  • Patent number: 10690534
    Abstract: A weighing conveyor system, a checkweigher, and a method for weighing conveyed objects with a checkweigher comprising LIM-driven rollers positioned in a conveying line and position sensors for determining the objects' weights from the motion of the objects across the rollers. The LIM drives the rollers with a constant torque. The acceleration of an object driven by the rollers is inversely proportional to the object's weight. So an object's weight can be determined by the effect of the rollers on its motion.

    Abstract: In a dynamic scale and control method for flat goods transported on their sides, use an input-side first assembly for thickness measurement, a transport device having transport belts arranged on a weighing plate. A control processor starts a length measurement and the driving of the transport belts, and starts a thickness measurement and implement a dynamic weighing process during the transport of a first flat good. A next flat good is supplied to the input of the dynamic scale if a valid weight measurement result is present for the predecessor good, and ejection of the predecessor good or end of the weight measurement occur if a third sensor at the input of a takeoff device of the dynamic scale detects the leading edge of the predecessor good, and a check yields that no valid weight measurement result is present for the predecessor good.

    Abstract: A system and method for calculating the weight of a load over a conveyor belt system. The method comprises placing a material that has a weight onto a conveyor belt, moving the conveyor belt at a desired speed, and calibrating a weight meter to solve for the coefficients of a polynomial equation. The method then comprises operating the motor drive to send a desired power supply signal to the motor. The motor drive sends command signals to the motor to move the conveyor belt at the desired speed. The weight meter inputs the power supply and speed signal data as well as the coefficients calculated in the calibration into a polynomial regression formula to calculate for the mass of a load on the conveyor belt in which mass is a function of the power and speed. The weight meter outputs the mass calculation to the other system components.

  • Patent number: 8188384
    Abstract: One problem with weighing conveyors is that the tension of the conveyor belt, needed to allow the belt to be driven, inadvertently reduces the degree of sagging of the belt caused by the mass of the product on the belt, which affects weighing accuracy, as this pre-tensioning of the belt inadvertently supports some of the weight of the product being transported, and this tension supported fraction of the weight cannot be sensed by the load cell supporting the middle section of the belt. In a preferred embodiment, a flexible transition area is formed in-between the outer edges of the belt and the middle, product transport area, wherein the transition area comprises openings that serve to weaken the belt locally, such that a pre-tensioning of the middle part of the conveyor belt is reduced; this allows the middle part of the conveyor belt to hang substantially slack even as the outer edges of the conveyor belt are driven.

The conveying units are arranged around a periphery of the dispersion unit. The weighing units are arranged around a periphery of the conveying units. Each of the conveying units includes a trough. At least one of the troughs has a cross-sectional diameter that gradually increases generally from the inside end to the outside end so that the one of the troughs and an adjacent one of the troughs are kept in contact with each other from the inside ends to the outside ends. At least one of the conveying units has a spiral member disposed over a bottom surface of the trough. The spiral member is configured and arranged to convey the product material supplied from the dispersion unit toward the outside end of the trough.

  • Patent number: 7569778
    Abstract: An arrangement for conveying product material to a weighing system includes an infeed for product material to be weighed and at least one dosing mechanism for controlled conveying of product material portions from the infeed to a weighing system. The dosing mechanism includes a motor-driven transport screw formed as a helically-shaped rod positioned in an open trough for conveying the product material from the infeed to the weighing system, and a control unit for controlling the motor in order to deliver a desired portion of product material to the weighing system. This arrangement provides a gentle, well-defined conveyance of product materials that are not suited for vibrational conveyance or conveyance by a screw conveyor in a tubular housing.

  • Patent number: 7534970
    Abstract: A system and method of measuring and dispensing material in a container is disclosed. The system may comprise a container, a feeder, a frame, a first sensor, and a second sensor. The container is configured to contain the material. The feeder receives and conveys material from the container. The frame is pivotal about a pivot and supports at least the container. The first sensor produces a signal representative of at least a weight of a portion of the material in the container. The second sensor produces a signal representative of the weight being applied to the pivot or fulcrum, which may be a portion of the weight within the container. A device sums the weights detected by the first sensor and the second sensor.

  • Patent number: 7531758
    Abstract: An apparatus for weighing and labeling of a product in a high speed processing environment includes an entry conveyor having an entry end and an exit end. A weighing conveyor has an entry end for receiving the product from the exit end of the entry conveyor and an exit end from which the product is delivered from the weighing conveyor. The weighing conveyor is operatively mounted to a weighing device to produce product weight information for the product being transported on the weighing conveyor. The weighing conveyor includes a first conveyor member extending from the entry end to the exit end of the weighing conveyor and a second conveyor member extending from the entry end to the exit end of the weighing conveyor. The first and second conveyor members operate cooperatively to convey the product from the entry end toward the exit end.

  • Publication number: 20090025986
    Abstract: Proposed are a weighing device for a packaging machine and a method for weighing packages from a packaging machine, which can be realized in a space-saving manner and/or permit the processing of packages within a large spectrum of package formats. This is achieved according to the invention in that the weight of two or more packages (7?, 7?) and the weight which is changed as a result of the subsequent supply or lead-away of an individual package (7?) or of a number of packages which are to be weighed together are measured, with it being possible for the weight of an individual package (7?) or of a number of packages which are to be weighed together to be determined from the difference between the weights which are determined in this way.

  • Patent number: 7439454
    Abstract: A transport apparatus that enables a trough to be easily removed in one step, and a combination weighing apparatus provided with the same are provided. The transport apparatus includes a trough and a reciprocating movement mechanism, and is configured to convey an article placed in the trough in a predetermined direction. The reciprocating movement mechanism includes a motor box, and a support member. The trough has one of a protruding part and a depressed part, while the support member had the other of the protruding part and the depressed part. The motor is configured to move the trough via the support member along the conveyance direction such that the trough moves faster in a direction opposite the conveyance direction than in the conveyance direction. The protruding part is removably connected to the depressed part.
