Description

The invention relates to a device for stuffing prefabricated cigarette tubes, with a housing, a tobacco chamber, a tobacco associated therewith, a movable pressing bar for forming tobacco inserted into the tobacco chamber into a strand, a tobacco support associated abutment for one end of the tobacco rod, and a 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 known.

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 from the DE 20 2008 012 816 U1 known.

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 the length of the press beam to the filling space length of the respectively used cigarette sleeve in this embodiment, the pressing beam has a fixed part and a pressing member that optionally complements the movable part.

Another generic device discloses the US 2004/0200485 A1 ,

In order to adapt the length of the tobacco chamber to different filling space lengths of cigarette tubes, an insert which can be inserted into the tobacco chamber, optionally on the abutment-side end, 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.

From the WO 97/20476 A1 Another device for stuffing pre-made cigarette tubes is known. It comprises a housing and a slide displaceable relative to the housing for filling the cigarette tubes with the tobacco rod. The housing has a stop in association with the ejection slide of the shape that the ejection slide can be moved back far different to the filling of a tobacco press chamber with tobacco.

A disadvantage of these prior art devices that they produce consuming and / or difficult to adapt to different filling chamber 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 selectively attachable to the slider, provided in the attached state, the displacement path relative to the housing by a certain length shortening stop. By attaching the stop, the displacement path is shortened by about 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 on the slide is optionally attachable, it can be easily assemble or disassemble, because the slide is in contrast, for example, easily accessible to the tobacco receiving chamber and offers a relative to the tobacco receiving chamber considerably larger mounting space, so that the stop considerably larger and thus easier operable as an insertable example, in the tobacco receiving chamber stop can be formed.

The abutment is then designed such that it protrudes when 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 bevelled end is provided at an end portion of the slider, the outer diameter approximately the inner diameter of a cigarette tube corresponds. 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 pulled over by relocating the slider over the tobacco support, 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 travel of the slider is shortened by activating the longest stop. In order to shorten the displacement path, the insert, the cross-section of which preferably corresponds to the cross-section of a tobacco rod produced with the device, projects into the tobacco receiving chamber when the slider is in its end position limited by the stop, in which the tobacco receiving chamber with tobacco is in use is filled.

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 on both sides of projections 9, which engage in complementary grooves 10 in the side walls 5, 6.

At the in Fig. 1 shown on the right, hereinafter referred to as the front end, a spout 11 is provided on the slide 8, whose outer diameter is adapted to the inner diameter of a prefabricated cigarette tube Z, that it can be pushed onto the spout 11 without much game. To facilitate the Aufschiebevorganges the free end of the spout 11 is laterally bevelled.

The grommet 11 is integrally formed on its side inclined to the free end end portion of a retaining plate 12. To attach the spout 11 to the slide 13 grooves 14 are incorporated in the front wall, in which the holding plate 12 with its lateral edges from above can be inserted.

At the rear, in Fig. 1 and 2 On the left end of the housing 1, a cover 15 is hinged to the slide 8 about a horizontal, perpendicular to the direction of movement S axis X a lid.

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 support 18, which abuts the side almost of the side walls of the recess 16 and the lateral edges of longitudinal projections 19 of the tobacco chamber 17 covers so as to avoid tobacco getting between the lateral edges of the tobacco pad and the walls of the recess 16.

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. Between the underside of the tobacco support 18 and the bottom wall 7 there is sufficient clearance that the tobacco support 18 when moving the slider 8 can penetrate unhindered through the spout 10 back (as in particular Fig. 7 shows).

On the lower side 20 in the closed state of the lid 15, a pressing beam 21 is formed, the downwardly facing side 22 of which is in the closed state approximately hollow with the same radius as the tobacco support 18. The pressing beam 21 is further positioned so that it coincides with the side walls of the recess 16 under the tobacco support 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 11 and the lid 15 is closed by pivoting about the axis X. The cigarette tube Z is held in position on the spout 11 by a pressing block 26 provided on the front portion of the lid 15 pushing the sleeve material against the spout 11 over part of the circumference. In the closed position of the lid 15, this is by actuation of the handle 23 and engagement the extensions 24 locked in the recesses 25. Subsequently, the lid 15 is displaced together with the slider 8 to the rear, wherein the cigarette tube Z pulled over the tobacco pad 18 and the tobacco held by a rear end of the tobacco chamber 18 forming abutment 27 and thus the cigarette tube Z over the located in the tobacco chamber 17 Tobacco rod is pulled.

In order to be able to fill cigarette tubes Z with different filling chamber 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 11, opposite, mountable (see in particular FIGS. 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 in cross-section is approximately like a flattened in the vertical direction "Ω" formed. Between its foot 31 and its head 32 are located facing each other from slots 33 whose width is slightly smaller than the thickness of the wall 28 is formed. In the wall 28 a recess 34 is incorporated centrally, which is slightly wider than the width of the bridge 35, which connects the foot 31 with the head 32 is. In its mounted position ( Fig. 5 ), the stop 29 is held by a clamping fit due to the engagement of the wall 28 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 slider 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.

Thus, the length of the tobacco chamber 17 is shortened to the appropriate extent, the abutment 27 has a length L, which corresponds to the effective length D of the stopper 29 (see Fig. 6 and 7 ). For this purpose, the abutment 27 through 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 abutment surface 38 facing the grommet 11 is aligned with the front-side rear wall 39 in the recess 16 when the abutment 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.
