Detailed implementation manners

[0024] The present utility model provides an automatic pipe loading rack. To make the objectives, technical solutions and effects of the present utility model clearer and more definite, the following further elaborates the present utility model with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present utility model and are not used to limit the protection scope of the present utility model.

[0025] In this article, "front" is the pipe conveying direction, and "rear" is opposite to the "front" direction.

[0026] Please refer to Figures 1-5, the present utility model provides an automatic pipe loading rack, which includes at least three sets of spaced-apart rack modules 1. Each rack module 1 includes a base frame 11, a corner frame 12 arranged on the base frame 11, a material distribution station 13 arranged at the top corner of the corner frame 12, a first material blocking assembly 2 for intercepting and releasing pipes at the material distribution station 13, a material distribution assembly 3 for screening out single pipes from multiple pipes at the material distribution station 13, and a material library pulling and feeding assembly 4 for serving as a pipe material library and pulling multiple pipes to the material distribution station 13. An introduction inclined bar 14 for guiding the pipes to slide into the material distribution station 13 and a lead-out inclined shaft 15 for guiding the pipes at the material distribution station 13 to slide forward are arranged on the corner frame 12. A to-be-fed station 53 is arranged at the tail end of the lead-out inclined shaft 15, and the to-be-fed station 53 intercepts and releases pipes through a second material blocking assembly 5. An upper loading station 82 is arranged downstream of the to-be-fed station 53, and the upper loading station 82 intercepts the sliding pipes through a positioning stop block 81. The material distribution assembly 3 includes a pushing slide plate 31 slidably arranged on the corner frame 12, a pushing driving mechanism 32 for driving the pushing slide plate 31 to move, a lifting slide plate 33 slidably arranged on the pushing slide plate 31, a lifting driving mechanism 34 for driving the lifting slide plate 33 to lift and lower, a pushing bar 35 arranged on the end face of the lifting slide plate 33 facing the material distribution station 13, a stacking pushing block 36 slidably arranged on the lifting slide plate 33, and a pushing and stacking driving mechanism 37 for driving the stacking pushing block 36 to move.

[0027] In practical applications, a laser pipe cutting machine is arranged in front of the automatic pipe loading rack provided by the present invention. Taking the case where there are three sets of rack modules 1 as an example, the staff stores a certain number of small pipes in the material storage area 41 of the material library pulling and feeding assembly 4. The pulling belt 42 of the material library pulling and feeding assembly 4 of the leftmost rack module 1 supports the pipes, the pulling belt 42 of the material library pulling and feeding assembly 4 of the middle rack module 1 supports the middle part of the pipes, and the pulling belt 42 of the material library pulling and feeding assembly 4 of the rightmost rack module 1 supports the right end of the pipes. With the support of the three contact points, the pipes can be ensured to be straight and the middle part of the pipes does not sink. When the pulling belt 42 is wound up, the pulling belt 42 will drive the pipes in the material storage area 41 to rise, and under the guiding action of the introduction inclined bar 14, multiple pipes will pour into the material distribution station 13 and fall onto the lead-out inclined shaft 15, and this part of the pipes will be temporarily stored at the material distribution station 13 under the interception of the first material blocking assembly 2. It can be understood that at this time, the pipes at the material distribution station 13 are irregularly arranged front and back and stacked up and down under the action of gravity.

[0028] Then, the material sorting component 3 screens this part of the pipe materials. Specifically, the material sorting component 3 is located downstream of the material sorting station 13. The lifting drive mechanism 34 drives the lifting slide plate 33 to rise, making the pushing bar 35 and the stacking pushing block 36 higher than the export inclined shaft 15. Then, the pushing drive mechanism 32 pushes the pushing slide plate 31 towards the material sorting station 13. Thus, the pushing bar 35 drives multiple pipe materials to move backward, and further pushes the pipe materials ranked behind away from the export inclined shaft 15 and back into the material storage area 41. The pipe material ranked at the front (i.e., close to the pushing bar 35) remains on the material sorting station 13. Then, the stacking pushing drive mechanism 37 drives the stacking pushing block 36 to extend backward. If there is a stacking situation at the material sorting station 13 at this time, the stacking pushing block 36 will push the stacked pipe materials into the material storage area 41. Therefore, after being screened by the material sorting component 3, only one pipe material to be processed remains at the material sorting station 13 in the end.

[0029] The lifting drive mechanism 34 drives the lifting slide plate 33 to descend and reset. As the pushing bar 35 and the stacking pushing block 36 descend and withdraw, the pipe material to be processed will move downward along the smooth export inclined shaft 15 under the action of gravity to the first material blocking component 2. Then, the first material blocking component 2 releases the pipe material, and the pipe material slides forward to the material feeding station 53 and is intercepted by the second material blocking component 5. When the laser pipe cutting machine can feed and process materials, the second material blocking component 5 will release the pipe material, enabling the pipe material to continue to slide forward to the loading station 82. The laser pipe cutting machine lifts and clamps the pipe material to achieve pipe cutting processing.

[0030] Compared with the prior art, the automatic pipe loading rack provided by the present invention forms an open material sorting station 13 through the cooperation of the export inclined shaft 15 and the first material blocking component 2. The material storage and feeding component 4 only needs to pull multiple pipe materials to the material sorting station 13. The pushing bar 35 and the stacking pushing block 36 of the material sorting component 3 work together to accurately screen out a single pipe material from the multiple irregularly placed pipe materials at the material sorting station 13, and the excess pipe materials fall back into the material storage area 41. This fundamentally solves the material jamming problem caused by the need to regularly arrange pipe materials in the traditional pipe loading rack, ensuring the smooth process of the whole process from pipe loading to cutting, and significantly improving the production efficiency and automation level of the laser pipe cutting machine.

[0031] In this embodiment, the export inclined shaft 15 inclines downward and is chrome-plated, so that a chrome-plated layer is formed on the export inclined shaft 15. The chrome-plated layer has the characteristics of being bright, wear-resistant, and having a high hardness, and its friction coefficient is small, especially the dry friction coefficient. Whether the pipe material is a round pipe, a square pipe, or a special-shaped pipe, it can smoothly slide and complete the transfer. The import inclined bar 14 inclines upward and is made of wear-resistant material to prevent the pipe material from rigidly rubbing against the angle frame.

[0032] Specifically, the back of the pushing slide plate 31 is provided with a first guide rail 381 with the same slope as the leading-out inclined axis 15, and the side of the angle frame 12 is fixed with a first slider 382 which is slidably connected to the first guide rail 381, thereby ensuring the linear motion of the pushing slide plate 31 when performing the pushing action, improving the stability and accuracy of the pushing process, and avoiding the position deviation of the pipe caused by the offset of the slide plate.

[0033] Furthermore, the material pushing driving mechanism 32 includes a rack 321 disposed on the material pushing slide 31 and parallel to the first guide rail 381, a first rotating shaft 322 rotatably disposed on the angle frame 12, and a gear 323 sleeved on the first rotating shaft 322, wherein the gear 323 is meshed with the rack 321. The meshing transmission mode of the rack 321 and the gear 323 is adopted to efficiently and accurately transmit the power of the material pushing driving mechanism 32 to the material pushing slide 31.

[0034] It is understandable that when the pipe on the material distribution station 13 is separated from the output inclined axis 15 and crosses the top corner of the angle frame 12, the pipe will slide back to the material storage area 41. Therefore, the active stroke of the push slide 31 determines the distance between the push strip 35 and the top corner of the angle frame 12, and the distance between the push strip 35 and the top corner is determined according to the cross-sectional size of a single pipe. Generally speaking, the distance between the push strip 35 and the top corner should be slightly larger than the width of a single pipe, ensuring the accurate separation of the pipes arranged behind during the material distribution process and avoiding the phenomenon of multiple pipes being sent out at the same time due to improper spacing. The active stroke of the push slide 31 is controlled by the travel switch assembly. During actual processing, the active stroke of the push slide 31 can be adjusted according to the type and width of the pipe, ensuring the compatibility of the equipment with pipes of various specifications and improving the scope of application and production flexibility of the automatic pipe loading rack.

[0035] The first rotating shafts 322 of two adjacent rack modules 1 are connected by a first synchronous shaft 324, and the first rotating shaft 322 of one rack module 1 is connected by a first reduction motor 325. The first rotating shafts 322 of multiple rack modules 1 can be driven by one first reduction motor 325, which greatly simplifies the design of the control system, reduces the number of required motors, and ensures the synchronization of all rack modules 1 when performing the pushing action. This high degree of coordination avoids the disorder of pipe transportation caused by asynchrony and improves the stability and efficiency of the entire loading process.

[0036] Further, a second guide rail 383 perpendicular to the export inclined shaft 15 is provided on the back surface of the lifting slide plate 33. A second slider 384 slidably connected to the second guide rail 383 is fixed to the pusher slide plate 31. The sliding fit of the second guide rail 383 and the second slider 384 ensures the precise movement of the lifting slide plate 33 in the vertical direction, avoids tilting or offset, ensures the stable lifting of the pusher bar 35 and the stacking pusher block 36, and is conducive to accurately screening the pipe materials.

[0037] In this embodiment, the lifting drive mechanism 34 includes a cylinder bracket 341 provided on the pusher slide plate 31 and a first cylinder 342 provided on the cylinder bracket 341. The end of the piston rod of the first cylinder 342 is drivingly connected to the lifting slide plate 33. The telescopic movement of the piston rod of the first cylinder 342 can quickly drive the pusher bar 35 and the stacking pusher block 36 on the lifting slide plate 33 to quickly rise or fall, improving the efficiency and control accuracy of screening the pipe materials and ensuring the smoothness of the production process.

[0038] Specifically, a third guide rail 385 with the same slope as the export inclined shaft 15 is provided on the back surface of the stacking pusher block 36. A third slider 386 slidably connected to the third guide rail 385 is fixed to the lifting slide plate 33. The design of the third guide rail 385 having the same slope as the export inclined shaft 15 ensures the linearity and stability of the stacking pusher block 36 during the pushing and stacking action, and can accurately push the stacked pipe materials back to the material storage area 41, avoiding accidental offset or jamming of the pipe materials. The stacking drive mechanism 37 includes a second cylinder 371. The cylinder body of the second cylinder 371 is hinged to the lifting slide plate 33. The end of the piston rod of the second cylinder 371 is connected to the third guide rail 385 through an adapter block 372, making the structure of the stacking drive mechanism 37 compact. The telescopic movement of the piston rod of the second cylinder 371 can drive the stacking pusher block 36 to reciprocally move towards the material distribution station 13 to push down the stacked pipe materials, so that the stacked pipe materials are finally pushed into the material storage area 41. To ensure effective screening and removal of the stacked materials, the second cylinder 371 should drive the stacking pusher block 36 to reciprocally move more than twice.

[0039] In fact, the position of the lifting slide plate 33 at its highest point directly affects the pushing height of the stacking pushing block 36, which is related to whether the stacked pipes can be pushed down. Therefore, a limiting block 343 is provided at the bottom of the lifting slide plate 33, and a limiting screw 344 is threadedly connected to the limiting block 343 and is oriented towards the bottom surface of the pushing slide plate 31. A scale 345 extending along the lifting direction of the lifting slide plate 33 is provided on the pushing slide plate 31, and a reading tip 346 cooperating with the scale 345 is provided on the lifting slide plate 33. The cooperation between the limiting screw 344 and the limiting block 343 allows the user to precisely adjust the maximum rising position of the lifting slide plate 33 according to the stacking height of the pipes, ensuring that the stacking pushing block 36 can effectively push down the stacked pipes, avoiding pushing failure caused by insufficient height. The combination of the scale 345 and the reading tip 346 provides intuitive visual feedback, and the operator can easily read the real-time position of the lifting slide plate 33, simplifying the height adjustment process and improving the operation accuracy and efficiency.

[0040] Preferably, a transition arc surface 16 and transition pulleys 17 located on both sides of the transition arc surface 16 are provided at the top of the guiding inclined bar 14. By providing the transition arc surface 16, it helps the pipes to smoothly transition from the guiding inclined bar 14 to the guiding inclined shaft 15 when flowing into the material distribution station 13, avoiding pipe jamming or scratching caused by sudden angle changes, reducing the collision and friction of the pipes during the guiding process, reducing the risk of surface damage to the pipes, and improving the integrity rate of the pipes. The transition pulleys 17 on both sides play a guiding role, helping the pipes to maintain the correct direction when entering the material distribution station 13, avoiding the pipes deviating from the track or tipping over, enhancing the stability of the pipes when entering the material distribution station 13, and conversely, also helping the pipes in the material distribution station 13 to be screened and smoothly fall back into the material storage area 41.

[0041] In this embodiment, a material storage area 41 is formed upstream of the angle bracket 12. The material storage pulling assembly 4 includes a pulling belt 42, a second rotating shaft 43 rotatably connected to the bottom frame 11, a winding wheel 44 sleeved on the second rotating shaft 43, and a transition wheel 45 rotatably connected to the angle bracket 12. One end of the pulling belt 42 is fixed to the bottom frame 11, and after winding around the transition wheel 45, the other end of the pulling belt 42 is connected to the winding wheel 44. During feeding, the winding wheel 44 winds the pulling belt 42 to lift the pipes in the material storage area 41 upwards, enabling a part of the pipes to flow into the material distribution station 13. The winding action of the winding wheel 44 can be precisely controlled. By adjusting the rotation speed and amplitude of the winding wheel 44, the tension of the pulling belt 42 can be controlled, thereby controlling the conveying speed and quantity of the pipes, improving the automation level and the controllability of the operation.

[0042] Furthermore, the second rotating shafts 43 of two adjacent rack modules 1 are connected by a second synchronous shaft 46, and the second rotating shaft 43 of one rack module 1 is connected by a second reduction motor 47. The second rotating shafts 43 of multiple rack modules 1 can be driven by a second reduction motor 47, which reduces the number of motors required, simplifies the control system, and reduces the initial investment and long-term operation cost of the equipment. The second synchronous shaft 46 ensures that the adjacent rack modules 1 are synchronized when winding the pull belt 42, making the pulling process of the pipe in the storage area 41 more stable and coordinated, and avoiding uneven force or jamming of the pipe due to asynchronism.

[0043] Specifically, the first material blocking assembly 2 includes a third cylinder 21 and a first flip baffle 22 pivotally connected to the angle frame 12, the piston rod end of the third cylinder 21 is connected to the first flip baffle 22, and the cylinder body of the third cylinder 21 is hinged to the angle frame 12; under normal working conditions, the piston rod of the third cylinder 21 is extended, and the first flip baffle 22 is in a blocking state, blocking the pipe from sliding forward. When the piston rod of the third cylinder 21 is retracted, the first flip baffle 22 is pulled from the blocking state to the avoidance state, and the action is simple and quick.

[0044] Similarly, the second material blocking assembly 5 includes a fourth cylinder 52 and a second flip baffle 51 pivotally connected to the angle bracket 12, the piston rod end of the fourth cylinder 52 is connected to the second flip baffle 51, and the cylinder body of the fourth cylinder 52 is hinged to the angle bracket 12; under normal working conditions, the piston rod of the fourth cylinder 52 is extended, and the second flip baffle 51 is in a blocking state, preventing the pipe from sliding forward. When the piston rod of the fourth cylinder 52 is retracted, the second flip baffle 51 is pulled from the blocking state to the avoidance state, and the action is simple and quick.

[0045] Preferably, the angle frame 12 is provided with a first sensor 61 for detecting whether there are pipes at the material distribution station 13 and a second sensor 62 for detecting whether there are pipes at the material feeding station 53. The first sensor 61 and the second sensor 62 are used to automatically detect whether there are pipes at the material distribution station 13 and the material feeding station 53, and feedback signals are sent to the pipe cutting control system, so that the feeding work can be carried out in an orderly manner intelligently.

[0046] In order to better regulate the position of the pipe on the rack module 1 so that the pipe can maintain balance during the sliding transmission process, a positioning reference plate 7 is provided on the outer side of the leftmost or rightmost rack module 1, and one end of the pipe can be placed against the positioning reference plate 7 to achieve positioning.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.
