Capsule Inspection System handles 220,000 capsules/hr.

Press Release Summary:

Based on X-ray technology, Model KKK 3900 delivers weight identification, foreign particle detection, length measurement, and deformation recognition in one process step with minimal interference. System can be installed after any capsule filling machine and achieves output up to 220,000 capsules/hr. Capsules that are not in line with desired requirements are discharged individually. Real-time image evaluation resists vibration, air flow, and dampness.

Bosch Introduces Compact Inspection Unit KKX 3900 for Capsules

Quality control with x-ray technology
  • Weight identification, foreign particles detection, length measurement
    and deformation recognition in only one process step
  • Output of up to 220,000 capsules per hour
  • Real-time identification of process relevant data

    At Achema 2012 in Frankfurt/Main, Germany, Bosch Packaging Technology introduces the new inspection unit KKX 3900 for capsules at its booth (C70, C72) in hall 3.1. Based on x-ray technology, the machine serves as a system for comprehensive and 100 percent weight and quality control. The small inspection unit is equipped with soft x-ray technology and an associated sensor for image creation.

    "The KKX 3900 is universally applicable and apart from filling weight control provides further advantages. For the first time, an inspection unit is capable of simultaneously checking all quality features like weight, foreign particles, deformation of capsule top and bottom, as well as length," explained Melanie Beck, product manager at Bosch Packaging Technology.

    Complete process control through digital image evaluation

    The KKX 3900 is used for the inspection of filled hard capsules. It can be installed after any capsule filling machine and achieves an output of up to 220,000 capsules per hour. The 100 percent inspection of filling weight is based on x-ray technology. Apart from the 100 percent inline weight control, the digital image evaluation gathers further information. "Besides filling weight information, the system also measures the length of capsules.

    Additionally, foreign particles in the filling product or capsule material are detected. Therefore, capsule quality is examined comprehensively and in one single process step," said Melanie Beck. Capsules that are not in line with desired requirements are discharged individually. The innovative realtime image evaluation resists vibration, air flow and dampness.

    The system provides several financial and pharmaceutical advantages. The combination of four measurement systems in one compact unit with minimal interference leads to reduced space requirements as well as lower costs and allows for significant increase in productivity. The individual discharge of capsules that are not in line with requirements yields a higher output. Furthermore, complete process control enhances the security of subsequent processes and, as a result, saves even more on costs. So far
    capsules had to be checked individually or in downstream processes.

    Capsules that were not closed correctly could re-open when packaged into blisters and cause significant product damage. With the KKX 3900, the first capsule inspection unit is available checking different, process-relevant data in real-time.

    The exact process control adopts several functions of visual systems for error identification. Further process control features are currently being developed and can be activated by software updates. The system is easy to use. The qualification of the machine is a quick and uncomplicated procedure and adjustment is automatic.
