Handling device, workpiece treatment device and method for detecting the presence or the state or the detachment of a workpiece

In order to create a handling device for a workpiece, for example a conveying device for vehicle bodies, by means of which the workpiece is able to be handled safely and reliably, it is proposed that the handling device comprises the following: a moving device for moving and/or conveying the workpiece; a workpiece holding device for detachably securing the workpiece to the moving device; a detection device for carrying out a detection operation by means of which the presence of a workpiece arranged on the workpiece holder and/or a state of a workpiece arranged on the workpiece holding device and/or the detachment of a workpiece from the workpiece holding device is able to be determined. 为了提供种用于工件的操作装置，例如用于汽车车身的输送装置，通过该操作装置能够安全可靠地操作工件，建议该操作装置包括：用于移动和/或输送工件的移动装置；用于将工件可拆卸地固定在移动装置上的工件接纳装置；用于执行检测过程的检测装置，通过该检测过程能够检测设置在工件接纳装置上的工件的存在和/或设置在工件接纳装置上的工件的状态和/或工件从工件接纳装置上的脱落。
