Definitions

  • the present invention relates to a device for adjusting the jaws on a jaw cylinder according to the preamble of claims 1 and 8.
  • a folding cylinder which has at least one fixed folding strip arranged on the circumference and at least one cooperating controlled folding flap, the working distance of which can be adjusted by opposing adjustment of the folding strip and folding flap.
  • the controlled folding flap is pivotally mounted eccentrically in a carrier holding the fixed folding strip, which can be rotated by means of an adjusting device, and is connected in a torsionally elastic manner to the carrier of the folding cylinder by means of a torsion spring.
  • the carrier is connected in an articulated manner to a lever which engages on a tab of the carrier and which is adjustable in the radial direction by means of a slider which is displaceable in a coaxial recess of the cylinder axis and has an inclined plane.
  • the slider is an axial bearing with a fixed in the direction of rotation and axially by means of an actuator, such as a handwheel, movable spindle connected.
  • the object of the present invention is therefore to design a device for adjusting the jaws on a jaw cylinder so that assembly and adjustment of the device are simplified considerably and that the wear is significantly reduced and is independent of the number of flap pairs to be controlled.
  • Fig. 1 shows a highly schematic representation of a device for adjusting the jaws on a jaw cylinder in a first embodiment of the invention.
  • the jaw cylinder 1 has a jaw cylinder axis 2 and two essentially cylindrical jaw bodies 6 and 7, which are arranged coaxially one inside the other and pivotable in an angular range around the jaw cylinder axis 2 and provided with jaw pairs 3. While a plurality of controllable folding jaws 4 are attached to the jaw body 6, a plurality of fixed jaws 5 are attached to the jaw body 7.
  • a controllable folding jaw 4 and a fixed folding jaw 5 each form a pair of folding jaws 3.
  • the control of the folding jaws 4 during the folding process on the then rotating jaw cylinder 1 is carried out in a manner known per se and not essential for the present invention by means of a running on a cam disc Control role (both not shown).
  • FIG. 3 The arrangement of the jaw pairs 3 in the jaw cylinder 1 is shown in FIG. 3 by way of example for a single jaw pair 3.
  • the device required for controlling the folding jaw 4 is symbolically represented by a lever 40.
  • a first gear 8 is fixedly mounted on the jaw cylinder axis 2.
  • the Gear 8 is connected via a gear block 13, which has at least two toothed rings 31 and 32 provided with external teeth, to a second gear 9 arranged coaxially on the cylinder axis 2 and rotatable with respect to the jaw cylinder axis 2.
  • the gear wheel 9 and the jaw body 6 are firmly connected to one another by a first flange sleeve 15 which is mounted coaxially on the jaw cylinder axis 2 and rotatable relative thereto. With this arrangement, the controllable jaws 4 are driven synchronously with the gear 8.
  • the flange bushing 15 is formed like a collar at its end facing away from the gear 8 and is fixedly connected to a third gear 10 which is arranged coaxially with the jaw cylinder axis 2 and which engages with a reversing gear 14.
  • the direction of rotation reversal gear 14 has a frame 14 ′ which is fixedly connected to the jaw cylinder axis 2 and on which a plurality of gearwheels, which is essential for the present invention only with regard to its overall effect, is rotatably mounted: when the jaws are adjusted, the direction of rotation reversal gear 14 transmits the relative rotational movement of the jaw body 6 of the jaw cylinder axis 2 in a ratio of 1: 1 and with simultaneous reversal of the direction of rotation on the jaw body 7.
  • the folding jaw body 7 has a flange 71 and 72, respectively, on its two end faces.
  • the flange 71 is partially or completely provided with an external toothing 11, which is in engagement with the reversing gear 14, while the flange 72 is provided with an external toothing 18.
  • an additional reversing gear 114 which is the same as the direction of rotation reversal 14 and is arranged in mirror image relative to it, can be provided on the flange 72 and has a frame 114 'fixedly connected to the jaw cylinder axis 2.
  • the direction of rotation reversal gear 114 engages with the external toothing 18 and a gearwheel 10 ′ attached to the jaw body 6 and thus connects the two jaw bodies 6 and 7.
  • the gear block 13 has an essentially hollow cylindrical support body 24, which is provided with an internal thread 23 for receiving an actuating element 25 and is axially displaceably arranged on a pin 33 and secured against rotation.
  • the at least two ring gears 31 and 32 are arranged coaxially and rotatably on the carrier body 24.
  • the carrier body 24 is rotatably connected via the internal thread 23 to a threaded spindle 25 serving as an actuating element.
  • the threaded spindle 25 is driven by a controllable motor drive device 30, which enables remote adjustment of the folding jaws, with feedback via potentiometers.
  • Driving the threaded spindle 25 causes an axial displacement of the gear block 13, which, due to the combination of the toothing of the ring gears 31 and 32 and the gears 8 and 9, results in the gear 9 rotating relative to the gear 8.
  • the reversal of the direction caused by the reversing gear 14 and possibly also by the additional reversing gear 114 results in an adjustment of the jaw body 7 in the opposite direction.
  • a handwheel 29 can also be provided for driving the threaded spindle 25, as described in more detail in connection with the second exemplary embodiment and shown in FIG. 2.
  • Fig. 2 shows a highly schematic representation of a device for adjusting the jaws on a jaw cylinder in a second embodiment according to the invention.
  • the folding jaw cylinder 1 shown in FIG. 2 has a folding jaw cylinder axis 2 and two thereon lying coaxially one inside the other and in an angular range around that
  • the jaw cylinder axis 2 has pivot jaw bodies 6 and 7 which are pivotally arranged and provided with jaw pairs 3. While a plurality of controllable folding jaws 4 are attached to the jaw body 6, a plurality of fixed jaws 5 are attached to the jaw body 7.
  • a controllable folding jaw 4 and a fixed folding jaw 5 each form a pair of folding jaws 3.
  • the arrangement of the jaws 3 in the jaw cylinder 1 is shown in FIG. 3 as an example for a single jaw pair 3.
  • the jaw cylinder axis 2 is firmly connected to a fourth gear 108 coaxially mounted on it. Furthermore, a fifth gear 109 and a sixth gear 110 are arranged coaxially and rotatably on the jaw cylinder axis 2.
  • the fifth gear 109 is fixedly connected to the jaw body 7 via a second flange sleeve 16, which comprises the cylinder axis 2 and is rotatably mounted thereon.
  • the sixth gear wheel 110 is fixedly connected to the jaw body 6 via a third flange sleeve 17, which surrounds the second flange sleeve 16 and can be rotated relative to the latter. While the fourth gear 108 is currently toothed, the fifth gear 109 and the sixth gear 110 are helically toothed in opposite directions.
  • the gears 108, 109 and 110 are in engagement with a gear 112.
  • the transmission 112 has a pinion shaft 119, a first pinion 120, a second pinion 121 and a third pinion 122. While the first pinion 120 is straight-toothed, the second pinion 121 and the third pinion 122 are oppositely helical, in such a way that the respective pitch direction of the second pinion 121 and the third pinion 122 corresponds to the respective pitch direction of the gear 109 and the gear 110, with which the two pinions 121 and 122 are engaged, is directed in the opposite direction.
  • the gears 108, 109 and 110 interact with the pinions 120, 121 and 122 in such a way that a rotation of the gear 109 relative to the gear 108 is converted into an opposite rotation of the gear 110.
  • the gear 112 is rotatably connected by means of a holder 126 to a threaded spindle 125 serving as an actuating element.
  • the Threaded spindle 125 is rotatably mounted in a carrier plate 127 with an adjacent threaded part 128 and in a counter bearing 133 and is firmly connected to a handwheel 29 at the end facing away from the holder 126.
  • the handwheel 29 is actuated, the threaded spindle 125 is rotated together with the holder 126, as a result of which the gear 112 is adjusted in the axial direction.
  • the axial adjustment of the gear 112 results in a relative rotation of the gear 109 relative to the gear 108 in one direction and a relative rotation of the gear 110 relative to the gear 108 due to the combination of the different toothings of the pinions 120 to 122 and the gears 108 to 110 opposite direction.
  • These adjustment movements together result in a simultaneous forceps-like adjustment movement each of a controllable folding jaw 4 and an associated fixed folding jaw 5, so that it is not necessary to readjust the folding blades of a folding blade cylinder 200 interacting with the folding jaw cylinder 1.
  • a controllable motor drive device 30 can also be provided for driving the threaded spindle 125, as described in more detail in connection with the first exemplary embodiment and shown in FIG. 1.
  • Fig. 4 shows a highly schematic representation of a device for adjusting the jaws on a jaw cylinder in a third embodiment of the invention.
  • the jaw cylinder 1 has a jaw cylinder axis 2 and two coaxially one inside the other and pivotably arranged in an angular range around the jaw cylinder axis 2, provided with jaw pairs 3 and essentially cylindrical jaw bodies 6 and 7. While a plurality of controllable folding jaws 4 are attached to the jaw body 6, a plurality of fixed jaws 5 are attached to the jaw body 7.
  • a controllable folding jaw 4 and a fixed folding jaw 5 each form a pair of folding jaws 3, as has already been done with reference to FIG. 3 for the first two Exemplary embodiments have been explained.
  • the control of the jaws 4 during the folding process on the then rotating jaw cylinder 1 takes place in a manner known per se and not essential for the present invention by means of a control roller running on a cam (both not shown).
  • a seventh gear 308 is fixedly mounted on the jaw cylinder axis 2.
  • the gearwheel 308 is connected via a gearwheel block 313, which has at least two toothed rings 331 and 332 provided with an external toothing, to an eighth gearwheel 309 which is arranged coaxially on the jaw cylinder axis 2 and rotatable relative thereto.
  • the gearwheel 309 and the jaw body 6 are, via a gear train, which is composed of a fourth flange sleeve 315, which is coaxially mounted on the jaw cylinder axis 2 and rotatable relative to the latter, and which is configured like a collar at its end remote from the gear wheel 308, a ninth gearwheel arranged coaxially with the jaw cylinder axis 2 310, which is fixedly connected to the collar-shaped end of the flange sleeve 315, a first tooth element 303, which engages with the gearwheel 310, and a first spindle 301, which is rotatably mounted in the jaw body 6, axially parallel to the jaw cylinder axis 2, and on which the tooth element 303 is firmly attached, assembled, connected.
  • a gear train which is composed of a fourth flange sleeve 315, which is coaxially mounted on the jaw cylinder axis 2 and rotatable relative to the latter, and which is configured like a collar at its
  • the reversing gear 314 also has a frame 320 which is fixedly connected to the jaw cylinder axis 2 on which an essentially circular segment-shaped third tooth element 311 with an internal rolling circle and an essentially circular segment-shaped fourth tooth element 312 with an external rolling circle are fixedly attached. While the tooth element 311 is connected to the gear wheel 302 in a non-positive or positive manner, the tooth element 312 is connected to the gear wheel 305 in a non-positive or positive manner. Furthermore, the frame 320 has an elongated hole 321 through which the spindle 301 is passed without contact.
  • the direction of rotation reversal gear 314 transmits the relative rotational movement of the gear 309 relative to the gear 308 by rolling the gear 302 on the tooth element 311 when the jaws are adjusted, whereby the spindle 301 is moved in the circumferential direction of the jaw body 6, and by rolling the gear 305 on the tooth element 312 , whereby the spindle 304 is moved in the circumferential direction of the jaw body 7, simultaneously and in the same overall transmission ratio, but with the opposite direction of rotation, onto the jaw bodies 6 and 7. This results in a simultaneous adjustment of all jaw pairs 3 of the jaw cylinder 1 that is symmetrical to the respective jaw knife.
  • FIG. 5 shows a highly simplified illustration of an axial view of the arrangement of the essential elements of the reversing gear 314 described in the third exemplary embodiment.
  • a handwheel 29 as described in more detail in connection with the second exemplary embodiment and shown in FIG. 2, a controllable motor drive device 30, as described in more detail in connection with the first exemplary embodiment, can be used to drive the threaded spindle 325 described and shown in Fig. 1, or any other appropriate, not necessarily permanently connected to the threaded spindle 325 drive device.
