[0002] In the rapidly developing modern logistics industry, efficient and accurate cargo loading and unloading operations are of great significance to improving overall logistics efficiency and reducing costs. In traditional technology, the logistics loading and unloading process mainly relies on manual operation, which is not only labor-intensive, but also relatively inefficient and easily affected by human factors such as fatigue and operating proficiency, resulting in damage to goods, uneven stacking and other problems during the loading and unloading process. In order to meet this challenge, some automated or semi-automated loading and unloading systems have gradually appeared on the market, attempting to reduce the labor burden and improve loading and unloading efficiency through mechanized means. However, most of these systems are single-function, lack sufficient intelligence and flexibility, and are difficult to adapt to complex and changeable logistics scenarios. For example, some existing automated loading and unloading equipment can only complete simple handling or stacking tasks, and complex operations such as reversing, sorting, and merging of goods still require manual assistance, and have not been able to truly achieve full automation of loading and unloading operations. For this reason, the present invention proposes an intelligent loading and unloading vehicle system. Summary of the invention

[0042] In summary, the workflow of loading and unloading from one layer to the top layer in actual use of the present invention is as follows: the box body is first sent to the roller conveyor device 2 through the front-end device; after the box body is in place, the first-stage roller machine 21 stops conveying, and the reversing box pushing device 3 pushes the box body to the right channel; after the reversing box pushing device 3 pushes the box body into place, the first-stage roller machine 21, the second-stage roller machine 22, and the third-stage roller machine 23 work to convey the box body to the box combining station in place; the third-stage roller machine 23 stops working, and the box combining device 6 pushes the box body into place; when the next box is received, the first-stage roller machine 21, the second-stage roller machine 22, and the third-stage roller machine 23 are re-operated. Repeat the above steps; the first roller machine 21 stops conveying, and the reversing box pushing device 3 pushes the box to the right channel; after the reversing box pushing device 3 pushes the box into place, the first roller machine 21, the second roller machine 22, and the third roller machine 23 work to convey the box to the box combining position; the third roller machine 23 stops working, and the box combining device 6 pushes the box into place; after the double boxes are in place, the left and right robot devices 7 take the double boxes through the suction cup device 8 to load them from the first layer to the second top layer; for vertical loading on the top layer, the robot device 7 takes the double boxes The boxes are transferred to the double-station module platform 11; the double-station module platform 11 is raised to the loading height; the robot device 7 pushes the double boxes on the module platform to the top-level station; and so on to complete the top-level loading process; the top level is flat loading, and the boxes are sent to the roller conveyor device 2 through the front-end device; after the boxes are in place, the first-stage roller machine 21 stops conveying, the reversing box-pushing device 3 pushes the boxes to the right channel, and the box-blocking device 4 rises; after the reversing box-pushing device 3 pushes the boxes into place, the first-stage roller machine 21 and the second-stage roller machine 22 work to move the boxes The box is transported to the case turning station and put into position; after the box is in position, the second-stage roller machine 22 stops, and the cross case turning device 5 works to lay the box flat; after the box is laid flat, the second-stage roller machine 22 and the third-stage roller machine 23 work to transport the flat box to the case combining station; the case combining device 6 positions the flat box to the case taking station of the robot device 7; the robot device 7 transports the flat box to the double-station module platform 11; the double-station module platform 11 rises, and the robot device 7 pushes the flat box to the stacking station; and so on to complete the top-level flat loading;

[0043] After the intelligent loading and unloading system has loaded one side of the box, the mobile platform 1 automatically moves backwards to continue loading the next side, and so on to complete the entire box loading process. The unloading process is the opposite of the loading process.

[0044] The electrical system in the intelligent loading and unloading vehicle system of the present invention includes an intelligent digital controller PAC, a servo control system, an IOLINK controller, a laser radar, an ultrasonic sensor, and a photoelectric switch; the core of the system adopts a multifunctional intelligent digital controller (PAC for short), which is based on the x86 computing platform and integrates PLC, HMI, motion control and visual functions, and is equipped with an Intel Core processor (Intel Core i series CPU), which provides a strong guarantee for the stability and diversity of the system; the PAC controller provides a variety of interfaces, including the EtherCAT interface, which connects all devices in series through a standard eight-core Ethernet cable. The series devices mainly include:

[0045] 1) Servo system.

[0046] All power systems, including roller conveyors, box turners, and lifting and feeding mechanisms, communicate via EtherCAT to achieve data interaction and servo synchronization between different servos, transmit all data to the PAC controller, and simultaneously receive relevant instructions from the PAC controller.

[0047] 2) EtherCAT splitter

[0048] The EtherCAT splitter is mainly used to expand the problem of insufficient branching of the EtherCAT interface. It can branch the communication lines in the EtherCAT network. Just like branching several small roads on a main road, it can easily connect multiple EtherCAT devices, such as connecting multiple slave devices (such as sensors, actuators, etc.), to achieve flexible device networking, expand the coverage of the network, and enhance the scalability of the system. Moreover, the splitter can ensure that the data transmission on each branch line follows the EtherCAT protocol standard, ensuring that the data is efficiently, stably and accurately exchanged between the master and slave stations.

[0049] 3) Distributed I / O

[0050] The PAC controller can collect and control related switch quantity data remotely through a distributed I / O controller with an EtherCAT interface.

[0051] 4) I / O LINK controller

[0052] The I / O LINK controller mainly collects relevant data from ultrasonic radar, laser ranging, and lidar, and then transmits the relevant data to the PAC controller through the EtherCAT communication port.

[0053] 1.4PAC control system provides two LAN Ethernet ports, namely LAN B and LAN C.

[0054] LAN B port exchanges data with the robot, visual inspection, and AGV car through a multi-port switch.

[0055] The LAN C port is connected to the external network through the gateway. The left protagonist in the architecture diagram is the remote cloud of the equipment manufacturer, which is mainly responsible for remote debugging and maintenance. The right side is the internal cloud of the user, which is mainly responsible for equipment monitoring and data collection.

[0056] PAC can realize remote display and control through KVM controller. The specific implementation method is: install a KVM controller transmitter in the electric cabinet on the trolley, and connect it to the PAC controller with HDMI cable and USB cable. At the remote end, install a display and a KVM controller receiver, and install the required mouse and keyboard on it. In this way, remote control of PAC is realized.

[0057] Because PAC has the functions of PLC, HMI, and motion control, making HMI screen on PAC can achieve high integration of equipment. That is, control, screen, and monitoring are integrated. In this way, through the remote screen projection of KVM, the functions of safe debugging, use, and monitoring are realized.

[0058] Automatic control process of electrical system:

[0059] Start working

[0060] When the car receives the signal to start working, the PAC controller will first retract the robot arm to a specific position, then send a photo request to the camera, and at the same time collect the laser ranging data at the front end of the car. After comprehensive processing, it will send the data required for walking to the AGV car.

[0061] When the AGV is moving, the 270-degree laser radar installed on the diagonal of the vehicle provides a 360-degree collision warning for the vehicle.

[0062] When the trolley moves to the specified position, the PAC controller sends a feeding request to the supplier (if unloading, it sends a discharging signal).

[0063] Material Handling

[0064] The entrance uses three SV660 high-precision servo motors to control the feeding rollers in three stages. When the incoming material is detected, the rollers start running. When the material is transported to the stopper of the No. 1 roller and the in-place detection switch is triggered, the push plate merges the carton into the right channel and feeds it into the No. 2 roller.

[0065] If a side box is needed, a stopper will rise between the second and third rollers to stop the material from moving forward and trigger the box turning servo action. If a box turning is not needed, the material will directly enter the third roller from the second roller.

[0066] The material enters the No. 3 roller and triggers the end-in-place signal. The left-side box servo starts and pushes the material to the right-side waiting area. When the right-side waiting area is full of two boxes of materials, the box servo clamps the left and right boxes at the same time to center the two boxes for easy material removal. After centering, the PAC controller sends a signal to the manipulator that the material is ready. The opposite is true when unloading.

[0067] Reclaim

[0068] When the robot receives the material ready signal, the left and right robots will perform cross operations in sequence according to the specified requirements. Every time the robot takes in a material, it will take a photo of the material with the visual camera on its arm to confirm the material coordinates (when unloading, it will take a photo to confirm the material location).

[0069] Palletizing

[0070] Palletizing is divided into two parts, namely base palletizing and top palletizing.

[0071] For base palletizing, the robot directly sucks the top of the box. When the vacuum generator detects that the vacuum value has been reached, it starts to suck the box and put it in the designated position. If the vacuum establishment signal is not detected within a certain period of time, the PAC triggers the alarm and the screen displays the alarm information. The order of palletizing is from the middle to both sides.

[0072] For top palletizing, the robot first places the box onto the lifting platform, and then waits for the lifting platform to reach the designated position before the robot pushes it into the designated workstation.

[0073] quit

[0074] When one side of the palletizing is completed, the palletizing trolley automatically moves back a specified distance and starts a new round of palletizing. This continues in turn until all the cartons are loaded.

[0075] Although embodiments of the present invention have been shown and described (see the above detailed description for details), it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
