Abstract
There is disclosed a new and improved envelope processing machine. The machine includes a processing station arranged to present each envelope in an opened condition to an operator in one-by-one relation to facilitate the removal of contents from or the insertion of materials into the envelopes by the operator. A detecting means downstream from the processing station acts upon the envelopes one at a time for sensing a predetermined event corresponding to the suspected absence of complete removal of the contents from or complete insertion of materials into the envelopes. An illumination means actuable in response to the detecting means sensing the predetermined event is arranged to direct light through the envelopes to afford visual verification of the predetermined event by the operator.
Claims12
A machine for processing envelopes comprising:
- a processing station with means for opening an envelope, means for feeding envelopes from a supply in one-by-one relation;
- conveying means with entry and delivery ends receiving envelopes from the feeding means in underlying support at the entry end of the conveying means in predetermined spaced relation and arranged to present each envelope at the processing station to render the same to an opened condition accessible to an operator in one-by-one relation to facilitate the removal of contents from or the insertion of materials into the envelopes by the operator;
- detecting means spaced from the processing station in the direction of the delivery end of the conveying means a distance sufficient to allow a previously opened envelope to relax toward closed condition at the detecting means for acting upon the conveyed and relaxed envelopes one at a time for sensing a predetermined event corresponding to suspected incomplete removal of the contents from or incomplete insertion of materials into the envelopes;
- and illuminating means longitudinally proximate to the delivery end of the conveying means with an associated envelope support surface for receiving therefrom and supporting an envelope generally relaxed from its previously opened condition under the moving contact influence of the conveying means and released from support by the conveying means with sliding arrest on the envelope support surface over the illuminating means in stationary positioning on the envelope support surface independent of the moving contact influence of the conveying means in association with the illuminating means which is actuable in response to said detecting means sensing said predetermined event for directing light through the stationary envelope received in association with the illuminating means to afford visual verification of said predetermined event by the operator and permissive unobstructed handling of the stationary envelope as the predetermined event may dictate.
A machine which facilitates the removal of contents from envelopes comprising:
- a processing station with means for opening an envelope, means for feeding envelopes from a supply in one-by-one relation;
- conveying means with entry and delivery ends receiving envelopes from the feeding means in underlying support at the entry end of the conveying means in predetermined space relation and arranged to present the envelopes in one-by-one relation at the processing station to render the same to an opened condition to facilitate the removal of the contents from the envelopes by the operator;
- detecting means spaced from the processing station in the direction of the delivery end of the conveying means a distance sufficient to allow a previously opened envelope to relax toward closed condition at the detecting means for sensing the conveyed envelopes for the presence of unremoved contents within the envelope relaxed from its previously opened condition and for providing a control signal responsive thereto;
- and illumination means longitudinally proximate to the delivery end of the conveying means with an associated envelope support surface and arranged to receive and support the relaxed envelopes under the moving contact influence of the conveying means and released from support by the conveying means with sliding arrest on the envelope support surface over the illumination means in stationary positioning on the envelope support surface independent of the moving contact influence of the conveying means in association with the illumination means after being sensed by said detecting means and actuable responsive to said control signal for directing light through the stationary envelope to afford visual verification by the operator of the presence of the unremoved contents.
