Abstract: A device for automatic spray application of paint through a spray nozzle comprises a container containing paint, arranged in the immediate proximity of the spray nozzle and connected to the spray nozzle through a conduit for supply of paint to the nozzle for spray application. The container is arranged rotatably, and the device comprises members adapted to drive the container to rotate for pressing paint contained therein outwardly towards a peripheral region of the container. The conduit has an opening in this region. An overpressure of a pressurized medium in the container for pressing paint out through the opening to the spray nozzle is provided.

Abstract: A device is disclosed for the automatic spray application of paint. The device has a paint container and a spray nozzle arranged in close connection and adapted to provide paint from the container to the spray nozzle during the spray application. A dosing apparatus regulates the compression of an external surface against the inner volume of the paint container and thereby forces paint out of the container and into the spray nozzle through an opening of the container. A number of receiving members are adapted to receive and hold the paint container close to the spray nozzle, such that the paint container is detachable and removable from the device when replacing a paint container. The paint container has an elongated feeding tube, at its opening, that is held by the receiving members when the tube is inserted in the nozzle.

Abstract: In a plant for automatic spray application of paint through a spray nozzle (12), two parallel lines (9,10) each lead from an associated arrangement (1,2) for supplying paint to the spray nozzle. After paint has been fed through one of the lines to the spray nozzle followed by closing of a valve means (15,16) associated therewith for changing the arrangement (1, 2) supplying paint, a device (24) is adapted to feed such a volume of fluid into this line upstream of the valve means, with respect to the paint feeding direction, in the reverse direction so that the paint present in the line is pushed back into the arrangement without the fluid reaching it.

Abstract: A device for feeding a controlled volume flow of liquid to a spray nozzle for automatic spray application. A conduit defines a flow path from a liquid source to the spray nozzle. A displacement pump type member is arranged in the conduit. A driver drives the displacement pump type member with the movable parts thereof with a speed determined by the actual volume flow through the conduit. Elements arranged in the conduit upstream of the displacement pump type member supply the flow of liquid through the conduit to the displacement pump type member and properly feed the liquid in the conduit. A valve is located in the conduit. A regulator regulates the volume flow through the conduit by regulating the throttling degree of the valve means. A first measurer measures the pressure of the flow in the conduit downstream of the displacement pump type member. A second measurer measures the pressure of the flow in the conduit upstream of the displacement pump type member.

Abstract: A paint supply system for a painting robot, the system includes a paint spraying device mounted on a tool holder at the outer end of a robot arm and having an adapter unit for mounting on the robot arm close to or in direct contact with the paint spraying device, first and second supply lines for supplying first and second painting fluids to the adapter, and a third supply line for supplying a cleansing fluid to the adapter. The adapter includes a first inlet duct connected to the first supply line, a second inlet duct connected to the second supply line, a third inlet duct connected to the third supply line, an outlet duct connected to the paint spraying device, first valve means for connecting the first inlet duct to the outlet duct, second valve means for connecting the second inlet duct to the outlet duct, and third valve means for connecting the third inlet duct to the outlet duct.
