  • Such devices and methods are used in the tobacco processing industry to promote rod-shaped articles, such as filters or filter rods, axially and quickly over different distances in their longitudinal extent.
  • the articles are supplied from a supply or a magazine of the transmitter unit. Within the transmitter unit, the articles are supplied individually via a rotating drum into the region of a blow-off zone and from there conveyed or fired via a pneumatic pipeline to a receiver unit. For conveying the articles usually compressed air is used as conveying air.

  • the sealing block or the supporting block receiving the sealing block is designed as a supply plate for supplying conveying air into the hollows for the axial axial transfer of the articles into the delivery line.
  • the conveying air must on the one hand ensure that the articles have left the drum or the discharge channel in the direction of the subsequent pipeline in good time, that is to say in a predetermined time window, in order to prevent unwanted shearing off of the articles by the rotating drum.
  • the conveying air or the pressure must be sufficiently high in order to convey the articles completely through the pipeline to the receiver unit in order to avoid the articles remaining inside the pipeline.
  • a complex construction of the device is required. Furthermore, the load on the articles by their high acceleration in such a device is considerable.

Within the pressure chamber 20, the articles 14 are fed by means of the stripper roller 51 of the drum 12. By rotation of the drum 12, the articles 14 are supplied from the removal area or the receiving zone Z Auf within the pressure chamber 20 to the single-layer storage shaft 18.
  • the element 35 for combing out the articles 14 are released from the wells 13 and conveyed into the storage shaft 18. Within the storage shaft 18, the articles 14 are guided downwards in the direction of the discharge zone 16.
  • the holding member 30 guides the articles 14 and holds them at the same time to prevent the articles 14 from entering the purging zone 16 in disorder and uncontrolled manner.
  • the pressure within the pressure chamber 20 there is a pressure which is built up via the access 23, that is to say the so-called delivery line inlet pressure.
  • the pressure within the pressure chamber 20 corresponds to the transport pressure or shot pressure.
  • the pressure within the pressure chamber 20 can escape into the delivery line only via the outlet of the blow-off zone 16, so that a constant flow is built up within the blow-off zone 16 and the subsequent delivery line, which is responsible for transporting the articles 14 out of the blow-off zone 16 and through the delivery line is required.
  • the flow has a so-called working pressure, which is sufficient for firing and conveying the article 14 from the discharge zone 16 through the delivery line to the receiving station.
  • the flow rate through a nozzle at the air inlet, ie in the region of the access 23 can be increased.
  • the retaining strip 33 holds the articles 14 until a subsequent article 14 pushes the article 14 lying on the retaining strip 33 into the blowing zone 16.
  • the elasticity of the article 14 is used, which acts like a spring. Due to the continuous flow in the blow-off zone 16, the articles 14 are transported individually into the conveying line.
  • the respectively last or lowermost article 14 located in the stowage compartment 18, in combination with the delivery pressure formed by the advancing articles 14, is released by the holding element 30 and falls into the blow-off zone 16, from which the article 14 is controlled by the prevailing, entrained at working pressure flow and is conveyed from the discharge zone 16 in the delivery line.
  • Possible leakage within the pressure chamber 20 can be compensated by the additional access 24.
  • the sequential release of the article 14 in the blow-off zone 16, a gap formation between the articles 14 is possible.
  • the size of the gap can be varied, for example by increasing the trough distances in the drum 12.
  • the drum 12 can be automatically drained via the additional slot 37. If an automatic emptying or cleaning of the drum 12 is not possible, alternatively, a manual opening of the pressure chamber 20 may be possible.
  • the guide member 29 can also be moved downwards or downwards away from the drum 12, so that the accessibility to the area of the drum 12 and / or the storage shaft 18 is improved.
  • the pressure ratios within the device 10 may vary.
  • the compressed air with the supply pressure P V is first conducted via the supply line 68 into the nozzle body 66 and guided by the nozzle body 66 via the access 23 into the blow-off zone 16, so that in the region of the blow-off zone 16, the pressure P A prevails, which is lower than that Supply pressure P V is because the pressure P A via the delivery line 57 drops.
  • the area of the blow-off zone 16 is connected via the gap 67 between the drum 12 and the housing wall 64 of the transmitter unit 11 with the main chamber 21 in connection.
  • the nozzle body 66 which is connected to the drum 12, draws air from the inner space 56 of the drum 12 due to the air flow with the pressure P V and the nozzle (Venturi), so that the pressure P T within the drum 12 is less than the pressure P H in the main chamber 21, which is connected via the openings 55 with the interior 56 of the drum 12. Because the main chamber 21 is supplied with compressed air only via the blow-off zone 16, the pressure P H is lower than the pressure P A in the blow-off zone 16.
  • the embodiment of the arrangement 61 according to the FIG. 18 generates the pressure difference between the main chamber 21 and the interior 56 of the drum 12 in that both the main chamber 21 and the blow-off zone 16 are acted upon directly via the accesses 23 and 24 to the supply pressure P V and by a pressure differential between the supply line 68 and the blow-off zone 16 and on to the delivery line 57, a pressure gradient to the drum 12 is generated by a direct loading of the main chamber 21 with the supply pressure P V.
  • the ejector principle can additionally contribute to the formation of a pressure difference.
  • the air is discharged from the drum 12 or its interior 56 via the outlet line 60 (optionally with a check valve 69) and / or via the outlet line 60a (optionally with a pressure regulating valve with exhaust air opening, not shown).
