Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for supplying and recovering a weir for attaching and detaching a weir used to guide the injection of molten metal from a ladle to a mold. It is about.

[0002]

2. Description of the Related Art Conventionally, when a mold is sent to a pouring position side by a ladle, an operator attaches a weir on the mold, and after the pouring, the worker removes the used weir from the mold again. ing.

[0003]

As described above, in the conventional method in which the work of attaching and removing the hanging weir to and from the mold is wholly dependent on manpower, the workability is extremely poor and the automatic pouring device It is not possible to make full use of the improvement in productivity due to the efficient casting that accompanies the introduction of. In particular, since the weir after pouring is heated and in a high temperature state, it is extremely dangerous to immediately remove it manually.

The present invention has been made in view of the above circumstances, and the work of attaching and removing the hanging weir to and from the mold can be performed automatically and labor-saving without depending on manpower, and productivity is improved while ensuring safety. It is an object of the present invention to provide a hanging weir supply / recovery device capable of achieving the above.

[0005]

In order to achieve the above object, the latch weir supply / recovery apparatus according to the present invention is such that a ladle with a latch attached at a predetermined set position of a mold transfer line is on standby. A mold supply device for sending the mold to a predetermined pouring position and returning the mold after pouring to the above-mentioned mold conveying line, and a hanging weir suspension arranged above the above-mentioned mold conveying line for suspending and carrying the hanging weir. A transfer device, a device for cleaning a weir used for pouring molten metal into the mold, and a device for cleaning the weir after it has been poured into the mold from the predetermined unloading side hanging position to clean the weir. A loading weir loading / unloading device for loading the loading weir to the loading side suspension position after cleaning to the processing equipment, and suspending the loading weir at the loading side suspension position and transporting it to the mold at the set position. And hook it on the mold that has returned to the set position after pouring. It is detached from the mold and conveyed to the hanging position on the unloading side and delivered to the hanging weir loading / unloading device. Installation and removal of weirs can be automated, labor can be saved, and after pouring,
It is possible to immediately remove the hanging weir in a high temperature state while ensuring safety, and it is possible to significantly improve the productivity in combination with automation.

Has been done.

Next, the operation of the apparatus having the above structure will be described. The ladle 2 that has received the molten metal travels through the self-propelled carriage 3 and is conveyed to a predetermined pouring position P, while the mold 5
Reaches a predetermined set position S, the latch weir suspension transfer device 9 moves to the loading side suspension position D2, and the extension of the piston rod 25a of the cylinder 25 causes the clamp portion 36, 36 to lower the hanging position D
The protrusions 8a, 8a on both ends of the hanging weir 8 after cleaning in 2 are engaged. Then, the piston rod 25a of the cylinder 25
The suspension base 26 is displaced upward due to the contraction, and the hanging weir 8 is suspended via the clamp portions 36, 36, and conveyed to a predetermined set position S. Then, when the piston rod 25a of the cylinder 25 is extended, the latch weir 8 is displaced downward, and is mounted on the mold 5 waiting at that position. After that, the transfer machine moves to a position where it does not interfere when the latch weir moves to the pouring position. At this time, the hanging base 2
The expansion of the piston rod 38a of the cylinder 38 in 6 causes the lid 40 to be displaced downwards and closes the opening of the weir 8 leaving the pouring portion, so that the splashing of the hot water during pouring is prevented.

The mold 5 to which the latch weir 8 is attached is sent to the pouring position P along the transfer line 4, where the molten metal from the ladle 2 is poured through the latch weir 8. After that, the mold 5 moves together with the weir 8 from the pouring position P to the setting position S.
Returned to.

When the casting mold 5 after pouring is returned to the set position S, the hanging weir suspending and conveying device 9 moves the hanging weir 8 on the casting mold 5 through the clamp portions 36, 36 in the same operation as described above. Since the hanging weir 8 is lifted, the hanging weir 8 is removed from the mold 5, and the casting mold 5 from which the hanging weir 8 is removed is sent to the subsequent process by the mold conveying line 4.

As described above, since the hanging weir 8 can be hung by the hanging weir suspending and conveying device 9 and automatically attached to the mold 5 before pouring, manpower can be saved and the work can be speeded up. it can. Further, even after the pouring, since the hanging weir 8 can be automatically removed from the mold 5 by the hanging weir suspending and conveying device 9, even if the hanging weir 8 heated at the time of pouring is in a high temperature state, it is safe. You can work.

The latch weir 8 removed from the mold 5 is transferred to the unloading side hanging position D1 by the latch weir suspending and conveying device 9 and transferred to the unloading portion 13A of the latch weir loading / unloading device 13. The latch weir 8 is sent from the hanging position D1 to the latch weir cleaning device 10 side, where it is held by the moving mechanism 12 and moved to the reversing device 11 to clean the inside of the latch weir on the reversing device 11. Then, the latch weir 8 uses the reversing device 11 to remove the molten metal and the like adhering to the bottom.

After the cleaning process, the latch weir 8 is held by the moving mechanism 12 and transferred to the loading section 13B of the latch weir loading / unloading device 13 and then moved to a predetermined loading side hanging position D2 by the loading section 13B. It is carried in and waits for the next mold 5.

[0018]

As described above, according to the present invention, it is possible to automate the work of attaching and removing the weir to and from the mold, and save labor, and eliminate dangerous work.
The working environment can be improved, and the productivity can be significantly improved in combination with automation.
