Definitions

  • the invention relates to a method according to the preamble of claim 1 and an apparatus according to the preamble of claim 7.
  • the transport of the filters from filter production to further processing, for example in A filter attachment machine is usually carried out via a pneumatic delivery line on the input side to a transmitting station and on the output side to one with the magazine of the Processing machine connected receiving station is connected.
  • the filter rods are rotating in successive shots Transfer conveyor (transmission drum) transaxially from a supply to a launch position brought, in which they are aligned with the pneumatic conveyor line.
  • Transfer conveyor transmission drum
  • the transfer conveyor continues to rotate, so that the filter rod in question at the same time is moved axially.
  • the launch zone has an extension in the direction of rotation of the transfer conveyor, on the axial and cross-axial speed of the filters at launch is coordinated.
  • the mouth of the pneumatic delivery line has been expanded accordingly and runs funnel-shaped towards the conveyor pipe (GB 2 068 325 A).
  • This GB 2 068 325 A describes a pneumatic conveyor system that uses five filter manufacturing machines pneumatic conveyor lines with five magazine groups of filter processing machines connects.
  • the conveyor lines connect two transmission stations in pairs above described type with a magazine of a processing machine.
  • This system has one Series of sensors for detecting fault conditions and for generating fault signals on. This controls whether the sealing shoe or sealing block is opened, whether the Coupling disengages due to overload, whether the stock in the magazine is replenished, whether rods in enter the delivery line or whether there is a backlog in the delivery line.
  • the invention has for its object a method and a device of the beginning to further improve the described type.
  • the aim is to prevent sheared off Parts of a filter through the pneumatic conveyor line in the further production process get there and cause major interference.
  • this object is achieved according to the invention solved in that the movement of the recording through the launch zone longitudinal axial movement of the filter from the intake into the delivery line is monitored and that an interference signal is generated if a filter within the recording in question has not completely left a predetermined time interval. When an interference signal occurs immediately the transverse axial movement of the conveyor stopped.
  • the entry of a Admission to the launch zone and exit from the launch zone detected.
  • the time of entry gives the start and the time of exit before the end of the time interval, in which a filter on launching its inclusion in the transfer conveyor must have left the error-free Transport the filter from the intake to the delivery line guarantee.
  • the Method according to the invention when firing a filter successively the transition of the front and the rear End of filter from the intake in the delivery line and corresponding transition signals are formed, and there is an interference signal formed if not the times of both transition signals within the time interval specified for the launch lie.
  • Claims 7 and 8 contain preferred arrangements of the monitoring means by which the longitudinal axial movement the filter from the recordings in the delivery line is monitored becomes.
  • the arrangement of the monitoring means in the sealing block is particularly beneficial because it is very accurate in this way in the transition area between the rotating transmission drum and the mouth of the delivery line can be installed.
  • the Claims 9 to 11 contain features of an embodiment of the Device with which the movement of the individual recordings through the launch zone and that for the axial movement the time interval available for the filter rods during firing is specified.
  • Claims 12 to 15 relate to Features of the device proposed according to the invention, the enable advantageous use of the interference signals that occur. This makes shearing insufficiently shot Filter rods avoided and it is achieved that in the transition between the transfer conveyor and the mouth of the conveyor line stuck filters are automatically removed.
  • the main advantage of the invention is that in disturbances occurring at the transmitting station can be detected immediately and they can be remedied automatically. It is through the return rotation of the transfer conveyor when it occurs Disorder ensured that a rotating between the Transfer conveyor and the stationary mouth of the line jammed filter is released and easily blown out can be. The quick detection and elimination of faults ensures a high transfer rate of the pneumatic Funding arrangement. This ensures that none are sheared off Filter parts get into the delivery line and the operation of the following machines. That will be with little technical effort achieved.
