Definitions

  • the invention relates to the use of a device according to the preamble of claim 1.
  • Devices of the generic type are known from DE-A-1 250 395. They serve to bend the beginning of the band wound on a spool in such a way that the naturally existing curvature is counteracted, so that a comparatively flat band which can be fed into the downstream straightening or machine tool is produced.
  • the use happens in such a way that the free end of the coil is placed on the feed surface, it swings upwards via corresponding hydraulic actuations and is brought into a position parallel to the stop surface above it, so that the end of the coil is now in between.
  • the final threading into the machine then follows with the appropriate feed.
  • the threading device which essentially consists of two surfaces, can be regarded as disadvantageous in several respects. It is attached directly to the respective machine, has an unfavorable transmission torque due to the fact that it lies almost vertically on the feed surface, at least at the beginning of the threading process, and therefore requires an appropriately complex dimensioning and design of the forces to be applied.
  • the invention has set itself the task of creating a threading device, by means of which band-shaped material can be introduced into several machines which work independently of one another.
  • the basic idea of the invention is now to use and use the device of the generic type as a threading device, that is, to use it for threading strip-shaped material unwound from a coil (coil) into a straightening or machine tool, by setting it up to the side of the coil and the Arm is extended until the gripping roller engages behind the band-shaped material which is clamped between the two gripping rollers when the arm is retracted, and is brought into the desired position by pivoting and is threaded in by feeding.
  • the core of the device according to the invention are two axially parallel gripping rollers which can be moved relative to one another. With their help, the free end of the band-shaped material is grasped by the fact that a gripping roller rests on opposite sides of the material and is pressed onto one another. The end of the band is brought into the position suitable for threading in that the two gripping rollers are pivoted by a corresponding angle with the band-shaped material fixed between them. The material is inserted into the machine by feeding the belt. In a manner known per se, the coil is on a decoiler and is fixed by a hold-down device.
  • the procedure is as follows: The threading device is set up to the side of the coil, more precisely next to the desired and future web of the band-shaped material in the area of the coil, and then the arm is extended so far that the gripping roller located behind it engages behind the band. In the next step of retracting the arm, the band is then clamped between the two rollers and held in place while maintaining the possibility of translational displacement. By pivoting through the desired angle, it is possible to bring the free end of the band into the desired position. The threading then takes place by appropriate feed.
  • the proposed threading device is not directly attached to the straightening or machine tool, so that it ends the threading process can be removed and used for another machine.
  • the design can therefore be chosen to be comparatively small in an advantageous manner.
  • Another advantage can be seen in the fact that the angle of the pivoting is arbitrary, so that the free end of the band-shaped material can be moved in any direction and end position. Therefore, in addition to the generally prevailing horizontal feed, other end positions are conceivable and reachable.
  • a key advantage is the free maneuverability in the room, which allows the tape to be picked up on spools of different diameters and at any point on the circumference and to be entered in any position or distance of the entry opening of the straightening or machine tool.
  • the gripping rollers can only grip the band on the edge, although of course it is also conceivable and possible to set the entire width.
  • the threading device 1 shown in FIG. 2 consists of an arm 2, on the outer end of which a gripping roller 3 is attached.
  • the arm 2 can be displaced in the plane of the drawing in accordance with the direction of the arrow, as a result of which the position of the gripping roller 3 can be changed.
  • the position shown in solid lines represents the moment at which the gripping roller 3 rests on the band-shaped material 4 and engages behind it.
  • On the side opposite the gripping roller 3 there is a further gripping roller 5.
  • the two gripping rollers 3, 5 are pressed against the band-shaped material 4 from both sides and are thereby fixed.
  • Both the gripping roller 5 and arm 2 with the gripping roller 3 attached to it can be moved together about the pivot axis 6.
  • the end of the band-shaped material 4 in approximately horizontally and can be introduced by appropriate feed into the input slot 7 of the machine 8 used for processing. The threading process is thus ended, so that the threading device 1 can be used elsewhere.
  • the Co 9 consisting of the wound strip-like material 4 is located on a decoiler 10. It is set up in relation to the threading device 1 in such a way that the strip-shaped material 4 is fed past and straight to the machine 8. On the top there is the hold-down device 11, whose task is to prevent the coil 9 from loosening beyond the free end.
  • a threading device 1 is also shown in side view.
  • the arm 2 and the gripping roller 3 attached to the outer end can be clearly seen. Its displacement takes place via a cylinder 12.
  • the extended state is also shown here in dotted lines.
  • the gripping roller 3 opposite is the gripping roller 5 on a boom 13, to which the arm 2 is also attached.
  • both gripping rollers 3, 5 and, if present, the free end of the band-shaped material 4 clamped in between can be moved and brought into the desired position at the same time.
  • the parts of the threading device 1 just described are essential for the invention and are therefore shown enlarged in comparison to the foot 14.
  • the invention makes one of several Machines that can be used independently of one another are proposed with favorable transmission torques.
