TECHNICAL FIELD
[0001] The utility model relates to a kind of method for separating bristle bundle from the reserve of loose bristle, wherein, including the bundle separator of separating gap is moved to move through the reserve of loose bristle in separating movement, where bristle bundle is separated from the reserve and the bristle bundle reaches separating gap.
[0002] Furthermore, the utility model also relates to a kind of separating device for separating bristle bundle from the reserve of loose bristle. The device can be designed to implement the method described above. In addition, a brush filling machine comprising such a separating device is also proposed. BACKGROUND
[0003] Bristle bundles are required for manufacturing brushes, such as toothbrushes. The bristle bundles can be separated from the reserve of loose bristle using the bundle separator of a separating device. For this purpose, the bundle separator can be moved through the reserve of loose bristle in a separating movement. Separating gaps formed on the bundle separator move through a separating region on the reserve of loose bristle in this way, whereby the bristle filaments reach the separating gaps and are then present there as bristle bundles.
[0004] With the aid of the bundle separator, the separated bristle bundles can subsequently be fed to a filling tool of a brush filling machine. The filling tool can then extract the bristle bundles from the separating gaps and insert them into the receiving holes of a prepared brush body.
[0005] When separating bristle bundles from the reserve of loose bristle, it is desirable for the separated bristle bundles to have as constant a number of bristle filaments as possible. The number of bristle filaments combined in a bristle bundle is determined by the shape and size of the separating gaps and can influence the use properties of the bristle bundle. The separating gaps should therefore be as completely filled with bristle filaments as possible in each separating process. This enables bristle bundles to be provided which have a uniform or only slightly deviating number of bristle filaments from one another. SUMMARY
[0006] The task of the utility model is therefore to provide a method for separating bristle bundles, a separating device for separating bristle bundles and a brush filling machine of the type mentioned at the outset, which facilitates the reliable and constant filling of the separating gaps with bristle filaments.
[0007] To solve the stated task, a separating device for separating bristle bundles from the reserve of loose bristle is first proposed.
[0008] A separating device for separating tufts of bristles from a supply of loose bristle filaments, the separating device having a bundle separator comprising at least one separating gap, a bristle magazine for the supply of loose bristle filaments and a drive device, the drive device being designed to move the bundle separator comprising the at least one separating gap in a separating movement past a separating region next to the supply of loose bristle filaments, so that the separating gap changes its direction of movement in the separating region on the supply at least twice.
[0009] Furthermore, a method for separating tufts of bristles from a supply of loose bristle filaments is proposed, the method having the means and features for such a method. Thus, in order to solve the task, inter alia, a method for separating tufts of bristles from a supply of loose bristle filaments is proposed, wherein a bundle separator comprising a separating gap is moved in a separating movement past next to the supply of loose bristle filaments, where a tuft of bristles is separated from the supply and reaches into the separating gap, wherein the separating gap changes its direction of movement in the separating region on the supply at least twice, preferably at least three times, when carrying out the separating movement. By the change in the direction of movement of the separating gap in the separating region when a tuft of bristles is separated from the supply of loose bristle filaments, the filling of the separating gap can be facilitated. When a tuft of bristles is separated from the supply of loose bristle filaments, a trailing edge following the direction of movement of the separating gap when carrying out the separating movement on the supply of loose bristle filaments can play a decisive role, which defines the separating gap. In the separating region, the bristle filaments towards the separating gap come into contact with this trailing edge when carrying out the separating movement and are guided into the separating gap by this trailing edge. The filling of the separating gap thus takes place at least partially by the corresponding trailing edge of the separating gap following the direction of movement of the separating gap. By the change in the direction of movement of the separating gap in the separating region on the supply of loose bristle filaments when carrying out the separating movement, the separating gap can be filled with bristle filaments from different directions several times. This facilitates the distribution of the bristle filaments in the separating gap. By the separating gap changing its direction of movement in the separating region on the supply at least twice, preferably at least three times, when carrying out the separating movement, the separating gap can hereby be filled with bristle filaments particularly reliably and as completely as possible.
[0010] An even number of changes in direction of the separating gap in the separating region when carrying out the separating movement can be achieved, which moves into the separating region on one side of the separating region and is removed from the separating region on the other side of the separating region.
[0011] At an odd number of changes in direction, the separating gap can be removed from the separating region by the side, by which the separating gap was moved into the separating region before.
[0012] In one embodiment of the method, the separating gap can pass at least two, preferably at least three return points on the separating region on the stock of loose bristle filaments when the separating movement is carried out. The return points can be provided here, for example, at different positions in the separating region. The separating movement can have a sinusoidal or sinusoidal shape, in which the separating gap moves through the separating region on the stock of loose bristle filaments.
[0013] When the separating gap passes at least two, preferably at least three return points in the separating region when the separating movement is carried out, it is possible for the separating region on the stock of loose bristle filaments to be constructed smaller, without the dwell time of the separating gap in the separating region on the stock of loose bristle filaments being reduced. The dwell time of the separating gap in the separating region when the separating movement is carried out can likewise influence the filling of the separating gap with bristle filaments. The method thus makes it possible to achieve a reduction in the size of the separating region and thereby a reduction in the space requirement for the bristle store, in which the bristle filaments of the stock of loose bristle filaments can be stored.
[0014] In this way, it is possible to provide a separating device whose bristle store can be constructed more compactly. This makes it possible to provide a separating device and also a brush filling machine comprising such a separating device which requires a generally smaller space requirement or whose bristle store can have a larger number of material channels for storing, for example, different types of bristle filaments, with the same space requirement.
[0015] In one embodiment of the method, it is provided that the separating gap passes at least two, preferably at least three return points behind the filling tool in the separating region when the separating movement is carried out. These return points behind can be provided at different positions in the separating region on the stock. By means of the at least two return points behind, bristle filaments can be obtained at different positions in the separating region. This can also facilitate the filling of the separating gap with bristle filaments.
[0016] The separating movement of the separating gap can be produced in one embodiment of the method by superimposition of at least two movements. The at least two movements can be, for example, sinusoidal and / or have different amplitudes. It is also possible for the separating movement to consist of at least two movements which are carried out sequentially. The movements can also be, for example, sinusoidal and / or have different amplitudes here.
[0017] A first movement of the at least two movements can be a main movement of the separating gap, by means of which the separating gap moves between the filling tool and the stock of loose bristle filaments.
[0018] The second movement of the at least two movements can be an additional movement of the separating gap, the separating gap, in particular the separating gap provided thereon, carrying out the additional movement in a separating region on the reserve.
[0019] The main movement can be caused by a drive motor, in particular an output shaft of the drive motor, the separating device and / or the brush filling machine. The additional movement can be caused by an actuator, for example a piezoelectric element. The actuator can be provided, for example, in the force flow between the bundle separator and the drive motor for the bundle separator, the separating gap being formed on the bundle separator.
[0020] The actuator can be designed for length adjustment of a drive rod, by means of which the bundle separator can be connected at least indirectly to the drive motor, in an embodiment of the method and also of the separating device explained in more detail below.
[0021] In this way, the additional movement of the separating gap can be caused by length adjustment of the drive rod with the actuator and, if necessary, superimposed on the main movement of the bundle separator and its separating gap.
[0022] In an embodiment of the method, it is provided that the frequency and / or the amplitude of the additional movement and / or of the main movement is predetermined with a preferably programmable control unit, which can be designed for actuating the actuator and / or the drive motor. If necessary, the frequency and / or the amplitude of the additional movement and / or of the main movement can also be changed by the control unit. In this way, simple adaptation of the method to changing production plans is possible.
[0023] By means of the control unit, return points can be predetermined in the separating region on the reserve of loose bristle filaments in any number and / or position and thus the separation of the bristle bundles from the reserve of loose bristle filaments can be adapted as required.
[0024] To solve the task, a separating device for separating bristle bundles from a reserve of loose bristle filaments is also proposed, which has the means and features for such a separating device. According to the invention, the separating device has a bundle separator comprising at least one separating gap, a bristle store for the reserve of loose bristle filaments and a drive device, which is designed to move the bundle separator comprising the at least one separating gap in a separating movement through a separating region on the reserve of loose bristle filaments in such a way that the separating gap changes its direction of movement at least twice, preferably at least three times, in the separating region. In this way, a separating device is proposed, which can be used to carry out the method explained before and thereby for particularly reliable separation of bristle bundles from the reserve of loose bristle filaments. The separating device can be designed in particular by means of the drive device to carry out the method described.
[0025] The drive device can have a drive motor and a transmission. The drive motor can be connected to the strand separator via the transmission. The transmission can be designed to convert the movement of the output shaft of the drive motor into the movement of the strand separator and its separating gap. The drive motor of the drive device of the separating device can be the drive motor of a brush filling machine, which is equipped with a separating device.
[0026] In one embodiment of the separating device, the transmission has a control curve. The control curve can predetermine the separating movement of the strand separator and thereby the separating movement of the separating gap and is in driving connection with the drive motor of the drive device. The control curve can be provided or formed on a curve carrier, for example a so-called double eccentric, which can be formed as a curve disc. The double eccentric can be part of the transmission and is driven at least indirectly by the drive motor of the drive device.
[0027] The control curve can be formed such that the rotation of the control curve about the rotation axis is transmitted to the strand separator via a mechanical connection, which can have a drive rod. The control curve can be formed such that the separating gap changes its movement direction at least twice, preferably at least three times, in the separating region on the reserve of loose bristle filaments when carrying out the separating movement.
[0028] The mechanical connection can have a tapping device, for example a roller. The tapping device can be connected to the strand separator with the drive rod mentioned previously. The movement of the control curve can then be transmitted to the strand separator via the tapping device and the drive rod.
[0029] In one embodiment of the separating device, the transmission of the drive device has a link transmission, with which at least a part of the separating movement, in particular the previously mentioned main movement, of the separating gap can be brought about.
[0030] The transmission can have an actuator, for example a piezoelectric element, which is designed to bring about an additional movement of the separating gap, for example mentioned previously. In this embodiment of the separating device, the actuator can then bring about at least one of the at least two, preferably three, changes in the movement direction of the separating gap in the separating region on the reserve of loose bristle filaments.
[0031] The actuator can be designed for the length adjustment of the drive rod of the transmission, which is connected to the strand separator. The actuator can be provided here in the force flow between the drive motor and the strand separator. The actuator can be combined not only with the control curve but also with the link transmission.
[0032] The drive device can have a preferably programmable control unit which is designed to control the drive motor and / or the actuator. The control unit can be programmed and / or designed in such a way that the separating gap changes its direction of movement at least twice, preferably at least three times, in the separating region when carrying out the separating movement. The separating device can thus be designed by means of the control unit to carry out the method for separating the bundle of bristles.
[0033] By means of the control unit it is furthermore possible, for example, to adapt the frequency and / or the amplitude of the previously mentioned additional movement and / or the main movement of the separating gap. Preferably, the control unit has a data interface for connecting to a data store, in particular a cloud-based data store. Furthermore, the control unit can be programmable. In this way, for example, the number and / or the position of the return points of the separating movement in the separating region on the reserve of loose bristle filaments can be predetermined.
[0034] By means of the data interface it is possible to call up control programs and thus to influence the separating movement of the separating gap. In particular when the separating device is used in a production complex, it is possible for control programs and / or operating parameters to be stored in the data store by means of the data interface if required and to be made available there for other separating devices. This makes it possible to control a production complex efficiently, which has a plurality of separating devices which can be operated, if necessary, even distributed in different orientations.
[0035] In one embodiment of the separating device, the bundle separator is designed as a circular arc separator and can be deflected about a deflection axis in order to carry out the separating movement. In another embodiment of the separating device, the bundle separator is designed as a separating mobile. The separating mobile can be used to carry out the separating movement in an alternating linear movement. In another embodiment of the separating device, the bundle separator is designed as a separating disc. The separating disc can be deflected or rotated about a deflection axis in order to carry out the separating movement. In particular in the bundle separator designed as a separating disc, the at least one separating gap can carry out an even number of movement changes in the separating region on the reserve of loose bristle filaments when carrying out the separating movement.
[0036] Further, the drive device has a drive motor and a transmission, wherein the drive motor is connected to the bundle separator by means of the transmission, and the transmission is designed to convert the movement of the output shaft of the drive motor into a movement of the bundle separator.
[0037] Further, the transmission has a control curve which determines the separating movement, and / or the control curve is drivingly connected to the drive motor.
[0038] Further, the transmission mechanism has a linkage transmission with which at least a part of the separating movement of the separating gap can be induced.
[0039] Further, with the linkage transmission a main movement of the separating gap can be induced.
[0040] Further, the transmission mechanism has an actuator which is designed to implement an additional movement of the separating gap.
[0041] Further, the actuator is designed for a length adjustment of a drive rod of the transmission mechanism which is connected to the bundle separator, and / or the actuator is arranged in a force flow between a drive motor and the bundle separator.
[0042] Further, the drive device has a control unit which is designed to control the drive motor and / or the actuator.
[0043] Further, the separating gap changes its movement direction at least three times in a separating region on the reserve.
[0044] Further, the actuator is a piezoelectric element.
[0045] Further, the control unit has a data interface for a connection to a data memory.
[0046] Further, the control unit has a data interface for a connection to a cloud-based data memory.
[0047] Further, the control curve is arranged on a double eccentric which determines the separating movement, and / or the double eccentric is drivingly connected to the drive motor. To solve the task, a brush filling machine is also proposed which comprises a separating device and which, in addition, has a filling device comprising a filling tool which is designed to fill the bundle of bristles provided by the separating device into a bristle carrier of a brush.
[0048] The brush filling machine according to the application comprises a separating device and comprises a filling device, the filling device comprising a filling tool which is designed to fill the bundle of bristles provided by the separating device into a bristle carrier.
[0049] The filling device and the separating device can be driven by a common drive motor. The drive motor can then also be referred to as drive motor of the separating device or as drive motor of the filling device.
[0050] The output shaft of the drive motor and the filling tool can be connected to each other via an eccentric. Via the eccentric, the rotation of the output shaft of the drive motor can be converted into an alternating movement of the filling tool. The output shaft of the drive motor can be used as a spindle of the brush filling machine, the movement of which can be transmitted via the eccentric to the filling tool and via the previously mentioned transmission mechanism of the separating device to the bundle separator and the separating gap.
[0051] According to the application, the filling device and the separating device can be driven by a common drive motor.
[0052] According to the application, the output shaft of the drive motor of the drive device of the separating device and the filling tool are connected via an eccentric. BRIEF DESCRIPTION OF DRAWINGS

[0065] In the following description of the drawings, functionally identical elements of the described subject matter also obtain consistent reference signs when different configurations or formations are described.
[0066] Figures 1-8Different brush filling machines, each designated generally as 1, are shown. Each of the brush filling machines 1 shown has a separating device 2 and a filling device 3 comprising a filling tool 4 which is designed to fill tufts 5 of bristles provided by the separating device 2 into a carrier 6 of bristles clamped on the brush filling machine 1.
[0067] The filling tool 4 and the separating device 2 are in driving connection with a common drive motor 7 of the brush filling machine 1. The filling tool 4 and the separating device 2 can thus be driven by the common drive motor 7. The drive motor 7 can therefore be referred to as a drive motor of the separating device 2 and also as a drive motor of the filling device 3 and the filling tool 4.
[0068] An output shaft 8 of the drive motor 7 is in driving connection with the respective filling tool 4 of the filling device 3 in all of the brush filling machines 1 shown in the figures by means of an eccentric 9.
[0069] The separating device 2 serves to separate tufts 5 of bristles from a stock 10 of loose bristle filaments 11. The stock 10 of loose bristle filaments 11 is provided in a bristle magazine 12 of the respective separating device 2. The bristle magazine 12 can also be referred to as a material box and has three material channels 25 in which one type of bristle filament 11 can be provided respectively.
[0070] Each separating device 2 has a tuft separator 13 comprising a separating gap 14, a bristle magazine 12 for the stock 10 of loose bristle filaments 11 and a drive device 15. The drive device 15 is designed to move the tuft separator 13 comprising the separating gap 14 in a separating movement past the separating region 16 next to the stock 10 of loose bristle filaments 11 in such a way that the separating gap 14 changes its direction of movement at least twice, preferably at least three times, in the separating region 16. This facilitates reliable filling of the separating gap 4 with loose bristle filaments 11 for separating tufts 5 of bristles from the stock 10.
[0071] The tuft separator 13 shown in Figures 1 to 8 is a circular-arc separator which is deflectable about a deflection axis. The tuft separator 13 shown in Figure 9 is a linearly movable separating element.
[0072] The drive device 15 of the separating device 2 has the drive motor 7 of the brush filling machine 1 as drive motor and has a transmission 17 by which the drive motor 7 is in driving connection with the tuft separator 13 of the separating device 2.
[0073] The transmission 17 is designed to convert the movement of the output shaft 8 of the drive motor 7 into the aforementioned separating movement. The separating device 2 shown in Figures 1-8 is distinguished in particular by the embodiment of its respective transmission 17.
[0074] In Figures 5-8 the separation device 2 shown in Fig. 1 has a transmission 17 comprising a control curve 18, which is formed on a double eccentric 19. The double eccentric 19 serves as a curve carrier. The control curve 18 here predetermines the separation movement of the beam separator 13 and the separation gap 14 and also the aforementioned change in direction of the separation gap 14 in the separation region. The drive motor 7 is drivingly connected with the double eccentric 19 and thus also with the control curve 18. The beam separator 13 is connected with a drive rod 30. The movement of the control curve 18 can be transmitted to the drive rod 30 and from there to the beam separator 13 by means of a tapping device 31, here a roller and a transmission lever 32.
[0075] In Figures 1-4 the separation device 2 shown in Fig. 2 has a transmission 17, which has a respective link transmission 20 with which at least a part of the separation movement of the beam separator 13 and its separation gap 14, in particular the aforementioned main movement, can be brought about.
[0076] In Figures 2-4 the separation devices 2 shown in Figs. 3 to 8, the respective transmission 17 has in addition an actuator 21, i.e. a piezoelectric element, which is designed and arranged for carrying out an additional movement of the separation gap 14. By means of the actuator 21 it is possible to bring about that the separation gap 14 on the beam separator 13 changes its direction of movement in the separation region 16 when carrying out the separation movement.
[0077] The actuator 21 shown in the figures is respectively designed for a length adjustment of the drive rod 30 of the transmission 17, which is connected with the respective beam separator 13. The actuator 21 is arranged in the force flow between the drive motor 7 and the respective beam separator 13.
[0078] In Figure 1 and 5 the brush filling machine 1 shown in Figs. 3 to 8 respectively has a control unit 21, which is designed for controlling the respective drive motor 7. The drive device 15 of the separation device 2 is equipped in accordance with Figures 2-4 Figs. 3 to 8 with a control unit 22, which is designed for controlling the drive motor 7 and the respective actuator 21.
[0079] Each of the control units 22 shown in the figures has a data interface 23 for connecting with a data store 24, in particular a cloud-based data store.
[0080] By means of the data interface 23, control programs and / or operating parameters for operating the separating device 2, the filling device 3 and generally the brush filling machine 1 can be called up from or stored in the data memory 24 for other brush filling machines 1, separating devices 2 or filling devices 3 and their control units 22. The data interface 23 of the respective control unit 22 is therefore designed as a bidirectional data interface 23.
[0081] Each of the separating devices 2 shown in the figures is designed to carry out a subsequent method for separating a bundle of bristles 5 from a stock 10 of loose bristle filaments 11.
[0082] Here, the bundle separator 13, including its separating gap 14, is moved past the stock 10 of loose bristle filaments 11 in a separating movement. Here, the bundle of bristles 5 is separated from the stock 10, whereby a bundle of bristles 5, including a certain number of loose bristle filaments 11, reaches the separating gap 14.
[0083] The separating gap 14, when carrying out the separating movement, is moved in a separating region 16 on the stock 10 in such a way that it changes its direction of movement at least twice, preferably at least three times, in the separating region 16.
[0084] Figure 11 A diagram is shown in which the angular position of the bundle separator 13 and thereby the position of the separating gap 14 relative to the stock 10 of loose bristle filaments 11 is recorded with respect to the angle of rotation of the output shaft 8 of the drive motor 7. In the diagram of Figure 10 It is clear from the comparison of the diagram of Figure 11 the curve of the separating gap 14 changes its direction of movement three times in the separating region 16 on the stock 10. In Figure 9 the diagram in column B of the diagram of
[0085] By means of Figure 11 the curve of the separating gap 14, the return points 26, 27, 28 of the separating gap 14 in the separating region 16 on the stock 10 are also visible. The two maxima of the curve 11 illustrate the rear return points 26 and 28 of the separating gap 14 in the separating region 16, which have already been reached at an angular position of the bundle separator 13 of slightly less than 75°. The minimum of the curve between the return points 26 and 28 represents the front return point 27, which is passed by the separating gap 14 when carrying out the separating movement.
[0086] In contrast thereto, Figure 10 it is shown that the separating movement of the bundle separator 13, which is carried out according to the curve of Figure 10 the separating gap 14 is guided only into one rear return point, which is of course reached when the bundle separator 13 has already been deflected by 80°.
[0087] Figure 11 It is shown thereby that the associated separating movement of the method according to the application and of the bundle separator 13 can enable a reduction of the separating area 16 on the stock 10 of loose bristle filaments 11 without reducing the duration of the stay of the separating gap 14 in the separating area 16 in which the separation of the bristle bundle 5 takes place. It is thus possible to use a more compact bristle magazine 12 or a bristle magazine 12 with a greater number of correspondingly narrower material channels 25.
[0088] The separating gap 14 can pass at least two, three or, if necessary, a plurality of return points 26, 27 and 28 in all the separating devices 2 shown in the figures when carrying out the separating movement. According to the diagram in column B and also according to the diagram in column C, the separating gap 14 passes three return points 26, 27 and 28 in total when carrying out the method on the separating device 2, which are arranged in the separating area 16 on the stock 10 of loose bristle filaments 11 and, if necessary, at different positions. The separating movement carried out by the separating gap 14 at this time has a sinusoidal course and can be understood as the superposition of two respectively sinusoidal movements. Figure 9 Figure 11 The separating gap 14 passes three return points 26, 27 and 28 in total when carrying out the method on the separating device 2, which are arranged in the separating area 16 on the stock 10 of loose bristle filaments 11 and, if necessary, at different positions. The separating movement carried out by the separating gap 14 at this time has a sinusoidal course and can be understood as the superposition of two respectively sinusoidal movements.
[0089] Figure 11 It is shown that the separating gap 14 passes two respectively rear return points 26 and 28 away from the rear of the filling tool 4 of the respective filling device 3 when carrying out the separating movement, which can be arranged at different positions in the separating area 16 on the stock 10. The separating movement of the separating gap 14 described in column B can be produced by the superposition of at least two movements, which can be respectively sinusoidal and / or have different amplitudes. It is also possible that the separating movement of the separating gap 14 consists of at least two sequentially carried out movements, for example sinusoidal and / or with different amplitudes. Figure 11
[0090] The first movement of the at least two movements can be the main movement of the separating gap 14 at this time, by which the separating gap 14 is moved between the previously mentioned filling tool 4 of the respective brush filling machine 1 and the stock 10 of loose bristle filaments, which is arranged in the bristle magazine 12 of the respective separating device 2. By the main movement, the separating gap 14 can be moved into the separating area 16 and also removed from the separating area 16 again.
[0091] The second movement of the at least two movements can be an additional movement of the separating gap 14, which performs the additional movement on the reserve 10 and thereby on the bristle compartment 12 in the separating region 16. The main movement of the separating gap 14 can be caused by means of the drive motor 7 already mentioned before and in particular by the rotation of the output shaft 8 thereof.
[0092] The additional movement of the separating gap 14 can be caused by means of the actuator 21 already mentioned before or, if necessary, also by means of the drive motor 7.
[0093] The frequency and / or the amplitude of the additional movement and / or of the main movement can be predetermined here by means of the preferably programmable control unit 22, as the control unit which the brush stuffer 1 shown in the figures, the stuffer device 3 and the actuating device of the drive motor 7 of the separating device 2 respectively have. By means of the data interface 23 already mentioned before, the brush stuffer 1 shown in the figures is designed to call up control programs and / or operating and production parameters for actuating the individual functional units of the brush stuffer 1, i.e. the separating device 2 and the stuffer device 3. By means of the data interface 23, control programs, operating and production parameters for other brush stuffers 1 and their separating devices 2 and stuffer tools 3 which are operated in a common production complex can also be stored in the data memory 24.
[0094] Figure 9 The diagram of column A shows a separating movement in which the bundle separator 13 and its separating gap 14 change their direction of movement only once in the separating region 16. Figure 9 The arrows of the reference numeral 13 assigned to the bundle separator in column A respectively illustrate the direction of movement of the bundle separator 13 in the individual phases of the separating movement, which phases are shown in rows I to VII of column A. Figure 9
[0095] Figure 9 The diagram of column A shows a separating movement in which the bundle separator 13 and its separating gap 14 change their direction of movement only once in the separating region 16.
[0096] According to column A, row I, the separating gap 14 enters the separating region 16 on the bristle compartment 12 of the reserve 10 comprising loose bristle filaments 11. According to column A, row II, the movement of the bundle separator 13 and thereby of the separating gap 14 continues through the separating region 16 until the separating gap 14 has reached its only, rearward return point shown in column A, row IV, by passing an intermediate position illustrated in column A, row III.
[0097] From the position in column A, row IV, the separating gap 14 then moves out of the separating region 16 on the reserve 10 again by passing the positions shown in column A, rows VI and VII.
[0098] Figure 9 The diagram in column B illustrates the separating movement of the separating notch 14, in which the separating notch 14 changes its direction of movement three times in the separating region 16.
[0099] According to column B, row I, the separating notch 14 also enters the separating region 16 on the bristle chamber 12. Column B, row II shows that loose bristle filaments 11 reach the separating notch 14 through the edge 29 behind the separating notch 14 in the direction of movement of the separating notch 14 through the separating region 16. If the direction of movement of the separating notch 14 is reversed, the separating notch 14 is filled by the second edge 33 opposite to the first edge 29.
[0100] According to column B, row III, the separating gap 14 has reached its first return point 26. From this first return point 26, the separating movement of the separating gap 14 continues in the opposite direction, thereby the separating gap 14 reaches the position shown in column B, row IV, in which the separating gap 14 has reached its preceding return point 27 in the separating region 16.
[0101] From the previous return point 27, the gap 14 is separated, and then the movement proceeds to the second return point 28. The gap 14 is separated, and then the movement proceeds to the second return point 28 according to the diagram in column B and row V.
[0102] From the return point 28, separate the gap 14 and then through... Figure 9 The positions shown in columns B, rows VI and VII move out of the separated areas 16 on the storage section 10 of the loose bristles 11.
[0103] exist Figure 9 Column B, row III shows the first and thus the last return point 26 of the two subsequent return points 26 and 28, through which the gap 14 passes when the method is implemented.
[0104] In contrast, Figure 9 Column A, row IV shows that the separation gap 14 is given again there in the subsequent return point, clearly indicating further movement.
[0105] That is, from Figure 9 The diagram of column A and row III and Figure 9 A comparison of the diagrams in column B and row IV clearly shows that the proposed method can reduce the width of the separating region 16, in which the separating notch 14 changes its direction of movement at least twice, preferably at least three times, within the separating region 16.
