Anordning i en produktionslinje för mineralull Föreliggande uppfinning avser en anordning i en produktionslinje för mineralull, i vilken produktionslinje 5 till fiber omvandlad mineralsmälta samlas till en tunn primärullbana pä en transportör, som för tili en pendel-transportör, som lägger ut primärullbanan pä en mottag-ningstransportör tili en av ett flertal skikt bestäende sekundärullbana.BACKGROUND OF THE INVENTION The present invention relates to a device in a mineral wool production line in which production line 5 of fiber-transformed mineral melt is assembled into a thin primary roller web on a conveyor, which for a pendulum conveyor which places the primary roller web on a receiving line. transport conveyor to a secondary layer consisting of a plurality of layers.

10 Vid mineralullstillverkning omvandlas en mineral smälta till fiber med en spinnmaskin som är försedd med en avbläsning som bläser de bildade fibrerna in i en fiber-uppsamlingskammare samtidigt som ofibrerade stelnade smä smältpartiklar kallade pärlor separeras frän fibern. Den 15 bildade fibern samlas pä en transportör tili en tunn fi-bermatta kallad primärullbana som transporteras vidare tili en pendeltransportör som lägger ut den pä en läng-samgäende mottagningstransportör. Härvid bildas en av män-ga skikt bestäende sekundärullbana.In mineral wool manufacturing, a mineral melt is converted to fiber by a spinning machine provided with a blow-off which blows the formed fibers into a fiber collection chamber while separating non-vibrated solidified melt melt particles called beads from the fiber. The formed fiber is collected on a conveyor into a thin fiber mat called a primary roller conveyor which is further conveyed to a pendulum conveyor which places it on a longitudinal receiving conveyor. Hereby a secondary layer consisting of many layers is formed.

20 Genom pendelutläggningen strävar man till att mins- ka volymviktsvariationerna hos sekundärullbanan sä att man fär en jämn ullfördelning tvärs över hela produktionslin-jens bredd.20 The pendulum layout aims to reduce the volume weight variations of the secondary wool web so that a uniform wool distribution is obtained across the entire width of the production line.

Primärullbanan som har en ytvikt om 200-400 g/m2 25 pendlas ut tili en sekundärullbana i vanligen minst sex skikt pä en mottagningstransportör som rör sig i 90° vin-kel mot den ankommande ullbanan och gär med synkron has-tighet med den efterföljande Iinjen.The primary roller web having a basis weight of 200-400 g / m2 is commuted out to a secondary roller web, usually at least six layers, on a receiving conveyor moving at 90 ° angle to the arriving wool web and preferably with synchronous speed with the subsequent line. .

Volymvikten eller ytvikten vid en given produkt-30 tjocklek är en av de viktigaste kvalitetsparametrar som skall hällas inom vissa givna gränser vid tillverkningen.The volume weight or surface weight at a given product thickness is one of the most important quality parameters to be poured within certain given limits during manufacture.

Pä grund av variationerna i smältflödet tili spinn-maskinen varierar fiberproduktionen per tidsenhet och sä-ledes även ytvikten hos primärbanan.Due to the variations in the melt flow to the spinning machine, the fiber production varies per unit of time and thus also the surface weight of the primary web.

:T: 35 2 90049: T: 35 2 90049

Man styr hastigheten hos mottagningstransportören för att kompensera dessa variationer hos primärbanan, var-vid man har använt olika mätsignaler, säsom spinnmaskinens effektförbrukning, undertrycket i ulluppsamlingskammaren 5 mm för att fä en tidig indikation om förändringar i den momentana fiberproduktionsmängden per tidsenhet. Dessa hjälpsignaler är inte absolute och ett stabilt samband mellan dessa signaler och fiberproduktionen existerar inte.The speed of the receiving conveyor is controlled to compensate for these variations of the primary path, whereby various measuring signals, such as the power consumption of the spinning machine, have been used, suppressed in the wool collection chamber 5 mm to give an early indication of changes in the instantaneous fiber production amount per unit time. These auxiliary signals are not absolute and a stable relationship between these signals and fiber production does not exist.

10 Man har försökt väga primärullbanan, men pga den läga ytvikten och höga hastigheten hos primärbanan kommer man inte till en större vägningsnoggrannhet än ±5 %, var-för man inte kan styra hastigheten hos mottagningstransportören sä att man när nämnvärt bättre noggrannhet hos 15 den utpendlade ullbanans ytvikt än hos vägningen av primärullbanan.Attempts have been made to weigh the primary runway, but due to the low surface weight and high speed of the primary runway, no greater weighing accuracy is reached than ± 5%, whereas it is not possible to control the speed of the receiving conveyor so that substantially better accuracy of the dispatched wool web surface weight than the weight of the primary wool web.

Ett annat känt förfarande är att väga ullbanan pä en vägtransportör efter mottagningstransportören och reg-lera hastigheten hos denna med hjälp av tidigare nämnda 20 hjälpsignaler, som korrigeras med hjälp av ytviktssignalen frän den utpendlade ulien.Another known method is to weigh the wool web on a road conveyor after the receiving conveyor and control its speed by means of the aforementioned auxiliary signals, which are corrected by means of the surface weight signal from the pendulum wool.

En efterföljande vägning av den utlagda ullbanan fär en rätt läng tidsfördröjning tills den kan ge korrek-tionssignal tili en ytviktsregulator, varvid flera meter 25 utlagd ullbana kan ha felaktig ytvikt. Normalt räknas med att man med ovannämnda regleringsförfaranden kan fä en ytviktsnoggrannhet om ±3-4 %.A subsequent weighing of the laid wool web will have a fairly long time delay until it can give a correction signal to a surface weight regulator, where several meters of laid wool web may have incorrect surface weight. Normally, it is expected that with the above mentioned control procedures a surface weight accuracy of ± 3-4% can be obtained.

Vid start och stopp i fiberproduktionen eller primärullbanan fordras dessutom ett sofistikerat datorprogram 30 för att beräkna när primärullbanan läggs ut pä mottagningstransportören sä att denna kan starta och stoppa i rätt ögonblick för att undvika en för stor ullsamling eller tomkörning av mottagningstransportören.In addition, at the start and stop of the fiber production or primary roller web, a sophisticated computer program 30 is required to calculate when the primary roller web is laid out on the receiving conveyor so that it can start and stop at the right moment to avoid an excessive wool collection or empty run of the receiving conveyor.

Ändamälet med uppfinningen är att ästadkomma en ny 35 anordning, med vars hjälp ovannämnda olägenheter kan und- 3 90049 vikas och en större noggranhet uppnäs hos den utpendlade sekundärullbanans ytvikt.The object of the invention is to provide a new device, by means of which the aforementioned disadvantages can be avoided and a greater accuracy is achieved in the surface weight of the suspended secondary roller web.

Anordningen enligt uppfinningen är i huvudsak kän-netecknad av att mottagningstransportören omfattar en vä-5 sentligen under pendeltransportören liggande del försedd med don för att väga ytvikten av den pä nämnda del bilda-de sekundärullbanan, och att vägningsdonen via en regulator är kopplade till en drivmotor hos nämnda del för att styra dennas hastighet 10 sä, att man trots variationer i primärullbanans ytvikt erhäller en sekundärullbana med noggrant konstant ytvikt.The device according to the invention is characterized in that the receiving conveyor comprises a portion lying substantially below the pendulum conveyor with means for weighing the surface weight of the said secondary roller web formed on said part and that the weighing means are connected to a drive motor via a regulator. of said portion to control its velocity 10, so that, despite variations in the primary weight of the primary roller web, a secondary roller web of precisely constant surface weight is obtained.

Hastigheten hos den i enlighet med uppfinningen vägande delen av mottagningstransportören kan regleras sä att ytvikten hos den utpendlade ullbanan hela tiden hälls 15 konstant pä en inställd nivä med en noggrannhet som är bättre än ±1 %.The speed of the portion of the receiving conveyor weighing in accordance with the invention can be controlled so that the surface weight of the commuted wool web is constantly poured at a set level with an accuracy better than ± 1%.

Enligt en föredragen utföringsform av uppfinningen är den vägande delen av mottagningstransportören, eller den sk vägningstransportören, mekaniskt balanserat upp-20 hängd under pendeltransportören sä att upphängningspunkten blir pä bakre sidan av pendeltransportörens mittlinje. Främre delen eller den delen av vägningstransportören där den utpendlade ullbanan mätäs vidare tili efterföljande transportörer som för den vidare tili härdugnen är upp-25 hängd pä viktavkännande lastgivare som sälunda endast kom-mer att känna av den utpendlade ullbanans vikt och vara oberoende av egenvikten hos vägningstransportören.According to a preferred embodiment of the invention, the weighing portion of the receiving conveyor, or the so-called weighing conveyor, is mechanically balanced suspended below the pendulum conveyor so that the suspension point is at the rear of the pivot conveyor centerline. The front part or part of the weighing conveyor where the shuttled wool web is further measured to subsequent conveyors which for the further to the hearth is hung on weight-sensing load transducers which will only sense the weight of the shuttled wool web and be independent of the weight of the weighing conveyor. .

Med den föreslagna konstruktionen är egenvikten hos hela vägningstransportören ca 400 kg och ullbanans vikt 30 maximalt ca 30 kg, och minimalt ca 4 kg.With the proposed construction, the intrinsic weight of the entire weighing conveyor is about 400 kg and the weight of the wool web is at most about 30 kg, and at least about 4 kg.

Lastgivarna har en maximinoggrannhet om 0,1 % och kan i ovan beskrivna fall väljas för ett mätomräde om 0-40 kg, varvid mätnoggrannheten även vid den lättaste ullbanan blir ±1 % i stället för ±10 % om hela vägnings-35 transportören skulle bäras upp av lastgivare.The load transducers have a maximum accuracy of 0.1% and in the case described above can be selected for a measurement range of 0-40 kg, with the measurement accuracy even at the lightest wool web being ± 1% instead of ± 10% if the entire weighing conveyor was to be carried. up by the load transducer.

Genom att reglera hastigheten hos vägningstrans-portören sä att vikten hälls konstant pä denna, mätäs det hela tiden bort en utlagd ullbana med konstant ytvikt sä att hastigheten motsvarar den ullmängd som frän pendeln 5 mätäs ned pä vägningstransportören, oberoende av variatio-ner i ytvikten hos den primärbana som kommer frän pendel-transportören.By adjusting the speed of the weighing conveyor so that the weight is kept constant on it, a laid-out wool web with constant surface weight is constantly measured so that the speed corresponds to the amount of wool measured from the pendulum 5 on the weighing conveyor, regardless of variations in the weight of the the primary path coming from the shuttle carrier.

Vid den lägsta ytvikten ca 2 kg/m2 hos den utpendla-de ullbanan som ger en vikt om ca 4 kg pä lastgivarna rör 10 sig vägningstransportören och de efterföljande transportö-rerna med en maximal hastighet om ca 20 m/min eller 0,33 m/s. En 10 % ändring i ytvikten, som är ca 300 g/m2 hos primärbanan känns efter 1 sekund av lastgivarna som ett ca 1,5 % stort fel och efter 3 sekunder som ett ca 5 % stort 15 fel för att efter 6 sekunder siä ut som ett fullt 10 % stort fel i den utpendlade ullens ytvikt om vägningstransportören har konstant hastighet.At the lowest surface weight of about 2 kg / m2 of the suspended wool web which gives a weight of about 4 kg on the load transducers, the weighing conveyor and the subsequent conveyors move at a maximum speed of about 20 m / min or 0.33 m / s. A 10% change in the surface weight, which is about 300 g / m2 of the primary web, is felt after 1 second by the load sensors as a 1.5% large error and after 3 seconds as a about 5% large error, after 6 seconds as a full 10% error in the weight of the shuttled wool if the weighing conveyor has a constant speed.

Genom att omedelbart när mätgivarna känner av ett fel i ytvikten läta en regulator styra hastigheten hos 20 vägningstransportören för att eliminera felet i vikten hos den utlagda ullbanan, kan man med en enkel PID-regulator styra hastigheten sä att variationerna i ytvikten hälls inom ±1 %, inom en längd av 0,5 m av den utpendlade ullbanan, vilket inte kan uppnäs med tidigare kända och be-25 skrivna förfaranden.As soon as the sensors detect an error in the surface weight, let a regulator control the speed of the weighing conveyor to eliminate the error in the weight of the laid wool web, one can control the speed with a simple PID controller so that the variations in the surface weight are kept within ± 1% , within a length of 0.5 m of the shuttled wool web, which cannot be achieved by previously known and described methods.

Om primärullbanan upphör, kommer lastgivarna i ovannämnda fall att inom en sekund känna av att den utpendlade ullbanan har blivit 15 % för lätt och kan ge signal att stanna vägningstransportören sä att ingen större 30 störning i den utpendlade ullbanans ytvikt uppstär. När det äter börjar pendlas ut en primärullbana kan vägningstransportören snabbt köras upp i rätt hastighet när lastgivarna känner av att vikten motsvarar den inställda ytvikten.If the primary wool web ceases, the loaders in the above-mentioned cases will sense within one second that the shuttled wool web has become too light and can give a signal to stop the weighing conveyor so that no major disturbance in the shed wool web's surface weight increases. When eating begins to commute out of a primary roller track, the weighing conveyor can quickly be driven up at the correct speed when the load sensors sense that the weight corresponds to the set surface weight.

35 5 90049 Förfarandet att väga ullbanan direkt under pendeltransportören pä vägningstransportören medger att kompen-sera för en ändring av volymvikten hos primärullbanan under tiden sekundärullbanan bildas, varvid volymviktsva-5 riationerna hos denna kan hällas inora mycket snäva tole-ranser.The method of weighing the wool web directly below the pendulum conveyor on the weighing conveyor allows to compensate for a change in the volume weight of the primary wool web during the time the secondary wool web is formed, the volume weight variations thereof being poured into very narrow tolerances.

I det följande skall närmare beskrivas ett pä bifo-gade ritning schematiskt visat föredraget utföringsexem-pel.In the following, a schematic diagram of the preferred embodiment is shown in the accompanying drawing.

10 Ritningen visar, sett frän sidan, den nedre änden av produktionslinjens pendeltransportör samt den därpä f öl j ande mottagningstransportören.10 The drawing shows, from the side, the lower end of the production line's pendulum conveyor and the subsequent receiving conveyor.

Pä ritningen är pendeltransportören betecknad med 2. Mottagningstransportören omfattar en väsentligen under 15 pendeltransportören 2 liggande vägningstransportör 1, ett rullbatteri 7 samt en efterföljande linjetransportör 8. Pendelrörelsens mittlinje är betecknad med 2a och rörel-sens ändlinjer, dvs primärbanans kanter med 2b. Vägningstransportören är upphängd i en korsfjäder 3, bakom pendel-20 rörelsens mittlinje 2a, pä vardera sidan av transportören sä att den mekaniskt är nästan helt utbalanserad. Vid torn transportör skall lastgivare 4, företrädesvis även de en pä vardera sidan, placerade mellan korsfjädern 3 och transportörens utgängsände, endast känna av en taralast om 25 ca 20 % av lastgivarnas mätomräde, vilken i vägningselek-troniken tareras bort. Vägningselektroniken ger en styr-signal tili en regulator som inte finns p& ritningen men vilken styr hastigheten pä en motor 5, vilken driver vägningstransportören 1 sä att vikten av den utlagda ullbanan 30 som lastgivarna 4 känner av pä sträckan mellan korsfjädern 3 och transportörens ändrulle vid övergängen tili det efterföljande rullbatteriet 7 hela tiden hälls konstant. Företrädesvis är lastgivarna 4 placerade ätminstone väsentligen vid det ställe, där sekundärullbanan 6 uppnätt slut-35 lig tjocklek, lämpligen säledes vid slutet av vägnings- 6 90049 transportören 1, före rullbatteriet 7. Det är dock även möjligt att utföra vägningen tidigare. Den efterföljande linjetransportören 8 och rullbatteriet 7 drivs av en sepa-rat motor synkront med motorn 5 som driver vägnigstrans-5 portören 1. Motorn 5 är fästad pä ramen för vägningstrans-portören 1. Den ram 9, pä vilken korsfjäder- och lastgiva-relementen är fästade, hälls pä konstant höjd av ett stöd 10 i den ände, som ligger närmare pendeltransportören, medan en anordning 11, t ex en hydraulisk cylinder, kan 10 höja eller sänka den andra änden av ramen 9 som även bär upp rullbatteriet 7 samt ena änden av den efterföljande linjetransportören 8. Ritningen visar vägningstransportö-ren i sitt lägsta inställningsläge, dvs för den längsam-maste hastigheten och högsta ytvikten hos den utpendlade 15 ullbanan 6. Lutningen pä ramen 9 stalls in med hjälp av anordningen 11 sä den utpendlade ullbanans 6 Övre yta ligger parallellt med pendeltransportörens 2 undre kant 12. Den utpendlade ullbanan 6 kommer i det lägsta inställda läget som visas i figur 1 att vara ca 80 cm tjock och 20 i det högsta inställda läget ca 15 cm vid, vilken inställ-ning vägningstransportören 1 rör sig med sin högsta has-tighet.In the drawing, the pendulum conveyor is indicated by 2. The receiving conveyor comprises a weighing conveyor 1 lying substantially below the pendulum conveyor 2, a rolling coil 7 and a subsequent line conveyor 8. The center line of the pendulum movement is indicated by 2a and the end lines of the pivotal conveyor. The weighing conveyor is suspended in a cross spring 3, behind the center line 2a of the pendulum movement, on each side of the conveyor so that it is mechanically almost completely balanced. In the case of tower conveyors, the load transducer 4, preferably also one on each side, located between the cross spring 3 and the output end of the conveyor, should only sense a total load of about 20% of the measuring range of the load transducers, which in the weighing electronics is removed. The weighing electronics provide a control signal to a controller which is not in the drawing but which controls the speed of a motor 5, which drives the weighing conveyor 1 such that the weight of the laid wool web 30 as the load sensors 4 senses on the distance between the cross spring 3 and the conveyor end roller at the transition. to the subsequent rolling coil 7 is constantly poured. Preferably, the load transducers 4 are positioned at least substantially at the point where the secondary roll web 6 has reached final thickness, preferably at the end of the weighing conveyor 1, before the rolling coil 7, however, it is also possible to carry out the weighing earlier. The subsequent line conveyor 8 and roller coil 7 are driven by a separate motor synchronously with the motor 5 driving the weighing conveyor 1. The motor 5 is attached to the frame of the weighing conveyor 1. The frame 9, on which the cross-spring and load-bearing elements are attached, are held at a constant height by a support 10 at the end which is closer to the pendulum conveyor, while a device 11, such as a hydraulic cylinder, can raise or lower the other end of the frame 9 which also supports the roller battery 7 and one The drawing shows the weighing conveyor in its lowest setting position, that is, for the slowest speed and highest surface weight of the pivoted wool web 6. The inclination of the frame 9 is set by means of the device 11, so the pendular wool web 6 The upper surface is parallel to the lower edge 12. of the pendulum conveyor 2. The suspended wool web 6 comes in the lowest set position shown in from 1 being about 80 cm thick and 20 in the highest set position about 15 cm at which setting the weighing conveyor 1 moves at its highest speed.
