Definitions

  • the invention relates to a cleaning roller of a scraper roughening machine with line and / or counter-streak roughening rollers for cleaning the roughening fittings of these roughening rollers, which are rotatably mounted on the circumference of a drum turned during operation.
  • a scraper rougher essentially consists of a cylindrical roughening drum, which is axially rotatably mounted.
  • the line and / or counterstroke rollers which are thin relative to the reel diameter, are stored next to one another, if necessary alternately.
  • the basic difference between these two types of roughing rollers is that the scratches consisting of a scratching neck and scratching hook or lower tooth and upper tooth are inclined differently in the direction of rotation or have differently bent scratching hooks or upper teeth.
  • the scratch coating of the roughing rollers (dash or counter-coating rollers) is also referred to overall as a roughing set or scratching fitting.
  • the roughing drum can also be filled with roughing rolls of one type or another. It is then possible, for example, to alternately connect correspondingly equipped dash and counter stroke drums in succession on a fabric web treatment line.
  • the cleaning rollers are usually attached below the rough drum; they are intended to ensure that the scratching on the coating and counter-coating rollers does not get covered with rough flakes and fiber residues during work.
  • the cleaning rollers generally have two diametrically opposed brush segments or brush blades that extend over the entire length of the roller; these are elongated flat brushes that consist of a large number of individual bristles. If the respective roughing drum is equipped with roughing rollers of only one or the other type, all-round (fully) bristled cleaning rollers can also be provided.
  • the cleaning rollers should brush the scraper fittings in such a way that the bristles of the brush blades attack both the individual scraper scraper and the scraper scraper from behind, that is to say on their "concave” side, and "overtake” because of the speed difference.
  • each roller series (line or counter-line) is assigned a separately (inevitably) driven cleaning roller.
  • the cleaning rollers are generally rotated much faster than the respectively cleaned dash and counter-coating rollers. -
  • a single cleaning roller, which can be bristled all around, is often sufficient for a roughing drum with only one single roughing roller type.
  • Both these known bristles inclined to the rear and the generally common bristles standing radially with respect to the axis of the cleaning roller cause shocks and vibrations in that the individual bristles hit the upper teeth of the rough scratches at an angle and do not always provide satisfactory performance because the radial ones When hitting the respective roughening set, bristles first press the fluff or fiber remnants therein into the interior of the roughening set and only then try to convey them out of the set.
  • the object of the invention is to improve the efficiency, that is to say the cleaning action, of the cleaning rollers and to reduce the excitation of roughing roller vibrations or blows caused by the cleaning rollers.
  • This is achieved according to the invention in a cleaning roller of the type mentioned above in that the bristles of the cleaning roller are inclined forward in the direction of rotation of the cleaning roller such that the bristles are bent approximately perpendicularly to those currently in the contact area at the start of contact between the cleaning roller and the respective roughing roller
  • the upper teeth of the set of teeth are standing.
  • even worse than the radial bristles are the bristles inclined obliquely backwards in the direction of rotation according to DE-GM 74 21 809 mentioned above.
  • the known radial bristles - and especially the bristles inclined obliquely backwards - are namely in the Roughing set "knocked in” so that they first press the lint and fiber residues to be removed obliquely inwards with respect to the raising roller and only then pull it out of the latter. A remnant often remains on the roller core. Over time, these "remaining" fluff and fibers can collect, so that a basic cleaning with dismantling of the roughing rollers becomes essential.
  • the alignment of the bristles of the cleaning rollers according to the invention leads, as I said, to the fact that the bristles do not somehow strike obliquely against the scratches of the respective scraping set, but rather, like needles, penetrate approximately vertically into the interior of the roughing set.
  • This has another advantage, namely that the dreaded blows and vibrations of the roughing rollers are reduced to a level that is no longer disturbing.
  • the brushing machine shown in FIG. 1, shown in principle, has an essentially cylindrical hooking drum, generally designated 1, which inevitably rotates about the drum axis 3 in the direction of rotation 2.
  • the circumference or shell of the drawn rough drum 1 essentially consists of a sequence of coater rollers 4 and counter-coater rollers 5 mounted coaxially to the reel axis 3.
  • the latter should likewise have a positive drive, the rotational speeds in the directions of rotation 6 of the coater roller 4 and 7 of the counter-coater roller 5 can differ and the drum direction 2 should be opposite.
  • a fabric web 10 is pulled over the periphery of the roughing drum 1, which is currently peripheral to the drum on the peripheral parts of the scraper fittings 8, 9 of line and counter-stroke rollers 4 and 5.
  • the latter should run onto the drum 1 via a feed roller 11 and be conveyed further in the transport direction 13 via a feed roller 12.
  • each of the cleaning rollers has two over the entire cylinder length of the rough drum, e.g. over 2 m, extending brush blades 18 and 19, respectively.
  • the rotary movement of the spool 1 and the rotary movements of the cleaning rollers 14 and 15 are coordinated in such a way that the line-cleaning rollers 14 only brush the 4 rollers and the counter-cleaning rollers 15 only brush the counter-rollers 5.
  • the tuning should be carried out in such a way that either only one coating roller 4 or one counter-coating roller 5 is cleaned at the same time.
  • the cleaning can be done in the following way: A brushing blade 19 of the cleaning roller 15 brushes a counter-coating roller 5 passing in the drum circulation. When this first cleaning roller is rotated by 90, a gap between the two brushing blades 19 of the roller 15 is cleared. A line roller 4, which is moved past in the direction of rotation 2 of the drum, passes through this gap, the scratching coating 8 of which can therefore not be hit by the cleaning roller 15. If this line roller 4 now comes into the area of the line cleaning roller 14, the bristles of a brush blade 18 are here ready for cleaning.
  • the cleaning rollers must inevitably be driven according to the exemplary embodiment, preferably with the aid of gearwheels, which have to ensure the correct runout and the necessary cooperation between the cleaning rollers and the roughing rollers intended for them without the slightest shift.
  • each cleaning roller 14, 15 Assuming that one rotates a roughing drum 1, which is equipped with 24 roughing rolls (12 dash and 12 counterstroke rolls) by 1/24 of its concentricity, i.e. by 15 °, it rotates accordingly Above each cleaning roller by a 1/4 turn, that is, by 90 °. A full turn of the cleaning roller will therefore clean two of one type of nip roller, and if there are twelve nip rollers of each type, six turns of a cleaning roller will account for one turn of the reel.
  • FIGS. 2 and 3 two cleaning rollers 14, 15, each having two diametrically opposed brushing blades 18, 19, are assigned to a detail of a drum with dash and counter-coating rollers 4, 5 in an enlarged representation.
  • the brush blades 18 and 19 of the two cleaning rollers 14, 15 are at best essentially radial with respect to the axes 16 and 17 of the two cleaning rollers 14, 15.
  • FIG Brush blades 18, 19 of the two cleaning rollers 14, 15 so inclined (inclined) to the front that the bristles 26 (according to FIG. 4) in the respective direction of rotation 20 or 21 of the rollers 14 and 15 form an angle with respect to the upper tooth 25 of the scrapers 22 of about 90 °.
  • Each scraper 22 should consist of a scraper wire, with a scraper neck or lower tooth 24 fastened in a scraper cover 23 and with a scraper hook bent in relation to the latter or upper tooth 25 exist.
  • the scraper fittings 8, 9 of the coating and counter-coating rollers 4, 5 are in principle similar, but the upper teeth 25 of the coating and counter-coating rollers 4, 5 are bent in the opposite direction with respect to their respective directions of rotation 6, 7.
  • a cleaning roller 14 with individual bristles 26 (FIG. 4) of the respective brush blade 18 aligned radially with respect to its axis 16 exerts a cleaning effect on a line roller 4, because the line roller 4 precisely in the direction of rotation 2 of the drum 1 on the Cleaning roller 14 runs past, brush or hit the bristle tips 27 of the individual bristles 26 obliquely on the back of the upper teeth 25 and, depending on the setting, penetrate more or less deeply into the scraper fitting. This oblique stop of the upper teeth 25 causes shocks or vibrations on the roughing rollers 4, 5.
  • the bristle tips 27 first press the lint or thread remnants collected in the scraper fitting 8 of the line roller 4 onto the inside of the scraper fitting and only then out of it. A small part of the dirt often remains in the area of the attachment points of the lower teeth 24.
  • the brush blades 18 and 19 of the streak and counter-stroke cleaning rollers 14 and 15 are inclined forward according to the invention obliquely in the direction of rotation 20 and 21 of the cleaning rollers 14 and 15, the bristle tips 27 prick in a direction approximately perpendicular to the back the upper teeth 25 into the interior of the rough fitting 8, 9.
  • the back of the upper teeth of the scrapers 22 lies on the concave scraping side, which lies in the front in the direction of scraping in the direction of scraping and in the direction of the scraping in the direction of the scraping in the back.
  • the bristles 26 of the brush blades 18 convey any dirt from the roughening set by the circumferential rotation of the latter at least as well as in FIG. 2. This is essentially achieved in that the bristles 26 of the cleaning rollers 14 and 15 which penetrate the roughing set have a high peripheral speed in relation to the drum.
  • FIGS. 2 and 3 do not expressly show the mutual assignment of the scraper assembly and bristles of the cleaning roller at the moment of the respective brushing action. however, it can be imagined how a brush blade 19 meets a counter-stroke roller 5 if the rough drum according to FIG. 2 or 3 continues to rotate in the direction of rotation 2 and at the same time the counter-stroke cleaning roller 15 rotates in the direction of rotation 21 with a considerably greater angular velocity.
