Description

Apparatus for stuffing cigarette sleeves

technical field

The invention relates to a device for stuffing a prefabricated cigarette sleeve, comprising: a shell; a shredded tobacco chamber; a shredded tobacco support assigned to the shredded tobacco chamber; The tobacco is shaped into a tobacco rod; a bracket for one end of the tobacco rod associated with the tobacco holder; and a slide movable relative to the casing to stuff the cigarette sleeve with the tobacco rod.

Background technique

This device is known from DE 41 10 830 C1.

In order to be able to adapt the length of the tobacco chamber to the different lengths of the stuffing cavity of the cigarette sleeve in this device, the bracket is designed as a part which can be adjusted in the longitudinal direction of the tobacco holder, for this purpose according to the different lengths of the stuffing cavity to be stuffed. The number of cigarette sleeves provides at least two predetermined stop positions.

Another similar device is known from DE 20 2008 012 816 U1.

In this device, the tobacco holder is mounted so as to be movable relative to the carriage in the direction of movement of the carriage by a distance approximately corresponding to the difference in length of the different stuffed cavity lengths. It is therefore no longer necessary for the carriage to be designed to be displaceable and to be locked in a defined position. Due to the displaceable setting of the cigarette holder along the direction of movement of the slide, the cigarette holder automatically moves into a position corresponding to the length provided for the shredded tobacco under the following conditions: in the direction of displacement A force is applied which exceeds the force-locking of the cigarette holder in the housing. This is usually the case when the end of the cigarette holder facing away from the bracket is in contact with the filter tip of the filter sleeve.

In order to be able to adapt the length of the pressure beam to the length of the filling cavity of the respective cigarette sleeve used in the above-described embodiment, the pressure beam has a fixed part and a movable part which optionally complements the pressure beam.

US 2004/0200485 A1 discloses another device of the same kind.

In order to adapt the length of the tobacco chamber to different blanking cavity lengths of cigarette sleeves, an insert is provided which can optionally be inserted into the tobacco chamber at one end of the carrier. The insert is dimensioned such that not only does the length of the tobacco chamber adapt to the length of the stuffing cavity of the cigarette sleeve when it is inserted into the tobacco chamber, but the insert also constitutes a stop for The wall of the carriage carries a receptacle for holding the cigarette sleeve, so that the maximum travel distance is also adapted to the relevant stuffing cavity length of the cigarette sleeve.

A disadvantage of the known devices described above is that they are complex to manufacture and/or are difficult to adapt to different filling cavity lengths of cigarette sleeves.

Contents of the invention

It is therefore the object of the present invention to provide an improved device for stuffing cigarette sleeves.

In the device according to the invention a stop is provided which is arranged on the carriage and which can be selectively activated, or which can be selectively mounted on the carriage and which stops at the activated Or shorten the displacement stroke relative to the housing by a length in the installed state. By activating or installing this stop, the displacement stroke can be shortened roughly by a length by which the length of the filling cavity of the first cigarette sleeve differs from the longer filling cavity of the other cigarette sleeve. cavity. In particular, a cigarette sleeve having a shorter filled cavity length is a cigarette sleeve having a transition mouth portion which is elongated and/or supplemented by an activated carbon site, so that when smoking a cigarette comprising a prefabricated filter sleeve Reduce the amount of harmful substances inhaled.

Since the stop is provided on the slide or can be selectively mounted on the slide, the stop can be easily operated or installed or easily loaded and unloaded, because for example, as opposed to the tobacco receiving chamber, the slide is easily accessible and provides A significantly larger installation space compared to the shredded tobacco receiving chamber, so that the stop can be designed significantly larger than, for example, a stop that can be inserted into the shredded tobacco receiving chamber and is therefore easier to handle.

The bracket is then designed such that it protrudes into the tobacco chamber with the same length when the stop is activated or installed. It is then achieved that the length of the shredded tobacco receiving chamber is adapted accordingly to the length of the filling cavity of the cigarette sleeve which has a filling cavity which is shorter than the displacement path.

It is advantageous to provide a socket on the slide, which socket has a free, preferably chamfered end, the outer diameter of which is approximately equal to the inner diameter of a cigarette sleeve. In order to stuff the cigarette sleeve, it is first pushed onto the socket; preferably by pressing down a cover arranged on the sliding seat (the pressure beam is arranged on the cover), the position of the cigarette sleeve relative to the socket is fixedly maintained; Finally, by the return movement of the slide, the cigarette sleeve is guided through the tobacco holder, so that the tobacco rod on the tobacco holder is moved into the stuffing cavity of the cigarette paper sleeve.

In a particularly preferred embodiment of the device according to the invention, the stop is designed as a separate component having an effective length, which can be selectively fastened to a wall of the carriage facing away from the socket. This separate component can, for example, be added to the sales unit of the device according to the invention and then installed in the simplest manner by the user himself, if the user wishes to use the device to stuff cigarette sleeves with a shorter filling cavity length.

Especially utilize device according to the present invention to also be able to achieve following object, exactly can make this device be suitable for packing three kinds of different cigarette sleeves that its stuffing cavity length differs very simply, for this reason the sales unit is accompanied by two Optionally fitted stops of varying lengths. Accordingly, if three different stops are provided, it is suitable for stuffing four different cigarette sleeves, if four different stops are provided, it is suitable for stuffing five different cigarette sleeves, and so on.

The bracket is (particularly preferred) formed by an insert arranged in the tobacco receiving cavity, the length of which is at least equal to the effective length of the longest stop provided. By "effective length" is meant the length by which the displacement travel of the carriage is shortened by the activation or installation of the longest stop. In order to shorten this displacement stroke, the insert (its cross-section Preferably corresponding to a cross-section of a tobacco rod produced with the device) protrudes into the tobacco receiving chamber.

Detailed ways

An exemplary embodiment of the device according to the invention, generally indicated at 100 in the drawing, comprises a housing 1 having a base 2 in which lateral actuating recesses 3 , 4 are formed.

The base is made of plastic.

In the base 2 of the housing 1 , between its inner walls 5 , 6 and the bottom wall 7 , a slide 8 is guided linearly in the direction of movement S. As shown in FIG. In order to fix the slide 8 perpendicular to the bottom wall 7 , the slide 8 has projections 9 on both sides, which can engage in complementary recesses 10 in the side walls 5 , 6 .

At the end shown on the right in FIG. 1 and referred to below as the front end, a socket 11 is arranged on the slide 8, the outer diameter of which is adapted to the inner diameter of a prefabricated cigarette sleeve Z such that The cigarette sleeve can be pushed onto the socket 11 without much play. In order to facilitate the push-in process, the free end of the socket 11 is laterally chamfered.

The socket 11 is integrally formed on a retaining plate 12 at its end region opposite the laterally chamfered free end. In order to fix the socket 11 on the slide, a recess 14 is formed in the front wall 13 of the slide, into which the retaining plate 12 can be pushed with its side edge from above.

At the rear end of the housing 1 , shown on the left in FIGS. 1 and 2 , a cover 15 is articulated pivotably on the slide 8 about a horizontal axis X extending perpendicularly to the direction of travel S. As shown in FIG.

The carriage has a longitudinally extending recess 16 in the direction of travel S, which recess forms a tobacco chamber 17 and extends completely through the carriage 8 in the vertical direction V.

The bottom of the shredded tobacco chamber 17 forms a shredded tobacco holder 18 of groove-shaped structure, which is almost against the side wall of the recess 16 in the lateral direction and the side edge of the shredded tobacco holder is then protruded by the longitudinal protrusion of the shredded tobacco chamber 17. Covered by the raised portion 19 to prevent shredded tobacco from entering between the side edge of the shredded tobacco holder and the wall of the cavity 16 .

The tobacco carrier 18 is made of a dimensionally stable material, such as metal, and is fastened in the rear region protruding from the tobacco chamber 17 to a base on the base, which is arranged on the bottom wall 7 . There is sufficient clearance between the bottom side of the tobacco holder 18 and the bottom wall 7 so that the tobacco holder 18 can pass through the socket 10 without hindrance when the slide 8 moves backward (as shown in particular in FIG. 7 ).

On the lower side 20 of the lid 15 in the closed position, a pressure beam 21 is integrally formed, the downwardly facing side 22 of which in the closed position is hollowed approximately at the same radius as the tobacco holder 18 . The pressing beam 21 is also positioned in such a way that the pressing beam together with the side walls of the recess 16 below the tobacco holder 18 can be closed upwardly in the closed state in such a way that the tobacco chamber has an approximately circular shape in cross section. shape.

In the region of the front end in the closed state of the lid, a handle 23 is attached to the lid 15 which can be displaced backwards against a spring force. The handle has two extensions 24 which engage in complementary recesses 25 of the slide 8 when the handle is displaced backwards against the spring force. By the engagement of the two extensions 24 into the recesses 25 , the lid is locked against opening about the axis X.

To stuff a prefabricated cigarette sleeve Z with shredded tobacco, with the lid 15 open, the shredded tobacco chamber 17 is loosely filled with shredded tobacco. The open end of a prefabricated cigarette sleeve Z is then pushed onto the socket 11 and the lid 15 is closed by pivoting about the axis X. The cigarette sleeve Z is held in its position on the socket 11 in such a way that a pressing piece 26 arranged on the front region of the cover 15 presses the sleeve material onto the socket 11 on a part of the circumference . In the closed position of the cover 15 , it is locked by actuating the handle 23 and pressing the extension 24 into the recess 25 . The cover 15 is then moved back together with the slide 8, wherein the cigarette sleeve Z is pulled through the cigarette holder 18 and the tobacco is held by a bracket 27 forming the rear end of the tobacco chamber 18, so that the cigarette sleeve Z is pulled Pass the tobacco rod in the tobacco chamber 17 .

In order that the device can also be used to stuff cigarette sleeves Z having different stuffing cavity lengths, the maximum displacement travel of the slide 8 relative to the base 2 of the housing 1 can be varied. A stop 29 is provided for this purpose, which can optionally be attached to a wall 28 opposite the wall 13 supporting the socket 11 (see in particular FIGS. 5 and 6 ).

The stop 29 can be pushed onto the wall 28 from the open bottom side of the carriage 8 . Furthermore, the stop is configured in cross-section approximately like a vertically flattened "Ω". Between its foot 31 and its head 32 there are slots 33 facing away from each other, the width of which is slightly smaller than the thickness of the wall 28 . A recess 34 is machined in the center of the wall 28 , the width of which is slightly greater than the width of the bridge 35 connecting the foot 31 to the head 32 . In its mounted position ( FIG. 5 ), the stop 29 is held on both sides of the recess 34 by a clamping seat formed by the engagement of the wall 28 into the slot 33 .

In the installed state, the stop 29 reduces the maximum displacement stroke of the carriage 8 relative to the base 2 in the direction of movement S by an effective length D corresponding to the upper side of the foot 31 and the length of the head 33 The distance between the upper sides.

In order to be able to reduce the length of the tobacco chamber 17 to a desired size, the bracket 27 has a length L which corresponds to the effective length D of the stop 29 (see FIGS. 6 and 7 ). Furthermore, the bracket 27 is formed by an insert 36, for example made of plastic, the cross-section of which corresponds approximately to the cross-section of the tobacco rod to be stuffed into the cigarette sleeve. The insert 36 is positioned relative to the rear wall 37 of the base 2 in such a way that when the stop 29 has not been installed and the carriage is still in its front limit position, the bracket face 38 facing the socket 11 and the end side rear in the pocket 16 The walls 39 are aligned.

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