Description

Technical Field

[0001] This application relates to the field of security inspection equipment technology, and in particular to a conveyor straightening device and an automatic sealing system. Background Technology

[0002] When checking in baggage, suspicious baggage needs to be marked with a seal. Common methods for marking suspicious baggage include manually attaching an electronic security lock to the baggage or using an automatic sealing device to apply a security strap to the baggage.

[0003] Automated baggage sealing devices have certain requirements regarding the orientation of suspicious baggage when sealing it. The long side of the suspicious baggage must be perpendicular to or parallel to its direction of travel. If the suspicious baggage passes by the automated baggage sealing device in an orientation other than these two, the success rate of sealing the baggage will be affected.

[0049] like Figure 1 As shown, this application embodiment provides a conveying object straightening device. The conveying object straightening device mainly includes a conveying section 91 and a straightening section.

[0050] like Figure 1 As shown, the conveying unit 91 includes a first conveying surface 91A, which is used to convey the conveyed object along a first conveying direction. The conveying unit 91 can be a belt conveyor.

[0051] like Figure 1As shown, the straightening part includes a first clamping mechanism 92 and a second clamping mechanism 93 disposed above the first conveying surface 91A and extending along the first conveying direction. The first clamping mechanism 92 and the second clamping mechanism 93 are arranged at intervals in a direction perpendicular to the first conveying direction and the intervals are adjustable. The side of the first clamping mechanism 92 facing the second clamping mechanism 93 includes a first movable part 921 that moves along the first conveying direction or in the opposite direction of the first conveying direction, and / or the side of the second clamping mechanism 93 facing the first clamping mechanism 93 includes a second movable part 931 that moves along the first conveying direction or in the opposite direction of the first conveying direction.

[0052] Based on the conveyor straightening device provided in this application, the conveyor straightening device straightens the conveyed object through the movable parts of two adjustable-pitch clamping mechanisms. It has a simple structure and a high success rate in straightening the conveyed object.

[0053] like Figure 1 As shown, the second aspect of this disclosure provides an automatic sealing system, including a conveyor alignment device 9 and an automatic sealing device according to the first aspect of this disclosure.

[0054] The automatic sealing device is located downstream of the conveyor straightening device 9 and is configured to seal and mark the conveyed items transported by the conveyor straightening device.

[0055] like Figures 1 to 13 As shown, in some embodiments of the automatic sealing system, the automatic sealing equipment mainly includes a lock feeding device 1, a conveying device 5, and a sealing device 2.

[0056] The lock delivery device 1 is configured to deliver the electronic supervision lock 3 to the lock delivery position 13A of the lock delivery device 1. The conveying device 5 is located downstream of the conveying section 91 and is used to receive the conveyed item, including a second conveying surface 5A that conveys the conveyed item along a second conveying direction. The sealing device 2 is configured to pass the supervision belt 4 through the locking ring 31 of the electronic supervision lock 3 located at the lock delivery position 13A of the lock delivery device 1 and secure it to the conveyed item.

[0057] The automatic sealing system of this application uses the conveyor alignment device of this application, which results in a higher sealing success rate.

[0058] The following combination Figures 1 to 13 The conveyor alignment device 9 and the automatic sealing system according to embodiments of the present disclosure will be described in more detail.

[0059] like Figure 1 As shown, in some embodiments of the conveyor straightening device 9, the first clamping mechanism 92 includes a first movable part 921, and the second clamping mechanism 93 includes a second movable part 931. The first movable part 921 and the second movable part 931 move in opposite directions.

[0060] The opposite movement directions of the first movable part 921 and the second movable part 931 facilitate the simultaneous application of a force to the conveyed object to straighten it, thereby increasing the straightening speed of the conveyed object.

[0061] like Figure 1 As shown, in some embodiments of the conveyor alignment device 9, the first clamping mechanism 92 includes a first conveyor, and the first movable part 921 includes the conveying surface of the first conveyor; and / or the second clamping mechanism 93 includes a second conveyor, and the second movable part 931 includes the conveying surface of the second conveyor.

[0062] The first clamping mechanism 92 and / or the second clamping mechanism 93 are implemented by means of a conveyor, which can be realized without special design.

[0063] like Figure 1 As shown, in some embodiments of the conveyor alignment device 9, at least one of the first conveyor and the second conveyor is a belt conveyor. The conveying surface of the belt conveyor is flat and without perforations, allowing for good contact with the conveyed object and facilitating faster and better adjustment of the object's posture.

[0064] like Figure 1 As shown, in some embodiments of the conveyor alignment device 9, the conveyor alignment device 9 further includes a clamping mechanism drive unit 94, which is drivenly connected to at least one of the first clamping mechanism 92 and the second clamping mechanism 93 to adjust the interval between the first clamping mechanism 92 and the second clamping mechanism 93. Providing the clamping mechanism drive unit 94 facilitates the automatic adjustment of the conveyor's posture.

[0065] like Figure 1 As shown, in some embodiments of the conveyor straightening device 9, the clamping mechanism drive unit 94 includes a first actuation unit 941 drivenly connected to the first clamping mechanism 92 and a second actuation unit 942 drivenly connected to the second clamping mechanism 93. Providing the first actuation unit 941 and the second actuation unit 942 facilitates increasing the speed of conveyor straightening.

[0066] like Figure 1 As shown, in some embodiments of the conveyor straightening device 9, the clamping mechanism drive unit 94 drives the first clamping mechanism 92 and the second clamping mechanism 93 to move synchronously toward each other or synchronously away from each other. The synchronous movement of the first clamping mechanism 92 and the second clamping mechanism 93 facilitates rapid straightening of the conveyed object and ensures that the conveyed object is positioned at the center of the first conveying surface 91A in a direction perpendicular to the first conveying direction. This facilitates subsequent automatic sealing by the sealing equipment, improving the sealing success rate.

[0067] like Figure 1As shown, in some embodiments of the conveyor alignment device 9, the conveyor alignment device 9 further includes a mounting frame 95. The mounting frame 95 includes columns 951 disposed on both sides of the conveying section 91 and a crossbeam 952 disposed above the conveying section 91 and connected to the columns 951. A first clamping mechanism 92 and a second clamping mechanism 93 are mounted on the crossbeam 952. A clamping mechanism driving unit 94 drives the first clamping mechanism 92 and / or the second clamping mechanism 93 to move along the crossbeam 952.

[0068] The installation frame 95 is set up so that the first clamping mechanism 92 and / or the second clamping mechanism 93 can move along the crossbeam 952, which is conducive to the installation of the straightening part and also to the accurate movement path of the first clamping mechanism 92 and / or the second clamping mechanism 93, thereby improving the success rate of straightening the conveyed object.

[0069] like Figure 1 As shown, in some embodiments of the conveyor alignment device 9, the conveyor alignment device 9 further includes a conveyor detection sensor, which is configured to detect whether a conveyor is being conveyed on the first conveying surface 91A. The alignment unit performs alignment operations of the first clamping mechanism 92 and the second clamping mechanism 93 based on the detection information of the conveyor detection sensor; and / or the conveying unit 91 starts or stops based on the detection information.

[0070] For example, the conveying object detection sensor is signal-connected to the clamping mechanism drive unit 94, and the clamping mechanism drive unit 94 operates according to the detection information from the conveying object detection sensor. Additionally, the conveying unit 91 and the first clamping mechanism 92 and second clamping mechanism 93 can all be signal-connected to the conveying object detection sensor and operate according to the detection information from the sensor. For example, when the conveying object detection sensor detects a conveying object on the first conveying surface 91A, the conveying unit 91 stops operating, and the first clamping mechanism 92 and second clamping mechanism 93 begin performing a straightening operation. After the conveying object is straightened, the conveying unit 91 continues to convey the object.

[0071] Sensors for detecting conveyed objects include, for example, photoelectric sensors and laser sensors.

[0072] In some embodiments of the conveyor alignment device 9, the conveyor detection sensor includes two sets of photoelectric sensors, which are respectively disposed at the upstream and downstream ends of the first clamping mechanism 92 and the second clamping mechanism 93 along the first conveying direction. This arrangement can detect when the conveyor enters and leaves the operating range of the alignment unit, thereby facilitating the alignment unit to perform effective alignment operations on the conveyor.

[0073] The conveyor straightening device 9 also includes a first support base 96, on which the conveying part 91, the straightening part 92, the mounting frame 95, etc. are all mounted. This arrangement facilitates the overall movement of the conveyor straightening device 9.

[0074] like Figures 1 to 3 As shown, the automatic sealing device also includes a second support base 6 and a cover 7. The locking device 1, the conveying device 5, and the sealing device 2 are mounted on the second support base 6. The cover 7 covers the locking device 1, the conveying device 5, and the sealing device 2. The second support base 6 facilitates the overall movement of the automatic sealing device. The cover 7 provides overall protection for the automatic sealing device.

[0075] like Figures 3 to 13 As shown, the lock feeding device 1 of the automatic sealing equipment in this application embodiment mainly includes a lock chamber 12, a lock feeding platform 13 and a lock feeding mechanism 14.

[0076] The lock cylinder 12 includes a lock body receiving space 12A for accommodating the electronic monitoring lock 3, and the bottom of the lock cylinder 12 includes a lock cylinder outlet 12B communicating with the lock body receiving space 12A for outputting the electronic monitoring lock 3. The lock body receiving space 12A is enclosed by the lock cylinder shell of the lock cylinder 12.

[0077] The lock delivery platform 13 is located below the lock cylinder 12 and has a lock delivery position 13A and a lock dropping position 13B. The lock delivery position 13A is located outside the lock cylinder 12, and the lock dropping position 13B is located below the lock cylinder outlet 12B and is spaced apart from the lock cylinder outlet 12B.

[0078] The lock feeding mechanism 14 includes a lock feeding section 141. The lock feeding section 141 is movably disposed on the lock feeding platform 13 and has a first lock feeding working position and a second lock feeding working position on the lock feeding platform 13. The lock feeding section 141 is configured to: when switching from the first lock feeding working position to the second lock feeding working position, transport the electronic monitoring lock 3 located between the locking position 13B and the lock cylinder outlet 12B to the lock feeding position 13A; when switching from the second lock feeding working position to the first lock feeding working position, the lock feeding section 141 at least partially avoids the space below the lock cylinder outlet 12B so that the electronic monitoring lock 3 output from the lock cylinder outlet 12B falls between the lock cylinder outlet 12B and the locking position 13B.

[0079] The lock delivery device provided in this application embodiment can output an electronic supervision lock from the lock chamber and deliver it to a designated location. This lock delivery device, in conjunction with other parts of the automatic sealing equipment, can bind the electronic supervision lock and the supervision belt to the transported object, achieving sealing and marking of the transported object using a separate supervision belt and electronic supervision lock structure.

[0080] The conveying device 5 includes a second conveying surface 5A for conveying the conveyed object along a second conveying direction. The conveying device 5 is, for example, a belt conveyor, and the second conveying surface 5A is the upper surface of the belt conveyor. The second conveying direction is, for example,... Figure 10 The direction from the inside to the outside of the paper. For example, suspicious luggage.

[0081] The sealing device 2 is configured to pass the supervision belt 4 through the locking ring 31 of the electronic supervision lock 3 located at the locking position 13A of the locking device and bind it to the conveyed object.

[0082] The automatic sealing device of this application embodiment, through the cooperation of a conveying device, a locking device, and a sealing device, can realize the automatic sealing and marking of the conveyed items using a separate structure of a monitoring belt and an electronic monitoring lock.

[0083] like Figures 3 to 8 As shown, the lock feeding device 1 includes the aforementioned lock chamber 12, the aforementioned lock feeding platform 13, and the aforementioned lock feeding mechanism 14.

[0084] like Figures 3 to 8 As shown, in some embodiments of the lock feeding device, the lock feeding mechanism 14 further includes a guide portion 143, and the lock feeding portion 141 reciprocates between a first lock feeding working position and a second lock feeding working position under the guidance of the guide portion 143.

[0085] like Figures 3 to 8 As shown, in some embodiments of the lock feeding device, the guide portion 143 includes a track 1431 and a track mating portion. The track 1431 is disposed on the lock feeding platform 13. The track mating portion is disposed on the lock feeding portion 141 and includes a sliding portion that slides with the track 1431 and / or a rolling portion that rolls with the track 1431. In this embodiment, the track 1431 is a linear slide rail, and the track mating portion includes a groove disposed on the lock feeding portion 141 that slides with the track 1431.

[0086] like Figures 3 to 8 As shown, in some embodiments of the lock feeding device, the lock feeding mechanism 14 includes a first driving part 142, which is drivenly connected to the lock feeding part 141 so that the lock feeding part 141 switches between a first lock feeding working position and a second lock feeding working position.

[0087] like Figures 3 to 8 As shown, in some embodiments of the lock feeding device, the lock feeding mechanism 14 further includes a transmission part 144, and the first driving part 142 is drivenly connected to the lock feeding part 141 through the transmission part 144.

[0088] In some embodiments of the lock feeding device, the first drive unit 142 includes a rotary drive; the lock feeding unit 141 reciprocates linearly relative to the lock feeding platform 13; and the transmission unit 144 is configured to convert the rotary motion of the rotary drive unit into the reciprocating linear motion of the lock feeding platform 13. The transmission unit 144 may, for example, include a lead screw and nut transmission mechanism, a worm gear transmission mechanism, a gear and rack transmission mechanism, or a linkage transmission mechanism.

[0089] like Figure 6As shown, in some embodiments, the first drive unit 142 is a rotary motor. The transmission unit 144 may include, for example, a lead screw and nut transmission mechanism. The lead screw and nut transmission mechanism includes a lead screw 1441 and a nut 1442. The lead screw 1441 is connected to the output shaft of the rotary motor to rotate under the drive of the rotary motor. The nut 1442 is threadedly engaged with the lead screw 1441, and when the lead screw 1441 rotates, the nut 1442 can move along the extension direction of the lead screw 1441. The locking part 141 is fixedly connected to the nut 1442, so that the movement of the nut 1442 can drive the locking part 141 to translate.

[0090] In embodiments not shown, the first drive unit 142 can be a linear drive mechanism, such as an electric cylinder, pneumatic cylinder, or hydraulic cylinder. The linear drive mechanism can directly drive the locking unit 141 to reciprocate linearly.

[0091] like Figures 3 to 8 As shown, in some embodiments of the lock feeding device, the lock feeding part 141 includes a pushing element 1411. In the first lock feeding working position, the pushing element 1411 avoids the locking position 13B, and in the second lock feeding working position, the pushing element 1411 is in the locking position 13B. Figures 3 to 8 As shown, the push element 1411 is cubic in shape. The push element 1411 can be a block structure or a shell structure.

[0092] like Figures 3 to 8 As shown, in some embodiments of the lock feeding device, the lock feeding section 141 further includes a receiving element 1412. The receiving element 1412 is connected to the side of the pushing element 1411 near the lock feeding position 13A, and includes a receiving surface 1412A with a height lower than that of the pushing element 1411.

In the second lock feeding working position, the receiving element 1412 is located in the lock feeding position 13A to convey the electronic supervision lock 3 it has received to the lock feeding position 13A. The placement of the receiving element 1412 facilitates the accurate delivery of the electronic supervision lock 3 to the lock feeding position 13A.

[0093] like Figures 3 to 8 As shown, in some embodiments of the lock feeding device, the receiving element 1412 includes a receiving portion 14121 and a limiting portion 14122. The receiving portion 14121 includes a receiving surface 1412A. The limiting portion 14122 is disposed on the outside of the receiving portion 14121 and is configured to prevent the electronic supervision lock 3 from moving on the receiving surface 1412A in a direction perpendicular to the moving direction of the lock feeding portion 141. The provision of the receiving portion 14121 and the limiting portion 14122 further facilitates the accurate feeding of the electronic supervision lock 3 to the lock feeding position 13A.

[0094] like Figures 3 to 8As shown, in some embodiments of the lock feeding device, the limiting part 14122 has a guide slope 1412C on the side facing the receiving surface 1412A to guide the electronic supervision lock 3 into the receiving surface 1412A. The guide slope 1412C slopes from top to bottom towards the receiving surface 1412A. The guide slope 1412C facilitates the smooth entry of the electronic supervision lock 3 into the receiving surface 1412A and further facilitates the accurate delivery of the electronic supervision lock 3 to the lock feeding position 13A.

[0095] like Figures 3 to 8 As shown, in some embodiments of the lock feeding device, the receiving element 1412 includes a notch 1412B; the lock feeding platform includes a lock receiving boss 131 disposed at the lock feeding position 13A. In the second lock feeding working position, the notch 1412B of the lock receiving part 131 is shaped to match the lock receiving boss 131, and the height of the receiving surface 1412A is flush with the height of the lock receiving part 131. The notch 1412B and the lock receiving boss 131 cooperate to further facilitate the accurate delivery of the electronic supervision lock 3 to the lock feeding position 13A.

[0096] Figures 3 to 8 In the embodiment shown, the receiving part 14121 includes two spaced-apart strips, with the gap between the two strips forming a notch 1412B.

[0097] like Figure 3 and Figure 4 As shown, in some embodiments of the lock feeding device, the lock feeding device further includes an upper cover 15. The upper cover 15 is disposed on the lock feeding platform 13 and forms a lock feeding mechanism receiving space with the lock feeding platform 13.

The locking ring 31 is located on the outside of the lock housing 32, forming a ring with the lock housing 32, through which the monitoring belt 4 passes. The electronic chip 33 is located inside the lock housing 32 and is used to track and locate the transported item. The electronic chip 33 includes, for example, a UWB (Ultra Wide Band) chip and / or an RFID (Radio Frequency Identification) chip.

[0104] The frame 21 includes a frame body 211 disposed around the second conveying surface. The frame body 211 has a groove 21A disposed along the frame 21 and a slot 21B for the locking ring 31 of the electronic monitoring lock 3 to enter the groove 21A. The locking ring 31 of the electronic monitoring lock 3, which is in the lock delivery position 13A, is outside the slot 21B of the groove 21A.

[0105] The mechanism 25 is configured to convey the monitoring belt 4 along the groove 21A and insert the locking ring 31 of the electronic monitoring lock 3 at the groove opening 21B, so that the monitoring belt 4 is tightened after wrapping around the conveyed object on the second conveying surface 5A and is bound to the conveyed object.

[0106] When the mechanism 25 conveys the monitoring belt 4 along the belt groove 21A, and passes through the electronic monitoring lock 3 in the locking position 13A, the monitoring belt 4 enters the locking ring 31 of the electronic monitoring lock 3. When the monitoring belt 4 is bound to the conveyed object, the electronic monitoring lock 3 is bound to the conveyed object as well, thereby realizing the positioning and tracking of the conveyed object.

[0107] In addition, the sealing device 2 also includes a tape storage box 22. The tape storage box 22 can be used to store the supervision tape 4 that has been pulled out from the tape reel 23.

[0108] like Figure 11 As shown, the mechanism 25 includes a feed roller 251, a mechanism cutter 252, a mechanism heat-sealing plate 253, and a mechanism top plate 254. The feed roller 251 is used to feed the monitoring belt 4 into the belt groove and to tighten the monitoring belt 4. The mechanism cutter 252 is used to cut the monitoring belt 4 after it has been tightened. The mechanism heat-sealing plate 253 is used to connect the two ends of the monitoring belt 4 after it has been tightened, so as to bind the monitoring belt to the conveyor.

[0109] like Figure 3 and Figures 10 to 13As shown, in some embodiments of the automatic sealing device, the frame 21 further includes a movable base plate 212 movably disposed on the frame body 211 and located at the slot 21B. The movable base plate 212 has a first base plate working position and a second base plate working position. In the first base plate working position, the movable base plate 212 passes through the locking ring 31 of the electronic supervision lock 3 and closes the slot 21B to guide the supervision belt 4 through the locking ring 31. In the second base plate working position, the movable base plate 212 avoids the slot 21B so that the locking ring 31 enters the slot 21B.

[0110] The active base plate 212 facilitates the smooth insertion of the monitoring belt 4 into the locking ring 31, and helps prevent individual transported items from being missed by the electronic monitoring lock 3.

[0111] In some embodiments of the automatic sealing device, the movable base plate 212 is rotatably disposed relative to the frame body 211; and / or the movable base plate 212 is translationally disposed relative to the frame body 211. Figures 3 to 13 In the embodiment shown, the movable base plate 212 is translatably disposed relative to the frame body 211.

[0112] In some embodiments of the automatic sealing device, the automatic sealing device further includes a second drive unit, which is drivenly connected to the movable base plate 212 to drive the movable base plate 212 to switch between a first base plate working position and a second base plate working position.

[0113] like Figure 13 As shown, the frame 21 also includes a pressure plate 213 and a pressure plate reset mechanism. The pressure plate 213 is rotatably disposed relative to the frame body 211. The pressure plate 213 includes a first pressure plate working position that at least partially closes the groove 21A and a second pressure plate working position that avoids the groove 21A. The pressure plate reset mechanism applies a force to the pressure plate 213 to tend to place it in the first pressure plate working position. The pressure plate reset mechanism includes, for example, a spring (not shown) connected between the frame body 211 and the pressure plate 213. In this embodiment, as... Figure 13 As shown, the pressure plate 213 is rotatably connected to the frame body 21 via the connecting shaft 214.

[0114] In some embodiments of the automatic sealing device, the conveying device 5 includes a first conveying section 51 and a second conveying section 52 spaced apart along a second conveying direction. A frame 21 is disposed at the interval between the first conveying section 51 and the second conveying section 52, and a mechanism 25 is disposed below the frame 21. This arrangement facilitates the passage of the supervision belt 4 below the second conveying surface 5A through the interval between the first conveying section 51 and the second conveying section 52, thereby facilitating the tightening and binding of the supervision belt 4.

[0115] The following describes the working process of the conveyor alignment device and automatic sealing system according to the embodiments of this application.

[0116] The conveyor alignment device 9 is located upstream of the automatic sealing equipment and is used to align the conveyor to be sealed. The conveyor may be, for example, suspicious luggage to be sealed.

[0117] The first clamping mechanism 92 and the second clamping mechanism 93 of the conveyor straightening device 9 are both belt conveyors. The two belt conveyors are located on both sides of its conveying section 91. The conveyor belts of the two belt conveyors run in opposite directions, which helps to ensure that the conveyor with the diagonal perpendicular to the running direction can contact the conveyor belts of the belt conveyors on both sides, so that the angle can be adjusted by the conveyor belts and finally straightened.

[0118] Two belt conveyors each have a set of photoelectric sensors installed at their inlet side (upstream end along the first conveying direction) and outlet side (downstream end along the first conveying direction) as conveyed object detection sensors. Preferably, the conveyor belt length is not shorter than the distance between the two sets of photoelectric sensors. The set of photoelectric sensors located at the conveyor belt inlet side can detect when the conveyed object enters the operating range of the straightening section. At this time, the conveying section 91 pauses, and the straightening section performs a straightening operation on the conveyed object, including adjusting the interval between the first clamping part 92 and the second clamping part 93 so that at least one of the first clamping part 92 and the second clamping part 93 contacts the conveying section, causing the first movable part 921 and the second movable part 931 to move and adjust the posture of the conveyed object on the first conveying surface 91A. The set of photoelectric sensors located at the conveyor belt outlet side can detect when the conveyed object leaves the operating range of the straightening section. At this time, the straightening operation for the next conveyed object can begin.

[0119] After the conveyed item is aligned by the conveyed item alignment device 9, the conveying unit 91 operates, conveying the aligned conveyed item to the conveying device 5 of the downstream automatic sealing equipment. The conveyed item is delivered by the conveying device 5 to the space formed by the frame 21 of the sealing device 2 and the second conveying surface 5A. At the same time, the lock delivery device 1 operates, and the rotary motor of the first drive unit 142 rotates. The lock delivery unit 141 switches from the first lock delivery working position to the second lock delivery working position, delivering the electronic monitoring lock 3 between the locking position 13B and the lock magazine outlet 12B to the lock delivery position 13A.

[0120] The locking ring 31 of the electronic supervision lock 3 entering the locking position 13A needs to enter the slot 21B of the frame 21. The movable base plate 212 needs to rotate to the second base plate working position to avoid the locking ring 31. When the electronic supervision lock 3 enters the locking position 13A, the locking ring 31 enters the slot 21B. The hollow part of the locking ring 31 is located below the movable base plate 212. The lock body detection sensor 16 detects the presence of the electronic supervision lock 3 in the locking position 13A. The second drive unit, which is driven by the movable base plate 212, is activated, causing the movable base plate 212 to rotate, switching from the second base plate working position to the first base plate working position. The locking ring 31 is inserted and the slot 21B is closed, making the slot 21A continuous. Thus, the movable base plate 212 can guide the supervision belt 4 to enter the locking ring 31, while preventing the supervision belt 4 from entering the slot 21B. This can prevent the electronic supervision lock 3 from being missed during sealing.

[0121] The feed roller 251 of the mechanism 25 of the sealing device 2 rotates in the forward direction, causing the supervision belt 4 to run one revolution along the groove 21A of the frame 21, and pass through the locking ring 31 of the electronic supervision lock 3 in the locking position 13A at the groove 21B, reaching the position of the top plate 254 of the mechanism, triggering the top plate position sensor on the top plate 254 of the mechanism. After the top plate position sensor is triggered, the rotary motor of the second drive unit rotates in the reverse direction, driving the movable base plate 212 to rotate, switching from the second locking working position to the first locking working position, and disengaging from the locking ring 31 of the electronic supervision lock 3.

[0122] The rotary motor of the lock feeding device 1, which serves as the first drive unit 142, rotates, and the lock feeding unit 141 switches from the second lock feeding working position to the first lock feeding working position. The electronic supervision lock 3 at the bottom of the lock cylinder outlet 12B falls onto the receiving surface 1412A of the receiving part 14121 located at the locking position 13B under the action of gravity. At the same time, the belt feeding wheel 251 of the mechanism 25 rotates in the opposite direction to tighten the supervision belt 4. At this time, the belt tension is greater than the force applied to the pressure plate 213 by the pressure plate reset device to keep it in the first pressure plate working position. The pressure plate 213 rotates around the connecting shaft 214 to switch to the second pressure plate working position, causing the supervision belt 4 to disengage from the belt groove 21A. The supervision belt 4, together with the electronic supervision lock 3 on the supervision belt 4, seals the suspicious baggage. After the supervision belt 4 disengages from the belt groove 21A, the pressure plate 213 switches from the second pressure plate working position to the first pressure plate working position under the action of the pressure plate reset device. The mechanism's heat-sealing plate 253 moves upward, bonding and fusing the joints of the monitoring belt 4. Simultaneously, the mechanism's cutting blade 252 moves upward, cutting the monitoring belt 4, thus completing the sealing and binding of the suspicious baggage. The conveyor device 5 operates, sending the sealed suspicious baggage out of the sealing device 2, completing the automatic sealing of the baggage.

[0123] In this embodiment, the electronic monitoring lock body and the monitoring belt are independent of each other. The monitoring belt is a consumable material, such as PP packaging belt used for ordinary packaging. The electronic monitoring lock can be reused.

[0124] As can be seen from the above description, the conveyor alignment device and automatic sealing system of the present application embodiments have at least one of the following advantages:

[0125] This device can automatically align and seal transported items, achieving a high success rate in both alignment and sealing. Testing has shown that the alignment success rate of the transported items alignment device in this embodiment reaches over 95% for various types of bags and cases.

[0126] The automatic sealing system boasts high flexibility, allowing it to work with various positioning and tracking systems to locate and track the delivered items without requiring configuration changes. For example, by selecting different electronic monitoring locks, it can be used with video surveillance positioning systems or UWB positioning systems, without altering the configuration of the automatic sealing equipment itself.

[0127] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application and not to limit them; although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this application or equivalent substitutions can be made to some technical features, all of which should be covered within the scope of the technical solutions claimed in this application.
