Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, specifically a single-drive multi-layer streamlined conveying mechanism. Background Technology

[0002] Conveying mechanisms are an indispensable part of industrial automation, used for the efficient and continuous handling of materials. However, existing single-layer conveying structures can no longer meet the demands, leading to the increasing use of multi-layer conveying structures in automated production operations. However, existing multi-layer conveying devices require each layer to have its own power mechanism, resulting in high cost, complex structure, large size, and other problems such as inconvenient adjustment. For example, a multi-layer slack conveyor belt disclosed in patent publication number CN214102971U includes a first conveyor belt group, a second conveyor belt group, a third conveyor belt group, a fourth conveyor belt group, and a fifth conveyor belt group, forming a five-layer conveying structure. However, each conveyor belt group has its own motor for drive, resulting in a complex overall structure, large size, and high manufacturing cost. Utility Model Content

[0003] The purpose of this invention is to provide a single-drive, multi-layer streamlined conveyor mechanism to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a single-drive multi-layer streamlined conveying mechanism, including a mounting frame, wherein the mounting frame is a cuboid frame structure composed of four plates (upper, lower, left, and right), and multiple horizontal streamlined conveying lines are installed inside it. The multiple conveying lines are arranged vertically at intervals. A driving structure is provided on the left side of the mounting frame, and a connecting plate is provided on the side of the driving structure. The connecting plate is connected to a lifting linear module for adjusting the vertical position of the driving structure.

[0005] The conveyor system includes two belt conveyors mounted on the inner sides of two plates on the mounting frame. The two belt conveyors are arranged parallel to each other. Each belt conveyor is connected to a streamline drive shaft for driving the belt conveyor transmission. A rigid coupling connects the two streamline drive shafts. Both streamline drive shafts are rotatably connected to the mounting frame. The left end of the left one of the two streamline drive shafts is connected to a follower magnetic coupling. The drive structure includes an active magnetic coupling that cooperates with the follower magnetic coupling.

[0006] Further optimization includes a fixed base connected to a connecting plate, on which a horizontal drive device for driving the active magnetic coupling to move left and right is mounted, and above the horizontal drive device is a mounting base, on which a rotary drive assembly for driving the active magnetic coupling to rotate is mounted.

[0007] Preferably, the horizontal drive device is a slide cylinder.

[0008] In a further optimization, the rotary drive assembly includes a servo motor fixed on a mounting base. The output shaft of the servo motor is connected to a second drive wheel, which is connected to a second belt. The second belt is connected to a second driven wheel, and a rotating shaft is connected between the second driven wheel and the drive magnetic coupling. The end of the rotating shaft away from the drive magnetic coupling passes through the second driven wheel and is connected to a third bearing. A bearing housing is connected between the third bearing and the mounting base.

[0009] In a further optimization, the belt conveyor includes a first driving pulley mounted on a streamlined drive shaft, a first driven pulley rotatably mounted on a mounting bracket, and a first belt connecting the first driving pulley and the first driven pulley. A tension pulley is provided below the first belt. The first driving pulley, the first driven pulley, and the first belt constitute a belt conveyor structure.

[0010] Further optimization involves providing a support plate on the upper inner side of the first belt, which is fixed to the mounting frame to support the upper part of the first belt.

[0011] Further optimization involves providing a first bearing between the streamlined drive shaft and the mounting bracket, a support plate sleeved on the inner side of the streamlined drive shaft relative to the belt line, a fixed connection between the end of the support plate away from the streamlined drive shaft and the mounting bracket, and a second bearing between the support plate and the streamlined drive shaft to ensure smooth and stable rotation of the streamlined drive shaft.

[0012] Further optimization involves providing two first through-beam sensors on the upper and lower plates of the mounting frame, and multiple second through-beam sensors on the left and right plates of the mounting frame. The number of second through-beam sensors is the same as the number of conveyor lines, and each second through-beam sensor is positioned above a corresponding conveyor line to detect whether a product is present or not on the conveyor line.

[0013] Further optimization involves providing two clearance slots on the upper and lower plates of the mounting bracket to cooperate with the first through-beam sensor, facilitating the passage of the light beam; and providing multiple through holes on the left and right plates of the mounting bracket corresponding to the second through-beam sensor, facilitating the passage of the light beam.

[0014] Beneficial effects: The single-drive multi-layer streamlined conveyor mechanism of this utility model is composed of multiple layers of conveyor streamlines arranged at intervals, which can convey products at different heights and can also be used to convey different products. It has strong conveying capacity, high applicability and practicality, and can effectively reduce the volume and floor space of conveyor mechanisms for conveying multiple products, with a compact structure.

[0015] By combining the lifting linear module and the drive structure, a single-drive system is achieved, which can effectively reduce the manufacturing cost and difficulty of the equipment. The drive structure drives the belt of the conveyor to rotate through the combination of the active magnetic coupling and the follower magnetic coupling, thereby realizing the conveying capacity of the conveyor.

[0016] The conveying mechanism has a compact structure, enabling multi-layer product transfer within a small space. It has strong conveying capacity and small structural size, while the single-drive structure can effectively reduce manufacturing costs. Attached Figure Description

Detailed Implementation

[0024] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0025] like Figure 1 , Figure 2 and Figure 4 As shown, a single-drive multi-layer streamlined conveying mechanism includes a mounting frame 1, which is a cuboid frame structure composed of four plates: upper, lower, left, and right. Multiple horizontal streamlined conveying lines 2 are installed inside the mounting frame 1. The multiple conveying lines 2 are arranged vertically at intervals. A drive structure 3 is provided on the left side of the mounting frame 1. A connecting plate 4 is provided on the side of the drive structure 3. The connecting plate 4 is connected to a lifting linear module 5 for adjusting the vertical position of the drive structure 3.

[0026] The conveyor line 2 includes two belt lines 21 installed on the inner sides of the left and right plates of the mounting frame 1. The two belt lines 21 are arranged parallel to each other. Each belt line 21 is connected to a streamline drive shaft 22 for driving the belt line 21. A rigid coupling 23 is connected between the two streamline drive shafts 22. Both streamline drive shafts 22 are rotatably connected to the mounting frame 1. The left end of the left one of the two streamline drive shafts 22 is connected to a follower magnetic coupling 25. The drive structure 3 includes an active magnetic coupling 35 that cooperates with the follower magnetic coupling 25.

[0027] In this application, the conveying mechanism is a multi-layer streamlined conveying structure used in pallet manufacturing for conveying pallets (later replaced by products). It enables the conveying of products at different heights, achieving the purpose of product transport. The mounting frame 1 is used to install the conveyor lines 2, allowing multiple conveyor lines 2 to be stacked vertically. The mounting frame 1 consists of four mounting plates (top, bottom, left, and right) forming a rectangular frame structure. It has no front or rear mounting plates, being open at both ends to facilitate the forward and backward transport of products by the conveyor lines 2. The drive structure 3 is a single-drive structure, which can move up and down under the action of the lifting linear module 5, connecting with conveyor lines 2 at different heights to drive the corresponding conveyor lines 2, thus achieving the purpose of transporting products on the corresponding conveyor lines 2. This single-drive structure 3 effectively simplifies the conveying mechanism and reduces manufacturing costs.

[0028] In this application, the conveyor streamline 2 consists of two parallel belt conveyors 21 arranged side by side, forming a planar streamline for conveying products. A streamline drive shaft 22 drives the belt conveyors 21 to achieve the conveying function. The two belt conveyors 21 are connected by two streamline drive shafts 22 and a rigid coupling 23, ensuring synchronous conveying of the two belt conveyors 21. The rigid coupling 23 has a simple and compact structure, low cost, high transmission accuracy, strong rigidity and good stability, large torque transmission, and simple maintenance. Alternatively, a single long streamline drive shaft 22 can be used for connection. The follower magnetic coupling 25 is located on the left side of the mounting bracket 1 and is used to cooperate with the drive structure 3. The drive structure 3 is equipped with an active magnetic coupling 35. The rotation of the active magnetic coupling 35 generates a magnetic field. After sensing the magnetic field generated by the rotation of the active magnetic coupling 35, the follower magnetic coupling 25 can rotate synchronously with the active magnetic coupling 35. That is, when the active magnetic coupling 35 rotates, it can drive the follower magnetic coupling 25 to rotate synchronously. The rotation of the follower magnetic coupling 25 drives the streamline drive shaft 22 to rotate. The streamline drive shaft 22 drives the two belts 21 connected to it to drive synchronously, thus realizing the conveying function of the conveyor streamline 2.

[0029] In this application, the active magnetic coupling 35 and the follower magnetic coupling 25 are non-contact transmissions, with an air gap between them. This air gap is a mechanical connection that does not transmit torque, but the magnetic field passes through the air gap to transmit torque, thus achieving a non-contact connection. Through this non-contact connection, after the drive structure 3 is upgraded and adjusted, its active magnetic coupling 35 can cooperate with the follower magnetic coupling 25 of the corresponding conveyor line 2, driving the corresponding follower magnetic coupling 25 to rotate, thereby driving the transmission of the corresponding conveyor line 2. That is, with the cooperation of the upgraded linear module 5, the single-drive drive structure 3 can drive any one of the multiple vertically arranged conveyor lines 2.

[0030] like Figure 5 As shown, in one embodiment of this application, the drive structure 3 includes a fixed base 31 connected to the connecting plate 4. A horizontal drive device 32 for driving the active magnetic coupling 35 to move left and right is mounted on the fixed base 31. A mounting base 33 is connected above the horizontal drive device 32. A rotary drive assembly 34 for driving the active magnetic coupling 35 to rotate is mounted on the mounting base 33.

[0031] In this embodiment, the drive structure 3 includes a fixed base 31, a horizontal drive device 32, a mounting base 33, a rotary drive assembly 34, and an active magnetic coupling 35. The fixed base 31 is used to mount the horizontal drive device 32. The horizontal drive device 32 drives the mounting base 33, the rotary drive assembly 34, and the active magnetic coupling 35 to move left and right, allowing the active magnetic coupling 35 to move closer to and further away from the follower magnetic coupling 25. This facilitates adjustment of the gap between the active magnetic coupling 35 and the follower magnetic coupling 25, enabling adjustment of the torque and speed of the follower magnetic coupling 25, and also facilitates adjustment of the vertical position of the drive structure 3. The mounting base 33 is used to mount the rotary drive assembly 34. The horizontal drive device 32 drives the mounting base 33 to move left and right, achieving synchronous left and right movement of the rotary drive assembly 34. The rotary drive assembly 34 drives the active magnetic coupling 35 to rotate, thereby driving the follower magnetic coupling 25 to rotate, ultimately realizing the conveying function of the conveyor line 2.

[0032] Preferably, the horizontal drive device 32 is a slide cylinder, which has a compact structure and high guiding accuracy, and can significantly reduce the space occupied by the horizontal drive device 32 and reduce the resulting volume of the drive structure 3.

[0033] Furthermore, the rotary drive assembly 34 includes a servo motor 341 fixed on the mounting base 33. The output shaft of the servo motor 341 is connected to a second drive wheel 342, which is connected to a second belt 343. The second belt 343 is connected to a second driven wheel 344. A rotating shaft 345 connects the second driven wheel 344 to the active magnetic coupling 35. The end of the rotating shaft 345 away from the active magnetic coupling 35 passes through the second driven wheel 344 and is connected to a third bearing 346. A bearing housing 347 connects the third bearing 346 to the mounting base 33. The servo motor 341 drives the second drive wheel 342 to rotate. The second drive wheel 342 drives the second driven wheel 344 to rotate via the second belt 343. The second driven wheel 344 drives the rotating shaft 345 to rotate, ultimately causing the rotating shaft 345 to rotate the active magnetic coupling 35. The rotating shaft 345 is supported by the bearing housing 347. A third bearing 346 is provided between the rotating shaft 345 and the bearing housing 347 to support the rotating shaft 345 and the second driven wheel 344 and ensure the smooth rotation of the rotating shaft 345.

[0034] like Figure 4 As shown, in another embodiment of this application, the belt 21 includes a first drive wheel 211 mounted on the streamlined drive shaft 22, a first driven wheel 212 rotatably mounted on the mounting bracket 1, and a first belt 213 connecting the first drive wheel 211 and the first driven wheel 212. A tensioning wheel 214 is provided below the first belt 213.

[0035] In this embodiment, the belt conveyor 21 includes a first driving pulley 211, a first driven pulley 212, and a first belt 213. The first belt 213 connects the first driving pulley 211 and the first driven pulley 212. The rotation of the first driving pulley 211 drives the first driven pulley 212 and the first belt 213 to drive synchronously, thereby realizing the conveying function of the belt conveyor 21. The tensioning pulley 214 is located below the first belt 213. By adjusting the height of the tensioning pulley 214, the pressure adjustment of the tensioning pulley 214 relative to the first belt 213 is realized, ultimately achieving the tension adjustment of the first belt 213.

[0036] Furthermore, a support plate 28 is provided on the upper inner side of the first belt 213, and the support plate 28 is fixed on the mounting frame 1. Through the structural arrangement of the support plate 28, the upper half of the first belt 213 can be supported, and the product conveyed on the first belt 213 can be supported, controlling the sag of the first belt 213 and ensuring smooth product conveying.

[0037] Continue to refer to Figure 4 As shown, in another embodiment of this application, a first bearing 24 is provided between the streamlined drive shaft 22 and the mounting frame 1, a support plate 26 is sleeved on the inner side of the streamlined drive shaft 22 relative to the belt line 21, the end of the support plate 26 away from the streamlined drive shaft 22 is fixedly connected to the mounting frame 1, and a second bearing 27 is provided between the support plate 26 and the streamlined drive shaft 22.

[0038] In this embodiment, the streamlined drive shaft 22 is rotatably connected to the mounting frame 1 via a first bearing 24. A support plate 26 supports the streamlined drive shaft 22, forming a dual-point support structure with the first bearing 24 and the support plate 26, ensuring the smooth operation of the streamlined drive shaft 22 and thus guaranteeing the structural stability of the conveyor stream 2. The support plate 26 is connected to the streamlined drive shaft 22 via a second bearing 27, ensuring smooth rotation of the streamlined drive shaft 22.

[0039] like Figure 3 As shown, in another embodiment of this application, two first through-beam sensors 6 are provided on the upper and lower plates of the mounting frame 1, and multiple second through-beam sensors 7 are provided on the left and right plates of the mounting frame 1. The number of second through-beam sensors 7 is the same as the number of conveyor lines 2, and each second through-beam sensor 7 is correspondingly disposed above a conveyor line 2.

[0040] In this embodiment, two first through-beam sensors 6 are positioned vertically to detect whether a product has entered the conveyor line 2 and the height of the pallet and product corresponding to the conveyor line 2. A second through-beam sensor 7 is used to detect the corresponding conveyor line 2, indicating whether a product is being conveyed there. The first and second through-beam sensors 6 and 7 ensure accurate product delivery. Each through-beam sensor includes a transmitter and a receiver. The transmitter emits a light beam, and the receiver detects whether the beam is blocked by an object, triggering a signal change to achieve object detection.

[0041] Furthermore, both the upper and lower plates of the mounting bracket 1 are provided with two clearance slots 11 that mate with the first through-beam sensor 6, and both the left and right plates of the mounting bracket 1 are provided with multiple through holes 12 corresponding to the second through-beam sensor 7. The clearance slots 11 are used for the installation clearance of the first through-beam sensor 6 and to prevent the beam emitted by the transmitter of the first through-beam sensor 6 from being blocked. The through holes 12 facilitate the passage of the beam emitted by the second through-beam sensor 7, ensuring the effective detection of the second through-beam sensor 7.

[0042] In this application, the conveying mechanism has twenty conveying flow lines 2. When a product needs to be conveyed on one of the conveying flow lines 2 (including backward or forward conveying), the lifting linear module 5 lifts the drive structure 3 to the height of the corresponding conveying flow line 2. The horizontal drive device 32 pushes it to the right, pushing the rotary drive assembly 34 and the active magnetic coupling 35 to the working position to match the follower magnetic coupling 25 of the corresponding conveying flow line 2. Then, the servo motor 241 drives the second drive wheel 342 to rotate, which drives the active magnetic coupling 35 to rotate through the second belt 343, the second driven wheel 344 and the rotating shaft 345. The active magnetic coupling 35 achieves non-contact torque transmission through magnetic field coupling, driving the follower magnetic coupling 25 to rotate, thereby driving the conveying flow line 2 to operate and realize the conveying of the product.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
