Abstract:
Apparatus is provided for each can filler unit (2) of a can filling machine comprising a support (44) for holding a liquid level controller (20) within a housing (4) of the can filler unit and control apparatus operated from outside of the housing for moving the support to position the liquid level controller at a proper position to ensure that each can is being accurately filled.
Abstract:
Apparatus for measuring the forces applied to a pull tab (18) during the formation of an opening in a container lid (6) having an upper and lower surface (10, 12) with a pull tab hingedly secured on the upper surface and a score line in the container lid defining an opening and wherein one container lid at a time is fed into a holder (20) having an opening (24) therein so that a substantial portion of the upper surface of the container lid and all of the pull tab are exposed. A load cell assembly having a pivotal hook member (38) is moved into position with the hook member between the upper surface of the container lid and the pull tab. The container lid is rotated about the axis of the hinge connection of the pull tab and the hook member is held at a fixed position. As the container lid rotates, the hook member applies resistant forces on the pull tab until the opening is formed in the container lid which resistant forces are measured.
Abstract:
A can bottom forming assembly (300) for forming the bottom wall (14') of a can body (10'). A bodymaker punch (320) urges a can bottom wall (14') first against an outer forming ring (330), then against a middle forming ring (336), and then against a domer die (342).
Abstract:
Apparatus for packaging a plurality of articles, such as ends (26) for beverage containers, using a plurality of accumulating cages (14, 16, 18) and a plurality of transfer cages (70, 72, 74) to feed an accumulated plurality of container ends in succession into a packaging station (8) wherein the accumulated plurality of container ends (26) are positioned between portions of a first continuous strip (200) of a flexible material permitting passage of at least a gaseous substance and a second continuous strip (188) having a thermally reactive surface facing the first continuous strip (200) and superposed portions of the first and second continuous strips surrounding the accumulated plurality of container ends (26) are sealed together to form interconnected plurality of sealed compartments (280) each having an accumulated plurality of container ends (26) confined therein.
Abstract:
Apparatus for forming can blanks into elongated can bodies comprising a support structure (4) having first and second gears (50, 58) rotatably mounted on the support structure and drive means (36) for rotating the first and second gears so that the second gear rotates in a direction opposite to the direction of rotation of the first gear. A redraw assembly (24) and can forming and ironing dies (22) located adjacent to the support structure. A ram (70) mounted on the support structure for reciprocating linear movement with portions thereof passing through the redraw assembly and the can forming and ironing dies. Connecting the ram to the first and second gears so that rotation of the first and second gears reciprocates the ram. In one embodiment, the ram does not rotate during the reciprocation thereof but in another embodiment the ram rotates during the reciprocation thereof.
Abstract:
A ductor roll assembly for transferring wet ink (112) from a rotating fountain roll (108) to a rotating distributor roll (130) within a wet ink transfer system for a can decorating apparatus having a main drive system (50, 55). The ductor roll assembly comprises at least one but preferably a plurality of ductor rolls (140) each movably mounted on a fixed support frame (102) for movement into a contacting relationship with either the fountain roll (108) or the distributor roll (130) to transfer the wet ink (112). Individual variable control units (186) independent of the main drive are provided for each of the ductor rolls (140) to move a desired number of them into contacting relationship with the rotating fountain roll (108) or the distributor roll (130) for any desired period of time so as to control the quantity and location of wet ink (112) transferred from the fountain roll (108) to the distributor roll (130) by the desired number of ductor rolls (140).
Abstract:
This invention relates to a self-generating pressure applying device to provide pressure on material within a container to dispense the material. A problem exists with the size and shape of some containers in association with the materials therein in dispensing all of the material. An expandable pouch (2) is provided, for applying a pressure to a material in a container so that it is dispensed, comprising two superposed sheets of gas and liquid impermeable material with the edge portions (8), (10) permanently sealed. A semi-permanent peelable strip (20) joins the two sheets to form one compartment and at least another compartment. The one compartment is divided into first (22), second (24) and third (26) sub-compartments by semi-permanent peelable strips (18). A first reactive component (30) of a chemical gas generating system is in the first sub-compartment and a second reactive component (32) in the third sub-compartment.
