Definitions

  • the invention relates to a band for tensioning elongated objects and a tool for looping and tensioning the band around an object.
  • the band comprises a band tongue and a band lock, which has an opening for receiving the band tongue.
  • the tool has a wrapping guide that can be closed around the object for the ready-to-use band with a holder for the band lock, a guide that is approximately aligned with the holder for the free end of the band tongue, and a device for generating a relative movement between the holder that pushes the free end of the band into the opening and leadership.
  • the invention has for its object to provide a tool-belt combination of the type mentioned, which is free from such problems.
  • the band tongue has a central recess and the device for generating the relative movement has a feed finger which interacts with the recess.
  • the feed finger to cooperate with the band, in which essentially only forces acting on the band in the common plane of the band center axis and the feed finger center axis are exerted, which do not influence the relative position of the free band end to the lock opening.
  • the guide for the free end of the tape is straight and the feed finger and the guide for the free end of the tape are designed so that the forces exerted on the free end of the tape by the feed finger run exclusively in the direction of the tape.
  • the start section and the end section of the loop guide are arranged transversely to one another.
  • the two band sections adjacent to the lock during tensioning must also run transversely to one another. This is disadvantageous when reclamping objects which are round in cross section, for example cable harnesses, because the band cannot adapt to the outline of the object and may therefore remain loose.
  • the leading end of the belt closes the lock after the belt is around the object has been looped can assume the correct, approximately rectangular starting position for the insertion of the leading end of the band into the lock and that, on the other hand, the object can approach the lock unhindered during the tensioning of the band.
  • the band can therefore also be stretched around, for example, circularly delimited objects without the risk of later loosening.
  • different drive means are provided for the escape flap and the feed finger, so that the different movement characteristics of these parts can be taken into account.
  • the peculiarity of the feed movement is that it must take place quickly and vigorously over a considerable distance. While it may be expedient to derive the movement of the other components from cam disks which only carry out a common rotation for each working cycle of the tool, it would be problematic to likewise derive the feed movement directly from such a cam disk.
  • a spring is therefore provided for driving the feed element, which is tensioned again in a period of the working cycle of the tool that is outside the feed. By relaxing the spring, the desired rapid development of force can be achieved over a considerable distance, while the tensioning of the spring can be carried out over a longer period of time, so to speak, during other periods of the working cycle.
  • the an object 1, for example a harness, to be wrapped around cable strap 2 consists of a strip tongue 3 and a lock 4 which is connected in one piece to the rear end of the strip tongue 3 and which contains a pawl 5 which interacts with the toothing 6 of the strip when it does so the opening 7 of the lock 4 is inserted.
  • the band known so far has near its front end 8 a central cutout 9 which - as explained further below - serves for the engagement of a feed finger.
  • the tool for wrapping the band 2 around an object 1 and for tensioning and cutting the band has a tool body, which is not shown in the drawing. It contains a feed channel 10, in which the tape can be advanced with a tongue out of a magazine in order to emerge from the outlet opening 11 of this channel at the front of the tool body.
  • the looping guide is arranged, which is formed from three flaps 12, 13, 14, which in the closed state (FIGS. 2 and 4) contain a continuous guide groove 15, which in an initial section 16 is aligned with the channel 10 and the outlet opening 11 connects and after turning through 270 ° in an end section 17 returns in the vicinity of the outlet opening 11.
  • a lock holder 20 is provided for the lock 4.
  • the end portion 17 of the guide groove forms the guide for the free band end and leads this to the lock holder 20, in such a way that the leading end 8 of the band 2 is aimed at the opening 7 of the lock 4.
  • the flaps 12, 13, 14 of the looping guide can assume an open position, which is shown in FIG. 5, in order to enter the object 1 to be bound or to let the bound object emerge.
  • the flaps 13, 14 are connected to drive means which each consist of a control rod 22, 23, a cam lever 24 or 25 and a cam disk 26 or 27 and are supplemented by suitable springs (as 28 in FIG. 5) can.
  • drive means which are each shown separately in one of the figures, although they lie next to one another and the associated cam disks 26, 27 are firmly seated on a common shaft, which performs one revolution per work cycle.
  • the loop guide 12, 13, 14 has a certain, unchangeable circumferential length, which corresponds approximately to the length of the band 2.
  • the leading end 8 of the band is in front of the lock 4.
  • An additional relative movement is therefore required, through which the band end 8 is inserted into the lock 4.
  • This is the purpose of the feed finger 30 which, in the position according to FIG. 2, projects into the guide groove 15 at the point at which the opening 9 is located in the band.
  • the leading section 8 of the tape slides over it when it is inserted into the guide groove 15 until the opening 9 comes into which the feed finger 30 enters so that the tape becomes itself under its elastic force also in the
  • the feed finger 30 adjoins the peripheral surface of the guide groove 15.
  • the elastic force arises from the fact that the band is straight in the original state or has a larger radius of curvature than the band guide 15 of the looping guide and has elastic properties by being made of tough-elastic plastic.
  • the feed finger 30 is seated on a sliding body 31 which is contained in a sliding bore 32 parallel to the end section 17 of the guide groove 15 and which can move at least between the end positions shown in FIG. 2 on the one hand and FIG. 5 on the other hand, the feed finger 30 moving in one Slit 33 moves, which extends between the sliding bore 32 and the guide groove 15 (Fig. 3).
  • the sliding body 31 is acted upon by a spring 35, which tries to transfer it from the initial position according to FIG. 2 to the end position according to FIGS. 4 and 5.
  • a spring 35 which is anchored on the one hand to the sliding body 31 and on the other hand to a cam lever 37 (FIG. 4), the position of which is determined by a cam disk 38 rotating in the direction of the arrow, which is fixed on the same shaft as the cam disks 26 and 27.
  • the feed rollers 41 now tension the belt 2 (Fig. 5). At least the flap 14 in FIG. 5 moves to the right and thereby evades the object 1, which is pushed into a position above the lock bracket 20 by the tape tension.
  • the flap 14 is therefore referred to as an escape flap. Your entire movement can be positively controlled. However, it is also possible to forcibly hold on to only its first position during the wrapping process, while it is only released when the band is tensioned, in order to be able to give in to the pressure of the displaced object 1 freely or against spring force.
  • the flaps 12, 13 of the looping guide open during the tensioning process in order to release the tied object 1 after the tensioning process has ended.
  • a blade 44 (FIG. 5) cuts off the protruding band end, and the bound object 1 can be removed from the tool.
  • the spring 35 is then tensioned again for the next working cycle by the cam follower 40 engaging with the slowly rising ramp 45 of the cam 39.
  • the central arrangement of the feed finger 30 and the band opening 9 and the straight, parallel arrangement of the guide groove 17 and the guide 32 of the feed finger ensures that, despite the rapid movement of the feed finger, no forces are exerted on the free end of the band which cause it to shift laterally could lead to the lock opening 7.
