EP2284319B1 - Waste collection vehicle with a cleaning device - Google Patents

Description

The present invention relates to a refuse collection vehicle having a cleaning device for cleaning a surface.

From the prior art known cleaning vehicles for roads or paths have sweeping systems, which usually have a sweeping roller and a suction and / or a sweeping roller with a ramp-like guidance for the debris to a receptacle.

From the EP 2 284 319 A1 a waste collection vehicle with a cleaning device is known, which shows the features of the preamble of claim 1.

DE 22 25 680 A1 discloses a refuse collection vehicle showing two front mounted on the bottom of the vehicle rigidly mounted receiving means that do not mesh with each other.

However, such cleaning vehicles have the disadvantage that the sweeping roller devices constructed complex and due to the interaction with the Extraction device, which is regularly mounted inside the cleaning vehicle, is integrated directly into the structure, for example, the bottom of the cleaning vehicle. This results in difficulties when replacing eg the sweeping rollers, so that the duration of maintenance and thus the cost of maintenance can increase.

Further, it would be desirable to combine the advantages of known refuse collection vehicles such as refuse collection vehicles and the benefits of cleaning vehicles.

It is therefore an object of the present invention to develop a refuse collection vehicle of the type mentioned in an advantageous manner, in particular to the effect that a cleaning device of the refuse collection vehicle is simple and easy to replace and the range of use of a refuse collection vehicle can be increased.

This object is achieved by a refuse collection vehicle having the features of claim 1.

For example, it can be provided that the cleaning device can be attached to the tailgate of the refuse collection vehicle instead of the located in the rear, fold-down bed of a waste collection vehicle. As a result, advantageously, the range of use of a conventional waste collection vehicle can be increased. The design of the cleaning device has the advantage that debris such. Rubbish or other impurities can be absorbed only mechanically. It is conceivable that only one receiving means in contact with the surface, wherein it is sufficient if there is an approximately regular recurrent contact with the surface.

It is possible that the first and the second mechanical receiving means of the cleaning device at least partially engage with each other and / or at least partially mesh with each other during rotation.

Advantageously, it can be provided that the first and / or second receiving means of the cleaning device is a sweeping roller and / or that the first and second receiving means are rotatable in opposite directions. Thus, for example, the first receiving means rotate counter to the direction of travel, while the second receiving means rotates with the direction of travel.

It is also conceivable that the first receiving means of the cleaning device on the surface for receiving debris is unrolled and / or that the debris from the first receiving means to the second receiving means of the cleaning device can be handed over and / or that the recorded debris can be forwarded by means of the second receiving means , From the second receiving means, the recorded debris can be forwarded, for example, directly into a receptacle. It may just as well be provided that e.g. a further receiving means or conveying means, such as a ramp or roller or screw conveyor or conveyor belt or elevator is provided.

It is further possible that the first and / or second receiving means of the cleaning device at least two sweeping strips with between the sweeping strips having intermediate spaces and / or that the second receiving means is at least partially disposed above the first receiving means. This results in the advantage that by means of the sweeping strips, which are arranged for example in the axial direction on a roller arranged transversely to the direction of travel, debris simply collected mechanically, so swept up and can be collected in the interstices. Until the engagement of the first roller with the second roller, the debris remains, for example, in the intermediate space and is transferred during the engagement of the two rollers of the gap of a sweeping roller to the other sweeping roller.

It is also conceivable that the cleaning device is modular and / or designed as an attachment or as a trailer or integrated into the refuse collection vehicle. Due to the simple structure and the mechanical Aufsammelart the cleaning device can be advantageously constructed compact and modular. In particular, it is possible to retighten the cleaning device or to arrange in the rear of a refuse collection vehicle and pick up already swept up debris.

It may moreover be provided that at least one exhibitable sweeping agent is provided on the cleaning device and / or on the waste collection vehicle, in particular that the sweeping means is a sweeping plate with opposite direction of rotation to the direction of travel. This has the advantage that e.g. On the roadside befindliches sweeping the cleaning device can be supplied in addition, whereby the efficiency of the cleaning device can be increased and the total swept width can be extended over the vehicle width.

It is possible for the refuse collection vehicle to have a tank and / or a container or a vacuum container for receiving the sweeping material, preferably for receiving the sweeping material forwarded by the second receiving means. Furthermore, the waste collection vehicle may have an additional conveying and / or pressing device for transporting and / or compressing the sweeping material.

Furthermore, it can be provided that the cleaning device is hydraulically and / or pneumatically and / or mechanically driven and / or that at least one receiving means is hydraulically and / or pneumatically and / or mechanically driven.

It is also conceivable that the cleaning device is dry and / or humid operated and / or that optionally an air filter unit is provided for exhaust air. For example, spray nozzles or spray devices may be provided to facilitate wet or wet cleaning. By the air filter unit, there is the advantage, for example, to be able to remove disturbed dust or the like from the exhaust air of the cleaning device. It is further provided that hydraulic and / or pneumatic lifting means are provided. These may be, for example, hydraulic and / or pneumatic cylinders, which are arranged on the cleaning device and allow movement relative to the refuse collection vehicle.

It is also possible that the cleaning device is pivotable relative to the refuse collection vehicle and / or that the cleaning device is interchangeable.

It is further conceivable that the coupling means comprise a standard interface and / or that the cleaning device can be coupled to the waste collection vehicle at a standard interface.

In particular, it can be provided that the cleaning device can be coupled or coupled to a tilting device of the refuse collection vehicle.

It is also possible that the refuse collection vehicle is a small vehicle for use on municipal roads, paths and / or places with low tonnage, smaller vehicle width, lower total weight or a large vehicle is for use on highways and / or high-tonnage high-speed motorways. Small vehicles can for example be used particularly advantageously in narrow streets and / or on sidewalks.

It is particularly preferred, if it is a combined sweeping and refuse collection vehicle, in which the e.g. in the rear bulk for waste collection, such as tilting garbage cans, is interchangeable with a modular cleaning device. This has the advantage that the mode of operation of the multi-purpose vehicle thus obtained can be easily and quickly adjusted.

Fig. 1 shows a schematic representation of a rear-mounted cleaning device 10 of a cleaning vehicle 20 and designed as a multi-purpose vehicle 20 refuse collection vehicle 20. The cleaning device 10 is modular and attached by means of coupling means 40 to the pivotable tailgate 22 and tilting device 22. The coupling means 40 comprise in Fig. 1 shown embodiment executed as a DIN frame standard interface 42 to which the cleaning device 10 is coupled. At this standard interface 42, a bed of waste collection vehicle 20, not shown, can be attached, which can be emptied by dumping, for example, garbage cans in the tailgate 22 by means of the bed.

The cleaning device 10 has a first and a second receiving means 12, 16, which are each designed as a sweeping roller 12, 16. The second sweeping roller 16 is located above the first sweeping roller 12 and is arranged with its axis slightly offset in the direction of travel forward relative to the first sweeping roller 12 in the cleaning device 10.

The sweeping rollers 12, 16 have a plurality of sweeping strips 13, 17, wherein the sweeping strips 13 of the first sweeping roller 12 mesh with the sweeping strips 17 of the second sweeping roller 16. Between the sweeping strips 13, 17 of a sweeping roller 12, 16 are each intermediate spaces 14, 18, in which the collected from the surface O debris can collect. In this case, the first or lower sweeping roller 12 rotates opposite to the direction of travel in a direction of rotation a and thereby collects debris in the intermediate space 14 in front of the sweeping strip 13 sweeping the surface O.

As a result of the rotation of the lower sweeping roller 12, the sweeping material is introduced upwards into the cleaning device 10 and transferred or entered into an intermediate space 18 of the upper sweeping roller 16, which rotates in the opposite direction to the sweeping roller 12 in the direction of rotation b. From there, the debris is forwarded to the upper area of the cleaning device 10 and transferred from there into the container, not shown, of the cleaning vehicle 20, e.g. sucked. This is particularly advantageous when the container of the cleaning vehicle 20 is a vacuum container.

By means of the hydraulic compensating means 30, the cleaning device 10 is placed on the surface O, for example in the cleaning operation, wherein unevenness in the ground can be compensated by means of the compensating means 30. The compensation means 30 has for this purpose in Fig. 1 when driving over the unevenness or depression of the surface O the height h1, which is necessary to keep the lower sweeping roller 12 employed against the surface O hired. In addition, the compensating means 30 are also designed as lifting means 30, so that, for example, at the end of the cleaning operation, the cleaning device 10 can be lifted or lifted from the surface 10.

Fig. 2 shows the in Fig. 1 shown schematic representation of a arranged in the rear of a cleaning vehicle 20 cleaning device 10 when driving over a bump in the surface O. In this case, the resulting height difference is compensated by the compensation means 30. The compensation means 30 has for this purpose in Fig. 2 when driving over the bump or bump surface O the height h2, which is necessary to keep the lower sweeping roller 12 employed against the surface O hired.

The compensating means 30 comprises at least one hydraulic piston 32, preferably a pair of hydraulic pistons 32, which are arranged on both sides of the cleaning device 10.

In principle, it is conceivable that instead of or in addition to the hydraulic compensating means 30, pneumatic compensating means 30 are provided. These may include, for example, pneumatic cylinders 32.

In this context, it is conceivable that the hydraulic and / or compensating means 30 comprise a control and / or regulating unit (not shown) or are in communication with a control and / or regulating unit which controls the hydraulic and / or pneumatic compensating means 30 with respect to the Height difference eg by surface irregularities controls or regulates. The control and / or regulating unit, which is not shown in more detail, can also control or adjust the lowering and raising of the cleaning unit 10 by means of the balancing and lifting means 30.

Fig. 3 shows a schematic representation of a refuse collection vehicle 20 with a cleaning device 10 for cleaning a surface O according to the in Fig. 1 and 2 shown embodiment. The cleaning device 10 is already explained above by means of coupling means 40 attached to the refuse collection vehicle 20.

In principle, the term of the refuse collection vehicle 20 is not intended to be limiting, but can also be implemented by other types of vehicles, as described below 4 to 6 should be clarified:

Fig. 4 shows a schematic representation of a refuse collection vehicle 20 in the embodiment as a flatbed with cleaning device 10. Again, the cleaning device 10 is attached by means of coupling means 40 rear side on the refuse collection vehicle 20. The waste collection vehicle 20 is designed as a flatbed.

Fig. 5 shows a schematic representation of a refuse collection vehicle 20 in the embodiment as towing vehicle with trailer 50 and cleaning device. In this case, the refuse collection vehicle includes a towing vehicle 60 with trailer 50. Am Trailer 50 is attached to the rear side by means of coupling means 40, the cleaning device 10.

Fig. 6 shows a schematic representation of a refuse collection vehicle 20 in the embodiment as a sweeper with integrated cleaning device 10th
