Definitions

  • feed devices are known in which the two feed pliers are arranged next to one another transversely to the belt.
  • the feed paths of these devices overlap or are parallel to each other.
  • the tapes are only recorded on one side.
  • the feed tongs are driven by a pneumatic or hydraulic linear drive with a constant stroke, i.e. caused by one or more working cylinders, the linear movement by converting into two rectified rotary movements on the crank drives cause a sinusoidal course of the speed of the feed tongs over their forward and return.
  • this tong feeder is practically doubled, i.e. the same lifting capacity is produced; the same lifting capacity is achieved with less than half the drive capacity of the devices mentioned at the beginning.
  • the shaft of the adjusting means end in a bevel gear, which engages in two further bevel gears, which are arranged perpendicular to the axis of the shaft of the adjusting means and are provided with threaded spindles, and each of the two threaded spindles engages in a sliding piece, which is guided in a crank disk in a sliding groove and carries the crank pivot bearing for the crank arm.
  • each support slide is guided on a guide track carrying two parallel planes via a plurality of support rollers engaging on both sides, and the slide pivot bearing is designed around an axis leading through the center of gravity of the slide.
