Abstract

Disclosed is a device which inhibits damaging closure of automated plate machines with aligning features. Many automated machines rely on similar aligned features to allow proper and full closure of the plates during operation. Frequently, when the similar features are not properly aligned, damage to the features and/or plates results when closure is attempted.

Block-Lock Ensuring Feature Alignment of Closing Plates

       Disclosed is a device which inhibits damaging closure of
automated plate machines with aligning features.  Many automated
machines rely on similar aligned features to allow proper and full
closure of the plates during operation. Frequently, when the similar
features are not properly aligned, damage to the features and/or
plates results when closure is attempted.

      The device (see figure) consists of an upper plate, a lower
plate, matching features within the plates, an alignment template and
a block-lock.  The upper and lower plates contain features which can
be moved to positions of corresponding alignment or misalignment.
The upper and lower plates are opened or closed with respect to each
other by undisclosed automated means.

      When one or more features within the upper and/or lower plates
are not properly aligned prior to closing the plates, severe damage
can result to the plates and/or features.  The current method of
ensuring this alignment is by occasionally verifying relative feature
positions with an alignment template (as shown in the figure).  As
shown, the proper alignment would allow the "round peg" features on
the bottom plate to fit into all corresponding "round hole" features
on the top plate. However, the alignment template has several
drawbacks:  the automated machine must be stopped for manual
insertion/ removal of the alignment template, and it is still
possible to...
