En enhed til dossering af et materiale samt anvendelse heraf Frembringelsens anvendelsesområdeA device for dosing a material and its use The scope of production
Den foreliggende frembringelse angår en enhed til dossering af et materiale, såsom en gødningsspreder, ifølge indledningen af krav 1, samt anvendelse heraf.The present invention relates to a unit for dosing a material, such as a fertilizer spreader, according to the preamble of claim 1, as well as its use.
Teknikkens standpunktThe prior art
Korrekt dosering af materialer som handelsgødning, såsæd, salt, gylle eller pesticider på landbrugsjord eller lignende er vigtig af flere grunde. Blandt andet kan over- eller underdosering føre til øgede omkostninger, øget miljøbelastning eller dårlige virkningsgrader.Proper dosing of materials such as commercial fertilizers, seeds, salt, manure or pesticides on agricultural land or the like is important for several reasons. Among other things, over- or under-dosage can lead to increased costs, increased environmental impact or poor efficiencies.
Det er derfor kendt at udstyre f.eks. lifthængte gødningsspredere med vejeudstyr, der løbende under spredningen af handelsgødningen kan veje den resterende mængde gødning i sprederens gødningsbeholder. I praksis gøres dette ved at ophænge beholderen, hvorfra gødningen spredes, i en stangvejecelle i hvert af beholderens fire hjørner i bunden. Jo mere stangvejecelleme nedbøjes, jo større vægt. Vejecelleme kan så kobles til en computer, der igen er forbundet til midler på sprederen, der kan styre doseringen. Via en computer har man mulighed for, at indtaste den mængde gødning man ønsker spredt pr. hektar. Via oplysninger fra traktoren eller fra GPS kender computeren den tilbagelagte strækning og kan derved indstille den nøjagtige dosering ved en given fremdriftshastighed. Men da gødningen kan have varierende beskaffenhed, er det nødvendigt løbende at kontrollere, at den ønskede mængde nu også ret faktisk er fjernet fra beholderen, og derfor er det fordelagtigt løbende at veje den resterende mængde materiale i beholderen.It is therefore known to equip e.g. Lift-mounted fertilizer spreaders with weighing equipment that can continuously weigh the remaining amount of fertilizer in the spreader's fertilizer container during the spread of the commercial fertilizer. In practice, this is done by hanging the container from which the fertilizer is spread, into a rod weighing cell in each of the four corners of the container at the bottom. The more barbell cells deflect, the greater the weight. The weighing cells can then be connected to a computer, which in turn is connected to means on the spreader that can control the dosage. Through a computer you have the opportunity to enter the amount of fertilizer you want spread per day. acres. Via information from the tractor or from the GPS, the computer knows the distance traveled and can thus adjust the exact dosage at a given speed of progress. However, since the fertilizer can be of varying nature, it is necessary to continuously check that the desired quantity is now quite effectively removed from the container and therefore it is advantageous to continuously weigh the remaining amount of material in the container.
Lignende vejesystemer findes eller kunne med fordel anvendes f.eks. i forbindelse med såmaskiner, gyllenedfældere, saltspredere, sprøjteudstyr eller andre aggregater, der bruger til at uddosere en fast mængde materiale over et givent areal.Similar weighing systems exist or could advantageously be used e.g. in connection with seed drills, slurry sprayers, salt spreaders, spraying equipment or other aggregates which use to dispense a fixed amount of material over a given area.
2 2DK 2005 00256 U32 2GB 2005 00256 U3
Ulempen ved at veje det resterende materialet på denne måde er dog, at måleusikkerhed ved vejningen er betydelig, når vejningen foregår, hvor enheden med vejeudstyret ikke er vandret. Dette er et ofte forekommende problem, da enheden f.eks. skal bruges til at dosere materialet på marker eller andre større jordarealer, og derfor ofte køres i kuperet terræn enten ved egen drift eller påsat et køretøj, såsom en traktor.However, the disadvantage of weighing the remaining material in this way is that measurement uncertainty in weighing is significant when weighing takes place where the unit with the weighing equipment is not horizontal. This is a common problem as the device e.g. should be used for dosing the material on fields or other major land areas, and therefore are often driven on hilly terrain either on their own or on a vehicle such as a tractor.
Det er derfor et formål med frembringelsen at tilvejebringe en enhed til vejning af materiale, hvor vejningens måleusikkerhed er mindre følsom overfor ændringer i tyngdekraftens indfaldsretning.It is therefore an object of the invention to provide a unit for weighing material where the measurement uncertainty of the weighing is less sensitive to changes in the direction of gravity.
FrembringelsenThe creation
Opfindelsen angår en enhed til dossering af et materiale, såsom en gødningsspreder. Enheden omfatter en beholder for materialet og udstyr til vejning af materialet i beholderen, hvor nævnte udstyr omfatter mindst to individuelle vejeceller. Enheden er ny ved, at de individuelle vejeceller i deres langsgående retning er placeret i en indbyrdes vinkel forskellig fra 180°.The invention relates to a unit for dosing a material, such as a fertilizer spreader. The unit comprises a container for the material and equipment for weighing the material in the container, said equipment comprising at least two individual weighing cells. The unit is new in that the individual weighing cells in their longitudinal direction are at an angle different from 180 °.
Det er fordelagtigt at udstyre en enhed med mindst to individuelle vejeceller, idet det herved er muligt at konstruere en stabil enhed med en god vægtfordeling. Derudover er det fordelagtigt at vejecelleme er placeret i en indbyrdes vinkel, der er forskellig fra 180°, idet måleusikkerheder reduceres betydeligt, når der vejes i situationer, hvor enheden ikke befinder sig på et vandret underlag.It is advantageous to equip a unit with at least two individual weighing cells, since it is possible to construct a stable unit with a good weight distribution. In addition, it is advantageous for the weighing cells to be located at an angle different from 180 °, since measurement uncertainties are significantly reduced when weighed in situations where the unit is not on a horizontal surface.
Vejeceller til dette formål er typisk vandret monterede stangvejeceller, der måler beholderens vægt ved, at lasten skaber en udbøjning af vejecelleme, der registreres af et antal strain-gauge i vejecellen. Hvis enheden kører i kuperet terræn, hvor vejecelleme ikke længere har deres langstrakte retning vinkelret på tyngdekraftens retning, mens der vejes, så vil en del af lasten resultere i træk eller tryk af 3 3DK 2005 00256 U3 stangvejecelleme, hvorfor vejningen bliver mere upræcis. Dette skyldes, at jo stejlere bakke enheden forcere mens der vejes, jo længere fra vinkelret på tyngdekraftens retning vil vejecellemes langstrakte retning bevæge sig.Weighing cells for this purpose are typically horizontally mounted rod weighing cells which measure the weight of the container in that the load creates a deflection of the weighing cells which is detected by a number of strain gauge in the weighing cell. If the unit runs in hilly terrain where the weighing cells no longer have their elongated direction perpendicular to the direction of gravity while weighing, then part of the load will result in the drag or pressure of the 3 3DK 2005 00256 U3 rod weighing cells, which is why the weighing becomes more imprecise. This is because the steeper the hill unit accelerates while being weighed, the farther from the perpendicular to the direction of gravity the elongated direction of the weighing cells will move.
Ved f.eks. at montere fire vejeceller, der parvis overfor hinanden peger nedad mod hinanden i en 10° vinkel i deres langsgående retning, vil en del af lasten fra beholderen resultere i træk i alle stængerne, mens enheden står i vandret. Dette gør, at de registrerer en lavere vægt, end hvis de var vandrette. Men dette kan der kalibreres for, så måleusikkerheden er meget lille, når enheden bevæger sig i et vandret plan, selvom vejecellers langstrakte retning ikke er vinkelret på tyngdekraftens indfaldsretning.For example, mounting four weighing cells facing each other in pairs downwards at a 10 ° angle in their longitudinal direction, a portion of the load from the container will result in pulling in all the rods while the unit is horizontal. This makes them detect a lower weight than if they were horizontal. However, this can be calibrated for, so the measurement uncertainty is very small when the unit moves in a horizontal plane, even though the elongated direction of the weighing cells is not perpendicular to the direction of gravity.
Fordelen ved at montere i en vinkel er så, at når beholderens vægt skal vejes, mens enheden bevæger sig opad en bakke i kørselsretningen, f.eks. hvis en traktor med en gødningsspreder kører op af en bakke på en mark, så vil det være sådan, at lige så meget som de to vejeceller, der peger nedad mod kørselsretningen, bevæger sig væk fra vandret, ligeså meget vil de to andre vejeceller nærme sig vandret.The advantage of mounting at an angle is such that when the weight of the container has to be weighed while the unit moves up a hill in the direction of travel, e.g. if a tractor with a fertilizer spreader drives up from a hill onto a field, then it will be that just as much as the two weighing cells pointing downwards towards the direction of travel move away from the horizontal, as much as the other two weighing cells will approach be horizontal.
Med andre ord kan man sige, at er traditionelt system med vandrette vejeceller måler fejlfrit mens enheden bevæges i det vandrette plan, men jo mere enheden bevæger sig væk fra dette plan, jo større fejl er der på vejningen, hvorved måleusikkerheden øges. Ved er system ifølge frembringelsen tilfører man alle vejecelleme er kendt fejl, som der kan kompenseres for, så måleusikkerheden ikke øges, og ved kørsel i kuperet terræn vil denne fejl øges på to af vejecelleme, lige så meget som den mindskes på to andre, hvorved den samlede fejl er konstant, og derved er måleusikkerheden også i det væsentlige konstant.In other words, one can say that traditional horizontal weighing system measures flawlessly as the unit moves in the horizontal plane, but the more the device moves away from this plane, the greater the error on the weighing, thereby increasing measurement uncertainty. By system, according to the production, all known load cells give rise to known errors that can be compensated for, so that measurement uncertainty does not increase, and when driving in hilly terrain this error will increase on two of the weighing cells, as much as it decreases on two others, thereby the total error is constant, and thus the measurement uncertainty is also substantially constant.
Der gøres opmærksom på, at nævnte materiale omfatter alle materialer man kan ønske doseret nøjagtigt under uddosering, såsom handelsgødning, såsæd, kalk, salt, ukrudts-, sygdoms- eller skadedyrsbekæmpelsesmidler, gylle eller andet.It is to be noted that said material includes all materials that may be accurately dosed accurately during dosing, such as commercial fertilizers, seeds, lime, salt, herbicides, disease or pesticides, manure or other.
4 4DK 2005 00256 U34 4GB 2005 00256 U3
Endvidere gøres der opmærksom på at udover en gødningsspreder kunne nævnte enhed være en gyllenedfælder, en kalk- eller saltspreder, marksprøjteudstyr, en såmaskine eller andet udstyr der bruges til at uddosere en korrekt mængde materiale over et givent areal, typisk et jordbrugsareal.Furthermore, it is noted that in addition to a fertilizer spreader, said unit could be a slurry trap, a lime or salt spreader, field spraying equipment, a drill or other equipment used to dispense a correct amount of material over a given area, typically an agricultural area.
Et aspekt af opfindelsen er, at nævnte indbyrdes vinkel er mellem 50° og 178°, foretrukket mellem 85° og 175° og mest foretrukket mellem 120° og 170°, såsom 160°.One aspect of the invention is that said mutual angle is between 50 ° and 178 °, preferably between 85 ° and 175 °, and most preferably between 120 ° and 170 °, such as 160 °.
Jo større den indbyrdes vinkel er, jo mere reduceres vejecellemes effektivitet. Jo mindre vinklen er, jo dårligere bliver vejecelleme til indbyrdes at kompensere for uhensigtsmæssige lastretninger, hvorved måleusikkerheden øges.The larger the angle between them, the more the efficiency of the weighing cells is reduced. The smaller the angle, the poorer the weight cells become to compensate for inappropriate loading directions, thereby increasing the measurement uncertainty.
De nævnte vinkelområder er derfor udtryk for et fordelagtigt forhold mellem vejecellemes effektivitet, og deres evne til at veje med lav måleusikkerhed.The said angular ranges therefore represent an advantageous relationship between the efficiency of the weighing cells and their ability to weigh with low measurement uncertainty.
Et aspekt af opfindelsen er, at nævnte mindst to individuelle vejeceller er stangvejeceller med en vejekapacitet på op til tre tons.One aspect of the invention is that said at least two individual weighing cells are rod weighing cells with a weighing capacity of up to three tons.
Det er fordelagtigt, at anvende stangvejeceller til indbygning i en enhed ifølge frembringelsen, idet stangvejeceller er relativt billige, driftsikre og velafprøvede inden for dette felt. Derudover er det fordelagtigt, at stangvejecelleme kan have en vejekapacitet på op til tre tons, idet stangvejeceller over denne grænse bliver relativt dyre, hvorfor det økonomiske er mere fordelagtigt evt. at anvende flere ”små” vejeceller end få "store”.It is advantageous to use rod weighing cells for incorporation into a unit according to the invention, since rod weighing cells are relatively inexpensive, reliable and well-tested in this field. In addition, it is advantageous that rod weighing cells can have a weighing capacity of up to three tons, since rod weighing cells above this limit become relatively expensive, which is why the economical is more advantageous. to use more "small" weighing cells than few "large" ones.
Et aspekt af opfindelsen er, at nævnte individuelle vejeceller er placeret omkring er indbyrdes symmetriplan.An aspect of the invention is that said individual weighing cells are located about each other symmetry plane.
5 5DK 2005 00256 U35 5DK 2005 00256 U3
Det er fordelagtigt, at vejeceller er placeret omkring er indbyrdes symmetriplan, idet det hermed er muligt, at lade vejecelleme indbyrdes kompensere for de uhensigtsmæssige lastretninger kørsel i kuperet terræn påvirker vejecelleme med.It is advantageous that weighing cells located around each other are symmetry plane, as it is possible that allowing the weighing cells to compensate for the inappropriate load directions driving in hilly terrain affects the weighing cells with.
Et aspekt af opfindelsen er, at nævnte indbyrdes symmetriplan i det væsentlige er vinkelret på kørselsretningen under uddosering af nævnte materiale.An aspect of the invention is that said mutual symmetry plane is substantially perpendicular to the direction of travel during dosing of said material.
Herved opnås en fordelagtig vægtfordeling på vejecelleme og dermed en mere nøjagtig vægtmåling.This results in an advantageous weight distribution on the weighing cells and thus a more accurate weight measurement.
Et aspekt af opfindelsen er, at nævnte enhed vejer nævnte materiale, mens nævnte enhed er i bevægelse.One aspect of the invention is that said unit weighs said material while said unit is in motion.
Det er fordelagtigt, at enheden vejer materialet kontinuerligt under kørslen, idet det gør enheden tidsmæssigt mere effektiv til uddosering af materialet, end hvis vejningen kun kunne forgå i stilstand.It is advantageous that the unit weighs the material continuously during travel, as it makes the unit more efficient for dosing the material over time than if the weighing could only go to a standstill.
Et aspekt af opfindelsen er, at nævnte langsgående retning er defineret ved et plan gående gennem nævnte vejecellers mindst ene første fikseringspunkt og nævnte vejecellers mindst ene andet fikseringspunkt.An aspect of the invention is that said longitudinal direction is defined by a plane passing through said weighing cell at least one first fixing point and said weighing cell at least one second fixing point.
Herved opnås en fordelagtig udførelse af frembringelsen.Hereby an advantageous embodiment of the production is obtained.
Et aspekt af opfindelsen er, at nævnte enhed er indrettet til påmontage på et køretøj, såsom en traktor.An aspect of the invention is that said unit is adapted for mounting on a vehicle such as a tractor.
Der er fordelagtigt at indrette enheden til montage på et køretøj, idet man herved undgår et skulle indkooperere fremdriftsmidler i enheden, hvorved enhedens fremstillingsomkostninger reduceres.It is advantageous to arrange the unit for mounting on a vehicle, thereby avoiding the need to purchase propellants in the unit, thereby reducing the unit's manufacturing costs.
6 6DK 2005 00256 U36 6GB 2005 00256 U3
Et aspekt af opfindelsen er, at nævnte vejeceller er orienteret, så deres langstrakte retning i det væsentlige er parallel med kørselsretningen under uddosering af nævnte materiale.An aspect of the invention is that said weighing cells are oriented so that their elongated direction is substantially parallel to the direction of travel during dosing of said material.
Landbrugskøretøjer og andre køretøjer, i forbindelse med hvilke frembringelsen kunne tænkes anvendt, er typisk væsentlig længere end de er brede, hvorfor man oftest vælger at forcere bakker op og ned i stedet for på tværs, så risikoen for at vælte reduceres. Det er derfor fordelagtigt, at montere vejecelleme så de er orienteret med deres langstrakte retning i det væsentlige parallel med kørselsretningen under uddosering af materialet, da de derfor er bedre til at kompensere for fejl, når de bevæges væk fra vandret i kørselsretningen.Agricultural vehicles and other vehicles for which the generation could be used are typically much longer than they are wide, which is why one usually chooses to climb hills up and down instead of across, reducing the risk of tipping over. Therefore, it is advantageous to mount the weighing cells so that they are oriented with their elongate direction substantially parallel to the direction of travel during dosing of the material, as they are therefore better at compensating for errors as they move away from the horizontal in the direction of travel.
Et aspekt af opfindelsen er, at nævnte enhed omfatter mindst fire individuelle vejeceller.An aspect of the invention is that said unit comprises at least four individual weighing cells.
Det er fordelagtigt at anvende fire vejeceller, idet det derved er muligt at konstruere en stabil enhed med en god vægtfordelingIt is advantageous to use four weighing cells, since it is possible to construct a stable unit with a good weight distribution.
Frembringelsen angår endvidere en anvendelse af en enhed ifølge krav 1 til 10 i forbindelse med landbrugsudstyr, såsom gødningsspredere, kalkspredere, sprøjteudstyr, saltspredere, såmaskiner og gyllespredere.The production further relates to the use of a unit according to claims 1 to 10 in connection with agricultural equipment, such as fertilizer spreaders, lime spreaders, spraying equipment, salt spreaders, seeding machines and manure spreaders.
Det er fordelagtigt at anvende en enhed ifølge frembringelsen i forbindelse med landbrugsudstyr, idet landbrugsudstyr skal kunne anvendes i kuperet terræn.It is advantageous to use a device according to the production in connection with agricultural equipment, since agricultural equipment must be able to be used in hilly terrain.

Detailed description
Fig. 1 viser et eksempel på en gødningsspreder 1 omfattende et traditionelt vejesystem 2 påsat en traktor 3 som set fra siden.FIG. 1 shows an example of a fertilizer spreader 1 comprising a traditional weighing system 2 mounted on a tractor 3 as seen from the side.
En almindelig kendt enhed 1, såsom den viste gødningsspreder 1 til dosering af et materiale såsom handelsgødning, består af en beholder 5, hvori gødningen, der skal doseres, placeres. Nær beholderens yderperiferi i bunden 6 er beholderen 1 fikseret til et første fikseringspunkt 7 i den ene ende af et antal langstrakte vejeceller 8.1 den anden ende i vejecellemes 8 langstrakte retning L er vejecelleme 8 fastgjort til en bæreramme 10 igennem deres andet fikseringspunkt eller punkter 9.A commonly known unit 1, such as the fertilizer spreader 1 shown for dosing a material such as commercial fertilizer, consists of a container 5 in which the fertilizer to be dosed is placed. Near the outer periphery of the container at the bottom 6, the container 1 is fixed to a first fixing point 7 at one end of a plurality of elongate weighing cells 8.1 the other end in the elongated direction L of the weighing cells 8, the weighing cells 8 are attached to a support frame 10 through their second fixing point or points 9.
Bærerammen er via et liftsystem monteret på en traktor 3, der kan bevæge enheden 1 rundt på det jordareal, hvorpå materialet 4 skal uddoseres.The support frame is mounted via a lift system on a tractor 3 which can move the unit 1 around the ground area on which the material 4 is to be dispensed.
Fig. 2 illustrere et udsnit af en enhed 1 ifølge frembringelsen som set fra siden. I denne udførelse af frembringelsen er vejecelleme 8 ligesom ved traditionelle vejesystemer 2 monteret, så vejecellemes første fikseringspunkt 7 er fikseret til en beholder 5, der i det væsentlige er placeret over vejecelleme 8. Vejecellemes 8 andet fikseringspunkt 9 er fastgjort til en bæreramme 10.FIG. 2 illustrates a section of a unit 1 according to the invention as seen from the side. In this embodiment of the generation, the weighing cells 8 are mounted, as with traditional weighing systems 2, so that the first fixing point 7 of the weighing cells is fixed to a container 5 which is substantially located above the weighing cells 8. The second fixing point 9 of the weighing cells 8 is attached to a support frame 10.
Vejecelleme 8 er fastgjort til bærerammen 10 på en sådan måde, at de i deres langsgående retning L beskriver en indbyrdes vinkel V, der er forskellig fra 180°. IThe weighing cells 8 are attached to the support frame 10 in such a way that they describe in their longitudinal direction L an angle V different from 180 °. IN
8 8DK 2005 00256 U3 dette tilfælde er denne vinkel V 160°, men kunne i en anden udførelse af frembringelsen være både større eller mindre.8 8GB 2005 00256 U3 in this case, this angle is V 160 °, but in another embodiment of the production could be both larger or smaller.
Endvidere er vejecelleme 8 i denne udførelse af frembringelsen placeret symmetrisk omkring et indbyrdes symmetriplan S, der i det væsentlige er lodret, og som i det væsentlige går gennem midten af beholderen 5. I en anden udførelse kunne af frembringelsen kunne vejecelleme 8 dog være monteret asymmetrisk, f.eks. hvis de ikke var monteret i samme vinkel V, eller hvis de ikke var monteret i samme niveau.Further, in this embodiment of the weighing cells 8, the weighing cells 8 are located symmetrically about a substantially vertical symmetry plane S which extends substantially through the center of the container 5. In another embodiment, however, the weighing cells 8 could be mounted asymmetrically , eg. if they were not mounted at the same angle V or if they were not mounted at the same level.
I denne udførelse af frembringelsen er enheden 1 et aggregat, der ikke selv omfattede fremdriftsmidler, men skal monteres på et køretøj for at kunne virke efter hensigten. Det kunne f.eks. være en gødningsspreder, en såmaskine, en gyllenedfælder eller andet, der blev monteret efter en traktor 3.In this embodiment of the device, the unit 1 is an assembly which did not include propulsion means, but must be mounted on a vehicle in order to function as intended. It could, for example. be a fertilizer spreader, a seed drill, a manure trap or other that was fitted to a tractor 3.
I en anden udførelse af frembringelsen kunne enheden 1 omfatte fremdriftsmidler, så enheden 1 var selvkørende på den jord, hvor materialet skal spredes, sås, nedfældes, udsprøjtes eller andet.In another embodiment of the production, the unit 1 could comprise propellants so that the unit 1 was self-propelled on the soil where the material is to be spread, sown, deposited, sprayed or otherwise.
Fig. 3 viser et forstørret udsnit af det udsnit, der er vist på fig. 2.FIG. 3 shows an enlarged section of the section shown in FIG. 2nd
Vejecellen 8 er i sit første fikseringspunkt 7 fikseret indirekte til beholderen 5 gennem et aflangt gennemgående spor på et eller flere beholderbeslag 12. Ved at fastgøre vejecellen på denne måde, sikres det, at vejecellen kan forskydes en smule i sin langsgående retning L, og at den kan rotere en smule omkring sit første fikseringspunkt 7. Dette sikre at vejecellen 8 mere eller mindre frit kan udbøje, når den påvirkes af en last. Endvidere minimere denne ophængningsform risikoen for, at de forskellige dele, vejesystemet 2 består af, bliver udsat for skadelige laster eller spændinger, der blandt andet kan opstå på grund af den varierende vægt af beholderen 5, alt efter om den er fuld eller tom.The weighing cell 8 is fixed in its first fixing point 7 indirectly to the container 5 through an elongated through groove on one or more container brackets 12. By attaching the weighing cell in this way, it is ensured that the weighing cell can be slightly displaced in its longitudinal direction L and that it can rotate slightly around its first fixing point 7. This ensures that the weighing cell 8 can more or less freely bend when affected by a load. Furthermore, this suspension form minimizes the risk of the various parts of the weighing system 2 being exposed to harmful loads or stresses which may, among other things, be caused by the varying weight of the container 5, depending on whether it is full or empty.

Vejecellen 8 er i denne udførelse af frembringelsen udformet som et langstrakt kvadrat eller rektangel, hvor L på fig. 3 indikerer vejecellens langstrakte retning L. Fig. 4 viser et udsnit at en enhed 1 ifølge frembringelsen som set fra oven, hvor pilen indikerer enhedens 1 normale bevægelsesretning K under uddosering af materiale 4 5 fra beholderen 5.In this embodiment of the weighing cell 8, the weighing cell 8 is formed as an elongated square or rectangle, where L in FIG. 3 indicates the elongated direction of the weighing cell L. FIG. 4 is a sectional view of a unit 1 according to the invention as seen from above, with the arrow indicating the normal direction K of the unit 1 during dispensing of material 45 from the container 5.
