Definitions

  • the present invention relates to an apparatus and a method for controlling the temperature of a body of revolution, i. in particular for tempering a cylinder, e.g. a blanket cylinder of a printing press.
  • rolling two cylinders together can cause local heating.
  • this may be the case with a rubber blanket fitted with a blanket or rubber sleeve, which rolls on a plate cylinder.
  • the local heat input takes place in particular in the contact region of the blanket cylinder with the channel of the plate cylinder.
  • the phenomenon of local heat input is referred to as a hot-spot problem, which can be adjusted to each other even in rubber cylinder / rubber cylinder pressure units in the contact area of the rubber cylinder.
  • a rotary body e.g. a cylinder and in particular a blanket cylinder, provided for a printing press, wherein the rotary body has at least one opening.
  • the opening may be formed, for example, as a subsequently introduced into the cylinder bore.
  • the bore is provided substantially in the axial direction of the rotary body and preferably coaxially with the rotary body. The bore serves to guide a fluid for tempering the rotary body in the rotary body and also to derive again from the rotary body.
  • a supply line with at least one inlet opening in the interior of the rotary body is provided in the bore.
  • the fluid flows to temper in the rotary body and from the intended inlet opening, the fluid flows through the gap between the bore and feed line, i. on the inner surface of the bore again out of the body of revolution.
  • the bore in the rotary body or cylinder can pass completely through the rotary body, in which case one end of the bore must again be closed with a corresponding closure, and on the other hand, the bore can be designed in this way be that it does not go completely through the body of revolution. That is, the drilling depth adapted to the cylinder provides the closure at the second end of the cylinder.
  • connection piece on an end face of the rotation body i. in the case of a rubber cylinder at the base of the blanket cylinder, provide both an inlet and outlet.
  • the fitting itself does not rotate and the rotation body is rotatably attached to the fitting.
  • Temperature-controlled fluid of a tempering device enters the rotating body via the connecting piece.
  • At least one spacer is provided between the feed line and the inner wall of the bore.
  • the supply line may be mounted in the bore, however, it is also possible to rotatably support the supply line in the connecting piece, so that no spacers must be provided or the manufacturing accuracy of the spacers may be lower.
  • the spacers may be provided with flow areas, i. Openings in the spacer, be formed.
  • a different structure can be chosen, so that the use of a supply line is only optional. If, in fact, the bore is guided completely through the rotation body, then it becomes possible to introduce the fluid onto a first side of the rotation body and to let the fluid escape again on a second side of the rotation body. This makes it necessary to use two fittings, i. to provide one connecting piece per end of the rotary body, which in turn allow a relative movement between the rotary body and connector.
  • the surface on the inner wall of the bore is increased to the Heat transfer to the rotating body too improve.
  • a surface enlarging means a component can be provided in the bore, which divides the fluid into numerous individual flows, which then flow over the enlarged surface of the component.
  • the surface enlarging means and the flow rate retarding means may be accomplished both as a separate component and as a change in the surface finish of the bore made by a machining step on the bore.
  • a tempering device in addition to or instead of the tempering device customary in printing presses, can be provided in the immediate vicinity of the rotation body.
  • a tempering device in the vicinity of the rotation body makes it possible to reduce the dead time for heating up the rotation body.
  • the additional tempering device can be connected, for example, to a line of the temperature control system for the printing press, which leads to the body of heat to be heated.
  • the additional tempering device may be, for example, an electrical heat exchanger, which is designed for example as a water heater. Further, it is possible to install this water heater parallel to the supply line of the Druckmaschinentempermaschinessystems to the rotary body, so that operation with and without water heater is possible.
  • the object of the invention can also be achieved by a method according to the invention for controlling the temperature of a rotational body of a printing press.
  • the printing press has rotational bodies rolling against one another and a tempering device for heating at least one rotational body.
  • heat is generated by the rolling of the rotating bodies against each other on the surface of the heatable rotating body and, in the worst case, only a part of the surface of the heatable rotating body is heated to a first temperature.
  • Process step of the heating of the rotating body is the one-sided heat input at the surface, ie the so-called hot-spot formation compensated.
  • the introduced by the temperature control in the rotational body temperature must be at least as high as the temperature at the surface of the rotating body.
  • the heating of the rotating body is preferably carried out before the start of printing or before putting other parts of the printing machine.
  • the device according to the invention can advantageously be based on a conventional cylinder construction. That is, since a bore can be introduced into a conventional cylinder, no multi-part cylinder is necessary, but a conventional cylinder can be redesigned as part of a retrofit.
  • Figure 1 shows a cross-sectional view of a blanket cylinder 1, which is provided with a through hole 2.
  • a feed line 3 is mounted on spacers 7.
  • the spacers 7 have flow areas 6, which are formed here as circular bores in the circumferential direction of the spacer 7.
  • a gap 4 is formed between the inner wall of the bore 2 and the supply line.
  • the supply line 3 is rotatably connected to the connector 5, which is fixedly arranged on a base surface of the blanket cylinder.
  • a closing means 8 for closing one side of the bore is provided on the base part of the blanket cylinder facing away from the connecting piece.
  • an additional temperature control device 9 is provided parallel to the temperature control line 12.
  • a heated fluid flows through the temperature control line 12 via the connecting piece 5 into the feed line 3.
  • the feed line 3 has at least one inlet opening, preferably at the end of the feed line. In addition, numerous openings may be provided in the circumferential direction of the supply line.
  • the fluid for temperature control flows back in the space between the inlet 3 and bore 2 to the connector 5 and is there via suitable connection lines (not shown) dissipated.
  • the piping designed as a feed line in this embodiment could also serve as a drain, so that the flow direction would be exactly the reverse of the embodiment explained here.
  • Figure 2 shows a blanket cylinder 1 with a bore 2, which penetrates the blanket cylinder in its entire width.
  • a connecting piece 10 is provided, through which the fluid flowing in via the connecting piece 5 flows away again.
  • the connecting pieces 5 and 10 are mounted stationary and the blanket cylinder 1 is rotatably mounted therebetween.
  • a surface enlarging agent 11 is disposed in the bore 2.
  • the component 11 has an inner Lamellar structure with the largest possible surface on its outer periphery, so that the heat transfer from the fluid to the cylinder is optimized.
  • FIG. 3 shows a blanket cylinder having a construction which can also be used for the method according to the invention.
  • the blanket cylinder shown in Figure 3 is heated by a tempering device.
  • the blanket cylinder is heated to a temperature greater than or equal to the introduced due to the hot-spot formation temperature, which can also be done before the start of printing.
  • Figure 3 shows a device that can be used for the inventive method, namely a rubber cylinder with inlet and outlet, ie several holes that serve as a supply or discharge.
  • thermal energy can be released by means of heat conduction and / or thermal radiation and / or convection to an inner surface of a rotation body for realizing the method according to the invention.
  • a heat transfer to the inner surface of the rotating body is not mandatory, but it is also possible to heat the outer surface of the rotating body.
  • a tempering device can also be provided as a heating element in the rotary body.
