Description

35 .453 373 av kniven förenkla knivens inspänningsanordning, så att ,utbyte och vändning av kniv underlättas. Detta syfte upp- nås genom att anordningen enligt uppfinningen erhållit de i de följande patentkraven angivna kännetecknen. 35 .453 373 of the knife simplify the clamping device of the knife, so that, replacement and turning of the knife is facilitated. This object is achieved in that the device according to the invention has obtained the features stated in the following claims.

Uppfinningen kommer i det följande att beskrivas när- ii samband med på ritningen visade utföringsexempel.The invention will be described in the following in connection with exemplary embodiments shown in the drawing.

Figur 1 visar ett längdsnitt genom en del av en hugg- skiva med en knivanordning enligt uppfinningen.Figure 1 shows a longitudinal section through a part of a chopping disc with a knife device according to the invention.

Figur 2 visar ett motsvarande snitt av en ändrad ut- mâTE föringsform.Figure 2 shows a corresponding section of a changed embodiment.

I figur 1 visas en huggskiva 10 med en öppning 12 för flisens passage. Huggskivan 10 är vid en av de intill öppningen 12 liggande kanterna, i figur 1 den vänstra kan- ten, försedd med en trappstegsformad urtagning 14, som är anordnad att upptaga en flisledare och en knivhållare på det sätt, som exempelvis visas i det tidigare nämnda, svenska patentet 7314475-0 (USA-patentet 4 047670). Bakom urtagningen ansluter sig en slitplât 16 anordnad ovanpå huggskivans yta på ett sätt, som likaså framgår av nämnda patent. Ett antal sådana öppningar 12, urtagningar 14 och därbakom liggande slitplâtar 16 är anordnade med jämna mel- lanrum runt huggskivans 10 omkrets.Figure 1 shows a chopping disc 10 with an opening 12 for the passage of the chips. The chopping disc 10 is provided at one of the edges adjacent to the opening 12, in Figure 1 the left edge, with a step-shaped recess 14, which is arranged to receive a chip guide and a knife holder in the manner shown, for example, in the previously mentioned , Swedish patent 7314475-0 (U.S. patent 4,047670). Behind the recess, a wear plate 16 arranged on top of the surface of the chopping board adjoins in a manner which is also apparent from the said patent. A number of such openings 12, recesses 14 and underlying wear plates 16 are arranged at regular intervals around the circumference of the chopping disc 10.

I urtagningen 14 är insatt ett fyllnadsstycke 18 som kvarhålles i urtagningen med tillhjälp av en bult 20, vil- ken är ingängad i fyllnadsstycket 18 och som på huggskivans undersida är fastdragen med tillhjälp av en mutter 22. Det- ta fyllnadsstycke 18 ersätter sålunda till större delen den tidigare flisledaren ochlufivhåflarenoch är utformat att passa i redan befintliga urtagningar 14 i huggskivan 10. Fyllnads- stycket är i sin tur i den övre, mot öppningen 12 vända de- len försedd med en urtagning 24. I denna urtagning är in- satt en minikassett bestående av en överdel 26 och en under- del 28, vilka delar 26, 28 är så utformade att de mellan sig kan upptaga en kniv, företrädesvis en vändbar kniv 30 av den typ som beskrives i det ovannämnda patentet. Vid sitt samman- satta läge då överdelen 26 och underdelen 28 i minikassetten 10 15 20 25 30 453 373 upptager kniven 30 mellan sig passar nämnda kassett i ur- tagningen 24 i fyllnadsstycket 18. Kassetten är därvid för- sedd med genomgående hål för ettuppifrån idraget fästorgan såsom en skruv 32 vilken är ingängad i fyllnadsstycket 18.Inserted in the recess 14 is a filler piece 18 which is retained in the recess with the aid of a bolt 20, which is inserted into the filler piece 18 and which is fastened on the underside of the chopping disc by means of a nut 22. This filler piece 18 thus replaces larger the part the former chip conductor ochlu fi vhå fl aren and is designed to fit in already existing recesses 14 in the chopping board 10. The filling piece is in turn in the upper part, facing the opening 12 provided with a recess 24. In this recess a mini-cassette consisting of an upper part 26 and a lower part 28, which parts 26, 28 are designed so that they can receive a knife between them, preferably a reversible knife 30 of the type described in the above-mentioned patent. In its assembled position when the upper part 26 and the lower part 28 in the mini cassette 10 15 20 25 30 453 373 receive the knife 30 between them, said cassette fits in the recess 24 in the filling piece 18. The cassette is then provided with through holes for a top view fastening means such as a screw 32 which is threaded into the filler piece 18.

I detta läge har kassettdelarna 26, 28 ett spel mellan sina horisontella ytor för att med hjälp av skruvens 32 åtdrag- ningskraft åstadkomma en klämkraft på kniven 30 som säkert fasthåller denna mellan kassettens.delar. För att förhindra att spån från de avskilda träflisstyckena skall intränga mellan gränsytorna mellan kniven 30 och kassettens under- del 28 samt mellan underdelen 28 och fyllnadsstycket 18 och mellan fyllnadsstycket 18 och huggskivan 10 är samt- liga dessa delar så anordnade att öppningens 12 bredd ökar trappstegsformigt nedåt vid varje gränsyta, som visas vid 34, 36 och 38 i figur 1. Lämpligen är även öppningen 12 koniskt ökande i nedâtriktningen för att förhindra igen- sättning.In this position the cassette parts 26, 28 have a play between their horizontal surfaces in order to provide a clamping force on the knife 30 by means of the tightening force of the screw 32 which securely holds it between the parts of the cassette. To prevent chips from the separated pieces of wood chips from penetrating between the interfaces between the knife 30 and the lower part 28 of the cassette and between the lower part 28 and the filling piece 18 and between the filling piece 18 and the chopping board 10, all these parts are arranged so that the width of the opening 12 increases stepwise. downward at each interface shown at 34, 36 and 38 in Figure 1. Preferably, the aperture 12 is also conically increasing in the downward direction to prevent clogging.

Vid den i figur 2 visade utföringsformen är de delar som är gemensamma för de båda figurerna betecknade med sam- ma hänvisningbeteckningar som i figur 1 med tillägget "a" Huggskivan 10a har en urtagning 14a med vinkelräta vä7gar.In the embodiment shown in Figure 2, the parts common to the two figures are denoted by the same reference numerals as in Figure 1 with the addition "a". The chopping disc 10a has a recess 14a with perpendicular walls.

Fyllnadsstycket l8a består av en undre del 40 som är svet- sad vid bakre delen av huggskivans 10a urtagning 14a och en övre del 42 som är fastdragen med tillhjälp av en bult 20a vilken passerar genom huggskivan till dennas undersida där bulten är fastdragen med tillhjälp av en mutter 22a. övre delen 42 av fyllnadsstycket 18a utgör knivhållare och är försedd med en upphöjning 44 vilken ingriper i en mot- svarande urtagning i kniven 30a. Bakom kniven sett i rota- tionsriktningen är knivhållaren 42 försedd med en egen slit- plåt 46. Kniven 30a och slitplåten 46 är fastdragna vid kniv- hállaren 42 från huggskivans ovansida med tillhjälp av skru- var 48, 50 så att dessa delar lätt kan bytas ut.The filler piece 18a consists of a lower part 40 which is welded to the rear part of the recess 14a of the chopping disc 10a and an upper part 42 which is tightened by means of a bolt 20a which passes through the chopping board to its underside where the bolt is tightened by means of a nut 22a. the upper part 42 of the filling piece 18a constitutes a knife holder and is provided with a ridge 44 which engages in a corresponding recess in the knife 30a. Behind the knife seen in the direction of rotation, the knife holder 42 is provided with its own wear plate 46. The knife 30a and the wear plate 46 are fastened to the knife holder 42 from the top of the chopping disc by means of screws 48, 50 so that these parts can be easily replaced out.
