Viewed in the direction of rotation of this transport roller, is the "takeover point" where the roller 33 fiber material from the feed offered beard takes over, slightly before the highest point on the transport route.

  • the separation devices 104, 106, 108 are essentially of the same design, so that the description of device 104 is representative of the other two Devices 106,108 can be viewed.
  • Each separation device thus comprises a respective one Separating element 110 and the separating element in the transport direction preceding guide element 112. Between the guide element 112 and him associated discharge element 110 is the mouth of a separation gap 1 14.
  • Each device 104, 106, 108 is preferably individual in relation to the transport roller 33 adjustable to optimize its respective excretion effect, i.e. both the Separation elements 110 as well as the guide elements 112 are opposite to that the transport roller formed transportably arranged.
  • This can be done solved that each device 104,106,108 rotatable in the side walls of the machine is mounted in such a way that the device as a "unit" around each Axis 105, 107, 109 can be rotated manually and / or by means of an actuator system, around the angular positions of the respective elements 110, 112 relative to the transport path adjust.

This material is preferred but redirected as soon as possible in a direction that is approximately parallel to the axis of rotation 170 extends, at least until it is on one side or the other of the machine reached.

  • the same approaches can be used to design a "Cleaning machine" used in a conventional blowroom line should be used, which is why the following claims do not apply to the combination are restricted with a cotton-forming device.
  • a fine cleaner When used in a fine cleaner, it will be possible to use a larger opening roller to use. While the roller 33 has a diameter in the range 250 to 300 mm, a fine cleaner should have an opening roller with a diameter larger than 350 mm e.g. 400 mm.
  • the working width can range 1 to 1.5 m, e.g. 1.2 m.
  • the preferred version 3A and 4B significantly higher demands on the precision of the working elements or assembly.
  • the opposite side Positioning of some axes of rotation can be guaranteed, namely the opening roller 33, feed roller 321 and separation devices 104, 106, 108. It must also be possible be to adjust the feed trough 322 exactly opposite the feed roller.
  • the conventional one Filling chute is a relatively simple structure with a relatively simple one Construction. The problem becomes more difficult when the conventional working width of approx. 1000 mm (e.g.) is increased to approx. 1500 mm. It is therefore clear that the conventional Construction of the shaft must be reinforced.
  • the preferred solution to the latter task is based on the strength requirements only in the area of the cleaner module, but not in the subsequent ones Manhole parts, have been increased. the solution therefore sees a cleaner module for use in cleaner according to the invention, wherein the module is a carrier for the working elements of the cleaner.
  • the carrier is characterized in that it consists of side walls and cross struts, the wall thicknesses the required ensure mutual positioning of the working elements and the cross struts to hold the side walls together.
  • the side walls can accommodate bearing parts, which rotate the working elements carry.
  • Such a module can be connected to a substructure, which the module in a suitable height relative to the card.
  • This modification preferably includes two columns, each assigned to a side wall.
  • Other elements of the shaft can be mounted on the frame, which basically consists of the Carrier of the cleaner module and its substructure.
  • each Column made of sheet metal, the sheet material of each column between the corresponding Sidewall and the cross braces is clamped to a sandwich structure to build.
  • the columns are preferably additionally fixed to the cross struts, e.g. by means of weld seams.
  • Such a frame is shown schematically in Figures 6 and 7, the middle Parts of the elements shown are omitted as they are not essential details include.
  • the elements shown are also cut away as necessary to show underlying elements.
  • the two pillars, left and right, are indicated with the reference numerals 240, 241. These can be made from relatively thin Sheet (e.g. 2 to 5 mm). They get the necessary kink resistance through the bending to a suitable column cross-section (U-shaped in Fig. 6, but what is not essential).
  • the carrier of the cleaner module encompasses the two side walls 242 or 243 and six cross struts 244A and B, 245a and B and 246A and B (only struts 244A, B in FIG. 6 and only struts 244B, 245B and in FIG. 7 246B are visible).
  • the side walls 242, 243 are formed from a relatively thick sheet (e.g. 12 mm) but relatively small compared to the columns because they are only of sufficient height H must have to accommodate the aforementioned working elements of the cleaning module to be able to.
  • the lowest limit of this height H is used for a solution according to Fig. 3A by the position of the axis of rotation of the feed roller 321.
  • the side walls 242, 243 are provided with bearings (not shown) to accommodate the work elements of Fig. 3A to be able to.
  • the cross struts 244, 245, 246 determine the working width B. They are preferred firmly connected to the columns 240, 241 (e.g. by welding seams, not shown).
  • the Side walls 242, 243 are, however, also firmly connected to the cross struts, as schematically is indicated by dashed lines at 247 in Figures 6 and 7.
  • This Connections can e.g. with screws or bolts so that the relative thin sheet of columns 240, 241 between struts 244, 245, 246 and the side walls 242, 243 firmly clamped (“sandwich construction") is what the strength of the pillars 240, 241 increased at their critical points.
  • the columns 240, 241 form parts of a substructure, which is the height of the cleaner module compared to the card (cf. Fig. 1 and Fig. 5).
  • This substructure can include other parts, e.g. Foot parts or a roller bracket to the mobility of the To ensure filling chute opposite the card.
