Description

Technical Field

[0001] The invention relates to a cargo loading and unloading system. Background Art

[0002] Currently, there are two main methods for loading and unloading goods in bags, barrels, and boxes: (1) semi-automatic loading and unloading by forklifts, which requires the installation of loading platforms, ramps, and other facilities; and (2) purely manual loading and unloading.

[0003] Taking a 30-ton flatbed truck or a 40-foot container as an example, it takes 30 to 40 minutes for a forklift to complete loading and unloading, and 1.5 to 2 hours to complete the loading and unloading manually. The cross-operation of personnel, forklifts and transport vehicles is more prone to safety and work-related accidents.

[0004] In summary, the prior art has the following deficiencies:

[0005] 1. The automation level and efficiency of loading and unloading vehicles are low;

[0006] 2. Multiple operators are required, and the labor cost is high;

[0007] 3. The operation safety factor is low;

[0008] 4. Loading time is long;

[0014] A vehicle-mounted conveyor, used for loading and unloading goods between the movable conveying platform;

[0015] A docking device, correspondingly arranged between the movable conveying platform and the docking end and / or docking side of the vehicle-mounted conveyor;

[0016] A variable frequency transmission mechanism, arranged on the movable transmission platform and the vehicle-mounted transmission machine, and used for transferring goods between the movable transmission platform and the vehicle-mounted transmission machine;

[0017] A vehicle-mounted limit switch, arranged on the movable conveying platform and the vehicle-mounted conveyor, is used to confirm whether the loading or unloading of goods is completed;

[0018] A locking device, arranged on the vehicle-mounted conveyor, for securing the cargo;

[0019] The control unit is connected with the movable conveying platform, the docking device, the frequency conversion conveying mechanism, the vehicle-mounted limit switch and the locking device through signals to control the automatic operation of the entire system.

[0020] The movable multi-directional rapid loading and unloading system is characterized in that: an infrared or laser alignment facility is arranged on the movable conveying platform to realize automatic and accurate docking with the vehicle-mounted conveyor.

[0021] The movable multi-directional rapid loading and unloading system, wherein: the terminal of the frequency conversion transmission mechanism is a transmission roller.

[0022] The movable multi-directional rapid loading and unloading system, wherein: the connecting device is a coupler.

[0023] The movable multi-directional rapid loading and unloading system, wherein: the locking device is an electric gate.

[0024] The advantages of the present invention are:

[0025] 1. Improve the efficiency and automation level of cargo loading and unloading;

[0026] 2. Reduce the number of operators and reduce labor costs;

[0027] 3. Improve the safety factor of operation;

[0028] 4. Compress the loading and unloading time to 3 to 5 minutes;

[0029] 5. Improve the turnover speed of transport vehicles;

[0030] 6. Reduce investment and maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the present invention provides a movable multi-directional rapid loading and unloading system, which mainly includes:

[0034] The movable conveying platform 1 has a motor or hydraulic drive device at the bottom, which can be moved left and right, front and back, and adjusted up and down;

[0035] The vehicle-mounted conveyor 4 is used to receive goods from the movable conveying platform 1 (loading) or unload goods to the movable conveying platform 1 (unloading); infrared or laser alignment facilities can be configured on the movable conveying platform 1 to achieve automatic and accurate docking with the vehicle-mounted conveyor 4;

[0036] The docking device 2 is arranged between the docking end and / or docking side of the movable conveying platform 1 and the vehicle-mounted conveyor 4. The docking device 2 can be a hook used for connecting train carriages, for example, and can be locked or disengaged through electrical control to achieve connection or disconnection between the movable conveying platform 1 and the vehicle-mounted conveyor 4. In the connected state, traction and impact force can be transmitted;

[0037] The variable frequency transmission mechanism 3 is arranged on the movable transmission platform 1 and the vehicle-mounted conveyor 4, and preferably adopts a transmission roller structure, and is used to transfer goods between the movable transmission platform 1 and the vehicle-mounted conveyor 4; in this embodiment, part of the variable frequency transmission mechanism 3 is used to transmit goods in the side direction, and part of the variable frequency transmission mechanism 3 is used to transmit goods in the head-to-tail direction. The transmission rollers in the side direction and the transmission rollers in the head-to-tail direction will be alternately raised a little during operation to avoid interference;

[0038] The vehicle-mounted limit switch 5 (or travel switch, position switch) is arranged on the movable conveying platform 1 and the vehicle-mounted conveyor 4 to confirm whether the loading or unloading of goods is completed to ensure the safety of the operation;

[0039] A locking device 6, arranged on the vehicle-mounted conveyor 4, for fixing the goods;

[0040] The control unit 7 is signal-connected with the movable conveying platform 1, the docking device 2, the frequency conversion conveying mechanism 3, the vehicle-mounted limit switch 5 and the locking device 6 to control the automatic operation of the entire system.

[0041] When loading a vehicle according to the present invention: bagged or barreled goods from upstream enter the movable conveying platform 1 in advance through the conveying equipment, the vehicle-mounted conveyor 4 enters the berth, and is locked by the docking device 2 after the side or tail is docked with the movable conveying platform 1, and the control unit 7 starts the frequency conversion transmission mechanism 3 on the movable conveying platform 1, and all the goods are simultaneously transmitted to the vehicle-mounted conveyor 4, and the limit switch 5 on the vehicle-mounted conveyor 4 is triggered to determine that the loading is completed, the spring starts the locking device 6 to fix the goods, and finally the docking device 2 is disengaged, and the vehicle-mounted conveyor 4 drives out with full load.

[0042] Unloading is the reverse operation process of loading: the vehicle-mounted conveyor 4 enters the berth, and is locked by the docking device 2 after docking with the movable conveying platform 1 at the side or tail. The locking device 6 is disengaged, and the control unit 7 starts the frequency conversion transmission mechanism 3 on the vehicle-mounted conveyor 4 to simultaneously transfer all the goods from the vehicle-mounted conveyor 4 to the movable conveying platform 1. The limit switch 5 on the movable conveying platform 1 is triggered to determine that the unloading is completed, and finally the docking device 2 is disengaged, and the vehicle-mounted conveyor 4 drives out empty.

[0043] The above description is only illustrative rather than restrictive of the present invention. Those skilled in the art will understand that many modifications, changes or equivalents may be made without departing from the spirit and scope defined by the claims, but all will fall within the scope of protection of the present invention.
