Abstract
Abstract Apparatus is disclosed for extracting and sorting mail from envelopes which have had one edge thereof already severed. The plurality of envelopes with their edges already severed are placed into a hopper and fed from the hopper to a pair of conveyor belts operating along a vacuum manifold through which a vacuum is drawn. The conveyor is indexed to move the envelope to a work station at which two opposed vacuum cups pull the sides of the envelope into an open position to facilitate quick removal of the contents. While the operator is sorting the contents of the envelope into sorting compartments, the conveyor is again indexed to bring the next envelope into place whereupon it is drawn into an open position. An inspection device, such as a photocell arrangement, is positioned at an inspection station to check that the contents have been completely removed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
157 words
Apparatus facilitating extracting and sorting of the contents from envelopes which have been opened on one edge only comprising: a feed hopper into which a plurality of envelopes to be processed are placed; fully exposed conveyor means having a feed station and an opening station; and of configuration to convey an envelope with the opened edge positioned generally upwardly fully exposed along the length of the conveyor means; a substantially flat and continuous work surface extending along and above the conveyor means between the feed station and the work station; feed means for feeding mail from the feed hopper to the feed station of the conveyor means at predetermined times; Conveyor indexing means operating the conveyor means to convey mail from the feed station to the work station at predetermined times; and separating means at the opening station only for drawing the side panels of the envelope apart to expose the contents thereof for ease of removal.
Claim 2
Dependent Claim
157 words
Apparatus facilitating extracting and sorting of the contents from envelopes which have been opened on one edge only comprising: a feed hopper into which a plurality of envelopes to be processed are placed; fully exposed conveyor means having a feed station and an opening station; and of configuration to convey an envelope with the opened edge positioned generally upwardly fully exposed along the length of the conveyor means; a substantially flat and continuous work surface extending along and above the conveyor means between the feed station and the work station; feed means for feeding mail from the feed hopper to the feed station of the conveyor means at predetermined times; Conveyor indexing means operating the conveyor means to convey mail from the feed station to the work station at predetermined times; and separating means at the opening station only for drawing the side panels of the envelope apart to expose the contents thereof for ease of removal.
Claim 3
Dependent Claim
39 words
The apparatus of claim 1 wherein the separating means includes opposed suction members disposed on each side of the envelope which sequentially extend into engagement with the envelope and retract therefrom to draw the sides of the envelope apart.
Claim 4
Dependent Claim
59 words
The apparatus of claim 1 wherein the conveyor means includes an elongate vacuum manifold including a plurality of suction holes therein and at least one continuous conveyor belt positioned adjacent the plurality of holes whereupon an envelope positioned on the belt will be held into conveying engagement with the belt by the suction drawn through the plurality of holes.
Claim 5
Dependent Claim
46 words
The apparatus of claim 3 wherein the feed means is a suction member and is positioned within the elongate manifold and is operable to extend from the manifold to pick up an envelope and retract into the manifold to position the envelope against the conveyor belt.
Claim 6
Dependent Claim
35 words
The apparatus of claim 1 wherein the conveyor means further includes an inspection station and further including inspection means at the inspection station for determining whether the entire contents of the envelope have been removed.
Claim 7
Dependent Claim
22 words
The apparatus of claim 1 further including a pluarlity of sorting compartments positioned adjacent the work station to receive the sorted mail.
Claim 8
Dependent Claim
37 words
The apparatus of claim 1 wherein the conveyor indexing means is actuated immediately upon the removal of the contents of the envelope to position the following enevelope for extraction while sorting of the previously removed contents occurs.
Claim 9
Dependent Claim
151 words
Apparatus facilitating extracting and sorting of the contents from envelopes which have been opened on one edge comprising: a feed hopper into which a plurality of envelopes to be processed are placed; Conveyor means including an elongate vacuum manifold having a plurality of suction holes therin and at least one continuous conveyor belt positioned adjacent the plurality of holes such that an envelope positioned on the belt will be held into conveying engagement with the belt by the suction drawn through the plurality of holes. feed means for feeding mail from the feed hopper to the feed station of the conveyor means at predetermined times; conveyor indexing means operating the conveyor means to convey mail from the feed station to the work station at predetermined times; and separating means at the work station for drawing the side panels of the envelope apart to expose the contents therof for ease of removal.
Claim 10
Dependent Claim
151 words
Apparatus facilitating extracting and sorting of the contents from envelopes which have been opened on one edge comprising: a feed hopper into which a plurality of envelopes to be processed are placed; Conveyor means including an elongate vacuum manifold having a plurality of suction holes therin and at least one continuous conveyor belt positioned adjacent the plurality of holes such that an envelope positioned on the belt will be held into conveying engagement with the belt by the suction drawn through the plurality of holes. feed means for feeding mail from the feed hopper to the feed station of the conveyor means at predetermined times; conveyor indexing means operating the conveyor means to convey mail from the feed station to the work station at predetermined times; and separating means at the work station for drawing the side panels of the envelope apart to expose the contents therof for ease of removal.
Claim 11
Dependent Claim
46 words
The apparatus of claim 8 wherin the feed means is a suction member and is positioned within the elongate manifold and is operable to extend from the manifold to pick up an envelope and retract into the manifold to position the envelope against the conveyor belt.
