Definitions

  • the present invention relates to the area of rotary staplers intended for stapling printed matter, e.g., newspapers and brochures, the pages of which come from a printing press on a double-sided printed running paper web.
  • Each double-sided printed paper web is collected and synchronised to each other, whereupon the collected paper webs define continuous product parts that after stapling are cut off into finished products.
  • the collected paper webs are cut off into product units, which after that are led into the rotary stapler and there are stapled together into finished products.
  • the invention relates to wire advancement and wire pick-up in such a machine.
  • one or more paper webs run, usually in so-called broadsheet format, at a constant speed on each other, which paper webs together form a continuous row of product parts in the form of printed matter.
  • the paper webs with the product parts run past a rotary stapler that staples together the paper webs, the paper webs after that being cut off halfway between the stapling points and forming separate products. In doing so, the products constitute finished printed matter after folding has been effected along the staplings.
  • the paper webs in broadsheet format will be folded only once along the web. Usually, these products will not become stapled at all since the wire staples have to be inserted in the longitudinal direction. However, so-called tabloid products are folded twice. First along the web, at the same time as the web becomes cut lengthwise, and next transverse to the direction of motion. Thereby, the wire staples have to be inserted transverse to the web in the second folding line.
  • the stapling can be effected before as well as after the paper web has been cut off transverse to the direction of motion, by means of a web-breaking roller. This technique of stapling tabloids in the fold is well-known since before.
  • the device comprises also a staple bending device that is formed with two parts each one of which is turnable around a separate axis.
  • a device according to this patent specification is adapted to stapling over a saddle and that is clearly shown in Figures 1 and 2 thereof. Accordingly, it cannot be used for linear stapling in the fold, before the last folding (quarter-fold) is made.
  • a first solution is that the wire advancement is carried out by a stepping motor having a control system, which is a very variable solution that is adaptable to many operational cases, however the speed is very limited since the motor and the wire have certain inertia and it is not possible to accelerate and brake arbitrary fast.
  • a third solution is shown in DE 10 2004 040 851 , which solution for the wire advancement uses two motors in the proper "feeder housing". In the "collect mode", the first motor drives continuously at half speed on the wire coil and advances wire in a storage. A second motor that is closer to the machine advances at full speed, intermittently, at intervals, wire into the machine. This solution decreases the inertia and friction of the wire for the proper feeding motor since it operates with only a small wire loop.
  • the solution is complicated since a complicated control system including two motors is required.
  • the present invention aims at providing an improved continuous wire advancement device for a rotary stapling or stitching machine.
  • a further object of the invention is to provide a continuous wire advancement for an unsymmetrical rotary stapler, where the stapling forks accordingly are placed after each other.
  • Yet an object of the invention is to provide a continuous wire advancement for an unsymmetrical linear stapling machine.
  • the invention concerns a wire advancement device in a rotary stapling machine, preferably a linear stapling machine, which wire advancement device comprises a wire source, an advancement system and a driving motor arranged so that wire from the wire source is continuously advanced via the advancement system to a first wire introduction assembly mounted in a staple pick-up zone in a rotary stapling machine.
  • the wire introduction assembly is provided with a cutting edge that co-operates with a corresponding cutting edge of a stapling fork in turn mounted in a stapling cylinder rotating around a first axis, the cutting edges being arranged to cut off a length of wire advanced to the wire introduction assembly and forming a staple blank at each revolution the stapling fork passes the wire introduction assembly.
  • the wire advancement device is provided with a second wire introduction assembly co-operating with a second stapling fork placed in the same axial position on the stapling cylinder as the first stapling fork in order to cut off a second continuously advanced length of wire forming a staple blank.
  • guide means are arranged to allow that the first wire introduction assembly only delivers staple blanks to one of the stapling forks and to allow the second wire introduction assembly to only deliver staple blanks to the other one of the stapling forks. This is effected by the guide means providing a displacement of the respective wire introduction assembly in the direction away from the stapling cylinder to allow free passage of a stapling fork.
  • the two stapling forks are placed after each other in the stapling cylinder, which means that they are in the staple pick-up zone simultaneously.
  • the guide means comprises cam followers mounted one to each wire introduction assembly and cam curves mounted to the stapling cylinder and that are formed to change the positions of the cam followers in directions perpendicular to the first axis.
  • a primary cam follower of the first wire introduction assembly is arranged to be displaced by a primary cam curve situated at the second stapling fork, so that the second stapling fork clears the first wire introduction assembly.
  • a secondary cam follower of the second wire introduction assembly is arranged to be displaced by a secondary cam curve situated at the first stapling fork, so that the first stapling fork clears the second wire introduction assembly.
  • the cam curves of the guide means are rotatable together with the stapling forks around the first axis.
  • a staple forming device preferably in the form of a forming wheel comprising a forming roller, is mounted in the staple pick-up zone after the two wire introduction assemblies in respect of the direction of motion of the stapling fork.
  • the staple forming device is arranged to form staples picked up by both stapling forks.
  • the invention concerns a method for wire advancement in a rotary stapler in which one motor continuously advances wire from a wire source to a wire introduction assembly, one motor continuously advancing wire from a second wire source to a second wire introduction assembly, a first stapling fork in a stapling cylinder cutting off and picking up a staple blank from only one of the wire introduction assemblies while a second stapling fork in the stapling cylinder cutting off and picking up a staple blank from only the other one of the wire introduction assemblies.
  • the first stapling fork and the second stapling fork are trailing each other, the same accordingly being in the staple pick-up zone simultaneously.
  • the wire advancement to the two wire introduction assemblies is driven by one and the same motor.
  • each stapling fork carries the respective staple blank to a forming wheel that forms the staple blank into a staple.
  • guide means displace, on one hand, the second wire introduction assembly or the first stapling fork away from the wire pick-up position thereof, and on the other hand the first wire introduction assembly or the second stapling fork away from the wire pick-up position thereof.
  • the wire advancements are effected at a constant speed.
  • the invention concerns a wire advancement device according to the above that is intended for a rotary stapler, which by a stapling module placed in a rotating stapling cylinder applies wire staples provided with penetrating branches through the plurality of material layers of a printed product.
  • the wire staples are formed by wire being advanced to a cutting assembly where a stapling fork cuts off a length of wire that after that is formed into a staple, which upon the stapling is pressed by a punch mounted in the stapling fork in the stapling module through the material layers, whereupon the branches of the wire staples are formed against a die in a die cylinder counter-rotating in relation to the stapling cylinder,
  • a stapler for which a wire advancement device according to the invention is extraordinarily suitable, which stapler is to be mounted in the proper folding part of a printing press, the products becoming stapled before the last folding is carried out, so-called quarter fold.
  • the stapling is effected against a cylinder surface that requires a non-linear motion of the stapling head.
  • the present stapler is adapted to be integrated in the folding assembly in the printing press in order to allow the stapling to be effected before the last folding is carried out.

  • the die may be made passive, the same being possible to mount on already existing cylinders.
  • a wire advancement device is suitable for a linear stapling machine that is provided with a stapling fork rotating around a first axis as well as with a die counter-rotating around a second.

  • a first guide means is arranged to turn the stapling fork by 90" during its motion to as well as during its motion from a staple pick-up zone, which is defined as a zone having an extension that corresponds to 1/4 to 1/3 of a stapling cylinder circumference, in relation to a stapling zone so that the orientation of the stapling fork is parallel to the first axis in the staple pick-up zone, but that the stapling fork is perpendicular to the first axis in the stapling zone.
  • the staple pick-up zone and the stapling zone are defined in the stapler shown and described here as the respective distances along which the stapling fork is not turned during a cylinder revolution.
  • the wire staple Upon stapling through the product part, the wire staple will then be essentially parallel to the direction of motion of the product part, and upon picking-up, be essentially perpendicular to the direction of motion of the product part. Furthermore, at least one second stapling fork rotating around the first axis and trailing the first stapling fork is arranged to roll off against a corresponding second die counter-rotating around the second axis so that the branches of a wire staple that is carried by the second stapling fork can be forced through a plurality of layers of the same product part running through the rotary stapler and thereby be formed against the second die.
  • the first guide means is arranged to turn the second stapling fork by 90° to and from the staple pick-up zone in relation to the stapling zone so that the orientation of the second stapling fork is parallel to the first axis in the staple pick-up zone and perpendicular to the first axis in the stapling zone.
  • the wire staple is in this connection essentially parallel to the direction of motion of the product part.

  • a cutting assembly is mounted at the staple pick-up zone and provided with a first wire introduction assembly and a second wire introduction assembly, as well as that third guide means are arranged to allow that the first wire introduction assembly only delivers staple blanks to one of the stapling forks and that the second wire introduction assembly only delivers staple blanks to the other one of the stapling forks by a pushing-away of the respective wire introduction assembly. It is also possible that the pushing-away actuates the stapling fork instead of the wire introduction assembly.
  • the third guide means comprises third cam followers mounted one to each wire introduction assembly and third cam curves that are formed to change the positions of the third cam followers in directions perpendicular to the first axis.
  • a primary third cam follower of the first wire introduction assembly is arranged to be displaced by a cam curve situated at the first stapling fork, so that the first stapling fork clears the first wire introduction assembly

  • the holding of the staple in the stapling fork at its carriage from the staple pick-up zone to the stapling zone is effected either by a damping mechanism having grooves/notches and integrated in the stapling fork or by a magnet action arranged in the stapling fork.
  • the holding of the staple has to be integrated in the stapling fork since this is turned during the rotation of the stapling cylinder.
  • Figure 1 shows a linear stapling machine 10 of rotary type provided with a stapling cylinder 11 in which two stapling modules 12, 12' situated in pairs after each other are mounted at the circumference of the stapling cylinder.
