Definitions

  • the invention relates to a sword folder with a folding blade and a pair of folding rollers associated transport means by which a signature can be conveyed to a stop carrier unit before folding in a transport plane.
  • a leading edge stop and side edge stops are provided so that the signature undergoes guidance during the deceleration or braking operation and aligned along the predetermined by the geometry of the folding blade coordinates.
  • Known designs of Schwertfalzwerken typically have motor-adjustable stop carrier with fixed fixed stop fingers, often provided for a minimum format of the signatures to be processed, in order to get between the transport device in the transport path of the signature.
  • Schwertfalztechnike Falzrnaschinen be used in particular for the production of cross fractures, for example in so-called combination folding machines, which have both at least one pocket and a Schwertfalzwerk.
  • a sword folder for a rotary printing machine has a leading edge stop, which serves the positioning under the sword and on the Falzwalzencru of brought up by conveyor belts signatures.
  • the leading edge stop carrier unit is movable parallel to the transport plane, and the leading edge stopper is movable perpendicular to the transport plane. It extends continuously over several conveyor belts, with recesses in the leading edge stop forming a sufficiently clear width for passage of the conveyor belts past the leading edge stop.
  • marking formation can occur in the case of firmly provided and spaced stop fingers of a leading edge stop.
  • no secure stop edge is formed for the leading edge of the signature, so that at a sharp deceleration of the signature this can come to lie obliquely above the folding gap. This twisting of the signature can cause folding inaccuracies.
  • the invention is therefore based on the object to provide a blade folder with a front stop, which reduces marking formation and folding inaccuracies by distortions of the signature.
  • the invention is based on the object that an automatic adjustment of a stop configuration is to be made possible depending on material and production parameters.
  • the sword folding mechanism comprises a transport device associated with a folding blade and a pair of folding rollers, by means of which at least one signature can be conveyed to a stop carrier unit in a transport plane before the folding operation. It is characterized in that the stop carrier unit is movable relative to the folding blade substantially parallel to the transport plane and at least one of at least the position line of the folding blade has up to an extreme side edge line continuously extending leading edge stop, which is movable substantially perpendicular to the transport plane.
  • a transport device may include, for example, transport rollers or conveyor belts. An extreme side edge line is determined, for example, by a maximum signature width to be processed.
  • the transport device comprises conveyor belts, which extend continuously to a downstream of the sword folder delivery, so even without Kreuzbruchfalzung a passage of the signature is easily and easily possible, it is particularly advantageous that a group of pulleys for the conveyor belts for redirecting the conveyor belts on the leading edge stop along the side facing away from the transport plane side is provided.
  • the construction of the Schwertfalzwerkes invention is preferably designed such that the stop carrier unit has at least one substantially perpendicular to the position line of the folding blade movable Thisantschschlitten with side stops for aligning the signature along predetermined by the geometry of the folding blade coordinates.
  • at least one of the side stops is movable substantially perpendicular to the transport plane and can be transferred from a rest position into at least one active position and back. According to the format of the signature to be folded, the stop carrier unit and / or the side stop slide together with the side stops can be adjusted fully automatically.
  • At least one hold-down band is provided above the transport plane.
  • an associated group of pulleys for redirecting the hold-down belt on the leading edge stop over along the side facing away from the transport plane side is provided.
  • An associated group of pulleys for a conveyor belt or hold-down belt is typically received on the side stop carriage.
  • the associated conveyor belt or hold-down belt can be translated according to the movement of the side stop slide or moved in the same direction. It is particularly advantageous if at least one deflection roller in a certain group of deflection rollers is movable substantially perpendicular to the transport plane. Thereby, the associated conveyor belt or hold-down band can be tightened when the said deflection roller is in a first position and relaxed when the deflection roller is in a second position, so that a translation or displacement of the conveyor belt can take place in the same direction as the side stop carriage.
  • At least one side stop is provided on the side stop carriage for a first region and at least one side stop for a second region of possible positions between a minimum and a maximum position of the side stop carriage.
  • a first side stop or a second side stop can be used.
  • at least one side stop is received on a group of deflection rollers on the sides facing the folding blade and / or at least one side stop is received on at least one group of deflection rollers on the side facing away from the folding blade.
  • a suitable actuator may be a valve-controlled pneumatic cylinder or a servomotor.
  • the control unit controls at least one actuator as a function of at least one signature parameter, for example of the format, of a material or production parameter in such a way that the stop carrier unit and / or the front edge stop and / or at least one side stop are positioned in accordance with the format of the signature to be folded.
  • the integration of the side stops and the leading edge stop in a stop carrier unit collisions between the side stops and the leading edge stop are avoided when changing their position to each other.
  • the side stops can preferably be brought independently from the rest position to an active position and back.
  • the movement of the stop carrier and / or the movement of at least one stop finger and / or at least one side stop is carried out with particular advantage by means of an actuator.
  • a suitable actuator may be a valve-controlled pneumatic cylinder or a servomotor.
  • a control unit for the Schwerfalzwerk controls at least one actuator as a function of at least one material or production parameter, ie a signature parameter, for example of the format, such that a positioning of the stop carrier and / or at least one leading edge stop and / or at least one corresponding to the format of the signature to be folded Side stop carriage and / or at least one side stop takes place.
