Definitions

  • the present invention relates to an optical cigarette filling control device.
  • the present invention relates to a control device for determining the presence or absence of tobacco at the open end of cigarettes on a cigarette manufacturing and/or filter assembly and/or packing machine.
  • the cigarettes are normally subjected to numerous controls, one of which provides for determining the presence or absence of tobacco at the open end of the cigarettes.
  • an optical comparator comprising a light source for illuminating the front open-end surface of the cigarette; a detecting unit featuring a telecamera or similar optical monitoring unit for producing an image of the front open-end surface; and a comparing unit for receiving the monitored image and comparing it with a specimen image.
  • the comparing unit normally also provides for emitting a reject signal in the event the difference between the monitored and specimen images exceeds a given limit.
  • the difference between the two images is one of shading, which, as we know, in the case of the monitored image, varies according to the presence of gaps in the front open-end surface due to the absence of tobacco.
  • the shading of the monitored image has been found to depend largely not only on the presence of said gaps, but also on the colour of the tobacco employed, so that known devices of the aforementioned type involve long, high-cost setup procedures whenever a different type of tobacco is used.
  • an optical device for controlling the filling of cigarettes and characterized by the fact that it comprises, in combination, a sensor and fixed-focus optical means aligned in a fixed position along the optical axis of the optical means and presenting a given focusing plane and a substantially zero depth of field; the focusing plane, in use, being tangent to the end edge of the cigarette positioned substantially coaxial with said optical axis.
  • the above device preferably also comprises a light source for illuminating the end surface of the cigarette; said sensor being designed to receive a beam reflected by said end surface towards said optical means.
  • said sensor is provided with comparing means for emitting a reject signal in response to a signal emitted by the sensor and below a given threshold value.
  • Number 1 in Fig.1 indicates an optical device for controlling the filling of end portion 2 of a cigarette 3.
  • Device 1 comprises a light source 4 for emitting a beam 5 impinging on and for illuminating front end surface 6 of portion 2; and a biconvex lens 7 having an optical axis 8 and a fixed focus 9.
  • Device 1 presents a focusing plane 10 at a given distance A from lens 7, and a substantially zero depth of field; and cigarette 3 is positioned facing lens 7, coaxial with axis 8, and in such an axial position that end edge 11 of cigarette 3 is tangent to focusing plane 10.
  • Device 1 also comprises a sensor 12 located along axis 8, on the opposite side of focus 9 to lens 7, on the opposite side of lens 7 to cigarette 3, and at a given distance B from lens 7, which sensor 12 provides for detecting the contrast value of the image of surface 6 viewed through lens 7 and proportional to the filling of portion 2 of cigarette 3, and may, for example, be of the type described in USA Patent n. 5,107,337.
  • Device 1 also comprises a comparing and control unit 13 for receiving the contrast value of the monitored image from sensor 12, comparing it with a threshold contrast value C, and emitting a reject signal in the event the incoming contrast value is below the threshold value.
