Definitions
- the invention relates to a temperature control device for setting and maintaining the temperature of the dampening solution in offset printing presses with one or more dampening and printing units or inking units, the cooled dampening solution being removed from a dampening solution storage container and fed to a setpoint temperature via inflow lines and fed to and from a dampening unit box is removed from a dampening solution lifter and transferred by means of dampening rollers, which dampening unit box is connected to the dampening solution storage container via a return flow line.
- Such a temperature control device is known from DE-AS 1 191 833.
- the dampening solution is cooled to a temperature of about 2 to 10 ° C and transferred by means of dampening rollers of the dampening unit.
- the dampening solution cooled by means of a cooling unit is removed directly from a dampening solution storage container and fed via an inflow line to the dampening unit box, which is connected to the dampening solution storage container via an overflow and a return flow line, so that overflowing dampening solution can flow into the dampening solution storage container.
- the dampening solution is removed from the dampening unit box in the form of a roller by means of a dampening solution lifter and transferred to the pressure roller in a manner known per se via further rollers interacting therewith.
- the dampening solution reservoir, inflow and return flow lines are thermally insulated to prevent heating of the dampening solution in the circuit via the piping system.
- the temperature control device reduces the dampening solution consumption and considerably lowers the emulsification factor due to the low temperature to be used.
- the cooled fountain solution partially slows down the temperature increase of the ink during printing, which counteracts the emulsion and also keeps the physical properties of the ink constant. In addition, an undesirable condensation cannot occur with the small amount of water reaching the pressure plate, because the temperature of the pressure plate is not sufficiently reduced as a result.
- a fountain solution center in which fountain solution is removed from a treatment plant with a reservoir and fed to the dampening units via a feed line system by means of a pump .
- the fountain solution flows from the dampening units into liquid containers and from there back into the treatment plant.
- the dampening water in the reservoir is constantly cooled by a cooling unit to a certain temperature via a cooling circuit.
- the cooled fountain solution is in turn fed to the dampening units.
- This system does not allow fine regulation and individual regulation of the temperature of the fountain water in the dampening units, but is dependent on the temperature which the fountain water takes up in the reservoir of the treatment plant.
- the principle of offset printing is based on the correct ratio of printing inks and dampening solution content on the printing plate, whereby only the image-carrying areas of the printing plate are wetted with printing ink.
- the required amount of ink is precisely metered in zones, as is the corresponding amount of dampening solution. What amount of dampening solution is required depends on the type of preparation and composition, its supply and temperature, but also on the physical properties of the printing ink used, the quality of the printing material or printing paper and on the environmental factors of the printing area.
- the dampening unit which is in direct contact with the printing unit via the dampening rollers, also heats up during production. The rise in temperature affects the rheological properties of the printing inks.
- the circulating dampening solution is warmed up as the temperature increases while the machine is running. This leads to faster evaporation of the dampening solution on the rollers and the plate.
- the higher evaporation of the dampening solution is compensated by an increased dampening solution guidance, which prevents toning and smearing.
- the printer compensates for the drop in solid ink density by increasing the color guide.
- the alcohol content or the alcohol substitute content of the dampening solution must be increased continuously.
- extraction devices must be installed in order to be able to extract the alcohol vapors and other vapors from chemical additives.
- Motor-controlled multi-way mixers such as three-way and four-way mixers, are known in control systems of central heating systems in a wide variety of constructional forms. With all mixers, part of the returning heating water is removed from the return of the heating system and added to the hot heating water coming from the boiler system in order to reach a temperature of the heating water in the flow which corresponds to the z. B. existing outside temperature, outside the building, is adjusted to allow a uniform heating of the room, but also a quick heating by appropriate setting.
- Such a mixer actuator is known from DE 32 07 427 C2 and has a cylindrical mixing chamber with a rotatable mixing flap which is connected to a motor via a drive shaft.
- a cylindrical bypass chamber is provided axially next to the mixing chamber, with openings opening into the return and the heating flow.
- the bypass actuator is a rotary valve connected to the drive shaft in a rotationally fixed manner, the angular position of which can be preset with respect to the mixing flap.
- Mixers have the advantage that fast temperature control is possible on the one hand through the position of the mixing flap and on the other hand fine regulation of the flow is possible through the mixing ratio.
- the machine For multi-color printing, depending on the color printing, two, three, four or five identical lines are usually arranged in series, one after the other.
- the machine In four-color printing, the machine consists of four arrangements for printing out the colors: yellow, magenta, cyan and black or yellow, red, blue and black. Since all colors have different physical properties, the inking unit temperature control must take these properties into account. Adjusted to this, it is necessary that the dampening solution is kept at different temperatures in the individual dampening units of the machine arrangement.
- a temperature control device for the inking unit temperature control of offset printing machines in which a closed Temperature control circuit is provided via a motor-controlled multi-way mixer, which is controlled depending on the target specification and the temperatures determined on the surface of a roller of the inking unit as well as the determined flow and return temperature in the inflow and return flow lines so that no sudden temperature changes occur and on a constant surface temperature of the ink roller is regulated, which is equivalent to the ink temperature.

- the invention can be used as a single system for tempering a dampening unit of a single offset printing press.
- temperature control devices designed according to the invention can be used for each of these systems, which operate independently of one another. This applies both to the mechanical arrangements, such as inflow and return line, dampening solution storage tank, cooling unit and possibly pump arrangements, as well as to the electronic control by means of the control unit.

- the dampening unit box is coupled with the overflow to a return flow line, which is connected to the return flow line in the first partial circuit.
- the control device must be designed so that on the one hand the mixer device and on the other hand the individual valves are controlled by it. This is easily possible by reprogramming the program accordingly or by expanding the program and the acquisition and control systems.

- the admixture from the return flow ie from the return flow line into the inflow line of the first sub-circuit, takes place via a connecting line which opens into the inflow line.
- the circulation speed in the first subcircuit can be increased or decreased in a speed-controlled manner by means of a circulation pump, so that additional fine regulation is also possible in this way.
- the dampening solution temperature in the individual sub-circuits is determined separately and recorded as a disturbance variable by the control unit and taken into account when determining the control variable.
- the corresponding software program must enable these disturbances to be processed.
- Claim 7 generally provides that speed-controlled circulation pumps are provided for changing the flow rate of the dampening solution. This has the additional advantage that, in the case of particularly long inflow and return flow lines, heating through the long lines is largely avoided and more precise regulation is made possible.
- the temperature of a roller which transfers or distributes the ink is taken into account as a further disturbance variable, so that the temperature of the dampening solution is optimal respective color and the processing temperature of the color is customizable.
- the color density, room temperature, air humidity, alcohol content or proportion of the Alcohol substitute in the fountain solution, the color processing factors and the paper constant are taken into account.

- the display can be alphanumeric or graphical, so that the printer can get an overview of the operating status of the individual printing and dampening units of the system during operation.
- the temperature control device has the advantage that fine regulation of the dampening solution is possible up to orders of magnitude of ⁇ 0.3 ° C, which enables an optimal adaptation of the temperature of the temperature control agent to the temperature of the printing ink, so that a high print quality can be achieved .

If such a temperature control device is used in a machine in which, according to the same principle, the temperature control of the inking unit takes place, as is stated in the older patent application P 39 04 854, it is achieved that the print quality remains unchanged even after hours of operation of the printing device compared to the First printing is achieved.
- the temperature control device makes it possible to keep the percentage of alcohol in the dampening solution or an alcohol substitute very low compared to conventional systems, so that harmful vapors only escape from the machines to a limited extent, so that particularly complex suction devices do not have to be provided.
- an almost closed first partial circuit in which only a small amount of dampening solution is added via mixer devices, enables the dampening solution to be quickly adapted to the desired temperature.
- the control unit carry out an inlet and outlet control according to a dampening solution temperature curve.

B. to quickly reach the desired target temperature while starting the machine.
- the return flow line of the first partial circuit does not need to flow directly into that of the second.
- reservoirs, filters and, if necessary, expansion tanks can be interposed. It is advisable to insulate these system components, as well as the other parts of the temperature control device, so that outside temperatures do not have any noticeable effects on the temperature of the temperature control medium in the flow or return.
- an advantageous embodiment of the invention provides that a control circuit is provided in the control unit, which determines a control variable for the cooling unit as a function of the temperature of the dampening solution in the dampening solution reservoir and the specification of the lowest setpoint value of the temperature of the dampening solution in the flow of the first partial circuit .
