Description

本発明は、ミルクの電気パラメーターを測定するための装置に関する。この装置は、搾乳装置の実質的に垂直な導管への配置を意図されており、かつ電極を持つ測定室を含む。本発明はまた、かかる装置を含む搾乳装置に関する。   The present invention relates to an apparatus for measuring the electrical parameters of milk. This device is intended for placement in a substantially vertical conduit of a milking device and includes a measurement chamber with electrodes. The invention also relates to a milking device comprising such a device.

電気伝導度のような電気パラメーターの測定は、搾乳分野で重要である。なぜなら、それは搾乳動物の乳房炎のような感染を検出するための手段として使用されることができるからである。ミルクが乳房炎または乳熱のために影響を受けると、ミルクの電気伝導度は変動させられる。従って、搾乳動物の乳房炎感染はミルクの電気伝導度の変動したパターンに基づいて診断されることができ、乳房炎感染の場合には特徴的な方法で増加される。電気伝導度は、例えば交流または直流電圧が印加されている電極により測定されることができる。異なる測定時間で比較しうる伝導度の値を得るために、伝導度の測定は既知の容積で実施されるべきである。従って、測定電極は、測定容積が各測定時で実質的に同じであるように配置されるべきであり、かくして電気伝導度の比較可能な値が得られることができる。   Measurement of electrical parameters such as electrical conductivity is important in the milking field. This is because it can be used as a means for detecting infections such as mastitis in milking animals. When milk is affected due to mastitis or milk fever, the electrical conductivity of the milk is varied. Thus, mastitis infections in milking animals can be diagnosed based on a varying pattern of milk electrical conductivity, which is increased in a characteristic way in the case of mastitis infection. The electrical conductivity can be measured, for example, by an electrode to which an AC or DC voltage is applied. In order to obtain conductivity values that can be compared at different measurement times, the conductivity measurement should be performed in a known volume. Thus, the measurement electrodes should be arranged so that the measurement volume is substantially the same at each measurement, and thus a comparable value of electrical conductivity can be obtained.

ミルクの伝導度の測定のための種々の装置がこの業界で知られている。伝導度を測定するための電極は典型的には、ミルク試料が受け入れられることができる試料室内に取付けられる。連続インライン測定のために、試料室は通常、乳頭カップとミルクラインの間の所定位置の搾乳装置に配置され、かつミルク流が通過するときミルクにより満たされる。   Various devices for measuring the conductivity of milk are known in the industry. Electrodes for measuring conductivity are typically mounted in a sample chamber where a milk sample can be received. For continuous in-line measurement, the sample chamber is usually placed in a milking device in place between the teat cup and the milk line and is filled with milk as the milk flow passes.

かかる装置の例はＷＯ９５／２２８８８及びＷＯ９９／１８７７４に示されており、そこでは試料室はミルク鉤爪内に設けられている。ミルクは上から試料室に入り、試料室の底に設けられた小さな開口を介してゆっくりと排出する。別の知られた装置はＥＰ０３９７２７４Ａ１に示されており、そこでは底が閉じられている試料室が設けられ、ミルクは上部開口を通して試料室に入りかつ出る。   Examples of such devices are shown in WO95 / 22888 and WO99 / 18774, where the sample chamber is provided in a milk claw. Milk enters the sample chamber from above and slowly drains through a small opening in the bottom of the sample chamber. Another known device is shown in EP 0 395 274 A1, in which a sample chamber with a closed bottom is provided, and milk enters and exits the sample chamber through the top opening.

ミルクの電気伝導度を測定するためのこれらの及び他のこれまで知られた装置はミルクの排出の困難性を持つ。ＷＯ９５／２２８８８またはＷＯ９９／１８７７４で示されたタイプの試料室では、排出開口は、ミルク試料を室内に保持するのに十分なほど小さくなければならない。しかし、かかる小さな開口はミルク中の脂肪の凝集または汚染粒子により容易に目詰まりする。ＥＰ０３９７２７４Ａ１に示されたタイプでは、ミルクが装置を通して流れるのをやめたときにも、少量のミルクが残る。試料室の妨げられたミルク排出は装置の浄化の障害物であり、また測定結果の信頼性に悪影響を及ぼすかもしれない。   These and other previously known devices for measuring the electrical conductivity of milk have difficulty in discharging milk. In sample chambers of the type shown in WO95 / 22888 or WO99 / 18774, the discharge opening must be small enough to hold the milk sample in the chamber. However, such small openings are easily clogged by fat agglomeration or contaminating particles in the milk. In the type shown in EP0397274A1, a small amount of milk remains even when the milk stops flowing through the device. Obstructed milk discharge in the sample chamber is an obstacle to the purification of the device and may adversely affect the reliability of the measurement results.

本発明は、上記の欠点を持たず、しかも信頼性ある測定を可能にし、かつ容易に浄化されることができる搾乳装置で使用するための電気パラメーターの測定のための改善された装置を提供することを目的とする。   The present invention provides an improved device for the measurement of electrical parameters for use in a milking device that does not have the above drawbacks, yet enables reliable measurement and can be easily purified. For the purpose.

これは、本発明によれば、請求項１に記載された装置により達成される。この装置は、搾乳装置の実質的に垂直なミルク流導管に配置され、かつ少なくとも二つの電極を持つ測定室を含む。ミルクはミルク流導管内を上向き方向に流れることを意図されており、測定室は上向き方向に閉じられ、かつミルクの流入及び流出のための下向きの開口を持つ。従って、この測定室は、ミルクが装置を通して上向きに流れるとき満たされ、ミルクが流れるのをやめるとき、重力のため、開口を通して即座に空になる。測定室がミルクで満たされると、信号が電極を介して測定室から得られることができる。この信号は、異なる搾乳時の伝導度の最大値を比較することにより、乳房炎のような病気を動物が患っているかどうかの評価のために使用されることができる。信号の存在はまた、装置を通したミルク流の存在を信頼性を持って示す。信号は、装置を通したミルクスラッグの通過時に連続的に与えられ、ミルクの少量の残留量は測定室から直接排出されるであろうから、ミルクスラッグが通過したとき停止するであろう。従って、ミルクスラッグが装置を通過するために必要な時間は容易に検出され、それはミルク導管の知られた容積と一緒にミルク流容積を計算可能にする。この装置は、ミルクが上向きに流れる実質的に垂直なミルク導管に配置されるのに適合されているので、それは、ミルクがとにかくミルクラインへ上向きに移動されなければならない高ライン搾乳用途で特に有用である。   This is achieved according to the invention by the device as claimed in claim 1. The device includes a measurement chamber disposed in a substantially vertical milk flow conduit of the milking device and having at least two electrodes. The milk is intended to flow upward in the milk flow conduit, the measuring chamber is closed in the upward direction and has a downward opening for the inflow and outflow of milk. This measuring chamber is therefore filled when milk flows upwards through the device and is immediately emptied through the opening due to gravity when milk stops flowing. When the measuring chamber is filled with milk, a signal can be obtained from the measuring chamber via the electrodes. This signal can be used to assess whether an animal is suffering from a disease such as mastitis by comparing the maximum conductivity values at different milkings. The presence of the signal also reliably indicates the presence of milk flow through the device. The signal will be applied continuously as the milk slug passes through the device, and a small residual amount of milk will be drained directly from the measuring chamber and will therefore stop when the milk slug passes. Thus, the time required for the milk slug to pass through the device is easily detected, which makes it possible to calculate the milk flow volume together with the known volume of the milk conduit. This device is adapted to be placed in a substantially vertical milk conduit where the milk flows upward, so it is particularly useful in high-line milking applications where the milk must be moved upward into the milk line anyway It is.

測定室は、ミルクが装置を通して流れるときミルク流方向が変えられるように装置内に配置されることが好ましい。ミルク流がその初期方向から偏向するとき、測定室に捕らえられたいかなる空気もミルク流と一緒に引張られ、従って、測定室は完全にミルクで満たされ、かつ空気は測定室内に捕らえられず、従って電気パラメーターの信頼性ある値が得られる。この装置はミルク流のための下方入口通路及び上方出口通路を含む。測定室は、その開口が下方ミルク流入口通路の直ぐ上に位置付けられるように位置され、従って装置に入るミルク流は、装置の外壁と外壁から延びる突出要素との間で境界付けられる測定室中に真直ぐ向けられる。   The measuring chamber is preferably arranged in the device so that the milk flow direction is changed when milk flows through the device. When the milk flow deflects from its initial direction, any air trapped in the measurement chamber is pulled along with the milk flow, so the measurement chamber is completely filled with milk and no air is trapped in the measurement chamber, A reliable value of the electrical parameter is thus obtained. The apparatus includes a lower inlet passage and an upper outlet passage for milk flow. The measuring chamber is positioned in such a way that its opening is positioned directly above the lower milk inlet passage, so that the milk flow entering the device is bounded between the outer wall of the device and a protruding element extending from the outer wall. Directly directed to.

この装置はダイヤフラム弁をさらに含み、測定室はそのとき流れ方向にダイヤフラムの前に配置される。この弁は流体室を含み、この流体室は流体入口開口と流体出口開口を持ち、この流体出口開口は、ダイヤフラムの方に向けられており、かつ流体室中に延びるミルク流出口通路の端部にある。測定室はダイヤフラムに対向してかつ出口通路の直ぐ下に位置されている。これは装置を小型にしかつ効率的にし、幾つかの目的が単一の装置により、特に流体室中に延びる出口通路の端部が測定室を限定する突出要素として使用されるとき達成されることができる。電極は、容易な取付け及び接近のために外壁内に配置され、かつ外壁を通して実質的に水平に延びることが好ましい。   The device further comprises a diaphragm valve, in which the measuring chamber is then placed in front of the diaphragm in the flow direction. The valve includes a fluid chamber, the fluid chamber having a fluid inlet opening and a fluid outlet opening, the fluid outlet opening being directed toward the diaphragm and the end of a milk outlet passage extending into the fluid chamber. It is in. The measurement chamber is located opposite the diaphragm and directly below the exit passage. This makes the device compact and efficient, and several objectives are achieved with a single device, especially when the end of the outlet passage extending into the fluid chamber is used as a protruding element that limits the measurement chamber. Can do. The electrodes are preferably disposed within the outer wall for easy attachment and access and extend substantially horizontally through the outer wall.

本発明はまた、動物の搾乳のための搾乳装置に関し、それは前記動物の乳頭に付与されることを意図された搾乳部材３０、搾乳部材３０から搾乳部材より高い位置に設けられているミルクライン３２へのミルクの輸送のためのミルク導管３１を含み、そこでは上述した装置は、測定室の開口が搾乳部材３０の方に向けられるようにミルク導管に配置される。   The invention also relates to a milking device for milking the animal, which is intended to be applied to the nipple of said animal, a milk line 32 provided from the milking member 30 to a position higher than the milking member. A milk conduit 31 for the transport of milk to the device, wherein the device described above is arranged in the milk conduit so that the opening of the measuring chamber is directed towards the milking member 30.

本発明の全体的な思想は、ミルク導管において上方端で閉じられかつ下方端で開いている測定室を設けることにあり、そこではこの測定室の内部空間は上向きに流れるミルクによって容易に進入されることができ、詰まりの危険は全くなく、しかもこの測定室は非常に浄化し易い。   The overall idea of the present invention is to provide a measuring chamber which is closed at the upper end and open at the lower end in the milk conduit, where the internal space of this measuring chamber is easily entered by the upward flowing milk. There is no risk of clogging, and this measuring chamber is very easy to clean.

本発明の測定室は、実際には搾乳部材の乳頭カップとミルクラインとの間のいかなる場所にも、ミルクが実質的に垂直方向に上向きに流れるミルク導管にそれが配置される限り、搾乳装置に配置されることができる。以下の説明を通して、本装置の空間的配向は、実質的に垂直なミルク導管に配置されたときと同じであると仮定している。従って、本装置の下方または底部要素は上方または上部要素より搾乳部材に接近して設けられるであろう。   The measuring chamber of the present invention is actually a milking device as long as it is placed in a milk conduit where milk flows substantially vertically upwards anywhere between the teat cup and milk line of the milking member. Can be arranged. Throughout the following description, it is assumed that the spatial orientation of the device is the same as when placed in a substantially vertical milk conduit. Thus, the lower or bottom element of the device will be provided closer to the milking member than the upper or upper element.

図１に示された本発明の第一実施態様では、装置１は管状部を含み、この管状部内に二つの電極２を含む測定室９が配置されている。測定室は管状部の壁４から延びる突出要素３により境界付けられる。ミルクは装置に下から入口通路５を通して入り、真直ぐに測定室９に向けられる。突出要素３はミルクの流れ方向に設けられ、従ってミルク流がその初期方向を持続するのを妨げ、代わりにミルク流を偏向させ、測定室９のそばの管状要素内に残された隙間を通って流れる。ミルクは次いで上方出口通路６を通って装置を離れる。   In the first embodiment of the invention shown in FIG. 1, the device 1 comprises a tubular part, in which a measuring chamber 9 comprising two electrodes 2 is arranged. The measuring chamber is bounded by a protruding element 3 extending from the wall 4 of the tubular part. Milk enters the apparatus from below through the inlet passage 5 and is directed straight into the measuring chamber 9. The projecting element 3 is provided in the milk flow direction, thus preventing the milk flow from maintaining its initial direction and instead deflecting the milk flow through the gap left in the tubular element by the measuring chamber 9. Flowing. The milk then leaves the device through the upper outlet passage 6.

測定室９は上向き方向に突出要素３により閉じられ、ミルクの流入及び流出のために下向き方向に開かれている。突出要素３は、測定室９の側壁を規定する複数の実質的に垂直な壁部材７、及び測定室の上方壁を規定する上方壁部材８を含むことが好ましい。特に有利な代替例では、上方壁部材８は、好ましくは放物線に沿って壁上のそれが延びる点（測定室の後端）から下向きに測定室の開口まで傾斜するように傾けられている。従って、測定室９は、上向きに先細りとなっており、それが壁４に最も接近した領域でより深く、かつ上方壁部材８の下方部に近い領域でむしろ浅いように、上方後端でより狭くなっている。これは、ミルク流の測定室中への流入及びそれからの流出の効率、並びに測定室内で捕らえられたいかなる空気の除去も強化するであろう。   The measuring chamber 9 is closed in the upward direction by the projecting element 3 and is opened in the downward direction for the inflow and outflow of milk. The protruding element 3 preferably comprises a plurality of substantially vertical wall members 7 defining the side walls of the measurement chamber 9 and an upper wall member 8 defining the upper wall of the measurement chamber. In a particularly advantageous alternative, the upper wall member 8 is inclined so as to be inclined downwardly from the point where it extends on the wall along the parabola (the rear end of the measurement chamber) to the opening of the measurement chamber. Therefore, the measuring chamber 9 tapers upwards and is deeper in the region closest to the wall 4 and rather shallow in the region close to the lower part of the upper wall member 8 and more at the upper rear end. It is narrower. This will enhance the efficiency of the milk flow into and out of the measurement chamber and the removal of any air trapped in the measurement chamber.

図２〜６は本発明の第二実施態様を示し、そこでは減圧調節ダイヤフラム弁（遮断弁）が装置１０に組込まれている。この弁は少しカップ形状の要素２７とダイヤフラム２６を含む流体室１１を含む。ダイヤフラムは図３にのみ示されている。流体室１１はその底部にミルク入口開口２０を含み、実質的に管状のミルク入口通路１５が流体室の下の入口開口に取付けられている。ミルク出口通路１６が流体室の上方端に配置されている。出口通路１６は、主として流体室１１の外側に設けられた上方の実質的管状部、及び流体室の内側に設けられた下方延長部１８，２１から構成される。流体室１１からのミルク出口開口２２は延長部１８，２１の端部に設けられ、かつ出口開口２２を包囲する縁端２３は、出口開口を通る通路のサイズがダイヤフラム２６の動きにより制御されることができるように、ダイヤフラム２６が封止することができる封止表面を形成する。また、出口開口２２をダイヤフラム２６により完全に閉じることもできる。ミルクは実質的に水平方向に出口開口２２を通して出て、次いで実質的に垂直方向に出口通路１６を通して上向きに方向を変える。   2 to 6 show a second embodiment of the present invention, in which a depressurization regulating diaphragm valve (shutoff valve) is incorporated in the device 10. This valve comprises a fluid chamber 11 containing a slightly cup-shaped element 27 and a diaphragm 26. The diaphragm is only shown in FIG. The fluid chamber 11 includes a milk inlet opening 20 at the bottom, and a substantially tubular milk inlet passage 15 is attached to the inlet opening below the fluid chamber. A milk outlet passage 16 is arranged at the upper end of the fluid chamber. The outlet passage 16 mainly includes an upper substantially tubular portion provided outside the fluid chamber 11 and lower extensions 18 and 21 provided inside the fluid chamber. A milk outlet opening 22 from the fluid chamber 11 is provided at the ends of the extensions 18, 21, and the edge 23 surrounding the outlet opening 22 is controlled by the movement of the diaphragm 26 in the size of the passage through the outlet opening. The sealing surface is formed so that the diaphragm 26 can be sealed. Also, the outlet opening 22 can be completely closed by the diaphragm 26. The milk exits through the outlet opening 22 in a substantially horizontal direction and then turns upward through the outlet passage 16 in a substantially vertical direction.

この実施態様では、測定室１９は流体室１１内に位置され、ダイヤフラムの視点から見たとき、出口通路１６の下方延長部１８の真下及び部分的に後ろに設けられる。測定室は、出口通路の下方延長部１８，２１の一部である突出要素１３及び実質的に垂直な側壁表面１７により境界付けられる溝として形成されることができる。測定室の内部形状は、第一実施態様のために上述されたのと同じであってもよく、すなわち上方後端で開口より狭くなっていてもよい。   In this embodiment, the measurement chamber 19 is located in the fluid chamber 11 and is provided directly below and partially behind the lower extension 18 of the outlet passage 16 when viewed from the diaphragm perspective. The measuring chamber can be formed as a groove bounded by a protruding element 13 which is part of the lower extension 18, 21 of the outlet passage and a substantially vertical side wall surface 17. The internal shape of the measurement chamber may be the same as described above for the first embodiment, i.e. it may be narrower than the opening at the upper rear end.

本装置は、好ましくはプラスチック材料から、一体的に流体室１１、入口通路１５、測定室１９及び出口通路１６を含むワンピースとして成形される。後壁１４の開口を通して実質的に水平に延びる二つの電極１２が測定室１９に配置されている。電極接続は、開口２５周りに配置された保護壁２４により保護される。   The device is preferably molded from a plastic material as a one-piece comprising a fluid chamber 11, an inlet passage 15, a measuring chamber 19 and an outlet passage 16. Two electrodes 12 extending substantially horizontally through the opening in the rear wall 14 are arranged in the measurement chamber 19. The electrode connection is protected by a protective wall 24 arranged around the opening 25.

使用時に、ミルクは第一実施態様に対して述べたのと同様に装置を通して上向きに流れる。測定室１９の領域で方向を変えた後、ミルク流は流体室の出口開口２２を介して、出口通路を通して流体室１１を離れる。   In use, the milk flows upward through the device as described for the first embodiment. After changing direction in the region of the measuring chamber 19, the milk flow leaves the fluid chamber 11 through the outlet passage through the outlet opening 22 of the fluid chamber.
