- In Sweden December 23, I. 1932 7 Claims. (01. 226 -5 .Machines for: packaging; cigarettes previously have: been proposed, in which the cigarettes through. aspecialL-shaking. device are caused to descend-from. a. magazine into two 1 sets of distributingi partitions, from which the cigarettes in a-: s u itable:-number are then. ej ected' alternately m order to -be-introduced into boxes, or the like. The said-sets of partitions, however, were. stav tionary and for the transferring of the cigarettes from the saidsets of partitions'to a packaging place-common to the same, in which they are pushed into the ,box the machine is provided- With a: reciprocatedslide provided with two. compressor chambers. which alternately are placedin front of the sets of' partitions respectivelyand a piston common to thesame, which pusheszthesets of cigarettes from the said chama bers and: further intothe. boxes.

Bars 11 and 12 have oblique positions which are so adapted, that, as the partitions are in their left position, shown in Fig. 1, the walls of the left set of partitions are parallel to each other and the distance between the same is the greatest one alongthe whole heightv of the partitions. Consequently, the cigarettes may easily descend from the magazine to the bottom of the partitions. When, however, the walls of the set of partitions now in question have been moved to their right positionpshown in Fig. 2, in which position the cigarettes are ejected from the partitions, thewalls converge downwards, so that the cigarettes are moved together and constitute rows located closer to each other, which is an advantage regarding the transmitting of the cigarettes intol the boxes. The case is quite the same at the'right set of partitions, in which the walls are parallel to' each other in the position shown in Fig. 2 and converge downwards in the position shown in Fig. 1.

While the partition walls are moved'betwe'en the stated positions, the top ends of walls act upon the cigarettes located at'the bottom of the magazine and effect a certain movement of the same, which facilitatesthe entrance of the cigarettes into the partitions. Besides, a certain movement of the partition walls relatively to each other takes place during the shifting of the same between thetwo positions stated-above which prevents in an effective manner the cigarettes from clogging in the" celerates still more 'the falling of the cigarettes into the partitions. l 1

Owing to'their connection; with the outer par tition' walls 1* the plates 7, forming parts of the bottom wall of the magazine, are moved rapidly upwards" and downwards and arelialso' reciprocatedhorizontally, which results in the cigarettes moving inwards towardsthe partition'sets and in a sufiicien't amount of ciga rettes being always provided in the space above the said groups. The top edges of the partition walls are located in faces slanting inwards; Owing to this arrangement the'top ends of thepartition walls and the uppermost cigarettes in 'the partitions constitute oblique surfaces, on which the cigarettes slide downwards and are distributed substantially uniformly above 7 1 manner stated above whereupon the pistons the partitions. g i

For the ejecting of the cigarettes from the partitions the machine is provided with pistons 21. It is assumed, that in the present'cas'e twentycigarettes are packaged into each box and in three rows. For this reason the pistons 21 are disposed in three rows, as shown in Figs. 1 and 2. As perceived from Fig. 1, the. partitions have an oblique position downwards toward the left hand side, while the partitions in Fig. 2 have an oblique position downward toward the right hand side. Owing to thisfact, it is necessary to change the groups of pistons 21, so that the pistons are adjustedin accordance with the different slanting positions of the partitions. For this purpose the pistons 21 are provided on three carriers 22, 23 and 24 one for each horizontal row of pistons. The lowermost carrier 22 is fixed to a slide 25, which is movable in a guide 26, Fig. 4. Slide 25 is reciprocated by an arm 28, which is pivoted at 2'7 and by means of a rollerengages the groove of a disc.29.fixed to the shaft 17. The said arm 28 is fork shaped and embraces a roller 28 on the slide 25,"Fig. 4.

The slides 23 and 24 on the other hand are slideable laterally and are held in adjusted positions by a' plate spring fixed'to the carrier by means of a screwbolt 30. I For moving the carriers 23 and 24 together with their pistons into the two differentlateral positions shown in Figs. 1 and 2,

the machine is provided with two fore arms or shifters 32, 33, which act upon the carriers 23 and 24 respectively, and two rear arms or shiftem; 34, .35 which act upon the carriers 24 and 23 respectively in opposite directions. As the carrier 23 is shifted toward the right hand side, Fig. 3, the carrier 24 is shifted toward the left hand side, Figs. 3 and 4, and vice versa. The shifter 32 of the front pair is journaled on a shaft 36 and from the hub of the same an arm 37 extends, providedwith a toothed sector 38, which meshes with a toothed sector 390i anarm 40 on the hub-of'the shifter 33, journaled on" a shaft 411- 'In the same manner the shifter 34 ofthe rear pair is connected to the shifter 35 by means of arms 42' and 43 provided with toothed sectors 44 and 45 respectively. Shifter 33 is pro-- videdwith an arm 46, to which a fork shaped.

link 47 is connected, which embraces a die 4850a the cam shaft and is guided by the same. I said link is forced with its roller 49 against'a cam disc 50 on the said shaft by a spring (not. shown). The shifter 35 of the rear pair is acted upon in the same manner by a cam disc 51,1

Fig. 4, a link 52 and an arm- 53'connected with the shifter 35. The cam discs 50 and 51 are so adjusted, that, as the shifters" 32 and 33-of the fore pair are moved toward theright and the left'hand sides respectively the shifters 34 and- 35 of the rear pair are moved toward the left and the right hand sides respectively and in this mannerthe positions of the carriers 23 and 24 toward'the right hand side. The shifting of the carriers is effected, as the slide 25 isin its inner position, shown in Fig. 5. The shifters may be so arranged that they positively hold the car riers in their different operative positions.

As the pistons 21 have ejected the cigarettes in the right set of partitions, Fig. 1, the s'ets of partitions are transmitted to the position shown" in Fig. 2 and the pistons 21 are shifted in the eject the cigarettes collected in theleft set of partitions, while cigarettes are gathered at the bottom -of the right set of partitions; In this manner cigarettes are ejected from the sets of partitions alternately and are then further transported into the boxes or covers;

If, as shown in Figs. 1 and 2, the cigarettes are packaged with seven cigarettes in the bottom and top rows and six cigarettes in the middle row, a small piece of sheet metal 62 isfixed to the partition walls 1 respectively, which preevents the seventh one-of the central row 'from being ejected. The shifting of the pistons of the central row will then be adapted hereto.

' The .machine for packing cigars and little cigars shown inFig. 6 is constructed regarding The its principal members in the same manner as the cigarette packaging machine described above. The machine shown in Fig. 6 is adapted to introduce into each cover ten cigars, distributed into two rows each containing five cigars and for that purpose the machine is provided with ten partitions. The ejecting pistons 56 are fixed to a slide 58 common to the same and movable in a guide. The said slide is reciprocated by means of a lever arm 59 and a groove disc on the cam shaft of the machine. Owing to the fact that the partitions of the machine are wide and only two rows ofcigars are ejected simultaneously from the partitions, the comparatively thin pistons may be adapted to act upon each two superposed cigars and maintain the positions shown in Fig. 6 also while ejecting cigars from the second set of partitions placed in front of the pistons.

The bottom plates 60 of the magazine are connected to the outermost partition walls 54 and suspended in links 61, so that the said plates during the operation of the machine impart to the cigars a motion forwarding the same downwards towards the partitions.

Owing to the fact that the cigarettes etc. may

- be transferred directly from the partitions to the boxes, the machine may be run with great velocity and consequently with great output.

The shown and described packaging machines may, evidently, be modified in some respects without exceeding the limits of the invention.

I claim:
