Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a T-shaped material logistics conveying system. Background Technology

[0002] With the continuous advancement of key projects and the booming development of the shipping industry, the large shipbuilding industry has ushered in new growth opportunities. As a key component in ship structure manufacturing, the market demand for T-sections continues to rise. To meet the requirements of efficient and mass production, automated welding equipment has been widely used in heavy industry enterprises, becoming an important means to improve manufacturing efficiency and ensure product quality.

[0003] In the welding and manufacturing process of T-profiles, the welded T-profiles need to undergo a straightening process to ensure their geometric accuracy meets the requirements of subsequent assembly or use. However, in existing technologies, welded T-profiles are mostly manually hoisted to the input end of the straightening machine, which has many drawbacks. First, the hoisting process requires manual operation, posing a high safety risk, especially when handling large and heavy T-profiles, where even slight carelessness can lead to accidents. Second, manual hoisting is inefficient and cannot meet the cycle time requirements of mass production, thus limiting the overall automation level of the production line. In addition, frequent manual intervention also leads to high labor intensity, increases the workload of workers, and affects the continuity and stability of production. Summary of the Invention

[0004] Therefore, this utility model provides a T-shaped profile logistics conveying system, which realizes the automatic conveying of T-shaped profiles to the straightening station after welding, so as to improve the level of automation and production efficiency, reduce labor intensity and ensure production safety.

[0007] A first flipping machine, housed within the conveyor roller conveyor, includes a plurality of first flipping components distributed along a second direction, each flipping component located on one side of the conveyor roller conveyor along a third direction. Each first flipping component includes a first state and a second state. When the T-profile is conveyed to the position of the first flipping machine, and when the first flipping component changes from the first state to the second state, it can cause the T-profile to flip from a vertical state to a horizontal state. The vertical state is when the horizontal plate of the T-profile contacts the conveyor roller conveyor and the vertical plate faces upwards; the horizontal state is when both the vertical and horizontal plates of the T-profile simultaneously contact the conveyor roller conveyor.

A first sprocket is provided at one end of the roller, and a first chain is installed between the plurality of first sprockets. The drive end of the first drive motor is connected to the first chain, and a plurality of interval spaces for accommodating the first tilting machine are provided in the conveying roller conveyor.

[0015] In one embodiment of this utility model, the transverse movement device further includes a second connecting rod, a coupling, a mounting base, and a lifting device. One end of the transverse movement arm is connected to the lifting device, and the other end of the transverse movement arm is rotatably connected to the mounting base.

[0016] The conveying structure includes a conveying chain, a second sprocket, a second chain, and a second drive motor;

[0017] The conveyor chain is mounted on the transverse arm, and a drive wheel is provided between one end of the conveyor chain and the transverse arm.

[0021] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art:

[0022] This utility model discloses a T-shaped profile logistics conveying system. Through the organic coordination of the conveyor roller conveyor, the first tilting machine, the lateral movement device, and the second tilting machine, it realizes a series of actions such as automatic tilting, lateral movement, and re-tilting of the T-shaped profiles after welding, ensuring the automation, continuity, and safety of the conveying process. It effectively avoids the safety risks and efficiency bottlenecks caused by manual hoisting, improves the automation level and production cycle of the production line, significantly reduces labor intensity, and ensures efficient and stable production operation.

[0023] This invention uses a first flipping machine to flip the T-shaped profile from a vertical position to a horizontal position for transport, so that its horizontal and vertical plates simultaneously contact the conveyor rollers. This lowers the center of gravity and increases the support surface, effectively avoiding instability problems such as deviation and overturning caused by vibration, impact, or speed changes, and ensuring the continuity and reliability of the conveying process.

[0024] Before lateral movement and correction, this utility model uses a second flipping machine to restore the T-profile from a horizontal to a vertical state, ensuring that the horizontal plate fits into the input roller of the straightening machine and the vertical plate faces upward, meeting the clamping requirements for vertical plate or overall geometric correction, and improving correction accuracy and work efficiency.

[0025] The first flipping assembly of this utility model uses a first flipping arm and a second flipping arm connected to form a predetermined angle. During the flipping process, the two flipping surfaces contact the horizontal plate and vertical plate of the workpiece respectively, realizing multi-point support and stable clamping, preventing slippage and displacement, ensuring smooth and reliable flipping action, and adapting to the flipping needs of T-shaped profiles of different specifications and sizes.

[0026] The conveyor roller of this utility model consists of a frame, rollers, bearing seats and drive motor. The rollers rotate smoothly through the bearing seats, with low noise and easy maintenance. The sprocket and chain work together to drive the power transmission efficiently. The space between the rollers is used to integrate the first turning machine. The system has a high degree of integration and high space utilization.

[0027] This utility model's lateral moving arm achieves workface lifting and lowering through a lifting device. The conveyor chain, combined with sprockets, chains, and a second drive motor, is compact in structure and provides stable power transmission. It maintains the workpiece's posture during lateral movement, improving transportation safety. The lifting device is driven by a second hydraulic cylinder and connects the lateral moving arm to the mounting base via a pin and a rotating shaft, ensuring smooth lifting and lowering of the lateral moving arm, avoiding interference with the conveyor rollers, and improving equipment operational safety.

[0028] In the horizontal position, the T-shaped profile has a low center of gravity. It can be restored to the vertical position by simply rotating it 90 degrees with a single third flipping arm. No additional clamping or support is required. The flipping is completed by utilizing the workpiece's own weight and the torque of the flipping arm. The flipping process is stable and controllable, providing a reliable posture for subsequent correction. Attached Figure Description

[0051] Reference Figure 1 , Figure 2 As shown, the present invention provides a T-shaped profile logistics conveying system, comprising:

[0052] Conveying roller conveyor 2 extends along a first direction for conveying T-shaped profiles; wherein the T-shaped profiles extend along the first direction during conveying.

[0053] A first flipping machine 1 is housed within the conveyor roller conveyor 2 and includes a plurality of first flipping components distributed along a second direction. Each flipping component is located on one side of the conveyor roller conveyor 2 along a third direction. Each first flipping component includes a first state and a second state. When the T-profile is conveyed to the position of the first flipping machine 1, and when the first flipping component changes from the first state to the second state, it can cause the T-profile to flip from a vertical state to a horizontal state. The vertical state is when the horizontal plate of the T-profile contacts the conveyor roller conveyor and the vertical plate faces upwards; the horizontal state is when both the vertical and horizontal plates of the T-profile simultaneously contact the conveyor roller conveyor. The first direction, the second direction, and the third direction are perpendicular to each other.

[0054] The transverse transfer device 3 includes a plurality of transverse transfer arms 3.1 distributed along a first direction. Each transverse transfer arm 3.1 is located on one side of the conveyor roller table 2 along a third direction and extends along the second direction. Each transverse transfer arm 3.1 is provided with a conveying structure. When the T-profile is conveyed to the position of the chain transverse transfer device 3, one end of the transverse transfer arm 3.1 can be lifted along a third direction so that the conveying structure extends out of the surface of the conveyor roller table 2.

[0055] The second flipping machine 4 is disposed on one side of the conveyor roller 2 along the second direction and is connected to each of the transverse arms 3.1. The second flipping machine 4 includes a second flipping component, which includes a first state and a second state. When the T-profile is conveyed to the position of the flipping machine by the conveying structure, when the second flipping component changes from the first state to the second state, it can flip the T-profile in the horizontal state to the vertical state.

[0056] It should be noted that during vertical transport, because the vertical plates of the T-profile are facing upwards, the center of gravity is relatively high. During transport, if subjected to vibration, impact, or changes in transport speed, it is prone to swaying or tipping, especially long or large T-profiles, which are at higher risk of instability. During horizontal transport, both the horizontal and vertical plates of the T-profile simultaneously contact the conveyor rollers 2, increasing the support surface and lowering the center of gravity, making it more stable during transport. This avoids problems such as deviation and tipping due to unstable posture, improving the reliability of the transport process. This postural stability helps ensure the continuity of transport and reduces the risk of abnormal downtime or workpiece damage.

[0057] Existing vertical conveying systems typically require additional clamping or anti-tipping devices to prevent T-profiles from tipping over during transport. These devices increase the complexity of the conveying system, require synchronized operation, are difficult to control, and have high maintenance costs. Horizontal conveying, on the other hand, achieves stable transport solely through the workpiece's own weight and the support of the contact surface, eliminating the need for additional clamping or limiting structures. This simplifies the design of the conveying system, reduces equipment manufacturing costs and maintenance difficulty, and improves the overall level of automation and economy.

[0058] In addition, the straightening machine has specific requirements for the posture of the T-profile. Usually, the T-profile needs to be in a vertical position, that is, the horizontal plate is in contact with the input roller of the straightening machine and the vertical plate is facing upward, so as to perform geometric correction of the vertical plate or the whole.

[0059] Therefore, after horizontal transport, the T-profile is flipped back to a vertical position by the second flipping machine 4 to ensure that its posture meets the clamping and correction process requirements of the straightening machine, thereby improving the straightening accuracy and work efficiency.

[0060] In one embodiment, refer to Figure 3 , Figure 4 As shown, the first flipping assembly includes a first flipping arm 1.2 and a second flipping arm 1.8 connected together. The first flipping arm 1.2 includes a first flipping surface 1.2.1, and the second flipping arm 1.8 includes a second flipping surface 1.8.1. The first flipping surface 1.2.1 and the second flipping surface 1.8.1 form a predetermined angle. When the first flipping assembly changes from a first state to a second state, the first flipping surface 1.2.1 and the second flipping surface 1.8.1 respectively contact the T-shaped profile. The first flipping assembly is connected by the first flipping arm 1.2 and the second flipping arm 1.8, forming a predetermined angle slightly less than 90 degrees, so that the two flipping surfaces respectively contact the T-shaped profile during the flipping process, providing stable support, preventing the workpiece from slipping during the flipping process, and ensuring a smooth and reliable flipping action.

[0061] Understandably, when the T-profile is in its vertical position, with the vertical plate facing upwards and the horizontal plate attached to the conveyor roller 2, the center of gravity is high and the posture is unstable. If it is pushed by only one flipping arm during the flipping process, the vertical plate will be at risk of tipping over, slipping, or shifting due to its own weight.

[0062] Two flipping arms (i.e., the first flipping arm 1.2 and the second flipping arm 1.8) are used, so that the corresponding first flipping surface 1.2.1 and second flipping surface 1.8.1 form an angled structure. During the flipping process, the two flipping surfaces contact different parts of the T-profile (such as the horizontal and vertical plates), achieving multi-point support and stable clamping. This effectively prevents the T-profile from shifting or tipping due to changes in the center of gravity during the flipping process, ensuring smooth flipping and controllable posture. The coordinated action of the two flipping arms provides sufficient support area and, through the angled design, rationally distributes the flipping torque, making the flipping action more stable and adaptable to the flipping needs of T-profiles of different specifications and sizes.

[0063] In one embodiment, when the first flipping component changes from a first state to a second state, the first flipping arm 1.2 flips 90 degrees, and the length of the first flipping arm 1.2 is greater than the length of the second flipping arm 1.8.

[0064] In one embodiment, the first tilting machine 1 further includes a first frame 1.1, an intermediate shaft 1.3 disposed on the first frame 1.1, a first hydraulic cylinder 1.5 mounted on the first frame 1.1, and a first connecting rod 1.7 connected to the driving end of the first hydraulic cylinder 1.5. The second tilting arm 1.8 is rotatably connected to the first frame 1.1 through the intermediate shaft 1.3. A first pin 1.4 connected to the first connecting rod 1.7 is disposed between the first tilting arm 1.2 and the second tilting arm 1.8. A second pin 1.6 is disposed between the mounting end of the first hydraulic cylinder 1.5 and the first frame 1.1.

[0065] In one embodiment, a plurality of first flipping machines 1 are distributed along a first direction, and each of the first flipping components of each first flipping machine 1 is correspondingly arranged.

[0066] In one embodiment, refer to Figure 5 , Figure 6As shown, the conveyor roller conveyor 2 includes a second frame 2.1, rollers 2.2, bearing seats 2.3, and a first drive motor 2.6; multiple rollers 2.2 are distributed on the second frame 2.1 along a first direction, and both ends of the rollers 2.2 are rotatably connected to the second frame 2.1 through the bearing seats 2.3. A first sprocket 2.4 is provided at one end of the rollers 2.2, and a first chain 2.5 is installed between multiple first sprockets 2.4. The drive end of the first drive motor 2.6 is connected to the first chain 2.5. The conveyor roller conveyor 2 is provided with a plurality of interval spaces 2.7 for accommodating the first turning machine 1.

[0067] With the above configuration, the conveyor roller conveyor 2 consists of a second frame 2.1, a roller 2.2, a bearing seat 2.3, and a first drive motor 2.6. The roller 2.2 is rotatably connected through the bearing seat 2.3, resulting in smooth transmission, low noise, and easy maintenance. The first sprocket 2.4 cooperates with the first chain 2.5 and is driven by the first drive motor 2.6, ensuring efficient power transmission and smooth advancement of the T-shaped profile during the conveying process, avoiding jamming, and guaranteeing conveying efficiency. An interval space 2.7 is provided in the conveyor roller conveyor 2 to accommodate the first tilting machine 1, ensuring the organic integration of the tilting device and the conveying structure, and improving the overall integration and space utilization of the system.

[0068] In one embodiment, refer to Figures 8 to 10 As shown, the transverse movement device 3 also includes a second connecting rod 3.8, a coupling 3.9, a mounting base 3.2, and a lifting device. One end of the transverse movement arm 3.1 is connected to the lifting device, and the other end of the transverse movement arm 3.1 is rotatably connected to the mounting base 3.2. Multiple second connecting rods 3.8 are connected by the coupling 3.9.

[0069] The conveying structure includes a conveying chain 3.10, a second sprocket 3.11, a second chain 3.12, and a second drive motor 3.13;

[0070] The conveyor chain 3.10 is mounted on the transverse arm 3.1, and a drive wheel is provided between one end of the conveyor chain 3.10 and the transverse arm 3.1. The connecting rod is equipped with a second sprocket 3.11 corresponding to each transverse arm 3.1. A second chain 3.12 is installed between the corresponding drive wheel and the second sprocket 3.11. The second connecting rod 3.8 is driven to rotate by the second drive motor 3.13.

[0071] With the above-mentioned configuration, the transverse movement device 3 is equipped with a second connecting rod 3.8, a coupling 3.9, a mounting base 3.2, and a lifting device. Its compact structure and stable power transmission enhance the stability of the transverse movement system. The conveying structure uses a combination of sprockets, chains, and a conveyor chain 3.10, coupled with a second drive motor 3.13. This results in high power transmission efficiency, smooth and reliable transportation, and avoids changes in the posture of the T-profile during transverse movement, thus improving transportation safety.

[0072] Reference Figure 10 As shown, the lifting device includes a cylinder mounting base 3.6 and a second cylinder 3.5 mounted on the cylinder mounting base 3.6. The driving end of the second cylinder 3.5 is connected to one end of the transverse arm 3.1. A third pin 3.4 is provided between one end of the transverse arm 3.1 and the driving end of the second cylinder 3.5, and a fourth pin 4.3 is provided between the second cylinder 3.5 and the cylinder mounting base 3.6. A rotating shaft 3.3 is provided between the other end of the transverse arm 3.1 and the mounting base 3.2. The lifting device is driven by the second cylinder 3.5, and the cylinder mounting base 3.6 and the transverse arm 3.1 are connected by pins and rotating shafts 3.3. The operation is smooth, the structure is reliable, ensuring a smooth lifting process, improving the efficiency and stability of the lifting and lowering of the conveyor chain 3.10, avoiding workpiece transport interference, and improving equipment safety.

[0073] In one embodiment, refer to Figure 11 , Figure 12 As shown, the second flipping machine 4 includes a third frame 4.1, a third hydraulic cylinder 4.4, and a third flipping arm 4.2. The third flipping arm 4.2 is rotatably connected to the third frame 4.1. The third hydraulic cylinder 4.4 is mounted on the third frame 4.1 and its drive end is connected to the third flipping arm 4.2. The third hydraulic cylinder 4.4 flips the third flipping arm 4.2 from a horizontal state by 90 degrees, so that the T-profile is flipped from a horizontal state to a vertical state.

[0074] It should be noted that when the T-profile is in a horizontal position, both the horizontal and vertical plates are in contact with the conveyor rollers 2, resulting in a low center of gravity and stable posture. In this case, flipping the T-profile only requires lifting one side and rotating it 90 degrees to restore its vertical position. A single flipping arm (the third flipping arm 4.2 in the second flipping machine 4) can apply force along one side edge of the T-profile. Utilizing the T-profile's own weight and the pushing torque of the third flipping arm 4.2, the entire flipping action is completed without additional clamping or support, making the flipping process smooth and controllable.

[0075] In one embodiment, a fourth pin 4.3 is provided between the third tilting arm 4.2 and the third frame 4.1, a fifth pin 4.5 is provided between the third cylinder 4.4 and the third frame 4.1, and a sixth pin 4.6 is provided between the front end connector of the third cylinder 4.4 and the third tilting arm 4.2.

[0076] It should be noted that during horizontal transport, the T-profiles are held tightly against the conveyor rollers 2 or conveyor chain 3.10 under the influence of gravity, resulting in higher transport stability. Supported by both horizontal and vertical contact surfaces, transport is more stable, preventing accidental collisions and overturning or impacts caused by sudden vibrations, thus avoiding damage to equipment or workpieces and improving production safety. Especially for large or heavy T-profiles, horizontal transport effectively avoids safety accidents caused by the high center of gravity during vertical transport.

[0077] The working principle of this utility model is as follows: After welding, the T-shaped profile is located on the conveyor roller 2. In the first turning machine 1, the first hydraulic cylinder 1.5 is activated, and the first turning arm 1.2, which is embedded in the first turning machine 1 below the conveyor roller 2, swings 90 degrees, changing from a horizontal to a vertical state. The first hydraulic cylinder 1.5 is controlled so that the first turning surface 1.2.1 and the second turning surface 1.8.1 always form a fixed angle, clamping and turning the T-shaped profile so that it turns from a vertical state to a horizontal state. In the conveyor roller 2, the first drive motor 2.6 is activated, and the T-shaped profile, which has turned to a horizontal state, is conveyed forward to the transverse transfer device 3. In the transverse transfer device 3, the second hydraulic cylinder 3.5 is activated, and the working surface of the conveyor chain 3.10 on the transverse transfer arm 3.1 is lifted to a height above the top surface of the roller 2.2 in the conveyor roller 2. The second drive motor 3.13 is activated, and the T-shaped profile on the conveyor chain 3.10 is conveyed to the second turning machine 4 at the input roller of the straightening machine. Lower the second hydraulic cylinder 3.5 so that the conveyor chain 3.10 is lower than the roller table surface. In the second turning machine 4, start the third hydraulic cylinder 4.4 to turn the third turning arm 4.2 90 degrees, so that the T-profile is turned from a horizontal state to a vertical state. After the T-profile is sent into the straightening machine via the straightening machine input roller table, start the third hydraulic cylinder 4.4 to return to the initial position.

[0078] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to examples, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
