Description

Technical Field

[0001] The present invention relates to the field of storage equipment, in particular to a transport trolley and a matching track for sorting and inspection, and specifically to a magnetic transport system and a method for using the same. Background Art

[0002] In a warehousing system, when ground space is limited, a conveying system is often arranged in the air. The conveying system includes an aerial track that shuttles between various transportation sites and a transport trolley that runs on the aerial track.

[0003] For the above-mentioned conveying system, when more and more transport stations are set, the aerial track will become complicated. For example, a switching mechanism needs to be set between different transport stations to realize the operations of changing tracks and turning for loading and unloading.

[0004] For the reversing mechanism, generally including the disc rotary track change system, parallel movement track change system, up and down movement track change system proposed in announcement numbers CN218023754U, CN217758134U, etc., they all need to be equipped with a power mechanism to provide driving force and cooperate with the track change and turning operations of the transport vehicle.

[0005] As these reversing mechanisms increase in number, the transportation network formed by the aerial track will undoubtedly become more and more complicated and bloated; and for the transport vehicle, in order to adapt to the reversing mechanism of the aerial track, a reversing wheel system such as that proposed in announcement number CN110329282A has to be set on the vehicle body.

[0006] The above-mentioned reversing mechanism, reversing wheel system and supporting power mechanism will undoubtedly reduce the reliability of the entire conveying system and increase the maintenance cost. It can be seen that there is still room for improvement for the current aerial conveying system in the warehousing field. Summary of the invention

[0007] The purpose of the present invention is to overcome the above-mentioned defects and to propose a simpler aerial track and a matching magnetic carrier, which operate based on intelligent automatic control technology, thereby improving the operating efficiency and reliability of the entire transportation system, while also reducing the use cost of the transportation system.

[0008] In order to achieve the above object, the present invention is achieved in the following ways:

[0009] A magnetic transportation system comprises an aerial track without a reversing mechanism and a magnetic attraction transport vehicle; the aerial track without a reversing mechanism comprises a straight track segment and a cross track segment, the straight track segment and the cross track segment are spliced ​​to form a grid-like track network, the track network is used for the magnetic attraction transport vehicle to travel on it by utilizing magnetic adsorption and relying on electric drive; the magnetic attraction transport vehicle comprises a frame, a vehicle control chip, a drive motor and a battery arranged on both sides of the middle of the frame, and also comprises drive wheels connected to the drive motor and located on the left and right sides of the frame, a strong magnetic suction cup is provided on the frame, the strong magnetic suction cup is used to adsorb the entire magnetic attraction transport vehicle on the aerial track, the drive wheel is used to drive the entire magnetic attraction transport vehicle to travel on the aerial track, the battery is used as a power source to supply power to the entire magnetic attraction transport vehicle, the drive motor, the battery and the vehicle control chip are connected via a data line and a power line and are controlled by the vehicle chip.

[0010] Furthermore, in the above-mentioned aerial track without a reversing mechanism, the cross track segment includes a platform and a track extension segment arranged around the platform, and the track extension segment is used for splicing with the straight track segment.

[0011] Furthermore, the above-mentioned aerial track without a reversing mechanism, the straight track section and the cross track section are all made of plate-shaped magnetic metal profiles.

[0012] The present invention first proposes an aerial track system as described above. Compared with the traditional track system, the aerial track system omits the steering mechanism for switching and the arc track, and is replaced by a steering platform with a simple structure and easy to manufacture. In this way, the aerial track system proposed by the present invention has a simple structure, low manufacturing cost and can make the entire track transportation system more compact and efficient.

[0013] In order to adapt to the above-mentioned aerial track without a reversing mechanism, the present invention also proposes a magnetic transport vehicle, which adopts a dual-motor and dual-drive wheel driving form with flexible steering and compact structure in terms of mechanical structure. At the same time, the magnetic transport vehicle is adsorbed on the aerial track through a strong magnetic suction cup; specifically, the drive wheels arranged on both sides of the magnetic transport vehicle rotate synchronously under the drive of their respective drive motors to drive the magnetic transport vehicle forward and reverse. When the driving route needs to be changed, the magnetic transport vehicle travels to the intersecting track section, and the drive wheels on both sides rotate at a differential speed to turn the vehicle body or even rotate 360 ​​degrees, thereby achieving the purpose of turning and reversing.

[0014] The magnetic transport vehicle further comprises universal balls, which are embedded around the bottom of the frame so that there is still a gap between the frame and the aerial track even in the magnetic adsorption state.

[0015] The strong magnetic suction cup of the magnetic suction transport vehicle can be a permanent magnetic suction cup, which is neither charged nor requires power supply; the suction force can be adjusted by increasing or decreasing the distance between the permanent magnetic suction cup and the track.

[0016] On the basis of the above, the magnetic suction transport vehicle proposed by the present invention further has the functions of "intelligence" and "automation", as follows:

[0017] It also includes a wireless communication module, which is connected to the vehicle control chip via a data cable. The vehicle control chip uses the wireless communication module to interact and transmit data with the background data control center in real time. The data includes vehicle location, driving path, speed, estimated arrival time, load weight, and mission plan.

[0018] RFID electronic tags with point information are arranged at intervals on the aerial track line, and an RFID electronic tag reading module is arranged on the magnetic suction transport vehicle. The RFID electronic tag reading module is connected to the vehicle control chip, so that when the vehicle passes by, it reads the RFID electronic tag on the aerial track line to identify its own position information, thereby facilitating timely adjustment of driving parameters, steering or parking.

[0019] Based on the above-mentioned communication module and the background data interaction network, the magnetic suction transport vehicle proposed in the present invention can operate according to the preset task plan independently without the need for real-time human intervention.

[0020] On the basis of the above, in order to improve the operating efficiency between the magnetic transport vehicle and the aerial track, sliding electrodes are installed at the four corners of the bottom of the magnetic transport vehicle. In this way, when the magnetic transport vehicle contacts the charged track electrodes, the battery is intermittently charged quickly.

[0021] Furthermore, there are two specific ways to charge the magnetic transport vehicle. One is that when the vehicle is moving, the electrode pops out and contacts the charged aerial track, and low-current and low-power charging is performed. For safety reasons, high-current and high-power charging when the vehicle is moving will not only generate electric sparks, but also accelerate the erosion of electrode contacts and charged tracks. The other is that when the vehicle arrives at the work station and stops, a short-term high-current and high-power fast charging is performed.

[0022] On the basis of the above, in order to make the automatic operation between the magnetic transport vehicle and the aerial track proposed by the present invention stable and reliable, the present invention adds a number of detection components to the magnetic transport vehicle and connects them to the control chip of the magnetic transport vehicle, thereby improving the operation stability of the magnetic transport vehicle. Specifically, its implementation method is as follows:

[0023] 1. The magnetic transport vehicle is provided with a proximity sensor at the bottom, and the proximity sensor is connected to the vehicle control chip through a data line. When the magnetic transport vehicle is traveling on the aerial track, the proximity sensor detects the deviation value of the ferromagnetic aerial track from the magnetic transport workshop in real time. When it is detected that the deviation value is too large, the vehicle control chip controls the differential action of the drive motor and corrects the driving route. If the detection value is zero, it may be that the proximity switch is damaged or the vehicle is at risk of running off the track, then the magnetic transport vehicle stops driving, thereby preventing the magnetic transport vehicle from running off or falling off the track.

[0024] 2. The magnetic transport vehicle is equipped with laser ranging sensors at the front and rear. The laser ranging sensors are connected to the vehicle control chip and are used to detect the following distance of the magnetic transport vehicle in front and behind. When it is detected that the following distance is too close, the vehicle control chip controls the motor to reduce the driving speed, so that the magnetic transport vehicle maintains a certain following safety distance to avoid rear-end collision.

[0025] With respect to the magnetic suction transport system proposed by the present invention, the present invention further discloses a specific method of using the magnetic suction transport system:

[0026] A method for using the magnetic suction transport system comprises the following steps:

[0027] Step 1: Lay the aerial track according to the design route and suspend it in the air indoors through screw hoisting or pillars and power it on, wherein the voltage on the aerial track is 36V;

[0028] Step 2: dock the magnetic transport vehicle to the aerial track and adsorb it on the aerial track, and at the same time, load the required cargo onto the magnetic transport vehicle;

[0029] Step 3: Sending a transport instruction from the background data control center to the vehicle control chip of the magnetic transport vehicle through the wireless communication module;

[0030] Step 4: The vehicle control chip drives the magnetic transport vehicle to travel according to the transport instructions, and checks and calibrates the transport track along the way by reading the RFID electronic tags on the aerial track;

[0031] Step 5: When the goods arrive at the destination according to the transportation instructions, remove the goods from the magnetic transport vehicle;

[0032] Step 6: The transportation process is completed, and the magnetic transport vehicle returns to the standby location according to the transportation instructions.

[0033] In the above-mentioned method of use, before the magnetic suction transport vehicle is loaded with goods and executes the transport instruction, it should be calculated whether its magnetic suction force meets the transport requirements to avoid the magnetic suction transport vehicle accidentally falling when executing the transport instruction. To avoid the occurrence of the above-mentioned situation, the present invention further proposes a safety calculation formula between the magnetic suction transport vehicle and the aerial track:

[0034] 1. When the strong magnetic chuck is a permanent magnet:

[0035]

[0036] Where F is the suction force, (BH)max is the magnetic energy product, A is the surface area of ​​the magnet, d is the distance between the magnet and the track, and k is a constant of the magnet shape, magnetic field distribution, and track material;

[0037] 2. When the strong magnetic chuck is an electromagnet:

[0038]

[0039] Where N is the number of turns in the coil, I is the current in the coil, A is the pole area, g is the air gap, i.e. the distance between the magnet and the track, and μ0 is the magnetic permeability of the vacuum.

[0040] In summary, the magnetic transportation system and its use method proposed in the present invention improve the efficiency of rail vehicle transportation and passage, while simplifying the structure of the supporting track, reducing the cost of track laying, and are suitable for application scenarios with complex and staggered track paths and a large number of stations, such as warehousing, logistics, sorting, inspection, etc. Furthermore, the highly integrated and compact design of the present invention can realize automatic control, save a lot of hardware manufacturing costs, improve operating efficiency, and reduce labor intensity and labor costs.

The cross track segment includes a platform 3 and a track extension segment 4 arranged around the platform 3, and the track extension segment 4 is used to be spliced ​​with the straight track segment 1.

[0049] The above-mentioned aerial track without a reversing mechanism, the straight track section 1 and the cross track section are all made of plate-shaped magnetic metal profiles.

[0050] Further, as an adapter component of the above-mentioned aerial track without a reversing mechanism, the magnetic suction transport vehicle 2 is specifically as follows:

[0051] like Figure 2 , Figure 3-4 As shown, it includes a frame 5, a vehicle control chip, a drive motor 6 and a battery arranged on both sides of the middle of the frame 5, and also includes a drive wheel 7 connected to the drive motor 6 and located on the left and right sides of the frame 5. A strong magnetic suction cup 8 is provided on the frame 5. The strong magnetic suction cup 8 is used to adsorb the entire magnetic suction transport vehicle 2 on the aerial track. The drive wheel 7 is used to drive the entire magnetic suction transport vehicle to travel on the aerial track. The battery serves as a power source to power the entire magnetic suction transport vehicle 2. The drive motor 6 and the battery are connected to the vehicle control chip through a data cable and a power cable and are controlled by the vehicle chip; it also includes a universal ball 9, which is embedded around the bottom of the frame 5 so that even in the magnetic adsorption state, the frame 5 still has a gap with the aerial track.

[0052] The above-mentioned magnetic transport vehicle 2, through the driving wheels 7 arranged on both sides of the magnetic transport vehicle 2, is driven by respective driving motors 6 to rotate synchronously to drive the magnetic transport vehicle 2 forward and reverse. When the driving route needs to be changed, the magnetic transport vehicle 2 travels to the intersecting track section, and the driving wheels 7 on both sides rotate at a differential speed to turn the vehicle body or even make a 360-degree rotation, thereby achieving the purpose of turning and reversing.

[0053] In this embodiment, the strong magnetic suction cup 8 is a permanent magnetic suction cup, which is neither charged nor requires power supply; the suction force can be adjusted by increasing or decreasing the distance between the permanent magnetic suction cup and the track.

[0054] The above-mentioned magnetic transport vehicle further has the functions of "intelligence" and "automation": it also includes a wireless communication module, which is connected to the vehicle control chip through a data cable. The vehicle control chip uses the wireless communication module to interact and transmit data with the background data control center in real time. The data includes vehicle location, driving path, speed, estimated arrival time, load weight, and mission plan.

[0055] RFID electronic tags with point information are arranged at intervals on the aerial track line, and an RFID electronic tag reading module is arranged on the magnetic suction transport vehicle 2. The RFID electronic tag reading module is connected to the vehicle control chip, so that when the vehicle passes by, it reads the RFID electronic tag on the aerial track line to identify its own position information, thereby facilitating timely adjustment of driving parameters, steering or parking.

[0056] Based on the above-mentioned communication module and the background data interaction network, the magnetic suction transport vehicle proposed in the present invention can operate according to the preset task plan independently without the need for real-time human intervention.

[0057] On the basis of the above, in order to improve the operating efficiency between the magnetic transport vehicle 2 and the aerial track, the magnetic transport vehicle 2 is equipped with sliding contact electrodes 12 at the four corners of the bottom, so that when the magnetic transport vehicle 2 contacts the charged track electrodes, the battery is intermittently charged quickly.

[0058] In the specific implementation process, there are two specific charging methods for the magnetic transport vehicle. One is that when the vehicle mentioned in this embodiment is moving, the electrode pops out and contacts the charged aerial track, and low-current and low-power charging is performed. For safety reasons, because the high-current and high-power charging vehicle will not only generate electric sparks when moving, but also accelerate the erosion of the electrode contacts and the charged track, resulting in a reduction in service life and maintenance cycle. The other is a charging method that is not mentioned in this embodiment but can also be implemented: when the vehicle arrives at the work station and stops, a short-term high-current and high-power fast charging is performed.

[0059] On the basis of the above, in order to make the automatic operation between the magnetic transport vehicle 2 and the aerial track proposed by the present invention stable and reliable, the present invention adds a number of detection components to the magnetic transport vehicle and connects them to the control chip of the magnetic transport vehicle 2, thereby improving the operation stability of the magnetic transport vehicle 2.

When it is detected that the deviation value is too large, the vehicle control chip controls the differential action of the drive motor and corrects the driving route. If the detected value is zero, it may be that the proximity switch is damaged or the vehicle is at risk of running off the track, then the magnetic transport vehicle stops driving, thereby preventing the magnetic transport vehicle from running off or falling off the track.

[0061] 2. The magnetic transport vehicle 2 is equipped with laser ranging sensors 10 at the front and rear. The laser ranging sensors 10 are connected to the vehicle control chip and are used to detect the following distance of the magnetic transport vehicle 2. When it is detected that the following distance is too close, the vehicle control chip controls the motor to reduce the driving speed, so that the magnetic transport vehicle 2 maintains a certain following safety distance to avoid rear-end collision.
