Furthermore, when producing a mold, information specific to the casting product to be cast by the mold can be input into the control computer.

(Function) Since the casting line control device configured as described above is configured as described above, the unique information of the cast product to be cast by the mold corresponding to the mold is input to the control computer. However, in the casting line, when the mold reaches a required work step, specific information about the cast product to be manufactured by this mold can be obtained from the control computer.

Note that it is suitable that the information specific to the casting product is input into the control computer when the casting mold is manufactured.

〔Example〕

Hereinafter, the present invention will be explained in detail based on FIG.

In the figure, T is a mold transport line, including an upper mold transport line, a lower mold transport line 2, a series of trolley lines 3, -
It is composed of a secondary cooling line 4, a secondary cooling line 5, and a cooled product conveyance line 6.

Addresses 1 to 322 are determined on this mold conveyance line T, and the molds are shifted over these addresses.

Next, the mold conveyance line T will be explained in detail.

11 is an upper mold making machine, and 21 is a lower mold making machine, which manufactures an upper mold 111 or a lower mold 211 that functions as a mold. At the stage of molding the upper mold 111 and the lower mold 211, information on the mold ("information on the cast product to be cast by the mold", the same shall apply hereinafter) corresponding to the mold, for example,
The amount of poured metal, the amount of poured metal, the amount of additives, the necessity of annealing time, the ratio of the poured amount to mold sand, etc. are sequentially recorded in the control computer C. Therefore, if the information on the mold (upper mold and lower mold) currently being manufactured is known, the control computer C can know the growth information of the mold M at any other address on the mold transport line T. The upper mold 111 manufactured by the upper mold molding machine 11 is transferred to the upper mold conveying line 1, and the lower mold 211 manufactured by the lower mold molding machine 21 is transferred to the lower mold conveying line 2 by the weight of the bogie line 3. It is transported to position 31. Note that a roller conveyor is suitable for both the upper die conveying line 1 and the lower die conveying line 2.

Next, the bogie line 3 is made up of bogies connected at regular intervals. The upper mold 111 and the lower mold 211 are placed on a truck as a mold M while aligning the frames at a position 31 where a weight is placed. The mold M moves in the direction of the arrow as the cart moves, and reaches the pouring position 32. At this time, since information on the mold M shifted to the pouring position 32 can be known by the control computer C, the amount of poured metal, the amount of poured metal, and the presence or absence of additives are automatically determined according to the information of the mold M. Hot water is poured. Note that the pouring time is newly input into the computer as information about the mold M. After pouring, the mold M shifts in the direction of the arrow along the trolley line 3 while cooling naturally, and when it reaches position 33, the mold M The frame 7 is removed and the mold M is pushed out into the primary cooling line 4 (consisting of a roller conveyor). Then, the empty frame 7 is transported by a conveyor 71 as appropriate in the direction of the molding machine 11.21. Further, the empty cart is shifted via the cart line 3 toward the position 31 where the weight is placed.

The mold M that has entered the primary cooling line 4 reaches a branch point 41 at the end of the line 4 while shifting the secondary cooling line 4 . At this time, since information on the mold M shifted to the branch point 41 can be known by the control computer C, the mold M is automatically moved to either the cooled product conveyance line 6 or the secondary cooling line 5 according to the information. Line 6°5 will be selected. That is, the mold M
Items that have "need for time to use annealing" as information are pushed out to the secondary cooling line 5, and items that do not have such information are pushed out to the cooled product conveyance line 6. Note that when the mold M is extruded into the secondary cooling line 5, a cooled mold M is extruded from the secondary cooling line 5 to the primary cooling line 4 in exchange, and then this mold M is transferred to the cooled product conveyance line 6. being pushed out.

The mold M cooled by the cooling lines 5 and 6 is conveyed to the cooling drum 8 by the cooled product conveyance line 6.

At this time, since information on the mold M that has reached just before the cooling drum 8 can be known by the control computer C, the amount of water sprinkled on the cooling drum 8 is automatically determined based on the "ratio of casting amount and mold sand" of the mold M. Adjust.

Therefore, the optimum amount of water can be obtained. and,
Inside the cooling drum 8, the mold M is separated into mold sand and castings and discharged. Note that the cooled product conveyance line 6 is constituted by a roller conveyor or the like.

In the above embodiment, the control computer C learns information about the mold M at the pouring position 32 in the mold transport line T, the branch point 41 of the secondary cooling line, and just before the cooling drum 8, and based on this information, Although work has been carried out regarding the mold M, it is possible to obtain information about the mold M that has been shifted to any other address on the mold transport line T using an electronic computer.
