Abstract
借助用于将液态涂料涂敷到一涂敷面上、尤其是用于将分散涂料涂敷到墙壁上的装置来运用一方法,在该方法中,涂料滴以液滴形式撞击该涂敷面并且在该涂敷面上交互流动形成涂料膜。
Description
技术领域
本发明涉及用于在涂敷面上涂敷液态涂料、尤其用于在墙壁上涂敷粘滞的涂料的方法,以及涉及用于实施该方法的装置。
背景技术
在墙壁上的涂料、尤其是粘滞的分散涂料的涂敷在专职工人以及家庭作业者的范围中将借助涂料辊、喷射***,借助涂敷毛刷或海绵***来实现。不管使用这些***中的哪种,都需要费事的工作准备。对此主要有用于涂料涂敷边界的粘贴,例如在门框上,以及所有其它物体及区域的覆盖,如家具及地板,以避免受涂料飞沫的损害。首先当不同的涂料以专门的形状或将在相互分界的区域上涂敷时,涂料涂敷边界的维持也是困难的。
本发明的公开内容
本发明的任务在于,给出一种方法及所属的装置、也即一个***,借助该***可在通常情况下无液滴地及在预定的轮廓中达到覆盖的、均匀的涂料涂敷,以致首先可尽可能地取消费事的粘贴及覆盖工作。
该任务将通过根据权利要求1的方法,尤其是在使用根据权利要求5的装置的情况下来实现。
根据本发明的方法,用涂料滴脉冲式地、优选在数量级约为100脉冲/秒的脉冲频率的情况下撞击涂敷面,并且是这样的,即涂料以液滴形撞击在涂敷面上及在该液滴形消散的情况下交互流动地形成了一个均匀的涂料膜。因此在根据本发明的方法中,以液滴近似壁毯式地覆盖涂敷面,其中,这些液滴沿涂敷面扩展,近似地沿涂敷面漫散及交互过渡,以致构成一个封闭的一致的涂料膜。由此消除了涂料耗损,因为仅消耗了要用于撞击所需的涂料量。
即使涂料膜厚度主要通过预压力、撞击能量及撞击频率来确定,但在撞击涂敷面时各涂料滴彼此的距离也参与相应的涂料膜厚度的确定,以及该距离优选稍小于涂料滴在撞击墙壁时的直径。合乎目的地有约20%的重叠。在相应地选择适配于进给速度的撞击序列时,沿涂敷面得到涂料滴对涂敷面的无重叠的覆盖,并且基本上仅借助一个被控制的涂料计量装置。
而合乎目的的是,根据液滴大小、液滴速度,涂料稠度和/或其它参数如尤其是涂料的粘度来调节或可调节到涂敷面的工作距离,必要时也在工作运行中有控制地改变该工作距离。
为此尤其可用传感器来监测涂敷面和/或在涂敷面上形成的涂料膜,其中,尤其可使用通过对比度传感器和/或颜色传感器的相应的传感器监测,以便检测预定的涂料涂敷边界以及将涂料滴的撞击限制在相应分界的区域上。
为了实施根据本发明的方法,优选地使用根据权利要求6的装置来工作,该装置具有相对涂敷面保持预定距离的、对着涂敷面的及在涂敷面上分布地设置的涂料喷嘴,这些涂料喷嘴脉冲式地被控制,并且将被压力加载的涂料以液滴形式对着涂敷面喷出以及以液滴形式施加到涂敷面上。
这种装置可以在结构上非常紧凑地构成,从而该装置也可作为以封闭结构形式构造的手持式装置来使用并且除了涂料涂敷喷嘴外还包括用于待涂敷的涂料的储备容器及控制装置与泵装置,它们允许根据预先的规定脉冲式地进行涂料涂敷喷嘴的液滴喷射,必要时也包括为控制及监测涂料均匀涂敷的合乎目的的传感式监测装置。根据本发明的装置不仅可构成无电缆的手持式装置,而且也可结合***装置来一起使用,并也可由电网供电。为此可设置一个与服务站的接口,并且不仅涉及涂料供给也涉及能量供给,其中涂料供给装置可与涂料准备装置和/或过滤装置相连接。
在本装置中,涂料涂敷喷嘴优选设置在该装置的壳体的底部区中,其中对于涂料涂敷喷嘴合乎目的地这样布置,即,这些喷嘴横向于工作方向成列地延伸。
各个喷嘴列合乎目的地位于该装置的底部区的相对在涂料涂敷时的进给方向上在后部的、靠近边缘的区域中,以致可用简单的措施达到该装置的相对涂敷面有支撑的导向,而对已涂敷的涂料膜无不利的影响。
关于涂料以液滴形式到涂敷面上的施加,被证实合乎目的的是,仅设置一列涂料涂敷喷嘴,其中这些涂料涂敷喷嘴相互的距离约相当于液滴直径的大小,但优选地大于液滴直径及约在液滴直径1.5倍的范围中。并且多个喷嘴列的结构亦在本发明的范围内,其中设有喷嘴的共同的、分组的或单独的控制和/或供给装置,其中优选地普遍设置相同的喷嘴距离。
本装置的相对涂料涂敷面以预定距离的导向可通过在底部侧对本装置设置的滚子来实现,其中这种导向装置有时也可这样构成,使得相对涂敷面的距离可被调节,也可以在工作中根据参数来改变该距离。
涂料涂敷喷嘴的底部侧的、相对壳***于边缘附近的列布置被证实是合乎目的的,以便可通过侧向的导向装置、尤其是滚子在邻接于凸起如门框等的工整的轮廓中涂敷涂料,以致至少在很大程度上使附加的粘贴工作和/或覆盖工作成为多余。
被证实合乎目的的还在于,设置在边缘附近的喷嘴列相对底面以轻微的斜率向外倾斜地布置,即布置在相对工作方向在底部区或装置所属壳体的后部的边缘区域中,以致可在凸起上不用转移地接着进行涂料涂敷。
通过根据本发明设置的传感器装置也可检测出对凸起或类似物即涂料边界的接近,或检测出用于涂料涂敷的边界线,必要时也可将涂料涂敷喷嘴打开及关闭。该装置在适配相应的工作条件中的可变性尤其可与涂料涂敷喷嘴的有控制的关断性相结合地这样来扩展,即对该装置的横向侧中的至少一个配置另外一喷嘴列,以致可用一个这样的横向侧邻接于凸起或类似物如门框地进行涂料涂敷。
根据本发明的对涂料涂敷的传感式检测也可被用来:有目的地监测涂料涂敷;为个别喷嘴的失效发出信号,及必要时还用于:在真正的工作过程期间、但也可随后,在修补意义上有目的地在识别出的空缺部位上进行涂料涂敷。
尤其对于这种工作、但也完全普遍地,合乎目的的是,对设置成列的喷嘴横向于相应喷嘴列的延伸方向地提出交替的偏移,即也可提出喷嘴列的之字形分布,其中,在本发明的范围内,尤其对于修补工作等可合乎目的的是:除了横向于工作方向延伸的、设在边缘附近的喷嘴列外,还设有一个或多个附加的喷嘴列,这些喷嘴相互相应地偏移。
附图说明
其它的优点及合乎目的的实施形式可由权利要求书,附图及对附图的说明中得知。附图表示:
图1:根据本发明的一个装置的底部侧的透视图,
图2:根据图1的装置的部分区段的俯视图,其中表示在沿一个墙壁面的凸起,这里为一个墙壁开关涂敷涂料时的一个工作附件,
图3:在用根据本发明的装置沿一个边界线工作时的概要视图,该边界线延伸在不同着色的涂料区域之间,沿该边界线在一个涂料区域中进行涂料涂敷,及
图4及5:一个喷嘴及配置给该喷嘴的用于脉冲地涂敷涂料的机构的概图。
具体实施方式
图1表示根据本发明的用于在涂敷面上涂层地涂敷液态介质、尤其涂料的装置1,该涂敷面被装置1在其上面扫过。该装置1在其构型方面被概要表示成一个可自给自足地使用的手持式工作机,它具有一个包括底部区3的壳体2。喷嘴开口4位于该底部区3中,这些喷嘴开口对着相应的涂敷面,该涂敷面在图3中用标号5指示。
在作为一个优选构型的该实施例中,装置1沿从底部侧看为矩形的壳体2的边缘6布置及为了简明起见通过一连串的点来表示,以致喷嘴开口4在该实施例中被表示为喷嘴列7。
在所示实施例中,列7的喷嘴开口4沿从底部侧看为矩形的壳体2的纵向侧8排成一排,其中,纵向侧8横向于运动方向9,在通常情况下在涂敷面5上涂敷涂料时,装置1沿该运动方向运动。在这样的涂料涂敷时,装置1在箭头10的方向上运动,以致喷嘴列7相对于在涂料涂敷时的工作方向(箭头10)位于壳体2的后部的纵向侧8附近。原则上该装置1也可沿其它方向运动。
在底部区3中,在喷嘴列7与相对箭头10所示的工作方向在前的纵向侧11之间设有间隔保持单元12,这些间隔保持单元优选通过支承在底部区3中的滚动体、尤其是球形滚动体来构成,其中,如图所示,对于这些间隔保持单元12,分布在底部区3上被证实是有利的,如图所示,例如三条腿式的支撑能实现装置1在涂敷面5上稳定的导行。
底部区3优选地在周围被壳体2的边缘以向着涂料涂敷面5的方向上的小的超出高度包围,其中,尽管有该超出高度,但通过间隔保持单元12仍保证装置1沿涂料涂敷面5的自由移动性。这种边框可合乎目的地作为飞沫保护,但也用于使底部区3相对周围环境尽可能地隔离,以避免在涂料涂敷时由于空气吸力等类似情况引起的不良影响。
喷嘴列7被表示为设有相继排成一列的喷嘴开口4。但一个喷嘴列的喷嘴开口4也可相对运动方向9相互以一定的偏移来布置,其中,尤其是产生之字形的偏移。由此出现至少两个以列的格式布置的喷嘴列,这些喷嘴列就其喷嘴开口来说横向于运动方向9彼此偏移地、即有空缺地布置。
这种布置通过点条线13来表示,这种构型必要时作为对喷嘴列7的补充被证实是合乎目的的,以便通过细喷嘴开口用相应小尺寸的涂料滴进行基本上面的涂料涂敷。
此外图1表示:在边缘侧沿后部的纵向侧8可有利地设有另外的、尤其球形的间隔保持单元14。这些间隔保持单元能使装置1直接地在相对涂料涂敷面5的凸起上导行或沿这些凸起导行,例如由图2所示,其中,这种凸起在图2中由开关框架15表示。
为了使在这种相对涂料涂敷面5的凸起如开关框架15旁横向延伸的墙壁或类似物可实现紧邻接的涂料涂敷,设置在喷嘴列7中的喷嘴开口相对底部区3优选倾斜地布置,确切地向着纵向侧8的邻接的边缘6倾斜。
在图1中还概要地表示该装置优选地装有传感器16,这些传感器在底部区3中或在相对底部区3环绕的壳体边缘的区域中,以便在涂料涂敷面的不同地着色的区域或领域上实现清晰分界的涂料涂敷。这些区域或领域可通过预定的标记来相互分界,该标记由传感器16来检测,或通过传感器16来检测已着色的面的边界线,以便与此无间隙相邻地用例如另一色调的涂料涂敷来工作。这在图3中通过涂料涂敷面5的不同区域之间的边界线17来阐明。图中表示装置1覆盖着边界线17。
尤其在这种工作方面被证实有利的是,在考虑通过传感器16检测到的给定条件的情况下来触发控制以及必要时关闭相应的喷嘴开口,其中,这可单独地或成组地进行。
图1至3表示:装置1为了力图自给自足地工作优选被壳体包围地接收用于涂料涂敷的机构,其中,在壳体侧设有一个对组合的涂料存储容器供料的涂料注入接管18。合乎目的地还可组合过滤装置和/或搅拌装置,以便尤其在粘滞的分散涂料的情况下避免涂料结块及喷嘴开口的堵塞。装置1还设有手把20。
在所示的构型的范围中还有:在壳体2的其它边缘侧设置与间隔保持单元14类似的间隔保持单元,在本发明的范围中还有:喷嘴列的其它布置形式,其中通过相应喷嘴开口的相应打开及关闭也可实现与上述实施例不同的工作方向,这将扩宽根据本发明的装置的使用可能性。对于所有这些构型来说特别有利的还在于:通过由传感器装置对工作状态的相应检测能总是靠近到凸起及类似物的紧旁边工作,而不用担心污染凸起及类似物,以致可取消粘贴工作等以及在尽可能避免超出真正的涂料涂敷的工作的情况下进行快速及流畅的工作。
在根据本发明的装置的情况下,通过喷嘴开口4及对它们配置的喷嘴在涂料涂敷面5上以液滴形式进行涂料涂敷,近似于撞击涂料涂敷面5,在涂料涂敷面上涂敷的液滴“裂开”地交互流动,以致得到一个封闭的涂料膜。这由通过喷嘴的涂料滴的中断的、即脉冲式的撞击及涂料滴撞击时的相应压力引起。
图4及5概要地表示为此用于涂料涂敷的机构,例如它们可组合地设置在本装置中。
图4以概图表示喷嘴开口4,该喷嘴开口从喷嘴室21引出,该喷嘴室被控制喷嘴开口4的喷嘴针22穿过,该喷嘴针通过一个致动器23、如一个压电执行机构或类似机构可在往复方向上移动。致动器24由一个控制装置24控制,喷嘴室21与一个压力存储器25连接,为了建立所需的压力,对该压力存储器例如配置了泵26,通过该泵将待涂敷的涂料输送到压力存储器25中。
如果喷嘴针22由其所示的关闭喷嘴开口的关闭位置通过致动器23并抵抗弹簧34的力抬起,则与时间相关地产生涂料的喷出,这在相应的短的打开时间时产生涂料滴,该涂料滴根据压力存储器中具有的压力向着涂料涂敷面撞击。对此合乎目的的脉冲频率约为每秒钟100个涂料滴。
原则上用这种结构能够使喷嘴单个地动作、或在相应的致动装置的情况下也可成组地动作,其中为了操作多个喷嘴针,有时也可仅用一个共同的致动器23来工作。
在根据图4及5的构型中可优选地用一个共同的压力存储器25来工作,该压力存储器也可同时构成涂料储备容器。根据图5提出了一个机构,其中,相应的喷嘴开口4通过一个喷嘴针22来控制,根据喷嘴室21中的压力该喷嘴针可在闭合位置与打开位置之间移动。为此喷嘴室21可与一个泵缸的缸室连接,该缸室的活塞通过一个致动器加载。在图5中也示出一个通过泵26加载的压力存储器25,它与喷嘴室21用管路连接,其中在该管路连接部分中设有阀27。为了控制,也设有控制装置24,通过它来控制阀27。并且在该结构中,也可个别地或成组地控制这些喷嘴,以简单的方式这样进行,即,在到喷嘴室21的相应的连接部分28中设置一个单向阀27。
所述的机构仅代表可能的实施例,但也可以考虑其它的机构,如它们例如由计量***所公知。
