Definitions

  • the invention relates to a device for producing a filter rod for the tobacco processing industry from a filter material comprising a transport nozzle that can be charged with compressed air and a guide device which is arranged downstream of the transport nozzle in the conveying direction of the filter material, the filter material being guided or guided through the transport nozzle and the guide device .
  • the invention thus relates to the field of filter production, in particular the production of filters with inserted additional elements or objects, for example liquid-filled capsules. Such capsules are crushed by the user before the cigarette is used and develop an additional taste when the cigarette is smoked.
  • additional elements or objects can also be introduced into the filter, such as activated carbon bodies, granules or the like.
  • the most common method of inserting additional elements in a filter rod is that the Additional elements are held on the circumference of an insert wheel in object seats acted upon by suction air and immerse with the circumference of the insert wheel in the course of the rotation of the insert wheel into the filter rod.
  • the suction air is switched off and the objects remain in the filter train.
  • the filter rod has a U-shape in cross-section at the transfer point so that the objects can be inserted into the filter rod safely and with little stress.
  • An object insertion device is for example from EP 2 502 510 A1 known.
  • the filter material strip in particular the tow strip, is conveyed through a transport nozzle with an excess of compressed air.
  • the transport nozzle also serves to gather the previously spread out filter material strip into a strand with a low density.
  • This still loose strand is then introduced into a tow guide, which is introduced from a guide tube with an internally arranged elongated mandrel or expanding mandrel, also called a plow.
  • the combination of the expanding mandrel and the guide tube arranged around it ensures that the loose filter rod in the guide tube wraps itself around the mandrel and the filter rod thus has the necessary U-shape into which the objects can subsequently be inserted from above.
  • EP 2 772 146 B1 also discloses a device for producing a filter rod in the tobacco processing industry, in which a guide channel is arranged at the exit of the transport nozzle, the cross section of which in the conveying direction of the filter rod is adapted on the inlet side to a cross section of the transport nozzle and on the outlet side is essentially rectangular.
  • a device for producing a filter rod of the tobacco processing industry from a filter material comprising a transport nozzle that can be acted upon by compressed air and a guide device which is arranged downstream of the transport nozzle in the conveying direction of the filter material, the filter material being guided through the transport nozzle and the guide device is guided, which is further developed in that the guide device comprises a guide tube which has an inlet and an outlet for the filter material, a filter material threading slot is provided which extends from the inlet to the outlet of the guide tube.
  • the guide tube preferably has a longitudinal axis, the filter material threading slot being aligned parallel or substantially parallel to the longitudinal axis. This enables the filter material to be threaded into the guide tube in a particularly simple manner.
  • a particularly low insertion tolerance of objects in the filter material i.e. a particularly high insertion accuracy, is possible if the guide tube either has a constant cross-sectional area or the cross-sectional area decreases in the conveying direction of the filter material.
  • the guide tube is in two parts, a second body part of the guide tube being stationary relative to an inlet finger of a format device arranged downstream of the guide tube.
  • a first body part of the guide tube is preferably provided, the vertical distance of which from the second body part can be varied. In particular, the height of the first body part in relation to the second body part can be changed. This makes it possible to adapt the cross-sectional area of the guide tube to the amount of filter material or the type of filter material, for example type of tow.
  • the inlet finger is preferably part of a format device in which a predefinable filter rod is formed from the filter material.
  • the infeed finger is part of an upper format of a format device.
  • the second body part of the guide tube is preferably releasably connectable to an upper part of the inlet finger, for example via screw connections.
  • the position of the first body part is preferably adjustable or adjustable together with the position of the outlet of the transport nozzle.
  • the height of the transport nozzle which also includes an air outlet funnel, which is arranged adjacent to the inlet of the guide tube, is varied in height
  • the corresponding height of the first body part can be adapted to this height.
  • an inlet edge of the first body part which is arranged at the bottom of the inlet of the guide tube, can be aligned with the outlet of the air outlet funnel of the transport nozzle in such a way that the filter material is safely guided over this inlet edge, in particular in contact with the inlet edge.
  • an opening depth of the filter material threading slot remains constant with a height adjustment of the first body part of the guide tube. This ensures that the depth of the slot remains the same, so that, on the one hand, it is ensured that filter material can always be threaded in consistently and, on the other hand, filter material from the tube cannot exit the filter material threading slot during operation.
  • the filter material is forcibly guided in the filter tube, preferably in the lower area, for example by appropriate arrangement of the guide tube relative to the format device and the air outlet funnel of the transport nozzle.
  • the guide tube preferably has at least one, in particular a lateral, air outlet opening in the first body part and / or second body part.
  • the air outlet opening provided there is to be understood in particular in addition to the filter material threading slot.
  • Air slots arranged longitudinally axially can preferably also be provided as air outlet openings.
  • an air outlet slot can be arranged on each side of the first body part and two air outlet slots in the lower region.
  • a different number of air outlet slots can also be provided, depending on the amount of air required Air to be discharged.
  • the width and length of the air outlet slots can also preferably be specified. At least one air outlet slot preferably has a constant width.
  • the guide tube preferably has an opening on the upper side for receiving a shaping element, the shaping element being designed to form a receiving groove for introducing objects into the filter material.
  • the forming element can be referred to as an expanding mandrel or tow expanding mandrel or a plow.
  • the shaping element expands the filter material in such a way that a receiving groove is formed for introducing objects into the filter material.
  • the guide tube preferably has a smooth surface at least in sections at the inlet, so that the resistance to the filter material is reduced when the filter material is transported along the guide tube.
  • a smooth surface is preferably a polished surface or a surface coated with a friction-reduced layer.
  • the guide tube preferably has a rounded inlet edge over which the filter material, in particular with contact, runs during transport.
  • the cross-sectional shape of the guide tube is preferably rectangular or square.
  • the edges are preferably rounded here.
  • Embodiments according to the invention can fulfill individual features or a combination of several features.
  • Fig. 1 shows schematically in a three-dimensional representation part of a device for producing a filter rod 10.
  • a filter material 41 which can be a filter tow, for example, is fed, after the usual preprocessing steps, to a transport nozzle 11 in which the filter tow material 41 is supplied with compressed air via a transport nozzle 11
  • Air outlet funnel 11a is guided to a guide tube 12 from which the filter material 41 is conveyed to a format device 23 in order to then be formed into a filter rod 40 in the format device 23, only a small part of which is shown.
  • a wrapping material is around the filter material 41 in FIG Formatting device 23 is wound and a round or elliptical filter rod 40 is produced, which can then be cut to length in filter rods of predeterminable length by a conventional knife device.
  • the format device 23 has a sub-format 18, of which only a part is shown in Fig. 1 is shown, and an inlet finger 17 which has a recess 33 for receiving an insert wheel, which is not shown.
  • the insert wheel is used to insert objects such as capsules filled with a liquid into the filter rod 40. So that this can be done safely and without damaging the objects or capsules to be inserted, the filter material 41 is preformed into a U-shape or V-shape by a shaping element 30, for example an expanding mandrel, so that there is space for inserting the objects into the filter material 41 .
  • the innovation according to the invention now provides for a filter material threading slot 16 to be provided in the guide tube 12, which is directly connected to the air outlet funnel 11a of the transport nozzle 11, in order to be able to introduce the filter material very quickly and safely and orderly when the device is started up, and to give others an air outlet possibility precisely at this point, so that the conveying of the filter material through the guide tube 12 takes place with low vibrations, for example in height. It has been found that by means of this measure according to the invention, the filter material pulsates significantly less, so that the objects can be placed more precisely in the filter rod 40.
  • the filter material threading slot 16 extends from an entrance 14 to the exit 15 of the guide tube 12.
  • the guide tube 12 is in the Fig. 2 and 3 shown again in more detail in three-dimensional representation from different perspectives.
  • the guide tube 12 comprises two body parts, namely a first body part 21 and a second body part 22.
  • the second body part 22 represents the top side 27 and part of a side surface of the guide tube 12 and comprises a holding device 35, which in this case has two slots for receiving screwing means, by means of which a fixed connection with, for example, the inlet finger 17 can be made, as in FIG Fig. 1 is shown.
  • two guide slots 34 are provided, which are designed in an elongated slot shape in order to enable a height adjustment of the first body part 21 relative to the second body part 22.
  • the filter material threading slot 16 is designed parallel or essentially parallel to a longitudinal axis 19 of the guide tube 12.
  • the filter material threading slot 16 is tapered in the upper region in the direction of insertion of the filter material by angled a side surface of the first body part 21.
  • air outlet openings 25 in the form of slots are provided in the guide tube 12 in order to be able to let out even more easily or even more air, so that when the filter material 41 is conveyed it pulsates even less.
  • the opening depth 24, i. the distance of the first body part 21 to the second body part 22 is constant or essentially constant in the, in particular the lower, area of the filter material threading slot 16 even when the height of the first body part 21 is adjusted relative to the second body part 22.
  • an opening 26 is provided in the second body part 22, which is used to receive the shaping element 30. In addition, this opening 26 can also serve to let air out of the guide tube 12.
  • an inlet edge 31 is provided, along which the filter material 41 runs. This inlet edge 31 is preferably rounded or chamfered.
  • the height of the transport nozzle 11 or the air outlet funnel 11a can be changed, as can the first body part 21 of the guide tube 12.
  • the height of the sub-format can also be changed 18 can be changed to allow the amount of filter material or an adjustment to the filter diameter or the type of tow.
  • an adjusting slide 32 is used to adjust the outlet cross section of the air outlet funnel 11a.
  • the invention makes it possible, in the production of a filter tow strand filled with objects, to more than halve the scrap that arises from an incorrect position of an inserted object.
  • the air slots are preferably so narrow that no filter material can escape.
  • only a few components are required for the implementation of the guide tube 12, which saves costs for the device.
