Envelope weighing apparatus with gripping compensation for variable thickness envelopes

Patent Number: 8106315
Publication Date: 2012-01-31
Inventor: Turner, Bryan

Methods and apparatus for weighing an article, such as a mail piece, while the article is moving at high speed. An article (900) is received from an intake transport (1200), and gripped in a weighing station (1310), in between a capstan roller and a pinch roller (1316), which are synchronized to minimize slipping. A first precision servo system (1252, 1250) alters the speed of the article, and in the process acquires torque data for storage and analysis ...

Method and apparatus for dynamically check weighing objects conveyed at adjustable rates using varying filter lengths

Patent Number: 8106314
Publication Date: 2012-01-31
Inventor: Klauer, Alfred

A method and an apparatus for dynamically checking the weight of objects (18a-c) which are guided across a weight-sensitive zone (14) of a weighing device (12) at an adjustable conveying rate by a conveying mechanism (20a-c). At regular intervals, the weight-sensitive zone (14) supplies individual measured weight values (E₁, . . . , E_n) from which resultant weight values are derived in a digital evaluation ...

Method and apparatus for dynamically check weighing conveyed objects, using filter lengths that vary with object size

Patent Number: 8101875
Publication Date: 2012-01-24
Inventor: Klauer, Alfred

A method and an apparatus for dynamically check weighing objects (18a-c) that are guided across a weight-sensitive zone (14) of a weighing device (12) by a conveying mechanism (20a-c). At regular intervals, the weight-sensitive zone (14) supplies individual measured weight values (E₁, . . . , E_n) from which resulting weight values are derived in a digital evaluation unit (16) by calculating mean ...

Controlling a scale in connection with a container of pourable bulk materials

Patent Number: 8097820
Publication Date: 2012-01-17
Inventor: Klubertanz, Kevin

A method of controlling a scale in connection with to a carrier of pourable bulk materials. The scale involved has a control with a display and control buttons. Upon a first press of a first control button, the system is transitioned into a “tare” mode and displays a base, or tare, value. Upon a second press of the first control button, generally after unloading some or all of the load, the difference in weight from the first press is saved to a storage medium, and a value displayed ...
