Abstract: A control for loss-in-weight feeders which decreases flow error during refill of the feeder hopper. The weight range (empty to full capacity) of the hopper is divided into weight increments. Samples are taken of the hopper weight during discharge and refill, and each sample is assigned to a weight increment. During discharge, a scale factor related to the density of material in the hopper is computed, assigned to a weight increment and stored in memory; and the hopper feed screw is driven at a speed proportional to the computed scale factor. During refill, the stored scale factors are retrieved from memory and the hopper feed screw is driven at a speed proportional to the stored scale factors; but no additional scale factors are calculated.

Abstract: This relates to a method of and an apparatus for feeding a product which includes fines to a weigh hopper. In lieu of the usual feeder pan, the last feeder pan in the feeder system is a duplex feeder pan including an upper feeding pan or level and a lower feeding pan or level. The upper feeder pan is provided with selected apertures therein so that fines will be separated from the remainder of the product and directed into the lower feeder pan. During the normal filling of the weigh hopper, both the upper feeder pan and the lower feeder pan will discharge into the weigh hopper. When a pre-selected underweight condition occurs, at least a part of the product from the upper pan will be diverted from immediately entering into the weigh hopper, while the feeding of the fines will continue so as to bring the weight of the product within the weigh hopper up to the pre-selected weight with a minimum of overweight.

Abstract: In a system for dispensing weighed or counted articles, articles are fed from a supply hopper by a vibratory conveyor to maintain a controlled level of articles in a bowl-shaped feeder hopper. In a weigher embodiment, articles are initially discharged from the feeder hopper through two discharge openings into an accumulator bucket. A weighing unit monitors the weight of articles in the bucket and signals a door to close one of the discharge openings as the weight of articles in the bucket begins to approach a predetermined weight. The weighing unit subsequently signals the feeder hopper drive to slow its feeding action as the weight of articles in the bucket more closely approaches the predetermined weight. The feeder hopper discharge openings are arranged near each other at locations where the door-controlled opening will provide a rapid, bulk feed of articles, while the other opening will provide a single-file trickle feed. In a counter embodiment, a feeder hopper having a single discharge opening is used so that articles can pass single file from the feeder hopper past a counter unit to an accumulator bucket.

Abstract: 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.

Abstract: The present invention provides an automatic method and apparatus for weighing into portions. Feeding of single units is performed by separating the feeding channels for rough feeding and fine feeding so that the feeding up to the weighing station is separated. When weighed portions are too large compared to a predetermined value, the apparatus rejects the portions and returns them back to the feeding stream. By separating the stream of units into fine weighing and rough weighing, with a rejection of unsatisfied portions, the portions ccan accurately be weighed with high performance with apparatus that is both inexpensive and space saving.
