  • Patent number: 4332316
    Abstract: A takeoff-delivery mechanism for cup-like containers is provided with a pusher device that is operated repeatedly to remove stacks containing a predetermined number of containers from the front of a horizontal supply stack while containers are being fed to the rear thereof. Initially, each removed stack is fed to a horizontal delivery device which is then pivoted by moving its front end upward until the delivery device is generally vertical. The removed stack is discharged from the delivery device through the now downwardly facing rear thereof into a receiving device where the removed stack remains generally vertical.

  • Patent number: 4244460
    Abstract: A process and apparatus is described for the formation of a single row of regularly spaced discrete modules of thin products such as biscuits stacked face to face, from several rows of continuously moving products. As each row of products enters the apparatus, a module of products having a predetermined length is separated from the leading end of the row and is transferred into a pair of carrier fingers which supports the module of products. A module is formed at the end of each row in a timed sequence and the modules of products are then moved through a set of delivery channels by the carrier fingers into a common outlet channel.

  • Patent number: 4199050
    Abstract: An apparatus for the packaging of comestibles and other materials in individual cup-shaped containers has a cup-discharge station at the end of a conveyor at which the filled cups are removed from respective receptacles in the conveyor. Individual lifting plates below the conveyor raise the cups into an array of grippers which are relatively displaceable in two mutually perpendicular directions so that, when the array is displaced from alignment with the lifter plates, the inter-cup spacing can be reduced.

  • Patent number: 4193784
    Abstract: Glass containers received on a machine conveyor which passes a plurality of forming machine sections and receives the ware from the sections is coordinated in its relationship to the machine sweepouts, such that a gap is provided periodically in the row of ware carried by the machine conveyor. A bottle-transfer device which transfers the ware from the machine conveyor to a cross-conveyor is operated so that it also will maintain the gap that is provided in the line of ware. The ware on the cross-conveyor moves in line across the open-receiving end of the lehr and is pushed from the cross-conveyor onto the moving lehr mat. By providing a gap in the line of ware, the lehr loader pusher bar may be operated more slowly than in the past and to thereby provide a more stable transfer of ware from the cross-conveyor to the lehr.

  • Patent number: 4141442
    Abstract: A continuous column of articles, which are individually non-uniform in weight, is divided into a series of column segments each of which has a uniform predetermined weight. The articles in the continuous column are fed by an infeed conveyor onto an intermediate conveyor one at a time. The belt of the intermediate conveyor is carried by the platform of a scale so that the cumulative weight of the articles on the intermediate conveyor is monitored. When the weight reaches a predetermined value, a pusher is activated to push the group onto an outflow conveyor which is parallel to the intermediate conveyor and is driven in the opposite direction.

    Abstract: A method and apparatus are disclosed for precision placement of a workpiece onto a transport member. A plurality of workpieces are aligned in a predetermined spacial relationship upon an infeed conveyor. The workpieces are then moved transversely off the conveyor and dropped through a pair of counter-rotating lubricating rollers. An arcuate chute directs the workpieces from the lubricating rollers to a horizontally disposed planar surface where they are realigned by a cooperating scraper positioned intimately above. Relative movement between the scraper and the planar surface causes the workpieces to be discharged from the surface and precisely deposited upon the transport member.

  • Patent number: 4039072
    Abstract: A system for conveying molded bricks known as briquettes from a press to a bed plate wherein the briquettes are each conveyed by a plurality of spaced parallel belts to above a conveyor which carries the bed plates under the briquettes supported by the conveyor belts. An inclined substantially coplanar conveyance track which includes elongated rollers has its after portion periodically raised whereby the rollers located in the after portion penetrate upwardly between the belts carrying the briquettes thus lifting the briquettes from the belt. A removal mechanism pushes the briquettes down the rollers of the conveyance track onto a removal plate which pivots with the conveyance track and extends therefrom at a slight incline, the briquettes being received by the main conveyor carrying the bed plates whereby the briquettes are pushed over the conveyance track and onto the bed plate.

  • Patent number: 4022333
    Abstract: Switches in an electrical control circuit are disposed in the path of bales being loaded by a pair of conveyors, and these switches control the operation of the conveyors such that bales are loaded on a platform and selectively positioned with the leading end of a first bale flush with one end of the platform and the trailing end of a following bale flush with the other end of the platform. Relays and a solenoid-operated valve are also utilized in the electrical control circuit to control operation of the conveyors as well as a pusher mechanism that moves bales in a row laterally when a row has been loaded with their opposite ends flush with the ends of the platform. Since the ends of the bales are flush with the ends of the platform, a stack of bales can be formed with even ends.

    Abstract: An improved lehr loading bar for loading newly formed glass containers into an annealing lehr. A series of relatively flat faced liner bars are loaded into a carrier bar having opposed dove tail slides. The liner bars are separated by spacers which also engage the dove tail slides. The space between adjacent spacers defines a pocket into which a glass container may fit for transfer to a lehr. Both liner bars and spacers are made of carbon or carbon graphite material to prevent thermal damage to the hot glass containers when they touch them.

  • Patent number: 3978970
    Abstract: A live roll conveyor receives randomly supplied upstanding containers, such as cans, and arrests the leading cans with a pattern stop bar having pockets that arrange a transverse row of cans to receive a next assembled row of cans in nesting relation. When a backlog of alternately offset rows of cans extends upstream of an overhead clamp spaced from the pattern bar, the clamp locks two rows of containers to hold back the further upstream containers, and the pattern stop moves downstream so that one assembled charge of nested containers is moved unitarily downstream by the live rolls. A separator or retaining plate with downturned edge flanges is placed on the charge of cans, the pattern stop is further retracted to expose an underlying guide bar and allow the charge to seat against the guide bar, a gate is lowered to allow lateral discharge of the charge of cans, and a sweep arm pushes the charge to a laterally adjacent container basket of a containerized cooker.
