Definitions

  • the invention relates to a sword folding machine for cross folding with at least one sword, a pair of folding rollers and one Device for feeding sheets to the folding rollers.
  • the person skilled in the art has various options for folding printed products Folding machine types available.
  • One of them is the knife folding machine, also called sword folding machine, which is used for the folding process for example a vertically movable sword and two has opposite rollers.
  • the sheets to be folded are individually in a row with a transport device over the Folded roller pair promoted and with the vertically descending Sword struck between the rotating folding rollers. Of the folded fold is then captured by the folding shafts and when passing through the sheet through these folding rollers a Fold break.
  • Folding machines are also known in which the folding is performed by a rotatable sword takes place on the circumference of a likewise rotatable Sword bearer is arranged.
  • the movement of the Schness is controlled, for example, via a gear wheel that sits on the axis around which the sword rotates is.
  • Several swords can be arranged on the sword carrier.
  • Such sword carriers are in particular as sword fold cylinders known.
  • Folding machines with rotating swords are produced per revolution the sword bearer a number of folds, which the number the swords match. Sheets have to be folded, the smaller ones are as the division of the folding cylinder, these are sheets pulled apart as far as they are fed to the folding rollers, that the division of the folding cylinder is achieved. The pull apart however, the bow causes unnecessarily high and problematic Processing speeds and precise alignment the sheet to achieve high folding accuracy. This Alignment to stops is difficult and complex and limited the speed and therefore the performance of the folding machine.
  • the invention has for its object to a folding machine create, which avoids the difficulties mentioned.
  • the task is in accordance with a generic folding machine Characteristic of claim 1 solved.
  • the adjustment takes place in the sword folding machine according to the invention to different sheet formats by changing the Sword movement speed.
  • transitioning to one the smaller format is therefore in accordance with the format reduction the speed of the sword movement increases.
  • the adaptation the speed of a format change is special very flexible with a servo motor and does not require any artificially pulling the sheets apart.
  • the invention enables higher folding accuracy and at the same time higher performance, especially for formats that are smaller than the maximum format are. It is also essential that the bows run freely and can be folded without a stop.
  • the folding accuracy can be increased even further if after
  • the sword fold movement is controlled in this way or is regulated that the speed too changes during a folding cycle.
  • the speed regulated or controlled so that before and after the folding moment the speed of the sword is slightly higher than that average speed of movement and that at the folding moment the Speed is lower than the average speed.
  • the integral over the speed difference between the medium speed and effective speed over a full cycle must be zero be.
  • the irregular movement of machine parts can, however lead to significant vibrations. But now, for example on the shaft of the sword bearer an accelerable in the opposite direction Compensating mass arranged, so the above Overall speed changes nonetheless low-vibration carry out.
  • the principle of leveling compounds is for all types of construction of limping movements, i.e. also for all types of sword folding machines applicable e.g. over a gearing with a swivel lever that is fed in a revolving curve is rotated in the opposite direction relative to the folding cylinder can.
  • the control curve can be fixed in the room or for one Dynamic limping cyclically in the axial direction of the sword folding cylinder be moved.
  • Types of construction of such balancing compounds are known.
  • the sword folding machine according to the invention is particularly advantageous in a commercial processing line in the direction of transport seen in front of the sword folding machine at least one Printing unit and a cross cutter.
  • the format is variable very limited.
  • a commercial processing line according to the invention can in without expensive conversion work one work cycle commercial products with different formats be finished. Such an operation can except printing, folding and cutting also other work steps, especially perforating, punching, gluing, but also include inkjet lettering or numbering.
  • FIG. 1 shows a sword holder 1 with two swords 2, which are rotatably mounted on the sword carrier 1 in a manner known per se are.
  • the sword carrier 1 is about the axis of rotation 5 in Direction of arrow 3 with a servo motor, not shown here driven counterclockwise. Turn the two swords 2 when rotating the sword carrier 1 in the direction of arrow 4 in Clockwise, with a front edge 2a dotted on the dot-dash line drawn curve 18 moves.
  • the sword carrier 1 can but also as a sword fold cylinder with more than two swords 2 be formed.
  • the sheet 7 is fed to the two folding rollers 11 with a double band 10 in the direction of arrow 13. Further, Sheet 7, not shown here, are individually and in a row transported one after the other. In Figure 1, the arc 7 thus follow in series from the left further sheets not shown here, the are captured by the double belt 10 one after the other.
  • FIG. 2 corresponds to that according to FIG 1, with only one sword 2 on each sword carrier 1 is arranged.
  • the sword bearer is 1 mounted on a shaft 14 on a frame-shaped machine frame 19 is mounted and the one not shown here Servomotor is rotatable on a drive wheel 17.
  • the Sword 2 is used to generate a superimposed rotary motion a toothed belt 20 connected to a sun gear 21, which is in the machine frame 19 is stored.
  • a cyclical one Movement of the sun gear 21 can be the rotational movement of the Sword 2 can be influenced.
  • Shown here only in a hint Plates 22 serve to support the two folding rollers 11.
  • the servo motor 17 alone enables the rotational speed of the Sword bearer 1 to change, but only without mass balance for light versions without major vibrations should. Suitable types of construction are known to those skilled in the art Leveling compounds related to the idea of the boxer engine, known The speed of rotation of the sword carrier 1 can be within of a folding cycle depending on the version or operating mode be or change.
  • the speed of rotation of the sword bearer 1 depends on the format the bow 7 adjusted. If the sheet format is changed adjusted accordingly the speed of rotation of the sword carrier 1. When moving to a smaller sheet format, the speed of rotation of the sword carrier 1 increased. It is with it not necessary when moving to a smaller format accordingly in a row of sheets 7 arranged one behind the other pull apart and align.
  • the speed of rotation of the sword carrier is preferably 1 controlled or regulated by means of the servo motor so that its Rotation speed changes during one revolution. In order to it is possible to fold different formats. Even with one Format changes can be made on the edge 2a of the sword 2 optimal relationships between the speed of the bow 7 and that of the active edge 2a.
  • the speed is relative to the average speed increased before and after wrapping and when wrapping slows accordingly.
  • the movement of the swords 2 and thus curve 18 is retained, but the speed changes before and after wrapping the sheet 7.
  • the transport speed of the sheets 7 to the folding rollers 11 can be constant.
  • the turning of the sheet 7 can also be done if the transport speed of the sheets is not constant is held, e.g. in the area where the sword 2 immersed, is also regulated or controlled. this happens by appropriate control of the double belt 10, preferably also via a servo motor, not shown here.
  • Control can be achieved that the sword tip 2a when immersed with respect to sheet 7 neither ahead nor behind running.
  • the folding rollers 11 leaving sheet 7 despite different to be processed Formats are folded precisely in a simple manner.
  • the invention also has the advantage of smaller formats in the series can be pushed closer together and thus the transport speed can be reduced.
  • the folded sheets 7 can one not shown here but known per se Folders are fed and folded accordingly in this will.
  • FIG. 3 shows a variant of a sword folding machine according to the invention 30, in which a sword 31 in the manner of a yoke is formed and a linear with respect to two folding rollers 32 Floats.
  • An edge 39 corresponds here the edge 2a of the sword 2.
  • the movement mentioned is by means of a cam 36, which cooperates with a wheel 37, that at a distance from an axis of rotation 35 on a two-armed Lever 33 is mounted. If a curve section 36a comes along the wheel 37 in contact, the sword 31 against the Folding rollers 32 move and effect the turning described above of a sheet 7, not shown here, between the folding rollers 32.
