<Embodiment>

In the automatic hot water supply apparatus in the casting facility of the present invention, a mobile trolley is installed on a rail installed from the upper side of the melting furnace to the upper side of the thermal furnace of the die casting machine. Because of this, the hot water raised from the melting furnace by the shanghai-dong and oscillation of the ladle moves the rail up the die casting machine (near directly, not directly above it), and the ladle is moved horizontally by the operation of the actuator and the second drive source. Move to the die casting machine heatsink side (tilt), position it on the actuator and stop the ladle just above the die casting machine heatsink. Next, the second drive is activated, the ladle rotates slightly and the hot water in the ladle diecasts. It is automatically poured into the thermostat of the machine.

Next, embodiments of the present invention will be described based on the drawings.

1 is a side view of a mobile trolley equipped with a ladle according to an embodiment of the present invention. FIG. 2 is a front view of a mobile trolley equipped with a ladle according to an embodiment of the present invention. Fig. 4 is a partial plan view of the vicinity of the die casting machine of the automatic hot water supply device in the casting facility of the embodiment of the present invention.

The automatic hot water supply apparatus in the casting facility of the present invention shown in the drawing includes a rail 1, a moving trolley 2 having a first driving source 5 provided therein, and a support section 3 provided therein. It is operated by the ladle 4 which is operated by the arranged electric cylinder 6 and the 2nd drive source 7, the support body 3, the actuator for tilt | raise movement of the ladle, and the control member arrange | positioned at this. Control unit 27 for controlling the.

The rail 1 is specifically, for example, a running rail of an H-beam, and extends from the upper part of the heat retaining furnace 10 of the die casting machine 9 to the upper part of the melting furnace 11. If it is not possible to install the rails 1 directly above them, the rails 1 can be installed directly above them, but the ladle 4 is laterally transverse to the traveling direction of the moving cart 2 by the operation of the actuator 8. When inclined in the direction (front side), it is necessary to install the rail 1 so that the ladle 4 may be directly above the thermal path 10 (melting furnace 11 or).

On the rail 1, limit switches (control members) LS-1 to 6 which detect a signal when the moving cart 2 passes and give a signal to control the operation are disposed. Stops at the top of the melting furnace 11 or the heating furnace 10 for pouring or pouring the hot water.

The moving trolley 2 includes a pair of side plates 12 parallel to each other, and a bottom plate 13 which is set at the lower end of the side plate 12, and the bottom surface of the bottom plate 13 is a first driving source for driving. The motor 5 with a continuously variable transmission 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 trolley 2 by a belt, and from this interlocking gear 15 (both ends of the both ends). The outer circumferential surface of the traveling roller 16 is in contact with the inner surface of the bottom of the traveling rail, which is H-shaped. An electromagnetic brake (control member) is provided at one end of the shaft of the interlocking gear 15. 2 driven rollers 17 are arranged as shown in Figs. 1 and 2 so as to reach the bottom inner surface of the running rail so that the moving cart 2 can run stably.

An outer frame 18 is mounted and laid on the bottom plate 13 of the movable trolley 2, and a safety stopper 21 is disposed on the lower outer side thereof. The two support bars 3 parallel to each other provided are integrally provided. An electric cylinder 6 and a guide 19 are installed in the top frame and the bottom frame of the support bars 3.

Inside the guide 19, a slide bar 20 which is slidable in the vertical direction by the operation of the electric cylinder 6 is arranged. Ladles 4 (vertically arranged) connected to the lower end of the electric cylinder 6 are arranged at the lower end of the slide bar 20.

Therefore, the ladle 4 rotates (swings) little by little by the driving force transmitted from the motor, which is the second driving source 7, to the chain via the gear. A limit switch is arranged near the gear and the ladle 4 Control the fluctuation of the controller.

A support arm 23 protrudes from the bottom plate 13 of the moving trolley 2 and the other end of the actuator 8 having a hydraulic unit having one end at its protruding end is provided at the center of the support section 3. An actuator 8 having a hydraulic unit is arranged to receive and operate a position signal of the encoder 26 when the moving trolley 2 has moved upward of the heat path 10 of the die casting machine 9. .
Here, the encoder 26 is an encoder of the well-known technique used for automatic hot water supply apparatus in a casting facility, and this encoder 26 controls the operation position of the actuator 8 using its position signal.

Next, the specific operation of the automatic hot water supply device in this casting facility will be described.

Since the electromagnetic brake of the mobile trolley 2 is operating when it is located in the standby position, the mobile trolley 2 and the ladle 4 attached to the lower end thereof are firmly stopped and fixed at the position.

In the heat retaining furnace 10 of the die casting machine 9, when a water level detecting device (control member, not shown) that detects the amount of water in the inside of the die casting machine 9 detects that the amount of water has decreased, the electromagnetic brake that receives this signal The operation is released and the first driving source (motor) 5 of the moving cart 2 is operated. The traveling roller 16 which is interlocked by the operation of the first driving source (motor) 5 rotates and moves. The bogie 2 is moved in the direction of the melting furnace 11. When the moved bogie 2 passes and the limit switch LS-5 is operated, the rotation speed of the first drive source (motor) 5 decreases so that the bogie moves. (2) is decelerated, and when the limit switch LS-6 is operated, the first drive source (motor) 5 stops, so the moving cart 2 stops at that position and is firmly fixed by the action of the electromagnetic brake. .

In this way, after the moving cart 2 stops, the second drive source (motor) 7 is operated to rotate the ladle 4 by a predetermined angle. The motor is moved in a state in which the ladle 4 is rotated (beveled). The cylinder 6 is activated and the supporting rod 3 starts to descend with the ladle 4. The descending distance of the supporting rod 3 is the melting furnace 11 by means of a floating probe 22 disposed at the lower end thereof. The amount of hot water is measured and lowered until the ladle 4 reaches the distance set in the melting furnace 11.

Subsequently, the second driving source (motor) 7 is operated to inject the bath into the ladle 4 with the ladle 4 being rotated (tilted) in a horizontal state, and then the electric cylinder 6 is operated to operate the ladle 4. The support section 3 ascends with the wheels 4. Then, the first driving source (motor) 5 of the moving trolley 2 starts to rotate, and the moving trolley 2 is a die casting machine thermal furnace 10. In the direction of the limit switch LS-1, LS-2 located above and slightly ahead of the die-casting machine 9 that emits the signal after the limit switch LS-5 is operated. LS-2 After the operation is performed, the speed is low, and the moving cart 2 stops at the time when the limit switch LS-1 is operated, and the electromagnetic brake is actuated and securely fixed. The moving cart 2 is kept warm by the die casting machine 9. Actuator (8) with hydraulic unit receiving signal after stopping and fixing near upper part of (10) operates and at the same time The second drive source (motor) 7, which has been called, is operated, and by the actuator 8, the supporting section 3 is stretched and inclined toward the die casting machine heat path side so that the ladle 4 is moved by the position signal of the encoder. The ladle 4 is rotated little by little in accordance with the inclination of the supporting section 3 by the second driving source (motor) 7 but is always horizontal. After (4) stops just above the heat retaining furnace 10, the second drive source (motor) 7 is operated to rotate the ladle 4 by a predetermined angle, and the hot water in the ladle flows into the heat retaining furnace. When the pouring operation is completed, the second drive source (motor) 7 is operated so that the ladle 4 is returned to the horizontal state, and the actuator 8 is operated so that the support section 3 is vertical with the ladle 4. Next, the first driving source (motor) 5 is operated so that the moving cart 2 moves to its original standby position and stops. In Fig. 3 and Fig. 4, 24 is a stack of the die casting machine, and 25 is an accumulator.

Each of these operations is automatically controlled by the control unit by the control member arranged in the above devices.

In addition, when the die casting machine is placed under the running rail to pour water into each die casting machine heat path, the limit switches placed above the die casting machine other than the signaling die casting machine do not operate. Therefore, even if it touches them while the mobile truck is traveling, it does not give any signal, so hot water supply can be reliably performed only by the die casting machine with reduced water amount.

As described above, the present invention may or may not be a die casting machine in which an accumulator or a stack is installed in the vicinity of the heating furnace to prevent movement of the hot water, the hot water supply device, and the driving thereof. It is possible to provide a device which can supply a bath automatically from a melting furnace with a heat insulator and also supply it without accident because the bath cools down on the chute and no metal remains.
