Et sådant apparat kendes fra det svenske patentskrift nr. 215 123. I dette apparat anvendes et med to hinanden overskærende tallerkenknive opbygget skæreværktøj, som er monteret under et par transportøren for 20 fisken dannende og over for hinanden liggende transportbånd, som giver godt greb, idet placeringen er midtsymmetrisk med fiskens arbejdsbane. Transportbåndene føres umiddelbart foran skæreværktøjets funktionsområde gennem et par symmetrisk i forhold til 25 arbejdsbanen og mod en fjederkraft tilbagetrykkelige rulletilholdere, således at transportbåndene bliver holdt mod fiskens sider. Rulletilholderne er med en stang forbundet med en under transportbåndet og skæreværktøjets tallerkenknive placeret, vippeligt 30 hængslet bugføring på en sådan måde, at med voksende afstand mellem rulletilholderne bliver også bugføringens afstand fra tallerkenknivenes snitplan større.Such an apparatus is known from Swedish Patent Specification No. 215123. In this apparatus, a cutting tool constructed with two intersecting disc knives is used which is mounted under a pair of conveyor for the fish forming and facing conveyor belts which provide good grip, the location is mid-symmetrical with the fish's work path. The conveyor belts are passed directly in front of the cutting tool's operating range through a pair of symmetrical relative to the working path and against a spring force retractable roller holders so that the conveyor belts are held against the sides of the fish. The roller holders are connected by a rod to a pivotally hinged towing plate beneath the conveyor belt and the cutting tool's cutting blades in such a way that with increasing distance between the roller holders, the distance of the towing ring from the cutting blade's cutting plane also increases.

Formålet med denne konstruktion er en automatisk til- 2 151524 pasning af bredden på den strimmel, som åbner fiskens bughule til tykkelsen af den til enhver tid bearbejdede fisk under optimering af kødudbyttet. Dette mål bliver også opnået, idet dog resultatet varierer u-5 kontrollabelt. Dette skyldes, at de fisk, der kommer til bearbejdning, i afhængighed af den for hvert parti fisk anvendte lagertid og oplagringsmåde udviser konsistens- og fangstidsbetingede konturforskelle, som specielt påvirker fiskens tykkelsesmål, som så 10 kan afvige fra de artsbetingede proportioner.The purpose of this construction is to automatically adjust the width of the strip which opens the abdominal cavity of the fish to the thickness of the processed fish at all times while optimizing the meat yield. This goal is also achieved, however, the result varies uncontrollably. This is because, depending on the storage time and storage method used for each batch of fish, the fish being processed exhibit consistency and catch-time contour differences, which specifically affect the thickness dimensions of the fish, which may then deviate from the species-related proportions.

Det er derfor formålet med denne opfindelse at tilvejebringe et apparat, der afhjælper ovennævnte ulempe ved det kendte apparat.It is therefore the object of this invention to provide an apparatus which alleviates the aforementioned disadvantage of the known apparatus.

1515

Som følge af den foreliggende opfindelses grundlæggende opgave gås der derfor ud fra fiskens højdedimension, som praktisk taget ikke påvirkes af ovennævnte forhold.Therefore, in view of the basic object of the present invention, the height dimension of the fish is assumed, which is virtually unaffected by the above conditions.

2020

Ifølge opfindelsen opnås formålet med et apparat, der er ejendommeligt ved, at der som affølingsorgan benyttes et af fisken tilbagetrængeligt rygstyringsorgan, og at overføringsorganerne består af en styre-25 stangsmekanisme med indstilleligt udvekslingsforhold, som sammenkobler rygstyringsorganet og bugstyringsorganet, så de viger tilbage modsat hinanden.According to the invention, the object of an apparatus is characterized by the use of a backrest retractable means which can be retracted by the fish and that the transferring means consist of a control rod mechanism with adjustable exchange ratio which interconnects the backrest member and the backrest member. .

De hermed opnåelige fordele er, udover overvindelse 30 af de ovenfor anførte ulemper ved det kendte apparat, at indstillingen af apparatet kun behøver at blive foretaget i forhold til de statistisk konstaterede artsrelationer. Denne indstilling sker endvidere hensigtsmæssigt ved justering af udvekslingsforholdet i 3 151524 den stangmekanisme, som udgør overføringsorganerne.The advantages thus obtained are, besides overcoming 30 of the above-mentioned disadvantages of the known apparatus, that the adjustment of the apparatus need only be made in relation to the statistically established species relations. This adjustment is furthermore conveniently made by adjusting the exchange ratio in the rod mechanism constituting the transfer means.

Opfindelsen forklares nærmere nedenfor under henvisning til tegningen, hvor 5The invention is explained in more detail below with reference to the drawing, in which:

Fig. 1 viser et skematisk, perspektivisk udsnit af apparatet med antydet transportbånd,FIG. 1 is a schematic perspective view of the apparatus with the indicated conveyor belt;

Fig. 2 apparatet skematisk set fra siden under 10 udeladelse af transportbåndet,FIG. 2 shows the apparatus diagrammatically from the side below 10 leaving the conveyor belt;

Fig. 3 et lodret snit gennem apparatet langs en linie gennem tallerkenknivenes centre under bearbejdning af en stor fisk, og 15FIG. 3 is a vertical section through the apparatus along a line through the centers of the disc knives during processing of a large fish; and

Fig. 4 et snit svarende til figur 3, men under bearbejdning af en mindre fisk.FIG. 4 is a section similar to FIG. 3, but with the processing of a smaller fish.

I en ikke vist ramme i en fiskebearbejdningsmaskine, 20 for eksempel en fileteringsmaskine, er der vist et par på sædvanlig vis omkring ligeledes ikke viste vendeskiver i vandrette planer symmetrisk roterende drevne transportbånd 1, som med de mod hinanden vendende transportbåndsflader danner arbejdsbanen for 25 fisken. Transportbåndene 1 består hensigtsmæssigt af fleksible bånd med overflader, der etablerer et godt greb ved hjælp af mange nåle. Under transportbåndene 1 findes et maskinrammefast monteret skæreværktøj 2 af to hinanden overlappende og i et vandret snitplan 30 roterende drevne og symmetrisk i forhold til fiskens arbejdsbane anbragte tallerkenknive 3. I transportretningen foran spalten mellem skæreværktøjets 2 tallerkenknive 3 og under deres snitplan er der monteret en i tværsnit konkavt udformet bugføring 4. Denne er 4 151524 lejret lodret vippeligt omkring en foretrukket ma-skinrammefast aksel 5 og hviler med sin egenvægt på et anslag 6, der fikserer føringens 4 størst mulige afstand mellem dens føringsflade og tallerkenknivenes 5 3 snitplan. Bugføringen 4 er udformet med en side værts udragende, opadrettet styrestang 7. Over fiskens arbejdsbane og omtrent endende over tallerkenknivenen 3 spalte findes en ligeledes slæbende lejret, i lodret retning vippelig rygføring 8 maskinram-10 mefast monteret, som hviler på et med den mindst mulige afstand til bugføringen 4 fikserende anslag 10. Rygføringen 8 bærer en støttestang 11, der kan indstilles i en vinkelstilling i forhold til rygføringen 8, og som har monteret en støtterulle 12 på sin frie 15 ende. Støtterullen 12 støttes af styrestangen 7.In a frame not shown in a fish processing machine, 20 for example a filleting machine, a pair of conventionally shown turntables in horizontal planes are also shown symmetrically rotating driven conveyor belt 1, which with the opposite conveyor belt surfaces forms the working path for the fish. Conveniently, the conveyor belts 1 consist of flexible belts with surfaces which establish a good grip by means of many needles. Under the conveyor belts 1 are a machine frame fixedly mounted cutting tool 2 of two overlapping and rotating driven and symmetrical plate knives 3 rotating in a horizontal plane 30 and symmetrically in relation to the working path of the fish. In the transport direction in front of the gap between the cutting tools 2 of the cutting tool 2 and below them a cutting plane is mounted. cross section concavely designed towing 4. This is mounted vertically pivotally around a preferred machine frame-fixed shaft 5 and rests with its own weight on a stop 6, which fixes the greatest possible distance of the guide 4 between its guide surface and the cutting plane of the disc knives 5 3. The towing guide 4 is formed with a side host protruding, upward guide rod 7. Above the fish's working path and approximately ending above the plate knife 3 there is also an equally tugged, vertically tilted back guide 8 machine frame 10 firmly mounted which rests on one with the least possible distance from the abdominal guide 4 fixing stop 10. The back guide 8 carries a support rod 11 which can be adjusted in an angular position with respect to the back guide 8 and which has a support roller 12 mounted on its free end. The support roll 12 is supported by the guide rod 7.

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

En mellem transportbåndende 1 i svømmestilling frem-20 ført, sædvanligvis afhovedet fisk når først frem til bugføringen 4 med sin bug, som over rygføringens 8 støttestang 11 bliver holdt fri af anslaget 6 ved hjælp af kraften fra den på støttestangen 11 virkende fjeder 9. Under transportens videre forløb løber fi-25 sken med sin ryg ind under rygføringen 8, som herved indstiller sig efter fiskens ryghøjde. Ved rygføringens 8 tilbagepresning svinger også støttestangen 11 ud, således at styrearmen 7 på hertil svarende måde følger med virkningen, så bugføringens 4 afstand i 30 forhold til tallerkenknivenes 3 snitplan indstiller sig på et større mål. Løber fiskens haledel mellem bug- og rygføringen 4, henholdsvis 8, så indstiller der sig på grund af det mindre højdemål i dette område af fisken en mindre afstand mellem bugføringen 4 5 151524 og tallerkenknivenes 3 snitplan.An intermediate conveyor belt 1 conveyed in the swimming position, usually head fish, first reaches the guide guide 4 with its belly which is held free of the impact 6 by the support 11 of the back guide 8 by the force of the spring 9 acting on the support rod 11. the further course of transport, the fi sh runs with its back under the back guide 8, which thereby adjusts to the fish’s back height. At the backpressure of the back guide 8, the support rod 11 also swings out, so that the guide arm 7 corresponds accordingly with the effect, so that the distance of the guide guide 4 in relation to the cut plane of the disc knives 3 adjusts to a larger target. If the tail portion of the fish runs between the abdominal and back guide 4 and 8, respectively, due to the smaller height in this area of the fish, a smaller distance between the guide guide 4 5 151524 and the cutter plane of the disc knives 3 is adjusted.

Der opnås derved en automatisk tilpasning af bugstrimlens bredde ikke blot i forhold til den til en-5 hver tid forekommende fiskestørrelse, men også til det under udskæringen til enhver tid i snitområdet forekommende kropstværsnit. Endvidere kan man ved tilsvarende indstilling af det anslag 10, som fastlægger den laveste stilling for rygføringen 8, opnå 10 det, at snittet løber ud kort bag bughulens ende, og at haleområdet altså forbliver upåvirket.Thereby an automatic adjustment of the width of the belly strip is achieved not only in relation to the fish size occurring at any one time, but also to the body cross-section occurring at any time during the cut. Furthermore, by corresponding adjustment of the stop 10, which determines the lowest position for the back guide 8, 10 it can be achieved that the incision runs out shortly behind the end of the abdomen and thus the tail area remains unaffected.
