BEAM RECEIVING DEVICE

BRUSHED BROOM FIBERS

  EQUIPPED WITH CLEANING MACHINES OR APPARATUS

  The invention relates to the technical sector of cleaning machines of the type

  with brooms used in particular for snow removal.

  It is known to design cleaning machines comprising a plurality of associated brush modules making it possible to define a sweep roller for carrying out maintenance work over large areas and requiring very specific characteristics of solidity with regard to the masses of products to

  sweep, that is, move from one place to another.

  This is, for example, the case for certain snow removal works that can be encountered at airports to avoid, following bad weather, stops in activities detrimental to the daily management of such sites or private places.

or public.

  We already know some realizations of brushes in rollers equipping

cleaning machines.

  A first embodiment is thus shown in Figures 1 and 2 of the drawings.

  The brushes fiber bundles are thus attached and fixed from a crown (1) fitted with overhanging radial cavities (la) allowing the introduction of a sleeve (2) associated with each bundle (3) ensuring their maintenance radial. Each bundle is integrated into said sleeve which bears on the outer face of the crown while being held in the cavity, while a peripheral ring (4) is attached externally concentric to the crown and passing through said successive sleeves to form a rigid link between the fiber bundles. This rod forms a splice (4a) at its ends so as to produce an external fixing and finishing belt. Such an embodiment is impractical to implement, of a long assembly. In addition, the installation of the peripheral belt is difficult to position, because it is necessary to cross the network of fibers which is inserted in the sleeves, obviously resulting in difficulties of constitution. In addition, the bond requires the formation of a splice, so that with the exception of the final moment of ligation, the fiber bundles are not properly maintained. Another drawback lies in the deterioration of the fiber bundles. The deterioration of one of them necessarily leads to the removal of the peripheral belt. This is a particularly annoying constraint, if one is aware of the rapid deterioration of the brushes with regard to the conditions of use of these products. The fragility of said beams is also observed due to the above-mentioned assembly. To remedy these major drawbacks, another solution has been proposed.

  shown in Figures 3 and 4 of the drawings.

  In this second embodiment, strips (5) in the form of modules are defined and profiled, on the one hand being positioned between special grooves (6a) formed on a support mandrel (6) defining the shaft of the brush roller. These modules made of plastic slide in said grooves. They are arranged with several cups (5a) or cylindrical receptacles enclosing the bundles (7) of fibers themselves crimped in a ring (8) of plastic material. Each ring (8) is forcibly engaged or snapped into the cups (5a) or receptacles. The advantage of this embodiment lies essentially in the conformation of very long strips deployed in fiber bundle receiving modules. So we can define and

  very quickly select module lengths as required.

  Said strips are thus distributed over the periphery of the receiving mandrels in a longitudinal plane. The change of a fiber bundle only requires the removal of a module and its protective zone to release said fiber bundles relative to the receptacle facing. If this technology is satisfactory with a view to carrying out rapid changes of the brushes, on the other hand its implementation remains very expensive. Indeed, the receiving strip made of elastomeric material or plastic material requires molds or high-cost manufacturing dies. In addition, the tape receiving mandrel must be specifically profiled with grooves or grooves receiving the strips, so that the cost of implementing this technology is a

brake on its development.

  Washer brushes are also known which include a one-piece perforated ring with a plurality of openings over the peripheral width and

  allowing the positioning of the bundles of brush fibers.

  From these observations, the applicant's approach was to seek and design another solution which is a very satisfactory compromise with regard to the requirements of manufacturing and assembly costs, to the requirements of

  quick change of damaged brush beams.

  These and other objects will become apparent from the following description.

  According to a first characteristic of the invention, the device for receiving bundles of brush fibers in rolls fitted to cleaning machines or apparatus is remarkable in that it comprises a plurality of modules mounted on a mandrel, each module comprising two identical rings. arranged on one of their faces with means and receptor anchoring cavities and for positioning the bundles of brush fibers, and in that the rings are assembled so that their means and cavities are opposite and define open chambers on the outer periphery of said rings, 1 0 and in that the bundles of brush fibers are held by sheaths allowing a loop-shaped portion to protrude from each bundle, and in that each sheath and each receiving chamber are arranged with complementary male-female anchoring means authorizing the maintenance and positioning of said sleeves between the rings, e t in that each ring is arranged with a complementary form of anchoring perpendicular to the cavities allowing the insertion of a means of

  radial retention of brush fiber bundles through the loop.

  These characteristics and others will become clear from the rest of the

description.

  non-limiting manner illustrated in the figures of the drawings.

  The brush roller according to the invention comprises in practice a plurality of modules (M) mounted on a shaft or mandrel (9) having a groove (9a) for receiving, guiding and positioning said modules arranged

with an appropriate keying.

  Each module according to the invention is arranged in the form of two identical rings (10-11) made of all suitable materials. Said rings are advantageously arranged on one of their faces with means and cavities for anchoring (1 Oa-1 la) receptors and for positioning the bundles of brush fibers (12). The two rings are intended to be arranged one against the other with their parts and cavities facing each other, using several elements

  assembly (13) distributed radially by means of suitable anchoring screws.

  The assembly of the rings thus makes it possible to define open chambers (14) on the outer periphery of the rings and not projecting internally, and allowing the reception of said bundles of fibers (12) of brushes. These are thus arranged with a sheath or sleeve (15) to allow the retention of the fibers (12a), which are turned over on themselves by protruding from said sleeve (15) at one end to form a loop (12b). Said fibers constituting the bundle are made of all materials, plastics, composite, metallic, vegetable or other materials. The sheath (15) is arranged on its periphery with complementary anchoring means (15a) which are capable of adapting and cooperating with complementary shapes (l Ob- 1 lb) established in the cavities (1Oa-1 la) receiving the rings. These complementary male-female anchoring means allow the retention and positioning of the bundles of brush fibers. In a non-limiting implementation, the sheath enclosing the brush fibers is arranged with grooves (15a) allowing its positioning relative to the complementary anchoring means, established for example in the form of a shoulder (10b-1b)

  semicircular in said cavities, the assembly constituting the male-

  female. As a variant, according to FIG. 10, the sheath can be arranged with hollowed out shapes (15b) or notches adjusting on protruding means

  (lOb-1 lb) complementary formed in the cavities of the rings.

  According to another arrangement, the rings (10-11) are arranged with a complementary form (16) of anchoring perpendicular to said cavities (1 Oa- 1 1 a) and allowing the insertion of a retaining means (17) radial bundles of broom fibers. This means (17) is a pin or key or equivalent capable of passing through the loop (12b) formed at the end of the fibers coming to bear against the receiving sheath (15), this means being positioned and centered on the cavity (16 ) above-mentioned correspondent. Thus by the invention, each bundle of fibers is doubly maintained, on the one hand by the sheath prepositioned on the cavities of said rings and by the complementary anchoring means passing through the end loop of the bundle of fibers. A very advantageous arrangement is thus obtained allowing a rapid change of the bundle of deteriorated brush fibers. It suffices to open the assembly screws of the two rings slightly, one relative to the other, to reveal an interval allowing the release of the bundle of fibers relative to its

  housing and its anchoring means, and to change it.

  The invention achieved is of low manufacturing cost and its implementation is rapid.
