Definitions
- the invention relates to a dryer device for drying printing ink, lacquers or similar coatings, with at least one in one
- Printing machine or the like built-in electrical emitter unit for irradiating printed sheets or web material.
- a large number of drying devices for the rapid drying of printing ink or the like are already known which, depending on the type of substance to be dried, use either the photochemical action of UV emitters or the thermal radiation of IR emitters or a combination of both. In any case, the dryer devices generate heat, including the UV lamps. Since the printing presses are becoming more and more compact, the dryer devices to be installed in the printing presses must also become more compact, which is increasingly causing problems with regard to the dissipation of the heat generated. From DE 42 44 003 AI a radiation dryer strip is therefore known, in which the rod-shaped IR radiator elements are cooled from the rear with cooling air which flows out from parallel rows of air discharge nozzles.
- the object of the invention is to provide a dryer device of the type mentioned, which causes the lowest possible heating of the surrounding machine parts at high drying power. According to the invention, this object is achieved in that the radiator unit has one or more fast-starting IR medium-wave radiators.
- the emitter unit Since the absorption ranges of common printing inks are in the medium-wave IR range, the emitter unit has a relatively good efficiency, since the drying effect of the medium-wave radiation is relatively high in relation to the total amount of heat emitted. In this way, a relatively low heating of the surrounding machine parts is obtained with a high drying capacity.
- the dryer device according to the invention is therefore suitable for installation in very compact printing presses in which the machine components mutually influence one another thermally. It is also suitable for printing presses that are very temperature sensitive due to the colors used, for example in waterless offset printing are. Furthermore, it can also be installed in printing presses in which, due to the use of certain detergents (eg type A2) with a low flash point of the solvent vapors, only considerably lower temperatures are permitted than in standard presses.
- certain detergents eg type A2
- the drying capacity is optimized in relation to the amount of heat given off to the surroundings if the radiation maximum of the medium wave radiator is in the wavelength range between 2 ⁇ m and 3 ⁇ m.
- IR carbon emitters in the emitter unit, a medium-wave radiation characteristic is obtained in a simple manner, with which very good efficiency can already be achieved.
- the efficiency of the emitter unit with carbon emitters can still be improved by the
- the emitter unit is operated during the irradiation process with an electrical power that is slightly reduced compared to the usual electrical power. With this measure, the maximum of the intensity distribution is further increased to the maximum
- the radiator unit In order to run through the area of the long-wave heat radiation, which is less effective for the drying effect, faster when switching on the radiator unit or when increasing the radiation power, it is recommended that the radiator unit can be operated briefly with increased electrical power in order to quickly increase the radiation power. In this way the Efficiency of the dryer unit improved on average over time, since the periods of less effective operating conditions are shortened.
- the dryer device comprises a power controller for regulating the radiation power of the emitter unit with at least one sensor for detecting at least one operating parameter which is dependent on the need or the effect of the radiation power, and that the power controller applies the radiation power as a function of the operating parameter (s) as required increasing the value required in each case and at least partially reducing it in the rest of the time.
- the radiation power of the emitter unit and / or its duration of action can be reduced to the minimum required value in each case, so that the product of the quantities mentioned, namely that emitted to the environment The amount of heat is limited to the lowest possible level from the outset.
- the heat release to the environment can be reduced without reducing the drying performance.
- Radiation power is fixed to the power controller. Even this limitation of the radiant power to the minimum value that is usually found to be sufficient for the individual case limits the total amount of heat emitted.
- the invention is further improved by the measure that at least one temperature sensor connected to the power controller is provided for detecting the temperature of the irradiated sheet or web material and that the power controller
- Radiation power is designed so that a predetermined temperature value can be set at least approximately. In this way, the radiation power required in each case can be automatically adapted to changing conditions, in particular different absorption properties of the material to be dried or changing ambient temperatures.
- At least one temperature sensor connected to the power controller for detecting the
- Temperature of certain areas of the printing machine is provided and that the power controller is designed to reduce the radiation power when a predetermined temperature value is exceeded. This measure prevents the printing press from being affected by overheating.
- the unnecessary release of heat to the environment can be reduced during the periods in which there is no material to be dried in the area of the radiator unit, in that one with the
- Power controller connected material sensor is provided for direct or indirect detection of the presence of sheet or web material in the area of the emitter unit and that the power controller on the radiation power in the presence of sheet or web material in the area of the emitter unit raising the required value and at least partially lowering in the absence.
- the emitter unit has an essentially flat reflector plate arranged behind the emitters, the heat radiation reflected by the material to be dried is reflected again and reflected back onto the material to be irradiated. This in turn increases the efficiency of the emitter unit, since the radiation reflected by the material is also not lost, but rather increases the radiation component effective in relation to the drying process.
- the reflector sheet is made of aluminum.
- a preferred development of the invention provides that air cooling is provided for the radiators, that the reflector plate is designed as a cover plate for a cooling air distribution strip and is equipped with perforated nozzles for passage of the cooling air to the radiators.
- the reflector plate in addition to its function as a reflector, also serves as a cover plate for the cooling air distribution shaft, which advantageously saves material and manufacturing costs and also reduces the installation space required and enables a more compact design.
- the air cooling improves the dissipation of the heat generated in the radiator unit and thus also enables a more compact design.
- the measure that the distances between adjacent perforated nozzles and / or the perforated diameters of the perforated nozzles are roughly adapted to the location-dependent air pressure distribution in the cooling air distribution strip, so that the radiators can be cooled as uniformly as possible everywhere, enables effective use of the available cooling air.
- This measure also has the advantage that air from the other areas of the printing press, which is usually dust-laden, cannot penetrate into the area of the radiator unit. So that the emitter unit is contaminated by dirt particles, in particular prevented by powder from a powder device of the printing press.
- the shielding plate can be provided with heat insulation on its side facing the radiator unit in order to reduce the heat transfer from the shielding plate to the machine parts.
- Figure 1 a dryer device according to the invention in a partially perspective view obliquely from above, partially schematic representation;
- FIG. 2 a radiator unit of the dryer device in a perspective view obliquely from below;
- Figure 3 a view of the underside of the same radiator unit.
- a lamp unit 1 of a dryer device which is provided for installation in a printing machine, not shown. It is a printing machine intended for waterless offset printing, which itself is relatively small and compact. Since the installation conditions in the printing press are very narrow, the emitter unit 1 is designed to be very compact and precisely adapted to the small installation space available. Due to its compact design and waterless offset printing technology, the printing press itself is very temperature sensitive. There is also the fact that it can only be cleaned with a type A2 detergent with a low flash point. Because of the resulting sensitivity to emissions of solvent vapors, only considerably lower temperatures are permitted than in standard printing presses.
- the dryer device emits as little heat as possible to the printing press.
- This problem is solved by the invention on the one hand by generating as little heat as possible, and on the other hand by preventing the heat generated by the radiator unit 1 from penetrating into other areas of the printing press and dissipating the heat quickly and effectively.
- the emitter unit 1 is provided for the irradiation of printed sheets 2 which run through the printing press and are guided past the emitter unit 1 below it. As can be seen in the schematic representation of Figure 1, belong to
- Dryer device a power controller 3, a Temperature sensor 4 for detecting the temperature prevailing on the sheet 2 and a temperature sensor 5 for measuring the temperature of the printing press at a point which is particularly sensitive to overheating.
- the temperature sensors 4, 5 are connected via signal lines 6, 7 to the power regulator 3, which in turn regulates the electrical power reaching the radiator unit 1 via a supply line 8 and a plug connection 9.
- a material sensor 10 is also connected to the power controller 3 via a signal line 11. With the aid of the material sensor 10 it can be recognized whether or not there are sheets 2 to be irradiated in the region of the radiator unit 1.
- the material sensor 10 can be designed, for example, as a light barrier, motion detector or simple electrical contact, or the required signal is derived from sensors of the printing press that are already present or from their operating states, for example from the supply voltage of motors or other electrical components.
- the sensors 4, 5, 10 thus detect parameters of the printing press.
- the material sensor 11 reports the radiation requirement when the material to be irradiated reaches the area of the radiator unit 1.
- the temperature sensor 4 can signal a higher or lower radiation requirement depending on the temperature of the material to be irradiated.
- the temperature sensor 5 indicates when the radiation power has led to an inadmissible heating of sensitive printing machine parts. In any case there is a need for regulation and the power regulator then regulates the electrical power flowing into the emitter unit 1 and thus the emitted radiation power up or down, in accordance with predetermined control mechanisms, preferably by means of a programmable microprocessor.
- the amount of heat emitted by the radiator unit 1 can be reduced at least on average over time without falling below the minimum radiation power required for the irradiation.
- the ratio of usable radiation quantity to the total amount of heat emitted is increased at least on average over time, and the efficiency of the drying device defined in this way is improved.
- the radiator unit 1 is equipped with four carbon radiator tubes 12, which are only indicated by dashed lines in FIG. 3. These are quartz tubes, in each of which an approximately 1 cm wide carbon band is arranged. The tube ends are closed and provided with electrical contacts, via which a current flow through the carbon band can be established. As a rule, the quartz tubes are provided with a gold vapor deposition on one side, which is arranged as the rear during operation, which reduces the emission of IR radiation to the rear.
- Carbon emitters are particularly well suited for the IR drying of the printing inks used here because the maximum of their radiation spectrum lies in the medium-wave infrared range and thus the essential ones
- the carbon radiators 12 are fastened in special holders 13, 14 to a cooling air distribution strip 16 and arranged transversely to the conveying direction of the material 2 to be irradiated.
- the carbon radiators 12 are connected to a connecting cable 15, which ends in a plug connection 9 that can be connected to the supply line 8.
- the cooling air distribution strip 16 consists essentially of an approximately cuboid metal box, which is arranged above the carbon radiator 12 and connected to a somewhat smaller, also box-shaped prechamber 17. Between the antechamber 17 and the
- Cooling air distribution strip 16 are provided holes, not shown, for the passage of cooling air.
- the cooling air comes from a blower, not shown, and passes through two feed pipes 18, 19 opening into the prechamber 17 at different points in the prechamber 17, where it is distributed and flows into the cooling air distribution strip 16 via the holes (not shown).
- the underside of the cooling air distribution strip 16 is closed with a cover plate 20 made of aluminum, which serves on the one hand as a reflector for the IR radiation reflected by the irradiated material 2 and on the other hand as a carrier for a plurality of perforated nozzles 21 which are intended for the passage of the cooling air.
- the cooling air emerges from the perforated nozzles 21 and strikes the carbon radiators 12, which are thus cooled.
- the perforated nozzles 21 are arranged in four rows along the carbon emitters 12. Within a row, the distances between the perforated nozzles 21 are smallest in the areas where within the
- Cooling air distribution bar 16 has the lowest air pressure. In areas with higher air pressure, the perforated nozzles 21 have larger distances. This creates a compensation, so that the carbon radiators 12 are flowed around over their entire length essentially by the same amount of air and evenly cooled.
- a suction device not shown, which is supported by air baffles, also not shown.
- a shielding plate (not shown) for shielding the neighboring machine parts from the Heat radiation is provided, which is additionally provided with heat insulation on its side facing away from the heat radiation.
- An air gap 22, 23 is arranged on the cooling air distribution bar 16 with respect to the direction of movement 24 of the irradiated material 2 before and after the radiator unit 1.
- the air gaps 22, 23 extend across the entire dimension of the emitter unit 1 and thus each produce a closed air curtain, through which the area of the emitter unit 1 is partitioned off in such a way that neither hot air into other areas of the printing press nor contamination, in particular powder from a Powder station, or combustible solvent vapors from other areas of the printing press can reach the area of the radiator unit 1.
- Radiator unit 1 has numerous advantages, in particular simple handling for service and maintenance, a small space requirement, durability, simple installation and easy retrofitting. LIST OF REFERENCE NUMBERS
