Abstract

PURPOSE:To eliminate loss time in measurement during manufacturing, conveyance ad the like, to reduce a maintenance cost and to make it possible to measure the entire length of an objective body, by providing a tip detector, which can detect the entire area of the cross section of a rod shaped running body to be measured, and providing a measuring device, which measures a distance from the detector and the rear end surface of the running body. CONSTITUTION:A material to be measured 1 is sent on a conveying rollers 2 sequentially in the direction perpendicular to the surface of paper and moved in the direction of an arrow. When the tip of the material to be measured reaches a detecting zone 9, the face is detected with a light projector 3 and a tip detector 5 comprising an image sensor camera 4, which are provided between the rollers 2. At this time, the detecting zone 9 is made to have the size so that the entire area of the cross section of the material to be measured 1 can be detected. Even if the shape of the tip is pointed or has irregularities, the tip can be detected correctly. A distance measuring sensor 6 is provided at a specified distance L from the detecting zone 9. A distance l0 between the rear end surface of the material to be measured and the sensor 6 is measured with a distance measuring device 7 having the distance measuring sensor 6 at the same time. The distance l0 is subtracted from the distance L with a length operating device 8, and the result is displayed and outputted 10.

[Operation] Since the tip detector is capable of detecting the entire cross section of a traveling object, it is possible to correctly detect the tip even if the tip is sharp or uneven. Furthermore, since the side range device that measures the distance to the rear end surface of a running object has a large measurement range, even if the length of the object to be measured increases, only one device is required, reducing equipment costs. Furthermore, the leading edge detector is naturally provided between the conveyor rolls, and the side track device is not affected by the conveyor rolls, so there is no equipment restriction.
