Definitions

  • the above invention relates to a device for adjusting a compensating cylinder in a printing press.
  • each printing unit is assigned at least one compensating cylinder of this type, which is mounted such that it can be adjusted in height and can assume an upper maximum position or a lower maximum position relative to the fixed machine frame of the rotary printing press.
  • a known rotary drive is provided which is driven by a controllable motor, for example a direct current motor, which acts on vertically arranged threaded spindles which are arranged parallel to one another and with. the hubs of the horizontally arranged compensating cylinder are operatively connected.
  • feed chains are provided which are arranged in the longitudinal direction on both sides of the machine frame of the rotary printing machine. These chains are led over sprockets and are in regular intervals. connected to each other via crossbars. If necessary, the beginning of the paper web to be drawn in is attached to these crossbars in order to convey them through the entire printing press. For design reasons, two of the chain wheels mentioned above must be provided above the compensating cylinder of the corresponding printing unit, which is in the upper end position.
  • this compensating cylinder is normally not in its maximum upper end position, but in an intermediate position, or even in a position near the lower cylinder position, it was found in the past that considerable difficulties in paper handling occurred in this machine part.
  • the paper web the beginning of which is connected to the crossbar of the parallel feed chains, is first conveyed vertically upwards and thus follows the aligned path of the feed chain in order to then carry out a downward movement again.
  • the object of the above invention is to propose a device with which it is possible to avoid the disadvantages of the prior art, and to ensure that the paper web is properly guided over the compensating roller, also near the reversing wheels of the feeder chains, and that Possibility to create, the time required for the paper feed significantly reduced in rotary printing presses.
  • the object according to the invention is achieved in that the device for adjusting the compensating cylinder is assigned a drive device which can be operated in overdrive or in creep speed.
  • feeding chains 7 are provided, which are provided by Sprockets 8, 9, 10, 11, 12, 13, 14 and 15 are driven and guided.
  • the paper web 1 is indicated by a solid line, while the chain 7 is shown by a chain line.
  • the feed chains 7 arranged in parallel have transverse bars 16 at intervals, to which the beginning of the paper tape 1 to be drawn in can be attached so that the paper tape 1 can thus be drawn in by the rotary printing machine.
  • the compensating cylinder 4 is arranged to slide up and down (arrows f) and, advantageously, a limit switch 17 is provided to determine the maximum upper end position, whereas another limit switch 18 is provided to determine the maximum lower end position.
  • the pure compensating movement of the cylinder 4 takes place via a rotary drive, by means of which the cylinder 4 is driven during the compensating chamfer at a feed rate of approximately 1 mm / s. While the compensating movement in the event of register errors in the fed paper tape 1 can be solved perfectly by the height-displaceable (arrow f) of the compensating cylinder 4 with the aid of the known drive device, it has proven to be a major disadvantage that the paper tape 1 attached to one of the above-mentioned cross bars 16 was attached and is guided over the chains 7 through the individual printing units of the machine, in the case of a compensating roller 4, which is arranged in an intermediate position - as shown, for example, in FIG.
  • the balance cylinder 4 is in operative connection with its hubs 19 with threaded spindles 20.
  • the threaded spindles 20 are arranged in parallel and are provided at each cylinder end 4. Furthermore, the threaded spindles 20 have on their upper side a ring gear 21 which is operatively connected to a corresponding gear wheel 22 which is driven via a horizontal drive shaft 23.
  • a controllable precision motor 24, for example of the “SLO-SYN” type, is provided in a manner known per se for moving the cylinder 4 for the purpose of eliminating “register errors” between the paper tape 1 and printing unit.
  • the shaft 25 of the motor 24 is, for example, at 60 At this speed, a gearwheel 26 is rotated, which is fixedly connected to the shaft of the motor 24 and, via the gearwheel 26, the rotational movement is transmitted to a further gearwheel 27, which at the same time has a toothed spur gear 28.
  • the gear 27 is rotatably supported using ball bearings 29 through a pipe socket 30 which is rotatably arranged with the interposition of further ball bearings 31 on a shaft 32 which in turn, with the interposition of Ball bearings 33 is received by the machine frame 6.
  • a pipe socket 30 Radially projecting from the pipe socket 30 are pins 34 which receive satellite wheels 35, which are in operative connection with the spur gear ring 28 which forms the planet gear.
  • a further motor 37 is provided according to the invention, for example a conventional three-phase motor, for example with 1500 Revolutions / min is driven.
  • This motor is advantageously equipped with a self-braking device (brake motor).
  • the output shaft 38 of the motor 37 has a gear 39 arranged in operative connection with the external toothing 40 at the end of the pipe socket 30 which supports the satellite wheels 35.
  • the operation of the device according to the invention is as follows: by operation. the motor 24 is transmitted via the gear 26, the ring gear 27, the spur gear 28, the satellite wheels 24, the ring gear 36 and the gear 22, on the ring gear 21 of the associated threaded spindle 20, a rotary movement which makes it possible to lift the compensating cylinder or lower. This is done with the greatest accuracy and e.g. with a feed movement of 1 mm / s.
  • the compensating cylinder 4 is located in the vicinity of the chain deflection wheels 11 and 12, which prevents the paper tape 1 that is drawn into the machine by the chains 7 from becoming entangled in an uncontrollable manner in the form of irregular belt loops.
  • the compensating cylinder 4 is lowered again at high speed, together with the drawn-in paper tape 1, which rests on the upper side of the cylinder 4.
  • the motor 37 is advantageously equipped with an automatic braking device 50 (braking motor), as a result of which a drive means is made available which is brought to a standstill quickly and precisely by means of simple control means.
