  • Page 17: About Metal Detection

    About Metal Detection Industrial metal detectors are used in the pharmaceutical, food, beverage, textile, garment, plastics, chemicals, lumber, and packaging industries. Contamination of food by metal shards introduced during the manufacturing process is a major safety issue in the food industry. Metal detectors are widely used and integrated into production lines and play a vital role in preventing contaminated products from reaching customers.

  • Page 18: How A Metal Detector Works

    ‘false triggering’. The robust construction and excellence in electronics and software design of Loma metal detectors provides a stable and reliable product where the likelihood of false triggering is minimised.

  • Page 19: Phasing

    Safety First Phasing The diagram below shows how the magnetic and conductive properties of a product affect the product phase angle. Utilising the ‘Learn’ feature provided in the IQ + Metal Detector, an average for the net signal received from a product during inspection is digitally processed to provide a phase angle and amplitude. This is then memorised for later recall against the product as a product ‘window’, as shown in the Product Signal diagram below and essentially provides a ‘filter’...

  • Page 20: Tracker Feature

    This could result in false triggering and rejection of good products. Loma Systems generally employ the use of fixed plastic guards fitted around both ends of the aperture. This serves a dual purpose in effectively preventing access to those areas and the accidental introduction of any metal contaminants.
  • Page 21 Each value shown is the diameter in millimetres (mm) of a spherical metal contaminant, as contained in Loma test wands. The detection performance figures quoted in the tables below are for indication purposes only and are based on previous experience with similar products and applications.

  • Page 22: Types Of Metal

    About Metal Detection Detector performance is also affected by the position of the contaminant in the aperture. The least sensitive point is located in the geometric centre of the aperture, so this ideally is where to test the detector performance each time if practical, to ensure consistency. As metal gets closer to the sides (coils) of the aperture, the signal generated becomes larger, making it easier to detect.

  • Page 23: Testing Metal Detector Performance

    Once again, if your company is a private label manufacturer, ensure that you agree upon any variation you make to testing procedures, in writing, with your retailer customers. To facilitate effective testing, all of Loma's Metal Detectors have an integral Performance Validation System (PVS) feature.

  • Page 24: Product Test Samples

    ‘Stale’ test packs may produce different product signals. Test Wands Loma Systems metal detectors are supplied with a set of plastic test ‘wands’ which contain spherical pieces of various metals in different sizes. These are convenient and easy to place into your test samples and also make the testing process even more efficient.

  • Page 25: Learn Feature

    Safety First Test reports can be automatically or manually sent directly to a printer or networked PC via LomaEnet when the metal detector is connected to a network. Alternatively the report may be saved to an SD card if fitted or to the flash disk. The test log file in .csv format may also be downloaded onto a memory stick via the USB port and then opened for analysis in Microsoft Excel.

  • Page 26: Update Learn

    About Metal Detection Update Learn The Update Learn process again consists of following on-screen instructions to pass a number of product samples through the detector aperture. This process can only be used for products that have already gone through a Full Learn process. A warning dialog will pop-up to inform you that a Full Learn is required if this has not been completed previously.

  • Page 27: Safety First

    This section provides further details. ■ Noise Levels Loma metal detectors do not emit a level of noise that is hazardous. However, in line with current legislation, the customer should verify that the overall noise levels within the operating environment are within defined limits..

  • Page 28: Safety Awareness

    This section contains details of the End User Licence Agreement for the metal detector software. Safety Awareness Loma metal detectors employ low intensity electromagnetic fields in compliance with current legislation.

  • Page 44: Mounting A Detector Head Onto A Conveyor

    Mounting a Detector Head onto a Conveyor Introduction Loma Systems have been manufacturing metal detector systems for many years and our current conveyor design incorporates this wealth of experience. There are a number of integration rules that have to be followed when fitting a new detector head to an existing or third party conveyor to attain optimal performance and avoid nuisance triggering.
  • Page 45 DRY mode. Loma metal detectors are designed to minimise any vibration or shock effects when operating with conductive products. To further enhance this resistance the conveyor must be designed with consideration to the above rules.
  • Page 46 Mounting Horizontal Heads for Use with Conductive Products Loma heads up to 350mm in height are supplied with an adjustable height mounting kit. The purpose of the height adjustment is to enable the centre line of the conductive product to pass through the “centre line”...
  • Page 47 Installation Moving metal excludes concentric rotating rollers. If they are concentric and can be guaranteed to stay that way, then they may be classed as fixed metal. However it is important to reiterate that they must be insulated from the conveyor at one end or it is possible that they will cause false triggering by creating an intermittent eddy current path.

  • Page 48: Connecting The Detector Head Electrical Supplies

    ■ Spurious Triggering The Loma range of detectors is the product of many years experience and development. They are inherently reliable, provided that it is installed and set up correctly. Remember that the detector can detect can detect moving metal anywhere within its metal free zone. This is up to a distance of 3 times the smaller of the aperture dimensions away from the detector.
  • Page 49 Installation To connect an electrical supply, proceed as follows: Remove the six front cover retaining bolts and drop down the cover until it is held against the supports Remove the screw from the top of the metal cover plate and lower it down carefully The Mains Filter is mounted inside the panel housing mounted on the right hand side.

    If on unpacking the machine it is subsequently found to be damaged, take further pictures of the damage and send them to Loma Systems. Loma Systems will then carry out an investigation, including a review of the applicable carriage terms / Incoterms, to decide what action is to be taken.

  • Page 54: Adjusting / Levelling The Conveyor

    Do not start the machine and initiate the use of any compressed air before the Loma commissioning engineer has approved the installation. Except where a metal detector head only is being supplied, all Loma metal detector systems require a clean and dry compressed air supply, primarily to operate the optional automatic reject system.
  • Page 55 Installation ■ Reject Valve – The Reject Valve is attached to the pneumatic assembly and contains five ports as follows: Air Supply Input Port – The air supply from the dump valve is connected to the input. Air Supply Output Port 1 – The air supply is fed to one side of a reject device. For example when fitted to one side of a double acting air cylinder, the air drives a rod attached to a nylon blade to push product off a conveyor into a reject bin.

  • Page 56: Connecting The Electrical Supplies

    Installation The air pressure should be set to 80psi (5.5 bar) except when being used to supply an air-blast reject device when the pressure should be set to 100psi (6.9 bar). The minimum air pressure must not fall below 65psi (4.5 bar) when the reject operates. Care should be taken when cutting the compressed air supply tube to length before fitting to ensure that no particles enter the tube as this may cause damage to or prevent the high precision air nozzles from operating correctly.
  • Page 57 Installation To connect an electrical supply, proceed as follows: Unlock and open the Electrical Services Box to access the electrical services. The back of the Isolator Switch is located in the bottom right hand side of the cabinet when viewed from the rear.
