A method includes rotating a substrate, supplying a first processing liquid from a first nozzle to the substrate during a first period, and supplying a second processing liquid from a second nozzle to the substrate during a second period. First and second liquid columns are formed by the first and second processing liquids during at least partially overlapped period of the first and second periods, respectively. The shapes and arrangements of the first and second liquid columns satisfy that: at least one of first and second central axis lines of the first and second liquid columns is inclined with respect to a rotational axis line of the substrate, first and second cut surfaces obtained by cutting the first and second liquid columns along a horizontal plane at least partially overlap each other, and any point on the first central axis line is located on the second central axis line.

A treatment system for spraying treatment fluid onto plants in a field is described. The treatment system includes a configurable treatment mechanism including an array of nozzles and valve assemblies coupled into manifolds, and manifold assemblies. The nozzle comprises a nozzle housing and an insert assembly contained within the nozzle housing. When coupled, a top casing including a fluid inlet and a bottom casing including at least one fluid outlet form the nozzle housing. The insert assembly comprises at least one nozzle insert to fluidically couple the fluid inlet and the fluid outlets such that fluid entering from the fluid inlet exits the nozzle housing through the fluid outlets.

A next generation painting robot with advanced fluid delivery system, enhanced kinematics and a service airlock compartment. The painting robot includes a fluid delivery system which places color changing valves and pumping hardware on the back side of the robot's mounting pedestal, where it can be serviced without a technician having to enter the spray booth. The fluid delivery system also allows smaller and lighter robot arms, and is designed to minimize paint waste and wait time during color changes. The robot also features kinematics providing redundant inner arm rotation. The arm kinematics, along with the smaller arms, a paint supply line routed through the center of first and third arm joints, and optimized motor conductor routing, dramatically improve near reach flexibility. The improved near reach flexibility in turn allows a smaller spray booth than possible with previous robot architectures.

A wafer processing apparatus includes a rotating chuck which is rotatably installed inside a cup housing and on which a substrate is mounted, a nozzle table rotatably installed inside the rotating chuck, a guide installed inside the nozzle table, a moving module movably installed on the guide, a guide arm configured to support a fluid supply line part, a lower nozzle part coupled to the guide arm to move together with the moving module and connected to the fluid supply line part, a driving shaft part connected to the rotating chuck and the nozzle table to rotate the rotating chuck and the nozzle table, a moving shaft rotatably installed inside the driving shaft part and connected to the moving module to move the moving module, and a driver connected to the driving shaft part and the moving shaft.

There is provided a nozzle of a cleaner device that cleans an object to be cleaned having a convex surface. The nozzle comprises: a spray orifice that is positioned outside the convex surface and from which a fan-shaped layer of a cleaning fluid is sprayed onto the convex surface. The spray orifice is shaped such that the sprayed fan-shaped layer of the cleaning fluid is convexly curved toward the same direction as the convex surface.

A spray nozzle body has an upper end provided with a clamp arrangement comprising upper and lower clamp halves tightly clamped onto a fluid supply tube having a preselected first diameter. A removable tubular fluid delivery stem is received in a receiver hole extending vertically into the nozzle body from a clamping surface of the lower clamp half and has an upper end portion tightly received in a fluid outlet hole, of preselected size, provided in the supply tube. The clamp arrangement may be reconfigured for being clamped onto a smaller fluid supply tube by providing a replacement upper clamp half and a pipe-size adapter, each having appropriately sized clamping surfaces, with the adapter being seated within the clamping surface of the lower clamp half. The pipe-size adapter incorporates a suitably dimensioned fluid delivery stem.

A vertical internal coating machine is taught, which may be used with bodies such as cans (2 piece, 3 piece, draw, redraw) and including cylinders, containers and any similar body. In the machine cans or similar bodies are sprayed with the star wheel in continuous motion without stopping and starting. The machine teaches that a plurality of spray guns may be provided for each pocket of the star wheel. By means of the machine an improved line layout is devised which may eliminate the need to raise the bodies immediately prior to a necker by allowing the vertical can internal coating machine and internal bake oven to be disposed on any level of the facility, upper, lower, mezzanine, etc. In green aspects, the machine may use negative pressure cabinets/hoods and positive pressure tunnels to entrain volatile organic chemicals emitted by the spray guns and coated bodies and may send these VOCs to a VOC destruction device, such as an oven.

A shaping guide of at least one pipe for feeding a fluid product into a spraying element belonging to a sprayer of coating product is configured for being mounted around a central body of the sprayer and includes at least one spiral-shaped retaining portion for retaining in position a section of the feeding pipe, with a predetermined geometry, configured for providing electrical insulation between a mouth and an outlet of the feeding pipe. Each retaining portion has, in cross-section, a concave inner shape configured for surrounding the pipe section over more than half of the circumference thereof, preferentially, a shape in the form of an arc of a circle or U-shaped, which extends over an angular sector with an angle at the apex greater than or equal to 185°.
