The present invention relates to a method for returning empties, in particular bottles and cans, having a bulk input, in which the empties () are moved from an input space () past a detection unit () by a conveyor device () rotating about the longitudinal axis thereof, and further having a conveyor device for implementing said method, comprising a plurality followers mounted transversely to the direction of conveyance and spaced a distance apart. An increased throughput is to be achieved with such a method and such a conveyor device. This is achieved in that the empties () are parallelized out of the input space () by the conveyor device () and fed to the detection unit () in a field array, or in that each follower () is designed to be wide enough to hold at least two empties () side by side, and that an angular momentum is applied to the empties () at least in the detection field () of the detection unit ().

Method and conveyor device for returning empties, in particular bottles and cans

Device for taking back empty containers, in particular plastic bottles and metal cans, with a housing which has apparatuses for processing inserted empty containers, an intake chute accessible from the outside that receives empty containers as bulk material and a bottom sloping downward in direction of intake chute. Device is provided that prevents or impedes insertion of excessively large objects into device. Device provides almost unimpeded insertion of empty containers as bulk material into intake chute, and simultaneously prevents that excessively large objects can enter into the device. The bottom of intake chute has a plurality of grooves arranged side by side and running in the intake direction, the grooves flowing into a passage opening leading to the device and whose cross-section is dimensioned in such a manner that empty containers aligned longitudinally in the intake direction can pass unimpeded through the grooves.

Systems and methods are disclosed for the detection and identification of objects, wherein an illumination device emits polychromatic light in the infrared range, creating a light curtain, or an essentially two-dimensional area of light in the X and Z axis. The light from the light curtain and light reflected or transmitted by an object in the light curtain is imaged, via aperture-imaging optics, onto an aperture that is in the optical path and behind the aperture-imaging optics. The aperture is an elongated opening extending along the Z axis. A wavelength-dispersive device, such as a grating, diffracts light admitted by the aperture wavelength-dispersively in a diffraction direction along the Y axis. An image sensor detects the diffraction image and generates image signals which are analyzed to identify the materials comprising the object. An output signal may be generated in response to the material identified.
