This invention relates to cigar machines, and more particularly cigar machines having a device for winding wrappers about tobacco fillers to produce cigars, cigarillos or cigarettes. In such manufacture, tobacco particles, tobacco dust and other dust as well as adhesive are likely to adhere to the operating parts of the machine and make them dirty, particularly if mechanical means is used to transfer the finished product from the rolling device. In the operation of such a device the tobacco filler is placed upon an apron on a rolling table and a pasted binder or Wrapper, previously placed upon said apron, is wound about said tobacco filler. The finished product thus obtained is delivered by the apron to a movable carrier at the front end of the rolling table. Thereby dust and other tobacco particles will be pressed out of the ends of the cigar and adhere to the rolling apron, Such particles are likely to adhere to the subsequent product when winding same and, furthermore, they will make the machine dirty. It is a main object of the invention to remove the said drawbacks.

In the drawings:

Fig. 1 is a plan view of an embodiment of the L improved cigar machine;

Fig. 2 is an elevational end view of the machine on the line II1I of Fig. 1;

Fig. 3 is an elevational side view on theiline III-III of Fig. 1; and

Fig. 4 is a similar view on the line IV--IV of Fig. 1, some parts being omitted for clarity.

Fig. 5 is a sectional view on an enlarged scale, taken on the line V-V of Fig. 1, certain parts being omitted for simplicity of illustration.

Referring to the drawings, the filler tobacco is introduced by means of a conveyor I into a tobacco portioning device 2, from which the tobacco portions are transferred into a pocket 9 formed by a rolling apron 4, placed on a rolling table 3.

upon a leaf cutting device I which has a suction die 6. The cutting is effected in usual manner by means of two cutting rollers 42 which are rotatably journalled on an arm 43 which projects laterally from a slide 44. The slide is reciprocated by a shaft driven by means (not shown) of well known character. The cut wrapper is removed from the cutting die by means of a pneumatically acting wrapper carrier 8 and supplied to the perforated rolling apron 4. .The wrapper carrier 8 is mounted on a hollow suction arm 45 which has a toothed segment 46.

Said

segment meshes with a rack 41 which is reciprocated by the shaft I9. The perforations ofthe rolling apron 4 communicate with perforations in the rolling table 3 the inner portion of which forms a suction chamber connected to a suction source. The suction within said chamber is automatically interrupted every time the rolling operation is finished-and. is restored when another wrapper is placed upon the rolling apron. An adhesive is supplied to the front edge of the wrapper placed upon the apron. This supply is effected by means of a bar II which is movable between a paste container I 0 and the rolling table. In the position above the rolling table the bar II is lowered into engagement with the wrapper. Thereafter the tobacco filler supplied to the pocket 9 is wrapped up in the wrapper in well known manner. The Wound product is expelled at the front edge l2 of the rolling table, where it drops into a holder I 3 which is mounted on a rotatably journalled shaft l4. An arm I5 is secured to the shaft l4 and is pivoted to a rod 16 which is pivotally connected to a bell crank lever l8, turnably journalled on a shaft l1. The bell crank lever I8 is actuated by a cam 20 which is keyed to the continuously revolving shaft l9. By this mechanism the holder I3 is swung upwards and thereby away from the front of the rolling table 3 immediately after having received the Wound cigar A from the apron. Thereby the cigar is moved transversely past two stationary cutters 2|, whereby its ends are cut oil in transit, and thereafter the cut cigar drops into a channel 22. A suction conduit 23 is connected to the channel 22 land is widened towards its delivery end 24, where it opens into a delivery chamber 25. Thereby the velocity of the air current is decreased when flowing towards the chamber 25, so that the velocity of travel of the cigar is also decreased, so as to obviate damages on same when thrown into the chamber 25. Furthermore, the conduit has a flattened cross-sectional shape so as to obviate sticking of the cigars in the bends or curvatures of the conduit. During the travel of the cigar towards and into the chamber 25 its surface and ends are cleaned by removing dust therefrom by means of the air currents passing through the conduit 23. Furthermore, adhesive on the surface of the cigar is readily dried by such air current. The bottom of the chamber 25 consists of a closure 26 secured to a shaft 21 to which is also secured an arm 28. By means of a rod 29, a bell crank lever 3|, turnably journalled on a shaft 30, a rod 32, a bell crank lever 33, turnably journalled on the shaft l9, and a cam 34 secured to the shaft I9 the arm 28 can swing the closure 26 downwards from its closed position, as shown in Fig. 5 into its open position, as shown in Fig. 3, and thereby the cigar will drop into a collector 50 which is secured to the machine frame. To obtain the pneumatic transport within the conduit 23 a suction conduit 35 is connected to the chamber 25. Said conduit 35 is conveniently connected to the same suction source 80 as the suction chamber of the rolling table 3. When the closure 26 is opened the suction effect within the delivery chamber 25 should have finished. To this end, a flap 36 is arranged within the chamber '25 and connected to a rod 31 which is moved. up "and down by means of a bell crank lever 38, turnably ing means and said closure device, and automatic mechanical means to first operate said delivery means and open said valve and thereafter to shut said valve and open said closure device.

2. A cigar machine having a device for rolling a tobacco filler into a wrapper, means forming a flattened suction channel, means for deliverin the finished product to said channel, means for journalled on the shaft, a rod 39, a bell crank lever 40, turnably journalled on the shaft, and a cam 4| secured to the shaft. The suction is opened when the flap 36 is moved downwards from its closed position (Fig. 2) to open communication between chamber 2 5 and suction conduit 35.

Having thus described my invention I claim:

1. A cigar machine having a device for rolling a tobacco filler into a wrapper, means forming a suction channel, means for delivering the finished product to said channel, means for creating suction in said channel, a closure device for discharging said product from said channel, a valve in said channel between said suction-creatcreating suction in said channel, a closure device for discharging said product from said channel, a valve in said channel between said suctioncreating means and said closure device, and automatic mechanical means to first operate said delivery means and open said valve and thereafter to shut said valve and open said closure device.

3. A'cigar machine having a device for rolling 'a tobacco filler into a wrapper, means forming a flattened suction channel, means for delivering the finished product to said channel, means for creating'suction in said channel, a closure device for discharging said product from said channel, a valve in said channel between said suctioncreating means and said closure device, and'automatic mechanical means to first operate said delivery means and open said valve and thereafter to shut said valve and open said closure device, said channel forming means diverging in a direction towards said closure device.
