Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ingot array stacking method and apparatus for automatically stacking metal ingots cast by a continuous automatic casting machine in a fixed array.

Recently, metal ingots, especially non-ferrous metals such as zinc, have come to be continuously cast using continuous casting machines, in which molten metal is injected into a number of molds fixed to a chain conveyor, and the metal is poured into the molds while being conveyed by the chain conveyor. In addition to removing dust or scum floating on the upper surface of the molten metal, the white metal mold is cooled.

A plurality of ingots cast in this manner are collected to form one layer of ingots, which are stacked in a certain number of stages and bundled, and the bundled ingots of a certain weight are shipped or transported to a warehouse.

However, simply collecting a plurality of ingots dropped from the chain conveyor to form one layer of ingots and stacking them a certain number of stages to form one ingot block (5 tack) not only makes the bundling work difficult. A lump of ingot may cause the load to crumble in the swinging towel.

Therefore, in order to create a mass of ingots that is likely to collapse even during bundling work and transportation through the minimum ingot arrangement process, four ingots are made into a set, and four ingots as shown in Figure 1e are each made into a set. Arrangement of molded ingots formed in two rows in the longitudinal direction (
(hereinafter referred to as an A-type arrangement) and an ingot arrangement (hereinafter referred to as an A-type arrangement) in which two of the four ingots are arranged parallel to the longitudinal direction as shown in Fig. A method was considered in which two types of arrays (referred to as type B arrays) were stacked alternately.

Conventionally, this kind of arrangement of ingots was done manually, but various studies have been conducted to automatically do this with machines, but when using machines, gaps inevitably occur between the ingots when they are arranged, and it is not enough. It was not possible to achieve a strong unity.

In particular, a transport machine such as a forklift is usually used to transport bundled ingots or to load and unload them onto a vehicle.In this case, it is difficult to use the transport machine when only flat plate ingots are stacked. Place an ingot with legs as shown in Figure 1 a and b on the bottom row with the legs facing downward, and stack flat ingots as shown in Figure 1 c and d on top of it. It is necessary to bundle as shown in Figure 1g and h.

Therefore, in order to bundle a mass of ingots, two types of ingots, flat ingots and legged ingots, must be arranged in the A-type arrangement and B-type arrangement, which makes it difficult to automate the bundling. there were.

Devices that use hydraulic or pneumatic cylinders to move the ingots horizontally or vertically to change the arrangement of the ingots have been developed to automatically arrange and stack ingots one by one using a machine, but the casting capacity of the casting machine is not sufficient. Despite the expected results, this conventional device requires a considerable stroke of the hydraulic cylinder to move the ingots in the stacking device, resulting in a decrease in time and efficiency. Casting automation ability commensurate with the fall will be reduced.

Furthermore, when the ingots are arranged, gaps are created between the ingots, causing problems such as load collapse.

The purpose of the present invention is to provide a method and device for arranging and stacking ingots that improve the overall casting capacity and reduce the amount of load dislocation.
