The invention relates to a cleaning unit, in particular as accessories to cleaning-suction machine that contains at least one connected with the actuator and located on the rail, sweeping device, and the guide consists of several elements, some of which is fixed and the LASS="ptx2">

Such sweeping unit is known from the application France N 2652100 A1. He has two sweepers devices, each of which includes a brush fabric covering forming two corresponding guide ring with a vertical axis of rotation. One of the rollers is stationary, the second has the ability to rotate.

To reduce the width of the processing in a known unit both roller cleaning device, the position of which may vary, are aimed the same direction, i.e., forward, forward rotation.

Another known cleaning unit DD 269549 has a transversely directed roller with a horizontal axis of the brush, the canvas on each side of a centrally located suction nozzle. Both brush paintings can deviate in the horizontal plane in a V-shaped, open forward position so that the Assembly could pass through the narrow space. Guiding elements of both brush paintings, intended to move the canvas, unable to change its position relative to each other.

Both known for sweeping unit does not have the ability to automatically disconnect when confronted with an obstacle. Moreover, V is the image of the button to eliminate the clash between the outer ends of the brush paintings with limiters, forming an obstacle.

Known cleaning units are not provided as additional devices for cleaning-suction machine.

In contrast, the basis under consideration of the invention is to create a sweeping Assembly providing mechanical sweeping with variable width processing in the inner and outer area, so it can be carried out automatically change its shape.

The combination of the sweeping unit with any cleaning-suction machine is advisable. A special goal of this invention is to use a sweeper Assembly in combination with the cleaning-suction machine with variable width processing, which is the subject of German patent application P N 4103087. As the width of the cleaning processing-suction machine should be changed and the width of the processing sweeping unit.

This allows you to handle heavily soiled floors and/or floor, the purity of which are particularly high requirements. Currently cleaning such floors is carried out in such a way that first metalsusa machine from adhering thereto dirt. In many areas of application, for example, when cleaning floors in supermarkets and Department stores, it is impossible to refuse a preliminary floor sweeping before cleansing treatment. Otherwise, solid contaminants, such as glass fragments, can be captured rotating, cleansing the dirt, brushes and cause damage to floors, or they can cause damage made of soft rubber cleaning tapes cleaning unit, in addition to semi moist during the cleaning process, can be pasted paper for example, detached cashier's checks. Therefore, when cleaning floors need two operations: sweeping and cleaning, which should follow each other, which is associated with corresponding high costs.

According to the present invention, the above task in a sweeping machine according to the restrictive part of the formula of the invention is solved due to the fact that changing the length of the guide elements is made to decline or moved in the direction opposite to the working movement relative to the guide elements rigidly mounted on the respective cleaning device, reducing a width of Abramov, employees for directions and change the width of the sweeping device; as guide elements are considered, in particular, deflecting, presses, rollers, skids, guides, tires, etc. Cleaning device may include brushes for manual operation or motor-driven variety of execution known in the field of cleaning machines, for example, rotating around a vertical axis, plate, or rotating around a horizontal axis valicevic brushes, or with brushes, endless sweeping cloths.

If you are an endless cleaning cloth is expedient to provide at least two endless cleaning cloth (1) moving perpendicular to the guide elements.

However, changing a position of the guide inside the cleaning unit may be implemented in a variety of ways, for example, change their position, the guide elements can have the ability to reject such a way that they form a working direction changing angle, in addition, in the case of multiple guides for sweeping cloths they can be set is t to be due to the fact, they are designed with the possibility of changing the shape, i.e., so that the position of the individual elements of the guide may change relative to each other, making the canvas continuously moving sweeping cloths may take different positions: direct inward/outward or forward/backward curved. For this structural detail, the connecting elements of the guide, are of elastic material or in the form of links pivotally connected to each other. Perform cleaning device as infinitely moving cleaning cloth is particularly preferred when the guide provided, the form of which may vary, because that's the way it is particularly easy to fit along with the position of the guide and also the sweeper device to the desired width of the processing. In addition, running the brush as a sweeping canvas has the advantage that the detected dirt faster than in the case of roller brush device ( cleaning roller) and disc brushes served to narrowly limited area, in particular, to the place of rounding sweeping blade guide element; shall be accordingly reduced dimensions, that allows to reduce the required air suction, and thereby reduces the required power of the suction device. This is important especially due to the fact that the sweeping unit can operate in combination with independent network cleaning-suction machine with appropriately limited capacity of the batteries. Sweeping unit according to the invention preferably has at least two continuously moving the elements of the guide endless cleaning cloth supplied with the guides. It is necessary to provide at least one pair of sweeping cloths, in which sweeping cloths are working in opposite directions and dirt is supplied to the nozzle device, the host under the debris, located between two sweeping cloths one pair. In line with this, the designated rounding both sweeping cloths one pair are located adjacent to each other and close to the common suction nozzle. Thus, it is possible to a specified pair of sweeping cloths were connected, in particular, two other sweeping cloths with a deeper location, both front sweeping the possibility of movement and/or deflection in the direction; this allows each individual the guide itself is rigid, i.e., in particular, to construct so that all the elements of one of the guide was to a shared hard holder, which is mounted to the cleaning unit either rigidly or with the possibility of changing its position. Conversely, by themselves, the guides can also be made with the possibility of changing the shape, i.e., a separate guide elements can change their position relative to each other. Due to this, in this case, change the path cleaning cloth, guided by the guide elements. Holder, connecting the guiding elements is in this case expediently, of several sections, which are connected to each other.

When several guides provided endless sweeping cloths, they preferably can be performed independently from each other change their position.

This allows unilaterally to change the width of the processing, for example, when meeting with located on one side of the obstacle. Flexibility in choosing the optimal treatment width is significantly higher if the corresponding doctitle the form of the sweeping unit is provided, each sheet rounding sweeping cloths guide element is a suction nozzle, because not only the front in the direction of the plot sweeping canvas captures dirt, but the rear section transports the dirt in a known volume to the appropriate place following the guide element, because 100% performance sweeping technically cannot be implemented in the front area sweeping cloths. It is advisable to have in the area of each suction nozzle cleaning element, which rotates the brush sweeping cloths. He contributes to a better separation of the dirt from the brush, which can passivate nozzles of the suction device. However, the performance of cleaning may increase due to the fact that the brush sweeping cloths are installed at an angle relative to the direction of travel, i.e., the brushes have a forward tilt in the direction of movement sweeping cloths.

To receive the coarse particles of dirt when applying sweeping cloths may be preferable that the zone of the suction nozzle and/or directly along the back side of the cleaning cloth was installed scraper. When it comes to tselesoobraznosti together sweeping canvas.

In the working direction before sweeping paintings it is advisable to position separating the bracket, which when confronted with obstacles causes a change in position of the holder in respect of reducing the width of the particles zone. While there are various technical possibilities of implementation. So, for example, separating the bracket may be made in the form of the probe, which upon contact with an obstacle acts on the switch, which is the impact on pneumatic, hydraulic, etc. actuator to rotate or move the respective guide cleaning cloth. On the other hand, separating the bracket can be designed so that, in particular, in the units of small size it moves or turns directly related guide cleaning cloth in case of a collision with an obstacle, i.e. the corresponding guide under the action of an obstacle with which the collision occurred, so moves or rotates it, what will stop the possible passage of obstacles by sweeping unit.

In order to reduce the dustiness level, sweeping unit is on the La is drawn into the pump and through pressure pipelines, laid along the sweeping cloths, and many nozzles rasplivaetsa to the formation of fog.

Sweeping unit according to the invention can be mounted on the chassis, forming the actual sweeping machine. On the other hand, there is a particularly preferred ability to perform cleaning-suction unit with the changing width of the processing according to German patent application P 4103087 and tile cleaning unit according to the invention on a common chassis, allowing it turns out combined sweeping and cleaning-suction machine. Thus, the working width of the cleaning unit and the cleaning-suction unit match each other, i.e., the part of both units with variable length are interrelated. Especially suitable is the implementation of the sweeping unit according to the invention in such a way that there is a means of attachment for quick installation on cleaning-suction machine according to German patent application P 4103087. This used a high-speed tool for fixing cleaning unit for cleaning-suction machine is known from the prior art.
