Definitions

  • the present invention relates to a device and a use of the latter for cleaning scanning cylinders according to the preamble of patent claim 1.
  • British Patent No. 1,193,437 discloses rollers by means of which seeds or other foreign material which are present in a nonwoven of textile fibers are ground and thereby facilitate the removal of such impurities from the nonwoven.
  • Scraper blades are provided for cleaning the roller surfaces, which abut continuously on the lateral surfaces of the rollers.
  • British Patent No. 2,071,723 relates to a scraper arrangement in which a blade rests on the roller to be treated due to the weight of the scraper arrangement and can be lifted off the roller by rotating about an axis arranged parallel to the roller. It has a multiplicity of swivel plates, by means of which, together with an air cushion, the blade is to be adapted to the irregularities of the roller surface.
  • EP-A-0 015 121 also discloses a cleaning device for the surface of rotating, smooth rollers, in which scrapers are provided for cleaning, which are intermittently brought into contact with the outer surface of the sensing cylinder.
  • the means defined in the characterizing part of claim 1 are provided according to the present application. This gives you the advantages of proper cleaning of both the bottom of the groove and the side walls of the measuring groove and significantly less wear on both the feeler cylinder and the scraping blades. Since the latter are only used for an indefinite period, they also need to be serviced less often.
  • Fig. 1 two feeler cylinders 11, 12 of a feeler cylinder pair are shown, which are rotatable about the axes 13, 14.
  • One of the disks 15, 16 is attached to each sensing cylinder 11, 12.
  • the radius of each of the disks 15, 16 is greater than that of the cylinder 11, 12 assigned to them.
  • each cylinder 11, 12 has a flange-like circular disk 17 and 18 along its circumference, the widths of which are shown by the dotted lines.
  • the end faces 19, 20 of the cylinder 11 and the end faces 21 and 22 of the cylinder 12 lie in two mutually parallel planes 23, 24. Between the cylinders 11 and 12 there is a continuous fiber sliver.
  • the scraper 26 is used to clean the feeler cylinder 11.
  • the scraper 26 comprises a drive cylinder 27 with a piston 28 movable therein and a piston rod 29.
  • the latter carries a scraper blade 30 attached to it.
  • This has the shape of an elongated, flat plate. It is shown in FIG. 1 in the scraping position and in FIG. 2 in its position moved away from the scraping position. From Fig. 1 it can be seen that the scraping blade 30 abuts in its scraping position on the lateral surface of the cylinder 11 and on the side wall of the flange-like disk 17 located on the side of this cylinder 11.
  • a return spring 31 is also provided for the piston 28.
  • a screw-on cover 32 is attached over the cylinder 27.
  • the line 33 serves to supply a pressure medium into the interior of the drive cylinder 27.
  • support members 34, 35 are also provided. These are fastened to a holder 36, which is provided in particular for carrying the cylinder 27.
  • the feeler cylinders 11, 12, biased against each other by means not shown, rotate about their axes 13, 14 and thereby move the sliver 25 running between them.
  • One cylinder rotates about a fixed axis, while the second cylinder rotates perpendicular to its axis of rotation Direction is movable.
  • the sliver 25 is held together laterally by the flange-like disks 17, 18. The more fibers the sliver 25 has, i.e. the denser it is, the less it is compressed by the cylinders 11, 12 and the more the sensing cylinders 11, 12 are moved apart. The fewer fibers the band 25 has, the less dense it is and the closer the feeler cylinders 11, 12 move together under the effect of their pretension.
  • the thickness of the fiber sliver 25 is thus measured by means of the mutual distance between the feeler cylinders 11, 12 and a signal dependent on the thickness is formed by means not shown. This can e.g. B. to control the fiber feed to compensate for the sliver 25.
  • the means used for these processes are not shown in the drawing and have nothing to do with the present invention.
  • a scraper 26 is provided for cleaning the cylinder 11.
  • the cleaning takes place in such a way that the scraper blade 30 of the scraper 26 is moved intermittently into contact with the lateral surface of the cylinder 11 and again away from it.
  • a pressure medium is pressed periodically via the line 33 into the interior of the drive cylinder 27 and the piston 28 is thereby moved against the tension of the return spring 31.
  • the scraping blade 30 is pressed against the outer surface of the scanning cylinder 11, as a result of which it is cleaned. If the pressure is released again by the medium, the return spring 31 causes the scraper blade 30 to move away from its scraping position.
  • the piston 28 can also be moved back by pneumatic or hydraulic means.
  • the groove formed by the flange-like disks 17, 18, in which the sliver 25 passes can be formed in that on one of the two sensing cylinders, e.g. B. on the cylinder 11, on each of its end faces 19, 20 a flange-like disc is attached, but no such are provided on the cylinder 12.
  • the scraper blade must be brought into contact with the lateral surface of the cylinder with the two flange-like disks in a movement parallel to the end faces of the feeler cylinders. If the side walls of the groove are also to be cleaned, the scraper must be given a rectangular shape, so that, when immersed in the groove, the scraper cleans both the outer surface to be cleaned and the inner side walls of the groove at the same time.
  • one disk 15 is attached to the end face 20 of the feeler cylinder 11 and the other disk 16 to the end face 21 of the feeler cylinder 12 to form a groove for the fiber sliver 25.
  • the arrangement of the scraper 26 has an oblique position in which the axis of the piston rod 29 is relative the planes 23, 24 are angled at an angle a.
  • the scraper blade 30 is advantageously also given a shape angled by this angle a, as shown in FIG. 1.
  • This embodiment has the advantage that when the scraper blade 30 bears against the lateral surface of the cylinder 11, this at the same time, i.e. in a single movement, can also be brought into contact with the side wall of the flange-like disc 17, which is located on the side of the cylinder 11, and so that these two surfaces can be cleaned simultaneously.
  • the two edges 37, 38 of the scraper blade 30, which are in contact in this case, form the right angle, which is designated in FIG. 1 with the sign used for right angles.
  • the angle a which the straight line 39 forms with the planes 23, 24, can be between 5 ° and 30 °. This also applies to the angled part of the scraping blade 30.
  • the relatively high precision of the blade width is not necessary, which must be present in the embodiment in which both flange-like disks are located on the same sensing cylinder.
  • the blade 30 is pierced between the front ends of the support members 34 and 35.
  • at least one support member is designed to be elastically flexible. In the example shown in FIG. 2, this is the case with the organ 35.
  • the support member 34 is made of a solid material and thus serves in particular for support taking into account the direction of rotation of the cylinder 11 with the disk 17 indicated by an arrow.
  • Removing the impurities is not a problem because only small amounts are generated during the individual cleaning movements. If you want to prevent them from falling on any undesired spot, you can use suitable means, e.g. B. be removed by suction. But it can e.g. B. an arrangement can also be used in which the end faces of the feeler cylinders are arranged horizontally. In this case, the contaminants can fall to the floor without any disadvantage.
  • the scrapers 26 are arranged horizontally, the scraping blades 30 coming to rest in a laterally lying region of the lateral surfaces of the scanning cylinders 11, 12.
  • This arrangement also has the advantage that the pressure of the scraper 26 has practically no influence on the position of the movable of the feeler cylinders and thus on the thickness measurement of the sliver.
  • the thickness of the scraper can be, for example, 0.5 millimeter (mm).
  • the size of the space between the free ends of the support members 34, 35 is between 0.1 mm and 0.4 mm.
