This invention relates to cigarette collectors for continuous rod cigarette machines and is intended to receive the cigarettes as they issue in a single line from the cutoff and deliver them in side by side row formation.

There are many devices for this purpose but, when used at high speed, most of them are either too severe in their treatment of the cigarettes and especially the ends of the cigarettes, or they fail to lay the cigarettes down in reasonably exact alignment and parallelism. The principal object of the invention is to provide a collector which will overcome these diiliculties and which will becapable of use at the highest speeds of which cigarette machines are capable. To this end it is an object of the invention to provide a collector in which the endwise travel of the cigarettes 'is retarded by the gentle action of suction, instead of by the mechanical resistance of a stop, with necessarily harsh action on the ends of cigarettes traveling at high speed. Y

Still another important object is to provide for accurate placing and aligning of the cigarettes without however the use of pocket walls to segregate and position cigarettes. In the latter type of machine, While alignment is commonly` good, the pocket walls are a source of considerable trouble when the cigarettes for any reason open up or the cutoff is out of time with the collector because at the point where the ends of the walls pass the line of cigarettes, under such circum- 4 stances, a windmill action takes place which tangles up and scatters cigarettes andV tobacco. 'I'he present device makes it possible to eliminate such pocket walls or partitions and at the'same time holds the cigarettes in exactly separated spaced positions for accurate spacing and alignment on the delivery belt.

Another object of the invention is to insure a clear cut separation of cigarettes and a firm grip on the cigarettes by the suction means through the shaping of the cigarette engaging portion of the suction means and through the positive engaging of the cigarettes with the suction means. Another object of the invention is to provide a collector which will deliver cigarettes with the seam side or the printed side of successive cigarettes facing in the same direction thus eliminating elaborate devices often hitherto used to obtain this uniformity ordinarily lost in the collector. In this connection itis an object to maintain the uniform rotational arrangement of round as well as oval cigarettes. With these and other objects not specifically mentioned in view, the

invention consists in certain constructions and combinations which will be hereinafter fully described'and then particularly pointed out in the claims hereunto-appended. In the accompanying drawings in whichlike characters of reference indicate the same or like parts, Fig. l is a plan view of the improved collector; Fig. 2 is a sectional side elevation of the cigarette collector, omitting the suction. drum to show the parts behind;

Fig. 3 is a detail view in sectional elevation of the suction drum on the line 3-3 of Fig. l;

Fig. 4 is a section in elevation on the line 4-4 of Fig. 1;

Fig. 5 illustrates a modied form of the invention for delivering aligned cigarettes in two rows. In carrying the invention into eect, there is provided in a cigarette collector, a combination of devices for delivering a line of endwise moving cigarettes, with suction means which are relatively stationary with respect to the endwise movement of the cigarettes and which. act as a brake on said cigarettes to retard or stop their endwise Y movement. In the best constructions said suction means comprises a rotating suction drum and preferably the rotating suction Vdrum has suction ports arranged to extend alongside the line of cigarettes. In the best forms, means are provided for positively pushing the cigarettes from the endwise moving line into contact with said suction ports.` A Referring now to Figs. 1 to 4 of the drawings, the cigarettes C as they are delivered in an endwise moving line from the cutoff, (not shown) of a continuous rod cigarette machine, are forwarded between upper and lowerv belts II and I2. 'I'hese belts travel at a speed greater than that of the cigarette rod in order to space the suc.- cessive cigarettes. Cigarettes are forwarded by these belts alongside the collector drum I3 which has a series of grooves I3a parallel to its axis on its periphery, which grooves .through suction ports I5 with a suction chamber S within the drum which is o f hollow cylindrical construction. 'I'he drum while rotatable transversely of the line of cigarettes, is immovable communicate lengthwise of the line so that the suction through While the cigarettes may be forwarded in close contact with the drum for removal by suction alone, in a preferred form a pusher is provided for positively seating the cigarettes in the grooves I3a and against the suction ports. The advantage of employing grooves with suction ports in their bottoms is that the cigarettes'are engaged for a considerable portion of their circumference instead of along a single line of contact.

As the drum i3 rotates, the pusher I4 forces the cigarettes against the suction ports and the drum carries the cigarettes a quarter turn to a position where said cigarettes are picked oi by delivery belts I6 and transported to a stationary table, where the cigarettes are arranged in side by side accurately aligned formation which facilitates inspection and packaging and enables the operator to handle more cigarettes per minute than otherwise possible. The suction drum I3 is secured to one end of a shaft I1. On the other end of this shaft is a gear I8 adjustably attached to a hub I9 which is secured to the shaft I1. The shaft I1 is driven through gears I8, 29, and'2I from gear 22 on the shaft 23 which gears establish a ratio of l to 24 between the shafts I1 and 2'3 for a drum having 24 cigarette receiving grooves, so that a groove comes opposite the cigarette line for each cigarette forwarded.

The pusher I4 is given an orbital movement toward and across the'cigarette line while moving along said line, then away from the line and so on, and for this purpose is secured on cranks I4a on the

shafts

28 and 29 which are driven through spiral gears 24 and 25 on shaft 23 engaging with

spiral gears

26 and 21 on the

shafts

28 and 29,

shafts

23 and 28 and 29 being driven at a 1 to l ratio such that there is one cigarette pushed for every cycle of operation of the cigarette machine. This shaft 23 through a spiral gear 30 drives the spiral gear 3| on shaft 32 which in turn drives the guide belt II as already described. A gear 33 on the shaft 32 through gear 34 on the shaft 35 and pulley 36 drives the lower guide belt I2 at the same speed as the guide belt II. A suction conduit and chamber S connects with the hollow interior of the collector drum I3 as shown in Fig. 3, through a manifold sleeve 31 which is held by the pressure of a spring 38 in substantially air tight relation to a iiange 39 on the drum I3. A valve 48 on the valve stern 4I is adjustably secured by arm 42 to a bracket 43 which serves to hold the valve stationary against movement with the drum. As shown in Fig. 4, the suction chambar S formed by the valve and conduit is so ar-V ranged that the limits of the suction chamber act to turn on suction to the ports I at a point just preceding the receiving of a cigarette from the delivery belts II and I2 and cuts off the suction at the point where the cigarettes are delivered from the drum about ninety degrees from the first mentioned point'onto the delivery belt I6. It is noted that the delivery belt I6 runs in grooves I6a in the suction drum so that the belts do not interfere with the action of the grooves I5 and yet underlie the cigarettes so as to produce a gradual but positive separation thereof at the delivery position. These belts being spaced, permit shorts and cigarette pieces to drop out between the cigarettes and thus act as an automatic inspection device for such defective cigarettes.

Referring now to Fig. 5, a modified form of the invention is shown for the purpose of delivering aligned cigarettes in two rows with the cigarettes arranged side by side. The construction of this form is substantially the same as that shown in Figs. l to 4 except that -the drum 53 is made somewhat more than twice as long and is provided with two circumferential sets of grooves- I3a and ports I5. The pusher 54 extendsv alongside both sets of grooves and is timed to operate vonce every second cycle of the cigarette machine to push two cigarettes at a time into contact with the two sets of suction grooves which are delivered by two sets of side delivery belts 56 in rows. The drum 53 is carried by the shaft 51, which also carries the valve stem 55. In this form, the drum 53 is rotated at a speed such that aligned grooves -I3a arrive in cigarette receiving position once Afor thev delivery of cork tipped cigarettes and for use with very high speed cigarettes machines where one girl cannot take care of the delivery int one row.

It is noted that by reason of the suction principle employed in the present device, a machine has been provided which is gentle in its action on the cigarettes by reason of the fact that any sudden halting of the cigarettes against a stop engaging the ends is eliminated. It is noted that the present collector has no deep pockets or partitions extending between successive cigarettes and so that there is no likelihood of cigarettes when fed opened up or out of time with the cigarette machine becoming caught or mangled between partition walls or scattered windmill fashion by said walls and that the structure is substantially self-clearing since it has no parts on which cigarettes or shorts may be caught. Another advantage over the present construction asV compared with one with partition walls is Ythat it may be of relatively small diameter as compared with the pocket wall construction in which the walls must be made far enough apart to secure complete entry of the cigarette between said walls. While the present invention has been described in connection with a drum type collector, it should be understood that the invention is applicable to other types of collectors. 'I'he parts above described may be widely varied in construction, within the scope of the claims, for the particular device selected to illustrate the invention is but one of many possible concrete embodiments of the same. 'I'he invention therefore is not to be restricted to the precise details of the structure shown and described.
