A carrying device includes a swivel that swivels around a central axis line of a revolution orbit that passes through a workpiece transfer area and a workpiece work area for a workpiece to be worked on by a robot, multiple workpiece holders positioned on the swivel such that when a first one of the workpiece holders is positioned in the workpiece transfer area, a second one of the workpiece holders is positioned in the workpiece work area, a revolution driver that causes the swivel to swivel around the central axis line of the revolution orbit, and a tilting driver that tilts each of the workpiece holders with respect to the central axis line of the revolution orbit.

A system for analysing drops capable of being ejected by a coating product applicator, includes a light source configured to illuminate a drop ejection zone, designated observation zone; a first image acquisition device configured to acquire an image of the observation zone; and an image analyser configured to determine, from the image of the observation zone, the presence of drops at a given distance from the applicator, the size of the drops and the absence of satellite; the light source and the first image acquisition device being situated on a same side of the observation zone.

Provided is a projection screen. The projection screen includes a first transparent cover plate, a transparent touch panel, and a first nanoparticle layer, wherein the first nanoparticle layer and the first transparent cover plate are sequentially laminated on one side of the transparent touch panel, and the first nanoparticle layer comprises a plurality of dispersed nanoparticles of different particle sizes. A method for manufacturing a projection screen, a projection display system, and a projection display method are also provided.

An applicator and method of use is disclosed for applying coatings and paints to various surfaces. As shown, the sprayer may have an undercarriage frame that supports three-wheels. All three wheels may run parallel with the first wheels and second wheels attached to the sprayer frame via an undercarriage with the third wheel positioned behind and between both the first and second wheels on a separate arm or frame. The width of the sprayer booms may be adjusted. The undercarriage may be folded entirely or only a portion therein. The arm of the third wheel may be folded or telescope, as required by a particular application. A handle, which may be adjustable, may be positioned between the sprayer frame and the undercarriage. Use of the applicator according to the method discussed herein reduces operator fall exposure and increases application efficiency.

The invention relates to a work vehicle (1) comprising an operable arm (10) adapted to handle a tool (A-D) fastened to the free end of the arm, a control unit (4) for controlling the work vehicle (1), a dust control system arranged to distribute water mist with the aim of retaining dust that is created when the tool is used. For efficient dust control, the dust control system comprises a pressure air source (31) and a water pressure source (21), an air duct (33) arranged for the tool (A-D), through which an airflow from the pressure air source (31) can be conveyed, an injection nozzle (26) directed against the airflow in the air duct (33), with which water from the water pressure source (21) can be sprayed into the airflow for atomization of the water into liquid drops, which together with the airflow form a water mist, whereby the air duct arranged for the tool (A-D) is directed, so that the liquid drops form water mist (36) in the surroundings of the tool.

A robotic apparatus for painting a workpiece includes a redundant axis robot for use in a robotic painting system. The redundant axis of rotation provides the robot arm additional flexibility in avoiding obstacles and reaching an interior of the workpiece to apply paint thereto. The robotic apparatus could be a seven-axis robot arm or a five-axis parallel link panel opener robot arm for opening and/or closing the panel. The robot arms are mounted on at least one vertically oriented column adjacent a path of travel of the workpiece through a painting booth and the robot arms can be mounted on a common base.

An application system for coating components with a coating agent can include: (i) an application apparatus including a printing head which ejects the coating agent from a plurality of coating agent nozzles, wherein a nozzle valve which opens for a valve opening time when a coating agent droplet is to exit the respective nozzle is attached to each individual coating agent nozzle; (ii) a coating agent infeed line by way of which the coating agent nozzles of the printing head are collectively connected; (iii) a valve control for controlling the valve opening times and valve closing times of each individual valve; and (iv) a pump by means of which the coating agent to be applied is fed to the coating agent nozzles by way of the coating agent infeed line.

Disclosed herein is a cold spray system. The cold spray system comprises a nozzle unit comprising a coating nozzle member, configured to apply at least a portion of a metallic coating to a substrate. The cold spray system is configured to pre-heat the substrate before application of the at least a portion of the metallic coating to the substrate. Also disclosed herein is a method for applying a coating via a cold spray technique.

A holding mechanism holds a substrate horizontally. A rotation mechanism rotates the holding mechanism holding the substrate. A nozzle supplies a processing liquid to the substrate. A nozzle arm holds the nozzle. An arm actuation mechanism moves the nozzle arm between a processing position overlapping the substrate in plan view and a retracted position displaced from the substrate in plan view. A cup portion is disposed around the holding mechanism, and receives the processing liquid from the substrate. A cup actuation mechanism moves the cup portion up and down between an upper position and a lower position. A first container is fixed to the cup portion to be movable up and down integrally with the cup portion, and can accommodate the nozzle at the retracted position.

A pitch-yaw actuation system includes a pitch frame, a yaw frame, a pitch actuator, a yaw actuator, and a universal joint assembly. The pitch frame is pivotably coupled to a device frame via a pitch hinge. The yaw frame is pivotably coupled to the pitch frame via a yaw hinge. The pitch actuator pivots the pitch frame about a pitch axis. The yaw actuator pivots the yaw frame about a yaw axis oriented orthogonal to the pitch axis. The universal joint assembly couples the yaw actuator to the yaw frame, and includes a universal joint slidably coupled to a linear guide mechanism. The guide mechanism axis is oriented at an angle that allows the universal joint to move in a manner accommodating misalignment of the yaw actuator with the yaw frame during pivoting of at least one of the pitch frame and the yaw frame.
