Device for the production of tobacco rolls

The invention has a tobacco rolling device, in particular for cigars, to the subject. In particular, it relates to the construction and operation of the roller cloth or barides (Chianti band) of such a device.

The aim of the present invention is to provide a method and a device to make a rolling table at higher speeds than was previously possible operate by reciprocating the feed roller is avoided.

Furthermore, a rolling table is to be created in which a plurality of feed rollers is used so that the

9 0 9830 / Ö11S

Training of the pocket for the subsequent tobacco wrap and their detection by the feed roller immediately after the delivery of the preceding bundle of tobacco occurs without having to wait for the return movement of the feed roller.

Further, a Rollierungsband is to be created for a Rollierungstisch * has which feed rollers which move in the forward or roll direction only between the w Rollierungsband and the Rollierungstisch and return under the Rollierungstisch.

Furthermore, a device is to be created through which the feed rollers are guided and operated so that their. 'Eliminated back and forth movement under the rolling belt will allow the speed of the rolled tobacco rolls engaging end part of the device for production is enlarged by cigars without increasing the rolling speed of the tobacco wrap would be required.

"■ ■ Details of the present invention emerge from the The following description of an embodiment based on the figures.

Fig. 1 shows a side elevation, partly in section, of that of the invention Tobacco rolling device.

Fig. 2 shows a plan view of the device according to the invention ^{do £} '. 909830 / 011S

Fig. 3 shows a sectional view along the line 3-3 of FIG.

Four vertical supports 12 are fastened to the base plate 10, each of which has an arm I ¹ + on which the floor of the roller table 16 provided with chambers rests. The table 1.6 has an upper surface 18 "which is connected by side parts to a floor 22 at a certain distance in such a way that an inner vacuum chamber 20 is formed. The vacuum chamber 20 is connected to a suction device (not shown) via a line 2h. The upper surface 18 of the table 16 has openings 26 through which the suction of the chamber 20 reaches openings 28 of the rolling chair or belt 30.

The rear carrier 12 have lugs 32 to which the bearings 3 ^ are attached, in which the shaft 36 of the gear is mounted. The gear shaft 38 is rotatably mounted in a bearing in the frame of the device and in a bearing arm 39 ^{which is attached to the} front end of the vacuum chamber 20. ^{The gears 1} K) and M-2 are keyed on the shafts 36 and 38, around which the two chains Mt · run at a distance from one another.

Two feed rollers * + 6, 4-8 each sit on a horizontally extending shaft 60, each of which is rotatably seated in two lugs 50, 52 located at a distance from one another, which are attached to two points of the chains Mf, k $ so that they are diametrically opposed at a distance from one another (180 °), as can be seen from FIG. The shaft 36 is

909830/01 15

an idle shaft, while shaft 38 is over with the main drive gears 5 56 and 58 connected to the device is driven synchronously. Each shaft 60 carrying a feed roller carries at its outer end two rollers 6 * +, which to engage in longitudinal guides 66 to the Feed rollers ^ 6, ^ + 8 neatly over the roller table respectively. The guides 66 are carried by holders 68, which are attached to the supports 12.

The front end of the rolling tape 30 is anchored to a resting shaft 70 which is carried by the arm 72 on the floor plate 10. The rear end of the rolling cloth is fastened in a take-up reel 7k , which is held by arms 76o The take-up reel pulls the rolling tape back in a known manner as soon as a rolled tobacco roll is delivered from the bag for world heritage transport * The rolling tape runs over an idle roller 78, which is held in a projection 80 of the bottom of the filling chamber 82. .

"■■■ - ..

The horizontally extending filling chamber 82 can be designed as shown in FIG. 1 of US Pat. No. 2,021,652 to Halstead and a compression piston 8 ¹ +, which is actuated with the aid of a device (not shown), a knife 86 for cutting off a Filling quantity and a transfer device 88 with an ejection piston 90. The transfer device 88 is rotatably mounted in a holding arm 92 which is connected to a sliding device 9k , which in turn can slide on a resting shaft 96.

909830/0115

The device 88 and its operation is in that mentioned U.S. Patent 2,021,652 is described in detail. In the present Device, the transfer device 88 has a dual function, namely to assist in formation of the pocket P and the transfer of the filling quantity to the Bag. ■

At the point in time at which the tobacco charge C is deposited on the rolling belt, the roller 78 holds the rolling belt 30 at a height such that the advancing feed roller 46 can grip the rolling belt above and behind the pocket P formed. As the chain continues to move over the roller burnishing table , the rollers 6k of the feed roller engage the guide 66 holding the feed roller down. The feed roller k6 thus moves over the table and in the process rolls up the tobacco roll in a known manner. In the direction of its front end or its delivery end, the roller burnishing table inclines downwards at 98, while the feed roller continues to move horizontally as a result of the guide 66 and the arrangement of the shaft 38. As a result, the pocket P is opened and the tobacco roll B is transferred to the waiting transport gripper 100. At the same time, the winding mechanism of the roll 76 can cause the pocket to be pulled out of the rolling tape. As soon as the arm 102 of the conveyor gripper 100 moves in the direction of the arrow, the clamping jaw 10 ¹ + of the transmitter 100 can close under the action of the spring 106 and the finger I08 is withdrawn from the adjustable stop 110 at rest. As soon as the

909830/0 11

Feed roller * + 6 reaches the position of the feed roller k8 shown in the drawing, the feed roller * t8 is ready to begin its path over the roller burnishing table. The chain Mt therefore makes half a revolution with each working cycle.
