ι 5 Opfindelsen angâr en fremgangsmâde og et apparat til klassificering af k0d, særlig til bestemmelse af han-delsklassen for slagtehalvkroppe af svin, hvor skin-kekonturen og den maksimale skinketykkelse aff01es e-lektrooptisk pâ forud fastsatte steder pà en slagte-10 halvkrop til bestemmelse af de paramétré, der har be-tydning for handelsklassen.The invention relates to a method and apparatus for classifying meat, in particular for determining the trade class for pig carcasses, in which the ham contour and maximum hammer thickness are displayed electro-optically at predetermined locations at a carcass half body for determination. of the parameters that have significance for the trading class.
I henhold til en i Tyskland lovmæssig forordning om handelsklasser af 1.2.1972 skal parterede svine-15 kroppe, som erhvervsmæssigt kommer i handelen, klas-sificeres, hvorved der ud fra objektive og subjektive kendetegn foretages en bed0mmelse til inddeling af parterede kroppe i fem klasser, nemlig klasserne E, I, II, III og IV. I den forbindelse betyder: 20 E: Ekstra med fremragende udformning af aile k0d- bærende kropsdele; I: Perfekt k0dfuld med meget god udformning af 25 aile k0dbærende kropsdele; II: K0dfuld med en god udformning af aile k0dbæ- rende kropsdele eller ligesom handelsklasse I, men med en afvigelse i en k0dbærende kropsdel; 30 III: Mindre k0dfuld med en mellemgod udformning af de k0dbærende kropsdele eller ligesom handelsklasse II, men med en afvigelse i en k0d-bærende kropsdel eller ligesom handelsklasse 2Pursuant to a statutory regulation on trading classes in Germany of 1.2.1972, paired pig-15 bodies which are commercially traded must be classified, thereby making an assessment of divided bodies into five classes based on objective and subjective characteristics , namely classes E, I, II, III and IV. In this context: 20 E: Extra with excellent design of all meat-bearing body parts; I: Perfectly meaty with very good design of 25 aile meat-bearing body parts; II: Meat-packed with a good design of all meat-bearing body parts or like commercial class I, but with a deviation in a meat-bearing body part; 30 III: Less meaty with a medium design of the meat-bearing body parts or like commercial class II, but with a deviation in a meat-bearing body part or like trading class 2

I, men med en afvigelse i to k0dbærende krops-dele, og IV: Aile parterede kroppe, som ikke opfylder nævn- 5 te handelsklassers bestemmelser, samt partere de svinekroppe fra svin, der vantrivedes eller er blevet garnie.I, but with a deviation in two flesh-bearing body parts, and IV: all parted bodies which do not comply with the provisions of the said commercial classes, and partake of the pig carcasses of pigs which have become or have become garnish.
Formâlet med denne fremgangsmâde er at g0re handelen 10 med parterede svinekroppe overskuelig under hensynta-gen til slagteværdien og skabe et objektivt grundlag for betalingen af parterede svinekroppe. Endvidere kan der opnâs en overskuelig notering for parterede svinekroppe, der er inddelt efter slagteværdi og der-15 med er oplysende, og der skabes en gyldig kvalitets-mâlestok for producenten af slagtesvin.The purpose of this approach is to make the trade 10 with pared pig carcasses transparent, taking into account the carcass value and to create an objective basis for the payment of carcassed pig carcasses. Furthermore, a clear listing can be obtained for partitioned pig carcasses, classified according to slaughter value and thereby informative, and a valid quality scale for the slaughter pig producer is created.
De objektive kriterier til bed0mmelse af en parteret svinekrop bestâr i bed0mmelsen af andelen af fedtvæv 20 pâ grundlag af ryggens spæktykkelse under hensyntagen til de parterede svinekroppes vægt, medens de subjek-tive kriterier bestâr i den subjektive bed0mmelse af k0dfylden i de k0dbærende kropsdele, nemlig i skinke, skulder, kotelet med kam samt bug.The objective criteria for assessing a paired pig body consist in the assessment of the proportion of adipose tissue 20 on the basis of the thickness of the spine, taking into account the weight of the paired pig body, while the subjective criteria consist in the subjective assessment of the meat body in the carnivorous body. ham, shoulder, cutlet and comb.
25 I henhold til forordningen om handelsklasser fore-slâs, at der anvendes en mâlelære pâ lænden og der, hvor det sidste ribben befinder sig, for at fastslâ spækkets tykkelse, pâ hvilken mâlelære klassegrænser-30 ne er afmærket.25 According to the Trade Class Regulation, it is proposed to use a gauge on the lumbar and where the last rib is located to determine the thickness of the slit on which the gauge class boundaries 30 are marked.
Medens spækkets tykkelse bâde omkring skinken og om-kring det sidste ribben relativt fejlfrit kan aflæses med dette instrument, g0r den subjektive bed0mmelseWhile the thickness of the crack both around the ham and around the last rib can be read relatively easily with this instrument, the subjective assessment

Imod den forenk-ling, der var tilsigtet inden for handelen med parterede svinekroppe, f0rer dette til en uhyre stor for-10 virring hos producenten og aftageren, sâledes at vær-dien af forordningen om handelsklasser er tvivlsom.3 of the mated pig carcass, which according to the trade classes regulation must be made next to the objective assessment, which subjective assessment determines the type of expression of the meat filling in the 5 meat-bearing body parts, the whole classification questionable, since the assessors subjective opinion may differ significantly depending on the circumstances. Contrary to the simplification that was intended in the trade in carcassed pig carcasses, this leads to an enormous deterioration in the manufacturer and the customer, so that the value of the trade class regulation is questionable.
I US patentskrift nr. 3.979.835 og det hertil svaren-de DE offentligg0relsesskrift nr. 2.512.374 beskrives 15 en fremgangsmâde, hvormed det er muligt at foretage en kvalitetssortering af dyrekroppe og k0dstykker. Kvalitetskriterier er heri anf0rt at være tykkelsen af rygspækket, dyrekroppens længde og vægt, og frem-gangsmâden muligg0r, at kvalitetsbestemmelsen kan fo-20 retages pâ et hvilket som helst forarbejdningstids-punkt (se side 4, f0rste afsnit; side 5, tredie af-snit). Til mâlingen anvendes to hândbetjente værkt0-jer, hvori en længdeændring i et udtrækkeligt kabel omsættes til elektriske impulser, som i en datamat 25 omsættes til et digital signal, som er formâlstjen-ligt.U.S. Patent No. 3,979,835 and the corresponding DE Publication No. 2,512,374 discloses a method by which a quality sorting of animal carcasses and cuts of meat is possible. Quality criteria are stated herein to be the thickness of the backpack, length and weight of the animal body, and the method allows the quality determination to be made at any processing time (see page 4, first paragraph; page 5, third paragraph). cut). For the measurement, two hand-operated tools are used, in which a length change in a retractable cable is converted into electrical pulses, which in a computer 25 are converted into a digital signal which is useful.
Medens det ene værkt0js kabel trækkes ud med hânden og lægges mod k0dstykket pâ samme mâde, som man an-30 vender et metermàl for at bestemme dettes længde, st0des i forbindelse med det andet værkt0j en kniv igennem fedtlaget til bindevævet (skillelaget mellem fedt og k0d), og hermed bliver afstanden mellem fedt-overfladen og bindevævet aflæst ved en mâling af ' '........ 4While the one tool cable is pulled out by hand and laid against the piece of meat in the same way that a meter is used to determine its length, a knife is inserted through the other tool through the fat layer to the connective tissue (the separating layer between fat and meat ), and thus the distance between the fat surface and the connective tissue is read by a measurement of '' ........ 4

Ved udtrækningen henholdsvis sammentrykningen af kablet fremkommer der elektriske analogsignaler, som i en datamat omsættes til digitale signaler og g0res synlige. Udnyttelsen 5 at de opnâede mâleresultater sker sâ ved brug af ta-beller og ud0ves af en operat0r.the length of the pulled cable piece. During the extraction and compression of the cable, respectively, electrical analog signals are generated, which in a computer are converted to digital signals and made visible. The utilization 5 that the obtained measurement results are then made using tables and is performed by an operator.
Den ovenfor beskrevne fremgangsmâde adskiller sig fra den i handelsklasseforordningen foreskrevne frem-10 gangsmâde ved, at de mekanisk tilvejebragte længde-mâlinger resulterer i elektriske signaler, som g0res synlige i en datamat, medens de ved hjælp af kniven opnàede mâleværdier mâ aflæses direkte af operat0ren og anvendes af denne. Ulempen ved den kendte frem-15 gangsmâde ligger sâledes i, at en subjektiv indfly-delse pâ mâleresultaterne ikke kan udelukkes, og at apparatet ikke selvstændigt og fuldautomatisk mulig-g0r en fastlæggelse af handelsklassen for parterede svinekroppe. Der bliver ved den kendte fremgangsmâde 20 benyttet to hândbetjente og pâ frit valgte steder pâ slagtekroppen anbringelige værkt0jer, sâ en kortere eller længere udtrækning af kablet muligg0r indfly-delse pâ mâleresultatet. Selv om man udelukker en be-vidst foretaget forfalskning af mâleresultaterne og 25 kun tager hensyn til mâlinger i overensstemmelse med en eller anden forskrift, kan der alligevel kun udf0-res ret vage og næppe sammenl igné lige mâlinger, ef-tersom mâlestederne, hvor kabelenderne skal lægges an, er afhængige af operat0rens subjektive bed0mmel-30 se.The method described above differs from the method prescribed in the Trade Class Regulation in that the mechanically provided length measurements result in electrical signals made visible in a computer, while the measured values obtained by the knife must be read directly by the operator and used by this. The disadvantage of the known method lies in the fact that a subjective influence on the measurement results cannot be ruled out and that the apparatus does not independently and fully enable a determination of the trading class for mated pig carcasses. In the known method 20, two hand operated and freely selected tools on the carcass are used, so that a shorter or longer extension of the cable allows influence on the measurement result. Even if a deliberate falsification of the measurement results is excluded and 25 only takes into account measurements in accordance with some regulation, only fairly vague and hardly comparable measurements can be taken, since the measuring points where the cable ends must be applied depend on the subjective judgment of the operator.
En yderligere forskel fremkommer derved, at den fremgangsmâde, der kan ud0ves med det kendte apparat, lægger andre kriterier til grund end dem, der forud- 5A further difference is found in that the method which can be practiced with the known apparatus assumes other criteria than those which precede it.

sættes ved bestemmelsen af handelsklasserne. Sâledes forekommer der for eksempel i forbindelse med den i det nævnte DE offentligg0relsesskrift nr. 2.512.374 beskrevne fremgangsmâde ingen konturmâling, hvilket 5 i0vrigt heller ikke ville være muligt med det viste apparat, eftersom man ikke med dette apparat kan an» give skinkens krumningsfor10b. Mâlingen foretages heller ikke pâ definerede og konstante steder, sâ mâlingen muligg0r subjektiv pâvirkning ved mâling pâ 10 forskellige k0dstykker. Endelig fremgâr det ikke af skriftet, at der skal fremskaffes et k0d/rygspækfor-hold og pâ hvilken màde, et sâdant forhold kan fremskaffes. Yderligere er det herfra kendte apparat ueg-net til fremskaffelse af k0d/rygspœkforholdet, da der 15 kun foretages en mekanisk længdemâling af spæktykkel-sen. Màleværkt0jets spids skal kun stikkes ind til bindevævet og mâ ikke trænge ind i k0det.is set by the determination of the trading classes. Thus, for example, there is no contour measurement in connection with the method described in the aforementioned DE Publication No. 2,512,374, which would otherwise also not be possible with the apparatus shown, since with this apparatus it is not possible to indicate the curvature of the ham. The measurement is also not done at defined and constant locations, so the measurement allows subjective influence when measuring 10 different pieces of meat. Finally, it does not appear from the document that a meat / backbone relationship must be obtained and in what way such a relationship can be obtained. Further, the apparatus known from here is unsuitable for providing the meat-to-skewer ratio, since only a mechanical length measurement of the specimen thickness is made. The tip of the measuring tool should only be inserted into the connective tissue and must not penetrate the meat.
En yderligere ulempe bestâr i, at den opnâede mâle-20 værdi ikke sammenlignes med en standardværdi i data-maten, men at den af datamaten oplyste mâleværdi mâ . bed0mmes af operat0ren under anvendelse af tabeller.A further disadvantage is that the measured value obtained is not compared with a standard value in the data feed, but that the measured value stated by the computer must. assessed by the operator using tables.
Heller ikke i dette tilfaelde kan en subjektiv ind-virkning pâ mâleresultatet udelukkes.Also, in this case, a subjective impact on the measurement result cannot be ruled out.

Fra tysk Offentligg0relsesskrift nr. 2.523.956 kendes et apparat, som tjener til mâling af spæktykkelse. I forbindelse med dette apparat anvendes en klinge, som st0des ind i et spæk/k0dlag indtil et anslag, sâledes 30 at et fotooptisk mâlemiddel kommer til at befindè sig i skillezonen mellem k0d- og spæklaget. Da k0det har andre reflektionsegenskaber end fedt, kan det sted, hvor bindevævet befinder sig, konstateres pâ grundlag af de optiske mâleresultater, hvorved man sâ vedFrom German Publication No. 2,523,956 an apparatus is known which serves to measure the thickness of the specter. In connection with this apparatus, a blade which is inserted into a blubber / meat layer is used up to a stop, such that a photooptic detergent will be in the separation zone between the meat and blubber layer. Since the meat has reflection properties other than fat, the place where the connective tissue is located can be determined on the basis of the optical measurement results, thus
DK 156526 BDK 156526 B
hjælp af dertil svarende beregninger kan finde af-standen mellem dette sted og anslaget. En angivelse af k0d/rygspækforholdet er imidlertid ikke mulig med dette apparat, eftersom det relativt lille mâleomrâde 5 stadig mâ være i umiddelbar nærhed af bindevævet, for at man kan konstatere lagtykkelsen. Yderligere har det i det her nævnte tyske offentligg0relsesskrïft beskrevne apparat den ulempe, at det igen drejer sig om et med hânden pâsat mâleinstrument, som derfor kan 10 pâsættes pâ et 0nsket sted pâ slagtekroppen, og det giver sâledes mulighed for subjektiv indflydelse. En yderligere fejlkilde er det, at anslaget kan trykkes mere eller mindre ind i det bl0de spæklag, sâledes at afstanden mellem bindevævet og spækoverfladen kan mâ-15 les forkert.using corresponding calculations can find the distance between this location and the estimate. However, an indication of the meat / backbone ratio is not possible with this apparatus, since the relatively small measuring area 5 must still be in the immediate vicinity of the connective tissue in order to ascertain the layer thickness. Furthermore, the apparatus described in the above-mentioned German publication has the disadvantage that it is again a hand-mounted measuring instrument, which can therefore be placed in a desired place on the carcass and thus allows for subjective influence. A further source of error is that the abutment can be pressed more or less into the soft blemish layer so that the distance between the connective tissue and the blubber surface can be measured incorrectly.
Den opgave ligger derfor til grund for opfindelsen at finde en fremgangsmâde og et apparat til bestemmelse af handelsklassen for k0d, hvilken fremgangsmâde og 20 apparat skal muligg0re en hurtig og objektiv bed0m-melse af de parterede kroppe fra forskellige krops-bygningstyper og en tilsvarende uforfalskelig indde-ling ien af handelsklasserne. I den forbindelse skal apparatet være lukket i sig selv og sikre en uafhæn-25 gig fuldautomatisk og uforanderlig arbejdsmâde, der ikke kan pâvirkes udefra, hvorhos betj eningen af apparatet ikke skal kræve uddannet personale.It is therefore an object of the invention to find a method and apparatus for determining the class of meat, which method and apparatus is to enable a quick and objective assessment of the partitioned bodies of different body types and a correspondingly unadulterated content. - one of the trading classes. In this connection, the appliance must be closed in its own right and ensure an independent, fully automatic and unchangeable working method which cannot be influenced from the outside, which operation of the appliance should not require trained personnel.
Dette formâl opnâs ved en fremgangsmâde af den oven-30 nævnte art, hvilken fremgangsmâde if01ge opfindelsen er særegen ved, at den parteredë slagtehalvkrop an-bringes og vejes pâ en vægt i et m0rkekammer og pâ de fastsatte mâlesteder belyses med en lyskilde med kon-stant dagslyslignende blandingslys, og at parametrene 7This object is achieved by a method of the aforementioned kind, which method according to the invention is peculiar in that the parterid slaughter half-body is placed and weighed on a weight in a darkroom and at the fixed measuring points is illuminated with a constant light source. daylight-like mixing light and that the parameters 7

5 Ved den opflndelsesmæsslge fremgangsmâde fremskaffes de n0dvendlge paramétré tll bestemmelse af handels-klassen, uden at slagtehalvkroppen bliver ber0rt me-kanisk og/eller ad elektrisk vej, og den efterf01gen-de vurdering af de fremskaffede paramétré udf0res e-10 lektronisk i et mikroprocessorsystem, sâ vurderingen bliver udf0rt efter objektive kriterier.5 In the inventive method, the necessary parameters for determining the class of trade are obtained without touching the carcass mechanically and / or electrically, and the subsequent assessment of the parameters obtained is carried out electronically in a microscope. so the assessment is carried out according to objective criteria.
Anbringelsen af farve-video-kameraet i et m0rkekam-mer, som har i det mindste én lyskilde til belysning 15 af de fastsatte mâlesteder pâ en i kammeret indf0rt slagtehalvkrop, giver mâlinger, som er uafhængige af ydre omgivelser.The placement of the color video camera in a dark chamber having at least one light source for illumination of the determined measuring points on a slaughter half-body introduced into the chamber provides measurements independent of external environment.
Til bestemmelse af handelsklassen fremskaffes mâle-20 teknisk en eller flere af f01gende paramétré: Skinke-konturen i det væsentlige i slagtehalvkroppens læng-deretning fra den bageste bagende over skinkesidefla-den til skillehvirvlen, den maksimale skinketykkelse i det væsentlige i en retning vinkelret pâ konturmâ-25 lingsretningen, spæktykkelsen, forholdet mellem ryg-spæk og rygk0d samt vægten af slagtehalvkroppen.To determine the trade class, measurement or measurement is technically provided by one or more of the following parameters: the ham contour substantially in the longitudinal direction of the carcass half from the posterior rear over the ham side surface to the vertebra, the maximum ham thickness substantially perpendicular to the contour. -25 the direction of lactation, the thickness of the bacon, the relationship between the spinal cord and the spinal cord, as well as the weight of the carcass.
Farve-video-kameraet optegner fortrinsvis sorte (Kam-mervæggen), hvide (Fedt) og r0de (K0d) kontrastkontu-30 rer og omsætter disse i elektriske impulser, som kan vurderes i det tilsluttede mikroprocessorsystem.The color video camera preferably records black (Kam marrow), white (Grease) and red (K0d) contrast contours and converts these into electrical pulses which can be evaluated in the connected microprocessor system.
Til forbedring af vurderingen kan man fordelagtigt forstærke kontrasterne pâ halvkroppen ved kontrast- 8To improve the assessment, the contrasts on the half-body can be advantageously enhanced by contrast 8
DK 156526 BDK 156526 B
midler og/eller lade disse forstærke i kamera-mikro-processorsystemet. Hertil kan i og for sig kendte forstærker- eller filterkredsl0b anvendes. Ved rene snitflader er kontrastkonturerne adskilt relativt 5 skarpt fra hverandre, fordi der i overgangen mellem et fedtlag og et k0dlag befinder sig et lag af binde-væv, som tydeligt adskiller disse to lag, hvorfor der ved fejlbehæftede mâlinger ikke kan optegnes nogen konturlinie. Fejlmâlinger, som kan opstâ gennem et 10 dârligt snit eller ved tilsmudsning eller lignende forurening, kan derfor straks detekteres og afmærkes af vurderingssystemet.means and / or allow these to amplify in the camera micro-processor system. For this purpose amplifier or filter circuits known per se can be used. For clean cut surfaces, the contrast contours are separated relatively sharply from each other because in the transition between a fat layer and a meat layer there is a layer of connective tissue that clearly separates these two layers and therefore no contour line can be drawn in case of faulty measurements. Therefore, error measurements which may occur through a poor cut or by soiling or similar contamination can be immediately detected and marked by the assessment system.
Et yderligere fordelagtigt træk ved den opfindelses-15 mæssige fremgangsmâde beror pâ, at anbringelsen af klassificeringskendetegnet pâ slagtehalvkroppen efter vurderingen af denne anbringes ber0ringsfrit, for-trinsvist ved hjælp af en laser.A further advantageous feature of the inventive method is that, after assessing it, the affixing of the classification characteristic to the carcass half is preferably applied by a laser.
20 Fordelen herved er, at man udover den ber0ringsfrie anbringelse af klassificeringskendetegnet ogsâ opnâr en forfalskningssikker anbringelse af tegnet og yder-ligere undgâr, at dele af slagtehalvkroppen bliver forsynet med uæstetisk virkende stempelfarver.20 The advantage of this is that, in addition to the contactless application of the classification characteristic, a falsely safe application of the sign is also obtained, and furthermore that parts of the carcass half-body are provided with unaesthetically acting stamp colors.
25 Mâleindretningen, styre- og oplagringsapparatet, skriveapparatet og indretningen til ber0ringsfri anbringelse af klassificeringskendetegnet er fordelag-tigt forbundet i række.The measuring device, the control and storage apparatus, the typewriter and the device for contactless application of the classification characteristic are advantageously connected in series.
