Definitions

  • the invention relates to a method for separating and inserting objects into at least one material rod of the tobacco-processing industry, in particular an endless filter rod.
  • the invention also relates to an apparatus for separating and inserting objects into at least one material rod of the tobacco-processing industry, in particular an endless filter rod.
  • the apparatus includes an object supply volume and a take-over device with discrete object receptacles for objects, such that a receiving section along the conveying path of the objects is arranged on the take-over device for receiving the objects in the object receptacles.
  • the take-over device is designed for inserting objects into the material rod or additionally includes an insertion apparatus for inserting objects into the material rod, which is arranged directly or indirectly in the conveying direction of the objects downstream from the take-over device.
  • the invention relates to a machine of the tobacco-processing industry, in particular rod maker, as well as a use.
  • the invention relates to the production of a material rod, in particular an endless tobacco rod or endless filter rod, for rod-like articles of the tobacco-processing industry, in particular for filter cigarettes.
  • the initially endless tobacco rod or endless filter rod is cut into individual tobacco rods or respectively filter rods after its production.
  • the endless filter rod or respectively the cut filter rods or tobacco rods contain as a major component one or more objects, which impact the smoke or filter properties.
  • the objects are in particular capsules with a solid cover, which are filled with a liquid.
  • the liquid normally contains flavor or scent additives, for example menthol.
  • a smoker breaks the capsule before smoking by pressing on the filter and then lights the cigarette. The liquid is released through the pressure on the capsule in the filter so that the aroma of the liquid unfolds. This procedure offers a particularly intensive or fresh taste sensation.
  • Corresponding capsules normally have a diameter of approx. 3 to 3.5 mm, but can also be smaller.
  • hard objects can also be used within the framework of the invention, also smaller or larger particles, for example balls or cylindrical objects made of active charcoal, extrudates or other filter materials or additives.
  • a generic technology comprises an insertion apparatus for capsules into a filter tow strip with a rotating insertion wheel.
  • the insertion wheel On its perimeter, the insertion wheel has receptacles for capsules, in which the capsules are held with suction air after insertion.
  • the perimeter of the insertion wheel penetrates continuously into the filter tow strip. In this instance, as soon as a capsule enters the filter tow strip, the suction air is switched off and the capsule is thereby placed in the filter tow strip so as to be further transported with the filter tow strip.
  • the filter tow strip mainly receives the shape of a “U”, so that the insertion wheel penetrates into the middle recess or respectively into the channel of the “U”. This is followed by the formation of an endless filter rod, in which the filter tow strip is closed, sealed and wrapped with a strip of plugwrap.
  • the conveyance of a filter tow strip and an endless filter rod formed from it in an endless filter rod machine takes place continuously.
  • the production speed and the conveying speed of the filter tow strip and of the endless filter rod formed from it are thereby restricted by the maximum speed of the insertion apparatus for objects to be placed in the endless filter rod.
  • This maximum speed is currently approx. 100 m/min.
  • the production speed is thus considerably lower than for conventional endless filter rods, into which no capsules are placed.
  • the filter rods populated with capsules must be ejected until the endless filter rod and the insertion wheel are synchronized.
  • the objects are received in the receptacles along the receiving section, are held in the receptacles of the insertion belt by suction air and conveyed to an insertion position on the material rod and are inserted into the material rod at the insertion position. In this manner, the speed differential between the objects and the object receptacles is reduced in the insertion belt so that the objects are received in a gentler manner than previously possible into the object receptacles.
  • embodiments of the present invention provide an alternative process and device for separating and inserting objects into a material rod of the tobacco-processing industry, with which a gentle and efficient separation of objects is possible.
  • a method for separating and inserting objects into at least one material rod of the tobacco-processing industry, in particular an endless filter rod.
  • objects are received from an object supply volume into an annular groove on the outer perimeter of an accelerator wheel rotating around an axis of rotation, and the groove is supplied with suction air.
  • the objects which are held by the suction air in the annular groove of the accelerator wheel, are accelerated in the course of the rotation of the accelerator wheel and are conveyed to a take-over device, which has discrete object receptacles for the objects.
  • Some of the objects in a receiving section along the conveying path of the objects are received in the object receptacles of the take-over device, are conveyed further in the object receptacles after leaving the receiving section and are then inserted into a material rod by the take-over device or an insertion device arranged downstream in the conveying direction of the objects.
  • the objects which were not received in an object receptacle of the take-over device in the receiving section are discharged after leaving the receiving section and/or are returned to the object supply volume.
  • a rotating accelerator wheel with an annular groove on the outer perimeter on which suction air is applied at least in sections has the advantage that the objects can enter directly from the object supply volume into the fitting circumferential annular groove, are movably held by suction air moving within the annular groove and are thus conveyed along with and accelerated in a gentle manner by the accelerator wheel.
  • rod production speeds are achievable for rods with inserted objects, which are comparable with those for material rods without inserted objects.
  • the annular groove is circumferential, there are no transverse edges in the annular groove, on which the objects can be damaged. Suction air is applied on the annular groove so that the objects in the annular groove can be suctioned and thus conveyed along by the rotating accelerator wheel. During rotation, the speed of the objects in the annular groove adapts to the circumferential speed of the accelerator wheel. In this manner, the entire section of the annular groove, which is located at one point in time in the object supply volume or in connection with the object supply volume, can be filled with objects.
  • the objects form a more or less closed object chain or object train, i.e. the objects are in touching contact with each other, wherein holes can also occur between objects due to the dynamic process.
  • These object chains are conveyed in a channel.
  • more objects are conveyed past the take-over device than can be received by the take-over device.
  • the excess objects, which were not received, are caught and/or returned to the object supply volume.
  • the objects are preferably accelerated on the accelerator wheel to a speed, which exceeds the conveying speed of the take-over device.
  • a minimum speed can also be set according to the invention as long as the speed differential is suitable in order to fill the object receptacles of the take-over device with objects.
  • the differential speed of the accelerator wheel, with respect to the conveying speed of the take-over device is preferably between ⁇ 30% and +30%, in particular preferably between ⁇ 15% and +15%.
  • an excess of objects is advantageously conveyed to the take-over device. This increases the probability that each object receptacle of the take-over device is filled with an object.
  • the excess objects are returned to the object supply volume by a second accelerator wheel with an annular groove to which suction air is supplied, which is arranged downstream of the take-over device.
  • a second accelerator wheel with an annular groove to which suction air is supplied which is arranged downstream of the take-over device.
  • the suction air is advantageously switched off along a portion of the perimeter in the direction of rotation, in particular between a transfer point to the take-over device and a point where the annular groove enters into the object supply volume. In this manner, suction air is saved and objects are prevented from being held back under the effect of the suction air on the accelerator wheel during transfer from the accelerator wheel to the take-over device.

  • a rotating or rotatable accelerator wheel is arranged between the object supply volume and the take-over device, which has an annular groove on which suction air is applied or appliable on its perimeter, the width of which is not or is only slightly greater than a diameter of the objects.
  • the apparatus according to the invention is also based on the gentle acceleration principle of the accelerator wheel with the annular groove to which suction air is applied.
  • the effect occurring in previously known systems i.e., that not every capsule finds a receiving chamber or respectively object receptacle in the insertion wheel or that objects are destroyed because they have not yet disappeared entirely in the object receptacle and are crushed on the wall of the object supply, which is caused by the fact that objects being conveyed with an undefined speed to an insertion wheel with discrete object receptacles have a large speed differential with the insertion wheel directly or indirectly in front of the receptacles, is avoided.
  • the restricted production speed of such systems is exceeded.
  • the objects are thus removed from an object supply volume by an accelerator wheel and are accelerated gently almost to rod speed.
  • the pre-accelerated objects are conveyed past a take-over device, which is equipped with suitable object receptacles.
  • the object chain already described above forms in the annular groove of the accelerator wheel.
  • the depth of the annular groove preferably matches a diameter of an object. The objects are thereby protected inside the annular groove on the accelerator wheel.

  • the suction air is for example insertable in the center of the accelerator wheel.
  • channels for the suction air which lead inward radially or with a tilt with respect to the radial, are arranged at least in one area adjacent to the annular groove, the pickup behavior of the objects is advantageously improved, among other things, in that a swirling of the suction air in the gap and differences in the suction and holding force caused by it in the circumferential direction are prevented.
  • a gap, via which all channels are supplied with vacuum or respectively vacuum pressure, can be connected to the channels on the inside.
  • the accelerator wheel has openings on one or both lateral surfaces, which are flush with a corresponding, fixed, in particular annular-section-shaped suction air nozzle and are connected with the annular groove inside the accelerator wheel.
  • the suction air is supplied from the side via openings, which are designed like a row of small openings or long-hole-shaped openings with the same or varying lengths.

  • the further-conveyed material rod with the inserted objects then has the reference number 2 .
  • the conveying direction of the material rod 1 , 2 is indicated with arrows.
  • Insertion belt 31 is conveyed via an upper return pulley 33 and a lower return pulley 34 , to rotate in the direction 31 a.
  • Lower return pulley 34 is simultaneously designed for inserting the objects from the object receptacles 32 of the insertion belt 31 into the material rod 1 . This process is described in greater detail in the Applicant's above-mentioned German Patent Application number DE 10 2011 017 615.2, which has been expressly incorporated by reference herein in its entirety.
  • FIG. 4 shows a second exemplary embodiment of a separating and inserting apparatus 40 according to the invention.
  • the upper part i.e., separation device 41
  • separation device 41 has an object supply volume 42 with an upper inlet 46 , a stripping wedge 44 and a recess 43 .
  • Object supply volume 42 is connected with a part of the perimeter of an accelerator wheel 10 with an annular groove 11 rotating in direction 19 .
  • Recess 43 has in this case an island-shaped blocked area 43 a, which defines a bent channel 43 b , whereby an object flow made up of excess objects is returned to the object supply volume 42 in a very orderly manner.
  • a part of the housing 45 forms an air control body 18 that switches off the suction air on annular groove 11 over a certain section of the perimeter of accelerator wheel 10 .
  • Transfer section 56 a extends approximately from stripping wedge 44 to a downstream take-over device 50 that is designed as an insertion wheel 51 .
  • the length of transfer section 56 a depends on geometric ratios in the apparatus and is designed in this exemplary embodiment over an area of approx. 170° of the perimeter of accelerator wheel 10 .
  • Stripping wedge 55 is arranged to ensure that, rather than remaining in annular groove 11 , the objects of the object chain in annular groove 11 are deflected into receiving section 56 designed as a channel located along a portion of the perimeter of insertion wheel 51 at a transition from transfer section 56 a to receiving section 56 .
  • receiving section 56 the objects of the object chain are conveyed with a differential speed around or past insertion wheel 51 , which has discrete object receptacles 52 on its perimeter and suction air applicable to each object receptacle 52 . Through this parallel conveyance with object excess and, if applicable, a differential speed, the probability that individual receptacles 52 remain unoccupied is minimized.
  • a stripping wedge 55 ′ strips off the non-received objects and deflects them into a discharge channel 57 , out of which they exit and are discharged, caught and returned, if applicable, to object supply volume 42 .
  • FIG. 5 shows schematically a third embodiment of a separating and inserting apparatus 60 according to the invention, which receives a separation device 61 according to the invention with an accelerator wheel 10 in the upper and left part, wherein in a housing 65 in turn an object supply volume 62 with a stripping wedge 64 , a recess 63 with island-like blocked area 63 a and bent channel 63 b is arranged, wherein objects in the annular groove 11 of the accelerator wheel are accelerated and transferred via a transfer section 76 a to a receiving section 76 on a take-over device, which is designed as an insertion wheel 71 .
  • the insertion wheel 71 with the discrete object receptacles 72 rotates in the direction of the arrow.
  • an object chain is transferred from annular groove 11 of accelerator wheel 10 into receiving section 76 designed as a channel and conveyed past object receptacles 72 of insertion wheel 71 such that objects received in object receptacles 72 are inserted into a material rod 1 in an insertion zone 78 .
  • a stripping wedge 75 is connected to the receiving section 76 on the insertion wheel 71 in FIG. 5 , which diverts the excess objects to a second accelerator wheel 10 ′′. These objects are received in annular groove 11 of second accelerator wheel 10 ′′ and are in turn accelerated in the direction of the arrow. Housing 65 thereby forms a return section 77 around second accelerator wheel 10 ′′, or respectively return section 77 is designed as a section of annular groove 11 of second accelerator wheel 10 ′′.
  • the objects in turn accelerated are received by a second stripping wedge 75 ′ out of annular groove 11 of second accelerator wheel 10 ′′ and conveyed back to the object supply volume 62 through a return channel 79 , where they can re-penetrate into annular groove 11 of first accelerator wheel 10 .
  • Return channel 79 is thereby protected from objects falling out of the upper inlet of object supply volume 62 by a protruding part of the housing wall so that an object jam does not form there. Instead, the objects coming from above on the bent wall with reference number 65 ′are diverted directly in the direction of first accelerator wheel 10 .
  • FIG. 6 shows schematically an accelerator wheel 10 , the circumferential annular groove 11 of which leads into channels 15 a progressing radially inward. These ensure that the suction air supplied to annular groove 11 makes its way evenly and without turbulence from outside through annular groove 11 towards the inside into accelerator wheel 10 , independently of where the objects in annular groove 11 are located. This once again improves the pickup behavior for the objects.
  • Channels 15 a which are arranged radially in FIG. 6 , can be arranged to be tilted with respect to or oriented at an angle to the radial.
