Description

Brush packer and packing tongue

Technical Field

The invention relates to a brush stuffer having a stuffing tool which has a tip, can be pivoted by means of its tip about a first axis between a tuft receiving position and a stuffing position, and which has a guide in the tip for a tongue which stuffs an anchor together with the tufts along the guide into a bristle carrier which forms at least part of the finished brush. Furthermore, the invention relates to a packing tongue for a brush packer according to the invention.

Background

Such a brush packer is known from EP 1803372B 1. In the brush stuffer, there is a tuft picker pivotable about a vertical axis and a stuffing tool also pivotable about a vertical axis. The tuft picker separates the tufts from the bristle magazine and transfers them to a tamping tool directly behind the tip. In the tip there is a guide for the tongue, so that the tongue-received bristle tufts, together with the anchor, are guided along the guide to the bristle carrier, which forms at least part of the finished brush, and are pushed into the opening in the bristle carrier.

The anchor can be a metal sheet or a wire loop.

The tamping tool is pivoted in the direction of the bristle carrier after receiving the separated tufts, wherein the tongues take part in the pivoting movement and during the pivoting movement have or after reaching the tamping position entered deeper into the tips in order to subsequently push the tufts together with the anchor into the bristle carrier.

Not only does the tamping tool move along with the curved guide in the tip, but also the tongue moves over the circular segment.

Alternatively, a linearly movable tamping tool is available with a linear tongue which is moved back and forth in a translatory manner, as is known from DE 4324249 a 1.

Such brush pluggers must have faster cycle times.

Disclosure of Invention

The object of the present invention is to improve a brush stuffer of the type mentioned at the outset such that it can be operated with a faster cycle time.

The brush stuffer according to the invention has a stuffing tool having a point, which is pivotable about a first axis between a tuft receiving position and a stuffing position, and which has a tongue in the point guiding the anchor together with the tufts along the guide into the bristle carrier. The brush stuffer according to the invention proposes that the guide of the tongue runs linearly in the tip and that the front end of the tongue performs a linear impact movement in the stuffing position relative to the stuffing tool. The tongue has a guided front section, which is adjacent to the bristle carrier and which, when fed into the filling position, is supported in the guide of the tip, and a rear section on the drive side, wherein the cross section of the rear section is larger than the cross section of the front section, preferably by at least 2 times, in particular by at least 3 times. The rear section projects partially into the linear guide in each position of the tongue and of the tip. Thereby, despite the increased friction in the guide, the harder section of the tongue projects into the guide. On the other hand, the section which is more stable and has a uniformly larger cross section is thereby located outside the guide(s), so that no guide need be present here. The rear section is therefore not guided to the end section on the drive side, in order to be bent only in said section during the feed movement and the subsequent return movement of the tongue.

In the prior art, there is always the rule that the movement of the tip defines the movement of the tongue in the front section of the tongue. The movement change should not be carried out in the region of the tip in order not to additionally load the thin tip in this region and in particular in order to be able to easily and more reliably determine and form a movement path. That is to say, when the tip moves on a circular track, the front end of the tongue should also continue said circular track if the tongue moves away from the guide in the tip. Conversely, if the tip itself is moved back and forth linearly, the tongue should move out of the guide in the tip linearly. While in the prior art the tongue is shaped like a circular segment during the pivoting movement of the tip and the guide in the tip likewise shows a circular segment, in the present invention, a linear impact movement is achieved by the linear guide despite the pivoting movement of the tamping tool. The pivoting movement of the tamping tool is advantageous compared to a linear movement, since a reversible pivoting movement can be realized with less effort, with high precision and in particular at great speed. However, since the linear movement is performed by the tongue on its front end, the movement can also be performed faster. By the linear impact motion, the friction with respect to the guide portion is reduced. Furthermore, the movement of the tufts together with the anchor is linear throughout the final part of the movement, which results in a smaller space requirement of the tip and the front end of the tongue. If the tongue, in the final angle of its movement, extends also on the circular path until the insertion, then an unfavorable lateral movement component occurs during the pressing-in of the tuft, which loads the end of the tip and causes additional friction in the guide. By means of the increased cross section, in the spring-elastic tongue, a region is realized which is subject to bending, so that the tongue has an increased service life.

In general, the bristle carrier can be, for example, a thin plate provided with openings, which is then split together with the rest of the brush body into a common brush body, or the bristle carrier can also be the brush body itself.

The cross section of the front section of the tongue is identical in particular in its longitudinal extent and/or the cross section of the rear section of the tongue is identical in its longitudinal extent, which enables a simpler manufacturability.

Between the front section and the rear section, there can be a transition section in which a specific continuous transition of the cross sections takes place, in particular in which the cross sections transition into one another with a radius. Thereby, notch stresses, which are present in the indentation formed between the front section and the rear section, should be avoided.

Alternatively or additionally, the fastening section adjoins the rear section at the drive-side end and forms the drive-side end. Here, for example, recesses and/or projections in the width can be present in order to simplify the fastening of the drive side.

The rear section projects partially into a second guide spaced apart from the tip in each position of the tongue and in each position of the tip.

The second guide portion can extend linearly or in a circular arc about the pivot axis of the pivot drive. One possibility is that, similar to the guidance in the tip, the tongue is guided on both sides and also on the upper and lower part. For example, the guide groove can be formed in the upper or lower part and the parts above or below it can be flat or likewise the guide groove is provided with a section such that the second guide is completely closed. Alternatively, the tongue can run along the roller on at least one side and be guided by it. In this embodiment, the rear section projects into a second guide spaced apart from the tip and thus from the guide in the tip, whereas the front section also projects into said second guide.

A variant of the invention provides that, although the rear portion projects partially into the second guide in each position of the tongue and of the tip, it is not guided to the fastening portion on the drive side, in order to be bent only in the unguided region during the feed and return movement of the tongue.

The second guide spaced apart from the tip can be a linear guide aligned with the guide in the tip, i.e. it lies in one plane therewith. The second guide spaced apart from the tip can also be formed in a base mechanically rigidly coupled to the tip. Alternatively, the two guides, in the transition without a distance, are common guides to one another.

In the second guide, a transition between the front section and the rear section is preferably always present, i.e. independently of the position of the tip and of the tongue. This is particularly advantageous since the sections are inevitably critical in terms of strength and long-term stability.

The tongue should be a one-piece uniform thickness strip of spring steel. The spring steel band makes it possible to drive the tongues by means of a pivot drive without great effort. As the tongue moves, different areas of the tongue move differently, i.e. along the circular track and along the linear guide, as described above.

The tongues can be actuated by a preferably own pivot drive, for example by: there is a pivot arm of its own for driving the tongue. This means that the tongue is moved on the one hand along a circular arc path in the region of its driven end and on the other hand linearly in the region of the guide in the tip.

The guide for the tongue can be placed on a pivoting arm of the tamping tool.

Preferably, the axis of the pivot arm of the tongue is also the first axis.

The tamping tool can be driven by at least one cam and/or the pivoting drive can be driven by at least one cam. Such cam drives are characterized by a high mechanical stability. One possible variant provides that the cams of the pivoting drive for the tamping tool and for the tongues are set in rotation by the same camshaft. Thereby, forced synchronization can be achieved in a very simple manner.

Alternatively, it is also possible for the pivot arm for the tamping tool and for the tongue to be pivoted by its own electric servomotor. The control of the servomotor ensures synchronization of the movement of the pivot arm.

The distance of the front end of the tip from the first axis is at least 200mm, in particular at least 300mm, so that the movement of the guide takes place over an extremely large arc radius. The considerable pivot radius also ensures that the pivot angle for the pivot arms between the tuft receiving position and the tamping position is very small, for example between 2 ° and 5 °. The small pivot angle is however sufficient to perform a complete stroke of the tamping tool.

The feed stroke of the tamping tool can be, for example, only 15-20mm, measured between the tuft receiving position and the tamping position at the front end of the tip. The small stroke is also used for high cycle times. In the prior art, a corresponding stroke of 25mm is normal. Thus, the stroke is greatly reduced in percentage.

The guide in the tip can run substantially straight, for example horizontally. The horizontal extension in relation to the plugging position simplifies the orientation of the components relative to one another and in particular the production of the components, since the linear guide can be produced considerably more simply than in the case of a circular arc.

The first axis can be a horizontally oriented axis, whereas in EP 1803372B 1 the central axis is vertically oriented.

If the bristle carrier has an elongated configuration, the longitudinal direction of the bristle carrier is oriented, in particular, parallel to or at a slight angle (i.e. 15 ° -25 °) with respect to the first axis. The pivoting movement of the tamping tool thus lies in a plane perpendicular to the longitudinal direction of the bristle carrier.

The brush stuffer according to the invention can be constructed without so-called tuft squeezers. The tuft presser is in the prior art a separate part located before the tip, which presses the tufts anchored in the bristle carrier aside when the next tuft is stuffed next to the tufts anchored in the bristle carrier. By means of the brush stuffer according to the invention, in which the tip itself performs a sinking movement and squeezes the stuffed bristle bundle, no separate squeezer of this kind is required, so that the brush stuffer according to the invention is of simpler construction and also less complex, whereby higher cycle times can be achieved.

The brush stuffer according to the invention optionally comprises a tuft picker which delivers the separated tufts to the stuffer tool, in particular in a horizontal plane.

The tuft picker can be a plate-like circle segment or a rotating disk which can pivot or rotate about a vertical axis.

The tamping tool can thus be oriented relative to the bristle carrier such that the front end of the tip, viewed in the direction of the first axis, has a movement from the tuft receiving position into the tamping position which has a component oriented vertically downwards. This means that the end of the tip moves from the upper incline downwards towards the bristle carrier, i.e. sinks slightly, whereby the already packed bristles are pressed apart.

An inclined surface, which is optionally provided on the tip, more precisely in the region of the end on the underside thereof, is oriented obliquely upward toward the end and forms a deflection surface for the bristle tufts which have been packed. Of course, the upper side can also be inclined towards the end, so that the tip tapers towards the end.

A drum can be used, for example, which rotates about a vertical second axis and has holders for a plurality of bristle carriers, which are opposite the tamping tool. The bristle carrier located in the holder of the drum opposite the tamping tool can thus be tamped directly. This is therefore a rotary tool which can occupy a plurality of positions.

The invention also relates to a tongue for a brush stuffer according to the invention, i.e. a stuffing tongue. The tongue is a spring steel band of uniform thickness, with a front section, which is close to the bristle carrier, for bearing in a guide in the tip, and a rear section of the drive side, wherein the rear section has a cross section which is greater than the cross section of the front section, wherein the tongue has a thickness of 0.2mm or more.

The tongue has a fastening section on the drive-side end, which fastening section has a recess and/or a projection in the width for fastening on the drive side.

The tongue has two opposite longitudinal edges which define the width of the spring steel strip in length, wherein one of the longitudinal edges runs completely straight and the other longitudinal edge has a setback in order to form a transition between the front section and the rear section. Said variant allows the use of a simple punching tool for the tongues. Furthermore, the tongue is guided on one of the lateral edges, which is possible by a straight edge run.

It is emphasized that the tongue according to the invention can also have all the features described above in connection with the stuffer machine, either individually or in combination, as, also conversely, the stuffer machine can have the characteristics and features mentioned in connection with the tongue according to the invention.

FIG. 3 shows a schematic side view of the tamping tool according to FIG. 1, with the tongues in the tuft-receiving position, and

fig. 4 shows a side view of a variant of a tongue according to the invention for use in the brush-stuffing device according to the invention according to fig. 1 and 2.

Detailed Description

Fig. 1 shows a brush stuffer having: a drum 10 having a plurality of holders for brushes; a tamping tool 12; a brush hair storage 14; tuft picker 16 and tongue 52 for stuffing. Furthermore, there is a delivery device 18, symbolically shown by an arrow, for a so-called anchor 20, for example in the form of a wire loop or a metal sheet.

In the brush stuffer, the bristle carrier 22, which is then part of the finished brush, for example a thin plate with openings or a bristle carrier 22 in the form of a complete brush body, is stuffed as shown in fig. 1.

The drum 10 is designed as a rotating holding tool, on which a plurality of holders for bristle carriers 22 are accommodated on a carrier 26 which can rotate about an axis 24, said bristle carriers being fed to the carrier 26 at specific locations and removed and being filled in one location.

The axis 24 is preferably horizontal or slightly angled (15 ° -25 ° relative to the horizontal), or the elongate bristle carrier 22 is oriented with its longitudinal direction in a horizontal direction or likewise slightly angled to the axis 24.

In the filling movement shown subsequently, the bristle carrier 22 to be filled is moved in a vertical plane along two axes by the movement of the carrier 26, so that the opening to be filled subsequently in the bristle carrier is always opposite and aligned with the next bristle strand guided in.

The bristle magazine 14 includes a mechanically pre-tensioned store with aligned adjacent bristles 28. The tuft picker 16, which is pivotable about a vertical axis 30, moves along the magazine with the bristles 28 and picks up tufts, which is achieved by: the tuft extractor 16 has a cutout 32 on its outer edge running along, which cutout is filled by the bristle tufts, wherein the tuft extractor comprises a plate-like circular segment.

The tamping tool comprises a tip 34 having a front end 36 which is pivoted about a preferably horizontal first axis 40 between a tuft receiving position and a tamping position shown in fig. 1. The tip 34 thus moves on a circular orbit.

In the packed position, the end 36 can contact the bristle carrier 22 or be completely close to its surface.

In the tuft receiving position, end 36 is on dot-dash line 44. The stroke formed between the tuft receiving position and the stuffing position is only between 15mm and 20 mm.

The tamping tool 12 comprises a pivoting arm 46, which is coupled on one end with a support 48. The support 48 is a support corresponding to the axis 40.

The opposite end of the pivot arm 46 carries a base 50 which transitions into the tip 34.

A guide 56, which is schematically visible in fig. 3 and is slit-shaped in cross section, is provided in the tip 34. The guide 56 in the tip 34 extends linearly.

The base 50 has on its upper side a groove 51 which is designed as a guide groove, more precisely for a tongue 52 shown in fig. 2, which moves back and forth relative to the base 50 according to the double arrow in fig. 2. The tongue 52 is guided on the base 50 in such a way that: a cover 57 (see fig. 3) is placed on the base, said cover closing upwardly a second guide 58 which is present at a distance from the tip and which can likewise be designed linearly and in the same plane as the guide 56.

Alternatively, the second guide portion 58 may also be arc-shaped.

The tongue 52 is band-shaped and elongated, and has a uniform thickness.

In fig. 2 and 4, the tongue 52 according to a second, different embodiment is again shown separately. The following applies for both embodiments: the tongue 52 always has a guided front section 53 in which it has a relatively narrow cross section and in which it is guided in the region of the tip 34 and the base 50 in the first and

second guides

56 or 58. Furthermore, the tongue 52 has, however, a rear portion 55 adjacent to the front portion, which in the embodiment according to fig. 2 is of relatively short design in the longitudinal direction, but is significantly longer in the embodiment according to fig. 4, wherein the cross section of the rear portion 55 is generally larger than the cross section of the front portion 53, preferably by a factor of at least 2, in particular by a factor of at least 3. Common to both embodiments is that the cross section of the tongue 52 remains constant over the length of the front section 53 and the rear section 55, respectively.

The one-piece tongue 52 is a spring steel band which is of uniform thickness, measured in the view according to fig. 3 at least 0.2 mm. In contrast, in the plane of the drawing, the tongue 52 is significantly wider, as can be seen in fig. 2 and 4.

Between the front section 53 and the rear section 55, there is a so-called transition section 90, in which the cross-sectional transitions in a continuous manner. In the embodiment according to fig. 2, the front section 53 runs centrally, as seen in the longitudinal direction, with respect to the rear section 55, so that an axis of symmetry is produced in the longitudinal direction. The wider rear section 55 then merges with a radius into the narrower front section 53 in the region of the transition section 90.

In the embodiment according to fig. 2, the front section 53 extends in the first and

second guide

56 or 58 in each position of the tongue 52.

The rear portion 55 does not reach into the second guide 58 in the tongue 52 shown additionally on the top alone, since the rear portion 55 is too short in the longitudinal direction. If the section 55 is longer, however, as indicated by the broken line in fig. 2, it projects partially, i.e. by its front end section, into the guide 58 explained below with reference to fig. 3.

The rear fixed end 92 of the tongue 52 is moved along an arc of a circle by the pivot drive 82. The pivot drive 82 includes a pivot arm 84 having an axis coincident with the first axis 40.

The tongue 52 according to fig. 4 can be produced more simply and works better than the tongue according to fig. 2. In the following, only the differences with the tongue according to fig. 2 are described, all other features being identical with the tongue according to fig. 2. The front section 53 is not centered relative to the rear section 55, but rather extends as an extension on one of the two

longitudinal edges

94, 100. This means that the longitudinal edge 94 is formed as a continuous straight edge in the region of the front section 53, the transition section 90 and the rear section 55. Only in the region of the fastening section 92 is a projection 96 in width, which serves for the separation and fastening of the tongue 52 on the driver. A groove 98 is also provided for the same purpose.

The opposite longitudinal edge 100, although being straight relative to the longitudinal edge 94 in the region of the front section 53 and the rear section 55, respectively, is present in the region of the transition section 90. Here, the indentations do not form any corners, to be precise punctiform recesses 102 or radii 104 without recesses, which are shown as interrupted lines.

In contrast to the embodiment according to fig. 2 (except for the tongue 52 in fig. 2, which is modified by a broken line), in this embodiment the wider section 55 projects into the guide 58 in each position of the tongue 52 and the tip 34. Fig. 3 shows an unguided region 106 of the rear section 55, in which, during operation, preferably only bending of the tongue 52 takes place.

An insertion opening 60 (see fig. 1) is provided between the tip 34 and the base 50, which opening is open to the side and into which the tufts of bristles can be introduced by the tuft extractor 16 and the anchor 20 by the delivery device 18.

The front end 54 of the tongue 52 can be pushed through the tip 34 and here bend the separated bristle strands and push with the anchor 20 into the opening of the bristle carrier 22.

The end 36 of the tip 34 is spaced from the first axis 40 by a distance of at least 200mm, preferably at least 300 mm.

The pivoting angle between the tuft receiving position and the stuffing position is preferably at most 3 °, i.e. very small.

The pivot arm 46 is pivoted back and forth through the aforementioned 3 ° by means of a servomotor or by means of a mechanical device shown below.

Each

pivot arm

46, 84 is driven by a

cam

68A, 68B or 70A and 70B. The cams are mounted on a common camshaft 71. The camshaft 71 is driven by a motor. The camshaft is shown schematically in fig. 1.

Cams 68A and B and 70A and B are configured as side-by-side disk pairs with an outer periphery other than circular.

For the cam 68A there is a roller 64 on the pivot arm 46, the cam 68A can be in contact with the roller. With corresponding contact, the cam 68A presses the pivot arm 46 counterclockwise toward the tamping position.

The cam 68B has a roller 66 on the second arm 62 of the tamping tool, with which the cam can come into contact.

The cam 68A is thus responsible for the counterclockwise, i.e. in the plugging direction, pivoting movement of the plugging tool 12, whereas the cam 68B, via its associated roller 66, is responsible for the clockwise pivoting movement of the plugging tool.

Alternatively, it is also possible to operate only with the cam 68A or B and, furthermore, to permanently press the

roller

64 or 66 against the one cam via a spring. However, the two cams 68A and B are advantageous in the case of a higher cycle rate.

Corresponding embodiments of

cams

70A and 70B are also provided for the drive pivot arm 84, as is corresponding for the drive pivot arm 46. Cam 70A contacts roller 73, for example, on arm 75 which is coupled to pivot arm 84.

On the pivot arm 84, hidden in the figures, there is an associated roller corresponding to the roller 6, which can be in contact with the cam 70B. Thus, via

cams

70A and 70B, pivot arm 84 for tongue 52 is driven in both directions.

The operation of the brush stuffer is briefly described below.

In the tuft receiving position, the tuft picker pivots the extracted tufts in a horizontal plane into the insertion opening 60. In this position, the tongue 52 is moved back so that it is exposed to the insertion opening 60 for the tuft picker. That is to say, the resetting movement causes the tongue 52 to temporarily leave the guide 56 and to be accommodated only in the guide 58. The delivery device 18 also delivers the anchor 20 to the introduction opening 20 (see fig. 2). Subsequently, the tamping tool 12 is pivoted relative to the bristle carrier 22.

It can be seen in fig. 3 that the tip 34 moves forward and slightly vertically downward in a slight sinking motion from the shown tuft receiving position into the tamping position.

In the region of the end, a bevel 71 is formed on the underside of the tip 34, which bevel faces the end 36 and is directed upward and presses the already packed bristle bundles 72 downward, so that for the subsequent packing process there is no risk of the tongue 52, the transported bristle bundles or anchors coming into contact with the bristles of the already packed bristle bundles 72. This means that the tip 34 assumes the function of the previously provided, separate and separately driven tuft presser.

During the pivoting stroke between the tuft receiving position and the stuffing position or subsequently in the stuffing position, the tongue 52 has been moved relative to the base 50 by the pivoting drive in the forward direction relative to the stuffing tool 12 toward the end 36 and during said feed movement again into the guide 56 together with the used tuft.

The movement of the front end 54 of the tongue 52 in the guide 56 is linear, as is the case with a stuffing movement, by means of which the tongue 52 presses the bristle strand together with the anchor from the tip 34 out of the guide 65 into the bristle carrier 22.

The tongues 52 bend the tufts and push them into the bristle carrier 22 by means of the wire loops or the metal sheet in order then to reach the final filling position. Thereafter, a repositioning movement of the tongue 52 and the tip 34 is performed.
