The short column 7 further drives the left slide 9 to move up and down along the slide rail 8 through the slide slot 11, and then drives the connecting plate 10 and the right slide 9 to move up and down. The two slides 9 further drive multiple rollers 12 to move up and down. When the roller 12 rises, the pallet placed on the roller 12 is lifted. When the pallet is lifted to the ear 18, the pallet continues to move upward and drives the ear 18 to rotate upward, so that the pallet moves to the top of the ear 18. At this time, the ear 18 rotates downward and resets under the action of its own gravity. When the roller 12 descends, the pallet is placed on the ear 18. This operation is repeated to stack multiple pallets in sequence. The utility model can automatically stack pallets with a high degree of automation, reduces the work intensity of operators, and saves labor costs.

[0023] As a technical optimization scheme of the utility model, the right ends of multiple rollers 12 extend to the right side of the right skateboard 9 and are fixedly connected to a double-groove pulley 13. The multiple double-groove pulleys 13 are connected by belt transmission. A mounting plate 14 is fixedly connected to the right end surface of the right skateboard 9. A servo motor 15 is fixedly connected to the upper end surface of the mounting plate 14. The output end of the servo motor 15 is fixedly connected to one of the double-groove pulleys 13.

[0024] In this embodiment: the servo motor 15 is started, and the servo motor 15 drives the double-groove pulley 13 connected to its output end to rotate, and then drives multiple double-groove pulleys 13 to rotate synchronously through the belt, and the multiple double-groove pulleys 13 further drive the roller shaft 12 to rotate synchronously, and then the pallet on the roller shaft 12 is transported, so that the pallet can enter and exit the placement rack 2.

[0025] As a technical optimization solution of the present invention, the bracket 18 is L-shaped.

[0026] In this embodiment, by setting the support ear 18 to be L-shaped, the support ear 18 can be driven to rotate upward when the tray moves upward to support the tray.

[0027] As a technical optimization solution of the present invention, a feed roller 19 is installed on the upper end surface of the second support plate 16 located at the front lower side.

[0028] In this embodiment, a feed roller 19 is installed on the upper end surface of the second support plate 16 at the lower front side, so that the tray can be easily put into the placement rack 2.

[0029] As a technical optimization solution of the present invention, a discharge roller 20 is installed on the upper end surface of the second support plate 16 located on the upper rear side.

[0030] In this embodiment, a discharging roller 20 is installed on the upper end surface of the second supporting plate 16 at the rear upper side, so that the tray can be easily discharged from the placement rack 2.

[0033] The working principle and use process of the utility model are as follows: when in use, first place one end of the pallet on the front roller shaft 12, and then start the servo motor 15. The servo motor 15 drives the double-groove pulley 13 connected to its output end to rotate, and then drives multiple double-groove pulleys 13 to rotate synchronously through the belt, and multiple double-groove pulleys 13 further drive the roller shaft 12 to rotate synchronously, and then the pallet on the roller shaft 12 is transported. When the pallet is transported to the center of multiple roller shafts 12, stop the servo motor 15, and then start the drive motor 5. The drive motor 5 drives the connecting rod 6 to rotate, and then drives the short column 7 to rotate. The short column 7 further drives the left slide 9 to move upward along the slide rail 8 through the slide groove 11, and then drives the connecting plate 10 and the right slide 9 upward. The two slide plates 9 further drive the multiple rollers 12 to move upward, thereby lifting the pallet placed on the rollers 12. When the pallet is lifted to the ear 18, the pallet continues to move upward, driving the ear 18 to rotate upward, so that the pallet moves to above the ear 18. At this time, the ear 18 rotates downward and resets under the action of its own gravity. When the roller 12 descends, the pallet is placed on the ear 18. This operation is repeated to stack multiple pallets in sequence. When a certain number of pallets are stacked, the servo motor 15 is started, and the servo motor 15 drives the multiple rollers 12 to rotate to directly transport the entire pallet. The utility model can automatically stack pallets with a high degree of automation, reduces the work intensity of operators, and saves labor costs.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
