Description

Technical Field

[0001] This invention relates to the field of baggage transfer and palletizing technology, and more specifically, to a baggage alignment and conveying system and a baggage alignment and conveying method. Background Technology

[0002] In existing automated baggage transfer systems, baggage is typically transported from the sorting area to the picking platform via a conveyor line, and then stacked by robots.

[0003] However, existing technologies generally use a single conveyor line for direct transport, lacking effective control over the luggage's posture and a precise pushing mechanism. When luggage is transported from the upper conveyor line to the picking platform, due to offsets, inertial slippage, or instability in the center of gravity during transport, luggage often exhibits non-standard postures such as horizontal offset, tilting, or disordered orientation. This causes subsequent robots to be unable to accurately identify and grasp the luggage, leading to jamming, falling, or palletizing failure. At the same time, existing luggage transport systems lack effective blocking, positioning, and pushing coordination mechanisms, making it impossible to reliably stop luggage at precise locations and push it stably to the designated position. Improper pushing force or timing often causes luggage to deviate from its position or be pushed repeatedly, affecting the system's operating efficiency.

[0004] In addition, most existing baggage handling platforms are fixed platforms, which cannot adjust the direction or compensate the height of the baggage, further limiting the robot's adaptability to operation in multi-dimensional space and making it difficult to meet the needs of high-concurrency and high-precision automated transfer scenarios.

[0005] Therefore, existing baggage handling systems lack posture correction and precise push devices for baggage, resulting in non-standardized posture, inaccurate push positioning, and low success rate and efficiency of subsequent grabbing during the transfer process. This seriously affects the overall efficiency and reliability of baggage transfer, especially in high-traffic hub scenarios such as airports and high-speed rail stations, where the frequency of manual intervention increases and the degree of automation is difficult to improve. This system cannot meet the urgent needs of modern intelligent logistics for efficient, stable, and unmanned operations and urgently needs to be solved. Summary of the Invention

[0006] This invention provides a baggage orientation correction and conveying system and a baggage orientation correction and conveying method, which at least solves the problems of the lack of baggage orientation correction and precise push device in the existing baggage conveying system, resulting in non-standardized posture, inaccurate push positioning and low success rate and efficiency of subsequent grabbing of baggage during the transfer process.

[0007] To address the aforementioned problems, according to one aspect of the present invention, a baggage alignment and conveying system is provided, comprising: a carrying component, a conveying component, a discharging component, a platform component, and a centering constraint component; having a first direction and a second direction perpendicular to each other in a horizontal plane; the conveying component is disposed on the carrying component for transporting baggage to be transferred along or away from the first direction; the platform component is disposed on the carrying component and located on one side of the conveying component along the second direction; the centering constraint component is movably disposed on the carrying component; the discharging component is movably disposed on the carrying component; wherein, the centering constraint component has a constraint cavity inside for correcting the baggage to be transferred, the discharging component is movable along or away from the second direction, and the discharging component is used to push the baggage to be transferred on the conveying component to detach from the conveying component and push the baggage to be transferred to the platform component; the platform component is vertically adjustable and rotatable to adjust the position and orientation of the baggage to be transferred located on the platform component; the centering constraint component is used to adjust the baggage to be transferred to a designated position on the platform component; the dimension of the constraint cavity along the first direction is adjustable to adapt to the external dimensions of the baggage to be transferred.

[0008] Furthermore, the position of the centering constraint component relative to the platform component is adjustable; when it is necessary to adjust the position of the luggage to be transferred on the platform component, the inner wall of the constraint cavity abuts against the outside of the luggage to be transferred, and by moving the centering constraint component, the luggage to be transferred is moved to the designated position on the platform component; and / or, the extension direction of the constraint cavity is parallel to the second direction; the discharge component pushes the luggage to be transferred through the constraint cavity to the platform component; the inner wall of the constraint cavity cooperates with the luggage to be transferred to adjust the posture of the luggage to be transferred and constrain the luggage to be transferred to move to the designated position along the second direction.

[0009] Furthermore, the centering constraint assembly includes a first adjusting plate, a second adjusting plate, a first movable frame, and a second movable frame; the bearing assembly includes a first transmission screw; the first adjusting plate is disposed on the first movable frame to follow the movement of the first movable frame; the second adjusting plate is disposed on the second movable frame to follow the movement of the second movable frame; the first movable frame is movably disposed on the bearing assembly along a first direction or away from the first direction, and the second movable frame is movably disposed on the bearing assembly along the first direction or away from the first direction; the first movable frame and the second movable frame are respectively threadedly driven into the first transmission screw, and the central axis of the first transmission screw is parallel to the first direction; wherein, the first adjusting plate and the second adjusting plate are spaced apart on both sides of the platform assembly along the first direction to form a constraint cavity; by rotating the first transmission screw, the first movable frame and the second movable frame are driven to move to adjust the size of the constraint cavity along the first direction.

[0010] Furthermore, the designated position is located in the middle of the top of the platform assembly. When it is necessary to adjust the position of the luggage to be transferred on the platform assembly, the first or second adjusting plate abuts against the outside of the luggage to be transferred against the outer wall of the constraint cavity to push the luggage to be transferred to the designated position. When the luggage to be transferred moves to the designated position, the first and second adjusting plates simultaneously clamp the two ends of the luggage to be transferred along the first direction; and / or, the first and second adjusting plates extend along the second direction respectively. When the discharge assembly pushes the luggage to be transferred through the constraint cavity, the first and second adjusting plates respectively engage with the contact sensors at the two ends of the luggage to be transferred along the first direction to limit the movement of the luggage to be transferred, thereby adjusting the posture of the luggage to be transferred and constraining the luggage to be transferred to move along the constraint cavity to the designated position.

[0012] Furthermore, the baggage alignment and conveying system also includes a blocking component, which includes a blocking plate, a photoelectric sensor, and a blocking drive unit. The blocking plate is movably mounted above the conveying component. The blocking drive unit is mounted on the carrying component and is drivenly connected to the blocking plate to drive the blocking plate to rise and fall. The photoelectric sensor is electrically connected to the blocking drive unit and is used to detect the baggage to be transferred on the conveying component. When the photoelectric sensor detects the baggage to be transferred, the blocking drive unit drives the blocking plate to descend, fixing the baggage to be transferred along the first direction by blocking it. The discharge component pushes the baggage to be transferred away from the conveying component and moves the baggage to be transferred onto the platform component.

[0013] Furthermore, the blocking drive unit includes a drive motor, a transmission gear, and a transmission rack. The drive motor is connected to the transmission gear to drive the transmission gear to rotate. The transmission rack is vertically arranged and fixedly connected to the blocking plate.

[0015] Furthermore, the platform component includes a material-picking platform, a rotation drive unit, and a lifting drive unit; the lifting drive unit is driven to connect with the rotation drive unit to drive the rotation drive unit to move up and down; the material-picking platform is mounted on the rotation drive unit, which drives the material-picking platform to rotate around a vertical axis; by rotating and lifting the material-picking platform, the position and orientation of the luggage to be transferred on the material-picking platform are adjusted; the material-picking platform is used to cooperate with an external robot so that the external robot can grasp and stack the luggage to be transferred; and / or, the luggage orientation-correcting conveying system also includes a control terminal, which is electrically connected to the conveying component, the discharging component, the platform component, and the centering constraint component respectively, to control the conveying component, the discharging component, the platform component, and the centering constraint component to work together; and / or, one discharging component, platform component, and centering constraint component that cooperates with each other constitutes a cooperation group, and there are multiple cooperation groups, which are spaced apart above the conveying component along a first direction.

[0016] According to another aspect of the present invention, a baggage alignment and conveying method is provided, which is applied to the baggage alignment and conveying system described above. The baggage alignment and conveying method includes the following steps: controlling a conveying component to transport baggage to be transferred along a first direction; controlling a discharging component to push the baggage to be transferred on the conveying component to detach from the conveying component according to a recognition timing, and pushing the baggage to be transferred to move onto a platform component; controlling a centering constraint component to adjust the baggage to be transferred to a designated position on the platform component; controlling the platform component to lift and / or rotate to adjust the position and orientation of the baggage to be transferred located on the platform component; and controlling the platform component to cooperate with an external robot so that the external robot can grasp and stack the baggage to be transferred.

[0017] The present invention provides a baggage alignment and conveying system, comprising: a carrying component, a conveying component, a discharging component, a platform component, and a centering constraint component; having a first direction and a second direction perpendicular to each other in a horizontal plane; the conveying component is disposed on the carrying component for transporting baggage to be transferred along or away from the first direction; the platform component is disposed on the carrying component and located on one side of the conveying component along the second direction; the centering constraint component is movably disposed on the carrying component; the discharging component is movably disposed on the carrying component; wherein, the centering constraint component has a constraint cavity inside for correcting the baggage to be transferred, the discharging component can move along or away from the second direction, and the discharging component is used to push the baggage to be transferred on the conveying component to detach from the conveying component and push the baggage to be transferred to the platform component; the platform component can be raised, lowered, and rotated to adjust the position and orientation of the baggage to be transferred located on the platform component; the centering constraint component is used to adjust the baggage to be transferred to a designated position on the platform component; the size of the constraint cavity along the first direction is adjustable to adapt to the external size of the baggage to be transferred.

[0018] This invention utilizes a simple structure to achieve directional transport and posture adjustment of baggage awaiting transfer by setting up a conveying component, an unloading component, a platform component, and a centering constraint component to work together. The platform component and centering constraint component eliminate lateral deviations caused by the conveying component or the unloading component pushing the baggage, efficiently correcting the placement orientation of the baggage and ensuring a standardized posture.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figures 1 to 3As shown, an embodiment of the present invention provides a baggage alignment and conveying system, including: a carrying component 10, a conveying component 20, a discharging component 30, a platform component 40, and a centering constraint component 50; having a first direction and a second direction perpendicular to each other in a horizontal plane; the conveying component 20 is disposed on the carrying component 10 for transporting baggage to be transferred along or away from the first direction; the platform component 40 is disposed on the carrying component 10 and located on one side of the conveying component 20 along the second direction; the centering constraint component 50 is movably disposed on the carrying component 10; the discharging component 30 is movably disposed on the carrying component 10; wherein... The centering constraint component 50 has a constraint cavity 51 inside for correcting the luggage to be transferred. The discharge component 30 can move along the second direction or away from the second direction. The discharge component 30 is used to push the luggage to be transferred on the conveying component 20 to detach from the conveying component 20 and push the luggage to be transferred to the platform component 40. The platform component 40 can be raised, lowered and rotated to adjust the position and orientation of the luggage to be transferred on the platform component 40. The centering constraint component 50 is used to adjust the luggage to be transferred to the designated position on the platform component 40. The size of the constraint cavity 51 along the first direction is adjustable to adapt to the external size of the luggage to be transferred.

[0032] This invention, through the coordinated operation of a conveying component 20, a discharging component 30, a platform component 40, and a centering constraint component 50, achieves directional transport and posture adjustment of luggage to be transferred using a simple structure. By incorporating the platform component 40 and the centering constraint component 50, the lateral shift of the luggage to be transferred caused by the conveying component 20 or the pushing process of the discharging component 30 is eliminated, efficiently correcting the placement orientation of the luggage and ensuring a standardized posture. This ultimately facilitates precise handling and stable stacking of luggage by an external robot. This invention achieves luggage posture correction and stable transfer; further integration with an intelligent luggage positioning and screening mechanism can... This invention effectively stabilizes the posture of luggage, intercepts anomalies, and precisely guides its flow, reducing the frequency of delays and system malfunctions in luggage transfer and ensuring stable and efficient luggage transportation throughout the entire process. The invention features a simple and low-cost structure, facilitating assembly and subsequent maintenance. It addresses the shortcomings of existing luggage conveying systems, which lack posture correction and precise pushing devices, leading to non-standardized postures, inaccurate pushing and positioning, and low success rates and efficiency in subsequent grabbing. Practical application has shown that this invention significantly improves the automation level and operational reliability of luggage sorting systems, making it suitable for large-scale deployment.

[0033] like Figure 1 and Figure 2As shown, the position of the centering constraint component 50 relative to the platform component 40 is adjustable; when it is necessary to adjust the position of the luggage to be transferred on the platform component 40, the inner wall of the constraint cavity 51 abuts against the outside of the luggage to be transferred, and by moving the centering constraint component 50, the luggage to be transferred is moved to the designated position on the platform component 40; and / or, the extension direction of the constraint cavity 51 is parallel to the second direction; the discharge component 30 pushes the luggage to be transferred through the constraint cavity 51 to move onto the platform component 40; the inner wall of the constraint cavity 51 cooperates with the limit of the luggage to be transferred to trigger the contact sensor on the top of the inner wall of the constraint cavity 51 to make the luggage reach the centering position, so as to adjust the posture of the luggage to be transferred and constrain the luggage to be transferred to move along the second direction to the designated position.

[0034] The centering constraint component 50 is adjustable relative to the platform component 40, allowing the constraint cavity 51 to dynamically adjust its lateral or longitudinal position relative to the platform component 40 according to the size and target position of the luggage when it is pushed along the second direction by the discharge component 30, thereby achieving centering operations for luggage of different sizes. The extension direction of the constraint cavity 51 is parallel to the second direction, ensuring that the luggage to be transferred passes through the constraint cavity 51 along this direction during the push of the discharge component 30, forming a directional movement path. The inner wall of the constraint cavity 51 is matched with the outer surface of the luggage to be transferred, constraining its posture at multiple points during the passage of the luggage, suppressing its deflection and tilting in the first direction, and forcing it to slide stably along the second direction until it reaches the designated position on the platform component 40. This structural combination effectively solves the problem of posture disorder and positioning deviation of luggage during the transfer process due to the lack of directional constraints, ensuring that the luggage lands on the platform component 40 with a standardized posture and precise position, providing a reliable foundation for subsequent grasping and transfer.

[0035] like Figure 1 and Figure 2As shown, the centering constraint assembly 50 includes a first adjusting plate 52, a second adjusting plate 53, a first moving frame 54, and a second moving frame 55; the bearing assembly 10 includes a first transmission screw; the first adjusting plate 52 is disposed on the first moving frame 54 to follow the movement of the first moving frame 54; the second adjusting plate 53 is disposed on the second moving frame 55 to follow the movement of the second moving frame 55; the first moving frame 54 is movably disposed on the bearing assembly 10 along a first direction or away from the first direction, and the second moving frame 55 is movably disposed on the bearing assembly 10 along the first direction or away from the first direction; the first moving frame 54 and the second moving frame 55 are respectively threadedly driven into the first transmission screw (or driven by a bidirectional synchronous belt), and the central axis of the first transmission screw is parallel to the first direction; wherein, the first adjusting plate 52 and the second adjusting plate 53 are spaced apart on both sides of the platform assembly 40 along the first direction to form a constraint cavity 51; by rotating the first transmission screw or the bidirectional synchronous belt, the first moving frame 54 and the second moving frame 55 are driven to move to adjust the size of the constraint cavity 51 along the first direction.

[0036] The first adjusting plate 52 is fixedly installed on the first movable frame 54 and moves synchronously with the first movable frame 54 along the first direction. The second adjusting plate 53 is fixedly installed on the second movable frame 55 and moves synchronously with the second movable frame 55 along the first direction. The first movable frame 54 and the second movable frame 55 are respectively engaged with the first transmission screw or the bidirectional synchronous belt. When the first transmission screw or the bidirectional synchronous belt rotates, its first transmission screw or synchronous pulley and synchronous belt structure drives the first movable frame 54 and the second movable frame 55 to move in opposite directions, thereby causing the first adjusting plate 52 and the second adjusting plate 53 to move closer or further away synchronously, dynamically adjusting the distance between them. The width of the constraint cavity 51 along the first direction allows it to precisely adapt to luggage of different sizes to be transferred, ensuring that the luggage is stably centered before entering the platform component 40, avoiding offset or jamming due to size mismatch, and improving the stability and efficiency of posture correction. The constraint cavity 51 is set on both sides of the platform component 40 along the first direction, so that the sides of the luggage are always limited and guided by the first adjustment plate 52 and the second adjustment plate 53 during the process of being pushed by the discharge component 30, realizing precise position constraint, providing a stable basic positioning for the subsequent lifting and rotation adjustment of the platform component 40, and significantly improving the success rate and efficiency of subsequent gripping operations.

[0037] It should be noted that, in a specific embodiment of the present invention, the first moving frame 54 and the second moving frame 55 are designed with opposite transmission threads or synchronous belts, so that the first moving frame 54 and the second moving frame 55 can move toward each other or away from each other when the first transmission screw or synchronous belt rotates.

[0038] like Figure 1 and Figure 2As shown, the designated position is located in the middle of the top of the platform assembly 40. When it is necessary to adjust the position of the luggage to be transferred on the platform assembly 40, the first adjusting plate 52 or the second adjusting plate 53 abuts against the outside of the luggage to be transferred towards the outer wall of the constraint cavity 51 to push the luggage to be transferred to the designated position. When the luggage to be transferred moves to the designated position, the first adjusting plate 52 and the second adjusting plate 53 simultaneously clamp the two ends of the luggage to be transferred along the first direction; and / or, the first adjusting plate 52 and the second adjusting plate 53 extend along the second direction respectively. When the discharge assembly 30 pushes the luggage to be transferred through the constraint cavity 51, the first adjusting plate 52 and the second adjusting plate 53 respectively engage with the two ends of the luggage to be transferred along the first direction (e.g., contact sensors at both ends) towards the outer wall of the constraint cavity 51 to adjust the posture of the luggage to be transferred and constrain the luggage to be transferred to move along the constraint cavity 51 to the designated position.

[0039] The designated position is located at the center of the top of the platform component 40. When the discharge component 30 pushes the luggage to be transferred through the constraint cavity 51 along the second direction, the outer walls of the first adjusting plate 52 and the second adjusting plate 53 extending along the second direction and the two ends of the luggage to be transferred along the first direction simultaneously form a limiting fit. Through this structural design, the luggage to be transferred is subject to bidirectional constraint along the first direction during the pushing process, and its posture is corrected to be parallel to the second direction and centered, ensuring that it is positioned at the designated position when it moves to the top of the platform component 40. When the luggage to be transferred arrives at the designated position, the first adjusting plate 52 and the second adjusting plate 53 simultaneously clamp its two ends along the first direction, completing the centering lock and avoiding positional deviation caused by offset or rotation during the pushing process. At the same time, the dimension of the constraint cavity 51 along the first direction can be adjusted by the first transmission screw driving the first moving frame 54 and the second moving frame 55 to move synchronously in opposite directions to adapt to luggage of different sizes and achieve adaptive centering, thereby solving the problems of non-standardized posture and inaccurate positioning, and improving the reliability and efficiency of subsequent gripping operations.

[0040] like Figure 1 and Figure 2 As shown, the bearing assembly 10 also includes a bearing frame 11, on which the first transmission screw is rotatably mounted; the bearing assembly 10 also includes a first sliding guide rail 12, which is fixedly mounted on the bearing frame 11; the extending direction of the first sliding guide rail 12 is parallel to the first direction; the first movable frame 54 and the second movable frame 55 are respectively slidably mounted on the first sliding guide rail 12 and respectively limit the engagement with the first sliding guide rail 12.

[0041] The support frame 11 serves as the mounting base for the centering constraint assembly 50, providing a stable and reliable support structure for the first transmission screw and the first sliding guide rail 12. The first transmission screw is rotatably mounted on the support frame 11 to ensure its rotational accuracy and transmission stability. The first sliding guide rail 12 is fixedly mounted on the support frame 11 and extends in a direction parallel to the first direction, providing a straight guide path for the first moving frame 54 and the second moving frame 55. The first moving frame 54 and the second moving frame 55 are respectively limited and engaged with the first sliding guide rail 12, effectively suppressing their movement along the first direction. Lateral offset or swaying may occur during the movement. At the same time, the first moving frame 54 and the second moving frame 55 are linked to the first transmission screw or synchronous belt through threaded connection, so that the first adjusting plate 52 and the second adjusting plate 53 can move synchronously and equidistantly under the drive of the transmission screw or bidirectional synchronous belt. This controls the width of the constraint cavity 51 along the first direction, ensuring that the inner wall of the constraint cavity 51 always maintains stable and limited contact with the side wall of the luggage to be transferred. This improves the repeatability and positioning consistency of the luggage posture correction and solves the problem of correction failure caused by structural loosening or lack of guidance.

[0042] like Figure 1 As shown, the baggage alignment and conveying system also includes a blocking component 60, which includes a blocking plate, a photoelectric sensor, and a blocking drive unit. The blocking plate is movably mounted above the conveying component 20. The blocking drive unit is mounted on the carrying component 10 and is drivenly connected to the blocking plate to drive the blocking plate to rise and fall. The photoelectric sensor is electrically connected to the blocking drive unit and is used to detect the baggage to be transferred on the conveying component 20. When the photoelectric sensor detects the baggage to be transferred, the blocking drive unit drives the blocking plate to descend, fixing the baggage to be transferred along the first direction by blocking it. The discharge component 30 pushes the baggage to be transferred away from the conveying component 20 and moves the baggage to be transferred onto the platform component 40.

[0043] When the photoelectric sensor detects the luggage to be transferred on the conveying assembly 20, its output signal triggers the blocking drive unit to operate, driving the blocking plate to descend above the conveying assembly 20. This creates a limit on the luggage to be transferred in the first direction, preventing it from continuing to slide or shift due to inertia, and ensuring that the luggage to be transferred is in a stable and stationary state before being pushed by the discharging assembly 30. This fixing effect reduces the positioning deviation caused by position drift during the pushing process, enabling the discharging assembly 30 to push the luggage to be transferred away from the conveying assembly 20 in the second direction and smoothly transfer it to the platform assembly 40. This creates stable and accurate initial conditions for the subsequent centering constraint assembly 50 to perform attitude correction through the adjustable-size constraint cavity 51. At the same time, the lifting and lowering cooperation between the blocking plate and the conveying assembly 20 achieves non-contact interception, reducing the risk of damage to the luggage surface and improving the reliability and applicability of the system.

[0044] like Figure 1 As shown, the blocking drive unit includes a drive motor, a transmission gear, and a transmission rack. The drive motor is connected to the transmission gear to drive the transmission gear to rotate. The transmission rack is vertically arranged and fixedly connected to the blocking plate. The transmission gear meshes with the transmission rack to drive the blocking plate to rise and fall. The photoelectric sensor detects the luggage to be transferred, so that the blocking drive unit can determine whether to drive the blocking plate to block the luggage to be transferred.

[0045] The baffle plate is controlled to rise and fall by a baffle drive unit, which includes a drive motor, a transmission gear, and a transmission rack. The drive motor is connected to the transmission gear to drive its rotation, and the transmission rack is vertically set and fixedly connected to the baffle plate. The transmission gear and the transmission rack mesh with each other, thereby converting the rotational motion of the drive motor into the linear lifting and lowering motion of the baffle plate in the vertical direction, ensuring that the baffle plate has a rapid response, accurate positioning, and smooth operation. When the photoelectric sensor detects the luggage to be transferred on the conveying assembly 20 and identifies its size, position, or motion status information, if the preset interception conditions are met, the photoelectric sensor immediately sends a trigger signal to the baffle drive unit. The drive motor then starts, and the meshing transmission gear and transmission rack lower the baffle plate to a preset height, blocking the luggage to be transferred and stabilizing its position in the first direction, preventing displacement during the pushing process. This provides a reliable positioning reference for the subsequent unloading assembly 30 to push the luggage away from the conveying assembly 20 and transfer it to the platform assembly 40, improving the automation accuracy and operating efficiency of the overall system.

[0046] like Figure 1 As shown, the discharge assembly 30 includes a discharge push plate and a discharge moving frame; the discharge push plate discharges onto the discharge moving frame to follow its movement; the carrying assembly 10 includes a second transmission screw, the central axis of which is parallel to a second direction; the discharge moving frame is threadedly engaged with the second transmission screw, and by rotating the second transmission screw, the discharge moving frame is driven to move, so that the discharge push plate pushes the luggage to be transferred; the carrying assembly 10 also includes a carrying frame body 11, on which the second transmission screw is rotatably mounted; the carrying assembly 10 also includes a second sliding guide rail, which is fixedly mounted on the carrying frame body 11; the extending direction of the second sliding guide rail is parallel to the second direction; the discharge moving frame is slidably mounted on the second sliding guide rail and is limited by the second sliding guide rail.

[0047] The discharge pusher is mounted on the discharge moving frame and moves synchronously with it. The discharge moving frame is threadedly engaged with the second transmission screw. The central axis of the second transmission screw is parallel to the second direction and is rotatably mounted on the support frame 11. When the second transmission screw rotates, it drives the discharge moving frame to make linear displacement along the second direction. At the same time, the discharge moving frame is slidably engaged with and limited by the second sliding guide rail fixed on the support frame 11, ensuring that the movement trajectory extends along the second direction and avoiding deviation or jamming caused by structural loosening or lateral force during the pushing process. This structural combination enables the discharge pusher to achieve stable and low-vibration pushing action when pushing the luggage to be transferred out of the conveying component 20 and transferred to the platform component 40, improving the positioning accuracy and action reliability of the luggage pushing, and providing a stable initial position for the subsequent lifting and rotation of the platform component 40.

[0048] like Figure 1 and Figure 3 As shown, the platform component 40 includes a material-picking platform 41, a rotation drive unit 42, and a lifting drive unit 43. The lifting drive unit 43 is driven to connect with the rotation drive unit 42 to drive the rotation drive unit 42 to move up and down. The material-picking platform 41 is mounted on the rotation drive unit 42, which drives the material-picking platform 41 to rotate around a vertical axis. By rotating and lifting the material-picking platform 41, the position and orientation of the luggage to be transferred on the material-picking platform 41 can be adjusted. The material-picking platform 41 is used to cooperate with an external robot so that the external robot can grasp and... The system stacks luggage awaiting transfer; and / or, the luggage alignment and conveying system also includes a control terminal, which is electrically connected to the conveying component 20, the discharging component 30, the platform component 40, and the centering constraint component 50 respectively, to control the conveying component 20, the discharging component 30, the platform component 40, and the centering constraint component 50 to work together; and / or, a corresponding discharging component 30, platform component 40, and centering constraint component 50 constitute a cooperation group, and there are multiple cooperation groups, which are spaced apart above the conveying component 20 along the first direction.

[0049] Platform component 40 includes a picking platform 41, a rotation drive unit 42, and a lifting drive unit 43. The lifting drive unit 43 is driven by the rotation drive unit 42, enabling the rotation drive unit 42 to move vertically, thereby allowing the picking platform 41 mounted on the rotation drive unit 42 to adjust its height. Simultaneously, the rotation drive unit 42 can drive the picking platform 41 to rotate around a vertical axis, adjusting the posture and orientation of the luggage placed on the picking platform 41 to meet the requirements of external robot grasping and stacking. Through multi-dimensional posture adjustment, the picking platform 41 ensures that the luggage has a uniform and stable standard posture during handover, improving the success rate and efficiency of external robot grasping. Furthermore, the luggage posture-correcting and conveying mechanism... The system is equipped with multiple coordination groups, each consisting of a discharge component 30, a platform component 40, and a centering constraint component 50. These coordination groups are arranged at intervals above the conveying component 20 along the first direction, allowing multiple bags to be pushed, centered, and corrected in attitude simultaneously, achieving parallel processing. The control terminal is electrically connected to the conveying component 20, discharge component 30, platform component 40, and centering constraint component 50, enabling unified coordination of the action sequence of each component. This ensures that each coordination group synchronously performs pushing, constraint, lifting, and rotation operations after the baggage arrives at the designated position, thereby achieving efficient collaborative operation of multiple workstations and comprehensively improving the system's concurrent processing capability for multiple batches of baggage and the controllability of the overall operating rhythm.

[0050] The present invention also provides a baggage alignment and conveying method, which is applied to the baggage alignment and conveying system described above. The baggage alignment and conveying method includes the following steps: controlling the conveying component 20 to transport the baggage to be transferred along a first direction; controlling the discharging component 30 to push the baggage to be transferred on the conveying component 20 to detach from the conveying component 20 according to the recognition timing, and pushing the baggage to be transferred to the platform component 40; controlling the centering constraint component 50 to adjust the baggage to be transferred to a designated position on the platform component 40; controlling the platform component 40 to lift up and down and / or rotate to adjust the position and orientation of the baggage to be transferred on the platform component 40; and controlling the platform component 40 to cooperate with an external robot to facilitate the external robot to grab and stack the baggage to be transferred.

[0051] By controlling the conveying component 20 to transport the luggage to be transferred along the first direction, and combining this with the unloading component 30 pushing the luggage away from the conveying component 20 and accurately transferring it to the platform component 40 along the second direction at the recognition time, a smooth transition of the luggage from linear conveying to planar receiving is ensured. Subsequently, the centering constraint component 50 uses the adjustable-size constraint cavity 51 to center and correct the position of the luggage in the first direction, reducing the offset generated during the pushing process and improving the consistency of posture. The platform component 40 simultaneously executes lifting and rotating actions to realize multi-dimensional posture adjustment of the luggage in the height and circumferential directions, so that it is finally in a standard state that meets the requirements of external robot grasping and stacking. This method coordinates the action logic of each component, effectively reducing the risk of luggage jamming, misalignment or secondary adjustment caused by abnormal posture during the transfer process, and improving the overall transfer efficiency and operational reliability of the system.

[0052] The working process and principle of a specific embodiment of the present invention will now be described in detail as follows:

[0053] The control conveying assembly 20 transports the luggage to be transferred along the first direction. When the photoelectric sensor detects the luggage to be transferred, the blocking drive unit drives the blocking plate to descend, fixing the luggage to be transferred along the first direction by blocking it. Subsequently, the discharge push plate of the discharge assembly 30 moves along the second direction under the drive of the discharge moving frame, pushing the luggage to be transferred, which is fixed by the blocking plate, to detach from the conveying assembly 20 and pushing the luggage to be transferred onto the platform assembly 40. During the process of pushing the luggage to be transferred, its two ends along the first direction are limited and cooperate with the inner walls of the first adjusting plate 52 and the second adjusting plate 53 of the centering constraint assembly 50. The size of the constraint cavity 51 along the first direction is adjusted by the rotation of the first transmission screw, which drives the first moving frame 54 and the second moving frame 55 to move in opposite directions or in opposite directions along the first direction, so that the first adjusting plate 52 and the second adjusting plate 53 simultaneously clamp the luggage to be transferred along the first direction. The platform component 40 is aligned with the designated position of the luggage to be transferred. After the luggage is aligned, the lifting drive 43 of the platform component 40 drives the rotation drive 42 to move up and down in the vertical direction. At the same time, the rotation drive 42 drives the picking platform 41 to rotate around the vertical axis to adjust the position and orientation of the luggage to be transferred on the picking platform 41, so that the luggage to be transferred is in a standard posture that meets the requirements of external robot grasping and stacking. The control terminal is electrically connected to the conveying component 20, the discharging component 30, the platform component 40 and the centering constraint component 50 respectively to coordinate the collaborative work of each component. In addition, multiple cooperation groups composed of the conveying component 20, the discharging component 30, the platform component 40 and the centering constraint component 50 are set at intervals along the first direction. The discharging component 30, the platform component 40 and the centering constraint component 50 of each cooperation group operate independently to realize the parallel processing of multiple batches of luggage to be transferred.

[0054] In summary, this invention provides a baggage orientation correction and conveying system and method. By configuring a conveying component 20, an unloading component 30, a platform component 40, and a centering constraint component 50 to work together, this invention achieves directional transport and attitude adjustment of baggage to be transferred using a simple structure. By using the platform component 40 and the centering constraint component 50, the lateral deviation caused by the conveying component 20 or the unloading component 30 pushing the baggage to be transferred can be eliminated, effectively correcting the placement direction of the baggage and ensuring that the baggage has a standardized posture. This ultimately facilitates precise picking up and stable stacking of baggage by an external robot. This invention achieves baggage posture correction and stable transfer, and subsequent... Combined with an intelligent baggage positioning and screening mechanism, this invention can effectively stabilize baggage posture, intercept anomalies, and accurately guide baggage, reducing the frequency of baggage transfer delays and system error rates, and ensuring stable and efficient baggage transportation throughout the entire process. The invention is simple in structure and low in cost, easy to assemble and maintain, and solves the problems of existing baggage conveying systems lacking posture correction and precise pushing devices, resulting in non-standardized posture, inaccurate pushing and positioning, and low success rate and efficiency of subsequent grabbing during baggage transfer. In practical applications, this invention has significantly improved the automation level and operational reliability of baggage sorting systems, making it suitable for large-scale deployment.
