Description

The invention relates to a feeder of filter pieces in a machine of the tobacco processing industry, in particular filter attachment machine, with at least two magazines for filter rods, the filter rods are cut after removal from the magazines in filter pieces on a cross-axially conveying conveyor drum, and a machine of the tobacco processing industry, in particular filter attachment machine. Furthermore, the invention relates to a method for feeding filter pieces from at least two magazines in a machine of the tobacco processing industry, in particular Filteransetzmaschinewobei the filter pieces are removed from the magazines and cut into filter pieces on a cross-axially conveying conveyor drum.

In the document GB-A-2 267 021 is a Filteransetzmaschine described in which two magazines each filter rods are removed. After removing a first filter rod, this filter rod is cut centrally and pushed apart laterally. Subsequently, a second filter rod from the other magazine centered inserted between the sections of the first filter rod. This filter rod assembly is subsequently cut, staggered and pushed on drums respectively. This process - cutting, staggering and moving the filter pieces - is repeated and thus executed a total of twice. The resulting combination filter of the two different filter rods is subsequently transferred to a compilation drum with cigarette rods.

In US-A-4 044 659 a device for producing combined filter plug for filter cigarettes is described, being removed from two storage containers filter rods and cut. Through respective groups of cross conveyors cut from the filter rods filter plug are conveyed to a transfer conveyor.

The filter rods are removed from two separate magazines and subsequently cut in each case on a cutting drum several times to filter plugs and then each passed to a staggering drum. Thereafter, the staggered filter plugs are conveyed via further drums to a common compilation drum on which both types of filter plugs are pushed together and fed to a discharge conveyor which transports the filter plug groups to a transfer conveyor. By means of the transfer conveyor, the filter plug groups are transferred to a subsequent filter rod machine.

Furthermore, in US-A-2 649 761 a Filteransetzmaschine shown. Filter rods are removed from a filter magazine and cut several times into filter plugs. The cut filter plugs are delivered to a conveyor belt, at the end of which the filter plugs are arranged centrally on a conveyor drum by means of a removal drum. On both sides of the filter plug tobacco sticks are arranged on both sides of the filter plug from separate and parallel juxtaposed magazines, so that subsequently the tobacco rod filter plug tobacco rod groups are provided with a tipping paper respectively.

In GB-A-1 264 483 a device for the production of filter pieces for cigarettes is described, being taken from two magazines by means of a respective removal drum multiple-length filter rods and then cut on the removal drum by means of cutting blades in filter plugs. Thereafter, the cut filter plugs are each transferred to a conveyor belt, so that the filter plug are conveyed longitudinal axial. When transferring the cut filter plug to the respective conveyor belt filter plugs are additionally spaced in the longitudinal axial direction. For this purpose, the conveyor belts are further arranged with an inclination to the longitudinal axis of the filter plug. Subsequently, the longitudinal axial funded filter plugs are assembled in a zippered method on a common conveyor belt.

Moreover, in DE-A-198 56 934 describes a device for producing filter cigarettes with multiple filters, wherein filter components are inserted between two longitudinally axially spaced tobacco rods in a first step. Subsequently, further filter plugs are inserted at a subsequent assembly drum between the tobacco rod pairs longitudinally offended together with the first inserted filter plug. The filter components are placed here on two different conveyor paths separately between the longitudinally spaced tobacco rods.

In the patent U.S. 5,984,851 A filter feed in a filter attachment machine will also be described. For this purpose, the filters or filter pieces are cut several times in succession on the drums, staggered and moved. By means of the disclosed feeder, the cigarette groups can be delivered with single or dual filters.

Based on this prior art, it is an object of the present invention to provide a simple and variable supply of filter rods from at least two magazines, the filter rods from the respective magazine as long as possible can be performed separately on their respective conveying path to the groups of cigarettes.

The first solution of the problem is proposed in a feeder of the type mentioned that the magazines are arranged such that the conveying planes of the filter rods are offset in parallel. The term "conveying plane" is understood in particular to mean a plane in which filter rods are removed from a magazine and in which the filter rods are transported in the conveying direction. In a geometric view, the filter rods are each perpendicular to the

Conveyor plane arranged. In the conveying plane itself several drums can be arranged so that the filter rods can be transferred from one drum to another.

The invention is based on the idea to exploit the structural depth of a machine by a spatial displacement of the magazines for the filter rods, so that at the same time filter rods are removed from the magazines, wherein the sampling points are spatially displaced, i. do not lie in a conveyor plane. According to the invention, the conveying planes of the filter rods are then offset parallel to each other.

There are preferably provided a plurality of conveying sections of the filter pieces.

In a first conveying section are advantageously provided, based on the conveying direction of the filter rods, at least one removal drum for the filter rods from the magazines and at least a first staggering drum.

Preferably, at least one first sliding drum is provided in a second conveying section.

Furthermore, at least one staggering drum and / or at least one second sliding drum are provided in particular in the second conveying section.

Advantageously, at least one accelerator drum or staggering drum are provided in a third conveyor section.

The invention is based on the further idea that filter rods from the magazines and the filter pieces each side by side to the last or penultimate drum of the filter feed parallel and side by side, i. along axial axial offset, guided. To make this possible, in the arrangement of the drums, the width of the feeder or the filter attachment machine is important. In the context of the invention it is provided that the drums of the second conveyor section, the filter pieces in parallel and next to each other simultaneously transport. This means that the filter pieces are pushed at least on a first sliding drum simultaneously and side by side.

In further possible subsequent and variable process sequences of the second conveying section, the filter pieces can be staggered on the common drum simultaneously and next to one another and pushed onto the likewise common sliding drum or assembled into a filter. The drums of the first conveyor section may be formed together for the filter rods from the various magazines. In addition, depending on the spatial arrangement of the magazines, the respective drums can be designed individually for each conveying path of the filter pieces. In the latter case, it is necessary that the removal drums and possibly also the staggering drums for each magazine are arranged spatially offset from one another.

By means of the feed device according to the invention a high variability is achieved, since both combination filter and a higher production capacity can be achieved. Taking advantage of the structural space of a machine, the filter rods from different magazines and the filter pieces in each different Transported levels or on different routes. In this case, the number of rotatable axes is kept as low as possible according to the invention, so that the machine drive can be designed easier.

According to an advantageous embodiment of the invention it is proposed that at least a second staggering drum is arranged in the first conveyor section. After a first staggering in the first conveyor section takes place at least a second staggering of the filter pieces. As a result, the distance in the conveying direction between two filter pieces is increased.

Furthermore, advantageously, the drums of the first conveyor section have substantially the same width.

Reliable guidance of the filter pieces in the second conveyor section is ensured when the drums of the second conveyor section have substantially the same width.

Preferably, the drums of the first conveyor section and the drums of the second conveyor section have the same width. In this case, the filter pieces of all drums can be guided simultaneously, parallel and side by side offset in the filter attachment machine. For this purpose, the drums are equipped with extended axes.

In an advantageous development, the removal drums for the first magazine and the removal drum for the second magazine are arranged offset from each other in parallel.

In addition, according to an alternative embodiment, a common removal drum is provided for the first magazine and for the second magazine.

Furthermore, according to an advantageous development of the invention, the staggering drums of the first conveying section are arranged offset from each other in parallel.

Furthermore, at least one cutting device is provided in the first conveying section, preferably on at least one removal drum.

In order to produce combination filters, at least one cutting device is preferably provided in the second conveying section, preferably on the first sliding drum.

In addition, the object is achieved by a machine of the tobacco processing industry, in particular filter attachment machine, which is equipped with a feed device according to the invention described above.

In the method of the type mentioned, the solution of the problem is that the filter rods are guided in mutually parallel offset conveying planes.

In the conveying direction, the filter rods are each advantageously removed from the magazines by means of a removal drum and staggered by means of at least one first staggering drum in a first conveying section.

The filter rods are preferably displaced in a second conveyor section on a first sliding drum.

In a further development of the invention, the filter pieces are staggered in the second conveyor section by means of a staggering drum and / or at least partially displaced by means of a second sliding drum.

Further ip is proposed a further development that the filter pieces are delivered in a third conveyor section by means of an accelerator drum or stagger drum groups of cigarettes.

In order to achieve an even greater variability in the filter feed on a machine, in the first conveying section the filter pieces are staggered by means of at least one second staggering drum at least once more.

In addition, the filter rods in the first conveyor section, preferably on the removal drum, preferably cut, so that a smaller number of filter pieces are produced from a removed filter rod.

Combination filters can be easily produced, in particular, if at least part of the filter pieces, in particular on the staggering drum, are cut in the second conveying section.

Before the filter rods or filter pieces are continued to the accelerator drum and thus to the groups of cigarettes, according to the invention, the filter pieces are assembled in the second conveyor section to filter groups, so that the various filter pieces of several, in particular two, magazines result in a combination filter.

an embodiment of a feeding device for a double-lane filter attachment machine.

In the following description of the figures, the same or similar elements are denoted by the same reference numerals, so that a new idea is omitted.

In Fig. 1, the front view of a filter attachment machine of the MAX type is shown by the applicant. This machine has the following details: An infeed drum 111 transfers the cigarettes produced on a cigarette making machine to two relay drums 222 which deliver the staggered cigarettes in stacks and in rows of two each with a space between the cigarettes to a gathering drum 333.

The filter rods pass from a magazine 40 onto a removal drum 60 where they are cut into filter stoppers of double use length, staggered on a staggering drum 70, aligned by a sliding drum 80 to a series of consecutive plugs and an accelerator drum 90 in the interstices of cigarette rows on the compilation drum 333th stored. The cigarette filter cigarette groups are pushed together and taken over by a transfer drum 110.

A tipping paper strip 120 drawn from a tipping paper bobbin 130 is glued by a gluing device 140 and then cut in a cutting device 160 on a cutting drum 170 by the blades of a cutterhead 180 in tufts. The separated pad sheets are adhered to the cigarette filter-cigarette groups on the transfer drum 110 and rolled on a roller drum 190 around the cigarette filter groups.

The finished double-filter cigarettes are fed via a drying drum 210 to a cutting drum 220 and assembled thereon into single-filament cigarettes by means of central cutting through the filter plugs. A turning device 230 turns the series of filter cigarettes and at the same time transfers them into the continuous unswept series of filter cigarettes. The filter cigarettes pass through a test drum 240 to an ejector drum 260. A take-off drum 280 cooperating with a brake drum 270 places the filter cigarettes on a take-off belt 290.

Fig. 2 shows an enlarged view of a feeder 50 according to the prior art. The filter rods from a magazine M are removed by means of the removal drum 11 and cut by means of the cutting device 12, which consists of a knife 12.1 and a grinding wheel 12.2 for regrinding the knife 12.1. Subsequently, the cut filter pieces are staggered on the staggering drum 13, passed to a sliding drum 21, on which the filter pieces are arranged in a row one behind the other. The filter pieces are subsequently transferred to an accelerator drum 31 and delivered to the groups of cigarettes.

Fig. 3 shows a first embodiment of a feeder according to the invention. By means of a removal drum 11 filter rods from two magazines M1, M2 are removed simultaneously. The magazines M1 and M2 are offset from each other in the direction perpendicular to the plane of the drawing (see Fig. 4).

Fig. 4 shows the spatial arrangement of the magazines M1 and M2 in a schematic plan view. The magazines M1 and M2 with their conveying planes F1, F2 are parallel offset from each other. The filter rods in the magazines are removed from the magazines M1, M2 at two locations arranged one behind the other in the circumferential direction by the removal roller 11. The removal of the filter rods from the magazines M1 and M2 takes place in the parallel offset conveying planes F1, F2 simultaneously. The filter rods are each arranged longitudinally and at a predetermined distance from one another. In the context of the invention, the magazines M1 M2 can also be formed one behind the other, so that the filter rods can be removed from the magazines M1 M2 at the same point in the circumferential direction of the removal drum.

After removal, the filter rods are cut at the cutting devices 12, respectively. The cut filter pieces are staggered on a staggering drum 13 and subsequently on a further, second staggering drum 15. The removal drum 11 and the staggering drums 13, 15 form the first conveying section I of the filter pieces. The twofold staggered filter pieces are pushed together in the following conveyor section II to each of a series of filter pieces lying one behind the other. In other words, two separate rows of filter pieces are formed on a common sliding drum 21. To produce combination filters, a number of the filter pieces are cut by a cutter 22. The cutting device 22 consists of a knife 22.1, which is kept continuously sharp with a grinding wheel 22.2. The two rows of filter pieces formed on the sliding drum 21 are staggered by means of the staggering drum 23 and passed on to the second sliding drum 25. On the sliding drum 25, the filter pieces are moved again, so that the staggered shifted filter pieces by means of the accelerator drum 31, which is designed as a staggering drum, are assembled to a filter of double length.

In an alternative embodiment, the production capacity can be increased by eliminating the cutting device 22, if from the magazines M1 and M2 filter rods of the same kind are removed.

The acceleration and staggering of the filter pieces taken over by the sliding drum 25 forms the third conveying section III of the filter pieces. While in the conveying sections I and II, the drums each have two rows of filter pieces, only a number of filter pieces or filters is present on the accelerator drum 31.

FIG. 5 shows a further alternative embodiment according to the invention in a side view. Here, the filter rods are transported from the magazine M1 in the first conveyor section I separated from the filter rods from the magazine M2 to the common drums of the conveyor sections II and III. The conveying section I of the filter rods from the magazine M1 takes place via the removal drum 11.1 and the two staggering drums 13.1 and 15.1. The spatially, transaxially offset to these drums conveyor drums - removal drum 11.2, staggering drum 13.2, staggering drum 15.2 - promote the filter rods from the magazine M2 to the common sliding drum 21 of the second conveyor section II on a parallel offset conveying path.

Analogous to the first embodiment shown in FIG. 3, the filter rods from the magazines M1 and M2 are also separated in this second example and transported parallel to each other in the respective conveyor section I. The following drums of the conveyor sections II and III correspond to the drums of the first embodiment (FIG. 3).

In the figures 6 and 7 are respectively schematic arrangements of filter rods or pieces according to their position in the respective drums of Fig. 3 and Fig. 5 is shown. For clarity, the filter rods from the two magazines M1, M2 are shown differently graphed. The non-hatched filter rods 100 are removed from the magazine M1 and the hatched filter rods 200 from the magazine M2. The filter rods 100, 200 are each arranged perpendicular to their conveying plane F1, F2.

After removal of the filter rods 100, 200 by means of the common removal drum 11, these filter rods 100, 200 cut by means of cutting devices 12 in the same length filter pieces. Subsequently, the filter pieces from two magazines M1, M2 staggered. Depending on the requirement, it is necessary to stagger the filter pieces only once or several times, so that the cut filter pieces 100, 200 can be arranged on the first sliding drum of the conveying section II in a row. The parallel rows of filter pieces 100, 200 on the sliding drum 21 are staggered by the staggering drum 23 offset transversely, so that on a subsequent second sliding drum 25 of the conveying section II, the filter pieces 100, 200 from the two magazines M1, M2 can be arranged in a row , Subsequently, by means of the common accelerator drum or staggering drum 31 in the third conveyor section III staggering and delivery to the cigarette groups.

In the embodiment of FIG. 6, the production capacity can be increased at the Filteransetzmaschine because twice by means of the double-width drums of the conveyor sections I and II twice as many filter pieces are delivered to the cigarette groups.

By means of the removal drum 11 filter pieces 100, 200 are removed from the magazines M1 and M2. The filter rods 100, 200 which are six times long in the present case are cut by means of a cutting device 12 into six filter pieces of the same length. In the context of the invention, it is possible that, depending on the cutting devices multiple filter pieces, preferably 4- to 12-fold cut. On the subsequent first staggering drum 13, the cut filter pieces are each staggered, wherein two filter pieces per conveying plane in a trough of the staggering drum 13 are arranged at a predetermined distance from each other. By means of the second staggering drum 15, the filter pieces are staggered once again, so that only one filter piece per conveying plane is arranged in each trough of the staggering drum. The operations described above are performed in parallel both for the filter pieces 100 in the conveying plane F1 and for the filter pieces 200 in the conveying plane F2. In the subsequent conveying section II, the filter pieces are first arranged on a common sliding drum 21 in a row, staggered by means of a staggering drum 23. On the following sliding drum 25, the filter pieces are formed in the various conveying planes F1, F2 to a series of filter pieces lying one behind the other. In the subsequent conveying section III, the filter pieces are accelerated or staggered from the various conveying planes F2.

According to the embodiment in Fig. 7, the filter rods 100, 200 from the two magazines M1, M2 conveyed in the conveying section I parallel to each other. The promotion of the filter rods or pieces 100, 200 takes place by means of spatially separated, transversely offset and offset parallel drums (see Fig .. 5). The filter rods 100, 200 are removed by means of the removal drums 11.1, 11.2 respectively the magazines M1 and M2 and cut. Depending on the application and the filter rod length, the filter rods 100, 200 are then staggered several times in their conveying planes F1, F2 by means of the staggering drums 13.1, 13.2, 15.1, 15.2 in the conveying section I. Subsequently, on the common sliding drum 21 of the conveying section II, the filter pieces 100, 200 are arranged from the two magazines in each case to a row one behind the other. To produce combination filters, the filter pieces 200 of a row are cut centrally with a cutter 22. Subsequently, a staggering takes place on the staggering drum 23 and a displacement of the filter pieces on the sliding drum 25. The combination of the double-length and symmetrical combination filter takes place on the staggering or accelerating drum 31 of the conveying section III.

In order to enable the parallel juxtaposition of the filter rods 100, 200 in the conveying planes F1, F2 from at least two magazines M1, M2 to the last or penultimate drum of the filter feed, it is provided according to the invention to perform the filter feed on broadened drums by exploiting the depth of space of a filter attachment machine , Here, the filter rods are guided in different conveying levels.

FIG. 8 schematically shows a further example of a feed device for a double-web filter tying machine. From the staggered parallel magazines M1, M2 are removed by means of the removal drums 11.1, 11.2 the filter rods 100 and 200 from the magazines M1 M2 and with the help of the removal drums 11.1, 11.2 arranged cutting devices 12 cut several times, so that when passing the Cut pieces of filter from the removal drums 11.1, 11.2 to the staggering drums 13.1, 13.2 filter pieces or filter plug double use length are provided, which are inserted into the interstices of cigarette rows or tobacco sticks on a compilation drum 41.

After a first staggering of the filter pieces of double use length on the first staggering drums 13.1 and 13.2, the filter pieces are staggered a second time on the staggering drums 15.1 and 15.2 in the first conveyor section I. In the subsequent second conveying section II, the filter pieces are arranged in the conveying planes F1 and F2 in a row on the sliding drum 21. Thereafter, the parallel rows of filter pieces are transferred to an accelerator drum 31 of the third conveyor section III and staggered on this accelerator drum 31 and staggering drum, so that the filter pieces are arranged parallel and offset from each other in the conveying planes F1 and F2.

After staggering the filter pieces in the third conveyor section III, the filter pieces are delivered to the double-width feed drum 41 of the double-lane Filteransetzmaschine and inserted into the spaces between two transversely axially arranged tobacco sticks 400, so that cigarette filter piece cigarette groups be formed. In a double-lane filter attachment machine, two double-length filter pieces are placed in parallel or offset parallel between two tobacco rods each.

In an alternative not shown here, a double-lane filter attachment machine is apart from the installation of the accelerator drum or staggering drum 31 in the third conveyor section, so that the arranged in parallel rows adjacent filter pieces of the sliding drum 21 in the second conveyor section directly to a feed drum. On this assembly drum a total of four tobacco sticks are arranged in two parallel rows in the transverse axial direction of the drum.

For a double-lane filter attachment machine, the sliding drum 21 of the second conveyor section II and / or the accelerator drum 31 of the third conveyor section III have twice the width. In another embodiment, not shown here, the drums of the first conveyor section III are also formed with twice the width.

In a double-lane Filteransetzmaschine the filter rods are each conveyed in parallel and side by side in two parallel conveying planes up to the double-width feed drum, so that the production capacity of a double-lane Filteransetzmaschine is increased by means of the feed device according to the invention. In addition, the number of rotatable axes of the transport drums is kept low, so that the drive of the machine is simple in construction.
