[0002] With the rapid development of the international community, both work and leisure travel are inseparable from transportation such as airplanes, shipping, and cars. To prevent public hazards, passenger terminals for each mode of transportation must inspect passengers' checked and carry-on luggage. If any prohibited items are found, the luggage must be intercepted and ultimately returned to the owner, achieving effective baggage control. Therefore, a lock is used to seal the luggage.

[0003] CN115072028A discloses an automatic luggage packing device and a method for packing luggage, which can replace manual work to automatically unlock, stretch the sealing tape, and seal the luggage. However, the automatic luggage packing device and the method for packing luggage have the disadvantage of complicated operations. The pre-packing steps can only be completed by first unlocking the sealing tape, pulling out the sealing tape, wrapping it around, and then inserting the lock buckle into the sealing tape.

[0045] In order to make the technical problems, technical solutions and beneficial effects to be solved by this application more clearly understood, this application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0047] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0048] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0049] Please also refer to Figures 1 to 7The automatic sealing mechanism 100 provided in the embodiment of the present application is now described. The automatic sealing mechanism 100 comprises:

[0050] Transverse drive structure 10;

[0051] The first pushing mechanism 20 and the second pushing mechanism 30 are connected to the horizontal driving structure 10 at the same time, and are symmetrically provided with an upper telescopic member 21, a lower telescopic member 22 and a first vertical driving structure 23, respectively. The lower telescopic member 22 is provided to be connected to the first vertical driving structure 23;

[0052] The manipulator mechanism 40 includes a second vertical driving structure 41 and a mechanical claw 42 . The second vertical driving structure 41 is disposed on the first pushing mechanism 20 , and the mechanical claw 42 is connected to the second vertical driving structure 41 .

[0053] It can be understood that, since the first pushing mechanism 20 and the second pushing mechanism 30 are simultaneously connected to the transverse driving structure 10 , the transverse driving structure 10 can simultaneously drive the first pushing mechanism 20 and the second pushing mechanism 30 to perform transverse movement.

[0054] The manipulator mechanism 40 grasps the sealing block through the mechanical claw 42 and can unlock the sealing block and tighten the sealing belt, such as the mechanical claw 42 structure in publication number CN115072028A. The second vertical drive structure 41 can drive the mechanical claw 42 to move vertically.

[0055] Since the first pushing mechanism 20 and the second pushing mechanism 30 are symmetrically arranged and have the same function, the second vertical driving structure 41 is arranged on the first pushing mechanism 20, which can also be understood as the second vertical driving structure 41 being arranged on the second pushing mechanism 30, and should both fall within the scope of protection of the application.

[0056] Thus, based on the automatic sealing mechanism 100, in the initial state, the first pushing mechanism 20 and the second pushing mechanism 30 are located close to each other, and the lower telescopic member 22 is aligned with the sealing block on the mechanical claw 42. The following sealing method can be performed to seal the luggage. The sealing method includes the following steps:

[0057] Step 1: The mechanical claw 42 grabs and seals the device.

[0058] It is understandable that if Figure 1As shown, from top to bottom, the first, second, and third generation of the seal lock 300 are shown. If it is a first generation seal lock 300, its initial state is the locked state, and the sealing tape forms an initial sealing ring, which can be directly grasped by the mechanical claw 42. If it is a second generation seal lock 300, it only needs to be locked in advance, that is, the lock buckle is inserted into the lock core to form an initial sealing ring, and then it can be grasped by the mechanical claw 42. If it is a third generation seal lock 300, since it has no lock buckle structure, its initial state is the locked state, and the sealing tape forms an initial sealing ring, it can also be directly grasped by the mechanical claw 42.

[0059] Step 2: The lower telescopic members 22 on the first pushing mechanism 20 and the second pushing mechanism 30 are extended and inserted into the sealing ring of the sealing block 300 .

[0060] Step 3: The second vertical driving structure 41 drives the mechanical claw 42 to move upward to stretch the sealing ring.

[0061] It is understandable that when the pair of lower telescopic members 22 are inserted into the sealing ring of the sealing block 300, the mechanical claws 42 drive the sealing block 300 to move upward, which will generate tension on the sealing belt, causing the sealing ring to expand for the first time.

[0062] Step 4: The upper telescopic members 21 on the first pushing mechanism 20 and the second pushing mechanism 30 are extended and inserted into the sealing ring of the sealing block 300 .

[0063] It can be understood that after the sealing ring is expanded for the first time, the shape of the sealing ring can be regarded as a trapezoid that is narrow at the top and wide at the bottom, so that the pair of upper telescopic members 21 can be inserted into the sealing ring of the seal block 300. In this way, the pair of upper telescopic members 21 and the pair of lower telescopic members 22 are both located in the sealing ring, and the basic conditions for stretching the sealing ring again are met.

[0064] In step 5, the transverse driving structure 10 drives the first pushing mechanism 20 and the second pushing mechanism 30 to move in opposite directions, and the first vertical driving structure 23 drives the lower telescopic member 22 to move downward, stretching the sealing ring again.

[0065] It can be understood that the transverse driving structure 10 drives the first pushing mechanism 20 and the second pushing mechanism 30 to move backward, which can drive the pair of upper telescopic members 21 and the pair of lower telescopic members 22 to move backward, gradually stretching the sealing ring and expanding the width of the sealing ring; and the first vertical driving structure 23 drives the lower telescopic member 22 to move downward, thereby increasing the distance between the upper telescopic member 21 and the lower telescopic member 22, gradually stretching the sealing ring and expanding the height of the sealing ring. In this way, after the sealing ring is stretched again, the sealing ring can form a shape that is approximately a large square, ensuring that luggage of different sizes can enter the sealing ring for sealing.

[0066] Step 6: Wait for the luggage to enter the sealing circle.

[0067] It is understandable that steps 1 to 5 can be prepared before the luggage is in place, and the tightening action of steps 7 to 9 can be directly performed after the luggage enters the sealing circle, which is conducive to improving the sealing efficiency.

[0068] In step 7, the first vertical driving structure 23 first drives the lower telescopic member 22 to move upward for a distance, and then the lower telescopic members 22 on the first pushing mechanism 20 and the second pushing mechanism 30 are respectively retracted, and the sealing ring 300 is retracted.

[0069] It can be understood that the first vertical driving structure 23 first drives the lower telescopic member 22 to move upward for a distance, and the sealing ring 300 initially contracts. After the lower telescopic member 22 contracts, the sealing ring 300 contracts again, and contracts in stages to prevent the sealing belt from suddenly loosening, so as to avoid interference caused by pulling of the sealing belt by other components in the equipment.

[0070] In step 8, the upper telescopic members 21 on the first pushing mechanism 20 and the second pushing mechanism 30 are respectively retracted, and the transverse driving structure 10 then drives the first pushing mechanism 20 and the second pushing mechanism 30 to move toward each other, and the sealing ring 300 is retracted again.

[0071] It is understandable that the upper telescopic members 21 are first contracted, and the transverse driving structure 10 first drives the first pushing mechanism 20 and the second pushing mechanism 30 to move toward each other, so as to gradually contract the width of the sealing ring.

[0072] In step 9, the second vertical driving structure 41 drives the mechanical claw 42 to move downward until the sealing block 300 is in close contact with the luggage. The sealing block 300 is completely retracted, and the mechanical claw 42 releases the sealing block 300.

[0073] It is understood that the mechanical gripper 42 may be provided with a pressure sensor. When the pressure sensor is triggered, it indicates that the mechanical gripper 42 is pressed down into place, so that it can adapt to luggage of different heights and sizes. After the mechanical gripper 42 releases the seal 300, the seal 300 is transported away with the luggage, completing the entire luggage sealing process.

[0074] Based on the sealing method of the automatic sealing mechanism 100, by setting a first pushing mechanism 20 and a second pushing mechanism 30, and symmetrically setting an upper telescopic member 21 and a lower telescopic member 22, respectively, in conjunction with a manipulator mechanism 40, it is possible to stretch the sealing belt without unlocking it, and gradually tighten the luggage after it is in place, which not only simplifies the action process, but also can form a sealing ring in advance, thereby improving the sealing efficiency; on the other hand, it can be compatible with multiple generations and different types of sealing bands 300, thereby improving adaptability.

[0075] In another embodiment of this application, please refer to Figure 2 The lateral drive structure 10 includes a forward and reverse screw rod 11, a guide rod 12 and a pushing drive assembly 13. The forward and reverse screw rod 11 is arranged horizontally parallel to the guide rod 12. The output end of the pushing drive assembly 13 is connected to the forward and reverse screw rod 11. The first pushing mechanism 20 and the second pushing mechanism 30 are simultaneously arranged on the forward and reverse screw rod 11 and the guide rod 12.

[0076] It is understandable that the push drive assembly 13 may include a motor and a belt, the motor is connected to the belt, and the other end of the belt is connected to the positive and negative screw rods 11. In this way, when the motor rotates, the positive and negative screw rods 11 can be driven to rotate by the belt. When the positive and negative screw rods 11 rotate forward, the first pushing mechanism 20 and the second pushing mechanism 30 move toward each other at the same time. The guide rod 12 is used to improve guidance and improve stability. When the positive and negative screw rods 11 rotate in the opposite direction, the first pushing mechanism 20 and the second pushing mechanism 30 move back to back at the same time. In this way, the synchronous movement of the first pushing mechanism 20 and the second pushing mechanism 30 is achieved, and the problem of accurate positioning of the first pushing mechanism 20 and the second pushing mechanism 30 is solved. In this way, the lower telescopic member 22 can accurately align with the sealing ring position of the sealing block 300 on the mechanical claw 42.

[0077] In another embodiment of this application, please refer to Figure 3 The mechanical claw 42 is connected to a connecting plate 43, one end of which is connected to the second vertical driving structure 41. When the first pushing mechanism 20 contacts the second pushing mechanism 30, the mechanical claw 42 is located in the middle position between the first pushing mechanism 20 and the second pushing mechanism 30.

[0078] It can be understood that the second vertical drive structure 41 can include a motor, a belt and a guide rail. The motor drives the connecting plate 43 to move vertically through the belt, and the guide rail provides guidance. When the first pushing mechanism 20 contacts the second pushing mechanism 30, the connecting plate 43 can directly extend the mechanical claw 42 to the middle position between the first pushing mechanism 20 and the second pushing mechanism 30. In this way, it is only necessary to pre-design the length of the connecting plate 43. When the first pushing mechanism 20 contacts the second pushing mechanism 30, the lateral positioning of the mechanical claw 42 is also completed.

[0079] In another embodiment of this application, please refer to Figure 3A clamp 24 is also provided at the bottom end of the first pushing mechanism 20 and the second pushing mechanism 30, respectively. The clamp 24 is located on the side where the first pushing mechanism 20 and the second pushing mechanism 30 are close to each other. A channel 25 is provided on the clamp 24, and the channel 25 is vertically arranged.

[0080] It is understood that the clamp 24 can be used to clamp the luggage. Thus, in step 8, while the transverse drive structure 10 drives the first pushing mechanism 20 and the second pushing mechanism 30 toward each other, the clamp 24 straightens and secures the luggage. Furthermore, in step 9, the continuous contraction of the sealing tape prevents the luggage from shifting, thereby improving the sealing quality. The clamp 24 is provided with a channel 25 for the sealing tape to pass through. Thus, in step 5, the lower telescopic member 22 can descend to the lowest point of the first pushing mechanism 20 or the second pushing mechanism 30, allowing the sealing tape to be lower than the conveyor surface of the luggage conveyor, ensuring that the luggage can enter the sealing circle formed by the sealing tape, thus achieving the integrated configuration of the pushing mechanism and the clamping and straightening mechanism.

[0081] It is worth mentioning that the straightening mechanism of the traditional sealing mechanism is independently arranged on both sides of the conveyor belt and does not have the function of clamping the luggage. During the contraction of the sealing belt, lighter luggage may be out of position.

[0082] In another embodiment of this application, please refer to Figure 3 Two groups of photoelectric sensors 26 are provided on each fixture 24 . The two groups of photoelectric sensors 26 are spaced apart from each other. The transmitting end and the receiving end of the photoelectric sensor 26 are located on both sides of the channel 25 .

[0083] As will be appreciated, due to the varying shapes and sizes of luggage, and the varying placement angles, it's crucial to both securely clamp the luggage and avoid damage. To this end, each clamp 24 is equipped with two sets of photoelectric sensors 26, spaced one above the other. The upper sensor senses the clamping state of the luggage's upper side, while the lower sensor senses the clamping state of the luggage's lower side. The transmitting and receiving ends of these photoelectric sensors 26 are located on either side of the passage 25. This means that only when the luggage's surface partially blocks the passage 25 in the clamped state will the corresponding photoelectric sensors 26 be blocked. In the unclamped state, including when the luggage is not in contact with the clamp 24 or when it is in contact with the clamp 24 but not clamped, the photoelectric sensors 26 will not transmit signals. Combining these two principles, a determination procedure can be implemented. When the conditions of "no signal from both the upper and lower photoelectric sensors 26 or both the lower and upper photoelectric sensors 26" are met, the luggage is determined to be securely clamped, and the transverse drive structure 10 stops driving the first and second pushing mechanisms 20 and 30. Improved the accuracy of luggage clamping status judgment.

[0084] See also Figures 8 to 11 The present application further provides a sealing device 200, which includes:

[0085] Support frame 01;

[0086] The conveying mechanism 02 includes an input conveying device 021 and an output conveying device 022 , with an accommodating space 023 provided between the input conveying device 021 and the output conveying device 022 ;

[0087] The locking device 03 is provided on the support frame 01 and is used to provide a locking block 300; and

[0088] The automatic sealing mechanism 100 as described above is disposed on the support frame 01 and is located above the accommodating space 023 .

[0089] It can be understood that the input conveyor 021 is used to input luggage. When the middle position of the luggage reaches the accommodating space 023 where the input conveyor 021 and the output conveyor 022 intersect, the input conveyor 021 and the output conveyor 022 stop moving. This can be achieved by providing photoelectric sensors 26 on both sides of the input conveyor 021 and the output conveyor 022.

[0090] The locking device 03 is a loading device that combines storage and transport of the seal block 300. The locking device 03 can be fixed to the support frame 01 to facilitate grasping by the robot mechanism 40. The only difference from traditional industrial loading devices is the loading object. Alternatively, the seal block 300 can be manually placed in the locking device 03, which then transports it to a designated location for grasping by the robot mechanism 40.

[0091] The automatic sealing mechanism 100 can pre-pull the sealing ring, and the sealing ring passes through the accommodating space 023, so that the luggage can enter the sealing ring to complete the sealing action on the luggage.

[0092] After the luggage is sealed, it is transported away through the output transmission device 022.

[0093] Since the sealing device 200 adopts the automatic sealing mechanism 100 as described above, it also has the beneficial effects of the automatic sealing mechanism 100. In addition, the automatic sealing mechanism 100 integrates luggage conveying, automatic locking, and automatic sealing, thereby improving the sealing and locking efficiency.

[0094] In another embodiment of this application, please refer to Figure 9 The lower telescopic member 22 includes a first connecting frame 221, a first electric push rod 222 and a positioning frame 223. The first connecting frame 221 is arranged on the corresponding first pushing mechanism 20 or the second pushing mechanism 30. The first electric push rod 222 is arranged on the first connecting frame 221. The positioning frame 223 is arranged on the output end of the first electric push rod 222. The positioning frame 223 is provided with a bayonet 224 with a larger outer side and a smaller inner side.

[0095] It's understood that an electric push rod, also known as a linear actuator, is a novel linear actuator primarily composed of a motor push rod and a control device. It can be considered a structural extension of a rotary motor. When the first electric push rod 222 extends, it drives the retaining frame 223 to extend. The retaining opening 224 on the retaining frame 223 retains the sealing tape. The retaining opening 224, which is larger on the outside and smaller on the inside, facilitates the retaining frame 223 retaining the sealing tape.

[0096] Further, please also refer to Figure 9The lower telescopic member 22 also includes a first pulley 225 and a first return spring 226. The first pulley 225 is arranged at one end of the first connecting frame 221 away from the first electric push rod 222. One end of the first return spring 226 is connected to the first connecting frame 221, and the other end is connected to the corresponding first pushing mechanism 20 or the second pushing mechanism 30; the first pushing mechanism 20 and the second pushing mechanism 30 are provided with a first guide bracket 227, and the first guide bracket 227 is vertically arranged for contacting the first pulley 225. The first connecting frame 221 is rotatably arranged on the corresponding first pushing mechanism 20 or the second pushing mechanism 30 through a rotating shaft.

[0097] It is understood that based on the above arrangement, in step 5, when the transverse drive structure 10 drives the first pushing mechanism 20 and the second pushing mechanism 30 to move in opposite directions, the first pulley 225 contacts the first guide bracket 227, and the first connecting frame 221 rotates, causing the positioning frame 223 to further stretch the sealing tape, thereby ensuring that the stretched width below the sealing ring is greater than or equal to the width of the conveyor mechanism 02. This can further accommodate luggage of different sizes and positions, ensuring that luggage enters the sealing ring smoothly. The first return spring 226 is used for reset.

[0098] In addition, a first guide bracket 227 is provided on the first pushing mechanism 20 and the second pushing mechanism 30, so as to allow the first guide bracket 215 to be closer to the first connecting frame 221. When the first connecting frame 221 contacts the first guide bracket 227, it quickly rotates to the maximum rotation angle; at the same time, the first connecting frame 221 maintains the maximum rotation angle during the descending process, so as to avoid the collision between the lower telescopic member 22 and the clamp 24. In the state of the maximum rotation angle, the entire first connecting frame 221 is located inside the clamp 24, and the sealing belt can pass through the channel 25, thereby realizing the integrated setting of the lower telescopic member 22 and the clamp 24.

[0099] In another embodiment of this application, please refer to Figure 10 The upper telescopic member 21 includes a second connecting frame 211 and a second electric push rod 212. The second connecting frame 211 is arranged on the corresponding first pushing mechanism 20 or the second pushing mechanism 30, and the second electric push rod 212 is arranged on the second connecting frame 211.

[0100] It can be understood that, since in step 4, when the upper telescopic member 21 on the first pushing mechanism 20 and the second pushing mechanism 30 is extended, the sealing ring has been preliminarily stretched in step 3, so it can be easily inserted through the output end of the second electric push rod 212, and the structure can be simplified relative to the lower telescopic member 22.

[0101] Further, please also refer to Figure 10 The upper telescopic member 21 also includes a second pulley 213 and a second return spring 214. The second pulley 213 is arranged at one end of the second connecting frame 211 away from the second electric push rod 212. One end of the second return spring 214 is connected to the second connecting frame 211, and the other end is connected to the corresponding first pushing mechanism 20 or the second pushing mechanism 30; a second guide bracket 215 is provided on the support frame 01, and the second guide bracket 215 is tilted for contacting the second pulley 213. The second connecting frame 211 is rotatably arranged on the corresponding first pushing mechanism 20 or the second pushing mechanism 30 through a rotating shaft.

[0102] It can be understood that in step 5, when the first vertical driving structure 23 drives the lower telescopic member 22 to move downward, after the second pulley 213 contacts the second guide bracket 215, the second connecting frame 211 will rotate, so that the second electric push rod 212 further stretches the sealing belt, thereby making the stretched width below the sealing ring greater than or equal to the width of the conveying mechanism 02. In this way, it can further adapt to luggage of different sizes and positions and ensure that the luggage enters the sealing ring smoothly.

[0103] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
