Description

Technical Field

[0001] This utility model relates to a separating device for separating bristle bundles from a stock of loose bristle filaments, wherein the separating device comprises: a material box for containing the stock of loose bristle filaments; a bundle splitter having at least one separating notch; and at least one mating member, wherein the bundle splitter having at least one separating notch is movable through a separating area at the material box to separate the bristle bundles, and wherein the at least one separating notch is movable along the mating member to a bundle delivery position as the bundle splitter moves.

[0002] Furthermore, this utility model also relates to a brush making machine having such a separating device. Background Technology

[0003] Different implementations of the above-mentioned type of separator and brush making machine are known in the prior art.

[0004] For example, DE 10 2016 011 337 A1 discloses a separating device for a brush making machine, wherein the separating device includes a bundle splitter movable relative to a material bin and a mating member fixed relative to the movable bundle splitter. In its use state, the bundle splitter has at least one separating notch on its front side facing the material bin and a reserve of loose brush bristles stored in the bin, and the bundle splitter can move past the reserve material through the at least one separating notch to separate the bristle bundles from the reserve material, and the bundle splitter is guided along the mating member to transfer the bristle bundles to a bundle delivery position.

[0005] The beam splitter notch has two opposing blades oriented transversely to the direction of movement of the beam splitter and defining the opening of the notch. The mating parts of the beam splitter known from DE 10 2016 011 337 A1 are provided with splitting blades facing the beam splitter.

[0006] Therefore, in order to separate the bristle bundles from the material box, in previously known devices, the bundle splitter, together with at least one of its separating notches, moves through a separating region at the material box filled with bristle filaments. The separating notches are filled with bristle filaments by applying pressure to the filaments within the material box. The bristle filaments located in the separating notches collectively constitute the bristle bundle.

[0007] Once the dividing notch filled with bristles leaves the dividing area in front of the material bin, the dividing notch reaches the front of the mating member and is closed by the mating member, thus securing the bristle bundles arranged in the dividing notch along their path to the bundle delivery position. The bristle bundles are then conveyed along the mating member to subsequent processing steps by means of a bundle splitter. Therefore, it can be specified that the bristle bundles are supplied to the bristle-planting tool (Stopfwerkzeug) of the brush-making machine and anchored in the brush body by means of this tool along with a fastening anchor.

[0008] In another type of brush manufacturing, the bristle bundles are supplied to a tool via a bundle splitter, which places the bristle bundles in a defined manner into a box or other container. Alternatively, a suction device can be used to remove the bristle bundles arranged in the dividing notches and send them into a box or other holder. This method is often used in conjunction with so-called anchorless brush manufacturing.

[0009] If it is necessary to process particularly fine brush bristles, such as those with a diameter of less than 0.1 mm, existing bristle separation devices may reach their limits.

[0010] Previously known separating devices are capable of reliably handling relatively fine brush filaments with a diameter of at least about 0.1 mm. When processing brush filaments with a diameter less than 0.1 mm (=4 mils), in prior art separating devices, particularly fine brush filaments may enter the gap between the splitter and the mating member.

[0011] In existing separation devices, a gap exists between the splitter and the mating member to avoid friction between them. Although the separation device has high adjustment precision, during operation, due to tolerances and / or vibrations, this gap can become large enough to allow bristles with a diameter less than 4 mils (i.e., less than 0.1 mm) to enter the gap. The following will be based on... Figures 3 to 11 as well as Figures 12 to 20 These problems with previously known separation devices will be explained in more detail.

[0012] Once the gap size is on the order of half the diameter of a filament, the risk of bristles being damaged during the separation process and / or getting between the splitter and the mating parts increases. This can lead to serious contamination of the separation device, thus affecting brush manufacturing. Utility Model Content

[0013] Therefore, the purpose of this invention is to provide a separating device and a brush-making machine for separating bristle bundles, which can also reliably separate bristle bundles from particularly fine bristle filaments.

[0014] To achieve this objective, a separating device for separating bristle bundles from a stock of loose bristles has been proposed, the separating device having the features described below. Therefore, to solve this problem, a separating device is proposed comprising a material bin for containing a stock of loose bristles, a bundle splitter with at least one separating notch, and at least one mating member. The bundle splitter can move along with the at least one separating notch through a separating area at the material bin to separate the bristle bundles. The at least one separating notch can move along the mating member with the bundle splitter to a bundle delivery position. According to this invention, the bundle splitter has a contour structure on its front side facing the mating member, through which the bundle splitter and the mating member are overlapped when the separating notch is located at the mating member.

[0015] By forming a contour structure on the beam splitter (through which the beam splitter and the mating member are overlapped in a wrapping manner), a straight gap that allows brush filaments to enter between the mating member and the beam splitter is avoided. Then, through the wrapping overlap between the beam splitter and the mating member, when the dividing notch of the beam splitter is arranged at the mating member, the mating member can at least engage with the contour structure of the beam splitter, so that the direction of the gap between the mating member and the beam splitter is not straight, but corresponds to the geometry of the contour structure, which prevents unbent brush filaments from entering.

[0016] Therefore, the separating device according to this invention can reliably separate bristle bundles from a stock of loose bristle filaments with a relatively small diameter (e.g., less than 0.1 mm). This makes it possible to reliably manufacture brushes with bristle packings made of correspondingly fine bristle filaments.

[0017] As previously mentioned, when the separating notch is located at the mating part, the mating part can be engaged into the profile structure of the beam splitter.

[0018] Particularly preferably, the contour structure is formed near at least one dividing notch. This ensures that, in at least one dividing notch region, the gap between the splitter and one or more mating members has a geometry that prevents accidental entry of brush bristles.

[0019] In embodiments of the separating device, a contour structure is defined on both sides of at least one separating notch in the direction of movement of the splitter. A splitter having such a contour structure on both sides of at least one separating notch is suitable for separating bristle bundles from a stock of loose bristle filaments, wherein the splitter is guided multiple times, if necessary, through the separating area at the material bin in an alternating motion, and in this case, mating members present on both sides of the separating area mate with at least one separating notch.

[0020] In order for the beam splitter to move alternately in front of the material box and its partitioning area, it is advantageous for the partitioning device to have a mating member on each side of the partitioning area relative to the direction of movement of the beam splitter through the partitioning area of ​​the material box. Thus, when the partitioning notch of the beam splitter is arranged at the corresponding mating member, the mating member can overlap with the contour structure of the beam splitter.

[0021] In this way, the correspondingly fine brush bristles are prevented from entering the gap between the mating parts on both sides of the separation area at the splitter and the material box.

[0022] In a preferred embodiment of the separating device, the contour structure has at least two contour structure protrusions spaced apart from each other transversely to the direction of movement of the splitter. The splitter overlaps with the mating members on opposite sides of the mating members through these contour structure protrusions. Thus, the gap between the mating members and the splitter has a cross-section that differs from a rectangular cross-section and effectively prevents accidental entry of bristles. Consequently, when the gap is observed along the length of the bristles located in the separating notch, no straight, continuous gap appears.

[0023] The contour structure can have contour structure grooves, specifically between two contour structure protrusions spaced apart from each other in a direction transverse to the direction of movement of the beam splitter. When the separating notch is located at the mating member, the mating member is arranged in these contour structure grooves. Such contour structure grooves on the front side of the beam splitter facing the mating member allow for particularly large-area wrapping overlap of the mating member on two different sides, thereby forming a gap with, for example, a C-shaped or V-shaped cross-section between the beam splitter and the mating member. This reliably prevents brush bristles from entering the gap formed between the mating member and the beam splitter.

[0024] At least one dividing notch may be formed within the contour structure groove of the beam splitter's contour structure. At least one dividing notch may extend through the bottom of the contour structure groove.

[0025] In a preferred embodiment of the separating device, the profile structure of the splitter has at least one bevel that connects the profile structure end face to at least one separating notch. Along the at least one bevel, bristles that have left the material bin but have not reached the separating notch can be pushed back into the material bin by the movement of the splitter relative to the mating member. For example, the at least one bevel of the profile structure can be a flat bevel, particularly a chamfer, and / or particularly a curved bevel around a radius.

[0026] In this context, it may be advantageous if at least one mating member has a counter-sloping surface along which bristles that have not entered the separator recess of the bundle splitter can be pushed back into the material bin. For example, the counter-sloping surface can be a flat counter-sloping surface or, in particular, a counter-sloping surface that is curved around a radius.

[0027] The contour structure, particularly the contour structure groove, can be formed on the entire section of the front side of the beam splitter, passing through the mating member. Within the contour structure, especially within the contour structure groove, multiple dividing notches can be formed. These dividing notches are movable through the dividing area to accommodate brush filaments from the beam splitter's material box. The multiple dividing notches can be arranged at intervals between each other on the front side of the beam splitter in the direction of movement of the beam splitter.

[0028] For example, the profile structure groove of the beam splitter can have a V-shaped cross-section. If the splitting notch of the beam splitter is arranged at the mating member, the mating member can be arranged within the V-shaped cross-section.

[0029] The mating member may have a protrusion on its side facing the beam splitter, preferably a protrusion with a V-shaped cross section, through which the mating member engages with the contour structure of the beam splitter, preferably with the contour structure groove.

[0030] Therefore, the geometry of the mating member can be matched with the geometry of the contour structure on the front side of the beam splitter facing the mating member. This facilitates the formation of a gap between the mating member and the beam splitter, which has a geometry that effectively prevents brush filaments from entering the gap between the mating member and the beam splitter.

[0031] In the case of correspondingly formed contoured grooves and correspondingly formed mating parts, the gap formed between the splitter and the mating parts can have, for example, a V-shaped cross-section. This gap is not easily accessible to unbent bristles that do not enter the separating notch when separating the bristle bundles.

[0032] To avoid damaging the bristles when separating them, it may be advantageous if the splitter has at least one blade oriented transversely to the direction of movement of the splitter, which is rounded in a direction transverse to its length extension direction, for example, with a rounding radius of 0.003 mm to 0.03 mm.

[0033] In order to separate the bristles particularly gently from the material bin of the separating device, it may be reasonable if at least one mating member has at least one dividing blade oriented transversely to the direction of movement of the splitter, which is rounded in a direction transverse to its length extension direction, for example, with a rounding radius of 0.003 mm to 0.03 mm.

[0034] The bundle splitter may have two blades oriented transversely to the direction of movement of the bundle splitter, which define the opening of the separating notch. In this case, both blades can be rounded in the manner described above. It is particularly advantageous if the rear blade (which defines the separating notch of the bundle splitter) located at the aforementioned bundle delivery position in the direction of bristle bundle transport is correspondingly rounded.

[0035] There is a high risk associated with this type of blade: bristles that do not fully enter the separating notch during separation from the material bin can become trapped between the blade of the splitter and the dividing edge of the mating component, and be damaged by these edges. The risk of bristle damage can be reduced by using a rounded design for the blade and the preferred dividing edge.

[0036] To ensure trouble-free separation of bristle bundles from the material bin, it may be more advantageous if at least one surface of the bundle splitter facing the mating member is polished. For example, the average roughness value or surface roughness value Ra of the at least one surface may be less than 0.1, preferably less than 0.05, and particularly preferably less than 0.02.

[0037] The mating parts may also have a surface facing the beam splitter and being polished. For example, the average surface roughness value or surface roughness value Ra may be less than 0.1, preferably less than 0.05, and particularly preferably less than 0.02.

[0038] In embodiments of the separating device, the splitter and / or at least one mating member has at least one fastening interface for securing the assembly fixture (Montagelehre). The assembly fixture may be at least temporarily part of the separating device.

[0039] For example, the splitter and / or mating member may each have at least one hole as a fastening interface, by means of which the assembly fixture can be temporarily fixed for adjusting the spacing between the splitter and mating member of the separating device. This can significantly simplify the commissioning process of the separating device used to separate bristle bundles.

[0040] Depending on the application, the beam splitter can be designed as an arc-shaped divider, a dividing slider, or a dividing disk.

[0041] If the bundle splitter is designed as an arc-shaped divider, the arc-shaped divider can, for example, pivot back and forth about a pivot in an alternating motion between the dividing area at the material box and the bundle delivery position.

[0042] If the bundle splitter is designed as a separating slider, the separating slider can move in a linear motion past the material bin to separate the bristle bundles, and can move to the bundle delivery position to deliver the bristle bundles.

[0043] In another embodiment of the separating device, the separating device has a divider designed as a dividing disk. The dividing disk can realize the separating movement in the form of alternating pivoting or rotational movement. Whether it is an arc-shaped divider, a dividing slider, or a dividing disk, it can be designed with more than one dividing notch.

[0044] To achieve this objective, a brush-making machine has been proposed, which includes the aforementioned separating device for separating bristle bundles. In an embodiment of the brush-making machine (which allows bristle bundles to be implanted into a prepared bristle carrier to manufacture a brush), the brush-making machine is specified to have at least one bristle-planting tool. The bristle-planting tool can be configured to implant bristle bundles, transferred from a bristle separator using the separating device, into the prepared bristle carrier.

[0045] The brush-making machine may also have a clamping device for clamping at least one bristle carrier to be fitted with bristle bundles. Using the clamping device, at least one bristle carrier can be clamped in the processing position, particularly at the bristle-planting tool of the brush-making machine, as mentioned earlier.

[0046] In one embodiment of the brush-making machine, wherein the separated bristle bundles are conveyed to a downstream processing station of the brush-making machine via a fluid flow (e.g., airflow or airflow), the brush-making machine may be provided with a suction device. The suction device is configured to convey the bristle bundles separated by the separating device to the downstream processing station of the brush-making machine by means of negative pressure.

[0047] For example, the suction device may include at least one negative pressure source and / or at least one delivery line through which the bristle bundle can be drawn out and delivered from the dividing notch of the bundle distributor located at the bundle delivery position by means of negative pressure.

[0073] Figure 1 and Figure 2 as well as Figures 21-62 At least a portion of a separating device, generally labeled 1, is shown. This separating device is used to separate bristle bundles from a stockpile of loose bristle filaments 3.

[0074] The separating device 1 includes a material box 4 for holding a reserve material 2 of loose brush bristles 3, a splitter 5 having at least one separating notch 6 on its front side 11, and at least one mating member 7.

[0075] The bristle splitter 5 can move through the dividing area 8 at the material bin 4, carrying at least one dividing notch 6, to separate the bristle bundles from the stock material 2 in the material bin 4. Then, the at least one dividing notch 6, along with the bristle bundles located therein, can move along the mating member 7 with the bristle splitter 5 to the bundle delivery position. Figure 1 and Figure 2 as well as Figure 25 and Figure 26 The location of the bundle delivery is shown and is marked as 33.

[0076] Then, at the corresponding bundle delivery position 33, the separated bristle bundles can be transferred to downstream tools or downstream processing steps.

[0077] exist Figure 1 and Figure 2 In the case of the dividing device 1 shown, the bristle bundle is transferred by means of the bristle splitter 5 to the bristle planting tool 9 of the brush making machine, which is generally marked as 10, and the dividing device 1 is arranged on the brush making machine.

[0078] In order to separate the bristle bundles from the particularly fine bristle filaments 3, the bristle splitter 5 according to the present invention has a contour structure 12 at the position of its front side 11 facing the corresponding mating member 7 near the separating notch 6. When the separating notch 6 is located at the mating member 7, the contour structure 12 causes the corresponding bristle splitter 5 to overlap the mating member 7 in a wrapping manner.

[0079] By overlapping the mating member 7 in this way, a gap 28 is formed between the splitter 5 and the mating member 7. The shape of the gap 28 can also effectively prevent relatively fine bristles 3 from entering the gap 28.

[0080] Figures 3-11 as well as Figures 12-20 A beam splitter 5 is shown at the mating member 7 of the prior art separating device 1.

[0081] These figures show that the beam splitter 5 has no comparable profile structure 12 on its front side 11 facing the mating member 7, and the mating member 7 does not overlap when the separating notch 6 is located at the mating member 7. Therefore, a gap still exists between the beam splitter 5 and the mating member 7.

[0082] Figures 3-11 The diagram shows bristle bundles separated from bristle filaments 3, which have, for example, a diameter of 0.1 mm or greater.

[0083] according to Figure 6 and Figure 7 When assembling the beam splitter 5 and the mating member 7, the distance between the beam splitter 5 and the mating member 7 is first adjusted to about 0.04 mm. During the operation of the separating device 1, the movement of the beam splitter 5 relative to the mating member 7 when splitting the bristle bundles may cause vibration, which may also cause the distance between the beam splitter 5 and the mating member 7 to change.

[0084] This is Figure 9 and Figure 11 As shown in the image. Figure 9 The maximum spacing between the beam splitter 5 and the mating member 7, as expected based on experience, is shown here to be approximately 0.08 mm. Figure 9 The bristle 3 shown in the diagram has a diameter of about 0.1 mm, so even when the maximum gap occurs between the splitter 5 and the mating member 7, the risk of the bristle 3 entering the gap 28 is still very small.

[0085] Figure 11The minimum possible spacing between the beam splitter 5 and the mating member 7 is shown. This minimum spacing can be adjusted during the operation of the separating device 1 and is, for example, 0.005 mm.

[0086] Figures 12-20 It shows Figures 3-11 The separating device 1 separates the bristle bundles from the finer bristle filaments 3, which have a diameter of less than 0.1 mm, for example 0.077 mm (=3 mils). Figure 18 The maximum spacing is shown when the beam splitter 5 and the mating member 7 are present.

[0087] It is clearly visible that the spacing is large enough that relatively fine bristle filaments 3 may enter the gap 28 between the mating member 7 and the splitter 5. If bristle filaments 3 are pulled into the gap 28 between the splitter 5 and the mating member 7, this may cause serious contamination of the separating device 1 and its equipped brush making machine 10, which may ultimately lead to quality damage during the brush production process and shutdown of the separating device 1.

[0088] The separating device 1 shown in the other figures effectively avoids the formation of a gap 28 between the respective splitter 5 and the respective mating member 7, where fine bristles 3 can enter, having a diameter of, for example, less than 0.1 mm (e.g., 0.077 mm), due to the design of its splitter 5 and mating member 7.

[0089] exist Figure 21 , Figure 22 , Figure 23 , Figure 24 , Figure 27 , Figure 28 , Figure 31 , Figure 32 and Figures 33-54 In the embodiment of the separating device 1 shown, when the separating notch 6 is located at the corresponding mating member 7, the mating member 7 engages with the contour structure 12 of the beam splitter 5 associated with the mating member 7.

[0090] exist Figures 21-46 and Figures 50-54 In the embodiment of the beam splitter 5 shown, the corresponding contour structure 12 has two contour structure protrusions 13 and 14, which are spaced apart from each other in a direction transverse to the direction of movement of the beam splitter 5. Through these two contour structure protrusions 13 and 14, the corresponding beam splitter 5 and its associated mating member 7 are overlapped at the two opposite sides of the mating member 7.

[0091] exist Figures 47 to 49The beam splitter 5 shown has a contour structure 12 including a single contour structure protrusion 13. When the separating notch 6 is guided past the mating member 7, the beam splitter 5 overlaps with the mating member 7 through the contour structure protrusion 13.

[0092] The contour structure 12 is formed on both sides of the corresponding dividing notch 6 of the beam splitter 5 in the direction of movement of the beam splitter 5. The contour structure 12, having two contour structure protrusions 13 and 14 spaced apart from each other, includes a contour structure groove 15 in which the corresponding mating member 7 is arranged when the dividing notch 6 is located at the mating member 7.

[0093] Figure 24 , Figure 28 , Figure 32 , Figures 33-41 , Figures 42-46 and Figures 50-54 The diagram shows that the dividing notch 6 is formed within the contour structure groove 15 of the corresponding beam splitter 5.

[0094] The contour structure 12 has bevels 16 and 17 that connect the contour structure end face 18 of the contour structure 12 to the corresponding dividing notch 6. These bevels 16 and 17 can be designed as flat bevels with chamfers 19, or as... Figures 50-54 In the embodiment of the beam splitter 5 shown, it can be designed as a bend 20 curved around the radius.

[0095] During the separation process, the bristles 3 can enter the corresponding separation recess 6 from the reserve material 2 of loose bristles 3 arranged in the material box 4 of the corresponding separation device 1 along the inclined surfaces 16 and 17. When the bundle splitter 5 moves past the mating member 7, the bristles 3 that have not entered the separation recess 6 can be pushed back into the material box 4 along the mating member 7.

[0096] For example, in Figure 22 , Figure 24 , Figure 28 , Figure 32 , Figure 33 , Figure 37 , Figure 39 , Figure 41 , Figures 45 to 47 You can see flat bevels 16 and 17 in the form of chamfer 19.

[0097] exist Figure 22 , Figure 24 , Figure 28 , Figure 32 , Figure 33 , Figure 37 , Figure 39 , Figure 41 , Figures 45 to 47It can also be seen that the bevels 16 and 17 are formed on the contour structure protrusions 13 and 14 of the corresponding contour structure 12, and thus are formed on both sides of the separating notch and on both sides of the contour structure groove 15 (if present). According to the figure, the mating piece 7 also has a bevel 21 on its side facing the material box 4, in particular a bevel in the form of a chamfer, i.e. a flat bevel and / or a bevel curved around the radius.

[0098] The contour structure 12 (especially the contour structure groove 15) is formed on the entire section of the front side 11 of the corresponding beam splitter 5, passing through the mating member 7.

[0099] The contour structure groove 15 of the beam splitter 5 shown in the figure has a V-shaped cross-section. The mating member 7 has a corresponding V-shaped cross-section protrusion 22 on its side facing the corresponding beam splitter 5. The corresponding mating member 7 is engaged into the contour structure 12 through its protrusion 22, that is, into the contour structure groove 15 of the beam splitter 5 associated with it.

[0100] The beam splitter 5 shown in the figure has a blade 23 oriented transversely to the direction of movement of the beam splitter 5.

[0101] exist Figure 23 and Figure 24 as well as Figures 42-46 In the embodiment of the beam splitter 5 shown, the blade 23 (which also defines the dividing notch 6 of the beam splitter 5) is rounded in a direction transverse to its length extension direction, for example, with a rounding radius of 0.003 mm to 0.03 mm.

[0102] The mating member 7 has a dividing blade 24 oriented transversely to the direction of motion of its associated beam splitter 5. Figure 23 and Figure 24 as well as Figures 42-46 In the embodiment of the mating member 7 shown, the rounding radius of the dividing blade 24 is, for example, 0.003 mm to 0.03 mm.

[0103] The rounded shape of the blade 23 and the dividing blade 24 helps to separate the bristle bundles particularly gently from the bristle filaments 3, because the rounding reduces the risk of damage to the bristle filaments 3.

[0104] The beam splitter 5 and the mating member 7 have surfaces facing each other, which are polished. For example, the average roughness value or surface roughness value Ra of these surfaces may be less than 0.1, preferably less than 0.05, and particularly preferably less than 0.02.

[0105] according to Figure 1 and Figure 2 , Figure 21 , Figure 23 , Figure 25 , Figure 26 , Figure 27 and Figures 29-31 The beam splitter 5 and mating member 7 shown have fastening interfaces 25 for securing the assembly fixture 26. Holes serve as fastening interfaces 25.

[0106] Assembly fixture 26 is used to set the spacing between the beam splitter 5 and the associated mating part 7 when assembling the beam splitter 5 and the associated mating part 7.

[0107] Figures 55-58 Different single-component diagrams of a first embodiment of this assembly fixture 26 are shown, which can be used, for example, for... Figure 1 and 2 as well as Figure 25 and Figure 26 The separating device 1 shown.

[0108] Figures 55-58 The assembly fixture 26 shown includes four pins 27, which can be inserted into fastening interfaces 25 on the respective splitter 5 and mating member 7 of the dividing device 1 to fix the assembly fixture 26 and set the required spacing between the splitter 5 and the mating member 7.

[0109] For example, Figures 59-62 The assembly fixture 26 shown can be used for adjustment Figures 29-30 The spacing between the beam splitter 5 and the mating member 7 of the separating device 1 shown.

[0110] Figures 59-62 The assembly fixture 26 shown also has four pins 27, which are arranged to... Figure 29 and Figure 30 The splitter 5 of the separating device 1 shown is adapted to the fastening interface 25 on the mating part 7.

[0111] The various figures partially illustrate different embodiments of the beam splitter 5. Figure 1 and Figure 2 as well as Figures 21-34 The splitter 5 shown is a so-called arc-shaped divider that can move along a circular track in an alternating pivoting motion in order to grab bristle bundles from the stock 2 of loose bristle filaments 3.

[0112] Figure 25 and Figure 26 The shown separating device 1 has a splitter 5 designed as a separating disk. The separating disk has a closed, surrounding circumferential surface on which a plurality of separating notches 6 are formed. The circumferential surface is substantially cylindrical, therefore this separating disk can also be referred to as a disc.

[0113] Figures 29-32The splitter 5 shown is designed as a separating slider. The separating slider has multiple (five in total) separating notches 6 on its flat front side 11 facing the material bin 4 of the separating device 1. The separating notches 6 move in alternating linear motion (see...). Figure 29 The double-headed arrow in the middle moves through Figure 29 and Figure 30 The separating area 8 at the material box 4 of the separating device 1 shown is used to separate the bristle bundles from the stock material 2 of loose bristle filaments 3.

[0114] Figure 1 and Figure 2 A brush-making machine, generally designated 10, is shown, equipped with a separating device 1 according to the present invention. The brush-making machine 10 has a bristle-planting tool 9 for inserting bristle bundles transferred to the bristle-planting tool 9 by means of a bristle splitter 5 using the separating device 1. By means of the bristle-planting tool 9, the bristle bundles can be inserted into a prepared bristle carrier 29 and thus secured to the bristle carrier 29.

[0115] To secure the bristle carrier 29, the brush making machine 10 also has a clamping device 30. The bristle carrier 29 can be clamped at the clamping device 30 so that bristle bundles can be implanted into the bristle carrier 29 by means of the bristle implantation tool 9.

[0116] according to Figure 25 and Figure 26 A suction device 31 is provided on the brush making machine 10 shown therein for conveying the bristle bundles separated by the separating device 1 to the downstream processing station of the brush making machine 10 by means of negative pressure.

[0117] The suction device 31 includes a negative pressure source (not shown) and a delivery line 32, through which the suction device 31 can be used to deliver the suction device by means of negative pressure. Figure 25 and Figure 26 The bristle tuft of the dividing device 1 shown in the diagram is drawn out from the dividing notch 6 and thus conveyed out from the tuft delivery position 33.

[0118] exist Figure 1 and Figure 2 In the diagram, the bidirectional arrows are associated with the material bin 4, the bundle splitter 5, and the tufting tool 9, respectively. The bidirectional arrows on the material bin 4 indicate that the material bin 4 can pivot about a pivot axis so that the individual material compartments of the material bin 4 can be contacted by the bundle splitter 5.

[0119] The bidirectional arrow on the splitter 5 indicates that the splitter 5 can move in an alternating pivoting motion to separate the bristle bundles.

[0120] The double-headed arrows on the bristle implantation tool 9 indicate the movement performed by the bristle implantation tool 9 in implanting the bristle bundles into the prepared bristle carrier 29.

[0121] In a similar way, Figure 25 and Figure 26 as well as Figure 29 and Figure 30 The double-headed arrows in the image also symbolize the movement of these functional components.

[0122] Figure 25 and Figure 26 The bidirectional arrows on beam splitter 5 indicate the alternating motion of beam splitter 5, which is designed as a dividing disk.

[0123] Figure 29 and Figure 30 The bidirectional arrows on beam splitter 5 indicate the alternating movement of beam splitter 5, which is designed to separate sliders. Figure 29 and Figure 30 The arrow in the material box 4 indicates the direction of movement of the pusher 34 in the material box 4, so as to press the bristles 3 against the splitter 5.

[0124] Therefore, this utility model relates to a separating device 1 for separating bristle bundles from a stock of loose bristle filaments 3. The separating device 1 has a material box 4 for receiving the stock of loose bristle filaments 3, a bristle splitter 5 with at least one separating notch 6, and at least one mating member 7. The bristle splitter 5 is configured to move through a separating region 8 at the material box 4 with at least one separating notch 6 to separate the bristle bundles. The at least one separating notch 6 can move along the mating member 7 with the bristle splitter 5 to a bundle delivery position. The bristle splitter 5 has a contour structure 12 on its front side 11 facing the mating member 7, through which the bristle splitter 5 overlaps the mating member 7 in a wrapping manner when the separating notch 6 is located at the mating member 7.
