Filed:

May 24, 2010

Appl. No.:

12/785814

Inventors:

Charles M. Hirtreiter - Park Falls WI, US
John R. Sofinowski - Jarrettsville MD, US
James A. Cummings - Phillips WI, US

Assignee:

Marquip, LLC - Phillips WI

International Classification:

B32B 41/00

US Classification:

156 64, 156210, 156292

Abstract:

A method for automatically setting the rider roll/glue applicator roll gap for the single face web on a glue machine senses a forward drag that the single face web, operating at corrugator speed, exerts on the glue applicator roll, driven at an underspeed, after bringing the flute tips of the single face web into contact with the glue applicator roll by adjusting the position of the rider roll. Changes in forward drag exerted on the glue applicator roll are monitored and related directly to glue applicator roll drive current to provide a slight compression of the single face web between the rider roll and the glue applicator roll. Preferably, the glue applicator roll uses a regenerative drive and the target drive current command in a feedback control system to cause the gap to be adjusted to achieve the desired slight compression of the web flutes and to maintain the glue applicator roll under speed.

Appl. No.:

7/116824

Inventors:

John R. Sofinowski - Glen Arm MD

Assignee:

United Container Machinery Group, Inc. - Glen Arm MD

International Classification:

B25B 2302
B25B 2304
B25B 2306

US Classification:

81 5737

Abstract:

A robotic die mounting mechanism can be used to apply or remove fasteners to or from aligned locations such as pre-drilled and pre-tapped holes in a cutting die and backing drum for attaching or detaching the die to or from the drum. The mounting mechanism including a fastener supply magazine with a dispensing chute, a robotic arm, a socket on a rotary driver, and an actuator mounting the driver. The magazine holds a supply of the fasteners and its chute dispenses one fastener at a time from the magazine. The robotic arm movable between a fastener pickup position adjacent the magazine chute and a fastener discharge position remote therefrom and above the die and drum receives one fastener at a time from the magazine chute and transfers the fastener from the fastener pickup position to the fastener discharge position. The socket on the rotary driver engages the fastener at the fastener discharge position. Upon actuation of the actuator, the rotary drill and the socket therewith are moved to advance the fastener from the fastener discharge position to a fastener applying position adjacent to the die and drum.

International Classification:

Abstract:

A method for minimizing cross-machine direction variations in temperature and moisture content of a web running through a corrugator single facer. The method includes running the web through a web preheater station of the single facer and capturing an image representing an actual temperature of the web downstream of the preheater station in the cross-machine direction with a thermal imaging device. The method includes sending the image to a programmed process controller that applies thermal pattern recognition to the image and determining with the controller if the actual temperature of the web deviates from a desired temperature range. The method also includes determining with the controller a corrective action that will bring the actual temperature of the web within the desired temperature range and generating and sending a control signal with the controller to vary an operating condition of the preheater station so as to bring about the corrective action.
