Definitions

  • the invention relates to a device for cleaning brush bodies according to the preamble of claim 1.
  • a cutting device for slack flat material and in particular for fabric layers has become known, in which the flat material is transported on an endlessly rotating conveyor belt and processed with a cutting tool that can be moved relative to the flat material.
  • it In order to fix the flat material in position on the conveyor belt, it is designed as an endless brush conveyor belt with a multiplicity of block-shaped brush bodies.
  • the material to be cut is covered with an air-impermeable film so that it is sucked onto the brush conveyor belt.
  • a similar cutting device is shown in DE 41 18 194 C2.
  • the brush bodies are attached to a brush holder, which in turn are connected by an encircling chain. 3 of this DE 41 18 194 C2 shows the spreading of each individual brush body in the region of the end-side deflection of the endless conveyor belt.
  • the invention has for its object to avoid these disadvantages in the previously usual cleaning of the bristle bed of a flat material cutting device and to achieve a gentle treatment of the brush body.
  • the brush bodies should be cleaned at an early stage so that the life of the bristle bed is greatly increased.
  • the basic idea of the invention is that regular cleaning of the brush bodies is facilitated in particular when they no longer have to be removed from the machine for this purpose. Regular cleaning of these parts can significantly increase the service life. Furthermore, the maintenance itself can also be carried out more effectively, since the foreign bodies do not compact so deeply in the base of the bristles, but are removed from the base of the brush at a much earlier point in time.
  • the invention therefore provides a cleaning device which is directly assigned to the flat material cutting device or integrated in it, with which a fully automatic cleaning can be carried out as required, for example daily during work breaks.
  • a cleaning device which is directly assigned to the flat material cutting device or integrated in it, with which a fully automatic cleaning can be carried out as required, for example daily during work breaks.
  • the bristle bed is constantly all in one kept clean, so that an effective work with negative pressure and a problem-free penetration of the cutting knife can take place without damaging the bristles.
  • the brush bodies are kept so narrow that they open so far at the deflection points of the conveyor belt that a nozzle element can move in between the spread brush bodies in order to pressurize the side wall with compressed air.
  • a nozzle element can move in between the spread brush bodies in order to pressurize the side wall with compressed air.
  • each brush body which is generally held stationary during the cleaning process, is laterally enclosed and pressurized with compressed air.
  • the brush body can be effectively cleaned of foreign bodies.

  • Such a cutting device consists, as shown in FIG. 1, of a bristle bed 2 for forming a material support surface or a cutting table and in particular for forming a support surface for a fabric package as a cutting base.
  • the bristle bed 2 consists of a multiplicity of individual brush bodies 3, 3 ′, 3 ′′, which are fastened on a brush holder 4.
  • the brush holder 4 is in turn connected to a conveyor device 5, which in the exemplary embodiment is designed as an endless chain with individual chain links 6.
  • the endlessly rotating conveyor chain 5 runs at both ends of the cutting device via an upper sprocket 7 and a lower sprocket 8.
  • the width of the brush bodies 3 is kept relatively narrow, where b £ ? Can be 30 mm wide.
  • the height of the brush body 3 is, for example, h fe 40 mm.
  • the entire table length can be, for example, greater than 4 m.
  • the two sprockets 7, 8 have a relatively small chain radius r ⁇ 50 un, with a distance between the two central axes 9, 10 of approximately a ⁇ ft £ 250 mm.
  • the cleaning device 15 consists of a bracket 16 on which two guide rods 17, 18 are mounted. 3 and 4, these guide rods 17, 18 extend over the entire length of the holding bracket 16, which in turn extends over the entire table width B of the cutting table.
  • the guide rods 17, 18 can again have a support 36 in the middle in the case of very large table widths, in order to prevent deflection.
  • a slider 19 is fastened in a longitudinally displaceable manner and is connected to a tube 20 for fastening a plurality of nozzle elements.
  • Moving the tube 20 with the nozzle element 14 located thereon is thus possible transversely to the cutting table.
  • These air outlet openings are designed in such a way that the air exiting there strikes the side walls of the brush body 3 at an oblique angle ⁇ and thus blow the foreign bodies located in the inner region out of the brush body.
  • the nozzle can be designed so that the angle ⁇ and thus the air outlet jet changes constantly in order to reach all parts of the bristle body.
  • the nozzle elements 14 consisting of the two nozzle legs 21, 22 are pivotably or pivotably articulated on the tube 20.
  • the tube 20 with a quadrilateral cross section at a suitable position has bores 37, 38 in which the legs 21, 22 of the nozzle element 14 are clipped in and pivotably fastened.
  • An actuator 25 can perform a rotary movement of the U-shaped nozzle element 14 from its working position according to FIGS. 1 and 2 in order to pivot it by 90 °, as shown in FIG. 4. This pivoting movement is shown symbolically in FIG. 3a with arrow 26.
  • the parallel arranged nozzle elements 14/1 to 14/4 shown in FIGS. 3a, 3b in the working position can accordingly be pivoted into the folded position shown in FIG. 4.
  • the nozzle element 14 consequently folds out of the sheet plane by 90 °.
  • the brush body 3 which is stationary during the cleaning process can be moved by one position, that is to say into the cleaning position.
  • the tube 20 consequently serves as a rotary bearing for the nozzle element 14 and at the same time as a supply element for compressed air.
  • the pipe is closed at both ends.
  • the compressed air introduced into the tube 20 is introduced into all the nozzle elements 14 and in particular into the two nozzle legs 21, 22. At the extreme tip of the nozzle legs are the two nozzle outlets 23, 24, from which the compressed air is conducted into the brush body to be cleaned in each case.
  • These foreign bodies removed from the brush body can be suctioned off with a suction device, which is located behind the cleaning device 15.
  • the normal cutting operation of the cutting device takes place when the cleaning device is in a position with the nozzle elements 14 folded down as shown in FIG. 4. This enables the brush body of the cutting table to circulate freely.
  • the position of the parallel arranged nozzle elements 14 shown in FIGS. 1 and 2 are shown in the views 3a, 3b, the nozzle elements being pivoted forward by 90 ° and thus completely enclosing the brush body laterally as shown in FIG. 1.
  • the folding process therefore serves to transfer the nozzle elements into and out of the working position.
  • FIGS. 3 and 4 four nozzle elements 14 arranged next to one another are provided over the entire width B of a cutting table, not shown, which are designated by 14/1 to 14/4. The same distance between the elements is designated a2.
  • the overall width of table B is shown in Fig. 3a.
  • the first nozzle element 14/1 is located on the left edge of a cutting table, not shown.
  • the nozzle element 14/4 shown on the extreme right in FIG. 3b is in a Distance sl from the right edge 28 of the cutting table, this "sliding path Sl" corresponds approximately to the distance a2, that is to say the distance between the nozzle elements.
  • the pipe 20, on which the individual nozzle elements 14 are located is now shifted to the right by the distance sl indicated by "sliding path" during the cleaning process of a brush body 3, so that the nozzle moves 14/4 is now on the right edge 28 of the cutting table.
  • an actuator 29 is provided for carrying out the longitudinal movement, consisting of a piston-cylinder unit which acts at point 30 on the fastening tube 20 for the nozzle elements.
  • the nozzle elements can thus run across the entire width of the cutting table.
  • the tube 20 is pressurized with compressed air, which emerges at high pressure and high speed via the nozzle ends of the nozzle elements 14 and thereby tears out the foreign bodies located in the brush bodies 3.
  • the entire width of the cutting table in the length of a complete brush body 3 can thus be cleaned of foreign bodies. This process can be carried out by moving the nozzle element back and forth several times with the brush body stationary.
  • the nozzle elements are pivoted back by 90 ° as shown in FIGS. 3b and 4.
  • an actuator 32 is provided for performing the rotating or swiveling movement.
  • Corresponding push rods connect the individual nozzle elements 14/1 to 14/4 in order to carry out a common pivoting movement into the position according to FIG. 4.
  • the two nozzle legs 21, 22 according to FIG. 2 fold 90 ° out of the image plane according to FIG. 2 by rotating the tube 20.
  • the cutting table can be clocked further by a brush body, after which the nozzle elements are swiveled outward again in order to clean the brush body that follows. This process is repeated until the entire cutting table with all of its brush bodies arranged one behind the other has passed through the cleaning device.
  • the width of the nozzle element 14 can also extend across the entire width of the cutting table or of the brush element or parts thereof, thereby eliminating the need for lateral displacement.
  • the cleaning device 15 with the nozzle elements 14 can also perform a linear retraction movement to the brush element instead of a pivoting movement, the movement also being possible during the cleaning process in order to wipe off the side walls 33, 34 in terms of compressed air.
