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 dust or scum floating on the top surface of the molten metal and to cool the white metal mold.

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, if a plurality of ingots dropped from the chain conveyor are simply collected to form a single layer of ingots, and then stacked a certain number of stages to form a single layered mass of ingots, it is not only difficult to arrange and stack the ingots. The stacked mass may cause the load to collapse during transportation.

Therefore, in order to create a laminated mass of ingots that will not disintegrate even during bundling work and transportation by arranging and stacking the smallest ingots, four ingots are made into a set as shown in Figure 1 e. The ingot layer arrangement is formed by arranging two rows of ingots in the longitudinal direction (hereinafter referred to as the A-type arrangement), and the ingot layer arrangement of four ingots arranged parallel to the longitudinal direction as shown in Figure 1 f. A method was devised in which two types of ingot layers are alternately stacked: an array of ingot layers arranged one in the front and the other in the longitudinal direction and in the direction perpendicular to the ingot layer (hereinafter referred to as a B-type array).

Traditionally, ingots like this have been arranged manually, but various research has been carried out to automatically do this with machines, but when using machines, gaps inevitably occur between the ingots during arrangement, and it is difficult to arrange the ingots properly. I couldn't predict the result.

In particular, when transporting stacked blocks of ingots or loading and unloading them onto vehicles, transport machines such as forklifts are usually used. Therefore, it is necessary to place an ingot with legs as shown in FIGS. 1a and 1b on the bottom row with the legs facing downward, and to stack flat ingots on top of it.

Therefore, in order to bind the stacked ingots, it is necessary to arrange two types of ingots, flat ingots and legged ingots, into the two types A-type and B-type.

However, in order to stack ingots by machine, it is necessary to stack the ingots at a speed commensurate with the casting speed of the ingots by the casting machine, and if the ingot stacking speed is slower than the ingot casting speed, the ingot casting This may also lead to a decline in the ability itself.

Therefore, a need has arisen to improve a method and apparatus that can automatically arrange and stack ingots at a speed commensurate with casting capacity.

In addition, there were problems such as load collapse due to gaps being created between the ingots when the ingots were arranged.

The purpose of the present invention is to provide a method and device for arranging and stacking ingots that improves the overall casting ability and reduces the amount of material dislocation. A process of transferring the ingot from a mold of a fixed shape provided on the chain conveyor of the machine onto the main conveyance path, and conveying the ingot along the main conveyance path so that the longitudinal direction of the ingot is the same as the conveyance direction of the main conveyance path. If a set of four ingots each has legs, a rotating box that rotates so that the side with legs faces down, and two of the four ingots that are lined up next to each other. a step of alternately distributing and moving every other ingot toward a table that rotates 90 degrees; a step of moving one of the two ingots rotated on the table in the longitudinal direction to rearrange the front and rear positions; a step of alternately stacking the four ingot sets that have passed through the rotary box and the four ingot sets after completing the recombination process on an unloading conveyor; Alternately stack ingots formed in two rows in the longitudinal direction, and another set of ingots arranged perpendicular to the longitudinal direction, one in front and behind the four ingots arranged parallel to the longitudinal direction. In addition, a main conveyance path was installed below a chain conveyor equipped with two rows of molds of a certain shape, and the ingots delivered from the molds were placed two by two in parallel so that their longitudinal direction was parallel to the main conveyance path. The ingots are transported on the main transport path in the same direction as the transport direction, and by reciprocating across the end of the main transport path, sets of four ingots are alternately transferred from the main transport path in a direction perpendicular to the main transport path. A rotating box that is provided with an extrusion plate on the main conveyance path, and rotates so that the legged part is positioned downward when the ingots of the four-piece set are conveyed by the forward movement of the extrusion plate. is attached to one left or right side of the end portion of the main conveyance path, and a sub conveyance path is provided with a table that rotates 90 degrees the front two of the four ingots that are conveyed by the backward movement of the extrusion plate. installed parallel to the other side of the end of the main conveyance path,
a first plane plate that supports one of the ingots rotated by 90 degrees on the table and retracts it in the vertical direction from the surface of the sub-conveyance path, and the other three ingots are placed under the retraction of the first plane plate; A shaping box having a second flat plate serving as a conveying surface is installed vertically movably in front of the table on the sub-transfer path, and the shaping box is moved after the three ingots have passed through the second flat plate. The first flat plate and the conveying surface are aligned, and four ingots are arranged in the front and back of the ingots arranged in the longitudinal direction in a direction perpendicular to the longitudinal direction. The four ingots from the sub-conveying path are alternately conveyed onto the conveyor, and one set of ingots formed by arranging four ingots in two rows in the longitudinal direction and one set of four ingots are formed by arranging four ingots in two rows in the longitudinal direction. 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 ingot before and after the ingots arranged in parallel to the longitudinal direction.

Next, one embodiment of the present invention is shown in FIGS. 2 to 7, and this embodiment will be described in detail based on these drawings.

As shown in Fig. 4, a large number of molds 2 are fixed to a chain conveyor 1 so that two ingots are formed in two rows in the horizontal direction, and a main conveyance path 3 is installed below the chain conveyor 1. has been done.

At the rear end of the chain conveyor 1, the ingot is separated from the mold 2 by a hammer or the like and dropped onto the main conveyance path 3.The upper part of the rear end of the ingot is in contact with the mold 2 as shown in FIG. Accordingly, the ingot is pushed by the mold 2 and transported forward on the main transport path 3.

A first extrusion cylinder a having a claw plate (first extrusion plate) 4 attached to the tip of a piston rod 5 is installed on the main conveyance path 3 .

The claw plate 4 reciprocates a certain distance on the main conveyance path 3 by driving the first extrusion cylinder a, and conveys the ingots, which are conveyed in two rows on the main conveyance path 3, forward in groups of four.

The claw plate 4 can only swing forward and upward, and when the claw plate 4 transports the ingot a certain distance by driving the first extrusion cylinder a and then retreats, the claw plate 4 moves forward on the main conveyance path 3. When it hits an ingot, the claw plate 4 is pushed forward and upward and moved backwards following the shape of the ingot, and is directed to the rear ends of the next four ingots to be transported.

At the end of the main conveyance path 3, a second extrusion cylinder b is provided which has a second extrusion plate 6 at the tip of the piston rod I that reciprocates across the main conveyance path 3 at right angles.

The four-piece ingots that are continuously conveyed to the terminal end of the main conveyance path 3 by the driving of the first extrusion cylinder a are transferred to the main ingot by the forward movement of the second extrusion plate 6 by the drive of the second extrusion cylinder b. At the end side of the conveyance path 3 and at the second extrusion plate 6
The ingot is transported to the rotation box 9 of the ingot rotation device 8 installed in the direction of movement of the ingot, and the second extrusion plate 6 moves back to the sub-conveyor which is installed parallel to the main conveyance path 3 at the end of the main conveyance path 3. It is conveyed on the road 10.

That is, the second extrusion plate 6 is connected to the rotary box 9 and the sub-conveyance path 1.
It works to sort the ingots into 0 and 0.

The ingot rotating device 8 rotates the legged ingot by 180 degrees so that the leg of the legged ingot that is dropped from the mold 2 is oriented upward so that the leg is oriented downward.

As shown in Fig. 6-7, the ingot rotating device 8 has a rotating box 9 which is open at the front and back and has a stop plate 11 at the bottom of the rear end, supported by shafts 14 and 15 from both side walls 12 and 13, and the shaft 14 is used for the rotating box. The rotary box 9 is connected to the drive shaft of the actuator C, and the rotary box 9 is rotated 180 degrees by driving the rotary box actuator C.

This ingot rotating device 8 operates only for the legged ingots that are the lowest layer of the stacked mass formed by stacking an even number of stages (12 stages in this embodiment) by changing the arrangement for each stage, and the legged ingot layer The A-shaped flat plate ingot layer stacked on top does not need to be rotated 180 degrees, so it is 18
The rotating box 9 has rotated 0 degrees and the stop plate 11 is on the upper side.
pass through the inside.

When stacking 12 layers to form one stacked ingot block, when the 11th layer from the bottom (second layer from the top) of A-shaped child plate ingot layers passes through the rotary box 9, the rotary box actuator Iter C drives again and rotates the rotating box 9 by 180 degrees.
The ingot is rotated once to return to its original state, and then transported to prepare for the legged ingot that will become the bottom layer of the next stacked mass.

A communicating path 16 is installed in the slot in the rotating box 9 in the forward direction of the ingot, parallel to the main transport path 3.

A side plate 17 is provided at the side end of the communication path 16 to stop and align the ingots conveyed through the rotating box 9.

A third extrusion cylinder d is installed at the rear end of the communication passage 16 and has a third extrusion plate 18 at the tip of the piston rod 19 that reciprocates a certain distance on the communication passage 16 along the side plate 17 .

An unloading conveyance path 20 is installed on the forward direction side of the third extrusion plate 18 in a direction perpendicular to the main conveyance path 3, and the third extrusion plate 18 conveys the ingot by driving the third extrusion cylinder d. Then, the ingot is transferred onto the carry-out conveyance path 20.

A fourth extrusion cylinder j is installed on the unloading conveyance path 20, and is equipped with a fourth extrusion plate 22 at the tip of a piston rod 23, which pushes the ingots transferred by the third extrusion plate 18 into the piling case 21. .

The advancing direction of the fifth pushing plate 36 is the same as the advancing direction of the third pushing plate 18.

The extension of the sub conveyance path 10 communicates with the discharge conveyance path 20 installed at right angles to the main conveyance path 3, and the material is conveyed by the forward movement of the fifth extrusion plate 36 driven by the fifth extrusion cylinder h. The ingots are transferred onto the terminal end of the unloading conveyance path 20.

A shaping box 38 is installed on the carry-out conveyance path 20 and on the front sub-conveyance path 10 of the table 33.

This shaping box 38 has a first flat plate 39 on which only one cutting edge ingot is mounted, which is rotated 90 degrees by the table 33 and transported, and passes through the shaping box 38 when the shaping box 38 is raised. The second plane plate 40, which serves as a conveyance surface for the ingots to be conveyed, is formed as a bottom plate.

A sub-conveyance path equipped with a table that rotates 0 degrees is installed parallel to the other side of the end of the main transfer path, and the table supports one ingot that has been rotated 90 degrees and transports it from the surface of the sub-conveyance path. a first plane plate that is retracted in the vertical direction;
A shaping box having a second flat plate which serves as a transport surface for the other three ingots under the recess of the flat plate is installed vertically movably in front of the table in the sub-transport path, so that the three ingots are transferred to the second flat plate. After passing through the flat plate, move the shaping box so that the conveyance surface is aligned with the first flat plate, and place four ingots, one each in front and rear of the ingots arranged in the longitudinal direction, in a direction perpendicular to the longitudinal direction. Then, the four-piece ingots after passing through the rotary box and the four-piece ingots from the sub-conveying path are alternately conveyed onto the conveyor, and the four ingots are arranged in two rows in the longitudinal direction. One set of formed ingots and another set of ingots arranged in a direction perpendicular to the longitudinal direction, one ingot before and after the ingots arranged parallel to the longitudinal direction among the four ingots, are stacked alternately. An ingot array stacking device featuring:
