Abstract:
1. An apparatus for aligned supply of fastening parts for supplying fastening parts having a head part at one end of a shaft part to an automatic assembling machine, said apparatus comprising: a supply passage configured to continuously supply the fastening parts in a position of lateral direction with the shaft part leading end ahead and the head part behind; a rotary holding claw body configured to position and hold the fastening parts supplied by way of the supply passage; a pressing punch disposed above the rotary holding claw body and configured to press the head part of the fastening parts by moving up and down relative to the rotary holding claw body; a first axial line which passes through an intersection of an axial line of the pressing punch and an axial line of the supply passage and which is orthogonal to the axial lines of the pressing punch and the supply passage; wherein the rotary holding claw body includes a pair of mutually opposing disk-shaped gripping claws forced to press against each other by push springs acting parallel to the first axial line, and is configured to rotate by a specific angle about the first axial line; wherein the disk-shaped gripping claws are oriented so that the plane of the disk-shaped portion is always parallel to the axial lines of the pressing punch and the supply passage; wherein the rotary holding claw body is configured to rotate while gripping, between the pair of disk-shaped gripping claws, the fastening parts supplied in a position of lateral direction from the supply passage, so that the fastening parts are in a position of longitudinal direction with the head part of the fastening parts upward, and to position and hold the rotated fastening parts coaxially with the pressing punch; and wherein when the pressing punch descends and presses the head part of the fastening parts, the disk-shaped gripping claws are configured to push and expand parallel to the first axial line so that the fastening parts are pushed out from between the disk-shaped gripping claws.
