Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] This invention relates to a method and device for
manufacturing brushes.
[0003] More particularly, it relates to a method and device
whereby, on one hand, fibers are supplied to at least one filling
tool by means of at least one auxiliary device comprising at least
two fiber loading chambers and, on the other hand, said fiber
loading chambers are replenished by taking up fibers from at least
two respective fiber supply channels, whereby, by means of the
filling tool, the fibers are inserted into brush bodies.
[0004] 2. Description of the Related Art
[0005] A device of the above-described kind is already known from
the European patent application No. 0.916.283. According to the
device described therein, the auxiliary device consists of a
disk-shaped intermediary element which, along its entire periphery,
is provided with fiber loading chambers, whereby, whereas the fiber
loading chambers at one location along the periphery cooperate with
the filling tool in order to provide said filling tool with fibers,
the fiber loading chambers at another location along the periphery
cooperate with the fiber supply channels in order to be replenished
with fibers from said fiber supply channels. As a result thereof,
fibers can easily be supplied selectively out of several fiber
supply channels to a filling tool.
SUMMARY OF THE INVENTION
[0006] The invention aims at a method and device which also allow
to easily supply fibers selectively out of several fiber supply
channels to a filling tool, whereby such method and device are
optimized in many aspects and therefore offer additional
advantages.
[0007] To this aim, the invention in the first place relates to a
method for manufacturing brushes, whereby, on one hand, fibers are
supplied to at least one filling tool by means of at least one
auxiliary device comprising at least two fiber loading chambers
and, on the other hand, said fiber loading chambers are replenished
by taking up fibers from at least two respective fiber supply
channels, whereby, by means of the filling tool, the fibers are
inserted into brush bodies, with as a characteristic that, on one
hand, the supply of the fibers from the fiber loading chambers to
the filling tool and, on the other hand, the replenishing of the
fiber loading chambers with fibers from the fiber supply channels
is realized by means of working cycles which as such are
independent. By independent working cycles, thereby it is intended
that the movements performed by the fiber loading chambers take
place independently from each other, at least in certain aspects.
As a result of said independency, the advantage is obtained that
the displacement of the fiber loading chambers at the moment when
they cooperate with the filling tool, can be optimized in function
of the filling movement, whereas, apart therefrom, the displacement
of the fiber loading chambers at the moment when they cooperate
with the fiber supply channels, can be optimized in function of the
replenishing of the fiber loading chambers.
[0008] Preferably, such optimization consists in that said fiber
loading chambers during said two working cycles are moved at
different average speeds, whereby the speed during replenishing is
lower than the speed during the supply of the fibers to the filling
tool. More particularly, the fiber loading chambers, during the
supply of the fibers to the filling tool, will be moved at a high
speed, for example, of more than 500 cycles/minute, whereas this
during the replenishing of the fiber loading chambers takes place
at a speed which is considerably lower, for example, is that low
that approximately two fiber loading chambers per second are
replenished. As one works with different speeds, thus the advantage
is obtained that the replenishing of the intermediary loading
chambers in respect to the speed no longer is coupled to the speed
at which the filling tool is working, as a result of which the
intermediary loading chambers can be filled rather slow, which in
its turn results in a better filling, as well as in less
malfunctions when transferring fibers from the fiber supply
channels to the intermediary loading chambers.
[0009] In practice, it is preferred that, on one hand, the fiber
loading chambers, at the moment of their cooperation with the
filling tool, are moved to and fro according to a certain pattern,
such that successively the appropriate fibers are presented to the
filling tool and that, on the other hand, during replenishing,
these fiber loading chambers systematically and successively are
presented opposite to the fiber supply channels. In this manner, it
is obtained that the fiber loading chambers are replenished in a
smooth movement, which improves the correct working and the
exclusion of malfunctions.
[0010] In a preferred form of embodiment, one or more intermediary
magazines will be used which each comprise a series of two or more
of said fiber loading chambers, whereby each respective
intermediary magazine is rotated between a position in which it
cooperates with the filling tool, and a position in which it
cooperates with the fiber supply channels.
[0011] Furthermore, in the most preferred form of embodiment use is
made of at least two intermediary magazines which each comprise at
least a series of two or more of said fiber loading chambers,
whereby, during the cooperation of one intermediary magazine with
the filling tool, one or more other intermediary magazines are
replenished, and in this manner always an intermediary magazine is
made available for the filling tool. In this way, the continuity of
the supply of fibers to the filling tool can be guaranteed, whereas
independent working cycles, as mentioned in the aforegoing, still
can be provided for.
[0012] Moreover, the invention also relates to a device for
manufacturing brushes, in other words, a brush manufacturing
machine, more particularly a device which allows to realize brushes
according to the method described heretofore. To this aim, a device
is concerned which comprises at least one filling tool and a fiber
magazine with at least two fiber supply channels, with as a
characteristic that it also comprises an auxiliary device with at
least two fiber loading chambers, which auxiliary device
independently cooperates, on one hand, with the fiber supply
channels in order to take up fibers therefrom, and, on the other
hand, with the filling tool in order to feed the latter with
fibers.
[0013] Preferably, the auxiliary device hereby comprises at least
two intermediary magazines, each with a series of two or more fiber
loading chambers, and it is provided with drive means allowing to
displace the intermediary magazines, such that, when one
intermediary magazine cooperates with the filling tool, one or more
other intermediary magazines are replenished, and in this manner
there is always an intermediary magazine made available for the
filling tool.
[0014] In order to be able, on one hand, to guarantee a smooth
continuous working and, on the other hand, to obtain a construction
with a minimum number of components, the auxiliary device
preferably is equipped with exactly two intermediary magazines.
[0015] Preferably, the intermediary magazines are rotatable, more
particularly along one and the same axis. In a practical form of
embodiment, they consist to this end of elements in the shape of a
circle segment, whereby these intermediary magazines are rotatable
in one and the same plane.
[0016] In practice, it is preferred that the auxiliary device is
provided with drive means which allow to displace the fiber loading
chambers during the aforementioned two working cycles at different
average speeds, whereby the average speed during replenishing is
lower than the average speed during the supply of fibers to the
filling tool.
[0017] Preferably, the fiber supply channels are provided in a
shiftable fiber magazine, whereby a passage is formed in between
the auxiliary device and the fiber magazine, in such a manner that
by moving said fiber loading chambers and fiber supply channels
systematically along each other, the fiber loading chambers are
replenished with fibers.
[0018] Although the invention is useful starting with the fact that
selectively fibers have to be taken up from two fiber supply
channels and have to be supplied to a filling tool, it will take
effect in an even more optimum manner in applications in which the
selective fiber supply has to be performed from more than two fiber
supply channels. In a practical commercial embodiment, the device
will comprise five fiber supply channels, whereby the auxiliary
device is equipped with intermediary magazines with each five fiber
loading chambers.
BRIEF DESCRIPTION OF THE DRAWINGS
[0019] With the intention of better showing the characteristics of
the invention, hereafter, as an example without any limitative
character, a preferred form of embodiment is described, with
reference to the accompanying drawings, wherein:
[0020] FIG. 1 in plan view represents a device according to the
invention;
[0021] FIGS. 2 and 3, at a larger scale, represent cross-sections
according to lines II-II and III-III in FIG. 1;
[0022] FIGS. 4, 5 and 6 represent a view analogous to that of FIG.
1, however, for different positions.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0023] As represented in FIG. 1, the invention relates to a device
1 for manufacturing brushes 2, whereby fibers 3 are supplied to a
filling tool 4 which systematically, according to a well-defined
pattern, inserts fiber bundles 5, formed of fibers 3, into brush
bodies 6. Hereby, the fibers 3 are supplied from a fiber magazine 7
which, in a known manner, is provided with fiber supply channels,
in this case, a quantity of five channels 8 to 12, respectively.
The fiber magazine 7 is in a known manner provided with pressing-on
means 13 which press the fibers 3 towards the extremities 14 of the
fiber supply channels 8-12. The fiber supply channels 8-12 may be
filled with different fibers 3, whereby these fibers 3 may be of
different kinds, which means that the fibers 3 can have different
sizes and/or can be of different colours and/or of different kind.
The difference in fibers 3 is indicated by the letters A-B-C-D-E.
The fiber supply channels 8-12 can be manually or automatically
provided with fibers 3.
[0024] Between the fiber magazine 7 and the filling tool 4, an
auxiliary device 15 is present with at least two fiber loading
chambers, however, in the represented example with two series of
five fiber loading chambers, 16 to 20, respectively, which can
cooperate, on one hand, with the fiber supply channels 8-12 in
order to take up fibers 3 therefrom, and, on the other hand, with
the filling tool 4 in order to supply the latter with fibers 3. The
filling tool 4 is equipped in a known manner with a bundle take-up
element 21 with an opening 22 through which fiber bundles 5 are
separated out of the fiber loading chambers 16-20 and are presented
in front of a filling mechanism 23, whereby this latter inserts the
fibers 3 into the brush bodies 6. The bundle take-up element 21 and
the filling mechanism 23 are driven in a known, not represented
manner.
[0025] The particularity of the invention consists in that the
auxiliary device 15 is realized such that the fiber loading
chambers 16-20 can cooperate by means of independent working
cycles, on one hand, with the filling tool 4 and, on the other
hand, with the fiber supply channels 8 to 12.
[0026] In the represented example, the auxiliary device 15 to this
end is equipped with two intermediary magazines 24-25 in which each
time one of said series of fiber loading chambers 16-17-18-19-20 is
present.
[0027] The intermediary magazines 24-25 are rotatable, in this
case, along one and the same axis of rotation 26. They are formed
of elements in the shape of a circle segment, whereby these
elements are rotatable in one and the same plane around said axis
of rotation 26.
[0028] As can be seen in the cross-section of FIG. 2, the
intermediary magazines 24-25 consist of slides which can be
displaced in a common carrier 27, by means of coupling means which,
in the represented example, consist of elements 28-29 provided at
the intermediary magazines 2425, which elements can be moved in a
circle-shaped groove 30.
[0029] The intermediary magazines 24-25 each are driven by means of
a separate motor 31-32. In the represented example, these are
electric motors, for example, servo motors, however, it is clear
that also linear motors can be applied, or drive cylinders which
are coupled to the intermediary magazines 24-25 in a suitable
manner. By means of transmissions formed, in this case, of gear
wheels 33-34 cooperating with gear rims 35-36, the motors 31-32
provide for the rotation of the intermediary magazines 24-25. The
gear rims 35-36 are completely circle-shaped. Of course, according
to variants, the motors also can be arranged otherwise and other
transmissions can be applied.
[0030] As can be seen in FIG. 1, the intermediary magazines 24-25,
at their outer edges 37-38, cooperate with surrounding guides
39-40. The fiber loading chambers 1620 are situated with their open
extremities against the outer edges 37-38 and are provided with
schematically represented pressing-on means 41 which press the
fibers 3 present therein radially outward.
[0031] In the represented example, the fiber magazine 7 is made
slidable and consists of a slide 42 in which the aforementioned
fiber supply channels 8-12 are provided.
[0032] To this aim, the slide 42 is mounted in a slidable manner on
guides 43 and can be displaced by means of a worm gear 45 driven by
a motor 441 which worm gear, as represented in FIG. 3, engages in
the slide 42.
[0033] At said extremities 14 of the fiber supply channels 8-12,
the slide 42 is situated against guides 46-47 which prevent that
the fibers 3 can exit the fiber supply channels 8-12 at undesired
locations.
[0034] In between the guides 39-40, an opening 48 is formed which
allows to push the fibers 3 from the fiber loading chambers 16-20
into opening 22. At the opposite side of the auxiliary device 15,
then an opening 49 is present, such that fibers from a fiber supply
channel 8-12 presented opposite this opening 49 can be brought from
said channel into a fiber loading chamber 16-20 also presented to
the opening.
[0035] The auxiliary device 15 is provided with drive means which
allow to move the fiber loading chambers 16-20 during the
aforementioned two working cycles at different average speeds,
whereby the speed during replenishing is lower than the speed
during the supply of fibers 3 to the filling tool 4. To this end,
motors 31-32 are controlled by means of a control unit 50, whereby
said control unit 50 provides for at least three control functions,
to wit the displacement of the intermediary magazines 24-25 between
a position in which they cooperate with the filling tool 4 and a
position in which they cooperate with the fiber supply channels
8-12, the displacement of each intermediary magazine 24-25 at the
moment when this latter cooperates with a filling tool 4 in order
to provide fibers 3 to the filling tool 4 according to a certain
pattern, and the displacement of each intermediary magazine 24-25
at the moment when the latter cooperates with the fiber supply
channels 8-12 in order to replenish the fiber loading chambers
16-20 with fibers 3.
[0036] The brush bodies 6 are brought in front of the filling tool
4 by means of a workpiece holder 51. Such workpiece holders 51,
which mostly are made in the form of a drum and with which the
brush bodies 6, apart from into the filling station, also are
brought into other processing stations, are sufficiently known in
themselves and therefore they are not explained to greater
detail.
[0037] The working of the device substantially is as explained
hereafter by means of FIGS. 1, 4, 5 and 6.
[0038] In the condition of FIG. 1, the intermediary magazine 24
cooperates with the bundle take-up element 21. Hereby, said
intermediary magazine 24 is moved to and fro at a high speed,
according to a certain pattern and with a rhythm that is
synchronous to the rhythm of the bundle take-up element 21, in such
a manner that in the desired sequence fibers 3 of the kind A or B
or C or D or E are pushed into opening 22, such by placing the
corresponding fiber loading chambers 16 to 20 suitably in front of
the aforementioned opening 48. The rhythm kept during this working
cycle usually will be higher than 500 cycles/minute and mostly will
be 800 to 1000.
[0039] The intermediary magazine 25 is in a condition in which the
pertaining fiber loading chambers 16-20 have to be replenished.
Hereby, it is brought into a position in which it is situated with
one extremity close to opening 49.
[0040] In a subsequent step, as represented in FIG. 4, the fiber
magazine 7, by means of motor 44, is shifted to the left, whereas,
preferably simultaneously, the intermediary magazine 25 is turned
along opening 48, such that, step by step, the fiber supply channel
8 is brought into connection with fiber loading chamber 16, fiber
supply channel 9 with fiber loading chamber 17, fiber supply
channel 10 with fiber loading chamber 18, and so on, until a final
position is reached, as represented in FIG. 5, whereby the fiber
loading chambers 16 to 20 of intermediary magazine 25 are
completely refilled.
[0041] During the step described heretofore by means of FIGS. 4 and
5, the intermediary magazine 24 remains active, in other words,
keeps delivering fibers 3 to said bundle take-up elements 21 at the
aforementioned rhythm.
[0042] It is clear that the displacement of the intermediary
magazine 25 during filling, however, can be performed with a much
slower rhythm of movement, without the necessity of brisk
to-and-fro movements, as a result of which a steady and
trouble-free filling can be guaranteed with a large certainty.
[0043] After filling, the intermediary magazine 25 is kept ready
next to the moving intermediary magazine 24, and at a given moment,
which is determined by control unit 30, the intermediary magazine
24 is turned about into a position as represented in FIG. 6,
whereas the intermediary magazine 25 takes the place of
intermediary magazine 24 in order to be subsequently moved with
said fast rhythm and thus to provide the bundle take-up element 21
with fibers 3.
[0044] Subsequently, the intermediary magazine 24 to be replenished
is turned further up into a position as indicated by dash-dot line
52 in FIG. 6. Thereafter, the filling of the fiber loading chambers
16-20 of the intermediary magazine 24 is realized by simultaneously
displacing the intermediary magazine 24 and the fiber magazine 7.
The fiber magazine 7 then moves to the right and the intermediary
magazine 24 moves from the position represented in dash-dot line 52
in counterclockwise rotation.
[0045] Afterwards, the intermediary magazine 25 can be replaced by
intermediary magazine 24 in an analogous manner, whereby the
intermediary magazine 25 then is brought back into a position as
represented in FIG. 1.
[0046] According to a not represented variant, one or more of the
intermediary magazines can also be moved with a movement opposed to
that of the fiber magazine 7. Then, of course, sufficient distances
have to be kept in between the respective fiber loading chambers
and in between the respective fiber channels in order to prevent
that the fibers become mutually mixed in an undesired manner.
[0047] Also, controlled closing means can be provided in the
opening or passage 49 which let the fibers 3 pass only if the
desired fiber loading chamber is positioned opposite to the desired
fiber supply channel. The aforementioned movements then no longer
have to be performed simultaneously.
[0048] Likewise, the number of fiber loading chambers does not have
to be equal to the number of fiber supply channels, and two or more
fiber loading chambers can be replenished from one and the same
fiber supply channel. Vice versa, one fiber loading chamber also
can cooperate with several fiber supply channels.
[0049] It is clear that all aforementioned movements are realized
by means of the motors 31-32-44 which, to this end, are commanded
in a suitable manner by means of control unit 50 which is coupled
to the filling tool 4. For clarity's sake, control unit 50
exclusively is represented in FIG. 1.
[0050] The alteration of the positions of the intermediary
magazines 24 and 25 can simply be determined in function of the
quantity of fibers 3 taken from the fiber loading chambers 16-20,
whereby the kind of fibers which is taken up most often, is
determining for the period of time in which an intermediary
magazine has to be replenished with fibers.
[0051] The working described heretofore also illustrates the method
described in the introduction.
[0052] It is clear that different variants are possible. So, for
example, do the intermediary magazines not have to be rotating and
may also consist of slides which can be moved to and fro. The
rotating embodiment, however, allows a very compact
construction.
[0053] Also, the fiber magazine 7 can be realized in another
manner. The fiber supply channels 8-12, for example, do not have to
belong to one and the same slide 42. Also, instead of one or more
slides 42, a mechanism can be used which allows another movement
than shifting. So, for example, may the fiber supply channels 8-12
be provided in a rotatable segment, analogous to the fiber loading
chambers 16-20.
[0054] It is also possible to work with only one intermediary
magazine 24 or 25, whereby during replenishing, the filling cycle
performed by the bundle take-up element 21 is interrupted or taken
over by a second bundle take-up element, whereby this latter is fed
with fibers 3 by means of another, possibly identical supply
system.
[0055] Although the invention is represented in the drawings as for
manufacturing toothbrushes, it is clear that it can also be applied
for manufacturing other brushes.
[0056] The present invention is in no way limited to the forms of
embodiment represented as an example, however, such method and
device can be realized according to different variants, while still
remaining within the scope of the invention.
