BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manufacturing apparatus for continuously manufacturing a spherical (ball-shaped) ingot having a constant weight. The apparatus of the present invention is most suitable as an apparatus for manufacturing a ball-shaped ingot such as zinc or zinc alloy for plating.

[0002]

2. Description of the Related Art Conventionally, spherical ingots of metals such as zinc and copper and alloys thereof have been known. This spherical ingot is widely used in the past because, unlike the rectangular thick plate-shaped ingot, it can be rolled and conveyed, so that it can be easily put into a melting furnace of a plating tank or a die casting machine. . For the convenience of handling as a product, for example, the spherical ingot has a diameter of about 60 mm and a weight of about 610 to 620 g.

In the case of using such a ball-shaped ingot for use in a plating bath or the like, since the weight of each ingot is relatively large, the weight of each ingot must be constant to adjust the amount of dissolution. Desirably. Small metal particles can be adjusted to a constant weight as a whole even if the weight of individual particles is slightly different, but the difference in individual weight has a direct effect on relatively large ingots. become. However, almost no conventional ball-shaped ingot manufacturing apparatus has means for individually measuring the weight of the ingot.

And a sorting means 50 for the weighed spherical ingot 70. A normal weighing machine 30 can be used. As an example, a load cell is preferable in terms of operability, durability, installation space, and the like. If the load cell is provided with a weighing surface and is formed so as to come into indirect contact with the spherical ingot 70, even a high-temperature spherical ingot can be prevented from being affected by heat. The supply means 40 includes a storage chamber 41 that receives the spherical ingot 70 one by one,
A plurality of spherical ingots 70 are continuously arranged in a line from the casting part 10 while being rolled and guided to the accommodation chamber 41 continuously one by one, and the spherical ingots 70 guided to the accommodation chamber 41 are sequentially and continuously connected to a weighing scale.

According to the ingot manufacturing apparatus of the present invention,
Spherical ingots can be manufactured continuously. In particular, since a mechanism for continuously weighing spherical ingots one by one is provided, it is possible to mass-produce spherical ingots having a constant weight. Also, utilizing the fact that the outer shape is spherical, the load on the drive mechanism is small because the ingot is rolled and carried in and out at each part of the transport path and the weighing section,
In addition, since a series of operating speeds is high, manufacturing efficiency is good.
