Abstract

Apparat for automatisk veiing av et masseprodukt av partikkelformet materiale, såsom korn. Det omfatter en veieboholder med automatisk tilførsel og bortførsel av materiale, veieutstyr for beholderen, som omfatter et antall elektromekaniske lastceller og et antall opphengningspunkter for å gå elektrisk signal proporsjonalt med krafta som uteves på hver lastcelle. Signalet brukes for å styre tilførsel og bortførsel av masse. Det finnes midler for å kontrollere nøyaktigheten på de målte verdiene, som omfatter lastceller (17) for endelig bestemmelse av totalvekten på veiebeholderen. Spesielt er at det finnes for kontrollveiing sekundære elektromagnetiske lastceller (19), hvis utgangssignal sammenlignes med en komparator (30) med signalet fra de primære lastcellene (17). Det resulterende signalet brukes for å styre (32) tilførselg bortførsel. Fortrinnsvis er ei rekke lastceller (17,19) mekanisk og seriemessig innstallert på et opphengningssted på en slik måte at den sekundære detektor (19) til en enhet (1) utsettes for samme vektbelastning (P) som den tilsvarende primærdetektor (17) og kontrollerer signalet fra denne. Veieenhetene (1) omfatter fordelaktig ei U-formet ramme (15) hvor den primære lastcella (17) er festet til det øvre beinet (16) og den sekundære lastcella (19) til det nedre beinet (18), mens de to beina er forbundet med ei vertikal forbindelsesstang (20).Apparatus for automatically weighing a pulp product of particulate matter, such as grain. It comprises a weighing container with automatic supply and removal of material, weighing equipment for the container, which comprises a number of electromechanical load cells and a number of suspension points for passing electrical signal in proportion to the force exerted on each load cell. The signal is used to control the supply and removal of pulp. There are means for checking the accuracy of the measured values, which include load cells (17) for the final determination of the total weight of the weighing container. In particular, there are secondary electromagnetic load cells (19) for control weighing, the output signal of which is compared with a comparator (30) with the signal from the primary load cells (17). The resulting signal is used to control (32) supply drain. Preferably, a series of load cells (17, 19) are mechanically and serially installed at a suspension location in such a way that the secondary detector (19) of a unit (1) is subjected to the same weight load (P) as the corresponding primary detector (17) and controls the signal from this. The weighing units (1) advantageously comprise a U-shaped frame (15) where the primary load cell (17) is attached to the upper leg (16) and the secondary load cell (19) to the lower leg (18), while the two legs are connected to a vertical connecting rod (20).
