PURPOSE:To obtain smooth operation of a carrier roller device for a curved conveyor by providing two rollers disposed in a V shape with a horizontal roller interposed therebetween and two auxiliary rollers disposed on both sides of the horizontal roller at a trough angle. CONSTITUTION:Rollers 3 are disposed in a V shape and at the back thereof a roller 4 is horizontally provided so as to interpolate the central space between the rollers 3, and rollers 5 are provided on both sides of the roller 4 at an angle slightly larger than the trough angle of the rollers 3. Thus constructed, the rollers 3 in a V shape, horizontal roller 4 and auxiliary rollers 5 cooperate to prevent the central portion of the belt from rising so as to achive assured performance of the conveyor and smooth operation thereof. |
