Definitions

  • the invention relates to a device for remote-controlled actuation of clamping elements one Turning device in sheet-guiding cylinders and on Sidewalls of rotary printing presses, wherein via the clamping elements by applying a preload a clamping connection between power transmission elements adjustable relative to each other and between control segments using a movable, at least one-piece push rod is created and maintained.
  • JP 63-173644 A are actuating cylinders for releasing a clamping force between relative mutually adjustable toothed wheels of a turning cylinder known, in which the clamping force is applied by means of a compression spring.
  • the positioning cylinders are directly on the turning cylinder and thus rotatably arranged.
  • JP 63-173645 A shows actuating cylinders for moving a wedge bar.
  • the actuators are attached to the pin of a transfer cylinder and thus rotate together with the Transfer cylinder.
  • JP 63-173644 A and JP 63-173645 A have the disadvantage based on the fact that the actuating cylinders are rotatably arranged together with the cylinder need so-called rotary unions. Such rotary unions often have Sealing and leakage problems.
  • the object of the present invention is to develop the prior art further based on the requirements for a remotely controllable clamping device to create standardized, compact components.
  • Another embodiment of the solution according to the invention provides that the movable at least one part Push rods of non-rotatably mounted actuating cylinders that can be pressurized with fluid are included.
  • a particular advantage is the fact that on a separate the elaborate rotary joint to be provided can be dispensed with, which is the Manufacturing costs not insignificantly reduced.
  • delimiting Components do not rotate, so that there are no sealing and leakage problems occur
  • Solution is provided that in the pressurizable Actuating cylinder bearing elements can be used are. So these are both rotating on can also be used on non-rotating push rods, without changing the geometry of the actuators requirement. This makes them universally usable and producible in larger quantities, which is the manufacturing cost belittles.
  • An embodiment of this solution provides that the indirectly operable via a pressure medium Actuator cylinder receives an eccentric bolt, which has a lever with a second actuating cylinder in Connection is established.
  • the periphery the pressure generation outside of the to be operated Clamp may be appropriate.
  • the invention is based on a drawing then explained in detail.
  • Fig. 1 shows a section through pressure medium, actuators actuated by remote control a rotating push rod. To maintain of the frictional connection between a fixed gear 1 and an adjusting gear 3, these are via pressure levers 5 jammed against each other. Press the pressure lever 5 the adjusting gear picked up by a pin 2 3 to a fixed gear; they act on it the ring surface 4 a.
  • the pressure mist 5 is based a support plate 7, which by screws 6 with the Pin extension 2 is screwed.
  • the in a short and a long lever arm divided pressure lever 5 lie with the lower lever arm in each case on a disk 11 on. Between the disc 11 and a paragraph 9a one Push rod 9, a package of springs 12 is arranged, which the necessary to maintain the clamp Preload generated.
  • a piston 20 which rotationally fixed, but axially displaceable in a housing 24 is recorded.
  • the housing 24 takes in one an axial bearing 18 on the push rod side and is via an anti-rotation device 25 with the side wall connected to the machine in a rotationally fixed manner.
  • On a ring of the axial bearing 18 is located on the push rod 9 in axially movable pressure sleeve 13. Between the spring pack side end and paragraph 10 of the Push rod 9 is game, which the switching path 14 permits.
  • the housing 24 has an annular groove 21 in which a sealing element 22 is embedded.
  • the Boundary wall 23 of the piston 20 forms a Delimitation of a pressure chamber 30.
  • the housing 24 has a feed line 26 for a pressure medium and has a further sealing element 27 that together with the sealing element 22, the pressure chamber 30 between the components movable relative to one another, piston 20 and housing 24 seals and build up pressure enables.
  • the housing 24 completes with his Boundary surface 28 between the pistons 20 and Housing 24 annular pressure chamber 30, which is supplied with a pressure medium via the feed line 26 becomes. Through the projection 29 on the housing 24 the recess for receiving the thrust bearing 18th limited.
  • Fig. 2 shows a section through a on a storage drum flanged device for remote controlled Actuation of clamping elements.
  • the piston 20 and the housing 24 are over the Axial bearings 17 and 18 and the radial bearing 19 - analog to the representation shown in Fig. 1 - on the push rod 32 added.
  • the piston 20 is supported on the Thrust bearing 17 at the stop 15 by a lock nut 16 is secured.
  • This through the anti-twist device 25 connected to the side wall housing 24 in takes the piston 20 rotatably but axially displaceable on.
  • the pressure chamber 30 is formed by two annular ones Boundary surfaces 23 and 28 of the piston 20th or the housing 24 is formed.
  • the pressure chamber 30 is through the sealing element 22 in the annular groove 21 of the piston 20 on the one hand and through the sealing element 27 of the housing 24, on the other hand, for a pressure build-up suitably sealed.
  • FIG. 1 A comparison with FIG. 1 shows that the Geometries of the actuators, i.e. pistons 20 and Housing 24 are identical; this results in a universal Usability of these components when used on several components of a turning device. Furthermore, when equipping storage drum and turning drum with the device according to the invention simultaneous actuation of several components achieve. You can also use the in the Figures 1 and 2 also shown embodiments Machines with the device according to the invention retrofit that are already delivered, so that at the delivered rotary printing presses the device according to the invention internally Rationalization potential.
  • Fig. 3 shows a section through a device for remote controlled actuation of a clamp for a Tooth segment, which on the side wall of a rotary printing press is adjustable.
  • a bell-shaped one Body 36 - or a correspondingly shaped one Bracket - on the side wall 38 one Rotary printing press.
  • the bell-shaped body 36 can be attached to the side wall 38 by screws 37 be; to save space, he can also in this be let in, thereby shortening the Push rod segment 39 is accessible.
  • On the Push rod segment 39 is a shoulder 40.
