(1)目的 如外观图所示,对传送带上连续、无间隙流过的管子进行无接触方式计数。 (2)功能 (a)因为以前的光电开关计数是利用被检对象间隙中透过光线的断续性,所以如果没有间隙便不能计数,但本装置即使在被检的管子间没有间隙,只要在前进方向有高度差便可计数。 (b)限定反射式光电开关的动作原理见图。其投光轴和受光轴如图所示是交叉的。另外,由于能用外部的
(1) Purpose As shown in the figure, contactless counting is performed on the continuous, gap-free pipe on the conveyor. (2) Function (a) Since the previous photoelectric switch count is based on the intermittence of the transmitted light in the gap of the object to be inspected, it can not be counted without a gap. However, even if there is no gap between the tubes to be inspected, Height difference in the forward direction can be counted. (b) The operating principle of the reflective photoelectric switch is shown in the figure. The projection and acceptance axes are crossed as shown. In addition, we can use external
