Opfindelsen angår et apparat til automatisk forsyning af 5 fiskebearbejdningsmaskiner med fisk, omfattende henholdsvis i det mindste et rytmeorgan til rytmisk udtagelse af fisk, der ligger klar med hovedet fremad og i sidestilling i et tilførselsorgans opstuvningskammer, med mindst en roterende drevet medbringertransportør i form af et rytmehjul med 10 mindst en medbringer, der griber gennem oplægningsfladen i opstuvningskammerets område, et bug-ryg-retteorgan til opretning af fisken i ensartet bug-ryg-stilling bestående af en drevet, omkring en i hovedsagen lodret akse roterende tandvalse og et over for dennes kappeflade liggende 15 føringselement samt et mellem rytmeorganet og bug-ryg-retteorganet anbragt transportorgan.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to an apparatus for automatically supplying five fish processing machines with fish, comprising at least one rhythmic means for the rhythmically taking out of the fish, which is clear with the head forward and juxtaposed in the stowage chamber of a supply means, with at least one rotary driven carrier conveyor in the form of a rhythm wheel having at least one carrier gripping through the support surface in the area of the stowage chamber, a bug-back straightener for aligning the fish in a uniform bug-back position consisting of a driven, about a substantially vertical axis rotating tooth roller casing surface 15, and a transport member arranged between the rhythm member and the bug-back straightener.

Et sådant apparat kendes fra det tyske patentskrift nr. 33 09 602. Dets væsentlige kendetegn er, at transportstræknin-20 gen omfatter en mellem bug-ryg-retteorganet og rytmeorganet sig strækkende, drevet transportbånd, der er bestykket med nåle, hvis delingsafstand er større end længden af den største fisk, der skal håndteres.Such an apparatus is known from German patent specification 33 09 602. Its essential characteristic is that the conveying line comprises a conveyor belt extending between the abdominal back rectifier and the rhythm member, which is equipped with needles whose spacing is greater than the length of the largest fish to be handled.

25 Fra den i praksis anvendte teknik kendes også et apparat med et rytmehjul, der i sin periferi er forsynet med nåle, der griber gennem oplagsfladen i opstuvningskammeret, og som er udformet som tandremskive til optagelse af to tandremme, der mellem sig afgrænser en spalte gennem hvilken 30 nålene kan række, og som danner en tilførselsstrækning til bug-ryg-rettevalsen.In the practice of the art, there is also known an apparatus with a rhythm wheel, which at its periphery is provided with needles which grip through the storage surface of the stowage chamber, and which is designed as a toothed pulley for receiving two toothed straps defining a gap between them. which 30 needles can row and which form a supply line to the bug-back straight roller.

Disse apparaters funktionelle sikkerhed er ikke tilfredsstillende. Således forekommer der en tilbøjelighed til til-35 stopning, der gør økonomien tvivlsom, såfremt kvaliteten af den fisk, der skal forarbejdes, ikke er helt ulastelig.The functional safety of these devices is not satisfactory. Thus, there is a tendency for padding that makes the economy questionable if the quality of the fish to be processed is not entirely impeccable.

DK 167203 B1 2 Sådanne forstyrrelser frembringes især af beskadigede fisk, der allerede giver vanskeligheder ved hoved-hale-opretnin-gen og uundgåeligt medfører, at der iblandt også i rytmeorganets område forefindes fisk, der er orienteret med halen 5 fremad. I så tilfælde kan det let komme til blokeringer på den måde, at finnerne på sådanne fejlorienterede fisk spredes ud og trænger ned i spalten, som i det mindste findes i det område, hvor nålene dykker bort. Særligt kritisk ved den først omtalte teknik har området for det nålebestykkede 10 transportbånds vending i udløbsområdet vist sig at være. Thi dette vendested skal nødvendigvis findes foran bug-ryg-rettevalsen for det første af funktionelle årsager for at bringe opretningskræfterne i bug-ryg-retteorganet til at virke på den nødvendige måde, det vil sige uhindret, og for 15 det andet af konstruktive årsager for ikke at lade transportbåndets nåle kollidere med bug-ryg-rettevalsen. Den derved uundgåeligt opstående spalte indebærer den ovennævnte risiko.Such disturbances are mainly caused by damaged fish, which already cause difficulties in the head-tail erection and inevitably result in fish even oriented in the area of the rhythm organ with the tail 5 forward. In that case, it can easily be blocked in that the fins of such fault-oriented fish spread out and penetrate into the gap, which is at least found in the area where the needles dive. Particularly critical in the first-mentioned technique, the area of the turning of the needle-fastened conveyor belt 10 in the outlet area has been found to be. For this turning point must necessarily be located in front of the bug-back straight roller, firstly for functional reasons, in order to cause the upright-back straightening forces to act in the necessary manner, that is, unimpeded, and secondly for constructive reasons for not to allow the conveyor belt needles to collide with the bug-back straightening roller. The gap that inevitably arises involves the above risk.

20 Det er formålet med opfindelsen at frembringe en konstruktiv forbedring af dette område i det kendte forsyningsapparat for at sikre, at også sådanne fejlorienterede fisk kan passere gennem apparatet, det vil sige, at de ikke frembringer nogen blokering.The object of the invention is to provide a constructive improvement of this area in the known supply apparatus to ensure that such faulty fish can also pass through the apparatus, that is, they do not cause any obstruction.

Dette formål opnås ifølge opfindelsen med et apparat af den i indledningen anførte art, såfremt det er ejendommeligt ved, at transportorganet udgøres af overdelen af en som oplag for fisken tjenende, endeløs tandrem, der vendes dels 30 omkring det som tandremskive udformede rytmehjul og dels i området under tandvalsens nedre flanke, og at medbringeren eller medbringerne hver gang dykker igennem en tilsvarende dimensioneret gennemskæring i tandremmen.This object is achieved according to the invention with an apparatus of the kind mentioned in the introduction, if it is peculiar in that the conveying means is constituted by the upper part of an endless toothed belt serving as a storage for the fish, which is turned partly around the rhythm wheel formed as a toothed pulley and partly in the area under the lower flank of the tooth roller and that each time the carrier (s) dives through a correspondingly dimensioned cut in the tooth belt.

35 Den forbedring af funktionssikkerheden, som man opnår med et apparat af denne type skyldes især, at hele fiskeførin- DK 167203 B1 3 gens område fra rytmeorganet til bug-ryg-retteorganet er holdt fri for enhver slids eller spalte, hvori især finner eller udhængende indvolde kan fanges. Desuden er det muligt på denne måde at bringe transportorganernes angreb til 5 virkning også i bug-ryg-rettevalsens område og endda hen over denne, og at forlægge transportorganets bortdykningsspalte til et ikke kritisk område.35 The improvement in functional safety achieved with an apparatus of this type is mainly due to the fact that the entire area of the fishing guide from the rhythm to the bug-back means is kept free of any slit or slit, in particular fins or pendants. viscera can be caught. In addition, it is possible in this way to bring about the attack of the transport means to the effect also in the area of the bug-back straight roller and even over it, and to position the diverter gap of the transport member to a non-critical area.

En fordelagtig udførelsesform for opfindelsen er ejendomme-10 lig ved, at rytmehjulets omkreds henholdsvis tandantal og delingen for gennemskæringer i tandremmen henholdsvis det til delingen svarende tandtal står i et indbyrdes forhold, som er et helt tal.An advantageous embodiment of the invention is characterized in that the circumference of the rhythm wheel, respectively, of tooth number and the division for intersections in the tooth belt and the corresponding tooth number, respectively, are in a ratio which is an integer.

15 Dermed har man for en tandrem med et tandantal på 1,5 gange rytmehjulets tandtal en deling for gennemskæringerne svarende til rytmehjulets halve tandtal, ved tandremmens dobbelte tandtal en deling svarende til rytmehjulets total-tandtal.15 Thus, for a toothed belt with a tooth count of 1.5 times the rhythm of the rhythm wheel, there is a division for the intersections corresponding to the half tooth of the rhythm wheel, at the double tooth count of the tooth belt a division corresponding to the total tooth number of the rhythm wheel.

Nedenfor beskrives opfindelsen nærmere under henvisning til et i tegningen illustreret eksempel på en udførelsesform.The invention is further described below with reference to an example of an embodiment illustrated in the drawing.

Den eneste figur viser en perspektivisk skitse af apparatet i simplificeret illustration.The only figure shows a perspective sketch of the apparatus in simplified illustration.

25 I et ikke vist chassis til et fyldeapparat for fisk er der monteret et ligeledes ikke vist hoved-hale-retteorgan af kendt konstruktion, et rytmeorgan 1 og et efterkoblet bug-ryg-retteorgan 2. Rytmeorganet 1 omfatter et på passende 30 måde i pilretningen drevet rytmehjul 3, som er udformet som tandremskive og i sin periferi er forsynet med en medbringer 4. Medbringeren 4 er udformet kamagtigt og har en række savtænder 5 med i bevægelsesretningen fremadvendende stejlside. Rytmehjulet 3 omslynges af en endeløs tandrem 6, 35 hvis overdel 7, som er ført vandret til skråt nedad og danner bundfladen 8 i en føringsrende 9, til hvilken den DK 167203 B1 4 maskine, som skal forsynes, er tilsluttet. Tilbageføringen eller vendingen af tandremmen 6 sker ved hjælp af en venderulle 10 i det endeområde for føringsrenden 9, som vender mod den maskine, som skal fyldes, idet venderullen 10 fører 5 tandremmen 6 under føringsrenden 9 over en spænderulle 11 tilbage mod rytmehjulet 3. I den her valgte udførelsesform har tandremmen 6 i forhold til rytmehjulet 3 det dobbelte tandantal, således at den med to gennemskæringer 12 er udformet med en deling, som svarer til rytmehjulets 3 10 tandtal, så medbringeren 4 kan række igennem disse under rytmehjulets 3 rotation.In a chassis for a fish filling apparatus there is mounted a similarly illustrated main tail straightener of known construction, a rhythm member 1 and a post-coupled bug-back straightener 2. The rhythm member 1 comprises a suitable way in the arrow direction. driven rhythm wheel 3, which is formed as a toothed pulley and is provided at its periphery with a carrier 4. The carrier 4 is cam-shaped and has a series of saw teeth 5 with a steeply facing steep side. The rhythm wheel 3 is enclosed by an endless toothed belt 6, 35, the upper part 7 of which is moved horizontally downwards and forms the bottom surface 8 of a guide ring 9, to which the machine to be supplied is connected. The reversing or turning of the toothed belt 6 takes place by means of a turning roller 10 in the end region of the guide gutter 9 facing the machine to be filled, the turning roller 10 guiding the toothed belt 6 below the guide gutter 9 over a tensioning roller 11 towards the rhythm wheel 3. In the embodiment chosen here, the toothed belt 6 has a double tooth count relative to the rhythm wheel 3, so that with two cuts 12 it is formed with a pitch corresponding to the tooth number of the rhythm wheel 3, so that the driver 4 can pass through them during the rotation of the rhythm wheel 3.

Bug-ryg-retteorganet findes i det endeområde af føringsrenden 9, der vender mod den maskine, der skal forsynes. Det 15 omfatter en tandvalse 13, der roterer omkring en i forhold til føringsrendens 9 bundflade 8 sideværts forsat, lodret akse 14. Tandvalsen 13 drives på den måde, at dens i føringsrenden 9 indragende og af hensyn til forbedret gri-beevne med tænder udformede kappeflade 15 bevæges i tand-20 remmens 6 bevægelsesretning. Tandvalsen 13 er placeret med sin mod tandremmen 6 vendende flanke 16 i lille afstand fra denne, og den er i overgangsområdet mellem flanken 16 og kappefladen 15 udformet med en fas 17. Kappefladen 15 ligger over for et omkring en lodret, ved siden af føringsren-25 den 9 og i tandremmens 6 bevægelsesretning foran tandvalsen 13 anbragt svingakse 18 svingbart føringselement 19. Dette danner med tandvalsens 13 kappeflade 15 en for fisken i hovedsagen parallel passage, som mod kraften fra en ikke vist fjeder kan forstørres ved fortrængning. Føringselemen-30 tet 19 fortsætter ud over tandvalsen 13 i en ved vridning skrånende del 20, der ligger over for en tilsvarende udformet føringsdel 21.The bug-back straightener is located in the end region of the guide gutter 9 facing the machine to be provided. It 15 comprises a tooth roller 13 which rotates about a laterally vertical vertical axis 14 relative to the bottom surface 8 of the guide gutter 9. The tooth roller 13 is driven in such a way that its cutting surface is formed in the guide gutter 9 and for improved grip ability with teeth. 15 is moved in the direction of movement of the toothed belt 6. The tooth roller 13 is positioned with its flank 16 facing the tooth belt 6 at a small distance from it, and in the transition region between the flank 16 and the casing surface 15 is formed with a shaft 17. The cutting surface 15 is opposite one about a vertical, adjacent to the guide ring. 25 and 9, in the direction of movement of the toothed belt 6, in front of the tooth roll 13, pivot axis 18 is pivotable guide element 19. This forms with the cutting surface 15 of the tooth roll 13 a parallel passage for the fish, which can be enlarged against the force of a spring not shown by displacement. The guide member 19 continues beyond the tooth roll 13 in a pivoting portion 20 inclined by rotation, which faces a correspondingly formed guide member 21.

Apparatets funktionsmåde er følgende:The operation of the device is as follows:

Kommende fra et egnet hoved-hale-orienteringsorgan via en 35 DK 167203 B1 5 på sædvanlig måde vibrerende drevet tilførselsrende 22 løber fisken i sidestilling med sit hoved ind under en ikke vist fangklap og opbremses af denne, i reglen til hvile. Medbringeren 4 befinder sig herunder i sit omløb og dykker 5 slutteligt gennem en bundspalte ind i tilførselsrenden 22 i området under fangklappen, som fastholder fisken. Herunder har medbringeren 4 i tandremmens 6 opløbssted på rytmehjulet 3 truffet gennemskæringen 12 i tandremmen 6, hvis stilling er justeret til dertil svarende afstemning med ryt-10 mehjulets 3 periferi og takket være den formfaste kobling mellem dette og tandremmen 6 samt afstemningen mellem dennes længde og rytmehjulets 3 omkreds hver gang gentages synkront.Coming from a suitable head-tail orientation means via a conventional vibrating driven feed ring 22, the fish runs in juxtaposition with its head under a catch not shown and is braked by it, as a rule, to rest. The carrier 4 is located below in its circulation and finally dives 5 through a bottom slit into the supply channel 22 in the area below the catch flap which holds the fish. Below, the driver 4 in the running belt of the timing belt 6 on the rhythm wheel 3 has intersected 12 in the timing belt 6, the position of which is adjusted for corresponding alignment with the periphery of the rhythm wheel 3 and thanks to the form-fitting coupling between it and the timing belt 6 as well as the adjustment between its length and the circumference of the rhythm wheel 3 is repeated each time synchronously.

15 Opdukningen af medbringeren 4 bevirker i hovedsagen med dens første tand en medbringen af fisken ved greb bag gæl lelågets bageste kant, hvilket forløb som følge af fang-klappens indstillingsposition afvikles hurtigt med træfsikkerhed. Den således accelererede fisk når dermed frem på 20 tandremmens 6 overdel 7 og bliver af denne båret videre, idet medbringeren 4 som følge af sin binding til rytmehjulet 3 og tandremmens 6 tangentiale afløb fra dette umiddelbart efter sin opdukken straks efter igen dykker bort. Således tilføres fisken til bug-ryg-retteorganet 2 og træn-25 ger der ind i passagen mellem føringselementet 19 og tandvalsens 13 kappeflade 15 og rettes der op af tandvalsen 13, som samtidigt overtager dens transportering. Det sker ved, at fisken på grund af sit legemes dråbeformede tværsnit med dets kamlignende bugkontur alt efter stilling til venstre 30 eller til højre løber ind i fasen 17 eller i en mellem føringselementet 19 og tandremmen 6 værende spalte. Det fjedertryk, som udøves på føringselementet 19, bevirker herunder, at fisken under fortrængningen af føringselementet 19 altid rettes op i svømmestilling. Fra denne stilling 35 bliver den så ved hjælp af føringselementets 19 vredne del 20 drejet ind i en bestemt sidestilling.The emergence of the carrier 4 substantially with its first tooth causes the fish to be brought by grip behind the trailing edge of the gill lid, which due to the position of the catch flap is quickly wound with accuracy. The fish thus accelerated reaches the upper part 7 of the toothed belt 6 and is carried by it, the diver 4, due to its attachment to the rhythm wheel 3 and the tangential drain of the toothed belt 6 immediately after its appearance, immediately dives again. Thus, the fish is fed to the bug-back straightener 2 and enters 25 into the passage between the guide member 19 and the cutting surface 15 of the tooth roll 13 and is raised by the tooth roll 13, which simultaneously takes over its transport. This occurs because the fish, due to the droplet cross-section of its body with its crest-like contour, depending on the position on the left 30 or on the right, runs into the phase 17 or into a gap between the guide element 19 and the toothed belt 6. The spring pressure exerted on the guide member 19 causes, among other things, that the fish during the displacement of the guide member 19 always aligns in the swimming position. From this position 35 it is then rotated into a certain lateral position by means of the twisted part 20 of the guide element 19.

Takket være tandvalsens 13 underføring gennem tandremmen 6 bliver fisken transporteret sikkert i dette forløb, idet det på fisken indvirkende opretningsmoment samtidigt frit 5 kan udfoldes. Ligeledes sikres det ved dette apparat, at bifangst, fiskedele, beskadigede fisk og andet samt fejlorienterede fisk, det vil sige fisk, som ankommer med halen forrest, gennemløber bug-ryg-retteorganets kritiske område uden blokering. Dette begunstiges også afgørende derved, at 10 tandremmens 6 bortdykningssted befinder sig bag tandvalsen 13.Thanks to the passage of the tooth roll 13 through the toothed belt 6, the fish is safely transported in this process, while at the same time the uprighting moment acting on the fish can be freely unfolded. Also, this apparatus ensures that by-catch, fish parts, damaged fish and other and misaligned fish, that is, fish arriving with the tail at the front, pass through the critical area of the bug-spine without blocking. This is also decisively favored in that the dive site of the toothed belt 6 is behind the tooth roll 13.
