  • Patent number: 8735746
    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.

  • Publication number: 20110079448
    Abstract: An automated weighing and filling station that operates without slowing the primary feed transfer. The system includes a bulk product supply, such as a hopper. A primary feed system delivers the product from the bulk product supply to the weighing station which includes two or more independent scale weigh hoppers with a diverter system operating between the two scale weigh hoppers. Each of the scale weigh hoppers empties into a discharge hopper. The primary feed system delivers the product to the diverter system at a constant speed. The diverter system delivers the product from the primary feed system to a first of the scale weigh hoppers until the scale weigh hopper anticipates that the determined weight will be achieved. At that time, the diverter moves the product from the primary feed system to the second of the scale weigh hoppers. The flow of product from the primary feed system is not slowed or stopped, but continues to operate at a constant speed.

  • Patent number: 7868260
    Abstract: There is disclosed an apparatus and method which is capable of dispensing very small (typically less than 5 mg) quantities of particles to a high accuracy in a repeatable way and without undue wastage. Also, the need for advanced particle formulation is reduced. The apparatus comprises a closed loop control system which uses an electro-mechanical actuator to deliver impact energy to a supply of particles initially held on a sieve in a hopper. The impact energy causes a small number of particles to fall through the sieve and onto a weight measuring balance. The weight obtained is scrutinised by a processor to see if further actuations are required. In preferred embodiments, the energy of actuation is varied in accordance with the rate of dispensation calculated by the processor. Also, a correction amount can be obtained to take account of the fact that the balance can take a considerable amount of time to settle to its final value.

Control is passed to step S2 and step S3 and a numerical value A at the digit of thousand is displayed. After the putting in is continued, in step S5, S-W<1000 is obtained. Control is passed to step 56 and step S7, where in addition to the numerical value A of the digit of thousand, a numerical value B of the digit of hundred is also displayed while ignoring the numeric values C and D of the digits of ten and one. In step S8,S-W<100 is obtained. Control is passed to step S9 and step S10, where in addition to the numerical values A of the digit of thousand and the numerical value B of the digit of hundred, the numerical value C of the digit of ten is also displayed while ignoring the value D of the digit of one.

  • Patent number: 7368671
    Abstract: A Vacuum conveying apparatus with a weighing and metering device, comprises a separation container (10), acted on by a vacuum, for intermittent intermediate storage of material conveyed in a suction gas flow, a force isolation means for entry of conveyed material into the separation container (working side), a weighing device (50) for, in particular, continuous weighing of the separation container, as well as a vacuum pump (70) and a controller. In order to create a vacuum conveying apparatus that can guarantee a more precise weighing and/or a more accurate stipulation of the timepoint for turning off the vacuum pump or for interrupting the suction process during the ongoing conveyance process, the vacuum pump (70) is isolated in terms of force from the separation container (10) and is also situated such that it is not weighed.

  • Patent number: 7358451
    Abstract: There is disclosed an apparatus and method which is capable of dispensing very small (typically less than 5 mg) quantities of particles to a high accuracy in a repeatable way and without undue wastage. Also, the need for advanced particle formulation is reduced. The apparatus comprises a closed loop control system which uses an electromechanical actuator to deliver impact energy to a supply of particles initially held on a sieve in a hopper. The impact energy causes a small number of particles to fall through the sieve and onto a weight measuring balance. The weight obtained is scrutinised by a processor to see if further actuations are required. In preferred embodiments, the energy of actuation is varied in accordance with the rate of dispensation calculated by the processor. Also, a correction amount can be obtained to take account of the fact that the balance can take a considerable amount of time to settle to its final value.

  • Patent number: 7282651
    Abstract: A system for weighing items sequentially delivered by a feeder subsystem in order to discharge batches of items having a desired target weight; and more particularly to a method and apparatus particularly configured to handle fragile items, e.g. strawberries, cherries, etc., to reduce bruising such items during the weighing process. The invention includes a container for receiving discrete items sequentially delivered by an item feeder together with means for measuring the weight of items accumulated in the container. The weighing container is located for movement between a first position at which a product receiving surface is oriented substantially horizontally in close proximity to the output location, for receiving product items from the output location, and a second position at which the container is oriented to accommodate an increased volume of items. The weighing apparatus includes means for moving the container from the first position to the second position and discharging the target weight of items.

  • Patent number: 7211746
    Abstract: A weigh-pan metering and blending apparatus having a holding chamber for receiving fiber from a fiber distributer and providing temporary storage of the fiber. The metering chamber meters the fiber received from the holding chamber, wherein the metering chamber includes at least one discharge device for advancing the fiber to diverter doors pivotally mounted at one end of the metering chamber for oscillating movement between first and second downstream delivery openings. First and second weigh-pans communicating with respective ones of the first and second downstream delivery openings receive the fiber from the metering chamber. First and second discharge chambers receive the fiber from respective ones of the first and second weigh-pans, wherein the first and second discharge chambers include a discharge device for advancing the fiber to adjacent transfer ducts for discharge.

  • Patent number: 7196276
    Abstract: A truck-mounted scale mechanism can provide an accurate measurement of the weight of loose material dispensed from a delivery truck. The scale mechanism is supported on the tailgate of the delivery truck for transport from one job site to another. A winch provides a mechanism for deploying the scale mechanism from the transport position. The scale includes a frame mechanism pivotally supporting a hopper having a gate-controlled discharge chute operated by an air cylinder with weigh cells being located between the hopper and the frame. A computer on the scale mechanism operatively controls the air cylinder controlling the gate on the delivery chute of the truck bed and the air cylinder controlling the discharge chute gate on the hopper such that the loading, weighing and dispensing of the loose salt from the truck bed to the customer storage facility is automated until the system is halted by the operator.
