i 5 Opfindelsen angår et apparat til afskinding af fiskefileter og af den i krav l's indledning angivne art.The invention relates to an apparatus for cutting fish fillets and of the nature specified in the preamble of claim 1.

Sådanne apparater til afskinding er udstyret med af-skindingsvalser, der på deres omkreds er forsynet med 10 en regelmæssig fortanding, ved hvilke de i om løbsfladen liggende endesider af tænderne er meget smalle og hullerne mellem tænderne forholdsvis store og dybe. For at forbedre indløbet af skindet af den fortil løbende fiskefilet-ende under skæret af af-15 skindingskniven kendes fra tysk offentliggørelses skrift 25 23 752 et sådant apparat, hvis afskin-dingskniv ved sit skær har en fra omkredsen af af-skindingsvalsen og mod omløbsretningen af den rettet flade.Such apparatus for abrasion is provided with abrasive rollers which are provided at their perimeter with a regular tooth, in which the end faces of the teeth lying about the running surface are very narrow and the gaps between the teeth relatively large and deep. In order to improve the inlet of the skin of the predetermined fish fillet end under the cutting of the skinning knife, from German publication 25 23 752, such an apparatus is known, the shearing knife having at its cutting edge one from the circumference of the skinning roll and towards the direction of rotation. of the directed surface.

20 I dansk fremlæggelsesskrift nr. 129966 er der anvist en maskine til flåning af fiskefileter, der er udstyret med en flåningsvalse, som til brug ved flåning af fisk med tyndt eller glat skind har langsgående 25 noter med ringe dybde, samt en trykvalse, hvorpå der ligeledes er langsgående noter.20 in Danish Patent Specification No. 129966, a machine for skinning fish fillets has been provided, which is equipped with a skinning roller which, for use in skinning fish with thin or smooth skins, has longitudinal 25 grooves of low depth, and a pressure roller on which likewise are longitudinal notes.

I norsk fremlæggelsesskrift nr. 140700 er der anvist en maskine til afskinding af fiskefileter med en af-30 skindingsvalse, på hvis overflade der er anordnet fordybninger til modtagelse af fiskefileten. Fordybningerne ligger tæt ved hinanden, og der er ingen riflet eller rouleteret overflade på afskindingsval-sen til sikring af en fast kontakt mellem fiskefile- 2Norwegian Patent Specification No. 140700 discloses a machine for scooping fish fillets with a scrubbing roll, on whose surface there are recesses for receiving the fish fillet. The recesses are close to each other, and there is no grooved or rotated surface on the rolled roller to ensure a firm contact between the fish files.

\ \ \ \ \- ten og afskindingsvalsen.\ \ \ \ \ - and the rolling drum.

Afskindingsmaskinen ifølge den foreliggende opfindelse er udstyret med en af skindingsvalse, hvor de 5 langsgående noter er anbragt i en afstand fra hinanden, der er større end deres bredde.The skinning machine according to the present invention is equipped with one of the skinning rollers, wherein the 5 longitudinal grooves are spaced apart from each other which is greater than their width.

I den foreliggende opfindelse er der tale om en konstruktion, hvor fordelene fra de to ovennævnte frem-10 læggelsesskrifter er udnyttet, med det formål at anvise en afskindingsmaskine, hvor fiskefileten sikres et indløb under afskindingskniven, samtidig med at afskindingen bliver økonomisk rationel, dvs. at der ikke bliver skåret fiskekød væk sammen med fiskeskin-15 det.The present invention is a construction in which the advantages of the two abovementioned specifications are utilized, for the purpose of providing a rinsing machine in which the fish fillet is secured an inlet under the razor blade, while at the same time roving becomes economically rational, ie. that fish meat is not cut away with fish skin-15.

Den tilsigtede virkning ifølge den foreliggende opfindelse kan forklares ud fra følgende betragtninger: 20 Det enkleste konstruktionsprincip i en afskindings maskine består i anvendelse af en afskindingsvalse, hvorpå der er en riflet omløbsflade, på hvilken fileten med sin skindside bliver tilført mod skæret på en i ringe afstand fastgjort kniv, ved hvilken der ne-25 denunder er en påtrykningsflade, som sammen med afskindingsvalsen danner en snæver spalte.The intended effect of the present invention can be explained from the following considerations: 20 The simplest design principle of a skinning machine consists of the use of a skinning roll, on which there is a ribbed orifice surface, on which the fillet with its skin side is applied to the cut on a ring. spaced fixed knife, at which there is a pressing surface below, which together with the shearing roller forms a narrow gap.

Ulempen ved denne type afskindingsmaskine er, at når skindet på fileten rammer afskindingsknivens skær, 30 rammer fileten ikke altid spalten mellem påtrykningsfladen og omløbsfladen på afskindingsvalsen, med det resultat, at fileten glider væk uafskindet over skæret. For de fisk, hvor fileten ikke glider væk u-afskindet, er metoden optimal.The disadvantage of this type of sewing machine is that when the skin of the fillet hits the cutter's cutter, the fillet does not always hit the gap between the pressing surface and the bypass surface of the cutter roller, with the result that the fillet slides away unscathed over the cutter. For those fish where the fillet does not slip away un-skinned, the method is optimal.

For at afhjælpe manglerne ved denne type afskindings-maskiner har man forsøgt at anordne fordybninger på forskellig måde på omløbsfladen af afskindingsvalsen 5 for at give filetsnippen mulighed for, ved at lægge den ind i disse fordybninger, at opnå en sikkerhed for, at skindet bliver ført ind i spalten mellem påtrykningsfladen og omløbsfladen på afskindingsvalsen.In order to alleviate the shortcomings of this type of scouring machines, attempts have been made to arrange recesses in different ways on the orbital surface of the scissors roll 5 to allow the fillet snippet, by inserting it into these recesses, to obtain a guarantee that the skin is guided into the gap between the pressing surface and the bypass surface of the sheathing roller.

10 Med en valse som den omtalt i dansk fremlæggelsesskrift 129966 og norsk fremlæggelsesskrift nr. 140700 lykkedes dette ganske vist, dog viser det sig, at der er en forringelse af udbyttet af værdifuldt fiskekød, fordi der over forskydningerne er frit spændt skind, 15 som under afskindingsprocessen mangler støttende underlag.10 With a roller such as the one mentioned in Danish Patent Specification 129966 and Norwegian Patent Specification No. 140700, this succeeded, however, it turns out that there is a decrease in the yield of valuable fish meat, because over the displacements are freely tensioned skin, 15 as under the abrasion process lacks supportive backing.

Få grundlag af disse betragtninger kan det fastslås, at snittesikkerheden og udbyttet ikke samtidigt kan 20 optimeres.On the basis of these considerations, it can be concluded that the average safety and yield cannot simultaneously be optimized.

Med afskindingsmaskinen ifølge den foreliggende opfindelse er det ikke desto mindre muligt på den ene side at holde fordybningerne tilstrækkelig store og 25 på den anden side at sikre en tilstrækkelig understøtning af skindet på omløbsfladen, det vil sig på felter, som ligger mellem de enkelte fordybninger på omløbsfladen.Nevertheless, with the sizing machine according to the present invention, it is possible on the one hand to keep the indentations sufficiently large and on the other hand to ensure sufficient support of the skin on the orbital surface, that is to say in fields located between the individual indentations of circumferential surface.

30 I forhold til de forskellige udførelsesformer ved den kendte teknik ligger fordelen ved opfindelsen deri, at spildet, som er stort fra den del af fileten, der ligger i det område, som under afskindingen kommer til at ligge over fordybningen, bliver begrænset mest 4In relation to the various embodiments of the prior art, the advantage of the invention lies in the fact that the waste, which is large from the part of the fillet which lies in the area which will lie above the recess during the shredding, is most limited.

I en udførelsesform ifølge opfindelsen er noterne anbragt i form af skruelinier på omløbsfladen. Derved 5 er der opnået mulighed for ved smalle noter at forøge indgrebslængden for skindet.In one embodiment of the invention, the grooves are arranged in the form of screw lines on the orbital surface. In this way 5, it is possible to increase the length of engagement of the skin by narrow notes.

I en yderligere udførelsesform ifølge opfindelsen er noterne anbragt i form af hinanden krydsende skrueli-10 nier. Derved er der opnået mulighed for at forøge antallet af indgrsbssteder for skindet.In a further embodiment of the invention, the grooves are arranged in the form of intersecting helices. Thereby, it is possible to increase the number of leather entry points.

I en yderligere udførelsesform ifølge opfindelsen er noterne anbragt i pileform på omløbsfladen. Derved er 15 der opnået den mulighed at forbedre det jævne og sikre anlæg af huden ved stræk.In a further embodiment of the invention, the grooves are arranged in arrow shape on the orbital surface. This gives 15 the opportunity to improve the smooth and safe application of the skin on stretch.

Ifølge en yderligere udførelsesform ifølge opfindelsen har den af noter i felter opdelte overflade på 20 afskindingsvalsen en mekanisk, kemisk eller elektro-lytisk frembragt opruning. Derved kan der opnås en til medbringningen af skindet tilstrækkelig friktionskoefficient, uden fare for reduktion af udbyttet af fiskekød.According to a further embodiment of the invention, the groove-divided surface of grooves on the abrasive roller has a mechanical, chemical or electrolytic origin. In this way, a sufficient coefficient of friction can be obtained for the skin, without the risk of reducing the yield of fish meat.

25 I en yderligere udførelsesform ifølge opfindelsen er felterne mellem noterne forsynet med en fortanding med lille dybde. Derved kan der opnås en yderligere beroligelse af den foranløbende ende af en fiskefilet 30 før dens indløb i afskindingskniven.In a further embodiment of the invention, the fields between the grooves are provided with a low depth tooth. Thereby further calming of the leading end of a fish fillet 30 can be achieved before its entry into the cutter knife.

This facilitates the insertion of the fillet's tail slit into one of the recesses placed between the fields.

10 I en yderligere udførelsesform ifølge opfindelsen er ledefladen anbragt svingeligt om en med aksen af afskindingsvalsen parallel akse og udfører i fremføringsretningen af fiskefileterne en oscillerende bevægelse med lille slaglængde. Derved er sikret mulig-15 hed for tvangsmæssig indføring af den foranløbende halesnip af stive eller dødstive fileter i en af de mellem felterne anbragte fordybninger og adskillelse af fibrene mellem skind og filet ved enden af afskin-dingsprocessen.In a further embodiment of the invention, the guide surface is pivotally positioned about an axis parallel to the axis of the scoop roll and performs in the direction of advance of the fish fillets an oscillating movement of small stroke. This provides for the possibility of forcibly inserting the leading tail snap of rigid or dead rigid fillets into one of the recesses between the fields and separating the fibers between skins and fillets at the end of the cutting process.

Mellemrummet mellem skæret 41 henholdsvis påtrykningsfladen 42 og omløbsfladen 21 af afskindingsvalsen 2 er nogle tiende-del-millimeter. Med fordel er afskindigskniven 4 således anbragt eller indrettet, at den mod kraftigt 10 fjedertryk kan undvige bort fra omkredsen af afskindingsvalsen 2. Over skæret 41 af afskindingskniven 4 er der anbragt en i ét eller flere stykker udført påtrykningsvalse 5, der er drevet i retning af omkredspilen og er anbragt undvigeligt mod fjederkraft, 15 eller der er anbragt en om en med rotationsaksen af afskindingsvalsen parallel akse 71 svingelig ledeflade 7. Den cylindriske omløbsflade 21 af afskindingsvalsen 2 er ved langs kappelinierne forløbende fordybninger 25 delt i felter 22, hvilke har opruninger 20 af lille radial dybdeudstrækning. Der er antydet en krydsrifling 23 henholdsvis en fin fortanding 24, der tjener til klemmende medtagning af skindet langs påtrykningsfladen 42 af afskindingskniven 4. De viste fordybninger 25 har form af uregelmæssige eller uli-25 gesidede trapezer, hvis dybde 27 kun er en brøkdel af deres bredde 26 og hvis efterløbende flanker er skrå mod omløbsretningen af afskindingsvalsen. I et eksempel var bredden af noten ca. 5 mm og dens dybde ca.β than the velocity of the feed belt 1. Above the upper half of the roll-on roller 2, a cut-off knife 4 is arranged rigidly and lies with its pressing surface 42 equidistant to the orbital surface 21 of the roll-on roll 2. The space between the cutting 41 and the pressing surface 42, respectively, and the turning surface 21 of the shear roll 2 are some tenths of a millimeter. Advantageously, the cutter knife 4 is positioned or arranged so that it can escape from the circumference of the cutter roller 2 against strong spring pressure away from the circumference of the cutter roller 2. Over the cutter 41 of the cutter knife 4, a pressing roller 5 made in one or more pieces is driven in the direction of the circumferential arrow and is avoidably disposed against spring force 15 or a rotatable guiding surface 7 which is pivotable with the axis of rotation of the shear roll 71. The cylindrical bypass surface 21 of the shear roll 2 is divided by grooves 25 extending along the shaft lines 25 of small radial depth extension. Crossings 23 and a fine tooth 24, respectively, are used which indicate clamping of the skin along the pressing surface 42 of the cutter knife 4. The recesses 25 shown are in the form of irregular or non-sided trapezoid, whose depth 27 is only a fraction of their width 26 and the trailing edges of which are inclined towards the direction of rotation of the roll bar.

Virkemåden af apparatet er følgende:The operation of the apparatus is as follows:

En med skindsiden på tilførselsbåndet 1 lagt fiskefilet bliver af dette med haleenden forrest ført til 5 ombøjningsstedet over ombøjningsvalsen 11, hvor overføringsvalsen 3 leder halesnippen over på omløbsfladen 21 af afskindingsvalsen 2. Den fine fortanding 31 på overføringsvalsn 3 er derved i stand til at løfte filet-enden fra tilførselsbåndet 1, men forhindrer 10 påvirkning af filet-enden til flagrebevægelser i lodret retning. Den hurtigere end den tilførte haleende af fiskefileten omløbende afskindingsvalse 2 glider med sine felter 22 og fordybninger 25 igennem under skindsiden af fiskefileten, indtil dennes foranløben-15 de ende har nået skæret 41 af afskindingskniven 4. På grund af den kun med lille radial højdeudstrækning udformede opruning af felterne 22 på afskindingsvalsen 2 hviler skindet derved jævnt og pålideligt på omløbsfladen 21. Som følge deraf falder skindet af 20 haleenden derved i løbet af kort tid ind i den pågæl dende under den passerende fordybning 25. Når ved ankomsten af skæret 41 af afskindingskniven 4 haleenden af fiskefileten med sit skind igen trænger ind i en fordybning 25, sker der øjeblikkeligt ved hjælp af 25 den under skæret 41 liggende påtrykningsflade 42 en klemning af skindet, der for skæret 41 muliggør en indtrængning mellem skindet og sølvlaget af fiskefileten og dermed en adskillelse af fiskekødet fra skindet. Denne proces sker med stor sikkerhed, når 30 fiskefileten i udbredt tilstand tilføres fra tilførselsbåndet 1. Den over skæret 41 beliggende påtrykningsvalse 5 kommer især til virkning, når der foreligger uregelmæssigheder i stillingen af fiskefileten. En i stedet derfor anbragt ledeflade 7 viser sig 8A fish fillet placed with the skin side of the feed belt 1 is guided therewith with the tail end to the bending point over the bending roller 11, the transfer roller 3 leading the tail snip over on the bypass surface 21 of the binning roller 2. The fine tooth 31 on the transfer roller 3 is thus capable of lifting. end from the feed belt 1, but prevents 10 impact of the fillet end to flutter movements in the vertical direction. The fastening tail 2 of the fish fillet, which is rotating faster than the applied tail end, slides with its fields 22 and recesses 25 under the skin side of the fish fillet until its leading end 15 has reached the cut 41 of the cutter knife 4. Due to the small radial height extension formed thereby, the skin of 20 tail end thereby falls within the respective one during the passing recess 25. When on the arrival of the cutting 41 of the cutter knife, the skin of the tail end 22 is evenly and reliably rested on the circumferential surface 21. 4, once again the tail end of the fish fillet with its skin penetrates into a recess 25, immediately by means of the pressing surface 42 lying under the cut 41, a clamping of the skin is made, which permits the cut 41 to penetrate between the skin and the silver layer of the fish fillet. separation of the fish meat from the skin. This process occurs with great certainty when the fish fillet is widely distributed from the feed belt 1. The pressure roller 5 located above the cut 41 is particularly effective when there are irregularities in the position of the fish fillet. A guiding surface 7, which is therefore located, appears 8 instead

Thereby, the course of the scavenging process can be further enhanced by an oscillatory movement of the guide surface 7 in the feed direction of the fish fillets.
