Definitions
- the invention relates to a method for influencing a printing ink and an existing dampening solution emulsion in a printing press and for implementation printing presses suitable for the process.
- WO 91/18744 describes a method for removing gas bubbles in a printing ink used for flexographic or gravure printing, in which Ultrasound energy is directed into the printing ink and in this way foaming is reduced.
- the ultrasonic energy can be anilox or gravure rollers, Ink tanks or chambered doctor blades of the printing ink equipped with ultrasonic actuators be fed.
- Yet another example of the use of ultrasonic waves in printing machines is a method for controlling the water content described in JP-HEI 3-90359 a printing ink emulsion of an inking unit.
- an in a water splitting device arranged ultrasonic vibrators Ink emulsion separated on the one hand in printing ink and on the other hand in water. During the separation, the ink emulsion is not on any roller of the Inking unit, but in the water elimination device.
- a metering device for a liquid medium described in which the medium vibrates by means of a vibration element is transferred.
- the vibrating element can be applied to the surface of a scoop roller acting ultrasound transmitter.
- the medium is either lacquer or Fountain solution and in no case one from a printing ink and a fountain solution existing emulsion.
- the invention is based on the object of specifying a method by which will improve print quality, and at least one for performing the Process suitable press to create.
- the object is achieved by a method having the features of claim 1, by a printing press with the features of claim 7 and by a Printing machine with the features of claim 12 solved.
- the invention is based on the knowledge that under the condition that the Emulsion as a thin emulsion film on a peripheral surface of the roller is an emulsification by means of the vibrating with the ultrasonic frequency Vibration exciter can be transported. This finding is in stark contrast to the method known from JP-Hei 3-90359, in which a means of ultrasound Demulsification should be promoted.
- a printing press according to the invention with a one of a printing ink and a Dampening solution existing emulsion leading roller is characterized in that the Roll a vibrating and corresponding with an ultrasound Frequency of vibrating vibration exciter is assigned.
- One or more such an inking unit comprising rollers which are excited to vibrate requires a total of fewer rollers than a conventional inking unit to process the printing ink.
- Another printing machine with a one of a printing ink and A roller carrying an emulsion containing an fountain solution is characterized by that in addition to the roller, at least one ultrasound source directed onto the roller is arranged.
- the ultrasonic waves of the ultrasound source which on the emulsion on the hitting the rotating roller, the emulsification is also improved.
- Banded Emulsion disorders are eliminated by the ultrasonic waves even before the Emulsion disturbances in a manner similar to stenciling from the roller in one other roller or a printing form can be transferred.
- Printing form 3 is a planographic printing form (Planographic Printing Form) for offset printing.
- the rubber-covered, soft-elastic roller 4 and one the latter frictionally driving roller 5 are components of a section shown only Inking unit 6 of the printing press 1.
- the latter contains 3 for moistening the printing form dampening system consisting of rollers, which is of a known type and therefore not needs to be represented.
- the chrome-plated, hard roller 5 is an axially iridescent Friction roller.
- the roller 4 Seen in the direction of rotation of the printing form cylinder 2, the roller 4 is the last roller of the Inking unit 6 in front of a blanket cylinder 7 on the printing form 3.
- One of the roller 4 assigned and designed as an ultrasound source 8 vibration exciter Printing machine 1 is focused on a peripheral region of the roller 4, which in Direction of rotation of the roller 4 seen a common contact line of the rollers 4 and 5th downstream and a common contact line 10 of the roller 4 and the printing plate 3rd is upstream.
- the contact line 9 is a liquid acceptance line and the Contact line 10 a liquid discharge line of the roller 4.
- the ultrasound source 8 is off Piezo elements 11, 12, 13 assembled and extends over the one film-shaped ink fountain solution emulsion 14 covered axial length of the roller 4th
- the function of the ultrasound source 8 is as follows: One during the rolling of the rollers 4 and 5 and z. B. caused by rolling over a cylinder channel 15 of the printing form cylinder 2 shock can lead to a strip-shaped and parallel to the contact line 9 emulsion disturbance 16 within the otherwise undisturbed emulsion 14. When the roller 4 enters the cylinder channel 15, the pressure and the slip between the rollers 4 and 5 abruptly decrease in the area of the contact line 9. When the roller 4 exits the cylinder channel 15, the pressure and the slip suddenly increase again.
- the pressure and the slip, ie the peripheral surface speed ratio, between the rollers 4 and 5 are variables influencing the emulsification of the printing ink and the dampening agent on the roller 4, the sudden changes of which cause the emulsion disturbance 16.
- focused ultrasonic waves 16, 17, 18 of the ultrasound source 8 In order to homogenize the disturbed emulsion 14 as far as possible and to reduce the conspicuousness of the emulsion disturbance 15 in the printed image, focused ultrasonic waves 16, 17, 18 of the ultrasound source 8 not only remove the emulsion disturbance 15 but the entire film surface of the emulsion 14 treated in the course of their transport past the ultrasound source 8. The incident ultrasonic waves 16, 17, 18 cause the roller 4 and on it the emulsion 14 to vibrate, the frequency of which is in the typical range for ultrasound.
- the dampening solution and the printing ink which are strongly demulsified by the impact in the region of the emulsion disturbance 15, quickly emulsify again.
- the emulsion disturbance 16 is eliminated before it reaches the contact line 10 and can be transferred to the printing form 3.
- the intensity of the ultrasound waves 16, 17, 18 can be varied by appropriate setting of the ultrasound source 8. Depending on the setting of the intensity, different degrees of emulsification of the emulsion 14 can be set on the roller 4.
- the roller 4 caused by the ultrasonic waves 16, 17, 18 in micro-vibrations relative to the roller 5 causes regular micro-disturbances of the emulsion 14.
- the "micro-disturbances" which are deliberately generated and permanently caused during printing overlap the unwanted and much stronger emulsion disturbance 16, so that it is hardly noticeable in the printed image if the use of the ultrasound source 8 does not succeed in completely eliminating the emulsion disturbance 16 before it is transferred to the printing form 3.
- FIG. 2 shows that the roller 4 vibrates in an ultrasound is assigned to the corresponding frequency offset further vibration exciter 21, the z. B. can be switched on instead of the ultrasound source 8.
- the Roller 4 in a multi-part design from a roller axis 22 and one by means of a Slide bushing 23 rotatably and axially displaceably mounted on the roller axis 22 Roller sleeve 24 is made.
- the vibration exciter designed as a piezo element is supported on one side on the roller axis 22 and can also on another part fixed to the frame.
- the vibration exciter presses with its other side on a side surface of the roller sleeve 24 and a transition into this side surface Side surface of the sliding bushing 23 Vibration exciter 21 set in an ultrasonic vibration, which the Vibration exciter 21 on its side abutting the roller sleeve 21 on the Roller sleeve 24 transmits, so that this micro vibrations in the axial directions the roller 4 can be forced with a frequency corresponding to ultrasound.
- This axial micro-vibrations improves the emulsifying behavior of the emulsion 14 not only in the area of the emulsion disorder 16, but throughout Circumferential surface of the roller sleeve 24.
- roller 4 in addition to Roller 4 is another roller, preferably another inking roller, or more Rollers, preferably other inking rollers, the inking unit 6 with a Vibration exciter 21 structurally and functionally corresponding vibration exciter is or are equipped.
- a dampening roller of the type already mentioned can also be used Dampening unit with a vibration exciter corresponding to the vibration exciter 21 be equipped.

Abstract
Description
- Figur 1
- ein erstes Ausführungsbeispiel, mit einer Walze und einem von der Walze separat angeordneten Schwingungserreger und
- Figur 2
- ein zweites Ausführungsbeispiel mit einem in der Walze angeordneten Schwingungserreger.
Eine während des aufeinander Abrollens der Walzen 4 und 5 und z. B. durch das Überrollen eines Zylinderkanals 15 des Druckformzylinders 2 verursachter Stoß kann zu einer streifenförmigen und parallel zur Kontaktlinie 9 verlaufenden Emulsionsstörung 16 innerhalb der ansonsten ungestörten Emulsion 14 führen. Beim Eintritt der Walze 4 in den Zylinderkanal 15 verringern sich schlagartig die Pressung und der Schlupf zwischen den Walzen 4 und 5 im Bereich der Kontaktlinie 9. Beim Austritt der Walze 4 aus dem Zylinderkanal 15 erhöhen sich die Pressung und der Schlupf schlagartig wieder. Die Pressung und der Schlupf, d. h. das Umfangsoberflächengeschwindigkeitsverhältnis, zwischen den Walzen 4 und 5 sind das Emulgieren der Druckfarbe und des Feuchmittels auf der Walze 4 beeinflussende Größen, durch deren schlagartige Änderungen die Emulsionsstörung 16 hervorgerufen wird. Um die gestörte Emulsion 14 zu homogenisieren, so weit dies möglich ist, und die Auffälligkeit der Emulsionsstörung 15 im Druckbild zu verringern, wird mittels fokussierter Ultraschallwellen 16, 17, 18 der Ultraschallquelle 8 nicht nur die Emulsionsstörung 15, sondern die gesamte Filmoberfläche der Emulsion 14 im Laufe von deren Vorbeitransport an der Ultraschallquelle 8 behandelt. Durch die auftreffenden Ultraschallwellen 16, 17, 18 wird die Walze 4 und auf dieser die Emulsion 14 in Schwingungen versetzt, deren Frequenz im für Ultraschall typischen Bereich liegt. Dadurch wird erreicht, dass das Feuchtmittel und die Druckfarbe, welche im Bereich der Emulsionsstörung 15 durch den Stoß lokal stark demulgiert sind, schnell wieder emulgieren. Die Beseitigung der Emulsionsstörung 16 erfolgt noch bevor diese die Kontaktlinie 10 erreicht und auf die Druckform 3 übertragen werden kann. Durch eine entsprechende Einstellung der Ultraschallquelle 8 ist die Intensität der Ultraschallwellen 16, 17, 18 variierbar. In Abhängigkeit von der Einstellung der Intensität können verschiedene Emulgiergrade der Emulsion 14 auf der Walze 4 eingestellt werden. Neben der bereits beschriebenen und das Emulgieren verbessernden Wirkung der Ultraschallwellen 17, 18, 19 unmittelbar innerhalb jenes Umfangsbereiches 20 der Walze 4, in welchem die Ultraschallwellen 17, 18, 19 auftreffen, haben letztere auch eine Fernwirkung innerhalb des Walzenspaltes bzw. der Kontaktlinie 9 zwischen den Walzen 4 und 5. Die durch die Ultraschallwellen 16, 17, 18 in Mikroschwingungen relativ zur Walze 5 versetzte Walze 4 bewirkt regelmäßige Mikrostörungen der Emulsion 14. Die gewollt erzeugten und während des Druckens permanent hervorgerufenen "Mikrostörungen" überlagern die ungewollte und viel stärkere Emulsionsstörung 16, so dass diese im Druckbild kaum noch auffällt, falls es durch den Einsatz der Ultraschallquelle 8 nicht gelingen sollte, die Emulsionsstörung 16 vor deren Übertragung auf die Druckform 3 vollständig zu beseitigen.
