  • Patent number: 7861496
    Abstract: An article packaging machine includes a trailing article pusher assembly for pushing the trailing articles of a packaging production run down infeed conveyer lanes and through workstations of the packaging machine so that the trailing articles can be packaged. The pusher assembly comprises a pusher chain that is flexible in one direction to allow the chain to be coiled upon itself and generally inflexible in the other direction beyond a substantially straight configuration of the chain. A pusher block is attached to a free end of the pusher chain. The pusher chain is normally stowed on a take-up magazine beside its associated infeed lane during a packaging operation. When the trailing articles of a production run approach the workstations of the packaging machine, a gate opens to allow the pusher chain and its pusher block to be extended into the infeed lane behind the last trailing article.

  • Patent number: 7191580
    Abstract: An apparatus for depositing a filament tow in a stationary can. To this end, the filament tow is conveyed to the can by a conveyance means which includes a pair of driven reels. For deposition into the can, the filament tow is guided in such a way that the feed position of the filament tow in the can constantly changes. To allow the filament tow to be deposited with a high filling density, for deposition into the can the filament tow is guided by two separate oscillating motions of the conveyance means during conveying which are transverse to the conveyance direction. In this manner, undesired reactions on the filament tow are advantageously avoided during deposition.

  • Patent number: 6049957
    Abstract: A method and apparatus for filling a shell body with sub-projectiles in a predefined geometric arrangement and in a very short time without creating shifting errors is provided. Prior to filling the shell body, the sub-projectiles may be combined into layers which are as thick as the length of the sub-projectiles and which extend in planes transverse to a longitudinal axis of the shell body. The sub-projectiles take up a position in the layer which corresponds to their geometric arrangement in a hollow chamber of the shell body. During the combination, the outer periphery of the layers may be shaped so that, following insertion of the layer into the hollow chamber, the sub-projectiles may be held there and fixed against relative rotation while maintaining the previously formed geometric arrangement. In accordance with a preferred embodiment, the outer periphery of the layers may assume a hexagonal shape where the axes of the cylindrical sub-projectiles are aligned with the longitudinal axis of the shell body.

  • Patent number: 6003286
    Abstract: An automated packaging system that can simultaneously process a single case or a plurality of cases and can be adjusted to accommodate packages and cases of various sizes. Individual packages are fed to the packaging system on the package conveyor. The packages are recognized by the system when they energize an electric eye which causes the package to be elevated above the conveying surface of the package conveyor and stopped below a pick and place mechanism. The individual packages are elevated by plates having upper surfaces that extend through slots in the conveying surface and are stopped by vacuum cups carried by the upper surfaces of the plates. The upper surfaces of the plates are inclined which causes the packages to climb the incline which functions to decelerate the movement of the package.

    Abstract: A lettuce head holding tray is defined in which both the upper tray layer and the lower tray layer are packed side-by-side at packing stations. At a carton loading station, two side-by-side arrays of plungers each are used for packing of discrete layers of the cartons. One array of plungers packs the bottom carton layer; the other array of plungers packs the top carton layer. Two cartons are disposed opened upwardly to the plunger array at the packing station; one carton is disposed to the bottom layer loading plunger array for packing of the bottom layer and the other carton--with its bottom layer previously packed--is disposed to the top layer loanding plunger array for packing of its top layer. The cartons--between the packing of the bottom layer and the packing of the top layer--are conveyed between positions underlying the plunger arrays. Thus each carton has is lower layer packed by the lower layer loading plunger array and then its top layer packed by the upper layer loading plunger array.

  • Patent number: 5039276
    Abstract: The grouping of objects, for example unit packaging goods, is accomplished by automatically assembling a stepped formation of the goods and subsequently leveling-off the stepped formation. To accomplish the foregoing, a serially increasing number of the goods are delivered in steps to a grouping station until a maximum number is reached and thereafter the number of goods per step is serially decreased. By exercising simultaneous control over the in-feed of goods and the shifting of the goods step-wise in a direction transverse to the in-feed direction after each delivery, finished groups having a predetermined size and configuration are formed at a downstream end of the grouping station and these finished groups are shifted out of the grouping station in the in-feed direction in synchronism with the in-feed of goods as the number of goods per step being fed in decreases.

    Abstract: An automatic packaging machine includes a loading station for simultaneously and sequentially picking up a plurality of elongated products and deposing them in a spaced parallel alignment within a box. At the time of loading each of the products has an initial volume which is substantially greater than the volume which the same product will have after it has settled over time within the box. Thus, the box id overfilled by an amount which will make it full after the products have settled. Then, the overfilled box is advanced to a closing station, where the lid is closed over the filled box without damage to the products. This immediately reduces the volume of the products to the volume which they would have after they have settled.

The articles are delivered to an inclined conveyor which has a lower end adjacent to a horizontal conveyor with a stop roller being positioned between the conveyors. When the articles have collected on the inclined conveyor a predetermined distance up the incline, a drive is actuated which simultaneously moves the inclined conveyor upwardly and moves the horizontal conveyor away from the inclined conveyor while rotating the stop roller to permit the articles to move from the inclined conveyor to the horizontal conveyor. This conveyor motion causes the articles to gently cascade down the incline in spread out fashion so that they are transported toward the end of the horizontal conveyor remote from the inclined conveyor and across the entire breadth thereof.

    Abstract: An arrangement for the feeding of objects to and grouping them on a base.In order to simplify handling and transport of milk packages it is frequent to use transport packages in the form of trays or the like, onto which a number of milk packages are placed in close stacking. For this purpose automatic machinery is used, which machinery automatically loads the milk packages on a transport package placed in position for loading. In order to avoid interruptions when an empty transport package has to be substituted for a filled one this invention suggests an arrangement according to which the milk packages are first collected in close stacking on a pre-loading surface. Thereafter, when the new transport package has been brought in correct position adjacent to the pre-loading surface, the collected milk packages are transferred onto the transport package.
