Patent number: 4356907Abstract: Elongate workpieces with enlarged heads to be distributed in groups to different destinations, such as plastic parisons to be delivered to respective mold cavities of a four-cavity blow-molding unit, are fed--partly by gravity--over a pair of sloping, counterrotating spindles to a tilted turntable, the spindles being separated by a gap letting the bodies of the workpieces hang down between them. The workpieces are successively inserted into peripheral recesses of the turntable along a raised edge thereof for rotary entrainment to respective guide channels confronting its opposite, depressed peripheral edge. Four workpieces at a time are dislodged from their recesses, after retraction of a barrier, by air jets driving them into the guide channels assigned to them. Fresh workpieces are deposited upon the upstream end of the spindle track by an elevating conveyor controlled by a monitoring device such as a photosensor which stops the conveyor upon detecting a backup of workpieces along the track.Type: GrantFiled: April 30, 1981Date of Patent: November 2, 1982Inventors: Samuel S.

Patent number: 4346881Abstract: Paper sheets are advanced seriatim between high speed upper and lower conveyor belts across a gap onto a slower speed multi-belt conveyor with which the upper high speed belts cooperate to form a sheet controlling tunnel. Static eliminating and sheet knock-down air is directed through the upper high speed belts and into the sheets traversing the gap. Advance of the sheets across the gap is facilitated by impermanent wave-like longitudinal stiffening rib deflection of the sheets where they leave the high speed conveyor belts. After each sheet has been fully received on the slow speed conveyor, its high speed travel is stopped by stop roll means to assure overlap of a succeeding sheet thereon. The stop roll means cooperate with the slower speed conveyor belts to effect impermanent wave-like longitudinal jam preventing stiffening rib deflection of the sheets.Type: GrantFiled: February 6, 1981Date of Patent: August 31, 1982Assignee: Lenox Machine Company, Inc.Inventor: Kenneth G. Frye

Patent number: 4345681Abstract: An elevator for farm produce or other articles includes a pair of continuous entrainments each having a series of spaced members, such as rods or rollers, supported by continuous bands. One entrainment is mounted within the other and the inner entrainment is slack over an ascending section so that it normally sags towards a corresponding section of the outer entrainments. When the entrainments are driven, material is picked up by the outer entrainment as it passes around inside a hopper. This travels up the ascending section whereby the slack section of the inner entrainment moves away from the corresponding section of the outer entrainment so that the material is elevated as a rising column. The inner entrainment takes up a natural spacing from the outer entrainment over the elevating sections. The lower end of the inner entrainment may form a converging inlet to assist initial elevation and its upper end may form a diverging outlet to assist in releasing the material at an outlet.Type: GrantFiled: September 17, 1980Date of Patent: August 24, 1982Inventor: Victor Vinson

Patent number: 4344521Abstract: Apparatus for conveying rod-like articles, especially cigarettes, includes parallel conveyors for streams of articles and two transfer conveyors which together re-orientate articles in one stream for combination with articles in the other stream. The transfer conveyors each convey articles on a curved path having a substantially vertical axis and include guide means for elevating the outer ends of the articles on the path. In another arrangement parallel opposed conveyors deliver articles to a downwardly-extending junction provided with retractable conveyor bands which may initially extend across the junction to aid filling. The stream on one of the opposed conveyors may be delivered from a further parallel conveyor by a rotary disc transfer conveyor which turns articles through 180 degrees for delivery to the one conveyor. The apparatus is particularly useful for tip-turning of cigarettes at the exit on a filter cigarette assembling machine.Type: GrantFiled: May 21, 1980Date of Patent: August 17, 1982Assignee: Molins LimitedInventors: David S. Bennett, Grantley R. Hoath

Patent number: 4343393Abstract: A hopper for feeding fruit in several transversely spaced lanes from a supply conveyor to the pick-up positions of a fruit feeder includes several drums mounted in spaced and downwardly inclined relationships. The spacing between the adjacent drums is adapted for the reception of a single file of fruit, and the inclination of the drums is sufficient to cause the fruit to gravitate downwardly to the feeder pick-up positions. A push-pull drive mechanism is provided to pivot the drums back and forth about their axes of rotation to cause the fruit to spin as they gravitate downwardly between the drums. Such spinning action facilitates rapid feeding of the fruit downwardly between the drums and, in particular, prevents irregularly shaped citrus fruit such as tangerines or lemsons from becoming enlodged against each other to thereby interrupt their flow to the pick-up positions.Type: GrantFiled: February 13, 1980Date of Patent: August 10, 1982Assignee: FMC CorporationInventor: Gregory J. Larsen

Patent number: 4340213Abstract: A photographic print stacking apparatus is positioned proximate the discharge end of a conveyor system which conveys photographic prints from a photographic print cutter. The print stacking apparatus includes upper and lower print receiving elements which receive and hold the prints as they are discharged. The conveyor system delivers the prints to the stacking apparatus with sufficient force to carry the prints between the upper and lower print receiving elements until their leading edges engage a generally upstanding stop element. A print deflecting flap element is connected to the upper print receiving element and extends toward the stop element. The print deflecting flap element prevents the leading edges of the prints from passing over the upper end of the stop element.Type: GrantFiled: December 10, 1979Date of Patent: July 20, 1982Assignee: Pako CorporationInventor: Gerald A. Jensen
