Definitions

  • the present invention relates to a device for tensioning and closing a plastic strapping around a packaged product.
  • the present invention has for its object to provide a device of the type mentioned, which allows a perfect and safe severing of the upper band section without damaging the same even with very tight strapping.
  • the second clamping device ensures that, after the band tension has been reduced in the section of the strapping band lying between the friction welding device and the tensioning wheel, the full tension is maintained in the remaining section of the strapping band which is guided around the packaged goods. Reducing the belt tension has the further advantage that the upper belt end is below a certain level for the friction welding process as well Tension is present, which is, however, less than the tension existing at the end of the tensioning process.
  • the tensioning wheel is a slotted wheel which allows the strapping to be tensioned with very great tensile force.
  • FIG. 1 shows a side view of a tensioning and closing device 2 placed on a package 1, which is used for tensioning and closing a plastic strapping 3 which is guided around the package 1.
  • the device 1 has a first clamping device 4 for holding the initial section 3a of the strapping band 3 located below.
  • This clamping device 4 consists of a lower clamping element 6 fastened on a base plate 5 and a movable clamping foot 7.
  • the device 2 is further provided with a friction welding device 8 which has an upper welding jaw 9 and a lower welding jaw 10.
  • the upper welding jaw 9 is designed as a lifting and lowering clamp 9.
  • the lower welding jaw 10 is mounted in a mounting part 11 fastened to the base plate 5 and can be driven back and forth transversely to the longitudinal direction of the strapping band 3 by means of a drive mechanism (not shown).
  • the structure of the friction welding device 8 and the drive mechanism for the lower welding jaw 10 is explained in more detail in the already mentioned EP-OS 0188720.
  • the friction welding device 8 is assigned a cutting knife 12, which is used to cut off the upper band section 3b behind the welding point. This separating knife 12 can be driven back and forth synchronously with the lower welding jaw 10, as is also set out in more detail in EP-OS 0188720.
  • a tensioning device 13 which has a slotted wheel 14 and a tensioning lever 15, which is shown in FIG. 1 in its lower end position.
  • the slot wheel 14 is provided with two slots 14a and 14b, which are at right angles to one another, for inserting the strapping band 3.
  • the friction welding device 8 is preceded by a second clamping device 16, consisting of a lower clamping plate 17 and a lowerable clamping foot 18.
  • a separating device 19 Seen in the belt tensioning direction A behind the slot wheel 14, a separating device 19 is arranged, which serves to move the tensioning wheel 14 towards a supply roll, not shown to cut the running strapping 3 after the closing process has been completed.
  • the tensioning lever 15 is provided at its free end with a rotary knob 20, by means of which a switching device (not shown in more detail) accommodated in the tensioning lever 15 can be actuated, the functioning of which will be discussed in more detail below.
  • FIGS. 2-4 there is a U-profile 21 on the base plate 5, which is fastened to the base plate 5 with its base part 22.
  • the side walls 23 and 24 of the U-profile 21 serve as end shields for a shaft 25 which carries the slot wheel 14 and a ratchet wheel 26.
  • Slotted wheel 14 and ratchet wheel 26 are firmly seated on the shaft 25 and can thus be rotated together.
  • the ratchet wheel 26 forms part of a locking mechanism 27, which further includes a pawl 28. This pawl 28 is pivotally mounted on an axis 29, which is in storage 30 is held.
  • the shaft 25 also carries a control disk 32 which is mounted on a hub 33 which is arranged on the shaft 25 in a freely rotatable manner.
  • the control disk 32 has a control cam 32a (FIG. 2) which serves to push the pawl 28 away against the force of the leg spring 31 and to disengage the nose 28a of the pawl 28 from the ratchet wheel 26.
  • a brake arrangement 34 (FIGS. 3 and 4) designed as a friction brake is arranged on the end of the shaft 25 opposite the slot wheel 14.
  • This brake arrangement 34 has a brake disk 35 which rotates with an extension 25a of the shaft 25 and which is pressed by means of plate springs 36 against a brake plate 37 which is anchored to the base plate 5.
  • the plate springs 36 are preloaded by means of a washer 38 and a screw 39.
  • the clamping device 16 is activated in a manner not shown in the figures after the end of the tensioning process, i.e. the clamping foot 18 lowered.
  • the tensioning lever 15 is pivoted again in the direction of arrow C into the starting position shown in FIG. 1, in which the switching device is actuated by turning the rotary knob 20.
  • This changeover device disengages one driver pawl from the ratchet wheel 26, which is prevented from turning back by the pawl 28.
  • the other driver pawl is brought into engagement with the control disk 32, which is now rotated counterclockwise (arrow F in FIG. 2) by pivoting the tensioning lever 15 again in the direction of arrow B.
  • the control disk 32 activates the second clamping device 16, which clamps the strapped strap 3 and holds the strap tension applied by the tensioning device 13.
  • the tensioning lever 15 is pivoted back into its lower end position in the direction of arrow C, with the result that the clamping devices 4 and 16 are released and the upper welding jaw 9 is raised .
  • the separating device 19 is actuated to remove the piece of tape 1 deformed in the region of the slotted wheel 14 from the tape supply cut off.
  • the slotted wheel 14 is rotated back into its starting position, in which an easy insertion of the strapping 3 is possible for the next tensioning and closing process. This positioning of the slot wheel 14 is explained in more detail in EP-OS 0284798.
