  • Patent number: 6773385
    Abstract: Methods and apparatuses for inserting flexible bags and other liners into open packaging containers. One or more engagement heads engage and position the flexible liners in preparation for their insertion into open containers using an insertion assembly. One or more of the engagement heads are preferably made with vacuum heads that are movable to open the liner for the insertion assembly. A cuffing assembly can be included for cuffing the open end of the liners over the top edges of the open containers. Clamping assemblies can be included on the cuffing assembly to facilitate holding the liners during insertion and cuffing. The use of an engagement assembly, insertion assembly, and cuffing assembly which are independently driven helps to provide greater speed and operational flexibility.

  • Patent number: 6767316
    Abstract: Methods and apparatuses for inserting flexible bags into open containers, and cuffing an open end of the flexible bags about a top edge of the open containers. The method and apparatus include a vacuum assembly having at least one movable vacuum head for engaging and positioning the flexible bags in preparation for their insertion into the open containers. An insertion assembly having a mandrel inserts the flexible bags into the open containers. A cuffing assembly can be included for cuffing the open end of the flexible bags over the top edges of the open containers. The vacuum assembly may engage a flexible bag from a bag dispenser while the mandrel is in an extended position within the container. The method and apparatus also facilitate the use of a vacuum assembly, insertion assembly, and cuffing assembly which are independently driven to provide greater speed and flexibility to the bag opening, insertion and cuffing processes.

  • Publication number: 20030166442
    Abstract: Methods and apparatuses for vacuum engagement of flexible bags and other liners, such as for insertion into and cuffing upon packaging containers. The vacuum engagement heads are preferably made with vacuum relief ports and slotted apertures having a reticulated material therein to prevent the flexible film liners from filling the heads. The heads may be presented in opposing pairs that are misaligned to facilitate separation of opposing leaves. Also disclosed are grippers that may bear upon the liners to help in separating the liners from a dispenser. Further disclosed are inserting, cuffing, and clamping assemblies used in an insertion and cuffing apparatus that uses independent operation for greater operational flexibility and speed.
