Definitions

  • the invention relates to a sheet delivery device, in particular for small offset presses, the sheet being detached from a printing cylinder and running into the nip of transport rollers rolling on one another, while guide rollers in the area of the sheet delivery device are assigned to the printing cylinder for the rear region of the sheet to be removed.
  • Sheet delivery devices are used in small offset machines, but also in at least a similar design in devices or devices for copying, duplicating or printing for office or other commercial purposes.
  • the known prior art has disadvantages, particularly with regard to handling and adjustability.
  • the format width can usually only be set when the machine is at a standstill, and the transport rollers, which are usually designed as profile and pressure rollers (due to their own weight), can only be adjusted individually in the longitudinal direction of the cylinder, although the contact pressure between profile and pressure rollers cannot be adjusted is adjustable and therefore cannot be adapted to the different types of paper.
  • This sheet delivery device is characterized above all by an extremely compact and clear construction. A major advantage is ultimately that all setting and adjustment work can be carried out even when the machine is in operation.
  • a sheet 5 to be printed is separated from the stack 1 and fed to a printing cylinder 3 via a feed device 2.
  • the transfer of the printed image takes place in the gap between the latter and a rubber cylinder 4.
  • the printed sheet 5 is then taken over by a sheet delivery device 6 and fed to a delivery stack 7.
  • the rubber cylinder 4 receives the print image from a plate cylinder 8 in front of it, which receives the printing ink via an application roller 9 which is in contact with an inking and dampening unit 10, 11.
  • the machine receives the corresponding commands from the machine operator via the control panel 12.
  • Blanket washing device 61, film feed and etching device 62, 63 are further essential components of the machine.
  • FIG. 2 now shows, in an enlarged representation, the sheet delivery device 6 according to the invention associated with the printing cylinder 3.
  • a stripper 13 is provided which, after its release by the sheet gripper 14, releases the sheet 5 from the printing cylinder 3 and supplies downstream transport rollers 21, 22.
  • the wiper 13 consisting of a plurality of wiper fingers 15 distributed over the machine width in a corresponding arrangement is fastened to the side walls 17, 18 of the machine via fastening screws 19 with its rail 16 carrying these wiper fingers 15 (FIG. 3).
  • the rear area of the sheet 5 is held in contact with the printing cylinder 3 by means of a guide roller 20 resting on the printing cylinder 3 until the transfer by the transport rollers 21, 22 has taken place.
  • the latter are cylindrical rubber rollers 21 assigned to the left and right side of the sheet, as viewed over the sheet width, and to them with a certain contact pressure employed pressure rollers 22 are formed.
  • the contact pressure can be set via a device to be described in more detail later.
  • the cylindrical rubber roller 21 is connected downstream of a guide plate 23 arranged on the left and right side, which is shaped in such a way that the sheet 5 to be laid out has a slight curvature, so that its internal stability is increased in order to make its further path to the delivery stack 7 more trouble-free shape.
  • Guide roller 20 and pressure roller 22 are mounted on a support element 24 designed as an elongated bearing block, which is displaceable in the axial direction on a flattened round axis 25 and can be fixed by means of a toggle screw 26.
  • the flattened rotary axis 25 is fastened to the side walls 17, 18 of the machine by fastening screws 27.
  • the support element 24 is supported with its fork-shaped projection 28 on a further axis 29, the storage of which is also carried out by means of fastening screws 27 on the two side walls 17, 18.
  • Each guide roller 20 is also rotatably mounted on a lever 31, which in turn can be pivoted about a bearing pin 32 of the support element 24 and is spring-supported on the latter via compression spring 33, guide pin 34 and nut 35 with the associated lock nut 30, in order thereby to be able to be applied with a preselectable pressing force on To apply pressure cylinder 3.
  • the pressure roller 22 is also mounted on the support element 24 by means of an axle pin 36 and a lever 37, the other end of which is connected to the support element 24 via a bearing pin 38.
  • a guided in a bore 39 of the support member 24 bolt 40 on the a compression spring 41 acts, the contact pressure is transmitted to the contact roller 22 via a further lever 60 connected to the bearing pin 38.
  • the contact pressure can be varied by means of an adjusting screw 42 acting on the compression spring 41 with a predetermined adjustment range.
  • the setting range includes, for example, less than one screw revolution.
  • a protective shield 44 is provided between the toggle screw 26 and the adjusting screw 42 and the area of the sheet delivery device 6 facing the pressure cylinder 3. This maintains the free accessibility of the aforementioned adjustment elements.
  • Rubber roller 21 and guide plate 23 are connected to the support element 24 via a bracket 45. They are thus laterally adjusted simultaneously with the pressure roller 22. Baffle 23 and rubber roller 21 can also be adjusted laterally relative to the pressure roller 22 by means of knurled nuts 46, which act on a tab 43 of the bracket 45. As can be seen from FIG. 4, the knurled nuts 46 are screwed onto a threaded pin 47 which engages in a threaded bore 48 of the support element 24.
  • the bracket 45 is detachably attached to the lower flattened side 49 of the support element 24 and correspondingly laterally displaceable and continues to encompass the rubber roller 21.
  • the latter with a slight sliding fit, is mounted on a drive shaft 50 equipped with a longitudinal groove 57 and can be axially displaced slightly due to the driving connection with the bracket 45.
  • the drive shaft 50 is supported by ball bearings 51 in axle brackets 52, which are each on the two Side walls 17, 18 are fastened via fastening screws 53.
  • a gear 54 which is mounted on the drive shaft 50 in a rotationally fixed manner, conveys the rotary movement via further gear wheels 55, 56 of the drive chain.
  • the assigned gear 55 is rotatably mounted on a bearing pin 59 held on the side wall 18 by means of fastening screws 58.
