Abstract
In a rotary printing machine, in particular a web-fed rotary printing machine, having at least one printing unit including a plurality of printing-unit cylinders, of which at least one can be brought into and out of operative connection with at least one functional unit which is associated with a function needed to operate the printing unit, is provided with a drive device and is fitted on a linear guide device, a high level of operating convenience and working accuracy being achieved by the functional unit being assigned a positioning device, which has a controller which can be fed with at least one position-dependent signal which can be generated by means of a sensor arrangement associated with the functional unit and by which the drive device can be controlled.
Claims19
A rotary printing machine, comprising:
- a printing unit including a plurality of printing-unit cylinders;
- a functional unit associated with a function needed to operate the printing unit,
- a linear guide device on which said functional unit is fitted for movement in a linear direction with respect to one printing-unit cylinder of said plurality of printing-unit cylinders;
- a drive device for moving said functional unit on said linear guide device such that said functional unit and said one printing-unit cylinder are relatively movable into and out of connection with one another;
- a sensor arrangement associated with each said functional unit for generating a position-dependent signal;
- and
- a positioning device associated with said functional unit and including a controller, said controller controlling said drive device responsive to said position-dependent signal, wherein said sensor arrangement includes a sensor operative for sensing a functional unit travel distance when said drive device is activated and outputting a sensed travel distance signal to said controller, and another sensor for sensing a travel encounter of said functional unit with said one printing-unit cylinder and outputting an encounter signal to said controller.
A rotary printing machine, comprising:
- a printing unit including a plurality of printing-unit cylinders;
- at least one functional unit associated with a function needed to operate the printing unit;
- a linear guide device on which said at least one functional unit is fitted for movement in a linear direction with respect to at least one of said printing-unit cylinders;
- a drive device for moving said functional unit on said linear guide device such that said at least one functional unit and said at least one of said printing-unit cylinders are relatively movable into and out of connection with one another;
- a sensor arrangement associated with each said functional unit for generating a position-dependent signal;
- and
- a positioning device associated with said at least one functional unit and including a controller, said controller controlling said drive device responsive to said position-dependent signal, wherein said sensor arrangement includes a sensor for sensing a travel encounter of said functional unit with said one printing-unit cylinder, said sensor being operative to output a signal to said controller which is indicative of a contact pressure between said functional unit and said one printing-unit cylinder.
