Cigarette-making machine and tipping paper conveying detection method

The invention discloses a cigarette-making machine and a tipping paper conveying detection method. The cigarette-making machine comprises a tipping paper conveying device and a tipping paper positiondetection device, and the tipping paper position detection device is arranged above the tipping paper conveying device and detects whether an edge of tipping paper is located at a set position. The tipping water position detection device analyzes whether the edge of the tipping paper is located at the set position so that whether deviation or edge curling of the tipping paper occurs can be determined, defect signals can be output to allow the cigarette-making machine to eliminate defect cigarettes and improve the qualified rate of the cigarettes. 本发明公开了一种卷烟机和水松纸输送检测方法。卷烟机包括水松纸输送装置和水松纸位置检测装置，水松纸位置检测装置设置于水松纸输送装置的上方并检测水松纸的边缘是否位于设定位置。水松纸位置检测装置分析水松纸的边缘是否位于设定位置便可判断出水松纸是否跑偏或卷边，从而输出缺陷信号供卷烟机剔除该缺陷烟支进而提高卷烟的合格率。
