Definitions

  • the invention relates to a rotary brush for cleaning a printing cylinder of a printing press with a brush element having a bristle element, wherein the bristles of the bristle element are the same length.
  • a device for cleaning a printing cylinder with a driven rotary brush whose axis of rotation is parallel to the axis of rotation of the printing cylinder and having a arranged on a drive shaft brush assembly, wherein the brush assembly comprises a plurality of axially successively arranged sleeve-shaped brush elements.
  • the rotary brush used there which is composed of a plurality of brush elements, it is easier to replace individual worn brush elements. It is also contemplated to use different brush elements on the same shaft.
  • Object of the present invention is therefore to provide a rotary brush, which provides relief in this regard.
  • a rotary brush of the type mentioned above wherein wear-resistant, harder and / or stiffer bristles are provided in one or the axial end regions of the brush element than in an axial central region of the brush element.
  • the brush element can be designed so that in a region in which an increased stress is expected, a different bristle trim is selected, so that the brush at this point does not wear so much and replacement of the brush element will be necessary later.
  • two areas are provided, whose bristle stock has different properties than the remaining area of the brush element.
  • the one or two regions with different properties of the bristle lining may be arranged at the end of the brush element. This has particular advantages in the cleaning of pressure rollers, since they usually have more pollution at their ends. Accordingly, if the rotary brush is designed so that the end portions are provided with another garnish which is more wear-resistant, the life of the brushes can thereby be prolonged.
  • the bristle facing has different properties at both ends of the brush element than in the region of the brush element lying between the ends.
  • the bristle lining has the same properties at the ends of the brush element. As a result, care must be taken when installing the brush element on its orientation. The cleaning effect is the same at both ends of the brush element.
  • an area ⁇ 20% in each case has a bristle facing with different properties.
  • the range at the end can be ⁇ 15% or ⁇ 10%.
  • the size of the area can be selected and adjusted.
  • the rotary brush has a particular hollow cylindrical body.
  • the hollow cylindrical body may be formed of steel, in particular of precision steel according to DIN 2391.
  • Such a body has a particularly thin wall in the range of 1 - 5 mm and has a high accuracy, which has a positive effect on the concentricity and the deflection.
  • Such materials are commonly known by the terms CFK and GFK.
  • the bristles of the trimming are held in a carrier which is arranged helically.
  • the carrier may be helically applied to the body.
  • the carrier may be glued to the body.
  • the bristles of the trimming are tuft-like arranged in recesses of the body.
  • the tufts can be punched, for example, in holes in the body.
  • gaps may arise that can be avoided in the helical winding of a wearer. In the latter case, there are no gaps in the stocking.
  • the trimming is one-piece tight. This is also an advantage over brush assemblies constructed of multiple brush elements. There is often a gap at the joint between two brush elements to watch.
  • the rotary brush according to the invention can have bristles with a larger diameter at least in one area of the stocking than in another area.
  • the stiffness can be adjusted via the diameter.
  • the bristle length of the bristles of the brush element can also be varied.
  • the bristles may become longer toward the center of the brush element, resulting in a bulbous shape of the trim. Seen in section, the brush element may have a convex shape.
  • the bristles can also become shorter toward the center of the brush element, so that when viewed in the (longitudinal) section, a concave shape or a double cone-like shape is created.
  • the bristles may also have the same length in a central region and then become longer towards the end of the brush element, in particular linearly, so that the ends of the brush element are conical.
  • the bristles are spliced at least in a region of the stocking. Different bristle lengths in different areas of the rotary brush are conceivable.
  • a bristle mixture of different bristles may be provided in one area.
  • smooth, ie straight bristles, and wavy bristles can be mixed to adjust the moisture absorption of the trim in this area.
  • bristles of different materials in a region of the stocking and thereby adjust the properties of the stocking.
  • the moisture absorption of the stocking can be adjusted in this area.
  • the brush element is arranged on a shaft.
  • the brush element can be driven either indirectly via a pressure cylinder to be cleaned or the shaft can be driven.
  • the brush element is arranged rotationally fixed on a drivable shaft. This means that the brush element itself can be rotated to clean a printing cylinder.
  • the brush element between two rotatably arranged on the shaft can be arranged rings or discs for non-rotatable arrangement of the brush element on the shaft. This will ensure that the brush element rotates together with the shaft.
  • a particularly reliable rotationally fixed connection results when the brush element has one or more pitch sections at least on one end face, and the associated ring or disk has corresponding pitch sections.
  • the brush elements can be formed helically at least in sections at their ends.
  • the ring or the disc are preferably adapted to the contour of the brush element, so that there is a good rotational connection.
  • at least one stop, a projection or a recess may be provided on the front side, which cooperate with corresponding corresponding contours of the disc or of the ring.
  • a device for cleaning a printing cylinder with a rotary brush according to the invention whose axis of rotation is arranged parallel to the axis of the printing cylinder to be cleaned.
  • the Fig. 1 shows a rotary brush 1 with a brush element 2, which is arranged between two end rings 3, 4.
  • the brush element 2 has a stocking 5 with bristles.
  • the stocking 5 is divided into three different areas 6, 7, 8.
  • the areas 6, 8 are provided at the end of the brush element 2.
  • the bristles in the regions 6, 8 have different properties than the bristles in the region 7.
  • the region 7 makes up about 60% of the brush element 2, while the regions 6, 8 each account for about 20%.
  • the bristles in the regions 6, 8 have a diameter in the range of 0.25-0.5 mm, while the bristles in the region 7 have a diameter in the range of 0.15-0.2 mm. Due to the different diameters, the bristles in the areas 6, 8 are stiffer.
  • the bristles in the end regions thus have a larger diameter than the bristles in the remaining region.
  • the bristles are arranged in a carrier 9, which is helically wound on a body 10.
  • the body 10 is hollow cylindrical and made in the embodiment of precision steel.
  • the body 10 can be placed on a shaft, not shown here. Characterized in that the carrier 9 is wound helically, the brush element 2 on the front side in each case a slope.
  • the end rings 3, 4 are provided, which also have a slope.
  • the end rings 3, 4 can be rotatably mounted on a shaft. The fact that they have a contour which is adapted to the slopes on the end faces of the brush element 2, this can be done via a rotationally fixed fixation on the shaft.
  • the Fig. 2 shows a similar arrangement as the Fig. 1 , with the difference that no body 10 is provided. Otherwise, the same elements are provided, which therefore also carry the same reference numerals.
