Definitions

  • the invention relates to a dosing device with a container with a sieve arranged on the underside for the passage of flock in the form of rod-shaped bulk material and a brush roller arranged within the container over its entire width, consisting essentially of a rotatably drivable in the container at both ends Via a shaft mounted in each of the container end walls and a plurality of brush strips arranged evenly distributed in the circumferential direction and carrying substantially radially directed bristles, which are held by several brush strip carriers arranged in a rotationally fixed manner for supporting the brush strips on the shaft, and one in the sieve in the container oppositely arranged and formed by guide walls with upwardly open areas for the bulk material.
  • Dosing devices of the type described above are known to the applicant from its own production.
  • the rod-shaped bulk material for example flock
  • the brush roller arranged in the container rotates.
  • the chambers formed by the brush strips with the bristles arranged on them on the brush roller are filled with bulk material as they pass the filling opening, which they later place on the sieve arranged opposite the inlet opening and sweep through the sieve with the bristles of the brush strips .
  • This must be done with great uniformity so that the coating density of the object to be coated with the bulk material has the desired uniformity.
  • One factor influencing this is the weight pressure of the bulk material on the sieve of the container.
  • the invention is therefore based on the object of proposing a metering device with which the bulk weight of the bulk material which is deposited on the sieve can be kept uniform.
  • a wiper is provided on the inlet side of the brush strips from the inlet opening into the container with a scraper lying parallel to the shaft for wiping off excess bulk material.
  • This scraper ensures that the filling state of the individual chamber formed by the brush strips carrying the bristles is always uniform and its size is dependent on the position of the scraper edge.
  • the presence of the scraper makes it possible to always add large quantities of bulk material, since the excess bulk material is always stripped off by the scraper, so that a uniform filling level is nevertheless achieved. At the same time, this prevents underfilling.
  • the stripper is arranged with at least one component perpendicular to the sieve in a variable position.
  • the fill level and the fill weight can be adapted to the specific properties of the bulk material.
  • At least the guide wall, on which the scraper is arranged is arranged tangentially to the circular cross section of the brush roller and approximately at an angle of 45 ° in the container. In this way, a particularly advantageous position of the scraper and an even more uniform filling of all chambers is achieved.
  • the drawing shows a view into a metering device 1 with the end wall removed.
  • the dosing device 1 consists essentially of a container 2 with the container side walls 6, which has a sieve 3 on its underside 4. Opposed to the sieve 3 are angled guide walls 14 and 15 which on the one hand come to rest on the side walls 6 and on the other hand form an inlet opening 7 and which run approximately at an angle of 45 ° tangentially to the circular cross section of the brush roller.
  • the bulk material to be dosed is continuously filled into the inlet opening 7 in the direction of fall 18.
  • a brush roller consisting essentially of one. on the end walls of the container 2 rotatably mounted shaft 8, on which rotatably connected to the shaft 8 brush holder 11 are arranged, on which in the circumferential direction around the shaft 8 evenly distributed brush strips 10 with substantially radially directed bristles 9 arranged parallel to the shaft 8 and are attached.
  • the brush roller 5 rotates during operation in the direction of arrow 12, so that the bulk material filled in through the inlet opening 7 is carried along by the bristles 9 and the brush strips 10 and placed on the sieve 3 of the container and by the bristles 9 which continue to run the sieve is passed through.
  • a scraper 16 is fastened in parallel position to the shaft 8 on the inlet side 13 of the guide wall 14.
  • the scraper edge of the scraper 16 which is also parallel to the shaft 8, simply scrapes off excess bulk material, so that the chambers formed by the brush strips 10 and the bristles 9 arranged thereon then pass through the scraper 16 and its scraper edge 17 in the direction of rotation always have the same level. Since it is now possible to ensure constant overfilling due to the effect of the scraper 16, the risk of underfilling is also eliminated.
  • the brush strips 10 can be removed from the brush strip carriers 11 of the brush roller 5 and turned or exchanged for other brush strips, for example with different bristles 9 or a different length of the bristles 9.
  • the metering device 1 can be set up for different bulk goods or different bulk goods quality, or worn bristle strips can be exchanged very simply.
  • the scraper 16 can be arranged movably on the guide wall 14 so that the position of the scraper edge 17 can be changed.
  • the entire dosing device 1 described is part of an overall system for coating any surfaces, For example, for coating carpets, wallpapers or other surfaces, with rod-shaped bulk material, preferably with so-called flock, in which the rod-shaped bulk material is aligned after being passed through the sieve 3 of the metering device 1 in an electrostatic field and processed further in this aligned state.
  • the use of the scraper 16 according to the invention considerably improves the metering accuracy of the metering device 1 and simplifies the monitoring effort of the overall system.
  • the devices for filling the dosing device 1 with bulk material can be made simpler because it is now not necessary to ensure that the exact same amount of bulk material is filled in as the sieve 3 leaves below.
  • the use of the scraper 16 according to the invention is therefore associated with considerable advantages.
