Description
~9til3~
The invention relates to a lift-dumping device for emptying containers into receptacles, particularly for emptying garbage containers into garbage-collecting trucks, comprising a lifting device for pic]cing-up the container, said lifting device being secured to a swivel arm or to a pair of swivel arms, said swivel arm or pair of swivel arms being tiltable abou-t a horizontal axis and being supported on a feeding device and, for tilting said swivel arm or pair of swivel arms being connected to a cylinder-piston unitorto a pair of cylinder~piston units.
In the known devices of this kind the cylinder-piston unit or pair of cylinder-piston units for tilting the swivel arm or pair of swivel arms abut against the feeding device at an interval below the support of the swivel arm or pair of swivel arms (See German Utility Patent 18 56 975, German Patent 10 21 786, laid-1:
open German Specification 12 66 213, Austrian Patent 228 719, Austrian Patent 1089 565.) This construction has the disadvantage that a substantial portion of the feeding device is integrated in the path of force between the support of the cylinder-piston unit and the bearing of the swivel arm and, therefore, it must be corres pondingly sturdy and heavy. A further important disadvantage of ;~, this known construction lies in that in garbage trucks such a low support of the cylinder-piston unit results in a substantial loss in,ground clearance. Since the feeding device on garbage trucks ; lies lower with increasing load and corresponding load on the springs and since, moreover, garbage trucks must also drive on ~ uneven terrain, for example, for emptying into the dump, a ground i clearance as large as possible, particularly for loaded vehicles, is desirable.
Therefore, it is the aim of the invention to create a d 30 lift-dumping device for emptying containers into a receptacle, .
particuarly for emptying garbage containers into garbage-collectiny ~ trucks, i.e., a device in which the path of force between the .i 11()9133~
support of the cylinder-piston unit and t~e bearing of the swivel arm is short and a ground clearance of the vehicle~ as large as possible also in the loaded state is assured.
According to the present invention there is provided a lifting-dumping apparatus for emptying a container into a collecting container, for example for emptying a refuse container into a refuse collecting vehicle, the apparatus comprising:
(i) a bearing plate device; (ii) one or a pair of pivoting arms carried by the bearing plates device for pivoting upwardly about a horiziontal axis; ~iii) a support frame for a container to be emptied, which frame is mounted at the free end of the pivoting arm or pair of arms and which frame is tiltable about a tilting axis parallel to the said horizontal axis; (iv) one or a pair of cylinder-piston assemblies for moving the pivoting arm or pair of arms and for moving the support frame, the said ; assembly or pair of assemblies being pivotally mounted on the bearing plate device and extending substantially parallel to the pivoting arm or pair of arms; (v) one or a pair of links for moving the support frame relative to the pivoting arm or pair of arms, the said one link or pair of links being pivotally connected to the bearing plate device and to the supportframe;
and ~vi) a fixed projection at the free end of the or each pivoting arm, which projection extends from the arm at that side of the arm remote from the support frame and which projection extends beyond the plane containing the said horizontal and ~ tilting axes, the or each cylinder-piston assembly being ;~ articulated to the or each respective projection at a point spaced from the said plane, and the link or pair of links being connected to the bearing plate device for pivoting about a fixed axis parallel to the horizontal axis.
Apart from achiev~ng this aim, the invention creates~
a particularly compact lift-dumping dev~ce which assures optimum ~_ -r, ~

ground clearance while the tilting force produced by the cylinder-piston unit is developed in a favourable way. The base plate constitutes a central element, which absorbs the supporting forces of the cylinder-piston unit and closes the path of force with the bearing of the swivel arm. This element can be so constructed that it is solid and strong without having to increase the weight of the entire device excessively.
In the known lift-dumping devices, in which the lift-ing device is movably attached to the swivel arm or to the pair of swivel arms and the motion of the lifting device is ~~
derived from the tilting motion of the swivel arm or of the pair of swivel arms, it is of course necessary to install the support of this device, which der;ves the lifting motion from the tilting motion, at an interval from the bearing of the swivel arm or pair of swivel arms. However, heretofore the support of the device deriv;ng the lifting motion from the tilting motion was provided on a wall of the feeding device.
- This makes it in turn necessary to construct parts of the feeding device particularly strong and solid. However, as a ; 20 ' .~, .

~ ll~)S~
favourable development and improvement of the invention the devicc deriving the motion of the lifting device from the tilting motion of the swivel arm or pair of swivel arms can also abut against the ; base plate. The func-tion of the base pl-~te as a central force-absorbing and force~transmitting element is thus f~rther emphasizecl and completed. By centralizing all these hcarinc3s and supports on the base plate the operation of the device is substantially safer and the danger of accidents is su~stantially reduced.
In an embodiment of the invention the device deriving the lifting motion from the tilting motion can be a guide rod, which is tiltably supported with one end on the base plate and wit~
the other end on an arm of a supporting arm for the container.
Said supporting arm forms the lifting device and is designed in the form of an angle lever and is supported on the swivel arm. In the lower starting position of the swivel arm or of the pair of 1, swivel arms the angle lever arm of the supporting arm which is . connected to the guide rod can be approximately vertically directeci upwards while the guide rod with its fulcrum is so adapted to the length of the upwardly directed angle lever arm, that the initial, upwardly directed ti]ting motion of the swivel arm or of the pair of swivel arms is converted into an approximately identical counter~
3 ~ tilting motion of the supporting arm in a downward direction.
Thus, a change of the initial tilting motion of the swivel arm is converted into a lifting motion of the supportinc3 arm in a particu-larly simple way.
Within the scope of the invention it is particularly advantageous if the cylinder-piston unit is provided with a simple ' piston guided in the cylinder and if the cylinder is tiltably supported on the base plate at an interval from its end. The desicJn ~30 of the cylinder~piston unit with simple cylinder and piston has the a advantage of a substantially less costly and simpler design as B compared with a telescopic position of cylinder. However, ~t identical length of stroke of the cylinder-piston uni-t and simple design a substantially greater cylinder length is required. sy supporting the cylinder-piston unit on the base plate and thus near the swivel axis of the swivel arm or of the pair of swivel arms the required long length of the cylinder can be compensatcd for without difficulties in that the bearing elements required for the tiltable support of the cylinder can be shlfted from the cylinder end to the centre region of the cylinder length.
In order to reinforce substantially and to improve the bearing and the support within the scope of the invention, the base B plate may be provided with a second base plate parallelling to saic~
first base plate, the swivel arm and the cylinder-piston being installed between the two plates and supported in the two plates.
Not only are the bearing and the support of both the swivel arm and the cylinder-piston unit substantially improved in this manner but a more or less symmetric layout of path of force between the suppo~
of the cylinder-piston unit and the bearing of the swivel arm is also created.
In lift-dumping devices according to the invention which are fitted with a device forderiving the motion of the lifting device from the tilting motion of the swivel arm it is possible, within the scope of the invention, to provide the base plate on both sides with a second base plate at an interval parallelly ; thereto, the swivel arm and the cylinder-piston unit on one side of the base plate being supported therein and in the second base plate and the guide rod of the device converting the tilting motion into the lifting motion on the other side of the base plate being .
supported therein and in the second base plate.
However, the guide rod can also be provided with a for~e(l end which extends over both sides of the base plate, which is lengthened if required. The separate second base plate for the guide rod can thus be dispensed with.

In lift-dumping devices according to the invention which have a pair of swivel arms it is expedient to install the second base plate, which additionally supports the swivel arm and the cylinder-piston unit, on the outside and the second hase plate additionally supporting the guide rod on the inside. In lift-dumping devices according to the invention with a pair of swivel arms receiving between themselves the containers to be emptied a funnel-shaped abutment and baffle which extends into the feed opening when garbage is dumped in can be installed between the swivel arms. This abutment and baffle secures the beariny and the support of both the swivel arms and the cylinder and piston units on the base plates. In particular said funnel-shaped ahutment and ~affle prevents dirt or garbage from c;e~ting to the base pla-tes.
In the design of the lift-dumping device having the guide rod as the device deriving the lifting motion from the tilting motion and having supporting arms in the form angle levers tiltably supported on the swivel arms as the lifting device it can be expedient to install the abutment and baffle on the supporting arms, preferably on the angle lever arms, which are directed upwards in the starting position of the swivel arms.
The invention will now be described in more detail, hy `~ way of example only, with reference to the drawings, in which:
Figure 1 shows a lift-dumping device accordiny to the invention in lateral view, in the lower end position.
Figure 2 shows a device according to Figure 1 in the upper end tilting position.
Figure 3 shows a device according to Figure 1 in front view without garbage container.
Figure 4 shows an enlarged represen-tation of a base-plat~
arranged in another embodiment.
~s is evident from the drawings, particularly from Figure 1, for swingingthe pair of swivel arms 2 and the guide rods a~83~
3 the cyllnder-~iston ~Init l in the starting position is arranged approximately parallel to the swivel arm 2. The base plates 5, 6 and 7 arranged parallel to each other and secured directly to the feeding device 4 serve as the upper fulcrum for the cylinder~piston unit 1, the swivel arms 2 and the guide rod 3, the function o~ which will be explainecl hereafter (se~ Fig. 3).
~ s is evident from the front view of Figure 3, the base plates 5, 6 and 7 (which function as central force-absorbing and force-transmitting elements) are arranged on both sid~s below the feed opening 4, the axis 8 of the corresponding swivel arm 2 being integrated by the base plates 5 and 6 while -the axis 9 of the guide rod 3 is supported by the plates 6 and 7. The upper fulcrum 10 of the cylinder-piston unit 1 is disposcd bel.ow thereof between the base plates 5 and 6 in the manner of a cross pivot pin.
A lug 12, which is intended for supporting the piston rod la of the cylinder~piston unit l and extends beyond the lower swivel axis 11, is disposed in the lower region of each swive]
arm 2. As is evident from Figure 2, the cross pivot pin 10, is ~ ~qceo~ ~
:~ D arrlng4-d---at an intcrval-from the upper end of the cylinder-piston ~ ~
unit 1. ~ -This measure results in a total length of the cylinder-piston unit which is greater than the interval between the fulcum -10 and the lug 12. -, As mentioned hereinbefore, the guide rods 3 whlch derive ~ ' the lifting motion from the tilting motion are tiltably supported ::
with their upper ends between the base plates 5, 7, the lower ends :~
being pivoted to the upwardly directed portion of the angle lever ~ arm 13 while at the same time, the corresponding s~pporting arm 14 ;~ and the corresponding swivel arm 2 are coaxially supported at thi.s :30 fulcrum. The horizontal portion of the angle lever 13 thus changes over into the supporting arm 14.
The sequence of motion and operation of the tilting device is as follows:
.
, 3~;) On actu~ting the cylinder-piston unit 1 th~ p~ir of swivel arms 2 moves upwards~ l~owever, the supporting arms 14 at first remain in a suhstantially horizontal position. I'he garbage container 15 is picked up and lifted vertica11y upwards but with-out carrying out a tilting motion. This mcans that the initial upwardly directed tilting motio~ of the swivel arms is converted by the guide rod into an approximately identical counter-tilting motion of the supporting arms in the downward direction. Up to this moment the cylinder-piston units 1, the swivel arms 2 and the guide rods 3 sti11 are parallel to each other. Only on exceeding the substantially horizontal line of the swivel arms 2 is the motion of the supporting arms 4,~ which is derived from the tilting motion of the pair of the swivel arms, also converted into a tiltinc) motio~
in such a way that the guide rod 3 presses the upwardly directed portion of the angle lever arm 13 downwards and in the course of the further upward tilting motion by the guide rods 3 the supportin~
arms 14 are tilted relative to the swivel arms 2 like a dumping motion, the container being tilted towards the feed opening 4 as is evident from Figure 2. During the lifting motion -the container 15 joins the funnel-shaped abutment and baffle 16 arranged between the two swivel arms 2 and secured to the supporting arms. This abutment and baffle 16 secures the bearing and the support of both the swivel arms and the cylindex-piston units on the base plates, that is to say, in such a way that dirt or garbage are prevented from getting to the base plates when the container is emptied.
While the cylinder-piston unit and the swivel arms 2 are supported on the base plates 5 and 6 in the manner de.scribed hereinbefore the guide rod 23 is secured directly to the base plate 6, or supported thereon, by means of a forked piece 24 at the upper end of the guide rod 23, said forked piece 24 extending over both sides of the base plate 6.
As is evident from Figure 1 and 2, particularly ~rom ~ llQ~
Figure 2, containers of different si~es can be picked up and emptied by the lift-du~ping device according to the invention.
The lid 15a of the container 15 is opened by means of the lid-i opening device 17, which picks up the lid 15a with its fork-shaped end pieces 17a on the pinions 15h and pushes it back during the swinging-tiltin~ motion. Ilowever, durin~ the swinging-tilting motion the pinions l9b of the container 19 which are , disposed on the lid 19a pass along the U-shaped guide rails 20 arranged on both sides of the feeding device 4, the~ lid l9a being opened by the guide rails 20 which rise rearward. In order to j avoid friction, the pinions l9b can be pivo-ted in -this case.
The supporting arms 14, 18 designed for the different containers 15, 19 are so supported that they are vertically tilt-able and, as shown dash-dotted in Figure 3, they can be folded .j during the inward travel. However, for reasons of clarity the supporting arms 18 are shown in Figure 3 not folded but unfolded.
~,'~
B ~ the arrangement of the base plates according to the invention in conjunction with the individual fulcrums of the corresponding units and devices a particularly compact lift- -i.j dumping device is created. It assures optimum ground clearance along with favourable development of the tilting force produced by the cylinder-piston unit. The base plates constitute a central element which absorbs the supporting forces of the cylinder-piston unit and closes the path of force with the bearing. Despite the solid construction of these plates the weight of the entire device is not substantially increased.

, 3~;) On actu~ting the cylinder-piston unit 1 th~ p~ir of swivel arms 2 moves upwards~ l~owever, the supporting arms 14 at first remain in a suhstantially horizontal position. I'he garbage container 15 is picked up and lifted vertica11y upwards but with-out carrying out a tilting motion. This mcans that the initial upwardly directed tilting motio~ of the swivel arms is converted by the guide rod into an approximately identical counter-tilting motion of the supporting arms in the downward direction. Up to this moment the cylinder-piston units 1, the swivel arms 2 and the guide rods 3 sti11 are parallel to each other. Only on exceeding the substantially horizontal line of the swivel arms 2 is the motion of the supporting arms 4,~ which is derived from the tilting motion of the pair of the swivel arms, also converted into a tiltinc) motio~
in such a way that the guide rod 3 presses the upwardly directed portion of the angle lever arm 13 downwards and in the course of the further upward tilting motion by the guide rods 3 the supportin~
arms 14 are tilted relative to the swivel arms 2 like a dumping motion, the container being tilted towards the feed opening 4 as is evident from Figure 2. During the lifting motion -the container 15 joins the funnel-shaped abutment and baffle 16 arranged between the two swivel arms 2 and secured to the supporting arms. This abutment and baffle 16 secures the bearing and the support of both the swivel arms and the cylindex-piston units on the base plates, that is to say, in such a way that dirt or garbage are prevented from getting to the base plates when the container is emptied.
While the cylinder-piston unit and the swivel arms 2 are supported on the base plates 5 and 6 in the manner de.scribed hereinbefore the guide rod 23 is secured directly to the base plate 6, or supported thereon, by means of a forked piece 24 at the upper end of the guide rod 23, said forked piece 24 extending over both sides of the base plate 6.
As is evident from Figure 1 and 2, particularly ~rom ~ llQ~
Figure 2, containers of different si~es can be picked up and emptied by the lift-du~ping device according to the invention.
The lid 15a of the container 15 is opened by means of the lid-i opening device 17, which picks up the lid 15a with its fork-shaped end pieces 17a on the pinions 15h and pushes it back during the swinging-tiltin~ motion. Ilowever, durin~ the swinging-tilting motion the pinions l9b of the container 19 which are , disposed on the lid 19a pass along the U-shaped guide rails 20 arranged on both sides of the feeding device 4, the~ lid l9a being opened by the guide rails 20 which rise rearward. In order to j avoid friction, the pinions l9b can be pivo-ted in -this case.
The supporting arms 14, 18 designed for the different containers 15, 19 are so supported that they are vertically tilt-able and, as shown dash-dotted in Figure 3, they can be folded .j during the inward travel. However, for reasons of clarity the supporting arms 18 are shown in Figure 3 not folded but unfolded.
~,'~
B ~ the arrangement of the base plates according to the invention in conjunction with the individual fulcrums of the corresponding units and devices a particularly compact lift- -i.j dumping device is created. It assures optimum ground clearance along with favourable development of the tilting force produced by the cylinder-piston unit. The base plates constitute a central element which absorbs the supporting forces of the cylinder-piston unit and closes the path of force with the bearing. Despite the solid construction of these plates the weight of the entire device is not substantially increased.
