Description

Technical Field

[0001] This invention relates to the field of marine profile sorting technology, and in particular to an automatic marine profile sorting device and sorting method. Background Technology

[0002] With the increasing size and sophistication of ships, the types and specifications of marine profiles are becoming increasingly complex. Traditional manual sorting methods can no longer meet the efficiency, precision, and quality requirements of the modern shipbuilding industry. Shipbuilding requires the use of a large number of profiles of different specifications. Traditional manual sorting is inefficient, has a high error rate, and is labor-intensive, easily leading to sorting errors or omissions, affecting subsequent processing and assembly efficiency. Modern shipbuilding is trending towards automated and intelligent production, requiring profile sorting systems to seamlessly integrate with cutting, conveying, and storage processes to improve overall production efficiency. Although many shipyards have implemented some human-machine interactive automated equipment, this equipment can only perform simple conveying and sorting, and cannot intelligently judge based on parameters such as profile deformation, weight, and dimensions, resulting in defective products being mixed with qualified products. Existing equipment also cannot automatically adjust sorting strategies according to the needs of subsequent processes, still requiring manual intervention, affecting the continuity and stability of the production line.

[0003] Therefore, it is essential to design and develop an intelligent and flexible automated sorting device and method for marine profiles to meet the high-quality and high-efficiency production needs of the shipbuilding industry. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic sorting device and method for marine profiles, which realizes automatic and flexible sorting of traditional profiles with low manual intervention, and greatly improves sorting efficiency and sorting accuracy.

The scanning mechanism spans the rear end of the sorting front-end power roller conveyor in the left-right direction. The conveying limit mechanism, the bidirectional push rod mechanism, and the damping limit mechanism are all connected to the sorting conveyor power platform and realize XYZ direction limit. The profile storage hopper is placed on the ground and is located outside the sorting conveyor power platform. The sorting front-end power roller conveyor includes a jig body, a first drive motor, a drive roller conveyor, a three-sprocket and a first positioning sensor. The three-sprocket is driven by a drive chain. The drive motor adjusts the tension of the three-sprocket by adjusting screws. The first positioning sensor is located on the rear side of the jig body and is used to detect the incoming material status. The blocking lever mechanism includes a cylinder mounting base, a lever cylinder, a connecting shaft connecting arm, and a blocking arm. The lever cylinder is mounted on the cylinder mounting base. One end of the connecting arm is sleeved on the cylinder rod of the lever cylinder, and the other end of the connecting arm is sleeved on the connecting shaft. The blocking arm is evenly arranged along the length of the connecting shaft and is used for limiting and releasing the material feeding from both sides of the profile. The scanning mechanism includes a U-shaped bracket, a dynamic barcode scanner, and a miniature camera. The dynamic barcode scanner and the miniature camera are installed on the upper end of the U-shaped bracket and are used to capture the QR code of the profile, print character information, and feed it back to the host computer. The sorting and conveying power platform includes a platform frame, a second drive motor, a galvanized roller conveyor, and a second positioning sensor. The second drive motor drives the galvanized roller conveyor to convey the profiles, and the second positioning sensor detects the incoming material status of the profiles. The conveying limiting mechanism includes a limiting bracket, a lifting cylinder, a lifting shaft, and a stop block. The limiting bracket and the stop block both span the galvanizing roller conveyor in the left-right direction. The lifting cylinder is fixed to the lower end of the limiting bracket. The cylinder shaft of the lifting cylinder is connected to the lower end of the stop block through a floating joint. The stop block is movably connected to the limiting bracket through the lifting shaft. The bidirectional push rod mechanism includes a pusher bracket, a pusher cylinder, a linear slider, and a push rod main frame. The pusher bracket is fixed to one side of the platform frame, the pusher cylinder is fixed to the platform frame, the linear slider is slidably connected to the pusher bracket, and the push rod main frame is fixed directly above the pusher bracket. The damping limiting mechanism includes a connecting block, a spring damping hinge, and a blocking plate. The connecting block is installed on the other side of the platform frame, and the blocking plate is connected to the connecting block through the spring damping hinge. The spring damping hinge can achieve a 90° rotation.

[0006] Furthermore, the sorting front-end power roller conveyor, the blocking lever mechanism, and the sorting conveyor power platform are fixed to the ground pre-embedded plate by adjusting the foot cups.

[0007] Furthermore, the sorting front-end power roller conveyor includes a roller conveyor mounting base, which is fixed on the left and right sides of the jig body, and the drive roller conveyor is mounted on the jig body through the roller conveyor mounting base.

[0008] Furthermore, a first motor protective cover is provided on the outside of the first drive motor, and a second motor protective cover is provided on the outside of the second drive motor.

[0009] Furthermore, several of the connecting shafts are connected as a single unit by a coupling.

[0010] Furthermore, mounting flanges are fixedly provided at both the upper and lower ends of the limiting bracket, and the lifting shaft and the mounting flange cooperate to penetrate the limiting bracket vertically.

[0011] Furthermore, the push rod main frame includes a push rod web and a bottom panel. The push rod web is height-adjustable by adjusting bolts, and the bottom panel is fixed to the push rod main frame by screws.

[0012] An automatic sorting method for marine profiles using the aforementioned automatic sorting system includes the following steps: Step S1) When the sorted profiles reach both sides of the power roller conveyor at the front end of the sorting process, the blocking lever mechanism limits the profiles. Step S2) After the feeding sensor receives the signal, the blocking lever mechanism rotates the blocking swing arm, and the conveying mechanism transports the profiles on both sides to the power roller conveyor at the front end of the sorting. Step S3) The front-end power roller conveyor starts to transport profiles. After the first positioning sensor receives the information, the scanning mechanism performs dynamic scanning and character information reading on the profiles, and the information is transmitted to the host computer for processing. Step S4) The profile is conveyed to the sorting power platform. After the second positioning sensor receives the information, the drive roller and galvanizing roller stop working. Step S5) After the host computer processes the information, it sends an instruction to the control system. The bidirectional push rod mechanism is activated to push the profile into the designated profile storage hopper. Step S6) Repeat steps S1 to S5 for subsequent profiles to complete automatic material distribution; When the flow direction of the current profile storage hopper changes, the control system will move the profile to the new profile storage hopper based on the information feedback read.

[0013] Furthermore, the feeding interval T on both sides of the sorting front-end power roller conveyor satisfies: T = max{Tx, Ty} Where Tx = (Lx / 2 + L) / V, Ty = (Ly / 2 + L) / V, Tx is the left-side feeding time, Lx is the left-side material width, Ty is the right-side feeding time, Ly is the right-side material width, V is the feeding speed, and T is the rotation speed of the lever cylinder.

[0014] Furthermore, the feeding interval Ti of the bidirectional push rod mechanism (06) satisfies: Ti = Tq + LA / VG + Lz / VT + KT Where Tq is the delay time set by the sensor, LA is the length of the profile collected by the hopper, VG is the conveying speed of the conveyor rollers, LZ is the distance between the outer edge of the profile and the hopper, VT is the pushing speed of the cylinder, and KT is the allowable safety time.

[0015] This invention enables intelligent sorting without human intervention, significantly improving sorting efficiency and accuracy, reducing production and processing costs, and the sorting device has a simple structure and low maintenance costs. The automatic sorting device of the present invention can realize bidirectional feeding, effectively improving the sorting cycle of the production line; the design of the blocking lever mechanism can realize the horizontal positioning of the profile, ensuring the accuracy and efficiency of subsequent sorting; This invention achieves precise classification of profiles by using a scanning mechanism equipped with a scanning device and a camera. It can record relevant information of incoming materials and trace the relevant information of incoming materials in the previous stage of the profile, so as to achieve one item, one code and one flow direction. At the same time, the information of the scanned code and the characters, flow direction and other relevant information on the surface of the profile complement each other, which can ensure the sorting accuracy of the profiles. The conveying limiting mechanism and damping limiting mechanism of the present invention can realize the positioning of the profile in the X and Y directions, which can not only ensure the effective movement of the profile on the conveying roller, but also ensure that the material hoppers do not overlap due to the length of the profile, thus avoiding risks and providing strong protection for the subsequent material flow to the hoisting. The device and method of the present invention can ensure the orderly progress of each process, can simultaneously realize the conveying of profiles of different specifications, lengths and types, and can realize the automated sorting of multiple hoppers, reducing the operating cost of the equipment and having broad application prospects.

[0018] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] An automatic sorting device for marine profiles, such as Figure 1 As shown, it includes a sorting front-end power roller conveyor 1, a blocking lever mechanism 2, a scanning mechanism 3, a sorting conveyor power platform 4, a conveying limit mechanism 5, a bidirectional push rod mechanism 6, a damping limit mechanism 7, and a profile storage hopper 8.

[0020] The sorting front-end power roller conveyor 1, the blocking lever mechanism 2, and the sorting conveyor power platform 4 are all fixed to the ground pre-embedded plate by adjusting the feet. The overall height and level can be adjusted by adjusting the bolts on the feet. The scanning mechanism 3 is connected to the sorting front-end power roller conveyor 1 by screws, and the installation height is adjustable. The conveying limit mechanism 5, the bidirectional push rod mechanism 6, and the damping limit mechanism 7 are connected to the sorting conveyor power platform 4 by screws to achieve limit in the XYZ direction.

[0021] like Figure 2 and Figure 3 As shown, the sorting front-end power roller conveyor 1 includes a first adjusting foot cup 101, a jig body 102, a first drive motor 103, an adjusting screw 104, a first motor protective cover 105, a drive roller conveyor 106, a roller conveyor mounting base 107, a drive chain 108, a three-sprocket 109, a first positioning sensor 110, a front-end small roller conveyor 111, a first bearing seat 112, and a protective cover 113.

[0022] The first adjusting foot cup 101 is machined from Q235B steel, with milled edges on the sides for easy adjustment; the platform frame body 102 is welded from 8×100×120mm hollow rectangular square steel, with multiple reinforcing ribs in the middle to ensure the overall strength of the platform, and is fixed to the first adjusting foot cup 101 and the embedded plate by bolts; the motor drive mechanism 103 is connected to the frame body 102 by screws, and the tension of the drive main sprocket and the three sprockets 109 is adjusted by adjusting screws 104 to ensure the smooth and orderly conveying movement of the mechanism; the first motor protective cover 105 is formed by bending 4mm and serves to protect the motor drive mechanism.

[0023] Both the drive roller conveyor 106 and the front small roller conveyor 111 are made of 45 steel and galvanized to reduce friction and improve service life; the roller conveyor mounting base 107 is connected to the jig body 102 by screws and provides a rotating carrier for the drive roller conveyor 106; the three sprockets 109 are fixed to the jig body 102 by screws and realize the one-to-one connection of the drive chains 108 to drive all sprockets to rotate; the first positioning sensor 110 is fixed to the jig body 102 by screws to detect the incoming material status of the profile; the first bearing seat 112 and the protective cover 113 are connected to the jig body 102 by screws.

[0024] like Figure 4 As shown, the blocking lever mechanism 2 includes a second adjusting foot cup 201, a cylinder mounting main seat 202, a lever cylinder 203, a connecting shaft 204, a coupling 205, a connecting swing arm 206, and a blocking swing arm 207. The second adjusting foot cup 201 is connected to the embedded plate and is used to level and raise the blocking lever mechanism 2. The cylinder mounting main seat 202 is welded from hollow rectangular square steel (6×100×100mm) and connected to the second adjusting foot cup 201 with screws. The lever cylinder 203, the connecting swing arm 206, and the blocking swing arm 207 are initially locked and positioned with screws, and then welded and fixed after on-site adjustment to increase strength. The connecting shaft 204 is machined from a 35mm tempered and polished optical shaft and is connected to the coupling 205.

[0025] The design of the front-end power roller conveyor 1 and the blocking lever mechanism 2 enables the feeding of profiles from both sides. The interval T between the two-side feeding must meet the following requirements: T = max{Tx, Ty} Where Tx = (Lx / 2 + L) / V, Ty = (Ly / 2 + L) / V, Tx is the left-side feeding time, Lx is the left-side material width, Ty is the right-side feeding time, Ly is the right-side material width, V is the feeding speed, and T is the rotation speed of the lever cylinder.

[0026] like Figure 5 As shown, the scanning mechanism 3 includes a U-shaped bracket 301, an angle iron 302, a connecting plate 303, a fixed bracket 304, a dynamic barcode scanner 305, and a miniature camera 306. The U-shaped bracket 301 is formed by three aluminum profiles vertically spliced ​​together, and its height can be adjusted according to usage requirements. The angle iron 302, the connecting plate 303, and the fixed bracket 304 are connected to the U-shaped bracket 301 by screws. The dynamic barcode scanner 305 and the miniature camera 306 are connected to the fixed bracket 304 by screws, and can capture and provide feedback on the QR codes, printed characters, and text information of the profiles.

[0027] The roller conveyor can achieve dynamic QR code and data capture at a speed of up to 60m / min, with a success rate and accuracy of 100% in scanning and capturing characters, and can meet the field of view range of up to 600mm in width.

[0028] like Figure 6 and Figure 7 As shown, the sorting and conveying power platform 4 includes a third adjusting foot cup 401, a platform frame 402, a second drive motor 403, a drive sprocket protective cover 404, a galvanized roller conveyor 405, a steel bearing seat 406, a pusher and lead-out plate 407, a second positioning sensor 408, a support plate 409, and a motor protective cover 410.

[0029] The third adjusting foot cup 401 is machined from Q235B steel, with milled edges on the sides for easy adjustment. The platform frame 402 is welded from 12# channel steel, with multiple reinforcing ribs in the middle to ensure the overall strength of the platform, and is connected to the third adjusting foot cup 401 by screws. The second drive motor 403 and the drive sprocket protective cover 404 are connected to the platform frame 402 by screws. The galvanized roller conveyor 405 is made of 45# steel with galvanization treatment and is connected to the steel bearing seat 406 by screws.

[0030] The pusher plate 407 is manufactured by 6mm welding and is designed with a 20~30° slope to ensure the orderly pushing of profiles. The second positioning sensor 408 is fixed to the platform frame 402 with screws and processes the incoming profiles and subsequent signal feedback. The support plate 409 and the motor protective cover 410 are both made of Q235B bent and fixed to the platform frame 402 with screws, serving to support the pusher plate 407 and protect the second drive motor 403.

[0031] like Figure 8 As shown, the conveying limiting mechanism 5 includes a limiting bracket 501, a lifting cylinder 502, a floating joint 503, a lifting shaft 504, a stop block 505, and a mounting flange 506. The limiting bracket 501 is welded from 6×100×100mm hollow rectangular square steel. The lifting cylinder 502 and the mounting flange 506 are fixed to the limiting bracket 501 with screws. The floating joint 503 is fixed to the lifting cylinder 502 and plays a role in protecting the cylinder when the cylinder receives a large external lateral shear force.

[0032] The lifting shaft 504 is connected to the stop block 505 by screws. The mounting flange 506 is fixed at the upper and lower ends of the limit bracket 501. The mounting flange 506 is sleeved on the outside of the lifting shaft 504 to guide the lifting shaft 504 to pass through the limit bracket 501 vertically.

[0033] A second positioning sensor 408 is installed in front of the conveying limit mechanism 5, and a certain delay is given to the galvanizing roller conveyor 405. When the conveying limit mechanism 5 limits the profile, it will not hit the stop block 505 at a high speed, so that the profile can run smoothly and perform the pushing work.

[0034] like Figure 9 As shown, the bidirectional push rod mechanism 6 includes a pusher main frame 601, a pusher cylinder 602, a cylinder mounting support 603, a slider connecting plate 604, a linear slider 605, a push rod main frame 606, a push rod web plate 607, and a bottom panel 608. The pusher main frame 601 is welded from hollow rectangular square steel 4×60×80mm, with multiple reinforcing ribs in the middle to ensure the strength of the overall platform, and is fixed to the platform frame 402 with bolts.

[0035] The pusher cylinder 602 is connected to the cylinder mounting bracket 603 by screws and to the platform frame 402 by bolts; the linear slider 605 is fixed on the slider connecting plate 604 and fixed to the pusher main frame 601 by screws; the pusher main frame 606 is welded from No. 5 channel steel, with multiple reinforcing ribs in the middle to ensure the strength of the overall platform, and is fixed to the pusher main frame 601 by bolts.

[0036] like Figure 1 As shown, the bidirectional push rod mechanism 6 realizes bidirectional pushing operation through the zero position and the first position of the pushing cylinder 602. After the short material is scanned and the information is read, it is determined to enter the feeding hopper. If it enters the A or C hopper, the bidirectional push rod mechanism 6 moves to the B and D hopper positions, and vice versa.

[0037] The push rod web 607 is formed by bending Q235B steel. The height is adjusted by tightening and pushing with screws. The bottom panel 608 is fixed to the push rod main frame 606 with screws to prevent jamming caused by plate deformation when pushing materials on both sides.

[0038] like Figure 10 As shown, the damping limiting mechanism 7 includes a connecting block 701, a spring damping hinge 702, and a blocking plate 703. The connecting block 702 and the blocking plate 703 are connected to the spring damping hinge 702 by screws. The spring damping hinge 702 consists of a main plate, a web plate, a spring, and a damper. It can only achieve a 0~90° rotation, which protects the profile from lateral displacement in the horizontal direction and provides support when pushing the material.

[0039] The damping limit mechanism 7 is installed on both sides of the sorting and conveying power platform 4, such as... Figure 11As shown, the baffle plate 703 can only move between 90° and 180°. Under normal circumstances, the damping hinge is at the 90° position. When the bidirectional push rod mechanism 7 pushes the material, it is at the 180° position after being subjected to external force, allowing the short material to pass through and be fed into the hopper. When the bidirectional push rod mechanism 6 returns, due to the spring damping hinge 702, the damping limit mechanism can return to the 90° position, playing a limiting role in the short material conveying process. The design of the damping limit mechanism 7 can not only realize the profile correction function, but also save a drive mechanism, reducing the design, debugging and maintenance costs.

[0040] The profile storage hopper 8 is welded from channel steel and flat iron, serving as a profile storage unit. The sorting and conveying power platform 4 is designed with a size of 6500mm, which can accommodate the placement and collection of four 3000mm collection hoppers. A bidirectional push rod mechanism 6 is set every 3000mm. Initially, it is on the other side of the push rod. When the profile is in place, the push action is performed. The feeding interval Ti between the two push rods must satisfy the following formula: Ti = Tq + LA / VG + Lz / VT + KT Where Tq is the delay time set by the sensor, LA is the length of the profile collected by the hopper, VG is the conveying speed of the conveyor rollers, LZ is the distance between the outer edge of the profile and the hopper, VT is the pushing speed of the cylinder, and KT is the allowable safety time.

[0041] This embodiment discloses an automatic sorting method for marine profiles, such as... Figure 12 As shown, the specific workflow is as follows: Step S1) When the sorted profiles arrive at both sides of the front-end power roller conveyor 1, the blocking lever mechanism 2 limits the profiles; Step S2) After the feeding sensor receives the signal, the blocking lever mechanism 2 rotates the blocking swing arm 207, and the conveying mechanism transports the profiles on both sides to the front power roller conveyor 1 of the sorting. Step S3) The front-end power roller conveyor 1 starts to convey profiles. After the first positioning sensor 110 receives the information, the scanning mechanism 3 performs dynamic scanning and character information reading on the profiles and transmits the information to the host computer for processing. Step S4) The profile is conveyed to the sorting power platform 4. After the second positioning sensor 408 receives the information, the drive roller 106 and the galvanized roller 405 stop working. Step S5) After the host computer processes the information, it sends an instruction to the control system. The bidirectional push rod mechanism 6 is activated to push the profile into the designated profile storage hopper 8. Step S6) Repeat steps S1 to S5 for subsequent profiles to complete automatic material distribution; When the flow direction of the current profile storage hopper 8 changes, the control system will change the profile to the new profile storage hopper 8 based on the information feedback read.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
