DETECTION DEVICE, MANUFACTURING MANAGEMENT SYSTEM, DETECTION METHOD, AND CONTROL PROGRAM

The invention provides a detection device, a manufacturing management system, a detection method, and a control program. By detecting the film conveying state when the film is manufactured, the phenomenon of production stop caused by breakage and the like is prevented from happening in advance. A detection device (90) for use in a production line of a film roll, the detection device (90) being provided with: an imaging unit (91) for capturing an image of a monitored region on the surface of a film (F8) conveyed in a stretching step and/or a trimming step, and generating a continuous frame image; a processing unit (93) that generates comparison image data by comparing two frame images having a predetermined time difference, and generates an index of the degree of shake of the film on the basis of the generated comparison image data; and an output unit (95) that outputs the index. 提供一种检测装置、制造管理系统、检测方法以及控制程序。通过检测制造膜时的膜输送状态，将断裂等导致生产停止的现象的发生防患于未然。一种在膜卷的生产线上使用的检测装置(90)，检测装置(90)具备：摄像部(91)，对在拉伸工序和/或修边工序中被输送的膜(F8)的表面的
