  1. What is the use of the online check weighing conveyor system?
    • It can be used to install after the customer’s conveyor line to do the check weighing automatically for each box/bag/crate/battery and rejection the under weight and over weight objects automatically based on the tolerance given in the settings.
  2. How many conveyors will come in this system?
    • Total 4 conveyors will be the part of the system.
      • Infeed conveyor - This is used to regulate the traffic of the objects coming for check weighing. This is a motorised belt conveyor.
      • Weighing conveyor - This is used to do the check weighing process. This is a motorised belt conveyor.
      • Outfeed conveyor - This is the exit conveyor of the system and also pneumatic pusher assembly will present in this conveyor which is used to reject the under and over weight objects and this pusher assembly will push it towards the rejection gravity conveyor. This is a powered roller conveyor.
      • Rejection conveyor - This is used to buffer the under and over weight objects which are rejected and it is a gravity roller conveyor which with slight inclination.
  3. Is it necessary to purchase the full system or can we purchase only the weighing conveyor?
    • For automatic process, full system has to be purchased with all 4 conveyors.
  4. What is the maximum throughput of this system?
    • It entirely depends on the size and weight of the objects. Please refer the size and capacity chart in the last page.
  5. What is the operating voltage of the system?
    • 230 V AC 50 Hz
  6. Is the controller inbuilt with the system?
    • Up to 600 mm width check weighing conveyors, the controller will be fixed along the weighing conveyor, but if the conveyor width is more than 600 mm, then the controller will be separate and designed to keep on the floor within 5 m from the check weighing conveyor system.
  7. What is the MOC of the system?
    • It is available in Mild Steel and SS304. Even in mild steel variant, the skid plates below the belt and the rollers in the powdered conveyor and gravity conveyors will SS304.
