Definitions

  • the present invention relates to a device for automatically catching a paper web torn during a run, which is provided with means for introducing the torn paper web into means for withdrawing the web.
  • the invention finds a particularly advantageous application in the field of printing and, when a paper web is torn when it is passed through an offset printing machine, prevents clogging by winding the paper web onto a blanket cylinder of the last printing unit.
  • Offset printing units usually consist of four parallel cylinders, which are in surface contact with one another via one of their surface lines.
  • the printed paper web runs between the two central cylinders, the so-called “blanket cylinders", which are surrounded by a linen blanket which is covered with an elastomeric material. Since the printing ink used to print the paper web is generally very viscous, the printed web tends to stick to the damp blanket cylinders.
  • the paper web is tensioned using rollers. These roles are e.g. the feed rollers arranged in front of the printing units and the cooling rollers arranged behind the printing units and the dryer. The tensioned paper web is thus released from the damp blanket cylinders, this detachment being interrupted abruptly in the event of the web tearing.
  • a hot air dryer with a total length of, for example, between 8 and 12 meters is provided serves to evaporate the solvents of the ink applied to the paper web and to polymerize their resin.
  • This dryer is arranged after the printing units and is traversed by the running printed paper web without it being supported by rollers. Since the dried paper web is less elastic than the moist paper web, the paper web can tear in the dryer. If the paper web tears in the dryer, it usually wraps around a blanket cylinder of the last printing unit due to the adherence of the ink applied to the paper web, which in some cases can develop considerable adhesive forces.
  • the number of paper layers reaches a value which is large enough to destroy the blanket or even the cylinders.
  • the risk of malfunction is all the greater as two layers of paper are wound onto the blanket cylinder with each revolution, one of the layers of paper coming from the printing unit and the other from the dryer.
  • This device is arranged between the last printing unit and the dryer.
  • the main component of this device consists of a pair of pinch rollers, which comprises a stationary roller arranged laterally below the paper web in progress and a pressure roller arranged above the paper web, both rollers being set in rotation in accordance with the throughput speed of the paper.
  • the two rolls are pushed apart so that the printed, moist paper web can pass through without touching it and without smearing occurring. If the paper web breaks, the tear of Optical detectors, which are attached to the output of the last printing unit, are clearly detected, and a trigger signal is sent without delay to a mechanism that holds the pinch roller that has moved away. The pinch roller is then released and brought into a position to act on the torn paper web.
  • the paper web coming from the last printing unit continues to run and is wound around one of the two pinch rollers of the device under consideration, instead of being wrapped around a blanket cylinder of the printing unit.
  • the diameter of the roll around which the paper wraps increases as the other roll moves away to allow the paper to be picked up.
  • the torn paper web wrapping around the pinch rollers is covered with damp printing ink, so that it is difficult to remove the paper stuck to the roller when the printing machine is stopped.
  • DE-A-3 735 330 Another safety device for reacting to web breaks is known from DE-A-3 735 330.
  • a new automatic device for catching a paper web torn in the passage is proposed according to the invention, with means for introducing the torn paper web into means for removing the web, the device allowing this torn paper web to be automatically pulled into a storage container without being wrapped around any roll.
  • the means for drawing off comprise two parallel rollers which are arranged on one side of the horizontally traveling paper web in such a way that the axes of the rollers lie horizontally and are oriented perpendicular to the direction of movement of the paper web, the device having drive means for rotationally driving the two Rolls in the opposite direction, which are in slight surface contact with one another along one of their surface lines, so that the rolls have a surface speed which approximately corresponds to the speed of movement of the paper web.
  • the device according to the invention advantageously allows the torn web to continue to be captured. Until the printing machine has come to a complete stop, the torn paper web is inserted between the rotating rollers and pulled by them at the speed of the web in order to be drawn off into a storage container without the paper web being wrapped around one of the rollers of the device.
  • the insertion means consist of a deflection device which is arranged on a side of the paper web opposite the rollers and which is provided with blower means arranged opposite a receiving area formed by the rotating rollers.
  • the deflection device is supplied with compressed air as soon as a monitoring system has verified that the paper web has been torn off.
  • the deflection device of the device is supplied with compressed air and the blower means exert a blower pressure on the torn paper web, causing it to move between the two parallel, rotating rollers is introduced.
  • the two rolls each have a detaching device which helps prevent the paper web from being wound around the two rolls.
  • an offset printing machine with a hot dryer which comprises two printing units (10, 20), each with two blanket cylinders (11, 11 ', 21, 21'), which have a horizontally continuous paper web (32 ) are arranged.
  • This device also comprises a dryer (4) arranged after the last printing unit (10).
  • the paper web (32) is stretched between two feed rollers (2, 2 ') and two outlet rollers (3, 3').
  • a monitoring system (5, 5 ') arranged directly behind the last printing unit (10) allows a break in the paper web (32) to be detected and a trigger signal to be sent to the automatic catching device according to the invention, which is shown in FIG. 1 arranged directly in front of the entrance of the dryer (4) and provided with the reference symbol (8).
  • the monitoring system (5, 5 ') can be arranged anywhere between the last printing unit (10) and the two outlet rollers (3, 3').
  • This device has means for pulling off the torn paper web, in this case two rollers (30, 31) of the same diameter which run parallel to one another and are arranged on the same side of the horizontally moving paper web (32), the diameter being approximately 120 mm.
  • the two rollers (30, 31) are arranged below the paper web (32) in such a way that their axes are horizontal and perpendicular to the direction of movement of the paper web.

  • the roller (30) rotates in the sense of the direction of movement of the paper web (32) and the roller (31) in the opposite sense.
  • the two rollers set in rotation produce a receiving area (12) directly below the paper web (32).
  • the roller (31) is attached to a swiveling device described below in such a way that the two rollers are in slight surface contact with one another at the level of their projections (54 ') and in particular at the level of one of their surface lines.
  • the roller (30) is rotatably held in two bearings (33 and 34) which are provided in two parallel bearing housings (35, 36).
  • the roller (30) comprises a drive pulley (61) fastened to one of its bearing journals by means of a wedge connection, which is connected via a belt (40) to a pulley (39) of a drive means, in this case an electric motor (37).
  • the motor (37) is a variable speed motor and is mounted on a bracket (38) connected to the bearing housing (36) such that the axis of the motor (37) is parallel to the axis of the roller (30).
  • the role (30) is from the Motor (37) driven by the speed of the paper web (32).

  • the pivoting device in this case consists of two levers (42, 43) which are rotatably supported on the bearing housings (35, 36) by means of two pivot bolts (44, 45).
  • Two pneumatic cylinders (46, 47) which are rotatably attached to the bearing housings (35, 36) by means of pivot bolts (48, 49) can act on the levers (42, 43) by means of their rods (50, 51).
  • two screws (52, 53) are provided for regulating the surface contact of the roller (31) with the roller (30) by limiting the pivoting movement of the levers (42, 43).
  • the pneumatic cylinders (46, 47) are activated so that the contact between the two rollers (30, 31) is "light” in order to avoid heating the rubber applied to the surface of the roller (31).
  • the speed of rotation of the motor (37) is converted into an electrical voltage, which is transmitted in an electronic circuit (58) and compared with a voltage originating from the main drive of the printing press (not shown) and transmitted from the current conductor (59).
  • the electronic circuit (58) generates a precision supply voltage (60) for the motor (37) so that its speed of rotation is proportional to the speed of the printing press.
