Description

Technical Field

[0001] This invention relates to the field of steel pipe production equipment technology, and in particular to a sorting system for steel pipes. Background Technology

[0002] After the steel pipes are manufactured, they need to be removed from the production line and stored. This process requires conveying and classifying the steel pipes. Currently, the conveying of steel pipes after they come off the production line is done manually by moving them to forklifts or other equipment, and then manually unloading them into the storage area. In the classification and storage stage, different types of steel pipes are manually identified and stacked in different areas. The sorting operation is separated from the conveying operation. The sorting process involves a lot of manual intervention and is labor-intensive. In addition, different types of steel pipes are prone to being mixed up in the storage area. Summary of the Invention

[0003] To improve the efficiency of steel pipe transportation and sorting, this application provides a sorting system for steel pipes.

[0004] The sorting system for steel pipes provided in this application adopts the following technical solution: A sorting system for steel pipes includes: a feeding mechanism comprising a loading rack, the output end of which is provided with a feeding component, and the output end of which is provided with a steel pipe conveying track; a shaping mechanism disposed on the steel pipe conveying track, the shaping mechanism including shaping wheels near or away from the steel pipe conveying track, the shaping wheels pressing the steel pipes against the steel pipe conveying track; a detection mechanism disposed on the steel pipe conveying track and located on the side of the shaping mechanism away from the feeding mechanism, the detection mechanism being used to detect the steel pipes; and a sorting mechanism, the output end of the steel pipe conveying track corresponding to the input end of the sorting mechanism, the sorting mechanism including a first storage bin and a second storage bin, the sorting mechanism having a sorting component, the sorting component conveying the steel pipes to the first storage bin or the second storage bin according to the detection results.

[0005] By adopting the above technical solution, the feeding assembly feeds the steel pipes into the steel pipe conveying track. The shaping wheels press the steel pipes firmly against the conveying track, applying a corrective force to the moving pipes and maintaining their straight-line travel. The inspection mechanism performs eddy current testing on the corrected steel pipes, using the principle of electromagnetic induction to detect defects such as cracks and porosity on and near the surface of the pipes, generating inspection results. The sorting assembly, based on the inspection results, conveys the steel pipes to either the first or second storage bin, achieving automatic sorting of the steel pipes according to the eddy current testing results, forming a fully automated process from feeding to sorting.

[0006] Optionally, the upper surface of the material carrier is inclined, with the upward inclined side of the material carrier being the input end and the downward inclined side being the output end. The feeding component includes a limiting component and a lifting component. The limiting component protrudes from the upper surface of the material carrier and is positioned towards the input end of the material carrier. The output end of the lifting component is raised and lowered, and the lifting component lifts and transfers the steel pipe at the limiting component to the output end side of the material carrier.

[0007] By adopting the above technical solution, the steel pipes automatically roll towards the output end under the action of gravity, achieving continuous feeding. A limiting component protrudes from the upper surface of the material carrier and faces the input end. When the steel pipes roll, they are stopped by the limiting component, preventing all the steel pipes from sliding out at once. A lifting component is designed to lift and transfer the steel pipes at the limiting component to the output end of the material carrier, realizing the separation and output of the steel pipes one by one from a stacked state. The limiting component and the lifting component work together to transfer only one steel pipe at a time, avoiding blockages.

[0008] Optionally, the lifting assembly includes a top plate with a lifting mechanism, and the limiting assembly includes a limiting block disposed on the side facing the input end of the material rack, with the side of the top plate facing the input end of the material rack protruding beyond the side of the limiting block facing the input end of the material rack.

[0009] By adopting the above technical solution, when the steel pipe is blocked by the limiting block, it is located on the side of the limiting block facing the input end. During the process of the top plate rising, it first contacts the lowest point of the steel pipe and lifts the steel pipe upward. When the steel pipe is lifted to a height exceeding that of the limiting block, the steel pipe passes over the limiting block and rolls towards the output end. The position of the side of the top plate and the side of the limiting block are staggered, realizing the separation of a single steel pipe.

[0010] Optionally, the limiting component further includes an adjusting component, which drives the limiting block to reciprocate along the tilting direction of the material carrier, and a feeding space is formed between the side of the top plate facing the input end of the material carrier and the side of the limiting block facing the input end of the material carrier.

[0011] By adopting the above technical solution, a feeding space is formed between the side of the top plate facing the input end and the side of the limiting block facing the input end. The size of the feeding space is determined by the position of the limiting block. The operation adjustment component drives the limiting block to move, changing the distance between the side of the limiting block and the side of the top plate, so that the width of the feeding space matches the diameter of the steel pipe to be sorted. This allows the feeding component to adapt to steel pipes of various specifications, improving the versatility of the system.

[0012] Optionally, the steel pipe conveying track includes multiple sets of spaced transmission rollers, and the transmission rollers are located below the shaping rollers, with the shaping rollers pressing the steel pipes onto the transmission rollers.

[0013] By adopting the above technical solution, the pressure applied by the shaping wheel forces the steel pipe to fit against the upper surface of the transmission roller. The cylindrical profile of the transmission roller is used to radially constrain the steel pipe, and the axis of the steel pipe is corrected to be parallel to the conveying direction.

[0014] Optionally, the shaping mechanism includes a machine base, the transmission rollers are arranged on both sides of the machine base, the steel pipe passes through the middle of the machine base, the machine base is equipped with sensors corresponding to the steel pipe, the shaping wheel is connected to the output end of the shaping drive component, and the sensor is electrically connected to the shaping drive component.

[0015] By adopting the above technical solution, the machine is equipped with a sensor corresponding to the steel pipe. When the steel pipe moves to the sensor position, the sensor generates a trigger signal. The forming wheel is connected to the output end of the forming drive component. The sensor is electrically connected to the forming drive component. The trigger signal is transmitted to the forming drive component, and the drive component responds to the signal to drive the forming wheel to move downward, pressing the steel pipe against the transmission roller, thereby realizing the automatic triggering of the forming action.

[0016] Optionally, the shaping mechanism includes a lifting platform that is vertically mounted on the machine base, and the shaping drive component is mounted on the lifting platform.

[0017] By adopting the above technical solution, when the lifting platform rises or falls relative to the machine base, the shaping drive component fixed on the lifting platform and the shaping wheel connected to the output end of the shaping drive component rise and fall synchronously, changing the distance between the shaping wheel and the transmission roller below. This distance determines the height of the shaping space. The lifting platform allows the height of the shaping wheel to be adjusted according to the diameter of the steel pipe, enabling the shaping mechanism to adapt to various pipe diameters and expanding the processing range of the system.

[0018] Optionally, the output end of the steel pipe conveying track is positioned above the first storage bin, and the second storage bin is positioned on the side of the first storage bin away from the steel pipe conveying track. The upper surface of the first storage bin is inclined downward from the side near the steel pipe conveying track towards the second storage bin. The opening of the second storage bin is positioned on the upper surface of the first storage bin. The opening of the first storage bin is located on the upper surface, and the sorting component is configured to movably open and close the opening of the first storage bin.

[0019] By adopting the above technical solution, the steel pipe falls from the output end of the track and lands on the upper surface of the first storage bin. The second storage bin is located on the side of the first storage bin away from the steel pipe conveying track. The upper surface of the first storage bin is inclined downwards from the side closest to the track towards the second storage bin, and the steel pipe rolls towards the second storage bin under the action of gravity. The sorting component movably opens and closes the opening of the first storage bin. When the opening of the first storage bin is open, the steel pipe enters the first storage bin; when the opening of the first storage bin is closed, the steel pipe enters the second storage bin, thereby realizing the diversion and storage of the steel pipe.

[0020] Optionally, the sorting assembly includes a rotatably mounted sealing block, the shaft of which is located on the upper surface of the first storage bin at an angle downwards. When the sealing block closes the opening of the first storage bin, the upper surface of the sealing block is flush with the upper surface of the first storage bin.

[0021] By adopting the above technical solution, the sealing block rotates around the axis. When rotating upwards, it opens the opening of the first storage bin, allowing the steel pipe to fall into it; when rotating downwards, it closes the opening. When the sealing block closes the opening, its upper surface is flush with the upper surface of the first storage bin. When the steel pipe rolls from the upper surface of the first storage bin to the upper surface of the sealing block, because the two surfaces are flush and there are no steps or gaps, the steel pipe can smoothly pass the opening and roll towards the second storage bin, eliminating the risk of jamming.

[0022] Optionally, the output end of the steel pipe conveying track is provided with a flipping and unloading device, which includes multiple parallel flipping and unloading arms. The multiple flipping and unloading arms are connected to the same rotating shaft. The end of the flipping and unloading arm away from the rotating shaft is folded upward in an L-shape. The multiple flipping and unloading arms are intermittently embedded in the steel pipe conveying track.

[0023] By adopting the above technical solution, the end of the tilting and unloading arm away from the rotating shaft is folded upward into an L-shape, forming an upwardly bent hook-shaped receiving surface. Multiple tilting and unloading arms are intermittently embedded in the steel pipe conveying track. In the initial state, the upper surface is not higher than the track conveying surface. After the steel pipe is in place, the rotating shaft drives the tilting and unloading arm to tilt upward. The L-shaped bent end lifts the steel pipe from below and raises it upward. The steel pipe slides down from the inclined side of the L-shaped bent end into the storage bin.

[0024] In summary, this application includes at least one of the following beneficial effects: 1. A limiting component protrudes from the upper surface of the material carrier and faces the input end, preventing all steel pipes from sliding out at once. A lifting component, with its vertical movement, elevates and transfers the individual steel pipes at the limiting component to the output end, completing the separation process from stacking. An adjusting component drives the limiting block to move along an inclined direction, changing the width of the feeding space between the side of the top plate and the side of the limiting block, thus matching the feeding space to steel pipes of different diameters. This combination of structures enables automatic feeding of steel pipes one by one, avoiding blockages caused by multiple steel pipes entering the track simultaneously, and improving the versatility and reliability of the feeding process.

[0025] 2. When the steel pipe moves to the sensor position, a trigger signal is generated. The forming drive responds to the signal and drives the forming wheel downwards, automatically pressing the steel pipe against the transmission roller, ensuring that each steel pipe receives consistent straightening pressure. The lifting platform is mounted on the machine base, and the forming drive is mounted on the lifting platform. As the lifting platform rises and falls, the forming wheel rises and falls synchronously, changing the distance between the forming wheel and the transmission roller. This distance determines the height of the forming space and can be adjusted according to the steel pipe diameter, allowing the forming mechanism to adapt to various pipe diameters. This automates the straightening action and expands the system's processing range.

[0026] 3. The upper surface of the first storage bin is inclined downwards from the side closest to the track towards the second storage bin. After the steel pipe falls, it rolls along the inclined upper surface. The sorting assembly includes a rotating sealing block, whose shaft is located on the inclined downward side of the upper surface of the first storage bin. When the sealing block closes the opening, its upper surface is flush with the upper surface of the first storage bin. When the sealing block rotates upwards, it opens the opening, and the steel pipe falls into the first storage bin; when it rotates downwards, it closes the opening, and the flush surface allows the steel pipe to smoothly roll over the opening to the second storage bin. The flush joint surface eliminates the risk of jamming when the steel pipe rolls, achieving smooth diversion of the steel pipe. The structure is simple and the sorting is reliable.

[0035] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0036] This application discloses a sorting system for steel pipes. (Refer to...) Figure 1 The system includes a steel pipe conveying track 2, and a feeding mechanism 1, a shaping mechanism 3, an inspection mechanism 4, and a sorting mechanism 5 are arranged sequentially along the output direction of the steel pipe conveying track 2. This application also includes a control system (not shown), which is electrically connected to the inspection mechanism 4 and the sorting drive 533, and is used to receive inspection signals and control the actuators. The steel pipes are placed onto the steel pipe conveying track 2 via the feeding mechanism 1, then sequentially shaped by the shaping mechanism 3, inspected by the inspection mechanism 4, and finally output to the sorting mechanism 5 for sorting and storage of good and defective steel pipes. In this embodiment, the inspection mechanism 4 is an eddy current detection device, which uses the electromagnetic induction principle in the prior art to excite eddy currents on the surface of the steel pipe. The changes in eddy currents are used to detect defects such as cracks and pores on and near the surface of the steel pipe. The feeding mechanism 1, shaping mechanism 3, inspection mechanism 4, and sorting mechanism 5 are arranged sequentially along the steel pipe conveying track 2, forming a unidirectional linear process from placement to output, with no cross-interference between the various stages. The testing agency 4 uses eddy current testing equipment, which uses the principle of electromagnetic induction to detect defects on and near the surface of the steel pipe in a non-contact manner. This ensures that the testing speed matches the conveying rhythm and avoids scratches on the surface of the steel pipe caused by contact testing.

[0037] In a preferred embodiment, refer to Figure 2 and 3The feeding mechanism 1 includes a loading frame 11, which is inclined, with the downward-sloping side of the loading frame 11 facing the steel pipe conveying track 2. In this embodiment, the portion of the loading frame 11 near the steel pipe conveying track 2 is inclined. The loading frame 11 is composed of multiple parallel support beams 111 spaced apart. The inclined side of the support beam 111 is the output end, and the horizontal side of the support beam 111 is the input end. The steel pipes on the loading frame 11 are placed perpendicular to the multiple support beams 111. The feeding assembly 12 is located in the middle of the inclined section of the loading frame 11. The feeding assembly 12 includes a limiting assembly 121 and a lifting assembly 122. The limiting assembly 121 includes multiple limiting blocks 1211, which are arranged according to the number of support beams 111 and located between two adjacent support beams 111. The upper end of the limiting block 1211 protrudes from the upper surface of the support beam 111, thereby intercepting the steel pipes on the loading frame 11. The material carrier 11 consists of multiple parallel support beams 111 spaced apart. The steel pipes are placed vertically across the support beams 111, and the multi-point support ensures that the long steel pipes are evenly stressed, preventing bending and deformation. The inclined section of the support beam 111 allows the steel pipes to roll automatically towards the output end, while the horizontal section facilitates the manual or mechanical placement of steel pipes in batches. The combination of the two sections balances the convenience of loading and the continuity of material supply.

[0038] In a preferred embodiment, refer to Figures 2 to 4 The lifting assembly 122 includes multiple top plates 1221, which are raised and lowered. The number of top plates 1221 corresponds to the number of support beams 111, and they are located between two adjacent support beams 111. The top plates 1221 are located on the side of the limiting block 1211 near the input end of the support beam 111. In the initial state, the top plates 1221 are located between two support beams 111 and are lower than the upper surface of the support beams 111 in the height direction. After being raised, the upper end of the top plates 1221 is higher than the upper end of the limiting block 1211, and the upper end of the top plates 1221 is parallel to the upper surface of the support beams 111. After being raised, the steel pipe crosses the limiting block 1211 and rolls along the support beams 111 into the steel pipe conveying track 2.

[0039] In a preferred embodiment, refer to Figures 2 to 4 The limiting assembly 121 also includes an adjusting assembly, which includes an adjusting shaft 1212 and a gearbox assembly 1213. The gearbox assembly 1213 is connected to a turntable 1214, and one end of each of the multiple limiting blocks 1211 is sleeved on the adjusting shaft 1212. By adjusting the gearbox assembly 1213 through the turntable 1214, the adjusting shaft 1212 is rotated, causing the limiting blocks 1211 to rotate around the adjusting shaft 1212, thereby changing the relative position of the limiting blocks 1211 and the top plate 1221, and thus adjusting the distance between the side of the top plate 1221 near the input end of the support beam 111 and the contact surface between the limiting blocks 1211 and the steel pipe. This allows the top plate 1221 to be raised only one steel pipe at a time, depending on the pipe diameter, preventing multiple steel pipes from being simultaneously fed into the steel pipe conveying track 2 and causing a conveying blockage.

[0040] In a preferred embodiment, refer to Figures 2 to 4 The lifting assembly 122 includes a lifting drive component 1222. The output end of the lifting drive component 1222 is connected to the lifting shaft 1223 via a connecting rod. Multiple swing arms are fitted onto the lifting shaft 1223 corresponding to each top plate 1221. The swing arms are hinged to the lower end of the top plate 1221. The top plate 1221 is adjacent to the side of the support beam 111. A lifting slider 1224 is connected to the top plate 1221. A vertically arranged lifting slide rail 1225 is provided on the side of the support beam 111, and the lifting slider 1224 is slidably mounted on the lifting slide rail 1225. In this embodiment, the lifting drive component 1222 is a cylinder assembly. The lifting drive component 1222 drives the lifting shaft 1223 to rotate. The connecting rod drives the lifting shaft 1223 to rotate, and the multiple swing arms on the shaft synchronously push each top plate 1221 vertically up and down along the lifting slide rail 1225. Multiple sets of top plates 1221 are linked by the same rotating shaft to ensure that all top plates 1221 are raised and lowered at the same height. When the long steel pipe is lifted, both ends are synchronized, and there will be no situation where one end is higher than the other.

[0041] In a preferred embodiment, refer to Figure 2 and 3 The steel pipe conveying track 2 includes multiple sets of spaced-apart drive rollers 21. The steel pipe is conveyed by rolling on these rollers, which are synchronously driven by sprockets as is common in the prior art. Preferably, a positioning block 23 is provided on the side of the steel pipe conveying track 2 connected to the feeding mechanism 1, away from the support beam 111. The multiple sets of drive rollers 21 are arranged at intervals, allowing the long steel pipe to roll simultaneously on multiple rollers. The distance between the rollers is less than the length of the steel pipe, preventing the middle of the pipe from sag and bend. The synchronous drive by the sprockets ensures that all drive rollers 21 have the same linear speed, preventing twisting due to speed differences during steel pipe conveying.

[0042] In a preferred embodiment, refer to Figure 5The shaping mechanism 3 includes a machine base 32 mounted on a steel pipe conveying track 2, with transmission rollers 21 positioned on both sides of the machine base 32, and the steel pipe passing through the middle of the machine base 32. A sensor 33 is mounted on the machine base 32, corresponding to the steel pipe. In this embodiment, the machine base 32 has two shaping drive components 34, with their output ends facing downwards. A shaping wheel 31 is rotatably mounted on the output section of the shaping drive component 34, and the two shaping wheels 31 are positioned corresponding to the transmission rollers 21 on both sides of the machine base 32. The shaping drive components 34 drive the shaping wheels 31 to move closer to or further away from the transmission rollers 21 on both sides of the machine base 32, pressing the steel pipe firmly onto the transmission rollers 21 to correct its shape. The sensor 33 triggers the shaping drive component 34 when the steel pipe arrives, preventing the shaping wheel 31 from being under-pressurized or prematurely pressing down before the steel pipe reaches its destination. The two shaping rollers 31 are arranged to correspond to the transmission rollers 21 on both sides of the machine base 32. When the steel pipe is pressed, the left and right sides are subjected to force at the same time, and the corrective force is symmetrically distributed to prevent the steel pipe from being pressed off-center.

[0043] In a preferred embodiment, refer to Figure 5 The machine base 32 is equipped with a lifting platform 35. A shaping drive component 34 is mounted on the lifting platform 35. A shaping wheel 31 is connected to a swing arm, which is rotatably mounted on the lifting platform 35. A lifting screw 351 is rotatably mounted on the lifting platform 35, with its upper end passing through and threadedly connected to the machine base 32. A lifting handwheel 352 is mounted on the upper end of the lifting screw 351. The shaping drive component 34 is mounted on the lifting platform 35, and the shaping wheel 31 is rotatably mounted on the platform via the swing arm. The lifting platform 35 drives the shaping drive component 34 and the swing arm to rise and fall as a whole without changing the swing angle of the swing arm. This design ensures that the relative pressing angle between the shaping wheel 31 and the transmission roller 21 remains unchanged when adjusting the height, only altering the height of the shaping space, adapting to different pipe diameters while maintaining consistent pressing posture.

[0044] In a preferred embodiment, refer to Figure 5 There are two shaping mechanisms 3, located on both sides of the detection mechanism 4. The steel pipe passes sequentially through the first shaping mechanism 3, the detection mechanism 4, and the second shaping mechanism 3 on the steel pipe conveying track 2. The first shaping mechanism 3 pre-corrects the steel pipe before it enters the detection mechanism 4, eliminating bending deformations that occur during the conveying process and ensuring the steel pipe enters the eddy current detection equipment in a straight position. This avoids fluctuations in the distance between the detection probe and the pipe wall caused by pipe bending, which could affect detection accuracy. The second shaping mechanism 3 corrects the steel pipe again after detection, ensuring it remains straight when entering the sorting mechanism 5, facilitating a smooth drop into the storage bin.

[0045] In a preferred embodiment, refer to Figure 6 and 7The system comprises a first storage bin 51 and a second storage bin 52. The first storage bin 51 is located near the steel pipe conveying track 2, and the second storage bin 52 is located on the side of the first storage bin 51 away from the steel pipe conveying track 2. The upper surface of the first storage bin 51 slopes downward from the side near the steel pipe conveying track 2 toward the second storage bin 52. The upper surface of the first storage bin 51 includes two rows of guide blocks 511, each row comprising multiple parallel and spaced guide blocks 511. The opening of the first storage bin 51 faces upward between the two rows of guide blocks 511, and the opening of the second storage bin 52 also faces upward. A sorting component 53 is provided at the opening of the first storage bin 51, which movably opens and closes the opening of the first storage bin 51. The upper surface of the first storage bin 51 slopes toward the second storage bin 52, utilizing gravity to automatically roll the steel pipe toward the second storage bin 52 without requiring additional power. When the opening of the first storage bin 51 is opened, the steel pipe enters the first storage bin 51. When the opening of the first storage bin 51 is closed, the steel pipe enters the second storage bin 52, thereby realizing the diversion and storage of steel pipes.

[0046] In a preferred embodiment, refer to Figure 6 and 7 The sorting assembly 53 includes multiple rotatably arranged closing blocks 531. Multiple closing blocks 531 are spaced apart from guide blocks 511 and arranged parallel to each other. Two adjacent rows of guide blocks 511 are arranged at each end of each closing block 531. The multiple closing blocks 531 are sleeved on a sorting shaft 532, which is located on the side of the first storage bin 51 away from the steel pipe conveyor track 2. A connecting rod is sleeved on the sorting shaft 532, and the connecting rod is connected to the output end of the sorting drive component 533. In this embodiment, the sorting drive component 533 is a cylinder assembly. When the closing blocks 531 rotate downwards around the sorting shaft 532, the front end of the closing blocks 531 presses against the edge of the opening, closing the opening of the first storage bin 51. When the closing blocks 531 rotate upwards around the sorting shaft 532, the front end of the closing blocks 531 lifts, opening the opening of the first storage bin 51. The sorting drive component 533 drives the sorting shaft 532 to rotate. The sealing block 531 is fitted onto the same sorting shaft 532 to achieve synchronous rotation, ensuring that all sealing blocks 531 open or close simultaneously when the long steel pipe passes by, and that no partial opening occurs that would prevent the steel pipe from entering the first storage bin 51.

[0047] In a preferred embodiment, refer to Figure 6 and 7Both the first storage bin 51 and the second storage bin 52 have elastic fabric strip layers 54 below their openings. The elastic fabric strip layers 54 are fixed at both ends to the side walls of the bin body, with the middle section hanging down naturally. When the steel pipe falls in, the elastic fabric strip layer 54 undergoes elastic deformation to absorb impact energy, reducing the noise generated by the collision between the steel pipe and the metal at the bottom of the bin, while also preventing new scratches or dents from forming on the surface of the steel pipe due to hard impact. The elastic fabric strip layer 54 also has a buffering effect; the steel pipe falling in first sinks into the elastic fabric strip layer 54, and the steel pipe falling later lands on top of it, forming soft contact and reducing mutual collision damage between the steel pipes.

[0048] In a preferred embodiment, refer to Figure 6 and 7 The output end of the steel pipe conveying track 2 is equipped with a tilting and unloading device 22, which includes multiple parallel tilting and unloading arms 221. These arms are connected to the same tilting shaft 222. The end of each arm 221 away from the shaft is folded upwards in an L-shape. The arms are spaced apart and embedded in the steel pipe conveying track 2. A connecting rod is sleeved on the tilting shaft 222, and the connecting rod is connected to the output end of a tilting drive component 223. In this embodiment, the tilting drive component 223 is a cylinder assembly. The tilting drive component 223 drives the tilting shaft 222 to rotate. With the tilting and unloading arms 221 spaced apart and embedded in the steel pipe conveying track 2, initially, the upper surface of the arm is not higher than the conveying surface of the track, allowing the steel pipe to roll unimpeded from the track to above the tilting and unloading arms 221. Multiple tilting and unloading arms 221 are connected to the same tilting shaft 222 and tilt synchronously. The L-shaped bent end lifts the steel pipe from below and raises it upward. Under the action of gravity, the steel pipe slides down from the inclined side of the bent end.

[0049] The above are all preferred embodiments of this application. These embodiments are merely explanations of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of this application should be covered within the scope of protection of this application.
