Definitions

  • the invention relates to a method for producing a brush belt, in particular for use in a rotary brush tool.
  • a brush belt is equipped with transverse strips, which in turn have recesses for holding cutlery bundles.
  • the cutlery bundles are held in the strips by means of wire anchors.
  • wire anchors For this purpose, a number of blind holes is provided in each bar. This is a total of consuming.
  • a rotatably drivable brush unit which has a tensioning drum with two drum discs, a drum core and the drum discs connecting axial webs and finally a ring brush with a flexible brush belt.
  • the brush belt is equipped with outwardly projecting bristles.
  • the invention is based on the technical problem of specifying a method for producing a brush belt, with the aid of which a brush belt is provided in a simple and cost-effective manner, which is particularly suitable for gentle surface treatment.
  • an associated device should be specified.
  • the invention provides a method for producing a brush belt, in particular for use in a rotary brush tool, according to which at least one bristle is chemically and / or physically treated in the region of at least one bending point and thereby plastically deformed or deformed, and according to which the thus deformed bristle rests with its transverse web on the brush belt or a band body and engages with its treatment web, the brush belt or the band body.
  • a plurality of bristles are anchored in the band body, which have been deformed by the method described above.
  • the brush belt may then be brought into the desired shape or during the manufacturing process.
  • This can be rectangular, square, round or even polygonal. That is, the brush belt according to the invention is used to produce very different and practically arbitrarily shaped brush body.
  • one or more brush belts may be connected to each other along the longitudinal edge.
  • the brush body produced in this way is then used for any shape or surface treatment. This can be done in conjunction with a rotary brush tool or for internal cleaning of pipes as a coating for a corresponding cleaning body.
  • the respective bristle is subjected to a physical treatment, namely subjected to heat.
  • the heat input is controlled so that the respective bristle locally exceeds its softening temperature, at least in the area of the bending point, and as a result can subsequently be plastically deformed and deformed.
  • the plastic deformation process can be carried out actively on the bristle, in which, for example, a bending punch ensures that the treatment web is bent relative to the usually fixed crosspiece. It is also possible in principle, however, that the treatment bar a virtually automatic deformation relative to the transverse web due to z. B. experiences gravitational forces as soon as the bristle has exceeded its softening or melting temperature in the region of the bending point.
  • the respective bristle can basically be made of any conceivable material, that is, for example, of steel.
  • material combinations such.
  • the bristle is, as usual, a thick, stiff (artificial) hair.
  • the invention uses plastic bristles, it generally being possible to use thermoplastics such as polyamide (PA), acrylonitrile-butadiene-styrene (ABS), polycarbonate (PC), polyethylene (PE), etc.
  • PET polyethylene
  • said softening temperature is in the range of about 200 ° C or slightly above it. This temperature can be achieved according to the invention in detail without any problems by the fact that the respective bristle is heated by ultrasound and / or laser radiation until it reaches this softening temperature, specifically only and exclusively in the area of the bending point.
  • An ultrasound treatment provides for the generation of ultrasound waves, ie of elastomechanical oscillations that are located above the hearing threshold.
  • the possible ultrasound ranges from 20 kHz to beyond the MHz range and is generated regularly from electrical energy with piezoelectric or magnetostrictive transducers.
  • the sound energy thus introduced into the bristle, preferably in the region of the bending point, generates amplitudes in the micrometer range and is ultimately converted into heat, which causes the bristle to exceed its softening point at this point and to be plastically deformed.
  • the respective bristle has two bending points, so that two treatment webs are bent by a common transverse web.
  • the two treatment webs are bent in a U-shape of the crosspiece, so that they form the U-legs relative to the U-base forming crosspiece.
  • a respective angle between treatment bar and cross bar which differs from the angle of the respective bristle in the installed state. In this way it is achieved that the U-shaped bristle is introduced as it were with bias in the band body and undergoes captive a support here.
  • the brush belt or the belt body is usually equipped with through openings at predetermined positions, through which respective treatment webs are inserted so far until the associated transverse web rests against a rear side of the belt body. That is, the crosspiece acts as a stop for the respectively inserted in passages bristle. Because this is designed according to an advantageous embodiment U-shaped, two passage openings per bristle are occupied in each case, as viewed from the back of the belt body through the cross bar together are connected. In this way, the respective treatment bar protrudes by a predetermined amount relative to a front side of the band body.
  • a suitable device for producing the aforementioned brush belt is described in claim 7.
  • Advantageous embodiments are the subject matter of claims 8 and 9.
  • the invention is directed to a brush belt produced by the described method, as set forth in claims 10 and 11.
  • a method and a device as well as an associated brush belt are described, which can be advantageously used to clean and / or to work on sensitive surfaces. This applies, for example, to the inside of pipes in the food industry.
  • the brush belt is not used in conjunction with a rotary brush tool, but rather as a coating for example, a pig.
  • Other uses of the brush belt, whether as a flat or strip-like coating, are conceivable and are encompassed by the invention.
  • the production is particularly simple and inexpensive, because the bristles are brought to an advantageous embodiment in a U-shape, which can be easily anchored in the tape body easily and is held captive due to the (low) bias. Additional safety measures such as staples etc. are expressly not required.
  • the passage openings of their position and arrangement can be made virtually arbitrary.
  • the bristles inserted therein can each be adapted to this because only the length of the treatment bar on the one hand and the crossbar on the other must be changed.
  • the cleaning effect can be optimized with the brush belt according to the invention, because the distance of the protruding from the belt body treatment bars, for example, can be flexibly adapted to the respective size of the particles of dirt to be detached.
  • the invention allows the use of different strength bristles, so that a further improved adaptation to the subsequent use succeeds.
  • the band body which may be designed as a fabric band body with optionally a top-side coating.
  • the main benefits are the main benefits.
  • FIGS. 4 and 5 an apparatus for producing a brush belt 1 is shown.
  • the brush belt 1 is shown in FIGS. 4 and 5 in its basic structure of several bristles 2 together, which are anchored in a belt body 3.
  • the respective bristles 2 are U-shaped, with a transverse web 2a as the base and two treatment webs 2b as associated U-legs.
  • Both the band body 3 and the bristles 2 are made in the context of the embodiment and not limited to plastic.
  • the brush belt 1 may basically take any flat shape. It is also possible for a plurality of brush belts 1 to be connected to one another, for example, along the longitudinal edge, so that, as a result, a brush body of virtually arbitrary (planar) shape can be produced.
  • the band body 3 is constructed of a fabric of, for example, PA fibers, which are coated on its upper side 3a with a coating (see FIG. 4).
  • the bristles 2 collar against this top 3a by a predetermined amount of M before.
  • On the back 3b of the band body 3 shown in Fig. 5 can be seen individual transverse webs 2a of the bristles 2, the passage openings 4 for the treatment webs 2b connect each other.
  • the treatment webs 2b pass through the passages 4 in question. Since the bristles 2 can be made flexible, and consequently the length of the one hand transverse web 2a and the other treatment webs 2b is variable within wide limits, the distance between the through-openings 4 can be set flexibly. Furthermore, the position of the passage openings 4 can be adapted to the respective requirements, in particular with regard to the desired distance between the treatment webs 2 b on the upper side 3 a of the brush belt 3.
  • the production of the U-shaped bristles 2 takes place with the aid of the bending tool shown schematically in FIGS. 1 to 3.
  • This has at least one anvil 5 in order to fix the respectively applied bristle 2.
  • a fixing ram 6 with recessed groove 7 serves to hold the bristle 2 in a desired position with respect to the newly executed anvil 5, as indicated in FIG. 3.
  • a feed device 6 for the chemical and / or physical treatment of the bristle 2 realized at least in the area of bending points 8.
  • the feeding device 6 is integrated in the fixing ram 6 or is one and the same component.
  • bending punch 9 there is at least one bending punch 9.
  • two bending punches 9 are realized on both sides of the fixing punch 6.
  • the respective bristle is physically treated locally by heat input in the area of the bending point 8 in such a way that it exceeds its softening temperature.
  • This can be done by laser radiation of an (infrared) laser, respectively semiconductor laser or - as in the context of the embodiment - by means of ultrasound.
  • the fixation plunger 6 At the end of the fixation plunger 6 shown in detail in FIGS. 1 and 2, there is a high-frequency generator 10 which generates the required sound vibrations in a transducer 11, amplified by means of a subsequent booster 12 and via a sonotrode passing into the fixation plunger 6 directed to the bending points 8 of the bristle 2, and indeed as punctual and focused.
  • the bristle 2 is heated only in the region of the bending points 8 up to its softening temperature (about 200 ° C.), so that subsequently the now advancing bending punches 9 ensure that the bristle 2 receives its final U-shaped form.
  • the bending dies 9 may be equipped with only indicated lateral guide grooves 13.
  • an associated control system 14 moves both the fixing ram 6 and the anvil 5 and also the bending punch 9.
  • the respective bristle 2 only requires a treatment duration of approximately 10 ms (millisecond) until the softening temperature is reached and subsequently the bending dies 9 respectively advance on both sides of the fixing punch 6 in order to achieve the U-shaped configuration of the bristle 2.
  • the bristle 2 As soon as the bristle 2 has assumed its final U-shaped shape indicated by dash-dotted lines in FIG. 3, it is held in connection with the two punching dies 9 by means of the fixing punch 6 and pressed into the band body 3 subsequently guided, namely into the latter Passage openings 4. This is also shown in FIG. Previously, however, the anvil 5 is withdrawn, so that the unit from the fixing ram 6 in conjunction with the two bending dies 9 can perform this process.
  • the brush belt 3 is equipped with the passage openings 4 at predetermined positions, as Figs. 4 and 5 make clear.
  • the respective treatment webs 2b of the bristles 2 are inserted so far until the associated transverse web 2a rests against the back 3b of the belt body 3 corresponding to FIG. In this way, it is achieved that the respective treatment bar 2b protrudes by a predetermined amount M relative to the front side 3a of the band body 3.
  • the respective bristle 2 is held captive in the band body 3, close the two treatment webs 2b with the crosspiece 2a each an angle ⁇ , which is slightly larger (or smaller) designed as 90 °.
  • the bristle 2 is inserted with bias in the band body 3. Because when the bristle 2 is inserted with its two treatment webs 2b in the associated passage openings 4, ensure that both sides of the fixing ram 6 advanced bending punch 9 that the Treatment bars 2b are bent at right angles to the crosspiece 2a. If then the bristle 2 is anchored in the band body 3, the two treatment webs 2b slightly against each other and thus ensure the captive grip of the U-shaped bristles 2 in the band body. 3
