Definitions

  • the invention relates to a device for feeding the paper webs of a plurality of supply rolls to parallel paper insertion slots of a printing machine, in particular a ticket printing machine, in which in each case one of the introduced paper webs is conveyed to a printing station, printed, the printed paper web piece is cut off and output.
  • the paper webs are fed to the slots via deflection rollers, the guide directions being in a plane perpendicular to the slots, for which purpose the supply rollers were arranged one above the other or one behind the other and their axes and the axes of all deflection rollers were arranged parallel to the slots.
  • the arrangement of the supply rolls took up a housing space corresponding to the width of one or the widest paper web or supply roll, on the front narrow side of which the printed and cut-off pieces of paper web (in particular, for example, tickets) were issued. Only a few (e.g. three) supply rolls can be arranged one above the other; Because the desired large stock of each paper web requires large diameter supply rolls, of which the uppermost one should also be accessible for replacement from the ground. Arranging the supply rolls one behind the other is practically out of the question because of the large depth dimension of the device, because such devices (in particular, for example, ticket machines) are usually set up on a wall on which they should not protrude far.
  • the object is achieved to provide a device of the type mentioned, which makes it possible to guide paper webs (also) from supply rolls arranged laterally offset to the slots in the slot direction to the slots, so that supply rolls can also be arranged side by side in the axial direction.
  • Each guide channel is equipped with a gripper that holds the paper web in the rest position.
  • the gripper for the paper web to be printed in each case advances it until it has run into the nip of the rotating pair of rollers, then releases it and initially remains in its advanced position.
  • the pair of rollers continues to feed the paper web first into its printing position, after printing into its cut-off position and backwards after cutting.
  • the gripper grabs again and goes in its rest position, taking the paper web with it, so that its end formed by the cutting comes into the position in which its previous free end was before the gripper advance. In this way it is possible to print on different paper webs in any order and also immediately one after the other on one and the same paper web.
  • Each of the supply rolls 11-16 is assigned one of the deflection rolls 31-36, from which the paper web continues in a direction which is independent of the diameter of the paper roll, which becomes smaller as the supply decreases.
  • a dancer 40 which is described in more detail below and which has a deflection member 41-46 for each of these paper webs 1-6, from which the paper web runs to one of the slots 21-26 provided for it.
  • the supply rolls 11, 16, 17 are superimposed and, like the deflection rolls 31, 36, 37 and the deflection members 41, 46, 47, with their axes or axes of curvature arranged parallel to the slots 21-27 so that all path sections of the paper webs 1 , 6 and 7 are perpendicular to the slots 21-27.
  • the paper web 1 runs along an arc around the deflection roller 31 and also (ie again along an arc) on a sliding surface of the deflection member 41 of the dancer 40
  • the paper web 6 runs along an arc around two deflection rollers 36, 56 and also on a sliding surface of the Deflection member 46 of the dancer 40
  • the paper web 7 runs along a circular arc on a deflection member 57 formed by a guide plate. All straight path sections and all circular path sections and accordingly all deflection angles of the paper webs 1, 6 and 7 lie in one to the insertion slots 21- 27 vertical plane.
  • the supply rolls 12-15 are laterally offset from the insertion slots 21-27, so that the supply rolls 12, 13 on one (in FIG. 1 left) and the supply rolls 14, 15 on the other (in FIG. 1 right) side of the Are insertion slots 21-27 and the supply rollers 11, 16, 17 and the dancer 40 arranged above the insertion slots 1-7.
  • the axes of the supply rolls 12-15 are parallel to those of the supply rolls 11, 16, 17 and to the insertion slots 21-27. This is not necessary, but makes it possible to arrange the supply rolls 12, 14 close to the supply spool 11 and the supply spools 13, 15 close to the supply spool 16 in a space-saving manner.
  • the paper webs 2-5 On their paths leading obliquely from back to front and upwards or downwards, the paper webs 2-5 must be deflected by angles in planes which are at an angle to the axes of the supply rollers 11-17 and at an angle to the insertion slots 21-27.
  • the paper web 4 on a along a part of a helical winding deflection path around a deflection member formed by a rotatably mounted roller 54 with a flange 64 and then again on a along a part of a helical winding deflection path over a curved sliding surface of another deflection member 44 of the dancer 40 led.
  • each required angle of deflection in the required plane can be formed by two tangents of a helical turn (whereby the angle of deflection is to be understood as the angle which the initially oblique tangents form when one is displaced in parallel so that it intersects the other).
  • the path running along part of a helical winding is determined by the inclined position of the axis of the deflecting roller 54 with the flange 64 or the axis of curvature of the deflecting member 44 and by the feed and (at the deflecting member 44 practically vertical) trigger direction forced.
  • the paper tape 4 endeavors to run onto the deflection roller 54 at a position that continuously moves to the right in FIGS. 1 and 3, and to the rear in FIG.
  • the flange 64 of the deflecting member 54/64 is conical and attached or formed at the end of the roller 54 from which the path running along the helix turn leads away due to the pitch of the helix.
  • the edge of the paper web 4 first runs onto the flange 64. While the paper web 4 runs around the deflection member 54/64, it slides axially on the roller 54 in the direction pointing away from the flange 64, so that it is positioned laterally on the deflection member 54/64 maintains. If the deflection member 54/64 is formed with a fixed sliding surface instead of the roller 54 and the flange 64, then a lateral guide corresponding to the flange 64 is unnecessary. It has been shown that it is sufficient to guide the edges of the paper web 4 at the ends of the insertion slot 24.
  • the axis of the deflection member 54/64 is skewed to the axes of the deflection roller 34 and the supply spool 14, as well as to the slots 21-27.
  • the axis of curvature of the deflection member 44 lies in the feed plane of the slots 21-27 but is inclined to the slot direction.
  • the two deflection angles of the deflection members 54/64 and 44 lie in planes that lie obliquely in space.
  • the paper web 4 is guided on oblique paths to all three vertical coordinates (of the coordinate system given, for example, by the plane of the drawing in FIGS. 1-3) from the deflection roller 34 to the deflection member 44 on the dancer 40, in order finally to be straight to run into the insertion slot 24 of the printing press 2.
  • the paper webs 2, 3, 5 are guided from the deflection rollers 32, 33, 35 to the slots 22, 23, 25 in accordance with the guidance of the paper web 4 from the deflection roller 34 to the slot 24, so that this is for guiding the paper web 4 and to it Guide members 54/64 and 44 said analogously for the guidance of the paper webs 2, 3, 5 and their guide members 52/62, 42; 53/63, 43; 55/65, 45 applies.
  • the deflection members 41-46 are attached with their ends to two approximately vertical bars 81, 82.
  • the rung frame thus formed is guided in an approximately vertically movable manner by means of a straight handlebar guide with two parallelogram links 83, 84.
  • a torsion spring 85 engages the handlebar 84 and takes up the weight of the dancer 40 and the paper webs 1-6 acting on it and at the start of the advance temporarily gives in to one of the paper webs 1-6 lying on the deflection members 41-46 of the dancer until whose greater static friction has changed into the smaller sliding friction.
  • a sensor (not shown), which emits a signal to the control device of the printing machine when a certain supply is undershot, and a brake (not shown) are expediently provided, by means of which the tension of the paper web required for reliable guidance is ensured and prevented that the supply roll continues to rotate due to its inertia after a feed step of the paper web and the paper web relaxes.
  • the two supply rolls 11, 14 and 15, 16 and the two deflection rolls 31, 34 and 35, 36 are shown offset from one another in order to show the course of the paper web 1, 4 and 5, 6 separately.
  • a coaxial arrangement is also possible instead of the one shown.
  • deflection members with a fixed sliding surface can also be used, for example a first round rod can be provided instead of the deflection rollers 31, 32, 34 and a second round rod extending transversely to the device, instead of the deflection rollers 33, 35 and 36.
