Definitions

  • the invention relates to a method and a device for accelerated transport of sheets to a sheet-processing machine, in particular printing machine, wherein the sheets are aligned transversely and obliquely in the transport path in and against the sheet transport direction.
  • This device consists essentially of a reciprocating driven base support having a mechanical holding device, which can be adjusted via actuators relative to the base support in the transport plane. The adjustment takes place on the basis of position sensors which detect the sheet edge and, in the event of deviation from a desired position, send control signals to the actuators which actuate the holding device in such a way that the sheets can be aligned transversely and obliquely in or against the transport direction of the base carrier ,
  • the holding device itself consists of a format-width terminal strip, which cooperates with a plate support. The holding device, the plates are fed, so to speak, from behind and passed through in the transfer to a further transport device in the waiting position through the nip.
  • This device is preferably suitable for low feed rates.
  • the object of the invention is to provide a method or a sheet transport or acceleration device which is particularly suitable for high feed rates.
  • a particular advantage of the invention is the simultaneous or independent control of a guided in parallel rails support for the gripper device.
  • a held in the gripper device sheet can be accelerated with simultaneous control of the intended linear motors in the sheet transport direction to z. B. to accelerate the bow on the speed of the onward transport system and also to correct late bow.
  • An independent control leads to a Schränk Gay of the carrier and serves the oblique arc correction.
  • a lateral adjustment of the gripper device relative to the carrier is used for lateral alignment, preferably by means of a parallelogram-like adjustment.
  • a simple solution is z. B. a mechanical Steuerrollen- / curve device.
  • the Greiferö Stamms- or -sch thoroughlygraphy preferably takes place via a mechanical control, but alternatively, a suction pad solution is advantageous.
  • Other inventive embodiments such as. As an angular adjustment of the feed device with respect to the further transport device for the purpose of the sheet thickness adjustment, are described in the subclaims. An embodiment of the invention is illustrated in the drawings and will be described below.
  • a sheet 7 processing machine As a printing press 1, has a feeder 2, at least one printing unit 3 or 4 and a boom 6 on.
  • the sheets 7 are removed from a stack of sheets 8 and isolated or scaly fed via a feed table 9 of a sheet feeder 27, which accelerates the sheet 7 passes to the printing units 3 and 4.
  • These contain in a known manner in each case a plate cylinder 11, 12.
  • the plate cylinder 11 and 12 each have a device 13, 14 for attaching flexible printing plates.
  • each plate cylinder 11, 12 is associated with a device 16, 17 for the semi-automatic or fully automatic printing plate change.
  • the sheet stack 8 rests on a controllably liftable stacking plate 10.
  • the removal of the sheet 7 takes place from the top of the sheet stack 8 by means of a so-called suction head 18, which, inter alia, a number of lifting and Schleppsaugern 19, 21 for the separation of the sheet 7 has.
  • blowing devices 22 are provided for loosening the upper sheet layers and sensing elements 23 for stack tracking.
  • a number of lateral and rear stops 24 are provided for aligning the sheet stack 8, in particular the upper sheet 7 of the sheet pile 8.
  • a sheet transport or acceleration system 27 between the feed table 9 and the feed cylinder 26 is arranged.
  • the sheet transport or acceleration system 27 consists essentially of two rails 28, 29 arranged in parallel in the sheet transport direction, each of which has a carriage 31, 32 guided thereon, with which it forms a respective drive, preferably an electromagnetic linear drive.
  • the drives 28, 31; 29, 32 are simultaneously and independently controllable.
  • Both carriages 31, 32 are each via a hinge connection 33; 34 connected to a gripper device 37, preferably with a gripper bar 38, the mechanically operable gripper 39 carries.
  • the gripper bar 38 is arranged laterally displaceable in the region of the carriages 31, 32 in the manner of a parallelogram.
  • the hinge connection 33, 34 are each formed as an eccentric coupling, wherein in each case a first pin 41 is arranged on the carriage 31 and a second pin 42 is arranged on the gripper bar 37 and both pins 41, 42 are connected by means of a coupling 43.
  • a rotatably mounted control roller 44 is provided, which cooperates with an adjustable control cam preferably in the form of a guide rail 46.
  • the guide rail 46 is arranged to be stationary parallel to the sheet transport direction and by means of an actuator 47, z.
  • an actuator 47, z As a linear motor or actuator, mounted transversely to the sheet transport direction adjustable.
  • a spring-loaded counter-roller 49 is provided, whose energy storage 51 is supported on an abutment 52 which is fixed to the gripper bar 38.
  • the guide rail 46 is always located between the control roller 44 and the counter roller 49th
  • the actuator 47 is connected to a control computer 54 of the sheet-processing machine and performs in lateral position deviations of the sheet correction movements, which cause the guide rail 46 is moved transversely to the sheet transport direction. This shift causes by the contact of the control roller 44 with the guides 46 that the gripper bar 38 and thus also held in the grippers 39 Sheet 7 performs a lateral correction movement.
  • the guide rail 46 extends over the entire transport path from the feed table 9 to the further transport device 26, z. B. the feed cylinder. By this measure, a large time window for sheet alignment is available.
  • a gripper shaft 53 carrying the grippers 39 is mounted pivotably on the gripper bar 38.
  • a control roller 58 is arranged, which cooperates with a clock-wise switchable guide rail 59. This is arranged via two pivotally mounted on a side frame coupling 61, 62 deflectable parallel.
  • a control roller 63 at the end of the guide rail 59 cooperates with a control cam 64, the z. B. is driven by the feed cylinder 26.
  • the guide rail 59 extends at least over the entire transport and alignment path s of the gripper bar 38.
  • the transport and Ausrichtumble are adjustable depending on the format sensors 55, 56, 57 for detecting the sheet position in the gripper closure of the gripper 39 are arranged on the leading edge and side edge of the sheet.
  • the sensors 55 to 57 are in communication with the control computer 54, which performs a setpoint / actual value comparison and, in the case of possible deviations, sends a setting or correction command to the lateral sheet position control devices, in particular to the actuator 47.
  • the linear drives 28, 31 are controlled in parallel, so that the normal transport speed or acceleration is superimposed on a corresponding acceleration or deceleration.
  • each other sheet support members 66 Arranged spaced from each other sheet support members 66 extend between the end of the feed table 9 and the feed cylinder 26 over the entire transport and Ausrichtrich. These elements support the only detected at its leading edge sheet 7 on the transport route.
  • the support elements 66 designed as rods can have blown air openings 67, in particular for throttled blown air, on their surface in contact with the sheet.
  • the entire transport and Ausrichtrich is arranged in a frame 68 which is arranged angularly adjustable relative to the upstream conveyor table 9, so that a precise change in distance of the gripper 39 to the grippers 69 of the feed cylinder 26, z. B. in the processing of different sheet thicknesses, manually or by a controllable by the control computer 54 servo motor 71 can take place.
  • the sheet position is determined by means of preferably arranged above or above the conveyor line sensors 55 to 57 and optionally on the way to feed cylinder 26 corresponding correction movements initiated, so that the sheet pass without mechanical alignment aids and without stop fit to the rotating feed cylinder 26 can be.
