Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an ingot conveying device that can automatically convey ingot materials used in casting such as die casting.

The conventional ingot conveying device is disclosed in Japanese Patent Application Laid-Open No. 53-13783.
As shown in Publication No. 1, ingots are carried upward by an elevator-type parts feeder, rolled by their own weight in a linear main supply passage that slopes forward and downward, and are successively installed in this main supply passage. Ingots are supplied to each melting device through a plurality of branch passages.

In order to increase the efficiency of casting, it is necessary to install many melting furnaces, and it is desirable to increase the vertical height of the parts feeder and to increase the ingot transport speed by lengthening the main supply passage. There was a problem in that the vertical height of the building increased accordingly, requiring more vertical space within the building.

In addition, the lower the downstream side of the main supply passage, the greater the drop from the ingot discharge part of the parts feeder device, so the ingot conveyance speed increases accordingly, causing the ingot to roll too fast, increasing the noise from the main supply passage. There are problems such as the need to make the supply passage forming member high in strength. (1) It is difficult to time the distribution of ingots from the main supply passage to the branch passages, and there is also the disadvantage that the conveying posture of the ingots is easily disturbed.

The present invention was devised in view of the problems of the prior art described above, and its purpose is to reduce the vertical height of the device, and to control the conveyance conditions of the ingot, such as the rolling speed and conveyance posture of the ingot leading to each branch passage. An object of the present invention is to provide an ingot conveying device that can bring an ingot into a preferable state.

In order to achieve this object, the ingot conveying device according to the present invention includes a parts feeder device that supplies ingots, a main supply path that is inclined downward and guides the movement of ingots that are supplied from the parts feeder device. Two or more branch passages branched off from this main supply passage, a melting furnace provided on the discharge side of each branch passage, and a melting furnace provided at the inlet of the melting furnace to handle ingots supplied via the branch passage. A device comprising a preheating device for preheating and a supply control device for controlling the supply of ingots to the preheating device, and characterized in that the main supply passage is provided with an elevator device for lifting the ingots. It is.

Hereinafter, the present invention will be further explained according to an embodiment shown in the drawings.

The embodiment shown in FIG. 1 shows an example of a conveying device configured to automatically feed ingots, which have a ball shape and can be transferred by themselves, to a casting machine.

That is, the ingots 10 to be transported have a ball-like shape and are transported by the waisted transport vehicle 12, but in this embodiment, the ingots 10 transported by the transport vehicle 12 can be directly supplied to the storage location. That's how it's intended.

Therefore, as shown in FIG. 1, the conveyance vehicle 12 is moved onto an inclined table 14 whose top surface is inclined.
As illustrated, when the transport vehicle 12 is moved onto the slope 14 and the side door of the loading platform of the transport vehicle 12 is tilted down, the ingots 10 roll along the slope of the loading platform, and the lid 18 is opened. It falls into the basket 16 and is temporarily stored therein.

A ramp is provided at the bottom of the basket 16 for rolling the ingot 10, and the ingot 10 can be rolled along the ramp to the right as seen in FIG. 1 as shown.

In order to further roll the ingot 10 that has rolled from the basket 16, an elevator type parts feeder device 2 is provided.
This parts feeder device is provided in a vertical state, and the ingot 10 is lifted to a predetermined height by a conveyor (not shown) inside the parts feeder device.

The conveyor of this parts feeder 20 has a shelf for placing ingots that is tilted to the lower right as seen in FIG. When the ingot 10 reaches the inclined main supply passage 22 communicating with the main supply passage 22, it rolls out of the shelf of the conveyor by gravity in the direction of the main supply passage 22, and moves through the main supply passage 22 in the direction of the arrow in the figure. It will roll down like this.

This distribution member 36 is for distributing the ingot 10 sent through the main supply passage 22 to either the next main supply passage 22 or the branch passage 26, and is located at the position indicated by the two-dot chain line in FIG. When the ingot 10 is at the position indicated by the broken line, the ingot 10 is rolled to the side of the main supply passage 22, and when it is at the position indicated by the broken line, the ingot 10 is distributed to the side of the branch passage 26.

To operate this distribution member 36, the mounting flange 34
An actuating arm 38 is provided on the outside of the dispensing member 36 and operates in conjunction with the dispensing member 36.

This operating arm 38 rotates by a predetermined angle around a pin 36A which is the center of rotation of the distribution member 36, and its operating range is the range shown by the solid line position and the two-dot chain line position in FIG.

In order to actuate this actuating arm 38, the actuating arm 3
An actuating member 40 driven from an appropriate drive source (not shown) is connected to the connecting hole 38A provided near the tip of the actuating member 8, and a tension spring 42 for applying a tensile force in the opposite direction to the actuating member 40 is connected to the connecting hole 38A provided near the tip of the actuating member 8. Near the tip of the operating arm 38 and the mounting screw 42
It is stretched between A and A.

The actuation of the actuation arm 38 allows only one distribution member 36 to distribute the ingot 10 into either of the two passages 22 and 26.

Further, in order to control the supply of ingots 10 from the branch passage 26 to the preheating device 28, a supply control device 44 is provided near the entrance of the preheating device 28.

The details of this supply control device 44 are as shown in FIG.

As is clear from FIG. 3, the supply control device 44 has a mounting flange 46 fixed to the branch passage 26 at the entrance of the preheating device 28 near the lower end of the branch passage '26;
An operating arm 48 and a stopper 52 that is operated in conjunction with the operating arm 48 are attached to the mounting flange 46 on the pin 46.
It is attached so that it can rotate by a predetermined angle around 8A.

Therefore, the connecting hole 4 provided near the tip of the actuating arm 48

By operating the stopper 52 from the solid line position to the two-dot chain line position in the figure, the stopper 52 rotates in conjunction with the solid line position outside the branch passage 26 to the two-dot chain line position inside the branch passage 26. It is configured so that it can be closed.

This supply control device 44 supplies the ingot 1 to the preheating device 28.
By controlling the supply amount and supply speed of 0, the preheating temperature of the ingot 10 preheated by the preheating device 28 is controlled to a desired value, and a desired amount of the preheated ingot 10 is supplied to the casting machine 30, It becomes possible to maintain the amount of molten metal in the casting machine 30 constant.

The ingots 10 distributed to the main supply passage 22 on the downstream side by the distribution device 24 are further lifted diagonally by a predetermined amount by an elevator 54 provided on the downstream side,
Furthermore, it is supplied to the downstream distribution device 24, where it is again distributed to the main supply passage 22 and the branch passage 26, and the branch passage 26
The ingots 10 distributed to the side of the main supply passage 22 are supplied from the supply control device 44 to the next casting machine 30 via the preheating device 28, while the ingots 10 distributed to the side of the main supply passage 22 are further supplied to the subsequent elevator mold. The ingots IO that have not been carried into the casting machine 30 until the end are transported from the last end of the main supply passage to the opposite side of the main supply passage 22 as shown by the arrow in FIG. 1 (indicated by a broken line). It is returned to the parts feeder device 20 again through the return passage 56 which is inclined in the direction, and is further circulated.

Although the elevator 54 is not normally provided at the end of the main supply passage at the rearmost position, it is also possible to provide an elevator here to adjust the circulation rate of the ingot.

In this embodiment, in the conveying route of the ingot 10, from one main supply passage 22 to the next main supply passage 2
By providing an elevator 54 for lifting the ingot 10 on the way to the main supply passage 22, it is possible to prevent the ingot 10 from rolling down the main supply passage 22 too quickly due to acceleration, or from disturbing the conveying posture. , the ingots 10 always pass through the main feed passage 22 in the distribution device 2 at an optimal rolling speed and in a neat alignment.

Next, the operation of the conveying device of this embodiment will be systematically explained.

First, when the conveyance vehicle 12 loaded with ingots 10 is moved onto the slope 14 and the side doors of the loading platform of the conveyance vehicle 12 are tilted down, the ingots 10 roll down from the loading platform into the basket 16 along the slope of the loading platform. It is then stored once.

The ingots 10 in the basket 16 are transported along a ramp at the bottom of the basket 16 to an indoor elevator-type parts feeder 20.
The parts feeder 20 then lifts the parts feeder 20 to a predetermined height.

When the ingot 10 is lifted up to the position of the main supply passage 22 by the parts feeder device 20, the ingot 10
rolls out of the parts feeder 20 into the main supply passage 22 due to gravity and rolls down along the slope of the main supply passage 22.

When the ingot 10 rolls down to the position where the distribution device 24 is provided, the distribution member 36 of the distribution device 24
When in the dashed line position in the figure, the ingot 10 is distributed from the main supply passage 22 in the direction of the branch passage 26, from which it further rolls down to the supply control device 44, and is stopped by the stopper 52 of the supply control device 44. It is conveyed into the preheating device 28 while the amount is controlled, and the preheating device 28
Inside the casting machine 30, the ingot 10 is preheated by the heat of the combustion gas discharged from the casting machine 30 while rolling down along the spiral conveyance path, and the ingot 1 is preheated to a desired temperature.
0 is carried into the casting machine 30 in an amount controlled by the stopper 52 of the supply control device 44.

On the other hand, in the distribution device 24, the downstream main supply passage 22
After the ingot 10 distributed to the side is lifted to a predetermined height by the elevator 54 provided on the downstream side, it further rolls along the slope of the main supply passage 22, and is further transferred to the main supply by the downstream distribution device 24. Passage 22 or branch passage 2
It will be distributed among 6.

The ingots 10 that have not been distributed to the branch passage 26 to the end are returned to the parts feeder 30 via the return passage 56 and circulated there.

As explained above, according to the present invention, ingots can be completely supplied to the melting furnace automatically, making work extremely safe and efficient. It becomes possible to synergistically produce extremely good effects such as being able to effectively utilize the heat for preheating.

Furthermore, in the present invention, when distributing ingots to the main supply passage and the branch passage, the ingots can be distributed by a simple distributing device that uses only one distributing member, and the operation and structure are very simple. In addition to being easier,
