Description

用于制造由至少一种气体和至少一种液态的塑料组分构成的 混合物的装置
技术领域
本发明涉及一种用于制造由至少一种气体和至少一种液态的塑料组分构成的混合物的装置。
背景技术
这样的装置由EP 0 776 745 B1的图10得出。在那里，用于至少一种气体的引入机构以气体压力瓶的形式构造。用于至少一种液态的塑料组分的输送机构以泵的形式存在。在该文献的其它附图中也公开了活塞泵。所述至少一种气体和所述至少一种液态的塑料组分在活塞泵本身中混合。通过阀实施和调节气体的供应。如在该文献中描述的那样，很难将准确的气体量以正确的比例引入到液态的塑料组分中。
发明内容
本发明的任务是提供一种装置，在该装置中避免上面提到的问题。
该任务通过根据本发明的装置来解决。所述装置用于制造由至少一种气体和至少一种液态的塑料组分构成的混合物。所述装置包括用于所述至少一种液态的塑料组分的容器或输送泵并且包括气体源和混合机构，该混合机构经由第一线路与用于所述至少一种气体的引入机构连接并且经由第二线路与用于所述至少一种液态的塑料组分的输送机构连接，其中，所述引入机构和输送机构构造为具有活塞的活塞泵。将活塞泵不仅用于至少一种气体而且用于液态的塑料组分允许将气体精确地配量给液态的塑料组分。如果认为，用于液态的塑料组分的输送机构的活塞泵存在确定的最大填充体积，并且用于至少一种气体的引入机构的活塞泵存在确定的最大的填充体积(该填充体积可以等于输送机构的填充体积或者与输送机构的填充体积不同)，则可以通过压力影响供应给液态的塑料组分的气体量，利用该压力将气体填充到引入机构中。按照本发明的解决方案是成本较有利、设计较简单并且构造较小的。
原则上，引入机构的活塞泵和输送机构的活塞泵能以彼此独立的方式运行，从而可以单独地操控所述活塞泵。为了实现特别简单并且成本有利的实施方式，优选规定：引入机构的活塞和输送机构的活塞机械地或者电气地耦联。
对于所述耦联存在两种实施变型方案。在机械反向的耦联时规定：引入机构的活塞和输送机构的活塞这样耦联，使得在从引入机构输出气体时将液态的塑料组分引入到输送机构中并且在从输送机构输出液态的塑料组分时将气体引入到引入机构中。与此相比，在并行或者机械同步的耦联时规定：引入机构的活塞和输送机构的活塞这样耦联，使得在从引入机构输出气体时将液态的塑料组分从输送机构输出并且在将气体引入到引入机构中时将液态的塑料组分引入到输送机构中。
还要求保护一种用于制造发泡塑料件、特别是密封垫的设备，该设备具有按照本发明的、用于制造由至少一种气体和至少一种液态的塑料组分构成的混合物的装置。

具体实施方式
图1以其整体示意性地示出用于制造发泡塑料件、特别是密封垫的设备100。该设备100还具有多个重要的子单元。
一个这样的子单元由装置16形成，该装置用于制造由至少一种气体和至少一种液态的塑料组分构成的混合物。该装置16还具有至少一个混合机构17、经由第一线路18与混合机构17连接的引入机构19和经由第二线路20与混合机构17连接的输送机构21，该引入机构用于至少一种气体，该输送机构用于至少一种液态的塑料组分。此外，所述装置16具有用于塑料组分的容器53和气体源54、特别是压缩空气产生机构。代替容器53也可以设置有输送泵。
在这样的装置16中，与现有技术不同地规定，引入机构19和输送机构21构造为具有活塞22和23的活塞泵25和24。
引入机构19(活塞泵25)的活塞22和输送机构21(活塞泵24)的活塞23在该实例中经由增压器26机械地反向地耦联。该增压器允许使用在压力相对低时工作的(例如气动)驱动器，因为通过力传递实现所需的力提高。此外还可看出进口阀27、28和出口阀29、30。
如在图2中详细示出的那样，通过控制机构33与耦联的活塞22、23的运动相协调地操作所述进口阀27、28和出口阀29、30。还示出传感器31，该传感器经由信号线32与控制机构33连接以用于传输信号。传感器31用于确定增压器26的位置。因此，也确定活塞22、23的位置。也可以通过传感器31直接确定活塞22、23的位置(见其它实施例)。通常，当在引入机构19的活塞22和气缸35之间的活塞密封件、在输送机构21的活塞23和气缸34之间的活塞密封件和/或至少一个所述阀27至30磨损时，可以利用这样的传感器31进行泄漏识别。为了泄漏识别例如关闭气体侧的进口阀28和出口阀30。通过活塞22对处于进口阀28和出口阀30之间的气体体积实施压缩。如果存在泄漏，则在进行压缩之后发生增压器26的不规则运动，该不规则运动被传感器31探测。此外，可以检查在液态的塑料组分中是否存在不规则的气体成分，因为这些不规则的气体成分在进口阀27和出口阀29关闭时导致活塞23运动，因为液态的塑料组分能被所述不规则的气体成分压缩。这必要时可以通过控制机构33来平衡。
图3示出单个活塞泵，该活塞泵同时形成用于输送机构21的活塞泵24和用于引入机构19的活塞泵25。在该变型方案中不存在单独的增压器，更确切地说，一个活塞不仅形成活塞泵24的活塞23而且形成活塞泵25的活塞22。按照图3的系统也机械地反向地工作。亦即，当气体经由(下面示出的)引入机构19输出时，将液态的塑料组分引入到输送机构21中并且反之亦然。
与此相比，图4示出一个系统，在该系统中活塞泵24和25机械地同步地耦联。具体地，引入机构19的活塞22和输送机构21的活塞23经由耦联机构63这样耦联，使得在从引入机构19输出气体时将液态的塑料组分从输送机构21输出并且在将气体引入到引入机构19中时将液态的塑料组分引入到输送机构21中。
图5示出活塞泵24和25的电子耦联。在此，活塞22和23的运动被控制机构64控制，该控制机构与两个活塞泵24和25的驱动机构在信号技术上连接。活塞22和23可以反向地或者同步地运动。这能通过控制机构64调节。
图6示出活塞泵25和活塞泵24，这两个活塞泵分别交替地形成引入机构19或者输送机构21。在此优点在于：在两侧上交替地通过液态的塑料组分涂抹密封件。可以在预先给定的循环次数之后进行交替。所述交替通过切换机构65和66进行，所述切换机构要么可以手动切换要么优选通过控制机构67、优选有规则地切换。在第一切换位置中，将液态的塑料组分从容器53经由第一线路68输送至(上面示出的)活塞泵24，而将气体从气体源54经由第二线路69输送至活塞泵25。就此而言，整个系统在所述第一切换位置中与图1和图2一致。不过，在第二切换位置中进行线路改变。具体地，在所述第二切换位置中，将液态的塑料组分从容器53经由第三线路70输送至(下面示出的)活塞泵25，而将气体由气体源54经由第四线路71输送至活塞泵24。因此，在所述第二切换位置中(与在第一切换位置中相反)，活塞泵25形成输送机构21并且活塞泵24形成引入机构19。于是，根据切换位置，经由第一线路18或者第二线路20将液态的塑料组分或者气体继续泵吸至混合机构17。
返回到图1，设备100的另一个子单元由装置36(其为配量机构38提供优选与气体混合的、液态的塑料组分)形成。所述装置36具有用于至少一个液态的塑料组分的源37。优选所述源37由线路形成，该线路从已经提到的混合机构17引导离开。此外，所述装置36具有用于至少一种液态的塑料组分的、间歇性工作的传送机构。所述间歇性工作的传送机构由活塞泵24、25形成，但也可以是其它任意构造的适用于间歇性传送液态的塑料组分的装置。间歇性工作的源不仅要理解为其输送功率会下降到零的源(例如活塞泵)，而且也要理解为其输送功率经受特别是脉冲式波动的源(例如齿轮泵)。
此外，装置36具有配量机构38、优选配量泵，由传送机构提供塑料组分给所述配量机构。此外，装置36具有设置在用于至少一种液态的塑料组分的源37和配量机构38之间的缓冲机构39，该缓冲机构具有可变的缓冲体积40，通过该缓冲机构将间歇性输送至缓冲机构39的液态的塑料组分始终以足够的量在足够的预加压力下提供给配量机构38。在配量机构38之后，塑料组分到达配量阀60，由此塑料组分直接地(见虚线示出的喷嘴61)或者如在图1中示出的那样间接地经由另一个混合元件58、经由喷嘴61输出并且通过输出和随之产生的压力下降而发泡。
为了能实现尽可能保持不变的传送，优选规定：能通过缓冲机构39来控制在缓冲机构39和配量机构38之间在液态的塑料组分中存在的压力。液态的塑料组分从源37经由进口41到达缓冲机构39的缓冲体积40中。缓冲体积40又经由出口42与配量机构38连接。在图1中，进口41构造在缓冲机构39的壳体43的壁中。这同样在图7中可见。但是，备选地也可以规定：进口41构造在缓冲机构39的与活塞45连接的活塞杆44中(见图8)。此外，在进口上游设置进口阀51并且在出口42下游设置出口阀52。此外，可以设置行程传感器72，利用该行程传感器至少能确定活塞45在壳体43中的选取的位置。
此外规定：在配量机构38的输出侧上设置有压力传感器46。所述压力传感器46经由控制线48与控制机构47连接。控制机构47这样控制缓冲机构39，使得施加在配量机构38的输入侧上的压力跟踪在配量机构38的输出侧上存在的压力。此外，控制机构47可以这样构造，使得不仅关闭进口阀51而且关闭出口阀52并且压缩处于缓冲体积40中的液态的塑料组分。此外，可以设置有未示出的传感器，通过该传感器能探测到缓冲体积40的无规则的压缩。
此外，缓冲机构39与用于对缓冲机构39加载压力的机构49连接。所述机构要么能被控制机构47(虚线画出的线路)操控，要么能被独立的控制机构50操控。
原则上，对于制造呈密封垫形式的发泡塑料件来说，两个装置16和36已经足够。但是，可以附加地优选地规定：第二塑料组分与第一塑料组分并行地或者与第一塑料组分混合地优选在物理上发泡成塑料件。因此，设备100的另一个子单元由用于多组分发泡的装置62形成(再次见图1)。所述装置62具有用于第二塑料组分的容器55，将优选与气体混合的第二塑料组分从该容器经由配量机构56和配量阀57引导至混合元件58。在该混合元件58中，将所述第二塑料组分与第一塑料组分混合。接着，将所述混合物在另一个配量阀59之后经由示意性示出的喷嘴61输出，由此包含在混合物中的气体发泡。换言之，由于所述输出而发生压力下降，气体使液态的塑料组分发泡并且在发泡塑料组分硬化之产生例如呈密封垫73形式的、设有气孔的塑料件。
在配量阀57和/或60中同样可以设置有止回阀，该止回阀在图1中设有附图标记51和52用作进口阀和出口阀。
