Publication number: 20090090659Abstract: A method for counting and validating discrete articles to be introduced into containers, and an apparatus for actuating the method, which method includes distancing the articles from one another in a thinning-out section, and making the articles cross a detection zone such as to induce a consequent reactance variation in at least a variable reactance sensor. According to a reactance variation, an output signal of the variable reactance sensor takes on a specific waveform, the output signal being sent to an input of a processing unit. The processing unit provides in output data relating to a number of the articles which have passed through the at least a detection zone, a wholeness thereof as well as a passage of objects of a different nature from the articles into the detection zone.Type: ApplicationFiled: October 7, 2008Publication date: April 9, 2009Applicant: MARCHESINI GROUP S.P.A.Inventor: Giuseppe MONTI

Patent number: 7205498Abstract: A system is disclosed for detecting or inspecting for a lining of a container closure that is formed of a sheet metal and has a panel on an inside surface of the closure. The panel of the closure has a lining formed thereon. The system according to the present invention includes a conveyor for moving plural closures longitudinally and substantially through the system, a color sensor that inspects the panel of each one of the closures on the conveyor for a predetermined color, and a separator that is capable of removing closures that lack the predetermined color. The system may include an oven downstream from the sensor to bake the lining. Thus, the system automatically identifies and removes the closure having the deficient color from the conveyor. A corresponding method for identifying and removing a closure having a deficient color is also disclosed.Type: GrantFiled: February 6, 2004Date of Patent: April 17, 2007Assignee: Crown Cork & Seal Technologies CorporationInventors: Gerald M. Gresko, Daniel L. Brant

Patent number: 5755335Abstract: The invention provides a method of and apparatus for inspecting a label applied to a container. The method includes the steps of placing the container on a rotatable platform; rotating the platform; detecting an edge of the label as the container rotates on the rotating platform; stopping rotation of the platform at a predetermined position relative to the position of the detected edge of the label; advancing the container to a label inspection station; viewing the label using a machine vision label inspection system; comparing an image obtained by the machine vision inspection system with established criteria to determine if the label meets predetermined standards for the label; and selectively directing the container to a reject outlet if the label does not match the predetermined standards for the label.Type: GrantFiled: July 26, 1995Date of Patent: May 26, 1998Assignee: Steinmetz Machine Works, Inc.Inventors: John Michelotti, Ken P. Berlingo, Brian P. Romano, Brian E. Schwerkolt

Patent number: 5499718Abstract: A method and system for temporarily halting an article for sensing with a fixed sensing system without altering its average speed. While halted, the article's orientation is manipulated for seeking and presenting a specific area thereon for sensing. The time available for manipulation results from accelerating each article relative to the average speed of articles prior to sensing. The sensing of the article includes visually reading a label thereon to identify the article, and inspection of the article for determining its physical condition. If desired, the physical condition of the article such as a glass bottle may also be evaluated without halting movement thereof. Once the article has been identified and inspected, the article is categorized based on the visual information obtained. Articles in certain categories are rejected from those evaluated.Type: GrantFiled: January 20, 1995Date of Patent: March 19, 1996Assignee: Videojet Systems International Inc.Inventors: Chandrakant R. Bhatia, Richard J. Kuhns, Steven D. Vannice, Michael E. Stober

Patent number: 4437985Abstract: A color monitoring device includes a mechanism for removing containers from a path and accurately positioning a preselected area with a color monitor. The color monitor produces an output signal representative of the area being monitored which is amplified and fed to a computer where it is compared with reference signals. If the output signal is outside prescribed limits, the container is rejected, and if it is within prescribed limits, the container is returned to the path. A shuttle mechanism is activated by the computer and automatically removes a container from the path while returning a previously inspected container to the path. Stepper motors are used to vertically and horizontally position a selected point in front of the colorimeter.Type: GrantFiled: May 18, 1981Date of Patent: March 20, 1984Assignee: National Can CorporationInventors: James J. Hinds, John C. Hoeflich, George C. Kolodziej

Patent number: 4316533Abstract: A machine for refunding the deposit on empty containers such as bottles or cans for encouraging their return is disclosed. The machine includes an access door through which an empty container is introduced to an inspection station whereupon an inspection device determines if the empty container is marked with a proper identifying mark unique to that brand of container. The inspection device includes an ultraviolet light source which directs ultraviolet radiation onto an identifying mark on the container and causes fluorescent emmission of a narrow band of light. The radiation detection scheme of the present invention employs at least a pair of photodetectors, one which detects the very narrow band of radiation emitted from the fluorescent identifying mark, and the other which monitors whether or not any adjacent light bands are emitted from the object to a significant degree.Type: GrantFiled: March 4, 1980Date of Patent: February 23, 1982Assignee: The Coca-Cola CompanyInventors: Robert D.
