INVENTOR: GEORGE DEARSLEY BY am ATTORNEY United States 2,953,235 CIGARETTE TURNING DEVICE George Dearsley, London, England, assignor to American Machine & Foundry Company, a corporation of New Jersey Filed Feb. 27, 1957, ser. No. 642,856

12 claims. (c1. 19a-3s) This invention relates to the manufacture of cigarettes, and more particularly to la `device and method for turning end-for-end tipped cigarettes received by a collector in 'a cigarette making machine so a's to cause the tipped ends of lall the cigarettes to face in the same direction.

In the cigarette manufacturing process, cigarettes having iilters, cork tips, lor hollow mouthpieces formed on one end are discharged and collected transversely in two rows onto a collector belt. vDue to the method of manufacturing and cutting that is employed in rnaking such; tipped cigarettes, the tip ends of the cigarettes in each row face in opposite directions. The cigarettes in one row then have to be turned so that the tip ends of this row of cigarettes will face in the same direction as the tipped ends of the cigarettes in the other row before the tipped cigarettes having their tipped ends all facing the rsame direction are transferred in suitable containers toV a, cigarette packaging machine.

Various devices have been devised heretofore for turning cigarettes end-for-end. Some of these devices have been expensive to construct, others have been unreliable in handling cigarettes in excess of 1,000 per minute, and

others have damaged the cigarettes in turning themv endfor-end.

I t is an object of this Ainvention to provide a cigarettev turning kdevice which will be capable of turning cigarettes end-for-end at the same rate that they Iare manufactured by high speed'cigarette making machines.

Another object is to provide a turn-:around device which will operate at a very slow rate of speed in turning cigarettes but which will have 'a large capacity so that if any diliiculties should be encountered in the opera-A tion of the turn around device such as a jam it would not interfere with the continued operation of the cigarette making machine, and there would be sufficient time Vfor the diiiiculty to be rectified. h i Y Y"A further object of this invention is to provide a cigarette collecting and turn laround device which will allwfor normal cigarette inspection at the collecting:

table before the tipped cigarettes reach theturn around deyice.

.. Another'objectis to provide a collector `with a turn around device whichpcombines tworrows of tipped cig arettesrfacingflin opposite directions into a singleV rowA with-.allofthe tipped ends of the cigarettes in thev single row-.facing in the same directionj further object is'to provide a cigarette turnaround apparatus which travels at: a' slow rate of speed but A further object is to' provide a conveying device for turning batches of cigarettes end-'for-end.

Other objects and features of the invention will'ap`l pearas the description of the particular physical ernturns a 'large number of cigarettes're'ndice 2 plied to corresponding parts throughout the several views which make up the drawings.

My invention comprises delivery and receiving conveyor belts traveling in a horizontal plane and a turn around yconveyor traveling in `a vertical plane.k While` various suitable apparatus could be employed to carry my invention into elect, I have shown how this may be accomplished by means `of a water wheel type ofcouveyor coacting with a pair of horizontal receiving and; delivery belts. l

In the embodiment used to illustrate the invention, twov rows of tipped cigarettes Cand C1 aredeliveredfrom-,a

cigarette `making machine producing tipped cigarettesl such as, for example, that shown in my co-pendingappli-l cation Serial No. 509,293, iiled on May` 18, 1955,'or

from a machine such as shown in U.S. Patent `No.1-Re-.Y

issue 19,375, granted November 20, 1934, to W, .BfA Bronander. The tipped cigarettes in each row ofcig- -arettes so ydischarged on the collecting belt 14 havethe tipped ends in each row facing in opposite directions: The collecting belt 1.4 travels over a suitable pulley 15 in the direction indicated by the arrow.

These two rows of cigarettes C and C1 are delivered from the collecting belt 14 over a bridge 16 onto alpair of collecting

belts

18 and 20 traveling in the direction indicated by lthe arrows; The cigarettes C on collecting belt 20 .are discharged onto 4a suitable collectingptable 2.2 shown in Figs. 1 `and 2. 'Y f Belt 18 travels over

suitable pulleys

17 and 19 while belt 20 travels over suitable pulleys Z1 and 23. Pulleys 19* and 23 are mounted on a common shaft 56 which4 v is driven by a suitable pulley v25 through'a-belt 27 Lfrom water whee typ'e of: e

a suitable source of power such as the main drive of a; cigarette making machine. 1 1, The cigarettes Clon belt -18 are advanced to the slide 24 which they roll over into the receiving pockets or buckets 26. The floor 78 of the receiving buckets-26 have declining surfaces so that the cigarettes C1 roll tothe bottom and rear of the bucket. The ceilingfsurfaces 80 of buckets 26 have similar declining ejector surfaces. Each bucket is preferably of such size that, it can holdv at least ten cigarettes, thereby permitting the conveyor 30 totravel at a relatively slow speed. As the buckets or pockets 26 are elevated in the direction indicated by the arrow in Figs. 3 and 4, the cigarettes C1 areconined in the` buckets 26 by the retainer plate 28.

In the embodiment of the turn around conveyor, the; individual buckets 26 are connected to an endlessl conveyor such vas sprocket chain 30 traveling inthe direc'- tion of the arrows (Figs. 2 5), over pulleys orsprockets 32 -and 34. Sprocket 32 is ixedlyprnounted on'` Q 82. whichin turn is rotatably supported in 'bracketfSS Patented Sept. 20,

The sprocket 34 is xedly mounted on a shaft 36 to which is also iiXedly secured a second sprocket 38 which is driven by the belt or sprocket chain 40 in the direction indicated by the arrow. As the cigarettes slide down theslide 24 yand come to rest in the bottom of pocket 26, they are moved upwardly in the direction indicated by the arrow in Fig. 4.

After the buckets 26 travel upwardly around an arc as shown in Fig. 3, land commence descending, the cigarettes C1 roll down the declining surface 80, formerly the ceiling 80 on the upward travel, of the individual buckets 26 in the manner shown in Fig. 5. The cigarettes C1 are prevented from falling out of the pockets 26 by means of the retainer plate 28 as they are turned around by sprocket 32 and commence their descent as shown in Fig. 5.

When the descending cigarettes C1 which are held in their respective pockets by the retainer plate 28, as shown in Fig. 5, pass beyond the lower tip end 29 of the retainer plate 28, they roll down the declining discharge guide 42 onto the collecting belt 44 which delivers discharged cigarettes to the collecting table 22.

The cigarettes delivered to the collecting table 22 all have their tip ends facing in the same direction as the tipped cigarettes C1 received from belt 20.

The belt 44 travels over

pulleys

46 and 48. Pulley 48 is mounted on a shaft 50 which also has mounted thereon a pulley or sprocket 52 which is driven by a belt or sprocket chain 54, causing the belt 44 to travel in the direction indicated by the arrow.

The

collecting belts

14, 18, 20, and 44 may be driven Iat the rate at which collecting belts are normally driven in a cigarette machine to allow an operator sufficient time to remove any defective cigarettes that are noted. Due to the large number of cigarettes C1 that can be picked up in the collecting buckets or pockets 26, the turn around elevator, which resembles in effect a water Wheel, receives a large number of tipped cigarettes C1 facing in one direction and conveys them around with the Wheel at a relatively slow rate of speed whereby they are discharged facing in lan opposite direction upon the collecting belt 44. Due to the large capacity of the vertical conveyor, Fig. 3, it is possible to avoid shutting down Ithe operation of the cigarette making machine should the turn around apparatus, for one reason or another, temporarily become jammed, thereby giving the operator an opportunity to remove the jam without interfering with the continued operation of the cigarette making machine, and hence does not stop production.

In the modified form of my invention, shown in Figs. 7 and 8, the carrying buckets 76 have

slots

78 and 80 formed therein. Forked arms or fingers S2 and 84 extend into these slots from the discharge slide 86. As the buckets 76 descend past the retainer plate 88, cigarettes carried thereby roll down the

fingers

82 and 84 over the shield 86, onto the belt 90 which delivers them to the collecting table. This construction has the Vadvantage that if any of the cigarettes hesitated in the pockets 76, they would be positively stripped therefrom by the

fingers

82 and 84.

Due to the arrangement and capacity of the turn around device disclosed, it is capable of turning cigarettes C1 end-for-end at a slow rate of speed, while still keeping up with the speed at which they are manufactured in a cigarette making machine, avoiding the formation of co11ars, indentations, or wrinkles in the finished cigarettes due to sudden acceleration and deceleration of the tipped cigarettes.

' It will also be noted that all of the cigarettes C and C1 issuing both from the cigarette making machine and the cigarette turning apparatus :are collected in a single row` facing in one direction so that there is no need for an operator to remove cigarettes from a plurality of rows. Also in the arrangement disclosed, it is possible for an operator to immediately inspect the cigarettesras they are discharged from the maker in the same way she now does, thereby enabling adjustments in the maker to be immediately made without having to wait for the cigarettes to pass through the lturn around device first.

From the foregoing description, it will be seen that I have provided a collecting conveyor traveling in a horizontal plane and an endless turn around apparatus operating in a vertical plane whereby cigarettes are delivered to one side of the vertical conveyor and carried upwardly The invention, therefore, is not to be restricted to the `precise details of the structure shown and described.
