Description
455 285 Enligt uppfinningen uppnås detta syfte vid en tyckmaskin av inledningsvis angivet slag genom kännetecken enligt åt- följande patentkrav 1. According to the invention, this object is achieved in a grinding machine of the type initially indicated by features according to the appended claim 1.
Uppfinningen beskrives nedan i form av två utföríngsexempel och med hänvisning till åtföljande ritningar.The invention is described below in the form of two embodiments and with reference to the accompanying drawings.
Figur 1 visar en schematisk sidovy av en valsrotations- offsettryckmaskin med två så kallade satellittryckverk.Figure 1 shows a schematic side view of a roll rotation offset printing machine with two so-called satellite printers.
Figur 2 visar en schematisk sidovy av en valsrotations- offsettryckmaskin med ett satellittryckverk för dubblerat genomlopp av en bana med halverad bredd.Figure 2 shows a schematic side view of a roll rotation offset printing machine with a satellite printing unit for double passage of a half-width web.
Figur 3 visar ett snitt genom mottryckscylindern i ett satellíttryckverk för en valsrotations-offsettryckmaskin enligt figur 2.Figure 3 shows a section through the back pressure cylinder in a satellite printing plant for a roll rotation offset printing machine according to Figure 2.
Vid den på figur 1 schematiskt visade valsrotations-offset- tryckmaskinen avrullas på känt sätt en bana 1 från en i en valsväxlare 2 lagrad förrådsrulle 3 och tillföres ett första satellittryckverk 4, där banan förses med fyrfärgs- tryck på en sida medelst fyra till en central mottrycks- cylinder 5 hörande platt-/gummicylinderpar 6. Efter detta första tryckningsförlopp torkas banan 1 i en första tork- apparat'7 och ledes därefter över en första grupp kylval- sar 8.In the roller rotation offset printing machine schematically shown in Figure 1, a web 1 is unrolled in a known manner from a supply roll 3 stored in a roller exchanger 2 and is fed to a first satellite printing unit 4, where the web is provided with four-color printing on one side by four to a central counter-pressure cylinder 5 belonging to plate / rubber cylinder pair 6. After this first printing process, the web 1 is dried in a first drying apparatus 7 and then passed over a first group of cooling rollers 8.
För att_förse baksidan med fyrfärgstryck genomlöper banan ett andra satellittryckverk 9 som likaledes består av en central mottryckscylinder 10 med fyra tillhörande platt-/ gummicylinderpar 11. Efter det andra tryckníngsförloppet torkas banan 1 åter i en andra torkapparat 12 och tillfö- res därefter en falsapparat 14 över en andra grupp kyl- valsar 13. 455 285 Dà trycklängden kan ändras under torknings- och kylförloppet i beroende av banans 1 kvalitet, kan dragnings- och inpassnings~ problem för det andra tryckningsförloppet uppträda. För att under drift kunna bemästra dessa problem är enligt uppfinningen minst en av de báda mottryckscylindrarna 5,10 anordnad att drivas med reglerbar periferihastighet oberoende av tillhörande platt-/ gummicylinderpar 6,11, exempelvis via en konventionell, ej särskilt visad finregleringsdrift. Regleringen kan utföras antingen manuellt eller automatiskt i förbindelse med kända anordningar för mätning av banans dragning och registeravkänning.In order to provide the back with four-color printing, the web passes through a second satellite printing plant 9 which likewise consists of a central counter-pressure cylinder 10 with four associated plate / rubber cylinder pairs 11. After the second printing process, the web 1 is dried again in a second drying apparatus 12 and then a folding apparatus 14 is passed over a second group of cooling rollers 13. 455 285 Since the pressure length can be changed during the drying and cooling process depending on the quality of the web 1, drawing and fitting problems for the second printing process can occur. In order to be able to overcome these problems during operation, according to the invention at least one of the two back pressure cylinders 5,10 is arranged to be operated at an adjustable peripheral speed independently of the associated plate / rubber cylinder pair 6,11, for example via a conventional, not particularly shown fine control operation. The control can be performed either manually or automatically in connection with known devices for measuring the trajectory and register sensing of the web.
Syftet enligt uppfinningen kan även uppnås genom att regleringen av periferihastigheten sker genom ändring av en cylinderdiameter.The object according to the invention can also be achieved by regulating the peripheral speed by changing a cylinder diameter.
Då det principiellt rör sig om mycket små förändringsvärden, kan ändringen åstadkommas exempelvis på känt sätt genom påverkan av styrbara termiska medel.As these are in principle very small change values, the change can be achieved, for example, in a known manner by influencing controllable thermal means.
Uppfinningstanken kan även förverkligas i en valsrotations- offsettryckmaskin enligt figur 2. Banan 15 med halverad bredd avrullas även här från en förrådsrulle 16 och tillföres den ena hälften, betraktat i axelriktningen, av ett satellittryckverk 17. Efter det första tryckningsförloppet torkas banan i tork- apparaten 18 och tillföres en vändningsanordning 20 via en första grupp kylvalsar 19. I vändningsanordningen vändes banan på känt sätt och föres i sidled parallellt med sin löpriktning en sträcka svarande minst mot banans bredd. För tryckning av banans bak- sida genomlöper den nu den andra hälften av satellittryckverket 17. Därefter torkas banan åter i torkapparaten 18 och tillföres falsapparaten 22 via en andra grupp kylvalsar 21. I denna variant av uppfinningen är mottryckscylindern 23 uppdelad i tvâ oberoende av varandra drivbara cylinderhälfter 24,25. Den första cylinder- hälften 24 är fast förbunden med cylinderaxeln 26. Den andra cylinderhälften 25 är fritt roterbart lagrad på cylinderaxeln 26 och fast förbunden med ett drivhjul 27 som står i ingrepp med en transmission 28. Åtminstone i drivkedjan för en av de båda cylinderhälfterna 24,25 är en konventionell styrbar finreglerings- drift anordnad, såscm beskrivet i anslutning till figur 1.The inventive idea can also be realized in a roll rotation offset printing machine according to figure 2. The web 15 with halved width is also unrolled here from a supply roll 16 and fed to one half, viewed in the axis direction, by a satellite printing unit 17. After the first printing process the web is dried in the dryer 18 and is fed to a turning device 20 via a first group of cooling rollers 19. In the turning device the web is turned in a known manner and is moved laterally parallel to its running direction a distance corresponding at least to the width of the web. To print the back of the web, it now passes through the other half of the satellite printing unit 17. Thereafter, the web is dried again in the dryer 18 and fed to the folding apparatus 22 via a second group of cooling rollers 21. In this variant of the invention, the back pressure cylinder 23 is divided into two independently drivable cylinder halves 24.25. The first cylinder half 24 is fixedly connected to the cylinder shaft 26. The second cylinder half 25 is freely rotatably mounted on the cylinder shaft 26 and fixedly connected to a drive wheel 27 which engages a transmission 28. At least in the drive chain of one of the two cylinder halves 24 A conventional controllable fine control operation is provided, as described in connection with Figure 1.
