Definitions

  • the invention relates to a rotary cutting machine for the printing industry, which has an upper blade and a lower blade, which form an adjustable kerf and which are each rotatably mounted with a knife shaft on a machine frame, with a control device, with a blade drive and an adjusting device, with at least one of said knives for adjusting the cutting gap in the longitudinal direction of a knife shaft is adjustable, wherein a zero position and from this a cutting position are adjustable, the zero position of the adjustable blade is automatically determined by a signal generator, and the adjusting device has an adjusting, with the adjustable knife by a signal generator controlled by the zero position is automatically moved into the cutting position.
  • the cutting gap between upper blade and lower blade must be set in a range of, for example, 0.03 mm to 0.035 mm.
  • the adjustment is made via an adjusting spindle with vernier.
  • the upper knife or the lower knife is adjusted.
  • the correct setting of the kerf requires a very precise and careful work. If you do not work with the necessary care, the kerf is either too big or too small. If the cutting gap is too large, the cut quality is insufficient and if the cutting gap is too small, the expensive blades of the upper knife can break.
  • the adjustment of the cutting gap is usually done by hand, the adjustable knife is first moved from a starting position to the zero position and driven by this in the opposite direction in the cutting position.
  • a certain mechanical understanding is necessary. As a rule, therefore, a mechanic must be consulted.
  • the invention has for its object to provide a rotary cutting machine of the type mentioned, in which the kerf can be easily and safely adjusted.
  • the object is achieved in that the detectable by the signal generator zero position is detectable by a rotational movement of the adjustable blade and the zero position on the co-rotating by friction other knife is detectable.
  • the adjusting device has an adjusting drive.
  • the zero position can thus be approached automatically, and starting from this, the cutting gap is set. Once the zero position is reached, the adjustable knife is stopped and with the adjusting drive moves in the opposite direction in the cutting position. The adjustment of the kerf can thus essentially be done automatically. Since the setting is automatically controlled, false manipulations can be ruled out.
  • the adjustable blade With the adjusting drive, the adjustable blade can be moved from an adjustable starting position to the zero position according to an embodiment of the invention.
  • the kerf width In the initial position, the kerf width is 1.0 mm, for example. Such a kerf is easily and safely adjustable without the risk of blade breakage.
  • the other knife When starting up the zero position is rotated according to an embodiment of the invention, the other knife with the knife drive. When the zero position is reached, the adjustable blade is rotated by friction on the other knife.
  • the signal generator is designed so that it detects this turning of the adjustable blade.
  • a rotational movement can be determined particularly reliably and safely with a rotary encoder.
  • the rotary encoder sends a signal to the adjusting drive, which stops immediately and then moves the adjustable blade to set the cutting gap in the opposite direction.
  • control device stores the zero position and that starting from this stored value, the adjustable blade is automatically moved into the cutting position.
  • a further rotary encoder is provided, with which the cutting gap is determined during the process in the cutting position.
  • the adjustment of the adjustable knife is preferably carried out with an adjusting spindle, which is in engagement with a bush or a carriage.
  • the knife shaft of the adjustable knife is mounted on this bushing or the adjusting spindle. With the adjusting spindle very precise movements are possible.
  • a specific cutting gap width can be predetermined, which is then set automatically. Since the process essentially proceeds automatically, it is much easier to change the kerf width. This makes it possible to adapt the kerf width to the corresponding product or to vary the kerf width.
  • the lower blade is adjusted.
  • the upper blade is adjusted.
  • Rotary cutting machine 1 shown has a machine frame 2, on which an upper blade 5 and a lower blade 7 are mounted.
  • the upper blade 5 is driven by a motor 3, which is driven by a not visible here under a cover 4 arranged drive member.
  • the drive member acts on a second shaft, not shown here, of the upper blade 5.
  • the upper blade 5 has at its periphery a plurality of blades, which are made of a suitable hard metal and clamped.
  • the lower blade 7 forms the counter blade and has a ring 8 made of hard metal, which cooperates with the blades 6.
  • the upper blade 5 and the lower blade 7 are according to FIG. 2 rotatable about parallel axes A1 and A2.
  • the lower blade 7 has a blade shaft 11 which is rotatably supported by two bearing elements 17 in a sleeve 16.
  • the sleeve 16 is displaceable in a bearing bore 21 of the machine frame 2 in the longitudinal direction of the blade shaft 11, but secured against rotation.
  • an adjusting device 10 is provided with an adjusting 12.
  • This has an adjusting motor V, which is preferably a controllable electric motor and with which a gear 13 is driven, which is in engagement with a further, preferably larger gear 14.
  • an adjusting spindle 15 is fixedly connected, which acts on the sleeve 16.
  • the sleeve 16 in FIG. 2 to the left or moved to the right. Accordingly, the lower blade 7 is moved to the left or to the right.
  • the adjusting motor V is controlled by a controller ST here.
  • the upper blade 5 is driven by a further motor F, which may also be referred to as a milling motor. During the cutting process, the upper blade 5 is thus driven.
  • the rotatably mounted lower blade 7 is inevitably rotated in this case.
  • the rotational movement of the knife shaft 11 can be detected with a first rotary encoder D1. If the knife shaft 11 begins to rotate, this is detected by the first rotary encoder D1 and it sends a signal directly to the control device ST via a signal line 22.
  • a second rotary encoder D2 is provided to measure the movement of the spindle 15 in its longitudinal direction. This second rotary encoder D2 is connected via a further signal line 23 to the control device ST.
  • the cutting gap S to be set is determined according to FIG. 2 formed by a surface 19 of the upper blade 15 and a surface 20 of the lower blade 7.
  • the surface 19 is formed by surfaces of the blades 6 and by an inner surface of the hard metal ring 8.
  • the cutting gap S has in the cutting position of the adjustable lower blade 7, for example, a width of 0.03 to 0.035 mm. But there are also other gap widths conceivable here. In the FIG. 2 this distance is indicated by the arrows 18.
  • the gap width is here from drawing Reasons presented much larger than in reality.
  • the lower blade 7 with the in FIG. 1 shown knob 9 is moved to a position in that the distance between the surfaces 19 and 20 is substantially greater than the cutting gap to be set.
  • This distance is for example 1.0 mm. In principle, however, this distance can also be set automatically.
  • the setting process is triggered on a button, not shown here.
  • the control device ST then adjusts the adjusting motor V so that the lower blade 7 in FIG. 2 drives to the left.
  • the upper blade 5 is driven by the engine F.
  • the hard metal ring 8 thus approaches in FIG. 2 the upper blade 5.
  • the lower blade 7 begins to rotate.
  • the reason for this is the friction of the carbide ring 9 on the upper blade 5.
  • This rotational movement of the lower blade 7 is detected by the first rotary encoder D1 and this outputs a signal via the signal line 22 to the control device ST from.
  • the control device ST immediately stops the adjusting motor V, so that the upper blade 7 stops in the set position.
  • This position is in FIG. 3 illustrates and forms the zero position from which the kerf S is set.
  • the sleeve 16 and her lower blade 7 now move in FIG. 2 to the right. Between the two surfaces 19 and 20 thus again forms a distance. This distance is measured by the second rotary encoder D2 and transmitted via the signal line 23 of the controller ST.
  • the second rotary encoder D2 primarily measures the rotation of the spindle 15 which, however, is proportional to the distance between the surfaces 19 and 20.
  • the spindle 15 is rotated by a corresponding predetermined amount. As a rule, this is a partial rotation of the spindle 15.
  • the second rotary encoder D2 outputs a corresponding signal via the signal line 23 to the control device ST.
  • the control device ST stops here immediately the adjusting motor V and thus the further movement of the lower blade 7.
  • the cutting gap S is set with it and the rotary cutting machine 1 can be used as intended for cutting, for example, brochures, magazines and other printed products.
