Definitions

  • the invention relates to a device for applying a roll peelable double-sided adhesive tape on a printing cylinder.
  • Flexographic printing is a rotary high-pressure process for, for example Imprints on packaging, forms. Foils or the like, in which preferably printing plates made of photopolymers or rubber onto the printing cylinders be glued.
  • To make it easy to attach the clichés it is known to apply a double-sided adhesive tape on the printing cylinder, on the again the cliché is stuck. Because of the available today Adhesive tape widths require several adhesive tapes to be side by side the printing cylinder are glued.
  • a ring is placed on a cylinder of a transport device like roller table attached with double-sided tape, the width of the ring corresponds.
  • an auxiliary rail receiving the pressure plate is provided, which on the Longitudinal axis of the printing cylinder can be aligned.
  • the present invention is based on the problem of a device at the outset to provide the type mentioned, which ensures that a flawless Gluing the printing cylinder with a double-sided adhesive tape is possible without this overlaps or, in the case of adhesive tapes to be arranged next to one another, these to one another are spaced. In addition, air bubbles or wrinkles should be excluded.
  • the problem is essentially solved thereby.
  • the device includes a bracket. in the axially parallel to the impression cylinder the role of Double-sided tape is stored that the bracket on the double-sided tape has in the direction of the pressure cylinder acting pressure element and that of the Hold a cutting edge in the direction with an axially parallel cutting element going out.
  • the contact pressure element is, in particular, caused by gravity or through targeted application of force e.g. Cylinder, weights slidable in the holder stored and trained as a role.
  • the teaching according to the invention ensures that several double-sided rolls of adhesive tape Be arranged abut on a common shaft, with the Peeling off the double-sided tape from each roll ensures that this in the edge area be applied butt to butt on the printing cylinder without forms a gap or overlaps; because in that the double-sided Adhesive tape rolls on an axis parallel to the longitudinal axis, i.e. shaft of the impression cylinder aligned shaft are aligned, an aligned alignment is possible. Further it is ensured that the double-sided adhesive tape fits snugly, that is also not overlapping can be cut to length because the cutting element used is also axially parallel is aligned with the impression cylinder.
  • web by web can be applied to the cylinder with adhesive tape, where e.g. an adhesive tape roll can be moved along a shaft and then positioned is.
  • the pressing element ensures that the double-sided adhesive tape is always undergoes the necessary pre-tensioning in order to be glued to the printing cylinder without wrinkles to become.
  • the pressing element and roller can be accommodated in a slot-shaped receptacle run between which and the printing cylinder the tape is guided, so that this experiences a bias in the direction of the printing cylinder.
  • a panning in the direction of the cylinder and pressing using e.g. Control cylinder is also possible.
  • the holder has receptacles, in which Recordings the shaft of the printing cylinder is supported or the recordings on the Shaft of the printing cylinder can be supported.
  • the printing cylinder is already in the printing press or sticking devices (plate mounting devices) and then the holder with its corresponding receptacle against the pressure cylinder shaft for example, lifting hydraulically.
  • the printing cylinder can be used its shaft can be inserted in a corresponding holder then apply the tape.
  • the recordings themselves should be able to start from the side walls of the bracket are preferably formed by prism-shaped recesses.
  • each side cheek has one first receiving slot for the roll of double-sided adhesive tape or one of these receiving shaft and a second receiving slot for that as a pressure roller trained pressure element.
  • the second slot runs in the direction of Shaft of the impression cylinder. so that as a result the pressure roller is always the endeavor shows to slide within the second slot in the direction of the printing cylinder, so that the double-sided adhesive tape experiences the required pretension.
  • the pressure element can be adjusted by means of an adjustment cylinder to bear against the pressure cylinder to be brought.
  • the device Has work surface, along which the adhesive tape can be guided and on which the printing cylinder rotatably rests and that on the shaft area facing away from the work surface Lever element acts.
  • the printing cylinder is thus clearly fixed in position, to be able to turn the impression cylinder. This will automatically make the tape applied to the surface of the impression cylinder. Then it is only necessary Cut the tape to the required extent.
  • From the work surface itself can also be a holder for the double-sided Adhesive tape or the shaft receiving this run out.
  • the corresponding recordings can be designed as legs or side cheeks and are preferred adjustable to each other in order to be adapted to the width of the printing cylinder.
  • the shaft of the double-sided adhesive tape can be stretched to the to pretension double-sided adhesive tape when unrolling.
  • both the pressure cylinder and the double-sided tape roll or rolls or their shaft each in one receptacle like mounting prism are stored in the cheeks of a holder, the Double adhesive tape also experiences a bias in the direction of the printing cylinder.
  • a device 18 which comprises a holder 20 which for Example is hydraulically raised to that in the pressure and assembly device installed printing cylinder 12 or its surface 10 with the double-sided adhesive tape 14 to coat.
  • the holder extends along the end faces 22 'of the pressure cylinder 12 and adjustable cheeks 22 on its length.
  • Cheeks 22 are moved along a ball bearing guide 24.
  • a leg 26 extends from a prism-like receptacle 28 for the impression cylinder 12 or the shaft 30 thereof. This is a clear placement of the Bracket 20 to the pressure cylinder 12 ensured.
  • Axial parallel to the prismatic receptacle 28 and thus to the shaft 30 of the printing cylinder 12 runs a receptacle 32 in which a shaft 34 is mounted on which one or a plurality of rolls of adhesive tape 16 are arranged butt to butt.
  • the recording 32 goes thereby from a first slot 36. to ensure safe storage when pulling the To enable double-sided adhesive tape 14.
  • the shaft 30 of the Printing cylinder 12 axially parallel to the shaft 34 of the adhesive tape rolls 16, so that as a result multiple rolls of tape and sections of one and the same roll of tapes butt and thus the adhesive tape peeled off from them merging into one another can be glued side by side on the surface 10 of the printing cylinder 12.
  • the double-sided adhesive tape 14 can be securely attached to the surface 10 of the printing cylinder 12 is ensured without wrinkling the double-sided adhesive tape 14 between a pressure roller 38 and the pressure cylinder 12, see above that the adhesive tape 14 experiences a bias in the direction of the printing cylinder 12.
  • the Pressure roller 38 can be moved in a second slot 40 due to gravity be arranged so that an automatic adjustment to the circumference of the double-tape adhesive roll 16th or the pressure cylinder 12 takes place without readjustment being necessary, alternatively can the pressure roller 38 by means of the actuating cylinder (Fig. 4) in the direction of the pressure cylinder be adjusted.
  • a cutting device 42 with an axially parallel extends from the cheeks 22 to the shaft 28 of the printing cylinder 12 and thus the shaft 34 of the double-sided tape roll 16 extending cutting element 44 to the double-sided adhesive tape 14 in to be able to cut to the required extent.
  • the cutting element 44 like knives extends vertically from a leg 46 of the cutting device 42, in the latter
  • a groove-shaped receptacle 48 is provided on the upper side, in which the pressure roller 38 can be inserted. This is necessary if a new double-sided adhesive tape 14 is on the Surface 10 of the printing cylinder 12 is to be glued.
  • the pressure cylinder 12 which is in a Pressure and assembly device is located by means of a lever element 52 with a prismatic Recording 54 for the shaft 30 aligned axially parallel.
  • a prismatic Recording 54 for the shaft 30 aligned axially parallel.
