Description

Technical Field

[0001] This application belongs to the field of laser cutting, specifically relating to a pipe loading and unloading system. Background Technology

[0002] With the increasing demand for automation in the machining industry, the pipe processing industry is increasingly seeking efficient and orderly pipe storage and loading / unloading systems. Currently, most laser pipe cutting machines on the market rely on manual management of raw pipe materials, which are often stacked haphazardly. This not only occupies a large amount of space but also requires frequent handling and rearrangement during retrieval, leading to low production efficiency and increased operating costs. Furthermore, manual operation is prone to introducing errors, affecting processing accuracy, and makes it difficult to achieve collaborative operation between multiple machines.

[0003] While some existing automated storage systems can centrally store pipes, traditional storage devices are mostly single-layer or simple multi-layer structures, failing to fully utilize vertical space and resulting in insufficient storage density. Furthermore, feeding and unloading typically rely on the same conveyor mechanism, easily causing operational conflicts and affecting overall system efficiency. The lack of reliable limiting and docking structures during material frame movement makes them prone to displacement or detachment, impacting the stability of automated operation. Existing systems struggle to adapt to the collaborative operation of multiple pipe cutting machines, failing to achieve flexible task scheduling and material allocation.

[0004] Therefore, there is an urgent need for a high-efficiency system that can achieve orderly storage of pipes, automated loading and unloading, and support multi-machine collaborative operation, in order to solve the problems of chaotic storage management, high labor costs, and low equipment utilization in existing technologies.

[0015] Preferably, the material frame is provided with limiting grooves at both ends, and the material frame hanging plate is provided with a locking protrusion adapted to the limiting groove.

[0017] Preferably, both the feeding assembly and the unloading assembly include a support for receiving the material frame. The support is provided with a third drive assembly that is connected to the guide wheel via a transmission.

[0021] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0022] This application's solution utilizes a storage device for the orderly storage of pipes. Pipes are stored in baskets on a pipe placement rack, which has multiple placement positions for these baskets, allowing for the simultaneous storage of multiple sets of pipes. When pipes need to be loaded onto the rack, a forklift or overhead crane places the basket containing the pipes into the feeding assembly of a pipe conveying device. A horizontal moving device and a lifting device then remove the basket from the feeding assembly and transfer it to the pipe placement rack, achieving centralized storage and management of the pipes. When pipes need to be removed for processing, the horizontal moving device moves the basket to the appropriate placement position, removes it, and then the lifting device moves the basket to the unloading assembly for final removal. This centralized management of pipes through the placement rack ensures orderly arrangement, facilitating storage and subsequent use. Furthermore, this method utilizes a feeding component and a discharging component to respectively realize the loading and unloading of pipes. While the feeding device is transferring the pipes in the discharging component, the feeding component can simultaneously feed the pipe placement rack, which helps to improve the overall working efficiency of the system.

[0023] Meanwhile, the present application solution uses a feeding device to remove and transfer the pipes located in the feeding component, and the feeding device can transfer the pipes to different pipe cutting machines, which is conducive to improving the working efficiency of the system. Since the feeding device only moves between the feeding component and the pipe cutting machine, it will not affect the operation of the storage tower and the feeding component. The overall structural layout is more reasonable and realizes the regional division of system functions. Attached Figure Description

[0053] like Figures 1 to 7 As shown, this application provides a pipe loading and unloading system, including:

[0054] The storage device 1 includes a storage tower 110 for storing pipes. The storage tower 110 is provided with a pipe placement rack 120 and a horizontal moving device 140 and a lifting device 130 that move along the pipe placement rack 120. The storage device 1 also includes a material frame 150 for loading pipes. The horizontal moving device 140 and the lifting device 130 drive the material frame 150 to move to different placement positions 121 of the pipe placement rack 120 or take it out from the placement position 121.

[0055] Pipe conveying device 2, which includes a feeding component 210 and a discharging component 220, a horizontal moving device 140 and a lifting device 130 to take the material frame 150 out of the feeding component 210 or place the material frame 150 in the discharging component 220.

[0056] The feeding device 3 includes a material picking component 310 and a transfer component 320. The material picking component 310 is used to pick up the pipe from the unloading component 220, and the transfer component 320 is used to transfer the pipe to the pipe cutting machine 4. The transfer component 320 moves between the unloading component 220 and multiple pipe cutting machines 4.

[0057] This application solution uses a storage device 1 to store pipes in an orderly manner. The pipes are stored in a pipe placement rack 120 via a material frame 150. The pipe placement rack 120 has multiple placement positions 121 for receiving the material frames 150, allowing for the simultaneous storage of multiple sets of pipes. When pipes need to be loaded onto the pipe placement rack 120, a forklift or overhead crane places the material frame 150 containing the pipes into the feeding component 210 of the pipe conveying device 2. The material frame 150 is then removed from the feeding component 210 and conveyed to the pipe placement rack 120 via a horizontal moving device 140 and a lifting device 130, thus achieving centralized placement and management of the pipes. When pipes need to be removed for processing, the material frame 150 is moved to the corresponding placement position 121 via the horizontal moving device 140 and removed. The material frame 150 is then moved to the unloading component 220 via the lifting device 130, thus removing the pipes. Pipes are centrally managed using the pipe placement rack 120, enabling them to be arranged in an orderly manner for easy storage and subsequent use. This method utilizes the feeding component 210 and the unloading component 220 to respectively load and unload pipes. While the loading device 3 is transferring pipes within the unloading component 220, the feeding component 210 can simultaneously load pipes into the pipe placement rack 120, thus improving the overall system efficiency.

[0058] Meanwhile, the present application scheme uses the feeding device 3 to take out and transfer the pipes located in the feeding component 210, and the feeding device 3 can transfer the pipes to different pipe cutting machines 4, which is conducive to improving the working efficiency of the system. Since the feeding device 3 only moves between the feeding component 210 and the pipe cutting machine 4, it will not affect the operation of the storage tower 110 and the feeding component 210. The overall structural layout is more reasonable and realizes the regional division of system functions.

[0059] In one embodiment, such as Figures 2 to 5 As shown, the lifting device 130 includes a vertical slide rail 131 disposed on the pipe placement rack 120, and the horizontal moving device 140 includes a horizontal slide rail 141 disposed on the pipe placement rack 120, and the horizontal slide rail 141 moves up and down along the vertical slide rail 131 via the mounting base 160 located on the vertical slide rail 131.

[0060] The storage device 1 also includes a material frame hanging plate 170 that is slidably connected to the transverse slide rail 141. The lifting device 130 includes a first driving component 132 that drives the material frame hanging plate 170 to move along the vertical slide rail 131. The horizontal moving device 140 includes a second driving component 142 that drives the material frame hanging plate 170 to move along the transverse slide rail 141.

[0061] This application's solution, through the coordinated use of vertical slide rails 131 and horizontal slide rails 141, not only achieves precise positioning of the material frame 150 within the storage tower 110, but also improves the system's space utilization. The sliding connection between the mounting base 160 of the vertical slide rail 131 and the horizontal slide rail 141 allows the material frame 150 to move flexibly in three-dimensional space, adapting to placement positions 121 at different heights. The sliding connection between the material frame hanging plate 170 and the horizontal slide rail 141 further enhances the stability and reliability of the device, preventing the material frame 150 from shifting or shaking due to uneven force during movement. Furthermore, this design facilitates future maintenance and expansion; the slide rail length can be adjusted or the number of placement positions 121 can be increased according to actual needs, demonstrating high flexibility and adaptability.

[0062] Specifically, such as Figure 2 As shown, in this design, the pipe placement rack 120 has two rows of placement positions 121, with each row having multiple placement positions 121 from top to bottom. The vertical slide rail 131 is located in the middle of the pipe placement rack 120, between the two rows of placement positions 121. The horizontal slide rail 141 is perpendicular to the vertical slide rail 131 and extends to the two rows of placement positions 121 on both sides, allowing the material frame hanging plate 170 to move horizontally to the placement positions 121 on both sides. A sliding connection is provided between the mounting base 160 and the vertical slide rail 131, which can be achieved through a combination of a sliding groove and pulleys. The material frame hanging plate 170 can also be slidably connected to the horizontal slide rail 141 via a slider, and the mounting base 160 can cooperate with the vertical slide rail 131 to achieve a good guiding effect during movement.

[0063] Furthermore, the first drive assembly 132 includes a first drive motor 1321 and a first synchronous shaft 1322 disposed on both sides of the first drive motor 1321. The end of the first synchronous shaft 1322 is provided with a sprocket and chain assembly, and the chain is parallel to the vertical slide rail 131.

[0064] Furthermore, the second drive assembly 142 includes a second drive motor 1421 and a second synchronous shaft 1422 disposed on both sides of the second drive motor 1421. The end of the second synchronous shaft 1422 is provided with a drive wheel 1423 that is connected to it for transmission. The second drive assembly 142 also includes a driven wheel 1424 that cooperates with the drive wheel 1423. Both the drive wheel 1423 and the driven wheel 1424 are fixed to the mounting base 160. The drive wheel 1423 and the driven wheel 1424 are connected by a transmission chain 1425, and the end of the transmission chain 1425 is fixed to the material frame hanging plate 170.

[0065] This application's solution employs a combination of a first drive motor 1321, a first synchronous shaft 1322, and a chain and sprocket for vertical movement, ensuring the synchronicity and stability of the mounting base 160 during lifting and lowering, and avoiding jamming or vibration caused by uneven force on one side. The design of the sprocket and chain assembly further enhances the reliability of the transmission, making it suitable for high-frequency, high-load operating environments. It should be noted that, combined with... Figure 2 As shown, the chain is designed with open ends, with its ends fixedly connected to the outer side of the mounting base 160 to drive its movement. The lateral movement device, through the cooperation of the second drive motor 1421, the drive wheel 1423, the driven wheel 1424, and the transmission chain 1425, achieves precise horizontal movement of the material frame hanging plate 170. It features high transmission efficiency, low noise, and the transmission chain 1425 provides a certain degree of cushioning, reducing impact on the material frame 150. This drive method has a compact structure, low maintenance costs, and is suitable for long-term continuous operation, significantly improving the system's stability and service life.

[0066] In this embodiment, the first drive motor 1321 is located at the bottom of the storage tower 110, which helps stabilize the center of gravity of the storage tower 110 and facilitates assembly and maintenance. In this embodiment, the mounting base 160 includes a portion located at the center connected to the vertical slide rail 131 and extending to both sides to connect with chains on both sides. The chains on both sides help improve the smoothness of movement and do not obstruct the loading and unloading process of the pipes.

[0067] And specifically, such as Figure 5 As shown, the two opposite mounting seats 160 of the pipe placement rack 120 are connected by a reinforcing beam 143. The second drive motor 1421 is arranged at the reinforcing beam 143, and the second synchronous shaft 1422 extends to the mounting seats 160 on both sides to connect with the drive wheel 1423 located in the center of the mounting seat 160. This enables one second drive motor 1421 to drive the two drive wheels 1423 to rotate simultaneously, so that the oppositely arranged material frame hanging plates 170 can move synchronously and stably.

[0068] Preferably, such as Figure 4 As shown, the material frame 150 has limiting grooves 151 at both ends, and the material frame hanging plate 170 has a locking protrusion 171 that matches the limiting groove 151. The locking protrusion 171 engages with the limiting groove 151 so that the material frame hanging plate 170 drives the corresponding material frame 150 to move.

[0069] This application's solution achieves rapid docking and stable fixation between the material frame 150 and the material frame mounting plate 170 through the cooperative design of the limiting groove 151 and the locking protrusion 171. The limiting groove 151 is designed with a V-shaped or U-shaped structure, which can adapt to the positional deviation of the locking protrusion 171, ensuring the fault tolerance of the docking process and improving the reliability of the device 130. The locking protrusion 171 can be made of rigid material and have a wear-resistant surface design, extending its service life and reducing the maintenance cost of frequent replacements. In addition, the connection is made by snap-fit, eliminating the need for additional operating tools, further simplifying the loading and unloading process and improving work efficiency. At the same time, the material frame mounting plate 170 can be provided with multiple limiting grooves 151, which can be evenly or symmetrically distributed to ensure that the material frame 150 is subjected to uniform force during movement, avoiding deformation or damage caused by unilateral force, and further improving the safety and reliability of the system.

[0070] In one embodiment, such as Figure 5 As shown, the pipe conveying device 2 includes a material pick-and-place trolley 230 located at the bottom of the storage tower 110, a feeding component 210 and a discharging component 220 respectively located at both ends of the material pick-and-place trolley 230, the material pick-and-place trolley 230 includes a ground rail 231, and the feeding component 210 and the discharging component 220 are provided with guide wheels 211 that are slidably connected to the ground rail 231.

[0071] This application's solution achieves physical isolation between the feeding component 210 and the unloading component 220 by separating them at opposite ends of the material handling trolley 230, thus avoiding functional conflicts and equipment interference. The design of the ground rail 231 and guide wheels 211 not only ensures smooth movement of the trolley but also reduces running resistance and energy consumption. The modular structure of the trolley allows for adjustments to its length or load-bearing capacity according to actual needs; for example, the load capacity can be increased by increasing the number of guide wheels 211 or widening the ground rail 231. Furthermore, this partitioned design allows feeding and unloading to be performed separately in conjunction with the operation of other components, significantly improving the overall efficiency of the system, and is particularly suitable for scenarios where multiple pipe cutting machines 4 operate collaboratively, similar to the solution in this application.

[0072] Specifically, the bottom of the storage tower 110 is provided with clearance space to accommodate the material handling trolley 230, which helps to shorten the travel distance during the replenishment and unloading processes and further improves efficiency. The replenishment component 210 is located on one side of the original feeding device 3, and the unloading component 220 is located on the side closer to the feeding device 3, thus achieving reasonable partitioning. Multiple sets of ground rails 231 can be set to further improve the movement stability of the replenishment component 210 and the unloading component 220.

[0073] Understandably, the end of the material handling trolley 230 extends beyond the projection range of the storage tower 110 to ensure that the material docking between the feeding component 210 and the forklift and the material docking between the unloading component 220 and the picking component 310 can proceed smoothly.

[0074] Furthermore, both the feeding assembly 210 and the unloading assembly 220 include a support 212 for receiving the material frame 150. The support 212 is provided with a third drive assembly 213 that is connected to the guide wheel 211 for transmission. The third drive assembly 213 includes a third drive motor 2131. The output end of the third drive motor 2131 is connected to a third synchronous shaft 2132, and the third synchronous shaft 2132 is connected to the guide wheel 211.

[0075] The drive mechanism of this application achieves efficient transmission of the guide wheel 211 through the cooperation of the third drive motor 2131 and the third synchronous shaft 2132. It features fast response speed and high positioning accuracy, making it suitable for operations requiring frequent start-stop cycles. The rigid structure design of the bracket 212 enhances overall stability and prevents deformation or vibration caused by uneven load. The direct connection between the third synchronous shaft 2132 and the guide wheel 211 reduces intermediate transmission links, lowering energy loss and failure rate. Furthermore, the second and third drive motors 2131 can be equipped with encoders or sensors to achieve speed adjustment and position feedback, further improving control accuracy.

[0076] Furthermore, in this scheme, the third synchronous shaft 2132 extends to both sides of the third drive motor 2131. Since multiple ground rails 231 are provided, multiple sets of guide wheels 211 can be adapted to be provided. Each set of guide wheels 211 is connected to the third synchronous shaft 2132, which helps to improve the synchronicity of the movement of the guide wheels 211 and avoids the transmission distance of the guide wheel 211 at one end being too far.

[0077] like Figure 6 As shown, further, multiple sets of guide wheels 211 are provided along the axial direction of the bracket 212. The bracket 212 is provided with a limiting seat 240 connecting the guide wheels 211 of the same set. The pipe conveying device 2 also includes a limiting mechanism 241 movably connected to the material handling trolley 230. The limiting mechanism 241 includes a first connecting seat 2411 fixed to the limiting seat 240 and a second connecting seat 2412 fixed to the ground rail 231. The bracket 212 is provided with multiple reinforcing plates 2121. The limiting mechanism 241 includes a cylinder 2413 fixed to the reinforcing plate 2121. The first connecting seat 2411 is provided with a swing arm 2414 connected to the cylinder 2413. The second connecting seat 2412 is provided with a limiting gap 2415 that engages with the swing arm 2414.

[0078] This application's solution significantly improves the trolley's load-bearing capacity and operational stability through the distributed design of multiple sets of guide wheels 211 and limit seats 240. The cylinder 2413 of the limit mechanism 241 drives the swing arm 2414 to engage with the connecting seat, achieving rapid locking and unlocking of the trolley with short response time and high reliability. The swing arm 2414 has an arc-shaped movement path, moving with the extension and retraction of the cylinder 2413. When it engages with the second connecting seat 2412, since the second connecting seat 2412 is fixed to the ground rail 231, the first connecting seat 2411, located on the bracket 212 and connected to the swing arm 2414, cannot continue to move along the ground rail 231. Furthermore, in this application, the cylinder 2413 can be further equipped with a pressure sensor to monitor the locking status in real time, avoiding safety hazards caused by incomplete locking. Furthermore, it can be adapted to different specifications of ground rails 231 by adjusting the stroke of cylinder 2413 or the length of swing arm 2414 according to actual production needs, thus having strong versatility.

[0079] Meanwhile, limiting mechanisms 241 are installed at the ground rails 231 at both ends of the bracket 212 to ensure the overall limiting stability and reliability of the bracket 212.

[0080] In addition, to improve the stability of the bracket 212, multiple reinforcing plates 2121 are provided at intervals on the bracket 212, and the reinforcing plates 2121 are provided with openings through which the third synchronous shaft 2132 passes, thereby supporting and limiting the third synchronous shaft 2132.

[0081] In one embodiment, such as Figure 1 and Figure 7 As shown, the material handling assembly 310 includes a robotic arm 311, which is equipped with a material handling fork 312. The material handling fork 312 is inserted from both sides of the tube to the bottom of the tube to remove the tube from the material frame 150.

[0082] The robotic arm 311 of this application achieves stable gripping of the pipe through the double-sided insertion design of the picking forks 312, avoiding tilting or falling off caused by unilateral force. The width and spacing of the picking forks 312 can be flexibly adjusted according to the pipe diameter to adapt to the handling needs of pipes of different specifications. The joint structure design of the robotic arm 311 gives it high flexibility and range of motion, enabling precise positioning of the pipe within the material frame 150.

[0083] It should be noted that in actual use, the fork 312 only removes the pipe from the material frame 150, without removing the material frame 150 itself, so that the pipe can be quickly placed at the pipe cutter 4 for processing.

[0084] Furthermore, the transfer assembly 320 includes a truss 321, with the pipe cutter 4 positioned below the truss 321. The robotic arm 311 moves along the truss 321 between the unloading assembly 220 and the pipe cutter 4 to transfer the pipe to the pipe cutter 4.

[0085] This application solution utilizes a truss 321 to support the movement of the robotic arm 311, achieving efficient transfer of pipes between multiple pipe cutting machines 4. The rigid structure and lightweight design of the truss 321 ensure load-bearing capacity while reducing the impact of its own weight on system energy consumption. The robotic arm 311 can be programmably controlled along the movement path of the truss 321, supporting linear, curved, or combined movements to adapt to complex production layout requirements. Furthermore, the height and span of the truss 321 can be flexibly adjusted according to the actual workshop space, for example, by adding supports or extending the reinforcing plate 2121 to expand the coverage area. This design not only enhances the system's flexible production capabilities but also optimizes space utilization, making it particularly suitable for production scenarios involving multi-machine collaboration and high-density layouts.

[0086] In this embodiment, the truss 321 is equipped with a motor 322 and a belt assembly 323 connected to the motor 322 for transmission. The other end of the belt assembly 323 is fixed to the robotic arm 311 to enable the robotic arm 311 to move vertically, allowing it to reach or leave the material picking position. Simultaneously, the truss 321 is also equipped with a transverse drive mechanism 324 to drive a crossbeam 325 connected to the upper end of the robotic arm 311 to move along the truss 321, enabling the robotic arm 311 to reach different pipe cutting machines 4. The robotic arm 311 can place a portion of the pipe at the pipe cutting machine 4 and move to other pipe cutting machines 4 as needed to continue placing pipes. It can also move to the pipe cutting machine 4 to retrieve unprocessed pipes and return them to the unloading assembly 220, where they are placed back into the pipe placement rack 120, achieving efficient and orderly management of the pipes. The specific configuration of the truss 321 and the transverse drive mechanism 324 can be achieved using existing technology and will not be elaborated here.

[0087] In addition, the pipe rack 120 of this application can be set with more columns according to actual application needs, and the distribution of pipe storage positions can store pipes with higher application requirements in the lower placement position 121, which is conducive to further improving the loading and unloading efficiency.

[0090] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
