Definitions

  • the invention relates to a transfer device for tapes, which is arranged to be movable between a decoiler and a tape processing or tape processing device, consisting of a pivotable guide table that can be inserted at one end into the gusset of the tape beginning and the collar, and a pair of clamping elements, in particular formed by rollers, of which a clamping element is arranged at the other end of the control table and essentially in the guide plane of the control table.
  • Transfer devices of this type are known in various designs (DD-PS 33 557; DD-PS 27 545).
  • a pressure roller is assigned to the federal government, which presses against the outer layer of the federal government and in this way prevents the federal government from springing open.
  • the transfer device is for moving the transfer device between the reel and the downstream strip processing or processing device arranged on a swivel arm in such a way that the transfer table can be swiveled under the beginning of the belt of the belt to be pulled off from above. With such a device it is only possible to detect a beginning of the tape that is in the upper region of the federal government. In practice, however, there is also the requirement to record the beginning of the strip at the bottom of the bundle and to feed downstream strip processing or strip processing equipment.
  • the invention has for its object to provide a transfer device of the type mentioned, which can be used both for the top of the collar and for the bottom of the band beginning of the band.
  • the guide table has a guide plane for the belt on both its top and bottom and that the clamping elements are mutually adjustable such that their passage gap is either in the upper or lower guide plane of the guide table.
  • the transfer device according to the invention in comparison to known transfer devices, only an insignificant additional effort is required in order to be able to detect a tape start both on the top and on the bottom of the collar and to transfer it to the downstream tape processing or processing device.
  • the guide table only needs to be designed in such a way that it can guide the belt not only on one side but on both sides, while the clamping elements, in particular clamping rollers, have to be convertible to the two guide levels.
  • the convertibility of the two clamping elements can be implemented constructively in various ways.
  • the clamping elements can be pivoted relative to the guide table by means of swinging.
  • one or the other clamping element lies in the level of the guide table, while the second clamping element then has the task of pressing it against the clamping element lying in the guide level of the control table after inserting the beginning of the tape.
  • both clamping elements are mounted on rockers.
  • only the clamping element lying outside the guide plane can be pivoted relative to the guide table by means of a rocker and one of the two clamping elements can be telescoped.
  • the telescoping ability of one of the two clamping elements is necessary so that the clamping element mounted on the rocker can pass through the clamping element remaining in the guide plane.
  • a pressure roller acts on them at least as long as the beginning of the tape has not yet been gripped by the transfer device.
  • This pressure roller is preferably arranged in the region of the upper vertex of the collar. It then also holds the beginning of the tape in a position in which it can be easily gripped by a transfer device.
  • the beginning of the band is to be recorded below the federal government, it is necessary to provide aids for guiding the beginning of the band on the federal government. According to one embodiment of the invention, this can be achieved in that the pressure roller is carried by the movable transfer device.
  • a coil 2 made of metal strip is arranged on a decoiler 1.
  • the metal strip 3 is processed in a processing device 4, e.g. a straightener, processed.
  • a pair of drive rollers 5, which can be clamped in place is provided at the entrance of the straightening apparatus. So that the belt 3 runs horizontally into the straightening apparatus 5 in the processing plane, which is arranged horizontally here, regardless of the point 6 which changes in height during operation, a height-adjustable deflection roller 8 is arranged in a frame 7.
  • a transfer device 9 is arranged on a carriage 10 between the reel 1 and the strip processing device 4 as well as the straightening apparatus 5 and the deflection roller 8.
  • the carriage 10 can be moved on a rail 11 by means of a hydraulic drive 12.
  • the transfer device 9 has a transfer table 13 with an upper guide level 13a and a lower guide level 13b.
  • the guide levels 13a, 13b are formed by smooth table surfaces.
  • the table 13 has a front wedge-shaped end 13c.
  • a roller 14 is provided, which forms a clamping element. This roll is telescopic in the table.
  • a second roller 15 cooperates with this roller 14 and forms the second clamping element.
  • This roller 15 is carried by a rocker 16 which can be pivoted in the carriage 10. Both the transfer table 13 and the rocker 16 can be pivoted independently of one another by means of hydraulic devices not shown in the drawing.
  • the transfer device works in the following way:
  • the carriage 10 is then moved in the direction of the tape processing device 4 until the tip of the tape start comes to rest in the area of the drive roller pair 5. So that the tape can be pulled off, at least one of the rollers 14, 15 is equipped with a backstop.
  • the drive roller pair 5 is moved together and detects the tip of the beginning of the tape.
  • the rollers 14, 15 are opened and the carriage 10 is moved back into the position shown in FIG. 3.
  • the deflection roller 8 is moved against the belt 3 so that it runs horizontally into the drive roller pair 5.
  • the roller 14 arranged telescopically on the guide table 13 is retracted so that the other roller 15 can be pivoted downward.
  • the roller 15 can also be telescopic, which in this case is extended for the pivoting.
  • the roller 14, like the roller 15, it is also possible for the roller 14, like the roller 15, to be arranged on a rocker arm, so that in this case it can be pivoted downward out of the guide plane of the guide table 13 and the roller 15 is pivoted into the position of the roller 14 becomes.
  • a roller 21 which can be pressed against the collar is provided on the carriage 10.
  • the deflection roller 8 is arranged on the underside of the belt 3 because of the lower-lying drain point. Otherwise, the functional sequence is the same as in the exemplary embodiment in FIGS. 1 to 3.
