Definitions

  • the invention relates to a device for adjusting pressure rollers or cutting blades on folding structures or turning structures and web guiding elements according to claim 1.
  • the former In printing machines for variable web widths, either the former is shifted, or the printing material are cut before the former into two partial webs and then each directed to the center of the fixed former through turning devices, such as turning bars.
  • the cutting blade and / or the pressure rollers which are employed on non-printed areas of the printing substrate, each to be adjusted to the resulting from the width of the printing material new format.
  • these 16 pressure rollers and up to 3 cutting knives which have to be adjusted to the various formats, with 8 pressure rollers on the front side and 8 pressure rollers on the back side of the printing material web attached to them.
  • the adjustment of these 16 pinch rollers and 3 cutting blades is done today by hand or by 19 adjusting devices, each with its own drive, ie you need to adjust, for example, 19 motors. This results in a high material and adjustment costs.
  • the DE 66877 shows a folding device with two laterally mutually adjustable formers, each associated with a cooperating with a arranged on the funnel entrance cutting roller cutting roller, which is set to the funnel center.
  • a lateral adjustment of the former it must also be possible to adjust the cutting rollers laterally relative to the associated cutting roller. An adjustment is not apparent. The adjustment of the cutting rollers is obviously done manually here.
  • the US Pat. No. 5,328,437 shows a folding device with two laterally adjustable formers. In the area of the funnel nose of each former 11, 12 these flanking folding rollers 26, 27 are provided. These must be adjusted with the assigned funnel.
  • a threaded spindle 36 is provided to adjust the former.
  • the respective folding rollers associated folding rollers are accommodated on a carriage 28 and 29 respectively.
  • the two folding hoppers 11, 12 associated carriage 28, 29 are adjustable by means of an associated threaded spindle 35.
  • the threaded spindles 35, 36 are drivingly connected to each other and simultaneously driven.
  • a handwheel 41 is provided.
  • a synchronous motor may be provided.
  • the threaded spindles 35, 36 contain only the formers or the car associated threaded sections. Cylinder sections which are not to be adjusted and which are accessed by the threaded spindles are not provided.
  • the EP-A 0 457 304 shows a device for the production of bags, in which a web is folded so as to give a tubular shape.
  • cooperating with guides 17 forming rollers 12 are provided which each generate a fold line.
  • the guides 17 are laterally adjustable by means of an associated, driven by a motor threaded spindle 27.
  • the shaping rollers 12 are laterally adjustable by means of an associated, driven by a motor threaded spindle 11. Again, all the threaded spindles 11, 27 associated with organs in the event of actuation of the threaded spindles laterally adjusted. Stationary, accessed by the threaded spindles organs are not provided. Again, the threaded spindles therefore contain only threaded sections. Threadless sections are not needed here and are therefore not provided.
  • the device for adjusting the pressure rollers and / or cutting blade in Falziedten especially at the Falztrichterebene, consists of opposite the pressure rollers and / or cutting blade arranged driven tension rollers or over the web width extending driven tension rollers and consists of at least two threaded spindles, by means of which the pressure rollers and / or the cutting blades are axially displaced, wherein during the axial adjustment a part of the pressure rollers and / or cutting blades stops, a part of the pressure rollers and / or cutting blades are adjusted a first adjustment and / or a part of the pressure rollers and / or cutting blade a second adjustment be adjusted.
  • the advantage is that an adjustment of all pinch rollers and / or cutting blades can be done in one step, i. it is a simultaneous or immediately after each other feasible adjustment of all pinch rollers and / or cutting knife possible.
  • the position of the pinch roller and / or the position of the cutting blade depends on the web width and the configuration principle of the printing press. Either the formers are designed for the maximum web width and the narrower webs are each passed to the center of the fixed formers by means of turning devices, or the formers are for the minimum Web width and are pushed apart at a larger web width. This results in the in the Fig. 4 and Fig. 6 shown, different shape of the threaded spindle. The shape of the threaded spindle is thus dependent on the configuration principle of the printing system.
  • all pinch rollers and / or cutting knives of a pulling group can be adjusted in front of the former simultaneously or directly behind one another and monitored in their position with such a device, with only one adjusting motor and with only one position monitoring device.
  • this allows a format-independent design of this train group.
  • Fig. 1 is a folding structure 1 with double hopper, ie a lying in a plane adjacent the first former 2 and a second former 3, shown.
  • the pinch rollers 4 and 5 are cut by means not shown, lever mechanisms or directly to a printing material 9 and off. Opposite the pinch rollers 4 and the cutting blades 5 driven over the web width extending tension rollers 6, 8 and a knife roller 7 are arranged (see Fig. 2 ). Alternatively, instead of the draw rolls 6, 8, driven pull rolls positioned opposite the pinch rolls 4 and cutting knives 5 may also be used. Between these, the printing material web 9 is passed, wherein in each case on the front side 10 and on the back 11 of the printing substrate 9 eight pinch rollers 4 are adjustable.
  • Each of these eight pressure rollers 4, which are adjustable on the front 10 and the back 11, are mounted axially displaceably by means of a threaded bushing 12 designed, for example, like a lever, on a guide element 13.
  • the axial position of the pressure rollers 4 is fixed by the threaded bushing 12, in which a threaded spindle 14 can rotate. By rotating this threaded spindle 14, the axial position of the pressure rollers 4 can be adjusted.
  • a threaded spindle 14 is provided, so that at least two threaded spindles are present.
  • the cutting blade 5 can be arranged axially displaceably by means of the threaded bushes 12 and adjustable by rotating the threaded spindle 14 in its axial position on the upper guide member 13.
  • the cutting blade may also be arranged on a separate threaded spindle, so that the device for axially adjusting the pressure rollers and cutting blades with the above two threaded spindles for the pressure rollers comprises a total of three threaded spindles.
  • the bearing on the guide element 13 pinch rollers 4 and 5 cutting blade can be turned off, for example, to adjust their axial position of the printing substrate 9 and are employed again after the adjustment of its axial position to the printing substrate 9.
  • the threaded spindles 14 are preferably driven by a drive 23.
  • the drive 23 drives the threaded spindles 14 either via a gear 24, a Belt drive 25 or a chain drive 26 on.
  • a position monitoring device 27, for example, a rotary encoder is arranged on the drive 23, for example, one or more motors.
  • the position monitoring device 27 can, not shown in detail, also on the gear 24, the belt drive 25 or the chain drive 26 are arranged.
  • the position of pinch roller 4 and / or the position of the cutting blade 5 depends on the web width of the printing substrate 9 and on the configuration principle of the printing press.
  • the threaded spindle 14 for adjusting the pressure rollers 4 and 5 cutting knives according to the configuration principle I depending on the position of the pressure roller 4 and the position of the cutting blade 5 at certain areas A, B, C, D, E, F a different pitch and / or a different slope direction (see Fig. 4 ).
  • Fig. 3 schematically the configuration principle is shown.
  • the formers 2, 3 are designed for a maximum web width B max , wherein in a processing of narrower printing material 9 'this is cut before the, not shown, printing units by means of a cutting device 15 in two partial webs 16, 17 and then each the partial webs 16, 17 are guided to the center of the fixed former M F2 , M F3 by means of a, not shown, spreading device and turning devices 18.
