Abstract

This article describes a technique for unloading print wheels automati- cally from canisters without distortion or damage and transferring them to an assembly machine. Referring to the drawings, Fig. 1 is a top view of the assembly station showing canisters positioned on a sixteen-position rotary turret table A. The table top dial outer ring rotates and is equipped with canister edge guides N that locate the canister. There are also sixteen spring-loaded ball plungers M that engage a recess in the canister and clamp the canister towards the center of the dial table. A sixteen-position table with sixteen locating nests is shown. This (Image Omitted) table processes print wheels before delivery to the in-line assembly machine shown in side view in Fig. 2. Fig. 3 is a section across A-A in Fig. 2.

Automatic Unloading of Print Wheels From Canisters and Transferring Them to an Assembly Machine

This article describes a technique for unloading print wheels automati- cally from canisters without distortion or damage and transferring them to an assembly machine. Referring to the drawings, Fig. 1 is a top view of the assembly station showing canisters positioned on a sixteen-position rotary turret table A. The table top dial outer ring rotates and is equipped with canister edge guides N that locate the canister. There are also sixteen spring-loaded ball plungers M that engage a recess in the canister and clamp the canister towards the center of the dial table. A sixteen-position table with sixteen locating nests is shown. This

table processes print wheels before delivery to the in-line assembly machine shown in side view in Fig. 2. Fig. 3 is a section across A-A in Fig. 2. A geared electric motor C lifts and retracts pusher drive pins G attached to ball nut F. Electric clutch D drives ball nut F. Fail safe electric brake E prevents the ball nut from drifting down when clutch D is disengaged. The drive ball nut F operates the three drive pins G. Equalizing air-operated clamping head assembly H is equipped with a pair of clamping jaws J. The clamping jaws have a V-cut groove at the bottom of the jaws, so when they clamp the print wheel on the round molded sprue, it will bring the part on center location. A part being placed on the process bushing is shown. Upper limit switch K sets up a signal to retract drive pins G to base position. Lower limit switch L indicates drive pins G have retracted so that the turret table can index and deliver another canister to the work station.
