Description

[0001] The invention relates to a dividing device for separating bristle bundles from a supply of loose bristle filaments, wherein the dividing device comprises a material box for receiving a supply of loose bristle filaments, a bundle divider with at least one dividing notch and at least one counterpart, wherein the bundle divider with the at least one dividing notch is movable through a dividing area on the material box in order to divide bristle bundles, and wherein the at least one dividing notch with the bundle divider is movable along the counterpart into a bundle discharge position.

[0002] Furthermore, the invention also relates to a brush manufacturing machine with such a dividing device.

[0003] Compartment devices and brush manufacturing machines of the type mentioned above are known from the prior art in various embodiments.

[0004] For example, DE 10 2016 011 337 A1 discloses a dividing device for a brush manufacturing machine, wherein the dividing device comprises a bundle divider movable relative to a material box and a counterpart fixed relative to the movable bundle divider. The bundle divider has at least one dividing notch on its front side, which in its operating position faces the material box and the supply of loose bristle filaments held therein, and can be moved past the supply with the at least one dividing notch to divide a bristle bundle from the supply and guided along the counterpart to transfer the bristle bundle into a bundle discharge position.

[0005] The bundle divider notch has two opposing knife edges oriented transversely to the direction of movement of the bundle divider, which define a notch opening of the divider notch. The counterpart of the divider device known from DE 10 2016 011 337 A1 is provided with a dividing edge facing the bundle divider.

[0006] In the known devices, a bundle divider with its at least one dividing notch is moved through a dividing area on a material box filled with bristle filaments to separate bristle bundles from a material box. The dividing notch is filled with bristle filaments by the pressure of the filaments in the material box. The bristle filaments located in the dividing notch together form a bristle bundle.

[0007] As soon as the compartment notch filled with bristle filaments leaves the compartment area in front of the material box, it moves in front of the counterpart and is closed by it, so that a bristle bundle arranged in the compartment notch is securely held on its way to the bundle discharge position. The bristle bundle is transported by the bundle divider along the counterpart to a subsequent processing step. For example, the bristle bundle can be fed to a tamping tool of a brush manufacturing machine and, with the help of this tamping tool, anchored in a brush body together with a fastening anchor.

[0008] In another method of brush manufacturing, the bristle bundle is fed by means of a bundle divider to a tool that deposits the bristle bundle in a defined manner into a cassette or other container. However, it is also possible to remove the bristle bundle arranged in the divider notch using a suction device and feed it into a cassette or other holder. This method is frequently used in connection with the so-called armature-less manufacturing of brushes.

[0009] If particularly fine bristle filaments are to be processed, which, for example, have a diameter of less than 0.1 mm, existing dividing devices for separating bristle bundles may reach their limits.

[0010] The previously known partitioning devices enable the reliable processing of relatively fine bristle filaments with a diameter of at least approximately 0.1 mm. When processing bristle filaments with a diameter of less than 0.1 mm (4 mils), the partitioning devices of the prior art can cause the particularly fine bristle filaments to enter a gap between the bundle partition and the counterpart.

[0011] In the prior art partitioning devices, a gap exists between the bundle divider and the counterpart to prevent friction between the bundle divider and the counterpart. Despite high precision in the adjustment of the partitioning device, this gap can become so large during operation due to tolerances and / or vibrations that bristle filaments with a diameter of less than 4 mils, i.e., less than 0.1 mm, enter the gap. This problem with the prior art partitioning devices will be discussed further below using the following examples: Fig. 3 to 11 and 12 to 20 are explained in more detail.

[0012] As soon as the gap reaches a size on the order of half a filament diameter, the risk increases that the bristle filaments will be damaged during sectioning and / or become trapped between the bundle divider and the counterpart. This can lead to excessive contamination of the sectioning device and thus impair brush production.

[0013] The object of the invention is therefore to provide a dividing device for separating bristle bundles and a brush manufacturing machine that enables reliable dividing even of bristle bundles made of particularly fine bristle filaments.

[0014] To solve the problem, a dividing device for separating bristle bundles from a supply of loose bristle filaments is proposed, which has the means and features of the independent claim directed to such a dividing device. Thus, to solve the problem, a dividing device is proposed that comprises a material box for receiving a supply of loose bristle filaments, a bundle divider with at least one dividing notch, and at least one counterpart. The bundle divider can be moved with the at least one dividing notch through a dividing area on the material box to separate bristle bundles. The at least one dividing notch is movable with the bundle divider along the counterpart into a bundle dispensing position. According to the invention, the bundle divider has a profile on its front face facing the counterpart, with which the bundle divider overlaps the counterpart when the dividing notch is located on the counterpart.

[0015] The profile formed on the bundle divider, with which the bundle divider overlaps the counterpart, prevents a straight gap between the counterpart and the bundle divider that would be accessible to bristle filaments. Due to the overlap between the bundle divider and counterpart, the counterpart can engage with the profile of the bundle divider, at least when the bundle divider is positioned with its dividing notch against the counterpart. This ensures that the gap between the counterpart and the bundle divider does not follow a straight path, but rather a path corresponding to the geometry of the profile, preventing the entry of the straight bristle filaments.

[0016] The dividing device according to the invention thus enables the reliable dividing of bristle bundles from a supply of loose bristle filaments that have a relatively small diameter, for example, a diameter of less than 0.1 mm. This enables the reliable production of brushes with a bristle covering made of correspondingly fine bristle filaments.

[0017] As previously indicated, the counterpart can engage in the profile of the bundle divider if the counterpart has a compartment notch.

[0018] The profile is particularly advantageously designed adjacent to at least one compartment notch. This ensures that the gap between the bundle divider and one or more counterparts in the area of ​​the at least one compartment notch has a geometry that prevents the accidental entry of bristle filaments.

[0019] In one embodiment of the dividing device, the profile is formed on both sides of the at least one dividing notch in the direction of movement of the bundle divider. A bundle divider with such a profile on both sides of the at least one dividing notch is suitable for dividing bristle bundles from a supply of loose bristle filaments, wherein the bundle divider is moved in an alternating motion, possibly several times, through the dividing area past the material box and thereby passes counterparts with the at least one dividing notch located on both sides of the dividing area.

[0020] To enable alternating movement of the bundle divider in front of the material box and its compartment area, it is advantageous if the compartment device has a counterpart on both sides of the compartment area of ​​the material box with respect to a direction of movement of the bundle divider through the compartment area. The counterparts can then overlap with the profile of the bundle divider when the compartment notch of the bundle divider is arranged on the respective counterpart.

[0021] This prevents fine bristle filaments from getting into the gap between the bundle divider and the counterparts on both sides of the compartment area on the material box.

[0022] In a preferred embodiment of the partitioning device, the profile has at least two profile projections spaced apart from each other transversely to the direction of movement of the bundle partition, with which the bundle partition overlaps the counterpart on two opposite sides of the counterpart. A gap between the counterpart and the bundle partition then has a cross-section whose shape deviates from a rectangular cross-sectional shape and particularly effectively prevents the accidental entry of bristle filaments. When viewing the gap imaginarily in the direction of the longitudinal extension of the bristle filaments located in the partition notch, the gap is not a straight, continuous gap.

[0023] The profile can have a profile groove, particularly between its two profile projections spaced apart transversely to the direction of movement of the bundle divider, in which the counterpart is arranged with a compartment notch present on the counterpart. Such a profile groove on a front face of the bundle divider facing the counterpart allows for a particularly large overlap of the counterpart on two different sides, thus creating a gap, for example C-shaped or V-shaped in cross-section, between the bundle divider and the counterpart. This can reliably prevent the entry of bristle filaments into the gap formed between the counterpart and the bundle divider.

[0024] At least one compartment notch can then be formed within the profile groove of the bundle divider profile. At least one compartment notch can penetrate the bottom of the profile groove.

[0025] In a preferred embodiment of the partitioning device, the profile of the bundle divider has at least one inclined surface that connects a profile end face with the at least one partition notch. Along this inclined surface, bristle filaments that have not reached the partition notch but have already left the material box can be pushed back into the material box by moving the bundle divider relative to its counterpart. The at least one inclined surface of the profile can, for example, be a flat inclined surface, in particular a chamfer, and / or an inclined surface curved, in particular around a radius.

[0026] In this context, it can be advantageous if at least one counterpart has a counter-sloping surface along which the bristle filaments that have not entered the compartment notch of the bundle divider can be pushed back into the material box. The counter-sloping surface can, for example, be a flat counter-sloping surface or a counter-sloping surface curved, particularly around a radius.

[0027] The profile, in particular the profile groove, can extend over an entire section of the front face of the bundle divider that passes over the counterpart. Within the profile, particularly within the profile groove, several compartment notches can be formed, which can be moved through the compartment area to receive bristle filaments from the material box of the bundle divider. The multiple compartment notches can be spaced apart from each other on the front face of the bundle divider in the direction of movement of the bundle divider.

[0028] The profile groove of the bundle divider can, for example, have a V-shaped cross-section. The counterpart can be arranged within the V-shaped cross-section if the bundle divider is positioned with its dividing notch against the counterpart.

[0029] The counterpart can have a projection, preferably V-shaped in cross-section, on its side facing the bundle divider, with which the counterpart engages in the profile, preferably in the profile groove, of the bundle divider.

[0030] The geometry of the counterpart can thus be matched to the geometry of the profile on the front face of the bundle divider facing the counterpart. This promotes a gap between the counterpart and the bundle divider with a geometry that particularly effectively prevents bristle filaments from entering the gap between the counterpart and the bundle divider.

[0031] A gap formed between the bundle divider and its counterpart can, for example, have a V-shaped cross-section if the profile groove and counterpart are appropriately designed. Such a gap is then not readily accessible to an unbent bristle filament that has not entered the divider notch during the separation of bristle bundles.

[0032] To avoid damage to bristle filaments during bristle filament separation, it may be advantageous if the bundle divider has at least one knife edge oriented transversely to the direction of movement of the bundle divider, which is rounded transversely to its longitudinal extent, for example with a radius of 0.003 mm to 0.03 mm.

[0033] For particularly gentle separation of bristle filaments from the material box of the dividing device, it may be advantageous if at least one counterpart has at least one dividing edge oriented transversely to the direction of movement of the bundle divider, which is rounded transversely to its longitudinal extent, for example with a radius of 0.003 mm to 0.03 mm.

[0034] The bundle divider can have two knife edges oriented transversely to the direction of movement of the bundle divider, which define a notch opening of the division notch. Both knife edges can be rounded in the manner described above. It is particularly advantageous if a knife edge located at the rear of the bundle divider, in the transport direction of the bristle bundles to the previously mentioned bundle discharge position, and which defines the division notch of the bundle divider, is correspondingly rounded.

[0035] With this type of knife edge, there is an increased risk that a bristle filament, which does not fully enter the dividing notch when being separated from the material box, will become trapped between the knife edge of the bundle divider and the dividing edge of the counterpart and be damaged by the edges. The rounded design of the knife edge, and preferably also the dividing edge, can reduce this risk of damage to the bristle filament.

[0036] For trouble-free separation of bristle bundles from the material box, it can also be advantageous if at least one surface of the bundle divider facing the counterpart is polished. This at least one surface can, for example, have an average roughness value or a surface roughness value of Ra less than 0.1, preferably Ra less than 0.05, and particularly preferably Ra less than 0.02.

[0037] The counterpart can also have a polished surface facing the bundle divider. This surface can, for example, have an average roughness value or a surface roughness value of Ra less than 0.1, preferably Ra less than 0.05, and particularly preferably Ra less than 0.02.

[0038] In one embodiment of the compartment device, the bundle divider and / or the at least one counterpart have at least one fastening interface for fixing an assembly jig. The assembly jig can be at least temporarily part of the compartment device.

[0039] As a mounting interface, the bundle divider and / or the counterpart can each have at least one bore by means of which the mounting jig for setting the distance between the bundle divider and the counterpart of the dividing device can be temporarily fixed. This can significantly simplify the setup of the dividing device for separating bristle bundles.

[0040] Depending on the application, the bundle divider can be designed, for example, as a circular arc divider, a compartment slider or a compartment disc.

[0041] If the bundle divider is designed as a circular arc divider, it can, for example, be pivoted back and forth around a pivot axis in an alternating movement between the compartment area at the material box and the bundle discharge position.

[0042] If the bundle divider is designed as a compartment slider, it can be moved past the material box in a straight line to divide bristle bundles and moved to the bundle discharge position to discharge bristle bundles.

[0043] In another embodiment of the compartment device, it features a bundle divider designed as a compartment disc. A compartment disc enables compartment movement in the form of an alternating pivoting motion or a rotating motion. Both a circular arc divider and a compartment slider, as well as a compartment disc, can each have more than one compartment notch.

[0044] To solve the problem, a brush manufacturing machine with a dividing device for separating bristle bundles is also proposed, according to one of the claims directed to such a dividing device. In one embodiment of the brush manufacturing machine, with which bristle bundles can be stuffed into prepared bristle carriers to manufacture brushes, it is provided that the brush manufacturing machine has at least one stuffing tool. The stuffing tool can be configured to stuff bristle bundles, transferred to the stuffing tool by the bundle divider of the dividing device, into a prepared bristle carrier.

[0045] The brush manufacturing machine can further include a clamping device for mounting at least one bristle carrier to be fitted with bristle bundles. The clamping device allows the at least one bristle carrier to be clamped in a machining position, in particular on a tamping tool of the brush manufacturing machine, such as the one mentioned above.

[0046] In an embodiment of the brush manufacturing machine, in which the separated bristle bundles are transported to a downstream processing station of the brush manufacturing machine by a fluid flow, for example, a gas or air flow, the brush manufacturing machine may be equipped with a suction device. The suction device is designed to transport bristle bundles separated by the dividing device to a downstream processing station of the brush manufacturing machine by means of a vacuum.

[0047] The extraction device can, for example, include at least one source of negative pressure and / or at least one transport line through which the bristle bundles can be extracted and transported from a compartment notch of the bundle divider in the bundle discharge position by means of negative pressure.

[0048] The invention is described in more detail below with reference to exemplary embodiments, but is not limited to these. Further exemplary embodiments result from combining the features of one or more claims with one another and / or from combining one or more features of the exemplary embodiments.

Fig. 50 to 54 different representations of a bundle divider and a counterpart of a further compartment device according to the invention, wherein the profile of the bundle divider has curved inclined surfaces that connect the compartment notch with profile end faces of the profile, Fig. 55 to 58 different individual part representations of an assembly jig for setting a distance between the bundle divider and the counterpart of the in the Fig. 1 and Fig. 2 compartment device shown as well as Fig. 59 to 62 different individual representations of an assembly jig for setting a defined distance between the bundle divider and the counterpart of the in the Fig. 29 and Fig. Compartment device shown in section 30.

[0049] The Fig. 1 and Fig. Figures 2 and 21-62 show at least parts of partitioning devices, each designated as 1, for partitioning bristle bundles from a supply 2 of loose bristle filaments 3.

[0050] The compartment devices 1 each comprise a material box 4 for receiving the supply 2 of loose bristle filaments 3, a bundle compartment 5 with at least one compartment notch 6 on its front 11 and at least one counterpart 7.

[0051] The bundle divider 5 can be moved with its at least one compartment notch 6 through a compartment area 8 on the material box 4 to divide bristle bundles from the supply 2 in the material box 4. The at least one compartment notch 6, together with the bristle bundle contained therein, can then be moved with the bundle divider 5 along the counterpart 7 into a bundle discharge position. Bundle discharge positions are located in the Fig. 1 and Fig. 2, 25 and 26 are shown and labelled 33.

[0052] In the respective bundle discharge position 33, a separated bristle bundle can then be transferred to a downstream tool or to a downstream processing step.

[0053] In the case of the in the Fig. 1 and Fig. In the partitioning device 1 shown in Figure 2, the bristle bundle is transferred by means of the bundle partitioner 5 to a stuffing tool 9 of a brush manufacturing machine designated as a whole by 10, on which the partitioning device 1 is arranged.

[0054] For separating bristle bundles made of particularly fine bristle filaments 3, the bundle dividers 5 according to the invention have a profile 12 on their front side 11 facing the respective counterpart 7 adjacent to the dividing notch 6, with which the respective bundle divider 5 overlaps the counterpart 7 when the dividing notch 6 is located on the counterpart 7.

[0055] This overlap of the counterpart 7 creates a gap 28 between the bundle divider 5 and the counterpart 7, the shape of which can effectively prevent even comparatively fine bristle filaments 3 from entering this gap 28.

[0056] The Fig. Figures 3-11 and 12-20 show a bundle divider 5 on a counterpart 7 of a compartment device 1, which represents the state of the art.

[0057] These figures illustrate that the bundle compartment 5 does not have a comparable profile 12 on its front face 11 facing the counterpart 7, and that the counterpart 7 does not overlap when the compartment notch 6 is located on the counterpart 7. Accordingly, there is a gap between bundle compartment 5 and counterpart 7.

[0058] The Fig. Figures 3-11 show the separation of bristle bundles from bristle filaments 3, which, for example, have a diameter of 0.1 mm or larger.

[0059] A gap between the bundle divider 5 and the counterpart 7 is maintained during the assembly of the bundle divider 5 and the counterpart 7 according to the Fig. 6 and Fig. 7 is initially set to approximately 0.04 mm. Due to the movement of the bundle divider 5 relative to the counterpart 7 during the separation of bristle bundles, vibrations can occur during operation of the dividing device 1, and thus also changes in the distance between the bundle divider 5 and the counterpart 7.

[0060] This is in the Fig. 9 and Fig. 11 shown. Fig. Figure 9 shows a maximum expected distance between the bundle divider 5 and the counterpart 7, which here is approximately 0.08 mm. This is shown in Fig. The bristle filament 3 shown also has a diameter of about 0.1 mm, so that the risk of bristle filaments 3 getting into the gap 28 is low even when the maximum distance between bundle divider 5 and counterpart 7 occurs.

[0061] Fig. Figure 11 shows a possible minimum distance between the bundle divider 5 and the counterpart 7, which can be set during operation of the divider device 1 and is, for example, 0.005 mm.

[0062] The Fig. Figures 12-20 show compartment device 1 from the Fig. 3-11 when separating bristle bundles from finer bristle filaments 3 whose diameter is less than 0.1 mm, for example 0.077 mm = 3 mils. Fig. Figure 18 shows the situation in which a maximum distance occurs between bundle compartment 5 and counterpart 7.

[0063] It is clearly evident that the gap is so large that the comparatively fine bristle filament 3 can enter the gap 28 between the counterpart 7 and the bundle divider 5. If a bristle filament 3 is pulled into the gap 28 between the bundle divider 5 and the counterpart 7, this can lead to significant contamination of the divider device 1 and the brush manufacturing machine 10 equipped with it, which can ultimately result in quality impairments in brush production and also downtime of the divider device 1.

[0064] The compartment devices 1 shown in the remaining figures effectively avoid, due to the design of their bundle compartments 5 and counterparts 7, the formation of a gap 28 between the respective bundle compartment 5 and the respective counterpart 7, into which a fine bristle filament 3 can enter, which, for example, has a diameter of less than 0.1 mm, for example, 0.077 mm.

[0065] In the Fig. In the embodiments of compartment devices 1 shown in Figures 21, 22, 23, 24, 27, 28, 31, 32 and 33-54, the respective counterpart 7 engages in the profile 12 of the bundle compartment 5 assigned to the counterpart 7 when the compartment notch 6 is located on the counterpart 7.

[0066] In the Fig. In the embodiments of bundle dividers 5 shown in Figures 21-46 and 50-54, the respective profile 12 has two profile projections 13 and 14 spaced apart from each other transversely to the direction of movement of the bundle divider 5, with which the respective bundle divider 5 overlaps the counterpart 7 associated with it on two opposite sides of the counterpart 7.

[0067] The one in the Fig. The bundle compartment 5 shown in figures 47 to 49 has a profile 12 with a single profile projection 13. With this profile projection 13, the bundle compartment 5 overlaps the counterpart 7 when the compartment notch 6 is passed by the counterpart 7.

[0068] The profiles 12 are formed on both sides of the respective compartment notch 6 of the bundle divider 5 in the direction of movement of the bundle divider 5. The profiles 12, which have two spaced-apart profile projections 13 and 14, comprise a profile groove 15 in which the respective counterpart 7 is arranged with a compartment notch 6 located on the counterpart 7.

[0069] The Fig. Figures 24, 28, 32, 33-41, 42-46 and 50-54 show that the compartment notches 6 are formed within the profile groove 15 of the respective bundle compartment 5.

[0070] The profiles 12 have inclined surfaces 16 and 17 that connect a profile end face 18 of the profile 12 with the respective compartment notch 6. These inclined surfaces 16 and 17 can be formed as chamfers 19 in the form of planar inclined surfaces or, as in the case of the one in the Fig. 50-54 shown embodiment of a bundle divider 5, as inclined surfaces 20 bent around radii.

[0071] Along the inclined surfaces 16 and 17, bristle filaments 3 can enter the respective dividing notch 6 from the supply 2 of loose bristle filaments 3, which is arranged in the material box 4 of the respective dividing device 1. The bristle filaments 3 that do not enter the dividing notch 6 can then be pushed back into the material box 4 along the counterpart 7 when the bundle divider 5 is moved past the counterpart 7.

[0072] Planar inclined surfaces 16 and 17 in the form of chamfers 19 are, for example, in the Fig. 22, 24, 28, 32, 33, 37, 39, 41, 45 to 47 can be identified.

[0073] In the Fig. Figures 22, 24, 28, 32, 33, 37, 39, 41, 45 to 47 also show that the inclined surfaces 16 and 17 are formed at the profile bore origins 13 and 14 of the respective profile 12 and are thus formed on both sides of the compartment notch and also on both sides of the profile groove 15, if present. The counterparts 7 also have, according to the figures, an inclined surface 21 on their side facing the material box 4, in particular in the form of a chamfer, i.e., a planar inclined surface, and / or in the form of an inclined surface curved around a radius.

[0074] The profiles 12, in particular the profile grooves 15, are each formed over the entire section of the front face 11 of the respective bundle compartment 5 that passes over the counterpart 7.

[0075] The profile grooves 15 of the bundle dividers 5 shown in the figures have a V-shaped cross-section. The corresponding counterparts 7 have a projection 22 with a corresponding V-shaped cross-section on their side facing the respective bundle divider 5. The projection 22 of each counterpart 7 engages in the profile 12, namely in the profile groove 15 of its associated bundle divider 5.

[0076] The bundle dividers 5 shown in the figures each have knife edges 23 oriented transversely to the direction of movement of the bundle divider 5.

[0077] In the Fig. 23 and Fig. In the embodiments of bundle dividers 5 shown in Figures 24 and 42-46, the knife edges 23, which also define the compartment notches 6 of the bundle dividers 5, are rounded transversely to their longitudinal extent, for example with a radius of 0.003 mm to 0.03 mm.

[0078] The counterparts 7 have a dividing edge 24 oriented transversely to the direction of movement of their associated bundle divider 5. In the case of the Fig. In embodiments of counterparts 7 shown in Figures 23 and 24 and 42-46, the dividing edges 24 are rounded with a radius of, for example, 0.003 mm to 0.03 mm.

[0079] The rounded shapes of the knife edges 23 and dividing edges 24 promote a particularly gentle separation of bristle bundles from bristle filaments 3, as the rounding reduces the risk of damage to the bristle filaments 3.

[0080] The bundle dividers 5 and the counterparts 7 have mutually facing surfaces that are polished. These surfaces can, for example, have an average roughness value or surface roughness value of Ra less than 0.1, preferably Ra less than 0.05, and particularly preferably Ra less than 0.02.
