Description

Nivellerings aggregat med hylster og afgrænset spindelaevind længde samt anvendelseLeveling unit with sleeve and defined spindle thread length and use

Opfindelsen angår er nivellerings aggregat til nivellering og understøttelse af emner, såsom maskiner, hvilket nivellerings aggregat omfatter en toppart til befæstigelse i et emne, såsom en maskine samt en underpart til kontakt mod et fundament såsom et gulv, og hvor der i topparten indgår en spindel, der omfatter et gevind, en nedre endeflade ved underparten og en centerakse, samt et hylster der omfatter en nedre endeflade nærmest underparten, en øvre endeflade i den modsatte ende af hylsteret.The invention relates to a leveling unit for leveling and supporting items such as machines, which leveling unit comprises a top part for fastening in a workpiece such as a machine and a lower part for contact against a foundation such as a floor, and in which the top part includes a spindle , comprising a thread, a lower end surface at the lower part and a center axis, and a sheath comprising a lower end surface closest to the lower part, an upper end surface at the opposite end of the sheath.

Desuden angår opfindelsen anvendelsen af nivellerings aggregatet.In addition, the invention relates to the use of the leveling assembly.

På eksisterende nivellerings aggregater til anvendelse i lokationer med høje krav til hygiejne anvendes i dag typisk et hylster, der monteres ovenfra omkring spindlen, til at afskærme gevindet på spindlen.On existing leveling assemblies for use in locations with high hygiene requirements, today a casing mounted from above around the spindle is typically used to shield the thread on the spindle.

Hylster i denne forbindelse beskriver teknisk en gevindafskærmning. Hylsteret monteres oppefra, da hylsteret typisk monteres efter at topparten er samlet med underparten.The casing in this connection technically describes a threaded shield. The sheath is mounted from above, as the sheath is typically mounted after the top part is assembled with the lower part.

Hylsteret kunne også monteres nedefra, hvis det sker inden topparten samles med underparten og hvis spindlen er indrettet til det.The sleeve could also be mounted from below if it happens before the top part is assembled with the lower part and if the spindle is arranged for it.

Gevindet på spindlen skal dækkes med en afskærmning, da rengøring af et gevind med små kanter og skarpe hjørner er meget vanskelig. Det er desuden et krav at gevindet på spindlen er afskærmet i forbindelse med at opnå myndighedsgodkendelser af nivellerings aggregatet, herunder USDA, EHEDG og 3A godkendelser.The thread on the spindle must be covered with a shield, as cleaning a thread with small edges and sharp corners is very difficult. It is also a requirement that the thread on the spindle is shielded in connection with obtaining regulatory approvals of the leveling unit, including USDA, EHEDG and 3A approvals.

Dette hylster tætner med et nedre tætnings emne nederst mod spindlen under spindlens gevind og øverst med et øvre tætnings emne mod undersiden af et emne, såsom en maskine, der skal understøttes af nivellerings aggregatet, således der ikke kan trænge skidt og bakterier ind til gevindet på spindlen.This sleeve seals with a lower sealing blank at the bottom of the spindle under the thread of the spindle and at the top with an upper sealing blank against the underside of a blank, such as a machine to be supported by the leveling assembly so that dirt and bacteria cannot penetrate the thread of the spindle.

Det vil være beskrevet i en monterings vejledningen, at man ikke må skrue hylsteret så højt op, at den nederste del af gevindet på spindlen bliver synlig.It will be described in the mounting instructions that the sleeve must not be screwed up so high that the lower part of the thread on the spindle becomes visible.

Der er dog visse ulemper ved den kendte teknologi, herunder at det er muligt at skrue hylsteret så langt op at det nederste tætnings emne føres med hylsteret op over gevindet på spindlen og hermed er gevindet på spindlen delvist blotlagt og skidt og bakterier kan trænge ind i gevindet og også op under hylsteret, da det nederste tætningsemne ikke kan tætne mod selve gevindet på spindlen. Dette forekommer på trods af, at det er beskrevet i monteringsvejledningen, at hylsteret ikke må skrues så højt op. Desuden forventes det at myndighedsgodkendelserne af nivellerings aggregatet, herunder ved USDA vil stille krav om at hverken hele gevindet eller dele af gevindet på spindlen må kunne blotlægges ved en eventuel fejl betjening.However, there are certain disadvantages of the known technology, including that it is possible to screw the sheath up so far that the lower sealing member is moved with the sheath up over the thread on the spindle and thus the thread on the spindle is partially exposed and dirt and bacteria can penetrate. the thread and also up under the sheath as the lower sealing member cannot seal against the thread itself on the spindle. This occurs despite the fact that it is described in the installation instructions that the casing must not be screwed up as high. In addition, it is expected that the regulatory approvals of the leveling unit, including by the USDA, will require that neither the entire thread nor parts of the thread on the spindle can be exposed by any improper operation.

DE102007057382 beskriver et nivellerings aggregat af den i indledningen angivne. Det omfatter således et hylster til afskærmning af en spindel. Hylsteret er dog ikke konstrueret, så at en afskærmning af spindlen altid er sikret.DE102007057382 discloses a leveling assembly of the one specified in the preamble. It thus includes a sleeve for shielding a spindle. However, the casing is not designed so that a spindle shield is always secured.

Det er derfor et formål med opfindelsen at anvise et nivellerings aggregat uden ovennævnte ulemper eller i det mindste tilvejebringe et nyttigt alternativ.It is therefore an object of the invention to provide a leveling assembly without the above disadvantages or at least to provide a useful alternative.

Opfindelsens formål tilgodeses ved et nivellerings aggregat af den i indledningen til krav 1 angivne type, som er karakteristisk ved, at nivellerings aggregatet omfatter en udvendig cylindrisk flade mellem gevindet og den nedre endeflade og et indvendigt gevind i et område ved den øvre endeflade, indrettet til at gå i indgreb med gevindet på spindlen og at afstanden fra hylsterets øvre endeflade til hylsterets nedre endeflade er større end længden på spindlens gevind.The object of the invention is met by a leveling unit of the type specified in the preamble of claim 1, characterized in that the leveling unit comprises an outer cylindrical surface between the thread and the lower end surface and an internal thread in a region at the upper end surface, adapted to to engage the thread on the spindle and that the distance from the upper end surface of the sheath to the lower end surface of the sheath is greater than the length of the spindle thread.

På denne måde bliver det således muligt at fremstille et nivellerings aggregatet, hvor hylsteret ikke kan skrues så højt op at hele eller dele af det nederste af spindlens gevind blotlægges.In this way it thus becomes possible to produce a leveling unit where the casing cannot be screwed up so high that all or part of the lower part of the spindle thread is exposed.

Det sikres med opfindelsen at spindlens gevind altid er afskærmet af hylsteret, så længe der er frit gevind i toppen af spindlen til at fastgøre i et emne der skal understøttes.The invention ensures that the threads of the spindle are always shielded by the sleeve as long as there is free thread at the top of the spindle to attach to a workpiece to be supported.

Nivellerings aggregatet, der med sine andre konstruktionsdetaljer, kan anvendes i lokationer med høje krav til hygiejne, kan således fremover også godkendes ved USDA, 3A og EHEDG hvis det indføres som krav hos de pågældende myndigheder at spindlens gevind ikke må kunne blotlægges ved at skrue hylsteret for højt op.The leveling unit, which with its other design details, can be used in locations with high hygiene requirements, can henceforth also be approved by USDA, 3A and EHEDG if it is introduced as requirements of the relevant authorities that the spindle threads must not be exposed by screwing the sheath too high up.

Ved at tilpasse længden på spindlens gevind, således det er kortere end længden på hylsteret med det nedre tætningsemne monteret, sikres hermed at hele eller dele af gevindet på spindlen ikke kan blotlægges ved en fejl.By adjusting the length of the spindle thread so that it is shorter than the length of the sheath with the lower sealing member mounted, it is ensured that all or part of the thread on the spindle cannot be exposed by mistake.

Ved et yderligere aspekt af opfindelsen omfatter nivellerings aggregatet, at det nedre tætningsemne er lavet i et polymert materiale Herved opnås det at der kan tilvejebringes passende tætning mellem spindel og tætningsemne, samt mellem hylster og tætningsemneIn a further aspect of the invention, the leveling assembly comprises that the lower sealing blank is made of a polymeric material, thereby obtaining suitable sealing between spindle and sealing member, as well as between sleeve and sealing member.

Ved et yderligere aspekt af opfindelsen omfatter nivellerings aggregatet, at der på den nedre del af den cylindriske flade på spindlen er to spor, der omfatter en første skruenøgle flade og en anden skruenøgle flade, placeret symmetrisk omkring centeraksen, indrettet til at danne anlæg med en skruenøgle, hvilke to spor er afgrænset i centeraksens retning af en øvre skruenøgleplan og en nedre skruenøgleplan, hvilken nedre skruenøgleplan er placeret nærmere den nedre endeflade på spindlen end den øvre skruenøgleplanIn a further aspect of the invention, the leveling assembly comprises that on the lower portion of the cylindrical surface of the spindle there are two grooves comprising a first wrench surface and a second wrench surface located symmetrically about the center axis, arranged to form abutments with a wrench, which two grooves are bounded in the direction of the center axis by an upper wrench plane and a lower wrench plane, which lower wrench plane is located closer to the lower end surface of the spindle than the upper wrench plane.

Herved opnås det at spindlen kan drejes eller holdes fast med en skruenøgle.This results in the fact that the spindle can be turned or held with a wrench.

Ved et yderligere aspekt af opfindelsen omfatter nivellerings aggregatet, at det indvendige gevind i hylsteret er afgrænset i retning mod hylsterets første endeflade af en nedre afgrænsning, hvilken nedre afgrænsning er tilvejebragt ved overgang mellem hylsterets gevind og en i det væsentlige glat indre flade.In a further aspect of the invention, the leveling assembly comprises that the inner thread of the casing is bounded towards the first end surface of the casing by a lower boundary, which lower boundary is provided by transition between the casing threads and a substantially smooth inner surface.

Herved opnås det at hylsterets indvendige gevind kun har den nødvendige længde.Hereby it is obtained that the inner thread of the sheath has only the required length.

Ved et yderligere aspekt af opfindelsen omfatter nivellerings aggregatet, at spindlens gevind er afgrænset i retning mod spindlens nedre endeflade af en nedre afgrænsning, hvilken nedre afgrænsning er tilvejebragt ved overgang mellem spindlens gevind og den udvendige cylindriske flade på spindlenIn a further aspect of the invention, the leveling assembly comprises that the threads of the spindle are bounded towards the lower end surface of the spindle by a lower boundary which is provided by transition between the threads of the spindle and the outer cylindrical surface of the spindle.

Herved opnås det, at der kan være en cylindrisk flade under afgrænsningen på spindlen, velegnet til at tætne imodHereby it is obtained that there may be a cylindrical surface below the boundary of the spindle, suitable for sealing against

Ved et yderligere aspekt af opfindelsen omfatter nivellerings aggregatet, at afstanden mellem den nedre afgrænsning på hylsterets indvendige gevind og hylsterets nedre tætningsplan er kortere end afstanden fra den nedre afgrænsning på spindlens gevind til den øvre skruenøgleplan på spindlen Herved opnås det, at det nedre tætningsemne på hylsteret ikke kan føres ned forbi de to spor i den cylindriske flade og dermed sikres det, at der ikke opstår en utæthed hvis hylsteret er skruet helt i bund.In a further aspect of the invention, the leveling assembly comprises that the distance between the lower boundary of the inner thread of the sheath and the lower sealing plane of the sheath is shorter than the distance from the lower boundary of the spindle thread to the upper wrench plane of the spindle. the sleeve cannot be passed past the two grooves in the cylindrical surface and thus it is ensured that no leakage occurs if the sleeve is fully screwed in.

Det nedre tætningsemne 14 vil typisk være en o-ring placeret i hylsterets 6 spor 17, men er ikke begrænset til dette og kan i en alternativ udførelse have andre udformninger, herunder være et ringformet emne med en udstrækning på hver side af den nedre endeflade 15 på hylsteret 6, indrettet til at tætne mod spindlens 4 cylindriske flade 10 og mod hylsteret 6, hvor den maksimale udstrækning er afgrænset i retning mod den øvre endeflade 16 på hylsteret af et øvre tætningsplan 20 og i den modsatte retning af et nedre tætningsplan 21The lower sealing member 14 will typically be an o-ring located in the groove 6 of the sleeve 6, but is not limited thereto, and in an alternative embodiment may have other configurations, including an annular member having an extension on each side of the lower end surface 15 on the sheath 6, adapted to seal against the cylindrical surface 10 of the spindle 4 and to the sheath 6, the maximum extent being defined in the direction towards the upper end surface 16 on the sheath of an upper sealing plane 20 and in the opposite direction of a lower sealing plane 21

Det øvre tætningsplan 20 og det nedre tætningsplan 21 er placeret relativ i forhold til den nedre endeflade 15 på hylsteret 6 og følger dermed hylsterets 6 bevægelse.The upper sealing plane 20 and the lower sealing plane 21 are positioned relative to the lower end surface 15 of the sheath 6, thus following the movement of the sheath 6.

I henhold til opfindelsen har det øvre skruenøgleplan 22 på spindlen 4 indflydelse på afskærmningsfunktionen, når hylsteret 6 er skruet helt ned. Hvis det nedre tætningsemne 14 således føres ned forbi det øvre skruenøgleplan 22 og dermed er ud for de to spor 11,12 er der risiko for, at der ikke længere er en tæt pakning mod den cylindriske flade 10 på spindlen 4 og dermed at der kan trænge skidt og bakterier ind under hylsteret 6 og ind til spindlens 4 gevind 5.According to the invention, the upper wrench plane 22 on the spindle 4 has an influence on the shielding function when the casing 6 is fully screwed down. Thus, if the lower sealing blank 14 is passed past the upper wrench plane 22 and thus adjacent to the two grooves 11,12, there is a risk that there is no longer a tight seal against the cylindrical surface 10 of the spindle 4 and thus penetrate dirt and bacteria under the sheath 6 and into the thread 5 of the spindle 4.

Spindlen 4 er ikke begrænset til den her viste udformning med at have en større omkreds ved den nedre endeflade 25, men kan i en anden udførelsesform være indrettet til at den cylindriske flade 10 på spindlen er afgrænset nedad af den nedre endeflade 25 på spindlen og dermed definerer den største omkreds på spindlen 4 mellem spindlens 4 gevind 5 og den nedre endeflade 25. Hermed kan hylsteret 6 alternativt monteres nedefra inden topparten 3 samles med underparten 2.The spindle 4 is not limited to the embodiment shown here, having a larger circumference at the lower end surface 25, but may in another embodiment be arranged so that the cylindrical surface 10 of the spindle is bounded downward by the lower end surface 25 of the spindle and thus defines the largest circumference of the spindle 4 between the threads 5 of the spindle 4 and the lower end surface 25. Hereby, the sheath 6 can alternatively be mounted from below before the top part 3 is assembled with the lower part 2.

På fig 6 vises at når hylsteret 6 er skruet helt op på spindlen 4, så der ikke er frit gevind 5 i toppen af spindlen 4, så er hele spindlens 4 gevind 5 afskærmet af hylsteret 6.In Figure 6 it is shown that when the sleeve 6 is screwed all the way up to the spindle 4 so that there is no free thread 5 at the top of the spindle 4, then the entire thread 5 of the spindle 4 is shielded by the sleeve 6.

I et nivellerings aggregat 1 ifølge opfindelsen er det således ikke muligt at blotlægge hele eller dele af det nederste af spindlens 4 gevind 5 ved en fejl, når hylsteret 6 skrues op for at tætne mod det emne, der skal understøttes. Ved at tilpasse længden på spindlens 4 gevind 5, således det er kortere end den totale længde på hylsteret 6, sikres det at spindlens 4 gevind 5 er afskærmet, så længe der er gevind 5 i toppen af spindlen 4 til at fastgøre et emne, der skal understøttes.Thus, in a leveling assembly 1 according to the invention, it is not possible to expose all or part of the lower part of the thread 5 of the spindle 4 by mistake when the casing 6 is unscrewed to seal against the workpiece to be supported. By adjusting the length of the thread 5 of the spindle 4 so that it is shorter than the total length of the sleeve 6, it is ensured that the thread 5 of the spindle 4 is shielded as long as there is thread 5 in the top of the spindle 4 to secure a workpiece which must be supported.

Dermed kan de forventede fremtidige krav fra myndigheder opfyldes og myndighedsgodkendelserne, herunder fra USDA opnås.Thus, the expected future requirements from authorities can be met and government approvals, including from the USDA, are obtained.

Det er en del af opfindelsen at det beskrevne nivellerings aggregat 1 anvendes i lokationer med høje krav til hygiejne såsom lokationer til forarbejdning af fødevarer eller fremstilling af medicin.It is part of the invention that the leveling assembly 1 described is used in locations with high hygiene requirements such as food processing or medicine manufacturing locations.
