The invention relates to a roller way type temporary storage material bin with self-weight power. The roller way type temporary storage material bin comprises an upper rack, a lower rack, guide polished shafts, material stopping and dividing air cylinders, electric rollers, unpowered rollers, a first set of opposite type sensors and a second set of opposite type sensors. The ends on the same sides of the upper rack and the lower rack are provided with pin shaft supports respectively and fixedly connected through pin shafts. The other end of the upper rack and the other end of the lower rack are provided with adjusting bolt connecting seats and connected through adjusting bolts. A plurality of six-groove aluminum profiles are fixedly arranged in the conveying direction of the upper rack in an overall parallel mode. The guide polished shafts are evenly and alternately arranged in the direction, parallel to the six-groove aluminum profiles, of the upper rack, and the electric rollers are arranged at the two ends of the guide polished shafts in the vertical direction. The unpowered rollers are sequentially arranged on the inner sides of the two ends of the guide polished shafts and are perpendicular to the six-groove aluminum profiles. The roller way type temporary storage material bin has the beneficial effects that the cost is low, reliability and stability are achieved, the occupied area is small, and the mounting requirement is low; the effects of overall roller way conveying, temporary storage and sorting are achieved through adjustability.
