Description

[0001] The invention relates to the technical field of conveying equipment, and in particular to a material discharge structure of a roller conveyor. Background Art

[0002] Roller conveyors are widely used in automated production lines for conveying goods, especially in packaging, logistics, warehousing and other industries. After conveying goods, traditional roller conveyors generally have certain volume and weight requirements for passengers' luggage in aviation or specific shipping, and usually need to be manually inspected for handling and diversion. This method is not only inefficient, but also has high labor costs, which is not conducive to the rapid passage of passengers and preparation for departure. In order to improve production efficiency and automation level, an efficient roller conveyor unloading structure is needed. Summary of the invention

[0003] The object of the present invention is to provide a material unloading structure for a roller conveyor, which realizes automatic detection, automatic diversion and unloading of objects through reasonable design of a docking module, a detection module, a diversion module and a diversion channel, thereby improving the automation degree and efficiency of the conveyor system.

[0004] To this end, a material unloading structure of a roller conveyor is proposed, which comprises a docking module, a horizontal conveyor belt, a detection module, a diversion module and a diversion channel; The docking module, the horizontal conveyor belt, the detection module, the diversion module and the diversion channel are connected in sequence. There are three groups of diversion channels, which are respectively arranged at the three diversion ports of the diversion module; The docking module is used to connect to the roller conveyor. After the docking module receives the items, they enter the detection module. After being detected by the detection module, they are diverted through the diversion module according to the detection results of the detection module and enter one of the three groups of diversion channels.

[0005] Preferably, the docking module includes a docking chassis, a receiving platform, a receiving slideway, a buffer conveyor belt and a height adjustment cylinder; The buffer conveyor belt is arranged on the docking chassis; There is also a height adjustment cylinder on the docking chassis; there is no receiving platform on the output shaft of the height adjustment cylinder; The receiving platform is hinged to one end of the receiving slideway, and the other end of the receiving slideway is hinged to the buffer conveyor belt.

[0006] It can be seen that by adjusting the height of the receiving platform through the height-adjusting cylinder, it can be connected to different roller conveyors to improve applicability.

[0007] Preferably, the detection module includes a detection housing, an entry conveyor belt, an exit conveyor belt, a dynamic weighing conveyor, a laser scanner and an image capture camera; The dynamic weighing conveyor is arranged in the detection housing; the inlet conveyor belt and the outlet conveyor belt are respectively arranged at two ends of the detection housing and are respectively connected to the dynamic weighing conveyor; The laser scanner is used to scan the height dimension of the object and is arranged at the top of the detection housing, facing the dynamic weighing conveyor; The image capture camera is arranged in the detection housing through a bracket, and is used to capture the appearance image of the object, so as to obtain the proportion, and calculate the volume of the object in combination with the size data obtained by the laser scanner.

[0008] Preferably, there are two groups of image capture cameras, which are respectively arranged at the top and side of the detection shell and face the article conveying area on the dynamic weighing conveyor.

[0010] Preferably, there is no flexible guide plate on the hinge between the receiving platform and the receiving slideway, and at the hinge between the other end of the receiving slideway and the buffer conveyor belt.

[0011] It can be seen that a flexible guide plate is provided at the connection point, which makes the transition smoother and effectively avoids the collision of luggage. In addition, the flexible material can send a certain deformation as the overall connection angle changes due to the change in the height of the receiving platform, and always plays the role of transition.

[0012] Preferably, the device is provided with a control platform, which electrically controls a docking module, a horizontal conveyor belt, a detection module, a diversion module and a diversion channel; a processing blade is provided in the control platform, and a volume calculation algorithm is built in to calculate the volume of the item.

[0013] The built-in control platform is used to control the conveying parts and driving parts in each module to achieve orderly unloading.

[0014] Preferably, a guide and positioning device is provided on the side of the flat conveyor belt.

[0015] Preferably, the guiding and positioning device comprises a positioning arc frame, and two groups of the positioning arc frames are provided, which are respectively located above the conveying surface on both sides of the horizontal conveyor belt.

[0016] By providing a positioning arc frame, positioning during the transmission process is achieved by changing the curvature of the arc frame and the relative distance between two groups of arc frames, which is beneficial to the operation of the subsequent detection module.

[0017] Preferably, there are no guide wheels on the positioning arc frame.

[0018] By providing guide wheels, guidance is provided during the positioning process to avoid hard collision of the luggage, which is beneficial to the protection of the luggage.

[0019] The docking module provided in the present invention is used to receive the articles transported by the roller conveyor and provide support for the subsequent detection and diversion operations of the articles. The flat conveyor belt is connected between the docking module and the detection module, and is used to smoothly transport the articles to the detection module. The detection module is used to detect the size, weight and other data of the transported articles, and detect the appearance and volume of the articles through dynamic weighing conveyors and laser scanners and other equipment. The diversion module diverts the articles according to the detection results of the detection module, and sends the articles to different diversion channels respectively. The diversion channel provides a transmission path for the articles after diversion, and accurately diverts the articles.

[0020] The roller conveyor unloading structure provided by the present invention can realize automatic detection, diversion and unloading of items by integrating multiple functional modules such as docking module, detection module, diversion module, diversion channel, etc., which greatly improves the automation degree and work efficiency of the conveying system. In particular, through the combination of laser scanner, image capture camera and dynamic weighing conveyor, the volume and weight detection of items can be completed efficiently, and accurate diversion can be achieved. This system not only reduces manual operation and improves production efficiency, but also ensures accurate handling of items, and has broad application prospects.

[0021] The roller conveyor unloading structure of the present invention can effectively solve the problems of low diversion efficiency and many manual operations in the prior art, and has a high degree of automation and reliability. Its innovative design can improve the accuracy of article conveying and diversion, is suitable for various automated production lines, and has significant economic benefits and market application value.
