Description

The invention relates to a tuft removal device for a brush manufacturing machine with a tuft removal device which has a tuft removal notch on its front side facing a bristle supply when in use, the tuft removal device for removing a bristle bundle from the bristle supply and delivering a received bristle bundle to the brush manufacturing machine with the tuft removal notch between a tuft receiving position and a bundle dispensing position can be moved past the bristle supply, and wherein the bundle removal device has at least one movable pressure piece which can be displaced in the bundle removal notch in order to change a removal cross-section of the latter.

Furthermore, the invention also relates to a brush manufacturing machine with a bristle magazine for a bristle supply and with a bundle removal device which has a bundle remover with a bundle removal notch, the bundle remover for removing a bristle bundle from the bristle supply and for delivering a received bristle bundle to the brush manufacturing machine with the bundle removal notch between a Bundle pick-up position and a bundle delivery position can be moved past the bristle supply held in the bristle magazine.

In addition, the invention also relates to a method for removing a bundle of bristles from a supply of bristles and for transferring it the bristle bundle to a brush making machine using a bundle take-off device.

Such bundle removal devices, brush manufacturing machines and methods are known from the prior art in various embodiments. Such bundle removers are essentially a slide that can be guided past an open side of a bristle magazine and has a bundle remover notch in which the bristles forming the bundle collect when it is passed. The bundle remover transports each bundle of bristles removed from the supply of loose bristles to a processing station, such as a stuffing tool of the brush making machine, and is then moved back to the bristle magazine to remove the next bundle of bristles from the supply of bristles.

The removal cross-section, which can also be referred to as the profile of the bundle removal notch, determines the amount of bristle filaments that can be removed from the bristle supply in one working stroke with the aid of the bundle removal device. In order to be able to pick out bristle bundles of different sizes, i.e. bristle bundles with a different number of bristles or bristle filaments, from the bristle supply with one and the same bundle removal device, the removal cross section of the bundle removal notch, i.e. the profile of the bundle removal notch, can be changed. For this purpose, different devices are already known from the prior art.

So the pamphlet discloses U.S. 2010/066154 A1 a tuft remover having a tuft remover which is essentially a slider sliding on an open side of the bristle magazine and has a bundle removal notch. The bristles forming the bundle collect in the bundle removal notch as they slide past. The bundle remover transports each severed bundle of bristles to a processing station, such as a tufting tool, and is then moved back to the bristle magazine to separate the next bundle of bristles. A bundle of bristles is separated with each working stroke of the bundle remover. The profile of the tufter notch determines the amount of bristles severed with each working stroke of the tufter. In order to be able to separate bundles with different amounts of bristles with a bundle removal device, the effective depth of the bundle removal notch can be changed by covering part of the profile laterally with a cover element.

From the pamphlet EP 0 972 465 A1 Another bundle removal device with a bundle remover is already known, which has a bundle removal notch. There is a carriage associated with the bundle drop notch that allows the size of the bundle drop notch to be adjusted if necessary.

In these previously known devices, with which the effective removal cross-section of the bundle removal notch of the bundle removal device can be varied, some proposed quite complex servo-mechanical solutions that are associated with a relatively large technical effort. On the one hand, a comparatively large amount of installation space is required and, on the other hand, high costs arise due to the large number of precise parts and high assembly costs.

It was also noticed that with the bundle removal devices known from the prior art, it can happen that, especially when the removal cross-section of the bundle removal notch is reduced, the bundles in the bundle removal notch are blocked by the pressure piece or a comparable covering device, which changes the profile of the bundle removal notch can be deformed on one side, for example flattened in a fan shape. As a result, it can happen that individual bristle filaments of the bristle bundle are no longer held in the bundle removal notch and are lost on the way from the bundle receiving position to the bundle dispensing position. This fan effect can also lead to the bundle not being transferred correctly to the tool when the bundle of bristles in the bundle removal notch is transferred to a downstream tufting tool.

The object of the invention is therefore to create a bundle removal device and a brush manufacturing machine as well as a method of the type mentioned above, with which the aforementioned disadvantages can be reduced or even avoided and with which the removal of bristle bundles from a bristle supply and their transfer to a downstream one Brush manufacturing machine is simplified.

This task is in the case of the initially defined bundle removal device by the means and features of claim 1 and in that the pressure piece can be displaced in the bundle removal notch transversely to the direction of longitudinal extension of the bundle removal notch between a first edge running transversely to the direction of longitudinal extension of the bundle removal notch and a second edge of the bundle removal notch opposite the first edge.

In this way, the pressure piece can contact the bristle filaments of a removed bristle bundle in a section of the bristle bundle located between the two free ends of the bristle filaments as soon as the bristle bundle reaches the bundle removal notch. Nevertheless, it is possible to vary the effective removal cross section of the bundle removal notch in a desired manner by means of the pressure piece. Due to the way in which the pressure piece contacts the bristle filaments of the removed bristle bundle laterally, the fan effect described above can be reduced or even avoided. The bristle filaments of the bristle bundle that may protrude on both sides of the pressure piece can be supported by wall sections of the bundle remover that delimit, surround and ultimately define the bundle remover notch. Fanning out of the bristle bundles is reduced or avoided in this way. Thus, the bundle removal notch of the bundle removal notch according to the invention is characterized in that on both sides, i.e. for example above and below, of the pressure piece inserted between the edges of the bundle removal notch there are wall sections which prevent a bristle bundle located in the bundle removal notch from fanning out.

The bristle bundles can be removed from the bristle supply by a recurring movement of the bundle remover between the two extreme positions referred to as the bundle receiving position and the bundle dispensing position. Bristles can get into the bundle removal notch as long as the bundle removal notch is moved past an open side of the bristle magazine. Here the bundle removal notch then slides past the bristles stored in the bristle magazine. If the bristles in the bristle magazine are subjected to pressure and/or gravity, the bristles can slip into the bundle removal notch and be combined there into a bristle bundle.

It can be particularly expedient if a material-free cross-section is formed on the bundle collector between a first peripheral wall of the bundle collector adjacent to the first edge and a second peripheral wall of the bundle collector notch adjacent to the second edge, by which peripheral walls the bundle collector notch is laterally delimited and defined. Through this, the pressure piece can be inserted into the bundle removal notch and/or displaceable in the bundle removal notch. The pressure piece can preferably be pushed into the bundle receiving notch from the direction of a rear side of the bundle collector through this material-free cross section.

The material-free cross section that forms between the first and the second edge or between the first and the second peripheral wall of the thus laterally slotted bundle removal notch can be closed with the help of the pressure piece pushed into the bundle removal notch.

The fan effect can be reduced or even avoided in a particularly reliable manner if the pressure piece can be displaced centrally between the first edge and the second edge in the bundle removal notch. In this context, centered between the first edge and the second edge of the bundle removal notch can mean that a distance between the first edge of the bundle removal notch and the pressure piece corresponds to a distance between the second edge of the bundle removal notch and the pressure piece or is even as large as this. Depending on the orientation of the bundle collector in space, the first edge of the bundle collector notch can be an upper edge of the bundle collector notch and the second edge of the bundle collector can be a lower edge of the bundle collector notch.

It can be advantageous if the bundle removal device, in particular the bundle remover, has a guide along which the pressure piece can be displaced in the bundle removal notch. The pressure piece can be arranged on the bundle collector so that it cannot be lost, in particular by means of the guide, but can still be displaced.

If the bundle removal notch has a concave profile, in particular the shape of a cylindrical shell, the bundle removal notch can be used to remove bristle bundles that have a correspondingly round cross section. In order to avoid the fan effect described above, which can already be reliably avoided or reduced by the circumferential walls of the bundle removal notch on both sides of the pressure piece, it can also be advantageous if a contact surface of the pressure piece facing the bundle removal notch has a concave profile, in particular the shape of a cylindrical shell having. In this way, the contact surface of the pressure piece, which can have a supporting effect on the bristle filaments of the removed bristle bundle, can be maximized. The deeper the curvature or the concave profile is formed in the contact surface of the pressure piece, the greater part of the circumference of the removed bundle of bristles can be supported and thus stabilized with the aid of the pressure piece.

In an advantageous embodiment of the bundle removal device according to the invention, it can be provided that it has an adjusting device which is set up to move the pressure piece in the bundle receiving notch, in particular from working stroke to working stroke of the bundle removal device. In this way, the variability of the bundle removal device is increased. It is possible, for example, to unravel a bristle bundle consisting of a large number of individual bristle filaments in one working stroke, in order to use the adjusting device to change the position of the pressure piece in the bundle removal notch in a subsequent working stroke, and thus, for example, a smaller bristle bundle with a smaller number of individual bristle filaments to be taken from the bristle supply.

However, it is also possible for the adjusting device to be set up to move the pressure piece in the bundle removal notch when the bundle remover is in the bundle pick-up position in front of the bristle supply and/or when the bundle remover is located between the bundle pick-up position and the bundle release position and/or when the bundle remover is moving and/or when the bundle remover is in the bundle release position to move bundle recipient located. Thus, the bundle removal device is special suitable to carry out the method claimed with claim 22. The advantages associated with this method are described in detail below. If the pressure piece is pushed into the bundle removal notch when the bundle remover is in the bundle delivery position, the bundle of bristles arranged there can be ejected from the bundle removal notch with the help of the pressure piece and, for example, transferred to a downstream tamping tool.

The adjusting device can include an adjusting wire which is connected to the pressure piece and can be displaced with a free end of the wire along the inclined surface to raise and lower the adjusting wire relative to an inclined surface and to move the pressure piece in the bundle removal notch. The pressure piece can be pulled back from the bundle removal notch by lifting the control wire and moved into the bundle removal notch by lowering the control wire on the inclined surface or advanced in it. It can be provided that the control wire is passed through the pressure piece. For this purpose, the pressure piece can have an opening or a bore or just a recess through which the control wire runs in its position of use. In this way, a raising and lowering of the control wire can be transferred to the pressure piece connected to the control wire. With regard to the inclined surface along which the free end of the control wire can be displaced, it should be said that this preferably faces away from the front of the bundle collector and, as required, can assume a wide variety of angles to the front. For example, it is conceivable that the inclined surface is aligned at an angle of between 10 and 45 degrees to the front is.

In order to bring about the displacement of the control wire relative to the inclined surface, it can be expedient if the control device comprises a wire roller for winding and unwinding the control wire. If the control wire is unwound from the wire spool, it runs with its free wire end, preferably bent away from the inclined surface hook or eye, wire end on the inclined surface and finally on this, whereby the control wire can be raised and the pressure piece can be adjusted. In this way, the pressure piece can be pulled back in the bundle removal notch. If the control wire is wound onto the wire spool, the result is that the free end of the wire slides down the inclined surface, i.e. the control wire is lowered, whereby the pressure piece is advanced in the bundle removal notch.

If a setting wire is used, the ejection of the tufts of bristles from the tuft take-off notch can occur due to tension on the wire causing it to retract. Wire tension can then move the plunger to an eject position in the bundle removal notch.

For unwinding and winding up the wire roll, the adjusting device can have a link track that can be adjusted, preferably by a motor, relative to the front side of the bundle remover, a sliding block guided in the link track, preferably a link roller, and a link lever. The sliding block can preferably be rotatable, fastened or mounted on the link lever. The wire roll can be connected to the link lever in a rotationally fixed manner. That's the way it is It is possible that when the link track moves in one direction relative to the front of the bundle remover, for example when the distance between the link track and the front of the bundle remover increases, the control wire is wound onto the wire reel, as a result of which the control wire is lowered on the inclined surface and so that the pressure piece can be pushed into the bundle removal notch. It is also possible for the control wire to be unwound from the wire roll when the link track moves relative to the front side of the bundle collector, for example when the distance between the link track and the front side of the bundle collector is reduced, the control wire being unwound by being displaced along the inclined surface raised and so the pressure piece in the bundle removal notch is pulled back to enlarge the removal cross-section.

It can be advantageous in this context if the bundle collector has a wire guide device for the control wire. In this case, this wire guide device can comprise at least one guide groove for the adjusting wire, in which the adjusting wire is displaced in the position of use.

The bundle remover of the bundle remover device can have a particularly compact design if it has a pocket within which the pressure piece and/or the adjusting wire and/or the wire roller and/or the link lever and/or the wire guide device is/are arranged.

In a further embodiment of the bundle removal device according to the invention, it can be provided that the adjusting device communicates with the bundle removal device via a swivel joint associated one-armed adjusting lever, with which the pressure piece can be displaced. In addition to the one-armed adjusting lever, the adjusting device can include a link track that can be adjusted relative to the front side of the bundle remover, in particular by a motor. The adjustment lever can be connected at one joint end via the joint to the bundle collector and at a free end of the lever opposite the joint end can have a sliding block guided in the link path, in particular a link roller, which can be referred to as a cam follower. The pressure piece can act on a lever section between the articulated end and the free end of the lever or be formed on this or connected to it.

In order to change the removal cross-section of the bundle removal notch, the one-armed adjusting lever can be pivoted away from the front side of the bundle remover when the link track is moved in one direction relative to the front side of the bundle remover, for example when the distance between the link track and the front side of the bundle remover is increased, and so that The pressure piece can be pulled back in the bundle removal notch. If the slideway moves in the opposite direction, in particular if the distance between the slideway and the front of the bundle remover is reduced, the one-armed adjusting lever can be pivoted towards the front of the bundle remover and the pressure piece can thus be pushed into the bundle remover notch.

The one-armed adjusting lever can be designed in such a way that a movement of the link track is stocky, for example in a ratio of three to one, is transferred to the pressure piece. A large movement of the link track can thus be converted into a smaller movement of the pressure piece.

In yet another embodiment of the bundle removal device according to the invention, it can be provided that the adjusting device has a two-armed adjustment lever which is connected to the bundle removal device via a joint and with which the pressure piece can be displaced.

It can be expedient if the adjusting device for actuating the pressure piece includes a link track that can be adjusted relative to the front side of the bundle remover, in particular by a motor, in addition to a two-armed adjusting lever, for example, the already mentioned two-armed adjusting lever. The two-armed adjustment lever can have the pressure piece on a first lever arm and a sliding block guided in the link path, in particular a link roller, on a second lever arm arranged beyond the joint. When the link track is moved in one direction relative to the front of the bundle remover, for example when the distance between the link track and the front of the bundle remover increases, the first lever arm can be pivoted in the direction of the front of the bundle remover and the pressure piece can be pushed into the bundle remover notch. As a result, the removal cross section of the bundle removal notch can be reduced in a simple and reliable manner. When the link track moves in the opposite direction, for example when the distance between the link track and the front of the bundle collector is reduced, the first lever arm can move from the front of the bundle collector swiveled away and the pressure piece can be pulled back in the bundle take-off. As a result, the removal cross section of the bundle removal notch can be increased.

It should be mentioned that in all variants of the bundle removal device in which an adjusting lever is provided, the pressure piece can be integrated into the adjusting lever. The pressure piece and the adjusting lever can preferably form a materially homogeneous, monolithic unit, that is, for example, can have been produced in a common production process and can be present in one piece.

The adjusting lever can be offset relative to the pressure piece. In this case, the adjusting lever can be arranged eccentrically on the bundle collector in relation to a cross-sectional center plane. As a result, a material thickness of the bundle collector adjacent to the offset part of the adjusting lever can be greater than in the case of such bundle collectors with adjusting levers that are not offset relative to the pressure piece, which preferably acts centrally. This can result in greater stability of the bundle collector.

The adjusting lever can preferably be arranged flush with an outside or upper side of the bundle collector oriented transversely to the direction of adjustment of the bundle collector.

It is particularly preferred if the bundle remover has a pocket within which the pressure piece and/or the adjusting lever are arranged. In particular in the case of an adjusting lever which is offset or offset laterally relative to the pressure piece, the pocket cut out in the bundle remover must then be not be so deep, which can improve the stability of the bundle collector.

It can also be of particular importance for the reliability of the bundle removal device according to the invention if the front side of the bundle remover, which faces the bristle supply held ready in the bristle magazine, has a closed face or outer contour except for the bundle removal notch. Thus, the individual bristle filaments in the bristle supply of the bristle magazine face an unchanged, closed, homogeneous surface with the front side of the bundle remover, which can result in reduced filament distortion during the tamping process. The pressure piece and/or the control device, in particular the adjusting lever, the link lever, the sliding block, the wire roller and/or the adjusting wire, can be arranged behind the end face and/or shielded from it. In this way, the bundle remover slides past the bristle supply in the bristle magazine with a homogeneous, uninterrupted and offset-free front surface. The bristles held ready within the bristle magazine are thus presented with a closed and even surface up to the bundle removal notch. This has the advantage that undesired bristle distortion or filament distortion when feeding the bristle bundles to the stuffing tool of the brush manufacturing machine with the aid of the bundle remover can be avoided.

It can be particularly advantageous if the pressure piece and, above all, the respective adjusting lever, with which the pressure piece is actuated, are arranged completely beyond the closed end face and are shielded from it.

Grooves, joints or any other misalignment between the moving parts, which could impair a reliable and damage-free removal of bristles from the bristle magazine, can thus be avoided. The end face of the bundle collector, which is closed on the outside, can shield the movable elements arranged inside the bundle collector, such as the control device, the adjusting lever, the link lever, the sliding block, the wire roller and/or the control wire. In this way, undesired contact of these elements with the bristles in the bristle magazine of the brush manufacturing machine can be avoided. The closed end face of the bundle collector can thus serve as a barrier between the supply of bristles held in the bristle magazine and the movable elements of the bundle collector.

In addition, it is possible for the front side of the bundle collector to be curved along an arc of a circle, so that the bundle collector is present as a so-called circular arc divider or circular arc collector.

Furthermore, the bundle collector can be pivotable about a preferably fixed pivot axis between the bundle pick-up position and the bundle release position.

It should be mentioned that all of the above-mentioned link tracks can be arranged on a holder that can be adjusted, preferably by a motor, relative to the front side of the bundle remover. The link tracks and/or the holders can be guided in a longitudinal guide so as to be longitudinally displaceable relative to a frame of the brush manufacturing machine and/or the bundle removal device.

The object mentioned at the outset is also achieved by a brush manufacturing machine having the means and features of claim 21 . According to the invention, in order to achieve the object of a brush manufacturing machine of the type mentioned at the outset, the bundle removal device is a bundle removal device according to one of the claims relating to the bundle removal device.

The object mentioned at the outset is achieved by the method described in claim 22 for removing a bristle bundle from a bristle supply and for transferring the bristle bundle to a brush manufacturing machine, in particular one according to claim 21, preferably using a bundle removal device according to one of claims 1 to 20. supports. This method provides that a removal cross-section of a bundle removal notch is reduced after the bundle removal notch has been filled with a bristle bundle and/or during the movement of the bundle removal device between a bundle pickup position and a bundle delivery position and/or that the removal cross-section of the bundle removal notch is changed when the bundle removal notch is filled and /or that the bundle of bristles located in the bundle removal notch is ejected from the bundle removal notch by means of the pressure piece.

If the removal cross-section of the bundle removal notch is reduced after filling the bundle removal notch, in particular while the bundle removal is on its way to the bundle delivery position, the bristle bundle located in the bundle removal notch can be compacted and the degree of filling of the bundle removal notch can be increased. To reduce the If a bundle removal device according to the invention is used, the pressure piece described above can be pushed into the bundle removal notch. It can be expedient in this context if the bundle removal device has a front counterpart that acts as a stop and extends along an adjustment path of the bundle remover between the bundle receiving position and the bundle release position and is arranged opposite the bundle removal notch. This counterpart can be, for example, a guide plate that is arranged to run parallel to the front of the bundle collector. The pressure piece can press the bundle of bristles located in the bundle removal notch against the counterpart. As a result, the bundle of bristles can be held better in the bundle removal notch and the degree of filling of the bundle removal notch can be increased.

If the bundle removal cross-section of the bundle removal notch is changed when filling the bundle removal notch, it is possible to influence the filling behavior. It is conceivable to specifically increase or decrease the removal cross section of the bundle removal notch during the removal of bristles from the bristle supply of the bristle magazine. If the removal cross-section is deliberately changed, in particular increased, during the removal of bristles from the bristle supply, the bundle removal notch is not filled all at once, but rather homogeneously and possibly also more slowly.

If the bundle of bristles located in the bundle removal notch is ejected from the bundle removal notch by means of the pressure piece, the pressure piece can assume a dual function and a separate ejection mechanism can be dispensed with.

In the following description of various embodiments of the invention, elements that have the same function are given the same reference numbers, even if the design or shape differs.

figure 1 shows a bundle removal device, denoted as a whole by 1, for a brush manufacturing machine 2. The bundle removal device 1 has a bundle removal device 3, which is Figures 1 to 10 is shown in different embodiments of the invention.

Each of the bundle removers 3 shown in the figures is provided with a bundle remover notch 6 on its front side 5 facing a supply of bristles 4 in the position of use. To the Removal of a bristle bundle 7 from the bristle supply 4, which is kept in a bristle magazine 8 of the brush manufacturing machine 2, the bundle remover 3 with its bundle removal notch 6 can be moved past the bristle supply 4 between a bundle receiving position and a bundle dispensing position.

In the case of the bundle remover 3 shown in the figures, this occurs in that the bundle remover 3 is pivoted past an open side 9 of the bristle magazine 8 along an arc of a circle. The bristles 10 stored in the bristle magazine 8 reach the bundle removal notch 6 of the bundle collector 3. This is done by pushers 11 on the bristle magazine 8, with which the individual bristles 10 stored in the bristle magazine 8 are pressed against the front side 5 of the bundle collector 3 to be pressed.

With the help of the bundle remover 3, a bristle bundle 7 taken from the bristle supply 4 can be transported in the bundle removal notch 6 from the bundle receiving position to a bundle delivery position, where it is transferred from the bundle removal notch 6 to a downstream tufting tool 12 of the brush manufacturing machine 2. The bundle of bristles 7 is then stuffed into a brush part body or brush body 14 held ready on a brush holder 13 with the aid of the stuffing tool 12 .

In order to change a removal cross-section of the bundle removal notch 6, the bundle removal device 1 has a movable pressure piece 15, which can be pushed into the bundle removal notch 6 and displaced there as required. How in particular the Figures 2 to 10 make clear, this pressure piece 15 is arranged on the bundle removal device 1 and here specifically on the bundle remover 3 in such a way that it is transverse to the longitudinal direction of the bundle removal notch 6 between a first edge 16 running transversely to the longitudinal direction of the bundle removal notch 6, which can also be referred to as the upper edge 16 , and a second edge 17 of the bundle removal notch 6 opposite the first edge 16, which can also be referred to as the lower edge 17, in the bundle removal notch 6 is displaceable.

The figures also show that a material-free cross-section 21 is formed on the bundle remover 3 between a first peripheral wall 19 of the bundle remover notch 6 adjacent to the first edge 16 and a second peripheral wall 20 of the bundle remover notch 6 adjacent to the second edge 17, through which the pressure piece 15 can be pushed from the direction a rear side 22 of the bundle collector 3 can be inserted into the bundle collector's notch and slidably in the bundle collector's notch 6 . The material-free cross section 21 of the bundle collector 3 can also be referred to as a push-through opening for the pressure piece 15 .

The pressure piece 15 is arranged in such a way that it can be displaced centrally between the first edge 16 and the second edge 17 and into the bundle removal notch 6 . The bundle collector 3 comprises a guide 18 along which the pressure piece 15 can be displaced in the bundle collector notch 6 . Circumferential walls 19 and 20 are thus present both above and below the pressure piece 15, by which the bundle removal notch 6 is laterally delimited and on which a bundle of bristles 7 located in the bundle removal notch 6 is held and supported can be. The initially described effect of the bristle bundles 7 fanning out within the bundle removal notch 6 can thus be reduced or even avoided.

All pressure pieces 15 shown in the figures have a contact surface 23 facing the respective bundle removal notch 6 in the position of use, which has a concave profile and specifically has the shape of a cylindrical shell.

The bundle removal device also has an adjusting device 24 . This adjusting device 24 is set up to move the pressure piece 15 in the bundle removal notch 6 in order to change the removal cross section of the bundle removal notch 6 . A change in the removal cross section of the bundle removal notch 6 is possible from working stroke to working stroke of the bundle remover 3 . In addition, however, the adjusting device 24 is also set up to press the pressure piece 15, if necessary, when the bundle remover 3 is in the bundle pick-up position, when the bundle remover 3 is located between the bundle pick-up position and the bundle release position, in particular while it is being moved between these two positions, and when the bundle remover is in the bundle release position 3 in the bundle removal notch 6. This enables the procedure described below to be carried out.

The Figures 1 to 4 now show a first embodiment of such an adjusting device 24.

According to the Figures 1 to 4 the adjusting device 24 includes an adjusting wire 25. This adjusting wire 25 is connected to the pressure piece 15 connected and passed through it. To raise and lower the control wire 25 and thus to shift the pressure piece 15, the control wire 25 is shifted with a free wire end 26, which is bent into an eye or hook, along an inclined surface 27 facing away from the front side 5 of the bundle collector 3. If the end of the wire 26 runs against the inclined surface, the control wire 26 is raised. By raising the control wire 25, the pressure piece 15 is withdrawn from the bundle removal notch 6. By lowering the control wire 25, ie when the free wire end 26 of the control wire 25 slides down on the inclined surface 27, the pressure piece 15 is moved into the bundle removal notch 6, whereby the removal cross section of the bundle removal notch 6 is reduced.

For winding and unwinding the control wire 25 includes the control device 24 in which in the Figures 1 to 4 For winding and unwinding the wire roll 28, the adjusting device 24 has a link track 29 that can be adjusted by motor relative to the front side 5 of the bundle remover 3, a sliding block 30 guided in the link track 29, and a link lever 31. In the present case, the sliding block 30 is designed as a link roller 30 and is rotatably mounted on the link lever 31 . The wire roll 28 is non-rotatably connected to the sliding block 30 at an opposite end of the link lever 31 with this. If the distance between the link path 29 and the front side 5 of the bundle collector 3 increases, the control wire 25 is wound onto the wire roll 28 by a corresponding rotation of the wire roll 28 . This is done by the linear movement that the link track 29 relative to the front side 5 of the bundle remover 3, is converted into a rotational movement of the wire roll 28 via the link lever 31 and the non-rotatable connection between the link lever 31 and the wire roller 28. As a result, the control wire 25 is wound up or down from the wire roll 28, depending on the direction in which the link track 29 is moved relative to the front side 5 of the bundle collector 3.

When the control wire 25 is wound onto the wire reel 28 , the free wire end 26 is lowered on the inclined surface 27 or slides down on the inclined surface 27 . The movement of the control wire 25 is also transmitted to the pressure piece 15 via the connection between the control wire 25 and the pressure piece 15 . In this way, when the control wire 25 is lowered, ie when the link track 29 is moved away from the front side 5 of the bundle collector 3, it is pushed into the bundle collector notch 6.

If a distance between the link path 29 and the front side 5 of the bundle remover 3 is reduced, the control wire 25 is unwound from the wire roll 28 accordingly. The linear adjustment movement of the link track 29 is in turn converted via the link lever 31 into a rotary movement of the wire roller 28, which causes the control wire 25 to be pushed up with its free wire end 26 along the inclined surface 27, as a result of which the control wire 25 is raised and so that Pressure piece 15 is withdrawn in the bundle reduction notch 6 to increase the reduction cross-section of the bundle reduction notch 6.

According to the Figures 1 to 4 the bundle remover 3 of the bundle remover device 1 shown there has a wire guide device 32 . This wire guide device 32 also includes a guide groove 33 through which the control wire 25 is passed. The bundle collector 3 has a pocket 34 within which the pressure piece 15, the control wire 25, the link lever 31 and also the wire guide device 32 are arranged.

The Figures 5 to 7 show a further embodiment of a bundle collector 3 according to the invention. It is provided that this has an adjusting device 24 for actuating the pressure piece 15, which comprises a one-armed adjusting lever 36 connected to the bundle collector 3 via a joint 35. With the help of this one-armed adjusting lever 36, the pressure piece 15 can be displaced in the bundle removal notch 6 in order to change the removal cross-section. In addition to the one-armed adjusting lever 36, the adjusting device 24 also includes a link track 29 that can be adjusted relative to the front side 5 of the bundle remover 3 by means of an actuator 48, i.e. by means of a drive and thus by a motor.

The one-armed adjusting lever 36 is articulated at one joint end 37 via the joint 35 to the bundle collector 3 and at a free lever end 38 opposite the joint end 37 is provided with a sliding block 30 guided in the link track 29, which is also a link roller 30 in this exemplary embodiment . The pressure piece 15 is arranged in a lever section 39 between the joint end 37 and the free lever end 38 or is formed on this. If the distance between the link track 29 and the front side 5 of the bundle remover 3, the one-armed adjusting lever 36 is pivoted away from the front side 5 of the bundle remover 3 and the pressure piece 5 is thus retracted in the bundle remover notch 6. When the distance between the link track 29 and the front side 5 of the bundle remover 3 is reduced, the one-armed adjusting lever 36 is pivoted towards the front side 5 of the bundle remover 3 and the pressure piece 15 is thus pushed into the bundle remover notch 6, i.e. the cross section of the bundle remover notch 6 is reduced.

The Figures 8 to 10 show a further embodiment of a bundle remover 3 according to the invention, which is used in a bundle remover 1 as shown in figure 1 is shown, can be used.

In this embodiment, an adjusting device 24 is provided which has a two-armed adjusting lever 40 which is connected to the bundle collector 3 via a joint 35 and with which the pressure piece 15 can be displaced.

In addition to the two-armed adjusting lever 40, the adjusting device 24 for actuating the pressure piece 15 also includes a link track 29 that can be adjusted by motor relative to the front side 5 of the bundle remover 3. The two-armed adjusting lever 40 has the pressure piece 15 on a first lever arm 41 and on a second lever arm 41, on the other side of the Joint 35 arranged second lever arm 42 on a sliding block 30 guided in the link track 29 . This sliding block 30 is expediently present here as a link roller 30 which facilitates its movement in the link path 29 . If the distance between the link track 29 and the front side 5 of the Bundle collector 3, the first lever arm 41 is pivoted in the direction of the front side 5 of the bundle collector 3 and the pressure piece 15 is pushed into the bundle collector's notch 6 to reduce the collector's cross-section.

The first lever arm 41 is pivoted away from the front side 5 of the bundle remover 3 when the distance between the link track 29 and the front side 5 of the bundle remover 3 decreases, and the pressure piece 15 is thus pulled back in the bundle remover notch 6 . As a result, the removal cross section of the bundle removal notch 6 can be enlarged.

The Figures 5 to 10 make it clear that the pressure piece 15 is integrated into the corresponding adjustment lever 36, 40 in each case. The sectional views according to figures 7 and 10 show that the pressure piece 15 and the respective adjusting lever 36, 40 form a materially homogeneous, monolithic unit, that is to say they are made in one piece. At the in figure 10 Illustrated embodiment of the bundle remover 3 can be seen that the adjusting lever 36, 40 is sold relative to the pressure piece 15. This means that there is a shoulder or a step in the transition between the pressure piece 15 and the adjustment lever 36, 40, so that the adjustment lever 36, 40, due to the centric arrangement of the pressure piece 15 in relation to a transverse extension of the bundle collector 3, is eccentric on the bundle collector 3 is arranged. This has the consequence that the bundle buyer 3 according to figure 10 can have a greater material thickness in a section shown below the adjusting lever 36, 40. This favors the stability of the entire bundle collector 3.

figure 10 also shows that the respective adjustment lever 36, 40 is arranged flush with an outer side 43 of the bundle remover 3, which is oriented transversely to the direction of adjustment of the bundle remover 3. Thus, the adjusting lever 36, 40 does not protrude beyond the outside 43 of the bundle remover 3.

According to the in the figures 7 and 10 Illustrated exemplary embodiments of different bundle collectors 3 according to the invention each have a pocket 34 within which both the pressure piece 15 and the respective adjusting lever 36, 40 are arranged. It can be seen that the depth of these pockets 34 is at least as great as a thickness of the respective adjusting lever 36, 40 measured in cross section.

Especially from the figures 4 , 6 and 9 It can be seen that the front side 5 of the bundle collectors 3 shown there each have an end face 44 or outer contour that is closed except for the bundle collector notch 6 . In this way, the bundle remover 3 slides past the bristle supply 4 in the bristle magazine 8 with a homogeneous, uninterrupted and offset-free end face 44 . The bristles 10 held ready within the bristle magazine 8 are thus presented with a closed and uniform surface up to the bundle removal notch 6 . This has the advantage that undesired bristle distortion or filament distortion when feeding the bristle bundles 7 to the stuffing tool 12 of the brush manufacturing machine 2 with the aid of the bundle remover 3 can be avoided. It is particularly advantageous that the pressure piece 15 and above all the respective adjustment lever 36, 40, with which the pressure piece 15 is actuated, are arranged completely beyond the closed end face 44 and are shielded from it is. Grooves, joints or any other misalignment between the moving parts, which could impair a reliable and damage-free removal of bristles 10 from the bristle magazine 8, can thus be avoided. The outwardly closed end face 44 of the bundle collector 3 can shield the movable elements arranged inside the bundle collector 3, such as the control device 24, the adjusting levers 36, 40, the link lever 31, the sliding block 30, the wire roller 28 and/or the adjusting wire 25 and prevent these elements from contacting the bristles 7. The end face 44 thus also serves as a barrier between the supply of bristles 4 held in the bristle magazine 8 and the movable elements of the bundle collector 3.

All bundle collectors 3 shown in the figures have a front side 5 which is curved along an arc of a circle. The bundle collectors 3 can thus also be referred to as arc collectors or arc dividers.

All of the bundle removers 3 shown in the figures can be pivoted about a pivot axis 45 between the bundle pick-up position and the bundle release position. The sliding track 29 is arranged on a holder 46 that can be adjusted by a motor relative to the front side 5 of the bundle remover 3 . The motor-adjustable holder 46 is guided in a linear guide 47 so that it can be displaced longitudinally and can be displaced longitudinally in at least two directions relative to the front side 5 of the bundle collector 3 by means of the actuator 48 .

The bristle magazine 8 of the brush manufacturing machine 2 for the bristle supply 4 can be rotated or pivoted relative to a frame 49 of the brush manufacturing machine 2 . For example, to be able to fill up the bristle magazine 8 more easily.

With the bundle removal device 1 described above and the brush manufacturing machine 2 described above, the following method for removing a bristle bundle 7 from a bristle supply 4 and for transferring the bristle bundle 7 to the stuffing tool 12 of the brush manufacturing machine 2 can be carried out. It is provided that the removal cross-section of the bundle removal notch 6 is reduced after the bundle removal notch 6 has been filled with a bristle bundle 7 . The pressure piece 15 presses against the bristle bundle 7 located in the bundle removal notch 6. As a result, the bristle bundle 7 is held clamped between the pressure piece 15 and a front counterpart 50 of the bundle removal device 1 and the filling level of the bundle removal notch 6 increases.

figure 1 shows that the front counterpart 50 of the bundle removal device 1 is a guide plate bent parallel to the front side 5 of the bundle removal device 3, which extends between an edge of the open side 9 of the bristle magazine 8 and thus between the bundle receiving position and the bundle dispensing position and acts as a contact surface for the in the bundle removal notch 6 positioned bristle bundles 7 is used.

Furthermore, the bundle removal device 1 also has a rear counterpart 51, which has essentially the same structure as the front counterpart 50 and a second open side 52 of the Bristle magazine 8 closes as long as 8 bristles 10 are to be removed from the first open side 9 of the bristle magazine.

The adjusting device 24 is also set up to change the removal cross section of the bundle removal notch 6 when filling the bundle removal notch 6 in order to influence the filling behavior.

When the bundle remover 3 has reached the bundle delivery position, in which the bundle remover notch 6 is located in the tamping tool 12, the bristle bundle 7 located in the bundle remover notch 6 is ejected from the bundle remover notch 6 by means of the pressure piece 15 and thus transferred to the tamping tool 12 for further processing.

For improvement in the field of tufting apparatuses, the tufting apparatus 1 having the tufting notch 6 variable in section of the tufting section, the brush manufacturing machine 2 equipped therewith, and the method described above are proposed. In the bundle removal device 1 according to the invention it is provided that it has the pressure piece 15 which can be displaced between the first edge 16 and the opposite second edge 17 of the bundle removal notch 6 to change the removal cross section of the bundle removal notch 6 in the latter.
