Definitions

  • the invention relates to a clamping and adjusting device for smoothing devices in a storage drum of a sheetfed offset printing machine for optional face or back printing, wherein the smoothing devices of the shaft of the storage drum are pivotally mounted and solved with centrally arranged actuators relative to the jacket of the storage drum , can be adjusted and clamped using clamping elements.
  • a device of this type is described in DF-PS 31 28 947.
  • a device of this type has been described for example in DE-PS 31 28 947.
  • a radial clamping device is arranged in the sheet transfer drum for a printing press within the hollow shaft. It consists of an inner tube that extends over the entire length of the shaft and a second outer tube that is slidably mounted on the inner tube.
  • the two pipes are provided with conical surfaces facing each other. These conical surfaces are set against ball cages arranged in the shaft of the sheet transfer drum.
  • An actuating shaft with a gearwheel is mounted within the inner tube.
  • the suction devices can be pivoted on the shaft of the sheet transfer drum by rotating the gear wheel.
  • a disadvantage of the whole facility is that it is constructed in a rather complicated manner. So is the inner tube with slopes, with one. Heel for storage in the shaft and with a hole for the setting gear and also extends over the length of the entire shaft. Operation is made more difficult by the fact that other operating elements are provided for the clamping than for the adjustment of the suction devices. Finally, considerable forces are required to tension the suction devices. In addition, it is not clearly recognizable when the clamping is sufficient and therefore also safe, ie it is not specified in which position of the conical surfaces the suction devices are securely clamped. The operating path can therefore become very long. The assembly of the entire facility is very expensive.
  • the invention is therefore based on the object to simplify a device of the type described as far as possible, to make it easier to assemble and to rationalize the operation in such a way that only a tool for clamping and adjustment is necessary, the conditions for loosening and loosening being as small as possible Terminals should be unique.
  • FIG. 1 An overview of a storage drum is shown in FIG. 1. Only grippers that are usually present are omitted here.
  • the storage drum consists of a drum casing 1, which forms the sheet guiding surface 2, and is connected to the hollow shaft 4 via a plurality of base bodies 3. Smoothing devices 5 are likewise pivotably mounted on the hollow shaft 4. Support elements 6 are provided for this purpose, which are pivotable relative to the shaft 4. The two middle support elements 6 are secured on the shaft 4 via intermediate elements.
  • a pivot axis 7 is mounted on each of two support elements 6, with which the smoothing devices 5 are firmly connected.
  • a suction air supply 8 for the smoothing devices 5 is arranged.
  • a control gear 9 is connected to the pivot axis 7 on one side A in order to be able to set the smoothing devices 8 in a circumferential movement.
  • the control gear 9 consists of a control cam fixed to the frame and a cam roller connected to the pivot axis 7.
  • the smoothing devices 8 pass through the drum casing 1 in slots 10.
  • Adjustment means for clamping and adjusting the smoothing devices 5 are mounted in the shaft 4.
  • a second hollow shaft 11 is rotatably mounted on the side A with a bearing element 12 in a drive gear Y which is fixedly connected to the shaft 4.
  • the bearing element 12 is provided with an extension 13 which serves as an operating element.
  • two clamping curves 14 are pinned.
  • the clamping panels 14 cooperate with clamping elements 15.
  • the structure of the clamping elements 15 is explained in more detail below in FIG. 4.
  • Each clamping curve 14 is assigned 3 such clamping elements 15.
  • the actuating shaft 16 is located within the hollow shaft 11. It is also provided with an operating element on the side B and is rotatably mounted in the shaft 11.
  • On the side A a bearing 17 is provided, via which the actuating shaft 16 is rotatably mounted within the shaft 4.
  • a gearwheel 18 is seated on the same shaft end.
  • the gearwheel 18 engages in an intermediate gearwheel 19 which in turn engages in a ring gear segment 20.
  • the ring gear segment 20 is attached to a support element 6 for the smoothing devices 5.
  • the intermediate gear 19 is rotatably mounted in the wall of the shaft 4.
  • FIG 2 the arrangement of the adjusting means on the side A of the storage drum is shown in section. In reality, it corresponds to the drive shaft of a printing press.
  • the hollow shaft 4 is supported by a bearing L in the machine frame G and is firmly connected to a drive gear Z.
  • the second hollow shaft 11 is fastened in the bearing element 12 and rotatably supported in the drive gear Z via this.
  • a hexagon socket 21 is provided as an operating element.
  • a hexagon socket 23 is mounted coaxially to the hexagon socket 21 as the operating element of the adjusting shaft 16 in a bearing ring 22.
  • the bearing ring 22 supports the actuating shaft 16 in the second hollow shaft 11 and is firmly connected to the latter.
  • a pointer 24 for displaying the angular position of the actuating shaft 16.
  • the scale is spread several times for better readability. This increases the setting accuracy.
  • a sprung ejector pin 15 is provided within the adjusting shaft 16 as a safety device.
  • the ejection pin 25 is mounted in a bore 26. It is pressed against a retaining ring 28 by a spring 27. In this position, the stop end 29 protrudes into the hexagon socket 21 and on the surface of the extension 13. This ensures that an adjusting key cannot be left in the control elements unintentionally.
  • FIG 3 the storage of the actuating means is shown inside the storage drum.
  • the actuating shaft 16 is mounted in the shaft 4 via a ball bearing 30 and a bearing ring 31.
  • the ball bearing 30 is between the gear 18 and a locking ring 32 on the Secured shaft end of the actuating shaft 16.
  • the gear is pinned to the shaft end.
  • a sealing washer 33 protects the ball bearing 18.
  • the second hollow shaft 11 is mounted on the actuating shaft 16 above a needle cage 34.
  • a clamping curve 16 is pinned on the shaft 11, which is supported on a clamping element 15 in the wall of the shaft 4.
  • the clamping element 15 is supported with an outer active surface on an expansion sleeve 35.
  • the expansion sleeve 35 is pinned on the shaft 4.
  • the expansion sleeve 35 can be divided into a collar 36 and an expansion ring 37.
  • slots 38 are provided as expansion joints.
  • a support element 6 is arranged on the expansion ring 37 and supports the pivot axis 7.
  • the ring gear segment 20 is fastened to a collar 39 on the support element 6.
  • the intermediate gear 19 is arranged on a bearing pin 40.
  • the intermediate gear 19 lies in an opening 41 in the wall of the shaft 4, on the outside of which the bearing pin 40 is fastened.
  • the structure of the clamping elements 15 is explained in more detail in FIG.
  • the clamping elements are constructed in detail from support rollers 42, which are held in a bearing element 44 via bolts 43, a plate spring assembly 45 and a mushroom-shaped intermediate piece 46.
  • the support roller 42 is arranged with the bolt 43, the bearing element 44 and the plate spring assembly 45 in the interior of the cylindrical intermediate piece 46.
  • the entire unit serves as a spacer between the clamping curve 14 and the intermediate ring 6. It is arranged in a longitudinally displaceable manner in a bore 47 in the shaft 4.
  • the support roller 42 By prestressing the plate spring assembly 45, the support roller 42 is always held in contact with the clamping curve 14.
  • the clamping elements 15 When turning the clamping curve 14 from the Tiefla ge T in the high position H, the clamping elements 15 are pressed outwards via the support roller 42.
  • the clamping elements 15 with the spacers 46 abut the expansion sleeve 35.
  • the expansion ring 37 is radially clamped and clamps the support elements 6 mounted on it by movement at the slots 38.
  • the clamping curve 14 can now be designed such that it contains a grid point in the high position H, so that the clamping curve 14 can only be rotated up to a certain point.
  • the overpressure required for this can be allowed because of the plate spring assembly 45.
  • the clamping force can be adjusted via a corresponding selection of the characteristics of the plate spring assembly 45.
  • the clamping forces of the individual clamping elements 15 are mutually supported, so that the bearing of the hollow shaft 11 is not stressed.
  • the operation of the entire facility can be made very simple.
  • a hexagon wrench the active profile of which is matched to the length of the hexagon socket 21, 23
  • the clamping of the smoothing devices 5 is first released by inserting it into the hexagon socket 21 on the extension 13 and rotating the hollow shaft 11. Then the hexagon wrench is brought further into engagement against the ejection pin 25 and with the hexagon socket 23 in the actuating shaft.
  • the entire smoothing device 5 can be adjusted in the circumferential direction of the storage drum by rotating the adjusting shaft 16 with the aid of the gear wheel 18, the intermediate gear wheel 19 and the ring gear segment 20.
  • the hexagon wrench is pressed out via the ejection pin 22.
  • the smoothing device 5 can be clamped again by rotating the hollow shaft 11. In this way, with a single control element, namely the hex key clamping and adjustment the smoothing devices 5 have been done in one operation.
  • the hexagon wrench cannot be left in the shaft 4 by mistake. It is pushed out by the ejection pin 25. This avoids the risk of accidents.
