DETAILED DESCRIPTION
[0062] In the description hereunder of different embodiments of the invention, functionally equivalent elements are provided with identical reference signs even in the case of a deviation in terms of design or shape. Unless explicitly pointed out and wherever possible, the description hereunder relates to all exemplary embodiments of the invention shown in the figures.
[0063] All of the figures show at least parts of a device, which in its entirety is identified by the reference sign 1, for compacting bristle bundles 2.
[0064] The device 1 has at least one preparation means 3, specifically a bundle separator, having bundle notches 4 and a number of compaction receptacles 5 for bristle bundles 2, said number of compaction receptacles 5 being at least identical to the number of bundle notches 4, and for each of its compaction receptacles 5 having in each case one compaction tool 6.
[0065] The compaction receptacles 5 are specified to retrieve bristle bundles 2 from the bundle notches 4 of the preparation means 3, and the compaction tool 6 are specified to compact bristle bundles 2 positioned in the compaction receptacles 5.
[0066] In all embodiments of the device 1 shown in the figures, said device 1 has a plurality of retrieval plates 7 on which the compaction receptacles 5 are distributed.
[0067] The device 1 shown in
[0068]
[0069] Each compaction receptacle 5 has in each case one introduction opening 8 for bristle bundles 2 and also for the compaction tool 6, which introduction opening 8 is aligned transversely, specifically orthogonally, to the longitudinal axis of said compaction receptacle 5 and thus orthogonally to a longitudinal axis of bristle bundles 2 disposed in the compaction receptacles 5. The compaction tools 6 are integrally connected to a holding plate 9, conjointly with the latter thus forming a materially homogenous, monolithic unit.
[0070] The compaction tools 6 are formed with sharp edges at their transitions 10 between their flanks 11 and their end side 12 facing the respective compaction receptacle 5. The sharp-edged transition is 10 between the flanks 11 and the end sides 12 of the compaction tools 6 prevent that bristle filaments 37 slip out of the compaction receptacles 5 and past the compaction tools 6, and can make their way out of the compaction receptacles 5, when compacting the bristle bundles 2.
[0071] As has already been explained in the general part of the description, the flanks 11 of the compaction tools 6 are smoothened and moreover hardened.
[0072] The compaction tools 6, in a width direction of the compaction receptacle 5 respectively assigned thereto, are in each case undersized by a measurable dimension of 0 m to 50 m, or of 0 m to 20 m, in relation to an available width of the introduction opening 8 of the respective compaction receptacle 5 measurable in the same width direction. The tolerance range between 0 m and 50 m, or 0 m and 20 m, herein depends on the filament gauge of the bristle filaments 37 of which the bristle bundles 2 consist that are to be compacted in the compaction receptacles 5.
[0073] For example,
[0074] For retrieving bristle bundles 2 from the bundle notches 4 of the respective preparation means 3, the compaction receptacles 5, conjointly with their retrieval plates 7, can be moved past the bundle notches 4 in a direction transverse, specifically orthogonal, to a longitudinal axis of the bundle notches 2, which defines the longitudinal alignment of the bristle bundles 2 positioned in said bundle notches 2. This becomes evident, for example, when comparing
[0075] The compaction of the bristle bundles 2 located in the compaction receptacles 5 takes place by a compacting movement which is performed so as to follow the retrieving movement. For example,
[0076] The compacting movement as well as the retrieving movement are linear movements of the retrieval plates 7 and of the compaction receptacles 5 formed therein, said movements being carried out relative to the preparation means 3 and to the compaction tools 6.
[0077] In the compacted state, the bristle bundles 2 are subsequently transferred from the compaction receptacles 5 into a target plate 14 of the device 1. The target plate 14 has target receptacles 15 for receiving the compacted bristle bundles 2.
[0078]
[0079] First, the target plate 14 is populated with a bristle carrier 200. Subsequently, the individual target receptacles 15 of the target plate 14 are populated with compacted bristle bundles 2. This takes place in that the compacted bristle bundles 2, with the aid of the transfer device 19 and its sliding pins 20, are pushed out of the compaction receptacles 5 of the device 1, axially out of the compaction receptacles 5 in the direction of the longitudinal axes of said bristle bundles 2, into the target receptacles 15 of the target plate 14.
[0080] According to
[0081] The target plates 14 shown in the figures are designed as cartridges and moreover serve as transport holders. In this way, the target plates 14 also serve to transport the compacted bristle bundles 2 to downstream processing stations 16 of a bristle product production machine which in its entirety is identified by the reference sign 17 and schematically illustrated in
[0082] The sectional illustration of a target plate 14 from
[0083] The retrieval plates 7 have compaction receptacles 5 which are in each case arranged in a hole pattern which corresponds at least to a hole sub-pattern of the hole arrangement of the target receptacles 15 of the target plates 14. This situation has the effect that the target plates 14 for filling all of the target receptacles 15, as is shown in
[0084] The target receptacles 15 of the target plate 14 are then successively filled with compacted bristle bundles 2, as is visualized in
[0085] All devices 1 shown in the figures also have in each case at least one transfer device 19. The transfer devices 19 serve to transfer bristle bundles 2 from the compaction receptacles 5 into the target receptacles 15 of the target plates 14.
[0086] In the process, the transfer devices 19 define a transferring direction which is aligned in the direction of the longitudinal axes of the compaction receptacles 5 and also in the direction of the longitudinal axes of the target receptacles 15 of the target plates, and thus also in the longitudinal direction of the bristle bundles 2 located in the compaction receptacles 5.
[0087] The functional mode of the transfer devices 19 will become evident by means of the illustrations of
[0088] The transfer device 19 shown in these figures has sliding pins 20 for transferring the bristle bundles 2 from the compaction receptacles 5 into the target receptacles 15 of the target plates 14. Longitudinal axes of the sliding pings 20 are aligned orthogonally to an introduction direction of the bristle bundles 2 and of the compaction tools 6 into the compaction receptacles 5.
[0089] In the devices 1 shown in the figures, the respectively used transfer devices 19 have for each retrieval plate 7 in each case one pin plate 21 on which are in each case disposed a number of sliding pins 20 that correspond to the number of compaction receptacles 5 of the respective retrieval plate 7.
[0090] The pin plates 21 have guide pins 35. The retrieval plates 9 and the target plates 14 have corresponding guide bores 36. When transferring the bristle bundles 2 from the compaction receptacles 5 into the target receptacles 15 of the target plates 14, the guide pins 35 are introduced into the guide bores 36 and in this way establish the mutual relative positions of the pin plates 21, of the retrieval plates 9 and of the target plates 14. This facilitates a precise transfer of the compacted bristle bundles 2 into the target receptacles 15 of the target plates 14.
[0091]
[0092] Furthermore, the device 1 for each retrieval plate 7 has a movable counterpart 23. The movable counterpart 23 serves to secure bristle bundles 2 which are disposed in the bundle notches 4 of the preparation means 3 against loss, until the bristle bundles 2 are retrieved from the bundle notches 4 and compacted.
[0093] The movable counterpart 23 can also be raised by a movement, or during a movement, of the retrieval plate 7 in the direction of the compaction tool 6, according to
[0094] Moreover, the devices 1 shown also have counterparts 24 which are assigned to the preparation means 3 and are designed as rigid counterparts. Rigid counterparts 24 can be readily seen in
[0095] Owing to the counterparts 23 and 24, the bristle bundles 2 located in the bundle notches 4 are secured against loss on their way from their retrieval from a supply 25 of loose bristle filaments 37 up to the compaction receptacles 5.
[0096] During the retrieving movement and the compacting movement of the compaction receptacles 5 and of the retrieval plates 7, the movable counterparts 23 are moved from an initial position to a target position. In the process, the movable counterparts 23 in the target position make their way into the receptacle space 22 of the compaction tool 6.

[0098] In the device 1 shown in
[0099]
[0100] The preparation means 3 of the device 1 shown in
[0101] Each of the devices 1 shown has a magazine 26 in which the respective supply 25 of loose bristle filaments 37 is disposed.
[0102]
[0103] The devices 1 shown in the figures are suitable for carrying out the following method for compacting bristle bundles 2.
[0104] First, bristle bundles 2 which are not yet compacted are picked from the supply 25 of loose bristle filaments 37 and provided for retrieving and compacting with the aid of the preparation means 3 of the device 1. Then, the bristle bundles 2 are first retrieved from the bundle notches 4 of the preparation means 4 and subsequently compacted to a defined degree of compaction with the aid of the compaction receptacles 5 of the respective device 1.
[0105] Depending on the degree of compaction required, the bristle bundles 2 can be compacted up to a degree of compaction of 60% to 90%, of 70% to 80%, or else of 75%.
[0106] For example,
[0107]
[0108] Similar undercuts 13 can also be seen in the compaction receptacles 5 of the two retrieval plates 7 shown in the right half of
[0109] As has already been explained above, the bristle bundles 2 upon compaction are transferred into target receptacles 15 of offered-up target plates 14 of the device 1. The transfer device 19 which is shown in the figures and has sliding pins 20 is used for this purpose. In the process, the compacted bristle bundles 2 by way of their fastening-proximal ends 202 are pushed through bundle receptacles 201 of a bristle carrier 200 by way of which the target plate 14 has previously been populated. This can be seen in
[0110]
[0111] The preparation means 3 shown in
[0112]
[0113] The invention relates to improvements in the technical field of bristle product production. Proposed to this end is, inter alia, a device 1 for compacting bristle bundles 2, wherein the device 1 has at least one preparation means 3 with bundle notches 4 and a number of compaction receptacles 5 for bristle bundles 2, corresponding at least to the number of bundle notches 4, and for each of the compaction receptacles 5 of said preparation means 4 has in each case one compaction tool 6. The compaction receptacles 5 are specified to retrieve bristle bundles 2 from the bundle notches 4 of the preparation means 3, and the compaction tools 6 are specified to compact bristle bundles 2 positioned in the compaction receptacles 5.
