Definitions

  • the invention relates to a printing press with an arrangement with tempering for the temperature control of dampening solution and / or printing cylinders, with at least one extending between the tempering and the printing press Temperierstoff Republic.
  • the operation of a printing press generates heat.
  • the heating not only detects the apparatus part, in particular the printing cylinder, but also the resources, in particular the fountain solution used in offset printing, which is often recycled and reused in a circulatory system. Warming above a certain level will degrade print quality. The position accuracy of the printed image may be affected.
  • dampening agents they also contain a not inconsiderable amount of alcohol, which evaporates relatively quickly at elevated temperatures. The composition of the fountain solution can therefore change relatively quickly so that it is outside a predetermined target range.
  • Printing presses are therefore often equipped with temperature control. These can be used both for the temperature control of the dampening solution and for the temperature control of the functionally essential parts of the printing press, in particular the impression cylinder. Tempering will usually mean cooling, but is also quite a heating into consideration, for example, in the start-up phase of a printing press.
  • a cooling water generator uses a refrigeration unit. To this end, the cooling water in a cooling water tank passes through a first pipe section by means of a pump and another pipe section via a three-way valve, in the cooling aggregate cooled and flows back into the cooling water tank. In winter, when the outside temperature is much cooler, the cooling unit is stopped and an air cooler takes over the task of temperature control. Here, the cooling water passes first again by means of the pump, the first line section. However, the three-way valve now switches to another line section of the air cooler, then the cooling water flows back into the cooling water tank.
  • the present invention has for its object to provide an arrangement on a printing machine of the above type, which allows to avoid unnecessary energy costs.
  • the arrangement according to the invention is characterized by an additional free-cooler temperature control, which has a flow of a temperature control heat exchanger, which is in the return of Temperierstoffsammlunges from the printing press to the temperature control and brought into heat exchange with the Temperierstoff réelle the temperature of the printing machine can be, wherein the temperature control medium is flowed through by the heat exchanger, which is the temperature control of the Temperierstoffnikes.
  • a free-cooler temperature control can be operated at low cost. This refers to a device that exploits the temperature of the ambient air, for example.
  • the free cooler temperature control unit is naturally only switched on when the achievable by this due to the outside temperature cooling temperature is below the desired target temperature of Temperierffennikes the tempering of the press. If this is the case, the intended cooling may possibly be achieved alone or at least in part by utilizing the outside temperature. If the outside temperature is equal to or higher than the desired tempering agent temperature in the tempering medium circuit of the printing press, the free-cooling temperature control unit is naturally switched off.
  • the heat exchanger of the freecooler temperature control is in the return of Temperierstoffnikes from the printing press to the tempering since in the return the temperature of the coolant tends to be higher than in the flow, so that here in a relatively large range of the outside temperature with the free cooler temperature control a cooling effect can be achieved can. This cooling effect must not be brought about in the actual tempering of the printing machine with much higher energy consumption.
  • the sole figure illustrates an alternative printing machine with an arrangement with temperature control, which is not the subject of the present invention.
  • a printing machine without a detailed representation is generally designated 10.
  • a tempering device 12 is assigned to this printing press 10.
  • a second connection between the printing press 10 and the tempering device 12 consists in a temperature control 20, which also has a flow 22 and a return 24 and is used to cool the apparatus part of the printing machine, in particular the impression cylinder.
  • a free cooler temperature control unit 26 is provided.
  • This free-cooler temperature control unit 26 has an air cooler 28 in which an impeller 30 can sweep outside air over a temperature control chamber 32.
  • This chamber 32 forms a Temperierstoffnik 34 together with a heat exchanger 36th
  • a valve 42 for example, a solenoid valve
  • a pump 44 is provided in the return.
  • the heat exchanger 36 is located in the Temperierstoff réelle 20, which serves to control the temperature of the dampening solution. As can be seen from the drawing, the heat exchanger 36 is arranged in the return line 24 of this Temperiersville Anlagenes 20. This arrangement has the advantage that the temperature in the return line 24 during cooling operation is higher than in the supply line 22, so that in many areas the cooling effect made possible by the outside temperature can be used. Moreover, no additional control means are required, since the tempering 12 is anyway adapted to take in the return temperature control different temperature and free to cool until a set temperature is reached again for the flow.
  • the heat exchanger 36 could also be used in the other tempering medium circuit 14. Both Temperiersville Ahmede 14,20 can be designed so that the heat exchanger 36 can be coupled via simple plug-in connections. In the warm season, the entire free cooler temperature control unit 26 may be omitted.
  • temperature sensor 46,48 In the return 24 of the Temperierstoffnike 20 and the flow 38 of the Temperierstoffnikes 34 are temperature sensor 46,48. If the flow temperature at the temperature sensor 48 is equal to or higher than the return temperature in the temperature sensor 46, the fan 30 is switched off via a control, the pump 44 is switched off and the valve 42 to prevent convection currents closed.
