PURPOSE: An indexing speed-reduction apparatus of an APC(Auto Pallet Changer) is provided to relieve a physical impact by reducing the drainage rate of working fluid through an orifice in order to gradually decrease the rotation speed of a table. ;CONSTITUTION: An indexing speed-reduction apparatus of an APC comprises a solenoid valve(40), first through sixth valves(21,22,24,31,32,34), first and second buffer tanks(23,33), first through tenth hydraulic lines(L1~L10), first and second orifices(25,35), and first and second check valves(26,36). The solenoid valve supplies working fluid one of first and second cylinders(12,14). The first through fourth valves are connected to the pressure ports(P) or drain ports(T) of the solenoid valve through the first and sixth hydraulic lines on one side and connected to the first and second cylinders through the second and seventh hydraulic lines on the other side. The second and fifth valves are branched from the second and seventh hydraulic lines to the third and eighth hydraulic lines. The first and second buffer tanks are respectively connected to the drain ports of the second and fifth valves. The third and sixth valves are connected to the drain ports of the first and second buffer tanks through the fourth and ninth hydraulic lines on one side and connected to a drain tank on the other side. The fifth and tenth hydraulic lines are branched from the first and sixth hydraulic lines on one side and branched from the fourth and ninth hydraulic lines on the other side. The first and second check valves prevent the backflow of working fluid to the first and second orifices.;COPYRIGHT KIPO 2011
