<p>PURPOSE:To make the device economical and increase its dispatching speed by retaining the rollers which have various dimensional tolerances per their dimensional tolerances and incorporating it in a retainer. CONSTITUTION:The full number retainer 13 retains the rollers 10 which have been pre-classified per dimensional tolerance, in a fixed condition and per types, respectively. For example, the full number retainer 13 which retains the rollers in accordance with the dimensional tolerances of the retainer by the computer command signals is selected, slides, and sends the full number of rollers retained by itself into the guide path of the roller block 19. The chuck 24 moves upward and positions the retainer 11 around the lower part of the roller block 19. It also makes one of its retaining windows 11a face to the delivery outlet 21 of the guide path 20. As a result, the rollers 10 which change their direction at the guide path 20 are sent in the retaining windows 11a.</p> |
