The electronic balance is configured to be capable of performing the following series of operations (I) to (VII) automatically: (I) The opening and closing mechanism opens the door. (II) The moving up/down mechanism applies the load of the built-in weight to the weighing mechanism. (III) The opening and closing mechanism closes the door. (IV) After a predetermined period of time elapses, the opening and closing mechanism opens the door. (V) The moving up/down mechanism removes the load of the built-in weight from the weighing mechanism. (VI) The opening and closing mechanism closes the door. (VII) The control unit performs zero-point adjustment of the weighed value. Accordingly, operation of preliminary loading is automatically performed, and thus the stability of the weighing accuracy is improved.

It is recognized that an offset is added to a measurement value shown by a weight scale. In a case where a measurement value, shown by a body weight scale, has decreased from a first reference value by more than a first threshold, an offset determining section determines whether or not a difference between the measurement value and a second reference value is greater than a second threshold. In a case where the offset determining section determines that the difference between the measurement value and the second reference value is greater than the second threshold, the offset determining section stores the measurement value as a candidate second reference value.

A combination weighing device 1 includes: a plurality of weighing hoppers 6 which receive articles supplied from an outside, weigh the articles, and discharge the articles; a plurality of booster hoppers 7 which are respectively disposed right below the plurality of weighing hoppers 6 and receive the articles discharged from the weighing hoppers 6; and a control unit 20 which calculates a combination of weighed values so that a total value becomes a target value from a plurality of weighed values respectively correlated with the weighing hoppers 6 and the booster hoppers 7, in which the control unit 20 extracts the weighing hopper 6, corresponding to the booster hopper 7 having the article existing therein and capable of using the weighed value of the article in next combination calculation, as a zero-correction target.

An electronic scale includes a display unit for digitally displaying the weight of a load on a weighing dish, a tare subtraction key, a display control unit for controlling the display on the display unit and a memory for memorizing a zero adjustment range. The display control unit displays on the display unit a tare subtraction prompt display for prompting to push the tare subtraction key when the measurement value of the load increases over the upper limit of the zero adjustment range.

A weighing system and method for refillable containers. A control system includes one or more processors and at least one memory configured to store user data associated with a user, the user data includes biometric data indicative of a biometric identifier of the user and container data indicative of an empty container weight. The control system is configured to: receive a request to weigh a product in a container; receive captured data indicative of the biometric identifier from a biometric capture device; output a control signal to control a scale to weigh the product in the container; receive, from the scale, weight data indicative of the weight measured by the scale; identify the container data associated with the user by comparing the captured data to the biometric data stored in the memory; and determine a corrected weight of the product in dependence on the weight data and the container data.

The present invention relates to a system (1a; 1b; 1c; 1d; 1e) for preparing foods (100), comprising a housing (10) for receiving the food (100), a recognition device (20) for recognizing at least one food carrier (200) couplable with the system (1a; 1b; 1c; 1d; 1e), and thereby recognizing the weight of the food carrier (200), as well as a determining device (40) for determining the tare weight of the food based on the detected weight of the food carrier (200).

A weigh/fill type box filler for cherries, cherries and similar small produce that incrementally moves and fills an array of individual packaging bags within conventional packing boxes. The box filler includes a box conveyer, a producer conveyer, a metering gate, a weigh/fill scale assembly and three independent box lifters. The box conveyer moves the packing boxes incrementally over the weigh/fill scale assembly to position each row of bags within successive packing boxes beneath the metering gate. As one packing box is incrementally moved across the weigh/fill scale assembly and each row of bags is weigh/filled, the box lifters sequentially raise the adjacent preceding and following packing boxes out of contact with the weigh/fill scale assembly. The metering gate uses independently actuated gate paddles to selectively control the flow of produce into the individual bags first at a high volume gross fill rate and finishing with a lower volume or fine fill rate.
