Apparatus for aligned supply of fastening parts

An apparatus for aligned supply of fastening parts for supplying fastening parts having a head part at one end of a shaft part, such as bolts, rivets, and pins, to an automatic assembling machine, comprising:

• a pressing punch moving up and down,
• a supply passage for supplying the fastening parts in a position of lateral direction with the shaft part leading end ahead and the head part behind, continuously from a lateral direction to a lower position of the pressing punch, and
• a rotary holding claw body disposed at a lower position of the pressing punch, for gripping the fastening parts supplied in a position of a lateral direction by way of the supply passage, passing through an intersection of an axial line of the pressing punch and an axial line of the supply passage, rotating and displacing by a specific angle about a lateral axial line orthogonal to the both axial lines, and positioning and holding the fastening parts coaxially with the pressing punch at a lower position of the pressing punch,
• wherein the rotary holding claw body has a pair of mutually opposing disk-shaped gripping claws, the both disk-shaped gripping claws are forced to press each other by push springs, and the fastening parts are gripped by the both disk-shaped gripping claws, and when the pressing punch descends to press the head part of the fastening parts, the both disk-shaped gripping claws are pushed and expanded by resisting the push springs, and the fastening parts are extruded from the space between the both disk-shaped gripping claws.
