Definitions

  • the invention relates to an apparatus for separating metal parts from free-flowing bulk material, which forms a standing material column in a downpipe surrounded by a detector, with an ejection mechanism having a separating block and being connected to a movement by a drive element, this separating block contains the downpipe and in its eject position above one there is an open outlet and means are available which in this position close the bulk material inlet opening of the separator block.
  • the object to be achieved with the invention is to further develop an apparatus of the type mentioned at the beginning for "standing material columns” in such a way that an improved, reliable separation of foreign bodies takes place while maintaining a low overall height.
  • baffles or bulk material deflection members are arranged in the downpipe below the detector to reduce the falling speed of the bulk material.
  • the baffles or deflectors installed in the downpipe of the movable separation block prevent and delay unhindered falling through the previously emptied delivery pipe. This means that the height is low, which makes it possible to place the device directly on production machines, e.g. automatic injection molding machines, even in confined spaces.
  • the invention is therefore based on the non-obvious knowledge that a critical phase with regard to separation security only occurs when the conveyor pipe is empty after a separation process and thus the baffles or the like. must be installed in the movable separator block.
  • a separating mechanism 1 serves the purpose NEN separation block 2 with detector 12, baffles 3, 4, drive means 13 for the separation block 2 and an electronic evaluation circuit.
  • a sliding-like separating block 2 is mounted so that it can move horizontally in a straight line. This is driven by a cylinder piston unit 13, which is connected to a pneumatic or hydraulic pressure source and is controlled by an electromagnetic valve.
  • a funnel 18 for receiving the bulk material is located above the apparatus.
  • a vertical downpipe 5 is provided below the funnel 18 and a plastic ring 11 that determines the passage.
  • the apparatus is or the like directly by means of the fastening flange 6 on a production machine. attachable.
  • the separating block 2 can be displaced, so that afterwards the lower end of the downpipe 5 comes to rest on an open discharge channel 7 which runs obliquely downwards.
  • An elongated cover 8 is connected to the separating block 2 on top of the housing 9. This is designed such that it follows the movement of the separating block 2 and closes the inlet opening 17 for the bulk material in the separating position.
  • the separating block 2 shows the design of the separating block 2 in detail.
  • the separating block 2 is held on the side by two stationary guide rails 10 and is thus movably mounted in the direction of the arrow D (FIG. 1).
  • a power supply sleeve 18 connected to the separator block 2 can move into a longitudinal slot 19.
  • baffle plates 3, 4 have opposite, downward inclinations and are diametrically opposed.
  • the arrangement of these baffle plates 3, 4 is such that they overlap slightly, so that no free diarrhea of bulk material is possible. The bulk material initially hits one and then the other baffle.
  • baffles 3 and 4 Above these baffles 3 and 4 is located in the separating block 2 a detector 12 arranged around the downpipe 5 on the outside in the form of an oscillating circuit and coupling coil 14 operating on an induction basis, which are connected to an electronic signal evaluation and control device.
  • a shielding pot 16 or focusing ring is located above these two coils.
  • the metallic foreign bodies passing through the downpipe 5 in the area of the coils cause, via the detector 12, that the output voltage at an oscillator is changed, which is amplified via a differentiating stage and evaluated with a threshold compensator and a relay is controlled.
  • This detector 12 thus causes the bulk material trickling down in the direction of arrow A to drive a relay through the high-frequency oscillation field generated by the coils 12 via the control electronics, which acts on an inlet valve for the pressure medium of the cylinder-piston unit 13, as a result of which the separating block 2 together with baffle plates 3, 4 and detector 12 is moved in the direction of arrow D.
  • the bulk material which trickles down is prevented from falling freely by the baffle plates 3, 4 and subsequently arrives with a deceleration and reduced speed in the direction of arrow B into the pipe section 15 underneath and then, for example, into a production machine, which can be an injection molding machine.
  • the control signal thus generated causes the separating mechanism 1 to respond and the separating block 2 to be moved in the direction of arrow D into the separating position in which the filler tube 5 comes to lie above the separating outlet 7.
  • the inlet opening 17 is closed by the closure lid or slide 8 rigidly attached to the separation block 2, so that no further bulk material can flow in in the separation position. If the separating block 2 is sufficiently long that it directly covers the inlet opening 17 in the separating position of the separating block 2, no additional slide 8 is required.
  • the separating mechanism 1 After the foreign body together with a small part of the bulk material is discharged via the separating outlet 7 in the direction of arrow C, the separating mechanism 1 is moved back into the starting position, whereupon the bulk material can flow off again in the direction of arrow B.
  • the stationary pipe section 15 serves as a buffer for the bulk material during the separation process.
  • FIG. 3 shows an embodiment variant in which, instead of the baffle plates 3, 4, an inclined channel 20 is present in the downpipe 5.
  • the lateral deflection of this oblique channel 20 is selected so that it is larger than the diameter of the oblique channel. This prevents a foreign body from falling unhindered in the vertical direction, but must always hit the inclined channel 20, since the lateral displacement of the inclined channel is at least a distance a larger than its diameter.
  • the remaining mode of operation is the same as in the embodiment according to FIGS. 1 and 2, i.e. the separator block 2 is also moved by a cylinder piston unit 13 in the direction of arrow D.
  • the separating block 2 could also be pivotable about a vertical or horizontal axis.
  • baffle plates or other baffles serving as fall-chicane could also be provided.
  • the inclined channel 20 could also have several kinks.
