Abstract

Disclosed is a retractable mechanism useful for changing the direction of translation of a driven object while maintaining positive drive. It is especially useful in handling envelopes in automatic teller machines, where thick, rigid envelopes must turn sharp corners during processing.

Envelope Drive

       Disclosed is a retractable mechanism useful for changing
the direction of translation of a driven object while maintaining
positive drive.  It is especially useful in handling envelopes in
automatic teller machines, where thick, rigid envelopes must turn
sharp corners during processing.

      The mechanism, as shown in Figure 1, consists of a
spring-loaded, retractable parallel linkage which supports a
pressure-roller assembly, a pivoting chute to which this is mounted,
and a stationary belt drive assembly.

      While chute B is in the home position (see Figure 1), pin F
holds link D and pressure rollers E clear of the envelope path.  The
envelope is inserted into opening A and comes to rest against gate C.
After the envelope fully enters the chute, a motor rotates the chute
in a clockwise direction.  As the chute rotates, torsion spring G
causes link D to rotate, forcing rollers E against the envelope and
capturing it against the side of the chute.

      When the chute reaches its final position (see Figure 2), the
envelope is held between rollers E and belt H, which now protrudes
into the chute.  The exit of the chute is no longer blocked by gate
C, which does not rotate the full distance.  Motor I then engages,
driving belt J, which in turn drives belt H.  Belt H drives the
envelope into the next segment of the processing path.  When the
envelope has fully exited the mechanism, the chute rotates back to
its ho...
