Abstract
A method and an arrangement for detecting a filling level in a tissue dispenser for dispensing portions of a continuous web of tissue from a tissue roll is adapted for use with. a tissue dispenser for dispensing portions of the continuous web of tissue from the tissue roll. The method comprises the steps of counting portions of the tissue dispensed by the tissue dispenser, determining an initial filling level depending on the counter data and an initial tissue type information, and determining a verified filling level depending on the counter data when a roll exchange of a tissue roll from a first tissue roll position to a second tissue roll position in the tissue dispenser has occurred.

A method for detecting a filling level in a tissue dispenser for dispensing portions of a continuous web of tissue from a tissue roll, the method comprising the steps of:
- counting portions of the tissue dispensed by the tissue dispenser to generate counter data;
- determining an initial filling level depending on the counter data and an initial tissue type information;
- determining a verified filling level depending on the counter data when a roll exchange of a tissue roll from a first tissue roll position to a second tissue roll position in the tissue dispenser has occurred, and
- determining a verified tissue type information when a roll exchange of a tissue roll from a first tissue roll position to a second tissue roll position in the tissue dispenser has occurred, wherein the verified tissue type information is determined at the time of the roll exchange;
- wherein the initial filling level corresponds to the filling level which is derived from the initial tissue type information with the counter data at the time of determination as long as no verified tissue type information has been determined;
- wherein the verified filling level is determined taking into account the event of the change in position of the tissue roll and the counter data corresponding to this time of exchange of a tissue roll from a first tissue roll position to a second tissue roll position;
- and
- wherein the determination of the verified filling level depends on data relating to the roll exchange, namely a reduced diameter of the tissue roll at the time of the roll exchange and/or a maximum diameter of the tissue roll in the second tissue roll position, such that:
- the initial tissue type information is an information which is set in a default;
- the initial tissue type information corresponds to a standard tissue type;
- the tissue type information comprises information on at least one or more of the following:
- length of tissue on the tissue roll,
- number of layers,
- thickness of tissue,
- tissue material, and
- single use or multiuse tissue;
- or
- the initial filling level corresponds to the filling level which is derived from the initial tissue type information with the counter data at the time of determination as long as no verified tissue type information has been determined.
An arrangement for detecting a filling level in a tissue dispenser for dispensing portions of a continuous web of tissue from a tissue roll, the arrangement comprising:
- a counter adapted to count portions of the tissue dispensed by the tissue dispenser and adapted to generate counter data;
- and
- a control unit adapted to receive counter data from the counter, wherein the control unit is adapted to determine a verified filling level depending on the counter data when a roll exchange of the tissue roll from a first tissue roll position to a second tissue roll position in the tissue dispenser has occurred, wherein the control unit is adapted to determine a verified tissue type information when the roll exchange of the tissue roll from the first tissue roll position to the second tissue roll position in the tissue dispenser has occurred, and wherein the verified tissue type information is determined at the time of the roll exchange;
- wherein the verified filling level is determined taking into account the event of the change in position of the tissue roll and the counter data corresponding to this time of exchange of a tissue roll from a first tissue roll position to a second tissue roll position, and
- wherein the determination of the verified filling level depends on data relating to the roll exchange, namely a reduced diameter of the tissue roll at the time of the roll exchange and/or a maximum diameter of the tissue roll in the second tissue roll position, such that:
- the control unit is adapted to determine an initial filling level depending on the counter
- data and an initial tissue type information;
- the initial tissue type information is an information which is set in a default,
- the initial tissue type information corresponds to a standard tissue type,
- the tissue type information comprises information on at least one or more of the following:
- length of tissue on the issue roll,
- number of layers,
- thickness of tissue,
- tissue material,
- single use or multiuse tissue;
- or
- the initial filling level corresponds to the filling level which is derived from the initial tissue type information with the counter data at the time of determination as long as no verified tissue type information has been determined.
