[0004] However, when facing the loading of some slender pipes, due to the large deflection of the slender pipes, there is a situation of entanglement and twisting, which causes multiple slender pipes to be entangled with each other and fall on the push plate. When the push plate moves up, it often drives multiple pipes up, or fails to drive the pipes up, and it is impossible to ensure that the pipes are loaded one by one. Manual assistance is required, which affects production efficiency. Summary of the invention

[0005] In order to solve the technical problem that the pipe feeding device in the above-mentioned prior art cannot ensure the feeding of slender pipes one by one, the present invention provides a pipe feeding and laying device, a pipe feeding device and a pipe feeding method, which can avoid the entanglement of pipes and realize one-by-one feeding.

[0014] The present invention enables the second pipe sensor to indirectly sense the pipe in place through the trigger plate and the sensing plate, thereby avoiding the situation where the second pipe sensor has a small sensing range and cannot sense thinner pipes.

[0015] In a second aspect, the present invention further provides a pipe feeding device, comprising at least two sets of the above-mentioned pipe feeding and laying devices, and also comprising a feeding assembly, wherein the feeding assembly comprises: A bottom frame, the bottom frame is located at the feeding end of the second loading frame, a sliding plate is obliquely provided on the feeding side of the bottom frame, a limiting portion is provided on the end of the sliding plate, and a supporting guide rail is obliquely provided downward on the loading side of the bottom frame; At least two fixed plates, the material-loading surfaces of the fixed plates are step surfaces, and the fixed plates are arranged on the material-loading side of the base frame; At least two movable plates, the number of the movable plates is the same as that of the fixed plates, the feeding surface of the movable plates is a step surface, the movable plates are connected to a driving assembly, the movable plates are reciprocatingly arranged on the support rails, 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 pipes to move along the fixed plates; A third pipe sensor is arranged on the base frame and located at a stepped material level on the top of the fixed plate.

[0019] Furthermore, the fixing plate is connected to an adjustment component, the fixing plate is movably arranged on the base frame, and the moving direction of the fixing plate is perpendicular to the inclination direction of the support rail.

[0020] The present invention can adjust the relative position of the fixed plate with the movable plate by setting the position of the fixed plate to be adjustable, thereby ensuring that the movable plate can have sufficient contact area with the pipe regardless of the thickness of the profile, avoiding the pipe from rotating when the movable plate pushes the pipe, and improving the feeding efficiency.

When the first pipe is moved into place, the first loading rack stops conveying, the top plate rises, and the pipes located in front of the top plate on the first loading rack slide onto the second loading rack; S03: The second loading rack conveys the pipe to the feeding end, at which time the first loading rack stops conveying; S04: The movable plate transfers the pipes from the second loading rack to the fixed plate one by one through reciprocating movement, and pushes the pipes to move along the fixed plate toward the step material level at the top of the fixed plate; S05: When the pipe reaches the step level at the top of the fixed plate, if loading is not required, the movable plate and the second loading rack stop moving. If loading is required, the movable plate pushes the pipe to slide from the step level at the top of the fixed plate to the end of the sliding plate, and then the lifting platform rises to the set height, and the clamping roller clamps the profile and waits for transfer; after the profile slides to the end of the sliding plate, the movable plate continues to transport the pipe to the step level at the top of the fixed plate to wait for loading, and the second loading rack continues to transport the pipe to the feeding end. When there is no pipe on the second loading rack, repeat S02 to S03.

[0024] The present invention can shorten the waiting time when loading is required by ensuring that there are always pipes at the stepped material level on the top of the fixed plate, which is beneficial to improving production efficiency.

[0025] It can be seen from the above technical solutions that the present invention has the following advantages: The present invention provides a pipe feeding and paving device, a pipe feeding device and a pipe feeding method.

DETAILED DESCRIPTION

[0038] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical scheme of the present invention will be clearly and completely described below in conjunction with the drawings in this specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0039] Slender tubes have small deflection, and multiple tubes are entangled and twisted, which makes it impossible to load the tubes one by one. Manual assistance is required, and fully automated loading cannot be achieved. To solve this technical problem, in at least one of the following specific embodiments, the inventor adds a tube laying device before loading. By adopting the technical concept of allowing the tubes to slide under the action of their own weight, the entangled multiple tubes can be dispersed and laid flat, ensuring that the slender tubes are loaded one by one. Specific implementation method 1 like Figures 1 to 3 As shown, this specific embodiment provides a pipe loading and laying device, including a first loading rack 101, a second loading rack 102 and a lifting assembly, along the conveying direction, the second loading rack 102 is located in front of the first loading rack 101, the loading surface height of the second loading rack 102 is lower than the loading surface height of the first loading rack 101, the second loading rack 102 is connected to the first loading rack 101 through a sliding guide plate 104; the lifting assembly is arranged at the feeding end of the first loading rack 101, the lifting assembly includes a connected lifting plate 105 and a lifting cylinder 107, one top corner of the lifting plate 105 is arranged upward, the lifting cylinder 107 can drive the lifting plate 105 to reciprocate in the vertical direction, and the lifting plate 105 can extend and retract to the loading surface of the first loading rack 101.

[0041] This specific embodiment uses two loading racks of different heights and a lifting assembly. The lifting assembly can lift the pipe and slide it along its own inclined surface and the sliding guide plate 104 to the second loading rack 102, so as to achieve the sliding and dispersion of multiple slender pipes, achieve a flattening effect, avoid the entanglement of materials, and facilitate loading one by one.

[0042] like Figure 3 As shown, in this specific embodiment, in order to ensure a better material dividing effect, the top plate 105 adopts a triangular structure, and the top angle of the top plate 105 facing upward is an obtuse angle, which is 105° in this specific embodiment. The inclined surface of the top plate 105 extending toward the sliding guide plate 104 is parallel to the sliding guide plate 104.

[0043] like Figure 1 to Figure 2As shown, in this specific embodiment, the first loading rack 101 and the second loading rack 102 both include support racks, and the two support racks are connected to form an integrated structure. Two groups of conveying chains 103 are relatively arranged on each of the support racks, and the two groups of conveying chains 103 are connected to the same driving motor. Specifically, the conveying chain 103 includes a chain, a driving sprocket and a driven sprocket. The driving motor drives the driving shaft through a transmission belt. The driving shaft is rotatably arranged on the support rack, and a driving sprocket is arranged on the driving shaft, and a driven sprocket is rotatably arranged on the support rack; preferably, in order to evenly separate multiple pipes, two groups of the lifting components are arranged, and the two groups of the lifting components are relatively arranged on the support rack; it can be understood that in other embodiments, the number of conveying chains 103 can be adjusted as needed, and it is feasible to provide one or three.

[0044] like Figures 2 to 3 As shown, since the two groups of ejection assemblies are respectively provided with ejection cylinders 107, in order to ensure that the two ejection cylinders 107 rise and fall synchronously, and then ensure that multiple pipes can be neatly divided into two batches, and avoid the pipes from tilting and sliding down and causing entanglement again, in this specific embodiment, the ejection assembly also includes a support 106, and the support 106 is arranged on the support frame of the first loading rack 101, and the ejection cylinder 107 is arranged on the support 106. A synchronous rack 108 is vertically arranged on the support 106, and the synchronous rack 108 is meshed with a synchronous gear 110. The synchronous gears 110 of the two groups of the ejection assemblies are arranged on the same synchronous shaft 109, and the synchronous shaft 109 can be drivably arranged on the support frame; the telescopic movement of the two cylinders is balanced by the action of the synchronous rack 108 and the synchronous shaft 109, ensuring that the movement of the ejection plate 105 is consistent, and multiple pipes can be neatly divided into two rows of pipes in front of the ejection plate 105 and behind the ejection plate 105.

[0045] In order to realize the automatic lifting of the ejector plate 105, the present specific embodiment further includes a first pipe sensor 111, which is arranged at the feeding end of the support frame of the first loading rack 101. The first pipe sensor 111 adopts a photoelectric switch. Due to the different sizes and processing contents of different pipes, in order to make the beat of the ejector plate 105 material distribution suitable for the subsequent processing beat, it is necessary to adjust the number of pipes that the ejector plate 105 slides and transports at one time according to the requirements. For this purpose, a mounting is arranged at the feeding end of the support frame. A hole is provided in the mounting hole, and a bolt is provided in the mounting hole. The first tube sensor 111 is connected to the first loading rack 101 through the mounting hole. The mounting hole is a straight slot hole, and the length direction of the straight slot hole is parallel to the conveying direction. After such a setting, the installation position of the first tube sensor 111 can be adjusted, and then the number of tubes that slide down to the second loading rack 102 after the top plate 105 is raised can be adjusted. When more tubes need to slide down, the installation position of the first tube sensor 111 is adjusted backward along the conveying direction.

[0046] like Figure 4 As shown, due to the limited capacity of the second loading rack 102, when there is material at the feeding end of the second loading rack 102, the first loading rack 101 should stop conveying to avoid too many tubes on the second loading rack 102. For this reason, the feeding end of the second loading rack 102 is provided with a second tube sensor 112, which can determine whether there is a tube at the feeding end. The second tube sensor 112 adopts a proximity switch; due to the different thicknesses of the tubes, there may be a gap between adjacent tubes due to slippage during transportation, and the sensing range of the proximity switch is small. In order to ensure that the tubes are effectively sensed, a mounting seat is provided at the feeding end of the support frame of the second loading rack 102, and the second tube sensor 112 is provided on the mounting seat. A trigger plate 113 is also rotatably provided on the mounting seat, and the trigger plate 113 can be transmitted in a vertical plane. The trigger plate 113 is connected to a sensing plate 115 and a counterweight 114 in sequence to the inner side (close to the support frame). The second pipe sensor can sense the sensing plate 115. When no pipe arrives at the feeding end, the trigger plate 113 is tilted up under the action of the counterweight 114, and drives the sensing plate 115 to be located outside the sensing area of ​​the second pipe sensor 112. When the pipe arrives at 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 electronic control system controls the second loading rack 112 to stop conveying.

[0047] In order to avoid scratching the profile, in the present embodiment, nylon strips are provided on the two oblique sides of the ejector plate 105 and the slide guide plate 104, and rubber blocks are provided on the links of the chain.

[0048] The working process of this device is: A plurality of slender tubes (with entangled and twisted materials) are placed on the loading end of the first loading rack 101, and the first loading rack 101 transports 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 loading rack 101 stops transporting, and the top plate 105 rises to divide the tubes on the first loading rack 101 into two parts. The plurality of tubes in front of the top plate 105 slide along the inclined surface on the top plate 105 via the sliding guide plate 104 to the second loading rack 102. The sliding guide plate 104 provides a longer sliding distance, and the plurality of slender tubes no longer have twisted materials, and fall on the second loading rack 102 in a flat posture. The second loading rack 102 transports the tubes to its own feeding end until the second tube sensor 112 senses that the tubes are in place. The second loading rack 102 stops transporting and waits for loading. Specific implementation method 2 like Figures 5 to 8 As shown, this specific embodiment provides a pipe feeding device, including at least two groups of pipe feeding and paving devices 1 of specific embodiment one, and also including a feeding assembly, wherein the feeding assembly includes a base frame 2, a fixed plate 6 and a movable plate 5, wherein the fixed plates 6 and the movable plates 5 are the same in number and 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 obliquely arranged on the feeding side of the base frame 2, and a limiting portion 701 is arranged at the end of the sliding plate 7 to prevent the pipe from sliding off the sliding plate 7, and a support guide rail 201 is obliquely arranged 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 arranged, and the feeding surface of the fixed plate 6 is a step surface, and the fixed plate 6 is arranged on the feeding side of the base frame 2; the movable plate 5 is arranged on the feeding side of the base frame 2 The number of plates 5 and the fixed plates 6 is the same, the loading surface of the movable plate 5 is a stepped surface, the movable plate 5 is connected to a driving assembly, the movable plate 5 is reciprocatingly arranged on the supporting guide rail 201, the lower end of the movable plate 5 can extend into the lower side of the feeding end of the second loading rack 102, the movable plate 5 is arranged parallel to the fixed plate 6, and the movable 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 arranged on the base frame 2 and is located at the step material level at the top of the fixed plate 6. In this specific embodiment, the third pipe sensor 11 adopts a photoelectric switch and is arranged at an angle. Its light emitting direction is perpendicular to the supporting guide rail 201, and it can accurately sense whether there is material on the first step at the top of the fixed plate 6.

[0050] This specific embodiment can realize pipe loading one by one by providing a movable plate 5 and a fixed plate 6 with a stepped surface. Compared with the prior art that uses a cloth belt to load inclined materials, it can further avoid the situation where pipes are entangled and twisted during loading, thereby ensuring pipe loading one by one.

[0051] like Figure 7 and Figure 8As shown, in order to realize the reciprocating movement of the movable plate 5 and the synchronous movement of multiple movable plates 5, in this specific embodiment, multiple movable plates 5 are connected by a sliding beam 12, and the sliding beam 12 is connected to the support guide rail 201. A transmission support 13 is arranged on the sliding beam 12, and multiple transmission supports 13 are arranged. The driving assembly includes a feeding motor 16, and the feeding motor 16 drives a transmission shaft 15 through a transmission belt. The transmission shaft 15 is rotatably arranged on the base frame 2 through a bearing, and multiple eccentric wheels 14 are arranged on the transmission shaft 15. 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 are abutted against the corresponding transmission supports 13; when the feeding motor 16 drives the eccentric wheels 1 4 rotates, the eccentric wheel 14 can push the sliding beam 12 to move upward along the supporting guide rail 201 through the transmission support 13, thereby making the movable plate 5 move obliquely upward relative to the fixed plate 6, and pushing the pipe to move to the upper step through its own step surface. When the protrusion of the eccentric wheel 14 continues to rotate until it is located at the opposite end of the transmission support 13, the sliding beam 12 continues to slide obliquely downward along the supporting guide rail 201 under the action of its own and the movable plate 5 gravity. When the protrusion of the eccentric wheel 14 continues to rotate from the opposite end of the transmission support 13 until it abuts against the transmission support 13, the sliding beam 12 continues to slide obliquely upward along the supporting guide rail 201. With the continuous rotation of the eccentric wheel 14, the sliding beam 12 forms an up and down reciprocating movement along the supporting guide rail 201, and continuously pushes the pipe to move toward the top along the step of the fixed plate 6.

[0052] like Figure 8 and Figure 7 As shown, since there are round tubes, square tubes and rectangular tubes, and different tubes have different sizes, in order to avoid slipping when the movable plate 5 pushes the tube, the movable plate 5 should have enough contact area with the tube. Therefore, in order to improve the flexibility of use and ensure that different tubes can effectively push the loading, in this specific embodiment, the fixed plate 6 is connected with an adjustment component 8, and the fixed plate 6 is movably arranged on the base frame 2. The moving direction of the fixed plate 6 is perpendicular to the tilt direction of the support rail 201. The relative distance between the movable plate 5 and the fixed plate 6 in the tilt direction of the vertical support rail 201 can be adjusted by the adjustment component 8, so that the loading of official materials of various sizes can be guaranteed. The movable plate 5 has sufficient contact area to avoid slipping; further, the adjusting component 8 includes a rotating shaft 804, which is rotatably arranged on the upper part of the base frame 2. A plurality of adjusting gears 801 are arranged on the rotating shaft 804, which can respectively engage with the adjusting racks 802 on the corresponding fixed plates 6. The fixed plates 6 can move along the slide rail on the base frame 2. A reducer 803 is also connected to one end of the rotating shaft 804, and a handle is connected to the reduction input shaft. The reducer 803 is manually cranked to drive the plurality of fixed plates 6 to move synchronously. The reducer 803 adopts a worm gear reducer 803, which has a self-locking function to prevent the fixed plate 6 from moving in the opposite direction and driving the reducer 803 to rotate.

[0053] like Fig. 9 and Fig.10 As shown, in order to realize fully automatic loading, it is necessary to position the fallen profile to the clamping position of the cutting machine clamping assembly. For this purpose, the present specific embodiment also includes a centering assembly 3, which is 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 arranged on the lifting platform 301. The two clamping claws of the finger cylinder 306 are respectively connected to the clamping roller 303. The lifting platform 301 moves and the clamping roller 303 moves. The clamping action can accurately position the profile. Since the falling posture of the rectangular tube is uncertain, in order to further realize automatic loading, it is necessary to judge the loading posture of the rectangular tube. One clamping jaw of the finger cylinder 306 is connected to the body of the pull rope sensor, and the other clamping jaw is connected to the pull rope of the pull rope sensor 304. When the rectangular tube is in a vertical or horizontal state, there is a difference in the distance that the pull rope is pulled. Through the signal feedback of the pull rope sensor 304, the control system can know the loading posture of the rectangular tube, thereby adjusting the clamping posture of the cutting machine clamping assembly, thereby realizing fully automatic loading.

[0054] In this specific embodiment, in order to limit the position of the pipe, a limiting plate 4 is provided at the end of the pipe feeding and laying device along the length direction of the pipe.

[0055] In this specific embodiment, eight movable plates 5 and eight fixed plates 6 are provided respectively, three pipe feeding and paving devices 1 are provided, and three groups of conveying chains 103 are provided on the pipe feeding and paving devices 1 close to the limiting plates 4 .

[0056] In order to avoid scratching the profile, a nylon strip is provided on the slide plate 7. Specific implementation method three This specific embodiment provides a pipe feeding method, using the pipe feeding device of the specific embodiment 2, including the following steps: S01: placing a plurality of pipes on a plurality of first loading racks 101; S02: The first loading rack 101 transports the pipes. When the first pipe is moved into place, the first loading rack stops conveying, the top plate 105 rises, and the pipes on the first loading rack 101 located in front of the top plate 105 slide onto the second loading rack 102; S03: The second loading rack 102 transports the pipe to the feeding end, and at this time, the first loading rack 101 stops transporting; S04: The movable plate 5 transfers the pipes from the second loading rack 102 to the fixed plate 6 one by one by reciprocating movement, and pushes the pipes to move along the fixed plate 6 toward the top of the fixed plate 6; S05: When the pipe reaches the step level at the top of the fixed plate 6, if loading is not required, the movable plate 5 and the second loading rack 102 stop moving. If loading is required, the movable plate 5 moves upward to push the pipe to slide from the top of the fixed plate 6 to the end of the sliding plate 7, and then the lifting platform 301 is raised to the set height, and the clamping roller 303 clamps the profile and waits for transfer; when the profile slides to the end of the sliding plate 7, the movable plate 5 continues to transport the pipe to the step level at the top of the fixed plate 6 to wait for loading, and the second loading rack 102 continues to transport the pipe to the feeding end. When there is no pipe on the second loading rack 102, repeat S02 to S03.

[0058] In S05 of this specific embodiment, when the third pipe sensor 11 detects that there is material at the top and the control system sends a signal that loading is required, the loading motor 16 is activated to drive the movable plate 5 to move upward, pushing the pipe from the top of the fixed plate 6 through the sliding plate 7 to the limit portion 701; when the third pipe sensor 11 detects that there is material at the top, but the control system does not send a loading signal, the movable plate 5 and the second loading rack 102 both stop moving and wait for loading; when the third pipe sensor 11 cannot detect that there is material at the top, the movable plate 5 moves back and forth to push the pipe to the step level at the top of the fixed plate 6 until the third pipe sensor 11 detects that there is material at the top; this specific embodiment can shorten the waiting time when loading is required by ensuring that there is always pipe at the step level at the top of the fixed plate 6, which is beneficial to improving production efficiency.

[0059] To avoid placing too many pipes on the second loading rack 102, in the present specific embodiment, when there are no pipes on the second loading rack 102, that is, the second pipe sensor 112 does not sense the pipes within the set time after the second loading rack 102 is conveyed, the first loading rack 101 starts to convey the pipes, and after the pipes reach the set position, the first loading rack 101 stops conveying, the top plate 105 rises to realize material separation, and the second loading rack 102 conveys the pipes forward.

[0060] From the above specific implementations, it can be seen that the present invention has the following beneficial effects: 1. Through two feeding racks of different heights and the top material assembly, multiple slender pipes can be slid and dispersed during feeding and conveying, achieving a flat laying effect, avoiding the entanglement of twisted materials, and facilitating feeding one by one; 2. By setting the synchronous rack 108, gear and synchronous shaft 109, it can ensure that the two ejection cylinders 107 move synchronously and reach the same height, and ensure that the two ejection plates 105 act on the pipe at the same time; 3. By setting the position of the first sensor to be adjustable, the amount of material fed to the second loading rack 102 at one time can be adjusted according to the processing content and the size of the pipe, ensuring that it matches the processing rhythm of the cutting machine and is flexible to use; 4. The trigger plate 113 and the sensing plate 115 are used to make the second pipe sensor indirectly sense the pipe in place, so as to avoid the situation that the second pipe sensor has a small sensing range and cannot sense thin pipes; 5. By providing the movable plate 5 and the fixed plate 6 with stepped surfaces, pipe loading can be realized one by one, further avoiding the situation that pipes are entangled and twisted during loading, and ensuring pipe loading one by one; 6. Through the cooperation of a feeding motor 16 and multiple eccentric wheels 14, multiple moving plates 5 can be moved simultaneously, which improves the reliability of feeding and prevents the profile from slipping; 7. By setting the position of the fixed plate 6 to be adjustable, the relative position with the movable plate 5 can be adjusted to ensure that the movable plate 5 has sufficient contact area with the pipe regardless of the thickness of the profile, and avoid the pipe from rotating when the movable plate 5 pushes the pipe, thereby improving the feeding efficiency; 8. Through the centering component 3, on the one hand, the position of the profile on the lifting platform 301 can be adjusted, which is convenient for the cutting machine to accurately clamp and transport. On the other hand, the pull rope sensor 304 can determine the posture of the rectangular tube, which is convenient for the cutting machine to adjust the posture of the clamping device; 9. By ensuring that there are always pipes on the top of the fixed plate 6, the waiting time when loading is required can be shortened, which is conducive to improving production efficiency.
