- the rotational movement of the filling element 112 is synchronised with the rotational movement of the receiving drum 22 so that the cavity 113 meets the flute 28 to transfer the rod MA.
- the movement of the filling apparatuses 111 and 111' is synchronised so that they feed the rods MA alternately into the successive flutes 28.
- the feeding module may be provided with any number of the feeding channels 110, in which case successive flutes are cyclically filled by successive filling apparatuses 110.
- the feeding module 20 is provided with a filling sensor 115 for checking the presence of the rod MA in the flute 28 of the receiving drum 22, the filling sensor 115 being situated at the lateral surface of the receiving drum 22, the measuring area of the filling sensor covering at least one flute 28 of the receiving drum 22.

- the feeding apparatus 118 When the absence of the rod MA in the flute 28 is detected by the filling sensor 115, the feeding apparatus 118 will be actuated so that the filling apparatus 119 makes a rotation to transfer the rod MA to the flute 28 of the receiving drum 22 when the empty flute 28 is within the operating area of the filling apparatus. A repeated absence of the rod MA will indicate that one of the feeding channels 110 is blocked.
- FIG. 4 shows the second embodiment of the feeding module provided with four feeding channels 110, the total feed capacity through the feeding channels 110 being equal to the required capacity of the receiving drum 22 which is dependent on the capacity of the downstream equipment in the production process.
- Each of the feeding channels 110 is provided with a blockage sensor 114 which checks whether the flow of the rods through the feeding channel 110 is taking place correctly. If a blockage in the feeding channel 110 is detected, a controller S receives a blockage detection signal.

- the controller S receives information that some feeing channel 110 is not working properly and not all flutes 28 of the receiving drum 22 are filled based on the signal from the filling sensor 115 or based on the signal from the blockage sensor 114, these signals may be collectively referred to as an empty flute signal, i.e. the controller receives information that an empty flute has already occurred or will occur.
- a blockage of one of the channels can be seen in Fig. 4 , namely every fourth flute 28 on the receiving drum 22 is unfilled.
- the feeding apparatus 118 is adapted to fill the single flutes 28 that have remained unfilled due to a momentary disturbance in the operation of the feeding channels 110. Furthermore, the feeding apparatus 118 is adapted to replace the feeding of any of the feeding channels 110, i.e. it is adapted to continuously feed the rods MA in order to replace the continuous feeding of the rods MA carried out by any of the feeding channels. For example, in case a blockage occurs in one of the feeding channels 110, the feeding apparatus 118 temporarily takes over the operation of such feeding channel 110 which has been blocked, until it is unblocked, so that the supply module 20 can operate continuously. Thus, it is possible to temporarily disable one of the feeding channels 110 when the feeding channel 110 itself is damaged and for the feeding apparatus 118 to take over the operation of such feeding channel 110 while the damaged feeding channel 110 is being repaired.

Description
- The object of this application is a feeding module for feeding segments, an apparatus for manufacturing multi-segment articles and a method of feeding the segments for the manufacturing of multi-segment articles.
- At present, the tobacco industry manufactures rod-like articles comprising a plurality of elements, namely tobacco elements containing tobacco or material containing processed tobacco, filter elements, elements containing flavouring substances, distance elements used for example to cool tobacco smoke. In this application, these various elements will be referred to as segments and articles containing such segments as multi-segment articles or multi-segment rods.
- An apparatus for assembling groups of filter segments wherein the rods are fed from a hopper by means of a multi-channel system. For example, the publication
WO 2014188306 describes an apparatus feeding the rods from a hopper provided with several independent channels feeding a receiving drum. - In tobacco industry machines, there is a need to convey rod-like articles in single-layer streams or multilayer streams, and there is a need of temporary bulk storage of such articles in hoppers. There is a need for semi-finished products within the production process to be conveyed in such a way that their quality is not reduced. When designing the hoppers as well as the mass flow channels, it must be taken into account that this type of storage and conveying of articles carries a risk of deformation of the articles. The risk of deformation of the articles arises, among others, when the rod-like articles are received from the hopper into the flutes of the receiving drum in the machines for manufacturing multi-segment rods because the flutes of the receiving drum move into the lowest area of the hopper where the pressures are highest. A solution to the problem is to use multiple channels to feed the articles to the receiving drum. However, there is a need for an apparatus for multi-channel feeding of the rods from the hopper which ensures that the flutes are filled up to highest possible extent when one of the conveying channels becomes blocked or out of service.
- The object of the invention is a feeding module for feeding segments for the manufacture of multi-segment articles adapted to cut a rod into segments and to feed the segments, comprising a hopper for storing the rods, a receiving drum for receiving the rods from the hopper, a conveying drum for conveying the rods, a cutting head, situated at the conveying drum, for cutting the rod into individual segments, a shifting drum for varying the mutual position of the segments, an aligning drum for forming at least one stream of the segments. The feeding module is characterised by being provided with feeding channels extending from the hopper to the receiving drum, and a filling sensor generating an empty flute signal when the flute of the receiving drum remains empty in the measuring area of the filling sensor, furthermore, the feeding module is adapted to feed the rod into the empty flute of the receiving drum by means of a feeding apparatus situated downstream of the filling sensor in response to the empty flute signal of the receiving drum.
- The feeding module is characterised in that the feeding channel is provided with a blockage sensor, and the empty flute signal is generated by the flute filling sensor of the receiving drum or the blockage sensor of the feeding channel.
- The feeding module is characterised in that the feeding channels are gravity channels.
- The feeding module is characterised in that the walls of the feeding channels are formed by belts forcing the movement of the rods towards the receiving drum.
- The feeding module is characterised in that the feeding apparatus is adapted to continuous feeding with the rods to replace the continuous feeding with the rods carried out by any of the feeding channels.
- Furthermore, the object of the invention is an apparatus for manufacturing multi-segment articles, comprising at least two feeding modules according to the invention for feeding the segments formed by cutting the rods, an assembling unit provided with drum conveyors for receiving the segments from the feeding modules and forming a segment group, a first wrapping module for feeding a section of the first wrapping material and wrapping a segment group so as to form a multi-segment rod, a cutting unit for cutting the formed rod into half multi-segment rods, an additional feeding module for cutting an additional rod and feeding additional segments between half multi-segment rods according to the invention, a second wrapping module for feeding a section of a second wrapping material and wrapping a group including the additional segment and the half multi-segment rods so as to form the multi-segment rod.
- The object of the invention is also a method of feeding the segments for the manufacture of multi-segment articles, comprising steps wherein the rod is fed to the hopper, the rod being a multiple of the segment, the rods are conveyed through at least two feeding channels to the receiving drum, the rod is received from the channel into the flute of the receiving drum, the rod is transferred from the flute of the receiving drum to the flute of the conveying drum, the rod is cut into individual segments when conveying the rod in the flute of the conveying drum by means of the cutting head situated at the conveying drum, the mutual position of the segments on the shifting drum is varied, at least one stream of the segments is formed on the aligning drum. The method according to the invention is characterised in that, in addition, the presence of the rod in the flute of the receiving drum is checked by means of the filling sensor, the empty flute signal is generated by means of the filling sensor when the flute of the receiving drum remains empty in the sensor's measuring area, and the rod is fed into the empty flute of the receiving drum by means of the feeding apparatus situated downstream of the filling sensor in response to the empty flute signal of the receiving drum.
- An advantage of the invention is that, in the process of supplying the rods through the feeding channels, it is possible to temporarily disable one of the channels while maintaining the expected performance of the machine. The use of channels in which the flow of individual articles is ensured provides the possibility to check the quality of individual segments, for example to check the length of the segments or also the quality of the segment front since the access to each flowing article is ensured. In addition, it is possible to check the length of the rods. In the case of the supply of multi-segment rods, it is also possible to check the rods comprehensively. The supply of the rods through channels makes it possible to reduce the pressure on the lowest lying rods in the hopper, thus to eliminate the risk of deformation of the rods. In addition, the rods within the channel have fewer points of contact with adjacent rods so the likelihood of rods sticking together is reduced.

- An
apparatus 1 for manufacturing multi-segment articles comprises an assemblingapparatus 10, afirst wrapping module 40, acutting unit 50, areorienting unit 60, anadditional feeding unit 70, and a second wrapping module 80 (Fig. 1 ). - The assembling
apparatus 10 comprises at least twofeeding modules 20 and an assemblingunit 30, in the embodiment shown, the assemblingapparatus 10 comprises fourfeeding modules feeding module - The
feeding module 20 comprises ahopper 21 for the rods MA, areceiving drum 22 provided with circumferentially arranged flutes in which the rods MA from thehopper 21 are situated and drums for forming a stream of segments A formed by cutting the rod MA. The rods MA from thehopper 21 are supplied to the receivingdrum 22 by means of feeding channels situated between thehopper 21 and the receivingdrum 22, such feeding channels are discussed below in this description. The receivingdrum 22 transfers the rods MA to the conveyingdrum 23. At the conveyingdrum 23, there is situated acutting head 24 which is provided with one or morecircular knives 24A for cutting the rods MA. Thefeeding module 20 comprises at least one shiftingdrum 25 and at least one aligningdrum 26. The shiftingdrum 25 may also be referred to as cascading drum where successive segments are arranged in successive flutes of this drum. - The
feeding module 20 feeds segments A in the form of at least one stream. In the embodiment shown, in thefeeding modules unit 30. - The rods MA stored in the
hopper 21 are supplied through the feeding channels so as to fill theflutes 28 arranged circumferentially on the receivingdrum 22 during the rotation of this drum (Fig. 3 ). The rods MA are held in theflutes 28 by means of a vacuum supplied through holes in the bottom of theflute 28. The receivingdrum 22 conveys the rods MA at the point of transfer X to theflutes 29 of the conveyingdrum 23 in which the rods MA are also held by means of a vacuum. The rod MA being a multiple of the segment A is cut into individual segments A, whereas the segments A formed from one rod MA form a group G (Fig. 3a ). Subsequent groups G of the segments A are transferred to the shiftingdrum 25 and further to the aligningdrum 26 to form a stream of individual segments A. - The
feeding module 20 is provided with feeding channels supplying the rods MA from thehopper 21 to theflutes 28 of thereceiving drum 22. In the first embodiment shown inFig. 3 , the feeding module is provided with two feedingchannels 110, the feeding channels being gravity feeding channels, at the end of the feedingchannel 110 there is situated a fillingapparatus 111 which comprises arotating filling element 112 having twocavities 113, with the rod MA being placed in thecavity 113. The rotational movement of the fillingelement 112 is synchronised with the rotational movement of the receivingdrum 22 so that thecavity 113 meets theflute 28 to transfer the rod MA. The movement of the fillingapparatuses 111 and 111' is synchronised so that they feed the rods MA alternately into thesuccessive flutes 28. The feeding module may be provided with any number of the feedingchannels 110, in which case successive flutes are cyclically filled bysuccessive filling apparatuses 110. Thefeeding module 20 is provided with a fillingsensor 115 for checking the presence of the rod MA in theflute 28 of the receivingdrum 22, the fillingsensor 115 being situated at the lateral surface of the receivingdrum 22, the measuring area of the filling sensor covering at least oneflute 28 of the receivingdrum 22. In addition, thefeeding module 20 is provided with afeeding apparatus 118 which comprises a fillingapparatus 119 situated at the end of thechannel 120 departing from thehopper 121. Thefeeding apparatus 118 is situated downstream of the filling sensor considering the direction of conveying of the rods MA in theflutes 28 of the receivingdrum 22. When the absence of the rod MA in theflute 28 is detected by the fillingsensor 115, thefeeding apparatus 118 will be actuated so that the fillingapparatus 119 makes a rotation to transfer the rod MA to theflute 28 of the receivingdrum 22 when theempty flute 28 is within the operating area of the filling apparatus. A repeated absence of the rod MA will indicate that one of the feedingchannels 110 is blocked. - Any number of feeding
channels 110 may be applied,Fig. 4 shows the second embodiment of the feeding module provided with four feedingchannels 110, the total feed capacity through the feedingchannels 110 being equal to the required capacity of the receivingdrum 22 which is dependent on the capacity of the downstream equipment in the production process. Each of the feedingchannels 110 is provided with ablockage sensor 114 which checks whether the flow of the rods through the feedingchannel 110 is taking place correctly. If a blockage in thefeeding channel 110 is detected, a controller S receives a blockage detection signal. As in the previous embodiment, thefeeding module 20 is provided with the fillingsensor 115, whereas the fillingsensor 115 checks the presence of the rod MA in theflute 28 of the receivingdrum 22. Thefeeding module 20 may be provided with either theblockage sensor 114 or the fillingsensor 115, or may be provided with both such sensor. The controller S receives information that somefeeing channel 110 is not working properly and not allflutes 28 of the receivingdrum 22 are filled based on the signal from the fillingsensor 115 or based on the signal from theblockage sensor 114, these signals may be collectively referred to as an empty flute signal, i.e. the controller receives information that an empty flute has already occurred or will occur. A blockage of one of the channels can be seen inFig. 4 , namely everyfourth flute 28 on the receivingdrum 22 is unfilled. Thefeeding apparatus 118 is adapted to fill thesingle flutes 28 that have remained unfilled due to a momentary disturbance in the operation of the feedingchannels 110. Furthermore, thefeeding apparatus 118 is adapted to replace the feeding of any of the feedingchannels 110, i.e. it is adapted to continuously feed the rods MA in order to replace the continuous feeding of the rods MA carried out by any of the feeding channels. For example, in case a blockage occurs in one of the feedingchannels 110, thefeeding apparatus 118 temporarily takes over the operation ofsuch feeding channel 110 which has been blocked, until it is unblocked, so that thesupply module 20 can operate continuously. Thus, it is possible to temporarily disable one of the feedingchannels 110 when the feedingchannel 110 itself is damaged and for thefeeding apparatus 118 to take over the operation ofsuch feeding channel 110 while the damagedfeeding channel 110 is being repaired. - In the third embodiment shown in
Fig. 5 , thefeeding module 20 is provided with fivefeeding channels 110. Similar to the previous embodiment, the feeding apparatus can both take over the operation of the feeding channel and fill up individual missing rods MA. The feeding module in the fourth embodiment shown inFig. 6 is provided with three feedingchannels 116, the feedingchannel 116 in this embodiment having walls formed bybelts 117. It is possible to embody a feeding module with a greater number of feeding channels. Similar to the above-discussed embodiments, the fillingelements 112 of theindividual feeding channels 116 are synchronised with one another and with the receivingdrum 22. The functions of thefeeding apparatus 118 are similar. - An assembling

The reorientingmodule 60 may be provided with rotating drums known in the tobacco industry, which, in addition to circumferential conveying, rotate the conveyed rod-like articles around axes which are substantially perpendicular to the circumferential surface. The reorientingmodule 60 is adapted to vary the positioning of the rod-like articles R1 and R2 relative to each other. As a result of the operation of the reorientingmodule 60, the rods R1 and R2 are reoriented so that the segments D which are the ends of the rods R1 and R2, initially oriented away from each other, are oriented towards each other, while the half segments B, arranged opposite to the segments D in the rods R1 and R2, initially oriented towards each other, are oriented away from each other. In addition, the rods R1 and R2 become coaxially situated, and there will be a gap maintained between the rods R1 and R2. - The
