Den foreliggende opfindelse angår en fremgangsmåde og et apparat til ophængning af et på en transportør fremført kødstykke på et spidst opadragende element af et transportorgan. I det følgende vil dette element for 5 nemheds skyld blive kaldt en krog.The present invention relates to a method and apparatus for hanging a piece of meat conveyed on a conveyor onto a pointed upwardly extending member of a conveyor. In the following, for 5 convenience this element will be called a hook.

På slagterier, navnlig svineslagterier, bruges det til intern eller ekstern transport at ophænge kødstykker på et transportorgan, der normalt betegnes et juletræ. Kødstykkerne kan være eksempelvis forender, 10 midterstykker eller skinker. Et juletræ af den her nævnte art er en lodret metalstang, som ved sin ene ende har en ombøjning for ophængning i en giidestang, og som i ækvidistante niveauer har fire kroge, som rager ud til hver sin side. Der er sædvanligvis fire 15 eller fem niveauer af kroge.In slaughterhouses, in particular pig slaughterhouses, it is used for internal or external transport to hang pieces of meat on a transport organ, usually called a Christmas tree. The pieces of meat can be, for example, ends, 10 center pieces or hams. A Christmas tree of the kind mentioned here is a vertical metal bar, which at one end has a bend for hanging in a guide rod, and which at equidistant levels has four hooks which protrude to each side. There are usually four 15 or five levels of hooks.

Ophængning af kødstykkerne på juletræerne sker i dag sædvanligvis manuelt, hvilket er et tungt arbejde, da de enkelte kødstykker ofte vejer ca. 10 kg. Dertil kommer, at kødstykkerne for at få sværen gennembrudt, 20 hvis de ophænges med juletræets krog i sværsiden, må slås mod krogen.Today, hanging the pieces of meat on the Christmas trees is usually done manually, which is a heavy task, as the individual pieces of meat often weigh approx. 10 kg. In addition, the pieces of meat in order to have the sore pierced, 20 if they are hung with the hook of the Christmas tree in the sear, must be struck against the hook.

Det kendes fra DK patent nr. 153 079 at anvende en robot til ophængningen, hvor robotten i det væsentlige eftergør det manuelle arbejde, dvs. tager kødstykkerne 25 et for et, efterhånden som de ankommer på et transportbånd, og hænger dem op på juletræet.It is known from DK patent no. 153 079 to use a robot for the suspension, in which the robot essentially mimics the manual work, ie. take the pieces of meat 25 one by one as they arrive on a conveyor belt and hang them on the Christmas tree.

Formålet med den foreliggende opfindelse er at tilvejebringe en ny fremgangsmåde og et apparat af den indledningsvis anførte art, hvorved ophængningen kan 30 automatiseres helt eller delvis, således at slagteriarbejderen fritages for det tunge ophængningsarbejde.The object of the present invention is to provide a new method and apparatus of the kind mentioned in the preamble, whereby the suspension can be fully or partially automated, so that the butchery worker is exempted from the heavy suspension work.

Dette opnås ved hjælp af en fremgangsmåde, der er særegen ved, at transportorganet holdes ved nedstrøm-senden af transportøren, så nedstrømsenden har en 35 position over krogens niveau, at kødstykket ledes til 2 DK 173832 B1 en position over krogen, og at kødstykket slås eller presses ned på krogen. Derved opnås, at det ikke er nødvendigt at løfte kødstykket.This is achieved by a method which is peculiar in that the conveyor is held at the downstream transmitter by the conveyor so that the downstream end has a position above the level of the hook, that the meat piece is led to a position above the hook and that the meat piece is struck. or pressed down on the hook. In this way, it is not necessary to lift the piece of meat.

Transportøren og krogen bevæges fortrinsvis lodret 5 i forhold til hinanden efter at kødstykket er ledt til en position over krogen, således at transportørens nedstrøms ende sænkes i forhold til krogen, inden det bliver slået eller presset, og således, at det med sikkerhed vil blive slået eller presset ned på krogen, 10 således at forstå, at krogen gennembryder kødets overflade, det vil ofte sige sværen.The conveyor and hook are preferably moved vertically relative to one another after the piece of meat is guided to a position above the hook so that the downstream end of the conveyor is lowered relative to the hook before being struck or pressed, and so that it will be struck safely. or pressed down on the hook, 10 so as to understand that the hook pierces the surface of the meat, that is to say, often the hard.

En udførelsesform af fremgangsmåden ifølge opfindelsen er særegen ved, at kødstykket fastholdes i et fikstur på transportøren, idet kødstykket fastholdt i 15 fiksturet ledes til positionen over krogen. Herved bliver kødstykket effektivt fikseret i forhold til krogen, medens denne trykkes ind i kødstykket, hvilket især har betydning, når kødstykkets overflade er sej, som tilfældet fx er ved svær på svinekød. Det kan 20 herunder være fordelagtigt, at kødstykkets overflade gennembrydes, medens det befinder sig i fiksturet, inden det ledes til positionen over krogen.An embodiment of the method according to the invention is peculiar in that the meat piece is held in a fixture on the conveyor, the meat piece held in the fixture being guided to the position above the hook. Hereby the piece of meat is effectively fixed with respect to the hook while it is pressed into the piece of meat, which is especially important when the surface of the piece of meat is tough, as is the case, for example, in severe pork. Among other things, it may be advantageous for the surface of the meat piece to be pierced while in the fixture before being guided to the position above the hook.

Formålet opfyldes endvidere ved hjælp af et apparat af den indledningsvis anførte art, som er 25 særegent ved, at apparatet omfatter midler indrettet til at holde transportorganet ved nedstrømsenden af transportøren, så nedstrømsenden har en position over krogens niveau, og at der er midler indrettet til direkte eller indirekte at presse eller slå kødstykket 30 mod krogen, efter at det på transportøren anbragte kødstykke er ledt til en position over krogen. Midlerne til at presse eller slå kødstykket mod krogen kan med fordel være et presseelement i form af en pneumatisk hammer, dvs. en pneumatisk cylinder, hvis stempelstang 35 bærer en klods eller en plade for enden.The object is further accomplished by means of an apparatus of the kind set out in the preamble, which is peculiar in that the apparatus comprises means arranged to hold the conveying means at the downstream end of the conveyor, so that the downstream end has a position above the level of the hook and means are provided for directly or indirectly pressing or striking the piece of meat 30 against the hook after the piece of meat placed on the conveyor is led to a position above the hook. The means for pressing or striking the piece of meat against the hook may advantageously be a pressing element in the form of a pneumatic hammer, ie. a pneumatic cylinder whose piston rod 35 carries a block or plate at the end.

Apparatet omfatter fortrinsvis midler indrettet til at bevæge transportøren og krogen lodret i forhold til hinanden, således at transportørens nævnte ende sænkes i forhold til krogen. Disse midler kan, dersom 5 der ikke anvendes en pneumatisk hammer til at slå eller presse kødstykket mod krogen tillige tjene til at føre kødstykket mod krogen med så stor kraft, at krogen trænger ind i kødstykket i tilstrækkelig dybde til, at det hænger sikkert på krogen, og eventuelt ved, at der 10 på transportøren findes organer, der under presningen holder kødstykket fast i forhold til transportøren.Preferably, the apparatus comprises means arranged to move the conveyor and the hook vertically relative to each other so that the said end of the conveyor is lowered relative to the hook. These means, if a pneumatic hammer is not used to strike or press the piece of meat against the hook, can also serve to guide the piece of meat against the hook with such force that the hook penetrates the piece of meat to a sufficient depth to hang it securely on the hook. and, optionally, knowing that there are 10 on the conveyor means which during pressing comprise the piece of meat relative to the conveyor.

Yderligere kan transportøren i en anden udførelsesform omfatte et eller flere fiksturer for kødstykker, der skal ophænges, samt en indretning til at åbne 15 fiksturet, efter at kødstykket er slået eller presset ned på krogen. Fiksturet sikrer, at kødstykkerne placeres således, at krogen rammer kødstykket på det tilsigtede sted, så det ophænges korrekt. Eventuelt kan der være organer til gennembrydning af kødstykkets 2 0 overflade, inden det føres frem til positionen over krogen. Fiksturet sikrer da, at krogen rammer kødstykket ud for det område, der forinden er blevet gennembrudt .In addition, in another embodiment, the conveyor may comprise one or more fixtures for pieces of meat to be hung, as well as a device for opening the fixtures after the meat piece has been knocked or pressed down on the hook. The fixture ensures that the pieces of meat are positioned so that the hook hits the meat piece in the intended place so that it is hung correctly. Optionally, there may be means for piercing the surface of the piece of meat before advancing to the position above the hook. The fixture then ensures that the hook strikes the piece of meat off the area previously pierced.

I en udførelsesform, hvor krogen sidder på en 25 lodret stang, der er ophængt i sin ene ende, dvs. på et juletræ, omfatter apparatet fortrinsvis organer indrettet til i det væsentlige i niveau med krogen at støtte og positionere stangen i vandret plan i det mindste i retning mod/fra transportøren.In one embodiment, the hook sits on a vertical bar suspended at one end, i. on a Christmas tree, the apparatus preferably comprises means adapted to substantially support and position the bar in a horizontal plane at least in the direction towards / from the conveyor.

30 Derved sikres det, at krog og stang ikke viger bort fra transportørens ende og kødstykket, når kødstykket presses eller slås ned over krogen.In this way, it is ensured that the hook and bar do not deviate from the end of the conveyor and the piece of meat when the piece of meat is pressed or knocked over the hook.

Endvidere omfatter apparatet fortrinsvis organer indrettet til at centrere krogen i forhold til trans-35 portørens nedstrøms ende. Sådanne organer er med til at 4 DK 173832 B1 sikre, at krog og kødstykke rammer hinanden korrekt. Endvidere findes der fortrinsvis styr indrettet til at centrere kødstykket på transportøren, hvilket yderligere er med til at sikre, at krog og kødstykke rammer 5 hinanden korrekt.Further, the apparatus preferably comprises means adapted to center the hook relative to the downstream end of the conveyor. Such organs help ensure that the hook and piece of meat hit each other correctly. Furthermore, guides are preferably provided for centering the piece of meat on the conveyor, which further helps ensure that the hook and piece of meat strike each other correctly.

I en foretrukket udførelsesform, hvor transportøren kun har mindre bevægelighed i forhold til juletræet, kan apparatet med fordel omfatte et skubbeorgan indrettet til at skubbe kødstykket sideværts af 10 transportøren. Derved opnås, at kødstykket vil trække juletræet med sig, dvs. dreje det om stangens længderetning, hvorved en ny krog vil blive drejet i position til at modtage det næste kødstykke.In a preferred embodiment, in which the conveyor has only less movement relative to the Christmas tree, the apparatus may advantageously comprise a pushing means adapted to push the meat piece laterally of the conveyor. This results in the fact that the piece of meat will pull the Christmas tree with it, ie. rotate it about the longitudinal direction of the rod, whereby a new hook will be rotated into position to receive the next piece of meat.

Endelig strækker transportøren sig i retning mod 15 krogen fortrinsvis skråt opad. Derved opnås, at krogen, hvis ende typisk strækker under en vinkel på ca. 45° i forhold til lodret, får en mindre indfaldsvinkel til kødstykket end tilfældet ville være, hvis transportøren strakte sig vandret.Finally, the conveyor extends towards the hook preferably inclined upward. This results in the fact that the hook, whose end typically extends at an angle of approx. 45 ° relative to the vertical, a smaller angle of incidence to the piece of meat is obtained than would be the case if the conveyor stretched horizontally.

20 Opfindelsen skal i det følgende beskrives nærmere under henvisning til tegningen, der viser udførelseseksempler på opfindelsen. På tegningen viser:BRIEF DESCRIPTION OF THE DRAWINGS The invention will now be described in more detail with reference to the accompanying drawings which illustrate exemplary embodiments of the invention. In the drawing:

Fig. 1 et udførelseseksempel på et apparat vist i et trin af fremgangsmåden ifølge opfindelsen, hvor et 25 kødstykke befinder sig på transportbåndet umiddelbart før nedpresning på en krog i en halvautomatisk proces, fig. 2 et andet apparat ifølge opfindelsen og med et teleskoptransportbånd i et tilsvarende trin af fremgangsmåden, og 30 fig- 3 en tredje udførelsesform med et transport bånd med en tragt, der styrer kødstykket ved fremføringen mod krogen.FIG. 1 shows an embodiment of an apparatus shown in a step of the method according to the invention, where a piece of meat is on the conveyor belt immediately before pressing on a hook in a semi-automatic process; 2 shows a second apparatus according to the invention and with a telescopic conveyor belt in a corresponding step of the method, and FIG. 3 shows a third embodiment with a conveyor belt having a hopper guiding the piece of meat in the feed towards the hook.

Et juletræ 1 hænger på en gi idestang 2, der kan hæves og sænkes efter et bestemt program, der taktes 35 frem af en operatør. Juletræet 1 støttes af en dobbelt 5 DK 173832 B1 rulle 4, der er udformet således, at en krog kan hæves mellem dobbeltrullens to dele. En krog 8, hvorpå et kødstykke 16 skal ophænges, bringes i nøjagtig position ved hjælp af en styrestang 3, der griber om krogen 8 5 tæt ved ophængningsstedet. Kødstykket 16 føres ved hjælp af et transportbånd 5 hen over krogen 8, medens denne sammen med resten af juletræet 1 er sænket eksempelvis tre centimeter i forhold til det på tegningen viste for at sikre kødstykket 16 fri passage 10 frem til den på tegningen viste placering.A Christmas tree 1 hangs on a giant idler 2 that can be raised and lowered after a particular program that is clocked 35 by an operator. The Christmas tree 1 is supported by a double roll 4, which is designed so that a hook can be raised between the two parts of the double roll. A hook 8 on which a piece of meat 16 is to be hung is brought into exact position by means of a guide rod 3 which grips the hook 8 5 close to the hanging place. The piece of meat 16 is conveyed by means of a conveyor belt 5 over the hook 8, while it, together with the rest of the Christmas tree 1, is lowered, for example, three centimeters from that shown in the drawing to ensure free passage 10 of the meat piece 16 to the position shown in the drawing.

På tegningen er juletræet 1 vist delvis fyldt, idet allerede på juletræet 1 hængende stykker 10-15 er ophængt i nummerorden.In the drawing, the Christmas tree 1 is shown partially filled, since already on the Christmas tree 1 hanging pieces 10-15 are suspended in number order.

Ophængningen af kødstykket 16 foregår som følger: 15 Juletræet 1 er af operatøren eller et mekanisk drejear-rangement drejet efter ophængningen af delstykket 15. Juletræet sænkes eksempelvis tre centimeter og styrestangen 3 går i indgreb med krogen 8 og med hjælp fra modholdet fra dobbeltrullen 4 og ophængningen i gli-20 destangen 2 holdes juletræet i korrekt position.The hanging of the meat piece 16 is carried out as follows: The Christmas tree 1 is rotated by the operator or a mechanical pivot arrangement after the hanging of the part 15. The Christmas tree is lowered, for example, three centimeters and the guide rod 3 engages the hook 8 and with the help of the restraint from the double roll 4 and the hanging in the slide rod 2 holds the Christmas tree in the correct position.

Kødstykket 16 føres frem af transportbåndet 5 til det er i den på tegningen viste position over krogen 8, hvorefter operatøren aktiverer en kontakt.The meat piece 16 is advanced by the conveyor belt 5 until it is in the position shown in the drawing above the hook 8, after which the operator activates a contact.

Herefter hæves giidestangen 2 ca. tre centimeter 25 svarende til den førnævnte sænkning, således at kødstykket 16 hviler på krogen 8 som vist på tegningen. Et presse- eller slagværktøj 6 støder med et kort stød plade 7 over mod kødstykket 16 over krogen 8, som derved gennembryder kødstykkets 16 svær og trænger 30 lidt ind i det underliggende kød.Then the guide rod 2 is raised approx. three centimeters 25 corresponding to the aforementioned lowering so that the piece of meat 16 rests on the hook 8 as shown in the drawing. A pressing or impacting tool 6 abuts with a short impact plate 7 against the piece of meat 16 over the hook 8, which thereby breaks the severity of the meat piece 16 and penetrates 30 slightly into the underlying meat.

Styrestangen 3 trækkes derefter fri af juletræets krog 8 og operatøren skubber kødstykket 16 sidelæns, således at juletræet med kødstykket 16 drejes med uret og kødstykket 16 falder ned af transportbåndet 5, så 3 5 det hænger ned langs juletræet og hviler mod det 6 DK 173832 B1 underliggende kødstykke 12.The guide rod 3 is then pulled free from the hook 8 of the Christmas tree and the operator pushes the piece of meat 16 sideways so that the Christmas tree with the piece of meat 16 is rotated clockwise and the piece of meat 16 falls down from the conveyor belt 5, so that it hangs down along the Christmas tree and rests against it 6 DK 173832 B1 underlying piece of meat 12.

Processen gentages til der hænger fire kødstykker i samme niveau, hvorefter juletræet 1 sænkes, til næste overliggende sæt kroge passer ud for transportbåndet 5.The process is repeated until four pieces of meat are hung in the same level, after which the Christmas tree 1 is lowered until the next overlying set of hooks fits next to the conveyor belt 5.

5 Efter at de øverste kroge er fyldt, føres juletræet 1 væk ad giidestangen 2 og et tomt juletræ føres frem og hæves, så krogene i nederste niveau er ud for transportbåndet 5.5 After the top hooks are filled, the Christmas tree 1 is led away by the guide rod 2 and an empty Christmas tree is advanced and raised so that the lower level hooks are next to the conveyor belt 5.

I stedet for en sænkning og hævning af glidestan-10 gen kan det alternativt være hensigtsmæssigt, at transportbåndet 5 kan udføre en vippebevægelse, således at den nedstrøms ende kan bevæges ca. 3 cm i forhold til spidsen af krogen 8 på juletræet 1.Alternatively, instead of lowering and raising the sliding rod 10, it may be desirable for the conveyor belt 5 to perform a tilting movement so that the downstream end can be moved about 10 times. 3 cm from the tip of the hook 8 on the Christmas tree 1.

Processen kan automatiseres, hvis der foretages en 15 automatisk orientering af kødstykket, inden det tilføres transportbåndet 5. På transportbåndet 5 skal der opsættes en detektor, soro stopper båndet, når et kødstykke er over krogen 8, og aktiverer slagværktøjet.The process can be automated if an automatic orientation of the piece of meat is made before it is fed to the conveyor belt 5. On the conveyor belt 5, a detector must be installed, the soro stops the belt when a piece of meat is over the hook 8 and activates the impact tool.

Ved transportbåndet skal desuden monteres styrestænger, 20 der fastholder kødstykket sideværts under sværgennem-brydningen og derefter skubber kødstykket sidelæns, således at juletræ og kødstykke drejes med uret.In addition, at the conveyor belt control rods must be mounted, 20 which hold the piece of meat laterally during the break-through and then push the piece of meat sideways, so that the Christmas tree and the piece of meat are rotated clockwise.

Det er normalt ikke hensigtsmæssigt at skulle foretage andre bevægelser af juletræet 1 end dem, som 25 er nødvendige for at bringe en ny krog på plads foran den nedstrøms ende af transportbåndet. Det kan ligeledes være uhensigtsmæssigt, at kødstykkerne, efter at de er presset fast på krogen, skal falde på plads efter at være blevet skubbet i sideretningen i forhold 30 til krogen. Fig. 2 viser en anden udførelsesform, hvor der er taget hensyn til disse forhold. Transportbåndet 5 er udformet som et såkaldt teleskopbånd med en bevægelig front 21, som, når slæden 22 med frontrullen 23 og en ekstra rulle skydes mod venstre på figuren, så 35 at sige fjerner transportbåndet 5 under kødstykket 16.It is usually not appropriate to have to make other movements of the Christmas tree 1 other than those necessary to bring a new hook in place in front of the downstream end of the conveyor belt. It may also be inconvenient for the pieces of meat, after being pressed onto the hook, to fall into place after being pushed sideways relative to the hook. FIG. 2 shows another embodiment in which these conditions are taken into account. The conveyor belt 5 is designed as a so-called telescopic belt with a movable front 21 which, when the carriage 22 with the front roller 23 and an additional roller is pushed to the left of the figure, 35 so as to remove the conveyor belt 5 under the meat piece 16.

7 DK 173832 B1 På lignende måde som vist på fig. 1 skal der findes presseorganer, som slår eller presser en frit ud fra den nedstrøms ende af transportbåndet udragende del af kødstykket 16 ned mod krogen. Samtidig eller umiddel-5 bart herefter føres slæden 22 mod venstre på figuren, hvilket får kødstykket 16 til hængende på krogen at falde ned mod stangen på juletræet 1. Som alternativ til teleskopbåndet kan der anvendes et transportbånd, der som helhed er forskydeligt frem og tilbage i 10 forhold til juletræet 1.7 DK 173832 B1 In a similar manner as shown in FIG. 1, press means shall be provided which strike or press a portion of the meat piece 16 projecting downwardly from the downstream end of the conveyor belt 16 towards the hook. Simultaneously or immediately thereafter, the carriage 22 is moved to the left of the figure, causing the meat piece 16 to hang down on the hook to fall against the bar on the Christmas tree 1. As an alternative to the telescopic belt, a conveyor belt as a whole can be moved forward and backwards. in 10 relation to the Christmas tree 1.

Når et kødstykke føres ind på transportbåndet 8 ved dets opstrøms ende, føres slæden 22 mod højre på figuren, således at kødstykket på nær den i transportretningen forreste ende er understøttet af trans-15 portbåndet. Når kødstykkets 16 forreste ende er placeret over en tom krog 8 på juletræet, føres presseorganet ned mod kødstykkets forreste del, og samtidig føres slæden 22 mod venstre set på figuren, hvorved kødstykket bringes til at hænge frit ned fra krogen 8.When a piece of meat is inserted on the conveyor belt 8 at its upstream end, the carriage 22 is guided to the right of the figure, so that the meat piece is supported by the conveyor belt near the end in the direction of transport. When the front end of the piece of meat 16 is placed over an empty hook 8 on the Christmas tree, the pressing means is brought down towards the front of the piece of meat, and at the same time the sled 22 is moved to the left as seen in the figure, thereby causing the piece of meat to hang freely from the hook 8.

20 En ny krog bringes derefter i position foran transportbåndet 5 ved hjælp af en mekanisme, der kan dreje juletræet, og den over juletræet viste mekanisme, der omfatter tre hydrauliske eller pneumatiske cylindre a, b og c, hvoraf cylinderen a har en slaglængde svarende 25 til afstanden mellem to sæt kroge og cylindrene b og c har en slaglængde på den dobbelte afstand. De tre cylindre er anbragt i serie, og ved aktivering af cylindrene enkelt- eller parvist i forskellige kombinationer kan juletræet sænkes med ethvert af krogsaette-30 ne på niveau med transportbåndet.A new hook is then brought into position in front of the conveyor belt 5 by a mechanism which can rotate the Christmas tree and the mechanism shown above the Christmas tree comprising three hydraulic or pneumatic cylinders a, b and c, of which cylinder a has a stroke corresponding to 25 to the distance between two sets of hooks and the cylinders b and c has a stroke of twice the distance. The three cylinders are arranged in series and by activating the cylinders individually or in pairs in different combinations, the Christmas tree can be lowered with any of the hook sets at the level of the conveyor belt.

Fig. 3 viser et arrangement med et vipbart transportbånd 5, der er forsynet med en tragt, der leder kødstykkets skank til en korrekt position, inden transportbåndet i en hurtig bevægelse sænkes, hvorved 35 skanken så at sige slås mod krogen 8 på juletræet 1.FIG. 3 shows an arrangement with a tiltable conveyor belt 5, which is provided with a hopper that guides the meat piece shank to a correct position before the conveyor belt is lowered in a rapid movement, so that the shank is struck against the hook 8 on the Christmas tree 1.

8 DK 173832 B18 DK 173832 B1

Arrangementet er særlig egnet ved ophængning af skinker. Det foreslås, at operatøren, som foretager den sidste tilskæring før ophængningen, orienterer skinken, så den føres frem på transportbåndet 5 med skanken 5 forrest, hvorefter tragten 31 vil foretage den endelige opretning af skinken, inden transportbåndet momentant sænkes, således at skinken presses eller slås mod krogen på juletræet og fri af transportbåndet 5. For at sikre, at krogen gennembryder sværen på kødstykket, kan 10 der monteres en fjederpåvirket arm på tragtens 31 overkant over skankens tykke ende. Eventuelt kan tragten være forsynet med en overside, som under den første del af transportbåndets vippebevægelse virker som et presseorgan, og som, efter at skinken eller 15 kødstykket af anden art har fået presset krogen ind i kødet, åbnes eller skydes til siden, hvorefter transportbåndet under den videre sænkning frigiver den del af kødstykket, som hvilede mod transportbåndet. Straks efter nedsænkningen af transportbåndet kan dette hæves 20 igen og er, efter at en ny krog er bragt i stilling foran den nedstrøms ende af båndet, klar til ophængningen af et nyt kødstykke.The arrangement is particularly suitable for hanging hams. It is suggested that the operator making the last cut before the suspension orient the ham so that it is advanced on the conveyor belt 5 with the hammer 5 first, after which the hopper 31 will make the final alignment of the ham before the conveyor belt is momentarily lowered so that the ham is pressed or is struck against the hook of the Christmas tree and free of the conveyor belt 5. To ensure that the hook pierces the cut of the piece of meat, a spring-loaded arm can be mounted on the upper edge of the hopper 31 over the thick end of the shank. Optionally, the hopper may be provided with an upper side which, during the first part of the conveyor belt's tilting movement, acts as a pressing means and which, after the ham or meat piece of another kind has pressed the hook into the meat, is opened or pushed to the side, after which the conveyor belt during the further lowering it releases the portion of the meat which rested against the conveyor belt. Immediately after the immersion of the conveyor belt, this can be raised again and, after a new hook is positioned in front of the downstream end of the belt, is ready for the suspension of a new piece of meat.

Ved denne udførelsesform for apparatet er det hensigtsmæssigt, at transportbåndet i hævet stilling 25 forløber tilnærmelsesvis vandret, så båndet ikke ved nedsænkningen kolliderer med juletræet 1 og de på dette ophængte kødstykker, medens det ved de to andre udformninger kan være hensigtsmæssigt, at transportbåndet strækker sig skråt opad, hvorved krogen på juletræet 30 normalt vil opnå en mindre indfaldsvinkel til kødstykket .In this embodiment of the apparatus, it is desirable that the conveyor belt in the raised position 25 extends approximately horizontally so that the belt does not collide with the Christmas tree 1 and the pieces of meat hung on it, while in the other two configurations it may be convenient that the conveyor belt extends. inclined upwards, whereby the hook of the Christmas tree 30 will usually achieve a smaller angle of incidence to the piece of meat.

Det skal bemærkes, at selv om apparatet her er beskrevet i forbindelse med et transportbånd 5, vil andre former for transportører, eksempelvis en rul-35 letransportør, kunne anvendes.It should be noted that although the apparatus is described herein in connection with a conveyor belt 5, other types of conveyors, for example a roller conveyor, may be used.
