Definitions

  • the invention relates to a device for clamping flexible printing plates on the plate cylinder of a rotary printing press according to the preamble of claim 1.
  • a printing plate clamping device has become known in which a printing plate end is clamped between parallel clamping surfaces of a plate support fixed to the housing and a clamping strip guided perpendicularly thereto.
  • a movement of the terminal strip takes place via several toggle lever mechanisms arranged axially parallel, on which an eccentric acts, in each case in the area of the toggle lever joint.
  • the eccentrics are arranged on a common shaft and are actuated together when the shaft is rotated.
  • the toggle mechanism moves beyond a stretched position into a stable top dead center position against a stop designed as a second eccentric.
  • the second eccentrics are pivoted against the direction of action of the first eccentrics by means of a second common shaft.
  • a disadvantage of the device shown in DE-OS 26 26 503 is that the pressure plate clamping device must be operated by hand or with tools, which leads to an extension of the set-up times. Automatic actuation is also not possible.
  • the invention has for its object to provide a clamping device for flexible printing plates on the plate cylinder of a rotary printing press, which enables the clamping device to be actuated without tools.
  • the advantages that can be achieved with the invention are, in particular, that tools can be dispensed with when converting the printing press. Consequently, no engagement points for the tools need to be provided on the plate cylinder.
  • the device according to the invention makes it possible to provide remote control or foot control so that an operator has his hands free when converting the machine.
  • a plate cylinder 1 has, in a known manner, an axially parallel pit 2 for receiving a pressure plate clamping device 3.
  • the pressure plate clamping device 3 has a pit-long housing 4 as the main part.
  • the housing 4 is arranged on a base 6 of the pit 2 in and against the circumferential direction of the plate cylinder 1.
  • the housing 4 consists of a bottom part 7 of a left side wall 8 and a right side wall 9.
  • the bottom part 7 has a plurality of bearing points 11 in the axially parallel direction for receiving a lower end 12 of a first coupling 13 of a toggle lever mechanism.
  • An upper end 16 of the coupling 13 is articulated to a lower end 17 of a second coupling 18.
  • An upper end 19 of the coupling 18 is mounted in a bearing 21.
  • the bearing point 21 is arranged below a right lever arm 22 of a terminal block 23 which is rounded at the end.
  • the terminal block 23 has the shape of a T-profile and is mounted with a rounded base part designed as a bearing 24 in a counter bearing 27 in the side wall 8.
  • the counter bearing 27 is a rectangular groove in the side wall 8, which faces the center of the pit with its opening.
  • One end of a left lever arm 28 of the clamping bar 23 is designed as a clamping flap 29 and acts on an upper part of the side wall 8 designed as a plate support 31.
  • a pressure plate end 32 is clamped between the plate support 31 and the clamping flap 29.
  • a guide rail 34 is fastened on an upper side 33 of the side wall 9.
  • the guide rail 34 has a concave recess 36 in the direction of the center of the pit, in which the rounded end of the right lever arm 22 when pivoting the terminal block 23 to be led.
  • a shoulder 37 on the lower edge of the guide rail 34 limits the pivoting movement of the terminal block 23 and forms with its underside, the right side wall 9, the couplers 13, 18 and part of the base plate 7 a pit-long space 39.
  • In the space 39 there is one, or a plurality of pneumatic or hydraulic elements, configured as inflatable, elastic hoses 41.
  • a spring element arranged as a compression spring 43 which acts on one toggle joint 16, 17 each.
  • the blind holes 42 are directed obliquely against the toggle joint 16, 17 in such a way that a deflection of the toggle joint 16, 17 runs almost in the direction of the drilling axis of the blind holes 42.
  • the compression springs 43 are supported on the bottom 44 of the blind holes 42 and press the toggle linkage 13, 18 in the "extended position”.
  • the bellows or hoses 41 are arranged to counteract the compression springs 43 and spend the knee lifting linkage 13, 18 out of the "extended position".
  • a plurality of horizontal bores 47 designed as pressure cylinders are provided in an outer side 45 of the side wall 8 facing the left pit wall 46 in the axis-parallel direction.
  • a piston 48 is mounted horizontally displaceably in each of the bores 47.
  • the pressure cylinders 47 each form a pressure chamber with the pistons 48 in which an inflatable, elastic bellows 49 is mounted.
  • the free end of the pistons 48 is supported on the left pit wall 46.
  • the compression springs 51 are supported on the bottom of the respective blind hole 53 and act horizontally on the right pit side wall 52.
  • a force for moving the toggle linkage 13, 18 into the "extended position" is applied here by a plurality of axially parallel leaf springs 58, one leaf spring 58 being arranged for each toggle linkage 13, 18.
  • the leaf springs 58 each surround with their upper end 59 a pin 57 arranged in recesses 56 of the terminal block 23 and with their lower end 61 a pin 63 arranged in recesses 62 of the base plate 7 of the housing 4.
  • the leaf springs 58 have a curved shape, so that they always act on the toggle joint 16, 17 with their center.
  • the hose 41 is pressurized with compressed air via lines (not shown).
  • the elastic hose 41 expands and bends the toggle joint 13, 18 against the force of the compression springs 43 or leaf springs 58.
  • the lower couplers 13 pivot about the bearing points 11 and pivot the clamping bar 23 by means of the couplers 18 about the counter bearing 27 in the Side wall 8.
  • ⁇ a swivel angle
  • the end of the right lever arm 22 strikes the shoulder 37.
  • the compression springs 43 or leaf springs 58 are fully tensioned and the toggle linkages 13, 18 are bent. This position is shown in dashed lines.
  • the bellows 49 are acted upon by compressed air via lines (not shown).
  • the elastic bellows 49 extend and push their respective pistons 48 out.
  • the pistons 48 are supported on the pit wall 46 and move the housing 4 horizontally to the right against the force of the compression springs 51.
  • the pressure plate 54 which is clamped with its pressure plate end 32 between the clamping flap 29 and the plate support 31 and with its beginning is clamped in a non-displaceable clamping device (not shown) of the same design, is clamped on the plate cylinder 1.
