Custom-made ejectors for your packaging lines

For 15 years, SEMSO has been manufacturing ejectors for packaging lines in the French and European industrial sectors.

Our aim is to equip as many lines as possible with ejectors to remove defective products following quality control or to load machines by transferring the product by sliding in a controlled manner.

Our ejectors are used in the following situations:

  • Ejecting chocolate bars
  • Ejection of defective cardboard packaging and bottles
  • Thermoformer loading by ejector
  • Slide-in food loading (pies, steaks...)

Description of a product ejector machine

A product ejection machine allows you to divert unwanted products on your packaging line. This machine offers rapid inspection with the utmost precision at a rate of up to 500 strokes / minute. SEMSO offers you a versatile, high-speed product ejection machine to reduce production cycle costs. Our machines are fully configurable and adaptable to your needs.

How does a non-conforming product ejection machine work?

Following detection of a non-conforming product or a machine loading top, the position controller drives the digital axis. The axis docks the product at very high speed, and the ejection stroke is performed with the product in contact until it is completely transferred. The axis returns to its initial position until the next top.

its brushless linear motor can work directly in contact with the product, or drive a pusher arm with integrated guidance depending on the nature and environment of the product to be ejected.

What are the advantages of a product ejection machine?

A product ejector is an ideal complement to a checkweigher, removing non-conforming products from your line. This machine ensures 100% compliant production and offers many advantages:

  • Reliable, long-lasting machine with fast ejection rate
  • Compatible with cameras and line control systems
  • Stainless steel structure and a brushless linear motor
  • Easy to handle and clean
  • Compliant with industry regulations

Optimize your production with SEMSO, specialists in the food and pharmaceutical industries

SEMSO integrates linear motors into most of its machines and masters the management of digital axes.
The linear motors used are cleanable with water jets and disinfectant solutions.

Our ejectors are suitable for high-speed packaging lines and have been tried and tested in several industrial plants.

We are manufacturers of customized industrial ejectors, designed to guarantee the automatic, rapid and safe exclusion of non-conforming, incorrectly positioned or foreign products, directly on production or packaging lines. Our ejector systems integrate perfectly into high-speed industrial environments, where sorting reliability and smooth flow are critical.

Our industrial ejectors can be triggered by various detection devices: optical sensors, machine vision, dynamic weighing, barcode reading, integrity control or marking. Each ejector system is designed according to the nature of the product to be excluded (solid, flexible, fragile, packaged liquid) and the constraints of speed, ejection frequency and available line space.

SEMSO offers several ejection technologies: by pneumatic cylinder, rocker blade, high-pressure air jet, motorized pusher or retractable trapdoor. These devices are PLC-controlled and synchronized in real time with detection and conveying equipment.

Technical features of our industrial ejectors:

  • Reaction time < 100 ms for high speeds
  • Stainless steel or painted steel design depending on environment (food processing, pharmaceutical, logistics)
  • Operator safety ensured by enclosures, presence sensors and servo-controls
  • HMI interfaces for setting thresholds and monitoring ejection events
  • Rejection history and traceability of non-conformities integrable into quality systems

As a manufacturer of industrial ejectors, SEMSO guarantees its customers accurate and reliable elimination of non-conforming products, helping to improve quality, reduce scrap and optimize overall production yield.
