Abstract

Skin (16) is removed from a pelt animal body (17) being firstly freed from the rear legs. The skinned part of the body is inserted between a pair of belt or chain conveyors (10), whilst the freed skin edge is drawn in the opposite direction. Tendons or other particularly strong connections between the skin and the body are severed by one or more laser beams or mechanical cutters (12). The laser beams or mechanical cutters are remotely controlled so that an operator does not come into contact with the skin or pelt animal body.

Fremgangsmåde og apparat til at trække skindet af en pelsdyrkropMethod and apparatus for pulling the skin of a fur animal body

Den foreliggende opfindelse angår en fremgangsmåde til at trække skindet af en pelsdyrkrop, ved hvilken fremgangsmåde skindet efter at være blevet frigjort ved 5 bagbenene krænges således, at skindets kødside kommer til at vende udefter, og at der på det sted, hvor adskillelsen mellem skind og krop finder sted, dannes en skindfold, hvorefter skindet trækkes fri af kroppen, idet sener og andre særligt stærke forbindelser mellem skind og pelsdyrkrop overskæres ved hjælp af skæreorganer.The present invention relates to a method of pulling the skin of a fur animal body, in which the skin, after being released at the hind legs, is heeled so that the flesh side of the skin is facing outward, and that at the site where the separation between the skin and the body takes place, a skin fold is formed, after which the skin is pulled free from the body, cutting tendons and other particularly strong connections between the skin and the fur animal body by means of cutting means.

10 Det er kendt at trække skindet af pelsdyr på denne måde. Det kan enten ske helt manuelt, idet pelsdyret hænges op i bagbenene, og skindet efter at være blevet frigjort ved bagbenene krænges og manuelt trækkes af kroppen. Der kendes også apparater i hvilke den kraft, der er nødvendig for at trække skindet af dyrekroppen, udøves ved hjælp af en pneumatisk cylinder. Dyrekroppen ophænges så ved bagbenene i et ophæng, medens den 15 krængede, frigjorte skindrand fastgøres til gribeorganer, der derefter forskydes i forhold til ophænget i pelsdyrkroppens længderetning. I området ved pelsdyrets hoved, såsom ved ører, mundvige og læber, findes der imidlertid sener eller andre særligt stærke forbindelser mellem skindet og petsdyrkroppen, der hindrer at skindet uden videre kan trækkes helt af kroppen. Ved de kendte metoder løses problemet ved at en operatør ved hjælp af en 20 almindelig kniv overskærer disse sener eller forbindelser. Ved et sådant arbejde kommer operatøren med sine hænder i direkte kontakt med den afskindede pelsdyrkrop, og arbejdet er derfor både trættende og snavset, hvorfor det er svært at finde arbejdskraft til at løse opgaven.10 It is known to pull the fur of fur animals in this way. It can either be done completely manually, with the fur animal hanging up in the hind legs and the skin after being released by the hind legs being heeled and pulled manually by the body. Also known are apparatus in which the force required to pull the skin off the animal body is exerted by a pneumatic cylinder. The animal body is then suspended at the hind legs in a suspension, while the heeled, released skin edge is attached to gripping means which are then displaced relative to the longitudinal direction of the fur animal body. However, in the area at the head of the fur animal, such as at the ears, mouths and lips, tendons or other particularly strong connections exist between the skin and the pet animal body, which prevent the skin from being pulled completely from the body. In the known methods, the problem is solved by an operator cutting through these tendons or connections by means of a common knife. In such work, the operator comes into direct contact with the skinned fur body, and the work is therefore both tiring and dirty, which is why it is difficult to find labor to solve the task.

25 Problemet løses imidlertid ved fremgangsmåden ifølge opfindelsen, der er ejendommelig ved, at de særlige forbindelser mellem skind og pelsdyrkrop i umiddelbar nærhed af skindfolden overskæres ved hjælp af en eller flere, i forhold til pelsdyrkroppen bevægelige laserstråler eller mekaniske skæreorganer, der fjernstyres således, at en eventuel operatør ikke kommer i berøring med skindet eller pelsdyrkroppen.However, the problem is solved by the method according to the invention, characterized in that the particular connections between skins and fur bodies are cut in the immediate vicinity of the fur fold by means of one or more movable laser beams or mechanical cutting means which are remotely controlled so that any operator does not come in contact with the fur or fur body.

Det har vist sig, at de omtalte sener og særlige forbindelser, der især findes ved pelsdyrets hoved, udmærket kan overskæres ved hjælp af laserstråler, som kan styres, uden at operatøren kommer i berøring med pelsdyret. Der kan alternativt anvendes mekaniske skæreorganer, der kan have en hvilken som helst passende form, og som ved hjælp af 35 mekaniske eller andre former for føringer kan bringes i kontakt med de sener eller forbindelser, der skal overskæres. Aktiveringen af skæreorganerne kan eksempelvis ske manuelt, mekanisk, pneumatisk eller elektrisk.It has been found that the aforementioned tendons and special compounds found especially at the head of the fur animal can be excellently cut by laser beams which can be controlled without the operator contacting the fur animal. Alternatively, mechanical cutting means may be used which may be of any suitable shape and which may be brought into contact with the tendons or joints to be cut by mechanical or other forms. The cutting means can, for example, be activated manually, mechanically, pneumatically or electrically.

Fjernstyringen af skæreorganerne kan eksempelvis ske ved hjælp af en stråle af synligt 40 eller ikke synligt lys eller ved hjælp af en laserstråle. Således kan operatøren med strålen pege på det sted, hvor skæreoperationen skal finde sted, eller pi anden måde lede skæreorganerne hen til skærestedet.For example, the remote control of the cutting means may be effected by means of a beam of visible light or invisible light or by means of a laser beam. Thus, with the jet, the operator may point to the location where the cutting operation is to take place, or otherwise guide the cutting means to the cutting site.

2 DK 174847 B12 DK 174847 B1

Som en anden af mange muligheder kan skindaftrækningsoperationen afbildes på en billed- eller fjernsynsskærm, og operatøren kan så ved at følge med på denne skærm styre skæreorganernes funktion. Eksempelvis kan skærmen være en såkaldt "touch screen”, hvor operatøren med en finger eller "pegepind" kan berøre skærmen for at angive det sted 5 på dyrekroppen, hvor der skal foretages en skæreoperation.As another of many possibilities, the skin extraction operation can be depicted on a picture or television screen, and the operator can then, by following this screen, control the function of the cutting means. For example, the screen may be a so-called "touch screen" where the operator with a finger or "pointer" can touch the screen to indicate the location 5 on the animal body where a cutting operation is to be performed.

Når skindet ved fremgangsmåden ifølge opfindelsen trækkes fri af pelsdyrkroppen ved, at den frigjorte ende af skindet og den afskindede ende af pelsdyrkroppen bevæges i forhold til hinanden, sker denne relative bevægelse hensigtsmæssigt således, at positionen af den 10 fold, der på det krængede skind dannes på det sted, hvor adskillelsen mellem skind og krop finder sted, er» hovedsagen stationær. Dette kan eksempelvis opnås ved, at den frigjorte ende af skindet og den afskindede ende af pelsdyrkroppen bevæges i modsatte retninger med i hovedsagen samme hastighed. Da overskæringen af sener og andre særlige forbindelser skal foregå i umiddelbar nærhed af den nævnte fold, opnår man, at 15 skæreorganerne kun behøver at blive bevæget i et enkelt plan på tværs af de modsat rettede bevægelser af den frigjorte ende af skindet og af den afskindede ende af pelsdyrkroppen i retning mod og bort fra pelsdyrkroppen.When the fur of the method according to the invention is pulled free of the fur animal body by moving the released end of the fur and the skinned end of the fur animal body, this relative movement is conveniently done so that the position of the 10 fold formed on the heeled fur at the place where the separation between skin and body takes place, 'the main thing is stationary. This can be achieved, for example, by moving the released end of the skin and the skinned end of the fur animal body in opposite directions at substantially the same speed. Since the cutting of the tendons and other special joints is to take place in the immediate vicinity of said fold, it is obtained that the cutting means need only be moved in a single plane across the opposite directed movements of the released end of the skin and of the sheathed end of the furry body toward and away from the furry body.

Ved det ovennævnte kendte apparat, hvor pelsdyrkroppen ved bagbenene fastgøres til et 20 ophæng, er det nødvendigt at anvende særlige støtteorganer, som under den sidste del af skindaftrækningsprocessen bevæges ind mod den forreste del af pelsdyrkroppen for at fastholde denne. Uden sådanne særlige støtteorganer ville der være risiko for, at pelsdyrkroppen blev revet midt over, inden skindet var blevet trukket fri af pelsdyrets hoved. Dette problem kan løses ved fremgangsmåden ifølge opfindelsen derved, at den 25 afskindede ende af pelsdyrkroppen bringes i indgreb med og bevæges af en kæde eller på en transportør. Derved bliver pelsdyrkroppen understøttet og fastholdt langs en større og større del af kroppen, efterhånden som processen skrider frem. Endvidere kan transportøren aflevere den afskindede pelsdyrkrop i fx en affaldsbeholder.In the aforementioned known apparatus, in which the fur animal body at the hind legs is attached to a suspension, it is necessary to use special support means which, during the latter part of the skin extraction process, move towards the front part of the fur animal body to retain it. Without such special support organs, there would be a risk that the fur animal body would be torn in the middle before the fur was pulled off the fur animal's head. This problem can be solved by the method according to the invention in that the shelled end of the fur animal body is engaged and moved by a chain or on a conveyor. As a result, the fur animal body is supported and maintained along a larger and larger part of the body as the process progresses. Furthermore, the carrier can deliver the skinned fur animal body in, for example, a waste container.

30 Selve overskæringen af senerne eller de særlige forbindelser kan som antydet ovenfor ske ved, at et eller flere skæreorganer bevæges ind mod den afskindede dei af dyrekroppen i umiddelbar nærhed af den fold, der dannes på det krængede skind. Disse skæreorganer kan som nævnt ovenfor omfatte en indretning til frembringelse af laserstråler, ligesom de kan omfatte roterende, vibrerende og/eller frem- og tilbagegående skæreorganer, fx i form 35 af knive, save eller skæretråde.The cutting of the tendons or special connections itself can be effected as indicated above by moving one or more cutting means towards the sheathed part of the animal body in the immediate vicinity of the fold formed on the heeled skin. These cutting means may, as mentioned above, comprise a device for producing laser beams, as well as may include rotating, vibrating and / or reciprocating cutting means, for example in the form of knives, saws or cutting wires.

Opfindelsen angår også et apparat til at trække skindet af en pelsdyrkrop og omfattende første og andre gribeorganer indrettet til at indgribe med henholdsvis en afskindet del af pelsdyrkroppen og en frigjort, krænget del af skindet med udadvendende kødside og 40 bevægeorganer indrettet til at til at bevæge de første og andre gribeorganer i forhold til hinanden således, at skindet trækkes fri af pelsdyrkroppen, idet der på det sted, hvor adskillelsen mellem skind og krop finder sted, dannes en skindfold, og apparatet ifølge opfindelsen er ejendommeligt ved i forhold til pelsdyrkroppen bevægelige skæreorganer indrettet til at overskære sener og andre særligt stærke forbindelser mellem skind og 3 DK 174847 B1 pelsdyrkrop i umiddelbar nærhed af skindfolden, hvilke skaereorganer er indrettet til frembringelse af en eller flere laserstråler eller har form af mekaniske skæreorganer, og ved fjernstyringsmidler indrettet til at fjernstyre skæreorganerne således, at en eventuel operatør ikke kommer i berøring med skindet eller pelsdyrkroppen.The invention also relates to an apparatus for pulling the skin of a fur animal body and comprising first and second gripping means adapted to engage, respectively, a skinned part of the fur animal body and a detached, curved part of the skin with outward facing meat and 40 moving means adapted to move the fur. first and second gripping means relative to each other such that the skin is pulled free of the fur animal body, a skin fold being formed at the place where the separation between the skin and the body and the apparatus according to the invention are arranged by means of movable cutting means arranged in relation to the fur animal body for cutting tendons and other particularly strong connections between skins and furry bodies in the immediate vicinity of the skins fold, which cutting means are adapted to produce one or more laser beams or in the form of mechanical cutting means, and by remote control means arranged to remotely control the cutting means thus , that an ev lone operator does not come in contact with the fur or fur body.

5 I den foreliggende sammenhæng skal udtrykket "fjernstyret" betyde en styring, der gør det muligt for en eventuel operatør under skasreprocessen at undgå direkte berøring med pelsdyrkroppen eller pelsdyrskindet. Der kan således være tale om en manuel styring af skæreorganerne via mekaniske føringer eller led. Det er imidlertid også muligt at 10 konstruere apparatet således, at det arbejder hel- eller halvautomatisk. Eksempelvis kan apparat omfatte en pneumatisk eller elektronisk styreenhed, der aktiverer skæreorganerne, når modstanden mod aftrækning af skindet overstiger en forudbestemt værdi. Ud fra et forudgående kendskab til anatomien for den pelsdyrart, der behandles, kan styreindretningen være programmeret til at bevæge skæreorganerne mod netop de 15 steder, hvor der skal ske en overskæring, for at aftrækn ingsprocessen kan fortsætte.5 In the present context, the term "remotely controlled" is intended to mean a control which allows any operator during the scraping process to avoid direct contact with the fur animal body or the fur animal skin. Thus, this can be a manual control of the cutting means via mechanical guides or joints. However, it is also possible to construct the apparatus so that it operates fully or semi-automatically. For example, the apparatus may comprise a pneumatic or electronic control unit which activates the cutting means when the resistance to pulling the skin exceeds a predetermined value. From a prior knowledge of the anatomy of the fur species being treated, the control device may be programmed to move the cutting means toward precisely the 15 places where a cutting is to occur in order for the peel process to proceed.

Apparatet kan ifølge opfindelsen have styreorganer indrettet til at styre den relative bevægelse af de første og andre gribeorganer således, at positionen af den fold, der på det krængede skind dannes på det sted, hvor adskillelsen mellem skind og krop finder sted, 20 forbliver i hovedsagen stationær.The apparatus according to the invention may have control means arranged to control the relative movement of the first and second gripping means such that the position of the fold formed on the heeled skin at the place where the separation between skin and body 20 remains substantially stationary.

De første gribeorganer kan ifølge opfindelsen omfatte en kæde- eller båndtransportør.The first gripping means according to the invention may comprise a chain or belt conveyor.

Denne transportør, på hvilken der fortrinsvis findes pigge eller andre friktionsforøgende organer, kan samarbejde med en plade eller et andet modhold. Ved den foretrukne 25 udførelsesform omfatter de første gribeorganer imidlertid to med indbyrdes tværgående afstand anbragte kæde- eller båndtransportører, hvis over for hinanden beliggende løb er indrettet til at gribe omkring den afskindede del af dyrekroppen. Disse to samvirkende transportører er fortrinsvis også forsynet med pigge eller andre friktionsforøgende organer.This conveyor, on which are preferably spikes or other friction-increasing means, can cooperate with a plate or other restraint. However, in the preferred embodiment, the first gripping means comprise two spacer or belt conveyors spaced apart, the opposite runs of which are arranged to engage the sheathed portion of the animal body. These two cooperating conveyors are also preferably provided with spikes or other friction enhancing means.

30 Apparatet kan endvidere omfatte føreorganer, der er indrettet til at føre et eller flere skæreorganer ind mod og bort fra den afskindede del af dyrekroppen i umiddelbar nærhed af den fold, der dannes på det krængede skind, hvorved sener og lignende forbindelser mellem skindet og kroppen kan overskæres. Dette kan ske ved, at dyrekroppen enten bevæges i forhold til stationære skæreorganer eller at skæreorganerne bevæges i forhold 35 til dyrekroppen. I sidstnævnte tilfælde kan føreorganerne eksempelvis omfatte en eller flere svingbare arme, på hvilke skæreorganerne er anbragt således, at de kan svinges mellem en inaktiv stilling, i hvilken de ligger i afstand fra dyrekroppen, og en aktiv stilling, i hvilken de er i kontakt med den afskindede del af dyrekroppen i umiddelbar nærhed af den fold, der dannes på det krængede skind.The apparatus may further comprise guide means adapted to guide one or more cutting means towards and away from the sheathed portion of the animal body in the immediate vicinity of the fold formed on the heeled skin, thereby making tendons and similar connections between the skin and the body. can be cut. This can be done by either moving the animal body relative to stationary cutting means or moving the cutting means relative to the animal body. In the latter case, for example, the guide means may comprise one or more pivotable arms on which the cutting means are arranged so that they can be pivoted between an inactive position in which they are distant from the animal body and an active position in which they are in contact with the the sheathed portion of the animal body in the immediate vicinity of the fold formed on the heeled skin.

Da sener og andre særlige forbindelser, der eksempelvis findes ved pelsdyrets ører, mundvige, læber etc. er beliggende i hovedsagen symmetrisk forhold til et symmetriplan for pelsdyrkroppen, er også føreorganerne hensigtsmæssigt anbragt symmetrisk omkring dette symmetriplan. Eksempelvis kan føreorganerne omfatte to svingbare arme, der er 4 DK 174847 B1 svingbare mod og bort fra hinanden i hovedsagen symmetrisk i forhold til pelsdyrkroppens symmetriplan, og de svingbare arme kan være fjederpåvirket i retning mod deres inaktive stilling. Nar skaereorganerne skal aktiveres, kan dette ske ved, at armene i retning mod fjederkraften bevæges i kontakt med pelsdyrkroppen.Since tendons and other special compounds found, for example, at the fur, ears, mouth, lips, etc. of the fur animal are substantially symmetrical to a plane of symmetry of the fur animal, the guide means are also suitably arranged symmetrically about this plane of symmetry. For example, the guide means may comprise two pivotal arms which are pivotal toward and away from each other substantially symmetrical to the plane of symmetry of the fur animal body, and the pivotal arms may be spring-actuated toward their inactive position. When the cutting means must be activated, this can be done by moving the arms in the direction of the spring force in contact with the fur animal body.

Opfindelsen vil i det følgende blive nærmere forklaret under henvisning til tegningen, på hvilken fig. 1 skematisk viser en udførelsesform for apparatet ifølge opfindelsen under brug, og fig. 2 skematisk viser et snit efter linien II-II i fig. 1.The invention will now be explained in more detail with reference to the drawing, in which: FIG. 1 schematically shows an embodiment of the apparatus according to the invention in use; and FIG. 2 schematically shows a section along line II-II in FIG. First

1010

Det i fig. 1 viste apparat har et par lodrette bånd- eller kædetransportører 10, på hvis ydre overflade der er udformet pigge 11 eller andre friktionsforøgende organer. Under båndtransportørerne er der monteret et par rundsave eller rundknive 12, der hver især drives af en elektromotor 13. En gribeindretmng 14 kan ved hjælp af en ikke vist 15 pneumatisk eller hydraulisk cylinder bevæges i op- og nedadgående retning.The FIG. 1, a pair of vertical belt or chain conveyors 10, on the outer surface of which is formed spikes 11 or other friction-increasing means. Under the belt conveyors are mounted a pair of circular saws or circular knives 12, each driven by an electric motor 13. A gripping device 14 can be moved upwards and downwards by means of a pneumatic or hydraulic cylinder not shown.

Et pelsdyr 15, der skal behandles i det illustrerede apparat, har manuelt eller i et andet apparat fået skindet 16 frigjort ved bagbenene. Den afskindede bageste del af pelsdyrkroppen 17 føres nu ind mellem de to transportører 10, og gribeindretningen 14 20 fastgøres til den ved bagbenene frigjorte skindkant. Derefter bringes båndtransportørerne 10 til at bevæge sig i den med pilene viste retning og gribeindretningen 14 bevæges samtidigt nedefter ved hjælp af den ikke viste cylinder, som det i fig. 1 er antydet med en pil. Derved trækkes pelsdyrskindet 16, der er kraenget og har kødsiden vendede udefter, af pelsdyrkroppen 17.A fur animal 15 to be treated in the illustrated apparatus has manually or in another apparatus had the skin 16 released at the hind legs. The skinned rear portion of the fur animal body 17 is now inserted between the two conveyors 10, and the gripping device 14 20 is secured to the skin edge released by the hind legs. Thereafter, the belt conveyors 10 are moved in the direction shown by the arrows and the gripping device 14 is simultaneously moved downwards by means of the cylinder not shown, as in FIG. 1 is indicated by an arrow. Thereby, the fur animal fur 16, which is heeled and has the meat side facing outwards, is pulled by the fur animal body 17.

25 I dyrets hals- og hovedregioner er skindet 16 på visse steder forbundet med kroppen ved hjælp af sener 18 (fig. 2) eller andre særligt stærke fobindelser, der ikke uden videre kan overrives. Nar sådanne sener er blevet blottet oven over den rundtgående skindfold 19, der dannes som følge af krængningen af skindet, aktiveres skæreorganerne 12 på 30 passende måde og bringes fra modstående sider i berøring med pelsdyrkroppen 17 på det sted, hvor senerne 18 er beliggende. Nar senerne er overskåret, føres skæreorganerne tilbage, og afdækningsprocessen fortsætter.25 In the neck and head regions of the animal, the skin 16 is in some places connected to the body by means of tendons 18 (Fig. 2) or other particularly strong phobic connections which cannot be overstated. When such tendons have been exposed above the circumferential skin fold 19 formed as a result of the heel of the skin, the cutting means 12 are appropriately activated and contacted from opposite sides with the fur animal body 17 at the site where the tendons 18 are located. When the tendons are cut, the cutting means are returned and the covering process continues.

Fig. 2 illustrerer skematisk et snit efter linien II-II i fig. 1. Rundsavene eller rundknivene 35 12 er her drejeligt monteret på et par svingarme 20, der er indbyrdes forbundet ved hjælp af en fjeder 21. Svingarmene 20 er ved hjælp af et mellemstykke 22 forbundet med en stempelstang 23 for en ikke vist pneumatisk eller hydraulisk cylinder.FIG. 2 schematically illustrates a section along line II-II of FIG. 1. The circular saws or circular knives 35 12 are here rotatably mounted on a pair of pivot arms 20 which are interconnected by means of a spring 21. The pivot arms 20 are connected by means of an intermediate piece 22 to a piston rod 23 for a pneumatic or hydraulic cylinder not shown. .

Nar skindaftrækntngsprocessen standser på grund af sener 18, der ikke umiddelbart kan 40 overrives, aktiveres den pneumatiske cylinder således, at svingarmene 20 og dermed knivene eller rundsavene 12 bringes i berøring med dyrekroppen 17 umiddelbart oven over skindfolden 19. Fjederen 21 sikrer, at knivene 12 holdes i kontakt med dyrekroppen, så at senerne 18 overskæres. Derefter kan stempelstangen 23 af cylinderen føres tilbage til en inaktiv stilling.When the skin extraction process stops due to tendons 18 which cannot be immediately torn, the pneumatic cylinder is actuated so that the swing arms 20 and thus the knives or circular saws 12 are brought into contact with the animal body 17 immediately above the skin fold 19. The spring 21 ensures that the knives 12 is kept in contact with the animal body so that the tendons 18 are cut. Thereafter, the piston rod 23 of the cylinder can be returned to an inactive position.
