- the output can be increased to up to 10 watts / 1 liquid medium in the cleaning tub.
- the cleaning result can be further improved if the ultrasonic waves are directed onto the washing device from at least two directions.
- the ultrasonic waves heat the liquid medium.
- one embodiment of the method according to the invention provides for the liquid medium to be cooled in the cleaning trough.
- the washing device is introduced into the cleaning trough by means of a washware carrier, for example a wire basket.
- the washing device is removed from the cleaning trough, optionally with the aid of the cleaning product carrier, dried and put back into the offset printing machine. If the cleaning process cannot be carried out in an operational downtime that is required anyway Perform offset rotary machine, an identical blanket washing device can be kept as a replacement.
- a cleaning device for carrying out the method is characterized in that at least one ultrasound head is arranged on the cleaning trough and the cleaning device has a rinsing system for connection to each spray bar.
- Each ultrasound head can be designed, for example, as a submersible transducer, vibrating plate or cylindrical vibrator.
- the ultrasonic heads are attached to the cleaning trough by means of hanging hooks, fastening straps or directly to a wall of the cleaning trough by means of screw connections or welds.
- the cleaning tub can have, for example, internal dimensions (length x width x height) of 1200 x 300 x 300 mm.
- the cleaning device has at least two ultrasonic heads on opposite side walls of the cleaning tub.
- the intensity and duration of action of the ultrasonic waves can be set if the ultrasonic generators are connected to a power control and / or a timer.
- Level monitoring for the liquid medium prevents the ultrasonic heads and the existing pumps from running dry.
- Pumps are arranged in the cleaning device for rinsing the spray rods, but also for automated filling and filling of the cleaning device with liquid medium.
