Definitions

  • the invention relates to a device for the lateral alignment of sheets by means of a convertible side alignment device which conveys the sheets to a stop by means of a suction slide
  • the suction slide being designed as a suction slide with a suction device and having a cam roller which by means of a force of springs acting on the suction slide can be adjusted to a first or second control cam by means of a shift fork, the control cams being arranged in mirror image relative to one another on a drive sleeve, the suction slide with suction cup being movable in the direction of a reversible stop depending on the cam roller bearing on one of the control cams, and the device is slidably provided for right or left stop in the printing machine as required.
  • a device of this type is known from US-A-3 860 233.
  • the sheets to be processed in the machine may be attached to the left or right or to align them to the left or right.
  • a change of the stop side in the machine is particularly necessary if the front or back of a sheet must be printed in register. In this case, the sheet side edge that was chipped when printing on the front must also be chipped when printing on the back.
  • Such a device shows e.g. DE-PS 1 950 305.
  • This device is a side alignment device that can be switched from pull to slide. To switch from pulling to pushing, this side alignment device is provided with interchangeable upper parts, one part being designed as a slide part and the other as a pulling part.
  • Another device (DE-PS 1 278 449) describes a device in which a suction slide is provided on the right and left of the machine. These suction slides are coupled together and are driven together by a curve. To switch from right to left stop, the bow stop and a bow driver attached to the suction slide are exchanged. By moving the curve, the suction slide can be moved in an opposite direction.
  • This device also has the disadvantage that considerable conversion work is required to convert from right to left.
  • the invention is therefore based on the object of creating a device which can be used on the right and left of the printing press without extensive changeover work having to be carried out on the device. Furthermore, the device should be compact, so that it takes up little space in the printing press.
  • the advantage of this device is, in particular, that a printing press only has to be provided with a side alignment device. It is also advantageous that the change from right to left stop can be done in just two easy steps.
  • the device is designed such that after the sheets have been aligned on the side stop, i.e. after the suction movement is zero, blowing air can be supplied to the suction. This ensures a safe separation between the suction cup and the sheet.
  • the side alignment device 1 essentially consists of a housing 2, a drive sleeve 3 mounted in the housing 2, which is provided with control cams 4, 5 which are arranged in mirror image to one another, a suction pipe 6 on which a suction slide 7 is slidably mounted and a suction cup 8 carries and a removable stop 9, which can be inserted into corresponding bores 10 of the housing 2. Furthermore, the housing 2 has a suction air chamber 11 which can be acted upon with suction air via an air connection 12. The suction pipe 6 is connected to the suction air chamber 11 via a suction air line 13 and a valve.
  • the drive sleeve 3 carrying the control cams 4, 5 is mounted in the housing 2 in radial bearings 15, 16.
  • a shift fork 18 which can be actuated via an eccentric 17 is provided, between the claws 19, 20 of which springs 21, 22 are arranged which are pushed over the suction tube 6 and which counter the suction slide 7, which is provided with a cam roller 23, depending on the position of the shift fork 18 press a control curve 4 or 5.
  • the control cam 4 is, as shown, on its side opposite the cam roller 23 with a Provided recess 14 and acts with the suction air chamber 11 as a valve.
  • the recess 14 is arranged so that the suction 8 can be acted upon by suction air during its movement in the direction of the stop 9. So that the control curve 4 is tight against the suction air chamber 11, a compression spring 24 with a spring constant that is greater than the spring constant of the springs (21, 22) is arranged so that it drives the drive sleeve 3 and thus the control curve 4 as in Fig. 1 shown presses to the left.
  • An axial bearing 25 is provided between the housing 2 and the control cam 5.
  • the device If the device is to be used on the opposite side of the machine, it is moved to its required position, the stop 9 is moved into the existing pipes 10 and the shift fork 18 is adjusted with the eccentric 12 so that the spring 21 is in effect and the spring 22 is set from their effect.
  • the cam roller is now on curve 5.
  • the alignment process is then carried out in the same way as previously described.
  • the mirror-inverted arrangement of the control cams 4 ensures that both the suction movement and the suction air supply for right and left stop occur at the same time. A change of curves or the like is not necessary.
  • control curve 5 like the control curve 4, could be designed as a valve slide, so that blown air can also be blown into the suction pipe 6 with an additional air line and air chamber.
