Patent number: 5651511Abstract: A machine for feeding rolls of web material to a utilization device that is adapted to draw the web material into the utilization device. The roll machine includes a frame carrying a carriage that supports a pair of arms having respective chucks that are adapted to move toward and away from each other for engaging and disengaging with the core of a roll that is being supported and fed. An overhead drive arrangement is used for driving the periphery of the roll in combination with a torque roller for maintaining tension in the web. A gravity loop of the material has its position sensed for control of the roll drive means in a manner to match the rate of use by the utilization device. The drive arrangement may also include a motor that directly drives the roll core. The chucks driving the roll core may further be adaptable to variably support various roll core diameters and may include structures for positively gripping the core.Type: GrantFiled: June 7, 1995Date of Patent: July 29, 1997Assignee: Roll Systems, Inc.Inventors: H.

Patent number: 4921132Abstract: A system for monitoring ink flow from an ink storage tank to at least one ink fountain of a high-speed, web-fed printing press employing a scale for measuring the weight of the ink storage tank and comparing weight signals from the scale at successive times to determine the weight of ink consumed over the interval between readings. A pump is associated with the storage tank for pumping the ink to the fountain via coupling lines. An ink level sensor detects the level of ink in the fountain and provides an ink demand signal for operating a value means in the ink coupling line to in turn cause ink flow to the fountain so as to provide replenishment of ink thereat. With the use of plural fountains, means are provided for prioritizing delivery to the fountains so that individual ink comsumption on a per fountain basis can be determined. In this regard, the system also employs a volume sensor preferably in the form of a pump stroke positon sensor for determining incremental weight delivery per stroke.Type: GrantFiled: July 20, 1988Date of Patent: May 1, 1990Assignee: Automation, Inc.Inventors: R.

Patent number: 4736680Abstract: A closed loop register control system used in association with a printing press and comprising a television camera in combination with a strobe light and a solid state imaging device which enables continuous scanning of the sheet web. The apparatus of this invention also comprises a printing press console having associated therewith a digitizing tablet and a television monitor. The location of the area that is to be examined is defined by the pressman. The area to be examined may be selected by laying a proof sheet down on the digitizing tablet and recording the coordinates of the area of interest. This controls the camera and strobe light with the pressman selecting one part of the image as important and causing the register mechanism to maintain register in that selected area. Electronics then make comparisons between the detected image and a desired reference image to cause correction on a per color basis at the printing press stations.Type: GrantFiled: December 18, 1985Date of Patent: April 12, 1988Assignee: Web Printing Controls Co.Inventors: R.

Patent number: 4605083Abstract: A method and apparatus for separately weighing, by means of a common scale, contributions of material from multiple streams, such materials typically being printed papers, such as from a printing press. Material that is to be weighed, which is typically waste material, is loaded into receptacles or the like for temporary storage thereof and is subsequently and sequentially released into a storage bin or the like associated with the common scale. An increase in measured weight associated with each respective material release or discharge is then determined. From each weight increment associated with one of the multiple streams, is added to provide a total count corresponding to weight and associated with each, one of the individual streams of the multiple streams of material. In this way, separate count totals are maintained and continuously updated for a plurality of different corresponding deliveries but using a common scale and associated storage bin or container.Type: GrantFiled: December 13, 1982Date of Patent: August 12, 1986Assignee: Automation, Inc.Inventors: R.

Patent number: 4602692Abstract: A method and apparatus for separately weighing, by means of a common scale, contributions of material for multiple streams, such material typically being printed papers, such as from a printing press. Material that is to be weighed, which is typically waste material, is delivered by workers or operators along multiple respective routes to the common scale bin. Means are provided which are worker initiated, to provide enabling signals respectively associated with the multiple routes along with means responsive to these enabling signals while providing a plurality of separate counts corresponding to weight for each respective route. Delivery of material along each route may be detected by, for example, a floor mat switch, a actuated push button, or by photo detector means.Type: GrantFiled: October 9, 1984Date of Patent: July 29, 1986Assignee: Automation, Inc.Inventors: R.
