Definitions

  • a strapping tool has a pair of strap/gripping [54] STRAP 2 FOR TENSIONING TOOL members mounted for swinging about a common axis. An end 5 Cm of the strapping is gripped by one of the members againsta [52] 0.8. 254/79 stationary foot and another portion of the strapping is gripped [51] Int. Cl 136613/00 between the two members so that it can be pulled in tension- [50] Field of Search 254/51, 52, ing direction but cannot loosen. There is a single lever for sequentially releasing the two gripping members.
  • PATENTED DEB 8197B sum 1 OF 2 'iurele'ased position; and- I directed comprises a gripper for' holding one end of strapping and tensioning means for tightening the strapping about an object-with a portion of strapping leading to a supply overlapping a portion adjacent the held end.;Although not necessary to'the present invention, the tool usually also comprises means for securing the overlapping portions together and means for severing .the [strapping looped about the "object from the v strapping leading to a supply. There are on the market a varietyiof tools for carrying out theseffunctions.
  • FIG. 1 is a side elevational view of a'strapping toolembodyingth'e invention
  • FIG. .2 is a section taken along'the line II-II of FIG. 1;.
  • FIG. 3 is a sectional view takenalong the'line III-III of FIG.
  • FIG. 4 is'a fragmentaryside elevational view showing the strap gripping elements in gripping position
  • FIG.J6 is a vicw-partially in end erevasan in partially in r I sectionand showing strap gripping elements of the present invention.
  • the tool comprises a main frame generally indicated at 10 for supporting the various operating parts including a tensioningrneans indicated generally at 1 2 and a sealing vmeans indicated generally at 14 for securing together overlapping portions of the strapping after the strapping,'which is id indicated. at 18, has'been tensioned about an object such as a bolt partially shown at 20.
  • the tool includes a cutter, not shown, for cutting the strapping adjacent thesealing means and between the sealing means and the ten sioning means.
  • a gripping member22 squeezes an end portion of. the strapping against a foot 24(see FIGS.'4 and 5) provided on the main frame so as to'hold the 'end of the strapping againstmovement while his beingtensioned.
  • the tensioning means maybe relaxed or released'so that the strapping is not under tension between it and the gripping member 26 butis held under tension about the object 10.
  • both gripping members 22 and 26 are mounted for swingingmovement about axes which are parallel to the foot 24,.
  • member 22 includes'a hollow cylindrical portion 28 which is rotatably mounted inthe stationary framework of the tool and member 26 includes a solidcylindrical shank 30 rotatably mounted within the hollow cylindrical portion 28. While it is not essential that the swinging axis of member 26.thus coincides with the swinging axis of member 22', such arrangement is preferred.
  • Member 22 has a knurled, serrated or otherwise roughened surface 32 for engaging the upper side of the end portion of the strapping and sw squeezing it against the foot 24 when said member is swung in a first direction (clockwise as viewed in FIGS. 1, 4 and 5).
  • the swinging axis of member 22 is located close enough to the foot 24 thatsaid member will contact the foot when swung clockwise if no strapping is located therebetween.
  • the roughened portion 32 is spaced a nonstrap-engaging distance from foot 24 when member 22 is swung in a second direction, as shown in FIG. 4 and as will presently be explained.
  • the strapping From the end portion clamped between member 22 and foot 24, the strapping extends beneaththe'se'aling means 14, over a corner 34 of the framework 10 and thence around the object 20 being strapped. After being encircled about the object, a portion of the strapping positioned between a roughened surface 36 of member 2.6and a smooth face 38 of member 22. Fromthat, point, the strapping extends beneath thesealing means 14 in overlapping relationship with the portion of the strapping adjacent foot 24 and then to the tension ing means 'l2'-and a supply of strapping not shown.
  • member 26 swings in the above referred to second direction
  • a Y Securedto the'hollow shaft 38 of member 22 is a cam 40 and secured to the cylindrical shank 30 of member 26 is a cam 42.
  • cams 40 and 42 are mounted sideby-side and a coiled spring 44 has an end secured to cam'40' and the other end secured to cam 42.
  • Spring- 44 is nndersome stress and urges member 22 clockwise and member 26 counterclockwise so that the roughened pori portion 36 of the latter normally engages the smooth portion'38 of the former.
  • spring 44 not only serves to normally hold the roughened portion 36 of member 26 engaged with the smooth portion 38 of member 22 but is also effective to normally hold member 22 to the FIG. 4 position.
  • an operating lever 50 Secured to a shaft 48 rotatably mounted in the framework 10 of the tool is an operating lever 50 having formed thereon or secured thereto adjacent the hub a nose 52'underlying and engaged with cam 42 and a now nose 54 aligned with but nor framework. The opposite end. of pin 56 is aligned with cam 40.
  • lever 50 The normal inactive position of lever 50 is shown in full lines in FIG. 3 and the active position thereof is indicated in dotted lines.
  • lever 50 When the tool is to be put-to use, lever 50 is swung counterclockwise from thefull line position to the dotted line position of FIG. 3. This movement first causes the nose 52 to rock cam 42 clockwise and subsequently causes nose S4 to shove pin 56 toward the right whereby the pin rocks cam 40 counterclockwise. Gripping members 22 and 26 are thus positioned as shown in FIG. 5 The movements of said gripping members take place in sequence with member 26 moving first. An end portion of the strapping 18 is then positioned between foot 24 and the roughened portion 32 of member 22 and and member 22 is permitted to swing clockwise so as to grip the strapping. This clockwise swinging of member 22 is brought about by the spring 44 when pressure on operating lever 50 is relaxed.
  • lever 50 is not permitted at this time to move all the way to the full line position of FIG. 3 so therefore even with member 22 restored to the FIG. 4 position, member 26 remains in the FIG. 5 position.
  • lever 50 is further relaxed so as to permit spring 44 to swing member 26 to the FIG. 4 position whereby a portion of the strapping is gripped between the members 22 and 26.
  • the strapping is gripped between members 22 and 26.
  • the tensioning means may be of the type generally indicated in FIG. 1, where tension is intermittently and manually applied to gradually tighten the strapping or it may be power driven so as to continuously draw the strapping tight once it has been activated.
  • gripping member 26 is free to swing in the direction of the tensioning means to permit the strapping to slide over the relatively smooth surface 38 of member 22 during the tensioning operation.
  • the tension of in the strapping due to engagement of the roughened surface 36 with the strapping, swings member 26 back to where the strapping is gripped between members 22 and 26.
  • the strapping is held under tension about the package 20 but that portion of it between gripping members 22 and 26 and the tensioning means 12 may be relaxed.
  • a strapping tool comprising a main frame, a strap engaging foot on said frame, a first gripping member mounted on said frame for swinging about an axis parallel to said foot, said member having a smooth face for engagement with a portion of strapping leading to a tensioning mechanism and having a roughened portion adapted to squeeze the end of a piece of strapping between it and said foot when said member is swung in a first direction, a said roughened portion being spaced a nonstrap-engaging distance from said foot when said member is swung ,in a second direction, a second gripping member mounted on said frame for swinging about an axis parallel to said foot,and said second member having a roughened portion adapted to squeeze the portion of strapping leading to a tensioning mechanism between it and the smooth face of said first member when said second member is swung in said second direction and to be spaced from said smooth face when said second member is su swung in said second swung in said first direction.
