Description

Technical Field

[0001] This application relates to the field of material conveying and unloading, and in particular to a large fan product unloading device. Background Technology

[0002] In the fan manufacturing industry, industrialization is accelerating, and market demand for fan products continues to grow. Large HVLS (High Airflow, Low Speed) fans, in particular, are used for ventilation in large spaces such as aircraft hangars in aerospace applications and for auxiliary cooling in information technology data centers to reduce PUE (Power Usage Effectiveness). A fan production line is a complex and systematic project, encompassing multiple key stages including component processing, assembly, and final unloading. The efficient operation of each stage plays a crucial role in improving enterprise production efficiency. Among these, the unloading stage, as the final step in the production process, directly affects the smoothness of the entire production line. An efficient unloading stage can promptly transfer products off the production line, avoiding product accumulation and thus improving overall production efficiency.

[0003] In existing fan production lines, two common unloading methods are typically used. One is the suspended horizontal unloading mechanism, which is fixed above the production line and completes the unloading operation through pre-set tracks and programs. Specifically, it uses a track suspended above the production line, driven by a motor, to move the fan products from the production line to a designated location. This type of unloading mechanism cannot be moved freely, lacks flexibility, and is difficult to adapt to different production scenarios. When the production layout changes, this mechanism becomes ineffective. Therefore, another type of unloading mechanism has been developed. This mechanism has high flexibility and can move freely on the ground. It usually requires the use of a robotic arm to transfer the fan products from the production line's output end for unloading. Through precise programming and control, the robotic arm can accurately grasp and place the fan products, making it suitable for situations with special requirements for unloading position and angle.

[0004] However, existing ground-based mobile unloading mechanisms still have many shortcomings in practical applications. These shortcomings manifest in their complex structure and large size, which not only increases manufacturing costs but also requires significant space, increasing production costs and site burdens for enterprises. In particular, for large fans in industrial equipment, their weight makes them prone to loosening during unloading, and they also generate considerable noise. Summary of the Invention

[0005] To improve the efficiency and convenience of unloading large fan products, enable flexible movement to adapt to the needs of different production scenarios, reduce equipment manufacturing costs and space occupation, and effectively avoid product loosening and noise problems during the unloading process of existing unloading mechanisms, this application provides a large fan product unloading device.

[0006] A large fan product unloading device includes a frame that can be moved and placed on the production line conveying path, and a conveying mechanism, a positioning mechanism, a lifting mechanism, a transfer mechanism and an unloading mechanism disposed on the frame; The conveying mechanism includes a conveyor chain assembly and a roller assembly. The conveyor chain assembly is disposed on the conveying path of the production line and its conveying direction is consistent with the conveying direction of the production line. The conveying direction of the roller assembly is perpendicular to the conveying direction of the conveyor chain assembly. The positioning mechanism includes a material carrier plate and a limiting component disposed on the conveying path of the production line. The conveyor chain assembly conveys the material carrier plate containing the product to the loading station, and the limiting component is used to limit the material carrier plate. The lifting mechanism is located below the material plate and is used to lift the material plate upward to move it away from the limit component and reach the transfer station. The lifting mechanism includes a lifting drive component and a lifting plate. The lifting drive component drives the lifting plate to move vertically up and down. The top of the lifting plate is provided with a transfer roller group. The material plate is placed on the top of the lifting plate and its bottom is in rolling contact with the transfer roller group. The transfer mechanism pushes the material plate to slide on the transfer roller assembly so that the material plate can slide from the transfer station to the roller assembly, and the roller assembly will transfer the material plate to the unloading station; The unloading mechanism is used to remove the carrier plate on which the product is placed.

[0007] By adopting the above technical solution, the conveyor chain assembly in the conveying mechanism is set on the production line conveying path and its conveying direction is consistent with the production line conveying direction. This allows the material tray containing the product to be conveyed along the production line conveying direction, ensuring smooth connection with the production line and enabling the product to smoothly enter the unloading equipment. The roller assembly's conveying direction is perpendicular to the conveyor chain assembly, allowing the material tray to be conveyed in different directions, realizing a change in the product unloading direction and increasing unloading flexibility. The limiting component in the positioning mechanism limits the material tray, ensuring that the material tray accurately stops at the loading station, providing a stable foundation for subsequent operations. The lifting mechanism is set below the material tray. The lifting drive assembly drives the lifting plate to rise and fall vertically, lifting the material tray upwards to break free from the limiting component's limit and reach the transfer station, allowing the material tray to be smoothly transferred later and preventing the product from becoming loose. The transfer roller group at the top of the lifting plate makes rolling contact with the bottom of the material tray, reducing the friction when the material tray moves, facilitating the transfer mechanism to push the material tray to slide on the transfer roller group, and reducing noise. The transfer mechanism pushes the carrier plate from the transfer station to the roller assembly, which then conveys the carrier plate to the unloading station. This achieves orderly transfer of products from the production line to the unloading station, avoiding the loosening issues that can easily occur with clamping methods used in existing technologies. The unloading mechanism removes the carrier plate containing the product, completing a quick and convenient unloading operation. Overall, this unloading equipment, through the coordinated work of its various mechanisms, improves the efficiency and convenience of unloading large fan products, adapts to the needs of different production scenarios, and reduces equipment manufacturing costs and space occupation, while also minimizing product loosening and noise issues during the unloading process.

[0008] Preferably, the edge of the material carrier plate is provided with a limiting groove, and the limiting component includes a limiting cylinder and an L-shaped limiting block. The L-shaped limiting block includes a first free end, a bent end and a second free end. The bent end is hinged to the surface of the limiting cylinder, the piston rod of the limiting cylinder is fixedly connected to the first free end, and the second free end can be movably extended into the limiting groove to abut against the groove wall.

[0009] By adopting the above technical solution, when the piston rod of the limiting cylinder extends or retracts, it drives the L-shaped limiting block to rotate around the hinge point, allowing the second free end of the L-shaped limiting block to extend into the limiting groove of the carrier plate and abut against the groove wall. This enables precise positioning of the carrier plate, ensuring its positional stability during transport, preventing displacement or wobbling, and thus ensuring the smooth unloading of large fan products.

[0010] Preferably, the transfer roller assembly includes a mounting frame and a plurality of transfer rollers arranged horizontally on the mounting frame along the conveying direction of the roller assembly. Each transfer roller is rotatably mounted on the mounting frame via a horizontal pivot, and the bottom of the material carrier plate makes rolling contact with the top of each transfer roller.

[0011] By adopting the above technical solution, when the transfer mechanism pushes the material plate, the rolling of the transfer rollers can effectively reduce the friction when the material plate moves, so that the material plate can slide more smoothly on the transfer roller assembly, realize the smooth sliding from the transfer station to the roller assembly, and reduce noise.

[0012] Preferably, the transfer mechanism includes a transverse drive and a clamping component. The transverse drive drives the clamping component to move horizontally. The edge of the material carrier plate is provided with a positioning hole penetrating its upper and lower surfaces. The clamping component includes a transverse base, a drive cylinder, and a positioning column. The output end of the transverse drive is fixedly connected to the transverse base. The drive cylinder is fixedly disposed on the transverse base. The drive cylinder drives the positioning column to move vertically downward so that the positioning column can be inserted into the positioning hole.

[0013] By adopting the above technical solution, the transverse drive of the transfer mechanism drives the clamping component to move horizontally. When the carrier plate arrives at the transfer station, the drive cylinder drives the positioning column to move vertically downward. Since the carrier plate has positioning holes penetrating its upper and lower surfaces, the positioning column can accurately insert into the positioning holes, achieving a reliable connection to the carrier plate. Afterward, the transverse drive continues to drive the clamping component to move horizontally, which pushes the carrier plate to slide on the transfer roller assembly, allowing the carrier plate to smoothly slide from the transfer station to the roller assembly, thereby achieving stable transfer of the carrier plate and ensuring the smoothness and accuracy of the unloading process.

[0014] Preferably, the unloading mechanism includes a mobile vehicle carrier, an unloading plate, a positioning plate, and an adaptive lifting pad. The unloading plate is fixedly mounted on the movable mobile vehicle carrier, the roller assembly is mounted on the mobile vehicle carrier, the positioning plate is fixedly mounted above the end of the unloading plate away from the transfer station, and the adaptive lifting pad is mounted above the end of the unloading plate near the transfer station to provide a buffering effect and reduce noise.

[0015] By adopting the above technical solution, the unloading mechanism is equipped with a mobile carrier, allowing the unloading plate to move and facilitating flexible adjustment of the unloading position. Roller assemblies are installed on the mobile carrier to facilitate the transfer of the loading plate to the unloading station. A positioning plate is fixed above the end of the unloading plate furthest from the transfer station, providing positioning for the loading plate and ensuring it accurately stops at the unloading position. An adaptive lifting pad is positioned above the end of the unloading plate closest to the transfer station. When the loading plate slides from the transfer station to the unloading station, it first contacts the adaptive lifting pad, which provides cushioning and prevents direct collision between the loading plate and the unloading plate, effectively reducing noise.

[0016] Preferably, the bottom of the adaptive lifting pad is provided with an elastic lifting component, which includes a guide post, a spring and a connecting rod structure. The top of the guide post is fixed to the bottom of the adaptive lifting pad, and the bottom of the guide post slides through the unloading plate and is engaged with the connecting rod structure. The spring is disposed between the adaptive lifting pad and the unloading plate and is sleeved on the outer wall of the guide post.

[0017] By employing the above technical solution, when the product-laden carrier plate is transferred from the roller assembly to the unloading plate, it first contacts the adaptive lifting pad. Due to the weight of the carrier plate, it exerts downward pressure on the adaptive lifting pad, causing it to move downwards. At this time, the bottom of the guide column slides along the linkage structure, compressing the spring. The spring compression process absorbs the energy generated by the impact of the carrier plate, providing a cushioning effect. Simultaneously, the linkage structure ensures the stable movement of the guide column, preventing the adaptive lifting pad from tilting. Through the action of this elastic lifting component, the noise generated when the carrier plate contacts the unloading plate can be effectively reduced.

[0018] Preferably, the linkage structure includes a horizontal bar, a first vertical bar, and a second vertical bar. Both the first vertical bar and the second vertical bar are vertically fixed to the bottom of the unloading plate. One end of the horizontal bar slides with the bottom of the guide post, and the other end slides with the bottom of the first vertical bar. The middle part of the horizontal bar slides with the bottom of the second vertical bar.

[0019] By adopting the above technical solution, when the carrier plate moves onto the adaptive lifting pad, the adaptive lifting pad moves downward under pressure. Because the bottom of the adaptive lifting pad is equipped with an elastic lifting component, the guide column moves downward accordingly. The bottom of the guide column slides against one end of the crossbar. The downward movement of the guide column causes the crossbar to slide at the sliding contact point between the bottom of the first vertical bar and the bottom of the second vertical bar. This linkage structure ensures the stability of the adaptive lifting pad during descent, providing better cushioning and effectively reducing noise generated during the movement of the carrier plate.

[0020] Preferably, the crossbar is provided with a first guide groove, a second guide groove and a third guide groove, the bottom of the first vertical bar is provided with a first guide rod, the first guide rod slides in the first guide groove, the bottom of the second vertical bar is provided with a second guide rod, the second guide rod slides in the second guide groove, and the bottom of the guide post is provided with a wedge block, the wedge block slides in the third guide groove.

[0021] By adopting the above technical solution, when the adaptive lifting pad is subjected to pressure, the guide column moves downward and the wedge block slides in the third guide groove, driving the crossbar to move, so that the first guide rod and the second guide rod slide in the first guide groove and the second guide groove respectively. By utilizing this sliding cooperation of multiple components, the lifting process of the adaptive lifting pad can be made more stable and smooth, thereby providing a better buffering effect and effectively reducing the noise generated during the unloading process of large fan products.

[0022] Preferably, the frame is provided with a receiving cavity, and the mobile vehicle is disposed within the receiving cavity.

[0023] By adopting the above technical solution, the frame is equipped with a receiving cavity, and the mobile vehicle is placed inside the receiving cavity. This allows for effective storage and protection of the mobile vehicle, preventing damage from external environmental factors when it is not in use. At the same time, this arrangement makes the overall structure of the equipment more compact, reduces the space occupied by the equipment, optimizes the equipment layout, and improves space utilization.

[0024] Preferably, the conveying plane of the roller assembly is higher than the conveying plane of the conveyor chain assembly.

[0025] By adopting the above technical solution, since the conveying horizontal plane of the roller assembly is higher than that of the conveying horizontal plane of the conveyor chain assembly, it is easier for the material plate to be transferred from the conveyor chain assembly to the roller assembly, thus improving the smoothness of the material plate transfer.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. The equipment of this application can be moved and placed on the conveying path of the production line. Because it can move, its position can be flexibly adjusted according to different production scenarios, which is flexible and can adapt to the needs of different production scenarios. Multiple unloading devices can be placed on one production line at the same time; the unloading mechanism can quickly remove the material plate on which the product is placed to achieve rapid unloading.

[0027] 2. The conveyor chain component in the conveying mechanism is set on the production line conveying path and the conveying direction is consistent with the production line conveying direction, so that the product can smoothly enter the unloading equipment. The conveying direction of the roller component is perpendicular to the conveyor chain component, realizing the change of the product unloading direction, increasing the unloading flexibility, reducing the complexity and size of the equipment, and thus reducing manufacturing costs and space occupation. 3. The lifting drive assembly drives the lifting plate to move vertically up and down, which can lift the carrier plate upward and remove it from the limit assembly to reach the transfer station, so that the carrier plate can be smoothly transferred later and the product can be prevented from becoming loose. In addition, the transfer roller group at the top of the lifting plate makes rolling contact with the bottom of the carrier plate, reducing the friction when the carrier plate moves, making it easier for the transfer mechanism to push the carrier plate to slide on the transfer roller group and reducing noise.

[0028] 4. The bottom of the adaptive lifting pad in the unloading mechanism is equipped with an elastic lifting component. When the large fan arrives at the unloading plate along with the loading plate, the adaptive lifting pad is subjected to pressure, and the elastic lifting component deforms, thereby providing a buffering effect and reducing the noise generated by the large fan during the unloading process.

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application provides a large fan product unloading device, referring to... Figure 1Composed of several key components that work together to achieve efficient unloading of large fan products, the equipment includes a frame 1 that can be moved along the production line's conveyor path, and a conveying mechanism 2, a positioning mechanism 3, a lifting mechanism 4, a transfer mechanism 5, and an unloading mechanism 6 mounted on the frame 1. These mechanisms work in sequence to efficiently and stably unload large fan products, improving the flexibility and stability of the unloading process while reducing noise.

[0033] Reference Figure 1 Specifically, in this embodiment, the conveying mechanism 2 consists of a conveyor chain assembly 21 and a roller assembly 22. The conveying horizontal plane of the roller assembly 22 is higher than that of the conveyor chain assembly 21. The conveyor chain assembly 21 is disposed on the conveying path of the production line and its conveying direction is consistent with the conveying direction of the production line. The roller assembly 22 is disposed on the unloading mechanism 6 and its conveying direction is perpendicular to the conveying direction of the conveyor chain assembly 21.

[0034] The conveyor chain assembly 21 includes two sets of conveyor chains, which are respectively located on both sides of the positioning mechanism 3. Each conveyor chain consists of a chain, sprocket, and motor. The chain wraps around the sprocket, and the motor drives the sprocket to rotate, thus causing the chain to circulate and transport the product. The roller assembly 22 includes two sets of rollers, which are respectively located on both sides of the unloading mechanism 6. Each roller set consists of multiple rollers arranged in a row. The conveyor chain assembly 21 and the roller assembly 22 work together to enable the product to be transported in different directions, preparing for subsequent unloading operations.

[0035] Reference Figure 1 and Figure 2Specifically, the positioning mechanism 3 in this embodiment includes a material carrier plate 31 and a limiting component 32 disposed on the conveying path of the production line. The conveyor chain assembly 21 conveys the material carrier plate 31 containing the product to the loading station, and the limiting component 32 is used to limit the material carrier plate 31. The frame 1 is provided with an inlet 12 and an outlet 13 at both ends corresponding to the loading station. The product and the material carrier plate 31 enter the loading station through the inlet 12. The edge of the material carrier plate 31 is provided with a limiting groove 311. The limiting component 32 includes a limiting cylinder 321 and an L-shaped limiting block 322. The L-shaped limiting block 322 includes a first free end 3221, a bent end 3222 and a second free end 3223. The bent end 3222 is hinged to the surface of the limiting cylinder 321. The piston rod of the limiting cylinder 321 is fixedly connected to the first free end 3221, and the second free end 3223 can extend movably into the limiting groove 311 to abut against the groove wall. When the carrier plate 31 is conveyed to the loading station, the piston rod of the limiting cylinder 321 extends, pushing the L-shaped limiting block 322 to rotate around the hinge point, causing the second free end 3223 to extend into the limiting groove 311, thereby limiting the carrier plate 31 and preventing it from moving in subsequent operations. There are two limiting grooves 311 and limiting components 32, and their positions are arranged in a one-to-one correspondence. The limiting grooves 311 and limiting components 32 are located at the discharge port 13 end of the production line conveying path. Specifically, in this embodiment, the carrier plate 31 has a through hole in the middle, allowing the bottom of the fan product to extend into the through hole and be stably placed in the carrier plate 31.

[0036] Reference Figure 1 and Figure 3 Specifically, in this embodiment, the lifting mechanism 4 is disposed below the material plate 31 to lift the material plate 31 upward so that the material plate 31 can be released from the limiting component 32 and reach the transfer station a. The lifting mechanism 4 includes a lifting drive component 41 and a lifting plate 42. The lifting drive component 41 drives the lifting plate 42 to move vertically up and down. The top of the lifting plate 42 is provided with a transfer roller group 43. The material plate 31 is placed on the top of the lifting plate 42 and its bottom is in rolling contact with the transfer roller group 43.

[0037] The lifting drive assembly 41 can be a hydraulic cylinder, electric push rod, etc., which drives the lifting plate 42 to rise, causing the material plate 31 to break free from the limit assembly 32 and reach the transfer station a. The transfer roller assembly 43 includes a mounting frame 431 and multiple transfer rollers 432 arranged horizontally along the conveying direction of the roller assembly 22 on the mounting frame 431. Each transfer roller 432 is rotatably mounted on the mounting frame 431 via a horizontal rotating shaft. The bottom of the material plate 31 rolls in contact with the top of each transfer roller 432, allowing the material plate 31 to slide easily on the transfer roller assembly 43.

[0038] Reference Figure 2 and Figure 4Specifically, in this embodiment, the transfer mechanism 5 pushes the material plate 31 to slide on the transfer roller assembly 43, so that the material plate 31 slides from the transfer station a to the roller assembly 22, and the roller assembly 22 conveys the material plate 31 to the unloading station b. The transfer mechanism 5 includes a transverse drive 51 and a clamping member 52. The transverse drive 51 drives the clamping member 52 to translate. The edge of the material plate 31 is provided with a positioning hole 312 penetrating its upper and lower surfaces. The clamping member 52 includes a transverse seat 521, a drive cylinder and a positioning pin 522. The output end of the transverse drive 51 is fixedly connected to the transverse seat 521. The drive cylinder is fixedly disposed on the transverse seat 521. The drive cylinder drives the positioning pin 522 to move vertically downward so that the positioning pin 522 is inserted into the positioning hole 312. When the material carrier plate 31 arrives at the transfer station a, the drive cylinder drives the positioning column 522 to insert into the positioning hole 312, and the transverse drive component 51 pushes the transverse seat 521 to move horizontally, thereby causing the material carrier plate 31 to slide on the transfer roller group 43 and slide onto the roller assembly 22.

[0039] Reference Figure 1 and Figure 4 Specifically, in this embodiment, the unloading mechanism 6 is used to remove the loading plate 31 containing the product. The unloading mechanism 6 consists of a mobile vehicle carrier 61, an unloading plate 62, a positioning plate 63, an adaptive lifting pad 64, and an elastic lifting assembly 65. The unloading plate 62 is fixedly mounted on the movable mobile vehicle carrier 61, the roller assembly 22 is mounted on the mobile vehicle carrier 61, the positioning plate 63 is fixedly mounted above the end of the unloading plate 62 furthest from the transfer station a, and the adaptive lifting pad 64 is mounted above the end of the unloading plate 62 closest to the transfer station a to provide cushioning and reduce noise. The mobile vehicle carrier 61 can be a forklift, AGV, etc., to facilitate moving the unloading plate 62 and the product together.

[0040] The adaptive lifting pad 64 is provided with an elastic lifting component 65 at its bottom. The elastic lifting component 65 includes a guide post 651, a spring 652 and a connecting rod structure. The top of the guide post 651 is fixed to the bottom of the adaptive lifting pad 64, and the bottom of the guide post 651 passes through the unloading plate 62 and slides with the connecting rod structure. The spring 652 is located between the adaptive lifting pad 64 and the unloading plate 62 and is sleeved on the outer wall of the guide post 651.

[0041] Specifically, the linkage structure consists of a horizontal bar 653, a first vertical bar 654, and a second vertical bar 655. Both the first vertical bar 654 and the second vertical bar 655 are vertically fixed to the bottom of the unloading plate 62. One end of the horizontal bar 653 slides with the bottom of the guide post 651, and the other end slides with the bottom of the first vertical bar 654. The middle part of the horizontal bar 653 slides with the bottom of the second vertical bar 655. The horizontal bar 653 is provided with a first guide groove 6531, a second guide groove 6532, and a third guide groove 6533. The bottom of the first vertical bar 654 is provided with a first guide rod 656, which slides in the first guide groove 6531. The bottom of the second vertical bar 655 is provided with a second guide rod 657, which slides in the second guide groove 6532. The bottom of the guide post 651 is provided with a wedge block 658, which slides in the third guide groove 6533. When the loading plate 31 slides from the roller assembly 22 to the unloading plate 62, it first contacts the adaptive lifting pad 64. The adaptive lifting pad 64 descends under the action of the spring 652 and the connecting rod structure, which plays a buffering role and reduces noise. The frame 1 is provided with a receiving cavity 11, and the mobile vehicle 61 is set in the receiving cavity 11, which can save space and make the equipment layout more reasonable.

[0042] The implementation principle of this embodiment is as follows: The unloading equipment of this application conveys the material plate 31 containing the large fan product to the loading station along the production line conveying direction through the conveyor chain assembly 21. The piston rod of the cylinder in the limiting assembly 32 extends and pushes the L-shaped limiting block 322 to rotate around the bent end 3222, so that the second free end 3223 extends into the limiting groove 311 on the edge of the material plate 31, and precisely locks the material plate 31. Then, the lifting drive assembly 41 drives the lifting plate 42 to rise. The top transfer roller assembly 43 lifts the bottom of the carrier plate 31 and rolls it into contact with it. The carrier plate 31 then rises and moves away from the L-shaped limiting block 322 to the transfer station a. Then, the drive cylinder in the transfer mechanism 5 drives the positioning column 522 to move vertically downward and insert it into the positioning hole 312 on the edge of the carrier plate 31 to achieve rigid clamping. The transverse drive component 51 pushes the transverse seat 521 to move horizontally along the conveying direction of the roller assembly 22, causing the carrier plate 31 to move with low resistance on the transfer roller assembly 43. The material is slid and moved onto the roller assembly 22, which then conveys the material plate 31 perpendicular to the production line direction to the unloading station b. When the material plate 31 slides from the roller assembly 22 to the unloading plate 62, it first contacts the adaptive lifting pad 64. The pad is pressed down and moves downward, causing the wedge block 658 at the bottom of the guide column 651 to slide in the third guide groove 6533 of the crossbar 653. The wedge block 658 pushes the two ends of the crossbar 653 into the first guide groove 6531 and the second guide groove, respectively. Sliding within 6532, the first guide rod 656 at the bottom of the first vertical rod 654 and the second guide rod 657 at the bottom of the second vertical rod 655 slide in their respective guide grooves. The linkage structure converts the vertical impact force into a multi-directional dispersed force, while the spring 652 is compressed to absorb energy, achieving adaptive buffering and noise reduction. Finally, the mobile vehicle carrier 61 is removed from the receiving cavity 11 of the frame 1, and the unloading plate 62 is removed together with the product, completing the unloading. After each mechanism is reset in sequence, the next cycle begins.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
