[0026] The present disclosure is further described in detail below in conjunction with the accompanying drawings and implementations. It is understood that the specific implementations described herein are only used to explain the relevant content, rather than to limit the present disclosure. It should also be noted that, for ease of description, only the parts related to the present disclosure are shown in the accompanying drawings.

[0027] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure may be combined with each other. The present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0028] The present invention can realize the automation of the container loading and unloading process of the cargo moving vehicle. The present invention puts the container on the transition plate and sends it into the compartment cargo hold through program control, uses a steering mechanism to adjust the direction, and uses an adaptive transmission mechanism to transport the container, automatically locates it, and locks its position by a locking mechanism. Similarly, the container can also be automatically unloaded, greatly shortening the loading and unloading time of each vehicle; at the same time, after the container is in place, the system has a weighing instrument to measure the weight and record it in the RFID tag of the container, realizing the automatic loading and unloading of the cargo moving vehicle group container quickly, accurately, and unmanned operation; reducing the workload of manual labor and improving the efficiency of loading and unloading containers of cargo moving vehicles.

[0029] In an optional embodiment of the present disclosure, Figure 1 As shown, the integrated system for automatic loading and unloading of freight moving vehicles includes: a transition plate 1, which is used for transitional transportation of containers between the platform and the loading door; a transportation system 2, which is arranged in the compartment of the freight moving vehicle group, including a steering mechanism 21, a floor system 22, a transportation mechanism 23, and a locking mechanism 24; a storage system 3, which includes an RFID electronic tag 31, an RFID tag reader / writer 32, a PC server 33, an automatic weighing system 34 and an automatic positioning system 35; the RFID electronic tag 31 is arranged on the container, and the RFID tag reader / writer 32 and the PC server 33 are arranged in the compartment of the freight moving vehicle group.

[0030] In an optional embodiment of the present disclosure, Figure 2 As shown, after the container enters the loading door of the carriage from the transition plate 1, it is rotated 90 degrees forward or reverse by the steering mechanism 21, and with the assistance of the automatic positioning system (not shown), the container is delivered to the destination by the conveying mechanism 23 located on the floor system 22, and is locked by the locking mechanism 24, and automatic weighing is completed. The PC server (not shown) writes the location information and weight information of the container on the RFID electronic tag (not shown) through the RFID tag reader (not shown).

[0031] The structures of the various components of the integrated system for automatic loading and unloading of cargo moving vehicles are described in detail below with reference to the accompanying drawings.

[0032] The transition plate 1 disclosed in the present invention preferably adopts an aluminum honeycomb transition plate, which is equipped with the vehicle, and each loading door is equipped with a transition plate. The transition plate is fixed on the vehicle body by a suction cup through atmospheric pressure. In order to protect the door from collision with the container, guardrails are provided on both sides of the transition plate.

[0033] like Figure 3As shown, the floor system 22 of the present disclosure adopts a universal ball honeycomb floor, including an aluminum honeycomb panel 221 and a universal ball 222. A single universal ball can bear a weight of 200KG. The aluminum honeycomb floor is an aluminum honeycomb core made of 3A21H18 aluminum foil with a thickness of 0.07mm. The aluminum honeycomb panel is connected and fixed to the C-shaped groove of the vehicle body chassis through profiles and bolts.

[0034] like Figure 4 As shown, the conveying mechanism 23 of the present disclosure includes a first base 231, rollers 232 and a stepper motor 233. A plurality of rollers 232 are arranged at intervals on the first base 231. The stepper motor 233 is arranged in the first base 231. The rollers 232 are driven by the stepper motor 233. The rollers are rubber rollers, which are in contact with the bottom of the container and drag the container by the friction generated by the contact. To increase the friction, the outer surface of the rubber roller is designed to be striped.

[0035] The entire automatic loading and unloading integrated system is composed of multiple container automatic conveying mechanisms. In order to accurately control a certain conveying mechanism, a PLC controller is used. PLC is a programmable logic controller. It uses a type of programmable memory to store programs internally, execute user-oriented instructions such as logical operations, sequential control, timing, counting and arithmetic operations, and control various types of machinery or production processes through digital or analog input / output. It is easy to use, simple to program, powerful, high performance-price ratio, high reliability, strong anti-interference ability, complete hardware, user-friendly, strong adaptability, and less workload in system design, installation and debugging.

[0036] According to at least one embodiment of the present disclosure, the conveying mechanism further includes a sprocket transmission chain 234, and the two adjacent rollers are connected by the sprocket transmission chain. The sprocket transmission chain transmits power to the rubber roller. The sprocket transmission chain is characterized by long-distance transmission, high efficiency, and no slippage.

[0037] According to at least one embodiment of the present disclosure, the conveying mechanism further includes a lifting platform 235, and the two lifting platforms are respectively arranged below the two ends of the first base. The lifting platform adopts a scissor lift to achieve the lifting or lowering of the container.

[0038] like Figure 5As shown, the steering mechanism 21 of the present disclosure is composed of an upper support plate 211, a lower support plate 212, and a worm gear transmission mechanism 213. When the container is placed on the upper support plate, the control system will send a command to the motor of the worm gear transmission mechanism, and the worm gear mechanism will drive the upper support plate to rotate 90° forward or reverse. Preferably, the upper support plate adopts a universal ball honeycomb floor and is integrated with a conveying mechanism. When an emergency such as a power outage occurs, the lifting platform of the conveying mechanism can be manually used to lower the conveying mechanism. At this time, the universal ball can allow the container to be rotated manually.

[0039] like Figure 6 As shown, the automatic positioning system 35 of the present disclosure is a computer automatic positioning system based on high-precision subdivision of stepper motors, which is established on the basis of photoelectric sensors. This technology involves system technical solutions, measurement and elimination of azimuth deviations, and high-precision subdivision of stepper motors, and precise control of stepper motors, thereby achieving accurate control of the container position. The system mainly includes a right-angle reflection prism 351, a photoelectric sensor 352, a signal processing module 353, an A / D conversion circuit module 354, a PC server 33, an adjustable subdivision control module 355, and a stepper motor 233. After the right-angle reflection prism detects the container, the photoelectric sensor converts the optical signal into an electrical signal, which is processed by the signal processing module and the A / D conversion circuit module in turn, and then the PC server receives and processes the information, and the adjustable subdivision control module issues a control instruction to the stepper motor, thereby achieving accurate control of the container position.

[0040] like Figure 7 As shown, the locking mechanism 24 of the present invention includes a second base 241, a spring 242 and a claw head 243. The second base is arranged on the honeycomb plate, and the claw head is arranged on the second base through the spring. The claw head is L-shaped, and the retracted state of the claw head facilitates the unrestricted movement of the container on the second base. When the container is transported to the destination, under the action of the spring, the claw head changes from a retracted state to a relaxed state to complete the stop.

[0041] The automatic weighing system 34 disclosed in the present invention, also known as an unattended weighing system, can realize the weighing of multiple containers. The system can generate an EXCEL table with the container weight data and connect it with the intelligent warehouse entry and exit system through a computer. In the entire weighing process, the measurement data can be automatically and reliably collected, automatically judged, automatically directed, automatically processed, and automatically controlled, which minimizes the disadvantages and work intensity brought by manual operation and improves the informatization and automation of the system. The automatic weighing system adopts PLC as the control core to realize the basic control functions of the weighing instrument. The hardware part of the system includes three parts: application sensor, data acquisition and data processing, among which the data acquisition part is composed of a weighing instrument simulator, a pre-stage processing of the signal and a dual-integral A / D conversion part. Since the accuracy and anti-interference requirements of the circuit in the weighing instrument design are high, a high-precision instrument amplifier INA121 is selected.
