Method of making brushes and brush making machine
The invention relates to a method for producing brushes, wherein the anchor wire is drawn off from a supply roll and fed to a cutting device, after which wire anchors are cut to length from the anchor wire and the wire anchors are then stuffed into bundle holes of the brush together with bristle bundles for fastening the bristle bundles to a brush.
The invention also relates to a
Brush manufacturing machine with a tamping tool for plugging and fastening bristle bundles in bundle holes of a brush by means of wire anchors, with a cutting device for cutting the wire anchors to length from an anchor wire fed to the cutting device, with at least one supply roll with a supply of anchor wire and with one
Main drive device for feeding the anchor wire to the cutting device and the tamping tool.
Such methods and devices are known from the prior art
Technology in different
Embodiments known.
From the publication DE 41 14
For example, 297 C2 is one

Deflection rollers and a dancer roller arranged between a supply roller and a cutting device
Bristle bundles have been around since
Decades by means of
Wire anchors fixed in bundle holes by brushes.
Especially when manufacturing smaller brushes or
Toothbrushes wish to provide the wire anchors with an anchor length that is as precise as possible and subject to only small tolerances. The aim is to ensure that the manufacturing process is as precise and reproducible as possible
BE2017 / 5542
Allow the bristle bundles to be anchored in the bundle holes of brushes.
If the wire anchor used is too long, it can be difficult to plug in the bristle bundles. If an excessively long wire anchor is used, for example, an adjacent bundle hole can be damaged. Furthermore, a tamping force that has to be applied by the tamping tool can increase if the anchor length is too long, which then may make an emergency shutdown of the brush manufacturing machine necessary.
If wire anchors with an anchor length that is too short are used to fasten the bristle bundles in the bundle holes, the required minimum pull-out force of the bristle bundles attached to the brush by means of the wire anchors can be undershot. Avoid falling below the minimum pull-out force of the bristle bundles, however, since if the pull-out force is too low, bristle bundles together with the wire anchors can detach from the brush when the brush is used as intended and, if the brush is a toothbrush, from one Users of the brush could be swallowed.
Up to now it has been known to directly pull off the anchor wire from the supply roll, which can also be referred to as a coil, and to feed it to the cutting device or the tamping tool. Such one
Brush manufacturing machine shows for example DE 29 03 399

It was also observed that supply rolls or spools cannot be unwound with a constant force. This can happen if the anchor wire is wound onto the supply reel or spool with too little precision or quality. In addition, when the anchor wire is unwound from the supply roll, short-term loops can occur, which in turn can lead to voltage peaks when the anchor wire is unwound from the supply roll or spool.
The aforementioned disadvantageous aspects do not allow the unwinding of the anchor wire from the supply roll and can cause fluctuating anchor lengths that must be avoided.
Since the

Affect BE2017 / 5542. In addition, there is a need for ever more precise anchor lengths, since the brushes or toothbrushes are made from increasingly demanding, for example harder or more brittle, materials, which also require tight manufacturing tolerances for the wire anchors.
The object of the invention is therefore to provide a method and a brush production machine of the type mentioned at the outset, with which the disadvantages mentioned above can be avoided and which allow a more precise production and provision of wire anchors for fastening bristle bundles in bundle holes of a brush.
This object is achieved in the method mentioned at the outset by the means and features of the independent claim directed to the method for producing brushes. In particular, a method of the type mentioned at the outset is proposed to achieve the object, which is characterized in that the wire buffer has two spaced-apart side walls, which laterally delimit the receiving space and between which a wire section of the anchor wire is arranged to be freely movable, and in that the anchor wire follows the withdrawal from the supply roll and before being fed to the cutting device, a receiving space of a wire buffer is fed, wherein the anchor wire is freely movable within the receiving space and with a curved or curved, depending on the degree of filling of the wire buffer up to a tensioned state of the anchor wire freely variable course is transported through the recording room.
In this way, a force and / or pulse decoupling of the main drive device responsible for feeding the anchor wire to the cutting device can be achieved from the supply roll for the anchor wire.
According to the anchor wire for feeding to the

So only the mass of the inside of the

Cutting device and the darning tool are accelerated.
The method according to the invention is thus compared to that known from the prior art

It can be advantageous if the anchor wire, in particular at the beginning of the method, for example by an installer, is arranged in the form of a loop in the receiving space and is finally moved with a loop-shaped, variable course through the receiving space of the wire buffer.
The anchor wire can be removed in a clocked manner from the wire buffer and fed to the cutting device and the stuffing tool in a clocked manner. For permanent maintenance of the decoupling of the feed of the anchor wire to the cutting device and the
BE2017 / 5542
Stuffing tool from the removal or unwinding or unwinding of the anchor wire from the supply reel or spool with the help of the wire buffer, it can be advantageous if the degree of filling of the wire buffer, i.e. in particular a length of a wire section located within the receiving space of the wire buffer, is monitored by means of a detection device
and / or is determined. Here can Anchor wire in the Wire buffers promoted becomes, if the degree of filling one defined Minimum fill level reached or falls below.In this context it can be beneficial a
Specify or set the conveying speed of the anchor wire into the wire buffer depending on the filling level of the wire buffer using a control unit. In this way, it is possible to introduce more anchor wire into the wire buffer in a shorter time if the fill level is close to the minimum fill level or reaches or falls below this.
It is possible to use an anchor wire that is round or rounded in cross-section. Such a round anchor wire regularly has a diameter that is uniform over the longitudinal extension of the anchor wire. However, an embodiment is preferred in which a flat or rectangular wire is used as the anchor wire. This flat or rectangular wire can have the standard dimensions and have an anchor width of 1.40 mm and an anchor thickness of 0.25 mm, the anchor width being understood to mean the width of the rectangular wire, preferably measured over the broad side of its cross-sectional shape, measured transverse to the longitudinal extension of the anchor wire is.
The aforementioned task is also solved with a brush manufacturing machine of the type mentioned, which the means and features of the
Brush making machine directed independent claim
BE2017 / 5542.
In particular, a brush manufacturing machine of the type mentioned at the outset is proposed to achieve the object, which is characterized in that the brush manufacturing machine has a wire take-off device arranged downstream of the at least one supply roll in the conveying direction of the anchor wire and a wire buffer arranged between the wire take-off device and the main drive device with a receiving space for receiving a Has wire section. In this recording room is the
Section of wire with a variable, curved or curved movable
Course and can be freely arranged within the receiving space and is arranged when using the device. It should be mentioned that the invention
Brush manufacturing machine in particular for
Implementation of the previously described
Procedure can be set up.
The receiving space is designed in such a way that the wire section can move freely within the limits specified by the receiving space and can assume a variable, curved or curved course. This is particularly dependent on the fill level of the wire buffer.
In this way, a brush manufacturing machine is created, which enables a force decoupling and / or pulse decoupling of the main drive device from the at least one supply roll of the brush manufacturing machine.
No guide means for guiding the anchor wire or the wire section are provided in the receiving space of the wire buffer. Only the mass of the anchor wire inside the receiving space must be in addition to that
BE2017 / 5542
Mass of drive means of the main drive device are accelerated during the cyclical removal of anchor wire from the receiving space.
In the context of the brush manufacturing machine according to the invention, a freely movable arrangement of the wire section within the receiving space of the wire buffer is understood to mean one in which the wire section is loose, i.e. unloaded, for example freely suspended, by other guiding means, such as rollers or dancer rollers or the like, within the receiving space of the wire buffer is arranged.
When the anchor wire is removed from the wire buffer or the anchor wire is fed into the wire buffer, the course of the

Receiving space of the wire buffer experiences no external voltage and is only exposed to the voltage due to
BE2017 / 5542 affects its own weight.
In this way, the overall accelerated mass when the armature wire is removed from the wire buffer in cycles is reduced to a minimum. This is not the case with brush manufacturing machines known from the prior art. Overall, the energy efficiency of the brush manufacturing machine can thus be increased and, due to the minimal mass being accelerated, the best possible shortening of cycle times when the wire anchors are cut to length from the anchor wire and when the wire anchors are plugged into the bundle holes.

According to the invention, it is also provided that the wire buffer has two side walls which are spaced apart from one another, in particular oriented in the conveying direction of the anchor wire through the wire buffer. These side walls limit the
Recording room on the side.
Between the two side walls is or is then

In this context, it can be advantageous if em

A particularly good guidance of the anchor wire in the

Anchor wire is. In particular in connection with the previously mentioned detection device for monitoring and determining the degree of filling of the wire buffer, the previously described ones
Distances between the two side walls may be advantageous.
When the armature wire is removed from the wire buffer in cycles, the armature wire can be caused to oscillate or vibrate. This can result in the armature wire moving laterally and breaking out laterally from a detection area of the detection device. If this happens, the anchor wire can no longer be reliably detected by the detection device. Basically, the distance between the side walls of the wire buffer can also increase with increasing thickness of the supplied anchor wire.

To limit the mobility of the wire section within the receiving space of the wire buffer, it can be advantageous if the wire buffer has two spaced-apart,

One, for example the aforementioned, detection device of the brush manufacturing machine for monitoring and / or determining the degree of filling of the wire buffer can be designed as an optical detection device with at least one light barrier. This detection device can preferably comprise at least two or three or four or five or even more such light barriers. The light barriers can particularly preferably be evenly spaced from one another and adjacent to the receiving space
BE2017 / 5542 the wire buffer.
In this case, light-emitting elements and / or light-receiving elements of the at least one light barrier can be recessed in a wall of the wire buffer, for example in an end wall of the wire buffer, and can be arranged at a distance from the receiving space of the wire buffer. This has the advantage that the wire section located in the receiving space of the wire buffer then does not make direct contact with the light-transmitting and light-receiving elements of the at least one light barrier of the optical detection device and contacts them in front

The brush manufacturing machine, in particular the detection device for monitoring and determining the fill level or fill level of the wire buffer, can have at least one, preferably optical fill level sensor for monitoring and / or determining the fill level of the wire buffer. This at least one fill level sensor can be directed, for example, from above or from below to an open narrow side of the receptacle space of the wire buffer to monitor the receptacle space and the degree of filling of the wire buffer. If the at least one level sensor in particular
BE2017 / 5542 is directed vertically from above onto the recording room, it is well protected against possible contamination. If the level sensor is arranged below the receiving space and is directed towards the receiving space from below, the level sensor can possibly be mounted better and more easily.
The wire take-off device can comprise a belt and at least one take-off wheel. The belt can be a toothed belt. However, it is also possible for the wire take-off device to have at least two pull-off wheels which interact with one another. The anchor wire can then be drawn off from the at least one supply roll and fed to the wire buffer both with a belt and with a pull-off wheel assigned to the belt and with two interacting pull-off wheels.
For tensioning the belt, the wire pull-off device can also comprise a tensioning wheel which is assigned to the belt and whose distance from at least one other belt wheel, via which the belt can be guided, can be changed. The tensioning wheel can also be driven by means of a corresponding tensioning drive.
It is possible that the belt has a trigger drive with which the belt and / or the at least one trigger wheel, which is assigned to the belt, can be driven. However, it is also possible to drive at least one of the at least two trigger wheels with such a trigger drive.
In order to be able to prevent the drawn-off anchor wire from running back in the direction of the supply roll, it can be advantageous if the at least one take-off wheel or at least one of the at least two take-off wheels is / are connected to a freewheel which is effective in the conveying direction of the anchor wire. This means that those equipped with a freewheel
BE2017 / 5542
Puller wheels are freely rotatable in the conveying direction of the anchor wire, but rotation of the puller wheels equipped with the freewheel in the opposite direction is prevented. Instead of a freewheel, a motor with a brake and / or a self-locking geared motor can also be used on the trigger wheels concerned in order to prevent the return described above.
The wire take-off device can have at least one
Have pressing device.
With this pressing device, one of the two above-mentioned extraction wheels can be pressed onto the other in order to promote the
Favorable friction to the anchor wire
Build up anchor wire.
But it is also possible with the
Pressing the belt against that assigned to it
Press the trigger wheel or the trigger wheel against the belt.
In one embodiment of the brush production machine according to the invention, it can also be provided that the wire removal device has at least one clamping wedge drive for removing the anchor wire from the at least one supply roll.
In particular in connection with the use of such a clamping wedge drive for pulling off the anchor wire from the at least one supply roll, it can be advantageous if the
Brush making machine one
Deflection device with one
Deflection wheel and / or with one
Guide sleeve for the
Has anchor wire.
The
Deflection device can be between the at least one
Supply roll and the wire take-off device can be arranged.
This enables the armature wire to be fed precisely to the drive elements of the wire take-off device arranged downstream of the deflection device. For precise guidance of the anchor wire, the deflection wheel can be one, in particular
BE2017 / 5542 have conical, guide groove, in the the Anchor wire in Position of use arranged is. The Deflection wheel can also a Counter wheel be assigned, with the the Anchor wire in the
Guide groove of the deflection wheel can be held. This measure can also be used to precisely guide the anchor wire through the deflection device.
For feeding the anchor wire to the cutting device and the downstream one
Darning tool can

However, it is also possible for the drive belt and a drive wheel and / or at least one clamping wedge drive to be included for this purpose. The drive belt that the
Drive belt assigned drive wheel or the two drive wheels can each be driven. However, it is also conceivable to drive only individual drive wheels or only the drive belt. For this purpose, the main drive device can be equipped with corresponding drives or motors.
To the for the feeding of the anchor wire with the help of
Main drive device required contact pressure on the

Main drive device have at least one pressing device. With this pressing device, at least one of the two drive wheels can be pressed against the other drive wheel and / or the drive belt against the drive wheel assigned to it. However, it is also conceivable to use a pressing device of this type
Drive wheel against the
Press drive belt.
When using a belt in the
Interaction with one
Trigger wheel it can be advantageous if the belt wraps around the trigger wheel assigned to it at an angle of approximately 90 °.
A particularly reliable development of the anchor wire from
BE2017 / 5542 of the at least one supply roll can be achieved if the wrap angle of the belt around that assigned to it
Trigger wheel is larger, for example 180 °, 210 °.
The

This can in particular in the conveying direction of the anchor wire

Clamping wedge drive
Main drive device, upstream in the conveying direction of the anchor wire. The main deflection device between the wire buffer and the
Main drive device may be arranged. To the
To be able to reliably deflect the armature wire, the deflection wheel can have a, in particular conical,
Have a guide groove for guiding the anchor wire. In addition, a corresponding counter wheel can be assigned to the deflection wheel. This can engage in the guide groove of the deflection wheel. The armature wire can then be fed between the deflection wheel and the counter wheel in the guide groove of the main drive device.
The main deflection device can increase the accuracy with which the anchor wire of the
Main drive device can be supplied.
In order to reduce or even avoid the occurrence of slippage between the supplied anchor wire and the corresponding feed means of the pull-off device and / or the main drive device or also the respective deflection device and / or the main deflection device, it can be advantageous if an outside of the belt contacting the anchor wire and / or at least one pull-off wheel and / or one, for example the drive belt mentioned above and / or at least one drive wheel and / or one, for example the one already mentioned
BE2017 / 5542 mentioned deflection wheel and / or one, for example the aforementioned deflection wheel of the main deflection device assigned to the main drive device with an anti-slip
Coating is provided.
This anti-slip coating can consist of plastic, rubber or synthetic rubber, for example. Both the main drive device and the
Wire take-off devices can each have a sensor for detecting an anchor wire in the main drive device and / or in the wire take-off device. In this way it can be ensured that an empty run of the brush manufacturing machine can be detected at an early stage.
Furthermore, it is possible for the at least one supply roll to be assigned a supply sensor for monitoring and / or determining a wire supply on the supply roll. The supply sensor can be, for example, a sensor roll that contacts the anchor wire wound on the at least one supply roll. Depending on the position of the sensor roll on the supply roll, the remaining stock of anchor wire on the supply roll can then be inferred. However, it is also possible to design the stock sensor as an optical sensor.
However, it is also possible for the brush production machine to have a dancer roll, which is arranged downstream of the at least one supply roll in the conveying direction. This dancer roll can then be used to indicate that the supply of anchor wire on the at least one supply roll has been used up. As soon as there is no longer any anchor wire on the supply roll, the dancer roll lying in the use position on an anchor wire section running between the at least one supply roll and the take-off device changes its position. As soon as this happens, it becomes apparent
BE2017 / 5542 that the supply of anchor wire on the at least one
Supply roll is used up.
In order to be able to prevent the supply roll from turning back against the conveying direction of the anchor wire, it can be advantageous if the at least one supply roll has a freewheel which is effective in the conveying direction of the anchor wire.
Finally, it should be mentioned that the wire buffer mentioned several times before can be designed as a so-called wire holder. The wire holder can have the previously mentioned two oppositely arranged side walls and the two oppositely arranged end walls which connect the two side walls to one another. The receiving space of the wire buffer then results between the side walls and the end walls. Thus, the wire holder as a receptacle for receiving the in the
Wire buffer arranged wire section can be viewed. The wire section is freely movable within the wire holder. A mobility of the wire section within the
Wire quiver is only from the side walls and the two
End walls connecting side walls limited. Depending on the fill level of the wire buffer, the
Wire section none of the
Side walls or
Contact the end walls or just one or some or even all of the walls of the
Touch wire buffer.
This is possible because the wire section is freely movable within the receiving space. There are therefore no further guiding means within the receiving space of the wire storage device which would influence the course of the wire section which is freely variable within the receiving space. Thus, the wire section within the wire buffer is loosely arranged and between the two already mentioned, on the one hand by the
Main drive device and on the other hand by the
BE2017 / 5542
Pre-deduction device hung predetermined fixed points.
Overall, a high clock frequency when removing the
Anchor wire from the wire buffer for feeding the
Anchor wire to the cutter and tamping tool
reached be, since only the mass of the within the
Wire buffer arranged wire section must be accelerated.
Below are exemplary embodiments of the invention based on the

The brush making machine has one
Darning tool 2, a cutting device 3, at least one supply roll 4 with a supply of anchor wire 5 and one
Main drive device for feeding the anchor wire to the cutting device 3 and the tamping tool 2.
As shown in particular in Fig. 1, this anchor wire is here as

In order to be able to determine the fill level of the wire supply in the supply roll 4, an ultrasonic sensor can be provided which is aligned directly with the supply roll 4.
With the aid of the cutting device 3, the wire anchors 10 can be cut to length from the anchor wire 5 fed to the cutting device 3 in a length required for fastening the bristle bundles 7 in the bundle holes 8.
With
With the help of the main drive device 6, the armature wire 5 is the
Cutting device 3 and the stuffing tool.
In order to decouple force and momentum between the
To enable the main drive device 6 and the supply roll 4, the brush manufacturing machine 1 has one of the
Supply roll arranged downstream in the conveying direction of the anchor wire, and a wire withdrawal device 12 between the
Wire take-off device and the
Main drive device 6 arranged wire buffer 13.
The wire buffer 13 includes a receiving space 14, which serves to receive a wire section 15 of the supplied anchor wire 5. In the receiving space 14, the wire section 15 is arranged to move freely up to a tensioned state with a variable, curved or curved course within the receiving space 14. This can be seen particularly well from FIGS. 1, 2 and 3.
There is no guide element acting on the wire section 15, such as, for example, a guide roller or a dancer roll, within the receiving space 14, which guards the free mobility of the wire section 15
BE2017 / 5542 would restrict or impair within the receiving space 14. The wire section 15 of the armature wire is therefore essentially free of tension within the receiving space 14.
This is the course of the wire section 15 within the
Recording space 14 by removing anchor wire 5 from the
Wire buffer 13 or by feeding anchor wire 5 in the
Wire buffer 13, that is, depending on a degree of filling of the
Wire buffer 13 changeable without resistance. Forces which act on the mass of the wire section 15 or frictional forces which act between the wire section 15 and an inner wall 19, 20 of the wire buffer 13 when the
Wire section s 15, as can be seen in FIG. 3, may not be regarded in the context of the invention as relevant resistances or forces affecting the mobility of the wire section within the receiving space 14.
The wire section 15 within the receiving space 14 of the wire buffer 13 can thus be shortened without resistance and force-free by removing anchor wire 5 from the receiving space 14.
According to FIGS. 1, 2 and 3, the wire section 15 is arranged in the receiving space 14 in the form of a wire loop 16.
Through the loop-shaped
Course of the wire section within the
Recording space 14 gives way to a length of
Wire section of a minimal
Length that he would take if he was along a direct connection between the

These

Clock frequency can be removed from the receiving space 14 of the wire buffer 13.
Only the wire section 15 arranged in the wire buffer 13 has to be accelerated for the cyclical feeding of the anchor wire 5 to the cutting device 3 and the stuffing tool 2. Further guide elements which increase the mass to be accelerated, such as guide rollers or dancer rollers and / or dancer rollers, which could guide the wire section 15 within the receiving space 14 of the wire buffer 13 with a certain tension and impair the free mobility of the wire section 15 within the

Monitoring and determination of a fill level of the wire buffer set up.
The wire buffer 13 comprises two spaced apart side walls 19 which are oriented in the conveying direction of the anchor wire 5 through the receiving space 14 of the wire buffer 13 and which laterally delimit the receiving space 14. The wire section 15 is arranged to move freely between the two side walls 19, so it can only assume any position within the receiving space 14 to a limited extent due to the side walls 19 and possibly limited by its internal stress. It should be mentioned once again that within the receiving space 14 there is no wire section 15
BE2017 / 5542 for guiding means bringing into any forced position
Guide of the wire section 15 within the receiving space 14 of the wire buffer 13 are present.
A distance between the two side walls 19 is greater than a diameter or the anchor width of the anchor wire 5. Depending on the diameter or anchor width of the anchor wire, the distance between the side walls 19 can be between 0.05 mm and 3.0 mm larger than a diameter or the anchor width of the supplied anchor wire 5.
In one embodiment of the brush manufacturing machine 1 according to the invention, which is not shown in the figures, it is provided that the distance between the side walls 19 from one another can be set as a function of a diameter or as a function of the armature width of the supplied armature wire 5. This in order to be able to adapt the brush manufacturing machine 1 to different anchor wires for manufacturing different brushes.
In addition to the two spaced apart
Sidewalls 19, the wire buffer has two mutually spaced transverse or perpendicular to
Direction of funding of
Anchor wire through the
Recording space 14 of the wire buffer oriented
End walls 20 on. These end walls connect the

Thus the
Receiving space 14 on the one hand through the two mutually spaced side walls 19 and on the other hand through the two spaced apart
End walls 20 defined.
Between the two end walls is the

Apply wire buffer 13.
In the
Variant of the invention
Brush manufacturing machine 1 according to Figure 3 with a
Comparison to the embodiment of the wire buffer according to Figures 1 and 2 narrower wire buffer 13, which also as
Wire quiver can be called, there is
Advantage in the front

20. Due to the friction between the
End walls and the wire section 15 can vibrations and other uncontrolled occurring when the anchor wire 5 is removed from the wire accumulator in cycles
Movements of the wire section 15 within the receiving space of the wire buffer 13 can be reduced or even avoided.
The exemplary embodiments of the wire buffer 13 shown in the figures have in common that the distance between the two end walls 20 is a multiple of the distance between the two side walls 19.
According to FIG. 3, the distance between the two end walls 20 is selected and matched to the anchor wire 5 processed by means of the brush manufacturing machine 1 in such a way that the wire section 15 contacts the two end walls 20 within the receiving space 14.
For monitoring and determining the degree of filling of the wire buffer 13, the detection device 17 is designed as an optical detection device 17. The detection device 17 can have ultrasonic sensors or other, preferably non-contact sensors as sensors 18. In this one
BE2017 / 5542 shown embodiment has the
Detection device 17 sensors 18, which are designed as light barriers 21 which are preferably evenly spaced from one another. Each of the light barriers 21 in each case comprises a light emitting element 22 and a light receiving element 23, which are arranged in pairs opposite one another on the end walls 20 of the wire buffer 13.
In particular, the sectional representations of the wire buffer 13 according to FIGS. 2 and 3 make it clear that both the light-transmitting elements 22 and the light-receiving elements 23 of the light barriers 21 are recessed in the end walls 20 of the wire buffer 13 and are arranged at a distance from the receiving space 14 of the wire buffer 13 . In this way, the light-emitting elements 22 and also the light-receiving elements 23 are well protected against contamination or damage by the wire section 15 of the armature wire 5, which is freely movable within the receiving space 14.
The light barriers 21 of the detection device 17 are aligned parallel to the side walls 19 of the wire buffer 13. This means that light beams 24 forming between the light transmitting elements 22 and light receiving elements 23 propagate parallel to the side walls 19 of the wire buffer 13 within the receiving space 14. The functioning of the light barriers 21 can be seen particularly well from FIG. 2.
Here, the wire loop 16 of the wire section 15 extends so far from above into the receiving space 14 of the wire buffer 13 that four of the five light barriers 21 arranged vertically one above the other and at a distance from one another are connected. Only in the lowermost light barrier 21 is that between the light emitting element 22 and the
BE2017 / 5542
Light receiving element 23 trained light beam 24 Not interrupted. On these Way the Spread the Wire loop 16 of Wire section 15 within of Recording room 14 of Wire buffer 13 with help the non-contact Detection device 17 can be determined.
At the latest when the wire loop 16 of the wire section 15 has been pulled out of the wire buffer 13 by the removal of anchor wire 5 from the receiving space 14 to such an extent that it no longer switches the uppermost one of the light barriers 21, the wire pulling device 12 can issue a corresponding request in the form of a control signal receive anchor wire 5 to replenish the wire buffer 13 in the receiving space 14.
As soon as the wire buffer 13 has reached a desired degree of filling, for example when all five light barriers 21 are switched again due to the wire loop 16 of the wire section 15 reaching into the receiving space 14, the wire withdrawal device 12 can receive a corresponding control signal, as a result of which the anchor wire 5 is further conveyed is stopped in the wire buffer 13.
In one embodiment of the brush manufacturing machine 1 according to the invention, not shown in the figures, it is provided that the brush manufacturing machine
1, for example the detection device 17, at least one, preferably optical,

Degree of filling of the

This fill level sensor can then be used to supplement or replace the light barriers 21. It can be provided that the level sensor on the
BE2017 / 5542
Brush manufacturing machine 1 is arranged that it is directed to an open narrow side 25 and from above or from below through the open narrow side 25
Recording space 14 of the wire buffer 13 optically monitored.
According to FIGS. 1, 2 and 3, the wire take-off device has a belt 26, which can be designed, for example, as a toothed belt. In addition to the belt 26, the wire take-off device 12 has a take-off wheel 27. The trigger wheel 27 is wrapped by the belt 26 with a wrap angle of approximately 90 °. Larger wrap angles are possible and, depending on the application, also desirable.
The anchor wire 5 is arranged between the belt 26 and the take-off wheel 27. With the help of the belt 26 and the pull-off wheel 27, the anchor wire 5 can be pulled off the supply roll 4 and fed to the wire buffer 13. According to FIG. 1, the belt 26 runs over two belt wheels 28, which bring the belt 26 into the arrangement required for wrapping the take-off wheel 27.
A tensioning wheel 29 is arranged between the two belt wheels 28. A tensioning drive 30 is assigned to the tensioning wheel 29, by means of which the relative position of the tensioning wheel 29 to the two other belt wheels 28 can be changed in order to generate a tension of the belt 26.

Upstream of the wire withdrawal device 12 in the conveying direction of the anchor wire 5, the brush production machine 1 has a deflection device 35. This deflection device 35 comprises a deflection wheel 36, a guide sleeve 37 for the anchor wire 5 and a counter wheel 38 assigned to the deflection wheel 36, by means of which the anchor wire can be reliably pressed onto the deflection wheel 36 in order to deflect the anchor wire 5.
In order to be able to prevent the armature wire 5 from slipping sideways from the deflection wheel 36, the deflection wheel 36 has a conical guide groove 39 on its outer circumference for guiding the armature wire 5. A top view of the deflection wheel 36 and the counter wheel 38 assigned to the deflection wheel 36 is shown in FIG. The guide groove 39 of the is also good here

The deflection device 35 is arranged between the supply roll 4 and the wire draw-off device 12.
According to FIGS. 1 and 2, the main drive device 6 of the brush manufacturing machine 1 shown there has two mutually associated drive wheels 40 and 41.
In the variant of the brush-making machine 1 shown in FIG. 3, the main drive device 6 comprises two clamping wedge drives 42, 43 arranged one behind the other, with which, as with the two drive wheels 40, 41, the anchor wire 5 of the cutting device 3 and the tamping tool 2 can be fed in cycles. According to FIG. 1, each of the two drive wheels 40, 41 is assigned a drive motor 44, which apply the torque required for feeding the armature wire 5.
When using clamping wedge drives 42, 43 according to the figure, either the front clamping wedge drive 42 can be moved or both can be moved in opposite directions, each of the two clamping wedge drives 42, 43 then only executing half a stroke.

Supply roll 4 can be rotated against the conveying direction. This would lead to an undesired tension or movement of the armature wire 5 against the actual conveying direction, which in turn could impair the accuracy and the operation of the brush manufacturing machine 1.
The brush manufacturing machine 1 has a main drive shaft on which three double eccentrics are formed. A first double eccentric is responsible for a lifting movement of the tamping tool 2 and a pusher tongue 46 movably arranged therein. A lifting movement of the cutting device 3 can be generated with a second double eccentric. A third double eccentric is connected to the clamping wedge drives 42, 43 via an adjustable lever system in order to drive them or only one of these two.
According to the sectional view of the cutting device 2 according to
Figure 2 has the cutting device 2 in its interior
Stop surface 57 for the cutting device 2 fed
Anchor wire 5 on.
The method described below can be carried out on the brush production machine 1 described above.
In order to produce brushes 9, anchor wire 5 is pulled off the supply roll 4 and fed to the cutting device 3. In the cutting device 3, wire anchors 10 are cut to length from the anchor wire 5 and then together with bristle bundles 7 for fastening the bristle bundles 7 to the brush 9 by means of the tamping tool 2 in bundle holes 8
BE2017 / 5542
Brush 9 stuffed. For this purpose, the bristle bundles 7 are transferred to the tamping tool 2 in a manner known per se. For this purpose, the stuffing tool 2 has a receiving notch 47 within which the bristle bundles 7 to be stuffed can be arranged.
With the aid of the ram tongue 46, the wire anchor 10 held ready can be stuffed together with the bundle of bristles 7 arranged in the receiving notch 47 into the corresponding bundle hole 8 of the brush 9 provided on the brush holder 11, which is still shown here as a very schematically represented brush body 9a or bundle holding plate.
It is provided that the anchor wire 5 is fed to the receiving space 14 of the wire buffer 13 after it has been pulled off the supply roll 4 and before being fed to the cutting device 3. The armature wire 5 is freely movable within the receiving space 14, that is to say it is not held under a certain tension or forced into a certain position by any guiding element within the receiving space. The anchor wire 5 assumes a curved or curved course within the receiving space 14, which varies freely depending on the filling level of the wire buffer 3 up to a tensioned state of the anchor wire 5 and can be transported with this course through the receiving space 14.
The
Course of the anchor wire 5 within the
Recording room 4 by removing anchor wire 5 from the
Wire buffer 13 unloaded, changed resistance-free and force-free, in particular shortened. The armature wire 5 is transported through the receiving space 14 in a force-free, resistance-free manner and under a lower tension than transport sections upstream or downstream in the wire buffer 13. This way he can move within the limits of the
BE2017 / 5542
Arrange or align the receiving space 14 of the wire buffer 13 freely.
When the brush manufacturing machine 1 is set up, the anchor wire 5 is formed into the loop 16, arranged in the receiving space 14 and then moved through the receiving space 14 of the wire buffer 13 with a loop-shaped, resistance-free and force-free variable course.
The anchor wire 5 is removed from the wire buffer 13 in a clocked manner and fed to the cutting device 3 and then to the stuffing tool 2 in a clocked manner. The fill level of the wire buffer 13 is monitored and determined by means of the detection device 17. Anchor wire 5 is then fed into the wire buffer 13 when the fill level reaches or falls below a defined minimum fill level. In this case, a conveying speed of the armature wire 5 into the wire buffer 13 can be predetermined and set as a function of the detected degree of filling of the wire buffer 13 by means of a central control unit 48.
FIG. 5 shows a simplified illustration of a circuit for operating the brush manufacturing machine 1 according to the invention. The brush manufacturing machine 1 and the central control unit 48, which can be arranged in a control cabinet 54, can be seen in the lower part of this illustration. The central control unit 48 controls the main drive device 6 and thus switches on the drive motors 44 or the clamping wedge drives 42, 43. In general, the sensors 18 or specifically the light receiving elements 23 of the light barriers 21 of the detection device 17, which can also be referred to as light guide sensors, report the filling level of the wire memory 13, which can also be referred to as a wire holder, via I / O units 56 and a CAN bus system 55 to the central control unit
BE2017 / 5542
48. In addition to CAN bus systems, other bus systems can also be used. In principle, the use of direct control without a bus system is also conceivable.
Depending on the fill level of the wire store 13, the trigger drives 31 are activated for refilling the wire store 13.
In the simplest embodiment of the brush manufacturing machine 1, a relay 49 connects a power supply 51 to the drive motors 44 and trigger drives 31, which are designed, for example, as DC motors. A resistor 50 can control the speed of the drive motors 44 and also the speed
Specify trigger drives 31. Resistor 50 can be an adjustable resistor, since the speed of drive motors 44 and trigger drives 31 can be variably adjusted in this way.
According to FIG. 5, the brush manufacturing machine 1 has two relays 49 and two variably adjustable resistors 50, which are connected to the power supply 51. The power supply 51, the relay 49 and the resistors 50 are connected to the trigger drives 31 and the tensioning drives 30 via a supply line 52.
In one embodiment of the brush manufacturing machine 1, which is not shown in the figures, several relays and resistors can be connected in parallel, so that depending on the filling level of the wire storage device 13 different conveying speeds of the drive motors 44, the clamping wedge drives 43, 44 and / or also the trigger drives 31 and the tensioning drive 30 can be set.
BE2017 / 5542
In order to be able to implement a particularly precise control, tension drives 30, trigger drives 31 and also as
Drive motors 44 of the main drive device 6 servomotors or stepper motors can be used.
The drive motors 44 of the main drive device 6 are controlled via controller 53, which is subordinate to the central control unit 48.
The central control unit 48 is housed by the control cabinet 54, which is shown only in a highly schematic manner.
