| 摘要 |
A dripper detection device (20) for an irrigation pipe manufacturing system comprising a continuous pipe feeder capable of making a pipe (100) equipped with drippers (120) having a water outlet (126), said pipe (100) circulating along a predetermined circulation direction (X-X') while keeping the drippers' water outlet (126) in a predetermined orientation, said dripper detection device (20) including a laser detection unit (22) with a laser source (24) emitting a laser beam (25) directed to the pipe outer face (104) location where drippers (120) are present at regular intervals, and a laser signal receiver (26) which receives and analyses the laser beam (27) reflected on the pipe outer face (104) to provide a transformed reflected signal which contains information about the passage of each dripper (120) facing said laser detection unit (22). |
