The rail formed on the hollow line 100 of the present invention may be a two-rail type A in which the intermediate rail carriage 130 is raised and reciprocated and a middle rail carriage 130 is a monorail type B .

The main conveyor truck 130 of the present invention automatically feeds the core yarn through the chute 152 in the main hopper and then automatically moves the core yarn to the corresponding core yarn necessary for the core yarn to be automatically poured into the self- And the automatic control is performed by the control unit.

The core of the core which is supplied with the core yarn and which is used for manufacturing the core is manufactured by the automatic process. The core of the core is not only known in the prior art but also is a normal technology. will be.

Mainly four saddle bags loaded in the vehicle are transferred to the hoist 300 by the operator and are required in the main hopper 140.

The core yarn received in the main hopper is fed through the auto gate formed in the lower part of the main hopper and transferred to the intermediate conveyer carriage 150.

In the case of the present invention, various kinds of known technologies can be utilized. In the present invention, a large number of barges are formed on a caterpillar that moves up and down, and the core yarn is conveyed while the core yarn is conveyed. And then the upper part is taken up, and the molten metal goes down through the chute while falling downward, so that the heavy yarn is separated from the conveying hopper.

The chute 152 is opened when the carriage carriage reaches the correct position and the transfer carriage hopper is detected by the control unit, the carriage moves, the auto gate is opened, and the level sensor of the carriage hopper When the yarn is cooled, the related operation is stopped.

When the level sensor senses that the magnetic signature of the magnet is empty during the operation of the magnet manufacturing process, the magnet is moved to the main magnet and the magnetic sensor is detected until the level sensor of the magnetic hopper is detected It will give you a copy.

As described above, the present invention is configured so that the intermediate transfer yarn winding machine carries the intermediate yarn yarn and the intermediate yarn yarn is fed and supplied to the middle yarn hopper, which is needed automatically, while being automatically controlled by the control section.

The automatic supply system for heavy metal yarn according to the present invention is formed in such a manner that five or more hollow yarns are installed in a line form and a rail can be installed along a heavy magnetic line in a large heavy industry factory, The automatic feeder system automatically feeds the main hopper of the main hopper and feeds it to the hopper of a corresponding one of the necessary ones. It is possible to protect the user.

In addition, it has become possible to contribute to product quality, productivity, cost reduction, and the like by the automatic supply system of the present invention that the quality and productivity of the product have been deteriorated due to human work in the conventional bad condition.

In addition, the automatic supply system of the present invention has the effect of eliminating complaints caused by air pollution by achieving a comfortable working environment by collecting the harmful fumes by a dust collecting device composed of individual hoods, individual ducts, main ducts and dust collectors .

In addition, safety accidents have frequently occurred due to work in a conventional fountain. The automation of the manufacturing process of the present invention has the effect of significantly reducing safety accidents.
