The PBMS Preform and Bottle Measuring System is an automatic instrument for measuring the general dimension of preforms and bottles. The instrument is designed according to the principle of optical multi-lens refraction and segmented imaging, and multi-segment parallel light is used to illuminate the preform to obtain the entire contour image. The contour was extracted by the bi-telecentric lens and parallel light source, which ensures that the contour is not deformed and the measurement accuracy is ensured. Auto positioning and measuring the dimensions of the preform, not only the regular dimensions like neck diameter, thread diameter and the outer diameter of locking ring, etc., but also the flashing, concentricity and overall height, etc., the instrument can also recognize and record the cavity number automatically.

Characteristics :

  • The instrument is designed according to the principle of optical multi-lens refraction and segmented imaging, and multi-segment parallel light is used to illuminate the preform to obtain the entire contour image
  • Optimal light source design, auto filter the shrinkage and grain effects caused by the injection molding of the preform, and recognize the characters of cavity number of the preform accurately.
  • Custom-made finish spacers according to the finish sizes, easy to replace and ensure the measurement accuracy
  • Preform rotation by servo motor
  • Positioning by the inherent characteristic points of the preforms, so that to standardize the measurements of all the preforms
  • Modular design, which is easier in installation, more convenient to use and higher accuracy and stability
  • System adopts measurement modular management function, and improves the measurement accuracy to 1/3~1/5 pixels (0.005mm) through the sub-pixel image processing technology of planting technology
  • Software has different built-in standard finish measurement modules, the system is able to select different measurement modules intelligently by auto identifying the preform category
  • The system has character learning and recognition functions. Based on the character pre-learning, the cavity number on the preform can be quickly identified and recorded in the data sheet
