Definitions

  • the invention relates to a printing unit of a web offset rotary printing press which is suitable for flying plate changes and has at least two printing units which can be set up alternately or simultaneously on a counter-supported printing material web, each consisting of a plate cylinder and a blanket cylinder, which pass through between the blanket cylinders to produce perfecting on the kidney Printing material web are also adjustable against each other.
  • Such a printing unit is known from DE-PS 35 10 822.
  • the common impression cylinder which in this case is not required, is used as the paper guide roller. Touching the impression cylinder can cause the ink to smear on the side of the paper web previously printed by a blanket cylinder.
  • the object of the invention is to further develop a generic printing unit in such a way that smearing of ink is effectively prevented during straight and reverse printing.
  • each blanket cylinder is assigned its own impression cylinder and the two impression cylinders are spaced apart, the way for a contact-free guidance of the substrate web to a downstream printing unit is cleared between the two impression cylinders.
  • the printing unit according to the invention can thus be used both as an impression unit for flying plate changes and as a normal printing unit for the creation of two-color face printing or of a high quality perfecting.
  • a first printing unit of the printing unit according to the invention is composed of a plate cylinder 1, to which an inking unit (not shown) and a dampening unit are assigned, and a blanket cylinder 2 employed on the latter.
  • the blanket cylinder 2 is mounted so that it can either be adjusted against a counter-pressure cylinder 3 or removed from it.
  • a plate cylinder 5 interacts with a blanket cylinder 4 of a second printing unit and is supplied with printing ink and water by an inking unit and dampening unit, not shown.
  • the blanket cylinder 4 is mounted so that it can be adjusted to the first blanket cylinder 2 or to a further impression cylinder 6 or can be removed from both in a central position.
  • the two impression cylinders 3 and 6 are immovably mounted in the machine frame at a distance that allows the unobstructed passage of a printing material web 7 ⁇ also taking into account any vibrations that may occur on the web.
  • the printing material web 7 - as shown in FIG. 1 - is guided around both impression cylinders 3 and 6 in two-color fine printing.
  • the blanket cylinder 4 applies the first printing ink in cooperation with the impression cylinder 6 and the blanket cylinder 2 the second printing ink in cooperation with the impression cylinder 3.
  • By alternately starting one of the blanket cylinders 2, 4 on the associated impression cylinder 3 or 6 see FIGS. 3 and 5), it is possible to produce changing impressions with this web guide.
  • the second blanket cylinder 4 is turned off from the impression cylinder 6 assigned to it and is set against the first blanket cylinder 2.
  • a 7stoff printing substrate web is passed between the two blanket cylinders 2 and 4 and printed on both sides by this in perfecting.
  • the printing material web 7oul is then passed between the two impression cylinders 3 and 6 without contact to a subsequent printing unit or, if no further inks are to be applied, to the other downstream units, such as a drying unit.
  • the transmission described below, shown in FIGS. 2, 4, 6 and 8, is suitable for realizing the types of production described above with a single force introduction point branching off the main drive.
  • the necessary gearwheels arranged in three parallel vertical planes next to each other on the same machine side have been given the same reference numbers as the cylinders on whose shafts they are arranged, and an index corresponding to their plane has been used to distinguish them.
  • the level indicated with a line ⁇ is closest to the end of the cylinder, followed by the levels indicated with two ⁇ and three lines ′′′ to the outside.
  • the gears used are all helical and correspond in their pitch circle diameter to the diameter of the cylinder on whose shaft they are located. In order to enable power transmission in certain gear pairs and to exclude them in others by missing flank contact, some of the wheels have a positive or negative profile shift, which is shown in FIGS. 2, 4, 6 and 8 by a "+" or a "-" Character is expressed.
  • FIGS. 2, 4, 6 and 8 results from a cut according to the cut line shown in FIG. 1 with a subsequent flap into a projection plane.
  • a gearwheel 3 ⁇ arranged on the shaft of the first impression cylinder 3 and a gearwheel 6 ⁇ arranged on the shaft of the second impression cylinder 6 are in constant engagement.
  • a gear wheel 3 ′′′ provided with a negative profile displacement is also freely rotatable, which can be connected to this shaft by a coupling 9.
  • this gear 3 ′′′ meshes with a positive profile shift provided on the shaft of the first blanket cylinder 2 arranged gear 2 ′′′.
  • a further gear 6 ⁇ is freely rotatable, which can be connected to this shaft via a coupling 10.
  • a negative profile shift gear 6 ⁇ stands with Gear shift 4 transported on the shaft of the second blanket cylinder 4.
  • the gear 4 ′′′ which is still freely rotatable on this shaft, can be connected to it by a coupling 11.
  • the gear 4 ⁇ is equipped with a negative profile shift gear 5 ⁇ on the shaft of the plate cylinder 5 in engagement.
  • the blanket cylinder 2 are employed on the impression cylinder 3 and the blanket cylinder 4 on the impression cylinder 6 for two-color fine printing.
  • the power flow is divided into two strands.
  • the upper train drives the counter-pressure cylinder 3 via the gear 3 ⁇ , the closed clutch 9 and the pair of wheels 3 ′′′, 2 ′′′ of the first blanket cylinder 2 and the associated plate cylinder 1 via the pair of wheels 2 ′′′, 1 ′′′ 6 ⁇ first the impression cylinder 6, further via the closed clutch 10 and the pair of wheels 6 ⁇ , 4 ⁇ the second blanket cylinder 4 and the pair of wheels 4 ⁇ , 5 ⁇ the associated plate cylinder 5 driven.
  • a reaction from the shaft of the first rubber blanket cylinder 2 to the shaft of the second rubber blanket cylinder 4 through the meshing gears 2 ′′′ and 4 ′′′ is avoided by the opened clutch 11.
  • the first blanket cylinder 2 is set against the impression cylinder 3 when impressed by the upper printing unit.
  • the second blanket cylinder 4 is in its central position.
  • the power transmission takes place in the upper section of the drive as described in the previous paragraph.
  • only the impression cylinder 6 is driven by the pair of wheels 8, 6 ⁇ .
  • the opened clutch 10 prevents further power transmission. Since no reaction from the shaft of the first blanket cylinder 2 to the shaft of the second blanket cylinder 4 is possible via the opened clutch 11, the lower printing unit stands still and can be prepared for a following impression.
  • the second blanket cylinder 4 is applied to the first blanket cylinder 2 when applying perfecting, the latter remaining in contact with the impression cylinder 3 assigned to it for drive reasons.
  • these cylinders are now driven with the clutch 10 open from the upper drive train via the pair of wheels 2 ′′′, 4 ′′′, the closed clutch 11 and the pair of wheels 4 ⁇ , 5 ⁇ .
  • the impression cylinder 6 runs idle, which is irrelevant due to the distance between the two impression cylinders to the printing material web 7 'passed between them.
  • the gearbox can be built very narrow and can therefore be accommodated on one machine side. Assembly and ease of maintenance have been improved by the couplings placed exclusively on the shaft ends.
