Description

用于处理金属带的装置
技术领域
本发明涉及一种用于在金属带从具有液态的涂覆材料、例如锌的涂覆容器中离开之后处理金属带的装置。
背景技术
这种类型的装置在现有技术中基本上已知，即，例如从文献WO 2012/172648 A1和德国专利申请DE 10 2009 051 932 A1、DE 10 2007 045 202 A1和DE 10 2008 039 244 A中。具体地，这些印刷文献公开了一种涂覆容器，其被填充以液态的涂覆材料。为了涂覆，金属带被导引穿过具有涂覆材料的容器。在离开涂覆容器之后，金属带通过布置在涂覆容器之上的、用于吹刷附着在金属带的表面处的尚液态的涂覆材料的过多部分的吹刷设备(Abblaseinrichtung)或喷嘴。在吹刷设备之上，布置有也称为动态电磁覆层优化器DEMCO的由吹刷设备支撑的电磁稳定设备，以用于在离开涂覆容器和吹刷设备之后使带稳定。电磁稳定设备产生电磁力，借助于该电磁力将金属带保持在整个装置的中间平面的中心；以这种方式至少减小了在经过尤其吹刷设备期间的金属带振动。
然而，(除了在根据文献DE 10 2008 039 244 A1的结构之外)在该所描述的结构中在实际中存在如下缺点，电磁稳定设备很远地布置在吹刷设备之上。这就此而言是不利的，因为在吹刷设备中由稳定设备施加的稳定作用仅仅受限地到达金属带。此外，待由稳定设备产生的、需要用于在远离的吹刷设备的区域中稳定金属带的力在现有技术中相对大。与之相应地，用于使稳定设备运行的能量消耗也相对高。最终，不利的是，稳定设备布置在喷嘴载体(Düsenträger)或横梁之上，因为由此使在喷嘴载体的区域中接近金属带明显地变得困难。
发明内容
本发明的任务在于，如下改进用于处理金属带的已知的装置，即，明显地简化在喷嘴载体的区域中接近金属带。
该任务通过专利权利要求1的对象解决。
通过稳定设备在吹刷设备处的要求保护的更近的布置方案有利地实现，必须由稳定设备产生更小的力，以便在吹刷设备或喷嘴的区域中稳定金属带。由此，也减小了稳定设备的能量需求并且装置总体而言更有效。
也称为喷嘴载体的水平横梁装配在两个垂直的立柱之间。在横梁处，固定有吹刷设备，悬挂在横梁之下。稳定设备在横梁之下也悬挂地固定在该横梁处，然而在横梁和吹刷设备之间。稳定设备在横梁处的保持与吹刷设备在横梁处的固定无关。
不仅稳定设备而且吹刷设备在横梁之下的布置方案提供如下优点，即，对于操作人员而言可非常简单地接近在横梁之上的区域，并且由此也接近由横梁展开的用于金属带的通过的缝口。
根据第一实施例，吹刷设备和稳定设备到横梁处的分别独立的固定通过独立的移动设备实现。具体地，吹刷设备通过吹刷移动设备固定在横梁处，但是可相对于横梁移动。此外，稳定设备通过稳定移动设备固定在横梁处，但是可相对于横梁移动。两个移动设备分别实现了用于吹刷设备和稳定设备相对于装置的中间平面以及也相对于金属带的运动的不同自由度。两个装置尤其实现了吹刷设备和稳定设备相对于彼此的移动。除了通过吹刷移动设备和稳定移动设备实现的、用于相应的设备的独立的自由度以外，有利的是，横梁与悬挂在该处的吹刷设备和稳定设备一起可垂直移动地支承在垂直的立柱处。垂直的立柱可与横梁一起彼此平行地在水平的平面中移动。因为横梁以可围绕固定的转动点(固定侧)在水平的平面中摆动的方式支承在垂直的立柱中的一个处，并且横梁活动地支承在另一垂直的立柱处(活动侧)，也实现了横梁在水平的平面中的摆动。横梁的该自由度同样适用于吹刷设备和稳定设备，因为这两个所提到的设备固定在横梁处。
附图说明
描述附有两个附图，其中
图1示出了根据本发明的装置的宽度视图(Breitenansicht)，
图2示出了穿过根据本发明的装置的横截面，以及
图3和4示出了根据本发明的吹刷设备或根据本发明的电磁稳定设备的缝口的俯视图，分别带有金属带的理论中间位置和不同的非期望的实际位置的标记。
具体实施方式
下面参考所提到的附图以实施例的形式详细描述本发明。在所有附图中，利用相同的附图标记表示相同的技术元件。
图1示出了根据本发明的装置100。其包括两个侧向上的、垂直地延伸的立柱150，在所述立柱150处以可垂直地且水平地行进的方式支承有横梁130(也称为喷嘴载体)，见图1中的双箭头。此外，装置100可在水平的平面中摆动。为了该目的，两个立柱150中的一个构造成固定侧A，横梁以可围绕垂直的转动轴线摆动的方式支承在该固定侧A上。与此相反，相对而置的立柱构造成活动侧B并且仅仅垂直地支撑横梁。通过这种立柱作为固定侧和活动侧的构造方案，在金属带200处于倾斜时，可通过在水平面中摆动使装置100和尤其横梁140相对于该金属带200对称地取向。结果，横梁的宽侧应始终平行于金属带取向并且这两者相对于该金属带具有相同的距离。
吹刷设备110或喷嘴悬挂在横梁130处。不是刚性地，而是通过吹刷移动设备115实现吹刷设备110到横梁130处的联结(Ankopplung)，该吹刷移动设备115构造成，使吹刷设备110相对于横梁130在水平的平面中、也就是说尤其垂直于装置的中间平面160移动。此外，吹刷移动设备115构造成，使吹刷设备110围绕其自身的纵轴线L摆动并且由此合适地抵靠金属带200靠放。
在横梁130和吹刷设备110之间，也称为动态电磁覆层优化器DEMCO的稳定设备140通过稳定移动设备145固定在横梁处。该稳定移动设备145实现了稳定设备140在水平的平面中相对于横梁、尤其垂直于且平行于装置100的中间平面160的平移移动。附加地，稳定移动设备145也可构造成，使稳定设备140在水平的平面中相对于横梁130且相对于吹刷设备110围绕垂直的转动轴线摆动。
图2以横截面图示出了图1的根据本发明的装置。附图标记170表示用于操控稳定移动设备145的控制设备。可看出涂覆容器300，其基本上布置在装置100之下。待涂覆的金属带200在输送方向R上被导引到具有液态的涂覆材料310的涂覆容器300中，并且在此借助于转向辊320转向到垂直方向中。然后，该金属带从下向上首先通过吹刷设备110以及随后通过稳定设备140。本发明设置成，在稳定设备作用到金属带200上的最大力F的作用线和空气离开间隙112之间的距离d在200至800mm的范围中、优选地在300至500mm的范围中。
为了实现稳定设备140的经改变的定位或布置方案，显然可合适地匹配所有所需的电的和气动的供应管路或管走向。相同的也适用于不同的罩壳板。相对于已知的装置100，可需要的是，与在现有技术中相比，保持装置130-1,130-2例如以100mm进一步彼此远离，以便不仅可在保持装置之间的间隙中容纳稳定设备140，而且也可借助于稳定移动设备145实现其水平的可行进性(Verfahrbarkeit)或为此创造足够的空间。
吹刷设备110展开缝口122，金属带200被引导穿过该缝口122。借助于吹刷设备，从金属带200的表面吹刷过多的涂覆材料。
为了在金属带200的上侧和下侧上均匀地进行吹刷，重要的是，金属带200在预定的理论中间位置(也称为中间平面160)中通过吹刷设备120的缝口122，如其在图3中以在X方向上的实线的形式象征的那样。该理论中间位置尤其通过与吹刷设备120的缝口122的内边缘的均匀的距离或距离分布而出众。除了期望的预定的理论中间位置，在图3中也作为虚线绘出了金属带的可能的非期望的实际位置。那么，用于金属带200的非期望的实际位置在于，其相对于理论中间位置扭转或在Y方向上平行移位。
图4示出了可能的第三非期望的实际位置，在其中，金属带200相对于理论中间位置在X方向上、也就是说在宽度方向上平行地移位。
电磁稳定设备140自身具有缝口142，金属带200同样被引导穿过该缝口142。在此也适用的是，金属带200优选地在预定的理论中间位置160中通过缝口142，如在图3和4中示出的那样，以便通过电磁稳定设备140提供的力可以以期望的方式均匀地稳定地作用到金属带200上。对于缝口142以及在此也力求的理论中间位置而言，同样的如之前参考图3和4那样适用于所述的吹刷设备120的缝口122。
在稳定设备140和吹刷设备110之间此外布置有第一获取设备154以用于获取在吹刷设备110的缝口122中金属带200的实际位置与预定的理论中间位置的偏差。备选地，第一获取设备154也可构造成仅用于获取金属带的实际位置。此外，设置调节设备180，以用于如以上参考图3和4解释的那样，通过借助于吹刷移动设备115使吹刷设备110移动、也就是说通过使吹刷设备110悬挂在该处的横梁130移动，在吹刷设备的缝口122中将金属带200的实际位置调节到预定的理论中间位置128上。作为对所获取的偏差的响应进行调节。如果不是在第一获取设备154中进行实际位置与理论中间位置的偏差的获得，则其例如也可在调节设备180之内进行。根据所获取的在吹刷设备的缝口122中金属带的实际位置与预定的理论中间位置的偏差，在横向于金属带的输送方向R的水平平面中进行吹刷设备110的移动。另外表达成：如果确定金属带200不是在理论中间位置128中通过缝口122，则借助于吹刷移动设备115使吹刷设备110如此移动，使得金属带又在预定的理论中间位置128中通过吹刷设备的缝口122。为了该目的，如此构造第一获取设备154，以至于其优选地可获取所有三个以上参考图3和4描述的、与理论中间位置128偏差的金属带200的实际位置。
所述的吹刷设备110的移动不应作用到电磁稳定设备140上。为了该目的，构造控制设备170，其如此操控稳定移动设备145，使得电磁稳定设备140不在吹刷设备110相对于通过线参考位置(Passlinien-Referenzposition)移动的情况中一起行进，而是可保持在其原来的部位处。通过线参考位置160表示装置的固定定义的中间平面。与之相对地，理论中间位置128针对缝口122,142。因此，控制设备170如此作用到稳定移动设备145上，使得在吹刷设备110移动的情况中，电稳定设备140优选地进行与吹刷设备110刚好相反的运动，也就是说，结果优选地保持在其原来的部位处。
为了实现这种特殊类型的用于稳定移动设备145的操控，控制设备170可评估不同的情况。一方面，控制设备170可构造成，根据在吹刷设备110的缝口122中由第一获取设备154获取的金属带的实际位置与预定的理论中间位置的偏差，使电磁稳定设备140移动。
备选地或附加地，控制设备170可构造成，根据由第二获取设备155获取的吹刷设备120的移动且在相对于其相反的方向上执行电磁稳定设备140的移动。第二获取设备155用于获取吹刷设备110相对于装置100的通过线参考位置160的移动。
最终，根据另一备选方案或者补充地，控制设备170可构造成，根据在电磁稳定设备的缝口142中所获取的金属带的实际位置与预定的理论中间位置的偏差，引起电磁稳定设备140的移动。为此的前提是，存在第三获取设备156以用于获取在电磁稳定设备140的缝口142中金属带的实际位置与预定的理论中间位置的偏差。
第一、第二和第三获取设备154,155,156分别构造成，优选地识别金属带的实际位置与期望的理论中间位置的所有可设想的偏差。为此，尤其算上金属带在x或y方向上的(平行)移位或扭转，如以上参考图3和4解释的那样。相应地，(在合适地通过调节设备180或控制设备170操控时)构造稳定移动设备145和吹刷移动设备115，以任意方式使吹刷设备110和电磁稳定设备140在横向于金属带的输送方向R的水平平面中行进，尤其(平行)移位或围绕垂直的转动轴线扭转，以实现金属带在理论中间位置中的通过。
第一和第三获取设备154,156以及可选地附加地同样第二获取设备155可以以一个或多个光学的传感器设备190的形式实现。就此而言，传感器设备形成用于所提到的获取设备的结构单元。优选地，在电磁稳定设备140中每个线圈设置一个传感器设备190。典型地，对所有传感器设备的测量值取平均值。传感器设备190通常也可称为距离获取设备。
