Apparatus for measuring weight and length of article

An apparatus for measuring weights of articles comprising:

• a conveying means for transporting articles successively and including a plurality of weighing conveyers for measuring weights of articles successively transported thereon to produce a plurality of weight signals;
• a calculating means for receiving the weight signals supplied from said plurality of weighing conveyers and calculating a weight of each of articles by processing said weight signals in accordance with a predetermined algorithm;
• and
• an article detecting means for detecting the successively transported articles to produce article detection signals and a transporting speed detecting means for detecting a travelling speed of articles successively transported on the conveying means to produce a travelling speed signal, and said calculating means detects a length of an article by processing said article detection signals and travelling speed signal, selects one or more weight signals in accordance with the detected length of the article, and calculates a weight of the article from the selected one or more weight signals.

An apparatus for measuring weights and lengths of articles comprising:

• a conveying means for transporting articles successively along a transporting path and including a plurality of weighing conveyers arranged adjacently in series with the transporting path for measuring weights of articles successively transported thereon to produce a plurality of weight signals;
• a first calculating means for receiving the weight signals supplied from said plurality of weighing conveyers and calculating a weight of each of articles from said weight signals;
• at least two article detectors arranged with a predetermined reference length along said transporting path for detecting a passage of successive articles to produce article detection signals;
• a rotation angle detector for detecting rotation angles of driving rollers provided in said plurality of weighing conveyors to produce length signals;
• and
• a second calculating means for receiving said article detection signals supplied from said article detectors and said length signals supplied from said rotation angle detector, deriving a difference length between a length of an article and said reference length, and calculating a length of each of the articles based on said reference length and said difference length.
