Definitions

  • the present invention relates to a brush ring or a disc brush with a ring-shaped frame part, which is axially slidable on a shaft and secured against rotation to form a sweeping roller.
  • Brush rings or disc brushes are as such in the art, such as from the DE 39 14 745 A1 known. They have a substantially circular trained frame part, on which radially outwardly projecting bristles are arranged. To form a sweeping roller several such disc brushes are pushed onto a rotatably mounted shaft and rotatably connected to the shaft to be rotated.
  • the radially inner, the bristle receiving brush ring for example, have a largely planar, but also a zigzag-shaped structure.
  • Such zigzag or wavy structures contribute to a uniform bristle density on the outer circumference of the sweeping roller. Also can be counteracted by a zigzag or wave profile of a groove formation on the substrate to be cleaned.
  • the brush ring according to the invention has a ring-shaped frame part, on which radially outwardly projecting bristles can be fastened.
  • the brush ring or bristle-equipped brush disk is axially pushed onto a shaft to form a sweeping roller.
  • a driver device is provided, by means of which the frame member rotatably connected to the shaft.
  • the frame part has a radially inwardly projecting entrainment device, for example in the form of one or more radially inwardly directed pins, which are insertable into a corresponding recess or groove of the shaft.
  • the frame part is preferably made of a thermoplastic material and thus can be positively and / or materially connected to the bristles.
  • the bristles to be fastened to the frame part can equally be made of a thermoplastic plastic, for example of polypropylene, but also of metal, in particular corrugated metal wire.
  • the frame part in the axial direction offset from one another arranged ring sections Viewed in the circumferential direction, the frame part in the axial direction offset from one another arranged ring sections. That is, the frame member has a zigzag or wave-like profile, so that the radially outer ends of the bristles not in a plane, but in the circumferential direction, come to lie axially offset from one another.
  • Those in the axial direction offset from each other ring sections can be considered as elevated and recessed ring sections about when depositing the brush ring on a substrate.
  • the frame part further comprises connecting means formed in the axial direction, which are arranged symmetrically relative to one another with respect to a center axis extending through the entrainment device and the center of the ring.
  • the connecting means allow a direct connection of individual brush rings with each other.
  • the connecting means based on a lying brush ring, arranged on the axial top and / or bottom, so that adjoining, in particular superimposed brush rings can already be interconnected in rotation with each other.
  • the connecting means are arranged symmetrically to the center axis, the individual brush rings, for example, alternately, in each case in reverse orientation to the shaft are fixed, wherein the driving device is also formed symmetrically to the center axis to form a rotationally fixed connection of the brush ring and sweeping roller. That is, the brush ring is rotatably on the shaft both in an original as well as in a rotated by 180 ° about the center axis alignment.
  • the connecting means are also arranged symmetrically to the center axis, these also in an original, or identical aligned configuration of adjacent brush rings as well as in a rotated configuration correspond to each other and immediately provide an anti-rotation adjacent abutting brush rings.
  • the assembly process of the brush rings on the shaft can be simplified so that, for example, a predetermined number of brush rings already quasi preconfigured among themselves to form a brush ring package and bundled and can then be postponed as a package in one operation on the shaft. Also, individual brush rings can be accurately positioned and aligned with each other in this way before sliding on a common shaft.
  • the connecting means are formed symmetrically to the center axis.
  • the connection means should be more or less self-replicable to allow mutual placement of adjacent brush rings in an identical and / or 180 ° rotated orientation.
  • connection means are formed corresponding to one another with respect to the center axis of the brush ring.
  • a connection means located at 30 ° from the center axis may have a shape such that it corresponds to a connection means arranged at -30 ° on the brush ring, namely when a second brush ring of the same design is rotated through 180 ° about the center axis that first brush ring comes to the plant.
  • the connecting means have mutually formed axial positive locking means.
  • conical or dome-shaped projections as well as recesses and receptacles correspondingly formed therewith come into question.
  • spike-like projections which run in the radial direction and have a triangular cross section in the axial cross-section, and corresponding recesses.
  • the interlocking means may also form a kind of latching and / or cause a clamping action to facilitate the formation of brush ring packages and their handling.
  • the interlocking means may also form a kind of latching and / or cause a clamping action to facilitate the formation of brush ring packages and their handling.
  • the connecting means have at least one pin projecting axially from the frame part and, for this purpose, mirror-symmetrical to the center point axis, a recess corresponding to the pin.
  • the pin is tapered to form a clamping cone towards its end, and that the corresponding recess has at least one side cheek corresponding thereto.
  • a clamping action of the pin and the recess can also be formed, wherein adjacent frame parts with their axial side surfaces preferably come into direct contact with each other.
  • a mutual axial support is thus preferably on the side surfaces of the brush rings, while a torque-transmitting positive engagement of adjacent brush rings predominantly via interlocking pin and hereby corresponding recesses occurs.
  • a possible transmission of mechanical vibrations from a brush ring to adjacent brush rings can thus be counteracted.
  • a kind of vibration decoupling or vibration damping during operation of the sweeping roller thus created can be further provided.
  • the positive locking means with axial projections and recesses corresponding thereto extend substantially over the entire radial width of the frame part.
  • the axial height or depth of the projections, or the depressions can be reduced to a minimum with increasing radial width.
  • the advantage is namely to keep the axial extent of positive locking means as low as possible in order to minimize the mechanical stability of the frame part by the connecting or positive locking means.
  • the connecting means in such an on an axial upper side and on an axial underside, thus, arranged on both sides of the frame part, that the connecting means are each engageable with each other in an alternately rotated about the midpoint axis arrangement of a plurality of identical brush rings. It is also conceivable here that in a correspondingly symmetrical configuration of connecting means they can be brought into engagement even with a non-rotated arrangement of adjacent brush rings, so that the end user can always secure the frame parts with each other in the direction of rotation regardless of whether they are rotated about the center axis or are aligned identically to each other.
  • the connecting means are always arranged on the upper side of a raised annular portion and / or on an underside of a recessed annular portion.
  • the connecting means extend in the circumferential direction of the ring viewed over the vertex of an elevated, respectively a recessed ring portion. Between raised and recessed ring sections are usually no connection means provided.
  • the connecting means may be formed on each raised and / or each recessed ring section, but also only occasionally on some selected raised or recessed ring sections. It is also conceivable that in each case symmetrically or correspondingly mutually formed connecting means are provided on raised and recessed ring sections on both sides.
  • annular section when the entraining device which comes into operative connection with the shaft is arranged at the vertex of an elevated or recessed annular section, that annular section can also be provided with a connecting means formed symmetrically or corresponding to the midpoint axis.
  • raised and recessed ring portions are formed substantially convex and / or concave curved and merge directly into each other.
  • a possible harmonic, kink-free wave-like course is provided for the brush ring or for its frame part, which viewed in the circumferential direction has either a steadily increasing or steadily decreasing slope.
  • Such a harmoniously formed frame member can withstand the mechanical stresses occurring during operation sufficient, while experience can occur at kinks previously known brush rings under circumstances material fatigue and material weaknesses, such as in the form of fractures, come to light.
  • a connecting means is formed both at the top and at the bottom of a raised and / or a recessed ring portion. If approximately three raised and three recessed ring sections are provided, a total of six corresponding connection points, namely each at the raised and recessed ring sections, can be formed in a parallel arrangement of adjacent brush rings. In a configuration rotated by 180 °, the tops and bottoms of two adjoining frame parts then arrive at three points each for mutual engagement.
  • the connecting means has wave-like in the axial direction increased and recessed first positive locking means, each formed with second, in the axial direction as a pin and recess Positive locking means are provided.
  • first positive locking means each formed with second, in the axial direction as a pin and recess Positive locking means are provided.
  • two mutually corresponding positive-locking profiles of the frame part are geometrically superimposed.
  • the second designed as a pin and recess positive locking means but predominantly contribute to a clamping action and thus to a locking immediately adjacent to each other arranged brush rings.
  • the brush ring for the brush ring according to the invention, provision is made in particular for the latter to be alternately arranged around the midpoint axis in a first configuration of brush rings stacked with a plurality of identically configured and stacked in the axial direction, and in a second configuration in which brush rings to be arranged adjacently arranged are rotated by means of the connecting means. preferably with only one type connecting means are connectable to each other.
  • the invention further relates to a sweeping roller having a substantially cylindrically shaped, such as rotatably mounted in a sweeper shaft on which a number of the above-described brush rings by means of aligned mutually axially arranged entrainment means rotationally fixed to the shaft and by means of the connecting means described also are mounted directly rotatably with each other.
