The difference between the full tray stack and the empty tray stack is only whether there is the material 5. In this embodiment, the automatic loading bin pushes the full tray stack into the bin body 1 of the full tray bin through the trolley 3, and lifts the full tray stack through the lifting device 2 of the full tray bin to lift the tray 6 filled with the material 5 at the top of the full tray stack to the feeding station. After all the material 5 in the tray 6 at the feeding station is taken away, the empty tray 6 at the feeding station is stacked onto the lifting device 2 of the empty tray bin through the tray handling device 4 to form an empty tray stack, and then the empty tray stack is lowered onto the trolley 3 of the empty tray bin through the lifting device 2 of the empty tray bin, thus realizing the automatic loading of the material 5, ensuring the continuity of the production process, meeting the production beat requirements, and greatly improving the production efficiency.

[0026] The lifting device 2 in this embodiment includes a vertical reciprocating linear motion driving mechanism arranged on the bin body 1 and a lifting seat 21 arranged on the vertical reciprocating linear motion driving mechanism and slidably arranged on the bin body 1.

The lifting motor 22 is arranged on the bin body 1, the lifting lead screw 23 is rotatably arranged on the bin body 1 and connected to the lifting motor 22. A lifting slide rail 13 is arranged on the bin body 1, and the lifting seat 21 is arranged on the slider of the lifting slide rail 13 and connected to the lifting nut seat 24. The lifting motor 22 drives the lifting lead screw 23 to rotate so that the lifting nut seat 24 rises or falls along the lifting lead screw 23, thereby driving the lifting seat 21 connected to the lifting nut seat 24 to rise or fall along the lifting slide rail 13. In practical applications, the vertical reciprocating linear motion driving mechanism can also adopt a telescopic cylinder or an electric push rod, which is specifically selected according to actual needs, and this embodiment does not limit this.

During palletizing, the positioning pin 62 of the upper tray 6 is inserted into the positioning hole 63 of the lower tray 6. In this way, both the positioning between adjacent trays 6 is realized and the stability of the full pallet stack or the empty pallet stack is improved.

[0030] In order to realize the positioning of the full pallet stack or the empty pallet stack, a tray support and positioning structure adapted to the tray 6 is arranged on the supporting seat 31 in this embodiment.

[0033] Specifically, vertically extending palletizing guiding grooves 64 are respectively provided on the opposite sides of the pallet 6. The pallet palletizing guiding structure is a vertically extending palletizing guiding rib 36 adapted to the palletizing guiding groove 64. Of course, the palletizing guiding groove 64 can also be provided on the limiting plate 34, and the palletizing guiding rib 36 can be provided on the pallet 6, which is specifically set according to actual needs, and this embodiment does not limit this.

Of course, a positioning structure common in the prior art can also be adopted, and this embodiment does not limit this.

[0038] In order to reduce the impact force generated by the trolley 3 on the bin body 1 when the trolley 3 is pushed into the bin body 1, a trolley buffering structure is provided between the bin body 1 and the trolley 3 in this embodiment.

[0039] Specifically, the trolley buffering structure includes a hydraulic buffer 16 provided on the bin body 1 and a buffer plate 38 provided on the supporting seat 31.

[0040] In this embodiment, the two bin bodies 1 are integrally provided. The pallet handling device 4 includes a horizontal reciprocating linear motion driving mechanism provided on the two bin bodies 1, a handling frame 41 provided on the horizontal reciprocating linear motion driving mechanism and slidably arranged on the two bin bodies 1, and a clamping mechanism provided on the handling frame 41. The horizontal reciprocating linear motion driving mechanism is used to drive the clamping mechanism to perform horizontal reciprocating linear motion, and the clamping mechanism is used to clamp the pallet 6. With such a setting, the automatic handling of the empty pallet 6 is realized, and the production efficiency is greatly improved.

[0041] In this embodiment, the horizontal reciprocating linear motion driving mechanism is also preferably a lead screw-nut transmission mechanism, which specifically includes a handling motor 42, a handling lead screw 43, and a handling nut seat (not shown in the figure) threadedly connected to the handling lead screw 43. The handling motor 42 is arranged on the bin body 1. The handling lead screw 43 is rotatably arranged on two bin bodies 1 and connected to the handling motor 42. Handling slide rails 44 are arranged on the two bin bodies 1. The handling frame 41 is arranged on the slider of the handling slide rail 44 and connected to the handling nut seat. The handling motor 42 drives the handling lead screw 43 to rotate so that the handling nut seat moves horizontally and reciprocally along the handling lead screw 43, thereby driving the handling frame 41 connected to the handling nut seat to move horizontally and reciprocally along the handling slide rail 44. In practical applications, the horizontal reciprocating linear motion driving mechanism can also adopt a telescopic air cylinder or an electric push rod, which is specifically selected according to actual needs, and this embodiment does not limit this.

[0042] In this embodiment, an avoidance through hole for avoiding the tray 6 is arranged on the handling frame 41.

Each clamping assembly includes a vertical movement driving part 45 arranged below the handling frame 41, a horizontal movement driving part 46 arranged on the vertical movement driving part 45, and a clamping part 47 arranged on the horizontal movement driving part 46. The vertical movement driving part 45 is used to drive the clamping part 47 to move vertically and reciprocally in a straight line, and the horizontal movement driving part 46 is used to drive the clamping part 47 to move horizontally and reciprocally in a straight line. The two clamping parts 47 perform an approaching or separating action under the drive of the two horizontal movement driving parts 46, so as to clamp or release the tray 6.

[0044] Since the air cylinder acts quickly and has a fast response, in this embodiment, both the vertical movement driving part 45 and the horizontal movement driving part 46 are preferably telescopic air cylinders. Of course, an electric cylinder or an electric push rod can also be used, which is specifically selected according to actual needs, and this embodiment does not limit this.

[0045] During use, the full tray stack is pushed into the bin body 1 of the full tray bin by the trolley 3. The lifting device 2 in the full tray bin lifts the full tray stack on the trolley 3 to lift the tray 6 filled with the material 5 at the top of the full tray stack to the loading station. After all the material 5 in the tray 6 at the loading station is taken away, the tray handling device 4 stacks the empty tray 6 at the loading station on the lifting device 2 of the empty tray bin to form an empty tray stack, and then the lifting device 2 of the empty tray bin lowers the empty tray stack onto the trolley 3 of the empty tray bin.

[0046] During this process, after the tray handling device 4 removes the empty tray 6 at the loading station from the loading station, the lifting device 2 in the full tray bin will continue to lift the full tray stack to lift the tray 6 filled with the material 5 at the top of the full tray stack to the loading station; after the tray handling device 4 stacks the empty tray 6 at the loading station onto the lifting device 2 of the empty tray bin, the lifting device 2 in the empty tray bin will descend by the height of one tray 6 to facilitate the tray handling device 4 to continue stacking the trays 6.
