Abstract

由一个显示发生器产生光强变化率对容器数的 关系曲线，再沿该曲线确定一阈值的位置，以便将合 格的容器与不合格的容器分离开来。再由一个拒收 控制器接收这个阈值数据，并将光强度变化率较高的 容器抛弃。

Description

本发明涉及检验玻璃容器成品的裂缝用的检验机。
玻璃容器成品可能会含有叫做裂缝的缺陷，这种缺陷是不能容许的。因此每一个容器是要经过检验，以确定有无这类缺陷存在，具体作法是用光照射容器，检测这类缺陷所引起的异常反射。容器表面合格时，它使反射生产这样变化：该表面所反射的光基本上比有缺陷的表面所反射的光少。
反射光由传感器检测，光强变化再转换成表示光强变化率的数字信号。然后再由操作人员选取一个阈值，以作为电子控制器鉴别玻璃容器合格与否的依据。
本发明的目的是简化这个阈值的选择工序。从本说明书的下列部分和根据专利法规的指示来解释结合本发明原理的目前最佳实施例的附图，可以了解本发明的其他目的和优点。
现在参看附图。
这一幅唯一的附图是按照本发明的教导制造的检验机的原理图。
玻璃容器成品可能会有象裂缝之类的不能容许的缺陷。为确定哪一些容器不合格，令光源的光照射到待检验的玻璃容器上，并由一个传感器接收从容器反射回来的光。再用一个微分器确定传感器模拟输出的微分值。对于每一个玻璃容器都要用模/数将微分器的峰值输出（此输出表示反射光的光强度变化率）转换成数字形式，然后加到一个分级器，如多路转换器上，由该分级器将其归类到其中一个所选定的光强等级值。对于每一次分类，相应的计数器就被修正，同时显示发生器就将此数据以光强对容器数的X-Y曲线图的形式显示在CRT（阴极射线管）荧光屏或其它类似的装置上。该曲线图显示于CRT荧光屏上。从图中可看出，合格容器的反射变化率小于具有象裂缝之类的缺陷的容器，同时该曲线给操作人员提供了一幅直观图象，简化了他确定区分容器好坏的界限位置的任务。操作人员可以在沿光强轴线上他认为是合格与不合格容器之间的分界点的任意位置确定阈值线。
按压动态阈值设定器的上行或下行按钮10使该阈值线移动时，该点沿曲线的光强就在荧光屏上显示出来。操作人员最后确定该阈值线的位置时，光强的阈值（在这里为182）就最后确定下来，于是拒收控制器就将所有光强值变化率较高的容器抛弃。
