Description

[0001] Device for compacting bristle bundles, bristle goods manufacturing machine and method for compacting bristle bundles

[0002] The invention relates to a device for compacting bristle bundles for the production of bristle goods, a bristle goods manufacturing machine with such a device and a method for compacting bristle bundles.

[0003] From the publication DE 100 05 249 A1 a brush manufacturing machine with a multiple feed for strand-shaped bristle material, which has a feed device for the bristle strands, as well as with a cutting device for bristle bundles and a feeding device for feeding the bristle bundles to a device for connecting the bristle bundles to a brush body is already known.The brush manufacturing machine is characterized in that the feed device is designed for an independent, controllable feed of the individual bristle strands, that the feed device has a step-by-step positionable conveyor with holes for bristle strands or bristle bundles, that feeds for the bristle strands are provided to a step position of one of the holes in the conveyor, and that one or more shearing devices, which interact with the conveyor, are arranged in the bristle strand feeds for cutting the bristle strands to length.

[0004] For the production of bristle goods, for example brushes such as toothbrushes, bristle filaments are separated from a supply of loose bristle filaments in the form of bristle bundles using a supply means, for example a bundle divider.

[0005] The supply means used for this purpose can have bundle notches, with which the supply means are guided past the supply of loose bristle filaments. A certain number of bristle filaments enter the bundle notches. The bristle filaments arranged in a bundle notch together form a bristle bundle.

[0006] In the bundle notches, the bristle bundles are still unformed and uncompacted. The filament density of the bristle bundles located in the bundle notches is still comparatively low, and the bristle bundles do not yet have the shape they will later have in the finished bristle product. For use in the finished bristle product, it is desirable to increase the filament density of the bristle bundles and, if necessary, to shape the bristle filaments into a specific shape.

[0007] Compacting and, if necessary, shaping bristle bundles involves a certain amount of effort. In practice, for compaction, the bristle bundles are pushed through narrowing channels of so-called funnel plates. The precise manufacture of the funnel plates is comparatively expensive but crucial for achieving the desired degree of compaction. Depending on the desired degree of compaction, compaction may be carried out in several stages, which requires several funnel plates connected in series.

[0008] The object of the invention is to provide a device for compacting bristle bundles, a bristle product manufacturing machine, and a method for compacting bristle bundles that allow efficient and economical compaction of bristle bundles for the production of bristle products. To achieve this object, a device for compacting bristle bundles with the features of the independent claim directed to such a device is first proposed.To achieve the object, a device for compacting bundles of bristles is proposed, which device has a supply means, in particular a bundle divider, with bundle notches, a number of compaction receptacles for bundles of bristles that at least corresponds to the number of bundle notches, and a compaction means for each of its compaction receptacles, wherein the compaction receptacles are designed to remove bundles of bristles from the bundle notches of the supply means and the compaction means are designed to compact bundles of bristles positioned in the compaction receptacles.

[0009] With the supply device, bristle bundles can be separated from a supply of loose bristle filaments and provided in an uncompacted form. With the aid of the device's compacting receptacles, the uncompacted bristle bundles can be removed in a single step from the bundle notches of the supply device and then compacted with the aid of the compacting means to a desired degree of compaction, which the bristle bundles are later to have in a downstream processing step and / or on the finished bristle products. This enables particularly efficient production of bristle products.

[0010] In one embodiment of the device, it is provided that the compression receptacles of the device are formed in one removal plate or in two or more removal plates of the device.

[0011] The compacting means can be moved transversely to the longitudinal direction of the compacting receptacles by a relative movement of the compacting receptacles to the compacting means into a compacting position on or into the compacting receptacles. The relative movement of the compacting receptacles to the compacting means can be carried out transversely, in particular at right angles, to an orientation of bristle bundles and their longitudinal axes in the bundle notches predetermined by the alignment of the bundle notches of the provision means.

[0012] The compaction receptacles can each have an insertion opening through which bristle bundles and / or compaction means can be inserted into the compaction receptacles. The insertion openings can each be aligned transversely or at right angles to a longitudinal axis of the respective compaction receptacle and / or transversely or at right angles to a longitudinal axis of bristle bundles arranged in the compaction receptacles. In this way, it is possible to first remove the bristle bundles from the bundle notches of the provision means in a relative movement executed transversely or at right angles to their longitudinal axis and then to compact them in the same direction.

[0013] The compaction can be effected, for example, by the compacting means passing through the insertion opening of the compaction receptacles into the compaction receptacles in a compaction movement oriented transversely or at right angles to the orientation of the longitudinal axes of the bristle bundles arranged in the compaction receptacles, where they then compress the bristle bundles located therein.

[0014] The insertion openings of the compaction receptacles can be limited by insertion chamfers. The insertion chamfers allow a gentle insertion of the compaction media into the compaction receptacles of the device and can help to prevent damage to the compaction media and / or

[0015] To avoid compaction recordings.

[0016] At this point, it should be noted that the compaction mounts can either be moved themselves to achieve a compacting position within the compaction mounts, or the compaction mounts can be moved relative to the compacting means to perform the previously described relative movements of the compaction mounts to the compacting means. It is also possible for both the compaction mounts and the compacting means to be moved to perform the relative movements for compaction.

[0017] In order to prevent bristle filaments from escaping from a compaction receptacle during compaction, it can be advantageous if at least one compaction means has a sharp-edged transition between its flanks and its end face facing the compaction receptacle to which the compaction means is assigned. Due to the sharp-edged transition between the flanks and the end face of the compaction means, the compaction means can be designed to fit precisely and closely against an inner wall of the compaction receptacle. The sharp-edged transition between the flanks and the end face of the compaction means can prevent bristle filaments arranged in the compaction receptacle from escaping from the compaction receptacle past the compaction means when the previously explained relative movement for compacting the bristle bundles is carried out.

[0018] At least one compaction means can be smoothed and / or hardened on at least one flank that borders on the end face of the compaction means facing a compaction receptacle. The flank can, for example, have a surface roughness of Ra 0.01-1.6, preferably of Ra 0.01-0.04, and / or a hardness, in particular a surface layer hardness with a depth of 1.2-1.8 Rht, of 55-63 HRC, preferably of 60-63 HRC.

[0019] The compacting means can each have a cross-section whose measurable width is smaller than the width of a cross-section arranged in the same cross-sectional plane of the compacting receptacle assigned to them. In this way, the compacting means can be introduced through the insertion openings into the compacting receptacles for compacting bristle bundles.

[0020] At least one compacting means of the device can have an undersize of 0 pm to 50 pm, in particular an undersize of 0 pm to 20 pm, measurable in a width direction of the compacting receptacle assigned to it, relative to a clear width of an insertion opening of the compacting receptacle assigned to it, measurable in the same width direction.

[0021] The previously specified tolerance ranges for the undersize may depend, for example, on the thickness of the bristle filaments in the bristle bundles to be compacted. For bristle filaments with a thickness of 3 mils, the tolerance range can be 0 pm to 20 pm, for example. For larger filament thicknesses, such as bristle filaments with a thickness of 8 mils, a comparatively larger tolerance range may be sufficient, for example, the tolerance range from 0 pm to 50 pm for the previously explained undersize.

[0022] At least one compression fixture of the device can

[0023] Have an undercut. The undercut can expand a volume of the compaction receptacle laterally and / or radially with respect to a longitudinal axis of the compaction receptacle. The longitudinal axis of the compaction receptacle can define the longitudinal orientation of the bristle filaments in the compaction receptacle.

[0024] The undercut allows the compaction receptacle to have a cross-section that is laterally expanded relative to an insertion opening of the compaction receptacle and / or relative to a longitudinal axis of the compaction receptacle. This can promote the formation and compaction of bristle bundles with a cross-sectional shape that deviates from a circular cross-sectional shape and / or is asymmetrical.

[0025] The undercut of the compaction receptacle can be an undercut in a cross-section of the compaction receptacle, which is arranged in a cross-sectional plane oriented at right angles to a longitudinal axis of the compaction receptacle.

[0026] The compacting receptacles can be movable relative to the provisioning means in a removal movement and / or compacting movement oriented transversely or at right angles to a longitudinal axis of the bundle notches, which defines the longitudinal orientation of the bristle bundles in the bundle notches. In this way, it is possible to guide the compacting receptacles past the provisioning means and its bundle notches in order to first remove the bristle bundles from the bundle notches and then compact them using the compacting means.

[0027] The device can have at least one target plate arranged downstream of the compaction receptacles, which comprises target receptacles for receiving the compacted bristle bundles. The target plate can be designed, for example, as a cassette and / or as a transport holder for compacted bristle bundles. After its target receptacles have been loaded with compacted bristle bundles, the target plate can then be fed to a downstream process step for further processing of the bristle bundles.

[0028] The target receptacles of the target plate may have insertion bevels. The insertion bevels can simplify the transfer of the compacted bristle bundles from the compaction receptacles to the target receptacles.

[0029] In a preferred embodiment of the device, the target receptacles of the target plate can be arranged in a hole arrangement that corresponds to the arrangement of bristle bundles on a bristle carrier of a bristle product to be produced. This makes it possible to keep the bristle bundles in the target plate not only already at the desired degree of compaction, but also in the arrangement that the bristle bundles will later assume on a bristle carrier of the bristle product to be produced.

[0030] At least one removal plate of the device can have compaction receptacles that are arranged in a hole pattern that corresponds at least to a partial hole pattern of the hole arrangement of the target receptacles of the target plate. In this way, it is possible to transfer the bristle bundles held in the compaction receptacles of a removal plate of the device directly into target receptacles of the target plate after they have been compacted. If the compaction receptacles of the device are distributed over more than one removal plate, it is possible to equip the target receptacles of the target plate one after the other with bristle bundles in subgroups. The device can have a transfer device for transferring bristle bundles from the compaction receptacles into target receptacles of the aforementioned target plate. With the help of the transfer device, the bristle bundles arranged and compacted in the compaction receptacles can be moved into the target receptacles of the target plate.The transfer device can specify and / or carry out a transfer movement which is oriented in the direction of the longitudinal axes of the compaction receptacles and / or in the direction of the longitudinal axes of the target receptacles and / or in the longitudinal direction of the bristle bundles located in the compaction receptacles.

[0031] The bristle bundles are preferably removed from the bundle notches of the provisioning means and / or subsequently compacted using the compacting means in a removal movement and / or compacting movement that is / are oriented transversely or at right angles to their longitudinal direction. The subsequent transfer of the compacted bristle bundles from the compacting receptacles into the target receptacles of the target plate can then take place in the longitudinal direction of the longitudinal axes of the bristle bundles and thus transversely or at right angles to the removal direction and / or the compacting direction.

[0032] The transfer device can have at least one sliding pin with which the bristle bundles can be pushed in the longitudinal direction of their longitudinal axes from the compaction receptacles into the target receptacles of the target plate. The transfer device preferably has a sliding pin for each compaction receptacle. The at least one sliding pin preferably has the same cross-section as the receiving opening to which the sliding pin is assigned and / or as a bristle bundle compacted therein. The transfer device can have a pin plate for each removal plate with a number of sliding pins that corresponds to the number of compaction receptacles of the respective removal plate.

[0033] In this way, it is possible to transfer the bristle bundles located in the compaction receptacles of a removal plate from the compaction receptacles into corresponding target receptacles of a target plate in one operation using the pin plate and its sliding pins.

[0034] The at least one removal plate and / or at least one compacting means can have a receiving space, for example a slot, in which the provision means is positioned during the removal of bristle bundles.

[0035] The receiving space makes it possible to position the removal plate and / or the at least one compacting means relative to the provisioning means during the removal and / or compacting of bristle bundles such that the provisioning means is at least partially arranged in the receiving space of the removal plate and / or the compacting means. Thus, during the removal and / or compacting, the bristle bundles can be contacted, supported, and / or compacted by the removal plate and / or the compacting means on both sides of the bundle notch of the provisioning means.

[0036] The device can have at least one counterpart assigned to the provision means. By means of the counterpart, bristle bundles located in the bundle notches can be protected against loss on their way from a removal from a supply to the compaction receptacles. Preferably, the device has at least one movable counterpart in the region of the compaction receptacles, which can be moved from an initial position to a target position during and / or by a removal movement and / or compaction movement of the compaction receptacles relative to the provision means. The movable counterpart can thus give way and create space for the movement of the compaction receptacles during removal and / or compaction of the bristle bundles.The movable counterpart can act upon a bundle of bristles located in a compaction receptacle transversely or at right angles to its longitudinal axis and / or contact it until the bundle of bristles is acted upon by a compacting agent for compaction.

[0037] The device can have a compartment slide, a compartment disc, a circular arc and / or a compartment ring as a provision means.

[0038] To achieve the object, a bristle goods manufacturing machine, for example a brush manufacturing machine or a broom manufacturing machine or a paintbrush manufacturing machine, is also proposed, which has a device for compacting bristle bundles according to one of the claims directed to such a device.

[0039] To achieve the object, a method for compacting bundles of bristles using such a device 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 compacting bundles of bristles using a device for compacting bundles of bristles is accordingly proposed, in which bundles of bristles provided with the provision means of the device are removed from the bundle notches of the provision means with the aid of the compaction receptacles of the device and are compacted with the aid of the compaction means of the device. The compaction of the bundles of bristles preferably takes place up to a defined degree of compaction.

[0040] When carrying out the process, the bristle bundles can be compacted, for example, to a degree of compaction of 60% to 90% or to a degree of compaction of 70% to 80% or to a degree of compaction of 75%.

[0041] During compaction of the bristle bundles, the compacting agents enter the compaction receptacles through the insertion openings and come into contact with the bristle bundles located therein. The bristle bundles can be subjected to compaction with the compacting agents transversely and / or at right angles to their longitudinal axes.

[0042] In one embodiment of the method, bristle filaments of at least one bristle bundle are pushed into an undercut of a compaction receptacle of the device during compaction of the bristle bundle. In this way, a reshaping of the bristle bundle during its compaction is possible. The bristle bundle can be reshaped during its compaction such that it acquires a cross-sectional shape that corresponds to the cross-sectional shape of the compaction receptacle with the undercut. The cross-sectional shape of the compacted bristle bundle can, for example, be a cross-sectional shape that deviates from a circular cross-sectional shape and / or is asymmetrical.

[0043] After they have been compacted, the bristle bundles can then be transferred to target receptacles on a target plate of the device. With the help of the target plate, it is possible to make the bristle bundles, compacted as required, available for downstream process steps in the production of bristle products. The target plate can be equipped with a bristle carrier. The compacted bristle bundles can then be pushed with their fastening-side ends through the bundle receptacles of the bristle carrier. The fastening-side ends can then be melted to connect the bristle bundles to the bristle carrier.

[0059] In the following description of various embodiments of the invention, elements that correspond in function, even if they differ in design or shape, are given the same reference numerals. Unless otherwise indicated and where possible, the following description refers to all embodiments of the invention shown in the figures.

[0060] All figures show at least parts of a device for compacting bristle bundles 2, designated as a whole by 1.

[0061] The device 1 has at least one provision means 3, namely a bundle divider, with bundle notches 4 and a number of compaction receptacles 5 for bristle bundles 2 that at least corresponds to the number of bundle notches 4, and a compaction means 6 for each of its compaction receptacles 5.

[0062] The compaction receptacles 5 are designed to remove bristle bundles 2 from the bundle notches 4 of the provision means 3 and the compaction means 6 are designed to compact bristle bundles 2 positioned in the compaction receptacles 5.

[0063] In all embodiments of the device 1 shown in the figures, the device has a plurality of removal plates 7 on which the compaction receptacles 5 are distributed.

[0064] The device 1 shown in Figures 1-6 has a total of two extraction plates 7, each with two compaction receptacles 5. The device 1 shown in Figures 12-20 has a total of four extraction plates 7. Two of the extraction plates 7 each have only one compaction receptacle 5, while the remaining two extraction plates 7 each have two compaction receptacles 5.

[0065] Figures 21-26 show detailed representations of one of the removal plates 7, which has two differently shaped compaction receptacles 5.

[0066] Each compaction receptacle 5 has an insertion opening 8 for bristle bundles 2 and also for the compaction means 6, oriented transversely, namely at right angles to its longitudinal axis and thus at right angles to a longitudinal axis of bristle bundles 2 arranged in the compaction receptacles 5. The compaction means 6 are integrally connected to a holding plate 9, thus forming a materially homogeneous monolithic unit with the latter.

[0067] The compacting means 6 are formed with sharp edges at their transitions 10 between their flanks 11 and their end faces 12 facing the respective compacting receptacle 5. The sharp-edged transitions 10 between the flanks 11 and the end faces 12 of the compacting means 6 prevent bristle filaments 37 from slipping past the compacting means 6 and escaping from the compacting receptacles 5 during compaction of the bristle bundles 2.

[0068] The flanks 11 of the compacting means 6 are, as already explained in the general part of the description, smoothed and also hardened.

[0069] The compaction means 6 each have a

[0070] Latitude direction of the respective

[0071] Compaction receptacle 5 measurable undersize of 0 pm to 50 pm or from 0 pm to 20 pm to a clear width of the insertion opening 8 of the respective compaction receptacle 5 measurable in the same width direction. The tolerance range between 0 gm to 50 gm or 0 gm to 20 gm depends on the filament thickness of the bristle filaments 37 from which the bristle bundles 2 are made, which are to be compacted in the compaction receptacles 5.

[0072] For example, Figures 21-26 show compaction receptacles 5 having an undercut 13. The undercut 13 enables the forming and compaction of a bristle bundle 2 having a cross-sectional shape that deviates from a circular one.

[0073] To remove bristle bundles 2 from the bundle notches 4 of the respective provision means 3, the compaction receptacles 5 together with their removal plates 7 can be moved past the bundle notches 4 in a transverse direction, namely at right angles to a longitudinal axis of the bundle notches 2, which determines the longitudinal orientation of the bristle bundles 2 positioned therein. This is illustrated, for example, by a comparison of Figures 21 to 23, in which the compaction receptacles 5 with the removal plates 7 are shown in different relative positions to the bundle notches 4 of the provision means 3 and also to the compaction means 6.

[0074] The bristle bundles 2 located in the compaction receptacles 5 are compacted by a compacting movement that continues the removal movement. For example, Figure 24 shows the compaction receptacles 5 in the compacting position on the compacting means 6.

[0075] Both the compaction movement and the removal movement are linear movements of the removal plates 7 and the compaction receptacles 5 formed therein, which are carried out relative to the provision means 3 and the compaction means 6.

[0076] From the compaction receptacles 5, the bristle bundles 2 are then transferred in a compacted state to a target plate 14 of the device 1. The target plate 14 has target receptacles 15 for receiving the compacted bristle bundles 2.

[0077] Figure 8 illustrates the equipping of the target receptacles 15 of the target plate 14 with bristle bundles 2 .

[0078] First, the target plate 14 is equipped with a bristle carrier 200. Subsequently, the individual target receptacles 15 of the target plate 14 are equipped with compacted bristle bundles 2. This is done by pushing the compacted bristle bundles 2 from the compaction receptacles 5 of the device 1 in the direction of their longitudinal axes axially out of the compaction receptacles 5 into the target receptacles 15 of the target plate 14 with the aid of the transfer device 19 and its sliding pins 20.

[0079] According to Figure 8, the bristle bundles 2 are pushed into bundle receptacles 201 of the bristle carrier 200 so that their fastening-side ends 202 protrude beyond the bristle carrier 200. In a subsequent processing step, the bristle bundles 2 can be connected to the bristle carrier 200, for example, by melting their fastening-side ends 202. This can be done, for example, in one of the processing stations 16 of the bristle product manufacturing machine 17 shown in Figure 7.

[0080] The target plates 14 shown in the figures are designed as cassettes and also serve as transport holders. The target plates 14 thus also serve to transport the compacted bristle bundles 2 to downstream processing stations 16 of a bristle product manufacturing machine, designated as a whole by 17, as schematically shown in Figure 7.

[0081] The sectional view of a target plate 14 from Figure 11 shows that the target receptacles 15 for receiving the bristle bundles 2 have insertion bevels 18. The insertion bevels 18 facilitate the transition of the compacted bristle bundles 2 into the target receptacles 15 of the target plate 14. The target plates shown in the figures

[0082] 14 have target receptacles 15 which are formed in a hole arrangement on the target plate 14, which corresponds to an arrangement of bristle bundles 2 on the bristle carrier 200 of a bristle product to be produced. From the target receptacles

[0083] 15 of the target plates 14, the bristle bundles 2 compressed to the desired degree of compaction can be provided for connection to the bristle carrier 200 without changing their relative position to one another.

[0084] The extraction plates 7 have compaction receptacles 5, each of which is arranged in a hole pattern that corresponds at least to a partial hole pattern of the hole arrangement of the target receptacles 15 of the target plates 14. This circumstance means that the target plates 14 must be moved to the different extraction plates 7 and the compaction receptacles 5 formed therein in order to fill all of the target receptacles 15, as shown, for example, in Figures 1-6.

[0085] The target receptacles 15 of the target plate 14 are then successively filled with compacted bristle bundles 2, as illustrated, for example, in Figure 8. The target receptacles 15 of the target plates 14 are filled in a similar manner in the device 1 shown in Figures 12-20. Here, the target plates 14 are moved successively to the different removal plates 7 of this device 1 for filling their target receptacles 15.

[0086] All devices 1 shown in the figures also each have 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.

[0087] The transfer devices 19 specify a transfer 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.

[0088] The functioning of the transfer devices 19 is made clear by the illustrations in Figures 21-26.

[0089] 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 pins 20 are aligned perpendicular to a direction of insertion of the bristle bundles 2 and the compaction means 6 into the compaction receptacles 5.

[0090] In the devices 1 shown in the figures, the transfer devices 19 used in each case have a pin plate 21 for each removal plate 7, on which a number of sliding pins 20 is arranged, which corresponds to the number of compression receptacles 5 of the respective removal plate 7.

[0091] The pin plates 21 have guide pins 35. The removal plates 9 and the target plates 14 have corresponding guide bores 36. The guide pins 35 are inserted into the guide bores 36 during the transfer of the bristle bundles 2 from the compaction receptacles 5 into the target receptacles 15 of the target plates 14 and thus determine the relative positions of the pin plates 21, the removal plates 9, and the target plates 14 to one another. This promotes a precise transfer of the compacted bristle bundles 2 into the target receptacles 15 of the target plates 14.

[0092] In particular, Figures 21-26 illustrate that both the removal plates 7 and the compacting means 6 each have at least one receiving space 22. Figures 22 to 24 show that the provision means 3 is arranged in the receiving space 22 of the removal plate 7 during the removal and compacting of bristle bundles 2. These receiving spaces 22 are designed as slots in both the removal plates 7 and the compacting means 6.

[0093] The device 1 further comprises a movable counterpart 23 for each removal plate 7. The movable counterpart 23 serves to prevent loss of bristle bundles 2 arranged in the bundle notches 4 of the provision means 3 until the bristle bundles 2 are removed from the bundle notches 4 and compacted.

[0094] By a movement or during a movement of the removal plate 7 in the direction of the compaction means 6, the movable counterpart 23 can also be lifted according to Figures 21-26.

[0095] The movable counterpart 23 enters the receiving space 22 of the compacting means 6 (see, for example, Figures 23, 24, 25, and 26) and thus creates space for the compaction of the bristle bundles 2 located in the compacting receptacles 5. The movable counterpart 23 thus secures the bristle bundles 2 in the bundle notches 4 until the compacting means 6 come into contact with the bristle bundles 2 and fix them.

[0096] The devices 1 shown also have the

[0097] Provision means 3 has associated counterparts 24 which are designed as rigid counterparts. Rigid counterparts 24 can be clearly seen, for example, in Figures 1-6 and surround the provision means 3 on sections of its peripheral side. The device 1 shown in Figures 1-6 has two rigid counterparts 24 and two movable counterparts 23. The number of movable counterparts 23 thus corresponds to the number of the two removal plates 7.

[0098] By means of the counterparts 23 and 24, the bristle bundles 2 located in the bundle notches 4 are protected against loss on their way from their removal from a supply 25 of loose bristle filaments 37 to the compaction receptacles 5. Figures 1-6 also show that at least one movable counterpart 23 is assigned to each of the compaction receptacles 5 in the region of the two removal plates 7 of this device 1.

[0099] During the removal and compaction movements of the compaction receptacles 5 and the removal plates 7, the movable counterparts 23 are moved from an initial position to a target position. In this case, the movable counterparts 23 reach the target position up to the receiving space 22 of the compaction means 6. Figure 1 shows the two movable counterparts 23 of the device 1 in the receiving spaces 22 of the compaction means 6.

[0100] The device 1 shown in Figures 12 to 20 also has movable counterparts 23 and rigid counterparts 24.

[0101] In the device 1 shown in Figures 1-6, the supply means 3 is designed as a compartment ring. A compartment ring is also shown in the individual part view in Figure 32. Instead of a compartment ring, a circular arc or a compartment disk can also be used, as shown in Figure 33. Figures 12-20 show a device 1 with a further embodiment of a supply means 3 which is designed as a compartment slide and can be moved back and forth in an alternating linear movement between the supply 25 of loose bristle filaments 37 and the compaction receptacles 5 which are formed in the removal plates 7.

[0102] The supply means 3 of the device 1 shown in Figures 1-6 is moved in an alternating pivoting motion. This can be seen from the arrows associated with the supply means 3, which indicate the direction of rotation of the supply means 3 in the respective figure.

[0103] Each of the devices 1 shown has a magazine 26 in which the respective supply 25 of loose bristle filaments 37 is arranged.

[0104] Figure 7 shows a bristle manufacturing machine, designated as a whole by 17. The bristle manufacturing machine 17 has a total of four devices 1 for removing and subsequently compacting bundles of bristles 2. The bristle manufacturing machine 17 has a transfer device 27 which comprises a closed transport path 28 and a plurality of transport carriages 29 with transport receptacles 30 which can be moved along the transport path 28. With the aid of the transport carriages 29 and their transport receptacles 30, the target plates 14 equipped with compacted bundles of bristles 2 on the devices 1 can be transported from the devices 1 to the downstream processing stations 16 of the bristle manufacturing machine 17.

[0105] The devices 1 shown in the figures are suitable for carrying out the following method for compacting bristle bundles 2. With the aid of the provision means 3 of the device 1, initially uncompacted bristle bundles 2 are taken from the supply 25 of loose bristle filaments 37 and prepared for removal and compaction. With the aid of the compaction receptacles 5 of the respective device 1, the bristle bundles 2 are then first removed from the bundle notches 4 of the provision means 3 and subsequently compacted to a defined degree of compaction.

[0106] Depending on the required degree of compaction, the bristle bundles 2 can be compacted, for example, to a degree of compaction of 60% to 90%, of 70% to 80% or even of 75%.

[0107] For example, Figures 1-6, but also Figures 16 and 17 as well as 18 and 19 illustrate that when the method is carried out, bristle filaments 37 of at least one bristle bundle 2 are pushed into an undercut 13 of one of the compaction receptacles 5 of the device 1 when the bristle bundle 2 is compacted. Figure 17 shows the detail marked with a circle in Figure 16 in an enlarged view. It can be clearly seen that the bristle bundle 2 with its bristle filaments 37 is already arranged in the receiving recess 5 of the removal plate 7, but is not yet compacted. The bristle bundle 2 is still at a distance from the compacting agent 6, which has already entered through the insertion opening 8 of the compaction receptacle 5 in the removal plate 7.

[0108] Figure 19 shows the detail marked with a circle in Figure 18 in an enlarged view. By further lifting of the removal plates 7, the bristle bundle 2 with its bristle filaments 37 came into contact with the compacting agent 6 and was compacted. It can be clearly seen that bristle filaments 37 of the bristle bundle 2 shown in Figure 19 within the compaction receptacle 5 got into the undercut 13 of the compaction receptacle 5 during compaction. The undercut 13 is important so that the bristle bundle 2 takes on the cross-sectional shape shown in Figure 19. The cross-sectional shape of the bristle bundle 2, which is shown in Figure 19, deviates from a circular cross-sectional shape.

[0109] Similar undercuts 13 can also be seen in the compaction receptacles 5 of the two extraction plates 7 shown in the right half of Figure 18 and also in the compaction receptacles 5 in the left extraction plate 7 of the two extraction plates 7 shown on the left side in Figure 18. Figures 1 to 6 as well as 21 to 26 and 29 to 31 also show compaction receptacles 5 with undercuts 13.

[0110] As already explained above, the bristle bundles 2 are transferred, after they have been compressed, into target receptacles 15 of ready-made target plates 14 of the device 1. For this purpose, the transfer device 19 shown in the figures with its sliding pins 20 is used. The compressed bristle bundles 2 are pushed with their fastening-side ends 202 through bundle receptacles 201 of a bristle carrier 200 with which the target plate 14 was previously equipped. This can be seen in Figure 8. The fastening-side ends 202 can be melted to connect the bristle bundles 2 to the bristle carrier 200. This can take place in one of the processing stations 16 of the bristle manufacturing machine 17.

[0111] Figures 32 and 33 show two embodiments of provision means 3.

[0112] The provision means 3 shown in Figure 32 is designed as a partition ring. The provision means 3 has a toothing 31 on its inner circumference, with which it can be set into a rotary or pivoting movement via a corresponding drive toothing 32 of the device 1.

[0113] Figure 33 shows a provisioning means 3 designed as a partitioning disc. A drive connection is established here via two edge-side fastening openings 33. A central opening 34 serves to support the partitioning disc. The toothing 32 of the partitioning ring shown in Figure 32 also serves to support the partitioning ring, thus performing a dual function, namely, on the one hand, driving and, on the other hand, supporting the provisioning means 3.

[0114] The invention relates to improvements in the technical field of bristle production. For this purpose, inter alia, a device 1 for compacting bristle bundles 2 is proposed, wherein the device 1 has at least one supply means 3 with bundle notches 4 and a number of compaction receptacles 5 for bristle bundles 2 that at least corresponds to the number of bundle notches 4, and a compaction means 6 for each of its compaction receptacles 5. The compaction receptacles 5 are designed to remove bristle bundles 2 from the bundle notches 4 of the supply means 3, and the compaction receptacles 6 are designed to compact bristle bundles 2 positioned in the compaction receptacles 5.
