Detailed Implementation

[0022] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages mentioned herein do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0023] Currently, in the pipe cutting process, pipe feeding is an important and frequent operation. Traditional pipe feeding methods often have many shortcomings. For example, manual feeding is inefficient, labor-intensive, and prone to operational errors, affecting production continuity and product quality. Some simple mechanical auxiliary feeding devices may only achieve a single function, such as simple stacking or pushing, lacking systematic integration and failing to meet the needs of precise, orderly, and efficient pipe feeding in complex production processes.

[0024] Therefore, this utility model proposes a feeding rack, referring to... Figures 1-5It includes a first driving device 100, a second driving device 200, a third driving device 300, and at least three sets of spaced-apart material rack units. Each set of material rack units includes a frame 400, a guide frame 500, a material blocking assembly 600, a lifting assembly 700, a pushing assembly 800, and a stacking assembly 900. The guide frame 500 is sequentially provided with a first material dispensing station 510, a second material dispensing station 511, and a loading station 512. A stacking station 410 is provided between the frame 400 and the guide frame 500. The stacking assembly 900 is located at the stacking station 410 and is used to stack pipes and transfer them to the first material dispensing station 510. The lifting assembly 700 is located at the first material dispensing station 510 and is used to lift the first material dispensing station 510. The pipes in the first material distribution station 510; the pushing component 800 is disposed in the first material distribution station 510 and is used to push down the stacked pipes in the first material distribution station 510; the blocking component 600 is slidably disposed in the second material distribution station 511 and is used to intercept the pipes at the second material distribution station 511 and release the pipes to the loading station 512; the first driving device 100 is drivenly connected to all the stacking components 900 and is used to drive the stacking components 900 to transfer the pipes; the second driving device 200 is drivenly connected to all the blocking components 600 and is used to adjust the position of the blocking components 600; the third driving device 300 is drivenly connected to all the lifting components 700 and is used to drive the lifting components 700 to lift the pipes.

[0025] The frame 400 provides a stable support structure; the guide frame 500 provides path guidance for the flow of pipes, avoiding the disorder of pipe flow; the stacking assembly 900 can stack a large number of pipes, and under the drive of the first drive device 100, it smoothly transfers the pipes to the first dispensing station 510; the lifting assembly 700, driven by the third drive device 300, lifts the pipes in the first dispensing station 510 to a suitable height at different stages, and cooperates with the pushing assembly 800 to complete the sorting and pushing of the pipes, ensuring that the pipes flow in the set order and position; the blocking assembly 600, driven by the second drive device 200, controls the flow direction of the pipes at the second dispensing station 511. This invention, through the cooperation of the lifting component 700, the pushing component 800, and the blocking component 600, can gradually organize and precisely control the pipes, ensuring that only one pipe is delivered to the loading station 512 at a time. This guarantees the accuracy of the loading and provides a guarantee for subsequent processing equipment to accurately grasp the pipes for processing, thus helping to improve the stability of product quality. It also reduces the need for frequent manual intervention in the material feeding operation, thereby reducing labor costs. Furthermore, it reduces processing errors and product scrap that may be caused by chaotic pipe loading, indirectly reducing production costs.

[0026] During operation, the stacking assembly 900, driven by the first drive device 100, transfers a large number of pipes pre-stacked at the stacking station 410 to the first sorting station 510; the lifting assembly 700, driven by the third drive device 300, lifts the pipes and, in conjunction with the pushing assembly 800, pushes down and organizes the excess pipes, leaving only one row of pipes at the first sorting station 510; the pipes, continuously pushed by the lifting assembly 700, roll along the guide frame 500 to the second sorting station 511; the blocking assembly 600, controlled by the second drive device 200, intercepts the pipes, allowing only one pipe to remain temporarily, thus achieving precise control over the number of pipes; finally, when the loading conditions are met, the blocking assembly 600 releases the pipe, allowing it to enter the loading station 512 to complete the loading. Each drive unit and its corresponding component are connected by a transmission mechanism and operate repeatedly in a preset sequence and logic to form a stable, efficient and precise pipe feeding cycle system, which continuously provides an orderly supply of pipes for subsequent production and processing stages.

[0027] Pipe stacking may lack effective limiting and organizing mechanisms, easily leading to disorderly stacking. Therefore, in one embodiment, the stacking assembly 900 includes a pull belt 910, a take-up reel 920, a transition reel 930, and a counterweight 940. The take-up reel 920 is mounted on the guide frame 500 and can rotate relative to the guide frame 500. The transition reel 930 is mounted 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 reel 930. The pull belt 910 is then connected to the take-up reel 920. The counterweight 940 is disposed on the pull belt 910 and located between the transition wheel 930 and the frame 400, so that the pull belt 910 hangs down naturally under the action of gravity to form a stacking space for stacking pipe materials. The take-up reel 920 is connected to the first drive device 100 for transmission. The take-up reel 920 is used to wind up the pull belt 910, so that the pull belt 910 lifts the pipe materials in the stacking space and allows the pipe materials to enter the first material distribution station 510. The material stacking space formed by the natural drooping of the pull belt 910 under gravity allows for convenient and orderly stacking of a large number of pipes. When the first drive device 100 drives the winding wheel 920 to wind up the pull belt 910, it can stably lift the pipes and smoothly enter the first material distribution station 510, avoiding the tediousness and inefficiency of manual stacking and transfer of pipes, and improving the efficiency of pre-feeding preparation and overall production efficiency. The counterweight 940 allows the pull belt 910 to maintain a natural drooping state, forming a stable material stacking space. The pipes are stacked relatively neatly in this space, and can maintain stability better during subsequent transfer, reducing damage to the pipes caused by shaking, collision, etc.

[0028] The rotational speeds of the various take-up reels 920 may be inconsistent, resulting in different transfer speeds of the tubing in different material rack units. This can cause the tubing to become disordered and piled up when it enters the first material distribution station 510. Therefore, in one embodiment, the first drive device 100 includes a first drive shaft 110 and a first motor 120. All the take-up reels 920 are coaxially rotatably arranged with the first drive shaft 110, and the first motor 120 is drivenly connected to the first drive shaft 110. The power of the first motor 120 is simultaneously distributed to all the take-up reels 920 via the first drive shaft 110, enabling the stacking components 900 of each material rack unit to operate 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 entering the sorting station. This facilitates the coordinated operation of the subsequent lifting component 700, pushing component 800, and blocking component 600 at a unified rhythm, improving the coordination and accuracy of the entire feeding process and reducing problems such as pipe accumulation and jamming 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 size and weight of the equipment.

[0029] During the winding process of the take-up reel 920 winding the pull belt 910, the pull belt 910 may be over-wound, resulting in excessive tension on the pull belt 910, which may cause malfunctions such as breakage of the pull belt 910 or jamming of the take-up reel 920. Therefore, in one embodiment, the first drive device 100 further includes a limiting component 130, which includes a first switch 131, a second switch 132, a bushing 133, and a threaded sleeve 134. The threaded sleeve 134 is disposed on the first drive shaft 110 and rotates coaxially with the first drive shaft 110. The first switch 131 and the second switch 132 are both disposed on one side of the first drive shaft 110, and the bushing 133 is disposed between the first switch 131 and the second switch 132. The bushing 133 is threadedly connected to the threaded sleeve 134. The limit component 130 can precisely control the upper and lower limits of the pull belt 910, ensuring that the pull belt 910 does not exceed the reasonable range of motion when the winding wheel 920 drives the pull belt 910 to lift or lower the pipe. This avoids problems such as excessive tension caused by over-winding of the pull belt 910, which may lead to breakage of the pull belt 910 or jamming of the winding wheel 920, as well as situations where excessive lowering of the pull belt 910 causes disordered pipe stacking and difficulty in subsequent normal transfer. This ensures the stable operation of the stacking component 900 and the entire feeding process, and improves the reliability of the equipment.

[0030] If the pipes lack a clear and reasonable movement path during the transfer process, they may roll randomly or deviate from the intended 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 inclined upward, and the first guide portion 520 and the frame 400 enclose the material 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 inclined downward, and the third guide portion 523 is inclined upward. The second guide portion 522 and the third guide portion 523 enclose the first material distributing station 510. The fourth guide portion 524 is inclined downward, and the fourth guide portion 524 and the material blocking assembly 600 enclose the second material distributing station 511. The stop portion 525 is located 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-segment 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 distribution station in an orderly manner, and finally arrives accurately at the loading station 512, avoiding disorderly rolling and deviation from the path of the pipe during the transfer process; through the reasonable tilt 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.

[0031] The pipes need to wait for the feeding device to clamp them and remain in the feeding station 512. If the pipes fall directly after the material is divided, multiple pipes may enter the feeding station 512 at the same time, causing jamming or processing errors. Therefore, in one embodiment, the material blocking assembly 600 includes a first guide rail, a first slider 620, a material blocking bracket 630, a first cylinder 640, and a material blocking rod 650. The first guide rail is disposed on the material blocking bracket 630 and is parallel to the fourth guide portion 524. The first slider 620 is disposed on the guide frame 500 and is slidably connected to the first guide rail. The first cylinder 640 is disposed on the material blocking bracket 630, and the driving direction of the first cylinder 640 is perpendicular to the fourth guide portion 524. The material blocking rod 650 is disposed on the driving part of the first cylinder 640. The material blocking rod 650 and the fourth guide portion 524 enclose the second material dividing station 511. When the baffle rod 650 extends, it can effectively intercept the pipe and prevent it from falling further. When feeding is required, the cylinder drives the baffle rod 650 to retract, allowing a single pipe to pass smoothly into the feeding station 512. This ensures that only one pipe enters the processing stage at a time, avoiding jamming or processing errors caused by multiple pipes entering at the same time, and significantly improving the accuracy of feeding. By adjusting the position of the baffle bracket 630, the distance between the baffle rod 650 and the fourth guide part 524 can be changed, thereby adapting to pipes of different diameters, enhancing the versatility of the equipment, and enabling the same feeding rack to handle multiple specifications of pipes.

[0032] Uneven or asynchronous power transmission may cause the stop bracket 630 to experience instability such as jamming or shaking during movement, affecting the accuracy and stability of the position adjustment of the stop assembly 600. Therefore, in one embodiment, the second drive device 200 includes a second drive shaft 210, a handwheel 220, a plurality of first racks 230, and a plurality of first gears 240. The first racks 230 are correspondingly arranged on the stop bracket 630 and parallel to the first guide rail. All the first gears 240 are coaxially rotatably arranged with the second drive shaft 210, and the first gears 240 mesh with the first racks 230 correspondingly. The handwheel 220 is drivenly connected to the second drive shaft 210. Through the meshing transmission of the first gear 240 and the first rack 230, the rotation of the handwheel 220 is converted into the linear movement of the stop bracket 630. When the handwheel 220 is rotated, the position of the stop bracket 630 can be precisely changed, thereby adjusting the distance between the stop rod 650 and the fourth guide part 524, ensuring that pipes of different diameters can be accurately intercepted and released, effectively improving the accuracy of feeding. When the power is transmitted from the handwheel 220 to each of the first gears 240 through the second drive shaft 210, a synchronous and stable transmission effect can be maintained, reducing problems such as unstable movement and jamming of the stop bracket 630 caused by inconsistent power transmission.

[0033] When lifting the pipe, the push plate 720 may sway or shift, causing the pipe to rise or fall unevenly. 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 mounted on the push plate 720 and parallel to the first guide portion 520. The second slider is mounted on the guide frame 500 and slidably connected to the second guide rail 710. The push plate 720 moves smoothly up and down along the second guide rail 710, driving the pipe to achieve stable lifting and lowering, avoiding swaying or shifting during lifting, and ensuring the pipe enters the next workstation with an accurate posture. The lifting assembly 700 can adapt to the feeding requirements of pipes of different specifications and quantities, enhancing the adaptability of the feeding rack system to diverse production conditions and improving the equipment's versatility and practicality. The parallel arrangement of the second guide rail 710 and the first guide portion 520 ensures the continuity of the pipe's movement throughout the feeding process.

[0034] The multiple lifting components 700 may experience uneven or asynchronous power transmission, leading to instability such as jamming and shaking of the push plate 720 during lifting. Therefore, in one embodiment, the third drive device 300 includes a third drive shaft 310, a second motor 320, multiple second racks 330, and multiple second gears 340. The second racks 330 are correspondingly arranged on the push plate 720 and parallel to the second guide rail 710. All the second gears 340 are coaxially rotatably arranged with the third drive shaft 310, and the second gears 340 mesh with the second racks 330. The second motor 320 is drivenly connected to the third drive shaft 310. The meshing transmission between the second gear 340 and the second rack 330 precisely converts the rotational power of the second motor 320 into the linear motion of the push plate 720, enabling precise adjustment of the lifting height of the push plate 720 and thus achieving precise control of the pipe's position at the material distribution station. All the second gears 340 are coaxially rotated with the third drive shaft 310, ensuring that the power output by the second motor 320 is evenly and stably transmitted to each second gear 340 through the third drive shaft 310. This avoids problems such as jamming and shaking of the push plate 720 caused by uneven power transmission, ensuring the stability of the push plate during lifting and lowering, allowing the pipe to stably complete the position adjustment, and improving the reliability and efficiency of the entire feeding process.

[0035] Multiple pipes may be stacked at the first material distribution station 510, and simultaneously enter the second material distribution station 511 as the lifting assembly raises them, causing jamming or processing errors. Therefore, in one embodiment, the pushing assembly includes a pushing block, a second cylinder, a sensing plate, and a sensor. The second cylinder is mounted on the guide frame 500, and its driving direction is parallel to the fourth guide portion 524. The pushing block is mounted on the driving portion of the first cylinder. The sensing plate is mounted on the lifting assembly, and the sensor is mounted on the guide frame 500. The sensor is used to cooperate with the sensing plate, and the sensor is electrically connected to the second cylinder. The second cylinder drives the pusher block to move parallel to the fourth guide section, which can accurately push off excess pipes, leaving only a single pipe to enter the next station. When the lifting assembly raises the pipe to the set height, the sensor and the sensing plate trigger a signal to control the second cylinder to move. The pusher block pushes the excess pipe away, avoiding jamming or processing errors caused by multiple pipes entering at the same time, thus improving the accuracy of loading. When the lifting assembly rises to a specific position, the sensing plate triggers the sensor, which immediately transmits a signal to the second cylinder, driving the pusher block to perform the pushing action, improving loading efficiency and reducing labor costs.

[0036] Specifically, the lifting assembly also includes an adjusting rod, one end of which is hinged to the push plate by bolts, and the sensing element is disposed at the other end of the adjusting rod. By adjusting the rod, the position of the sensing element can be flexibly adjusted according to the pipe diameter, adapting to different pipe specifications and significantly improving the equipment's versatility.

[0037] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
