Description

一种双面验钞机 技术领域
本发明涉及验钞技术领域，尤其涉及一种双面验钞机。
背景技术
传统的验钞机有多种验伪技术，最常见的有磁头、红外对管(红外发射器和红外接收器)、紫光传感器和荧光传感器，其中，纸钞的进钞方向(正面或反面)并不影响磁头和红外对管的检测结果，但会影响紫光传感器和荧光传感器，因为紫光灯和紫光传感器、荧光灯和荧光传感器是在纸钞的同一个方向，所以检测的要么是纸钞背面，或者纸钞正面，所以属于单面验钞，无法对纸钞双面进行检测鉴伪。
发明内容
本发明的目的在于提供一种双面验钞机，可以实现对纸钞的双面鉴伪。
本发明是这样实现的：一种双面验钞机，包括机架、捻钞组件、出钞组件、接钞组件、显示器、驱动组件、控制电路板和正面验钞电子组件，所述正面验钞电子组件与控制电路板电连接，所述出钞组件包括第一组压钞轮和第二组压钞轮，每组压钞轮包括上压钞轮和下压钞轮，二个上压钞轮通过上皮带连接，二个下压钞轮通过下皮带连接，纸钞被捻钞组件送入机架内部，通过第一组压钞轮后被上下皮带夹紧悬空运输，通过第二组压钞轮后送入接钞组件，所述验钞机还包括反面验钞电子组件，所述反面验钞电子组件与控制电路板电连接，所述反面验钞电子组件设置在第一组压钞轮和第二组压钞轮之间验钞通道的下方。
其中，所述上下皮带数量均为二条，位于出钞组件的左右两端，用于夹紧纸钞的两侧边缘。
其中，所述正面验钞电子组件包括多个磁头、多对红外感器、紫外灯、紫光传感器和荧光传感器。
其中，所述反面验钞电子组件包括紫外灯、紫光传感器和荧光传感器。
此处的正面和反面，并非指纸钞的正反面，因为进入验钞通道的纸钞可正可反，在本发明中正反是指验钞通道的上方为正面，对应纸钞的上表面，验钞通道的下方为反面，对应纸钞的下表面。
本发明的有益效果为：所述双面验钞机中的捻钞组件、接钞组件、驱动组件和正面验钞电子组件仍然采用传统的结构，并未做出改变，正面验钞电子组件大部分位于验钞通道的 上方(红外对管上下都有)，主要用于对纸钞上表面进行鉴伪，但对出钞组件进行了较大改进，还增加了反面验钞电子组件，所述出钞组件包括第一组压钞轮和第二组压钞轮，每组压钞轮包括上压钞轮和下压钞轮，二个上压钞轮通过上皮带连接，二个下压钞轮通过下皮带连接，纸钞被捻钞组件送入机架内部，通过第一组压钞轮后被上下皮带夹紧悬空运输，通过第二组压钞轮后送入接钞组件，第一组压钞轮为主动轮，第二组压钞轮为从动轮，之所以让纸钞在上下皮带夹紧悬空运输，是为了给反面验钞电子组件提供安装空间和检测空间；所述反面验钞电子组件设置在第一组压钞轮和第二组压钞轮之间验钞通道的下方，主要用于对纸钞下表面进行鉴伪。本发明所述双面验钞机可以实现双面验钞，对传统的验钞机改动很小，也不会大幅增加体积，具有明显优势。

具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
作为本发明所述双面验钞机实施例一，如图1和图2所示，包括机架2、捻钞组件1、出钞组件9、接钞组件、显示器、驱动组件、控制电路板和正面验钞电子组件101，所述正面验钞电子组件101与控制电路板电连接，所述出钞组件9包括第一组压钞轮91和第二组压钞轮92，每组压钞轮包括上压钞轮93和下压钞轮94，二个上压钞轮93通过上皮带95连接，二个下压钞轮94通过下皮带96连接，纸钞被捻钞组件1送入机架2内部，通过第一组压钞轮91后被上下皮带95、6夹紧悬空运输，通过第二组压钞轮92后送入接钞组件，所述验钞机还包括反面验钞电子组件102，所述反面验钞电子组件102与控制电路板电连接，所述反面验钞电子组件102设置在第一组压钞轮91和第二组压钞轮92之间验钞通道的下方。
在本实施例中，所述上下皮带95、96数量均为二条，位于出钞组件9的左右两端，用于夹紧纸钞的两侧边缘。
在本实施例中，所述正面验钞电子组件101包括多个磁头、多对红外感器、紫外灯、紫光传感器和荧光传感器，所述反面验钞电子组件102包括紫外灯、紫光传感器和荧光传感器。
所述双面验钞机中的捻钞组件1、接钞组件、驱动组件和正面验钞电子组件101仍然采用传统的结构，并未做出改变，正面验钞电子组件101大部分位于验钞通道的上方(红外对管上下都有)，主要用于对纸钞上表面进行鉴伪，但对出钞组件9进行了较大改进，还增加了反面验钞电子组件102，所述出钞组件9包括第一组压钞轮91和第二组压钞轮92，纸钞被捻钞组件1送入机架2内部，通过第一组压钞轮91后被上下皮带95、96夹紧悬空运输，第一组压钞轮91为主动轮，第二组压钞轮92为从动轮，之所以让纸钞在上下皮带95、96夹紧悬空运输，是为了给反面验钞电子组件102提供安装空间和检测空间；所述反面验钞电子组件102设置在第一组压钞轮91和第二组压钞轮92之间验钞通道的下方，主要用于对纸钞下表面进行鉴伪。本发明所述双面验钞机可以实现双面验钞，对传统的验钞机改动很小，也不会大幅增加体积，具有明显优势。
众所周知，钞票上的细菌种类多，数量大，对每张钞票进行消毒灭菌，是根绝病毒传播的重要措施，减少钞票流通使用过程中引起细菌病毒对人的交叉传染，逐张对钞票表面进行 快速消毒杀菌已成为一个迫切需要解决的世界课题。专利号为CN201520783267.2的中国实用新型专利就公开了一种带有消毒杀菌功能的点钞机，主要采用的技术为设置强力紫外线杀菌灯，以及对钞票进行喷洒消毒液，高效杀菌。但是在验钞过程中，钞票翻转，还是会有大量的细菌被卷扬起来，进入空气中，危害使用验钞机用户的身体健康，有待改进。
作为本发明所述双面验钞机实施例二，如图3至图8所示，包括机架2、捻钞组件、出钞组件、接钞组件、显示器、驱动组件和控制电路板，所述机架2顶部内侧设有紫外线杀菌灯(未示出)，所述验钞机的出钞口处设有密封罩5，所述密封罩5的上半部51用于覆盖整个出钞口，所述密封罩5的下半部52内设有抽风风扇6和空气过滤器7，密封罩的上半部51和下半部52通过通孔53连通，所述空气过滤器7设置在所述通孔53处，所述密封罩的下半部52设有出风孔54，所述抽风风扇6设置在所述出风孔54处，所述密封罩的上半部51还设有取钞活动门8，所述取钞活动门8包括滑板81和折页82，所述滑板81水平滑动地设置在密封罩5上部，所述滑板81尾部还设有复位弹簧83，所述滑板81与折页82通过枢轴84枢接，所述枢轴84上还设有用于折页82旋转复位的扭簧85。其中，钞票标号为100。
所述验钞机仍然采用紫外线杀菌灯进行杀菌，但并未采用喷洒消毒液进行消毒，因为喷洒装置体积较大，应用在常规的、便携式的验钞机中不太现实，另外为了解决验钞过程中，钞票翻转，污染空气的问题，在验钞机整体上未做大的变动情况下，特别在验钞机的出钞口处增设了密封罩5，所述密封罩的上半部51用于覆盖整个出钞口，保证整个验钞机处于半密闭状态(除了进钞口)，密封罩上半部51内被污染的空气从通孔53处进入密封罩的下半部52，被空气过滤器7净化，最后被抽风风扇6抽出验钞机，验钞机内形成了一个空气净化循环通道，所以不会污染周围的空气。设置了密封罩5后必然会影响取钞，所以在密封罩的上半部51还设置了取钞活动门8，所述取钞活动门8包括滑板81和折页82，滑板81可以在水平方向滑动，或者叫做伸缩，折页82相对滑板81可以翻转。当需要取钞时，用手下压折页82翻转，并推挤滑板81，使滑板81缩回，取钞活动门8完全打开后，取钞的空间足够大，使手和钞票自由进出，取完钞票后，滑板81在复位弹簧83的作用下复位，折页82在扭簧85的作用下复位，取钞活动门8完全复位，形成密闭效果，以备下一次验钞。对现有的验钞机改动很小，改造成本低，有利于推广。
之所以采用这么复杂的结构主要原因在于：1、如果只设置旋转的取钞门，那么取钞门较长，在向下旋转的过程中，会与钞票干涉，影响取钞；2、如果只设置伸缩的取钞门，那么需要二只手操作，一手推动取钞门，一手取钞，会很不方便。
在本实施例中，所述密封罩5为透明材料制成，方便用户观察验钞情况。
在本实施例中，所述密封罩5上部设有滑槽55，所述滑板81设置在所述滑槽55内。滑 板81可顺滑地在滑槽55内水平滑动。
在本实施例中，所述密封罩5上部固定设有导向柱56，所述复位弹簧83套设在所述导向柱56上，所述滑板81尾部设有导孔811，所述导孔811套设在导向柱56上。复位弹簧83不会脱落，移位，稳定性好。
在本实施例中，所述折页82上还设有角度限定块821，用于限定折页82与滑板81之间的最大打开角度。其实不设置角度限定块也是可行的，因为扭簧都有初始的稳定角度，在扭簧未受力时，折页能处于预设的密闭位置，那么就是可行的，因为扭簧可以支撑折页。
现有的验钞机的捻钞机构包括本体、设置于本体上的捻钞轴和设置于捻钞轴上的捻钞轮，钞票放入捻钞轮与本体之间，由捻钞轴带动捻钞轮转动，通过捻钞轮与钞票之间的摩擦力将钞票送入走币通道，但由于捻钞轮的外圆周表面全部为橡胶面，在该捻钞机构工作时，钞票即被捻钞轮连续地送入走币通道，易出现跟币、叠币等现象，故在捻钞轴后侧还设置有拖动钞票以将钞票带出走币通道的过钞轴，过钞轴上的送钞轮转动的线速度大于捻钞轮的线速度，使得叠币的钞票可被分开，但这易导致钞票被拉断，并且钞票之间连续的跟币较多，易出现后续的计数等错误。
为了解决这个问题，中国专利文献“200510094210.2点钞机的捻钞机构”公开了一种只有部分橡胶面的捻钞轮，捻钞时可以将钞票分开送走币通道内，这样就使得钞票间隔一段距离地进入走币通道，从而将前后进入走币通道的钞票分开，以便于拖币皮带将钞票平稳地带出，即可避免出现跟币、叠币现象，又可防止钞票被拉断。捻钞橡胶块安装在捻钞轮上，事实上在直径不足2cm的捻钞轮上设置安装捻钞橡胶块是较为困难的事情，捻钞橡胶块是软质材料，体积又小，固定困难，反复受压变形，容易脱落，而且捻钞橡胶块的工作表面面积较小，容易磨损，磨损之后，捻钞轮需要全部更换，成本较高，有待改进。
作为本发明所述双面验钞机的实施例三，如图9至图11所示，本实施例中所述捻钞组件1包括捻钞轴11、捻钞轮12、捻钞胶圈13和捻钞板14，所述捻钞轮12套设在捻钞轴11上，捻钞胶圈13套设在捻钞轮12上，所述捻钞胶圈13上设有一圈完整的防滑纹131，所述捻钞轮12与捻钞胶圈13相配合处的轴向截面为D形。
所述捻钞胶圈13具有弹性，把捻钞胶圈13套设到捻钞轮12上是比较容易的，由于所述捻钞轮12与捻钞胶圈13相配合处的轴向截面为D形，所以捻钞胶圈13在安装后整体也为D形，在捻钞工作过程中，捻钞胶圈13大约只有一半的表面能与钞票接触，可以达到间隔送钞的效果，避免出现跟币、叠币现象；又由于捻钞胶圈13上的防滑纹131设有一圈完整的防滑纹，所以把捻钞胶圈13套设到捻钞轮12上之后，不必对齐等操作，更方便。如果防滑纹131长时间使用磨损，那么可以手动旋转捻钞胶圈13使其它未磨损的表面处于工作 位置，就可以了，相比现有技术使用寿命得以延长两至三倍，完全磨损后，直接替换捻钞胶圈13就可以了，操作容易，维护成本较低。
在本实施例中，所述防滑纹131为棘齿型，摩擦力大，而且与钞票接触为超柔性接触，弹性空间大，可以接受的磨损量大，或者说磨损量较大之后，仍然能保证不错的工作效果，所以使用寿命长。
在本实施例中，所述捻钞轮12为金属轮或者POM塑料轮。
在本实施例中，所述捻钞轮12外圆周面设有一圈环形凹槽121，所述捻钞胶圈13嵌入所述环形凹槽121内，部分捻钞胶圈13的表面超出捻钞轮12的外圆周面，部分捻钞胶圈13的表面未超出捻钞轮12的外圆周面，所述捻钞胶圈13和环形凹槽121之间形成的摩擦力较大，捻钞轮12和捻钞胶圈13在工作过程中，位置稳定性高，不会移位。
作为所述捻钞组件的另一实施例，如图12所示，所述捻钞轮12外圆周面设有一圈环形凹槽121，所述捻钞胶圈13的内表面上设有环形凸起132，所述环形凸起132嵌入所述环形凹槽121内，所述环形凹槽121和环形凸起132之间形成的摩擦力较大，该结构也能增加捻钞轮12和捻钞胶圈13之间的摩擦力，有效防止两者相对移位。
作为本发明所述双面验钞机的实施例四，如图13至图14所示，与实施例三不同之处在于所述验钞机还包括压钞件4，所述机架2包括左入钞板21和右入钞板22，左右入钞板21、22均设有固定轴3，所述固定轴3设置在捻钞轴11旁边，所述压钞件4套设在固定轴3上，所述压钞件4与捻钞板14之间最近的距离为3-5mm。钞票被捻钞轮12带起从捻钞轮12和捻钞板14之间穿过，由于钞票具有较大的速度，而且钞票的折痕不规则，容易向上飞起，产生飞钞的情况。本实施例所述压钞件4可以压住从捻钞轮12送来钞票，平稳地离开捻钞轮12和捻钞板14，顺利地进入出钞组件，防止飞钞，使捻钞过程更加平稳。由于钞票的折痕不规则性，压钞件4不宜直接与捻钞板14接触，有机会卡钞，压钞件4与捻钞板14之间最近的距离设置为3-5mm，是比较合适的，保证钞票的通过率，又能保证较好的压钞效果，防止飞钞。
在本实施例中，所述压钞件4包括套环41和尾部压条42，所述套环41内表面设有凹槽411，所述固定轴3的外圆面上设有凸起31，所述凸起31位于凹槽411内，使套环41与固定轴3在3-5度的范围内自由旋转，所述尾部压条42的长度大于5cm。由于压钞件4可以绕固定轴在3-5度的范围内自由旋转，所以高速过来的钞票冲击压钞件4时，压钞件4的重力不足以压制钞票时，就会向上旋转，增加进钞空间，增加了结构的柔性，此时一般情况是钞票的折痕太大，钞票太不平整导致的，增加进钞空间以避免卡钞。但是压钞件4也不能向上旋转角度过大，否则容易与外部其它结构碰撞，产生噪音。另外，还可以在所述凸起31上 套设一硅胶套，防止凸起31和凹槽411之间接触磨损，以及降低接触噪音。在允许的范围下，钞票的引导距离越大越好，为了保证基本的钞票引导效果，所述尾部压条42的长度应大于5cm。
作为所述压钞件的另一实施例，如图15所示，所述压钞件4包括套环41和尾部压条42，套环41上设有缺口412，所述固定轴3的外圆面上设有凸起31，所述凸起31位于缺口412内，使套环41与固定轴3在3-5度的范围内自由旋转，所述尾部压条42的长度大于5cm。由于缺口412的存在，所述凸起31可以做的较粗较强壮，高度上也不再受限，可以设计得更高，解决产品的强度问题，降低维护率，提高用户满意度。可以在所述凸起31上套设一硅胶套，防止凸起31和缺口412之间接触磨损，以及降低接触噪音。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
