Abstract

The invention relates to dividing disk shares (1) for cutting off narrow strips (4) and bars for instance to scrap or to pieces for further manufacturing (8). The cutting operation will be carried out between disk-shaped cutting tools (2 and 12). The center cutting tool (2) is fixed or rotating round a shaft (3), the others, two to four (12), are surrounding the center cutting tool (2) in an annular path. The material (4) is transversely guided into the cutting station by a guider (9). After the cutting operation the material (4) is guided ahead a determined length for cutting off by next in turn passing planetary cutting tool (12).

Description

5o2f422 2 der. Det tredje sättet är att låta två cirkuiära skivor rotera i samma plan, något åtskilda och på dessa runt perlferien placera plana saxskör med eggarnas iängdriktning tvärs skivornas plan. Sax- skären skall vara anordnade så att de möts parvis under skivornas rotation och klipper av matrialet som förs in i gapet mellan skl- vorna l dess plan. För att matrialet ej skall stoppas upp under kllppet bör skivornas periferihastighet i stort vara lika med det kllppta matrialets hastighet. Detta gör att högt ljud uppstår då saxskären i början av klippet slår emot matrialet. flatrialet som klippts av kommer ur saxen med stor hastighet och är då svårt att fånga upp utan allt för stort oväsen. Klipplöngden bestämmas huvud- sakligen av avståndet mellan saxskören runt skivorna och blir då svår att ställa om. 5o2f422 2 der. The third way is to let two circular discs rotate in the same plane, slightly separated and on these around the pearl holiday place flat scissor braces with the longitudinal direction of the edges across the plane of the discs. The scissor inserts must be arranged so that they meet in pairs during the rotation of the discs and cut off the material which is inserted into the gap between the discs in its plane. In order for the material not to be stopped under the knock, the peripheral speed of the discs should be substantially equal to the speed of the cut material. This causes a loud noise when the scissor blade strikes the material at the beginning of the clip. The cut atrial comes out of the scissors at high speed and is then difficult to catch without too much noise. The cutting length is mainly determined by the distance between the scissor grooves around the discs and then becomes difficult to adjust.

Det har blivit allt vanligare att I stallet för att upphaspia skrotrensor klippa upp dessa l lämpligt hanterbara längder för chargerlng vid omsnöltnig till ngtt matrial. Decimeterlånga längder eller daromkring är vanliga för så kallad skrottuggning. Uid andra processer där matrlalet ej utgöres av skrot utan skall klippas upp för fortsatt bearbetning måste saxarna ha hög kapacitet om man öns- kar uppkllppning av kortare bitar vid hög avverkning. linniloninam Det har nu överraskande visat sig att man kan tillverka en sax för tvärklippning av långsträckt matrial till mgcket varierande längd, med god precision, med hög produktion och med ringa buller genom att utföra kllppnlngen mellan två clrkulära saxskör där det ena skärets rotationsaxel är fixerat och låta ett antal, företrädesvis 2-4 saxskär planetariskt rotera runt detta fasta, alternativt rote- rande saxskär. Det långströckta natrlalet föree utan sldorörelse snett ln mellan det fasta skäret och det saxskär som rör sig I pia- netrörelsen och som just skall passera matrialet. Under kllppet passerar det rörliga saxskäret förbi matriaisträngen så att detta kan matas framåt en kllpplängd innan nästa rörliga saxskär kommer i klippiäge.It has become increasingly common, instead of cutting scrap cleaners, to cut up these suitably manageable lengths for charging in the event of melting to some material. Decimeter-long lengths or thereabouts are common for so-called scrap chewing. In other processes where the material does not consist of scrap but must be cut up for further processing, the scissors must have a high capacity if you want to cut up shorter pieces at high felling. linniloninam It has now surprisingly been found that it is possible to manufacture scissors for cross-cutting elongated material to very varying lengths, with good precision, with high production and with little noise by performing the cutting between two circular scissor cuts where the axis of rotation of one insert is fixed and allow a number, preferably 2-4 scissor inserts, to rotate planetary around this fixed, alternatively rotating scissor insert. The elongated natural edge precedes without sliding movement obliquely between the fixed insert and the scissor insert which moves in the piano movement and which is to pass the material. During the cut, the movable scissor insert passes the die string so that it can be fed forward a length of cut before the next movable scissor insert comes into cutting position.

Uppfinningen kommer närmare att beskrivas nedan, preciseras i ef- terföljande krav och åskådllggöras med följande figurer varvid delningssaxen visas i fig 1 framifrån, fig 2 från sidan och fig 3 uppifrån.The invention will be described in more detail below, specified in the following claims and illustrated with the following figures, the dividing shears being shown in Fig. 1 from the front, Fig. 2 from the side and Fig. 3 from the top.

För att tydligare visa några av de de roterande delarnas lagring har dessa lagringarna visats l genomskärning. a4auaaiipnlnaem Delningssaxen ,l, bggges med fördel upp på ett saxstativ ,?. På detta lagras en centrumaxel ,3. Denna kan antingen vara fast eller drivas runt av en centrumskärsmotor ,5, eventuellt via en växel och matas från elnätet via en natarkabel ,6. l ena ändan av centrum- 3 502 422 skärsaxeln ,3, monteras ett centrumskär ,2. För vissa klippsituatl- oner är det även lämpligt att centrumskärsmotorns ,5, varvtal kan varieras för att kllpphastlgheten skall fås att harmonisera med det till saxen matade matrialets ,1, ingångshastighet. Runt detta centrumskär ,2, skall i ett plan parallellt med detta rotera ett antal, företrädesvis 2-4 et, här benämnda planetskär ,l2, i start sett lika centrumskäret ,2. Planetskären ,l2, och centrumskäret ,2, skall överlappa varandra med ett sådant spel mellan varandra att matrialet ,4, som förs in i delningssaxen ,l, klippes av på sedvan- ligt sätt till avklipp ,8. Planetskären ,l2, är också lagrade på fri tapp på sidogtan av en ring ,l4, som centriskt rör sig runt centrumaxeln ,3. Denna ring ,l1, är i sin tur via ekrar ,l3, lagrad runt centrumaxeln eller på en i saxstativet ,?, fastsatt kon, vars minsta diameter är lika med eller större än centrumhålets diameter plus 2 gånger tjockaste matrialet. Ringen ,l1, drives runt av en separat planetskärsmotor ,ll, via exempelvis drivremmar ,l0, och får således planetskären ,l2, att centriskt cirkulera runt centrum- skäret ,2. Ringen ,l1, skall röra sig med rotationsriktning motsatt centrumskäret ,2. om detta är drivet. flatrialet ,4, som skall klip- pas till avklipp ,8, föres med hjälp av en fast ledaranordning ,9, snett in mellan centrumskäret ,2, och ringen ,l4, vid centrumskä- rets ,2, periferi. Uarefter ringen ,l4, vrides runt av planetskärs- motorn ,ll, kommer matrialet ,4, att klippas av mellan centrumskä- ret ,2, och det just passerande planetskäret ,l2. Efter klippet fortsätter detta planetskär ,l2, i sin bana runt centrumskäret och lämnar fri passage för matrialet ,4, att sedan åter matas fram mel- lan ringen ,l4, och centrumskäret ,2, till avsedd längd för att se- dan ånga klippas av mellan centrumskäret ,2, och det påföljande planetskäret ,l2. Om ledarröret 39, är riktat vinkelrätt mot skä- rens ,2 och 12, plan blir snlttgtan vlnkelrät mot matrialets ,4, längdriktning. Detta förorsakar dock att matrialet ,4, närmast del- ningssaxen ,l, stoppas upp temporärt vilket kan vara störande. Om man istället riktar röret något snett in mot delningssaxens ,l, in- greppsöppning blir visserligen klippgtan något vinklad mot matria- lets ,4, längdriktnlng men i stället fortsätter matrialet ,4, fram- åt även under klippet. Klipplängden bestämmes av hur långt matria- lets ,1, första ände efter föregående klipp hinner att förflgtta sig in i mellanrummet mellan ringen ,l4, och centrumskäret ,2, in- nan det fångas upp av efterföljande planetskär ,l2. Detta i sin tur beror givetvis på matrialets ,4, hastighet, antal planetskör ,l2, men framför allt ringens ,l4, rotationshastighet där rörelsen an- tingen kan vara kontinuerlig eller intermittent. Nan kan med andra ord ställa om delningssaxen ,l, för längder på avklipp ,8, från det att den kan tjänsgöra som skrottugg till avklipp av avsevärd läng- der. lbland kan det vara fördelaktigt att planetskären (l2) för att underlätta gripningen av det klippta matrialer upprätthåller en ro- tationsrörelse även mellan klippen. Detta kan ske via någon redan känd friktíonskoppling mellan dessa och centrumskäret ,(2). till 502 422 4 exempel en på centrunaküret ,2, monterad gunlekluo. Denna tongeror- planetekür-en ,l2, och dñr-lgenon för deaea att noter-o ned en not centrumskü-ret ,2, I stort sett ouereneetünonde per-lfenlhaetighet. .mvIn order to show more clearly the storage of some of the rotating parts, these bearings have been shown in section. a4auaaiipnlnaem The dividing scissors, l, are advantageously mounted on a scissor stand,?. A center shaft, 3, is mounted on this. This can either be fixed or driven around by a center cutting motor, 5, possibly via a gear unit and fed from the mains via a natural cable, 6. At one end of the center insert shaft, 3, a center insert, 2, is mounted. For certain cutting situations, it is also suitable that the speed of the center cutting motor, 5, can be varied in order to make the cutting speed harmonize with the input speed of the material fed to the scissors 1. Around this center insert, 2, in a plane parallel thereto, a number, preferably 2-4 et, here referred to as planetary insert, 12, initially seen as the center insert, 2. The planetary insert, 12, and the center insert, 2, shall overlap with each other with such a play between each other that the material, 4, which is inserted into the dividing shears, 1, is cut off in the usual manner into clippings, 8. The planetary inserts, l2, are also mounted on a free pin on the side face of a ring, l4, which moves centrally around the center axis, 3. This ring, l1, is in turn via spokes, l3, mounted around the center axis or on a cone fixed in the scissor frame,?, The smallest diameter of which is equal to or greater than the diameter of the center hole plus 2 times the thickest material. The ring, l1, is driven around by a separate planetary insert motor, l1, via, for example, drive belts, l1, and thus causes the planetary insert, l2, to circulate centrally around the center insert, 2. The ring, l1, shall move in the direction of rotation opposite the center insert, 2. if this is driven. fl the atrial, 4, to be cut into clippings, 8, is inserted by means of a fixed guide device, 9, obliquely between the center insert, 2, and the ring, 14, at the center insert, 2, periphery. After the ring, l4, is turned around by the planetary insert motor, l1, the material, 4, will be cut off between the center insert, 2, and the just passing planetary insert, l2. After the cut, this planetary insert, l2, continues in its orbit around the center insert and leaves free passage for the material, 4, to then be fed again between the ring, l4, and the center insert, 2, to the intended length so that steam is cut off. between the center insert, 2, and the subsequent planetary insert, l2. If the guide tube 39 is directed perpendicular to the inserts 2 and 12, the plane becomes perpendicular to the longitudinal direction of the material 4. However, this causes the material, 4, closest to the dividing shear, 1, to be stopped temporarily, which can be disturbing. If you instead direct the pipe slightly obliquely towards the engagement opening of the dividing scissors, l, the cutting edge is admittedly slightly angled towards the material, 4, longitudinal direction, but instead the material, 4, continues forward even below the cut. The cutting length is determined by how far the material end, 1, first end after the previous cutting has time to move into the space between the ring, l4, and the center insert, 2, before it is caught by subsequent planetary inserts, l2. This in turn depends, of course, on the speed of the material, 4, the number of planetary orbits, l2, but above all the rotational speed of the ring, l4, where the movement can be either continuous or intermittent. In other words, Nan can adjust the dividing shears, 1, for lengths of clippings, 8, from the time it can serve as scrap chews to clippings of considerable lengths. Sometimes it can be advantageous for the planetary insert (l2) to facilitate a gripping movement even between the rocks in order to facilitate the gripping of the cut material. This can be done via an already known friction coupling between these and the center insert, (2). to 502 422 4 example one on the centrunaküret, 2, mounted gunlekluo.
