Definitions

  • the present invention relates to a production system for producing activated charcoal filters according to the preamble of claim 1.
  • the invention also relates to a corresponding method for producing activated charcoal filters.
  • Activated carbon filters are used as filters for tobacco products, for example as pipe filters, cigarillo filters or cigarette filters.
  • the smoke is guided along the porous pieces of carbon as if through a labyrinth, so that a large part of the harmful substances remains in the filter.
  • the DE 10 2019 113 489 B3 a device for producing a filter for smoking articles is known.
  • the device has a rotary indexing table there, which carries holding devices for sleeves arranged in a circle.
  • the rotary indexing table transports a pair of sleeves picked up in the pick-up positions from one processing station to the next.
  • the device has a first tube stuffing station, a filling station and a second tube stuffing station as processing stations, the tubes being processed in pairs at the individual stations.
  • the DE 10 2019 113 489 B3 also describes a corresponding method for producing a filter for smoking articles.
  • the known device for producing a filter has the disadvantage that the device shown there requires a lot of space due to its structure.
  • not all parts of the machine are easily accessible for maintenance and repairs.
  • an oscillating conveyor arranged in the middle of the rotary indexing table is hardly accessible.
  • the solution according to the invention consists in particular in specifying a production plant for the production of activated carbon filters, the production plant having at least the following stations: a sleeve feed station for feeding sleeves; a first cap insertion station for inserting under caps into the sleeves; a filling station for filling activated carbon into the sleeves; and a second cap inserting station for inserting top caps into the sleeves, the manufacturing system having an endless conveyor which has a plurality of sleeve receiving devices and is adapted to move the sleeves in a conveying plane by means of the sleeve receiving devices, the sleeve receiving means preferably being adapted to hold the sleeves during insertion of the bottom cap and/or during insertion of the top cap.
  • the endless conveyor is designed as a chain conveyor, belt conveyor or belt conveyor. So more generally as a conveyor with an endless loop and flexibility in the conveyor level.
  • the sleeves are preferably sleeves made of paper or cardboard.
  • the sleeve is held in an upright position in the sleeve receiver.
  • the caps can preferably be made of ceramic.
  • the caps, in particular ceramic caps preferably have openings through which, for example, carbon particles can be sucked out later. In particular, between 2 and 9 such openings are provided here.
  • the shape of the openings is arbitrary. For example, these are designed as round holes or slots.
  • the caps are designed as cellulose caps.
  • the endless conveyor is also preferably driven by a drive, in particular a motor, and moves the sleeve receiving devices within the conveying plane. This means that processing at the individual stations also takes place within the conveyor level.
  • the drive axis of the endless conveyor is aligned perpendicular to the conveying plane.
  • the manufacturing facility can have a manufacturing table on which the stations can be arranged.
  • the conveying plane is preferably aligned parallel to a tabletop of the production table.
  • the sleeve receiving devices are particularly preferably designed to hold the sleeves during all work steps, ie from feeding in the sleeve to removing the sleeve.
  • the object is achieved in a satisfactory manner with the production plant according to the invention for the production of activated carbon filters.
  • a production facility for producing activated carbon filters is provided which is extremely space-saving and in which all parts are easily accessible.
  • the endless conveyor When designed as a chain conveyor, belt conveyor or belt conveyor, i.e. as a conveyor with an endless loop and flexibility in the conveying level, the endless conveyor can be flexibly and optimally adapted to the space available in the production plant. In the Compared to a rigid conveyor, such as a rotary table, the use of a flexible endless conveyor is significantly more unrestricted.
  • the endless conveyor is particularly preferably designed as a chain. A particularly simple attachment of the sleeve receiving devices is then possible.
  • the endless conveyor includes a plurality of means for releasably attaching the sleeve receiving means.
  • the sleeve receiving devices are thus interchangeable.
  • defective parts can be exchanged more easily and on the other hand, the production system is more universal and can process sleeves with different diameters.
  • the filter sleeves can have diameters in the range of 5 to 9 mm, purely by way of example.
  • the conveying plane is a horizontal plane.
  • a particularly advantageous embodiment of the present invention provides that the direction of insertion of the lower caps and the direction of insertion of the upper caps are aligned orthogonally to the conveying plane.
  • an anvil can be arranged as a counterpart from above.
  • an anvil when inserting the top cap, an anvil can be arranged as a counterpart from below.
  • the filling direction is also particularly preferably orthogonal to the conveying plane. This makes it possible to arrange the stations below or above the conveyor level or the endless conveyor. This ensures a simple and space-saving construction. Transferred to a production table, the conveying level thus runs at such a distance from the table that stations can be arranged below the conveying level.
  • the direction of insertion of the lower cap is oriented in the opposite direction to the direction of insertion of the upper cap.
  • the advantage here is that the sleeve no longer has to be moved during processing, and in particular no longer has to be rotated.
  • a further embodiment of the present invention provides that the sleeve receiving devices each have a base body and a pivoting body, the pivoting body being mounted on the base body so that it can pivot about a pivot axis, the pivoting body being in a pivoting plane between a holding position in which a sleeve is attached of the sleeve receiving means, and is pivotable to a release position in which a sleeve can be fed or removed.
  • the base body is attached to the endless conveyor. Due to the swivel body, the sleeve receiving device is designed to receive sleeves of different sizes. In addition, this allows the sleeves to be held securely and easily picked up and released.
  • the pivoting plane is parallel to the conveying plane or corresponds to the conveying plane.
  • the sleeve receiving device has a pretensioning element which holds the pivoting body in the holding position.
  • the sleeve receiving devices have to be moved into the release position in one pass, ie from the insertion of a first sleeve until the renewed insertion of a further sleeve into the same receiving device, for receiving and for dispensing the sleeve, ie twice into the release position. It is therefore advantageous if the receiving device is otherwise held in the holding position.
  • the pretensioning element used for this purpose is preferably designed to be elastically deformable. It is particularly preferably a spring, in particular a compression spring.
  • the production plant has at least one driver which is designed to come into contact with the pivoting body in order to move the pivoting body into the release position.
  • the driver is designed to actuate the pivoting body in such a way that it moves into the release position.
  • the driver is used to control the pivoting body. From the release position to the holding position, the pivoting body is moved by means of the biasing member when the operation of the driver is interrupted.
  • a corresponding driver is preferably arranged at the tube supply station and a corresponding driver at the tube discharge station.
  • a stop element can be formed on the pivoting body, which is designed to come into contact with the driver.
  • the stop element can be designed as a body, for example a rod, which extends beyond the remainder of the sleeve receiving device.
  • the stop element can extend orthogonally to the conveying plane upwards or downwards.
  • the production facility also has a large number of test stations for detecting bad parts and a reject station for sorting out detected bad parts.
  • the test stations can have distance-measuring, preferably optical, detectors or sensors.
  • the test stations can be arranged in particular for checking the lower cap, the activated carbon that has been filled in and the upper cap. In particular, the test stations check the correct position of the two caps and the level of activated carbon.
  • An associated test station is preferably arranged correspondingly behind the first cap insertion station, behind the filling station and behind the second cap insertion station. The relative term "behind" means downstream as viewed in the flow of matter.
  • a carrier is preferably also arranged at the reject station.
  • the production plant has a cleaning station, which is arranged behind the filling station and is designed to blow or suck particles, in particular coal dust, out of the sleeve or the filter.
  • the cleaning in the cleaning station is preferably carried out by means of suction or extraction, since the electrically conductive carbon is not distributed in the system in this way.
  • the object is achieved by means of a method for producing activated carbon filters, the method having the following steps: feeding a sleeve at a sleeve feed station; inserting a bottom cap into the sleeve at a first cap insertion station; filling activated carbon into the canister at a filling station; inserting a top cap into the sleeve at a second cap insertion station; and removing the sleeve or the filter into a collection container, with the sleeve being moved between the stations by means of an endless conveyor designed as a chain conveyor, belt conveyor or belt conveyor, which has a large number of sleeve receiving devices and is designed to hold the sleeves by means of to move the sleeve receiving devices in a conveying plane.
  • an endless conveyor designed as a chain conveyor, belt conveyor or belt conveyor, which has a large number of sleeve receiving devices and is designed to hold the sleeves by means of to move the sleeve receiving devices in a conveying plane.
  • the sleeve remains in the sleeve receiving device from the time the sleeve is fed in until the sleeve is removed.
  • the sleeve when the sleeve is moved between the stations, at least one driver comes into contact with the sleeve receiving devices in such a way that a pivoting body of the sleeve receiving device is moved from a holding position, in which a corresponding sleeve is held, into a release position , in which a corresponding sleeve can be fed or removed.
  • the driver actuates the swivel body here.
  • moving the pivot body to the release position occurs at the case infeed station, the case outfeed station and optionally selectively at the reject station.
  • a cleaning step takes place in which the sleeve or the filter is blown out or sucked out at a cleaning station.
