Description

Technical Field

[0001] This invention relates to the field of automated loading and unloading equipment for logistics, and more particularly to a continuous conveying type automated loading and unloading device. Background Technology

[0002] Currently, automated and intelligent hardware and software facilities are widely used in key logistics processes such as information, transportation, warehousing, handling, inventory, and packaging. However, loading and unloading remain largely manual, resulting in low efficiency. For example, a 40ft container typically contains 1500-3000 items, depending on product size and specifications. It takes approximately 3-4 hours for two loaders to load and unload one container, which, without considering sorting time, is insufficient to meet the demands of timely logistics. Therefore, several problems persist in the loading and unloading process: firstly, the standardization of pallets is low; secondly, logistics companies prioritize higher loading rates to increase profits; and thirdly, the lack of industry standards for loading and unloading makes the development of automation systems costly and technically challenging. Summary of the Invention

[0003] To address the above problems, this invention proposes a continuous conveying automatic loading and unloading device, the specific technical solution of which is as follows:

[0004] A continuous conveying automatic loading and unloading device includes:

[0005] The loading and unloading mechanism transports goods according to the required stacking position. It includes at least a telescopic beam that can be extended in multiple stages and a front-end working platform. The telescopic beam is equipped with a transport unit for longitudinal horizontal transport of goods. The front-end working platform is equipped with various sensors and can perform vertical and lateral compensation according to the stacking height and width. It can also control the goods to turn according to the stacking rules so as to stack the goods into the transport vehicle.

[0006] A lateral conveying mechanism is used for the horizontal lateral transport of goods and pushes the goods onto the transport units of the loading and unloading mechanism;

[0007] Vertical lifts are used to lift goods vertically and transfer them to a horizontal conveyor.

[0008] A longitudinal conveyor mechanism is used to transport goods horizontally and longitudinally onto a vertical lift; and

[0009] The palletizing / depalletizing mechanism uses a robot to sequentially stack goods on pallets onto a longitudinal conveyor.

[0010] The loading and unloading mechanism and the lateral conveying mechanism are installed on a lifting platform and can move laterally according to the stacking rules, or move up and down synchronously on the lifting platform.

[0011] Furthermore, the lifting platform includes a fixed frame, a lifting frame, and a lifting system. The lifting system is installed on the top of the fixed frame and can drive the lifting frame to move up and down on the fixed frame.

[0012] Furthermore, rollers that contact the fixed frame are respectively provided around the sides of the lifting frame, a support beam is provided on the front side of the lifting frame, a support rail for lateral movement of the lateral conveying mechanism is installed on the support beam, and a pushing mechanism for pushing goods onto the transport unit of the first-stage telescopic beam is provided on the outer side of the support beam.

[0013] Furthermore, both the fixed frame and the vertical lift are mounted on a movable chassis assembly, which is equipped with a transverse sliding main board that can move laterally, and the fixed frame is mounted on the transverse sliding main board.

[0014] Furthermore, the telescopic beam includes a primary telescopic beam and a secondary telescopic beam, both of which have a transport unit inside. The primary telescopic beam is installed inside the lifting frame in a controllable longitudinal movement manner, and the secondary telescopic beam is installed inside the primary telescopic beam in a controllable longitudinal movement manner.

[0015] Furthermore, the front-end operating platform includes a front-end conveying unit, a lifting body, and a rotating mechanism.

The front-end conveying unit is horizontally movable and installed at the front end of the lifting body. The front-end conveying unit is equipped with a roller conveying unit for transporting goods. The rotating mechanism allows the goods to be rotated 90° and installed inside the roller conveying unit.

[0016] Furthermore, the front end of the front-end conveying unit is provided with a drawer plate that can be quickly extended and retracted into it.

[0017] Furthermore, the vertical lift is provided with a series of fixed rods arranged side by side on the circulating lifting mechanism. Each fixed rod is provided with a row of comb teeth that can carry goods. The beginning of the transverse conveying mechanism is provided with a first comb plate through which each comb tooth can pass. The first comb plate is provided with a transplanter that allows goods to be moved from it to the transverse conveying mechanism.

[0018] Furthermore, the end of the longitudinal conveying mechanism is provided with a second comb plate through which each comb tooth can pass, and a baffle is provided on the outer side of the second comb plate.

[0019] Furthermore, the transport unit is one of a belt transport unit, a plate chain transport unit, or a roller transport unit.

[0043] This automatic loading and unloading device is suitable for automated loading and unloading operations of products packaged in general-purpose cartons and bags produced by manufacturing enterprises between transport vehicles (end-opening box trucks and containers) and logistics warehouses. This automatic loading and unloading device has the functions of automatic loading, unloading, transmission and palletizing of products.

[0044] like Figures 1 to 5 As shown, a continuous conveying automatic loading and unloading device includes a loading and unloading mechanism 3, a transverse conveying mechanism 5, a vertical lifting platform 4, a longitudinal conveying mechanism 6, and a stacking / unstacking mechanism 7; wherein:

[0045] The depalletizing mechanism 7 uses a robot to sequentially stack the goods 8 on the pallet onto the longitudinal conveyor mechanism 6. The robot is a conventional depalletizing robot, which is equipped with at least a vision sensor, a laser sensor, or a force sensor to identify the goods 8 and their specific location. It uses computer vision algorithms to grasp the goods 8 and position them on the longitudinal conveyor mechanism 6.

[0046] The longitudinal conveying mechanism 6 is used to receive the goods 8 placed by the robot and transport the goods 8 horizontally and longitudinally to the vertical lift 4.

[0047] The vertical lift 4 is used to receive the goods 8 transported by the longitudinal conveying mechanism 6, and to lift the goods 8 vertically and transfer them to the transverse conveying mechanism 5.

[0048] The lateral conveying mechanism 5 is used to receive the goods 8 transported by the vertical elevator 4, transport the goods 8 horizontally, and push the goods 8 onto the loading and unloading mechanism 3.

[0049] The loading and unloading mechanism 3 transports the goods 8 according to the required stacking position. It includes at least a telescopic beam 31 that can be extended in multiple stages and a front-end working platform 32. The telescopic beam 31 is equipped with a transport unit 313 for longitudinal horizontal transport of the goods 8. The front-end working platform 32 is equipped with various sensors and can perform vertical and lateral compensation according to the stacking height and width. It can also control the goods 8 to turn according to the stacking rules so that the goods 8 can be stacked into the transport vehicle 9.

[0050] Meanwhile, the loading and unloading mechanism 3 and the transverse conveying mechanism 5 are installed on a lifting platform 2 and can move laterally according to the stacking rules, or move up and down synchronously on the lifting platform 2.

[0051] like Figure 1 , 2 As shown, the lifting platform 2 includes a fixed frame 21, a lifting frame 22, and a lifting system 23. The lifting system 23 is installed on the top of the fixed frame 21 and can drive the lifting frame 22 to move up and down on the fixed frame 21.

[0052] In one embodiment, rollers 221 that contact the fixed frame 21 are respectively provided around the sides of the lifting frame 22. A support beam 222 is provided on the front side of the lifting frame 22. A rail 223 for laterally moving the lateral conveying mechanism 5 is installed on the support beam 222. A pushing mechanism 224 for pushing the goods 8 onto the transport unit 313 of the telescopic beam 31 is provided on the outside of the support beam 222.

[0053] like Figure 2As shown, the fixed frame 21 and the vertical lift 4 are both mounted on a movable chassis assembly 1. The chassis assembly 1 is provided with a transverse moving main board 11 that can move laterally, and the fixed frame 21 is mounted on the transverse moving main board 11.

[0054] Specifically, the chassis assembly 1 can be fixed to a designated loading and unloading area by ground foundation, or it can be driven to move by adding a walking device 13, realizing mechanized operation in different loading and unloading areas (changeover points). The chassis assembly 1 is provided with a track 12 for the transverse main board 11 to move laterally, and the chassis assembly 1 is provided with a first drive mechanism that can drive the transverse main body to move on the track 12.

[0055] For example, the chassis assembly 1 is provided with tracked walking mechanisms on both sides, and the chassis assembly 1 has sufficient weight to prevent overturning during the transportation of goods 8.

[0056] Specifically, the bottom end of the fixed frame 21 is mounted on the chassis assembly 1. When the lifting frame 22 moves up and down on the fixed frame 21, the rollers 221 on the lifting frame 22 travel along the outer side of the fixed frame 21, and the frictional resistance between the lifting frame 22 and the fixed frame 21 is reduced by rolling friction.

[0057] In one embodiment, the lifting system 23 includes at least a second drive mechanism 231 and multiple steel wire ropes 232. The drive end of the second drive mechanism 231 can be symmetrically connected to multiple sets of rollers 233 for winding the steel wire ropes 232. The ends of the steel wire ropes 232 are symmetrically suspended from the top surface of the lifting frame 22, so that the second drive mechanism 231 controls the lifting movement of the lifting frame 22 through the steel wire ropes 232.

[0058] The support beam 222 is equipped with a third drive mechanism for controlling the movement of the lateral conveying mechanism 5 on the support rail 223. When the fixed frame 21 moves laterally following the lateral moving main plate 11, the third drive motor can drive the lateral conveying mechanism 5 to move laterally in the opposite direction, thereby ensuring that the relative position of the lateral conveying mechanism 5 and the vertical lift 4 does not change, so that the goods 8 can always be transported from the vertical lift 4 to the lateral conveying mechanism 5. In addition, the pushing mechanism 224 moves with the fixed frame 21 to ensure that the pushing mechanism 224 can always be aligned with the telescopic beam 31 to push the goods 8 onto the transport unit 313.

[0059] For example, the second drive mechanism 231 can be a winch or a regular motor; the push mechanism 224 can be an electric mechanism with telescopic reciprocating motion, such as a hydraulic cylinder or an electric push rod.

[0060] It should be noted that the fixed frame 21 can be configured as a height-adjustable structure, so as to adapt to the loading needs of vehicles 9 of different heights.

[0061] like Figure 1 , 2 As shown, the telescopic beam 31 includes a primary telescopic beam 311 and a secondary telescopic beam 312, both of which are equipped with a transport unit 313 inside. The primary telescopic beam 311 is installed inside the lifting frame 22 in a controllable longitudinal movement manner, and the secondary telescopic beam 312 is installed inside the primary telescopic beam 311 in a controllable longitudinal movement manner.

[0062] Specifically, the primary telescopic beam 311 can be installed inside the lifting frame 22 via the rail 12, and a fourth drive mechanism is provided to control the primary telescopic beam 311 to telescopically move along the rail. The transport unit 313 installed inside the primary telescopic beam 311 extends outwards to its rear end, ensuring that when the primary telescopic beam 311 moves forward longitudinally to its limit position within the lifting frame 22, the goods 8 can always be pushed onto the transport unit 313. The secondary telescopic beam 312 can be installed inside the primary telescopic beam 311 via the rail, and a fifth drive mechanism is provided to control the secondary telescopic beam 312 to telescopically move along the rail, thereby controlling the overall telescopic length of the telescopic beam 31 and achieving positioning movement during the palletizing process.

[0063] It should be noted that the telescopic beam 31 is not limited to first-level and second-level, and the number of levels of the telescopic beam 31 can be increased to meet the length requirements of various vehicles 9.

[0064] like Figure 2 , 5 As shown, the front-end operating platform 32 includes a front-end conveying unit 321, a lifting body 33, and a rotating mechanism 34. The lifting body 33 is vertically movable and installed at the front end of the secondary telescopic beam 312. The front-end conveying unit 321 is horizontally movable and installed at the front end of the lifting body 33. The front-end conveying unit 321 is equipped with a roller conveying unit 322 for transporting goods 8. The rotating mechanism 34 can rotate the goods 8 90° and install them in the roller conveying unit.

[0065] Specifically, the front side of the lifting body 33 is provided with a first slide rail 331 that can be connected to the front-end conveying unit 321. A sixth drive mechanism can control the front-end conveying unit 321 to move laterally along the first slide rail 331, thereby achieving lateral compensation based on the position of the front-end conveying unit 321. The rear side of the lifting body 33 is provided with a second slide rail 332 that can move vertically at the front end of the secondary telescopic beam 312. The second slide rail 332 is embedded in the front end of the secondary telescopic beam 312 to prevent the lifting body 33 from falling off. The front end of the secondary telescopic beam 312 is provided with a seventh drive mechanism that can drive the lifting body 33 to move vertically, thereby achieving longitudinal compensation based on the position of the front-end conveying unit 321. Ultimately, this achieves position compensation or adjustment for the width and height limits of the transport vehicle 9 that the secondary telescopic beam 312 cannot reach.

[0066] In one embodiment, the rotating mechanism 34 is located inside the front end of the telescopic unit and includes at least one lifting drive unit. The lifting drive unit has a lifting plate positioned below the roller transport unit 322, used to lift the goods 8 transported directly above the rotating mechanism 34 upwards and detach them from the roller transport unit 322. The lifting plate employs a cross-shaped mechanism embedded within the roller transport unit 322, thus not affecting the transport of the goods 8 on the roller transport unit 322. The rotating mechanism 34 also includes an eighth drive mechanism for controlling the lifting drive unit to rotate 90°, thereby achieving a 90° rotation of the goods 8. After rotation, the lifting drive unit controls the lifting plate to reset, and the goods 8 fall back onto the roller transport unit 322 to continue rearward transport.

[0067] In one embodiment, the front end of the front-end conveying unit 321 is provided with a retractable plate 35 that can quickly extend and retract into it. The retractable plate 35 is used to support the goods 8 transported by the transport unit 313 within the secondary telescopic beam 312, and to quickly retract the retractable plate 35 into the front-end conveying unit 321, thereby enabling the stacking of the goods 8. The front-end conveying unit 321 is internally provided with a ninth drive mechanism for controlling the retractable movement of the retractable plate 35.

[0068] The front end of the front-end conveying unit 321 is equipped with at least a combination of position sensors, distance sensors, shape sensors, or photoelectric sensors to detect the position of the goods 8 during transportation, identify the position and height of the goods 8 during the palletizing process, and detect whether the palletizing of the goods 8 meets the requirements, so as to ensure that the goods 8 are accurately palletized to the designated position according to the palletizing rules, and also to prevent the palletized goods 8 from collapsing, thereby improving the safety of palletizing.

[0069] like Figure 2 , 3As shown in Figure 4, the vertical lifting machine 4 has multiple fixed rods 43 arranged side by side on the circulating lifting mechanism. Each fixed rod 43 has a row of comb teeth 44 that can carry goods 8. The beginning of the transverse conveying mechanism 5 is provided with a first comb plate 51 through which each comb tooth 44 can pass. The first comb plate 51 is provided with a transplanter 52 that allows the goods 8 to be moved from it to the transverse conveying mechanism 5.

[0070] In one embodiment, the end of the longitudinal conveying mechanism 6 is provided with a second comb plate 61 through which each comb tooth 44 can pass, and a baffle 62 is provided on the outer side of the second comb plate 61.

[0071] The vertical lift 4 is a conventionally used device, which includes at least a housing 41 vertically mounted on the chassis assembly 1 and a lifting and transporting unit 42 that circulates on one side of the housing 41. The fixing rod 43 is mounted on the lifting and transporting unit 42. The second comb plate 61 is mounted near the bottom end of the lifting section of the lifting and transporting unit 42, and the first comb plate 51 is mounted near the high end of the descending section of the lifting and transporting unit 42, thereby lifting the goods 8 transported by the longitudinal transporting unit 313 upward onto the transverse transporting unit 313.

[0072] The second comb plate 61 is level with the longitudinal transport unit 313. Using the kinetic energy of the longitudinal transport unit 313, the goods 8 can be pushed onto the second comb plate 61 and blocked by the baffle 62 to prevent them from falling. After the comb teeth 44 pass through the second comb plate 61, they lift the goods 8 upward, thereby realizing the upward lifting of the goods 8.

[0073] like Figure 4 As shown, the transplanter 52 is installed on the upper surface of the first comb plate 51. When the comb teeth 44 pass through the first comb plate 51, the goods 8 are blocked and remain on the first comb plate 51. Then, the transplanter 52 drives the goods 8 to move onto the transverse conveying mechanism 5.

[0074] For example, the transport units 313 provided in the longitudinal conveying mechanism 6 and the transverse conveying mechanism 5 can be belt transport units 313, plate chain transport units 313 or roller transport units 322, etc.; the transport units 313 in the primary telescopic beam 311 and the secondary telescopic beam 312 can be belt transport units 313, etc.

[0075] For example, the palletizing rule may be a "five-petaled" pallet for bags or a slotted pallet for boxes.

[0076] It should be noted that this automatic loading and unloading device is also equipped with a loading software system for controlling the transportation and palletizing of goods 8. This loading software system is programmed by a PLC controller. Based on the palletizing rules, sensor signals, and corresponding algorithms, it controls the first drive mechanism, the second drive mechanism 231, the third drive mechanism, the fourth drive mechanism, the fifth drive mechanism, the sixth drive mechanism, the seventh drive mechanism, the eighth drive mechanism, the ninth drive mechanism, the transverse conveying mechanism 5, the longitudinal conveying mechanism 6, the lifting and transporting unit 42, the lifting drive unit, and the transporting unit 313 within the first-level telescopic beam 311 and the second-level telescopic beam 312, so as to realize the transportation of goods 8 and the palletizing according to the palletizing rules.

[0077] Workflow example using a bagged packaging scenario:

[0078] (1) Before starting the operation, the extraction plate 35 retracts into the front conveying unit 321, the secondary telescopic beam 312 retracts into the primary telescopic beam 311, and the primary telescopic beam 311 moves to the rear end "0" position of the lifting frame 22; the transport vehicle 9 (truck) opens the end door and drives to the designated loading and unloading area; input the parameters of the transport vehicle 9 and the loading specifications in the loading software, and the system automatically generates the loading plan.

[0079] (2) The first-level telescopic beam 311, the second-level telescopic beam 312 and the extraction plate 35 are all controlled to move automatically through the drive mechanism according to the system preset logic and reach the designated position.

[0080] (3) Palletized goods 8 are transported to the designated destacking and stacking position by forklift. The destacking and stacking machine continuously and orderly places goods 8 into the longitudinal conveying mechanism 6 according to the stacking direction. The vertical lift 4 continuously transfers and lifts goods 8. The transfer machine 52 transfers goods 8 to the transverse conveying mechanism 5. The pushing mechanism 224 pushes goods 8 into the transport unit 313 in the first-level telescopic beam 311. The transport unit 313 continuously transports goods 8 to the front-end operating platform 32.

[0081] (4) When the front-end operation platform 32 receives the goods 8 transported by the transport unit 313, it quickly moves automatically to the logical position on the lifting body 33. The rotating mechanism 34 controls the rotation of the goods 8 according to the stacking rules, and the extraction plate 35 quickly retracts to stack the goods 8 in the designated position. When the final layer of goods 8 needs to be stacked close to the top of the transport vehicle 9, the height difference between the secondary telescopic arm and the front-end operation platform 32 can be eliminated by the automatic lifting of the lifting body 33, achieving a 100% loading rate of the internal space of the transport vehicle 9. By analogy, after stacking the goods 8 on one wall, the secondary telescopic beam 312 moves back the longitudinal distance of one wall and continues to stack goods according to the stacking rules. Among them, the primary telescopic beam 311 of the above operations does not move.

[0082] (5) When the secondary telescopic beam 312 is fully retracted, the primary telescopic beam 311 retracts back to the "0" position, and the secondary telescopic beam 312 extends to continue stacking. The above process is repeated to stack the entire space of the vehicle 9.

[0083] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
