    Brush making machine and method for introducing bristle bundles into openings of a bundle carrier
    The invention relates to a brush making machine and to a method of making brushes.
    Various approaches and methods are known for inserting bristle bundles or tufts into a brush body. In particular, in brushes, in which complex arrangements of bristle bundles are used, for example, toothbrushes with differently aligned bristle bundles and bristle bundles of different bristles, the introduction of the bristle bundles in the corresponding openings is quite expensive.
    The object of the invention is to enable a reliable and yet flexible production of brushes, in particular toothbrushes, at low cost.
    To achieve this object, according to the invention a brush manufacturing machine is provided with a holder for holding a bristle carrier, a bristle reservoir, a bundle taker, which is provided at an outer edge with at least two bundle receiving notches and cooperates with the bristle reservoir, and a mechanical insertion device, the bristle bundles from the bundle receiving notches in a direction that is generally perpendicular to the adjustment of the outer edge of the bundle pickup to move towards the holder. To achieve this object, the invention also provides a method for introducing bundles of bristles into openings of a bundle carrier, in particular by means of a machine of the aforementioned type, the method comprising the following steps: a bundle taker, which is provided with at least two bundle receiving notches, bristles are supplied forming a bundle of bristles. The bundle carrier is suitably positioned relative to the bundle picker. The bristle bundle is mechanically inserted into an opening of the bundle carrier.
    The invention is based on the idea of using the bundle pickup to preform two or more bristle bundles, in particular also with regard to the distance from one another. In this way, a plurality of bristle bundles can be used directly in the bundle carrier.
    According to one embodiment of the invention, a plurality of bundle pickers are provided. As a result, on the one hand, the clock rate can be increased. On the other hand, this makes it possible to equip even very complex opening patterns on the bundle carrier efficiently.
    According to one embodiment of the invention, it is provided that the bundle pickup is a bundle pick-up wheel. This can in particular be further adjusted in a single direction of rotation, so that a plurality of different bundle picking notches can be provided along the circumference of the bundle pickup wheel.
    According to an alternative embodiment of the invention, it is provided that the bundle pickup is a translationally movable bundle pickup slider. This results in a very compact design.
    According to a further alternative it can be provided that the bundle pickup is a reciprocally adjustable bundle pickup rocker. In this embodiment can be used as a bundle buyer in its fundamentals known and thus tested component.
    According to one embodiment of the invention it is provided that a plurality of holders are provided and a holder drive, which can adjust the holder relative to the bundle pickup. The holder drive ensures that the holders are positioned correctly relative to the bundle picker in order to be able to insert a bristle bundle located in the bundle collector into an opening provided for the bristle bundle.
    It is preferably provided that the holder drive is a holder indexing drive, which advances the holders evenly. In this way, there is a low control effort.
    According to a preferred embodiment of the invention it is provided that the holder is adjustably mounted on the holder drive. In this way, the holder can be individually aligned relative to the bundle taker. This can be done by means of a Halterpositionierantriebs, both along the
    Direction in which the holder is adjusted, as well as across it. Furthermore, it is possible to pivot the holder, so that bristle bundles can be mounted in different orientations on the holder.
    It is also possible to individually position the holder relative to the bundle picker in that a bundle picker positioning drive is provided with which the bundle picker is adjusted relative to the holder or to the position of the holder. This has constructive advantages, since the bundle picker positioning drive is basically designed to be fixed, while the Halterpositionierantrieb is provided circumferentially on the holder drive.
    If desired, the bundle positioning drive and the insertion device and other components can be adjusted, which are involved in the insertion of the bundles in the openings of the bundle carrier.
    According to a preferred embodiment of the invention, it is provided that the bundle receiving notches differ from one another with regard to their contour and / or their cross section. As a result, different bristle bundles can already be preformed in the bundle taker.
    It is preferably provided that the bundle pickup is provided at its outer edge with a plurality of groups of bundle receiving notches. As a result, the cycle frequency of the machine can be increased because it is not necessary between the insertion of two bundles of bristles to adjust the bundle pickup to a complete cycle, but only from one group of bundle receiving notches to the next.
    It is preferably provided that the groups of bundle receiving notches differ from one another with respect to the contour of the bundle receiving notches, the cross section of the bundle receiving notches and / or the number of bundle receiving notches within a group. With differing groups of bundle picking notches on the bundle picker, very complex bundle patterns can be created on the brush.
    According to one embodiment of the invention it is provided that the bundle receiving notches at least partially have a non-circular contour. Such a contour makes it possible to preform rectangular, oval, triangular or other bristle bundles already in the bundle picker, which are then introduced into openings in the holder.
    According to a preferred embodiment of the invention, a plurality of bristle reservoirs are provided. As a result, a brush can be equipped with different bristles with little effort. "Different bristles" means that the bristles differ in terms of their material, their color, their diameter and / or other physical properties.
    Preferably, an adjustment for the reservoir is provided, with which the bristle reservoir can be adjusted relative to the bundle customers. The adjustment makes it possible to arrange at the desired time a bristle reservoir, which is equipped with the desired type of bristles, suitably on the bundle pickup.
    According to one embodiment of the invention, a filling station is provided to fill the bristle storage containers with bristles. This allows automated operation of the machine.
    It may further be provided a welding station to weld bristles. The bristles can either be welded to adjacent bristles and / or with the material of a holder so that they are firmly held in the holder.
    There may also be provided a finishing station for cutting, dressing and / or rounding the bristles. It is then no longer necessary to supply the holder with the bristle bundles to a separate machine in which these steps are performed.
    In principle, it is also possible to use bristles which are mechanically or chemically sharpened. Similarly, pre-rounded bristles can be processed. In these cases, rounding at the finishing station is eliminated.
    According to a preferred embodiment of the invention, an insertion aid is provided with at least one bundle guide opening between the bundle picker and the holder. The insertion aid makes it easier to insert the bristle bundles from the bundle receiving notch into the opening of the holder.
    The insertion aid can be used to "translate" the bundles as they are inserted to compensate for an offset between the position of the bundle in the bundle pickup and the position of the opening in the bundle holder. For this purpose, for example, a bundle guide opening can be used, which extends obliquely through the insertion.
    The bundle picker facing side of the bundle guide opening is adapted to the contour and the cross section of the corresponding bundle receiving notch with respect to their contour and their cross-section. This ensures that the bristle bundle can be inserted from the bundle receiving notch into the bundle guide opening. The insertion of the bristle bundles can be assisted by the fact that an insertion bevel is provided.
    According to one embodiment of the invention, it can be provided that the side of the bundle guide opening facing away from the bundle pickup has a contour which deviates from the contour on the bundle pickup side of the bundle guide opening. In this embodiment, the insertion aid is used to transform a bundle of bristles held in a bundle receiving notch, which there has a cross section predetermined by the contour of the bundle receiving notch, into a bristle bundle having a different contour.
    According to one embodiment of the invention, it can also be provided that the bundle guide opening extends, at least on the side remote from the bundle pickup, in a direction which deviates from the direction in which the bundle of bristles held in the bundle receiving notch extends. This embodiment is particularly advantageous when the opening to be filled in the holder is oriented obliquely to the direction in which the bristle bundle is held in the bundle receiving notch. It is then not necessary to position the holder suitably obliquely, so that the bristle bundle can be inserted, but the necessary deflection can be done directly by means of the bundle guide opening of the insertion.
    It can also be provided that the insertion aid has two or more separate bundle guide openings on the side facing the bundle pickup which are brought together in a single bundle guide opening on the side facing away from the bundle pickup. In this embodiment, the insertion can be used to two
    Bundle bristle bundles with preferably different bristles to form a single bundle of bristles, which is then introduced into an associated opening in the holder.
    The introducer can also have a large bundle guide opening in which several bundles are brought together, which are then inserted into a common opening in the bundle carrier.
    According to one embodiment it is provided that the holder is sequentially equipped with different bristle bundles, wherein the holder is repositioned between the individual loading operations. This ensures that the holder is optimally aligned for the bristle bundles to be introduced.
    According to one embodiment it is provided that the holders are adjusted together relative to the bundle pickups, wherein the distance between the individual bundle pickup from one another differs slightly from the way by which the holders are moved further at each step. In this embodiment, there is a low cost for the Weiterverstellen (indexing) of the holder, since they are all weiterverstellt the same way. This can be achieved, for example, by connecting the holders to one another. In this embodiment, the openings arranged at different positions of the bundle carrier are "approached" in that the individual bundle pickers are positioned differently from the predetermined position of the bundle carrier that the bundle carrier has in each case when it is positioned on the respective bundle taker by means of the holder.
    The bundle pickups can be arranged on a bundle picker positioning drive with which the bundle pickers (and, if necessary, other components such as the insertion device and also the insertion aid) can be aligned to the desired position.
    According to an alternative embodiment, it is provided that the holders are adjusted together by means of the holder drive, but additionally individually individually positioned relative to the corresponding bundle pickup, for example by means of a Halterpositionierantriebs. In this embodiment, each bundle carrier is positioned on the corresponding bundle picker so that the opening to be populated is suitably aligned relative to the bristle bundle located in the corresponding bundle receiving notch.
    According to a preferred embodiment, it is provided that at least two bundle pickups are provided, each having at least two bundle receiving notches, wherein the bristle bundles located in the first bundle receiving notch of the first and second bundle pickers are simultaneously inserted into an associated opening of the bundle carrier, whereupon the bundle pickers are so be further adjusted that the bundle carrier is assigned a second bundle receiving notch of the first and the second bundle pickup, wherein the bristle bundles of the second bundle receiving notches are inserted simultaneously into the next opening of the bundle carrier. The term "simultaneously" does not mean that the insertion of the two bundles of bristles exactly at the same time (in the same sense
    Fractions of seconds), but within the same cycle or step, ie between the further adjustment of the bundle takers from one to the next position.
    The invention will be described below with reference to various embodiments, which are illustrated in the accompanying drawings. In the drawings: FIG. 1 schematically shows two adjacent bundle receivers and
    Bristle reservoir of a brush making machine; - Figure 2 on an enlarged scale one of the two bundle pickup of Figure 1; Figure 3 shows schematically an embodiment of a brush making machine using four bundle pickers in the form of bundle picking wheels; Figures 4a to 4d show four bundle picking wheels of the machine of Figure 3 cooperating with a bristle storage bin and a bundle carrier; - Figure 5 shows an alternative embodiment of the bundle pick-up wheel; FIGS. 6a to 6d show four bundle pickups designed as bundle picking wheels of an alternative to the embodiment shown in FIGS. 4a to 4d; FIG. 7 shows schematically another embodiment of a brush making machine; Figures 8a to 8j show the ten bundle picking wheels used in the brush making machine of Figure 7; FIGS. 9a to 9c show a brush manufacturing machine according to a further embodiment in various states when a bristle carrier is loaded; FIGS. 10a to 10c show a further variant of the brush-making machine of FIG. 9, and FIG. 11 shows a schematic view of a brush-making machine according to a further embodiment.
    Figures 1 and 2 show some of the basic components of a brush making machine according to the invention. These elements are for each insertion station a bundle pickup 10, which is designed here as a bundle pick-up, a bristle storage container 20, a slide-in device 40 and a holder 50 for holding a bundle carrier 5, which is to be provided with bristle bundles. Furthermore, an insertion aid 30 is shown.
    The bundle carrier 5 contains a plurality of openings 6, which are to be equipped with bristle bundles.
    When a toothbrush is to be manufactured with the brush making machine, the bundle carrier 5 may be the head portion of a toothbrush body into which the bundles of bristles are directly inserted.
    The bundle carrier 5 may also be a small carrier plate, the openings 6 are provided with the bristle bundles. It is then possible to attach the bristle bundles to the bundle carrier, for example by welding or gluing, and then the bundle carrier to a
    To attach toothbrush body or overmold with plastic so that it is part of the toothbrush body.
    The bundle carrier 5 can also be equipped with additional elements, for example rubber elements or soft plastic elements.
    The bundle carrier 5 can also be an intermediate carrier, e.g. be made of metal, which holds the bristle bundles until further processing, for example, until they are molded directly with the toothbrush body forming material, whereby they are fixed there.
    Generally speaking, the bundle carrier 5 is an arbitrary component provided with openings into which a plurality of bristle bundles are to be inserted. The bundle carrier 5 can then later be part of the brush to be produced or else only temporarily hold the bundles of bristles until they are connected to the brush to be produced.
    The openings 6 in the bundle carrier 5 may have different and different contours. In principle, all openings 6 may have a circular contour with the same diameter. However, the brush production machine makes it possible to equip even more complex opening pattern (see in particular Figure 2). As examples, two elongate openings of different sizes and two circular openings of different sizes or cross sections are shown here. Each of the openings 6 is intended to receive a bristle bundle 14, the cross section of the bristle bundle corresponding to the cross section or the contour of the corresponding opening 6.
    In the embodiment shown, the bundle picker 10 is designed as a bundle pickup wheel or disc. The bundle pickup wheel 10 is mounted so that it can be rotated about its central axis. For this purpose, a (not shown in the drawings) drive is provided. The drive may, for example, be a servo drive with which the bundle pickup wheel 10 can be precisely adjusted in a controlled manner by a desired angle of rotation.
    The bundle pickup wheel 10 is adjusted in particular in a single direction (see, for example, the arrow in Figure 2).
    Each bundle picking wheel 10 is provided with at least two bundle receiving notches 12 (only a single bundle picking notch 12 is shown in Figures 1 and 2 for simplicity).
    Each bundle receiving notch 12 is disposed on the outer circumference of the bundle pickup wheel 10 so as to be opened to the outer circumference of the bundle pickup wheel 10. In other words, each bundle receiving notch 12 represents an interruption of the circular periphery of the bundle pickup wheel 10. Referring to the geometric shape of the bundle receiving notches 12, it is always assumed that the radially outward side of the contour is a virtual continuation of the circumference of the bundle pickup wheel 10 is formed.
    Each bundle receiving notch 12 is designed with a special contour corresponding to the contour of a particular one of the openings 6 in the bundle carrier 5.
    In FIG. 2, it can be seen that the bundle receiving notch 12 has a triangular cross section, with one of the tips of the triangle being directed towards the center of the bundle pickup wheel 10. This contour coincides with the contour of a triangular opening 6 provided in the bundle carrier 5. This special opening 6 is designated in FIG. 1 by the reference numeral 6T.
    The bristle reservoir 20 is configured to receive a very large number of individual bristles 22 held here between guides 24, shown schematically. In addition to the guides 24 shown in FIGS. 1 and 2, at least one bottom plate is additionally provided.
    The bristle storage container 20 is arranged so that the bristles contained therein are offered to the outer periphery of the bundle pick-up wheel 10. In particular, the bristles 22 are pressed lightly against the bundle pickup wheel 10.
    The bundle pickup wheel 10 is rotated relative to the bristle storage container 20 so that the bundle receiving notch 12 is guided past the bristles provided in the bristle storage container 20. As the bristles are slightly biased against the buncher wheel 10, a certain amount of bristles 22 enter the bundle receiving groove 12 until it is completely filled and forms a bundle of bristles. When the bundle pickup wheel 10 is further indexed, the bristles 22 contained in the bundle receiving notch 12 are transported in the form of a bundle of bristles 14 to an insertion position shown in Figures 1 and 2 and in which the bristle bundle 14 is inserted into the bundle carrier 5, in particular in an opening 6 to be equipped.
    Along the outer circumference of the bundle pickup wheel 10 is provided an additional guide (not shown) for preventing the bundles of bristles from leaving the bundle receiving notches 12 as they are moved from the pickup position on the bristle hopper 20 to the insertion position below the insertion device 40.
    In order to insert the bristle bundle 14 into the corresponding opening 6 of the bundle carrier 5, the insertion device 40 is provided, which exerts a pushing or pushing force on the bristle bundles in such a way that they are pushed in towards the bundle carrier 5 and into the corresponding opening 6. With reference to Figures 1 and 2, the inserter 40 pushes the bristle bundle 14 downwardly, as symbolized by the arrow.
    The bristles are inserted into the bundle carrier 5 at such a speed that they do not dodge laterally, but are inserted in a straight line along their longitudinal axis into the corresponding opening 6.
    The insertion device 40 may be designed as a punch or piston, which simultaneously inserts a bristle bundle or a plurality of juxtaposed bristle bundles from the bundle pickup 10 through the insertion aid 30 into the bundle carrier 5.
    In order to ensure that the bristle bundle enters correctly into the corresponding opening 6 of the bundle carrier 5, the insertion aid 30 is arranged between the "front" end of the bristle bundle 14 and the opposite side of the bundle carrier 5. In this case, the insertion aid 30 is designed as a plate provided with insertion holes 32. These have a contour corresponding to the contour of the bundle receiving notch 12, the bundle of bristles 14 contained therein, and the corresponding opening 6 into which the bundle of bristles is to be inserted.
    In FIG. 2, for example, the insertion aid 30 has a triangular insertion opening 32 for the triangular bundle of bristles 14, that of the one in FIG. 1 on the left
    4 and a circular insertion opening 32 for the circular bundle of bristles 14 provided by the bundle pickup wheel 10 shown in FIG. 1 on the right side. Each of the insertion openings 32 is provided on the bundle picking wheel side facing with a chamfer 34, so that the insertion of the bristle bundles 14 is facilitated. During operation, a bundle carrier 5 is positioned by means of the holder 50 suitably below the bundle pickup wheel 10. For this purpose, a holder drive, a holder positioning drive and / or a Bündelabnehmerpositionierantrieb can be used, which will be explained later.
    When a bundle of bristles 14 has been transported from the bristle storage container 20 to the insertion position above the bundle carrier 5, the insertion device 40 pushes the bristle bundle 14 first through the insertion opening 32 of the insertion aid 30 and then into the corresponding opening 6 of the bundle carrier 5. FIG. 2 shows a bundle carrier 5 which is already provided with a bristle bundle 14 with a circular cross section and which is next provided with a bristle bundle 14 with a triangular cross section. During insertion, each bristle bundle is pushed completely through the insertion aid 30, so that the end of the bristle bundle 14, on which the insertion device 40 engages, is in the broadest sense flush with the side of the bundle carrier 5 facing the bundle pickup wheel 10.
    Notwithstanding "straight" insertion openings 32 and insertion can be used, which are used for forming and / or deflecting the inserted into them bristle bundles. Thus, for example, a bristle bundle can be deflected during insertion from a vertical extension direction in an obliquely extending direction, so that it can be inserted optimally in an obliquely to the vertical direction opening 6 in the bristle carrier 5. It is alternatively or additionally possible that the bundle of bristles of a first cross-sectional shape, which is predetermined by the contour of the bundle receiving notch 12 in the bundle pickup 10, is formed into a second cross-sectional shape, for example from round to square. Furthermore, it is alternatively or additionally possible for two or more insertion openings 32 starting separately on the "top side" of the insertion aid 30 to meet in the further course so that two or more bundles of bristles held in separate bundle receiving notches 12 on the bundle picker become a single one Bundles are combined, which is then inserted into the opening of the bundle carrier 5.
    The insertion apertures may also be used to laterally displace the bristle bundles to compensate for an offset between the position of the bundle in the bundle receiving notch and the position of the opening in the bundle carrier.
    FIG. 3 shows an embodiment of the brush manufacturing machine in which four different bundle pickup wheels 10 are shown, wherein each bundle pickup wheel first forms a plurality of bristle bundles with different contours and then transports these from the pickup position to an inserted position. During operation, the bundle picking wheels 10 are each adjusted in a single direction (counterclockwise in the figures).
    The brush manufacturing machine shown in FIG. 3 uses a plurality of bristle storage containers 20 attached to a bristle container adjustment drive 26. The bristle container adjustment drive 26 is here similar to a carousel, which adjusts bristle storage containers 20 along the bundle picking wheels 10 and also along a filling station 28, at which each of the bristle storage containers 20 is supplied with new bristles 22. To transport the reservoir, a servo drive can be used.
    The holders 50 are turned on a holder drive 52, which is also carried out here in the manner of a carousel. The holder drive 52 may in particular be a holder indexing drive with which the holders 50 (and thus the bundle carriers 5 arranged thereon) are successively adjusted by steps of the same size along the individual bundle picking wheels 10.
    As can be seen by comparing the position of the bundle beams 5 with respect to the outer circumference of the first, second, third and fourth bundle pickup wheels 10, the bundle beams 5 are presented to the bundle pickup wheels 10 in different positions.
    The bundle carrier 5 is presented to the first bundle pickup wheel 10 so that the outer circumference of the first bundle pickup wheel 10 "cooperates" with the outermost right edge of the bundle carrier. In other words, the right outer edge is presented to the bundle receiving notches 12 of the bundle pickup wheel 10.
    The outer periphery of the second bundle pickup wheel 10 cooperates with the right middle portion of the bundle carrier 5.
    The outer periphery of the third bundle pickup wheel 10 cooperates with the left middle portion of the bundle carrier 5.
    The outer circumference of the fourth bundle pickup wheel 10 finally interacts with the outer left edge of the bundle carrier 5.
    The different positions of the bundle carrier 5 on the respective bundle picking wheels 10 are achieved by a holder positioning drive 54, which is shown schematically in detail 3 of FIG. The holder positioning drive 54 is operative between the holder drive 52 and the holder 50 and is adapted to slightly move the holder 50 forward and backward (see arrow P) with respect to the direction in which the holders 50 are displaced by the holder drive 52. In addition, the holder positioning drive 54 may be configured to slightly rotate the holders 50 so that the bundle carrier 5 may be presented to the corresponding bundle pickup wheel 10 at different angles (see arrow R). It may moreover be provided that the holder positioning drive 54 adjusts the holders transversely to the adjustment direction of the holder drive 52.
    As an alternative to a holder positioning drive, a bundle picker positioning drive can also be used with which the position of the bundle picker relative to the holder drive can be adjusted. The bundle picking positioning drive can be designed, for example, as a sliding guide or carriage, with which the bundle picker can be suitably positioned along the adjustment direction of the holder. At the Bündelabnehmerpositionierantrieb also the insertion device and the insertion can be mounted so that they are synchronized with the bundle pickup.
    FIG. 4 a shows in detail the various bundle receiving notches 12 which are arranged on the outer circumference of the first bundle pickup wheel 10. It can be seen that a group of bundle receiving openings 12 is provided which have different shapes, for example a circular contour, a parallelogram-like contour, a triangular contour and a rectangular contour. These bundle receiving notches 12 form bundles of bristles 14 which have the same cross-section or contour as the corresponding bundle receiving notch 12 and which are then transported so that they are presented in the insertion position to the corresponding bundle carrier 5. There they are inserted into the corresponding opening 6.
    In FIG. 4 a, it can be seen that the openings 6 in the bundle carrier 5 are not aligned exactly with the bundle receiving notches 12 on the outer circumference of the bundle pickup wheel 10. However, this is not a problem because the insertion aid 30 is used to suitably guide the bundles of bristles 14 into the associated openings 6 while also compensating for a certain offset.
    The insertion aid 30 is not shown in Figure 4 in order not to adjust the view of the bundle carrier 5.
    In Figure 4b, the second bundle pickup wheel 10 is shown, which is provided at its outer periphery with a group of bundle receiving notches 12, all of which have a circular cross section or a circular contour here, but with different diameters. These bundle receiving notches 12 serve to provide six openings 6 in the bundle carrier 5 with six bristle bundles 14. Again, it can be seen that the position of the bundle receiving notches 12 need not necessarily coincide exactly with the position of the openings 6 in the bundle carrier 5.
    In Fig. 4c, the bundle picking wheel 10 is provided with another group of bundle receiving notches 12, namely two bundle receiving notches having a circular contour and a slot-like bundle receiving notch 12 disposed therebetween. It can be seen that the bundles of bristles 14 held in these bundle receiving notches 12 are in the insertion position in FIG associated openings 6 are inserted in the bundle carrier 5, which openings are again not perfectly aligned with the bundle receiving notches 12 of the Bündelabnehmerrades 10.
    In FIG. 4d, the final step of inserting bundles of bristles 14 into the remaining openings of the bundle carrier 5 is shown, wherein the bundle receiving notches 12 arranged on the outer circumference of the fourth bundle pickup wheel 10 have a contour that is mirror-image to the bundle receiving notches 12 arranged on the outer circumference of the first bundle pickup wheel 10 ,
    In FIG. 4d, it can be seen that the offset between the two outer, parallelogram-like bundle receiving notches 12 relative to the associated openings 6 in the bundle carrier 5 is not insignificant. Nevertheless, the insertion aid 30 makes it possible to insert the bristle bundles into the associated openings 6 of the bundle carrier 5 in a suitable manner.
    When all the openings 6 in the bundle carrier 5 are provided with their bristle bundles 14, the holder indexing drive 52 transports the bundle carriers 5 to a schematically shown finishing station 60, in which the
    Bristle bundles are finished. The finishing may be to trim and / or align the bristles to the desired length. Furthermore, the bristles can be rounded at their free ends.
    If pre-rounded bristles are used, the cost of rounding can be reduced or rounding off can be completely eliminated.
    It can also be provided that a certain contouring or profiling of the entirety of the bundles is achieved by axially displacing the bristles relative to the bundle carrier.
    After the bristles are finished in the finishing station 60, the holder indexing drive 52 transports the bundle carriers 5 to a welding station 62 where the ends of the bristles received in the bundle carrier are heated so that the material of the bristles is slightly melted. It is also possible that the material of which the bundle carrier 5 is made, is slightly melted. Here, the bristles materially connect to each other and optionally with the bundle carrier 5 similar to a welding.
    In principle, it is possible to interchange the order of the finishing station 60 and the welding station 62, so that first the
    Bristles firmly together and optionally connected to the bundle carrier 5 and then finished.
    FIG. 5 shows an alternative embodiment of the bundle pickup wheel 10. The bundle pickup wheel 10 is here provided on its outer circumference with four groups of bundle receiving notches 12, each group corresponding to a group of bundle picking notches provided on the four bundle picking wheels 10 of Figures 4a to 4d. During operation, each bundle pickup wheel 10 is indexed in increments of 90 °. Each of these positions corresponds to an insertion position of the bundles of bristles 14 arranged in the corresponding group of bundle receiving notches 12 and the receiving position for the subsequent group of bundle receiving notches 12.
    In principle, the groups of bundle receiving notches 12 can also be distributed unevenly around the circumference of the bundle pickup wheel 10, in which case the bundle pickup wheel 10 is moved further between each cycle by a suitable angle, but then deviating from 90.degree.
    With the bundle pickup wheel 10 shown in FIG. 5, the bundle carriers 5 need not be further shifted between the different bundle pickup wheels 10 to be provided with the bristles as in the embodiment of FIGS. 3 and 4. Instead, it is only necessary to slightly adjust the holder 50 relative to the buncher wheel 10 to better align the openings 6 to be provided with the next set of bristle bunches 14 with the associated bundle receiving notches 12 of the next group of bundle picking notches. This adjustment can be done by means of the holder drive 52 or the Halterpositionierantriebs 54.
    When all the openings 6 are filled, the holder 50 is further moved to present the bundle pickup 10 to the next bundle carrier 5.
    In Figures 6a to 6d, an alternative embodiment of the brush manufacturing machine is shown. The difference from the first embodiment is that the bundle carrier 5 is provided with bundles of bristles 14 which differ from each other, not only in terms of their contour.
    Each of the four bundle picking wheels 10 is associated with a bristle storage bin 20 containing different types or types of bristles 22a through 22d. The difference between the bristles may be color, material, diameter or other properties.
    The first bundle pickup wheel 10 shown in FIG. 6a is intended to supply a total of four bristle bundles 14 to the bundle carrier 5, the holder 50 being displaced in the direction of the arrow A to allow the first bundle pickup wheel 10 to connect the two groups of bristle bundles 14 suitable for the associated openings 6 can provide.
    The second bundle pickup wheel 10 shown in Figure 6b is intended to provide three sets of bristle bundles 14, namely two bristle bundles on each side portion of the bundle carrier 5 and two bristle bundles arranged on the center line. Again, the holder 50 is repositioned between each insertion step by means of the holder positioning drive.
    The third bundle pickup wheel 10 shown in Figure 6c is intended to provide three groups of bristle bundles. Accordingly, three groups of bundle picking notches 12 are provided on the outer circumference of the bundle pickup wheel 10.
    The fourth bundle pick-up wheel 10 (see Figure 6d), similar to the first bundle pick-up wheel shown in Figure 6a, is provided with two groups of bundle receiving notches 12 to provide two groups of bristle bundles 14 for insertion to the respective openings 6 of the bundle carrier 5.
    Obviously, since all holders 50 are indexed or indexed at the same time, the second and third bundle pick-up wheels 10 must be indexed three times for one cycle while the first and fourth bundle pick-up wheels 10 only need to be re-adjusted twice within the same cycle. This can be realized by either selecting a higher operating speed for the second and third bundle pickup wheels 10, or implementing a short pause after the second handoff for the first and fourth bundle pickup wheels 10, while the third picking operation for the second and third bundle pickup wheels 10 is executed.
    FIG. 7 shows a third embodiment of the brush manufacturing machine. For the components known from the preceding embodiments, the same reference numerals are used, and reference is made to the above explanations.
    The difference between the embodiment shown in FIG. 7 and the previous embodiments is that in the third embodiment, a very large number of bundle pickup wheels 10 are used. Here are ten Bündelabnehmerräder 10 are provided.
    As can be seen in FIG. 7, the bundle picking wheels 10 are arranged so that the position of the bundle carrier 5 is different with respect to the outer circumference of the individual bundle picking wheels, respectively. In the case of the first bundle pickup wheel 10, the bundle carrier 5 is arranged such that its right outer edge lies on the outer circumference of the bundle pickup wheel 10.
    As viewed along the different bundle pickup wheels 10, the outer circumference of the corresponding bundle pickup wheel 10 "moves" radially leftward until finally the outer circumference of the tenth bundle pickup wheel 10 lies on the left outer edge of the bundle carrier 5.
    Due to the large number of bundle picking wheels 10, it is possible to insert a bundle of bristles 14 into an opening arranged at an arbitrary position of the bundle carrier 5, without the need for a holder positioning drive 54. In other words, it is "waited" when loading bristle bundles until the corresponding opening has arrived at the Bündelabnehmerrad where it can be equipped with a bristle bundle.
    Another difference between the third embodiment shown in FIG. 7 and the preceding embodiments is that a great many different bristle storage containers 20 (ie storage containers 20 which are equipped with different types of bristles 22) are arranged on the bristle container adjustment drive 26. These are provided at a filling station 28 with new bristles.
    The order of the various bristle storage containers 20a-20d and the sequence in which the various groups of bundle receiving notches 12 are disposed on the outer circumference of the various bundle picking wheels 10 are coordinated so that all the openings 6 of the bundle carriers 5 are provided with the desired type of bristle bundles 14 can. This will be explained in detail below with reference to Figures 8a to 8j for an example of a brush to be provided with four different types of bristles arranged in differently shaped bristle bundles.
    The first bundle pickup wheel 10 shown in Fig. 8a is not provided with any bundle receiving notch 12, since none of the openings 6 of the bundle carrier 5 is in a position particularly suited to be loaded with the first bundle pickup wheel 10.
    The second bundle pickup wheel 10 (see Figure 8b) is provided with four groups of bundle receiving notches 12, here identified by reference numerals 12A to 12D. The bundle receiving notches 12A to 12D are intended to receive bristle bundles 14A to 14D from the corresponding one of the bristle storage containers 20A to 20D.
    The second bundle pickup wheel 10 is here provided with two bundle receiving notches 12A with a parallelogram-like contour, with which two bristle bundles are formed, which consist of a first bristle type 22A. Furthermore, two bundle receiving notches 12B are provided, which have a triangular contour and present to the bundle carrier 5 two bristle bundles 14, which consist of a second type of bristles 22B.
    Further, the second bundle pickup wheel 10 is provided with two bundle receiving notches 12C having a circular contour and presenting to the bundle carrier 5 two bristle bundles 14 of a third bristle type 22C. These are the bristle bundles, which are presented in FIG. 8b to the bundle carrier 5. Finally, the second bundle pickup wheel 10 is provided with two bundle receiving notches 12D having a generally rectangular contour and providing two bristle bundles consisting of a third bristle type 22d.
    A complete cycle of operation is to advance the second bundle pickup wheel 10 four times while also advancing the bristle storage containers 20 four times so that the bundle pickup wheel 10 is able to pick up four different sets of bristle bundles 14A-14D and present them to the bundle carrier 5 in the next step. so that they are inserted into the appropriate opening 6.
    The third bundle pickup wheel 10 (see Figure 8c) is provided with a single group of bundle receiving notches 12B which serve to present to the corresponding openings 6 in the bundle carrier 5 two bristle bundles consisting of the second bristle type 22B.
    The fourth buncher wheel 10 (see Figure 8d) is provided with two sets of bundle receiving notches, a first set of smaller, approximately circular bundle receiving notches 12C and a second set of larger, approximately circular bundle receiving notches 12D. During operation of the brush making machine, they cooperate with reservoirs containing the appropriate type of bristles so that two groups of openings 6 having a circular contour but different diameters are provided with bundles of bristles 14C, 14D.
    The fifth bundle pickup wheel 10 (see Figure 8e) is provided with a single bundle receiving notch 12C having an elongate contour and providing the bundle carrier 5 with a bristle bundle 14C having an elongate contour.
    The sixth bundle pickup wheel 10 (see FIG. 8f) is provided at its outer circumference with two smaller bundle receiving notches 12C forming two bristle bundles 14C which are intended to be inserted into corresponding openings 6 on the bundle carrier 5.
    The seventh bundle pickup wheel 10 (see FIG. 8g) is provided on its outer circumference with two parallelogram bundle receiving notches 12A. These serve to supply two bristle bundles 14A to the corresponding openings 6 in the bundle carrier 5.
    The eighth bundle pickup wheel 10 is provided with two sets of bundle receiving notches, namely, two triangular bundle receiving notches 12B and two rectangular bundle picking notches 12D. These provide the bundle carrier 5 with two sets of bristle bundles consisting of different bristles, namely two bristle bundles 14B made of the second bristle type 22B and two bristle bundles 14D made of the fourth bristle type 22D.
    The ninth and the tenth bundle pickup 10 are provided on its outer circumference with no bundle receiving notch, since all the openings 6 of the bundle carrier 5 were already equipped with bristle bundles with the eighth bundle pick-up 10.
    Also in the third embodiment, the bundle carriers 5, after being loaded with bundles of bristles, can be fed to a finishing station and a welding station. However, these stations are not shown in FIG.
    It can be seen that the brush making machine is very flexible, since many different locations of a bundle carrier 5 can be fed many different types of bristle bundles. If desired, a smaller or a larger number of different types of bristles may be used than shown in the embodiments. It is also possible to provide a larger number of groups of bundle picking notches 12 on the outer circumference of a bundle pickup wheel 10. If desired, the bundle picking wheels 10 may also have different diameters so that the bundles of bristles may be fed to a particular location of the bundle carrier.
    It is also possible to use a holder positioning drive 54 also in the brush manufacturing machine according to the third embodiment. With the holder positioning drive, in particular, the bundle carriers 5 can be slightly pivoted relative to the bundle picking wheels 10 if bristle bundles are to be inserted there at an angle so that they should extend at an angle other than 90 ° with respect to a plane defined by the bundle carrier 5.
    FIGS. 9a to 9c show a brush manufacturing machine according to a further embodiment. For those of the previous ones
    Embodiments of known components, the same reference numerals are used, and reference is made in this regard to the above explanations.
    The essential difference between the brush manufacturing machine according to FIG. 9 and the preceding embodiments is that the bundle pick-up is not designed as a wheel but as a slide.
    The bundle pickup slide 10 is translationally displaceable, thus performs a reciprocating movement in the direction of the arrow P of Figure 9a. On one of the longitudinal edges of the bundle pickup slide 10 a plurality of bundle receiving notches 12 are provided (see Figure 9c), which are equipped with bristles from a bristle reservoir 20.
    In a first step of a complete cycle, the bundle picker 10 is arranged so that the bundle receiving notches 12 face the bristle reservoir 20 (see Figure 9a). A part of the bristles from the bristle storage container 20 enters the bundle receiving notches 12 so that bristle bundles 14 having a cross section corresponding to the contour of the bundle receiving notches 12 are respectively formed there. In the embodiment shown, the bundle receiving notches 12 have a circular, an elongated, a triangular and again a circular cross-section.
    In a second step, the bundle pickup slider 10 is translationally adjusted so that the bristle bundles 14 held in the bundle receiving notches 12 are suitably positioned relative to the bundle carrier 5 (see FIG. 9b).
    Also in the second embodiment, the insertion aid 30 can be used, which is not shown here for the sake of clarity.
    In a third step, the bristle bundles 14 are inserted through the insertion device 40 from the bundle receiving notches 12 and into the openings of the bundle carrier 5 (see FIG. 9 c).
    In another step, not shown in the drawings, the bundle picker 10 then returns to the initial state shown in Figure 9a, where it is refilled with bristles. In this step, not shown, the bundle carrier 5 is also suitably weiterverstellt so that the bundle pickup 10, a new bundle carrier 5 is presented.
    FIGS. 10a to 10c show a variant of the brush-making machine known from FIG.
    Also in the embodiment according to FIG. 10, a bundle pickup slide 10 is used. However, unlike the embodiment of FIG. 9, the bundle picker 10 has not only a single group of bundle receiving notches 12, but two groups of bundle picking notches.
    In Fig. 10a, the bundle picker 10 is in an initial state in which the bundle receiving notches 12A are filled with bristles from a bristle reservoir 20A.
    In FIG. 10b, the bundle picking pusher 10 is adjusted so that the bristle bundles 14A held in the bundle receiving notches 12A of the first group are presented to the bundle carrier 5 so that they can be conveyed by means of the
    Insertion device 40 can be inserted into the openings of the bundle carrier. At the same time, a second group of bundle receiving notches 12B is opposite a second bristle hopper 20B in which another type of bristles 22 are received. The second bristle reservoir 20B has been exchanged for the bristle reservoir 20A during the adjustment of the bundle shuttle 10 from the position shown in FIG. 10a to the position shown in FIG. 10b, for example by means of the adjustment drive 26.
    When the bundle receiving notches 12B are filled, the bundle picking pusher 10 is shifted so that the bristle bundles 14B contained therein are presented to the bundle carrier 5, which is simultaneously adjusted appropriately by the holder positioning drive. The bristle bundles 14B can then be inserted by means of the insertion device 40.
    At the same time (or at the latest when resetting the bundle pickup 10 in the position shown in Figure 10a), the bristle reservoirs 20A, 20B are again suitably implemented, as symbolized by the arrow T in Figure 10c.
    FIG. 11 shows a further embodiment. For the components known from the preceding embodiments, the same reference numerals are used, and reference is made to the above explanations in this respect.
    The essential difference between the embodiment according to FIG. 11 and the preceding embodiments is that, in FIG. 11, the bundle picker is designed as a bundle pickup rocker 10 which can be adjusted about a pivot axis D in a reciprocating movement.
    The operating principle is similar to the embodiment shown in FIG. Two different bristle storage containers 20A, 20B are provided, from which different groups of bundle receiving notches 12A, 12B can each remove bristles. These are then fed to a bundle carrier 5, with suitable further pivoting of the bundle pickup rocker 10, into which they can be inserted.
