A servo indexing table for rotary and horizontal shifting of paper bunch

A servo indexing table for rotary and horizontal shifting of paper bunches comprising:

• a stationary platform having a top plate and a bottom plate being connected by plurality of vertical posts by defining space therebetween;
• a drive unit being accommodated within said space;
• said top plate and said bottom plate each having a central aperture;
• said drive unit including a pinion gear mounted on the servo motor, an intermediate shaft having a first pulley and a second pulley being mounted along a length thereof a main shaft having a pulley being in mechanical connection with the first pulley of the intermediate shaft and a cam, at least one auxiliary shaft, having a pulley being in mechanical connection with the second pulley of the intermediate shaft and a cam, juxtaposed shafts each having a cam and that are suitable for receiving drive power from said auxiliary shaft, a vertically driven shaft having a lower end received within the central aperture of the bottom plate and a top end being extended from the central aperture of the top plate a spider head mounted on the top end of said driven shaft, spider arms located at regular distance and radially extended from the said spider head;
• each spider arm having a gripper at its free end;
• the driven shaft being rotatable for a predefined rotating angle with help of the servo motor which includes gear mechanism suitable for causing the spider head and therefore, the spider arms to rotate;
• the drive power renderable to the main shaft by the servo motor is providable to the intermediate shaft through a mechanical connection between the first pulley and the pulley of the main shaft, wherein from the intermediate shaft, the drive is transferable to the pulley of the auxiliary shaft through the second pulley, and wherein the drive power is transferable to the juxtaposed shafts through universal joints respectively for shifting the paper bunch in horizontal rotary motion in synchronized manner.
