Ventilen dr dessutom anordnad att omvaxlande sluta och Oppna forbindelse mellan portioneringsrummet, ena sidan, och dais en expansionsledning, dels även ett inluftningsror, a andra sidan. Inventor: F R Henriksson The present invention relates to a dispensing apparatus for water shoes, which is provided with an operating means for a valve for, alternately closing and opening an inlet to a portioning room and a drain from the portioning room. The valve is also arranged to alternately close and open a connection between the portioning space, on one side, and there is an expansion line, and also an aeration pipe, on the other side.

Enligt uppfinningen är ventilen anordnad att under manovreringen av manoverorganet, vilket foretradesvis är utfort som ett hand-tag, genomlopa fyra laser, namligen en fOrsta fas, i vilken portioneringsrummet ar fOrbundet med utloppsledningen och med inluftningsledningen, en andra fas, i vilken portioneringsrummet ãr forbundet med inluftningsledningen och expansionsledningen, en tredje fas, i vilken portioneringsrummet är fOrbundet med tilloppsledningen och expansionsledningen, och en fjarde fas, i vilken portioneringsrummet icke är forbundet med nagon av de fyra ledningarna, eventuellt undantaget a vloppsledningen. According to the invention, the valve is arranged to pass through four lasers during the operation of the operating member, which is preferably designed as a handle, namely a first phase, in which the portioning space is connected to the outlet line and to the vent line, a second phase, in which the portioning space is connected with the aeration line and the expansion line, a third phase, in which the portioning space is connected to the supply line and the expansion line, and a fourth phase, in which the portioning space is not connected to any of the four lines, optionally except for the overflow line.

Uppfinningen kommer nedan att beskrivas samband med ett utforingsexempel, som sarskill hanfor sig till en myntautomatkontrollerad utrninuteringsapparat, avsedd i forsta hand for utminutering portionsvis ,av kaffe, som bryggts i en till utminuteringsapparaten ansluten kaffebryggare eller s. k. kaffemaskin. Beskrivningen ansluter sig till bifogade ritning, pa vilken fig. 1 visar en langdgenomskarning av apparaten i dess helhet, jamval innefattande myntautomaten, under det att fig. 2, 3, 4 och 5 visa skisser, utvisande de olika lagen som en i apparaten inghende ventil successivt intager under apparatens manavrming. The invention will be described below in connection with an exemplary embodiment, which differs from a coin-operated machine-controlled dispensing device, intended primarily for dispensing batchwise, of coffee brewed in a coffee maker or so-called coffee machine connected to the dispensing device. The description relates to the accompanying drawing, in which Fig. 1 shows a longitudinal section of the apparatus in its entirety, including the coin machine, while Figs. 2, 3, 4 and 5 show sketches, showing the different layers as a valve included in the apparatus. successively consumes during operation of the appliance.

Pa fig. 1 Sr myntautomaten i sin helhet betecknad med 10 och den egentliga portioneringsapparaten med 11. Myntautomaten kan vara av en var for andamalet lampad konstruktion, och den skall darfor endast be skrivas i korta drag hdr. Den Sr inrymd inom ett holje 12 och forsedd med en myntoppning 13. Omedelbart under myntoppningen 13 Sr en vals 14 anordnad, sa att myntet, da det faller ned genom myntoppningen, upptages i en ficka i valsen 14, dar det astadkommer koppling mellan valsens axel 15 och en utgaende axel 16 till portioneringsapparaten. Axeln 15 stracker sig ut genom holjet 12 till en manoverratt 17, under det att axeln 16 medelst en medbringare 18 och en koppling 19 Sr f5renad med axeln 20 till portioneringsapparaten. In Fig. 1, the coin vending machine in its entirety is denoted by 10 and the actual portioning apparatus by 11. The coin vending machine can be of a construction which is individually lit, and it should therefore only be described in brief hdr. It is housed within a housing 12 and provided with a coin opening 13. Immediately below the coin opening 13 is a roller 14 arranged so that the coin, as it falls down through the coin opening, is received in a pocket in the roller 14, where it provides coupling between the shaft of the roller. 15 and an output shaft 16 to the portioning apparatus. The shaft 15 extends through the housing 12 to a control knob 17, while the shaft 16 is connected by means of a carrier 18 and a coupling 19 Sr to the shaft 20 of the portioning apparatus.

Portioneringsapparaten innehaller i fOrsta hand ett portioneringsrurn av avmatt rymd, utat begransat av en rorformad vagg 21 och tva gavlar 22 och 23. Gaveln 22 Sr ansluten till inre kanten pa den rorformade vaggen 21 under inkoppling av en tatning 24 saint forsedd med ett centralt hal med tatning 26 for axeln 20. Gaveln 23 Sr anordnad att forbindas med portioneringsapparatens stativ 27, vilket exempelvis kan utgoras av vaggen till en behallare for den dryck, som skall portioneras, .exempelvis en kaffeberedare. Anslutningen sker med hjalp av en del 28, som Sr framstalld i .ett stycke med vaggen 23, och som inneballer -vissa for anordningens funktion vitala delar: Sdlunda Riper centralt genom delen 28 en kanal 29 for tillforsel av den utminuterade vatskan. I omedelbar narhet av portioneringskarlets hogsta punkt befinner .sig i vaggen en. Oppning, som kommunicerar med en kanal 30, vilken avslutas med en anslutningsbussning 31 kir ett vertikalt eller tillnarmelsevis vertikalt uppat lopande expansionsror. Detta rar, som icke Sr visat pa ritningen kan eventuellt avslutas med en expansionsbehallare, eventuellt kan det i stallet lopa tillbaka in i kaffeberedaren. Pa ett stalle i narheten. av portioneringsrummets periferi Sr vidare ett inluftningshal 32 anordnat i filirening med en pa ritningen icke visad backstromningsventil. De Ire salunda i gaveln 23 forefintliga oppningarna ligga fran mitten av.gaveln upp-. 2— — at, under det att i den undre halften av gavein 23 ett avtappningshal ar forbundet med en avtappningsledning 33 f8r den portionerade vatskan. De fyra oppningarna tackas av en vridbar ventilskiva 34, vilken medelst en bussning 35 ar fast pa axeln 20, sa att den kommer att rotera vid vridning av handtaget 17. I ski-van är en oppning upptagen, vilken bestar av en radial' del 36 av sadan bredd, att den i huvudsak heft ansluter sig till diameter. paoppningarna till ledningarna 29 resp. 33, och av en periferiell del 37 av sadan bredd, att den ansluter sig till diametern pa oppningarna 30 och 32. The portioning apparatus primarily comprises a portioning tube of measured space, externally bounded by a tubular cradle 21 and two ends 22 and 23. The end cap 22 is connected to the inner edge of the tubular cradle 21 while connecting a seal 24 saint provided with a central hall with seal 26 for the shaft 20. The end 23 is arranged to be connected to the rack 27 of the portioning apparatus, which can for instance be formed by the cradle into a container for the beverage to be portioned, for example a coffee maker. The connection is made with the aid of a part 28, which is shown in one piece with the cradle 23, and which comprises - some vital parts for the function of the device: Sdlunda Scratches centrally through the part 28 a channel 29 for supply of the exhausted liquid. In the immediate vicinity of the highest point of the portioning vessel, one is located in the cradle. An opening which communicates with a channel 30, which terminates with a connecting bushing 31 in a vertically or approximately vertically upwardly extending expansion tube. This jar, which is not shown in the drawing, can possibly be finished with an expansion container, it may instead run back into the coffee maker. In a place nearby. of the periphery of the portioning space Sr further an aeration hall 32 arranged in filing with a backflow valve (not shown in the drawing). The openings present in the gable 23 lie from the middle of the gable up-. 2, - that in the lower half of the gift 23 a drain hall is connected to a drain line 33 for the portioned liquid. The four openings are thanked by a rotatable valve disc 34, which by means of a bushing 35 is fixed to the shaft 20, so that it will rotate when the handle 17 is rotated. of such a width that it substantially adheres to the diameter. the openings to the lines 29 resp. 33, and of a peripheral portion 37 of such a width that it conforms to the diameter of the openings 30 and 32.

Anordningen fungerar pa foljande satt: Under senaste avtappning av dryck fran portioneringsanordningen har ventilskivan 34 overfOrts till det lage, som framgar av fig. 2. Den radiella slitsdelen 36 kommunicerar dar med avtappningsledningen 33, och for att icke vakuum skall uppkomma i portioneringskarlet, ãr den periferiella slitsdelen 37 satt i forbindelse med inluftningsoppningen 32. Dennas backventil ar sa riktad, att luft inslappes i portioneringskarlet men icke vatska kan utga darifran. Portioneringskarlet har darfor tomts pa den portionerade vatskan, och i stallet har luft tillforts. The device operates as follows: During the last discharge of beverage from the dispensing device, the valve disc 34 has been transferred to the layer shown in Fig. 2. The radial slot 36 communicates there with the dispensing line 33, and in order not to create vacuum in the dispensing vessel, it is peripheral slit portion 37 is connected to the vent opening 32. Its check valve is so directed that air is let into the portioning vessel but no liquid can escape therefrom. The portioning vessel has therefore been emptied of the portioned liquid, and air has been supplied instead.

Insattandet av ett mynt i myntoppningen 13 medger nu, att ventilskivans axel vrides runt med hjalp av handtaget 17. Darvid sker ventilskivans vridning I riktningen av pilen 38, fig. 2, 3, 4 och 5, varvid fOrst avtappningsoppningen 33 tamligen snabbt slutes till och darefter, mot slutet av den forsta rorelsen om ett kvarts vary kommunikation oppnas mei- Ian expansionsroret 30 och inluftningsroret 32. Sasom nedan skall beskrivas, kan det intraffa, att en del av den i narmast foregaemple utminutering av dryck tillforda vatskan kan hava stigit upp i expansionsrOret. Om sa skulle vara fallet, kan nu denna kvantitet av vatskan stromma tillbaka ned i portionerings_ karlet genom ledningen 30 under samtidig undantrangning av motsvarande kvantitet luft genom samma ror. The insertion of a coin into the coin opening 13 now allows the shaft of the valve disc to be rotated by means of the handle 17. In this case the valve disc rotates in the direction of the arrow 38, Figs. 2, 3, 4 and 5, whereby first the draining opening 33 closes rather quickly and then, towards the end of the first movement about a quarter of a minute, communication is opened between the expansion tube 30 and the aeration tube 32. As will be described below, it may happen that part of the immediately preceding minimization of beverage supplying the liquid may have risen in expansion rOret. If so, this quantity of liquid can now flow back down into the portioning vessel through the conduit 30 while simultaneously displacing the corresponding quantity of air through the same tube.

Efter fullbordandet av ytterligare ett kvarts varvs vridning kommer -ventilskivan 34 att std I det lage, som visas i fig. 4. Rummet kommunicerar nu dels med expansionsroret 30 for a-vgivande av luft under pagaende fyllning av rummet, dels aven med tillfOrselledningen 29, varigenom rummet snabbt fylles med den vatska, som skull utminuteras. Det ar under sista fasen av palyllningsperioden, som eventuellt en mindre kvantitet av vatskan kan trangas upp i expansionsroret. Dessutom kan det intraffa, att den utminuterade vatskan är varm, sa som .exempelvis ar fallet, dd det är fragan am att utminutera kaffebrygd, och att del heta kaffet kan i finfordelad droppform folja med den undantrangda luften upp i expansionsroret. After completion of a further quarter of a turn of rotation, the valve disc 34 will stand in the position shown in Fig. 4. The chamber now communicates partly with the expansion tube 30 for a-release of air during paging filling of the chamber, partly also with the supply line 29, whereby the room is quickly filled with the liquid, which is to be mined. It is during the last phase of the filling period that a smaller quantity of the liquid may be forced up into the expansion tube. In addition, it may happen that the exhausted liquid is hot, as is the case, for example, when it is a question of minimizing coffee brewing, and that some hot coffee may in finely divided droplet form follow with the displaced air up into the expansion tube.

Sedan portioneringsrummet pa detta satt blivit fylld med vatska, fortsattes vridningen av ventilskivan till det lage, som visas I fig. 5, varvid kommunikation 8ppnas mellan portioneringsrummet och avloppsledningen 33, och den utminuterade vitskan borjar till en Mrjan att sakta rinna ut genom denna ledning. Darvid bildas ett strOmningen i viss man. hejdande vakuurn i portioneringsrummet, men sedan ventilskivan vridits det sista kvartsvarvet, sa att den atergatt till det tillstand, som visas i fig. 2, oppnas jamval kommunikation med inluftningsledningen 32, och vatskan strommar ut ur portioneringsrummet med full intensitet. After the portioning space has thus been filled with liquid, the rotation of the valve disc to the layer shown in Fig. 5 is continued, communication being opened between the portioning space and the drain line 33, and the exhausted whitening begins to slowly flow out through this line. Thereby a flow is formed in a certain man. stopping the vacuum in the portioning space, but after the valve disc has been rotated the last quarter turn, so that it returns to the state shown in Fig. 2, parallel communication with the vent line 32 is opened, and the liquid flows out of the portioning space at full intensity.

Det är synbarligen av betydelse, att errorlerlig tid star till buds dels for vatskans instromning, vilken ager rum i huvudsak under tiden, medan ventilskivan befinner sig i det lage, sompa fig. 4, dvs. efter ett halvt varvs vridning fran vilolaget. F5r att sakerstalla, att ventilskivan icke vrides fOrbi detta lage alltfOr snabbt kan man anordna apparaten sa, att den tvangsmassigt bringas att stanna viss lid i det angivna laget. Ett sarskilt ,enkelt salt att astadkomma denna verkan är att inratta myritautomaten sa, att ilaggandet av tvd mynt ar erforderligt fOr vridning av ventilskivan ett helt vary, namligen ett forsta mynt for vridning av ventilskivan det f6rsta halva varvet och ett andra mynt for vridning av ventilskivan det andra halva varvet. Vid en sadan anordning bOr myntoppningen pa sedvanligt sat vara begransad sa, att den endast kan mottaga ett mynt, men det kan vara bekvamt att anordna den sa, att det andra av de tva mynten kan instickas i myntoppningen och kvarhallas dar utan att falla ned, tills det forsta mynlet lamnat myntspringan och faller ned i den under myntautomaten befintliga behallaren, samt darefter valsen vrides tillbaka till utgangspunkten for att fran myntoppninen mottaga det andra myntet. liven andra anordningar kunna forekomma for samma andamal. It is obviously important that error-free time is available partly for the inflow of the liquid, which takes place mainly during the time, while the valve disc is in the low position, as shown in Fig. 4, i.e. after half a turn turning from the resting layer. In order to ensure that the valve disc does not rotate past this position too quickly, the apparatus can be arranged so that it is forced to stop certain suffering in the specified position. A special, simple salt to achieve this effect is to set up the myrita machine so that the insertion of two coins is required for turning the valve disc a whole vary, namely a first coin for turning the valve disc the first half turn and a second coin for turning the valve disc. the other half lap. In such a device the coin topping should normally be limited so that it can only receive one coin, but it may be convenient to arrange it so that the other of the two coins can be inserted into the coin topping and retained there without falling down. until the first coin has left the coin slot and falls into the container under the coin machine, and then the roller is turned back to the starting point to receive the second coin from the coin top. other devices may occur for the same purpose.

Portioneringsanordningen kan givetvis anvandas i annul sammanhang an med en. myntautomat. Aven i delta fall är det emellertid av betydelse, att ett uppehall i kringvridningen av ventilskivan sker, da portioneringsrummet skall fyllas, sa att erforderlig lid erhalles for fyllandet. I detta fall kan man exempelvis anordna handtaget sa, att det endast kan vridas ett halvt vary i taget. Kopplingen 19 bor da. vara s. -afford, an den under vridningen av handtaget medtager axeln 20 i sin r5- relse, men. under atergangen av handtaget skall genom en snapphakekonstruktion eller liknande axeln 20 kvarhallas i det intagna laget. Dâ darefter handtaget for andra gangen vrides ett halvt vary, medtages aterigen genom snapphakens funktion axeln 20, sa att ventilskivan kommer att vridas aterstoden for fullbordande av ett helt varvs rotation, dvs. ventilskivan overfores under det forsta halva — —3 varvet fran laget enligt fig. 2 till laget enligt fig. 4 under passerande av laget enligt fig. 3, och under det andra halva varvet fran laget enligt fig. 4 tillbaka till laget enligt fig. 2 under passerande av laget enligt fig. 5. The portioning device can of course be used in the annul context of a. coin machine. Even in these cases, however, it is important that a pause in the rotation of the valve disc takes place, as the portioning space must be filled, so that the required lid is obtained for filling. In this case, for example, the handle can be arranged so that it can only be turned half a turn at a time. The coupling 19 lives then. be s. -afford, an it during the rotation of the handle includes the shaft 20 in its movement, but. during the return of the handle, the snap hook construction or similar shaft 20 must be retained in the intake layer. When the handle is turned for the second time for half a turn, the shaft 20 is again taken by the function of the snap hook, so that the valve disc will be turned the remainder to complete the rotation of a full turn, i.e. the valve disc is transferred during the first half - 3 turns from the layer according to Fig. 2 to the layer according to Fig. 4 while passing the layer according to Fig. 3, and during the second half turn from the layer according to Fig. 4 back to the layer according to Fig. 2 while passing the team according to Fig. 5.

Apparaten kan for kontroll av antalet utminuterade enhetsvolymer forses med ett rakneverk. F5r andamalet ar ph axeln fran kopplingen 19 ett kugghjul 39 pasatt, vilket befinner sig i ingrepp med ett kugghjul 40, vilket med pa ritningen icke visade medel OyerfOr sin rorelse till rakneverket. The device can be equipped with a rake to control the number of exhausted unit volumes. For this purpose, the shaft from the clutch 19 is a gear 39 fitted, which is in engagement with a gear 40, which with means not shown in the drawing shows its movement to the rake.

Uppfinningen Or givetvis icke inskrankt till den sarskilda utforingsform, som ovan beskrivits sasom utfOringsexempel ph uppfinningen, och vilken visats a ritningen, utan olika modifikationer kunna .forekomma mom uppfinningens ram. The invention is of course not limited to the particular embodiment described above as an embodiment of the invention, and which is shown in the drawing, without various modifications which may occur within the scope of the invention.
