DE2504077A1 - Rubbish skip emptying mechanism - has pivot buffer safety device preventing it sliding on container wall - Google Patents

Abstract

The mechanism is particularly for emptying large rubbish skips into collector vehicles, having a tipping frame with swing arms fitting over the skip sides and one or more supporting buffers for the skip front wall. The arms have claws engaging with supporting trunnions, handles etc. on the skip sides, and these move into locking slots in the claws as the skip is tilted on the buffer. Safety devices provided on the buffer (6), to prevent it sliding on the wall of the skip, are typically in the form of suction cups, magnets etc., or a locking stop (11) fitting behind the buffer, in the form of a profiled strip running across the skip wall (9). Alternately, the safety devices can comprise mating components engaging with each other on buffer and wall.

Description

Device for emptying containers, for example large garbage containers in collecting trolleys The invention relates to a device for emptying Containers, for example, garbage containers in collection trolleys that have a tilting frame with swivel arms reaching over the side walls of the container and at least one Has plant buffer for the front wall of the container, the pivot arms anseitliche Carrier elements, such as stub axles, hand brackets or the like. Carry gripping claws on which the carrier element by pivoting the container on / or iun the contact buffer moved into a locking slot.

There are tilting devices for emptying containers into a pouring device, known in particular from large waste containers in a refuse collection vehicle (DT-PS 1 226 036). This tilting device is suitable for this, for example a large-volume iUllgefäß with about 1 to 2 cbm content to be lifted safely, and into the for emptying the large-capacity garbage cans to bring the necessary location. Here, the support arms are designed so that they with the suspension claw formed at the front end on one, on the side wall of the Attack the stub axle attached to the container or a hand bracket attached there.

The stub axle is slightly above the center of gravity of the container arranged so that the existing facilities on the tilting device are sufficient, to empty the garbage can safely, and also, if necessary, in the swivel arms to shake hanging tilted state.

However, large-volume vessels are also known, which are probably in the Width correspond to the usual garbage cans, but a much greater length have, in order to now also use the known tilting devices for these large refuse containers To be able to use with excess length, it is not possible to focus on the stub axle according to the container to be attached to the side wall of the container. This results in an unfavorable center of gravity, i.e. the center of gravity lies Moved backwards below the stub axle, so that the garbage can only in the very far raised position of the swivel arms to lock his Axle stub can come in the locking slot of the claws. In this, very far In the swiveled-up state, however, the container has a strong tendency to with its the contact buffer facing end wall to slide onto this system buffer and out of the suspension claw to slip out.

The object of the invention is therefore to create a possibility by using the oversized filler containers safely with the tilting devices mentioned above can be emptied.

This is achieved according to the invention in that the investment buffer Devices for securing against sliding on the container wall are assigned.

In the context of the invention, it is advantageous that this is the investment buffer assigned security devices without major material and manufacturing costs on the front side of the container assigned to the system buffer or on Investment buffer to attach themselves or partly to the beginner and partly to the investment buffer permit.

The drawing shows an embodiment of the invention, wherein the Workflow of the tilting device is shown schematically, namely rest position dashed, intermediate position dash-dotted and fully extended tilting position.

As can be seen from the drawing, the tilting device 1 is on a Pivot shaft 2 mounted and below the pivot shaft 2 on a cylinder-piston unit 3 articulated, through which the suspension arms 4 and 5 pivoted by almost 1800 upwards can be. At the lower end of the swivel arm 4, contact buffers 6 can be swiveled stored. The suspension claw 7 is formed on the front hni of each pivot arm 5 or arranged.

If the tilting device is now carried out by the cylinder-piston unit 3 set in motion, the lower jaw 8 engages the suspension claw 7 behind the Axle stub 10 arranged laterally on the container 9. At the same time, the contact buffer is located 6 to the beveled face of the front container wall, above the Locking lug 11.

As the pivoting movement continues, the container is supported on the system buffer 6 and the stub axle 10 lies down in the Claw base 12 of the lower jaw 8 when the tilting device is in one position comes, which is slightly below the tilt position shown in the drawing, so the center of gravity S reached vertically above the pivot point 13 of the contact buffer 6, there is a relative tilting movement of the container 9 with respect to the pivot arms 5. As can be seen from the drawing, the container 9 - due to the unfavorable Center of gravity - with this high tilt position already the effort to be on the system buffer 6 to slide forward. The axis would be; mel 10 the locking slot 11 miss and slide out of the claw, so that the container 9 in the pouring device falls into it.

When shaking the container 9, i.e. during a quick back and forth Moving back in the upper tilted position occurs the same risk, namely that the Axle Cummel 10 jump out of the hook 6.

To prevent this, in the example shown is behind the System buffer 6 a locking lug 11 formed or

arranged. This locking approach 11 is a sliding of the Plant buffer 6 avoided on the container wall.

The locking attachment 11 is designed as a profile strip, and extends across the front end wall of the container 9.

The safe operation of the device can now be achieved regardless of the center of gravity S, i.e. with any container length and any Inclination angles of the container front wall. It is only necessary that the distance between the locking lug 11 and the stub axle 10 always the same, namely the same the distance between the lower edge of the contact buffer 6 and the base or locking slot 14 of the hook-in claw 7 is. The example described above is not the only one possible solution of the invention. In the context of the invention, it is also possible that the safety device against sliding in the form of suction holders, hold magnets or the like. is arranged on the system buffer.

In another, not shown, execution standard it is the same, that the safety devices contain interlocking parts, for example the part attached to the system buffer has a cam-shaped approach, and the part on the container wall attached part is a loop or eyelet reaching over this approach.

The described safety devices with locking attachment 11 or the other security devices mentioned can be installed without a large amount of material or attach to the container wall and to the system buffer without great manufacturing effort.
