A coating device for applying a coating agent to the surface of a workpiece. The coating device includes a frame having a workpiece receptacle, a coating agent source, a compressed air source, and a rotary unit which is rotatable in relation to the frame. The rotary unit has a pump and a plurality of spray units, the pump on the suction side being connected to the coating agent source by a fluid-conducting rotary joint connection, and on the pressure side being connected to the spray units. The rotary unit has a pneumatic valve device, and the spray units have in each case one compressed air controlled valve for controlling the delivery of coating agent. The valve on the inlet side is connected to the compressed air source by a fluid-conducting rotary feedthrough and on the exhaust air side is connected to the compressed air controlled valves of the spray units.

A machine tool chip removal device including a coupling interface to couple with a rotatable spindle of a machine tool to facilitate rotation of the machine tool chip removal device about an axis at a rotational speed. The chip removal device can also include a main fluid channel with an opening to receive pressurized fluid from the machine tool. The chip removal device can further include a first fluid delivery channel and a second fluid delivery channel to direct fluid in different directions. Each fluid delivery channel can be in fluid communication with the main fluid channel. In addition, the chip removal device can include one or more valves associated with the first and second fluid delivery channels to selectively allow fluid passage from the main fluid channel to the fluid delivery channels. The one or more valves can be actuated by varying fluid pressure and/or rotational speed.

The disclosure concerns a spray bottle assembly for use with an atomized-spray dispensing device. The spray bottle assembly generally includes a bottle containing an amount of cosmetic composition, a release mechanism having a port associated therewith, an insert with an insert lumen configured to engage the port for communicating the cosmetic composition therethrough, a nozzle for configuring a stream of the cosmetic composition expelled from the spray bottle assembly, a mixing chamber for mixing compressed air with the stream of the cosmetic composition, and a spray aperture for communicating atomized spray. The spray bottle assembly is designed for use with equipment having corresponding release elements for engaging the insert and release mechanism of the bottle.

An unmanned aerial vehicle (UAV) includes a sprayer configured to generate a pressurized fluid flow and a nozzle configured to receive the pressurized fluid from the sprayer and to generate a spray fan to apply the fluid to a surface. The UAV includes sensors and a control unit to control both flight of the UAV and spraying by the sprayer. The fluid can be stored onboard the UAV in a reservoir or can be remotely stored and pumped to the UAV. The UAV control unit can be preloaded with a spray plan and a flight plan, or the UAV can be controlled by a user.

The present invention generally relates to methods of printing articles using three-dimensional printing and other printing techniques, and to articles formed from such techniques, including the printing of articles of footwear containing particles. Certain embodiments are generally directed to composites comprising particles (e.g., reinforcing particles), for example, rubber particles. The particles may be used, for example, to increase slip or abrasion resistance. The composites may also contain polyurethanes or other compounds, e.g., to facilitate fabrication, e.g., using three-dimensional printing and other printing techniques. Other embodiments are directed to methods of making or using such articles. For example, in some embodiments, a composite may be prepared by mixing particles (e.g., reinforcing particles) with at least a first fluid and a second fluid within a nozzle, such as a microfluidic printing nozzle, which may be used to direct the resulting product onto a substrate.

An automated painting system that includes a robotic arm and a painting end effector coupled at a distal end of the robotic arm, with the painting end effector configured to apply paint to a target surface. The painting system can also include a computing device executing a computational planner that: generates instructions for driving the painting end effector and robotic arm to perform at least one painting task that includes applying paint, via the painting the end effector, to a plurality of drywall pieces, the generating based at least in part on obtained target surface data; and drives the end effector and robotic arm to perform the at least one painting task.

Apparatus (1) for applying paint comprises a device (40) for applying paint that comprises a plurality of spray guns (26) that is movable along a closed path having two parallel sides connected by two circular arcs, a rotating joint (43) for supplying paint provided with a distributor and comprising a plurality of tube-support chains (44), each tube support chain (44) connecting the distributor of the one rotating joint (43) for dispensing the painting product to a respective gun of said spray guns (26), in which each tube support chain (44) has an inverted U-shape provided with two ends, of which—the first end is connected to a first rotating support (61), which is connected to the rotating joint (43) and follows a circular trajectory, while—the second end is connected to a second rotating support (62), which is connected to a support arm (41) of a respective gun (26) and follows in use the trajectory defined by said closed path.

The disclosure concerns a coating device and a corresponding coating process for coating components, in particular motor vehicle body components, with a coating agent (e.g. paint), with a coating robot with a first printhead which is mounted on the coating robot. The disclosure provides that the first printhead is exchangeably mounted on the coating robot and can be exchanged for a second printhead during a color change. Another variant of the disclosure, on the other hand, provides for a second printhead to be mounted on the coating robot in addition to the first printhead, the two printheads each applying a specific coating agent in order to enable a color change without changing the printhead.

An ink-jet coater and a coating method for improving smoothness of a mixed part where the coating position in the previous scan overlaps the coating position in the next scan includes a robot arm configured to move a nozzle head unit by driving arms via an arm driving mechanism and a coating control unit configured to control driving of the nozzle driving mechanism and driving of the arm driving mechanism to execute coating on the coating object. The coating control unit performs coating by forming, in segmented coating surfaces formed by each scanning of the nozzle head unit, a normal coating region coated with a target coating film thickness and an overlapping coating region coated with a spray amount of the paint less than the normal coating region.
