Abstract

Des véhicules connus pour l'élimination des déchets possèdent un conteneur de collecte disposé sur le véhicule derrière la cabine du conducteur et pourvu, à son extrémité côté cabine, d'une ouverture de remplissage, ainsi que deux bras pivotants munis d'un dispositif de prise et de basculement qui prend au moins un conteneur de déchets positionné devant l'avant du véhicule, le fait passer par-dessus la cabine du conducteur et le vide dans la région de l'ouverture de remplissage du conteneur de collecte derrière ladite cabine. Les véhicules connus nécessitent toutefois une grande hauteur de travail, qui précisément n'est pas souvent disponible lors de l'élimination des ordures municipales. Dans le but d'améliorer de tels véhicules, un support (39) est disposé sur le véhicule et les deux bras pivotants (25) sont fixés audit support (39) avec leur pivot (26) dans la région frontale supérieure de la cabine du conducteur (1).Known vehicles for the disposal of waste have a collection container arranged on the vehicle behind the driver's cabin and provided, at its end on the cabin side, with a filling opening, as well as two pivoting arms provided with a device for pick-up and tipping device which picks up at least one waste container positioned in front of the front of the vehicle, passes it over the driver's cab and empties it in the region of the collection container filling opening behind said cab. The known vehicles, however, require a large working height, which precisely is not often available when disposing of municipal waste. With the aim of improving such vehicles, a support (39) is arranged on the vehicle and the two pivoting arms (25) are fixed to said support (39) with their pivot (26) in the upper frontal region of the cabin of the conductor (1).

Waste materials

Description:

The invention relates to a vehicle for picking up and transporting waste materials with a collecting container arranged on the vehicle behind the driver's cab, which has a filling opening at its driver's cab end, and with a pair of swivel arms that have a pick-up and tilting device for picking up At least one waste container standing in front of the front of the vehicle is provided and moves the waste container that has been picked up over the cab and emptied in the area of the fill opening of the collecting container behind the driver's cab.

Vehicles of this type, so-called overhead loaders, are known, for example from DE-AS 11 82 592, DE-AS 11 42 311 or DE-AS 12 26 053. A variant is also known from US Pat. No. 4,096,959 which is provided instead of a pair of arms, only a swivel arm arranged on the side of the vehicle, which has a crossbar running transversely to the axial direction of the vehicle for receiving the waste containers. The The pair of swivel arms or the individual swivel arm are either articulated on the vehicle frame behind the cab and are designed in the shape of an arch or bow (DE-AS 11 82 592, DE-AS 11 42 311) or the swivel arm pair is in three parts and is also behind the cab the upper edge of the collecting container articulated (DE-AS 12 26 053). The advantage of a so-called overhead loader is that the waste containers can be accommodated in the front area and thus in the driver's field of vision. The previously known vehicles of this type, however, have the serious disadvantage that a considerable free space above the vehicle is required for the pivoting and emptying of the waste container which is often not available in the urban areas, either Tram overhead lines, telephone lines, but also low tree branches are present, which hinder the swiveling process.

The invention is based on the object of designing a vehicle of the type described above in such a way that clean emptying is effected and the predetermined permissible clearance space l located on the vehicle is only slightly exceeded even when pivoting and emptying a received waste collection container .

This object is achieved according to the invention in that a carrier is arranged on the vehicle which is separate from the collecting container and which is connected to the vehicle chassis and to which the pair of pivot arms is fastened with its pivot bearing in the upper front area of the driver's cab. The arrangement of the swivel bearing of the swivel arm pair in the upper front area of the driver's cab, in particular in the case of a lowered driver's cab, results in much shorter swivel arms compared to the previously known systems, which inevitably leads to a reduction in the space required for the swiveling process in the area above the cab . Here, however, ^" the cab doors remain free, so that unrestricted access is possible at any time. The arrangement of a separate carrier enables a structurally flawless connection without impairing the separability of the collecting container.

In a particularly advantageous embodiment of the invention, it is provided that the receiving and tilting device for the waste container, which is connected to the pair of swivel arms so as to be rotatable about a horizontal axis, is connected to the pair of swivel arms by at least one drive means which is connected to the receiving and tilting device Holds waste container approximately vertically aligned during the swivel path extending over the driver's cab and controllable means are provided for tilting the received waste container.

This ensures that nothing can fall out or flow out of the waste container during the pivoting process, so that the waste container that is picked up only tilts directly above the filling opening of the collecting container and thus not only reduces the drop height but also a targeted one and clean emptying is ensured for the environment. The drive means can in this case be designed mechanically, in which, by means of a transmission linkage, the pivoting movement of the pivoting device generated by the pivoting drive of the pivoting device can be transmitted simultaneously to the receiving and tilting device by mechanical means. The mechanical coupling takes place in such a way that the swiveling movement of the receiving and tilting device is synchronous with respect to the swiveling speed and opposite with respect to the swiveling direction. In the case of geometrically more complex swivel devices, in particular in the case of pairs of bow-shaped or angled swivel arms, such a mechanical coupling is relatively complex and leads to an increase in weight, so that a hydraulic drive means which acts directly on the receiving and tilting device should preferably be provided here , where the Control takes place as a function of the swivel angle of the swivel device via a correspondingly controlled supply and discharge of the hydraulic fluid.

in an embodiment of the invention it is therefore provided that the drive means is formed by at least one oil motor which is connected to the receiving and tilting device. By appropriately regulating the supply and discharge of the hydraulic fluid, the desired relative movement between the receiving and tilting device on the one hand and the pivoting device on the other hand can be achieved in order to maintain the vertical alignment of the waste container.

In another embodiment of the invention it is provided that the drive means is formed by at least one hydraulic cylinder connected to the pivoting device, which is preferably connected to the receiving and tilting device via a transmission linkage. Hydraulic cylinders are of simpler construction and have the advantage here that they can be fastened in parallel to the corresponding parts of the swivel device, for example the swivel arms. Particularly when the swivel device has to swivel swivel angles of 100 degrees and more from the receiving position to the emptying position, such a hydraulic cylinder can no longer be connected directly to the receiving and tilting device, but a transmission linkage must be provided here, which has a Conversion of the linear piston movement into a swivel movement of over 100 degrees allowed.

The use of hydraulic drive means has the advantage over mechanical drive means that one is independent of the geometrical shape of the swivel device or of the swivel arm pairs, since the energy supply to the drive means can take place via pipelines and / or hoses, which problem-free the contour of the swivel device can be laid in the following. When using a

A pair of swivel arms is advantageously arranged on each swivel arm, an oil motor or a hydraulic cylinder. When using hydraulic cylinders, these are expediently designed as double-acting cylinders, so that the required synchronism, ie. H. Movement of the pivoting device and the receiving and tilting device can be achieved with the same pivoting speed but in the opposite direction of rotation.

In an embodiment of the invention it is provided that the drive means for synchronization with the pivoting movement of the pivoting device is connected to a pump unit which can be driven via the pivoting movement of the pivoting device. This pump unit only serves to drive the hydraulic drive means of the receiving and tilting device and is itself driven by the swivel drive of the swivel device. The desired control of the pick-up and tilting device as a function of the pivoting angle of the pivoting device can thereby be accomplished in a simple manner. When using an oil engine, a corresponding unit working as a pump is provided. When using hydraulic cylinders, one or more hydraulic piston-cylinder units that can be actuated for the swiveling device are to be arranged on the vehicle.

In a further advantageous embodiment of the invention, it is provided that the drive means also forms the tilt drive, reversing means being provided, by means of which, after the emptying position for the waste container has been reached, the pump unit for synchronous control switches over to a pressure oil supply and the receiving and tilting device in Tilting position is pivoted and pivoted back into the vertical position, and then reset to synchronism control. This reduces the construction effort considerably, with advantage - for example when using hydraulic cylinders - can be exploited that due to the opposite pivoting movement with appropriate dimensioning of the hydraulic cylinders, these are in an end position when the tilting position is reached, so that for the tilting movement Emptying practically the full cylinder stroke is available again.

In a further embodiment of the invention it is provided that the pair of swivel arms is connected to means which bring about a reduction in the total radius given by the pair of swivel arms and the waste container received, at least in the area above the driver's cab. In an embodiment according to the invention, the means can consist of extensions which are guided telescopically on the pairs of swivel arms and to which the receiving and tilting device is connected. In another advantageous embodiment, the means can be formed by a pair of guide arms connected to the free ends of the pair of swivel arms.

In a particularly advantageous embodiment of the invention, it is provided that the pair of guide arms is arranged so that it can pivot between the free ends of the pair of swivel arms and is kept aligned by the guide means essentially against the vehicle and at a constant angle with respect to the horizontal during the entire swivel path. With such an arrangement, it can be achieved, in particular on vehicles with a lowered driver's cab, that the pivoting process into the emptying position, but in particular also the tilting of the received waste container for emptying, requires a free space which corresponds to the height of the collecting container permitted by the height of the collecting container Vehicle does not exceed or only slightly exceeds. Another advantage of this arrangement is that the guide means can be designed much more simply by virtue of the vertical alignment of the receiving and tilting device during the pivoting path extending over the driver's cab is effected. The arrangement of the pair of guide arms which can be swiveled between the free ends of the pair of swivel arms allows this guide means to be assigned to the articulation region between the free ends of the pair of swivel arms and the pair of guide arms, while the tilt drive is then in turn mounted on the pair of guide arms. This results in a decoupling, which leads to considerable structural simplification.

In a particularly advantageous embodiment of the invention, it is provided that the drive means for the vertical guidance of the waste container by at least one first gearwheel which is fixedly arranged on the receiving and tilting device or on the pivot bearing of the pair of pivoting arms and by means of a pair on the pivot point of the receiving and tilting device or of the pair of guide arms fixedly connected second gear is det gebil¬ which is connected via a positive endless traction means, in particular a chain with the first gear ^'. When the pair of swivel arms is pivoted, the chain rolls on the fixed gearwheel and thereby pivots the receiving and tilting device or the pair of guide arms relative to the pair of swivel arms. Through the choice of the transmission ratio between the first gear and the second gear, depending on the dimerisioning, a "leading" or "lagging" of the relative movement of the pair of guide arms with respect to the pair of swivel arms can also be brought about, however, the alignment of the pair of guide arms should remain essentially in the room. With gear wheels of the same size, there is accordingly a constant alignment of the pair of guide arms in space during the entire pivoting process, so that even a waste container that has been picked up remains vertically aligned until the end of the pivoting process, so that the tilting process is only initiated by the tilting drive when the waste container is above the fill opening. Expediently are on each

Corresponding gears and endless chains are arranged in order to achieve the greatest possible utilization of the system with regard to the weights to be mastered. In a further advantageous embodiment of the invention, it is provided that the pair of swivel arms is pivotally connected to the support via a pivot bearing about a vertical axis. This arrangement has the advantage that the waste container to be accommodated is not only one

Position in front of the driver's cab but also from a position next to the lane of the vehicle. This offers the possibility of placing the waste containers to be picked up in a row next to one another and driving along the row with the vehicle and one after the other Another advantage of this arrangement is that such a vehicle is also able to load a second collecting container carried on a trailer, which is particularly important It is then advantageous if larger quantities of waste have to be collected in rural areas or special waste in addition to normal waste. For this purpose, the trailer with its special waste container is placed next to the vehicle, so that the normal waste is then placed in the container on the vehicle and which contains the special waste existing waste container can be emptied into the adjacent collecting container of the trailer or a second vehicle.

In a further embodiment of the invention it is provided that the pivot bearing is connected to the carrier so as to be displaceable in the longitudinal direction and / or in the transverse direction to the vehicle. The displaceability given in addition to the possibility of pivoting the swivel arm pair about a vertical axis offers the advantage that distance changes in the horizontal direction can also be carried out with the entire system without having to move the vehicle itself. This is advantageous both for holding the waste containers in the front area and in the side area of the vehicle and also for use when a waste container is to be emptied into a collecting container located next to the vehicle on a trailer. It is useful here if the rotary Bearing is connected to the carrier displaceably in the longitudinal direction of the vehicle and the pivot bearing is connected to the pivot bearing so as to be displaceable transversely to its axis. Here, too, there is a decoupling of the individual movement elements which simplifies the construction, so that here too the associated drives for the movement, for example hydraulically actuatable piston-cylinder units, can be arranged in a simple manner.

From US Pat. No. 4,096,959 and EP-A-0 163 859 a further vehicle with a pair of swivel arms for receiving waste containers in the front area is known, in which a hopper interacting with a press is arranged behind the driver's cab instead of a directly fillable container is the discharge opening with the filler opening detachably with the

Vehicle connected collecting container is connectable. The swivel arm arrangement according to the invention can advantageously be used in particular for vehicles of this type with a detachable collecting container. However, in order to be able to carry this out, additional measures must be taken in this area for the "clean" operation that is aimed for. In a further inventive embodiment, but not limited to the arrangement of the swivel arm pair with the receiving and tilting device according to the invention, it is therefore provided that the discharge opening has a tubular extension through the filling opening arranged in the lower region of the end wall of the collecting container extends into the collecting container, and that sealing means are provided, by means of which the tubular extension can be sealed off from the filling opening. With this arrangement, a perfect seal between the press and the detachable collecting container is possible, since the gap between the tubular extension and the filling opening is sealed and no waste can come out of the collecting container. All side surfaces of the tubular extension are expediently covered by sealing elements, so that the sealing means also extends over the entire circumference. The sealant can also be designed as a spring-loaded flap, which acts at least on the top of the tubular extension.

The arrangement of a channel-like protective cover in the interior of the collecting container, in particular if it is provided with a preferably pivotable locking plate, as specified in different configurations in claims 15 to 18, allows the collecting container to be detached properly from the vehicle without that something can fall out of the container. The collecting container is pulled off a piece of the press, but only to the extent that the tube-like extension is still with its free end in the filling opening. Then the locking plate is pivoted in. This can be done from above, from below or through two partial locking plates arranged in the manner of a door wing on the side walls of the protective cover. If the pivoting in the closing direction takes place in the same direction as the filling stroke of the press, this can be used for actuation, so that only corresponding locking means for the locking plate are to be provided on the collecting container, which should also be operable from the outside. The locking plate can also be designed to be releasably connectable to the front surface of the press ram on the one hand and to the channel-like protective cover on the other. The locking plate remains connected to the press ram during filling. After completion of the filling, the locking plate is inserted into the channel-like protective cover, locked there and at the same time released from the press ram and moved back again. The lock door can then also be closed.

With a corresponding design, both in the case of a pivotable design of the locking plate and in the case of an insertable locking plate, this can make an additional door in front of the filling opening unnecessary.

In a further embodiment of the invention it is provided that the tubular extension of the discharge opening of the rubble funnel is assigned a functional device provided with a drive, which has driver means which can be connected to a corresponding catch of a closure door for the filling opening which is guided vertically on the collecting container. This arrangement offers the possibility of transporting the collecting container completely closed, both empty and filled. The empty collection container is pushed onto the vehicle from behind or the vehicle travels under the collection container, which is raised on legs. The driver of the functional device then intervenes so that the closure door of the filling opening can be opened and the tubular extension of the opening can be inserted. The filled collecting container is released from the vehicle in reverse order. The collecting container is shifted so far back that the extension of the discharge opening is completely pulled out of the filling opening, so that the closing door can then be closed via the functional device. The particular advantage of this arrangement is that no drive devices are required on the collecting container itself, but that they are connected to the vehicle and can be driven via the energy supply of the vehicle. The drive can be formed here, for example, by a piston-cylinder unit connected to the driver or also by a circulation chain connected to the driver, which can be driven by a hydraulic motor. Appropriate drivable actuation elements are expediently also provided on the functional support, by means of which the actuating and / or locking means of the locking plate on the channel-like protective cover in the collecting container can be acted on. With a corresponding coupling of the controls, a fully automatic operating sequence can be achieved in which the functional sequences are linked together.

In a further embodiment of the invention it is further provided that a movement device is arranged on the vehicle, which is connected to a drive and via which the container when picking up and putting down at least one

Part of the way is movable. This movement device can be formed, for example, via a gate-like angle arm with a hook, a so-called hook lift, which is arranged on the vehicle so as to be pivotable and longitudinally displaceable and which engages around the filling opening. The particular advantage of the hook lift is that the collecting container can also be emptied by tilting it when it is locked at the rear end. The recording process is designed in such a way that when the last part is picked up and the first part of the movement path is set down by a shift in the longitudinal direction of the vehicle, so that the tubular extension of the hopper can be inserted or released correctly. The movement device can also be formed by a longitudinally displaceable carriage on the vehicle, which is provided with vertically aligned pins which can engage in corresponding recesses on the collecting container, so that the collecting container is placed on the vehicle via lifting devices or the like and then in its final position will be moved with the introduction of the tubular extension. This system is particularly suitable for those cases in which the receptacles to be picked up and put down are on legs so that they are driven under by the vehicle and then via appropriate in-vehicle facilities

Changes in the vehicle height can be added or removed. It is particularly expedient if the functional device is arranged on the movement device.

In a preferred embodiment of the invention it is further provided that the carrier for the swivel arm pair is fastened to the vehicle chassis behind the driver's cab. This arrangement has the advantage that the necessary rigid connection between the vehicle chassis and the carrier is not impaired by other internals, in particular not by the engine suspension. However, this embodiment, on the other hand, allows the carrier to extend beyond the driver's cab 1 extend so that neither the all-round view from the cab nor free access to the cab are impaired by the swivel arms and the carrier.

5 In a further advantageous embodiment of the invention it is provided that the carrier by means of a three-point support

%, is attached to the vehicle chassis, with two adjacent attachment points being fixedly connected to the vehicle chassis, based on the vehicle longitudinal axis, and

10 the third fastening point is articulatedly connected to the vehicle chassis. This arrangement has the advantage that the carrier, which is rigid in itself and is to be firmly connected to the vehicle chassis, does not impair the twisting of the vehicle chassis about the longitudinal axis.

It is particularly expedient here if the articulation of the third attachment point is arranged in the region of the longitudinal central axis of the vehicle chassis, so that this articulation point practically does not make any transverse movements when the vehicle chassis is twisted. It is particularly useful here

20 if the two rigid attachment points are arranged in the area adjacent to the driver's cab, while the third attachment point is arranged at a distance from it in the direction of the rear of the vehicle. Another advantage of this three-point support is that here also the above in ^•

25 Operation via the tipping moment initiated to be handled is reliably started.

In a further advantageous embodiment of the invention it is provided that locking means for fixed on the carrier

30 coupling of the collecting container are arranged. such

Locking means, which can be formed, for example, by pins and / or hooks arranged on the carrier, which engage in corresponding recesses in the front area of the collecting container, ensure that the carrier on the one hand

35 and the collecting container on the other hand form an essentially rigid unit, so that practically no, at least no disturbing relative movements between the collecting container and the tube-like extension of the hopper protruding into it through the filling opening. The locking means are expediently provided with actuating means, for example in the form of hydraulic cylinders or the like. Furthermore, the coupled collecting container ^• absorbs part of the tilting moment in the area of the articulated fastening point due to its weight, which relieves the load on the vehicle chassis in this area.

In a further advantageous embodiment of the invention it is provided that the drive means for the press of the hopper are also mounted on the carrier and the press ram is guided. Since the carrier has to be designed as a practically rigid unit anyway, this measure results in the press ram being guided free of distortion.

In a particularly advantageous embodiment of the invention, it is provided that the carrier is designed as a box construction, the hopper and the side walls being part of the supporting carrier construction. This arrangement has the advantage that, while saving weight, a rigid construction is created which can absorb both the load during the operation of the swivel arm pair and the load when the press is actuated.

In a further embodiment of the invention it is provided that the hopper runs upwards into side walls which essentially extend beyond the driver's cab to the front area. This arrangement has the advantage that when the waste container is pivoted upwards, it is already shielded from the side before its emptying point, so that in the case of dusty contents, dust escape under the influence of wind is reduced to a minimum.

In a further embodiment of the invention it is provided that a guide for a sliding cover is provided on the upper edge of the two side walls. Since the invented The design of the swivel arm pair in accordance with the invention allows it to be pivoted back so far without a waste container over the hopper that its free ends lie below the upper edge of the collecting container, the arrangement of a cover offers the possibility in pure driving operation, for example in the area of use or to pick-up and drop-off locations for the detachable collection container, to cover the entire arrangement and thus to shield it from the weather. It is expedient here if the rear end of the guides forms a cover that can be swiveled up. As a result, the free space above the hopper for the emptying process is increased and at the same time the hopper is still partially shielded without the free space for the emptying movement being impaired. Even during the collecting operation, in the event of heavy rain, at least the area above the hopper can be temporarily shielded by the cover, so that rainwater entering the collecting container is reduced to a minimum.

In a further advantageous embodiment of the invention it is provided that in the area of the rear end of the vehicle chassis a cross-member for supporting, guiding and locking the collecting container is arranged, which is pivotably mounted about a pivot axis running in the longitudinal direction of the vehicle, preferably the pivot axis, aligned with the hinge axis of the third attachment point of the carrier. This embodiment has the advantage that despite the practically rigid coupling of the rigid container itself to the carrier, which is also rigid, the

Vehicle chassis can twist in the intended manner about the longitudinal axis while driving, without this resulting in constraints between the collecting container and the vehicle chassis. The collecting container is thus also connected to the vehicle chassis in a three-point support, the two front support points being formed by the fixed support points of the carrier on the vehicle chassis during the third point of support through the

Swivel bearing of the crossbar is formed. The traverse the Quer¬ supporting joint ^'can in this case be formed by a ball joint.

In an expedient embodiment of the invention, it is further provided that at least one positioning spring element which is effective between the crossbeam and the vehicle chassis is provided. This ensures that, in the unloaded state, the cross-beam, which is provided with guide rollers and / or locking elements for the collecting container, is aligned horizontally with respect to the vehicle chassis, so that when the collecting container is received or driven under, its bottom rails are exactly in the guide rollers can intervene.

The structure of a vehicle equipped according to the invention is explained in more detail with reference to schematic drawings. Show it:

The vehicle shown in FIG. 1 for picking up and transporting waste materials is provided with a lowered driver's cab 1, so that a larger free space is available above the driver's cab. A collecting container 2 is also releasably arranged on the vehicle and is fastened by means of pins or closures 3. After loosening the closures 3, the collecting container 2 can be put down in different ways from the vehicle. This can be done either by the fact that the collecting container 2 has supports which can be extended downwards and are shown in more detail in FIG. 12, so that the vehicle, which has a device for lowering is equipped, can move away from the elevated container after lowering. The recording then takes place in reverse order, as will be explained with reference to FIGS. 12 to 15.

However, it is also possible to Fahrz ^'first eug additionally provided with a so-called hook lift to be provided, through which a aufgenomme¬ ner collecting container a short distance to the rear is moved horizontally and is then pushed by pivoting the lift hook further to the rear, so that the

Vehicle as soon as the rear edge of the collecting container touches the ground, can move forward while pivoting the lift hook further, and can thereby place the collecting container on the ground. An empty collection container is picked up in the same way. Such hook-lift constructions are known and their structure need not be explained in more detail here. The arm carrying the hook must, however, be designed in the shape of a bow so that it engages around the discharge opening of the hopper.

Another possibility is to provide the vehicle with a so-called tipping bridge, which is equipped with a cable winch, so that after releasing the locking and again moving the collecting container in the horizontal direction backwards, the tipping bridge swings up and the The collecting container can be lowered over the inclined tipping bridge with the help of the cable winch until the rear edge of the collecting container touches the ground again and the vehicle can drive forward while lowering until the collecting container finally rests on the ground. The recording is done in reverse.

The arrangement of a tipping bridge makes it possible, if a hydraulic lifting device is provided instead of a cable winch, to erect the collecting container vertically on its rear face instead of when it is set down on its bottom face. It is only necessary to do this at Swing up and lower the collection container at the same time to pivot the tilting bridge to the 90 ° position as soon as the lower rear edge of the collection container stands on the floor. The vehicle then drives backwards accordingly. The recording takes place in reverse order.

The rear end wall 4 of the collecting container 2 is designed in the usual way as a lockable flap, so that the contents of the collecting container can be emptied by tipping over after the lock has been opened. The collecting container can also be designed in such a way that the front end wall 5 is designed as an emptying flap and can be completely folded up for emptying.

On the front end wall 5, a filling opening 6 is provided in the lower region, which can be closed via a door 7 attached to its outside, for example a vertically displaceable and lockable sliding door.

On the vehicle itself, a press is arranged in the space between the driver's cab 1 and the end wall 5 of the collecting container 2, which has a hydraulic press cylinder 8 and a press ram 9, which is shown here in dashed lines in the press position. The press also has a hopper 10, the discharge opening through a tubular

Extension 11 is formed, which is dimensioned such that it protrudes through the filling opening 6 of the collecting container 2 in this. If waste is now thrown into the hopper 10 when the ram 9 is withdrawn, it can be pushed into the collecting container 2 via the ram 9 through the tubular extension 11 of the discharge opening of the hopper 10. As will be explained in the following, the tubular extension is associated with a channel-like protective cover 66 in the collecting container which surrounds the edge of the filling opening and into which the extension 11 is inserted. This not only allows the arrangement of seals that cover the gap between extension 11 and protective cover 66 at least over part of the Seal the circumference, but also the arrangement of an additional locking flap inside the collecting container, in order to prevent part of the container contents from escaping when the collecting container 2 is released.

On the inside of the end wall 5 of the collecting container 2, a swiveling flap 12 extending over the width of the filling opening can also be arranged above the filling opening 6 and is dimensioned such that it rests on this when the extension 11 is inserted. If the collecting container 2 is now withdrawn, the flap 12 swivels downward and covers the upper area of the filling opening 6 and secures it against falling out of the container contents until the door 7 is closed.

The hopper 10 runs upwards into side walls 13 which extend essentially beyond the driver's cab 1 into the front area. In Fig. 1, the front side wall is not shown to simplify the illustration. The upper edges 14 of both side walls are provided with a guide for a displaceable and preferably windable cover 15, so that the space above the driver's cab and the press can be completely closed during operation, via a displacement drive 16, for example one Winding device, this space can then be opened by pulling back the cover 15. The end 17 of the guides 14 which is adjacent to the winding device 16 is expediently designed in such a way that it can be pivoted up when the cover is withdrawn, as shown in broken lines. On the one hand, this increases the free space required for the swiveling and pouring process, as described in more detail below, and on the other hand, however, covers the opening of the hopper 10 to a certain extent, so that, for example, the entry of rain largely into the hopper during rainy weather is prevented. If the cover 15 is pulled back completely, an additional cover plate must be provided for shielding. The vehicle described with reference to FIG. 1 is now for the

Changing the collecting container 2 is designed so that the collecting container 2 is provided with downwardly extendable supports (not shown here), the vehicle itself being able to be lowered by a small amount to release the container after the closures 3 have been opened and thus below Can drive out container. In order to facilitate the insertion of the tubular extension 11 into the filler opening 7 of the collecting container in a vehicle of this type, the vehicle has a slide 18 provided with a hydraulic cylinder as a drive, which on the vehicle has a displacement of approximately 50 to 100 cm is slidably mounted, as shown in FIG. 2. The carriage 18 carries the front closure 3, which is designed as a driver. If the carriage 18 is now in its rearward position, the vehicle can drive under it in a lowered state in order to receive an elevated collecting container 2 until the front closure element on the collecting container 2 is approximately over the closure 3 of the carriage 18. Then the vehicle is raised so that the closure 3 engages in the closure element on the collecting container 2 and the closure 3 is closed. Now the carriage 18 is moved forward so that the tubular extension 11 can enter the filling opening 6 when the door 7 is open. This process is shown in its sequence in FIGS. 12 to 15.

In order to automate the opening of the door 7 here, a functional device 19 is now provided on the vehicle, for example in the form of an endless chain or a toothed belt 20, which is provided with a driver 21. The chain 20 can be driven via a drive 22, for example a hydraulic motor. The door 7 of the filling opening 6, which is designed as a sliding door, now has a corresponding catch, in which the driver 21 can engage, so that when pushed over the slide 18, the catch 21 first engages in the catch of the door 7 and via the functional elements direction 19 opened the door by moving upwards can be. The carriage 18 then moves forward until the extension 11 is inserted through the filling opening 6 and the rear end of the container can also be locked with the associated closure 3.

It can also be expedient in this system if the functional device 19 with the slide 18 constitutes a structural unit, so that when a collecting container is received in the manner described above, the catch of the door 7 already engages in the driver 21, even if the one with the Carriage 18 connected closure 3 is locked. The door 7 can then be opened before the collection container 2 is moved by the carriage in the direction of the tubular extension 11 of the press. Actuating elements for the actuating and closing means of a locking plate arranged in the collecting container can also be arranged on the functional device accordingly.

In the case of an embodiment with a hook lift, the structural component for horizontal displacement, which is customary in such a system, replaces the slide 18 described above until final locking. The lift hook is correspondingly frame-shaped, so that the tubular extension 11 of the press 7 is open in the operating state its outside is covered. In this system, the functional device can be in the angled, i.e. part of the lift hook pointing upward in the operating state.

In Fig. 3, a device 23 for receiving and emptying a waste container 24 is now shown and described in connection with the vehicle described above. All the elements which have been explained in detail above and are not necessary for the explanation of the function of the device 23 are omitted in FIG. 3 for reasons of simpler illustration. The device 23 is formed by a pair of swivel arms 25, the swivel arms of which are arranged parallel to one another and at a distance from one another which is approximately the width of the cab 1 corresponds. The pair of pivot arms 25 is provided with a pivot bearing 26 in the front region above the Fah¬ rerhauses 1 on a wearer ^'arranged 27th The swivel arm pair 25 is provided with a swivel drive which is designed such that the swivel arm can be swiveled over an angle of approximately 180 ° from the lower receiving position shown into the upper rest position 25 'shown in dashed lines. The swivel drive can be formed, for example, by one or more hydraulic piston-cylinder units, it being possible to achieve the required swivel angle via corresponding lever arrangements. This will be shown in more detail in FIGS. 4 to 6. It is also expedient to design the swivel drive in the form of a so-called hydraulic swivel motor. Here, two telescopically inserted shaft-piston elements with wide helical teeth are hydraulically axially displaced. The axial movement is converted into a rotary movement by means of an internal toothing which is fixed to the housing and which interacts with the toothing of the shaft.

In the embodiment according to Fig. 3 is the pair of swivel arms 25 is now connected to a guide means 28 which carries a receiving and tilting device 29 for the waste container 24 .. The guide means 28 is designed so that while extending over the cab 1

The swivel path of the waste containers 24 remains approximately vertically aligned, namely until the pair of swivel arms has been swiveled up into the fully extended emptying position 25 ". In this position, the receiving and tilting device carrying the waste container 24 is moved via its own tilting drive, not shown here , for example, a hydraulic piston-cylinder arrangement mounted on the guide means is pivoted into the illustrated emptying position so that the container contents can fall into the hopper 10 of the press 7. The representation of the device 23 in three different positions of its swivel path reveals that the waste container 24 is swiveled with its guide means between the pair of swivel arms when it is being picked up and over the entire swivel path, so that the necessary free space is practically over the free end 30 of the two swivel ¬ arms is limited, so this area is never significantly exceeded either by the pair of swivel arms or by the container. The illustration in FIG. 3 also shows that the free space required by the device 23 during operation only slightly exceeds the height predetermined by the upper edge of the collecting container 2, so that a clearance profile of less than 4.3 can be maintained.

In the exemplary embodiment shown, the guide means 28 is formed by a pair of guide arms 31, each guide arm being articulated at the free end 30 of a swivel arm 25. The receiving and tilting device 29 is in turn mounted with its tilt drive on the free ends of the pair of guide arms 31. The pair of guide arms 31 is connected to the pair of swivel arms 25 in such a way that it remains aligned essentially against the vehicle and at a substantially constant angle with respect to the horizontal throughout the entire swivel path, as can be seen from the drawing. For this purpose, a drive is provided, which essentially consists of a gear 32 fixed in the pivot plane of the pair of pivot arms 25 on the pivot bearing 26 and in each case correspondingly of a gear 33 fixedly connected to a guide arm. Both gears are each connected to one another by an endless chain 34, so that when the pair of swivel arms 25 is pivoted up, the chain 34 "rolls" on the fixed gear 32. Since both gearwheels have the same diameter, the gearwheel 33 and thus the associated guide arm are hereby held in the same orientation with respect to the vehicle as the fixed gearwheel 32 Gear diameter can now be provided a "translation" which causes a more or less strong change in the orientation of the pair of guide arms with respect to the vehicle, so as to be able to undertake the "geometry" in particular for the area of the emptying position 25 '.

3 also shows that, in the rest position 25 'shown in dashed lines, the device 23 as a whole can be pivoted within the space defined by the side walls 13 above the driver's cab 1. This makes it possible, as already described above with reference to FIG. 1, for the pure driving operation to completely cover the device 23 after the cover 15 has been closed.

4 shows the embodiment explained in FIG. 3 in the basic structure on a larger scale and in more detail. Matching components are provided with matching reference symbols. 5a, 5b, 6a and 6b then show the movement sequence of the device 23 up to the emptying position for a received waste container 24. FIG. 6b then shows the driving position.

Each pivot arm of the pair of pivot arms 25 is assigned a pivotable additional lever 36 in the region of the pivot bearing 26. The additional lever 36 is connected to the free end 30 of the associated swivel arm via a first swivel drive 37 in the form of a hydraulic cylinder. The additional lever 36 is also connected via a second swivel drive 38, which is also designed in the form of a hydraulic cylinder, to the vehicle, preferably to the support 39 for the swivel bearing 26, which structure is to be explained in more detail below. The hydraulic cylinders are only dotted by their lines of action. If the first swivel drive 37 is now acted upon, the swivel arm pair 25 swivels up the illustration shown in FIG. 5a. If the second swivel drive 38 is then acted upon, this swivels Pair of swivel arms 25 the emptying position shown in FIG. 5b. The second swivel drive 38 is in this case dimensioned such that the swivel arm pair 25 can be swiveled completely into the region of the intermediate walls 13 via the additional lever 36 beyond the emptying position, as is shown in FIG. 6b. It can be seen from the sequence of movements shown in the sequence of FIGS. 4, 5 and 6, the starting position in each case being indicated in the dash-dotted line in FIGS. 5a and 5b, that the pair of guide arms 31 with the one between the free ones Ends of the pair of guide arms 31 mounted pivotable receiving and tilting device 29 and the waste container 24 connected therewith can pivot between the pair of pivot arms 25. The fact that the arms of the pair of guide arms 31 are angled downward, as can be seen in FIG. 4, avoids shearing when swiveling up in the area accessible from the floor.

When using the hydraulic swivel motor explained above, the hydraulic cylinders 37, 38 with the corresponding stop elements are of course dispensed with. The hydraulic swivel motor is fastened directly on the carrier 39 so that it is axially aligned with the swivel bearing 26, so that its shaft acts directly on the swivel arm 25. Possibly. it is expedient to provide two hydraulic swivel motors, each of which drives one arm of the swivel arm pair 25.

4, 5a and 5b shows, the pair of guide arms 31 remains aligned with the horizontal through the chain 34 forming the guide means during the entire pivoting movement with respect to the horizontal, so that a waste container connected to it accordingly also remains vertical remains aligned. In order to be able to tilt the waste container 24, the receiving and tilting device is rotatably mounted between the free ends of the pair of guide arms 31

29 is connected with a tipping drive 40 in ^'the form of a hydraulic cylinder which is mounted with one end on the guide arm 31 and is articulated at its other end via a pair of transmission levers 41 to the receiving and tilting device 29. Only when the device has reached the emptying position shown in FIG. 6 is the waste container 24 pivoted into the illustrated tilting position via the tilting drive 40, the lid also being opened via corresponding drivers.

4 also schematically shows the attachment of the carrier 39 to the vehicle. In the exemplary embodiment shown, this is carried out by means of a three-point support on the chassis, a crossbar 42 being arranged directly behind the driver's cab 1 and being fixedly connected to the vehicle chassis via two fastening points lying next to one another. The third fastening point is provided at a distance behind the cross member 42, specifically via a centrally located support 43 which is articulatedly connected to the vehicle chassis. This hinge point lies, which cannot be represented here, in the central longitudinal axis of the vehicle chassis and can be formed both by a uniaxial joint and by a ball joint. This makes it possible for the vehicle chassis to twist about its longitudinal axis without constraints occurring between the fastening of the cross member 42 on the one hand and the articulation point 43 on the other hand.

The carrier 39 is only shown schematically in FIG. 4. In the practical embodiment, however, the carrier is designed as a box construction, with both the hopper 10 and partial areas of the side walls 13 also being designed as load-bearing elements, so that there is a relatively low weight with high rigidity. In Fig. 4, the front side wall is removed for reasons of simplicity, so that the arrangement of the parts lying between the side walls 13 is visible. Fig. 4 also reveals that the carrier 39 designed in this way also at the same time for fastening the press cylinder 8 and can be used to guide the ram 9. At least two locking pins 44 are preferably arranged next to one another on the carrier 39 below the extension 11 of the discharge opening of the hopper 10, said locking pins engaging in corresponding recesses in the collecting container to be connected and thus the collecting container 2 in connection with the hook-shaped ones not shown here Locking locking elements practically rigid, so that at least in the area in which the extension 11 projects into the collecting container 2, relative movements between the extension 11 on the one hand and the collecting container 2 on the other hand are largely excluded.

7 shows a simplified form of the device 23. This consists here only of a pair of swivel arms 25, between the free ends of which the receiving and tilting device 29 is rotatably mounted. The arrangement is such that a guide means, for example a chain guide 32, 33, 34, as described with reference to FIG. 3, is arranged, which ensures that the received waste container 24, as in the intermediate position 25 "' Only the pick-up process shown in the lowest position and the emptying process shown in the top position are then accomplished via a tilt drive arranged between the pair of swivel arms 25 and the pick-up and tilting device 7 shows that the clearance profile specified by the collecting container 2 is not significantly exceeded during the emptying process.

8 shows a modification of the embodiment according to FIG. Fig. 7 shown. Here, the pair of swivel arms 25 is provided with telescopically guided extensions 45, to which the receiving and tilting device 29 is fastened, as described above. Here too, guide means are provided which ensure that during the swiveling process remains aligned vertically in the emptying position of the waste container 24. These will be described in more detail with reference to FIG. 16.

A further embodiment is shown in FIG. 9, in which the pair of swivel arms 25 is angled downward in relation to the receiving position. The free ends of the pair of swivel arms 25 are then again provided with a pair of guide arms 31, on the free ends of which the receiving and tilting device 29 is in turn attached. The pivoting movement takes place in such a way that the pair of guide arms 31 is first pivoted up into the intermediate position shown, so that the total pivoting radius between the axis of rotation of the receiving and tilting device 29 on the one hand and the pivot bearing 26 on the other hand is correspondingly shortened. Thereafter, the pair of swivel arms 25 is pivoted into the emptying position, again the waste container 24 remains vertically aligned until the pair of swivel arms has reached the emptying position. Only then is the tilt drive actuated so that the waste container 24 is pivoted into the emptying position shown. The free height required for this embodiment is somewhat larger than that for the embodiment according to FIG. Fig. 4 required height, since here the pair of guide arms is pivoted away from the vehicle before the pair of pivot arms is pivoted about the pivot bearing 26. In contrast, pivots according to the embodiment. Fig. 4, the pair of guide arms directed against the vehicle between the pair of swivel arms 25 therethrough.

10 a) schematically shows a top view of the front area of the vehicle described with reference to FIG. 3. It can be seen here that the pair of guide arms 31, together with the receiving and tilting device 29, is arranged between the pair of swivel arms 25 and can swivel between the two swivel arms 25 during the swivel process. The top view in FIG. 10 a) shows the position of the swivel arm pair 25 in the receiving position near the ground. The rubble funnel 10 and the collecting container 2 are indicated schematically.

A further modification of the system described with reference to FIG. 3 will now be explained with reference to FIG. 10. For this purpose, the pivot bearing 26 of the pair of pivot arms 25 is connected to the carrier 27 via a pivot bearing 35, which in turn is connected to the carrier 27 so as to be displaceable in the longitudinal direction of the vehicle.

While Fig. 10 a) shows the position of the pair of swivel arms 25 with its swivel bearing 26 with respect to the vehicle, as is also the case with a rigid design according to Fig. 3, Fig. 10 b) shows schematically the above-described possibility that with the Pivot bearing 35 connected pivot bearing 26 to be moved forward in the vehicle longitudinal direction. To simplify the illustration, the connection of the pivot bearing 26 to the pivot bearing 35 is not shown. This makes it possible to arrange the pivot bearing 26 as deeply as possible in the front area above the driver's cab 1, since the entire arrangement on the right (FIG. 10 c)) or left side of the vehicle (FIG d)) can be pivoted. This also gives you the option of holding waste bins on the side of the road. In this case, after receiving a container standing on the side, the arrangement is pivoted back into the front area, moved back into the original position shown in FIG. 10 a), and then the waste container is emptied into the hopper over the driver's cab.

A further modification can also be derived from the illustration and description of FIG. 10. If the rotary bearing 35 is now not only in the longitudinal direction of the vehicle but also transversely to it, by a corresponding configuration of the carrier 27

Vehicle longitudinal direction slidably connected to the carrier 27, then it can be readily seen that one of FIG. 10 b corresponding advanced positioning of the pivot bearing 26 with the pair of pivot arms 25 can also be achieved for one of the two lateral positions corresponding to FIG. 10 c) or FIG. 10 d). Since the pivot bearing can be displaced transversely from the central position both to the right and to the left side of the vehicle, this modification gives the possibility of swiveling waste containers on one side of the vehicle across the cab and transversely to the longitudinal axis of the vehicle and the received waste - Empty container into a collecting container arranged on a second vehicle, for example a trailer that stands next to the receiving vehicle. With the help of the transverse displaceability of the pivot bearing 35, it is possible to bridge the necessary changes in distance.

11 shows the support of the collecting container 2 in the region of the rear end of the vehicle chassis 46 in a view against the rear of the vehicle. For this purpose, a crossbar 47 is provided, which serves to support and lock the collecting container 2, but also to guide it during the pick-up and drop-down process, which will be described in more detail below. The crossbeam 47 is provided with a pivot bearing 48 so that it is pivotably mounted about a pivot axis running in the longitudinal direction of the vehicle. Preferably, the pivot axis defined by the pivot bearing 48 is aligned with the hinge axis of the support point 43 of the carrier 39. This has the effect that the vehicle chassis 46 can twist in relation to the "rigid structure" formed from the carrier 39 and the collecting container 2 firmly connected to it . The only rigid connection between this "rigid structure" is in this case formed by the crossbar 42 on the carrier 39 which is fixedly connected to the vehicle chassis 46.

At least one positioning spring element 49 is provided between the crossbar 47 and the vehicle chassis 46 is only shown schematically here. The positioning spring element has the effect that, in the unloaded state, the crossbar 47 remains aligned parallel to the plane formed by the vehicle chassis 46. The positioning spring elements 49 are designed to be relatively soft, so that the cross member 47 and the vehicle chassis 46 can twist without any significant force.

On the crossbar 47, two guide rollers 50 are provided, which are rotatably mounted on the crossbar about vertical axes and which guide the collecting container via corresponding longitudinal beams on the collecting container 2 when picking up and setting down in the longitudinal direction. Furthermore, at the outer ends of the crossbeam 47, so-called bell rollers 52, each rotatably mounted about a horizontal axis, are provided, on which the collecting container 2 is supported after being picked up by the vehicle, so that the rear end of the collecting container 2 can roll on the bell rollers 52 when the container 2 over the

Carriage 18 is moved into the locking position, as described with reference to FIG. 2.

Also connected to the crossbar 47 are two locking hooks 53 directed towards the rear, which engage in corresponding recesses 54 on the collecting container 2, so that the rear end of the container is also positively locked with the crossbar 47 when the front end is locked with the locking pin 44 is securely locked to the carrier 39 by means of the locking hooks, which are not shown here.

The recording process is described in more detail with reference to FIGS. 12, 13, 14 and 15. To accommodate a collecting container 2 provided with pivotable legs 55, a vehicle designed for so-called interchangeable platforms is used, which can be lowered overall via hydraulic or pneumatic systems. The vehicle drives backwards 13 underneath the collecting container 2, as shown in FIG. 13, until its end wall comes to rest against a corresponding stop on the carriage 18 which has moved completely to the rear. Then, as can be seen from Fig. 14, the vehicle is raised to its normal position, so that the collecting container 2 is connected at the front end with corresponding pins 3 on the carriage 18, the driver 21 on the functional device 19 at the same time in the lock door on the collecting container 2 intervene. At the same time, the rear end of the collecting container 2 is supported on the bell rollers 52. After the closure door has been opened by the functional device 19, the collecting container 2 is also moved forward into its final position on the vehicle via the carriage 18 after the rear legs 55 have also been pivoted upward, as can be seen from FIG. 15. In this case, the extension 11 is inserted into the interior of the container, as shown and described in FIG. 3. At the same time, the locking with the locking pin 44 shown in FIG. 4 on the carrier 39 and the locking via the locking hook 53 at the rear end of the vehicle. In the exemplary embodiment shown, the carriage 18 is displaced via a piston-cylinder unit 57 fastened horizontally to the vehicle.

15 shows the vehicle which is ready for driving and ready for use, the device 23 for receiving and emptying waste containers being indicated only by the pivot bearing 26 for the sake of simplicity.

The description of the workflow with reference to FIGS. 4, 5 and 6 reveals the many possible uses. With appropriate design of the receiving and tilting device 29, waste containers 24 of various designs and sizes can be accommodated. It is also possible to hang several small waste containers next to one another on the receiving device and then empty them at the same time. The vehicle also allows use in the so-called

Bag removal. A large-volume receptacle is then attached to the receptacle here, into which the bags are then dropped. Short distances can also be covered with the pair of swivel arms removed, as the driver's view is not blocked. In the same way, it is also possible to collect bundled waste paper, especially newspapers. Even small waste or ash pails can then be emptied by hand into the receptacle, which is only emptied into the collecting container 2 when it is largely filled.

A vehicle designed in this way has the further advantage that the collecting container 2 is a bare steel construction and that no drives are arranged on the collecting container 2 itself. Therefore, there are no connection means for an energy supply. All actuation means, including their associated energy supply, are connected to the vehicle. This reduces the costs and the susceptibility to repairs for the collecting container and also allows the handling on the landfill, in particular the dumping, to be carried out with a special landfill vehicle. The collection containers can thus be parked without supervision.

The basic structure of the vehicle shown in FIG. 16 corresponds to the vehicles described above. For receiving and emptying a waste container 24, a swivel device 25 in the form of a swivel arm pair is now provided on the vehicle, the swivel arms of which are arranged parallel to one another and at a distance from one another which corresponds approximately to the width of the driver's cab 1. The pair of swivel arms 25 is arranged with a swivel bearing 26 in the front area above the driver's cab 1 on a support 27, a swivel drive (not shown in more detail) being provided which is designed such that the swivel arm pair is at an angle of approximately 180 degrees from the lower opening shown. take position can be pivoted into the illustrated upper emptying position. The swivel drive can in this case be formed by one or more coupled hydraulic piston-cylinder units, the required swivel angle being able to be achieved via corresponding lever arrangements, or also by a hydraulic swivel motor.

From the free end of the pair of swivel arms, a receiving and tilting device 9 for the waste container 24 is rotatably mounted about a horizontal axis. In order to be able to keep the waste container 24 aligned vertically during the entire swivel path of the swivel arm pair 25, a drive means in the form of an oil motor or a hydraulic swivel motor 59 is arranged on the swivel arm pair 25 in the illustrated embodiment, which is dimensioned via pipes with a correspondingly dimensioned Pump unit 60 is connected, which is arranged in the region of the pivot bearing 6. This is practically an identical unit, only with the difference that the drive takes place via the rotor shaft, so that this oil motor works as a pump. When the arm 25 pivots, the oil motor 59 is - as can be seen from the drawing - driven in synchronism with the pivotal movement of the pair of pivot arms 25. Synchronous running here means that the receiving and tilting device 29 is rotated at the same angular velocity as the pivoting device but in the opposite direction to the latter. Only when the upper emptying position of the swivel device has been reached, is the oil motor 59 pressurized by a corresponding switchover to another pump unit, so that the initially still vertically oriented receptacle is then swiveled into the emptying position shown. Finally, the waste container 24 is pivoted back into the vertical orientation and the pair of pivot arms is pivoted back into the receiving position. While in the embodiment shown in FIG. 16 the swivel bearing for the swivel device 25, ie in the case of the embodiment, a swivel arm pair is fastened in the upper front area of the cab, FIG. 17 shows a side view of an embodiment for a swivel arm pair in which the swivel mount 26 'is fixed directly to the vehicle chassis in an area located behind the driver's cab. The swivel arms 25 are designed in the shape of a bow and follow approximately the side contour of the driver's cab, so that free access to the driver's cab is ensured in the receiving position for waste containers. In this exemplary embodiment, a hydraulic piston-cylinder unit 61 is provided on each of the two swivel arms 25 as drive means for the receiving and tilting device 29, which is provided with a transmission linkage 62 with the receiving and tilting device 29 in FIG Way is connected.

A correspondingly dimensioned hydraulic cylinder 63 is arranged on the vehicle and is connected to the swivel arm 25 in the region of the swivel bearing, for example via a corresponding extension arm 64, so that the swivel movement of the swivel arm 25 can be converted directly into a piston movement. The double-acting hydraulic cylinder 63, which serves as a pump unit, is connected via corresponding pipes for inlet and outlet to the likewise double-acting hydraulic cylinder 61, so that each pivoting movement of the pair of pivoting arms 25 immediately results in a synchronized pivoting movement of the receiving and Tilting device 29 is implemented, i. H. this is pivoted at the same swivel speed but in the opposite swivel direction relative to the swivel arm pair 25, so that the waste container 24 remains essentially vertically aligned during the swivel path.

When the end position is reached, a corresponding reversing device can be used to change the pressure oil. Supply can be switched so that the cylinder

61 is pressurized with pressure oil so that the waste container 24 is pivoted against the filling opening and can thus be emptied.

18 schematically shows an embodiment of a locking plate 67 with which a closure, preferably an additional closure, is possible for the filling opening 6. For this purpose, a channel-like protective cover 66 is provided in the interior of the collecting container 2, which protrudes into the interior in the extension of the filling opening 6. In the region of its rear end, the locking plate 67 is preferably pivotably pivoted downward from above. The locking plate 67 is provided with actuating and / or closing means 68 which can be actuated from the outside of the container, for example via the functional device 19.

After, as described with reference to FIGS. 12 to 15, the collection container 2 has been picked up by the vehicle (FIG. 14), the locking plate 67 is also pivoted up when the closure door is opened, as shown in FIG. 18. As soon as the collecting container 2 is filled, a lock is released via the functional device 19 when the press ram 9 is withdrawn, so that the locking plate 67 folds downward. With the help of the ram 9, the locking plate 67 is then pressed into its end position. Residual amounts of waste are pressed out of the channel-like protective cover 66 into the collecting container. After locking the locking plate, the press ram 9 is then withdrawn so that the collecting container can be moved back without any residual amounts of waste falling out before the door 7 is closed; this is shown in phantom in FIG. 18. The locking plate 67 can also be divided into two parts and can be designed to be pivotable about a vertical axis from the side walls of the protective cover 66 into the opening cross section. If the locking plate is designed accordingly, in particular if the seal is sufficient, the arrangement of the locking plate may also be appropriate sufficient to close the filling opening, so that the arrangement of the closing door 7 described in FIG. 2 on the collecting container can be dispensed with.

It is expedient if the protective cover 66 is provided, at least with the final length of its bottom surface, with a slight inclination falling into the interior of the collecting container. The free space 69 under the protective cover can serve as a collecting space for leachate. If the front end wall 5 is simultaneously designed as an emptying flap for the collecting container, no residues can accumulate in this area.

The embodiments of the vertical guide for the waste container 24 according to the claims 8, 9 and 10 are not limited to vehicles which are equipped with the arrangement of the swivel arm pair according to the invention, but can in principle be used in all so-called front loaders with swivel arms for movement of containers to be emptied, in which the containers are emptied over the cab into a collecting container behind the cab by tipping.

The embodiments according to the invention of coupling the discharge opening of the press to the collecting container to be filled are not limited to a vehicle of the type according to the invention, but can be used for all vehicles which are provided with a refuse compacting device which is assigned a collecting container which can be detached from the vehicle. These are the configurations according to claims 14 to 22.
