[0010]

SUMMARY OF THE INVENTION The object underlying the present invention is to provide a method and an apparatus for increasing the production of multiple filters and a system for producing multiple filters.

[0011]

The object of the present invention is to provide a method for manufacturing multiple filters for products in the tobacco processing industry, comprising the following method steps:-having a filter element in the center of the filter sleeve. Supplying the filter sleeve to a predetermined position and introducing the filter element into the filter sleeve from at least a first side at a predetermined position so that a filter segment is formed in at least a portion of the filter sleeve. It is solved by consisting of steps.

By providing a filter sleeve which already has a filter element in the center of the filter sleeve, and by introducing the filter material in a predetermined proportion into this filter sleeve, the filter material is introduced into the filter sleeve. This makes it possible to relatively short-circuit the movements which the supply member has to carry out in order to load into it, so that a considerable time advantage is obtained. In the method steps described above, a filter sleeve with a central filter member is used and / or produced.

[0013] Within the framework of the present invention, the multiple filter comprises:
In particular, it is also understood as a multi-segment filter. In this case, the multi-filter has in particular at least two segments and at least two filter materials. In this case, the multi-filter is generally followed by a soft element, for example of cellulose acetate, followed by, for example, an activated carbon filter.
The granules are then provided with at least two or three or many segments of an arrangement such as a soft element consisting of a further cellulose acetate. In such a triple filter, a coating material such as paper is wound around the filter. When a filter sleeve having a filter element in the center is used, multiple filters are generally produced with a working length of two or more.

According to the invention, the central filter element, which is also referred to as a filter plug hereinafter, is held or glued centrally, for example during the supply of this element by a force or abutment of a corresponding element, or It is held in the center by a suitable adhesive force. The filter sleeve is held in a desired position by, for example, suction.

The filter sleeve is rotated so that, starting from the first side, the second part of the filter sleeve is filled, whereby the filter material is introduced into this second part of the filter sleeve, and thus the further filter If segments are to be formed, gravity is used for the supply of granules on both sides during filling of the filter sleeve. Furthermore, a filling station for the filling from the side, i.e. a processing station, is provided along the conveyor-in which the filter sleeve is housed in the housing of this conveyor-so that a compact construction of the machine is possible. Becomes

In the context of the present invention, a filter sleeve means a coating material part or a tubular coating, in particular molded into a tube, the coating material being, for example, paper.

A further increase in the production speed of multiple filters is
This is achieved if the filter material is applied in progressively discrete volume fractions and / or at least partially simultaneously in multiple volume fractions. By multiple quantity proportions or by single quantity proportions, in the context of the present invention, is meant a set or a stack of at least two different or identical filter materials, in which case multiple filter materials or one filter material Are introduced into the filter sleeve in one process step. The multiple filter materials are one, two or multiple granular materials, such as soft materials such as filter plugs made of cellulose acetate or fleece or hard materials such as sintered members, hollow cylinders or capsules. It is. The introduction of the filter material into the filter sleeve is effected by a vertical motion component. It is particularly advantageous that this vertical motion component is essentially completely vertical. In this case, the filter sleeve is oriented vertically or vertically to be filled. The granular material and, in particular, gas-permeable, boundary pieces are introduced alternately.

A particularly simple embodiment of the method according to the invention is that the first part of the filter sleeve is first almost completely filled before the filter sleeve is rotated, and then the filter is rotated after the rotation has taken place. Provided by substantially completely filling the second portion of the sleeve. As a result of this method step, a filter sleeve completely filled with one or more filter materials is obtained,
These filter sleeves are ejected for further processing. In particular, the filter coating material has a hot-melt adhesive seam from within, which hot-melt adhesive seam is activated by the heat supply when the fully filled filter sleeve is transported, whereby the filter material Is fixed in the filter sleeve.

An n-fold multiplex filter is produced, where n is a natural even number greater than one.

To produce multiple filters, a filter sleeve or a number of filter sleeves are moved along a given transport path, along which a number of different method steps are performed. A corresponding transfer path is provided for this purpose. The filter sleeve is transported at least partially over this transport path in the transverse direction.

One multi-filter or multiple multi-filters is made in the manner described above. In this case, the multiplex filter thus produced can be, for example, 2x, 4x and / or
Or a multi-filter having a filter rod length of 6 times and correspondingly different filter materials is cut into two, four or six filters. The used filter sleeve with the filter element in the center can be made, for example, on a modified MULFI-machine of the applicant. According to the present invention, a pre-prepared filter sleeve with a central filter element is used for producing multiple filters for products in the tobacco processing industry. With this use according to the invention, it is possible to significantly increase the production speed of a filter production machine for producing multiple filters.

A suitable filter sleeve is used to produce a multiple filter of n times working length, where n is a natural even number greater than one.

According to the present invention, there is provided a filter sleeve for making a multiple filter for products in the tobacco processing industry, wherein the filter sleeve comprises a coating material part molded into a tube, wherein the filter element is a filter element. It is provided in the center. This configuration of the filter sleeve according to the invention enables an increase in the production speed of the multi-filter production machine.

The filter element is essentially stationary with respect to the filter sleeve. If the filter element can be glued to the filter sleeve, position immobility can be easily achieved. In this case, the filter element is, for example, 4
It may be a filter element of two lengths between mm and 6 mm. One half of this length is arranged in a corresponding cigarette per finished filter.

The object is furthermore provided by a filter sleeve supply member and at least one transfer member filled with the filter sleeve, by means of which the filter sleeve can be supplied to at least one processing station. In an apparatus for producing multiple filters for products in the tobacco processing industry, this is solved by providing the processing station with a rotating device for rotating the filter sleeve.

The arrangement according to the invention of the device makes it possible to maintain the movement of the supply of filter material in a relatively short circuit, whereby the supply time is significantly reduced.

By processing station is meant, in the context of the present invention, in particular a station where the filter material is metered, the cutting process takes place and the filter material is introduced into the filter sleeve and / or similar stations. I do. During the feeding of the granules or immediately after the granules have been fed into the filter sleeve, the filter sleeve itself is vibrated, so that the densest possible agglomeration of the granules is obtained. A vibrating member is provided for this purpose. Regarding this vibration member, German Patent Publication No. 178 36
See No. 4.

The filter sleeve is a part of the covering material which has been prepared in advance, molded into a tube and provided with a filter material in the middle of the respective part. A particularly simple and compact construction of the device is achieved in that the at least one transfer element is at least one continuously rotating conveyor for transferring the filter sleeve in the transverse direction. A specially compact design is possible because at least one processing station is provided on only one conveyor.

A very modular construction of the device, in particular if at least one working station is provided on one part of the conveyor, in particular on a number of conveyors, but not on the other part of the conveyor. The format is possible, so that the filter specificity can be considered relatively quickly. In this case, suitable modifications or new adjustments of the device constructed in such a modular manner are possible. At most one processing station is provided for each conveyor. This configuration according to the invention enables a very modular design of the device.

At least one filter material supply station, at least one filter material loading station, at least one discharge station and / or at least one heating station are provided as processing stations. By means of the filter material supply station, the filter material is moved into the area of the filter material loading station or is introduced into the filter sleeve only by, for example, gravity. The discharge station discharges the manufactured and finished, filled filters or partially filled filter sleeves. The heating station serves to activate the hot melt bond, for example, to secure the filter material within the filter sleeve. Furthermore, a cutting station is provided as a processing station, which is in particular a circular knife.

At least one filter material supply station comprises two rotatably non-concentrically provided discs, each having a hole, wherein the hole in one disk and the disk in the other disk. The fact that the holes are arranged parallel to one another at certain locations allows, for example, a very precise dosing of the granular material. In this case, the dosing is effected, for example, by the size of the holes or by other dosing elements.

If the at least one filter material supply station comprises at least one feed member with holes and / or at least one lever member with holes, a reliable filling of the filter sleeve takes place. .

If at least one filter material loading station comprises at least one first transfer means for loading the filter material into the filter sleeve, a reliable filling of the filter sleeve is possible. If at least one second transfer means is provided which acts as a counter bearing to the at least one first transfer means from the opposite side of the filter sleeve, it is possible to simultaneously fill the filter sleeve from both sides. Either the filter material provided in the center of the filter sleeve can be held centrally, or the filter sleeve can be delivered into the filter material loading station. It is possible to provide at least one filter sleeve in axial alignment with the at least one hole. Furthermore, it is possible to provide at least two holes in axial alignment with the filter sleeve. In this case, it is possible to deliver a large amount of filter material at the same time, whereby a further increase in speed is achieved.

[0034] The object raised objectively is furthermore according to the invention a tobacco comprising a filter material supply device for supplying a filter sleeve and a transfer system for transferring the filter sleeve on a predetermined path. The problem is solved by providing a multi-filter manufacturing system for products in the processing industry, wherein the transfer system is provided with a rotating device for rotating the filter sleeve. This configuration also means, in particular, that the transfer system has a rotating device for rotating the filter sleeve.
The multiple filter manufacturing system according to the present invention allows for quick filling of the filter sleeve with filter material.

The transfer system comprises at least one continuously rotating conveyor for transferring the filter sleeve in the transverse direction. In addition, a processing station is provided with an associated at least one conveyor. If only one conveyor is provided with at least one processing station, a very compact multiple filter manufacturing system is possible. Furthermore, if a number of conveyors are provided, and these conveyors are provided with or without at least one processing station, a modular multi-filter manufacturing system is possible. Most modular multi-filter manufacturing systems are achieved when a number of conveyors are each provided with at most one processing station.

An apparatus for making multiple filters for products in the tobacco processing industry manufactured or sold by the Applicant is a multi-filter of about 1,200 multi-use lengths of two. Manufacturing filters.
With the device according to the invention, the use length of two tubes is about 5,2.
It is possible to produce 00 multiple filters. This makes the advantages of the solution according to the invention particularly clear.

The present invention will be described in detail with reference to an embodiment of the invention illustrated in the accompanying drawings, but the present invention is not limited to this embodiment.

BRIEF DESCRIPTION OF THE DRAWINGS In the drawings, the same reference numbers are used for the same or corresponding features and, therefore, these reference numbers have not been described again.

FIG. 1 shows the transfer station in cross section. The sleeve 11 provided at the inlet of the sleeve supply drum 10 and having the first filter material 19 in the center is moved into the area of the transfer station. The same applies to the filter plug 20 made of, for example, cellulose acetate. The filter plug 20 has a length of, for example, 8 mm. This filter plug 20 is a filter plug
By means of the transfer conveyor 21, for example, the filter plug 2
0 is supplied to the filter plug storage unit 25 by a filter plug drum stored in the storage unit.

In a continuous method step illustrated in FIG. 2, the filter sleeve 11 is in operative engagement with the transfer station and is held in place by the vacuum holes 13 provided in the transfer drum. Furthermore, the ram 18 has already been inserted into the filter sleeve 11 from below. Further, the filter plug 20 transferred by the filter plug conveyor 21 is transferred to the transfer unit, and is held at the position shown in FIG. Furthermore,
Two different granules, a first granule 26 and a second granule 27, are filled in the slider 24 in the predetermined holes 14 for these granules. The amount of granules is determined by the pore size.

The slider 24 is blocked by sliding from left to right in the plane of the drawing and in the opposite direction.

FIG. 3 shows the transfer station in cross section, in which the ram 18 has been moved vertically further upward, so that the filter sleeve 11 is essentially at its upper end at the transfer drum. 12 ends in a straight line with the upper edge. Furthermore, the filter plug 20 is transported by the ram 17 in the axial direction of the ram, ie vertically downwards, into the tube 15 and into the first bore 14 of the slider 23. The circular cutter 28 guided in the guide 29 cuts the filter plug 20 exactly along the upper edge of the slider 23 into two equal filter plugs each 4 mm long. Filter plug 20
The vacuum or suction in the vacuum hole 13 is released in order to transfer the filter into the tube 15 and the filter sleeve 11 into the transfer drum hole 16.

In the next method step shown in FIG. 4, the slider 23 is slid to the left, so that the upper part of the cut filter plug 20 is vertically aligned with the other hole 14 of the slider 23. Parallel. In another method step, not shown, the filter plug 20 is
Is fed into the other hole by means of another filter plug 30 of another material, for example a fleece enriched with granules, cut with a circular cutter and into the two remaining holes 14 of the slider 23. be introduced. FIG. 5 shows exactly how the other filter plug 30 has been introduced into the remaining hole. The first granules 26 have already fallen into the filter sleeve 11 by gravity. In order to achieve the tightest possible filling, the filter sleeve 11 is oscillated or rocked. For this purpose, a vibration generator 44 is provided, which is
The vibration movement is transmitted to the filter sleeve 11 by mechanical contact of the spring plate 44 with the filter sleeve 11.

FIG. 5 shows that the hole of the slider 23 in which the filter plug 30 is present and the hole of the slider 24 in which the granules are present are aligned in parallel with the transfer drum hole 16 and the filter sleeve 11. Oriented, so that the ram 17 can introduce the filter material 30 and 26 into the filter sleeve 11 in the next method step illustrated in FIG. Instead of the method steps as illustrated in FIG. 6, it is possible to introduce the filter material 30 and 26 only to reach the upper edge of the filter sleeve 11, thus further reducing the degree of movement of the ram 17. It is possible.

FIG. 7 shows that after the straight alignment is performed as described above, the hole in which the filter plug 20 is disposed and the hole of the slider 24 in which the granules 27 are disposed correspond to the filter sleeve 11. A method step is shown which is aligned in parallel with the ram 17 so that the ram 17 is ready to introduce material.

FIG. 8 shows that the filter sleeve 11, which is only half filled with filter material, is transferred downward by the lowering of the ram 18 and into the working area of the vacuum holes 13, so that the filter sleeve 11 is again The method steps which are held in a vacuum hole and correspondingly in a housing provided in the transfer drum 12 are shown. As a next method step, the half-filled filter sleeve is fed to a turning drum and then 180 °
The diverted filter sleeve is subjected to the same method steps, so that a total of five times the filter length of the two used lengths is produced. The fivefold filter then contains five different filter materials in this embodiment, which are arranged in segments in the five filters. This material comprises, for example, a first filter material 19 having a length of 8 mm after cutting a filter of two working lengths, a first granule 26 having a height of about 8 mm, a height of about 4 mm. Or 4m
m, a second filter plug 30 having a height of about 8 mm and a closing filter plug 20 having a thickness of 4 mm. Within the framework of the invention, it is possible to use filter plugs with a thickness of 2 mm or less, so that more filter material can be arranged in the segments of the filter sleeve 11.

FIG. 8 further comprises a lead-out drum 50, which leads the half-filled filter sleeve 11 to a turning drum not shown in FIG. The filter sleeve is then turned by 180 ° in this turning drum and is then fed again by the supply drum to the transfer drum 12, whereby the remainder of the filter sleeve 11 is filled.

Within the framework of the invention, it is also possible for the filter sleeve to be turned multiple times in order to load different filter materials at multiple stations. That is, each half of the filter sleeve 11 must be completely filled at the transfer station before they can be rotated.

In order to produce the filter sleeve 11 with the first filter material 19 in the center, it is possible, for example, to adjust the machine involved in the production of the applicant, ie Mmulfi E, accordingly. In order to subsequently bond the subsequently introduced filter plug, the seam bond of the filter sleeve 11 is folded back and bonded with a hot melt adhesive based on PVA-adhesive (polyvinyl acetate-adhesive). For this purpose, the cooling web bonding the seam is replaced by a heating web. The supply of adhesive is changed appropriately. That is, the filter sleeve is bonded with an adhesive that does not cause the adhesive bond to be released by heating.

The segment bonding, ie the bonding of the filter segments to be joined later, is carried out by applying a hot-melting adhesive strip on the paper, and before the filter sleeve is deformed, into the filter sleeve. After the filter segments have been introduced into the filter sleeve, which has a trace of cooled hot melt adhesive, the entire filter sleeve is also heated by thermal contact or by a suitable energy-rich radiation, for example microwave radiation. This melts the hot melt adhesive and bonds the segments.

FIG. 9 shows another embodiment of the delivery device according to the invention, in which four different filter materials can be delivered simultaneously into the filter sleeve. It is. The filter sleeve otherwise comprises, for example, a paper sleeve 37. In order to transfer the four different filter materials, a third slider 41 and a fourth slider 42 are provided in addition to the first slider 23 and the second slider 24. In the third slider 41, for example, the soft element 30 is introduced,
The granules 26 are introduced into the fourth slider 42.

Within the framework of the invention, it is possible to increase the number of holes in the slider 24 according to the embodiment of FIGS. 1 to 4 to four, so that these four holes are filled with the corresponding granules. No other granule filling is necessary after turning and rotating the filter sleeve. In the embodiment of FIGS. 1 to 8, the filter plugs 20 and 30 have already been stored, so that after filling of one side of the filter sleeve 11, a further filter plug is introduced into the slider 23. do not have to. Of course, this is also true in the embodiment according to FIG.

FIG. 10 shows an upper region (FIG. 10).

Two discs that are offset from the two centers, a first disc 31 and a second disc 32, are shown. In this case, the first disk 31 is provided above the second disk 32. FIG. 10a shows the device in plan view. Both disks 31 and 32 have holes 14. Granules 26 are filled into these holes. For this purpose, granules 26 are supplied by a granule filling device 51.

The first disk 31 rotates on the disk 32 in a direction opposite to the clock hand, and this disk 32 also rotates in the clockwise direction in this embodiment. The second disk 32 is provided with a filter sleeve 11 below the disk. These filter sleeves 1
1 is held at an appropriate position by a usual holding device. The granules whose volume fraction is predetermined by the size of the holes move in the direction of the loading zones 38a-38b in a direction opposite to the clock hand. The filter sleeve 11 provided below the second disk 32 is moved accurately. At the loading position 38, the holes of both disks are aligned in a straight line. The granules are loaded into the filter sleeve by gravity, as shown in FIG. 10b. By means of the excellent granule feeding station according to the invention, ie the granulation dispensing station, the proportion of granules and the proportion of granules introduced into the filter sleeve are realized in a particularly simple manner. The large loading zones 38a-38b allow the disks 32 and 31 to rotate at high speeds and correspondingly increase the production speed. In order to achieve the densest possible filling of the granules, in this embodiment a vibration generator 44 and a spring plate 43 are provided, by means of which the filter sleeve is brought into contact with the granules 26 during or after filling. Vibrated together. The vibration generator 44 is an electromagnet having a mass that reciprocates at a frequency of 50 Hz, in particular.

Only one main drum 100 is shown, in which all processing stations for filling the filter sleeve 11 can be carried out. Immediately before the take-off for the filled and finished sleeve, a heating element is provided which is operatively connected to the sleeve, whereby the hot element applied to the inside of the paper sleeve in the preceding method step. Induces adhesion of the melt adhesive. This keeps the inserted filter material in that position. FIG. 11 shows a spring plate 43 that transmits vibration to a sleeve filled with granules.

FIG. 12 schematically shows another embodiment according to the present invention. The filter sleeve 11 is supplied to a transfer drum 12 by a sleeve supply drum 10. This is also shown schematically in FIG. 13 at position a). In position b), the filter sleeve 11 has been moved somewhat further upward, and the ram 17 has also been moved upward. In the course of the process up to position e), the ram has been moved further upward. In position f) the filter plug 20 is supplied by a filter plug conveyor 21--in this embodiment a drum. This step is schematically illustrated in FIG. 13 at position f).
