Definitions

  • the invention relates to a rotary screen printing device of the type mentioned in the preamble of the main claim.
  • DE-OS 2.259.225 discloses a method for dyeing or printing webs, preferably of pile goods, on stencil printing machines, in particular rotary stencil printing machines.
  • a device is used in which an ink tray is arranged in the interior of the circular template, the opening of which provides the respective lower section of the inside of the circular template with paint.
  • the walls of the ink tray can be provided with lip seals (DE-OS 22 50 092) or with a roller doctor blade.
  • the arrangement of doctor blades for wiping and leveling ink on the inside of circular stencils on screen printing machines is well known .
  • a rotary screen printing machine is also known, in which the doctor blade is pivotally mounted such that the doctor blade can be brought into any other desired angular position on the inner circumference of the screen template except in the known vertically downward position.
  • This adjustability of the doctor blade is provided in order to prevent the ink from running through the perforations of the circular stencil before the doctor blade ends and thus to prevent the web of material or at least the printing blanket or the impression roller from becoming dirty.
  • the paint tray according to AT-PS 349.418, which can be rotated about the longitudinal central axis of the circular template, serves the same purpose.
  • the rotary screen printing machine according to US Pat. No. 3,398,680, which defines the generic term of the device according to the invention, provides a vertical guidance of the material web between two circular sieves located at the same height, the color accumulating in a sump in each circular sieve. Excess paint from the sump can be drawn off through a suction pipe - one squeegee inside each circular stencil is provided in its horizontal center plane.
  • the object of the invention is to be able to change the color without removing the round stencil, thereby avoiding the damage to the sensitive round stencil that occurs.
  • the color change should, however, be possible in a short time and without great effort, which is particularly important in the case of small batches.
  • ink fluid losses should be reduced compared to known methods and devices when changing colors, ie the amount of ink fluid to be removed from the stencil should be reduced and be recovered.
  • an undesired passage of the color liquid through the stencil should be avoided. All of this should be done using technically simple means.
  • the advantage of the device according to the invention is that the inside of the sensitive circular stencils can be quickly cleaned by sucking off the paint that accumulates between the squeegee and the tube, without having to be removed during the color change. Sucking off also saves on paint, which would otherwise generally have to be washed off the round stencil.
  • horizontal or approximately horizontal arrangement of the squeegee and arrangement of the color addition in the lowest section of the circular stencil when the stencil is stationary, inadvertent penetration of the stencil with color is avoided in any case, even if the deepest section of the Round stencil temporarily collects paint, which is then vacuumed off.
  • the middle section 16 of this feed pipe lies at the lowest point of the round template 1, preferably directly on the inside of the round template.
  • the pipe 15 is radially adjustable with its section 16 in the direction of the double arrow 17 in the circular template 1, so that the position of the section 16 of the feed pipe 15 can be adapted to the circular template.
  • the doctor blade 22 is adjustably arranged on a bar 23.
  • the section 16 of the ink supply pipe 15 has in its lower section holes 24 distributed over the length of the pipe, which are directed in the direction of rotation - arrow K in FIG. 4 - of the round template 1 (cf. bore center line 25) and behind in the direction of rotation of the template the vertical center line M of the pipe section 16 are located.
  • the tube 15 can be rotated about its axis A.
  • the feed pipe 15 is connected to a paint feed pump as well as to a suction pump or to a combined unit, so that the pipe 15 is optionally available in a known color Way can be supplied, but excess paint can be sucked through the holes 24.
  • the ink initially retained by the doctor blade 19 or 22 runs down the stencil section 1a and accumulates in the direction of rotation in front of the pipe section 16 of the pipe 15 with its bores 24.
  • the onset of suction ensures that the ink flowing into the holes 24 is sucked off, so that on the one hand this results in a recovery of the paint to the feed pipe 15, and on the other hand the section 1a of the circular stencil is largely freed of paint and penetration of the paint to the material web is excluded.
  • the section 16 of the ink supply and suction pipe 15 can be pivoted about the longitudinal central axis L (FIG. 1) of the circular template.
  • a collecting trough 27 into the washing liquid which is introduced into the inside of the stencil via the line 16, with a rest of color which was not sucked off through the pipe 15, arrives and can be drawn off via a nozzle 28 with a hose 29.
  • the tub 27, into which excess ink can drip even during the printing process, is height-adjustable in the direction of the arrows 30 and carries seals 31 resting against the template at its edge. Without deforming the template 1, a slight negative pressure can be present in the tub 27 are generated to draw off washing liquid from the interior of the template.
  • the paint feed and suction pipe is subdivided into a feed pipe and a suction pipe separate therefrom. While the former is at a distance from the inner wall of the template e.g. can be arranged in the II. circular quadrant (FIG. 4), the suction pipe is designed and arranged like the pipe 15 with the section 16. It can be rotated and swiveled like this. The washing liquid can be brought into the interior of the template via one of the two pipes.
  • the doctor blade 22 has an angle ⁇ relative to the vertical of less than 45 0, preferably from 10 - 30 °. Furthermore, the doctor blade is designed in a known manner as a spring element and bears on the inside of the template 1 with a greater or lesser prestress. Due to this small angle of attack of the doctor blade, the color is guided into the gusset between doctor blade 22 and stencil 1 and, due to the acute-angled wedge surface of the doctor knife, is pressed through the stencil without the need for gravity.
  • the vertical arrangement of the stencils 1 and the impressioners 2 makes it possible to bring an apron or curtain 42 between the impressioners 2 or between the web 3 and the stencils 1 during the color change and washing process of the stencils 1, which can be raised and lowered.
  • the tube 15 takes over the function of the ink supply, the suction of excess paint and the supply of rinsing and washing water. The same applies when using a separate ink supply and a paint suction tube.
  • the washing liquid can also be passed through a separate pipe into the interior, which preferably has spray nozzles directed towards the template.
  • the doctor bar can also be designed as a tube which supplies washing liquid or can carry such a tube.
  • a doctor bar 23 is again provided with a doctor knife 22 located approximately in the horizontal, whose angle of attack against the inner wall of the template rotating in the direction of arrow I is less than 45 °.
  • a suction pipe 31 is arranged, which leaves a small space 32 between itself and the inner wall of the template.
  • the tube 31 has an indentation 33 opposite the angle ⁇ between the doctor blade 22 and the stencil, in the middle of which a longitudinal slot or row of holes 34 is provided arranged in an indentation 36 of the tube.
  • the trough corresponding to the trough 27 of FIG. 3 can also be provided below the template 1.
  • washing liquid enables the washing liquid to be sucked through the suction pipe 31 through the suction pipe 31 after the ink 37 that has accumulated in front of the doctor blade has been sucked up to supply, for which this tube can be connected to a paint suction unit and to a line supplying washing liquid. Either the washing liquid can be sucked off through the template 1 at the level of the tub or the pipe 15a serves as a suction element for the washing liquid.
