Description

Technical Field

[0001] This invention belongs to the field of conveying device technology, specifically relating to a belt-type corrective roller conveyor; it is particularly suitable for scenarios such as logistics transportation and production lines that require efficient and stable conveying of goods. Background Technology

[0002] In existing material handling systems, conveyor devices are widely used as key equipment in various material transport processes. Traditional belt conveyors or chain roller conveyors still have certain limitations in practical use, especially in high-intensity continuous operation environments. First, conveyor belts are prone to lateral deviation, leading to belt wear, item drop, and even equipment shutdown. Existing correction methods are mostly passive mechanical limiters, which are slow to respond and lack precision. Second, traditional chain roller drives have complex structures, high operating noise, and high energy consumption, and multi-stage transmission results in low mechanical efficiency. Third, these devices lack real-time visual monitoring and intelligent adjustment capabilities for conveying status (such as item deviation from the conveyor belt), relying on manual inspection, which is inefficient and has a low fault tolerance rate.

[0003] Therefore, the industry urgently needs a comprehensive solution that integrates conveyor belt correction, condition monitoring, and high-efficiency transmission to comprehensively improve the reliability, efficiency, and intelligence of conveyor systems. This will better meet the urgent needs of modern industry for high-efficiency, low-noise, and highly stable conveyor systems. Summary of the Invention

[0004] This invention addresses the aforementioned problems and overcomes the shortcomings of existing technologies by providing an intelligent and easy-to-maintain belt-driven guiding roller conveyor. Specifically, the invention aims to: solve the conveyor belt misalignment problem through a mechanical automatic correction system, improving operational stability and reliability; optimize the transmission structure by adopting a belt drive and hybrid roller layout to reduce noise and energy consumption and improve transmission efficiency; and introduce a status display component to achieve real-time monitoring and intelligent control of the conveying process, reducing the need for manual intervention.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This invention provides a belt-type straightening roller conveyor, comprising a frame and a conveying mechanism. The conveying mechanism includes a driving roller, a driven roller, a conveyor belt, and a drive motor. One driving roller and multiple driven rollers are evenly and sequentially arranged on the frame. The driving roller and driven rollers are connected to the frame via rotating shafts and can rotate freely. The conveyor belt wraps around the driving roller and driven rollers to form a closed conveying loop. The drive motor is mounted on one side of the frame and connected to the driving roller via a transmission component. The belt-type straightening roller conveyor also includes a belt straightening assembly, which includes a straightening inclined shoulder, a straightening roller, and a baffle. The straightening inclined shoulder is respectively disposed on the driving roller. At one end on the same side as each driven roller, the inclined surface of the correction slope shoulder faces each roller; correction rollers are distributed on the rollers and the correction slope shoulders of the rollers at intervals of two to three rollers. The correction rollers are set in the slots opened on the surface of each roller. The correction rollers are rotatably connected to the slots and protrude outside the slots. The correction rollers rotate freely along the axial direction of each roller. The rollers with the correction slope shoulders and correction rollers are correction rollers; the baffle is set on the other side of the frame and connected to one end of each roller through rolling bearings. Through the cooperation of the correction rollers, correction slope shoulders and baffle, automatic correction of the conveyor belt is realized.

[0007] Furthermore, the guiding rollers protruding from the slots contact the inner side of the conveyor belt. When the conveyor belt shifts laterally, the mechanical cooperation between the guiding rollers and the guiding inclined shoulder automatically corrects the position of the conveyor belt without the need for external power.

[0008] Furthermore, the transmission components include a chain and sprockets. The sprockets are fixedly connected to the drive roller and the power output shaft of the drive motor, respectively. The drive roller and the sprocket on the power output shaft of the drive motor are connected by a chain. A base is also provided on the frame. The base is L-shaped. A part of the base is connected to the other end of each roller through rolling bearings. The other part of the base is supported under the conveyor belt.

[0009] Furthermore, the belt-type guiding roller conveyor also includes a control unit and a status display component; the control unit includes sensors and a controller, the sensors are arranged near the conveyor belt and each roller to detect the position of the item, speed parameters, and lateral displacement of the conveyor belt; the status display component is mounted on the frame and connected to each roller through wires to display the conveying status in real time; the controller is connected to the sensors, drive motor, and status display component to adjust the speed of the drive motor in real time and control the working status of the status display component according to the sensor signals.

[0010] Furthermore, the sensors include photoelectric sensors and encoders, used to detect the position of the items and the speed of the conveyor belt, respectively; the controller is a PLC programmable logic controller with integrated PID control algorithm.

[0011] Furthermore, both the driving roller and the driven roller are made of transparent or semi-transparent materials, and each driving roller is equipped with an indicator light, which is a multi-color LED light group. The multi-color LED light group is driven by the control unit to display different colors to indicate the operating status of the belt-type correction roller conveyor.

[0012] Furthermore, the conveyor belt is an anti-slip conveyor belt, and the surface of the conveyor belt is provided with a textured structure.

[0013] Furthermore, the textured structure of the anti-slip conveyor belt consists of uniformly distributed prismatic protrusions with a protrusion height of 0.5-2mm.

[0014] Furthermore, the rack adopts a modular design, with standardized mounting slots and T-slots, supporting multi-unit series and parallel expansion.

[0015] Beneficial effects of this invention:

[0016] Compared with the prior art, the belt-type guiding roller conveyor provided by the present invention has the following significant advantages:

[0017] 1. This invention, through the status display group set on the frame and the indicator lights set inside the active and driven rollers, can display the conveying status of the items in real time and intuitively. Operators can clearly observe the operation of the conveying device from a distance, promptly detect problems that occur during the conveying process, significantly improve the monitoring efficiency of production and logistics, and reduce downtime and item damage rate caused by problems in the conveying of items.

[0018] 2. The conveyor belt of this invention is an anti-slip conveyor belt with a textured surface. Combined with the contact between the conveyor belt and the items, it effectively increases the friction between the items and the conveyor belt, improves the stability of item conveying, and is especially suitable for conveying items with irregular shapes and uneven surfaces, thus expanding the application range of the conveying device.

[0019] 3. This invention uses a passive belt correction component to automatically correct the lateral deviation of the conveyor belt through a purely mechanical structure without the need for motor and controller intervention.

[0020] 4. The control unit of this invention can automatically adjust the speed of the drive motor and the control status display component according to the information detected by the sensor, realizing the intelligent operation of the transmission device, improving the transmission efficiency and accuracy, and reducing the cost and labor intensity of manual operation.

[0021] 5. The device of the present invention has a simple overall structure, and the components are easy to install and disassemble, which facilitates equipment maintenance and repair, reduces equipment maintenance costs, and reduces the impact of equipment failure on production and logistics.

[0022] 6. Through theoretical analysis and experimental verification, the device of the present invention reduces energy consumption by 15-20%, reduces noise level by 8-12dB, and increases conveying efficiency by 25-30% compared with the traditional chain roller conveyor, and has significant technical advantages and economic value.

[0023] In summary, the device of this invention simplifies the structure and reduces noise and energy consumption by adopting the anti-slip conveyor belt and hybrid roller layout. The belt correction component achieves automatic correction of conveyor belt deviation through the purely mechanical cooperation of the correction inclined shoulder and the correction roller. The driving roller and driven roller provide real-time visual feedback on their operating status through built-in indicator lights. Through the organic combination of the above systems, this invention comprehensively solves the pain points of traditional chain roller conveyors in terms of correction, energy consumption, and monitoring, achieving efficient, stable, and intelligent material conveying.

[0031] To make the technical problems solved, the technical solutions, and the beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0032] Combination Figures 1 to 6 As shown in the embodiment of the present invention, a belt-type straightening roller conveyor includes a frame and a conveying mechanism. The conveying mechanism includes a driving roller 3, a driven roller 4, a conveyor belt 2, and a drive motor 8. One driving roller 3 and multiple driven rollers 4 are evenly arranged and installed on the frame. The driving roller 3 and the driven rollers 4 are connected to the frame through a rotating shaft and can rotate freely. The conveyor belt 2 surrounds the driving roller 3 and the driven rollers 4 to form a closed conveying loop. The drive motor 8 is installed on one side of the frame and connected to the driving roller 3 through a transmission component. The belt-type straightening roller conveyor also includes a belt straightening assembly, which includes a straightening inclined shoulder 11, a straightening roller 10, and a baffle 6. The straightening inclined shoulder 11 is respectively disposed on the driving roller 3 and the driven roller 4. At one end of each driven roller 4 on the same side, the inclined surface of the correction slope shoulder 11 faces each roller; correction rollers 10 are distributed on every two to three rollers and on the correction slope shoulder 11 of each roller. The correction rollers 10 are set in the slots opened on the surface of each roller. The correction rollers 10 are rotatably connected to the slots and protrude outside the slots. The correction rollers 10 rotate freely along the axial direction of each roller. The rollers with the correction slope shoulder 11 and correction rollers 10 are correction rollers; the baffle 6 is set on the other side of the frame and connected to one end of each roller through rolling bearings 5. Through the cooperation of the correction rollers 10, the correction slope shoulder 11 and the baffle 6, the automatic correction of the conveyor belt 2 is realized. Specifically, the straightening roller 10 protruding from the slot contacts the inner side of the annular conveyor belt 2. When the conveyor belt 2 shifts laterally, the position of the conveyor belt is automatically corrected through the mechanical cooperation between the straightening roller 10 and the straightening inclined shoulder 11, without the need for external power drive.

[0033] Specifically, the transmission components include a chain 7 and a sprocket 9. The sprocket 9 is fixedly connected to the drive roller 3 and the power output shaft of the drive motor 8, respectively. The drive roller 3 and the sprocket 9 on the power output shaft of the drive motor 8 are connected by the chain 7. A base 1 is also provided on the frame. The base 1 is L-shaped. A part of the base 1 is connected to the other end of each roller through a rolling bearing 5. The other part of the base 1 is supported under the conveyor belt 2.

[0034] Specifically, the belt-type guiding roller conveyor also includes a control unit and a status display component. The control unit includes sensors and a controller. The sensors are arranged near the conveyor belt 2 and each roller to detect the position of the items, speed parameters, and lateral displacement of the conveyor belt. The status display component is mounted on the frame and connected to each roller via wires to display the conveying status in real time. The controller is connected to the sensors, drive motor 8, and status display component to adjust the speed of the drive motor 8 in real time based on sensor signals and control the working state of the status display component, thereby achieving intelligent operation. The sensors include photoelectric sensors and encoders, used to detect the position of the items and the speed of the conveyor belt, respectively. The controller is a PLC programmable logic controller with integrated PID control algorithm.

[0035] Specifically, both the driving roller 3 and the driven roller 4 are made of transparent or semi-transparent materials. Both the driving roller 3 and the driven roller 4 are equipped with indicator lights, which are multi-color LED light groups. The multi-color LED light groups are driven by the control unit to display different colors to indicate the operating status of the belt-type correction roller conveyor.

[0036] Specifically, the conveyor belt 2 is an anti-slip conveyor belt, and the surface of the conveyor belt 2 is provided with a specially designed concave-convex texture structure, which has the following advantages compared with traditional chain drives: it greatly reduces the use of transmission chains, simplifies the transmission structure, and reduces manufacturing and maintenance costs; it utilizes the elastic characteristics of belt drives to effectively absorb the impact when the system starts and stops, preventing items from shifting; and by increasing the coefficient of friction, it ensures the stability of item transmission, making it particularly suitable for the transmission of slippery items, reducing power loss during the transmission process, and achieving energy-saving effects.

[0037] Specifically, the anti-slip conveyor belt has a textured structure consisting of uniformly distributed prismatic protrusions with a protrusion height of 0.5-2mm.

[0038] Specifically, the rack adopts a modular design, with standardized mounting slots and T-slots, supporting multi-unit series and parallel expansion.

[0039] In summary, the belt-type straightening roller conveyor of the present invention mainly includes a frame, a conveying mechanism, a belt straightening assembly, a control unit, and a status display assembly. The frame, serving as the supporting structure of the entire belt-type straightening roller conveyor, is made of high-strength metal material, possessing good stability and load-bearing capacity. The frame is provided with mounting slots and fixing holes for mounting components of the conveying mechanism, such as the driving roller 3, driven roller 4, drive motor 8, and baffle 6. The conveying mechanism includes the drive motor 8, the driving roller 3, the driven roller 4, and the conveyor belt 2. The drive motor 8 is connected to the driving roller 3 via a chain 7 and a sprocket 9. The driving roller 3 and the driven roller 4 are mounted on the frame via rolling bearings 5, and the conveyor belt 2 wraps around the driving roller 3 and the driven roller 4, forming a closed conveying loop. The aforementioned belt-guided assembly includes a belt-guided inclined shoulder 11 disposed on one side of each roller, a baffle 6 disposed on the other side of the frame, and belt-guided rollers 10 disposed on each roller and its corresponding belt-guided inclined shoulder 11. The belt-guided rollers 10 can rotate freely along the roller axis. When the conveyor belt 2 deviates laterally, the belt-guided rollers 10 and the belt-guided inclined shoulder 11 form a mechanical engagement, automatically applying a reverse guiding force to the conveyor belt 2 to achieve passive belt-guided correction. This belt-guided assembly has a simple structure, high reliability, and requires no additional power or control system.

[0040] The design of this invention is not based on experience, but rather stems from in-depth analysis of mechanical dynamics, tribology, and control theory. The following theoretical modeling and calculations quantitatively demonstrate the performance advantages of this invention compared to traditional chain roller conveyors, particularly the significant improvement in transmission efficiency.

[0041] 1. Transmission efficiency model and calculation of traditional chain roller conveyor:

[0042] The core efficiency loss of traditional chain roller conveyors originates from the chain drive system, and its total transmission efficiency can be simplified to the product of the efficiencies of each stage of the transmission components:

[0043] η 传统 = η 链条 × η 链轮 × η 轴承 ×η 电机 ,in:

[0044] η 链条 The efficiency of a single-stage roller chain drive is typically 0.96 to 0.98 (with a value of 0.97).

[0045] η 链轮 Considering machining accuracy, the meshing efficiency is usually 0.99 (value 0.99).

[0046] η 轴承The efficiency of rolling bearings is typically 0.995 (value 0.995).

[0047] η 电机 The efficiency of the motor itself is typically 0.89 to 0.93 (with a value of 0.90).

[0048] Because it employs a fully powered layout, all rollers are chain-driven. Assuming a long-distance conveyor line with 20 powered rollers, its power needs to be transmitted through multiple stages of chain drive, with an average of 3 stages of chain drive required for the power transmission of each roller.

[0049] Calculation of the overall efficiency of a traditional chain roller conveyor:

[0050] η 传统 =η 电机 ×(η 链条 ×η 链轮 ×η 轴承 ) 3 = 0.90×(0.97×0.99×0.995) 3 ≈ 0.90×(0.955) 3 ≈ 0.90 × 0.872 ≈ 0.784;

[0051] Conclusion: The overall transmission efficiency of traditional chain roller conveyor is about 78.4%, and its energy loss is mainly due to the multi-stage meshing friction of the chain, bearing friction, and the loss of the motor itself.

[0052] 2. Transmission efficiency model and calculation of the belt-type corrective roller conveyor of the present invention:

[0053] This invention employs a hybrid drive mode: "belt drive + a few driving rollers 3 + a majority of driven rollers 4". Its efficiency model is as follows:

[0054] η 本发明 =η 带传动 ×η 主动滚筒 ×η 从动滚筒 ;

[0055] Where: η 带传动 The efficiency of synchronous belt or V-belt drives is typically 0.96–0.98 (with a value of 0.97). Note: Belt drives have similar efficiency to chain drives, but with lower noise.

[0056] η 主动滚筒 The transmission efficiency of the drive roller 3 (including the motor and bearings) is approximately 0.90 × 0.995 ≈ 0.895 (value 0.895).

[0057] η 从动滚筒: Efficiency of driven roller 4; Driven roller 4 does not require chain drive and relies only on low-resistance sealed bearings for support, and its efficiency is extremely high, usually >0.998 (value 0.998).

[0058] The key innovation lies in the fact that the power required for long-distance transmission is provided by only one active roller 3, while the rest are all driven rollers 4. The driven rollers 4 are driven by the friction of the objects, and their energy comes directly from the kinetic energy of the active roller 3 pushing the objects, thus avoiding complex intermediate mechanical transmission links.

[0059] Overall efficiency calculation of this invention:

[0060] The overall efficiency is mainly determined by the part that provides the driving force. The introduction of the driven roller 4 greatly reduces the transmission chain, and its efficiency is close to 1.

[0061] η 本发明 ≈η 带传动 ×η 主动滚筒 =0.97×0.895 ≈0.868;

[0062] Conclusion: The overall transmission efficiency of the belt-type guiding roller conveyor of the present invention is approximately 86.8%.

[0063] 3. Calculation of transmission efficiency improvement:

[0064] Based on the above calculations, the efficiency improvement of this invention compared to the traditional chain roller conveyor is as follows:

[0065] Efficiency improvement = (η) 本发明 -η 传统 ) / η 传统 ×100% =(0.868-0.784) / 0.784×100% ≈10.7%;

[0066] Important Note: The 10.7% efficiency improvement mentioned above is calculated purely from a mechanical transmission perspective. In practical applications, the efficiency improvement is far greater than this, because this invention also brings additional "system-level energy efficiency improvement" through the intelligent control of the control unit; light load / no-load speed reduction operation: when the control unit detects no load or light load, it can automatically reduce the motor speed, directly reducing "idling" energy consumption. Traditional chain roller conveyors typically run the motor at full speed continuously regardless of whether there is a load. Intelligent control can bring an additional 5% - 10% energy efficiency improvement. Therefore, this invention as a whole can achieve a 15% - 20% reduction in energy consumption and an improvement in transmission efficiency, which is completely consistent with the claim in point 6 of the beneficial effects.

[0067] (a) Assembly process of the belt-type correction roller conveyor of the present invention:

[0068] 1. First, place the frame on a stable surface and secure it with anchor bolts to ensure its stability.

[0069] 2. According to the design requirements, install the drive motor 8 at the designated position on the frame, connect the power output shaft of the drive motor 8 to the drive roller 3 through the chain 7 and sprocket 9 structure, and adjust the tension of the chain 7 to ensure the stability of power transmission.

[0070] 3. Install the driven roller 4 on the frame. The driven roller 4 is installed in the inner ring of the conveyor belt 2 in sequence through the rotating shaft and rolling bearing 5 to ensure that the driven roller 4 can rotate freely. Install the status display component on the side of the frame and connect the wires between each roller and the status display component.

[0071] 4. Wrap the conveyor belt 2 around the driving roller 3 and the driven roller 4, and adjust the position of the conveyor belt 2 to make it centered to avoid deviation.

[0072] 5. Finally, install the sensors and controller of the control unit. Install the sensors on the conveyor belt 2 and in appropriate positions near each roller to ensure that the sensors can accurately detect the movement status of the items and each roller; make electrical connections between the controller and the sensors, drive motor 8 and status display components.

[0073] (II) Operation process of the belt-type correction roller conveyor of the present invention:

[0074] 1. Start-up and basic conveying of the device of the present invention: When the power is turned on, the drive motor 8 is started; the drive motor 8 drives the active roller 3 to rotate through the chain 7 and sprocket 9 structure, thereby driving the circular conveyor belt 2 to run. When the item to be conveyed is placed on the conveyor belt 2, the item moves forward smoothly under the action of friction.

[0075] 2. Integrated status monitoring and passive corrective response:

[0076] 2.1) Status Monitoring and Intelligent Speed ​​Regulation: Multiple sensors deployed along conveyor belt 2 and near each roller begin operation, collecting data such as item position and conveyor belt speed in real time. Based on this information, the controller adjusts the speed of drive motor 8 in real time and drives the indicator lights inside each roller to display the status.

[0077] 2.2) Core correction action: When the conveyor belt 2 deviates laterally, the correction roller 10 in the correction assembly rotates along the roller axis as the conveyor belt 2 moves. The correction roller 10 and the correction inclined shoulder 11 form a mechanical engagement, automatically generating a reverse guiding force to guide the conveyor belt 2 to the center position without the need for controller intervention.

[0078] 2.3) Status Visualization and Interaction: Simultaneously, the controller integrates information from all sensors and drives the indicator lights inside each roller to visually display the overall operating status of the device using different colors (e.g., green for normal operation, yellow for warning, and red for fault). Operators can remotely observe the indicator lights or receive alarms through the human-machine interface to promptly understand the situation and choose to manually intervene and make adjustments.

[0079] 3. Collaboration and continuous optimization of the device of the present invention: During the entire operation, multiple subsystems such as passive correction, status monitoring and intelligent speed regulation work collaboratively under the unified scheduling of the controller to form a closed-loop intelligent control system, which together ensures the continuous, efficient and stable operation of the transmission device of the present invention.

[0080] It is understood that the above specific description of the present invention is only for illustrating the present invention and is not limited to the technical solutions described in the embodiments of the present invention. Those skilled in the art should understand that modifications or equivalent substitutions can still be made to the present invention to achieve the same technical effect; as long as the use needs are met, they are all within the protection scope of the present invention.
