Detailed Implementation
[0022] Example: An automatic steel pipe palletizing anti-rolling positioning conveyor, such as... Figures 1-5 As shown, the system includes a bracket 1, a first support frame 11, guide rollers 12, a conveyor belt 13, a first motor 131, a conveyor block 14, a storage platform 15, a second support frame 16, guide rollers 17, a controller 18, a palletizing assembly, and a positioning assembly. The first support frame 11 is bolted to the right side of the bracket 1, and multiple vertically arranged guide rollers 12 are rotatably connected between them to guide the steel pipes to move smoothly. Multiple sets of conveyor belts 13 with a left-high and right-low tilt are installed on the left and right sides of the bracket 1. The left and right sides of the conveyor belts 13 are connected to each other. The steel pipes are guided into the tilted conveyor belts 13 via the guide rollers 12. A first motor 131 with its output shaft facing the rear is installed on the front right side of the bracket 1, and its output shaft end is fixed to the right side of the conveyor belt 13. The connection includes multiple transmission blocks 14 fixed equidistantly along the circumferential direction on the outer surface of the conveyor belt 13. These transmission blocks 14 are tilted to the left and are in a figure-eight shape to push the steel pipe forward and prevent it from rolling. A right-extending platform 15 is bolted between the left side of the support 1 and the conveyor belt 13. The right extension of the platform 15 is tilted with the left side lower than the right side to facilitate the sliding of the steel pipe. A second support frame 16 is bolted to the left side of the support 1. Multiple guide rollers 17 are rotatably connected between the two to assist the steel pipe in smoothly entering the subsequent work station. A controller 18 is installed on the upper right side of the first support frame 11. The first motor 131 is electrically connected to the controller 18. A palletizing assembly is provided at the rear of the support 1, and a positioning assembly is provided at the front of the support 1.
[0023] Operators can apply the corresponding technical solutions in this device to the technology of steel pipe conveying and stacking according to specific circumstances. When it is necessary to use this device to assist in the automatic stacking and anti-rolling positioning of steel pipes, the steel pipes to be stacked are guided by the guide rollers 12 onto the inclined conveyor belts 13 on the left and right sides of the support 1. First, the operator adjusts the parameters through the controller 18, and then starts the first motor 131. The first motor 131 drives the conveyor belt 13 to rotate. The conveyor blocks 14 distributed at equal intervals on its outer surface push the steel pipes forward in sequence. The "7"-shaped design of the conveyor blocks 14 can more effectively prevent the steel pipes from slipping and use its tilt angle to prevent the steel pipes from rolling during the transmission process.
[0024] like Figure 1 , Figure 2 and Figure 5 As shown, the palletizing assembly includes a third support frame 3, a second guide rod 31, a rodless cylinder 32, a slide 33, a first cylinder 34, a second mounting plate 35, and an electromagnet 36. The third support frame 3 is installed on the rear side of the bracket 1. Two second guide rods 31 are bolted to the left and right sides of the top of the third support frame 3. A rodless cylinder 32 is installed at the middle of the top of the third support frame 3. A slide 33 is slidably connected to the rodless cylinder 32. The slide 33 is slidably engaged with the second guide rods 31. A first cylinder 34 with its output shaft facing downward is installed on the top of the slide 33. Its output end is bolted to the second mounting plate 35. Multiple sets of electromagnets 36 are installed at the bottom of the second mounting plate 35 for adsorbing steel pipes for palletizing operations. The rodless cylinder 32, the first cylinder 34, and the electromagnets 36 are all electrically connected to the controller 18.
[0025] When the steel pipes are conveyed to the left side of the support 1, they slide sequentially onto the inclined surface on the right side of the platform 15, which is lower on the left and higher on the right, and are arranged horizontally on the left side of the platform 15. Then, the rodless cylinder 32 drives the slide 33 to move laterally along the second guide rod 31 to the corresponding target position on the upper part of the platform 15. The first cylinder 34 below the slide 33 drives the second mounting plate 35 to move down, and the steel pipes are attracted by multiple sets of electromagnets 36 at the bottom. After the attraction is completed, the cylinder is reset and the whole is moved to the top of the stacking point by the rodless cylinder 32. The electromagnets 36 are de-energized and the steel pipes are released, completing one stacking action. The controller 18 stacks the steel pipes sequentially according to the preset parameters. When a certain height is reached, the stacking is completed. After one set is stacked, the controller 18 starts the second motor 5 according to the preset parameters. The second motor 5 drives the front guide roller 17 to rotate. The guide rollers 17 rotate in coordination with each other through the belt 51, which further assists in the smooth conveying of the steel pipes and improves the conveying efficiency, thus completing one workflow.
[0026] like Figure 1 , Figure 2 and Figure 5As shown, the positioning assembly includes an electric guide rail 2, a first mounting plate 21, a dual-axis motor 22, a positioning plate 23, and a first guide rod 24. The electric guide rail 2 is symmetrically installed on the front and rear sides of the top of the bracket 1. The first mounting plate 21 is slidably connected to the side of the electric guide rail 2 that is close to each other. The dual-axis motor 22 is installed at the bottom of the first mounting plate 21. The positioning plate 23 is connected to the output shaft on both sides of the motor 22 by a lead screw thread. The first guide rod 24 is provided between the tops of the two positioning plates 23 to ensure the stable movement of the positioning plate 23. The electric guide rail 2 and the dual-axis motor 22 are both electrically connected to the controller 18.
[0027] like Figures 1-5 As shown, it also includes a third mounting plate 4, a limiting rod 41, a baffle 42, a pad 43, a spring 44, a second motor 5, and a belt 51. The third mounting plate 4 is installed on the rear right side of the first support frame 11. The top of the third mounting plate 4 has a first sliding groove, in which the limiting rod 41 is slidably connected. The upper left and right sides of the limiting rod 41 have second sliding grooves and the baffle 42 is slidably connected to them, which is used to adjust the initial position of steel pipes of different specifications. The front side of the baffle 42 is slidably connected to the pad 43, and the spring 44 is connected between the pad 43 and the baffle 42 to buffer the impact force of the steel pipe. The rear front side of the second support frame 16 is equipped with a second motor 5, whose output axis is connected to the frontmost guide roller 17 to the right, and the adjacent guide rollers 17 are connected to belts 51. The second motor 5 is electrically connected to the controller 18.
[0028] When stacking different sizes of steel pipes, the operator can first adjust the initial position of the steel pipes of different specifications, slide the upper limit rod 41 of the third mounting plate 4 to a suitable position to match the length of the steel pipe, and then fix it with bolts. The operator can also adjust the appropriate height of the baffle 42 on the limit rod 41 to match the height of different steel pipes. The front end of the baffle 42 is equipped with a pad 43 and a spring 44 to buffer the impact and prevent the steel pipes from being damaged by collision. To prevent rolling, the operator can drive the dual-axis motor 22 through the controller 18 to make the positioning plates 23 on both sides of the output shaft move closer or further away synchronously through the lead screw, thereby limiting the steel pipes of different specifications and preventing them from shifting or rolling during the stacking process, ensuring positioning accuracy. If the steel pipe is short, the first mounting plate 21 can be raised by the electric guide rail 2, moving past the transmission block 14 to a position that matches the steel pipe specification. Then, the above operation can be repeated. During the entire operation, all actuators are electrically connected to the controller 18 to realize the automated and coordinated operation of the whole machine, thereby completing the integrated operation of steel pipe from conveying, positioning to stacking.
