Anordning för att kapa en mineralullsbana Föreliggande uppfinning avser en anordning för att kapa en mineralullsbana, vilken anordning uppvisar ett pä 5 tvären Over mineralullsbanan sig sträckande och genom mi-neralullsbanan emot dennas plan rörligt, icke roterande kapbett.The present invention relates to a device for cutting a mineral wool web which has a transversely extending over the mineral wool web extending and moving through the mineral wool web against its plane, non-rotating cutting bed.

Vid tillverkning av mineralull sker direkt pä pro-duktionslinjen en formatskärning, vanligen med cirkelsägar 10 som har ett härdmetallskär som fräser bort ca 4 mm av pro-dukten och som bildar damm, vilket skall avsugas. Vid en linjebredd om 2 m och en delning till skivor om 0,5 x 1,0 mm skär man bort 1,5 % av produktionen, varvid uppstär ca 50 kg/h damm. Av denna mängd härrör sig 30-60 % frän tvär-15 kapningen beroende pä om man skär formatet tvärs linjen i 1,0 mm eller 0,5 mm längder.In the production of mineral wool, a format cut is made directly on the production line, usually with circular saws 10 having a core metal cutter which cuts away about 4 mm of the product and which forms dust, which is to be sucked off. At a line width of 2 m and a division into slices of 0.5 x 1.0 mm, 1.5% of the production is cut, whereby about 50 kg / h of dust is raised. Of this amount, 30-60% is derived from the cross-cutting, depending on the cut across the line in 1.0 mm or 0.5 mm lengths.

En dammfri längsdelning kan ästadkommas t.ex. med bandknivar (bandsägar med knivslipade bett) eller längsamt roterande härdmetallskärbett med knivslipning enligt fins-20 ka patentet nr 56636 eller en cirkelrund knivslipad klinga av den typ som används inom textilindustrin.A dust-free longitudinal division can be achieved e.g. with band knives (band saws with knife-sharpened bites) or slow-rotating cemented-metal scissors with knife-grinding according to Finnish Patent No. 56636 or a circular knife-sharpened blade of the type used in the textile industry.

För tvärkapning finns samma längsamt roterande cir-kelkniv tillämpad, men utrustningen är dyr med en avance-rad datorstyrning av likströmsmotorer som accelerar och 25 retarderar samt reverserar klingan för rotation och gäng i avsedd riktning.For cross-cutting, the same slowly rotating circular knife is used, but the equipment is expensive with an advanced computer control of DC motors that accelerate and decelerate and reverse the blade for rotation and thread in the intended direction.

För att dessa roterande klingor skall skära lätt genom ullbanan bör de vara tunna, vilket medför att de lätt börjar kasta.In order for these rotating blades to cut easily through the wool web, they should be thin, which means that they easily start to throw.

30 För dammfri tvärkapning används även snabbtsläende giljotiner med tandade bett som vertikalt slär genom ullbanan. Giljotinbettet, som gör ett slag pä ca 0,1 s, ut-sättes under slaget för ett tryck frän den kontinuerligt frammatande ullbanan. Bettet mäste därför vara minst 5 mm 35 tjockt. En sädan giljotin kan inte kapa produkter med hög- 2 80622 re densitet än ca 80 kg/m3 p.g.a. ovannämnda olägenhet. ΡΔ grund av nämnda tryck mot giljotinbettet blir ävän skäret ojämnt och ullbanan uppvisar of ta en spjälkning i skär-snittet.For dust-free cross-cutting, quick-wielding guillotines with toothed bites are also used that vertically cut through the wool web. The guillotine bed, which makes a stroke of about 0.1 s, is subjected to a pressure from the continuously advancing wool web during the stroke. The bite must therefore be at least 5 mm thick. Such a guillotine cannot cut products with a higher density than about 80 kg / m3 p.g.a. the aforementioned inconvenience. ΡΔ due to said pressure on the guillotine bed, the cutting also becomes uneven and the wool web often exhibits a splitting in the cutting section.

5 NO-patentskriften 12919, US-patentskriften 3 537 351 ja GB-ansökningsskriften 2 000 711 beskriver skäranordningar för papper och liknande.NO patent 12919, US patent 3,537,351 and GB application 2,000 711 disclose cutting devices for paper and the like.

Ändamälet med föreliggande uppflnning Sr att ut-gäende frän känd giljotinkapning av mineralull ästadkomma 10 en ny anordning, som förmär utföra dammfri kapning av en mineralullsbana utan att vara behäftad med kända giljoti-ners olägenheter.The object of the present invention is to provide a new device which emits dust-free cutting of a mineral wool web without the inconvenience of known guillotines, from the point of view of known guillotine cutting of mineral wool.

Anordningen enligt uppflnningen, av inledningsvls definierad typ, är i huvudsak kännetecknad av 15 att kapbettet utgöres av ett tunt och icke spänbil- dande skärblad, att skärbladet är inspänt i en ram för säkerstäl-lande av sträckt skäregg under kapnlngen, att ramen med Inspänt skärblad är anordnad att sam-20 tidigt röra sig vertikalt emot mineralullsbanan och hori-sontellt pä tvären över denna 1 av en sned kapningsrörel-se, och att ramen med inspänt skärblad är monterad pä en vagn anordnad att under kapnlngen av mineralullsbanan röra 25 sig synkront med denna.The device according to the invention, of the type defined by the preamble, is characterized mainly by the fact that the cutting bit is a thin and non-tensioning cutting blade, that the cutting blade is clamped in a frame for securing stretched cutting edges during the cutting, that the frame with tensioned cutting blade is arranged to simultaneously move vertically against the mineral wool web and horizontally across it 1 by an oblique cutting movement, and that the frame with clamped cutting blade is mounted on a carriage arranged to move synchronously with the cutting of the mineral wool web. this.

Företrädesvis är den sneda skärkapningens horison-talrörelse anordnad lika stor eller större än vertikal-rörelsen, varigenom man säkerställer ett snitt av god kva-litet. En vinkel ungefär 30° relativt horisontalplanet tor-30 de kunna anses vara optimal för att fä ett bra snitt med liten kraft och snabb skärrörelse. Olika lösningar för att ästadkomma en dylik skärrörelse är närmare angivna i pa-tentkraven 7 och 8.Preferably, the horizontal movement of the oblique cutting is arranged equal to or greater than the vertical movement, thereby ensuring a cut of good quality. An angle of about 30 ° relative to the horizontal plane can be considered optimal for obtaining a good cut with low force and fast cutting motion. Various solutions for effecting such a cutting movement are specified in patent claims 7 and 8.

Genom att skärbladet är utformat tunt, företrädes-35 vis med en tjocklek av högst ungefär 3 mm, blir skärkraf- 3 80622 ten väsentligt mindre än för de tjockare kaphingsbett, som användes i kända giljotiner och i roterande skärklingor.Because the cutting blade is formed thin, preferably with a thickness of no more than about 3 mm, the cutting force becomes substantially smaller than for the thicker cutting bites used in known guillotines and in rotary cutting blades.

Genom att det tunna skärbladet är sträckt i en ram kan man uppnä ett rakt skärsnitt över hela skärlängden 5 även vid sä Stora längder som upp tili 3 m. Ramen för in-spänning av skärbladet kan utföras som en lätt rörkonst-ruktion, t.ex. som en triangelbom, varvid den rörliga massan blir liten, och den fram- och ätergäende rörelsen utan svärigheter fds snabb. Tack väre den jämfört med kända 10 anordningar läga vikten, erforderliga stöd- och styrkon-struktioner inbegripna, uppnär man Stora inbesparingar dels rent tillverkningsmässigt och dels genom lättare ut-förbara servicearbeten.Because the thin cutting blade is stretched in a frame, a straight cut across the entire cutting length 5 can be obtained even at large lengths up to 3 m. The frame for clamping the cutting blade can be made as a light tube construction, e.g. . like a triangle boom, whereby the moving mass becomes small, and the reciprocating motion without difficulty gets fast. Thanks to the low weight, including the necessary support and control structures, compared with known devices, large savings are achieved both purely in terms of production and partly through more easily serviceable work.

Vagnens synkrona rörelse med mineralullsbanan under 15 skärförloppet kan exempelvis ästadkommas medelst servomo-tormanövrerade draglinor eller mutterskruv-drift.The synchronous movement of the trolley with the mineral wool web during the cutting process can, for example, be achieved by servomotor operated traction lines or nut screw operation.

Uppfinningen skall i det följande beskrivas mer de-taljerat under hänvisning tili bifogade schematiska rit-ning.The invention will be described in greater detail below with reference to the accompanying schematic drawings.

20 Figurerna 1-3 visar ett första utföringsexempel av anordningen, sedd i snitt mot mineralullsbanans rörelse-riktning, uppifrän respektive i riktning A enligt figur 2.Figures 1-3 show a first embodiment of the device, seen in section with the direction of movement of the mineral wool web, from above and in direction A of Figure 2, respectively.

Figurerna 4-6 visar pä samma sätt ett andra utföringsexempel av anordningen.Figures 4-6 similarly show a second embodiment of the device.

25 Figur 7 visar i större skala en del av skärbladet.Figure 7 shows on a larger scale part of the cutting blade.

Mineralullsbanan som skall kapas är synlig pä rit-ningsfigurerna 1 och 4, och är betecknad med hänvisnings-siffran 1. Mineralullsbanans 1 rörelseriktning är i figurerna 1 och 4 emot den som betraktar ritningen. I figurer-30 ne 2 och 5 är mineralullsbanans rörelseriktning uppifrän nedät, i figur 3 frän vänster mot höger och i figur 6 frän höger mot vänster; mineralullsbanan är inte synlig i dessa figurer.The mineral wool web to be cut is visible on the drawing figures 1 and 4, and is indicated by the reference numeral 1. The direction of movement of the mineral wool web 1 in figures 1 and 4 is opposite to that of the drawing. In Figures 2 and 5, the direction of movement of the mineral wool is top down from below, in Figure 3 from left to right and in Figure 6 from right to left; the mineral wool web is not visible in these figures.

Kapningsanordningen är allmänt betecknad med hän-35 visningssiffra 2 i figurerna 1-6 och befinner sig i dessa 4 80622 figurer i beredskapsläge för att kapa mineralullsbanan 1.The cutting device is generally designated by reference numeral 2 in Figures 1-6 and in these 4,80622 figures is in readiness mode for cutting the mineral wool web 1.

Kapningsanordningen 2 uppvisar en vagn 3, pd vilken de egentliga, eller aktiva, kapningsdonen är monterade. Vagnen 3 är monterad pd ett underrede 4, som uppvisar i 5 mineralullsbanans 1 riktning löpande skenor eller gejder 5, längs vilka vagnen 3 kan röra sig pd hjul, kulbuss-ningar eller liknande.The cutting device 2 has a trolley 3, on which the actual, or active, cutters are mounted. The carriage 3 is mounted on a base 4, which has rails or guides 5 running in the direction of the mineral wool web 1, along which the carriage 3 can move on wheels, ball bushings or the like.

De aktiva kapningsdonen uppvisar ett tunnt skärblad 6, vars skäregg antingen kan vara en enhetlig knivegg, 10 eller, sdsom är visat i figur 7, kan vara knivtandad sd, att de enskilda knivtändernas eller -eggarnas 7 utstdende hörn 8 är riktade bakdt i relation till skärbladets 6 rö-relsekomponent pd tvären över mineralullsbanan 1. De i figur 7 visade enskilda kniveggarna 7 utgöres lämpligen av 15 pd skärbladet 6 infästade, knivslipade hdrdmetallskär. Med dylika hdrdmetallskär blir skärbladets tjocklek vanligen omkring 2,5-3 mm. Om man avstdr frdn dylika hdrdmetallskär kan man göra skärbladet 6 betydligt tunnare, ända ned tili 0,5 mm, men skäreggen mdste dd omslipas oftare.The active cutters have a thin cutting blade 6, the cutting edge of which can either be a uniform knife edge, or, as shown in Figure 7, can be knife-toothed, such that the protruding corners 8 of the individual knife teeth or eggs 7 are directed backwards in relation to The movement component of the cutting blade 6 pd across the mineral wool web 1. The individual knife walls 7 shown in Figure 7 are suitably constituted by the 15 p cutter blade 6, knife-sharpened cemented carbide inserts. With such cemented carbide inserts, the thickness of the cutting blade is usually about 2.5-3 mm. If you cut away from such cemented carbide inserts, you can make the cutting blade 6 considerably thinner, down to 0.5 mm, but the cutting edge must die more frequently.

20 Skärbladet 6 är sträckt i en ram 9, varigenom man säkerställer att skäreggen hdlles rak under kapningen. För att fd ett jämnt ullsnitt utan "fransar" är det lämp-ligt att anordna en borstvals 10 som mothdll mot skärbladet 6 nedanom mineralullsbanan 1, sd att skärbladet kan 25 tränga in, ca. 10 mm, i borsten pä valsen. Valsen behöver inte vara driven ty mineralullsbanan driver valsen sd att inte tvd kapningar efter varandra sker pd samma ställe av borsten.The cutting blade 6 is stretched in a frame 9, thereby ensuring that the cutting edge is kept straight during cutting. In order to obtain a uniform wool cut without "fringes", it is convenient to arrange a brush roll 10 which mothdll against the cutting blade 6 below the mineral wool web 1, so that the cutting blade can penetrate, approx. 10 mm, in the brush on the roller. The roller need not be driven because the mineral wool web drives the roller so that no two cuts in succession occur at the same place of the brush.

I utförandet enligt figurerna 1-3 är ramen 9 med 30 inspänt skärblad 6 monterat pä vagnen 3 via hjul 11, som löper längs snedställda skenor 12, eller tili exempel me-delst motsvarande kulbussningar, och kapningsrörelsen är anordnad att utföras medelst en motor 13, till exempel en kuggväxelmotor, som är ansluten tili ramen 9 via en vev-35 stake 14. Dä motorn 13 roterar motsols frdn det i figur 1 5 80622 visade läget, drar vevstaken 14 ramen 9 längs skenorna 12 snett nedät och skärbladet 6 kapar mineralullsbanan 1. En speciell fördel med ett dylikt utförande är att man kan uppnä en under kapningsrörelsen kraftigt tilltagande skär-5 kraft, varigenom detta utförande är särskilt väl ägnat för att kapa mineralullsbanor med hög densitet. För varje snitt gör vevstaken en fram- och ätergäende rörelse, sä att kuggväxelns sekundäraxel där vevstakens drivarm är fästad gör ett varv per snitt. Utförandet har även den 10 fördelen att ha en mjuk start- och stopperiod om ca. 50-100 millisekunder vid en skärtid om ca. 1 sekund, varvid växelns utgäende axel alltsä roterar 60 varv per minut.In the embodiment according to Figures 1-3, the frame 9 with clamped cutting blade 6 is mounted on the trolley 3 via wheels 11 running along inclined rails 12, or for example with corresponding ball bushes, and the cutting movement is arranged to be carried out by means of a motor 13, for example, a gear motor connected to the frame 9 via a crank rod 14. As the motor 13 rotates counterclockwise from the position shown in FIG. 1, the crank 14 pulls the frame 9 along the rails 12 obliquely downward and the cutting blade 6 cuts the mineral wool web 1. A particular advantage of such an embodiment is that it is possible to achieve a sharp cutting force during the cutting movement, whereby this embodiment is particularly well suited for cutting high density mineral wool webs. For each cut, the crank makes a reciprocating movement, such that the secondary shaft of the gearbox where the crank's drive arm is attached makes one turn per cut. The design also has the advantage of having a soft start and stop period of approx. 50-100 milliseconds at a cutting time of approx. 1 second, whereby the output shaft of the gear rotates 60 revolutions per minute.

I det i figurerna 4-6 visade alternative utförandet utföres kapningsrörelsen med hjälp av 4 företrädesvis 15 pneumatiska skyttelcylindrar 15. Skyttelcylindrarna 15, liksom de i figurerna 1 och 2 visade styrningarna 11 och 12, är lämpligen placerade parvis pä vardera sidan av ramen 9 vid skärbladets infästningsändar. Säväl skyttelcylindrarna 15 som styrningarna 11 och 12 är lämpligen mon-20 terade pä snedstellda stöd 18 i fast förbindelse med vag-nen 3. Ramen 9 är förbunden med de pä vardera sidan om denna liggande skyttelcylindrarna 15 respektive hjulen 11 medelst tvärgäende stöd 19.In the alternative embodiment shown in Figures 4-6, the cutting movement is carried out by means of 4 preferably 15 pneumatic shuttle cylinders 15. The shuttle cylinders 15, as well as the guides 11 and 12 shown in Figures 1 and 2, are suitably placed in pairs on each side of the frame 9 at the cutting blade. root ends. The shuttle cylinders 15 as well as the guides 11 and 12 are suitably mounted on inclined supports 18 in fixed connection with the carriage 3. The frame 9 is connected to the respective sides of this shuttle cylinders 15 and the wheels 11 by means of transverse support 19.

Vagnen 3 är anordnad att röra sig pä skenorna 5 25 främät synkront med mineralullsbanans hastighet under skärförloppet, som inklusive retur av skärbladet 6 tili startpositionen tar omkring en sekund, varefter vagnen 3 ätergär till sin pä ritningen visade utgängsposition pä ytterligare ungefär en sekund. Anordningen är nu klar för 30 en ny kapning. Sälunda uppnär man en kapningsfrekvens av omkring 30 snitt per minut.The trolley 3 is arranged to move on the rails 5 in front synchronously with the velocity of the mineral wool web during the cutting process, which including return of the cutting blade 6 to the starting position takes about one second, after which the trolley 3 returns to its drawing in the starting position for a further approximately one second. The device is now ready for a new cut. Thus, a cutting frequency of about 30 cuts per minute is achieved.

Synkroniseringen av vagnens 3 hastighet tili mineralullsbanans hastighet kan anordnas pä olika sätt.The synchronization of the speed of the carriage 3 to the speed of the mineral wool web can be arranged in various ways.

I utförandet enligt figurerna 1-3 är vagnen 3 dri-35 ven av en servomotor 20, som via en mellanaxel 21 driver 6 80622 tvä kuggremmar 22. Kuggväxelmotorn 13, som är mor;terad pa vagnen 3, kan vara en standard trefasasynkronbromsmotor med fast varvtal, medan servomotorn 20 drives av en synk-roniseringsenhet som hela tiden ser tili att vagnen 3 rör 5 sig med exakt samma hastighet som produktionslinjen under den tid skärningen pägär.In the embodiment according to Figures 1-3, the carriage 3 is driven by a servomotor 20, which drives 6 80622 two gear belts via an intermediate shaft 21. The gearbox motor 13 mounted on the carriage 3 can be a standard three-phase synchronous brake motor with fixed speed, while the servomotor 20 is driven by a synchronization unit which constantly sees to it that the carriage 3 moves at exactly the same speed as the production line during the cutting time.

Alternativt kan man, säsom är antytt tydligast i figur 5, ersätta kuggremmarna 22 med mutterskruvar 23, vilka kan drivas av tvä servomotorer 24, som är synkroni-10 serade sinsemellan.Alternatively, as indicated most clearly in Figure 5, the gear belts 22 can be replaced with nut screws 23, which can be driven by two servomotors 24, which are synchronized with each other.
