Abstract
An apparatus for measuring weights of articles having different shapes and weights successively transported on a conveyer including first and second weighing conveyers 13 and 14 having load cells 23 and 24 to produce weight signals and photo-sensors 20, 21 and 22 arranged at inlets and outlets of the weighing conveyers 13 and 14 for detecting passage of the articles to produce article detection signals. In a calculating circuit 25, a weigh of an article is calculated by processing weight signals supplied from the first and second weighing conveyers 13 and 14 in accordance with a measuring sequence which is selected from a plurality of measuring sequences in accordance with the article detection signals supplied from the photo-sensors 20, 21 and 22. A length of an article is measured by detecting a difference (x-y) between a length of an article and a reference length Lx by which the photo-sensors 20 and 21 are separated from each other by counting output pulses from rotary encoder 15 detecting a rotation angle of driving rollers 11, and calculating a sum of the reference length and said difference (x-y).
