Definitions

  • the invention relates to a clamping device for an axially displaceable actuator for gripper reversal on a gripper cylinder of a turning device in a sheet-fed rotary printing press, which has the training features according to the preamble of claim 1.
  • Such a clamping device is known from DE-PS 38 14 831.
  • a preloaded spring which in the operating state permanently loads the clamping device with its reaction force, is a component of a device for adjusting the rotational position of the gripper cylinder of a turning device with a clamp between a fixed gear and one adjusting gear arranged coaxially.
  • the spring effecting this clamping is supported at one end against a radial flange on a push rod which is movably guided in the gripper cylinder axially parallel to the longitudinal axis of the gripper cylinder and acts with the inner end on an abutment on a double lever, which is pivotable in the gripper cylinder about a transverse axis and on a second arm has a support for clamping pieces, which are guided in the adjusting member directly or via further intermediate members movable radially to the longitudinal axis of the gripper cylinder , so that the reaction force of the spring of the gearwheel clamp acts via the push rod and the pressure lever on the clamping pieces and causes the clamping of the adjusting member on the gripper cylinder corresponding to the clamping between the adjusting gear and the fixed gear.
  • the spring tension can be reduced by an adjusting element integrated in an electrical fuse, so that the clamping of the gearwheels and thus at the same time the adjusting member on the gripper cylinder is released and the changeover process is made possible, for example by turning an eccentric mechanism by means of a socket wrench or the like either directly on the gripper cylinder or via an actuator shaft on the drive side.
  • a socket wrench or the like either directly on the gripper cylinder or via an actuator shaft on the drive side.
  • the clamping of the adjusting member extending over the length of the gripper cylinder is only provided at one point and is shown in the document near the cylinder end on the drive side. No clamping is provided on the operating side, but the adjusting member is only guided between adjustable guide strips on the drive side and on the operating side. In order to enable an axial movement of the adjusting element, it must be between this and Guide rails a little game exist. Within this game, the adjustment member can move on the operating side while the machine is running, especially at high machine running speeds. These micro movements lead to pass rust, that is, to abrasion with fine dust formation, so that the free movement of the adjusting member on the gripper cylinder is no longer given and can no longer be adjusted in the conventional manner.
  • the invention has for its object to prevent such micro-movements and thus the formation of pass rust.
  • the invention solves this problem by the training features according to the characterizing part of patent claim 1.
  • the adjusting member which extends axially on the gripper cylinder is held not only on the drive side but also on the operating side, and thus at at least two points, by clamping on the gripper cylinder, in order in this way to prevent micro-movements which favor the formation of pass rust.
  • the bearing pin of the pressure lever is designed as a rolling pin and is axially movable in the gripper cylinder to its longitudinal axis and is rotatably coupled to an axially displaceable pressure member in the gripper cylinder, which acts on a further pressure lever, which is movably mounted on the operating side in the gripper cylinder about a fixed transverse axis, has an abutment for the pressure member and offset at an angle to a support for clamping pieces, which are provided according to claim 2 that the bearing pin of the pressure lever is designed as a rolling pin and is axially movable in the gripper cylinder to its longitudinal axis and is rotatably coupled to an axially displaceable pressure member in the gripper cylinder, which acts on a further pressure lever, which is movably mounted on the operating side in the gripper cylinder about a fixed transverse axis, has an abutment for the pressure member and offset at an angle to a support for clamping pieces, which are
  • the reaction force of the spring effecting the clamping between the fixed gear and the adjusting gear is simultaneously transmitted to a plurality of clamping pieces which are arranged at a distance from one another in the direction of the longitudinal axis of the gripper cylinder, so that the clamping of the axially movably arranged adjusting member with the gripper cylinder at several points simultaneously with the clamping of the drive gears.
  • Claims 3 to 5 contain further advantageous features for the constructive design of the inventive concept.
  • the gripper cylinder 2 mounted in the machine frame 1 is firmly connected on the drive side outside the machine frame by means of screws 3 to a fixed gear 4, which has a pin attachment on which a crown-like adjusting gear 5 is arranged so as to be adjustable in the angle of rotation.
  • a support plate 7 is fastened to the end face of the pin attachment of the fixed gear 4 by means of screws 6, against which a plurality of radially directed and evenly distributed pressure levers 8 are supported, one end of which against an annular surface 9 on the adjusting gear 5 is effective and the other end of which rests against a disk 10 acting as a spring-loaded pressure member, the pressure levers 8 being supported on their rear side against the support plate 7 by cams 11 arranged in the vicinity of the outer ends of the pressure levers 8.
  • the disc 10 is axially movable on a push rod 12, which in turn is axially movable in the gripper cylinder 2 parallel to the axis thereof and has a radial flange 13 against which a spring 14 is supported, which on the other hand is effective against the disc 10.
  • the Example shows a spring 14 made of alternately arranged disc springs, which are arranged with a bias and load the pressure lever 8 at the inner ends and thus at the end of the long lever arms.
  • the pin 15 shown in FIG. 1 engages with its ends in bores on the one hand on the radial flange 13 and on the other hand in the gripper cylinder 2, so that the push rod 12 is secured against rotation.
  • a pressure ring 16 penetrated by the push rod 12 with an integrated roller bearing 17 is effective against the disk 10, against the other end of which a threaded sleeve 18, which can be screwed onto a thread of the push rod 12, is movable, which is actuated by an actuating member Example by a hexagon head 19, can be screwed.
  • a game 20 between the threaded sleeve 18 and the pressure ring 16 allows the release of the clamping coupling between the fixed gear 4 and the adjusting gear 5 only when an electrical fuse has been actuated, so that only after movement of the threaded sleeve 18 forces on the pressure ring 16 to reduce the reaction force exerted by the bias of the spring 14 on the pressure lever 8 can take effect.
  • the threaded sleeve actuates a switch 21 via a double lever 23 which is fixed to the machine at 22 and which engages with one end in an annular groove on the circumference of the threaded sleeve 18 and the other end of which acts on the actuating member of the switch 21.
  • This end of the lever extends between a stop 25 and a spring 26.
  • the spring 26 returns the double lever 23 to the stop position in which the switch 21 releases the circuit of the machine when the gears 4 and 5 are clamped.
  • the Switch 21 is operated to interrupt the circuit for driving the machine before the pressure ring 16 is axially displaced against the disk 10 to reduce the reaction force effect of the spring 14 on the ends of the pressure lever 8.
  • the pressure ring 16 is arranged on a step of the pressure rod 12 which has a smaller diameter than the part passing through the spring 14, so that a step-shaped stop is formed for the movement of the pressure ring 16.
  • the other end of the push rod acts against an angular pressure lever 27 which is movable in the gripper cylinder in the area of the axially movable adjusting member 28 about a bearing pin 29 arranged transversely to the longitudinal axis of the gripper cylinder.
  • this pressure lever 27 engages under a clamping bracket 30, the ends of which are each connected by a tension bolt 31 and 32 to clamping pieces 54 and 55 arranged in recesses of the adjusting member 28, which act on the ends of the clamping bracket 30 via washers 33 and 34.
  • the tension bolts 31 and 32 engage behind the clamping bracket 30 with a collar head and are guided through bores in the clamping bracket 30 and the adjusting member 28.
  • the push rod 12 transmits the reaction force of the spring 14 via the pressure lever 27 to the clamping bracket 30, so that the reaction force acts via the tension bolts 31 and 32 as a clamping force on the clamping pieces 54 and 55 and presses the adjusting member 28 against seating surfaces which are on the circumference of the gripper cylinder 2 are formed.
  • the contact surfaces of the pressure lever 27 and the clamping bracket 30 uniform clamping forces are achieved on both clamping pieces 54 and 55, the contact surfaces possibly using pressure disks can be formed from a wear-resistant material.
  • the clamping pieces 54 and 55 can be screwed onto the free ends of the tension bolts 31 and 32, so that an adjustment of the clamping forces and a play 35 between the push rod 12 and the transmission members is possible and the adjusting member 28 can be adjusted axially when the spring 14 is used Reduction of the reaction forces from the bias of the spring, which acts on the pressure lever 8, is compressed, the push rod 12 moving to the left in the drawing until the pressure ring 16 touches the stop shoulder of the push rod 12.
  • the axially movable adjustment member 28 for gripper changeover is designed as a slide which extends across the width of the machine and is guided in a recess in the gripper cylinder 2 on guide strips 38 and 39 which can be adjusted by screws 36 and 37, both on the drive side and on the operating side the adjusting member 28 is also clamped at at least two points, advantageously on the drive side and on the operating side.
  • the bearing pin 29 of the angular pressure lever 27 is designed as a rolling pin and is movably mounted in the gripper cylinder 2 axially to its longitudinal axis.
  • the rolling pin 29 is also rotatably coupled to an axially displaceable in the gripper cylinder 2 pressure member 57, which acts on a further pressure lever 58 which is movably mounted on the operating side in the gripper cylinder 2 about a fixed transverse axis on a hinge pin 59.
  • This pressure lever 58 also has an abutment for the facing end of the pressure member 57 and offset at an angle to a support for clamping pieces 60, 61, which on the operating side radially to the longitudinal axis of the gripper cylinder 2 is guided in the adjusting member 28 in a radially movable manner and, in accordance with the design on the drive side, is connected by means of tension bolts 62 and 63 to a clamping bracket 64, which is gripped by the support of the pressure lever 58, which is arranged at an angle.
  • the pressure member 57 is fork-shaped at the drive end so that it partially engages around the pressure lever 27 with this fork design. Bearing eyes for the storage of the ends of the roller bolt 29 are arranged in the free leg ends of the fork.
  • reaction forces of the spring 14 causing the axial adjustment member 28 to be clamped are transmitted from the push rod on the one hand to the pressure lever 27 and from this to the clamping pieces 54 and 55 provided on the drive side and at the same time via the rolling pin 29 and the fork-shaped pressure member 57 to the pressure lever 58 and thus also transferred to the clamping pieces 60 and 61 on the operating side, the rolling pin rolling off minimally based on the adjustment paths on the rolling plates 65 and 66.
  • the eccentric mechanism consisting of the eccentric pin 40 and an eccentric pin 41 engaging in a bearing 56 of the adjusting member 28 serves to axially adjust the adjusting member 28 for the gripper reversal.
  • the eccentric pin 40 is adjusted in the example via an angular gear made of bevel gears 42 and 43 and a selector shaft 44 which can be rotated in the gripper cylinder 2 is stored.
  • the outer end of the control shaft is guided outwards through the support plate 7 and has an actuating element, for example a hexagon head 45, for a socket wrench 46.
  • the actuation of this hexagon head 45 can be included in the electrical protection in a manner known per se.
  • a variant is shown in which one or more clamping pieces 60, 61 movable radially to the longitudinal axis of the gripper cylinder 2 are connected on the operating side via tension bolts 62, 63 to a clamping bracket 69, which is angled to the direction of movement of the pressure member 57 has wedge surface 67 which interacts with a wedge surface 68 which is formed directly on the pressure member 57.
