Abstract

This article describes an automatic level diskette buffer tool which maintains diskettes at a predetermined height for robot handling while providing operator access to service the tool without interrupting the process. The tool, disclosed herein, utilizes diskette cannisters [*] for presenting unjacketed diskettes to a two-height position manipulator. It is suitable for both manual and automatic servicing with minimal interference of the process cycle. The tool, shown in side elevation in Fig. 1, consists of two independent sub-assemblies coupled only when required for joint operation. An indexing mechanism rotates a pair of diskette cannisters 1 with a full one 2. The cannisters fit into keyed bases 3 to insure only the appropriate diskettes (untested in this instance) are loaded into the machine. Fig.

Auto-Level Diskette Buffer

This article describes an automatic level diskette buffer tool which maintains diskettes at a predetermined height for robot handling while providing operator access to service the tool without interrupting the process. The tool, disclosed herein, utilizes diskette cannisters [*] for presenting unjacketed diskettes to a two-height position manipulator. It is suitable for both manual and automatic servicing with minimal interference of the process cycle. The tool, shown in side elevation in Fig. 1, consists of two independent sub-assemblies coupled only when required for joint operation. An indexing mechanism rotates a pair of diskette cannisters 1 with a full one 2. The cannisters fit into keyed bases 3 to insure only the appropriate diskettes (untested in this instance) are loaded into the machine. Fig. 2 is a cross-section of the elevator drive mechanism. This drive mechanism maintains a constant diskette level relative to the manipulator but retracts to permit indexing by bringing the buffer cannister into the work position, when the cannister in the workstation is depleted. This allows constant diskette feed without interrupting production cycle time. The indexing mechanism has a central spindle 4 mounted in bearings 5 which reciprocates 180 degrees via a pneumatic rotary actuator 6. Mechanical stops 7 provide positional repeatability while limit switches 8 indicate that end of travel has been reached. The cannisters are guided vert...
