Abstract
Separation machine (10) for separating wood-based materials from other materials, comprising: feed means (24) that convey the materials (A) on the conveyor belt (11) with which there is associated a detection unit (14) configured to detect the presence of materials of organic origin and/or metallic materials; a plurality of compressed air nozzles (12a), disposed downstream of an outlet end (13) of such conveyor belt (11) and configured to selectively push said materials downward; and a blowing device (25) for blowing air towards the wood-based materials coming from said outlet end (13) pushing them beyond a separation element (18) disposed downstream of said blowing device (25).
Claims10
A machine for separating wood-based materials from other materials, comprising:
- feed means which convey the materials on a conveyor belt with which there is associated a detection unit configured to detect the presence of materials of organic origin and/or metallic materials;
- a plurality of compressed air nozzles, disposed downstream of an outlet end of said conveyor belt and configured to selectively push said materials downward;
- and a device for blowing air toward the wood-based materials coming from said outlet end pushing them beyond a separation element disposed downstream of said blowing device wherein said blowing device comprises a collection zone, located between said separation element and said blowing device, for collecting the materials selected by said nozzles which are positioned in proximity of said blowing device and are configured to give said selected materials sufficient inertia to avoid the thrust of said blowing device.
The method for separating wood-based materials from other materials, comprising:
- a step of loading, by means of feed mean, the totality of materials on a conveyor belt a step of detecting, by means of a detection unit, the presence of materials of organic origin and/or of metallic materials to be separated;
- a step of selecting the materials by means of at least one plurality of compressed air nozzles and by means of a blowing unit, said nozzles being disposed downstream of an outlet end of said conveyor belt and configured to selectively push downward, by means of compressed air, said materials of organic origin and/or said metallic materials detected by said detection unit under the control of an electronic control unit and said blowing device being configured to blow air toward the wood-based materials coming from said outlet end, which pass above said blowing device by inertia, and to push them beyond a separation element disposed downstream of said blowing device;
- a step of collecting the materials selected by said nozzles in a collection zone located between said separation element and said blowing device in the proximity of which said nozzles are positioned, which are configured to give said selected materials sufficient inertia to avoid the thrust of said blowing device.
