AI Technical Summary

Problems solved by technology

Traditional and inexpensive ultrasonic generators cannot provide the required ultrasonic power
Conventional ultrasonic generators heat themselves very strongly due to the inefficiency of converting electrical power into useful ultrasonic power, which can lead to destruction of the sound source
Therefore, the hitherto proposals for improving the washing power of blanket washing units with the support of ultrasound could not be realized

Embodiment Construction

[0018] figure 1 A schematic view of a cylinder in a printing unit of an offset printing press is shown in a plane perpendicular to the axis of the cylinder. PLZ designates the so-called printing plate cylinder, on which the printing plate, not shown, inked by the rollers of the inking unit FW is fastened by holding devices in the clamping channel. The printed image on the plate is transferred as the cylinder rotates onto the blanket GT, which is tensioned on the blanket cylinder GTZ described below. PB denotes a sheet that passes between the blanket cylinder GTZ and the impression cylinder GDZ and is printed with ink by the blanket GT.

[0019] To wash the blankets, as usual in offset printing presses, a blanket washing device GTW is provided, which can be pressed onto the blanket cylinder GTZ along the arrow P when a printing job is changed after a printing run . The washing device GTW generally comprises a washing cloth 10 which is periodically unwound from a supply roll...

Abstract

A washing device has a washing cloth for removing contaminants, ink, etc. from a surface and an ultrasound device for assisting a cleaning operation. The washing device includes one or more ultrasound generators and one or more resonators each in the form of an oscillating flat metal body, from which sound energy is output onto a substantially linear region on the surface to be cleaned.

Description

technical field [0001] The invention relates to a washing device, preferably for cylinders in printing presses, with a washing cloth and an ultrasonic device for supporting the cleaning process. Background technique [0002] A washing device of this type is known, for example, from WO 03 / 011599. An ultrasound source is provided there to support the washing process, which is used in offset printing presses to remove dirt, ink, etc. more easily from the surface of the blanket stretched on the transfer cylinder. Furthermore, a cloth washing device for digital printing machines is described in DE 100 63 987 A1. There, in order to clean the cylinder carrying the printed image, a cleaning belt wetted with liquid is applied to the surface of the cylinder with ultrasonic actuators. Furthermore, DE 197 32 060 describes a washing device for blanket cylinders of offset printing presses, which has an ultrasonic generator but no washing cloth. Here, the loose dirt particles are scrape...
