<p><P>PROBLEM TO BE SOLVED: To provide a roller conveyance device, capable of conveying carried-in articles in a dispersed manner in a roller width direction and improving the conveyance efficiency in the roller conveyance device by arranging, in each of a plurality of lines of roller members disposed in a roller conveyance direction, high-friction roller portions dispersively in the roller width direction. <P>SOLUTION: A roller conveyance unit 121 of the shoot 100 conveys each article carried in with a width directional speed parallel to the roller width direction in the roller conveyance direction. Each roller member 133 is composed of a plurality of basic roller portions 151-154 having a basic friction coefficient and a plurality of high-friction roller portions 141-143 having a high friction coefficient larger than the basic friction coefficient. In each roller member 133, the high-friction roller portions 141, 143; 142, 143 are arranged with a space in the roller width direction across the basic roller portion 153; 154. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
