Definitions

  • the above invention relates to a device for moving and positioning the cutting knives and counter knives which are used for dividing and longitudinal trimming of a paper band in a printing press.
  • each individual cutting device is assigned its own motor, which, using known transmission devices, enables the corresponding cutting device to be shifted into the desired working position with respect to the passing paper tape.
  • the object of the above invention is to avoid the disadvantages of the prior art, and to propose a cutting device of the type mentioned, with which the design effort can be significantly reduced and it becomes possible to perform a shifting and precise positioning individually for individual cutting devices, or to move all cutting and cleaning devices together, automatically and at high speed, provided a single drive motor is provided.
  • parallel sliding guides are arranged on both sides of the paper tape to be cut or trimmed, which are displaceable, the devices equipped with idling or motor-driven knives, as well as the devices equipped with motor-driven counter knives, that the devices, which the idling or motor-driven cutting knives, as well as the devices which accommodate the idling or motor-driven counter knives, is assigned a drive threaded spindle which is arranged parallel to the sliding guides, that the threaded spindles are operatively connected to one another via a transmission means and that one of the threaded spindles is one Drive motor is assigned and that each edging and cutting device has at least one controllable clamping device, which is in operative connection with at least one of the sliding guides, and a device for operating binding or for detaching the cutting and edging device from the associated threaded spindle.
  • the clamping devices are particularly advantageous deformable and actuatable by a medium under pressure.
  • An easily controllable electric motor is advantageously used as the drive motor for the threaded spindle, advantageously a DC motor.
  • the cutting devices e.g. known proximity switches, optical readers or linear transducers.
  • proximity switches or similar detection means are advantageously assigned to the individual cutting devices.
  • the printing machine identified by 1 has two side frames 2 and 3, which are fixedly arranged and represent part I of the machine frame.
  • Parallel guides 4 and 5 are arranged between the two side frames 2 and 3 and accommodate displaceable edging and cutting devices 6, 7 and 8. These devices have bearings 9, 10 and 11 for receiving the disc knives 12, 13 and 14. The knives are advantageously mounted in such a way that they can be freely rotated or driven by a motor.
  • the cutting and edging devices 6, 7 and 8 can be moved on the parallel guides 4 and 5 in the direction of the arrow (f).
  • Each edging and cutting device 6, 7, 8 is also assigned a threaded spindle 15, which is arranged between the parallel sliding guides 4 and 5, which will be described in more detail below.
  • the devices 18, 19 and 20 are also assigned a threaded spindle 30 which is arranged parallel to the sliding guides 16 and 17.
  • each threaded spindle 15, 30 is accommodated in suitable bearings 31 and 32, on the opposite sides the threaded spindles 15, 30 penetrate the side wall 2 and carry toothed wheels 33 and 34 which are connected to one another by a drive means, e.g. are operatively connected by a toothed belt marked with 35.
  • the threaded spindle 15, in addition to the gear 3, is assigned a motor M which is connected to the threaded spindle 15, e.g. with the interposition of a coupling 36 (e.g. type "Harmonic Drive").
  • the motor M consists of a controllable direct current motor, which is connected via known components (encoders, resolvers) is designed as a controllable motor and which can be controlled, for example, via a control unit 37.
  • the control unit consists of a small computer, which is located, for example, near the control panel of the machine.
  • Lengths of the parallel guides 4, 5 or 16, 17 are advantageously arranged proximity switches 38, 39, 40 or 41, 42 and 43, with which the reference position or the initial position of the cutting and edging device 6, 7, 8 or 18, 19 and 20 can be determined.
  • the proximity switches can of course also be replaced by linear transducers, optical rulers and similar known measuring devices, as are already known for recognizing the working position of processing units of large machine tools.
  • Each edging and cutting device 6, 7, 8 and 18, 19 and 20 are control devices 44, 45, 46 and 47, 48 and 49, z. B. assigned compressed air lines, the operation of which will be described in more detail below.
  • Each compressed air line 44, 45, 46, 47, 48 and 49 is advantageously assigned a control valve V, which is designed as a controllable multi-way valve, advantageously as an electric valve (not shown in the drawings).
  • Each valve V can receive control pulses, corresponding to the control signals emitted by the computer '37th
  • the pneumatic electrovalves used are generally known and therefore do not require any further description.
  • a computerized one Control program for printing presses, as offered by the applicant under the name "Cromins" is already known.
  • a detail of the cutting and edging device 6 is shown in cross-section and on an enlarged scale in FIG.
  • the cutting and edging devices 7, 8, 18, 19 and 20 have the same structure.
  • the cutting and edging device 6 has through bores 50, 51 and 52, which are arranged coaxially to the sliding guides 4 and 5.
  • the bore 50 of the cutting and edging device 6 receives, with the interposition of a known ball cage 53, the sliding guide 4, which is advantageously designed as a smooth, cylindrical component.
  • the through hole 50 is sealed by sealing rings 54 and 55 against the ingress of dust. Thanks to the provision of the ball cage 53, the frictional forces which occur between the component of the cutting and trimming device 6 and the sliding guide 4 are reduced to a minimum.
  • the bore 52 also receives a corresponding slide guide 5 with the interposition of a ball cage 56, which also has a cylindrical shape and is arranged parallel to the slide guide 4.
  • the bore 52 also receives a clamping sleeve 57 of the -pk- system KOSTYRKA, as is offered and described in the catalog 9/73 from Gagliani & C. S.a.s., 20125 - Milano, Via Edolo, 19.
  • clamping sleeves essentially consist of a grooved one Metal body that is coated with a plastic jacket, for example made of polyester material.
  • Clamping sleeves of this type as soon as they are influenced by a pressure medium (generally a hydraulic fluid), can, due to their elastic deformation, convert the pressure supplied into a radially acting clamping force, which makes it possible to make a rigid locking between the components involved.
  • a pressure medium generally a hydraulic fluid
  • the sleeve 57 has an annular chamber 58 which is connected to a supply line 44a for the supply of a pressure medium.
  • the hydraulic fluid can be replaced by compressed air by suitable dimensioning of the sleeve 57.
  • sealing means 59, 60 and 61 provided therefor and advantageously, O-rings are arranged on the outer circumference of the clamping sleeve as sealing means 62 and 63.
  • a rotatably arranged threaded nut 66 is provided which has an internal thread 67 which is in operative connection with the thread 68 of the threaded spindle 15.
  • a further clamping sleeve 71 of the aforementioned type is arranged between the wall 69 of the through hole 51 and the outer wall 70 of the threaded nut.
  • the sleeve 71 also receives sealing means 72 and 73 in the form of O-rings
  • a peripheral chamber 74 is provided which is connected to the supply line 54b for the compressed air.
  • the structure described above for the cutting and edging device 66 is identical for all other cutting and edging devices 7, 8, 18, 19 and 22.
  • the threaded nut 66 can no longer rotate freely, and consequently, due to the operative connection between the thread 67 of the threaded nut 66 and the thread 68 of the threaded spindle 15, the cutting and edging device 6 is displaced along the sliding guides 4 and 5.
  • clamping force that is transmitted through the clamping sleeve 57 to the guide 5 is not sufficient to ensure a secure and precise locking of the device, it is of course also possible to assign a controllable clamping sleeve to the sliding guide 4, which in this case is inserted into the bore 50.
  • the supply and the outlet of the compressed air via the lines 44, 44a and 44b are controlled via known pneumatic multi-way valves, which are controlled electrically in dependence on control signals which are output by the computer 37.
  • the computer 37 is advantageously designed as a data processing system, and the control impulses can likewise be emitted by the control panel of the machine.
  • the above invention makes it possible for the first time to move the cutting and edging devices of a printing press individually and to position them in the desired position, with minimal design effort, the displacement movement also simultaneously for all devices 6, 7, 8 and 18, 19, 20 can be done. It is also possible to move individual edging and cutting devices separately, for example to be able to correct the position in the cutting position of the device. All traversing movements take place with the aid of a single drive motor, which acts on both threaded spindles at the same time, but whose rotary movement is selective on the cutting and trimming devices to be moved u eb is borne.
