Definitions

  • the invention relates to a bobbin splicing device for wrapping webs on packaging machines, in particular cigarette packaging machines, with two feed webs opening into a common feed line for one wrapping web each, a pair of rollers being arranged at the start of the common feed line, and with one knife each for both wrapping webs.
  • bobbins made of wrapping paper or film are often used for wrapping objects to be packaged, from which the webs are drawn off via feed rollers and sections are separated by means of a knife and fed to a packaging station.
  • This is the case, for example, with cigarette packers in which both the so-called inner paper and the outer transparent film and, in the case of soft packs, also the so-called outer paper are fed to a packaging station in this way.
  • a bobbin splicing device in which rotatable arms are provided, each of which carries a knife in the direction of rotation in front of a first section and furthermore has a second section which is offset by approximately 180 ° to the first, wherein at Rotating the arms engages a first and a second section with each other and clamp the sheathing web to be cut by the knife between them.
  • the object of the invention is therefore to create a bobbin splicing device of the type mentioned at the outset which enables an automatic connection of two envelope web ends.
  • a clamping strip cooperating with a support is provided for each envelope before entering the gap of the roller pair, that the clamping strips can be ventilated both manually and via cam drives coupled to the shafts of the rollers, that the rollers are each one Knife, in the direction of rotation in front of this a first elastic jacket section and offset by approximately 180 ° to this, wear a second jacket section, the first and second jacket sections protruding from the circumference of the roll and engaging with one another under pressure during the roll rotation and that the rollers are mounted so that alternately a first and a second jacket section meet.
  • Fig. 1 shows a front view of a bobbin splicing device.
  • Fig. 2 shows a detail of a view of the device of Fig. 1 from the right.
  • the device shown comprises a rear wall 1 and two front wall sections 3 connected to it via spacer bars 2.
  • the rear wall 1 is used to support two shafts 4, each via a bearing holder 5, which receives a roller bearing 6.
  • the two shafts 4 each carry a gear 7, the two gears 7 meshing with one another and a gear 7 being drivable via a drive pinion 8.
  • Each shaft 4 carries a change roller 9.
  • the diameter of the change rollers 9 is such that there is a wide gap between the two change rollers 9.
  • Each interchangeable roller 9 is provided with a stop 10 in the form of an axially extending cutout and also carries a knife 11, which runs somewhat obliquely to the surface line of the interchangeable roller 9, and two jacket sections 12 and 13 made of an elastic material such as rubber or the like, of which one in the direction of rotation 14 of the change rollers 9 in front of the knife 11 and the other offset by approximately 180 ° with respect to the former on the circumference of the change roller 9.
  • the elastic jacket sections 12, 13 have such a thickness that they come into engagement with one another under pressure during the rotation of the change rollers 9.
  • the two change rollers 9 are mounted offset from one another by 180 °.
  • two supports 15 which are inclined towards the roller gap and tangential to the outer circumference of the change rollers 9 formed by the supports 12, 13 are mounted between the rear wall 1 and the front wall sections 3.
  • Each support 15 interacts with a clamping bar 17 provided with a friction-increasing cushion 16 made of elastic material, which is fastened between two arms by two angle levers 18, which are rotatable about an axis 19 mounted in the rear wall 1 and the front wall section 3.
  • a helical spring 20 attached to the front wall section 3 engages in order to pretension the clamping strip 17 in the clamping position against the support 15.
  • a hand lever 21 is provided on the one hand, which sits on a shaft 22 which is in the rear wall 1 and in the each front wall section 3 is mounted and bears a curve 23 which cooperates with a stop 24 located here on the spring-biased arm of the angle lever 18 and designed here to be adjustable.
  • a hand lever 21 which is pivotable by more than about 120 ° from an approximately downward position to a somewhat oblique, substantially vertical position, this pivoting being limited by a pin 25 located on the respective front wall section 3, so that there are two stable positions for the hand lever 21, the terminal block 17 is vented via the curve 23 and the stop 24 engaged therewith.
  • a lever 26 sits on the shaft 19, which is connected to a roller 27 which rolls on a curve 28 which sits on the shaft 4 and has two diametrically opposite circumferentially projecting areas. By rotating the shaft 4, the terminal block 17 can therefore also be released via these projecting areas.
  • bobbin holders for the inner paper wrapping (but also for the transparent film or outer paper wrapping), which are appropriately equipped with wrapping lane bobbins.
  • the wrapping web 29 is threaded from a bobbin over the support plate 15 through the gap between the changing rollers 9 and further into the area of a packaging station, for example in the form of an enveloping revolver between corresponding rollers.
  • the wrapping web 30 from the other bobbin is only guided to the stop 10 of the second change roller 9 with the clamping bar 17 lifted by the hand lever 21, the stop 10 being located in the area of the roller gap.
  • the free end of the web 30 is provided with an adhesive strip 31 and fixed by turning the hand lever 21 through the clamping strip 17, while the opposite clamping strip 17 remains ventilated via the associated curve 28.
  • the web 29 is drawn off through the wide open nip of the rolls until the end of the running bobbin is reported by an appropriate control. This has the effect that the machine speed is reduced and the change process is initiated when a specified target speed is reached.
  • the change rollers 9 are switched on electronically and begin to transport both tracks 29, 30, since the previously unvented clamping strip 17 is also lifted by turning the curve 28.
  • the other clamping strip 17 begins to move into the unventilated position due to the rotation of the associated curve 28, in order to clamp the web 29 shortly thereafter.
  • the two tracks 29, 30 are between the jacket section 12 one interchangeable roller 9 and the jacket section 13 of the other interchangeable roller 9, so that the two webs 29, 30 are glued together under the pressure of the elastic jacket sections 12, 13 via the adhesive strips 32.
  • the knife 11 of the one interchangeable roller 9 engages with the web 29 and cuts it, so that the end of the web 29 located in the nip and leading to the packaging station is only connected to the start of the new web 30.
  • the empty bobbin can then be replaced and the new web can be threaded again up to the corresponding stop 10 with the application of an adhesive strip 31 and with clamping using the corresponding clamping strip 17, in order to be exchanged for this at the end of the web 30.
  • a further curve 32 is provided on the shaft 4, provided with two indentations offset by 180 ° to one another, which engages with a roller 33 which is at the free end of an arm an angle lever 34 is attached, which is also seated on the shaft 19. Furthermore, the other arm of the angle lever 34 is connected to the rear wall 1 via a helical spring 35 and is therefore preloaded accordingly.
  • the change rollers 9 are electronically disengaged when the next change position is reached and are fixed in the corresponding change starting position by the cam mechanism 32, 33, 34, 35.
  • the roller 33 is held in the respective depression of the curve 32.
  • the cam mechanism only needs to be provided for a change roller 9.
  • the supports 15 can additionally be provided with elastic, friction-increasing strips 36 adjacent to the pads 16.
  • one jacket section 12 or 13 can be designed as a heating element, while the other is elastic, so that the two envelope sheets to be spliced are brought into contact between an inelastic, metallic heating element and an elastic element and be welded. The welding then replaces the adhesive strip 31.
