Abstract:
The subject invention relates to a vacuum wand assembly (10) for extracting a product (12) from a container (14), especially a non-self supporting container that collapses as the product is extracted. The assembly (10) includes a wand for extending into the container (14) and for withdrawing the product (12) therefrom. A vacuum source (18) is connected to the wand (16) for applying a vacuum to extract the product through the wand (16). A supporting structure (24) supports the wand (16) and is moveable relative to the container (14) for carrying the wand (16) as the product (12) is extracted from the container (14). The wand (16) is limited in a vertical direction by the supporting structure (24). This keeps the wand (16) at the pre-determined level relative to the product within the container (14).
Abstract:
Apparatus including a conveying member defining a loop (98). The conveying member can be a belt, a chain, or plurality of hinged plates. The invention also includes first and second supporting members (92, 94) individually disposed at opposite sides of the loop and spaced a first distance apart from one another. The first and second supporting members support rotating movement of the conveying member. A moving device (102) is operable to translate the first and second supporting members concurrently along a path having at least one bend (106). The lengths of the portions of the conveying member disposed on opposite sides of the bend can be adjusted by the moving device. A bendable frame assembly (108), connected to the moving device, extends between and is attached to the first and second supporting members.
Abstract:
The invention provides a diameter reducing system for reducing the diameter of a flexible container (12) as the container is filled. The system includes a stretching device (24) to stretch the container at the fill level as the container is filled with a plurality of particles. The stretching device can release a stretched portion (22) of the container substantially at the fill level as the fill level rises. The container can be a flexible, elastic bag. Shrinking of the container at the fill level as the container fills promotes supporting engagement between particles to enhance the structural integrity of the filled container and to reduce the likelihood that particles will be damaged during movement of the filled container.
