Definitions

  • the invention relates to a pair of draw rollers of a web-fed rotary printing press, between the rollers of which a single-layer or multi-layer web is guided according to the preamble of claim 1.
  • DE 42 10 777 C2 describes a pair of drawing rollers of a web-fed rotary printing press between the rollers of which a web is guided. These rollers are connected to one another via a differential gear in order to adapt a peripheral speed of the rollers to changes in the thickness of the web.
  • a disadvantage of this pair of traction rollers is that a complex adjustment mechanism is provided for changing the peripheral speed.
  • DE 42 23 900 C2 discloses a pull roller for changing the web tension.
  • This roller has a jacket which can be changed circumferentially by a pressure medium.
  • the invention has for its object to provide a pair of pull rollers with variable peripheral speed with simple means.
  • Circumferential speed of two rollers of a pair of pull rollers no complex adjustment gear or adjustable individual drives are necessary.
  • an axial spacing of the pair of traction rollers according to the invention is changed in a simple manner, thus changing the peripheral speed of the rollers.
  • This change in circumferential speed can take place continuously and in different ways across the width of the web.
  • a contact pressure of transport elements to the web can be set continuously and differently as viewed across the width of the web. When the peripheral speed is adjusted, the contact pressure remains constant. If the tread of a transport element is divided in two, it can be replaced without dismantling the roller.
  • the pair of pull rollers according to the invention is shown in the drawing and is described in more detail below.
  • a pair of draw rollers 1 of a web-fed rotary printing press consists of two rollers 2, 3 between which a single or multi-layer web 4 is conveyed.
  • the two rollers 2, 3 are constructed identically in the exemplary embodiment.
  • Each roller 2, 3 has a cylindrical tube-like bale 6 with a diameter D2, D3, z.
  • On each roll neck 9, 11 is as a transport element 10, for. B. a transport wheel 13 attached to the right and left of the bale 6 by means of a feather key 14 and a clamping ring 16.
  • the roller journals 9, 11 are in pivotable bearing arms 17 by means of roller bearings 18, for.
  • a two-channel rotary inlet 27 is arranged on each of the opposite roller journals 9 and is connected to the two transport wheels 13 of a roller 2, 3 by means of two lines 28, 29.
  • the bearing arms 17 of the rollers 2, 3 are constructed identically and are each pivotably attached to a first end 33 by means of a bolt 31 on an inside of the side frame 26, 32.
  • a second end 34 of the bearing arm 17 is fork-shaped and provided with a pivotable threaded nut 36.
  • the bearing 38 of the adjusting spindle 37 consists of a frame-fixed pin 39, which is provided with two mutually perpendicular slots 41, 42 . One of these two slots 41 is parallel to the adjusting spindle 37 slightly wider, z.
  • each roller 2, 3 with its own adjusting spindle 37. This is particularly the case if only one of the two rollers 2, 3 is equipped with elastic transport elements 10, 13.
  • the transport elements 10, 13 are torque-transmitting in the circumferential direction and are elastic, that is to say flexible, in the radial direction.
  • the transport wheels 13 executed in the example each consist essentially of a hub 46, a compensating ring 47 and a transport ring 48.
  • the hub 46 is torsionally rigid by means of the feather key 14 and the clamping ring 16, but axially displaceable on the associated roller journal 9 when the clamping ring 16 is released 11 clamped.
  • the compensating ring 47 is attached in the form of a hose, for. B. vulcanized. This compensating ring 47 transmits torques in the circumferential direction and is designed to be elastic in the radial direction, ie compressible.
  • a hose wall 49 of the compensating ring 47 is reinforced with inserts, not shown.
  • a pressure chamber 51 which can be acted upon by pressure medium, for example compressed air, hydraulic fluid or polyethylene foam, is arranged in an interior of the compensating ring 47.
  • This pressure chamber 51 is by means of a bore 52 with the line 28, 29 and thus with the associated rotary lead 27 connected.
  • a pressure control valve (not shown) for setting a pressure of the pressure medium in the respective pressure chamber 51 is provided in a feed line 53, 54 to the rotary inlet 27 for each channel.
  • a common pressure control valve for all channels. These pressure control valves can also be controlled remotely using a computer.
  • the compensation ring 47 can also consist of an elastomer, for example. It is also possible to mount the transport ring 48 by means of radially acting springs which act both on an inner side of the transport ring 48 and on an outer side of the hub 46. It is also conceivable to form the transport ring 48 from an elastomer and to dispense with the compensating ring 47.
  • The, for example, two-part transport ring 48 is fastened on the compensating ring 47 by means of two clamping rings 56, 57.
  • the clamping rings 56, 57 are provided with a cone-like collar 58, 59, which interact with bevelled side surfaces 61, 62 of the transport ring 48 in a frictionally locking manner in the circumferential direction and in a positive manner in the radial direction.
  • the two clamping rings 56, 57 are clamped in the axial direction by means of threaded screws 63 reaching through the compensating ring 47.
  • the transport ring 48 is provided with a running surface 64 in the present example.
  • an outer surface 66 of the bale 6 of the rollers 2, 3 is also possible to design an outer surface 66 of the bale 6 of the rollers 2, 3 to be elastic in the radial direction and to transmit torques in the circumferential direction.
  • a sleeve 67, z. B. a steel or CFRP tube is provided, which is mounted on the continuous shaft 12 forming the roll neck 9, 11 by means of one or more compensating elements.
  • these compensating elements can consist of hoses to which pressure medium can be applied or of the transport wheels 13 (FIG. 4).
  • an annular hose, for. B. a compensating ring 47 may be attached or a continuous tubular hose may be provided.
  • an elastomer can be vulcanized in between the sleeve 67 and the shaft 12 or radially acting springs can be arranged.
  • the shaft 12 can only be coated with an elastomer and the sleeve 67 can be dispensed with.
  • the operation of the pair of pull rollers 1 according to the invention is as follows: Between the drive elements, e.g. B. the transport wheels 13, the web 4 is guided. For this purpose, the pressure chamber 51 of the compensating ring 47 is acted upon by a pressure medium, as a result of which the web 4 is held between the transport wheels 13 with a defined pressure, which is independent of a center distance a of the rollers 2, 3 or a thickness of the web 4. The rollers 2, 3 with the transport wheels 13 fastened thereon are driven via the two drive wheels 21, 22 and the web 4 is transported.
  • the sleeve 67 is shifted from its position concentric with the roll pins 9, 11 into an eccentric position by reducing the center distance a of the two rollers 2, 3, and thus reduces its peripheral speed.
  • the circumferential speed of roller 2 with "fixed" diameter remains constant when the axial spacing a of the two rollers 2, 3 changes, while the circumferential speed of roller 3 changes with elastic transport elements.
  • the two rollers 2, 3 are not in a positive drive connection, but only the roller 3 with a variable diameter is driven in a positive manner.
