Definitions

  • the present invention relates to a conveyor device for rod-shaped smoking articles having the features of the preamble of claim 1.
  • Rod shaped smoking articles are e.g. Cigarettes, cigarillos, Heat Not Burn products (HNB products) or similar products intended for inhalation by a consumer. In this case, not only smoke, but instead or in addition, etheric or medicinal substances for inhalation may be provided despite the term.
  • rod-shaped smoking articles are also precursors of smoking articles to understand such. Filter rods, tobacco sticks with a by a strip strip shape-stabilized tobacco material, segments of HNB products, such as tubular cooling sections, taste-affecting segments or the like to see, which are subsequently connected to other precursors to a finished rod-shaped smoking article.
  • the rod-shaped smoking articles and precursors of the smoking articles are referred to hereinafter as "products" in the description for the sake of simplicity.
  • the products are transported in conveyors at a very high transport speed and produced and processed in very large quantities. They are supplied in different parts of the production process from a very large memory in a very large flow of individual products and for example via a drum assembly with several rotatory drivable drums, such as a removal drum, an accelerator drum, a staggering drum, a sliding drum and finally a delivery drum for transferring the products removed from the memory, wherein the order of said drums may vary.
  • the drums of the drum assembly are each cylindrical and have a plurality of arranged in the lateral surfaces, acted upon by vacuum, trough-shaped depressions, which are aligned with their longitudinal axes parallel to the axes of rotation of the drums.
  • the products are stored in the stack in a stack of parallel longitudinal axes, the products preferably being oriented so that their faces form mutually parallel planes, and the stack thus has a thickness equal to the length of the products in the reservoir equivalent.
  • a cutting device with directed onto the lateral surface of the removal drum and aligned parallel to the direction of rotation of the removal drum cutting blades may be provided on the removal drum, which cut the multiple-length products on the removal drum into simple products.
  • the troughs of the removal drum have to realize the cutting movement grooves, in which immerse the cutting blades and thereby cut the products over the entire cross-section.
  • the cut products of simple length are then staggered by the staggering drum and pushed back into a row on the sliding drum.
  • the products are taken from the memory in the wells of the removal drum and transported away transversely to their longitudinal axes.
  • the removal drum has to achieve a high transport capacity a comparatively large diameter with a plurality of in the lateral surface arranged troughs, which are arranged at a very small distance, ie in a very small pitch.
  • the removal drum is driven to achieve a reliable transfer of the products from the memory to a relatively low speed and a small peripheral speed of the wells.
  • the removal drum has particularly deep wells or wells with a one-sided enlarged wall, so that the products can be reliably removed from the memory first and secondly, so that an abutment for a clean cut of the products is formed by the cutter.
  • the supply of the products from the storage to the removal drum is effected by gravity, by the memory is arranged above the removal drum and having a removal drum facing opening through which the products emerge in the direction of the removal drum. Further, the feeding movement of the products to the picking drum is supported over the direction predetermined bands and rollers.
  • Such a conveyor is for example from the document WO 2014/188305 A1 known.
  • a problem of such conveyors is that the quality of the products exiting the conveyor and, in the case of precursors, also the quality of the finished end products made from the precursors, depending on the quality of the material supplied from the storage Products is. Furthermore, the quality of the products may also be adversely affected by damming of the products in the memory and by collisions of the products when they are run out of memory.
  • the invention has the object to provide a conveyor for rod-shaped smoking article, which should have an increased delivery capacity of the quality specifications corresponding products.
  • the inventive solution is based initially on the fact that between the memory and the drum assembly instead of the previous direct transfer now a guide channel is provided, in which the products are guided in a single-row strip.
  • the single-row guidance of the products in the guide channel in a single position creates the possibility of individually checking the products for compliance with predetermined nominal values of various parameters such as length, diameter, position, head condition, before they are fed to the drum assembly.
  • a sensor device is provided, which is specially designed, set up and arranged for checking the parameters to be maintained.
  • an ejection device is provided, which is actuated as a function of the signal of the sensor device.
  • the signal of the sensor device is in turn dependent on the undershooting or exceeding of predetermined limit values by the measured measured values of the parameters of the products to be detected.
  • the ejection device is activated or activated only when a product that does not correspond to the predetermined parameters, ie a product of inferior quality, is detected.
  • the drum assembly is then supplied with products having a lower error rate and improved averaged quality and, as a result, the averaged quality of the product produced end products improved at a non-reduced delivery capacity of the drum assembly.
  • the defective products are ejected before feeding to the drum assembly, so basically all troughs of the drum assembly are filled with defect-free products, and the conveying capacity is not reduced or the conveying capacity of the conveyor with products without defects in comparison is increased to the solution known in the prior art. Since the products automatically slip in the guide channel by gravity, the gaps created by ejecting the defective products in the guide channel are automatically closed again.
  • a very important feature of the invention is that the products are guided in a row in the guide channel and thereby can be detected individually, and the measurement results are not falsified by a multi-layeredness and a consequent superposition of the products in the measuring direction.
  • the probability of failure of the entire conveyor can be significantly reduced by the defective products are discharged in the transport direction upstream of the drum assembly, ie before entering the drum assembly.
  • the sensor device and the ejector are arranged so that they are passed during the transport movement of the products on the way from the memory to the drum assembly.
  • the term "between" is thus not limiting as a geometric arrangement to understand.
  • the ejection device can preferably be formed by a pneumatic blow-off device, which blows out the defective products from the strip of products in the guide channel.
  • a pneumatic blow-off device which blows out the defective products from the strip of products in the guide channel.
  • the ejection device may also be formed by a hollow drum, which has recordings which can be acted upon with underpressure or overpressure, the underpressure or overpressure in the receptacles preferably being controllable.
  • the products are first recorded in the recordings of the drum, the recording of the products can be supported in the recordings, for example, by an applied negative pressure in the recordings.
  • the products are then ejected by transporting the defective products from the transport chain of the products to an ejection point. This can be done, for example, by turning off the negative pressure in the receptacles in which non-defective products are kept at a first point and thereby delivering the non-defective products and forming the further transport chain to the drum assembly.
  • the recordings, in which defective products are kept, are subjected to negative pressure beyond the first point, so that the products are transported further to the ejection point.
  • the ejection of the defective products is then carried out in the ejection point either by switching off the negative pressure only passively and / or additionally by applying the recordings with overpressure, so that the products are actively ejected from the recordings.
  • This is the Control of the negative pressure or overpressure in the receptacles preferably designed such that the negative or positive pressure in the various shots is independently controllable, ie, the negative pressure or overpressure in a recording can be independent of the negative or positive pressure in the two be controlled adjacent recordings.
  • a rolling device which rotates the rod-shaped smoking article located in a detection region of the sensor device about its longitudinal axes.
  • the smoking articles which are currently in the detection range of the sensor device ie the smoking articles which are being detected by the sensor device, can be intentionally rotated about their longitudinal axes during the measurement, so that the parameters such as. e.g. the surface condition, roundness, seam course and the closure of the seam can be fully detected.
  • the created guide channel can be used in addition to the arrangement of a arranged between the ejector and the drum assembly cutting device for cutting the products.
  • depressions of normal depth can be provided for the first drum of the drum assembly and all other drums of the drum assembly, since no cutting process must be performed on any of these drums, so that the troughs provided on the drums do not have to form an abutment for realizing the cutting process ,
  • This can be a major, so far to be solved problem of the drum barrel, namely the transfer of products from deeper wells of the drum with the cutter in troughs of an acquiring drum are avoided with a normal depth.
  • drum run can be simplified because the cutting of the products takes place before the products enter the drum barrel, so that the speed jumps caused by the cutting in the drum assembly known from the prior art can also be avoided or reduced in number ,
  • a plurality of reservoirs are provided, each with a guide channel, from which the rod-shaped smoking articles are supplied to the drum assembly.
  • the proposed single-layer guide of the products in the guide channels has the advantage that the quality of the products can be detected prior to entry into the drum assembly, but the solution is disadvantageous in that the flow of products, which is supplied to the drum assembly due the limited feed rate of the products is limited in the guide channel.
  • This disadvantage can be compensated by providing a plurality of memories with associated guide channels from which the products are fed in a parallel guide of the drum assembly. Thereby, the flow rate of the products, which is supplied to the drum assembly, be multiplied according to the number of memories and the guide channels.
  • the delivery of the rod-shaped smoking article from the guide channels into the wells of the first drum of the drum assembly preferably takes place in a fixed predetermined rhythm, so that the memory emptied according to a predetermined feed characteristic and the wells of the first drum in a prior art distribution with the products of the various memory be filled.
  • the fixed predetermined rhythm preferably so be formed so that the products are supplied with identical flow rates from the various memories and taken in a uniform distribution in the wells of the first drum.
  • the supply of the products from the various stores can be further improved by a control device which controls the supply of the rod-shaped smoking articles from the various feed channels in the wells of the first drum.
  • the control means may e.g. be configured to control the delivery of the products from the various guide channels into the troughs in a coupling such that the products are successively inserted into the adjacent troughs of the first drum, the time offset being preferably adapted to the rotational movement of the first drum, whereby the delivery of the products from the various guide channels to the rotational movement of the first drum can be synchronized.
  • the wells of the first drum can preferably be subdivided into different groups assigned to the feed channels.
  • the proposed subdivision of the wells of the first drum, the wells can be subdivided according to the supply of the products from the memories, both in the geometric arrangement and in the adaptation of the ratios of the number of wells to the size ratios of the memory.
  • the number of wells of the different groups can be identical, provided that the flow rates of the products supplied from the stores are also identical.
  • the products of the various guide channels can be introduced by the proposed further development at the same time in the wells first drum become.
  • the wells of the various groups may preferably be arranged alternately successively.
  • the products are introduced through the various guide channels in different angular portions of the circumference of the first drum in the troughs, or in other words, the guide channels are passed by the troughs in succession.
  • the delivery of products from the guide channels in the adjacent troughs when circulating the first drum can be carried out successively, the point of delivery of the products from a guide channel always the filling position of the troughs corresponds to this assigned group.

  • the direction of rotation of the cutting blade 43 may be deliberately directed against the forced by the belt 41 relative rotational movement of the products 15, whereby the cutting speed can be further increased.
  • the length of the projecting into the guide channel 11 guide portion of the belt 41 and the relative speed of the guide portion are chosen so that the products 15 during passing of the cutting blade 43 at least once to rotate about its longitudinal axis that is driven to a full revolution relative to the cutting blades 43.
  • the products 15 are realized in a very high quality cutting process with a rolling against the cutting edges of the cutting blade 43 product 15, wherein the particular advantage of the cutting process in addition to the rolling process additionally consists in that the cutting edge always only to just over half of the cross section penetrates into the product 15.
  • the product 15 is loaded considerably less during the cutting process than in a section with a cutting across the entire cross-section cutting edge, as is the case with conventional cutting operations with not rotating about their longitudinal axis products 15.
  • the band 41 is designed so that it is arranged with the projecting into the guide channel 11 guide portion at a defined distance from the cutting edges of the cutting blade 43 so that the rotating products 15 are urged against the cutting edges and during the cutting process in the band 41 find an abutment.
  • the solution according to the invention also has the advantage that the products can escape due to the flexibility of the belt 41 and the cutting forces can be reduced thereby.
  • a cutting device 17 in which in addition to the, the cutting blades 43 opposite bands 41 in addition to the side of the cutting blade 43 further bands 44 are provided, which are aligned in the same manner, each with a guide portion parallel to the transport direction and with this Guide section protrude into the guide channel 11.
  • the products 15 are thus in the Section of the cutting device 17 laterally guided exclusively over the belts 41 and 44 and driven off to the rotational movement.
  • the bands 41 and 44 each comprise a plurality of individual, spaced strands and thus lie in strips on the products 15 at.
  • the products 15 are guided by the strip-shaped guide over a smaller surface and thus a total of a lower contact pressure.
  • the shorter products 15 of improved length are guided improved after cutting.
  • the two cutting blades 43 are thus arranged transversely to the transport direction of the products 15 in the longitudinal direction of the products 15 at a distance from each other, so that the products 15 are cut into three individual products 15 with a correspondingly shorter length.
  • the length of the cut products 15 can be defined by the distance between the cutting blades 43 to each other and the distance of the cutting blade 43 to the end faces of the supplied products 15 in the longitudinal direction of the products 15.
  • the cutting process, the resulting cut quality and finally dimensional accuracy of the cut products 15 can be further improved in terms of their length by a fine wobbling of the products 15 at their ends before the cutting process by which the products 15 within a to be observed during the cutting process target position within can be aligned to very tight tolerances.
