Description

Technical Field

[0001] This utility model belongs to the field of airport baggage automatic sorting technology, specifically relating to an airport baggage automatic sorting chute belt conveyor. Background Technology

[0002] In existing airport baggage automated sorting systems, a circular conveyor lifts baggage to individual sorting stations within the overhead automated sorting system. The control system then pushes the baggage at each individual sorting station into the baggage collection chute corresponding to each flight, where operators load it onto a vehicle and deliver it to the corresponding flight's cargo hold.

[0003] The original chute structure was a steel frame plate type, without power or deceleration, and tilted at 25 degrees. As luggage was pushed down from a height and slid down the chute, its gravitational potential energy and initial kinetic energy were converted into a large amount of falling kinetic energy, causing collision damage to the luggage. Utility Model Content

[0004] To address the problems mentioned in the background section, this utility model provides an automatic baggage sorting chute conveyor for airports, comprising an original chute assembly, which includes an upper original chute and a lower original chute, with a buffer belt conveyor assembly installed between the upper and lower original chute.

[0005] The buffer belt conveyor assembly includes an adjustable angle short column assembly and an adjustable angle long column assembly, and longitudinal side beam assemblies are installed on the top of the adjustable angle short column assembly and the adjustable angle long column assembly.

[0006] As a preferred embodiment of the automatic baggage sorting chute belt conveyor of this utility model, a baffle assembly is installed on the longitudinal side beam assembly, a transition chute assembly is installed between the upper original chute and the baffle assembly, an electric roller active roller assembly is installed on the longitudinal side beam assembly, and a pair of passive roller assemblies are arranged at both ends of the longitudinal side beam assembly, and a protective cover assembly is arranged around the outer periphery of the electric roller active roller assembly.

[0007] As a preferred embodiment of the automatic baggage sorting chute belt conveyor of this utility model, three idler roller assemblies, as well as tension roller assemblies and alignment roller assemblies are provided between the longitudinal side beam assemblies of the passive roller assemblies.

[0008] In a preferred embodiment of the automatic baggage sorting chute belt conveyor of this utility model, four pallet assemblies are installed on the longitudinal side beam assembly between the passive roller assembly and the three idler roller assemblies.

[0011] In a preferred embodiment of the present invention, an automatic baggage sorting chute conveyor for airports, an electrical control box assembly is mounted on the adjustable angle long column assembly, and a PLC controller is installed inside the electrical control box assembly.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. A high wear-resistant belt conveyor is added to the original chute. This belt conveyor is equipped with an independent PLC control system. Based on the feedback signal from the photoelectric detection element, the PLC calculates the speed of the luggage in real time and controls the start, speed, and stop of the belt conveyor, thereby avoiding damage to the luggage.

[0014] 2. The sensor signals from each set of photoelectric switches are transmitted to the PLC control system. The PLC calculates the initial speed of each piece of luggage as it falls onto the conveyor belt, and automatically controls the starting speed and acceleration / deceleration time of the conveyor belt to ensure a smooth and shock-free descent of the luggage. The system also includes functions such as counting falling luggage and issuing stacking alarms. Through these functions, the goal of reducing or eliminating luggage damage rates is achieved.

[0021] Example 1

[0022] like Figure 1 As shown;

[0023] An automated baggage sorting chute belt conveyor for airports includes the original chute assembly 17.

[0024] In this implementation plan: To address the technical problems existing in the prior art, such as the "original chute structure is a steel frame plate chute structure, without power or deceleration, and tilted at 25 degrees. During the process of luggage being pushed down from a height and sliding down in the chute, its gravitational potential energy and initial kinetic energy will be converted into a large amount of falling kinetic energy, causing collision damage to the luggage body," this problem is obviously a real and difficult-to-solve issue in practical use. Therefore, to solve this technical problem, an automatic airport baggage sorting chute belt conveyor is provided.

[0025] like Figure 1-2 As shown in the figure;

[0026] In conjunction with the above, the original chute assembly 17 includes an upper original chute and a lower original chute, and a buffer belt conveyor assembly is installed between the upper original chute and the lower original chute.

[0027] The buffer belt conveyor assembly includes an adjustable angle short column assembly 1 and an adjustable angle long column assembly 2, with a longitudinal side beam assembly 3 installed on the top of the adjustable angle short column assembly 1 and the adjustable angle long column assembly 2.

[0028] In an optional embodiment, a baffle assembly 5 is installed on the longitudinal side beam assembly 3, a transition chute assembly 4 is installed between the upper original chute and the baffle assembly 5, an electric roller active roller assembly 6 is installed on the longitudinal side beam assembly 3, and a pair of passive roller assemblies 7 are arranged at both ends of the longitudinal side beam assembly 3, and a protective cover assembly 12 is arranged around the outer periphery of the electric roller active roller assembly 6.

[0029] As a preferred embodiment of the automatic baggage sorting chute belt conveyor of this utility model, three idler roller assemblies 8, as well as tension roller assembly 9 and alignment roller assembly 10 are provided between the longitudinal side beam assemblies 3 between the passive roller assemblies 7.

[0030] In a preferred embodiment of the automatic baggage sorting chute belt conveyor of this utility model, four pallet assemblies 11 are installed on the longitudinal side beam assembly 3 between the passive roller assembly 7 and the three idler roller assemblies 8.

[0031] In a preferred embodiment of the present invention, an automatic baggage sorting chute conveyor for airports, a belt 13 is provided between the passive roller assembly 7, the electric roller active roller assembly 6, the tensioning roller assembly 9, and the alignment roller assembly 10.

[0032] As a preferred embodiment of the automatic baggage sorting chute conveyor of this utility model, the baffle assembly 5 is provided with an array of three photoelectric switch assemblies 14 and an alarm light assembly 15.

[0033] As a preferred embodiment of the automatic airport baggage sorting chute belt conveyor of the present invention, the adjustable angle long column assembly 2 is equipped with an electrical control box assembly 16.

[0034] The electrical control box assembly 16 includes a frequency converter, a PLC, and a touch screen. The parameters and variables involved in the PLC's internal program can be manually set on the touch screen of the electrical control box 16.

[0035] Working principle of this utility model:

[0036] The luggage is pushed down from the top of the original slide chute of the original slide assembly 17, passes through the transition slide chute 4, and is detected by the first group of the three photoelectric switch assemblies 14. After receiving the signal, the PLC in the electrical control box 16 controls the frequency converter to start the electric roller active roller assembly 6 at low frequency, and the belt 13 starts at low speed. At the same time, the PLC counts the falling luggage.

[0037] When the luggage passes through the second group of photoelectric switch assembly 14 and is detected, the PLC calculates the speed of the luggage based on the time interval between the blocking of the first two groups of photoelectric switches. The PLC automatically adjusts the frequency of the inverter in the electrical control box 16 to control the rotation speed of the electric roller active roller assembly 6, so that the belt 13 runs at the speed calculated by the algorithm. The luggage runs on the belt conveyor at the set speed and is detected by the bottom group of photoelectric switch assembly 14. At this time, the luggage slides down to the bottom of the original chute of the original chute assembly 17 in a low-speed inertial state, completing the entire process of buffering and decelerating the falling luggage.

[0038] When the third photoelectric sensor in the photoelectric switch assembly 14 is blocked by luggage for a certain period of time, the alarm light assembly 15 will flash red to indicate that luggage has accumulated at the bottom of the original slide of the original slide assembly 17 and the operator has not yet removed the luggage. At this time, the PLC in the electrical control box 16 will control the frequency converter in the electrical control box 16 to stop after a certain period of operation in order to protect the bottom of the accumulated luggage from wear.

[0039] If the operator fails to handle the accumulated luggage for an extended period, all three sets of photoelectric switch components 14 will be blocked for a long time. The PLC-controlled belt conveyor must stop, and the buzzer in alarm light component 15 will sound, prompting the operator to handle the accumulated luggage promptly. The operator can switch the external control output of electrical control box 16 to manual mode to manually operate the belt conveyor at low speed until the accumulated luggage is moved. The operator then presses the reset button, and the entire belt conveyor returns to automatic operation.

[0040] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
