    • A sensor (10) for sensing and counting objects on a moving conveyor (12). Objects (11) are moved on the conveyor (12) past a sensor having first and second legs (18, 20) pivotally mounted about a fixed axis above the conveyor (36, 38). The second leg is offset from the first leg in the direction of conveyor movement (13). As an object encounters the first leg, it causes the first leg to rotate toward the second leg. A proximity detector includes a target mounted on the first leg and a sensing element mounted on the second leg. The proximity detector detects movement of the first leg relative to the second leg and generates a pulse, thereby counting the object, when the first leg assumes a predetermined position relative to the second leg.
    • 一种传感器(10),用于感测和计数移动传送器(12)上的物体。 物体(11)在传送器(12)上移动经过传感器,该传感器具有围绕传送器(36,38)上的固定轴线可枢转地安装的第一和第二腿部(18,20)。 第二腿部沿着输送机运动方向(13)偏离第一腿部。 当物体遇到第一条腿时,它使第一条腿向第二条腿转动。 接近检测器包括安装在第一腿上的靶和安装在第二腿上的感测元件。 接近检测器检测第一腿相对于第二腿的移动,并且当第一腿相对于第二腿呈现预定位置时产生脉冲,从而对物体进行计数。

    • An apparatus for counting the sheets of a stream of partly overlapping sheets wherein the leaders of the next-following sheets normally rest on the trailing ends of the preceding sheets has a transporting unit which defines a path having two mutually inclined portions with the second portion sloping downwardly at an angle of 15 to 90 degrees relative to the first portion so that the leaders of successive sheets are lifted off the trailing ends of the respective preceding sheets. A photocell generates signals on detection of successive leaders while the leaders are on their way from the first into the second portion of the path, i.e., while the leaders are separated from the trailing ends of the preceding sheets, and such signals are transmitted to a counter which regulates the conversion of sheets into a series of stacks containing preselected numbers of superimposed sheets. The photocell is installed substantially midway between the longitudinal marginal portions of the stream. The sheets which travel past the photocell are subjected to the deforming action of an endless belt or chain which causes the upper sides of the sheets to assume a concave shape with the deepmost portion of each sheet extending in parallelism with the direction of transport of the stream.
    • 一种用于对部分重叠片材的片材进行计数的装置,其中下一张纸张的前导件通常搁置在前一片材的后端上,该传送单元限定具有两个相互倾斜的部分的路径,第二部分倾斜 相对于第一部分以15至90度的角度向下倾斜,使得连续片材的引导件从相应的前述片材的后端提起。 领导者在从路径的第一部分到第二部分的途中,即领导者与前面的片段的尾端分离时,光电管元件在检测到连续的领导者时产生信号,并且这些信号被传送到 计数器可调节将纸张转换成包含预选数量的叠加纸张的一系列堆叠。 光电池基本上安装在流的纵向边缘部分之间的中间。 穿过光电管的片材经受环形带或链条的变形作用,其使得片材的上侧呈凹形,每片的最深部分与流动方向平行延伸 。

    • The disclosure relates to an air pressure sensor comprising a first air passage, a branch passage having an opening into the air passage, a sensor in the branch passage responsive to variation in air pressure in the opening and jet means for air flow through the first passage adjacent the opening to the branch passage to create an increased depression in static pressure as compared with the remainder of the air passage to enhance the response of the pressure sensor in the branch passage when air flow through the first passage occurs. The air passage terminates in a probe having an orifice to be opened and closed by the absence of and presence of a surface in contact with the probe so that the pressure sensor indicates whether or not the probe is in contact with the surface. The arrangement is particularly suitable for counting a "shingled" stream of sheets such as signatures, the stream passing the orifice to the probe such that the orifice is opened and closed as successive sheets pass the probe, the resulting signal in the air pressure sensor being used to operate a counting device.
    • 本发明涉及一种空气压力传感器,其包括第一空气通道,具有通向空气通道的开口的分支通道,响应于开口中的空气压力变化的分支通道中的传感器和用于通过第一通道的气流的喷射装置 与分支通道的开口相邻,以产生与空气通道的其余部分相比增加的静压压力,从而当气流通过第一通道时增强压力传感器在分支通道中的响应。 空气通道终止于具有孔口的探针,其通过不存在和存在与探针接触的表面而被打开和关闭,使得压力传感器指示探针是否与表面接触。 该装置特别适用于计数诸如签名的片状流,流经该孔的流到探针,使得当连续片通过探针时孔被打开和关闭,空气压力传感器中产生的信号为 用于操作计数装置。
