Definitions

  • the invention relates to a folding blade drive for a folding machine according to the preamble of patent claim 1.
  • the folding blade drive comprises a deflection rollers 7 circulating drive belt 6, to which a folding blade 1 is attached adjacent to its ends.
  • the folding blade 1 is guided linearly for a vertical lifting movement.
  • the drive belt 6 is driven by a linear motor 3, which has a running in a linear motor stator 4 linear motor rotor 5, which is connected to the drive belt 6.
  • a movement of the linear motor rotor 5 is transmitted to the two ends of the folding blade 1 so that a uniform movement of the folding blade 1 takes place.
  • the invention has for its object to provide with simple design means a height adjustment for the generic Falzhetantrieb.
  • the linear drive is formed by a piston drive, for example a pneumatic drive, which has a piston running in a cylinder, which is mounted in an intermediate region of a piston rod forming the lifting element.
  • the drive element is fastened with both ends to a fastening element whose position relative to the piston rod in the longitudinal direction is adjustable.
  • a threaded bore running in the longitudinal direction of the piston rod is preferably formed into which a threaded bolt secured against rotation engages with one end, one end of the drive element being fastened to both ends of the threaded bolt.
  • a rotary adjusting device connected to a drive is provided for adjusting the rotational position of the piston rod.
  • the drive can be started by a central control.
  • an oblique adjustment of the folding blade can be achieved in that the folding blade is pivotally mounted at one point on the drive element and the position of another location, is attached to the folding blade on the drive element, with respect to the drive element adjustable.
  • the other point of the folding blade is preferably hinged to an eccentric, which is pivotable about a pivot axis fixed relative to the drive element.
  • Fig. 2 shown Falzhetantrieb 10 has as in Fig. 1 shown known Falzhetantrieb a guided in the vertical direction folding blade 12 which is attached at its longitudinal ends to a drive belt 14, the plurality of deflection rollers 16 rotates so that the folding blade 12 performs a uniform stroke movement during movement of the drive belt 14.
  • a linear drive is provided which is formed by a pneumatic piston device 18.
  • the pneumatic piston device 18 comprises a two-part frame-fixed cylinder 20, in which a piston 22 is guided substantially parallel to the longitudinal direction of the folding blade 12.
  • the piston 22 is fixed in an intermediate region of a piston rod 24 passing through the cylinder 20.
  • a piston rod 24 surrounding the piston spring 26 is arranged, which is supported with one end against the piston 22 and with its other end against the piston head 25 and a left-directed force on the piston 22 exerts.
  • a knurled nut 40 is fixed so that upon rotation of the knurled nut 40, the piston rod 24 can be rotated about its longitudinal axis. Since the threaded bolt 32 can not rotate about its longitudinal axis and is in threaded engagement with the piston rod 24, the threaded bolt 32 is moved with a rotation of the knurled nut 40 in the direction of the piston rod 24 or away. As a result, an adjustment of the attachment of the ends of the drive belt 14 in the longitudinal direction of the piston rod 24 and thus an adjustment of the height of the folding blade 12 is possible.
  • the linear drive can also be formed by a solenoid drive or a linear motor with a translator.
  • a possibility is shown to adjust the inclination of the folding blade 12 with respect to an arc.
  • the folding blade 12 at the in Fig. 3 left ends of the folding blade 12 is provided an upwardly extending plate-shaped projection which is clamped between two clamping plates 44, 46. Through the clamping plates 44, 46 and the projection passes through an axis 48. As a result, a pivotal mounting of the folding blade 12 is formed about the axis 48.
  • the other end of the folding blade 12 is hinged to an eccentric 50 which rotates about an off-center axis 52 which passes through a clamping plate 54.
  • the folding blade is about the axis of rotation 48 of in Fig. 3 tilted left suspension.
  • the clamping plates 54 and the drive element clamped thereon remain stationary during the rotation of the eccentric 50.
  • a threaded bore 56 is formed in the side surface of the clamping plate 54, in which a spigot thread 58 of a pivot pin 60 engages, which has a portion 62 of larger diameter, which bears against the outer surface of the clamping plate 54.
  • On the portion 62 of the eccentric 50 is rotatably mounted, on the clamping plate 54 side facing an eccentric 64 and on the side facing away from the clamping plate 54 has a coaxial portion 66. Between the eccentric portion 64 and the head portion 66, an outwardly extending coaxial annular flange 68 is formed. The eccentric portion 64 is disposed in a slot 70 formed in the folding blade 12. By rotation of the eccentric 50 of the eccentric portion 64 is rotated, whereby the height of the folding blade 12 is adjusted.
  • a pin head 72 is formed, which bears against the outside of the head portion 66. By rotating the pivot pin 60 in one direction, the peg head 72 exerts a clamping force on the eccentric 50, thereby fixing it in position.
