A reel weight measurement system is shown and described herein. In some embodiments, the reel weight measurement system comprises strategically placed position and load sensors for measuring an orientation of a reel-carrying unit and measuring loads in the reel-carrying unit. The loads may be indicative of forces due to the weight of the reel when the reel is supported by a carriage of the reel-carrying unit. The weight of the reel may be determined by summing the forces and moments in the system while the carriage is in motion or static. Further, the weight of the reel may be determined by comparing the force measurements and orientation of the carriage to stored calibration data.

The automatic calibration device for integrating conveyor belt scales (100) is incorporated to a mounted-type integrating conveyor belt scale, mounted to bulk material conveyors, featuring a structure that supports racks with rolled cylinders, which, when assembled, are able to support the conveyor belt; the automatic calibration device (100) with the movement mechanism, comprised in this implementation, by a pair of parallelograms comprised of the beams (1) and (2) connected by rotating joints (7), (8), (9), (10) to the minor arms, (22), (23), (24), (25) which, in turn, are connected to the parallel shafts (3) and (4), with the distances between centers being equal to the distance between rotating joints of the beams; an actuator (14) is used to move standard weights (11) and (12), initially supported onto cavities (16), (17), (18) and (19) provided on the beams (1) and (2) of the parallelograms, until reaching the berths (30), (31), (32) and (33) connected to the weigh bridge (41) of the scale.

A weigh-in-motion scale system for a linear synchronous motor conveyor and a method for weighing objects on a linear synchronous motor conveyor are described herein. In one embodiment, the weigh-in-motion scale system includes a support structure for supporting the following: a weigh cell, a section of a linear synchronous motor conveyor track, a vehicle for transporting an object, and an object; and a weigh cell on the support structure on which a section of a linear synchronous motor conveyor track rests directly or indirectly. In one embodiment, the method includes transporting a vehicle with an object thereon along a section of a linear synchronous motor conveyor track; and at a weighing station while the vehicle with the object thereon is being transported, weighing the section of a linear synchronous motor conveyor track, vehicle, and object to determine the weight of the object.

In a dynamic scale for flat goods on their sides, and a control method therefor, flat goods are transported with a continuous counting of encoder pulses, and a weight measurement of a moving flat good is started when the trailing edge of the flat good has reached a first sensor. A first count state of the counter is stored when the leading edge of the flat good reaches a second sensor but a valid weight measurement result is not present. A weight measurement takes place with a transport velocity reduced in steps. After a step-down of the transport velocity of the flat good a subsequent weight measurement is performed with a next lowest transport velocity, and the current counter state is then queried if neither a valid weight measurement result exists, nor can it be established that the trailing edge of the flat good has reached the first sensor, although the leading edge of that flat good has reached the second sensor, as well as a check shows the current counter state corresponds to the sum of the stored counter state and a predetermined count value. The querying steps after the check are repeated as long as the current counter state has not yet reached the sum, and with an additional step-down of the transport velocity of the flat good and weight measurement result, until the check shows the current counter state has reached the sum.

An integral weighing and sorting system that weighs articles on a roller belt and selectively actuates or deactuates belt rollers to divert selected articles. After an article is weighed on the roller belt, its weight is compared to a predetermined weight range. Out-of-range articles are directed to exit the belt via a different route from that of in-range articles by actuating the rollers to rotate in a direction transverse to the travel direction in a roller-actuation zone.

A method of determining a mass flow rate, volumetric flow and test weight of grain during harvesting operations. A sensor is disposed in the harvesting machine against which clean grain piles are thrown by the clean grain elevator flights. The sensor changes the direction of the clean grain pile such that each clean grain pile compresses into a substantially discrete, contiguous shape producing discrete grain forces resulting in discrete signal pulse magnitudes generated by the sensor. The mass flow rate is calculated by summing the signal magnitudes and dividing the summed magnitudes by the sampling period. The volumetric flow rate is calculated by multiplying the pulse width generated by the sensor by a multiplier which relates pulse width to volumetric flow. The test weight of the clean grain is calculated by dividing the mass flow rate by the volumetric flow rate.

A first sensor combined to a first storage carrier for the material for detecting vibrations associated with offloading the material and a second sensor for measuring the weight of the material expelled from the first storage carrier.

In an embodiment, the present invention provides a weighing and labeling conveyor for labeling articles, the articles including a first application point at a same point on the article, the conveyor including: a weighing conveyor for determining the weight of the articles; a transport apparatus for transporting the articles; and a labeling system for labeling the articles, the labeling system including three labelers, each labeler including an applicator, each applicator being suitable for applying a label to the first application point on an article while the article is being transported on the transport apparatus. Of the three labelers, during normal operation two labelers are in an active operating state and one labeler is in a passive operating state. During normal operation, the two labelers that are in the active operating state alternately label the first application point of successive articles.

A diverting checkweigher comprising a conveyor belt with product-carrying, vertically floating slats that are supported on a weigh scale as the belt passes over it. The floating slats isolate product weight from belt weight. The slats themselves may be laterally stationary or divertible. If divertable, they can divert products based on their weights. If not divertible, the slats can be used with product pushers to divert products for weight-based sorting or rejection. The slats have legs that extend below the bottom of the belt to ride on the scale or be diverted across the belt by a diverter. The pushers are diverted by a diverter.
