[0002] Due to their ability to store various types of goods, turnover boxes are increasingly favored by the processing industry. Currently, the use and temporary storage of a large number of turnover boxes still require manual labor, which is inefficient, labor-intensive, and lacks automation. Existing stacker cranes can only stack a single item at a time, resulting in low efficiency. How to achieve multiple stacks at once to improve stacking efficiency and reduce costs is a problem that needs to be solved. Summary of the Invention

[0003] This utility model addresses the aforementioned technical problems by proposing a high-efficiency stacking device and a turnover box stacker, which can stack multiple turnover boxes at once and unload and transport them.

[0018] To better understand the above technical solution, the following detailed description is provided in conjunction with the accompanying drawings and specific implementation methods.

[0019] A high-efficiency stacking device, see Figures 1 to 6 It includes a housing 1, and a conveying channel 11 is provided from the top of the housing 1 downward in the front-rear direction. The conveying channel 11 is a T-shaped long groove. Lifting baffles 2 are respectively provided at the front and rear ends of the conveying channel 11. The lifting baffle 2 includes a lifting rod connected to the housing 1, a connecting piece 21 connected to the lifting end of the lifting rod, and a baffle 22 connected to the connecting piece 21. The lifting rod is obscured in the figure and is therefore not shown in the figure. The lifting rod is a cylinder or a hydraulic cylinder, or it can be other telescopic components. To achieve conveying, two rows of conveyor lines are set up in the conveying channel, located on the left and right sides of the lower end of the conveying channel 11. The two rows of conveyor lines are synchronized. To facilitate cleaning or maintenance, the conveyor line 3 is changed from the original belt conveyor to a roller conveyor line 3, which includes multiple supports 31 set on the left and right sides of the bottom end of the conveying channel 11. The supports 31 are inverted L-shaped. The vertical part of the supports 31 is a columnar structure and is connected to the lower end of the conveying channel 11. The horizontal part of the supports 31 serves as a support shaft. Multiple conveyor rollers 32 are connected to the supports 31. The conveyor rollers 32 can rotate relative to the supports 31. Specifically, the conveyor rollers 32 are rotatably connected to the horizontal part of the supports 31. The side of the conveying channel 11 is provided with a rotating shaft connected to the conveyor rollers 32. The conveyor rollers 32 are driven by the rotating shaft, belt drive or chain drive. A lifting platform 4 is provided between the conveyor lines 3. The lifting platform 4 is located in the middle of the lower end of the conveyor channel 11. The lifting platform 4 is provided with at least two stacking areas. The lifting platform 4 includes a support platform and a lifting rod connected to the bottom of the support platform to drive the support platform to lift. The lifting rod can be a single rod or multiple rods. When there are multiple rods, a synchronous lifting method is adopted. The lifting rod is a cylinder, a hydraulic cylinder, or other lifting components. To achieve stacking and lifting, a claw mechanism 5 is provided in each stacking area. The claw mechanisms 5 move synchronously and are located on the left and right sides of the upper end of the conveying channel 11. The claw mechanism 5 has movable claws 51. The claw mechanism 5 includes a driving component 52 connected to the left and right side walls of the conveying channel 11 to drive the claws 51 to move. The driving component 52 is connected to the claws 51. The driving component 52 includes two support blocks 521 connected to the conveying channel 11. A rotating shaft 522 is connected between the two support blocks 521. Two claws 51 are provided, located outside the support blocks 521 and connected to the rotating shaft 522. The end of the claw 51 is provided with a slot 511. The two claws 51 are connected by a connecting shaft 523. A telescopic rod 524 is provided on the side wall of the conveying channel 11 to drive the claws 51 to move. A T-shaped connecting rod 525 is provided at the end of the telescopic rod 524. The transverse end of the T-shaped connecting rod 525 is movably connected to the connecting shaft 523 by a retaining ring 526. When the lifting platform 4 supports the turnover box to rise, the turnover box pushes the claw 51 to move outward. When the lifting platform 4 descends, the claw 51 moves inward to support the handle of the turnover box. On the side wall of the conveying channel 11, between the stacking areas, there is a retractable correction part 6, including a transverse telescopic rod 61 and a spherical guide head 62 connected to the end of the telescopic rod 61. It also includes multiple sensors 7 for detecting the position of the turnover box. The sensors 7 are photoelectric position sensors. In order to avoid interference caused by the light emitted by the sensors 7 passing through the holes or hollows on the turnover box, the sensors 7 are set at an angle of 30-45°. Side guide rods 8 are connected to the left and right side walls of the conveying channel 11. The distance between the two side guide rods 8 is based on the size of the turnover box that can pass through. The side guide rods 8 are located above the conveying rollers 32 of the roller conveyor line. The side guide rods 8 include multiple adjusting screws 81 set on the left and right sides of the stacking area. The adjusting screws 81 are set horizontally. The end of the adjusting screws 81 facing the stacking area is connected to a guide rod 82 horizontally so that the distance between the two side guide rods 82 can be adjusted. The end of the guide rod 82 facing the input turnover box is turned outward to form an opening between the turned-out parts of the two side guide rods 82. It also includes a touch screen 9 and control buttons 10, which are located on the rear end face of the housing 1; A turnover box stacker employs the aforementioned high-efficiency stacking device. When external turnover boxes are continuously conveyed to the conveyor line, the lifting baffle at the front end of the conveyor channel rises to block the turnover boxes that first enter the conveyor line into the stacking area near the output end. As the turnover boxes are continuously fed onto the conveyor line, the correction unit extends to correct the second turnover box and the first turnover box that entered earlier, and space them in the corresponding stacking area. The turnover boxes are fed in sequence, and the correction unit works in sequence until the last turnover box is located in the last stacking area. At this time, the lifting baffle at the rear end of the conveyor channel rises to block the external turnover boxes from being fed onto the conveyor line, and the conveyor line stops. The lifting platform supports the rise of the turnover boxes in each stacking area. The turnover boxes in each stacking area push the corresponding claws to move outward. After the lifting platform rises to the stacking position, it descends. The claws in the claw mechanism move inward to support the handles of the turnover boxes, which is one stacking mode. This stacking pattern is repeated until the turnover boxes are stacked to a specific position. Then, the lifting platform continues to rise to the unloading position, the claws in the claw mechanism move outward, the claws separate from the turnover box handles, and the lifting platform supports the stacked turnover boxes to descend to the initial position. The conveyor line outputs stacked containers from each stacking area, completing one stacking cycle. After one stacking cycle is completed, the next stacking cycle begins.

[0020] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
