Definitions

  • the present invention relates to a reel changer for a rotary printing press according to the preamble of patent claim 1.
  • a double-armed reel changer in which the winding reel being developed is driven by a first belt lying against its surface, guided past the support arm, and in which the replacement reel before triggering the gluing process from an abutting surface second belt running substantially above the support arm is accelerated to the required unwinding speed.
  • the second belt is driven by a pulley, which is connected to the main shaft driving the first belt via an induction clutch and a further belt for the duration of the acceleration phase.
  • This reel changer has the disadvantage that it is only designed for winding reels of a certain diameter and a certain width and that the winding reel - except for a predetermined remaining length of the material web - must be completely unwound.
  • a winding roller that differs substantially in diameter from the predetermined size, it can be driven by the second belt, but its unwinding speed cannot be adapted to that of the remaining roller, since the induction coupling can only be regulated to a limited extent due to the task.
  • the installation of the complete printing press at a given installation location can be made difficult or even impossible by the swiveling range of the roller drive.
  • the object of the invention is therefore to design a reel changer requiring a small overall height in such a way that the acceleration to the unwinding speed and the driving and braking of each of the winding reels takes place until the end of one and the same belt, that the drive and brake belts are located within the winding reels extend enveloping circle and that the drive of the winding rollers can be controlled in a simple manner.
  • a roll carrier 1 which is essentially formed from two side elements 2 arranged parallel to one another and two support arm axes 3 and 4 connecting the side elements 2 at their ends, by one parallel to the support arm axes 3 and 4 extending pivot axis 5 pivotally mounted in both directions.
  • a pair of support arms 6 and 7 is freely movable.
  • the free ends of the support arms 6 and 7 are provided with roll holding and clamping mandrels 8 and 9 for receiving paper rolls 10 and 11, respectively.
  • the roll receiving and tensioning mandrels 8 and 9 are designed, for example, as radially expanding elements that self-tensioning via disc springs or compressed air.
  • the provision of freely movable support arms has the advantage that paper rolls of different widths can be processed one after the other.
  • the first paper roll 10 to be unwound is clamped on the roll support mandrels 8, while between the pair of support arms 7 on the roll support mandrels 9, the paper roll 11 is clamped, which is to be unwound following the roll 10 and the paper web of which is used for this (Not shown) adhesive and cutting device (auto paste) is glued to the end of the paper web of roll 10 at the appropriate time.
  • adhesive and cutting device auto paste
  • the paper roll 10 to be unwound is driven by a first pendulum roller drive 12, which essentially consists of a plurality of belts 13, which act as drive and brake belts and run parallel to one another, each via deflection elements such as pulleys 14, 15 and 16 arranged in a triangle as seen in the axial direction are guided and rest on the circumference of the paper roll 10, is formed.
  • the pendulum roller drive 12 oscillates about the axis of the pulleys 14 as the deflecting elements which are arranged closest to the support arm axis 4, its pivoting range being essentially between the circle that can be laid by the axes of the roller holding mandrels 8 and 9 and the enveloping circle surrounding the paper rollers 10 and 11 extends.
  • the paper roller 11 is driven by a second pendulum roller drive 21 formed from belts 17 and deflection elements such as pulleys 18, 19 and 20 and oscillating about the axis of the pulleys 18.
  • the structure of this spherical roller drive is the same as that of the first spherical roller drive 12, which is why only the first spherical roller drive 12 is described below.
  • the belts 13 and 17 running parallel to one another are considered as a single belt 13 and 17.
  • Both pendulum roller drives are driven by a belt drive motor 22, with which they can be connected by a respective transmission element 23 or 24.
  • the connection to the motor 22 is made by a switchable clutch 25 or 26 which can be arranged on the associated transmission element on the motor side (as shown in FIG. 1) or else on the belt drive side and which can also be designed so that it can be used alone or in Interacting with a direction reversal device drives the two pendulum roller drives independently of one another in both directions of rotation, for example to enable rewinding of the remainder of the roll of the separated roll.
  • a switchable clutch 25 or 26 which can be arranged on the associated transmission element on the motor side (as shown in FIG. 1) or else on the belt drive side and which can also be designed so that it can be used alone or in Interacting with a direction reversal device drives the two pendulum roller drives independently of one another in both directions of rotation, for example to enable rewinding of the remainder of the roll of the separated roll.
  • FIG. 2 shows the first pendulum roller drive 12 in its unwinding position to be found when the winding roller 10 is full.
  • the first arm 27 carries the pulley 14 and a first arm 29 which can be pivoted about the axis of the pulley 14.
  • the free end of the first arm 29 is connected to the free end by means of an adjusting device 31, which can be designed, for example, as a toothed rack or as a hydraulic cylinder the second arm 28 connected and also carries on an axis 32 a pivotable about this axis second arm 30.
  • the second arm 30 carries at its free end the pulley 15, the axis of the pulley 15 is mounted in an elongated hole 33 and with a second arm 30 attached compensating element 34 is connected.
  • the compensating element 34 which can be designed, for example, as a spiral spring set or as a hydraulic cylinder, ensures, in cooperation with the elongated hole bearing of the pulley 15, that the belt 13 has the correct belt tension at all times.
  • the second arm 30 is connected between an articulation point 35, which is determined at a distance from the axis 32, and an articulation point 36, which is determined on the first arm 29, with an adjusting element 37, which can be designed, for example, as a toothed rack or as a hydraulic cylinder.
  • a rod 39 is articulated to the first arm 29 at an articulation point 38, the pulley 16 being mounted on its free end 40.
  • An adjusting element 42 which can be designed, for example, as a toothed rack or as a hydraulic element, is articulated on the rod 39 at a suitable articulation point 41.
  • the adjusting element 42 is attached with its end facing away from the rod 39 at an articulation point 43 on the first arm 29.
  • FIG. 3 shows the first pendulum roller drive 12 in its unwinding position to be found when the winding roller 10 is completely unwound.
  • the pendulum roller drive 12 has a longer belt course compared to the prior art. This extended belt course enables the roller 10 to the end to be able to drive with the pendulum roller drive. This eliminates the auxiliary drive known from the prior art for the residual roll.
  • the adjusting elements 31, 37 and 42 are controlled in a manner known per se in such a way that the belt 13 rests non-positively on the surface of the paper roll 10.
  • the power transmission to the belt takes place through the pulley 14, which in turn is connected to the belt drive motor 22 via the transmission element 24, such as a drive shaft, and the clutch 26.
  • a new paper roll 11 can be stretched onto the support arms 7 and prepared for gluing. If there is a criterion for a roll change, the roll carrier 1 is pivoted in order to interchange the positions of the rolls 10 and 11. Then the paper roll 11 is accelerated to the required unwinding speed and glued to the running paper web by means of an adhesive and cutting device (not shown) and unwound instead of the paper roll 10. By pivoting the roll carrier 1, the support arms 6 are brought into a position in which a new paper roll can be fed or clamped manually or automatically and optionally also from a roll transport system.
  • the roll changer according to the invention shown schematically in FIG. 4 as a second exemplary embodiment has one Roller support 101, which is essentially formed from two side elements 102 arranged parallel to one another and two support arm axes 103 and 104 connecting the side elements 102 at their ends, on which is pivotally mounted in both directions about a pivot axis 105 running parallel to the support arm axes 103 and 104 is.
