Vial Freeze-dried Automatic Inspection Machine
Applications
It is mainly used for the automatic inspection of visible impurity and appearance defects of mold-formed or tube-type vial of freeze-dried injection.
Working principle
This machine consist of the following main parts: bottle infeed conveying mechanism, transitional of star wheel mechanism, dial inspection mechanism, camera and light source tracking mechanism, bottle outfeed of star wheel separation mechanism, serve motor control mechanism, body and protective cover mechanism, etc.
When the bottles were pushed into the conveyor belt, the horizontal conveyor belt will transport them to the bottle infeed star wheel which will separate the bottles equidistantly and continuously transport them to the correspondent bottle rotated holder in dial inspection area. The pressure head corresponds to the bottle rotated holder will be seized by detected bottles to ensure that the pressure head, bottle and bottle rotated holder form into independent inspection unit and rotate uniformly. After entering the inspection area, while the bottles rotate up to one circle, the high-speed camera will take photos for them. The inspection consist of six stations: a capping defect inspection station, a bottom defect and visible pharmaceuticals defect inspection station, four body and pharmaceuticals detect inspection stations. If any defects existing in the inspected bottles, they can be adjudged through comparison of multiple frame image. When the bottles are transported to the outfeed star wheel, they would be released by the correspondent pressure head through the cam gear devices. Then the bottles finished inspection will enter the outfeed star wheel and be separated into qualified and unqualified by bottle eliminated mechanism.
Inspecting Items
container’s appearance, sealing defect etc. such as the aluminum composite cap if it is completed. the sealing cap if it is uniform and beautiful (e.g rolling slanting, trimming, buckling , rubber plug.the transparent part of upper body if there is freeze-dried dot formed by splash.
the lower part of the bottle if it is uniform and no missing, if there is visible impurity at the surface and bottom crack,the capacity )

Main Technical Characteristics
Inspecting precision is adjustable. It meets with various inspection requirements of different projects.
Adopt conveyer with patented technology design to make sure the product is transmitted smoothly and the testing result is good.
Adopt servo motor control in multiple sites instead of traditional mechanical transmission to reach complete butt joint of control and inspection program to improve the accuracy of projects.
Taking the advantage of speedy locating pin design, the size parts were changed more easily and the adjustment is more convenient.
What we used is the imported 50 times amplified high resolution industrial camera. Via play light on the inspected objects directly makes the defects more visible, so the inspecting accuracy and effect are far better than manual inspection.
With six-stations, all of the detects can be inspected thoroughly.
All critical parts were processed by precise CNC machine. It makes sure the parts are in good accuracy and quality
The appearance of the machine is beautiful and generous. And all of the parts (bedplate, baseplate etc.) were managed with particular protection coating.
The driving bearing, electrical components, machine vision system and other critical components come from domestic or foreign international well-known manufacturer.
