に自動配湯されるようにしている。<Prior art> Conventionally, in an aluminum die casting factory shown in FIG. 3 as an example of a foundry, aluminum alloy ingots, which are casting materials, are melted and stored in a melting furnace 20, while running on rails 3 installed on the ceiling. The molten aluminum alloy is pumped up from the pumping port 21 of the melting furnace 20 by a vertically moving ladle 2 (see Fig. 1) provided on the carrier 1, and transported to the holding furnace 4 provided in each die-casting machine 22 as necessary. An automatic hot water distribution system has been adopted. When the factory is in operation, aluminum alloy ingots are fed into the melting furnace 20 as needed, and the molten metal level in the melting furnace is maintained at a normal level considerably higher than the upper end of the ladle lowered to the bottom of the furnace. , when the hot water level in each holding furnace 4 falls below a predetermined high level, the hot water level sensor detects this and the hot water distribution control device 23
Based on this signal, the hot water distribution control device 23 calls the carrier 1 and automatically distributes hot water to the holding furnace.

うにしたものである。 However, if molten metal is left in the furnace on weekends when the factory is closed and the melting furnace 20 is stopped, the molten metal will solidify and it will be difficult and uneconomical to melt it when restarting operations. It is necessary to discharge all the molten metal, including the remaining molten metal below the upper end of the ladle that cannot be pumped up by the ladle, out of the furnace, and distribute the discharged molten metal to each holding furnace 4. for example,
In the case of a melting furnace with an aluminum melting capacity of 750Kg/hour,
While the amount of molten metal that can be pumped below the normal use level is 0.7 tons, the amount of remaining molten metal that cannot be pumped reaches approximately 1 ton. Therefore, the inventors recently
We have proposed a hot water distribution system that can safely and efficiently distribute this large amount of remaining hot metal to the holding furnace 4 by effectively utilizing the carrier 1 (Utility Application No. 61-135902).
issue). This dispensing device has a ladle 24 whose upper end is located near the melting furnace 20 and below the bottom of the melting furnace, and which has a cross section smaller than that of the melting furnace and can accommodate the ladle 2. The ladle is raised to the lowering limit of the ladle by means of a lifting platform.

Since the hot water level in each holding furnace 4 is maintained at a high level by the hot water level sensor as described above, a new problem has arisen. That is, since each holding furnace 4 is maintained in a state close to full, there is almost no margin in its molten metal storage capacity, and the only option is to reduce the amount of molten metal due to the consumption of molten metal in each die-casting machine 22. The drawback was that it took too long to process the hot water, and the remaining hot water could not be disposed of in a short period of time.
そこで、本考案の目的は、各保持炉の湯面を残

The purpose is to provide equipment.

The hot water distribution control device of the present invention automatically controls the hot water distribution operation based on the output of the hot water level detection means that detects the hot water level of each holding furnace. A hot water level detecting means for detecting the hot water level is provided, and a selection switch is provided for selecting and outputting either a high hot water level signal or a low hot water level signal output from the hot water level detecting means. shall be.

間の間に分配されてしまう。<Operation> Prior to processing the remaining metal in the melting furnace, the operator switches the selection switch of the metal distribution control device to the low level side. Then, the low molten metal level detection means of each holding furnace is sent to the molten metal distribution control device via the selection switch only after the molten metal in the holding furnace is consumed by a die-casting machine etc. and the molten metal level falls below a predetermined low level. The hot water distribution control device outputs a low hot water level signal,
Based on this signal, a carrier is used to supply the molten metal from the melting furnace to the holding furnace. As a result, the hot water level in each holding furnace is maintained at the predetermined low level. Next, when processing the remaining melt in the melting furnace, the operator switches the selection switch to the high melt level side. Then, the high melt level detection means of each holding furnace will input a signal to the hot water distribution control device via this selection switch, and the hot water distribution control device will detect when the hot water level in the holding furnace has reached a predetermined high level. The carrier continues to supply the remaining molten metal of the melting furnace to the holding furnace until the high molten metal level detection means outputs a high molten metal level signal. In this way, the remaining melt in the melting furnace is
The molten metal is distributed within a short period of time to each holding furnace that has sufficient capacity to accommodate the molten metal.
