Den foreliggende opfindelse angår en fremgangsmåde til fastholdelse og skrabning af 5 et pelsdyrskind, hvor pelsdyrskindet omfatter en snudeende og en haleende, hvor snudeenden omfatter en mundåbning med en overmund og en undermund, hvor fastholdelse sker til en skrabestok, og hvor skrabning sker på en skrabemaskine omfattende den nævnte skrabestok samt skrabemidler, der er indrettet til at fjerne fedt og kødrester fra den indvendige side af et pelsdyrskind, hvor skrabestokken har en konisk facon 10 med en fri ende, hvor den frie ende udgør den smalleste/tyndeste del af den koniske skrabestok, hvor skrabestokken har en udstrækning fra den nævnte frie ende, med en eller flere flader på periferien, hvor den eller disse flader er indrettet for anlæg af pelssiden på et pelsdyrskind, hvor fremgangsmåden omfatter følgende trin: - at et pelsdyrskind arrangeres på skrabestokken, 15 - at snudeenden på pelsdyrskindet fastholdes ved skrabestokkens frie ende med dertil indrettede første fastholdemidler.The present invention relates to a method of holding and scraping a fur animal skin, wherein the fur animal skin comprises a snout end and a tail end, the snout end comprising a mouth opening with an upper mouth and a lower mouth, where retention is made to a scraper and where scraping is done on a scraper machine. comprising said scraper as well as scraping means adapted to remove fat and meat residue from the inside of a fur animal skin, said scraper having a tapered shape 10 with a free end, the free end forming the narrowest / thinnest part of the tapered scraper wherein the scraper has an extension from said free end, with one or more surfaces on the periphery, wherein said scraper (s) is arranged for laying the fur side on a fur animal, the method comprising the steps of: - arranging a fur animal skin on the scraper; - the snout end of the fur animal skin is retained at the free end of the scraper with its fittings earthing fasteners.

Den foreliggende opfindelse angår endvidere et apparat til fastholdelse og skrabning af et pelsdyrskind, hvor pelsdyrskindet omfatter en snudeende og en haleende, hvor snu-20 deenden omfatter en mundåbning med en overmund og en undermund, hvor apparatet, også kaldet en skrabemaskine, er indrettet til at fjerne fedt og kødrester fra den indvendige side af et pelsdyrskind, hvor apparatet omfatter en skrabestok med en konisk facon og med en fri ende, hvor den frie ende udgør den smalleste/tyndeste del af den koniske skrabestok, hvor skrabestokken har en udstrækning fra den nævnte frie ende, 25 med en eller flere flader på periferien, hvor den eller disse flader er indrettet for anlæg af pelssiden på et pelsdyrskind, hvor apparatet omfatter første fastholdemidler til fastholdelse af snudeenden på pelsdyrskindet ved skrabestokkens frie ende.The present invention further relates to an apparatus for holding and scraping a fur animal skin, wherein the fur animal skin comprises a muzzle end and a tail end, the muzzle end comprising a mouth opening with an upper mouth and a lower mouth, wherein the apparatus, also called a scraper, is adapted to removing fat and meat residue from the inside of a fur animal skin, wherein the apparatus comprises a tapered scraper with a free end, the free end forming the narrowest / thinnest portion of the tapered scraper, the scraper extending from the said free end, 25 having one or more surfaces on the periphery, wherein said surface (s) is arranged for attaching the fur side to a fur animal skin, the apparatus comprising first retaining means for holding the snout end to the fur animal skin at the free end of the scraping stick.

Opfindelsens baggrund I forbindelse med skrabning af pelsdyrskind, herunder særligt i forbindelse med skrab-30 ning af minkskind efter flåning, er det almindeligt, at skindet anbringes med pelssiden ind imod overfladen på en skrabestok og således med lædersiden ud af. Skrabestokken 2 DK 177545 B1 kaldes i daglig tale også, og mere enkelt, for en stok. En sådan stok har typisk enten et cirkulært eller et rektangulært tværsnit og har ydermere typisk en overordnet konisk facon, således at hovedenden på skindet anbringes ved den smalle/tynde ende på stokken, mens resten af skindet strækker sig på langs af stokken mod dennes tykke-5 re/bredere ende. Således støttes skindet optimalt og en mere optimal skrabning kan opnås.BACKGROUND OF THE INVENTION In the case of scraping fur skins, especially in connection with scraping mink fur after peeling, it is common for the skin to be placed with the fur side towards the surface of a scraping stick and thus with the leather side out. Scratch stick 2 DK 177545 B1 is also called, and more simply, for a cane in daily speech. Such a stick typically has either a circular or rectangular cross-section and furthermore typically has an overall tapered shape, such that the head end of the skin is positioned at the narrow / thin end of the stick, while the rest of the skin extends longitudinally of the stick toward its thick. 5 re / wider end. Thus, the skin is optimally supported and a more optimal scraping can be achieved.

Skrabeprocessen har til formål at fjerne fedt og rester af kød fra skindets indvendige side, og skrabestokken bevæges under skrabningen relativt i forhold til en eller flere 10 skraberuller, der dog typisk er arrangeret sætvis ved stokkens sider. På en skrabema-skine med en rektangulær skrabestok er der typisk arrangeret mindst en skraberulle ved hver af stokkens fire sider. Disse skraberuller kan med fordel være arrangeret således, at to sideruller, én ved hver side, styres på en ensartet måde og at en overrulle og en underrulle styres mere eller mindre ensartet som funktion af stokkens relative 15 placering i forhold til den respektive skraberulle.The scraping process aims to remove grease and leftover meat from the inside of the skin, and the scraping rod is moved during scraping relative to one or more 10 scraper rolls, however, typically arranged setwise at the sides of the stick. Typically, at least one scraper roll is arranged on each of the four sides of the log on a scraper grinding machine with a rectangular scraper. These scraper rolls may advantageously be arranged such that two side rollers, one at each side, are controlled in a uniform manner and that a roll and a sub roll are controlled more or less uniformly as a function of the relative position of the log relative to the respective scraper roll.

På siderne af skindet kan der være visse udfordringer med at foretage en god skrabning i det område, som mere eller mindre dækkes af forbenene på skindet, mens der ved overrullen kan være udfordringer med nakkeregionen på skindet, hvor der ofte kan 20 være behov for en mere grundig skrabning, mens skrabningen på undersiden af skindet, svarende til bugen på skindet, ikke volder specielt store problemer eller udfordringer.On the sides of the fur, there may be some challenges in making a good scraping in the area that is more or less covered by the forelegs of the fur, while there may be challenges with the neck region on the fur, where there may often be a need for a scraping. more thorough scraping, while the scraping on the underside of the skin, similar to the belly of the skin, does not pose particularly great problems or challenges.

Det er tidligere indset, at det kan være fordelagtigt at indrette skrabestokken med mid-25 ler for fastholdelse af pelsdyrskindets hovedende ved stokkens tyndeste ende. En sådan fastholdeanordning kan være udført således, at fastholdelsen sker automatisk i forbindelse med aktivering af maskinen og har den fordel, at der uden større arbejdsbyrde for apparatoperatøren, foretages en fastholdelse af skindets hovedende på stokken, som giver større sikkerhed for, at pelsdyrskindet forbliver på stokken under be-30 handlingen med skrabemaskinen. Såfremt at der ikke holdes fast i skindet ved hovedenden kan skraberulleme i visse tilfælde trække skindet længere ind på den koniske stok, hvorved det kan beskadiges og i bedste fald alene føre til en ringere eller mangelfuld skrabning. Eksempelvis kendes der en løsning, hvor to paler ved stokkens tynde- 3 DK 177545 B1 ste ende stikkes gennem pelsdyrskindet ved snude/øje-området for at danne modhold mod, at pelsdyrskindet under behandlingen bliver skubbet til en uhensigtsmæssig position på stokken, hvilket dog betyder høje kvalitetskrav til pelsdyrskindets styrke i snude/øje-området. Samtidig kræver denne løsning en del nøjagtighed ved montage af 5 skindet på stokken, hvilket er besværligt, da de to paler skal føres ind i huller i skindet ved snude/øje-området.It has previously been recognized that it may be advantageous to arrange the scraper with means for retaining the head end of the fur animal at the thinnest end of the stick. Such a restraint device may be designed such that the restraint is performed automatically in connection with the activation of the machine and has the advantage that without major workload for the apparatus operator, the head end of the skin is held on the stick, which gives greater assurance that the fur animal skin remains on the log during the treatment with the scraper. If the skin is not held at the head end, the scraper rollers can in some cases extend the skin further onto the tapered stick, whereby it can be damaged and, at best, only lead to an inferior or defective scraping. For example, a solution is known where two piles at the end of the stick are inserted through the fur animal skin at the snout / eye area to counteract that during the treatment the fur animal skin is pushed to an inappropriate position on the stick, which means high quality requirements for the fur skin strength in the muzzle / eye area. At the same time, this solution requires some accuracy in mounting the 5 skins on the stick, which is difficult as the two piles have to be inserted into holes in the skins at the muzzle / eye area.

Fra DK 2007 00067 U3 kendes en anden løsning, hvor der indvendigt i stokken er arrangeret en længdeforskydelig stang med en endeklods, hvor snuden på skindet fik-10 seres mellem denne endeklods og selve stokkens ende.From DK 2007 00067 U3 another solution is known in which a longitudinally displaceable rod with an end block is arranged inside the stick, whereby the muzzle of the skin is fixed between this end block and the end of the stick itself.

Ligeledes kendes en løsning, der er mere enkel, hurtig og sikker sammenlignet med løsningen med de to paler, fra DK 2010 00036 U3, hvor snuden klemmes mod stokkens ende med en bevægelig krog. Denne løsning virker kort fortalt ved, at der i stok-15 ken er indbygget en mekanisme til betjening af den bevægelige krog, således at den kan bevæges fra en åben position og til en lukket position og samtidig fra en udskudt position til en tilbagetrukket position.Also known is a solution that is simpler, faster and more secure compared to the solution with the two pallets, from DK 2010 00036 U3, where the muzzle is clamped to the end of the stick with a movable hook. In short, this solution works by incorporating in the stick a mechanism for operating the movable hook so that it can be moved from an open position to a closed position and at the same time from an extended position to a retracted position.

I den udskudte og lukkede position kan skindet anbringes i det mellemrum, der dannes 20 mellem selve krogen og stokkens spids, og samtidigt kan skindet let trækkes ind over stokken og krogen, uden at krogen griber fat i skindet og besværliggør dette, hvilket er meget vigtigt, da skrabeprocessen skal foretages så hurtigt som muligt for at opnå en så stor produktion som muligt. Når så skindet er anbragt på stokken, så føres krogen fra den udskudte position til den tilbagetrukne position, mens den holdes i den lukkede 25 position, hvorved skindet fikseres ved hovedenden. Herefter udføres skrabningen af skindet, og efter skrabning frigøres skindet ved, at krogen føres til den åbne position samtidig med, at den føres til den udskudte position, hvorved skindet frigøres optimalt fra stokkens ende, hvilket tillader skindet at blive trukket af stokken til videre behandling. Alternativt kan skindet vendes således, at pelssiden vender udad, inden at krogen 30 frigør sit tag i skindet.In the extended and closed position, the skin can be placed in the space formed between the hook itself and the tip of the stick, and at the same time the skin can be easily pulled over the stick and the hook without the hook gripping the skin and making this difficult, which is very important as the scraping process must be carried out as quickly as possible in order to achieve the largest possible production. When the skin is placed on the stick, the hook is moved from the extended position to the retracted position while being held in the closed position, thereby fixing the skin at the head end. Next, the scraping of the skin is performed and after scraping the skin is released by moving the hook to the open position while moving it to the extended position, thus releasing the skin optimally from the end of the stick, allowing the skin to be pulled off the stick for further processing. . Alternatively, the fur may be turned so that the fur side faces outwardly before the hook 30 releases its roof in the fur.

Bevægelsen af de elementer, der bevirker, at krogen kan flyttes mellem en åben og lukket position og mellem en udskudt og en tilbagetrukket position, kan omfatte et 4 DK 177545 B1 antal aktuatorer og en eller flere stangforbindelser, der er arrangeret indvendigt i skra-bestokken. Hele bevægelsen af et sådant arrangement kan uden videre styres via skra-bemaskinens styringsenhed, der i forvejen styrer en mængde forskellige parametre på skrabemaskinen. Et eksempel herpå er angivet i DK 2010 00036 U3.The movement of the elements which allows the hook to be moved between an open and closed position and between a extended and retracted position may comprise a number of actuators and one or more rod connections arranged internally in the screw rod . The entire movement of such an arrangement can easily be controlled via the scraper control unit, which already controls a variety of parameters on the scraper. An example of this is given in DK 2010 00036 U3.

Det har vist sig, at fastholdelsen af hovedet er aldeles nødvendigt, og at der derudover også er tilfælde, hvor den kendte fastholdelse af skindet ikke er tilstrækkeligt for at undgå at beskadige skindet under skrabning. Det er særligt i forbindelse med skrab-ning af store minkskind, men også ved skrabning af mindre skind, at der kan være 10 problemer med, at den eller de skraberuller, der kører på undersiden af skindet, kan få fat i munden - så at sige i underlæben eller undermunden på skindet, og at dette kan medføre, at skindet rives i stykker, idet der foretages et uhensigtsmæssigt stort træk i underlæben/undermunden, hvorved ’’mundvigene” rives, og skindet beskadiges.It has been found that the retention of the head is absolutely necessary and that in addition there are also cases where the known retention of the skin is not sufficient to avoid damaging the skin during scraping. It is especially in the case of scraping large mink skins, but also in the scraping of smaller skins, that there may be 10 problems that the scraper roller (s) running on the underside of the skin can get to the mouth - so that say in the lower lip or lower mouth of the skin, and that this can cause the skin to tear, making an unduly large pull in the lower lip / lower mouth, thereby "tearing" the mouths and damaging the skin.

15 Ingen af de kendte skrabemaskiner angiver en løsning på dette tekniske problem. Opfindelsens formål15 None of the known scrapers indicate a solution to this technical problem. The object of the invention

Det er formålet med opfindelsen at angive en løsning på det ovenfor nævnte problem med, at en eller flere skraberuller kan få fat i underlæben/undermunden, eller udfører et for stort træk i underlæben/undermunden, under skrabning af lædersiden på et pels-20 dyrskind, således at skindet skades.SUMMARY OF THE INVENTION It is an object of the invention to provide a solution to the above-mentioned problem in that one or more scraper rolls can grab the lower lip / lower mouth, or perform an excessive pull in the lower lip / lower mouth, while scraping the leather side on a fur animal skin. so that the skin is damaged.

Beskrivelse af opfindelsenDescription of the Invention

Opfindelsen angår som indledningsvist angivet en fremgangsmåde til fastholdelse og skrabning af et pelsdyrskind, hvor pelsdyrskindet omfatter en snudeende og en haleende, hvor snudeenden omfatter en mundåbning med en overmund og en undermund, 25 hvor fastholdelse sker til en skrabestok, og hvor skrabning sker på en skrabemaskine omfattende den nævnte skrabestok samt skrabemidler, der er indrettet til at fjerne fedt og kødrester fra den indvendige side af et pelsdyrskind, hvor skrabestokken har en konisk facon med en fri ende, hvor den frie ende udgør den smalleste/tyndeste del af den koniske skrabestok, hvor skrabestokken har en udstrækning fra den nævnte frie 30 ende, med en eller flere flader på periferien, hvor den eller disse flader er indrettet for anlæg af pelssiden på et pelsdyrskind, hvor fremgangsmåden omfatter følgende trin: - at et pelsdyrskind arrangeres på skrabestokken, 5 DK 177545 B1 - at snudeenden på pelsdyrskindet fastholdes ved skrabestokkens frie ende med dertil indrettede første fastholdemidler.The invention relates, as initially indicated, to a method of holding and scraping a fur animal skin, wherein the fur animal skin comprises a snout end and a tail end, the snout end comprising a mouth opening with an upper mouth and a lower mouth, where retention is made to a scraping stick and where scraping is done on a scraper comprising said scraper as well as scraping means adapted to remove fat and meat residue from the inside of a fur animal, the scraper having a tapered shape with a free end, the free end forming the narrowest / thinnest part of the tapered scraper wherein the scraper has an extension from said free end, with one or more surfaces on the periphery, wherein said scraper (s) is arranged for laying the fur side on a fur animal, the method comprising the steps of: - arranging a fur animal skin on the scraper; 5 DK 177545 B1 - the snout end of the fur animal skin is held at the free end of the scraper e with the first fasteners arranged therefor.

Det nye ved en fremgangsmåde ifølge opfindelsen er, at fremgangsmåden yderligere 5 omfatter følgende trin: - at et pelsdyrskind, ved snudeenden, fastholdes mod skrabestokken, ved skrabestokkens frie ende med yderligere fastholdemidler, ved det område på pelsdyrskindet, der udgør undermunden, hvorved undermunden fastholdes mod stokkens frie ende under skrabning.The new feature of a method according to the invention is that the method further comprises the following steps: - a fur animal skin, at the snout end, is held against the scraper, at the free end of the scraper with additional retaining means, at the area of the fur animal skin constituting the lower mouth, whereby the lower mouth is retained towards the free end of the stick during scraping.

Netop det, at undermunden fastholdes mod stokken bevirker, at mundåbningen holdes i en lukket position, hvilket medfører dels en markant bedre skrabning af området under hovedet på pelsdyrskindet og dels en meget mindre risiko for, at skindet beskadiges under påvirkning af den eller de skraberuller, som er indrettet til at skrabe dette 15 område på skindet. Ved visse typer af minkskind, og særligt ved store minkskind, er netop undermundens størrelse en udfordring, idet undermunden også er større og i princippet udgør en flap, som hænger mere eller mindre lodret ned fra skindet, når dette er arrangeret på en skrabestok. Når så skrabestokken bevæges relativt i forhold til skraberulleme, eksempelvis ved at en konisk skrabestok med et rektangulært tværsnit 20 føres ind imellem et antal skraberuller, så udøves der et ret stort træk i denne flap, altså undermunden, hvilket kan forårsage, at skindet rives og dermed mister værdi. Samtidig kan det også være nødvendigt at foretage en efterfølgende skrabning af undersiden af hovedet og halsen på pelsdyrskindet.Precisely that the lower mouth is held against the cane causes the mouth opening to be held in a closed position, which results in a significantly better scraping of the area under the head of the fur animal and partly a much less risk of damage to the skin under the influence of the scraper roll (s). which is arranged to scrape this area on the skin. For certain types of mink skins, and especially for large mink skins, precisely the size of the lower mouth is a challenge, since the lower mouth is also larger and in principle constitutes a flap which hangs more or less vertically from the skin when arranged on a scraping stick. Then, when the scraper is moved relative to the scraper rolls, for example by inserting a tapered scraper with a rectangular cross-section 20 between a number of scraper rolls, a fairly large pull is exerted in this flap, i.e. the lower mouth, which can cause the skin to tear and thus losing value. At the same time, it may also be necessary to make a subsequent scraping of the underside of the head and neck of the fur animal skin.

25 Med en fremgangsmåde ifølge opfindelsen opnås der den fordel, at skraberulleme ikke kan få fat i undermunden, idet den som nævnt fastholdes op mod stokken. Der er således tale om, at munden holdes lukket på skindet, og at skrabningen kan ske uden bekymring for, om skindet rives i mundvigene. Herved opnås såvel en bedre skrabning med dertilhørende højere kvalitet på skindet som en stærkt reduceret risiko for at øde-30 lægge skind under skrabeprocessen. Ikke alene undgås det at beskadige skind under skrabning, men de skind, der skrabes ifølge denne fremgangsmåde, har også en højere kvalitet, da skrabningen i området om munden og under halsen forbedres betragteligt.With a method according to the invention, the advantage is obtained that the scraper rolls cannot reach the lower mouth, as mentioned, it is held up against the stick. This means that the mouth is kept closed on the skin and that the scraping can be done without worrying about the skin being torn in the mouth folds. This results in better scraping with the associated higher quality of the skin as well as a greatly reduced risk of destroying skins during the scraping process. Not only does it prevent damage to the skins during scraping, but the skins scraped according to this method also have a higher quality as the scraping in the area of the mouth and under the neck is greatly improved.

Med en fremgangsmåde ifølge opfindelsen opnås der således mulighed for at udføre skrabning af pelsdyrskindet fra snudeenden og imod haleenden, hvor i det mindste skrabning af pelsdyrskindets underside, svarende til hagen og halsen, starter ved og sker fra den yderste del af snudeområdet. Med den kendte teknik har man ofte startet 5 med en mere skånsom skrabning på den forreste del af pelsdyrskindet, for netop at skåne skindet for en mulig beskadigelse, men med et ringere skraberesultat til følge.Thus, with a method according to the invention, it is possible to carry out scraping the fur animal skin from the snout end and towards the tail end, where at least scraping the underside of the fur animal skin, corresponding to the chin and neck, starts at and occurs from the outermost part of the snout area. With the prior art, 5 have often started with a more gentle scraping on the front part of the fur animal skin, just to spare the skin for possible damage, but with a poorer scraping result.

Når skraberesultatet er ringere, er kvaliteten og dermed også prisen på skindet ringere.When the scraping result is inferior, the quality and thus the price of the fur is inferior.

Der er derfor en forholdsvis kontant fordel ved at kunne foretage en bedre skrabning af særligt det område på minkskindet, der kan betegnes som snudeenden og særligt under 10 hagen og på halsen.Therefore, there is a relatively cash advantage of being able to make a better scraping of especially the area of the mink skin, which can be termed the snout end and especially under the chin and neck.

Med begreberne snudeenden og snudeområdet menes den forreste del af et pelsdyrskind og i særdeleshed den del af pelsdyrskindet, der omfatter snuden og resten af hovedet, herunder hagen, halsen og til dels den forreste del af bugen.By the terms snout end and snout area is meant the front part of a fur animal skin and in particular the part of the fur animal skin comprising the snout and the rest of the head, including the chin, neck and, in part, the front part of the abdomen.

En fremgangsmåde ifølge opfindelsen kan med fordel yderligere omfatte følgende trin: - manuel placering af undermunden på pelsdyrskindet i anlæg mod skrabestokken ved dennes frie ende, idet undermunden presses mod en eller flere holdeanordninger, eksempelvis sugeåbninger i skrabestokken for fastholdelse i denne position forud for 20 mekanisk fastholdelse ved aktivering af de yderligere fastholdemidler. Herved fastholdes den ellers nedad hængende undermund i en position under stokken. Denne fastholdelse er dog slet ikke tilstrækkelig under skrabningen og tjener alene det formål at sikre, at skindet er i den rette position forud for aktivering af mekaniske fastholdemidler. Ved at anvende sugeåbninger eller lignende øges sikkerheden betragteligt, idet en 25 bruger herved ikke risikerer at få sine fingre i klemme i fastholdemidlerne under aktivering af disse. Med fremgangsmåden kan pelsdyrskindet arrangeres på en skrabestok og rettes ind manuelt således, at det er i den helt rigtige position forud for, at de respektive mekaniske fastholdemidler aktiveres. Med hensyn til de kendte fastholdemidler, der anvendes ved snuden på pelsdyrskindet, er dette relativt let klaret, idet skindet 30 let lader sig placere som ønsket, men undermunden kan i visse tilfælde have behov for at blive fastholdt mod stokken forud for endelig fastholdelse, hvilket særligt skyldes, at munden typisk er placeret på undersiden af stokken, hvorfor undermunden selvsagt har en tendens til at hænge nedad.A method according to the invention can advantageously further comprise the following steps: - manual placement of the lower mouth of the fur animal abutment against the scraper at its free end, the lower mouth being pressed against one or more holding devices, for example suction openings in the scraper for holding in this position prior to mechanical retention by activating the additional retention means. In this way, the otherwise downwardly sloping lower mouth is held in a position below the cane. However, this retention is not at all sufficient during the scraping and serves only the purpose of ensuring that the skin is in the correct position prior to activation of mechanical restraints. By using suction openings or the like, the security is greatly increased, as a user does not risk getting his fingers caught in the restraints during activation thereof. With the method, the fur animal skins can be arranged on a scraping stick and adjusted manually so that it is in the correct position prior to activating the respective mechanical restraints. With respect to the known fasteners used in the fur of the fur animal skin, this is relatively easily clarified, with the skin 30 being easily positioned as desired, but in some cases the lower mouth may need to be held against the cane prior to final restraint, which This is mainly because the mouth is typically located on the underside of the cane, which is why the lower mouth naturally tends to hang downwards.

Endelige kan en fremgangsmåde ifølge opfindelsen omfatte, at der efter endt skrab-ning yderligere udføres følgende trin: - frigørelse af det skrabede pelsdyrskindet ved de-aktivering af såvel de første fasthol-5 demidler, der fastholder snudeenden til skrabestokken, som de yderligere fastholdemidler, der holder undermunden mod skrabestokken, hvorved skindet er fri til at kunne tages af skrabestokken. Frigørelsen af skindet fra skrabestokken kan ske umiddelbart efter, at skrabningen er fuldført, således at skindet trækkes af stokken med lædersiden udad. Det er dog også muligt at trække pelsdyrskindet af skrabestokken, alt 10 imens det stadig fastholdes i snudeenden, hvorved der sker en vending af pelsdyrskindet således, at pelssiden vender udad og lædersiden indad. Alt afhængigt af, hvordan en pelsdyravler har stillet sin skrabeproces an, kan begge metoder være at foretrække. Såfremt at skrabningen er udført så godt, at skindet er helt fri for fedt og derfor ikke behøver påføres savsmuld, så kan det med fordel vendes direkte i forbindelse med, at 15 det tages af skrabestokken. Skal lædersiden på pelsdyrskindet derimod påføres savsmuld for at optage fedt og fugt, så er det nødvendigt, at skindet ikke vendes, når det tages af skrabestokken.Finally, a method according to the invention may comprise the following steps being further completed after scraping: - releasing the scraped fur animal skin by deactivating both the first retaining means holding the end of the scraping rod and the additional retaining means, which holds the lower mouth against the scraper, whereby the skin is free to be removed from the scraper. Release of the skin from the scraper can be done immediately after scraping is completed, so that the skin is pulled off the stick with the leather side outward. However, it is also possible to pull the fur animal skin off the scraper, all while retaining it at the snout end, thereby reversing the fur animal skin so that the fur side faces outward and the leather side inward. Depending on how a furry farmer has adjusted his scraping process, both methods may be preferable. If the scraping is done so well that the skin is completely free of grease and therefore does not need to be applied to sawdust, then it can advantageously be reversed directly in connection with the removal of the scraping stick. However, if the leather side of the fur animal skin is applied to sawdust to absorb fat and moisture, it is necessary that the skin is not turned when it is taken off the scraper.

Opfindelsen angår endvidere og som nævnt indledningsvist også et apparat til fasthol-20 delse og skrabning af et pelsdyrskind, hvor pelsdyrskindet omfatter en snudeende og en haleende, hvor snudeenden omfatter en mundåbning med en overmund og en undermund, hvor apparatet, også kaldet en skrabemaskine, er indrettet til at fjerne fedt og kødrester fra den indvendige side af et pelsdyrskind, hvor apparatet omfatter en skra-bestok med en konisk facon og med en fri ende, hvor den frie ende udgør den smalle-25 ste/tyndeste del af den koniske skrabestok, hvor skrabestokken har en udstrækning fra den nævnte frie ende, med en eller flere flader på periferien, hvor den eller disse flader er indrettet for anlæg af pelssiden på et pelsdyrskind, hvor apparatet omfatter første fastholdemidler til fastholdelse af snudeenden på pelsdyrskindet ved skrabestokkens frie ende.The invention further relates, and as mentioned initially, to an apparatus for holding and scraping a fur animal skin, wherein the fur animal skin comprises a snout end and a tail end, wherein the snout end comprises a mouth opening with an upper mouth and a lower mouth, the apparatus also called a scraper machine, is adapted to remove fat and meat residue from the inside of a fur animal skin, the apparatus comprising a tapered scraper with a conical shape and with a free end, the free end forming the narrowest / thinnest part of the tapered scraper wherein the scraper extends from said free end, with one or more surfaces on the periphery, wherein said scraper (s) is arranged for abutment of the fur side of a fur animal skin, the apparatus comprising first retaining means for holding the snout end to the fur animal skin at the free end of the scab .

Et sådant apparat ifølge opfindelsen kan med fordel omfatte yderligere fastholdemidler til at fastholde et pelsdyrskind, ved snudeenden ved det område på pelsdyrskindet, der udgør undermunden, hvor disse yderligere fastholdemidler omfatter en krogdel, der i 30 8 DK 177545 B1 det mindste er bevægelig mellem en første åben position og en anden lukket position, og hvor krogdelen er arrangeret ved skrabestokkens frie ende. Hermed kan undermunden holdes i position og i anlæg med skrabestokken under skrabning, hvorved en bedre skrabning opnås, og samtidig reduceres - eller fjernes - risikoen for, at skindet ska-5 des i området ved undermunden og mundvigene, hvor det ellers let kunne rives.Such an apparatus according to the invention may advantageously comprise additional retaining means for retaining a fur animal skin, at the snout end at the area of the fur animal skin constituting the lower mouth, where these additional retaining means comprise a hook part which is at least movable between a first open position and a second closed position, where the hook portion is arranged at the free end of the scraper. This allows the lower mouth to be held in position and in abutment with the scraper during scraping, thereby obtaining a better scraping, while at the same time reducing - or removing - the risk of the skin being damaged in the area of the lower mouth and mouth folds, where it could otherwise easily be torn.

I en variant af et apparat ifølge opfindelsen kan den nævnte krogdel betjenes mellem i det mindste den nævnte første åbne og den nævnte anden lukkede position, ved påvirkning af en mekanisk forbindelse, hvor den nævnte mekaniske forbindelse er ind-10 bygget i skrabestokken. Ved at indbygge den mekaniske forbindelse i skrabestokken således, at selve krogdelen er fri ved skrabestokkens frie ende til at bevæge sig som omtalt, og hvor de mekaniske eller elektriske dele, der medfører bevægelsen af krogdelen, er arrangeret ved eller på skrabestokken, i en position, der ikke kommer i kontakt med hverken skraberuller eller pelsdyrskind under en skrabeproces, opnås der den 15 fordel at disse mekaniske eller elektriske dele er godt beskyttet mod vand og fedt. Netop vand og/eller fedt kan i forbindelse med skrabning af pelsdyrskind være en udfordring, idet det er aldeles uønsket at få eksempelvis fedt på hårsiden af skindet, men samtidig kan det også være en udfordring at undgå, at fedt trænger ind forskellige uønskede steder på hele apparatet. En foretrukken position for de midler, der anvendes til 20 at påvirke såvel de kendte fastholdemidler, ved snudeenden og fastholdemidlerne ved undermunden ifølge opfindelsen, er ved den ende af skrabestokken, som er fikseret til selve apparatet ved dettes chassis eller lignende.In a variant of an apparatus according to the invention, said hook portion can be operated between at least said first open and said second closed position, by actuating a mechanical connection wherein said mechanical connection is built into the scraper. By incorporating the mechanical connection in the scraper so that the hook part itself is free at the free end of the scraper to move as mentioned, and where the mechanical or electrical parts which cause the movement of the hook member are arranged at or on the scraper, in a position that do not come into contact with either scraper rolls or fur animals during a scraping process, the advantage is obtained that these mechanical or electrical parts are well protected from water and grease. Exactly water and / or fat can be a challenge in the scraping of fur animals, as it is completely undesirable to get, for example, grease on the hair side of the skin, but at the same time it can also be a challenge to prevent grease from entering various undesirable places in the whole apparatus. A preferred position for the means used to actuate both the known retaining means at the snout end and the retaining means of the lower mouth of the invention is at the end of the scraper fixed to the apparatus itself by its chassis or the like.

I en foretrukken udførelse kan et apparat ifølge opfindelsen være indrettet således, at 25 den nævnte krogdel på de yderligere fastholdemidler er samvirkende med de første fastholdemidler for fastholdelse af pelsdyrskindets snudeende til stokkens frie ende.In a preferred embodiment, an apparatus according to the invention may be arranged such that said hook portion of the additional retaining means cooperates with the first retaining means for holding the fur end of the fur of the fur animal to the free end of the stick.

Der kan herved være mulighed for at anvende den eller de samme bevægelsesgiver til såvel den ene som den anden form for fastholdemidler. Der kan eksempelvis være tale om hydrauliske, elektriske eller pneumatiske aktuatorer, typisk lineære aktuatorer, der 30 via en eller flere stangforbindelser påvirker de nævnte fastholdemidler til bevægelse mellem de mulige positioner. Der kan eksempelvis anvendes et system svarende til det, der er beskrevet i DK 2010 00036 U3.Hereby it may be possible to use the same or the same motion sensor for one or the other type of retaining means. These may be, for example, hydraulic, electrical or pneumatic actuators, typically linear actuators, which, via one or more rod connections, influence said retaining means for movement between the possible positions. For example, a system similar to that described in DK 2010 00036 U3 may be used.

Et apparat ifølge opfindelsen kan også være udført således, at den nævnte krogdel på de yderligere fastholdemidler og de første fastholdemidler for fastholdelse af pelsdyrskindets snudeende til stokkens frie ende er individuelt bevægelige. Herved opnås der mulighed for en fuldstændig individuel styring af de to sæt af fastholdemidler. Eksem -5 pelvis kan først det ene sæt af fastholdemidler aktiveres og fastholde snuden, hvorefter undermunden bringes i position forud for aktivering af de fastholdemidler, der er indrettet til fastholdelse af denne.An apparatus according to the invention may also be designed such that said hook portion of the additional retaining means and the first retaining means for holding the fur end of the fur of the fur animal to the free end of the cane are individually movable. This allows for a complete individual control of the two sets of retaining means. For example, firstly, one set of retaining means can be activated and retained by the snout, after which the lower mouth is brought into position prior to actuation of the retaining means arranged to retain it.

I en særlig variant af et apparat ifølge opfindelsen kan skrabestokken omfatte en eller 10 flere sugeåbninger ved skrabestokkens frie ende, hvor en eller flere sådanne sugeåbninger er forbundet med et apparat indrettet til at skabe et sug, hvor sug i en eller flere sugeåbninger bevirker, at undermunden på et pelsdyrskind kan placeres manuelt og holdes i position mod skrabestokken forud for mekanisk fastholdelse med de nævnte fastholdemidler. Dette medfører, at skindet kan placeres i den helt rigtige position for-15 ud for aktivering af fastholdemidleme, hvilket øger sikkerheden for den person, der betjener apparatet, idet de mekaniske fastholdemidler eksempelvis ikke kan aktiveres, før brugeren har begge sine hænder på et betjeningspanel, hvormed apparatet aktiveres.In a particular variant of an apparatus according to the invention, the scraper can comprise one or more suction openings at the free end of the scraper, where one or more such suction openings are connected to an apparatus adapted to create a suction, wherein suction in one or more suction openings causes the lower mouth of a fur animal skin may be positioned manually and held in position against the scraper prior to mechanical retention with said retaining means. This means that the skin can be placed in the correct position in front of activating the retaining means, which increases the safety of the person operating the apparatus, for example, the mechanical retaining means cannot be activated until the user has both hands on a control panel. , by which the device is activated.

Detaljeret beskrivelse af opfindelsenDetailed description of the invention

Fig. 1 viser skematisk en del af en skrabemaskine med en skrabestok 1 og med side-skraberuller 2 og med en overskraberulle 3 samt med en underskraberulle 4. Disse 20 skraberuller 2, 3, 4 er arrangeret ved skrabestokkens fire sider. Som det ses i fig. 1 har skrabestokken 1 en fri ende 5, mens den anden ende er fikseret til selve skrabemaski-nens chassis eller lignende, hvilket dog ikke ses i figuren.FIG. 1 schematically shows a part of a scraper with a scraper 1 and with side scraper rolls 2 and with a scraper roll 3 and with a scraper roll 4. These 20 scraper rolls 2, 3, 4 are arranged at the four sides of the scraper. As seen in FIG. 1, the scraper stick 1 has a free end 5, while the other end is fixed to the chassis or the like of the scraping machine itself, which, however, is not seen in the figure.

I fig. 2 ses den yderste del 6 af en skrabestok 1 med et første sæt af fastholdemidler 7, 25 for fastholdelse af snudeenden på et pelsdyrskind, og yderligere ses et andet sæt af fastholdemidler 8, for fastholdelse af undermunden på et pelsdyrskind, hvor begge sæt af fastholdemidler 7, 8 er vist i monteringsposition. Monteringsposition er den position, hvori fastholdemidleme 7, 8 er placeret under montering af et pelsdyrskind på skrabestokken 1. Det er med fastholdemidleme 7, 8 i denne position let at trække et 30 pelsdyrskind på skrabestokken 1, uden at skindet hænger fast i den yderste del 6.1 den viste variant af opfindelsen ses de første fastholdemidler 7 for snudeenden som en første krog 7, der er arrangeret således, at den vender opad - er hævet - og danner en 11 DK 177545 B1 åbning 9 mellem selve skrabestokken 1 og den første krog 7. Når skindet trækkes på stokken føres den første krog 7 ud gennem mundåbningen i skindet, og snuden på skindet placeret i åbningen 9.In FIG. 2, the outer portion 6 of a scraping stick 1 is shown with a first set of retaining means 7, 25 for retaining the snout end of a fur animal skin, and a second set of retaining means 8 is shown for retaining the lower mouth of a fur animal skin, where both sets of retaining means 7, 8 are shown in mounting position. Mounting position is the position in which the retaining means 7, 8 are positioned during mounting a fur animal skin on the scraper stick 1. With the retaining means 7, 8 in this position, it is easy to pull a fur fur skin on the scraper stick 1 without the fur clinging to the outer part. 6.1. The embodiment of the invention shown, the first retaining means 7 for the end of the snout are regarded as a first hook 7 arranged so that it faces upwards - is raised - and forms an opening 9 between the scraper stick 1 and the first hook 7 When the skin is pulled on the stick, the first hook 7 is extended through the mouth opening of the skin and the muzzle of the skin located in the opening 9.

5 Den første krog 7 er svingbart monteret i forhold til en rørformet stangforbindelse 10, der strækker sig gennem skrabestokken 1, idet krogen 7, ved en frem og tilbage bevægelse af en stang 11, der forløber indvendigt i den rørformede stangforbindelse 10, kan svinges om en omdrejningsakse 12, og således bevæges i forhold til den yderste del 6 på skrabestokken 1, mellem en hævet position og en sænket position som vist i fig. 4.5 The first hook 7 is pivotally mounted relative to a tubular rod connection 10 extending through the scraper stick 1, the hook 7 being pivotally swiveled by a reciprocating movement of a rod 11 extending internally into the tubular rod connection 10. an axis of rotation 12, and thus is moved relative to the outermost portion 6 of the scraper stick 1 between a raised position and a lowered position as shown in FIG. 4th

10 Bevægelsen af den første krog 7 kan således være såvel frem og tilbage som en svingende bevægelse om omdrejningsaksen 12. De forskellige positioner ses i fig. 2, fig. 3 og i fig. 4.Thus, the movement of the first hook 7 can be both forward and backward as well as a pivotal movement about the axis of rotation 12. The different positions can be seen in FIG. 2, FIG. 3 and in FIG. 4th

Under den ovenfor omtalte første krog 7 er der arrangeret yderligere fastholdemidler 8 15 for undermunden på skindet, og disse yderligere fastholdemidler 8 udgøres af en fremadrettet anden krog 8. Denne anden krog 8 er ligeledes arrangeret svingbar, idet den kan svinges om en omdrejningsakse 13, der er fikseret ved den yderste del på skrabestokken 1. Bevægelse af den anden krog 8 sker via en arm 14, der er forbundet til den rørformede stangforbindelse 10, hvor armen 14 kan bevæges om to omdrejningsakser 20 15, således at den anden krog 8 bevæges mellem den i fig. 2 viste fremadrettede posi tion og den i fig. 3 viste bagudrettede position, hvor den anden krog 8 ligger an mod undersiden på den yderste del 6 på skrabestokken 1. Bevægelsen af såvel den første krog 7 som den anden krog 8 sker i denne variant ved en frem og tilbagebevægelse af den rørformede stangforbindelse 10, mens det er den indvendige stang 11, der skal 25 bevæges for at svinge den første krog 7 mellem den hævede og den sænkede position.Under the first hook 7 mentioned above, additional retaining means 8 15 are arranged for the lower mouth of the skin, and these additional retaining means 8 comprise a forward second hook 8. This second hook 8 is also arranged pivotally as it can be pivoted about a axis of rotation 13, which is fixed at the outermost part of the scraper stick 1. Movement of the second hook 8 takes place via an arm 14 which is connected to the tubular rod connection 10, where the arm 14 can be moved about two rotational axes 20 15 so that the second hook 8 is moved. between the one shown in FIG. 2 and the forward position shown in FIG. 3, where the second hook 8 abuts the underside of the outermost portion 6 of the scraper stick 1. The movement of both the first hook 7 and the second hook 8 takes place in this variant by a reciprocating movement of the tubular rod connection 10, while it is the inner bar 11 that must be moved to swing the first hook 7 between the raised and lowered positions.

I fig. 3 ses den yderste del 6 af en skrabestok 1 med to sæt fastholdemidler 7, 8 i fastholdeposition, svarende til den position som fastholder såvel snuden på et pelsdyrskind, men også undermunden mod skrabestokkens yderste del 6. Som det ses i fig. 3, 30 er både den første krog 7 og den anden krog 8 bevæget i forhold til det, der ses i fig. 2, idet åbningen 9 er lukket, mens den anden krog 8 er bagudrettet. Når de respektive fastholdemidler 7, 8 er i denne position, er et skind korrekt monteret på skrabestokken 1, og en skrabning kan udføres. Efter endt skrabning skal pelsdyrskindet frigøres fra 12 DK 177545 B1 skrabestokken 1, og det sker ved, at den rørformede stangforbindelse 10 skubbes i retning mod skrabestokkens yderste del 6, således åbnes den første krog delvist, mens den anden krog 8 åbnes helt. Den første krog 7 åbnes endnu mere ved at trække stangen 11 i modsat retning eller ved blot at holde den fast. Herved bringes den første krog 5 7 i en fremadrettet position som ses her i fig. 4, hvilket medfører en meget let frigørel se af det skrabede pelsdyrskind. Inden at et nyt pelsdyrskind trækkes på skrabestokken 1, positioneres den første krog 7 igen i den position, som er vist i fig. 1, hvilket medfører, at skindet lettere lader sig trække på stokken, idet det ikke hænger fast i eksempelvis den fremadrettede første krog 7.In FIG. 3, the outer portion 6 of a scraping stick 1 is shown with two sets of retaining means 7, 8 in the retaining position, corresponding to the position holding both the muzzle of a fur animal skin, but also the lower mouth to the outermost part of the scraping stick 6. As seen in FIG. 3, 30, both the first hook 7 and the second hook 8 are moved relative to that seen in FIG. 2, the opening 9 being closed while the second hook 8 is rearward facing. When the respective retaining means 7, 8 are in this position, a skin is properly mounted on the scraper stick 1 and a scraping can be performed. After scraping is completed, the fur animal skin must be released from the scraper stick 1, and this is done by pushing the tubular rod connection 10 towards the outer part 6 of the scraper, thus opening the first hook partially while opening the second hook 8 completely. The first hook 7 is opened even more by pulling the rod 11 in the opposite direction or by simply holding it. Hereby the first hook 57 is brought into a forward position as seen here in FIG. 4, which causes a very light release of the scraped fur animal skin. Before pulling a new fur animal skin on the scraper stick 1, the first hook 7 is re-positioned in the position shown in FIG. 1, which makes the skin easier to pull on the stick, since it does not stick to, for example, the forward first hook 7.
