  • Patent number: 5427224
    Abstract: An apparatus for conveying and aligning various types of film packages recovered for recycling. A conveyer of the apparatus is constructed by a pair of parallel belts combined to form a V-shaped bearing gutter and driven in the same conveying direction. The film packages are conveyed on the conveyer and are slid downward through an inclined cylindrical tube which rotates about the longitudinal axis and has spiral ridges on the inner periphery. Thereby, the longitudinal direction of the film packages are aligned with the conveying direction. Then a posture discriminator discriminates between the upright posture and the upside-down posture of the film packages on a first conveying path, based on the position of the viewfinder. The film packages having the upright posture are caused to fall headlong from the first conveying path onto a second conveying path, so as to have the upside-down posture on the second conveying path.
