Description

Device for feeding filters.

The invention relates to a device and a procedure for feeding rod-shaped items of the tobacco industry, especially filter rods or filter units, from a reserve warehouse, being able to extract or optionally extracting items from the warehouse (40, 44) of reservation by means of an extraction device (11, 21) respectively. The invention further relates to a machine of the tobacco industry, especially a machine for placement of filters or a machine for the manufacture of filters.

In the document GB-A-2267021 describes a machine for the placement of filters, in which the filter rods are respectively extracted from two stores. After removing one First filter rod, this filter rod is cut in the center and separates in axial transverse direction. A second Filter rod, coming from the other warehouse, is inserted to continuation in the center between the sections of the first rod Filter Then, this arrangement of the filter rod is short, staggered and moves respectively in drums This process of cutting, staggering and displacement of the filter units are repeated and therefore performed twice total. The combined filter, obtained from two rods other than filter, it is then transferred to a drum grouper with cigarette rods.

In the patent EP-B-0674853 (in correspondence with US-5984851) also describes a device for feeding filters in a machine for filter placement. In this case, filters or units of filter are cut, staggered and also move several times consecutively on the drums. The device power supply made known allows to feed simple filters or Dual to cigarette groups.

This patent also describes the placement Optional single or double filters between pairs of columns tobacco separated in axial longitudinal direction. To that end, the filter placement machine has two warehouses reserve of filter rods, as well as two drum trains for remove, transport and process the filter rods. Likewise, a third drum train is planned, in which the first drum trains for insertion of filters between tobacco columns It is also provided a device adaptation to adapt the first two drum trains to Dual filter or single filter operation. According to technical instruction, the first two drum trains are always  working together.

In the document DE-A-10146019 also describes a device for manufacturing multi-segment filters that are It consists of different modules or units. In case of a unit of hard filter simultaneously remove hard filter elements from a reserve store through two feeding ducts.

In the document DE-A-10146992 further describes a transfer device, as well as a mold drum for the transfer of hard filter elements. Also, the document DE-A-19748074 unveils a device to flexibly supply filter rods to several cigarette machines, with a warehouse of filters between a machine for the manufacture of filter rods and a machine for feeding filters.

In addition, the document CA-A-954001 unveils a procedure for the distribution of filters manufactured from from a filter store, feeding filter rods to different filter processing machines from a warehouse filters For the feeding of the processing machines of filter, filter rods are classified by a type of centrifuge

Starting from this state of the art, the The present invention aims to provide a system of simple and variable feeding of filter rods from a reserve warehouse, in which the expense and adaptations in case of a product change should be as small as possible.

In the case of a device for Industry rod-shaped article feed tobacco company, especially filter rods or filter units, with a reservation store for items, in which they are provided for at least two extraction devices for articles and in which the items can be extracted from the reserve warehouse optionally or alternatively in each case by means of a device extraction, is proposed as the first solution of the objective that in the reserve store an ejection device is provided for feeding the items to an extraction device respectively. When there are at least two extraction devices in the warehouse, which are operated alternately, it is possible extract from the reserve warehouse two different types of rods filter. Thus, for example, in a first production cycle in a filter placement machine filter rods are removed from the warehouse and cut into four. After a change of production, for example, the longest filter rods are extracted from the reservation store by the other device Extraction and cut into six. Therefore, the device according to the invention enables the extraction of length filter rods different from the same filter store, without changing the format in The feeding device. In this way they can be used alternatively two different filter formats in the device of feeding.

For proper feeding of items in the reserve store to an extraction device is provided an ejection device for items in the reserve warehouse. The ejection device enables the access to an extraction device respectively while the other extraction device does not stock up on items, since that the ejection device serves at the same time as an element lock

According to an advantageous variant, the warehouse of Reserve is configured or can be adapted for at least two types of article, so that at least two different formats of filter, determined previously, are housed in the warehouse of filters For this purpose, for example, the front or rear wall of the reserve store or filter store are arranged so movable, so rods can be introduced and processed filter of different length. Especially the front wall and Back of the reserve warehouse can be moved or moved by at least one preferably motor drive.

To automatically fill the warehouse Reserve with items in the form of a rod or filter rods, the Reserve store is configured with a receiving station of articles. A station receiving such items is known with the name "Filtromat" of the HAUNI firm Maschinenbau AG.

The reservation store is also configured preferably by means of an inclined tank, so that the inclined tanks filled with filter rods are used as Reserve deposits for the reserve warehouse.

Another device configuration consists of that for the items, extracted by each device of extraction, a transport section is provided respectively individual, so that after extraction, the items transported have a drum operation or a individual transport path in the transport direction of the articles. For this purpose, each individual transport section advantageously comprises at least one conveyor element.

As a transport element it is planned especially an extraction drum and / or a cutting drum and / or a stepping drum and / or a sliding drum and / or a acceleration drum, so that in a desired combination or default operation is conveniently configured drum or drum arrangement for sections individual transport.

It is also advantageous that in the direction of transportation of items, following sections individual transport, a transport section is planned common for items with at least one conveyor element. Through the common transport section they are still transported, by example, filter units or filter plugs already cut and these they are inserted between pairs of columns of tobacco separated in axial longitudinal direction. This configures a default drum operation for items extracted in each case.

It is further preferred that for each element conveyor is provided an individual drive.

According to an alternative embodiment, it is planned a drive in each case for several elements conveyors, so that by means of the common drive It has a drive unit that drives synchronously, by example, several drums of a transport section.

In order to also enable a switching from a first extraction device to the second extraction device in case of a change of product can vary the position of the ejection device In the reserve warehouse.

For this purpose it is advantageous that the device eject is configured by a guide element, especially a guide plate, or by a blind or similar that have the function of an ejection device or a device blocking.

The invention is further refined by being configured the eject device using a tape conveyor or conveyor element.

The conveyor belt or the element conveyor are especially reversible with respect to the direction transport to alternately transport the items to the extraction zones or the extraction drums. Due to the reversibility of the conveyor elements can be switched quickly from one extraction zone to the other zone of extraction.

The objective is also achieved through a tobacco industry machine, especially a machine for the placement of filters or a machine for the manufacture of filters, which is equipped with a feeding device previously described. In order to avoid repetitions it is referred expressly to the preceding explanations.

In a procedure for feeding rod-shaped items of the tobacco industry, especially filter rods or filter units, from a reservation store for items, in which items are extracted from the reserve warehouse alternately in each case by one of at least two extraction devices, it is proposed as another solution that the items in the reservation store are guide alternatively to an extraction device respectively by means of an expulsion device.

       \ newpage
    

For this purpose it is also proposed that the warehouse of reservation suits one type of item in each case, achieving thus an easy change of format or change of article in the warehouse of reservation. The adaptation can be done, for example, by adjustment of the width of the warehouse walls.

In addition, the reservation store is configured by an inclined deposit, so that the items are removed from the inclined tank.

For automatic filling of the warehouse reservation is also proposed that the items are carried in a receiving station of items to the reserve warehouse.

In a preferred embodiment, the items removed by the extraction device are transported in an individual transport section respectively by less a conveyor element.

It is also advantageous that the articles are transport after the individual transport section in a common transport section by at least one element conveyor.

The conveyor elements are operated preferably in each case by an individual drive. Several conveyor elements are operated alternately by means of a drive respectively.

To achieve alternative operation or change of format or change of extraction devices, it the position of the ejection device in the storage warehouse varies reservation.

According to a preferred variant of the procedure it is proposed that items be transported alternately by means of the ejection device to an extraction tank in each case. For this purpose, the ejection device is preferably configured as a reversible conveyor element or as a reversible conveyor belt in its direction of transport.

The invention has the advantage that with a warehouse and at least two extraction devices can be processed  different formats of filter rods in a machine, without having extensive modifications have to be made in the reserve warehouse. Transport devices or drums are also provided. default transport after extracting the items, so that items are reliably removed from the  reserve store when switching to the other operation of drum.

Figure 1 shows the front view of a machine for placing filters of the MAX model of the firm Hauni Maschinenbau AG. This machine features the following particularities: An input drum 111 transfers the columns of tobacco, produced by a cigarette rod machine, to a stepping drum 222 which delivers to a grouping drum 133 tobacco-fed columns two by two respectively with an intermediate space between the columns of tobacco.

The filter rods pass from a warehouse 40 to an extraction drum 60, are cut here in filter caps with a double length of use, are staggered in a drum 70 stepping, are aligned by a drum 80 of displacement in a row of plugs located consecutively and they are deposited by means of a drum 90 of acceleration in the spaces Intermediate rows of cigarettes in the grouping drum 133. Groups of tobacco column, filter plug and column tobacco are received and displaced jointly by a drum tilting 110.

Through warehouse 40 and drums 60, 70, 80, 90 a feeding device 50 for the rods is formed Filter

A band 120 of wrapping paper, unwound of a bobbin 130 of wrapping paper, is glued by a glueing device 140 and then cut into sheets small wrap in a cutting device 160 on a drum 170 suction by means of the blades of a drum 180 of blades Small separate wrapping sheets join the groups of tobacco column, filter plug and tobacco column in the tilting drum 110 and wrap around the groups of Cigarette filters in a 190 drum drum.

Cigarettes made of double filter are they are fed by a transfer drum 210 to a drum 220 cutting, in which filter cigarettes are made individual when the filter caps are cut centrally. A investment device 230 reverses the row of cigarettes with filter and directs it simultaneously to the continuous row of Cigarettes with non-inverted filter. Cigarettes with filter they pass through a test drum 240 to an output drum 260. A distribution drum 280, which interacts with a drum 270 of brake, distribute the cigarettes with filter on a 290 tape of distribution.

Figure 2a shows a first example of embodiment of a feeding device 50 according to the invention,  in which the filter rods are guided towards the lower zone left for the extraction of the warehouse 40. To this end, in the feeding zone 41, in the right zone of zone 41 of supply, a guide plate 42 is arranged. The guide plate 42 It is drawn with dashed lines in Figure 2a and in the following figures. The work positions or positions of the Guide plate 42 have an eject function. In this way, the Filter rods are guided from the warehouse 40 towards the area left of the feed zone 41 while the zone bottom right of feed zone 41 is locked.

In the case of the embodiment shown in figure 2a, in the lower area of the warehouse 40 are provided two extraction zones to extract filter rods.

An extraction drum 11 is provided in the lower area for the extraction of filter rods on the side left, so that the filter rods are removed from the warehouse 40 and cut into double length filter caps of use by one or several cutting blades 12. The plugs of Cut filter are then transferred from drum 11 of extraction to a stepping drum 13, in which the Filter plugs are arranged in a staggered manner. The plugs of Stepped filters are then transferred to a drum 14 of displacement, in which the plugs are arranged one behind the other in a row Then the filter plugs are transferred to an acceleration drum 15.

Filter plugs cut and arranged one behind another in a row in axial transverse direction is transferred from the acceleration drum 15 to the drum 31, 32 of transfer and are transported to drum grouper 133 (see Figure 1).

In this case the section of right transport, consisting of an extraction drum 21, one or two cutting blades 22 arranged in the extraction drum 21, a scroll drum 23, a step drum 24 and a acceleration drum 25, since the feed zone 41 in the right side is separated from the guide plate 42, so that the Filter rods do not pass to the extraction zone with the drum 21 extraction. The acceleration drum 25 works at the same time to be able to transport the drum filter caps 15 of acceleration by transfer drum 31 to drum 32 of transfer, without colliding with the acceleration drum 25.

If the product is changed, the working position of the guide plate 42 (figure 2a), so that the left zone of the feeding zone 41 is blocked by the guide plate 42, which is represented in the figure 2b The extraction of the filter rods is then performed by the right transport section with the drums 21, 23, 24, 25. Filter caps, cut from the removed rods of filter, are arranged one behind the other in a row in longitudinal transverse direction on the drum 25 of acceleration and are passed to the drum drum 133 by the drums 31, 32 transfer.

By means of the drums 11, 13, 14 and 15 an individual transport section is configured for the filter rods or the filter plugs removed from the left side. This individual transport section is identified by reference L. When the filter rods are removed and the filter plugs, cut from the filter rods, are transported in the left transport section L (see Figure 2a), the filter rods are then transfer to transfer drums 31, 32. In this case, the acceleration drum 25 is also further operated together with the transfer drums 31, 32, so that the filter caps, transported in this transport path, do not collide with the acceleration drum 25, since in The transport path of the filter plugs from the acceleration drum 15 to the transfer drum 32 is arranged between these the drum 25
acceleration.

The right transport section for filter rods removed from the right side of the store 40 or The cut filter caps is identified with the reference R and it is composed of drums 21, 23, 24 and 25. When transporting the filter rods or filter plugs in section R of right transport (see figure 2b) the drums are not operated 11, 13, 14, 15 of the left transport section L, since the filter caps are transferred directly from drum 25 of acceleration by the drum 31 transfer to the drum Next 32 transfer.

For the transfer of the cut plugs of filter is also provided a common transport section for both sections L and R transport, which is composed of drums 31, 32 transfer and is identified with the reference G.

Depending on the filter format or the desired cigarette format in a machine for placing filters are removed filter rods from warehouse 40 per section Left transport L (see figure 2a) or by section R of right transport (see figure 2b). If the extraction or the transport of the filter caps take place by one of the two L or R sections of transport, the elements are actuated corresponding conveyors of the transport section L or R, while the conveyor elements of the other section L or R of transport are not activated at least partially, that is, the conveyor elements are completely or only of partial way at rest.

A machine for placing filters, already existing, can be retrofitted with the power device 50 shown in figures 2a, 2b (see figure 1), so that clearly increases the use of a machine for placement of filters revalued in this way, since it is facilitated largely a product change in the machine for the filter placement.

As warehouse 40 or reserve warehouse they are used in the embodiments of figures 2a and 2b deposits inclined full with filter rods.

In figures 3a, 3b is represented respectively an embodiment example in correspondence with the  Figures 2a, 2b, further presenting the device 50 of feeding of figures 3a, 3b a receiving station 45 of filters that receives filter rods from a filter supplier not shown here and enter them laterally in feed zone 41 or in warehouse 44 of filters A known filter receiving device is known as the name "Filtromat" of HAUNI Maschinenbau AG.

How filter rods are introduced by the receiving station 45 of filters, the guide plate 42 is arranged horizontally to remove the filter rods by the left transport section L (see figure 3a). Figure 3b shows the operating status of the device 50 of supply, in which the filter plugs are removed by the right transport section R of the filter store 44 and cut into filter caps that are transported by drums 21, 23, 24, 25 to transfer drums 31, 32. The guide plate 42 is arranged in this case so that the area left of feed zone 41 is locked.

Another embodiment of a device 50 of feeding according to the invention is represented in the figures 4a and 4b. The working positions of the guide plate 42 as ejection device are drawn in the two figures respectively.

Unlike the embodiments represented in the preceding drawings, in section G of common transport is provided an acceleration drum 33 that groups the functionality of the acceleration drums 15, 25 (see figure 2a) and of the two transfer drums 31, 32. He Acceleration drum 33 sends the filter caps to the drum grouper 133.

In figure 4 it is represented in addition to schematic way that the drums 11, 13, 14, 21, 23, 24, 33 are operated in each case by an individual drive. He individual drive for the respective drums is identified with reference number 35.

A concept is represented in Figure 4b alternative drive for drums 11, 13, 14, 21, 23, 24. In this case, in section L of transport left is a common drive 36 is provided for the drums 11, 13 and in the right transport section R is configured a drive common 37 for drums 21, 23 and 24. Like drum 14 of the L section of left transport works at a time to avoid collisions with filter plugs, which are transported during extraction and transport in the right transport section R and are then transferred to the acceleration drum 33, the drum 14 and the acceleration drum 33 are driven by a common drive 38.

Figure 5 shows a fourth example of realization of a feeding device 50. In zone 41 of supply plates 46, 47 are arranged towards the inside and down to facilitate rod removal of filter of the reserve store 44 towards the drums 11, 21 of extraction. In the lower zone of the feeding zone 41 is arranged a conveyor belt 48 that carries out the transport horizontal and that carries the filter rods fed towards the drum 11 or 21 extraction. To this end, to the tape conveyor 48 is assigned a drive 49 that allows switch or reverse the tape transport direction conveyor 48. In this way, the filter rods are fed  alternatively to the extraction drums 11 or 21, in dependence on the transport section, for which they are transported the rods or filter caps.

If the conveyor belt 48 carries the filter rods to the left side, the filter rods they are housed in the extraction drum 11, which rotates in the direction counter clockwise, and cut into filter caps by means of the cutting blade 12. After transferring the filter caps to the stepping drum 13, the plugs filter are placed stepwise and transferred to drum 14 of displacement, in which the filter plugs are arranged one behind another in a row.

If the transport address of the conveyor belt 48, the filter rods are removed by the extraction drum 21 which rotates in the direction of the needles of the clock and after cutting into filter caps with the blade 22 They are fed by means of the drum 23 which moves to the stepping drum 24. Then the filter plugs arranged one behind the other in axial transverse direction is transferred from the stepping drum 24 to a drum 26 of transfer, so that the filter caps transported in the right transport section R is transferred to the common drum 32 transfer. The filter caps are transported from the transfer drum 31 to an acceleration drum 39.

If the filter caps are transported in the L section of transport left, the filter plugs are they also transfer to transfer drum 31, being in operation at the same time the transfer drum 26, so that the filter plugs can be transported from the left section of transport to the acceleration drum 29, without colliding with the transfer drum 26.

In figure 6 it is represented by sections a section of the embodiment shown in the figure 4b In figure 6a a cut line is also drawn I-I. A corresponding plan view from above the filter store or the feeding device at along the line drawn I-I is represented in cross section in figure 6b. Here you can see that extraction drums 11, 21 are arranged rotatably in corresponding bodies 17 or 27 of control. The bodies 17, 27 of control are arranged on the machine MS side of the filter feeding device 50.

The filter store 44 also has a horizontally movable rear wall 51 and a front wall 52 also movable horizontally. The front wall 52 and the rear wall 51 of the store 44 of filters are crossed by guides 53, 54 in the form of rods, so that the rear wall 51 and the front wall 52 can be adapted to the length of the filter rods to be housed in the filter store 44 (see figure 6a). The front wall 52 and the rear wall 51 of the Filter store serve as a guide for the rods of filter.

In order to vary the distance between the wall front 52 and rear wall 51, guides 53, 54 are mounted, for example, rotatably so that by the rotary guide 53 moves the rear wall 51 or by the rotary guide 54, the front wall 52 in the form of a gear thread or spindle drive. For this purpose they are provided in each case individual motor drives for guides 53, 54

In correspondence with the length of the Filter rods housed in the filter store 44 is regulated the distance between the rear wall 51 and the front wall 52 as well as in correspondence with the width of the extraction drum 11 or of the extraction drum 21, so that the filter rods they stay safely and reliably without filter rods located transversely and conveniently removed to continuation of the store 44 of filters.
