연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록

A material handling system and method of use for increasing throughput at security checkpoints. The material handling system includes a dual input conveyor with a merge conveyor leading to a detection system. At the output of the detection system is a diverting mechanism which will divert the items leaving the detection system to one of two output conveyors, corresponding to the input conveyors. A reject mechanism and accompanying conveyor may be provided, in addition to a bin return and control system.

A material handling system, comprising: a plurality of input conveyors for conveying items; a merge device to singulate the flow of the items from the plurality of input conveyors into a single transportation path; a plurality of output conveyors to provide buffer space for the items exiting from the single flow transportation path; and an output diverting device positioned between an output of the single transportation path and the plurality of output conveyors to separate and direct the items to a respective one of the plurality of output conveyors; wherein the merge device directs movement of the items from one of the plurality of input conveyors to the single transportation path while blocking items on any remaining of the plurality of input conveyors; and the output diverting device diverts movement of the items exiting from the single transportation path to one of the plurality of output conveyors while blocking items from flowing to any remaining of the plurality of output conveyors. 9. The system of claim 1, further comprising at least one of: a detector to regulate the movement of the items between (i) each of the plurality of input conveyors and the merge device and (ii) the single transportation path and each of the plurality of output conveyors; and a scanning or reading device to capture information concerning the items such that the items are matched at the output of the single transportation path. 10. A material handling system, comprising: a plurality of input conveyors for conveying items; a merge device to singulate the flow of the items from the plurality of input conveyors into a single transportation path; a plurality of output conveyors to provide buffer space for the items exiting from the single flow transportation path; and an output diverting device positioned between an output of the single transportation path and the plurality of output conveyors to separate and direct the items to a respective one of the plurality of output conveyors; wherein the output diverting device is a vertical moving device to move rejected items to reject conveyor at different height than the plurality of output conveyors. 11.
