Description

Technical Field

[0001] This invention relates to the field of airport logistics technology, and more specifically to a baggage handling palletizing device and method. Background Technology

[0002] In the entire airport baggage handling process, departing baggage needs to be sorted and transported to the baggage carousel at the terminal. The next step involves baggage trolleys moving the baggage to the tarmac and then loading it onto the aircraft. Transferring baggage from the carousel to the trolleys is a time-consuming and labor-intensive process. Based on this need, some airports have adopted robotic arms for baggage transfer, while others still use manual handling. Manual handling is inefficient and physically demanding, reflecting high labor costs. While robotic arms can significantly improve efficiency and reduce labor costs, they also have drawbacks. First, robotic arms are generally large, and baggage of varying hardness may be damaged. Furthermore, robotic arms cannot ensure tight spacing between baggage when picking it up from the carousel and moving it to the trolley, wasting trolley space. Second, baggage may tilt or tip over during stacking on the trolley, increasing the difficulty of stacking and further wasting trolley space. Therefore, it may be necessary to increase the number of trolley sections or the number of trips to complete the baggage transfer as quickly as possible.

[0003] Although CN208699895U discloses a passenger baggage handling device, this method can only help save manpower. The entire baggage handling process still requires human intervention, including the process of moving the baggage from the carousel to the auxiliary device, then to the baggage trolley, and finally to the stacking of the baggage. It is inefficient and has high labor costs.

[0004] CN211338051U discloses a baggage transfer device. Although this method can improve the efficiency of baggage transfer from the baggage tray to the trailer and can also achieve automatic stacking, it still does not solve the problem of tight baggage gaps. It is still necessary to increase the number of baggage trailer sections or the number of baggage trailer transfers to improve the efficiency of baggage transfer to the apron. Summary of the Invention

[0005] The purpose of this invention is to provide a palletizing device and method for handling luggage, addressing the aforementioned problems.

[0006] The technical solution of the present invention is as follows:

[0007] A baggage handling and palletizing device includes a lifting module, a receiving module, and a pushing module. The lifting module includes a bottom support plate and a top support plate arranged parallel to each other. A lifting mechanism and a support column are provided between the bottom support plate and the top support plate. The lifting mechanism drives the receiving module and the pushing module to move up and down. The receiving module is set on the lifting platform of the lifting mechanism and includes a receiving plate that can slide back and forth to transport baggage. The pushing module includes a pushing lifting mechanism and a pushing mechanism. The pushing lifting mechanism is fixedly set on the receiving module through a pushing lifting guide rail and a pushing lifting rack. The pushing mechanism is fixedly set on the pushing support plate of the pushing lifting mechanism. The lifting mechanism raises and lowers the position of the receiving plate and the pushing module. The receiving plate slides back and forth to transport neatly arranged baggage. The pushing mechanism adjusts its position through the pushing lifting mechanism to push a single neatly arranged baggage or multiple neatly arranged bags into a baggage trolley.

[0008] Furthermore, the pushing mechanism includes a pushing drive assembly mounted on a pushing support plate. The pushing drive assembly includes a pushing fixed block, a pushing drive screw rotatably mounted in the shaft hole of the pushing fixed block, a pushing power source driving the pushing drive screw, and a scissor fork driving slider slidably mounted on the pushing drive screw. The scissor fork driving slider has a helical structure matching the pushing drive screw. A scissor fork fixed block is also fixedly mounted on the upper surface of the pushing fixed block. A pushing plate is mounted on the opposite side of the pushing drive assembly, and a scissor fork mechanism is mounted between the pushing drive assembly and the pushing plate. The pushing power source drives the pushing drive screw to rotate, thereby driving the scissor fork driving slider to move, causing the scissor fork mechanism to extend or retract the pushing plate.

[0009] Furthermore, the pusher plate is provided with a slide rail and a fixed rotating plate, and a slider is slidably connected on the slide rail; one end of the scissor fork machine is rotatably mounted on the scissor fork fixing block and the scissor fork drive slider, and the other end is rotatably mounted on the slider and the fixed rotating plate.

[0010] Furthermore, the material pushing support plate is slidably mounted on the material pushing lifting guide rail and the material pushing lifting rack. A material pushing lifting power source is fixedly mounted on the upper surface of the material pushing support plate, and the material pushing lifting power source is driven by a material pushing lifting drive gear. Two material pushing shaft seats are provided on the lower surface of the material pushing support plate. A material pushing lifting synchronous shaft is rotatably mounted in the shaft hole of the material pushing shaft seat. Material pushing lifting gears are fixedly mounted at both ends of the material pushing lifting synchronous shaft. The material pushing lifting gear at one end cooperates with the material pushing lifting drive gear to transmit power, and the material pushing lifting gears at both ends mesh with the material pushing lifting rack. The material pushing support plate is driven to move up and down along the material pushing lifting guide rail and the material pushing lifting rack by the material pushing lifting power source.

[0011] Furthermore, a receiving fixing plate is slidably connected to both sides of the receiving plate, and the two receiving fixing plates are vertically arranged on the lifting platform; a receiving power source and a receiving gear are arranged under the receiving plate, and the receiving gear is coaxially fixedly installed on the rotating shaft of the receiving power source, which is fixedly installed on the upper surface of the lifting platform; the receiving gear meshes with the rack structure arranged on the lower surface of the receiving plate; the receiving power source drives the receiving plate to move back and forth.

[0012] Furthermore, the material pushing and lifting guide rails and the material pushing and lifting racks are symmetrically fixed and welded to the outer sides of the two receiving and fixing plates; and there are four material pushing and lifting guide rails and two material pushing and lifting racks.

[0013] Furthermore, the lifting mechanism includes large shaft seats disposed on the upper surface of the bottom support plate and the upper surface of the top support plate; four large shaft seats on the upper surface of the top support plate are arranged along the same horizontal line, and an active lifting shaft is rotatably installed in the rotating holes of the two large shaft seats at one end. One end of the active lifting shaft is also connected to a lifting power source, and a pulley is also connected to the active lifting shaft; a secondary lifting shaft is disposed in the rotating holes of the two large shaft seats at the other end, and a pulley is connected to the secondary lifting shaft; a primary lifting shaft is rotatably installed in the rotating holes of the two large shaft seats on the upper surface of the bottom support plate, and two pulleys coaxially disposed on the primary lifting shaft are respectively connected to the pulley on the active lifting shaft and the pulley on the secondary lifting shaft via synchronous belt drives.

[0014] Furthermore, the lifting mechanism also includes lifting guide rails disposed between the bottom support plate and the top support plate, and the lifting platform is slidably disposed on the four lifting guide rails; a synchronous belt passes through the lifting platform and is fixedly connected to a lifting fixing block fixedly installed on the lifting platform; the lifting platform can be moved up and down by a lifting power source.

[0015] Furthermore, the active lifting shaft and the secondary lifting shaft are both parallel to the primary lifting shaft and located on the same horizontal plane; the lifting guide rails are perpendicular to the bottom support plate and the top support plate, respectively.

[0016] This application also includes a baggage handling and stacking method, comprising the following steps:

[0017] After the luggage trolley arrives at the luggage loading area, the position detection device transmits the position information of the luggage trolley to the control system. The control system then moves the robotic arm and the empty / tight palletizing device to the appropriate positions based on the robotic arm guide rail and the empty / tight palletizing device guide rail. Before the luggage on the luggage carousel reaches the designated position, the robotic arm waits to clamp the luggage, and the empty / tight palletizing device resets to wait to receive the luggage. After the robotic arm has clamped the luggage, the luggage placement posture will be adjusted during the luggage transfer process. The shape and weight information of the posture adjustment are obtained by the DWS system at the front end of the luggage carousel.

[0018] The empty palletizing device resets, and the lifting power source drives the active lifting shaft to rotate, which in turn drives the pulley to rotate, which in turn drives the synchronous belt to rotate. The synchronous belt then drives the lower pulley to rotate, which in turn drives the primary lifting shaft to rotate. This drives the pulley at the other end of the primary lifting shaft to rotate, which in turn drives the other synchronous belt to rotate, achieving synchronous rotation of the two synchronous belts. The lifting platform is fixed to the two synchronous belts by the lifting fixing block. The lifting platform rises and falls with the rotation of the synchronous belts, causing the receiving plate to rise and fall to the height where the luggage is about to be placed. The receiving power source drives the receiving gear to rotate. The receiving gear meshes with the rack inside the receiving plate, driving the receiving plate to move towards the robotic arm. At the same time, the pushing lifting power source drives the pushing lifting active gear to rotate, which in turn drives the pushing lifting gear, the pushing lifting synchronous shaft, and the other pushing lifting gear to rotate. The two pushing lifting gears mesh with the pushing lifting rack, thereby driving the pushing support plate and its components to rise, making room for the receiving plate to place the luggage.

[0019] The robotic arm grips and transfers luggage onto the receiving plate. Driven by the receiving power source, the receiving plate and the luggage above it move towards the luggage trailer. Once in place, driven by the pushing and lifting power source, the pushing support plate descends to a predetermined position above the receiving plate. Then, the pushing power source drives the scissor fork to move the slider in the clamping direction, thereby driving the scissor fork mechanism to extend and push against the pushing plate to push the luggage out, thus pushing the luggage to the position where it needs to be placed on the luggage trailer.

[0020] After the luggage is pushed, the receiving plate is driven and transmitted by the power source to move a certain distance towards the robotic arm. The pushing power source drives and transmits the scissor fork mechanism to retract, so that the pushing plate is reset. The receiving plate is driven to continue to move and reset towards the robotic arm.

[0021] The pusher support plate and its upper components are driven to rise and reset.

[0022] Enter the next baggage palletizing cycle.

[0023] Compared with existing technologies, the advantages of this invention are:

[0024] A baggage handling and palletizing device and method are disclosed. For manual handling, only manual labor is required to move baggage from the baggage carousel to the compaction and expansion device, saving the manpower required to move baggage from the baggage carousel to the baggage trolley and to palletize the baggage. For robotic arm handling, baggage can be compactly palletized on the baggage trolley, increasing the space utilization of the baggage trolley and improving handling efficiency without increasing the number of baggage trolley sections or the number of handling operations.

[0039] After the robotic arm 8 finishes picking up the luggage, it will adjust the luggage's placement posture during the luggage transfer process. The shape and weight information of the posture adjustment are obtained by the DWS system 41 at the front end of the luggage carousel 10.

[0040] like Figure 4As shown, the pushing mechanism includes a pushing drive assembly mounted on a pushing support plate 33. The pushing drive assembly includes a pushing fixing block 313.

The pusher lifting gear 312 at one end cooperates with the pusher lifting drive gear 311 to transmit power, and the pusher lifting gears 312 at both ends mesh with the pusher lifting rack 32. The pusher support plate 33 is driven to move up and down along the pusher lifting guide rail 31 and the pusher lifting rack 32 by the pusher lifting power source 310.

[0043] like Figure 3 As shown, receiving plates 21 are slidably connected to both sides of the receiving plate 24, and the two receiving plates 21 are vertically arranged on the lifting platform 111; a receiving power source 22 and a receiving gear 23 are arranged under the receiving plate 24, and the receiving gear 23 is coaxially fixedly installed on the rotating shaft of the receiving power source 22, which is fixedly installed on the upper surface of the lifting platform 111; the receiving gear 23 meshes with the rack structure provided on the lower surface of the receiving plate 24; the receiving plate 24 is driven to move back and forth through the receiving power source 22.

[0044] The material lifting guide rail 31 and the material lifting rack 32 are symmetrically fixed and welded to the outside of the two receiving and fixing plates 21; and there are four material lifting guide rails 31 and two material lifting racks 32.

[0045] like Figure 2 As shown, the lifting mechanism includes large shaft seats 14 disposed on the upper surface of the bottom support plate 11 and the upper surface of the top support plate 13; four large shaft seats 14 on the upper surface of the top support plate 13 are arranged along the same horizontal line, and an active lifting shaft 15 is rotatably installed in the rotating holes of the two large shaft seats 14 at one end. One end of the active lifting shaft 15 is also connected to the lifting power source 18, and a pulley 16 is also connected to the active lifting shaft 15; a secondary lifting shaft 19 is disposed in the rotating holes of the two large shaft seats 14 at the other end, and a pulley 16 is connected to the secondary lifting shaft 19; a primary lifting shaft 112 is rotatably installed in the rotating holes of the two large shaft seats 14 on the upper surface of the bottom support plate 11, and two pulleys 16 coaxially disposed on the primary lifting shaft 112 are respectively connected to the pulley 16 on the active lifting shaft 15 and the pulley 16 on the secondary lifting shaft 19 through a synchronous belt 17.

[0046] The lifting mechanism also includes lifting guide rails 110 disposed between the bottom support plate 11 and the top support plate 13, and the lifting platform 111 is slidably disposed on the four lifting guide rails 110; the synchronous belt 17 passes through the lifting platform 111, and the synchronous belt 17 is fixedly connected to the lifting fixing block 113 fixedly installed on the lifting platform 111; the lifting power source 18 can drive the lifting platform 111 to move up and down.

[0047] The active lifting shaft 15 and the secondary lifting shaft 19 are both parallel to the primary lifting shaft 112 and located on the same horizontal plane; the lifting guide rail 110 is perpendicular to the bottom support plate 11 and the top support plate 13, respectively.

[0048] In another specific embodiment, this application also includes a baggage handling palletizing method, such as... Figure 7 As shown, it includes the following steps:

[0049] After the luggage trolley 9 arrives at the luggage loading area, the position detection device detects and transmits the position information of the luggage trolley 9 to the control system. The control system then moves the robotic arm 8 and the empty stacking device 5 to the appropriate positions based on the robotic arm guide rail 6 and the empty stacking device guide rail 4. Before the luggage 7 on the luggage carousel 10 reaches the designated position, the robotic arm 8 waits to clamp the luggage, and the empty stacking device 5 resets to wait to receive the luggage. After the robotic arm 8 clamps the luggage, it will adjust the luggage placement posture during the luggage transfer process. The shape and weight information of the posture adjustment are obtained by the DWS system 41 at the front end of the luggage carousel 10.

[0050] The empty stacking device 5 resets, and the lifting power source 18 drives the active lifting shaft 15 to rotate, which in turn drives the pulley 16 to rotate, which in turn drives the synchronous belt 17 to rotate. The synchronous belt 17 then drives the lower pulley 16 to rotate, which in turn drives the lifting primary shaft 112 to rotate, which in turn drives the pulley 16 at the other end of the lifting primary shaft 112 to rotate, which in turn drives the other synchronous belt 17 to rotate, thus achieving synchronous rotation of the two synchronous belts 17. The lifting platform 111 is fixed to the two synchronous belts 17 by the lifting fixing block 113. The lifting platform 111 rises and falls with the rotation of the synchronous belts 17, which in turn drives the receiving plate 24 to rise and fall until the luggage is about to be placed. The height position is determined by the following: the power source 22 drives the receiving gear 23 to rotate, and the receiving gear 23 meshes with the rack inside the receiving plate 24, driving the receiving plate 24 to move towards the robotic arm; at the same time, the material pushing and lifting power source 310 drives the material pushing and lifting drive gear 311 to rotate, driving the material pushing and lifting gear 312, the material pushing and lifting synchronous shaft 317, and the other end of the material pushing and lifting gear 312 to rotate, and the two material pushing and lifting gears 312 mesh with the material pushing and lifting rack 32, thereby driving the material pushing support plate 33 and its components to rise, making room for the receiving plate to place luggage;

[0051] The robotic arm 8 grips and transfers the luggage onto the receiving plate 24. Driven by the receiving power source 22, the receiving plate 24 and the luggage 7 above it move towards the luggage trailer 9. After moving into place, the pushing and lifting power source 310 drives the pushing support plate 33 to descend to a predetermined position above the receiving plate 24. Then, the pushing power source 34 drives the scissor fork drive slider 315 to move in the clamping direction, thereby driving the scissor fork mechanism 38 to extend and push against the pushing plate 35 to push it out, pushing the luggage 7 to the position where the luggage needs to be placed on the luggage trailer 9.

[0052] After the luggage is pushed, the power source 22 drives and transmits the receiving plate 24 to move a certain distance in the direction of the robotic arm 8. The pushing power source 34 drives and transmits the scissor fork mechanism 38 to retract, so that the pushing plate 35 is reset. The receiving plate 24 continues to move and reset in the direction of the robotic arm 8 after being driven.

[0053] The pusher support plate 33 and its upper components are driven to rise and reset.

[0054] Enter the next baggage palletizing cycle.

[0055] For manual handling, only manpower is needed to move luggage from the luggage carousel to the compact expansion device, saving manpower for moving luggage from the luggage carousel to the luggage trolley and for stacking luggage; for robotic arm handling, luggage can be compactly stacked on the luggage trolley, increasing the space utilization of the luggage trolley and improving handling efficiency without increasing the number of luggage trolley sections or handling times.

[0056] The embodiments described above merely illustrate specific implementation methods of this application, and while the descriptions are detailed and specific, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the technical solution of this application, and these modifications and improvements all fall within the scope of protection of this application.

A baggage handling palletizing device according to claim 6, characterized in that, The active lifting shaft (15) and the secondary lifting shaft (19) are both parallel to the primary lifting shaft (112) and located on the same horizontal plane; the lifting guide rail (110) is perpendicular to the bottom support plate (11) and the top support plate (13) respectively.

8. A method for stacking luggage during handling, characterized in that, Includes the following steps: After the luggage trolley (9) arrives at the luggage loading area, the position detection device detects and transmits the position information of the luggage trolley (9) to the control system. The control system moves the robotic arm (8) and the empty stacking device (5) to the position based on the robotic arm guide rail (6) and the empty stacking device guide rail (4). Before the luggage (7) on the luggage carousel (10) reaches the designated position, the robotic arm (8) waits to clamp the luggage, and the empty stacking device (5) resets to wait to receive the luggage. After the robotic arm (8) clamps the luggage, it will adjust the luggage placement posture during the luggage transfer process. The shape and weight information of the posture adjustment are obtained by the DWS system (41) at the front end of the luggage carousel (10). The empty stacking device (5) is reset, and the lifting power source (18) drives the active lifting shaft (15) to rotate, which drives the pulley (16) to rotate, which drives the synchronous belt (17) to rotate. Then, the synchronous belt (17) drives the lower pulley (16) to rotate, which drives the lifting primary shaft (112) to rotate, which drives the pulley (16) at the other end of the lifting primary shaft (112) to rotate, which drives the other synchronous belt (17) to rotate, so that the two synchronous belts (17) rotate synchronously. The lifting platform (111) is fixed on the two synchronous belts (17) by the lifting fixing block (113). The lifting platform (111) is lifted and lowered with the rotation of the synchronous belt (17), which drives the receiving plate (24) to rise and fall. The height position of the luggage to be placed; the receiving power source (22) drives the receiving gear (23) to rotate, the receiving gear (23) meshes with the rack inside the receiving plate (24) to drive the receiving plate (24) to move towards the robotic arm; at the same time, the pushing lifting power source (310) drives the pushing lifting drive gear (311) to rotate, drives the pushing lifting gear (312), the pushing lifting synchronous shaft (317) and the other pushing lifting gear (312) to rotate, the two pushing lifting gears (312) mesh with the pushing lifting rack (32) to drive the pushing support plate (33) and its components to rise, making room for the receiving plate to place the luggage; The robotic arm (8) grips and transfers the luggage to the receiving plate (24). Driven by the receiving power source (22), the receiving plate (24) and the luggage (7) above it move towards the luggage trailer (9). After moving into place, driven by the pushing lifting power source (310), the pushing support plate (33) is lowered to a predetermined position above the receiving plate (24). Then, the pushing power source (34) drives the scissor fork drive slider (315) to move in the clamping direction, thereby driving the scissor fork mechanism (38) to extend and press against the pushing plate (35) to push it out, pushing the luggage (7) to the required placement position. After the luggage is pushed, the receiving power source (22) drives and transmits the receiving plate (24) to move a distance in the direction of the robotic arm (8), the pushing power source (34) drives and transmits the scissor fork mechanism (38) to retract, so that the pushing plate (35) is reset, and the receiving plate (24) continues to move and reset in the direction of the robotic arm (8) through the drive. The pusher support plate (33) and its upper components are driven to rise and reset; Enter the next baggage palletizing cycle.
