An electrostatic coating method in which a plurality of coating materials is respectively retained in a plurality of coating-material containers in a coating material cartridge, and the coating materials are changed by a valve at the time of sending of each of the coating materials, in an electrostatic coating device, each of the coating materials is sent from the coating material cartridge to a coating machine via a common path according to the change, and multilayer coating is performed by the electrostatic coating device.

Electrostatic coating device and electrostatic coating method

An electrostatic coating device and an electrostatic coating method each achieve a reduction in working hours and efficient coating at the time when layers are coated with colors. The electrostatic coating device includes a coating material cartridge that includes coating-material containers, a valve that makes a change of colors of coating materials, a common path through which coating materials are able to pass according to the change, and a cleaning circuit that cleans up the common path. The coating material cartridge is configured to be removable from a coating machine. The coating material cartridge may include individual paths respectively connected to the coating-material containers and each of which one of the coating materials passes through, and valves each connected to the common path and respectively connected to the individual paths. Each of the valves may open and close a conduit line between the common path and a corresponding coating-material container.

A multi-joint finger unit () has first and second joint sections () constructed by using bevel gears. In each joint section (), the section where a driving bevel gear () and a driven bevel gear () mesh with each other and also a bearing section of a joint shaft () are assembled in a tubular housing () whose forward end is closed. Rear end openings (A,) of the tubular housings () are closed by a tubular housing () at a finger root and a tubular housing () at a finger body section. The section where the gears of the joint sections () mesh and the bearing section are substantially sealed, so that a foreign matter is prevented from entering from the outside to these sections and lubricant does not leaks from these sections. The multi-joint finger unit is suitable for use in place where thick powder dust is present and in a clean room.

Finger unit for robot hand and method of assembling the same

A sealed worm gear type finger joint unit for a robot hand has a circular opening in a gear box case of the unit, and the opening is closed by a rubber bush. When the rubber bush is removed, a shaft end face of a worm shaft section is exposed from the circular opening, and this makes a tool engagement section formed on the shaft end face is accessible from the outside. A tool for turning the worm shaft section is fitted in the tool engagement section, and the worm shaft section can be easily turned by the tool. Turning the worm shaft section turns a worm, turning a worm wheel meshing with the worm, and this turns the joint shaft. As a result, a swing arm connected to shaft end sections of the joint shaft can be moved to a predetermined position. In the finger joint unit, the joint shaft can be easily manually turned.
