Embodiment Construction

[0067] The boundaries of the radiation beams are indicated in the figure by dotted lines, while the individual rays are indicated by dashed lines. In FIG. 1 , the light source 1 is placed in a reflector 2 . The light emitted from the light source 1 is guided and projected onto the material 3 to be tested. The reflected light is converged by the lens 4, and the central beam is irradiated onto the grating 6 through the incident slit 5. The radiation is dispersed by the grating 6 into different wavelengths. A plate 7 is placed in the scattered radiation beam and has openings 8 in positions corresponding to selected wavelength positions in the spectrum. The first ends of the light guides 9 are placed in the openings 8 in the plate 7 , the other ends of the light guides are inserted one by one into the openings of the selector plate 10 , the light guides stop at the plate surface 11 . The selector plate 10 can be moved by a stepper motor (not shown) so that the detector 12 can o...

Abstract

A method and apparatus for use in the recylcing of post consumer or post industrial waste carpet or Polyamide-6 and/or Polyamide-66 containing non-carpet waste utilizes a hand-held portable device utilizing spectroscopic principles to accurately and quickly identify the material of the waste (carpet). The spectrometer envisioned for this task includes an infrared radiation source for illuminating the waste (carpet) sample, a selector for selecting a predetermined number of discrete wavelengths and a detection system to detect reflected radiation within the discrete wavelengths. The selector can be either a plate with a plurality of slots which positionally correspond to locations in a dispersed light beam according to the predetermined discrete wavelengths or a plurality of filters selected to pass the discrete wavelengths. The selection of the discrete wavelengths can either take place before the carpet sample is irradiated or can take place by selecting the discrete wavelengths from reflected radiation.

Description

technical field [0001] The present invention relates to a kind of infrared (IR) spectrometer to come to identify the method and device of consumer or industrial used waste mat, relate to a kind of use a hand-held infrared spectrometer in particular to identify consumer or industrial used A method of waste felt with an IR spectrometer having an IR radiation source that irradiates consumer or industrial used felt with IR radiation, a selector for selecting a predetermined number of discrete wavelengths of radiation and a IR detection system for detecting light reflected by consumer or industrial mat layers. The present invention also relates to a method and a device for identifying polyamide-6 and / or polyamide-66 containing materials using a hand-held IP spectrometer for classifying polyamides. Background technique [0002] Recycling waste consumer or industrial used matting material requires sorting waste consumer or industrial used matting material according to the type of ...
