Definitions

  • the invention relates to a method according to the preamble of claim 1 and a device according to the preamble of claim 7.
  • the filters are usually transported from filter manufacture to further processing, for example in a filter attachment machine, via a pneumatic conveying line which is connected on the input side to a transmitting station and on the output side to a receiving station connected to the magazine of the further processing machine.
  • the filter rods are brought in a successive receptacle of a rotating transfer conveyor (transmitting drum) transversely axially from a supply into a firing position, in which they are aligned with the pneumatic conveying line.
  • a rotating transfer conveyor transmitting drum
  • the transfer conveyor continues to rotate, so that the filter rod in question is simultaneously moved transversely axially.
  • the launch zone in the direction of rotation of the transfer conveyor has an extension which is matched to the axial and transverse axial speeds of the filters during launch.
  • the mouth of the pneumatic delivery line is widened accordingly and runs towards the delivery pipe in a funnel shape.
  • a filter When operating properly, a filter has left its intake in the transfer conveyor when this intake is out moves out of the launch zone so that the transfer conveyor can move the next pick-up into the launch zone unhindered.
  • the invention has for its object to further improve a method and an apparatus of the type described above.
  • the aim is to prevent sheared parts of a filter from entering the further production process through the pneumatic delivery line and causing major disruptions there.
  • this object is achieved according to the invention in that the longitudinal axial movement of the filter from the receptacle into the delivery line is monitored during the movement of the receptacle through the firing zone and that an interference signal is generated if a filter within the receptacle concerned has not completely left a predetermined time interval.
  • the interference signal can be used for this purpose, the risk of shearing off due to the pinching of the filter and the associated risk Detect and remedy malfunctions at an early stage or initiate automatic troubleshooting.
  • the entry into the launch zone and its exit from the launch zone are recorded.
  • the time of entry specifies the start and the time of exit the end of the time interval in which a filter must have left its intake in the transfer conveyor when it was fired in order to ensure the error-free transport of the filter from the intake into the delivery line.
  • the transition of the front and rear filter ends from the receptacle into the delivery line are detected in succession and corresponding transition signals are formed, and an interference signal is formed if the times of both transition signals are not within the predetermined time interval for the launch.
  • the transverse axial movement of the conveyor is stopped automatically when an interference signal occurs.
  • This stop of the conveyor occurs before a filter that has not completely entered the delivery line can be sheared off by the rotating transmission drum.
  • the transmission drum is preferably turned back a little after stopping. The filter can then be easily removed from the transition area. This prevents filter fragments from entering the further production process through the delivery line.
  • Claims 5 and 6 contain measures for eliminating faults with which that filters caught during firing are quickly and safely removed from the conveyor.
  • the object on which the invention is based is achieved in that the receptacles in the launch zone are assigned monitoring means for monitoring the longitudinal axial movement of a filter from a receptacle in the delivery line and for generating monitoring signals which are dependent on the filter movement, and that the monitoring means are connected to an evaluation arrangement which emits an interference signal if the monitoring signals do not appear within a predetermined time interval.
  • Claims 8 and 9 contain preferred arrangements of the monitoring means with which the longitudinal axial movement of the filters from the receptacles into the delivery line is monitored.
  • the arrangement of the monitoring means in the sealing block is particularly advantageous because in this way it can be installed very precisely in the transition area between the rotating transmission drum and the mouth of the delivery line.
  • Claims 10 to 12 contain features of an embodiment of the device with which the movement of the individual receptacles through the firing zone is detected and the time interval available for the longitudinal axial movement of the filter rods during firing is predetermined.
  • Claims 13 to 16 relate to features of the device proposed according to the invention which enable the interference signals which occur to be used advantageously. This avoids the shearing off of insufficiently fired filter rods and it is achieved that in the transition between the transfer conveyor and the mouth of the delivery line stuck filters are automatically removed.
  • the main advantage of the invention is that disturbances occurring in the transmitting station are detected immediately and can be remedied automatically.
  • the return rotation of the transfer conveyor ensures that a filter that is jammed between the rotating transfer conveyor and the stationary mouth of the line is released and can be blown out with ease.
  • the fast fault detection and elimination ensures a high transfer rate of the pneumatic conveyor arrangement. This ensures that no sheared filter parts get into the delivery line and interfere with the operation of the subsequent machines. This is achieved with little technical effort.
  • the conveyor device shown in FIGS. 1 and 2 as an exemplary embodiment of the invention has a transfer conveyor in the form of a conveyor or transmission drum 1, which is provided with receiving troughs 2 for filter rods 3.
  • the receiving troughs 2, which are provided with suction bores 4 and delimited by webs 6, hereinafter also referred to as shots for short, run parallel to the axis of rotation 7 of the conveying drum 1 and are open radially outward.
  • the conveyor drum 1 can be driven continuously by a motor 8 via gears 9 and 11 by means of a shaft 12 in the direction of an arrow 13.
  • the upper side of the conveyor drum 1 borders on a filter rod magazine 14 with front and rear boundary walls 16 and 17, where the receptacles pass through a removal area 18.
  • the receptacles 2 take up filter rods oriented axially parallel one after the other from the magazine 14 and transport them transversely axially in the direction of arrow 13 into a firing zone Z arranged on the underside of the conveyor drum 1.
  • This firing zone Z is aligned axially axially with a mouth 22 of a pneumatic conveying line provided in a control ring 19 21.
  • the receptacles 2 of the conveyor drum 1 are closed radially outward to the surroundings with a sealing block 23.
  • the sealing block has a sealing surface 24 which is adapted to the arcuate path of the conveying drum 1 and extends along the circumference of the conveying drum 1 over the receptacles 2 adjacent to the firing zone Z.
  • the sealing block 23 is supported exclusively at its two ends with its sealing surface 24 sealingly on two stationary support bushes 19 and 26 arranged concentrically to the conveyor drum 1, the outer radius of which corresponds to the radius of the sealing surface 24, but is slightly larger than the outer radius of the conveyor drum 1.
  • the front support bush 19 is designed as a control ring in which a vacuum line 29 connected to a vacuum source 27 and leading at the end into a control slot 28 runs.
  • the control slot 28 corresponds to suction air bores 31 running axially parallel in the conveying drum 1 for the vacuum supply of the suction bores 4 in the receptacles 2.
  • the shaft 12 of the conveyor drum 1 is guided through the support bushings 19 and 26 and is mounted radially free of play outside of the support bushings in stationary housing walls 32 and 33.
  • the support bushes 19 and 26 themselves carry a stationary mounting plate 36 via traverse members 34.
  • the mounting plate receives two vertically arranged parallel guides 37 for the movement of the sealing block 23 and two compressed air cylinders 38 for two compressed air pistons 39 for the vertical up and down movement of the sealing block 23.
  • the sealing block 23 is formed in two parts in the embodiment shown. It consists of a sealing body 41 adapted to the outer shape of the conveying drum 1 and a supporting body 42.
  • the supporting body 42 is simultaneously designed as a supply plate in which a compressed air line 44 connected to a pressure source 43 runs.
  • a transverse bore 46 in the sealing body 41 and control slots 47 in a control flange 48 of the conveyor drum 1 are provided for introducing the compressed air from the compressed air line 44 into the receptacle 2 of the conveyor drum 1 located in the launch zone Z.
  • the conveyor drum 1 has a separate control slot 47 for each receptacle 2, which is connected to the latter via an axially parallel bore 49.
  • the compressed air thus comes from the pressure source 43 via a connecting line 51, through the compressed air line 44, the transverse bore 46 and the control slot 47, which is assigned to the receptacle 2 located in the launch zone Z, through the axially parallel bore 49 as shot or conveying air into the receptacle 2 aligned with the mouth 22 of the pneumatic conveying line.
  • a sensor 52 is arranged in the sealing body 41 of the sealing block 23, for example in the form of a reflection light barrier, which detects the movement of a filter rod 3 during firing into the delivery line 21. As shown in FIG. 5, this sensor 52 is connected to a control arrangement 53, which can be the machine control.
  • the conveyor drum 1 is assigned two position detectors 54 and 56, for example in the form of proximity initiators, which can also be integrated in the sealing block.
  • the position detectors 54 and 56 are also connected to the control arrangement 53 according to FIG.
  • FIG. 1 shows in the area of the inlet end of the conveying line 21 a compressed air connection 57 which is connected to the compressed air source and which is used for introducing blowback air into the conveying line.
  • Figure 1 shows the sealing block in its working position, in which its sealing surface 24 abuts the support bushings 19 and 26 and thereby seals the receptacles 2 of the conveyor drum 1 located in the firing zone Z to the outside.
  • the lower position, the maintenance position, of the sealing block 23 is indicated by a dashed line 58.
  • FIG. 5 shows, the conveying air connection 51, the compressed air connection 57 and the cleaning nozzle 59 are connected to the compressed air source via valves 61 to 63, so that the corresponding compressed air supply can be controlled.
  • electrical connection lines in the diagram of FIG. 5 are identified by a single line and pneumatic lines by double lines.
  • the free-ended arrows on the valves 61 to 63 represent the connections to the consumers 51, 57 and 59.
  • the sealing block 23 is raised from its lower maintenance position 58, for example for cleaning reasons, to its working position, in which its sealing surface, as shown in FIGS. 1 and 2, lies sealingly against the support bushings 19 and 26.
  • the compressed air cylinders 38 are actuated so that the pressure rams 39 move the sealing block 23 upwards against the support bushings.
  • the traverse members 34 absorb the pressure and bending forces exerted on the support bushings 19 and 26 and brace the system. Because of the smaller drum diameter of the conveyor drum 1, a defined free space remains between the peripheral surface of the conveyor drum 1 and the sealing block 23, so that the conveyor device can be operated without friction and therefore without wear.
  • the conveyor drum 1 which is driven by the shaft 12 at a constant speed, takes filter rods 3 from the magazine 14 into the receiving troughs 2 in the removal area 18, in which they are connected to the through the suction air bores 4, the axially parallel bores 31, the control slot 28, the vacuum line 29 from the vacuum source 27 applied suction air are held. If the axially parallel bores 31 of the conveying drum 1 emerge from the angular region of the control slot 28 during rotation in the conveying direction 13, the centrifugal force causes the filter rods to lie against the outer boundary of the receptacles 2 and to be moved along the latter. This outer boundary is formed above the sealing block by a cover plate 64 and in the area of the sealing block by its sealing surface 24. In the illustration in FIG.
  • filters 3 are only shown in the recordings, while the filters contained in the supply 14 have been omitted.
  • the filter rods 3 are transferred in the receptacles 2 by the conveyor drum 1 from the removal area 18 into the firing zone Z, in which the filter rods are aligned with the conveyor line. If the filter rod is aligned with the pneumatic delivery line 21 or with its stationary mouth 22, compressed air is supplied from the compressed air source 43 through lines 51 and 44 and through the transverse bore 46 and the relevant control slot 47 to the receptacle 2 aligned with the delivery line, which the filter rod 3 located therein is moved in the direction of an arrow 66 axially from the receptacle into the delivery line.
  • the filter rods are also moved transversely axially at the same time.
  • the mouth 22 of the delivery line 21 is widened in the direction of the transverse axial movement, which can be seen in FIGS. 2 to 4.
  • Figure 2 shows schematically a section approximately along the line BB of Figure 1.
  • Figures 3 and 4 show enlarged sections of the same cross-section in the region of the launch zone Z.
  • the section through the conveyor drum 1 has broken out at two points, so that there is a clear view of the end face of the support bushing or the control ring 19.
  • a part of the control slot 28 is visible in the upper part, which corresponds to the suction air bores 31 in the conveyor drum 1 for supplying the suction air.
  • the opening 67 of the pneumatic delivery line provided in the support bushing 19 can be seen.
  • Dashed in this figure indicates the receptacle 2 of the conveyor which is just aligned with this opening 67, in which a filter rod to be fired into the conveying line can be seen.
  • the right dashed line 68 represents the rear flank surface of the preceding web and the left dashed line 69 represents the front flank surface of the following web 6.
  • the firing of a filter rod 3 from a receptacle 2 of the conveyor can begin when the receptacle has reached the relative position shown in FIG. 3 relative to the opening 67 of the pneumatic conveying line.
  • the filter rod 3 is aligned with the mouth opening and can be moved freely from the receptacle 2 into the mouth opening 67.
  • the longitudinal axial mobility of a filter rod 3 ends when the receptacle 2 of the rotating conveyor relative to the mouth opening 67 has reached the position shown in FIG. 4, in which a filter rod, which has not yet completely left the receptacle, between the rotating conveying drum and the mouth of the stationary delivery line is pinched.
  • the two initiators 54 and 56 specify a time interval T (FIG. 6), in which a receptacle 2 is aligned with the opening 67 of the conveying line during the rotation of the conveying drum 1 such that a longitudinal axial movement of the filter rod into the conveying line is possible.
  • the initiators are set on the front flank surface 69 of the webs 6. When this flank surface 69 is detected by the initiator 54 at time t1, which is shown in FIG. 3, it forms a first position signal P1, which indicates that a receptacle 2 with the filter rod 3 conveyed therein is now aligned with the opening 67 of the delivery line and the launch can take place.
  • the transition from the Transversely axially moving receptacle 2 is assigned to the stationary mouthpiece 22 of the delivery line 21, the longitudinal axial movement of the filter 3 when fired. It generates a transition signal S indicating the beginning and the end of the filter passage through the detection range of the sensor, the temporal position and duration of which is checked by the control arrangement 53 relative to the time interval T.
  • a transition signal S indicating the beginning and the end of the filter passage through the detection range of the sensor, the temporal position and duration of which is checked by the control arrangement 53 relative to the time interval T.
  • the longitudinal axial filter movement from the receptacle past the sensor 52 into the delivery line which is indicated by the transition signal S, lies entirely in the time interval T; the filter leaves the receptacle completely while the receptacle passes through the launch zone Z.
  • Figures 6c and 6d show the signal curves in the event of a fault.
  • the control arrangement 53 emits an interference signal which immediately stops the drum drive 8 and brings the conveying drum 1 to a standstill before the filter clamped between the drum and the mouth of the conveying line is sheared off and filter fragments enter the conveying line. Immediately afterwards, the control arrangement 53 controls the motor 8, whereby the transmitting drum is turned back by a small angular amount and releases the clamped filter.
  • the filter If the filter is OK, it can now be moved into the delivery line 21 by the conveying air flowing further through the receptacle (FIG. 6c), as a result of which the fault is quickly remedied. If the filter cannot be conveyed any further (FIG. 6d), the control arrangement switches 53 the valves 61 and 62, thus switching off the conveying air and the blow-back air through the connection 57, so that the filter is moved back into the receptacle.
  • the sealing block 23 is moved into the lowered maintenance position 58 and its sealing surface 24 is blown out of the cleaning nozzle 59 by means of a compressed air stream, the blown-out filters being thrown into a collecting container, not shown.
  • the actuation of the sealing block drives 38 and the switching of the cleaning air valve 63 likewise take place as a function of the interference signal by the control arrangement 53.
