Description

使撕开条与薄膜带连接用的装置
技术领域
本发明涉及一种用于使连续输送的材料条特别是撕开条与连续传送的材料带特别是薄膜带连接的装置，该装置用于生产带有撕开条的盒子外包装用的坯料，该材料条和材料带可以利用加热加压互相连接在一起。
背景技术
盒子常常围以用塑料薄膜或玻璃制成的外包装。当第一次使用此盒子时，利用撕开条除去该外包装。特别是香烟盒的外包装可以通过一条在周围缠绕的撕开条来拆开。活的胶粘剂。因此，撕开条与薄膜带的连接耗费时间并需要特殊的装置。
发明内容
本发明基于这样一种目的，就是改善在热量和压力下将材料条特别是撕开条附着在薄膜带上的过程，使得连续作用即使在较高的工作速度下也是可靠的。
为了达到这个目的，本发明的一种用于使连续输送的材料条特别是撕开条与连续输送的材料带特别是薄膜带连接的装置，用于生产带有撕开条的盒子外包装用的坯料，其中：
a)提供转动的压力和密封部件，以将该材料条压靠在材料带上，
b)该压力和密封部件为密封辊，
c)该密封辊主要或唯一地受到间接加热，
d)多个密封辊沿着材料带和材料条的传送方向连续地排列设置，
其特征在于：
e)在该连续的密封辊之间的区域、并且与该材料带或材料条隔开设置热传导部件，
f)所述热传导部件是沿该材料条的纵向延伸的薄壁、加热的连接片，
g)该连接片隔开距离沿着该密封辊的廓形设置，并沿着传送方向连续地设置。
根据本发明所述的装置的特征在于，压力和密封部件为加热的密封辊，它们主要或唯一地受到间接加热，特别是利用辐射热。
因此，在根据本发明所述的装置中，两种互相连接的材料即薄膜带和安置在薄膜带的精确位置上的撕开条通过压力辊和反向压力辊传送，至少压力辊是加热的。
在本发明的合适的实施例中，沿传送方向相继安置三个间隙加热的压力辊，而在它们的对面则相继安置三个反向压力辊。
本发明的特点在于，附加的-辐射-热转移到密封辊上并附加地转移到待连接的材料上，并因此转移到撕开条和材料带上。为此，设置薄壁连接片(thin-walled webs)作为传热部件，它们跟随密封辊的外形轮廓延伸在密封辊和离材料带或撕开条距离极小的端部之间。这些连接片(也)受座罩的加热。这些连接片将辐射热传递给材料带和撕开条。
本发明的进一步的细节是本发明的主题并将在下面参照附图更详细地说明。

具体实施方式
本示范性实施例特别良好地适合于生产具有外包装的香烟盒，该外包装是由带撕开条的玻璃纸或塑料薄膜制成的。图1表示作为包装机一部分的薄膜装置。
薄膜带10从卷筒11上连续拉出并被引导在多个转向辊和控制辊上。撕开条112、13与连续输送的薄膜带10结合，同时在连续输送期间在密封台14区域内在热量和压力下与薄膜带10连接。由薄膜带10和撕开条12、13组成的包装组合件(unit)被送入包装机或送入切割外包装坯料用的切割装置。
图1所示装置的特点在于该装置设计用于双路操作模式。从卷筒11上拉出的薄膜带10具有两倍宽度。在切割台15的区域中，材料带10利用中央纵向切割刀具分为两股相邻运行的一半宽度的薄膜带。这两股相邻的薄膜带10在铺展台16的区域内利用铺展辊17以这样一种方式转向，使得这两股薄膜带互相间隔一定距离地平行前进。
每股薄膜带10被分配给一个撕开条12、13。这些撕开条从分开的卷筒18、19抽出。在结合辊20区域中(该结合辊同时是两股薄膜带10的转向辊)，撕开条12和13与彼此相邻运行的被分配的薄膜带10结合。
具有联接在盒子的精确位置中的撕开条12、13的两股薄膜带10然后平行运行地被送入密封台14。在密封台14中，每股带有撕开条12、13的薄膜带10被分配到一个密封装置21中。每股比同一速度运行的连续传送的薄膜带10连接到压靠薄膜带10的撕开条12、13上。在密封台14的下游，两股各有一个压靠密封的撕开条的薄膜带10于是互相平行地输送并前进，以继续处理。
撕开条12、13以这样一种方式设计或以这样一种方式设有涂层，使得当加热加压时可以保证与薄膜带10的耐久连接。密封部件21这样设计，使得在连续输送薄膜带10期间对薄膜带10或撕开条12、13连续加热加压。
在目前的示范性实施例中，密封装置21在薄膜带10和撕开条12、13的直立分带22区域内起作用。沿薄膜带的传送方向，多个密封辊23、24、25一个接一个地沿薄膜带的纵向对薄膜带10和撕开条12、13起作用。在目前的情况下，三个密封辊23、24、25一个在另一个顶上地安置在一个共同的直立承载部件26中。密封辊23、24、25压靠撕开条12、13，因此在撕开条区域内间接地压靠薄膜带10、以便加压。
在薄膜带的与密封辊23和25对置的一侧，安置有反向压力辊即三个反向辊27、28、29。反向辊27至29每个刚巧安装在密封辊23和25的对面。在传送移动期间，薄膜带10和撕开条12、13利用密封辊23至25被压靠在反向辊27和29的周边上。密封辊23至25和反向辊27至29相对于薄膜带的传送速度受到驱动，因此作为传送移动的结果而受薄膜带10的转动。
密封辊23至25这样受热，使得除了压力外，密封辊23和25也传热。在目前的示范性实施例中，提供了密封辊23至25的间接加热，特别是利用辐射热。
承载部件26取座罩31的形式，它几乎完全包围密封辊23至25，也就是除了薄膜带10区域内通过密封辊23至25的密封表面用的小区域或开孔32以外。在目前情况下座罩31利用一个沿纵向延伸的加热筒33直接加热。该加热筒33安置在一个孔34中，该孔延伸在座罩中薄膜带10的对置侧上，紧邻密封辊23至25的周面。以此种方式加热的座罩31将热量传递给密封辊23至25。在上端部处，加热筒33装有一个电线用的接头35。
密封辊23到25用的座罩31是以特殊方式设计的，使得(辐射)热从座罩31直接传递到薄膜带10或撕开条12、13上。在目前的情况下，座罩31由两个平行的纵向壁36、37组成，其中装有密封辊23至25，后者带有螺栓形式的转动轴线38。如图所示，特别在图3和图4中，密封辊23至25的一个活动环39安装在带滚动轴承40的转动轴线38上。
两个纵向壁36、37利用横向连接螺栓41彼此连接在一起。这些螺栓延伸在座罩31的横向壁42区域内。在端部也就是在顶部和底部，该座罩31由端壁43封闭，因此密封轴23至25每个安装在内腔44中。后者只是在侧面也就是沿向着薄膜带10的方向开口(开孔32)。
以这种方式成形的座罩31其外部用绝热板45围绕，这减少对外界的热损失。绝热板45延伸在纵向壁36、37和端壁43的区域中。连接螺栓41通过绝热板延伸，使座罩31的单元和绝热板45由连接螺栓41固定在一起。同时，这些连接螺栓41用于连接所述单元和承载部件26，后者形成单臂杆的形式。因此，座罩31沿侧向固定在该承载部件26上。
在密封辊23至25之间设置了附加的部件，用于将(辐射)热传递到座罩31的面向薄膜带10的侧面上的撕开条12、13上。这些部件是连接片46，它们在撕开条12、13的区域内作为比较薄壁的部件精确也设置在座罩31上，也就是设置在横向壁42和端壁43上。连接片46做成这样的形状，使得它们以一定距离跟随密封辊23至25的外形轮廓，并以小距离例如1/5到1/2mm从撕开条12、13处伸出。结果，没有接触地传递了附加热量。
密封辊23至25以特殊方式设计。在外密封表面区域内形成一个运转的圆形密封条47(Sealing Web)。该密封条47近似地对应于撕开条12、13的宽度或稍宽。由于该密封条47，作为密封辊23至24外区的活动环39有一个T形截面。密封辊23至25的这部分由热导率高的金属材料构成。
在目前情况下，反向辊27至29只具有产生密封所需反向压力的作用。反向辊27至29也安装在具有轴颈49的运转轴承48上。这些沿侧向与座架30连接，后者取单臂杆的形式。
反向辊27至29具有比密封辊23至25更宽的外轴承面积或表面积。在图示的示范性实施例中，反向辊27至29的外周面做成弹性。图5表示，为此目的在反向辊27至29上固定一个用弹性材料特别是硅酮制成的套筒50。因此，薄膜带10利用密封辊23、24压紧弹性套筒50。如图所示，该套筒50在该区域内有一个凸起的外轴承表面51。
密封辊23至25和/或反向辊27至29安装成可以调节。在目前情况下，一方面是支承部件26而另一方面是座架30被设置成可以活动。角承载部件26可以转动地安装在静止的支承轴颈52上。在中断的情况下，密封装置21或带密封辊的承载部件26移出而与薄膜带10脱离接触，也就是通过枢轴式转动到图2中虚线所示的位置中。
反向辊27至29用的座架30可以转动地安装在支承轴颈53的一侧上。由于这种安装，带有反向辊27至29的座架30的相对位置可以进行调节。
