Definitions

  • the invention relates to a device for format adjustment on sheet guide drums of a printing press, in particular on the storage drum of a sheetfed offset printing press for optional face printing or face and back printing, which has the features of the type according to the preamble of claim 1.
  • Such a device is described and shown in the drawing in DE-OS 34 10 689 using the example of a storage drum in a sheet-fed offset printing press.
  • many elements are required for precise sheet guidance.
  • the sheet is precisely aligned, held and smoothed on a storage drum before turning.
  • Smoothing devices made of suction cups or grippers or also suction cups and grippers are used for this.
  • the position of these smoothing devices in relation to the transport grippers for the sheet must be matched to the format of the sheet to be processed and is therefore to be adjusted when changing the sheet format and also when changing from straight printing to face and back printing, and as a rule regardless of the change the transport and turning gripper.
  • the smoothing devices are arranged on a support element which is pivotally mounted on the drum shaft and can be locked with the drum body in any rotational position by clamping, so that when released Clamping can be carried out continuously.
  • an adjusting device is provided with an externally rotatable adjusting shaft, which is mounted centrally in a hollow shaft assigned to the elements of the clamp, which in turn is mounted concentrically in a hollow (tubular) drum shaft.
  • the actuating shaft has an internal hexagon at the end that leads outwards, so that it can be rotated with a correspondingly profiled tool. With the inner end, the actuating shaft protrudes far beyond the half drum width into the hollow shaft, the pinion attached here meshing with an intermediate gear rotatably mounted in the hollow shaft wall, which meshes with a toothed segment attached to the support element.
  • Such an adjustment device can be operated from the outside, but is complicated to manufacture and assemble. Hollow shafts for the storage of the storage drum result in a weakening of the drum shaft journal.
  • the object of the invention is the design of an externally operable device for format adjustment from a few easily assembled parts, which can be accommodated without significant weakening of the bearing journal.
  • the invention solves this problem by training features according to the characterizing part of claim 1 in connection with a device according to the preamble.
  • a short, thin control shaft is provided eccentrically in a bore with a correspondingly small cross-section in a bearing journal of the drum shaft made of solid material and engages directly with a toothed segment with the pinion fastened on this control shaft. which is arranged on the end face of the support element adjacent to this bearing journal.
  • the bore provided for the mounting of the actuating shaft and a lateral recess in the bearing journal required for the lead-out of the pinion on the actuating shaft do not lead to any noteworthy weakening.
  • a further pinion is fastened on the outwardly directed end of the actuating shaft, which is rotatably mounted in a concentric to the longitudinal axis of the drum shaft on its end face.
  • the features of the invention are suitable for operating the adjusting device by hand as well as for motorized adjustment.
  • a hexagon or the like is provided on the outer end of the actuating shaft in a manner known per se.
  • the pinion arranged on the outer end of the actuating shaft engages in the internal toothing of a pointer ring which is rotatably mounted concentrically to the longitudinal axis of the drum shaft and which cooperates with a fixed format scale.
  • the pinion arranged on the outer end of the actuating shaft engages in a drive pinion concentrically rotatably mounted in the bearing journal of the drum shaft and coupled to an actuator, the housing of which is held on the frame in a machine-fixed manner.
  • the storage drum 1 is supported with the bearing journal 2 of its shaft 3 made of solid material at both ends in the machine frame 4 and can be driven by a gear wheel 5 located in the chain of the drive gearwheels, which is firmly connected to the end face of the bearing journal 2 by screws 6.
  • sheet grippers 7 are arranged in a manner known per se.
  • a support element 8 is infinitely adjustable in the angle of rotation about the longitudinal axis 9 of the drum shaft 3 and, in the set position, can be firmly clamped to the body of the storage drum 1 by a clamping device not shown in the drawing.
  • suction nozzles 10 are shown in FIG. 2, for example, which are arranged opposite the transport grippers 7 in the pit or the drum channel running axially between the support element 8 and the body of the storage drum 1.
  • the mechanism for adjusting the support element 8 relative to the body of the storage drum 1 consists of a Control shaft 11, which is rotatably mounted in an asymmetrical to the central longitudinal axis 9 parallel to this arranged bore of the bearing pin 2.
  • the inner end of this actuating shaft 11 carries a pinion 12 which is rotatable in a lateral recess and which engages with its toothing directly in the inner toothing of a toothed segment 13 which is fastened to the end face of the support element 8 adjacent to the bearing journal 2.
  • the toothed segment 13 extends on the support element 8 over the maximum adjustment range.
  • the outwardly directed end of the actuating shaft 6 passes through the gear wheel 5 and, in the example of FIGS.
  • a hexagon 14 which enables the actuating shaft 11 to be rotated by means of a correspondingly profiled tool.
  • a further pinion 15 is fixed on the adjusting shaft 11, which engages with its toothing in the inner toothing of a pointer ring 16, which is rotatably held concentrically with the central longitudinal axis 9 on the end face of the bearing journal 2 or the gear wheel 5.
  • the pointer ring 16 has on its inside an annular shoulder 17 which engages in a correspondingly profiled annular groove 18 on the end face of the gear wheel 5. With its edge, the pointer ring 16 engages behind head-like thickenings of a plurality of retaining screws 19 distributed around the circumference.
  • a pointer 20 fastened to the pointer ring 16 interacts with a scale 21 formed on the gear wheel 5.
  • This scale is coordinated with the sheet formats that can be processed with the machine.
  • the format setting achieved by rotating the adjusting shaft 11 by means of the hexagon 14 is indicated by the pointer 20 on the scale 21.
  • the pinion 15 arranged on the outer end of the adjusting shaft 11 can thus be used to transmit the driving forces.
  • this pinion 15 is in engagement with a drive pinion 22 which is mounted in the gear wheel 5 so as to be freely rotatable concentrically with the central longitudinal axis 9 and can be coupled to a drive motor 23, for example an electric drive motor.
  • a drive motor 23 for example an electric drive motor.
