A thickness measuring device for measuring the thickness dimension of an article being conveyed along a conveyor system comprises a rotary encoder, and a lever arm pivotally mounted upon the shaft of the rotary encoder. The lever arm has an end portion thereof disposed in contact with the article conveyor so as to be deflected by an article conveyed along the conveying path. Deflection of the lever arm causes the rotary shaft of the rotary encoder to undergo a predetermined amount of rotation which is indicative of the thickness dimension of the article being conveyed. The system is also operatively associated with a storage bin such that when a plurality of articles, having a predetermined cumulative thickness dimension, are detected, further conveyance of articles to the storage bin is terminated. The system further comprises a central processing unit (CPU) which has incorporated therein improved software which permits the system to accurately determine the thickness dimensions of articles having substantially constant, but relatively large thickness dimensions, as well as articles having variable dimensions.

A drop pocket system and method reorients flat articles in a serial stream, by horizontally receiving a horizontally moving, serial input stream of substantially vertically oriented flat articles, sensing reception of each flat article, engaging each sensed flat article, accelerating each engaged flat article into substantially downward movement, and conveying each flat article with the downward movement into a substantially horizontal orientation and movement.

Drop pocket system and method for reorienting flat articles

A system and method reorients flat articles in a serial stream, by receiving a horizontally moving, serial input stream of substantially vertically oriented flat articles each having a downwardly oriented primary edge, laterally diverting the flat articles in the serial input stream alternately between a pair of separate paths, impeding horizontal movement of each flat article in each separate path, accelerating each flat article with impeded horizontal movement in the direction of its primary edge, and delivering substantially horizontally oriented flat articles from each separate path.

A thickness measuring device for measuring the thickness dimension of an article being conveyed along a conveyor system comprises a rotary encoder, and a lever arm pivotally mounted upon the shaft of the rotary encoder. The lever arm has an end portion thereof disposed adjacent to the conveyor path so as to be deflected by an article conveyed along the conveying path. Deflection of the lever arm causes the rotary shaft of the rotary encoder to undergo a predetermined amount of rotation which is indicative of the thickness dimension of the article being conveyed. The system is also operatively associated with a storage bin such that when a plurality of articles, having a predetermined cumulative thickness dimension, are detected, further conveyance of articles to the storage bin is terminated.

A follower mechanism is provided for use in a system for feeding flat articles, such as mixed mail, which follower mechanism includes a paddle assembly connected to a mount so as to be pivotable between a feed position and an inactive position, and mechanism for permitting the paddle mount to be freely moved in either direction when the paddle assembly is in its inactive position, but to be drivable only in the forward direction when the paddle is in its feed position. A counterbalance mechanism is provided to control downward movement to the paddle and to assist in the lifting of the paddle. A mechanism may also be provided for positively disengaging the mount for the paddle from the drive mechanism.
