Opfindelsen angår et hoveddrev for rullerotations-offsettrykmaskiner med gummi-gummitrykværker, der er anbragt i rækkearrangement og hver har to samvirkende offsetcylindre, som via cylindriske tandhjul står i direkte 5 indgreb, og som hver via cylindriske tandhjul står i drivforbindelse med den tilhørende pladecylinder, og hvor hvert gummi-gummitrykværk som hoveddrev har to cylindriske hovedtandhjul, som står i indgreb med hinanden og med de cylindriske hovedtandhjul hos nabotrykvær-10 ket, og som via lejetappe er lejret i sidestativet, samt hvor de cylindriske hovedtandhjul, som er udført med meget stor nøjagtighed, ligger i en anden hjulflugt end parret af cylindriske tandhjul mellem pladecylinder og offsetcylinder.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a main drive for roller rotation offset printing machines with rubber rubber printing presses arranged in rows and each having two cooperating offset cylinders which are directly engaged by cylindrical sprockets and each are driven by cylindrical sprockets with the associated plate cylinder and wherein each rubber-rubber thrust head unit has two cylindrical main sprockets which engage with each other and with the cylindrical main sprockets of the neighboring thrust and which are mounted in the side frame via bearing pins and wherein the cylindrical main sprockets are made of very large accuracy, lies in a different wheel flight than the pair of cylindrical gears between plate cylinder and offset cylinder.
15 Fra DE-offentliggørelsesskrift nr. 2.637.795 ken des der et hoveddrev af denne art, hvor der for hvert trykværk anvendes to cylindriske tandhjul, som står i direkte indgreb. Hvert af disse cylindriske tandhjul står i indgreb med hvert sit cylindriske drivtandhjul 20 hos de to pladecylindre, og de cylindriske drivtandhjul, som hører til de to plade-offsetcylinderpar, kan ligeledes stå i indgreb. Dette kendte hoveddrev muliggør en optimal drejningsfejlfri drivning af gummi-gummitryk-værkerne, med ringe spillerum og slid, men det er kost-25 bart på grund af det dobbelte drivarrangement for hvert trykværk, og det muliggør kun en defineret kraftstrøm uden særlig justering, når drivhjulene for de to gummicylindre ikke står i indgreb med hinanden.15 From DE Publication No. 2,637,795 there is a main drive of this kind in which two cylindrical gears which are in direct engagement are used for each printing plant. Each of these cylindrical gears interacts with each of its cylindrical drive gears 20 of the two plate cylinders, and the cylindrical drive gears belonging to the two plate offset cylinder pairs may also be engaged. This known main drive allows for optimum torque-free operation of the rubber-rubber printing plants, with little leeway and wear, but is costly due to the dual drive arrangement for each printing plant, and allows only a defined power flow without special adjustment when the drive wheels of the two rubber cylinders do not engage each other.
Med udgangspunkt i den indledningsvis omhandlede 30 konstruktion har opfindelsen til opgave at skabe et optimalt drejningsfejlfrit hoveddrev af enkel opbygning med ringe spillerum og slid, méd en vilkårlig diameter af de cylindriske hovedtandhjul og med en defineret kraftstrøm i drivhjulene.The object of the present invention is to create an optimum rotational faultless main drive of simple construction with little clearance and wear, with an arbitrary diameter of the cylindrical main sprockets and with a defined power flow in the drive wheels.
35 Til løsning af denne opgave er hoveddrevet ifølge opfindelsen ejendommeligt ved, at der kun til én af de to pladecylindre hører et cylindrisk drivtandhjul, som står i indgreb med et af de to cylindriske hovedtandhjul.35 In order to accomplish this task, the main drive according to the invention is peculiar in that only one of the two plate cylinders has a cylindrical drive sprocket which is in engagement with one of the two cylindrical main sprockets.
148820 2148820 2
Med denne drivning af gummi-gummitrykværket via kun ét cylindrisk drivtandhjul opnås der en forenklet opbygning af hoveddrevet, hvortil kommer, at diameteren af de cylindriske hovedtandhjul kan fastlægges frit, så af-5 standen mellem trykværkerne kan afpasses efter de foreliggende krav. Drivningen sker uden forspænding respektive deformation af de deltagende cylindriske tandhjul.With this operation of the rubber-rubber thrust via only one cylindrical drive gear, a simplified structure of the main drive is obtained, in addition the diameter of the cylindrical main gears can be freely determined so that the distance between the printing plants can be adjusted according to the present requirements. The drive takes place without bias or deformation of the participating cylindrical gears.
Til trods herfor opnås der til stadighed en defineret kraftstrøm inden for drevet. Med løsningen ifølge opfin-10 delsen lettes også anbringelsen af hvert trykværks to pladecylindre i skråstilling. Ved bortfald af nævnte forspænding respektive deformation kan der overføres højere ydelser for samme dimensionering af drivhjulene.Despite this, a defined power flow is constantly achieved within the drive. The solution according to the invention also facilitates the placement of two plate cylinders in an inclined position. In the event of loss of said bias or deformation, higher benefits can be transferred for the same dimensioning of the drive wheels.
Med foranstaltningerne ifølge krav 2 og 3 opnås der 15 yderligere forenklinger af drevet med cylindriske tandhjul. Det har således vist sig særlig fordelagtigt, at der til frakobling af trykværkerne kun er behov for én kobling i forhold til to koblinger med gensidig elektrisk låsning ved drivning via to pladecylinder-drivhjul.By the measures according to claims 2 and 3, 15 further simplifications of the drive with cylindrical gears are achieved. Thus, it has been found particularly advantageous that in order to disconnect the printing plants only one coupling is required in relation to two couplings with mutual electric locking when operating via two plate cylinder drive wheels.
20 Fra EP-A trykskrift nr. 0.022.381 kendes der en konstruktion af anden art og baseret på et andet princip end konstruktionen ifølge opfindelsen, idet der i stedet for et hoveddrev med cylindriske tandhjul anvendes en længdeaksel, som via koniske hjul og mellemhjul overfø-25 rer drivkræfterne til de enkelte trykværker. I modsætning til, hvad der gør sig gældende ved konstruktionen ifølge opfindelsen, optræder der ved den kendte konstruktion drejningsfejl mellem de enkelte trykværker, hvilket resulterer i dublering med deraf følgende makulaturforø-30 gelse, hvortil kommer, at der kræves flere tandindgreb, og at de anvendte koniske hjul altid udviser fremstil-lingsunøjagtigheder.20 from EP-A printing no. 0.022.381, a construction of a different kind is known and based on a different principle than the construction according to the invention, instead of a main drive with cylindrical gears, a longitudinal shaft which is transmitted via tapered wheels and middle wheels -25 supplies the driving forces for the individual printing plants. Contrary to what is claimed in the construction according to the invention, in the known construction, rotational errors occur between the individual printing works, which results in doubling with consequent shredding, in addition to which more tooth operations are required and the tapered wheels used always exhibit manufacturing inaccuracies.
Opfindelsen forklares nærmere i det følgende ved en udførelsesform under henvisning til tegningen, hvor 35 fig. 1 viser et sidebillede af et trykværk, og fig. 2 et deltværsnit af drevet.The invention will be further explained in the following by an embodiment with reference to the drawing, in which FIG. 1 is a side view of a printing plant, and FIG. 2 is a partial cross-section of the drive.

Fig. 1 viser en rullerotations-offsettrykmaskine, der består af trykværker 1, 2 og 3. Gennem disse trykværker føres der hovedsagelig horisontalt en papirbane 4 i retning af en pil. Trykværkerne modtager papirba-5 nen 4 fra en ikke vist rullebærer. Efter trykningen kan papirbanen 4 via et tørreaggregat forarbejdes videre, f.eks. i et falseapparat. Ved den viste maskine drejer det sig om en såkaldt 'Ijummi-gummimaskine", hvor papirbanen 4 føres mellem offsetcylindre 5, 6 og 10 trykkes.FIG. 1 shows a roller rotation offset printing machine consisting of printing plants 1, 2 and 3. Through these printing plants, a paper path 4 is generally passed horizontally in the direction of an arrow. The printing plants receive the paper web 4 from a roller carrier not shown. After printing, the paper web 4 can be further processed via a drying unit, e.g. in a folding device. In the illustrated machine, this is a so-called 'Rubber Rubber Machine', where the paper web 4 is passed between offset cylinders 5, 6 and 10.
Hver af de to offsetcylindre 5, 6 samarbejder med en pladecylinder 7, 8. I den viste udførelsesform hører der til den øvre pladecylinder 7 et cylindrisk drivtandhjul 9, som står i indgreb med hoveddrevets 15 cylindriske hovedtandhjul 10. På tilsvarside måde kan der ske drivning via pladecylinderen 8.Each of the two offset cylinders 5, 6 cooperates with a plate cylinder 7, 8. In the illustrated embodiment, the upper plate cylinder 7 includes a cylindrical drive sprocket 9 which is in engagement with the cylindrical main sprocket 10 of the main drive 10. via the plate cylinder 8.
Som vist i fig. 1 findes der for hvert trykværk to i indgreb stående cylindriske hovedtandhjul 10, 11, som står i indgreb med de cylindriske hovedtandhjul, der 20 hører til nabotrykværket. I den viste udførelsesform står trykværket l's cylindriske hovedtandhjul 11 således i indgreb med trykværket 2's cylindriske hovedtandhjul 10, som igen står i indgreb med det cylindriske hovedtandhjul 11. Samme indgrebsforhold findes 25 mellem trykværkerne 2 og 3, hvor trykværket 2's cylindriske hovedtandhjul 11 ligeledes står i indgreb med trykværket 3's cylindriske hovedtandhjul 10.As shown in FIG. 1, for each printing plant there are two engaged cylindrical main sprockets 10, 11 which are in engagement with the cylindrical main sprockets belonging to the neighboring printing press. Thus, in the illustrated embodiment, the cylindrical main sprocket 11 of the printing plant 1 engages with the cylindrical main sprocket 10 of the printing plant 2, which in turn engages the cylindrical main sprocket 11. The same engagement relationship exists between the printing plants 2 and 3, where the printhead 2's cylindrical main sprocket 11 engagement with the cylindrical main gear 10 of the printing plant 3.
De cylindriske hovedtandhjul drives af en ikke vist drivmotor, som kan høre til et vilkårligt trykværk.The cylindrical main gears are driven by a drive motor (not shown) which can belong to any printing plant.
30 Ved siden af de cylindriske hovedtandhjul 10, 11 befinder der sig - i en anden hjulflugt - på pladecylinderen 7's akseltap 12 et cylindrisk drivtandhjul 13, som via et yderligere cylindrisk tandhjul 14 kobler pladecylinderen 7 sammen med gummicylinderen 5. Det 35 cylindriske drivtandhjul 14 og et yderligere cylindrisk drivtandhjul 15, som står i indgreb med hinanden, er anbragt på hver sin af to akseltappe 16, som hører til de to offsetcylindre 5, 6. Offsetcylinderen 148820 4 6's cylindriske drivtandhjul 15 står i indgreb med et cylindrisk drivtandhjul 17, som hører til pladecy-lindereri 8, og som er fastgjort på en akseltap 18, der hører til pladecylinderen 8, fig. 2.30 Next to the cylindrical main gears 10, 11 there is - in a second wheel flight - on the shaft pin 12 of the plate cylinder 7 a cylindrical drive gear 13, which via a further cylindrical gear 14 links the plate cylinder 7 with the rubber cylinder 5. The 35 cylindrical drive gear 14 a further cylindrical drive sprocket 15 which engages each other is disposed on each of two shaft pins 16 which belong to the two offset cylinders 5, 6. The offset cylinder 148820 4 6's cylindrical drive sprocket 15 engages a cylindrical drive sprocket 17 which belong to plate cylinder liner 8 and which is attached to a shaft pin 18 belonging to plate cylinder 8, fig. 2nd
5 I udførelsesformen ifølge fig. 1 optager hvert trykværks sidestativer 19 lejringer for cylindrene og valserne. Til pladecylindrene 7 og 8 hører der farve-værker 20 og fugteværker 21.5 In the embodiment of FIG. 1, the side racks of each printing plant 19 take up bearings for the cylinders and rollers. The plate cylinders 7 and 8 include color works 20 and moisture works 21.
Med henblik på tryktilkobling og -frakobling er de 10 to offsetcylindre 5 og 6 lejret svingbart i deres lej-" ringer på en sådan måde, at de kan tilkobles respektive frakobles såvel i forhold til de to pladecylindre 7 og 8 som i forhold til hinanden. Via lejringerne for pladecylindrene kan disse bringes i en skråstilling. De 15 hertil anvendte lejringer er ikke vist på tegningen. Det cylindriske drivtandhjul 9 har desuden en ikke vist omkredsregisterindstilling, ved hjælp af hvilken de to pladecylinder-, offsetcylinderpar kan drejes.For pressure connection and disconnection, the two two offset cylinders 5 and 6 are pivotally mounted in their bearings in such a way that they can be engaged and disconnected respectively in relation to the two plate cylinders 7 and 8 as well as to each other. The bearings used for this are not shown in the drawing, and the cylindrical drive sprocket 9 also has a circumferential register setting not shown, by means of which the two plate cylinder, offset cylinder pairs can be rotated.
Hoveddrevets to cylindriske hovedtandhjul 10, 11 20 er via rullelejer". 22 og lejetappe 23 lejret i side- ' . stativet 19. Diametrene af de to cylindriske hovedtandhjul 10, 11 andrager i den viste, udfør el se s form ca. 540 mm og svarer sammen hovedsagelig til afstanden mellem trykværkerne 1, 2 respektive 2, 3. Da anord-25 ’ningen af samme - betinget af konstruktionen - ikke sker i en flugt, svarer diameteren ikke nøjagtigt til afstanden mellem trykværkerne. Ved en forøgelse af diametrene kan afstanden forøges.The two cylindrical main sprockets 10, 11 20 of the main drive are mounted by roller bearings ". 22 and bearing pin 23 are mounted in the side frame 19. The diameters of the two cylindrical main sprockets 10, 11 are in the illustrated embodiment, approximately 540 mm in shape and together correspond mainly to the distance between the printing plants 1, 2 and 2, 3 respectively. Since the device 25 of the same - contingent on the construction - does not occur in an escape, the diameter does not exactly correspond to the distance between the printing plants. is increased.
Via støttebolte 24 er der til sidestativet 19 30 lejret en plade 25, som bærer en gevindflange 26. I define findes der en drejeligt lejret gevindtap 27, som via en kobling 28 aksialforskyder det cylindriske driv-tandhjul 9 i forhold til en i og for sig kendt kile-akselforbindelse og rykker det ud fra hoveddrevets cy-35 lindriske hovedtandhjul 10 (stiplet vist stilling). Ved udrykningen af det cylindriske drivtandhjul 9 .standses pladecylindrene 7, 8 og offsetcylindrene 5, 6 med de tilhørende farveværker 20 og fugteværker 21.By means of support bolts 24, a plate 25 bearing a threaded flange 26. is mounted to the side stand 19 30. In definition there is a pivotally mounted threaded pin 27 which via a coupling 28 axially displaces the cylindrical drive sprocket 9 in relation to one per se. known wedge-shaft joint and pulls it out of the main gear's cylindrical main sprocket 10 (dashed position shown). When extending the cylindrical drive sprocket 9, the plate cylinders 7, 8 and the offset cylinders 5, 6 are stopped with the associated color works 20 and dampers 21.
