Definitions
- the present invention relates to a device for wiping a machine for intaglio printing comprising a wiping cylinder and an installation for the continuous cleaning of said cylinder, this installation comprising a container for receiving the cleaning liquid.
- a device for wiping a machine for intaglio printing comprising a wiping cylinder and an installation for the continuous cleaning of said cylinder, this installation comprising a container for receiving the cleaning liquid.
- which acts permanently on the wiping cylinder and cleaning elements in contact with the periphery of the wiping cylinder comprising, in the direction of rotation of this cylinder, a first cleaning element, which removes most of the ink from the wiping cylinder, followed, at defined distances, by several other elements constituted by brushes and / or scrapers, at least one row of nozzles parallel to the axis of the wiping cylinder, the nozzles being arranged for ejecting the cleaning liquid in the region of the region of contact of said first cleaning element with the wiping cylinder.
- doctor blade is quite effective, since it alone removes practically 90% of the ink from the surface of the wiping cylinder, it has been found in use that, due to friction important between the doctor blade and the cylinder, friction which is reinforced by the angle inclination acute scraping with respect to the periphery of the wiping cylinder, the surface of the cylinder undergoes very great wear forces which risk damaging it, all the more so since this surface is made of synthetic material, in particular PVC. In addition, it was found that said doctor blade very quickly becomes sharp, which increases the wear of the wiping cylinder and forces the user to replace this doctor blade about every 24 hours.
- the present invention proposes to overcome the drawbacks inherent in a steel doctor blade by sparing the surface of the wiping cylinder while reducing the cost of maintenance.
- the installation according to the invention is characterized in that the first cleaning element is made of textile material in the form of a strip which is mounted folded back on itself on and along a rigid support, so to overflow from it.
- This textile material is preferably made of porous synthetic fibers.
- a first cleaning element is thus obtained which is as effective as a rigid scraper but which, thanks to its flexibility, does not risk damaging the surface of the wiping cylinder, which therefore increases the life of the latter. Another advantage is that the wear being less than with a steel scraper, the life of the cleaning element itself is longer, of the order of eight days, which is clearly more economical for the user.
- FIG. 1 represents a schematic view of the device for cleaning the wiping cylinder.
- Figure 2 is an enlarged partial view of the contact area of the first cleaning element with the wiping cylinder.
- the wiping device comprises a wiping cylinder 1, rotating in the direction of arrow F, intended to be in permanent contact with the plate cylinder not shown, the peripheral direction of rotation of this wiping cylinder 1 being opposite to that of the plate cylinder.
- This wiping cylinder 1 is partially arranged inside a container 2 in which the cleaning installation is mounted.
- the surface of the wiping cylinder 1 is made of synthetic material, in particular PVC, which ensures good wiping of the plate cylinder.
- the cleaning installation comprises, in a manner known per se, several cleaning elements constituted, in the example considered, by a doctor blade 3 forming an obtuse angle with the periphery of the cylinder 1 located following this doctor blade direction of rotation of said cylinder, and by brushes 4 arranged at a distance from one another around the periphery of cylinder 1.
- a first cleaning element 5 consisting of a textile material of porous synthetic fibers, with a thickness of between 5 and 20 mm, preferably 10 mm, sold for example by the company 3M under the name "Scotch-Brite" or "hand pad".
- This textile material is in the form of a strip whose dimension in the axial direction of the cylinder corresponds to the length of the latter so that the entire surface is covered, and which is mounted, folded back on itself (FIG. 2), on and along a support 6 so as to protrude therefrom.
- the inclination of the support 6 is adjustable to adjust the contact pressure between the strip of textile material and the surface of the cylinder 1, this support 6 having the same configuration as the doctor blade which, in the previous installations, was intended to carry the steel scraper.
- This element 5 which is fixed in any known manner to the support 6, is intended to apply tangentially over the entire length of the wiping cylinder 1 during the rotation thereof, forming an acute angle with the periphery of the cylinder located after this element in the direction of rotation of the cylinder, and to rub its surface so as to remove approximately 90% of the quantity of ink present on the surface of the wiping cylinder.
- Above the first cleaning element 5 is provided a row of spray nozzles 7 directed just before the contact zone of said element 5 with the cylinder 1.
- nozzles 8 In the support 6 is provided a second row of nozzles 8 whose mouths are directed towards inside the fold formed by the first cleaning element 5. These nozzles 7 and 8 are intended to send under pressure a cleaning liquid which, on the one hand, deterges the ink and, on the other hand, wets and rinses permanently cleaning element 5, which prevents fouling thereof during friction.
- the cleaning liquid from the nozzles 7, 8 and the nozzles associated with the brushes 4 is collected in the container 2 and flows through outlet orifices 11 so that the wiping cylinder 1 is not immersed in the soiled liquid.
- a separation wall 2 ′ in the container 2 makes it possible to separate the cleaning liquid coming from the nozzles 7, 8, which is soiled by the greatest amount of ink from the less dirty liquid coming from the nozzles associated with the brushes 4.
