Definitions

  • the invention relates to a water tank for a dampening unit of an offset rotary printing press according to the preamble of patent claim 1.
  • US Pat. No. 3,045,592 shows a water tank with a weir for regulating a moisture level.
  • the weir is equipped with recesses that allow the water tank to drain.
  • DE-B-1 611 322 shows a water tank with a height-adjustable drainage nozzle. A device for collecting the dampening solution flowing out of the drain pipe is not provided.
  • FR-A-1 518 171 shows a water tank which is divided into two chambers by means of a weir. One chamber has an outlet, the other an inlet. The drain and inlet of the water tank are connected to a common pump container by means of hoses.
  • ductor rollers promote paper abrasion in the water tank. This paper debris deposits as sludge at the bottom of the water tank. To remove this sludge, the water tank must be removed for cleaning. For this purpose, inlet and outlet hoses have to be dismantled disadvantageously, which leads to longer machine downtimes.
  • the invention has for its object to provide a water tank for a dampening unit of an offset rotary printing press, which can be removed from the machine without loosening hoses or tubes.
  • the advantages that can be achieved with the invention are, in particular, that short process, production or machine-related downtimes can be used to clean the water tank. Since the water tank is equipped with weirs designed according to the invention, the surface tension of the dampening liquid has no influence on the uniform flow of the dampening liquid in the water tank. This leads to an even overflow of the weirs and thus to an even drain of the dampening liquid from the water tank.
  • a water box 1 of an offset rotary printing press consists of a front wall 2, a left side wall 3, a rear wall 4, a right side wall 6 and a floor 7.
  • the walls 2, 3, 4 and 6 all have the same height k with respect to the floor 7.
  • the walls 2, 3 and 6 are perpendicular to the floor 7.
  • An opening angle ⁇ between the rear wall 4 and the floor 7 is z. B. 135 °.
  • the water tank 1 has a circular hole 9 in the bottom 7.
  • a drain pipe 11, which is flush with an inner surface 12 of the bottom 7, is welded into the hole 9.
  • the drainage pipe 11 consists of an approximately 15 mm long piece of pipe 20 x 1. Parallel to the front wall 2, at a distance a from the front wall 2, a vertical outlet weir 13 extending over an entire length of the water tank 1 is attached.
  • An upper part 14 of the outlet weir 13 is towards the front wall 2 at an angle a of e.g. Angled 45 °.
  • the outlet weir 13 has semicircular recesses 16 which are at a distance b from one another.
  • the outlet weir 13 has a plurality of drain holes 17.
  • Parallel to the outlet weir 13, an inlet weir 18 is attached at a distance d (approx. 8 cm) from the outlet weir 13 and extends over the entire length of the water tank 1.
  • the inlet weir 18 is perpendicular to the floor 7, with an upper part 19 of the inlet weir 18 towards the rear wall 4 at an angle a of e.g.
  • the inlet weir 18 has a plurality of semicircular recesses 21 which are at a distance e (approximately 20 cm) from one another. At a short distance f from the bottom 7 of the water tank 1, the inlet weir 18 has a plurality of small drain holes 22.
  • a height g of the inlet weir 18 is greater than a height h of the outlet weir 13 and less than the height k of the walls 2, 3, 4 and 6.
  • the walls 3 and 6 are extended downwards beyond the base 7 and each have a hook-shaped receptacle 23, 24 at the front edge on their lower edge.
  • the water tank 1 is suspended on bolts 28, 29 fastened in side frames 26 and 27 of the machine.
  • the water tank 1 is supported via its downwardly elongated walls 3 and 6, each on a bolt 31 and 32 fastened in the side frames 26 and 27, respectively.
  • a tubular inlet 33 for a dampening fluid is attached to the left side frame 26.
  • An opening 34 of the inlet 33 is located above the water tank 1 between the inlet weir 18 and the rear wall 4.
  • a funnel 39 is arranged coaxially to the outlet nozzle 11 and at a distance m from it, just below the outlet nozzle 11. The funnel 39 is inserted into a drain pipe 36 fixed to the frame.
  • the drain pipe 36 is attached to a cross member 37 fixed to the part.
  • the funnel 39 is designed such that its smallest outlet cross section is larger than a largest outlet cross section of the outlet connector 11.
  • a dampening liquid flows from the inlet 33 between the inlet weir 18 and the rear wall 4 into the water tank 1. Since a cross section of the inlet 33 is larger than a sum of the cross sections te of all drain holes 22 in the inlet weir 18, the dampening liquid builds up in front of it until it has reached the upper edge.
  • the dampening fluid flows through recesses 21 of the inlet weir 18 into a space between the inlet weir 18 and the outlet weir 13 and builds up in front of it up to its upper edge.
  • the dampening liquid flowing out via the recesses 16 of the outlet weir 13 runs out of the water tank 1 through the outlet connection 11 and is fed to the outlet pipe 36 via the funnel 39.
  • the dampening liquid flows to a commercially available dampening liquid circulation system and from there via feed pipes and inlet 33 back into the water tank 1 .
  • the empty water tank 1 can be conveniently removed from the dampening unit of a printing press without the aid of tools.
