The stacking assembly 900 is arranged at the stacking station 410, for stacking pipes and transferring the pipes to the first material distribution station 510; the lifting assembly 700 is arranged at the first material distribution station 510, for lifting the pipes in the first material distribution station 510; the pushing assembly 800 is arranged at the first material distribution station 510, for pushing down the pipes stacked in the first material distribution station 510; the blocking assembly 600 is slidably arranged at the second material distribution station 511, for intercepting the pipes at the second material distribution station 511 and releasing the pipes to the Loading station 512; the first drive device 300 is connected to all the stacking components 900 for driving the stacking components 900 to transfer pipes; the second drive device 310 is connected to all the blocking components 600 for adjusting the position of the blocking components 600; the third drive device 320 is connected to all the lifting components 700 for driving the lifting components 700 to lift the pipes; the loading component 140 is used to center the pipes at the loading station 512 and lift them to a set height for the feeding component 130 to grab.

[0026] The bed 100 serves as a stable basic support; the first guide rail 110 accurately guides the sliding of the feeding assembly 130 and the chuck assembly 200 to ensure that they can accurately cooperate during the pipe transportation and positioning process; the laser cutting assembly 120 is responsible for the pipe cutting task, and the loading assembly 140, the loading rack, etc. are responsible for the orderly loading and dividing operations of the pipes; in the loading rack, the stacking assembly 900 transfers the pipes to the first dividing station 510 under the drive of the first driving device 300, and the lifting assembly 700 lifts the pipes at the first dividing station 510 under the drive of the third driving device 320, and the blocking assembly 600 intercepts or releases the pipes at the second dividing station 511 under the control of the second driving device 310 to ensure The pipes can enter the loading station 512 accurately; through the close and orderly coordination between the components, from the initial stacking and transfer of the pipes by the stacking component 900, to the precise material division operation of the pipes by the lifting component 700, the pushing component 800, and the blocking component 600 at each station of the loading rack, and then to the loading component 140 to center the pipes and lift them to a suitable height for the feeding component 130 to grab, the feeding component 130 and the chuck component 200 clamp and transport the pipes, and cooperate with the laser cutting component 120 for cutting, which has changed the previous inefficient mode of relying on manual material division and loading, laid the foundation for the automation of pipe loading, improved loading efficiency, and can better meet the needs of industrial production for efficient operation.

[0027] During operation, a large number of pipes will be placed at the stacking station 410 where the stacking assembly 900 of the loading rack is located for centralized stacking. The first driving device 300 drives each stacking assembly 900 to transfer the pipes stacked at the stacking station 410 to the first material distribution station 510. When the pipes arrive at the first material distribution station 510, the third driving device 320 drives the lifting assembly 700 to work. The lifting assembly 700 lifts the pipes located in the first material distribution station 510, so that the pipes reach a height in the vertical direction that is convenient for the pushing assembly 800 to push the pipes down. ; Then, the pushing assembly 800 pushes down the stacked pipes with a certain thrust, so that only one row of pipes is left in the first distributing station 510, and the pushing assembly 800 is reset, and the lifting assembly 700 continues to lift the pipes to make them enter the second distributing station 511; the blocking assembly 600 is slidably arranged at the second distributing station 511, and is connected to the second driving device 310 through the transmission to adjust the size of the second distributing station 511 so that the second distributing station 511 can only accommodate one pipe to enter; when the pipe enters the second distributing station 511, the blocking assembly 600 is in the intercepting state, temporarily blocking a pipe here, and the rest of the pipes are reset away from the second feeding station 511 along with the lifting assembly 700, and return to the vicinity of the first feeding station 510 to wait for the next feeding operation; when the loading station 512 is ready, the blocking assembly 600 releases the pipe, allowing the pipe to enter the loading station 512; the loading assembly 140 performs a centering operation on the pipe located at the loading station 512, and lifts the centered pipe steadily to a suitable height, so that the pipe matches the grabbing position of the feeding assembly 130; the feeding assembly After grabbing the lifted pipe, the component 130 will slide along the first guide rail 110, driving the pipe to move to the vicinity of the laser cutting component 120. The chuck component 200 slides along the first guide rail 110 and cooperates with the feeding component 130. Through its own clamping mechanism, it will not be displaced or shaken during the laser cutting process, thereby ensuring the cutting accuracy; finally, the laser cutting component 120 accurately cuts the pipe that has been fixed by the chuck component 200, thereby completing the entire workflow of the pipe from stacking, loading to cutting.

[0028] Specifically, the laser cutting assembly 120, the feeding assembly 130 and the loading assembly 140 are prior art, and their specific structures and working principles are not described in detail.

[0029] The stacking of pipes may lack an effective limiting and regular mechanism, which may easily lead to disorderly stacking. Therefore, in one embodiment, the stacking assembly 900 includes a pull belt 910, a reel 920, a transition wheel 930 and a counterweight 940. The reel 920 is arranged on the guide frame 500 and can rotate relative to the guide frame 500. The transition wheel 930 is arranged on the guide frame 500 and can rotate relative to the guide frame 500. One end of the pull belt 910 is fixed to the frame 400, and the other end of the pull belt 910 passes around the transition wheel 930. The counterweight block 940 is arranged on the pull belt 910 and is located between the transition wheel 930 and the frame 400, so that the pull belt 910 naturally droops under the action of gravity to form a stacking space for stacking pipe materials. The reel 920 is connected to the first drive device 300 in a transmission manner. The reel 920 is used to reel in the pull belt 910, so that the pull belt 910 lifts the pipes in the stacking space and allows the pipes to enter the first material distribution station 510. By utilizing the stacking space formed by the natural drooping of the pull belt 910 under the action of gravity, a large number of pipes can be stacked conveniently and orderly. When the first drive device 300 drives the winding wheel 920 to wind up the pull belt 910, the pipe can be steadily lifted and smoothly entered into the first material distribution station 510, avoiding the tedious and inefficient manual stacking and transfer of pipes, and improving the preliminary preparation efficiency of loading and the overall production efficiency; the setting of the counterweight block 940 enables the pull belt 910 to maintain a natural drooping state, forming a stable stacking space. The pipes are stacked relatively regularly in this space, and can also better maintain stability during the subsequent transfer process, reducing damage to the pipes caused by shaking, collision, etc.

[0030] The rotational speeds of the various reel wheels 920 may be inconsistent, resulting in different pipe transfer speeds in different rack units, which in turn can cause confusion and accumulation of pipes when entering the first dispensing station 510. Therefore, in one embodiment, the first drive device 300 includes a first drive shaft 301 and a first motor 302, with all of the reel wheels 920 coaxially rotating with the first drive shaft 301, and the first motor 302 drivingly connected to the first drive shaft 301. The power of the first motor 302 is distributed to all the winding wheels 920 at the same time through the first drive shaft 301, so that the stacking components 900 of each material rack unit can move synchronously. The synchronous operation of the stacking components 900 of each material rack unit helps to ensure the consistency and orderliness of the pipes when they enter the material distribution station, and thus facilitates the subsequent lifting components 700, pushing components 800 and blocking components 600 to operate in a unified rhythm, thereby improving the coordination and accuracy of the entire loading process, and reducing problems such as pipe accumulation and jamming that may be caused by inconsistent actions of various parts; the structure is relatively simple and compact, reducing complex intermediate components such as transmission chains and belts, saving space, and reducing the overall volume and weight of the equipment.

[0031] During the process of the reel 920 reeling the drawstring 910, the drawstring 910 may be over-reeled, resulting in excessive tension in the drawstring 910, which may cause malfunctions such as the drawstring 910 breaking or the reel 920 getting stuck. Therefore, in one embodiment, the first drive device 300 further includes a limit assembly, which includes a first switch, a second switch, a sleeve, and a threaded sleeve. The threaded sleeve is disposed on the first drive shaft 301 and is coaxially rotatable with the first drive shaft 301. The first switch and the second switch are both disposed on one side of the first drive shaft 301. The sleeve is disposed between the first switch and the second switch, and the sleeve is threadedly connected to the threaded sleeve. The setting of the limit assembly can accurately control the rising limit and the falling limit of the pull belt 910, ensuring that the pull belt 910 will not exceed the reasonable range of movement when the reel 920 drives the pull belt 910 to lift or lower the pipe, avoiding excessive tension caused by excessive reeling of the pull belt 910, which may cause the pull belt 910 to break, the reel 920 to get stuck, and the excessive lowering of the pull belt 910 causing chaotic stacking of pipes and subsequent difficulty in normal transfer, thereby ensuring the stable operation of the stacking assembly 900 and the entire loading process, and improving the reliability of the equipment.

[0032] The pipe lacks a clear and reasonable movement path during the transfer process, and may roll randomly and deviate from the predetermined direction. Therefore, in one embodiment, the guide frame 500 includes a first guide portion 520, an arc transition portion 521, a second guide portion 522, a third guide portion 523, a fourth guide portion 524 and a stop portion 525, the first guide portion 520 is arranged to be tilted upward, the first guide portion 520 and the frame 400 are enclosed to form the stacking station 410, the first guide portion 520 and the second guide portion 522 are connected through the arc transition portion 521, the second guide portion 522 is arranged to be tilted downward, the third guide portion 523 is arranged to be tilted upward, the second guide portion 522 and the third guide portion 523 are enclosed to form the first material distribution station 510, the fourth guide portion 524 is arranged to be tilted downward, the fourth guide portion 524 and the blocking assembly 600 are enclosed to form the second material distribution station 511, and the stop portion 525 is arranged downstream of the fourth guide portion 524 to intercept the pipe falling from the fourth guide portion 524 to form the loading station 512. The multi-section structure of the guide frame 500 can accurately guide the pipe to roll in a preset direction and trajectory according to the movement characteristics of the pipe at different stages, ensuring that the pipe starts from the stacking station 410, passes through each material distribution station in an orderly manner, and finally reaches the loading station 512 accurately, avoiding disordered rolling and deviation from the path of the pipe during the transfer process; through the reasonable inclination setting of each guide part and the smooth connection of the arc transition part 521, the rolling of the pipe on the guide frame 500 is smoother and more natural, reducing jamming and resistance.

[0033] The pipes need to wait for the loading device to pick them up and are stranded in the loading station 512. After the material distribution is completed, the pipes fall directly, which may cause multiple pipes to enter the loading station 512 at the same time, causing material jamming or processing errors. Therefore, in one embodiment, the material blocking assembly 600 includes a first guide rail 110, a first slider 620, a material blocking bracket 630, a first cylinder 640 and a material blocking rod 650, wherein the first guide rail 110 is arranged on the material blocking bracket 630 and is arranged parallel to the fourth guide portion 524, the first slider 620 is arranged on the guide frame 500 and is slidably connected to the first guide rail 110, the first cylinder 640 is arranged on the material blocking bracket 630, the driving direction of the first cylinder 640 is arranged perpendicular to the fourth guide portion 524, the material blocking rod 650 is arranged on the driving part of the first cylinder 640, and the material blocking rod 650 and the fourth guide portion 524 enclose the second material distribution station 511. When the material stopping rod 650 is extended, it can effectively intercept the pipe and prevent it from continuing to fall; when loading is required, the cylinder drives the material stopping rod 650 to retract, and a single pipe can pass smoothly and enter the loading station 512, ensuring that only one pipe enters the processing link at a time, avoiding jamming or processing errors caused by multiple pipes entering at the same time, and significantly improving the accuracy of loading; by adjusting the position of the material stopping bracket 630, the distance between the material stopping rod 650 and the fourth guide part 524 can be changed to adapt to pipes of different diameters, thereby enhancing the versatility of the equipment and enabling the same set of loading racks to handle pipes of various specifications.

[0034] Uneven and asynchronous power transmission may cause the material stop bracket 630 to experience instability such as jamming and shaking during movement, affecting the accuracy and stability of the position adjustment of the material stop assembly 600. Therefore, in one embodiment, the second driving device 310 includes a second driving shaft 311, a handwheel 312, a plurality of first racks 313 and a plurality of first gears 314, the first racks 313 are arranged on the material stop bracket 630 in a one-to-one correspondence and are arranged parallel to the first guide rail 110, all of the first gears 314 are arranged to rotate coaxially with the second driving shaft 311, the first gears 314 are meshed with the first racks 313 in a one-to-one correspondence, and the handwheel 312 is drivingly connected to the second driving shaft 311. Through the meshing transmission of the first gear 314 and the first rack 313, the rotation of the handwheel 312 is converted into a linear movement of the material stopping bracket 630. When the handwheel 312 is rotated, the position of the material stopping bracket 630 can be accurately changed, and then the distance between the material stopping rod 650 and the fourth guide part 524 can be adjusted to ensure that pipes of different diameters can be accurately intercepted and released, thereby effectively improving the accuracy of loading. When the power is transmitted from the handwheel 312 to each first gear 314 via the second drive shaft 311, a synchronous and stable transmission effect can be maintained, thereby reducing the problems of unstable movement and jamming of the material stopping bracket 630 caused by inconsistent power transmission.

[0035] When lifting pipes, the push plate 720 may shake or shift, causing the pipes to be unable to rise or fall smoothly. Therefore, in one embodiment, the lifting assembly 700 includes a second guide rail 710, a second slider, and a push plate 720. The second guide rail 710 is disposed on the push plate 720 and is arranged parallel to the first guide portion 520. The second slider is disposed on the guide frame 500 and is slidably connected to the second guide rail 710. The push plate 720 moves up and down smoothly along the second guide rail 710, driving the pipes to achieve stable lifting and lowering movements, preventing shaking and shifting of the pipes during the lifting process, and ensuring that the pipes can enter the next workstation in an accurate posture. The lifting assembly 700 can adapt to the loading requirements of pipes of different specifications and quantities, enhancing the adaptability of the loading rack system to diverse production conditions and improving the versatility and practicality of the equipment. The second guide rail 710 is arranged parallel to the first guide portion 520, ensuring the movement continuity of the pipes throughout the entire loading process.

[0036] Multiple lifting assemblies 700 may experience uneven and asynchronous power transmission, resulting in instability such as jamming and shaking of the push plate 720 during the lifting process. Therefore, in one embodiment, the third drive device 320 includes a third drive shaft 321, a second motor 322, a plurality of second racks 323, and a plurality of second gears 324. The second racks 323 are arranged on the push plate 720 in a one-to-one correspondence and are arranged parallel to the second guide rail 710. All of the second gears 324 are arranged to rotate coaxially with the third drive shaft 321. The second gears 324 are meshed with the second racks 323 in a one-to-one correspondence. The second motor 322 is drivingly connected to the third drive shaft 321. The meshing transmission of the second gear 324 and the second rack 323 accurately converts the rotational power of the second motor 322 into the linear motion of the push plate 720, and can accurately adjust the lifting height of the push plate 720, thereby realizing precise control of the position of the pipe at the material dividing station and the like; all the second gears 324 are arranged to rotate coaxially with the third drive shaft 321, so that the power output by the second motor 322 can be evenly and stably transmitted to each second gear 324 through the third drive shaft 321, avoiding problems such as jamming and shaking of the push plate 720 caused by uneven power transmission, ensuring the stability of the push plate 720 during the lifting process, enabling the pipe to stably complete position adjustment, and improving the reliability and efficiency of the entire loading process.

[0037] Multiple pipes may be stacked in the first material distribution station 510 and enter the second material distribution station 511 at the same time as the lifting assembly 700 is lifted, causing material jamming or processing errors. Therefore, in one embodiment, the pushing assembly 800 includes a pushing block 810, a second cylinder 820, an induction plate 830 and a sensor 840, the second cylinder 820 is arranged on the guide frame 500, the driving direction of the second cylinder 820 is arranged parallel to the fourth guide portion 524, the pushing block 810 is arranged on the driving portion of the first cylinder 640, the induction plate 830 is arranged on the lifting assembly 700, the sensor 840 is arranged on the guide frame 500, the sensor 840 is used to cooperate with the induction plate 830, and the sensor 840 is electrically connected to the second cylinder 820. By driving the push block 810 and the fourth guide part 524 to move parallel to each other through the second cylinder 820, the excess pipes can be accurately pushed off, leaving only a single pipe to enter the next workstation; when the lifting component 700 lifts the pipe to the set height, the sensor 840 and the induction plate 830 cooperate with the trigger signal to control the action of the second cylinder 820, and the push block 810 pushes the excess pipe away to avoid jamming or processing errors caused by multiple pipes entering at the same time, thereby improving the accuracy of loading; when the lifting component 700 rises to a specific position, the induction plate triggers the sensor, and the sensor immediately transmits the signal to the second cylinder, driving the push block to perform the pushing action, thereby improving loading efficiency and reducing labor costs.

[0038] Specifically, the lifting assembly 700 also includes an adjustment rod, one end of which is hingedly connected to the push plate via a bolt. The sensor plate is disposed at the other end of the adjustment rod. The adjustment rod allows the position of the sensor plate to be flexibly adjusted according to the pipe diameter, accommodating pipes of varying specifications and significantly improving the versatility of the device.

[0039] The fixed portion of the feeding assembly 130 inserted into the pipe material cannot be cut during the cutting process, which leads to waste of pipe material tails. Therefore, in one embodiment, the chuck assembly 200 includes a mounting seat 210, a chuck body 220, a fourth drive device 230 and two sets of material pulling jaws 240. The mounting seat 210 is slidably connected to the first guide rail 110. The fourth drive device 230 drives the mounting seat 210 to translate along the first guide rail 110. The chuck body 220 is disposed on the mounting seat 210 to assist in supporting the pipe material. Each set of material pulling jaws 240 includes a jaw body 241 and a fifth drive device 242. The fifth drive device 242 is disposed on one side of the chuck body 220. The jaw body 241 is disposed on the driving portion of the fifth drive device 242. A clamping space is defined between the two material pulling jaws 240. The two fifth drive devices 242 drive the two jaw bodies 241 to move closer or further away from each other, thereby adjusting the width of the clamping space. The fifth driving device 242 drives the two claw bodies 241 to move closer to or away from each other, so as to adjust the width of the clamping space, thereby realizing the clamping and loosening of the tail of the pipe material, and effectively fixing the tail of the pipe material; the fourth driving device 230 drives the mounting seat to drive the mounting seat 210 to move horizontally along the first guide rail 110, so as to cooperate with the laser cutting head to cut the tail of the pipe material; by clamping the tail of the pipe material through the pulling claw 240, the fourth driving device 230 drives the chuck body 220 to move horizontally, so that the laser cutting head can effectively cut the material at the tail of the pipe material.

[0040] Specifically, the fourth driving device 230 includes a fourth gear, a fourth rack and a fourth motor. The fourth rack is arranged on the bed 100 and parallel to the first guide rail 110. The fourth motor is arranged on the mounting seat 210. The fourth gear and the driving part of the fourth motor are coaxially rotated, and the fourth gear and the fourth rack are meshed; the second driving device is a third cylinder, and the third cylinder is fixed on the chuck body. The telescopic part of the third cylinder is fixed to the claw body; the chuck body is existing technology, and its specific structure and working principle are no longer repeated.
