Description

薄片类介质纠偏机构及薄片类介质处理装置 本申请要求 2012 年 10 月 25 日提交至中国知识产权局的、 申请号为 201210413349.9、 名称为 "薄片类介质纠偏机构及薄片类介质处理装置"的中国发明专 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 本发明涉及一种薄片类介质纠偏机构及薄片类介质处理装置。 背景技术 现有的薄片类介质的输送机构, 如打印机、 扫描仪、 识币器等薄片类介质处理设 备的薄片类介质输送机构, 通常包括至少一对相对设置的辊轮, 薄片类介质从相对设 置的辊轮之间穿过, 辊轮转动驱动薄片类介质运动。 为了适应尽可能多的薄片类介质类型, 往往要求输送通道的宽度与薄片类介质的 最大宽度相适配, 因此, 在进行较小宽度的薄片类介质输送时, 薄片类介质可能出现 偏斜现象, 在进行打印、 扫描等处理操作时, 将会造成打印内容偏斜、 扫描图像偏斜 等问题, 薄片类介质偏斜严重时还可能堵塞输送通道, 引起设备故障, 给用户带来不 便。 为了解决上述问题,中国专利 200510121474.2提供了一种解决方案,如图 1所示, 纠偏机构包括固定轴 1'、 固定板 2'、 纠偏装置 3'以及导板 4', 通过导板 4'将纠偏装置 3'固定在输送通道上, 其中纠偏装置 3'包括纠偏轮 30'和动力源 32', 纠偏轮 30'与动力 源 32'固定连接, 纠偏轮 30'与基准面 B呈夹角设置。 当纸张沿箭头 C方向进入输送通 道经过纠偏装置 3'时, 在动力源 32'的驱动下, 纠偏轮 30'始终推动纸张向基准面 B的 方向移动直至纸张沿基准面对齐, 从而实现了纸张的纠偏功能。 这种纠偏机构的问题在于, 当薄片类介质的一侧接触到基准面 B时, 由于还没有 完全对齐, 纠偏轮 30' 继续驱动薄片类介质向基准面 B方向移动, 有可能使薄片类介 质的先与基准面 B接触的一侧产生褶皱, 因此这种纠偏机构的可靠性差。 发明内容 本发明的目的在于提供一种可靠性高的薄片类介质纠偏机构及具有该机构的薄片 类介质处理装置。 为此, 根据本发明的一方面, 提供了一种薄片类介质纠偏机构, 位于薄片类介质 的输送通道内, 输送通道的沿薄片类介质宽度方向的一侧面为基准面, 该纠偏机构包 括电机、 在输送通道上沿输送方向间隔布置并且分别驱动与之接触的薄皮类介质向基 准面移动的多个纠偏辊、 与电机传动连接的多个摩擦传动组件, 各所述摩擦传动组件 一一对应地摩擦驱动各纠偏辊, 使得在薄片类介质与基准面接触时、 靠近该接触位置 的纠偏辊与对应的摩擦传动组件之间传动打滑。 进一步地, 上述多个纠偏辊同轴线地或轴线平行地设置, 各纠偏辊的轴线与基准 面呈夹角设置。 进一步地, 上述多个纠偏辊是两个或两个以上的纠偏辊。 进一步地, 上述各摩擦传动组件设置在与其对应配合的纠偏辊的支撑轴上, 其中 支撑轴与电机传动连接。 进一步地, 上述各摩擦传动组件包括与支撑轴相连的摩擦件和向贴近纠偏辊的方 向偏压摩擦件的压簧。 进一步地, 上述纠偏辊上设有空腔, 摩擦件和压簧位于空腔内。 进一步地, 上述薄片类介质纠偏机构还包括抬升纠偏辊远离薄片类介质的抬升机 构。 进一步地, 上述抬升机构包括与纠偏辊的支撑轴固定套接的凸轮, 该凸轮在支撑 轴转动一周的过程中抬升纠偏辊一次。 进一步地, 上述薄片类介质纠偏机构还包括可转动的转板和向转板偏压的弹性元 件, 支撑轴枢接在转板上并且远离转板的转轴, 在弹性元件的作用下, 各纠偏辊具有 按压在薄片类介质上的趋势。 进一步地, 上述薄片类介质纠偏机构还包括支架, 其中, 转板通过转轴枢接在支 架上, 电机设置在支架上, 电机与在支架上设置的传动轴传动连接, 传动轴与各支撑 轴之间传动连接。 根据本发明的另一方面, 提供了一种薄片类介质处理装置, 包括在输送通道上设 置的输送辊组、 纠偏机构和至少一处理机构, 该纠偏机构为根据上面所描述的薄片类 介质纠偏机构。 根据本发明提供的薄片类介质纠偏机构, 包括在输送通道的输送方向上间隔布置 并且分别驱动与之接触的薄皮类介质向基准面移动的多个纠偏辊、 与电机传动连接的 多个摩擦传动组件, 各摩擦传动组件一一对应地摩擦驱动各纠偏辊, 各纠偏辊驱动薄 片类介质向基准面移动, 当薄片类介质的一端与基准面接触时, 受该接触点阻碍, 与 靠近该接触位置的纠偏辊对应配合的摩擦传动组件传动打滑, 该纠偏辊减速或停止转 动, 其他纠偏辊继续转动, 驱动薄片类介质以该接触点为圆心转动, 直至薄片类介质 的一边完全与基准面对齐。 本发明提供的薄片类介质纠偏机构, 由于当薄片类介质的 一端先与基准面接触时, 受该接触点的阻碍,靠近该接触点的纠偏辊减速或停止转动, 避免了继续驱动薄片类介质运动导致的先与基准面接触的薄片类介质发生褶皱的问 题, 因此提高了薄片类介质纠偏机构的可靠性。 除了上面所描述的目的、 特征、 和优点之外, 本发明具有的其它目的、 特征、 和 优点, 将结合附图作进一步详细的说明。 附图说明 构成本说明书的一部分、 用于进一步理解本发明的附图示出了本发明的优选实施 例, 并与说明书一起用来说明本发明的原理。 图中: 图 1是中国专利申请 200510121474.2提供的薄片类介质纠偏机构的结构示意图; 图 2是根据本发明第一实施例的薄片类介质纠偏机构的结构示意图; 图 3是根据本发明第一实施例的薄片类介质纠偏机构的第一轴测图; 图 4是根据本发明第一实施例的薄片类介质纠偏机构的第二轴测图; 图 5是根据本发明第一实施例的薄片类介质纠偏机构的结构剖面图; 图 6是根据本发明第二实施例的薄片类介质纠偏机构的结构剖面图; 图 7a是根据本发明第一实施例的薄片类介质纠偏机构的纠偏辊组件位于第一位 置时的结构示意图; 图 7b 是根据本发明第一实施例的薄片类介质纠偏机构的纠偏辊组件位于第二位 置时的结构示意图; 图 8是根据本发明第一实施例的薄片类介质纠偏机构在初始状态时的示意图; 图 9是根据本发明第一实施例的薄片类介质纠偏机构在纠偏时的示意图; 图 10是根据本发明第一实施例的薄片类介质纠偏机构在完成纠偏时的示意图; 图 11是根据本发明第三实施例的薄片类介质纠偏机构的结构示意图; 以及 图 12 是使用本发明提供的薄片类介质纠偏机构的薄片类介质处理装置的结构示 附图标记说明

摩擦传动组件与电 机 11传动连接, 用于摩擦驱动纠偏辊 341。 摩擦传动组件包括摩擦件 342、 压簧 343, 以及垫片 344, 其中, 摩擦件 342与支撑轴 33固定连接, 当支撑轴 33转动时摩擦件 342随之同步转动, 摩擦件 342嵌入纠偏辊 341的空腔内, 摩擦件 342的一个端面与 纠偏辊 341 的空腔内的端面接触, 两者之间形成摩擦接触面; 压簧 343与支撑轴 33 套接, 其一端与摩擦件 342的另一个端面连接, 另一端与卡接在支撑轴 33上的垫片 344连接,压簧 343安装在支撑轴 33上后产生预定压缩量,使摩擦件 342与纠偏辊 341 紧密接触。 当支撑轴 33转动时, 摩擦件 342随之同步转动, 摩擦件 342与纠偏辊 341 之间的摩擦接触面上产生摩擦力, 驱动纠偏辊 341随摩擦件 342同步转动。 需要说明的是, 在本发明的其他实施例中, 如图 6所示, 纠偏辊组件 34'包括沿支 撑轴 33'轴向排列的纠偏辊 341 '和摩擦传动组件,其中,摩擦传动组件包括摩擦件 342'、 压簧 343', 其中, 纠偏轮 341 '远离转板 31', 摩擦件 342'位于纠偏轮 34Γ外部, 摩擦件 342'的一个端面与纠偏轮 341'的一个端面接触, 两者之间形成摩擦接触面, 压簧 343' 与支撑轴 33'套接, 其一端与摩擦件 342'的另一个端面连接, 另一端与转板 31'连接。 压簧 343'安装在支撑轴 33'上后产生预定压缩量,使摩擦件 342'与纠偏辊 341'紧密接触。 当支撑轴 33'转动时, 摩擦件 342'随之同步转动, 摩擦件 342'与纠偏辊 341 '之间的摩擦 接触面上产生摩擦力, 驱动纠偏辊 341 '随摩擦件 342'同步转动。 抬升机构 35可以为凸轮或者偏心件, 本实施例中抬升机构 35为凸轮。 抬升机构 35与支撑轴 33固定套接, 当支撑轴 33转动时, 抬升机构 35随支撑轴 33同步转动, 可与上通道板 73的上表面接触或分离,当抬升机构 35与上通道板 73的上表面分离时, 纠偏组件 3的转板 31在重力的作用下, 绕传动轴 21向靠近上通道板 73的方向转动, 使纠偏辊组件 34中的纠偏辊 341通过上通道板 73上的对应的缺口 731进入输送通道, 按压在输送通道内的薄片类介质上, 此时, 纠偏辊组件 34位于第一位置, 如图 7a所 示, 当纠偏辊组件 34的纠偏辊 341转动时,可以驱动薄片类介质在输送过程中向基准 面 B方向移动; 当抬升机构 35与上通道板 73的上表面接触时, 抬升机构 35驱动转 板 31绕传动轴 21 向远离上通道板 73的方向转动, 使纠偏辊组件 34中的纠偏辊 341 退出输送通道, 与薄片类介质分离, 此时, 纠偏辊组件 34位于第二位置, 如图 7b所 示。 需要说明的是, 当传动轴 21转动时, 各组纠偏组件 3的抬升机构 35与上通道板 73的相对位置一致, 即各组纠偏组件 3的抬升机构 35同步转动, 因此, 各组纠偏辊 组件 34同时位于第一位置或第二位置。 进一步地, 薄片类介质纠偏机构还包括检测组件 4, 用于检测纠偏组件 3的位置。 检测组件 4包括传感器 41, 传感器 41固定设置在支架上, 可以是光电式传感器, 也 可以是机械式传感器。 传感器 41与多组纠偏组件 3中的任意一组纠偏组件 3的转板 31的位置相对应, 当该组纠偏组件 3的转板 31绕传动轴 21在第一位置和第二位置之 间转动时, 转板 31可以与传感器 41分离或配合。 本实施例中传感器 41为马鞍形光电式传感器, 纠偏组件 3的转板 31在转动过程 中可以伸入传感器 41的凹槽中, 能够阻挡传感器 41的光发射器和光接收器之间的光 线传播路径。 当纠偏组件 3位于第一位置时, 传感器 41与转板 31分离, 传感器 41 发出第一检测信号, 如高电平, 当纠偏组件 3位于第二位置时, 转板 31插入传感器 41 的凹槽中, 阻挡了传感器 41 的光发射器和光接收器之间的光线传播路径, 传感器 41输出第二检测信号, 如低电平。 图 8是根据本发明第一实施例的薄片类介质纠偏机构在初始状态时的示意图, 图 9是根据本发明第一实施例的薄片类介质纠偏机构在纠偏时的示意图, 图 10是根据本 发明第一实施例的薄片类介质纠偏机构在完成纠偏时的示意图。下面结合图 8至图 10 介绍本发明提供的薄片类介质纠偏机构的工作原理。 如图 8所示, 初始状态时, 传感器 41输出第二检测信号, 薄片类介质纠偏机构的 各纠偏组件 3的纠偏辊组件 34位于第二位置,此时,各纠偏组件 3的纠偏辊 341均已 退出输送通道。 当薄片类介质进入输送通道后, 薄片类介质纠偏机构的控制器 (图中 未显示)控制电机 11的输出轴开始转动, 通过电机齿轮 12、 传动齿轮 22驱动传动轴 21转动, 传动轴 21通过各纠偏组件 3中的传动组件 32驱动支撑轴 33转动, 支撑轴 33带动摩擦件 342和抬升机构 35随之同步转动, 其中摩擦件 342驱动纠偏辊 341随 之同步转动, 抬升机构 35转动与上通道板 73的上表面分离, 在自身重力的作用下, 各纠偏组件 3的转板 31绕传动轴 21转动,使纠偏辊组件 34由第二位置切换至第一位 置, 即各纠偏辊 341通过上通道板 73上对应的缺口 731进入输送通道内, 按压在薄片 类介质上, 各纠偏辊 341转动驱动薄片类介质向基准面 B方向移动。 如图 9所示, 随着各纠偏辊 341驱动薄片类介质移动, 偏斜的薄片类介质的一端 首先与基准面 B接触(以下为便于描述,将首先与基准面 B接触的一端称为接触点 D), 受接触点 D处的基准面 B阻碍, 靠近接触点 D的纠偏辊 341的转动阻力加大, 当纠 偏辊 341的转动阻力大于摩擦件 342与纠偏辊 341之间的摩擦力时, 摩擦件 342与纠 偏辊 341之间相对打滑, 该纠偏辊 341停止转动, 此时, 其他纠偏辊 341继续转动, 驱动薄片类介质以接触点 D为圆心转动与基准面 B对齐。 如图 10所示, 当纠偏辊 341转动一周驱动薄片类介质沿基准面 B对齐时, 受基 准面 B的阻碍作用, 各纠偏辊 341与摩擦件 342之间均相对打滑, 各纠偏辊 341均停 止转动, 此时抬升机构 35转动一周再次与上通道板 73的上表面接触, 使各纠偏辊组 件 34随转板 31绕传动轴 21转动至第二位置时,各纠偏辊 341退出输送通道, 完成纠 偏。 本发明提供的薄片类介质纠偏机构, 包括电机组件、 传动轴组件, 以及至少两组 纠偏组件, 其中, 电机组件用于驱动纠偏组件中的抬升机构与上通道板接触或分离, 并通过传动轴组件驱动各纠偏组件中的纠偏辊转动以驱动薄片类介质与基准面对齐。 当抬升机构与上通道板接触时, 各纠偏辊组件位于第二位置, 各纠偏辊与薄片类介质 分离; 当抬升机构与上通道板分离时, 各纠偏辊组件位于第一位置, 各纠偏辊与薄片 类介质接触, 电机组件驱动各纠偏辊转动, 驱动薄片类介质向基准面 B移动, 当薄片 类介质的一端与基准面接触时, 受该接触点阻碍, 靠近该接触点的纠偏辊与对应配合 的摩擦件之间传动打滑, 该纠偏辊减速或停止转动, 其他纠偏辊继续转动, 驱动薄片 类介质以该接触点为圆心转动, 直至薄片类介质的一边完全与基准面 B对齐。 本发明提供的薄片类介质纠偏机构, 当薄片类介质的一端先与基准面接触时, 受 该接触点的阻碍, 靠近该接触点的纠偏辊减速或停止转动, 避免了继续驱动薄片类介 质运动导致先与基准面接触的薄片类介质发生褶皱的问题, 因此提高了薄片类介质纠 偏机构的可靠性。 图 11是根据本发明第三实施例的薄片类介质纠偏机构的结构示意图。 如图 11所 示, 本实施例与上述实施例相比, 不同之处在于, 本实施例中纠偏机构还包括弹性元 件 5。 弹性元件 5的一端与支架连接, 另一端与纠偏组件 3连接, 在弹性元件 5的弹 力作用下, 纠偏组件 3始终具有由第二位置向第一位置转动, 使各纠偏组件 3的纠偏 辊 341进入输送通道与薄片类介质接触的运动趋势。 本实施例中由于增加了弹性元件 5, 因此可以将纠偏机构设置在下通道板 74的背 离输送通道的一侧, 当凸轮与下通道板 74分离时, 在弹性元件 5的作用下, 各纠偏辊 341 同样能够进入输送通道, 因此本实施例提供的薄片类介质纠偏机构能够适应更多 的安装空间要求。 图 12 是使用本发明提供的薄片类介质纠偏机构的薄片类介质处理装置的结构示 意图。 如图 12所示, 薄片类介质处理装置包括纠偏机构 100、 在输送通道上设置的至 少一处理机构 200和输送辊组件, 以及驱动机构 (图中未示出)。 纠偏机构 100的结构形式及工作原理同上述实施例中所述, 在此不再赘述。 处理机构 200可以为打印机构、 扫描机构等薄片类处理机构中的一个或者多个的 组合。 本实施例中处理机构 200包括扫描机构 210和打印机构 220, 沿薄片类介质输 送方向, 扫描机构 210位于纠偏机构 100的下游, 打印机构 220位于扫描机构 210的 下游。 扫描机构 210包括相对设置的图像传感器 211和压纸件 212, 其中, 图像传感器 211设置在下通道板 74上, 压纸件 212设置在上通道板 73上, 图像传感器 211和压 纸件 212分别通过上通道板 73和下通道板 74上设置的缺口 (图中未示出) 伸入输送 通道, 两者相对配合, 当薄片类介质从图像传感器 211和压纸件 212之间穿过时, 图 像传感器 211可以获取薄片类介质的图像。 打印机构 220可以是热打印机构, 也可以是针式、 喷墨、 激光等打印机构。 本实 施例中打印机构为喷墨打印机构, 包括喷墨打印头 221和垫板 222, 其中, 喷墨打印 头 221设置在上通道板 73上, 垫板 222沿垂直于薄片类介质输送方向延伸, 并与下通 道板 74浮动连接, 喷墨打印头 221的打印端面与垫板 222分别通过下通道板 74和上 通道板 73上的缺口(图中未绘出)伸入介质输送通道,两者相对设置且间隔设定距离, 薄片类介质可以从两者之间通过, 当喷墨打印头 221沿垫板 222的延伸方向往返运动 时,通过喷墨打印头 221的喷嘴将墨汁喷射在薄片类介质上, 形成设定的图像和文字。 输送辊组件包括第一辊组 91、 第二辊组 92和第三辊组 93, 沿薄片类介质输送方 向依次布置在输送通道上, 用于输送薄片类介质在输送通道内运动, 其中, 沿薄片类 介质输送方向, 第一辊组 91位于纠偏机构 100的下游, 第一辊组 91包括相对设置的 主动辊 911和从动辊 912, 以及用于驱动从动辊 912抬起或落下的驱动组件 (图中未 示出), 其中, 从动辊 912与纠偏机构 100位于输送通道的同一侧, 当纠偏机构 100 进行纠偏操作时, 从动辊 912在驱动组件的驱动下向远离主动辊 911的方向移动, 与 主动辊 911间隔预定距离,薄片类介质可以被输送进入从动辊 912和主动辊 911之间, 当完成纠偏操作后, 从动辊 912在驱动组件的驱动下落下, 从动辊 912与主动辊 911 相切, 薄片类介质从两者之间穿过, 此时主动辊 911转动, 驱动薄片类介质向下游移 动。 驱动机构包括第一驱动机构和第二驱动机构(图中未示出)。其中第一驱动机构与 第一辊组 91、 第二辊组 92、 第三辊组 93传动连接, 用于驱动各辊组转动; 第二驱动 机构与打印机构 220传动连接, 用于驱动喷墨打印头 221沿垫板 222延伸方向 (即介 质宽度方向) 往返移动。 下面介绍薄片类介质处理装置的工作过程。 薄片类介质处理装置的控制机构控制纠偏机构 100的电机 11的输出轴转动,驱动 各纠偏辊 341和抬升机构 35随之同步转动,抬升机构 35转动与上通道板 73的上表面 分离, 在自身重力的作用下, 各纠偏辊组件 34绕传动轴 21由第二位置向第一位置转 动,使各纠偏辊 341通过上通道板 73上的缺口 731进入输送通道, 并与薄片类介质接 触, 各纠偏辊 341转动驱动薄片类介质向基准面 B方向移动, 当薄片类介质的一端与 基准面接触时, 靠近该接触点的纠偏辊 341与对应的摩擦件之间传动打滑, 该纠偏辊 341减速或停止转动, 其他纠偏辊 341驱动薄片类介质以接触点为圆心转动, 直至沿 基准面 B对齐。 当抬升机构 35转动一周后, 抬升机构 35再次与上通道板 73的上表 面接触, 使各纠偏辊组件 34随转板 31绕传动轴 21转动至第二位置时, 各纠偏辊 341 退出输送通道, 完成一次纠偏动作。 薄片类介质沿基准面 B对齐后第一驱动机构驱动各辊组 91、 92、 93转动, 位于 纠偏机构 100下游的第一辊组 91将对齐后的薄片类介质输送到扫描机构 210。扫描机 构 210的图像传感器 211获取薄片类介质表面图像,通过 OCR识别判断薄片类介质真 伪, 并将判定为真的薄片类介质的图像存档保存。 由于纠偏机构完成纠偏后各纠偏辊 341退出输送通道, 因此, 不会干扰位于纠偏机构 100下游的输送辊组输送薄片类介 质。 当完成扫描操作后,位于扫描机构 210下游的第二辊组 92转动,将薄片类介质输 送到打印机构 220, 在薄片类介质运动过程中, 第二驱动机构驱动打印机构 220的喷 墨打印头 221沿垫板 222的延伸方向往返移动, 在薄片类介质表面打印出设定图像或 文字。 完成打印操作后,位于打印机构 220下游的第三辊组 93将薄片类介质送出薄片类 介质处理设备。 使用本发明提供的薄片类介质纠偏机构, 由于在对齐操作中当薄片类介质的一端 与基准面接触时, 靠近该接触点的纠偏辊减速或停止转动, 因此避免了现有的纠偏机 构中在薄片类介质先与基准面接触的一端由于纠偏辊继续转动导致的该端褶皱的问 题, 因此, 提高了薄片类介质处理设备的可靠性。 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。
