PURPOSE:To relieve the closing up of articles and shock of the collision between the articles for an article feeding roller conveyer capable of single article alignment stock by providing given positions of each of two chains running in opposite directions to each other with resilient members so that the rollers are rotated due to the contact between the resilient members and the rollers. CONSTITUTION:An article 2 conveyed by a conveyer 1 is fed by stationary but rolling rollers 13. When resilient members 24 and 25 are brought into contact with a roller 13 at its margin 13A by upper and lower chain portions 22 and 23 run by sprockets 18 of upper and lower drive units 16 and 17, respectively, the roller 13 is rotated in a feeding direction or in the reverse direction opposite thereto. Thus, a plurality of the rollers 13 are rotated in turn in the respective directions as the resilient members 24 and 25 progress. Since these members 24 and 25 are arranged at given intervals, the articles 2, forming groups, are intermittently fed and stocked on the roller 13 where an outlet conveyer 26 is connected with the conveyer 1. Since intermittently fed in the reverse direction by the resilient member 25 on the lower chain portion 23 at this time, the articles 2 do not close up together and the shock of collision between the articles is relieved. |
