Description

The invention relates to a brush stuffing machine for stuffing bristle bundles into bundle holes of a bristle carrier, in particular a brush body, with a stuffing tool and a slide guide, wherein the stuffing tool comprises a movable tool slide and an axially displaceable pusher tongue therein for stuffing in the bristle bundles, and wherein the tool slide is axially displaceable and rotatable about its longitudinal axis in the slide guide in order to fasten bristle bundles with fastening anchors oriented in different rotational positions in the bundle holes. Such brush-stuffing machines are used to manufacture brushes whose bristle bundles are secured in bundle holes by means of anchors. Various embodiments of such brush-stuffing machines are known from the prior art. DE 92 03 928 U1 discloses, for example, a brush stuffing machine and a device for measuring, if necessary adjusting, etc., a tongue of a stuffing tool of a brush stuffing machine. DE 41 14 297 C2 discloses a device for stuffing and anchoring bristle bundles in holes of a brush body, wherein the device comprises a stuffing tool and a feeding device for feeding fastening anchor strand material to the stuffing tool and is characterized in that the feeding device has a feed drive for the fastening anchor strand material with an electronically controlled positioning motor designed as a stepper motor or servo motor for the feed length variable, stepwise feeding of strand material with a stroke in the range between hundredths of millimeters and about 40 millimeters, and in that the fastening anchor strand material is guided in a loop shape in front of the feed drive. Particularly in the case of brushes whose bundle holes have rectangular or polygonal cross-sections and which are arranged in different orientations on the bristle carrier, it is necessary to insert a fastening anchor made from an anchor wire into the bristle carrier, matched to the orientation of the bundle hole. Various concepts are known from practice for inserting fastening anchors into the bundle holes of a bristle carrier at different rotational positions. In one concept, known from practice and generally proven, the brushes to be inserted are rotated relative to the insertion tool. However, to achieve sufficiently high process accuracy, comparatively large correction values ​​must be taken into account when rotating the brushes in an XY plane perpendicular to the insertion direction. This is relatively complex. The object of the invention is therefore to provide a brush stuffing machine of the type mentioned at the outset, which represents an alternative to the brush stuffing machines previously known from practice and which simplifies the production of stuffed brushes. This problem is solved by a brush stuffing machine of the type mentioned at the outset, which has the means and features of independent claim 1, which relates to such a brush stuffing machine. In particular, to solve the problem, a brush stuffing machine of the type mentioned at the outset is proposed, which has a deflection lever and a position-variable guide cam, wherein the deflection lever is directly connected to the tool slide and guided in the guide cam, so that the tool slide is rotated about its longitudinal axis by a change in the position of the guide cam. In this way it is possible to insert the fastening anchor supplied to the stuffing tool into bundle holes of a bristle carrier, in particular a brush body, in different rotational positions using the tool slide which can be aligned in different rotational positions. This rotation or pivoting of the tool slide can be carried out particularly precisely and easily if the deflection lever is oriented transversely or at right angles to the direction of impact of the ram tongue and / or to the direction of movement of the tool slide and / or is attached laterally to the tool slide. In order not to impede the working movements of the tool slide through the guide track, it may be advantageous if a length of the guide track, in particular a guide groove of the guide track in which the deflection lever is guided, corresponds at least to the length of a working stroke of the tool slide. In one embodiment of the brush stuffing machine according to the invention, the brush stuffing machine may be provided with a pivot bearing. This pivot bearing allows the guide carriage to be pivotally mounted relative to the tool slide. The pivot bearing can be arranged on a frame of the brush stuffing machine such that the guide carriage can be rotated and pivoted relative to the frame of the brush stuffing machine and also relative to the other elements of the brush stuffing machine arranged on this frame, in particular relative to the stuffing tool with the tool slide, in order to change its position. The pivot axis of the pivot bearing, around which the guide cam can pivot, can be aligned parallel to a longitudinal axis of the deflection lever. It can be advantageous if the pivot axis of the pivot bearing and the longitudinal axis of the deflection lever are coincident when the tool slide is positioned at a dead center of its movement, away from a tamping point where the bristle carrier to be tamped is located. This allows the position of the guide cam to be changed without affecting the rotation of the tool slide when the tool slide is at the rear dead center of its movement. Since the insertion of fastening anchors into the tamping tool typically occurs when the tool slide is at its rear dead center, it is both possible and advantageous to maintain a set pivot position of the guide cam when using a pivoting guide cam.This is particularly relevant when several bundle holes are to be filled with identically oriented fastening anchors. Regardless of the pivot position of the guide carriage, the tool slide will always return to its original rotational position when it reaches its rear dead center. This is the case provided that the pivot axis of the pivot bearing is coincident with the longitudinal axis of the deflection lever as soon as the tool slide reaches its rear dead center. If the orientation of the fixing anchors between two plugs needs to be changed, the guide cam can be adjusted as soon as the pusher tongue has been pulled out of the bundle hole of the bristle carrier. Thus, the return stroke of the tool slide can already be used to realign the tool slide with the help of the position-adjustable guide cam. To change the position of the guide cam, the brush stuffing machine can have a cam drive. The cam drive can be designed to allow linear or pivoting position changes of the guide cam. It is particularly advantageous if the cam drive includes a motor, especially a servo motor, for changing the position of the guide cam. The cam mechanism can include a push rod that is at least indirectly connected to the guide cam. A driving force from the cam mechanism, particularly its motor, can be transmitted to the guide cam via the push rod, thus allowing it to be adjusted. Particularly in the embodiment of the brush stuffing machine according to the invention with a pivotably mounted guide cam, it can be advantageous to arrange an intermediate element between the push rod and the guide cam. This intermediate element allows a linear push motion of the push rod to be converted into a pivoting motion of the pivotably mounted guide cam. Furthermore, to enable the conversion of the linear push motion of the push rod into a pivoting motion of the guide cam, it can be advantageous for the intermediate element to be pivotably mounted on both the guide cam and the push rod. To set the tool slide in its working motion, the brush stuffing machine can have a slide drive with a drive rod for the tool slide. The drive rod transmits a linear stroke motion between two dead centers to the tool slide, thus stuffing bristle bundles, along with fastening anchors, into bundle holes. In a particularly advantageous embodiment of the brush stuffing machine, the drive rod is connected to the deflection lever, which in turn is connected to the tool slide. This allows the drive motion of the drive rod to be transmitted via the deflection lever to the tool slide, thereby setting the tool slide in the desired working motion. To enable the transmission of the drive movement from the drive rod via the deflection lever to the tool slide even when the tool slide is in different rotational positions, it can be advantageous for the drive rod, particularly at its end facing the tool slide, to have a drive cam in which the deflection lever is guided by an intermediate section. The drive cam is preferably oriented transversely or perpendicularly to the guide cam. The intermediate section of the deflection lever is understood to be the section formed between a mounting end of the deflection lever on the tool slide and an end of the deflection lever guided in the guide cam. It should be noted that a guide groove of the drive cam can be oriented transversely or perpendicularly to a guide groove of the guide cam.This is to be able to tolerate different rotational positions of the tool slide relative to the drive rod and different angular positions of the deflection lever in the drive cam. The deflection lever can have a cam block at its end furthest from the tool slide. This cam block can, for example, be spherical, although cuboid or cube-shaped cam blocks may be preferable at the end of the deflection lever furthest from the tool slide. Such cuboid or cube-shaped cam blocks can have a larger contact area with the guide cam in which they are mounted in the operating position than is the case with spherical cam blocks. A larger contact area between the cam block and the guide cam can be advantageous in positively influencing wear and tear. In an intermediate section, such as the one mentioned earlier, the deflection lever can have a cylindrical cam block with which the deflection lever is guided in the drive cam. To enable at least line contact between the cylindrical cam block and the drive cam, it can be advantageous if a longitudinal center axis of the cylindrical cam block is oriented transversely or even perpendicularly to the longitudinal axis of the deflection lever. The brush stuffing machine can also have a ram drive with which the ram tongue can be moved through a ram channel of the tool slide in an alternating ram motion. For this purpose, the ram drive can have a ram rod connected to the ram tongue. Particularly when the ram tongue is arranged in the ram channel of the tool slide in a rotationally fixed manner relative to the tool slide, it can be advantageous if the ram rod is connected to the ram tongue via a rotary coupling. In this way, different relative rotational positions of the ram tongue with respect to the ram rod can be tolerated and compensated for. The wire material for manufacturing the fastening anchors can be fed to the tool slide of the brush stuffing machine by means of a wire feeding device. Typically, within the tool slide, the fed wire material is then cut to length into individual fastening anchors by means of a wire cutting device. During wire cutting, increased stresses can occur in the vertical direction and in the rotational or circumferential direction of the tool slide. To absorb the stresses occurring during wire cutting, it can be advantageous if the tool slide has at least one locking element, in particular a locking wedge, but preferably two locking elements, particularly offset from each other by 90°, and if the brush stuffing machine includes at least one correspondingly designed counter-locking element. This counter-locking element can, for example, be a locking notch into which the locking wedge of the tool slide can engage.The at least one locking element is preferably engaged with the counter-locking element when the tool slide is arranged in an anchor-receiving position on the previously mentioned wire feed device of the brush stuffing machine. In this way, the loads occurring during wire cutting in the vertical and / or rotational or circumferential direction of the tool slide can be absorbed via the locking connection thus created between the locking element and the counter-locking element. The tool slide can assume the anchor-receiving position at the rear dead center of its working movement or stroke. It can be particularly advantageous if at least one locking element is arranged on the slide guide. In order to accommodate loads acting in both the vertical direction and circumferential or rotational directions, it can be particularly advantageous if a counter-locking element is arranged on a top surface of the slide guide and a counter-locking element is arranged on a side surface of the slide guide offset by 90°. The brush stuffing machine can have a wire cutting device with a wire feed and a wire cutter. The tool slide can include a counter cutter associated with the wire cutter, wherein the mutually facing surfaces of the tool slide and / or the counter cutter on the one hand and of the wire cutter and / or the wire guide on the other hand are angled such that, after cutting a fed anchor wire for the production of fastening anchors, the tool slide is freely rotatable relative to the wire cutter and / or the wire guide. In this way, a collision of the tool slide with any of the elements of the wire feed device or wire cutting device is avoided when the tool slide rotates about its longitudinal axis. The invention will now be described in more detail with reference to exemplary embodiments. It should be noted that the invention is not limited to the exemplary embodiments shown in the figures. Further exemplary embodiments of the invention result from combining the features of one or more claims with each other and / or with one or more features of the invention discussed in this text. Figures 1 and 2 show, in a highly schematic representation, perspective views of a first embodiment of the brush stuffing machine according to the invention, in which a deflection lever guided in a linearly adjustable guide track can be seen laterally on the tool slide, with which a rotational position of the tool slide relative to its slide guide arranged in a housing can be changed. Figures 3, 4, 5, 6, 7 to 8 show perspective views of a further embodiment of a brush stuffing machine according to the invention, in which a guide track for changing a rotational position of the tool slide is arranged on a frame of the brush stuffing machine via a pivot bearing.Figure 9 shows a detail view of the tool slide depicted in the previous figures, showing a rear end piece of the tool slide with the attached deflection lever, a cylindrical cam block placed in an intermediate section of the deflection lever in its operating position, and another cam block, cuboid in shape and slidably guided by a flat contact in the associated guide track, attached to a ball head of the deflection lever in its operating position. Figures 10 and 11 show the detail of the tool slide shown in Figure 9, with the two cam blocks arranged on the deflection lever in their operating position. Figures 12, 13, 14 to 11 show the tool slide and its deflection lever in different rotational positions.15 highly schematic sectional views of the tool slide shown in the previous figures, wherein the section plane passes through the tool slide at a point where the anchor material is fed in to produce the fastening anchors. In the following description, elements that are identical in function will be given identical reference symbols even if they differ in design or shape. Figures 1, 2, 3, 4, 5, 6, 7 to 8 show different embodiments of a brush stuffing machine, designated in its entirety by 1. The brush stuffing machines 1 shown in the figures are used for the production of brushes. It is provided that, with the aid of the brush stuffing machines 1, bundles of bristles 2 are stuffed into bundle holes 3 of a bristle carrier 4. The bristle carrier 4 shown in the figures is a brush body. Each of the brush stuffing machines 1 shown in the figures comprises a stuffing tool 5 and a slide guide 6. The stuffing tool 5 has a movable tool slide 7 which includes an infeed channel 8. An axially displaceable infeed tongue 9 for stuffing the bristle bundles 2 is arranged in the infeed channel 8. The tool slide 7 is mounted in the slide guide 6 so as to be axially displaceable and rotatable about a longitudinal axis. This is done to secure bristle bundles 2 in the bundle holes 3 with fastening anchors 10 oriented in different rotational positions. Each of the brush packing machines 1 shown in the figures has a deflection lever 11 and a position-adjustable guide cam 12, wherein the respective deflection lever 11 is directly connected to the tool slide 7 and guided in the guide cam 12. This allows the tool slide 7 to be rotated about its longitudinal axis by changing the position of the guide cam 12. In this way, bristle bundles 2 with fastening anchors 10 oriented in different rotational positions can be anchored in the bundle holes 3 of the brush body. The deflection lever 11 is oriented perpendicular to the direction of impact of the ram tongue 9 through the tool slide 7 and also perpendicular to the direction of movement of the tool slide 7. Furthermore, the deflection lever 11 is attached to the side of its respective tool slide 7 at one end. The length of the guide track 12, in which the deflection lever 11 is guided, corresponds at least to the length of a working stroke traversed by the tool slide 7 during operation of the brush filling machine 1. It should be noted that the tool slide 7 performs an alternating movement, limited by two dead centers, during operation of the brush filling machine 1. The working stroke corresponds to the distance traveled by the tool slide 7 in one direction during a single stroke. The guide track 12 has, or defines, a guide groove 13 in which the deflection lever 11 is guided. In the embodiment of a brush filling machine 1 shown in Figs. 3, 4, 5, 6, 7 to 8, the machine has a pivot bearing 14. By means of the pivot bearing 14, the guide cam 12 is pivotably mounted relative to the tool slide 7 and is arranged on a frame 15 of the brush filling machine 1. Examples of the different rotational positions of the tool slide 7, which can be assumed with the aid of the pivotally mounted guide cam 12, are shown in the individual figures 3, 4, 5, 6, 7 to 8. Intermediate positions of the guide cam 12 are also possible. Figures 3, 5 and 7, in which the tool slide 7 is arranged at its rear dead center, illustrate that a pivot axis 16 of the pivot bearing 14, about which the guide cam 12 of this brush stuffing machine 1 can pivot, is parallel to a longitudinal axis of the deflection lever 11 and is also coincident with the longitudinal axis of the deflection lever 11 as soon as the tool slide 7 is at its rear dead center. A comparison of Figures 3, 5, and 7 clearly illustrates the associated advantage. If the pivot axis 16 of the pivot bearing 14, in the end position shown there, is congruent with the longitudinal axis of the deflection lever 11 at the rear dead center of the tool slide movement of the tool slide 7, the position of the guide cam 12 on the pivot bearing 14 can be changed without affecting the rotational position of the tool slide 7 in that position. Regardless of the rotational position of the guide cam 12, the deflection lever 11, and thus also the tool slide 7 connected to it, always assumes the same position and rotational orientation relative to the slide guide 6 at the rear dead center. This can simplify the feeding of anchor wire for the production of fastening anchors 10 within the tool slide 7. To move the guide cams 12 into their different positions, each of the brush filling machines 1 is equipped with a cam drive 17. In the embodiment of the brush filling machine 1 according to Figs. 1 and 2, this cam drive 17 is configured for a linear change in the position of the guide cam 12. In the embodiment of the brush filling machine 1 shown in Figs. 3, 4, 5, 6, 7 to 8, the cam drive 17 used there is configured for pivoting the position of the guide cam 12 installed there. Each of the cam drives 17 includes a motor, which in this case is designed as a servo motor 18, for changing the position of the respective guide cam 12. Each of the cam drives 17 shown in the figures has a push rod 19. This push rod 19 is at least indirectly connected to its associated guide cam 12 and serves to transmit a drive force from the cam drive 17 to the guide cam 12. In the embodiment of the brush stuffing machine 1 shown in Figs. 3, 4, 5, 6, 7 to 8, an intermediate element 20 is arranged between the push rod 19 and the guide cam 12. This intermediate element 20 is pivotably mounted on both the push rod 19 and the guide cam 12. It serves to convert the linear push motion of the push rod 19 into a pivoting motion of the pivotally mounted guide cam 12.The rotatable mounting of the intermediate element 20 on both the push rod 19 and the guide cam 12 allows for compensation of any change in angle between the push rod 19 and the guide cam 12 that occurs when the position of the guide cam 12 is changed. Each brush filling machine 1 has a slide drive 21. The slide drive 21 serves to move the tool slide 7 alternately between its two dead centers. For this purpose, each slide drive 21 has a drive rod 22 for the tool slide 7. The drive rod 22 is connected to the deflection lever 11 of the respective brush filling machine 1. This connection is such that a drive movement of the drive rod 22 is transmitted to the tool slide 7 via the deflection lever 11. As a connecting element between the drive rod 22 and the deflection lever 11, the drive rod 22 has a drive cam 23 at its end facing the tool slide 7, in which the deflection lever 11 is guided by an intermediate section 24. The drive cam 23 is aligned with its guide groove at a right angle to the guide groove 13 of the guide cam 12. The deflection lever 11 has a cam block 25 at its end facing away from the tool slide 7. If this cam block 25 is spherical, as shown in Figs. 1, 2, 3, 4, 5, 6, 7 to 8, there is point-like or line-like contact between the guide cam 12 and the cam block 25. This can be disadvantageous due to wear. Therefore, the cam block 25 can also be cuboid, as shown in Figs. 9, 10 to 11. Here, the cam block 25 is placed on a mounting ball 26 at a free end of the deflection lever 11. The side surfaces of the cuboid cam block 25 can then bear fully against the limiting walls of the guide groove 13 in the guide cam 12. The use of a mounting ball 26 to attach a cam block 25 can be advantageous, as it allows for compensation of different angular positions of the deflection lever 11 relative to the guide cam 12. The cam block 25 forms a ball joint with the mounting ball 26. The mounting ball 26 acts as a ball head, which, in its operating position, engages in a socket formed on the cam block 25. This allows the cam block 25 to assume different angular positions relative to the deflection lever 11. Two different angular positions are shown, for example, in Fig. 10 and Fig. 11. Figures 9, 10 to 11 further show that the deflection lever 11 has a cylindrical cam block 27 in the aforementioned intermediate section 24, by which the deflection lever 11 is guided in the drive cam 23. To allow line contact of the cam block 27 in the drive cam 23 and angular tolerance, a longitudinal center axis of the cylindrical cam block 27 is aligned perpendicular to the longitudinal axis of the deflection lever 11 in its operating position. In its operating position, the deflection lever 11 is inserted through a bore 27a in the cam block 27. Each of the brush stuffing machines 1 shown in the figures is also equipped with a pusher drive 28. With the aid of the pusher drive 28, the pusher tongue 9 can be moved alternately back and forth through the tool slide 7 to stuff fastening anchors 10 together with bristle bundles 2 into bundle holes 3 of a bristle carrier 4. To transmit a drive force from the pusher drive 28 to the pusher tongue 9, the pusher drive 28 has a pusher rod 29. The pusher rod 29 is connected to the pusher tongue 9 via a rotary coupling 30. In this way, rotation of the pusher tongue 9 relative to the pusher drive 28 and its pusher rod 29 can be tolerated. Such rotation occurs because the pusher tongue 9 is arranged in a rotationally fixed manner in the rotatable tool slide 7. Figures 1, 2, 3, 4, 5, 6, 7 to 8 show that the tool slide 7 has two locking elements 31 in the form of locking wedges. These are arranged offset from each other by 90° and serve to absorb forces occurring during the cutting of the anchor material, which act in the vertical and rotational direction of the tool slide 7. The brush filling machine 1 has two corresponding counter-locking elements 32 in the form of locking notches. The two locking elements 31 are engaged with the counter-locking elements 32 when the tool slide 7 is arranged in an anchor receiving position on a wire feed device 33 of the brush filling machine 1. The tool slide 7 is shown in this anchor receiving position, for example, in Figures 1, 3, and 7.The two notch-shaped locking elements 32 are arranged on the slide guide 6, specifically on a top surface and a side surface of a housing 34 containing the slide guide 6. A first locking element 32 is located on a top surface 35 of the housing 34 of the slide guide 6, while a second locking element 32 is located on a side surface 36 of the slide guide 6 or its housing 34, offset by 90°. The brush-stuffing machines 1 shown in the figures each also include a wire-cutting device 37, which comprises a wire feed 38 and a wire knife 39. The tool slide 7 in turn has a counter-knife 40, which is associated with the wire knife 39. A section through the plane of the wire-cutting device 37 is shown in Figures 12, 13, 14 to 15 with the tool slide 7 in different rotational positions. The surfaces of the tool slide 7, the counter blade 40, the wire cutter 39, and the wire guide 38 facing each other are angled such that, after cutting a supplied anchor wire 41 to produce a fastening anchor 10, the tool slide 7 can rotate freely relative to the wire cutter 39 and the wire guide 38. The effect of the angled surfaces relative to each other is clearly illustrated in the different views shown in Figures 12, 13, 14 to 15. A collision between the tool slide 7 and the elements of the wire cutting device 37 is prevented by the angled orientation of the surfaces of the aforementioned components. All Figures 1, 2, 3, 4, 5, 6, 7 to 8 further show that each of the brush stuffing machines 1 depicted therein also has a bundle-dividing device 42. With this bundle-dividing device 42, individual bristle bundles 2 can be removed from a bristle magazine 43 containing a supply of loose bristle filaments. The bundle-dividing device 42 comprises a circular arc divider 44 equipped with a bundle-dividing notch. The circular arc divider 44 is moved in an alternating, pivoting motion past an open front face of the bristle magazine 43 in order to remove an individual bristle bundle 2 from the supply of loose bristle filaments with its bundle-dividing notch.After the removal of a bristle bundle 2, this is transferred to the stuffing tool 5 of the brush stuffing machine 1 with the help of the circular arc divider 44 and, together with a cut-to-length fastening anchor 10, is grasped by the pusher tongue 9 and stuffed into a bundle hole 3 of the bristle carrier 4 held on a holder 45. The invention relates to improvements in the field of brush filling machines. For this purpose, the brush filling machine 1 is proposed, which has a tool slide 7 rotatable about its longitudinal axis. To rotate the tool slide 7 about its longitudinal axis, the brush filling machine has a deflection lever 11, which is attached directly to the tool slide 7 on one side and mounted in the position-adjustable guide track 12 of the brush filling machine 1 on the other. By changing the position of the guide track 12 relative to the tool slide 7, the rotational position of the tool slide 7 can be changed by means of the deflection lever 11.
