Description

The invention relates to a feed device for filter rods in a tobacco processing machine Industry, especially filter attachment machine, with at least two magazines for filter rods and one Machine of the tobacco processing industry, in particular Filter attachment. The invention further relates to a Method for feeding filter rods from at least two magazines in one machine of tobacco processing Industry, especially filter attachment machine.

In document GB-A-2 267 021 there is a filter attachment machine described, in which two filter cartridges each be removed. After taking a first one This filter rod is cut in the middle of the filter rods and pushed apart axially. Then will a second filter rod from the other magazine in the middle inserted between the sections of the first filter rod. This filter rod arrangement is shown below Drums each cut, staggered and pushed. This process - cutting, staggering and moving the Filter pieces - is repeated and thus total executed twice. The resulting combination filter the two different filter rods become below handed over to a compilation drum with cigarette sticks.

No. 5,984,851 also discloses a Filter supply described in a filter attachment machine. For this, the filters or filter pieces are also cut several times in succession on the drums, staggered and shifted. By means of the disclosed Feeders can be single or Dual filters are delivered.

Based on this state of the art, it is a task of the present invention, a simple and variable Feeding filter rods from at least two magazines to create, the filter rods from each Magazine separated as long as possible on their respective Funding route to the cigarette groups can.

The first solution to the problem is with a feed device of the type mentioned in the introduction that the magazines are arranged in such a way that the conveyor levels the filter rods are offset in parallel. Under the The term "funding level" becomes one level in particular understood, taken from a magazine in the filter rods and in which the filter rods in the conveying direction be transported. From a geometric point of view are the filter rods perpendicular to each Conveying level arranged. At the funding level itself several drums can be arranged so that the filter rods passed from one drum to another can.

The invention is based on the idea of a spatial Moving the magazines for the filter rods to use the structural depth of a machine so that filter rods removed from the magazines at the same time be, the tapping points spatially shifted are, i.e. are not in one funding level. According to the invention are then the delivery levels of the filter rods arranged parallel to each other.

There are preferably several conveyor sections of the Filter rods provided.

In a first conveyor section, based on the conveying direction of the filter rods, at least a removal drum for the filter rods from the Magazines and at least a first relay drum intended.

Furthermore, in particular in the second conveyor section at least one relay drum and / or at least one second sliding drum provided.

Advantageously, in a third conveyor section at least one accelerator drum or relay drum intended.

The invention is based on the further idea that Filter rods from the magazines next to each other until to the last or penultimate drum of the filter feed parallel and side by side, i.e. offset axially, be performed. To make this possible, the Arrangement of the drums the width of the feed device or the filter attachment machine of importance. As part of the invention provides that the drums of the second conveyor section, the filter rods parallel and next to each other at the same time. The means that the filter rods at least on one first sliding drum simultaneously and side by side be pushed.

In other possible subsequent and variable Procedures of the second funding section can the filter rods on the common drum at the same time and are staggered side by side and on the same common sliding drum pushed or to one Filters can be put together. The drums of the first Conveyor section can be used for the filter rods different magazines. In addition, depending on the spatial arrangement of the Magazine the respective drums for each conveyor path of the Filter rods can be formed individually. In the latter case it is necessary that the removal drums and possibly the relay drums for each Magazine are spatially offset from each other.

By means of the feed device according to the invention achieved a high variability because both combination filters as well as higher production output can be achieved. Taking advantage of the structural The filter rods become the spatial conditions of a machine from different magazines in different ones Placed on different levels or transported. The number of rotatable according to the invention Axles kept as low as possible so that the machine drive can be constructed more simply.

According to an advantageous development of the invention it is proposed that in the first funding section at least one second relay drum is arranged. After a first graduation in the first funding section finds at least a second staggering of the filter rods instead of. As a result, the distance in the conveying direction enlarged between two filter rods.

Furthermore, the drums of the first advantageously have Conveying section essentially the same width.

Reliable guidance of the filter rods in the second Conveying section is guaranteed when the drums of the second conveyor section is essentially the same Have width.

The drums of the first conveyor section preferably have and the drums of the second conveyor section the same width. In this case, the Filter rods from all drums simultaneously, in parallel and offset next to each other in the filter attachment machine be performed. For this, the drums are extended with Equipped axles.

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

It is also according to an alternative design one for the first magazine and one for the second magazine common removal drum provided.

Furthermore, according to an advantageous development the invention of the season drums of the first Conveying section offset parallel to each other.

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

To make combination filters is preferred at least one cutting device in the second conveyor section, preferably on the first sliding drum, intended.

In addition, the task is solved by a machine of the tobacco processing industry, in particular filter attachment machine, those with a previously described Feed device according to the invention is equipped.

In the process of the type mentioned at the outset Solution of the problem is that the filter rods in each other conveyor levels offset in parallel.

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

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

In a further development of the invention, the filter rods in the second conveyor section using a relay drum staggered and / or by means of a second Sliding drum shifted at least partially.

It is also proposed in a further training that the filter rods in a third conveyor section an accelerator drum or a relay drum of cigarette groups be delivered.

For even greater variability in the filter feed can be reached on a machine in the first conveyor section the filter rods by means of at least one second relay drum at least one more time staggered.

In addition, the filter rods in the first conveyor section, preferably on the removal drum, preferably cut so that from a removed Filter rod creates several, smaller filter pieces become.

Combination filters can then be easily be produced when in the second conveyor section at least some of the filter rods, especially on the relay drum.

Then the Filter pieces from both magazines M1, M2 staggered. ever upon request, it is only necessary to use the filter pieces to stagger one or more times so that the cut Filter pieces 100, 200 on the first sliding drum of the conveyor section II arranged in a row can be. The parallel rows of filter pieces 100, 200 on the sliding drum 21 staggered transversely axially offset by means of the relay drum 23, so that on a subsequent second sliding drum 25 of the conveyor section II, the filter pieces 100, 200 from the two magazines M1, M2 into a row can be arranged. Then takes place using the common accelerator drum or relay drum 31 in the third funding section III a graduation and Delivery to the cigarette groups.

6, the production output be increased on the filter attachment machine because by means of the double-wide drums of the conveyor sections I and II correspondingly twice as much filter pieces be delivered to the cigarette groups.

Filter pieces 100, 200 taken from the magazines M1 and M2. The in In this case, 6-times long filter rods 100, 200 are of equal length by means of cutting device 12 Cut filter pieces. Within the scope of the invention it is possible that depending on the cutting devices several times Filter pieces, preferably 4 to 12 times, cut become. On the following first relay drum 13 are the cut filter pieces each staggered, with two filter pieces per conveyor level in a trough of the relay drum 13 in one predetermined distance from each other. By means of the second relay drum 15, the filter pieces unblocked one more time, so that in each Trough the relay drum only one filter piece per conveyor level is arranged. The ones described above Operations are performed for both the filter pieces 100 in the Conveying level F1 as well as for the filter pieces 200 in the Delivery level F2 executed in parallel. In the following Conveying section II, the filter pieces are first on a common sliding drum 21 in a row arranged, de-scaled by means of a relay drum 23. On the subsequent sliding drum 25, the Filter pieces in the various delivery levels F1, F2 a series of filter pieces in a row educated. In the subsequent funding section III the filter pieces from the various delivery levels F2 accelerated or staggered.

According to the embodiment in Fig. 7, the Filter rods 100, 200 from the two magazines M1, M2 in Funding section I promoted parallel to each other. The Promotion of the filter rods or pieces 100, 200 takes place by means of spatially separated, axially offset and drums offset parallel to one another (cf. FIG. 5). The filter rods 100, 200 are removed by means of the extraction drums 11.1, 11.2 magazines M1 and M2, respectively removed and cut. Depending on the application and the filter rod length become the filter rods 100, 200 then several times in their funding levels F1, F2 by means of the relay drums 13.1, 13.2, 15.1, 15.2 staggered in funding section I. Then be on the common sliding drum 21 of the conveyor section II the filter pieces 100, 200 from the two magazines each arranged in a row one behind the other. Around Manufacture combination filters, the filter pieces 200 of a row with a cutting device 22 in the middle cut. Then there is a graduation the relay drum 23 and a displacement of the filter pieces on the sliding drum 25. The compilation of the double long and symmetrical combination filter takes place on the relay or accelerator drum 31 of funding section III.
