Definitions

  • the invention relates to a tool for binding a ribbon around an object, especially a wire harness, the one Tensioning device for the tough elastic, rigid band contains.
  • the tensioning device comprises a toothed tensioning roller and a the tape on the opposite of the tension roller Side support roller abutment.
  • the tension pulley is during of the clamping process constantly driven and rotating continues even if a predetermined one is reached Tension the tape stands still and is cut off.
  • the invention is based, with such an object Tool as mentioned in the preamble of claim 1 to improve the reproducibility of the belt tension and her To prevent slackening during the tensioning process.
  • the abutment is formed by at least two support rollers, which are arranged one behind the other on the circumference of the tensioning roller and are pressed against the tension pulley by spring force. She cause the tape not only in the points of contact of the Support rollers is pressed against the tension roller, but due to its bending resistance throughout the section between.
  • the tension pulley is therefore not only quasi punctiform, but over an extended one, from the support rollers limited distance together with the band. This has the consequence that the pressure force, i.e. the force with which the tape per unit length pressed against the circumference of the tension pulley is lowered, and consequently the teeth of the Tension roller not or hardly at all when the belt is at a standstill intervene in the strip material.
  • the ratio between that at the support rollers pressure force and in the area between the support rollers acting pressure force may not be constant. It is sufficient in these cases, if the arrangement is made such that there is a setting within the setting range is where the unit of length between the tape and the Extent of the tensioning roller acting force on the support rollers approximately is as big as between them. You choose the arrangement expediently so that when setting a low Band tension is the force per unit length between the band and the circumference of the tensioning roller acts on the support rollers is less than between them. You can with the Support rollers even go to zero.
  • Their angular distance in relation to the tensioning roller is preferably 30-70 °, more preferably 40-60 °. It can also a larger number of support rollers can be provided.
  • the tension with which the tape between the support rollers on The circumference of the tension pulley depends on the diameter the tensioning roller and the angular distance of the support rollers. The smaller these dimensions are, the larger it is. To the others this force depends on the resistance the tape has opposed to its corresponding bend. This is again depending on the elastic modulus of the strip material and the Moment of inertia of the belt cross section. It is easy to do this To vary parameters in such a way based on experiments that the desired pressure force is reached.
  • the reproducibility of the belt tension also depends on the Tooth shape. It has proven to be useful if the leading flank of the teeth in the direction from the tooth flow to the Tooth tip inclined backwards in the direction of rotation of the tension pulley is. This ensures that the teeth are less likely to cut or chop into the tape material, but to slide over it. The abrasion is corresponding less.
  • the flank angle of the teeth is expediently between 10 ° and 45 ° to the band normal, more preferably between 18 ° and 30 °. Nonetheless, should the teeth are pointed in cross section.
  • the invention When using tapes that are smooth and smooth on one side are serrated on the other hand, the invention performs independently of good results whether the teeth of the tension pulley interact with the smooth or serrated side of the belt. However, interaction with the toothed is preferred Page.
  • the front part of a so-called cable tie tool is shown, whose tool body 1 on his forehead one of the parts 2 and 3 formed wrap, which a bundle of cables 4 receives as an object to be bound to to loop around the cable strap 5.
  • This points at its end a lock 6, through the opening of the free end 7 of Cable tape is guided and contains a pawl that cooperating with a serration of the cable band its return movement prevented by the lock.
  • the cable tie around the cable harness 4 is looped, there is the lock 6 in a lock holder of the lock, not shown predetermined position of the same.
  • the free end 7 through the lock is passed through, it goes straight into the Clamping device 8, which detects it and around the wiring harness 4 tightens. Does the cable tie have sufficient tension reached, the part protruding from the lock 6 is through cut off a device indicated by an arrow at 9, and the tied wire harness can the pliers 2, 3 be removed.
  • the tensioning device 8 consists of a tensioning roller 10 which stored in a fixed position in the tool body 1 and in the direction of the arrow can be driven in rotation, and two support rollers 11 which the band end to be grasped and exciting 7 against the Press tension roller 10.
  • the support rollers 11 are on one Swing arm 12 mounted around a fixed in the tool body 1
  • Axis 13 is pivotable and counterclockwise by a spring 14 is acted upon.
  • the force of the spring can be achieved by means of an adjusting screw 15 can be changed.
  • a stop 17 gives the distance of the support rollers 11 from the circumference of the tension roller 10 before if there is no band 7 in between. The distance is set so that the thinner, free Belt end between the tension roller 10 and the one initially reached Support roller 11 can be detected. It is less than that Band in its part following the thinner tip.
  • the tension roller 10 is provided with teeth, which are preferably are sharp-edged.
  • the diameter of the tension roller 10 is expediently a multiple of the strip thickness. Preferably it’s three to ten times bigger.
  • the diameter of the support rollers 11 is of the same order of magnitude as that of Tension pulley 10.
  • the tape material is expediently more elastic Plastic, especially polyamide.
  • the tape lies on the toothed circumference of the tension roller 10 the sheet (19) determined by the support rollers 11.
  • the Extent of its bend and its resistance to this bend Rigidity determine the strength of the system in the middle area this route.
  • the force (arrow 18) with which the Support rollers 11 are pressed against the belt is determined by adjusting the spring 14.
  • the spring force can be the force with which the tape is in the immediate vicinity Support area of the support rollers 11 against the surface the tension pulley is pressed, be less than the force in the middle of the investment route; this applies to high spring force Opposite.
  • the tape will be attached to the Tensioner roller 10 over a considerable distance under simultaneous Engagement of several idler teeth instead.
  • the tensioning device After the introduction to the The tensioning device is initially conveyed from the tensioning roller without slippage. If it tightly surrounds the item to be bound, His tension grows steeply until it finally becomes that big will that the friction force applied by the tensioning roller 10 equal. At this moment the tape stops while the tensioning roller 10 continues to run through its on the Belt surface exerted friction force maintains the tension.
  • the band tension at which this condition occurs is depending on the setting of the spring 14. Using the adjusting screw 15 can therefore be the belt tension to be achieved can be set.
  • the Cutting device 9 switched on.
  • the drive of the tension pulley 10 can then be ended as soon as the cut Tape end 7 is ejected.
  • the time at which the cut takes place is set so that just the number of revolutions of the Tensioner 10 could take place for the passage of the Longest possible cable ties with the smallest possible cable harness diameter necessary is. Unnecessarily long rubbing and Wear of the tensioning roller 10 is thereby avoided.
  • a guide bar 16 may be provided during the insertion process the belt tip from the nip at the first Tension roller 11 to the nip on the second tension roller 11 directs.
  • the diameter was the tension pulley (measured up to the tooth tips) 8 mm.
  • the The diameter of the support rollers was 7 mm.
  • the angular distance the support rollers, based on the axis of the Tension pulley was about 53 °.
  • the scope of the tension pulley was provided with 20 sharp-edged teeth, their flank angles compared to the radius was 23 °. It became a polyamide tape with a thickness (including serration) of 1.15 mm and one Width of 2.6 mm processed.
  • the toothed side of the Band was turned to the tension pulley.
  • the band tension was about 80N. On that one Place the belt where the tensioning roller is opposite the belt slipped, the teeth of the band were over one Line of slightly more than 4 mm in length is squeezed evenly and rubbed off. At the ends of this route where the support rollers had worked, the deformation was little greater than in the middle of this route.
