Definitions

  • the invention relates to a device for the extensive application of spreadable media, such as glue, varnish, etc., on a preferably web-shaped carrier material, in particular a printed paper web, with two working cylinders delimiting a working gap through which the carrier material can be passed, of which at least one is used as a is formed from a core with a peripheral support existing transfer cylinder, to which a supply device is assigned, which preferably contains at least one applicator roll which can be brought into contact with the assigned transfer cylinder.
  • a device for the extensive application of spreadable media such as glue, varnish, etc.
  • Glue devices of the type mentioned at the outset are known (see, for example, US Pat. No. 4,574,732). These are usually found on so-called inline production lines Use. These known arrangements consist of a stationary frame on which the working cylinders and the associated supply devices are accommodated. It is therefore practically not possible to replace the working cylinders.
  • glue a comparatively soft peripheral surface of the transfer cylinder is required.
  • comparatively thick foam clichés glued to a metal core are used, which are cut according to the desired print image.
  • lacquer a circumferential surface formed by a rubber blanket is used.
  • a stationary base frame having at least one application device and a receiving device for a cassette, on each of which an exchangeable cassette provided with two working cylinders can be fixed.
  • the measures according to the invention offer the possibility of a quick and easy cylinder change, so that the device according to the invention can be converted quickly and easily, for example from glue application to lacquer application and vice versa, the core diameter of the transfer cylinder or the transfer cylinder being adapted in each case to the special needs of the individual case can.
  • the cassette or cassettes intended for glue application can be provided with at least one transfer cylinder, the core diameter of which is smaller than the core diameter of the transfer cylinder or cylinders of a cassette intended for coating application. Relining is therefore advantageously not necessary, which is what not only has an advantageous effect on the surface hardness that can be achieved, but also on cylinder durability.
  • Another advantage of the measures according to the invention can be seen in the fact that by removing the cassettes a spacious bypass can be created for the carrier material if the device according to the invention is to be out of operation. It is therefore advantageously not necessary to create such a bypass by pivoting the working cylinders. Rather, only the removable cassette has to be removed. It is also advantageous that the cartridge-side working cylinders are easily accessible when the cartridge is removed, which facilitates cleaning, maintenance and repair.
  • the measures according to the invention also advantageously make it possible to expand existing basic equipment step by step by simply purchasing additional exchangeable cassettes or by providing the base frame with an attachment. The measures according to the invention thus advantageously ensure a high degree of versatility and thus result in excellent overall economy.
  • the working diameter of the working cylinders 1, 2 corresponds to the working diameter of the printing unit cylinders of the upstream printing press, which is intended to prevent so-called duplication.
  • the lower cylinder 1 function as a transfer cylinder and the upper cylinder 2 as a counter cylinder. This has a hard metal surface here.
  • the working cylinder 2 acting as a counter-cylinder can be provided with an ink-repellent dampening film, which will be explained in more detail below.
  • the working cylinder 1, which acts as a transfer cylinder consists of a metal core 4, onto which a circumferential support 5, which is in contrast soft, is applied.
  • the supply device 6 here consists of an application roller 7 which bears against the transfer cylinder and which interacts with an immersion roller 9 which dips into a tub 8 and a metering roller 10.
  • the application roller 7 and the dipping roller 9 cooperate here with the side doctor blades 11 which are doctoring off their end faces.
  • the storage tub 8 is loaded with glue or varnish depending on the operating mode. This can be done in a continuous process.
  • the storage trough 8 can be provided with a conditioning device for cooling or heating the respective medium.
  • FIGS. 1 and 3 two supply devices 6 arranged one above the other are provided. These are on one stationary base frame 12 added. It would be conceivable to design the base frame 12 in two parts, that is, to design it in such a way that it initially only contains the lower supply device 6 and can be expanded by an attachment which accommodates the upper supply device 6, as indicated by the parting line 13.
  • the working cylinders 1, 2 are accommodated on an exchangeable cassette 14 which can optionally be accommodated on the base frame 12.
  • the base frame 12 is provided with a corresponding receiving device, here in the form of a wall recess 15, into which the exchangeable cassette can be inserted with a corresponding projection. Bolts and / or screws can be provided for adjustment and fixation, as indicated at 16.
  • the exchangeable cassette 14, which can be detachably fixed on the base frame 12, is removable and can be replaced by another exchangeable cassette, the working cylinders of which are set up for a different operating mode. Accordingly, a plurality of interchangeable cassettes 14 of the type indicated in FIG. 2 can be assigned to a base frame 12.
  • Each exchangeable cassette 14 consists of a cassette frame 17 on which the associated working cylinders 1, 2 are accommodated.
  • the cassette frames 17 of all interchangeable cassettes 14 are the same and configured so that they fit on the associated receiving device 15 of the base frame 12.
  • the arrangement and design of the working cylinders 1, 2 of the different exchangeable cassettes 14 are different in order to be able to accomplish different operating modes.
  • the working cylinders 1, 2 of the interchangeable cassette 14 fixed to the base frame 12 in FIG. 1 are arranged such that only the lower working cylinder 1, which functions here as a transfer cylinder, comes into contact with the application roller 7 of the adjacent, lower supply device 6.
  • the lower working cylinder 1, which acts as a transfer cylinder, is designed here so that glue can be applied to the paper web 2.
  • the diameter of the core 4 is dimensioned such that soft, comparatively thick foam clichés can be accommodated on it to form the peripheral cover 5.
  • the thickness of these foam blocks is 3 to 4 mm.
  • the tub 8 of the lower supply device 6 activated here is supplied with glue in the operating mode on which FIG. 1 is based.
  • the upper supply device 6 is shut down.
  • the interchangeable cassette on which FIG. 2 is based is used to apply glue to the top of the paper web 3.
  • the working cylinder 1 which acts as a transfer cylinder, is located above the working cylinder 2, which acts as a counter-holding cylinder.
  • the upper working cylinder 1 is arranged such that it is inserted the exchangeable cassette 14 into the base frame 12 in contact with the neighboring one Application roller of the upper supply device 6 comes, which is activated in this case. Otherwise, the construction of the working cylinders 1, 2 of FIG. 2 can correspond to the arrangement according to FIG. 1.
  • the exchangeable cassette 14 fixed to the base frame 12 in FIG. 1 is simply removed and replaced by the exchangeable cassette 14 on which FIG. 2 is based.
  • the upper supply device 6 is activated and the lower supply device 6 is passivated.
  • each working cylinder 1, 2 of the exchangeable cassette 14 fixed to the base frame 12 comes to rest against the respectively adjacent applicator roller 7.
  • Both working cylinders 1, 2 function here as transfer cylinders and simultaneously as counter-cylinders assigned to the respective opposite working cylinder.
  • the working cylinders 1, 2 designed for paint application in turn consist of a core 4 with a peripheral support 5 accommodated thereon.
  • This is formed here by a rubber cover with a thickness of approximately 1.5 mm to 2 mm.
  • a rubber cover can be placed on the core 5 vulcanized or a rubber blanket.
  • the diameter of the core 4 is in this case corresponding to the smaller thickness of the circumferential cover 5 used here than the core of transfer cylinders provided for glue application. Both supply devices 6 are applied with paint here.
  • the working cylinder functioning as a counter-cylinder could in turn be provided with a chrome surface and arranged so that it does not come into contact with the adjacent applicator roller.
  • the working cylinder functioning as a transfer cylinder could have the structure on which FIG. 3 is based and be arranged such that it comes into contact with the adjacent applicator roller 7. If the entire work unit on which FIGS. 1 and 3 are based is to be stopped, the exchangeable cassette 14 is removed and the web 3 is simply passed through the then cassette-free base frame 12.
  • the device of the present type arranged between the last printing unit and dryer can be driven by the main machine drive of the printing machine, as indicated in FIG. 3.
  • at least one roller accommodated on the base frame 12 can be connected in terms of drive to a longitudinal shaft 18 of the machine main drive which extends over all units to be driven.
  • both are application rollers 7 can be driven by means of the longitudinal shaft 8.
  • drive trains 20 are provided leading to both application rollers 7, each provided with a clutch 19 for switching on and off.
  • the application rollers 7 can be provided with lateral spur gears from which the drive of the cartridge cylinders 1, 2 on the cassette side can be derived.
  • these can also be provided with lateral spur gears, the lateral spur gear of the working cylinder respectively functioning as the transfer cylinder coming into engagement with the spur gear of the assigned applicator roller 7 when the interchangeable cassette 14 in question is inserted into the base frame 12.
  • the drives 9 can be assigned individual drives with controllable motors in order to be able to set the desired speed difference.
  • the metering rollers 10 can be without a drive.
  • the working cylinders 1, 2 coming into contact with the web 3 can also be switched on or off in accordance with the printing on or off of the printing unit cylinders of the upstream printing press.
  • the working cylinders 1, 2, as can also be seen in FIG. 3, can be mounted in adjustable eccentric bushes 21, which can be actuated by means of the pressure adjusting or pressure adjusting device of the printing press.
  • a further swiveling of the working cylinders is not necessary, since the exchangeable cassette 14 can simply be removed to accomplish a spacious bypass when the device is shut down.
  • the exchangeable cassettes 14 on which FIGS. 1 and 2 are based are each provided with a moistening device 22 which is assigned to the working cylinder 2 and which can each consist of a dampening roller 23 and an immersing roller 24 which cooperates therewith and is immersed in a fountain solution pan.
  • the dampening roller 23 can be covered with a stocking made of plush, so that the associated working cylinder 2 is simultaneously wiped and cleaned during operation.
  • the dampening roller 23 can accordingly be driven at a relative speed with respect to the working cylinder 2.
  • the dampening solution Water or simply the offset dampening solution of an upstream offset printing machine can be used as the dampening solution. Since the working cylinder 2 is prepared here on the one hand with an ink-repellent dampening film and on the other hand is permanently wiped, it is ensured that the peripheral surface of the working cylinder 2 can be kept clean over long operating times. In the example on which FIG. 3 is based, in which both working cylinders 1, 2 function as transfer cylinders, the exchangeable cassette 14 is of the type outlined above without a dampening and wiping mechanism.
