[0002] A suspended conveyor system is an automated equipment system that uses overhead tracks to achieve continuous material transport in three-dimensional space. It mainly consists of tracks, traction chains, lifting devices, and drive units. Suspended conveyor systems include chain-type suspended conveyors, servo motor-driven suspended conveyors, and electromagnetic drive suspended conveyor systems. Among them, the servo motor-driven suspended conveyor is an advanced material transport equipment that uses a servo motor as a power source.

Multiple support balls are rolled and embedded in a linear array on the lower surface of the bottom end of the slider support rail. The speed gearbox rolls and contacts the slider support rail through the support balls.

[0009] Preferably, the input end of the gearbox is connected to a drive shaft, the top end of the drive shaft extends through the top of the drive shaft, a conversion bevel gear is fixed to the top end of the drive shaft, an output bevel gear is meshed above the conversion bevel gear, a dual-axis servo motor is provided between the two output bevel gears, the two output bevel gears are respectively fixed to the ends of the two drive shafts of the dual-axis servo motor, and the dual-axis servo motor is fixed to the upper surface of the guide rail slider and located in the middle of the two identification information plates.

[0010] Preferably, the inner top surface of the guide rail body is provided with multiple sets of two symmetrically positioned storage slots, the distance between the two storage slots is two to five times the length of the guide rail slider, and a speed adjustment module is installed on the inner side of the storage slot.

[0011] Preferably, the speed control module includes a battery, which is located inside the conveyor rail module and has a heat dissipation window on one side. The heat dissipation window is used for heat dissipation when the speed control module is working. The electrodes of the battery are connected to connecting wires. One end of the connecting wire extends into the storage slot and is fixed with an adjusting electromagnet. A lifting plate is fixed to the outside of the adjusting electromagnet. The end of the connecting wire located inside the storage slot is covered with a plastic elastic shrink sleeve, which is spirally wound to form a spring structure.

[0012] Preferably, two symmetrical adjustable electric telescopic rods are fixed on the upper surface of the lifting plate. The top of the adjustable electric telescopic rods is fixed to the guide rail body. An infrared ranging sensor is embedded in the end of the lifting plate facing the guide rail slider. Magnets are fixed inside both ends of the guide rail slider.

[0013] Preferably, the conveying suspension module includes a sling and a hook, the sling being fixed to the bottom of the guide rail slider, and the hook being detachably installed at the bottom end of the sling.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. When the present invention transports goods through a suspended conveyor system, the adjusting electromagnet located behind the guide rail slider in the forward direction is energized to repel the magnet at the end of the guide rail slider. The repulsive force causes the guide rail slider to slide inside the conveyor rail module. At the same time as the adjusting electromagnet is energized, the dual-axis servo motor is energized and the drive shaft of the dual-axis servo motor drives the output bevel gear to rotate. The output bevel gear drives the transmission shaft to rotate through the conversion bevel gear. The transmission shaft transmits power to four pulleys through the gearbox, causing the pulleys to run. When the guide rail slider starts, the magnetic repulsion of the guide rail slider by the adjusting electromagnet reduces the output torque of the dual-axis servo motor and the rotational load of the drive shaft, avoiding damage or failure of the dual-axis servo motor due to high torque and high load during startup, and extending the service life of the dual-axis servo motor.

[0017] 2. This invention, during the deceleration process of the guide rail slider, adjusts the energization of an electromagnet to repel the magnet inside the guide rail slider. During this process, the current supplied to the electromagnet gradually decreases as the guide rail slider gets closer to the electromagnet, until the current supply to the electromagnet is zero. This avoids the guide rail slider stopping before reaching its destination due to the constant repulsive force of the electromagnet on the guide rail slider. At the same time, the brake assembly brakes the pulley and stops the guide rail slider, effectively reducing the operating load of the brake assembly and the wear caused by braking, and extending the service life of the brake module of the servo drive intelligent suspension system.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a servo-driven intelligent suspended conveying system includes a conveying guide rail module 1, a guide rail slider 2, a slider drive module 3, a conveying suspension module 4, and a control module 5. The slider drive module 3 is located on the outside of the guide rail slider 2, while the guide rail slider 2 is located on the inside of the conveying guide rail module 1. The conveying suspension module 4 is located at the bottom of the guide rail slider 2. The slider drive module 3 provides power output for the movement of the guide rail slider 2. Two symmetrical identification information plates 7 are fixed on the upper surface of the guide rail slider 2. Multiple scanning sensor plates 6 are linearly arrayed along the length direction inside the conveying guide rail module 1. The control module 5 is electrically connected to the scanning sensor plates 6 and the slider drive module 3. The scanning sensor plates 6 identify the information on the identification information plates 7 and feed the signal back to the control module 5, thereby realizing real-time control of the position and moving speed of the guide rail slider 2.

[0027] The conveying suspension module 4 includes a sling and a hook. The sling is fixed to the bottom of the guide rail slider 2, while the hook is detachably installed at the bottom of the sling.

[0028] Control module 5 includes an encoder, a power supply, a signal transceiver, and a signal conversion chip.

[0029] like Figure 1 and 3 As shown, the conveying guide rail module 1 includes a guide rail body 101. Two parallel slider support rails 102 are detachably mounted on the bottom of the guide rail body 101. Fastening screws 103 are inserted through the top side of the slider support rails 102. The ends of the fastening screws 103 are inserted into the side of the guide rail body 101 and connected to the guide rail body 101 by threads.

[0030] A guide groove 105 is provided between the bottom end of the slider support rail 102 and the guide rail body 101. A pulley 306 is rolled inside the guide groove 105, and a contact ball 307 is rolled and embedded at the center of the end of the pulley 306 facing the inner wall of the guide rail body 101. The contact ball 307 rolls and contacts the inner wall of the guide rail body 101. Multiple support balls 104 are rolled and embedded in a linear array on the upper surface of the bottom end of the slider support rail 102. The gearbox 305 rolls and contacts the slider support rail 102 through the support balls 104. The guide groove 105 guides the movement of the pulley 306, while the contact ball 307 reduces the coefficient of friction and resistance between the pulley 306 and the guide rail body 101. At the same time, the support ball 104 reduces the frictional resistance between the gearbox 305 and the slider support rail 102, making the guide rail slider 2 move more smoothly.

[0031] like Figure 2 and Figure 4 As shown, the slider drive module 3 includes two symmetrically distributed gearboxes 305. The two gearboxes 305 are fixed on both sides of the guide rail slider 2 and located above the slider support rail 102. Each gearbox 305 has one input shaft and two output shafts. One end of each of the two output shafts of the gearbox 305 is located outside the gearbox 305 and a pulley 306 is fixed at this end. A brake assembly is provided between the output shafts of the gearbox 305 and the pulleys 306.

[0032] The two drive shafts of the dual-axis servo motor 301 are connected to torque sensors and speed sensors, and the two output shafts of the gearbox 305 are connected to speed sensors. The brake assembly, torque sensors, and speed sensors are electrically connected to the control module 5. The output torque and speed of the dual-axis servo motor 301 and the gearbox 305 are monitored by the torque sensors and speed sensors, so as to calculate the moving speed of the guide rail slider 2 and whether the guide rail slider 2 is in a deceleration or acceleration state.

[0033] The input end of the gearbox 305 is connected to the drive shaft 304. The top end of the drive shaft 304 passes through the top of the drive shaft 304. A conversion bevel gear 303 is fixed to the top end of the drive shaft 304. An output bevel gear 302 is meshed above the conversion bevel gear 303. A dual-axis servo motor 301 is located between the two output bevel gears 302. The two output bevel gears 302 are respectively fixed to the ends of the two drive shafts of the dual-axis servo motor 301. The dual-axis servo motor 301 is fixed to the upper surface of the guide rail slider 2 and is located in the middle of the two identification information plates 7. The dual-axis servo motor 301, the output bevel gear 302, the conversion bevel gear 303, the drive shaft 304 and the gearbox 305 drive the four pulleys 306 to rotate in the same direction. This causes the pulleys 306 to move along the guide rail groove 105 and drive the guide rail slider 2 and the bottom conveyor suspension module 4 of the guide rail slider 2 to transport goods along the conveyor guide rail module 1.

[0034] like Figure 5 and Figure 6 As shown, the inner top surface of the guide rail body 101 is provided with multiple sets of two symmetrically positioned storage slots 8. The distance between the two storage slots 8 is two to five times the length of the guide rail slider 2. A speed control module 9 is installed inside the storage slot 8. The speed control module 9 includes a battery 901. The battery 901 is located inside the conveying guide rail module 1, and a heat dissipation window is provided on one side of the conveying guide rail module 1. The heat dissipation window is used for heat dissipation when the speed control module 9 is working. The electrodes of the battery 901 are connected to connecting wires 903. One end of the connecting wire 903 extends into the storage slot 8 and is fixed with an adjusting electromagnetic... Iron 906, an adjusting electromagnet 906 has a lifting plate 905 fixed on its outer side, and a plastic elastic shrink sleeve 904 is sleeved on the outer side of the end of the connecting wire 903 located inside the storage groove 8. The plastic elastic shrink sleeve 904 is spirally wound to form a spring structure. The tension of the connecting wire 903 is adjusted by the plastic elastic shrink sleeve 904. After the adjusting electric telescopic rod 902 is activated, the stability of the connecting wire 903 is ensured, and the connecting wire 903 is prevented from being clamped between the lifting plate 905 and the guide rail body 101 due to loosening, thereby preventing damage to the connecting wire 903.

[0035] Two symmetrical adjustable electric telescopic rods 902 are fixed on the upper surface of the lifting plate 905. The top of the adjustable electric telescopic rods 902 is fixed to the guide rail body 101. An infrared ranging sensor 907 is embedded in the end of the lifting plate 905 facing the guide rail slider 2. Magnets are fixed inside both ends of the guide rail slider 2. The magnetic poles of the magnets facing the adjusting electromagnet 906 are the same as the magnetic poles generated when the adjusting electromagnet 906 is energized. The lifting plate 905 and the adjusting electromagnet 906 are controlled by adjusting the electric telescopic rods 902. The adjusting electromagnet 906 is powered by the battery 901 and the connecting wire 903. The guide rail slider 2 is decelerated or accelerated by the repulsion of the magnet inside the end of the adjusting electromagnet 906.

[0036] Working principle: When transporting goods using the servo-driven intelligent suspension conveying system, the goods are first suspended by the conveying suspension module 4. After the goods are suspended, the power supply of the entire system is turned on and started. After the system starts, the adjusting electric telescopic rod 902 located behind the guide rail slider 2 in the forward direction starts and drives the lifting plate 905 and adjusting electromagnet 906 connected to it to descend, so that the center line of the adjusting electromagnet 906 coincides with the center line of the guide rail slider 2. At this time, the battery 901 supplies power to the adjusting electromagnet 906 through the connecting wire 903. After the adjusting electromagnet 906 is energized, it repels the magnet at the end of the guide rail slider 2. The repulsive force causes the guide rail slider 2 to slide inside the conveying guide rail module 1. At this time, the pulley 306 rolls inside the guide rail guide groove 105.

[0037] While the electromagnet 906 is energized, the dual-axis servo motor 301 is energized, and the drive shaft of the dual-axis servo motor 301 drives the output bevel gear 302 to rotate. The output bevel gear 302 drives the transmission shaft 304 to rotate through the conversion bevel gear 303. The transmission shaft 304 transmits power to the four pulleys 306 through the gearbox 305. At this time, the pulleys 306 move inside the guide groove 105 of the slide rail due to the power transmission of the transmission shaft 304. Since the guide rail slider 2 starts to move due to the repulsive force of the electromagnet 906, the output torque of the dual-axis servo motor 301 and the rotational load of the drive shaft are reduced compared with the traditional method. This reduces the burden on the dual-axis servo motor 301 when starting, avoids damage or failure of the dual-axis servo motor 301 due to high torque and high load during startup, and extends the service life of the dual-axis servo motor 301.

[0038] After the guide rail slider 2 moves away from the adjusting electromagnet 906, the adjusting electric telescopic rod 902 retracts and drives the lifting plate 905 and the adjusting electromagnet 906 to reset. At the same time, the battery 901 stops energizing the adjusting electromagnet 906. At this time, the guide rail slider 2 drives the goods to be transported along the bottom of the conveying guide rail module 1 through the conveying suspension module 4. During this process, the identification information plate 7 on the top of the guide rail slider 2 passes under the scanning sensor plate 6. After the identification information plate 7 passes, the scanning sensor plate 6 feeds back the identification signal to the control module 5. At the same time, the torque sensor and the speed sensor feed back the running torque and speed of the dual-axis servo motor 301 and the speed of the pulley 306 to the control module 5. After receiving the signal, the control module 5 performs identification and data conversion to obtain the real-time position and real-time speed of the guide rail slider 2 inside the conveying guide rail module 1.

[0039] When the goods are transported to the designated location, the dual-axis servo motor 301 cuts off the power and stops power output. At this time, the power from the transmission shaft 304 to the pulley 306 disappears. The guide rail slider 2 continues to slide inside the conveying guide rail module 1 by relying on its speed inertia. At this time, the adjusting electric telescopic rod 902 inside the storage slot 8 located in front of the guide rail slider 2 in the direction of movement is activated. The adjusting electric telescopic rod 902 drives the lifting plate 905 and the adjusting electromagnet 906 to descend. At the same time, the battery 901 supplies power to the adjusting electromagnet 906. After the adjusting electromagnet 906 is energized, it repels the magnet inside the end of the guide rail slider 2 in the inertial sliding of the guide rail slider 2, thereby reducing the speed of the guide rail slider 2.

[0040] The distance between the guide rail slider 2 and the adjusting electromagnet 906 is monitored in real time by the infrared ranging sensor 907. The current supply of the adjusting electromagnet 906 gradually decreases as the guide rail slider 2 gets closer and closer to the adjusting electromagnet 906 until the current supply of the adjusting electromagnet 906 is zero. This avoids the guide rail slider 2 from stopping before it reaches the designated position due to the constant repulsive force of the adjusting electromagnet 906 on the guide rail slider 2. During the process of the adjusting electromagnet 906 gradually decreasing the current, the pulley 306 is braked by the braking assembly to ensure that the guide rail slider 2 stops at the designated position.

[0041] During deceleration, the moving speed of the guide rail slider 2 is reduced by adjusting the repulsion of the electromagnet 906 against the guide rail slider 2. Then, the brake assembly brakes the pulley 306 and stops the guide rail slider 2, effectively reducing the operating load of the brake assembly and the wear caused by braking, and extending the service life of the brake module of the servo drive intelligent suspension system.

[0042] 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 invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention.
