Description

用于生产泡罩包装的起泡机
技术领域
本发明涉及一种用于生产泡罩包装的起泡机。
特别地，本发明有利地应用于容纳药剂，如药片、胶囊、药丸、片剂等的泡罩包装产品，下面的描述将在不丧失其共性的前提下涉及这种包装。
背景技术
目前，根据图1(现有技术)的用于生产泡罩包装的已知起泡机M包括：站1，在这里可热成形材料(如PVC)的第一连续带2被热成形以形成带有容纳产品4的泡罩(blister)3的泡罩带，泡罩带2沿着具有可变线路的确定的进给路径A连续地进给；用于进给产品4的站5，其具有以相应产品4填充每个泡罩3的单元；用于进给连续的第二带7(如铝带)的站6，用于在填充有产品4的泡罩带2上方连续地进给第二连续带7；站8，用于通过热封使泡罩带2和第二带7封闭在一起，以便得到连续的泡罩包装带NB。
沿着具有可变线路的进给路径A，在封闭站8的下游还设有站9和站10，在站9连续泡罩包装带NB被模压或冲压，在站10连续泡罩包装带NB被预切割，以便在该连续泡罩包装带NB上形成预切割线。
之后，带有预切割线的连续泡罩包装带NB例如通过在切割站R切割而被分开，从而形成多个单独的泡罩包装B。
在切割站R的下游，单独的泡罩包装B被提取并被送到盒子单元C，以便通过已知的方式被包装在适当的盒子中。
通常，封闭站8具有两个相对的彼此关联的辊子，即封闭站8包括第一驱动辊子12，其位于下部并带有凹槽，即具有用于容纳带有产品4的泡罩3的圆周凹槽12a；和第二辊子13，其位于驱动辊子12对面并在驱动辊子12上方，并且具有加热装置，用于在泡罩带2和第二带7彼此叠置时加热和施压使它们接合。
可从图1的起泡机M看出，两个带的接合将导致在相对的辊子12、13之间的切线上形成连续泡罩包装带NB，同时由于泡罩包装带NB沿限定在驱动辊子8a外周表面上的宽圆弧接触，当拉动泡罩包装带NB时得到有效的夹紧。带NB被驱动通过转向辊子11、沿进给路径A的锐角部分并向封闭站8的下游，并且形成了一环路K。
形成环路K并允许由驱动辊子12最佳夹紧在带NB上的张紧辊子11还可在不同的工作位置之间摆动，以便允许补偿带NB沿路径A的连续进给；这种摆动是必要的，这是因为带2和7连续进给，从而带NB连续进给，带NB的连续进给必需与在已知的起泡机中以间歇方式进行的模压站9和预切割站10的操作相配合。
发明内容
本发明的目的是提供一种起泡机，相对于上述已知的起泡机来说，它的结构更简单并且更紧凑，这导致尺寸显著降低。
特别地，本发明的一个目的是简化带封闭站的结构和功能，以便提高整个起泡机的生产速度。
本发明的另一个目的是改进带封闭站的结构，消除由于带的热接合而引起的泡罩带发生破坏性弯曲的可能性。
本发明的又一个目的是改进带封闭站的结构，以避免在密封接合过程中仍是热的封闭带和泡罩内部的产品之间的接触。
根据本发明，一种用于生产泡罩包装的起泡机，其具有一生产线，该生产线顺序包括：至少一个可热成形材料的第一连续带的热成形站，以形成带有容纳产品的泡罩的泡罩带；用于进给所述产品并以所述产品填充所述泡罩带的站；第二带的进给站，用于在填充有所述产品的所述泡罩带上方连续地进给第二带；封闭站，在这里所述泡罩带由所述第二带密封，以便得到泡罩包装带，所述封闭站包括两个相对的辊子，所述两个相对的辊子是驱动辊子和密封辊子；和切割站，在这里所述泡罩包装带被切割成各个泡罩包装；所述生产线至少从用于进给所述产品的站处开始，沿基本上水平的连续进给路径延伸，并且所述起泡机包括张紧装置，所述张紧装置沿所述路径位于所述封闭站的上游，以便与所述封闭站的所述驱动辊子和密封辊子协作，从而至少在所述泡罩带上执行确定的张力，所述起泡机的特征在于，所述张紧装置包括一对辊子，所述张紧装置的一对辊子彼此面对并且位于至少所述泡罩带的相对两侧上，所述张紧装置的所述一对辊子的至少一个辊子是动力驱动辊子；所述张紧装置的所述一对辊子至少在所述泡罩带上执行所述张力，以便沿着由所述泡罩带的至少一个泡罩和在所述密封站的所述驱动辊子上制成的相应的座确定的线的正确的和完全的配合，并且所述起泡机包括用于检测和控制所述泡罩和在所述封闭站的所述驱动辊子上制成的所述座之间的配合的检测控制装置；所述检测控制装置反作用在所述张紧装置的所述一对辊子上，以便致动所述张紧装置的所述一对辊子，即在所述检测控制装置检测到所述座和所述泡罩的错误配合时在所述泡罩带上产生制动张力。
附图说明
根据上述目的的本发明的技术特征从下面权利要求的内容可得到清楚地了解，并且本发明的优点将从下面参照附图的详细说明中更好地看出，这些附图示出了纯粹是作为非限定性例子的优选实施例，其中：
图1是已知起泡机(现有技术)的示意性透视图；
图2是由本发明提出的起泡机优选实施例的示意性前视图；
图3是形成为图2的起泡机的整体部件的工作站的优选实施例的前部局部断面图，其中为清楚起见移除了一些部件；
图4是图3的特定工作站的详细侧视图；和
图5是图3和4的工作站一部分的工作组的侧面断面图。
具体实施方式
参照图2，标记M1总体表示由本发明提出的起泡机，其用于生产容纳产品，优选是药物的泡罩包装。
为了使对本发明提出的起泡机M1和现有技术的起泡机M之间的比较的描述变得简单和清楚，以与用于描述起泡机M的相同附图标记(在存在的地方和可能存在的地方)加上基数100来描述和表示图2所示的起泡机M1的构成元件，因此数字101表示起泡机M1的热成形站，它与表示现有技术起泡机M的热成形站的数字1相对应，等等。
因此，起泡机M1由一生产线来限定，该生产线包括：站101，在这里可热成形材料(如PVC)的第一连续带2被热成形，以便得到带有容纳产品104的泡罩103的泡罩带102，该泡罩带102沿着预定的进给路径A1以基本上连续的方式进给；用于进给产品104的站105，其具有用相应产品104填充每个泡罩103的单元；第二带107(如铝带)的进给站106，用于在填充有产品的泡罩带上方连续地进给第二带；封闭站108，在这里由第二带107通过热封封闭第一泡罩带，以便得到连续的泡罩包装带NB1。
沿着线性进给路径A，在封闭站108的下游还设有至少一个站109，在这里连续泡罩包装带NB1被模压或冲压，并且优选地还设有站110，在这里连续泡罩带NB1被预切割，以便在该连续泡罩包装带NB1上形成预切割线。
之后，带有预切割线的连续泡罩包装带NB1例如通过在切割站R1处切割而被分开，从而形成多个单独的泡罩包装B1。
模压站109和预切割站110优选地被操作用于在带NB1上连续工作，被连续地驱动，这是因为模压/切割装置从泡罩带NB1连续移动以及连续移动至泡罩带NB1，并且跟随带NB1。
在切割站R1的下游，单独的泡罩包装B1被提取并被送到盒子单元(已知但未示出)，以便通过已知的方式被包装在适当的盒子中。
通过图2的本发明的起泡机M1和图1所示的现有技术的起泡机M的比较，可以容易地看出，尽管起泡机M的路径A具有可变线路(例如在与带NB的环路K相应的区域中成锐角的弯曲路径，其通过使转向辊子11摆动而形成)，但是起泡机M1中的泡罩带102的进给路径A1至少从站105处开始水平地延伸，以用于进给产品104。
换句话说，仅在视觉上就允许理解，起泡机M1的生产线是水平的，即它以更简单且更紧凑的方式来构造，因此显著降低了现有技术的起泡机M通常占据的尺寸。
根据图3和4，用于密封泡罩带102和第二带107的封闭站108具有一对辊子112、113，该对辊子相对于泡罩带102、第二带107布置在相对的侧面。
位于下面的辊子112是驱动辊子，其具有用于接收泡罩带102的泡罩3的凹槽112a，而位于辊子112对面并且与辊子112协作的上部辊子113是热封辊子。
特别地，应该注意到，在沿水平路径A1的进给过程中，驱动辊子112沿着单线与泡罩带102完全接合，其中该单线相应于与密封辊子113接触的线T。
再根据图3，相对于沿着路径A1的进给动作，在封闭站108的上游，起泡机M1包括用于张紧泡罩带102和第二带107的张紧装置114。
张紧装置114允许所述泡罩带102和第二带107以最佳的张力水平地前进，从而允许泡罩带102、第二带107在封闭站108中有效地相互接合，而不会滑动，并且通过驱动辊子112的座112a在泡罩103上实现最佳的夹紧和驱动作用，尽管泡罩带102仅可以在与接触线T对应的区域中附着于驱动辊子112。
根据图4和5，张紧装置114包括一对辊子116、117：下部辊子116是动力驱动辊子并且它的横断面具有至少两个环116a和116b，用于保持泡罩带102的边缘。
动力驱动辊子116在接收到由检测控制装置115(图4)发出的指令信号S时实际上用作泡罩带102的制动元件，其目的在于检查泡罩103和驱动辊子112上制成的容纳座112a之间的正确配合。
上部辊子117与动力驱动辊子116相配合，并且在它的旋转中，具有挤压装置118(图5)，用于将受控的压力施加在动力驱动辊子116上：通过这种方式，可以改变压紧动力驱动辊子116的压力。
再根据图4，检测控制装置115被布置在与驱动辊子112对应的区域中，并且反作用在张紧装置114上，以便允许张紧装置的致动，即在检测控制装置115检测到座112a-泡罩103的错误配合时产生对泡罩带102的制动张力。
检测控制装置115优选地但非限定地包括光学传感器，其位于驱动辊子112的附近并且沿单个座112a-泡罩103的配合线T作用。
所述光学传感器优选地是激光发射器，并且所述激光仅在座112a-泡罩103的配合错误的情况下通过光电池120反射。
因此，起泡机M1通过这种方式被构造以便实现所述目的，这是因为封闭站108的简单和有效的结构。
可以仅在两个辊子的一条接触线上执行密封，其中带子在封闭站的下游以及上游呈水平地一个位于另一个之上，这使得最终的泡罩包装具有较高的质量，消除了泡罩包装的不合乎需要的弯曲，并且实时控制带子的正确通过的张紧/制动单元的存在提供了密封的可靠性。
此外，由本发明提出的具有上述封闭站的起泡机可生产带有细长泡罩的泡罩包装(例如用于容纳胶囊)，而无需在封闭站使用具有多刻面外周表面的驱动辊子，所述具有多刻面的外周表面在泡罩包装上引起不希望有的沟纹和/或在产品和封闭带的那些在密封后仍然热的部分之间的损坏接触。
最后，由于带子相对于所有工作站的连续进给，并且这些工作站同样也是连续工作的，显著地改进和优化了由本发明提出的在起泡机中的产品进给，消除了对产品的损坏。
所构思的发明能容许多种改变和变化，所有这些都落在本发明的构思之内。但是，所有的细节均可通过技术等效元件来替代。
