Definitions
- the present invention relates to a sweeping unit, in particular as an additional device for a scrubber-drier, with at least one driven sweeping device arranged on a guide, the guide consisting of several elements.
- Such a sweeping unit known from DD 269 549, has a transverse brush belt, which is guided around rollers with a horizontal axis, on each side of a centrally arranged suction mouth.
- the two brush belts can be swiveled in a horizontal plane into a V position that is open to the front so that the sweeping unit can pass through narrow passages.
- the guide elements of the two brush belts each referring to a belt guide, cannot change position with respect to one another, so that automatic dodging when approaching an obstacle is not possible. Rather, the V-position of the two brush belts must be set accordingly before driving over an obstacle in order to avoid that the outer ends of the brush belts abut the boundaries forming the obstacle.
- the known sweeping unit is not provided as an additional device for a scrubber-drier.
- the present invention has for its object to provide a sweeping unit which enables mechanical sweeping with variable working width in the interior and exterior, so that its contour can be adjusted automatically and which can also be used in connection with any scrubber drier can be used.
- a particular object of the present invention is to use the sweeping unit in conjunction with a scrubber drier with a variable working width, which is the subject of the German patent P 41 03 087. Just like the working width of the scrubber drier, the working width of the sweeping unit should also be variable.
- this object is achieved in a generic sweeping unit in that part of the elements forming the guide is fixed to the sweeping unit, another part for changing the sweeping width of the sweeping unit is arranged in a variable position.
- the sweeper will understood the sum of the individual elements that serve to guide and adjust the width of the sweeping device; deflection, pressure, guide rollers, sliding surfaces, guide rails and the like are particularly suitable as guide elements.
- the sweeping device can comprise manually or motor-driven brooms of various designs known in the field of cleaning machines, for example disc brushes rotating about vertical axes or roller brushes rotating about horizontal axes or endless brush strips covered with bristles.
- endless sweeping belts are used, it is expedient that at least two endless sweeping belts (1) running around in an upright arrangement on the elements of the guide are provided.
- the position of the guide can be changed within the sweeping unit in a variety of ways; For example, the position-changing elements of the guide can be pivoted so that they enclose a variable angle with the working direction; furthermore, in the event that several guides provided with sweeping belts are provided, these can be moved sideways on the sweeping unit be stored; finally, the position of the guide can be changed by the fact that it is deformable in itself, ie the position of the individual elements of the guide relative to one another can be changed, so that the path of the revolving sweeping belt has a different shape (straight, inward) / curved outwards or forwards / backwards).
- the components connecting the elements of the guide can consist, for example, of a flexible material or can be constructed from articulated members.
- the formation of the broom as a revolving sweeping belt is particularly advantageous if a guide which is deformable in itself is provided; because in this way the position of the guide can also be adapted in a particularly simple manner to that of the broom required in each case.
- the design of the broom as a sweeping belt has the particular advantage that the detected dirt - more directly than with a roller brush (sweeping roller) and plate broom - is conveyed to a narrow area, namely the deflection point of the sweeping belt; the suction can thus be limited to this narrowly limited area, ie the suction mouth can be dimensioned accordingly small, which means that a low suction air throughput and thus in turn leads to a low power requirement of the suction unit.
- the sweeping unit according to the invention should also be operated in combination with a mains-independent scrubber drier with a correspondingly limited battery capacity.
- the sweeping unit according to the invention preferably has at least two endless sweeping belts rotating in a Hochkan arrangement on the elements of the guide, with associated guides.
- at least one pair of sweeping belts is preferably provided, in which the sweeping belts are driven in opposite directions with respect to one another and convey the dirt to a suction mouth arranged between the two sweeping belts of the pair of suction devices receiving the sweepings. Accordingly, a deflection point of the two sweeping belts of the pair are adjacent to one another and are arranged near the common suction mouth.
- two further sweeping belts are arranged in a staggered arrangement downstream of the above-mentioned pair of sweeping belts, the two front sweeping belts being fixed and the downstream sweeping belts being displaced and / or displaced sideways. are pivotally suspended from the sweeping unit; this makes it possible to form each individual guide rigidly, that is to say in particular to build up all the elements of a guide on a common rigid support which is either fixedly fixed in the sweeping unit or can be changed in position.
- the guides may also be deformable as such, that the individual elements of the guides • their position may change with respect to each other.
- the contour of the sweeping belt rotating around the guide elements changes.
- the carrier connecting the guide elements to one another expediently consists of several sections which are connected to one another in an articulated manner.
- a scraper hook against which the bristles of the sweeping belts run is expediently provided in the area of each suction mouth. They have the effect that the dirt loosens better from the bristles and can be absorbed by the suction mouths of the suction device.
- the sweeping performance can be further increased in that the bristles of the sweeping belts are inclined against their direction of rotation, ie that the bristles point obliquely forward in the direction of rotation of the sweeping belts.
- a scraper is provided in the area of the suction mouths and / or directly along the rear of the sweeping belt.
- This is expediently a customary one Band-shaped band-shaped elastic strip on the bottom surface, which can be changed in position together with the sweeping band.
- a deflector bar is expediently arranged in the working direction in front of the sweeping belts, which, when encountering an obstacle, changes the position of the carrier in the sense of reducing the sweeping width.
- the deflector bar can be designed as a pushbutton which actuates a switch when it encounters an obstacle, which in turn controls an electrical, pneumatic, hydraulic or similar adjusting device for pivoting or shifting the corresponding, assigned reversing belt guide.
- the deflector bracket in particular in the case of smaller sweeping units, can also be designed such that it immediately shifts or swivels the sweeper belt guide assigned to it when it encounters an obstacle, ie the corresponding guide is directly affected by the one striking the deflector bracket Obstacle shifted or pivoted until it is possible for the sweeping unit to pass the obstacle.
- the sweeping unit can have an additional misting system.
- the liquid to be nebulized is sucked out of a storage container by means of a pump and sprayed via pressure lines, which are laid along the sweeping belts and have a plurality of nebulizing nozzles.
- the sweeping unit according to the invention can be built on a chassis and thus forms an independent sweeper.
- a scrubber-drier unit with a variable working width according to German patent P 41 03 087 and a sweeper unit according to the invention on a common chassis so that a combined sweeper and scrubber-drier machine is created.
- the working width of the sweeping unit and the scrubbing suction unit are coordinated with one another, ie the parts of both units that are variable in position are coupled to one another.
- the fasteners to be used for the quick attachment of the sweeping unit to the scrubber drier are known as such in the prior art.
- FIG. 1 shows a plan view of a sweeping unit according to the invention in its state attached to a scrubber drier;
- FIG. 2 shows a section through the combined sweeper and scrubber-drier according to FIG. 1 along the line II-II;
- Fig. 3 shows a section through the combined sweeper and scrubber drier according to FIG. 1 along the line III-III and
- FIG. 4 shows a schematic top view of a variant of the sweeper.
- the scrubber drier after not being the subject of the present application, is shown with thin lines, whereas the sweeping unit according to the invention is shown with bold lines.
- the sweeping unit shown in the drawing has two endless sweeping belts 1, which have bristles 2 on their lower edges are equipped.
- the sweeping belts consist of a flexible, stretch-resistant band material or of articulated, chain-like elements.
- Each of the two reversing belts runs between a drive roller 3 and a deflection roller 4, which define the two deflection points.
- a drive motor 5 is provided in a lying arrangement, which is connected to the respective drive roller 3 via an angular gear 6.
- Two guide rollers 7 and guide surfaces 8 are additionally provided for guiding the sweeping belt.
- the suction unit comprises the suction tank 9 on which the suction motor 10 driving a suction fan (not shown) is constructed.
- a filter is installed on the suction tank as a separating device 11, which separates the dirt absorbed by the suction air from it and retains it in the suction tank.
- the front, central suction mouth 13 is between the two the front ends of the sweeping belts, where they rotate around the drive rollers 3, arranged.
- the rear suction mouths 14 are arranged immediately behind the deflection points of the sweeping belts, which are defined by the deflection rollers 4.
- the naturally aspirated motor is powered by a current source (not shown).
- the tension lever 19 can be pivoted about a vertical axis with respect to the links 18.
- a spring 20 arranged between each link 18 and the associated tensioning lever 19 pre-tensions the tensioning lever to such an extent that the sweeping belt 1 has its optimal tension.
- a strut 21 is provided on each tensioning lever 19 and serves to hold the respective outer, rear suction mouth 14.
- the sweeping device of the sweeping unit can be driven by motor or by hand.
- a gear can be provided for this purpose, which is usually coupled to the wheels of the pushed sweeping unit.
- a battery for the electric motor drive of the suction fan for the suction unit be provided.
- another pick-up device for the sweepings can also be considered, such as a bristle-covered pick-up roller, which conveys the swept sweeps backwards, preferably via a ramp that ends near the floor or grazes on the floor surface into a dirt hopper connected to it.
- a bristle-covered pick-up roller which conveys the swept sweeps backwards, preferably via a ramp that ends near the floor or grazes on the floor surface into a dirt hopper connected to it.
- Fig. 4 shows a plan view of the front 'half of a sweeper whose sweeping unit does not need a suction unit. Instead, it has a sweeping roller 25 which rotates about a horizontal axis 26 which runs transversely to the longitudinal axis 27 of the sweeper.
- the sweeping roller 25 conveys the sweepings detected between the front ends of the two sweeping belts 1 from bottom to top via a scraper strip 29 which ends at the bottom end with its end edge 28 and rises from there into a sweeping hopper 30 connected to it
- the upper drawing level is shown in the extended position, the lower one is shown in the pivoted position.
- Deflection roller 32 can be pivoted in accordance with double arrow P, as a result of which the variable sweeping width of the sweeper is realized.
- a stripper 33 with a dashed line is also drawn, which moves with the pivotable rear section of the sweeping belt.
