Description

Anordning ved transportør.
Foreliggende oppfinnelse angår en anordning ved transportbr av "vakuumtypen, hvor et med munnstykke utstyrt bbyelig ror er forbunnet med en vakuumkilde for innsugning av transportgodset og dettes avlevering i en samlebeholder, hvorfra det fores ut ved en transportbrmekanisme. -
Hovedformålet med oppfinnelsen er å tilveiebringe en anordning for hurtig og sikkert å flytte et antall gjenstander fra ét sted til et annet uten å skade gjenstandene og når så bns-kes, flytte gjenstandene mellom adtsRilte nivåer. Et annet formål med oppfinnelsen er å skaffe en anordning av den ovenfornevnte art som er smidig i anvendelse og som kan ta opp gjenstander som! er spredd over en stor flate eller beliggende^på adskilte steder uten at anordningen i sin helhet behbver å flyttes og som dessuten er lett flyttbar fraaen plass til en annen. Det er også et formål med oppfinnelsen å skaffe en anordning av den ovenfornevnte art som overforer gjenstander fra adskilte steder, idet gjenstandene transporteres gjennom anordningen og skylles under passerin--gen gjennom samme.
Disse oppgaver og formål er lost ved hjelp av oppfinnel| sen, idet denne udmérker seg ved at sugeroret er forbundet med j den ovre ende av et vedbunden åpen kammer i et hus som er monter^ på et underliggende vanntank i en slik stilling at kammerets åpn4 bunnparti er senket i en viss dybde under vannets overflate, og j at kammeret er forbundet med en sugevifte ved en gjennom kammerets sidevegg innmunnende ledning. j
- - Oppfinnelsen skal beskrives nærmere under henvisning ti.i<L >tegningene, hvor fig. 1 er et perspektivriss av en anordning ifo.Lge oppfinnelsen montert på en brygge, fig. 2 i stbrre skala et plan-riss av anordningen,.; fig. 3 et lengdesnitt langs linjen 3 - 3 i fig. 2 og fig. k et tverrsnitt i mindre skala langs linjen k - k i fig. 3-På tegningen, betegner 1 en boyelig, lufttett slange til hvis ene ende er festet et munnstykke 2 og som ved den annen end) er forsynt med en flens 3 forbundet med den ovre ende av et ror, som strekker seg gjennom og er fast forbundet med en ovre vegg av et i sin helhet med 5 betegnet hus. Med huset 5 er fast for-i bundet et luftutlbpsror 6, som strekker seg gjennom huset og undlr anordningen med et nedadrettet endeparti 7-Huset har, som det fremgår av fig. k, i tverrsnitt formisn av en omvendt U og innbefatter motstående endevegger 8 og 9 og en med disse fast forbundet kappe 10, som danner husets takpart og sider. En mellomvegg 11 strekker seg tvers over kappens 10 indro parallelt med endeveggene. En bunn 12 strekker seg mellom veggene 9 og 11 tvers over kappen 10 og lukker huset mellom veggene 9 og f
11 slik at der gjenstår en åpning mellom veggene 8 og 11 under kappen. Over bunnen 12 er montert en elektrisk motor 13> som driver endelbse remmer lk, som er fort om på en aksel 15 fast mon-terte remskiver 15a. Akslen 15 er roterbart lagret i stendere 16 og er fast forbundet med viftevinger 17» som er beliggende i jet ringformet hus 18. Et innlbpsrbr 19 strekker seg gjennom veggen i i 11 og huset 18 i aksiell retning av huset 18. Roret 6 er fast forbundet med og fort gjennom husets 18 periferi, for å motta av fra huset utblåst luft.
En elektrisk manbvreringskasse 20 er forbundet med en ikke vist elektrisk strbmkilde og til motoren 13 for dennes manov-reringoog er forsynt med en gjennom en åpning i kappen 10 fbrt manbvreringsspak 21.
Deneene endevegg 22 av en tank er forbundet med et plan-; bunnparti 23, hvorfra et gjenstående parti 24 av tankens bunn strekker.vseg skrått oppad. Bunnen 24 har et skrått nedad ombbyefc kantparti 2§.. En sidevegg 26 strekker seg mellom endeveggen 22 og bunnen 23, 24 og er fast forbundet med disse. En annen sidevegg 27 strekker seg på lignende måte mellom endeveggen 22 og bunnen 23, 24 og er fast forbundet med disse. Endeveggen 22, bunnen 23, 24 samt sideveggene 26 og 27 danner tilsammen en vanntank. Siden 26 heller innad fra den ovre kanten til et vertikale parti 29, og siden 27 heller innad mot et vertikalt parti 28.
En avstivende bjelke 30 er fast forbundet med siden 27 ved dennes overkant, og en lignende bjelke 31 er forbundet med siden 26 ved dennes overkant. Tvers over bjelkene 30 og 31 er anordnet I-bjelker 32 og 33» på hvilke bunnen 12 er montert.
En aksel }"k er dreibart lagret i på tegningene-ikke vis ;e lagre, som bæres av sidepartiene 28 og 29. På akslen 34 er dreif bart lagret kjedehjul 35» over hvilke er fort to kjeder 36 for å drive og bære et endelbst transportbånd 39, som strekker seg mellom de vertikale sideveggpartier 28 og 29. Ved transportbrens motsatte ende er kjedene fort om kjedehjul 37,' som er fast montert på en aksel 38. Denne er dreibart lagret i ikke viste lagres, som bæres av de vertikale sidepartiers 28 og 29 ovre endepartierj aom er innbyrdes forbundet ved-hjelp av et tverrstykke 40. En j til manbvreringskassen 20 forbundet elektrisk motor 41 er montert på tverrstykket 40 og driver en av en rømkapsel 42 dekket, ende-j lbs .r«m, soin er fort om akselen 38 for dennes omdreining i sådan<1 >retning, at transportbåndet 39 drives i retning mot urviaeren.
Et vanntillbpsrbr 43 er forbundet med en._ikke vist trykk-vannskilde og til mellomrommet mellom veggene 8 og 11 for til- ! fbrsel av vann til nevnte mellomrom og til den under samme belig-j gende vanntank. I roret 43 er anordnet en reguleringsventil 44. Anordningen understbttes av en under bunnen 24 anordnet,' vertikal ramme 45. i
Anordningen ifblge oppfinnelsen kan fremstilles i forskjellige stbrrelser for gjenstander av forskjellige typer og stbrrelser, såsom frukt, grbnsaker, fisk, reker og andre natur-produkter såvel som mindre fabrikerte gjenstander. De gjenstan-;
i der som skal flyttes ved hjelp av anordningen, er i stbrrelse bej-grenset bare av munnstykkets 2 stbrrelse og storrelsen av det av! viftevirigene 17 frembragte undertrykk. j
Som eksempel beskrives i det fbigende anvendelsen av en' ifblge oppfinnelsen utfort anordning som transportbr for reker.

Munnstykket 2 kan eksempelvis plasseres i en haug av reker i lasterommet av en ikke vist, langs bryggen A beliggende ! 1 fiskebåt. Ved å sette motorene 13 og 4l igang ved hjelp av manbv-Ireringsspaken 21 settes viftevingene 17 i rotasjon og frembringe^* 1 et undertrykk i roret 19 mellom veggene 8 og 11 samt i slangen li hvorved rekene H vil bli suget inn i munnstykket 2 og gjennom jslangen 1 samt falle mellom veggene 8 og 11 (se fig. 3) ned i 1 vannet G, hvorved rekene havner på transportbåndet 39» og av dette
•transporteres opp til og mates ut ved det ombbyde kantparti 25 aj bunnen 24. |
> 1 Vannet G danner en tetning mot luft mellom veggene 9 og1 II og kappen 10, således at luften fra slangen X gjennom roret 19 går inn i huset 18 og blåses ut gjennom rbrét 6, 7. Rekene kommer av sin egen tyngde til fra slangen 1 å falle ned i vannet jG og havne på transportbåndet 39 hvorved de skylles under foringen igjennom vannet.
Vann G tilfores..fra roret 43 gjennom reguleringsventiler 44, således at dets nivå i den av delene 22 - 29 dannede tank alltid holdes tilstrekkelig hbyt for å tette den åpne bunnside -j av kammeret som dannes av veggene 8 og 11 samt kappen 10... i Oppfinnelsen er ikke begrenset til den bare som eksempel ovenfor beskrevne og på tegningene viste utfbrelsesform, som kan endres i sine detaljer uten at oppfinnelsens grunntanke fragås. ~j
