Bottle counting: technologies and used counting machines

Used counting machines for the pharmaceutical and nutraceutical sectors

In the world of pharmaceutical and nutraceutical packaging, counting solid units (tablets, capsules, softgels, candies, or dragees) is a crucial step to ensure accuracy, safety, and regulatory compliance.

Incorrect counting can compromise the entire production batch, generate complaints, and incur high costs. For this reason, counting machines are among the most critical equipment on bottle-filling lines.

How the Bottle Counting and Filling Process Works

The bottle counting production cycle can be summarized in six main steps:

  1. Product feeding – Tablets or capsules are conveyed from hoppers or vibratory feeders to the counting channels.
  2. Distribution – The product is aligned on vibrating channels or multi-lane tracks to ensure a uniform flow.
  3. Counting – Optical or machine vision technology records each individual unit.
  4. Bottle filling – Once the preset count is reached, the units are directed into the bottle in a controlled manner.
  5. Quality control – Sensors and vision systems verify that each bottle contains the correct number of units.
  6. Line integration – The bottle then proceeds to capping, labeling, and final packaging, maintaining full traceability.

Main Counting Technologies

Optical Counting

This is the most widely used technology. Tablets pass through infrared light beams, and each interruption is recorded as a unit.
Advantages: high speed, simplicity, and reliability.
Disadvantages: sensitive to dust and vibrations, requires regular calibration.

Machine Vision and AI

High-resolution cameras “see” the units in real time, while AI algorithms count them and detect defects or overlaps.
Advantages: integrated quality control and flexibility for multiple formats.
Disadvantages: higher cost and need for training.

Mechanical Counting and Weighing

Complementary methods based on vibrating channels or total batch weight.
Useful for medium-small production or lines dedicated to very uniform products.

Leading Counting Machine Manufacturers

The international market features top-tier manufacturers specializing in bottle counting machines:

  • Marchesini Group – Compact and modular lines for tablet and capsule counting and filling.
  • IMA / IMA Swiftpack / IMA Uniline – High-performance integrated solutions, suitable for fully automatic lines.

Why Choose a Used Counting Machine

Purchasing a used counting machine can be a strategic choice, especially for those looking to expand their packaging line without the costs of a new system.

Main advantages include:

  • Lower capital investment
  • Shorter delivery times
  • Possibility of customization and retrofitting
  • Environmental sustainability through reuse of still-efficient machines
