Description

纸巾分配器的幅片改变机构
技术领域
本发明涉及一种用于纸巾分配器的机构，该机构当在实际分配辊上不再有纸时，送入幅片状(web-like)的纸巾，使该纸巾从补充辊前进。
发明内容
该分配器包含至少两个辊，实际分配辊和补充辊。该分配器的补充工作过程包括将该实际分配辊作为剩余辊转移至为它在分配器中设置的空间，从而使该补充辊占据该剩余辊的先前位置。只要辊是空的，从这个新位置纸继续从该剩余辊分配。另外，当该剩余辊为空的时，纸继续从该补充辊转移，进行分配。
分配辊上的纸量根据多么经常地使用该分配器而变化，并且当根据定制的补充计划检查和工作该分配器时，在分配辊上可包含相当数量的纸巾纸。显然，这个纸巾量是因消耗而精确地使用的，与检查计划无关。
在相关的纸巾分配器中，纸作为连续的幅片放在辊上，该分配器包括将该幅片切成固定的分配长度和从装置上分配这些依次的长度以便当需要时作为手巾使用的机构。该分配切刀机构可以为完全机械驱动的和通过将粘附在分配器上的纸巾拉出而手动驱动的。还已知为此目的使用电分配器。
在这些装置中，分配片形状的纸巾幅片的系统的基本结构和工作原理是相同的。该系统的基本元件为放置在要分配的幅片的横向的分配鼓轮，并且通过分配动作使该幅片支承在其圆周表面上。该鼓轮是转动的，并带有在该鼓轮的转一圈过程中分配一个巾片长度的装置。该鼓轮的直径确定所分配的巾片的长度。
该装置还包括引领辊和压紧辊，后者与该鼓轮的边缘轻轻地接触。通过这些辊与该鼓轮的圆周接触的自由转动，或利用适当的回转机构，可使这些辊和该鼓轮的圆周速度同步，使其基本上相等。通常，该鼓轮的圆周表面带有适当的摩擦装置，例如加工得粗糙或用摩擦涂覆层覆盖。
在该鼓轮上设有刀片机构，用于在分配动作过程中切断或刺穿幅片。该刀片机构放置在该鼓轮圆周的轴向槽中，可围绕与该鼓轮的轴向方向平行的自身的轴线转动。该刀片机构包括放置在其轴线末端的杠杆臂，并且该杠杆臂的突出端跟随分配器壳体的内壁上的稳定的凸轮表面。通过跟随这个凸轮表面，该杠杆臂使切刀围绕其轴相对于该鼓轮的实际转动位置转动。在分配鼓轮的给定的回转角度范围内，该刀片从该鼓轮圆周突出，位于该鼓轮圆周表面下面的给定范围内。该刀片的切削刃为锯齿形，即，该刀片利用其三角形的齿逐渐地穿透至幅片中，充分的切断效果在刀片转动至完全突出的该鼓轮的回转位置时实现。
由于来自使用者的拉动作用，要分配的幅片牢固地放置在分配鼓轮的圆周表面上，该作用可被可能的导向辊的制动作用增强。
如果分配器使用的量和补充工作计划合理同步，则当使纸巾分配器工作时，在分配位置通常有几乎完全空的纸巾幅片辊，而且在为该辊设置的并在先前工作中使用的空间中，有空的剩余辊的芯以及末端销。清理该剩余辊空间并将实际的部分消耗的分配辊运动至这个空间。可以不中断幅片在分配鼓轮上的分配状态进行这个转移步骤。将完全新的补充辊送入该部分消耗的分配辊的先前位置，从而该部分消耗的辊作为剩余辊继续分配。使该补充辊上的幅片的前端通过，达到在该分配器的前部中的准备使用的位置，当在该剩余的分配辊上再没有纸时，该改变机构将该幅片的前端推至该分配鼓轮上。
这个改变机构的从该剩余辊至该补充辊的基本部件在所附权利要求的特征部分中说明。
附图说明
现参考附图更详细地说明本发明，其中，
图1为根据本发明的纸巾分配器的基本部分的示意图，和
图2表示从不同角度看的基本上相同的基本部分。
具体实施方式
图1表示按常规原理工作的纸巾分配器。该分配器处在刚接受补充工作(supplementation service)的状况中。在补充工作的过程中，将在该装置上部的分配工位中部分消耗的纸巾幅片辊(web roll)1搬至剩余辊位置，但保持幅片6准备从这个辊继续前进。整个纸巾幅片辊10放置在该装置的上部，幅片11的前端进入准备使用位置，幅片改变机构可从该位置送进纸巾幅片辊10进行分配。
该装置包括作为基本部分的分配鼓轮7，该分配鼓轮7具有纸幅片6，该纸幅片6将要在该分配鼓轮的圆周表面上运行并从分配孔伸出而被分配、切断或刺穿成一定长度。当该纸幅片运行时，它由导向辊3和压紧辊4和5导向。该压紧辊与分配鼓轮的圆周表面轻轻地压紧接触。如上所述，切断刀片9放在分配鼓轮上，沿着分配鼓轮的一圈的给定部分，从鼓轮7的圆周表面突出，穿透鼓轮上的幅片6并在其上穿孔。
在幅片6不再从剩余分配辊1运行的情况下，用于在鼓轮7上以幅片11代替幅片6的改变机构包括一同工作的几个部件。第一，它包括挡板12，该挡板在重力作用下下降并利用铰链12a与装置的壳体连接。工作时，该挡板12基本上在水平位置。该挡板12的突出端由从剩余分配辊1运行至分配鼓轮7的纸巾幅片6而支承在这个位置。该挡板12带有挡块15。基本水平的滑板13在弹簧作用下靠在该挡块上。滑板13上的弹簧载荷由受适当的压紧弹簧作用的压紧板14在箭头A方向上传递，使压紧板14围绕其固定点向着分配辊7转动。只要滑板13顶着挡板12的挡块15，滑板13可防止这个转动。
当装载该分配器时，补充辊10的幅片11的前端进入压紧板14的影响范围，即进入该压紧板和分配鼓轮之间的空间中。在这个结构中，当剩余的分配辊1变为空的且幅片6不再运行时，挡板12的突出端在重力影响下落下。这个落下使滑板13与挡块15松开，由该压紧板14和弹簧力A推动，该滑板向着挡板12的铰链点12a滑动。同样，压紧板14向着分配鼓轮运动，并使补充辊10的幅片11的前端到达分配鼓轮7的粗糙表面。当消耗者拉动幅片6的余下部分和使该鼓轮在这个拉伸作用下转动时，该幅片再在该鼓轮的圆周上运行。
挡板12必需能在铰链12a上翻起，使得该被部分地消耗的辊可毫无问题地从分配位置运动至剩余辊工位，并且不改变幅片6与辊未卷绕的情况。
纸巾分配器中的分配鼓轮7带有控制该鼓轮转动的偏心弹簧负载。当该鼓轮转动半圈时，激活该负载，并且在下一个半圈的过程中，释放其激活能。这种结构使该分配器具有简单的功能，即对于每一个分配的纸巾，该鼓轮7转动约一整转。
根据本发明的幅片改变机构也可在这样的纸巾分配器上实现：分配鼓轮上没有上述的纸巾幅片切断机构，而切断是通过在分配孔8处的撕裂运动进行的。
