Abstract
In a method an arrangement for controlling a dynamic scale is set via an input unit according to the respective requirements for processing a mixed mail stack, the setting optionally ensuing on the basis of selected shipping parameters and/or operating parameters that are displayed via a display unit. A modification of the operating parameters and data corresponding to the setting can be undertaken and stored in the non-volatile memory of the scale. Weighing of a supplied piece of mail takes place and a controller drives a conveyor of the scale such that the piece of mail is transported to a further processing station dependent on the operating parameters and data that have been set.
Claims1
A method for controlling a dynamic scale of individually weighing postal items in a mixed mail stack, comprising the steps of:
- controlling transport of a postal item from a mail stack in a dynamic scale to and from a weighting location on a conveyor by a controller;
- entering a weight range having an upper limit into said controller;
- upon weighing said postal item, determining in said controller whether saidupper limit has been exceeded;
- if said upper limit is exceeded, stopping said conveyor via said controller andthereby stopping transport of further postal items from said mail stack;
- allowing a decay time associated with mechanical vibrations at said weighinglocation to expire;
- after said decay time, conducting a static weighing, during a weighing time, atsaid weighing location of the postal item which exceeded said upper limit;
- after said weighing time, re-starting said conveyor via said controller;
- and
- emitting an output signal from said scale identifying the weight of said postal item which exceeded said upper limit obtained during said static weighing.
