INDRETNING TIL ENKELTVIS FREMFØRING AF FISKDEVICE FOR SINGLE FEEDING OF FISH

Opfindelsen vedrører en indretning til enkeltvis fremføring af fisk i stilling med hovedet fremad, i forudbestemt takt 5 og i defineret position under angreb i området ved hovedet eller kropsdele, der ligger i nærheden af dette område, med et langtrug til føring og paratstilling af fisken, såvel som med en til langtrugets udløbsområde hørende fremføringsindretning med mindst en medbringer, som træder i 10 virksom forbindelse med en fisk, der står parat, med henblik på dennes fremføring.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a device for individually feeding fish in head-forward position, at a predetermined rate 5, and in defined position during attack in the area of the head or body parts adjacent to this area, with a long back for guiding and preparing the fish. as well as with a feeding device belonging to the long-range catchment area with at least one carrier which enters into effective contact with a standing fish for the purpose of feeding it.

Sådanne indretninger kendes i mangfoldige varianter, hvorved den mest udbredte udførelse for eksempel fremgår af DE 15 patentskrift nr. 1 293 416.Such devices are known in a variety of variants, the most widespread embodiment being shown, for example, in DE 15 patent no. 1 293 416.

Ved dette koncept bliver den nederste af fiskene, der ligger i et magasin stablet mod et anslag, der kan svinges ud, trukket ud ved hjælp af en på et takthjuls omkreds anbragt 20 torn under fortrængning af anslaget. Dette sker derved, at tornen rager ud opad gennem en slids, der befinder sig i magasinbunden. Udtagningstakten sættes af takthjulets omdrejningstal, og udtagningen sker ved gribning ved hovedet.In this concept, the bottom of the fish lying in a magazine stacked against a catchable swivel is pulled out by means of a 20 turret perpendicular to a stroke wheel displaced by the impact. This is because the thorn protrudes upwards through a slot located in the bottom of the magazine. The take-off rate is set by the speed of the clock wheel and the take-out is done by gripping the head.

Den grebne fisk bliver så efter fritrækningen og accelera-25 tion frigivet ved, at tornen dykker væk, så fisken ved hjælp af den tildelte kinetiske energi via en fiskesliske kommer ned i trug, der føres på tværs forbi slisken.The trapped fish are then released after the free-pulling and acceleration by the thorns diving away, so that the fish, via the assigned kinetic energy, via a fish slice, descends into the trough that is passed across the slice.

Ved indretninger ifølge dette koncept kommer det ofte til 30 uregelmæssigheder, som hidrører fra, at den af anslagsmekanismen bestemte venteposition er forskellig med hensyn til fiskestørrelse, så også tornens angrebspunkt på fiskehovedet er forskelligt. Derudover bevirker accelerationen af den grebne fisk og tilbageholdemodstanden fra anslagsmeka-35 nismen en påvirkning, som ofte fører til kvalitetsforrin- 2 DK 171389 B1 gende beskadigelser af slutproduktet. Disse mangler optræder især ved høje taktydelser, og en videregivelse sker ikke i en defineret position.In devices according to this concept, there are often 30 irregularities that result from the waiting position determined by the impact mechanism being different in fish size, so also the thorn attack point on the fish head is different. In addition, the acceleration of the seized fish and the retention resistance of the impact mechanism exert an effect, which often leads to quality degradation of the final product. These deficiencies occur especially at high rate services, and a transfer is not done in a defined position.

5 Fra DE patentskrift nr. 15 79 590 kendes endvidere en indretning, ved hvilken der i et magasins udløbsområde er anbragt et par intermittent drevne, elastisk deformerbare ruller med udsparinger, som i hvilestilling danner en optagetragt for hovedet af fisken, der står parat med hovedet 10 fremad. Enkeltopdelingen sker ved modsat drejning af rullerne, hvorved torne, der findes på disse, skal iværksætte den sikre gribning af fisken.Furthermore, from DE patent specification No. 15 79 590 there is known a device in which a pair of intermittently driven, elastically deformable rollers with recesses are arranged in the outlet area of the magazine, which in a resting position forms a take-up funnel for the head of the fish which stands ready with the head 10 forwards. The single division occurs by the opposite rotation of the rollers, whereby thorns found on these should initiate the safe gripping of the fish.

Også denne indretning har en tendens til uregelmæssigheder, 15 da fisken, der står parat, ikke gribes sikkert uden torne, og med torne frembringes de omtalte beskadigelser, som i dette tilfælde er endnu mere tungtvejende, da tornene praktisk taget gennemtrænger fisken. Der sker heller ikke en videregivelse i defineret position.This device also tends to irregularities, since the standing fish are not safely seized without thorns, and with thorns the said damage is produced, which in this case is even more weighty as the thorns virtually penetrate the fish. There is also no transfer in a defined position.

Det er opfindelsens opgave at foreslå en indretning til taktvis enkeltfremføring af fisk, hvilken indretning især er egnet til håndtering af småfisk ved ekstremt høj ydelse og derved muliggør en meget nøjagtig bearbejdning af hver 25 fisk.It is the object of the invention to propose a device for temporarily single feeding of fish, which device is particularly suitable for handling small fish at extremely high yields, thereby enabling very accurate processing of every 25 fish.

Denne opgave løses ved en indretning ifølge den indledende del af krav 1 derved, at langtrugets udløb ender i en tunge, der i det væsentlige fortsætter langtrugets bund, hvil-30 ken tunge langs siderne tilspidser hen mod sin frie ende og er indrettet til at støtte fisken ved dens bug eller ryg, og at medbringeren har et par medbringerelementer, som griber bag om fiskens gællelåg, skulderbæltebue eller hovedskal, hvilke medbringerelementer er styret langs langtru-35 gets og tungens sider, hvis yderflader er udformet som sty- 3 DK 171389 B1 rekurver, idet de følger disses forløb.This task is solved by a device according to the preamble of claim 1, in that the outlet of the long ridge ends in a tongue which substantially continues the bottom of the long ridge, which tongue along the sides tapers towards its free end and is adapted to support the fish at its abdomen or back, and that the carrier has a pair of carrier elements which grip the fish's gill lid, shoulder belt arch or head shell, which carrier elements are guided along the longitudinal and tongue sides, the outer surfaces of which are designed as stiffeners 3 DK 171389 B1 recurs, following their course.

De dermed opnåelige fordele består især deri, at fisken u-afhængigt af størrelse gribes på begge sider sikkert og 5 skånsomt på samme sted i området ved gællerummet, hvorved medbringerens angreb alt efter medbringerens udformning og fiskens bug- eller rygstilling sker bag gællelågene, skulderbæl tebuen eller hovedskallen.The advantages thus obtained consist in particular that, regardless of size, the fish are gripped on both sides securely and gently at the same location in the area of the gill compartment, whereby the carrier's attack, depending on the design of the carrier and the fish's bow or back position, occurs behind the gill lids, the shoulder girdle arch. or the main shell.

10 Der fremkommer en kompakt og enkel opbygning, når medbrin-gerelementerne er bestanddel af et omløbende drevet og under langtruget anbragt rotationslegeme, over hvis periferi de rager op.10 A compact and simple structure emerges when the carrier elements are constituted by a circularly driven and longitudinally arranged rotational body, over whose periphery they protrude.

15 Derved kan medbringerelementerne være udformet fjedrende mod hinanden med indstillelig fjederkraft.In this way, the carrier elements can be formed resilient to each other with adjustable spring force.

Til en nøjagtig forpositionering af fisken for medtagning af medbringerelementerne kan der i den af langtruget be-20 stemte bane for fisken findes et hovedanslag, hvorved dette kan bestå af et par på begge sider af fiskens bane anbragte fangelementer, der kan trænges fra hinanden af fisken mod fjederkraft.For a precise repositioning of the fish to include the guide elements, a main stop may be found in the trajectory of the long-trapped path for the fish, which may consist of a pair of fishing elements arranged on both sides of the fish's trajectory that can be pulled apart by the fish. against spring force.

25 Opfindelsen forklares i det følgende nærmere ved hjælp af et på tegningen vist udførelseseksempel. Der vises i:The invention will now be explained in more detail by means of an exemplary embodiment shown in the drawing. Showing in:

Fig. 1 et aksonometrisk delbillede af indretningen ifølge opfindelsen, 30 fig. 2 et billede fra enden af indretningen set i fiskens fremføringsretning, fig. 3 indretningen i fig. 1 set fra oven.FIG. 1 is an axonometric partial view of the device according to the invention; FIG. 2 shows a view from the end of the device in the direction of feeding of the fish; FIG. 3 shows the device of FIG. 1 from above.

35 4 DK 171389 B1 I et ikke nærmere vist stativ til en indretning til enkeltfremføring af fisk er der på egnet måde anbragt et i længderetning oscillerende drevet langtrug 1 til fremføring og paratstilling af fisken. Langtruget 1 er i tværsnit udfor-5 met kurvebueformet og således dimensioneret, at fisken støttes mellem sidevæggene 2 stående på dens bug eller liggende på ryggen. Langtrugets 1 bund 3 er ved sin i fiskens fremføringsretning forreste ende forlænget ved dannelse af en tunge 4, der tilspidser sig langs siderne. Langtrugets 1 10 underside er over en dellængde forsynet med et nedad ragende kilestykke 5, hvis sider går over i langtrugets 1 sidevægges 2 yderste flader.35 4 DK 171389 B1 In an unspecified stand for a single feeding device, a longitudinally oscillatingly driven long back 1 for feeding and preparing the fish is suitably arranged. The elongated trough 1 is in cross-sectional shape of the curve bow shaped and so dimensioned that the fish is supported between the side walls 2 standing on its belly or lying on its back. The bottom 3 of the longitudinal trough 1 is extended at its forward anterior end by the formation of a tongue 4 which tapers along its sides. The underside of the longitudinal trough 1 10 is provided over a part length with a downwardly projecting wedge piece 5, the sides of which extend into the outermost surfaces of the long trough 1.

Under langtruget 1 er der anbragt et skiveformet rotations-15 legeme 6, som er drevet kontinuerligt eller trinvis omløbende omkring en akse 7, der er vandret og forløber på tværs af fiskens fremføringsretning. Rotationslegemets 6 periferi ligger derved med sit kulminationspunkt i området ved tungen 4, til hvilket formål langtruget 1 er udsparet 20 bueformet ved sin underside, så der mellem dette og rotationslegemet 6 forbliver en spalte 8.Under the longitudinal trough 1 is arranged a disc-shaped rotary body 6 which is driven continuously or incrementally around an axis 7 which is horizontal and extends transversely of the direction of feeding of the fish. The periphery of the rotary body 6 thus lies with its culmination point in the region of the tongue 4, for which purpose the longitudinal trough 1 is recessed 20 arcuate at its underside, so that a gap 8 remains between this and the rotary body 6.

Rotationslegemet 6 er forsynet med medbringere 9, der er forsat 180° i forhold til hinanden. De består hver af et 25 par medbringerelementer 10, som er udformet trådformede og rager stående over for hinanden ud over rotationslegemets 6 periferi. Medbringerelementerne 10 består fortrinsvis af fjedertråd. De er ført i omtrent radialt i rotationslegemets 6 sider indarbejdede noter og indspændt i nærheden af 30 aksen. I hviletilstand bevirker medbringerelementernes 10 egenfjedring, at de berører hinanden ved deres yderste ender over rotationslegemets 6 midterplan.The rotary body 6 is provided with carriers 9 which are set 180 ° relative to each other. They each consist of a pair of carrier elements 10, which are formed in the form of filaments and protrude across from one another beyond the periphery of the rotary body 6. The carrier elements 10 preferably consist of spring wire. They are inserted roughly radially into the 6 sides of the rotary body and incorporated in the vicinity of the 30 axis. In the resting state, the self-suspension of the driver elements 10 causes them to touch each other at their outer ends over the median plane of the rotary body 6.

Til langtruget 1 hører der et hovedanslag 11. Det består af 35 et par på højkant anbragte, fjedrende fangelementer 12, der 5 DK 171389 B1 strækker sig langs langtrugets 1 to sidevægge 2 og derved efterlader en spalte 13 i forhold til sidevæggene 2, som mindst svarer til tykkelsen af medbringerelementerne 10. Fangelementerne 12 er på ikke vist måde indspændt ved deres 5 bageste ender og ved deres forreste ender bøjet indad, så de gensidigt støtter sig mod hinanden foran tungen over rotationslegemets 6 midterplan.The longitudinal trough 1 includes a main stop 11. It consists of a pair of high-resilient, resilient catch elements 12 extending along the two side walls 2 of the long trough 1, thereby leaving a gap 13 with respect to the side walls 2, which at least corresponds to the thickness of the carrier elements 10. The catch elements 12 are in no way clamped at their rear ends and at their front ends bent inwards so that they mutually support each other in front of the tongue over the median plane of the rotary body 6.

Indretningens arbejdsmåde er følgende: En af en ikke vist 10 udrettermekanisme med hovedet forrest og ryg nedad paratstillet fisk kommer ind i langtruget 1 og bliver skubbet fremad på grund af dettes oscillationsbevægelse, indtil dens snude kommer til anslag mod hovedanslaget 11, og fisken dermed står stille. Under dette forløb drejer rotati-15 onslegemet 6 i pilens retning med den virkning, at medbringerelementerne 10 løber på kilestykket 5 og bliver trængt fra hinanden af dette mod deres egenfjedring. Ved videre drejning af rotationslegemet 6 dykker medbringerelementerne 10 ind i spalten 13 mellem langtrugets 1 sidevægge 2 og ho-20 vedanslagets 11 fangelementer 12 og bevæger sig ind i området med tungen 4, på hvilken fisken ligger an med sin hovedskal. Ligesom føringen af medbringerelementerne 10 indtil da skete ved hjælp af sidevæggene 2, overtager tungen 4 nu denne opgave med sine sider, så medbringerelemen-25 terne 10 på grund af den tilspidsede udformning af tungen 4 nænner sig hinanden med hensyn til afstand. De når derved til slut en gensidig afstand, der er mindre end fiskens tykkelse, så denne gribes fortrinsvis bag gællelågene, skulderbæltebuen eller hovedskallen. Den deraf resulterende 30 medbringning af fisken bevirker nu, at denne overvinder hovedanslaget 11 under fortrængning af fangelementerne 12 og trækkes ud af langtruget 1, hvorved det fremførende angreb sker symmetrisk på begge sider af fisken og dermed ikke alene skånsomt på samme sted, men også sikkert, da en und-35 vigning af fisken og afglidning af medbringerelementerne 10 6 DK 171389 B1 praktisk taget ikke er mulig. Den på denne måde med hensyn til takt og position nøjagtigt udtagne fisk kan frigives af en ikke vist udspilingsstyring af medbringerelementerne 10. Derved sker der ved kontinuerlig drejning af rotationslege-5 met 6 kun en taktvis afgivelse, medens der ved drejevinkel-styret drivning består den mulighed at gennemføre arbejdsgange på fisken, som for eksempel afskæring af hovedet, under udnyttelse af den positionsnøjagtige paratstilling.The method of operation of the device is as follows: One of a 10 straightening mechanism not shown with the head front and back down prepared fish enters the longitudinal trough 1 and is pushed forward due to its oscillatory movement until its muzzle hits the main strike 11 and the fish is thus stationary . During this course, the rotating body 6 rotates in the direction of the arrow with the effect that the carrier elements 10 run on the wedge piece 5 and are pulled apart by this against their own suspension. Upon further rotation of the rotary body 6, the carrier elements 10 dive into the gap 13 between the longitudinal walls 2 of the longitudinal 1 and the catching elements 12 of the main stop 11 and move into the region of the tongue 4 on which the fish rests with its head shell. Just as the guiding of the carrier elements 10 until then occurred by means of the side walls 2, the tongue 4 now assumes this task with its sides, so that the carrier elements 10, due to the tapered configuration of the tongue 4, approach each other with respect to distance. Finally, they reach a mutual distance less than the thickness of the fish, so that it is preferably gripped behind the gill lids, shoulder girdle arch or head shell. The resultant entrainment of the fish now causes it to overcome the main strike 11 during displacement of the catch elements 12 and be pulled out of the long trough 1, whereby the advancing attack occurs symmetrically on both sides of the fish and thus not only gently in the same place, but also safely , since an avoidance of the fish and slip of the carrier elements 10 6 is practically not possible. The fish, in this way, precisely taken out for stroke and position, can be released by a not shown play-out control of the carrier elements 10. Thereby, in continuous rotation of the rotary body 6, only a tempo- rary release occurs, while in the rotation angle controlled operation it the ability to perform workflows on the fish, such as cutting off the head, utilizing the position-accurate readiness.

10 Indretningen er særligt egnet til håndtering af små massefisk, hvorved det på enkel måde er muligt at opnå en præstationsforøgelse ved parallelkobling af flere indretninger af den beskrevne slags.The device is particularly suitable for handling small mass fish, whereby it is easily possible to achieve an increase in performance by parallel coupling of several devices of the type described.
