In FIG. 7, 62 is a stopper, which is a cylinder 63.
Thus, the cold material 7 transferred to the later-described charging box of the charging device 16 in the standing state as shown in the figure is prevented from being pulled out from the box while being mounted on the fork 55.

In the above-mentioned transfer device 15, when the cold material 7 is transferred by the lifter 20 and reaches its upper position, a transfer command signal is issued from the control device 6, whereby the transfer carriage at the standby position shown in FIG. The motor 40 drives the motor 43 to travel to the lifter 20 side. Then, the cold material 7 is scooped by the fork 44 and placed by the time the transfer truck 40 stops at the position where the lifter 20 is located. When the cold material 7 is received by the fork 44, the transfer carriage 40 travels to the original position and stops.
After that, the fork 44 is lowered to a position slightly lower than the conveyor 41 by driving the motor 47, and the cold material 7 is placed on the conveyor. After loading, transfer truck 40 is fork 44
Will be retracted to the position where it can be removed, and then the fork 44 will rise to the original position again and will wait until the next transfer of the cold material. After raising the fork 44, the conveyor 41 is driven, whereby the cold material 7 is further conveyed by the conveyor 41.
After the lifter 20 finishes receiving the cold material 7 by the fork 44, the carriage 40 starts traveling to the original position, then starts descending to reach the lower position and waits for the next cold material 7 to be transferred. become. The cold material 7 placed on the conveyor 41 is conveyed by the conveyor 41 to its front end. The cold material 7 that has reached the front end of the transfer conveyor 41 is moved to the front after the fork 55 of the transfer carriage 51 at the upper standby position in FIG. 8 is lowered to the bottom of the conveyor 41 by the motor 58. As it travels, it is scooped by the fork 55 and placed. Then, the loading device 51 is placed in the loading box of the loading device 16 which is on standby at a position facing the fork 55 and rotated by 90 ° toward the transport device 15 side. After the cold material 7 is put in the box, the transfer carriage 51 is moved to the rear with the original standby position, and the fork 55 is pulled out from the cold material 7. Further, the transportation status of the cold material 7 in the transfer carriage 40 or the like is input to the control device 6 as a presence signal / abnormality signal based on the warehousing / delivery management program.

The loading device 16 is a transfer device 15 as shown in FIGS.
It is equipped with a carrier truck 65 that receives the cold material 7 sent from the carrier to the copper converter 5, and this carrier truck 65 runs from the front end portion of the transport conveyor 41 on the rail 66 laid in the direction orthogonal thereto. You can run in the direction of the arrow. Carrier
Before and after the traveling direction of 65, input boxes 70, 71 of a size capable of accommodating the cold material 7 are rotatable on the supporting portions 68, 69, and a supporting shaft.
It is possible to tilt downward at a specified angle (for example, about 35 °) with 77 and 78 as fulcrums. It is possible to receive and store the cold material 7 from the transfer fork 55 through the openings 80 and 82 in a state where the boxes 70 and 71 are rotated 90 ° toward the transport conveyor 41 from the state of FIG. Further, the boxes 70 and 71 store the cold material 7 and then rotate again to return to the original state of FIG. 10, and the cold material 7 is conveyed in this state.

In the charging device 16 described above, the transfer device 15
When the transfer vehicle 51 of FIG. 9 is moved backward, a closing command signal is output from the control device 6 and the vehicle 67 is moved rightward or leftward in FIG. Converter 5
It is transported to near the side door 85 or 86. Then the side door
85 or 86 is opened through which the box 70 or 71 is placed in the hood of the copper converter 5. After that, the box 70 or 71 is tilted downward, and this tilt causes the box 70 or 71 to tilt.
The cold material 7 in 71 is put into the copper converter 5 from the box 70 or 71. After throwing in, the box 70 or 71 returns to the state before tilting, and the trolley 65 travels to the original position and returns, waiting for the next cold material 7. For each one-time input,
The input of the cold material 7 to the copper point furnace 5 is confirmed by a detector (not shown), and a signal for confirming the injection of the cold material 7 is input to the control device 6.
On the other hand, this charging operation is repeated until the specified charging amount is reached.

As described above, the arbitrary cold material 7 on the rail 10 of the cold material stock equipment 1 is identified by the control device 6 while identifying the type, number, weight, etc. of the automated guided vehicle 4, cold material. The transfer and charging device 3 is used to transfer and load the copper converter 5.

In addition, the cold stock equipment 1 in the embodiment,
It is needless to say that the stocking equipment 2 at the time of charging, the cooling material conveying and charging device 3 and the like are merely preferable examples, and that they may be designed other than those shown in the drawings when they are carried out.
