[0018] The present invention describes an automatic flipping and stacking mechanism for channel steel, such as... Figure 1-4 As shown, it includes a conveyor frame 1, which serves as the support frame for the entire mechanism. Several rotatable conveyor rollers 2 are installed on the upper part of the conveyor frame 1. The conveyor rollers 2 can rotate by existing external power sources, such as motors, chains, or belt drives, thereby completing the continuous conveying of channel steel on the conveyor frame 1. The spacing and surface material of the conveyor rollers 2 can be designed according to the size and weight of the channel steel to ensure the stability and reliability of the conveying.

[0019] A flipping storage rack 3 is installed on one side of the conveyor frame 1 along its length to store the channel steel after it has been flipped. The conveyor frame 1 is equipped with a flipping mechanism that flips the channel steel on the conveyor roller 2 and transfers it to the flipping storage rack 3. A discharge trolley 4 is also provided on the side of the conveyor frame 1 near the flipping storage rack 3. The discharge trolley 4 is used to store the channel steel and transfer it to the next process. A suction cup stacking mechanism is installed on the other side of the conveyor frame 1. The suction cup stacking mechanism can transfer the channel steel on the flipping storage rack 3 to the discharge trolley 4 for stacking.

[0020] like Figure 5 As shown, the flipping mechanism includes a rotatable flipping shaft 5 mounted on the conveyor frame 1. The flipping shaft 5 is arranged perpendicular to the conveyor rollers 2, and a bearing seat 6 that cooperates with the flipping shaft 5 is mounted on the conveyor frame 1. Clamping cylinders 7 that can rotate synchronously are mounted at both ends of the flipping shaft 5 extending from the bearing seat 6. The clamping cylinders 7 are located on the conveyor frame 1 between the conveyor rollers 2, and the flipping action of the clamping cylinders 7 will not interfere with the normal rotation of the conveyor rollers 2.

[0021] To achieve clamping and synchronous flipping of the channel steel, a fixed clamping plate 8 is installed on the cylinder body of the clamping cylinder 7, and a movable clamping plate 9 is installed on the piston rod of the clamping cylinder 7. The movable clamping plate 9 and the fixed clamping plate 8 can clamp and fix the channel steel.

[0022] During the feeding of the channel steel on the conveyor roller 2, when the channel steel is located above the clamping cylinder 7, the piston rod of the clamping cylinder 7 moves, causing the moving clamping plate 9 to move closer to the fixed clamping plate 8, thereby fixing and clamping the channel steel. Then, the flipping shaft 5 drives the clamping cylinder 7 and the channel steel on it to flip together, placing the flipped channel steel on the flipping temporary storage rack 3. After that, the moving clamping plate 9 moves away from the fixed clamping plate 8, releasing the clamping of the channel steel, and under the drive of the flipping shaft 5, it rotates in the opposite direction and resets to the conveyor rack 1.

[0023] The suction cup stacking mechanism includes an electromagnetic chuck 10 capable of attracting and gripping channel steel. The electromagnetic chuck 10 can reciprocate laterally and vertically between the conveyor frame 1, the flipping temporary storage frame 3, and the discharge trolley 4. Through the movement of the electromagnetic chuck 10, unflipped channel steel on the conveyor frame 1 and flipped channel steel on the flipping temporary storage frame 3 can be picked up and transferred to the discharge trolley 4 to complete the stacking of channel steel with one flip and one snap-fit. The movement of the electromagnetic chuck 10 can be achieved by existing gantry cranes, hydraulic or pneumatic lifting devices, or other moving mechanisms.

[0024] The automatic flipping and palletizing mechanism for channel steel in this invention integrates functions such as conveying, flipping, temporary storage, gripping, and palletizing, realizing an automated process from conveying to palletizing of channel steel. Its working principle is as follows: after the channel steel is conveyed to the designated position by the conveying roller 2, it is clamped and flipped by the flipping mechanism to the flipping temporary storage rack 3. Then, the suction cup palletizing mechanism transfers the channel steel from the temporary storage rack 3 to the discharge trolley 4 for palletizing.

[0025] Furthermore, in order to drive the rotation of the flipping shaft 5, a flipping motor 11 can be installed on the conveyor frame 1. A first sprocket 12 is installed on the output shaft of the flipping motor 11, and a second sprocket 13 is installed on the flipping shaft 5. A first chain 14 is installed between the first sprocket 12 and the second sprocket 13. When the flipping motor 11 is started, it can drive the clamping cylinder 7 to flip and move onto the flipping temporary storage rack 3 through the transmission of the sprocket and chain. When the flipping motor 11 rotates in the opposite direction, it can drive the clamping cylinder 7 to move and reset, so as to clamp and flip the next channel steel.

[0026] Furthermore, to facilitate the movement of the electromagnetic chuck 10 and complete the picking and transfer of channel steel between the conveyor frame 1 and the discharge trolley 4, and between the tilting temporary storage frame 3 and the discharge trolley 4, such as... Figure 6-8 As shown, the suction cup stacking mechanism may include a column 15, which is located on one side of the conveyor frame 1. A crossbeam 16 is provided on one side of the upper part of the column 15, and the crossbeam 16 is located on the upper side of the conveyor frame 1 and the discharge trolley 4. A transverse shift seat 17 that can move along the length direction is installed on the crossbeam 16. A vertical beam 46 that can be raised and lowered vertically is installed on the transverse shift seat 17. Several electromagnetic chucks 10 are installed at the bottom of the vertical beam 46. Through the drive of the transverse shift seat 17 and the vertical beam 46, the electromagnetic chucks 10 can move laterally and be raised and lowered vertically, thereby completing the movement between the conveyor frame 1 and the discharge trolley 4, and between the flipping temporary storage rack 3 and the discharge trolley 4.

[0027] The horizontal moving seat 17 is equipped with a horizontal moving motor 18 and a vertical moving motor 19. A horizontal moving gear 20 is provided on the output shaft of the horizontal moving motor 18. A horizontal moving slider 21 is provided at the bottom of the horizontal moving seat 17. A horizontal moving rack 22 that meshes with the horizontal moving gear 20 and a horizontal moving slide rail 23 that cooperates with the horizontal moving slider 21 are provided on the crossbeam 16.

[0028] A vertical shift gear 24 is mounted on the output shaft of the vertical shift motor 19, and a vertical shift slider 25 is mounted on the rear side of the horizontal shift seat 17. A vertical shift rack 26 that meshes with the vertical shift gear 24 and a vertical shift slide rail 27 that cooperates with the vertical shift slider 25 are mounted on the vertical beam 46. When the horizontal shift motor 18 is started, it can drive the electromagnetic chuck 10 to move along the horizontal beam 16. When the vertical shift motor 19 is started, it can drive the electromagnetic chuck 10 to move vertically up and down.

[0029] The electromagnetic chuck 10 at the bottom of the vertical beam 46 picks up the channel steel. The combined weight of the channel steel and the vertical beam 46 itself is quite heavy. Relying solely on the meshing of the vertical shift gear 24 and the vertical shift rack 26 makes it difficult to achieve vertical movement limitation of the vertical beam 46. To solve this problem, a lifting cylinder 28 is installed between the horizontal shift seat 17 and the vertical beam 46. The cylinder body of the lifting cylinder 28 is fixed to the horizontal shift seat 17, and the piston rod of the lifting cylinder 28 is fixed to the bottom of the vertical beam 46. The lifting cylinder 28 consistently applies an upward force to the vertical beam 46 to balance the lifting weight, resulting in smoother lifting and lowering without starting impact.

[0030] Furthermore, in order to enable the electromagnetic chuck 10 to adapt to different types of channel steel, and to allow the electromagnetic chuck 10 to adaptively pick up materials based on the surface undulations of the channel steel, such as... Figure 9 As shown, a long frame 29 is installed at the bottom of the vertical beam 46. The long frame 29 is arranged parallel to the length direction of the conveyor frame 1. Several hanging racks 30 are installed along the length direction of the long frame 29, and each hanging rack 30 is equipped with an electromagnetic chuck 10.

[0031] The electromagnetic chuck 10 has an upper support rod 31. One end of the support rod 31 extends upward through the mounting bracket 30 and is fitted with a limiting bolt 32 to limit the downward movement of the electromagnetic chuck 10 relative to the mounting bracket 30. A first spring 33 is fitted around the outer periphery of the support rod 31 between the mounting bracket 30 and the electromagnetic chuck 10. The first spring 33 always tends to push the electromagnetic chuck 10 downward away from the mounting bracket 30. When the electromagnetic chuck 10 comes into contact with the surface of the channel steel, if the surface of the channel steel is uneven, the elastic force of the first spring 33 can be overcome to keep the electromagnetic chuck 10 in close contact with the surface of the channel steel, thereby achieving stable gripping of the channel steel.

[0032] The bottom of the long frame 29 is also equipped with a sleeve 34, inside which a retractable detection rod 35 is fitted. A second spring 36 is installed between the detection rod 35 and the sleeve 34, and the second spring 36 always tends to push the detection rod 35 down past the electromagnetic chuck 10. The detection rod 35 is designed to detect whether there is a channel steel at the bottom of the electromagnetic chuck 10. When the detection rod 35 contacts the channel steel, it indicates that the channel steel is in place, and then the electromagnetic chuck 10 can be energized. The electromagnetic chuck 10 moves down to pick up the channel steel.

[0033] When the clamping cylinder 7 clamps the channel steel, since the channel steel is located on the conveying roller 2, the conveying roller 2 will not stop rotating immediately during clamping, and the channel steel will move a short distance. This may cause the channel steel to separate from the clamping cylinder 7. In order to avoid the above situation and allow the channel steel to be separated from the conveying roller 2 when clamped, the conveying frame 1 is equipped with a channel steel lifting mechanism, which can lift the channel steel upward away from the conveying roller 2.

[0034] like Figure 10As shown, the channel steel lifting mechanism includes a lifting shaft 37 mounted on the conveyor frame 1, and a lifting frame 38 mounted on the lifting shaft 37. The lifting frame 38 is a rotating structure with one end longer and the other end shorter. When the lifting frame 38 rotates, the longer end contacts the channel steel and pushes the channel steel away from the conveyor roller 2. When the longer end is in a horizontal position, the entire lifting frame 38 can be located in the space below the top of the conveyor roller 2 without interfering with the normal transfer of the channel steel.

[0035] To drive the lifting shaft 37, a rocker arm 39 is mounted on one end of the shaft, and a lifting cylinder 40 is installed between the rocker arm 39 and the conveyor frame 1. The cylinder body of the lifting cylinder 40 is hinged to the conveyor frame 1, and the piston rod of the lifting cylinder 40 is hinged to the end of the rocker arm 39 away from the lifting shaft 37. The extension and retraction of the piston rod of the lifting cylinder 40 can drive the lifting frame 38 to swing back and forth, thereby lifting the channel steel off the conveyor roller 2.

[0036] When the clamping cylinder 7 clamps and flips the channel steel, the fixed clamping plate 8 and the movable clamping plate 9 only clamp the side of the channel steel through friction, without vertical restraint. During the flipping process, insufficient friction can cause the clamped channel steel to move or even fall, making subsequent positioning and stacking impossible. To solve this problem and achieve vertical restraint for channel steel of different heights, preventing movement or falling during the flipping process, such as... Figure 11 and Figure 12 As shown, several clamping and limiting mechanisms arranged along the height direction are installed in both the fixed clamping plate 8 and the movable clamping plate 9.

[0037] Each clamping and limiting mechanism includes a limiting post 41, a protruding edge 42 on the limiting post 41, and a sliding groove 43 that mates with the protruding edge 42 is provided in the clamping plate. The end of the sliding groove 43 is provided with a buckle 44 that allows the limiting post 41 to extend. A third spring 45 is installed between the protruding edge 42 and the sliding groove 43. The third spring 45 always tends to allow the limiting post 41 to extend out of the sliding groove 43.

[0038] When the channel steel moves to the positions of the fixed clamping plate 8 and the movable clamping plate 9, the movable clamping plate 9 moves closer to the fixed clamping plate 8. Under the squeezing action of the clamping plates, the limiting posts 41 at the level with and below the channel steel overcome the elastic force of the third spring 45 and enter the slide groove 43. The limiting posts 41 located at the upper part of the channel steel will form a vertical limit on the channel steel. Even during the flipping process, the channel steel will be vertically limited by the limiting posts 41, ensuring that the channel steel can be positioned and moved to the desired stacking position. Several clamping and limiting mechanisms arranged along the height direction of the clamping plates can adapt to channel steel of different heights, thereby improving the applicability of the overall device.

[0039] The automatic flipping and palletizing mechanism for channel steel described in this utility model also has the following advantages:

[0040] Enhanced equipment flexibility: The installation of the horizontal movement motor 18 and the vertical movement motor 19 enables the electromagnetic chuck 10 to move flexibly between the conveyor frame 1, the flipping temporary storage frame 3 and the discharge trolley 4, adapting to the stacking requirements of channel steel of different specifications and sizes, and enhancing the versatility and flexibility of the equipment.

[0041] Improve equipment stability: The lifting cylinder 28, the first spring 33 and the third spring 45 are respectively used to lift the vertical beam 46, the contact between the buffer electromagnetic chuck 10 and the channel steel, and the channel steel in the limiting clamping plate. These designs improve the stability and reliability of the equipment during operation and reduce the failure rate.

[0042] Easy to maintain and repair: The channel steel lifting mechanism allows the channel steel to be lifted away from the conveyor roller 2 when needed, which facilitates the maintenance and repair of the conveyor roller 2 and extends the service life of the equipment.

[0043] Optimized structural design: The design of components such as the mounting bracket 30, limit bolt 32, and detection rod 35 not only facilitates the installation and replacement of the electromagnetic chuck 10, but also allows for real-time monitoring of the working status of the electromagnetic chuck, ensuring the smooth progress of the palletizing process.

[0044] The automatic flipping and palletizing mechanism for channel steel integrates a flipping mechanism and a suction cup palletizing mechanism, realizing the automatic flipping and palletizing of channel steel. It has the advantages of high automation, high operating efficiency, good safety, high palletizing quality and space saving. It is suitable for mass production and palletizing operations of channel steel and has broad application prospects.
