FIG. 1 shows an embodiment of a crucible reuse processing apparatus according to the present invention.

As shown in the figure, the crucible reuse processing apparatus 1 generally includes a table 10, a handling device 20, a cutting device 30, a dust collecting device 70, and a coating device 50. It is configured. The drying room 6
0 is for drying the re-used crucible, and is basically the same as that used in the conventional method.

The carrier 6 carries a pallet 4 on which a plurality of, for example, 40, 8 × 5 crucibles 2 are placed, and includes a lifter 8. Accordingly, when the used crucible 2 which has been taken out of the internal melt for component inspection and the empty crucible 2 is arranged on the pallet 4, the cutting device 30 or the coating device 5
The lifter 8 can be lowered while moving to carry the pallet 4 to zero. Thereby, the work of arranging the crucibles 2 on the pallet 4 is simplified, or the stability during the movement can be increased. On the other hand, the pallet 4 is located at the position of the table 10 adjacent to the cutting device 30 and the coating device 50.
Is carried, the lifter 8 is raised and placed at a predetermined position on the adjacent table 10.

The planar arrangement of the handling device 20, the cutting device 30, and the coating device 50 has various variations. FIGS. 2A to 2C are schematic diagrams each showing a variation of the planar arrangement.

Since only one handling device 20 is required, there is an advantage that the equipment cost is reduced, and that extra work such as the movement of the pallet 4 by the carrier 6 can be reduced, thereby increasing the work efficiency.

In the planar arrangement shown in FIG.
A cutting device 30 and a coating device 50 are arranged side by side at right angles to each other, and a single handling device 20 supplies and collects the crucible 2 to both. As in the case of the planar arrangement of FIG.

Next, the handling device 20 will be described in detail with reference to FIG.

The handling device 20 includes a pair of rails 21 fixed to the bed 1 a of the crucible reuse processing device 1, and a total of four linear bearings 22 slidably mounted on the rails 21. A table 23 reciprocating in the direction of arrow X supported by a linear bearing 22, and a stand 24 erected on the table 23
And a horizontal frame 25 fixed to the upper end of the stand 24
A pair of shafts 26 reciprocating in the direction of arrow Y with respect to the horizontal frame 25, a head 27 fixed to the tip of the shaft 26, and a pair of shafts 28 reciprocating in the direction of arrow Z with respect to the head 27; , A hand 29 attached to the lower end of the shaft 28.

This handling device 20 basically has
Detailed description is omitted because it is well known in the art. In the case where a planar arrangement as shown in FIG.
For example, it is necessary to make the horizontal frame 25 rotatable about the vertical axis with respect to the stand 24.

Next, the cutting device 30 will be described in detail with reference to FIGS.

The cutting device 30 is generally composed of a body 30a
A first chuck 31 for detachably holding the crucible 2 substantially at the center of the body 30a, and a slide base 32 attached to the body 30a so as to be able to reciprocate up and down.
A rotating shaft 33 pivotally attached to the slide base 32 about a substantially vertical axis; a pair of chip supporting members 35 rotatably supported at the lower end of the rotating shaft 33; A plurality of cutting tips 36 fixed in position
It is composed of

In the preferred embodiment shown, the slide base 32 is driven up and down relative to the fuselage 30a by a lifting cylinder 32a fixed to the top of the fuselage 30a. Of course, other lifting mechanisms can be used. The rotation shaft 33 is driven at a predetermined rotation speed by a motor 34 via a V-belt, but another rotation drive mechanism can be used.

Further, in the illustrated preferred embodiment, a mounting hole 33e is formed at the lower end of the rotating shaft 33 so that the mounting shaft 33f having the horizontal arm 33a fixed to the mounting hole 33e does not relatively rotate. It is detachably attached. The attachment shaft 33f and the attachment hole 33e can be attached and detached with a single touch. When a crucible having a large diameter on the inner peripheral surface is cut, the attachment shaft 33

Note that a pair of chip support members 35 are rotatably supported at both ends of the horizontal arm 33a. As best shown in FIG. 7, the horizontal arm 33a is fixed to the lower end of the rotating shaft 33 by a bolt 33b. Horizontal arm 3
At both ends of 3a, a concave portion 33c penetrating in the vertical direction is formed, and an upper portion of the chip supporting member 35 is inserted into the concave portion 33c. The chip support member 35 is rotatably supported by a horizontal arm 33a by a substantially horizontal shaft member 33d.

The mounting shaft 33f further includes a support arm 33.
g is fixed substantially horizontally, and commercially available carbide tips 33h are attached near both ends thereof so as to slightly protrude downward, respectively. With this carbide tip 33h, the melt adhered to the upper end surface of the crucible 2 is scraped off.

When the rotating shaft 33 rotates in the direction of arrow R,
Due to the centrifugal force, the lower side of the chip support member 35 opens outward in the direction of the arrow S, and the cutting tip 36 fixed to the chip support member 35 moves along the inner peripheral surface of the crucible 2 held and fixed to the first chuck 31. It travels in the circumferential direction and scrapes off the adhered melt.

With such a structure, the pressing force of the cutting tip 36 against the inner peripheral surface of the crucible 2 can be easily adjusted by the number of rotations of the rotating shaft 33, and the crucibles 2 of different sizes can be cut by the same cutting device 30. Having. When the size of the crucible 2 is significantly different, it is preferable to replace the entire cutting tool as described above. In addition, even during cutting, there is room for the tip support member 35 to swing inward, so that it is possible to prevent an unreasonable cutting load from being applied to the crucible 2 and prevent the crucible 2 from being damaged.

Referring again to FIG. 7, three cutting tips 36 are screwed at predetermined positions on each tip support member 35.
As a result, the outer peripheral edge slightly protrudes from the chip supporting member 35 and is detachably fixed. In the preferred embodiment shown, the cutting tip 36 is disc-shaped and its outer peripheral surface is slightly inclined, as best shown in FIG. 8 (b). Cutting tip 36
Can be easily and inexpensively manufactured by, for example, powder metallurgy. Cutting tip 3 because of disk shape
When a part of 6 is worn down, the screw 36a can be loosened and slightly turned to change the portion that comes into contact with the inner peripheral surface of the crucible 2. Thus, the life of one cutting tip 36 is dramatically increased. In order to make the turning angle of the cutting tip 36 constant, irregularities can also be periodically formed on the surface where the cutting tip 36 and the chip supporting member 35 contact.

As best shown in FIG. 8 (a), the uppermost, middle and lowermost cutting tips 36 are each a relatively upper portion L of the inner peripheral surface of the crucible 2.
