Abstract
A powder supply apparatus includes a measuring shaft having a recess to be filled with powder, and a powder filling mechanism for filling the recess of the measuring shaft with the powder. The powder supply apparatus includes a rotary cylinder for sliding the measuring shaft along an axis of the measuring shaft, and a distal-end cover plate of a cylinder where the powder in the recess is leveled off by a slide of the measuring shaft. The rotary cylinder directs the recess downward by rotating the measuring shaft about the axis of the measuring shaft and supplies the leveled powder in the recess downward from the recess to a lifting plate at a predetermined position by dropping the powder.
Claims8
A powder supply apparatus comprising:
- a measuring shaft having a recess to be filled with powder;
- a powder filling mechanism for filling the recess of the measuring shaft with the powder;
- a slide mechanism for sliding the measuring shaft along an axis of the measuring shaft;
- a leveling member for leveling off the powder in the recess by a slide of the measuring shaft;
- and
- an axial rotation mechanism that directs the recess downward by rotating the measuring shaft about the axis of the measuring shaft and supplies the leveled powder in the recess downward from the recess by dropping the powder,
- wherein the powder filling mechanism includes:
- a cylinder in which at least the recess of the measuring shaft is allowed to be placed and the powder is disposed;
- and
- a cylinder rotation mechanism that rotates the cylinder so as to agitate the powder in the cylinder and fill the recess with the powder.
A powder supply apparatus comprising:
- a measuring shaft having a recess to be filled with powder;
- a powder filling mechanism for filling the recess of the measuring shaft with the powder;
- a slide mechanism for sliding the measuring shaft along an axis of the measuring shaft;
- a leveling member for leveling off the powder in the recess by a slide of the measuring shaft;
- and
- an axial rotation mechanism that directs the recess downward by rotating the measuring shaft about the axis of the measuring shaft and supplies the leveled powder in the recess downward from the recess by dropping the powder,
- further comprising a detector for detecting a filling state of the powder in the recess after the powder is leveled off by the leveling member;
- and
- a control mechanism that causes the slide mechanism to slide the measuring shaft to a position for filling the recess with the powder and causes the powder filling mechanism to fill the recess with the powder if the detector detects an insufficient filling state of the powder.
