Definitions

  • this known solution provides a continuous and uncontrolled rotation of the drum, and the selective delivery of a stream of compressed air to the specific transfer unit for which it is required to feed the filter.
  • a pneumatic device is installed to transfer the filtering segments.
  • the feed unit comprises a rotating drum provided with housing seatings for the filters and selectively rotatable around an axis of rotation to take at least part of the rotating drum, that is provided with housing seatings, into a removal zone and into a transfer zone.
  • the feed unit comprises a plurality of delivery nozzles and transfer pipes disposed in the transfer zone upstream and respectively downstream of the rotating drum.
  • Each of the delivery nozzles is configured to deliver, selectively and independently from the other delivery nozzles, a jet of air under pressure into one of the housing seatings, and each of the transfer pipes is configured to receive the filters from one of the housing seatings and to transfer them, along their longitudinal development, toward the user machine.
  • the controller allows to determine a precise positioning of the rotating drum with respect to the delivery nozzles and the transfer pipes, in order to selectively take the housing seatings that contain the filters into a position suitable for the subsequent transfer through the transfer pipes.
  • this solution allows to position the feed unit and the user machine separate and distanced from each other in order to adapt to specific positioning needs of the latter. Furthermore, the distanced positioning of the feed unit and the user machine allows to define operating spaces in which the operators can move, for example, in order to carry out maintenance operations.
  • transfer pipes to connect the feed unit to the user machine also allows to simplify possible maintenance or operations to remove possible blockages. For example it can be provided to quickly replace the feed unit simply by disconnecting the transfer pipes from the user machine and connecting another feed unit to it.
  • Embodiments of the present invention concern a feed unit of filters F indicated in its entirety by the reference number 10.
  • the removal device 12 is mobile between a removal zone 16 associated with, in this specific case positioned in, the container 11 and in which the filters F are removed from the latter, and a transfer zone 17 from which the filters F are transferred toward the user machine 101, as described hereafter.
  • the rotating drum 14a is selectively rotatable around an axis of rotation Z in order to take at least one of its parts, provided with the housing seatings 15, into a removal zone 16, located in the container 11, in order to remove and insert the filters F in the housing seatings 15, and into a transfer zone 17.
  • the transfer zone 17 can be positioned externally to the container 11 to facilitate the subsequent transfer operations of the filters F toward the user machine 101.
  • the removal device 12 comprises a transfer body 14 provided with said housing seatings 15, and a movement member 20 configured to move the transfer body 14 from the removal zone 16 to the transfer zone 17.
  • the housing seatings 15 have cross section sizes bigger than or equal to those of the cross section of the filter F.
  • the portion of the rotating drum 14a that is positioned in or facing toward the container 11 defines the removal zone 16 of the filters F from the container 11, while the portion of the rotating drum 14a located externally to the container 11 defines the transfer zone 17 of the filters F toward the user machine 101, as described hereafter.
  • the rotation of the transfer body 14, or the rotating drum 14a can be controlled by a controller 38 configured to determine and/or control the angular displacement of the rotating drum 14a.
  • the controller 38 allows to manage the functioning of the removal device 12 and the modality/cadence of feed of the filters F, as described hereafter.
  • a pneumatic ejection device 23 can be associated with the removal device and is configured to deliver a plurality of jets of air under pressure into the removal device 12 and pneumatically expel the filters F from the latter.
  • the pneumatic ejection device 23 comprises a plurality of delivery nozzles 24, each of which is provided to deliver, independently from the other delivery nozzles 24, a respective jet of air under pressure and define the expulsion of a respective filter F.
  • each delivery nozzle 24 can be positioned in correspondence with a first end 25 of one of the housing seatings 15, when it is located in the transfer zone 17, to deliver a jet of air under pressure into the latter and determine the expulsion of one filter F through a second end 26 of the respective housing seating 15, as identified by the arrow A in fig. 1 .
  • the housing seatings 15 extend for the entire length of the transfer body 14, or the rotating drum 14a, and therefore their first ends 25 and second ends 26 are made open toward the outside also in a direction parallel to the axis of rotation Z of the rotating drum 14a, in correspondence with the lateral ends of the latter.
  • the delivery nozzles 24 are installed in the transfer zone 17 according to a pattern coordinated to the positioning pattern of at least some of the housing seatings 15 of the removal device 12.
  • the selector members 29 can comprise at least one of either an interception valve, a flow regulation valve, a pressure regulation valve.
  • the selector members 29 can be connected to a management and control unit 30 configured to selectively drive the delivery of compressed air through the respective delivery nozzle 24 and therefore regulate the transfer action of the filters F.
  • each jet of pressurized air delivered by the delivery nozzles 24 is delivered not only through the removal device 12 but also through a respective transfer pipe 31, thus generating the transfer of the filters to the user machine 101.
  • the controller 38 can comprise a detection device 39 configured to detect the angular position of the rotating drum 14a.
  • the controller 38 also defines the stable, and at least instantaneous, angular positioning of the rotating drum 14a to allow the subsequent transfer of the filters F through the transfer pipes 31.
  • the rotating drum 14a can be kept in a fixed position at least for the discharge time of the filter from the respective housing seating 15, and that the rotating drum 14a is subsequently moved step-wise to take another group of housing seatings 15 containing the filters F into the transfer zone 17.
  • the detection device 39 can comprise, for example, an encoder able to detect the amplitude of angular rotation that is imparted to the rotating drum 14a when driven, and to position the group of housing seatings 15 in an at least temporarily fixed position, in order to discharge the filters.
  • the encoder can also allow to detect the angular position taken by each housing seating 15 during rotation of the rotating drum 14a.
  • the orientation of the terminal end 33 allows to meet particular feed conditions of the user machine 101.
  • the transfer pipes 31 can develop according to a straight path, and curved to reach the user machine 101.
  • the terminal ends 33 can be provided with releasable attachment/detachment elements 37, such as connectors, configured to allow quick connection/disconnection of the transfer pipes 31 to/from the user machine 101.
  • the releasable attachment/detachment elements 37 allow, for example, to quickly remove possible blocking conditions, or to quickly replace the feed unit 10 associated with the user machine 101.
  • columns of filters F are generated in the transfer pipes 31, aligned to each other along the longitudinal development of the transfer pipes 31 and that, on each occasion, the filter F discharged from the removal device 12 pushes all the other filters F toward the terminal end 33, causing the progressive expulsion of one filter F at a time to the user machine 101.
  • each detection device 34 is connected to the management and control unit 30 to provide the data detected.
  • the management and control unit 30, on the basis of this data, commands the delivery of one or more streams of air by one or more delivery nozzles 24, possibly by intervening on the selector members 29.
  • the user machine 101 can comprise at least one of either a reception station, a cutting station, a separating station, a removal station, a station to assemble the filters F, or a combination of said stations.
  • the apparatus 100 would be particularly bulky and difficult to manage and maintain. Furthermore, the installation of the feed unit 10 on the operating machine 101 could compromise the functioning of the latter, for example by affecting the movement inertias of the user machine 101 itself.
  • the user machine 101 comprises a reception station 102 to receive the filters F installed on a support structure 36, in which the filters F are discharged from the transfer pipes 31.
  • the filters F are cut to size, to define a semi-finished article, that is, a filter element 104 to be used, for example, in encapsulated articles C or in other types of articles, for example cigarettes.
  • the reagent product 107 can be tobacco, or another substance, according to the destination and/or use of the encapsulated article C.
  • the bottom of the capsule 105 is provided with holes for the passage of air, vapors, or suchlike through them, and to prevent the leakage of the reagent product 107.
  • An annular holding element 108 is associated with the capsule 105 and is configured to hold inside it the reagent product 107 and the filter element 104.
  • the production of the encapsulated article C in the apparatus 100 provides to carry out at least the following operating steps: providing at least one capsule 105, inserting inside it a dose of reagent product 107 suitably measured, inserting the filter element 104 sized according to production needs, closing the capsule 105 with the holding element 108, and providing the encapsulated article C obtained to other work stations in order to perform any other possible working steps.
  • one feed unit 10 can be used to feed several user machines 101, for example providing that a first group of transfer pipes 31, or at least one pipe, is connected to a first user machine, and that a second group of transfer pipes 31, or at least one pipe, is connected to a second user machine.
