DETAILED DESCRIPTION
[0074]
[0075] The separating devices 1 each comprise a material box 4 for receiving the store 2 of loose bristle filaments 3, a bundle separator 5 having at least one separating notch 6 on its front side 11, and at least one counter piece 7.
[0076] The bundle separator 5 can be moved with the at least one separating notch 6 through a separating region 8 at the material box 4, in order to separate bundles of bristles from the store 2 in the material box 4. The at least one separating notch 6 can then be moved, together with the bundle of bristles located therein, with the bundle separator 5 along the counter piece 7 into a bundle delivery position. Bundle delivery positions are shown in
[0077] In the respective bundle delivery position 33, a separated bundle of bristles can then be transferred to a downstream tool or to a downstream processing step.
[0078] In the case of the separating device 1 shown in
[0079] To separate bundles of bristles made of particularly fine bristle filaments 3, the bundle separators 5 according to the invention have, on their front side 11 facing the respective counter piece 7, next to the separating notch 6, a profile 12 with which the respective bundle separator 5 overlaps the counter piece 7 when the separating notch 6 is located at the counter piece 7.
[0080] As a result of this overlapping of the counter piece 7, a gap 28 is formed between the bundle separator 5 and the counter piece 7, with a shape that can effectively prevent the ingress even of comparatively fine bristle filaments 3 into this gap 28.
[0081]
[0082] These figures show that the bundle separator 5 does not have, on its front side 11 facing the counter piece 7, a comparable profile 12 and also does not overlap the counter piece 7 when a separating notch 6 is present at the counter piece 7. Accordingly, there is then also a gap between the bundle separator 5 and counter piece 7.
[0083]
[0084] A distance between the bundle separator 5 and the counter piece 7 is initially set to about 0.04mm during the assembly of the bundle separator 5 and of the counter piece 7 according to
[0085] This is shown in
[0086]
[0087]
[0088] It is clearly apparent that the distance is so large that the comparatively fine bristle filament 3 can pass into the gap 28 between the counter piece 7 and the bundle separator 5. If a bristle filament 3 is drawn into the gap 28 between the bundle separator 5 and the counter piece 7, this can result in considerable soiling of the separating device 1 and of the brush making machine 10 equipped therewith, and this can ultimately entail quality impairments in the production of brushes and even downtimes of the separating device 1.
[0089] On account of the design of their bundle separators 5 and counter pieces 7, the separating devices 1 shown in the remaining Figures effectively avoid the formation of a gap 28 between the respective bundle separator 5 and the respective counter piece 7, into which gap a fine bristle filament 3 can pass, which has, for example, a diameter of less than 0.1mm, for example 0.077mm.
[0090] In the exemplary embodiments of separating devices 1 shown in
[0091] In the exemplary embodiments of bundle separators 5 shown in
[0092] The bundle separator 5 shown in
[0093] The profiles 12 are formed on both sides of the respective separating notch 6 of the bundle separator 5 in the direction of movement of the bundle separator 5. The profiles 12, which have two profile protrusions 13 and 14 that are spaced apart from one another, comprise a profile groove 15 in which the respective counter piece 7 is arranged when a separating notch 6 is located at the counter piece 7.
[0094]
[0095] The profiles 12 have inclined faces 16 and 17 which connect a profile end face 18 of the profile 12 to the respective separating notch 6. These inclined faces 16 and 17 can be configured as bevels 19 in the form of planar inclined faces or, as in the exemplary embodiment of a bundle separator 5 shown in
[0096] Along the inclined faces 16 and 17, bristle filaments 3 can pass into the respective separating notch 6 during separation from the store 2 of loose bristle filaments 3, which is arranged in the material box 4 of the respective separating device 1. The bristle filaments 3 which have not passed into the separating notch 6 can, when the bundle separator 5 is moved past the counter piece 7, be pushed back along the counter piece 7 into the material box 4.
[0097] Planar inclined faces 16 and 17 in the form of bevels 19 are apparent, for example, from
[0098] It is also apparent from
[0099] The profiles 12, in particular the profiles grooves 15, are each formed over the entire portion, passing the counter piece 7, of the front side 11 of the respective bundle separator 5.
[0100] The profile grooves 15 of the bundle separators 5 shown in the figures have a V-shaped cross section. The matching counter pieces 7 have, on their side facing the respective bundle separator 5, a protrusion 22 with a correspondingly V-shaped cross section. With its protrusion 22, the respective counter piece 7 engages in the profile 12, specifically in the profile groove 15 of the bundle separator 5 associated with it.
[0101] The bundle separators 5 shown in the figures each have knife edges 23 oriented transversely to the direction of movement of the bundle separator 5.
[0102] In the exemplary embodiments of bundle separators 5 shown in
[0103] The counter pieces 7 have a parting edge 24 oriented transversely to the direction of movement of the bundle separator 5 associated with them. In the case of the embodiment of counter pieces 7 shown in
[0104] The rounded shapes of the knife edges 23 and parting edges 24 favor particularly gentle separation of bundles of bristles made of bristle filaments 3, since the rounded portions reduce the risk of the bristle filaments 3 being damaged.
[0105] The bundle separators 5 and the counter pieces 7 have mutually facing faces that are polished. These faces can have, for example, an average roughness value or surface roughness value of Ra less than 0.1, preferably of Ra less than 0.05, particularly preferably of Ra less than 0.02.
[0106] According to
[0107] The assembling jigs 26 serve to set a distance between the bundle separator 5 and counter piece 7 when assembling the bundle separator 5 and associated counter piece 7.
[0108]
[0109] The assembling jig 26 shown in
[0110] The assembling jig 26 shown in

[0112] The individual figures show partially different embodiments of bundle separators 5. The bundle separators 5 shown in
[0113] The separating device 1 shown in
[0114] The bundle separator 5 shown in
[0115]
[0116] In order to hold the bristle carriers 29, the brush making machine 10 also has a clamping device 30. A bristle carrier 29 can be clamped at the clamping device 30 in order to stuff the bristle carrier 29 with bundles of bristles with the aid of the stuffing tool 9.
[0117] According to
[0118] The suction-extraction device 31 comprises a negative pressure source (not illustrated in the figures) and transport lines 32, via which the bundles of bristles present in the separating notches 6 with the bundle separator 5 of the separating device 1 shown in
[0119] In
[0120] The double arrow at the bundle separator 5 shows that the bundle separator 5 can be moved in an alternating pivoting movement in order to separate bundles of bristles.
[0121] The double arrow at the stuffing tool 3 shows the movements that the stuffing tool 3 carries out in order to stuff bundles of bristles into a held-ready bristle carrier 29.
[0122] In a comparable way, the double arrows in

[0125] The invention thus relates to separating devices 1 for separating bundles of bristles from a store 2 of loose bristle filaments 3. The separating devices 1 have a material box 4 for receiving a store 2 of loose bristle filaments 3, a bundle separator 5 having at least one separating notch 6, and at least one counter piece 7. The bundle separator 5 is designed to be moved with the at least one separating notch 6 through a separating region 8 at the material box 4 in order to separate bundles of bristles. The at least one separating notch 6 can be moved with the bundle separator 5 along the counter piece 7 into a bundle delivery position. The bundle separator 5 has, on its front side 11 facing the counter piece 7, a profile 12 with which the bundle separator 5 overlaps the counter piece 7 when the separating notch 6 is located at the counter piece 7.
