11 Claims, (Cl. 198-25) -This invention relates to a delivery device for cigarette making machines, comprising a longithe grooves of which cigarettes are laterally inserted.

In machines which operate at a high speed, known delivery devices readily lead to disturbances, and even the lateral insertion into the drum is unable, in itself, to provide a remedy, because the friction between the inserting device and the cigarettes which are being fed is excessive. The present invention obviates this disadvantage by the fact that the inserting device, moved laterally in timed relation with the rotation of the drum, possesses a component of motion in the direction of feed of the cigarettes.

The accompanying drawing shows by way of example two constructions according to the invention.

Figures 1, 2 and 3 show a longitudinal section,

a plan view, and a side view respectively, of one construction, and

Figure 4 is a plan view showing a modified construction.

The cigarette rod a is carried in known manner through the cutting tube t in which the cigarettes are cut to the required length. The cigarettes then pass through a guiding tube 0 and between two conveying belts veying belt d ends or bands (1 and e. The conjust in front of a grooved drum 1. The pulleys d and it over which the belt it runs may be made concave so that the belt is arched as shown in Figure 3. The lower belt e passes over a roller 6 then beneath the cigarettes and along to the grooved drum j, and is carried in front of this drum over two rollers e and c The drum f itself, which continuously or intermittently rotates on a shaft 9 is driven in any desired manner, not shown in the drawing. The cigarettes that arrive beside the drum f are moved into the grooves h, of the drum, in the case of the construction according to Figures 1 to 3, by means of two cams i and i which rotate in the same direction and with the same speed. As shown in Figures 2 and 3 there is suflicient space between the peripheries of these cams and the drum f for the cigarettes. When the cams rotate, they push the cigarette lying beside them, away from the belt as shown more particularly in Figure 3 e and into the groove of the A protecting metal sheet is prevents the cigarette from falling out of the drum. The drum has an annular groove m which extends to of the grooves h an ping finger n. This the bottoms d in which engages a stripfinger presses the cigarettes out of the grooves h so that they fall on to a conveying belt 0, which then conveys them forward in the ordinary way. The conveying belt 0 passes over a roller 0 and is driven in a manner not shown in the drawing. 1

The cigarettes will assume different positions in their longitudinal direction on the drum f. In order to align them so that they can be delivered in the correct position to the band 0, a dressing device is provided in the form of a swash plate 10 or inclined disc p. The hub p of the said disc is fast on a hollow stub shaft q which is journalled on a pin q The latter is fast on a pin T which, for example, is rigidly mounted in the bearing r that is to say, it is not rotatable in the machine frame. The pin q is connected by means of a universal joint s to a shaft s which engages in the shaft g and is connected therewith for rotation in common. 0n the disc p are provided arms 11 which'engage' slots f in the drum f. The disc p consequently rotates about the pin 11 when, on the rotation of the drum 1, it is driven due to coupling by means of the universal Joint with the driving shaft q of said joint. At the same time, the arms p make a reciprocating movement in the slots 1 and on entering the slots, as will be seen in the case of the lowermost cigarette, they push the latter into the correct position within the groove in which it can be delivered to the conveyor band 0. I

Figure 4 shows a second constructional form of the invention. In this case, instead of the rotating cams i and i there is provided a parallel crank device comprising a pusher t carrying at its front end a facing member t which engages the cigarettes, the pusher t being connected to the two crank-pins c and v The crank-pins are driven by two shafts w and w in a manner not shown in the drawing. In operation the pusher t will, during its movement towards the drum and in the direction of the cigarettes, engage the clgarette, press it into the drum, and simultaneously make with it a short movement in the direction of the cigarette, the member t braking the movement of the cigarette. The plate 1! then moves from the cigarette and returns into its initial position.

For the same reason as that for which the facingmember t is provided, the cams i and i (Figures 1 to 3) may also be provided with a braking facing i The conveying belts d and e are advantageously caused in a known manner to move with a velocity somewhat greater than that of the cigarette rod in order that the cigarettes may be spaced apart during their conveyance on these belts, and that consequently there may be an interval sufiicient to prevent on the insertion of the foremost cigarette, the succeeding one from being injured or carried along therewith. As a pushing-in device there might also be employed a belt or band provided with fingers and constantly running around the drum.

I claim:-

1. A delivery device for cigarette rod machines comprising, in combination. a rotating drum provided with grooves adapted to receive the 01g.- arettes, means for delivering said cigarettes ardrum and adapted to deliver the cigarettes by the side of the drum and rotatable cams arranged laterally of the drum into said grooves.

2. A delivery device for cigarette rod machines comprising, in combination, a rotating drum produce the feedirig 3. Delivery mechanism for cigarette making the grooves through the line of feed of the cigarettes as the drum rotates.

- 4. A device according to claim 3, in which two conveying belts are provided which engage the cigarettes between them at the outlet of the machine. one of the belts passing beneath the inserting device and extending across the length of the drum.

5. A device according to claim 3, in which the inserting device comprises rotatable cams.

6. A device according to claim 3, in which the inserting device comprises a pusher, and a crank driving device for actuating the pusher.

7. A device according to claim 3, in which the inserting device comprises rotatable cams and a braking facing which reduces the feeding velocity of the cigarettes.

8. A device according to claim 3, in which the inserting device comprises a pusher, a crank: driving device for actuating the pusher, and a braking facing which reduces the feeding velocity of the cigarettes.

9. A device according to claim 3, in which the d um has a greater length than the cigarette, and in which an inclined disc is provided which rotates about an axis inclined to the axis of the drum for aligning the cigarettes on the drum.

10. A device according to claim 3,. in which the said disc being provided with arms which project into the grooves through slots in the drum.

' 11. A device according to claim 3, in which the drum has a greater length than the cigarette, and in which an inclined disc is provided which rotates about an axis inclined to the axis of the drum for aligning the cigarettes on the drum, said disc being driven by being coupled to the shaft of the drum by means of a universal joint.
