[0002] The assembly line reversing mechanism is a complex and important field. It is installed at the connection of two mutually perpendicular roller conveyor lines to achieve right-angle reversal of the wheels on the conveyor line. Because the roller conveyor lines in the wheel production automatic line need to turn according to actual conditions, the wheels need to achieve right-angle reversal of movement direction from one line to the other. Without any device between the two roller lines, the wheels will get stuck in the middle when moving to the connection position. If a cylinder is used to push hard, not only will the rollers be easily worn, reducing the life of the conveyor line, but the wheels will also be easily scratched, reducing product quality. Therefore, a wheel product reversing device in the roller conveyor line is needed to solve this problem.

The conveyor line is provided on the top surface of the lifting platform. The conveying direction of the conveyor line is consistent with the conveying direction of the second conveyor line, and the discharge end of the conveyor line is opposite to the feed end of the second conveyor line.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] The following describes a complete embodiment of the present invention: The upper base plate (6) is located at the top of the entire reversing mechanism. The upper base plate fixes several pulley modules (3) to provide support for the reversing of the material. The motor is the power source of the reversing mechanism and realizes the reversing of the material by driving the pulley module. The pulley module is the core component of the reversing mechanism and is equipped with a top pulley (16), an axial pulley (18) and a pressure wheel (4). The pulley module is driven by a transmission belt (15) to realize the reversing of the material. The transmission belt connects the pulley module (3) and transmits power to the pulley module through the driving force of the motor (1). The top pulley is fixed on the transmission shaft (2) and cooperates with the axial pulley (18) to realize the reversing of the material. The axial pulley is fixed on the transmission shaft (2) and cooperates with the top pulley (16) to realize the reversing of the material.

[0022] The pressure wheel is pressed by the slider (12) to ensure the stability of the pulley module. The slider can move up and down, and fix the pressure wheel (4) by pressing the locking column (17) to ensure the stability of the pulley module. Several fixed seat bearings (5) are fixed on the transmission long shaft to provide support for the pulley module. The fixed seat bearings are fixed on the transmission long shaft to provide support for the pulley module. The upper base plate (6) and the lower base plate (7) are connected by a fixed flange to ensure the stability of the mechanism. The lower base plate is connected to the jacking device (9) to provide support for the entire reversing mechanism. The jacking device is used to adjust the height of the assembly line to adapt to materials of different heights. The linear bearing is connected under the lower base plate (7) to reduce friction and improve the operating efficiency of the reversing mechanism.

[0023] The guide column is used to fix the linear bearing (10) to ensure its stability during operation. It is preferably designed as a triangular structure to improve stability. The pressure wheel (4) is against the side of the axial pulley (18) to achieve a better clamping effect. The internal fixed locking column (17) and the slider (12) can move up and down to clamp the locking column (17) to adjust the clamping force. Several fixed seat bearings (5) are fixed on the transmission shaft to improve the stability of the pulley module. The upper base plate (6) and the lower base plate (7) are connected by a fixed flange (11) to improve the stability of the entire mechanism. The linear bearing (10) is fixed by the guide column (8) to reduce friction and improve the operating efficiency of the reversing mechanism.

[0024] according to Figures 1 to 4 , a complete description of the connection relationship of this embodiment: The upper base plate (6) is the supporting structure of the entire reversing mechanism and is usually made of strong steel to bear the weight of the material and the pulley module (3). The pulley module (3) is fixed to the upper base plate (6) through precisely machined holes and bolts. The bolts are usually equipped with anti-loosening washers to prevent loosening due to vibration during operation. The distribution design of the pulley module (3) takes into account the direction of material flow and load distribution to ensure a smooth transition of the material during the reversing process.

[0025] The motor (1) is typically a variable frequency motor to achieve precise control of the rotational speed, thereby controlling the reversing speed of the material. The coupling between the motor (1) and the transmission belt (15) can be rigid or elastic to accommodate small misalignment between the motor and the transmission belt. In the case of a belt drive, the tension of the belt can be adjusted by adjusting the position of the motor to ensure transmission efficiency and reduce slippage.

[0026] The transmission belt (15) can be a chain, a belt or a gear, and the appropriate transmission mode is selected according to the weight of the material and the reversing speed requirement. The meshing design of the transmission belt (15) and the top pulley (16) ensures the effective transmission of power while leaving enough gap to reduce wear.

[0027] The top pulley (16) is mounted on the transmission shaft (2) through a bearing. The type and size of the bearing are selected according to the load and speed requirements. The transmission shaft (2) needs to be lubricated regularly to reduce friction and extend its service life.

[0028] The axial pulley (18) is connected to the transmission shaft (2) in a similar manner to the top pulley (16), but may have different bearing configurations to accommodate different load and direction requirements.

[0029] The design of the pressure wheel (4) ensures the stability of the pulley module (3) during operation and prevents displacement due to material impact. The slider (12) moves up and down in the pulley module (3) through a precise guide rail system. The guide rail can be straight or curved to meet different compression requirements.

[0030] The connection mode between the slider (12) and the locking column (17) can be threaded or wedge-shaped to adapt to different pressing force and speed requirements. The design of the locking column (17) takes into account the strength and wear resistance of the material to ensure long-term stable operation.

[0031] The fixed seat bearing (5) provides a stable support point for the transmission long shaft (2) to prevent bending or deviation due to load or vibration. The installation position and number of the fixed seat bearing (5) are determined according to the length and load requirements of the transmission long shaft (2).

[0032] The fixing flange (11) is a key component connecting the upper base plate (6) and the lower base plate (7), and is usually made of high-strength steel. The bolt holes on the fixing flange (11) need to be precisely aligned to ensure the flatness and stability of the upper and lower base plates.

[0033] The connection between the lower base plate (7) and the lifting device (9) must be able to withstand the load and torque during the lifting process. The lifting device (9) is designed with ease and safety in mind and may include limit switches and an emergency stop button. The linear bearing (10) is designed to allow the lower base plate (7) to move smoothly in the vertical direction to accommodate materials at different heights. The linear bearing (10) must be precisely aligned to reduce friction and wear during operation.

[0034] The guide column (8) provides a guide for the linear bearing (10) to ensure its linear motion in the vertical direction. The guide column (8) is usually made of wear-resistant material to extend its service life and reduce maintenance requirements.

[0035] The following describes an embodiment of the present invention applied to wheel products. In this embodiment, the present invention provides power for wheel products on an assembly line workbench. Through precise control by a frequency converter, the motor's speed is adjusted, thereby precisely controlling the speed of the wheel products on the assembly line. To transmit the motor's power to the drive system, the motor is connected to a sturdy drive shaft via a precision coupling or gearbox, ensuring smooth and efficient power transmission.

[0036] Multiple synchronous pulleys are mounted equidistantly on this long drive shaft. These pulleys are connected to the drive belt via the timing belt, forming a synchronized unit. This design allows multiple pulleys to operate simultaneously, ensuring smooth and synchronized movement of the wheel products on the assembly line workbench. The meshing between the drive belt and the synchronous pulleys utilizes the traction of the timing belt to drive the wheel products smoothly along the belt.

[0037] To achieve vertical movement of the wheel products, the system is equipped with a lifting device controlled by an intelligent control system. This control system uses signals from a photoelectric sensor to determine the wheel product's position and automatically controls the extension and retraction of the lifting cylinder, thereby precisely controlling the raising and lowering of the synchronous pulley. This automated lifting mechanism ensures smooth transition of the wheel products from the higher assembly line worktable to the synchronous belt.

[0038] During the reversing process, the wheel product first moves from the higher conveyor line on the assembly line's workbench to the edge of the conveyor line. Once the photoelectric sensor detects the object, it immediately sends a signal to the control system, triggering the lifting cylinder. The lifting cylinder then lifts the synchronous belt pulley, aligning the belt surface with the workbench and ensuring a smooth transition for the wheel product. The roller then transfers the product to the synchronous belt, which then transports it to the center of the belt. When the reduction motor stops, the lifting mechanism lowers, lowering the synchronous belt surface below the workbench. The wheel product contacts the rotating roller, completing the product's rotation within the roller line.

[0039] The control logic for the entire reversing mechanism is implemented by a PLC (Programmable Logic Controller), which serves as the brain of the entire system, precisely controlling the movements of the motor, lifting device, and reduction motor. The PLC system also integrates a variety of sensors, such as photoelectric sensors and position sensors, which monitor the reversing process in real time to ensure accurate and reliable operation.

[0040] To ensure operational safety and the long-term stability of the system, emergency stop buttons are located at key locations within the reversing mechanism. This allows for rapid power cutoff and halting of all movement in the event of an emergency. Furthermore, the system implements a regular maintenance schedule, including checking the wear of the timing belts and promptly replacing any worn belts to maintain transmission efficiency. Furthermore, the drive shaft and timing pulleys require regular lubrication to reduce wear, extend their service life, and ensure efficient and stable operation of the entire transmission system.

[0041] The lifting device in this utility model is used for moving up and down, so it includes but is not limited to the following:

[0042] The mechanical jacking mechanism uses the pressure generated by the hydraulic pump to lift the jack, thereby lifting the object; the spiral jacking mechanism uses spiral transmission such as a worm gear or screw to achieve jacking, and the rotation of the screw drives the jack to rise, thereby lifting the object; the hydraulic jacking mechanism uses the pressure generated by the hydraulic oil to achieve jacking, and is mainly composed of a hydraulic cylinder, hydraulic pipelines and support frame, and can adjust the jacking height and speed; the pneumatic jacking mechanism uses gas pressure to achieve jacking.

[0043] The following describes in detail a specific embodiment of the connection between the slider and the pinch wheel in the present invention: In this device, the connection between the slider (12) and the pinch wheel (4) is achieved through an ingeniously designed mechanical structure.

[0044] The slider (12) is usually made of high-strength metal to ensure that it does not deform when subjected to pressure. The contact surface of the slider (12) may be specially treated, such as hardened or coated, to improve wear resistance and corrosion resistance.

[0045] The guide mechanism, which can be a guide rail or a slide, provides a precise movement path for the slider (12) to ensure its linear motion when pressing or releasing the pressing wheel (4). These guide mechanisms may use rolling elements, such as balls or rollers, to reduce friction and improve sliding efficiency.

[0046] The pinch wheel (4) is a key component in the device, and its function is to provide a stable support and precise positioning for the transmission shaft or mechanical parts. The pinch wheel (4) can be designed with preload to ensure stability under high speed or heavy load conditions.

[0047] When compaction is required, the slider (12) moves along the guide rail to the position of the compaction wheel (4) and is pressed tightly against the bearing (4) by spring force, hydraulic (gas) pressure or other mechanical force. This compaction mechanism can be automatic or manual, depending on the application scenario and design requirements.

[0048] The slider (12) may include a thread or a wedge structure, allowing the clamping force to be adjusted by rotation or linear movement. This structure allows the operator to accurately control the clamping force of the clamping wheel (4) to adapt to different working conditions.

[0049] The movement of the slider (12) can be driven by a servo motor or other types of actuators to achieve precise position control. The control system adjusts the position of the slider (12) based on the feedback signal from the sensor to ensure that the pressure of the pressure wheel (4) is maintained at an optimal state. When maintenance or component replacement is required, the slider (12) can be released so that the pressure wheel (4) or related components can be easily removed or installed. This design simplifies maintenance work, reduces downtime, and improves production efficiency.

[0050] The device may include a safety interlock and monitoring system to ensure that the slider (12) and the pressure wheel (4) do not move accidentally during maintenance or in the event of a malfunction. The monitoring system can track the pressure force and position in real time to ensure safe and reliable operation.

[0051] Through this design, the connection between the slider (12) and the pressing wheel (4) can not only achieve accurate pressing and releasing, but also adapt to various working conditions, thereby improving the reliability of the machine and the convenience of maintenance.

[0052] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
