Definitions

  • the present invention relates to a method for the production of brushes, in particular toothbrushes, in which the bristle bundle is divided in a first direction of movement from at least one bristle supply from a single compartment element which lies with its outer circumferential surface sealingly against an opening of the bristle supply and is attached to at least one bristle carrier from the Compartment element can be removed in a second direction of movement, after several bristle bundles have been divided with one compartment element in the first direction of movement, the compartment element is stopped and these bristle bundles are removed from the compartment element in the second direction of movement at the same time.
  • Such a method is from DE 28 49 510 A1 or EP 0 405 204 A2 known.
  • the present invention is based on the problem of improving the generic method in terms of its speed and performance.
  • the dividing element is stopped and the bristle bundles held on the dividing element are detected in a second direction of movement, preferably orthogonal to the first direction of movement, and removed at the same time. Simultaneously within the meaning of the present invention means that the bristle bundles are removed essentially at the same time, namely that the bristle bundles initially provided via the dividing element in a first direction of movement are removed from the dividing element before the latter is set in motion again to divide further bristle bundles.
  • the bristle bundles removed in the second direction of movement are finished bristle bundles, which can be seen as individual bundles on the finished brush or form the subset of an enlarged bristle bundle in which several bristle bundles with an identical or substantially identical number of bristle filaments are combined.
  • the bristle bundles produced in this way are removed from the dividing element for attachment to the bristle carrier. This means that the bristle bundles are removed from the dividing element.
  • the bristle bundles can either be gripped in a manner known per se with a stuffing tool and attached directly to the bristle carrier. Alternatively, the bristle bundles can also be transferred to a holder for further preparation of the bristle bundles for later attachment to a bristle carrier.
  • the bristle bundles are simultaneously introduced into at least one hole field pattern in the second direction of movement, which pattern corresponds to a bristle arrangement of a single bristle carrier.
  • the hole field pattern in the sense of the invention is a pattern of holes which are provided in an arrangement corresponding to the size, number and relative orientation of the bristles of the finished brush. Since the bristle bundles are introduced into the hole field pattern (s) at the same time in the second movement, such a hole field pattern can be stuffed more quickly with bristle bundles.
  • the simultaneous tamping of several perforated field patterns, which are formed in a common perforated field plate, can be carried out in a simplified manner and, moreover, the most time-consuming step of preparing the bristle bundles for subsequent fastening can be accelerated by overmolding with plastic compound.
  • the bundles of bristles are preferably held in the second direction of movement via a common tamping tool and simultaneously introduced into different holes of the at least one hole field pattern.
  • the stuffing tool required to carry out this preferred method can be designed with only a slightly higher mass than a stuffing tool for stuffing just a bundle of bristles, despite the increased output.
  • the bundles of bristles are held in the second direction of movement by a plurality of stuffing tools and are simultaneously introduced into different holes of the at least one hole field pattern.
  • the different stuffing tools are preferably coordinated with one another in such a way that the still functional stuffing tools can guarantee production even in the event of failure of one or more stuffing tools.
  • the bundles of bristles are introduced into corresponding holes of different hole field patterns in the second direction of movement at the same time.
  • This preferred Process management facilitates the mass production of a large number of brushes with an identical perforated field pattern.
  • the relative movement between the perforated field pattern and the tamping tool in a direction essentially transverse to the extent of the holes in order to provide empty holes for the tamping device, which is required for tamping a perforated field pattern includes a large number of perforated field patterns, the corresponding holes of which are each stuffed at the same time with bundles of bristles .
  • the bundles of bristles are introduced simultaneously into the holes of the at least one hole field pattern in the second direction of movement while maintaining their lateral spacing.
  • This preferred development of the method according to the invention initially simplifies the structural design of the device required to carry out the method.
  • the preferred method is particularly suitable for preparing bundles of bristles which are stuffed into a hole field pattern, the holes of which are at an identical lateral distance from one another.
  • the lateral spacing of the recesses provided on the dividing element and receiving the bristle bundles corresponds precisely to this lateral spacing of individual holes in the perforated field pattern.
  • the prepared bristle bundles removed from the compartment element at the removal position are introduced directly into adjacent holes of the hole field pattern without changing their lateral spacing.
  • the movement in the second direction of movement can be an exclusively linear movement, which results in a quick and simple process control.
  • the bundles of bristles are held in the second direction of movement by a common tamping tool and at the same time introduced into a single hole in the hole field pattern.
  • the bundles of bristles are preferably conveyed to the mouth of a hole while maintaining their lateral spacing and are moved towards one another when they are introduced into the hole.
  • the bundles of bristles slide off the surface of a funnel-shaped opening of the hole when they are introduced into the hole. This ensures that the bristle bundles are safely introduced into the hole with a simple configuration of the device for carrying out the method.
  • Figure 1 and 2 each show schematically essential parts of a device for carrying out the method, which has a bristle storage container 2, a circular-arc-shaped partition element 4 and a tamping tool 6.
  • the compartment element 4 lies with its outer circumferential surface 8 in a sealing manner against an opening of the bristle storage container 2. Furthermore, the compartment element 4 has two recesses 10a, 10b positioned next to one another.
  • bristle filaments 12 are removed from storage container 2 by means of partition element 4.
  • a certain number of bristle filaments 12 are only removed from the bristle storage container 2 when the recesses 10a, 10b of the compartment element 4 are moved past the opening of the bristle storage container 2.
  • the bristle filaments 12 are thereby divided into two different bristle bundles 14 in a controlled manner.
  • the bristle bundles 14 are guided to a stuffing tool 6 with a continuous movement in the direction of the arrow P.
  • the circular dividing element 4 ends the first direction of movement only when the bristle bundles 14 have reached a position in which the bristle bundles 14 can be introduced simultaneously in a linear movement into holes 16 of a bristle carrier 18 provided for them.
  • this second movement which is essentially orthogonal takes place to the first movement, ie essentially at right angles to the instantaneous movement of the bristle bundles 14 immediately before the stopping of the dividing element 4 for removing the bristle bundles 14, the bristle bundles 14a, 14b are spaced from one another so that the distance between the bristle bundles 14a, 14b, corresponds to the distance between the holes 16a, 16b and the distance between the recesses 10a, 10b (at right angles to the direction of movement of the stuffing tool 6).
  • the embodiment in Figure 2 differs from the one in Figure 1 embodiment shown in that the bristle bundles are introduced into a single perforated field plate 20.
  • the perforated field plate 20 can then either be fastened directly to a bristle carrier, or it serves as a holder while the bristle bundles are fastened to a bristle carrier.
  • Figure 2 - as in the Figures 4 , 5 - The introduction of the bristle bundles into the perforated field plate 20 is shown schematically simplified. In fact, the bundles 14a, 14b are removed from the stuffing tool and introduced into the perforated field plate 20 in the axial direction, that is to say perpendicular to the plane of the drawing.
  • the compartment element 4 on its outer circumferential surface 8 will accordingly also rest against a counter surface by which the recesses 10a, 10b are closed.
  • the bundles of bristles 14a, 14b can be removed from the compartment element 4, for example, by a punch engaging in the recesses 10a, 10b.
  • FIGS 3 to 5 show further exemplary embodiments of the method according to the invention. In these figures are compared to the embodiment of Figures 1 and 2 identical parts are identified by the same reference numerals.
  • the bristle arrangement shown has two stuffing tools 22a, 22b.
  • the compartment element 4 which lies sealingly against the bristle storage container 2
  • the compartment element 4 is moved in a first circular arc-shaped movement in the direction of the arrow P.
  • bristle filaments are removed from the first recess 24b from the bristle storage container 2 and divided into a bristle bundle 26b.
  • the dividing element 4 continues to move in the direction of the arrow P, further bristle filaments 12 are divided into a bristle bundle 26a by means of the second recess 24a.
  • the bristle bundles 26 are guided in the direction of the arrow P until they are in a position in which the bristle bundles 26a, 26b are each driven by a stuffing tool 24a, 24b in a linear movement at the same time into a hole 28a, 28b of one of the bristle carriers 30a, 30b can be introduced.
  • the embodiment in Figure 4 differs from the one in Figure 3 embodiment shown in that the bristle bundles are simultaneously introduced into corresponding holes of a plurality of perforated field patterns which are formed in a perforated field plate.
  • Figure 5 shows a further embodiment in which the bristle bundles 16a, 16b are introduced into a single hole of a hole field pattern.
  • Figure 5 shows a perforated field plate 19 which has a hole 17 with a funnel-shaped opening.
  • the bristle bundles 16a, 16b are, as in the in Figure 1 shown embodiment, separated from the bristle supply 2 and conveyed to the tamping tool 6 by means of the dividing element 4.
  • the bundles of bristles are then simultaneously removed from the compartment element 4 by means of the stuffing tool 6 and are conveyed in a linear movement to the opening of the hole 17.
  • the bristle bundles 16a, 16b are then introduced into the hole 17 at the same time, the bristle bundles 16a, 16b sliding off the funnel-shaped surface of the opening.
  • the distance between the recesses of the dividing element and the distance between the holes to be plugged are preferably coordinated so that the divided bundles of bristles can be introduced into the holes while maintaining their lateral spacing.
  • the split-off bristle bundles can be the bristle bundles, which can be seen as individual bristle bundles on the finished brush, on the other hand, the split-off bristle bundles can form the subset of an enlarged bristle bundle.
