Definitions

  • the invention relates to a device for preventing printing unit damage in the case of printing carrier web tears in rotary printing presses, with a pair of clamping rollers arranged behind a printing unit, which can be driven in trouble-free operation at approximately machine speed, between which the printing carrier web can be carried out without contact and in which a roller can be displaced or pivoted in this way that when a print carrier web tear occurs, the print carrier web can be detected by the pair of pinch rollers.
  • a device of the above specified type is already known from DE patent 2156 505.
  • the pair of pinch rollers can be driven with gear trains at approximately paper web speed both during trouble-free operation and during the catching process.
  • it is disadvantageous that the response speed when a web break is detected is relatively high, since with the pivoting movement with which a roller is brought up against a stationary roller, the drive gearwheels for the pivotable roller also remain in engagement and thus also with have to be pivoted.
  • the object of the invention is to improve a device of the type mentioned in such a way that the response speed is greater, i. that is, the response time becomes shorter than in the known device.
  • the side walls 1, 2 shown in FIG. 1 are arranged behind the last printing unit, since the paper catching device shown in FIGS. 1 and 2 should preferably be arranged after the last of a plurality of printing units arranged one behind the other.
  • This comprises a stationary roller 3, which is arranged with its axle journals 4, 5 in bearings 6, 7 between the side walls 1, 2.
  • the roller 3 is driven via the elongated journal 4 via two bevel gears 8, 9 by a main drive shaft 10, which runs horizontally laterally on the printing presses in the usual way, preferably in such a way that the peripheral speed of the roller 3 is at least the same as the paper web speed or is slightly above this in order to compensate for response delays.
  • a rotatable cross member 11 is arranged between the side walls 1, 2, which can for example have a circular cross section.
  • levers 12, 13 are pivotable, which are pinned thereon, and which hold an axis 14 between their upper ends, on which the second roller 15 of the pinch roller pair 3.15 is arranged via bearings 16.17.
  • the roller 15 which can be pivoted about the crossmember 11 assumes the position shown in FIGS. 1, 2, in which it is driven by a friction wheel 18 likewise at machine speed or preferably at a speed above it.
  • the friction wheel 18 is seated on a shaft 19, which is arranged in bearings in the left side wall 1, which are not specified in any more detail.
  • a pulley 20 is wound, which is partially wrapped around by a flat belt 21, which is guided at its upper end around a further pulley 22 which sits on the elongated pin 4 of the stationary roller 3.
  • the pivotable roller 15 can be driven directly from the stationary roller 3.
  • the position of the pivotable roller 15 shown in FIGS. 1 and 2, in which the friction wheel 18 can drive the roller 15, is fixed by a pawl mechanism 24, 25.
  • an electromagnet 26 receives a control signal, whereby the armature pulls the locking lever 25 upward and the pawl 24 is released.
  • the tension spring 23 is now capable of the levers 12, 13 in the clockwise direction, i. H. to pivot upwards so that the roller 15 is pulled to the roller 3.
  • the drive for the roller 15 is separated, since the roller 15 is released from the friction wheel 18 when the levers 12, 13 are pivoted.
  • the roller 15 was preferably driven at a speed slightly above the paper web speed, so that even as a result of unavoidable frictional losses when the roller 15 rotated freely on the shaft 10, it could be set at a peripheral speed on the roller 3 which at least as high as the paper web speed.
  • the roller 15 is placed against the roller 3, that between the rollers 3, 15 continuous paper web A coming from the last printing unit is gripped and clamped. After the roller 15 abuts the roller 3, the roller 15 is then driven by the permanently driven roller 3.
  • the rollers 3, 15 can be plastic or rubber coated.
  • the device according to the invention in particular the high response speed in high-speed machines ensuring that the torn end, for example, out of the dryer and the paper web supplied from the last printing unit are wound around the pair of pinch rollers or around one of the pinch rollers, so that the functionality of the printing units is preserved.
  • the pivotable roller 15 was driven by a friction wheel 18 in the fault-free state.
  • a gearwheel can also be used instead of a friction wheel, which could then mesh with a gearwheel that can be pulled up on the journal of the pivotable roller.
  • another drive for example a toothed wheel drive or a toothed belt, can be used.
