Abstract

PURPOSE:To reduce the manufacturing cost of a device by making the angular speed of a rotary table provided with a pouring funnel higher than the moving speed of a mold conveyor so that a driven table disposed on the rotary table has no driving device. CONSTITUTION:A rotary table 19 is turned at all times by a driving device 17 and a driven table 20 is moved in the same direction as the moving direction of a mold conveyor while said table is placed on the circular track 15 of the table 19. Since the angular speed of the table 19 is higher than the moving speed of the mold conveyor, a pouring funnel 23 moves together with the casting mold while the rollers 22 of the table 20 rotate by as much as the speed difference between both. When the front end of the pouring cup 28 of the funnel 23 moving together with the casting mold on the mold conveyor arrives right under a pouring device, the pouring device senses the arrival of the funnel 23 and the molten metal contained and weighed in one ladle of the pouring device is poured into the funnel.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pouring device, and more particularly to a circular pouring device suitable for pouring molten metal into molds on a continuously moving mold conveyor.

Casting equipment for manufacturing castings has recently become particularly larger and faster in order to improve quality and reduce costs. FIG. 1 shows a typical example of conventional equipment.

That is, the pouring ladle 4, which is composed of a hot water supply device 1, a circular pouring device 2, and a mold conveyor 6, and receives molten metal from the hot water supply device 1, runs on a circular rail 5, and
When approaching the mold 6 of the mold conveyor 5-1, the pouring ladle 4 and its driving device 7 run in synchronization with the speed of the mold conveyor 3 and pour the metal into the W1 mold 6. When pouring into the mold 6 is completed and the pouring ladle 4 separates from the mold conveyor 5, the driving device 7 for the pouring ladle 4 changes speed, and the hot water supply device 1
It travels at high speed until it stops and receives molten metal.

The pouring ladle 4 repeats the above-mentioned operation.

The five pouring ladles 4 running on the Tsumaji circular rail 5 are
Each drive device 7f: is provided. In this way, in order to provide each pouring ladle 4 with a drive device 7 that is synchronous or asynchronous with the mold conveyor 3, not only the drive device 7 but also various control devices are required. Not only does the production cost rise, but it also requires a lot of man-hours to maintain and manage the device, so it cannot be said to be a desirable device.

An object of the present invention is to provide an extremely economical circular pouring device that does not require a self-propelled drive device on the follower table equipped with a pouring funnel, and can run synchronously and asynchronously at high speed with a mold conveyor. .

Embodiments of the present invention will be explained in detail below with reference to all the drawings. FIG. 2 is a plan view, and FIG. 3 is an enlarged partial sectional view.

The present invention is a circular pouring device 12 for pouring molten metal into a mold 16 on a mold conveyor 13 that moves continuously. A rotary table 19 that rotates in the moving direction of the mold conveyor 13 is mounted on the rotary table 19, and a plurality of driven tables 20 with pouring funnels 25 mounted on the rotary table 19 can be moved relative to the rotary table 19. Install it like this. And driven base 2
0 is provided with a locking part 21 that engages with the concave mold 16, and the angular velocity of the rotary table 19 is made equal to the moving speed of the mold conveyor 15.

In addition, the pouring funnel 23 has a sprue 2 of the mold +6 below it.
4, and a melt receiving port 28 having a longitudinal opening in the direction of movement of the mold conveyor 13 above, and a structure in which the melt opening 27 and the receiving port 2B are communicated with each other. It is.

Next, the effects of the above configuration will be explained.

Since the rotary table 19 is constantly rotated by the drive device 17, the driven table 20 moves in the same direction as the mold conveyor +3 while being placed on the circular rail 15 of the rotary table 190. When the pouring funnel 25 mounted on the follower stand 20VC approaches the mold 16 placed on the mold conveyor 15, the locking member 21 engages with the concave mold 16.

Here, since the angular velocity of the rotary table 19 is faster than the moving speed of the mold conveyor 13, the pouring funnel 23 moves together with the mold +6 while the roller 22 of the driven table 20 rotates by the speed difference between the two. At this time, the tap hole 27 is adjusted by the locking member 21 so that it is located directly above the mold 16.

The pouring funnel 25il-I moves together with the mold 16 on the mold conveyor 13, and the front end 29 of the inlet 2B is connected to the hot water supply device 1.
1, the hot water supply device 11 senses the arrival of the pouring funnel 23, and the measured amount of molten metal stored in one ladle 31 of the hot water supply device 11 is poured. At this time, the pouring funnel 23 is moving together with the mold 16, but the ladle 51 of the water heater 11 is fixed, so that pouring of molten metal starts at the front end 29 of the molten metal receiving port 28 and ends at the rear end 5o. It has become.

When pouring into the mold 16 is completed, the hot water supply device 11 rotates around the shaft 32, and the other ladle 51' containing the measured molten metal waits on the mold conveyor 13 for the arrival of the mold 16. When the next mold 16 reaches the bottom of the ladle 51 together with the pouring funnel 23, pouring of molten metal begins at the front end 29 of the pouring spout 2B, and the pouring is completed at the rear end 30.

Mold conveyor + with mold 16 placed after pouring
3 shifts to a straight track, the locking member 21 of the driven base 20
is detached from the mold 16 and the driven table 20 with the pouring funnel 25 attached comes to rest on the rotary table 19, and is conveyed again to the vicinity of the concave mold 16 by the rotation of the rotary table 19.

By repeating the above operations, a plurality of driven stands 20
Molten metal is smoothly poured into a mold 16 placed on a continuously running mold conveyor 15 by a pouring funnel 25 attached to the mold conveyor 15.

The driven table 2o equipped with the pouring funnel 23 moves while being guided by the guide rails 26 of the rotary table 19 provided with a plurality of guide rollers 25.

Circular pouring device according to the invention: has many benefits! (It is about 1 km long, and the details will be described below.

(1) All of the plurality of slave nτυ tables disposed on the rotary table do not have a driving device, so that the cost for cultivating the buds 14 of the apparatus of the present invention is extremely low.

(2) During pouring, the driven table moves while the locking member is engaged with the mold, and when the locking member is released from the mold, it rotates together with the rotary table while remaining stationary on the rotary table.

Therefore, the structure is extremely simple.

(3) Since the driving 1υ source is only a drive device that rotates the rotary table completely, the energy saving effect is also significant.

(4) The pouring funnel attached to the follower table has an extremely simple structure.

(5) Since the device is circular, it occupies a small area, and since there is a large space in the center, maintenance and inspection of the device can be carried out easily and safely.

(6) The roller is rotating when the locking member holds the mold, or when the locking member is released, the rotation stops, so that sudden start of the driven vehicle can be suppressed.

In addition, in the above embodiment, the structure is such that it engages with the locking member kfJA type, but the structure is not limited to this, and it is also possible to achieve the entire turning purpose by having a structure that engages with a mold conveyor trolley, etc. Of course.

As is clear from the above description, the circular pouring device according to the present invention is a device for pouring metal into molds on a continuously moving mold conveyor, and has a novel structure that is completely unprecedented in conventional devices. Therefore, industrial VC can have a very large effect.
