Abstract

Un camion de collecte d'ordures comprend un conteneur amovible de collecte (1) et un mécanisme de chargement (7) pouvant être séparé de celui-ci par basculement latéral. Le mécanisme de chargement (7) comprend un espace de réception des ordures (6) et une pelle de chargement (11) se déplaçant à travers cet espace jusqu'à l'ouverture (2) de remplissage du conteneur. La lame (23) de la pelle de chargement (11) peut être enlevée du mécanisme de chargement (7) afin de fermer l'ouverture (2) de remplissage du conteneur et peut être assujettie au conteneur de collecte (1). Le camion de collecte d'ordures peut se déplacer sur une courte distance avec le mécanisme de chargement déployé (7), ce qui permet de transférer le conteneur de collecte (1) sans problèmes sur un wagon de chemin de fer. Ce procédé de collecte d'ordures permet d'entreposer le conteneur de collecte plein (1) ou de le charger directement sur des wagons de chemin de fer, et de transporter les conteneurs, lorsqu'un nombre suffisant de conteneurs de collecte (1) ont été chargés, jusqu'à un dépôt de déchets ou à une usine d'incinération de déchets. On obtient ainsi un coefficient élevé d'utilisation des camions de collecte d'ordures, étant donné qu'ils sont uniquement utilisés pour collecter les ordures et non pour les transporter sur des longues distances, ce qui peut être effectué par des véhicules sensiblement plus économiques (chemin de fer, semi-remorques,...).A garbage collection truck comprises a removable collection container (1) and a loading mechanism (7) which can be separated from it by lateral tilting. The loading mechanism (7) comprises a refuse reception space (6) and a loading shovel (11) moving through this space up to the opening (2) for filling the container. The blade (23) of the loading shovel (11) can be removed from the loading mechanism (7) in order to close the opening (2) for filling the container and can be secured to the collection container (1). The garbage collection truck can travel a short distance with the loading mechanism deployed (7), which allows the container to be transferred (1) without problems to a railway wagon. This method of collecting rubbish makes it possible to store the full collection container (1) or to load it directly on railway wagons, and to transport the containers, when a sufficient number of collection containers (1) have been loaded to a waste depot or waste incineration plant. This results in a high coefficient of use of garbage collection trucks, since they are only used to collect garbage and not to transport it over long distances, which can be done by significantly more economical vehicles (railway, semi-trailers, ...).

Description

Mfiiig_.τnτnelfa-_rzeug with an interchangeable collection container _for processes for the removal of garbage and discharge device for emptying the collection container.

The invention relates to a refuse collection vehicle according to the preamble of patent claim 1, a method for the removal of waste from the preamble of patent claim 13 and an ejection device for emptying the collection container according to the preamble of patent claim 16.

A MÜU collecting vehicle is known from DE-OS 25 49 243. The known MüU collecting vehicle has a loading mechanism that can be connected and disconnected to an exchangeable collecting container. The collecting container is closed on the loading plant side with a flap which also serves as a pressure and closing vane. The loading unit is coupled by lifting the rear axle of the refuse collection vehicle, the loading unit standing on fold-out supports. The problem-free coupling and uncoupling of the loading plant, in particular its power supply lines, is complex and therefore time-consuming.

Another MüUsammel¬ vehicle is known from DE-OS 28 16 959. This MüU collecting vehicle also has an exchangeable collecting container and a loading mechanism which can be pivoted away from the container filling opening. The collecting container is closed at the rear by a flap which can be opened for emptying. To prevent the garbage collection vehicle from tipping over when the loading unit is swung out, support bearings are arranged below the swivel bearings.

This MüU collection vehicle does not allow easy and quick unloading and reloading of the collection container.

The object of the invention is to create a waste collection vehicle in which the replacement of the waste collection container can be carried out simply and quickly.

The solution to the problem is the subject of patent claim 1 with regard to the refuse collection vehicle, the subject matter of patent claim 13 with regard to the method for the removal of refuse and the subject matter of patent claim 16 with regard to the ejection device for emptying the collecting container. Preferred embodiments of the refuse collection vehicle are in patent claims 2 to 12 and the method in claims 14 and 15.

The MüU collecting vehicle described in claim 7 with an approximately horizontally displaceable and pivotable about a vertical pivot axis loading mechanism can also with a loading element other than the loading shovel described in claim 1 can be used. Instead of the loading shovel z. B. a loading screw can be used. The loading mechanism, which can be pivoted approximately horizontally and about a vertical axis, allows a loading ramp for loading the collection container onto z. B. to approach a railroad car at almost any angle and then to give away the loader to the side where most of the space is still available, ie it is also possible to load garbage containers with limited space and limited maneuvering space for the MüU¬ collection vehicle . The MüU collecting vehicle can also drive with the loading mechanism swung out, since this can be supported on a wheel that can be extended or folded onto the surface of the guideway. This results in even better maneuvering options for the MüU collecting vehicle.

An example of the refuse collection vehicle according to the invention is explained in more detail below with reference to the drawings. Show it:

8 is a view from below of the variant shown in FIG. 7, the displacement device, the pivot axis and the loading mechanism being shown in the pivoted position and in the only displaced position being drawn out. The MÜU collecting vehicle shown in FIG. 1 has an exchangeable collecting container 1 with a rear-side container filling opening 2, which is fastened on the chassis 3 of the MÜU collecting vehicle and locked with a releasable blocking member. Arranged on the rear side of the collecting container 1 is a loading mechanism 7 which can be displaced with respect to the longitudinal axis of the refuse collection vehicle by means of a displacement device 4 and can be pivoted about a vertical pivot axis 5 and which has a rear opening in its lower region for the garbage receiving space 6 of the loading mechanism 7. The MüU collecting vehicle with the loading mechanism 7 swung out to the side is shown in FIG. The collecting container 1 rests on slide rails 8a and 8b of the chassis 3 and is secured thereon with the above-mentioned blocking element to prevent it from slipping down while driving and being loaded. On the bow side, as indicated by dashed lines in FIG. 1, an ejection sign 10 which can be moved to the rear of the collecting container 1 is arranged inside the collecting container 1. An opening 14 is arranged in the lower third of the front end wall 12, which, as described below, serves to insert a plunger 45 of an ejection device 46. Below the opening 14 there is a holding element 16 for a holding device 18 of the ejection device 46 in order to be able to block the ejection device 46 in its position relative to the collecting container 1 when the garbage collected therein is ejected as described below.

The loading unit 7 has a loading shovel 11 which can be pivoted via two hydraulic piston-cylinder units 9a and 9b and has two articulated arms 13a and 13b, the foot point of the arm 13a on the loading unit 7 at the level of the lower edge of the collecting container 1 is stored. Instead of a loading shovel 11, two loading displays arranged on the side of the loading unit 7 can also be be present. The free ends of the arms 13b are attached to a plate-shaped blade carrier 15 which carries a loading bucket 17. The shovel blade supports 15 are smaller by a tolerance than the container fill opening 2. The loading shovel 11 is shown in side view in FIG. 1, its rear view when the loading mechanism 7 is pivoted to the side, is not shown in FIG. 2 in order not to overload the figure.

Approximately in the center line of the blade carrier 15 on its side opposite the fastening at the end of the arm 13, as shown in FIG. 3, two hydraulic piston-cylinder units 17a and 17b which can be used for pushing and pulling purposes are aligned in their longitudinal axis. The piston-cylinder units 17a and 17b are firmly connected to the hydraulic system of the refuse collection vehicle, not shown. Each piston rod of each piston-cylinder unit 17a or 17b has a U-shaped gripper 19a or 19b at its end. Parallel to the longitudinal axis of the piston cylinder units 17a and 17b, approximately at a distance of a quarter of the airfoil carrier width from their longitudinal edge, a bearing bushing 21a and 21b is mounted on the airfoil carrier 15 on the same side as the piston cylinder units 17a and 17b .

A loading blade 23 is removably attached to the airfoil carrier 15. A locking device on the rear of the loading display 23 serves for fastening, as shown in FIG. The top view in FIG. 4 shows the side of the airfoil 23 which is placed on the side of the airfoil carrier 15 shown in FIG. The locking device has four locking bolts 25a to 25d which can be displaced in the longitudinal direction as locking members, each of which is approximately in the stood one sixth of the airfoil width from the respective airfoil broad side of the bearing bushing 27a to 27d as well as a further bearing bushing 28a to 28d each arranged on the broad side of the airfoil 23 are displaceable. In each case two locking bolts 25a and 25c and 25b and 25d lying on a broad side are connected to one another by a cross connection 29a and 29b, respectively. The locking bolts 25a and 25b and 25c and 25d are aligned with one another. The height of the bearing bushes 21a and 21b and that of the bearing bushings 27a to 27d is the same, so that pressure is also exerted by the airfoil carrier 15 via these bearing bushings 21a, 21b, 27a to 27d when the waste is pushed in from the refuse receptacle space 6 can be transferred into the container filling opening 2 on the airfoil 23. The height of the grippers 19a and 19b is smaller by a tolerance than the height of the bearing bushes 21a, 21b, 27a to 27d so that the grippers 19a and 19b can be moved between the airfoil carrier 15 and the airfoil 23.

The cross connections 29a and 29b are so wide and so deep that the interior of the U-shaped grippers 19a and 19b can reach over them. The length of the transverse connections 29a and 29b and the position of the bearing bushes 27a to 27d and 28a to 28d are selected such that the ends of the locking bolts 25a to 25d pointing towards the center when the blade leaf 23 is pressed onto the blade carrier 15 into the bearing bushes 21a and 21b are insertable and displaceable in them.

The edge of the square container filling opening 2 has on its broad sides two holding bushes 31a to 31d designed to match the bearing bushes 28a to 28d and the locking bolts 25a to 25d. The container fill opening 2 is in a rear end wall 30 arranged, which is pivotally mounted on a pivot axis 32 on the roof 34 of the collecting container 1 perpendicular to the axis of the refuse collection vehicle. The end wall 30 is secured against flaps by a bolt 36 a, shown schematically in FIG. 1, at the rear lower end of the collecting container 1. The bolt head is secured to the collecting container with a screw spindle, not shown, which can be rotated with a ratchet, not shown.

The length of the locking bolts 25a to 25d is chosen so that the distance between the adjacent ends of the locking bolts 25a and 25b as well as 25c and 25d in the locked state apply by the locking bolts 25a to 25 engaging in the holding bushings 31a to 31d by a tolerance larger is as the length of the bearing bush 21a or 21b, un in the unlocked state, in which the locking bolts 25a to 25d are pulled out of the holding bushes 31a to 31d and that the airfoil 23 can be removed from the container filler opening 2, the neighboring ones Do not hit ends of locking bolts 25a and 25b, 25c and 25d.

As already mentioned above, the loading unit 7 is attached to the vertical pivot axis 5 such that it can be moved laterally. The displacement takes place with a displacement device 4 attached to the rear of the chassis 3 by means of a piston-cylinder unit 33 indicated in FIG. 2. The loading mechanism 7 is pivoted by approximately 180 ° after the displacement by a few ten centimeters, preferably by twenty centimeters, about the pivot axis 5 with the help of a hydraulic motor 39 acting on it. The lateral displacement of the loading unit 7 relative to the collecting container 1 creates a free space 41 between the loading unit 7 and the loading unit 7, which allows the driver of the refuse collection vehicle to reverse the refuse as mentioned below. Collection vehicle allowed to look back through the intermediate space 41 with the loading work 7 pivoted to the side. The hydraulic motor 39 holds the loading unit 7 in its position in the swung-out state even when moving.

Approximately in the middle of the right-hand side of the loading plant there is a wheel 37 which can be extended against the travel surface 35 and rotates completely about its vertical axis and which supports the weight of the pivoted loading plant 7 on the travel surface 35.

To collect garbage, the loading unit 7 is firmly locked with the collecting container 1. Among garbage a. pressable materials, rubbish, cardboard, waste paper, wood chips, compostable green waste, etc. understood. The airfoil 23 is fastened on the airfoil carrier 15 in such a way that the locking bolts 25a and 25b and 25c and 25d lie with their one ends in the bearing bushing 21a and 21b. The gripper 19a or 19b sits on the cross connection 19a or 19b. The piston-cylinder units 17a and 17b are withdrawn. The airfoil 23 closes the container filling opening 2. If the garbage receptacle 6 is filled with garbage, the airfoil 23 with the arms 13a and 13b of the loading shovel 11 is moved over the upper part of the loading unit 7 into the outer lower part of the loading unit 7, in which the Garbage receiving space 6 is located, moves, detects the garbage here and pushes it through the container filling opening 2.

If the collecting container 1 is completely filled, the MÜU collecting vehicle travels to a train station as the collecting container loading location, as shown in FIG. 5a. Here the airfoil 23 is pressed into the container filling opening 2, the cob cylinder units 17a and 17b press their respective pistons with the gripper 19a or 19b to the outside. As a result, the locking bolts 25a to 25d are pushed outwards into the holding bushes 31a to 3 of the container filling opening 2 and are pushed out of the bearing bushes 21a and 21b. The airfoil 2 is now locked in the container fill opening 2 and unlocked from the airfoil carrier 15. To clarify this process, the loading unit 7 is shown once locked with the airfoil carrier 15 in FIG. 1 (extended illustration) and once the container filler opening 2 closed with the airfoil 23 (dashed line illustration of the airfoil 23).

Then the loading unit 7 is unlocked and pushed with the shifting device 4 by twenty centimeters to the side and then pivoted with the hydraulic motor 39 about the pivot axis 5 by 180 ° until the loading unit is next to the collecting container 1, separated from it by the free space 4 . With the loading mechanism 7 pivoted out, as shown schematically in FIGS. 5b and 5c, the truck collecting vehicle moves backwards to a railway carriage 43 with the rotating frame 4 already pivoted out, the collecting container 1 is on the slide rails 8 and 8b by the truck collecting truck on the rotating frame 44 of the railway carriage 43 pushed. Is the Müllsammelcon tainer 1 completely on the rotating frame 44, this is pivoted back onto the railway carriage 43 (Figure 5d). This loading system is called ACTS (roll-off container transport system) by the Swiss Federal Railways.

Depending on the distance of a depot for empty collection containers from the loading location, the MÜU collection vehicle travels to the sem with the loader 7 unfolded or retracted. Here, an empty collecting container 1, the con tainer filling opening 2 is closed with a corresponding blade 23, charged. The airfoil Carrier 15 is pressed against the airfoil 23, the grippers 19a and 19b engaging over the cross connections 29a and 29b. The piston-cylinder units 17a and 17b pull the grippers 19a and 19b towards the center of the airfoil carrier 15, as a result of which the locking bolts 25a to 25d are inserted into the bearing bushes 21a and 21b of the airfoil carrier 15. The airfoil 23 is now connected to the airfoil carrier 15. The MüUsammel¬ vehicle is ready for collecting garbage again.

If several railway carriages 43 are loaded with collecting containers 1, they are driven to a landfill, waste incineration plant, etc. Here the bolts 36, which lock the rear end wall 30 with the collecting container side wall, are opened and one collecting container 1 after the other is pivoted out with the rotating frame 44. The discharge plate 10 located on the front end wall 12 is moved to the rear of the collecting container 1 with the above-mentioned discharge device 46.

The ejection device 46 shown in FIG. 6 has a movable frame 47 on one end face of which the holding device 18 already mentioned above and the piston 48a of a piston-cylinder unit 48 are arranged. To unload the collecting container 1, the ejection device 46 with the end face carrying the holding device 18 is moved against the front end wall 12 of the collecting container 1 pivoted out on the rail car 43 and its position to the collecting container 1 is blocked, in which the holding device 18 with the holding element 16 is connected in the front end wall 12. Subsequently, the piston 48a of the piston-cylinder unit 48 is pressed as a tappet through the opening 14 in the front end wall 12 against the ejection plate 10 and locked with it on a locking element 50 of the ejection plate 10. By the Moving the discharge plate 10, the waste is pushed against the rear end wall 30, the end wall 30 is thereby pivoted upward and the waste falls from the collecting container 1 into a collecting basin 49 (or a conveyor device, not shown) of the landfill or the waste incineration plant. If the ejection plate 10 has been pushed to the rear of the collecting container 1, the garbage is completely emptied from the collecting container 1, the ejection plate 10 is pulled back into its starting position, the collecting container 1 together with the rotating frame 44 is turned back and the The end wall 30 is locked again with the latch 36 on the side wall of the collecting container and the ejection device 46 is unlocked from the collecting container 1. If all the collecting containers 1 are emptied, they are transported from the landfill or the waste incineration plant back to the depot for empty collecting containers 1.

Instead of the locking bolts 25a to 25d, locking levers, not shown, which are screwed into slots, not shown, in the edge of the container filling opening or in the airfoil can also be used.

The advantage of the refuse collection vehicle according to the invention lies in the container filling opening, which can already be closed with the loading unit still connected to the collecting container, which enables the loading unit to be swiveled away quickly without waste falling out of the collecting container.

Furthermore, the MüUsammelfahr¬ vehicle can advantageously be moved a short distance with its loading mechanism pivoted away from the collecting container. This enables the collecting containers to be loaded correctly on railway wagons. The garbage collection process described here makes it possible to deposit the full collection containers in one place or to load them directly onto rail wagons, and then when enough collection containers are loaded, they can be transported to a landfill or waste incineration plant. In this way, a high level of utilization of the refuse collection vehicles is achieved, since they are only used for collecting refuse and not for long-distance transport of the refuse, which can also be carried out with significantly less expensive and also specially equipped vehicles (railroad, articulated lorry). Journeys of the refuse collection vehicle between its refuse collection tour and a waste incineration plant located away are completely eliminated. This results in a lower fuel consumption of the refuse collection vehicle, which results in a lower pollutant emission. The waste collection vehicle according to the invention represents an environmentally friendly disposal system.

The intermediate space 41 between the collecting container 1 and the loading unit 7 swiveled to the side facilitates the backward movement of the refuse collection vehicle and allows the vehicle driver to start the turning frame 44 in a targeted manner.

Instead of moving the loading unit 7 as in FIGS. 5a, 5b, 5c and 5d with the sliding device 4 shown in FIGS. 1 and 2 and pivoting about the vertical pivot axis 5, so that the loading unit 7 is placed to the right of the collecting container 1 7, a loading unit 52, which is designed analogously to the loading unit 7, can also be displaced horizontally with a shifting device 51 shown in FIGS. 7 and 8 from a collecting container 54, which is configured analogously to the collecting container 1, and arranged around a longitudinal axis 53 in the vehicle. nete pivot axis 55 are pivoted. The swivel axis 55 is offset from the rear end wall 57 of the collecting container 54 towards the front in the direction of the driver's cabin by more than the width of the loading unit 52. Analogous to the loading station 7, a wheel (not shown) which can be extended or folded out on the surface of the guideway is arranged on the loading station.

The loading unit 52 is first shifted backward, as shown in FIG. 8, so that it can be pivoted about the right or left corner of the collecting container 54 without bumping into it. Subsequently, it may then, depending on orhan- v ^'the space next to the collection container 54 in the position shown in broken lines A or B will be pivoted.
