Definitions

  • the present invention relates to a method for producing brushes, in particular toothbrushes, in which the bristle bundles are divided from at least one bristle supply in a first direction of movement by a single compartment element which bears sealingly against an opening of the bristle supply and is fastened to at least one bristle carrier by the latter Abforcelement be removed in a second direction of movement, wherein, after in the first direction of movement a plurality of bristle bundles have been divided with the one Abwellement, the Abforcelement is stopped and these bristle bundles are removed simultaneously in the second direction of movement from the Abforcelement.
  • the present invention is based on the problem to improve the generic method in terms of its speed and performance.
  • a plurality of bristle bundles with a first circular segment-shaped movement can be divided off from a bristle supply and provided at the same time for attachment to at least one bristle carrier.
  • the performance of the method can be improved.
  • inventive Methods for providing bundles of bristles for attachment to the bristle carrier are initially separated from a bristle supply by a compartment element in a first circular segment-shaped movement direction. After the bundles of bristles have been divided by means of the dividing element, the dividing element is stopped and the bundles of bristles held on the dividing element are grasped in a second direction of movement, preferably orthogonal to the first direction of movement, and removed at the same time.
  • the bristle bundles are removed substantially simultaneously, namely that the bundles of bristles initially provided in a first direction of movement are removed from the dividing element before it is set in motion again for dividing further bristle bundles.
  • the bundles of bristles removed in the second direction of movement are finished bundles of bristles, which can be seen as individual bundles on the finished brush or form the subset of an enlarged bundle of bristles in which a plurality of bristle bundles are combined with identical or substantially identical number of bristle filaments.
  • the bristle bundles thus produced are removed from the compartment element for attachment to the bristle carrier. This means that the bristle bundles are removed from the compartment element.
  • the bristle bundles can either be gripped with a stuffing tool in a manner known per se and fastened directly to the bristle carrier.
  • 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 perforated field pattern in the second direction of movement, which corresponds to a bristle arrangement of a single bristle carrier.
  • the perforated field pattern according to 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 bundles of bristles are introduced at the same time in the or the hole field pattern in the second movement, such a perforated field pattern can be stuffed faster with bristle bundles.
  • the bristle bundles are held in the second direction of movement via a common stuffing tool and at the same time introduced into different holes of the at least one hole field pattern.
  • the stuffing tool required to carry out this preferred method of operation can be designed, despite increased output, with only slightly higher mass than a stuffing tool for stuffing only one bristle bundle.
  • the bristle bundles are held in the second direction of movement over a plurality of stuffing tools and at the same time introduced into different holes of the at least one hole field pattern.
  • the different stuffing tools are preferably coordinated so that even in the event of failure of one or more Stopftechnikmaschineen the still working stuffing tools can ensure production.
  • the bristle bundles are simultaneously introduced into corresponding holes of different perforated field patterns in the second direction of movement.
  • This preferred process facilitates mass production of a plurality of identical hole pattern brushes.
  • the relative movement between the hole field pattern and the stuffing tool in a direction substantially transverse to the extension of the holes required to stuff a hole field pattern to provide empty holes for the stuffing device in this embodiment detects a plurality of hole field patterns whose corresponding holes are stuffed with bristle bundles at the same time ,
  • This preferred development of the method according to the invention initially simplifies the structural design of the device required for carrying out the method.
  • the preferred method is particularly suitable for the preparation of bundles of bristles which are stuffed into a perforated field pattern whose holes have identical lateral spacing from each other. The lateral spacing of the recesses provided on the dividing element and accommodating the bristle bundles corresponds exactly to this lateral spacing of individual holes of the perforated field pattern.
  • the prepared bundles of bristles taken from the dividing element at the removal position are directly introduced into adjacent holes of the perforated field pattern in this preferred embodiment without changing their lateral spacing.
  • the movement in the second direction of movement may be an exclusively linear movement, resulting in a fast and simple procedure.
  • the bristle bundles are held in the second direction of movement via a common stuffing tool and at the same time introduced into a single hole of the perforated field pattern.
  • the bundles of bristles are thereby conveyed while maintaining their lateral distance to an opening of a hole and moved toward each other when introduced into the hole.
  • the bristle bundles slide on insertion into the hole on the surface of a funnel-shaped opening of the hole. This ensures a safe introduction of the bristle bundles into the hole with a simple configuration of the device for carrying out the method.
  • FIG. 1 and 2 each schematically show essential parts of a device for carrying out the method, which has a bristle storage container 2, a circular-arc-shaped dividing element 4 and a stuffing tool 6.
  • the compartment element 4 lies with its outer peripheral surface 8 sealingly against an opening of the bristle reservoir 2. Furthermore, the compartment element 4 has two recesses 10a, 10b positioned next to one another.
  • bristle filaments 12 are removed from the storage container 2 by means of the compartment element 4.
  • a certain number of bristle filaments 12 are removed from the bristle storage container 2 only when the recesses 10a, 10b of the compartment element 4 at the opening the bristle reservoir 2 are passed.
  • the bristle filaments 12 are thereby divided into two different bristle bundles 14 in a controlled manner.
  • the bristle bundles 14 are guided in a continuous movement in the direction of the arrow P to a stuffing tool 6.
  • the circular compartment element 4 terminates the first direction of movement only when the bristle bundles 14 have reached a position in which the bristle bundles 14 can be introduced in a linear movement in holes 16 provided for them of a bristle carrier 18 at the same time.
  • this second movement which is substantially orthogonal to the first movement, ie substantially perpendicular to the instantaneous movement of the bristle bundles 14 immediately prior to stopping of the dividing element 4 for removal of the bristle bundles 14, the bristle bundles 14a, 14b are spaced apart so that the distance between the bristle bundles 14a, 14b, 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) corresponds.
  • FIG. 2 is different from the one in FIG. 1 shown embodiment in that the bristle bundles are introduced into a single hole field plate 20. Thereafter, the perforated field plate 20 can either be attached directly to a bristle carrier or serves as a support while the bundles of bristles are attached to a bristle carrier.
  • FIG. 2 - as well as in the FIGS. 4 . 5 -
  • the introduction of the bristle bundles in the hole field plate 20 is shown schematically simplified. In fact, the bundles 14a, 14b are removed from the tamping tool and introduced into the perforated field plate 20 in the axial direction, ie perpendicular to the plane of the drawing.
  • the dividing element 4 abuts on its outer circumferential surface 8 on a counter surface, are closed by the recesses 10a, 10b.
  • the bristle bundles 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 embodiments of the method according to the invention.
  • FIGS. 1 and 2 like parts, marked with the same reference numerals.
  • the in the FIG. 3 shown bristle arrangement has two stuffing tools 22a, 22b.
  • the sealing element abutting against the bristle storage container 2 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.
  • 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 bundles of bristles 26a, 26b are each moved simultaneously by a tamping tool 24a, 24b into a respective hole 28a, 28b of one of the bristle carriers 30a, 30b can be introduced.
  • FIG. 4 is different from the one in FIG. 3 shown embodiment in that the bristle bundles are simultaneously introduced into corresponding holes of a plurality of hole field pattern formed in a perforated field plate.
  • FIG. 5 shows a further embodiment in which the bristle bundles 16a, 16b are introduced into a single hole of a perforated field pattern.
  • FIG. 5 shows a perforated field plate 19 having a hole 17 with a funnel-shaped opening.
  • the bristle bundles 16a, 16b become, as in the in FIG. 1 shown embodiment, separated from the bristle supply 2 and conveyed by the Abteielement 4 to the stuffing tool 6.
  • the bristle bundles are then removed at the same time by means of the stuffing tool 6 of the compartment element 4 and are conveyed in a linear movement to the mouth of the hole 17.
  • the bristle bundles 16a, 16b are then introduced into the hole 17 at the same time, with the bristle bundles 16a, 16b sliding off the funnel-shaped surface of the opening.
  • the distance between the recesses of the compartment element and the distance between the holes to be stuffed is preferably matched to one another such that the divided bristle bundles can be introduced into the holes while maintaining their lateral spacing.
  • the divided bristle bundles the bundles of bristles which can be seen as individual bristle bundles on the finished brush, can be, on the other hand, the divided bristle bundles can form the subset of an enlarged bristle bundle.
