Abstract

A sweeping machine roller brush has a cylindrical central tube (10) which is provided with a plurality of axial guide bars having guides for supporting bristle bars (20) that are divided into sections. The bristle bar sections (28, 30, 32, 34) have mounted thereon a plurality of flexible plastic sleeves (22). The sleeves have bottom parts (22A) which are fitted into holes provided in respective bristle bar sections, and relatively long, upper free parts (22B) which are located radially outside the bristle bar sections. Bristle bundles (26) are fitted onto the plastic sleeves. Located between the upper parts (22B) of the plastic sleeves are intermediate walls (42) which function to prevent the passage of air between the sleeves as the roller brush rotates, so as to obtain a desired fan effect which blow away, for instance, newly fallen snow, even when the bristles are pratically totally worn. The partition walls are moulded integrally with the sleeves.

Description

Brush roller for a street sweeper.
The present invention relates to a roller brush as¬ sembly intended for sweeping machines and being of the kind defined in the preamble of the following main Claim.
An example of such roller brushs is found described in US,A,4 538 319.
Sweeping machines of the kind concerned are used, among other things, to sweep away snow from airports, to sweep-up leaves from streets and other surfaces, for cleansing railway tracks, etc. The bristle bundles of such roller brushs normally comprise steel wires of different dimensions, but may also comprise plastic wire, for instance when the brush is intended for cleaning railway tracks.
In the case of smaller sweeping machines, in which the roller brushes have a length of about 4 m for instance, the roller brush is supported at both ends in bearings. The brush drive means is mounted on one end of the brush, whereas the other end of the brush is free so as to enable bristle bars to be inserted into guide bars attached to the central tube, as described in the aforementioned U.S. Patent Specification. However, there are found larger sweeping machines equipped with a long roller brush or with two mutually coaxial roller brushes which together can have considerable length, e.g. a length of 8 m.
When the bristle bundles on the roller brush are new and lie relatively close to one another, the bristle bundles located along the guide bars will function as a fan blade which centrifuges-out air as the roller brush rotates, therewith blowing away loose snow or leaves, for example. During this type of work, it is not neces¬ sary for the bristle bundles to lie in contact with the surface being swept, and the bristles are thus not subjected to wear. This effect is also obtained with roller brushes in which the bristle bundles are dis¬ posed in axial rows, as described in US,A,3 751 745 and US,A,4 498 210. The arrangements known from these specifications, however, do not include plastic sleeves which form flexible supports for the bristle bundles in the manner described in US,A, 538 319 and in the preamble of the following Claim 1.
When the coating of the surface being swept is more or less solid, such as ice crusts, packed snow or a rubber coating on aircraft runways, it is necessary for the bristles to be in contact with the surface being swept, therewith resulting in gradual wear of the bristles. The ability of the roller brush to function as a clean- blowing fan is also decreased to a corresponding de¬ gree. In some cases, the bristles are worn down to the vicinity of the plastic sleeves, and as a result there is obtained no fan effect at all, other than that produced by the outwardly jutting plastic sleeves.
These sleeves, however, are separated by a gap, and a substantial part of the air will flow through the gaps along a relatively long guide bar instead of being centrifuged-out and blown onto the surface being swept.
The object of the present invention is therefore to provide, with the aid of simple means, a roller brush which will produce a considerably better fan effect than earlier roller brushes when the bristle bundles of such brushes become worn to a greater or lesser extent. This object is achieved with a roller brush which has the characteristic features set forth in the following Claim 1.
Because each bristle bar is comprised of separate, se¬ quential sections and each brush-bar section carries a predetermined number of plastic sleeves, each of which holds a respective bristle bundle, and are mutually connected by partition walls between those parts there¬ of located externally of the bristle bar, there is ob¬ tained a fan wheel which effectively throws out air, even when the bristle bundles are practically totally worn down.
A suitable exemplifying embodiment of an inventive roller brush will now be described with reference to the accompanying drawings.
Figure 1 is a schematic, axial section view of an inventive roller brush, although only the upper half of the brush is shown;
Figure 2 is an end view of a row of bristle bar sec- tions which together form a bristle bar in a guide bar and carry plastic sleeves provided with bristle bundles;
Figure 3 is an end view of a bristle bar section which lacks the provision of bristle bundles;
Figure 4 is a side view of the section illustrated in Figure 3; and
Figure 5 is a view from above. The roller brush comprises a cylindrical central tube
10 which is rotatably journaled with the aid of journal pins (not shown) provided on the ends of the tube in a known manner.
Securely fixed to the central tube by means of keying or wedging devices 12 are guide bars 14 which have guide grooves 16, 18 formed along their outer edge parts. These guide grooves are intended to receive sequentially a plurality of rectangular bristle bar sections 20 having upper and lower parts 20A, 20B.
Each of the bristle bar sections has provided therein a row of sequentially disposed holes into which the lower parts 20A of the plastic sleeves 22 can be inserted and locked with the aid of a locking wire 24, in a known manner, said locking wire also functioning to lock a folded-over bristle bundle 26 inserted down into the plastic sleeve.
The lower end part 22A of respective sleeves extends through the upper and lower walls 20A, 20B of respec¬ tive sections 20 and has a relatively short length, whereas the upper, freely lying part 22B of the flex¬ ible plastic sleeves, located above the upper wall 20B, is at least 1.5, preferably about twice as long as the lower part 20A.
In operation, the long sleeve part 22B forms a flexible support for the bristle bundles 26, which are therewith bent gently to one side when subjected to load.
In the illustrated embodiment, each bristle bar is divided into four mutually sequential sections 28, 30, 32, 34 with closely lying joins 36, 38, 40.
Each section has four plastic sleeves 22 carrying bristle bundles 26.
The reference sign 26A in Figure 2 indicates a worn brush, which in the illustrated embodiment consists of sixteen bristle bundles.
In order to ensure that an effective fan effect is obtained when the bristles become worn, the freely lying parts 22B of the plastic sleeves are mutually connected by means of plastic, axially disposed inter- mediate walls 42, which are moulded integrally with the four plastic sleeves. The outermost sleeves have a flange-like part 42A of one wall.
As will be seen from Figure 1, the parts 22B of the plastic sleeves and the partition walls 42 form a relatively large "fan blade". The illustrated embodi¬ ment includes sixteen such blades, which together provide the desired fan effect even when the bristles are worn, therewith enabling the swept surface to be blown clean with worn bristles, which extends the useful life of the bristles by a commensurate extent.

Claims

Claims
