Zusammenfassung: | The method for controlling a dynamic scale for flat goods lying on their side, includes a controlling of the transport of the flat goods and has a continuous counting of encoder pulses and a weight measurement of a moving flat good which is started if the trailing edge of the flat good has reached a first sensor. A first count state W1 of the counter is stored if the leading edge of a flat good reaches a second sensor but a valid weight measurement result is not present. A step (111) of the method is then reached in which a weight measurement takes place with a transport velocity reduced step by step, wherein after a step-down of the transport velocity of the flat good a subsequent weight measurement is performed with a next lowest transport velocity, wherein the current counter state is then queried if neither a valid weight measurement result, nor can it be established that the trailing edge of the flat good has reached the first sensor, although the leading edge of a flat good has reached a second sensor, as well as a check as to whether the current counter state corresponds to a sum of the stored counter state and a predetermined count value; and repetition of the querying and sub-steps of the step after the check as long as the current counter state has not yet reached the sum, and with an additional step-down of the transport velocity of the flat good and validity check of the weight measurement result in at least one additional step (113, ..., 119) if the current counter state reaches the sum.
La méthode de contrôle dune balance dynamique pour articles plats posés sur le côté comprend le contrôle du transport des articles plats et le comptage continu des impulsions de codeur et la mesure du poids dun article plat en mouvement enclenchée si le flanc arrière de larticle plat a atteint un premier capteur. Un premier niveau de compte (W1) du compteur est stocké si le flanc avant dun article plat atteint un deuxième capteur, mais quune mesure valide du poids nest pas présente. Une étape (111) de la méthode est ensuite atteinte, dans laquelle une mesure du poids a lieu à vitesse de transport réduite étape par étape, une mesure subséquente du poids étant réalisée après une réduction dun cran de la vitesse de transport de larticle plat. Létat actuel du compteur est ensuite vérifié si ni une mesure valide de poids ni létablissement que le flanc arrière a atteint le premier capteur, bien que le flanc avant ait atteint un deuxième capteur, et vérifié pour déte |
