Description

Technical Field

[0001] This utility model relates to the technical field of automatic loading and unloading vehicles, specifically a heavy-duty column mobile chassis for a single-column double-arm automatic loading and unloading vehicle. Background Technology

[0002] Box truck transportation is one of the main modes of transport in the logistics industry, known for its safety and efficiency; its share will continue to increase with the rapid development of logistics in my country. Due to the unique structure of box trucks—such as variations in cargo height and internal dimensions among different models—and the fact that they operate in a semi-enclosed space, achieving automated loading and unloading is extremely difficult. Currently, box truck loading and unloading is mainly done manually and with the aid of conveyor belts or electric forklifts. Manual labor suffers from low efficiency, high intensity, and high cost. Electric forklifts can reduce manual labor intensity, but they cannot fully utilize the cargo space inside the box and cannot completely eliminate manual labor. With rising labor costs, replacing manual loading and unloading with machines is an inevitable trend. However, existing automated loading and unloading platforms cannot transport or adjust the posture of boxes that need to be stacked, requiring external box conveying equipment for docking, which is inconvenient for loading and unloading. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a heavy-duty column mobile chassis for automatic loading and unloading vehicles with a single column and double arms.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model discloses a heavy-duty column mobile chassis for automatic loading and unloading vehicles with a single column and two arms. It includes a base with a tracked walker at the bottom, a vertically upward column at the front end of the base, and lifting seats mounted on the opposite sides of the column via a multi-stage lifting mechanism. Each lifting seat is equipped with an independently operated loading and unloading robotic arm. The base has a feed telescopic roller conveyor at its end, and a material distribution mechanism that connects to the feed telescopic roller conveyor is also provided on the base. The end of the material distribution mechanism is connected to a tilting mechanism for adjusting the posture of the container. The base also has corresponding grabbing stations that connect to the tilting mechanism and correspond one-to-one with the loading and unloading robotic arms.

[0006] As a preferred embodiment of this utility model, the material feeding and separating mechanism includes a first roller conveyor on the base, and feeding roller conveyors are provided on both sides of the first roller conveyor. The feeding roller conveyors are aligned with and parallel to the first roller conveyor. The base is provided with a pushing mechanism for pushing the box on the first roller conveyor toward the feeding pipes on both sides. The pushing mechanism includes a pair of parallel optical rods on the base. Each optical rod is provided with two sliders.

[0015] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0016] Example: Figure 1 , Figure 2 As shown, this utility model discloses a heavy-duty column mobile chassis for automatic loading and unloading vehicles with a single column and two arms. It includes a base 1 with a tracked walker at the bottom, a vertically upward column 2 at the front end of the base 1, and lifting seats 4 mounted on the opposite sides of the column 2 via multi-stage lifting mechanisms 3. Each lifting seat 4 is equipped with an independently operated loading and unloading robotic arm 5. The base 1 has an infeed telescopic roller conveyor 6 at its end, and an infeed channeling mechanism 7 that connects to the infeed telescopic roller conveyor 6. The infeed channeling mechanism 7 is connected to a flipping mechanism 8 at its end. The flipping mechanism 8 is used to adjust the posture of the container. The base 1 also has a grabbing station 9 that connects to the flipping mechanism 8 and corresponds one-to-one with the loading and unloading robotic arm 5. This allows the container to be transported to the corresponding roller conveyor according to its posture. When the container's posture is incorrect, the flipping mechanism 8 flips it.

[0017] The material feeding mechanism 7 includes a first roller conveyor 701 on the base 1, and feeding roller conveyors 702 are provided on both sides of the first roller conveyor 701. The feeding roller conveyors 702 are aligned with and parallel to the first roller conveyor 701. The base 1 is provided with a pushing mechanism for pushing the box on the first roller conveyor 701 toward the feeding pipes on both sides. The pushing mechanism includes a pair of parallel optical rods 703 on the base 1. Each optical rod 703 is provided with two sliders 704. A pair of parallel movable frames 705 are provided between blocks 704, and each movable frame 705 is provided with multiple push rods 706 inserted into the gap between the first roller conveyor 701 and the feeding roller conveyor 702. The base 1 is provided with a material distribution mechanism that drives the movable frames 705 to move. The feed telescopic roller line 6 sends the box into the material distribution mechanism 7. If the box is in the correct position, the movable frame is driven to move left and right by the transmission belt, thereby dividing the roller conveyors on both sides of the box, which facilitates the operation of the robotic arm.

[0018] The material distribution mechanism includes two pulleys 707 mounted on the base 1, with a transmission belt 708 sleeved between the pulleys 707. The movable frame 705 is fixed to the transmission belt 708 by a positioning component. The base 1 is equipped with a transmission motor that drives the pulleys 707 to rotate. The movable frame is moved by the transmission belt, which has the characteristic of fast response.

[0019] The flipping mechanism 8 includes a flipping roller conveyor 801 mounted on the base 1, with docking roller conveyors 802 on both sides of the flipping roller conveyor 801. A steering mechanism is also provided on both sides of the flipping roller conveyor 801. The steering mechanism includes a rotating shaft 803 mounted on the base and located on the roller conveyor. A cross-shaped flipping frame 804 is mounted on the rotating shaft 803, inserted into the gap between the rollers of the flipping roller conveyor 801 and rotating towards the docking roller conveyor 802. The cross-shaped flipping frame 804 supports the bottom of the box and flips the box towards the docking roller conveyor 802 as the rotating shaft 803 rotates. A flipping motor is mounted on the base 1 to drive the rotating shaft 803. When adjusting the posture of the box, the rotating shaft drives the cross-shaped flipping frame 804 to flip, thus supporting the bottom of the box and flipping it towards the docking roller conveyor 802 as the rotating shaft rotates, thereby achieving posture adjustment. The drive motor and the tilting motor are both servo motors, which makes them easy to control.

[0020] Working principle: First, the feeding telescopic roller conveyor 6 feeds the box into the incoming material distribution mechanism 7. If the box's posture is correct and no adjustment is needed, the pushing mechanism in the incoming material distribution mechanism 7 operates, driving the moving frame 705 to move left and right via the transmission belt 708, thus diverting the box to the feeding roller conveyors 702 on both sides. Then, the feeding roller conveyors 702 feed the box into the docking roller conveyor 802, and finally into the waiting gripping position 9. When the box needs posture adjustment, the first roller conveyor 701 feeds the box into the flipping roller conveyor 801. Then, when adjusting the box's posture, the rotating shaft 803 drives the cross-shaped flipping frame 804 to flip. The cross-shaped flipping frame 804 supports the bottom of the box and flips it with the rotating shaft 803 to the docking roller conveyor 802, thus achieving posture adjustment, and finally sending it into the waiting gripping position 9.

[0021] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
