    • In a contact lens visual inspection method and apparatus, a contact lens insertion portion of a container is first imaged by an image pickup device and then an area which locates on the container and is unnecessary for the visual inspection of a contact lens is extracted from the image of the contact lens insertion portion to form a mask image. Thereafter, a system containing the contact lens insertion portion of the container, the preservation liquid filled in the contact lens insertion portion and the contact lens placed in the contact lens insertion portion is imaged as an inspection object by the imaging device to obtain an inspection object image, the inspection object image is overlapped with the mask image, and the mask image is subtracted from the inspection object image to set as a visual inspection area the area corresponding to a subtracting image obtained by said subtracting step. The defects of the contact lens such as soil, foreign matter, scratch, breakage, peripheral damage, etc. detected for the visual inspection area.
    • 在隐形眼镜目视检查方法和装置中,首先通过图像拾取装置对容器的隐形眼镜插入部分进行成像,然后从隐形眼镜的视觉检查中抽出位于容器上并且不需要视觉检查的区域 隐形眼镜插入部分的图像以形成掩模图像。 此后,将包含容器的隐形眼镜插入部分,填充在隐形眼镜插入部分中的保存液体和放置在隐形眼镜插入部分中的隐形眼镜的系统通过成像装置成像检查对象,以获得检查对象 图像,检查对象图像与掩模图像重叠,并且从检查对象图像中减去掩模图像,以将与通过所述减法步骤获得的减法图像相对应的区域设置为目视检查区域。 对于视觉检查区域检测到隐形眼镜的缺陷,如土壤,异物,划痕,破损,外围损伤等。

    • Automatic band strapping apparatus with a table for supporting an article during banding. An arch frame extends in the form of an upright loop from one side to another of the table. The arch frame has an elongated side wall also in the form of an upright loop in a plane substantially normal to the table. An elongated U-sectioned arch guide made of flexible plastics material such as ultra-high molecular polyethylene has a loop shape following the contour of the arch frame side wall, and one edge surface facing that side wall is opened by means of a groove. Springs press the grooved edge surface of the arch guide against the arch frame side wall thereby defining a band passage through the arch guide which is normally closed. The arch guide is locally separable from the side wall against the urgence of the springs, progressively around the length of the arch frame, providing a moderate draw-out resistance to enable release and withdrawal of band progressively and continuously from the band passage. This maintains continuous tension in the band while it is being wrapped about the article in a straight path without twisting or meandering. The plastics arch guide has sufficient flexibility in a direction normal to the side wall to enable the springs to keep it seated against the side wall despite minor dimensional variations of the parts within manufacturing tolerances. Further, the arch guide is sufficiently flexible in the direction parallel to the side wall that it will remain seated against it, and the band passage thereby kept closed against inadvertent loss of band despite local or overall self-adjusting squirming or sliding movement of the arch guide against the arch frame side wall when in use.
    • 自动带束带装置,带有用于在捆扎期间支撑物品的工作台。 拱形框架以直立环的形式从桌子的一侧延伸到另一侧。 拱形框架具有在基本上垂直于桌子的平面中具有直立环形的细长侧壁。 由柔性塑料材料如超高分子量聚乙烯制成的细长U形拱形导轨具有跟随拱形框架侧壁轮廓的环形形状,并且面向该侧壁的一个边缘表面通过凹槽打开。 弹簧将拱形引导件的带槽的边缘表面压靠在拱形框架侧壁上,从而限定通过拱形引导件的通常关闭的带通道。 拱形引导件可以根据弹簧的紧迫程度局部地从侧壁分离,逐渐围绕拱形框架的长度,提供适度的拉出阻力,以使带能够从带通道逐渐和连续地释放和退出。 这样可以保持带中的持续张力,同时以直线的方式将物品缠绕在一起,而不会扭曲或曲折。 塑料拱形导轨在垂直于侧壁的方向上具有足够的灵活性,以使得弹簧能够将其保持抵靠侧壁,尽管零件在制造公差内的尺寸变化很小。 此外,拱形引导件在平行于侧壁的方向上具有足够的柔性,使得其将保持抵靠在其上,并且带通道由此保持关闭,以防止无意中的带的损失,尽管局部或整体自调节拱形的弯曲或滑动 使用时对拱架侧壁的引导。
