  • the groove 81 has the same alignment effect as the slot 80 and is much easier to process than the slot 80. High usefulness.
  • the length and width of the groove 81 are not particularly limited. Industrial applicability
  • the screws conveyed from the screw accommodating portion are not directly supplied to the guide rails, but are guided by the alignment means before being guided to the guide rails.
  • the alignment means before being guided to the guide rails.
  • the present invention is particularly effective when a small screw such as a small screw having a close ratio of the diameter of the head to the length of the shaft and a large thickness of the head is supplied. It demonstrates.

Abstract

L'invention concerne un dispositif d'alimentation en vis installé dans une ligne de montage. Ledit dispositif comprend une partie de réception de vis (22), un tambour rotatif (25) conçu pour acheminer les vis reçues dans la partie de réception de vis (22), un moyen d'alignement (40, 41) conçu pour aligner les vis acheminées par le tambour rotatif (25) et un rail de guidage (48) placé en aval du moyen d'alignement (40, 41), conçu pour porter les têtes des vis alignées. Une fois les vis alignées, elles sont guidées jusqu'au rail de guidage (48), ce qui permet d'éviter que les petites vis se coincent dans ledit rail (48).
