Definitions

  • the invention relates to a method and a device for sorting fluorescent lamps by Phosphor mixtures.
  • the invention is therefore based on the object a method and an apparatus for sorting Fluorescent lamps to create what sorting by Fluorescent mixtures enabled.
  • the task is based on the Process steps of claim 1 or the features of Claim 3 solved and by the further measures of Subclaims designed and developed.
  • the ones to be examined Fluorescent lamps fed to an inspection station see above that they are a predetermined distance from at least one Have camera.
  • the fluorescent lamp is rotated around the to read the imprint near the lamp base and to supply an image processing system.
  • the imprint generally includes a company logo with a Type identification from letters and numbers.
  • the Image processing system contains a memory for Pre-entry of such company logos and type designations, see above that by comparison, the respectively examined Fluorescent tube the manufacturer and the lamp type can be assigned. This will make it possible Fluorescent lamps with regard to their fluorescent mixtures to sort.
  • the print is on fluorescent lamps only at one end in a range of about 80 mm Width from the end of the fluorescent body. If used up Fluorescent lamps are delivered is the distribution arbitrarily at the end with imprint or without imprint. Around This problem can be addressed by one to provide a double pass through the detection system, before the second run the previously unrecognized Fluorescent lamps are rotated by 180 ° so that you right end passed the camera.
  • one of the cameras designed to be movable adapt to different lengths of fluorescent tubes can be between 350 and 1800 mm long can.
  • the support angles are in sufficient distance from the ends of the fluorescent lamps not to arrange the image inspection by the cameras disturb.
  • One of the support angles is made movable, around the specified length range from 350 to 1800 mm To be able to adjust the length of the fluorescent lamps.
  • Fluorescent lamps 1 are individually by one Cup conveyor 2 is brought to an infeed conveyor section 3, which consists of a sloping runway.
  • a Guide cover surface 4 ensures that the fluorescent tubes 1 horizontally aligned in an inspection station 10 arrive.
  • the illustrated Embodiment should be steeper to the rolling surface 3 standing stop surface 13 used as an inspection level become. Accordingly, the viewing directions of the cameras 21 and 22 aligned perpendicular to this plane 13, and the Distance of the cameras is chosen so that the level 13 in the Camera is in focus.
  • Each stop bracket 11 or 12 are pairs of rollers 15 or 16 assigned, the tangent to the stop plane 13 are arranged, as best shown in Fig. 2.
  • Each of the rollers 15 and 16 is a friction roller drive 17 or 18 assigned to the respective roll 15 or 16 to drive and thus in the inspection station to turn located lamp body 1.
  • the stop angle 11 and the assigned roles 15 are arranged stationary during the stop angle 12 with assigned rollers 16 in the direction of extension of the Inspection station 10 is movable, as by the Double arrow 19 indicated.
  • the shift of the Stop angle 12 together with rollers 16 can by means of a Spindle and a guide are made, which is for the sake of Clarity has not been shown.
  • the camera 22 can be parallel moved to the longitudinal extent of the inspection station 10 are, as indicated by arrow 23.
  • a Spindle and guide are used, there are also others Sliding means usable.
  • the Camera 21 is arranged stationary and on an end region the lamp body 1 aligned of 80 mm width, on the the manufacturer 's imprint with manufacturer symbol and Type identification is to be expected.
  • the movable camera 22 is directed to the respective end of the lamp body 1, and to an area of 80 mm width.
  • the two cameras 21 and 22 are with one Image processing system 30 connected by the cameras digital image information coming as pixel signals record and compare with stored image information can.
  • This stored image information relates to the expected imprints at the end of the lamp body, namely regarding manufacturer and lamp type. In general become company symbols or logos and letter-number combinations printed, the size of the print depends on the lamp type. If the lamp body 1 at the Exam is rotated and the imprint by the Field of view of the camera 21 moves, then that Company logo and the type identification in the one we are used to Order read. If, on the other hand, the symbol is printed located at the left end of the lamp body, then reads the Camera 22 the symbol imprint backwards. Processing in the image processing system takes this into account. If that Image processing system a monitor 31 for control purposes has, then this is fed so that the imprint in correct reading direction for humans appears.
  • Switch controller 32 To the image processing 30 is one Switch controller 32 connected, which ensures that the each tested lamp body is sorted correctly. This happens in a discharge conveyor section 24, which as inclined runway with a row of flaps 25 can be trained. By reversing rollers 15 and 16 will be in the inspection station 10 located lamp body over the height of the stop angle 11 and 12 raised and then reaches the runway 24, to roll down on this. Each flap 25 has a damper actuator, each with the Switch control 32 is connected. Switch control 32 has as many outputs as lightweight mixtures plus one further exit for unidentified Phosphor mixtures.
  • the respective outputs of the Switch control 32 are assigned to the flaps 25, so that upon detection of a particular class of Fluorescent tubes by manufacturer and lamp type or - types to which a certain phosphor mixture is assigned is, an associated flap 25 is opened and the rolling down fluorescent tube in one below located container lands.
  • the new sorting method enables a relative rapid determination of the class of the examined Fluorescent tube. It can take up to 2 seconds 0.5 seconds.
  • the selectivity of the Recognition of the symbol imprint is very high, being under "Symbol imprint" both the company logo and the Type marking is to be understood. Lamps whose Affiliation cannot be clearly determined in processed in the usual way. In this way will be recovered from the fluorescent tubes Fluorescent mixtures of extremely high quality recovered as not disturbed by foreign mixtures.
  • the Obtaining the phosphor mixtures from the Fluorescent tubes are opened in the usual way the fluorescent tubes and blowing out the coating with Compressed air.
