Description

DESCRIPTION OF THE DRAWINGS

[0043] In the following the invention will be described by means of an example. It is pointed out that the presented embodiment is not to be understood as a restriction of the invention. On the contrary, other modifications are comprised by the invention.

[0044] In the figures:

[0045] FIG. 1 is a three-dimensional representation of the sorting system according to the invention,

[0046] FIG. 2 is a side view of the sorting system according to the invention with a separation device for separating magnetic parts.

[0047] FIG. 3 is a top view of the embodiment according to FIG. 2.

[0048] In the following the three figures will be described as a complex, as in all figures identical features are referred to by identical reference numbers.

[0049] The sorting system I is schematically designated by an arrow. The entire system is arranged on the support unit 1. In the three-dimensional representation of FIG. 1 the receiving unit 2 is also designated by an arrow on the left hand side. The support unit 1 is in the embodiment of the representation designed as a frame. According to the invention, of course, other modifications of the embodiment of the support unit are comprised. However, the shown embodiment is sufficient for understanding. The receiving unit 2 is formed by a receiving funnel 21 that extends angularly outward to the top, while in the bottom area it has essentially vertical sidewalls. In the receiving funnel 21 a dispensing or distributing device 22 is provided. In the representation of the figure this dispensing or distributing device 22 is configured as a spreading shaft with spreading rails arranged at its diameter. At the transition zone from the receiving unit 2 to the sorting unit 3 a hand-over zone 23 is provided that has here the same working width as the subsequently arranged sorting belt 33.

[0050] Accordingly, the sorting unit 3 follows the receiving unit 2. A sorting belt 33, that can be run with variable speed, belongs to the sorting unit 3. At the end of the sorting belt 33 the replaceable and/or expandable identification sub-assembly 31 is arranged. This identification sub-assembly 31 is configured here as a housing or switch cabinet. The identification sub-assembly 31 comprises functional modules provided in the interior of the housing or switch cabinet for identifying at least one of the parts or different parts of the fraction of mixed waste. These may also be the before described detection units that contain several functional components. Thus inside the switch cabinet for example a color detection system, an infrared and/or infrared recognition system or at least an X-ray system as functional components, assembled as a detection unit may be arranged. These components can be arranged separately or combined in the identification sub-assembly. The single systems are formed generally by sensors and/or radiators that can transfer the data collected via a control to the ejection unit 4. In FIGS. 2 and 3 a separating device 32 is arranged above the sorting belt 33. The separating device 32 serves for separating magnetic parts of the fractions of mixed waste. Removal is carried out in a suitable way, for example via a suitable conveyor. In the shown embodiment the separating device 32 is designed as overhead belt.

[0051] The ejection unit 4 follows the sorting unit 3 in the direction of working a. The ejection unit 4 has a separating device for selecting the detected parts. It is arranged in a housing 41. One or more blowing nozzles for separating detected parts of the fraction of mixed waste may be provided in the housing 41. Also a separating metal plate is provided serving for separating the parts of the fraction of mixed waste accelerated differently by the blowing nozzles during falling or sinking down.

[0052] The ejection unit 4 may also have an eddy current cylinder for the separation of non-iron metals. This can be arranged in the housing. However, it may also join the housing 41. It can also take over the task of the back deflection roller for the sorting belt 33.

[0053] In the representation of the figures the side conveyors 42 and 43, provided rectangularly on both sides to the working direction a, also belong to the ejection unit 4. Arrows b and c designate the respective ejection directions of the selected or non-selected material.

[0054] Seen in the installation direction below the identification sub-assembly 31 and the housing 41 a spillover 44 is provided serving for removing non-selected parts. The side conveyor 43 in the shown embodiment serves for removing non-detected parts of the fraction of mixed waste. Via a not shown return these parts can be redelivered to the receiving unit 2. Seen in working direction a at the end of the device the drive unit 5 is provided that is designed as PowerBox. This PowerBox is configured as an interchangeable module and, for example, contains the drive motor, the energy supply aggregate, the aggregates for producing the required support energy, such as, for example, hydraulic pressure, air pressure, electric energy. In the PowerBox are also the necessary components of the data and security devices of the sorting system arranged. The module-like design of the drive unit 5 allows to operate very different sorting units with very different sorting tasks. In the case that the device is equipped with a combustion engine, this can also be arranged in the PowerBox. The combustion engine serves as primary energy supplier for producing all necessary energy.

[0055] In the figures the sorting system I is arranged on a support unit 1 that can be coupled to a low-bed truck.

[0056] The invention has been described by means of an example. However, the invention is not restricted to such example and is without prejudice for obtaining broader protection.

[0057] The sub-claims relate to further embodiments of the main claim.
