摘要： A yield measurement system for a cold planer having a conveyor is disclosed. The yield measurement system may include a hydraulic motor configured to propel the conveyor, a first sensor configured to generate a first signal indicative of a force acting on the conveyor by material being moved by the conveyor, and a second sensor configured to generate a second signal indicative of a pressure differential across the hydraulic motor. The yield measurement system may also include a controller in communication with the first and second sensors. The controller may be configured to determine when the conveyor is not transferring material based on the second signal, and automatically recalibrate the yield measurement system based on the first signal when the conveyor is not transferring material.

摘要： The continuous weighing meter [according to the invention has] having a conveyor belt [(1)] driven by a motor [(3)] and running over a guide roller (4), which is loaded with bulk material via an input funnel [(6)] from a feed arrangement [(9)]. In addition to a first weighing arrangement [(11)], which determines the gross loading of the loaded conveyor belt [(1)], the continuous weighing meter has a second weighing arrangement [(15)], which determines the tare loading of the empty, but possibly dirty and inhomogeneous conveyor belt [(1)]. The weighing distances have the lengths SB [(11)] or ST [(15)] and are separated by a distance L between homologous points. The weighing results are converted to digital form in evaluation [equipments (22, 21)] units and taken to a computer [(25)] which calculates the net loading of the conveyor belt [(1)]. Additionally the computer [(25)] monitors the running of the belt for slip using increment transmitters [(17, 23)] and associated counters [(18, 24)] and generally controls the feed arrangement [(9)].

摘要： A conveyor scale assembly for use in combination with a conveyor belt for weighing an article on the moving conveyor belt. The conveyor scale assembly is comprised of a slider bed which contacts the underside of the moving conveyor belt which generates a friction force between the conveyor belt and the slider bed. Attached to the slider bed is a sensor which continuously measures the friction force and transmits data representing the measured friction force. A CPU receives and processes the representative data and provides a weight for the article on the conveyor belt.

摘要： An apparatus for measuring the alignment of two or more adjacent targets while the targets are in motion is provided. The alignment measuring apparatus includes a plurality of alignment scanners, each adapted to detecting the arrival of an associated target. A speed scanner is spaced apart from the alignment scanner for detecting said first one of the targets. First timing means are provided for measuring a first time differential indicative of the time delay between detection of the leading and trailing targets by the alignment scanners to provide a measurement proportional to the misalignment between the targets. Second timing means measure a second time differential indicative of the time delay between detection of the first target by the speed scanner and its associated alignment scanner to provide a measurement that is proportional to the speed at which the lugs are traveling and determining whether adjacent lugs are within a selected alignment tolerance based in part upon the time differential measurements. An oscillatory timing clock operates at a selected frequency and the first timing means determines the number of clock pulses that occur during said first time differential measurement. Similarly, the second timing means determines the number of clock pulses that occur during the second time differential measurement. A frequency divider proportionally dividing the number of clock pulses in said second time differential measurement by a selectable number to provide an calibration output indicative of the maximum number of clock pulses that may occur within the first time differential measurement for the targets to be within a selected tolerance. The magnitude of the calibration output is then compared to the number of pulses within said first time differential measurement to determine whether the targets are within the selected tolerance.

摘要： The electrical rate output signal of an endless conveyor belt scale, consisting of the product of the load on the conveyor belt and the rate of travel of the conveyor belt, or the amplified weight of the load with the rate of travel of the conveyor belt constant, varies positively and negatively due to the tare weight variations of the conveyor belt and said tare weight variations are averaged out so that the algebraic sum of all the tare signal variations equal zero when the endless conveyor belt makes one complete revolution or multiple revolutions. The endless conveyor belt scale is also calibrated by a specified signal level having a magnitude equal to the signal level produced by either test chains or test weights on an endless conveyor belt weight sensing platform.
