Description

Technical Field

[0001] This application relates to the field of conveying device technology, and in particular to a multifunctional rotary conveying device. Background Technology

[0002] Conveyors can transport packaged materials with flat bottoms, such as plates, bars, pipes, profiles, pallets, boxes, and various workpieces, along horizontal or small angles of inclination. For non-flat bottom materials and flexible materials, pallets can be used for conveying. They are characterized by simple structure, reliable operation, convenient maintenance, economy, and energy saving.

[0003] Conveyors are widely used in industrial production. With technological advancements, the types and functions of conveyors have become increasingly diverse. Rotary conveyors are one such example. They combine the functionality of traditional conveyors with rotation, allowing for changes in the direction of material transport. This eliminates site limitations. Besides changing the direction of material transport, rotary conveyors can also adjust the orientation of materials in certain special transport scenarios. For instance, during product packaging and transport, boxes may need to be rotated at a certain angle to change their orientation before being transported, facilitating labeling by the labeling devices on both sides of the conveyor belt. Existing rotary conveyors... A rotary conveyor typically incorporates a liftable rotating mechanism within an existing conveyor system. This rotary conveyor is positioned between two conveyor belts. The first conveyor belt transports material to the rotary conveyor, which then transports the material above the rotating mechanism. The rotating mechanism rises, lifts the material, rotates it a certain angle, and then descends to lower the material back onto the conveyor. The conveyor then continues transporting the material to the second conveyor belt. The main drawback of this rotary conveyor is that the rotating mechanism needs to reset after rotating the material and wait for the material to move before it can rotate on the next material. This prevents continuous rotary conveying operations, resulting in low efficiency. Furthermore, the rotary conveyor can only change the orientation of the material, making its function limited. Summary of the Invention

[0004] To address the problem that existing rotary conveyors require resetting after rotating materials and can only rotate after the previous material has been transported away, resulting in low efficiency and inability to achieve continuous rotational operations, this application provides a multifunctional rotary conveying device.

[0005] This application provides a multifunctional rotary conveying device with the following technical solution: A multifunctional rotary conveying device includes a base, a main frame, and two sets of belt conveyor assemblies. The two sets of belt conveyor assemblies are symmetrically fixed above the main frame. The bottom of the main frame is connected to the base through a rotating mechanism. A roller conveyor assembly with a conveying direction perpendicular to the conveying direction of the belt conveyor assemblies is provided between the two sets of belt conveyor assemblies. The bottom of the roller conveyor assembly is connected to the base through a lifting assembly. The lifting assembly can drive the roller conveyor assembly to reciprocate up and down during the rotation of the main frame. The lifting assembly includes at least two arc-shaped lifting tracks arranged on the base. The height of the lifting tracks gradually increases along the circumferential direction. A lifting assembly is connected to the bottom of the roller conveyor assembly. The lifting assembly can extend downward into the lifting tracks and move freely along the lifting tracks. It also includes a sensor assembly for detecting the position of the roller conveyor assembly. The sensor assembly includes two proximity sensors arranged vertically. The two proximity sensors are fixedly installed on one side of the belt conveyor assembly through a mounting plate. A trigger is provided on one side of the roller conveyor assembly corresponding to the proximity sensors.

[0006] By adopting the above technical solution, in the initial state, the height of the roller conveyor assembly is lower than that of the belt conveyor assembly. The material is conveyed onto the belt conveyor assembly via the conveyor belt. The belt conveyor assembly conveys the material to the middle position of the rotary conveyor. Then, the rotating mechanism drives the main frame to rotate. During the rotation of the main frame, the roller conveyor assembly rotates. The lifting assembly at the bottom of the roller conveyor assembly moves with the roller conveyor assembly. The lifting assembly moves along the arc-shaped lifting track. Since the height of the lifting track gradually increases along the circumference, the lifting assembly lifts the roller conveyor assembly upwards during its movement along the lifting track, thus achieving simultaneous lifting and lowering while the roller conveyor assembly rotates. After the main frame rotates 90 degrees, the roller conveyor assembly rises to a height higher than the belt conveyor assembly. At this time, the material detaches from the belt conveyor assembly and is located on the roller conveyor assembly. At this time, the roller conveyor assembly connects to the conveyor belt, and the roller conveyor assembly conveys the material, allowing the material to enter the conveyor belt. At this time, the angle of the material has rotated 90 degrees. After the material enters the conveyor belt from the rotary conveyor, the conveyor belt conveys the next material to the roller conveyor. The roller conveyor assembly is positioned on the main frame. The rotating mechanism then reverses and resets, while the lifting assembly synchronously drives the roller conveyor assembly to descend. After the rotating mechanism drives the main frame to rotate 90 degrees and reset, the roller conveyor assembly is lower than the belt conveyor assembly. The material is positioned on the belt conveyor assembly and connected to the conveyor belt. The belt conveyor assembly transports the material to the conveyor belt, reciprocating to achieve automated material conveying. When the roller conveyor assembly is in its original position, a trigger on one side of the roller conveyor assembly corresponds to a proximity sensor below one side of the belt conveyor assembly. The proximity sensor below one side of the belt conveyor assembly triggers and transmits a signal to the control panel. The control panel recognizes that the roller conveyor assembly has moved to its lowest position. When the roller conveyor assembly rises synchronously during rotation, a trigger on one side of the roller conveyor assembly corresponds to a proximity sensor above one side of the belt conveyor assembly. The proximity sensor above one side of the belt conveyor assembly triggers and transmits a signal to the control panel. The control panel recognizes that the roller conveyor assembly is at its highest position and controls the roller conveyor assembly to transport the material.

[0007] Optionally, the rotating mechanism includes a bearing seat disposed on the base, a rotating shaft disposed on the bottom surface of the main frame, the rotating shaft being rotatably sleeved inside the bearing seat, and a rotating drive mechanism for driving the rotating shaft to rotate around the bearing seat is disposed on one side of the bottom surface of the main frame.

[0008] By adopting the above technical solution, the rotary drive mechanism drives the rotary shaft to rotate inside the bearing seat, thereby driving the relative rotation between the main frame and the base.

[0009] Optionally, the outer surface of the bearing seat is provided with teeth in the circumferential direction, the rotary drive mechanism includes a motor, the output shaft of the motor is connected to a reducer, the output shaft of the reducer is connected to a drive gear, and the drive gear meshes with the teeth on the outer surface of the bearing seat.

[0010] By adopting the above technical solution, the motor in the rotary drive mechanism drives the gear to rotate through the reducer. The gear meshes with the teeth on the outer surface of the shaft seat, and the rotating shaft is driven to rotate inside the shaft seat through the action between the gear and the teeth.

[0011] Optionally, the belt conveyor assembly includes a belt mounting frame fixedly connected to the main frame. The two belt mounting frames are connected at both ends by a bracket. Rollers are provided at both ends of one side of the belt mounting frame. A conveyor belt is fitted on the two rollers. The rollers at one end of the two sets of belt conveyor assemblies are connected by a drive roller. A belt drive mechanism for driving the drive roller to rotate is provided below the drive roller.

[0012] By adopting the above technical solution, the belt drive mechanism drives two rollers to rotate through the drive roller, and the two rollers drive the belt to move to realize the conveying of materials.

[0013] Optionally, the roller conveying assembly includes a roller mounting frame on which a plurality of conveying rollers are rotatably mounted in parallel. The plurality of conveying rollers are connected to each other by a transmission chain. One end of the roller conveying assembly is provided with a roller drive mechanism for driving the conveying rollers to rotate.

[0014] By adopting the above technical solution, the roller drive mechanism drives one of the conveying rollers to rotate. Since the conveying rollers are connected by a transmission chain, several conveying rollers rotate synchronously to convey materials.

[0015] Optionally, the roller conveyor assembly is connected to the belt conveyor assembly at both ends via a lifting guide assembly. The lifting guide assembly includes bushings disposed at both ends of the belt conveyor assembly, and guide rods that cooperate with the bushings are disposed at both ends of the roller conveyor assembly. The guide rods are movably sleeved inside the bushings.

[0016] By adopting the above technical solution, the guide rod is driven to move up and down along the bushing during the lifting and lowering process of the roller conveyor assembly, thereby guiding the movement of the roller conveyor assembly through the guide rod and improving the stability of the lifting and lowering of the roller conveyor assembly.

[0017] Optionally, an auxiliary conveying component is provided on the side of each of the two sets of belt conveying assemblies away from the roller conveying assembly, and the auxiliary conveying component has the same conveying direction as the roller conveying assembly.

[0018] By adopting the above technical solution, auxiliary conveying components are set up to facilitate the feeding of materials into or out of the roller conveying components.

[0019] Optionally, the lifting assembly adopts a lifting rod, the upper end of which is fixedly connected to the bottom of the roller conveying assembly, the lower end of which extends into the lifting track, and a ball bearing is rotatably disposed inside the lower end of the lifting rod, allowing the lifting rod to move freely along the lifting track via the ball bearing.

[0020] By adopting the above technical solution, the lifting component uses a lifting rod. When the rotary conveyor rotates, the roller conveyor component drives the lifting rod to move. The lower end of the lifting rod moves along the lifting track. The balls roll inside the lifting track to reduce the friction between the lifting rod and the lifting track. As the height of the lifting track gradually increases, the lifting rod gradually lifts the roller conveyor component upward during the rotation process.

[0021] Optionally, the lifting assembly includes a cylinder, which is fixedly mounted on the bottom surface of the roller conveying assembly via a mounting base. A lifting block is connected below the cylinder via a piston rod, and ball bearings are rotatably disposed on the bottom surface of the lifting block.

[0022] By adopting the above technical solution, the lifting component uses a cylinder connected to the lifting block. When the material needs to be rotated and re-conveyed, the piston rod of the cylinder extends to drive the lifting block to move downward and contact the lifting track. During the rotation of the rotary conveyor, the cylinder and the lifting block move along the lifting track, lifting the roller conveyor component as the rotary conveyor rotates. When the rotary conveyor is used as a reversing conveyor, that is, to change the conveying direction of the material, the cylinder is driven, the piston rod of the cylinder retracts, and the piston rod drives the lifting block to move upward. The lifting block disengages from the lifting track. During the rotation of the rotary conveyor, the lifting block does not contact the lifting track, so the roller conveyor component cannot be lifted. The material is always placed on the belt conveyor component. After the rotary conveyor rotates a certain angle, the belt conveyor component runs and conveys the material to the conveyor belt in another direction. Thus, by controlling the cylinder to drive the lifting block, different functions of the rotary conveyor can be achieved.

[0023] Optionally, baffles are provided at both ends of the lifting track, and proximity sensors are also provided at the upper end of the baffles.

[0024] By adopting the above technical solution, when the rotary conveyor is used as a reversing conveyor, the lifting block is positioned above the lifting track under the action of the cylinder. At this time, the position of the lifting block corresponds to the position of the proximity sensor on the baffle. In the initial state, the lifting block triggers the proximity sensor at the lower end of the lifting track. After the rotary conveyor rotates, the lifting block triggers the proximity sensor at the higher end of the lifting track, which makes it easier for the control system to identify the state of the rotary conveyor and perform automated control.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. In this application, the lifting assembly adopts an arc-shaped lifting guide rail and a lifting component. The lifting component is set at the bottom of the roller conveyor assembly. During the rotation of the roller conveyor assembly, the lifting component moves along the arc-shaped lifting guide rail to lift the roller conveyor assembly, which effectively realizes the synchronous rotation and lifting of the roller conveyor assembly. Moreover, the structure is simple and the disassembly and maintenance are convenient.

[0027] 2. In this application, a liftable roller conveyor is installed in the middle of the belt conveyor assembly. The roller conveyor moves up and down synchronously during rotation. After the material enters the belt conveyor assembly from the conveyor belt, the roller conveyor rises and lifts the material as the main frame rotates. Then, the material is conveyed to the conveyor belt through the roller conveyor assembly, realizing the rotation of the material angle. Then, the next material enters the roller conveyor assembly through the conveyor belt. The roller conveyor assembly rotates in the opposite direction to reset. After the material rotates a certain angle, it enters the belt conveyor assembly, which then conveys the material to the conveyor belt. This effectively realizes automated and continuous angle rotation and conveying of materials, greatly improving the efficiency of material rotation and conveying. Moreover, the device has a simple structure and is easy to operate.

[0028] 3. In this application, the lifting component adopts a structure in which a cylinder connects to the lifting block. The lifting component is controlled by the cylinder driving the lifting block to raise and lower. When the lifting component is closed, the roller conveyor component no longer rises during the rotation of the rotary conveyor. The rotary conveyor can then be used as a reversing conveyor to transport materials to a conveyor belt in another direction. When the lifting component is open, the roller conveyor component is lifted upwards during the rotation of the rotary conveyor. The rotary conveyor can then reverse the direction of the materials for further transport, thus expanding the functionality and applicability of the rotary conveyor. Attached Figure Description

[0039] The following is combined with Figure 1-9 This application is described in further detail.

[0040] Example 1:

[0041] This embodiment discloses a multifunctional rotary conveyor device.

[0042] Reference Figure 1 A multifunctional rotary conveying device includes a base 7, a main frame 1, and two sets of belt conveyor assemblies 2. The two sets of belt conveyor assemblies 2 are symmetrically fixed above the main frame 1. Auxiliary conveyor assemblies 6 are provided on both sides of the two sets of belt conveyor assemblies 2.

The bottom of the roller conveyor assembly 3 is connected to the base 7 through a lifting assembly 5. The lifting assembly 5 drives the roller conveyor assembly 3 to reciprocate up and down during the rotation of the main frame 1.

[0043] Reference Figure 2 and Figure 4 The lifting assembly 5 includes three arc-shaped lifting tracks 9 set on the base 7. The height of the lifting tracks 9 gradually increases along the circumferential direction. The bottom of the roller mounting frame 21 in the roller conveying assembly 3 is connected to three evenly spaced lifting components 8. The lifting components 8 adopt lifting rods.

[0044] Reference Figure 3 , Figure 4 and Figure 6 The rotating mechanism 4 includes a rotating shaft 13 located at the center of the bottom surface of the main frame 1. A bearing seat 12 is located in the middle of the base 7. The rotating shaft 13 is rotatably sleeved in the middle of the bearing seat 12. A rotating drive mechanism 19 is located on one side of the rotating shaft 13 on the bottom surface of the main frame 1. The rotating drive mechanism 19 includes a motor fixedly installed on the bottom surface of the main frame 1. A reducer is connected to the output shaft of the motor. A drive gear 10 is connected to the reducer through the output shaft. Teeth are arranged circumferentially on the outer surface of the bearing seat 12. The drive gear 10 meshes with the teeth.

[0045] Reference Figure 5 and Figure 6 Two sets of belt conveyor assemblies 2 are provided, and the two sets of belt conveyor assemblies 2 are symmetrically arranged and connected at both ends by brackets 18. The belt conveyor assembly 2 includes a belt mounting frame 14 fixedly connected to the main frame 1. Rollers are provided at both ends of one side of the belt mounting frame 14, and a conveyor belt 17 is sleeved on the two rollers. The rollers at one end of the two belt mounting frames 14 are connected to each other by a drive roller 15. A belt drive mechanism 16 is provided below the drive roller 15. The belt drive mechanism 16 includes a motor fixedly mounted on the bracket 18. The output shaft of the motor is connected to a reducer. The output shaft of the reducer is connected to the drive roller 15 through a belt drive mechanism.

[0046] Reference Figure 3 and Figure 7The roller conveying assembly 3 includes a roller mounting frame 21, which is movably mounted above the main frame 1. Both ends of the roller mounting frame 21 are connected to the support 18 via a lifting guide assembly 20. The lifting guide assembly 20 includes a bushing 23 mounted on the support 18. Guide rods 24 are provided at both ends of the roller mounting frame 21, and the guide rods 24 are movably fitted inside the bushing 23. Multiple parallel conveying rollers 22 are rotatably mounted on the roller mounting frame 21. One end of the multiple conveying rollers 22 is connected by a transmission chain. A roller drive mechanism 11 is provided at one end of the roller mounting frame 21. The roller drive mechanism 11 includes a motor fixedly connected to the roller mounting frame 21. The output shaft of the motor is connected to a reducer. The output shaft of the reducer is connected to the conveying rollers 22 via a transmission chain. A sensor assembly is also provided on one side of the roller mounting frame 21. The sensor assembly includes two proximity sensors 25 arranged vertically. The two proximity sensors 25 are fixedly mounted on the support 18 via a mounting plate 27. A trigger 26 is provided on one side of the roller mounting frame 21 corresponding to the proximity sensors 25.

[0047] The implementation principle of the multifunctional rotary conveying device in this embodiment is as follows: The rotary conveying mechanism is set in the middle of the conveyor belt. The conveying direction of the belt conveyor assembly 2 is consistent with the conveying direction of the conveyor belt. In the initial state, the roller conveyor assembly 3 is located at the bottom. The material is conveyed to the belt conveyor assembly 2 via the conveyor belt. The belt drive mechanism 16 in the belt conveyor assembly 2 drives the conveyor belt 17 to move through the drive roller 15, conveying the material to the middle position of the rotary conveying mechanism. Then, the rotary drive mechanism 19 in the rotary conveying mechanism is started. The motor in the rotary drive mechanism 19 is driven by the reducer. The rotating gear 10 rotates, meshing with the teeth on the outer side of the shaft seat 12. This meshing of the gear 10 and the teeth drives the rotating shaft 13 to rotate inside the shaft seat 12, causing the main frame 1 and the base 7 to rotate relative to each other. The main frame 1 drives the belt conveyor assembly 2 and the roller conveyor assembly 3 to rotate synchronously. During rotation, the guide rod 24 on the bottom surface of the roller mounting bracket 21 moves synchronously along the lifting track 9. As the height of the lifting track 9 gradually increases, the roller conveyor assembly 3 gradually rises during rotation. When the main frame 1 rotates 90 degrees, the roller conveyor assembly 3 reaches its highest point. The material is now rotated 90 degrees and is positioned on the roller conveyor assembly 3. After rotating 90 degrees, the roller conveyor assembly 3 is connected to the conveyor belt. The trigger 26 on one side of the roller mounting bracket 21 moves upward and corresponds to the proximity sensor 25 above the bracket 18. The proximity sensor 25 is triggered, and the control system drives the roller drive mechanism 11 in the roller conveyor assembly 3 to operate. The roller drive mechanism 11 drives the conveyor roller 22 to rotate, and the conveyor roller 22 conveys the rotated material to the conveyor belt, which then conveys it to the next process. At the same time, the conveyor belt conveys the next piece of material to the roller conveyor assembly 3. After the roller conveyor assembly 3 conveys the material to the middle of the rotary conveyor, the rotary drive mechanism 19 drives the main frame 1 to rotate in the opposite direction to reset. At this time, the rotary conveyor rotates the material 90 degrees in the opposite direction. The roller conveyor assembly 3 descends during the reverse rotation, and the material is placed on the belt conveyor assembly 2. After the roller conveyor assembly 3 resets to the bottom, the proximity sensors 25 above and below the bracket 18 are triggered, and the control system controls the belt drive mechanism 16 to run. The belt drive mechanism 16 drives the belt conveyor assembly 2 to convey the material into the conveyor belt. Then the above operation is repeated to realize the automated rotary conveying of the material.

[0048] Example 2:

[0049] Reference Figure 8 and Figure 9 The difference between this embodiment and the first embodiment is that the lifting assembly 8 in this embodiment includes a cylinder 30. The cylinder 30 is fixedly installed on the bottom surface of the roller mounting frame 21 through the mounting base 29. The cylinder 30 is connected to the lifting block 32 through the piston rod 31. The bottom surface of the lifting block 32 is rotatably provided with a ball bearing 33. Both ends of the lifting track 9 are provided with baffles 28, and the upper end of the baffles 28 is provided with a proximity sensor 25.

[0050] The implementation principle of the multifunctional rotary conveying device in this embodiment 2 is as follows: The lifting component 8 is connected to the lifting block 32 by a cylinder 30. When it is necessary to rotate the material for further conveying, the piston rod 31 of the cylinder 30 extends to drive the lifting block 32 to move downward and contact the lifting track 9. During the rotation of the rotary conveying device, the cylinder 30 and the lifting block 32 move along the lifting track 9 through the ball bearings 33. As the rotary conveying device rotates, it lifts the roller conveying component 3 upward, thereby realizing the rotation and conveying of the material. When the rotary conveying device is used as a reversing conveying device, that is, used to change the conveying direction of the material, the cylinder 30 is driven, the piston rod 31 of the cylinder 30 retracts, and the piston rod 31 drives the lifting block 32 to move upward. Under the action of the cylinder 30, the lifting block 32 is positioned at the lifting position. Above the lowering track 9, the position of the lifting block 32 corresponds to the position of the proximity sensor 25 on the baffle 28. In the initial state, the lifting block 32 triggers the proximity sensor 25 at the lower end of the lifting track 9. When the rotary conveyor rotates, the lifting block 32 does not contact the lifting track 9 during the rotation process, so the roller conveyor assembly 3 cannot be lifted and the material is always placed on the belt conveyor assembly 2. After the rotary conveyor rotates a certain angle, the lifting block 32 triggers the proximity sensor 25 at the higher end of the lifting track 9. The control system controls the belt conveyor assembly 2 to run, and the belt conveyor assembly 2 transports the material to the conveyor belt in another direction. Thus, by controlling the cylinder 30 to drive the lifting block 32, different functions of the rotary conveyor can be realized.

[0051] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
