Patent

CA 2704084

Material delivery systems, methods of delivering material and methods of calibrating such systems and methods are disclosed. The material delivery system includes a delivery vessel, a load cell, and automated weight calibration device. The delivery vessel has at least an outlet adapted for coupling to an unit. The load cell is configured to provide a metric indicative of an amount of material in the delivery vessel. The automated weight calibration device is configured to impart a known force onto the at least one load cell. A method includes delivering material to a unit and determining how much material is delivered by a change in weight of a delivery vessel, wherein the delivery vessel comprises a load cell; applying a known calibration force to the load cell; and comparing a metric from the load cell of the known calibration with an expected metric.

Cette invention concerne des systèmes de distribution de matériau, des procédés de distribution de matériau et des procédés de calibrage de ces systèmes et procédés. Le système de distribution de matériau comprend une cuve de distribution, une cellule de charge et un dispositif de calibrage pondéral automatisé. La cuve de distribution dispose d'au moins un orifice de sortie adapté pour être couplé à une unité. La cellule de charge est configurée pour donner une mesure indicative d'une quantité du matériau dans la cuve de distribution. Le dispositif de calibrage pondéral automatisé est configuré pour exercer une force connue sur la ou les cellules de charge. Un procédé comprend les étapes consistant à distribuer le matériau vers une unité et à déterminer la quantité du matériau distribuée grâce à une variation du poids d'une cuve de distribution, la cuve de distribution comprenant une cellule de charge ; à exercer une force de calibrage connue sur la cellule de charge ; et à comparer une mesure de la cellule de charge de calibrage connu avec une mesure attendue.
