Description

Technical Field

[0001] This invention relates to the field of pipe fitting processing equipment technology, and in particular to an automatic pipe fitting feeding device. Background Technology

[0002] In the automated processing of pipes, such as cutting, chamfering, bending or threading, the pipes to be processed need to be transported to the processing station one by one in an orderly manner. Existing automatic pipe feeding devices usually use hoppers, lifting chains or vibratory feeders to sort and separate the pipes.

[0003] However, most feeding devices are designed for pipes of a single specification, i.e., a fixed diameter. When it is necessary to switch to pipes of different diameters, it is often necessary to manually adjust the width of the feed channel, replace the feeding components, or reset the control parameters. The adjustment process is cumbersome and may not be able to adapt to a large range of diameter changes. In addition, on the pipe rack, multiple pipes will naturally roll and come close to each other under the action of gravity, which can easily cause the pipes to stack up and down on the pipe rack, or squeeze and jam each other during the forward movement, making it impossible to achieve a stable one-by-one, close-fitting arrangement; thus affecting the continuity of automated processing.

[0004] Therefore, there is an urgent need to provide an automatic feeding device that can adapt to pipes of different diameters and achieve stable feeding and loading of pipes one by one, so as to solve the problems of poor adaptability, easy stacking and unreliable feeding of pipes one by one in the existing technology. Summary of the Invention

[0005] In order to adapt to pipes of different diameters and achieve stable feeding and loading of pipes one by one, this application provides an automatic pipe feeding device.

[0006] The automatic pipe fitting feeding device provided in this application adopts the following technical solution: An automatic pipe feeding device includes a pipe rack for receiving pipes, the pipe rack being configured to allow the pipes to move along their own weight direction; characterized in that it further includes: A feeding mechanism is used to store pipes, and the feeding mechanism can adjust the feeding gap according to the diameter of the current batch of pipes to achieve feeding one pipe at a time. An adjustment mechanism, installed on the pipe rack, is used to ensure that the pipes are arranged tightly together on the pipe rack without stacking. The feeding mechanism includes: A tilting component is rotatably mounted on the pipe rack, and the tilting component has the following features: A pointed end for insertion between two adjacent pipes; An arc-shaped portion is disposed on the side of the flipping component near the feeding mechanism, the arc-shaped portion facing the pipe on the pipe rack located upstream of the flipping component, and the arc-shaped portion is connected to the tip portion; A stop block is movably mounted on the pipe rack and located at one end of the pipe rack near the loading station to prevent the pipe from continuing to advance along the pipe rack. The stop block is configured to adjust its position according to the pipe diameter so that the gap between the two pipes closest to the flipper is aligned with the tip. The flipping component has a first rotational position and a second rotational position around its rotational axis; In the first rotation position, the tip is inserted into the gap between the two tubes closest to the flipper, and the tip abuts against the lower surface of the tube closest to the flipper. In the second rotation position, the tip lifts the pipe closest to the flipper and detaches it from the pipe rack, while the arc-shaped part abuts against the outer wall of the pipe located upstream and adjacent to the flipper.

[0007] By adopting the above technical solution, the feeding mechanism can adjust the feeding gap according to the diameter of the current batch of pipes, so as to feed the pipes one by one and avoid feeding multiple pipes at one time. After the pipe rack receives the pipes, the adjustment mechanism makes the pipes lined up tightly on the pipe rack in sequence without stacking them up and down, thus ensuring the stability and orderliness of the pipe arrangement. In the feeding mechanism, the tip of the flipping part is used to insert between two adjacent pipes. The stop block can be adjusted according to the pipe diameter so that the gap between the two pipes closest to the flipping part is aligned with the tip, ensuring that the tip can be stably inserted into the gap. During the automated feeding process of pipes, when the feeding tip rotates to the first rotation position, the tip inserts into the gap and abuts against the lower surface of the foremost pipe. When it continues to rotate to the second rotation position, the tip lifts the foremost pipe and removes it from the pipe rack, realizing single-pipe feeding. At the same time, the arc-shaped part abuts against the outer wall of the subsequent pipe, temporarily preventing the subsequent pipe from moving downstream and avoiding the phenomenon of continuous material during the feeding process. After the flipper rotates, the curved surface is no longer restricted to the subsequent pipes. The subsequent pipes continue to move down to the loading position under the action of gravity, waiting for the next loading action. It can adapt to different batches and different diameters of pipes without the need for manual adjustment or replacement of parts, and achieves stable and reliable one-by-one loading.

[0008] Preferably, the feeding mechanism includes a storage bin for storing pipes, a transfer bin disposed at the outlet of the storage bin, and a transfer component rotatably disposed within the transfer bin. The transfer component is an inflatable air bladder, and a gap is formed between the outer surface of the transfer component and the inner wall of the transfer bin to allow a single pipe to pass through.

[0009] By adopting the above technical solution, the storage bin in the feeding mechanism is used to store pipes, and the transfer bin is set at the outlet of the storage bin. After the pipes enter the transfer bin from the storage bin, they are transported by an inflatable material transfer component that is rotatably set in the transfer bin. A gap is formed between the outer surface of the material transfer component and the inner wall of the transfer bin to allow a single pipe to pass through. When the material transfer component rotates, the pipes pass through the gap in sequence, thereby realizing the feeding of pipes one by one. Because the material transfer component is inflatable, the gap between its outer surface and the inner wall of the transfer hopper can be changed by adjusting the inflation volume, thus adapting to pipes of different diameters without replacing any parts; it is simple and compact, and the material release is reliable, effectively avoiding the release of multiple pipes at once or the phenomenon of material jamming, providing a prerequisite guarantee for the orderly arrangement and stable feeding of subsequent pipes on the pipe rack.

[0010] Preferably, the outer surface of the material transfer component is provided with a uniformly distributed concave-convex structure, and the concave-convex structure of the outer surface of the material transfer component is configured to contact the pipe and drive the pipe into the gap between the outer surface of the material transfer component and the inner wall of the transfer hopper.

[0011] By adopting the above technical solution, the uniformly distributed concave-convex structure on the outer surface of the material transfer component contacts the surface of the pipe when the material transfer component rotates, increasing the friction between the material transfer component and the pipe. This actively guides the pipe into the gap between the outer surface of the material transfer component and the inner wall of the transfer bin, effectively avoiding the problems of the pipe getting stuck, slipping, or unable to enter the gap in the transfer bin, thus improving the reliability and continuity of the feeding mechanism. At the same time, the uniform distribution of the concave-convex structure ensures that the force exerted by the material transfer component on each pipe is consistent during rotation, further realizing stable feeding of each pipe one by one.

[0012] Preferably, the device further includes a controller connected to the material transfer element. The controller is configured to automatically adjust the air volume of the material transfer element according to the diameter of the current batch of pipes, so that the gap between the outer surface of the material transfer element and the inner wall of the transfer hopper is smaller than the diameter of the current batch of pipes. The material transfer element is made of an elastic material, and when the material transfer element rotates, it can undergo elastic deformation to allow the pipes to pass through the gap.

[0013] By adopting the above technical solution, the uniformly distributed concave-convex structure on the outer surface of the material transfer component comes into contact with the surface of the pipe when the material transfer component rotates, generating sufficient friction or pushing force. This actively guides the pipe into the gap between the outer surface of the material transfer component and the inner wall of the transfer bin, preventing the pipe from getting stuck or slipping in the transfer bin and improving the reliability and continuity of material feeding. At the same time, the uniform distribution of the concave-convex structure ensures that the force exerted by the material transfer component on each pipe remains consistent during rotation, further guaranteeing the stability of feeding pipe by pipe.

[0014] Preferably, the controller is also connected to the drive unit of the material transfer component, and the controller is configured to automatically adjust the rotation speed of the material transfer component according to the turning speed of the turning component, so as to control the rate at which the pipe is released onto the pipe rack.

[0015] By adopting the above technical solution, the controller automatically adjusts the rotation speed of the conveyor according to the turning speed of the turning component, so that the rate at which the unloading mechanism releases the pipes matches the feeding rate of the feeding mechanism. This avoids excessive accumulation of pipes on the pipe rack due to unloading too quickly, or idling and waiting due to unloading too slowly. As a result, the unloading and feeding work in tandem, improving the overall operating efficiency and automation of the device.

[0016] Preferably, the feeding mechanism includes a retractable baffle disposed in the transfer hopper. The baffle is located on one side of the material transfer component. The retraction amount of the baffle is adjusted by a controller according to the diameter of the pipe in the current batch. The gap between the baffle and the outer surface of the material transfer component is smaller than the diameter of the pipe in the current batch, so as to prevent the pipe from passing through this side of the material transfer component.

[0017] By adopting the above technical solution, the retractable baffle is set in the transfer bin and located on one side of the transfer component. The controller automatically adjusts the extension and retraction of the baffle according to the diameter of the current batch of pipes, so that the gap between the baffle and the outer surface of the transfer component is smaller than the diameter of the pipe, thereby effectively preventing the pipes from passing through this side of the transfer component and ensuring that all pipes are transmitted out sequentially only through the gap between the transfer component and the inner wall of the transfer bin. It effectively avoids the problem of material jamming or chaotic feeding caused by the pipes being diverted to both sides of the material conveying component in the transfer bin, ensuring the reliability of the feeding mechanism feeding one pipe at a time. At the same time, it can automatically adjust through the controller and adapt to the feeding needs of pipes of different diameters without manual intervention.

[0018] Preferably, a discharge hole is provided at the lower arc surface of the transfer bin, and a sliding block is slidably disposed in the discharge hole. The driving component of the sliding block is controlled by the controller, and the controller controls the position of the sliding block to adjust the size of the discharge hole.

[0019] By adopting the above technical solution, a discharge hole is opened at the lower arc surface of the transfer bin. The sliding block installed in the discharge hole is controlled by the controller to adjust the position of the discharge hole, thereby adjusting the size of the discharge hole. When the diameter of the pipe changes, the controller can automatically adjust the position of the sliding block to make the size of the discharge hole match the diameter of the current batch of pipes, ensuring that the pipes can smoothly pass through the discharge hole into the subsequent work station.

[0020] Preferably, the feeding mechanism further includes a material transfer bin, the inlet of which is aligned with the discharge hole, and the outlet of which is aligned with the pipe rack.

[0021] By adopting the above technical solution, the inlet of the hopper is aligned with the discharge hole, and the outlet is aligned with the pipe rack. After the pipe falls from the discharge hole into the transfer hopper, it is guided to the pipe rack. The transfer hopper plays a receiving and guiding role, enabling the pipe to smoothly and orderly transition from the feeding mechanism to the pipe rack. This avoids the pipe from deflecting, jumping or colliding with each other during the falling process, and ensures the consistency of the posture and the orderly arrangement of the pipe when it enters the pipe rack.

[0022] Preferably, the adjustment mechanism includes an adjustment plate that is vertically slidably disposed at the discharge port of the material transfer hopper. The tilt angle of the adjustment plate is the same as the tilt angle of the pipe placement part on the pipe rack. The controller adjusts the distance between the adjustment plate and the pipe rack according to the diameter of the current batch of pipes so that the distance allows only a single pipe to pass through.

[0023] By adopting the above technical solution, the adjusting plate is vertically slidably set at the discharge port of the material conveying bin, and its tilt angle is the same as the tilt angle of the pipe rack where the pipes are placed. The controller automatically adjusts the distance between the adjusting plate and the pipe rack according to the diameter of the current batch of pipes, so that this distance allows only a single pipe to pass through. It effectively prevents pipes from stacking up and down when entering the pipe rack, ensuring that the pipes are arranged tightly in sequence on the pipe rack, providing a reliable guarantee for the stable insertion of subsequent turning parts and the feeding of pipes one by one. At the same time, through automatic adjustment by the controller, it can adapt to pipes of different diameters without manual intervention, improving the automation level and adaptability of the device.

[0024] Preferably, the feeding mechanism includes a rotating shaft rotatably mounted on the pipe rack, a support plate mounted on the rotating shaft, and a driving assembly for driving the rotating shaft to rotate, wherein the stop block is mounted on the support plate.

[0025] By adopting the above technical solution, the rotating shaft is rotatably mounted on the pipe rack, the support plate is fixed on the rotating shaft, and the stop block is mounted on the support plate. When the drive component drives the rotating shaft to rotate, the support plate drives the stop block to swing around the axis of the rotating shaft, thereby realizing the adjustment of the stop block position. The position of the stop block can be precisely adjusted according to the pipe diameter so that the gap between the two pipes closest to the flipping part is aligned with the tip, ensuring that the tip of the flipping part can be stably inserted into the gap to complete the feeding action each time.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The feeding mechanism can adjust the feeding gap according to the diameter of the current batch of pipes to achieve feeding one pipe at a time, avoiding feeding multiple pipes at once. After the pipe rack receives the pipes, the adjustment mechanism makes the pipes lined up tightly on the pipe rack without stacking them up or down, ensuring the stability and orderliness of the pipe arrangement. In the feeding mechanism, the tip of the flipping part is used to insert between two adjacent pipes. The stop block can be adjusted according to the pipe diameter to align the gap between the two pipes closest to the flipping part with the tip, ensuring that the tip can be stably inserted into the gap. During the automated feeding process of pipes, when the feeding tip rotates to the first rotation position, the tip inserts into the gap and abuts against the lower surface of the foremost pipe. When it continues to rotate to the second rotation position, the tip lifts the foremost pipe and removes it from the pipe rack, realizing single-pipe feeding. At the same time, the arc-shaped part abuts against the outer wall of the subsequent pipe, temporarily preventing the subsequent pipe from moving downstream and avoiding the phenomenon of continuous material during the feeding process. After the flipper rotates, the curved surface is no longer restricted to the subsequent pipes. The subsequent pipes continue to move down to the loading position under the action of gravity, waiting for the next loading action. It can adapt to different batches and different diameters of pipes without manual adjustment or replacement of parts, and achieves stable and reliable one-by-one loading. 2. The storage bin in the feeding mechanism is used to store pipes. The transfer bin is set at the outlet of the storage bin. After the pipes enter the transfer bin from the storage bin, they are transported by an inflatable material transfer component that is rotated inside the transfer bin. A gap is formed between the outer surface of the material transfer component and the inner wall of the transfer bin to allow a single pipe to pass through. When the material transfer component rotates, the pipes pass through the gap one by one, thereby realizing the feeding of pipes one by one. Because the material transfer component is inflatable, the gap between its outer surface and the inner wall of the transfer hopper can be changed by adjusting the inflation amount, thus adapting to pipes of different diameters without replacing any parts; it is simple and compact, and the material release is reliable, which can effectively avoid releasing multiple pipes at once or jamming, providing a prerequisite guarantee for the orderly arrangement and stable feeding of subsequent pipes on the pipe rack. 3. The adjusting plate is vertically slidably set at the discharge port of the material conveying bin, and its tilt angle is the same as the tilt angle of the pipe rack where the pipes are placed. The controller automatically adjusts the distance between the adjusting plate and the pipe rack according to the diameter of the current batch of pipes, so that this distance allows only a single pipe to pass through. It effectively prevents pipes from stacking up and down when entering the pipe rack, ensuring that the pipes are arranged tightly in sequence on the pipe rack, providing a reliable guarantee for the stable insertion of subsequent turning parts and the feeding of pipes one by one. At the same time, through automatic adjustment by the controller, it can adapt to pipes of different diameters without manual intervention, improving the automation level and adaptability of the device.

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] This application discloses an automatic pipe fitting feeding device. (Refer to...) Figure 1 As shown, an automatic pipe feeding device includes a controller, a pipe rack 1, a feeding mechanism 2, an adjusting mechanism 3, and a feeding mechanism 4.

[0033] Reference Figure 1 As shown, the pipe rack 1 is used to support the pipe material and is configured to allow the pipe material to move on it along its own gravity direction. The pipe rack 1 is arranged at an inclination, with its high end close to the discharge end of the feeding mechanism 2 and its low end close to the feeding station. The pipe material rolls from the high end to the low end under the action of gravity.

[0034] Reference Figure 1 and Figure 2 As shown, the feeding mechanism 2 includes a storage bin 21, a transfer bin 22, a transfer component 23, a baffle 24, and a transfer bin 25. The storage bin 21 is located next to the pipe rack 1, and the length direction of the storage bin 21 is the same as the length direction of the pipe rack 1. The storage bin 21 is used to store pipes. The transfer bin 22 is located at the outlet of the storage bin 21, and the length direction of the transfer bin 22 is the same as the length direction of the pipe rack 1. A baffle 211 is slidably installed inside the discharge port of the storage silo 21. The baffle 211 is connected to a drive unit, and the controller is signal-connected to the drive unit. When it is necessary to release the pipe in the storage silo 21 into the transfer silo 22, the controller controls the baffle 211 to slide away from the discharge port of the storage silo 21, so that the pipe in the storage silo 21 falls into the transfer silo 22 through the discharge port. In addition, by adjusting the position of the baffle 211 inside the discharge port of the storage silo 21, the effective opening size of the discharge port of the storage silo 21 can be changed, thereby adjusting the release rate of the pipe entering the transfer silo 22.

[0035] Reference Figure 2 As shown, a discharge hole 221 is provided at the lower arc surface of the transfer bin 22. A sliding block 222 is slidably arranged in the discharge hole 221. The driving component of the sliding block 222 is controlled by the controller. The controller adjusts the position of the sliding block 222 to adjust the size of the discharge hole 221 so that the discharge hole 221 matches the diameter of the current batch of pipes, ensuring that the pipes can pass through smoothly.

[0036] Reference Figure 1 and Figure 2 As shown, the material transfer element 23 is rotatably disposed inside the transfer chamber 22. The material transfer element 23 is an inflatable air bag. A gap is formed between the outer surface of the material transfer element 23 and the inner wall of the transfer chamber 22 to allow a single pipe to pass through. When the material transfer element 23 rotates, the pipes pass through the gap one by one, thereby realizing the feeding of pipes one by one. By adjusting the inflation amount of the material transfer element 23, the size of the gap can be changed to accommodate pipes of different diameters. The outer surface of the material transfer component 23 is provided with a uniformly distributed concave and convex structure. When the concave and convex structure comes into contact with the pipe, it generates friction and can actively drive the pipe into the gap between the outer surface of the material transfer component 23 and the inner wall of the transfer bin 22, thus preventing the pipe from being stuck or slipping in the transfer bin 22. The controller is connected to the material transfer element 23 by signal and is configured to automatically adjust the air volume of the material transfer element 23 according to the diameter of the current batch of pipes, so that the gap between the outer surface of the material transfer element 23 and the inner wall of the transfer bin 22 is smaller than the diameter of the current batch of pipes. The material transfer component 23 is made of elastic material. When the material transfer component 23 rotates, it can undergo elastic deformation to allow the pipe to pass through the gap. That is, in the static state, the gap is smaller than the diameter of the pipe, and the pipe cannot pass through freely. During the rotation of the material transfer component 23, the pipe is squeezed into the gap under the action of the concave and convex structure, the material transfer component 23 undergoes elastic deformation, and the material transfer component 23 returns to its original shape after the pipe passes through.

[0037] Reference Figure 1 and Figure 2As shown, the baffle 24 is telescopically installed inside the transfer hopper 22. The baffle 24 is located on one side of the transfer component 23. The telescopic amount of the baffle 24 is adjusted by the controller according to the diameter of the current batch of pipes, so that the gap between the baffle 24 and the outer surface of the transfer component 23 is smaller than the diameter of the current batch of pipes, so as to prevent the pipes from passing through this side of the transfer component 23 and ensure that all pipes are sequentially transmitted only through the gap between the transfer component 23 and the inner wall of the transfer hopper 22.

[0038] Reference Figure 1 As shown, the material transfer bin 25 is located below the transfer bin 22. The inlet of the material transfer bin 25 is aligned with the discharge hole 221, and the outlet of the material transfer bin 25 is aligned with the pipe rack 1. After the pipe falls from the discharge hole 221 into the material transfer bin 25, it is guided by the material transfer bin 25 to the pipe rack 1 to achieve a smooth transition.

[0039] Reference Figure 1 and Figure 3 As shown, the feeding mechanism 4 is located at the lower end of the pipe rack 1 (the end closest to the feeding station), and includes a tilting component 41, a stop block 42, a rotating shaft 43, a support plate 44, a rotating column 45, a cylinder 46, and a drive assembly 47. The rotating shaft 43 is rotatably mounted on the pipe rack 1, and the length direction of the rotating shaft 43 is the same as the length direction of the pipe rack 1. The drive assembly 47 is used to drive the rotating shaft 43 to rotate. The controller regulates the drive assembly 47. The drive assembly 47 is existing technology and will not be described in detail in this embodiment. The material turning component 41, the stop block 42, and the support plate 44 are arranged in a one-to-one correspondence, and multiple of each are provided. In this embodiment, each of the three is preferably set to five. The support plate 44 is set on the rotating shaft 43 and the support plates 44 are evenly distributed at equal distances along the length direction of the rotating shaft 43. The stop block 42 is set on the support plate 44.

[0040] Reference Figure 1 and Figure 3 As shown, the rotating column 45 is rotatably mounted on the pipe rack 1. The rotating column 45 is close to the rotating shaft 43. The length direction of the rotating column 45 is the same as the length direction of the pipe rack 1. The material turning component 41 is mounted on the rotating column 45. The material turning component 41 is evenly distributed at equal distances along the length direction of the rotating column 45. The material turning component 41 is close to the stop block 42. The cylinder 46 is mounted on the pipe rack 1, and its piston rod is connected to one of the tipping parts 41. The controller controls the action of the cylinder 46, driving the tipping part 41 connected to it to rotate. Under the drive of the rotating column 45, all tipping parts 41 rotate synchronously. The flipping component 41 has a pointed part 411 and an arcuate part 412. The pointed part 411 is used to insert between two adjacent pipes. The arcuate part 412 is located on the side of the flipping component 41 near the feeding mechanism 2. The arcuate part 412 faces the pipe on the pipe rack 1 located upstream of the flipping component 41, and the arcuate part 412 is connected to the pointed part 411.

[0041] Reference Figure 1 and Figure 3 As shown, the stop block 42 is located at one end of the pipe rack 1 near the loading station. The stop block 42 is used to prevent the pipe from continuing to move along the pipe rack 1. The stop block 42 is configured to adjust its position according to the pipe diameter so that the gap between the two pipes closest to the flipper 41 is aligned with the tip 411. The flipping component 41 has a first rotation position and a second rotation position around its rotation axis; when the flipping component 41 is in the first rotation position, the tip 411 is inserted into the gap between the two tubes closest to the flipping component 41, and the tip 411 abuts against the lower surface of the tube closest to the flipping component 41. When the flipper 41 rotates to the second rotation position, the tip 411 lifts the pipe closest to the flipper 41 and removes it from the pipe rack 1, while the arc-shaped surface 412 abuts against the outer wall of the pipe located upstream of the flipper 41 and adjacent to it.

[0042] Reference Figure 1 As shown, the adjustment mechanism 3 includes an adjustment plate 31, which is vertically slidably disposed at the discharge port of the material transfer bin 25 and connected to a driving component (such as an electric push rod or screw mechanism). The length direction of the adjustment plate 31 is the same as the length direction of the pipe rack 1, and the tilt angle of the adjustment plate 31 is the same as the tilt angle of the part on the pipe rack 1 where the pipes are placed. The controller adjusts the distance between the adjustment plate 31 and the pipe rack 1 according to the diameter of the current batch of pipes, so that the distance allows only a single pipe to pass through, preventing the pipes from stacking up and down when entering the pipe rack 1.

[0043] The implementation principle of the automatic pipe fitting feeding device in this application embodiment is as follows: The feeding mechanism 2 adjusts the feeding gap according to the diameter of the current batch of pipes, and releases the pipes one by one to the high end of the pipe rack 1. Under the action of their own gravity, the pipes roll along the pipe rack 1 to the low end. The adjusting mechanism 3 makes the pipes lined up tightly on the pipe rack 1 without stacking. The pipe at the front end is blocked by the stop block 42 and stops at the waiting position. The stop block 42 adjusts its position according to the pipe diameter so that the gap between the two pipes closest to the flipper 41 is aligned with the tip 411 of the flipper 41. When feeding is required, the tilting component 41 is driven to rotate by the cylinder 46. The tilting component 41 rotates from the first rotation position to the second rotation position, and its tip 411 is inserted into the gap between two adjacent pipes and abuts against the lower surface of the foremost pipe. As the tilting component 41 continues to rotate, the tip 411 lifts the foremost pipe upward, causing it to detach from the pipe rack 1 and flip to the feeding station, completing the single-pipe feeding. At the same time, the arc-shaped surface 412 on the tilting component 41 abuts against the outer wall of the subsequent pipe, temporarily preventing the subsequent pipe from moving downstream and avoiding the phenomenon of continuous material during the tilting process. After the material-flipping component 41 completes the loading, it rotates in the opposite direction. The arc-shaped part 412 releases the restriction on the subsequent pipe. The subsequent pipe continues to move downstream under the action of gravity until it is blocked by the stop block 42, and enters the preparation state for the next loading. Throughout the entire operation, the controller automatically adjusts the air volume of the conveyor 23, the extension and retraction of the baffle 24, the position of the sliding block 222, the distance between the adjusting plate 31 and the pipe rack 1, and the position of the stop block 42 according to the diameter of the current batch of pipes. At the same time, it automatically adjusts the rotation speed of the conveyor 23 according to the turning speed of the turning component 41, so as to realize the automated and coordinated control of the entire process of feeding, arranging, and loading.

[0044] The above are all preferred embodiments 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.
