The working process of the present invention is as follows: figure 1 , figure 2 As shown, in the initial state, the special forklift 5 is at the right extreme position, that is, at the leftmost aluminum ingot stacking position of the first-level finished product conveyor 3. Such as image 3 , Figure 4 , Figure 5 As shown, when the aluminum ingot stack 2 reaches the leftmost stack position of the first-level product conveyor 3, the system PLC controls the first-level product conveyor 3 to stop, the translation cylinder 54 extends, and drives the forklift body 20 to move forward to make the first The forklift arm 18 and the second forklift arm 23 extend directly below the aluminum ingot stack 2, and then the first lifting cylinder 13 and the second lifting cylinder 28 rise, driving the forklift frame 74 and the forklift body 20 around the third hinge 29 and The fourth hinge 44 rotates, so that the aluminum ingot stack 2 is separated from the leftmost stack position of the first-level finished product conveyor 3 and rises to the highest limit position. Next, the translation cylinder 54 retracts, driving the forklift body 20 and the aluminum ingot stack 2 to move back to the initial position, the first lifting cylinder 13 and the second lifting cylinder 28 descend, the first leg 45 and the second leg 61 The lower end surface of the aluminum plate falls on the upper surface of the first rectangular tube 67 of the translational vehicle body 42, and supports the weight of the aluminum ingot stack 2. After that, the system PLC controls the action of the servo motor 32 to drive the special forklift 5 and the aluminum ingot stack 2 to move to the left along the first track 6 and the second track 7 to the weighing position. The first lifting cylinder 13 and the second lifting cylinder 28 rise, the lower end surfaces of the first leg 45 and the second leg 61 are separated from the upper surface of the first rectangular tube 67 of the translation vehicle body 42, and the translation cylinder 54 extends The aluminum ingot stack 2 moves directly above the electronic scale 4, the first lifting cylinder 13 and the second lifting cylinder 28 descend, and the aluminum ingot stack 2 is placed on the electronic scale 4 smoothly. After the weighing is completed, the first lifting cylinder 13 and the second lifting cylinder 28 rise, so that the aluminum ingot stack 2 separates from the electronic scale 4, the translation cylinder 54 retracts, and the first lifting cylinder 13 and the second lifting cylinder 28 descends, and the lower end surfaces of the first leg 45 and the second leg 61 fall on the upper surface of the first rectangular tube 67 of the translation vehicle body 42. The system PLC controls the action of the servo motor 32, driving the special forklift 5 and the aluminum ingot stack 2 to continue to move to the left, reaching the rightmost stack position of the secondary product conveyor 1, and the first lifting cylinder 13 and the second lifting cylinder 28 rise After the translation cylinder 54 extends to move the aluminum ingot stack 2 directly above the rightmost stack position of the secondary product conveyor 1, the first lifting cylinder 13 and the second lifting cylinder 28 descend to place the aluminum ingot stack 2 on At the rightmost stack position of the secondary product conveyor 1, the translation cylinder 54 is retracted. Then the system PLC controls the secondary finished product conveyor 1 to move one stack to the left and then stops, while the servo motor 32 drives the special forklift 5 to the initial position, ready to transfer the next stack of aluminum ingots.
