When one of the ladles 30 is supported by the ladle transfer body 204 to perform the pouring operation, the other is used. The ladle 30 is heated (preheated). If the temperature of the ladle 30 is low, the temperature of the hot water drops rapidly when receiving the hot water from the melting furnace.

On the base 231, there is a ladle support 232,
A moving mechanism 234 for a furnace body 233 that opens and closes an open upper portion of the ladle 30 held on the ladle receiving table 232 is provided. The ladle support 232 has a pair of left and right holding plates 235, and at the upper end of the holding plate 235,

One shaft 242 of the pair of left and right parallel arms 240 is connected by a drive shaft 243, and the drive shaft 243 is driven by a cylinder device 244 and its drive arm 245. By this parallel movement mechanism, the furnace body 233 is completely retracted from the position where the upper surface opening portion of the ladle 30 on the ladle receiving stand 232 is closed and from the ladle receiving stand 232 while maintaining the substantially horizontal state. Move between positions.

The pouring stage 200 is further provided with two melting furnaces 250 having the same structure, which are located on opposite sides of the mold set line 21 (FIGS. 1 and 14). This melting furnace 250 melts the cast metal charged into the furnace 251 by, for example, high-frequency heating, and has a spout 25 at its tip.
2 The furnace 251 can be tilted to a pouring position in which the spout 252 is directed downward by a tilting mechanism (not shown). As such a tilting mechanism, various mechanisms such as manual, hydraulic, and electric are known. The ladle 30 held by the ladle transfer body 204 is connected to the X-direction rail 202 and the X-direction traveling body 20.
The three-axis and Z-axis actuators 205 can move the X-, Y-, and Z-axis driving mechanisms to a position for receiving hot water from the spout 252 of the furnace 251.

The flow of the pouring operation in the pouring stage 200 having the above configuration will be described below. Cast metal is put into at least one of the two melting furnaces 250 and melted at a predetermined temperature. On the other hand, two ladle heating devices 230
Each of the ladle 30 is held on a ladle receiving stand 232 of the
And ignite the gas burner 238 to heat the ladle 30. When the ladle 30 is sufficiently heated, the furnace body moving mechanism 234
The furnace body 233 is moved to the retreat position by the (parallel movement mechanism). At the same time, the ladle transfer body 2 is driven by the servomotor 213.
04, the crank arm 209 (tilt pin 211) is held at the non-tilt position, the ladle lid 206 is held at the open position by the open / close cylinder device 223, and the three-axis drive mechanism
The ladle transfer body 204 is moved to the vicinity of the ladle 30 being heated. Immediately after the furnace body 233 is retracted from the ladle 30, the tilting pin 211 and the hook 217 are positioned and raised below the tilting force projection 34 and the small diameter portion 36b of the tilting center boss 36, respectively. Thus, the reception of the ladle 30 from the ladle heating device 230 to the ladle transfer body 204 is completed.

Next, the ladle transfer body 204 having received the heated ladle 30 is moved near the melting furnace 250, and the furnace 251 is tilted in the state shown in FIG.
The hot water from 52 is received in the ladle 30. Upon receiving the hot water, the opening / closing cylinder device 223 closes the ladle lid 206 to prevent the temperature of the hot water from dropping, and moves the ladle transfer body 204 onto the mold W on the hearth pallet 10 stopped on the casting line 25. And the ladle 30 is set at an appropriate height position.
A sensor may be used for setting the plane position and the height position of the ladle 30. Of course, the mold W (hearth pallet 10)
Before being sent to the pouring stage 200 by the casting line 25, the preheating stage 100 is sufficiently heated by the heating means (the combustion unit 104, the gas burner 105, and the exhaust pipe 106) of the heating casing 101.

Next, when the servomotor 213 is driven to raise the crank arm 209 (tilt pin 211), the ladle 30 is tilted about the tilt center boss 36 and held by the ladle 30. Hot water is poured from the spout 33 into the mold W. When the predetermined amount has been poured, the servomotor 213 is rotated reversely, and the ladle 30 is returned to the non-tilt position again. Hereinafter, pouring is similarly performed for all the molds W.

The tilting operation of the ladle 30 (at the time of pouring)
It is desirable that the tilting speed at the time of returning (stopping the injection) be slower in going and faster in returning. Slowing the water can prevent the hot water from spilling, and returning early can improve the drainage of the spout 33, thereby similarly preventing the hot water from spilling. By detecting the rotation direction of the servomotor 213 and performing microcomputer processing, such control can be freely performed.

In parallel with the above pouring operation, one of the two ladle heating devices 230 closes the upper opening of the ladle 30 held on the ladle receiving stand 232 with the furnace body 233, and the gas burner 238. Ignite and heat. In addition, hot water is made in one of the two melting furnaces 250. When the hot water in the ladle 30 held by the ladle transfer body 204 becomes empty, the ladle 30
Is transferred to an empty ladle receiving table 232 of the two ladle heating devices 230 to receive the heated ladle 30. When the ladle 3 held by the ladle transfer body 204 is transferred to the ladle receiving table 232, the small diameter portions 35 a and 36 a of the holding bosses 35 and 36 are held by the holding plate After being placed in the grooves 236 and 237, the tilting pin 211 and the hook 217 (the ladle transfer body 204) are lowered.

The movement of the ladle transfer body 204 in the three axial directions and the driving of the servo motor 213 constituting the ladle tilting device are performed while the operator visually observes the positions of the ladle 30 and the mold W.
However, by detecting the position of the ladle 30 and the position of the mold W with a sensor, a part or all of this operation can be released from the sense of the operator.

The casting mold W after the pouring operation in the pouring stage 200 is sent to the next decarburization prevention stage 300 by the hearth pallet 10 and subjected to decarburization prevention processing. The next mold W is set on the empty hearth pallet 10 in the mold setting line 21 and sent to the preheating stage 100, the pouring stage 200, and the decarburization prevention stage 300 via the standby line 22. Hereinafter, by repeating the above operation, the pouring operation for the mold W can be performed extremely efficiently.
