Description

带有提高的安全性和降低的故障概率的轨道式焊接装置
技术领域
本发明涉及一种轨道式焊接装置(Orbitalschweiβvorrichtung)。这种轨道式焊接装置例如在文件DE 20 2014 100 284 U1中展示。
背景技术
在文件US 6,380,505 B1中描述了一种焊接装置，且附带地提及到，代替延长轴可使用可调整的滑动离合器(Rutschkupplung)，以为了提高使用者安全性且防止损害。
发明内容
但是发明人认为值得改进的是，提高安全性且降低故障概率。本发明的任务是，执行这种改进。该任务通过独立权利要求解决。有利的改进方案在从属权利要求中限定。
尤其地，该任务通过一种轨道式焊接装置解决，该轨道式焊接装置带有焊接头，所述焊接头具有管安装件(Rohrhalterung)和相对于所述管安装件可转动地支承的焊接电极保持器(Schweiβelektrodenhalter)，所述轨道式焊接装置具有通过所述轨道式焊接装置的马达控制器操控的电马达，该电马达被配置成驱动所述焊接电极保持器且因此使所述焊接电极保持器相对于所述管安装件转动，其中所述轨道式焊接装置具有电气转矩测量设备，该转矩测量设备配置成，优选地每当所述马达被激活、即被供应有驱动电流时，测量由所述马达施加到所述焊接电极保持器上的转矩，其中所述转矩测量设备与所述马达控制器连接，且其中所述马达控制器配置成，当所述转矩超过预定的第一转矩时，自动地使所述马达停住。
该任务此外尤其通过用于运行轨道式焊接装置的方法来达成，该方法包含步骤：
-通过由所述轨道式焊接装置的马达控制器操控电马达，使所述轨道式焊接装置的焊接电极保持器相对于所述轨道式焊接装置的管安装件转动，
-优选地每当所述马达激活、即被供应有驱动电流时，借助于电气转矩测量设备测量由所述马达施加到所述焊接电极保持器上的转矩，
-当所述转矩超过预定的第一转矩时，通过所述马达控制器自动地使所述马达停住。
由此进一步提高安全性且降低由于通过异物堵塞驱动机构引起的装置出故障的概率。与带有滑动离合器的实施方案相比，根据本发明使所述马达停住。滑动离合器最多地限制力矩且在此所述马达然后还一直将限制的力矩施加到所述驱动机构上。
所述预定的第一转矩优选地存储在所述轨道式焊接装置中。所述预定的第一转矩大于使轨道式焊接头正确发挥功能所必要的转矩，且代表所述焊接电极保持器或在马达和焊接电极保持器之间的驱动机构被堵塞。
马达控制器优选地被理解为一个或多个电气设备，所述电气设备配置成直接或间接影响所述马达的运行状态(例如转速、转矩)。
在本发明的另一实施例中，所述转矩测量设备具有电流测量设备，该电流测量设备配置成，测量用于驱动所述马达的电马达电流作为代表所述转矩的值。在根据本发明的另一方法中，所述电气转矩测量设备借助于电流测量设备测量用于驱动所述马达的电马达电流作为代表所述转矩的值。
由此借助于电流传感器实现简单地测量与所述转矩近似成比例的信号。所述电流测量设备优选为在所述马达的电流馈送线中的电阻，优选是低电阻的。
在本发明的另一示例实施例中，所述马达控制器配置成，一旦所述马达由于超过所述预定的第一转矩而停住，则在相反方向上以规定的时间或规定的转数启动所述马达。在根据本发明的另一方法中，一旦所述马达由于超过所述预定的第一转矩而停住，则通过所述马达控制器使所述马达以规定的时间或规定的转数在相反方向上自动地启动。
由此还进一步提高安全性。如果人的手指夹在驱动机构中，则手指通过上述反向运行可被再次释放。
在本发明的另一示例实施例中，所述马达控制器配置成，一旦所述马达由于超过所述预定的第一转矩停住而导致所述马达在相反方向上以规定的时间和规定的转数被启动，在这之后，如果所述转矩再次超过所述预定的转矩，自动地再次使所述马达停住。在根据本发明的另一方法中，一旦所述马达由于超过所述预定的第一转矩停住而导致所述马达在相反方向上以规定的时间或规定的转数被启动，在这之后，如果所述转矩再次超过所述预定的转矩时，通过所述马达控制器再次使所述马达停住。
由此还进一步降低安全性和由于通过异物阻塞所述驱动机构引起的装置出故障的概率。如果在反向运行时可能出现重新的阻塞(＝转矩超过所述预定的第一转矩)，则再次使所述马达停住。
在本发明的另一实施例中，所述轨道式焊接装置配置成，如果所述转矩在预定的时间段内持续地超过预定的第二转矩，自动地输出视觉和/或听觉和/或触觉信号或发送电子信号以用于在另一器件上视觉和/或听觉和/或触觉展示或将电子信号存储在存储单元上，其中所述预定的第二转矩小于所述预定的第一转矩。在根据本发明的另一方法中，当所述转矩在预定的时间段内持续地超过预定的第二转矩时，所述轨道式焊接装置自动地输出视觉和/或听觉和/或触觉信号或，所述轨道式焊接装置自动发送或存储电子信号以用于在另一器件上视觉和/或听觉和/或触觉展示，其中所述预定的第二转矩小于所述预定的第一转矩。
由此实现磨损探测。如果转动机构例如由于脏物或润滑介质干掉而可能渐渐地变得越来越迟缓，这可以此确认。要么直接给予使用者视觉和/或听觉和/或触觉信号，要么将信号例如发送到中央监视设施(例如建筑公司的总部)，以在那里输出视觉和/或听觉和/或触觉信号，要么将所述信号存储在存储单元、例如所述轨道式焊接装置的存储芯片上，以为了然后例如由维修技术人员读出，然后借助于视觉和/或听觉和/或触觉信号给该维修技术人员展示关于出现的磨损情况的信息。
在本发明的另一示例实施例中，所述马达控制器和所述转矩测量设备布置在所述轨道式焊接装置的焊接电源中，而所述马达布置在所述焊接头中。由此所述焊接头可包含易于处理的(handlich)尺寸。
附图说明
现在应按照附图示例性地进一步展示本发明。
