Definitions

  • the present invention relates to a conveyance apparatus for objects, in particular substantially cylindrical objects such as, for example filter elements or filter segments, for the use in smoking articles, and a method for conveying these objects.
  • conveyance apparatus for filter segments which comprise a first conveyance means in the form of a drum provided with axial flutes at the outer circumference of the drum.
  • a plurality of substantially cylindrical filter elements is provided in some of the flutes and rotates together with the drum along a first circumferential motion path with respect to the drum.
  • a driving chain is provided, which extends in the axial direction of the drum and engages at least one of the plurality of objects comprised in one flute of the drum.
  • the chain is adapted to convey the objects along a second motion path which is substantially axial in the direction of the drum, along the flutes to remove the objects from the drum.
  • this type of conveyance apparatus for filter elements comprises a stationary guiding means, which is enabled to guide the objects removed from the flutes of the drum while maintaining the orientation of their longitudinal axis which is in the conveyance direction of the guiding means.
  • the guiding means comprises an increased width at its end which is facing the drum.
  • the conveyance apparatus as known in the art has the problem that, due to the increased width of the guiding means, the objects which have just been removed from the flutes of the drum are not stably held in their preferred orientation and may, thus, rotate and be damaged or jam the section of increased width of the guiding means.
  • WO-A-2009/074540 discloses a rotating guiding element that moves with the same radial speed as the fluted drum.
  • the rotating guiding element comprises tapering grooves that guide the individual filter elements from the fluted drum into a stationary channel.
  • a conveyance apparatus comprising a first conveyance means with a plurality of holding means for objects.
  • the conveyance means is conveying the objects along a first motion path.
  • the apparatus further comprises a second conveyance means for removing the objects from the first conveyance means along a second motion path that is different from the first motion path.
  • the conveyance means is adapted to receive the objects along the second motion path while being adapted to follow the movement of the first conveyance means along the first motion path at least while receiving the objects transferred along the second motion path. According to the invention advantageously there is no need for a significantly widened section or flared entry portion as shown in the prior art.
  • the synchronization of the collecting means with the movement of the first conveyance means allows for an alignment of the conveyance means even in motion.
  • at least the end of the collection means, which is facing the first conveyance means is at a suitable position for receiving the objects which are moving along the second motion path.
  • the objects are in particular filter elements or filter segments for smoking articles.
  • filter segment is used throughout the specification to refer to a segment of a filter that may form a part of or be the entire filter for a smoking article.
  • the filter segment may also comprise the filter elements of more than one filter, that is, a rod of multiple filter elements that is severed into smaller filter segments at a later production of smoking articles. Typically, such a filter rod has the length of two or four filters of the final smoking article.
  • filter segments are, without limitation, plain filter tow plugs or filter tow plugs with additional elements like, for example, beads, capsules, plant material or threads disposed in the filter material.
  • Further examples for filter segments are non-cuttable objects like, for example, restrictor elements or tubular elements.
  • filter segments are plugs comprising other non-tow material, like for example, plant material, beads, capsules or granules or combinations thereof.
  • the segments may also be combinations of two to five individual filter elements, like for example a double filter segment comprising a plain filter tow segment and a filter tow segment with carbon beads.
  • the segments may also be combination of filter segments as above with "void" elements, that is, segments that are empty, like for example a so called plug-space-plug filter or a filter with a mouth-end cavity.
  • filter is used to refer to the location of the filter segment in the filter portion of the smoking article without making a reference of the possible filtration effect of such a filter segment.
  • the collecting means is adapted to move in the direction substantially opposite to the first motion path of the first conveyance means after having received the objects from at least one holding means of the first conveyance means.
  • objects can be received from the next downstream holding means on the first conveyance means.
  • This reciprocating motion of the collecting means enables that objects from subsequent holding means on the first conveyance means can be received in the collecting means while the first conveyance means is constantly moving.
  • the movement velocity of the collecting means in the direction substantially opposite to the first motion path is higher than the movement velocity of the collecting means during following the movement of the first conveyance means along the first motion path.
  • it is at least two times higher, preferably at least five times higher. This has the benefit that the time in which the objects can be transferred from the first conveyance means to the collecting means is increased, while the time the collecting means is moved in the opposite direction of the first motion path is lowered, such that the throughput of objects in the conveyance apparatus can be increased.
  • the first conveyance means is a drum rotating around its central axis, and the first motion path is the circumferential direction on the circumference of the drum.
  • the first motion path is defined as a circle whose diameter substantially corresponds to the diameter of the drum.
  • the direction of movement on the first motion path is defined by the rotation direction of the drum.
  • Drums are common conveyance means for components of smoking articles.
  • the objects are provided in a substantially radial direction to the drum, for example from a hopper. The objects are then rotated together with the drum until they are removed by the second conveyance means.
  • the preferred holding means are flutes in the outer circumference of the drum, which extend along the second motion path, which is preferably substantially in the axial direction of the drum.
  • the flutes are linear recesses in the axial direction at the outer circumferential surface of the drum.
  • the recesses forming the flutes have a semi-circular cross section to facilitate the accommodation of cylindrical objects.
  • the objects are held in the flutes by the application of a vacuum.
  • suction holes provided with a lower pressure than ambient pressure are arranged in the flutes to enable to hold the objects in the flutes.
  • the suction holes are preferably connected by means of suction lines in the drum to a vacuum source, which is provided separate from the drum.
  • the collecting means is a channel bordering on the first conveyance means, having a slightly funnel-shaped receiving end portion.
  • the slightly funnel-shaped receiving end portion is arranged next to the first conveyance means and is adapted to receive objects moving along the second motion path while following the movement of the first conveyance means along the first motion path.
  • the funnel-shaped receiving portion is only slightly widened, as it only has to enable a smooth transition of the objects from the first conveyance means to the collecting means and not to correct any misalignment in between the collecting means and the first conveyance means as known in the prior art.
  • the width of the funnel-shaped receiving end portion is smaller than the length of the objects. This prevents that the objects can turn other than around their longitudinal axis.
  • the alignment in between the collecting means and the first conveyance means is obtained by the synchronous movement of at least a portion of the collecting means with the first conveyance means along the first motion path.
  • the funnel-shaped receiving end portion of the collecting means is arranged directly at the end portion of one of the flutes and moves together with the flutes which are arranged on the rotating drum.
  • the end portion of the flute is at the outer circumference of an axial end portion of the drum.
  • the channel has a cross-section adapted to the geometry of the objects for substantially maintaining the orientation of a longitudinal axis of the objects in the channel direction.
  • the objects have a length along the longitudinal axis which is greater than the width or the height of the objects.
  • the objects are cylindrical objects, wherein the longitudinal axis extends centrally and in parallel to the nappe of the cylindrical objects.
  • the channel preferably has a circular or semi-circular cross-section which is slightly larger than the diameter of the cylindrical objects but substantially smaller than the length of the objects in the longitudinal direction.
  • the orientation of the longitudinal axis is substantially maintained throughout the channel, while the cylindrical objects are not restricted from rotating around their longitudinal axis.
  • the longitudinal axis of the objects is in alignment with the second motion path.
  • the collecting means is mounted by means of a hinge at a distance to the receiving end portion, so that the receiving end portion is enabled to follow the movement of the first conveyance means along the first motion path by means of rotating around the hinge.
  • the rotational axis of the hinge is substantially perpendicular to the rotational axis of the drum. This is a further reason to have a slightly larger funnel in order to compensate for the change of angle between the flute and the channel of the collecting means.
  • the rotation velocity of the collecting means is determined by the rotation velocity of the drum multiplied by the radius of the drum and divided by the distance in between the hinge and the drum.
  • the collecting means which is substantially directed towards the drum, moves with its receiving end portion at substantially the same speed as the corresponding flute of the drum.
  • a reciprocating rotation of the collecting means is carried out during which the collecting means remains substantially directed towards the drum.
  • the object would start to enter the funnel of the collecting means towards the right side of the funnel, but would finish the transition between holding means and collecting means towards the left side of the funnel.
  • each holding means on the first conveyance means holds a plurality of aligned objects.
  • the collecting means is adapted to follow the movement of the first conveyance means while the second conveyance means transfers the plurality of aligned objects from one holding means to the collecting means.
  • 2 to 10 objects are provided in each holding means in the first conveyance means, more preferably, 2 to 6 objects. As several objects can be transferred at the same time from one holding means to the collecting means, a high throughput of the apparatus can be obtained.
  • the second conveyance means is a belt or a chain with driving protrusions, which are adapted to engage with the objects in the holding means of the first conveyance means and to convey the objects into the collecting means.
  • the driving protrusions move along the holding means and engage the objects.
  • the driving protrusions are fingers provided on the belt or chain.
  • the holding means are flutes on a fluted drum.
  • the protrusions will only engage the most upstream objects in the holding means while all downstream objects will be pushed by the adjacent upstream objects.
  • the protrusions are arranged with a certain flexibility along the first motion path, so that they remain in the holding means despite the holding means being moved further along the first motion path.
  • the holding means are adapted to guide the objects arranged therein, while the objects are driven by the belt or chain.
  • the belt or chain has only to provide a driving force, while the alignment and guiding will be provided by the holding means.
  • Common driving protrusions known in the art may be provided to engage the objects.
  • Such common driving protrusion may be provided on the belt or chain so that they maintain their orientation with respect to the belt or chain and are, thus, changing their orientation whenever the belt or chain changes its orientation.
  • the driving protrusions will typically perform a change of orientation in the circumferential direction of a guiding wheel, like for example a sprocket.
  • this will lead to a velocity increase of the tip of the protrusion and thus to an increased driving velocity regarding the objects which causes an unsteady conveyance velocity of the objects.
  • the changing of the orientation of the driving protrusion may pinch and damage the object during the change of orientation.
  • the driving protrusions in particular, fingers are arranged on the belt or chain, such that they maintain their absolute orientation throughout the movement of the belt or chain. That means while the belt or chain section to which the driving protrusion is fixed rotates around the pulleys or sprockets, the driving protrusion remains in the same orientation. In particular, this is enabled by a mechanical transmission in between the belt or chain and the driving protrusions, which compensates the rotation of the belt or chain. By means of the mechanical transmission in between the protrusions and the belt or chain, the protrusions remain in one orientation. Preferably, the orientation of the driving protrusions remains substantially vertical throughout the entire motion of the driving protrusions.
  • the protrusions will only slightly reduce their driving velocity when the belt or chain is guided around a pulley or chain sprocket, while being retracted from the objects. This allows for a smooth, continuous movement of the objects.
  • two driving protrusions are provided on the belt or chain.
  • At least one air nozzle is provided in the collecting means to supply pressurized air for conveying the objects.
  • the air nozzle forms a beneficial driving means for the objects in the collecting means, as it enables that no additional mechanical parts have to be provided in the collecting means to drive the objects.
  • This is particularly beneficial, as the collecting means has in some embodiments, the form of a channel, and thus does not allow a proper engagement of outside driving means with the objects.
  • the air nozzles allows to design a lightweight collecting means, which is beneficial regarding reciprocating movements at high speed of the collecting means.
  • the collecting means may comprise a slot for allowing a driving means, such as the aforementioned protrusions, to engage with the objects.
  • the collecting means comprises a downstream end portion which is arranged adjacent to an upstream set of rollers next to which a downstream set of rollers is arranged.
  • Each set of rollers engages the objects from at least two sides, wherein the upstream set of rollers rotates at a velocity lower than the downstream set of rollers, so that objects which were previously adjacent to each other are separated from each other.
  • a set of objects in contact with each other upstream of the rollers will have a defined distance in between the objects downstream of the rollers.
  • the distance in between the upstream set of rollers and the downstream set of rollers is adjustable, enabling objects of different lengths to be processed. As the velocity of the sets of rollers is different, the distance has to be adjusted so that the length of the object is not greater than the distance in between the engaging portions of the two sets of rollers. Such, objects are advantageously not engaged at the same time by both the upstream and downstream set of rollers.
  • a conveyance disk is provided downstream of the sets of rollers, the conveyance disk having teeth which engage each of the objects separated by the sets of rollers individually to arrange them at defined locations of a further downstream conveyance line.
  • the distance between the objects created by the rollers is adapted to allow the conveyance disk to enter the teeth between the objects.
  • the object of the invention is further solved by a method for conveying objects, in particular, filter elements for smoking articles, which comprises the following steps.
  • the objects are conveyed in a plurality of holding means on a first conveyance means along a first motion path. Then, all objects are removed from one of the holding means along a second motion path which is different from the first motion path. Subsequently, the objects are collected by a collecting means which follows the movement of the first conveyance means along the first motion path at least while receiving the objects along the second motion path.
  • the collecting means carries out a reciprocating movement substantially along, and substantially opposite to, the first motion path.
  • the movement in the substantially opposite direction of the first motion path constitutes a returning motion.
  • the collecting means can be maintained in alignment with one of the holding means while the objects are transferred from the holding means to the collecting means, and then be brought into alignment with the next or another of the holding means.
  • the movement velocity of the collecting means during the step of returning is higher than during the step of collecting the objects.
  • the objects are in contact with the next upstream and downstream objects in the collecting means and a defined distance is established in between each of the objects downstream of the collecting means.
  • the defined distance allows that the objects can be individually selected and conveyed by further processing means during the manufacture of smoking articles.
  • the method may further comprise all features specified as inherent functional features of the conveyance apparatus according to the various embodiments of the invention.
  • a conveyance apparatus 1 for objects 2, in particular filter elements for smoking articles, is depicted.
  • Filter elements are substantially cylindrical objects. Typically, such filter elements have a greater length than diameter.
  • filter elements may comprise a constriction in their nappe, which is a section of lower diameter.
  • a longitudinal axis is defined to extend centrally in the objects in parallel to their nappe in the direction of the length of the objects and perpendicular to their diameter.
  • the objects 2 may in particular be restrictors for smoking articles, which are combined with filter material to form a filter segment of a smoking article. These types of restrictors are preferably formed from plastic material.
  • the objects 2 are initially provided to a drum 3, which is depicted in cross section in Figure 1 and which is adapted to rotate around its central axis 100.
  • the drum 3 is a generally cylindrical body, which comprises flutes 4.
  • the flutes 4 are axially extending recesses in the outer circumferential surface of the drum 3.
  • the flutes are formed such that they can accommodate and hold the objects 2 therein.
  • the cross section of the flute may at least partially have a shape which corresponds to the outer shape of the objects, however being slightly larger, such that the objects can still move in the axial direction of the drum 3.
  • the objects 2 are conveyed on the outside of the drum 3 along a first motion path, which corresponds to a circular motion path along the circumference of the drum 3.
  • a first motion path which corresponds to a circular motion path along the circumference of the drum 3.
  • the objects 2 are maintained in a generally fixed position in the flutes 4 of the drum 3, such that they cannot fall out in the radial direction.
  • This may be obtained by the form of the flutes 4, or by further holding means, such as clips or suction holes which apply a lower pressure to the objects 2 to maintain them in the flutes 4.
  • the holding means may be a guide plate that is distanced sufficiently from the drum so as to allow for movement of the objects but prevents the objects from falling out of the flutes during the rotational movement of the drum.
  • the drum 3 constitutes the first conveyance means in this embodiment of the invention.
  • the first conveyance means may have an additional cutting feature for separating the objects from each other. This may be implemented by providing knifes next to or in the drum.
  • the knives may be stationary such that the rotation of the drum allows for the cutting of the objects.
  • the knives may alternatively be rotating with the drum.
  • an actuator such as a servo or linear drive, or a cam drive, may provide the cutting motion of the knives.
  • filter material provided to the drum as a longitudinally extending rod may be cut into individual objects.
  • the second conveyance means is a chain drive 5, which comprises a first sprocket 6 and a second sprocket 7 and a chain 8 provided in between the two sprockets 6, 7.
  • the extension of the chain 8 is generally aligned with the flute 4 in the lowermost position of the drum 3.
  • the chain drive 5 generally extends in the axial direction of the drum 3.
  • the chain 8 is provided with two protrusions in the form of fingers 9.
  • the fingers 9 are provided at opposite positions of the chain 8, such that the distance in between the fingers 9 is the same along both directions of the chain 8.
  • the fingers 9 are connected by means of a mechanical transmission to the chain 8, such that the fingers 9 maintain in the orientation even when the corresponding chain links are moving along the first or second sprockets 6, 7 and are thus rotated.
  • the fingers 9 are adapted to project into the lowermost flute 4 of the drum 3 and move in the axial direction of the drum 3 throughout the flute 4.
  • the finger 9 engages the rightmost and therefore most upstream object 2 in the flute 4.
  • the most upstream object 2 will then come into contact with the next downstream object 2, and so forth until all objects 2 comprised in the flute 4 are transported together in the axial direction of the drum 3.
  • the axial direction of the drum 3 constitutes the second motion path.
  • the fingers 9 are adapted to maintain their absolute orientation throughout their movement with the chain 8. This is illustrated by the finger 9 in dashed lines in Fig. 1 , which is rotating with respect to the chain link on which it is primarily fixed, when the chain link travels along the sprockets 6,7. Thus, the finger 9 maintains its absolute orientation. This provides the benefit that no further acceleration of the tip of the finger 9 is effected by the rotation of the finger 9 which could otherwise lead to an unsteady conveyance speed of the objects 2 driven by the finger 9 or to the damaging of the filter elements
  • the collecting means 10 is a channel, which is slightly widened towards its receiving end 11, which is adjacent to the drum 3.
  • the receiving end 11 is provided close to the drum 3, such that the receiving end 11 and the opening of the flute 4 are substantially aligned.

  • the collecting means only carries out a reciprocating rotating movement around the upright axis 200. This is sufficient, as the objects 2 are transferred at high speed in little time from the flute 4 to the collecting means 10. Thus the first motion path is almost linear during the transfer.
  • the vertical components of the circular first motion path can be compensated by a slightly widened receiving end portion 11 of the collecting means 10.
