Description

一种烟支水分密度重量分布特性综合筛分仪及综合筛分方法 技术领域
本发明涉及卷烟产品质量检测技术领域，具体涉及烟支水分密度重量分布特性综合筛分仪及综合筛分方法。
背景技术
在卷烟生产过程中，烟丝经过卷接机吸丝成型系统后，卷烟的烟丝束的水分密度重量分布发生变化。而目前为了提升卷烟产品的质量和客户满意度，卷烟生产企业通常会组织若干评吸人员对成品烟进行评析打分。在组织评析会前，需对烟支进行均一性处理，以保证评吸人员所得烟支的水分密度重量的客观一致性，从而减少对评析有效性的影响。目前，国内卷烟生产企业通常是单一的对烟支烟丝的水分密度重量进行考察，没有一个综合的针对这三项指标的筛分平台。
除此之外，现有技术中测量烟支重量的称重装置，在对烟支进行称重前，烟支是在重力下自动掉入秤盘，称重完成后烟支从秤盘中顶出在重力作用下再掉入分选装置中。如果不采取相应措施，烟支在掉落后会发生冲击可能导致烟丝松散甚至脱落。这样就导致，即便在称重时测量的烟支重量是准确的，但是经称重后，拿到评吸人员手中的烟支重量却不不同的。因此，如何保持无损的非破坏性检测烟支重量的的准确性和稳定性，非常关键，而现有技术中的称重装置明显违反了无损原则。综上开发一种具有缓冲机构的称重装置显得十分必要了。
现有的烟支分选装置，烟支从称重装置完成称重，直接落到分选装置的接料盒中，由于重力的作用，烟支在掉落过程中会出现烟丝掉落的问题，除此之外，烟支在掉落过程中经常出现不能顺利落入对应的接料盒中，需要人工辅助。分选出的烟支凌乱，需要人工整理，效率低，且在掉落或者人工整理过程中对烟支还会产生损伤，这就导致原本上一步检测过程中确定的水分密度重量相似度高的烟支，真正落到接料盒中后，烟支的上述指标并不一致，影响下一步试验使用。
为了解决以上问题，提出本发明。
发明内容
通过烟支水分密度重量分布特性综合筛分仪可快速自动从若干烟支样品中找出三因素分布特性最接近的样品。仪器采用高精度传感器提取烟支的重量，水 分和密度三因素分布特性值，然后通过综合比对算法找出相似度最高的样品，最后在分选装置的帮助下将相似度最高的样品放入指定容器中。
本发明根据烟支均一性前处理的目的特性，对烟支的检测和筛分过程应该是无损的。基于此，对烟支水分和密度的测量采用无损微波法，用电子天平对烟支进行精确称重。整机具有结构紧凑，运行可靠高效等优点。
本发明第一方面提供一种烟支水分密度重量分布特性综合筛分仪，其包括料斗1、微波装置2、称重装置3、分选装置4和最外层的机箱5；
所述料斗1用于容纳待分析的烟支样品；
所述微波装置2位于所述料斗1下游，其用于测量烟支的水分和密度；
所述称重装置3位于所述微波装置2下游，其用于测量烟支的重量；
所述分选装置4位于所述称重装置3下游，其用于将水分、密度和重量一致的烟支分选到一起。
优选地，其还包括智能设备6，所述智能设备6可以依据烟支的水分、密度和重量数据对烟支进行分类，并且控制所述分选装置4对烟支进行分选。智能设备6可以为电脑计算机。
其中，本发明所述料斗1和所述微波装置2采用组合式设计，两者直接相连。使得结构紧凑简单，运行过程少，效率更高。具体的所述料斗1和所述微波装置2的结构可以参考现有的专利申请。
此处的微波传感器采用谐振腔微波传感器，当样品通过微波谐振腔会引起微波频率的偏移，测量频率偏移量即可计算出被测样品的水分和密度。并且微波测量法是全域扫描式的，可以精确测量到每一毫米。
本发明的关键点并不在于料斗和微波装置的具体结构，本发明首创的设计了具有天平秤盘和缓冲机构的称重装置3和抽屉型多档烟支分选装置4，其中称重装置布置在微波装置出料口处，进一步减少中间转运烟支过程。分选装置布置在称重装置的下方，布置有6各分选通道。
称重装置3适用于烟支水分密度重量分布特性综合筛分仪中，起到承上启下的关键作用。基于综合筛分仪中称重装置上游的微波测量机构和下游的分选装置系上下垂直布置的关系，并且烟支是在重力下自动掉入秤盘，称重完成后烟支从秤盘中顶出再掉入分选装置中。两个机构之间存在较大的高度落差，如果不采取 相应措施，烟支在掉落后会发生冲击可能导致烟丝松散甚至脱落，这明显违反了无损原则，本发明的缓冲机构十分必要。
称重机构的主体是电子天平，精度为0.1mg。本发明采用了耙状V型槽结构的秤盘来接住并盛装烟支样品，同时缓降杆从旁辅助起到导向作用。称重后烟支被拨杆挤出秤盘掉在缓降杆上，缓降杆通过可控的旋转将样品缓慢放入分许机构中，避免了过大的冲击能量。
称重装置3适用于烟支水分密度重量分布特性综合筛分仪中，起到承上启下的关键作用。为了连接上下机构，本发明专门为天平设计了专用的秤盘和拨烟装置，同时配置了烟支缓降装置，防止烟支摔落导致烟丝脱出。同时本发明中天平秤盘和缓冲机构两者工作相对独立，互不影响。在完成烟支的称重，还可以利用缓冲机构使烟支缓慢下落到分选装置中，避免烟支下落过程中由于碰撞出现松散甚至脱落的现象，起到承上启下的关键作用。

具体实施方式
下面结合实施例对本发明作进一步的详细描述。
本领域技术人员将会理解，下列实施例仅用于说明本发明，而不应视为限定本发明的范围。实施例中未注明具体技术或条件者，按照本领域内的文献所描述的技术或条件或者按照产品说明书进行。所用材料或设备未注明生产厂商者，均 为可以通过购买获得的常规产品。
为了更好地了解本发明的目的、结构及功能，下面结合附图，对本发明一种具有天平秤盘和缓冲机构的称重装置做进一步详细的描述。
如图1所示，烟支水分密度重量分布特性综合筛分仪包括料斗1、微波装置2、称重装置3、分选装置4和最外层的机箱5；所述料斗1用于容纳待分析的烟支样品；所述微波装置2位于所述料斗1下游，其用于测量烟支的水分和密度；所述称重装置3位于所述微波装置2下游，其用于测量烟支的重量；所述分选装置4位于所述称重装置3下游，其用于将水分、密度和重量一致的烟支分选到一起。
烟支水分密度重量分布特性综合筛分仪还包括智能设备6，所述智能设备6可以依据烟支的水分、密度和重量数据对烟支进行分类，并且控制所述分选装置4对烟支进行分选。智能设备6可以为电脑计算机。
上述烟支水分密度重量分布特性综合筛分仪的使用方法，包括以下步骤：
(1)将待分析的烟支样品容纳于所述料斗1中；
(2)利用所述微波装置2测量烟支的水分和密度；
(3)利用所述称重装置3位测量烟支的重量；
(4)通过所述分选装置4将水分、密度和重量一致的烟支分选到一起。
具体工作流程为：首先，打开仪器的电源等待电脑自动启动并进入专用控制软件，然后接入并检查气压是否正常。准备烟支样品并整齐装入料斗中，滤嘴端靠左，然后在控制软件中设置好每个接料盒的样品参数范围，点击开始按钮后，仪器会自动完成测量比对和筛分。
具体到料斗机构动作中，开始工作后，料斗中的扰动轮将持续旋转直到测量结束。扰动轮上的扰动钉将对料斗堆积区中的样子样品产生扰动作用，防止样品架桥妨碍料斗的连续送料过程。
在料斗的作用下，烟支会自动落入推杆头部前方的V型槽内且烟支端部正对推杆头。推杆被设置在特定位置，其最高处于竖直方向不高于最细烟支的高度。推杆和电缸滑块连接，在电缸的驱动下推杆做直线运动推动烟支穿过微波传感器，从而采集到样子样品的水分和密度数据。推杆继续推动样品完全闯过微波传感器通道，是烟支样品停留在出料翻斗中。在电机的驱动下，出料翻斗旋转将烟 支放入称重机构的天平秤盘中。
待烟支在秤盘V槽中稳定后，天平完成烟支的称重。拨杆在电机的驱动下旋转将烟支从秤盘V槽中顶出，烟支将掉在缓冲杆上。通过缓冲杆的旋转将烟支缓慢下放并掉入分选装置的接料手中。
分选装置的接料手处于秤盘位置下方并正对缓冲杆的出料口，此时接料手翻转挡板处于关闭状态，烟支将掉在接料手槽内。然后旋转气缸旋转调整接料手角度，使得接烟支方向和料盒方向正对，然后电缸开始移动将接料手移动到对应的接料盒上方并保持，此时，接料手气缸控制翻转挡板打开接料手，烟支将掉入下方料盒中，完成烟支的分选。之后，接料手原路返回默认位置等带一下次分选。
如图2-7所示，一种具有天平秤盘和缓冲机构的称重装置，其包括称重台31，所述称重台31上设置有天平秤盘和缓冲机构；
所述天平秤盘包括电子天平32和秤盘33；
所述电子天平32一端连接有所述秤盘33，所述秤盘33包括多个齿耙结构的钩齿331，所述钩齿331上具有第一V形槽3311，烟支7水平放置在所述第一V形槽3311内进行称重；
所述缓冲机构包括拨杆344、前挡板35和缓降杆36；
所述拨杆344和所述缓降杆36连接形成拨动缓降组件，两者之间夹角形成第二V形槽342，且所述第二V形槽342位于所述第一V形槽3311下方，当烟支7在所述第一V形槽3311内进行称重时，所述拨杆344和所述缓降杆36均不接触烟支7；以免影响烟支7的称重。
所述拨动缓降组件位于相邻两个所述钩齿331之间，即所述拨动缓降组件和所述钩齿331相互交错设置；
所述前挡板35位于所述秤盘33一侧，所述前挡板35设有多个条状孔351，所述缓降杆36穿过所述条状孔351与所述前挡板35之间形成第三V形槽361；
所述缓冲机构的运动过程为：
当烟支7在所述第一V形槽3311内称重后，所述拨杆344和所述缓降杆36可沿两者连接点朝所述前挡板35方向旋转，使所述缓降杆36在所述条状孔351中从上至下移动，所述拨杆344拨动所述第一V形槽3311内的烟支7顺着所述缓降杆36移动到第三V形槽361，所述缓降杆36继续旋转，直至所述缓降杆 36完全脱离所述前挡板35，此时所述第三V形槽361消失，所述缓降杆36和所述前挡板35之间形成狭缝362，烟支7通过所述狭缝362脱离所述缓冲机构，完成对烟支的称重和缓降。
钉耙状的秤盘和拨杆以及缓降杆装置，确保烟支7在下落过程中速度可靠较慢，不会发生过度冲击，防止烟丝松散以致脱落。
所述拨杆34与所述缓降杆36形成的所述第二V形槽342呈90°夹角。
多个所述钩齿331朝向所述前挡板35。
所述称重台31上设置有拨杆电机341，所述拨杆电机341可控制拨杆344带动缓降杆36朝向所述前挡板35一侧旋转。
所述狭缝362宽度等于或大于烟支7直径时，烟支7通过所述狭缝362脱离所述缓冲机构。
所述钩齿331为片状，所述拨杆34为条状，所述缓降杆36为圆柱状。
在称重过程，所述缓冲机构运动前，所述拨杆344低于所述第一V形槽3311，所述缓降杆36高于所述第一V形槽3311，此时所述缓降杆36起到导向限位作用，防止烟支7在从上一个工序掉落至所述第一V形槽3311时，在惯性作用下跑出所述秤盘33。
控制所述缓降杆36的旋转速度即可控制烟支7的下落速度，达到烟支7缓降的效果。
利用本发明一种具有天平秤盘和缓冲机构的称重装置对烟支7进行称重和缓降方法，其包括以下步骤：
a、烟支7在从上一个工序掉落至所述第一V形槽3311内，通过所述电子天平32对烟支7进行称重；
b、称重后，启动所述拨杆344和所述缓降杆36朝向所述前挡板35方向旋转，所述拨杆344使所述缓降杆36在所述条状孔351中从上至下移动，所述拨杆344拨动所述第一V形槽3311内的烟支7移动到第三V形槽361；
c、所述缓降杆36继续旋转，直至所述缓降杆36完全脱离所述前挡板35，此时所述第三V形槽361消失，所述缓降杆36和所述前挡板35之间形成狭缝362，当所述狭缝362宽度等于或大于所述烟支7直径时，烟支7通过所述狭缝362脱离所述缓冲机构。
为了连接上下机构，专门为天平设计了专用的秤盘和拨烟装置，同时配置了烟支7缓降装置，防止烟支7摔落导致烟丝脱出。
秤盘是用薄板组合成V槽状的耙状体，拨杆是用条状材料组成的耙状体。秤盘和拨杆两耙状体相互交错布置，拨杆的待机位置低于秤盘V槽。烟支7从微波翻斗掉出后会落入秤盘V槽中并完成称重，之后烟支7在拨杆的驱动下被顶出秤盘。
缓降杆和拨杆是连接在一起的，两杆呈90°夹角。拨杆处于待机位置时，缓降杆正好位于秤盘V槽之上。因此，烟支7从微波翻斗掉下过程中，缓降杆将起到导向作用，防止烟支7跑出秤盘V槽范围。
在拨杆将烟从秤盘V槽顶出后，烟支7在重力作用下将掉在缓降杆和前挡板组成的V槽内。控制拨杆电机驱动缓降杆缓慢旋转，烟支7将顺着前挡板慢慢下落，以达到防止烟支7过度摔落的目的。
缓降杆继续顺时针旋转直至和前挡板脱离并且间隙大于烟支7直径后，烟支7将从缓降杆脱离并掉落，正好进入分选装置接料手中。
在电机的驱动下，出料翻斗旋转将烟支7放入称重装置的天平秤盘中。此时，拨杆和缓降杆处于图4的位置，缓降杆起到限位导向作用，防止烟支7冲出。
待烟支7在秤盘V槽中稳定后，天平完成烟支7的称重。拨杆在电机的驱动下旋转将烟支7从秤盘V槽中顶出，烟支7将掉在缓降杆和前挡板形成的槽内。通过缓降杆的旋转将烟支7缓慢下放并掉入分选装置的接料手中。

所述烟支承接槽417为由旋转挡板411和固定挡板412形成的V形槽结构。
所述接料手41还包括挡板气缸414，其可驱动所述旋转挡板411旋转，使所述旋转挡板411和所述固定挡板412之间角度变化，从而将所述烟支承接槽417中的烟支掉落到所述接料盒421中；
所述旋转挡板411运动过程中所述固定挡板412是固定不动的，从而使所述 烟支承接槽417的角度发生变化，当将所述烟支承接槽417的角度小于或等于180°时，其用于承接烟支；当所述烟支承接槽417的角度大于180°时，其可以将烟支掉落至所述接料盒421内。
所述旋转挡板411旋转时，所述旋转挡板411和所述固定挡板412之间间距也产生变化，在接烟时，所述接料手41的V形槽处于关闭状态，所述旋转挡板411与所述固定挡板412间保持一定的间距，其间距小于最细烟支的直径，如果有烟丝掉落或其他碎屑，可以从间距种掉落，以保证所述接料手41可长时间有效的运行，放烟时，打开所述接料手41的V形槽，所述旋转挡板411与所述固定挡板412间的间距大于最粗烟支的直径。控制旋转挡板和固定挡板之间的间距，并使旋转挡板和固定挡板保持一定的间距，如果有烟丝掉落或其他碎屑，可以从间距种掉落，以保证所述接料手41可长时间有效的运行，完成烟支筛选，方便快捷。
所述烟支承接槽417的长度大于或等于烟支的长度；所述接料盒421y轴方向的长度大于或等于所述烟支承接槽417的长度。
所述接料盒421可以从所述接料槽42中取出。
本发明一种抽屉型多档烟支分选装置的分选方法，其包括以下步骤：
A、所述接料手41沿所述一维运动平台43沿x轴方向移动，使所述接料手41位于不同的所述接料盒421一侧；
B、所述烟支承接槽417可从x轴方向旋转至y轴方向，即从所述接料盒421一侧旋转至所述接料盒421正上方；所述烟支承接槽417可承接烟支并将烟支掉落在所述接料盒421中；
C、推拉所述抽屉面板44，可带动所述接料盒421沿所述接料盒导轨45沿y轴方向移动，可以放置和取出所述接料盒421，或者取出所述接料盒421中的烟支；
以上各步骤不分先后顺序。
当接料手41位于放烟位16时，所述接料手41的V形槽位于所述接料盒421的正上方，通过所述挡板气缸414驱动所述旋转挡板411，所述接料手41的V形槽打开，烟支落入接料盒421内，即可完成放烟动作。
分选装置布置在称重装置秤盘下方，接料手正对秤盘，烟直接掉入接料手槽 内。整个分选装置做成抽屉状机构，可以方便的向前方拿出，方便维护保养和料盒的取出。
接料手使用两块薄板组合成的V型槽，其中一块板固定不动，另一块可在气缸驱动下旋转打开或关闭V槽，从而完成接烟或放烟动作。接料手打开两挡板间距小于最细烟支的直径，接料手打开后两板最小间距大于最粗烟支的直径。接料手无论开闭都存在着一定间隙，如果有烟丝掉落或其他碎屑，可以从间隙中掉下，长时间运行的可靠性更高。
考虑到接料位和放料位两个位置之间存在90°夹角，接料手是安装在旋转气缸上的，根据需要可以调节接料手的方向。于此同时，旋转气缸又安装在一维运动平台(电缸)的滑块上，通过电缸驱动可以将接料手移动到任意一个接料盒上方，从而完成烟支的分选。
分选装置的接料手处于秤盘位置下方并正对缓冲杆的出料口，此时接料手翻转挡板处于关闭状态，烟支将掉在接料手槽内。然后旋转气缸旋转调整接料手角度，使得接烟支方向和料盒方向正对，然后电缸开始移动将接料手移动到对应的接料盒上方并保持，此时，接料手气缸控制翻转挡板打开接料手，烟支将掉入下方料盒中，完成烟支的分选。之后，接料手原路返回默认位置等带一下次分选。
可以理解，本发明是通过一些实施例进行描述的，本领域技术人员知悉的，在不脱离本发明的精神和范围的情况下，可以对这些特征和实施例进行各种改变或等效替换。另外，在本发明的教导下，可以对这些特征和实施例进行修改以适应具体的情况及材料而不会脱离本发明的精神和范围。因此，本发明不受此处所公开的具体实施例的限制，所有落入本申请的权利要求范围内的实施例都属于本发明所保护的范围内。
