  • Patent number: 5505312
    Abstract: First, second and third linear conveyors are arranged in alignment with each other in the stated order. Bottles to be inspected are conveyed standing on their bottoms on the first linear conveyor through an inspection station followed by an ejector for those bottles which fail to match specified characteristics of an acceptable bottle model. The second conveyor has spaced apart parallel translating conveyor belts for frictionally gripping the bottles by their bodies between them to make their mouth ends and bottoms clear for inspection. The bottle discharge end region of the first conveyor and the bottle inlet end region overlap to achieve an overall shorter machine. The second conveyor has a bottle discharge region that overlaps the bottle inlet end region of the third conveyor to achieve a shorter machine.

  • Patent number: 5499718
    Abstract: 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.

  • Patent number: 5466927
    Abstract: Apparatus for inspecting the bottom of a container that includes a light sensor positioned to view the container bottom through the open container mouth, a light source positioned externally of the container on the opposite side of the container bottom, and electronics for detecting commercial variations in the container bottom as a function of light energy incident on the sensor. The light source, as viewed by the sensor through the container bottom, is characterized by being elongated radially of the container bottom and narrow transversely of the container bottom. In this way, any variations in the container bottom that refract the line of sight of the sensor in the radial direction, such as mold code rings and baffle scars, are essentially transparent as viewed by the sensor.

  • Patent number: 5437702
    Abstract: A glass bottle production line comprising a bottle mold which has a plurality of mold cavities arranged in a predetermined order for forming bottles from glass parisons and for transferring the bottles to a conveyor in a predetermined sequence corresponding to the predetermined order of the mold cavities. The conveyor has a hot end portion and a cold end portion for receiving bottles from the bottle mold at an elevated temperature at the hot end portion and conveying the bottles to the cold end portion. A hot bottle inspector located at a fixed inspection station along the conveyor at the hot end portion non-touchingly inspects the bottles as the bottles are conveyed past the inspection station by the conveyor. A mold transfer signal and bottle detection signal are processed to determine the mold cavity used to produce the bottle detected at the inspector's station.

  • Patent number: 5414777
    Abstract: According to the process, each returning bottle is examined for the presence of a predetermined level of fatigue damage. If this level has been reached, the bottle concerned is marked with a mark enabling further trips of the bottle to be counted. When the count has reached a predetermined value, that is when the bottle has undergone the predetermined number of fillings, the bottle is removed upon its next return. It has been found that the life of the bottle can be anticipated with high accuracy in this way, thus enabling bottles to be withdrawn from circulation before failure occurs.

  • Patent number: 5412203
    Abstract: A cylindrical container inner surface tester which illuminates an opening of a test container. The test container is located at a predetermined position with its opening set levelly to capture the opening through a TV camera. The tester also detects black and white spots on the inner surface of the cylindrical container. This is accomplished by analyzing an image obtained by the TV camera using defect detecting means. The tester includes a frame memory which stores a multi-value continuous tone image signal as image data. The image signal is obtained by A/D-converting from a continuous tone image signal obtained by scanning the captured image. The tester also includes an area detecting unit which generates a binary image signal by binary-converting from a multi-value continuous tone image signal read by horizontally or vertically scanning the frame memory. This is accomplished using a predetermined threshold. The area detecting unit is also used to determine a test area.

  • Patent number: 5405015
    Abstract: A system for analyzing the physical condition of a moving article, such as a glass bottle, in a stream of articles of manufacture which are moving at a predetermined speed. A light source illuminates a portion of the moving article to be analyzed at an illumination angle, and a camera obtains an image of the illuminated portion of the article. The camera is disposed to view the article at a viewing angle that is distinct from the illumination angle, thereby substantially reducing the amount of reflected light received by the camera. A transparent surface is interposed between the camera and the article and angled to reduce the amount of reflected light received by the camera. A computer or the like processes the image to evaluate the physical condition of the article, and categorizes the article into distinct categories based upon the physical condition of the article.

  • Patent number: 5249034
    Abstract: A method of and an apparatus for inspecting an end of an object for a defect by which not only a defect caused by deformation of an end of an object in a horizontal direction but also another defect caused by deformation in a vertical direction can be detected with a high degree of accuracy. Light from an end portion of an object is received by a pair of one- or two-dimensional image sensors and disposed at a predetermined angle relative to each other, and brightness outputs of individual picture elements of the image sensors are stored into memories. From the stored signals, a bright line produced by light from an edge of the object end portion is detected for each image sensor, and a position of the bright line is calculated as a digital amount from a number of picture elements for each image sensor. Then, the digital amounts are added and substracted between the image sensors. A defect is judged from results of the addition and subtraction.

  • Patent number: 5072107
    Abstract: Photographs for detecting defects in the upper end face of the lip (43) of the mouth are taken by a camera (18) arranged on the axis of a bottle to be examined. An annular, coaxial light-conducting member (30), which is surrounded by a light source (28), is disposed between the lip (43) and the camera (18). It has a central viewing opening (40) with the shape of a double truncated cone (40a,40b). The generated surface of the truncated cone (40a) adjacent to the lip forms a light exit surface (46a) to illuminate the lip (43). The angle of slope of the truncated cone (40a) is selected so that an annular truncated cone of light (52) falls on the upper face of the lip (43) and has an angle of incidence of about 45.degree. in the middle thereof. This results in a dark-ground illumination of the lip (43). Should a defect be present in the region of the upper end face of the lip (43), this becomes visible as light on a dark background.
