"Function" Examples of the fluid to be ejected from the ejection head include air, light oil, etc.In the case of air, debris such as chips adhering to a predetermined surface of the target object is blown away and cleaned.On the other hand, light oil In this case, lubrication, cooling, etc. are performed at the same time.

When a fluid such as air or light oil is injected from an injection port of a rotating body, the rotating body automatically rotates relative to the injection head due to the reaction force. The direction of the ejection port is also set so that the fluid collides with a predetermined surface of the object, so that the fluid ejected from the ejection head can evenly clean the predetermined surface of the object.

[Example] Next, a rotary air blower and a rotary fluid injection device of the present invention will be described in detail with reference to the drawings.

In FIG. 1, movable arm 14 corresponds to movable arm 4 in FIG. 6. A pair of workpiece gripping means 15 and 16 having the same structure are attached to the tip of the movable arm 14, and are used for loading and unloading, respectively. A pair of workpiece gripping means 1
5.16 is capable of half a rotation about the central axis 17 of the movable arm 14 as a fulcrum.

The workpiece gripping means 15 has a chuck part 15a for gripping the workpiece B to be processed and a main body part 5b for driving the chuck part 15a.

As shown in the drawing, the rotary air blowing device of the present invention schematically includes an injection head 21, a rotating body 22 rotatably attached to the injection head 21, and
It consists of a bearing 23 mounted between an injection head 21 and a rotating body 22.

The injection head 21 has an air passage n 21 a,
It is connected to an air supply source (not shown) via a pipe 20.

In the illustrated preferred embodiment, this pipe 20
is fixed to the movable arm 14 by a mounting bracket 24.

The rotating body 22 has a base 22a rotatably attached to the injection rod 21, and a pair of legs 22b extending radially from the base 22a. An air passage FM 22 c fluidly connected to the air passage 21 a of the injection head 21 is formed inside the base 22 a and the pair of legs 22 b.

Each leg 22b is provided with injection ports 22d arranged in a row along its longitudinal direction.

The injection ports 22d are inclined at the same angle in the rotation direction with respect to a plane including the rotation center of the rotating body 22.

The V-angle of the injection port 22d is in the range of about 3 to 85 degrees. In the preferred embodiment shown, the injection port 22d
The inclination angle is approximately 25 degrees.

The number and direction of the injection ports 22d may be any number or direction as long as the rotating body 22 automatically rotates due to the reaction force of the air injected from the rotating body 22 and the air collides with a predetermined surface of the object i. Any angle is fine.

Each leg portion 22b is also provided with a line of brushes 22e parallel to the injection port 22d. The brush 22e is for sweeping away dust such as large chips adhering to the unprocessed workpiece B, and small dust is blown away and cleaned with air from the jet nozzle 22d.

Although not shown, it is preferable to install a cover around the rotary air blower to prevent blown dust from scattering.Furthermore, if the dust is actively sucked out by a suction device, the working environment can be purified. can be achieved.

Although the present invention has been described above with respect to a rotary air blower, a liquid such as light oil can also be used instead of air.

[Effects of the Invention] As explained above, the rotary air blowing device of the present invention! is a rotating body having radial legs rotatably attached to the jetting head, the legs being formed in a line along the longitudinal direction fluidly connected to the air passage of the jetting head. It has a nozzle, and the nozzle is inclined at the same angle in the direction of rotation with respect to the plane that includes the center of rotation of the rotating body, so the jet head can be automatically rotated by injecting air. As a result, it is possible to blow off and clean debris such as chips that have adhered to a predetermined surface of the object.

By adopting such a configuration, the mechanism for gripping the object can be made simple, and it also has the secondary effect of facilitating rotation control of the manipulator and the like.
