Definitions

  • the invention relates to a temperature control device according to a printing press the preamble of claim 1.
  • Such a temperature control device is known from EP-A-0 383 295. She has a four-way valve between flow and return. From DE-A-44 29 520 a temperature control device is known, for whose function an injector is required, which makes the device more expensive. Further Temperature control devices for printing presses are known from DE-A-23 60 611, DE-A-42 02 544 and DE-A 37 26 820 are known. Heat consumers to be tempered or cold consumers are printing press cylinders various types and fountain solution for wet offset printing.
  • the Tempering of the rolls or cylinders can be done by Bath fluid is passed through it or by the Bath fluid is passed through a heat exchanger which air is cooled, which is blown by a fan onto the outer surface of the relevant cylinder or the corresponding roller is blown.
  • the object of the invention is to achieve the temperature control device to train a printing press in such a way that it is inexpensive and Temperature of a consumer can be kept in extremely tight tolerances.
  • the invention is used in particular for cooling parts of the printing press, which, without such cooling, would reach temperature values above the temperature value required for an optimal printing process.
  • the invention is also suitable for heating Printing machine parts as long as they are still in a machine start-up phase have not reached their optimal operating temperature.
  • the temperature control device of a printing press shown in the drawing contains a temperature control fluid circuit 2, which contains a pump 4 and in which a consumer 6 of the printing press can be integrated.
  • the consumer 6 can be a cylinder or a roller or a part containing a liquid or be an electronic control circuit, within which the temperature within extremely narrow tolerances on a set point or should be kept in a setpoint range, for example a Temperature setpoint, which must not fluctuate more than +/- 0.25 ° C.
  • the tempering fluid circuit 2 is tempering fluid through the pump 4 in Direction of an arrow 8 circulates.
  • a thermal fluid source 10 is filled with thermal fluid and forms one Heat exchanger section in which a heat exchanger section 12 a Refrigerator 14 is located, through which refrigerant circulates.
  • the Refrigerator 14 may be of the type found in refrigerators and Freezers are known and compressed by a gaseous Refrigerant into a liquid refrigerant state and subsequent Expansion in which the refrigerant returns from the liquid state to the gaseous state passes, cold produces.
  • a fluid supply line 16 connects the temperature control fluid source 10 to a Inlet 18 in the temperature control fluid circuit 2 at one between the consumer 6 and the suction side 20 of the pump 4 located first connection point.
  • a fluid return line 22 connects an outlet 24 of the Tempering fluid circuit 2 at a second connection point between the Suction side 20 of the pump 4 and the consumer 6 with an inlet 26 Thermal fluid source 10.
  • controllable valve 28 preferably in Form of an electromagnetic proportional valve, which is arranged in Dependence on the actual temperature value of a temperature sensor 30 more or is opened or closed less widely.
  • the temperature sensor 30 is in the bath liquid circuit 2 between the Inlet 18 at the first connection point and the suction side 20 of the pump 4 arranged. It could also be in another place of the Bath fluid circuit can be arranged, however, have tests shown that at this point shown in the drawing faster and more precise temperature controls are possible.
  • a flow resistance 32 e.g. in the form of a flow orifice, is in Bath fluid circuit 2 between the inlet 18 of the first Junction and the outlet 24 of the second junction for generation of a dynamic pressure on its side facing the consumer 6 arranged.
  • An electronic control circuit 34 is functional with the temperature sensor 30 and the valve 28 connected and controls the valve 28 and thus his Fluid passage depending on that measured by the temperature sensor 30 Actual temperature value in order to maintain a temperature setpoint in the consumer preferably with the very narrow tolerance of +/- 0.25 ° C.
  • the temperature control fluid circuit 2 is a closed circuit. Also the Tempering fluid source 10 together with the fluid supply line 16 forms the Fluid return line 22 and the distance between them Temperature control fluid circuit 2, which contains the flow resistance 32, a closed cycle.
  • the temperature fluid circuit 2 is on its between the pressure side 38 of the Pump 4 and the consumer 6 section with a heater 40 Mistake.
  • the heater 40 is dependent on the actual temperature of the Temperature sensor 30 and the temperature setpoint of the consumer 6 from the Control circuit 34 can be activated. This allows the consumer 6 in the Start-up phase of the printing press if its temperature is still below its optimum operating temperature, i.e. below its temperature setpoint, are heated by the temperature control fluid of the temperature control fluid circuit 2. Before then the consumer 6 reaches its temperature setpoint, or at the latest when it reaches it, the heater 40 is turned off. If the Temperature setpoint, the valve 28 is activated instead of the heater 40 the tempering fluid circuit 2 via the inlet 18 cooled tempering fluid from the Supply tempering fluid source 10. This feed is because it is a closed system acts, at the same time via the valve 28 corresponding amount of tempering fluid from the tempering fluid circuit 2 Tempering fluid source 10 removed.
  • the temperature control fluid is preferred Water.
