  • Patent number: 4401205
    Abstract: A tobacco shredding machine wherein an upright duct delivers particles of tobacco to the rear portion of a channel wherein the particles are converted into a continuous cake whose front end is severed by a set of orbiting knives. The lower rear portion of the duct contains a deflecting conveyor which diverts the oncoming tobacco particles from a vertical path into a horizontal path and drives the oncoming particles at a speed which is a multiple of the speed of tobacco compacting conveyors flanking the channel. The speed of the deflecting conveyor is changed in response to changes in the height of the opening between the stationary and movable sections of a mouthpiece through which the cake passes on its way into the range of the oribiting knives. This ensures that the height of the opening reassumes its normal value without changing the speed of the compacting conveyors. The deflecting conveyor is installed in a support which is removably insertable between the side walls of the duct.

  • Patent number: 4235248
    Abstract: A distributor wherein a belt conveyor transfers batches of tobacco particles from a main magazine into a wide upright duct. The level of different portions of the upper surface of the supply of tobacco in the duct is monitored by several photosensitive detectors which transmit signals for adjustment of a paddle wheel which removes surplus tobacco from the transfer conveyor by brushing off more or less tobacco from different portions of the conveyor, as considered transversely of the direction of movement of the conveyor, in order to maintain the entire upper surface of the tobacco supply in or close to a horizontal plane.

  • Patent number: 4223778
    Abstract: A parison handling assembly receives tubular plastic parisons from a random bulk storage, orients the parisons, and feeds the parisons in a controlled manner to one or more blow molding machines. Parisons are stored in the random bulk storage and fed at a controlled rate by a metering apparatus to a parison orienter which orients the parisons into a closely grouped arrangement wherein the parisons are both upright and side-by-side. The parisons are fed from the parison orienter to a parison escapement mechanism which holds the parisons temporarily. The escapement mechanism is actuated to release parisons into a parison transporter depending on the production demands of the individual blow-molding machines. Released parisons, from the parison escapement mechanism, move along the parison transporter to be pushed axially into stuffer tubes. The stuffer tubes hold the parisons in properly oriented, end-to-end relationship for delivery to the actual loading station of the blow-molding machine.

  • Patent number: 4223845
    Abstract: A tobacco shredding apparatus wherein a relatively small upright duct receives tobacco from a large magazine. A system of tobacco compacting chains draws tobacco from the lower part of the duct and feeds the resulting cake into the path of orbiting shredding knives. The chains and the knives are driven by a first variable-speed motor. A conveyor which is driven by a second variable-speed motor transfers tobacco from the magazine into the duct. The volume of tobacco in the duct is monitored by a first set of photocells whose signals are used to regulate the speed of the second motor so as to maintain the volume of tobacco in the duct within a first range. The volume of tobacco in the magazine is monitored by a second set of photocells whose signals are utilized to regulate the speed of the first motor so as to maintain the volume of tobacco in the magazine within a second range. The capacity of the magazine is between five and ten times the capacity of the duct.

  • Patent number: 4202438
    Abstract: This discloses a system for lifting or conveying granular, pulverized or fluid material from a first location to a second location. A long flexible tube, open at the ends, encloses a highly flexible rotary driven helical coil spring equipped at parallel, spaced-apart positions along its length with a plurality of attachments, called "portable flights", which may comprise a shallow cylindrical cup formed from a pair of semicircular plates. The cups are secured to a succession of rungs in angularly staggered relation along the length of the helical spring, and serve to pick up and convey a substantial quantity of the pulverized, granular or fluid material from an input container, in which the tube is immersed, to a product chute near the top of the tube leading into a collection hopper.

  • Patent number: 4172515
    Abstract: The moving parts of a tobacco cutting machine and the conveyor or conveyors which transfer tobacco to the cutting machine are driven by a variable speed motor whose speed is regulated in dependency on the volume of tobacco in a duct from which the conveyor or conveyors draw or receive tobacco for transfer into the machine. The height of the pile of tobacco in the duct is monitored by photoelectric cells which transmit signals to a speed regulator for the motor so that the speed of the motor increases and decreases when the height of the pile respectively increases and decreases. The duct receives tobacco from a magazine. Fluctuations of the height of tobacco pile in the duct are due to variations in the rate of tobacco feed from the magazine and/or to changes in size, moisture content and/or temperature of tobacco which is being supplied to the duct.

  • Patent number: 4149622
    Abstract: A device is described for capturing certain predetermined types of mail pieces from a moving mail flow and for regulating the subsequent delivery thereof to processing equipment. The device is comprised of a receiving station and a delivery station linked by a common narrow transport. The latter forms a shallow shelf or ledge situated at the bottom of the receiving station and adapted at any given time to catch a limited number of certain types of mail from a mixed stream as it flows through the station. Additionally, the receiving station includes a vane-like member for selectively deflecting all of the mail from the transport. The operation of the member is under control of the delivery station and depends upon whether or not mail pieces awaiting further processing downstream are present in the station. The motion of the transport is controlled by both the delivery station and the processing equipment to insure that they will be kept continuously supplied with mail.

    Abstract: A method and apparatus for handling and transporting rod-like articles between production machines, for example articles such as cigarette filters between filter rod makers and cigarette filter tippers. Rods transported end to end along a longitudinal stream having the leading rods axially separated from the next adjacent rod by separator rollers which engage the rods of the stream, at least one of these rollers being a floating roller resiliently urged against the rod stream. The leading rods are successively deflected downwardly by engagement with and between the peripheries of a pair of rollers, the peripheral portions adjacent the stream of which rollers are inclined upwardly in the direction of travel and when the rollers rotate in the opposite direction such that both peripheries move downwardly adjacent the stream, they receive the leading separated rod, arrest its longitudinal movement and move it downwardly after which the rod is dropped onto a conveyor.

  • Patent number: 3978973
    Abstract: A machine that receives four rows of completely separated but closely spaced cartons from a customer printing and cutting press, and spaces each carton laterally and longitudinally from its neighbors for non-interference therewith. The machine aligns each independent stream of cartons with the longitudinal dimension of the overall machine and directs the streams of cartons to a switching device intended to control carton traffic to a primary automated stacking process or to an essentially secondary manual stacking process. The primary automated process passes the streams of cartons through an underlapping process, over an inspection table, through an inverting process, into a rate controlling hopper. From the rate controlling hopper, the cartons of each stream pass over a set of laterally disposed conveyors and into a discrete stack of cartons formed within a vertical hopper system that is the output receiver of this machine.
