55557082, Sep 17, 1996

Filed:

Apr 21, 1995

Appl. No.:

8/426105

Inventors:

Michael F. Shower - Waterford MI
Kenneth P. McDonald - Wixom MI
Anthony J. Lukasiewicz - Howell MI

Assignee:

Elopak Systems A.G. - Glattbrugg

International Classification:

B65B 102

US Classification:

53563

Abstract:

A pressure sealing mechanism having a yoke into which a mandrel is positioned while having a carton tube mounted thereon with overlapped end closure panels, the yoke including side walls, a closed outer end wall, oppositely disposed, inwardly extending flanges formed on the inner ends of the side walls, with cooperating slots formed in the mandrel, and an expansible bladder and a pressure pad mounted in the yoke for sealing the panels upon expansion of the bladder by forcing the yoke radially outwardly such that the flanges engage the slots providing a compressive force on the panels.

Assignee:

International Classification:

B65B 300

US Classification:

1983462

Abstract:

A container lifting arrangement wherein a pair of spaced rails and a vacuum cup assembly are concentrically mounted and relatively actuated to raise and lower a container, in part while the container is being conveyed toward a filling station by a conveyor. The vacuum cup is caused to engage the bottom surface of the container only after the container's forward movement has been stopped so as to not be subjected to any sliding action by the container, such action tending to roll the cup's edge and destroy its suction capabilities. Lifting the container before the conveyor stops provides additional time for filling the container.

Filed:

Oct 14, 1988

Appl. No.:

7/257845

Inventors:

Badruddin K. Rangwala - Farmington Hills MI
Kenneth P. McDonald - Livonia MI

Assignee:

Elopak Systems A.G. - Glattbrug

International Classification:

B67C 320
B67D 530

US Classification:

141 9

Abstract:

A container filling system on an indexing, forming, filling and sealing machine, wherein each successive container is progressively filled with variable volumes of a fluid, such as milk, in a manner which minimizes the foam build-up therein, thereby enhancing leak-proof top sealing characteristics during high production operations. The containers are filled in accordance with the following filling sequence formula: ##EQU1## wherein: V. sub. t =total carton volume V. sub. i =volume delivered at i station i=station number n=number of stations.

Appl. No.:

6/851173

Inventors:

Badruddin K. Rangwala - Farmington Hills MI
Kenneth P. McDonald - Livonia MI

Assignee:

Ex-Cell-O Corporation - Walled Lake MI

International Classification:

F16K 336

US Classification:

137241

Abstract:

A filler sterilization system including an inlet valve, a main valve, an outlet valve, a linkage system therebetween and a cam and follower arrangement for actuating the linkage system to move the three valves into three operating positions. The three positions are the normally closed and open positions for dispensing a liquid product into a carton, and a third position for steam sterilization of the filler system. The outlet valve in the latter position is such that a predetermined back pressure is maintained during the sterilization operation.

Appl. No.:

9/102782

Inventors:

Barry C. Owen - Troy MI
John A. Weber - Webberville MI
Timothy H. Drury - Howell MI
Kenneth P. McDonald - Wixom MI

Assignee:

Elopak Systems AG - Glattbrugg

International Classification:

B65G 2300

US Classification:

1988321

Abstract:

A machine including a single power source for asynchronously operating dual indexing conveyors. The single power source is a reversible servo unit operatively connected to gear sets and one-way clutches to drive the conveyors. Alternately, the power source is a uni-directional rotating driver with linkage means to reciprocally move a rack operatively connected to gear sets with one-way clutches or ratchets and pawls.
