Description
Foreliggende oppfinnelse angår en maskin for sortering av The present invention relates to a machine for sorting
fisk og særlig for sortering av fisk etter tykkelse. For dette formål er det tidligere kjent maskiner omfattende en stort sett V-formet renne hvis skrå sidevegger er dannet av transportbånd e.l. og hvor det mellom de nedre kanter av rennens sidevegger er en spalte med økende bredde i frem-føringsretningen. En sorteringsmaskin av denne art virker slik at fisken under fremføringen etter hvert kommer til et sted i rennen hvor spalten har tilstrekkelig bredde til at fisken kan falle ned gjennom den. En liten eller tynn fisk vil således falle ned på et tidligere tidspunkt enn en stor eller tykk fisk. fish and especially for sorting fish according to thickness. For this purpose, there are previously known machines comprising a largely V-shaped chute whose inclined side walls are formed by conveyor belts or the like. and where between the lower edges of the chute's side walls there is a gap of increasing width in the forward direction. A sorting machine of this kind works in such a way that, during the conveyance, the fish eventually reaches a place in the chute where the gap has sufficient width for the fish to fall through it. A small or thin fish will thus fall down at an earlier time than a large or thick fish.
Dersom fisk ligger mer eller mindre oppe på hverandre i rennen, vil sorteringsresultatet bli mindre godt. En liten eller mellomstor fisk vil nemlig kunne presses gjennom spalten på If fish lie more or less on top of each other in the chute, the sorting result will be less good. A small or medium-sized fish will be able to squeeze through the slot
et for tidlig tidspunkt hvis en stor fisk 'hviler på den lille eller mellomstore fisk, og omvendt kan en liten fisk ride på too early a time if a large fish 'rests on the small or medium-sized fish, and vice versa a small fish can ride on
en større og derved komme for langt i rennen før den faller ned. a larger one and thereby get too far into the chute before it falls down.
Foreliggende oppfinnelse går ut på å overvinne denne ulempe. Dette kunne være ordnet ved å sørge for enkeltvis fremføring The present invention aims to overcome this disadvantage. This could be arranged by providing individual performances
av fisken til sorteringsrennen f .eks., ved å .a/ivende en spesiell -fiskemater eller ved a redusere tilførselsmengden så meget at fisk bare ytterst sjelden ville ligge oppå hverandre. Begge disse måter fører imidlertid til andre ulemper som f.eks. nedsatt sorteringskapasitet. of the fish to the sorting chute, for example, by using a special fish feeder or by reducing the supply quantity so much that fish would only very rarely lie on top of each other. However, both of these ways lead to other disadvantages such as e.g. reduced sorting capacity.
Det er også kjent maskiner for sortering av gjenstander, omfattende transportbånd som løper på skrå oppover, men ved disse maskiner danner ikke transportbåndet eller -båndene noen renne, idet sorteringen skjer ved hjelp av avvisere e.l. Endelig er det kjent sorteringsmaskiner omfattende transportbånd som løper horisontalt, og hvor det mellom par av transportbåndene er en spalte med økende bredde. There are also known machines for sorting objects, comprising conveyor belts that run at an angle upwards, but with these machines the conveyor belt or belts do not form any chute, as the sorting takes place with the help of deflectors etc. Finally, there are known sorting machines comprising conveyor belts that run horizontally, and where there is a gap of increasing width between pairs of the conveyor belts.
Foreliggende oppfinnelse går ut på en sorteringsmaskin av den innledningsvis nevnte art hvor ulempene ved de tidligere kjente maskiner er overvunnet og kapasiteten med hensyn til sortering er øket. The present invention concerns a sorting machine of the type mentioned at the outset where the disadvantages of the previously known machines have been overcome and the capacity with regard to sorting has been increased.
Oppfinnelsen består i en kombinasjon av følgende i og for seg kjente trekk: at den omfatter en stort sett V-formet renne hvis skrå sidevegger er dannet av transportbånd e.l., at V-rennen er orientert på skrå oppover sett fra innløpsenden, fortrinnsvis under en vinkel på 10 - 45°, og at det mellom de nedre kanter på rennens sidevegger er en spalte med økende bredde i frem-før i ngs retn i ngen . The invention consists in a combination of the following per se known features: that it comprises a largely V-shaped chute whose inclined side walls are formed by conveyor belts etc., that the V chute is oriented obliquely upwards as seen from the inlet end, preferably at an angle of 10 - 45°, and that between the lower edges of the gutter's side walls there is a gap with increasing width in the forward direction.
Ved at sorteringsrennen orienteres slik som angitt, vil fisken transporteres oppover under sorteringsprosessen. Fisk som ligger oppe på annen fisk vil da ha en tendens til å gli bak-, over i forhold til den underliggende fisk fordi denne som følge av kilevirkningen vil ligge i et forholdsvis fast grep mellom transportbåndene mens den øvre fisk vil ligge mer fritt. By orienting the sorting chute as indicated, the fish will be transported upwards during the sorting process. Fish that are on top of other fish will then tend to slide backwards, over in relation to the underlying fish because, as a result of the wedge effect, this will lie in a relatively firm grip between the conveyor belts, while the upper fish will lie more freely.
Ved bruk av en sorteringsmaskin i henhold til oppfinnelsen vil éet oppnås ytterligere en fordel. Under sorterings-.spalten er det anordnet skillevegger som bestemmer sorterings-* «grensene. Dersom en fisk" treffer 'en slik skillevegg, oppstår det et støt som vil kunne skade fisken. Når rennen skråstil-les, som foreslått ved foreliggende oppfinnelse, vil fiskens bevegelsesenergi i støtøyeblikket være betydelig redusert, og ødeleggelsen av fisken vil derfor bli mindre betydningsfull. By using a sorting machine according to the invention, a further advantage will be achieved. Beneath the sorting column, partitions are arranged which determine the sorting* "boundaries". If a fish "hits" such a dividing wall, an impact occurs which could damage the fish. When the chute is inclined, as proposed by the present invention, the fish's kinetic energy at the moment of impact will be significantly reduced, and the destruction of the fish will therefore be less significant .
Vedfoyde tegning viser skjematisk en sorteringsmaskin i henhold til oppfinnelsen, i sideriss (fig. 1), grunnriss (fig. 2) og enderiss (fig. 3). Sorteringsmaskinen omfatter Bn stort sett V-formet renne hvis skrå sidevegger er dannet av transportbånd 1 og 2 e.l. Mellom de nedre kanter av rennens sidevegger 1 og 2 er det en spalte 3 med økende bredde i frem-føringsretningen, antydet med en pil i fig. 2. Under spalten The attached drawing schematically shows a sorting machine according to the invention, in side view (fig. 1), ground view (fig. 2) and end view (fig. 3). The sorting machine comprises Bn a mostly V-shaped chute whose inclined side walls are formed by conveyor belts 1 and 2 and so on. Between the lower edges of the chute's side walls 1 and 2, there is a gap 3 with increasing width in the forward direction, indicated by an arrow in fig. 2. Under the column
3 er det anordnet et antall skillevegger 4 som står på 3, a number of partitions 4 are arranged which stand on
tvers av spaltens lengderetning, og mellom skilleveggene og under spalten 3 er det anordnet eventuelt utskiftbare oppsamlingsbeholdere (ikke vist). across the longitudinal direction of the gap, and between the partitions and under the gap 3, optionally replaceable collection containers (not shown) are arranged.
For å øke maskinens kapasitet og også dens sorteringsriktig-het er rennen, i henhold til foreliggende oppfinnelse, orientert på skrå oppover sett fra innløpsenden. Rennens vinkel c-i forhold til horisontalplanet er i henhold til oppfinnelsen fortrinnsvis 10 - 45°. Ved at rennen er orientert slik på skrå vil fisk som ligger i bunnen av rennen, d.v.s. f.eks. under annen fisk, ligge med kraftigere friksjonsinngrep mot transportbåndene i rennen og dermed føres lettere frem enn fisk som ligger høye^re i rennen, d.v.s. over annen fisk, og som derfor ikke har så sterkt friksjonsinngrep mot transportbåndene. Den høyereliggende fisk vil derfor ha en tendens til å ikke føres så raskt frem som den underliggende fisk før den selv kommer ned i bunnen av rennen og dermed kommer i kileinngrepet mellom transportbåndene. In order to increase the machine's capacity and also its sorting accuracy, the chute, according to the present invention, is oriented obliquely upwards as seen from the inlet end. According to the invention, the channel's angle c in relation to the horizontal plane is preferably 10 - 45°. Because the chute is oriented like this at an angle, fish that are at the bottom of the chute, i.e. e.g. under other fish, lie with stronger frictional engagement against the conveyor belts in the chute and are thus moved forward more easily than fish that lie higher in the chute, i.e. over other fish, and which therefore does not have such strong frictional interference with the conveyor belts. The higher-lying fish will therefore tend not to be moved forward as quickly as the underlying fish before it itself reaches the bottom of the chute and thus enters the wedge engagement between the conveyor belts.
