Description

147811147811

Opfindelsen angår et apparat til hævning og sænkning af et pattekoppesæt i en malkemaskine, hvilket apparat omfatter en med vacuum arbejdende, pneumatisk stempel-cylinderenhed, som er anbragt med hovedsagelig lodret akse, og med hvis stempel pattekoppesættet er forbundet, medens rummet i cylinderen over stemplet er tilslutteligt til en vacuumledning i malkemaskineanlægget ved omstilling af en ventil, som under styring af en i et elektrisk styrekredsløb indskudt, i forbindelse med stempel-cylinderenheden anbragt afbryder kan indstilles til lukning af forbindelsen mellem vacuumledningen og rummet over stemplet.The invention relates to an apparatus for raising and lowering a teat cup set in a milking machine, which comprises a vacuum working pneumatic piston-cylinder unit which is arranged with a substantially vertical axis and with which the piston teat cup set is connected, while the space in the cylinder above the piston is connectable to a vacuum line in the milking machine system by adjusting a valve which, under the control of a switch inserted in an electrical control circuit, can be adjusted in connection with the piston-cylinder unit for closing the connection between the vacuum line and the space above the piston.

I et sådant kendt apparat, som markedsføres af det engelske firma Gascoigne, - 2 - 147811 består ophængningsorganerne til ophsaigning af pattekoppesættet af et stempel med en membran, som ved sin rand er fastgjort tætsluttende ved stemplets overside.In such a known apparatus, marketed by the English company Gascoigne, the suspension means for lifting the teat cup set consist of a plunger with a diaphragm which is secured tightly at its upper edge at the top of the plunger.

Ved Membranens centrum er fastgjort en kort stang, som strækker sig ned gennem åbningen i stemplet, og som bærer en rulle, over hvilken er ført en snor, der ved sin ene ende er fastgjort ved den nedre ende af cylinderen, medens et pattekoppesæt er fastgjort i den anden ende.At the center of the diaphragm is fastened a short rod extending down through the aperture in the piston and carrying a roller over which is carried a string attached at one end to the lower end of the cylinder while a teat cup set is attached in the other end.

Stemplets øvre stilling i cylinderen er begraaiset af et anslag, og umiddelbart over dette er anbragt en mikroafbryder for en solenoide til styring af ventilen, som er en trevejsventil, gennem hvilken rummet over stemplet kan forbindes afvekslende til vakuum og til atmosfæren. Så Isenge pattekoppesættet hænger med sin vs^t i snoren, tre&kes membranen nedad i flad stilling mod virkningen af det på dens underside indvirkende atmosfæretryk og kan således ikke påvirke mi-kroafbryderen. Solenoiden holder derfor ventilen i en stilling til opretholdelse af vakuum over stemplet. Afløftes pattekoppesættet, ophæves trækket i snoren, hvorved membranen under påvirkning af vakuum og det atmosfæriske tryk hvaOLver sig opad og påvirker mikroafbryderen. Ventilen omstilles, hvorved vakuet over stemplet fjernes, og stemplet med stempelstang, ophængningsorganerne for pattekoppesættet og pattekoppesættet selv begynder at bevæge sig nedad, hvilket kan tilskyndes ved nedadrettet tråde i ophængningsorganerne. Den til apparatet hørende elektronik sørger herunder for, at ventilen forbliver i stilling til forbindelse af det øvre cylinderrum med atmosfæren, selv om påvirkningen af mikroafbryderen er ophørt. Herefter kan pattekoppesættet ved hjælp af patteholderen forbindes til koens yver. Samtidig har den elektriske styremekanisme sat pattekopperne under vakuum, således at koen malkes. Hvis der er indskudt en mælke-indikator i forbindelsen mellem pattekoppesættet og maskinens mælkeledning, og indikatoren signalerer en formindskelse af mælkestrømmen til mindre end 0,2 1 pr. minut, afbrydes vakuet automatisk igen. Også ventilen i stempel-cylinder-enheden genåbnes af den elektriske styremekanisme, hvorved der dannes et vakuum over stemplet, hvilket tilsikrer automatisk løftning af pattekoppesættet mod ophaaigt stilling.The upper position of the piston in the cylinder is buried by a stop and immediately above it is placed a microswitch for a solenoid for controlling the valve, which is a three-way valve through which the space above the piston can be alternately connected to vacuum and to the atmosphere. So the Isenge teat cup set hangs with its vs ^ t in the string, the diaphragm is pulled down in a flat position against the effect of the atmospheric pressure acting on its underside and thus cannot affect the microswitch. The solenoid therefore holds the valve in a position to maintain vacuum over the piston. If the teat cup set is lifted off, the pull in the string is lifted, whereby the membrane, under the influence of vacuum and atmospheric pressure, moves upwards and affects the microswitch. The valve is adjusted thereby removing the vacuum over the piston and the piston rod piston, teat cup set suspension means and teat cup set itself begin to move downward, which may be encouraged by downward threads in the suspension means. The electronics belonging to the appliance, among other things, ensure that the valve remains in position to connect the upper cylinder compartment with the atmosphere, even though the influence of the microswitch has ceased. The teat cup set can then be connected to the cow's udder by means of the teat cup holder. At the same time, the electric control mechanism has put the teat cups under vacuum so that the cow is milked. If a milk indicator is inserted into the connection between the teat cup set and the milk line of the machine and the indicator signals a decrease in milk flow to less than 0.2 liters per day. minute, the vacuum is automatically interrupted again. Also, the valve in the piston-cylinder unit is reopened by the electric control mechanism, thereby creating a vacuum over the piston, which ensures automatic lifting of the teat cup set to the raised position.

Membranen med afbryderen, fx. en mikroafbryder, er følsom over for mekaniske beskadigelser samt over for de korrosive indvirkninger, som optræder i en ko- stald i form af dampe fra ajle og staldgødning samt fra de i stalden anvendete rense- og desinfektionsmidler. Desuden er membranen og mikroafbryderen forholdsvis dyre elementer, og de skal være nøjagtigt justeret , således at opretholdel- - 3 - 1-4781 1 se af det kendte apparat i driftsklar tilstand bliver temmelig kostbart.The diaphragm with the switch, e.g. a microswitch is sensitive to mechanical damage as well as to the corrosive effects that occur in a dwelling in the form of vapors from eels and barn fertilizers and from the cleaning and disinfectants used in the stables. In addition, the diaphragm and the microswitch are relatively expensive elements and must be precisely adjusted so that maintaining the known apparatus in a ready-to-use condition becomes quite costly.

Den foreliggende opfindelse har til hensigt at afhjælpe disse ulemper og tilvejebringe et apparat af den ovenfor nævnte type, som ikke desto mindre er meget let at sætte igang, men ikke kan sættes igang af tilfældige bevægelser, fx. fra koen.The present invention aims to alleviate these disadvantages and to provide an apparatus of the type mentioned above which is nevertheless very easy to start but cannot be triggered by random movements, e.g. from the cow.

Dette er ifølge opfindelsen opnået ved, at afbryderen er en stillingsfølsom afbryder, fortrinsvis en kviksølvafbryder, som er indrettet til ved en vis ud-svingning af den svingeligt ophsaigte stempel-qylinderenhed fra den lodrette stilling at bevirke omstilling af ventilen til lukning af forbindelsen mellem vakuumledningen og cylinderrummet over stemplet.This is achieved according to the invention in that the switch is a position-sensitive switch, preferably a mercury switch, which is adapted to effect, by a certain swinging of the pivotally raised piston cylinder unit from the vertical position, to switch the valve to close the connection between the vacuum line. and the cylinder compartment above the piston.

Hertil er det kun nødvendigt at svinge stempel-cylinderenheden til en af de forudbestemte stillinger for at opnå, at afbryderen omstiller ventilen. Den galdrede stilling opretholdes af styremekanismen til trods for, at stempel-cylinderenheden vender tilbage til lodret stilling, efter at den er frigjort, indtil mælkeindikatoren signalerer en sådan formindskelse af mælkemængden, at malkningen skal ophøre.For this, it is only necessary to swing the piston-cylinder unit to one of the predetermined positions in order to achieve that the switch switches the valve. The staggered position is maintained by the control mechanism despite the piston-cylinder unit returning to the vertical position after it is released until the milk indicator signals such a decrease in milk volume that the milking must cease.

Afbryderen er fortrinsvis en kviksølvafbryder, som udgør et lukket gLaalege-me, og som tillige med sit indhold af kviksølv er modstandsdygtigt over for korrosive indvirkninger. Sidvidere aaidres polafstanden ikke ved mekaniske indvirkninger.The switch is preferably a mercury switch which constitutes a closed galley and which, together with its mercury content, is resistant to corrosive effects. In addition, the pole distance is not affected by mechanical effects.

Sædvanligvis er der et stort antal af malkeapparater i en malkestald, fx. på begge sider af en såkaldt malkegrav, hvor der er standpladser for et antal køer, hver forsynet med et malkeapparat eller -sæt.Usually there are a large number of milking machines in a milking parlor, e.g. on both sides of a so-called milking grave, where there are stands for a number of cows, each equipped with a milking apparatus or set.

Til nem igangsætning og for på samme tid at undgå, at afbryderen kan sættes i gang ved tilfældige bevægelser fra koen, er den stillingsfølsomme afbryder således anbragt i stempelcylinderenheden, at den kun bevirker omstilling af ventilen ved svingning af stempeloylinderenheden i retning bort fra standpladsen for t en ko, til hvilken pattekoppesættet skal tilsluttes.For easy start-up and at the same time to prevent the switch from being triggered by random movements from the cow, the position-sensitive switch is so arranged in the piston cylinder unit that it only causes the valve to be switched by pivoting the piston cylinder unit away from the position of t. a cow to which the teat cup set must be connected.

I en malkestald som ovenfor nævnt med en grav, er dette den måde, hvorpå malkeapparatet svinges i retning mod graven.In a milking parlor as mentioned above with a grave, this is the way in which the milking apparatus is pivoted in the direction towards the grave.

Et udførelseseksempel for et apparat ifølge opfindelsen beskrives nærmere i det følgende under henvisning til tegningen, hvor fig. 1 viser to standpladser i en malkestald, der er forsynet med et malkeapparat, hvor det venstre ikke er i drift, og det højre er i arbejdsstilling, og 147811 - 4 - fig. 2 viser det på fig. 1 viste, set fra højre.An exemplary embodiment of an apparatus according to the invention is described in more detail below with reference to the drawing, in which: FIG. 1 shows two pitches in a milking parlor provided with a milking apparatus where the left is not in operation and the right is in working position, and FIG. 2 shows that in FIG. 1, seen from the right.

?å fig. 1 er vist to æalkeapparater, der er identiske, således at kun det ene skal beskrives.? to fig. 1, two eagle appliances are shown which are identical so that only one is to be described.

Apparatet omfatter en stempel-cylinder-enhed 1, hvori der er anbragt et stempel 2 med en sterapelstang 3· Den nedre ende af stempelstangen har et pphseng-ningsøje 4, hvori et pattekoppesæt 6 er ophsaigt under indskydelse af en fleksibel snor 5· Pattekoppesættet har et centralt hus 7 med en vakuumventil, hvortil fire pattekoppeholdere 9 er forbundet ved hjæLp af slanger 8. Samtidig er en central melkeslange 10 forbundet med huset 7· Denne slange 10 fører til en stationær mælkeledning 11 hørende til malkemaskinen, hvilken ledning stra&ker sig langs alle malkestandene i stalden eller anden anbringelse af malkemaskinen. Endvidere er en vakuumslange 12 forbundet med huset 7 og fører til en vakuumledning 13, hørende til malkemaskinen. En mælkeindikator 14 findes anbragt i forbindelsesslangen 10. En vakuumforbindelse 15 er anbragt mellem cylinderen 1, hvor den er forbundet til et punkt over stenplet 2, og et andet rør 16 hørende til malkemaskinens vakuumledning. Hvor forbindelse 15 munder ind i cylinderen 1 findes en ventil 17, som kun er skematisk indikeret. Denne ventil tilfører eller fjerner vakuum til kammeret over stemplet 2.The apparatus comprises a piston-cylinder unit 1, in which a piston 2 is provided with a sterling rod 3. The lower end of the piston rod has a pep-bed eye 4, in which a teat cup set 6 is raised during insertion of a flexible string 5. a central housing 7 with a vacuum valve to which four teat cup holders 9 are connected by means of hoses 8. At the same time a central milk hose 10 is connected to the housing 7 · This hose 10 leads to a stationary milk conduit 11 belonging to the milking machine, which line extends along all the milking stands in the stable or other placement of the milking machine. Further, a vacuum hose 12 is connected to the housing 7 and leads to a vacuum line 13 associated with the milking machine. A milk indicator 14 is provided in the connection hose 10. A vacuum connection 15 is arranged between the cylinder 1, where it is connected to a point above the stone spot 2, and another tube 16 belonging to the vacuum line of the milking machine. Where connection 15 opens into the cylinder 1 there is a valve 17 which is only schematically indicated. This valve adds or removes vacuum to the chamber above the piston 2.

Det hidtil beskrevne apparat hører til teknikkens stade.The apparatus described so far belongs to the state of the art.

Ifølge den foreliggende opfindelse er der i nærheden af ventilen 17 på cylinderen 1 anbragt en stillingsfølsom afbryder 18, der er forbundet med en elektrisk styremékanisme ved hjæLp af hvilken afbryderen 18 kan åbne eller lukke ventilen 17. I den viste lodrette stilling for cylinderen 1 holder afbryderen 18 ventilen 17 åben, hvorved der findes vakuum over stemplet 2, og pattekoppesættet holdes ophsaigt eller i en stilling som vist ude af brug. Hvis stempel-qylinder-enheden 1, 2 svinges ud fra planet i fig. 1, dvs. i retning mod graven i malkestalden, omkring ophængnin^puriktet 19, som kan være et øje på cylinderens overside, og en bøjle monteret på vakuumledningen 16, bringes afbryderen 18 til at indtage en sådan stilling, at den lukker ventilen 17· Herved sankes pattekoppesættet 6 ved hjælp af dets ophaigningsorganer 4, 5 under tyngdens påvirkning, om nødvendigt hjulpet ved et nedadrettet trsåc heri, hvorved pattekoppesættet kan forbindes til koens yver. Herefter sikrer vakuum i forbindelsen 12, at koen malkes.According to the present invention, a position-sensitive switch 18 is provided in the vicinity of the valve 17 on the cylinder 1 by means of an electric control mechanism by means of which the switch 18 can open or close the valve 17. In the vertical position of the cylinder 1, the switch holds 18 the valve 17 is open, whereby there is a vacuum over the piston 2 and the teat cup set is held upright or in a position as shown out of use. If the piston-cylinder unit 1,2 is pivoted from the plane of FIG. 1, i.e. in the direction of the tomb in the milking parlor, around the suspension 19, which may be an eye on the top of the cylinder, and a bracket mounted on the vacuum line 16, causes the switch 18 to take such a position that it closes the valve 17 · thereby lowering the teat cup set 6 by means of its lifting means 4, 5, under the influence of gravity, if necessary aided by a downward saddle, herein, whereby the teat cup set can be connected to the udder of the cow. Thereafter, vacuum in the compound 12 ensures that the cow is milked.

Når den producerede mangle fra koen bliver mindre end 0,2 1 pr.minut, frembringer nælkeindikatoren 14 et signal, hvorved vakuet afspærres fra huset 7, Og 147811 - 5 - samtidig åbnes ventilen 17· Vakuet i pattekoppeholderen 9 hørende til pattekop-pesættet fjernes og forbindes med kammeret over stemplet 2, hvorved pattekoppe-sættet falder ned fra koens yver og automatisk vender tilbage til pattekoppesæt-tets ophængte stilling ved hjælp af vakuet, der findes over stemplet.When the shortage produced by the cow becomes less than 0.2 l per minute, the neck indicator 14 produces a signal, thereby blocking the vacuum from the housing 7, and simultaneously opening the valve 17 · The vacuum in the teat cup holder 9 belonging to the teat cup set is removed. and is connected to the chamber over the piston 2, whereby the teat cup set descends from the udder of the cow and automatically returns to the suspended position of the teat cup set by means of the vacuum located above the piston.

Den skråt udsvingede stilling af stempel-cylinderenheden er vist stiplet på fig. 2. Pattekoppesættet er på fig. 2 vist ophængt, men o^å i driftstilling efter svingningen, svarende til den venstre del af fig. 1, idet stempel-cylinderenheden er i den stilling, som er -vist fuldt optrukket på fig. 2.The obliquely oscillating position of the piston-cylinder unit is shown dotted in FIG. 2. The teat cup set is in FIG. 2 shown in suspension, but also in the operating position after the oscillation, corresponding to the left part of FIG. 1, the piston-cylinder unit being in the position shown fully drawn in FIG. 2nd

Det fremgår af tegningen, at standpladserne for køerne er afgrænset ved hjælp af vandrette og lodrette stsaiger 20 og 21. Malkeapparaterne er fortrinsvis anbragt umiddelbart ved siden af graven foran en vandret stang 20, således som det vises på fig. 1, således at apparatet ikke kan sættes i gang som følge af tilfældige bevægelser fra koen, da gravens og stangen 20*s tilstedeværelse forhindrer dette. Naturligvis kan andre foranstaltninger også traffes.It can be seen from the drawing that the locations of the cows are bounded by horizontal and vertical ladders 20 and 21. The milking apparatus is preferably placed immediately next to the grave in front of a horizontal bar 20, as shown in FIG. 1, so that the apparatus cannot be operated due to random movements of the cow, as the presence of the tomb and rod 20 * prevents this. Of course, other measures can also be taken.

Den stillingsfølsomme afbryder 18 kan være af en vilkårlig type, men en kviksølvafbryder er særlig velegnet.The position-sensitive switch 18 may be of any type, but a mercury switch is particularly suitable.
