In a combination weighing apparatus, a control unit executes combination weighing processing with a second value used as a target weighing value after controlling all of the hoppers so as to discharge the article while leaving the article in the conveying unit when the second value is less than a first value in a case where the target weighing value is changed from the first value to the second value.

A mobile device (10) for measuring out at least one ingredient associated with a predetermined mass comprising: means (105) for guiding into position opposite at least one reservoir comprising an ingredient to be measured out, means (110) for reading an identifier of an ingredient on the reservoir comprising said ingredient, motorized means (115) for delivering the ingredient to be measured out from the reservoir, means (120) for acquiring a mass measurement of the ingredient, control means (125), configured to activate the motorized means when the reservoir of the ingredient to be measured out is identified by the means for reading an identifier and the device is positioned opposite the reservoir, until the mass of the ingredient acquired by the acquisition means is equal to the predetermined mass for the ingredient.

A continuous conveying type bag filling and packaging machine including multiple groups of grippers (2) continuously traveling along a racetrack-shaped annular path and, as the grippers (2) complete a single revolution, carries out various packaging operations, wherein a measuring hopper (42) is provided above each elevating hopper (37) and is continuously rotated in conjunction therewith. The measuring hopper (42) has a shutter (44). A weight detector (46), along with a shutter actuation mechanism (47), is provided so as to correspond to each measuring hopper (42) and is continuously rotated in conjunction therewith. If, based on a detection signal from the weight detector (46), it is determined that the weight of the material to be packaged that is supplied to the measuring hopper (42) exceeds the upper limit value of the allowable range, the corresponding shutter actuation mechanism (47) is not actuated, and the shutter (44) is maintained closed.

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.

The present invention relates to a guide unit for measurement acting as a guide for measuring the micro-weight of fine grains having minute weight and volume, such as powders, granules, seeds and pills, and to a micro-weight measuring system for accurately measuring the fine grains by a preset micro-weight by using the guide unit for measurement. The present invention has an effect of being capable of measuring the micro-weight as a unit to thereby package fine grains such as powders, granules, seeds and pills by micro-weight unit. In addition, the present invention has an effect of being capable of accurately measuring the fine grains by the preset micro-weight in such a manner that in the procedure of discharging a one-unit-micro-weight of the fine grains, some of the fine grains are discharged at a smaller amount than the initially-discharged amount and are finally discharged by dropping.

A method and system for correcting mass flow rate measurements relating to a conveyor used to move a stream of first component material portions to and through a mixing station in which a second component material is dispensed in a predetermined mass percentage of the mass of the first component material portions. The correction of the measurements is adapted to correct for inaccuracies that arise in the measurements due to, for example, differences in the first component material portions properties, differences in the second component material properties, environmental conditions, drift of electronic instruments, and changing conditions that occur during extended use of an upstream conveyor that delivers first component material portions to the mixing station.
