Definitions

  • the present invention relates to a cleaning device for cleaning the surface of a roller used for processing or transporting a film or a printing medium in a film processing machine or a printing machine, and in particular, a roller cleaning device for cleaning the surface of a roller with a cleaning cloth. It is about.
  • Film processing machines and printing machines are equipped with a large number of rollers for processing or transporting films and print media. Since these rollers are in direct contact with the print media and film, they must always be kept clean. In particular, in a film processing machine, keeping the rollers clean is a condition for performing high-quality film processing. When foreign matter adheres to the surface of the roller, the foreign matter adheres to the film being transported or scratches the film. Further, in precise printing, it is necessary to keep a large number of rollers in contact with a printing medium such as printing paper, cloth, and film clean. In addition, the paper manufacturing equipment used in the paper industry and the cloth production equipment used in the textile industry also use a large number of rollers, and as with printing machines and film processing machines, they must be kept clean. .
  • Patent Document 1 discloses a roller cleaning device that can be used in a printing machine, a film processing machine, and the like.
  • the roller cleaning device of Patent Literature 1 includes components necessary for automatically cleaning the surface of the roller with a cleaning cloth.
  • the cleaning cloth is supplied from the supply unit and is wound up by the winding unit.
  • a pad for pressing the cleaning cloth against the surface of the roller is disposed between the supply unit and the winding unit.
  • the foreign matter adhering to the surface of the roller is not necessarily distributed uniformly on the surface of the roller.
  • Foreign matter adhering to the roller changes the surface properties of the roller.
  • the foreign substance grows gradually and may accumulate thickly.
  • the outer diameter of the roller increases at the portion where the foreign matter adheres.
  • a pad used in the roller cleaning device of Patent Document 1 does not have a structure for escaping from a foreign substance when the cleaning cloth is pressed against the surface of the roller, and thus collides with the foreign substance via the cleaning cloth.
  • the roller cleaning device described in Patent Document 2 uses a blade as a pressing member for a cleaning cloth, and the cleaning cloth is pressed against the surface of the roller by the blade.
  • the whole apparatus is rotatable centering on a rotating shaft.
  • the cleaning cloth is strongly pressed linearly by the blade against the surface of the roller, and then comes into weak contact with the surface so as to cover the surface of the roller.
  • the roller cleaning device of Patent Document 2 has a structure in which the entire roller cleaning device escapes over it.
  • the blade collides with the foreign matter via the cleaning cloth.
  • the blade of the roller cleaning device of Patent Document 2 includes a compression spring inside, and the tip of the blade hits the surface of the roller by the urging force of the compression spring. Since the urging force acts along the width direction of the blade, the compression spring does not expand or contract according to the foreign matter attached to the roller surface.
  • this roller cleaning device structurally increases the mass of the movable part, so that when foreign matter is accumulated thickly or small foreign matter is continuously present, it can follow the shape of the foreign matter and move. I can't do it. For this reason, the roller cleaning device collides with the foreign material against the shape of the foreign material, and the impact of the collision greatly disturbs the rotation of the roller.
  • This roller cleaning device has the same problem as the roller cleaning device of Patent Document 1, and has a problem that the roller cannot be cleaned during product production. Further, the position of the foreign matter accumulated on the surface of the roller is unspecified, and in the structure of this roller cleaning device, the blade cannot escape from the foreign matter at the unspecified position.
  • Patent Document 3 describes a roller cleaning device that can clean a roller without interrupting the production line.
  • the roller cleaning device of Patent Document 3 is similar to the roller cleaning device of Patent Document 1 in that a pad is used as the pressing body, but the width of the cleaning cloth is shorter than the width of the roller. If the contact width between the cleaning cloth and the surface of the roller is small, the influence of foreign matter adhering to the roller surface is reduced. Even if the pad collides with a foreign object, the influence of the cleaning cloth on the rotation of the roller can be reduced if the rotational force of the roller is sufficiently large.
  • Patent Document 3 since the influence of the cleaning cloth on the rotation of the roller depends on the rotational force of the roller, the state of foreign matter on the surface of the roller, and the characteristics of the cleaning cloth, the roller cleaning device of Patent Document 3 is disclosed in Patent Document 1 and Patent Document 2 has the same problem as the roller cleaning device.
  • the inventors have compared the pad type with the cleaning cloth and the surface of the roller as compared with the blade type. It was found that it was difficult to keep the contact state constant over a long period of time.
  • the pad type has a large change with time in the contact state. This is because the contact state between the cleaning cloth and the surface of the roller is determined by the elastic force of the rubber used for the pad, the pressing force of the pad, and the like. The elastic force of rubber changes with time depending on temperature and usage history.
  • the air pressure when used to obtain the contact pressure between the pad and the roller to be cleaned, it is difficult to keep the air pressure at a predetermined constant pressure, which is also an unstable cause.
  • the contact pressure is determined by a mechanical spring. Therefore, the blade type is stable with little change with time in the state where the cleaning cloth and the surface of the roller are in contact with each other.
  • the conventional roller cleaning device has a problem that the frictional resistance between the cleaning cloth and the surface of the roller greatly fluctuates when there is a deviation in the adhesion state of the foreign matter in the circumferential direction or the axial direction of the roller surface. .
  • the conventional roller cleaning device has a structure in which the surface of the roller is wiped by causing a pad or blade to collide with the foreign matter regardless of the attached state of the foreign matter attached to the surface of the roller.
  • the present invention realizes a roller cleaning device in which a change in frictional resistance between the cleaning cloth and the roller surface is reduced even when foreign matter is unevenly attached to the surface of the roller.
