Definitions

  • the invention relates to an air jet sieve according to the preamble of claim 1 and a sieve set for an air jet sieve.
  • GB-A-2321528 describes a sensor on a screening machine which serves the purpose of read a barcode on the screen, creating a central control of the screening machine the Scree. and thus knows which sieve is being weighed. This The procedure is to avoid errors by double weighing the same sieve.
  • JP 05054042 A describes Method and device for automatic inspection of powdered articles by means of a scale and at least one barcode reader.
  • the invention proposes a automated detection of various parameters of the sieve insert enable.
  • the mesh size of each used Sieve insert are automatically detected by the screening machine.
  • An automated comparison of the sieve insert actually used with the Value of the mesh size of the actually required sieve insert in one associated control device provides the use of the correct sieve insert for sure. If the operator mistakenly chose a wrong sieve insert, so He is by appropriate signals on the screening machines on the error and is prompted the correct sieve insert in the screening machine use.
  • the information obtained from the identified sieve insert may also be e.g. recorded for logging in a memory device and another evaluation, e.g. in an electronic calculator, be supplied.
  • the mesh size of each sieve insert automatically each sieve carries a machine-readable signature, from which at least the nominal mesh size is removable. It can further specific data or information of the sieve in the be stored machine-readable signature.
  • the screening machine is a sensor attached, which can read the signature. The read by the sensor Data and information can be further processed in an evaluation unit, and based on this information the desired actions are initiated. So can occur when detecting a wrong screen by the sensor and the Evaluation unit generates a warning that is due to the Siebverwechslung points.
  • the machine-readable Signature of the screen frame not only readable by the sensor, but also writable and / or overwritable. So additional information on the Signature of the screen frame stored and retrieved later. This can e.g. the number of sieve use, the implementation of cleaning and / or Control operations or the date of the last sieve use. All this information is stored in the respective sieve insert.
  • the sieve is identified only by a serial number.
  • the Evaluation of the sieve insert is then based on the serial number regarding all relevant data, e.g. the mesh size in a separate unit, such as e.g. in a microcontroller control and / or database.
  • Each serial number specific data sets (mesh size, number of uses, Date of use, manufacturer's information, mesh shape, etc.) assigned, the physically stored and stored separately from the sieve insert.
  • the barcodes can also be printed on a sticker on the outside of the screen frame is glued on. If the sieve insert is inserted into the screening machine, it will feel Sensor (laser) located on the inner circumference of the bowl-shaped housing Screening machine is mounted, the barcode contactless.
  • each pin protrudes when inserting the sieve insert into the Screening machine in a hole in the housing of the screening machine. In every hole the presence of a pin is checked by a sensor. By the Presence or omission of individual pins can generate a code, which can be read by the sensors in the housing.
  • a small chip in a glass case will be at one point of the screen frame attached.
  • the chip can by irradiation and by means of a writing and Reader by radio transmission without auxiliary energy targeted information save and spend.
  • a magnetic strip over the circumference attached On the outside of the screen frame is a magnetic strip over the circumference attached, which is located on a located in the housing of the screening machine reading and Writing instruments can be read or written.
  • the magnetic strip is mounted on a card.
  • the card is attached by a chain or string to the sieve insert.
  • the magnetic stripe card carries the individual information of the Sieve insert to which it is attached. During the screening, the magnetic card is in to introduce a reader on the screening machine, only then can the screening process to 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 barcode or a pen 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 of the sieve insert 4 .
  • the mounted in the housing sensor 2 is connected to the coding 1 or the writable memory 5 in operative connection when the sieve insert 4 is inserted into the housing of the air jet sieve.
  • the registration and further processing of the signal read by the coding 1 or the writable memory 5 takes place 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 and 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 balance 7 , which identifies the sieve 4 used in its weight.
  • the control device 3 can identify the specific features of the strainer 4 used on the basis of Siebiffes.
  • the sieve insert 4 shows a schematic representation of the screening machine, wherein the sieve insert 4 is marked with a magnetic card or chip card 6 and the sieve insert 4 identified by the insertion of the magnetic or chip card 6 in a slot in the housing of the screening machine by a card reader 2 and by the control device 3 can be further processed.
