Definitions

  • the invention relates to a short inking unit according to the preamble of claim 1.
  • a short inking unit of this type is known from US-A 4,490,855.
  • This known arrangement is used for processing flexographic printing inks or glue, in any case for processing thin, water-like substances.
  • the two doctor blades are inclined towards one another in a roof shape, which results in a symmetrical doctor blade arrangement.
  • the closing squeegee that is the squeegee that the cylinder circumference passes first, is accordingly positive in relation to the cylinder circumference of the anilox roller.
  • a positive squeegee is subject however hydrodynamic interferences depending on the cylinder speed. It is therefore disadvantageous that the pre-doctoring caused by the closing doctor is speed-dependent and is subject to hydrodynamic interferences.
  • the residues present on the anilox roller consist of residual ink, dirt particles in the form of paper dust and the like, and in particular dampening solution.
  • An inadequate decrease in the dampening solution results in a bad affinity of the anilox roller for new ink.
  • the overflow opening is placed in such a way that the ink chamber is only partially filled with ink. The ink chamber remains empty above this filling.
  • US-A-2 015 193 shows a chambered doctor blade arrangement with a doctor blade holder, on which two doctor blades arranged parallel to one another in the direction of rotation are accommodated, in contrast to which the cylinder circumference passes first is negative towards the top of the cylinder circumference of the assigned cylinder, which has a smooth cylinder surface.
  • the two doctor blades do not limit a filled ink chamber, but only flank an ink chamber formed by solid partition walls.
  • the roller to be inked is not an anilox roller, which must be completely scraped off the webs, so that the negative doctor blade position is practically irrelevant here.
  • the further doctor blade, on which the cylinder circumference last passes is positioned positively with respect to the cylinder circumference.
  • the closing doctor blade i.e. the doctor blade on which the cylinder circumference passes first, also performs a reliable, speed-independent and consequently free doctoring of the anilox roller when processing tough offset inks due to its negative position. This ensures that no ink or water film remains on the webs of the screen of the anilox roller, which can improve the affinity of the anilox roller for new color and thus the filling of the cells and has a particularly advantageous effect on the homogenization of the ink flow.
  • the ink can be present in the ink chamber with a slight overpressure, combined with the good affinity of the anilox roller for new ink due to the negative pre-squeegee ensures that a reliable filling of the cells with color is achieved, which is advantageously imposed on the range of colors and the dosage.
  • an uncontrolled pump can advantageously be used as a result of the maintenance of at least one overflow opening for supplying the ink to the ink chamber, which has an advantageous effect on keeping the required effort low.
  • the doctor blade at the rear in the direction of rotation of the anilox roller can enclose a smaller obtuse angle with the periphery of the anilox roller than the doctor blade at the front in the direction of rotation.
  • This measure results in an adjustment of the respective squeegee angle to the special needs of the closing and working squeegees.
  • a further advantageous measure can consist in the fact that the doctor blade, which is at the back in the direction of rotation, has at least one overflow opening spaced from the doctor blade edge and is underpinned by a discharge channel provided outside the ink chamber and preferably arranged at a gradient.
  • the overflow openings provided in the area of the closing doctor blade do not prevent the generation of overpressure in the ink chamber, since the anilox roller conveys the ink away from these overflow openings. At the same time, however, this ensures that fresh paint emerges from the paint chamber via the overflow openings. This hits in the area of the drainage channel inevitably on the paint doctored off by the closing squeegee, so that it is reliably mixed with fresh paint and local dirt accumulations are avoided.
  • the short inking unit on which FIG. 1 is based consists of a rubberized applicator roller 2 cooperating with a plate cylinder 1 covered with hard offset printing plates and having the same diameter as the plate cylinder and an anilox roller 3 which cooperates with the application roller 2 and has a smaller diameter.
  • the application roller 2 interacts simultaneously with a dampening unit designated as a whole by 4.
  • the circumference of the anilox roller 3, which is made of steel, is provided with cups 5 indicated in FIG. 1 and the webs 6 delimiting them. The cups 5 are filled with paint, the webs 6 are scraped off, so that there is an exact dosage of the paint corresponding to the capacity of the cups 5.
  • the ink supply to the anilox roller 3 and the doctoring take place by means of a chamber doctor blade arrangement designated as a whole in FIG.
  • a plurality of chamber doctor blade arrangements arranged next to one another for example two chamber doctor blade arrangements 7 each comprising half a roller length, can be provided over the length of the anilox roller 3.
  • the use of a plurality of chamber doctor blade arrangements arranged side by side facilitates handling and enables the ink supply of the anilox roller 3 to be shut down zone by zone.
  • the chambered doctor blade arrangement 7 comprises, as can best be seen from FIG. 2, a bar-shaped doctor holder 9 which can be received on fixed supports 8 and on which two doctor blades 11 and 12 held by jaws 10 and offset in the direction of rotation of the associated anilox roller 3 are accommodated.
  • the doctor blades 11 and 12 can be clamped using the jaws 10.
  • the jaws 10 together with the doctor blade holder 9 are intended to delimit a holding slot into which the doctor blade blades 11, 12 can be inserted loosely, that is to say without clamping.
  • the holding slot mentioned has a clear width which is about 3 / 100mm to 4 / 100mm above the thickness of the doctor blade assigned in each case.
  • This unclamped arrangement of the doctor blades 11 and 12 ensures that the doctor blades can expand in their longitudinal direction, provided that heating occurs during operation. As a result of this degree of freedom of the doctor blades, it is achieved that the doctor blades remain straight in the event of heating.
  • the doctor pressure can accordingly be comparatively small, which has a favorable effect on the avoidance of wear.
  • the loose doctor blade arrangement simplifies the doctor blade change.
  • the doctor blade 11 which is at the rear in the direction of rotation of the anilox roller 3, functions as a pre-doctor blade, which wipes off residues such as residual ink, water, dust particles etc. adhering to the peripheral section of the anilox roller 3 coming back from the contact area with the applicator roller 2.
  • the residues wiped off by the doctor blade 11 are collected by a drainage channel 14 underneath it, arranged with a slope.
  • the doctor blade at the front in the direction of rotation of the anilox roller 3 acts as the main doctor blade, which, after the inking of the periphery of the anilox roller 3 has been inked, scrapes off the webs 6.
  • the two doctor blades 11, 12 offset from one another form the rear and front boundaries of an ink chamber 13 in the direction of rotation of the anilox roller 3 radial boundaries are formed by the doctor holder 9 or the circumference of the anilox roller 3.
  • the ink chamber 3 is closed at the end by sealing jaws described in more detail below.
  • both doctor blades 11, 12 rest against the circumference of the anilox roller 3 with a negative angle of attack, the direction of rotation indicated by an arrow cannot be reversed here.
  • the negative inclination of the two doctor blades 11, 12 ensures that hydrodynamic interference does not occur in the area of the main doctor blade as well as in the area of the pre-doctor blade, even at high speeds of rotation of the anilox roller 3.
  • the front doctor blade 12 in the direction of rotation can be set somewhat steeper than the rear doctor blade 11, which has given good results in tests.
  • the ink chamber 13 is supplied with ink.
  • the ink chamber 13 can be connected to an ink pump 16 in a pressure-tight manner by means of a supply line 15 which is only indicated schematically.
  • the doctor blade holder 9 can be provided with an inflow bore opening into the ink chamber 13, via which the supply line 15 is connected directly to the ink chamber 13.
  • the doctor blade holder 9 is provided with a distributor chamber 17 which is formed by an axial bore and which extends over an outward direction Threaded bore 18, to which the supply line 15 can be connected in a pressure-tight manner, can be supplied with paint and from which a plurality of inflow bores 19 opening out into the ink chamber 13 and distributed over the length of the doctor holder 9 extend. This ensures a particularly uniform filling of the ink chamber 13 over its entire length.
  • the ink pump 16 circulates the ink, the ink in the ink chamber 13 being present with a slight overpressure, which ensures good filling of the cells 5.
  • excess ink is discharged through one or more overflow openings. As indicated in FIG. 2, these overflow openings can be designed as bore-shaped recesses 24 of the rear doctor blade 12, which are spaced from the doctor edge. The excess ink emerging via the recesses 24 is derived from the discharge channel 14 which underlies the doctor blade 11.
  • the squeegee holder 9 can also be provided with one or more overflow bores of the type indicated at 25 leading past the distribution chamber 17 and the connection bore 18, to which a pressure-free return line 26 can be connected.
  • the overflow bores 25 are arranged near the rear corner of the ink chamber 13 in the direction of rotation of the anilox roller 3.
  • the anilox roller 3 can be acted upon with ink before it runs onto the doctor blade 11 acting as a pre-doctor blade, which is then doctored off again by the doctor blade 11.
  • the excess paint emerging from the ink chamber 13 can be used.
  • a sheet 40 arranged upstream of the doctor blade 11 can be provided which, together with the doctor blade 11, delimits an ink chamber 41 which is arranged upstream of the ink chamber 13 and in which the ink chamber 13 exits the ink chamber 13 via the recesses 24 of the doctor blade 11 Excess ink is accumulated so far that the anilox roller 3 is inked over its entire length. The excess ink emerges through the gap between sheet metal 40 and anilox roller 3 and drips into the channel 14.
  • the chamber 41 could also be acted upon via slots which pass under the holder of the doctor blade 11.
  • the end faces of the ink chamber 13 can be closed by sealing jaws 27 resting on the circumference of the anilox roller 3.
  • These are plate-shaped elements with a concave edge contour corresponding to the circumference of the anilox roller 3.
  • the sealing jaws 27 are each received in a bearing block 28 fastened to the doctor holder 9, which is provided with parallel guide grooves 29 for receiving the side edges of the sealing jaws 27.
  • the guide grooves 29 are on the end face, ie on that of the anilox roller 3 facing side and open on the opposite side, so that the plate-shaped sealing jaws 27 can be easily inserted from below in the illustrated embodiment, which facilitates assembly.
  • the bearing blocks 28 are each provided with a reciprocating piston 32 which is accommodated in an approximately centrally arranged guide tube 30 and is gripped by a prestressed spring 31 and which engages under the associated sealing jaw 27 or, as in the exemplary embodiment shown, with an engaging under or into an associated recess in the relevant one Sealing jaw 27 engaging driver 33, here in the form of a radial pin led out of the guide tube 31 through an elongated hole.
  • the sealing jaws 27 can be pressed with their area emerging from the guide grooves 29 onto the doctor blades 11 and 12 on the end face.
  • a respective associated sealing jaw 27 is provided in the region of the abutment 34 which engages behind the doctor blade 12 in the direction of rotation of the anilox roller 3 and is accommodated in an adjustable manner across an associated holding arm 35 of the bearing block 28 concerned.
  • the abutment 34 is simply designed as a tab which is fastened to a guide pin 36 which slidably engages in an associated bore of the holding arm 35 and can be locked by means of a clamping screw 37.
  • the sealing jaws 27 are provided in the area of their corner close to the circumference in the direction of rotation of the anilox roller 3 with a bevel 38, indicated in FIG. 3 and shown enlarged in FIG. 5, which runs inward at an acute angle from the outer edge. This practically results in a deflecting edge which removes the ink stripes which form in the area of the sealing jaw 27 on the anilox roller 3 and leads inwards into the effective area of the doctor blades.
