There are already tilting devices and lifting and tilting devices for emptying large garbage containers known, in which a tilting frame with two protruding backwards over the side walls of the to emptying large garbage container gripping support arms is provided, which at its end by means of claws in stub axles attached to the side walls of the garbage can Pivoting the tilting frame upwards first to lift the large garbage container and then through Tipping into a pouring opening to empty. The emptied large garbage container is then pivoted back of the tilting frame tilted back, lowered and placed back on the ground. This known device makes it necessary that special on the side walls of the garbage can Parts, such as stub axles or the like, attached and to interact with the claws of the lifting and tipping device are trained.

However, there are also many containers and in particular also large garbage containers known to which such Elements on the side walls are missing and those in the area of their opening at least on the Side walls have outwardly protruding flanges.

A lifting and tipping device is already known for emptying such containers, in which a lifting truck can be raised and lowered by means of a pressure cylinder on the swing frame. This pallet truck has untei rearwardly extending support arms engaging the flanges on the container side walls while the tilting frame carries an opposing pan at its upper end. The container to be emptied must be with this Device can be inserted between the two arms of the pallet truck. He is then through the lifted support arms reaching under the flanges on the container side walls and from below pressed against the counter arms of the tilting frame. During the subsequent pivoting of the tilting frame the container is then tipped into the pouring device. He should be with his upper edge against a front frame which is arranged in the pouring opening and can be pivoted coaxially to the tilting frame place, which in its upper part has a control flap to open the container lid or lids.

This known device has a very complicated structure and has considerable shortcomings in practical operation. It has been found to be particularly flawed that the introduction of the container between the two support arms of the lift truck is particularly difficult, especially in the case of lifting and tilting devices on small wheels for emptying
Containers, in particular large waste containers

Jakob Naab, Laubenheim / Rhine

running large rubbish bins between the two Support arms need to be retracted. The support arms are inclined a little forward and down and provided on the top with rollers on which the flanges of the container are supposed to run, whereby the container automatically advances when it is lifted up to the front container system on the tilting frame. These rolls are very soon dirty, which is inevitable when emptying garbage cans, like this that they don't turn any more. The container can therefore only be placed on the support arms with exertion be moved, and it is therefore not automatically directed when the lift truck is raised the end.

Since the container flanges are initially only guided over two rollers, there is also one high wing loading. When inserting the garbage can between the support arms it is also for this reason often only with great physical exertion and sometimes not at all to completely remove the container, i.e. until it rests against a designated stop, because the container is laterally or tilted and jammed due to uneven floors on the two support arms. Not exactly The inserted container is then clamped in its incorrect position and can move when pivoting of the tipping frame no longer align itself with the pallet truck and the tipping frame. This has the consequence that the actuating bracket attached to the lid or to the lids is no longer correctly hit the locking hooks provided for this purpose, so that the lid control is not effective

and the lid is damaged when emptying the garbage can.

Another major disadvantage of this device is an increased risk of accidents, in particular by pinching a hand or an arm of an operator between the carrier arms, the rim of the bin and the opposing arms. For the solid necessary for the function of the device Pressing the upper edge of the container from below against the counter arms, it is also necessary to Design the lifting cylinder so strong that the necessary contact pressure even with the largest filling weight of the container is guaranteed. For this reason, the counter arms and the tilting frame as well the pallet truck can be made stable and heavy. Also in the known device The front frame provided must be stable and heavy for emptying large garbage containers will.

Finally, it is a disadvantage of the known device that two separate working devices, namely a lifting cylinder and two tilting cylinders are necessary, the tilting cylinders still in the Arranged inside the pouring device and are therefore exposed to constant pollution.

In contrast, the invention is based on the object of a much simpler and still To create safer working lifting and tipping device for containers, in particular large garbage containers. In particular is intended by the invention to introduce the container between the under the side Flanges of the container gripping support arms are made much easier and safer.

This is achieved by the invention in that the support arms are fixed (that is, without a lift truck) on Tilting frames are attached and one that is open to the rear and can be pivoted to a limited extent about a horizontal axis, support frame with front container abutment, which is placed under the flange of the container, which is equipped in its width with play for inserting the container and that on each support arm a counter holder at a distance above the holding frame and at a distance in front of its pivot axis is arranged while in a known manner at least one limiting the pivoting movement of the container Abutment buffer is attached at a distance below the support arms on the swing frame.

This allows the container to be emptied to be practically free and smoothly between the support arms insert into the holding frame. This can be done particularly easily and safely with large mobile garbage containers carry out. The limited pivotable mounting of the holding frame in the support arms results In the beginning of the pivoting movement of the tilting frame there is a pendulum suspension of the Container that fully replaces a vertically guided lift truck in its effect, without a special one Lift cylinder or the like. Is necessary. For the transition from the lifting movement to the tilting movement of the container is only necessary that the abutment buffer against the wall of the to be emptied The container. The upper edge of the container is brought up to the counter holder in a simple manner due to the pivoting of the holding frame that occurs when the container is lifted vertically the carrier arms.

When swiveling the container, its upper edge is relieved of the fact that the weight of the container and its contents is increasingly supported on the abutment buffer. The container can therefore if it has not been correctly inserted into the holding frame from the start, it is itself Align in the parking frame afterwards.

The invention also makes it possible to use a heavy, tilting movement into the pouring device supporting front frame superfluous. The device according to the invention can

ίο therefore trained much more easily and simply will.

Due to the improved possibility of introduction and the possibility of an independent subsequent Aligning the container also removes any risk of damage to the container or container lid eliminated when tilting.

In a further embodiment of the invention, the holding frame, the counter holder and the abutment buffers are with respect to the container and its flange coordinated in such a way that when the Container flange on the holding frame and when the abutment buffer is in contact with the container, the counter holder are still at a small distance above the container flange. In this way it is achieved that the container in the area of its horizontal position during tilting on its flanges is practically completely relieved, so that the container aligns itself with certainty afterwards, if it was initially poorly inserted into the holding frame. In a completely tipped position of the container, the holding frame is completely relieved, so that the shocks that occur when shaking are not transferred to the storage of the holding frame on the support arms. Limiting the The tilting movement can expediently take place by means of stops that act on the tilting frame itself works.

The holding frame is expediently extended to the rear via its pivot axis in order to achieve that he is fed up against the bottom when lifting the container to be emptied at all points the container flanges.

In order to facilitate the introduction of the container to be emptied, the counterholders are triangular wide contact surface designed so that its center of gravity is in front of its pivot axis.

A device for adjusting the height of the swivel frame can be within the scope of the invention Make it particularly simple, namely in the form of a limit stop for the backward movement of the tilting frame. By appropriately setting this limit stop, the device can according to the invention practically every garbage truck and the different heights of large garbage containers adjust.

Abutment buffers 27 and the counter brackets 22 are there-

The two swivel arms 11 take between 30 at so coordinated that when their support arms 13 are placed on a holding frame 15, the abutment buffer 27 on the vessel wall between each via a swivel bearing 16 on the two support reinforcement flange 2 of the container 1 and the gearmen 13 is held. The pivot frame 15 is still a narrow gap 28 remains free on genhaltern 22 its inside with a support flange 17 (Fig. 9). This ensures that the container 1 (FIG. 7) is provided, which engages under the reinforcement 35 with its reinforcement flange 2 at the further flange 2 of the container 1 to be emptied. How tilt the F i g on the holding flange 17 of the holding frame 15. 1, 2 and 7 show, the holding frame 15 is designed so far in contact with the front cross member 20 of the side that the reinforcement holding frame 15 can slide if it was originally flange 2 of the container 1 not yet fully inserted laterally . Upward play 18, for example from 1 to 2 cm to the comfortable 40, the front cross member 20 of the holding frame insertion of the container 1 retains. Likewise, the 15 is designed in the form of a pouring plate 29, the tilting frame is set in its initial position so that the support flange 17 of the holding frame 15 in the pouring plate 30 (Fig. 3) is placed over the dowel mounted in the pouring housing and prevents parts from empty garbage trucks (as the highest conceivable position of the container contents early, ie before the entire device is inserted) by a clearance 19 below the reinforcement flange 2 of the container 1 below the 45 ren of the container 1 in the pouring opening. Can fall on.

In this way, the container 1 can be practically based. In the example shown, the side supports are

The counterholders are part of the pouring-in device and the pouring-in opening, for example triangular with a flap 31 which at least partially closes obliquely downward directed large triangle side formed. This provided the two of the container lids themselves large triangle side corresponds to the support surface of the actuated, in the respective actuating bracket 4 gripping holder 22, which has locking hooks 32 fende with a corresponding covering 23 (FIGS. 4 and 5). can be provided. The mounting of the holder 22 is 60 Above the flap 31 are support abutments 33 so provided that the support surface - as arranged in, which is on the hinge 6 of the Behäl-F i g. 2 and 8 is shown - the cover 3 is automatically tilted. The movement of the flap 31 and forms an opening to the rear. This is on the one hand by curved guide strips achieved that even then the container 1 is gesteuseinem with 34 and on the other hand by linkage 35 Reinforcement flange 2 securely between the 65th. The guide strips are in the illustrated auxiliary flange 17 of the holding frame 15 and the counter-shark game made of sheet metal and attached to the inside of the Schütter 22 can be inserted when the garbage disposal sidewalls are attached. They run sideways on them tool is fully loaded and as a result of its arranged on the flap 31 roles. In the illustrated

th example, the guide strips 34 are only covered at their ends 36, while they are in the central area exposed at the top. The guide strips 34 are one when pivoting in and pivoting back Container 1 is of secondary importance, because 5 the flap 31 is essentially on the lid hinges 6 of the container 1 is supported. In contrast, the guide strips 34 for opening and closing the Flap 31 by hand for filling in bulky waste and the like is essential.

■ The operation of the device is very simple. When pivoting in the direction of arrow 38 in Fi g. 3 is first the container 1 in a vertical position Raised position until - as shown in Fig. 3 - the abutment buffer he 27 against the container wall place. In this position, the holding frame 15 has so far with the upper flange 2 of the The container 1 is pivoted so that the flange 2 extends up to a small gap 28 under the counter holder 22 has laid. When the tilting frame is pivoted further, the container 1 is tilted, and if he approaches the horizontal position, can slide completely into the holding frame 15 if he does not has been properly implemented from the start. The reinforcement flange then rises when it is tilted further 2 of the container 1 from the support flange 17 of the holding frame 15 and lies against the counter holder 22, which then hold the container 1 together with the abutment buffers 27 in a fixed, defined position hold opposite the tilting frame. As soon as the container with its lids 3 approaches the flap 31, he actuates - as shown in FIG. 4 and 5 can be seen - the locking hooks engaging in the actuating bracket 4 32. The lid hinge 6 then rests against the support abutments 33 of the flap 31 and causes that when the container 1 is tilted further, the flap 31 is displaced in front of the container and is pivoted by the link 35 relative to the container 1, as shown in FIG. 3 and 6 show around to open the container lid 3.

When the empty container is pivoted backwards, the flap 31 is again supported by the support abutments 33 taken by the lid hinge 6 into the starting position. The container will then be up tilted back into its upright position. If he has reached this, he leaves the abutment puff 27 the container wall, and the container is then pivoting the holding frame 15 in a vertical position Position on his wheels 5 deposited. During this settling movement, the container flange separates again from the counter brackets 22, and during the last pivoting movement of the tilting frame are lifted the support flange 17 and the reinforcing flange 2 from each other again, so that the container 3 can be pulled out of the holding frame 15.

For dust-free emptying of the container 1, it is sufficient if the flap 31 is at its lower edge carries a rubber blanket 37 hanging down under its own weight. The one covered by the blanket 37 The opening area is large enough to be able to switch between emptying large garbage containers even bulky items such as cardboard boxes and the like can be introduced into the pouring opening without opening the flap 31. If the garbage truck is to be used to remove bulky goods, the flap can be used in it 31 swiveled in and thereby the full pouring opening can be released.
