Definitions

  • the present invention relates to printing presses, particularly flexographic printing presses, and more particularly to an ink system or ink fountain for such, the ink fountain being axially divided into different zones to enable different colored inks for the respective zones of an order in the zones concerned - or to use anilox roller.
  • Flexographic presses are increasingly used in the field of printing. Flexographic printing machines are usually used for printing bags, packaging materials, cardboard boxes and boxes. Recently, flexographic printing has been used outside the packaging area, mainly for books, magazines, business stationery and the like. A good review of flexo printing can be found in "Machine Printing" by Durrant, Meacock and Whitworth, copyright 1973 at Hastings House Publishers, New York, NY
  • a low-friction surface is attached to the edge which abuts the doctor blades, the sealing element bridging the space between the doctor blades and the element being fitted to the circumference of the ductor or the trough roller.
  • the doctor blades extend axially beyond the sealing elements.
  • the separating plates and the sealing elements can be mounted on units which are effectively arranged along the ink fountain and thus along the ductor or the trough roller, in positions chosen in such a way as the axial extension of the differently colored ink zones requires.
  • German patent publication DE-OS 23 20 638 to which reference is made in the aforementioned Batke patent application, describes an arrangement in which two sheet-metal elements separating the printing inks are set directly on the circumference of a duct by a spring force, in order to produce different-colored printing inks separate from each other.
  • the transverse seal of the ink container or ink sump is produced by placing the separating elements against the opposite surface of the doctor blade or doctor blade.
  • a separating strip element preferably with a low-friction surface, has a curved surface that is attached to and mates with the surface of the anilox roller.
  • the curved surface extends over part of the circumference of the roller.
  • a thin film of an aqueous liquid is introduced between the strip element and the surface of the anilox roller .
  • the strip element is made of Teflon and the liquid is water.
  • Other liquids such as water-alcohol mixtures or ink solvents can be used.
  • the liquid film is introduced into the area under the strip so that two liquid-impregnable elements are attached next to the ends of the strip element.
  • a preferred material is felt; other sponge-like materials can be used.
  • the liquid is fed to the felt elements, which act as wicks and bring the thin liquid film exactly into the area of the separating strip.
  • the strip element is backed with, for example, silicone rubber with a low durometer value. This enables the seal to set itself independently of the direction of rotation of the anilox roller.
  • Anilox rolls are commonly used with doctor blades.
  • the doctor blades are trimmed or designed so that they end at the separating elements.
  • the rubber backing enables the sealing of the squeegee corners in the printing ink chambers in addition to the ink separation elements and thus also the effective sealing of the squeegee edges, namely by the plastic deformation of the silicone rubber, i.e. by bulging over the edge when pressure is applied.
  • the ink system is arranged so that a holding structure for the separating strip elements, for the rubber backing and for the felt pads or, preferably, the entire ink fountain can be moved so that either one of the two doctor blades with the Anilox roller is in contact, depending on the direction of rotation of the anilox roller, and that the movement can also be carried out so that both doctor blades release the anilox roller, while the separating element and, preferably, the pads remain in contact with the surface of the anilox roller.
  • anilox roller can continue to rotate during the periods when there is no printing, the ink being circulated in the ink fountain and thereby preventing the ink from drying on the anilox roller, but without one of the doctor blades with the anilox roller in Touch is, whereby the wear of both the anilox roller and the doctor or doctor in question is significantly reduced.
  • the ink fountain 11, which defines a paint cavity 11a, is attached to the machine frame in a known manner. It can oscillate somewhat about an axis 11b (Fig. 2) perpendicular to the plane of Fig. 2.
  • the separating element is narrow, and it extends over part of the circumference of the anilox roller 10.
  • the separating element 2 is designed with a recess 13, into which a teflon seal 3 is inserted, which is supported on the back by a backing 5 made of silicone rubber.
  • a width of the elements 3 and 5 of approximately 15 mm is suitable.
  • the silicone rubber backing element 5 distributes the pressure of the nylon separating strip 3 evenly over the circumference of the anilox roller.
  • the compressive force in the silicone rubber can be generated by pushing against the anilox roller 10.
  • the pressure of the separating strip 3 against the anilox roller can thus be controlled.
  • a thin liquid film - typically water - is placed between the anilox roller 10 and the Teflon separating strip 3.
  • This thin water film comes from two felt pads 21, 31, which are supplied with water from a water supply network.
  • the line system for the water supply is formed by the banjo bolts 14a, 14b which are screwed into the separating element and are connected to channels 15a, 15b which are in the separating element are formed and end at the felt strips 21 and 31 respectively.
  • the shapes of the channels can be adapted to any convenient requirement, for example straight, as shown at 15a, or angled or curved, as at 15b.
  • a water trough 29 under the entire arrangement receives a possible excess of water or dripping water.
  • the screws 14a, 14b are externally threaded, and although this is not necessary, nuts 16a, 16b can be used to secure the screws against the frame 11.
  • the screws 14a, 14b are connected by means of a suitable liquid screw connection 17a, 17b to a schematically illustrated pressurized water supply line, which is used for generally common hydraulic components such as elbows, union nuts and the like. and contains the valves 18a, 18b.
  • the water can be guided selectively to the respective felt strips 21, 31.
  • the felt strips 21, 31 are held in position on the separating element 2 with the aid of the holding plates 22, 32, which comprise the felt strips 21, 31 from both sides; only one of the holding plates 22, 32 is visible in FIG. 2.
  • the doctor blades 23, 33 are selectively in contact with the surface of the anilox roller, and they run axially, ie perpendicular to the plane of the drawing in Fig.2. They are attached to the paint box.
  • the ink fountain can oscillate around the pivot pin 11b.
  • the squeegees can be axially pressed into the silicone rubber backing 5, which can be easily compressed and bulges around the squeegee, as is shown schematically at 23, 24, whereby a good seal against this is achieved.
  • the Teflon strip 3 is preferably carried out with sharp corners.
  • Teflon strip 3 and the silicone backing 5 can be inserted into the recess 13 by gluing them therein, for example with a contact adhesive.
  • the water channel through the screws 14a, 14b and the connecting channels 15a, 15b through the separating element 2 can be very narrow, for example about two to three millimeters in diameter, just enough to trickle water onto the felt cushions 21, 31 so that under the Teflon strip 3 can form a liquid film which separates the adjacent zones 10a, 10b ... and the corresponding zones on the anilox roller.
  • the arc length of the felt strips can be approximately 7 to 8 cm for a roller of approximately 28 cm in diameter.
  • the introduction of a thin film of water between the Teflon strip 3 and the surface of the anilox roller 10 has the advantage that the separating strip cannot damage the anilox roller and that a seal with an extended service life is achieved which, moreover, does not suffer from the high speed of the anilox roller 10 becomes.
  • the use of water as a film liquid has an additional advantage because it prevents the flexographic printing ink on the anilox roller from drying out in the area of the ink separation level and thus eliminates the abrasive properties of the water-based printing inks, which otherwise cause wear on the sealing material due to the application of dry printing ink to the would cause anilox roller.
  • the size and direction of the water flow to be used can be easily controlled by operating the three-way valve 18 in the water supply system to the channels 15a, 15b.
  • the amount can easily be determined by experiment; Just enough water should be used that the ink separation area does not dry out or become hard on the anilox roller.
  • the Water film with the printing ink also acts as a lubricant, and it forms a liquid film on the circumference of the anilox roller.
  • the Teflon strip 3 floats on the film, and even if the contact pressure is considerable, there is an effect similar to aquaplaning of rolling car tires on a wet road surface.
  • This liquid film effectively eliminates friction and extends the life of the seal. Just like with aquaplaning of car tires on the road, the friction is very low.
  • the ink migration across the parting line is effectively prevented because the liquid film of the liquid only allows it to remain between the anilox roller and the teflon seal and, on the other hand, prevents ink from penetrating between the teflon seal and the anilox roller.
  • the migration of printing ink with a certain property, for example a certain color, into the printing ink with another property, for example a different color, is thus effectively prevented.
  • a silicone rubber with low hardness for example a closed-cell silicone rubber with a degree of hardness (durometer) 30, arranged behind the teflon sealing strip, ensures a constant, uniform sealing pressure against the surface of the anilox roller.
  • the silicone rubber with low hardness between the wall of the separating element 2 and the teflon seal also ensures an effective seal at the corners of the doctor blades. This type of silicone rubber allows compression by about 20%, which is the reason for the slight expansion 24, 25 of the silicone rubber around the squeegee ends and squeegee corners.
  • Various materials can be used for the production of the elements 21, 31 producing the water film; Felt is particularly suitable because it enables a metered instillation or application of the water under the dividing strips 3.
  • the water comes into contact with the felt pads 21, 31 arranged above and below the teflon seal.
  • the density of the felt is such that a uniform distribution of the water is achieved.
  • the water seeps into the lower part of the felt pad due to gravity.
  • Teflon is much more expensive than silicone rubber or felt, and the use of a thin, small Teflon strip with backing with silicone rubber on the back and with felt pads on both sides reduces the amount of Teflon required. Teflon is only used in the areas of the ink fountain between the upper and lower squeegees.
  • the entire ink fountain 11 can oscillate around the pin 11b together with the separating element 2, the strip element 3, with its backing element 5 and with the squeegees 23, 33.
  • the box 11 is held on the machine frame by the bracket 40, which is coupled to a holding rod 41, which can swing around the pivot pin 11b, as is shown schematically by the arrow 42 in FIG. 2.
  • the holding rod 41 is shown broken off because the articulation pin 11b is generally further to the left in relation to FIG. 2 and it would normally not be visible in the drawing, for example because it would be hidden behind the valve 18.
  • the location in Fig. 2 was chosen only for the sake of clarity.
  • the ink fountain 11 is usually trough-shaped to form the ink cavity 11a.
  • the printing ink is continuously introduced into the ink cavity 11a through inlet openings 45 and at the outlet openings 46 drained, the ink in the ink cavity is kept in constant circulation.
  • the ink fountain 11 can be moved away with respect to the anilox roller 10, so that the two doctor blades 23, 33 lose contact with the anilox roller 10.
  • the movement is very small, a fraction of a millimeter.
  • the common axis 50 runs along the inking unit, in parallel to the color trough 11. It can swing, as indicated by arrow 51.
  • the axis 50 is coupled with the aid of an angle lever 52 to the support rod 41 or the bracket 40 of the tilting device of the separating element 2.
  • the anilox roller 10 is running clockwise, in the forward rotation, the upper cushion should be removed and the upper drip system should be switched off, e.g. the valve 18 so that the water is directed to the lower cushion 31.
  • the lower pad 31 remains in place and the lower drip or water application system is activated by the valve 18, and by this action the pad 31 applies a thin film of water to the roller 10, which enables the strip 3 to swim the film.
  • a water ring is formed on the roller 10, which separates the adjacent ink zones from one another.
  • the ink fountain 11 is pivoted about the axis 11b, see arrow 42, in order to disengage the doctor blade 23.
  • the rubber backing 5 evens out the contact pressure of the strip 3 against the roller 10.
  • the lower drip system can be switched off by changing the position of the valve 18 and the lower felt pad 31 can be removed.
  • the upper felt pad 21 remains in place and the upper drip system is turned on.
  • the unwetted pillow should be removed so that it does not dry out. Removing the felt pad is easy, you only need to pull it out, you can also loosen the fastening screws that hold the relevant clamping plate 22, 32, and then take out the respective felt strips 21, 31.
  • the roller 10 can run at speeds of more than 800 rpm, for example.
  • the roller 10 can continue to idle are left, for example at 30 rpm, the color being continuously circulated between the inlet openings 45 and the outlet openings 46 - only shown in different color zones in FIG. 1 - while the color zones remain separate from one another. After tilting the shaft 50 counterclockwise of the arrow 51, both doctor blades 23 and 33 come out of engagement with the anilox roller 10.
  • the tilt axis of the shaft 50 is preferably substantially vertically aligned with the axis of rotation of the anilox roller 10 and, for example, somewhat below the Color trough 29.
  • the normal compression of the rubber backing element 5 when printing can be about 20% of its unstressed nominal thickness, that of the felt pad about 10%.
  • a slight tilting of the ink fountain 11 allows the rubber backing 5 and the felt pads 21, 31 to relax to a certain extent, but without losing their function. In this way, the cleaning process can be eliminated during the idle periods.
  • the strip elements 3 and the pads 21, 31 remain in contact with the roller 10 and thus separate the ink zones, protecting the edges of the doctor blades 23, 33 and the surface of the anilox roller.
