The first lifting tray assembly 14 is fixedly connected to the first sliding block 13 of the first servo motor 12 through the first connecting plate 141. The system rotates the first servo motor 12 of the material box lifting device, and the first sliding block 13 runs in a straight line, with the first lifting tray assembly 14 to move up and down. The first lifting tray assembly 14 pushes the material box 4 to move up and down.

[0048] When it is necessary to extract the empty material box 4, it is driven by the transverse servo motor 3 of the transverse module, and the slider 20 runs linearly to drive the material box clamping mobile device to operate.

When the judgment result is valid, the first servo motor 12 drops to the set position, and the material box clamping mobile device completes the extraction action of the empty material box 4, and the material box 4 can be taken to the unloading station to receive the product that has been sealed;

[0049] When the material box 4 is full of material and needs to be replaced, the material box clamping moving device moves to the placement position above the second storage cavity 21, the second servo motor 22 of the material box lifting device rotates, and the second sliding block 23 drives the second lifting tray assembly 24 to rise, reaching the bottom of the material box clamping moving device to receive the material box 4; the first clamping cylinder 71 drives the first clamping plate 72, and the second clamping cylinder 74 drives the second clamping plate 75 to open, releasing the material box 4. After the first clamping device and the second clamping device complete the placement of the material box 4, the second servo motor 22 descends, and the full material box 4 is stored in the second storage cavity 21 of the material box lifting device, and the material box clamping moving device returns to the material box 4 extraction position, that is, the first storage cavity 11 to extract the new material box 4, thereby completing the operation process of the unloader automatically taking and placing the material box 4.

[0050] The innovation focus of the present invention lies in the mechanical structure and connection relationship. The equipment system controller controls the actions of the first servo motor 12, the second servo motor 22, the transverse servo motor 3, the first gripper cylinder 71, the second gripper cylinder 74, the first sensor 146, the second sensor 246 and the third sensor 15, as well as the corresponding electronic control system by writing programs and settings.
