Definitions

  • the invention relates to an arrangement for tying an object, for example a cable harness according to the preamble of claim 1, by means of a band consisting of a band which has a band tongue and a band lock with a band opening which receives and holds the free end of the band tongue, and a tool.
  • the tool comprises a lock holder for receiving the band lock during the binding process and a looping guide which starts from and returns to the lock holder and can be opened and closed for guiding the band around the object to be bound.
  • the tool also includes a slider for conveying the tape into a position in which the tape tongue is in the loop guide and the lock is in the lock bracket.
  • Such an arrangement is e.g. B. from FR-A-2401742 known.
  • the invention simplifies this arrangement in that the lock holder is at least partially formed by the slide.
  • the slide reaches its end position without the need for special control and drive means.
  • the head of the slide is given a shape which is suitably adapted to its function as part of the lock holder.
  • the slide or the head of the slide forming the mounting part is guided in a guide which defines its position in the lock mounting.
  • the position of the slide head in the lock holder is therefore determined on the one hand by the guide, the guide surfaces of which run parallel to the slide movement direction, and on the other hand by a force which holds the slide head in the holder position. It can simply be the feed force that previously pushed the slide into the holding position. However, separate organs can also be provided for this.
  • the band lock is supported on the opposite side of the slide by a stop involved there in the formation of the lock holder.
  • This expediently comprises a spur which is located such that its tip lies between the end of the band tongue connected to the lock and the area into which the leading end of the band tongue emerges from the band opening.
  • the spur is after the end of the tensioning process between the origin and the protruding end of the strap and can therefore solve the problem Disable the lock from the bracket if the release movement is transverse to the direction of the hinge.
  • the spur and / or other parts of the holder which engage in front of a projection of the lock or in front of the band, can be pivoted away after the binding process, expediently in the direction in which the lock should be removed from the bracket.
  • the spur or these other parts of the holder which engage in front of a projection of the lock or in front of the band emerging from the lock, are rigidly connected to a pivotable part of the looping guide, the pivot point being arranged in such a way that the spur or these parts is moved approximately in the direction in which the lock is to be removed from the lock holder when the wrapping guide is opened.
  • the spur or these parts are not only removed from the position in which they would hinder the removal of the lock from the tool, but they also perform a kind of ejector movement, through which the lock with the band and the bound object from the binding position is removed and can therefore be removed even more easily.
  • the spur can also be part of a cutting device intended for cutting the projecting end of the band or can carry such an element.
  • the free end of the strap tongue needs a guide to get into the correct position for insertion into the strap opening of the lock.
  • at least part of this guide can be formed on the slide.
  • the end of the loop guide can be at a relatively large distance from the lock in its end position, which allows the guide for conveying the band into the binding position and for guiding the slide into the holder position very close to the circumference of the free space, which is provided within the loop guide for receiving the object to be bound.
  • the circumferential contour can also be approximated to the circular shape.
  • the tool has a tool body 1 and a handle 2, on which it can be held. Between the walls 3 and 4 of the housing body 1 there is a guide channel 5 for a band 6 made of tough elastic plastic such as polyamide. It reaches the position within the channel 5 shown in FIG. 1 in any way, for example by automatic means (not shown) from a tape magazine or by hand.
  • the band has a band tongue 7 and a head 8, the tip of the band tongue pointing to the front end of the tool body shown on the left in FIG. 1, while the head 8 is located at the rear.
  • a slide head 9 behind the lock 8 the end face of which cooperates with the lock 8 is adapted to the shape of the lock 8 and is fastened to the front end of a flexible steel strip 10 which is wound on a roller 11.
  • the head 9 and the steel band 10 together form a slide for pushing the band 6 from the position shown in FIG. 1 to the position (FIG. 3) in which the band is used to bind an object.
  • the edges 12 of the steel strip 10 project laterally beyond the slide head 9 (FIG. 5) and are slidably received by grooves 13 in the side walls of the guide channel 5. Furthermore, the profile of the guide channel 5 can (but does not have to) be adapted to the profile of the band lock 8 in order to give it hold on its way into the binding position transversely to the feed direction.
  • the tool has pliers formed by parts 15 and 16. It forms a guide for the band 6 during its path wrapping around the object to be bound.
  • Pliers part 15 is pivotable about the axis 17;
  • Pliers part 16 is pivotable about the axis 18.
  • Drive and control means are provided which provide for the pivoting of the pliers parts from the open position shown in FIG. 1 to further functional positions, as described below. These drive and control means are conventional and therefore not shown and explained.
  • the tongs pick up an object to be bound, which can be, for example, a bundle of cables 19 (FIG. 2) which are to be firmly bound together by means of the band 6, as is the case here is shown in the final stage in Fig.1.
  • the band tongue 7 surrounds the cable bundle 19 under tension.
  • the free end of the band tongue 7 is guided through the lock 8 and fastened therein.
  • the protruding end of the tongue is cut off.
  • the pliers parts 15 and 16 can be brought into a closed looping position according to FIG. They contain a guide groove 20, the width of which corresponds approximately to that of the band tongue 7 and the depth of which is considerably greater than the thickness of the band tongue 7.
  • the guide groove 20 is delimited at its beginning by a spur 21 which is firmly connected to the pliers part 16. If the tip of the band tongue 7 is inserted into the beginning of the guide groove 21, which is accomplished by means of no interest here (see simultaneously filed European patent application EP-A-0 596 363), its further path through this groove around the object to be bound 19 determined around, which ends at 22 at the inner end of the pliers part 15.
  • the lock 8 has also reached its end position, which is determined by part of the lock holder.
  • This consists of a housing-fixed mounting part 23, whose surface facing the lock 24 is at least partially adapted to the shape of the lock.
  • This also includes the already mentioned spur 21 and the area 35 behind the spur 21, which is cut out in the drawing plane for the passage of the band but can form stop surfaces for the lock on the side thereof (above and below the drawing plane).
  • the spur 21 and the part 35 together with the mounting part 23 fixed to the housing form a stop which is adapted to the shape of the lock 8 so that its position in the mounting is clearly determined, provided that the lock 8 is pressed against these mounting parts.
  • the slide head 9 which is designed as a third mounting part. Due to a continuous feed force exerted on the steel strip 10, which can be determined, for example, by a slip clutch or spring in the drive of the roller 11, the slide head 9 presses the lock 8 against the holding parts 21, 23 and thereby exactly determines the end position of the lock.
  • the spur 21 grips between the band tongue 7, where it is integrally connected to the lock 8, and the area into which the leading end of the band tongue 7 emerges from the band opening 25. This means that the tip of the band must pass behind the spur during the wrapping movement (Fig. 2) on the front, but in the final state.
  • the spur itself lies between these two band areas as a stop on the lock body and is therefore involved in its positioning. This arrangement of the spur on the lock body is not absolutely necessary. It is only necessary that the holder parts 21, 23, 9 cooperate with the surface of the lock body in such a way that its position is clearly defined.
  • the lock is shaped so that the tape takes its origin approximately in the feed direction from the lock and that the Band opening 25 is approximately parallel to this direction. Exact parallelism is not necessary. Rather, when looking at FIG. 3, the band opening could also be rotated a little counterclockwise with respect to the direction shown.
  • the free end of the tongue is located approximately at the end 22 of the loop guide or between this end and the band lock 8.
  • the band tip is preferably close to the lock 8.
  • the band tip must now be inserted into the band opening 25 of the lock. This is done (FIG. 3) in that the tong part 15 is pivoted further in the arrow direction 26 from the wrap position shown in FIG. This shortens the distance available in the pliers part 15 for receiving the band tongue 7. Since the lock 8 is meanwhile held in the lock holder 21, 23, 35, 9, the band tongue 7 slides in the pliers part 15 and the band tip 27 inevitably moves further downwards in FIG. 3.
  • the pliers part 15 has reached its end position shown in FIG. 4
  • the free end of the band tongue 7 has passed through the band opening 25 and has reached the gap between two tensioning rollers 28, 29 rotating in the direction of the arrow, which grip and tension the band end.
  • the tensioning process is continued until the desired tension in the band tongue 7 is reached and the object to be bound (cable 19) is tightly tied.
  • a blade 31 is provided which is guided in its longitudinal direction and is connected to conventional drive and control means, not shown. To make the cut, move it to the left in Fig. 4 moved so that its cutting edge cuts the tongue.
  • the spur 21 serves as an abutment. It can be sufficient for the spur to form a smooth contact surface for the belt in its abutment area, as shown. Instead, can at this point, however, a depression can also be provided in the surface of the spur, which forms a counter-cutting edge or cutting edge which interacts with the blade.
  • the distance between the end 22 of the loop guide and your lock 8 is relatively large. This can be attributed to the fact that the lock holder is arranged directly on the circumference of the binding cross section. Consequently, in the distance between the end 22 of the loop guide and the lock holder, the feed path of the band from the guide channel 5 on the one hand and the path of the band from the loop guide 20 on the other hand intersect at an acute angle. This great distance can be avoided by leading the two paths at right angles to one another (EP-A-0 264 142), but then has to accept other, greater disadvantages.
  • the guide uncertainty in the distance between the end 22 of the loop guide 20 and the band opening 25 in the lock 8 eliminates the invention in that it provides the slide head 9 with a guide surface for the band tip.
  • the slide head 9 has a surface 32 facing the open side of the tool, which opens at the band opening 25 of the lock 8 and along which the tip 27 of the band can slide to find the opening.
  • the guide surface 32 can be designed in the shape of a groove in order to also give the band tip 27 a lateral guide; However, this is generally not necessary.
  • the slide 9, 10 can be pulled back into its starting position (FIG. 1) and the bound object can be removed.
  • the lock 8 shown in the drawing has a fastening part 33, which comprises a plate 34 which projects on all sides. This plate lies behind the spur 21 and partly behind the mounting area 35.
  • these parts 21, 35 are firmly connected to the lower pliers part 16, they become forward and open during the opening movement of the pliers part in the opening representation shown in FIG also pivoted down a little.
