Definitions

  • the method can be adapted very quickly to new patterns if the base part is moved using a freely programmable, at least 2-axis positioning device, in particular a freely programmable, preferably 2-axis industrial robot.
  • the gap exists between the edge of the openings and the transport device, but in particular the gap is even so large that the device is completely spaced from the rear side of the base part.
  • the front ends of the tufts may contact a profiled pressure member during or after loading of the base member to provide a profiled brushing surface.
  • the brush surface is the front side working surface of the brush formed by the bristle ends.
  • This pressure part can either already be present during the plug and serve as a stop or pressed against the bristles after the plug, so that they rest against the pressure part and image the shape of the pressure part.
  • the bristle tufts protruding from the back of the openings of the base part are cut off after being pushed in according to the preferred embodiment.
  • the tolerances of the individual bristle lengths are thereby complete Compensated, because on the front can be done on the pressure part a precise length adjustment, the back is then simply cut off.
  • the device according to the invention also comprises a station in which the base part for the sequential piercing is moved at least in two directions in order to align the opening to be filled with the bristle tufts to be filled, this station in particular having a freely programmable, preferably 2-axis industrial robot Has shift of the base part.
  • FIG. 1 It can be seen that a transport device 18, which will be explained in more detail below, conveys individual bristle tufts 16, which are pushed by a device from the transport device 18 into the openings 14 from the rear side of the base part 12.
  • a counterpressure part 36 complementary to the pressure part can be provided on this rear side so that the bristle tufts 16 can be axially fixed between the pressure part 32 and the counterpressure part 36 as far as possible without play.
  • bristle tufts 16 are attached at the back. This attachment is done for example by welding.
  • the guide member 26 it is preferable (not limiting) for the guide member 26 to be supported on the base member 12 to provide support and sealing.
  • FIG. 2 Further details of a possible embodiment of the station of the device according to the invention, in which the bristle tufts 16 are separated and transported to the base part 12.
  • the device has its own station with a magazine 42, in which a bristle supply 44 is housed.
  • the bristles are aligned in magazine 42 parallel and ungrouped housed. They are pressed by adapted pressure means in the direction of the transport device 18.
  • the separation of the bristle tufts 16 thus takes place laterally to the longitudinal extension of the bristles, which in the present case would be perpendicular to the plane of the drawing.
  • the receiving opening 50 When the receiving opening 50 is filled with bristles, it is pivoted clockwise and in the in FIG. 2 shown position moves.
  • a guide plate 52 which conforms to the shape of the plate 48, ensures that no bristles can fall out of the receiving opening 50.
  • the bristle tufts 16 are pushed directly into the base part 12 directly, without the interposition of a carrier plate or the like. It should be noted that the individual bristle tufts are removed sequentially from the magazine 42 and transported with the tuft picker to their final position before impact. A transfer to subcarrier is avoided here.
  • the base portion 12 has numerous openings 14 which must be successively filled with bristle tufts 16, the base portion 12 is moved in two directions X, Y. In order to be filled openings 14 are aligned with the receiving opening 50 and the next bristle tufts 16 to be injected.
  • the corresponding station preferably has a so-called X-Y carriage, on which the base parts 12 can be fastened and moved in one plane.
  • a so-called X-Y carriage is a simple embodiment of a freely programmable, at least 2-axis positioning device, in particular a freely programmable 2-axis industrial robot.
  • FIG. 3 shows the magazine 42 with the tuft stock 44 in perspective view. To clarify the entire station several parts have been omitted.
  • FIG. 3 further shows a bristle tufts 16, which is being pushed by the device 20 into an opening of the base part 12.
  • a holder 54 positions and locks the guide member 26 to an alignment unit, for example an XY carriage, over which the alignment of the base part 12 to the receiving opening 50 takes place.
  • the loading with the bristle tufts 16 is in FIG. 5 shown in more detail. It can be seen that the bristle tufts 16 accommodated in the transport device 18 are spaced from the rear side of the base part 12 before being inserted into the openings 14. The transport device is spaced from the base part 12 in the region of the openings 14 via a gap 60 with the gap thickness d. This gap 60 is bridged by no guide member or the like.
  • the openings 14 are preferably provided on the back with a flared chamfer 62.
  • the base part 12 has a depression 64 in the region of the openings 14 on the rear side. In this recess 64, the lid member 14 is introduced or molded.
  • the transport device 18 is designed so that during the insertion of the bristles into the openings 14 in the transport device 18 exclusively axial pressure (that is, pressure in the bristle longitudinal direction) is exerted on the bristle tufts 16 to be introduced. That is, the wall around the receiving opening 50 is rigid, no radial clamping force is exerted on the bristles. The only clamping force is achieved by the bias in the bristle supply 44, which is forwarded so to speak in the receiving opening 50 when separating the bristles.
  • the cutting of the bristle tufts 16 preferably takes place in a separate station of the device according to the invention, preferably by means of a heated tool.
  • FIG. 6 shows an embodiment of such a heated tool 70, which comprises a current-carrying, hot wire.
  • This wire is moved substantially parallel to the back of the base part 12, as close as possible to the base part 12 along and separates the protruding bristle ends. Bristles can also partly melt together.
  • FIG. 7 shows the effects of heat on not yet cut bristle tufts 16, which merge together. In addition, however, the already separated ends of remaining in the base part 12 bristle tufts 16 merge, which is advantageous for positioning and attachment.
  • FIGS. 8a to 8c While in the Figures 5 and 6 a substantially circular cross-section wire as a tool 70 is shown in the FIGS. 8a to 8c to see an alternative embodiment with a so-called flat wire. This also current-carrying, heated wire is placed like a knife obliquely to the bristles to be separated.
  • the bristle tufts 16 are not laterally supported in the region of their interface. Also, the tool 70 is not supported in the region of the base part 12, so that no wear occurs during cutting. The cutting takes place, so to speak, without support.
  • the bristle tufts 16 are either laterally only through the base part 12 (see FIGS. 8a to 8c ) or held by the base part 12 and the guide member 26. In the axial direction, the bristle tufts 16 are positioned between the pressure part 32 and the counter-pressure part 36. This positioning should, but not in a limiting sense, be ensured even during cutting.
  • the fixing of the bristle tufts 16 on the base part 12 is, as I said, either by welding and / or by gluing and / or by casting, for example during the production of the cover part 40th Das Lid portion 40 may in particular have rearwardly projecting cleaning projections 80 to form a tongue cleaner. Alternatively, the supplied cover part 40 can be subsequently pressed or glued, even using the aforementioned sacrificial structures.
  • openings 14 must be closed by a bristle tufts 16. It may, as already mentioned, even one or the other opening 14 remain unfilled. When later gluing or potting or injection molding, the corresponding opening 14 is then closed.
  • FIG. 6 it is also possible that some openings with an elastomeric profile member 82 are fitted, as exemplified in FIG. 6 is shown.
  • the corresponding opening 14 in the base part 12 corresponds to this one-piece profile part, whose cross section is significantly larger than that of a bristle tufts 16.
  • the profile part 82 can serve as a massage extension for gums or the like.
  • the profile part 82 may either be prefabricated and then mounted in the opening or molded immediately in / at the opening.
  • FIG. 9 a device for producing the brush according to the method described above is shown.
  • This device is designed as a tool, for example with a rotating table 100.
  • each bristle tuft 16 is moved individually to the base part 12 (in this case the brush body 10) via the removal device 48 and the transport device 18, wherein previously the brush body 10 is placed on the guide member 26.
  • a magazine with empty guide parts 26 may be present and is not shown here for clarity.
  • each individual bristle tuft 16 is stuffed into the associated opening 14 by moving the laterally held guide part 26 in the X and Y directions.
  • the finished assembled base 12 is then moved to the tool table 100 and attached to this.
  • the rotating tool table 100 transports one or more of the base parts 12 to a station in which Figure 1c Pressure and counterpressure 32, 36 align the tufts.
  • the tufts are cut off at the back by means of the tool 70. This cutting can be done in a subsequent station or in the Station occur in the pressure and counter-pressure member 32, 36 are applied for the first time.
  • the bristle tufts 16 are attached on the back, for example under the action of heat.
  • lid part 40 is sprayed on.
  • the finished brushes are removed and stacked, for example.
  • the transport of the guide members 26 into the first station is not explicitly shown.
