Description

Die Erfindung betrifft eine Vorrichtung zur Geräuschminderung an Druckmaschinen gemäss Oberbegriff des Anspruchs 1 (DE-A 2 243 575).The invention relates to a device for noise reduction on printing presses according to the preamble of claim 1 (DE-A 2 243 575).

Bei den Maschinen der druck- und papierverarbeitenden Industrie sind auf dem Gebiet der Lärmminderung durch Primärmassnahmen sprich durch konstruktive Massnahmen einige Verbesserungen erzielt worden. Hierbei sind zu nennen, Verwendung von Kunststoffen statt Stahl, Zahnräder mit geschliffenen Zahnflanken und einer Schrägverzahnung sowie feinere Fertigungstoleranzen der Einzelteile der Druckmaschine.With the machines of the printing and paper processing industry, some improvements have been achieved in the field of noise reduction through primary measures, i.e. through constructive measures. These include the use of plastics instead of steel, gears with ground tooth flanks and helical teeth, and finer manufacturing tolerances for the individual parts of the printing press.

Auf dem Gebiet des Sekundärschutzes hat sich beim Rollenoffset eine Vollkapselung der ganzen Maschine herauskristallisiert. Eine solche Vollkapselung lässt sich bei Maschinen für den Bogenoffset wegen der wesentlich höheren Wartungs- und Beobachtungsgänge des Bedienungspersonals nicht durchführen.In the field of secondary protection, full encapsulation of the entire machine has emerged in web offset. Such a full encapsulation cannot be carried out on machines for sheetfed offset because of the significantly higher maintenance and observation cycles of the operating personnel.

Bei den Bogenoffsetmaschinen sind aus diesem Grunde lediglich einzelne Schallschutzbleche bisher zur Anwendung gekommen. Damit ist eine Lärmquelle möglicherweise abgeschirmt worden. Diese Massnahmen kosten jedoch Geld. Erhebungen zur Lärmminderung an Rollenoffsetmaschinen haben ergeben, dass der Preis z. B. einer mittelformatigen Maschine um ca. 3-4% erhöht wird. In der Praxis bedeutet dies, dass bei der Neubestellung einer Rotationsmaschine mit der Zielsetzung einer Lärmpegelherabsetzung von 20 dB (A) die tatsächlichen zusätzlichen Kosten bei 0,1-0,15% pro Lärmpegelherabsetzung um jeweils 1 dB (A) liegen, diese Zahlen sind nicht ohne weiteres auf die Bogenoffsetmaschinen übertragbar, zeigen aber die Richtung der Kostenentwicklung auf.For this reason, only individual soundproofing sheets have so far been used in sheetfed offset presses. This may have shielded a source of noise. However, these measures cost money. Surveys on noise reduction on web offset presses have shown that the price B. a medium format machine is increased by about 3-4%. In practice, this means that when a new rotary machine is ordered with the objective of reducing the noise level by 20 dB (A), the actual additional costs are 0.1-0.15% per noise level reduction of 1 dB (A), these are the figures not readily transferable to sheetfed offset presses, but show the direction of cost development.

Ausgehend von dieser Problemstellung liegt der Erfindung die Aufgabe zugrunde, bei gleicher Bedienungsfreundlichkeit der Bogendruckmaschine eine optimale Senkung des von der Bogendruckmaschine erzeugten Geräuschpegels mit einfachen und kostengünstigen Mitteln zu erreichen.Based on this problem, the object of the invention is to achieve an optimal reduction in the noise level generated by the sheet-fed press with simple and inexpensive means, while maintaining the same ease of use of the sheet-fed press.

Die Lösung der gestellten Aufgabe bei einer Vorrichtung der eingangs genannten Art wird durch die Merkmale des kennzeichnenden Teils des Anspruchs 1 erreicht.The solution of the problem in a device of the type mentioned is achieved by the features of the characterizing part of claim 1.

Der Antrieb der Druckmaschine ist gekapselt und mit Ventilatoren belüftet. Die Geräuschemission des Antriebs, welcher unterhalb des Fusstrittes auf der Antriebsseite der Druckmaschine angeordnet ist, ist z. B. durch eine Vollkapselung des Fusstrittes eingedämmt worden. Die Vollkapselung weist zwei Entlüftungsrohre auf, so dass die Wärmeabfuhr, die durch die Antriebe unterhalb des Fusstrittes entsteht, erfolgt.The drive of the printing press is encapsulated and ventilated with fans. The noise emission of the drive, which is arranged below the foot step on the drive side of the printing press, is, for. B. has been contained by a fully encapsulated foot. The full encapsulation has two ventilation pipes so that the heat that is generated by the drives below the footstep is removed.

Die Kettenförderbahn und die Bogenfördereinrichtungen zwischen den einzelnen Druckeinheiten bzw. zum Ausleger ist abgekapselt und durch natürlichen Zug belüftet. Die entstehenden Geräusche durch die Bogenlaufbahn werden durch diese Abkapselung direkt am Ort ihrer Entstehung an ihrer weiteren Verbreitung innerhalb der Druckmaschine gehindert. Die Abkapselung der Kettenförderbahn ist in einer Art Schalldämpfer ausgeführt, der auf beiden Seiten offen ist, wobei die Ausführung der Schallisolation in Form von gelochten Schallschutzblechen ausgeführt ist. Dadurch, dass die Abkapselung beidseitig offen ist, wird ein natürlicher Luftzug innerhalb des abgedämpften Raumes erreicht. Ähnlich wie bei der Kettenförderbahn ist die gesamte Bogenfördereinrichtung gekapselt.The chain conveyor and the sheet conveyors between the individual printing units or to the delivery arm are encapsulated and ventilated by natural draft. This encapsulation prevents the noises generated by the sheet path from spreading further within the printing press directly at the point at which they are generated. The encapsulation of the chain conveyor is carried out in a kind of silencer, which is open on both sides, the sound insulation being in the form of perforated soundproofing plates. Due to the fact that the encapsulation is open on both sides, a natural air draft is achieved within the sealed room. Similar to the chain conveyor, the entire sheet conveyor is encapsulated.

Der Anleger, Ausleger und die Räume zwischen der Druckmaschine und Anleger bzw. Ausleger sind gekapselt, wobei eine an sich bekannte Beschichtung an den Blechschutzen mit schallschluckendem Material unter Beibehaltung der vorhandenen Entlüftungsöffnungen und Klappen und der Bedienbarkeit der Druckmaschine befestigt sind und resonanzfähige Blechschutze mit Antidröhnmaterial beschichtet sind. Durch diese gesamten Einzelmassnahmen der Abkapselung an der Druckmaschine ist eine optimale Pegelsenkung auf der Querschnittsmessfläche von ca. 3 bis 4 dB (A) zu erreichen. Hierbei ist der Ausgangsgeräuschpegel natürlich unterschiedlich bei jedem einzelnen Maschinentyp anzusetzen. In einer Versuchsreihe betrug der Messflächenschallpegel vor der Abkapselung der Druckmaschine ca. 86 dB (A) und nach der Abkapselung wurden lediglich 82 bis 83 dB(A) nach DIN 45635 gemessen. Diese Werte sind Querschnitte einer Vielzahl von örtlichen Pegelmessungen in und um den Bereich der Druckmaschine.The feeder, delivery arm and the spaces between the printing press and feeder or delivery arm are encapsulated, whereby a known coating is attached to the sheet metal protectors with sound-absorbing material while maintaining the existing ventilation openings and flaps and the operability of the printing press, and resonant sheet metal protectors are coated with anti-drumming material are. Through these entire individual measures of the encapsulation on the printing press, an optimal level reduction on the cross-sectional measuring area of approx. 3 to 4 dB (A) can be achieved. The output noise level is of course different for each individual machine type. In a series of tests, the measuring surface sound level before encapsulation of the printing press was approx. 86 dB (A) and after encapsulation only 82 to 83 dB (A) were measured according to DIN 45635. These values are cross sections of a variety of local level measurements in and around the press area.

Der Anleger ist durch schallschutztechnische Massnahmen ringsherum abgekapselt. Bekanntermassen ist der Anleger durch seine pneumatischen Einrichtungen einer der grössten Schallverursacher an der gesamten Maschine. Die völlige Abkapselung des Anlegers wird durch mehrere unterschiedliche Abdämmeinrichtungen erreicht. An den Seiten sind hauptsächlich Plastikschutzhauben vorgesehen, die zur einfachen Begehbarkeit des Anlegers als ganze Tür ausgeführt sein kann. Eine andere Version der seitlichen Abkapselung des Anlegers sieht einzelne Bahnen des Plastiksichtschutzes vor, derart, dass die Bahnen überlappt nebeneinander hängen. Der Drucker kann somit durch leichte Handbewegungen die einzelnen Plastikbahnen auseinanderhalten, um bei bestimmten Bedienungsvorgängen leicht an die einzelnen Hebel innerhalb des Anlegers heranzukommen. Der Ausleger ist an den grossen Blechschutzen an seinen beiden äusseren Seiten und der Oberseite mit Antidröhnmaterial ausgelegt. Das Antidröhnblech verhindert, dass die Blechschutze durch Schwingungen aus der Maschine selbst zur Lärmquelle angeregt werden, so dass sie dann selber scheppern. Damit sind einmal die Abschirmung von Schallwellen aus dem Inneren des Auslegers erreicht und zusätzlich wird das Anregen neuer äusserer Schallquellen, hier z. B. die äusseren Blechschutze, unterbunden.The investor is encapsulated by soundproofing measures all around. As is well known, the feeder is one of the largest sources of noise on the entire machine thanks to its pneumatic equipment. The complete encapsulation of the feeder is achieved by several different damming devices. Mainly plastic protective hoods are provided on the sides, which can be designed as a whole door for easy access of the feeder. Another version of the lateral encapsulation of the feeder provides individual webs of the plastic privacy screen in such a way that the webs hang overlapping one another. The printer can thus separate the individual plastic webs with slight hand movements in order to easily access the individual levers within the feeder during certain operations. The boom is lined with anti-boom material on the large sheet metal guards on its two outer sides and the top. The anti-drumming sheet prevents the sheet metal guards from being excited by the vibrations from the machine itself to the noise source, so that they clatter themselves. So once the shielding of sound waves from the inside of the boom is achieved and in addition the excitation of new external sound sources, here z. B. the outer sheet protectors prevented.

Lärmdämmende Seitenwände sind zwischen den einzelnen Druckeinheiten mit oder ohne bau-Noise-reducing side walls are between the individual printing units with or without

akustische Massnahmen befestigt. Damit sind auch die Zwischenräume die an der Druckmaschine als Schallquellen anzusehen sind, abgedeckt. Die Seitenwände sind in Form von abnehmbaren Schwingtüren befestigt, so dass auch hier die Bedienbarkeit der Druckmaschine für das Personal erhalten bleibt. Zwischen den einzelnen Druckmaschineneinheiten sind z. B. an den begehbaren Fusstritten in Höhe der Kettenförderbahn besonders günstig die vorhandenen Fussklappen schallisoliert, so dass die Kettenförderbahn die oben genannt durchgehend schallisoliert ist, und durch einfaches Öffnen der Klappe die Bedienbarkeit an der Kettenförderbahn erhalten bleibt.acoustic measures attached. This also covers the gaps that are to be regarded as sound sources on the printing press. The side walls are attached in the form of removable swinging doors, so that the operability of the printing press remains unchanged for the personnel. Between the individual printing press units, for. B. at the accessible footsteps at the level of the chain conveyor, the existing foot flaps are particularly soundproof, so that the chain conveyor is soundproofed throughout, and the operability on the chain conveyor is maintained by simply opening the flap.

In einer besonders vorteilhaften Ausführung ist auf dem Boden unterhalb der Druckmaschine eine durchgehende Schaumstoffmatte mit bauakustischen Massnahmen angeordnet. Die Schaumstoffmatte verhindert die Schallreflexion von der Druckmaschine über den Fussboden und damit die Schallausbreitung in den Druckerraum.In a particularly advantageous embodiment, a continuous foam mat with acoustic measures is arranged on the floor below the printing press. The foam mat prevents sound reflection from the press over the floor and thus the sound propagation into the printer room.

Eine spezielle Ausführung sieht vor, dass das schallschluckende Material durchgehende Löcher aufweist, und dass das Material offenporig ist und zwischen einem oder zwei identisch gelochten Blechen angeordnet ist. Hierbei sind die unterschiedlichsten Variationen möglich.A special embodiment provides that the sound-absorbing material has through holes, and that the material is open-pore and is arranged between one or two identically perforated sheets. A wide variety of variations are possible.

Die Löcher in dem schallschluckenden Material können hierbei die unterschiedlichsten Formen aufweisen.The holes in the sound-absorbing material can have a wide variety of shapes.

Die Öffnungen der gelochten Bleche besitzen vorzugsweise eine rechteckige Form, da die Form am kostengünstigsten und einfachsten in der Herstellung ist.The openings of the perforated sheets preferably have a rectangular shape, since the shape is the least expensive and simplest to manufacture.

Der Lochanteil der Öffnungen in den Blechen beträgt ca. 30% des schallschluckenden Materials, da hierbei das Optimum der Schalldämpfung bei den Dämmaterialien liegt.The percentage of holes in the openings in the metal sheets is approx. 30% of the sound-absorbing material, since the optimum soundproofing lies with the insulating materials.

In Bereichen mit Sichtmöglichkeiten auf das Innere der Druckmaschine sind Plastiksichthauben oder Plastiksichtklappen, die bei Bedienungsvorgängen weggeklappt werden können, befestigt. Es zeigt:

In der Fig. 1 ist eine Druckmaschine 1 mit einem Anleger 2 und Ausleger 3 in der Seitenansicht dargestellt. Der Anleger 2 ist mit schallisolierendem Material 6 an seiner Oberseite ausgelegt. An den Maschineneinheiten und an dem Ausleger 3 sind Blechschutze 7 und Wände 9 mit Antidröhnmaterial 8 beklebt. An der Oberseite des Anlegers 2, zwischen den Maschineneinheiten und vor den Druckzylindern sind Klappen 10 die ebenfalls schallisoliert sind, vorgesehen. Diese Klappen 10 sowie Schwenktüren 12, 12.1 ermöglichen dem Drucker die normale Bedienbarkeit der Druckmaschine 1. Am Anleger 2 ist eine solche Schwenktür 12 dargestellt, die eine leichte Begehbarkeit des Anlegers 2 bzw. Bedienbarkeit ermöglicht. Zwischen dem Anleger 2 und der nächstliegenden Druckeinheit ist auch im Bereich der Bogenlaufbahn die Schwenktür 12.1 angeordnet, die die Schallemission aus diesem Bereich verringert. Eine Kettenförderbahn 13 weist über ihre gesamte Länge unterschiedlich angeordnete Schallschutzmassnahmen in Form eines Schalldämpfers 14 auf. Der Schalldämpfer 14 ist an beiden Seiten offen und hat somit eine Naturzugentlüftung. Zusätzlich sind an der Oberseite der Kettenförderbahn 13 die Schallschutzmassnahmen in gelochter Form ausgeführt, so dass auch ein Luftzug durch die einzelnen Schallschutzmassnahmen ermöglicht wird. Unterhalb der Druckmaschine 1 ist eine Schaumstoffmatte 15 über die gesamte Länge der Druckmaschine 1 auf dem Fussboden verlegt. Die Schaumstoffmatte 15 verhindert eine Reflexion der entstandenen Schallwellen vom Fussboden unterhalb der Druckmaschine 1. Am Ausleger 3 ist ausser den Seitenwänden und der Deckfläche auch eine Hauptwand mit schallisolierendem Material 6.1 ausgelegt. Gerade an den Materialien 6, 6.1 haben sich Öffnungen 16 zur Schallisolierung besonders gut bewährt. Der Schall kann durch die Öffnungen 16 der Bleche in die unterschiedlichsten schallisolierenden Materialien 6, 6.1 eindringen und in Wärme umgesetzt werden.1 shows a side view of a printing press 1 with a feeder 2 and delivery 3. The feeder 2 is designed with sound-insulating material 6 on its top. Sheet metal guards 7 and walls 9 are covered with anti-noise material 8 on the machine units and on the boom 3. On the top of the feeder 2, between the machine units and in front of the pressure cylinders, flaps 10, which are also soundproof, are provided. These flaps 10 and pivoting doors 12, 12.1 enable the printer to operate the printing machine 1 normally. Such a pivoting door 12 is shown on the feeder 2, which enables the feeder 2 to be easily walked on or operated. Between the feeder 2 and the closest printing unit, the swing door 12.1 is also arranged in the area of the sheet path, which reduces the noise emission from this area. A chain conveyor track 13 has soundproofing measures in the form of a silencer 14 which are arranged differently over its entire length. The muffler 14 is open on both sides and thus has a natural draft ventilation. In addition, the soundproofing measures are carried out in perforated form on the top of the chain conveyor track 13, so that a draft is also made possible by the individual soundproofing measures. Below the printing machine 1, a foam mat 15 is laid on the floor over the entire length of the printing machine 1. The foam mat 15 prevents reflection of the sound waves generated from the floor below the printing press 1. In addition to the side walls and the top surface, a main wall with sound-insulating material 6.1 is also designed on the bracket 3. Especially on materials 6, 6.1, openings 16 for sound insulation have proven particularly effective. The sound can penetrate through the openings 16 of the metal sheets into a wide variety of sound-insulating materials 6, 6.1 and be converted into heat.

Der Anleger 2 weist an seinen seitlichen Aussenflächen Plastiksichtschutzhauben 18 auf. Für den Drucker besonders günstig sind weitere Plastiksichtschutzhauben 18.1 vorgesehen. Die an den einzelnen Druckmaschineneinheiten dort angeordnet sind, wo er Sicht auf die einzelnen Zylinder der Druckmaschine 1 haben muss. Die Plastiksichtschutzhauben 18.1 können durch eine einfache Schwenkbewegung aufgeklappt werden, so dass der Drucker auch an die einzelnen Zylinder innerhalb der Druckmaschine gut herankommen kann.The feeder 2 has plastic privacy hoods 18 on its lateral outer surfaces. Additional plastic privacy hoods 18.1 are provided particularly cheaply for the printer. Which are arranged on the individual printing press units where it must have a view of the individual cylinders of the printing press 1. The plastic privacy hoods 18.1 can be opened by a simple swivel movement, so that the printer can also easily get to the individual cylinders within the printing press.

Die Fig. 2 zeigt einen seitlichen Teilbereich der Druckmaschine 1 mit Antrieben 1.1. Die Antriebe 1.1 liegen unter einem Fusstritt 4. Der Fusstritt 4 ist an seinen äusseren Seitenbereichen mit schallisolierendem Material 6 völlig abgekapselt. Um einen Wärmestau unterhalb des Fusstrittes 4 im Bereich der Antriebe 1.1 zu vermeiden, sind Ventilatoren 5 vorgesehen, die den abgekapselten Bereich unter dem Fusstritt 4 entlüften. Die Geräusche der Ventilatoren 5 werden durch Schalldämpfer 11, die in den Abzugsrohren angeordnet sind, optimal gemindert. Auch der gekapselte Fusstritt 4 weist an den wesentlichen Bereichen zur Bedienbarkeit Klappen 10 und Schwenktüren 12 auf. An den Seitenbereichen der Druckmaschine 1 sind die Blechschutze 7 ebenfalls mit Antidröhnmaterial 8 ausgekleidet.Fig. 2 shows a lateral portion of the printing press 1 with drives 1.1. The drives 1.1 are under a foot step 4. The foot step 4 is completely encapsulated on its outer side areas with sound-insulating material 6. In order to avoid heat build-up below the foot step 4 in the area of the drives 1.1, fans 5 are provided which vent the encapsulated area under the foot step 4. The noises of the fans 5 are optimally reduced by mufflers 11 which are arranged in the exhaust pipes. The encapsulated foot step 4 also points to the essential areas for operability flaps 10 and swing doors 12. The sheet metal guards 7 are also lined with anti-noise material 8 on the side areas of the printing press 1.

Die Fig. 3 zeigt ein spezielles Ausführungsbeispiel eines schallisolierten Materiales 6.1, das zwischen zwei gelochten Blechen 17 angeordnet ist. Damit kann der Schall durch die Bleche 17 wie oben genannt in das Material 6.1 eindringen. Bei speziellen Anwendungsfällen kann zur Entlüftung das Material 6.1 ebenfalls durchgehende Löcher 19 aufweisen. Damit wird ein natürlicher Luftzug des abgedichteten Raumes ermöglicht, und gleichzeitig erreicht, dass der Schall auch in den Löchern 19 im Material 6.1 in Wärme umgesetzt wird. Als optimales Durchgangsloch durch das Material 6.1 hat sich hierbei ein kegelförmiges durchgehendes Loch 19 herausgestellt, bei der die grössere Öffnung des Loches 19 auf der Seite, auf der der Schall entsteht, angeordnet ist.Fig. 3 shows a special embodiment of a soundproof material 6.1, which is arranged between two perforated sheets 17. The sound can thus penetrate through the metal sheets 17 into the material 6.1 as mentioned above. In special applications, material 6.1 can also have through holes 19 for ventilation. This enables a natural draft of air in the sealed space, and at the same time ensures that the sound is also converted into heat in the holes 19 in the material 6.1. A conical through hole 19 has been found to be the optimal through hole through the material 6.1, in which the larger opening of the hole 19 is arranged on the side on which the sound is generated.

In der Fig. 4 ist ein weiteres Beispiel des schallisolierenden Materials 6 gezeigt, das in einem Blechschutz 7 eingefasst ist. Besonders gute schallisolierende Werkstoffe sind hierbei Glaswolle oder Schaumstoffmatten mit bauakustischen Massnahmen. Die Blechschutze 7 sind zusätzlich schwingungsfrei gehaltert.4 shows a further example of the sound-insulating material 6, which is enclosed in a sheet metal protection 7. Glass wool or foam mats with acoustic measures are particularly good soundproofing materials. The sheet metal guards 7 are additionally held free of vibrations.

In der Fig. 5 ist ein besonders kostengünstiger Schallschutz in Form des Antidröhnmaterials 8 dargestellt, das auf den Blechschutz 7 aufgeklebt wird. Hierbei sind zwei dünne Bleche mit einer doppelseitig klebenden Folie miteinander verbunden. Die Blechschutze 7 sind auf diese einfache Weise durch Aufbringen des Antidröhnmaterials 8 besonders gut versteift und es wird vermieden, dass die Blechschutze 7 selbst zum Schwingen angeregt werden können.5 shows a particularly inexpensive sound insulation in the form of the anti-drumming material 8, which is glued onto the sheet metal protection 7. Here, two thin sheets are connected to each other with a double-sided adhesive film. The sheet metal guards 7 are stiffened particularly well in this simple manner by applying the anti-drumming material 8 and it is avoided that the sheet metal guards 7 themselves can be excited to vibrate.

In der Fig.6 ist ein Blech 17 in der Draufsicht gezeigt. Das Blech 17 weist in dieser speziellen Ausführung rechteckige Öffnungen 16 auf, die technisch besonders einfach durch Stanzen herzustellen sind. Die besonders schalldämmend optimierte Verteilung der Öffnungen 16 führt zu einer optimalen Schallisolierung des Bleches 17 bei möglichst wenigen Öffnungen 16, da sich herausgestellt hat, dass auch ein weiteres Lochen des Bleches 17 zu keiner Steigerung der Schallverminderung führt.A plate 17 is shown in plan view in FIG. In this special embodiment, the sheet 17 has rectangular openings 16, which are technically particularly easy to produce by stamping. The particularly sound-insulating, optimized distribution of the openings 16 leads to optimal sound insulation of the sheet 17 with as few openings 16 as possible, since it has been found that a further punching of the sheet 17 does not lead to an increase in the sound reduction.
