摘要:
The invention relates to a exchange system for filling machines which are provided with a system by which cylindrical carriers with an empty supply of zigzag folded tube foil can be replaced by a loaded carrier and that prevents that the filling unit during replacement is polluted or that any residue of the materials to be packed end up in the surroundings. These problems are prevented by making use of carriers with a loaded supply of tube foil that are mounted on the filling head. The exchange system comprises that the last piece of tube foil that was closed during the last filling, together with the elastic ring that was used, is wrapped in the first pack from the new supply of tube foil and can be removed without the filling head being exposed to the outside air.
摘要:
An annular container (20) mounted at the base of a passage between a layering tube (15) and a central mandrel (6) is charged with a layered tube of flexible tubing (22) delivered over a floating mandrel (5) when coaxially in contact with mandrel (6) by driving rollers (32) coacting with pinch rollers (48) on the floating mandrel (5). The tubing passes over the mandrel (6) and gathers in the layering tube (5) while being compacted by two sets of shoes (4, 4a) reciprocated 180° out of phase by rotating discs (53, 53a) and connecting rods. When sufficient tubing has been delivered the floating mandrel is raised to enable a hot wire to pass between the mandrels to sever the tubing (22). The layering tube (15) and central mandrel (6) with the container (20) can then be carried by a turntable (21) through further stationary positions where the layered tubing is further compressed by reciprocable rings, a lid is put on the container (20) to form a cassette and the cassette is discharged.

A spool (10) for storing film for a waste storage device includes a core (12) and a flared funnel portion (14). Film is stored on the core (12) and can be retained in place by shrink-wrapping (34) as a result of which the core can be formed without an outer wall or base, reducing material and moulding costs.

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.
摘要:
Maschine zum Füllen von schlauchförmigen, flexiblen Pakkungshüllen, insbesondere Wursthüllen, mit einem Füllrohr mit feststehender Längsachse, einer an das freie Füllrohrende sich anschließenden Verschließvorrichtung und einer in Betriebsstellung das freie Füllrohrende umgebenden Hüllbremse. Zum Aufführen eines neuen Hüllenvorrats auf das Füllrohr sind die Verschließvorrichtung sowie die Hüllbremse vom Füllrohrende entfernbar. Um die manuelle Einstellung der Hüllbremse zu vermeiden, sie zu schonen und eine automatische Betriebsweise zu ermöglichen, ist vorgesehen, daß die Bewegung der Hüllbremse, die sich aus einer Längs- und einer Schwenkbewegung zusammensetzt, zwangsläufig mit der Relativbewegung der Verschließvorrichtung zum Füllrohr gekoppelt ist.
