[0002] Currently, airport baggage handling typically employs an automated system combining baggage conveyors and transfer robots to complete baggage loading and sorting. Visual recognition devices on the baggage conveyor read baggage information; once it matches preset information, the robot uses its end effector to pick up the baggage, transfer it to palletizing racks, and follow a workflow of picking, transferring, and resetting.

[0003] However, in the existing solution, after the robot resets, the next piece of luggage to be processed continues to move along the conveyor line, and its position is not fixed. The transfer robot needs to travel between different locations, affecting the overall efficiency of luggage transfer. Utility Model Content

[0004] This invention provides a conveying device and a baggage retrieval system having the same, to solve the problem of low baggage transfer efficiency in the prior art.

[0005] According to one aspect of the present invention, a conveying device is provided, comprising: a support plate disposed above a baggage conveyor belt, wherein the extension direction of the support plate is perpendicular to the conveying direction of the baggage conveyor belt, the baggage conveyor belt is inclined in the width direction, and the support plate is parallel to the baggage conveyor belt; a push plate movably disposed on the support plate, the push plate being capable of reciprocating along the height direction and reciprocating along the extension direction of the support plate; a stop structure disposed on the push plate, the stop structure having a flipping part having a stop position and a clearance position relative to the push plate, wherein when the flipping part is in the stop position, the flipping part is located on the side of the push plate close to the baggage conveyor belt to stop the baggage; when the flipping part is in the clearance position, the flipping part is located on the side of the push plate away from the baggage conveyor belt to clearance the baggage; and a first drive structure disposed on the stop structure, the first drive structure being driven connected to the flipping part, the first drive structure being capable of driving the flipping part to rotate, thereby switching the flipping part between the stop position and the clearance position.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, 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 utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] like Figure 1As shown, this embodiment of the utility model provides a conveying device, which includes a support plate 100, a pusher plate 200, and a stop structure 300. The support plate 100 is disposed above a baggage conveyor belt, and the extending direction of the support plate 100 is perpendicular to the conveying direction of the baggage conveyor belt. The baggage conveyor belt is inclined in the width direction, and the support plate 100 is parallel to the baggage conveyor belt. The pusher plate 200 is movably disposed on the support plate 100, and the pusher plate 200 is capable of reciprocating along the height direction and along the extending direction of the support plate 100. A stop structure 300 is disposed on the push plate 200. The stop structure 300 has a flipping part 310, which has a stop position and a clearance position relative to the push plate 200. When the flipping part 310 is in the stop position, it is located on the side of the push plate 200 closer to the baggage conveyor belt to stop the baggage. When the flipping part 310 is in the clearance position, it is located on the side of the push plate 200 away from the baggage conveyor belt to avoid the baggage. The conveying device also includes a first drive structure 320 disposed on the stop structure 300. The first drive structure 320 is drivenly connected to the flipping part 310 and can drive the flipping part 310 to rotate, so that the flipping part 310 switches between the stop position and the clearance position.

[0025] When luggage flows along the luggage conveyor belt to the workstation of the conveyor device, the flipping part 310 can switch between a stop position and a clearance position under the drive of the first drive structure 320. When the luggage needs to be retrieved, that is, when it no longer needs to flow along the luggage conveyor belt, the first drive structure 320 drives the flipping part 310 to switch to the stop position. The luggage will stay on the luggage conveyor belt under the stop of the flipping part 310. At this time, the push plate 200 can push the luggage away from the luggage conveyor belt in a direction perpendicular to the luggage conveyor belt and transport the luggage to the next flow equipment or process. When the luggage does not need to be retrieved, that is, when it needs to continue to flow along the luggage conveyor belt, the first drive structure 320 drives the flipping part 310 to switch to the clearance position. The luggage will not be stopped by the flipping part 310 and will continue to move along the luggage conveyor belt.

[0026] By applying the technical solution of this application, the support plate 100 is arranged parallel to the inclined baggage conveyor belt. The pusher plate 200 moves back and forth along the extension direction of the support plate 100. With the limiting function of the stop structure 300, the baggage on the conveyor line can be aligned to the preset RFID re-inspection position, avoiding the positional displacement and dispersion of baggage caused by the tilt of the conveyor belt and differences in conveying posture. Furthermore, through the linkage control of the pusher plate 200 and the stop structure 300, it can adapt to various types of baggage and has no requirements on the spacing of the baggage. It does not require preset robot motion frequency based on baggage spacing, thus improving the operational efficiency of the baggage transfer process. In addition, the flipping part 310 switches between the stop position and the avoidance position through the first drive structure 320, which can adapt to the baggage transfer needs of different sizes and weights, and has stronger compatibility and versatility. Through the collaborative design of the support plate 100, the movable pusher plate 200 and the flipping stop structure 300, this application can effectively improve the efficiency of baggage transfer connection during the inclined baggage conveyor belt conveying process, while also ensuring the stability and safety of automated baggage transport.

[0027] Reference Figure 2 As shown, in one embodiment of this application, the first drive structure 320 includes a linear drive member 321 and a connecting rod 322. The output end of the linear drive member 321 is hinged to the connecting rod 322, and the connecting rod 322 is hinged to the flipping part 310. The hinged transmission method with the connecting rod 322 converts linear motion into rotational motion of the flipping part 310. The transmission path is clear and the stroke is controllable, ensuring that the flipping part accurately switches states within a preset angle range, thus improving the accuracy of luggage limiting and avoidance. Furthermore, the output force is stable, and combined with the force transmission characteristics of the connecting rod 322, it can smoothly drive the flipping part 310, avoiding luggage collisions or jamming caused by fluctuations in driving force, making it more suitable for the operation of inclined conveyor belts.

[0028] Specifically, the stop structure 300 also has a first connecting plate 330. The stop structure 300 is mounted on the push plate 200 via the first connecting plate 330, providing a stable mounting reference and connection interface for the flipping part 310, allowing it to be firmly fixed on the push plate 200. This enhances the overall rigidity and stability of the stop structure 300, enabling it to withstand external forces such as luggage impacts. The flipping part 310 has a first connecting shaft 311 and a second connecting shaft 312 arranged in parallel. The first connecting plate 330 is hinged to the flipping part 310 via the first connecting shaft 311, and the second connecting shaft 312 is hinged to the connecting rod 322. The revolute joint formed by the first connecting shaft 311 and the second connecting shaft 312 can separate the rotation connection point and the drive connection point of the flipping part 310, avoiding direct interference of the driving force on the rotation center of the flipping part. This provides precise motion constraints for the flipping part 310 to switch between the stop position and the avoidance position.

[0029] In one specific embodiment of this application, the linear drive 321 is an electric cylinder.

[0030] In other embodiments of this application, the linear drive 321 may also be a cylinder.

[0031] In other embodiments of this application, the first drive structure 320 is a rotary drive component, and the output end of the rotary drive component is fixedly connected to the push plate 200. This configuration simplifies the structure of the first drive structure 320, making it lighter and more aesthetically pleasing. The dead-point position of the blocking position prevents the electric cylinder and motor from being impacted by luggage, protecting the electric cylinder and extending its service life. It also makes the drive structure more compact, reduces intermediate transmission links, lowers transmission errors and failure risks caused by connecting rod hinge clearance and component wear, improves the overall reliability of the first drive structure 320's movement, reduces the number of parts, and lowers the overall production cost of the transmission device.

[0032] Specifically, the rotation drive can be a rotary motor.

[0033] Furthermore, a second drive structure 210 is provided between the push plate 200 and the support plate 100. The second drive structure 210 is driven to connect with the stop structure 300 to drive the push plate 200 to move in the height direction. By setting the second drive structure 210, the push plate 200 can be flexibly moved in the height direction, and the stop position can be adjusted according to the actual height of the luggage, effectively adapting to luggage of different heights. This prevents the stop from failing or tipping over due to luggage being too tall, or the stop structure from interfering with the conveyor belt due to luggage being too short. It optimizes the conveying posture and path of luggage on the inclined conveyor belt, reduces the risk of luggage collision and jamming, further improves luggage positioning accuracy, device operation flexibility and reliability, extends equipment service life and reduces maintenance costs, and ensures the efficient and smooth operation of the entire conveyor device.

[0034] Specifically, the second drive structure 210 includes a drive member and a rack. The rack 211 is mounted on the push plate 200. The drive member and the rack 211 are driven together, converting the driving force of the drive member into the linear lifting motion of the push plate 200. This allows the push plate 200 to be driven to a precise target height according to luggage of different heights, thereby ensuring effective blocking and avoidance of luggage of various sizes.

[0035] Optionally, the driving component can be a rotary motor or a linear motor, as long as it can drive the rack 211.

[0036] Specifically, the push plate 200 is provided with a first guide structure 220, which extends along the height direction. The push plate 200 is guided and cooperated with the support plate 100 through the first guide structure 220 to ensure that the movement trajectory of the push plate 200 deviates and to ensure the stability of the movement of the push plate 200.

[0037] Optionally, the first guide structure 220 can be a guide groove or guide rail, etc., as shown in the reference. Figure 2 As shown, in one embodiment of this application, the first guide structure 220 is a guide rail.

[0038] Similarly, a second connecting plate 120 is provided between the push plate 200 and the support plate 100. A third driving structure and a second guide structure 110 are provided between the second connecting plate 120 and the support plate 100. The third driving structure is driven to connect with the second connecting plate 120, and the second connecting plate 120 and the second guide structure 110 are guided together. On the one hand, this ensures that the push plate 200 can stably drive the stop structure 300 to move and straighten the luggage to the preset position. On the other hand, the guiding constraint of the second guide structure 110 prevents the push plate 200 from deviating or shaking during movement, ensuring the linearity and positional accuracy of the push plate 200's movement, and improving the reliability and stability of the push plate 200's movement.

[0039] Specifically, the third drive structure includes two linear modules, and the second guide structure 110 includes two parallel guide rails, each with a linear module. This configuration provides a smooth and sufficient driving force to the pusher 200 through the synchronous power output of the two linear modules, ensuring efficient reciprocating movement of the pusher along the guide rail extension direction. Furthermore, the guiding constraints of the parallel guide rails and the integrated layout of the linear modules further improve the straightness and positional accuracy of the pusher 200's movement, effectively preventing deviation, swaying, or jamming during pusher movement. Simultaneously, the symmetrical configuration of the two modules and two guide rails evenly distributes the load, enhancing the structural load-bearing capacity and operational stability, ensuring that the pusher drives the stop structure to accurately complete the baggage straightening operation, thereby improving the automated operation reliability and efficiency of the entire conveyor system.

[0040] like Figure 1 As shown, in some feasible embodiments of this application, a second connecting plate 120 is provided between the push plate 200 and the support plate. The push plate 200 is simultaneously mounted between two guide rails through the second connecting plate 120 and is connected to the linear module drive.

[0041] According to another aspect of this application, a baggage retrieval system is provided, comprising a conveying device, a sensor, and a controller. The conveying device is the aforementioned conveying device. The sensor is used to identify baggage information. The controller is electrically connected to both the sensor and a first drive structure 320. When the sensor identifies baggage information requiring transfer, the controller controls the flipping unit 310 to flip to a stop position; when the sensor identifies baggage information not requiring transfer, the controller controls the flipping unit 310 to flip to an avoidance position.

[0042] Specifically, the sensor can be a vision sensor or a coding sensor, etc.

[0043] In the baggage claim system provided by the present application, an automated collaborative architecture is formed by integrating the conveying device, the sensor and the controller. The sensor is responsible for accurately identifying baggage information and feeding back to the controller, and the controller realizes linkage control based on the identification result and the first driving structure: when the sensor identifies baggage to be transferred, the controller immediately issues an instruction to drive the turnover part to turn over to the stop position, so as to cooperate with the conveying device to complete the sorting and positioning of the baggage; when non-to-be-transferred baggage is identified, the controller controls the turnover part to switch to the avoidance position, so as to ensure that the baggage is normally conveyed without interference. This design realizes the full-process automated precise coordination of baggage identification, state judgment and stop structure action, which not only ensures the efficient positioning and transfer connection of the baggage to be transferred, but also avoids interference to the conveyance of non-target baggage, and significantly improves the automation degree, operation flexibility and overall operation efficiency of the baggage claim system.
