    The invention relates to a device and a method for producing brushes or brushes with tufts of fused bristles at one end of the side. fixation.
    In the manufacture of brushes or brushes in which the tufts of bristles are to be melted at one end of the attachment side, the ends of the attachment side are generally subjected to the effect of a hot plate to bring the material of hair to melt. When removing the heating plate, however, molten bristle material may adhere to the heating plate, which may lead to undesirable deformations on the brush or brush article. From EP 2 078 472 B1 a device is known in which the tufts of bristles are subjected, after having been melted with a heating punch, to the effect of another punch to flatten the molten spots until cooling and avoid adhesions to the punch. However, this is complex and therefore expensive.
    If the tufts of bristles are to be connected to another part by melting them, a bead of molten synthetic material widens laterally in the connection region by pressing the tufts heated and melted against the workpiece, which is little attractive and often undesirable on the finished product.
    In addition, there is often, because of the melting of the hair material by means of a metal plate, an unpleasant and possibly harmful plastic odor.
    The problem therefore consists in providing a device of the type mentioned at the beginning with which adhesions and / or beads are avoided and which is easy to achieve from the design point of view.
    The solution according to the invention consists in that there is provided a receiving sleeve of quartz glass, glass-ceramic and / or an alloy thereof to receive at least in places by complementarity of shape, on the one hand , a tuft of bristles and, secondly, a functional portion disposed in the longitudinal direction of the bristles, behind their end of the attachment side, in that there are provided impact elements for exerting an action on the ends free from the tuft of bristles and the functional part and to force the tuft of bristles and / or the functional part in the longitudinal direction of the bristles and in that a heating device disposed outside the receiving sleeve for heating the ends of the tuft of bristles and the functional portion facing each other and for melting the tuft of bristles and a cooling device disposed outside the Receiving nchon to cool the tuft of previously melted hairs.
    Due to the heat input through the receiving sleeve, the tufts of bristles arranged therein are melted and due to the simultaneous compression of the tufts of bristles and the functional part against each other, these two parts are connected to each other. Due to the provision of at least the ends of the tuft of bristles and the functional part to be connected to each other within the receiving socket, the molten plastic material can not extend beyond beyond the inner contour of the receiving sleeve which corresponds to the outer contour of the tuft of bristles so that the formation of a bead is avoided with certainty. Due to the subsequent cooling of the receiving sleeve and the tuft of bristles therein, the plastic is again cooled until it is hardened. The use of quartz glass, glass ceramic and / or an alloy thereof for the receiving sleeve results in good heat permeability so that the heat energy transmission of the heating of a On the other hand, as cooling by the cooling device can take place to a large extent without loss in the inner cavity of the receiving sleeve on the tuft of hair that is there and on the functional part.
    Quartz glass also has a high chemical resistance. It is furthermore advantageous that the receiving sleeve made of the mentioned material has a smooth pore-free surface to which molten plastic material can not remain stuck. Depending on the nature of the material of the receiving sleeve, it has a neutral or even negative expansion coefficient so that the plastic is even detached in addition to the receiving sleeve during the cooling phase. A simple release of the tuft of bristles with the functional part fixed thereto is thus ensured.
    Heating the plastic through the receiving sleeve consisting of quartz glass, glass ceramic and / or an alloy thereof avoids the release of unpleasant plastic odors during melting.
    The functional part may consist in particular of plastic, wood or metal. When plastic is used, it can also melt together with the tufts of bristles as they are heated so that a particularly good bond results between the functional part and the tuft of bristles.
    The functional part can be a rod, a drill bit, a pressure spring or a screw. A rod can serve as a handle for a brush-type brush. When the tuft of bristles is connected to a drill, the brushing article may be placed on a drill and used for example as a polishing element. A screw as a functional piece is used to releasably connect the brush article to a separate bristle carrier. The functional part may also have an enlarged screw head with hexagon. The front surface of the receiving sleeve is placed on the flat side of the screw head to connect the functional part to the tuft of bristles.
    To keep the pressurized brush article in contact with a surface, the functional portion may be a pressure spring. Other embodiments of the functional part are also conceivable depending on the use in question of the brush article.
    To ensure a good connection with the tuft of bristles, particularly for functional parts which are not made of plastic and will not be melted at the same time, the functional part may have an undercut on the end facing the tuft. of hair. The molten plastic of the tufts of bristles flows into the undercut and thereby establishes, after cooling and hardening, a reliable connection with the functional part.
    Another embodiment of the device according to the invention, for which an autonomous protection is claimed, provides that an impact element made of quartz glass, glass-ceramic and / or an alloy thereof is provided for exerting an action on the ends of the tufted pile bristles held in a tuft receiving plate, a counter stop member is provided for impacting the free ends of the opposing tufts of the impact member, the anti-jamming abutment member and / or the impact member being positionable in the longitudinal direction of the bristles to effect the tufts of bristles and a heater is provided for heating the impact member and / or the ends of the tufts on the side. fixation and to melt tufts of hair and a cooling device for cooling the impact element and the tufts of hair after melting the tufts of hair ls.
    Such a device makes it possible to melt the tufts of bristles on the fixation side so as to be able to then coat them, during a subsequent working step, with plastic to form a brush body. The ends of the fastening side tufts may be impacted by the impact member while a heater is operating in the area of the impact member and the tufts of bristles are thereby heated and melted by the heat energy. penetrating the impact element. However, it is also possible to directly heat the ends of the tufts of the fastening side and then bring the impact member against the ends of the tufts heated and melted and to submit them to an impact.
    The ends of the tufts in contact with the impact member are cooled by the subsequent cooling until they are fully solidified. Cooling promotes the positive separation behavior between the impact element and the fused ends of the tufts. Adherence of the bristle material to the impact member is avoided by virtue of the material properties of the impact element which are as in the previously described receiving sleeve. There is only one element subjecting the tufts of bristles to an impact, which allows a simple mechanical assembly of the device.
    One embodiment provides for the tuft receiving plate and the impact member to be spaced apart from one another and for the impact member to be approximated to impact the tufts of heated bristles and deform them. on the tufting plate. The impact member is pressed against the tufts of heated and fused bristles protruding beyond the tuft receiving plate so that the free ends of the tufts are pressed flat to form mushroom heads.
    Another embodiment provides for a support plate with passage openings for the tuft of bristles to be provided between the tuft-receiving plate and the impact member, and the passage openings of the support plate each an enlarged anchoring cavity at their end facing the impact member and that the counter stop member can be positioned in the longitudinal direction of the tuft of bristles to subject the tuft of bristles to a force.
    With the counter stop member, the tufts of bristles are pressed against the impact member in the region of which the heater is disposed and whereby the ends of the tufts of the attachment side are melted. The melt material is pressed into the anchoring cavities such that anchors of deformed pile material form on the tufts of bristles on the attachment side, these anchors holding the tufts of bristles in the support plate.
    Subsequent cooling by the cooling device also contributes here to a clear separation of the ends of the tufts of the impact member.
    To avoid fusing tufts of bristles with the support plate, the tuft material should have a much lower melting point than the support plate material. However, it is also possible to use materials having similar melting points if a connection of the tuft of bristles with the support plate is desired when melted. This may, for example, be useful when the support plate with the tufts of bristles is to be used as a replacement head of a toothbrush. No further work steps are necessary in this case to attach the tufts of bristles to the support plate.
    By subjecting the support plate to an impact of the impact member, a flat outer surface with the ends of the melted tufts, deformed into anchors, is formed. This allows simple insertion of the support plate with the tufts of bristles, for example, into a brush body of a replacement toothbrush.
    The tuft receiving plate or support plate may preferably be an insert for insertion into an opening of an injection mold. This allows simple subsequent treatment of the tufted bristles, the tuft receiving plate being a reusable molded part, while the carrier plate is injection coated to form a same brush body and thus is a part of the finished brush.
    The support plate may also have edge-side attachment noses with which it is clipped into a housing of a brush body. Where appropriate, ultrasonic or high frequency welding may still occur to ensure an indelible bond between the brush body and the support portion.
    To make brushes with profiled bristle areas, the opposing abutment element may have profiling on its side impacting the tufts of bristles. The tufts of individual bristles are then brought, before being melted at their ends on the bond side, into corresponding positions so that the free ends of the tufts are oriented and positioned according to the desired profiling of the bristle area. Post-treatment of the hair zone, for example by grinding the tuft of hair, is therefore not necessary.
    Adhesion of the bristle material after cooling is avoided by the use of quartz glass, crystal glass, glass ceramic and / or an alloy thereof for the impact member. When removing the impact element in the longitudinal direction of the tufts, it may happen that individual tufts are offset from their position in the longitudinal direction for example by adhesion forces. To avoid this in a safe manner, it is appropriate that the impact element can be positioned transversally to the longitudinal direction of the bristles between a working position acting on the tufts of bristles and a waiting position shifted relative thereto , releasing the tufts of hair. By moving the impact member at right angles to the longitudinal direction of the bristles, the axial shifting of the tufts of bristles is surely avoided.
    The heating device may in particular have an infrared radiating body, a hot air blower, a laser, a high frequency generator or a thermal pulse generator. In the case of a thermal pulse generator, metal is heated by a flow of current. When using an infrared lamp, care shall be taken that the quartz glass, crystal glass, glass-ceramic and / or alloy thereof used for the receiving sleeve or the element to be impact has an appropriate permeability in the corresponding infrared range.
    The material of the bristles may be, for example, PA, during the manufacture of toothbrushes in particular PA6-12, PBT, PP, PE, PVC, PET or SAN.
    A tuft of bristles is generally composed of a plurality of individual filaments. A monofilament can however also be used, especially for technical brushes. In this special case, the tuft of hair is made up of a single filament.
    The tufts of bristles or their individual filaments may be tapered, rounded, uncoordinated, provided with chemical additives or provided with color markings.
    Tufts of bristles or their individual filaments may have a round, oval, polygonal or star-shaped contour.
    With regard to the method of manufacturing brushes or bristles with tufts of fused bristles at their end on the attachment side, the invention is characterized in that, on the one hand, a tuft of bristles and, on the other hand, a functional part arranged one behind the other in the longitudinal direction of the tuft of bristles is introduced into a receiving sleeve made of quartz glass, crystal glass, glass-ceramic and / or an alloy of these, in that heat is supplied at least in the region of contact of the tuft of bristles and the functional part in the receiving sleeve to melt the tuft of bristles and the tuft of bristles and the functional part are pressed against one another under the action of a force and that, thereafter, cooling takes place in the region of the receiving sleeve.
    This results in the advantages already mentioned in the description of the device according to the invention. The invention further relates to a brush or a brushing article with tufts of fused bristles at one end of the attachment side. This is characterized according to the invention in that the tufts of bristles are connected to the fastening side without bead to a functional portion by a cast connection.
    The functional part may consist in particular of plastic, wood or metal or any other solid material. The functional part may be, for example, a rod as a handle, a drill bit, a pressure spring or a screw. For a particularly reliable connection between the tuft of bristles and the functional part, especially when it is not made of plastic, the functional part may have an undercut at the end facing the tuft of bristles.
    Another embodiment of a brush or brush article according to the invention, for which self-protection is claimed, provides for the tufts of bristles to be placed in a support plate with passage openings for tufts. of bristles, the passage apertures of the plate each having an enlarged anchoring cavity at their opposite end to the useful end of the tuft of bristles and the tuft of bristles each having an enlarged end section by fusion, filling the cavity anchor, disposed in the outer contour of the support plate.
    Exemplary embodiments of the device and method according to the invention will be explained in more detail below on the basis of the drawings.
    It is shown, partly partially schematically, in FIG. 1 receiving sleeve with a tuft of bristles and a functional part, FIG. 2 the receiving sleeve of Figure 1 with the tuft of bristles and the functional part inserted, FIG. 3 the arrangement of Figure 2 with an impact member for the tuft of bristles and a heater, FIG. 4 the receiving sleeve with a cooling device, FIG. The brush article removed from the receiving sleeve, FIG. 6 in fig. 13 a tuft of bristles and a functional part before or after the connection of the parts to each other, FIG. 14 in FIG. 17 different parts of the method when fusing tufts of bristles held in a tuft receiving plate with a device according to the invention, and FIG. 18 in FIG. 23 different parts of the method when fusing tufts of bristles held in a tuft receiving plate and a support plate with a device according to the invention.
    A device designated in its entirety by 1a for making brushes or articles of brushing, which is shown in FIGS. 1 to 4 only very strongly simplified and schematically with the essential elements according to the invention, present according to the Figure 1 a receiving sleeve 2 in which a tuft of bristles 3 on the one hand and a functional portion 4 on the other hand can be inserted. The inner cross section of the receiving sleeve 2 is adapted in shape to the outer contour of the tuft of bristles 3 so that the tuft of bristles 3 inserted into the receiving sleeve is surrounded by shape complementarity by the sleeve. reception 2 (Figure 2). The receiving sleeve 2 may preferably have a round inner cross-section for receiving tufts of round bristles. Other cross sections corresponding to the contour of the bunch in question are however also possible, for example, polygonal, oval or star-shaped.
    A functional part 4 with the corresponding contour is inserted on the other side into the receiving sleeve 2 so that the tuft of bristles 3 and the functional part 4 touch each other inside the receiving sleeve 2.
    For the simplified insertion of the tuft of bristles 3 and the functional part 4, the receiving sleeve 2 has an insertion bevel 5 at its ends on the longitudinal side (FIG 1).
    The receiving sleeve 2 is made of quartz glass, crystal glass, glass-ceramic and / or an alloy thereof so that it has a high permeability for heat radiation and low heat conductivity. of contact.
    According to Figure 3, the end of the tuft side of the receiving sleeve 2 is closed by an impact member 6 and a force is exerted on the functional part 4 by another impact element not shown and only indicated by the arrow Pf1 of so that the tuft of bristles 3 and the functional part 4 are pressed against each other. At the same time, the region around the points of contact between the tuft of bristles 3 and the functional part 4 is heated by a heating device 7 approaching the receiving sleeve 2 and the material of the bristles is thus melted in this region of so that it can bind to the functional part 4. If the functional part 4 is also plastic and if it has a melting point similar to that of the pile material, it is also melted and the link between tuft of bristles 3 and functional part 4 is improved. Since the tuft of bristles 3 and the functional part 4 are arranged in shape complementarity in the receiving sleeve 2, the molten plastic material can not escape laterally beyond the contour of the tuft, so that no lateral bead is formed on the finished brush article 9 (Fig. 5) in this region where the tuft of bristles 3 has been melted.
    In addition, no unpleasant plastic odor is emitted during melting due to the material of the receiving sleeve 2.
    Thanks to the thermal properties of the receiving sleeve 2, the heat energy of the heating device 7 can penetrate properly into the cavity of the receiving sleeve 2 and cause the material of the bristles to melt.
    After melting, the receiving sleeve 2 and the tuft of bristles 3 therein are cooled with the functional part 4 now connected thereto by means of a cooling device 8 (FIG. 4). Since the receiving sleeve 2 has, due to its material properties different from that of the molten plastic material, a negative expansion coefficient, the plastic material detaches slightly from the receiving sleeve 2 during the cooling phase so that the finished brush article 9 consisting of the tuft of bristles 3 and the functional part 4 can easily be removed from the receiving sleeve 2. The smooth, pore-free surface of the receiving sleeve 2 also contributes to it.
    FIG. 6 shows a tuft of bristles 3 and a functional part 4 which is to be connected thereto and which is also designed in the form of a shank and has an undercut 11 at its end on the connection side, oriented towards the tuft of 3. When the plastic material of the tuft of bristles 3 melts, the melt flows into the region of the undercut 11 (Figure 7) so that a particularly good bond is formed between the tuft of bristles 3 and the functional part 4.
    In Figures 8 and 9, the functional portion 4 is a helical drill. The molten plastic flows into the area of the drill tip, which also allows good bonding. The brushing article 9 according to FIG. 9 may for example be a grinding brush or polishing brush which may be fixed to the drill bit on a drill for grinding or polishing a surface with the tuft of bristles 3.
    According to Figures 10 and 11, the functional portion 4 is designed as a screw with a hexagonal head 12. When connecting the functional portion 4 with the tuft of bristles 3, the receiving sleeve not shown here is on the front side of the hexagonal head 12 facing the tuft of bristles 3. For a better connection with the tuft of bristles 3, there is provided a projection 13 with an undercut 11 on the front side. A brushing article 9 according to FIG. 11 can for example be screwed onto a support and can be simply exchanged as a function of the wear of the tuft of bristles 3.
    Figures 12 and 13 show another variant in which a tuft of bristles 3 is connected to a functional part 4 designed as a pressure spring to give a brush article 9. When the two parts are bonded together, the molten plastic material of the tuft of bristles 3 flows in the helical windings of the functional part 4 or the functional part 4 is pressed into the molten bonding region. As a result, after the cooling and solidification of the plastic material, a good connection between the tuft of bristles 3 and the functional part 4 is formed.
    Figures 14 to 17 show, also strongly schematically, another embodiment of a device 1b for making brushes or brushes. In this device 1b, tufts of bristles 3 are inserted, in accordance with FIG. 14, into passage openings 15 of a tuft receiving plate 14. The tuft receiving plate 14 has an insertion bevel 5 at its ends. on the insertion side of the passage openings 15 to more simply insert the tufts of bristles 3. The lining of the tufts receiving plate 14 with tufts of bristles 3 can take place beforehand outside the device 1b and the plate of Tufts received 14 lined with tufts of bristles 3 is then fed into the device 1b.
    As can be seen in FIG. 15, the tuft receiving plate 14 is positioned at a distance from an impact member 16, the tufts of bristles 3 projecting from the tuft receiving plate 14 and abutting the element The free ends of the tufts, opposite to the impact member 16, are subjected to the action of a counter-stop member 17 and thereby held in position. The impact element 16 exerting an action on the tufts of bristles 3 is constituted, like the receiving sleeve 2 of the device 1a according to FIGS. 1 to 4, of quartz glass, crystal glass, glass-ceramic and / or of an alloy thereof and thus also has the previously described properties in terms of thermal conductivity, expansion coefficients and the nature of the surface.
    According to Figure 16, the ends of the tufts in contact with the impact member 16 are heated with a heater 7 and melted and the impact member 16 is simultaneously approached the tuft receiving plate 14 (arrow Pf2). As a result, the fused ends of the tufts of bristles 3 protruding from the tuft receiving plate 14 are transformed into mushroom heads 18.
    After transformation of the ends of the tufts, the plastic is cooled and hardened with the aid of a cooling device 8 (FIG. 17). The active cooling with the cooling device 8 promotes the separation behavior between the impact element 16 and the tufts of bristles 3.
    Then, the impact element 16 is moved along the arrow Pf3 transversely to the longitudinal direction of the bristles. The distance transverse to the longitudinal direction of the bristles makes it possible to avoid with certainty that the tufts of individual bristles 3 are offset in the longitudinal direction and are extracted from the tuft receiving plate 14. The tuft receiving plate 14 with the tufts of bristles 3 which now have deformed bristle ends into mushroom heads 18 may be introduced as a molded part into an injection mold and the mushroom heads 18 are injection-coated to form a brush body, the mushroom heads 18 to work with a high injection pressure without the risk of overmoldings in the region of the tuft of hair 3. The antagonist abutment member 17 acting on the free ends of the tufts of bristles 3 may also have profiling with which the tufts of bristles 3 can be profiled according to a desired profiling of the z one of the bristles of the finished brush.
    FIGS. 18 to 23 show a device 1b which is similar to the device 1b of FIGS. 14 to 17. However, a support plate 19 is additionally provided between the tuft receiving plate 14 and the impact element 16. Support plate 19 has passage openings 20 for tufts of bristles 3, insertion bevels 5 being provided on the insertion side on passage openings 20. Support plate 19 is adjacent to impact element 16. At their ends oriented towards the impact element 16, the passage openings 20 each have an enlarged anchoring cavity 21 which is clearly visible in the detailed representation according to FIG. 19.
    An opposing abutment member 17 exerts an action on the free ends of the tufts (Fig. 20). According to the arrow Pf4, the counter stop member 17 is moved towards the impact member 16 (Fig. 21), while the ends of the tufts in contact with the impact member 16 are heated and melted with a device 7. Here again, the heat energy of the heating device 7 is guided through the impact element 16 of quartz glass, crystal glass, glass-ceramic and / or an alloy thereof. Due to the pressure on the tufts of bristles 3, the molten plastic material moves into the anchoring cavities 21 and fills them.
    Then, a cooling device 8 (FIG. 22) is also used here to accelerate the cooling and hardening of the plastic material and to improve the separation properties between the plastic material and the impact element 16.
    Fig. 23 shows a detailed representation of an anchoring cavity 21 of the support plate 19, which cavity is filled with plastic of a tuft of molten bristles 3. The ends of the tufts deformed into an anchor 22 on the fixation side improve the holding of the tufts of bristles 3 in the support plate 19. Correspondingly to FIG. 17, the impact element 16 can according to FIG. 22, after curing. of the plastic material, be removed from the support plate 19 transversely to the longitudinal direction of the bristles (arrow Pf4).
    The support plate 19 may be introduced into an injection mold and injection-coated to form a brush body. It is also possible to insert the support plate (19) in a receiving opening of a prefabricated brush body. A snap or snap connection can be established with lateral attachment noses 23. Subsequent treatment of the support plate 19 with the tufts of bristles 3 it contains is also simplified because the ends of the fixing side of the tufts of bristles 3 with the anchors 22 in the anchoring cavities 21 do not protrude beyond the outer contour of the support plate 19 but terminate flush with it.
