Description

Technical Field

[0001] This invention belongs to the technical field of gas cylinder storage and logistics equipment, specifically relating to an adaptive inbound and outbound delivery system for multi-specification wound gas cylinders and its working method. Background Technology

[0002] Fiber-wound gas cylinders (such as Type IV hydrogen storage cylinders and LNG cylinders) are widely used in new energy and industrial gas fields due to their lightweight and high strength. The surface of these cylinders is formed by curing fibers and resin, resulting in low hardness and susceptibility to scratches, impacts, and other mechanical damage. Damage to the surface fiber layer severely affects the safety performance and service life of the cylinder.

[0003] Currently, the mainstream production method for fiber-wound gas cylinders is palletless roller conveyor. This method offers advantages such as convenient docking with different processing sections and equipment, flexible flow between workstations, and no additional pallet costs, making it well-suited for multi-variety, variable-batch production models. However, existing technologies have the following prominent problems in the docking process from the production roller conveyor to the automated storage and retrieval system (AS / RS): 1. Traditional operation methods rely on manual forklifts or simple push-pull devices, which are inefficient and can easily cause scratches and collision damage to the surface of gas cylinders during manual operation, posing a significant safety risk.

[0004] 2. Simple automated equipment cannot automatically identify and handle multi-specification wound gas cylinders of different lengths and diameters, resulting in poor versatility. In particular, small-diameter gas cylinders are prone to getting stuck in the gaps of the roller assembly when passing through the conveyor surface with gaps, leading to conveying interruption or damage to the gas cylinder.

[0005] 3. Ordinary pick-up and drop-off mechanisms lack an effective centering and positioning process, often relying on repeated adjustments of the forks and gas cylinders, which affects storage and retrieval efficiency, and the surface is easily scratched by the movement and friction of the gas cylinders during the adjustment process.

[0006] 4. The fork extension and retraction, gas cylinder receiving, and centering functions are scattered across different workstations, resulting in a large overall space requirement and difficulty in matching the operating rhythm.

[0007] 5. The robotic arm gripping solution requires frequent replacement of grippers, and the weight of large-sized gas cylinders can reach hundreds of kilograms, resulting in high equipment procurement costs. Summary of the Invention

[0008] The purpose of this invention is to provide an adaptive inbound and outbound delivery system for multi-specification wound gas cylinders and its working method, so as to solve the problems of low docking accuracy, dispersed structure, inability to reliably adapt to cylindrical wound gas cylinders of different sizes, insufficient consideration of gas cylinder surface protection, and high cost, low efficiency and difficulty in handling both large and small cylinders with robotic arms and tooling pallets in existing devices.

[0009] The technical solution adopted by the present invention to solve the above problems includes: a multi-specification winding gas cylinder adaptive inbound and outbound conveying system, characterized in that: it includes a pushing receiving mechanism and an inbound and outbound conveying mechanism, the inbound and outbound conveying mechanism including a frame, a lifting support assembly, a lifting rotation assembly, a barcode scanning and centering assembly, and a moving trolley; the pushing receiving mechanism is set on the inbound side of the inbound and outbound conveying mechanism, the pushing receiving mechanism including a conveying roller group and a rocker arm mechanism; the rocker arm mechanism is set on the side of the conveying roller group, it includes a movable push plate, a rocker arm frame, a rocker arm drive mechanism, a rocker arm, and a pushing drive mechanism; the rocker arm frame is mounted on the pushing drive mechanism; the rocker arm is rotatably mounted on the rocker arm frame; the rocker arm drive mechanism is mounted on the rocker arm frame and connected to the rocker arm, the movable push plate is fixed on the rocker arm; the frame is arranged sequentially along the gas cylinder conveying direction with a gas cylinder receiving station, a lifting rotation barcode scanning and centering station, and an inbound docking station; the moving trolley is set on the frame and can move along the inbound and outbound conveying direction. The gas cylinder conveying system moves along the frame to the gas cylinder receiving station, the lifting and rotating barcode scanning and centering station, and the warehousing docking station. A trolley with rollers is mounted on the moving trolley. A lifting support assembly is located below the gas cylinder receiving station, comprising a lifting mechanism and a support roller assembly mounted on the lifting mechanism. A lifting and rotating assembly is located below the lifting and rotating barcode scanning and centering station, comprising a lifting mechanism, a rotating roller assembly, and a drive motor. The drive motor and rotating roller assembly are mounted on the lifting mechanism, and the drive motor is connected to the rotating roller assembly. The trolley roller assembly has a gap for the rotating roller assembly to pass through during its ascent. The barcode scanning and centering assembly is located above the lifting and rotating barcode scanning and centering station, comprising a barcode scanner, a clamping and centering push plate, a centering drive mechanism, and a force feedback module. The centering drive mechanism and barcode scanner are both mounted on the frame, the clamping and centering push plate is mounted on the centering drive mechanism, and the clamping and centering push plate has a force feedback module.

[0010] The gas cylinder receiving station of the present invention is located at the front of the frame, the lifting, rotating, scanning and centering station is located at the middle of the frame, and the warehousing docking station is located at the rear of the frame.

[0011] The rotating roller assembly of the present invention includes a passive roller assembly and an active roller assembly; both the passive roller assembly and the active roller assembly are arranged in two parallel rows, and the drive motor is connected to the active roller assembly.

[0012] The lifting mechanism and the jacking mechanism described in this invention both adopt scissor mechanisms.

[0013] The barcode scanner described in this invention faces downwards.

[0014] The clamping and centering push plates described in this invention are a pair, arranged opposite to each other.

[0015] The clamping surface of the clamping centering push plate of the present invention is covered with polyurethane or rubber soft material.

[0016] The present invention provides three gaps between the trolley roller assembly and the body of the mobile trolley, forming three insertion ports for inserting forks. The middle insertion port is adapted to a small gas cylinder, and the two insertion ports on both sides are adapted to a large gas cylinder.

[0017] A working method for an adaptive inbound and outbound delivery system for multi-specification wound gas cylinders includes the following steps: S1: The mobile trolley moves along the cylinder conveying direction on the frame to the cylinder receiving station; S2: The upstream roller conveyor transports the gas cylinders to the conveyor roller assembly; S3: The lifting mechanism raises the support roller assembly, and the support roller assembly passes through the gap of the trolley roller assembly from below, forming a temporary roller assembly with the trolley roller assembly. S4: The push drive mechanism pushes the rocker arm frame to move, the rocker arm frame drives the moving push plate to move, and the moving push plate pushes the gas cylinder on the conveying roller group to the temporary roller group; S5: The lifting support assembly descends and resets, and the weight of the gas cylinder is independently borne by the trolley roller group; S6: The mobile trolley transports the gas cylinders to the lifting, rotating, scanning, and centering station; S7: The centering drive mechanism drives the clamping centering push plate to move, forcibly constraining the gas cylinder to the preset center position, thus completing the mechanical centering; S8: The lifting mechanism is raised, and the rotating roller group passes through the gap of the trolley roller group from below, lifting the gas cylinder from the moving trolley. The drive motor group drives the rotating roller group to rotate, thereby driving the gas cylinder to rotate slowly around the vertical axis. S9: The barcode scanner continuously reads the barcode label on the surface of the gas cylinder during its rotation. Once the reading is successful, the drive motor unit immediately stops rotating. S10: The lifting and rotating assembly descends and resets, and the gas cylinder falls back onto the moving trolley; S11: The mobile trolley transports the gas cylinder to the fork docking station, where it waits for the forks to move it away.

[0018] Compared with the prior art, the present invention has the following advantages and effects: It adapts to the damage-proof docking of gas cylinders of different sizes and specifications. The height of the moving push plate can be adjusted by the rocker arm mechanism to adapt to gas cylinders of different diameters, ensuring that the force of the moving push plate always acts on the center line of the gas cylinder and avoids the situation of unbalanced force. The entire process of gas cylinder docking, positioning, and alignment is carried out by rolling, with no relative sliding between contact surfaces.

[0019] Reliable transport of small-diameter gas cylinders. The lifting support assembly fills the gap in the trolley roller assembly during connection, forming a continuous rolling surface, allowing small-diameter gas cylinders to smoothly transition to the middle of the trolley, eliminating jamming, and increasing the equipment's adaptability to gas cylinders of different sizes; Compared to existing centering and clamping structures that rely solely on stroke positioning, this solution incorporates force feedback modules on both sides of the clamping plates. By comparing the contact forces on both sides, the centering and clamping status of the workpiece is determined. This allows for adaptation to any initial placement position of the workpiece, resulting in good centering and clamping stability and strong versatility. Simultaneously, the force feedback enables control of the clamping force, effectively preventing workpiece damage or crushing caused by excessive clamping force. It also reduces the probability of hard extrusion damage caused by stroke exceeding limits, significantly improving the operational safety and overall service life of the equipment.

[0020] The efficient integration of roller conveyor to the automated warehouse docking system integrates roller conveyor, lifting and rotation with top scanning, bottle alignment, and 600-degree fork docking into the same unit, shortening the overall length of the mechanism.

[0021] With a high degree of automation, the system can automatically adjust the parameters of each mechanism according to the specifications of the gas cylinders, realizing fully automated operation from roller conveyor receiving to docking with the automated warehouse. No manual intervention is required, which reduces labor intensity and improves operational safety. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. The following embodiments are illustrative of the invention, and the invention is not limited to the following embodiments. The drive mechanism in the following embodiments may use conventional drive elements such as cylinders, electric cylinders, or motor lead screws.

[0025] The embodiments of the present invention include a pushing receiving mechanism 100 and an inbound / outbound material feeding mechanism. The inbound / outbound material feeding mechanism includes a frame 1, a lifting support assembly 200, a lifting and rotating assembly 300, a barcode scanning and centering assembly 400, and a moving trolley 500.

[0026] 1. The pushing and receiving mechanism 100 is used for conveying gas cylinders. The pushing and receiving mechanism 100 is installed on the inlet side of the inlet and outlet material receiving mechanism. The pushing and receiving mechanism 100 includes a conveying roller group 106 and a rocker arm mechanism.

[0027] The conveyor roller assembly 106 extends from the upstream, and the gas cylinder reaches the front of the movable push plate 101 on the roller assembly. The conveyor roller assembly 106 consists of two rollers with trapezoidal cross sections, coaxially mounted on a shaft with the small ends facing each other and the large ends facing outwards, forming a V-shaped working surface from the side. When carrying the gas cylinder, it generates a component force towards the center on the outer wall of the gas cylinder, causing the gas cylinder to automatically slide towards the center of the roller assembly and be limited during rolling, preventing the gas cylinder from shifting laterally or slipping during conveying.

[0028] The rocker arm mechanism is located on the side of the conveyor roller assembly 106 and includes a movable push plate 101, a rocker arm frame 102, a rocker arm drive mechanism 103, a rocker arm 104, and a push-drive mechanism 105. The rocker arm frame 102 is mounted on the push-drive mechanism 105; the rocker arm 104 is rotatably mounted on the rocker arm frame 102; the rocker arm drive mechanism 103 is mounted on the rocker arm frame 102 and connected to the rocker arm 104; the movable push plate 101 is fixed to the rocker arm 104; and the rocker arm drive mechanism 103 drives the rocker arm 104 to swing up and down, thereby adjusting the height of the movable push plate 101 so that the working surface of the movable push plate 101 is always aligned with the center height of gas cylinders of different diameters. In this embodiment, the rocker arm drive mechanism 103 uses a cylinder, and the push-drive mechanism 105 uses a linear module. The working surface of the movable push plate 101 is covered with polyurethane or rubber soft material, and the working surface of the movable push plate 101 matches the surfaces of both ends of the gas cylinder, increasing the contact area, reducing the pressure per unit area, and avoiding excessive local pressure that could damage the surface of the gas cylinder.

[0029] Upon receiving the signal, the push drive mechanism 105 pushes the rocker arm frame 102 to move. The rocker arm frame 102 then drives the movable push plate 101 to move, pushing the gas cylinder on the conveying roller assembly 106 toward the moving trolley 500. The movable push plate 101 can be flexibly adjusted in height by the rocker arm 104. For example, when pushing a large-diameter gas cylinder, the rocker arm drive mechanism 103 drives the rocker arm 104 to rotate upward, raising the movable push plate 101. When pushing a small-diameter gas cylinder, the rocker arm drive mechanism 103 drives the rocker arm 104 to rotate downward, lowering the movable push plate 101, so that the working surface of the movable push plate 101 is in good contact with the bottom of the gas cylinder.

[0030] Along the direction of cylinder conveying, the frame 1 is equipped with a cylinder receiving station, a lifting, rotating, scanning and centering station, and a warehousing docking station. The cylinder receiving station is located at the front of the frame 1, the lifting, rotating, scanning and centering station is located in the middle of the frame 1, and the warehousing docking station is located at the rear of the frame 1.

[0031] The mobile trolley 500 is movably mounted on the frame 1 via a bottom slider guide rail and a drive mechanism. It can move along the cylinder conveying direction on the frame 1 to the cylinder receiving station, the lifting and rotating scanning centering station, and the warehousing docking station. The mobile trolley 500 is equipped with a roller assembly 501, which has a gap 502 allowing the rotating roller assembly of the lifting and rotating component 300 to pass through. The length of the carrying surface of the mobile trolley 500 is adjustable via a telescopic roller assembly frame to accommodate cylinders of different lengths.

[0032] 3. The lifting support assembly 200 is located below the gas cylinder receiving station. It includes a lifting mechanism 201 and a support roller assembly 202. The support roller assembly 202 is mounted on the lifting mechanism 201, and the lifting mechanism 201 can raise the support roller assembly 202 in the upward state. The lifting mechanism 201 may be a scissor mechanism.

[0033] Initially, the top of the support roller assembly 202 is lower than the trolley roller assembly 501 of the moving trolley 500. When the moving trolley 500 stops at the gas cylinder receiving station, the lifting mechanism 201 raises the support roller assembly 202. The support roller assembly 202 passes under the gap 502 of the trolley roller assembly 501, filling the gap 502. The support roller assembly 202 and the trolley roller assembly 501 form a temporary roller assembly of the same height, used to guide the gas cylinder smoothly into the middle of the moving trolley 500. At this time, the gas cylinder can be pushed out from the conveying roller assembly 106 by the moving push plate 101. After being pushed out, the gas cylinder passes through the trolley roller assembly 501 and the raised support roller assembly 202, smoothly reaching the middle position of the moving trolley 500. Originally, due to the presence of gap 502, small-sized gas cylinders would get stuck in it because of their size. However, after the lifting support assembly 200 was installed, it filled the gap 502, and the small-sized gas cylinders, supported by the continuous temporary roller assembly after filling, no longer got stuck in the gap 502. After the gas cylinders reached the vicinity of the middle position of the trolley, the lifting support assembly 200 lowered and reset, and the weight was independently borne by the trolley roller assembly 501.

[0034] IV. The lifting and rotating assembly 300 is located at the lower part of the lifting and rotating scanning and centering station, and includes a lifting mechanism 301, a transmission shaft 302, a rotating roller assembly, and a drive motor 305. The rotating roller assembly includes a passive roller assembly 303 and an active roller assembly 304.

[0035] The lifting mechanism 301 can be a scissor mechanism. Both the passive roller group 303 and the active roller group 304 are mounted on the lifting mechanism 301 to support the gas cylinder and drive its circumferential rotation. Specifically, both the passive roller group 303 and the active roller group 304 are arranged in two parallel rows. The drive motor 305 is mounted on the lifting mechanism 301 and connected to the active roller group 304 via a transmission shaft 302. Specifically, the output shaft of the drive motor 305 is connected to the transmission shaft 302 via a sprocket, and the transmission shaft 302 is connected to the active roller group 304 via a pulley with anti-slip texture.

[0036] V. The barcode scanning and centering assembly 400 is located on the upper part of the lifting and rotating barcode scanning and centering station, including a barcode scanner 401, a clamping and centering push plate 402, a centering drive mechanism 403, and a force feedback module.

[0037] Both the centering drive mechanism 403 and the barcode scanner 401 are mounted on the frame 1. The barcode scanner 401 faces downwards and is used to read the barcode on the top of the gas cylinder during rotation. A pair of clamping centering push plates 402 are arranged opposite each other and mounted on the centering drive mechanism 403. Each clamping centering push plate 402 has a force feedback module. The centering drive mechanism 403 drives the clamping rack and clamping gear set to achieve synchronous, opposite, or forward / backward movement of the pair of clamping centering push plates 402. The clamping surfaces of the clamping centering push plates 402 are covered with polyurethane or soft rubber material, and the length of the clamping centering push plates 402 is adjustable to accommodate gas cylinders of different lengths.

[0038] In this embodiment, when the mobile trolley 500 reaches the lifting and scanning rotation station, the two clamping and centering push plates 402 simultaneously clamp towards the center. During the clamping process, the force feedback module detects the contact force between the clamping and centering push plates 402 and the gas cylinder in real time. Due to the initial placement position of the gas cylinder, the contact state between the clamping and centering push plates 402 and the workpiece on both sides is different, resulting in a difference in the force on both sides. When the detected forces on both sides tend to be equal, it is determined that the gas cylinder has been centered and the gas cylinder is forcibly constrained to the preset center position, completing the mechanical centering. Then, the lifting mechanism 301 rises, and the bottom of the gas cylinder simultaneously contacts the passive roller group 303 and the active roller group 304. The drive motor 305 drives the gas cylinder to rotate along with it, and the support roller group 202 rotates with the gas cylinder as a driven support, thereby realizing the circumferential rotation of the gas cylinder until the barcode on the surface of the tank is aligned with the preset scanning position above. During this process, the barcode scanner 401 continuously reads the barcode label around the gas cylinder. Once the reading is successful, the rotation stops, the lifting mechanism 301 descends, and the gas cylinder falls back onto the mobile trolley 500, where it is independently supported by the trolley roller assembly 501.

[0039] After completing the alignment and scanning process, the mobile trolley 500 directly transports the gas cylinder to the receiving docking station. Three gaps are provided between the trolley's roller assembly 501 and the trolley body, forming three insertion ports for the forks 600. The middle insertion port is for small gas cylinders, and the two side insertion ports are for large gas cylinders. During subsequent inbound and outbound operations, the variable-width forks 600 on the warehouse side select the appropriate insertion port to insert and move the gas cylinder to complete the inbound process. The outbound process proceeds in reverse.

[0040] Furthermore, the surfaces of all the aforementioned roller assemblies are covered with a soft polyurethane or rubber material with a thickness of 3-10mm to protect the surface of the gas cylinder from scratches and collision damage during transport and positioning.

[0041] A working method for an adaptive inbound and outbound delivery system for multi-specification wound gas cylinders includes the following steps: S1: System initialization. Based on the specifications (diameter, length) of the gas cylinders to be conveyed, the height of the moving push plate 101, the spacing of the clamping and centering push plates 402, and the length of the bearing surface of the moving trolley 500 are automatically adjusted. The moving trolley 500 moves along the gas cylinder conveying direction on the frame 1 to the gas cylinder receiving station. S2: The upstream roller conveyor transports the gas cylinder to the conveyor roller assembly 106, and the V-shaped working surface of the conveyor roller assembly 106 automatically centers the gas cylinder. S3: The lifting mechanism 201 raises the support roller assembly 202, and the support roller assembly 202 passes through the gap 502 of the trolley roller assembly 501 from below, forming a temporary roller assembly with the trolley roller assembly 501. S4: The push drive mechanism 105 pushes the rocker arm frame 102 to move, the rocker arm frame 102 drives the moving push plate 101 to move, and the moving push plate 101 pushes the gas cylinder on the conveying roller group 106 onto the temporary roller group of the moving trolley 500. S5: The lifting support assembly 200 descends and resets, and the weight of the gas cylinder is independently borne by the trolley roller assembly 501; S6: The mobile trolley 500 transports the gas cylinder to the lifting, rotating, scanning, and centering station; S7: The centering drive mechanism 403 drives the two clamping centering push plates 402 to move synchronously towards each other, forcibly constraining the gas cylinder to the preset center position, thus completing the mechanical centering; S8: The lifting mechanism 301 is raised, and the rotating roller group passes through the gap 502 of the trolley roller group 501 from below, lifting the gas cylinder from the moving trolley 500. The drive motor 305 drives the active roller group 304 to rotate, thereby driving the gas cylinder to rotate slowly around the vertical axis. S9: The barcode scanner 401 continuously reads the barcode label on the surface of the gas cylinder during the cylinder's rotation. Once the reading is successful, the drive motor 305 immediately stops rotating. S10: The lifting and rotating assembly 300 descends and resets, and the gas cylinder falls back onto the moving trolley 500; S11: The mobile trolley 500 transports the gas cylinder to the fork docking station; the external forks 600 automatically select the corresponding insertion port according to the gas cylinder specifications; S12: The external forks 600 extend into the corresponding insertion port to pick up the gas cylinder and send it to the designated storage location in the automated warehouse. S13: The mobile trolley 500 returns to its initial position, waiting for the next gas cylinder to be delivered.

[0042] Furthermore, in step S1, the system can pre-read the specification information on the gas cylinder through the barcode scanner 401, or the operator can manually input the specification parameters to automatically complete the parameter adjustment of each mechanism.

[0043] Furthermore, in step S8, the rotation speed of the gas cylinder is controlled at 5-15 rpm to ensure that the barcode scanner 401 can accurately read the label, while avoiding damage caused by relative sliding between the gas cylinder surface and the roller assembly due to excessive rotation speed.

[0044] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components, etc. The above description is merely illustrative of the structure of the present invention. All equivalent changes made to the structure, features, and principles described in this patent concept, or simple changes made to the type of drive source, the arrangement of the roller assembly, etc., are included within the protection scope of this patent. Those skilled in the art can make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not deviate from the structure of the present invention or exceed the scope defined by the claims, all of which should fall within the protection scope of this invention.
