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 optionally into the tobacco chamber 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.

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 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 thus easier to operate than can be formed, for example, in the tobacco receiving chamber insertable stop.

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 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.

In the drawings, an embodiment of an inventive device for stuffing prefabricated cigarette tubes is shown. Show it:

6 the same view as in 5 , but with the stop removed;

7 a view according to 1 but with fully open lid and almost completely zurückverlagertem slide and

8th a partial perspective view with indicated cigarette tube during the filling process the latter.

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

The base part is made of plastic.

In the base part 2 of the housing 1 is between its inner sidewalls 5 . 6 and its bottom wall 7 a slider 8th guided in a straight line in the direction of movement S. For fixing the slider 8th perpendicular to the bottom wall 7 includes the slider 8th on both sides projections 9 that are in complementary grooves 10 in the side walls 5 . 6 intervention.

At the in 1 shown on the right, hereinafter referred to as the front end is on the slide 8th a spout 11 provided, whose outer diameter is adapted to the inner diameter of a prefabricated cigarette tube Z, that this without much play on the spout 11 can be deferred. To facilitate Aufschiebevorganges is the free end of the spout 11 beveled laterally.

The spout 11 is at its laterally beveled free end opposite end portion of a holding plate 12 formed. For fastening the spout 11 on the slider are on the front wall 13 groove 14 incorporated, in which the holding plate 12 with its lateral edges from above can be inserted.

At the rear, in 1 and 2 left end of the housing shown 1 is about a horizontal, perpendicular to the direction of movement S extending axis X a lid 15 pivotable on the slide 8th hinged.

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

The bottom of the tobacco chamber 17 forms a trough-shaped tobacco pad 18 , the side almost on the side walls of the recess 16 rests and the lateral edges of longitudinal projections 19 the tobacco chamber 17 be covered, so as to avoid tobacco between the lateral edges of the tobacco pad and the walls of the recess 16 arrives.

The tobacco pad 18 is made of a dimensionally stable material, such as metal and in the rear, from the tobacco chamber 17 outstanding area on one at the bottom wall 7 arranged base attached to the base. Between the bottom of the tobacco pad 18 and the bottom wall 7 There is enough clearance that the tobacco pad 18 when moving the slider 8th unhindered to the rear through the spout 10 can penetrate (as in particular 7 shows).

At the closed state of the lid 15 lower side 20 is a press beam 21 molded, its in the closed state facing down side 22 is hollow with the same radius as the tobacco pad 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 closes up in such a way that the tobacco chamber has an approximately circular shape in cross section.

At the front end region in the closed state of the cover, a handle which can be displaced towards the rear against an elastic force is provided 23 on the lid 15 appropriate. It has two extensions 24 on, in against the elastic force to the rear shifted state of the handle in complementary recesses 25 of the slider 8th Indent. Through 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 is with the lid open 15 the tobacco chamber 17 loosely filled with tobacco. Subsequently, on the grommet 11 the open end of a prefabricated cigarette tube Z is pushed and the lid 15 closed by pivoting about the axis X. The cigarette tube Z is in position on the spout 11 held by one at the front of the lid 15 provided pressure block 26 the sleeve material over part of the circumference against the spout 11 suppressed. In the closed position of the lid 15 this is done by operating the handle 23 and engaging the extensions 24 in the recesses 25 locked. Subsequently, the lid 15 together with the slider 8th shifted to the rear, the cigarette tube Z on the tobacco pad 18 pulled and the tobacco through a the rear end of the tobacco chamber 18 forming abutment 27 held and thus the cigarette tube Z on the in the tobacco chamber 17 pulled tobacco rod is pulled.

In order to fill cigarette tubes Z with different filling space lengths with the device, the maximum displacement path of the slider 8th relative to the base part 2 of the housing 1 to be changed. This is an attack 29 provided, which optionally on a wall 28 that the wall 13 which the spout 11 carries, is opposite, mountable (see in particular 5 and 6 ).

The stop 29 can from the open bottom of the slider 8th on the wall 28 be deferred. For this purpose, the stop in cross-section is approximately like a flattened in the vertical direction "Ω" formed. Between his foot 31 and his head 32 find each other pointing slots 33 whose width is slightly smaller than the thickness of the wall 28 is trained. In the wall 28 is a recess in the middle 34 incorporated slightly wider than the width of the bridge 35 which the foot 31 with the head 32 connects, is. In its mounted position ( 5 ) becomes the stop 29 by a clamping fit due to the engagement of the wall 28 in the slots 33 on both sides of the recess 34 held.

In the assembled state reduces the approach 29 the maximum displacement of the slider 8th in the displacement direction S relative to the base part 2 to the effective length D, which is the distance between the top of the foot 31 and the head 33 equivalent.

Thus the length of the tobacco chamber 17 can be shortened to the appropriate extent points the abutment 27 a length L on which the effective length D of the stop 29 corresponds (see 6 and 7 ). This is the abutment 27 through an insert 36 formed for example of plastic whose cross section corresponds approximately to the cross section of the tobacco rod to be introduced into the sleeve.

The use 36 is relative to the back wall 37 of the base part 2 positioned so that the spout 11 facing abutment surface 38 with the frontal back wall 39 in the recess 16 Aligns when the stop 29 is not mounted and the slider is in its front extreme position.

Is the stop 29 mounted, so the abutment surface protrudes 38 accordingly by the effective length D of the stop in the recess 16 in and accordingly shortens the tobacco chamber 17 ,
