Therefore, the number of material boxes and empty material boxes that can be stacked is large, thereby increasing the capacity of the entire feeding system.

[0017] 2. Fast feeding speed: The fully automatic feeding system of the present invention is equipped with an empty material box stacking mechanism. After each box of material is taken, the empty material box will be immediately transferred to the empty material box stacking mechanism for stacking, and then the new material box will be clamped and replenished. The whole process can be completed within 4 seconds, and the feeding speed is fast.

[0018] 3.

Therefore, without stopping the feeding system, material boxes can be replenished at any time and empty material boxes that have been stacked can be taken away, which is very convenient for manual loading and unloading.

[0019] 4. Strong compatibility: The fully automatic rapid feeding system of the present invention is provided with a tray positioning block, which can locate the position of the material box and clamp the material box. It is compatible with material boxes of various sizes and has strong compatibility.

[0020] 5. Convenient material grabbing: The fully automatic rapid feeding system of the present invention is equipped with a material box positioning component. The material box on the tray will be positioned and clamped, ensuring that the material in the material box can be accurately and stably grabbed.

[0021] 6. Expandable: If space permits, the storage capacity of material boxes and empty material boxes can be expanded by extending the length of the lower roller line and the upper belt conveyor line to meet more storage needs.

[0022] 7. Good flexibility: Due to the design of the present invention, the manual removal of empty material boxes and the filling of material boxes are separated from the actions in the equipment, so that they do not affect each other and the equipment does not need to be stopped during manual operation. This makes the time for manual material box processing more flexible and reduces the downtime waiting time of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The structural diagram of the automatic material handling system in this embodiment when working is as follows Figure 6 shown.

[0038] The specific working process of the fully automatic feeding system in this embodiment is as follows:

[0039] When loading, the start button of the feeding system is triggered to put the stacked material boxes in. The stacked material boxes are transported to the end of the stroke by the roller conveyor line 202, triggering the micro switch 204. When the micro switch 204 is triggered, the electric cylinder 303 drives the clamping jaw 306 to move downward along the first linear guide rail 302. When the photoelectric sensor installed on the clamping jaw 306 detects that there is a material box in the clamping jaw 306, the electric cylinder 303 stops moving downward. At this time, the second telescopic cylinder 308 retracts and drives the clamping jaw 306 to clamp the material box. Then the electric cylinder 303 will drive the clamping jaw 306 to move upward to the set position, and the height of this position is higher than the height of the transfer mechanism 4.

[0040] Then the lateral cylinder 402 in the transfer mechanism 4 drives the material box lifting structure to the set position, which corresponds to the position of the material box clamped by the lifting mechanism 3. Then the lifting cylinder 406 in the material box lifting structure extends to drive the tray 408 to move upward, and then the second telescopic cylinder 308 drives the clamping claw 306 to open, and the material box is placed in the tray 408. The third telescopic cylinder 407 retracts to drive the tray positioning block 411 to position and clamp the material box. At this time, the material in the material box can be clamped. The electric cylinder 303 drives the clamping claw 306 to move downward, re-clamp the material box, and wait for the next material discharge cycle.

[0041] After the materials in the material box are completely grabbed, the material box in the tray 408 is moved to the stacking position by the transverse cylinder 402. The stacking cylinder 504 and the lifting cylinder 508 extend, and the clamping structure moves downward along the guide rod 503 to the set position, and then the clamping electric cylinder 511 retracts, and the stacked empty material box is stacked on the empty material box in the tray 408, completing the stacking action.

[0042] After completing the stacking action, the stacking cylinder 504 and the lifting cylinder 508 of the stacking mechanism 4 retract, and the stacked empty material boxes are lifted to a certain height. After the electric cylinder 303 drives the clamp 306 to lift the new material box to the set position, the transverse cylinder 402 drives the material box lifting structure to enter the material picking area and enter the next material discharge cycle.

[0043] When the stacked empty boxes are detected by the stacking mechanism's photoelectric sensor, the stacking cylinder 504 extends, the lifting cylinder 508 extends, and the clamping cylinder 511 retracts. The stacked empty boxes are placed on the belt conveyor line 404, the clamping cylinder 511 retracts, and the empty boxes are transported to the unloading area by the belt conveyor line 404, waiting to be taken away by the operator, thus completing a material discharge cycle.

[0044] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present invention, and these modifications or replacements should be included in the protection scope of the present invention.
