Definitions

  • the invention relates to a device for compacting bristle bundles for the production of bristle goods, a bristle goods manufacturing machine with such a device and a method for compacting bristle bundles.
  • the brush manufacturing machine is characterized in that the feed device is designed for an independent, controllable feed of the individual bristle strands, that the feed device has a stepwise positionable conveyor with holes for bristle strands or bristle bundles, that each feeds for the bristle strands to a step position of one of the holes are provided in the conveying means, and that one or more shearing devices which interact with the conveying means are arranged in the bristle strand feeds for cutting the bristle strands to length.
  • bristle filaments are separated from a supply of loose bristle filaments in the form of bristle bundles using a supply means, for example a bundle separator.
  • the means of provision used can be used for this purpose Have bundle notches with which the provision means are guided past the supply of loose bristle filaments. A certain number of bristle filaments end up in the bundle notches. The bristle filaments arranged in a bundle notch together form a bristle bundle.
  • the bristle bundles are still unshaped and not compacted.
  • the filament density of the bristle bundles located in the bundle notches is still comparatively low and the bristle bundles do not yet have the shape that they will later have on the finished bristle product.
  • a device for compacting bundles of bristles which has a provision means, in particular a bundle divider, with bundle notches, a number of compression receptacles for bristle bundles that at least correspond to the number of bundle notches and a compaction means for each of its compaction receptacles , wherein the compaction receptacles are set up to remove bristle bundles from the bundle notches of the providing means and the compaction means are set up to compact bristle bundles positioned in the compaction receptacles.
  • bundles of bristles can be separated from a supply of loose bristle filaments and provided in a still uncompacted form.
  • the still uncompacted bristle bundles can first be removed from the bundle notches of the provision means in one step and then with the help of the compaction means they can be compacted to a desired degree of compaction, which the bristle bundles will later have in a subsequent processing step and/or on the finished bristle products should . This enables particularly efficient production of bristle products.
  • the compression receptacles of the device are formed in a removal plate or in two or more removal plates of the device.
  • the compaction receptacles can each have an insertion opening through which bundles of bristles and/or compaction means can be inserted into the compaction receptacles.
  • the insertion openings can each be aligned transversely or at right angles to a longitudinal axis of the respective compaction receptacle and/or transversely or at right angles to a longitudinal axis of bristle bundles arranged in the compaction receptacles. In this way, it is possible to first remove the bundles of bristles from the bundle notches of the provision means in a relative movement carried out transversely or at right angles to their longitudinal axis and then to compact them in the same direction.
  • the compaction can be carried out, for example, by the compaction means passing through the insertion opening of the compaction receptacles into the compaction receptacles in a compression movement aligned transversely or at right angles to the orientation of the longitudinal axes of the bristle bundles arranged in the compaction receptacles, where they then act on the bristle bundles located therein in a compressive manner.
  • the insertion openings of the compression receptacles can be limited by insertion chamfers.
  • the insertion chamfers enable gentle introduction of the compaction agent into the compaction receptacles of the device and can help Damage to the sealing agents and/or
  • At least one compaction means has a sharp-edged transition between its flanks and its end face facing the compaction receptacle to which the compaction means is assigned. Due to the sharp-edged transition between the flanks and the end face of the compaction means, the compaction means can be designed to fit precisely and tightly against an inner wall of the compaction receptacle.
  • the sharp-edged transition between the flanks and the end face of the compaction means can prevent bristle filaments, which are arranged in the compaction receptacle, from getting past the compaction means and out of the compaction receptacle when the previously explained relative movement for compacting the bristle bundles is carried out.
  • At least one compaction means can be smoothed on at least one flank that adjoins its end face of the compaction means facing a compression receptacle and/or hardened.
  • the flank can, for example, have a surface roughness of Ra 0.01-1.6, preferably Ra 0.01-0.04, and/or a hardness, in particular a surface hardness with a depth of 1.2-1.8 Rht 55-63 HRC, preferably from 60-63 HRC.
  • the compaction means can each have a cross section whose measurable width is smaller than a width of a cross section of the compression receptacle assigned to them, arranged in the same cross-sectional plane. In this way, the compaction means for compacting bristle bundles can be introduced through the insertion openings into the compaction receptacles.
  • At least one compaction means of the device can have an undersize of 0 pm to 50 pm, measurable in a width direction of the compression receptacle assigned to it, in particular an undersize of 0 pm to 20 pm, to a clear width of an insertion opening of the compression receptacle assigned to it, measurable in the same width direction.
  • the undercut allows the compression receptacle to have a cross section that is laterally expanded with respect to an insertion opening of the compression receptacle and/or with respect to a longitudinal axis of the compression receptacle. This can promote the formation and compaction of bristle bundles with a cross-sectional shape, for example which deviates from a circular cross-sectional shape and/or is asymmetrical.
  • the device can have at least one target plate downstream of the compaction receptacles, which includes target receptacles for receiving the compacted bristle bundles.
  • the target plate can be designed, for example, as a cassette and/or as a transport holder for compacted bundles of bristles. After equipping its target holders with compacted bristle bundles, the target plate can then be fed to a downstream process step for further processing of the bristle bundles.
  • the target receptacles of the target plate can have insertion chamfers.
  • the insertion bevels can simplify the transfer of the compacted bristle bundles from the compaction receptacles into the target receptacles.
  • the target receptacles of the target plate can be arranged in a hole arrangement which corresponds to an arrangement of bristle bundles on a bristle carrier of a bristle product to be produced.
  • the bristle bundles ready in the target plate not only with the desired degree of compaction, but also in the arrangement that the bristle bundles will later assume on a bristle carrier of the bristle product to be produced.
  • At least one removal plate of the device can have compression receptacles that are arranged in a hole pattern that corresponds to at least a partial hole pattern of the hole arrangement of the target receptacles of the target plate. In this way, it is possible to transfer the bristle bundles held in the compression receptacles of a removal plate of the device directly into target receptacles of the target plate after they have been compacted. If the compaction receptacles of the device are distributed over more than one removal plate, it is possible to equip the target receptacles of the target plate one after the other in subgroups with bundles of bristles.
  • the bundles of bristles are preferably removed from the bundle notches of the provision means in a removal movement and/or compaction movement which is oriented transversely or at right angles to their longitudinal direction and/or are then compacted using the compaction means.
  • the subsequent transfer of the compacted bristle bundles from the compaction receptacles into the target receptacles of the target plate can then take place in the longitudinal direction of the longitudinal axes of the bristle bundles and thus transversely or at right angles to the removal direction and/or the compaction direction.
  • the transfer device can have at least one sliding pin with which the bristle bundles can be pushed in the longitudinal direction of their longitudinal axes from the compaction receptacles into the target receptacles of the target plate.
  • the transfer device preferably has a sliding pin for each compression receptacle.
  • the at least one push pin preferably has the same cross section as the receiving opening to which the push pin is assigned and/or like a bundle of bristles compacted therein.
