Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an ingot conveying device that can automatically convey ingot materials used in casting such as die casting.

[Conventional technology]

The conventional ingot conveying device is
As shown in Publication No. 137831, ingots are temporarily stored in a basket, transported upward by an elevator type parts feeder, and rolled by their own weight in a single linear main supply passage that slopes forward and downward. Ingots are supplied to each melting device through a plurality of branch passages sequentially provided in this main supply passage. To carry the ingots into the basket, as shown in FIG. 1, the ingots 1 are carried by a truck and are carried into the basket 4 by a forklift 2. Furthermore, the bottom 4A of the basket 4 is flat, and the ingots 1 can be fed up to the parts feeder device 6.
In order to guide the basket 4, the entire basket 4 was vibrated by a vibration device (not shown).

[Problem that the invention attempts to solve]

However, in the conventional device, the ingots 1 in the basket 4 are not smoothly fed to the feeder device 6.
It was not possible to ensure continuous transportation of ingots.

In addition, 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 device and to increase the ingot transport speed by lengthening the main supply passage. As the vertical height of the equipment increases accordingly, more vertical space is required within the building.

Further, the higher the upstream side of the main supply passage, the greater the drop from the ingot discharge section of the parts feeder device, so the ingot conveyance speed increases accordingly, causing the ingot to roll too quickly. Therefore, the noise from the main supply passage increases, the main supply passage forming member must be made of high strength, and there are further problems such as difficulty in timing the distribution of ingots from the main supply passage to the branch passage. Moreover, there was also the drawback that the conveying posture of the ingots was easily disturbed. Conventionally, in order to carry ingots into a basket, as shown in FIG. 1, it was necessary to carry ingots 1 carried by a truck into a basket 4 by a forklift 2. Further, the bottom 4A of the basket 4 is flat, and in order to guide the ingots 1 to the parts feeder device 6, the entire basket 4 is vibrated by a vibrating device (not shown). There was a problem in that the ingots 1 were not smoothly fed to the feeder device 6, and therefore continuous conveyance of the ingots could not be ensured.

[Purpose of invention]

The present invention was devised in view of the problems of the prior art described above, and its purpose is to create a rolling type ingot that can optimally and continuously be fed from an ingot transport vehicle to each melting furnace by utilizing the rolling movement of the ingot due to its own weight. An object of the present invention is to provide a conveyance device.

[Means for solving problems]

In order to achieve the above object, the rolling ingot conveying device of the present invention is provided with an ingot conveying vehicle that can enter the ingot, and a ramp surface that allows the rolling ingot to be carried out by rolling under its own weight from the vehicle. and a ramp installed adjacent to the ramp to receive and temporarily store the ingots rolled and carried out from the ingot transport vehicle;
A basket having a downwardly sloping passage on the exit side, a parts feeder device that supplies ingots sent through the passage of the basket, and a downwardly sloping passageway that guides the rolling of the ingots fed from the parts feeder device. a main supply passage having a plurality of supply passages arranged on the upstream side, the rolling end of the supply passage installed on the upstream side being located lower than the rolling start end of the supply passage installed on the downstream side; an elevator device connecting each supply passage; a branch passage branching from the main supply passage and having a melting furnace disposed on the exit side; and a supply control provided in the branch passage for controlling the supply of ingots to the melting furnace. It consists of a device.

Details of the distribution device 24 are as shown in FIG. A branch pipe 32 is provided between the main supply passage 22 and the branch passage 26, and a mounting flange 34 is provided on the outside of the T-shaped portion of the branch pipe 32. A distribution member 36 is provided inside the branch portion of the branch pipe 32 and is rotatable by a predetermined angle around a pin 36A. This distribution member 36 is for distributing the ingots 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 shown in FIG. To actuate the distribution member 36, an actuation arm 38 is provided on the outside of the mounting flange 34 and operates in conjunction with the distribution 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 operate this actuating arm 38, an actuating member 40 driven from an appropriate drive source (not shown) is connected to a connecting hole 38A provided near the tip of the actuating arm 38, and is connected in the opposite direction to the actuating member 40. A tension spring 42 for applying a tensile force of 1 is tensioned between the vicinity of the tip of the actuating arm 38 and the mounting screw 42A. By actuation of the actuating arm 38, only one distribution member 36 is required 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. 4, the supply control device 44 is connected to the branch passage 26 at the entrance of the preheating device 28 near the lower end of the branch passage 26.

Therefore, an actuating member 50 that is actuated from an appropriate drive source (not shown) is connected to a connecting hole 48B provided near the tip of the actuating arm 48, and this actuating member 50 is moved from the solid line position in FIG. When the stopper 52 is actuated to this position, the stopper 52 is configured to rotate in conjunction with the solid line position outside the branch passage 26 to the double-dot chain line position inside the branch passage 26, thereby closing the branch passage 26. There is. With this supply control device 44, the preheating device 28
By controlling the supply amount and supply speed of the ingots 10 to the casting machine 30, a desired amount of preheated ingots 10 can be supplied to the casting machine 30 while the preheating temperature of the ingots 10 preheated by the preheating device 28 is controlled to a desired value. The amount of molten metal in the casting machine 30 can be maintained 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.
The ingots 10 are supplied to the main supply passage 22 and the branch passage 26 again, and the ingots 10 distributed to the branch passage 26 are supplied from the supply control device 44 to the next casting machine 30 via the preheating device 28. On the other hand, the ingots 10 distributed to the side of the main supply passage 22 are further sequentially conveyed via the elevator 54 at the later stage, and the ingots 10 that have not been carried into the casting machine 30 until the end are transferred to the main supply passage 22 as described above. The parts are returned to the parts feeder device 20 again through a return path 56 inclined in the opposite direction to be further circulated.

In this embodiment, in the conveyance route of the ingot 10, an elevator 54 for lifting the ingot 10 is provided at a position halfway from one main supply passage 22 to the next main supply passage 22, so that the main This distribution device prevents the ingots 10 rolling down the supply passage 22 from rolling too fast due to acceleration or from disrupting the conveying posture, and allows the ingots 10 to always move through the main supply passage 22 at an optimal rolling speed and in a properly aligned state. 24 can be ensured.

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 ingot 10 in the basket 16 is placed on the ramp 1 at its bottom.
