Figure 2 shows schematically a side view of said implement; Figures 3 and 4 show a plan view respectively a longitudinal cross-section of a detector disposed in a housing.
The figures show a milking parlour 1 in which an animal to be milked is marked in dashed lines. The milking 25 parlour 1 is confined by a fencing 2 in which, at one of the longitudinal sides, there is provided an entrance door 3 and an exit door 4. At the front side of the milking parlour a feeding trough 5, constituting part of a (non-shown) automatic feeding system, is fitted to the fencing 2. An animal entering the milking parlour 1 is identified there by means of an animal identification system known per se, constituted by a collar 6, worn by the animal, which collar is provided with a transponder cooperating with a (non-shown) sensor disposed near the feeding trough, which sensor is in connection with the computer system of the implement. As the animal identification system does not constitute part of the invention, said system will not be described in detail. In order better to position the animal in the longitudinal direction, there is mounted at the rear side of the milking parlour, as shown in Figures 1 and 2, a buffer element 7 to be pressed against the rear side of the animal. The implement further comprises a milking robot 8 for automatically connecting teat cups 9 to the teats of an animal to be milked, automatically milking this animal and automatically disconnecting the teat cups 9 from the teats. A suchlike milking robot has been known for some time already in all sorts of embodiments. For automatically connecting the teat cups to the teats of an animal to be milked it is necessary to know the position of the teats of the animal. Although for this purpose there may be used historic data in relation to the teat position, in particular when the animal is accurately positioned in the milking parlour or when the position of the *°So 15 animal in the milking parlour is known, therebesides or even S• in stead thereof, one or more detectors specially provided therefor can be used. In the present embodiment, two detectors are available for determining the position of the teats in three coordinates; these detectors are indicated by the 20 reference numeral 10 (see Figure 3 and These detectors are disposed in an own housing 11, fixedly arranged relative to the milking parlour, which housing is preferably fitted, as indicated in Figure 1, on both sides of the milking parlour 1, in the floor of said milking parlour, on the floor 25 thereof, or near thereto. As indicated in Figures 2 and 4, this housing 11 is incorporated to a considerable extent in the floor of the milking parlour. Although, in this embodiment there can be arranged passive detectors, which can in particular be constituted by an element for creating an image, i.e. more specifically, a video recording element or a video camera, each of these detectors, one of which is represented in Figures 3 and 4, is constituted by a transmitter-receiver and in particular by a laser transmitter and receiver element. The detector shown in Figures 3 and 4 is of the type described in European patent application 0455305.
The description of the detector included therein has to be considered as inserted in the present text. For the purpose of adapting this detector to the function of determining the position of the teats in three coordinates, the detector is mounted in the housing 11 so as to be movable about a substantially horizontal axis 12, as well as about its own longitudinal axis 13. The detector 10 is movably mounted on a mounting element screwed on the bottom of the housing 11. To said mounting element 14 there is fastened a motor 15 which, by means of a belt transmission 16, is capable of turning the detector 10 and having it reciprocate about the axis 12. The detector 10, which is movable about the axis 12, is provided at its lower side with a motor 17 enabling the detector 10 to rotate about its own longitudinal axis 13 and to reciprocate.
The motors 14 and 17 are controlled from the computer system of the implement. This computer system can be supposed to constitute part of the milking robot 8. Under the control of 15 this computer system a space sector can be scanned by the *detector 10. In order to be able to determine the position in three coordinates of at least the animal's teats which, seen in the range of view of the detector, are the foremost ones, the detectors 10 have to be arranged in their housing such S: 20 that the teats are located within the space sector which is scanned by means of the detectors 10. It is noticed that, although it is preferable to dispose the movably mounted detector 10 in the housing 11, it remains possible to dispose the movably mounted detector according to Figures 3 and 4 25 outside a suchlike housing. Also in that case, of course, it will be possible to scan a space sector where the teats are supposed to be located by means of the detectors, and thus to determine the three position coordinates of the teats.
For the purpose of increasing the reliability of the detector, the housing 11 can be provided with a filter at least letting through frequencies within the frequency band to which the detector is sensible. When the detectors are arranged in the floor of the milking parlour or near thereto, this filter can also constitute in a favourable manner the upper side of the housing. In order to optimize the protection of the detectors, the housing, as indicated in Figure 4, comprises a dome-shaped element 18 serving as a cover of the housing 11; said dome-shaped element 18 can also function as a filter for the light incident on the detector. Furthermore, in order not to influence the function of the detectors in an unfavourable manner, the dome-shaped element 18 will have to be cleaned regularly. For that purpose the implement is provided with a cleaning device 19 for the housing 11. In the present embodiment, on both sides of the milking parlour, there is fastened to the fencing 2 a cleaning device 19 constituted by a spraying device, by means of which a cleaning fluid can be sprayed over the upper side of the housing 11, in particular over the dome-shaped element 18 thereof.
The invention is not restricted to the embodiment described and shown in the figures, but also relates to all sorts of modifications thereof, of course, falling within the scope of the following claims.
