초록 ▼

A mail piece weighing scale for use with automated mail processing apparatus in which a plurality of mail processing components are disposed along a feed path for processing mail pieces moving seriatim along the feed path. The weighing scale has a platform, the upper surface of which is aligned with and forms a segment of the feed path. A transport means for moving mail pieces across the scale platform is mounted on the platform so that the platform and the transport means form an integral unit which constitutes the tare weight of the scale when it is calibrated to register 0 weight. The transport means includes a pair of transport units mounted beneath the scale platform with drive elements thereof protruding through apertures in the platform so as to contact mail pieces disposed on the upper surface, and a resilient pressure means is mounted on the scale platform in overlying relationship to both of the transport units so as to press mail pieces into firm driving engagement with the drive elements of the transport means. The platform and transport means assembly is mounted on a load cell which in turn is mounted in a base frame, with the result that the transport means does not have to be retracted beneath the surface of the platform in order for the scale to weight mail pieces.

[ I claim:] [1.] A mailing processing apparatus comprising:an elongate feed path; anda plurality of processing components disposed along the feed path for processing mail pieces moving seriatim along the feed path;wherein at least one of said processing components is a weighing scale for weighing mail pieces, said weighing scale including a mounting base, a load cell fixedly connected to said mounting base, a scale platform mounted on said load cell and positioned such that an upper surface thereof is aligned with and forms a segment of the feed path, transport means for moving mail pieces across said scale platform along a direction of said feed path, and means for mounting said transport means on said scale platform whereby the tare weight of both said scale platform and said transport means is imposed on said load cell prior to said load cell being subjected to the weight of a mail piece;wherein said transport means includes first and second transport units which are laterally spaced from each other in a direction transverse to said direction of said feed path, said first and second transport units respectively including first and second drive means which each have a portion thereof projecting above the upper surface of said scale platform which first and second drive means cooperate together to move mail pieces across said scale platform and to prevent mail pieces from skewing out of alignment during movement across said scale platform,wherein said transport means further includes first and second resilient pressure means mounted on said scale platform in respective overlying relationship to said first and second drive means for maintaining mail pieces in firm driving engagement with said first and second drive means, said first and second resilient pressure means also forming part of the tare weight on said load cell.
