Description

光电纸张计数装置
本实用新型涉及计量检测领域。
目前,有着大量的纸张计数工作要做的印刷厂、纸张文件发放部门(如卡片、报纸图纸和地图),一般采用人工数纸的方法,效率低、易出错。
本实用新型的目的在于提供一种光电纸张计数装置,解决人工数纸效率低,易出错的缺点。
本实用新型采用如下方式实现。
本实用新型由光电传感器和计数箱构成,计数箱包括前置放大器,比较器、施密特触发器、计数器、显示器、电源和壳体。将纸张整理成扇形,在光电传感器的作用下,纸面与纸边缘就会产生强弱不同的光信号,进入光电传感器。来自传感器的光电信号经前置放大、比较、施密特触发后,变成TTL信号,进入计数器计数。
本实用新型还可以设置置数报警电路。当计数达到预置的数字后,蜂鸣器响,报警提示。
本实用新型可以准确、大量、快速统计纸张数量,每分钟可数1000张纸。本实用新型操作简单,携带方便,可用于大量分发地图、报纸、卡片、广告,甚至纸币的场合。
下面结合附图对本实用新型作进一步的描述。
附图1.本实用新型框图。其中,1-光电传感器,2-传感器支座,3-计数箱,4-前置放大器,5-比较器,6-施密特触发器,7-脉冲计数器,8-液晶显示器,9-置数报警电路,10-电源。
附图2.本实用新型电路图。其中,2(A)为前置放大器,2(B)为比较器,2(C)为施密特触发器,2(D)为置数报警电路,2(E)为电源电路,2(F)为计数显示电路。
附图3.本实用新型外形图。11-壳体。
使用时,将被计数纸张整理成间隔为1mm以上的扇形,使光电传感器(1)沿与纸边垂直的方向移动,此时,纸面与纸边缘就会产生强弱不同的光信号,进入光电传感器(1)。来自传感器的光电信号经过前置放大器(4)、比较器(5)、施密特触发器(6)后,变成TTL信号进入计数器(7)计数,并通过显示器(8)显示纸张的数量。
