Definitions

  • the invention relates to a device for sorting goods, too Called screening machine.
  • the invention particularly relates to a Tumbler.
  • Such a screening machine is for example became known from the prospectus "tumble screening machines" of the applicant from April 1998.
  • Devices of this type are used in very many branches of industry.
  • the food industry the chipboard industry, called the chemical industry.
  • the devices are used for Disassembly of a fleece-like or debris-capable material into solid or liquid Form, for example in the form of a suspension, in individual components.
  • On possible purpose of such a device is, for example, a granular material in different fractions of different grain sizes disassemble.
  • Another application is the separation of Impurities from a good.
  • a device of the type mentioned comprises a housing, further at least one sorting sieve, at least one inlet for the sorting Well, at least one outlet for the accept and at least one outlet for the backlog.
  • Non-contact sensors are generally known. You DE 43 21 447 and DE 44 23 223.
  • the invention has for its object a device according to the To design the preamble of claim 1 or a screening process in such a way that simple and inexpensive way to ensure that disruption to everyone Kind, especially as mentioned above, quickly and reliably recognized and can be turned off. Mind you, it's not just about recognizing and canceling a single type of fault, but also any fault that seriously affect the operation of the device.
  • the inventors have thus recognized a superordinate criterion that any kind caught by disturbances, they may occur individually or together.
  • the measure according to the invention is simple. It only requires assembly a commercially available sensor, the cost of which compared to Value of the entire machine is negligible.
  • the vote A contactless sensor is advantageous because it is not comes into contact with the goods and is therefore free of dirt or mechanical influences.
  • Such a sensor can be individual adjustment of the sensitivity with a potentiometer selective switching behavior on media with different residual conductivity adapt (for example to liquids, suspensions, dispersions or Solids).
  • inductive sensors come into consideration, but also capacitive sensors.
  • the latter are able to handle foreign bodies higher residual conductivity, for example, wire fragments the sieve bottom. They are capable of downstream product switches activate the good metal mixture from the good material flow brieflyschleusen.
  • the tumbler screen shown in Fig. 1 comprises a housing 1 with a Inlet 1.1, a first accept outlet 1.2 and a second accept outlet 1.3, also an outlet 1.4 for coarse material.
  • Two sieve trays can also be seen 2.1 and 2.2.
  • the tumbler screening machine shown in FIG. 2 in turn comprises a housing 1 with an inlet 1.1.
  • the outlet 1.3 is a sensor 3 for contactless detection of the Throughput assigned to the middle accept material fraction.
  • a sensor 3.1 is shown here - not in FIG. 2 shown.
  • Sensor 3.1 is a non-contact sensor (proximity switch).
  • the device according to the invention can be of special type assigned, for example product switches to discharge a Product-metal mixture from the accept stream. Such switches are activated when the sensor emits a corresponding signal.
