Description

Technical Field

[0001] The present invention relates to the technical field of logistics conveying equipment, and more particularly to a noise reduction conveying system and method for a luggage spiral chute. Background Art

[0002] At present, the existing passenger baggage spiral chute conveying system of the airport is that the upstream conveying equipment inputs the passenger baggage into the spiral chute at a fixed conveying speed. However, due to the fixed lead of the spiral chute, the diversity of passenger baggage, and the lack of luggage shape detection and luggage weight weighing at the front end of the spiral chute, in order to ensure that the luggage is not stranded, the passenger baggage is conveyed to the downstream conveying equipment through the spiral chute to meet the conveying requirements at a fixed and faster speed. It often happens that when heavier luggage or plastic boxes with smoother surfaces slide down the spiral chute, the speed is fast, which will generate loud noise and easily cause damage to passenger luggage, which is often complained by passengers.

[0003] Therefore, how to provide a noise reduction conveying system and method for a luggage spiral chute is an urgent problem to be solved by those skilled in the art. Summary of the invention

[0004] In view of this, the present invention provides a luggage spiral chute noise reduction conveying system and method, which can reduce the noise generated during luggage conveying, reduce damage to passenger luggage, and improve passenger satisfaction.

[0005] In order to achieve the above object, the present invention adopts the following technical solution:

[0006] A baggage spiral chute noise reduction conveying system is used for conveying baggage, comprising an upper installation device and a lower installation device, wherein the upper installation device comprises an upstream baggage handling system, a weighing device, a baggage shape detection device and a variable speed conveyor which are sequentially installed on an upper installation base, and the baggage shape detection device is installed on the weighing device or the upper installation base; the lower installation device comprises a spiral chute and a downstream conveyor which are installed on the lower installation base; a feeding end of the spiral chute is connected to the variable speed conveyor, and a discharging end is connected to the downstream conveyor; the baggage shape detection device, the weighing device and the variable speed conveyor are all electrically connected to an industrial control computer.

[0007] In the luggage spiral chute noise reduction conveying system disclosed by the present invention, the upstream luggage handling system conveys the luggage to the weighing device, and after the luggage detection device and the weighing device weigh and inspect the appearance of the luggage, the relevant inspection data are uploaded to the industrial computer, and the industrial computer determines the appearance and weight inspection value of the luggage according to the data, and controls the variable speed conveyor to step and convey; the variable speed conveyor is provided, and the industrial computer can control the conveying speed of the variable speed conveyor, and provide a suitable speed for the conveying of the luggage, which not only reduces the noise when the luggage slides down, but also avoids it from staying on the spiral chute.

[0008] Preferably, a spiral chute buffer component is fixed on the inner side of the side plate of the spiral chute, and a spiral chute speed reduction curtain device is suspended at intervals of the spiral section, and a spiral chute noise reduction device is fixed on the inner side.

[0009] The beneficial effect of adopting the above technical solution is that the spiral chute buffer component can not only reduce the conveying speed of the luggage, but also prevent the luggage from being damaged when it collides with the side panels during the downward conveying process.

[0010] Preferably, the spiral chute noise reduction device is a non-metallic object with sound absorption function.

[0011] The beneficial effect of adopting the above technical solution is that the noise reduction device absorbs the collision sound during the downward conveyance of luggage, thereby reducing noise pollution.

[0012] Preferably, the spiral chute deceleration curtain blocking devices are arranged at intervals at each spiral segment of the spiral chute.

[0013] The beneficial effect of adopting the above technical solution is that the spiral slide groove deceleration curtain blocking device can block the sliding luggage interval and reduce noise.

[0014] Preferably, the spiral chute is supported by supporting columns.

[0015] The beneficial effect of adopting the above technical solution is that the spiral chute is supported by the supporting columns, thereby enhancing the stability of the structure.

[0016] Preferably, it also includes a support frame, which is fixed to the spiral section of the outer periphery of the spiral chute and fixedly connected to the support column; the spiral chute noise reduction device is fixed to the inner side of the support frame.

[0017] The beneficial effect of adopting the above technical solution is that the spiral chute deceleration curtain device and the noise reduction device are supported by a supporting frame, thereby reinforcing the stability of the spiral chute structure.

[0018] The present invention also discloses a method for reducing noise when conveying luggage through a spiral chute. After the luggage is processed by the upstream luggage processing system 7, the operation of conveying the luggage downward through the spiral chute is completed according to the following steps:

[0019] Step 1: The baggage is transported to the first detection area, the second detection area and the weighing range formed by the weighing device and the baggage shape detection device 6 through the upstream baggage handling system;

[0020] Step 2: The luggage shape detection device and weighing device detect the shape and weight of the luggage, and feed back the detection values ​​to the industrial computer;

[0021] Step 3: The industrial computer determines the shape and weight of the luggage;

[0022] a) If the shape and weight of the luggage meet the set values, the luggage 3 is conveyed to the spiral chute for downward conveyance through the control of the industrial computer;

[0023] b) If the shape and weight of the luggage do not meet the input setting value, the industrial computer will change the speed of the variable speed conveyor;

[0024] Step 4: The industrial computer determines whether the luggage can be transported downward, that is, whether the variable speed conveyor 4 is ready to continue;

[0025] a) If the luggage can be transported downward, the industrial computer issues a command, and the variable speed conveyor 4 does not need to change speed, and the luggage is transported to the spiral chute for downward transportation;

[0026] b) If the current speed of the variable speed conveyor does not match the size and weight of the conveyed luggage, the variable speed conveyor will be changed according to the instructions issued by the industrial computer to prevent the luggage from being stranded, and the luggage will be transported to the spiral chute for transportation;

[0027] Step 5: The baggage arrives at the spiral chute and is transported to the downstream conveyor through the spiral chute. In this process, the industrial computer controls the speed of the variable-speed conveyor according to the detection values ​​provided by the baggage shape detection device and the weighing device through calculation, and provides different speeds for different baggage according to different baggage. The baggage in the spiral chute is buffered and damped by the spiral chute buffer component and the spiral chute speed reduction curtain device, and the spiral chute noise reduction device can effectively reduce noise.

[0028] It can be seen from the above technical solutions that, compared with the prior art, the present invention discloses a baggage spiral chute noise reduction conveying system, which has the following beneficial effects:

[0029] First, the baggage is processed by the variable speed conveyor before passing through the spiral chute, so that when the baggage is conveyed to the downstream conveyor, baggage of different shapes or weights adopts different sliding speeds, which reduces the noise and collision of baggage during sliding, and provides guarantee for the stable operation of subsequent baggage;

[0030] Secondly, during the baggage transportation process, the baggage is processed by the spiral chute buffer component, the spiral chute noise reduction device and the spiral chute speed reduction curtain device, which effectively reduces the noise in the workplace;

[0031] Finally, by using different speeds for luggage of different shapes or weights, the chance of luggage being delayed is reduced, ensuring that passengers and luggage arrive at their destination on the same flight, reducing passenger complaints and improving the airport service index.
