Field of the Invention The present invention relates to a device for supplying groups of cigarettes to a cigarette packing machine. The groups of cigarettes are pushed, by at least two reciprocating slide members, into the compartments of a reciprocating receptacle, from which they are pushed into the packing machine or the like.

The object of the invention is to transfer cigarettes from the so-called magazine to a cigarette packing machine. More particularly, the invention is intended for use with cigarette packing machines in which a revolving part containing pockets for receiving one group of cigarettes per pocket, is connected at the outlet side of the cigarette magazine.

2. Prior Art In the known devices of this type, the groups of cigarettes are pushed directly from the magazine into the pockets of the revolving part. The device operates with a reciprocating slide member, which enters the magazine. As a result, the device is not capable of high production as the cigarettes in the magazine move very slowly into the discharge position.

SUMMARY OF THE INVENTION The object of the invention is to render more efficient the formation and discharge of groups of cigarettes from a magazine to a part of a cigarette packing machine, more particularly, to a revolving part provided with pockets or compartments.

According to the invention, this problem is solved by providing a push rod driven in synchronism with two slide members but in double time. The push rod is designed to push out the groups of cigarettes introduced by the slide members into the compartments of the reciprocating receptacle. The push rod pushes the cigarettes from one compartment while the other compartment is being filled.

The reciprocating receptacle enables the formed groups of cigarettes to be pushed much more rapidly into the pockets of the subsequent rotating part.

According to another feature of the invention, the cigarettes received by the reciprocating receptacle are pressed together in the compartments of the receptacle. This embodiment of the invention is particularly useful if the successive devices on the cigarette machine are not provided with means for pressing together the group of cigarettes.

Other features of the invention will be made apparent from the following detailed description of the embodiment represented in the accompanying drawings in which:

DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention relates to the transferral of cigarettes 10, in the form of groups of cigarettes 12, from a magazine 11 to a cigarette packing machine, more particularly to a revolving part 13 provided with compartments or pockets 14 for receiving the group of cigarettes 12. The magazine 11 is provided on its base with two outlets l5 and 16 for discharging the cigarettes 10. The

outlets

15 and 16 consist ofa plurality of shafts 18, separated by shaft walls 17. A row of cigarettes 10, disposed on top of each other, is kept ready in each shaft 18.

The groups of cigarettes 12 are removed at the lower end of the

outlets

15 and 16 by the

slide members

19 and 20. The

slide members

19 and 20 introduce the fingers 21 into the individual shafts 18 of the outlets l5 and 16 and push out a group, consisting, for example, of two cigarettes 10 arranged one above the other. The

slide members

19 and 20 are driven in a reciprocating manner.

The groups of cigarettes 12, composed and removed by the

slide members

19 and 20, are pushed into a reciprocating receptacle 22, or alternatively into

compartment

23 or 24 of this reciprocating receptacle 22. The reciprocating receptacle 22 may be moved in a reciprocating manner in the direction of the arrow 25 in front of the

outlets

15 and 16 of the magazine 11 or in front of the

orifices

26 and 27. The end position of the reciprocating receptacle 22 is such that one of the

compartments

23 or 24 is always in front of either

outlet

15 or 16. It is thus always possible to insert a group of cigarettes 12 in these end positions.

The cigarette groups 12 are removed from the reciprocating receptacle 22 by a push rod 28. The reciprocating push rod 28 is arranged between the two

slide members

19 and 20. The relative position of the

compartments

23 and 24 of the reciprocating receptacle 22 is such that, in the end positions, one or other of the filled

compartments

23 and 24, is always in the plane of motion of the push rod 28. In the embodiment shown, the groups of cigarettes 12 are pushed by the push rod 28 directly into the pocket 14 of the revolving part 13.

The push rod 28 is operated in synchronism with the movements of the reciprocating receptacle 22 and the

slide members

19 and 20 to empty the filled

compartment

23 or 24. The push rod 28 is thus driven at double the speed of each of the

slide members

19 and 20.

The construction of the reciprocating receptacle 22 may be such that the groups of cigarettes 12 introduced into the

compartments

23 and 24 of the receptacle 22, are pressed together. This is advantageous for the remaining part of the packing process. FIGS. 4 and 5 show an embodiment of this reciprocating receptacle 22. The receptacle 22 shown in the embodiment consists of two parts, an upper holder 29, and a lower holder 30. The two holders together form the bottom walls 31 and the upper walls 32 of

compartments

23 and 24. Two

side walls

33 and 34, laterally limiting the compartments, are integral with the

holders

29 and 30. The

holders

29 and 30, and thus the walls 31. .34, are adapted to move relative to each other. Accordingly, in the embodiment shown, both the height and the width of the

compartments

23 and 24 may be increased or reduced. For'this reason, the free ends of the

side walls

33 and 34 are supported on the inclined surface 35 of the

opposite holder

29 or 30. Displacement of the

holders

29 and 30 relative to each other in a transverse direction also results in a displacement in height.

In the embodiment represented (see also FIGS. 6 8), the

holders

29 and 30 are supported and driven by

swivellable guides

36 and 37 or 38. The guide 37 merely serves as a support, while the

guides

36 and 38 transmit a reciprocating drive to the

holders

29 and 30, which produces a relative movement of the two

holders

29 and 30, thus broadening and narrowing the compartments, together with a simultaneous transverse movement in the direction of the arrow 25. The two holders are connected together by means of

parallelogram guides

39 and 40.

FIG. 4 shows the open position of compartments 23- and 24, and FIG. 5 the pressing position of the same.

FIGS. 6 8 provide a detailed view of a drive mechanism for a device provided with a reciprocating receptacle according to FIGS. 4 and 5. In this case, the

slide members

19 and 20, the push rod 28, and the reciprocating receptacle 22, are driven by a common shaft 41. A gear wheel 42 is supported on this shaft. The gear wheel 42 meshes with a (smaller) gear wheel 43. The gear wheel 43 drives a crank 44, which has connected thereto, a swivel arm 45 for transmitting a reciprocating drive to the push rod 28. To this end, the-push rod 28 is provided with a rearwardly directed projection 46, on which the swivel arm 45 catches.

The two

slide members

19 and 20 are also driven by the main shaft 41 via a crank assembly. Crank arms 47, which act on a swivel arm 48, are connected to each end of the main shaft 41. The movement of the crank arms is transmitted via a shaft end 49 to a guide 50 connected to the

slide member

19 or 20. The guide 50 is connected via an oblong hole guide 51 to a sliding carriage 52 supporting the

slide member

19 or 20.

The drive for the reciprocating receptacle 22 and/or for its

holders

29 and 30, is provided by cup-shaped earns 53, arranged at the end of the main shaft 41. The

guides

36 and 38 connected to the

holders

29 and 30, are provided with tread rollers 54, which move in a groove 55 of the cup-shaped cam 53. When the two cup-shapedv cams 53 rotate (as a result of the rotation of the main shaft 41), the

guides

36 and 38 are driven in a reciprocating movement, which causes the receptacle 22 to move in a reciprocating manner. The design of the cup-shaped cams and/or their grooves 55 is such that, when the receptacle 22 moves in a reciprocating manner, the

holders

29 and 30 move relative to each other, and as a result the cigarettes are squeezed together in the

compartments

23 and 24.

The constructional form of the above-mentioned drive means for the receptacle 22, producing a controlled movement of the

holders

29 and 30 relative to each other, merely represents a preferred embodiment. The movements may also be controlled in other ways, for example, by guiding a holder by means of a guide pulley in a control pattern or slot.

FIG. 9 shows another, much simplified embodiment of a receptacle 22 comprising

compartments

23 and 24 pressing together the groups of cigarettes 12. The

compartments

23 and 24 are provided with a movable side wall 56, which is acted on during the cross movement of the receptacle 22. In the embodiment shown, the side wall 56 is disposed on a piston pin 57, which may be displaced from without against the pressure of a pressure spring 58. The piston pin 57 and thus the side wall 56 is acted on by a stop 59, which effects a reciprocating cross movement with the receptacle. This movement of the stops 59 is controlled in such a manner that the piston pin 57 is acted on during the movement of the receptacle, i.e., between the end positions. The side walls 56 are not acted on by the stops 59 in the end positions, so that the groups of cigarettes 12 can be pushed in and out without pressure.
