Definitions

  • FIG 2 TORNEY Nov. 19, 1935.
  • the improved machine consists of a stationary tobacco maganine orhopper provided with intermittently oscillating agitators adapted to rake the tobacco towards the outlet of the hopper, an oscillating transfer pocket beneath the hopper outlet, an automatically operated spill catcher beneath the transfer pocket, a measuring chamber provided with an automatic gate adapted to be opened to admit tobacco discharged from the transfer pool-set and the spill catcher, charge-compresslng mechanism controlling the operation of the transfer pocket, a charge-cutting and transfer unit including a swinging charge-measuring pocket, and a bunch rolling mechanism.
  • the scrap tobacco is placed in the hopper in which it is agitated and carried irom both sides thereof towards a centrally located outlet by two sets of agitators which are so actuated as to move a the tobacco mass on their forward swing but to leave it practically undisturbed on their return swing.
  • Below the outlet of the hopper is an oscillating horizontal drum-shaped structure con-e ing position, the pocket-closing knives are open so that tobacco raised by the agitators can fill the p pocket.
  • the drum makes its forward half-turn, at the start of which the knives-fare" closed and at the end of which they are reopened, permitting the charge to drop into a measuring chamber therebelow, the cam-operated gate of the latter having opened before the forward turn of the transfer pocket.
  • the knives which were closed upon movement of the pocket from the delivery position, are again opened to receive a new charge, and the gate of the measuring chamber is closed and the column of loose tobacco therein'isrpushed by a horizontally slidable .spring-tensioned plunger into a, charge-measuring pocket into which it is thereby compressed to the proper density determined by the adjust ment of the plunger spring.
  • the transfer pocket as in the machine of the patent referred to above, is designed.v to hold an excessive quantity of tobacco, and the compressing plunger is provided with the ratchet drive de m scribed in the patent cited above to stop the oscillation of the pocket for one cycle whenever surplus tobacco sufficient at least fora full charge has accumulated in the measuring chamber.
  • the main object of the invention is the production of an improved machine having a novel combination of elements and a novel mode of operation.

  • a hopper for holding asupply of scrap tobacco, the hopper being provided with an outlet, a transfer pocket underlying said outlet, a measuring chamber underlying the pocket and provided with a hinged gate adapted to be swung open to admit tobacco to the measuring chamber, mechanism for intermittently oscillating the pocket to move it into registry with the outlet of the hopper to receive a quantity of tobacco there'- from and then carry said quantity into position above the measuring chamber for delivery thereto, means independent of said mechanism for swinging open the gate while the pocket is in filling position and keeping the gate open while the pocket oscillates, knives coasting to separate the quantity of tobacco in the pocket from the mass of tobacco in the hopper and then confine it in the pocket while it is being carried into position above the measuring chamber, meansfor closing and separating the knives, means for compressing the tobacco deposited in the chamber, and means for severing a bunch charge from the compressed column of tobacco in the chamber and transferring the severed charge to bunch rolling position.
  • opposed sets of oscillatory agitators in the hopper for raking the mass of tobacco from the sides of the hopper toward the outlet
  • the charge-severing and transferring means includes a vertically reciprocable slide-rod, achargecutting knife supported from said rod, a chargemeasuring pocket normally supported from said rod in a horizontal position aligned with the measuring chamber to form a continuation thereof, a device for turning the pocket into vertical position after the charge therein has been severed by the knife, and mechanism for ejecting the charge from the pocket when the latter is in a. vertical position.
  • side frames l5, l5 support a table l6 upon which are mounted pedestals l1, IT, a support block l8, and a pedestal frame I 9.
  • 5 also support the main shaft 20 of the machine which is driven in the manner shown in the above mentioned patent.
  • the shaft 20 carries cams 25, 26 and 21 which actuate cam levers fulcrumed on a shaft 29 journaled in frame I 5 and a bearing 28.
  • the pedestals H, H support the hopper 30 and carry a shaft 3
  • the support block l8 carries the measuring chamber 33 and the bar 34 on whichthe charge-compressing plunger 35 is slidably mounted as hereinafter described.
  • On the pedestal frame I9 is mounted. the charge-measuring pocket 36, normally forming a continuation of the measuring chamber 33, and constituting a part of the charge-cutting and transfer unit 31.
  • is oscillated by means of the arm 22 fixed thereon and connected by a rod 83 to a cam lever 84 having a roller in engagement with the track of the face of cam 25.
  • engages with a ratchet 45 attached to sprocket 50 which is loose on shaft 2
  • a retaining pawl 23' pivoted on pedestal prevents the ratchet from turning backward on the return of the driving pawl 23.
  • On shaft 49 is 10 mounted a crank 46 connected by a bar 48 to shaft 42. The bar 48 is in turn connected by a.
  • has attached to it a concentric ring 6
  • One of the inturned ends of this spring namely the 30 trailing end with respect to the direction of rotation of the ring 6
  • is journaled in the pedestals H, 50 I1 and alternately turned forward and back by means of a gear 53 thereon meshing with a reciprocating rack 54 connected by a rod III to a cam lever 55 carrying a roller 56 engaging in the track of face cam 25.
  • the rack 54 is guided by 55 a flanged roller 1
  • the hub of pocket 53 carries radial spokes I6, and the guide ring 32 at one end of the pocket 63 is secured thereto and to the spokes 16 by screws passing through countersunk holes 7 in;the ring, the guide ring 32 at the other end of the pocket 53 being secured to that end of the pocket 53.
  • the pocket 63 is provided with removable inserts 64 which may be replaced by inserts of different thickness to adapt the maa dress chine to bunches of widely difiering sizes, and the outer side faces of the pocket 63 are fitted withresilient pads 65 which act as bufiers for the lever it and the spider l5 in their closed position.
  • One arm of the spider it carries a horizontal shaft ll.
  • On the inner end of the shaft ii are keyed two epicyclic gears it and it meshing with the gear segments l2 and it, respectively, to oscillate the pocket t3 and lever it, as will be presently described.
  • the lug illl rests against a stop screw its, Fig. 2, carried by a block lid attached to pedestal i'l, thereby holding the knife 66 open, the knife 6? having been relatively moved into open position with respect to pocket 63 by means which will now be described.
  • the epicyclic gears iii and it! Upon engagement of spider l5 with the pocket 63, the epicyclic gears iii and it! remain idle on the shaft ll until the arm dd on the latter meets the stationary roller til supported by a bracket 88 attached to pedestal ii, at which time the pocket 63 is moving into discharging position.
  • the shaft if is turned back with the epicyclic gears it and Y9, whereby the gear 18 drives the gear segment l2 and moves the pocket 63 relative to the knife 6'1! into discharging position and the gear 19 drives the gear segment 13 to swing the arm it with the knife 66 out from the closed position of the latter and into open position with respect to the discharging position of pocket 53.
  • the hopper outlet is closed by the knife 6? while the pocket 53 is in i5 transit to and from discharging position.
  • the length of the knife G'l must be sufficient to close the hopper outlet when the knife is at the limit of its forward swing.
  • the knife til, Fig. 3 is positively actuated since it is rigidly connected to the shaft Si, by the spider H5. 'The reason for positively operating the knife or jaw 61 is 30 that this is the knife which cuts off any straggling scraps, by carrying these scraps past a stationary shear blade 66:: arranged beside the path of movement of the jaws as shown in Fig. 2B, and when this knife was spring closed, as so in prior constructions, these scraps would hold the Jaw open against the tension of the spring.
  • a scraper d'ia prevents scrap from being caught between the wrapper and transfer on its return.
  • the bottom of pocket 63 is provided with a perforated false bottom ii i and has a. duct i i2 communicating with a pipe H3 fitting into a bore of a disk lid turning on the hub of arm M.
  • the to bore in the disk lid registers with a duct in pedestal if when the pocket 63 is in filling position, so that in this position the contents of the pocket are subjected to the action of suction by means of a pipe H5 communicating through the duct 65 in the pedestal I! with the pipe H3 and connected to a suction chamber H6 attached to base it, the suction chamber being provided with a. pipe i I! leading to a suitable suction unit (not shown).
  • Each quantity of tobacco in the pocket 63 is thus '10 freed of dust as it enters the same.
  • the rings 32 are guided by plates i I8 a'tached to lugs H9 of the hopper 39, the lugs H9 also carrying housings BI and M.
  • a chute I2I which directs the quantity of tobacco T discharged from pocket 63 into a conduit leading to the measuring chamber 33.
  • the tobacco is thrown at an angle to the surface of the chute so that the chute has a placing effect (for instance by tilting the chute, the proper amount of tobacco for tapered bunches can be placed toward one end of the bunch), and also the impact of the tobacco on the chute tends to break up wads of tobacco.
  • the tobacco was thrown in the direction of the length of the chute so that some tobacco did not even touch-the walls of the chute and therefore the chute had very little placing effect.
  • in lugs provided for this purpose, carries a transverse shaft I22 which is tensioned by a spring I3I and to which a curved tray I32 is affixed, in position to receive any tobacco spillage from the pocket 63, Figs. 1 and 2.
  • the tray I32 is connected by a link I36 to a lever I31 loose on shaft 2I.
  • Link I36 is slotted at its joint with tray I32 to allow lever I31 sufficient movement for opening the gate 82 of (he measuring chamber 33 before swinging out the tray I32 to discharge the accumulated tobacco spillage into the measuring chamber 33.
  • the gate 82 When the gate 82 is 13811, as shown in dotted lines in Fig. 1, it forms the rear wall of the conduit referred to above, the same having a front wall I52 and side walls I53.
  • the cam 25 is so timed that the gate 82 is opened while pocket 63 is in filling position and remains open at all times whenever there is any movement of the transfer pocket 63, thus allowing all tobacco dribbling from the pocket during such motion to drop into the measuring chamber 33.
  • Only one gate 82 is used instead of two gates as formerly because the edges of the gates came together where the pile of tobacco delivered was highest and pinched tobacco. With one gate as here, the tobacco is directed somewhat away from closing edge of the gate and the gate closes at the point where pile is low.
  • the cam track of cam 21 is so shaped '(Fig. 1) that the plunger 35 during its forward movement has a hammering motion, going forward and back a number of times before its final forward stroke, thus obtaining a uniform density in the column of tobacco and eliminating voids.
  • the rod 93 carries a finger I02 which normally engages a trip lever I03 pivoted on support block I8 and connected through a rod I08 to the ratchet drive of 29 the rack 54 to control the same in the manner described in the patent referred to above.
  • a certain limit which may correspond to an excess sufficient for one or more additional bunch charges
  • the plunger 35 does not travel far enough to permit the finger I02 to engage lever I03, whereby the ratchet drive of rack 54 is incapacitated, thus preventing the oscillation of the feed pocket 63 during the next cycle of the machine.
  • a bracket I21 projecting into an opening of a block I28 carried by vertical slides I29 in frame I9 and affixed to said block by a pin I30.
  • the slides I29 which are held in their ways in frame I9 by retaining strips I33, carry the knife I24 and in turn form the slideways for rails I34 Joined by a. tie plate I35.
  • the springs I40 hold the plates I39 against horizontal studs I42 in frame I9.
  • the stop screws I44 in plates I43 on the upper ends of the slides I 29 engage plates I39 and depress the slide rails I34.
  • the ejecting rod its is held in an arm i'ib iulcrumed on a lever iii pivoted in a lug. iii attached to block lZd, and the lever iii is tensioned by a spring lid anchored to a bar li t on block 028.
  • the arm l'it is guided by a bell crank-lever lib pivoted in bracket it? and carry ing a roller Mid adapted to enter the recess of a cam piece Mid supported by frame it.
  • the roller t lt snaps into the recess of cam piece ltd, thereby turning the levers iii and lit into the dotted positions shown in Fig.
  • the plunger 6% compresses the rectangular charge T" in pocket 36 into a substantially square charge 38 on the bunch rolling table before dis charging it, thereby putting it into shape necessary for the formation of a perfectly round bunch E.
  • the spring iiti which controls the' ejecting pressure on the charge T" in the cutting chamhers is adjustable by raising or lowering the bar i'lil which for this purpose is provided with elongated slots for its fastening screws.
  • the charge-measuring pocket which serves to transfer the bunch charge to the Chianti belt has no gate to close its open end. There is little tendency for the tobacco to fall out of this chamber ead of time during transfer because the chamber is lowered while in horizontal position to a point where its open end practically touches the Chianti belt which from then on closes its open end.
  • the relatively narrow charge is delivered at right angles to the Chianti belt and tends to spread out and be broken up to form a bunch without fiat sides and the relatively narrow cut surface also minimizes flats on bunches.
  • the same arrangement makesit possible to secure, a convenient variation in bunch thickness by adjusting the screws it? which limit the inword movement of the plunger use, an important feature of the present device.
  • knife as applied to the arcuate members db and ti should be understood as being employed in a generic sense to refer to a blade (which may be blunt) or to parting or separating devices to part one portion of a mass of loose material from another. Therefore unspeciflcation and claims is not to be construed as limited to a device havingan edged,cutting or shearing action.
