Abstract:
This station (10) comprises at least two areas (11, 12) for cleaning/filling a reservoir, each adapted to receive a sub-assembly (7) formed by a reservoir (8) and a sprayer (9) while this sub-assembly (7) is disconnected from the robot. Means (51, 52) for cleaning and/or filling the reservoir and/or the sprayer in each of these areas are provided, while these areas (11, 12) are adapted to be brought (F2, F3) into a position of connection of a sub-assembly (7), disposed in one (11) of them with the cleaning and/or filling means (51, 52). The process consists, inter alia, in positioning (F6) a coating product supply unit (52), in a position of connection with the first sub-assembly (7) received in an area (11) of the station (10) of cleaning/filling.
Abstract:
A pressure sprayer is pressurized automatically with movement of the sprayer and maintains adequate pressure during non-movement to allow the ejection of an amount of liquid before needing re-pressurization. The pressure sprayer includes wheels that allow the pressure sprayer to be mobile. A cam is attached to the axle of the wheels which rotates with the rotation of the axle/wheels. A pressure pump is associated with the cam such that movement of the cam causes the pressure pump to pump liquid from a holding tank to an accumulator or directly to a spray wand in communication with the pump. The liquid may be sprayed (ejected) from the accumulator during both movement (pumping) and non-movement (no pumping) of the sprayer, while the liquid may be directly sprayed from the holding tank only during movement (pumping) thereof. Thus, as the wheels rotate due to moving the pressure sprayer, the cam causes movement of the pressure pump to fill the accumulator with the liquid under pressure. The pressure pump is adapted to obtain liquid from the holding tank and provide that liquid to the pressure accumulator. A relief valve is provided to relieve the buildup of pressure during movement of the wheels when no spraying is taking place.
Abstract:
An apparatus imparts movement to a fluid dispersing nozzle with a mechanism for converting rotational movement about an axis of rotation into orbital movement about the axis of rotation, and an elongate member is connectable to the mechanism at one end and is connectable to a fluid nozzle at an opposite end from the mechanism. The orbital member provides orbiting movement of the opposite end in response to rotation of the mechanism about the rotational axis, and provides stationary centered positioning of the opposite end in response to a non-rotating mechanism. A speed multiplier transmission or gearbox can be provided between the motor shaft and drive spindle if desired. A separate mixer is positionable within the member and is moveable longitudinally with respect to the member during use. The mixer includes a valve member connected to one end for movement relative to a valve seat defined by an inner surface of the cone.
