Definitions

  • the present invention relates to a method in applying a cleaning liquid on a paper web in a printing press by means of a rotating applicator roll in an applicator having an applicator housing.
  • the invention also relates to a device for carrying out this method.
  • the applicator roll is applied against a dip roll, which extends down into the cleaning liquid.
  • the applicator roll - in contact with the dip roll - is laterally pushed partly out of the housing into contact with the paper web, and the two rolls are rotated for cleaning liquid transmission to the web.
  • the device Due to the fact that the device includes two rolls and mechanical means for their handling, it is rather complicated and expensive. It is further not protected against printing ink, lint and similar dirt, formed in the printing press during its service.
  • a solution to these problems is according to the invention obtained in that the applicator roll extends down into the cleaning liquid contained in the applicator housing and is pushed out from the housing into contact with the paper web at the transition from an inoperative position into an operative position, a cover otherwise closing the housing herewith being opened.
  • the above mentioned means comprise a support arm, which is intended for pivotal support of the applicator roll and is pivotally connected to the applicator housing bottom, a hydraulic cylinder, that is arranged between a pivotal fastening in the rear part of the housing and the roll, and a lift arm, which is attached to the lower side of the cover, is pivotally attached to a pivot pin in the rear part of the housing and rests against a lift lever extending rearwardly from the support arm.
  • a support arm, a hydraulic cylinder and a lift arm are preferably arranged at each end of the applicator roll.
  • the applicator roll is preferably provided with an internal drive motor for its rotation.
  • Fig 1 is side view, partly in section, of an applicator according to the invention in a closed, inoperative position
  • Fig 2 is a view corresponding to Fig 1 with the applicator in an open, operative position
  • Fig 3 is a top view of a left part of the applicator; all figures are slightly schematical and only show those parts of the applicator which are important for understanding the invention.
  • an applicator shown in the drawings is intended to be mounted in the immediate vicinity of a substantially vertical paper web in a printing press.
  • the purpose of the applicator is to transmit to the paper web a cleaning liquid in the applicator, the liquid being carried by the paper web for cleaning different parts of the printing press.
  • the applicator has a housing, consisting of a beam 1, which can be extruded in one piece of aluminium, and gables 2, of which only a left gable is shown in Fig 3.
  • This housing 1, 2 is liquid tight and is thus intended to contain cleaning liquid up to a certain level.
  • An applicator roll 3 is rotatably arranged in the housing 1, 2.
  • the internal design of the roll 3 appears from Fig 3.
  • Fig 3 shows the left part of the applicator, and the right part has a corresponding design with the exception of a drive arrangement described below.
  • the roll 3 has a cylindrical shell 4, which is rotatable journalled by means of a bearing 6 on a motor house 5 centrally arranged.
  • An electric motor 7, preferably equipped with a reduction gearing, is arranged in the motor house 5.
  • the electric motor 7 can drive the applicator shell 4 via a drive disc 8.
  • the motor house 5 and thus the applicator roll 3 are supported by the housing in a way further described below via an excentrically arranged support pin 9.
  • a support arm 10 (at each end of the housing 1, 2) is pivotally arranged between a pivot pin 11 in the lower part of the beam 1 and the support pin 9.
  • a hydraulic cylinder 12 (at each end of the housing) is pivotally attached with a rear end in the lower, rear part of the beam 1 at 13 and with a piston rod end pivotally attached to the support pin 9.
  • the housing 1, 2 is provided with a completely closing cover 14, the purpose of which is to protect the inner parts of the applicator in an inoperative position against the intrusion of printing ink, lint and similar dirt present in a printing press in service.
  • This cover has to be removed, when the applicator is brought to its operative position according to Fig 2, which can be accomplished by means of the design described below.
  • the cover 14 On its lower side the cover 14 is provided with an arch shaped lift arm 15, which is pivotally attached in the lower, rear part of the beam 1 at a pivot pin 16.
  • the support arm 10 has a lift leg 10', which extends rearwardly and is terminated by a roller 17 in contact with the lift arm 15.
  • the paper web 18 is substantially vertical, but within the scope of the appended claims it is also possible to imagine embodiments of the invention where the paper web is horizontal or moves in some other direction.
