Description

Technical Field

[0001] The invention relates to the field of bamboo strip palletizing, in particular to a flexible synchronous palletizing device. Background Art

[0002] During the bamboo strip palletizing process, there are at least the following problems: 1. Since the bamboo strips themselves are bent, twisted and warped, the bending direction of the head and tail is uncertain, and the thickness of different batches of bamboo strips is also different. Therefore, the height and thickness of the bundle of bamboo strips brought by the bundled bamboo strip discharging device are different. The holding mechanism needs to adapt to the clamping positions with different heights at the head and tail; 2: There are many types of bamboo strips to be sorted, so the heights of different piles are different, and the widths of bundled bamboo strips are also different. Therefore, piles of different heights will form a narrow space, and the clamping mechanism needs to enter the narrow space to stack bundles of bamboo strips of different widths; 3: The bundled bamboo strips are stacked and tied with multiple layers of bamboo strips, which are easy to break apart under impact. Since the bamboo strips themselves are bent, twisted and warped, the bending direction of the head and tail is uncertain, and the thickness of bamboo strips in different batches is also different. Therefore, the height difference between the head and tail is greater after multiple layers of materials are stacked. If the bamboo strips are released based on one end as the height, the other end of the bamboo strips will drop like a free fall, causing the bundled bamboo strips to be broken up.

[0013] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0014] Please refer to Figures 1 to 4 , the present invention provides a flexible synchronous stacking device, including a bottom plate 1, a flexible lifting mechanism 2 and a clamping mechanism 3; The flexible lifting mechanism 2 is installed on the bottom plate 1, and the flexible lifting mechanism 2 includes a motor 21, a reducer 22, a synchronous shaft 23, a bearing seat, a capstan 24, a chain 26, a connecting plate 25, a fixing plate 29 and a proximity sensor 28; Two bearing seats are fixedly mounted on the bottom plate 1 and are arranged symmetrically on the left and right sides; The synchronous shaft 23 is installed between the two bearing seats, and the two ends of the synchronous shaft 23 are fixedly connected with a capstan 24; The motor 21 is connected to the synchronous shaft 23 via the reducer 22; The chain 26 is wound around the winch 24; A fixing plate 29 is installed on the surface of the connecting plate 25. A monitoring hole is opened on the fixing plate 29. A monitoring rod 27 is installed in the monitoring hole. Limiting blocks are installed at both ends of the monitoring rod 27, and one end of the top of the monitoring rod 27 is connected to the free end of the chain 26. The proximity sensor 28 is mounted on the surface of the connecting plate 25, and the monitoring rod 27 contacts the proximity sensor 28 when it descends to the lowest position; The clamping mechanism 3 is mounted on the connecting plate 25; When in use, the clamping mechanism 3 descends as the winch 24 lowers the chain 26. When the bottom of one of the clamping mechanisms 3 touches the material, the clamping mechanism 3 stops moving downward, and the chain 26 and the monitoring rod 27 continue to descend until the monitoring rod 27 approaches the proximity sensor 28, thereby determining the height of the material at that end. Similarly, as the winch 24 lowers the chain 26, the bottom of the clamping mechanism 3 at the other end also touches the material, and the corresponding proximity sensor 28 receives the proximity signal of the monitoring rod 27, which means that both ends of the bundled bamboo strips have touched the top of the material pile. At this time, the descent stops and the clamping mechanism is released. 3. The bundled bamboo strips are placed stably on the top of the material pile to prevent the impact from breaking up the bundled bamboo strips and realize flexible material unloading. During the material removal process, the bamboo strips themselves are bent, twisted and warped, so that the heights of the two ends of the bundled bamboo strips are different. Therefore, after the two sets of clamping mechanisms 3 are respectively in contact with the two ends of the bundled bamboo strips, the heights of the two sets of clamping mechanisms 3 are different. As the chain 26 is continuously wound, the clamping mechanism 3 with a lower height will rise first until it is flush with the other set of clamping mechanisms 3, and then rise synchronously, so that the clamped bundled bamboo strips can be moved and stacked in a horizontal posture, which is beneficial to improving the stacking efficiency of the bundled bamboo strips.

[0015] In this embodiment, a guide rod 210 is vertically arranged on the top of the connecting plate 25, and a guide tube 211 corresponding to the guide rod 210 is opened on the bottom plate 1; When in use, the guide rod 210 and the guide tube 211 are arranged to ensure that the connecting plate 25 can maintain a vertical direction for lifting and lowering.

[0016] In this embodiment, the clamping mechanism 3 includes a fixed clamping jaw 33, a movable clamping jaw 34, a transverse slide rail 31, a transverse slider, a vertical slide rail 35, a vertical slider 36, a connecting rod 37 and a cylinder 38; The transverse slide rail 31 is installed on the surface of the connecting plate 25; The transverse slide block is slidably mounted on the transverse slide rail 31; The fixed clamping claw 33 is arranged on one side of the transverse slide rail 31; The movable clamping jaw 34 is fixed on the surface of the horizontal slider, and cooperates with the fixed clamping jaw 33 to clamp the bamboo strip; The vertical slide rail 35 is arranged on the surface of the connecting plate 25 and is arranged above the horizontal slide rail 31; The vertical slide block 36 is slidably mounted on the vertical slide rail 35; The cylinder 38 is fixed on the connecting plate 25, and the piston rod of the cylinder 38 is connected to the vertical slider 36; One end of the connecting rod 37 is rotatably connected to the vertical slider 36, and the other end of the connecting rod 37 rotates the horizontal slider; When in use, the cylinder 38 drives the vertical slider 36 to move downward, and under the action of the connecting rod 37, the horizontal slider on the horizontal slide rail 31 is driven to move, thereby controlling the distance between the fixed clamping jaw 33 and the movable clamping jaw 34 to achieve clamping control of the bamboo strips.

[0017] In this embodiment, a gantry 4 is also included. The base plate 1 is installed on the top of the gantry 4 through a transverse moving assembly 5. The transverse moving assembly 5 includes a transverse moving track, a transverse moving slider 32, a guide rack, a driving gear and a motor 21. The transverse moving track and the guide rack are both installed on the top of the gantry 4. The transverse moving slider 32 is slidably installed on the transverse moving track. The base plate 1 is fixed on the transverse moving slider 32. The driving gear is meshed and connected to the guide rack, and the driving gear is connected to the motor 21. The motor 21 is installed on the base plate 1; When in use, the motor 21 drives the driving gear to rotate, and with the cooperation of the guide rack, it can drive the bottom plate 1 to move along the transverse track, thereby realizing the adjustment and control of the position of the bottom plate 1.

[0018] In this embodiment, a stacking rack 6 is further included. The stacking rack 6 is installed below the gantry 4 and a plurality of material storage bins are arranged on the stacking rack 6 .

[0019] The working principle of the present invention is as follows: When the winch 24 lowers the chain 26, the clamping mechanism 3 descends. When the bottom of one of the clamping mechanisms 3 touches the material, the clamping mechanism 3 stops moving downward, and the chain 26 and the monitoring rod 27 continue to descend until the monitoring rod 27 approaches the proximity sensor 28, thereby determining the height of the material at that end. Similarly, as the winch 24 lowers the chain 26, the bottom of the clamping mechanism 3 at the other end also touches the material, and the corresponding proximity sensor 28 receives the proximity signal of the monitoring rod 27, which means that both ends of the bundled bamboo strips have touched the top of the material pile. At this time, the descent stops and the clamping mechanism 3 is released. The bundled bamboo strips are placed stably on the top of the material pile to prevent the impact from breaking up the bundled bamboo strips, and flexible material unloading is achieved. During the material removal process, the bamboo strips themselves are bent, twisted and warped, so that the heights of the two ends of the bundled bamboo strips are different. Therefore, after the two sets of clamping mechanisms 3 are respectively in contact with the two ends of the bundled bamboo strips, the heights of the two sets of clamping mechanisms 3 are different. As the chain 26 is continuously wound, the clamping mechanism 3 with a lower height will rise first until it is flush with the other set of clamping mechanisms 3, and then rise synchronously, so that the clamped bundled bamboo strips can be moved and stacked in a horizontal posture, which is beneficial to improving the stacking efficiency of the bundled bamboo strips.
