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.

In the inspection of generally round glass containers where the containers are indexed into the gauging stations or positions by the movement of a starwheel mechanism, the containers are held in a generally upright attitude with their bottoms engaging a pair of spaced rollers extending through a slide plate at the gauging station. Each roller is biased in an upward direction against the container bottom. The containers are rotated, in station, by engagement of the sidewall thereof by a rotating wheel mounted on an axis that is somewhat out-of-vertical to aid in holding the container down against the rollers and slide plate. The gauging rollers each have their vertical movements drive the core of a separate differential transformer. The output of the transformers are amplified, alegebraically summed and fed to a discriminator. The tracking of the rollers is such that the output signals from the discriminator are a reflection of the relative positions of the rollers and the output is fed to a reject mechanism or indicator when a predetermined difference indicates that a "leaner" container is being gauged.

Indexing mechanism for multiple station glassware inspection machines in which a plurality of pocketed starwheels are used. One set of pockets are formed with container encircling or restraining members which open and close in response to the contour of a box cam. The encircling members loosely retain containers so that they may be rotated about their vertical axes while held in a specific location. The finish of the containers is guided by an upper starwheel having pockets of a size commensurate with the size of the finish of the container. The containers to be inspected are brought into the starwheel with the encircling members opened. Upon closing of the encircling members, containers may be indexed through a series of positions where they may be inspected for various defects. Prior to arriving at the position where the containers are to be taken from the starwheel, the containers are oriented with their generally long, horizontal axes normal to the direction of movement of the conveyor for taking containers away. This apparatus permits rotation of non-round containers while still retaining the containers in a sufficiently precise location so as to permit both mechanical and optical inspection of various portions of the container.

A finished product controller is disclosed for monitoring the performance of a glassware production line and the bottle inspection equipment operating thereon. Bottles are formed in molds which impress an identifying code unique to each mold in each formed bottle. Bottles leaving the forming machine are fed to one of several inspection loops. A primary inspection loop inlcudes apparatus for inspecting the bottles fed to it for defects and apparatus for reading the identifying code on those bottles. One or more secondary inspection loops are provided for inspecting the rest of the bottles for defects only. A computer correlates the detected defects in the bottles passing through the primary inspection loop to the defective mold which produced them and acquires defect data on the secondary loops. A cavity reject ratio is calculated for each defect and compared to a predetermined value to alert a forming operator to a defective cavity. The reject ratios are totaled for each defect and the ratio for each defect from each loop is compared to the corresponding ratio from the other loops to identify malfunctioning inspection devices. Located downstream of all of the inspection loops is an apparatus for reading the identifying codes of all the inspected bottles. In the alternative, the downstream reader can sense the presence of bottles formed in a particular mold which has been determined in the primary inspection loop to be defective, and the computer can alert maintenance personnel to locate and correct the defective inspection equipment in one of the secondary inspection loops.
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.

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.
摘要:
A multiple station inspection glassware inspection machine in which the containers are moved from station to station by engagement with a changeable, cylindrical pocket with a plurality of these pockets assembled to form an endless structure similar to a chain. Each of the semi-cylindrical pockets is adapted to engage the sidewall of the containers and to effect the indexing movement of the containers from an inlet where they are received from a conveyor and to carry the containers through a plurality of inspection stations. Various inspections may be carried out at the stations. Each container, after having moved through all of the stations, is returned to the conveyor. As each of the containers is moved through the series of positions while engaged in the pockets, they are retained in the posckets by the positioning of a guide rail system which effectively confines the bottles to the semi-cylindrical pocket of the indexing system. Details of the rail system, which is made up of a plurality of substantially identical rail supports spaced circumferentially about the pocketed indexing system, has unique configurations with regard to the actual bottle-engaging members which are provided on the holders or supports for the rails. Also illustrated, at one station, is a portion of the guide rail system which is provided with an opening within which a driven, bottle-engaging wheel is mounted to effect rotation of the bottle at this station.
摘要:
Apparatus is disclosed which provides an entrance gating structure for spacing the entry of containers carried by a conveyor into a testing device. The containers arrive at the testing device under line pressure and are then permitted to enter a testing apparatus where they are conveyed through the testing device and then returned to the conveyor. The gating device is a spring-loaded pivot arm having a pair of legs. One leg stops the flow of containers until the prior container clears the length of the long or other leg. The gate functions automatically without requiring any external operator.
摘要:
Apparatus, as set forth, in which glass containers moving on a horizontal conveyor in an upright attitude are guided into a bottle-engaging pocket, while the pocket is in position at an entrance position. The pocket is one of a series which are connected together in an endless series. An indexing hub supports a plurality of circumferentially spaced rollers about its periphery, with the rollers acting similar to a sprocket. The hub is indexed by a suitable drive. The rollers, in cooperation with the endless series of bottle-engaging pockets, will move containers held in the pockets through a series of positions at which the containers may be gauged or inspected for various defects. A second hub, which is essentially the same as the previously described hub, also has a series of rollers which engage the series of pockets. This second hub is mounted for "idler type" rotation about its vertical axis. Each of the series of bottle-engaging pockets have interchangeable inserts to accommodate different sized bottles, and the hubs actually support two vertically spaced series of bottle-engaging pockets.
