Abstract
A cleaning device for printing machine cylinders and bearings (2, 60) for this for the rotatable mounting of a cloth spindle (4, 92) for a cleaning cloth. At least one of the bearings (2, 60) has a bearing bush (14, 64) which is provided with an external thread (16, 66) and which can therefore be screwed into an internal thread (17, 67) of a side part (20, 70).
Claims11
A cleaning device for printing machine cylinders, containing bearings (2, 60, 120, 160) for the rotatable mounting of a clean-cloth spindle (4) and of a dirty-cloth spindle (92), in each case at their spindle ends, in side parts (20, 70), in order to rewind a clean cleaning cloth (90) from the clean-cloth spindle (4) onto the driveable dirty-cloth spindle (92) and, on the path of cloth movement between the two spindles, to bring a cloth portion (95) into contact with a printing machine cylinder to be cleaned, characterized in that at least one of the bearings (2, 60, 120, 160) has a bearing bush (14, 64, 114, 164) which is provided with an external thread (16, 66, 116) and which can therefore be screwed into an internal thread (17, 67, 117) of the respective side part (20, 70), and in that an inner bearing part (6, 62, 119, 162), which is designed for receiving a spindle end to be carried by it, extends axially at least partially through the bearing bush and is positioned in the bearing bush.
The cleaning device as claimed in one of the preceding claims, characterized in that it is a structural unit which can be moved back and forth in a holding device (108), relative to the printing machine cylinder (97) to be cleaned, between a basic position, in which said structural unit is at a predetermined distance from the printing machine cylinder, and the cleaning position, in which a cloth portion (95) comes to bear against the printing machine cylinder to be cleaned.
The cleaning device as claimed in one of the preceding claims, characterized in that the bearing bush (14, 64, 114, 164) has an annular collar (22, 115) for coming to bear against and therefore for positioning at a side face of the side part (20, 70), the bearing bush being screwed into said side face.
A bearing for a cleaning device for printing machine cylinders as claimed in one of the preceding claims, characterized in that it is designed according to one of the preceding claims.
