Description

用于气动涂漆的自动设备
技术领域
本发明涉及旋转钟形件(rotary-bell)空气喷漆设备,其为工业涂漆的设施中所使用的类型。
具体地,该设备应用于利用连续生产载流体的设备的自动涂漆系统,载流体从压缩环境空气开始获得。
背景技术
已知在自动涂漆系统中,使用自动化臂,该自动化臂在端部承载用于空气喷漆的操作头,操作头由空气枪或者传统型或静电型的旋转钟形件装置组成。在第一种情况下,系统将用于雾化漆的载流体流以及用于形成漆扇或成形空气的第二载流体流送至枪。
在旋转钟形件的情况下,系统将中心漆流、用于钟形件的旋转的第一受压流体流、用于雾化和混入漆的第二周向受压载流体流送至涂漆头,并因此形成漆锥或成形空气。
目前,在雾化漆的自动工业系统中,通常用作推进载流体的是压力总体不低于3-6barG的压缩空气。
然而,已知类型的自动化自动涂漆系统对漆锥或漆扇(成形空气)的控制并不令人满意,且具有过喷(overspray)的现象,即未到达待涂漆基底而分散于涂漆周围环境的漆的损失。
另一缺陷为,为了压缩载流体并获得雾化漆冲击待涂漆基底的足够的高速,必须使用相对高的压力。
发明目的
因此,本发明的第一目的为一种如下设备,该设备将不具有已知系统的前述缺陷,该设备将能增加成形空气的密度从而更有效地雾化漆,并能同时减少雾化所需的载流体的压力。
发明内容
上述和进一步的目的可通过根据所附一项或更多项权利要求的设备实现。
本发明的第一优势在于雾化漆的密度大于已知类型的系统所获得的密度,使基底的涂层在覆盖能力、涂漆速率、沉积在基底上的漆层的抓力方面能够大幅提升。另一优势为该系统使漆转移至待涂漆物品上的效率能够增高,由于压力的减少和更高的密度使得过喷显著地减少。另一优势为,由于载体的更高的密度,该系统使钟形件能够接近待涂漆物品以获得更好的厚度均匀性,并在此情况下还减少过喷效应,并且在静电旋转钟形件的情况下减少静电力。
另一优势为减少应用的喷涂次数,并以单涂层获得相同的厚度,从而在例如为车身、车组件或其它类似物品涂漆的自动化系统中显著地减少循环次数。
附图说明
由之后的单纯通过非限制性示例提供的说明和附图,上述优点和进一步的优点可被本领域技术人员更好地理解,其中:
图1是根据本发明的设备的示意图。
图2是图1中设备的俯视图。
图3示出了承载雾化装置的自动涂漆臂。
图4示出了承载旋转钟形件装置的自动涂漆臂。
图5示出了已知类型的旋转钟形件空气涂漆装置的示例。
具体实施方式
参考附图,描述了如下类型的自动空气喷漆设备,该类型设备包括用于生产受压的载流体流的模块17,该载流体流从压缩空气源1开始获得,并被传送至至少一个自动涂漆设备2,自动涂漆设备2装备有自动化臂3,自动化臂3设置有用于空气喷漆的操作头30,该操作头30具有漆的出口4以及受压流体流的至少一个第二出口5,第二出口5设在所述第一出口周围,用以形成漆锥或漆扇。
在图3和图4中示意性表示的装置2还包括管6和管7,管6用于从漆源至出口4的漆流供给,管7用于供给雾化所述漆流的受压载流体流。管7可与另一管8一致或不一致,管8用于被传送至第二出口5的受压载流体流的供给。
根据本发明,模块17为由受压环境空气源1供给的中空纤维分离模块,用于连续生产由优选为98%至99.9%的高纯度氮组成的载流体流,且包括用于调节所生产的氮的压力的装置19、25、26以及用于对氮流进行热调节的装置18、9,氮的压力调节为0.5与4bar之间,优选地为0.5与1.5bar之间,氮流的温度可调节至8℃与80℃之间,优选地为8℃与22℃之间。
根据本发明的另一个有利的特征,设备还包括可调节的受热管29,该受热管用于离开分离模块17的氮流的热稳定。
在运行中,模块17连接至控制单元50,控制单元50管理设备的自动运行,具体管理装置2的运动和运行周期,并使得能够设置用于生产载流体的参数(纯度、温度、压力)以及涂漆参数(速度、位移、喷涂次数)。
有利地,通过该方案,雾化漆的密度大幅增加,由于氮的比重更高,因而氮可以相对低的压力以及基于涂漆环境状况和待涂漆的基底类型所调整的温度送至管7。
在优选实施例中,设备包括离子化单元28,该离子化单元本身是已知的,能够离子化带有正电荷或负电荷的、或处于中性等离子态的氮流。
图3示出的是涂漆装置,该涂漆装置中的操作头为旋转钟形装置(根据图5的本身已知的类型),包括旋转钟形件10,由受压流体流所驱动的气动马达而导致旋转钟形件10旋转,受压流体流由管14供给,受压流体流可与用作载流体的流体一致或不一致。
钟形件10设置于臂3的一端部11,并设置在中心,且带有与供漆管6连通的漆出口4,用于实现漆流向钟形件边缘的离心散射。操作头30还包括设置于钟形件上游的环12,环12设有氮出口5,氮出口5沿涂漆方向X朝向钟形件,且与供给用于雾化的氮流的所述管7连通,在这种情况下该氮流还实现了形成漆锥13的功能。
图4中示出的涂漆装置中,上述操作头为空气喷漆枪,空气喷漆枪包括漆出口4,漆出口4设置于臂3的端部11且与供漆管6以及供给用于雾化的氮流的管7连通。在这种情况下,漆流和用于雾化的氮流以本身已知的方式在出口4上游的点31处会聚,该方式不作进一步描述。
操作头30还具有至少两个侧氮出口5,侧氮出口5与管8连通,管8供给用于形成漆扇16的氮流。
参考图1和图2,描述了用于生产载流体的模块17的优选实施例,其设想了第一中空纤维分离膜20,第一中空纤维分离膜20由压缩空气源1供给,压缩空气源1设有过滤器33,并在出口处与储存氮(或富氮的改进空气)的第一容器21连通,第一容器21又在出口处与第二中空纤维分离膜22连通,第二中空纤维分离膜22将高纯度氮送至存储受压氮的第二容器23。
在所描述的示例中,热调节装置包括冷却和/或加热组件18,组件18优选地通过绝热管32接收离开容器23的氮流,且能够将氮流的温度稳定在可在8℃与80℃之间调整的值上。
热调节装置还可包括:设置于通向第一膜20的入口处的加热器26,其能够将空气加热至10℃与60℃之间的温度;以及外加热器9,其用于至少加热膜20,膜20也在10℃与60℃之间的温度范围内起作用。
再一次在所示的优选示例中,用于调节压力的装置为设置在压缩空气源1下游的压力调节器19、紧接地设置在膜20和22中的一个或两个的下游的调流阀24以及紧接地设置在容器21和23中的一个或两个的下游的背压调节阀或背压调节器(BPR)25。
优选地,来自供应源1的压缩空气在进入膜20之前连续穿过压力调节器26、电磁阀34、用于将流分化的渐进致动器35以及加热器26。有利地,借助该方案,由于对压力和温度的控制以及防止立刻将全部压缩空气流引入膜的渐进致动器35,在可调节的最佳条件下,将压缩空气送入膜还发生在操作的开始。
在某些应用示例中,发现借助以下所示参数可获得极好的涂漆成果。
示例1
在温度为20℃的环境中对塑料涂漆
-纯度为99.5%
-压力为2bar
-温度为18℃
-正离子化
示例2
金属基底
-纯度为99%
-压力为1.8bar
-温度为18℃
-负离子化
已根据优选实施例描述了本发明,但等同的变型是可设想的,不会由此离开本发明的保护范围。

说明或声明(按照条约第19条的修改)
根据按照PCT第19条的修改后的权利要求,申请人指出修改后的权利要求克服了审查员所提出的异议。
申请人进一步提出,由于以下原因,权利要求1还满足了专利性的要求。
新颖性
US20100298069描述了用于将表面涂层施加于高尔夫球的涂漆设备,其中未提及受压氮的使用是用作送雾化流或雾化漆以及将涂漆空气锥成形。
权利要求1和16因此相对于US20100298069具备新颖性。
相对于其它ISR所引用的现有技术文件,可适用相同的考虑。
创造性
本发明面对并解决了技术问题:提供能够增加成形流体流的密度的设备,从而改善雾化漆的工艺,因而使所需的输送压力减少。
即新的权利要求1,以及从属权利要求2-15和权利要求16相对所引用的现有技术是具备专利性的。
申请人按照PCT第19条修改了权利要求书。其中,对权利要求1和16进行了进一步的限定。具体修改可见所附修改草稿。其它权利要求没有改变。
