Definitions

  • the invention relates to a device for the production of bubble envelopes according to the preamble of claim 1.
  • bubble envelopes are increasingly used for the mailing of products that are sensitive to pressure or shock.
  • Such a device is already known from DE-OS 2 629 679.
  • This previously known device has a paper unwinding device for a single paper web and an air-cushion film unwinding device for a single air-cushion film web, the air-cushion film web fastened to the paper web by means of transverse sealing at the edge being folded over into a half-tube in a folding station.
  • a disadvantage of this previously known device is that only one mailing bag can be produced in one work cycle, which does not have a relatively firm edge zone on all sides as lateral protection against impacts. Furthermore, in the previously known device, the occurrence of a relatively large broke is recorded, for which the occurrence of tensions during the sealing of the paper web with the bubble wrap web and the subsequent folding is responsible. Another disadvantage is that a format change in the mailing bag to be produced can only be carried out in a relatively complicated and time-consuming manner.
  • DE-OS 2 164 152 describes a protective container and a method for producing it in the form of a mailing bag, in which side edge sealing is disclosed, but on the other hand, because of the folding process, it is not possible to produce mailing bags with a stable edge area on all sides.
  • US Pat. No. 3,896,712 discloses a device for the automatic production of letter envelopes which has a simple format adjustment by means of rotatable pinions which engage in a system with racks and spindles. There is no reference to the special production of bubble envelopes and the associated problems.
  • the invention has for its object to develop a device of the type mentioned in such a way that mailers of different formats can be produced with as few rejects as possible during a work cycle.
  • an apparatus for producing air cushion mailing bags is advantageously created, in which two or more padded mailing bags can be produced in one work cycle.
  • the relatively firm edge zones on each mailing bag which serve as lateral protection against impacts, help to reduce the amount of scrap in production.
  • the sealing of the bubble wrap with the paper web has a significant share in the reduction of rejects and thus serves to improve the operational safety of the claimed device.
  • the large-area sealing provided also advantageously allows a reduction in tensions between the paper webs and the bubble wrap webs and thus also contributes significantly to the operational reliability of the device and the reduction in rejects.
  • the production of different mailing bag formats is considerably simplified due to the overall concept.
  • a web guiding device for the correction of a course of the two connected paper webs is arranged in front of the cutting device, which advantageously contributes to the fast and reliable production without rejects, because before the cutting device there is an effective correction of the paper webs connected to the sealed air-cushion film webs.
  • Cooling devices are preferably arranged downstream of the longitudinal and transverse sealing devices in order to ensure reliable sealing and to further increase manufacturing reliability.
  • a PTFE lance preventing the pocket openings from being sealed is preferably provided between the two air cushion film webs in the case of longitudinal sealing, wherein, in addition, when longitudinally sealing the paper web, for each longitudinal sealing device, one is preferably attached, adjustable, and adjustable for each longitudinal sealing device the sealable surface of the windable PTFE sheet is provided to prevent contamination or sticking.
  • a cut-to-length setting device and a setting device for mailing bag formats are provided for adapting the device to different mailing bag formats, the size setting device having toothed racks in the running direction and transverse to the running direction of the paper web, and the toothed racks also being connected to sealing elements of the sealing devices and cooling elements comb the adjustment pinions mounted on the cooling devices. It is furthermore advantageous if measuring scales fixed to the device are provided on both sides of the running direction of the paper web, at least for the setting control of the landscape format.
  • a photocell control for section determination is preferably provided for the cross cutting of the mailing bags, with which touch can be worked easily and quickly.
  • the transport of the paper web sealed with the bubble wrap webs is preferably carried out by means of traction rollers which engage a longitudinal sealing seam produced within the paper web and on the lateral edges of the paper web, preferably the web guiding in the edge region of the sealed paper web, in each case one driveless guide roller inclined outward in the web running direction and one has associated drive-less pressure roller which is inclined outwards in the paper web running direction, the pressure roller only engaging the other opposite edge of the paper web when the paper web runs out, and the pressure duration of the pressure roller being adjustable by a timer.
  • a photocell is advantageously provided on each edge, by means of which signal the pressing of the pressure roller provided for the other opposite edge can be actuated via an electrically controlled compressed air cylinder.
  • a punching device for producing flap closure holes and for chamfering the closure flaps is arranged upstream of the web guiding device in the direction of travel of the paper webs, the toothed racks having pinions which mesh with them and can be actuated for adjustment, and have a measuring scale.
  • the air cushion mailing bags are composed of paper webs and air cushion film webs and are produced by a plurality of devices which are arranged contiguously in a transport direction.
