PURPOSE: A screw distributing unit is provided to simplify the structure by supplying screws to an automatic screw fastener using one cylinder and a slider. CONSTITUTION: A screw distributing unit comprises a body(100), a screw supply unit(101), first and second cam grooves(110,120), first, second, third, and fourth ejecting ports(131,132,133,134), and a slider. A first bottom dead center(114) of a first cam groove is arranged in the same line with the screw supply unit. The top dead centers(115,116) of the first cam groove are placed on both sides based on the first bottom dead center. The second bottom dead center(124) of the second cam groove is placed on the same line with the screw supply unit. The third and fourth dead centers(125,126) of the second cam groove are placed on both sides based on the second bottom dead center. The first cam groove is longer than the second cam groove. |
