Cleaner for Dispense Needles - WIPER
Automated cleaning of dispensing tips and nozzles using a textile ribbon.
Cleans flat nozzles at contact (Wiper I) or dispensing tips after start trigger (Wiper II). The ribbon moves on after the cleaning so that a new part of the ribbon is available for the next cleaning. Digital I/Os and various configuration options allow for an easy integration into higher-level systems.
- Wiper I cleans soiled jet valve nozzles.
On the upper side of the cleaning station a cleaning tape rests lightly on a push button. When the valve nozzle triggers the push button there is mechanical contact. The tape is then pulled under the nozzle and any residue on the nozzle is removed.
- Wiper II cleans soiled dispensing tips.
On the top of the cleaning device there is a gripper mechanism with flexible gripper jaws which are covered by a cleaning tape. The soiled dispensing tip is inserted into the space between the jaws and the gripper closes and presses the tape around the tip. When the tip exits the grippers, any residue on it is wiped clean.
As there are two sizes of gripper jaw available, even the shortest tips can be effectively cleaned.
- Wiper V(ision) assists in recording the exact dosing position in dispensers.
A textile, paper or transparent PE tape, which can be lit from underneath if required, runs across the top of the station. Dispense dots applied to the tape can be measured by a higher-level machine controller and used to calculate and correct the position, for example. After measurement the tape is spooled forwards to ensure that the surface is clean for the next measurement.
