The disclosure relates to an operating method for a coating system, in particular for a painting system, for coating components (2), in particular motor vehicle body components (2), having the following steps: conveying, by means of a conveying device (3), the components (2) to be coated in a conveying direction through a coating booth (1), coating the components (2) in the coating booth (1) with a coating product by means of an application device (17-19) which applies a spray jet of the coating product, a portion of the applied coating product being deposited on the components (2) to be coated while another portion of the applied coating product floats into the interior of the coating booth (1) as an excess coating product mist (21), and reducing the excess coating product mist (21) from the interior of the booth by means in addition to or other than the downwardly directed air flow generated by a filter ceiling. In addition, the disclosure includes a correspondingly designed coating system.

A pile maintenance method, system, and apparatus including a shell configured to be opened and closed longitudinally such that the shell forms a chamber between a length of a pile and an inner surface of the shell when the shell is closed around the pile, at least one fixing member configured to fix the shell to the pile such that the shell is substantially centered on the pile, at least one sealing member provided proximate a bottom of the shell and configured to form a substantially watertight seal at a bottom of the chamber, a plurality of nozzles provided inside the shell and configured to spray one or more media onto the pile, and a drain outlet provided proximate the bottom of the shell and configured to drain contents from the chamber formed by the shell.

A multi reservoir dispenser includes a first reservoir for holding a first fluid and a second reservoir for holding a second fluid. The dispenser further includes first pump mechanism that includes a first displaceable plunger and a first plunger cavity that is disposed along a first flow path for receiving the first fluid and a second displaceable plunger and a second plunger cavity for receiving the second fluid. An actuator includes a selector and an actuator that are movable between: (a) a first position in which only the first plunger of the pump mechanism is actuated for discharging only the first fluid through a first orifice of a fluid dispensing manifold by causing the first fluid to flow along a first flow path; and (b) a second position in which only the second plunger of the pump mechanism is actuated for discharging only the second fluid through a second orifice of the fluid dispensing manifold by causing the second fluid to flow along a second flow path.

A liquid discharge head for controlling discharging of liquid, the liquid discharge head including a valve body configured to be movable, and to be pressed towards a discharge port from which the liquid is discharged; and a recessed portion provided in the valve body at a position facing the discharge port.

A multi-port dispensing device has a manifold with a top, a bottom, sides, and ends. An inlet conduit and a handle are connected to the manifold with the inlet conduit in communication with an inlet port in the manifold. A plurality of outlet conduits are connected to the manifold with each outlet conduit in communication with an outlet port in the manifold. A bottle or a nozzle are connected to the outlet ports. A shut-off valve on the bottle or outlet conduit permits and prevents flow from the manifold through the outlet conduits.

A multi reservoir dispenser includes a first reservoir for holding a first fluid and a second reservoir for holding a second fluid. The dispenser further includes first pump mechanism that includes a first displaceable plunger and a first plunger cavity that is disposed along a first flow path for receiving the first fluid and a second displaceable plunger and a second plunger cavity for receiving the second fluid. An actuator includes a selector and an actuator that are movable between: (a) a first position in which only the first plunger of the pump mechanism is actuated for discharging only the first fluid through a first orifice of a fluid dispensing manifold by causing the first fluid to flow along a first flow path; and (b) a second position in which only the second plunger of the pump mechanism is actuated for discharging only the second fluid through a second orifice of the fluid dispensing manifold by causing the second fluid to flow along a second flow path.

A sprayer system comprising: a first liquid line; a second liquid line; a liquid storage tank, which is in fluid communication with the first liquid line; an apparatus, which is in fluid communication with the second liquid line; at least one auxiliary tank in fluid communication with the apparatus; wherein the liquid storage tank is in fluid communication with the apparatus; and wherein the first liquid line and the second liquid line are in fluid communication with at least one row. The sprayer system can be used to apply one chemical to an entire field and selectively apply an additional chemical to individual locations in the field.

A system for applying a first coating composition and a second coating composition is provided herein. The system includes an atomizing applicator and a high transfer efficiency applicator defining a nozzle orifice. The system further includes a substrate assembly comprising a metal-containing substrate and a plastic-containing substrate. The metal-containing substrate is coupled to the plastic-containing substrate. The atomizing applicator is configured to apply the first coating composition to the metal-containing substrate. The high transfer efficiency applicator is configured to expel the second coating composition through the second nozzle orifice to the plastic-containing substrate.

An end effector for interfacing with a nozzle is disclosed. The end effector comprises a first end, which includes a receptacle. The end effector comprises one or more retention features positioned along a perimeter of the receptacle, where each of the one or more retention features is movable between a first position and a second position. Each of the one or more retention features is configured to lock the nozzle by securing onto a corresponding one of the one or more nozzle retention features in the first position, and to release the nozzle in the second position. The end effector may further comprise one or more actuators and a first channel, which includes a first inlet and a first outlet. A method of using an end effector to interface with a nozzle is also disclosed.
