Description

Technical Field

[0001] This invention relates to the field of container unloading control, and more particularly to a control system for intelligent transfer equipment for whole-vehicle cargo in truck containers. Background Technology

[0002] Due to the complex arrangement of goods inside truck containers and the intricate structure of the containers themselves, goods are difficult to unload as a whole, resulting in long waiting times for truck unloading and reduced cargo transfer efficiency. Currently, unloading operations are mainly manual. The general workflow is as follows: unloading personnel open the container doors, enter the container to unload, transfer the goods to the outside via conveyor belt or forklift, and then use trolleys to transfer them to the next work location. This method of operation requires too many personnel, has low unloading efficiency, and poses a significant threat to the safety of the workers. Summary of the Invention

[0003] To address the problems existing in the prior art, this invention discloses a control system for intelligent cargo transfer equipment applied to truck containers, comprising a central control unit, a cargo transfer unit, a tiered unloading platform, a cargo diversion unit, a cargo disinfection unit, and a palletizing unit. The cargo transfer unit transfers the cargo inside the truck compartment to the tiered unloading platform, which then dumps the cargo in layers to the cargo diversion unit. The cargo diversion unit further sorts and diverts the cargo, controlling its orderly entry into the cargo disinfection unit. The cargo disinfection unit inactivates bacteria on the surface of the cargo. The palletizing unit arranges the inactivated cargo as a whole. The central control unit performs real-time control over the operation of the cargo transfer unit, the tiered unloading platform, the cargo diversion unit, the cargo disinfection unit, and the palletizing unit.

[0004] Furthermore, the central control unit includes a main control chip, a wireless remote control module, and a component control module. The wireless remote control module is connected to the main control chip and is used to remotely control the working status of the cargo diversion unit, the cargo disinfection unit, and the palletizing robot. The component control module is connected to the main control chip and is used to directly control the position and orientation of the whole vehicle cargo transfer unit and the layered unloading platform.

[0005] Furthermore, the vehicle cargo transfer unit includes a vehicle unloading slide, an unloading rail, an unloading slide motor, a cargo lifting hydraulic cylinder, and a laser rangefinder. The laser rangefinder is installed at the front end of the vehicle unloading slide and is used to detect the real-time travel of the vehicle unloading slide and transmit the detected data to the main control chip. The central control unit controls the vehicle unloading slide to move along the unloading rail by controlling the unloading slide motor. The cargo lifting hydraulic cylinder is used to lift the cargo pallet and control the overall movement of the cargo pallet out of the truck container.

[0006] Furthermore, the layered unloading platform includes a tilting platform, a lifting door, a camera device, a laser rangefinder, an inclination sensor, and a follow-up lifting conveyor belt. The camera device and laser rangefinder are used to monitor the height information of the goods and transmit it to the main control chip. The inclination sensor is used to measure the angle information of the tilting platform in real time and transmit it to the main control chip. The central control unit controls the tilting angle of the tilting platform and controls the height of the lifting door by adjusting the lifting height of the slide. The tilting platform is used to adjust the tilting angle of the cargo pallet, control the cargo to slide to the lifting door and be transported to the cargo diversion unit. The follow-up lifting conveyor belt moves up and down synchronously with the lifting door.

[0007] Furthermore, the cargo diversion unit includes a cargo diversion conveyor belt, a pressure sensor, a power supply switch for the diversion system, and a wireless control transmission module. The pressure sensor is installed above the cargo diversion conveyor belt and is used to detect the weight information of the cargo. The central control unit controls the operation of the diversion system in real time by controlling the on / off state of the power supply switch for the diversion system. The cargo diversion conveyor belt diverts the cargo from the self-layering unloading platform to ensure that the cargo passes through evenly and orderly.

[0008] Furthermore, the cargo disinfection unit includes a cargo disinfection device, a cargo disinfection system power switch, and a wireless control transmission module. The cargo disinfection device extinguishes viruses on the surface of the cargo, and the cargo disinfection system power switch and its wireless transmission module are used to remotely control whether the cargo disinfection system is working.

[0009] Furthermore, the palletizing unit includes a camera, a power switch for the palletizing system, a palletizing robot, and its wireless control and transmission module; the camera is used to monitor the operation of the palletizing unit and transmit the monitored image information to the main control chip; the power switch for the palletizing system remotely controls the working process of the palletizing system; and the palletizing robot and its wireless control and transmission module are used to remotely control the working behavior and status of the palletizing robot.

[0010] By employing the above-mentioned technical solution, this invention provides a control system for intelligent cargo transfer equipment applied to truck containers. This system utilizes the coordinated operation of a central control unit, a cargo transfer unit, a layered unloading platform, a cargo diversion unit, and a cargo disinfection unit. Each sub-unit is interconnected yet operates independently, achieving efficient and continuous unloading operations. Compared to traditional unloading methods, by applying the cargo transfer unit, the cargo inside the truck is unloaded as a whole, significantly reducing truck unloading waiting time and further improving unloading efficiency. This system further automates cargo transfer operations by using sensors such as cameras and pressure sensors, facilitating automated assembly line operations in factories. Integrating the control system into the central control unit simplifies operator control of the workflow and reduces the operational complexity of the control system. Attached Figure Description

[0015] To make the technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention:

[0016] like Figure 1 The control system of an intelligent cargo transfer system for truck containers, as shown, includes a central control unit, a cargo transfer unit, a tiered unloading platform, a cargo diversion unit, a cargo disinfection unit, and a palletizing unit. The cargo transfer unit transfers the cargo from inside the truck bed to the tiered unloading platform. The tiered unloading platform then dumps the cargo in layers to the cargo diversion unit, preventing damage from large-scale dumping. The cargo diversion unit further sorts and diverts the cargo, ensuring it enters the cargo disinfection unit in an orderly manner. The cargo disinfection unit inactivates bacteria on the cargo surface, preventing viral infection. The palletizing unit arranges the inactivated cargo neatly for easy transfer to the next processing step. The central control unit receives sensor signals from each unit and controls the operation of each unit according to pre-set parameters.

[0017] Furthermore, such as Figure 2 and Figure 3As shown, the central control unit controls the operation of the truck cargo transfer unit and the tiered unloading platform via built-in wiring, and controls the cargo diversion unit, cargo disinfection unit, and palletizing unit via wireless signals. Cameras monitor the truck's parking position in real time, and the height of the tiered unloading platform is adjusted accordingly to allow the truck cargo transfer unit to move the entire truckload of cargo onto the platform. Tilt sensors and cameras monitor the tilt angle and unloading status of the tiered unloading platform in real time, and the tilt angle and lifting door height are controlled to allow the cargo to tilt out of the platform under gravity. Pressure sensors measure cargo weight; upon detection, the cargo diversion and disinfection units activate, arranging and diverting the cargo and inactivating viruses on its surface. Cameras monitor the palletizing robot's actions in real time. This system is simple to control, allows for continuous operation, and effectively improves the economy and efficiency of truck container unloading operations.

[0018] In this system, the central control unit controls the rotation of the lifting motor driven by the slide table, which in turn controls the height of the unloading lifting door. By using the analog input information from the laser rangefinder, the current travel of the cargo, the lifting door, and the unloading slide of the whole vehicle can be accurately obtained, and the height of the lifting door and the position of the unloading slide of the whole vehicle can be further adjusted.

[0019] Furthermore, the central control unit includes a main control chip, a wireless remote control module, and a component control module. The wireless remote control module is connected to the main control chip and is used to remotely control the working status of the cargo diversion unit, the cargo disinfection unit, and the palletizing unit. The component control module is connected to the main control chip and is used to directly control the position and orientation of the whole vehicle cargo transfer unit and the layered unloading platform.

[0020] Furthermore, the vehicle cargo transfer unit includes a vehicle unloading slide, an unloading rail, an unloading slide motor, a cargo lifting hydraulic cylinder, and a laser rangefinder. The laser rangefinder is installed at the front end of the vehicle unloading slide to detect the real-time travel of the vehicle unloading slide and transmit the detected data to the main control chip. The central control unit controls the unloading slide motor to move the vehicle unloading slide along the unloading rail. The cargo lifting hydraulic cylinder is used to lift the cargo pallet and move the cargo pallet out of the truck container as a whole.

[0021] Furthermore, the tiered unloading platform includes a tilting platform, a lifting door, a camera device, a laser rangefinder, an inclination sensor, and a follow-up lifting conveyor belt. The laser rangefinder monitors the height information of the goods and transmits it to the main control chip. The camera device records the unloading operation and transmits the image signal to the main control chip. The inclination sensor measures the angle information of the tilting platform in real time and transmits it to the main control chip. The central control unit controls the tilt angle of the tilting platform and controls the height of the lifting door by adjusting the lifting height of the slide. The tilting platform adjusts the tilt angle of the cargo pallet, controls the goods to slide to the lifting door, and transports them to the cargo distribution unit in tiers. The follow-up lifting conveyor belt moves synchronously with the lifting door, allowing the goods to slide to the cargo distribution unit and preventing the goods from falling from a height and being damaged.

[0022] Furthermore, the cargo diversion unit includes a cargo diversion conveyor belt, a pressure sensor, a power supply switch for the diversion system, and a wireless control transmission module. The pressure sensor is installed above the cargo diversion conveyor belt and is used to detect the weight information of the cargo. The central control unit controls the operation of the diversion system in real time by controlling the on / off state of the power supply switch for the diversion system. The cargo diversion conveyor belt diverts the cargo from the layered unloading platform to ensure that the cargo passes through evenly and orderly.

[0023] Furthermore, the cargo disinfection unit includes a cargo disinfection device, a cargo disinfection system power switch, and a wireless control and transmission module. The cargo disinfection device inactivates viruses on the surface of the cargo, and the cargo disinfection system power switch and its wireless transmission module are used to remotely control whether the cargo disinfection system is working.

[0024] Furthermore, the palletizing unit includes a camera, a power switch for the palletizing system, a palletizing robot, and its wireless control and transmission module; the camera is used to monitor the operation of the palletizing unit and transmit the monitored image information to the main control chip; the power switch for the palletizing system remotely controls whether the palletizing system is operating; and the palletizing robot and its wireless control and transmission module are used to remotely control the working behavior and status of the palletizing robot.

[0025] The system disclosed in this invention employs the following steps during unloading:

[0026] The truck to be unloaded is parked at the designated parking point. The tilting platform adjusts its position, and the unloading slide moves along the unloading rails and enters under the cargo pallet. The tilting platform, in conjunction with the cargo lifting hydraulic cylinders, drives the unloading slide to lift the cargo pallet upwards. Once the cargo pallet is lifted to a certain height, the unloading slide returns to the tilting platform carrying the cargo and pallet. The height of the lifting gate is adjusted, and the tilting angle of the tilting platform is controlled to ensure that the cargo is transferred in layers and in an orderly manner along the following lifting conveyor belt to the cargo diversion conveyor belt. When the pressure sensor detects the weight of the cargo, the cargo diversion conveyor belt begins its diversion operation. The cargo is transported to the cargo disinfection device via the diversion conveyor belt. After disinfection, the palletizing robot arranges the cargo neatly, awaiting the next processing step.

[0027] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
