The conditions specified for the simulations are: rodless
cylinder, cylinder bore size [phi] = 0.32 m; cylinder length l = 1m; compressed air supply pressure [P.sub.s] = 6 x [10.sup.5] N/[m.sup.2]; initial position x = -0.5 m; initial velocity [??] = 0 m/s; initial chamber pressures [P.sub.a] = 4.5 x [10.sup.5] N/[m.sup.2]; and [P.sub.b] = 4.2 x [10.sup.5] N/[m.sup.2]; [K.sub.S] = 0; [K.sub.C] = 0; and [K.sub.f] = 15 Ns/m.
The Lintra Lite series of compact rodless
cylinders is available in three diameters: 25, 32 and 40 mm.
Activated by a proximity switch, a rodless
pneumatic cylinder raises and lowers carts to or from the return track at the beginning and end of an assembly cell.
The plate is suspended from an oversized rodless
cylinder capable of ejecting an off spec.
Roblin said the Lith-7 employs a sealed rodless
cylinder and mechanical stop shocks in place of the Lith-10's servo motor and ball screw, maintaining mechanical accuracy and sacrificing some speed - according to Walker about 20 plates per hour.
A rapidly growing, medium-sized company, Tol-O-Matic makes more than 1200 different products ranging from custom rodless
cylinders to rotary actuators.
Based on a proprietary concept that meshes magnetically coupled rodless
cylinders with linear bearings, it improves movement of all components.
