Abstract: An arrangement is disclosed for the preferably automatic coating of objects with a coating material, in particular coating powder. The arrangement includes at least one spray device having a spray nozzle via which the coating material is dispensable in a main spraying direction. An extension is further provided, wherein an end region of the extension facing the spray device is preferably detachably connected to an end region of the spray device associated with the extension opposite from the spray nozzle. The arrangement further includes a preferably horizontally extending guide via which the extension with the spray device connected thereto can be longitudinally moved in the direction of extension of the guide relative to the object to be coated. The main spraying direction of the spray nozzle may be implemented so as to deviate from the direction of extension of the guide by a predefined or definable angle.

Abstract: A powder-dispensing device in the form of a dense-phase powder pump or of a powder injector is provided to deliver coating powder from a powder reservoir to a powder-spraying device. To make the spray coating operation easier for the customer and to be able to make it more cost-effective, without having to compromise on good coating quality and good coating efficiency, a control device is integrated in the powder-dispensing device or is connected, in particular directly, to the powder-dispensing device and is designed to establish at least one parameter that is characteristic of a spray coating procedure carried out with the powder-coating device.

Abstract: Disclosed herein is a powder container for supplying coating powder to a powder coating station. The powder container includes a powder compartment for coating powder, the powder compartment being delimited by side walls, one of which is provided with an outlet port via which the powder compartment is or can be fluidically connected to an inlet of a powder deposition system. The effective flow cross-section of the fluid connection between the outlet port and the inlet of the powder deposition system can be variably adjusted.

Abstract: An installation is disclosed for coating objects, preferably automatically, with coating material, the installation having a coating station with at least one coating gun for spraying coating material, in particular as required, in the direction of a coating region, and having a conveying apparatus, by means of which objects to be coated can be transported, in particular continuously, through the coating region. Provision is made, in particular, for the installation to have a device for detecting the presence and/or absence, in a monitoring region located upstream of the coating station—as seen in the conveying direction of the conveying apparatus—of an object to be coated, wherein there is also provided a control device, which is designed to activate the at least one coating gun of the coating station in dependence on the detection result of the device for detecting the presence and/or absence of an object to be coated.

Abstract: The invention relates to a control circuit for protecting an electrostatic spray-coating apparatus, which has a high-voltage supply, against spark discharge. The control circuit has a disconnection device for automatically disconnecting the high-voltage supply, and has a device for detecting abnormal operation of the high-voltage supply. The device for detecting abnormal operation of the high-voltage supply is designed to monitor at least one parameter which is characteristic of the operation of the high-voltage supply, and to output a corresponding disconnection signal to the disconnection device when the at least one parameter which is characteristic of the operation of the high-voltage supply exceeds or falls below a predefined or predefinable limit value.
