A pouring device 9 is mounted on the first traversing cart 7, and a working device 10 such as a brushing device or a coating agent spraying device is mounted on the second traversing cart 8.

A moving device 11 for these traversing carts 7 and 8 is disposed on one side of the standby guide rail 5, and is arranged between the moving device 11 and the first traversing cart 7 and between the first traversing cart 7 and the second traversing cart. 8
A connecting device 12 is interposed between the two, which connects each other in the transverse direction and allows relative movement in the front and back direction.

This coupling device 12 is composed of, for example, a T-shaped member 13 and a pair of L-shaped members 14a and 14b that engage with both ends of the flange.

As shown in FIGS. 3 and 4, the moving device 11 includes a moving body 16 that is movable on a guide rail 15 disposed parallel to one standby guide rail 5, and a moving body 16. 16
and a fixed frame 17 near the end of the guide rail 15 on the side opposite to the longitudinal movable trolley 3 side.
8, and a cylinder device 19 that deforms the link mechanism 18 and drives the movable body 16 to move.

Each stop position of the first traversing truck 7 and the second traversing truck 8,
That is, one pair each located at the center of the longitudinal movable bogie 3, at the center of the first transverse bogie 7 stop position on one standby guide rail 5 side, and at the center of the second transverse bogie 8 stop position on the other standby guide rail 6 side. A truck positioning device 20 is provided.

As shown in FIG. 5, this cart positioning device 20 includes a rotatable engaging body 21 having a tapered engaging surface 21a at its tip, a support bracket 22 for the engaging body 21, and a cylinder for rotationally driving the engaging body 21. Attachment. A block 24 having a recess (not shown) into which the tapered engagement surface 21a of the engagement body 21 fits is provided on the side of the transverse carriages 7 and 8.

Thus, when moved by the moving device 11 via the coupling device 12, there is a gap between the members of the coupling device 12, so each of the transverse carts 7, 8 is not in an accurate position, and the members are not engaged with each other. However, by engaging the engaging body 21 of this cart positioning device 20 with the block 24 of the traversing carts 7, 8, each of the traversing carts 7, 8 is slightly moved, and the position between the members of the coupling device 12 as shown in FIG. An appropriate gap is formed to allow smooth back and forth movement of the transverse carriage 7 or 8 on the longitudinally movable carriage 3, and accurate positioning and fixation of each transverse carriage 7 or 8 is achieved.

The pouring device 9 is installed on a lifting platform 25 that is installed on the first traversing cart 7 so as to be able to move up and down via X-shaped link mechanisms 26a and 26b.

27 is a pouring trough extending in a cantilevered manner from the end of the lifting platform 25 on the rotary mold 1 side, and a trough support bracket 28
The base end of the pouring trough is connected to a chute 29 which is also supported by the lifting platform 25.

30 is a pouring ladle. It is tiltably supported by a bracket 31 erected from the lifting table 25, and is tilted by a drive device 32 to pour molten metal onto a chute 29, and these pouring ladle 30, chute 29 and the pouring trough 27 constitute a pouring device 9.

Next, to explain the operation, the rotary mold 1 is driven to rotate, and with the second transverse carriage 8 placed on the longitudinally movable carriage 3, the longitudinally movable carriage 3 is moved toward the rotary die 1, and as appropriate. After the inner surface of the rotary mold 1 is subjected to treatments such as brushing using the working device 10, it is coated with a mold coating agent.

When coating is completed, the back-and-forth moving carriage 3 returns to the standby position, the moving device 11 is activated, and the moving body 16 moves back and forth to the back-and-forth moving carriage 3.
moving toward the side, and the first traversing trolley T moves along with it.
The second traversing truck 8 is pressed and moved to the left in FIG. 4 Transfer to the top.

Thereafter, when the carriage positioning device 20 operates and the transverse carriages 7 and 8 are fixed at predetermined positions without interfering with each other as shown in FIG. 3, the longitudinally movable carriage 3 immediately moves forward.

While the back-and-forth movable cart 3 moves backward again from the forward limit position, the pouring ladle 30 is gradually tilted by the driving device 32, and the molten metal flows through the chute 29 and the pouring trough 27 and is deposited on the inner surface of the rotary mold 1. It is poured into the target.

When the tip of the pouring trough 27 reaches the end of the rotary mold 1, pouring is completed, and the pouring ladle 30 is quickly returned to its original horizontal position.
The back-and-forth movable truck 3 returns to the standby position.

Next, the moving device 11 operates and the moving body 16 moves to the fixed frame 17.
Along with this, the first traversing truck 7 and the second traversing truck 8 are pulled to the right in FIG. , the first traversing cart 7 is transferred onto one of the standby guide rails 5, and fixed at a predetermined position by the cart positioning device 20.

On the other hand, once the molten metal has solidified in the rotary mold 1 and a cast tube has been cast, the rotary mold 1 is stopped, the cast tube is pulled out, and the same operations as described above are repeated.

Note that while the first traversing cart 7 is on standby, molten metal is supplied into the pouring ladle 30, and at this time it is measured by a measuring device (not shown) provided on the lifting platform.

Further, the height of the pouring trough 27 during pouring into the rotary mold 1 is adjusted by raising and lowering the lifting table 25 using the link mechanisms 26a and 26b.

As is clear from the above description, the centrifugal casting apparatus of the present invention includes a back-and-forth movable carriage and a pair of transverse carriages that move in a waiting position relative to the carriage, and various working devices are mounted on each transversal carriage. Therefore, the configuration of each truck is simple, and only one drive device for the longitudinally moving truck that requires control is required, resulting in low cost, and the operation time is shortened, resulting in improved productivity.
