It should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0027] As shown in Figure 1 , Figure 2 , Figure 3 , the present application provides an automatic unlocking and turning device, which comprises a base 4, a stacking mechanism 9, a supporting piece 7, a reset assembly and a guide 8. The base 4 is L-shaped and comprises a horizontal part and a vertical part connected integrally. The stacking mechanism 9 is rotationally connected to the horizontal part. The supporting piece 7 is slidingly connected to the horizontal part. The supporting piece 7 is in contact with the lower surface of the stacking mechanism 9. The lower surface of the stacking mechanism 9 is provided with a curved surface, and the curved surface is provided with a recess 911. The guide 8 is arranged at the bottom of the telescopic frame. The base 4 slides along the vertical direction of the telescopic frame. When the base 4 moves to the lower end of the telescopic frame, the guide 8 drives the supporting piece 7 to slide in the horizontal direction. Under the action of gravity, the stacking mechanism 9 makes the supporting piece 7 move along the curved surface of the lower surface of the stacking mechanism 9 and into the recess, thereby realizing the turning of the stacking mechanism 9. A limiting piece 2 is arranged at the end of the horizontal part away from the vertical part. When the guide 8 is not in contact with the supporting piece 7, the limiting piece 2 is in contact with the supporting piece 7, thereby preventing the supporting piece 7 from being infinitely extended under the action of the reset assembly.

[0028] The reset assembly comprises a spring 6 and a spring mounting rod 5, the spring mounting rod 5 is fixedly connected to the side wall of the vertical part of the base 4, the end of the spring mounting rod 5 away from the vertical part of the base 4 is connected to the spring 6, and the other end of the spring 6 is connected to the side wall of the support 7.

[0029] The guide 8 comprises a bottom plate 81 and a side plate 82, the bottom plate 81 is fixed to the lower end of the telescopic frame, the bottom plate 81 is horizontally arranged, the two sides of the upper surface of the bottom plate 81 are fixedly connected to the side plate 82 respectively, or the bottom plate 81 and the side plate 82 are integrally connected, the side plate 82 is arranged perpendicularly to the bottom plate 81, and an inclined surface is arranged on the side of the side plate 82 close to the telescopic frame, and the inclined surface is arranged to be inclined upward from the end close to the telescopic frame to the end away from the telescopic frame.

[0030] The side wall of the support 7 is fixedly connected to a push rod 71, the upper end of the push rod 71 is provided with a supporting wheel, the supporting wheel is used for supporting a stacking mechanism 9, and the supporting wheel is in contact with the curved surface of the lower surface of the stacking mechanism 9; the lower surface of the stacking mechanism 9 is fixedly connected to a turnover part 91, the turnover part 91 comprises an integral horizontal section and an inclined section, the horizontal section and the inclined section form a recess 911, and the turnover angle, the turnover speed and the turnover restoring force are controlled through the curved recess 911; the base 4 is provided with a through groove 41, the through groove 41 is arranged along the length direction of the base 4, the number and position of the through groove 41 correspond to the number and position of the side plate 82, and the through groove 41 is convenient for the side plate 82 to pass through.

[0031] The base 4 is mounted on the side wall of a sliding block 3, the sliding block 3 is mounted on the telescopic frame 1, the sliding block 3 realizes up-down movement on the telescopic frame 1 through a screw rod and a motor, so that different height goods can be loaded and transported.

[0032] The working principle of the automatic unlocking turnover device provided by the application is as follows:

[0033] (1) Initial stage (the stage when the guide 8 just contacts the base 4), the limiting part 2 blocks the push rod 71 from being infinitely stretched under the action of the spring 6, at this time, the push rod 71 just abuts against the horizontal section of the turnover part 91, so that the stacking mechanism 9 is horizontal.

[0034] (2) When the goods at the bottom of the compartment body are stacked, the side plate 82 passes through the corresponding through groove 41, in the process that the base 4 continues to move downward, the push rod 71 moves downward along the inclined surface of the side plate 82, and the spring 6 is compressed, in the process that the support 7 compresses the spring 6, under the action of gravity, the inclined section of the turnover part 91 is in contact with the support 7, at this time, the stacking mechanism 9 rotates counterclockwise relative to the horizontal part of the base 4, when the push rod 71 moves into the recess of the turnover part 91, the stacking mechanism 9 stops rotating, that is, rotates to the lowest end position, for example, Figure 3 、 Figure 4As shown, the stacking mechanism 9 is in contact with the stacking surface of the bottom of the box away from the end of the telescopic frame 1, so that the goods slide downward along the inclined upper surface of the overturned stacking mechanism 9, and the goods are stably stacked on the stacking surface of the bottom of the box, if the stacking mechanism 9 cannot be overturned, the stacking mechanism 9 always remains horizontal, and the goods are prone to be dumped when stacked on the stacking surface from the end of the stacking mechanism 9; and as shown, in one specific example of the present application, the stacking mechanism 9 is overturned to form a downward inclination during stacking, which can be reduced by about 150mm compared to the case where the stacking mechanism 9 always remains horizontal, and the small-size goods are prevented from being pushed out and dumped, and the goods at the lower position are facilitated to be stacked. Figure 4

[0035] When the base 4 moves upward, the guide 8 is gradually separated from the support 7, the support 7 is reset under the action of the spring 6, and moves along the inclined section to the horizontal section, so that the stacking mechanism 9 rotates clockwise to the horizontal state.
