Definitions

  • a push-type strap tensioning tool includes an elongated frame which provides an anvil section at a first end on one side thereof with the anvil section being positioned in opposed relationship with a strap feeding assembly pivoted on the frame.
  • the strap feeding assembly includes a knurled feed wheel biased toward the anvil.
  • a tension handle also pivoted upon the frame rotates the knurled wheel by means of a ratchet gear and pawl drive mechanism.
  • a lift arm in the form of a lever is pivoted on the frame rearwardly of the strap feeding assembly and the lever has one arm movable along an are which intersects an abutment portion of the strap feeding assembly.
  • the lever includes a second lever arm positioned in the path of travel of an abutment on the tension handle to pivot the strap feeding assembly and move the feed wheel away from the anvil to allow a strap to be easily inserted therebetween for tensioning.
  • the strap feeding assembly is progressively loaded to make it increasingly difficult for the lift arm to pivot the strap feeding assembly.
  • This invention relates to tensioning tools for tightening loops of metallic strapping around packages in order to bind and secure such packages. More specifically, the invention relates to a push-type tensioner which achieves tension by pushing against a seal after the seal is threaded on a strap, and the end of the strap is bent back under the seal.
  • Strap tensioning tools have long been used to tighten bands of strapping around objects of all kinds and have performed very well in difficult packaging situations, so that they have achieved a high level of acceptance. With the wide use of such tools has come the desire to maximize the speed with which the tools can be used in order to afford optimum production levels for packaging operations. Many tools commonly in use at the present time, while quite effective for their basic purpose, cause delays through a tendency to accidentally release the tension in the strap during the course of the tensioning operation. Accordingly, a need has remained for a tool which preserves all of the advantages of previous designs, yet allows quick loading of the tool without danger of sudden loss of tension and the consequent need to repeat the operation.
  • a strap tensioning tool which includes a frame having an anvil section and engageable at one end thereof with the seal.
  • the upper overlapping strap portion protruding beyond the seal and loop is positionable over the anvil
  • tensioning means also carried upon the frame, includes a movable tension handle, a strap feeding assembly having a strap-engaging member, means mounting the assembly for movement relative to the frame toward and from the anvil section, and means biasing the strap feeding assembly toward the anvil section to capture the protruding strap portion between the strap engaging member and the anvil section.
  • the tool also includes means for moving the strap feeding assembly away from the anvil, said means including a lift arm in the form of a lever pivoted on the frame at a point removed from the gripping assembly.
  • the lever has a first arm extending into the path of the tension handle, and a second arm movably engaging the strap feeding assembly and which upon movement of the handle into engagement with the first arm overcomes the strap feeding assembly biasing means and moves the strap feeding assembly relative to the frame to permit the protruding strap portion to be accepted between the anvil section and the strap engaging member, in this manner facilitating the initial loading of the tool.
  • the tool further includes a drive mechanism connected between the handle and strap engaging member to transmit a tensioning force in a direction away from the seal to the strap engaging member when the handle is moved relative to the frame.
  • a drive mechanism connected between the handle and strap engaging member to transmit a tensioning force in a direction away from the seal to the strap engaging member when the handle is moved relative to the frame.
  • FIG. 1 is a side elevational view of the strap tensioner tool of the invention showing the manner of its use with a package having a strap loop and seal, with the tool gripping the protruding free end of the strap loop and with the seal being shown in cross-section;
  • FIG. 2 is an enlarged side elevational view of the tool of FIG. 1 illustrating the tensioning handle in full lines in the strap gripping position and in broken lines in the strap loading position;
  • FIG. 3 is a partial side elevational view of the tool of FIGS. 1 and 2, showing the tool in the strap loading position;
  • FIG. 4 is a top plan view of the tool of FIGS. I through 3;
  • FIG. 5 is an enlarged cross-sectional view taken generally along line 5-5 of FIG. 4.
  • FIG. 1 shows the improved strap tensioning tool 10 which in general comprises a main frame 12 of elongated and generally narrow upright configuration which at the leading end thereof has a nose 14, and anvil portion 15 inwardly of the nose, and a gripping and feeding assembly 18 immediately above anvil portion and in opposed relationship thereto.
  • the feeding and gripping assembly 18 is pivoted to main frame 12 and carries a tension handle 20 extending outwardly therefrom and generally over main frame 12.
  • handle 20 is also used to pivot assembly 18 between a strap loading position (FIG. 3) to a strap gripping and feeding position (FIG. 2).
  • the tensioning tool is shown as it appears in use with a strap 22 disposed completely around a package or article 24 and a seal 26 for securing the strap loop in place.
  • Strap 22 is preferably metal, as is known in the art, while seal 26 is of the push-type also known in the art.
  • Such seals have legs 26a folded over and parallel with back 26b and spaced therefrom so that strap can be fed through the seal during the tensioning process.
  • FIG. 1 in use the free end of the strap is fed through seal 26, and the strap arranged in a loop about article 24 to provide an outer portion S" overlapping an inner portion S.
  • An end section S of inner strap S is folded under seal 26 so that it is held entrapped between the upper surface of package 24 and the facing lower surface of seal 26 as the strap is tensioned.
  • Outer strap portion S" is positioned between anvil portion and tensioner assembly 18 and the nose 14 of the tool butted against seal 26 to hold the seal against movement as the strap loop is tensioned by oscillation of handle 20.
  • Main frame 12 is relatively narrow in plan view compared to tensioner assembly 18, as may be seen in FIG. 4, and at the end 27 thereof opposite nose [4, it is manually graspable by the operator, with a gap being provided therefor between upper and lower longitudinal supports 28 and 30.
  • frame 12 includes anvil portion 15 extending orthogonally outwardly from one side 34 of frame 12.
  • Anvil portion 15 includes an upwardly facing surface 32 upon which is mounted wear plug 36, and which, when the tool is in use, supports the portion of outer portion S" of the strap which protrudes beyond seal 26.
  • the strap feeding assembly 18 is pivoted at the end of main frame 12 immediately inwardly of nose l4 and upwardly of anvil portion 15, and has drive section 38 (FIG. 4) and strap engaging section 39, respectively, on sides 34 and 34 of main frame 12.
  • strap feeding assembly section 39 is generally in opposed relationship with anvil portion 15, while the strap feeding assembly pivots in a limited arc transversely to the longitudinal direction of frame 12.
  • Spring 42 one end of which bears against a portion of frame 12, and the other end of which bears upon strap feeding assembly 18, serves to strongly bias the tensioner assembly toward the upper surface 32 of anvil portion 15.
  • Pivotally securing strap feeding assembly 18 to the frame 12 at the aforementioned pivot location is shaft 44. It passes transversely through the entire strap feeding assembly 18 and a portion 45 of main frame 12 adjacent nose 14 (see FIG. 4), so that its axis is perpendicular to the longitudinal axis of main frame 12. It is spaced upwardly from both anvil 15 and nose 14 and located generally therebetween laterally.
  • Drive section 38 of strap feeding assembly 18 is open at the top thereof to permit tension handle to be mounted pivotally on shaft 44 and protrude outwardly from strap feeding assembly section 39.
  • Drive handle 20 is bifurcated at the pivoted end thereof to permit ratchet gear 46, which is rotatably mounted on shaft 44, to be straddled by the tension handle bifurcations, as shown in FIG. 4.
  • ratchet gear 46 Carried immediately within the end of handle 20 and in contact with ratchet gear 46 is drive pawl 48; it is rotatably mounted to a pin 49 passing through both bifurcations of handle 20 and biased clockwise (in the sense of FIGS. L3 and 5) by spring 50.
  • a second shaft 52 is also provided within the strap feeding assembly 18, parallel to shaft 44 and passing through both sections 38 and 39 of the strap feeding assembly as well as the intervening portion 45 of the main frame 12, just below and inwardly of shaft 44.
  • Shaft 52 is journaled for rotation within the walls of strap feeding assembly 18 and passes through an enlarged opening (not shown) within main frame portion 12 to allow the shaft to move with assembly 18 relative to frame 12.
  • a tension gear 54 is secured to shaft 52 within drive section 38 and meshes with ratchet gear 46.
  • knurled strap feed wheel 56 Also rotatably secured to shaft 52 in section 39 of the strap feeding assembly is knurled strap feed wheel 56. It is located at a position'which is spaced from shaft 44 immediately above anvil portion upper surface 32 and wear plug 36, and in opposing relationship thereto.
  • Bias spring 42 in exerting a downward force upon the strap feeding assembly 18, serves to maintain feed wheel 56 normally against plug 36, and to compress the strap end S" therebetween. It should be noted that means other than wear plug 36 could be utilized as well; for example, a second wheel could be substituted, and strap end S" captured between such second roller and the feed roller.
  • a lift arm in the form of a lever 60 is pivotally secured by pin 61 within frame 12 spaced from shaft 44 immediately rearwardly of the end of assembly 18 opposite shaft 44, and below handle 20.
  • Lever 60 is comprised of two arms 62 and 64 of generally similar length of the order of small fraction of the, width of assembly 18 along frame 12. The two arms extend from pin 61 along frame 12, and define an angle somewhat greater than with respect to each other. Arm 62 extends back toward end 27 from pin 61, while arm 64 protrudes forwardly from pin 61 and into engagement with assembly 18 under a rearwardly extending end projection 66 (best seen in FIG.
  • Tension handle 20 is provided on its lower side near its pivoted end with an abutment or boss 68 positioned over arm 62.
  • the boss engages arm 62 when handle 20 is manipulated from its solid-line position of FIG. 2 to the dotted-line position, and when further moved downwardly to an extreme position immediately adjacent upper member 28 of frame 12, drives the arm 62 downwardly, as shown in FIG. 3.
  • arm 64 With such downward movement of arm 62, arm 64, already in engagement with protruding end portion 66 of assembly 18, drives portion 66 together with assembly 18 upwardly, pivoting assembly 18 about shaft 44.
  • a reaction tension is also present which tends to pull strap end S" toward seal 26 and to reverse wheel 56 and gear 54 contrary to the driven direction (as indicated by the dotted arrowed line in FIG. 5) between tensioning strokes.
  • a pair of holding pawls 72 and 74 (FIG. 5) are carried within drive section 38 of strap feeding assembly 18 and are positioned to engage tension gear 54 at spaced locations along its periphery.
  • Each holding pawl is biased by a coil spring (not shown) counterclockwise toward engagement with gear 54; however, the relatonship of the placement of the holding pawls with respect to the spacing of the gear teeth of gear 54 is such that only one of the holding pawls is in engagement between a pair of teeth of gear 54 at any one time, thereby minimizing the degree of reversal of the feed wheel under the influence of reaction tension.
  • the invention provides an extremely rapid one-handle operation of the tool, and it eliminates false starts due to accidental release of tension, since the loading means including lever 60 become automatically effectively inoperable with the tensioning of the strap.
  • a highly convenient, uncomp'licated, and very time-saving advance in tensioning tools is disclosed which does not sacrifice any of the advantages of prior tools.
  • tools according to the invention represent an advance in safety of operation as well, since sudden accidental loss of tension and the resultant violent movement of a partially tensioned strap is prevented.
  • a strap tensioning tool for use with a strap disposed around an article in a loop so that an inner strap portion is overlapped by an outer strap portion to complete said loop, with a seal receiving a section of said overlapped portions and with an end section of said inner overlapped portion folded under said seal held between the article and the facing seal surface, said tool comprising: a frame having an anvil section, said frame having an abutment at one end thereof engageable with said seal, said outer overlapping strap portion protruding beyond said seal; tensioning means carried upon said frame and including a movable handle, a
