Automatic device for packing cigarettes in packets of cigarettes

The present invention relates to a cigarette packing machine, especially for processing the cigarettes in cigarette packs, with which, of loose Starting out from cigarettes, after a series of processing— phases, ready-sealed cigarette packs can be obtained, with the defective packs already from excluded from the start.

There are already known machines for the automatic packaging of cigarettes in which the cigarettes pass through of the individual work-up phases are arranged with their longitudinal axis in the gate push direction, while the off several layers of packaging material lying on top of one another

existing wrapping either directly over the cigarettes! «) r is placed so that the cigarettes act as the core serve, or else, the bottom of the pack also being completed is put around a solid core, which consists of a tubular element into which the cigarettes be inserted in the direction of their own axis, t that they push against the bottom of the packaging shell and they pull it off the solid core.

The cigarettes are therefore constantly stressed in their longitudinal direction from the tip, because during all of them Work-up phases, both in the course of the pack production and when simply transferring one Preparation phase to the other, the cigarettes are exposed to such axial loads that affect their quality In particular, the cigarette paper is folded and crumpled and the tobacco is inside the cigarette paper loses its huddled and compact arrangement. In addition, the operating speeds and accordingly the unit capacities' of these machines, due to the time required for the individual work-up phases as well as the considerable, fluctuating movements subjected Crowds, or for any other reason, often insufficient and limited to each pail

The present invention has set itself the task to "eliminate the disadvantages mentioned with one gate direction," "at which the cigarettes during the preparation in cigarette packs, are always arranged so that axial loads be avoided. Still with the intent not to put the cigarettes in particular at the top claim, in the device according to the invention, the individual cigarette groups, each a cigarette pack should form, constantly between surfaces, or jj with the help of gripping means and support means in general, held together, protected and guided. The groups of cigarettes therefore remain fixed during all operations together and the individual cigarettes are already there in the same position in which they are then arranged in the packs »

Another object of the present invention is a device for packing cigarettes in cigarette packers gen available, their operating speed and work fee per unit of time is significantly higher than with the machines normally used in this field.

In the middle of the longitudinal extension of the lever 55, the common axis of a rotatable pair of knobs 58 and 59 is attached. This pair of knuckles works together with a cam 6u fastened on the v / elle 33, through which a double eccentric guide is given, and Λ

a front guide 61 for the Holle 58 and a roundabout- Catch guide 62 for the Holle 59, on top is the lever 55 via a hinge plate 63 at 64 to a Locking b5 hinged. With this lock the two are aligned and "on both sides of the barrier arranged sections, of a horizontal rod-shaped part 66 firmly connected, which accordingly runs parallel to the axis 12. During the rotation of the shaft 33 and thus the cam 6ü the lever 55 performs a pendulum movement about its pivot axis 57 "so that the rod-shaped Organ 66 performs a back and forth movement on its own axis. The longitudinal movement of the rod 66 is controlled by the Engagement of the fiollen 67 limited, which rotate in the longitudinal guide 69 about inre on the lock 65 fastened pin 68.

In particular, a second rod-shaped element 66 is provided, which is arranged in parallel with part 66 is and also performs a back and forth movement. The cam 60a is designed, however, that the movements of the parts 66 and 66a with a certain phase shift, as in the following in more detail is described.

On the rod 66 is the support surface 70 of a first overpass a element there 71 and on the rod 66a the wing 70a of a second transfer element 71a which cooperates with part 71 · The two transfer elements 71 and 71a have two to each other at their end parallel receiving surfaces 72 and 72a, which are essentially spaced from one another by the length of the larger side of a pack of cigarettes. Other transfer elements, Sliders and companion elements are similarly supported on rods 66 and 66a.

In other words, the cam disks 60 and 60a are such profiled that they work with a certain phase shift. In particular, the guide elements move together until they get close to the pretty the rods 66 and 66a arrive. When you have reached these end points, a bar begins to run forward and as a result of this phase shift, the pairs of gripping elements open by a small amount, which is why the Removal and dispensing processes of the cigarette packs, which are described in more detail below, can take place. the Waves 49 »53 and 54 take care of the transmission of all Movements necessary for the successive, separate workstations for the folding of the Packaging material are required, which stations in their entirety with 78, 79 and Θ0 (see Fig. 1) be f are drawn and in which the various cigarette packagings occur.

These openings are therefore at regular intervals with the outlet opening 278 in the .ISlide sleeve connected so that the openings 255a in the fork likewise at regular intervals across the interior of the hollow rod 256 can be connected to the suction device.

It is therefore clear in what way an induced draft can be created at the openings 255a when the Fork is at the outer end of its upward stroke, which suction has such an effect that the Distribution device coming label 254 can be held on the fork. Will the negative pressure in the openings 255a is maintained, then the label is maintained during the downward stroke of the fork 255 as long held until the legs of the fork have positioned themselves over the transverse feed path of the cigarette pack. At this moment the suction from the openings 255a stops and the label is released just then,

when the cigarette pack between the fork legs passes through it and is taken away by the pack.

The cigarette pack is directed from pusher 236 through fork 255 and then into conduit 282, and after it has overtaken the spring-loaded shut-off wedges 203, even the slightest backward movement is the Pack excluded.

The above-mentioned label distribution device 254 can be designed in exactly the same way as the above-described 172. It therefore consists of a funnel 284 (Pig.8), from the bottom of which the labels 254 one after the other and at regular time intervals, over a cylindrical section 285, which is both accessible and movable to and fro. The surface of this section 285 is connected at regular time intervals to a suction device via an alternately moving slide or slide sleeve device 286. The labels sucked off by means of a vacuum are directed to a gumming unit, which consists of a tub 287 in which the gumming agent is contained.

This tub can be swiveled around a cross tube ,

and inside a guader roller 288 is immersed, which is mounted on the tub and the gumming liquid on a counter roller, not shown the surface of the passing labels transfers.

At the outlet from the machine described up to now you can the cigarette packets from the same pusher 236 eventually to drying stations for drying the gummed spots are directed. For this reason, the arrangement of another device is advantageous, such as they are described in German Patent No. (Patent Application Hr.

Since the labels are removed by a vacuum generated on the surface of the cylinder section 174, which is produced at regular intervals, it is sufficient to interrupt the connection with the device for generating the vacuum for the cycle corresponding to the label removal, so that the label at Passing the gap is not deducted. Since the intermittent connection is now established via a distributor with a movable slide, it is sufficient to block the suction line 303 during a work cycle with the aid of the closure element 304 (Pig. 8). In addition, the tub, pushed by an arm 305 "can be pivoted about its own axis 181" so that the gumming roller is separated from the counter roller 183 in order to avoid unnecessary feeding of gumming material during the holding phase.

Since the delivery of the small labels or sealing marks is carried out in the same way as for the large labels.
