Definitions

• the invention relates to a device for emptying containers provided with laterally projecting supporting elements, for example trunnions, for example waste containers into a collecting container, in which a pair of pivoting arms actuated by means of a tilting device is provided, which receive the container to be emptied between them and by means of at the free end of each swivel arm attached support devices, such as claws, swinging on the side support elements, whereby additionally a support and abutment device is provided to force a tilting movement of the container with the swivel movement of the pair of swivel arms, the interacting elements of which are attached to at least one front side wall region of the container pin or rod-shaped support and locking element and at least one in
• a device of the type described above in which in the interior of the pair of swivel arms a receptacle for a pin-shaped and rod-shaped support and locking element attached to the front side wall area of the container is designed as a double receptacle, with one upper receptacle and a lower receptacle and an intermediate spacing area.
• the pin or rod-shaped support and locking element attached to the container side wall must be correct be inserted into the spacing area between the upper receptacle and the lower receptacle so that the support devices attached to the free ends of the swivel arms can accommodate the laterally projecting support elements provided on the container.
• the Schwen arms are set at a precise altitude to accommodate a container to be emptied. This requirement is often difficult to meet, especially when particularly large and heavy containers are to be emptied, to which a collecting vehicle equipped with the emptying device must be driven backwards.
• the double receptacle for the supporting and locking element is disadvantageous if the laterally projecting supporting elements of the container to be emptied are more or less far outside the vertical planes running through the center of gravity of the filled container.
• Such a container with an eccentric center of gravity will only run into the known emptying device with its support and locking element from the distance area into the upper or lower receptacle, but will not change from one receptacle to the other in the manner desired in the known device. As a result, the interaction with the abutment is not completely reliable in such cases.
• the support and locking element included in the double receptacle is not able to leave the receptacle when the container is in the end tilting position, so that the dumping depth of the container to be emptied into the collecting container is limited.
• the receptacle has a support and abutment lever which is pivotally mounted on the swivel arm and can be seen with a control link in the form of a rod-shaped transmission element articulated with its one end on the support and abutment lever and its other end at a fixed point on the device frame, where b) the position of the fixed point on a plane corresponding to the middle swivel range of the swivel arms is shifted relative to the swivel axis of the swivel arms such that the support and abutment lever in the lower swivel range of the swivel arms assumes an initial inclination downward with respect to the respective swivel arm, in the middle swivel range the swivel arms swiveled to the respective swivel arm and in the upper swivel range of the swivel arms backwards from the respective swivel arm arm is swung away; and that c
• the support and locking element After transfer of the support and locking element to the end abutment, the support and locking element is released from the support and abutment lever in the device according to the invention, so that the pivoting range of the swivel arms is no longer limited by the receptacle for the support and locking element on the container , but a further pivoting of the swivel arms can be pivoted further into a deep tilting position of the container to be emptied with respect to the collecting container.
• the container to be emptied can be inserted into the opening of the collecting container with the lowest possible lifting height and with a securely defined position with respect to the swivel arms, and then when the actual tipping is started around a horizontal axis swiveling insert chute to be gripped at the opening edge.
• a significant improvement of the tipping-in process can also be achieved by an improved design of the lid opening device (if such is provided).
• the following, cooperating features are proposed as an advantageous addition and development of the invention within the scope of the invention: a) a driver designed in the form of an angle lever and with the apex of its angle lever arms is mounted on the free end region of each swivel arm; b) at the free end region of each swivel arm is also articulated a lid opener frame extending over the container lid, at the free end of which a lid opener rocker arm is pivotally attached under the lid, and c) control connecting elements engage on both angle lever arms of the drivers, each of which one of the Lid opener swing arm and the other is connected to a fixed point on the device frame.
• This improved lid opening device works with full operational safety even if the support and abutment lever allows a relatively large area for the pendulum movement of the container to be emptied with respect to the swivel arms. Furthermore, the lid opening device offers significant improvements with regard to the secure detection of the free lid edge by the pivotable mounting of the lid opener rocker on the lid opener frame. By equipping the lid opening device with the driver designed in the form of an angle lever, an additional lid closing frame can be operated in a particularly reliable manner via a resilient connection to the driver, in order to ensure that when emptying containers with a double hinged lid only one (hinged lid located below in the tilted position) ) is opened and the other hinged lid is held securely.
