Abstract

The device for dispensing metered quantities of free-flowing material has an upper part (1) to which a vessel (18) for the material can be coupled, and which contains a through passage (8). A lower part (2) is fixed in line with the upper one and also has an opening (12) through it, offset by an angle from the passage in the upper one, so that the two do not overlap. Between the upper and lower parts is an intermediate one (3) which can be turned, and which contains an aperture whose vol (9) determines the quantity dispensed. The aperture is brought alternately into line with the first passage (8), to receive material from the vessel, and with second opening (12), so as to discharge it through the lower part.

Description

452 589 höjd. Den har liksom den övre delen 1 en genomgående, excen- trisk öppning 9 av i huvudsak samma diameter som delens 1 öpp- ning 8. öppningens 9 centrum befinner sig på samma avstånd från mellandelens 3 centrum som den övre delens 1 öppning 8 befinner sig från delens 1 centrum. Delarna 1 och 3 har sålun- da ett inbördes vridläge, i vilket öppningarna 8 och 9 är ko- axiella. 452 589 height. Like the upper part 1, it has a continuous, ex- technical opening 9 of substantially the same diameter as the opening of the part 1 ning 8. the center of the opening 9 is at the same distance from the center of the middle part 3 as the opening 8 of the upper part 1 is located from the center of part 1. Parts 1 and 3 have thus a mutual rotational position, in which the openings 8 and 9 are coded axiella.

I mellandelen 3 finnes vidare ett bågformigt, med mel- landelen koncentriskt urtag 10, vilket mynnar i mellandelens 3 i användningsläget övre yta. Urtaget 10 hyser en tryckspi- ralfjäder 11.In the intermediate part 3 there is furthermore an arcuate, with intermediate land part concentric recess 10, which opens into the middle part 3 in the upper surface use position. The recess 10 houses a pressure coil spring 11.

Den nedre delen 2 utgöres liksom mellandelen 3 av en i huvudsak massiv, cylindrisk kropp av samma diameter som delarna 1 och 3, men vars höjd icke behöver vara större än vad som erfordras för att den nedre delen 2 med det för den- samma begagnade materialet skall vara i huvudsak styv. Även den nedre delen 2 har en genomgående.öppning 12 av samma dia- meter som öppningarna 8 och 9 och på samma radiella avstånd från delens 2 centrum som öppningarna 8 och 9 befinner sig från delens 1 resp. delens 3 centrum.The lower part 2, like the intermediate part 3, consists of one essentially solid, cylindrical body of the same diameter as parts 1 and 3, but the height of which need not exceed what is required for the lower part 2 with that for the the same used material should be substantially rigid. Also the lower part 2 has a through-opening 12 of the same diameter meters as the openings 8 and 9 and at the same radial distance from the center of the part 2 where the openings 8 and 9 are located from part 1 resp. part 3 center.

I delens 1 botten 5 är fäst en central axeltapp, vars närmast bottnen 5 befintliga del är cirkulär och har en längd, som motsvarar mellandelens 3 höjd. Mellandelen 3 har en mot- svarande genomgående, central öppning 14, i vilken axeltappens 13 cirkulära del passar med glidpassning. Axeltappen 13 avslu- tas med en icke-cirkulär änddel 15, som vid den visade utfö- ringsformen har kvadratiskt tvärsnitt och vars största tvär- dimension är mindre än axeltappens 13 cirkulära dels diameter.Attached to the bottom 5 of the part 1 is a central shaft pin, whose the part closest to the bottom 5 is circular and has a length, which corresponds to the height of the intermediate part 3. The intermediate part 3 has a counter- corresponding through-going, central opening 14, in which the shaft pin 13 circular part fits with sliding fit. Shaft pin 13 closing with a non-circular end portion 15, which in the embodiment shown has a square cross-section and whose largest cross-section dimension is smaller than the diameter of the circular part of the shaft journal 13.

Den icke-cirkulära änddelen 15 har samma längd, som den nedre delens 2 höjd. Änddelen passar, företrädesvis tämligen styvt, i en motsvarande genomgående, central, icke-cirkulär öppning 16 i den nedre delen 2.The non-circular end portion 15 has the same length as the lower one part 2 height. The end portion fits, preferably rather rigidly, in a corresponding continuous, central, non-circular opening 16 in the lower part 2.

Av det ovanstående framgår, att delarna 1-3 kan samman- fogas genom att mellandelen 3 med den centrala öppningen 14 påträdes axeltappens 13 cirkulära del och den nedre delen 2 med sin centrala öppning 16 påträdes axeltappens 13 icke- cirkulära änddel 15,samt att sedan så skutt mellandelen 3 är vridbar i förhållande till den övre delen 1 och den nedre -11 3 452 589 delen 2. De tre delarna hindras från att falla isär av en stoppskruv 17, som är inskruvningsbar i ett axiellt botten- hål i axeln 13 och som har ett huvud av större diameter än delens 2 centrala öppnings 16 största tvärdimension.From the above it appears that parts 1-3 can be combined joined by the intermediate part 3 with the central opening 14 the circular part of the shaft journal 13 and the lower part 2 are applied with its central opening 16, the non- circular end part 15, and that then so shot the middle part 3 is rotatable relative to the upper part 1 and the lower part -11 3 452 589 part 2. The three parts are prevented from falling apart by one stop screw 17, which can be screwed into an axial bottom holes in the shaft 13 and having a head of larger diameter than part 16 central opening 16 largest transverse dimension.

Vid hopmonteringen av de tre delarna på det ovan be- skrivna sättet anordnas den nedre delen 2 i ett sådant vrid- läge i förhållande till den övre delen 1, att den förras öpp- ning 12 kommer att befinna sig i ett läge, i vilket den är vinkelförskjuten från den övre delens 1 öppning 8 åtminstone så mycket, att ingen del av öppningen 12 överlappar någon del av öppningen 8, sett i med delarnas gemensamma centrumax- el parallella riktningar. Exempelvis kan den radie, som inne- håller öppningens 12 centrum, bilda i huvudsak rät vinkel mot den radie, som innehåller öppningens 8 centrum.When assembling the three parts on the above in the written manner, the lower part 2 is arranged in such a rotating position in relation to the upper part 1, that it is opened 12 will be in a position in which it is angularly displaced from the opening 8 of the upper part 1 at least so much so that no part of the opening 12 overlaps any part of the opening 8, seen in with the common center axis of the parts or parallel directions. For example, the radius contained in holding the center 12 of the opening, forming a substantially right angle to the radius, which contains the center 8 of the opening.

Såsom nämnts ovan och såsom framgår av den beskrivna konstruktionen är mellandelen 3 vridbar mellan delarna 1 och 2 och i förhållande till dessa. Mellandelen 3 kan sålunda. vridas från ett läge, i vilket dess öppning 9 befinner sig mitt för delens 1 öppning 8, till ett läge, i vilket öppningen 9 befinner sig mitt för delens 2 öppning 12 och vice versa.As mentioned above and as shown in the described the construction, the intermediate part 3 is rotatable between the parts 1 and 2 and in relation to these. The intermediate part 3 can thus. rotated from a position in which its opening 9 is located in the middle of the opening 8 of the part 1, to a position in which the opening 9 is located in the middle of the opening 12 of the part 2 and vice versa.

Om sålunda en burk 18 innehållande exempelvis malt och frys- torkat kaffe är anbragt med sin öppna ände i delens 1 uppåt öppna utrymme 6, kommer detta utrymme att fyllas med en del av burkens innehåll, vilket även fyller det utrymme, som bil- das av öppningen 9 i mellandelen 3, om denna del befinner sig i det vridläge, i vilket öppningen 9 befinner sig mitt för öppningen 8 i den övre delens 1 botten 5. Den nedre delens 2 övre yta utgör emellertid botten för öppningen 9 i delarnas 1-3 nämnda inbördes vridlägen. Om emellertid nu mellandelen 3 vrides från det läge, i vilket öppningen 9 befinner sig mitt för den övre delens 1 öppning 8, och till det vridläge, i vilket öppningen 9 befinner sig mitt för den nedre delens 2 öppning 12, kommer innehållet i öppningen 9 att transpor- teras från läget under öppningen 8 till läget över öppningen 12, genom vilken det rinner ut. Under nämnda transport utgör mellandelens 3 övre yta botten för den övre delens 1 öppning 8 och hindrar utrinning av innehållet i utrymmet 6, samt ut- gör den nedre dulunn 2 övre yta button För öppningen 9, så 452 589 att innehållet i denna kvarhålles, till dess öppningen 9 bör- jar överlappa öppningen 12 och innehållet i den förra börjar rinna ut genom den senare.Thus, if a can 18 containing, for example, malt and frozen dried coffee is placed with its open end in part 1 upwards open space 6, this space will be filled with a part of the contents of the can, which also fills the space provided by the of the opening 9 in the intermediate part 3, if this part is located in the rotational position in which the opening 9 is located opposite the opening 8 in the bottom 5 of the upper part 1. The lower part 2 however, the upper surface forms the bottom of the opening 9 in the parts 1-3 mentioned mutual rotational positions. If, however, now the middle part 3 is rotated from the position in which the opening 9 is located in the middle of the opening 8 of the upper part 1, and to the rotational position, in which the opening 9 is located in the middle of the lower part 2 opening 12, the contents of the opening 9 will be transported from the position below the opening 8 to the position above the opening 12, through which it flows out. During said transport constitute the upper surface of the intermediate part 3 the bottom for the opening of the upper part 1 8 and prevents leakage of the contents of the space 6, as well as make the lower dulunn 2 upper surface button For the opening 9, so 452 589 that its contents are retained until the opening 9 should jar overlap the opening 12 and the contents of the former begin flow out through the latter.

Det är tydligt, att mellandelens 3 höjd och öppningens 9 diameter bestämmer volymen av den kvantitet material, som på det ovan beskrivna sättet satsvis kan avges från den övre delens 1 utrymme 6 (och därmed från burken 18) till mellan- delens 3 öppning 9. De avgivna dosernas storlek kan sålunda lätt bestämmas genom val av dessa parametrar. Exempelvis kan dosernas storlek varieras genom anordnandet av en sats av in- bördes utbytbara mellandelar 3 av olika höjd. Dosens storlek kan enkelt minskas genom insatsringar (icke visat), för in- placering i öppningen 9. Härvid kan den nedre delens 2 öpp- ning 12 ges ett något mindre tvärsnitt än mellandelens öppning 9 för förhindrande av att en i denna inplacerad insatsring faller ned genom öppningen 12. Detta kan även förhindras ge- nom att öppningens 9 periferi förses_med ett steg och insats- ringarna med en motsvarande utbildning av deras ytterperiferi, exempelvis en fläns.It is clear that the height of the intermediate part 3 and the opening 9 diameter determines the volume of the quantity of material, which in the manner described above can be delivered batchwise from the upper the space 6 (and thus from the can 18) of the part 1 to the intermediate opening 3 of the part 9. The size of the delivered doses can thus easily determined by selecting these parameters. For example, can the size of the doses is varied by arranging a batch of interchangeable parts 3 of different heights should be worn. Dose size can be easily reduced by insert rings (not shown), for placement in the opening 9. In this case, the opening of the lower part 2 can be 12 is given a slightly smaller cross-section than the opening of the intermediate part 9 to prevent an insert ring inserted therein falls through the opening 12. This can also be prevented from by providing the periphery of the opening 9 with a step and insert rings with a corresponding education of their outer periphery, for example a flange.

För att anordningen skall arbeta på bekvämt och bestämt sätt är organ anordnade för att ge mellandelen 3 en begränsad, bestämd vridningsvinkel, som motsvarar vridningen mellan det läge, i vilket mellandelens 3 öppning 9 är koaxiell med den övre delens 1 öppning 8, och det läge, i vilket öppningen 9 är koaxiell med den nedre delens 2 öppning 12. I detta syfte är mellandelen 3 försedd med ovannämnda, uppåt öppna och nedåt slutna bågformiga urtag 10. Med detta urtag, eller när- mare bestämt med dess ändväggar, samverkar en från undersidan av den övre delens 1 botten 5 utskjutande tunga 19, som i delarnas 1-3 monteringsläge skjuter ned i urtaget 10. Detta har sådan periferiell längd eller upptager en sådan vinkel och tungan 19 är placerad i ett sådant vinkelläge, att dess i figuren från betraktaren vända yta ligger mot urtagets 10 vänstra ändvägg, då mellandelen 3 intager det vinkelläge, i vilket dess öppning 9 är koaxiell med den övre delens 1 öpp- ning 8. Tungan 19 och urtagets 10 vänstra ändvägg erbjuder sålunda ett bestämt stopp för mellandelens 3 vridrörelse till det läge, i vilket öppningen 9 mottager material från delens 452 589 1 utrymme 6 via öppningen 8.For the device to work on comfortably and firmly means, means are provided for giving the intermediate part 3 a limited, determined angle of rotation, which corresponds to the rotation between it position, in which the opening 9 of the intermediate part 3 is coaxial with it the opening 8 of the upper part 1, and the position in which the opening 9 is coaxial with the opening 12 of the lower part 2 for this purpose the intermediate part 3 is provided with the above-mentioned, upwardly open and downwardly closed arcuate recesses 10. With this recess, or more specifically with its end walls, one interacts from the underside of the bottom 19 projecting tongue 19 of the bottom part 1, as in the 1-3 mounting position of the parts slides down into the recess 10. This has such a circumferential length or occupies such an angle and the tongue 19 is placed in such an angular position that its in the figure facing away from the viewer lies against the recess 10 left end wall, when the intermediate part 3 assumes the angular position, in which its opening 9 is coaxial with the opening of the upper part 1. ning 8. The tongue 19 and the left end wall of the recess 10 offer thus a definite stop for the rotational movement of the intermediate part 3 to the position in which the opening 9 receives material from the part 452 589 1 space 6 via the opening 8.

Vid den visade utföringsformen är vidare i urtaget 10 inlagd ovannämnda tryckspiralfjäder 11. Den är i delarnas mon- teringsläge anordnad att med sin i figuren vänstra ände ligga mot tungans 19 i figuren mot betraktaren vända sida, så att den belastar urtagets 10 vänstra ändvägg mot tungan 19. Då de- len 3 vrides från det läge, i vilket öppningen 9 är koaxiell med öppningen 8, vrides urtagets vänstra ände bort från tungans 19 frånsida och tryckes fjädern 11 samman mot tungans 19 åt- sida. Urtaget 10 har sådan periferiell längd, att sedan fjädern 11 helt tryckts samman mellan tungan 19 och urtagets 10 högra ändvägg till följd av ovannämnda vridning av mellandelen 3, öppningen 12 är koaxiell med öppningen 9. Om i detta läge mel- landelen 3 släppes kommer såsom omedelbart inses fjädern 11 genom det tryck den utövar mot urtagets 10 högra ändvägg att återföra mellandelen 3 till det vridläge, i vilket öppningen 9 är koaxiell med öppningen 8. För underlättande av vridning- en från det läge, i vilket öppningen 9 är koaxiell med öpp- ningen 8, till det läge, i vilket den är koaxiell med öpp- ningen 12, avgivningsläget, är mellandelen 3 försedd med ett handtag 20.In the embodiment shown, the recess 10 is further in the recess The above-mentioned compression coil spring 11 is inserted. arranged to lie with its left end in the figure towards the tongue 19 in the figure facing the viewer, so that it loads the left end wall of the recess 10 against the tongue 19. When the The lever 3 is rotated from the position in which the opening 9 is coaxial with the opening 8, the left end of the recess is turned away from the tongue 19 from the side and the spring 11 is pressed together against the tongue 19 page. The recess 10 has such a circumferential length that then the spring 11 completely compressed between the tongue 19 and the right of the recess 10 end wall due to the above-mentioned rotation of the intermediate part 3, the opening 12 is coaxial with the opening 9. If in this position the land part 3 is released as the spring 11 will be immediately recognized by the pressure it exerts against the right end wall of the recess 10 that return the intermediate part 3 to the rotational position in which the opening 9 is coaxial with the opening 8. To facilitate rotation one from the position in which the opening 9 is coaxial with the opening 8, to the position in which it is coaxial with the opening 12, the dispensing position, the intermediate part 3 is provided with a handle 20.

För att avgivningen från den nedre delens 2 öppning 12 skall försiggå utan att materialet sprides på icke reglerat sätt, omslutes öppningens 12 nedre ände av en kort, konisk, nedåt-radiellt inåt avsmalnande pip 21.In order to release from the opening 12 of the lower part 2 shall take place without the material being spread on unregulated way, the lower end of the opening 12 is enclosed by a short, conical, downward-radially inwardly tapered spout 21.

Den övre delen 1 kan förses med en hållare (icke visad) för väggmontering av anordningen.The upper part 1 can be provided with a holder (not shown) for wall mounting of the device.

Av det ovanstående torde framgå, att i enlighet med syftena uppfinningen erbjuder en samtidigt mycket enkel och mycket tillförlitlig anordning för avgivning av doserade mäng- der massgods.From the above it should appear that in accordance with The objects of the invention offer a simultaneously very simple and very reliable device for delivering dosed quantities there mass goods.
