Description

Technical Field

[0001] This invention relates to the field of pipe feeding, and more particularly to a pipe feeding and laying device, a pipe feeding apparatus, and a pipe feeding method. Background Technology

[0002] Laser tube cutting machines are characterized by high precision, fast cutting speed, no limitation on cutting patterns, smooth cuts, and low processing costs. They have gradually replaced traditional tube cutting equipment. In the entire processing process, the feeding process is an important link. Quickly and accurately transporting the tube to the processing position can improve the efficiency of the entire processing process. Most tube feeding is done manually or semi-automatically, which are inefficient.

[0003] An existing technology discloses an automatic pipe feeding mechanism, including a feeding frame, a feeding device, a conveying device, and a pushing device. The feeding device, conveying device, and pushing device are all mounted on the feeding frame, with the pushing device and feeding device located on opposite sides of the conveying device. The feeding frame has an inclined surface, with the pushing device located at the bottom end of the inclined surface. The feeding device includes a first motor, a feeding belt, a first transmission rod, and a limiting rod. Both ends of the first transmission rod are mounted on the feeding frame, and the first transmission rod is connected to the output shaft of the first motor. The first transmission rod has multiple take-up wheels. The limiting rod and the feeding belt correspond to multiple take-up wheels. One end of the feeding belt is fixed to the limiting rod, and the other end is fixed to the take-up wheel. The limiting rod is located on the front side of the feeding frame. Therefore, the first motor drives the winding wheel to rotate, thereby gradually pulling the feeding belt upward, allowing the pipes on the feeding belt to move upward to the conveying device. The end of the inclined surface of the feeding frame is provided with an upward folding edge. The pushing device includes a cylinder and a push plate. The cylinder is inclined at the bottom of the inclined surface, and the push plate is connected to the piston rod of the cylinder. When the cylinder pushes the push plate upward, the push plate pushes upward, pushing a pipe above the push plate upward, realizing single-pipe feeding. This technical solution, through the feeding device, can easily transport piles of pipes to the conveying device, and allows the pipes on the inclined surface to be pushed out one by one, eliminating the need for manual feeding, saving labor, and improving feeding efficiency.

[0004] However, when feeding some slender tubes, due to the large deflection of the slender tubes, there is a situation where the material gets tangled and twisted. This causes multiple slender tubes to become tangled together and fall onto the push plate. When the push plate moves up, it often moves multiple tubes up, or it cannot move the tubes up at all, making it impossible to ensure feeding one tube at a time. Manual assistance is required, which affects production efficiency. Summary of the Invention

[0005] To address the technical problem that existing pipe feeding devices cannot guarantee the feeding of slender pipes one by one, this invention provides a pipe feeding and laying device, a pipe feeding device, and a pipe feeding method, which can avoid pipe entanglement and achieve feeding one pipe at a time.

[0006] In a first aspect, the present invention provides a pipe feeding and laying device to solve the above-mentioned technical problems, including a first feeding rack, and further comprising:

[0007] The second feeding rack is located in front of the first feeding rack along the conveying direction. The feeding surface height of the second feeding rack is lower than that of the first feeding rack. The second feeding rack and the first feeding rack are connected by a sliding guide plate.

[0008] The top material assembly is disposed at the feeding end of the first feeding rack. The top material assembly includes a top material plate and a top material cylinder connected to each other. One of the top corners of the top material plate is set upward. The top material cylinder can drive the top material plate to reciprocate in the vertical direction. The top material plate can extend and retract from the feeding surface of the first feeding rack.

[0009] This invention, through two feeding racks of different heights and a top feeding assembly, enables multiple slender tubes to slide and disperse during feeding and conveying, achieving a flat laying effect, avoiding entanglement and twisting, and facilitating feeding one tube at a time.

[0010] Furthermore, both the first and second feeding racks include support frames, and the two support frames are connected as an integrated structure. Each support frame has two sets of conveyor chains arranged opposite each other, and the two sets of conveyor chains are connected to the same drive motor. Two sets of top-feeding components are provided, and the two sets of top-feeding components are arranged opposite each other on the support frames.

[0011] Furthermore, the top material assembly also includes a support, which is mounted on the support frame of the first feeding frame. The top material cylinder is mounted on the support, and a synchronous rack is vertically mounted on the support. The synchronous rack meshes with a synchronous gear, and the synchronous gears of the two sets of top material assemblies are mounted on the same synchronous shaft. The synchronous shaft is tractably mounted on the support frame.

[0012] By setting up a synchronous rack, gear, and synchronous shaft, this invention can ensure that the two top material cylinders move synchronously and reach the same height, and ensure that the two top material plates act on the pipe at the same time.

[0013] Furthermore, it also includes a first pipe sensor. The feeding end of the first feeding rack is provided with a mounting hole. The first pipe sensor is connected to the first feeding rack through the mounting hole. The mounting hole is a straight groove hole, and the length direction of the straight groove hole is parallel to the conveying direction.

[0014] This invention adjusts the position of the first sensor to allow for adjustment of the amount of material fed to the second feeding rack at one time, based on the processing content and pipe size, ensuring that it matches the processing cycle of the cutting machine and making it flexible in use.

[0015] Furthermore, the feeding end of the support frame of the second feeding rack is provided with a mounting base, on which a second pipe sensor is provided. The mounting base is also rotatably provided with a trigger plate, which can be driven in a vertical plane. A sensing plate and a counterweight are connected in sequence to the inward side of the trigger plate, and the second pipe sensor can sense the sensing plate.

[0016] This invention uses a trigger plate and a sensing plate to enable the second pipe sensor to indirectly sense the pipe's location, thus avoiding the situation where the second pipe sensor has a small sensing range and cannot sense thinner pipes.

[0017] Secondly, the present invention also provides a pipe feeding device, comprising at least two sets of the above-mentioned pipe feeding and laying devices, and further comprising a feeding assembly, the feeding assembly comprising:

[0018] The base frame is located at the feeding end of the second feeding frame. A sliding plate is inclinedly provided on the feeding side of the base frame. A limiting part is provided at the end of the sliding plate. A support guide rail is inclined downward on the feeding side of the base frame.

[0019] At least two fixing plates, the loading surface of the fixing plates is a stepped surface, and the fixing plates are arranged on the loading side of the base frame;

[0020] At least two movable plates, the number of which is the same as the number of fixed plates, the loading surface of the movable plates is a stepped surface, the movable plates are connected to a drive assembly, the movable plates are reciprocally mounted on the support guide rail, the lower end of the movable plates can extend into the lower side of the feeding end of the second loading rack, the movable plates are arranged parallel to the fixed plates, and the movable plates can push the pipe to move along the fixed plates;

[0021] The third pipe sensor is mounted on the base frame and located at the stepped material position on the top of the fixed plate.

[0022] This invention enables sequential feeding of pipes by setting a movable plate and a fixed plate with stepped surfaces, further avoiding pipe entanglement and twisting during feeding, and ensuring sequential feeding of pipes.

[0023] Furthermore, the multiple moving plates are connected by a sliding beam, the sliding beam is connected to the support guide rail, a transmission support is provided on the sliding beam, the driving assembly includes a feeding motor, the feeding motor drives a transmission shaft, the transmission shaft is rotatably mounted on the base frame, an eccentric wheel is provided on the transmission shaft, and the eccentric wheel abuts against the transmission support.

[0024] This invention enables multiple moving plates to move simultaneously through the cooperation of a feeding motor and multiple eccentric wheels, thereby improving the reliability of feeding and preventing profiles from slipping off.

[0025] Furthermore, the fixing plate is connected to an adjustment assembly, and the fixing plate is movably mounted on the base frame. The direction of movement of the fixing plate is perpendicular to the tilt direction of the support guide rail.

[0026] This invention makes the position of the fixed plate adjustable, allowing for adjustment of its relative position to the moving plate. This ensures that regardless of the profile's thickness, the moving plate has sufficient contact area with the pipe, preventing the pipe from rotating when the moving plate pushes it, thus improving feeding efficiency.

[0027] Furthermore, it also includes a centering component located at the end of the sliding plate. The centering component includes a lifting platform connected to a lifting cylinder. A finger cylinder and a rope sensor are provided on the lifting platform. Two grippers of the finger cylinder are respectively connected to gripping rollers. One gripper of the finger cylinder is connected to the body of the rope sensor, and the other gripper is connected to the rope of the rope sensor.

[0028] The present invention, through the centering component, can adjust the position of the profile on the lifting platform, so as to facilitate the accurate clamping and transfer of the cutting machine. On the other hand, the pull rope sensor can determine the posture of the rectangular tube, so as to facilitate the cutting machine to adjust the posture of the clamping device.

[0029] Thirdly, the present invention also provides a pipe feeding method, using the above-mentioned pipe feeding device, comprising the following steps:

[0030] S01: Place multiple pipes on multiple first loading racks;

[0031] S02: The first feeding rack transports the pipe. When the first pipe is moved into place, the first feeding rack stops conveying, the top plate rises, and the pipe located in front of the top plate on the first feeding rack slides down to the second feeding rack.

[0032] S03: The second feeding rack transports the pipe to the feeding end. At this time, the first feeding rack stops transporting.

[0033] S04: The moving plate reciprocates to transfer the pipes one by one from the second feeding rack to the fixed plate, and pushes the pipes along the fixed plate to the stepped material position at the top of the fixed plate;

[0034] S05: When the pipe reaches the stepped material position at the top of the fixed plate, if no feeding is required, the moving plate and the second feeding rack stop moving. If feeding is required, the moving plate pushes the pipe from the stepped material position at the top of the fixed plate to the end of the sliding plate. Then the lifting platform rises to the set height, and the clamping rollers hold the profile, waiting for transfer. After the profile slides to the end of the sliding plate, the moving plate continues to transport the pipe to the stepped material position at the top of the fixed plate to wait for feeding. The second feeding rack continues to transport the pipe to the feeding end. When there is no pipe on the second feeding rack, repeat S02 to S03.

[0035] This invention ensures that there are always pipes at the top of the fixed plate step, which can shorten the waiting time when materials need to be loaded and improve production efficiency.

[0036] As can be seen from the above technical solutions, the present invention has the following advantages:

[0037] This invention provides a pipe feeding and spreading device, a pipe feeding apparatus, and a pipe feeding method. By using two feeding racks at different heights and a top-feeding assembly, multiple slender pipes can be dispersed and spread out during feeding, achieving a flat spreading effect and avoiding entanglement and twisting, facilitating feeding one pipe at a time. By setting a synchronous rack, gears, and synchronous shaft, the two top-feeding cylinders can move synchronously and reach the same height, ensuring that both top-feeding plates simultaneously move on the pipes. By making the position of the first sensor adjustable, the amount of material fed to the second feeding rack at one time can be adjusted according to the processing content and pipe size, ensuring matching with the processing rhythm of the cutting machine and providing flexibility. The trigger plate and sensing plate enable the second pipe sensor to indirectly sense the pipe's arrival, avoiding the situation where the second pipe sensor has a small sensing range and cannot detect thinner pipes. The device also features a stepped surface. The system features a moving plate and a fixed plate, enabling sequential feeding of individual tubes and further preventing entanglement and twisting during feeding, ensuring consistent feeding. A feeding motor and multiple eccentric wheels allow for simultaneous movement of multiple moving plates, improving feeding reliability and preventing profile slippage. Adjustable fixed plate positions allow for adjustment of their relative position to the moving plate, ensuring sufficient contact area between the moving plate and the tube regardless of its thickness, preventing tube rotation during pushing and improving feeding efficiency. A centering component adjusts the profile's position on the lifting platform for accurate clamping and transfer by the cutting machine. A pull rope sensor determines the rectangular tube's posture, allowing the cutting machine to adjust the clamping device's posture. Ensuring a constant presence of tubes at the top step of the fixed plate shortens waiting time during feeding, improving production efficiency. Attached Figure Description

[0050] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0051] Slender pipes have low deflection and multiple pipes may become entangled, making it impossible to feed the pipes one by one. This requires manual assistance and cannot achieve fully automated feeding. To solve this technical problem, in at least one of the following embodiments, the inventors add a pipe-laying device before feeding. By adopting the technical concept of allowing the pipes to slide under their own weight, the entangled multiple pipes can be dispersed and laid flat, ensuring that the slender pipes are fed one by one. Specific Implementation Method 1

[0053] like Figures 1 to 3As shown in the figure, this specific embodiment provides a pipe feeding and laying device, including a first feeding rack 101, a second feeding rack 102, and a top feeding assembly. Along the conveying direction, the second feeding rack 102 is located in front of the first feeding rack 101, and the feeding surface height of the second feeding rack 102 is lower than the feeding surface height of the first feeding rack 101. The second feeding rack 102 and the first feeding rack 101 are connected by a sliding guide plate 104. The top feeding assembly is disposed at the feeding end of the first feeding rack 101. The top feeding assembly includes a top feeding plate 105 and a top feeding cylinder 107 connected to each other. One apex of the top feeding plate 105 is arranged facing upwards. The top feeding cylinder 107 can drive the top feeding plate 105 to reciprocate in the vertical direction. The top feeding plate 105 can extend and retract from the feeding surface of the first feeding rack 101.

[0054] This specific embodiment uses two feeding racks of different heights and a top feeding assembly. The top feeding assembly can lift the pipe and slide it down its own inclined surface and the sliding guide plate 104 onto the second feeding rack 102, so as to realize the sliding and dispersion of multiple slender pipes, achieve a flat laying effect, avoid entanglement and twisting, and facilitate feeding one pipe at a time.

[0055] like Figure 3 As shown, in this specific embodiment, in order to ensure a better material distribution effect, the top plate 105 adopts a triangular structure, and the upward-facing apex angle of the top plate 105 is an obtuse angle, which is 105° in this specific embodiment. The inclined surface of the top plate 105 extending towards the sliding guide plate 104 is parallel to the sliding guide plate 104.

[0056] like Figures 1 to 2 As shown, in this specific embodiment, both the first feeding rack 101 and the second feeding rack 102 include support frames, and the two support frames are connected as an integrated structure. Each support frame has two sets of conveyor chains 103 arranged opposite to each other. The two sets of conveyor chains 103 are connected to the same drive motor. Specifically, the conveyor chain 103 includes a chain, a drive sprocket, and a driven sprocket. The drive motor drives the drive shaft through a transmission belt. The drive shaft is rotatably mounted on the support frame. The drive shaft is equipped with a drive sprocket, and the driven sprocket is rotatably mounted on the support frame. Preferably, in order to achieve uniform separation of multiple pipes, two sets of top-feeding components are provided, and the two sets of top-feeding components are arranged opposite to each other on the support frame. It is understood that in other embodiments, the number of conveyor chains 103 can be adjusted as needed, and it is feasible to provide one or three.

[0057] like Figures 2 to 3As shown, since the two sets of top-feeding components are respectively equipped with top-feeding cylinders 107, in order to ensure that the two top-feeding cylinders 107 rise and fall synchronously, and thus ensure that multiple pipes can be neatly divided into two batches, and to avoid the pipes from tilting and sliding down and causing entanglement again, in this specific embodiment, the top-feeding component also includes a support 106. The support 106 is set on the support frame of the first loading rack 101, and the top-feeding cylinders 107 are set on the support 106. A synchronous rack 108 is vertically set on the support 106. The synchronous rack 108 meshes with a synchronous gear 110. The synchronous gears 110 of the two sets of top-feeding components are set on the same synchronous shaft 109. The synchronous shaft 109 is tractably set on the support frame. The extension and retraction of the two cylinders are balanced by the action of the synchronous rack 108 and the synchronous shaft 109, ensuring that the movement of the top plate 105 is consistent, and the multiple pipes can be neatly divided into two rows of pipes in front of the top plate 105 and behind the top plate 105.

[0058] To achieve automatic lifting and lowering of the top plate 105, this specific embodiment also includes a first pipe sensor 111. The first pipe sensor 111 is installed at the feeding end of the support frame of the first loading rack 101. The first pipe sensor 111 adopts a photoelectric switch. Since the size and processing content of different pipes are different, in order to make the feeding rhythm of the top plate 105 suitable for the subsequent processing rhythm, it is necessary to adjust the number of pipes conveyed by the top plate 105 in one slide according to the requirements. For this reason, a device is installed at the feeding end of the support frame. The mounting hole contains a bolt, and the first pipe sensor 111 is connected to the first feeding rack 101 through the mounting hole. The mounting hole is a straight groove hole, and the length direction of the straight groove hole is parallel to the conveying direction. With this setting, the installation position of the first pipe sensor 111 can be adjusted, thereby adjusting the number of pipes that slide down to the second feeding rack 102 after the top plate 105 is raised. When more pipes need to slide down, the installation position of the first pipe sensor 111 is adjusted backward along the conveying direction.

[0059] like Figure 4As shown, due to the limited capacity of the second feeding rack 102, the first feeding rack 101 should stop conveying when there is material at the feeding end of the second feeding rack 102 to avoid excessive pipes on the second feeding rack 102. Therefore, a second pipe sensor 112 is installed at the feeding end of the second feeding rack 102 to determine whether there are pipes at the feeding end. The second pipe sensor 112 is a proximity switch. Because pipes vary in thickness, adjacent pipes may have gaps due to slippage during conveying, and the sensing range of the proximity switch is small. To ensure effective sensing of pipes, a mounting base is provided at the feeding end of the support frame of the second feeding rack 102, and the second pipe sensor 112 is installed on the mounting base. The mounting base is also rotatably equipped with a trigger plate 113, which can be driven in a vertical plane. The trigger plate 113 is connected inward (near the support frame) to a sensing plate 115 and a counterweight 114. The second pipe sensor can sense the sensing plate 115. When no pipe reaches the feeding end, the trigger plate 113 is tilted up by the counterweight 114 and the sensing plate 115 is moved outside the sensing area of ​​the second pipe sensor 112. When the pipe reaches the feeding end, the trigger plate 113 is pressed down by the pipe, and the sensing plate 115 enters the sensing area. The second pipe sensor 112 determines that there is a pipe at the feeding end. At this time, the electrical control system controls the second feeding rack 112 to stop conveying.

[0060] To avoid scratching the profile, in this specific embodiment, nylon strips are provided on the two inclined sides of the top plate 105 and the sliding guide plate 104, and rubber blocks are provided on the chain links.

[0061] The working process of this device is as follows:

[0062] Multiple slender tubes (with some tangled material) are placed at the feeding end of the first feeding rack 101. The first feeding rack 101 conveys the tubes to the feeding end. When the first tube moves to the set position and is sensed by the first tube sensor 111, the first feeding rack 101 stops conveying, and the top plate 105 rises, dividing the tubes on the first feeding rack 101 into two parts. The multiple tubes in front of the top plate 105 slide down the inclined surface of the top plate 105 via the sliding guide plate 104 to the second feeding rack 102. The sliding guide plate 104 provides a longer sliding distance, so the multiple slender tubes are no longer tangled and fall flat on the second feeding rack 102. The second feeding rack 102 conveys the tubes to its own feeding end until the second tube sensor 112 senses that the tubes are in place. The second feeding rack 102 then stops conveying and waits for the next feeding. Specific Implementation Method Two

[0064] like Figures 5 to 8As shown, this specific embodiment provides a pipe feeding device, including at least two sets of pipe feeding and laying devices 1 of Specific Embodiment 1, and also includes a feeding assembly. The feeding assembly includes a base frame 2, a fixed plate 6, and a movable plate 5, wherein the number of fixed plates 6 and movable plates 5 are the same and they exist in pairs; the base frame 2 is located at the feeding end of the second feeding rack 102, and a sliding plate 7 is inclinedly arranged on the feeding side of the base frame 2. A limiting part 701 is provided at the end of the sliding plate 7 to prevent the pipe from sliding out of the sliding plate 7. A support guide rail 201 is inclined downward on the feeding side of the base frame 2, and the lower end of the support guide rail 201 is close to the second feeding rack 102; at least two fixed plates 6 are provided, the feeding surface of the fixed plate 6 is a stepped surface, and the fixed plate 6 is arranged on the feeding side of the base frame 2; the movable plate 5 is located at the feeding side of the base frame 2; the fixed plate 6 is located at the feeding end of the second feeding rack 102; the sliding plate 6 is located at the feeding end of the second feeding rack 102; the fixed ... The number of plates 5 and fixed plates 6 is the same. The feeding surface of the moving plate 5 is a stepped surface. The moving plate 5 is connected to a driving assembly. The moving plate 5 is reciprocally mounted on the support guide rail 201. The lower end of the moving plate 5 can extend into the lower side of the feeding end of the second feeding rack 102. The moving plate 5 is arranged parallel to the fixed plate 6. The moving plate 5 can push the pipe to move along the fixed plate 6. A third pipe sensor 11 is also provided. The third pipe sensor 11 is set on the base frame 2 and located at the stepped material position at the top of the fixed plate 6. In this specific embodiment, the third pipe sensor 11 is a photoelectric switch and is set at an angle. Its light emission direction is perpendicular to the support guide rail 201, which can accurately sense whether there is material on the first step at the top of the fixed plate 6.

[0065] This specific embodiment, by setting a movable plate 5 with a stepped surface and a fixed plate 6, can realize feeding one pipe at a time. Compared with the prior art of using a tape to feed inclined material, it can further avoid the situation of pipe entanglement and twisting during feeding, and ensure feeding one pipe at a time.

[0066] like Figure 7 and Figure 8As shown, to achieve the reciprocating movement of the moving plate 5 and the synchronous movement of multiple moving plates 5, in this specific embodiment, multiple moving plates 5 are connected by a sliding beam 12. The sliding beam 12 is connected to the support guide rail 201. A transmission support 13 is provided on the sliding beam 12, and multiple transmission supports 13 are provided. The driving assembly includes a feeding motor 16, which drives a transmission shaft 15 through a transmission belt. The transmission shaft 15 is rotatably mounted on the base frame 2 through bearings. Multiple eccentric wheels 14 are provided on the transmission shaft 15, and the number of eccentric wheels 14 is the same as the number of transmission supports 13. The transmission shaft 15 can drive the eccentric wheels 14 to rotate, and the eccentric wheels 14 abut against the corresponding transmission supports 13. When the feeding motor 16 drives the eccentric wheels 14 to rotate, the transmission shaft 15 can drive the eccentric wheels 14 to rotate. 4. When the eccentric wheel 14 rotates, it can push the slide beam 12 to move upward along the support rail 201 through the transmission support 13, thereby causing the moving plate 5 to move obliquely upward relative to the fixed plate 6. Through its own stepped surface, it pushes the pipe to move to the next step. When the protrusion of the eccentric wheel 14 rotates continuously until it is at the opposite end of the transmission support 13, the slide beam 12 slides obliquely downward along the support rail 201 under its own weight and the gravity of the moving plate 5. When the protrusion of the eccentric wheel 14 rotates continuously from the opposite end of the transmission support 13 until it abuts against the transmission support 13, the slide beam 12 slides obliquely upward along the support rail 201. As the eccentric wheel 14 rotates continuously, the slide beam 12 forms a reciprocating up-and-down movement along the support rail 201, continuously pushing the pipe to move upward along the steps of the fixed plate 6.

[0067] like Figure 8 and Figure 7 As shown, since the pipes include round, square, and rectangular pipes, and different pipes have different sizes, to prevent the moving plate 5 from slipping when pushing the pipe, the moving plate 5 should have sufficient contact area with the pipe. Therefore, to improve the flexibility of use and ensure that different pipes can be effectively pushed and fed, in this specific embodiment, the fixed plate 6 is connected to an adjustment component 8. The fixed plate 6 is movably mounted on the base frame 2, and the moving direction of the fixed plate 6 is perpendicular to the tilt direction of the support guide rail 201. The adjustment component 8 can adjust the relative distance between the moving plate 5 and the fixed plate 6 in the tilt direction perpendicular to the support guide rail 201, so that the feeding of pipes of various sizes can be guaranteed. The movable plate 5 has sufficient contact area to prevent slippage; furthermore, the adjustment assembly 8 includes a rotating shaft 804, which is rotatably mounted on the upper part of the base frame 2. The rotating shaft 804 is equipped with multiple adjusting gears 801, which can mesh with the adjusting racks 802 on the corresponding fixed plates 6. The fixed plates 6 can move along the slide rails on the base frame 2. One end of the rotating shaft 804 is also connected to a reducer 803. The reduction input shaft is connected to a handle. By manually cranking the reducer 803, multiple fixed plates 6 can be moved synchronously. The reducer 803 is a worm gear reducer 803 with a self-locking function to prevent the fixed plates 6 from moving in the opposite direction and causing the reducer 803 to rotate.

[0068] like Figure 9 and Figure 10 As shown, to achieve fully automated feeding, the falling profile needs to be positioned at the clamping position of the cutting machine's clamping assembly. Therefore, this specific embodiment also includes a centering assembly 3, located at the end of the sliding plate 7. The centering assembly 3 includes a lifting platform 301, on which a support roller 302 is horizontally arranged. The lifting platform 301 is connected to a lifting cylinder 305. A finger cylinder 306 is also provided on the lifting platform 301, with two grippers of the finger cylinder 306 respectively connected to clamping rollers 303. The movement of the lifting platform 301 and the movement of the clamping rollers 303... The clamping action allows for accurate positioning of the profile. Since the falling posture of the rectangular tube is uncertain, it is necessary to judge the feeding posture of the rectangular tube in order to further realize automatic feeding. One gripper of the finger cylinder 306 is connected to the body of the pull rope sensor, and the other gripper is connected to the pull rope of the pull rope sensor 304. When the rectangular tube is in a vertical or horizontal state, the distance the pull rope is pulled out is different. Through the signal feedback of the pull rope sensor 304, the control system can know the feeding posture of the rectangular tube, thereby adjusting the clamping posture of the cutting machine clamping assembly to achieve fully automatic feeding.

[0069] In this specific embodiment, in order to limit the pipe, a limiting plate 4 is provided at the end of the pipe feeding and laying device along the length of the pipe.

[0070] In this specific embodiment, there are 8 moving plates 5 and 8 fixed plates 6, 3 pipe feeding and laying devices 1, and 3 sets of conveyor chains 103 are provided near the limiting plate 4.

[0071] To prevent scratches on the profiles, nylon strips are installed on the drop plate 7. Specific Implementation Method 3

[0073] This specific embodiment provides a pipe feeding method, which uses the pipe feeding device of Specific Embodiment Two, and includes the following steps:

[0074] S01: Place multiple pipes on multiple first loading racks 101;

[0075] S02: The first feeding rack 101 transports the pipe. When the first pipe is moved into place, the first feeding rack stops transporting, the top plate 105 is raised, and the pipe located in front of the top plate 105 on the first feeding rack 101 slides down to the second feeding rack 102.

[0076] S03: The second feeding rack 102 transports the pipe to the feeding end. At this time, the first feeding rack 101 stops transporting.

[0077] S04: The moving plate 5 transfers the pipes one by one from the second feeding rack 102 to the fixed plate 6 by reciprocating movement, and pushes the pipes along the fixed plate 6 to the top of the fixed plate 6;

[0078] S05: When the pipe reaches the step position at the top of the fixed plate 6, if no feeding is required, the moving plate 5 and the second feeding rack 102 stop moving. If feeding is required, the moving plate 5 moves upward to push the pipe from the top of the fixed plate 6 to the end of the sliding plate 7. Then the lifting platform 301 rises to the set height, and the clamping roller 303 clamps the profile and waits for transfer. After the profile slides to the end of the sliding plate 7, the moving plate 5 continues to transport the pipe to the step position at the top of the fixed plate 6 to wait for feeding. The second feeding rack 102 continues to transport the pipe to the feeding end. When there is no pipe on the second feeding rack 102, repeat S02 to S03.

[0079] In S05 of this specific embodiment, when the third pipe sensor 11 detects material at the top and the control system simultaneously sends a signal indicating that material needs to be fed, the feeding motor 16 operates, driving the moving plate 5 upward and pushing the pipe from the top of the fixed plate 6 through the sliding plate 7 to the limiting part 701; when the third pipe sensor 11 detects material at the top but the control system does not send a feeding signal, the moving plate 5 and the second feeding rack 102 both stop operating and wait for feeding; when the third pipe sensor 11 does not detect material at the top, the moving plate 5 moves back and forth, pushing the pipe towards the stepped material position at the top of the fixed plate 6 until the third pipe sensor 11 detects material at the top; this specific embodiment, by ensuring that there is always pipe at the stepped material position at the top of the fixed plate 6, can shorten the waiting time when feeding is needed, which is beneficial to improving production efficiency.

[0080] To avoid placing too many pipes on the second feeding rack 102, in this specific embodiment, when there are no pipes on the second feeding rack 102, that is, when the second pipe sensor 112 does not detect any pipes within a set time after the second feeding rack 102 has started feeding pipes, the first feeding rack 101 starts feeding pipes, and after the pipes reach the set position, the first feeding rack 101 stops feeding, and the top plate 105 rises to achieve material distribution, and the second feeding rack 102 feeds the pipes forward.

[0081] As can be seen from the above specific embodiments, the present invention has the following beneficial effects:

[0082] 1. By using two feeding racks of different heights and a top feeding assembly, multiple slender pipes can be slid and dispersed during feeding and conveying, achieving a flat laying effect and avoiding entanglement and twisting, making it easier to feed one pipe at a time.

[0083] 2. By setting the synchronous rack 108, gear and synchronous shaft 109, it can be ensured that the two top material cylinders 107 move synchronously and reach the same height, and that the two top material plates 105 act on the pipe at the same time.

[0084] 3. By setting the position of the first sensor to be adjustable, the amount of material fed to the second feeding rack 102 at one time can be adjusted according to the processing content and pipe size, ensuring that it matches the processing cycle of the cutting machine and is flexible in use;

[0085] 4. By using the trigger plate 113 and the sensing plate 115 to indirectly sense the pipe's position, the second pipe sensor can avoid the situation where the second pipe sensor has a small sensing range and cannot sense thinner pipes.

[0086] 5. By setting a moving plate 5 with a stepped surface and a fixed plate 6, it is possible to feed the pipes one by one, further avoiding the situation of pipes getting tangled and twisted during feeding, and ensuring that the pipes are fed one by one.

[0087] 6. By cooperating with a feeding motor 16 and multiple eccentric wheels 14, multiple moving plates 5 can move simultaneously, improving the reliability of feeding and preventing profiles from slipping off;

[0088] 7. By making the position of the fixed plate 6 adjustable, the relative position with the moving plate 5 can be adjusted to ensure that the moving plate 5 has sufficient contact area with the pipe regardless of the thickness of the profile, thus preventing the pipe from rotating when the moving plate 5 pushes the pipe and improving the feeding efficiency.

[0089] 8. The centering component 3 can adjust the position of the profile on the lifting platform 301 to facilitate accurate clamping and transfer by the cutting machine. On the other hand, the pull rope sensor 304 can determine the posture of the rectangular tube to facilitate the cutting machine to adjust the posture of the clamping device.

[0090] 9. By ensuring that there is always a pipe on the top of the fixed plate 6, the waiting time when material needs to be loaded can be shortened, which is conducive to improving production efficiency.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
