Description

Technical Field

[0001] This invention relates to the technical field of airport baggage empty basket recycling and processing systems, and more specifically to a baggage empty basket sorting device. Background Technology

[0002] With the increasing application of airport baggage empty basket recycling and processing systems, empty baskets on the recycling line are transported in stacks to improve system efficiency and increase storage capacity. Once the stacks reach the check-in counters, staff need to retrieve them individually. Currently, the unpacking and stacking of empty baskets is done manually, which is inefficient, labor-intensive, and lacks automation. Furthermore, with the rapid improvement of the national economy, labor costs are rising, undoubtedly increasing airport operating costs.

[0003] Currently used pallet or tote box sorting stations are primarily applicable to the logistics industry due to industry limitations. They handle regular items and have a relatively simple structure. In contrast, existing airport industry use 11-inch empty baggage trays, such as… Figure 1 and Figure 2 As shown, most of them have irregular shapes, with sloping surfaces along the length of the stacked surface and height differences at both ends along the width. This requires precise longitudinal (length) and lateral (width) positioning of the empty luggage baskets during the sorting process. Existing sorting station structures cannot meet the requirements of these irregular luggage baskets. At the same time, ordinary sorting stations generate a lot of noise during operation and their stability is not very good.

[0004] A search revealed that patents related to pallet sorting stations do not require precise positioning or baffles because the sorted items are pallets. However, the invention patent for a turnover box sorting station with application number "202211265344.6" uses an end-blocking mechanism for longitudinal positioning of the turnover boxes. Because the turnover boxes travel at high speeds, they bounce when they hit the baffles, causing inaccurate positioning and potentially damaging the boxes upon impact. While guide rails are used for lateral positioning, the gap between the rails and the turnover boxes is difficult to control, resulting in inaccurate lateral positioning. For irregularly shaped empty airport baggage crates, the gripping mechanism cannot properly pick them up, and the empty baggage crates cannot be neatly unpacked and stacked. In the utility model patent for a turnover box palletizing system with application number "202121540355.1", a baffle is set on the conveyor for longitudinal positioning, but it is not for positioning the turnover boxes, but for positioning the pallet. The turnover boxes are placed on the pallet, and the pallet is positioned laterally by setting blocks on the baffle to correspond to the forklift slots of the pallet. There is a gap between the forklift slots and the blocks, so the positioning is inaccurate and cannot ensure that the turnover boxes on the pallet are accurately positioned. Furthermore, this solution cannot achieve normal unpacking and palletizing of empty luggage baskets.

[0005] Therefore, how to provide a method that can achieve vertical alignment of empty luggage baskets、 Precise lateral positioning, avoiding damage to empty luggage baskets, stable and reliable operation, low noise, and a simple and compact structure are problems that urgently need to be solved by those skilled in the art. Summary of the Invention

[0006] In view of this, the present invention provides a method for realizing vertical movement of empty luggage baskets. 、 This luggage empty basket sorting device features precise lateral positioning, avoids damage to empty luggage baskets, boasts stable and reliable operation, low noise, and a simple and compact structure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A luggage empty basket sorting device, comprising:

[0009] frame;

[0010] A roller conveyor, arranged across the frame, is used to transport empty luggage baskets;

[0011] A material blocking device is installed on the roller conveyor and is used to longitudinally position the empty luggage basket;

[0012] A pushing device, which is installed on the roller conveyor, is used to laterally position the empty luggage basket;

[0013] The gripping mechanism consists of two gripping mechanisms, which are symmetrically arranged on both sides of the center line of the roller conveyor. The two gripping mechanisms are slidably connected to opposite sides of the frame and are used for lifting operations and gripping and releasing operations on the empty luggage baskets on the roller conveyor.

[0014] The lifting platform assembly is fixed at the bottom of the frame and located below the roller conveyor. The bottom ends of the two gripping mechanisms are respectively supported on the two lifting components of the lifting platform assembly to drive the two gripping mechanisms to lift and lower, so as to complete the stacking and unstacking operations of the empty luggage baskets.

[0015] The roller conveyor is equipped with a deceleration detection device for controlling the deceleration of the roller conveyor and a position detection device for controlling the stop of the roller conveyor along its conveying direction.

[0016] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a luggage empty basket sorting device. During stacking, the roller conveyor starts, and the first luggage empty basket is transported to the sorting station. When the luggage empty basket runs to the position of the deceleration detection device, the deceleration detection device is triggered. At this time, the speed of the roller conveyor begins to decelerate, and then the luggage empty basket begins to decelerate. When the luggage empty basket runs to the position of the positioning detection device, the positioning detection device is triggered. At this time, the roller conveyor stops running, and the blocking device rises to block the luggage empty basket, achieving longitudinal positioning of the luggage empty basket. Then, the pushing device moves to perform lateral positioning of the luggage empty basket, finally placing the luggage empty basket on the sorting station. At the same time, the gripping mechanism reaches the low position and grips the luggage empty basket. Then, the gripping mechanism lifts the first... The empty baggage basket is raised to a high position, making room for the second empty baggage basket to enter the stacking station. After the second empty baggage basket completes its longitudinal and lateral positioning according to the above steps, the gripping mechanism descends to the middle position. At this point, the first empty bag is placed on top of the second empty bag, completing the stacking of two empty bags. Then, the gripping mechanism stops gripping the baggage basket and descends to a low position while the pushing mechanism returns to its initial position. At this point, the gripping mechanism grabs the second empty baggage basket and lifts both empty bags back to a high position. The stacking of the next empty baggage basket is repeated in this manner. After stacking a stack of empty bags within the set stacking height range, the gripping mechanism stops gripping the baggage basket, and the material blocking device returns to its initial position. The roller conveyor restarts, and the stack of empty baggage baskets is transported out of the stacking station to enter the next cycle. The process of splitting the empty bag stack is the reverse of the stacking process and will not be described in detail here.

[0017] Therefore, this device, by installing a deceleration detection device, a positioning sensor, and a material blocking device on the roller conveyor, allows empty baggage baskets to slowly enter the sorting station, thus achieving precise longitudinal positioning of the empty baggage baskets and preventing them from being damaged by the material blocking device due to excessive speed, thereby protecting the empty baggage baskets from damage. By installing a pushing device on the roller conveyor, the device achieves lateral positioning of the empty baggage baskets, ensuring that the longitudinal centerline of the empty baggage basket coincides with the centerline of the roller conveyor, thus achieving precise lateral positioning of the empty baggage baskets. This allows the empty baggage baskets to be accurately positioned at the sorting station, enabling precise stacking and unpacking. This device enables automated sorting of irregularly shaped empty baggage baskets in the airport industry, replacing manual labor, improving system efficiency, and reducing labor costs.

[0018] Furthermore, the lifting platform assembly includes:

[0019] A lifting platform support is fixedly connected to the bottom of the frame and located below the roller conveyor. Three lifting proximity switches are installed at intervals on the lifting platform support.

[0020] A lifting motor, which is fixed on the lifting platform bracket;

[0021] A lifting drive shaft assembly is mounted on the lifting platform bracket and is connected to the output end of the lifting motor. Three lifting detection plates are installed at intervals on the lifting drive shaft assembly, and the three lifting detection plates are respectively arranged in correspondence with three lifting proximity switches to control the low, middle and high positions of the two gripping mechanisms during lifting. The two ends of the lifting drive shaft assembly are the lifting components.

[0022] The beneficial effects of adopting the above technical solution are: the lifting motor drives the lifting drive shaft assembly to rotate, and then the lifting components at both ends of the lifting drive shaft assembly drive the gripping mechanism to perform lifting and lowering actions.

[0023] Furthermore, a synchronous pulley for the lifting motor is fixed to the drive end of the lifting motor, and the lifting drive shaft assembly includes:

[0024] A lifting drive shaft is mounted on the lifting platform bracket via two bearings with mounting seats, and three lifting detection plates are mounted on the lifting drive shaft at intervals along its axial direction.

[0025] A lifting drive shaft synchronous pulley is fitted onto the lifting drive shaft, and the lifting drive shaft synchronous pulley is connected to the lifting motor synchronous pulley via a lifting synchronous belt drive.

[0026] Two rocker arms are provided, with one end of each rocker arm fixedly connected to both ends of the lifting drive shaft.

[0027] Two rocker arm rollers are rotatably mounted on the other end of the two rocker arms. The two rocker arm rollers are the two lifting components, and the bottom ends of the two gripping mechanisms are respectively supported on the two rocker arm rollers.

[0028] The beneficial effects of adopting the above technical solution are as follows: the drive motor drives the lifting drive shaft to rotate via the lifting synchronous belt, which in turn causes the rocker arm roller to rotate vertically around the lifting drive shaft, thereby lifting the gripping mechanism to perform lifting and lowering movements. This lifting platform assembly uses a rocker arm to realize the lifting and lowering action of the gripping mechanism. Its structure is simple, and it uses synchronous belt drive, which has high transmission efficiency, stable performance, and low noise.

[0029] Furthermore, both of the aforementioned grasping mechanisms include:

[0030] A gripping bracket has two lifting sliders fixed at intervals on one side surface. The two lifting sliders are slidably connected to two lifting guide rails fixed at intervals on one side of the frame. The bottom end of the gripping bracket is supported on the rocker arm roller. Two gripping proximity switches are fixed at intervals on the gripping bracket.

[0031] A fixing plate is fixed to the gripping bracket, and two gripping sliders are fixed at intervals at the top of the fixing plate;

[0032] The telescopic plate has two gripping guide rails fixed at a distance at its bottom end, and two gripping sliders are slidably connected to the two gripping guide rails respectively. A gripping detection plate is fixed at the top end of the telescopic plate, and the gripping detection plate corresponds to the positions of two gripping proximity switches and is used to control the extension and retraction positions of the telescopic plate. The side of the telescopic plate facing the empty luggage basket is detachably equipped with a flat fork plate for supporting the straight edge of the side end of the empty luggage basket and a slanted fork plate for supporting the inclined edge of the side end of the empty luggage basket.

[0033] A gripping motor, which is fixed on the gripping bracket;

[0034] A swing arm assembly, one end of which is connected to the drive end of the gripping motor and the other end of which is connected to the telescopic plate, is used to drive the telescopic plate to perform horizontal telescopic movement.

[0035] The beneficial effects of adopting the above technical solution are as follows: the gripping motor drives the telescopic plate to perform horizontal telescopic movement through the swing arm assembly, so that the flat fork plate and the diagonal fork plate on the telescopic plate can extend and retract together, realizing the gripping and release operation of the empty luggage basket; and the flat fork plate, the diagonal fork plate and the telescopic plate are detachably connected, so for empty luggage baskets with different shapes and structures, the flat fork plate and the diagonal fork plate can be flexibly replaced by changing the structural form of the flat fork plate and the diagonal fork plate, thereby improving the flexibility and applicability of the device.

[0036] Furthermore, a waist-shaped groove is formed on the top surface of the telescopic plate, and the swing arm assembly includes:

[0037] A swing arm, one end of which is fixedly connected to the drive end of the gripping motor, and the other end of which is fixed with a swing arm shaft;

[0038] A swing arm roller is mounted on the swing arm shaft and is located in the waist-shaped groove.

[0039] The beneficial effects of adopting the above technical solution are as follows: the gripping motor drives the rocker arm to rotate, causing the rocker arm roller to rotate horizontally around the output shaft of the gripping motor. Because the rocker arm roller slides in the oblong groove on the telescopic plate, it pushes the telescopic plate to perform a horizontal telescopic movement, which in turn moves the slanted fork and flat fork at the end of the telescopic plate, thus realizing the gripping and releasing action of the empty luggage basket. Therefore, this gripping mechanism uses a rotating arm to realize the telescopic movement of the slanted fork and flat fork, and its structure is simple and its operation is reliable.

[0040] Furthermore, the material blocking device includes:

[0041] A material stop bracket is installed on the roller conveyor, and two material stop proximity switches are vertically spaced on the material stop bracket;

[0042] The material blocking guide rail consists of two vertically spaced guide rails, one end of which is fixedly connected to the material blocking bracket.

[0043] A baffle plate is provided, with baffle sliders fixed on both sides. The two baffle sliders are slidably connected to the two baffle guide rails. The baffle plate is telescopically inserted between the gaps of the two rollers on the roller conveyor to contact the front end face of the empty luggage basket, thereby achieving longitudinal positioning of the empty luggage basket. A baffle detection plate is installed on the baffle plate, which corresponds to the positions of the two baffle proximity switches and is used to control the high and low positions of the baffle plate when it is raised and lowered.

[0044] A connecting rod, one end of which is connected to the baffle plate;

[0045] A material-stopping motor is fixed on the material-stopping bracket. A drive wheel is fixed to the drive end of the material-stopping motor, and the drive wheel is connected to the other end of the connecting rod.

[0046] The beneficial effects of adopting the above technical solution are as follows: the drive wheel of the baffle motor drives the connecting rod to move, and the connecting rod drives the baffle plate to lift and lower, thereby achieving longitudinal blocking and positioning of the empty luggage basket. Therefore, this baffle device uses a connecting rod to realize the extension and retraction of the baffle plate, and its structure is simple and its operation is reliable.

[0047] Furthermore, the baffle plate has a buffer pad on its baffle surface that flexibly contacts the front end face of the basket.

[0048] The beneficial effect of adopting the above technical solution is that the empty luggage baskets that are transported can be flexibly blocked by the cushioning pad, which can protect the empty baskets from damage.

[0049] Furthermore, the feeding device includes:

[0050] The guardrail is installed on one side of the roller conveyor via a guardrail bracket;

[0051] A pusher bracket is installed on the roller conveyor and located below the roller conveyor. Two pusher proximity switches are installed at intervals on the pusher bracket.

[0052] A pusher motor is fixed on the top surface of the pusher bracket and located below the roller conveyor. A pusher motor synchronous pulley is fixed on the drive end of the pusher motor.

[0053] A linear sliding platform is mounted on the top surface of the pusher bracket. The ball screw shaft of the linear sliding platform is fixed with a synchronous pulley. The synchronous pulley of the pusher motor is connected to the synchronous pulley of the linear sliding platform through a pusher synchronous belt drive.

[0054] A pusher plate is installed on the moving platform of the linear sliding platform to contact the side end face of the empty luggage basket, so as to push the empty luggage basket toward the guardrail, thereby realizing the lateral positioning of the empty luggage basket. A pusher detection plate is installed on the pusher plate, and the pusher detection plate and the two pusher proximity switches are used to control the extension and retraction positions of the pusher plate.

[0055] The beneficial effects of adopting the above technical solution are as follows: The pusher motor drives the ball screw on the linear sliding platform to rotate via the pusher timing belt, which in turn moves the moving platform on the linear sliding platform, causing the pusher plate on it to move. The pusher plate then pushes the empty luggage baskets until they are blocked by the guardrail, achieving lateral positioning of the empty luggage baskets and ensuring that the longitudinal centerline of the empty luggage baskets coincides with the centerline of the roller conveyor, i.e., accurately positioned at the sorting station. Furthermore, during the destacking operation, through the clamping action of the pusher plate and the guardrail, the gripping mechanism can smoothly fork up the empty baskets above the first empty basket in the stack and lift them using the lifting platform assembly, thus conveying the first basket out. This achieves rapid separation of the empty luggage baskets, solving the problem of empty luggage baskets sticking together and being difficult to separate.

[0056] Furthermore, both sides of the roller conveyor are fixedly connected to both sides of the frame via connecting brackets.

[0057] The beneficial effects of adopting the above technical solution are: the roller conveyor is connected to the frame as a whole through the connecting bracket, making the whole equipment compact, simple, symmetrical, and easy to install and debug.

[0058] Furthermore, an over-height detection device is installed on the top of the rack to detect the stacking height of the empty luggage baskets.

[0059] The beneficial effects of adopting the above technical solution are: the stacking height of empty luggage baskets can be detected, and when the stacking reaches the predetermined height, the device stops the stacking operation to avoid the danger of the stacking collapsing and injuring people due to excessive height.

[0118] The deceleration detection device 9, the positioning detection device 10, and the over-height detection device 8 mentioned above can all be sensors capable of performing their detection functions, such as infrared sensors or proximity switch sensors.

[0119] like Figure 14 The working principle of the luggage empty basket stacking device of the present invention during stacking is explained as follows:

[0120] Roller conveyor 4 starts, and the first empty luggage basket 11 is transported to the sorting station. The deceleration detection device 9 is triggered, and the empty luggage basket 11 begins to decelerate. When it reaches the positioning detection device 10, the roller conveyor 4 stops. At the same time, the baffle plate 5-7 rises and blocks the empty luggage basket 11, achieving longitudinal positioning of the empty luggage basket 11. This ensures that the transverse centerline of the empty luggage basket 11 coincides with the centerline of the frame 1. Then, the pusher plate 6-6 pushes the empty luggage basket 11 laterally until it is blocked by the guardrail 6-10, achieving transverse positioning of the empty luggage basket 11. This ensures that the longitudinal centerline of the empty luggage basket 11 coincides with the centerline of the roller conveyor 4, ultimately achieving precise longitudinal and transverse positioning of the empty luggage basket 11, allowing it to move accurately to the sorting station. Then, the pusher plate 6-6 retracts, and simultaneously, the gripping mechanism 3 reaches its low position. The slanted fork 3-8 and the flat fork 3-9 extend and grip the empty luggage basket 11. The gripping mechanism 3 lifts the first empty luggage basket 11 to its high position, making room for the second empty luggage basket 11 to enter the stacking station. After the second empty luggage basket 11 completes its longitudinal and lateral positioning according to the above steps, the gripping mechanism 3 descends to its middle position. At this point, the first empty luggage basket 11 is placed precisely on top of the second empty luggage basket 11, completing the stacking of the two empty luggage baskets 11. Then, the slanted fork 3-8... 8. The flat fork plate 3-9 retracts, the gripping mechanism 3 lowers to the low position, and the pusher plate 6-6 retracts. At this time, the slanted fork plate 3-8 and the flat fork plate 3-9 extend into the second empty luggage basket 11 again. The gripping mechanism 3 lifts the two empty luggage baskets 11 to the high position. The stacking of the next empty luggage basket is carried out in the same way. After a stack of empty baskets is completed within the set stacking height range, the slanted fork plate 3-8 and the flat fork plate 3-9 retract, and the baffle plate 5-7 lowers to the low position. The roller conveyor 4 starts, and the stack of empty baskets is transported out of the stacking station and enters the next cycle.

[0121] like Figure 15 As shown, the working process of the luggage empty basket sorting device of the present invention during unstacking is the opposite of that during stacking, and will not be described again here.

[0122] The advantages of this invention are as follows:

[0123] (1) In this invention, by setting a deceleration detection device 9 and a baffle device 5 on the roller conveyor 4, and setting a buffer pad 5-7a on the part of the baffle plate 5-7 that contacts the empty basket, the empty bag 11 is slowly entered into the sorting station and is flexibly blocked, thereby achieving accurate longitudinal positioning of the empty basket and protecting the empty basket from damage; by setting a pusher device 6 on the roller conveyor 4, the lateral positioning of the empty bag 11 is achieved, ensuring that the longitudinal center line of the empty bag 11 coincides with the center line of the roller conveyor. In the destacking operation, the clamping action of the pusher plate 6-6 and the guardrail 6-10 is used to achieve rapid separation of the empty bag, so as to solve the problem that the empty bag is sucked together and difficult to separate; in the gripping mechanism 3, the inclined fork plate 3-8, the flat fork plate 3-9 and the telescopic plate 3-4 are designed separately and connected to them by fasteners such as bolts. For empty bags with different shapes and structures, flexible replacement can be achieved by changing the structure of the fork plate. These technological solutions enable automated sorting of irregularly shaped empty baggage baskets in the airport industry, replacing manual labor, improving system efficiency, and reducing labor costs.

[0124] (2) The lifting motion of the gripping mechanism 3 in this invention adopts a rocker arm in conjunction with a vertical linear slide rail, the telescopic motion of the gripping mechanism 3 adopts a rotating arm in conjunction with a horizontal linear slide rail, and the lifting motion of the blocking device 5 adopts a connecting rod in conjunction with a vertical linear slide rail. All mechanisms are driven by a drive motor, so that the equipment operates stably and reliably.

[0125] (3) In this invention, the lifting of the gripping mechanism 3 and the lateral movement of the pusher plate 6-6 are both driven by synchronous belt, which has high transmission efficiency, stable performance and low noise.

[0126] (4) The ultra-high detection device 8 in this embodiment is used for safety detection of the stacking height to ensure the stability and reliability of the equipment.

[0127] (5) In this invention, the roller conveyor and the frame are connected as a whole, making the whole equipment compact, simple, symmetrical, and easy to install and debug.
