Definitions

  • the invention relates to a web guiding element of a newspaper printing press according to the preamble of claim 1.
  • Web guide elements serve to guide the paper webs to be printed from the reel changer area, the so-called roller cellar, via a paper chute into the printing unit area.
  • the web guide elements are usually mounted by hand.
  • first holding devices are attached to the underside of the ceiling construction, which separates the reel changer area from the printing unit area. After mounting the holding elements, the individual guide rollers are attached to the holding elements.
  • auxiliary devices such as cranes or hoists
  • the assembly of the guide rollers can only be accomplished by several auxiliary persons.
  • the guide rollers must be aligned in the holding devices, so that a good printing result can be achieved by a correct guidance of the paper web during the later printing process.
  • the present invention is based on the problem to reduce the assembly work for web guide elements and at the same time to reduce the adjustment effort for the guide rollers.
  • the web guiding element has at least one guide roller which is preassembled in a frame or in a housing. This assembly is inserted as a whole unit in the paper chute and fastened with holding devices on the web guide wall.
  • the execution of the guide roller with frame or housing as an assembly allows the introduction of the web guide element from the printing unit area down into the reel changer area, thereby the use of lifting equipment, such as overhead cranes, is possible. Due to the preassembled structure also eliminates the previous assembly of the guide rollers on the previous fixtures
  • the assembly By attaching the assembly to the web guide wall, which is aligned within the arrangement of the newspaper printing press in the three coordinate directions x, y, and z, the overall alignment effort of the guide rollers is reduced or even avoided. If the frame or the housing is manufactured with low manufacturing tolerances, further guide roll orientation is usually unnecessary since the guide roll is already aligned by the attachment to the web guide wall.
  • the length dimension and the width dimension of the assembly may be less than or equal to the length dimension and the width dimension of the paper well, thereby facilitating the insertion of the assembly into the paper well.
  • the height dimension of the module is preferably greater than or equal to the paper chute height.
  • the distance of the guide rollers can be adjusted from the bottom of the ceiling construction and thus the angle of attack of the paper web can be varied. If the angle of attack of the paper web is perpendicular or nearly perpendicular to the ceiling construction, it is also conceivable to carry out the height dimension of the smaller than the paper chute height.
  • At least one sound-insulating element is arranged for sound insulation between the printing unit area and the reel changer area.
  • This sound insulation between reel changer area and printing unit area is partly country-specific prescribed.
  • the sound-absorbing element can then be mounted on the assembly of the web guide element, whereby the hitherto rather cumbersome mounting of the sound-absorbing element in the paper chute area can be omitted.
  • the sound-absorbing element as one or more frame walls or housing walls of the assembly.
  • the sound-absorbing element may be formed as a holding element of the at least one guide roller and at least absorb parts of the weight of the at least one guide roller.
  • the frame or the housing is formed exclusively of sound insulation elements.
  • the holding devices as pin elements, preferably dowel pins, and / or bores which are connectable to complementary bores and / or pin elements on or in the web guide wall .
  • the frame or the housing in addition to the pin connections a screw or have a similar positive or non-positive connection between the frame and housing and web guide wall.
  • a further advantageous embodiment of the web guide element provides to arrange at least one further holding device on the frame or on the housing of the web guide element and on the underside of the ceiling construction in the reel changer area.
  • a holding device for example, is an angle or a U-shaped rail, with one leg is attached to the frame or on the housing and the other leg is attached to the paper chute or on the ceiling structure.
  • adjusting elements are arranged on the frame or on the housing, with which the orientation of the guide roller is variable. Basically, the correct position of the guide rollers is already made by the attachment of the frame or the housing to the aligned web guide wall. With the adjusting elements, however, a fine adjustment of the guide roller can be made to thereby compensate for tolerances of the frame or the housing.
  • two or more guide rollers may be arranged, wherein the axes of the guide rollers may be offset from each other or arranged in a line.
  • the Fig. 1 shows a sectional view through the area of the paper chute 4 of a newspaper printing press.
  • 4.3 designates the paper chute height.
  • the printing unit area 1 In the upper part of FIG. 1 is the printing unit area 1, in which the printing units of the newspaper printing press stand.
  • a ceiling construction 3 located in the lower part of FIG. 1 the reel changer area 2, in which the paper 8 to be printed is mounted on reelstands.
  • 4 sound insulation elements 5 are mounted in the paper chute, which are mounted here on the wall of the paper chute.
  • the web guide element With the web guide element, one or more paper webs 8 are to be conveyed from the reel changer area 2 via the paper chute 4 into the printing unit area 1 to the printing units.
  • the web guide element consists in this embodiment of a holding device 7, to which two guide rollers 6 are attached here.
  • the holding device 7 When building the newspaper printing machine, the holding device 7 is first attached to the underside of the ceiling structure 3, then the guide rollers 6 mounted on the holding device 7 and aligned.
  • the guide rollers 6 may have a weight of about 80 kilograms, so when installing the guide rollers 6 more people are necessary.
  • the arrow with reference numeral 13 indicates the installation direction of the guide rollers 6 during assembly of the newspaper printing press.
  • the aim of the invention is to reduce the assembly of the web guide elements and at the same time to reduce the adjustment effort for the guide rollers, wherein in the Figures 2 and 3 possible embodiments of a web guiding element are shown.
  • the Fig. 2 shows a sectional view through the paper chute 4 and through the web guide element according to the invention.
  • the web guide element is designed here as a preassembled module 10, which is designed in this embodiment as a housing with four walls 10.4 and 10.5.
  • the width 10.1 and the length of the assembly 10 is adapted to the paper chute width 4.1 and the paper chute length.
  • the assembly 10, to which two guide rollers are fastened to the side walls 10.4 in the lower region, is preferably inserted from the printing unit area 1 into the reel changer area 2 in the direction of arrow 14. This makes it possible to use in the assembly of the web guide element of a ceiling crane in the printing unit area and thus reduce the amount of people involved in the installation.
  • the assembly 10 is secured to the web guide wall 11 with pin members 12.
  • Another advantage of the new web guide element proves to be the direct attachment of the sound insulation elements 5 on the front / rear wall 10.5 of the housing assembly 10. This eliminates the cumbersome mounting of the sound insulation elements 5 in the paper tray. 4
  • the Fig. 3 shows a further sectional view of the web guide element FIG. 2 , wherein the cutting axis passes through the guide axes 6 and along the paper chute length 4.2.
  • 10.3 is the height and with 10.2 the length of the assembly is designated.
  • the attachment 12 can be seen on the web guide wall 11 on the left and on the right.
  • FIG. 3a shows an enlarged view of the in FIG. 3 circled area.
  • the attachment 12 of the assembly or the side wall of the assembly 10.4 is shown with a dowel pin 15 on the web guide wall 11.
  • the web guide element according to the invention can thus be introduced from the printing unit area through the paper chute into the reel changer area, ie in the direction of the acting gravity. An introduction in the opposite direction is also possible. Since the space in the printing unit area is not as tight as in the reel changer area, the use of auxiliary devices is now possible. As a result, the amount of people involved in the assembly and the manual work of the heavy web guide elements can be reduced.
