The invention relates to a method for providing a spray gun (1) in a washing space (2) in a spray gun washing device (3), said spray gun comprising a paint passage (7) with a paint inlet (8). The washing space (2) comprises at least one cleaning nozzle (4) and an attachment surface (10). The cleaning nozzle (4) communicates with a cleaning medium system (5). The attachment surface (10) in the washing space (2) is configured to receive a spray gun (1) with a spray gun holder (9) since the position of the spray gun in the washing space is variable depending on the position of a paint inlet (8) of the spray gun relative to the position of the cleaning nozzle (4) in the washing space. The invention also relates to a spray gun washing device (3) comprising said characterizing features for cleaning the spray gun (1) which during cleaning is provided in said spray gun holder (9).

A dispenser machine includes a dispenser device with a valve assembly. The valve assembly includes at least one distribution duct, at least one distribution nozzle connected to a second end of the distribution duct, at least one first shutter, and at least one valve body, operationally interposed along the distribution duct. The valve assembly includes a closing device for closing the nozzle. The closing device has at least one obstructing element acting upon an aperture of the nozzle for selectively opening or closing the nozzle, and a mechanical connector for connecting the obstructing element to the first shutter, so that switching the shutter will cause the obstructing element to be switched. The shutter is adapted to translate within the valve body between first and second configurations, causing the corresponding obstructing element to switch, respectively, between the closed condition and the open condition.

An apparatus for preventing a cover from being drawn into a joint of a paint robot includes a circular ring member mounted to the paint robot proximate the joint. The circular ring member may include first and second blocking members. The paint robot includes first and second portions rotatable relative to one another about an axis of the joint. The circular ring member circumferentially surrounds the first portion of the paint robot such that the axis of the joint passes through the circular ring member.

The method can include: sampling measurements of a vehicle in-situ, generating a model based on the measurements, and determining a wash path based on the model. The method can optionally include washing the vehicle according to the wash path.

The invention relates to a shower arm with a torus regulator and a magnetic ring that is comprised of a body (1) with a body head (25), a bell (2), a cover (3), a torus (4), a mixing element (5), a ring (6), a pin (7) and a barrier (9) on the cover, a barrier (8) and a nozzle (10) on the bell, a cavity (11) for water inlet, an inlet (12) of water into the shower head (25), a space (13), a gap (14) on the mixing element, a chamber (15), gaskets (16) and (17), a thread (18), a space (19) for directed flow, pins (20) and a groove (21) on the ring, a groove (22) on the bell, a thread (23) for connecting a hose, a support surface (24) a magnetic ring (26) and an output spray (27) of water and air. When the water circulates within the space (19) underneath the torus (4), negative pressure—vacuum occurs from both the internal and the external sides of the torus cross-section that conditions suction of the air from the chamber (15) of the cone of the bell (2). This air is suctioned through the nozzle (10). In the space below the mixing element (5) the air and the water swirl which alternately enter into the air/water mixture and form a wide conical spray (27). The bell is provided with the groove (22), into which the ring (6) with pins (20) is tightly inserted. The pins are made from a soft material and serve for mechanical massage of the skin and the crown of the hair. On the other side in the ring there is the groove (21), into which the magnetic ring (26) is inserted. Its role is to normalize the water crystals and to arrange them into a natural shape. The nozzle (10) for spray outlet has an orifice large enough in order not to clog due to impurities in the water and limescale.

The present disclosure provides a nozzle cleaning device, a doctor blade replacing apparatus and a doctor blade replacing method. The doctor blade replacing apparatus includes a first doctor blade box, a second doctor blade box, a transferring assembly and a clamping and conveying mechanism. The transferring assembly includes a first tray which is disposed between the first doctor blade box and the second doctor blade box and a pushing assembly which is configured to push the first doctor blade in the first doctor blade box to the first tray and push the second doctor blade on the first tray into the second doctor blade box. The clamping and conveying mechanism is disposed between the first tray and the nozzle cleaning device for clamping and conveying the first doctor blade and the second doctor blade between the first tray and the nozzle cleaning device.

The disclosure relates to a painting system component, in particular a rotating bell (1) for a rotating atomizer, including a main body (1) and a surface coat (8) at least on a part of the surface of the main body (1). The surface coat (8) reduces the tendency of the painting system component to become dirty and/or improves the ease of cleaning of the painting system component.
