Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, and in particular, to a steel pipe marking and engraving conveying system. Background Technology

[0002] Traditional seamless steel pipe production employs batch management, which suffers from difficulties in individual pipe traceability, fragmented quality data, and low logistics efficiency. Traditional batch management relies on manual records and simple barcodes, resulting in discontinuous logistics paths. Steel pipes require manual handling with tools between processes, and existing steel pipe marking technologies (such as ordinary laser marking and thermal transfer labels) suffer from issues like label detachment, deformation, or complete failure during tempering and quenching processes. High temperatures cause ink evaporation and label carbonization, making subsequent processes unable to identify steel pipe information and breaking the quality traceability chain. Furthermore, wear from flaw detection and polishing processes further accelerates the physical damage to markings, making it difficult to meet the stringent requirements of high-end manufacturing for end-to-end data traceability of individual pipes. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a steel pipe marking and engraving conveying system.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A steel pipe marking and engraving conveying system includes: a first longitudinal conveying mechanism, including a first frame and conveying rollers arranged longitudinally on the upper end of the first frame; multiple sets of the first longitudinal conveying mechanisms are arranged longitudinally, with a first support gap between adjacent first longitudinal conveying mechanisms; an alignment end plate, spaced at one end of the first longitudinal conveying mechanism, for the steel pipes on the first longitudinal conveying mechanism to abut against; a first transverse conveying mechanism, provided with a support plate that can move laterally, the first transverse conveying mechanisms are arranged longitudinally at intervals, with a second support gap between adjacent first transverse conveying mechanisms, the first transverse conveying mechanism being used to convey the steel pipes on the support plate to the marking and engraving station; a second longitudinal conveying mechanism, used to convey the steel pipes and pass them through the processing equipment; a first transfer device, having a transfer component that moves from the first support gap to lift the steel pipes on the first longitudinal conveying mechanism from the first support gap and move to the second support gap to transfer the steel pipes to the first transverse conveying mechanism; and a second transfer device, used to transfer the steel pipes on the first transverse conveying mechanism to the second longitudinal conveying mechanism.

[0006] Furthermore, the first transfer device includes a transfer frame, a lever, and a support head. The lever is movably mounted on the transfer frame, and the support head is mounted on the end of the lever. The lever can drive the support head to move into the first support gap to support the steel pipe on the first longitudinal conveying mechanism, and the lever can drive the support head to move into the second support gap to transfer the supported steel pipe to the first transverse conveying mechanism.

[0007] Furthermore, the support head is provided with a V-shaped support groove for supporting the steel pipe.

[0008] Furthermore, the bottom of the lever is rotatably mounted on the transfer frame.

[0009] Furthermore, the first transfer device includes a transfer frame, a transfer seat, a lifting cylinder, and a support rod. The transfer seat is slidably mounted on the transfer frame in a transverse direction. The lifting cylinder is mounted on the transfer seat. The lower end of the support rod is connected to the push rod of the lifting cylinder. The upper end of the support rod is provided with a support limiting groove.

[0010] Furthermore, it also includes a second transverse conveying mechanism, which is located on one side of the second longitudinal conveying mechanism and is used to receive the steel pipe and convey it to the visual inspection station.

[0011] Furthermore, the first transverse conveying mechanism includes a chain rod capable of cyclic movement, and a base plate is provided at the bottom of the support plate, the base plate being fixedly connected to the chain rod.

[0012] Furthermore, a flexible pad is installed on the alignment end plate.

[0013] Furthermore, the support plate is provided with a V-shaped groove with an opening at the top.

[0014] Furthermore, the conveying roller has a middle section and tapered sections at both ends of the middle section, the tapered sections being arranged to converge toward the middle section.

[0015] This utility model has the following beneficial effects:

[0016] The first longitudinal conveying mechanism, in conjunction with the alignment end plate, uses conveying rollers to achieve precise axial positioning of the steel pipe, providing a reference for subsequent marking and engraving. The support plate of the first transverse conveying mechanism transversely transfers the steel pipe to the marking station, ensuring consistent marking positions. The second longitudinal conveying mechanism interfaces with the processing equipment, enabling continuous flow of processes such as flaw detection, polishing, and heating, avoiding traceability interruptions caused by traditional manual handling. The transfer component of the first transfer device lifts the steel pipe from the first support gap and precisely transfers it to the first transverse conveying mechanism through the second support gap, thus avoiding structural interference and supporting the steel pipe from below, making the steel pipe transfer more stable. The first and second transfer devices realize the transfer of the steel pipe in the longitudinal-transverse-longitudinal conveying chain, improving efficiency compared to manual handling.

[0042] Please refer to Figure 1 and Figure 2 A preferred embodiment of the present invention provides a steel pipe marking and engraving conveying system, which includes a first longitudinal conveying mechanism 100, an alignment end plate 200, a first transverse conveying mechanism 300, a second longitudinal conveying mechanism 400, a first transfer device 500, and a second transfer device 600.

[0043] The first longitudinal conveying mechanism 100 includes a first frame 110 and conveying rollers 120 arranged longitudinally on the upper end of the first frame 110. A motor is mounted on the first frame 110, and the motor is connected to the conveying rollers 120 to drive them to rotate, thereby causing the steel pipes 102 on the conveying rollers 120 to move longitudinally. Specifically, the connection between the motor and the conveying rollers 120 can be achieved through gear transmission, chain transmission, or belt transmission. Multiple sets of the first longitudinal conveying mechanism 100 are arranged longitudinally, and the number of sets can be set according to the length of the steel pipes 102. Figure 4 There is a first support gap 101 between adjacent first longitudinal conveying mechanisms 100.

[0044] Alignment end plates 200 are spaced apart at one end of the first longitudinal conveying mechanism 100 for the steel pipes 102 on the first longitudinal conveying mechanism 100 to abut against. The first longitudinal conveying mechanism 100 will drive the steel pipes 102 to fit against the alignment end plates 200, and then drive the steel pipes 102 back a preset distance, thereby ensuring that the position of the steel pipes 102 on the first longitudinal conveying mechanism 100 is uniform, so that the steel pipes 102 are in the same longitudinal position after being transferred, which is convenient for subsequent fine-tuning, marking and engraving.

[0045] The first transverse conveying mechanism 300 is equipped with a support plate 310 that can move laterally. The first transverse conveying mechanisms 300 are arranged at intervals along the longitudinal direction to provide multi-position support for the steel pipe 102 and ensure the stability of the conveying of the steel pipe 102. There is a second support gap 301 between adjacent first transverse conveying mechanisms 300. The first transverse conveying mechanism 300 is used to convey the steel pipe 102 on the support plate 310 to the marking and engraving station. A multi-axis robot 900 is set on one side of the marking and engraving station. A laser marking machine 910 is installed on the movable arm of the multi-axis robot to perform laser marking and engraving on the surface of the steel pipe 102, so that text and other contents are etched on the surface of the steel pipe 102. Since the groove with a certain depth is etched on the surface of the steel pipe 102, it will not disappear due to high temperature, nor will it be worn away by wear during flaw detection and polishing, thus meeting the requirements for single-pipe process data traceability.

[0046] The second longitudinal conveying mechanism 400 is used to convey the steel pipe 102 and pass the steel pipe 102 through the processing equipment 410; the processing equipment 410 can be arranged as needed, such as sawing, straightening, heat treatment, painting, polishing, pipe end magnetic powder and other processing equipment.

[0047] The first transfer device 500 has a transfer member that moves from a first support gap 101. The transfer member can lift the steel pipe 102 on the first longitudinal conveying mechanism 100 from the first support gap 101 and can move to a second support gap 301 to transfer the steel pipe 102 to the first transverse conveying mechanism 300.

[0048] The second transfer device 600 is used to transfer the steel pipe 102 on the first transverse conveying mechanism 300 to the second longitudinal conveying mechanism 400.

[0049] This utility model provides a steel pipe marking and engraving conveying system. A first longitudinal conveying mechanism 100 cooperates with an alignment end plate 200, using conveying rollers 120 to achieve precise axial positioning of the steel pipe 102, providing a reference for subsequent marking and engraving. The support plate 310 of the first transverse conveying mechanism 300 transversely transfers the steel pipe 102 to the marking station, ensuring consistent marking positions. A second longitudinal conveying mechanism 400 connects with the process processing equipment 410, enabling continuous flow of processes such as flaw detection, polishing, and heating, avoiding traceability interruptions caused by traditional manual handling. The transfer component of the first transfer device 500 lifts the steel pipe 102 from the first support gap 101 and precisely transfers it to the first transverse conveying mechanism through the second support gap 301, thus avoiding structural interference and allowing the steel pipe 102 to be lifted from below, making the transfer of the steel pipe 102 more stable. The first transfer device 500 and the second transfer device 600 realize the transfer of the steel pipe 102 in a longitudinal-transverse-longitudinal conveying chain, improving efficiency compared to manual handling.

[0050] Reference Figure 5 and Figure 7 In some embodiments of this utility model, the first transfer device 500 includes a transfer frame 510, a lever 520, and a support head 530, with the support head 530 being the transfer component. The lever 520 is movably mounted on the transfer frame 510, and the support head 530 is mounted on the end of the lever 520. Both the lever 520 and the support head 530 can move within the first support gap 101 and the second support gap 301, thereby lifting the steel pipe 102 and placing it down into the first transverse conveying mechanism 300. The lever 520 can drive the support head 530 to move into the first support gap 101 to support the steel pipe 102 on the first longitudinal conveying mechanism 100, and the lever 520 can drive the support head 530 to move into the second support gap 301 to transfer the supported steel pipe 102 to the first transverse conveying mechanism 300, thereby realizing the transfer of the steel pipe 102 between the longitudinal and transverse conveying mechanisms.

[0051] Reference Figure 7 In a specific embodiment of this utility model, the support head 530 is provided with a V-shaped support groove 531 for supporting the steel pipe 102, so as to be adaptable to steel pipes 102 of different diameters and to provide a more stable support for the steel pipe 102.

[0052] Reference Figure 3 and Figure 7 In a specific embodiment of this utility model, the bottom of the lever 520 is rotatably mounted on the transfer frame 510, and the support head 530 is rotatably mounted on the lever 520. Figure 7As shown, the rotation of the lever 520 causes the steel pipe 102 to move, while the rotation of the support head 530 keeps the opening of the V-shaped support groove 531 facing upwards, ensuring stable posture and providing stable support for the steel pipe 102. In the initial state, the lever 520 moves to a position where the support head 530 is below the steel pipe 102 on the first longitudinal conveying mechanism 100. When the steel pipe 102 reaches directly above the support head 530, the lever 520 rotates upwards, and the support head 530 also rotates relative to the lever 520 until the lever 520 rotates downwards, thereby transferring the steel pipe 102 onto the support plate 310 of the first transverse conveying mechanism 300. Specifically, a motor can be installed on the lever 520, and the motor is connected to the support head 530 to drive the support head 530 to rotate. A rotary drive mechanism can be installed on the transfer frame 510 to drive the lever 520 to rotate. The rotary drive mechanism can be a motor or a hydraulic cylinder. The motor can be connected to the lever 520 to drive its rotation, or one end of the hydraulic cylinder can be hinged to the transfer frame 510 and the other end to the lever 520, thereby driving the lever 520 to rotate through extension and retraction. Of course, in order to increase the range of motion of the lever 520, a sliding slide can be provided on the transfer frame 510. The slide is driven to slide by the extension and retraction cylinder, and the bottom of the lever 520 is rotatably hinged to the slide, thereby expanding the range of motion of the lever 520 laterally. It is understood that in order to achieve stable support for the steel pipe 102, multiple levers 520 and support heads 530 are usually arranged longitudinally.

[0053] Reference Figure 8 In a specific embodiment of this utility model, the first transfer device 500 includes a transfer frame 510, a transfer seat 540, a lifting cylinder 550, and a support rod 560, with the support rod 560 being the transfer component. The support rod 560 can move within the first support gap 101 and the second support gap 301. The transfer seat 540 is slidably mounted laterally on the transfer frame 510. A telescopic cylinder can be mounted on the transfer frame 510, and the telescopic push rod of the telescopic cylinder is connected to the transfer seat 540, thereby driving the transfer seat 540 to slide. Alternatively, a rack can be provided on the transfer frame 510, and a motor can be mounted on the transfer seat 540. The output shaft of the motor is connected to a gear, which meshes with the rack, thereby driving the gear to rotate through the motor, causing the transfer seat 540 to move along the rack. It can be understood that a guide rail can be provided on the transfer frame 510, and a slider adapted to the guide rail is provided at the bottom of the transfer seat 540, thereby achieving sliding guidance. The lifting cylinder 550 is installed on the transfer seat 540. The lower end of the support rod 560 is connected to the push rod 551 of the lifting cylinder 550. The upper end of the support rod 560 is provided with a support limiting groove 561, thereby realizing the support of the steel pipe 102. Figure 8As shown, in the initial state, the support rod 560 is lower than the steel pipe 102 on the first longitudinal conveying mechanism 100. Then, the lifting cylinder 550 drives the support rod 560 to rise, lifting the steel pipe 102. Next, the transfer seat 540 moves horizontally until the steel pipe 102 is above the support plate 310 of the first transverse conveying mechanism 300. Then, the lifting cylinder 550 drives the support rod 560 to descend, placing the steel pipe 102 on the support plate 310. Finally, the push rod 551 continues to descend to its lowest position and returns to the initial state. It is understood that, in order to achieve stable support for the steel pipe 102, multiple transfer seats 540, lifting cylinders 550, and support rods 560 are typically arranged longitudinally.

[0054] Reference Figure 1 and Figure 5 In some embodiments of this utility model, a second transverse conveying mechanism 700 is also included. The second transverse conveying mechanism 700 is disposed on one side of the second longitudinal conveying mechanism 400 and is used to receive the steel pipe 102 and convey the steel pipe 102 to the visual inspection station. A camera 800 can be installed at the visual inspection station to perform visual inspection on the passing steel pipe 102. A third transfer device is also provided between the second transverse conveying mechanism 700 and the second longitudinal conveying mechanism 400.

[0055] It is understandable that the second longitudinal conveying mechanism 400 can also be arranged longitudinally with gaps between adjacent parts, and the second transverse conveying mechanism 700 can also be arranged longitudinally with gaps between adjacent parts. The second and third transfer devices can adopt the same structure as the first transfer device. They can adopt a structure of transfer frame 510, lever 520, and support head 530, or a structure of transfer frame 510, transfer seat 540, lifting cylinder 550, and support rod 560, which can be selected as needed. Of course, the transfer device can also use other mechanisms capable of transferring pipe fittings, such as a slide table capable of longitudinal and transverse movement and grippers mounted on the slide table.

[0056] It is understandable that a third transverse conveying mechanism is provided on the side of the first longitudinal conveying mechanism 100 opposite to the first transverse conveying mechanism, and the first transfer device can be used to feed the steel pipe 102 to the first longitudinal conveying mechanism 100.

[0057] Reference Figure 6In some embodiments of this utility model, the first transverse conveying mechanism 300 includes a chain rod 320 capable of cyclic movement, and a base plate 311 is provided at the bottom of the support plate 310, with the base plate 311 fixedly connected to the chain rod 320. Specifically, two chains are provided and longitudinally spaced apart, with both ends of the chain rod 320 connected to links on the chain. A motor and a sprocket are mounted on the frame of the first transverse conveying mechanism 300. The sprocket drives the chain rod 320 or the chain to rotate, thereby driving the chain rod 320 to cyclically move, thus moving the support plate 310 laterally. The base plate 311 and the chain rod 320 can be fixed by fasteners or welding. The second transverse conveying mechanism 700 can also have the same structural form as the first transverse conveying mechanism 300.

[0058] Reference Figure 2 In some embodiments of this utility model, a flexible pad 210 is installed on the alignment end plate 200. The flexible pad 210 may be made of rubber to avoid rigid collision between the steel pipe 102 and the alignment end plate 200.

[0059] Reference Figure 6 In some embodiments of this utility model, the support plate 310 is provided with a V-shaped groove 312 with an opening at the upper end, thereby achieving stable support for the steel pipe 102.

[0060] Reference Figure 2 In some embodiments of this utility model, the conveying roller 120 is provided with an intermediate section 121 and tapered sections 122 at both ends of the intermediate section 121. The tapered sections 122 are arranged to converge toward the intermediate section 121, so that the steel pipe 102 will stably contact the intermediate section 121 and will not detach from the contact with the intermediate section 121.

[0061] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
