Weighing apparatus

A weighing apparatus comprising:

• a transport unit configured to transport an article;
• a weighing unit connected to the transport unit, the weighing unit being configured to output a first original signal related to a weight;
• a second weighing unit located on a downstream side in the transport unit, the second weighing unit being configured to output a second original signal related to the weight,
• a weighing control unit configured to output a weighing value of the article by processing an added up original signal obtained by adding up the first original signal and the second original signal,
• wherein the weighing control unit is configured:
• to determine whether or not to adjust the zero point on the basis of a determination signal obtained by applying a first filter to the added up original signal;
• to generate an adjustment signal obtained by applying a second filter having more stages than the first filter to the added up original signal or the determination signal in a case where the weighing control unit determines that the zero point is to be adjusted;
• and
• to perform adjustment of the zero point on the basis of the adjustment signal.

A weighing apparatus comprising:

• a transport means for transporting an article;
• a weighing means connected to the transport means and for outputting an original signal related to a weight;
• and
• a weighing control unit configured to output a weighing value of the article by processing the original signal, to determine whether or not to adjust a zero point on the basis of a determination signal obtained by applying a first filter to the original signal, to generate an adjustment signal obtained by applying a second filter having more stages than the first filter to the original signal or the determination signal in a case where the weighing control unit determines that the zero point is to be adjusted, and to perform adjustment of the zero point on the basis of the adjustment signal.
