Description

Foreliggende oppfinnelse angår en oppskjærsanordning for næringsmidler, især for oppskjæring pølse, spekepølse, skine, spekk, bacon, kjøtt o.l., bestående en produkttilførselsanordning med en føringsbane som strekker seg frem til et skjærplan, samt kniv som roteres og periodisk skjærer gjennom skjærplanet. The present invention relates to a slicing device for foodstuffs, in particular for slicing sausage, cured sausage, skin, lard, bacon, meat etc., consisting of a product supply device with a guideway that extends to a cutting plane, as well as a knife that is rotated and periodically cuts through the cutting plane.

Oppskjærsanordninger er kjent og har i regelen en kniv som roterer tilsvarende et planethjul, hvor kniven ved hver gjennomgang gjennom skjærplanet, utfører et snitt. Produkttilfør-selen foregår herved vanligvis diskontinuerlig, dvs. fremdriften foregår i tidsrommet mellom to på hverandre følgende snitt. Med oppskjærsanordninger av denne type kan det riktignok oppnås en høy snittfrekvens, men for å sikre en korrekt arbeidsmåte kreves en sammenlikningsvis omstendelig oppbygging av anordningen slik at de ganske betydelige krefter kan opptas på en forsvarlig måte, som oppstår ved skjæroperasjonen på grunn av kniven som roterer planetarisk. Cutting devices are known and, as a rule, have a knife which rotates corresponding to a planet wheel, where the knife makes a cut at each passage through the cutting plane. In this way, the product supply usually takes place discontinuously, i.e. the progress takes place in the time period between two consecutive cuts. With cutting devices of this type, it is true that a high cutting frequency can be achieved, but in order to ensure a correct working method, a comparatively elaborate construction of the device is required so that the fairly significant forces can be properly absorbed, which occur during the cutting operation due to the rotating knife planetary.

Det er foreliggende oppfinnelses oppgave å frembringe en oppskjærsanordning av den innledningsvis nevnte type slik at det kan oppnås høye skjærhastigheter ved liten belastning av produktet og samtidig små opptredende krefter i selve skjæren-heten, slik at det er mulig å oppnå en anordning som konstruktivt er sammenlikningsvis liten. It is the task of the present invention to produce a cutting device of the type mentioned at the outset so that high cutting speeds can be achieved with little load on the product and at the same time small acting forces in the cutting unit itself, so that it is possible to achieve a device that is structurally comparatively small.

Denne oppgave løses ifølge oppfinnelsen i det vesentlige ved at kniven via et nav er festet til en med maskinen fast opplagret drivaksel og har en diameter som langs omkretsen med samtidig kontinuerlig aksial forskyvning av skjærkanten, stiger fra en minimal verdi, kontinuerlig til en maksimal verdi og hvor produktets gjennomgangsområde bestemmes av differansen mellom den maksimale og den minimale knivradius. According to the invention, this task is essentially solved by the fact that the knife is attached via a hub to a drive shaft fixed with the machine and has a diameter which along the circumference, with simultaneous continuous axial displacement of the cutting edge, rises from a minimum value, continuously to a maximum value and where the product's passage area is determined by the difference between the maximum and the minimum blade radius.

På grunn av knivens spesielle utforming er det mulig_ å realisere høye skjærhastigheter ved kontinuerlig produkttilførsel og derved opprettholde en meget liten belastning av produktet, da kniven ikke, slik tilfellet er ved kjente utførelser, treffer produktet med slag, men i realiteten skrur seg gjennom vedkom-mende produkt og derved avskjærer den ønskede skive ved hver omdreining på nøyaktig samme måte. En vesentlig fordel er også at det på produktet ikke oppstår noen form for smøringsef f ekt ved Due to the knife's special design, it is possible_ to realize high cutting speeds with continuous product supply and thereby maintain a very small load on the product, as the knife does not, as is the case with known designs, hit the product with a blow, but in reality screws through changing product and thereby cuts off the desired disc with each revolution in exactly the same way. A significant advantage is also that no lubrication effect occurs on the product

denne skruende skjærprosess. this screw cutting process.

Kniven ifølge foreliggende oppfinnelse har fortrinnsvis på samme måte som de skiveformede kniver i kjente skjæranordning-er, en hulkile grensende til baksiden av skjærkanten slik at i praksis kun skjærkantens spiss kommer i berøring med produktet under skjærprosessen. The knife according to the present invention preferably has, in the same way as the disc-shaped knives in known cutting devices, a hollow wedge adjacent to the back of the cutting edge so that in practice only the tip of the cutting edge comes into contact with the product during the cutting process.

Ved tilsvarende utforming av knivens form kan skjæroperasjonen gjennomføres over en vinkel på minst 280°, idet det kan oppnås et tilstrekkelig stort produktgjennomføringsområde. Skivens tykkelse er på forhånd gitt av knivens skråstilling, idet skivens tykkelse retter seg etter de produktet som til enhver tid skal skjæres opp og eksempelvis kan ligge i området 1,5 til 2,5 mm. By correspondingly designing the shape of the knife, the cutting operation can be carried out over an angle of at least 280°, as a sufficiently large product penetration area can be achieved. The thickness of the disc is given in advance by the inclined position of the knife, as the thickness of the disc depends on the product that is to be cut up at any time and can, for example, be in the range of 1.5 to 2.5 mm.

Spesielt fordelaktig er det når den kniv som benyttes ifølge oppfinnelsen, består av en elastisk formbar plan skive og det benyttes et nav som har et fastspenningsanlegg tilsvarende knivens indre ringkant, som forløper tilsvarende knivens ønskede skråstilling. It is particularly advantageous when the knife used according to the invention consists of an elastically malleable flat disk and a hub is used which has a clamping system corresponding to the knife's inner ring edge, which extends corresponding to the knife's desired inclined position.

Med denne utforming er det mulig først å fremstille kniven i form av en allerede krevet omkretskontur som en plan skive og å bearbeide skjærkantens område på den krevede måte, da knivens skråning, hhv. den aksiale forskyvning som foreligger langs skjærkantens omkrets for å frembringe en skruespiral med skjærkant, først fremkommer ved fastspenning av denne knivskive på det tilsvarende utformede anlegg på navet, som dermed er fastlag på forhånd. With this design, it is possible to first produce the knife in the form of an already required circumferential contour as a flat disk and to process the area of the cutting edge in the required manner, as the slope of the knife, or the axial displacement that exists along the circumference of the cutting edge to produce a screw helix with a cutting edge, first appears when clamping this knife disc on the correspondingly designed facility on the hub, which is thus fixed in advance.

Denne utførelse forenkler fremstillingen av kniven ifølge oppfinnelsen på en ganske betydelig måte og muliggjør i tillegg uten vanskeligheter fastleggelse av ulike knivskråstil-linger ved utvelgelse av tilsvarende fastspenningsanlegg samt en enkel ettersliping av kniven da kniven med dette formål kun må løses fra navet og deretter slipes i plan tilstand. This design simplifies the manufacture of the knife according to the invention in a fairly significant way and also enables the determination of different knife bevel positions without difficulty by selecting a corresponding clamping system as well as a simple re-sharpening of the knife, as the knife for this purpose only has to be detached from the hub and then sharpened in flat state.

Ved hjelp av anordningen ifølge foreliggende oppfinnelse oppnås alltid rene snittflater uten utsmøring på grunn av snittet som samtidig trekker produktet, noe som også oppnås ved høye snitthastigheter og ved problematiske produkter. Skulle det oppstå en feil i kniven, ville denne på grunn av skjærprinsippet alltid oppstå på samme sted, noe som igjen gjør selve feilen ukritisk. With the aid of the device according to the present invention, clean cut surfaces without smearing are always achieved due to the cut which simultaneously pulls the product, which is also achieved at high cutting speeds and with problematic products. Should a fault occur in the knife, due to the cutting principle, this would always occur in the same place, which again makes the fault itself uncritical.

Det er av spesiell betydning av alle foran beskrevne fordeler kan oppnås med en anordning som utmerker seg med en ekstrem enkel oppbygging og ikke krever spesielt robuste maskinkonstruksj oner. It is of particular importance that all the advantages described above can be achieved with a device which is characterized by an extremely simple structure and does not require particularly robust machine constructions.

En utførelse av en kniv for oppskjærsanordningen ifølge oppfinnelsen er vist på tegningen viss ene figur viser et grunnriss av en slik kniv. An embodiment of a knife for the cutting device according to the invention is shown in the drawing while one figure shows a plan view of such a knife.

Kniven 3 som skal festes på en med maskinen fast opplagret drivaksel 1, festes til akselen 1 ved hjelp av en med akselen fast forbundet navdel 2. Kniven 3 har langs omkretsen en skjærkant 4, mens det til skjærkanten grensende bakre omkretsom-råde er utformet hult, slik at kun skjærkanten 4 er virksom under skjæringen. The knife 3, which is to be attached to a drive shaft 1 fixedly supported by the machine, is attached to the shaft 1 by means of a hub part 2 firmly connected to the shaft. The knife 3 has a cutting edge 4 along its circumference, while the rear circumferential area adjacent to the cutting edge is designed to be hollow , so that only the cutting edge 4 is active during cutting.

Knivens 3 radius tiltar kontinuerlig over omkretsen fra en minimal verdi nær navet til en maksimal verdi hvor de til den minimale og maksimale knivdiameter hørende radier, ligger i et radialt plan. The radius of the knife 3 increases continuously over the circumference from a minimum value near the hub to a maximum value where the radii belonging to the minimum and maximum knife diameter lie in a radial plane.

Kniven består fortrinnsvis av en elastisk formbar metallskive som på overgangsstedet fra den maksimale radius til den minimale radius er slisset radialt, slik at den ved oppspen-ningen på et fastspenningsanlegg på navdelen 2 bringes til den ønskede form tilsvarende den ønskede skråstilling av kniven 3 og fastholdes i denne stilling slik at skjærkanten 4 forløper tilsvarende en skruespiral. The knife preferably consists of an elastically malleable metal disc which is radially slotted at the point of transition from the maximum radius to the minimum radius, so that it is brought to the desired shape corresponding to the desired inclined position of the knife 3 when it is clamped on a clamping system on the hub part 2 and is retained in this position so that the cutting edge 4 extends corresponding to a screw spiral.

Denne utførelse av kniven ifølge oppfinnelsen muliggjør til tross for knivens i og for seg kompliserte romform i montert tilstand, en ytterst enkel fremstilling og gjennomføring av ukomplisert og hurtig ettersliping når kniven er demontert fra navet. This design of the knife according to the invention enables, despite the knife's inherently complicated spatial shape in the assembled state, an extremely simple manufacture and execution of uncomplicated and quick re-sharpening when the knife is dismantled from the hub.

For innstilling av ulike skivetykkelser er det fordelaktig at fastspenningsanleggets stigning kan innstilles slik at skivens tykkelse også kan endres i løpet av en skjær-operasjon. Innstilingen kan herved foregå via i forhold til hverandre forskyvbare og med styreledd med hverandre forbundne enkeltanleggsdeler. For setting different disc thicknesses, it is advantageous that the pitch of the clamping device can be set so that the thickness of the disc can also be changed during a shearing operation. The setting can thereby take place via individual plant parts that can be moved in relation to each other and are connected to each other with control joints.
