摘要： There is provided an system and method for calibrating weigh assemblies of bulk material feeders using test chains of known weight and pitch. In particular, the present invention is a calibration checking system for a belt-type gravimetric feeder or conveyor having a weigh span section and comprises a continuous conveyor belt, at least one pair of support rollers and at least one weigh roller. A particular weigh roller is disposed under an upper strand of the conveyor belt and equidistant from each of the support rollers so that they are in planar alignment with one another. The calibration checking assembly also comprises a test chain having a chain pitch that is integrally divisible into the pitch of the weigh span section. In addition, portions of the conveyor belt on both sides of the weigh span are inclined equally at a single particular angle relative to the weigh span section. The calibration checking system further comprises a pair of load cells coupled to the ends of the weigh roller and a processor coupled to the loads cells for determining an optimal elevation for the weigh roller. The load cells and processor detect belt tension of the conveyor belt and analyze weigh load in relation to the belt tension.

摘要： A pivoted scale beam type of weighing device senses the weight of articles traveling on a continuously moving conveyor belt. The conveyor belt is periodically displaced upwardly from the weighing device during test intervals to check calibration by simultaneously removing the load of the conveyor from the weighing device while transferring a reference weight thereto. The weighing device is automatically adjusted during each test interval if there is a deviation from a proper reference reading.

摘要： A method for analyzing performance of a sorting system is provided. The method includes recording downtime experienced by the sorting system, recording runtime experienced by the sorting system, and recording an optimal characterization of a product stream to be sorted by the sorting system. The optimal characterization includes at least an optimal weight of a first commodity of the product stream. An actual characterization of the product stream as sorted by the sorting system is recorded. The actual characterization includes at least an actual weight of the first commodity sorted from the product stream. The method further includes determining the performance of the sorting system based on at least two of the downtime, the runtime, the optimal characterization, and the actual characterization.

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： The invention provides a method of assessing the weight of items passing along a conveyor line, which comprises directing the items to pass from the conveyor line onto a conveyor means positioned beside the line so that the items by-pass a length of the conveyor line before rejoining the latter, and weighing the items on a weight assessment device (such as a weigh load cell) included in the conveyor means.Also provided is apparatus for use in such a method comprising a conveyor means, including a weight assessment device, for location beside the conveyor line, and means for directing the items onto the conveyor means so that they by-pass a length of the conveyor line before rejoining it. The conveyor means conveniently comprises an infeed sction, for acceleration and separation of the items and an outfeed section for realignment of the items prior to their return to the conveyor line.

摘要： A totalizer apparatus, used with belt scales and other flow rate measuring devices producing output signals subject to zero drift, maintains an auxiliary totalizer register during zeroing operations so that should zero flow conditions be interrupted during such an operation, a correct total can still be maintained. This enables autozeroing operations to be implemented, for which purpose a further auxiliary totalizer is used to test for an extended absence of flow before permitting initiation of an autozeroing operation. If a zeroing operation results in an apparently excessive zero correction, it is rejected and assumed that flow has restarted during the operation; the first auxiliary totalizer register is used to update a primary register.
