Definitions

  • the invention relates to a method for the production of a segment of a roller brush, the segment itself and roller brushes formed by such segments.
  • Roller brushes composed of segments are known and proven in various embodiments. Were the bristles of a segment previously held mostly by a compressed, in a cross-section U-shaped metal profile, modern segments of roller brushes are often made entirely of plastic by a bristle ends holding U-profile is formed, for example in the WO 98/20773 explained.
  • the object of the invention is to provide a production method for a segment of a roller brush, by means of which segments of a complex spatial structure can also be produced in a simple and cost-effective manner and which, owing to their spatial structure, offers a variety of design options in terms of their design offer a roller brush.
  • the method according to the invention has a number of advantages.
  • a blank By arresting a bristle mat in a first process step, a blank is created, which can also be stored in a dimensionally stable manner largely.
  • a very great dimensional stability can be achieved by the measure that the arresting takes place by a material application on both sides and / or a material entry in the middle of the bristle mat.
  • the bristles are already optimally bonded together and the ends of the bristles can still be melted on such a dimensionally stable bristle package for further arrest.
  • Another advantage is the pressing in that the axial flat sides of the profile can be structured. It is particularly thought that with the profiling in the press on both sides of the profile axially projecting driving pins and adjacent corresponding recesses and / or multiple arrangements of corresponding recesses and cam pins are formed over the circumference in a waveform corresponding to the uniform division, in a side view on the underside recesses in each case a driver pin on the upper side or on the underside driver pins on the upper side in each case a recess is arranged.
  • Such a segment of a roller brush in particular produced according to the above-described method, in which a pressed plastic profile forming a bristle stocking in a circumferentially uniform pitch axially troughs and wave peaks forms, in which the profile on both sides axially projecting driving pins and adjacent corresponding recesses and / or Multiple arrangements of corresponding recesses and cam pins circumferentially in one of the waveforms corresponding uniform pitch, wherein in a side view on the underside recess on the upper side in each case a driver pin or on the underside driver pins on the upper side in each case a recess is arranged, can be advantageously used in many ways.
  • the driving pins and the recesses on the upper side of the profile are arranged symmetrically on wave crests and the underside symmetrically in wave troughs. This corresponds to the division of driving pins and recesses over the circumference directly with the formation of wave crests and troughs.
  • the driving pins and the recesses are conical. In this way, depending on the choice of the wedge angle, after insertion of the driving pins in the corresponding recesses a nearly permanent coupling of two segments can be achieved.
  • roller brushes or their segments driver which lock positively with a drive shaft. If such a driver is provided, which projects radially inward on the profile, this is preferably symmetrical to an angle bisector of an angle formed, which is spanned between a driving pin and an adjacent recess with respect to a central axis.
  • This arrangement of the driver has the consequence that segments according to the invention can also be mirror-inverted against each other under the interlocking of cam pins and recesses, continue to come to rest driver on the segments.
  • a roller brush can be assembled, in which segments in the same orientation joined together form a large bristle density, wherein the drive pins lock a first segment in the recesses of a second, subsequent segment. If segments mirrored together under locking of the driving pins in the recesses joined together, a roller brush is formed by low bristle density, as then wave crests lie against each other and the center planes of the segments and thus the bristle trimmings are spaced correspondingly far. Such can be supported by a correspondingly long training of the driving pins, which may possibly be provided with an excess length for a large spacing of adjacent segments.
  • Another way of arranging the segments is that they are rotated by 60 ° from each other and set together form a transport arrangement in which the drive pins just do not engage in recesses.
  • Fig. 1 shows in an isometric view a segment 1, which in a plan view actually has a circular cross-section and the bristles not shown radially outwardly throughout the drawing protrude.
  • the bristle-holding plastic profile 2 of the segment 1 in a uniform pitch of 120 ° has a waveform with three wave crests 3-5 and three troughs 6-8, which protrude a center plane 9 in both axial directions with the same amplitude a, see. Fig. 3 ,
  • the preferably conical driving pins 12-14 and 18-20 allow by locking in the corresponding recesses 15-17 and 21-23 entrainment successive segments 1 in the direction of rotation, as well as, with a correspondingly long axial training, a more extensive axial spacing of segments 1 of a roller brush.
  • pairs of driving pins 12-14 and recesses 15-17 on the wave crests 3-5 are respectively centered on the crest of the wave crest 3-5, respectively on the underside the driving pins 18-20 and Recesses 21-23 symmetrical to the bottom of troughs 6-8.
  • the side view acc. Fig. 2 in that the driver pins 12-14 of the upper flat side 10 are arranged above the recesses 21-23 in the lower flat side 11 and vice versa, the recesses 15-17 in the upper flat side 10 via the driver pins 18-20 of the lower flat side 11.
  • a driver 24 is further formed, which can lock positively with a shaft.
  • This driver 24 is symmetrical over the circumference to a driving pin 12 and a Recess 15 arranged, here the driver pin 12 and the recess 15 enclosing. In general, it can be formed symmetrically to an angle bisector of an angle which is spanned between the one of a driving pin and an adjacent recess from a central axis of the segment 1 ago.
  • the symmetry properties of the segment 1 allow various designs of roller brushes, which are further explained below.
  • Fig. 4 shows the juxtaposition of two similar segments 1,1 ', wherein the upper segment 1' opposite to the Fig. 1 rotated by 180 ° or mirror-inverted placed on the lower segment 1.
  • the drivers 24, 24 ' lie directly above one another and are the segments 1, 1' with wave crest 3 at wave crest 3 'and successively and so is a roller brush with a due to the axial spacing of the segments 1,1' low density of Bristle set trained.
  • a roller brush with a bristle set high density is obtained if gem.
  • Fig. 6 Individual segments in the same orientation together, optionally spaced by the driving pins 12-14. In this arrangement of the segments 1, 1 ', the wave crests 3 lie below the wave crests 3' located above them, as a result of which a roller brush of high packing density is achieved, in particular if an upper flat side 10 is in immediate contact with a lower flat side 11 '.
  • conical pins and recesses are provided, can be created by the choice of a small wedge angle, a nearly permanent connection between the segments 1,1 '.
  • FIGS. 9 and 10 show not to scale in a section in the circumferential direction cutouts of segments 26 to 28. These segments 26 to 28 are each provided with a multiple arrangement 29 to 31 corresponding recesses and driving pins.
  • Each multiple arrangement 29 to 31 has a comparatively long driving pin 32 with underlying, corresponding recess 33. Possibly. Mit Spotify 32 may also be provided with a tip or rounding for a simplified insertion into, for example, a recess 34 of another segment 28.
  • driving pin 32 two further recesses 35,36 are provided here by way of example, the driving pin 32 enclosing.
  • driving pins 37, 38 of the segment 28 interlock in the recesses 35, 36.
  • segments 27,28 permanently connected to each other.
  • the drive pins 41, 42 provided with a chamfer 39, 40 each form a radially projecting annular shoulder 43, 44, which engage behind corresponding undercuts 47, 48 when introduced into the corresponding recesses 45, 46, for example of the segment 27.
  • the driving pins 41,42 are still provided with slots 49,50 in the embodiment.
