Description

Technical Field

[0001] The utility model relates to the technical field of luggage carousels, in particular to an airbag type buffer device. Background Art

[0002] In existing baggage handling systems, some areas utilize inclined baggage carousels for baggage conveyance. However, as baggage is loaded onto the inclined carousels, a belt conveyor typically tosses it from the upper end of the inclined carousel at a certain initial velocity. This causes the baggage to glide from the upper end to the lower end of the inclined carousel under the influence of the initial velocity and gravity. When the initial velocity is high or the baggage is heavy, the kinetic energy generated by the baggage is high. This high kinetic energy can cause the baggage to collide with the inclined conveyor equipment, causing significant impact and damage to the baggage. This can also generate significant noise, significantly reducing the passenger experience.

[0003] Chinese utility model patent publication number CN219990199U discloses a buffer device for conveying articles, which includes an inclined conveyor and an article feeder located at a high position of the inclined conveyor. It is characterized in that a buffer assembly is provided on the outer side of the lower position of the inclined conveyor, and the buffer assembly is connected to a swing arm assembly on the back of the buffer assembly. The swing arm assembly is mounted on a bracket and connected to a power assembly.

[0004] The aforementioned article conveying buffer device, before the articles delivered by the article feeder enter the inclined conveyor, uses a power assembly to drive the swing arm assembly, which then extends the buffer assembly. This means the buffer assembly extends and arrives in place ahead of time. The cushioning pad's flexibility and active absorption of the article's kinetic energy prevents the article from colliding with the lower level of the inclined conveyor, reducing impact force and noise. It also forms a linkage control with the upstream conveying system and its controller, and does not occupy the conveyor equipment's working space, allowing it to avoid other articles on the conveyor equipment. However, the material selection for the front-contact parts of the luggage presents a dilemma: balancing wear resistance and flexibility. Furthermore, each device essentially requires a power source, which prevents it from achieving superior energy-saving and environmental benefits. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide an airbag-type buffer device, which takes into account both wear resistance and flexible collision. By controlling the deformation of the expansion part, the airbag buffer device can flexibly receive the luggage and reduce the luggage damage rate. It can also use only one power source to match multiple sets of buffer mechanisms, which is energy-saving and environmentally friendly.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

The cushioning mechanism is provided with an expansion portion. When the cushioning mechanism is inflated, the expansion portion extends into the lower end surface of the inclined luggage carousel. When the cushioning mechanism is in a normal state, the expansion portion is located outside the lower end surface of the inclined luggage carousel. The cushioning mechanism is connected to the pressure detection device. The luggage detection device is used to detect luggage passing through the lower end surface of the inclined luggage carousel.

[0008] Furthermore, the buffer mechanism is a hollow container that can store compressed air, and can be deformed as the pressure in the hollow container changes.

[0027] Example 1:

[0028] like Figures 1-4As shown, this embodiment provides an airbag-type cushioning device, which includes a cushioning mechanism 1, a luggage detection device 2, and a pressure detection device 3. The cushioning mechanism 1 is connected to an external air source device and is mounted on a force-bearing surface corresponding to the lower end surface of the inclined luggage carousel. The cushioning mechanism 1 is provided with an expansion portion. When the cushioning mechanism 1 is inflated, the expansion portion extends into the lower end surface of the inclined luggage carousel. When the cushioning mechanism 1 is in a normal state, the expansion portion is located outside the lower end surface of the inclined luggage carousel. The cushioning mechanism 1 is connected to the pressure detection device 3. The luggage detection device 2 is used to detect luggage passing through the lower end surface of the inclined luggage carousel. In actual use, the buffer mechanism 1 is in its original state, located outside the lower end surface of the inclined luggage carousel, and does not interfere with the luggage in operation inside the lower end surface of the inclined luggage carousel. The luggage detection device 2 monitors the luggage injected into the lower end surface of the inclined luggage carousel. When luggage is injected, the luggage detection device 2 detects the luggage, and the air source device is turned on to input compressed air into the buffer mechanism 1. As the pressure in the buffer mechanism 1 increases, the expansion part of the buffer mechanism 1 produces extension deformation, and the pressure detection device 3 monitors the pressure in the buffer mechanism 1. When the pressure reaches the set value, the air source device no longer inputs compressed air into the buffer mechanism 1. At this time, the buffer mechanism The expansion portion of the buffer mechanism 1 extends into the lower end surface of the inclined luggage carousel and contacts the injected luggage. Under the action of air pressure, the expansion portion of the buffer mechanism 1 has a certain elasticity, so that the process of blocking the luggage is a flexible contact, which can prevent the luggage from suffering destructive impact and absorb the kinetic energy of the thrown luggage, thereby slowing it down. After the luggage passes through, the controller controls the output of compressed air in the buffer mechanism 1 to reduce the pressure within the buffer mechanism 1. The pressure detection device 3 monitors the pressure within the buffer mechanism 1. When the pressure reaches the set value, the expansion portion of the buffer mechanism 1 contracts to its original state as the pressure decreases, so as not to interfere with the luggage in the inclined luggage carousel.

[0029] In this embodiment, the cushioning mechanism 1 is a hollow container capable of storing compressed air and deforming in response to changes in pressure within the container. In actual use, when the cushioning mechanism 1 is needed to protect luggage, it increases internal pressure, causing it to expand and protect the luggage. When the cushioning mechanism 1 is no longer needed to protect the luggage, it reduces internal pressure and returns to its normal state.

[0030] In this embodiment, the buffer mechanism 1 includes a cavity 4, a sealing ring 5, an airbag membrane assembly 6, and a pressure plate 7. The sealing ring 5 is disposed between the cavity 4 and the airbag membrane assembly 6. The airbag membrane assembly 6 is fixedly connected to the cavity 4 via the pressure plate 7. The airbag membrane assembly 6 is in communication with the pressure detection device 3. In actual use, the sealing ring 5 is used to strengthen the sealing effect between the airbag membrane assembly 6 and the cavity 4, and the pressure plate 7 is used to secure the airbag membrane assembly 6 to the cavity 4. The airbag membrane assembly 6 is an expansion portion with telescopic expansion function.

[0031] In this embodiment, the airbag membrane assembly 6 includes an inner compression airbag 61 and an outer wear-resistant airbag 62. The inner compression airbag 61 is attached to the outer wear-resistant airbag 62. In actual use, the inner compression airbag 61 and the outer wear-resistant airbag 62 are tightly attached together, having a certain expansion and contraction function. The material of the inner compression airbag 61 can be elastic rubber, and the outer wear-resistant airbag 62 can be Kevlar.

[0032] In this embodiment, an air inlet and an air outlet are provided on one side of the cavity 4. In actual use, the air inlet is used to input gas into the buffer mechanism 1, and the air outlet is used for the buffer mechanism 1 to output gas.

[0033] In this embodiment, the cavity 4 is provided with an air inlet pipe 8 and an air outlet pipe 9, corresponding to the air inlet and air outlet. The air inlet pipe 8 is connected to the air source device, and the air outlet pipe 9 is provided with an electrically controlled valve. In actual use, the air source device inflates the cushioning mechanism 1 through the air inlet pipe 8, causing the cushioning mechanism 1 to expand and protect the luggage. The air outlet pipe 9 is used to exhaust the air within the cushioning mechanism 1. It is used in conjunction with the silencer device, and the opening and closing of the exhaust pipe is controlled by the electrically controlled valve, which is controlled by a controller.

[0034] In this embodiment, a support column 41 is provided at the bottom of the cavity 4, and the cavity 4 is mounted on the force-bearing surface through the support column 41. In actual use, the support column 41 is used to fix the cavity 4 and install the cavity 4 to the working position through the support column 41.

[0035] In this embodiment, the pressure detection device 3 is a pressure detection gauge. In actual use, the pressure detection device 3 is a pressure detection gauge for monitoring the air pressure in the buffer mechanism 1 and transmitting the monitoring data to the controller for easy regulation by the controller.

[0036] In this embodiment, the baggage detection device 2 is a photoelectric detector. In actual use, the baggage detection device 2 is a photoelectric detector. The photoelectric detector can be installed on the baggage carousel or on the upstream conveyor. The photoelectric detector is used to detect whether there is baggage injected into the lower end surface of the inclined baggage carousel.

[0037] This embodiment includes a controller, to which the cushioning mechanism 1, luggage detection device 2, pressure detection device 3, and air source device are all electrically connected. In actual use, the controller controls the connected components. By receiving monitoring signals from the pressure detection device 3 and luggage detection device 2, the controller controls the air source device and cushioning mechanism 1, providing cushioning protection for luggage and preventing damage from destructive impacts.

The above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting.
