If you shift the mold by checking the ranking of the mold that is currently being recorded,
Since these molds are arranged in a fixed order, the recording device allows information on molds located at other addresses on the mold transport line to be known.

Further, if a specific mold position confirmation means is installed on the mold conveyance line, and information of a mold located at at least one address on the mold conveyance line is known by the mold position confirmation means, the mold It is also possible to know information about molds located at other addresses on the conveyance line.

Note that it is possible to provide information to the mold even during the mold conveyance line.

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

In the figure, T is a mold conveyance line, and upper mold conveyance line 1. Lower die transport line 2, 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 about the mold (pouring amount, amount of pouring, amount of additives, necessity of annealing time, ratio of pouring amount and mold sand) etc.) are sequentially recorded in an electronic computer (corresponding to the "recording device" of this invention). For this reason, the mold currently being produced (
If the information on the upper mold and the lower mold is known, the information on the mold M at any other address on the mold transport line T can be known by the computer. The upper mold 111 manufactured by the upper mold molding machine 11 is transported by the upper mold conveying line 1,
The lower mold 211 manufactured by the lower mold molding 621 is transported by the lower mold conveying line 2 to the position 1 of the weight on the trolley line 3.
．． 31. Note that a roller conveyor is suitable for both the upper mold conveying line 1 and the lower mold 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, the information on the mold M that has been shifted to the pouring position 32 can be confirmed by a computer, so the amount of poured metal, the amount of poured metal, and the presence or absence of additives are automatically determined according to the information on the mold M, and then the poured metal is poured. Ru. 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 (
"Sand mold with built-in casting" (the same applies hereinafter) M frame 7 is removed,
The mold M is extruded into a 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. In addition, the empty trolley is sent via trolley line 3.
The weight is shifted in the direction of position 31.

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 confirmed by a computer, the mold M is automatically transferred to either the cooled product conveyance line 6 or the secondary cooling line 5 according to the information. 5 will be selected. In other words, the information about the mold M is “
Those that have "need for annealing line" are pushed out to the secondary cooling line 5, and those 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 secondary cooling line 4 in exchange, and then this mold M is transferred to the cooled product conveyance line 6. is pushed out.

The cooled mold M is transported to a cooling drum 8 by a cooled product transport line 6. At this time, coolif drum 8
Since the information on the mold M that has been reached immediately before can be confirmed by an electronic computer, the amount of water sprinkled in the cooling drum 8 is automatically adjusted according to the "ratio of casting amount to mold sand" of the mold M. Therefore, the optimum amount of water can be obtained. Then, within the cooling drum 8, the mold M is separated into mold sand and a cast product and discharged. Note that the cooled product conveyance line 6 is constituted by a roller conveyor or the like.

In the above embodiment, the information about the mold M is obtained by a computer at the pouring position 32 in the mold transport line T, the branch point 41 of the secondary cooling line, and immediately before the cooling drum 8, and the information about the mold M is determined based on this information. Mold M
However, 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.

Further, in this embodiment, the mold position confirmation means was not provided in the middle of the mold conveyance line T, but such confirmation means were installed at appropriate positions and shifted to any address on the mold conveyance line T. If the code of the mold M is confirmed, since the molds M are arranged in a fixed order, the information of the mold M shifted to all other addresses can be known by an electronic computer.

〔Effect of the invention〕

The mold position confirmation device for a mold conveyance line according to the present invention includes:
Continuous addresses are set at regular intervals on the mold conveyance line,
The mold is shifted along that address.

It is also possible to set consecutive addresses on the mold transport line at regular intervals, shift the molds along the addresses, and provide a mold position confirmation means on the mold transport line.

Therefore, if codes and information are recorded in a required recording device (for example, a computer) corresponding to the mold, and then this mold is shifted along the mold conveyance line, the mold being recorded at the present time will be If the order of these molds is known, since these molds are arranged in a fixed order, it is possible to know information about molds located at other addresses on the mold transport line using the recording device.

Further, if a specific mold position confirmation means is installed in the mold transport line, and the mold located at at least one address on the mold transport line is known by the mold position verification means, the mold transport It is also possible to know information about molds located at other addresses on the line.
