More specifically, the invention relates to cello-wrappers which rewrap packs of cigarettes in a cellophane sheet or other similar material.
These machines, to automatically cellowrap cigarette packs or other similar packs at a uniform rate, commonly use a so-called star wheel consisting of a certain number of radial pockets which are angularly equidistant from each other. This wheel is jog-operated by an intermittent motion mechanism. During the dwell between each ~og, the mouth of one of the radial pockets stops in alignment with the outlet of a coupling station to receive a cigarette pack together with a cellophane sheet which is engaged by the pack during transfer from the station outlet to the mouth of the ~
pocket. The appropriate folding of the cellophane sheet ;
round the pack will be completed in successive rotary ; steps of the star wheel. The packs to be cellowrapped must be fed in an orderly manner to the coupling station where each pack is engaged by transferring means, which lead it to the insertion into the relative _I_ ~ r ~L

The problem of the pack feed to the coupling station, and the one, concomitantly correlated with it, of the transfer of the pack, coupled to a relative sheet, in the mouth of the pocket which is stationary at the station outlet, is, generally speaking, solved, in the following two manners:

which is operatively aligned with the pocket and whose motion is in phase opposition in relation to the motion of the first plunger transferring means.
Both the above systems are inadequate when the speed or production rate of the cigarette packing machine exceeds certain values, considered so far as barrier values. For instance, in the first system as above, the descent by gravity of the packs from the feed hopper on the underlying chain conveyor gives rise to catching and transferring irregularities, when the cellowrapper operating rate exceeds a certain maximum safety value. In the second system, as above, there exist, under the same conditions, limitations to the rate itself due to the existence of idle times i .
between the linked phases of transfer, and to the fact that the motions of the two plunger transferring means cannot obviously exceed the limit of the interference or crossing of the respective strokes. In fact, the lifting plunger cannot lift a pack if the overlying transferring means has not completed its return stroke after the insertion of a previous pack into the mouth of the pocket aligned at a given moment with it.
Furthermore, the feeding belt cannot feed a new pack if the lifting plunger has not first completed its return or descent stroke. Finally, the cellophane .. . , , . .. , . , . - . .. .

These conditions of the correlated inter-calation of the motions of the lifting plunger and of the transferring plunger involve, in the respective alternate rectilinear motions, peaks of acceleration `~
ant relative forces of inertia, which, when the production rate exceeds certain limit values, are decidedly incompatible with the delicate nature of the packs to be cellowrapped~ in the case in point, the cigarette packs.
An ob3ect of this invention is to increase beyond predetermined limits the~production rate of a cellowrapping machine comprising a lifting plunger and a transferring plunger without exceeding the safety limits in the accelerations and in the forces . ~ .
of inertia, but by reducing the idle times of the in- -; tercalatet operations ant thereby increasing th,e number of operating cycles of the cellowrapping machine~per unit o~ time.

Su tantially, according to this invention, this purpose is achieved with a characteristic stacking-transferring device for cellowrapping machine, comprising stacking or lifting means and transferring or inserting means, in which the stacking means and the transferring means are susceptible of alternate motions intercalated between each other and are both provided with pack engaging means, capable of operatively inter-fering with the feed path of the packs arriving at the basis of the stacker, respectively with the path of the pack transfer from the top of the stack into the stacker, only in the respective active travels, while they are driven to accomplish the correlative return travels in conditions of substantial non-interference with the paths themselves, so that the lifting of a pack in the stack can be started by the stacking means, before the associated transferring means have completed their return travel, relating to the transfer of the previous pack, thus obtaining an increase of the cellowrapper rate of production, without exceeding critical values of acceleration in the alternating components of the device itself.
According to a further broad aspect of the present invention, there is provided a transferring and stacking device for a cigarette pack cellowrap machine having conveying means for delivering packs one after another to be cellowrapped and a step by step rotatably driven star wheel with a plurality of radial pockets receiving successive cigarette packs each with an asso-ciated cellophane sheet.

The first transferring means removes cigarette packs one after another from the conveying means and delivers each such pack to the bottom of the stack held by the retaining means causing the uppermost pack of the stack to rise. The second transferring means removes the uppermost pack from the stack and delivers such packs each with a sheet of cellophane to successive pockets of the star wheel.

The joint motion of the two lifting mechanisms 3 occurs in phase opposition in relation to the joint motion of the two transferring mechanisms 10. This means that, when forks 7 are at the lower stroke end the plungers 14 are at the outer stroke end, that is, towards the mouth of pocket 109.
As it will be clearly understood from the comparative examination of FIGURES 2 and 3, forks 7 can lift a pack without waiting for plungers 14 to complete their return stroke~ This is possible because the return stroke of plungers 14, similarly to that of :
forks 7, move outwardly away from one another or occurs in conditions of non-interference with the ~:~
