Description

TECHNICAL AREA

The invention relates to a refuse container with a hinged lid, which is equipped with a receiving device in the upper area of the front wall of the lid hinge opposite the lid hinge for engaging a gripping device of a lifting and tilting device. The invention also relates to this gripping device on a lifting and tilting device for emptying such a refuse container.

STATE OF THE ART

From DE-Gbm 85 19 096 a waste container of the type mentioned is known, which has a single downwardly open receiving pocket on its outside facing the lifting and tipping device. The side walls of this receiving pocket run towards each other in a V-shape and form an acute angle of less than 90 degrees with the container wall. A correspondingly designed claw of a lifting and tilting device engages in this receiving pocket such that the container can be held by the claw in a tilt-proof manner in any direction. Since the receiving bag has to carry the entire load of the filled garbage container during the stroke-tilting movement and is also still subjected to shaking movements in the upper emptying position of the garbage container, the thin-walled receiving bag has in many cases proven to be not stable enough. If the storage bag is damaged, however, practically the entire plastic waste container can no longer be used.

To damage the pocket of such Exclude garbage container, it is known from DE-PS 37 03 034 to form the outer receiving pocket wall running parallel to the container wall in two layers, stiffened with each other by struts. In practice, it has been found that although the receiving pockets can withstand the rough operation and the heavy load acting on a waste container, damage to the container body itself now occurs; cases have become known where the container wall is torn open transversely below the receiving pocket.

PRESENTATION OF THE INVENTION

Based on this prior art, the invention has for its object to provide a garbage container of the type mentioned and a gripping device adapted to this garbage container of a lifting and tipping device, with which a correct and central pick-up of a garbage container on this lifting and tilting device is possible, namely in a way that is as gentle as possible on the container.

This invention is given in the aforementioned garbage container by the features of claim 1 and for the gripping device adapted to this garbage container by the features of claim 13.

The invention is therefore based on the knowledge that the almost articulated receptacle of the container by the two appropriately adapted claws during movement of the container in the plane perpendicular to the pivot axes of the lifting and tilting device does not cause any constraining forces in the receiving pockets, but rather that Container on the spherical surface of the receiving claws - within the specified limits - is freely pivotable. The container thus only rests on the at least two receiving claws during the lifting-tilting movement from above, and is not held clamped by the latter. The only vertical support of the container from a static point of view on the claws is sufficient, since the lower area of the container - in the well-known way - bears against the lifting and tipping device.

Due to the V-shaped spreading of the two receiving pockets, a container which is also laterally displaced on the lifting and tilting device is automatically centered when the receiving claws are raised, corresponding to the maximum spreading of these pockets.

In itself, the at least two receiving claws and the receiving pockets correspondingly present on the container can be aligned with one another as desired. Optimal stability for the container is achieved, however, with two receiving pockets arranged at the same distance from the upper edge of the container.

It has proven to be advantageous to arrange a transverse rib projecting from the container wall like a wall between the two receiving pockets. This cross rib can then be used simultaneously with the support wall supporting the container in its upper emptying position. By means of suitable contact bodies which are supported from above on the transverse rib from the direction of the container opening, the container is prevented from slipping into the emptying opening of a refuse collection vehicle.

Because the at least two receiving pockets are always present in the same way on the front wall of the container, containers of different sizes can also be accommodated by the same lifting and tilting device.

Now there are not only containers of different sizes on the market, but also containers with a fixed or adjustable partition. In order to ensure that the garbage contents pre-sorted into two components can also be appropriately emptied separately in a bed provided on a garbage truck, even with such garbage containers provided with an intermediate wall, the intermediate container wall with the partition that is also present in a bed.

In order to ensure this, the container with its intermediate wall must be precisely aligned with the lifting and tilting device according to DE-OS 36 29 291 with its intermediate wall on the lifting and tilting device. This means that the operating personnel position the container precisely on the lifting and tipping device, which entails a not inconsiderable additional expenditure of time for the operating personnel.

In order to reduce this additional expenditure of time as far as possible, a bed has become known in which a refuse container equipped with a variable intermediate wall, regardless of the position of its intermediate wall, can always be attached to the lifting and tilting device in the same orientation. In order to ensure the mutual alignment of the intermediate bed wall with the intermediate container wall, the intermediate bed wall is designed to be laterally adjustable. The necessary adjustment of the bulkhead partition is effected by the operating personnel by means of corresponding actuators on the lifting and tilting device. An automatic control device ensures that if the bed and container wall are not aligned with one another, the container cannot be emptied into the bed. With this lifting and tipping device, a complicated alignment of the container on the lifting and tipping device is avoided, but it is necessary for the operating personnel to make a decision which, depending on the respective position of the intermediate wall of the container, must actuate corresponding actuators on the lifting and tipping device.

In order to make the lifting and tilting device work fully automatically even in such cases, a garbage container is advantageously equipped on the outside with a position detection device which indicates the position of its partition. This positioning detection device advantageously consists of at least one Marking area which is designed such that it differs in color and / or shape and / or material property from the container wall surrounding it. This marking area corresponds to a device that recognizes it and is provided on the lifting and tilting device. It has been found to be advantageous for practical operation if the marking area is a body that can be detachably attached to the container, or if the marking area is provided on a body that in turn is detachably attached to the container. The body can be plugged, inserted or screwed to the container.

The number of marking areas should at least correspond to the number of different positions of the middle wall within a container. In addition, marking areas present on each outside of the container can serve to indicate that there is no partition in the container and that the container contents can then be emptied into one or the other fill opening.

These positioning detection devices are not only of crucial importance in the case of the above gripping device in the form of the two claws and containers adapted in connection with these claws, but can also be used in general with all containers. With their help, the corresponding intervention by operating personnel can be dispensed with. As a result, the time required for positioning a container on a lifting and tipping device and for starting the lifting and tipping device can be shortened even further compared to the prior art.

So that the gripping device on a lifting and tipping device for emptying garbage containers is optimally adapted to the above receiving pockets, the gripping device has at least two receiving claws which are approximately spherical in shape at their respective free ends and a receiving bar, each of the at least two receiving claws each having one correspondingly complementarily curved undercut receiving pocket cooperates in the upper region of a refuse container and, in addition, the receiving strip is designed with the container wall of the refuse container for supporting the lower region thereof.

For gentle support of the container, in particular in its upper emptying position, the gripping device advantageously has an elastically flexible holding device. This holding device can in particular be an elastically flexible body.

It has proven to be advantageous to arrange the body in such a way that it can be placed at least partially in the area between the two receiving pockets on the container wall having these receiving pockets. The body can, for example, be supported elastically on the transverse ribs present between the two receiving pockets, so that the container can be held in its upper emptying position in an elastically flexible manner. Due to the elastic flexibility, not only is the container itself treated gently, but also the noise generated during the current emptying of known fillings is noticeably reduced.

Further refinements and advantages of the invention can be found in the features which are also listed in the claims.

WAYS OF CARRYING OUT THE INVENTION

A garbage container 10 is equipped with a lid 12 which is fastened in a foldable manner in the region of the rear wall 14 of the garbage container 10.

The interior of the garbage container 10 is divided into a left chamber 18 and a right chamber 20 by an intermediate wall 16. This intermediate wall 16 is held in vertical groove-like guides 22, 24, 26, 28, 30, one of the grooves 22 to 30 on the rear wall 14 and a corresponding groove-like guide 22 to 30 on the opposite front wall 32. Depending on the position of the intermediate wall 16 in one of the grooves 22 to 30, the left chamber 18 and the right chamber 20 each have a different size.

On the outside of the front wall 32 there are left and right receiving pockets 34, 36. Each of the receiving pockets is formed, on the one hand, by the front wall 32 and, on the other hand, by V-shaped side walls 38, 40, which enclose an interior tapering on three sides. In cross-section, the side walls 38, 40 are arched, the side surfaces of the two side walls 38, 40 facing away from the front wall 32 being directed towards one another with a view of the front wall 32, so that the curvature represents an undercut, viewed from the outside.

Also in the upper area of the receiving pocket 34, 36, where the two side walls 38, 40 each converge these are arched from the outside, with a circular cross-sectional shape.

The right side wall 40 of the receiving pocket 34 in FIG. 1 and the left side wall 38 of the receiving pocket 36 are stiffened together by a transverse rib 44 running approximately parallel to the upper opening edge 42. This cross rib 44 is also integrally connected to the front wall 32.

In the upper region of the receiving pockets 34, 36, approximately in terms of height in the region of the common abutting region of the respective two side walls 38, 40 of each receiving pocket 34, there is a further transverse rib 46 on the front wall 32. In the central region of this transverse rib 46 there are five depressions 48, 50, 52, 54, 56. A button-like body 58 is inserted into the one recess 54 and is provided with a metallic surface in the present example. The indentations 48, 50, 52, 54, 56 are each aligned with the grooves 22, 24, 26, 28. In alignment with the groove 28, the button 58 is present in the depression 54, so that the position of the button 58 is due to the position of the button 58 Partition 16 inside the container 10 is visible from the outside even when the lid 12 is closed.

At the left and right outer ends of the transverse rib 46 there are further recesses 60 and 62, respectively, into which the button-like body 58 can also be inserted. The button-like body 58 is then inserted into one of these two depressions when there is no intermediate wall 16. The button-like body 58 in the recess 60 makes it clear that there is only a single chamber inside, namely the chamber 20, while the position of the button 58 in the recess 62 shows that only the left chamber 18 and thus the one in this chamber belonging, correspondingly pre-sorted waste portion is present in the waste container 10.

In the area of the upper edge 42, the container 10 has a circumferential envelope edge 70. In the area of the front wall 32, this envelope edge is connected to the front wall 32 by stiffening ribs 72, so that the envelope edge 70 has a very stable and rigid construction in the area of the front wall 32.

1 shows a left and right claw 80, 82 of a lifting and tilting device 84 (FIGS. 2, 3). Each of these claws 80, 82 has a spherical body 85, 86 at its upper, free end. The curvature of these two balls 85, 86 is adapted to the inner curvature of the side walls 38, 40 of the two receiving pockets 34, 36. The mutual distance X of the two balls 85, 86 corresponds to the distance X of the two receiving pockets 34, 36 measured in the same direction.

A bar 87 is also provided on the lifting and tilting device 84, on which - corresponding to the number of depressions 48, 50, 52, 54, 56, 60, 62 on the transverse rib 46 - a corresponding number of sensors 88, 90, 92, 94 , 96, 98, 100 are present. The sensors are connected to the control of the lifting and tilting device and react to the presence of the button-like body 58. In the present example, the sensor 96 would respond to the presence of the button 58 and a corresponding electrical signal when the bar 86 approaches the transverse rib 46 generate, the use of which is explained in more detail below.

In the lower area of the lifting and tilting device there is also a stop bar 110 on which buffer bodies 112 are attached. With these buffer bodies 112, a gentle contact of the waste container 10 with the contact strip 110 and thus with the lifting and tilting device 84 is ensured.

The lifting and tilting device 84 is positioned on a bed 120 which is divided into a left and right shaft 124, 126 by an intermediate wall 122. The partition 122 can be adjusted so that its upper edge 130 is aligned with the upper edge 132 of the intermediate wall 16. This ensures that the contents of the left chamber 18 are emptied into the left shaft 124 and the contents of the right chamber 20 into the right shaft 126 and that no mixing of a pre-sorted waste in the waste container 10 can occur within the bed 120. The partition 122 is adjusted automatically in accordance with the electrical signal generated by the sensors - in the present example by the sensor 96.

The lifting and tilting device 84 has, in a manner known per se, two parallel swivel arms 134, to each of which two articulated arms 136 and two action levers 138 are articulated. The free ends of the two articulated arms 136 and the action lever 138 are also connected in an articulated manner by a lifting carriage 140 which has two stems.

The bar 87 equipped with the sensors 88 to 100 is fastened to the lifting and tilting device 84 - for example to the lifting truck 140 - in such a way that when the garbage claws 80, 82 pick up a garbage container, the sensors position the button-like body 58 as early as possible registering position.

As is clear from FIG. 3, the sensors are positioned in the region of the common axis of rotation 148 by the articulated arms 136 and the lifting truck 140 in such a way that they are in their "registration position" as soon as the spherical bodies 85, 86 are fully in the receiving pocket 34, 36 are retracted upwards.

The position of the sensors 88 to 100 approximately at the level of the spherical bodies 85, 86 fully immersed in the receiving pockets influences a relative rotational position of the container relative to the lifting truck - cf. Fig. 3 - the registrability of the sensors is not.

Is between the swivel arms 134 and the action levers 138 there is a cylinder arrangement 144 with which the action levers 138 can be pivoted relative to the pivoting arms 134 and thus the lifting truck 140 can also be pivoted as well.

A second cylinder arrangement 146, which is fastened to the bed 120, serves to pivot the swivel arms 134.

Two elastic bodies 150, 152 are present in the upper region of the swivel arms 134. Their position is such that they lay down on the front wall 32 in the upper emptying position of the waste container 10. In this case, the body 150 lies against the envelope edge 70, which is rigid due to the stiffening ribs 72, and the body 152 lies directly against the front wall 32 in the region between the receiving pockets 34, 36 and the transverse ribs 44, 46.

Due to their elastic flexibility, both bodies 150, 152 ensure that the garbage container 10 is not braked suddenly or jerkily, but rather elastically flexible in its emptying position. The resulting gentle treatment of waste containers not only has a beneficial effect on their lifespan, but also significantly reduces the background noise when emptying.

The upper body 150 is preferably used for the elastic braking of the waste container in its emptying position, while the lower body 152 preferably prevents the container with its opening obliquely downward in its emptying position from slipping into the bed 120 by its abutment on the transverse rib.
