Description

踢纸机构、纸币处理机和薄片类介质处理装置
本申请要求2014年7月11日提交至中国知识产权局的、申请号为201420384354.6、名称为“踢纸机构、纸币处理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
本发明涉及一种踢纸机构，以及使用该踢纸机构的纸币处理机和薄片类介质处理装置。
背景技术
如图1所示，现有的纸币清分机、点钞机等纸币处理机为了实现多张纸币的批量处理，往往在入钞口处设置踢纸机构和分离机构2'，以及驱动机构，用于将放置在入钞口处的一摞纸币一张接一张地依次送入纸币处理机内部进行鉴别、清分等处理操作。
其中，踢纸机构包括踢纸辊1'，踢纸辊1'包括芯轴11'和固定套设在芯轴11'外周上的辊轮12'，当芯轴11'转动时，辊轮12'随之同步转动。辊轮12'包括沿其圆周分布的高摩擦部121'和基体部122'，其中，高摩擦部121'与纸币之间的摩擦力大于纸币与纸币之间的摩擦力，基体部122'与纸币之间的摩擦力小于纸币与纸币之间的摩擦力；沿纸币输送方向，分离机构2'位于踢纸机构的下游，分离机构2'包括相对间隔设置的分离辊21'和反转辊22'，两者之间的距离大于单张纸币的厚度、小于两张纸币的厚度；驱动机构包括第一电机M1和第二电机M2，其中，第一电机M1用于驱动踢纸辊1'以及分离辊21'沿进币方向转动，第二电机M2用于驱动反转辊22'沿退币方向转动。
当多张纸币堆叠在托板8'上时，第一电机M1驱动踢纸辊1'和分离辊2'沿进币方向转动，第二电机M2驱动反转辊22'沿退币方向转动，踢纸辊1'上的高摩擦部121'与纸币接触时，高摩擦部121'驱动与其接触的纸币进入分离辊21'与反转辊22'之间，如果此时踢纸辊121'送至分离辊21'与反转辊22'之间的纸币为多张时，分离辊21'驱动与其接触的纸币向其下游输送，反转辊22'驱动与其接触的纸币向其上游输送，即只有与分离辊21'接触的纸币被向下游输送，从而使一张接一张地依次送入纸币处理机内部。
上述踢纸机构每次完成纸币处理后，踢纸辊1'上的高摩擦部121'的停止位置不确定，这样在启动下一次纸币输送的开始时刻，容易产生空转，引起输送打滑。现有技术中尚未对提高踢纸机构可靠性提出有效的解决方案。

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。
现有技术的踢纸机构的踢纸辊在每次完成纸币处理后，踢纸辊上的高摩擦部的停止位置不确定，这样在启动下一次纸币输送的开始时刻，容易产生空转，引起输送打滑。同时，当批量处理纸币时，如果始终按恒定转矩驱动踢纸辊转动，则当处理的纸币较新时摩擦阻力较小，踢纸辊转动速度较快，当纸币较旧时摩擦阻力较大，踢纸辊转动速度较慢，前后两张纸币容易产生首尾相连引起纸币的卡塞。因此，现有技术中尚未对提高踢纸机构可靠性提出有效的解决方案。
本发明人发现，现有技术的踢纸机构存在纸币卡塞的原因在于：踢纸辊按恒转矩驱动，当处理的纸币较新时摩擦阻力较小，踢纸辊转动速度较快，当纸币较旧时摩擦阻力较大，踢纸辊转动速度较慢，前后两张纸币容易产生首尾相连引起纸币的卡塞。另外，上述踢纸机构每次完成纸币处理后，踢纸辊上的高摩擦部的停止位置不确定，这样在启动下一次纸币输送的开始时刻，容易产生空转，引起输送打滑，在认清上述问题的基础上，可以理解，对踢纸辊的转动速度进行调整和对高摩擦部的停止位置进行控制均有利于避免上述问题的发生，进而能够提高踢纸机构的可靠性。
图2a是根据本发明一实施例的踢纸机构的结构示意图，图2b是根据本发明一实施例的踢纸机构的结构主视图。如图2a、图2b所示，踢纸机构包括踢纸辊1和检测组件5，其中，踢纸辊1包括芯轴11和辊轮12，其中，芯轴11沿纸币宽度方向延伸，其两端由机架(图中未示出)支撑，在芯轴11的一端设置有带轮111，用于与使用该踢纸机构的纸币处理机的驱动组件传动连接，在驱动组件的驱动下，芯轴11可绕自身轴线沿设定方向(如图3中所示的逆时针方向)转动；辊轮12固定设置在芯轴11的外周，可以是一根长度与薄片类纸币最大宽度相适配的一体辊，也可以是沿芯轴11轴向间隔排布的分段辊，当芯轴11转动时，辊轮12随芯轴11同步转动。本实施例中，辊轮12包括沿芯轴11轴向排布的四个分段辊轮12a，四个分段辊轮12a两两一组左右对称排布。
其中，沿圆周方向，辊轮12包括基体121和高摩擦部122，其中，基体121与纸币之间的摩擦系数α1小于纸币与纸币之间的摩擦系数α0，即α1<α0；高摩擦部122与纸币之间的摩擦系数α2大于纸币与纸币之间的摩擦系数α0，即α2>α0>α1，优选的，高摩擦部122由橡胶材料组成；沿辊轮12圆周方向高摩擦部122的长度大于等于踢纸辊1驱动纸币移动的距离，沿踢纸辊1的转动方向，高摩擦部122具有起始位置A和终止位置B。
检测组件5用于检测踢纸辊1的转动速度，并检测踢纸辊1上的高摩擦部122是否转动至设定的停止位置上。检测组件5包括传感器51和检测盘52，其中，传感器51固定设置在机架上，传感器51为光电式传感器，包括相对间隔设置的光发射器511 和光接收器512；检测盘52与踢纸辊1的芯轴11固定连接，并插入光发射器511与光接收器512之间，当踢纸辊1转动时，检测盘52随之同步转动，并始终位于传感器51的光发射器511与光接收器512之间的光学通路上。
图3是根据本发明一实施例的踢纸机构的结构侧视图，图中为显示清楚，以黑块显示了传感器51的光学通路，而省略了传感器51的其他部分结构。如图3所示，检测盘52包括沿圆c的圆周均匀排布的位置检测口521和多个测速口522，以及实体部，其中圆c为以芯轴11的轴心为圆心的圆。本实施例中，实体部包括多个第一实体部523，一个测速口522和一个第一实体部523依次交替地排布在圆c上，位置检测口521位于两个第一实体部523之间。
当检测盘52转动时，位置检测口521、测速口522和第一实体部523均能从传感器51的光发射器511与光接收器512之间的光学通路经过。沿踢纸辊1的转动方向，位置检测口521与传感器51配合时的检测跨度L1不等于测速口522与传感器51配合时的检测跨度L2，也就是当踢纸辊1以恒定速度转动时，传感器51经过位置检测口521所需时间不等于经过测速口522所需时间。其中，沿踢纸辊1的转动方向，位置检测口521与传感器51配合时的终止位置b与踢纸辊1的辊轮12上的高摩擦部122的起始位置A间隔设定角度，当踢纸辊1的高摩擦部122停止在设定的停止位置上时，邻近位置检测口521的终止位置b的第一实体部523位于光发射器511和光接收器512之间的光学通路上。
本实施例中，沿踢纸辊1的转动方向，位置检测口521与传感器51配合时的检测跨度L1大于测速口522与传感器51配合时的检测跨度L2，也就是当踢纸辊1以恒定速度转动时，传感器51经过位置检测口521所需时间大于经过测速口522所需时间，其中，位置检测口521和测速口522均呈扇形环段，第一实体部523与传感器51配合时的检测跨度L3等于测速口522与传感器51配合时的检测跨度L2。
检测盘52随踢纸辊1同步转动。当检测盘52上的第一实体部523位于传感器51的光发射器511与光接收器512之间的光学通路中时，第一实体部523阻断光发射器511和光接收器512之间的光学通路，传感器51的光接收器512不能接收到光发射器511发出的光线，传感器51输出第一检测信号，如低电平；当检测盘52上的位置检测口521或测速口522位于传感器51的光发射器511与光接收器512之间的光学通路中时，传感器51的光接收器512能接收到光发射器511发出的光线，传感器51输出第二检测信号，如高电平。由于当踢纸辊1以恒定速度转动时，传感器51经过位置检测口521所需时间大于经过测速口522所需时间，因此，在踢纸辊1以恒定速度转动， 位置检测口521与传感器51配合使传感器51输出第二检测信号的时间t1远大于测速口522与传感器51配合使传感器51输出第二检测信号的时间t2。
图4是根据本发明一实施例的踢纸机构的检测组件的输出信号示意图。下面结合图4介绍本发明提供的踢纸机构的工作过程。
初始状态时，踢纸辊1的高摩擦部122位于设定的停止位置上，邻近位置检测口521的终止位置b的第一实体部523位于光发射器511和光接收器512之间的光学通路上，传感器51输出第一检测信号；当踢纸辊1开始沿设定方向(如图3中的逆时针方向)转动时，检测盘52随之同步转动，检测盘52上的第一实体部523、测速口522交替经过传感器51的光学通路，传感器51交替输出第一检测信号和第二检测信号，由于第一实体部523和测速口522与传感器51配合时的检测跨度相等，因此，传感器51输出第一检测信号的时间和输出第二检测信号的时间相等，均为t2，控制器可根据该时间t2与第一实体部523和测速口522与传感器51配合时的检测跨度L2计算得出检测盘52的转动速度，即踢纸辊1的转动速度，当踢纸辊1的转动速度不等于设定的转动速度时，可以通过调整纸币处理机的驱动组件输出的驱动转矩，使踢纸辊的转动速度等于设定的转动速度。
随着踢纸辊1继续转动，位置检测口521经过传感器51的光发射器511和光接收器512之间的光学通路，由于位置检测口521与传感器51配合时的检测跨度L1远大于测速口522与传感器51配合时的检测跨度L2，因此传感器51与位置检测口521配合输出第二检测信号的时间t1远大于传感器51与测速口522配合输出第二检测信号的时间t2。当需要踢纸辊1停止转动时，控制器检测传感器51输出的信号，当传感器51输出持续时间为t2的第二检测信号后又输出第一检测信号时，控制踢纸辊1停止转动，此时，邻近位置检测口521的终止位置b的第一实体部523位于光发射器511和光接收器512之间的光学通路上，踢纸辊1上的高摩擦部122恰好停止在设定的停止位置上。
本发明提供的踢纸机构包括踢纸辊和检测组件，其中，检测组件包括与踢纸辊同步转动的检测盘以及与检测盘配合的传感器，其中，检测盘上沿以踢纸辊的芯轴为圆心呈圆周均匀排布的位置检测口和多个测速口，以及位于多个测速口之间、测速口与位置检测口之间的实体部，其中，沿检测盘的转动方向，位置检测口与传感器配合的终止位置与踢纸辊上的高摩擦部所处的位置相关联，以控制踢纸辊的转动停止位置，且当踢纸辊以恒定速度转动时，传感器经过位置检测口所需时间大于经过测速口所需时间。当踢纸辊转动时，检测盘与传感器配合，传感器输出信号按照设定规律变化，根据传感器输出信号变化情况可以计算得出踢纸辊的转动速度，然后可以根据计算得 出的转动转矩调整纸币处理机的驱动组件输出的驱动转矩，使踢纸辊的转动速度等于设定的转动速度，还可以根据传感器输出信号变化情况控制踢纸辊停止在设定的停止位置上。因此，与现有技术中的踢纸机构相比，本发明提供的踢纸机构既可以检测踢纸辊的转动速度，还可以检测踢纸辊的位置，从而通过调整踢纸辊的转动速度和控制踢纸辊的停止位置避免了输送不可靠的问题，提高了踢纸机构的可靠性。
图5是根据本发明第二实施例的踢纸机构的结构侧视图，其中，踢纸辊停止在设定的停止位置上。如图5所示，本实施例中，实体部还包括两个第二实体部523'，两个第二实体部523'位于位置检测口521两侧，位置检测口521与测速口522之间，第二实体部523'与传感器51配合时的检测跨度L4不等于多个测速口522之间的第一实体部523与传感器51配合时的检测跨度L3对应的圆心角，本实施例中第二实体部523'与传感器51配合时的检测跨度L4大于第一实体部523与传感器51配合时的检测跨度L3，当踢纸辊1转动时，第二实体部523'与传感器51配合输出第一检测信号的时间t3大于第一实体部523与传感器51配合输出第一检测信号的时间t2。
图6是根据本发明第二实施例的踢纸机构的检测组件的输出信号示意图。如图6所示，初始状态时，踢纸辊1的高摩擦部122停止在设定位置上，邻近位置检测口521的终止位置b的第二实体部523'位于光发射器511和光接收器512之间的光学通路上，传感器51输出第一检测信号；当踢纸辊1开始转动时，检测盘52随之同步转动，检测盘52上的第二实体部523'经过光发射器511和光接收器512之间的光学通路，传感器51输出持续时间为t3的第一检测信号，当测速口522、第一实体部523交替经过传感器51的光发射器511和光接收器512之间的光学通路，传感器51交替输出持续时间为t2的第一检测信号和第二检测信号，控制器可根据该时间t2以及第一实体部523和测速口522与传感器51配合时的检测跨度L2、L3可以计算得出检测盘52的转动速度，即踢纸辊1的转动速度，随着踢纸辊1继续转动，邻近位置检测口521的初始沿a的第二实体部523'经过传感器51的光发射器511和光接收器512之间的光学通路，传感器51输出持续时间为t3的第一检测信号后输出持续时间为t2的第二检测信号，当需要踢纸辊1停止转动时，控制器检测传感器51输出的信号，当传感器51输出持续时间为t3的第一检测信号时，控制踢纸辊1降低转动速度，当传感器51输出持续时间为t2的第二检测信号变为输出第一检测信号时，控制踢纸辊1停止转动，此时，由于踢纸辊1的转动速度已经减小，因此避免了踢纸辊1从高速运动直接停止造成的过冲问题，保证了踢纸辊1停止位置准确。
图7是根据本发明第三实施例的踢纸机构的结构侧视图。如图7所示，本实施例中，位置检测口521'和各测速口522'均呈圆形，其中位置检测口521'为大圆孔，测速 口522'为小圆孔，沿踢纸辊1的转动方向，位置检测口521'与传感器51配合时的检测跨度大于测速口522与传感器51配合时的检测跨度。
图8是使用本发明提供的踢纸机构的纸币处理机一实施例的结构剖面图。本实施例中，纸币处理机为纸币清分机。如图8所示，纸币清分机设置有与外界连通的入币口S0、至少一个出钞口，以及退币口S3，纸币清分机包括主通道P、至少一个辅通道、踢纸机构100、分离机构200、纸币鉴别机构300、输送机构、换向机构，以及驱动机构(图中未示出)。
其中，入币口S0位于主通道P的起始位置，入币口S0处设置有托板8，用于堆叠待处理的纸币；踢纸机构100和分离机构200均设置在入币口S0处，其中踢纸机构100用于将堆叠在入币口S0处的纸币一张接一张地送至分离机构200，踢纸机构100可以采用上述任意一种踢纸机构，其结构形式、工作原理参见上述实施例描述，此处不再赘述。其中，踢纸机构100的踢纸辊1的辊轮12通过托板8上的开口(图中未示出)凸出于托板8上表面，可与堆叠在托板8上的纸币接触；踢纸辊1上的高摩擦部122沿踢纸辊1转动方向的长度大于等于踢纸辊1与分离机构200之间的距离；固定设置在踢纸辊1的芯轴11轴端的带轮111与驱动机构传动连接，在驱动机构的驱动下，踢纸辊1可沿进币方向转动。当踢纸辊1停止在设定的停止位置上时，沿进币方向，踢纸辊1上的高摩擦部122的起始位置a与托板8之间间隔设定距离，此时，邻近位置检测口521的终止位置b的第一实体部523位于传感器51的光发射器511和光接收器512之间的光学通路上，传感器51输出第一检测信号。
分离机构200用于将踢纸机构100送来的纸币分离，以将单张纸币送进主通道P内。分离机构200包括相对间隔设置的分离辊210和反转辊220，两者之间的距离大于单张纸币的厚度、小于两张纸币的厚度，其中，分离辊210与驱动机构传动连接，在驱动机构的驱动下可沿进币方向转动；反转辊220与驱动机构传动连接，在驱动机构的驱动下可沿退币方向转动。
纸币鉴别机构300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300包括图像检测机构310和磁检测机构320，其中，图像检测机构310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320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310和磁检测机构320的检测结果判断纸币的真伪、面额大小等信息。
出钞口通过辅通道与主通道P连通，用于容纳经纸币鉴别机构300鉴别为正常的纸币；退币口S3位于主通道P的末端，用于容纳经纸币鉴别机构300鉴别为异常的 纸币，如假币、残币；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401和多个叶轮402，其中，多个输送辊组401设置在主通道P或辅通道上，用于驱动纸币在主通道P或辅通道内运动；输送机构的叶轮402的数量与出钞口和退币口S3的总数量相等，其中，在每一个出钞口与辅通道之间设置有一个叶轮402，用于辅通道内的纸币逐张送入出钞口内，在退币口S3与主通道P之间设置有一个叶轮402，用于将主通道P内的纸币送至退币口S3内。
本实施例中，纸币清分机包括入币口S0、两个出钞口(即第一出钞口S1和第二出钞口S2)，两个辅通道(即第一辅通道P1和第二辅通道P2)以及退币口S3，输送机构包括三个叶轮402，其中，第一出钞口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300鉴别为正常的第一种纸币，如壹佰元面额的人民币；第二出钞口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300鉴别为正常的第二种纸币，如伍拾元面额的人民币；输送机构的三个叶轮402分别设置在第一辅通道P1与第一出钞口S1之间、第二辅通道P2与第二出钞口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510、第二换向件520，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510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520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510连接，在第一驱动件的驱动下，第一换向件510具有第一位置和第二位置。当第一换向件510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510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510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520连接，在第二驱动件的驱动下，第二换向件520具有第一位置和第二位置，其中，当第二换向件520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520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520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。
下面介绍本发明提供的纸币处理机的踢纸机构的工作过程。
待机状态时，踢纸机构100的踢纸辊1上的高摩擦部122位于设定的停止位置上，邻近位置检测口521的终止位置b的第一实体部523位于传感器51的光发射器511和光接收器512之间的光学通路上，传感器51输出第一检测信号。当一摞纸币堆叠在 托板8上时，踢纸辊1的辊轮12与一摞纸币中的最下一张纸币接触，纸币处理机的控制器控制驱动机构驱动踢纸辊1和分离辊210沿进币方向转动，驱动反转辊220沿退币方向转动，在踢纸辊1转动过程中，检测盘52随之同步转动，控制器根据传感器51输出的检测信号计算得出踢纸辊1的转动速度，当踢纸辊1的转动速度不等于设定速度时，控制器控制驱动机构调整驱动转矩，使踢纸辊1的转动速度等于设定转速，从而保证纸币被一张接一张地有序地送至分离机构200，当将托板8上的所有纸币均送出后，控制器检测传感器51的输出信号，当传感器51输出持续时间为t2的第二检测信号后又输出第一检测信号时，控制踢纸辊1停止转动，此时，邻近位置检测口521的终止位置b的第一实体部523位于光发射器511和光接收器512之间的光学通路上，踢纸辊1上的高摩擦部122恰好停止在设定的停止位置上。
纸币处理机使用了本发明提供的踢纸机构，能够随时检测踢纸辊的速度，并根据检测结果随时调整踢纸辊的转速，从而保证纸币一张接一张地被送出，当完成纸币输送后，还能够根据传感器输出的检测信号将踢纸辊停止在设定的停止位置上，保证每一次踢纸辊启动时均能够从同一位置启动，提高了产品的可靠性。
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。
