Each time 1,000 kg or I Ton is piled up, it must be carried out using a transport vehicle such as a forklift, and if the carrying out process is delayed, the above 2. The operation of the stacking equipment in the process must be stopped.

On the other hand, the continuous casting machine continues to produce aluminum ingots one after another, and it is absolutely impossible to stop this production, so the above 1. In the process, it is necessary to activate a safety device to discharge the aluminum ingots that have been aligned on the alignment conveyor.

The second object of the present invention is to avoid such a situation, and to avoid the above-mentioned 4. The purpose of the present invention is to provide a device capable of transferring and temporarily retaining aluminum ingots that have been stacked in the process.

Furthermore, the third object of the present invention is the above-mentioned 5. The purpose of this invention is to save the labor of transporting aluminum ingots by a transport vehicle such as a forklift in the process of 1, and to provide a device that can transport aluminum ingots that have been stacked on pallet ingots to a packing location by connecting a conveyor.

The present invention will be described below with reference to an embodiment shown in FIGS. 1 to 3.

1 is a chain conveyor, on which aluminum ingot A is placed.
Stack them up.

This stacking work is done in 2 above. As mentioned in the step above, stacking is performed using an automatic stacking device.

Reference numeral 2 denotes a top chain conveyor as a conveying device, which is linked with the chain conveyor 1 and conveys the aluminum ingot I-A transferred by the chain conveyor 1.

Reference numeral 3 denotes a hydraulic table lifter as a pushing up device, which is installed at the bottom of the top chain conveyor 2. On the table 3a of the table lifter 3, a fork 4 for pushing up the aluminum tip A is placed, and a fork 4 is placed on the table 3a of the table lifter 3. Then, on both needle sides of the top chain conveyor 2, a front and rear drive device for a fork 6 for lifting pallet ingots and a front and rear drive device for a pallet ingot pushing plate 7 are placed.

The pallet ingot fork 6 and push plate 7 are driven once by a cylinder 8 and a cylinder 9, respectively.

A storage 10 stores pallet ingots I-B stacked in a row, and is installed between the top chain conveyor 2, the pallet ingot fork 6, and the push plate 7.

In the embodiment of the device of the present invention configured as described above,
The series of operations described below can be automatically performed by a sequence control device including a detection switch such as a limit switch and a timer.

That is, when the aluminum ingots A stacked on the chain conveyor 1 are transferred by the top chain conveyor 2 and reach the upper part of the table lifter 3, the control device is activated by the detection switch provided on the top chain conveyor 2, and the top Chain conveyor 2 is stopped.

When the top chain conveyor 2 stops, the control device operates in response to the signal, drives the table lifter 3 to raise the table 3a, and pushes up the stacked aluminum ingots I-A with the fork 4 to the position shown in the fourth figure. That is, when the pallet ingot fork 6 rises from the lowest level of the storage 10 to the position where it reaches the bottom surface of the second pallet ingot, the table 3a sends a signal to the control device by the detection switch provided at that height, and the table 3a Stop the lifter 3.

When the table lifter 3 stops, the control device operates in response to the signal, drives the cylinder 8, advances the pallet ingot lifting fork 6, and inserts it into the lower surface of the second stage pallet ingot.

When the pallet ingot lifting fork 6 finishes moving forward, the control device operates in response to a signal from the detection switch, drives the table lifter 3 again to raise the table 3a, and the fork 4 lifts the stacked aluminum ingots A.
, the pallet ingot lifting fork 6 lifts the pallet ingots in the second and higher tiers, and when the push plate 7 rises to the position shown in Figure 5, that is, the position corresponding to the lowest pallet ingot, the table 3a A detection switch provided at that height sends a signal to the control device to stop the table lifter 3.

When the table lifter 3 stops, the control device operates in response to the signal, drives the cylinder 9, and the push plate 7 pushes the lowest pallet ingot onto the top chain 2, and then the push plate 7 returns to its original state. Return to position.

When the push plate 7 returns to its original position, the control device operates in response to the signal, drives the table lifter 3 to lower the table 3a, and moves the pallet ingot to the position shown in the third figure, that is, the second stage of pallet ingots. When the table 3a reaches the lowest position, a detection switch installed at that height sends a signal to the control device, stops the table lifter 3, and continues to drive the cylinder 8 to move the pallet ingot lifting fork. Move 6 back.

In this state, the stacked aluminum ingots A are placed on top chain conveyor 2 with pallet ingots interposed therebetween.

When the pallet ingot lifting fork 6 retreats, the control device is actuated by the signal, and the top chain conveyor 2 is moved one pitch to lift the aluminum ingot with the pallet ingot laid out on the lowest stage as shown in FIGS. 1 and 2.
The aluminum ingots are transferred to the left in the figure, and the next newly stacked aluminum ingot reaches the top of the table lifter 3, and the above operation is repeated.
