Method and configuration for dynamic control of the liquid supply to a moisturizing storage means
First Claim
1. A configuration for dynamic control of a liquid supply to a moisturizing storage device for a moisturizing apparatus for application of a sealing liquid to envelope flaps of letter envelopes and having a tank for storing the sealing liquid, the configuration comprising:
- a pump for supplying the moisturizing storage device with the sealing liquid from the tank;
an evaluation and control circuit;
at least one sensor electrically connected to said evaluation and control circuit and disposed in an area of the moisturizing storage device in a movement path of the envelope flaps, said sensor producing a signal to initiate said pump when an envelope flap passes said sensor;
electrodes connected during operation to said evaluation and control circuit, said electrodes including;
device electrodes disposed in the moisturizing storage device and forming at least first and second measurement cells, andtank electrodes defining a third measurement cell disposed in said tank;
said evaluation and control circuit programmed to;
on wetting of said tank electrodes of said third measurement cell by the sealing liquid, measure a resistance measured value of the sealing liquid stored in the tank of the moisturizing apparatus;
perform a subsequent qualitative analysis for determining a nature of the sealing liquid used on a basis of at least one of a determined electrical conductance and a determined specific electrical conductivity and at least one corresponding material parameter functioning as a comparison value;
carry out measurements of further resistance measured values corresponding to an amount of the sealing liquid stored in the moisturizing storage device; and
carry out dynamic control of the liquid supply to the moisturizing storage device in dependence on the corresponding material parameter and of at least one of a conductance determined from the further resistance measured values or a corresponding value of a specific electrical conductivity determined during the measurements of the amount of the sealing liquid stored in the moisturizing storage device.

Abstract
A method and a configuration provide dynamic control of a liquid supply for a moisturizing storage device for sealing glued edges of a envelope flap of letter envelopes. Once a measured value has been measured for a sealing liquid which is stored in the tank of a moisturizing apparatus, the type of sealing liquid that is used is qualitatively analyzed on the basis of the measured value and of at least one material parameter as a comparison value. The amount of liquid stored in the moisturizing storage device is then measured by at least one further measurement to allow dynamic control of the liquid supply to the moisturizing storage device as a function of the material parameter and of at least one measured value, which is related to the liquid consumption, in the result of the at least one measurement of the amount of liquid stored in the moisturizing storage device.
