    • A monitoring apparatus is provided which can ensure the prevention of a paper break even in a poor installation environment. A light source (9) illuminates light (9a) on a lateral edge (1a) of wet paper (1) and a camera (5) captures light (9b) reflected therefrom. The camera (5) is a micro camera and completely covered by a camera box (10). The camera box (10) has an observation window (10a) which is made of a transparent member, at the lens side (5a) of the camera (5). The outer surface of the observation window (10a) is coated and an air curtain (12a) that flows from above to below prevents staining caused by mist. The air curtain (12a) is formed in such a manner that air that is continuously supplied inside a cover (11) flows along the outer surface of the observation window (10a) from an opening portion (11a). A color image obtained by the camera (5) is subjected to image processing in an image processing device (6) and the resulting image is projected on a monitor TV (7), so that variations of the release point (3) can be monitored. This allows for forecasting of a machine abnormality leading to a paper break.
    • 提供了一种即使在安装环境差的情况下也能够防止纸张断裂的监视装置。 光源(9)照亮湿纸(1)的侧边缘(1a)上的光(9a),并且照相机(5)捕获从其反射的光(9b)。 相机(5)是微型相机,并被相机盒(10)完全覆盖。 相机盒(10)在照相机(5)的透镜侧(5a)处具有由透明构件制成的观察窗(10a)。 观察窗(10a)的外表面被涂覆,并且从上方向下流动的气帘(12a)防止由雾引起的污染。 空气幕(12a)形成为使得在盖(11)内连续供给的空气沿着观察窗(10a)的外表面从开口部(11a)流动。 通过照相机(5)获得的彩色图像在图像处理装置(6)中进行图像处理,并将所得到的图像投影到监视器TV(7)上,从而可以监视释放点(3)的变化 。 这样可以预测导致断纸的机器异常。

    • There is provided a monitoring apparatus for preventing paper breakage. For this monitoring apparatus, a light source 9 is disposed on the upper side of a wet paper 1, and a light emitting face thereof faces downward. An operation-side camera 5a and a drive-side camera 5b are disposed on the side opposite to the light source 9 with respect to the wet paper 1, and a lens face thereof faces upward. Light 9a of the light source 9 passes through the wet paper 1 after being reflected from a mirror 11, and is caught by the cameras 5a and 5b. Thus, the cameras 5a and 5b photograph a silhouette (image) of the light 9a of the light source 9, which has passed through the wet paper 1. This image is sent to an image processing unit 6, where the image is processed. The coordinates of a boundary line such that the wet paper 1 separates from a center roll 2 is detected from the images photographed from two directions. This coordinate value is sent to a computer 8. The computer 8 converts the value into a movement amount in each sampling cycle to determine the change amount and frequency of a separation point 3 and the whole shape of separation lines 3a and 3b. Thereby, a machine trouble resulting in paper breakage can be predicted.
    • 提供了一种用于防止纸张断裂的监控装置。 对于该监视装置,光源9设置在湿纸1的上侧,并且其发光面朝下。 操作侧照相机5a和驱动侧照相机5b相对于湿纸1设置在与光源9相反的一侧,并且其透镜面朝上。 光源9的光9a在从反射镜11反射之后穿过湿纸1,被照相机5a和5b夹住。 因此,相机5a和5b拍摄已经通过湿纸1的光源9的光9a的轮廓(图像)。该图像被发送到处理图像的图像处理单元6。 从两个方向拍摄的图像中检测出湿纸1与中心卷2分离的边界线的坐标。 该坐标值被发送到计算机8.计算机8将该值转换为每个采样周期中的移动量,以确定分离点3的变化量和频率以及分离线3a和3b的整体形状。 因此,可以预测导致纸破损的机器故障。

    • In a bandwidth management apparatus that outputs packets by observing the bandwidth set value predetermined for each destination, provisions are made to prevent a situation where the contracted bandwidth cannot be provided due to influences from packets destined for other destinations. When performing bandwidth management using token buckets provided one for each destination, each token bucket is updated by setting the upper limit token value higher when any packet is stored in the corresponding queue than when no packets are stored; this serves to prevent a situation where even when a packet has already arrived at the queue, the packet cannot be output because a packet is being output from some other queue and, as a result, unconsumed tokens are discarded at the next update time.
