Definitions

• the present invention relates to a dispenser according to the preamble of claim 1 and to a method according to the preamble of claim 13.
• the mechanism In the case of wet wipes, the mechanism also creates uncontrollable soiling, which can lead to unhygienic or even harmful fertilizers.
• the cleaning cloth mentioned there made of known, usually paper or synthetic material, which is soaked with a skin-friendly, also known cleaning liquid, remains hygienically stored in the dispenser until the detector reports a need.
• the drive mechanism activated by the detector then transports the cloth in the direction of unwinding until a separation line and / or perforation, ie the unrolling of a portion, is detected by the built-in sensor, so that after further transport, with the drive stopped, it is torn off by manual pulling in front of the dispenser - and can be used without being touched in any way.
• the solution according to the invention enables a very hygienic structure of the dispenser and ensures simple operation and economical maintenance.
• This procedure has the advantage that in the "standby position", for example, towels soaked with volatile substances do not dry out even after several hours. If the dispenser is not used during the day, only a narrow strip dries out, so that the tissue can also be used perfectly the next time it is removed.
• the separating line or perforation which serves as a tear-off edge, is located just before the fictitious contact lines of the two rollers when viewed in the development direction.
• the fabric web is held securely in a force-fitting manner; Even in the case of a non-axial removal, this only tears at the dividing line or perforation, which ensures reliable portionwise delivery.
• the detector mentioned in the patent claim can be a proximity switch, an infrared detector, a light barrier, but also a simple microswitch, which detects or actuates another process, for example.
• the control can also be implemented with the help of commercially available microprocessors, with corresponding control, monitoring and reporting functions; in the simplest case, a notoriously known relay circuit is sufficient for control.
• the embodiment according to claim 2 allows placement of the electro-optical sensor in front of or behind the axes of the rollers; If direct control of the sensor is selected, then this or its associated light guide is on the user side, after the rollers, but if a follow-up time is provided, the sensor is in front of the rollers. As such, a single roller connected to the drive mechanism is sufficient.
• the embodiment specified in claim 3 is particularly recommended for smooth and / or very damp cleaning wipes, since it is slip-free.
• the embodiment according to claim 4 is very reliable and almost maintenance-free.
• the contact pressure on the web of connected cleaning wipes can be increased in a simple manner by the measures according to claim 5.
• O-rings according to claim 6 are particularly favorable since they protect the cloth and cause a centering alignment of the web.
• the latter By aligning the sensor according to claim 7, the latter can be positioned closer to the axes of the rollers, as a result of which the strip of material not stored in the cassette can be minimized.
• the dividing line and / or perforation can be partially opened, which simplifies their monitoring and simplifies tearing off the section again.
• the variant according to claim 9 is advantageous if the cloth is not or only slightly moist.
• the sensor With a finger-like support surface, the sensor can be assigned even closer to the axes of the rollers: a fixed surface increases the friction on the cloth. lein, which can lead to dripping of liquids.
• the combination of the aforementioned measures with a reflecting surface serves for improved detection of the dividing line and / or perforation by the sensor.
• the speed of the drive can be checked with the same sensor.
• the dispenser according to claims 1 to 11 is very energy efficient, so that it can be configured autonomously according to claim 12.
• the monitoring of the transport roller with the measures according to claim 14 results in a simple function check and, in the event of a drop in speed, indicates a low battery charge; a sudden increase in signal amplitude indicates an empty cassette or a torn ribbon.
• the method according to claim 15 is particularly advantageous if more than one donor is to be used in a predetermined order.
• This can be, for example, a first dispenser equipped with toilet paper, which controls a second dispenser provided with wet wipes by simple monitoring of the removal or a rotary movement, by means of the detector mentioned in claim 1, and makes it available in the manner described.
• the methods shown enable technical solutions which can be combined with known means of remote monitoring and which allow a maximum of operational security with minimal personnel expenditure.
