本发明涉及一种用于计量厚度的装置，特别是一种用于金融自助设备 中检测薄片类有价文件厚度的便于清除卡堵的厚度检测装置。 背景技术  BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a device for metering thickness, and more particularly to a thickness detecting device for detecting the thickness of a sheet-like document in a financial self-service device for facilitating the removal of a jam. Background technique
在金融自助设备中为了对批量处理的每一张薄片类有价文件（比如纸 币）逐一进行检验，需要将堆叠的薄片类有价文件一张张分离开来，然后 对分离的单张薄片类有价文件进行图像识别、 厚度检测、 磁信息检测等识 别手段，以保证所处理的薄片类有价文件的真实性，其中厚度检测在整个 检测中是必不可少的，厚度检测信息既可以用来判断所处理的薄片类有价 文件的真伪，还可以判断机械分离薄片类有价文件是否是一张，即是否是 重钞，以保证计数的准确性。  In the financial self-service device, in order to inspect each of the sheet-type value documents (such as banknotes) processed in batches one by one, it is necessary to separate the stacked sheet-type value documents one by one, and then separate the separated sheets. The value document carries out identification methods such as image recognition, thickness detection, and magnetic information detection to ensure the authenticity of the processed value documents. The thickness detection is indispensable in the whole inspection, and the thickness detection information can be used. To judge the authenticity of the processed value documents of the sheet, it is also possible to determine whether the mechanically separated sheet-like value document is a sheet, that is, whether it is a heavy bill to ensure the accuracy of counting.
目前针对薄片类有价文件的厚度检测有众多的方法，通常需要一个基 准辊和一个检测惰轮，并依靠被检测介质的挤压使得检测惰轮与基准辊之 间的距离发生改变，从而通过检测检测惰轮的位移间接获得被检测介质的 厚度值。 目前获得检测惰轮位移的手段有机械放大检测、 光电或磁信息放 大的方式来获得，而这些手段往往需要与检测惰轮组成一个较为占用空间 的部件，从而使得检测惰轮与基准辊之间的间隙被严密遮挡，如图 1所示。 该厚度检测装置，其包括一固定架 1 ,在所述固定架 1 内平行地对置的基 准辊 2 ,与基准辊对置的检测机构 3 ,以及固定在固定架 1 中形成引导介 质通过的导向板（4、 5 ) , 由于检测惰轮机构中惰轮是若干个，之间存在 一定间隔， 因此在介质被高速送入时可能出现折角卡堵现象， 当介质在此 处出现卡堵时，由于导向板 4和 5的存在，基本没有任何工具可以轻易到 达基准辊和检测惰轮之间的位置，除非，对该厚度检测装置进行彻底拆卸， 但是对装置的整体拆卸会造成基准辊与检测惰轮之间的重新定位等技术问 题。 当基准辊与检测惰轮之间的标定间隙发生改变之后需要对整个厚度检 测进行重新校正和标定，为设备的维护带来极大的不方便。 At present, there are numerous methods for thickness detection of sheet-like documents, usually requiring a reference roller and a detecting idler, and relying on the pressing of the detected medium to change the distance between the detecting idler and the reference roller, thereby passing The detection of the displacement of the idler wheel indirectly obtains the thickness value of the medium to be inspected. At present, the means for detecting the displacement of the idler wheel is obtained by means of mechanical amplification detection, photoelectric or magnetic information amplification, and these means often need to form a space with the detection idler. The components are such that the gap between the detecting idler and the reference roller is tightly shielded, as shown in FIG. The thickness detecting device includes a fixing frame 1 , a reference roller 2 opposed to each other in the fixing frame 1 , a detecting mechanism 3 opposed to the reference roller, and a fixing medium 1 fixed in the fixing frame 1 to form a guiding medium. The guide plates (4, 5), because there are several idlers in the detecting idler mechanism, there is a certain interval between them, so the folding phenomenon may occur when the medium is fed at a high speed, when the medium is jammed here. Due to the presence of the guide plates 4 and 5, substantially no tool can easily reach the position between the reference roller and the detection idler unless the thickness detecting device is completely disassembled, but the overall disassembly of the device causes the reference roller to Technical problems such as repositioning between idlers are detected. When the calibration gap between the reference roller and the detecting idler is changed, the entire thickness detection needs to be recalibrated and calibrated, which brings great inconvenience to the maintenance of the equipment.
因此急需对该技术问题进行改进设计。 发明内容  Therefore, there is an urgent need to improve the design of this technical problem. Summary of the invention

结合图 2、 图 5至图 9 ,详细说明该厚度检测装置的主要组成部件以 及其位置关系，本实施例中是对薄片类介质进行全幅面厚度检测的便于清 除卡堵的厚度检测装置，其中检测惰轮机构 03为 12个，沿垂直于薄片类 介质的传输方向并列布放。 当然根据设计需要，可以对检测惰轮机构 03 进行增减，理论上，在宽度一定的范围内设置的惰轮机构 03越多，对通 过的薄片类介质的厚度检测越精细，金融设备对通过介质的鉴别判断越准 确。  2, FIG. 5 to FIG. 9, the main components of the thickness detecting device and the positional relationship thereof are described in detail. In this embodiment, the thickness detecting device for detecting the full-width thickness of the sheet-like medium is convenient for clearing the jam. The number of detecting idler mechanisms 03 is 12, which are arranged side by side in the direction perpendicular to the transport direction of the sheet-like medium. Of course, according to the design requirements, the detection idler mechanism 03 can be increased or decreased. In theory, the more the idler mechanism 03 is set in a certain width range, the finer the thickness detection of the passing sheet medium, and the financial equipment pair passes. The more accurate the discrimination of the medium is.
结合图 6所示，所述检测惰轮机构 03中的支架 031上通过轴承安装 的惰轮 033为两个，在支架 031上还设有一刮尘片 035 ,该刮尘片 035刮 抵惰轮 033的表面，在其转动过程中刮除表面的积尘。  As shown in FIG. 6, the bracket 031 in the detecting idler mechanism 03 has two idler pulleys 033 mounted on the bearing, and a scraping piece 035 is further disposed on the bracket 031, and the scraping blade 035 is scraped against the idler pulley. The surface of 033 scrapes off the surface dust during its rotation.
结合图 7、 8和 9所示，为了保证检测惰轮机构 03中的磁性元件 034 与弹性封装板 04上透磁孔 041的相对位置稳定，在弹性封装板 04的透磁 孔 041设有夹持所述检测惰轮机构 03的弹片 042 ,所述弹片 042为一对 由透磁孔向检测惰轮机构延伸的弹性臂。 结合图 10所示，厚度检测装置正常使用时，被检测薄片类介质 Ρ被 高速送入导向板 06和 07之间 ， 由于介质 Ρ的挤压作用 ，在基准辊 021 不动的情况下，检测惰轮机构 03当被检测的薄片类介质 Ρ挤压，发生背 向基准辊 021的移位，当检测惰轮机构 03发生移位后，检测惰轮机构 03 上的磁性元件 034与磁感应器 05之间的距离发生变化，从而通过数据处 理单元对磁感应器 05获得的磁通量变化来得出检测惰轮机构与基准辊之 间的相对位移值，从而间接获得被检测薄片类介质的厚度值。 由于被检测 的薄片类介质被高速送入，再加上检测惰轮为多组，每组之间存在一定的 间隙，而这些间隙的存在会导致高速通过的薄片类介质由于折角等原因在 基准辊 021和基板 012处出现卡堵，当出现清除时可以将导向后板 07绕 轴 071转动而打开，如图 1 1所示，方便对发生卡堵的介质进行彻底清除， 而避免了对检测装置的拆卸。 As shown in FIGS. 7, 8, and 9, in order to ensure that the relative position of the magnetic member 034 in the detecting idler mechanism 03 and the magnetically permeable hole 041 on the elastic package board 04 is stabilized, the magnetic flux hole 041 of the elastic packaging board 04 is provided with a clip. The elastic piece 042 of the detecting idle gear mechanism 03 is a pair of elastic arms extending from the magnetic flux hole to the detecting idle gear mechanism. As shown in Fig. 10, when the thickness detecting device is normally used, the detected sheet-like medium is fed between the guide plates 06 and 07 at a high speed, and is detected by the pressing action of the medium 在 when the reference roller 021 is not moving. The idler mechanism 03 is squeezed by the detected sheet-like medium, and a displacement toward the reference roller 021 occurs. When the detecting idler mechanism 03 is displaced, the magnetic member 034 and the magnetic sensor 05 on the idler mechanism 03 are detected. The distance between them changes so that the relative displacement value between the detecting idler mechanism and the reference roller is obtained by the magnetic flux change obtained by the data processing unit with respect to the magnetic sensor 05, thereby indirectly obtaining the thickness value of the detected sheet-like medium. Since the detected sheet-like medium is fed at a high speed, and the detecting idler is a plurality of groups, there is a certain gap between each group, and the existence of these gaps causes the high-speed passing sheet-like medium to be in the reference due to the folding angle or the like. A jam occurs at the roller 021 and the substrate 012. When the cleaning occurs, the guiding rear plate 07 can be rotated around the shaft 071 to open, as shown in Fig. 11. It is convenient to completely remove the jammed medium, and avoid the detection. Disassembly of the device.
