Optimal conditions for visual inspection.

Semi-automatic inspection machine: automatic handling for visual control of pharmaceuticals

Our semi-automated inspection machines meet the highest standards for the quality inspection of your pharmaceutical products. Ampules, cartridges and vials with liquid and lyophilised contents, as well as syringes, are inspected visually by an operator for particles and cosmetic defects, using an automatic product handling system.

With the new generation V90+, the method developed by Seidenader has been further improved. It is consistently designed for maximum operator support and convenience in terms of visual inspection. Not only are the most stringent quality standards guaranteed; the machine makes inspection up to five times faster than a manual inspection and also effectively prevents premature fatigue.

Top Visual Inspection

  • Highest inspection quality

    High-speed rotation by servo motors whirls up particles in the container. In the operator's field of vision the container rotates for a 360° check at an individually selectable speed: Mirrors allow inspection of seal area and bottom of the container, a magnifying glass and the Tyndall effect facilitate inspection.

  • Optimum overview

    An LED feedback bar provides an optimal overview: the operator receives confirmation of the container's status in the form of coloured light markings – indicating whether it has been marked as defective or not.

  • Adjustable inspection angle

    The machine can be optionally configured so that the inspection angle can be adjusted to 60° or 75° depending on the task to be performed. Products which require different angles for inspection purposes can be inspected in one machine.

  • Individual speed

    Depending on product and customer requirements, containers can be fed through the inspection cabin continuously or intermittently. For optimal adaptation to the items, the roller diameter and the roller distances of the transport system are changed according to the shape and size of the container.

High Efficiency

  • Best performance

    Highest standards in the quality control of pharmaceutical products, at a speed of up to 9000 pharmaceutical containers per hour. In comparison with manual inspection, a visual inspection with automated product handling can be carried out more accurately, effortlessly and up to 5 times faster.

  • Versatile and efficient

    Simultaneous inspection of multiple criteria in one machine, by one person. The conditions required are created by various lighting and mirror systems. At a glance, the operator can inspect containers for particles in the product, contamination, cracks or glass damage to the bottom, shoulder and cap area.

  • Gentle product infeed

    Perfectly matched components at the infeed reduce the risk of glass breakages, so downtime is prevented. For example, a tilted container is detected immediately at the infeed star wheel and the product feed is automatically stopped.

  • Individual inspection profiles

    Inspection parameters such as rotation speed or light intensity are saved with the respective recipe in the HMI and uploaded automatically. It is therefore a simple matter to implement a reproducible setting of inspection parameters for each batch.

  • Simple format changes

    When changing to another product the machine is adapted by a quick and toolfree format change: All format parts are clearly marked and numbered. With the product recipe automatic settings are loaded. Instructions for manual changes can be saved in the HMI.

Maximum Flexibility

  • Wide range of containers

    Many different container shapes and sizes, from 0.5 to 1000 millilitres in volume. Depending on the format set, ampules, cartridges, vials and bottles with liquid or freeze-dried contents can be inspected, as well as syringes. Diameters can be between 6.85 and 95 millimetres and height up to 240 millimetres.

  • Variable production requirements

    Container infeed can take place inline from an upstream system or offline from cassettes with or without a buffer. Defective products can be categorised, and good products either removed manually using cassettes or conveyed inline to the next machine in the line.

  • Later retrofits

    When your production requirements change – new containers, different sizes, different products or other inspection criteria, new technologies, inline instead of offline operation – the modular structure of Seidenader machines allows them to undergo many types of retrofit - even many years after commissioning.

Excellent Design

  • Focusing on the operator

    Maximum support and ease of use for the operator: the optimal ergonomic design of the machine effectively prevents premature fatigue and therefore provides a basis for the highest quality standards in visual inspection.

  • Ergonomic design

    The cabin, widened to 80 centimetres, and an open leg area make for optimal working. Defective products are marked by a brief, effortless lifting of the index finger – the hand is ergonomically supported. An LED feedback bar provides an optimal overview: a coloured light indicates if a container is marked.

  • Easy handling, total comfort

    To facilitate visual inspection, a magnifying lens, adjustable mirrors and, depending on the container, product and inspection criteria, various lighting systems are available. The variable-speed transport system for the containers also considerably speeds up and facilitates inspection.

  • Intuitive operation

    The machine is operated intuitively via a user-friendly widescreen touchpanel. The software and control panel (HMI) meet the high standards of Seidenader's fully automatic inspection machines.

The inspection process

The use of different lighting systems and mirrors means that the V90+ can simultaneously inspect multiple criteria such as foreign particles in the product, contamination or cracks and glass damage to the bottom, shoulder and cap area, as well as – in the case of syringes – needle shields, surface, stoppers and finger grip. The machine can be optionally configured so that the inspection angle can be adjusted to 60° or 75° depending on the task to be performed.

Product infeed is facilitated by intake sliders which are also used on the fully automated systems. Perfectly co-ordinated components minimise pressure on containers and reduce friction. This reduces the risk of glass breakages, so downtime is avoided.

A variable high-speed rotation system driven by servo motors whirls up any particles in the container. In the cabin, the containers pass through the operator's workstation, either continuously or in cycles. The containers rotate slowly at an individually selectable speed around their own axis, so that the entire surface can be inspected for cosmetic defects. Particles which have been whirled up by the pre-rotation system are detected. A magnifying glass and the Tyndall effect also make detection easier: diffuse light causes particles to shine, like dust in the beam from a projector. Mirrors enable inspection of the bottom and the seal area.
