Definitions

  • rollers [52] US are mounted so that they extend inward] y and downwardly with respect to the container finish. With this arrangement and with the rollers spring-biased against e elevated container, rotation of the container about its vertical axis will maintain the container at a cific axial position relative to the in spespection system,
  • This invention is directed to the steadying and centering of glass containers during the period of inspection of the containers for optical defects in the finish of the container and also in the heel portion thereof.
  • the automatic inspection equipment where a plurality of containers are successively indexed through a series of inspection stations, one of the stations normally will be that station at which the container is inspected for vertical checks in the finish and radial checks in the heel.
  • the containers are raised upwardly by a generally horizontal pad having a diameter somewhat less than the diameter of the container, and the containers are then rotated by rotation of the pad.
  • FIG. 1 is a perspective view of the container centering and steadying apparatus of the invention shown in conjunction with a top vertical check detecting system;
  • FIG. 2 is a side elevational view of the apparatus-of FIG. 1;
  • FIG. 3 is a plan view of the hold-down roller apparatus of the invention.
  • FIG. 4 is a front elevational view of the hold-down apparatus illustrating the angle of the rollers.
  • FIGS. 1 and 2 the apparatus of the invention will be described in conjunction with a top vertical check detection system, it being understood that the optical inspection system illustrated is considered to be old in the art and is shown and described in U.S. Pat. No. 3,327,849, patented June 27, 1967.
  • a light source takes the form of a tubular, downwardly extending
  • the optical system is supported by a horizontal arm 14, which is adjustably clamped by the bifurcated member 15.
  • a screw 16 in the member 15 serves as the clamping or tightening arrangement with respect to the arm 14.
  • the bifurcated member 15, in turn, is supported on a vertical post 17.
  • the post 17, in turn, is mounted to a support member 18 fixed in position in opposition to the container indexing and handling system.
  • the container handling system takes the form of a pair of starwheels 19 and 20 which have cutout pockets within which the containers are positioned and moved or indexed into and out of inspection position.
  • FIGS. 1 and 2 show a container in theinspection position and, as can best be seen in FIG. 2, the base plate or supporting plate 21 is formed with an opening therethrough at the inspection station. This opening is normally occupied by a circular pad 22.
  • rollers 23 and 24 have provided a pair of rollers 23 and 24 which are contacted by the finish portion or neck portion of the container when the container is raised by the pad 22.
  • the rollers 23 and 24 have their axes at approximately 22 /2 with respect to the horizontal.
  • the roller 23 is carried or supported by an adjustable mounting fixture 25.
  • the roller 24 is carried by a similar fixture 26. Both of the fixtures 25 and 26 are bifurcated at their upper regions such that they may be adjustably supported on horozintal shafts 27 and 28 respectively.
  • the shafts 27 and 28 are joined at their inner ends by a yoke member 29 which leaves the central portion of the container,'at the inspection position, exposed to the light system. As viewed toward the right in FIG.
  • the yoke member 29 has a downwardly extending portion 30.
  • a horizontal opening extends through the portion 30 and another opening also extends through'a portion of the yoke member 29.
  • These two openings carry a pair of pins 31 and 32.
  • Both of the pins 31 and 32 extend from the yoke member 29 at one side thereof and the extending portion of pin 31 carries a generally horizontally extending arm 33.
  • the arm 33 is pivotally supported bya pin 34 carried by an upstanding lug 35.
  • the lug 35 also pivotally supports a pin 36 which extends through an arm 37.
  • Both the arms 33 and 37 extend generally parallel to each other with the arm 33 being vertically above the arm 37.
  • the rearward portion of the arm 33 carries an extension 38.
  • This extension 38 is provided with an undercut portion 39, which serves as the upper retaining seat for a helical spring 40.
  • the lower end of the spring 40 rests on the upper surface of the support member 18.
  • the helical spring as it will be readily appreciated, is under compression, and the position of the extension 38 relative to the support 18 is maintained by the force of the spring 40. Furthermore, when the bottle or container C is raised into inspection position, it will contact the rollers 23 and 24, causing the rollers 23 and 24 to raise with the only restraining force being the spring 40.
  • the upward position of the extension 38 of the arm 33 is limited by the position of a pair of locking nuts 41 on a threaded shaft 42 positioned coaxially with respect to the helical spring 40.
  • the locking nuts 41 will prevent the rollers 23 and 24 from dropping below the normal height of the container C as it is being brought into the inspection station.
  • the containers must be free to move into and out of the inspection station without interference, with the rollers 23 and 24 coming into play when the containers are raised by the pad 22.
  • rotation of the container by the pad 22 will maintain the container centrally with respect to the axis of the rotation pad 22. This, in turn, will assure the proper positioning of the container relative to the light source and the pickup or photodetector 13.
  • angle of the rollers has been stated as being 22- /z, it should be noted that this angle is not critical and was chosen as the steepest angle which would allow clearance for the optical system, with standard rollers when the smallest wide mouth jar is being inspected. The angle must be sufficient to give the centering effect to the container but not interfere with indexing of containers into and out of the station. It has been found that the angle range may be between 5 and 45 and perform when containers of various finish diameters are being inspected. For most containers of the widemouth style, the angle of the centering rollers will fall between 15 and 30.
  • Apparatus for steadying and centering glass containers during rotation about their vertical axes at an inspection station comprising, a pair of diametrically opposed, inwardly extending rollers, a pair of generally horizontal shafts joined by a yoke member mounting said rollers with their axes extending downwardly at an angle of between 5 and 45 with respect to the horizontal, means resiliently supporting said shafts by said yoke, said rollers adapted to engage opposed portions of the inside of the upper rim of the container being inspected to maintain the container in a particular position during rotation when the container and rollers are moved relative to each other at the inspection station.
  • said resilient mounting means comprises a pair of vertically spaced, generally horizontal bars pivotally connected to said yoke at one end and pivotally connected to a fixed mount at their opposite ends and means biasing one of said bars in a downward direction.
  • biasing means comprises a helical compression spring extending from said fixed mount to an extension of said one of said bars.
  • the apparatus of claim 3 further including means between said one bar and said'fixed mount for limiting the movement of said bar in one direction.
  • rollers are adjustably mounted on said shafts at equal distances from the center of said yoke.
  • rollers are positioned at about 22.5 with respect to the axis of said shafts.
