England Application June. e, 1931, serial No. 542,617, and 7 in Great Britain June 7, 1930 f This invention relates to cigarette packing inachines, and has for its object to` provide vmeans whereby cigarettes may be located with their printed matter all facing in one direction and jface upwards so that they may bepacked in this manner, and thereby enhance the appearance of the finished package.

It should be explained that cigarettes always have the printed matter located in a denite po- ;sition with respect to the seain and generally the printing is on the opposite side to the searng 1 The invention comprises a cigarette turning device for use on packing machines comprising means for rotating the cigarettes about their axes',

, and means for arresting the rotation of the cigarettes when the saine are disposed in a predetermined position. l

The invention will be more particularly described with reference to the accompanying drawings, in which:-' Y

Fig. 11 isan elevation in diagrammatic form of a further modification, and i 12 is a plan of Fig. l1. Referring to Figs/1 to r7, the cigarettes are placed in a hopper (not shown), and fall down v the slots between a number of vanos 1 on to a plate 2. This plate is furnished with a number of curved grooves which locate the cigarettes in po siticn. The cigarettes are fedout in rows from beneath the vanes by pusher pieces 3 carried on a chain conveyor 7 and the cigarettes pass beneath a brush 22l and a plate 2b` having grooves corresponding to those in the plate 2 (see Fig. 5). The cigarettes are delivered on to a series of rollers 8 which are preferably knurled. The rollers are mounted in bearings formed in a horizontal frame 9 parallel to one another and separated ving ends of the cigarettes so that they `are Afree to rotate in the same direction When driven in the manner hereinafter described. y y s The cigarettes 10 are delivered on to the rollers 8 as shown inFig. 2 so that the longer axis of each cigarette lies centrally disposed between an ad'-` jacent pair of rollers.

The rollers are then rotated for about two revo-` lutions by means ofintermittent gearing. small blade 1l which is preferably a piece of' spring steel provided with a sharp end is ari ranged so'that itV lies approximately tangent/ital with respect to the periphery of each cigarette (see Fig. 6),`and as the cigarettes rotate,- the seams, whichV are formed as shown in Fig. 7, eventually come into Contact with the extreme'v points of the blades and each cigarette is instantly arrested although the rollerskmay continue to rotate. U A Y f In order to prevent the cigarettes from comingY into contact with the pointed blades l1 before they Vare in the required position on the rollers, Y

a movable guide 12,`suitably grooved to correspond with the groove in plates 2 and 2b, over Which the cigarettes are fedc'is arranged in" front of the entry to the rollers,` and the guide 'is raised sufficiently to enable the cigarettes to clear the InFig. 1 theV guide 12` is carried on an arm pivoted at 13 and operatedby a cam 14. A mov-V blades as they'passon to the roller.'

able stop 15 is also arranged to receive the lead and'locate them in position, and in the present case the stop 15 is carried on an extension of the arm carrying the* I y guide 112.` `As soon as the lcigarettes are in thev required position, the guide 12 drops, and thev cigarettes fall into contact Vwith the rollers v8,` as previously mentioned; the Weight .of vthe cigarettes depressing 'thespring blades,` 1l to ajvery sligi t extent. The rollers have Worm" wheels 16v formed on the Vends thereofwhich engagewith a worinV 17. The Worm 17 vhas ajsmall gear 18. on the end thereof which' is rotated by a large gear 19. The gear 19 is integral with a ratchet wheelQO (see Fig. 3), the latter being intermittently rotated by a pawl 2l 'driven by aV link 22 connected to the cam disc 14 which is continuously rotated. The disc 14 is fixed to a spindle carried'in a bearing 23 and driven'by a sprocketv Wheel (not shown). yAfter the rollers have rotated twice, all the cigarettes will be found to lie in the required position, and they are then transferred by the pusher piece 24 of a conveyor 25V i The pusher piece 24 is controlled by a fixed trip 24e, Fig. 1, to cause it to rotate clockwise about its pivot and avoid the cigarettes deposited on the plate l26. The cigarettes are removed for insertion into the packets by a conveyor (not shown) During this movement the cigarettes pass beneath the plate 27 having guides 28 which prevent the cigarettes from being displaced.

In the case of non-circular cigarettes, for

example, oval cigarettes, the devices shown in

Figs.V

8 and 9`1nay be used in orderY that the periphery of the cigarette shall move into contact with the point of the blade throughout the revolution of thecigarette, and in order tol effect this, a plate 29 may be Vprovided as shown in Fig. 8 which forms a at suriace over which the cigarette can ride, thus ensuring that the periphery is always definitely in contact with the blade point in spite of the shape of the cigarette.

In Fig. 9 the rollers are separated somewhat Widely so that they will just support an oval cigarette when itis lying at and a third roller 30 is interposed as shown which supports the oval. cigarette when it is standing on the 1longer axis of the oval. y l

As an alternative, the blade may be given any required movement in order to enable it to conform withr therperiphery of a non-'circular cigarette when thesame is being caused to rotate by the rollers, but generally speaking, the apparatus shown in Figs. 1 and 2will handle all lcommon shapes of. oval cigarettes, and the modifications mentioned above would only be required for abnormal shapes.

kReferring to Fig.` l0, this shows diagrammatically a further method of carrying out the invention.

band 31 which, at the moment of delivery, is

stationary. The band is kthen moved a short distancein theV direction of the arrowand the friction of the band is suihcient to cause the oig- L arettes to rotate until they are arrested by the blades`32. Guides 33 prevent the cigarettes from moving bodily along the band. After the ciga- 1 rettes have been rotated to the required position,

the band comes to rest again and the cigarettes are removed to the packing machine.

Referring` to Figs. 11 and 12 which show diagrammatically a further way of carrying the inv vention into eiifect, the' cigarettes are delivered fromthe vanes 34 byA a plunger 35 on to a flat bristle brush 36. The'brush is one of a series carried on a chain conveyor 37 intermittently moved in the directionof the arrow. The brush is at` rest 'at the moment the cigarettes are delivered on to it and is temporarily inclined so that the cigarettes .tend to roll towards the needle means of a rotary striker 41, the plates being of spring steel to permit the brush to vibrate Without disturbance oi the chain conveyor which y moves in guides 42.` The bristles of the brush are all inclined at the same angle to thehorizontal Y' and the result or the vibration is to cause the cigarettes to rotate by the frictional ratchetaction The cigarettes are delivered by any.

suitable mechanism to an intermittentlymovedV Lof the inclined bristles upon the surfaceof the,k

cigarettes.

After a short time, the vibration ceases, the` cigarettes having rotated to the required position and the conveyor moves on one stage so that the brush 36 delivers the cigarettes to a grooved plate 43 from which theyrnay be taken to the packing machine.

The brush 36 is provided with a pusher 44 Ycarried on springs into contact withblades or the like, and the plate may be given a vibratory movement similar to that used on jigger conveyors in order to cause the cigarettes to rotate in the required direction. v
