An automated mobile sprayer (AMS) includes a mobile base, an applicator arm supported by the mobile base, and a nozzle extending from the applicator arm. The nozzle receives fluid from a fluid supply and generates an atomized fluid spray for application to a surface. The applicator arm moves vertically relative to the mobile base and the surface to cause the nozzle to generate a vertical fluid stripe. The mobile base moves laterally relative to the surface to cause the nozzle to generate a horizontal fluid stripe.

A force amplifying driver system including an actuator with a powered actuating member mounted for movement along a first distance X. A driven member mounted for movement along a second distance or working distance Y which is less than the first distance X. The powered actuating member is movable through a gap Z before being mechanically coupled with the driven member and subsequently moves with the driven member along the second distance Y. Energy is transferred from the powered actuating member to the driven member along the second or working distance Y. The force amplifying driver system may be used for actuating a fluid jetting dispenser.

The disclosure provides that the seal is not designed as an elastomer insert on the valve element.

The disclosure concerns a coating device for coating components with a coating agent, in particular for painting motor vehicle body components with a paint, with a printhead for applying the coating agent to the component, and with a coating agent supply for supplying the printhead with the coating agent to be applied, wherein the coating agent flows from the coating agent supply to the printhead at a specific coating agent pressure and a specific flow rate. The disclosure provides that the coating supply will control the coating agent pressure and/or the flow rate of the coating agent. Furthermore, the disclosure includes an associated operating method.

A system and method for controlling a needle motion of a material applicator are disclosed. The system includes an actuator assembly that contains a piezoelectric device, where the actuator assembly is connected to a needle and translates the needle along a vertical direction, and a sensor assembly that includes an emitter for emitting light, where a portion of the actuator assembly occludes a portion of the light. The sensor assembly also includes a receiver for receiving a non-occluded portion of the light and a sensor holder that secures the emitter and the receiver. The system further includes a controller in electrical communication with the piezoelectric device, emitter, and receiver, where the controller adjusts operation of the actuator assembly based on feedback received from the receiver.

A discharge device includes a nozzle (50) having a plurality of discharge ports, a liquid chamber (26) communicating with the plurality of discharge ports via a plurality of discharge flow paths, and a plunger rod (18) that reciprocates in the liquid chamber and is narrower than the liquid chamber. The plurality of discharge ports (62) is arranged un a straight nozzle arrangement line, and arranged with such a distance therebetween that globs of a liquid material having landed on an application target join together to form an application line. A plurality of liquid globs having been discharged from the plurality of discharge ports (62) have no contact with each other before landing on the application target, and letting the globs of the liquid material having landed join together on the application target.

A coating device comprises at least one application apparatus to discharge a coating agent from at least one coating agent nozzle. The application apparatus is configured to apply an oscillation to at least one of the coating agent and at least one coating agent jet such that at least one of the coating agent and the at least one coating agent jet break up into droplets.

A dispensing assembly comprising a cartridge holder is presented. The cartridge holder can receive a cartridge for dispensing a fluid. The cartridge can comprise a reservoir for receiving the fluid. The reservoir can comprise an outlet. The reservoir can have an adjustable volume for forcing the fluid through the outlet. The cartridge can further comprise a nozzle for dispensing the fluid. The nozzle can be connected to the outlet. The dispensing assembly can further comprise an actuator for actuating the adjustable volume. The dispensing assembly can further comprise an impulse generator for imparting an impulse to the nozzle. The impulse generator can comprise an actor for contacting the nozzle. The dispenser assembly can further comprise a controller for controlling the actor and the impulse generator.

An application device and an application method capable of increasing the speed of a line-drawing application are provided. The application device includes a discharge device, a worktable, a drive device, and a control unit. A discharge member gives an inertial force to a liquid material inside a liquid chamber, thereby discharging the liquid material from a plurality of discharge ports at the same time and forming a plurality of droplets on an application object. The plurality of discharge ports are arranged in a nozzle along a straight nozzle arrangement line, and the nozzle arrangement line is aligned with a drawing direction in which a drawing line is to be drawn. The application device performs the line-drawing application by discharging the liquid material such that a plurality of liquid masses discharged from the plurality of discharge ports do not contact with each other prior to landing on the application object, and that the liquid material having landed along the nozzle arrangement line join together on the application object.

The disclosure relates to an application device for applying an application medium onto a component, preferably for application of a coating onto a motor vehicle body component. The application device includes a print head for preferably serial and/or permanent application of the application medium, wherein the print head has: a nozzle plate, at least one nozzle in the nozzle plate in order to discharge the application medium, at least one valve element, which is movable relative to the nozzle plate, for control of the application medium discharge through the at least one nozzle, wherein the at least one movable valve element closes the at least one nozzle in a closing position and releases it in an opening position, and at least one drive for moving the at least one valve element.
