Description

Technical Field

[0001] This application belongs to the field of baggage transportation technology, specifically relating to a sealing device for the gaps around an airport baggage weighing conveyor. Background Technology

[0002] The airport baggage system uses weighing conveyors to weigh passenger baggage. These conveyors are installed next to the check-in counters in the terminal. When checking in their baggage, passengers place it on the conveyor. After the electronic scale displays the weight, check-in staff enter the weight into the departure information system, linking it to the passenger's name and the weight of each piece of baggage checked in by that passenger. The staff then affixes a baggage barcode to the baggage and presses the forward button. The baggage is then transported by the conveyor to the baggage system for subsequent security checks, sorting, and loading.

[0003] To ensure accurate weight measurement, the weighing conveyor needs to be kept at least 1 cm away from other civil engineering facilities (such as check-in counters, floors, etc.) to prevent these facilities from pressing against the weighing conveyor and causing the pressure sensor at the bottom of the weighing conveyor to output additional electrical signals, resulting in the electronic scale displaying a baggage weight that is greater or less than the actual weight.

[0004] However, in actual use, passengers' small items such as ID cards, passports, boarding passes, and keys are easily dropped into the gaps between the weighing conveyor and other surrounding civil engineering facilities, making them difficult to retrieve and potentially causing passengers to miss their flights. Utility Model Content

[0005] The purpose of this application is to provide a sealing device for the gaps around an airport baggage weighing conveyor, which can solve the problem of small items falling into the gaps.

[0006] This application provides a sealing device for the gaps around an airport baggage weighing conveyor, disposed between the output end of the weighing conveyor and the receiving component, comprising: a first substrate extending along a first direction; a second substrate disposed at one end of the first substrate and extending along a second direction, the second substrate being fitted to the receiving component on one side of the second direction and to the edge of the output end of the weighing conveyor on the other side of the second direction; and a reinforcing structure disposed at the inner corner of the junction of the first substrate and the second substrate; wherein, both the first substrate and the second substrate are elastic polymer substrates.

[0007] In the above technical solution, the gap sealing device around the airport baggage weighing conveyor can prevent vertical deformation from causing passenger items to fall into the gap, and can also avoid excessive pressure on the front end of the weighing conveyor. Therefore, it can avoid the problem of inaccurate weighing caused by mutual squeezing with the weighing conveyor.

[0008] In some technical solutions, optionally, a thickened portion is provided at the inner corner of the junction of the first substrate and the second substrate to form a reinforced structure. This results in greater strength at the junction of the first substrate and the second substrate, thereby enabling the sealing device to maintain good vertical stiffness and preventing vertical deformation from causing passenger items to fall into the gap.

[0009] In some technical solutions, optionally, the side of the thickened portion away from the inner corner of the junction is a concave arc surface.

[0010] In practical applications, the thickened part adopts an arc transition. The thickness of the first substrate and the second substrate is thicker closer to the junction of the two, and thinner closer to the weighing conveyor. This allows the sealing device and the weighing conveyor to have no contact or only slight contact, avoiding excessive squeezing force on the weighing conveyor and causing inaccurate weighing.

[0011] In some technical solutions, the first substrate, the second substrate, and the thickened portion may optionally be made of the same material.

[0012] In the above technical solution, all components are made of the same material, which can ensure the matching of material properties, reduce the complexity of combining dissimilar materials, and reduce processing difficulty and cost.

[0013] In some technical solutions, the elastic polymer matrix may optionally include a composite rubber matrix.

[0014] In practical applications, the composite rubber matrix allows for flexible cutting and offers quick and easy installation. Furthermore, it can be rolled up for storage and transport before use, saving space, being easy to carry, resistant to drops and impacts, requiring no special protection during transport, and resulting in low logistics costs.

[0015] In some technical solutions, the first substrate, the second substrate, and the thickened portion can optionally be integrally formed. Integral forming can reduce processing difficulty.

[0016] In some technical solutions, the gap sealing device around the airport baggage weighing conveyor may optionally include an adhesive component; wherein the adhesive component is disposed on the side of the first substrate facing away from the second substrate.

[0017] In practical applications, installation is achieved through adhesive bonding, eliminating the need for additional fasteners and thus reducing the difficulty of installation.

[0018] In some technical solutions, the adhesive component optionally includes a first adhesive surface and a second adhesive surface, with the first adhesive surface and a first substrate being bonded together. The adhesive component uses double-sided adhesive, enabling rapid assembly.

[0019] In some technical solutions, the second adhesive surface is optionally covered with a protective film.

[0020] In the above technical solution, the protective film can effectively prevent the second adhesive surface from coming into contact with dust, dirt, moisture and other impurities in the external environment when it is not in use, thereby avoiding contamination and damage to the second adhesive surface and ensuring that the second adhesive surface can maintain good adhesive performance when in use.

[0021] In some technical solutions, the protective film may optionally be a plastic protective film.

[0022] Additional aspects and advantages of the technical solutions of this application will become apparent in the following description or may be learned by practice of this application. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0026] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0027] Airport baggage systems are designed to handle baggage checked in by passengers on commercial aircraft. When passengers check in their baggage, the system weighs the baggage, reads the baggage tag information, and conducts a security check. The baggage is then transported via conveyor belt from the check-in area to the security check area, the sorting and handling area, and finally to the departure carousel. At the departure carousel, ground staff transfer the baggage to baggage trolleys, which are then transported and moved into the aircraft's cargo hold. Large hub airports often have more than 300 weighing conveyors.

[0028] To ensure accurate weight measurement, the weighing conveyor needs to be kept at least 1 cm away from other civil engineering facilities (such as check-in counters, floors, etc.) to prevent these facilities from pressing against the weighing conveyor and causing the pressure sensor at the bottom of the weighing conveyor to output additional electrical signals, resulting in the electronic scale displaying a baggage weight that is greater or less than the actual weight.

[0029] In related technologies, to prevent small items belonging to passengers from falling into the gap between the weighing conveyor and other surrounding civil engineering structures, the following two methods are typically used to fill the gap: (1) Use rigid materials for sealing, such as iron, stainless steel, and various types of stone. These materials can be filled by adhesive bonding, that is, fixed to the existing marble floor with glue, so that there is no gap between the existing floor and the weighing conveyor. Alternatively, they can be fixed by ground support, such as bolting from the ground under the weighing conveyor and installing brackets as support structures, which are fixed between the existing marble floor and the weighing conveyor.

[0030] (2) Use flexible materials for sealing, such as rubber, putty, or brushes. These materials can be filled by adhesive bonding, that is, by fixing them to the existing marble floor with adhesive, so that there is no gap between the existing floor and the weighing conveyor.

[0031] However, in actual use, due to thermal expansion and contraction and structural deformation of the weighing conveyor, if rigid materials are used for sealing, the filling material may squeeze against the conveyor, resulting in inaccurate weighing. On the other hand, if flexible materials are used, such as brushes or rubber, they are not rigid enough and easily bend, still failing to prevent passengers' ID cards, passports, keys, and other items from falling into the gaps.

[0032] In view of this, in order to achieve both limited filling of gaps to prevent passengers' items from falling into the gaps, and to avoid squeezing the weighing conveyor and causing inaccurate baggage weight display on the weighing conveyor, this application aims to provide a gap sealing device around an airport baggage weighing conveyor, including a first substrate, a second substrate, and a reinforcing structure, wherein the reinforcing structure is disposed at the inner corner of the junction of the first substrate and the second substrate; wherein, the first substrate and the second substrate are both elastic polymer substrates. The elastic polymer matrix has reversible deformation properties. It is elastic at room temperature and can produce large deformations under small external forces. After the external force is removed, it can return to its original shape. In this way, when the weighing conveyor experiences thermal expansion and contraction or structural deformation, the flexible deformation of the front end of the first or second matrix can prevent excessive pressure on the front end of the weighing conveyor. This avoids the problem of inaccurate weighing caused by mutual compression between the matrix and the conveyor. At the same time, the reinforced structure can improve the strength at the junction of the first and second matrices, resulting in small deformation at the junction. This allows the sealing device to maintain good vertical stiffness, thereby preventing passenger items from falling into the gap due to vertical deformation.

[0033] The following is combined Figure 1 and Figure 2 The present application provides a detailed description of a sealing device for the gaps around an airport baggage weighing conveyor through specific embodiments and application scenarios.

[0034] Reference Figure 1 The weighing conveyor 200, used for weighing luggage, includes a conveyor 210, a load cell 220, and a support frame 230. The support frame 230 is placed on the ground, serving as a basic load-bearing structure and providing an installation reference for other components. The conveyor 210 is mounted on the support frame 230, forming a luggage transport channel. The load cell 220 is mounted on the support frame 230 and connected to the conveyor 210. When luggage is placed on the conveyor 210, its weight is transmitted to the load cell 220, generating a digital weight value.

[0035] In some embodiments, a traveling device 240 is provided at the bottom of the support frame 230 to facilitate the movement of the weighing conveyor 200. Specifically, the traveling device 240 includes, but is not limited to, casters and tracks.

[0036] In use, since the weighing conveyor 200 is elevated above the ground, a receiving assembly 300 is provided at the output end of the conveyor 210. The receiving assembly 300 includes a support member 310 and a receiving member 320. The support member 310 is located on the ground, and the receiving member 320 is located at the top of the support member 310 and extends towards the output end of the conveyor 210; wherein, a gap 330 is formed between the receiving member 320 and the output end of the conveyor 210.

[0037] The sealing device 100 around the airport baggage weighing conveyor proposed in this application embodiment is set in the gap 330. It can prevent vertical deformation from causing passenger items to fall into the gap, and also avoid excessive pressure on the front end of the weighing conveyor. Therefore, it can avoid the problem of inaccurate weighing caused by mutual squeezing with the weighing conveyor.

[0038] Reference Figure 1 and Figure 2 In some embodiments, the airport baggage weighing conveyor surrounding gap sealing device 100 (hereinafter referred to as sealing device 100) proposed in this application is disposed between the output end of the weighing conveyor 200 and the receiving component 300, and its structure includes: a first base 110, a second base 120 and a reinforcing structure 130.

[0039] Specifically, the first substrate 110 extends along a first direction. A second substrate 120 is disposed at one end of the first substrate 110 and extends along a second direction; the second substrate 120 is attached to the receiving assembly 300 on one side of the second direction, and to the edge of the output end of the weighing conveyor 200 on the other side of the second direction. A reinforcing structure 130 is disposed at the inner corner 140 of the junction of the first substrate 110 and the second substrate 120. Both the first substrate 110 and the second substrate 120 are elastic polymer substrates.

[0040] The elastic polymer matrix has reversible deformation characteristics. It is elastic at room temperature and can produce large deformation under a small external force. After the external force is removed, it can return to its original shape. In this way, when the weighing conveyor 200 undergoes thermal expansion and contraction, structural deformation, etc., the flexible deformation of the front end of the second matrix 120 in the horizontal direction (second direction) can avoid excessive pressure from the sealing device 100 on the output end of the weighing conveyor 200. Thus, it can avoid the problem of inaccurate weighing caused by mutual compression between the sealing device 100 and the weighing conveyor 200. At the same time, the reinforcing structure 130 can improve the strength at the junction of the first matrix 110 and the second matrix 120, so that the deformation at the junction of the first matrix 110 and the second matrix 120 is small. This allows the sealing device 100 to maintain good vertical (first direction) stiffness, thereby preventing passenger items from falling into the gap due to vertical deformation. Furthermore, the first substrate 110 and the second substrate 120 form an "L"-shaped structure, which can increase the contact area between the sealing device 100 and the mounting surface during use, thereby improving the connection stability of the sealing device 100 and achieving stable fixation.

[0041] In some embodiments, the inner corner 140 at the junction of the first substrate 110 and the second substrate 120 is provided with a thickened portion 150 to form a reinforcing structure 130. This results in greater strength at the junction of the first substrate 110 and the second substrate 120, thereby enabling the sealing device 100 to maintain good vertical stiffness and preventing vertical deformation from causing passenger items to fall into the gap.

[0042] It is understood that the reinforcing structure 130 may also be other structures such as partial inserts, ribs and stiffeners, and this embodiment is not limited thereto.

[0043] In the above embodiment, the side of the thickened portion 150 facing away from the inner corner 140 at the junction is a concave arc surface 152, that is, the thickened portion 150 adopts an arc transition. Through the arc transition, the thickness of the first substrate 110 and the second substrate 120 is thicker closer to the junction between them, and thinner closer to the weighing conveyor 200. This allows the sealing device 100 and the weighing conveyor 200 to have no contact or only slight contact, avoiding excessive pressure on the weighing conveyor 200 and causing inaccurate weighing.

[0044] In practical applications, the first substrate 110, the second substrate 120, and the thickened portion 150 are made of the same material. Using the same material for all components ensures matching material properties (strength, coefficient of thermal expansion, corrosion resistance, etc.) and reduces the complexity of combining dissimilar materials, thereby lowering processing difficulty and cost.

[0045] Specifically, the first substrate 110, the second substrate 120, and the thickened portion 150 are integrally formed. It is understood that the thickened portion 150 may also be connected to the first substrate 110 and the second substrate 120 by other means such as bonding.

[0046] In some embodiments, the elastic polymer matrix includes a composite rubber matrix. The composite rubber matrix allows the sealing device 100 to be flexibly cut to fit the heights of the receiving component 320 and the weighing conveyor 200, achieving complete and effective filling of the gap 330, and providing quick and convenient installation. Furthermore, it can be rolled up and transported before use, offering advantages such as space saving, portability, impact and shock resistance, no need for special protection during transportation, and low logistics costs.

[0047] In some embodiments, the sealing device 100 further includes an adhesive member 160. The adhesive member 160 is disposed on the side of the first substrate 110 opposite to the second substrate 120.

[0048] In practical applications, the sealing device 100 is fixed to one side of the receiving part 320 by the adhesive part 160 to fill the gap 330 without the need for additional fasteners, thereby reducing the difficulty of installation.

[0049] In some embodiments, the adhesive 160 includes a first adhesive surface 162 and a second adhesive surface 164, the first adhesive surface 162 being bonded to the first substrate 110, and the second adhesive surface 164 being bonded to the mounting surface of the receiving component 320.

[0050] In the above embodiments, the adhesive 160 uses double-sided adhesive, which enables the rapid assembly of the sealing device 100.

[0051] In practical applications, the second adhesive surface 164 is covered with a protective film 166. The protective film 166 can effectively prevent the second adhesive surface 164 from coming into contact with dust, dirt, moisture and other impurities in the external environment when it is not in use, thereby avoiding contamination and damage to the second adhesive surface 164, and ensuring that the second adhesive surface 164 can maintain good adhesive performance when in use.

[0052] Specifically, protective film 166 is a plastic protective film. It is understandable that it also includes silicone-coated paper, etc.

[0053] The following is a practical verification of the effectiveness of the sealing device 100 provided in this application by comparing the data of passenger items falling into the gaps at the check-in counter under different passenger volume conditions, and the impact of different types of gap filling seals on the deviation of the weight measurement of the weighing conveyor after 100 days of use.

[0054] Table 1: Number of reports of passenger belongings falling into gaps under the same passenger volume

[0055] As shown in Table 1, under the same passenger volume, the sealing device 100 of this application reduces the probability of passenger items falling into gaps by more than 94%. Compared with seals using flexible filling materials, the sealing device 100 of this application reduces the probability of passenger items falling into gaps by more than 91%. Compared with seals using rigid filling materials, the sealing device 100 of this application reduces the probability of passenger items falling into gaps by essentially the same amount.

[0056] Table 2: Number of Repair Reports (Reports) Regarding Weight Measurement Deviation of Weighing Conveyors under the Same Passenger Volume

[0057] As can be seen from Table 2, under the same passenger volume, the rate of measurement deviation of the weighing conveyor 200 caused by the use of the sealing device 100 of this application is basically the same as that before any filling seal is installed, and is significantly lower than the rate of measurement deviation of the weighing conveyor after filling with a seal made of rigid material, and is basically the same as that of the seal made of flexible material.

[0058] Therefore, the sealing device 100 provided in this application can effectively prevent passenger items from falling into the gap and avoid adverse effects on the measurement accuracy of the weighing conveyor 200.
