Description

[0001] Bundle separating device and method for separating bristle bundles and bristle product manufacturing machine

[0002] The invention relates to a bundle separating device for separating bristle bundles from a supply of loose bristle filaments, a bristle goods manufacturing machine with such a bundle separating device and a method for separating bristle bundles from a supply of loose bristle filaments.

[0003] In the manufacture of bristle goods, such as brushes, especially toothbrushes, brooms and also paintbrushes, bundles of bristles are attached to a bristle carrier as bristle trim.

[0004] In the mechanical production of bristle products, bundle separating devices of the type mentioned above are used to prepare the bristle bundles. These are designed to separate bristle bundles from a supply of loose bristle filaments. For this purpose, a bundle separator, which has at least one separating notch, is moved past the supply of loose bristle filaments in a separating movement. Bristle filaments then enter the at least one separating notch and form a bristle bundle there. If bristle products are to be equipped with bristle bundles which have a cross-sectional shape which deviates from a circular shape, the bristle bundles can be reshaped before being attached to the bristle carrier of the respective bristle product.

[0005] The object of the invention is to provide a bundle separating device and a method for separating bristle bundles, which enable the provision of bristle bundles which have a cross-sectional shape deviating from a circular shape.

[0006] To achieve this object, a bundle separating device is first proposed having the features of the independent claim directed to such a bundle separating device. To achieve this object, a bundle separating device for separating bristle bundles from a supply of loose bristle filaments is thus specifically proposed, comprising a bundle separator which has at least one separating notch and can be moved past the supply of loose bristle filaments in a separating movement, wherein the bundle separating device has a bundle forming device which is designed to reshape a bristle bundle located in the at least one separating notch.

[0007] The bundle forming device may be configured to reshape the bristle bundle while it is still disposed within the compartment notch.

[0008] The shaping of the bristle bundle can preferably take place in the dividing notch or adjacent to the dividing notch, but still at the bundle divider.

[0009] In one embodiment of the bundle dividing device, the bundle forming device can have at least two mutually associated forming tools with which a bristle bundle arranged in the at least one dividing notch can be formed.

[0010] At least one of the forming tools can be movable in a forming movement relative to the bundle separator and / or to the forming tool assigned to it.

[0011] The at least two forming tools can each have a forming area for each dividing notch of the bundle divider. The forming areas of the forming tools are assigned to one another and together form a negative mold of the target shape into which the cross-section of the bristle bundle is to be formed. The mutually assigned forming areas of the at least two forming tools of the bundle forming device are then designed according to the desired cross-sectional shape of the bristle bundles.

[0012] At least one forming tool can have, in particular on a flat side, at least one projection for supporting a bundle of bristles located in the forming area, preferably with each forming area being assigned such a projection.

[0013] A forming tool can have a guide surface for the other forming tool associated with it. This enables precise positioning of the forming tools for forming the bristle bundles. The guide surface can preferably be arranged in a plane positioned between a plane of movement of the bundle separator and the other forming tool.

[0014] The bundle-forming device can be configured, particularly through its forming tools, to reshape a bristle bundle to be reshaped in a fastening-side bundle section with which the bristle bundle protrudes from the at least one separation notch of the bundle separator. Thus, the bundle-forming device can act on the bristle bundle still located in the separation notch in order to reshape it.

[0015] In one embodiment of the bundle separating device, the shaping tools are designed as clamps. The shaping tools can therefore not only reshape the at least one bundle of bristles arranged in the separating notch, but also hold it in place. This can facilitate further handling of the bundle of bristles and increase the efficiency of the bundle separating device, since the bundle separator can be removed from the bundle of bristles to separate at least one further bundle of bristles as soon as the bundle of bristles has been gripped and held by the shaping tools. The bundle forming device can be configured, in particular by means of its at least two shaping tools, to remove a bundle of bristles located in the at least one separating notch.

[0016] For this purpose, the at least two forming tools of the bundle forming device can be configured to perform a removal movement relative to the bundle separator. The removal movement of the forming tools can be oriented transversely to a pivot axis or a rotation axis of the bundle separator and / or can be caused by a drive, in particular a linear drive, of the bundle forming device.

[0017] With the aid of the forming tools of the bundle forming device, a bristle bundle arranged in the separation notch can be removed from the separation notch. The removal can take place before, after, or even during the forming of the bristle bundle. After the bristle bundle has been removed using the forming tools of the bundle forming device, the bundle separator can be moved back toward the supply of loose bristle filaments with its at least one separation notch to separate further bristle bundles.

[0018] In one embodiment of the bundle separating device, it has a melting station with at least one heating element for melting the fastening-side ends of bristle bundles. By melting the fastening-side ends of the bristle bundles, the bristle filaments contained in the bristle bundles can be connected to one another. Furthermore, the melting can also produce a fastening head on the fastening-side end of the bristle bundle, which can simplify fastening of the bristle bundle to a bristle carrier of a bristle product. The melting station can preferably be arranged near the bundle forming device. The melting station can have at least one heating element that can be moved from an initial position into a use position and with which the fastening-side ends of bristle bundles can be melted.

[0019] In order to protect the bundle separator and / or non-melting sections of the bristle bundles from the effects of heat when fusing the fastening-side ends of bristle bundles, it can be advantageous if the bundle forming device, in particular its at least two forming tools, is / are designed as a heat shield. For example, the forming tools can shield the bundle separator and / or non-melting sections of the bristle bundles from the heating element of the melting station when the melting station is in use and thus act as a heat shield. For this purpose, the at least two forming tools of the bundle forming device can be designed as flat structures, at least in sections.If the forming tools circumferentially enclose at least one bristle bundle for forming, they can shield the elements arranged beyond the forming tools starting from the melting station, that is to say in particular the sections of a bristle bundle which are not to be melted and / or the bundle separator, from the at least one heating element of the melting station.

[0020] The bundle dividing device may comprise a pressing device which is designed to press bundles of bristles out of the at least one dividing notch.

[0021] The squeezing device can simplify the removal of the bristle bundles from the at least one dividing notch of the bundle divider. In particular when a bristle bundle adheres to the at least one dividing notch, the squeezing device enables reliable removal of the bristle bundle from the dividing notch. The squeezing device can preferably be used when a bristle bundle is held by means of the bundle forming device, in particular by means of its at least two forming tools. Through the interaction of the bundle forming device and the squeezing device, the bristle bundle can then be removed from the at least one dividing notch particularly safely and gently. The bundle divider can be arranged in a plane between the squeezing device and the bundle forming device.Thus, the squeezing device and the bundle forming device can act on a bundle of bristles to be removed from the at least one compartment notch at two bundle sections projecting from the compartment notch on different flat sides of the bundle divider in order to remove the bundle of bristles from the compartment notch.

[0022] The bundle separating device can have a suction device for sucking and transporting bristle bundles, with which the bristle bundles can be transported from the bundle forming device to a target position. Bristle bundles formed with the aid of the bundle forming device can then be transported directly from the bundle forming device to a desired target position. The suction device can comprise a vacuum source for this purpose.

[0023] In an advantageous embodiment of the bundle separating device, the suction device is provided with a plurality of transport lines. The suction device can, for example, have a number of transport lines corresponding to the number of separating notches. In this way, a plurality of bristle bundles provided with the bundle separator can then be transported away via the transport lines in one suction process. If a bundle separator is used which has only a single separating notch, a suction device with only one transport line can be used. If the bundle separator has a plurality of separating notches, it is advantageous for the simultaneous removal of the bristle bundles if the suction device has a corresponding number of transport lines.

[0024] In this context, it should be mentioned that the bundle-forming device of the bundle-dividing device can also be configured for the simultaneous forming and preferably the simultaneous removal and / or holding of a number of bristle bundles corresponding to the number of dividing notches of the bundle divider. Thus, all of the bristle bundles prepared by the bundle divider in a dividing process can be formed in one step using the bundle-forming device and then, in a subsequent step, simultaneously sucked out of the bundle-forming device using the suction device and transported to their respective target position.

[0025] In one embodiment of the bundle separating device, it is provided that the at least one transport line, in particular a plurality of transport lines, of the suction device can be moved from an initial position into a suction position on the bundle forming device. In this way, the one or more transport lines can be moved into their suction position when the bristle bundles are ready for removal. If the one or more transport lines are not required, they can remain in their initial position outside the working area of ​​the bundle forming device.

[0026] At least one transport line of the suction device can be configured to rotate the bristle bundles by a defined angle around their longitudinal axis on their way to the target position, thereby bringing them into a defined target orientation. The transport line can thus be used for the targeted orientation of the bristle bundles.

[0027] The at least one transport line can have an inner transport lumen through which the bristle bundles can be transported to their target position, which is twisted by a defined angular amount along its path to the target position. A bristle bundle transported through the transport line is then automatically rotated by the angular amount by the torsion of the transport lumen and can thus be oriented accordingly as it passes through the transport line.

[0028] At least one transport line can have an internal cross-section that corresponds to the cross-section of a deformed bristle bundle. The transport line is then matched to the cross-section of the bristle bundle to be transported. Because the shape of the internal cross-section of the transport line is matched to the cross-section of the bristle bundle, the bristle bundle can bear optimally against an inner side of the transport line. A negative pressure applied to transport the bristle bundle through the transport line can then be transferred to the bristle bundle particularly well and largely without loss.

[0029] The bundle separating device described above can be part of a bristle goods manufacturing machine.

[0030] To achieve the object, a bristle goods manufacturing machine with at least one bundle separating device according to one of the claims directed to such a device is also proposed.

[0031] To achieve the object, a method for separating bundles of bristles from a supply of loose bristle filaments is also proposed, which has the means and features of the independent claim directed to such a method. To achieve the object, a method for separating bundles of bristles from a supply of loose bristle filaments is thus proposed, in which a bundle separator with at least one separating notch is moved past the supply of loose bristle filaments in a separating movement, bristle filaments entering the at least one separating notch and forming a bundle of bristles there. The bundle of bristles located in the separating notch is then shaped into a target cross-sectional shape using a bundle forming device. When carrying out the method, a bundle separating device according to one of the patent claims directed to such a device can be used.

[0032] The shaping of the bristle bundle can begin while the bristle bundle is still arranged in the dividing notch. The bristle bundle can be shaped in the dividing notch. The bundle shaping device can shape the bristle bundle, in particular, by acting on a fastening-side section of the bristle bundle that protrudes from the dividing notch transversely to a plane of movement of the bundle divider.

[0033] In one embodiment of the method, the bristle bundle can be removed from the dividing notch using the bundle forming device and can be reshaped before, during or after this process.

[0034] A fastening-side end of the bristle bundle can be fused with a heating element of a melting station. By fusing the fastening-side ends of the bristle bundles, it is possible to bond the bristle filaments gathered in the bristle bundles together and / or to create a fastening head at the fastening-side end of the bristle bundle.

[0035] The bundle forming device, particularly through its forming tools, can be used as a heat shield when fusing the fastening-side end of at least one bristle bundle. The forming tools can be arranged between the at least one heating element of the melting station and the bundle separator. With the aid of the forming tools in their function as a heat shield, elements located beyond the forming tools, in particular the bundle separator and also sections of the bristle bundle that are not to be melted, can be protected from the heat of the heating element of the melting station.

[0036] The bundle of bristles can be removed from the bundle forming device using a suction device and transported, in particular by means of negative pressure, through a transport line of the suction device to a target position.

[0037] During its transport to the target position, the bristle bundle can be rotated around its longitudinal axis by a defined angle to align the bristle bundle. The angle can be determined by torsion of an internal transport lumen of the transport line.

[0038] The invention is described in more detail below using an exemplary embodiment, but is not limited to this exemplary embodiment. Further exemplary embodiments result from combining the features of individual or multiple claims with one another and / or by combining individual or multiple features of the exemplary embodiment. Figure 1 shows a perspective view of a bundle separating device which, as a bundle separator, has a rotatably driven separating disc with multiple separating notches and a bundle forming device which is designed to reshape the bristle bundles located in the separating notches, wherein the bundle forming device and its forming tools are shown in an open position,

[0039] Figure 2 shows the detail marked with the circle in Figure 1 in an enlarged view, where the bristle bundles can be seen in the compartment notches between the forming tools of the bundle forming device,

[0040] Figures 3 and 4 show the bundle separating device shown in Figures 1 and 2 with the forming tools of the bundle forming device brought closer together,

[0041] Figures 5 and 6 show the bundle separating device shown in the previous figures with closed forming tools of the bundle forming device and bristle bundles arranged therebetween and held in a deformed manner in the separating notches,

[0042] Figures 7 and 8 show the bundle separating device shown in the previous figures, wherein the bristle bundles are pushed out of the separating notches of the bundle separator from their positions shown in the two figures by a corresponding removal movement, which is carried out with the forming tools of the bundle forming device transversely to the rotation axis of the bundle separator, with the additional action of a pressing device arranged below the bundle separator, so that the bundle separator can be rotated further to separate further bristle bundles,

[0043] Figures 9 and 10 show the bundle separating device shown in the previous figures, wherein a heating element of a melting station of the bundle separating device for melting fastening-side bundle ends is shown positioned in its use position on the forming tools of the bundle forming device, and wherein the forming tools here function as a heat shield with which the elements located beyond the forming tools, in particular the bundle separator and non-melting sections of the bristle bundles, are shielded from the heat effect of the heating element and are thereby protected,

[0044] Figures 11 and 12 show the bundle separating device shown in the previous figures, wherein the two forming tools of the bundle forming device with the bristle bundles arranged therebetween are arranged in a transfer position at a distance from the bundle separator on a suction device in order to suck out the bristle bundles fused on the fastening side by means of negative pressure and transport them to a target position,

[0045] Figures 13 and 14 show the bundle separating device shown in the previous figures with the transport lines of the suction device in the suction position, so that the mouth openings of the transport lines are placed over the fused fastening-side ends of the bristle bundles to be transported away and located between the forming tools, with the forming tools of the bundle forming device still clamping the bristle bundles,

[0046] Figures 15 and 16 show the bundle separating device shown in the previous figures with slightly opened forming tools, so that the bristle bundles arranged between the forming tools can be sucked off by means of the suction device, and

[0047] Figures 17 and 18 show the bundle separating device shown in Figures 15 and 16, whereby the bristle bundles have already been sucked out of the forming tools.

[0048] All figures show a bundle separating device, designated as a whole by 1, which is part of a bristle goods manufacturing machine, designated as a whole by 100.

[0049] The bundle separating device 1 serves to separate bristle bundles 2 from a supply 3 of loose bristle filaments 4 and for this purpose has a bundle separator 5. The bundle separator 5 is in the illustrated embodiment of the bundle separating device 1 as a rotatably driven

[0050] Dividing disc which can be moved about a rotation axis between a bristle magazine 23 of the bundle dividing device 1 with the supply 3 of loose bristle filaments 4 and a removal position.

[0051] The bundle separator 5 has a plurality of separating notches 6 formed on the edge of the bundle separator 5. The bundle separating device 1 has a bundle forming device 7 which is arranged on the bundle separator 5 in the removal position and is designed to reshape the bristle bundles 2 located in the separating notches 5, in particular while the bristle bundles 2 are still arranged in the separating notches 5.

[0052] For this purpose, the bundle forming device 7 has two mutually assigned and correspondingly designed forming tools 8 and 9, with which the bristle bundles 2 located in the separating notches 6 can be formed by acting on their fastening-side sections. The forming tools 8 and 9 can be moved in a forming movement relative to the bundle separator 5 and also relative to one another. In the embodiment of the bundle separating device 1 shown in the figures, the upper forming tool, designated 8, is brought closer to the lower forming tool, designated 9, for forming the bristle bundles 2.

[0053] The forming tools 8 and 9 each have a forming area 10 for each separation notch 6 of the bundle separator 5. With the help of the forming areas 10 of the forming tools 8 and 9, the bristle bundles 2 located in the separation notches 6 can be formed. The lower forming tool 9 of the two forming tools 8 and 9 also has a guide surface 11 for the upper forming tool 8 assigned to it. Along the guide surface 11, the upper forming tool 8 can be moved in a targeted manner into its forming position on the lower forming tool 9. The forming movement carried out with the forming tools 8 and 9 takes place transversely, namely at right angles to a rotation axis of the bundle separator 5. The two forming tools

[0054] 8 and 9 are arranged in planes above the plane of movement of the bundle separator 5 .

[0055] The lower forming tool 9 has projections 13 on its upper flat side 12 at the edge of the guide surface 11, which serve to support the bristle bundles 2 located in the forming areas 10 of the forming tool 9. Each forming area 10 of the forming tool 9 is assigned such a projection 13.

[0056] With its shaping tools 8 and 9, the bundle shaping device is designed to shape the bundles 2 to be shaped in a fastening-side bundle section 14 that projects upwards from the respective separation notch 6 of the bundle divider 5. The shaping tools 8 and 9 are also designed as clamps. This means that the shaping tools 8 and 9 can not only shape the bristle bundles 2, but also hold them. The bundle divider 5 can thus be rotated further to separate additional bristle bundles 2 as soon as the shaping tools 8 and 9 clamp the bristle bundles 2.

[0057] The bundle forming device 7 is formed by the forming tools 8 and

[0058] 9 is further configured to remove the bristle bundles 2 located in the dividing notches 6. For this purpose, the shaping tools 8 and 9 can perform a removal movement, which is caused by a linear drive 22 and takes place relative to the bundle divider 5 and is oriented transversely to the rotation axis of the bundle divider 5. The removal of the bristle bundles 2 by means of the shaping tools 8 and 9 from the dividing notches 6 of the bundle divider 5 becomes clear by comparing Figures 5-14.

[0059] The figures further show that the bundle separating device 1 has a melting station 15 with a heating element 16 for melting fastening-side ends 17 of bristle bundles 2. Figures 9 and 10 show the use of the melting station 15 and its heating element 16. The heating element 16 can be moved from the starting position shown in Figures 1-8 into the use position shown in Figures 9 and 10. For this purpose, the melting station 15 has a guide 18 along which the heating element 16 can be displaced between the starting position and the use position. While the heating element 16 is arranged in the use position, the two forming tools 8 and 9 serve as a heat shield which shields the bundle separator 5 and non-melting sections of the bristle bundles 2, which are arranged behind the forming tools 8 and 9, from the heating element 16 of the melting station 15.

[0060] The bundle separating device 1 further comprises a pressing device 19 designed to press bristle bundles 2 out of the separating notches 6 of the bundle separator 5. The pressing device 19 is arranged below the bundle separator 5, which is designed as a separating disc.

[0061] The bundle separating device 1 further comprises a suction device 20 which is set up to suction and transport bristle bundles 2 from the bundle forming device 7 into a target position. The suction device 20 has a number of transport lines 21 which corresponds to the number of separating notches 6. The transport lines 21 are connected to a vacuum source (not shown in detail) which enables the bristle bundles 2 to be transported away through the transport lines 21 by means of vacuum. The transport lines 21 can be moved from an initial position into a suction position on the bundle forming device 7. The transport lines 21 are shown in their initial position, for example, in Figures 1-10 and assume their suction position on the bundle forming device 7 and its forming tools 8 and 9 in Figures 13-18.

[0062] At least one of the transport lines 20 can be configured to rotate bristle bundles 2 on their way to the target position by a defined angular amount about their longitudinal axis and thereby bring them into a defined target orientation.

[0063] For this purpose, at least one of the transport lines 21 can have an inner transport lumen which is twisted by a defined angular amount in its course to the target position.

[0064] The transport lines 21 furthermore each have internal cross-sections which correspond to the cross-section of the respective, formed bristle bundle 2 which is to be sucked out of the bundle forming device 7 via the respective transport line 21.

[0065] The bundle separating device 1 shown in the figures is designed to carry out the following method for separating and forming bristle bundles 2. The bundle separator 5 with its separating notches 6 is moved in a separating movement past the bristle magazine 23 with the supply 3 of loose bristle filaments 4 located therein. Bristle filaments 4 thereby enter the separating notches 6 and form bristle bundles 2 there. The bristle bundles 2 located in the separating notches 6 are then formed into a target cross-sectional shape by the bundle forming device 7.

[0066] The bristle bundles 2 can be reshaped while still arranged in the separating notches 6. The bundle forming device 7 reshapes the bristle bundles 2 by acting on the fastening-side bundle sections 14 of the bristle bundles 2, which protrude from the separating notches 6 transversely to a plane of movement of the bundle separator 5 and thus in the direction of the rotation axis of the bundle separator 5.

[0067] The bristle bundles 2 are then removed from the dividing notches 6 by the bundle-forming device 7. The fastening-side ends 17 of the bristle bundles 2 are fused with the previously explained heating element 16 of the melting station 15 of the bundle-dividing device 1. This fixes the cross-sectional shape of the bristle bundles 2 predetermined by the bundle-forming device 7, and the bristle filaments 4 contained in the bristle bundle 2 are interconnected.

[0068] When the fastening-side ends 17 of the bristle bundles 2 are fused, the forming tools 8 and 9 act as heat shields. When the fastening-side ends 17 of the bristle bundles 2 are fused, the forming tools 8 and 9 of the bundle forming device 7 hold the bristle bundles 2 firmly and are also arranged between the heating element 16 of the melting station 15 and the bundle separator 5. As a result, the forming tools 8 and 9 shield the elements arranged below the forming tools 8 and 9, for example the bundle separator 5 and also the sections of the bristle bundles 2 that are not to be melted, from the heating element 16 of the melting station 15. After melting the fastening-side ends 17 of the bristle bundles 2, the heating element 16 of the melting station 15 is moved back along the guide 18 to its starting position.

[0069] After the fastening-side ends 17 have been melted, the bristle bundles 2 are removed from the bundle forming device 7 using the previously mentioned suction device 20 and transported by means of negative pressure through transport lines 21 of the suction device 20 to their respective target position at a downstream processing station, not shown in the figures, of the bristle manufacturing machine 100. If necessary, the bristle bundles 2 can be rotated by a defined angular amount about their longitudinal axis during their transport to the target position in order to align the bristle bundles 2. The angular amount by which the bristle bundles 2 are rotated can be predetermined by a torsion of an inner transport lumen of the transport lines 21.
