Definitions

  • the invention relates to a device for automatically controlling the working distance of the jaws of a jaw cylinder.
  • the invention has for its object to provide a device that enables a folding jaw working distance can be set independently depending on a paper web thickness.
  • the advantages of the invention are, in particular, that the folding jaw working distances are set directly as a function of the actual paper web thickness, so that setting errors which can occur during manual adjustment are excluded.
  • the operation that includes the jaw adjustment can be omitted.
  • the folder can also be included, since the setting of the jaws can be fully automated.
  • the control of the jaws by means of exclusively rotatable actuators favors the functional conditions.
  • a folding jaw cylinder 1 is supported by means of roller bearings 2, 3 in side frames 4, 6 of a folding device 7.
  • the jaw cylinder 1 consists of a cylinder shaft 8, a carrier device consisting of two carrier disks 9, 11 for a movable row of folding jaws 12 and a carrier device consisting of two carrier disks 13, 14 for a stationary row of folding jaws 16.
  • a carrier device consisting of two carrier disks 9, 11 for a movable row of folding jaws 12
  • a carrier device consisting of two carrier disks 13, 14 for a stationary row of folding jaws 16.
  • several rows of jaws 12, 16 can also be provided . For the sake of simplicity, however, only one pair of folding jaw rows 12, 16 is described.
  • the carrier disks 9, 11, 13, 14 can be pivoted about the cylinder shaft 8 by means of slide bearings and can be connected in a rotationally fixed manner to the cylinder shaft 8 by means of couplings (not shown).
  • On a left end of the Cylinder shaft 8 has a drive gear 17 for the jaw cylinder 1 firmly wedged.
  • An output gear 18 is also wedged on a right end of the cylinder shaft 8.
  • the cylinder shaft 8 has on its right side an axial bore 19 which extends over approximately one third of the cylinder wavelength. At the end of the axial bore 19, a radial bore 21 is provided.
  • the bores 19, 21 serve to receive actuating shafts 22, 23 with roller bearings, which are at a deflection point 24 by means of a bevel gear set 26, consisting of two intermeshing bevel gears, with each other in torque transmission.
  • a pipe section 27 is welded to the cylinder shaft 8.
  • the pipe section 27 serves as a fixed bearing for an adjusting spindle 28 which has a right-hand and a left-hand thread at its ends.
  • the actuating shaft 28 is also in torque transmission with the radially arranged actuating shaft 23 by means of a second bevel gear set 29 consisting of two intermeshing bevel gears.
  • the right-hand end of the axial actuating shaft 22 protrudes from the bore 19 and at this end carries a drive gear 31, which has the same diameter as the driven gear 18, in a rotationally fixed manner.
  • the adjusting spindle 28 is in screw contact with one each with its left and right-hand thread ends Adjustment bracket 32.33.
  • the adjustment carriers 32, 33 are each in the carrier disks 9, 11; 13,14 stored in radially arranged slots 34 to 37. Due to the arrangement of the adjustment carriers 32, 33 in elongated holes 34 to 37, compensatory movements can be carried out which are necessary to convert the translational movement generated by the adjusting shaft 28 into a rotational movement of the carrier disks 9, 11; 13.14 implement.
  • a control cam 38 is attached to the side frame 4 in a known manner.
  • a control roller 39 runs on the circumference and controls the opening stroke of the movable folding jaws 12. An actuating movement for a working distance a between the jaws 12, 16 is initiated via the drive gear 31.
  • the drive gear 31 is driven by an output part 41 of an adjustment gear 42 by means of a first toothed belt 43.
  • the adjustment gear 42 has, in addition to the driven part 41, a drive part 44, which is in drive connection by means of a second toothed belt 46 with the driven gear 18 of the jaw cylinder shaft 8 and a control part 47, which is connected by means of a third toothed belt 48 with a drive gear 49 of a servomotor 51 and a drive gear 52 of an actual value sensor 53 is in drive connection (FIG. 5).
  • the servomotor 51 receives its positioning commands in the form of electrical signals that are generated by a three-point controller 50.
  • the three-point controller 50 is connected to the actual value sensor 53 and a changeover switch 54 by means of an electrical line.
  • the changeover switch 54 forwards a setpoint to the three-point controller 50.
  • the nominal value (paper strand thickness d) can be entered either by means of an input device of a computer 56 or by means of a measurement sensor 57.
  • the transducer 57 measures the thickness d of a strand of paper 58 which is fed to the folder 7.
  • the transducer 57 is arranged behind a transfer roller 61 and in front of a pair of draw rollers 62, as seen in the direction of the paper strand.
  • the folder 7 contains, for example, a cutting cylinder 67, a collecting cylinder 68, the folder cylinder 7, a bucket wheel boom 69 and a conveyor belt 70.
  • the transducer 57 consists of a rotatably mounted, preferably chrome-plated roller 71 and a chrome-plated measuring roller 72.
  • the roller 71 is mounted in the side frames 4, 6.
  • the measuring roller 72 is rotatable at the end of a lever arm 73 stored. This sits in a rotationally fixed manner on a shaft 74 which is pivotably mounted in the side frames 4, 6.
  • the paper strand 58 is passed between the roller 71 and the measuring roller 72, so that the measuring roller 72 is deflected more or less depending on the paper strand thickness d, which results in a pivoting movement of the shaft 74.
  • An adjusting lever 76 is arranged in a rotationally fixed manner on an end of the shaft 74 which projects through the side frame 4.
  • a displacement transducer (e.g. moving coil device) 77 is pivotally connected to the actuating lever 76 approximately in the center and is pivotally arranged at one end on a frame plate 78 of the measurement transducer 57.
  • a return spring 79 fastened to the frame plate 78 is provided at one end of the adjusting lever 76.
  • Two adjustable stops 81, 82 fastened to the frame plate 78 limit the pivoting angle of the actuating lever 76 and thus the deflection of the measuring roller 72.
  • the maximum deflection can e.g. as a result of a web break with paper web stuffing.
  • the stops 81, 82 protect the plunger winding device 77 from being destroyed.
  • the frame plate 78 is pivotally mounted about the shaft 74 between the side frame 4 and the actuating lever 76.
  • the frame plate 78 is pivoted by means of an air cylinder 84 which is fastened to the side frame 4 and which engages at one end of the frame plate 78.
  • An adjustable stop 83 attached to the side frame 4 limits the position of the frame plate 78 for a zero position from the measuring roller 72 to the roller 71. In the zero position, the peripheral surfaces of the roller 71 and the measuring roller 72 are in contact, i.e. the paper strand thickness d is zero.
  • the air cylinder 84 is articulated on an outside of the side frame 4 and connected to a pressure medium generation source 87 by means of a switching valve 86.
  • displacement transducers can also be used instead of the plunger winding device 77.
  • non-contact and touch-sensitive displacement measuring devices are equally suitable.
  • this setpoint can also be determined by measuring the paper strand thickness d and, after a setpoint / actual value comparison, can be forwarded to the servomotor 51 as a command.
  • the measuring roller 72 is placed against the stationary roller 71 by means of the air cylinder 84.
  • the air cylinder 84 pivots the frame plate 78 against the stop 83.
  • the measuring roller 72 is pivoted accordingly until it rests on the paper strand 58.
  • the remaining pivoting path until the frame plate 78 bears against the stop 83 by a relative pivoting movement of the actuating lever 76 is added.
  • a plunger anchor of the plunger device 77 is pushed correspondingly far into the plunger device 77.
  • a voltage signal injected by the sliding movement is fed to the three-point controller 50 as a measurement-dependent setpoint.
  • a manipulated value is formed and this is fed to the servomotor 51 as a voltage signal.
  • the servomotor 51 rotates its drive gear 49 to the right or left depending on the amount and direction of the manipulated value.
  • the belt connection 48 of the servomotor 51 with the control part 47 of the adjustment gear 42 a translation between the drive part 41 and the driven part 44 is generated during the rotation of the control part 47.
  • This translation leads to a relative movement between the input and output gear 31, 18 and thus to a rotation of the actuating shaft 23 about its axis of rotation 88.
  • the actuating shaft 22 rotates synchronously with the machine speed, while the actuating shaft 23 is stationary with respect to its own axis of rotation 88.
  • a threaded end 92; 93 of the actuating shaft 28 engages in a threaded bore 94; 96 of a bolt 97; 98.
  • the bolt 97, 98 is fitted into the adjustment support 32, 33.
  • a bore 99, 101 running in the axial direction of the adjusting shaft 28 in the adjustment support 32; 33 coaxially envelops the threaded ends 92, 93 so that the threaded ends 92, 93 can engage in the threaded bores 94, 96 of the bolts 97, 98.
  • one axial bearing 102; 103 protects the bevel gears of the bevel gear set 29 against axial loads, caused by pivoting movements of the carrier disks 9, 11, 13, 14.
  • a jaw shaft 104 is pivotally mounted in the carrier disks 9, 11.
  • the jaws 12 are fixed at intervals on the jaw shaft 104 so that they are pivoted synchronously with the jaw shaft 104.
  • the jaw flap shaft 104 projects through the carrier disk 9 and carries a bracket 106 for the control roller 39, which is firmly wedged on this end.
  • the carrier disks 13, 14 have a receptacle 107 for a folding jaw strip 108 on their circumference.
  • the jaws 16 are bolted to the jaw strip 108 at intervals. The jaws 16 only move together with the carrier disks 13, 14.
