MASKINE TIL PORTIONSOPSKÆRING AF ISÆR FØDEVAREEMNERMACHINE FOR PORTION CUTTING OF PARTICULAR FOODS
Frembringelsens anvendelsesområde 5Scope of production 5
Frembringelsen angår en maskine til portionsopskæring af især fødevareemner, hvilken maskine omfatter en rotérbar skæreenhed til opskæring af emnerne, en transportør til at føre emnerne forbi skæreenheden og gennem maskinen, et op-10 tisk organ til aftastning af emnernes form og udgivelse af data om nævnte form samt en datamat, som på grundlag af de fra det optiske organ afgivne data kan styre maskinen til opskæring af emnerne i portioner med en forud fastsat vægt, længde eller en kombination deraf.The invention relates to a portion cutting machine, in particular food items, which comprises a rotatable cutting unit for cutting the articles, a conveyor for passing the articles past the cutting unit and through the machine, an optical means for scanning the form of the articles and publishing data on said items. form and a computer which, on the basis of the data supplied by the optical means, can control the machine for cutting the items into portions of a predetermined weight, length or a combination thereof.

Kendt teknikPrior art
Apparater af denne art anvendes især til opskæring af føde-20 vareemner, som enten fra naturens side eller ved produktionen har uregelmæssig form.Apparatus of this kind is especially used for cutting food items which, either by nature or by production, have an irregular shape.
Disse emner kan være fisk, især laks eller lignende fødevarer, der inden emballering skal udskæres i portioner.These items may be fish, especially salmon or similar foods, which must be cut into portions before packaging.
2525
Problemet ved opskæring af et sådant emne er, at en skæring, som udføres med ækvidistante mellemrum hen langs emnets længde, vil give uensartede portioner, idet vægten naturligvis vil være afhængig af emnets tværsnitsareal.The problem with cutting such a workpiece is that a cutting performed at equidistant intervals along the length of the workpiece will produce disparate portions, the weight of course being dependent on the workpiece cross-sectional area.
3030
Hvor der således ønskes opskæring i portioner med en forud fastlagt vægt, længde eller en kombination deraf, hvilket er særdeles ønskværdigt af hensyn til den videre distribution og salg, må opskæring ske på en sådan måde, at emnets tværsnitsareal, og dermed også vægten, registreres til bestemmelse af, hvor opskæringen skal finde sted.Where cutting is thus desired in portions of a predetermined weight, length or combination thereof, which is highly desirable for the sake of further distribution and sale, cutting must be done in such a way that the cross-sectional area of the workpiece, and thus also the weight, is recorded. to determine where the cutting should take place.
35 2 DK 96 00164 U335 2 DK 96 00164 U3
Der kendes forskellige maskiner til opskæring af emner i portioner.Various machines are known for cutting items into portions.
Til opskæring af især fiskefileter kendes fra DE, Al, 4.001.298 et apparat, som er forsynet med et antal kameraer monteret oven over og på tværs af et fremføringsbånd og med et antal rotérbare skæreknive, der ligeledes er monteret på tværs af båndet. Knivene skærer parallelt med båndets fremføringsbevægelse, og knivenes indbyrdes afstand kan varieres ved hjælp af positioneringsmidler.For cutting especially fish fillets from DE, A1, 4,001,298, an apparatus is provided which is provided with a number of cameras mounted above and across a feed belt and with a number of rotatable cutting knives also mounted across the belt. The blades cut parallel to the conveyor movement of the belt, and the spacing of the blades can be varied by positioning means.
Hver filet anbringes med sin længderetning på tværs af båndet, hvorefter filetens tværsnitsareal forskellige steder på fileten aftastes af kameraerne under båndets fremføring, hvilke kameraer giver impuls til knivenes positioneringsmidler, hvorved knivenes indbyrdes afstand indstilles til efterfølgende samtidig skæring af fiskestykker, som har ens portionsvægt.Each fillet is positioned longitudinally across the strip, after which the cross-sectional area of the fillet is scanned at different locations by the cameras during the conveying of the ribbon, which gives impetus to the positioning means of the blades, thereby adjusting the spacing of the blades for subsequent simultaneous cutting of fish pieces having equal portion weight.
Denne maskine er både dyr og besværlig i anvendelse. Dette skyldes dels de komplicerede positioneringsmidler for knivene og dels, at alle skæringer sker samtidigt. Den samtidige udlevering af flere portioner kan medføre, at én eller flere af portionerne kan være undervægtige afhængigt af filetens form og størrelse. Dette forhold komplicerer den efterfølgende emballering, som må indrettes efter denne form for opskæring.This machine is both expensive and cumbersome to use. This is partly due to the complicated positioning means for the blades and partly to the fact that all cuts occur simultaneously. The simultaneous delivery of several portions may cause one or more portions to be underweight depending on the fillet's shape and size. This relationship complicates the subsequent packaging, which must be arranged after this kind of cutting.
Endelig sætter knivenes positioneringsmidler en grænse for, hvor tæt knivene kan anbringes, og der er dermed sat en grænse for hvor små portioner eller hvor tynde skiver, der kan opskæres med apparatet.Finally, the positioning means of the blades set a limit on how tightly the blades can be placed, and thus a limit is placed on how small portions or how thin slices can be cut with the apparatus.
Fra US patentskrift nr. 4 557 019 kendes en maskine, som har en lysgiver, der kan belyse et emne med et mønster afUS Patent No. 4,557,019 discloses a machine having a light emitter that can illuminate a subject having a pattern of
3 DK 96 00164 U3 parallelle streger, som strækker sig langs med båndets fremføringsretning, hvilket mønster aftastes af et kamera, hvorefter det aftastede mønster i en datamat omsættes til oplysninger om emnets tværsnitsforhold til styring af en 5 kniv, som i en skærebevægelse bevæges i hovedsagen på tværs af båndets fremføringsretning, idet båndet under skæringen fremføres med ensartet hastighed. For at kompensere for båndets bevægelse forskydes kniven under skærebevægelsen langs med båndet og med samme hastighed som dette.3 DK 96 00164 U3 parallel lines extending along the direction of conveyance of the belt, which pattern is scanned by a camera, after which the scanned pattern in a computer is translated into information on the cross-sectional relationship of the workpiece to control a 5 knife which in a cutting motion is moved substantially across the conveying direction of the belt, during the cutting being conveyed at uniform speed. In order to compensate for the movement of the belt, the knife is moved during the cutting movement along the belt and at the same speed as this.

Til trods for denne samtidige bevægelse af både bånd og kniv fremkommer der ikke et rent snit, hvorfor snitfladerne får et udseende, som virker utiltalende på-mange brugere af det færdige produkt.Despite this simultaneous movement of both tape and knife, a clean cut does not appear, which is why the cut surfaces get an appearance that seems unattractive to many users of the finished product.

Det tekniske problem, der skal løsesThe technical problem to be solved
Det er formålet med frembringelsen at angive en udformning 20 af en maskine af den omhandlede art, så maskinen med en stationært anbragt skæreenhed uafhængigt af emnernes form altid frembringer portioner, der har samme vægt, længde eller en kombination deraf, og har et stort fladeareal med et rent og tiltalende snit uden flossede kanter.It is the object of the invention to specify a design 20 of a machine of the kind in question, so that the machine with a stationary cutting unit, independent of the shape of the workpieces, always produces portions having the same weight, length or a combination thereof, and having a large surface area with a clean and appealing cut without frayed edges.
2525
Den nye teknikThe new technique
Dette formål opnås med udgangspunkt i en maskine af den i 30 indledningen angivne art, hvilken maskine ifølge frembringelsen er ny ved, at skæreenheden har en om en første aksel rotérbar kniv, hvis æg strækker sig radialt fra nævnte første aksel, der er anbragt parallelt med transportørens længderetning, og at skæreenheden kan vippes om en anden aksel, som er parallel med transportørens overflade på tværs af dennes længderetning.This object is achieved on the basis of a machine of the kind specified in the preamble, which machine according to the invention is new in that the cutting unit has a knife rotatable about a first shaft, the eggs of which extend radially from said first shaft arranged parallel to the longitudinal direction of the conveyor and that the cutting unit can be tilted about another shaft which is parallel to the surface of the conveyor transversely of its longitudinal direction.

Den tekniske virkningThe technical impact
Ved at anvende den ovenfor nævnte nye teknik i forbindelse med den kendte teknik kan maskinen på grund af den store hastighed for en kniv i skæreenheden udskære portioner med et rent snit, så der ikke fremkommer flossede kanter på emnet eller portionerne. Portionerne kan også udskæres meget tyndt, når skæreenheden ved hjælp af den anden aksel vippes i forhold til emnet, så de enkelte snit kan lægges meget tæt efter det foregående snit, for eksempel ned til ca. 10 mm. Ved skråstillingen af skæreenheden fås også et stort areal af de enkelte portioners snitflader, hvilket giver et smukt og tiltalende udseende af portionerne, idet det får den enkelte portion til at syne større end en portion, som med tilsvarende vægt, længde eller en kombination deraf er udskåret ved snit, der er vinkelret på portionens plan.By using the above-mentioned new technique in conjunction with the prior art, the machine can cut portions with a clean cut due to the high speed of a knife in the cutting unit so that no frayed edges appear on the workpiece or portions. The portions can also be cut very thin when the cutting unit is tilted relative to the workpiece by means of the second shaft, so that the individual sections can be placed very close to the previous cut, for example down to approx. 10 mm. When cutting the cutting unit, a large area of the cut portions of the individual portions is also obtained, which gives a beautiful and appealing appearance of the portions, making the individual portion appear larger than a portion which is of similar weight, length or a combination thereof. cut by cuts perpendicular to the portion plane.
Ved, som omhandlet i krav 2, at skæreenheden i forhold til den anden aksel kan vippes en hældningsvinkel a, som for eksempel ligger mellem 0° og 45°, kan snitfladernes areal tilpasses eller varieres på en enkel måde.By referring to claim 2, that the cutting unit relative to the second shaft can be tilted at an angle of inclination α, which is, for example, between 0 ° and 45 °, the area of the cutting surfaces can be adjusted or varied in a simple way.
Ved, som angivet i krav 3, under vedvarende bevægelse af transportøren at føre kniven fra en udgangsstilling modsat emnet og accelerere den i sit skæreplan, når en skæreposition i emnet er ud for kniven, gennemskæres emnet med høj hastighed ved en nærmest slagagtig bevægelse til opnåelse af et rent snit, hvorefter kniven igen bremses og standser i sin udgangsstilling. Dette skyldes, at kniven føres gennem det enkelte emne på den skæreteknisk mest hensigtsmæssige måde, nemlig i hovedsagen parallelt med transportørens overside.As stated in claim 3, during continuous movement of the conveyor, to guide the knife from a starting position opposite the workpiece and accelerate it in its cutting plane when a cutting position in the workpiece is next to the knife, the workpiece is cut at high speed by a near-stroke movement to achieve of a clean cut, after which the knife again brakes and stops in its initial position. This is because the knife is passed through the individual workpiece in the most convenient way, namely in the main parallel to the top of the conveyor.
Ved visse med et skind forsynede emner, for eksempel fiskekød med skind, er fordelagtigt som angivet i krav 4, at 5 DK 96 00164 U3 knivens æg er savtakket, idet savtænderne bryder skindets overflade, så skindet ikke mases ned i kødet og ødelægger dette.For certain leather-provided items, for example, fish meat with skin, it is advantageous as claimed in claim 4 that the eggs of the knife are sawed, as the saw teeth break the surface of the skin so that the skin is not ground into the meat and destroys it.
5 Med fordel omfatter transportøren, som omhandlet i krav 5, et første bånd, som i forhold til emnernes fremføringsretning er anbragt forud for skæreenheden, samt et efter skæreenheden anbragt andet bånd, der bevæges med samme hastighed som det første bånd. Herved kan skæreenhedens kniv fø-10 res gennem mellemrummet mellem de to bånd og under transportørens overflade til fuldstændig overskæring af emnerne.Advantageously, the conveyor as defined in claim 5 comprises a first belt positioned in front of the cutting unit prior to the cutting unit as well as a second belt located after the cutting unit moving at the same speed as the first belt. This allows the cutting unit's knife to be passed through the space between the two bands and under the surface of the conveyor to completely cut the blanks.
For, som omhandlet i krav 6, at fastholde de enkelte emner effektivt under skæringen kan maskinen oven over det første 15 bånd og umiddelbart foran kniven have en holder, der kan indgribe med et emne under dettes skæring.In order to maintain the individual items effectively during the cutting, as claimed in claim 6, the machine may have a holder which can engage with a workpiece during its cutting, above the first strip and immediately in front of the knife.
Holderen kan, som omhandlet i krav 7, være passiv eller aktiv.The holder may, as claimed in claim 7, be passive or active.

Beskrivelse af udførelseseksempler På tegningen er vist en maskine 1 ifølge opfindelsen til portionsvis opskæring af fødevareemner, såsom laks og lignende emner.Description of Embodiments The drawing shows a machine 1 according to the invention for portion cutting of food items, such as salmon and similar items.
Maskinen 1 er opbygget på et på tegningen ikke vist stel med ben, så maskinen kan opstilles og tages i brug som en selvstændig produktionsenhed i et opskærings- og pakkeanlæg .The machine 1 is built on a frame not shown in the drawing with legs, so that the machine can be set up and used as an independent production unit in a cutting and packing plant.
Til fremføring af emner 2, som skal opskæres i portioner i maskinen 1, har maskinen en transportør, der omfatter et første bånd 3 og et andet bånd 4, hvilket første bånd 3 strækker sig fra maskinens 1 indføringsende og hen til en skærezone i form af en skæreenhed 5, og hvilket andet bånd 4 strækker sig fra skæreenheden 5 i forlængelse af det første bånd 3 og hen til maskinens afgangsende.For conveying blanks 2 to be cut into portions in the machine 1, the machine has a conveyor comprising a first belt 3 and a second belt 4, said first belt 3 extending from the insertion end of the machine 1 to a cutting zone in the form of a cutting unit 5, and the second belt 4 extending from the cutting unit 5 in extension of the first belt 3 and towards the exit end of the machine.
Det første bånd 3 forløber på kendt måde over en skarp kant ved skæreenheden 5 samt over venderuller, hvoraf den ene 6 er en drevet rulle til bevægelse af båndet, så båndets 3 overside som vist ved pilen 7 bevæges i retning fra indgangsenden og mod skæreenheden 5.The first belt 3 extends in a known manner over a sharp edge at the cutting unit 5 as well as over rollers, one of which is a driven roller for moving the belt, so that the upper side of the belt 3 as shown by the arrow 7 moves in the direction from the input end and towards the cutting unit 5. .
Skæreenheden 5 er opbygget med en rotérbar kniv 10, der er fastgjort til enden af en første aksel 11, som er lejret i et lejehus 12. Kniven 10 strækker sig radialt ud fra akslen 11.The cutting unit 5 is constructed with a rotatable knife 10 attached to the end of a first shaft 11 which is mounted in a bearing housing 12. The knife 10 extends radially from the shaft 11.
Lejehuset 12 er forskudt til siden i forhold til transportøren på en sådan måde, at akslen 11 tilnærmelsesvis ligger i plan med transportørens overside, idet det tilstræbes, at knivens 10 æg under skæringen af emnet 2 strækker sig i ho-The bearing housing 12 is displaced laterally with respect to the conveyor in such a way that the shaft 11 is approximately flush with the top of the conveyor, with the aim that the eggs 10 of the knife 10 extend during the cutting of the workpiece 2 in the head.
7 DK 96 00164 U3 vedsagen vandret i midten af emnet 2.7 DK 96 00164 U3 saw horizontal in the center of the workpiece 2.
De mod hinanden vendende ender af de to bånd 3, 4 må have indbyrdes afstand, så kniven 10 kan trænge så langt igennem 5 emnerne 2 under skæringen, at disse kan gennemskæres fuld stændigt.The opposite ends of the two strips 3, 4 must be spaced apart so that the knife 10 can penetrate so far through the workpieces 2 during the cutting that they can be cut through completely.
Kniven 10 har en udgangsstilling modsat emnernes 2 position på båndet 3, i hvilken stilling kniven 10 står stille. Ved 10 aktivering accelereres kniven 10 og bevæger sig rundt i sit skæreplan, hvorunder den krydser transportøren med båndene 3, 4. Efter at have passeret båndene 3, 4 bremses kniven 10 igen og standser i sin udgangsstilling efter gennemløb af en hel omdrejning, hvor den forbliver indtil næste skæring. 15The knife 10 has an initial position opposite the position of the blanks 2 on the belt 3, in which position the knife 10 is stationary. At 10 activation, the knife 10 accelerates and moves around its cutting plane, under which it traverses the conveyor with the belts 3, 4. After passing the belts 3, 4, the knife 10 is again braked and stops in its initial position after going through a full rotation where it stays until the next cut. 15
Til styring af kniven 10 findes langs periferien af dens skæreplan en styrering 18, der for eksempel består af to indbyrdes forbundne ringe af et passende materiale, såsom nylon, hvilke ringe er anbragt med en ring på hver side af 20 knivens 10 skæreplan.For guiding the knife 10, along the periphery of its cutting plane there is a guide ring 18 consisting, for example, of two interconnected rings of a suitable material, such as nylon, which rings are provided with a ring on each side of the cutting plane of the knife 10.
Tilsvarende er det andet bånd 4 ført og drevet over en skarp kant samt over venderuller, hvoraf den ene 8 er en drevet rulle til bevægelse af båndet, så båndets 4 overside 25 bevæges videre fra skæreenheden 5 og mod afgangsenden, som vist ved pilen 9.Similarly, the second belt 4 is guided and driven over a sharp edge as well as over rollers, one of which 8 is a driven roller for moving the belt so that the upper side 25 of the belt 4 is moved further from the cutting unit 5 and towards the outlet end, as shown by arrow 9.
Det første bånds 3 drivrulle 6 er drevet kontinuerligt af en motor 14, og på enden af drivrullen findes en snorskive 30 15. Over snorskiven 15 og en tilsvarende snorskive 17 på det andet bånds 4 drivrulle 8 løber en endeløs rem 16. Båndene 3, 4 skal bevæges synkront, hvilket sikres med lige store diametre på snorskiverne 15, 17 og ved at remmen 16 for eksempel er en tandrem.The drive belt 6 of the first belt 3 is driven continuously by a motor 14 and at the end of the drive roller there is a pulley 30 15. Above the pulley 15 and a corresponding pulley 17 on the drive belt 8 of the second belt 4 runs an endless belt 16. The belts 3, 4 must be moved synchronously, which is ensured with equal diameters on the string discs 15, 17 and by the strap 16 being, for example, a toothed belt.
Til aftastning af båndenes 3, 4 bevægelse er der ved en af 35 8 DK 96 00164 U3 venderullerne eller i motoren 14 anbragt en på tegningen ikke vist impulsgiver, som registrerer båndenes 3, 4, og dermed også et på det enkelte bånd placeret emnes 2, fremføringsbevægelse i forhold til skærezonen.For sensing the movement of the belts 3, 4, one of the impulse transducers not shown in the drawing, which detects the belts 3, 4, is placed on one of the turning rollers or in the motor 14, and thus also a blank 2 placed on the individual belt. , advance movement relative to the cutting zone.

Oven over det første bånd 3 er der mellem indgangsenden og skæreenheden 5 monteret et iøvrigt almindeligt kendt optisk organ i form af en laser 19, som kan af taste oversiden af båndet 3 på tværs af båndets længderetning, hvorved laseren 10 19 kan måle højden af den opragende del et emne 2, der lig ger på båndets overside.Above the first band 3 there is mounted between the input end and the cutting unit 5 an otherwise well-known optical means in the form of a laser 19, which can sense the upper side of the band 3 across the longitudinal direction of the band, whereby the laser 10 19 can measure the height of the projecting part a blank 2 lying on the top of the tape.
Denne aftastning kan foretages ved hjælp af en enkelt laser 19, som af en reciprocerende og på tegningen ikke nærmere 15 angivet linearmotor bevæges hen og tilbage tværs over emnet 2, når dette føres under laseren 11 på båndet 3. Laseren 11 giver data om emnets 2 højde over båndet 3 eller tykkelse for hver gang, der foretages en aftastning, og på grundlag af stedet for laserens 19 reciprocerende bevægelse på tværs 20 af båndet, hvor aftastningen er foretaget, kan en datamat ud fra en given densitet for emnet beregne tværsnitsarealet og dermed vægten af den del af emnet, som på et givet tidspunkt er blevet aftastet. Datamaten er efter opmåling af hele emnet 2 herefter i stand til at starte kniven 10, når 25 båndet 3 under vedvarende bevægelse fremfører emnet 2 så langt, at en efterfølgende afskæring netop giver en portion, som har den forud fastsatte vægt, længde eller en kombination deraf.This scanning can be done by means of a single laser 19 which is moved back and forth across the blank 2 by a reciprocating and in the drawing not further specified 15, as it is passed under the laser 11 on the tape 3. The laser 11 gives data on the blank 2 of the blank. height of the band 3 or thickness for each time a scan is made, and based on the location of the reciprocating movement of laser 19 across the band where the scan is made, a computer can calculate the cross-sectional area from a given density for the workpiece, and thus the weight of the part of the subject which has been scanned at a given time. The computer, after measuring the entire workpiece 2, is then able to start the knife 10, when the belt 3 advances the workpiece 2 in continuous motion so far that a subsequent cutting precisely gives a portion having the predetermined weight, length or a combination. thereof.
30 Ved emner 2, der for eksempel har et rundt tværsnit, så emnets kontur kan skygge for aftastningen, kan der være anbragt en yderligere laser, som kan aftaste emnet 2 fra dettes ende til frembringelse af et entydigt billede af det pågældende emnes form.For objects 2 having, for example, a circular cross-section, so that the workpiece's contour can shade the scan, an additional laser may be provided which can scan workpiece 2 from its end to produce a clear picture of the shape of the workpiece in question.
35 Når den ønskede position af emnet 2 på båndet 3 er ved at 9 DK 96 00164 U3 være nået, aktiveres skæreenheden 5 til gennemskæring af emnet 2.When the desired position of the workpiece 2 on the tape 3 is reached, the cutting unit 5 for cutting the workpiece 2 is activated.
Lejehuset 12 er styret i på tegningen ikke viste holdeorganer, så lejehuset 12 med akslen 11 og kniven 10 kan vippes om en anden aksel 13, der strækker sig tilnærmelsesvis parallelt med båndets 3 overflade og på tværs af dettes længderetning 7.The bearing housing 12 is guided in holding means not shown in the drawing, so that the bearing housing 12 with the shaft 11 and the knife 10 can be tilted about another shaft 13 extending approximately parallel to the surface of the belt 3 and transversely of its longitudinal direction 7.
Ved vipning af lejehuset 12 om den anden aksel 13 kan knivens 10 skæreplan ændres fra at være rettet vinkelret mod båndets 3 overflade og til at hælde en vinkel a i forhold til overfladen, hvilken vinkel a fortrinsvis ligger mellem 0° og 45°.By tilting the bearing housing 12 about the second shaft 13, the cutting plane of the knife 10 can be changed from being perpendicular to the surface of the belt 3 and to inclining an angle α relative to the surface, which angle a is preferably between 0 ° and 45 °.
Det er indlysende, at ved stillingen, hvor knivens 10 skæreplan er vinkelret mod båndets 3 overflade, vil der af emnet 2 blive afskåret portioner, hvis tykkelse eller længde alene afhænger af det stykke, som båndet 3 er bevæget fremad af datamaten siden det forudgående snit. Portionernes fladeareal vil samtidig svare til emnets tværsnitsareal på det pågældende sted af emnet 2.It is obvious that at the position where the cutting plane of the knife 10 is perpendicular to the surface of the tape 3, portions 2 will be cut off, the thickness or length of which depends solely on the piece on which the tape 3 is moved forward by the computer since the previous cut . The area of the portions will at the same time correspond to the cross-sectional area of the workpiece at that point of the workpiece 2.
Hælder knivens 10 skæreplan derimod i forhold til båndets 3 overflade, vil portionernes tykkelse eller længde afhænge ikke alene af båndets 3 bevægelse siden det forudgående snit, men også af hældningsvinklens α størrelse, og det vil forstås, at portionernes fladeareal med voksende hældningsvinkel a vil forøges i forhold til emnets tværsnitsareal på det pågældende sted af emnet 2, og dette fladeareal vil være størst, når hældningsvinklen α er størst, for eksempel er 45°.On the other hand, if the cutting plane of the knife 10 inclines with respect to the surface of the belt 3, the thickness or length of the portions will depend not only on the movement of the belt 3 since the previous cut, but also on the size of the angle of inclination, and it will be understood that the surface area of the portions with increasing inclination angle α will be increased. relative to the cross-sectional area of the workpiece at that particular site of workpiece 2, and this surface area will be greatest when the angle of inclination α is greatest, for example 45 °.
Ved en fast indstillet skærevinkel α, som fortrinsvis er 45°, startes kniven 10 på sådanne tidspunkter under båndenes 3, 4 vedvarende bevægelse, at de enkelte portioner al- 10 DK 96 00164 U3 tid opnår en forud fastsat vægt.At a fixed cutting angle α, which is preferably 45 °, the knife 10 is started at such times during the continuous movement of the belts 3, 4 that the individual portions of all time achieve a predetermined weight.
Det vil også forstås, at portionernes tykkelse eller længde aftager ved tiltagende hældningsvinkel, når båndet 3 iøv-rigt fremføres med ensartet hastighed, så det er muligt af datamaten at beregne og indstille hældningsvinklen a på baggrund af emnets 2 tværsnitsareal til opnåelse af et forud fastsat fladeareal og tykkelse og dermed også en forud fastsat vægt for de enkelte portioner.It will also be appreciated that the thickness or length of the portions decreases with increasing inclination angle as the belt 3 is otherwise advanced at uniform speed, so that it is possible for the computer to calculate and adjust the angle of inclination a based on the cross-sectional area of the blank 2 to obtain a predetermined surface area and thickness and thus also a predetermined weight for the individual portions.
For at sikre fastholdelse af emnerne 2 under deres skæring kan der oven over det første bånd 3 og umiddelbart foran kniven 10 være anbragt en holder, der ikke er vist på tegningen, hvilken holder ved hjælp af en i den ene ende hængslet arm kan bringes i indgreb med emnerne 2. Armen aktiveres på kendt måde af et kraftorgan, som på sin side aktiveres af datamaten, når et emne 2 er under opskæring.To ensure retention of the blanks 2 during their cutting, a holder not shown in the drawing may be placed above the first band 3 and immediately in front of the knife 10, which holder can be brought into place by means of an arm hinged at one end. engagement with the blanks 2. The arm is actuated in a known manner by a force member, which in turn is activated by the computer when a blend 2 is under cutting.
Holderen kan være en passiv holder, der for eksempel ved sin vægt eller ved fjederkraft presser emnerne 2 ned mod båndet 3 under knivens 10 skæring gennem det enkelte emne. Holderen kan imidlertid også være aktiv i form af en med pigge forsynet rem, som bevæges synkront med båndet 3, idet piggene griber ind i oversiden af det enkelte emne 2.The holder may be a passive holder which, for example by its weight or by spring force, pushes the blanks 2 down against the belt 3 during the cutting of the knife 10 through the individual blanks. However, the holder may also be active in the form of a studded strap which moves synchronously with the strap 3, the studs engaging the upper side of the individual blank 2.
Maskinens virkemådeOperation of the machine
Maskinens virkemåde vil herefter blive beskrevet ved et eksempel .The operation of the machine will then be described by way of example.
Før opstart af maskinen 1 indstilles datamaten til at opskære for eksempel en lakseside i portioner af x gram eller med en bestemt længde eller en kombination deraf. Båndet 3 og skæreenheden 5 startes op, hvorefter emnerne 2 anbringes på langs af båndet 3. Under det enkelte emnes 2 passage hen 11 DK 96 00164 U3 under laseren 19 måles dets tværsnitsareal i et antal gange langs emnet til opmåling af hele emnet og dettes form.Before starting the machine 1, the computer is set to cut, for example, a salmon side into portions of x grams or with a specific length or combination thereof. The belt 3 and the cutting unit 5 are started up, after which the blanks 2 are placed longitudinally of the belt 3. During the passage of the individual blanks 11 under the laser 19, its cross-sectional area is measured a number of times along the blank to measure the entire blank and its shape. .
De målte data fra laseren 19 føres til datamaten, som på grundlag af de målte data for emnernes 2 tykkelse og bredde samt en forud fastsat densitet for emnerne 2 fortløbende beregner vægten af hele emnet 2 samt bestemmer, hvornår kniven 10 skal aktiveres, og bestemmer hældningsvinklen a, for at en forud fastsat portion af et emne 2 netop vil være ud for kniven 10.The measured data from the laser 19 is fed to the computer which, on the basis of the measured data for the thickness and width of the blanks 2 and a predetermined density for the blanks 2, continuously calculates the weight of the whole blank 2 and determines when the knife 10 is to be activated and determines the angle of inclination a, so that a predetermined portion of a blank 2 will be just off the knife 10.
Når det pågældende emne 2 er udfor knivens 10 skæreplan, sættes kniven 10 i bevægelse fra sin udgangsstilling modsat emnet 2 og accelereres, så kniven 10 ved emnet 2 har sin maksimale hastighed under skæringen i emnet. Derefter bremses kniven 10 påny og ender i sin udgangsstilling.When the workpiece 2 is off the cutting plane of the knife 10, the knife 10 moves from its starting position opposite the workpiece 2 and accelerates so that the knife 10 at the workpiece 2 has its maximum speed during the cutting of the workpiece. Then, the knife 10 is again braked and ends in its initial position.
Ved knivens 10 bevægelse i skæreplanet afskæres en portion af emnet 2 med netop den ønskede vægt på x gram eller længde.As the knife 10 moves in the cutting plane, a portion of the workpiece 2 is cut with precisely the desired weight of x grams or length.
Medens kniven 10 fortsætter sin rundtgående bevægelse hen til sin udgangsstilling, bevæges båndet 3 og den resterende del af emnet 2 videre til en ny position, så kniven 10 ved sin næste opstart passerer båndet 3 og gennemskærer det fremførte emne 2 netop der, hvor det næste afskårne stykke vil have vægten x gram eller længde.As the knife 10 continues its circumferential movement to its initial position, the belt 3 and the remaining portion of the workpiece 2 are moved to a new position, so that at its next start, the knife 10 passes the belt 3 and intersects the advanced workpiece 2 precisely where the next cut piece will have weight x grams or length.
Ved hjælp af apparatet ifølge frembringelsen kan man således opnå enhver ønsket portionsvægt også ved meget tyndt udskårne portioner ved hjælp af en enkel og driftsikker konstruktion, som tillige let lader sig betjene og vedligeholde, ligesom dens arbejdssikkerhed er høj.Thus, by means of the apparatus according to the invention, any desired portion weight can be obtained even at very thinly cut portions by means of a simple and reliable construction, which is also easily serviceable and maintained, and its working safety is high.
