Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, and in particular to a universal conveying device for multi-specification pipes. Background Technology

[0002] With the widespread application of composite pipes in construction, petroleum, and chemical industries, traditional inkjet marking and mechanical engraving methods are prone to defects such as insufficient adhesion, easy wear, and environmental pollution, and are difficult to adapt to the marking needs of pipes made of different materials. Laser marking technology, through non-contact high-energy beam processing, can form permanent, high-precision markings on the surface of various composite pipes, offering advantages such as no consumables, environmental friendliness, and corrosion resistance. Furthermore, with advancements in fiber lasers and galvanometer systems, laser marking equipment has significantly improved in marking speed, clarity, and automation, meeting the stringent requirements of product traceability and brand identification in modern industrial production.

[0003] The applicant obtained the following prior art through searching, specifically, patent CN211638687U discloses a pipe laser marking device, including a support base plate. A linear slide rail is horizontally welded to the top center of the support base plate. Two sets of support blocks are snapped onto the top of the linear slide rail, and the two sets of support blocks are symmetrically arranged about the axis of the linear slide rail. A pipe is horizontally placed on the top of the two sets of support blocks. This utility model drives the rotation of the positioning screw through a positioning motor. Through the thread action between the positioning screw and the positioning bracket, the laser marking machine can move horizontally with the rotation of the positioning screw, keeping the position of the pipe stationary. Marking is performed by moving the laser marking machine, avoiding the phenomenon of marking skew. At the same time, the position of the positioning bracket on the support column can be adjusted, and the distance between the laser marking machine and the pipe can be adjusted, so that the laser marking machine can mark pipes of different diameters, improving the applicability.

[0004] As can be seen from the patent above, although this type of pipe laser marking device can avoid the phenomenon of marking skew and can mark pipes of different diameters by adjusting the distance between the laser marking machine and the pipe, thus improving its applicability, in actual use, especially when laser marking a large number of pipes, workers need to repeatedly install and remove the pipes from the support block. This not only makes the operation cumbersome and increases the labor intensity of the workers, but also reduces the work efficiency and makes it difficult to meet the needs of continuous industrial production.

[0033] Example 1:

[0034] This utility model proposes a universal conveying device for pipes of various specifications.

[0035] In one embodiment of this utility model, a multi-specification pipe universal conveying device 100 is used to convey pipes to a laser marking machine 200. It includes a workbench 1, a placement rack 2, a push plate 3, a drive assembly 4, and an unloading assembly 5. The placement rack 2 is set on the workbench 1 and is used to store pipes. The placement rack 2 includes several placement slots. The several placement slots are inclined and each has a through slot 6 to form a conveying channel 7. The outlet of the conveying channel 7 is set opposite to the laser marking machine 200 and is movably installed with a stop bar 8. The push plate 3 is movably installed at the outlet of the conveying channel 7 through the drive assembly 4. The push plate 3 is used to pick up and convey pipes to the laser marking machine 200. The push plate 3 is provided with a stop block 9 for contacting the pipes. The unloading assembly 5 is set on the workbench 1 and is used to push the pipes on the push plate 3.

[0036] Specifically, such as Figures 1 to 6As shown, in the universal multi-specification pipe conveying device 100 of this utility model, since the placement rack 2 is set on the workbench 1, multiple pipes to be processed can be pre-stacked through several placement slots in the placement rack 2, thereby facilitating continuous feeding of the laser marking machine 200; at the same time, since the several placement slots are inclined and each has a through slot 6, a conveying channel 7 for conveying pipes can be formed on the placement rack 2, that is, the pipes on the placement rack 2 can be continuously conveyed to the push plate 3 sequentially through the conveying channel 7 under the action of gravity. The structure is ingeniously and rationally designed. Furthermore, because a stop bar 8 is movably installed at the outlet of the feeding channel 7, and this stop bar 8 can be installed using a cylinder or an electric push rod, it can move relative to the placement groove to close or open the outlet of the feeding channel 7. This ensures that the push plate 3 picks up only one pipe at a time, effectively preventing jamming caused by multiple pipes slipping simultaneously. This achieves seamless integration between the laser marking machine 200 processing steps and the feeding steps of this invention, facilitating continuous automated operation. In addition, while ensuring the pipes can pass smoothly through the through groove 6, the placement groove can be used to store pipes of different specifications and sizes. This ensures automatic and continuous feeding of over 200 specifications and sizes of pipes for the laser marking machine, making it widely applicable and highly versatile.

[0037] Understandably, when the pipe slides onto the push plate 3, the push plate 3 is movably mounted at the outlet of the conveying channel 7 via the drive assembly 4, which can be a cylinder, hydraulic cylinder, or other linear drive device. This allows the push plate 3 to move relative to the worktable 1 and push the pipe to the laser marking machine 200 to complete the marking operation. The structural design is simple and reasonable. Furthermore, since the push plate 3 is equipped with a stop 9 for contacting the pipe, the stop 9 prevents the pipe from rolling or shifting during conveying, ensuring the stability of the pipe installation on the push plate 3 and guaranteeing the precise alignment of the pipe axis with the laser marking position. In addition, after the pipe is marked, the worktable 1 is equipped with a discharge assembly 5, which can be an electric push rod, etc. The discharge assembly 5 can push the pipe away from the worktable 1, allowing the pipe to pass over the stop 9 and fall into the external collection tank or onto the conveying device for transport to the next process. It should be noted that the reciprocating motion of the push plate 3 and the opening and closing action of the stop bar 8 can be synchronized through an external control system. That is, after the current pipe is marked and pushed out by the unloading component 5, the push plate 3 can immediately reset and pick up the next pipe, thus forming an efficient marking operation cycle for multiple pipes to meet the needs of automated continuous production of pipes.

[0038] Compared with existing technologies, the universal conveying device 100 for multi-specification pipes of this utility model can form a gravity-fed conveying channel 7 through several inclined placement slots. Used in conjunction with the push plate 3, it can automatically and continuously feed pipes to the laser marking machine, simplifying the pipe marking process, improving work efficiency, and meeting the needs of automated continuous pipe production. The stop bar 8 ensures accurate conveying of single pipes on the push plate 3 and precise feeding to the laser marking machine, effectively preventing jamming caused by multiple pipes slipping simultaneously, ensuring reliable operation. The stop block 9 on the push plate 3 prevents pipes from rolling or shifting during conveying, ensuring the stability of the pipes on the push plate 3, guaranteeing precise alignment of the pipe axis with the laser marking position, improving the accuracy of pipe marking, and ensuring processing quality. The unloading component 5 allows the pipes to automatically fall into an external collection tank or onto a conveying device after marking for transport to the next process, ensuring the continuity of marking processing and a high degree of automation.

[0039] In one embodiment, a mounting hole is provided on the side wall of the worktable 1 opposite to the laser marking machine 200. The drive assembly 4 includes a drive member 10 and a connecting rod 11. The connecting rod 11 passes through the mounting hole, and its two ends are detachably connected to the push plate 3 and the power output end of the drive member 10, respectively, so that the drive member 10 can drive the push plate 3 to move closer to or away from the laser marking machine 200. Specifically, as shown... Figure 1 , Figure 2 and Figure 6 As shown, the drive component 10 can be a cylinder, hydraulic cylinder, or electric push rod, etc. Since the power output end of the drive component 10 is detachably connected to the connecting rod 11, and the other end of the connecting rod 11 is detachably connected to the push plate 3, all three detachable connections can be made by threaded connections, which facilitates disassembly and assembly and is convenient for maintenance. Furthermore, when the drive component 10 is running, the power is transmitted to the push plate 3 through the connecting rod 11, thereby enabling the push plate 3 and the tubes on it to move precisely to the laser marking machine 200. After the tubes are marked, the push plate 3 is reset to the initial position under the action of the drive component 10 to pick up the next tube. This enables automatic continuous feeding of tubes to the laser marking machine 200, and the structural design is simple and reasonable.

[0040] In one embodiment, a ramp 12 for contacting the pipe is formed on the push plate 3. The ramp 12 slopes downwards towards the direction away from the worktable 1, and the ramp 12 and the stop block 9 form a limiting space for accommodating the pipe. Specifically, as shown... Figure 1 , Figure 2 and Figure 6As shown, during the marking process, the ramp 12 formed on the push plate 3 abuts against the pipe, providing stable support and effectively preventing bending deformation due to its own weight. This ensures the processing quality of the pipe marking, and is especially suitable for marking longer pipes. Furthermore, the ramp 12, together with the stop block 9, forms a limiting space for accommodating the pipe, significantly improving the pipe's installation stability and reliability.

[0041] In one embodiment, at least two stops 9 are spaced apart on the push plate 3, and the push plate 3 has grooves for mounting the stops 9. An elastic element is provided between each stop 9 and the bottom of the groove. Specifically, as shown... Figure 1 , Figure 2 and Figure 6 As shown, multiple stops 9 spaced apart on the push plate 3 can limit the pipe's contact at multiple points, effectively preventing axial deflection during transport and ensuring the pipe's axis remains precisely aligned with the laser marking position, thus improving the marking quality. Furthermore, after the pipe is marked, the unloading assembly 5 of the push plate 3 operates, pushing the pipe away from the worktable 1. Because an elastic element (e.g., a spring) is installed between any stop 9 and the bottom of the groove, the stop 9 can retract into the groove under the action of the unloading assembly 5, allowing the pipe to fall smoothly from the push plate 3, ensuring the efficiency and continuity of the overall marking process. It is worth noting that an external collection trough or conveying device can be installed below the laser marking machine 200 to receive the pipe, allowing for quick and convenient transport to the next process.

[0042] In one embodiment, such as Figure 1 , Figure 2 and Figure 6 As shown, the push plate 3 has a notch 13. The unloading assembly 5 includes a push rod 14 and a flexible block 15. The push rod 14 is correspondingly arranged with the notch 13 and is detachably installed on the worktable 1. The flexible block 15 is located at the end of the push rod 14 away from the worktable 1 and is used to abut against the pipe. Understandably, when the marked pipe needs to be unloaded, the push plate 3 moves towards the worktable 1. At this time, the push rod 14 engages with the notch 13, allowing the flexible block 15 on the push rod 14 to abut against the pipe, pushing the pipe away from the worktable 1, ensuring effective separation of the pipe from the push plate 3, and ensuring the continuity of the automated production process. Furthermore, the flexible block 15 can be made of rubber or silicone. By abutting against the outer wall of the pipe, the flexible block 15 can effectively buffer the impact of the push rod 14 on the pipe, avoiding damage to the pipe surface.

[0043] In one embodiment, the display rack 2 further includes a plurality of uprights 16 arranged in a rectangular array. A plurality of placement slots are detachably mounted on the uprights 16 from top to bottom. These placement slots are upper placement slots 17 and lower placement slots 18, with their ends respectively approaching and moving away from each other. Specifically, as... Figure 1 , Figure 2 and Figure 5 As shown, the placement slots and columns 16 can be detachably installed by threaded connection, which facilitates the disassembly and assembly of the placement slots and makes maintenance easier. Furthermore, by bringing the ends of the upper placement slot 17 and the lower placement slot 18 closer to each other and further away from each other, the upper placement slot 17 and the lower placement slot 18 can be arranged in a "<" shape, thereby creating a height difference between the upper placement slot 17 and the lower placement slot 18. This allows the pipes to be automatically conveyed to the push plate 3 through the material conveying channel 7, ensuring the independent movement of each layer of pipes when sliding down under gravity.

[0044] In one embodiment, the bottom of the upper placement trough 17 is provided with a through groove 6, and the opposite side walls of the upper placement trough 17 are provided with sliding grooves 19. A baffle 20 for blocking the through groove 6 is movably installed within the sliding groove 19; the wall of the lower placement trough 18 is provided with a through groove 6, forming the outlet of the material conveying channel 7. Specifically, as... Figures 1 to 5 As shown, the baffle 20 can be installed in the slide 19 with bolts to limit its movement. This allows the operator to adjust the opening area of ​​the slide 19 through the baffle 20, thereby controlling the dropping of pipes of different diameters and ensuring that only a single pipe passes through the through groove 6, preventing blockage of the material conveying channel 7, and ensuring reliable use.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit 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 protection scope of this application.
