Definitions

  • the invention relates to a method according to the preamble of claim 1. Furthermore, the invention is directed to a device according to the preamble of claim 10.
  • the bristle ends are either immersed in a solvent at a defined rate and pulled out again, and the solvent bath is subjected to ultrasonic vibration (DE-A-30 07 761) or it a plastic monofilament is immersed in a viscous liquid and coated with a jacket which tapers towards the end by pulling out the corresponding speed profile (US Pat. No. 2,207,158).
  • Another type of method for producing conical bristles is based on an endless monofilament which, after extrusion, is intermittently tapered by changing the rate of stretching (DE-C-8 41 483, US-A-2 341 823) and cut into bristles in the region of the taper , or hollow monofilaments are produced (US-A-3 184 822) and these are thermally compressed towards the end after cutting.
  • bristles are known in which the bristle jacket is profiled (US-A-2 317 485) and / or roughened (US-A-2 862 284) to improve the cleaning effect.
  • the invention is concerned exclusively with a mechanical method.
  • planing, milling and grinding possibly also in combination with one another, are known.
  • the longer bristles are firstly arranged in rows by wedge-shaped inserts displaced outwards, the shorter bristles gripped laterally, cut and ground at their ends, after removing the inserts the longer bristles are ground (EP-A-0 078 569).
  • US-A-2 227 126) with combined milling and grinding machining, the toothbrushes or their bristles are guided over the outer surface of a plurality of rotating disk tools, the outer surface of which is recessed and differently profiled.
  • the bristle contour is achieved by a corresponding path of movement of the brushes.
  • strips are arranged in comb-like manner between the individual rows of bristles, which have different heights and above which the bristles are cut.
  • further bars can also be inserted perpendicular to the strips.
  • the invention is based on a known method (DE-C-9 58 016, DE-A-29 22 289), in which the bristles cut to length are processed at their ends by a flat grinding surface rotating about two axes.
  • the grinding surface is arranged perpendicular to the bristles. Due to the circular movement of each point of the grinding surface, the bristles should be pressed accordingly to ensure that each bristle is rounded evenly at its end.
  • the pressure can be varied (DE-C-9 58 016) by the holder fixing the brush being adjustable by means of threaded spindles and threaded nuts, initially with a stronger one Pressure and accordingly greater deflection of the bristles started and then the holder is moved away from the grinding surface.
  • the invention has for its object to further develop the aforementioned method in such a way that a perfect end machining with any brush contour and, if necessary, machining of the bristle jacket is possible in a zone extending from the bristle end in the direction of clamping. Furthermore, the object of the invention is to propose a device suitable for carrying out the method.
  • the bristles are clamped in as short cuts or as part of endless monofilaments with a distance from the bristle ends corresponding approximately to the final length.
  • This can be a clamping device used in the production process for brush production, which clamps the bristles in the configuration relevant for the finished brush fixed, or it is the brush body or a part of the same, in which the bristles have been inserted during the manufacturing process.
  • the bristles are then supported at a distance from the clamping point after being clamped, cut to the desired length on this support, which also forms a shearing surface, and then machined, in particular rounded, at the ends by grinding.
  • the grinding pressure required for the end machining is preferably generated by adjusting the grinding surface in the direction of the bristle ends, the grinding pressure possibly being varied during the machining.
  • the grinding pressure and thus the machining result depends largely on the length of the bristles - the bristles more or less evade the grinding pressure depending on the length and position within the bundle or the brush the bristles are additionally supported laterally between their clamping and the free bristle ends.
  • This lateral support is formed by the shear surface for cutting. It can be varied, for example to ensure the same free length for all bristles and thus to ensure a uniform grinding pressure on all bristle ends.
  • the machining result itself namely the type of rounding
  • the machining result itself namely the type of rounding
  • the bristles or Bristle bundles are not arranged on the brush body perpendicular to the clamping plane, but extend at angles that deviate from 90 degrees. It is often the case that the bristles or Bristle bundles run at different angles.
  • the bristles are laterally supported at a distance from the clamping plane and laterally displaced by means of the support such that they are perpendicular to the clamping plane or to the grinding surface between the support and the bristle ends run, and then the grinding surface is delivered.
  • the bristles or bundles of bristles are not only supported laterally according to the above-mentioned embodiment within the scope of their predetermined angular position, but are also brought into a position perpendicular to the grinding surface by lateral displacement of the support, that is to say bent relative to the clamping plane at the complementary angle, so that all bristles be acted upon by the grinding surface in the same position. After grinding and after the lateral support has ceased, the bristles return to their originally specified angular position over their entire length.
  • the above-mentioned process variant can be combined with the cutting process in such a way that the bristle ends are first cut to the desired size immediately after the lateral displacement immediately above the support, then the support is moved parallel to the bristles while increasing the distance to the bristle ends and the grinding surface is then delivered.
  • the bristles or bristle bundles Due to the support of the bristles or bristle bundles carried out in the manner according to the invention, they can be cut to the same length despite different angular positions, the bristles being supported directly below the cutting plane. After cutting, the bristles become larger Distance from the bristle ends supported laterally and then ground at their ends.
  • the bristles or the bristle bundles have different free lengths in order to form a contoured brush surface
  • a uniform processing result for all bristles is ensured according to a further embodiment of the invention in that the bristles depending on their length between the clamping plane and the lateral support perpendicular to their extension laterally deflected until the ends of all bristles lie in one plane, and then the grinding surface is delivered.
  • the method according to the invention also allows processing of the bristle jacket in the region of the bristle ends, for example in order to roughen the bristles, to sharpen them or the like, for example by injecting the abrasive surface, preferably suddenly, to such an extent that the bristles are bent in one direction and with it Bristle jacket of the grinding surface adjoining the bristle end.
  • the length of the bristle jacket lying against the grinding surface and thus the machined length of the bristle can in turn be influenced by the lateral support of the bristles. The smaller the distance of the support from the grinding surface, the smaller the bent bristle length.
  • the grinding surface and the clamping plane are moved parallel to each other from a position in which the grinding surface is located on the side of all bristles and the distance between the two is smaller than the bristle length such that the bristles are bent against the direction of displacement and align with the area to be processed of their jacket on the grinding surface.
  • the machining length on the bristle jacket can be preset very precisely.
  • the separate and variable-variable support of the bristles can optionally be dispensed with.
  • the invention is based on a device according to the preamble of claim 10 (DE-C-9 58 016).
  • Such a device is characterized according to the invention by the characterizing features of claim 10.
  • the support is first brought into the position which is intended for cutting the bristle ends, and then the cutting device is guided over the support and the bristles are cut in the process.
  • the support is then moved away from the bristle ends until there is a certain free bristle length.
  • the grinding wheel is then fed in and the machining process begins.
  • two or more supports can also be provided, which can be moved parallel to the bristles independently of one another and of which the supports close to the bristle ends forms the shear surface and the two together form the support during grinding.
  • the procedure can be such that the grinding member has an infeed drive which forms the device for changing the distance.
  • an embodiment of the device according to the invention is characterized in that the support can be displaced parallel to the grinding surface.
  • a device for deflecting the bristles from their extended position is provided between the clamping and the support and engages between the bristles or individual bristle bundles and can be displaced transversely to them. Since the differences in brushes with different bristle lengths are generally only within narrow limits, the bundle spacing is generally sufficient to have enough space between the bundles for the necessary deflection.
  • the device is further characterized in that the grinding member can be moved parallel to the support into the grinding position from a position next to the bristles fixed by the clamping, in which its distance from the support is smaller than the free length of the bristles.
  • the bristles can be bent from the grinding surface when the grinding member is moved into the grinding position, that they rest with part of their jacket on the grinding surface and can be processed on the jacket side in this way.
  • the support can be formed from strips which engage between the bristles or the bristle bundles in the manner of a comb.

Such a bristle 16 can only be rounded at its end, as indicated at the end 18 in FIG. 4b. In addition, the bristle 16 can be roughened on its section 19 near the rounded end 18 (FIG. 4c). Instead, it is possible to sharpen the bristle 16 towards the end of the section 20 in order to obtain greater flexibility in the region of the end (FIG. 4d), it also being possible to round the tip 21 at the end of the conically tapering section 20 ( Figure 4e).
  • FIG. 5a shows the usual machining process when rounding the bristle ends.

With this displacement movement, the rods 24 deflect the bundle of bristles 23 between the supports 10 and 22 to the side. The extent of the displacement movement is selected so that the ends of the bristle bundle 23 lie in one plane with the ends of the bristle bundle 9 (FIG. 8c). Then the grinding member 1 is fed in order to machine the ends of the bristles. After the grinding member 1 has moved away and the supports 10, 22 and the rods 24 have been moved out, the bundle of bristles 23 returns to the extended position (FIG. 8d), so that the ends of all the bundles of bristles 9, 23 are rounded uniformly.
