Abstract

A vacuum source is applied directly to a strip storage cell to locate a moving vane selection chute so that a strip element is directed into the desired cell. In the majority of pneumatic random access strip storage systems, the storage selection devices for transporting the strip from a reading station back to the storage cell usually employ mechanical incremental actuators. These move either the storage cell or the entire input chute.

Pneumatic Storage Selection Device

A vacuum source is applied directly to a strip storage cell to locate a moving vane selection chute so that a strip element is directed into the desired cell. In the majority of pneumatic random access strip storage systems, the storage selection devices for transporting the strip from a reading station back to the storage cell usually employ mechanical incremental actuators. These move either the storage cell or the entire input chute.

This device includes circular array storage member 10 having a plurality of radially displaced storage cells or chutes 12, 14, and 16 in it. Movable vane structure 18 is rotatably mounted about the pivot center. As a vacuum is applied to, for example, cell 14, vane 18 lines up with cell 14. This is due to air flow directly from input chute 20 and also around the leading edges of vane 18. Vane 18 can be located adjacent either of cells 12 or 16 by appropriately applying a vacuum to them.

The trailing edge portion 22 of vane 18 is positioned within structure 24 so that a substantially air tight seal is maintained between structure 24 and vane 18. The strip is shown entering input chute 20 from whence it enters vane 18 and subsequently pass into cell 14. Damping of the motion of vane 18 can be accomplished in a number of ways including the provision of a cam lever transducer or the like. A duct or port 26 is shown near the leading edge of vane
18. Port 26 allows atmospheric air to now from chamber 2...
