In FIG. 1, T is a mold transfer line, which is an upper die transfer line 1, a lower die transfer line 2, a series of bogie lines 3, a primary cooling line 4, a secondary cooling line 5, and a cooled product transfer line. 6. Addresses 1 to 322 are virtually defined on the mold transfer line T, and the mold M shifts on these addresses. A control computer C manages various operations together with the virtual address of the mold transfer line T. The control computer C includes, for example, (1). The time required for each operation (for example, an operation of scooping hot water, an operation of moving a ladle, an operation of pouring water, etc.) in a pouring operation of a pouring robot (not shown),
(2). The relationship between the weight ratio of the foundry sand to the casting in the mold M (hereinafter referred to as “sand metal ratio”) and the amount of water sprayed on the cooling drum is input as a comparison value.

Next, the mold transfer line T will be described in detail.

Reference numeral 11 denotes an upper mold making machine, 21 denotes a lower mold making machine, and an upper mold 111 or a lower mold 211 functioning as a mold M.
To manufacture. 2 and 3 show the upper molding machine 11. FIG. In these figures, reference numeral 91 denotes a frame-shaped carrier, and 92 denotes a base of the carrier 91.
Reference numeral 93 denotes a window, which is formed in the carrier 91. Reference numeral 94 denotes a pattern plate which is fitted and fastened to the carrier 91 while being mounted on the base 92. This pattern plate 94 fixes a model 941. Reference numeral 942 denotes a protrusion, and the pattern plate 94
It is integrally molded on the side surface. The protrusion 942 is fitted in the window 93 of the carrier 91. 943,9
Reference numerals 43,... Are iron pieces corresponding to the information display means of the present invention. The iron piece 943 indicates the number of the iron pieces and the state of the iron pieces 943 indicating the information of the cast product of the mold corresponding to the model. Reference numerals 944 and 944 denote limit switches corresponding to the reading means of the present invention.
It is installed in. These limit switches 944, 94
By detecting the number and state of installation of the iron pieces 943 and 943 according to 4, information on a mold corresponding to the model (“information on a casting product to be cast by the mold”, the same applies hereinafter), for example, The type of hot water, the amount of hot water, the amount of additives, the necessity of an annealing line, the ratio of the casting amount to the mold sand, etc. are sequentially instructed and recorded in the control computer C. In the upper mold making machine 11, an upper mold (mold) 111 is formed by filling a molding frame 95 with molding sand. In addition, also in the case where it is provided in the lower molding machine 21, the information of the mold corresponding to the model can be instructed and recorded in the control computer C similarly to the upper molding machine 11. Either one may be sufficient. Therefore, if the information on the molds (upper and lower molds) currently being molded is known, the virtual address can be determined by the control computer C, so that information on the mold M at any other position on the mold transport line T can be obtained. You can know. Returning to FIG. 1, the description will be continued. The upper mold 111 manufactured by the upper mold making machine 11 is placed on the upper mold transfer line 1, and the lower mold 211 made by the lower mold making machine 21 is placed on the bogie line 3 by the lower mold transfer line 2. It is transported to the position 31. Both the upper die transfer line 1 and the lower die transfer line 2 are suitably roller conveyors.

Next, the bogie line 3 is composed of bogies connected at regular intervals. The upper mold 111 and the lower mold 211 are placed on a bogie as a mold M while aligning the frame at the position 31 where the weight is placed. The mold M moves in the direction of the arrow with the movement of the truck, and reaches the pouring position 32. At this time, since the information of the mold M shifted to the pouring position 32 can be known by confirming the virtual address by the control computer C, the information is automatically obtained according to the information of the mold M.
Pouring is performed after judging the type of pouring, the amount of pouring, and the presence or absence of additives. At this time, the start time and the end time of each operation (in a series of operations) in the pouring operation are also input to the control computer C, and the time required for each operation is measured by subtraction. The measured value is compared with a comparison value of the control computer C (the time required for each operation input in advance), and it is determined whether the measured value of each operation is included in the range of the comparison value. I do. When there is an abnormality in the pouring robot, that is, when the actual measured value of a certain operation in the pouring robot is out of the range of the comparison value, the control computer C sets "the actual measured value of any operation to the comparative value. Is not included "as an electric signal. For this reason, the manager can easily determine which operation of the pouring robot has failed in the remote position. The mold M after pouring shifts in the direction of the arrow along the bogie line 3 while being naturally cooled. Then, when it reaches the position 33, the frame 7 of the mold (referred to as "sand mold with built-in casting", the same applies hereinafter) M is removed, and the mold M is cooled by the primary cooling line 4 (consisting of a roller conveyor). ). Then, the empty frame 7 is appropriately conveyed by the conveyor 71 in the direction of the molding machines 11 and 21. In addition, the emptied bogie shifts through the bogie line 3 in the direction of the weight placing position 31.

The mold M that has entered the primary cooling line 4 reaches the branch point 41 at the end of the primary cooling line 4 while shifting the primary cooling line 4. At this time, since the information of the mold M shifted to the branch point 41 can be confirmed by the control computer C, the mold M is automatically sent to any one of the cooling product transport line 6 and the secondary cooling line 5 according to the information. Lines 6 and 5 will be selected. That is, those having the “necessity of an annealing line” as the information of the mold M are extruded to the secondary cooling line 5, and those having no such information are extruded to the cooling product transport line 6. It is. When the mold M is extruded into the secondary cooling line 5, the cooled mold M is extruded from the secondary cooling line 5 to the primary cooling line 4 instead. Extruded.

The mold M cooled by the cooling lines 5 and 6 is cooled by a cooling drum 8 by a cooled product transfer line 6.
Transported to At this time, since the information of the mold M reached just before the click drum 8 can be known by the control computer C, the sand metal ratio of the mold M is automatically compared with the comparison value of the control computer C. The control computer C controls the actuation of a water supply valve (not shown).
(Not shown). Then, the amount of water sprayed on the cooling drum 8 is adjusted to an optimum state. And
In the cooling drum 8, the mold M is separated into a mold sand and a casting and discharged. In addition, the cooling product transfer line 6 is constituted by a roller conveyor or the like.

In this embodiment, the case where the iron piece 943 is provided on the pattern plate 94 as the information display means has been described. However, the product information display means may be provided on the pattern carrier 91 similarly to the pattern plate 94. In this case, the pattern stored in the carrier 91
The content of the data 94 is displayed as information previously combined.
