FIG. 1 is a side view of a mobile truck equipped with a ladle according to an embodiment of the present invention. FIG. 2 is a front view of a mobile truck equipped with a ladle according to an embodiment of the present invention. FIG. 3 is a layout view of a main part of an automatic water heater in a casting facility according to an embodiment of the present invention. FIG. 4 is a partial plan view of the vicinity of a die casting machine of an automatic water heater in a casting facility according to an embodiment of the present invention.

The automatic hot water supply device in the casting equipment of the present invention shown in the drawings includes a guide rail 1, a movable carriage 2 provided with a first drive source 5 installed on the guide rail 1, and a support rod 3 suspended on the movable carriage 2. A ladle 4 operated by an electric cylinder 6 and a second drive source 7 provided, a support rod and a hydraulic cylinder 8 for inclining the ladle, and a control unit for controlling the operation by a control member provided on these (shown in the figure. Omitted) and.

The guide rail 1 is, for example, specifically an H-shaped steel traveling rail, and is provided above the melting master furnace 11 and above the heat retaining furnace 10 of the die casting machine 9. When the guide rail 1 cannot be installed right above the melting parent furnace 11 and the heat-retaining furnace 10, the guide rail 1 can be placed in the upper vicinity as close as possible to just above these, but the operation of the hydraulic cylinder 8 causes the ladle 4 to move the moving carriage 2. It is necessary to set the guide rail 1 so that the ladle 4 is located directly above the melting master furnace 11 or the heat retaining furnace 10 when tilted laterally (front side) with respect to the direction. Further, the guide rail 1 is provided with limit switches (control members) LS-1 to LS-6 which immediately detect the passage of the moving carriage 2 and issue a signal for controlling the operation thereof. By this limit switch, the movable carriage 2 is stopped above the melting parent furnace 11 or the heat retaining furnace 10 which requires the pumping or pouring.

The movable carriage 2 includes a pair of side plates 12 that are parallel to each other and a bottom plate 13 fixed to the lower ends of the side plates 12. The bottom plate 13 has a lower surface on which a first traveling plate is mounted. A motor 5 with a continuously variable transmission, which is a drive source, is attached. The driving force of the motor 5 with the continuously variable transmission is transmitted from the drive shaft 14 to the shaft of the interlocking gear 15 of the moving carriage 2 by the belt, and further from the interlocking gear 15 (from the gears at both ends thereof) of the traveling roller. It is transmitted to 16. The outer peripheral surface of the traveling roller 16 is in contact with the inner surface of the bottom of the traveling rail having an H shape. An electromagnetic brake (control member, not shown) is provided at one end of the shaft of the interlocking gear 15. Two driven rollers 17 are arranged as shown in FIGS. 1 and 2 so that the movable carriage 2 can travel stably by contacting the inner surface of the bottom of the traveling rail.

An outer frame 18 is suspended and fixed to the bottom plate 13 of the movable carriage 2, and a safety stopper 21 is provided outside the lower part thereof. Inside the outer frame 18, two support rods 3 which are suspended from the movable carriage 2 and which are parallel to each other are integrally mounted on a shaft. An electric cylinder 6 and a guide 19 are fixedly mounted on the upper frame and the bottom frame of the support rod 3. Inside the guide 19, there is provided a slide bar 20 which can be slid vertically by the operation of the electric cylinder 6. On the lower end of the slide bar 20, a ladle 4 connected to the lower end of the electric cylinder 6 (is vertically installed) is pivotally attached at the lowest end. Therefore, the ladle 4 is rotated (swinged) little by little by the driving force transmitted from the motor, which is the second driving source 7, via the gear via the chain. A limit switch is provided near this gear, and the swing of the ladle 4 is controlled by the control unit. A support arm 23 is projectingly provided on the bottom plate 13 of the movable carriage 2, and the other end of a hydraulic cylinder 8 with a hydraulic unit, one end of which is axially mounted on the projecting end, is axially mounted in the middle of the supporting rod 3. There is. The hydraulic cylinder 8 with a hydraulic unit is provided with a device (control member, not shown) that operates in response to a signal emitted when the moving carriage 2 moves above the heat insulation furnace 10 of the die casting machine 9. Has been.

Next, a specific operation of the automatic water heater in this casting facility will be described. When the vehicle is in the standby position, the electromagnetic brake of the moving vehicle 2 is in operation, so that the moving vehicle 2 and the ladle 4 attached to the lower end of the moving vehicle 2 are securely stopped and held at that position.

When a hot water amount detecting device (control member, not shown) that detects the amount of hot water in the heat-retaining furnace 10 of the die casting machine 9 detects that the amount of hot water has decreased and issues a signal, this signal is output. The operation of the received electromagnetic brake is released and the first drive source (motor) 5 of the moving carriage 2 is operated. The operation of the first drive source (motor) 5 causes the traveling roller 16 that is interlocked to rotate, and moves the moving carriage 2 toward the melting master furnace 11. When the moved carriage 2 passes and the limit switch LS-5 operates, the rotation speed of the first drive source (motor) 5 decreases, the carriage 2 slows down, and the limit switch LS-6 operates. When this is done, the first drive source (motor) 5 is stopped, so that the moving carriage 2 is stopped at that position, and is reliably held by the action of the electromagnetic brake.

After the moving carriage 2 is stopped in this way, the second drive source (motor) 7 is activated and the ladle 4 is rotated by a predetermined angle. Then, the electric cylinder 6 operates while the ladle 4 remains rotated (inclined), and the support rod 3 starts to descend together with the ladle 4. As for the descending distance of the supporting rod 3, the amount of hot water in the melting master furnace 11 is measured by a hot water amount sensor 22 provided at the lower end thereof, and the ladle 4 descends until it reaches a set distance in the melting master furnace 11.

Next, the second drive source (motor) 7 is operated to bring the rotating (tilting) ladle 4 into a horizontal state, and after drawing hot water into the ladle 4, the electric cylinder 6 is operated to operate the ladle 4. The supporting rod 3 ascends together with 4. Then, the first drive source (motor) 5 of the moving carriage 2 starts to rotate, the moving carriage 2 moves toward the die casting machine heat-retaining furnace 10, and the limit switch LS-5 is actuated, and then the signal is issued. The limit switch LS-1 and LS-2 located above and slightly ahead of the die-casting machine 9 becomes the low speed after the LS-2 located nearer the limit switch LS-1 is activated, and the limit switch LS-1 The mobile carriage 2 is stopped when is activated, and the electromagnetic brake is activated to securely hold it. After the movable carriage 2 is stopped near and above the heat-retaining furnace 10 of the die casting machine 9, the hydraulic cylinder 8 with the hydraulic unit that receives the signal is activated and the second drive source (motor ) 7 is actuated, the hydraulic cylinder 8 pulls the support rod 3 toward the die-casting machine warming furnace side and inclines it so that the ladle 4 stops at a position just above the warming furnace 10. The drive source (motor) 7 of the above rotates little by little according to the inclination of the support rod 3 and is always in a horizontal state. After the ladle 4 is stopped just above the heat retaining furnace 10, the second drive source (motor) 7 is activated to rotate the ladle 4 by a predetermined angle, and the hot water in the ladle is poured into the heat retaining furnace. When the pouring work is completed, the second drive source (motor) 7 operates to return the ladle 4 to the horizontal state, and the hydraulic cylinder 8 operates to return the supporting rod 3 to the vertical state together with the ladle 4. Next, the first drive source (motor) 5 is activated to move the movable carriage 2 to the original standby position and stop it. 3 and 4, 24 is a stack of a die casting machine, and 25 is an accumulator. Each of these operations is automatically controlled by the control unit by the control member provided in each of the above devices.

When a plurality of die casting machines are located below the traveling rail and hot water is poured into each die casting machine heat insulation furnace, the die casting machines are provided above the die casting machines other than the signal emitting die casting machine. Since all the limit switches are inactive, even if they come into contact with them while the vehicle is running, no signal will be emitted, and therefore hot water can be reliably supplied only to the die casting machine with a reduced amount of hot water. It can be carried out.
