Den foreliggende opfindelse angår et apparat til opskæring af skindet af pelsdyr, navnlig på bagpartiet af mink, og af den i indledningen til krav 1 angivne art.The present invention relates to an apparatus for cutting the fur of fur animals, in particular on the rear part of mink, and of the kind specified in the preamble of claim 1.

5 Ved pelsning, dvs. flåning af pelsdyr - f.eks. mink, udføres indledningsvis et snit tværs over dyrets bagparti, idet der ved hjælp af en kniv udføres et snit fra bagpote til bagpote, idet den ene bagpote - med trædepuden opad - fastklemmes i en holder og den anden bagpote manuelt udrykkes således, at bag-10 benene trækkes ud fra hinanden, hvorefter nævnte snit udføres langs bagsiden af benene og under dyrets endetarmsåbning. Efterfølgende udføres to korte snit fra en position umiddelbart over endetarmsåbningen og skråt nedad til førstnævnte snit, dvs. således at skindet friskæres fra endetarmsåbningen, der 15 forbliver i forbindelse med dyrekroppen.5 For fur, ie. skinning of fur animals - e.g. initially, a cut is performed across the hind portion of the animal, with the aid of a knife, a cut from the hind paw to the hind paw is performed, one hind paw - with the foot pad upwards - clamped in a holder and the other hind paw is manually extended so that the hind paw The 10 legs are pulled apart and said cut is performed along the back of the legs and below the rectum of the animal. Subsequently, two short incisions are made from a position immediately above the rectum and obliquely down to the first incision, i. so that the skin is cut off from the rectum which remains in contact with the animal body.

Som nævnt udføres dette arbejde sædvanligvis manuelt; men det skal nævnes, at der fra beskrivelsen til DK patentansøgning nr. 6498/88 kendes et apparat, der er indrettet til brug ved 20 udførelse af den nævnte opskæring af bagpartiet af pelsdyr. Dette apparat omfatter to holdeorganer, der er indrettet til at fastklemme bagpoterne, og som kan forskydes symmetrisk udad i forhold til hinanden på en glideføring, hvorpå desuden findes en forskydelig, roterende knivmekanisme til udførelse af 25 nævnte tværsnit fra bagpote til bagpote og under endetarmsåbningen .As mentioned, this work is usually done manually; but it should be mentioned that from the description to DK patent application no. 6498/88 there is known an apparatus adapted for use in performing the said cutting of the rear portion of fur animals. This apparatus comprises two retaining means which are arranged to clamp the hind legs and which can be symmetrically displaced outwardly relative to one another on a sliding guide, on which is also provided a slidable, rotary knife mechanism for performing said cross-section from hind leg to hind leg and under the rectum opening.

Opfindelsen har til formål at angive et forbedret apparat af den nævnte kendte type, og som ved hjælp af enkle foranstalt-30 ninger gør det muligt på mere præcis måde at mekanisere den nævnte opskæring af skindet på bagpartiet af pelsdyr, navnlig mink, og som desuden samtidigt kan løsne skindet fra bagpartiet.The invention has for its object to provide an improved apparatus of the known type and which, by means of simple measures, makes it possible to more accurately mechanize said cutting of the skin on the back part of fur animals, especially mink, and which furthermore at the same time can detach the skin from the back.

Hensigtsmæssigt er apparatet udformet således, at det yderligere knivorgan med tilhørende holdeorgan er indrettet til at placeres ud for haleroden af det opskårne bagparti for fiksering af halen af pelsdyret i holdeorganet mod en kniv, der er 5 indrettet til at udføre et snit langs undersiden af halen, når denne ved forskydning af holde- og knivorganet bort fra bagpartiet føres forbi kniven.Conveniently, the apparatus is designed such that the additional knife means and associated holding means are arranged to be positioned off the tail root of the cut rear portion for fixing the tail of the fur animal in the holding means to a knife adapted to make a cut along the underside of the tail. , when it is moved away from the rear portion by displacing the holding and knife means past the knife.

Det andet skindløsneorgan er fortrinsvis udformet således, at 10 det omfatter to par af indbyrdes forskydelige, svingbare gri-befingre, der er indrettet til at indføres i det opskårne bagparti, at sammenklemmes om bagbenene ved deres basis og at føres udad mod de respektive poter og eventuelt tilbage igen.The second skin release means is preferably configured such that it comprises two pairs of mutually displaceable, pivotable grippers arranged to be inserted into the cut back portion, to be clamped about the hind legs at their base and to extend outwardly toward the respective legs and possibly back again.

15 Med henblik på også at mekanisere af trækningen af skindet fra halen kan apparatet med fordel være udformet således, at det omfatter et yderligere skindløsneorgan, der fortrinsvis er sammenbygget med det første skindløsneorgan, og som med en svingbar krogdel, når det første skindløsneorgan er indført 20 mellem skindet og bugsiden af dyrekroppen, er indrettet til at gribe omkring roden af halebenet for frigøring af det opskårne skind fra halebenet, når det yderligere skindløsneorgan føres bort fra dyrekroppen.Advantageously, in order to also mechanize the pulling of the skin from the tail, the apparatus may be designed to comprise an additional skin release means, preferably joined to the first skin release means, and having a pivotable hook portion when the first skin release means is introduced. 20 between the skin and the bow side of the animal body, is arranged to engage the root of the tailbone to release the cut skin from the tailbone as the further skinless member is removed from the animal body.

25 Opfindelsen forklares i det følgende nærmere i forbindelse med tegningen, der viser en udførelsesform for et apparat ifølge opfindelsen.BRIEF DESCRIPTION OF THE DRAWINGS The invention is explained in more detail below with reference to the drawing, which shows an embodiment of an apparatus according to the invention.

Det viste apparat 2 omfatter en apparatstel 4 med to gavle 6, 30 hvorimellem er fastgjort en vandret føringsstang 8. Foran denne er på forsiden af apparatstellet 4 fastgjort to opstående konsoller 10, hvorimellem er fastgjort en vandret føringsstang 12, der altså er placeret i afstand foran føringsstangen 8 og i en lavere højde end denne.The apparatus 2 shown comprises an apparatus frame 4 with two gables 6, 30 between which is mounted a horizontal guide rod 8. Prior to this, two raised brackets 10 are mounted on the front of the apparatus frame 4, between which is mounted a horizontal guide rod 12, which is thus spaced apart. in front of the guide rod 8 and at a lower height than this one.

4 DK 168555 B14 DK 168555 B1

Over føringsstangen 8 er vist en apparatdel 14 med endnu en vandret føringsstang 16, idet apparatdelen 14 er arrangeret svingbar eller på anden måde højdeforskydelig i forhold til apparatstellet 4.Above the guide rod 8 is shown an apparatus part 14 with yet another horizontal guide rod 16, the apparatus part 14 being arranged pivotally or otherwise height-displaceable relative to the apparatus frame 4.

5 På føringsstangen 12 er to holdeorganer 18 forskydeligt lejret ved hjælp af glidebøsninger 20. Holdeorganerne 18 omfatter øvre holdeklemmer 22 betjent af pneumatiske cylindre 24 og beregnet til fastholdelse af hver sin bagpote af et pelsdyrskind 10 26, hvoraf en bageste kropdel som antydet med punkteret streg kan udspændes mellem holdeklemmerne 22 på en sådan måde, at bugsiden af pelsdyrets krop vender ind mod apparatet 2, dvs. således at bagsiden af bagbenene - på i og for sig kendt måde - er udstrammet tilnærmelsesvis retlinet mellem holdeklemmerne 15 22.5 On the guide rod 12, two retaining members 18 are slidably mounted by means of sliding bushings 20. The retaining means 18 comprise upper retaining clips 22 operated by pneumatic cylinders 24 and intended to hold each rear leg of a fur animal skin 10 26, one rear body portion as indicated by a dotted line. can be clamped between the retaining clips 22 in such a way that the bow side of the fur animal's body faces towards the apparatus 2, ie. so that the back of the hind legs - in a manner known per se - is substantially straightened between the retaining clamps 15 22.

Holdeorganerne 18 er indrettet til at forskydes bort fra og imod hinanden ved hjælp af en (ikke vist) pneumatisk cylinder. Mellem konsollerne 10 forløber en endeløs wire 28 over wire-20 hjul 30. Det venstre holdeorgan 18 er forbundet med det nedre løb af wiren 28, medens det højre holdeorgan 18 er forbundet med det øvre løb af wiren 28, således at holdeorganerne 18 ved forskydning på føringsstangen 12 - på i og for sig kendt måde - hele tiden er placeret indbyrdes symmetrisk i forhold til en 25 lodret centerposition 32 af føringsstangen 12.The holding means 18 are arranged to be displaced from and against each other by means of a (not shown) pneumatic cylinder. Between the brackets 10, an endless wire 28 extends over wire-20 wheels 30. The left holding member 18 is connected to the lower barrel of the wire 28, while the right holding member 18 is connected to the upper barrel of the wire 28 so that the holding means 18 are displaced by displacement. on the guide rod 12 - in a manner known per se - is constantly symmetrically relative to a vertical center position 32 of the guide rod 12.

Holdeklemmerne 22 og de tilhørende pneumatik-cylindre 24 er på den side, der vender ind mod centerpositionen 32, forbundet med en basisplade 34 ved hjælp af hængsler 36, således, at 30 holdeklemmerne 22 i brugssituationen svinges indad, når pelsdyrskindet som nævnt udstrammes mellem holdeklemmerne 22 disse kan i modsat retning være fjederpåvirket mod den viste uddrejede postion.The retaining clips 22 and the associated pneumatic cylinders 24 are connected to a base plate 34 by means of hinges 36 on the side facing the center position 32, so that, in the use situation, the retaining clips 22 are pivoted inwardly as the fur animal skin is tensioned between the retaining clamps as mentioned. In the opposite direction, these may be spring-loaded against the turned-out position shown.

Basispladerne 34 er modsat glidebøsningerne 20 holdt i korrekt lodret position ved hjælp af nedre styrehjul 38, der indgriber med en nedre, tværgående forkantdel 40 af apparatstellet 4.The base plates 34 are opposed to the sliding bushes 20 in the correct vertical position by means of lower guide wheels 38 which engage with a lower transverse leading part 40 of the apparatus frame 4.

5 På føringsstangen 8 er forskydeligt lejret en venstre slæde 42, hvorpå er monteret en pneumatisk rotorkniv 44, der i forhold til slæden 42 desuden kan forskydes i højden. På slæden 42 eller evt. på en separat slædedel er monteret et spadeformet skindløsneorgan 46, der ligeledes kan højdeforskydes i 10 forhold til slæden 42.5 On the guide rod 8 is slidably mounted a left carriage 42, on which is mounted a pneumatic rotor knife 44 which, in addition to the carriage 42, can also be displaced in height. On the sleigh 42 or possibly. mounted on a separate carriage part is a spade-shaped skin release means 46 which can also be height-shifted in relation to the carriage 42.

Til højre på føringsstangen 8 er forskydeligt lejret en knivholder 48 for en pneumatisk, skålformet rotorkniv 50, der kan forskydes i højden i forhold til knivholderen 48, samt en slæ-15 de 52 for en pneumatisk rotorkniv 54, hvis cirkulære knivblad står vinkelret på føringsstangen 8, idet knivbladet rager gennem en slidse i bunden af en styrereces af en haleholder 56. Foran denne kan en holderulle 58 svinges indad mod haleholderen 56 for fiksering af halen af pelsdyrskindet mod knivbla-20 det. Rotorkniven 54 og haleholderen 56 kan forskydes i højden i forhold til slæden 52 ved hjælp af en pneumatisk cylinder 60.To the right of the guide rod 8 is slidably mounted a knife holder 48 for a pneumatic, bowl-shaped rotor knife 50 that can be displaced in height with respect to the knife holder 48, and a slide 52 for a pneumatic rotor knife 54 whose circular knife blade is perpendicular to the guide rod 8, the knife blade projecting through a slot at the bottom of a guide recess by a tail holder 56. Prior to this, a holding roller 58 can be pivoted inwardly against the tail holder 56 for fixing the tail of the fur animal skin to the knife blade. The rotor knife 54 and the tail holder 56 can be displaced in height with respect to the carriage 52 by means of a pneumatic cylinder 60.

På føringsstangen 16 af apparatdelen 14 er på glidebøsninger 25 62 svingbart lejret to par krumme fingre 64, der vinkelret på papirets plan har således indbyrdes krumning, at hvert fingerpar 64 - ved nedadføring af apparatdelen 14 kan indføres i det opskårne bagparti af pelsdyret og kan gribe om hvert sit bag ben. Indbyrdes koordineret forskydning af fingerparene 64 30 langs føringsstangen 16 samt gribefunktionen af de krumme fingre 64 udvirkes ved hjælp af pneumatiske cylindre (ikke vist). Evt. kan føringsstangen 16 - som vist punkteret - have svagt nedadrettet V-form, således at de krumme fingerpar 64 lettere kan følge det hængende, udspændte pelsdyrs bagben for 35 frigørelse af skindet derfra.On the guide rod 16 of the appliance part 14, two pairs of curved fingers 64 are pivotally mounted on sliding bushes 62, which are perpendicular to the plane of the paper so that each pair of fingers 64 - when downed by the appliance part 14 can be inserted into the cut rear portion of the fur animal and can grip about each leg behind. Coordinated displacement of the finger pairs 64 30 along the guide rod 16 as well as the gripping function of the curved fingers 64 are effected by means of pneumatic cylinders (not shown). Possibly. For example, the guide rod 16 - as shown punctured - may have a slightly downward V-shape so that the curved finger pairs 64 can more easily follow the hind legs of the hanging, stretched fur animal for release of the skin therefrom.

6 DK 168555 B16 DK 168555 B1

Det spadeformede skindløsneorgan 46 er ved en nedre stump spidsende 66 udformet med W-form, dvs. med en central reces 68, der ved indføring af skindløsneorganet 46 mellem skindet og bugsiden af det opskårne bagparti af pelsdyret kan fange og 5 kan frigøre navle og evt. penis fra skindet. Hvis den centrale reces ikke findes, er der stor risiko for, at pelsdyret ved indføring af skindløsneorganet 46 blot tvinges til en side, således at skindet ikke frigøres korrekt fra navle og evt. penis, dvs. at der er stor risiko for efterfølgende beskadigelse 10 af pelsdyrskindet - ved aftrækning af dette fra dyrekroppen.The spade-shaped skin release means 46 is at a lower blunt tip 66 formed with a W-shape, i.e. with a central recess 68 which, by inserting the skin release means 46 between the skin and the belly side of the cut rear portion of the fur animal, can catch and release navel and possibly. penis from the skin. If the central recess does not exist, there is a great risk that the fur animal upon insertion of the skin release means 46 will simply be forced to one side so that the skin is not properly released from the navel and possibly. penis, ie that there is a great risk of subsequent damage to the fur of the fur - by pulling this from the animal body.

Det påregnes i øvrigt, at apparatet ifølge opfindelsen relativt let vil kunne modificeres til også at udvirke selve af-trækningen af pelsdyr skindet fra dyrekroppen, og evt. vil de 15 krumme fingerpar 64 ved hjælp af særlige klemmekæber ved basis kunne fastholde bagpartiet af dyrekroppen, således at skindet kan aftrækkes derfra ved hjælp af forskydelige gribeorganer, der er indrettet til at fastklemmes omkring pelsdyrskindet f. eks. ved begge sider af halepartiet.Furthermore, it is envisaged that the apparatus according to the invention could be relatively easily modified to also effect the actual removal of fur animals from the animal body, and possibly. For example, the 15 curved pair of fingers 64 can, by means of special clamping jaws at the base, hold the rear portion of the animal body so that the skin can be pulled therefrom by slidable gripping means arranged to be clamped around the fur animal skin, for example at both sides of the tail portion.

Apparatet 2 ifølge opfindelsen anvendes på følgende måde: Højre bagpote af et aflivet pelsdyr fastklemmes med trædepuden opad i venstre holdeklemme 22, venstre bagpote fastklemmes på 25 samme måde i højre holdeklemme 22. Derefter udstrammes bagpartiet af pelsdyret ved forskydning af holdeorganerne 18 bort fra hinanden på føringstangen 12, indtil bagpartiet forløber tilnærmelsesvis vandret mellem holdeklemmerne 22. Den roterende kniv 44 forskydes hen langs oversiden af det hængende, ud-30 spændte bagparti, idet kniven 4 4 evt. styres langs passende styreskinner, der følger forløbet af bagben og bagkrop af pelsdyret, således at der udføres et snit langs bagsiden af bagben og tværover bagkroppen under anus.The apparatus 2 according to the invention is used as follows: The right hind paw of a sacrificed fur animal is clamped with the pedal upwards in the left holding clip 22, the left hind paw is similarly clamped in the right holding clip 22. Thereafter, the rear part of the fur animal is stripped away by displacing the holding means 18 the guide rod 12 until the rear portion extends approximately horizontally between the retaining clips 22. The rotating knife 44 is displaced along the upper side of the hanging, stretched rear portion, the knife 4 is guided along appropriate guide rails which follow the course of the hind leg and hind body of the fur animal, such that a cut is made along the back of the hind leg and transversely the hind body below the anus.

7 DK 168555 B17 DK 168555 B1

Derefter placeres det spadeformede skindløsneorganet 46 i position midt over det opskårne bagparti og føres nedad, således at skindløsnieorganer 46 indføres mellem skindet og dyrekropen ved bugsiden deraf, hvorved også navle og evt. penis fanges og 5 frigøres fra skindet ved hjælp af recessen 68. Herefter fjernes skindløsneorganet 46.Then, the spade-shaped skin release means 46 is positioned in the middle above the cut back portion and is directed downwardly so that skin release means 46 are inserted between the skin and the animal body at the abutment thereof, thereby also providing navel and possibly. the penis is captured and 5 is released from the skin by the recess 68. The skin release means 46 is then removed.

En nedefter åben, skålformet rotorkniv bringes i position midt over pelsdyret og føres nedad for udførelse af et halvcirku-10 lært snit omkring anus og evt. testikler for friskæring af disse dele fra skindet. Ved hjælp af en skå løftecylinder kan dyrekroppen samtidigt løftes lidt opad/udad.A downwardly open, bowl-shaped rotor knife is brought into position in the middle above the fur animal and brought downward to perform a semi-circular cut around the anus and possibly. testicles for cutting these parts from the skin. With the help of an oblique lifting cylinder, the animal body can be lifted slightly upwards / outwards at the same time.

Derefter bringes en kombineret halekniv 54 og haleholder 56 i 15 position midt for det hængende pelsdyr og føres nedad til en postion ud for haleroden. Halen placeres manuelt i haleholderen 56 og en holderulle 58 svinges ind mod oversiden af halen og fastklemmer denne mod halekniven 54. Ved aktivering af cylinderen 60 forskydes halekniv 54 og haleholder 56 opad og 20 skærer herved halen op med et snit langs undersiden af denne.Then, a combined tail knife 54 and tail holder 56 are brought into position in the middle of the hanging fur animal and are directed downward to a position next to the tail root. The tail is positioned manually in the tail holder 56 and a holder roll 58 is pivoted in towards the upper side of the tail and clamps it against the tail knife 54. By activating the cylinder 60, the tail knife 54 and tail holder 56 are displaced upwards, thereby cutting the tail with a cut along the underside thereof.

Nu nedføres apparatdelen 14 over dyret således, at gribefin-gerparene 64 indføres i det opskårne bagparti og klemmes sammen omkring bagbenene tæt ved basis. Derefter føres de krumme 25 gribefingre 64 udad mod hver sin pote og evt. tilbage igen, idet gribefingerne 64 fortsat klemmer omkring hver sit bagben herved frigøres skindet effektivt fra bagbenene.Now the apparatus portion 14 is lowered over the animal such that the gripper finger pairs 64 are inserted into the cut rear portion and clamped around the hind legs close to the base. Then the curved 25 gripping fingers 64 are directed outward towards each paw and possibly. back again, as the gripping fingers 64 continue to clamp around each of its hind legs, effectively releasing the skin from the hind legs.

Bortset fra det indledende åbnesnit ved hjælp af rotorkniven 30 44 er rækkefølgen af de efterfølgende operationer valgfri. Skindløsneorganet 46 kan foroven være forsynet med en krum gribefinger 70, der kan indsvinges omkring halebenet efter opskæring af halen, og som ved ved forskydning opad kan udvirke aftrækning af skindet af den opskårne hale.Except for the initial opening cut by the rotor knife 30 44, the sequence of subsequent operations is optional. The skin release means 46 may be provided at the top with a curved gripping finger 70 which can be pivoted about the tailbone after cutting the tail, and which, when displaced upwards, can cause the skin to be pulled off the cut tail.
