Definitions

  • the invention relates to a single-sided corrugated cardboard machine with a machine frame, an upper and a lower corrugating roller and a press roller which interacts with the lower corrugating roller and is pivotably mounted on lever arms on the machine frame, with an adjustable stop arrangement associated with the lever arms and supported on the machine frame, and with it on the machine frame supporting, interacting with the lever arms adjusting devices that press the lever arms against the stop arrangement to limit the press nip.
  • the press roller It is generally known to mount the press roller rotatably in the lever arms and to actuate the lever arms with the aid of a pneumatically or hydraulically operating adjusting device in order to adjust the roller gap.
  • the press roller is either pressed directly against the lower corrugating roller or optionally against a stop.
  • the stop limits the movement of the press roller against the lower corrugating roller. It is also adjustable to adapt the gap width to the paper thickness.
  • the adjusting device must press the lever firmly against the stops, so that even with greater forces in the nip this is not increased unintentionally.
  • an adjustment device designed for high forces is required.
  • Such swinging is undesirable for several reasons. It can affect the quality of the paper. There is also considerable noise.
  • the service life of the rollers is also negatively affected.
  • the levers supporting the press rolls can experience a certain amount of deflection, whereby the accuracy of the roll gap is impaired.
  • the invention has for its object to provide a one-sided corrugated cardboard machine in which a particularly smooth running of the press roll is achieved.
  • stops are arranged so that they limit the movement of the lever arms away from the press nip.
  • the stops point in the opposite direction to the stops in conventional machines.
  • the lever arms are limited from the press nip against the stops to adjust the nip.
  • the nip is therefore fixed via a rigid mechanical connection. It has been shown that such an arrangement leads to a much quieter running of the press roll than in known machines in which the forces acting from the lower corrugating roll have to be absorbed by a hydraulic or pneumatic adjusting device.
  • the attainable smooth running of the press roll has a positive effect on the quality of the corrugated cardboard.
  • Another advantage of the machine according to the invention is that only a small force has to be applied to hold the lever arms against the associated stops.
  • the adjustment device therefore only serves to prevent the lever arms from lifting off the stops. However, this is normally not the case anyway, since the lever arms rest on the stops under their own weight or the weight of the press roller. In the known machine, the adjusting device has to overcome this weight in order to press the lever arms firmly against the stops.
  • the adjusting device is a pulling device. It can be formed, for example, by hydraulic adjustment cylinders.
  • the stops are supported on a rigid spring according to a further embodiment of the invention.
  • the spring can e.g. are formed by disc spring assemblies, e.g. give way when double layers of paper run through the nip.
  • the position of the stops determines the size of the nip. Since this must be changed in accordance with the paper thicknesses, one embodiment of the invention provides that the stops are formed by wedges which are arranged together on an adjusting shaft and interact with inclined surfaces of the levers.
  • the adjusting shaft can e.g. be motor-driven and provided with an encoder that can interact with an automatic process control. With such an adjustment of the stops, the levers can also be adjusted individually, which has proven to be advantageous.
  • the machine frame of a single-sided corrugated cardboard machine is generally designated 10.
  • An upper corrugated roller 12 is mounted on levers, one of which is shown at 11.
  • a lower corrugated roller 14 is rotatably mounted, which with the upper corrugating roller 12 cooperates in a known manner.
  • An application unit 15 for glue also interacts with the lower corrugating roller 14 in a known manner.
  • the section of the lever 11 which extends beyond the pivot point of the upper corrugating roller 12 is connected to a hydraulic cylinder 16. As a result, the corrugating roller 12 can be pressed against the corrugating roller 14.
  • a press roller 18 is rotatably mounted in the machine frame.
  • the lever 17 is pivotally mounted in the machine frame 10, as shown at 19.
  • the pivot point of the lever 11 for the upper corrugated roller 12 is otherwise designated 20.
  • the section beyond the pivot point of the press roller 18 of the lever 17 is articulated on a hydraulic cylinder 21 which is articulated on the machine frame 10 at the other end.
  • a stop surface 22 is provided on the side of the lever 17 facing away from the lower corrugating roller 14. It interacts with a stop arrangement 23, which is supported on the machine frame 10.
  • the adjusting cylinder 21 serves to hold the lever 17 against the stop arrangement 23. Without counteracting forces, the lever 17 lies against the stop arrangement 23 due to its own weight or the weight of the press roller 18. Only with certain vibrations could the lever 17 be lifted from the stop arrangement 23 to a certain extent. This is prevented by the adjusting cylinder 21.
  • the stop arrangement 23 is formed by two wedges 24, 25, which are supported on a stop surface 26 of the machine frame 10. On the opposite side they have an inclined surface which cooperate with inclined stop surfaces 27, 28 of the lever 17. The stop surfaces 27, 28 on the lever converge towards the center.
  • the wedges 24, 25 sit on left and right-hand thread sections of an adjusting shaft 29, which can be driven by a motor 30 via a gear 31.
  • a transmitter 33 is also attached to the gear shaft 32.
  • the respective position of the wedges 24, 25 can be set with the aid of an automatic control.
  • the sensor 33 shows the respective position of the shaft 29 and thus the wedges 24, 25 again. Their position determines the gap width. This can e.g. are displayed digitally by derivation from the transmitter signal.
  • the contact force of the lever 17 on the stop assembly 23 is increased by the paper pull.
  • the paper draw may be so strong that there is a temporary adjustment of the lever arms away from the stops, with the result of a temporary enlargement of the roller gap.
