    • PROBLEM TO BE SOLVED: To eliminate the defective detection of a sheet joint and the malfunction of a detector in a corrugated cardboard sheet production line and to materialize an automated detection means which is improved in sheet joint detection accuracy.
      SOLUTION: In a method for detecting the sheet joint of a corrugator, the leading edge of the second waiting corrugated cardboard base paper 7 is stuck to the end edge of the first corrugated cardboard base sheet 6 being delivered to a corrugated cardboard sheet production process to carry out sheet joint, and a cut sheet S including the sheet joint 5 is removed selectively by detecting the sheet joint 5 on the downstream side of a corrugated cardboard sheet production process. The sheet joint 5 or a partial domain of a corrugating medium CC in its neighborhood is pressed between a single facer 13 and a bridge part 17 to form a flat domain P. The flat domain P is detected by a distance sensor 63 set on the upstream side of a produced corrugated cardboard cutting process (cutter 25). The cut sheet S including the sheet joint 5 is removed selectively on the basis of detection information.

    • 要解决的问题:为了消除瓦楞纸板生产线中的片接合的缺陷检测和检测器的故障,并且实现了提高了片接合检测精度的自动检测装置。 解决方案:在用于检测瓦楞纸机的片接头的方法中,第二等待的瓦楞纸原纸7的前缘被粘贴在第一瓦楞纸板基片6的端边缘上,被送到瓦楞纸板 通过检测瓦楞纸板制造工序的下游侧的片材接合部5,能够选择性地除去包含片材接合部5的切断片材S的生产工序。 板状接合部5或其附近的波纹状介质CC的局部区域被压在单面13和桥接部17之间,形成平坦的区域P.平坦区域P由设置在上游侧的距离传感器63检测 一边生产瓦楞纸板切割工艺(切割机25)。 基于检测信息选择性地去除包括片接合部5的切断片S. 版权所有(C)2009,JPO&INPIT
