Description

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

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. The purpose is to remove dirt or scum floating on the top surface of the molten metal and to cool the gold layer in the mold.

A plurality of ingots cast in this manner are collected to form one ingot layer, 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 a single layer of ingots, and stacking them a certain number of stages to form one ingot block (laminated mass) would require an arrangement and stacking operation. Not only is this difficult, but the stacked blocks of ingots may become unbalanced during transportation.

Therefore, in order to arrange and stack the ingots using the minimum ingot arrangement and stacking process, and to create a stacked mass of ingots that will not collapse even if the ingots are pressed during transportation, four ingots are made into a set as shown in Figure 1e. An array of ingots formed by arranging four ingots in two rows in the longitudinal direction (hereinafter referred to as the A-type arrangement) and two of the four ingots arranged in parallel in the longitudinal direction as shown in Figure 1 f. A method has been devised in which two types of ingot layers are alternately stacked: an array of ingots arranged in the front and rear of the ingot in the direction perpendicular to the longitudinal direction (hereinafter referred to as a B-type arrangement).

Traditionally, ingots like this were arranged manually, but various studies have been conducted to automatically do this using machines, but when using machines, gaps inevitably occur between the ingots when they are arranged. We were not able to achieve sufficient 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. , Figure 1a on the bottom row.

It is necessary to place an ingot with legs as shown in b so that the legs are facing downward, and then stack flat ingots as shown in FIG.

Therefore, in order to make a laminated ingot block, two types of ingots, flat ingots and legged ingots, must be arranged in two types, the A-type arrangement and the B-type arrangement.

As a device for automatically arranging and stacking ingots using a machine, a device has been developed that moves the ingots horizontally or vertically using a fluid such as a hydraulic or pneumatic cylinder to change the arrangement of the ingots, but the casting capacity of the casting machine is limited. Despite its high expectations, this conventional device requires quite a lot of strokes from fluid cylinders, etc. to move the ingots into the ingot arrangement and stacking device, resulting in a decrease in time efficiency and the need for a chain that fixed the mold. The ability to stack ingots in an array commensurate with the dropping of ingots from the conveyor is 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 taken out from a casting machine, in order to improve the overall casting ability and to reduce the amount of ingots falling apart. A process of transferring the ingot from the mold to the main conveyor,
arranging the four ingots conveyed on the main conveyor in two rows so that the longitudinal direction thereof is parallel to the conveyance direction of the main conveyor, and the middle two ingots among the four ingots. The process of alternating the orientation of the ingots by 90 degrees and the process of assembling the ingots, and the process of placing the ingots in a rotating box that rotates so that the side with the legs faces down if each of the four transported ingots has legs. and a step of stacking the four ingots that have passed through the rotary box on a delivery conveyor, and one set of four ingots each formed by arranging two rows in the longitudinal direction. The ingots are alternately stacked with another set of four ingots arranged in parallel to the longitudinal direction, one ingot placed before and after the ingots in the direction perpendicular to the longitudinal direction, and two molds of a fixed shape are formed. A main conveyor for conveying the ingots dropped from the mold is installed below the end of the chain conveyor provided in the row, and four ingots are placed on the main conveyor with the longitudinal direction perpendicular to the conveying direction of the main conveyor. A first gripping chuck and a second gripping chuck are installed in the middle of the main conveyor, and the ingots to be conveyed are turned 90 degrees in the conveying direction of the main conveyor every other set and rearranged in two parallel rows. A two-grip chuck is used to change the direction of the middle two ingots of every other set by 90 degrees so that they are parallel to the conveying direction of the main conveyor, and a fluid cylinder or the like is used to turn the middle two ingots of every other set of ingots above the terminal end of the main conveyor. An extrusion plate that reciprocates across the main conveyor is attached to the terminal end of the main conveyor to move the ingots onto the carry-out conveyor, and an ingot rotating box is provided at an intermediate portion between the terminal end of the main conveyor and the carry-out conveyor. If the ingot transported by the ingot has legs, it is rotated so that the legged part is positioned downward, and a pair of ingots formed by arranging four ingots in two rows in the longitudinal direction, and a set of four ingots are formed. It is characterized in that the ingots arranged parallel to the longitudinal direction are alternately stacked with another set of ingots arranged perpendicular to the longitudinal direction, one before and after the ingots.
