Automatic Vision for PLM's Bottle Line.When PLM (Product Life cycle Management) A comprehensive information system that coordinates all aspects of a product from initial concept to its eventual retirement. Sometimes called the "digital backbone" of a product, it includes the requirements phase, analysis and design Redfearn wanted to install a high speed inspection system to check the decorated bottles coming off production lines at their Barnsley plant, they identified the Checker check·er n. 1. a. One, such as an inspector or examiner, that checks. b. One that receives items for temporary safekeeping or for shipment: a baggage checker. 2. system from Image Industries Ltd, tel:0137 272 6150, as suiting their requirements. PLM Redfearn manufacture bottles for soft drinks and other beverages, and are often required to produce bottles with shrinkwrapped sleeves for the 'designer' drink market. This Checker system has been installed on two of their lines and the automatic system is being used to check that a sleeve has been applied and is in the correct position on each bottle. Any incorrectly sleeved bottles or those with no sleeves on are automatically ejected. Some 250 bottles a minute are produced on each line and the fast shutter speed In a still camera, the length of time that the shutter is open, exposing the film (analog) or CCD or CMOS sensor (digital) to light for a single image. In a camcorder, the shutter speed is the frame speed; for example, 24, 30 or 60 frames per second (fps). See exposure and shutter lag. of the Checker system camera ensures a blur-free image is obtained when capturing an image of every bottle. During the production process, the PVC PVC: see polyvinyl chloride. PVC in full polyvinyl chloride Synthetic resin, an organic polymer made by treating vinyl chloride monomers with a peroxide. sleeving is cut to length and fed on to each bottle before it passes through a heating system which shrinks the sleeve to fit the bottle. using back-light, the vision system captures an image of the bottle profile to ensure the sleeve has been positioned correctly. The presence of a reject causes a signal to be sent to a solenoid solenoid (sō`lənoid'), device made of a long wire that has been wound many times into a tightly packed coil; it has the shape of a long cylinder. , which automatically pushes the bottle from the line. |
