[0045] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0046] Please refer to Figures 1 to 4 The present invention provides a flexible stacking device for bundled bamboo pieces, comprising a pneumatic lifting mechanism 1 and an adaptive clamping mechanism 2;

[0047] The lifting end of the pneumatic lifting mechanism 1 is connected to the adaptive clamping mechanism 2. The pneumatic lifting mechanism 1 includes a first cylinder 11, a housing 12, a synchronous belt 17, a guide wheel 13, a pressure wheel 16, a core shaft 14, a spring box 15 and a scroll spring;

[0048] The housing 12 is fixed to the piston rod of the first cylinder 11;

[0049] The core shaft 14 is installed in the housing 12, and one end of the core shaft 14 extends outside the housing 12 and is connected to the inner ring of the spiral spring;

[0050] The outer ring of the spiral spring is fixed on the spring box 15;

[0051] The spring box 15 is fixedly arranged on one side of the outer wall of the housing 12;

[0052] The guide wheel 13 is fixed on the core shaft 14;

[0053] The synchronous belt 17 is installed on the guide wheel 13, one end of the synchronous belt 17 is fixed, and the other end of the synchronous belt 17 is connected to the adaptive clamping mechanism 2;

[0054] The pressure wheel 16 is rotatably mounted in the housing 12 and is located above the guide wheel 13, restricting the synchronous belt 17 on the guide wheel 13;

[0055] When in use, the piston of the first cylinder 11 is lowered to the lowest point. Since the adaptive clamping mechanism 2 is connected to the adaptive clamping mechanism 2 by means of a synchronous belt 17, when the adaptive clamping mechanism 2 falls on the bundled bamboo pieces, the bamboo pieces will only be affected by the gravity of the adaptive clamping mechanism 2 itself, achieving flexible contact and avoiding damage to the bamboo pieces. When the adaptive clamping mechanism 2 clamps the bundled bamboo pieces, the piston of the first cylinder 11 extends to the highest point, and the adaptive clamping mechanism 2 lifts the bamboo pieces; when the adaptive clamping mechanism 2 starts to fall and touches the bottom with the top of the stacked bamboo pieces, both sides of the synchronous belt 17 are in a taut state; when the adaptive clamping mechanism 2 touches the top of the stacked bamboo pieces, the first cylinder 11 is pressed The piston 11 will continue to descend to the bottom. During this process, both sides of the synchronous belt 17 will be in a relaxed state. At this time, there is a risk of the piston rod spinning. In this application, the preload force of the spiral spring is transmitted to the guide wheel 13 through the core shaft 14. When the side of the synchronous belt 17 connected to the adaptive clamping mechanism 2 is relaxed, it will drive the guide wheel 13 to rotate in the opposite direction, and the synchronous belt 17 connected to one side of the adaptive clamping mechanism 2 will be retracted to the other side. The reaction force of the tightened synchronous belt 17 connected to one side of the adaptive clamping mechanism 2 can prevent the piston rod from spinning. Therefore, the synchronous belt 17 connected to one side of the adaptive clamping mechanism 2 can always remain in a tensioned state, avoiding the problem of the synchronous belt 17 being entangled.

[0056] refer to Figure 3 In this embodiment, the adaptive clamping mechanism 2 includes an L-shaped vertical plate 21, a transverse guide rail 26, a longitudinal guide rail 24, a fixed claw 29, a movable claw 27, a second cylinder 22, a transverse slider 28, a longitudinal slider 23 and a connecting rod 25;

[0057] The L-shaped vertical plate 21 is connected to the lifting end of the synchronous belt 17;

[0058] The longitudinal guide rail 24 is installed on the vertical surface of the L-shaped vertical plate 21;

[0059] The longitudinal slider 23 is slidably mounted on the longitudinal guide rail 24;

[0060] The transverse guide rail 26 is installed on the horizontal surface of the L-shaped vertical plate 21;

[0061] The transverse slider 28 is slidably mounted on the transverse guide rail 26;

[0062] The second cylinder 22 is mounted on the L-shaped vertical plate 21 and is connected to the longitudinal slider 23 via a piston rod;

[0063] One end of the connecting rod 25 is rotatably connected to the longitudinal slider 23, and one end of the connecting rod 25 is rotatably connected to the transverse slider 28;

[0064] The movable claw 27 is fixed on the surface of the transverse slider 28;

[0065] The fixed claw 29 is provided on the surface of the bend of the L-shaped vertical plate 21 and is arranged opposite to the movable claw 27;

[0066] When in use, the second cylinder 22 drives the longitudinal slider 23 to move downward. Under the action of the connecting rod 25, the transverse slider 28 moves along the transverse guide rail 26, causing the moving claw 27 to move toward the fixed claw 29, thereby realizing the retrieval of bamboo bundles of different widths.

[0067] In this embodiment, a moving mechanism 3 is also included, which includes a track 31 and a base 32 that can move on the track 31. The pneumatic lifting mechanism 1 is installed on the base 32, and the end of the synchronous belt 17 away from the adaptive clamping mechanism 2 is fixed on the base 32; the movement control of the pneumatic lifting mechanism 1 is achieved by moving the base 32.

[0068] In this embodiment, two groups of pneumatic lifting mechanisms 1 are provided and installed at both ends of the upper surface of the base 32. The two groups of pneumatic lifting mechanisms 1 cooperate with the adaptive clamping mechanism 2 to achieve the grasping of the ends of the bundled bamboo pieces.

[0069] The working principle of the present invention is as follows:

[0070] The moving mechanism 3 moves the pneumatic lifting mechanism 1 above the conveyor line, the moving claw 27 of the adaptive clamping mechanism 2 is retracted and opened, the piston of the first cylinder 11 of the pneumatic lifting mechanism 1 drops to the lowest point, the adaptive clamping mechanism 2 falls on the bundled bamboo pieces, the moving claw 27 is retracted to clamp the bamboo pieces, and then the piston of the first cylinder 11 of the pneumatic lifting mechanism 1 is extended to the highest point, the adaptive clamping mechanism 2 lifts the bamboo pieces, and cooperates with the moving mechanism 3 to move the pneumatic lifting mechanism 1 above the material pile, the piston of the first cylinder 11 drops to the lowest point, and the bundled bamboo pieces fall on the top of the material pile, and then the moving claw 27 is retracted and opened, and the bundled bamboo pieces are separated from the adaptive clamping mechanism 2, completing a flexible stacking. Then the piston of the first cylinder 11 is extended to the highest point, waiting for the next cycle.
