Definitions

  • the invention relates to a lifting and tipping device for emptying containers into the pouring opening of a collecting container, in particular for emptying garbage containers into the collecting container of a refuse collection vehicle, in which a four-bar linkage with an upper and a lower handlebar is provided, which to form the four articulation points with one Receiving emptying container and during the emptying process until the emptied container is held, the lifting and tipping frame is connected to a rear articulated lever opposite this, a controlled drive device for generating the lifting and tilting movement inserted between the upper link of the four-bar linkage and the collecting container is provided .
  • an articulated quadrilateral supporting the lifting and tipping frame is attached to a pivoting arm pivotably mounted in the region of the pouring opening, the relative lifting movement of the lifting and tilting frame with respect to the pivoting arm being effected by a cylinder piston - Arrangement and the pivoting movement of the swivel arm about its horizontal swivel shaft are generated by a swivel drive device.
  • DE-PS 2654542 and DE-AS 1266213 in lifting and tilting devices of this type, a single cylinder-piston arrangement for the generation of both the lifting movements and the tilting movements provide, according to DE-PS 2654542 this cylinder-piston arrangement to attack on the lower or optionally on the upper handlebar and according to DE-AS 1266213 on the upper handlebar.
  • the cylinder-piston arrangement is to be supported at its other end on the collecting container or on elements which are fastened to the collecting container.
  • the lifting and tilting device While training in accordance with DE-PS 1201756 and DE-PS 1240776 requires two separate drive devices and the work sequence and the sequence of these drive devices ensuring control devices which require considerable expenditure on the device, it is not possible in the case of lifting and tilting devices according to DE-PS 2654542 and 1266213, the lifting and tilting device to be designed as a closed unit, which is to be mounted as such on the collection container, because the articulated support of the cylinder-piston arrangement on the collection container represents an additional assembly point with the need for coordination with respect to the swivel axis position of the swivel arm.
  • the rear articulated lever opposite the lifting and tipping frame in the articulated quadrilateral is also designed as a swivel arm which is extended upwards beyond the articulated quadrilateral and is pivotably mounted about the horizontal axis below the pouring opening.
  • the drive device for the lifting and tilting device consists of a cylinder-piston arrangement which is designed with a telescopic cylinder and which is pivotable at the lower end on the lifting and tilting frame and pivotable at the upper end on a fixed to the collecting container attached bracket is articulated.
  • the arrangement of the drive device designed in this way is laterally outside the surface area of the pouring opening.
  • the drive device designed as a telescopic cylinder thus extends along the operating area of the switching and control devices of the lifting and tilting device and, as a result, increases the risk for the operating personnel.
  • the drive device designed as a telescopic cylinder is expensive and complex.
  • the design of the rear articulated lever opposite the lifting and tipping frame as a swivel arm projecting beyond the four-bar linkage and articulated on the collecting container means that the overlap of the pouring opening with the circular-shaped tilting path of the container to be emptied is relatively small.
  • the edge of the container is therefore guided just above the swivel axis of the swivel arm over the edge of the pouring opening.
  • An inclined sliding wall leading into the interior of the collecting container is therefore required, via which the material falling from the container slides into the interior of the collecting container.
  • the object of the invention is to provide a substantially improved lifting and tipping device for emptying containers, with the use of the least possible mechanical effort, a wide coverage of the pouring opening with the path of movement of the container to be emptied and thus direct pouring of the container contents into the collection container is possible.
  • the lifting and tilting device is intended to be a compact unit which can be installed in a simple manner and with little space requirement in the area of the pouring opening.
  • the drive device is attached to the swivel drive device in the area of the pouring opening and the upper link is non-positively connected to this swivel drive device, while the rear articulated lever of the four-bar linkage is also pivotally attached to the swivel drive device and in the initial position against one in the area of the Dispensing opening with respect to the collecting container or fixedly attached contact element forms a supporting arm, and that a limiting device which becomes effective in the course of the upward movement of the upper link is provided, which prevents the further mutual pivoting of the parts of the four-bar linkage.
  • the drive device as a swivel drive device and the direct frictional connection of the upper link with this swivel drive device, on the one hand an improved efficiency of the power transmission from the drive device to the upper handlebar is achieved and on the other hand the coverage of the pouring opening through the circular path of movement of the container to be emptied considerably enlarged.
  • the rear articulated lever and the lower handlebar only take over guiding and supporting functions for the lifting and tipping frame and the container it holds.
  • the device according to the invention is also characterized by clear constructions and high operational reliability.
  • Improved guidance of the container during the emptying process is achieved by bringing the four-bar linkage, one of which has a joint in the area of the swivel drive device, into a wide-open mutual position of the four articulated levers during the upward movement of the upper link and in such a position against further mutual pivoting the parts of the quadrilateral are locked.
  • This is achieved by the limiting device which becomes effective in the course of the upward movement of the upper link and which prevents further pivoting of the four-bar linkage.
  • the upper link and the support arm are mounted coaxially pivotable in the area of the pivot drive device, the upper link having its non-positive connection with the drive device in the common pivot axis formed by the coaxial bearing has, while the support arm is freely pivoted within a specified swivel range.
  • the lifting and tipping device according to the invention can be designed particularly advantageously as a self-contained unit that only requires a single attachment point, namely the attachment point of the swivel drive device in the area of the pouring opening.
  • the swivel drive device can be arranged in the region of at least one vertical side edge of the pouring opening. This arrangement offers the advantage that the lifting and tipping device leaves practically the entire pouring opening free in its starting position, so that the filling of such goods which are not brought into containers, for example bulky goods or filled garbage bags, can be introduced into the pouring opening unhindered.
  • the safe emptying of containers which have been accommodated by the lifting and tipping frame can be ensured in a particularly simple manner in that the upper link extends essentially horizontally and parallel to the plane of the pouring opening has fixed support leg, on which the lift and tilt frame is pivotally attached to form one of the four joints of the four-bar linkage.
  • the carrier leg can extend laterally in a crank-like manner from the upper link in the region of the pouring opening.
  • the support arm can also be arranged in the region of the same vertical side edge of the pour-in opening as the upper link and, in its lower region in the starting position, can be cranked towards the center of the lifting / tilting frame.
  • the support arm can also be provided with an abutment element forming the lower limit of the swivel range, which at the same time contains the devices for the pivotable mounting of the lower link forming one of the four articulation points.
  • the abutment element of the support arm and the lower link should preferably lie essentially in the central plane of the lifting and tilting frame parallel to the direction of movement. In this way, a particularly stable position of the lifting and tipping frame in its initial position, particularly safe holding of the containers to be emptied by the lifting and tipping frame and safe guidance of the received containers during the emptying process are ensured.
  • the limiting device provided can have, in the simplest form, two stop elements which meet in the course of the upward movement of the upper link, one of which is arranged on the upper link and the other on the lifting and tilting frame.
  • the limiting device can be designed to be adjustable so that the lifting movement or the transition point between the lifting process can be carried out in this way and to be able to adjust the tilting process.
  • this additional quadrangular articulated locking which becomes effective in the course of the upward movement of the upper link, can be provided, which fixes the lifting and tilting frame and the upper link in a mutual position during the further upward movement.
  • the four-bar linkage forms a quasi-rigid structure during the tilting process, the articulated levers of which are held in their mutual position.
  • this additional four-bar lock can contain a controlled locking hook that holds the stop elements together.
  • the locking hook can be pivoted in and out of the operative position and can have a gravity arm which causes its pivoting movement.
  • a device which locks the accommodated container in the course of the upward movement of the upper link on the lifting and tilting frame can be provided, which is actuated on account of the mutual pivoting movement of the parts of the four-bar linkage.
  • this locking device for the container has a locking bar that can be pivoted over the edge of the container.
  • the locking device can contain, for example, an actuating device which has at least one roller and cam arranged on the upper link and on the lifting and tilting frame.
  • the actuating device for the locking device for the locking device can also be on one of the Handlebar provided linkage.
  • the locking device for the container can also have a one-armed lever which can be pivoted about a horizontal axis and carries the locking bar and which can be pivoted into the locking position against the force of a return device by means of an actuating element attached to the upper link of the four-bar arrangement.
  • a safety device can be provided which holds the one-armed lever and / or its actuating element in the locked position as long as the four-bar arrangement is in an upper operating position.
  • a retaining lock can be provided for the support arm, which can only be released by the relative movement of the four-bar parts after these parts have left their lower range of motion when pivoting upward.
  • This retention lock prevents the support arm from pivoting upwards even at the beginning of the movement sequence, as a result of which a pivoting movement of the four-bar arrangement begins in the stretched state.
  • Such pivoting of the four-bar arrangement in the extended state would result in the container to be emptied being pushed away in front of the lifting and tipping frame instead of being picked up by the lifting and tipping frame.
  • a spring-mounted retaining hook which extends over part of the support arm, can be provided on the device frame and an actuating cam lifting the retaining hook on the lower link of the four-bar arrangement for the formation of this retaining lock.

  • the gripping devices for the containers to be emptied, which are provided on the lifting and tipping frames of the two lifting and tipping devices, can be coordinated with one another in such a way that smaller containers can be picked up by one lifting and tipping frame and larger containers can be picked up by both lifting and tipping frames, and the swivel drive devices of both lifting and tilting devices can be activated either in synchronism or separately .
  • the upper link can be formed between two parallel link levers and a support leg extending between the two link levers essentially horizontally and parallel to the plane of the pouring opening, the two steering levers being pivotably mounted on a vertical side edge of the pouring opening and the support leg or the lifting / tilting frame attached to it extends essentially over the entire width of the pouring opening.
  • the control arm of the upper control arm is connected to a swivel drive device and the second control arm is freely pivotable.
  • both handlebar levers of the upper link are each connected to a swivel drive device and both swivel drive devices are equipped with a common control device.
  • a more favorable, symmetrical flow of force from the swivel drive devices to the lifting and tipping frame can be achieved.
  • a support arm common to both handlebar levers and a common lower link can be provided in the further developed embodiment of the lifting and tipping device according to the invention with the lifting and tipping frame extending over the width of the pouring opening .
  • the common support arm can be pivotally mounted on a vertical side edge of the pouring opening and be bent at its lower part to substantially the vertical central plane of the pouring opening, while the common lower link is arranged essentially in the vertical central plane of the pouring opening.
  • the lifting and tipping device according to the invention can be attached to the rear of the collecting container in refuse collection vehicles, in a similar manner to conventional lifting and tipping devices. Due to the special design of the lifting and tipping device according to the invention, however, it is also used on side-loading refuse collection vehicles possible, both in the embodiment as a simple lifting and tilting device and in one or the other further developed embodiment.

With the further movement of the lifting and tilting device, pivoting of the support arm 16 then begins, so that its abutment element 26 moves away under the retaining hook 57.
  • the actuating cam 60 runs from the actuating arm 59, and the retaining hook 57 falls back into its ready position at the limit stop.
  • the abutment 26 of the support arm 16 hits the actuating arm 59 and thereby lifts the retaining hook 57 in order to move below it into the starting position.
  • the retaining hook 57 then falls into its retaining position via the abutment element 26 or is pressed into this retaining position by its return spring. Since the retaining hook is raised by the abutment element 26 during the backward movement of the support arm, the actuating cam 60 of the lower link 15 remains ineffective during this part of the movement sequence.
  • a pair of lifting and tilting devices 10a and 10b is attached in mirror image fashion to the two vertical edges 21a and 21b in the region of the pouring opening 11.
  • Either of these two Lift and tilt devices 10a and 10b have their own swivel drive devices 17a and 17b.
  • These two swivel drive devices 17a and 17b are connected to a pressure medium control which enables the simultaneous operation of both swivel drive devices 17a and 17b in synchronism or separate operation of the swivel drive devices 17a and 17b.
  • the upper links 14a and 14b thereby enable very precise, uniform swiveling up and thus very precise, uniform lifting and tipping of a large vessel.
  • the mode of operation of each individual lift and tilt device 10a and 10b is explained in the same way as above in connection with FIGS. 1 to 5.
  • a swivel drive 17c and 17d is attached to each vertical edge 21a and 21b of the pouring opening 11.
  • Both swivel drive devices 17c and 17d belong to a common lifting and tilting device 10c, which is equipped with a single lifting and tilting frame 13c.
  • an upper link 14c and 14d is non-positively attached to each of the swivel drives 17c and 17d.
  • Both upper links 14c and 14d have a common support arm 23c.
  • a common support beam 28c is pivotally mounted about a horizontal shaft, which extends practically over the entire width of the pouring opening 11.
  • the wide lifting and tilting frame 13c thus formed has only a lower link 15c as a connection to the support arm 16c.
  • This only lower link 15c is in the central axis 27c of the lift and tilt frame 13c arranged.
  • There is also only a single support arm 16c which, in the example shown, is freely pivotably mounted on the drive shaft 20c of the swivel drive device 17c. Accordingly, the lower cranked region of the support arm 16c is drawn into the central plane 27c of the lifting and tilting frame 13c, that is to say approximately into the central plane of the pouring opening 11.
  • the swivel drive device 17d only carries the upper link 14d, which is non-positively attached there, on its shorter drive shaft 20d. Naturally, the two swivel drive devices 17c and 17d can only be operated in synchronism. Otherwise, the operation of the lifting and tipping device 10c according to FIG. 7 is analogous to that of the lifting and tipping device 10 according to FIGS. 1 to 5.
  • the lifting and tilting device 10e differs from the lifting and tilting device in accordance with FIG. 7 in that only one swivel drive device 17e is provided.
  • the upper link 14e On the drive shaft 20e of the swivel drive device 17e, the upper link 14e is non-positively attached and the one support arm 16e is pivotally mounted.
  • the second vertical side edge 21b of the pouring opening 11 On the second vertical side edge 21b of the pouring opening 11, only a journal 20f is attached, on which the second upper link 14f and the second support arm 16f are pivotably mounted.
