The invention relates to a device for stuffing prefabricated cigarette tubes, having a housing, a tobacco chamber, a tobacco rest associated with the latter, a movable press bar for shaping the tobacco placed into the tobacco chamber into a line, a counter bearing associated with the tobacco rest for one end of the tobacco line and a slide, which can be displaced relative to the housing in order to fill the tobacco line in the cigarette tube. On the slide a stop (29) is provided, which can optionally be activated or can optionally be attached to the slide, and which shortens the displacement path relative to the housing by a length when in the activated or attached state. The counter bearing is formed in such a manner that the counter bearing projects into the tobacco chamber by the length when the stop is activated or attached.

Description

Device for stuffing cigarette tubes

The invention relates to a device for stuffing prefabricated cigarette tubes, comprising a housing, a tobacco chamber, a tobacco support associated therewith, a movable pressing beam for forming tobacco inserted into the tobacco chamber into a strand, a tobacco support associated with the tobacco storage for one end of the tobacco rod, and a slider for filling the cigarette tubes with the tobacco rod relative to the housing displaceable slider.

Such a device is known from DE 41 10 830 C1. In order to be able to adapt the length of the tobacco chamber to different Füllraum lengths of cigarette tubes in this device, the abutment is designed as an adjustable longitudinal direction of the tobacco part, provided according to the number of cigarette tubes of different length to be stuffed at least two predetermined locking positions are.

Another, generic device is known from DE 20 2008 012 816 U1. In this, the tobacco support is displaceable relative to the abutment displaced by a distance in the direction of movement of the slider, which corresponds approximately to the length difference of the different Füllraum lengths. As a result, it is no longer necessary to make the abutment adjustable and lockable in certain positions. By displaceable in the direction of movement of the slider arrangement of the tobacco support this moves automatically into a position corresponding to the available length of the tobacco when acting in the displacement direction, a force exceeding the adhesion of the tobacco support in the housing. This is the case regularly when the end of the tobacco support facing away from the abutment comes into contact with the filter of a filter sleeve.

In order to be able to adapt in this embodiment, the length of the press beam to the Füllraum- length of the cigarette sleeve used in each case, the pressing beam on a fixed part and the pressing beam optionally complementary movable part.

Another, generic device discloses the US 2004/0200485 A1. In order to adapt the length of the tobacco chamber to different Füllraum- lengths of cigarette tubes an optional insertable at the abutment end end in the tobacco chamber insert is provided. This is so dimensioned that it not only adapts the length of the tobacco chamber to the filling space length of the cigarette tube in the state inserted into the tobacco chamber, but the insert also forms a stop for the wall of the slider carrying a sleeve for holding the cigarette tube, so that Also, the maximum displacement is adapted to the respective filling space length of the cigarette tube.

A disadvantage of these prior art devices that they make consuming and / or difficult to adapt to different Füllraum lengths of cigarette tubes.

The invention is therefore based on the object to provide an improved device for stuffing prefabricated cigarette tubes. In the apparatus according to the invention, a stop provided on the slide and optionally activatable or optionally attachable to the slide, in the activated or attached state, the displacement path relative to the housing by a certain length shortening stop is provided. By activating or attaching the stop, the displacement path is shortened approximately by a length by which the length of the filling space of a first cigarette tube differs from the longer filling space of another cigarette tube. In particular, the cigarette tube having the shorter filling space length may be a sleeve having a prolonged and / or filter portion supplemented by an activated carbon region so as to reduce the pollutant content inhaled when smoking a cigarette comprising a prefabricated filter sleeve.

The fact that the stop is provided on the slide or optionally attachable, it can be easily operated or assemble or disassemble, since the slider is in contrast, for example, the tobacco receiving chamber easily accessible and offers a relative to the tobacco receiving chamber considerably larger mounting space, so that the stop considerably larger and therefore easier to operate than a stop which can be introduced, for example, into the tobacco receiving chamber.

The abutment is then designed such that it protrudes with activated or attached stop by the same length in the tobacco chamber. In this way it is achieved that the length of the tobacco receiving chamber is adapted in a corresponding manner to the filling space length of the cigarette tube with the shorter filling space as the displacement path.

Preferably, a spout with a free, preferably beveled end is provided at an end portion of the slider, the outer diameter corresponds approximately to the inner diameter of a cigarette tube. To fill the sleeve, it is first pushed onto the spout, preferably by pressing down a cover provided on the slide, on which the pressing beam is provided, held stationary to the spout and finally by relocating back the slider is pulled over the tobacco pad, whereby the tobacco rod located thereon is displaced into the filling space of the cigarette paper tube.

The stop is formed in a particularly preferred embodiment of the device according to the invention as a separate component of an effective length, which is selectively attachable to a remote from the spout wall of the slider. This separate component can for example be attached to a sales unit for the device according to the invention and be mounted by the user latter in the simplest manner, he would like to fill with the device cigarette tubes with shorter Füllraum-length.

In particular, it is also possible with the device according to the invention to make it suitable in a particularly simple manner for filling three different cigarette tubes which differ in their filling space lengths, in that the sales unit has two optionally mountable stops which differ in their length. be attached. Accordingly, a suitability for filling four different cigarette tubes by adding three different stops, for five different cigarette tubes by four stops, etc. possible.

The abutment is - particularly preferably - formed by a provided in the tobacco receiving space insert whose length corresponds at least to the effective length of the longest stop provided. By "effective length" is meant the length by which the displacement path of the slider is shortened by activating or attaching the longest stopper.The shortening of the displacement path is then projected by the insert, whose cross section preferably corresponds to the cross section of a tobacco rod produced with the device , into the tobacco receiving chamber, when the slider is in its limited by the stop end position, in which when using the device, the tobacco receiving chamber is filled with tobacco.

In the drawings, an embodiment of an inventive device for stuffing prefabricated cigarette tubes is shown. Show it: Figure 1 is a perspective view of this embodiment obliquely from above with the lid closed and mounted stop, ie for filling cigarette tubes with shortened Füllraum lengths, with hidden lines are shown in phantom in part.

Fig. 5 shows the detail IV in Figure 4 in an enlarged detail view. FIG. 6 is the same view as in FIG. 5, but with the stop removed; FIG.

Fig. 7 is a view according to FIG. 1, however, with the lid completely open and the slide almost completely displaced back, and FIG. 8 is a partial perspective view with the cigarette tube indicated during the filling process of the latter.

The exemplary embodiment of a device according to the invention denoted by 100 in the drawing as a whole comprises a housing 1 with a base part 2, in which side recessed grips 3, 4 are incorporated.

The base part is made of plastic. In the base part 2 of the housing 1, a slider 8 is guided in a straight line in the direction of movement S between the inner side walls 5, 6 and the bottom wall 7 thereof. For fixing the slider 8 perpendicular to the bottom wall 7, the slider 8 comprises on both sides projections 9 which engage in complementary grooves 10 in the side walls 5, 6.

At the in Fig. 1, right, further designated with the front end of a spout 1 1 is provided on the slider 8, whose outer diameter is adapted to the inner diameter of a prefabricated cigarette tube Z, that this pushed onto the spout 1 1 without much game can be. To facilitate Aufschiebevorganges the free end of the nozzle 1 1 is laterally beveled.

The grommet 1 1 is integrally formed on a holding plate 12 at its end region lying opposite the laterally chamfered free end. To attach the spout 1 1 to the slide 13 grooves 14 are incorporated on the front wall, in which the holding plate 12 with its lateral edges from above can be inserted. At the rear end of the housing 1 shown on the left in FIGS. 1 and 2, a cover 15 is pivotably attached to the slider 8 about a horizontal axis X extending perpendicular to the direction of movement S.

The slider has an elongated recess 16 in the direction of movement S, which forms a tobacco chamber 17 and extends completely through the slider 8 in the vertical direction V.

The bottom of the tobacco chamber 17 forms a trough-shaped tobacco pad 18, the side almost abuts the side walls of the recess 16 and the lateral edges of longitudinal projections 19 of the tobacco chamber 17 are covered, so as to avoid tobacco between the lateral edges of the tobacco pad and the Walls of the recess 16 passes. The tobacco support 18 is made of a dimensionally stable material, such as metal and secured in the rear, protruding from the tobacco chamber 17 area on a arranged on the bottom wall 7 base on the base. There is sufficient play between the underside of the tobacco support 18 and the bottom wall 7 that the tobacco support 18 can pass unhindered through the grommet 10 when the slider 8 is displaced to the rear (as shown in particular in FIG. 7).

On the lower side 20 in the closed state of the cover 15, a press beam 21 is formed, the side 22 of which, when closed, points approximately hollow with the same radius as the tobacco support 18. The press beam 21 is further positioned so that it together with the side walls of the recess 16 under the tobacco pad 18 in the closed state upwards such that the tobacco chamber has an approximately circular shape in cross-section.

At the front end region in the closed state of the lid, a handle 23 which can be displaced towards the rear against an elastic force is attached to the lid 15. It has two extensions 24 which engage in against the elastic force to the rear displaced state of the handle in complementary recesses 25 of the slider 8. By the engagement of the extensions 24 in the recesses 25, the lid is locked against folding about the axis X.

For stuffing a prefabricated cigarette tube Z with tobacco, the tobacco chamber 17 is loosely filled with tobacco when the lid 15 is open. Subsequently, the open end of a prefabricated cigarette tube Z is pushed onto the spout 1 1 and the lid 15 closed by pivoting about the axis X. The cigarette tube Z is held in position on the spout 1 1 by a provided on the front portion of the lid 15 Anpressblock 26 presses the sleeve material over a portion of the circumference against the spout 1 1. In the closed position of the lid 15 of this is locked by actuation of the handle 23 and engagement of the extensions 24 in the recesses 25. Subsequently, the lid 15 is displaced together with the slide 8 to the rear, the cigarette tube Z pulled over the tobacco pad 18 and the tobacco by a held back end of the tobacco chamber 18 forming abutment 27 and thus the cigarette tube Z is pulled over the located in the tobacco chamber 17 tobacco rod. In order to be able to fill cigarette tubes Z with different filling space lengths with the device, the maximum displacement of the slide 8 relative to the base part 2 of the housing 1 can be changed. For this purpose, a stop 29 is provided which is optionally on a wall 28, the wall 13, which carries the spout 1 1, opposite, mountable (see in particular Fig. 5 and 6).

The stop 29 can be pushed from the open bottom of the slide 8 on the wall 28. For this purpose, the stop is formed in cross-section approximately like a "Ω" flattened in the vertical direction, between which foot 31 and its head 32 there are mutually facing slots 33 whose width is slightly smaller than the thickness of the wall 28. In the wall 28 a recess 34 is made in the middle, which is slightly wider than the width of the bridge 35 which connects the foot 31 to the head 32. In its mounted position (Figure 5), the stop 29 becomes a press fit due to the engagement of the wall 28 held in the slots 33 on both sides of the recess 34.

In the assembled state, the projection 29 reduces the maximum displacement path of the slide 8 in the displacement direction S relative to the base part 2 by the effective length D, which corresponds to the distance between the top of the foot 31 and the head 33.

So that the length of the tobacco chamber 17 can be shortened to the appropriate extent, the abutment 27 has a length L which corresponds to the effective length D of the stop 29 (see FIGS. 6 and 7). For this purpose, the abutment 27 is formed by an insert 36, for example made of plastic, whose cross section corresponds approximately to the cross section of the tobacco rod to be introduced into the sleeve. The insert 36 is positioned relative to the rear wall 37 of the base member 2 such that the spout 1 1 facing abutment surface 38 is aligned with the front-side rear wall 39 in the recess 16 when the stop 29 is not mounted and the slider is in its forward extreme position ,

If the stop 29 is mounted, the abutment surface 38 protrudes accordingly into the recess 16 by the effective length D of the abutment and correspondingly shortens the tobacco chamber 17.
