항공보안 X-선 검색장비의 트레이 피더 장치{Tray Feeder of Aviation Security X-ray Inspection Equipment}Tray Feeder of Aviation Security X-ray Inspection Equipment}

본 발명은 항공보안 X-선 검색장비의 트레이 피더 장치에 관한 것이다.The present invention relates to a tray feeder device for aviation security X-ray inspection equipment.

일반적으로, 보안 검색 장치는 X-선을 투과시켜 얻는 영상 정보를 이용하여 위험물 등을 검출하게 된다. 다만, X-선 만을 이용하여 영상정보를 획득하게 될 경우, 검색대상물의 형태를 육안으로 볼 수 있으나 물질 정보에 관해 알 수 없게 된다. 이에, 종래에는 검사대상체를 향해 중성자선을 추가로 조사하여 검사대상체의 물질 정보를 확보하고자 하였으나, 이 경우, 중성자를 발생시키기 위한 방사선 발생부와 중성자를 검출하기 위한 검출시스템이 별도로 제작되어야 하므로 제조 비용이 증가하게 된다. 또한, 이러한 시스템은 두 가지 종류의 방사선을 각각 검사 대상체에 조사한 후, 투과된 방사선으로부터 검사 대상체의 영상 정보를 각각 획득해야 하는 구조를 가지므로 시스템이 대형화되어야 하는 문제점이 있게 된다. 이와 함께, 검사대상체를 향해 중성자선을 추가로 조사하여 검사대상체의 물질 정보를 확보할 경우, 검사대상체를 투과한 중성자와 x-선 사이에 서로 간섭되는 현상이 발생하여 노이즈(noise)로 작용하게 되어 검사대상체의 영상 정보의 질이 낮아지게 되는 문제점이 있다. 이에, 중성자선을 이용하더라도 검사대상체의 형체가 유사한 물질로 이루어질 경우에는 검사대상체의 정보 획득이 어렵다. 특히, 폭발물이나 마약, 핵물질 및 테러방사선 등과 같이 위험물질은 그 형체를 특정하기 어려운 분말이나 액체로 구성되므로, 유사한 형체를 갖는 물질로 이루어진 화물과 함께 적재될 경우(예: 밀가루포대 속 폭발물) 보안검색 장치로 분별하기 어렵다. 이 경우, 보안 검색 장치를 통해, 투과된 x-선과 중성자선을 각각 이용하여 항만 또는 공항에서는 화물이나 우편물 등의 신속한 검사가 이루어지면서도, 투과된 x-선과 중성자선 사이에 발생할 수 있는 간섭 현상을 줄임으로써 물질의 영상 정보의 질을 확보할 수 있는 새로운 방안이 요구된다.In general, a security search device detects a dangerous substance by using image information obtained by transmitting X-rays. However, when image information is acquired using only X-rays, the shape of a search object can be seen with the naked eye, but material information cannot be known. Therefore, in the past, neutron beams were further irradiated toward the object to be inspected to secure material information of the object to be inspected, but in this case, the radiation generator for generating neutrons and the detection system for detecting neutrons must be manufactured separately. cost will increase. In addition, since this system has a structure in which image information of the inspection object must be respectively obtained from the transmitted radiation after irradiating two types of radiation to the inspection object, respectively, there is a problem in that the system must be large. In addition, when neutron beams are additionally irradiated toward the test object to obtain material information of the test object, a phenomenon occurs between the neutrons and x-rays that have passed through the test object, which causes interference to act as noise. Therefore, there is a problem in that the quality of image information of the test object is lowered. Therefore, even if neutron beams are used, it is difficult to obtain information on a test object when the test object is made of a similar material. In particular, dangerous substances such as explosives, narcotics, nuclear materials, and terrorism radiation are composed of powder or liquid whose shape is difficult to specify, so when loaded with cargo made of substances having similar shapes (e.g., explosives in flour bags) It is difficult to distinguish with the security screening device. In this case, an interference phenomenon that may occur between transmitted x-rays and neutron rays, even though cargo or postal items are quickly inspected at ports or airports by using the transmitted x-rays and neutron rays through the security screening device, respectively. A new method is required to secure the quality of material image information by reducing .

종래의 x-ray 검색 장비는 단일 컨베이어를 통해 물체가 이송되므로 스캐너를 통과하여 배출된 물체를 다시 한번 스캔할 필요가 있는 경우 상기 물체만 별도로 컨베이어를 역회전시켜 이동시킬 수 없는 문제가 있다.Since objects are transported through a single conveyor in the conventional x-ray scanning equipment, when an object discharged through a scanner needs to be scanned again, there is a problem in that only the object cannot be moved by reversely rotating the conveyor separately.

이에, 본 발명은 스캐너 후방에 피더를 설치하여 스캐너의 스캔 속도에 맞춰 스캔이 완료되면 후방에 배치된 컨베이어를 통해 스캐너로 물체를 유입시킬 수 있는 항공보안 X-선 검색장비의 트레이 피더 장치를 제공하는데 목적이 있다.Accordingly, the present invention provides a tray feeder device of an aviation security X-ray inspection equipment capable of introducing objects into the scanner through a conveyor disposed at the rear when scanning is completed according to the scanning speed of the scanner by installing a feeder at the rear of the scanner. has a purpose to

컨베이어는 구획이 분할될 수 있으며, 각각의 구획은 컨베이어 상을 이동하는 물체의 속도가 같거나 상이할 수 있다.The conveyor may be divided into sections, and each section may have the same or different speeds of objects moving on the conveyor.

컨베이어에는 물체의 이동 방향을 따라 제1 컨베이어, 제2 컨베이어, 제3 컨베이어, 제4 컨베이어를 포함할 수 있다. 제1 컨베이어, 제2 컨베이어, 제3 컨베이어 및 제4 컨베이어는 순차적으로 배치될 수 있다.The conveyor may include a first conveyor, a second conveyor, a third conveyor, and a fourth conveyor along the moving direction of the object.

걸림방지를 위한 구조는 피더 내부에 설치되어 물체의 걸림이 발상되는 주요 부위, 걸림의 종류 등을 고려하여 설치될 수 있다.A structure for preventing jamming may be installed inside the feeder in consideration of the main part where the object is jammed, the type of jamming, and the like.

걸림해소를 위한 자동화 설계는 물체의 걸림을 감지(센서에 의한 감지 및 영상의 왜곡에 의한 감지 포함)하고, x-ray 재촬영 여부의 결정기준, 컨베이어 후진 여부를 결정 기준 및 위치별 끼임을 해소 방법 등을 고려하여 설계할 수 있다.The automation design for jamming detects the jamming of objects (including detection by sensors and detection by distortion of images), determines whether to retake x-rays, determines whether to move the conveyor backwards, and eliminates jamming by position. It can be designed considering the method, etc.

피더의 출구에는 제3 컨베이어가 설치되며, 제3 컨베이어에는 x-ray스캐너가 설치될 수 있다.A third conveyor is installed at the outlet of the feeder, and an x-ray scanner may be installed on the third conveyor.

x-ray 스캐너는 제3 컨베이어를 통해 이송되는 물체에 x-ray를 조사할 수 있으며, 조사된 물체의 x-ray 이미지를 생성할 수 있다.The x-ray scanner may irradiate x-rays to an object transported through the third conveyor and generate an x-ray image of the irradiated object.

x-ray 스캐너의 입구 및 출구에는 x-ray 차폐커튼이 설치되어 인체에 손상을 가할 수 있는 방사선이 누출되는 것을 방지할 수 있다.X-ray shielding curtains are installed at the inlet and outlet of the x-ray scanner to prevent leakage of radiation that can damage the human body.
