Definitions

  • the invention relates to a device for feeding bobbins of packaging material to a bobbin changing device of a packaging machine according to the preamble of patent claim 1.
  • Efficient packaging machines must be provided with sufficient packaging material.
  • tin foil In the case of cigarette packaging machines, tin foil must be made available as the inner wrapping of the cigarettes, paper (for soft cup packs) and cellophane or plastic film. This material is usually attached to the packaging machine as a wound roll (bobbin) and drawn off according to the consumption of packaging material.
  • the bobbins are rotating by one-sided supported trunnions added, which enter into a central opening of the bobbin formed by a cylindrical core (usually cardboard core).
  • the invention is concerned with the largely automatic feeding of bobbins to a packaging machine and with the transfer thereof to a bobbin changing device of the packaging machine equipped with trunnions.
  • bobbins are conveyed from a horizontal plane by means of a pivotable device into a plane perpendicular thereto and are fed to a receptacle with trunnions.
  • the receptacle also contains a complex locking and positioning mechanism to hold the bobbin in the ultimately desired position.
  • a device is known from EP-A-0 155 863, in which a bobbin carrier that delivers a bobbin is axially displaceable.
  • the invention has for its object to ensure a reliable, efficient transfer or transfer of the bobbins without manual intervention.
  • the object is achieved by the characterizing features of patent claim 1.
  • a transversely projecting, likewise axially displaceable conveyor support bolt for receiving the bobbin is arranged on the pivotable bobbin conveyor arm during the transfer.
  • the bobbin conveyor arm is moved with a (new) bobbin in front of the trunnion to be loaded in the bobbin changing device in such a way that the trunnion and the conveyor trunnion are axially aligned, with free end faces adjacent to one another.
  • the trunnion to be loaded is now extended in the axial direction, while the conveyor trunnion is withdrawn to the same extent.
  • the bobbin is handed over without moving it. Manual intervention is not necessary for this.
  • the handover of the Bobine in a particularly reliable way.
  • the trunnion or conveyor trunnion can be driven in a suitable manner to carry out the axial movements.
  • the support pins of the bobbin changing device are preferably actuated by compressed air, while the conveyor support pin of the bobbin conveyor arm is adjusted mechanically or electromechanically by an electric motor via a gear transmission.
  • the trunnions of the bobbin changing device are equipped with other special features.
  • a tensioning brake is integrated with the trunnion, which is actuated in accordance with the tension determined in the running web to ensure that the web is always conveyed with approximately the same tension.
  • the trunnions are in the area of the bobbin system with radially movable clamping members for releasable Fix the bobbin provided. According to the invention, these are actuated pneumatically, specifically via the support pin or a piston rod assigned to it.
  • the bobbin conveyor (bobbin conveyor arm) is assigned a pre-conveyor which is able to accommodate a plurality of bobbins and thus serves as a bobbin store.
  • the respective front bobbin on the pre-conveyor is fixed in a take-over position so that the conveyor support pin of the bobbin conveyor arm can enter the center opening of the bobbin by radial movement.
