DIMENSION MEASURING DEVICE, VOLUME MEASURING DEVICE AND VOLUME DENSITY MEASURING DEVICE FOR ARTICLE

摘要

PURPOSE: To measure the times related to the carrying speed of an article and the width, height and length of the article during the carrying of the article, and precisely measure the dimension of the article by the operation from each measured time. ;CONSTITUTION: While a carrying device 12 carries an article 13 along a prescribed carrying route, a length measuring photo beam switch 14 first detects the article 13 under carrying. Thereafter, each measuring photo beam switch 15, 16, 17 for measuring the carrying speed, width and height detects the article 13, and the switch 14 is laid in non-detecting state. On the basis of the time when the switch 14 is ON, the times related to the carrying speed and the width and height of the article 13 until the switches 15, 16, 17 are ON, and the time related to the length of the article until the switch 14 is laid in the non-detecting state are measured by a time measuring part. A dimension arithmetic part calculates each dimension (width, height, length) of the article on the basis of each measured time. Namely, the longer (shorter) the dimension, the shorter (longer) the time related to the dimension, and a precise measurement can be performed.;COPYRIGHT: (C)1995,JPO
