Device for picking up and tilting a container

The invention relates to a device for picking up and tilting a container according to the preamble of the claim

In a device of this type known from DE-OS 32 16 483, a lower portion of the rocker arm / the form Lift arm, the handlebar and the associated section of the lift-tilt frame a parallel linkage. When picking up the container, the lifting arm and the handlebar come very close to each other, so that they are a part of the body or an item of clothing of an operator and / or any other Can clamp part between them. The piston-cylinder arrangement consists of a single piston-cylinder unit, with which not in desirable Way, the movements when picking up and tilting can be precisely separated from each other; rather exists the danger that these movements will merge.

The object of the invention is to provide a device according to the preamble of claim 1, which with simple Construction and low susceptibility to wear and tear, even stricter accident prevention regulations, and a clean one Separation of the movement processes when picking up and tilting the container is permitted.

The solution to this problem is given in principle in claim 1. The longitudinal guide ensures that there is always a the specified minimum distance between the lift arm and the handlebar is maintained. A particularly precise separation of the movements between the recording process and the tilting process is guaranteed by the features of claim 2.

VV *

An embodiment according to claim 3, in particular in the embodiment according to claim 4, works particularly efficiently.

The device in the embodiment according to claim 5, preferably claim 6, is particularly versatile.

The invention is explained below using two exemplary embodiments with reference to the accompanying drawings,

Fig. 1 shows the device schematically before picking up and tilting a container /

Fig. 2 shows the device according to Fig. 1 with the container received,

Fig. 3 shows the device according to Fig. 1 with the container tilted,

Fig. 4 shows a modified embodiment of the device before a large container is picked up and tilted.

The same reference numbers denote the same parts.

The device according to FIGS. 1 to 3 is used to pick up and tilt a garbage container 50 into a garbage collecting vessel 2. A tilting arm 8 is articulated below a filling opening 6 of the collecting vessel 2, at its upper end at an obtuse angle a support fork 16 for the container 50 is attached. At a distance from the lower end of the rocker arm 8 is on the Tilting arm 8 articulated a lifting arm 10 which can be pivoted up to a stop 14 on the tilting arm 8. At the bottom of the The tilting arm 8 is in a slot guide 36 projecting upwards at an acute angle from the tilting arm 8, which is a longitudinal guide represents, a link 30 is articulated. The free

Ends of the lifting arm 10 and the link 30 are articulated on a lifting and tilting frame 12 for the container 50.

On the side of the tilting arm 8 facing away from the lifting-tilting frame 12 there is one of two piston-cylinder units formed piston-cylinder arrangement 2 2, 48 provided, which is articulated on the collecting vessel at the articulation point 46 and on an extension 19 of the lifting arm 10 at the articulation point 2 is hinged.

The first piston-cylinder unit 48 is also articulated to an eye 13 of the tilting arm 8 and the second Piston-cylinder unit 22 on an eye 17 of the tilt arm.

The articulation point 44 of the tilting arm 8 on the collecting vessel 2, the articulation point 18 of the lifting arm 10 with its extension 19 on the tilting arm 8, the articulation points 28, 32 of the lifting arm 10 and the steering arm 30 on the lifting / tilting frame 12 are in cooperation with the moving articulation point of the link 30 in the slot guide 36, taking into account the position of the other articulation points 46, 13, 17, and the existing lever ratios selected so that when a control valve (not shown) for charging the two piston-cylinder units 48 with a pressure medium is opened, inevitably first the lifting arm and the link 30 and then the tilting arm ^{8 are} pivoted when the container 50 is picked up and tilted.

When picking up, the picking up process is ended when the lifting arm 10 has hit the stop 14 and therefore the upper edge of the container 50 rests against the support fork 15 or at a close distance from the support fork 16 is and

that a stop 25 on the lifting-tilting frame 12 on the forward-facing side of the upper end

of the lift arm 1o abuts (see Fig. 3).

The tilting process then follows, which ends when the piston of the piston-cylinder unit 48 hits the piston stop moves.

To pick up the container 50 through the lift and tilt frame, a receiving strip 21 on the lift and tilt frame is used,
which engages over a projecting edge of the container 50 / and a stop 27 at the lower end of the lifting-tilting frame 12, which surrounds the container 50 somewhat and therefore a. Lateral slipping of the container 50 is prevented.

In the embodiment according to FIG. 4, arms 63 on the hook 62 which can be swiveled to the side are attached to the lifting-tilting frame 12
Reaching under the support pin 61 is articulated on a large container 60.

From the comparison of FIGS. 1, 2, 3 and 4 it can be seen that when picking up and tilting a container 50 or 60
the distance between the lifting arm 10 and the handlebar 30 hardly decreases, so that lifting arm 10 and handlebar 30 nothing between
can get caught.
