Description

纸币清分机和薄片类介质处理装置
本申请要求2014年06月16日提交至中国知识产权局的、申请号为201420319618.X、名称为“纸币清分机和薄片类介质处理装置”的中国实用新型专利申请的优先权，其全部公开内容结合于此供参考。
技术领域
本发明涉及一种纸币清分机和薄片类介质处理装置。
背景技术
纸币清分机用于对纸币进行鉴伪、清点或分类等处理操作。如图1所示，常见的纸币清分机内设置有输送通道18'，在输送通道18'的起始端设置有入币口14'，沿输送通道18'设置有用于将入币口14'处放置的多张纸币中位于最下层的纸币一张一张地送入输送通道18'内的输送辊组16'和用于识别、计数纸币的识币计数部20'，在输送通道18'的末端分成两个支路，一个支路与出币口30'连通，另一个支路与退币口40'连通，其中，在退币口40'处设置有检测机构，用于检测退币口40'处是否存在纸币。检测机构包括光发生器42'和光接收器44'，其中，光发生器42'设置在退币口40'的顶板上，光接收器44'设置在退币口40'的托板上，两者相对设置，当退币口40'没有纸币时，光发生器42'发出的光线被光接收器44'接收，光接收器44'输出第一信号，当纸币被送至退币口40'堆放在托板上时，光发生器42发出的光线被纸币遮挡，不能被光接收器44'接收，光接收器44'输出第二信号，据此纸币清分机的控制器可以判断退币口40'是否存在纸币。
由于这种检测机构只能检测退币口40'内是否有纸币，当送至退币口40'的纸币超出退币口40'的容量并且没有被及时取走时，如果继续退币，有可能发生退币口40'堵塞，使纸币卡塞在支路上，引起设备故障。因此，现有技术中，关于如何设置用于检测退币口是否将要堆满纸币的检测机构，尚未提出有效的解决方案。
发明内容

进一步地，上述至少一个出币口包括第一出币口和第二出币口，独立辅通道包括连接第一出币口和主通道的第一辅通道以及连接第二出币口和主通道的第二辅通道，其中，换向机构包括位于第一辅通道和主通道之间的第一换向机构以及位于第二辅通道和主通道之间的第二换向机构。
本发明的另一方面提供了一种薄片类介质处理装置，包括薄片类介质的堆叠存放部，堆叠存放部包括相对设置的托板和顶壁，顶壁上设置有反射式光电传感器，其中，托板位于反射式光电传感器的第一探测距离处，并且第一探测距离大于反射式光电传感器的最佳探测距离。

具体实施方式
以下结合附图对本发明的实施例进行详细说明，但是本发明可以由权利要求限定和覆盖的多种不同方式实施。
图2是根据本发明一实施例的纸币清分机的结构剖面图。如图2所示，纸币清分机设置有与外界连通的入币口S0、至少一个出币口，以及至少一个退币口，纸币清分机内部设置有主通道P、进币机构1、纸币鉴别机构2、输送机构、换向机构，以及介质将满检测机构。
其中，入币口S0位于主通道P的一端，用于堆叠待处理的纸币；进币机构1设置在入币口S0处，用于将堆叠在入币口S0处的纸币一张接一张地送进主通道P内。
纸币鉴别机构2设置在主通道P上，用于鉴别纸币的真伪及面额。纸币鉴别机构2包括图像检测机构21和磁检测机构22，其中，图像检测机构21包括两个相对设置 的图像传感器，用于获取纸币正反面的图像信息；磁检测机构22用来检测纸币上的安全线的磁信息，纸币清分机的控制器根据图像检测机构21和磁检测机构22的检测结果判断纸币的真伪、面额大小等信息。
出币口通过辅通道与主通道P连通，用于容纳经纸币鉴别机构2鉴别为正常的纸币；退币口用于容纳经纸币鉴别机构2鉴别为异常的纸币，如***、残币，当退币口的数量为一个时，退币口位于主通道P的另一端，当退币口的数量为多个时，退币口中的一个位于主通道P的另一端，其他的退币口通过辅通道与主通道P连通。
输送机构用于驱动纸币沿主通道P或辅通道运动。输送机构包括多个输送辊组3和多个叶轮4，其中，多个输送辊组3分别设置在主通道P和辅通道上，用于驱动纸币在各通道内运动；输送机构的叶轮4的数量与出币口和退币口的总数量相等，在每一个出币口和与其连通的辅通道之间设置有一个叶轮，用于将辅通道内的纸币逐张送至出币口内；在每一个退币口和与其连通的通道(即辅通道或主通道)之间设置有一个叶轮4，用于将通道内的纸币逐张送入退币口内。
本实施例中，纸币清分机包括入币口S0、两个出币口(即第一出币口S1和第二出币口S2)，以及一个退币口S3，输送机构包括三个叶轮4，辅通道包括第一辅通道P1和第二辅通道P2，其中，第一出币口S1通过第一辅通道P1与主通道P连通，用于容纳经纸币鉴别机构2鉴别为正常的第一种纸币，如壹佰元面额的人民币；沿纸币由入币口S0进入主通道P内向退币口S3运动的方向，第二出币口S2位于第一出币口S1的下游，第二出币口S2通过第二辅通道P2与主通道P连通，用于容纳经纸币鉴别机构2鉴别为正常的第二种纸币，如伍拾元面额的人民币；输送机构的多个输送辊组3分别设置在主通道P、第一辅通道P1、第二辅通道P2上，用于驱动纸币在各通道内运动；三个叶轮4分别设置在第一辅通道P1与第一出币口S1之间、第二辅通道P2与第二出币口S2之间，以及主通道P与退币口S3之间。
换向机构包括第一换向件51、第二换向件52，以及第一驱动件和第二驱动件(图中未示出)。其中，第一换向件51设置在主通道P与第一辅通道P1的交汇处，与纸币清分机的机架(图中未示出)活动连接；第二换向件52设置在主通道P与第二辅通道P2的交汇处，与机架活动连接；第一驱动件和第二驱动件可以是凸轮或者电磁铁等，其中，第一驱动件与第一换向件51连接，在第一驱动件的驱动下，第一换向件51具有第一位置和第二位置。当第一换向件51位于第一位置时，主通道P与第一辅通道P1连通，位于主通道P内的纸币通过第一换向件51的引导被送至第一辅通道P1内；当第一驱动件驱动第一换向件51运动到第二位置时，主通道P与第一辅通道P1之间的通路被断开，纸币只能沿主通道P继续向下游移动；第二驱动件与第二换向件52 连接，在第二驱动件的驱动下，第二换向件52具有第一位置和第二位置，其中，当第二换向件52位于第一位置时，主通道P与第二辅通道P2连通，位于主通道P内的纸币通过第二换向件52的引导被送至第二辅通道P2内；当第二驱动件驱动第二换向件52运动至第二位置时，主通道P与第二辅通道P2之间的通路被断开，主通道P与退币口S3连通，主通道P内的纸币被送至退币口S3内。
介质将满检测机构设置在退币口S3处，用于检测退币口S3处容纳的纸币是否将要堆满。图3是根据本发明一实施例的纸币清分机的退币口的结构示意图，图4是根据本发明一实施例的纸币清分机的退币口内堆叠有纸币时的示意图。如图3、图4所示，退币口S3包括托板81、顶壁82、左侧壁83，右侧壁84，以及挡板85，其中，顶壁82与托板81相对间隔设定距离，两者之间形成了纸币堆叠空间，纸币堆叠在托板81上，随着堆叠的纸币增多，堆叠纸币中的最上一张纸币与顶壁82之间的距离逐渐缩小，在托板81的下沿的中部设有用于取币的凹口812；左侧壁83和右侧壁84分别位于托板81和顶壁82的左右两侧，两者之间的距离大于等于纸币的最大长度；挡板85位于托板81的远离主通道P的一端，并与托板81呈夹角设置，用于阻挡堆叠在托板81上的纸币掉出退币口S3。
介质将满检测机构为反射式光电传感器6，其固定安装在退币口S3的顶壁82上，反射式光电传感器6穿过顶壁82上的缺口821与托板81的上表面相对。反射式光电传感器6包括光发生器61和光接收器62，当托板81上没有纸币时，光发生器61发出的光线照射在托板81上，经托板81反射的部分反射光被光接收器62接收，当托板81上堆叠有纸币时，反射式光电传感器6与纸币相对，光发生器61发出的光线照射在纸币上，纸币反射的部分反射光被光接收器62接收，光接收器62接收到反射光后经过光电转换输出光电流。
图5是根据本发明一实施例的纸币清分机的介质将满检测机构的探测距离特性曲线图。下面结合图5，说明本发明提供的介质将满检测机构的工作原理。如图5所示，d为反射式光电传感器6的探测距离，即反射式光电传感器6与纸币或托板81的上表面之间的距离，I为反射式光电传感器6输出的光电流，反射式光电传感器6输出的光电流I与检测的探测距离d相关，当托板81上没有纸币时，反射式光电传感器6与托板81上表面之间的距离为探测距离，此时探测距离最大，经托板81反射回光接收器62的光线强度最弱，因此反射式光电传感器6输出的光电流较小；随着托板81上的纸币数量逐渐增加，反射式光电传感器6的探测距离逐渐减小，反射式光电传感器6的光接收器62接收到的反射光线强度逐渐增加，因此，反射式光电传感器6输出的光电流逐渐增大；当托板81上堆叠的纸币中的最上一张与反射式光电传感器6之间的探 测距离为传感器的最佳探测距离D0时，反射式光电传感器6输出最大光电流Imax；如果继续向退币口S3内输送纸币，则退币口S3内堆叠的纸币中的最上一张纸币与反射式光电传感器6之间的距离d逐渐减小，光发生器61发出的光线折射角增大，导致反射式光电传感器6的光接收器62接收到的反射光线的数量开始减少，因此，反射式光电传感器6输出的光电流逐渐减小。
因此，通过预设阈值，当反射式光电传感器6输出的光电流大于预设阈值时，纸币清分机的控制器即可判断退币口S3内堆叠的纸币将满，发出提示信息。例如，如图5中所示，在传感器的最佳探测距离D0的基础上加减δ，然后取D0+δ和D0-δ两个探测距离对应的光电流中的较小值a作为预设阈值，当反射式光电传感器6输出的光电流大于a时，此时托板81上堆叠在纸币的最上一张与反射式光电传感器6之间的距离在D0-δ～D0+δ之间，控制器判断退币口S3内堆叠的纸币将满，控制纸币清分机的提示装置发出提示信息。
本发明提供的纸币清分机的退币口处设置有退币口将满检测装置，退币口将满检测装置包括反射式光电传感器，其中，退币口包括相对设置的托板和顶壁，退出的纸币堆叠在托板上，且位于托板与顶壁之间，反射式光电传感器设置在顶壁上且与托板相对，当反射式光电传感器输出的光电流满足预设阈值要求时，纸币清分机的控制器判断退币口内容纳的纸币将满，以据此控制纸币清分机的提示装置发出提示信息，提醒操作者及时清理退币口。因此与现有技术中的纸币清分机相比，本发明提供的纸币清分机设有用于检测退币口的纸币是否将要堆满的介质将满检测机构，从而能够及时提醒操作者清理退币口，避免了退币口堵塞造成的设备故障问题。
图6是根据本发明另一实施例的纸币清分机的局部结构示意图。如图6所示，本实施例中，在托板81上正对反射式光电传感器6的位置设有使反射式光电传感器6形成光路断路的结构，该结构可以是豁口811。当退币口S3的托板81上没有纸币时，反射式光电传感器6的光发生器61发出的光线经过豁口811后无法被反射至光接收器62，因此，此时反射式光电传感器6输出第一信号，当退币口S3的托板81上有纸币时，反射式光电传感器6的光发生器61发出的光线被纸币反射至光接收器62，反射式光电传感器6输出第二信号。本实施例中，通过在托板上设置豁口，使反射式光电传感器6还能够检测退币口是否存在纸币。
图7是根据本发明又一实施例的纸币清分机的局部结构示意图。如图7所示，本实施例中，在托板81上正对反射式光电传感器6的位置设有使反射式光电传感器6形成光路断路的光路元件813，如反光件、折光件或透光件,反射式光电传感器6的光发生器61发出的光线被光路元件813反射到光接收器62的接收范围之外，从而无法 被反射至光接收器62，因此，此时反射式光电传感器6输出第一信号，当退币口S3的托板81上有纸币时，反射式光电传感器6的光发生器61发出的光线被纸币反射至光接收器62，反射式光电传感器6输出第二信号。本实施例中，通过在托板上设置光路元件，使反射式光电传感器6还能够检测退币口是否存在纸币。
本发明提出了用于解决检测退币口是否存在纸币和退币口中纸币是否将满问题的技术方案，本领域技术人员可以理解，该技术方案也可以用于打印机、扫描仪等薄片类介质处理装置的薄片类介质的堆叠存放部例如存储室/仓中，用于解决类似的问题，即用于检测堆叠存放部中是否存在介质，以及所存放的介质是否将满。在一实施例中，堆叠存放部的顶壁(例如由顶板或类似件形成)上设置反射式光电传感器，堆叠存放部的托板(例如由底板或类似物形成)位于反射式光电传感器的第一探测距离处，用于堆叠薄片类介质，该第一探测距离大于反射式光电传感器的最佳探测距离。当反射式光电传感器输出值满足预设阈值要求时，薄片类介质处理装置的控制器判断堆叠存放部中堆叠的薄片类介质将满，以据此控制薄片类介质处理装置的提示装置发出提示信息，提醒操作者及时清理堆叠存放部。
进一步地，托板上正对反射式光电传感器的位置设有使反射式光电传感器形成光路断路的光路元件或结构，该结构较简单的形式为豁口，该光路元件可以是反光件、折光件或透光件等元件。当堆叠存放部中没有薄片类介质时，反射式光电传感器的光路因光路元件或结构发生断路，因此，此时反射式光电传感器输出第一信号，当堆叠存放部中有薄片类介质时，反射式光电传感器输出第二信号，薄片类介质处理装置的控制器据此判断介质堆叠存放部内是否存在薄片类介质。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
