Opfindelsen angår et apparat til midtdeling af hovedet på flækkede, i bagbenene ophængte grisekroppe, der fremføres i hovedsagen ensartet orienteret.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to an apparatus for centering the head of spotted pig carcasses suspended in the hind legs which are conveyed substantially uniformly.

Den spaltning af grisekroppe i to halvdele, som finder sted i slagte-5 rier, foretages i reglen ved savning. Der er ingen vanskeligheder ved at save en grisekrop igennem fra halen til kraniet, men når saven går ned i kraniet, er den tilbøjelig til at hugge og er vanskelig at styre. Desuden frembringes der ved gennemsavning af kraniet temmelig meget smuld, som forurener varerne.The split of pig carcasses into two halves that takes place in slaughterhouses is usually done by sawing. There is no difficulty in cutting a pig's body from the tail to the skull, but when the saw goes down the skull, it tends to chop and is difficult to control. In addition, through the skull penetration, quite a lot of dirt is produced which contaminates the goods.

10 Det er også kendt at flække grisehovedet med en flækkeøkse, men ved denne proces frembringes der let splinter, som kan være skarpe og spidse og derfor farlige, hvis de trænger ind i slagteriprodukter.10 It is also known to split the pig's head with a split ax, but in this process, splinters are easily produced which can be sharp and pointed and therefore dangerous if they penetrate slaughterhouse products.

I moderne svineslagterier befordres svinekroppene ophængt i en transportør fra det ene behandlingssted til det andet. Før denne såkaldte linie-15 slagtning blev indført, blev svinekroppene parteret og de enkelte dele fordelt mellem forskellige behandlingssteder. Til kløvning af grisehoveder kendtes forskellige apparater med et fast bord, på hvilket hovedet kunne anbringes i en mere eller mindre veldefineret stilling under et kraftdrevet kløveorgan. I et af disse kendte apparater var kløveor-20 ganet anbragt på den ene ende af en arm, som ved den anden ende var hængslet til bordet, og som gennem en plejlstang var forbundet med en motordreven krumtap. Sådanne apparater med faste borde ville være uanvendelige eller i hvert fald meget besværlige at anvende i et moderne linieslagteanlæg på grund af vanskelighederne ved at placere det på 25 grisekroppen fastsiddende hoved i en bestemt stilling under kløveorganet på et fast bord, og de ville slet ikke være i stand til at arbejde med den hastighed, en sådan anvendelse ville kræve.In modern pig slaughterhouses, the pig carcasses are transported in a conveyor from one treatment site to another. Before this so-called line-15 slaughter was introduced, the pig carcasses were partitioned and the individual parts distributed among different treatment sites. For splitting pig heads, various apparatus with a fixed table were known on which the head could be placed in a more or less well-defined position under a power-driven splitting device. In one of these known devices, the splitting device was arranged on one end of an arm which was hinged to the table at the other end and which was connected to a motor driven crank through a connecting rod. Such fixed-table appliances would be useless or at least very cumbersome to use in a modern line slaughter plant because of the difficulty of placing the head of the pig body in a particular position under the splitting means on a fixed table, and they would not be at all capable of working at the speed such an application would require.

Opfindelsen har til formål at angive et apparat af den omhandlede art, som er i stand til at flække et grisehoved i to symmetriske halvdele 30 uden at frembringe hverken smuld eller splinter, og som egner sig til anvendelse i et moderne slagteri med linieslagtning.The invention has for its object to provide an apparatus of the kind which is capable of tearing a pig's head into two symmetrical halves 30 without producing neither crumbs nor splinters and which is suitable for use in a modern slaughterhouse with line slaughter.

-2- 146991-2- 146991

Dette formål opnås ved, at apparatet er udformet som angivet i krav 1's kendetegnende del. Apparatet kan ophængt, fx i en elastisk ophængt wire eller i et stangsystem, let manøvreres i korrekt arbejdsstilling i forhold til hovedet på en gris, der hænger ved bagbenene i en transportør, 5 og det kileformede flækkeorgan er i stand til at flække grisehovedet rent langs kraniets sutura parietalis, frontalis og nasalis, som er den langs kraniets midte forløbende naturlige sammenvoksningslinie, langs hvilken flækning foregår lettere end gennem massivt knoglevæv, idet saven har savet en rille i kraniets bageste del langs dets sammenvoks-10 ningsmidtlinie. Under denne proces fikseres grisehovedet ved hjælp af holderen, og den pneumatiske eller hydrauliske cylinder kan frembringe en passende hurtig og jævn bevægelse af flækkeorganet i forhold til holderen.This object is achieved by the apparatus being designed as defined in the characterizing part of claim 1. The apparatus can be suspended, for example in an elastic suspended wire or in a bar system, easily maneuvered in the correct working position relative to the head of a pig hanging by the hind legs of a conveyor, and the wedge-shaped splitting means is able to tear the pig head cleanly along the skull's sutura parietalis, frontalis and nasalis, which is the natural coagulation line extending along the center of the skull, along which splicing is easier than through solid bone tissue, the saw having a groove in the posterior part of the skull along its midline of the skull. During this process, the pig head is fixed by means of the holder, and the pneumatic or hydraulic cylinder can produce a suitably rapid and smooth movement of the splitting member relative to the holder.

Ved den i krav 2 angivne udformning af holderen opnås dels, at apparatet 15 kan bringes på plads i forhold til grisehovedet ved en ren sideværts bevægelse, når klappen er svinget ned, dels at hovedets forparti fikseres effektivt i holderen, når klappen er svinget op.The configuration of the holder as claimed in claim 2 is achieved partly that the apparatus 15 can be brought into position relative to the pig head by a clean lateral movement when the flap is swung down and partly that the front part of the head is fixed effectively in the holder when the flap is swung up.

Kontrolhensyn kræver, at de to halvparter, hvori en gris deles, forbliver sammenhængende ved trynebrusken, og dette opnås ved, at holderen er 20 udformet som angivet i krav 3, idet flækkeorganet ved denne konstruktion ikke vil trænge helt igennem den i fordybningen hvilende tryne.Control considerations require that the two halves into which a pig is split remain coherent at the cartilage, and this is achieved by holding the holder 20 as defined in claim 3, as the splice means of this construction will not fully penetrate the groove resting in the recess.

En særlig enkel udformning af apparatet er angivet i krav 4.A particularly simple design of the apparatus is given in claim 4.

Ved den i krav 5 angivne udformning opnås på enkel måde automatisk aktivering af holderens klap på det rette tidspunkt i forhold til aktive-25 ringen af flækkeorganet.In the embodiment set out in claim 5, simple activation of the flap of the holder at the correct time relative to the activation of the splitting means is achieved in a simple manner.

Opfindelsen skal forklares nærmere i det følgende under henvisning til tegningen, hvor 146991 -3- fig. 1 skematisk viser en udførelsesform for apparatet ifølge opfindelsen, set fra siden, fig. 2 et længdesnit gennem holderen med flækkekniven i anlæg mod holderbunden, og 5 fig. 3 et snit efter linie III—III i fig. 1.BRIEF DESCRIPTION OF THE DRAWINGS The invention will be explained in more detail below with reference to the drawing, in which FIG. 1 is a schematic side view of an embodiment of the apparatus according to the invention; FIG. 2 is a longitudinal section through the holder with the splitting knife in contact with the holder base; and FIG. 3 is a sectional view taken along line III-III of FIG. First

I fig. 1 er 1 og 2 arme, der ved den ene ende er drejeligt forbundet med hinanden ved et hængsel 3. På den anden ende af den nedre arm 1 er der anbragt en i hovedsagen tragtformet holder 4 til optagelse af forpartiet af hovedet af en gris 5, der tilføres apparatet på sædvan-10 lig måde hængende i bagbenene i en transportør. Når grisen ankommer til apparatet, er den gennemsavet fra halen til kraniet, og saven har yderligere savet en rille i kraniets bageste del langs dets sammen-voksningsmidtlinie. På den ydre ende af den øverste arm 2 er der fastgjort en flækkekniv 6 med en nedadvendende, krum, konkav æg. Som det 15 fremgår af fig. 3, har flækkekniven kileformet tværsnit og en ret stump, afrundet æg.In FIG. 1, 1 and 2 are arms that are pivotally connected at one end by a hinge 3. At the other end of the lower arm 1 is provided a generally funnel-shaped holder 4 for receiving the front portion of the head of a pig 5 which is applied to the apparatus in the usual manner hanging in the hind legs of a conveyor. When the pig arrives at the appliance, it is cut from the tail to the skull, and the saw has further cut a groove in the rear of the skull along its coaxial midline. On the outer end of the upper arm 2 is attached a splitting knife 6 with a downwardly curving, concave egg. As shown in FIG. 3, the split knife has wedge-shaped cross section and a rather blunt, rounded egg.

Bag kniven 6 danner armen 2 en kasseformet ramme 7, hvori en pneumatisk cylinder 8 er drejeligt fastgjort ved hjælp af omdrejningstappe 9. Cylinderens stempelstang 10 er ved 11 drejeligt forbundet med den nedre 20 arm 1.Behind the knife 6, the arm 2 forms a box-shaped frame 7, in which a pneumatic cylinder 8 is pivotally secured by pivot pin 9. The piston rod 10 of the cylinder is pivotally connected to the lower 20 arm 1 at 11.

Holderen 4's forvæg udgøres af en klap 12, der er svingbar om et ved holderens bund 14 beliggende hængsel 13 mellem den med fuldt optrukne linier viste åbne stilling og den med punkterede linier viste lukkede stilling. En på klappen 12 anbragt arm 15 er ved 16 drejeligt forbun-25 det med stempelstangen 17 i en pneumatisk cylinder 18, der ved 19 er drejeligt fastgjort til holderarmen 1.The front wall of the holder 4 is constituted by a flap 12 which is pivotable about a hinge 13 located at the base 14 of the holder 14 between the open position shown with fully drawn lines and the closed position shown by dashed lines. An arm 15 located on the flap 12 is pivotally connected at 16 to the piston rod 17 in a pneumatic cylinder 18 which at 19 is pivotally attached to the holder arm 1.

146991 -4- På knivarmen 2 er anbragt to håndtag 20 og 21, og på eller i umiddelbar nærhed af hvert håndtag sidder en ikke vist betjeningsknap. Når og kun når begge disse knapper aktiveres samtidigt, føres der trykluft til de to pneumatiske cylindre 8 og 18, hvorved klappen 12 lukkes, og flække-5 kniven trykkes ned mod holderen, indtil dens æg støder imod holderbun-den 14, som vist i fig. 2, idet den går ned i ikke viste slidser i klappen 12 og i holderens bagvæg. Under denne bevægelse går knivæggen først ned i den af saven frembragte rille i kraniets bageste del og flækker derefter grisehovedet langs kraniets langsgående sammenvoksningslinie.Two knobs 20 and 21 are arranged on the knife arm 2 and on or in the immediate vicinity of each handle is a control knob not shown. When and only when both of these buttons are actuated simultaneously, compressed air is supplied to the two pneumatic cylinders 8 and 18, thereby closing the flap 12 and pressing the splitting knife 5 against the holder until its eggs abut the holder base 14, as shown in FIG. FIG. 2, as it goes down into slots not shown in the flap 12 and in the back wall of the holder. During this movement, the knife wall first descends into the groove produced by the saw in the rear of the skull and then splits the pig head along the longitudinal line of the skull.

10 Når knapperne slippes, vender cylindrene og de deraf bevægede dele tilbage til deres begyndelsesstillinger.10 When the buttons are released, the cylinders and their moving parts return to their initial positions.

Som vist i fig. 2 er der i den bageste del af holderbunden 14 udformet en fordybning 22, som grisens tryne går ned i. Da flækkekniven 6 standser sin bevægelse, når dens æg støder imod den forreste del af holder-15 bunden 14 efter at have gennemskåret grisens underkæbe, vil trynen ikke blive skåret helt igennem, og de to halvparter, hvori grisen er blevet delt, vil således hænge sammen ved trynebrusken.As shown in FIG. 2, a recess 22 is formed in the rear portion of the holder base 14 into which the pig's thrusts go down. As the splitting knife 6 stops its movement when its eggs abut the front part of the holder base 14 after cutting the pig's lower jaw, the trine will not be cut through completely and the two halves into which the pig has been divided will thus be connected to the trine cartilage.

Apparatet kan hensigtsmæssigt være ophængt i en wire 23 fra et ikke vist fjederophæng, der selv kan være ophængt i en løbekat, som løber 20 på en om en lodret akse svingbar bom.The apparatus may conveniently be suspended in a wire 23 from a spring suspension not shown, which itself may be suspended in a running cat running 20 on a boom swingable about a vertical axis.

Flækkekniven vil kunne være således anbragt, at den foretager en trans-latorisk bevægelse i stedet for en svingningsbevægelse i forhold til holderen. Denne bevægelse kunne også være intermitterende i stedet for kontinuerlig og kunne fx frembringes ved hjælp af en slagmekanisme.The splicing knife may be arranged so that it performs a translational movement instead of a pivoting movement relative to the holder. This movement could also be intermittent instead of continuous and could be produced, for example, by means of a stroke mechanism.

25 Det er også muligt at frembringe en kontinuerlig bevægelse af flækkekniven på andre måder end ved hjælp af en pneumatisk eller hydraulisk cylinder, fx ved hjælp af en kam- eller krumtapmekanisme.It is also possible to produce a continuous movement of the splitting knife by other means than by means of a pneumatic or hydraulic cylinder, for example by means of a cam or crank mechanism.
