Description

Technical Field

[0001] This invention relates to the field of automated pipe feeding and conveying equipment, specifically a steel pipe feeding machine. Background Technology

[0002] In automated steel pipe processing, cutting, grinding, and conveying production lines, the orderly and automated feeding of steel pipes is an important preliminary process for continuous operation. Currently, most traditional steel pipe feeding equipment on the market uses a storage box combined with a simple pushing structure to push the steel pipes up. After being pushed up, the steel pipes roll freely down a fixed slope onto the conveyor belt, thus achieving continuous feeding operations.

[0003] Existing technologies still have many shortcomings in practical use: First, traditional feeding structures lack reliable buffer and protection structures. The steel pipes are heavy and roll at high speed under gravity, resulting in strong impact force. This can easily cause quality defects such as dents, paint peeling, and deformation at the pipe ends and outer walls, seriously affecting the quality of finished steel pipes. At the same time, frequent high-intensity impacts of steel pipes on the conveyor belt can easily accelerate belt wear, loosening, or even deviation, significantly reducing the service life of the conveyor belt and increasing equipment maintenance costs.

[0004] Secondly, the existing equipment has no restraint or buffer during the rolling process of the steel pipes. The steel pipes are prone to bouncing, deflection, and skewed posture when rolling, which makes it impossible for the steel pipes to land smoothly and neatly on the surface of the conveyor belt. This can easily lead to problems such as conveying jams and misaligned conveying. The adaptability and stability are poor, making it difficult to meet the needs of modern mass production, high precision, and stable feeding of steel pipes.

[0005] Therefore, there is an urgent need to design a steel pipe feeding machine with a reasonable structure, buffer protection, and the ability to avoid the problem of steel pipe impact and stacking, so as to solve many technical defects in the existing technology. Summary of the Invention

[0006] The purpose of this invention is to provide a steel pipe feeding machine to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A steel pipe feeding machine includes: a material box and a fixed plate. The fixed plate is installed at the bottom of one end of the material box. Two guide plates are installed on the top of the fixed plate. A feeding mechanism for pushing a single steel pipe upward and onto the top of the two guide plates is provided below the material box. A movable frame is provided at the end of the fixed plate away from the material box. A buffer mechanism for buffering and protecting the steel pipe rolling downward to the top of the conveyor belt is provided inside the movable frame.

[0008] As a further embodiment of the present invention: multiple support pillars are installed at the bottom of the material box, and a base plate is installed between the multiple support pillars, with the feeding mechanism installed on top of the base plate.

[0009] As a further embodiment of the present invention: the feeding mechanism includes a power unit, which is installed on the top of the base plate. Multiple telescopic ends of the power unit are jointly equipped with a feeding frame. The bottom of the material box has two movable slots for vertical movement of the feeding frame, and the top of the feeding frame has two U-shaped slots for placing steel pipes.

[0010] As a further embodiment of the present invention: both guide plates are installed on the top of the fixed plate in an inclined state, with the lower end of the two guide plates close to the moving frame.

[0011] As a further embodiment of the present invention: a rotating groove is provided inside the higher end of each of the two guide plates, and a rotating guide rod is rotatably installed inside each of the two rotating grooves via a rotating shaft.

[0012] As a further embodiment of the present invention: an installation groove is provided inside the end of the fixed plate away from the material box, and a movable plate adapted to the installation groove is installed at the end of the movable frame close to the fixed plate. Electric telescopic rods are installed on both outer walls of the fixed plate, and the telescopic ends of the two electric telescopic rods are connected to the movable frame.

[0013] As a further embodiment of the present invention: the buffer mechanism includes multiple damping rods, one end of each damping rod is installed on the inner wall of one side of the movable frame, the other end of each damping rod is jointly installed with a buffer plate, springs are fitted on the outer sides of each damping rod, and a rubber pad is installed on the outer wall of the buffer plate away from the multiple damping rods.

[0014] As a further embodiment of the present invention: the bottom end of the movable frame is provided with a feeding port, a feeding plate is rotatably installed inside the feeding port, a drive motor is installed on one side of the outer wall of the movable frame, the output end of the drive motor is connected to the rotating part of one end of the feeding plate, and photoelectric sensors for detecting the position of the steel pipe falling on the top of the feeding plate are installed at both ends inside the movable frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the buffer mechanism effectively solves the technical problems of large impact when the steel pipe is dropped, easy collision of pipes, easy wear of the conveyor belt, and easy stacking of steel pipes by impact. At the same time, the horizontally adjustable movable frame structure can flexibly change the drop point of the steel pipes, so that the continuously fed steel pipes form a staggered arrangement on the conveyor belt, effectively avoiding collision between front and rear steel pipes, collision between steel pipes on both sides, and stacking blockage.

[0016] 2. In this invention, a feeding mechanism is used to stably lift and distribute individual steel pipes. Combined with a guide plate's self-weight rolling mechanism, this ensures orderly and stable steel pipe feeding. Furthermore, photoelectric detection and an automatic flipping unloading structure further improve the accuracy of unloading. The overall structure is tightly integrated and highly stable, effectively improving the regularity and continuity of steel pipe feeding, reducing the probability of equipment downtime, and meeting the stable operation requirements of large-scale, automated steel pipe production lines.

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0020] For reference Figures 1-7 As shown, a steel pipe feeding machine includes: a material box 1 and a fixed plate 2. The fixed plate 2 is installed at the bottom of one end of the material box 1. Two guide plates 8 are installed on the top of the fixed plate 2. A feeding mechanism for pushing a single steel pipe upward and onto the top of the two guide plates 8 is provided below the material box 1. A movable frame 10 is provided at the end of the fixed plate 2 away from the material box 1. A buffer mechanism for buffering and protecting the steel pipe rolling downward to the top of the conveyor belt is provided inside the movable frame 10.

[0021] In this embodiment, the material box 1 is used to stack steel pipes to be loaded, providing a storage station for the steel pipes; the fixed plate 2 serves as the mounting base, and a ramp track for the steel pipes to roll is formed between the two guide plates 8. The steel pipes can roll down along the track formed by the two guide plates 8; the loading mechanism is used to push the single steel pipe in the material box 1 upward, so that the steel pipe is lifted and falls to the top of the two guide plates 8. The steel pipe rolls down along the track formed by the two guide plates 8 by its own weight; after rolling down along the two guide plates 8, the steel pipe enters the area of ​​the moving frame 10. The buffer mechanism can buffer and protect the steel pipe that rolls to the top of the conveyor belt, weaken the impact generated by the rolling of the steel pipe, reduce the collision damage of the steel pipe, and at the same time reduce the impact of the steel pipe on the conveyor belt, prevent the steel pipe from bouncing and deviating, ensure that the steel pipe falls smoothly onto the conveyor belt, and improve the stability of equipment operation.

[0022] Multiple support columns 4 are installed at the bottom of the material box 1, and a base plate 5 is installed between the multiple support columns 4. The feeding mechanism is installed on the top of the base plate 5.

[0023] In this embodiment, multiple support columns 4 are arranged along the bottom of the material box 1, providing support and fixation for the material box 1, thus creating an elevated space at the bottom of the material box 1 for the loading mechanism to be installed. A base plate 5 is fixedly connected to each support column 4, with the support columns 4 bearing the load of the base plate 5 and its upper components. The base plate 5 provides a flat mounting reference surface for the loading mechanism, ensuring a fixed relative position between the loading mechanism and the material box 1, guaranteeing the positional accuracy of the loading mechanism during material pushing operations, preventing displacement of the loading mechanism, and ensuring stable execution of the pushing action.

[0024] The feeding mechanism includes a power unit 6, which is installed on the top of the base plate 5. Multiple telescopic ends of the power unit 6 are jointly equipped with a feeding rack 7. The bottom of the material box 1 has two movable slots 3 for vertical movement of the feeding rack 7, and the top of the feeding rack 7 has two U-shaped slots 15 for placing steel pipes.

[0025] In this embodiment, the power unit 6 has multiple telescopic ends, and the multiple telescopic ends of the power unit 6 are jointly equipped with the feeding frame 7. The multiple telescopic ends move synchronously, driving the feeding frame 7 to perform vertical lifting and lowering movements. During the lifting and lowering process, the feeding frame 7 can extend into the material box 1 through the movable groove 3 or retract below the material box 1. The movable groove 3 plays a role in avoiding the lifting and lowering movements of the feeding frame 7. The U-shaped slot 15 can limit and support the steel pipe, restricting the lateral displacement of the steel pipe during the lifting and lowering process, which facilitates the stable lifting of a single steel pipe.

[0026] In addition, the power unit 6 can adopt a multi-rod synchronous output drive component, specifically a multi-axis cylinder, a double-rod cylinder, a multi-group cylinder linkage assembly, or a multi-output end hydraulic cylinder; it can also adopt a multi-telescopic end electric drive assembly composed of a motor and a lead screw slide, which relies on multiple telescopic ends to jointly support the loading rack 7, ensuring that the lifting and lowering of the loading rack 7 is evenly stressed, and that the lifting and lowering process is not prone to tilting or jamming.

[0027] Both guide plates 8 are installed at an angle on top of the fixed plate 2, with the lower end of the two guide plates 8 close to the moving frame 10.

[0028] In this embodiment, the two guide plates 8 cooperate to form an inclined roller track for the steel pipe to roll. The higher end of the guide plate 8 is closer to the material box, and the lower end of the guide plate 8 is closer to the moving frame 10. After the steel pipe is lifted and falls onto the upper end of the two guide plates 8, it can rely on its own weight to roll along the inclined guide plates 8 to the lower end, completing the steel pipe transportation by its own weight, without the need for additional transportation drive components.

[0029] Both guide plates 8 have a rotating groove inside at one end, and a rotating guide rod 9 is installed inside each rotating groove via a rotating shaft.

[0030] In this embodiment, when the feeding rack 7 is at its lowest point, the steel pipe will slide to the top of the feeding rack 7; as the feeding rack 7 rises, it pushes a steel pipe that is inside the two U-shaped slots 15 upward together. As the feeding rack 7 continues to rise, the steel pipe abuts against and pushes the rotating guide rod 9 to rotate upward; when the steel pipe disengages from the rotating guide rod 9, the feeding rack 7 moves downward, the steel pipe falls to the top of the two rotating guide rods 9, and rolls down along the two rotating guide rods 9 onto the guide plate 8, and then is conveyed towards the conveyor belt via the guide plate 8.

[0031] The rotating guide rod 9 rotates around the rotating shaft. The rotating guide rod 9 can only rotate upwards, and the downward rotation is limited and constrained. The mass of the outer end of the rotating shaft of the rotating guide rod 9 is greater than the mass of the inner end of the rotating shaft, forming a counterweight structure. When the steel pipe is separated from the rotating guide rod 9, the rotating guide rod 9 automatically rotates back to its original position by its own counterweight, so as to carry out the next steel pipe splitting operation.

[0032] The fixed plate 2 has an installation groove inside at the end away from the material box 1. The movable frame 10 is equipped with a movable plate 17 that matches the installation groove at the end near the fixed plate 2. Electric telescopic rods 11 are installed on both outer walls of the fixed plate 2. The telescopic ends of the two electric telescopic rods 11 are connected to the movable frame 10.

[0033] In this embodiment, the movable plate 17 is embedded inside the mounting groove, which guides and limits the movable plate 17, allowing the movable frame 10 to slide along the fixed plate 2. By synchronously extending and retracting the electric telescopic rods 11 on both sides, the movable frame 10 is driven to move relative to the fixed plate 2, thereby changing the working position of the movable frame 10. If only a single device is set on one side of the conveyor belt, the position of the movable frame 10 at the top of the conveyor belt can be controlled by the telescopic ends of the two electric telescopic rods 11 during the steel pipe feeding process. This allows the falling point of the steel pipe to be adjusted, so that multiple steel pipes fall sequentially to the top of the conveyor belt in a staggered arrangement, effectively avoiding the situation where multiple steel pipes fall at the same point, eliminating the problems of collision, deformation, and jamming of steel pipes during the conveying process, ensuring orderly and stable conveying of steel pipes, and improving the overall feeding stability of the equipment.

[0034] The buffer mechanism includes multiple damping rods 21. One end of each damping rod 21 is installed on the inner wall of one side of the moving frame 10. The other end of each damping rod 21 is connected to a buffer plate 13. Springs 16 are fitted on the outer side of each damping rod 21. A rubber pad 20 is installed on the outer wall of the buffer plate 13 away from the damping rods 21.

[0035] In this embodiment, when the steel pipe rolls down and contacts the buffer plate 13, the spring 16 and the damping rod 21 work together to absorb energy and buffer, and the rubber pad 20 directly contacts the steel pipe, further reducing impact and friction damage.

[0036] In actual operation, two sets of feeding devices can be symmetrically arranged on both sides of the conveyor belt. When the steel pipes output from both sets of devices fall onto the surface of the conveyor belt simultaneously, they are prone to colliding with each other. This buffer mechanism can, on the one hand, block and isolate the steel pipes, reducing the risk of collision between the incoming materials from the two devices; on the other hand, it can decelerate and buffer the rolling steel pipes, allowing them to fall smoothly onto the top sides of the conveyor belt. Combined with the conveyor belt speed and the steel pipe feeding speed, it can also maintain a reasonable spacing between steel pipes fed out successively by the same device, preventing the tail end of one steel pipe from colliding with the head end of the next, thus achieving orderly material feeding. If the feeding device is only arranged on one side of the conveyor belt, the two electric telescopic rods 11 can be used to control the moving frame 10 to extend and retract back and forth on the top of the conveyor belt, which can also avoid the problem of collision between multiple steel pipes.

[0037] The bottom of the movable frame 10 is provided with a feeding port 19, and a feeding plate 14 is rotatably installed inside the feeding port 19. A drive motor 18 is installed on one outer wall of the movable frame 10. The output end of the drive motor 18 is connected to the rotating part of one end of the feeding plate 14. Both ends of the movable frame 10 are equipped with photoelectric sensors 12 for detecting the position of the steel pipe falling on the top of the feeding plate 14.

[0038] In this embodiment, the feeding plate 14 can rotate and open relative to the movable frame 10 to achieve the blocking and opening of the feeding port 19. The rotation angle of the feeding plate 14 can be precisely controlled by the forward and reverse rotation of the drive motor 18 to complete the automatic feeding and reset closing action. The through-beam photoelectric sensor 12 is used to detect the position of the steel pipe falling on the top of the feeding plate 14 in real time, accurately determining whether the steel pipe is fully in place and whether its posture is stable. Only when the sensor detects that the steel pipe is fully in place will the device trigger the drive motor 18 to operate, controlling the feeding plate 14 to rotate and open, so that the steel pipe falls stably from the feeding port 19, effectively avoiding problems such as the steel pipe not being in place, skewed feeding, jamming, and falling deviation, greatly improving the accuracy of steel pipe feeding and the stability of the automated operation of the equipment.

[0039] This invention relates to a steel pipe feeding machine. The machine integrates material storage, automatic single-pipe feeding, inclined roller feeding, adjustable position buffering, and photoelectric detection for automatic unloading, achieving automated and orderly steel pipe feeding. The specific working process is as follows: When the equipment is working, the steel pipes to be processed are stacked in the material box 1 to complete the storage. In the initial state, the power unit 6 drives the loading rack 7 to descend to the lowest position, and the steel pipes inside the material box 1 naturally slide down and fit into the U-shaped slot 15 at the top of the loading rack 7 to complete the positioning of the material to be picked up.

[0040] After the feeding operation is started, the multiple telescopic ends of the power unit 6 extend synchronously, pushing the feeding frame 7 vertically upward along the movable groove 3 at the bottom of the material box 1. The feeding frame 7 drives the steel pipes in the two U-shaped slots 15 to move upward synchronously. During the upward movement of the feeding frame 7, since the width of the two U-shaped slots 15 can only accommodate one steel pipe, only a single steel pipe remains at the top of the feeding frame 7, realizing the automatic single-pipe feeding function.

[0041] As a single steel pipe continues to rise with the feeding rack 7 and pushes against the rotating guide rod 9, the rotating guide rod 9 rotates upward under force, allowing the steel pipe to smoothly pass over it. After the steel pipe leaves contact, the rotating guide rod 9 automatically rotates back to its original position due to the gravity of the counterweight at the outer end of its shaft. Its structure prevents it from flipping downwards, ensuring that only a single steel pipe can be released at a time, thus continuously and stably completing the material distribution process. Subsequently, the power unit 6 drives the feeding rack 7 to descend and reset. The steel pipe naturally falls onto the surface of the reset rotating guide rod 9 and rolls smoothly downwards along the inclined roller track formed by the inclined guide plates 8, entering the moving frame 10.

[0042] After the steel pipe enters the moving frame 10, the buffer mechanism set inside the moving frame 10 buffers and protects the rolling steel pipe. When the steel pipe contacts the buffer plate 13, the elastic damping energy absorption effect of the damping rod 21 and the spring 16, combined with the flexible protection of the rubber pad 20, effectively reduces the impact of the rolling steel pipe and avoids the steel pipe from being bumped, deformed, bounced, or deviated. At the same time, it can be adapted to the working conditions of double-sided symmetrical feeding equipment to avoid the steel pipes on both sides colliding in the middle of the conveyor belt. It can also keep a safe distance between the front and rear steel pipes of a single machine feeding, and eliminate the phenomenon of head-to-tail collision and stacking jamming.

[0043] The steel pipe finally falls onto the feeding plate 14 at the bottom of the moving frame 10. The photoelectric sensors 12 at both ends of the moving frame 10 monitor the positioning status of the steel pipe in real time. Once the system detects that the steel pipe has completely and stably landed and is in a regular posture, the control system triggers the drive motor 18 to work. The drive motor 18 drives the feeding plate 14 to flip and open, and the steel pipe falls steadily onto the surface of the external conveyor belt through the feeding port 19. After the feeding is completed, the drive motor 18 drives the feeding plate 14 to rotate and reset, sealing the feeding port 19, waiting for the next steel pipe to be fed.

[0044] Meanwhile, the electric telescopic rods 11 on both sides of the fixed plate 2 can extend and retract synchronously according to production needs (this feeding device is only arranged on one side of the conveyor belt), driving the moving plate 17 to slide horizontally along the mounting groove of the fixed plate 2, causing the moving frame 10 to move laterally as a whole, and precisely adjusting the falling point of the steel pipe. This makes the continuously falling steel pipes on the conveyor belt form a staggered arrangement, completely avoiding the problems of steel pipe collision and material blockage caused by concentrated falling points, adapting to different feeding rhythms and conveying conditions, and greatly improving the stability and versatility of the automated feeding equipment.
