Definitions

  • the invention relates to a pair of pull rollers Web-fed rotary printing press between its rollers single or multi-layer web is guided according to the Preamble of claims 1 and 16.
  • DE 42 23 900 C2 discloses a pull roller for Change in web tension. This roller has one elastically circumferentially changeable by a pressure medium Coat on.
  • the US 24 07 239 A describes a pair of folding rollers, the Center distance can be adapted to a thickness of signatures.
  • the invention is based on the object Pull roller pair with variable peripheral speed to create 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 in the drawing shown 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 have the same structure and each at a first end 33 by means of a Bolt 31 on an inside of the side frame 26, 32 pivotally attached.
  • a second end 34 of the Bearing arm 17 is fork-shaped and with a pivotable threaded nut 36 provided.
  • the bearing 38 of the Adjustment spindle 37 consists of a frame-fixed Pin 39, the two perpendicular to each other Slits 41, 42 is provided.
  • the adjustment spindle 37 is approximate provided with an axially fixed disc 43 in the center, the in the second slot 42 for axially securing the Adjustment spindle 37 with respect to the side frame 26, 32 is arranged.
  • the threaded nuts 36 of the bearing arms 17 and the adjusting spindle 37 interacting therewith are included Right and left hand threads.
  • the Adjustment spindle 37 in the present example Adjustment handle 44 with integrated position indicator. It is also possible to have each roller 2, 3 with its own Adjustment spindle 37 to be provided. This is particularly so then the case if only one of the two rollers 2, 3 with elastic transport elements 10, 13 is equipped.
  • 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. 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 connected to the line 28, 29 and thus to the associated rotary inlet 27 by means of a bore 52.
  • 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.
  • 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.
  • a lateral surface 66 of the bale 6 the rollers 2, 3 elastic in the radial direction and in Circumferential direction to transmit torques.
  • the outer surface 66 of the Bale 6 forming, acting as a transport element 10 Sleeve 67, e.g. B. a steel or CFRP tube provided, those on which form the roll neck 9, 11 continuous shaft 12 by means of one or more Compensating elements is stored.
  • This Compensating elements can as with the already described transport wheels 13 from with pressure medium pressurized hoses or from the transport wheels 13 exist (Fig. 4). This can be done on each side of the sleeve 67 an annular hose, e.g. B.
  • a balance ring 47 attached or a continuous tubular Hose should be provided.
  • sleeve 67 and shaft 12 vulcanized in an elastomer or radially acting springs can be arranged. In the simplest The shaft 12 can only fall with an elastomer be coated and the sleeve 67 are 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.
  • the peripheral speed is of course also possible beyond a nominal circumferential speed enlarge.
