Definitions

  • the well-known air jet sieve which is used to determine the fineness or Grain size distribution of finely dispersed grain aggregates in a dry way is the subject of the present invention.
  • the screenings are placed on the screen mesh given, by means of a slot nozzle rotating below the screen fabric
  • the gas jet is blown from bottom to top through the sieve mesh and this on the Sieve lying sieve material whirled up.
  • the fine fractions of the screenings are from Gas jet entrained and through the screen from top to bottom in the Transported space below the sieve insert and from there, from the Screening machine discharged.
  • the rough proportions that are larger than that Mesh size of the respective sieve insert, can not pass through the sieve and remain on the screen after screening.
  • the object of the invention is achieved in that the screening machine with equipped with a sensor that automatically identifies the sieve used and that optionally additional information in the screening machine or directly the sieve can be saved.
  • An automated comparison of the sieve insert actually used with the Value of the mesh size of the sieve insert actually required in one associated control device represents the use of the correct sieve insert for sure. If the operator has mistakenly selected the wrong sieve insert, do so he is informed of the error by appropriate signals on the screening machines pointed out and is asked to insert the correct sieve into the sieving machine to use.
  • the information obtained from the identified sieve insert can also e.g. recorded in a storage device for logging and a further evaluation, e.g. in an electronic calculator, be fed.
  • each sieve has a machine-readable signature in the frame, from which at least the nominal mesh size can be taken. It can further specific data or information of the sieve in the machine-readable signature.
  • the machine-readable Signature of the sieve frame not only made legible by the sensor, but also also writable and / or overwritable. So additional information on the Signature of the sieve frame saved and later retrieved. This can e.g. the number of sieve use, performing cleaning and / or Inspection processes or the date of the last sieve use. All this information is stored in the respective sieve insert.
  • a sieve according to the invention with machine-readable
  • the sieve is only identified by a serial number.
  • the sieve insert is then evaluated based on the serial number all relevant data such as the mesh size in a separate unit, such as e.g. in a microcontroller control and / or database. Any serial number specific data records (mesh size, number of uses, Date of use, manufacturer information, mesh shape, etc.) assigned to the stored and stored physically separate from the sieve insert.
  • the sieve frame On the outside of the sieve frame there are horizontal stripes that open up part or all of the circumference of the screen frame are arranged and stand out clearly and in high contrast from the screen frame.
  • the barcodes can also be printed on a sticker on the outside of the screen frame is stuck on. If the sieve insert is inserted into the sieving machine, it will feel Sensor (laser) on the inner circumference of the bowl-shaped housing Screening machine is attached to the barcode without contact.
  • pens Located on the outside of the sieve frame or on the underside of the collar several pens.
  • One of the pens is different from the other pens by its diameter or length and thus gives the correct position for decoding before.
  • Each pin protrudes into the sieve when it is inserted Screening machine in a hole in the housing of the screening machine. In every hole the presence of a pen is checked by a sensor. By the Existing or by omitting individual pens, a code can be generated which can be read by the sensors in the housing.
  • a small chip in a glass case is placed at one point on the screen frame attached.
  • the chip can be irradiated and by means of a writing and Readers targeted information by radio transmission without auxiliary energy save and output.
  • the magnetic stripe On the outside of the sieve frame there is a magnetic stripe around its circumference attached, which is located in the housing of the screening machine reading and Writing instruments can be read or written.
  • the magnetic stripe is attached to a card at a low cost.
  • the card is attached to the screen insert by means of a chain or a cord.
  • the card with magnetic stripe carries the individual information of the Sieve insert to which it is attached.
  • the magnetic card is in during the screening to insert a reader on the screening machine, only then can the screening process be started.
  • Chip cards
  • the air jet sieve according to FIG. 1 has a sieve insert 4 inserted into the housing.
  • the sieve insert 4 is provided with a coding 1 on its outer circumference.
  • the coding 1 can be, for example, a bar code or a pin code.
  • the coding 1 can be stored on a writable memory 5 .
  • the writable memory replaces the coding 1 and is attached to the same place on the sieve insert 4 .
  • the sensor 2 mounted in the housing is operatively connected to the coding 1 or the writable memory 5 when the sieve insert 4 is inserted into the housing of the air jet sieve.
  • the signal read from the coding 1 or the writable memory 5 is registered and further processed in a control device 3 , which generates the desired and predefined actions on the basis of the respective signal.
  • the partial section shown in FIG. 2 shows the coding 1 or the writable memory 5 together with the sensor 2 and the control device 3 in an enlarged view.
  • the sensor 2 is replaced by a scale 7 , which identifies the sieve 4 used by its weight.
  • the control device 3 can identify the specific features of the strainer 4 used on the basis of Siebiffes.
  • the screening insert 4 shows a schematic representation of the screening machine, the screening insert 4 being identified by a magnetic card or chip card 6 and the screening insert 4 being identified by inserting the magnetic or chip card 6 into a slot in the housing of the screening machine by means of a card reader 2 and by the control device 3 can be processed further.
