Description

[0002] In modern industrial production, material conveying lines as a key link in the production process have an important influence on production efficiency and product quality. Traditional material conveying lines, such as belt conveying lines, chain conveying lines, etc., mainly rely on mechanical transmission to realize the conveying of materials. Such conveying lines usually adopt a single continuous conveying mode, all materials moving at the same speed on the same conveying path, which has poor flexibility and is difficult to meet diversified and personalized production demands. When the production task changes and the conveying path or speed needs to be adjusted, the entire conveying line often needs to be overhauled, which is time-consuming, labor-intensive and costly.

[0003] In addition, traditional conveying lines have a large friction between mechanical components, which is prone to wear and tear during operation, not only shortening the service life of the equipment, but also increasing maintenance costs and downtime, affecting the continuity and stability of production. At the same time, the automation level of traditional conveying lines is relatively low, and manual intervention is often required in the positioning, control and conversion of materials, which not only increases labor costs, but also is prone to human operation errors, leading to production accidents and material damage.

[0035] The embodiment of the present application discloses an automatic magnetic suspension multi-mover coupling flexible conveying line.

[0036] Please refer to Figures 1-8 In an embodiment of the present application, an automatic magnetic suspension multi-mover coupling flexible conveying line comprises two groups of parallelly arranged stator guide rail devices 100, a plurality of mover suspension devices 200 are slidably connected on the stator guide rail devices 100, a suspension gas device 300 and a braking gas device 400 are connected on the stator guide rail devices 100 corresponding to the mover suspension devices 200, a magnetic force driving device 500 and a detection device 600 are installed between the stator guide rail devices 100 and the mover suspension devices 200, anti-collision devices 700 are arranged at both ends of the mover suspension devices 200, and transfer devices 800 are arranged at both ends of the two groups of stator guide rail devices 100 corresponding to the mover suspension devices 200; the suspension gas device 300, the braking gas device 400, the magnetic force driving device 500, the detection device 600, the anti-collision device 700 and the transfer device 800 are electrically connected with a control device 900.

[0037] In the working process, the control device 900 sends instructions to the suspension gas device 300 to generate positive pressure gas, forming an air film between the stator guide rail device 100 and the mover suspension device 200, lifting the mover suspension device 200 and greatly reducing the friction between the two. At the same time, the magnetic force driving device 500 generates magnetic force under the control of the control device 900, driving the corresponding mover suspension device 200 to slide smoothly along the stator guide rail device 100. The detection device 600 monitors the position and speed of the mover suspension device 200 in real time and feeds back the data to the control device 900. The control device 900 adjusts the size and direction of the magnetic force of the magnetic force driving device 500 in a timely manner according to these data, ensuring that each mover suspension device 200 operates according to the predetermined path and speed. When the mover suspension device 200 needs to stop, the control device 900 controls the brake gas device 400 to generate negative pressure gas to adsorb the mover suspension device 200 on the stator guide rail device 100, so that it stops quickly. The anti-collision device 700 at both ends of the mover suspension device 200 plays a safety protection role in the running process, avoiding collision between the movers. The two sets of stator guide rail devices 100 at both ends of the transfer device 800 can realize smooth transition and conversion of the mover suspension device 200 between different stator guide rail devices 100 under the control of the control device 900, meeting the diversified conveying needs.

[0038] Please refer to Figures 1-8 In a specific embodiment of the present application, the stator guide rail device 100 includes a mounting bracket 102 fixedly installed on the mounting seat 101, and a guide rail 103 fixedly installed on the mounting bracket 102. The mover suspension device 200 is installed on the guide rail 103. The guide rail 103 is provided with uniformly distributed air guide holes 104 along the length direction thereof towards the mover suspension device 200. The guide rail 103 is internally provided with an air guide channel 105 communicating with all the air guide holes 104. The guide rail 103 is fixedly and sealingly provided with a connecting pipe 106 in communication with the air guide channel 105. The connecting pipe 106 is connected with a three-way pipe 107 at the end away from the mounting bracket 102. The other two ends of the three-way pipe 107 are connected with the suspension gas device 300 and the brake gas device 400, respectively.

[0039] In the working process, when the control device 900 issues an instruction to the suspension gas device 300, the gas enters the gas guide channel 105 inside the guide rail 103 through the tee pipe 107 and the connecting pipe 106, is discharged through the uniformly distributed gas guide holes 104, and forms an air film between the guide rail 103 and the mover suspension device 200, which lifts the mover suspension device 200, reduces the friction between the two, and enables the mover suspension device 200 to slide along the guide rail 103 under the action of the magnetic force driving device 500. When the mover suspension device 200 needs to stop, the control device 900 controls the braking gas device 400 to work, the braking gas device 400 connects the guide rail 103 through the same path, but negative pressure gas is generated at this time, the mover suspension device 200 is adsorbed on the guide rail 103 through the gas guide holes 104, and braking is realized. The detection device 600 monitors the running state of the mover suspension device 200 in real time and feeds back to the control device 900, which controls the output of the gas and the working of the magnetic force driving device 500, thereby guaranteeing the stable operation of the conveying line.

[0040] Please refer to Figures 1-8 In a specific embodiment of the present application, the mover suspension device 200 includes a sliding block 201 which is slidingly connected to the guide rail 103. The sliding block 201 is provided with a sliding groove 202 on the side close to the guide rail 103, which corresponds to the cross-sectional shape of the guide rail 103. A gap for forming an air film is arranged between the inner surface of the sliding groove 202 and the outer surface of the guide rail 103. A connecting seat 203 is mounted on the side of the sliding block 201 away from the guide rail 103. The magnetic force driving device 500 and the detection device 600 are respectively mounted on the two side surfaces of the connecting seat 203. The anti-collision devices 700 are symmetrically mounted on the two end surfaces of the connecting seat 203.

[0041] In the working process, the suspension gas device 300 in the stator guide rail device 100 generates gas, forms an air film through the gas guide channel 105 and the gas guide hole 104, lifts the sliding block 201 of the mover suspension device 200, and enables the sliding block 201 to be suspended on the guide rail 103. At this time, the sliding groove 202 on the sliding block 201 cooperates with the guide rail 103 to play a guiding role, ensuring that the sliding block 201 stably slides along the guide rail 103. The magnetic force driving device 500 is installed on the side surface of the connecting seat 203 and generates a magnetic force under the regulation of the control device 900, driving the mover suspension device 200 to move along the guide rail 103. The detection device 600 is also installed on the side surface of the connecting seat 203 and monitors the position, speed and other operating parameters of the mover suspension device 200 in real time, and feeds back the data to the control device 900, so that the control device 900 adjusts the size and direction of the magnetic force of the magnetic force driving device 500 in time, maintaining the stable operation of the mover suspension device 200. When the mover suspension device 200 needs to stop, the braking gas device 400 generates negative pressure gas to adsorb the sliding block 201 on the guide rail 103. The anti-collision devices 700 on the two end surfaces of the connecting seat 203 protect in real time during the operation process, avoid the collision between the mover suspension device 200 and other objects, and guarantee the safety of the conveying.

[0042] Please refer to Figures 1-8 In an embodiment of the present application, the suspension gas device 300 comprises a vacuum pump 301, the output end of the vacuum pump 301 is fixedly and sealingly connected with an output pipe 302, the end of the output pipe 302 away from the vacuum pump 301 is fixedly and sealingly connected with a pressure stabilizing tank 303, the pressure stabilizing tank 303 is fixedly and sealingly connected with a first electric control valve 304, the first electric control valve 304 is sealingly connected with a positive pressure pipe 305, and the positive pressure pipe 305 is sealingly connected with the three-way pipe 107.

[0043] In the working process, when the automatic magnetic suspension multi-mover coupling flexible conveying line starts to run, the control device 900 sends a start instruction to the vacuum pump 301 in the suspension gas device 300. The vacuum pump 301 starts to work, extracts air and transmits the gas into the pressure stabilizing tank 303 through the output pipe 302. The pressure stabilizing tank 303 performs pressure stabilizing treatment on the gas, so that the gas pressure remains stable, avoiding the influence of pressure fluctuation on the suspension effect. Subsequently, the control device 900 controls the first electric control valve 304 to open, and the positively pressurized gas enters the three-way pipe 107 through the positive pressure pipe 305, and then flows into the connecting pipe 106 and the gas guiding channel 105 of the stator guide rail device 100 in sequence, and finally is discharged from the gas guiding hole 104, forming a uniform and stable gas film between the guide rail 103 and the mover suspension device 200, lifting the mover suspension device 200, so that it can slide stably and with low friction along the guide rail 103 under the action of the magnetic force driving device 500.

[0044] Please refer to Figures 1-8 In an embodiment of the present application, the brake gas device 400 comprises an input pipe 401, the input pipe 401 is fixedly and sealingly connected with the input end of the vacuum pump 301, the end of the input pipe 401 away from the vacuum pump 301 is fixedly and sealingly connected with a vacuum tank 402, the vacuum tank 402 is fixedly and sealingly connected with a second electric control valve 403, the pressure stabilizing tank 303 is fixedly and sealingly connected with a pressure relief valve 404, the vacuum tank 402 is fixedly and sealingly connected with a vacuum breaking valve 405, the second electric control valve 403 is sealingly connected with a negative pressure pipe 406, and the negative pressure pipe 406 is sealingly connected with the three-way pipe 107.

[0045] In the working process, when the mover suspension device 200 needs to be braked, the control device 900 sends an instruction to the braking gas device 400 to control the second electric control valve 403 to open. At this time, the vacuum pump 301 extracts gas from the vacuum tank 402 through the input pipe 401, so that a negative pressure environment is formed in the vacuum tank 402, and the negative pressure gas enters the three-way pipe 107 through the negative pressure pipe 406, and then flows into the connecting pipe 106 and the gas guide channel 105 of the stator guide rail device 100, and is discharged from the gas guide hole 104. The adsorption force generated by the negative pressure gas firmly adsorbs the mover suspension device 200 on the guide rail 103, so that the mover suspension device 200 stops moving quickly. After braking, the control device 900 controls the vacuum breaking valve 405 to open, so that the outside air enters the vacuum tank 402 to destroy the negative pressure state thereof, facilitating subsequent operation; at the same time, the control device 900 controls the pressure relief valve 404 to open, so as to release the excess gas in the pressure stabilizing tank 303, and prepare for the next suspension gas output. In the whole process, the vacuum pump 301 is shared with the suspension gas device 300, and the gas functions of suspension and braking are switched through different pipelines and valve controls.

[0046] Please refer to Figures 1-8 In one specific embodiment of the present application, the magnetic driving device 500 includes a magnetic body 501, a first mounting plate 502 is fixedly installed on one side of the connecting seat 203, and the magnetic body 501 is fixed on the first mounting plate 502; a plurality of first electromagnetic components 503 are fixedly installed on the side surface of the mounting bracket 102 at equal intervals, the first electromagnetic components 503 are arranged along the length direction of the guide rail 103, and the first electromagnetic components 503 are arranged correspondingly with the magnetic body 501.

[0047] In the working process, when the magnetic driving device 500 operates, the control device 900 transmits a current signal to the first electromagnetic component 503. After the first electromagnetic component 503 is electrified, a magnetic field is generated, and an electromagnetic interaction force is generated with the magnetic body 501 fixed on the first mounting plate 502 of the connecting seat 203. When the control device 900 changes the current size and direction of the first electromagnetic component 503, the strength and direction of the magnetic field generated thereby also change, and then the electromagnetic force size and direction between the first electromagnetic component 503 and the magnetic body 501 are adjusted. Under the action of the electromagnetic force, the magnetic body 501 of the mover suspension device 200 drives the entire mover suspension device 200 to move along the guide rail 103. At the same time, the detection device 600 monitors the position, speed and other parameters of the mover suspension device 200 in real time, and feeds back to the control device 900, and the control device 900 adjusts the current of the first electromagnetic component 503 in time according to the feedback data, so as to realize precise control of the running state of the mover suspension device 200, and make it run stably according to the predetermined path and speed.

[0048] Please refer to Figures 1-8In an embodiment of the present application, the detection device 600 comprises a grating ruler 601, a second mounting plate 602 is fixedly installed on one side of the connecting seat 203, and the grating ruler 601 is fixedly installed on the second mounting plate 602; a plurality of first grating detectors 603 are fixedly installed on the side surface of the mounting bracket 102 at equal intervals, the first grating detectors 603 are electrically connected with the control device 900, the first grating detectors 603 are arranged along the length direction of the guide rail 103, and the first grating detectors 603 are arranged correspondingly with the grating ruler 601.

[0049] In the working process, when the detection device 600 operates, the grating ruler 601 fixed on the second mounting plate 602 of the connecting seat 203 moves along the guide rail 103 together with the rotor suspension device 200. The first grating detectors 603 distributed at equal intervals on the mounting bracket 102 along the length direction of the guide rail 103 continuously emit and receive light signals. When the grating ruler 601 passes through the first grating detectors 603, the light signals will change in shielding or transmission, the first grating detectors 603 convert the change of the light signals into electric signals and transmit the electric signals to the control device 900. The control device 900 calculates the real-time position, moving speed and other operating parameters of the rotor suspension device 200 by analyzing the change frequency and quantity of the received electric signals. According to these parameters, the control device 900 can timely adjust the working state of the magnetic force driving device 500, such as changing the current size and direction of the first electromagnetic member 503, so as to realize accurate regulation and control of the running state of the rotor suspension device 200 and ensure that the rotor suspension device 200 stably operates according to the predetermined path and speed.

[0050] Please refer to Figures 1-8 In an embodiment of the present application, the anti-collision device 700 comprises anti-collision blocks 701 fixedly installed at both ends of the connecting seat 203, an exhaust groove 702 is formed in the sliding block 201 and penetrates the sliding groove 202, a first exhaust passage 703 is formed in the guide rail 103 and communicates with the exhaust groove 702, a second exhaust passage 704 is formed in the connecting seat 203 and sealingly communicates with the first exhaust passage 703, and exhaust holes 705 are formed in the anti-collision blocks 701 and communicate with the second exhaust passage 704 along the length direction of the guide rail 103.

[0051] In the working process, when the rotor suspension device 200 operates on the guide rail 103, the positive pressure gas generated by the suspension gas device 300 enters the first exhaust passage 703 through the gas guide passage 105 of the guide rail 103, then passes through the exhaust groove 702 of the sliding block 201 and the second exhaust passage 704 of the connecting seat 203, and finally is exhausted from the exhaust holes 705 of the anti-collision blocks 701. If the distance between two adjacent rotor suspension devices 200 is too small, the exhausted gas will be offset between the two anti-collision blocks 701, thereby buffering the collision energy and reducing the impact force of direct contact.

[0052] Please refer to Figures 1-8 In one specific embodiment of the present application, the number of exhaust holes 705 is two, the two exhaust holes 705 on the two adjacent anti-collision blocks 701 are coaxially aligned, the exhaust hole 705 on the same anti-collision block 701 is fixedly and sealingly installed with a sealing plug 706, the sealing plug 706 is elastically connected with a movable plug 707, a pressure sensor 708 is arranged between the sealing plug 706 and the movable plug 707, and the exhaust hole 705 with the sealing plug 706 installed in the adjacent two anti-collision blocks 701 is coaxially aligned with the other exhaust hole 705 without the sealing plug 706 installed.

[0053] In the working process, when the two adjacent mover suspension devices 200 approach each other, the coaxially aligned exhaust holes 705 form an air flow channel. The exhaust hole 705 without the sealing plug 706 installed discharges the positive pressure gas towards the inside of the exhaust hole 705 with the sealing plug 706 installed, and the movable plug 707 compresses the spring and moves towards the sealing plug 706 under the action of the gas pressure. At this time, the pressure sensor 708 monitors the pressure change between the movable plug 707 and the sealing plug 706 in real time, and transmits the signal to the control device 900. When the pressure value exceeds the preset threshold value, the control device 900 determines that there is a risk of collision, immediately controls the braking gas device 400 to start, and at the same time adjusts the magnetic force driving device 500 to reduce the speed of the mover or changes the running direction, realizing multiple protection.

[0054] Please refer to Figures 1-8 In one specific embodiment of the present application, the transfer device 800 includes a transfer slide rail 801, a transfer slide block 802 is slidingly connected on the transfer slide rail 801, a driving member is installed between the transfer slide rail 801 and the transfer slide block 802, a transfer bracket 803 is installed on the transfer slide block 802, a transfer guide rail 804 is installed on the transfer bracket 803 corresponding to the mover suspension device 200, the transfer guide rail 804 is flush with the stator guide rail device 100, a second electromagnetic member 805 is installed on the transfer bracket 803 corresponding to the magnetic force driving device 500, and a second grating detector 806 is installed on the transfer bracket 803 corresponding to the detection device 600.

[0055] In the working process, the driving member provides power for the sliding of the transfer sliding block 802 on the transfer sliding rail 801, enabling it to move along the sliding rail. When it is necessary to transfer the mover levitation device 200 from the corresponding stator guide rail device 100 to the transfer device 800, the transfer sliding block 802 moves to a position flush with the corresponding stator guide rail device 100 under the action of the driving member, aligning the transfer guide rail 804 with the guide rail 103. At the same time, the second electromagnetic member 805 and the second grating detector 806 are respectively arranged corresponding to the magnetic force driving device 500 and the detection device 600 to realize the functions of magnetic force driving and position detection of the mover levitation device 200. During the transfer process, the magnetic force driving device 500 interacts with the second electromagnetic member 805 to provide driving force for the mover levitation device 200, enabling it to move on the transfer guide rail 804. The detection device 600 and the second grating detector 806 monitor the position information of the mover levitation device 200 in real time, ensuring that it moves accurately on the guide rail, and feed back the position signal to the control device 900 for accurate control and adjustment.

[0056] It can be understood that in the specific embodiments of the present application, the driving member can be a power device such as a motor, a pneumatic cylinder, etc., which transmits power to the transfer sliding block 802 through a transmission mechanism such as a lead screw, a chain, etc. The driving member can also directly use a linear motor to directly transmit power to the transfer sliding block 802, thereby realizing accurate position control.

[0057] Please refer to Figures 1-8 In a specific embodiment of the present application, a limiting seat 807 is installed on the transfer support 803 away from the stator guide rail device 100, and a buffer pad is installed on the limiting seat 807 corresponding to the mover levitation device 200.

[0058] In the working process, when the mover levitation device 200 moves on the transfer guide rail 804, the limiting seat 807 functions to limit its movement range. When the mover levitation device 200 approaches the limiting seat 807, the buffer pad first contacts the mover levitation device 200. The buffer pad is usually made of a material with elasticity, such as rubber, polyurethane, etc., which can deform when the two contact, absorbing and buffering the kinetic energy of the mover levitation device 200, thereby slowing down its speed, and finally stopping the movement of the mover levitation device 200 at the limiting seat 807, preventing it from exceeding the predetermined position range due to inertia, causing damage to the equipment or triggering a safety accident.

[0059] Please refer to Figures 1-8 In a specific embodiment of the present application, a position detector 808 is installed on the transfer sliding rail 801 corresponding to each of the two groups of stator guide rail devices 100, and a position detection plate 809 is fixedly installed on the transfer sliding block 802 corresponding to the position detector 808.

[0060] In the working process, when the ferry slider 802 moves on the ferry rail 801, the position detection plate 809 moves synchronously with the slider. When the position detection plate 809 passes the position detector 808, the position detector 808 detects the position information of the position detection plate 809 and converts the information into an electrical signal and sends it to the control device 900. According to the received signal, the control device 900 can accurately determine whether the ferry slider 802 reaches the predetermined position aligned with the stator rail device 100. When it is detected that the position detection plate 809 is aligned with the position detector 808 of the corresponding stator rail device 100, the control device 900 controls the driving member to stop running, so that the ferry slider 802 is accurately stopped at the target position, ensuring that the ferry rail 804 is flush with the rail 103 of the stator rail device 100, and providing protection for the smooth transfer of the mover suspension device 200.

[0061] Please refer to ​ In an embodiment of the present application, the control device 900 includes a controller 901, which is electrically connected with the suspension gas device 300, the braking gas device 400, the magnetic driving device 500, the detection device 600, the anti-collision device 700, and the ferry device 800. The controller 901 is electrically connected with a control panel 902 and a display 903.

[0062] In the working process, the controller 901, as the core of the whole system, receives signals from various devices and processes and analyzes these signals according to the preset program and logic. According to the received signals, the controller 901 sends control instructions to various devices. The control panel 902 is used for the operator to input various control parameters and instructions, such as setting the running speed, running path, and stopping position of the mover suspension device 200. These information will be transmitted to the controller 901, so that the controller 901 controls the system according to the requirements of the operator. The display 903 is used to display various running state information of the system, such as the current position and speed of the mover suspension device 200, the working state of each device, and possible fault information, etc., so that the operator can real-time understand the system running situation and timely find and handle problems.

[0063] The implementation principle of the embodiment of the application is as follows:

[0064] Operators input control parameters and commands through the control panel 902, while the display 903 shows the system's operating status in real time. The control device 900 coordinates and controls the operation of the entire conveyor line according to preset programs and received signals. Under control commands, the suspending gas device 300 generates positive pressure gas, which forms an air film through the stator guide rail device 100, supporting the mover suspending device 200. Simultaneously, the magnetic drive device 500 generates electromagnetic force to drive the mover along the guide rail. The detection device 600 monitors the mover's position and speed in real time and provides feedback data. The control device 900 dynamically adjusts the magnitude and direction of the magnetic force accordingly to ensure the mover runs along the predetermined path. During braking, the braking gas device 400 generates negative pressure gas to adsorb the mover for precise stopping. The anti-collision device 700 uses a dual mechanism of air buffering and pressure sensing warning to prevent collisions. When switching conveyor paths is required, the drive component of the transfer device 800 moves the transfer slider to the designated position. Through the cooperation of the second electromagnetic component 805 and the second grating detector 806 with the mover, the mover is smoothly transferred between different guide rails. All devices operate collaboratively under the unified control of the control device 900, thereby achieving diversified and flexible material transportation, improving transportation efficiency and the level of intelligent production, and meeting the needs of modern industrial production.

[0065] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
