Description

Bundle picking device and brush making machine

The invention relates to a bundle picking device for a brush making machine having a bundle pickup having a bundle picking notch on its front side facing a bristle supply, the bundle picking device for picking up a bristle bundle from the bristle stock and delivering a picked bristle bundle to the brush making machine with the bundle picking notch between a bundle picking position and a bundle delivery position is movable past the bristle supply, and wherein the bundle removal device has at least one movable pressure piece which is displaceable therein to change a decrease cross section of the bundle removal notch.

The invention also relates to a brush making machine having a bristle magazine for a bristle stock and a bundle picker having a bundle picker with a bundle picking notch, the bundle picker for picking up a bundle of bristles from the bristle stock and delivering a picked bristle bundle to the brush making machine with the bundle picking notch between a bundle picker Bundle pickup position and a

Bundle delivery position on the held in the bristle magazine bristle supply is moved past.

Moreover, the invention also relates to a method for removing a bundle of bristles from a bristle supply and for transfer of the bristle bundle to a brush making machine using a bundle picking device.

Such bundle picking devices, brush making machines and also methods are known from the prior art in different embodiments. Such bundle pickups are essentially a slide which can be guided past an open side of a bristle magazine and has a bundle pick-off notch in which the bristles forming the bundle collect as they pass by. The bundle picker transports each bristle bundle removed from the supply of loose bristles to one

Processing station, such as a tamping tool of the brush making machine, and is then moved back to the bristle magazine to remove the next bundle of bristles from the bristle supply.

The acceptance 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 dispense different bristle bundles, ie bristle bundles with a different number of bristles or bristle filaments, from the bristle supply with one and the same bundle removal device, the acceptance cross section of the bundle removal notch, ie the profile of the bundle removal notch, can be changed. For this purpose, different devices are previously known from the prior art. In these prior art devices with which the effective acceptance cross section of the bundle decrease notch of

Bundle picking device varies, become partial quite elaborate servo-mechanical solutions proposed, which are associated with a relatively large technical effort. On the one hand comparatively much space is required and on the other hand high costs arise due to many precise parts and high assembly costs.

Furthermore, it is noticed that it is possible in the previously known from the prior art beam extraction devices that, especially if the decrease in cross section of the bundle decrease notch is decreased, the bundle in the bundle decrease score by the pressure piece or similar covering, the profile ^'of the bundle decrease notch can change, deformed on one side, for example, be flattened fan-shaped. As a result, individual bristle filaments of the boron bundle may no longer be held in the bundle removal notch and may be lost on the way from the bundle receiving position to the bundle discharge position. Even when transferring the bristle bundle located in the bundle removal notch to a downstream stuffing tool, this fan effect can lead to the bundle not being correctly transferred to the tool.

The object of the invention is therefore to provide a bundle removal device and a brush manufacturing machine and a method of the type mentioned, with which can reduce or even avoid the aforementioned disadvantages and with which the removal of bristle bundles from a bristle supply and their transfer to a downstream Brush making machine is simplified.

This task is performed with the bundle acceptance mevorrichtung by the means and features of claim 1 and in particular solved in that the pressure piece is transversely to the longitudinal direction of the bundle removal notch between a first, transverse to the longitudinal direction of the bundle decrease notch edge and a first edge opposite the second edge of the Bundelabnahmekerbe displaceable in the bundle removal notch ,

In this way, the pressure piece can contact the bristle filaments of a removed bundle of bristles in a section of the bundle of bristles located between the two free ends of the bristle filaments, as soon as the bundle of bristles reaches the bundle removal notch. Nevertheless, it is possible by means of the pressure piece to vary the effective acceptance cross section of the bundle removal notch in a desired manner. Due to the way in which the pressure piece laterally contacts the bristle filaments of the removed bristle bundle, the fan effect described above can be reduced or even avoided. The bristle filaments of the bundle of bristles possibly protruding on both sides of the pressure piece can be supported by wall sections of the bundle collector which bound, surround and finally define the bundle acceptance notch. Fanning the bristle bundles is reduced or avoided. Thus, the bundle removal notch of the bundle pickup according to the invention is characterized in that on both sides, so for example above and below, of the introduced between the edges of Bundelabnahmerkerbe pressure piece wall sections are present, which prevent fanning of a bundle in the collection bundle notch bristle bundle. The removal of the bundles of bristles from the bristle supply can be effected by a recurring movement of the bundle pick-up between the two extreme positions, referred to as the bundle receiving position and the bundle dispensing position. In this case, bristles can enter 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. When the bristles in the bristle magazine are subjected to pressure and / or gravitational force, the bristles may slip into the bundle take-off notch and be combined there to form a bundle of bristles.

It may be particularly useful if at the bundle takers between a first peripheral wall adjacent the first peripheral wall of the bundle and a second edge adjacent the second peripheral wall of Bundleabnahmekerbe, through which peripheral walls, the bundle removal notch is laterally defined and defined, a material-free cross-section is formed. Through this, the pressure piece can be inserted into the bundle removal notch and / or slidable in the bundle removal notch. Preferably, the pressure piece can be inserted from the direction of a back of the bundle picker in the bundle receiving notch through this material-free cross section. In this case, the material-free cross-section, which forms between the first and the second edge or between the first and the second peripheral wall of the thus laterally slotted Bundleabnahmekerbe be closed by means of the inserted into the bundle removal notch pressure piece. The fan effect can be particularly reliably reduced or even avoided if the pressure piece is displaceable centrally between the first edge and the second edge in the bundle removal notch. Centric between the first edge and the second edge of the bundle removal notch may in this context 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 decrease notch and the pressure piece or even as large as this. Depending on the orientation of the bundle picker in the space, the first edge of the bundle take-off notch may be an upper edge of the bundle take-off notch and the second edge of the bundle take-off notch may be a lower edge of the bundle take-off notch. It can be advantageous if the bundle removal device, in particular the bundle pickup, has a guide along which the pressure piece guided in the bundle removal notch is displaceable. In this case, the pressure piece, in particular by means of the guide, captive, but still be slidably disposed on the bundle takers.

If the bundle removal notch has a concave profile, in particular the shape of a cylindrical shell, bristle bundles having a correspondingly round cross section can be formed with the aid of the bundle removal notch. To avoid the fan effect described above, which can be reliably avoided or reduced even by the existing on either side of the pressure piece peripheral walls of Bundleabnahmekerbe, it may also be beneficial if the Bün- delabnahmekerbe facing contact surface of the pressure piece a concave profile, in particular the shape a cylinder 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 bristle bundle can be supported by means of the pressure piece and thus stabilized.

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 the working stroke to the working stroke of the bundle removal device. In this way, the variability of the bundle picking device is increased. Thus, it is possible, for example, to grasp a bristle bundle consisting of a large number of individual bristle filaments in a working stroke in order to change the position of the pressure piece in the bundle take-off notch in a subsequent working stroke with the aid of the adjusting device and thus, for example, a smaller bristle bundle with a smaller number of bristles remove individual bristle filaments from the bristle supply.

But it is also possible that the adjusting device is adapted to the pressure piece in the bundle take-off notch located in bundle receiving position in front of the bristle supply bundle takers and / or located between the bundle receiving position and the bundle delivery position bundle takers and / or moving bundle takers and / or in bundle discharge position to move the existing bundle customer. Thus, the bundle picking device is special suitable to carry out the method claimed in claim 22. The advantages associated with this method are described in detail below. If the pressure piece is inserted into the bundle removal notch with bundle pickup located in the bundle delivery position, the bundle of bristles arranged there can be removed from the bundle by means of the pressure piece

Bundle removal score ejected and passed, for example, to a downstream StopfWerkzeug. In this case, the adjusting device may comprise a control wire which is connected to the pressure piece and for raising and lowering of the actuating wire relative to an inclined surface and the displacement of the pressure piece in the bundle removal notch with a free wire end along the inclined surface is displaceable. In this case, the pressure piece can be withdrawn by lifting the control wire from the bundle removal notch and moved by lowering the control wire on the inclined surface in the bundle removal notch into or advanced in this. It can be provided that the control wire is passed through the pressure piece. For this purpose, the pressure piece may comprise an aperture or a bore or even a recess through which the actuating wire extends in its position of use. In this way, a raising and lowering of the actuating wire can be transferred to the pressure piece connected to the actuating wire. With respect to the inclined surface, along which the adjusting wire can be moved with its free end, it should be said that they can preferably be turned away from the front side of the bundle and, depending on requirements, can occupy different angles to the front. For example, it is conceivable that the inclined surface is aligned at an angle between 10 and 45 degrees to the front is.

In order to effect the displacement of the actuating wire relative to the inclined surface, it may be expedient if the adjusting device comprises a wire reel for winding and unwinding of the actuating wire. If the control wire unwound from the wire reel, this runs with his free, 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 withdrawn in the bundle removal notch. If the positioning wire is wound onto the wire reel, this causes the free end of the wire to slide down the inclined surface, thus lowering the positioning wire, thereby advancing the pressure piece in the bundle removal notch.

If a positioning wire is used, ejection of the bundles of bristles from the bundle removal notch may occur due to tension of the wire which will return it. The wire tension may then move the pad to an eject position in the bundle removal notch.

For unwinding and winding the wire reel, the adjusting device may have a relative to the front of the bundle pickup, preferably motorized, adjustable slide track, guided in the slide track sliding block, preferably a link roller, and a crank lever. In this case, the sliding block may preferably be rotatable, attached to the crank lever or stored. The wire reel can be rotatably connected to the crank lever. That's the way it is it is possible for the positioning wire to be wound onto the wire reel upon movement of the guide track in a direction relative to the front face of the bundle picker, for example at an increase in the distance between the guide track and the front face of the bundle pick-off, whereby the positioning wire on the inclined face lowered and so the pressure piece is inserted into the bundle removal notch. Furthermore, it is possible that the actuating wire is unwound from the wire reel during a movement of the slide track relative to the front side of the bundle pickup, for example, with a reduction in the distance between the guide track and the front of the bundle pickup, the actuating wire by moving along the inclined surface lifted and so the pressure piece in the bundle removal notch is retracted to increase the Abnahme¬querschnitts.

It may be advantageous in this context if the bundle pickup has a wire guide device for the positioning wire. In this case, this wire guide device may comprise at least one guide groove for the control wire, in which the control wire is moved in the position of use.

A particularly compact shape can be obtained by the bundle pick-up of the bundle removal device, if it has a pocket, within which the pressure piece and / or the positioning wire and / or the wire reel and / or the gate lever and / or the wire guiding device is / are arranged.

In a further embodiment of the bundle removal device according to the invention, provision can be made for the adjusting device to be connected to the bundle picker via a rotary joint having connected one-armed lever, with which the pressure piece is displaceable. The adjusting device may comprise, in addition to the one-armed adjusting lever, a guide track which is adjustable relative to the front side of the bundle pick-up, in particular by means of a motor. In this case, the adjusting lever can be hingedly connected at one end of the joint via the joint with the bundle pickup and at a joint end opposite the free end of a lever guided in the slide track sliding block, in particular a sliding roller, which can be referred to as a curve follower. The pressure piece may act on a lever portion between the joint end and the free end of the lever or be formed on this or connected thereto. In order to change the acceptance cross section of the bundle removal notch, the one-armed adjustment lever can be pivoted away from the front side of the bundle pick-up when the guide web moves in one direction relative to the front side of the bundle pickup, for example at a size of the distance between the link web and the front side of the bundle pickup and so the pressure piece in the Bundleabnahmekerbe be withdrawn. In a movement of the slide track in the opposite direction, in particular at a reduction in the distance between the slide track and the front of the bundle, the one-armed lever can be pivoted according to the front of the bundle and towards the pressure piece are inserted into the bundle removal notch. The one-armed lever can be configured so that a movement of the slide track stocky, for example in a ratio of three to one, is transferred to the pressure piece. A large movement of the slide track can be implemented in a smaller movement of the pressure piece.

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

It may be expedient if the adjusting device for actuating the pressure piece next to one, for example, the already mentioned two-armed lever comprises a relative to the front of the bundle pickup, in particular motor-adjustable slide track. On a first lever arm of the two-armed lever, the pressure piece and on a second, arranged beyond the joint second lever arm guided in the slide track sliding block, in particular a guide roller having. Upon movement of the slide track in one direction relative to the front of the bundle picker, for example, an increase in the distance between the slide track and the front of the bundle pickup, the first lever arm can be pivoted toward the front of the bundle pickup and the thrust piece are inserted into the bundle removal notch. As a result, the acceptance cross-section of the bundle removal notch can be reduced in a simple and reliable manner. In a movement of the slide track in the opposite direction, for example, with a reduction in the distance between the slide track and the front of the bundle pickup, the first lever arm of the front of the bundle pickup swung away and so the pressure piece in the Bundelabnähme be withdrawn. As a result, the acceptance cross section of the bundle removal notch can be increased. It should be noted that in all variants of the bundle removal device, in which an adjusting lever is provided, the pressure piece can be integrated in the adjusting lever. Preferably, the pressure piece and the adjusting lever can form a materially homogeneous, monolithic unit, that is, for example, be produced in a common production process and be present in one piece.

The adjusting lever may be offset relative to the pressure piece. In this case, the adjusting lever can be arranged eccentrically with respect to a cross-sectional center plane on the bundle pickup. As a result, a material thickness of the bundle pickup adjacent to the offset part of the adjusting lever can be greater than in the case of bundle pickers with adjusting levers that are not offset relative to the preferably centrally acting pressure piece. This can result in greater stability of the bundle taker.

Preferably, the adjusting lever can be arranged flush with a transversely oriented to the adjustment of the bundle pickup outside or top of the bundle pickup on this.

It is particularly preferred if the bundle pickup has a pocket, within which the pressure piece and / or the adjustment lever are arranged. In particular, in a relative to the pressure piece offset or laterally offset lever then the pocket removed in the bundle taker not be so deep, which may favor the stability of the bundle customer.

It may furthermore be of particular importance for the reliability of the bundle removal device according to the invention if the front side of the bundle picker, which faces the bristle reserve provided in the bristle magazine, has an end face or outer contour which is closed 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 collector, which can result in a reduced filament distortion during the stuffing process. In this case, the pressure piece and / or the control device, in particular the adjusting lever, the crank lever, the sliding block, the wire roller and / or the adjusting wire, arranged behind the end face and / or be shielded from this. In this way, the bundle taker slides past the bristle supply in the bristle magazine with a homogeneous, uninterrupted and offset-free end face. The bristles provided inside the bristle magazine are thus presented with a uniform surface which is closed except for the bundle removal notch. This has the advantage that an undesired bristle distortion or filament distortion when feeding the bundles of bristles with the aid of the bundle pickup to the tamping tool of the brush production machine can be avoided.

It may 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 shielded from it. Thus, grooves, joints or other misalignment between the moving parts, which could affect a reliable and damage-free removal of bristles from the bristle magazine, can be avoided. The outwardly closed end face of the bundle pickup can shield the arranged inside the bundle pickup movable elements, such as the control device, the lever, the crank lever, the sliding block, the wire reel and / or the control wire. Thus, unwanted contact of these elements with the bristles in the bristle magazine of the brush making machine can be avoided. The closed end face of the bundle pickup can thus serve as a barrier between the bristle store held in the bristle magazine and the movable elements of the bundle pickup.

It is also possible that the front side of the bundle pickup is curved along a circular arc, ie the bundle pickup is present as a so-called circular arc divider or circular arc pickup.

Further, the bundle picker may be pivotable between the bundle receiving position and the bundle dispensing position about a preferably fixed pivot axis.

It should be noted that all of the aforementioned slide tracks can be arranged on a relative to the front of the bundle pickup, preferably motorized, adjustable holder. The slide tracks and / or the holders can be guided in a longitudinal guide relative to a frame of the brush manufacturing machine and / or the bundle removal device longitudinally displaceable. The object mentioned at the outset is also achieved by a brush manufacturing machine with the means and features of claim 21. According to the invention, in order to achieve the object in a brush manufacturing machine of the type mentioned in the introduction, it is provided that the bundle removal device is a bundle removal device according to one of the claims directed to the bundle removal device.

The solution of the above-mentioned object is achieved by the method described in claim 22 for removing a bristle bundle from a bristle supply and for transferring the bundle of bristles to a brush-making machine, in particular one according to claim 21, preferably using a bundle removal device according to one of claims 1 to 20, supported. In this method, it is provided that a decrease cross-section of a

Bundle removal notch is reduced after filling the bundle removal notch with a bundle of bristles and / or during movement of the bundle pickup between a bundle receiving position to a bundle delivery position and / or that the acceptance cross section of the bundle decrease notch is changed during filling of the bundle removal notch and / or that in the bundle decrease notch bristle bundles of the pressure piece is ejected from the bundle removal notch.

When the acceptance cross section of the bundle removal notch is reduced after filling the bundle removal notch, particularly while the bundle picker is on its way to the bundle delivery position, the bundle of bristles in the bundle removal notch can be compacted and the fill level of the bundle removal notch increased. To reduce the Acceptance cross-section can be inserted when using a bundle removal device according to the invention while the above-described pressure piece in the bundle removal notch. It may be useful in this context if the bundle removal device has a front counterpart which acts as a stop and extends along a Verstellweges of the bundle between the bundle receiving position and the bundle discharge position and the bundle removal notch is arranged opposite. This counterpart may be, for example, a baffle which is arranged to extend parallel to the front side of the bundle pickup. 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 better kept in the bundle removal notch and the degree of filling of the bundle removal notch can be increased.

If the bundle take-off cross section of the bundle take-off notch is changed when filling the bundle take-off notch, it is possible to influence the filling behavior. It is conceivable to deliberately increase or decrease the decrease cross-section of the bundle removal notch during the removal of bristles from the bristle supply of the bristle magazine. If the decrease cross-section during the removal of bristles from the bristle supply specifically changed, in particular increased, the bundle decrease notch is not in one shot, but homogeneously and optionally also filled slowly.

If the bundle of bristles located in the bundle removal notch is ejected from the bundle removal notch by means of the thrust piece, the thrust piece can assume a dual function and a separate ejection mechanism can be dispensed with. Embodiments of the invention are described in more detail with reference to the drawings. In a partially schematic representation:

In the following description of various embodiments of the invention, elements which correspond in their function receive matching reference numbers even in the case of deviating designs or shapes.

FIG. 1 shows a bundle removal device, denoted as a whole by 1, for a brush production machine 2. The bundle removal device 1 has a bundle pickup 3, which is shown in FIGS. 1 to 10 in different embodiments according to the invention.

Each of the bundle pickups 3 shown in the figures is provided with a bundle removal notch 6 on its front side 5 facing a bristle supply 4 in the position of use. to Removal of a bundle of bristles 7 from the bristle supply 4, which is held in a bristle magazine 8 of the brush making machine 2, the bundle taker 3 with its bundle removal notch 6 between a bundle receiving position and a bundle discharge position on the bristle supply 4 is moved past.

In the bundle pickup 3 shown in the figures, this is done by the bundle pickup 3 is pivoted past an open side 9 of the bristle magazine 8 along a circular arc. This is done in the bristle magazine 8 stockpiled bristles 10 in the bundle removal notch 6 of the bundle customer 3. This is done by existing on the bristle magazine 8 pushers 11, with which the individual bristles 10, which are stored in the bristle magazine 8, against the front side 5 of the bundle be pressed.

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

In order to change a decrease cross-section of the bundle reduction groove 6, the bundle removal device 1 has a movable pressure piece 15 which can be inserted into the bundle removal notch 6 as required and can be displaced there. In particular illustrate the figures 2 to 10, this pressure piece 15 is so arranged on the bundle removal device 1 and here specifically on the bundle pickup 3 that it is transverse to the longitudinal direction of the bundle removal notch 6 between a first transverse to the longitudinal direction of the bundle removal notch 6 extending edge 16, which is also upper Edge 16 may be designated, and a first edge 16 opposite the second edge 17 of the bundle removal notch 6, which may also be referred to as the lower edge 17, in the bundle removal notch 6 is displaceable.

The figures also show that at the bundle taker 3 between a first peripheral wall 16 adjacent the first peripheral wall 19 of the bundle removal notch 6 and a second edge 17 adjacent second peripheral wall 20 of the bundle removal notch 6, a material-free cross section 21 is formed by the pressure piece 15 from Direction of a rear side 22 of the bundle pickup 3 in the bundle removal notch inserted and slidable in the bundle removal notch 6. The material-free cross-section 21 of the bundle pickup 3 can also be referred to as a push-through opening for the pressure piece 15.

In this case, the pressure piece 15 is arranged so that it is centrally displaceable between the first edge 16 and the second edge 17 and in the bundle removal notch 6. The bundle pickup 3 comprises a guide 18, along which the pressure piece 15 guided in the bundle removal notch 6 is displaceable. Both above and below the pressure piece 15, there are peripheral walls 19 and 20, by means of which the bundle removal notch 6 is bounded laterally and on which a bristle bundle 7 located in the bundle removal notch 6 is supported. can be kept. The effect of fanning out the bristle bundles 7 within the bundle removal notch 6 described at the beginning can thus be reduced or even avoided. All of the pressure pieces 15 shown in the figures have one of the respective bundle removal notch 6 in the use position facing contact surface 23, which has a concave profile and concretely has the shape of a cylinder shell. The bundle removal device also has an adjusting device 24. This adjusting device 24 is adapted to move the pressure piece 15 in the bundle removal notch 6 to change the acceptance cross section of the bundle removal notch 6. A change in the acceptance cross section of the bundle removal notch 6 is possible from working stroke to working stroke of the bundle pickup 3. In addition, however, the adjusting device 24 is also adapted to the pressure piece 15 is also moved when located in bundle receiving position bundle pickup 3, located between the bundle receiving position and the bundle delivery position bundle pickup 3, in particular during this between these two positions, and located in bundle dispensing position bundle pickup 3 in the bundle removal notch 6 to move. This allows the implementation of the method described below.

FIGS. 1 to 4 now show a first embodiment of such a positioning device 24. According to FIGS. 1 to 4, the adjusting device 24 comprises a positioning wire 25. This positioning wire 25 is connected to the pressure element 15 connected and passed through this. For raising and lowering of the actuating wire 25 and thus for the displacement of the pressure piece 15 of the actuating wire 25 is moved with a free end of wire 26 which is bent to an eye or hook along a side facing away from the front 5 of the bundle 3 inclined surface 27. If the wire end 26 runs against the inclined surface, the adjusting wire 26 is raised. By raising the actuating wire 25, the pressure piece 15 is withdrawn from the bundle removal notch 6. By lowering the control wire 25, so when the free end of the wire 26 of the control wire 25 slips down on the inclined surface 27, the pressure piece 15 is moved into the bundle removal notch 6, whereby the decrease cross-section of the bundle removal notch 6 is reduced.

For winding and unwinding of the actuating wire 25, the adjusting device 24 in the embodiment shown in Figures 1 to 4 a wire reel 28. For winding and unwinding of the wire reel 28, the actuator 24 has a relative to the front side 5 of the bundle pickup 3 motor-adjustable slide track 29, guided in the slide track 29 sliding block 30 and a crank lever 31. The sliding block 30 is formed in the present case as a guide roller 30 and rotatably mounted on the crank lever 31. The wire reel 28 is rotatably connected to a sliding block 30 opposite end of the crank lever 31 with this. With an increase in the distance between the slide track 29 and the front 5 of the bundle pickup 3, the actuating wire 25 is wound by a corresponding rotation of the wire reel 28 on the wire reel 28. This is done by the linear motion that the slide track 29 takes place relative to the front side 5 of the bundle pickup 3, is converted via the crank lever 31 and the rotationally fixed connection between the crank lever 31 and the wire reel 28 in a rotational movement of the wire reel 28. This results in that the positioning wire 25, depending on the direction in which the slide track 29 is moved relative to the front side 5 of the bundle pickup 3, is wound up or unwound from the wire reel 28.

When the actuating wire 25 is wound onto the wire reel 28, the free wire end 26 is lowered on the inclined surface 27 or slides down this on the inclined surface 27. About the connection between the actuating wire 25 and the pressure piece 15, the movement of the actuating wire 25 is also transmitted to the pressure piece 15. In this way, when the setting wire 25 is lowered, that is, when the slide track 29 is moved away from the front side 5 of the bundle pickup 3, it is pushed into the bundle removal notch 6. When a distance between the slide track 29 and the front side 5 of the bundle pickup 3 is reduced, the positioning wire 25 is correspondingly unwound from the wire reel 28. In turn, the linear adjustment movement of the guide track 29 is converted into a rotational movement of the wire roller 28 via the crank lever 31, which causes the positioning wire 25 with its free wire end 26 to be pushed up along the inclined face 27, as a result of which the positioning wire 25 lifted and so the pressure piece 15 is retracted in the bundle removal notch 6 to increase the acceptance cross section of the bundle removal notch 6. According to FIGS. 1 to 4, the bundle pickup 3 of the bundle removal device 1 shown there has a wire guiding device 32. This wire guide device 32 also includes a guide groove 33, through which the actuating wire 25 is passed. The bundle pickup 3 has a pocket 34, within which the pressure piece: 15, the actuating wire 25, the crank lever 31 and the wire guide device 32 are arranged.

FIGS. 5 to 7 show a further embodiment of a bundle picker 3 according to the invention. It is provided that this comprises an adjusting device 24 for actuating the pressure piece 15, which comprises a one-armed adjusting lever 36 connected to the bundle pickup 3 via a hinge 35. With the help of this one-armed adjusting lever 36, the pressure piece 15 is displaceable in the bundle removal notch 6 to change the acceptance cross-section. In addition to the one-armed adjusting lever 36, the adjusting device 24 also includes a relative to the front side 5 of the bundle pick-up 3 by means of an actuator 48, ie by means of a drive and thus motorized, adjustable slide track 29th

The one-armed lever 36 is pivotally connected at a joint end 37 via the hinge 35 with the bundle pickup 3 and provided at a hinge end 37 opposite free lever end 38 with a guided in the slide track 29 sliding block 30, which is also a sliding roller 30 in this embodiment , The pressure piece 15 is arranged in a lever portion 39 between the hinge end 37 and the free end of the lever 38 or formed thereon. At an increase in the distance between the slide track 29 and the front of the fifth of the bundle pickup 3, the one-armed adjusting lever 36 is pivoted away from the front side 5 of the bundle pickup 3 and thus the pressure piece 5 is retracted in the bundle removal notch 6. In a reduction in the distance between the slide track 29 and the front 5 of the bundle pickup 3 of the one-armed lever 36 is pivoted to the front 5 of the bundle picker 3 and pushed so the pressure piece 15 in the bundle removal notch 6, so the decrease cross-section of

Bundle acceptance score 6 reduced.

FIGS. 8 to 10 show a further embodiment of a bundle collector 3 according to the invention, which can be used in a bundle removal device 1, as shown in FIG.

In this embodiment, an adjusting device 24 is provided, which has a two-armed adjusting lever 40, which is connected via a joint 35 to the bundle pickup 3 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 likewise comprises a guide track 29 which is motor-adjustable relative to the front side 5 of the bundle pickup 3. The two-armed adjusting lever 40 has the pressure piece 15 on a first lever arm 41 and a second on the other side of the joint 35 arranged second lever arm 42 guided in the slide track 29 sliding block 30. This sliding block 30 is expediently here as a sliding roller 30 before what his movement in the slide track 29 facilitates. At an increase in the distance between the slide track 29 and the front 5 of the Bundelabnehmers 3, the first lever arm 41 is pivoted in the direction of the front side 5 of the bundle pickup 3 and so the thrust piece 15 is inserted into the bundle removal notch 6 to reduce the acceptance cross-section.

The first lever arm 41 is pivoted away at a reduction in the distance between the slide track 29 and the front 5 of the bundle pickup 3 from the front 5 of the bundle pickup 3 and so the pressure piece 15 in the bundle decrease - score 6 retracted. As a result, the decrease cross-section of the bundle removal notch 6 can be increased.

FIGS. 5 to 10 illustrate that the pressure piece 15 is integrated in each case in the corresponding adjusting lever 36, 40. The sectional views according to FIGS. 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 of one piece. In the exemplary embodiment of the bundle pickup 3 shown in FIG. 10, it can be seen that the adjusting lever 36, 40 has been set down relative to the pressure piece 15. This means that there is a shoulder or step in the transition between the pressure piece 15 and the adjusting lever 36, 40, so that the adjusting lever 36, 40 eccentrically on the bundle taker 3 due to the centric arrangement of the pressure piece 15 in relation to a transverse extent of the bundle pickup 3 is arranged. As a result, the bundle pickup 3 according to FIG. 10 can have a greater material thickness in a section shown below the adjusting lever 36, 40. This promotes the stability of the entire bundle pickup 3. FIG. 10 further shows that the respective adjusting lever 36, 40 is arranged flush with an outer side 43 of the bundle picker 3 oriented transversely to the adjustment direction of the bundle pickup 3. Thus, the adjusting lever 36, 40 is not on the outside 43 of the bundle pickup 3 over.

According to the exemplary embodiments of different inventive bundle pickups 3 shown in FIGS. 7 and 10, these 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 a depth of these pockets 34 is at least as large as a thickness measured in cross-section of the respective adjusting lever 36, 40. It can be seen in particular from FIGS. 4, 6 and 9 that the front side 5 of the bundle receivers 3 shown there each have an end face 44 or outer contour which is closed except for the bundle removal notch 6. In this way, the bundle strip 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 within the bristle magazine 8 are thus presented with a smooth and uniform surface except for the bundle removal notch 6. This has the advantage that an undesired bristle distortion or filament delay when feeding the bristle bundles 7 by means of the bundle picker 3 to the stuffing tool 12 of the brush making machine 2 can be avoided. It is particularly advantageous that the pressure piece 15 and especially the respective adjusting lever 36, 40, with which the pressure piece 15 is actuated, arranged completely beyond the closed end face 44 and from this abge- is shielding. Thus, grooves, joints or other misalignment between the moving parts, which could affect a reliable and damage-free removal of bristles 10 from the bristle magazine 8, can be avoided. The outwardly closed end face 44 of the bundle pickup 3, the movable elements disposed within the bundle 3, such as the control device 24, the adjusting lever 36, 40, the crank lever 31, the sliding block 30, the wire reel 28 and / or the control wire 25 shield and prevent contact of these elements with the bristles 7. Thus, the end face 44 also serves as a barrier between the bristle supply 4 vorhal in the bristle magazine 8 and the movable elements of the bundle pickup third

All bundle pickups 3 shown in the figures have a front side 5 which is curved along a circular arc. Thus, the bundle takers 3 may also be referred to as a circular-arc pick-up or a circular-arc divider.

All of the bundle receivers 3 shown in the figures are pivotable about a pivot axis 45 between the bundle receiving position and the bundle dispensing position. The slide track 29 is arranged on a relative to the front side 5 of the bundle pickup 3 motor-adjustable holder 46. The motor-adjustable holder 46 is guided longitudinally displaceably in a linear guide 47 and can be displaced longitudinally in at least two directions by means of the actuator 48 relative to the front side 5 of the bundle pickup 3. The bristle magazine 8 of the brush-making machine 2 for the bristle stock 4 can be rotated or pivoted relative to a frame 49 of the brush-making machine 2. For example, to fill the bristle magazine 8 easier.

With the bundle removing apparatus 1 described above and the brush-making machine 2 described above, the following method of removing a bristle bundle 7 from a bristle stock 4 and transferring the bristle bundle 7 to the stuffing tool 12 of the brush-making machine 2 can be performed. It is provided that the decrease cross section of the bundle removal notch 6 is reduced after filling the bundle removal notch 6 with a bristle bundle 7. 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 degree of filling of the bundle removal notch 6 is increased.

Figure 1 shows that the front counterpart 50 of the bundle picking device 1 is a baffle bent parallel to the front side 5 of the bundle picker 3, extending 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 as an abutment surface for the bristle bundle 7 positioned in the bundle removal notch 6.

Furthermore, the bundle removal device 1 also has a rear counterpart 51, which has substantially the same construction as the front counterpart 50 and a second open side 52 of FIG Bristle magazine 8 closes, as long as 8 bristles 10 are to be removed len at the first open side 9 of the bristle magazine. The adjusting device 24 is further configured to change the acceptance cross section of the bundle removal notch 6 when filling the bundle removal notch 6 in order to influence the filling behavior. If the bundle taker 3 has reached the bundle delivery position in which the bundle removal notch 6 is located in the stuffing tool 12, the bristle bundle 7 located in the bundle removal notch 6 is ejected from the bundle removal notch 6 by means of the pressure piece 15 and thus transferred to the stuffing tool 12 for further processing.

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