Definitions

  • the invention relates to a device for sorting waste glass according to its color.
  • a device for sorting waste glass is known from DE-A1- 31 19 329.
  • the old glass pieces are moved over a transport area.
  • the color of the piece of old glass is recognized by means of a color recognition device and the piece of old glass can be conveyed out over an open edge of the transport path with a slide.
  • this known device only whole pieces or only partially broken old hollow glasses can be sorted.
  • the waste glass is broken up into fragments with an edge length of approximately 5 to 50 mm.
  • the fragments are then guided past a color recognition unit via a U-shaped slide.
  • the color recognition unit sends light through the fragment and determines the absorption of the light in the fragment. It is determined whether the fragment is colored, clear or opaque.
  • the object of the invention is to simplify the discharge devices.
  • FIG. 1 shows a sorting device according to the invention and FIG. 2 shows two side-by-side sorting devices in plan view.
  • the sorting chute in FIG. 1 is constructed from a metal angle with a leg 1 lying in the plane of the drawing and a leg 2 protruding in the direction of the viewer from the plane of the drawing.
  • the leg 2 is covered with a glass plate 3 on which fragments 4 lie flat and from the right slide to the bottom left of the drawing.
  • the angle of inclination of the slide is so large that existing frictional forces are overcome. It is approximately 30 degrees in FIG. 1.
  • the chute 1, 2 is tilted about its longitudinal axis in such a way that the fragments 4 slide against the edge (38 in FIG. 2) of the leg 2 facing the leg 1.
  • 10 - 17 fragment detection sensors are provided at several locations. At positions 10, 12, 14 and 16 z. B. color detection sensors and at points 11, 13, 15 and 17 metal detection sensors are provided.
  • An air nozzle 18-21 belongs to each of a color detection sensor and a metal detection sensor. The air nozzles are able to apply a force pulse to the fragment, which is directed in such a way that the fragment is accelerated away from the leg 1. The air nozzles 18-21 are arranged so that the air flow hits the narrow edge of the fragment. The fragment 4 is thus hit at the center of gravity. As a result, the fragment 4 is really moved in the direction of the pulse and does not perform any uncontrollable rotary movements.
  • the fragment 4 When sliding past the air nozzle, the fragment 4 is z for a very short time. B. 0.1 seconds with a pressure pulse. This pulse accelerates the fragment 4 perpendicular to the normal direction of movement of the fragment. It falls over the edge of the leg 2 from the slide.
  • a drop chute is assigned to each air nozzle 18-21.
  • the chutes are separated from one another by partitions 22 and end at the bottom on conveyors which are not shown here.
  • No air nozzle is assigned to the chute on the far left in FIG. 1. Parts are conveyed here that were not conveyed to any detection station.
  • the chute 1, 2 simply has a boundary wall 23 at its lower end. The parts that have not previously been conveyed out collide against this wall 23 and, since the parts are piled up, fall down from the slide into the chute below. This desired jamming effect on the wall 23 prevents the parts of the device from being worn out by the impact.
  • green glass is sorted out, including the other glass colors that were not sorted out at the first two sorting points.
  • the first three digits are each equipped with a metal detection sensor 11, 13 and 15 in order to exclude fragments that have metal residues from being sorted out. Such fragments that still carry remnants of metal, and also individual pieces of metal should only be sorted out at the fourth air nozzle 21.
  • This fourth sorting point can again be equipped with a color sensor 16 and a metal detection sensor 17. However, it is sufficient to provide only one light barrier which registers the passage of the fragment and allows the air nozzle 21 to respond at the right time. The fact that it is a fragment containing metal has already been recognized by the previous sorting point 14, 15, 20 with the metal detector 15 present there. The light barrier then only serves to precisely determine the time of ejection.
  • the order can also be chosen from other points of view. E.g. the air consumption can be minimized if the most frequently occurring fraction in the mixing glass is discharged last without bubbles.
  • the disks 5 - 9, against which the fragments 4 abut during sliding, are arranged next to one another with an intermediate space 24.
  • the gap 24 is so large that the air nozzles 18-21 fit through this slot.
  • the fragments 4 could each abut the front edge of each glass pane 5-9. Such a collision could cause the fragment 4 to move in an uncontrolled manner and hinder the sliding movement or also lead to an undesired removal.
  • the end of the glass panes 6, 7, 8, 9 is lifted by a few tenths of a millimeter from the leg 1 of the angle 1, 2, e.g. B. by placing a spacer.
  • the glass panes are arranged in a scale-like manner. Each time towards the end of the glass pane, the fragment 4 is rejected somewhat more by the leg 1 than at the beginning of the pane. This prevents a collision with the front edge of the pane.
  • the scale structure by a one-piece, appropriately shaped disc. Suitable openings must then be provided for the air nozzle 18-21. This disc can then completely form the angle 1,2.
  • FIG. 2 shows the same sorting device as Figure 1 in plan view. Two sorting devices are shown parallel to one another in order to describe a further detail of the sorting devices. The same parts contain the same reference numerals as in FIG. 1.
  • valve blocks 27-30 are visible, which are supplied with air via an air supply hose 31.
  • the valve blocks are connected to one another by means of connecting pipes 33 for the supply of air.
  • the valve blocks 27-30 contain air channels and electromagnetically actuated valves which can release the air flow to the air nozzles 18-21 mentioned in FIG.
  • the valve block 30 contains an additional outlet hose 32 and an additional valve for controlling the supply of fragments to the sorting channel.
  • the feed device is not described in detail here.
  • Line 34 shows the path of a piece of white glass.
  • the fragment is recognized as white glass on the color recognition sensor 10.
  • the metal detector 11 recognizes that there is no piece of metal and is not contaminated with metal residues. Because these two conditions are met, the nozzle 18 is actuated at the right time and the fragment 4 is deflected along the line 34.
  • the fragment 4 is thrown onto a plate 35, where a pile 36 of white glass fragments has already accumulated.
  • the accumulated pile 36 of the fragments protects the plate 35 against wear from the impact.
  • the heap 36 is heaped up high enough, the fragments fall in the direction of arrow 37 into the chute below. In the same way, collecting plates 35 are provided in the other chutes, but are not shown.
  • Suitable sensors for determining the type of fragments and output drivers for controlling the valve blocks 27-30 are connected to the computer via analog channels.
  • the fragment is illuminated from below with a white light beam for color recognition.
  • a plurality of optical sensors are arranged above the slide 2, which deliver analog intensity signals for different spectral ranges (for example “red”, “green” and “blue”). These signals are fed to the analog channels of the single board computer.
  • metal detection sensors 11, 13, 15 and 17 which use the eddy current loss of a coil fed with alternating current for detection.
