Definitions

  • the invention relates to a tensioning device for a packaging tape according to the preamble of claim 1.
  • the present invention relates to a tensioning device, it is also applicable to a combined tensioning and closing device for a plastic band.
  • the device is known from EP-A1 0 188 720. It is used for strapping a package or several objects to be bundled with a thermoplastic plastic band.
  • a slit wheel with crosswise slots is used to tension the belt.
  • the slot wheel is rotatably connected to a ratchet wheel, which is carried along in the tensioning direction when the actuating lever is moved back and forth. After the tensioning process is finished, the ends of the tape are welded together. The welding can be done with the above-mentioned combined device, but it is also possible to use a tensioning device and a closing device.
  • the slot wheel is in the last position reached during tensioning. Since the ratchet wheel has a relatively fine tooth pitch, a variety of positions are possible. If, for the next tensioning process, the strap is to be reinserted into the slot wheel after the package has been strapped, then this often does not have the appropriate position for insertion, so that it must first be rotated by hand into the appropriate position. This is cumbersome and time-consuming for the operator, since both hands are normally already strained.
  • the invention is therefore based on the object of creating a tensioning device in which the insertion of the tape into the slotted wheel is more user-friendly.
  • the slitting wheel is brought into the position required for inserting the tape without additional actuation, without a second ratchet wheel being required for this purpose.
  • the invention is not limited to the expansion of the known device, but is also useful and advantageously applicable to new designs.
  • a tensioning and closing device 10 is placed on a package 12 in order to weld a thermoplastic plastic band 14 around the package 12 at its ends 14 ′ and 14 ′′.
  • the tensioning and closing device 10 has one in the tensioning direction 16 seen, in front of a welding device 20 arranged for tensioning the belt 14 slit wheel 18.
  • the slot wheel 18 has laterally open slots 18 'arranged crosswise for inserting the tape 14. If the slotted wheel 18 is now rotated counterclockwise, the inserted tape is tensioned in the tensioning direction 16.
  • the actuating lever 28 has a handle 32 which can be rotated about its axis for actuation and thereby actuates a switching device 112, 113 via a switching rod 114.
  • this switching device either the driver pawl 110 for engaging on the ratchet wheel 58 or a second driver pawl 111 arranged behind it on the same axis for engaging a cam disk 60 is released.
  • a return spring 116 is used to reset the switching device 112, 113, 114.
  • a second pawl 120 which interacts with the cam disk 60.
  • a release lever 122 which can be pivoted about a shaft 48, acts against the force of a rotation by means of a roller 124 arranged on the actuating lever 28 spring 108 is pivoted clockwise.
  • the essential elements of the tensioning and closing device 10 are built on a base plate 96, with which the device is also placed on the package 12.
  • the plastic band 14 to be processed is drawn off from a symbolically represented supply roll 40 and, after the wrapping of the package 12, is inserted into the welding device 20, into one of the slots 18 ′ of the slot wheel 18 and into a separating device 34. Since the other functions are not important for the present invention, reference is made to the already mentioned EP-A1 0 188 720.
  • FIG. 2 shows the parts essential for the invention on a larger scale than in FIG. 1.
  • the switching device already mentioned for FIG. 1 has two sliders 112 and 113 which are displaceably mounted in the actuating lever 28, of which, depending on the position of the rotatable handle 32 according to FIG. 1, either the slider 112 with the driving pawl 110 or the slider 113 with the second driver pawl 111 cooperates.
  • the two driver pawls 110 and 111 are mounted independently of one another on the same shaft 109 and are biased counterclockwise by tension springs 134 and 136, respectively. In the position shown in FIG.
  • the driver pawl 110 is lifted off the ratchet wheel 58, while the second driver pawl 111 interacts with the associated cam disk 60.
  • the process of tensioning the plastic belt (not shown in FIG. 2) has ended, but the belt tension is maintained by the slotted wheel 18, since this is locked by the pawl 118 engaging the ratchet wheel 58.
  • the pawl 118 is under the force of a torsion spring 119.
  • the second driver pawl 111 mounted on the actuating lever 28 engages with its nose 111 'on the flank 60' of the cam disk 60 in order to turn the cam disk in the counterclockwise direction.
  • the cam disk 60 lifts the pawl 118 from the ratchet wheel 58 with its curve 60 ′′.
  • the ratchet wheel 58 is now freely rotatable.
  • the pawl 118 engages at offset 60 according to FIG The position reached thereby serves to release the welding process.
  • the nose 139 of a reset lever 138 engages one of the restoring teeth 59 protruding radially beyond the remaining teeth of the ratchet wheel 58 and thereby rotates the ratchet wheel 58 clockwise until the second driving pawl is switched over 112 111 disengages the reset lever 138 from the ratchet wheel 58 by means of a driving pin 140.
  • the switching device 112, 113 is reset when the actuating lever 28 is depressed by a switching pawl 142 shown in FIG. 1 by means of the return spring 116.
  • the release lever 122 which can be pivoted about the shaft 48 fixed to the housing, is pivoted counterclockwise against the force of its return spring 108 by the actuation lever 28 by the roller 124 mounted on the actuation lever 28 rolling on a curve 123 of the release lever 122.
  • the release lever 122 engages with the catch 122 ′ on the pawl 118 in order to lift it off the ratchet wheel 58.
  • FIG 3 shows a partial top view of the elements arranged in the actuating lever 28.
  • the sliders 112 and 113 of the switching device have been omitted.
  • the automatic or semi-automatic positioning of the slot wheel in the position most favorable for inserting the tape is not limited to a direction of rotation opposite to the tensioning direction, but can also be carried out by a forward rotation of the slot wheel which corresponds to the direction of rotation during tensioning. It is also not necessary to lift the driver pawl 110 and the pawl 118 off the ratchet wheel. It is also conceivable to uncouple the slot wheel for positioning from the ratchet wheel, so that it is also not necessary to lift the pawls mentioned.
  • the positioning is carried out by actuating the ins especially for the tensioning of the operating lever, so that no additional operating elements are required for the positioning process.
