This invention relates to cigarette delivery mechanism known as cigarette catchers by which the cigarettes delivered axially from a continuous cigarette-rod malnng mechanism are deflected transversely of the line of delivery on to'a collector band or bands upon which the cigarettes are adapted to lie in two parallel columns or rows.

It is known in cigarette catchers to provide a transversely movable deflector element comprising a bar mounted upon the crank pins of a pair of spaced crank discs so that the bar has an orbital movement and is maintained parallel to the line of delivery of the cigarettes.

With such an arrangement the cigarettes are deflected in pairs, the two leading cigarettes being transversely moved at each revolution of the crank discs. With-such an arrangementthe operative portion of the orbital revolution of the deflector bar occurs during acomparatively short angular displacement of the crank discs (inthe neighbourhood of about 40) so that it becomes essential to rotate the cranks at a comparatively high speed. This has the disadvantage that the deflector bar delivers a sharp blow to the cigarettes whereby damage is liable to be caused thereto.

It is an object of the present inventionto provide an improved form of deflector for a cigarette catcher in which the above disadvantages are eliminated. The object is attained by arranging that the operative period of the deflector during which the cigarettes are moved is of greater duration than hitherto, whereby a correspondingly'lower speed of the deflector is possible.

The invention consists in means for discharging cigarettes from a travelling conveyor on which the cigarettes lie parallel to the direction of travel,:wherein the cigarettes are deflected by a surface which moves progressively across the conveyor and has a movement in the direction of travel of said conveyor.

The invention also consists in means for discharging cigarettes from a travelling conveyor on which the cigarettes lie parallel to the direction of travel, comprising a cam element rotatable in a plane parallel to the conveying surface and having a cam surface adapted to move progressively across the. conveyor surface, the peripheral speed of the cam surface being approximately equal to the speed of the conveyor.

The invention further consists in means for discharging cigarettes from a travelling conveyor on which the cigarettes lie parallel to the dire'ction of travel comprising a pair of deflecting (Ci. 19s- -31)' delivered from the cut-off are received upon a travelling surface which moves at a somewhat higher speed than that of the cigarette rod whereby the cigarettesare spaced out. The travelling surface feeds the cigarettes to a pair of deflector elements comprising rotary cams which transfer the cigarettes from the travelling surface on to adjacent transversely disposed collector bands. Each cam element is adapted to deflect alternate cigarettes and they are mounted independently of one another, whereby they may be independently adjusted to bein correct. phase with the appropriate cigarette.

Each camfelement has a pair of oppositely disposed cam surfaces which extend for about 90 so that eachelement'deflects two cigarettes per revolution. I

Further featureslof the invention will be hereinafter described and defined in the claims.

- In the accompanying drawings:

Figure 1 is an elevation partly in section of a cigarette discharging apparatus according 'to the invention,

Figure 2 is a corresponding plan, Figure 3 isa sectional elevation taken on the line 3--3 of Figure 2, .Figure l is a sectional elevation taken on the line 4-4 of Figure 2.

In carrying the invention into effect according to one convenient mode byway of example an endless travelling band or spacer belt 5 is provided and is supported. upon guide wheels 6 and a driving pulley 1 so that an upper carrying lap 5c is arranged in alignment with the delivery of cigarettes from the cut-off; which is not illustrated, but may desirably be disposed to the right ofthe belt5, as seen in Fig. 1. This spacerbelt 5 is driven at a somewhat higher rate than the speed of delivery of the cigarettes and is adapted to receive the cigarettes and space them out. For this purposev means are provided for lightly gripping the cigarettes as they are delivered to the belt 5. This gripping. is effected by troughing the belt 5 at5b, providing a gravity plate 8 which is adapted to seat upon the cigarettes and lightly press them into the troughed part. I The troughing of the belt 5 is effected by supporting plates 9 and I0 which are shaped to provide a groove throughwhich the belt passes.

The plates 9 and ID are secured to blocks H and l 2 which are laterally adjustable by the adjusting screw l3 whereby the shape of the troughing may be varied to suit the cigarettes being dealt with. The adjusting screw I3 is carried by bearing plates l4 and secured to a mounting I6. The gravity plate 8 is provided with guide pins l1 freely passing through guides 18 conveniently carried by a shorts removing nozzle I9.

The upper conveying lap 50. of the band extends beyond the collector band 20 and lies slightly above the surface of such collector band, which is arranged in the usual manner transversely to the line of delivery of the cigarettes. The upper conveying lap 5a of the spacer belt may be supported by a platform or shelf element which is brought up as close as possible to the collector band and may be cut'away at one side according to the curvature of the band around its supporting roller.

Associated with the spacer band or web5 is a pair of cigarette deflecting devices, each of which comprises a rotary cam member 2! mounted to rotate upon a vertical axis. Each cam element is provided with two oppositelydisposed cam surfaces 2 la, 2 lb which extend for about 90, the rise of the cam being such as to extend across the spacer band a distance sufficient to ensure that the cigarette being engaged by the cam shall be pushed from the band. The intermediate parts 2 le of the cam members are concentric with the axis thereof.

The shape and disposition of the cam surfaces Zia, 2lb are such that when the cigarettes are fed by the spacer band into the deflecting zone, they are gradually pushed from the band by the cam surface.

The two cam deflecting elements]! are spaced apart a suitable distance to conform with the final spacing of the cigarettes on the catcher band and are driven in any suitable way, for example by spur gears 22, 23 meshing with an intermediate pinion 24. As the cigarettes are advanced by the travelling spacer belt 5 the first cigarette is engaged'by one of the cam surfaces of the first deflecting element at a point adjacent the commencement or low part of the cam surface and the cigarette is gradually pushed across the belt during its continual advance until the highest point of the cam finally moves it off the spacer belt on to the collector band. The following cigarette coincides with a part 2 lo of the first deflector cam element intermediate its two oppositely disposed cams 2la, 2lb and is thus not affected by such element and so passes on to be deflected by the second cam deflector. The cam deflector elements 2| are independently adjustable on their shafts so that they may be angularly adjusted to be in correct phase with the advancing cigarettes.

The peripheral speed of the cam deflectors is approximately equal to the speed of the spacer band so that the cigarettes and appropriate cam surface advance at approximately the same rate.

According to the preferred arrangement rotary brushes 25 are provided which in addition to preventing rolling of the cigarettes aid in maintaining the cigarettes parallel with the spacer band while under the influence of the cams.

The brushes 25 are mounted upon a spindle 26 carried in a pivotal mounting 21. The spindle 26 is driven by a belt 28 from a roller 29 in frictional contact with the collector band 20. The spacing of the brushes 25 from the collector band is adjustable by a screw stop 30 which engages a mounting 3| and is held down thereon by a spring 32. The brushes may be pivoted to an inoperative position in which they are retained by the spring 32. The mounting for the brushes is secured to the collector band support. The preference for such rotary brushes as a means for preventing rolling of the cigarettes and for maintaining the cigarettes parallel with the spacer band while under the influence of the cams is not intended to exclude the use of other forms of devices of ancillary character, such as a resilient roller of known or otherwise suitable type of that purpose, and hanging retarding curtains or the like.

The drive for the spacer belt 5 and the cam deflectors 2| is taken from a shaft 33 driven from any suitablepart. This shaft carries a gear 34 which drives a gear 35 on the spindle 36 of. the belt drum 1. A second gear 31 on the shaft 33 drives a gear 38 which is secured to a vertical spindle which drives the intermediate pinion 24 by which the cam gears 22, 23 are driven.

A nozzle 39 is provided for removing shorts from the spacer belt 5 at its forward end. This nozzle 39 and the nozzle l9 are connected to a suitable source of suction.

It will be appreciated that as the cam portions of each cam deflector each occupies an arc substantially the speed of the elements will be considerably lower than in the known apparatus whilst the objectionable feature of impacting on the cigarette is avoided.

Moreover by the arrangement of the spacer band over the collector band as described above there will be practically no drop of the cigarettes as they are deflected on to the collector bands.
