Vid transportbandets pàmatnings- ände är anordnad en trattformad mottagningsbehállare 13 med mynningen strax ovanför transportbandet, och denna mottagningsbehällare tillföres material fràn en kontinuerligt löpande transportör 14. Vid trans- portbandets utmatningsände är anordnad en avskrapare 15 för rengöring av transportbandet. Mottagningsbe- hàllarens mynning är försedd med ett spjäll 16 eller liknande organ för temporär avstängning av material- tillförseln till transportbandet. Spjället är för- bundet med ett manöverdon 17, som är funktionellt förbundet med en styr- och beräkningsenhet (dator) 18, vilken också är funktionellt förbunden med last- cellerna. Styr- och beräkningsenheten samordnar av- stängning av materialtillförseln medelst spjället och inkopplingen av mätsignalerna fràn lastcellerna, sà att mätsignalerna bearbetas endast dä material- tillförseln är avstängd, för beräkning av vikten av material pà transportbandet i beroende av signalerna fràn lastcellerna. Till styr- och beräkningsenheten är ansluten en display 19 för indikering av mätre- sultatet och/eller en apparat för registrering av mätresultatet. 463 050 2 10 15 20 25 30 35 eg rubber cloth, textile cloth, steel mesh or adjusting plates and is supported by a weighing device comprising four load cells 12. At the feed end of the conveyor belt a funnel-shaped receiving container 13 is arranged with the mouth just above the conveyor belt, from a continuously running conveyor 14. At the discharge end of the conveyor belt, a scraper 15 is arranged for cleaning the conveyor belt. The mouth of the receiving container is provided with a damper 16 or similar means for temporarily shutting off the material supply to the conveyor belt. The damper is connected to an actuator 17, which is functionally connected to a control and calculation unit (computer) 18, which is also functionally connected to the load cells. The control and calculation unit coordinates switching off the material supply by means of the damper and the connection of the measurement signals from the load cells, so that the measurement signals are processed only when the material supply is switched off, for calculating the weight of material on the conveyor belt depending on the signals from the load cells. Connected to the control and calculation unit is a display 19 for indicating the measurement result and / or an apparatus for recording the measurement result.

Fig. 1 visar den första fasen av funktionscy- keln, fyllningsfasen, varunder kontinuerligt ankom- mande material via mottagningsbehàllaren 13 tillfö- res transportbandet 11 och vidarebefordras pà detta.Fig. 1 shows the first phase of the operating cycle, the filling phase, during which continuously arriving material via the receiving container 13 is fed to the conveyor belt 11 and forwarded thereon.

Fig. 2 visar hur materialtillförseln till transportbandet 11 temporärt avbrytes, innan det tillförda materialet när transportbandets utmat- ningsände. Aktiveringen av manöverdonet 17 för stängning av spjället 16 sker pà signal frän styr- och beräkningsenheten 18 och samordnas med inkopp- 10 15 20 25 30 35 3 465 050 lingen av mätsignalerna från lastcellerna 12.Fig. 2 shows how the material supply to the conveyor belt 11 is temporarily interrupted, before the supplied material reaches the discharge end of the conveyor belt. The actuation 17 of the actuator 17 for closing the damper 16 takes place on a signal from the control and calculation unit 18 and is coordinated with the connection of the measurement signals from the load cells 12.

Fig. 3 visar själva vägningsfasen, då det kon- tinuerligt ankommande materialet temporärt uppsamlas i mottagningsbehållaren 13, medan transportbandet 11 och därpå befintligt material väges. Materialets vikt beräknas, indikeras på displayen 19 och/eller registreras på en skrivare, ett räkneverk eller en dylik anordning. Urkopplingen av mätsignalerna från lastcellerna 12, innan materialet när transportban- dets utmatningsände, samordnas av styr- och beräk- ningsenheten 18 med aktiveringen av manöverdonet 17 för öppning av spjället 16.Fig. 3 shows the weighing phase itself, when the continuously arriving material is temporarily collected in the receiving container 13, while the conveyor belt 11 and existing material are weighed. The weight of the material is calculated, indicated on the display 19 and / or registered on a printer, a counter or the like device. The disconnection of the measurement signals from the load cells 12, before the material reaches the discharge end of the conveyor belt, is coordinated by the control and calculation unit 18 with the activation of the actuator 17 for opening the damper 16.

Fig. 4 visar en avslutande tömningsfas och den samtidigt påbörjade fyllningsfasen i en ny funk- tionscykel. Under tömningsfasen matas det vägda ma- terialet ut över vändrullen 10 i utmatningsänden, samtidigt som materialtillförsel till transportban- det sker under successiv tömning av mottagningsbe- hållaren 13. Genom transportbandets kontinuerliga rörelse under det temporära avbrottet i material- tillförseln kommer det nu tillförda materialet och det redan vägda materialet att vara åtskilda av ett mellanrum 20 på transportbandet.Fig. 4 shows a final emptying phase and the filling phase started at the same time in a new function cycle. During the emptying phase, the weighted material is fed out over the reversing roller 10 at the discharge end, at the same time as material supply to the conveyor belt takes place during successive emptying of the receiving container 13. Through the continuous movement of the conveyor belt during the temporary interruption in the material supply, the already weighed material to be separated by a gap 20 on the conveyor belt.

Så snart allt det vägda materialet matats ut, aktiveras manöverdonet för stängning av spjället och inkopplas mätsignalerna från lastcellerna för be- stämning av det på transportbandet befintliga mate- rialets vikt, innan materialet nått transportbandets utmatningsände och ytterligare en ny cykel som den ovan beskrivna påbörjats.As soon as all the weighed material has been discharged, the actuator for closing the damper is activated and the measuring signals are connected from the load cells to determine the weight of the material on the conveyor belt, before the material reaches the discharge end of the conveyor belt and another new cycle is started.
