Definitions

  • the invention relates to a variable-format printing unit or a format variable slot for offset printing, with one Machine frame, in which an impression cylinder, a blanket cylinder and a plate cylinder are stored and with drive means for the mentioned cylinders.
  • the impression cylinder, the blanket cylinder, the plate cylinder and the inking unit respectively with its own drive, for example its own engine Mistake.
  • its own drive for example its own engine Mistake.
  • the speeds of the blanket cylinder and the plate cylinder are but comparatively high, as suitable engines are expensive.
  • a drive which the entire slot including the format parts and the Farbwerks drives.
  • the mentioned cylinders and the inking unit are thus driven together by a single drive. If the printing length changed, so must on the mentioned Air axes drive wheels are changed so the perimeters the pitch circles of the drive wheels again correspond to the pressure length. The manufacturing cost of such a printing unit are comparatively low.
  • the disadvantage is the high Set-up time in a format change, as mentioned drive wheels have to be changed.
  • the invention is based on the object, printing unit or a Insert of the type mentioned, in a short Setup time is cheaper to produce at the same time.
  • the task is in a generic printing unit or slot solved by the blanket cylinder and the plate cylinder driven by its own common drive are.
  • the impression cylinder and the inking unit become independent from the blanket cylinder and plate cylinder via a motor or a gearbox driven.
  • the drive means are in their Manufacture thus much cheaper than the above embodiment, in which each cylinder and the Have inking own drive.
  • the set-up time is at the same time comparatively low, since with a change of Print image length no drive wheels need to be changed.
  • the plate cylinder and the blanket cylinder via a coupling gear are driven.
  • all drive wheels remain engaged.
  • a change of the print image length is so easy.
  • the Coupling gear is a transmission with two pontics, where one of the two intermediate links is driven.
  • the drive takes place here, for example, with a motor that with a the intermediate links is in operative connection.
  • This engine preferably has a fixed motor axis.
  • the coupling gear a gear transmission with four gears, wherein two of these gears are each driven on one of the two Cylinders are attached.
  • FIG. 1 shows a side view of a drawer 1, the a plate cylinder 23 and a blanket cylinder 24, each on two bearing plates 3 and 25 one further are stored not shown here machine frame.
  • the Plate cylinder 23 and the blanket cylinder 24 are of a common drive 4 driven.
  • slot 1 is also a counter-pressure cylinder 42 stored, but here only indicated by dashed lines.
  • This impression cylinder 42 is driven by a further drive 45, the also indicated only by dashed lines.
  • an inking unit 43 which may be formed as usual and with the plate cylinder 23 is colored.
  • the plate cylinder 23 has a carrier shaft 39 and a format part 38.
  • the blanket cylinder 24 is similarly constructed and has a carrier shaft 37 and a format part 36.
  • the plate cylinder 23 is here also slidably mounted in guide slots 47.
  • FIG. 1 shows this Printing unit 1 with a setting of 20 "format
  • FIG. 2 shows the insert 1 for a format of 28 ".
  • the plate cylinder 23 and the blanket cylinder 24 When converting from one format to another the plate cylinder 23 and the blanket cylinder 24 replaced. In addition, the speeds of these two cylinders are adjusted. Also conceivable here is an embodiment in which the Format parts 36 and 38 are formed as sleeves, which on an air shaft are pushed. At a format change will be then only exchanged these sleeve-shaped format parts. In the present embodiment form at Plate cylinder 23 and the blanket cylinder 24, the carrier waves 37 and 39 with the format part 36 and 38, however, a solid unit.
  • the carrier shafts 37 and 39 are respectively at their ends Rolling 35 on which between a lower bearing shell 32nd and an upper bearing shell 33 is fixed.
  • the upper bearing shell 33 is folded away, so that the plate cylinder 23 and 24 each from above into the corresponding two lower bearing shells 32 are used.
  • the carrier shaft 39 of the plate cylinder 23 is according to Figure 3 at the right end over a Coupling 48 connected to a drive shaft 6 for rotary transmission.
  • the carrier shaft 37 of the blanket cylinder 24 is also connected via a coupling 48 with a drive shaft 7.
  • the clutches 48 and the drive shafts 6 and 7 are respectively mounted with a roller bearing 49 in a plate 15 and 16 respectively. These plates 15 and 16 are each on the outside of the Bearing plate 3 is arranged.
  • the plate cylinder 23 and the blanket cylinder 24 each with a plate 28 and 50 and a Bearing journals 29 and 51 slidably mounted.
  • the journals 29 and 51 protrude through the guide slot 14 and 47, respectively therethrough.
  • a clamping plate 30 connects the journal each 29 and 51 with the plate 28 and 50, respectively.
  • the drive 4 is as already mentioned only for the plate cylinder 23 and the blanket cylinder 24 is provided. These Both cylinders thus have their own common drive.
  • the impression cylinder 42 and the inking unit 43 have own drives 45 and 46. Conceivable here is also a separate common drive for the impression cylinder 42 and the inking unit 43.
  • the drive 4 has a motor 2 with a pinion 5, the meshes with a first idler 10.
  • the engine 2 is fixed connected to the bearing plate 3.
  • the speed of the motor 5 is adjustable. When converting to a different print length the motor 5 remains in its position while its speed adapted to the new print image length.
  • the first intermediate 10 meshes with a second intermediate 11 and with a gear 9, as shown in FIG. 4 on the drive shaft 6 is attached.
  • the second intermediate 11 meshes with a gear 12, the rotation on the drive shaft. 7 sitting.
  • this gear 12 is drawn from drawing Reasons omitted.
  • the four gears 9, 10, 11 and 12 form a transmission 8, which is driven by the engine 2.
  • the engagement of the pinion 5 on the gear 10 and the gears 9, 10, 11th and 12 among each other remains even when changing the print image length receive.
  • the drive 4 has a coupling linkage 17 with a first Lever 18, a second lever 19 and an intermediate lever 20th
  • the intermediate lever 20 is connected via a first pivot 21 with the first lever 18 and a pivot 22 with the second lever 19 connected. These hinges 21 and 22 are through Axles 52 and 53 formed with the first intermediate 10th or the second intermediate 11 are connected.
  • the coupling linkage 17 holds the two intermediate wheels 10 and 11 together and with the gears 9 and 12 in engagement. This procedure is also maintained when, as mentioned, the print length will be changed. If the printing length according to Figures 1 and 2 changed from 20 "to 28", the distance between increases the drive shafts 6 and 17. Here, the plate cylinder 23 in the guide slot 13 and the blanket cylinder 24th moved in the guide slot 14.
  • Conceivable is an embodiment in which instead of the plate cylinder 23 the inking unit 43 is adjusted.
  • Corresponding inking units are known in the art.
  • insert 1 ' are the diameter and correspondingly the peripheries of the plate cylinder 23 and the blanket cylinder 24 larger than the slot 1.
  • the impression cylinder 42 is in both slots 1 and 1 ', however the same and does not need to be replaced.
  • the upper bearing shells 32 are released so that the blanket cylinder 24 and the plate cylinder 23 from the corresponding lower bearing shells 32 are lifted out can.
  • these two cylinders are 23rd and 24 each provided with recessed grips 40.
  • the new cylinders are now used.
  • By axial displacement of the two cylinders 23 and 24 slaughter this with the drive shaft 6 and 7 for torque transmission coupled.
  • By tightening the clamping screws 34 are now the rolling bearings 35 axially fixed.
  • the center distances and adjusted the speeds To the speed of the Adjust plate cylinder 23 and the blanket cylinder 24 must only the speed of the motor 2 are changed. An exchange of drive wheels or the like is not required.
