WEIGHING SYSTEM IN A MAGLEV CONVEYING SYSTEM

A magnetic levitation conveying system conveys products on trays and measures the weight of the product without requiring removal of the product or tray. A track below the trays has magnetic levitation coils that generate a magnetic field when energized. The trays include magnets or other levitation elements that interact with the magnetic levitation coils to generate a propulsive levitating forceon the tray. A sensor measures a parameter in the system to correlate the parameter with the weight of the conveyed product. The parameter can be a floating height of the tray above the track, an amount of energy necessary to maintain a particular floating height of the tray above the track, a force resulting from accelerating or decelerating the tray, a force required to maintain a desired curveradius when the tray moves around a curve, a force that counteracts an acceleration caused by an incline or other suitable indicator of weight. 一种磁悬浮输送系统，其在托盘上输送产品并在不需要移除产品或托盘的情况下测量产品的重量。位于托盘下方的轨道具有磁悬浮线圈，所述磁悬浮线圈在通电时产生磁场。托盘包括磁
