Description

The invention relates to a roller compressor apparatus for compacting waste and recyclables in an upwardly open container, with a mounted on a pendulum joint pendulum arm at the end of a forward and zurückbewegbare driven compressor roller is fixed, which is provided on its outside with a plurality of driver elements wherein the compaction roller is formed from a carrier element connected to the pendulum arm and at least two sub-rollers, wherein the carrier element comprises a central bearing disc, on each of which a sub-roller is arranged on both sides.

Such a compressor device, as in the EP 0 042 580 A1 discloses a compaction of waste and recyclables by a rotating compaction roller in a variety of containers, the compaction roller densifies the material in layers. The compaction roller consists of two sub-rollers, which are mounted on a driven axle and parallel moved back and forth. With such a device, a significant compaction can be achieved, so that the container can hold larger quantities than in bulk.

The device is used in such a way that the operator moves the pendulum arm, which is usually provided with articulated joints in order to be able to act from a narrow side of the container, back and forth. The roller presses from above on the contents of the container and presses it to the ground. The roller rotates at the same time and engages with their driving elements in the waste. The rotation then leads to a redistribution of the waste under the roller, so that voids are closed and thereby better compaction is achieved.

The known device has been proven for a long time. There are only problems in that large-scale waste such as film residues or long strips can wrap around the roller and then affect their effect, or that waste can not be further compressed because they can not be broken, such as wooden pallets.

The object of the invention is therefore to improve a roller compressor device of the type mentioned above so that the mentioned problem wastes can be better treated and compacted.

To solve the invention, the invention proposes that the sub-rollers are each connected to a separate drive device, which is respectively mounted on the support member, and that the sub-rollers by means of the drive devices to drive the same and in opposite directions and / or to stop independently.

• – Gemäß einer ersten Betriebsweise rollen die Teilwalzen in die gleiche Richtung. Hierdurch wird das Material wie im Stand der Technik innerhalb des gesamten Containers erfasst und verdichtet.
• – Gemäß einer zweiten Betriebsweise bleibt eine Teilwalze stehen und die zweite dreht, wobei das sich unter der rotierenden Teilwalze befindliche Material zerrissen und innerhalb des Containers gefördert wird. Die stehende Teilwalze fixiert durch ihr Eigengewicht das Material zwischen Boden und Teilwalze, wobei die rotierende Teilwalze das unterhalb der Walze liegende Material weiter fördert. Hierdurch können insbesondere genagelte und geklammerte Holzpaletten auseinander gerissen werden.
• – Bei einer weiteren Betriebsweise drehen beide Teilwalzen in unterschiedliche Richtungen, wobei das Material zerrissen und in beide Richtungen innerhalb des Containers befördert wird. Dies bietet sich für weiches Material wie beispielsweise Kunststofffolien oder wenig bis leicht verholzte Grünabfälle an, in das die scharfkantigen Mitnehmerelemente direkt eindringen können, ohne eine Anpressung gegenüber dem Boden vornehmen zu müssen.

The operator can let each part roll forward or backward or even block. This results in the following compression options:

• - According to a first mode of operation, the sub-rollers roll in the same direction. As a result, the material is detected and compressed within the entire container as in the prior art.
• - According to a second mode of operation, a sub-roller stops and the second rotates, whereby the material located under the rotating sub-roller is torn and conveyed inside the container. The stationary sub-roller fixed by its own weight, the material between the bottom and sub-roller, the rotating sub-roller further promotes the lying below the roller material. As a result, in particular nailed and stapled wooden pallets can be torn apart.
• In another mode of operation, both sub-rollers rotate in different directions, the material being torn and conveyed in both directions within the container. This is suitable for soft material such as plastic films or little to slightly woody green waste, in which the sharp-edged driver elements can penetrate directly without having to make a contact with the ground.

According to a preferred embodiment, two sub-rollers are provided as half rollers of the same length, which extend on both sides of the carrier element to the outside. This results in a symmetrical arrangement.

It is also possible to provide more than two sub-rollers, whereby different lengths can be provided. To increase the crusher effect counter-rotating rollers, for example, central sub-rollers of greater length may be provided and the edge of which shorter sub-rollers, which are driven independently.

The invention will be explained in more detail with reference to the drawing. The figures show in detail:

1 a roller compressor device in use in a container from above;

2a - 2c the roller compactor device in different modes, each in a perspective view; and

3 the roller compactor device from the front.

• – ein Grundgestell 20 mit nach vorne weisenden, einen Container 200 umfassenden Füßen 23;
• – einen am Grundgestell 20 gelenkig gelagerten Knickmast 21,
• – einen am Ende des Knickmasts 21 gelenkig gelagerten Pendelarm 22 und
• – eine am Ende des Pendelarms 22 angeordneten Verdichterwale 10.

1 shows a roller compactor device 100 which is stationary in the illustrated embodiment, and which essentially comprises:

• - a base frame 20 with forward facing, a container 200 comprehensive feet 23 ;
• - one on the base frame 20 articulated articulated mast 21 .
• - one at the end of the kink mast 21 articulated pendulum 22 and
• - one at the end of the pendulum arm 22 arranged compressor whales 10 ,

The base frame 20 is designed so that it is on a narrow side of an open-topped container 200 or a Absetzmulde can be positioned.

The compressor roller 10 consists in this embodiment of two rotatable half rollers 11 . 12 on both sides of a support element 14 are arranged, which with the end of the pendulum arm 22 connected is.

According to the invention, the half rollers 11 . 12 individually driven, blocked or operated at idle. In the presentation of the 1 is indicated by the block arrows, as the upper half roller 11 when compressing the underlying material moves to the left. At the lower half roller 12 the direction of rotation is reversed. By this mode of operation are just in the border area between the half rollers 11 . 12 strong shear forces exerted on the material to be compacted, through which larger pieces of material can be torn.

This mode of operation is also in the perspective view of a compressor roller 10 in 2a shown. The curved arrows indicate the opposite directions of rotation of the half rollers 11 . 12 that result in different directions of conveyance, which is indicated by the linear block arrows below.

2 B shows how the half rollers 11 . 12 rotate in the same direction, which under the entire compressor roller 10 material is less severely torn, but mainly by the over the half rollers 11 . 12 exerted pressure is compressed.

2c schematically shows how the right half-roller 12 is blocked, so they only down, toward the bottom of the container 200 acting pressing forces on the material exercises, but does not promote the good causes. At the same time, the rotation of the other half roller 11 a linear promotion. Large pieces of waste, some under the right half-roll 12 trapped and by their entrainment elements 19 are held in a form-fitting manner, are exposed to such considerable tensile forces and torn when they with other parts in the range of action of the left half-roller 11 devices.

3 shows parts of the compressor device 100 from the beginning. Above the compactor roller 10 are parts of the pendulum arm 22 recognizable. Attached to the pendulum arm is a support device 14 , at the top a flange for connection to the pendulum arm 21 is formed and the down in a narrow, annular bearing disc 13 expires, from the outside only the narrow outer edge is recognizable. Inside the compressor roller 10 or inside the respective half-roller 11 . 12 are drive motors 17 . 18 arranged, which are each flanged with its housing to the bearing disk and with its rotor a half-roller 11 . 12 wear.
