摘要:
An automatic doubles and sheet thickness detector is disclosed that operates by comparing consecutive sheet materials that are delivered to a rotating drum.The consecutive sheet materials pass under two spaced apart rollers that are movably biased against the drum. If a sheet of greater thickness or a double sheet passes under one of the rollers, it will be displaced a greater distance from the drum surface than the other roller. This displacement is magnified by means of elongated pivot arms, which are attached to each roller. The magnified movement is detected by means of an optical arrangement comprising a light source, a photodetector, and a pair of mirrors. The mirrors are each secured to a distal end of a respective pivot arm. The light source casts a beam that reflects off each mirror towards the photodetector. When one of the arms is displaced more than its companion arm, such as when a double or thicker sheet lies between one of the rollers and the drum, the light beam will not be directed towards the photodetector. If each arm is displaced a like amount, as when consecutive single sheets are of like thickness, the photodetector will receive the reflected light, and therefore indicate a proper sheet.

A document collating and inserting system having displays for document count verification. A plurality of bank checks belonging to a check set are fed, counted and stacked at a stacking station while simultaneously an associated statement is fed to an imaging station where a number imprinted thereon is imaged by a video camera and displayed on a video monitor. The number represents a predetermined number which should equal the actual number of checks counted, the actual count also being displayed. An operator makes a visual comparison of the two displayed numbers and, if they are in agreement, initiates a cycle of the system thereby forming a collation of the statement and checks and transporting them to a holding station. From the holding station the collation is inserted within an envelope provided by an envelope feeder during the next cycle of the system. If the two numbers are not in agreement a mismatch switch is provided for the operator to activate before cycling the system. After indicating the mismatch the operator must remove the erroneous collation from the holding station in order to cycle the system once again. After removing the erroneous collation and cycling the system, an envelope is not provided by the envelope feeder, thereby avoiding the possibility of inadvertently postage metering and mailing an empty envelope.

A stopping mechanism in an inserting machine having a feeder for feeding documents seriatim to a transport deck therebelow, the feeder being angled with respect to the deck. The stopping mechanism stops the documents at a predetermined position with respect to a previously collated package situated on a ramp located upstream of the deck and elevated with respect to the deck. The stopping mechanism comprises a pivotable paddle located downstream of the feeder substantially parallel to the direction of feed, a device for biasing the lower end of the paddle away from the transport deck to permit a collated package to pass therebelow without contacting the pivotable paddle, and a device for pivoting the lower end of the paddle downward adjacent the transport deck for a short period of time at an appropriate moment in order to stop the forward motion of a document exiting the feeder at a predetermined position on the transport deck.

Method and apparatus for half folding sequentially and nesting a plurality of paper sheets. The apparatus includes a buckle chute folder, the folder having a first pair of feed rollers rotatable at a given velocity, and a device for continuously feeding the paper sheets in shingled relationship at a second velocity greater than the given velocity to the feed rollers. The shingled relationship is defined by an overlap of the sheets of at least one-half of the length of the sheets. By using the apparatus and method, any desired number of sheets may be folded sequentially and nested one inside the other.

A high speed sheet-material separating and feeder system is disclosed which handles a wide range of mixed thicknesses and sizes of envelopes and sheets. In a free running mode, the system can conservatively handle 30,000 pieces of mail per hour. The sheets are stacked at one end of the system, and are fed to a first of two separator mechanisms. The first separator mechanism is adjusted for thicker sheets of the range. Sheets leaving the first separator are then fed to the second of the two separator mechanisms. The second separator is adjusted for thinner sheets of the range. Sheets leaving the second separator are ejected one at a time, in seriatim, where they then can be fed to other sheet handling equipment for processing.

An improvement in a collating machine for stacking sheets of paper being fed seriatim thereto from a singulating feeder in the same order as the sheets appear in the singulating feeder. The collating machine includes a belt for transporting the sheets of paper, a ramp for lifting a succeeding sheet of paper over and onto a preceding, stopped sheet of paper, and a stopping device for stopping each sheet of paper after the sheet has been lifted by the ramp. The improvement includes a removable stacking device for stacking the sheets of paper in the reverse order as the sheets appear in the singulating feeder.
摘要:
An improvement in a document feeding device having a hopper oriented at an acute angle with respect to a horizontal plane and able to support a pack of documents to be fed seriatim therefrom. The improvement comprises at least one pad having a high coefficient of friction material situated on the upper surface of the hopper whereby the effect of the weight of the documents situated in the hopper above the pad on the pressure of the pack situated below the pad is decreased.

A high speed sheet-material separating and feeder system is disclosed which handles a wide range of mixed thicknesses and sizes of envelopes and sheets. The sheets are stacked at one end of the system, and are fed to a dual separator mechanism having two separator members. The dual separator mechanism has a first separator member which is adjusted for thicker sheets of the range, and a second separator member which is adjusted for thinner sheets of the range. Sheets leaving the dual separator are ejected one at a time, in seriatim, where they then can be fed to other sheet handling equipment for processing.

A high speed, vacuum-controlled sheet-material separating and feeder system is disclosed which handles a wide range of mixed thicknesses and sizes of envelopes and sheets. The vacuum feeding of this system reduces frictional wear on the feed and separating rollers. The sheets are stacked at one end of the system, and are fed to a first of two vacuum-controlled separator mechanisms. The first separator mechanism is adjusted for thicker sheets of the range. Sheets leaving the first separator are then fed to the second of the two separator mechanisms. The second separator is adjusted for thinner sheets of the range. Sheets leaving the second separator are ejected one at a time, in seriatim, where they then can be fed to other sheet handling equipment for processing.
摘要:
A flap separating mechanism for distending a flap from a body portion of an envelope.An envelope moving through a mail handling system may require its flap to be moistened and sealed. As a prelude to the moistening procedure, the flap of the envelope must be separated from the body portion. The separating mechanism disclosed herein comprises a rotatably affixed belt conveyor and an adjacent ski-like stripper member. The stripper member is movably biased toward said conveyor to provide a normal force on envelopes disposed therebetween.The deflapping mechanism can accommodate envelopes of varying thickness, while providing a fixed plane for the printing of postage on the body portion of the envelopes.
