The agitation means 94 is rotated counterclockwise in FIG. 2 via the agitation means 94, and the powder in the accommodation space P is thus agitated at this time as well.

When moved in this manner, the upper shutter member 24 opens the upper opening of each measuring chamber 44, and the lower shutter member 50 covers the lower opening of each measuring chamber 44, and the powder stored in the accommodation space P is It is made to flow into each measuring chamber 44 from the upper opening.

The above-mentioned action is continuously repeated by the expansion and contraction of the fluid pressure cylinder mechanism 62, and the powder in the accommodation space P is continuously discharged.

Adjustment of the powder supply amount discharged from the metering chamber 44 is achieved by rotating the adjustment rod 34 or 40. To explain further, when an operating handle (not shown) is attached to the other end of the adjustment rod 34 and rotated in a predetermined direction, the fill adjustment rod 24 moves into the mounting notch 30 of the movable member 26 and With the measuring notch 22Ka of the stationary member 12,
It is moved in a direction approaching (or away from) the stationary member 12, and the total volume of one chamber 44 is decreased (or increased). Therefore, when such an operation is performed, each measuring chamber 44
The volume of each is adjusted individually. On the other hand, when an operating handle (not shown) is attached to the other end of the adjustment rod 35 and rotated in a predetermined direction, the movable member 26 to which the metering adjustment member 24 is attached approaches the stationary member 12 ( The volume of each measuring chamber 44 is simultaneously decreased (
or increase). Therefore, when the above-described operation is performed, the volumes of all measuring chambers 44 are adjusted at once.

As shown in FIG. 3, the position adjustment table 230 has a disc shape, and its periphery is rounded. ,□Good□,. 8 □ 232 (provided corresponding to the measuring notches 218 formed in the rotary table 208, and eight in the specific example) are formed. Cam groove 232
Each of the position adjustment daples 2300 is formed to be inclined at a predetermined angle with respect to the radial direction, that is, the sliding direction of the metering adjustment member 222 disposed in the metering notch 218 of the rotary table 208, as will be understood from the following description. Each of the driven rollers 226 attached to the metering adjustment member 222 is
are received within each cam groove 232. As described above, in this specific example, each of the one chamber 234 for measuring the powder is located on the inner surface of the side wall 204, on both sides of the measuring notch 218 formed in the rotary table 208, and in the measuring notch 21.
It is defined by the hanging portion 222b of the metering adjustment member 222 disposed at 8. Then, the metering notch 21 is moved in the direction of moving the metering adjustment member 222 closer to or away from the inner surface of the side wall 204.

Open the bottom of the tip and insert it. The other end of this passage 252 is connected to a compressed air supply source (not shown) via a tubular chain (not shown).

Next, the effects of the second specific example will be explained.

As the rotary table 2080 rotates in the direction indicated by the arrow 214 by the action of a drive source (not shown),
First, between both powder discharge parts 244, there is a total of one chamber 234.
Although the lower opening of the housing is closed by the bottom wall 206, the upper opening thereof is open, so that the powder in the storage space P flows into the measuring chamber 234. Next, the powder discharge section 24
4, the upper opening of the metering chamber 234 on the introduction side is closed by the upper wall 246a of the discharge housing 246, and a predetermined amount of powder to be supplied is metered by the metering chamber 234. Thereafter, when positioned over the discharge opening 248 of the bottom wall 206, the upper opening of the metering chamber 234
46a, but since its lower opening is open, the powder in the metering chamber 234 is discharged through the lower opening, the discharge opening 248, and the discharge pipe 250. When discharging the powder, compressed air from a compressed air source (not shown) is supplied through the air supply passage 252 to the metering chamber 234 located above the discharge opening 248, and the action of this compressed air causes the metering chamber 44 to The powder inside is reliably discharged and transported. In this specific example, as can be easily understood from FIG. The powder in the space P is stirred as required.

The above-mentioned passing action is continuously performed by rotating the rotary table 208 in the direction shown by the arrow 214, and the powder in the storage space P is measured in the measuring chamber 234 and continuously discharged.

Adjustment of the powder supply amount discharged from the measuring chamber 234 is performed at position 114 with respect to the rotary table 208! i table 230
This is achieved by relatively moving (9).

To explain further, when the mounting portion 228 is rotated in a predetermined direction, the position adjustment table 230 becomes rotatable relative to the rotary table 208.

In this state, for example, the position adjustment table 230t-jIa is rotated by a predetermined angle clockwise relative to the rotary table 208 (as understood from FIG. 4, this operation involves gripping the cover member 242 and adjusting the position (This can be accomplished by rotating the adjustment table 230 in a predetermined direction), and as shown in FIG. 232, and the metering adjustment member 222 is positioned from a first position shown in broken lines in FIG. 5 to a second position shown in two-dot chain lines in FIG. 5 along metering notch 218. It will be done. Thus, the volume of each metering chamber 234 is simultaneously increased.

On the other hand, for example, when the position adjustment table 230 is rotated counterclockwise in FIG. 3 relative to the rotary table 208, the volumes of the measuring chambers 234 are simultaneously reduced, as is easily understood. Since the above is the general rule,
In this specific example, the volumes of all measuring chambers 44 are adjusted to the required volume at once.

Although a specific example of the powder supply device configured according to the present invention has been described above, the present invention is not limited to such an integral part of the tool 27, and various modifications and changes can be made without departing from the scope of the present invention. is possible.

For example, in the specific example, the measurement space is formed by a notch, but if desired, a through hole may be formed instead, and the measurement space may be formed by this through hole. .
