Counting Technologies

Our counting machines can be equipped with sensors not only able to count products correctly but also able to work in difficult conditions and able to verify product quality.

Counting Technologies for electronic counting machines

Optical sensor

Very reliable and accurate, infrared emitter and receiver is able to scan at very high rate (16 scans per millisecond). A detected product that falls between minimum and maximum Dark Time is considered a good product and counted. Sensors can detect and count two tablets falling closely together but not completely overlapped.

E.F.S. (Electrostatic field sensor)

Suitable for dusty products, E.F.S. is a unique sensor control able to discriminate between referenced good product and broken tablets, empty or half empty capsules. The mass of the tablet is given by a reference curve. E.F.S. is a dust resistant sensor. The system is suitable to handle both capsules and tablets and it is dust immune.

The table below indicates the detection capabilities of the optical and E.F.S. sensors for different tablet/capsule damage and scenarios. If they are not detected then they will be counted as a good product, if they are detected then the machine will reject the bottle containing that product.
  Half tablet or capsule Capped tablet Tablet chip Double tablet Double tablet Part of tablet Empty capsule Half empty capsule
OPTICAL SENSOR NO NO NO YES (count as double) NO NO NO NO
E.F.S. (ELECTROSTATIC FIELD SENSOR) YES YES YES YES (Count as double) YES (Count as double) NO YES YES
Tests with active product are needed in order to confirm definitive results.

Camera

Counting machines can be equipped with Camera Vision System to detect cross contamination (products with different colours).

Counting Technologies for slat counting machines

Trucount scanning System

The revolutionary TruCount® high speed tablet scanning system scans, evaluates and counts the product before it enters the bottle and ensures 100% count accuracy. Rather than using a vision system, the TruCount® provides a fully integrated count verification system that is reliable, easy to set up and eliminates the need for operators. A large array of photo diodes and detectors scan the product at nearly 2000 times per second after the tablet leaves the slat. Tablets are fully contained within the manifold to ensure that counted tablets enter the bottle.
