KAPPELER ETAL APPARATUS FOR FILLING PAPER CIGARETTE TUBES WITH TABACCO Filed Jan. 15,v 1964 5 Sheets-Sheet 3 Wyn r095 United States Patent 10 Claims. 32. 1311-70 This invention relates to an apparatus for filling paper cigarette tubes with tobacco, wherein a cam disc acting directly or indirectly, for example through intermediate levers, on a press plate, and a tobacco slide are operated by an operating lever.

In apparatuses of this type it is already known to effect the movement of the press plate for compressing the tobacco by swinging an operating lever through a first part of an angle and to eject the compressed tobacco by means of the slide into the paper cigarette tube by movement of the lever over the remainder of said angle. In such arrangements it is found thatonly definite predeterminedlengths of paper cigarette tubes can be filled, while tubes of ditferent lengths are not utilisable because of the predetermined path of the slide for the operation of ejecting the tobacco.

The primary object of the invention is to adapt the filling operation to variou lengths of cigarette tubes. This object is achieved by providing the cam disc with a stop which is joined fast but adjustably to the camdisc and which limits the movements of the tobacco slide by cooperation with stationary stop surfaces projecting into its path of movement. For this purpose the stop may be mounted. rotatably on the driving shaft of thecam disc and be adjustable and fastenable with the aid of jecting through a slot-shaped aperture in the projection.

It preferably cooperates with the stop surfaces through a finger formed on it and penetrating into a stationary aperture which is providedin the casing of the apparatus and the bounding surfaces of whichform the stop surfaces. Depending on the positions of the stop, the latter cooperates earlier or later with the stop surfaces. When the swinging angle of the cam disc and of the operating lever is varied the length of the column of tobacco ejected is adapted to the length of the paper cigarette tube.

In devices provided wit-h clamp means for securing and releasing the paper cigarette tubes, the stop can be utilised for controllingsaidclamp means.

It is a further object of the invention to facilitate the ejection of the tobacco and to permit complete filling of the cigarette paper tubes. curved portion of the cam disc which cooperates with the press plate can be provided with at least one recessed face portion, whereby the initially more powerful pressing operation is followed by premature relaxation of the press late. t p Preferred embodiments of the invention are illustrated by way of example in the accompanying drawing in which:

FIGURES 6 and 7 show further embodiments of the invention in sectional plan view,

FIGURES 8 and 9 illustrate various cam discs for use with the devices of FIGS. 1 to 7 in plan view, and FIGURE 10 shows a detail of the apparatus of FIG. 1 in elevation.

The apparatus shown in FIGS. 1-5 has a bottom casing part 1 and an upper casing part 2 adapted to fit on to the lower part. The casing supports the operating elements of the apparatus. The lower part 1 of the casing is provided with a slot-shaped aperture 3 through which passes an operating lever 5. The lever 5 is fixed on a shaft 4 which is journaled in the casing. The end of the lever 5 which passes out of the aperture carries a rotatable handle 6. A cam disc 7 is made fast: to the shaft 4 and the lever 5, and acts on a press plate 9 through a rockable intermediate lever 8. The press plate 9 is slidable in the bottom part 1 of the casing in the direction toward a tobacco magazine 11; against the action of springs it) and at the end penetrating into the magazine is bounded by a surface 9 curved in the shape of an arc of a circle and adapted to the peripheral surface of the paper cig arette tube. a

At its upper side the magazine It is provided with a filling aperture 12 which is aligned with an aperture 12' in the upper part 2 of the casing. The apertures 12 and 12' enable tobacco to beintroduced into the magazine II. A longitudinally slidable tongue 13 also projects into the magazine 11 and holds fast an ejecting slide 14 which is guided in a longitudinal slot 15 in the bottom part 1 of the casing. The slide 14- carries a driver pin 17 which projects into the aperture 3 and can be brought into operative connection with the operating lever 5. For this purpose the latter has a guide slot 16 in which the driver pin I7 engages when the operating leverS is swung accordingly. t

On the side situated opposite the slide 14 in the showing of 2, a tube 18 is connected to the magazine 11. The cigarette tubes can be pushed on to the tube 18 and secured by means of clamp tongs 19. The tongs are rockable by means of a slide 21 about a stationary pin 28 mounted on the bottom part 1. The slide 21 is ac commodated in a guide slot in the bottom part 1 of the casing and adapted to be moved longitudinally against the action of a spring 22 by a two-armed lever 23 which is rotatable at 2d.

The rotational movements of the lever 23 are actuated f the cam disc '7. The stop 26 is movably mounted on the For this purpose the trailing the cam disc 7, the press top end of the shaft 5 and connected to the cam disc 7 by a clamping screw 27 guided in a slot 28. The stop 26 15 associated with a recess 29 which is provided inthe bottom part 1 of the casing and extends over the swinging path of the cam disc 7. The walls 36, 31of the recess z 'form the abutment surfaces for the stop 26or an abutment finger 26' formed thereon and penetrating into the recess. An aperture 32 above the screw 27 in the upper part 2 of the casing permits the passage of a tool for loosening or tightening the screw 27. During the operation of the apparatus, the aperture 32 is closed by an insert 32, preferably of transparent material.

The operation of the apparatus will be described with initial reference to FIGURE 2. The operating lever 5, plate 9, and the slide 14- with its tongue 13 are in the starting position. The plane surface 25' of the stop 26 engages the lever 23, and the slide 21 is withdrawn by the spring 22 from the clamp tongs 19, so that the latter are opened by a non-illustrated spring and a paper cigarette tube can be placed on the tube 18 (see FIG. 10). After tobacco has been introduced through the

apertures

12 and 12 into the magazine 11, the operating lever S is swung clockwise to bring the curved portion 7' 'of the cam disc 7 into contact with the intermediate lever 8, whereby the intermediate lever /w pushes the press/pla 9 toward the magazine 11, and the tobacco contained therein is compressed into a ohann, FIG. 4. At the same time the cam 25 rocks the lever 23, and the slide 21 closes the clamp tongs 19 about the paper cigarette tube on the tube 18.

After this first angular movement of the operating lever into an intermediate position, it is further rocked to actuate ejection of the tobacco by the cooperation of the pin 17 and guide slot 16, P16. 3. The slide 14 with the tongue 13 is moved by the operating lever t ward the paper tube 18 and the column of tobacco contained in the magazine 11 is inserted through the tube 18 into the paper cigarette tube held on the latter. The operating lever 5 assumes the terminal position of maximum angular displacement from the starting position, as illustrated in FiGURE 3. In this position the slide 14 with the tongue 13 has been pushed out into the outer end position filling cigarette paper tubes of great length.

When the operating lever 5 is swung back, the slide 14 is first brought back until the pin 17 passes out of the guide slot 16 in the intermediate position of the lever 5, and thereupon, as the cam disc '7 and stop 2% are turned further back, with the assistance of the restoring force of the springs lit, the intermediate lever 8 and the press plate 9 are brought into their starting positions. At the same time, the return movement of the lever 2 25 enables the slide 21 to be brought back so that the clamp tongs 19 are opened and release the filled paper cigarette tube. If it is desired to fill paper cigarette tubes of shorter length, the screw 27 is loosened, and the stop 26 is swung toward the wall 31 (FIGURE 4) while the position of the cam disc 7 remains unchanged. After tightening of the screw 27, the stop 26 is again locked on the cam disc.

After a quantity of tobacco has been introduced into the magazine 11 and a paper cigarette tube placed on the tube 18, the operating lever 5 is turned in the previously described manner, the press plate 9 is moved in order to compress the tobacco, and through the subsequent cooperation of the operating lever 5 and pin 17 the slide 14 with the tongue 13 is moved in the direction of the tube 18 in order to eject the tobacco. This ejection operation is stopped when the finger 26' of the stop 26 bears against the wall 31 of the recess 29 (FIGURE 4). It is found that in dependence on the positions of the stop 26 and the cam disc 7 the swinging movements of the operating lever 5 are terminated earlier or later and thereby the slide 14 with its tongue 13 is moved farther or less far in the direction of the paper cigarette tube. The tobacco is not excessively compressed when it is pressed into paper cigarette tubes of shorter length, nor is it left loose in paper cigarette tubes of great length.

The cam disc illustrated in FIGURES 2 to 5 may be replaced by cam discs which are stepped in the manner illustrated in FIGURES 8 and 9. In the cam 57 1llustrated as an example in FIGURE 8 the operative curved portion 57' is provided with a shoulder 33 extending over trailing portion (in the direction of pressing), whereby towards the end of the ejection movement the pressure is released in order to facilitate the ejection and complete filling of the paper cigarette tubes with tobacco. If on the other hand a cam disc 47 of the type illustrated in FIGURE 9 is used, after full pressure is exerted at the beginning by a curved cam portion 47', there is a temporary relaxing of pressure over the region of the shoulder 33, While the major portion of the tobacco column is ejected into the paper cigarette tube, and towards the end of the ejection movement the pressure for the remainder of the tobacco is increased again over the region of the curved portion 47", in order to fill a tube of greater length uniformly.

The movable parts of the apparatus, such as the cam disc 7, stop 26, intermediate lever 8, press plate 9, lever 23, slide 21, and clamp tongs 19 or slide 14 are made of synthetic plastic in the embodiments illustrated.

FIGURE 6 shows an apparatus in which the cam disc 7 acts directly on a press plate 34 in a known manner. The cam disc 7 is provided with a curved portion 7' of the type illustrated in FIGURES 1 to 5, but may also have a curved portion of the type illustrated in FIG-

URES

8 and 9. It carries a fixed but adjustable stop 26 which abuts against the

stationary walls

30, 31 to terminate the rocking movements of the operating lever 5 earlier or later and to permit the uniform filling of paper cigarette tubes of different lengths.

The further embodiment illustrated in FIGURE 7 shows a stop 126 for a cam disc. the sliding movements of the press plate 37 mounted in a guide 36 on the bottom part 35 are actuated by means of a link or parallelogram linkage 38 which is operated through a pin 38' and a cam slot 39 on the disc 4d. The driving shaft 41 of the disc 46 is connected to an operating lever (not illustrated) and through links 42, 43 acts on a tobacco slide 44 having a tongue 45 which passes through the paper receiving tube 46 during the ejection operation. The stop 126 is loosely mounted on the driving shaft 41 and i adjustably fastened to the disc 46 by means of a clamping screw 27 and shift'able in a slot 28. A finger 26' on the stop 126 engages a recess 29 whose

walls

30, 31 stop the finger 26. Depending on the position of the stop 126, the finger 26' abuts against the

walls

30, 31 after movement of the operating lever through a smaller or larger angle for filling shorter or longer paper cigarette tubes.
