  • Patent number: 9321598
    Abstract: It is an object of the present invention to provide a conveyor which estimates weight of a transport object while it is carried without using devices such as a load cell which directly measures weight. The conveyor has a plurality of zones forming a series of carriage ways. An approach-run zone and a weight-measurement zone are arranged adjacently in the conveying direction and are provided with different drive motors. The drive motor of the approach-run zone and the drive motor of the weight-measurement zone are controlled with respectively different predetermined rotation speeds as their target rotation speeds. A rotation speed sensing means obtains the change of rotation speed of the drive motor in the weight-measurement zone when a transport object is conveyed into the weight-measurement zone from the approach-run zone, and a weight sensing means then calculates the weight of the transport object based on the change of the rotation speed.

  • Publication number: 20150122554
    Abstract: The invention provides a method for check weighing of materials and a check weighing device thereof. Accurate weighing of materials is achieved through physical deformation of a sensing device (1) caused by a vertical downward force. When the induction device (2) detects the materials, the main transmission device (30) stops rotating and the vertical downward force on the weighing device transferred to the suspension mechanism (50) through the weighing device (40). The sensing device (1) deforms under the action of vertical downward force exerted by the suspension mechanism (50) to determine the weight of materials. Comparing prior weighing readings of materials after being proportioned with weighing readings of check weighing, the main transmission device (30) drives the materials to continuously move, the process of check weighing of materials is accomplished.

    Abstract: A method for operating a weighing apparatus and system contemplates that the system is operated in a ratio of two modes of operation, including a first, non-sampling mode, and a second, sampling mode. Operating in the first mode, wherein verification of a dose weight is not effected, promotes high cycle rates. Operation in the second, sampling mode requires operation at a slower cycle rate, but permits optimization of the accuracy of the overall weighing process. Operation in the two modes of operation, and adjustment of the ratio of the modes of operation, promotes optimization of weighing accuracy and cycle speeds.

    Abstract: A fiberglass strand measuring device is provided for the open mold process. The device is configured to mount on the exterior of the chopper air motor, which is customarily occupied by the motor end cap. This invention provides a method to measure strand fiberglass without directly contacting the raw material. The indirect measurement is accomplished by attaching a standoff with a magnet to an armature of a motor. Rotation of the armature results in rotation of the standoff and thus circular motion of the magnet. Each rotation can thus be detected by a hall effect sensor as the magnet passes the hall effect sensor. The weight of the strand fiberglass can then be calculated using a provided linear density. A handle can be included to provide additional stability and support for an operator of the chopper gun. The device becomes an integral part of the chopper gun requiring no maintenance.

  • Patent number: 8247711
    Abstract: An intermittent motion checkweigher for weighing products of interest. The checkweigher includes a product transport wheel having a plurality of product retention pockets, each of which retains one or more products of interest throughout the weighing operation. Products are loaded into a product retention pocket by an in-feed conveyor or similar device, after which the product transport wheel is indexed to advance the products in the product retention pocket toward one or more weighing devices where the products will be weighed while still located in the product retention pocket. After weighing, the products are advanced to a discharge conveyor or similar device by further indexing of the product transport wheel.

  • Patent number: 8097213
    Abstract: Material delivery systems, methods of delivering material and methods of calibrating such systems and methods are disclosed. The material delivery system includes a delivery vessel, a load cell, and automated weight calibration device. The delivery vessel has at least an outlet adapted for coupling to an unit. The load cell is configured to provide a metric indicative of an amount of material in the delivery vessel. The automated weight calibration device is configured to impart a known force onto the at least one load cell. A method includes delivering material to a unit and determining how much material is delivered by a change in weight of a delivery vessel, wherein the delivery vessel comprises a load cell; applying a known calibration force to the load cell; and comparing a metric from the load cell of the known calibration with an expected metric.

  • Patent number: 8055456
    Abstract: An interior space of the at least one housing of a force-measuring device is filled with a gas composition that is distinguishable in at least one parameter from the ambient atmosphere. A sensor that is arranged in the interior space, or on the housing, measures this distinguishable parameter. A processing unit of the force-measuring device compares signals obtained from the sensor to monitor and determine the condition of the force-measuring device.

  • Publication number: 20110232972
    Abstract: Systems and methods for reducing erroneous weighing of items such as by detecting items extending beyond a periphery of a weigh platter whereby in one configuration, the system employs a light guide for routing a light beam to a detector operative to detect interruption of the beam due to an item encroaching upon or overhanging an edge of the platter. In another configuration, the scale includes a perimeter gap between the platter outer edge and scanner housing frame or checkout counter, a light beam directed angularly upward through the gap is partially obstructed by the frame and platter whereby light exits the gap forming a light plane, wherein an object placed on the platter extending across the gap intersects the light plane thus scattering light rays, some of which are sensed by a detector. Various indicators for alerting the operator of off-scale detection are also described.

  • Patent number: 8022316
    Abstract: A force measuring device, especially a weighing device, has at least one force-measuring module that includes a force-measuring cell, a communication means, a terminal and at least one communication line, through which communication signals are transmitted between the terminal and the communication means. In a method for determining the condition of such a device, at least one voltage present at the communication line or at the communication means is measured. The measured value, or a processed result therefrom, are transmitted through the communication line to the terminal. A parameter representing the condition of the force-measuring device is determined from the measurement value, or the processed result, in an accurate and simple manner.

  • Patent number: 7872201
    Abstract: A programmable weighing scale and a system and method for programming values of adjustable operating parameters used in generating the displayed output from the weighing scale. The weighing scale is placed into a restricted-access programming mode, which allows an authorized programmer to select values of operating parameters that allow the programmer to initially set or change the service characteristics of the scale. Operating parameters that can be varied include variables used in sampling the weighing scale's transducer electrical output, mathematically processing that output, and displaying the results. Once the operating parameter values have been selected, the weighing scale will utilize those values until the weighing scale undergoes a subsequent reprogramming.
