摘要:
Apparatus for inspecting glass containers in which an indexing starwheel moves a plurality of containers in series through a plurality of positions or stations where the containers are physically and optically examined.One station, or position, is described in detail as the position where a glass container that is in a vertical position is rotated about its vertical axis by engagement of the finish thereof with a driven wheel. Rotating worm means move the bottles into and out of the handling system and serve as means to time the bottle movements. A mechanism at the exit position assists the bottles out of the starwheel. At the station where the sidewall of the bottles is to be inspected, a light source in the form of a tall housing is positioned in a vertical, annular recess of the starwheel. Additionally, the starwheel is made such that individual containers are contacted by rollers supported from the starwheel and at the sidewall inspection station the container is held in the starwheel, in engagement with the lower rollers, by a side-engaging biased roller. The manner of holding and rotating the bottle is such that a vertical sidewall section of the container is unobstructed, both from the viewpoint of outwardly directed illumination, and view by a camera positioned radially outward of the container.

There is described a plug and air warp gauge which takes the form of an elongated vertically, reciprocated gauging head that is mechanically driven under the influence of a rotating cam. Coaxially within an annular head is positioned a plug which has a diameter such that it will pass through an unchoked neck of a bottle. The plug is attached to the lower end of a tube which is coaxially positioned within a larger tube. The larger tube is raised and lowered mechanically and when in its uppermost position, will support the plug-carrying tube. When the larger tube is lowered, the plug tube also is lowered. The lower end of the larger tube is in the form of an annular piston which will move downward within a cylinder that seats on the bottle finish. As the annular piston moves down, it will pressurize the inside of the bottle and the cylinder if the seal with the finish of the bottle is good. After the arrival of the larger tube at its lowest position, both the pressure generated in the bottle and cylinder and the position of the plug tube are observed for determining the presence or absence of a defective bottle.

Apparatus for inspecting glass containers in which an indexing starwheel moves a plurality of containers in series through a plurality of positions or stations where the containers are physically and optically examined.One station, or position, is described in detail as the position where a glass container that is in a vertical position is rotated about its vertical axis by engagement of the finish thereof with a driven wheel. The container, as it is rotated, is viewed by a camera whose lens focuses the sidewall image of the bottle onto a vertical, linear array of light sensitive pick-ups in the camera. The camera is supported relative to the bottle handling system for adjustment up and down, back and forth and sideways so as to have the flexibility of viewing different size bottles. At the station where the sidewall of the bottles is to be inspected, a light source in the form of a tall housing is positioned in a vertical, annular recess of the starwheel. The light source is composed of three columns of five lamps plus a diffusion plate, with the outer columns being lit when viewing flint bottles and the center column is additionally lit when amber bottles are being viewed. The circuit for the lamps is provided with a means to detect the presence of burned out bulbs.
摘要:
In a cavity identification system the containers, which are upright, will be in single file and will be diverted from a linear conveyor by a rotating starwheel, having in the periphery thereof, pockets which generally correspond to the external diameter of the containers. The starwheel serves to guide the containers from the side of the conveyor, in slightly spaced-apart fashion, over an identification station where the cavity identification reader is positioned. After the container has passed the reading position, it will be moved back onto the moving conveyor so that the container will be carried to a later processing position. Guard rails are provided at both the incoming and outgoing ends of the cavity reading system to guide the containers in series relationship. The described inspection apparatus may be moved as a unit away from the side of the conveyor an amount to clear the normal span of the conveyor. When the inspection apparatus is moved away, a pair of straight rails will be automatically moved into the intervening gap in the permanent guard rails over that span of the conveyor which is bypassed for inspection purposes. The straight rails then span the gap between the permanent rails that are already present in overlying relationship to the conveyor, and in this manner the containers which are being moved by the conveyor may move uninterrupted during any period when the identification or inspection equipment is temporarily out of use.
