A presence sensor combined to a first storage carrier for detecting a presence of a second storage carrier. A load cell measures the weight of the material expelled from the first storage carrier. A scale controller in communication with the presence sensor responds to the presence of the second storage carrier by recording of the weight measurement from the load cell.

An apparatus or method for weighing and/or measuring the flow rate of quantity of a particulate flowing out of a hopper wherein the hopper is isolated from the other components of the apparatus. The apparatus and method are adapted to generate a decoupling point boundary that demarcates the total amount of particulate in the hopper into portions that are not fully supported and portions that are fully supported by the hopper. The particulate is in continuous contact with itself from the inlet to the outlet, with the particulate contained between the isolated hopper and the rest of the components of the system by a flexible coupling or some other method of containment. The invention has the advantages of higher accuracy, decreased cost and complexity, and greater reliability than other solid particulate weighing systems of the prior art, particularly when dealing with low density particulates.

A material handling machine dispenses uniformly metered charges of smoking material from a bulk supply, by means of a metered material feeder that has a first hopper with an opening disposed over a first horizontal chute. The first chute is mounted on slanted springs and has a dispensing end above a second chute also mounted upon slanted springs. The second chute discharges onto a tippable weighing tray above a set of nested hoppers in which one is fixed and the other is vertically movable. A weight sensor may be attached to the tippable tray or the fixed hopper, or both. The move-able hopper may comprise a forming belt indenter to form a trough in a cigarette rolling apparatus. The first hopper may include an agitator that has at least one vertical rod for stirring the bulk material. The dispensing end of the first chute may also include a rotating rake.

A machine vision camera combined to one of the first storage carrier and the second storage carrier for detecting an offloading event. A sensor for measuring the weight of the material offloaded from the first storage carrier to the second storage carrier. A scale controller in communication with the machine vision camera and the sensor. The scale controller enters a tear mode in response to the beginning of offloading event and records and stores the weight of material offloaded from the first storage carrier to the second storage carrier as measured by the sensor.

The method according to the invention provides a way to continue gravimetric weighing of bulk material during refilling of a gravimetric metered dispensing unit, and to determine the mass of the refilled bulk material using a refilling container during the filling operation material and so determine the actual mass flow discharged during refilling in real time or on average in order to adjust it to a target mass flow.
